Making Profits with a Twist †Auntie Anne’s Pretzels

This is a good attitude to have when beginning a business, because it promotes solid values that the business will be based on, even after it succeeds.   It also remembers the people in the community, the customers.   A company will survive and thrive if customers feel cared about and welcomed to the business.   Customers are the livelihood of the business, and it’s important to care about them in the store, and outside it. However, conflicts may arise.   A business may not have enough money to keep itself going, much less give to the community.   A business that suddenly does not give to the community could cause criticism.   It can be difficult to make any profit when a decent chunk of money is going to the community.   A company may take on more than it can really handle when it promises this.   Depending on the size of the community, people may feel they are more involved in the business than they are, resulting in the business not being taken seriously, and possibly failing. 4. How do the advantages and disadvantages of franchise compare to other forms of business? A franchise is a great business for someone who wants to go into business for his/herself, does not have the drive to build a business from scratch (as a franchise company already has a reputation and doesn’t need to build one), and wants the financial backing and security that comes with being a part of an already established business.   The franchisee has corporate support, materials and recipes (in the case of a restaurant) provided.   The only thing the franchisee needs to do is the day-to-day managing, and making some decisions about what products to carry, pricing, etc. However, this also leads to a lack of freedom.   In a traditional start-up business, a person does not have any backing besides his or her own money and possibly reputation as a person in the community.   The company is far more likely to fail (franchises usually don’t fail).   But, the person has the freedom to make any business decision he or she chooses.   He or she can take the business in a new direction, offer or stop offering any products or services, and do anything at all.   There is absolute freedom for a sole proprietorship.   A partnership shares the financial risk, and has some limit on freedom (decisions made equally between all partners), but the business doesn’t arrive â€Å"ready made† like a franchise does. It ultimately depends on what experience a person wants to have – security in business, or freedom to do as she/he pleases. Works Cited McHugh, McHugh, and Nickels.   Understanding Business.

Black Female Executives in Corporate America Essay

Black female executives are a symbol of what determination and hope can achieve that despite the odds and perceptions, people can achieve anything they set themselves on regardless of their cultural backgrounds. Reaching the top for these women has been a journey which dates back way before slavery when women lived and followed the African traditional settings which governed every aspect of their lives. In this setting, the women were subordinate to their men and their duty was to look after their families. Evolution has since changed these perspectives after the civil war that liberated the black people such that they were able to own property and even work in state organizations. In addition, the African people had the power to be educated. Over the years, African women have continually struggled to be the best academically as well as professionally such that they have even outshone their fellow men. â€Å"By 1994, there were more black women as compared to the black men who were employed especially in white collar jobs in corporate America (Tucker, 1994). † Thanks to institutions like Equal Employment Opportunity Commission (EEOC), there has been significant growth of blacks taking up leadership roles in corporate America (Benjamin, 84). In the managerial positions, black men are slightly more than the black women but still the number of women in managerial positions between the years 1982-1992 had increased by 64% (Tucker, 1994). This positive figure has encouraged other black women to undertake leadership roles hence adding up to the increasing figure. Black women representation in the corporate organizations cannot be compared to the rise of white women in the top managerial positions whose numbers have increased over the last decade. This is illustrated by 32% of white women managers who were executive leaders as compared to 14% African American women in similar positions who earned less than them in the year 2000 (Ely, 2003). This shows that as much as the black women are making it ‘big’ there are several factors that hinder their rise to such positions. â€Å"By the year 2001, African American women remained in the shadows and remained invisible hence they were ranked in the corporate businesses either according to gender as well as race (Bell & Nkomo, 2003). † Reasons for lack of black females in executive positions Though there are a few known black women executives in the corporate world it does not necessarily mean that they are not learned enough or that the positions are limited. The major issues limiting the black woman from getting to the top of the corporate ladder are gender and race. Certain stereotypes which are mostly negative are likened to the black female. â€Å"They are considered to be aggressive and very direct (Caver, 2002). † Such characteristics make them unsuitable for leadership positions in big organizations hence limiting their chances of advancing their careers. Black women are not exposed to educational opportunities like their male counterparts as well as white people. This is because most of them come from poor backgrounds and therefore their education is limited up to a certain level when the funds they have can allow. That is why they usually get casual jobs and work as subordinate staff in organizations. Another issue that has contributed to the lack of black females in executive positions is the perception that such positions are the strongholds of men hence organizations mostly employ male colleagues. These factors make it harder for the black women to be promoted to executive positions as they are not only judged by the way their race but also according to gender. Challenges the black women executives face The rise of the women in the corporate world does not really mean that it is all rosy at the top. Though the experience is rewarding some of them are frustrated. The few African American women in executive positions are faced with several challenges in the course of their work. They have to continually convince people and prove to their colleagues that they have what it takes to run organizations. To begin with their salaries are low as compared to those of their fellow black men in similar leadership positions. Most of the African American women in the top managerial positions are considered as vulnerable employees. They are given those positions that can be easily scrapped off when the company restructures itself (Tucker, 1994). They do not therefore get the chance to play major roles in organizations especially in terms of decision making as sometimes they do not have jobs to do. This makes them feel inactive and feel as if they were just put in those positions to enhance the good image of the companies they head as being good an equal employer. â€Å"Some companies just put the women up there so that they can show their corporate allies that they are not biased against any race or gender (Lamont & Molnar, 2002). † †¢ Lack of strategic relationships Relationships define how people will relate with each other in the organization. When the black women are not supported by their employers, then it becomes hard for them to relate with them in proper ways and this affects their work relationship. The relationship between black and white women in the workplace is also strained. This is because white women do not interact often with black women on organizational matters hence they have little knowledge on some of the racial perspectives; the black women have to deal with. â€Å"They feel white women do not care about black women issues and concerns (Caver, 2002). † This has made the black women feel betrayed by them and no wonder they do not relate with them well (Bell & Nkomo, 2003). This scenario has strained communication between the two groups and they never engage in constructive activities. They have been reduced to clicks that support their own members and rarely will they support the promotion of the opposite colleagues to such leadership positions. If the black women cannot relate well internally with their colleagues, it is therefore hard for them to form corporate relationships with people from other organizations as well as their clients as they do not have people within the organization to link them to other business relations. †¢ Lack of mentoring and support African American women are never mentored; and if, on a limited scale. â€Å"This is because they are thought to have nothing in common with their white counterparts as well as black men (Caver, 2002). † Moreover, it is difficult for the black woman to fit in the white male-oriented ‘positions’ which is limited by the negative, historical, sexual racism between black women and the white men (Benjamin, 2005). For this reason, they do not get to improve on their leadership skills hence it is hard for them to be promoted to higher positions. In addition, when other people will start performing better than them, they are said to be incompetent and therefore they risk losing their jobs. The society is also not showing support for the black women corporate leaders who have managed to beat all odds and be the best. This is more so seen in the African American community where people think that they use their high positions to intimidate them. No wonder it is hard for them to find suitable husbands as the males feel threatened. †¢ Trust issues The few black women executives who are there are not trusted to make strategic and informed decisions by other colleagues in the workplace and that is why they have to struggle so much to build this trust which takes a long time. This is why some black women who can no longer cope with the pressure resign from their jobs. This has led to an increasing number of black women quitting their jobs. This is why the CEO as well as other colleagues in the workplace are left to wonder if race determines commonality or whether gender connects across racial lines and if the black women have their own leadership style that helps them navigate in the hierarchy (Bell & Nkomo, 2003). †¢ Lack of access to business development opportunities Leaders need to continually sharpen their skills so that they are able to tackle problems that arise in the business cycle. Black women are usually sidelined in major activities and this limits their chances of growth in terms of acquiring skills and building strategic alliances. For example, a project may be designed which may entail people going for training but surprisingly, countable black women; if any, will be short listed. This makes them feel like an extra burden to the organization. †¢ Balancing work and personal life Just like all women, African American women have to place their families before everything else. They therefore have to ensure that they balance their personal lives as well as their works lest they fail in all of them. Sometimes it is not easy as in every place they are faced with issues and sometimes they do not have colleagues whom they can turn to for help. Impact on the black female work population The statistics might show that black women positions in leadership positions have increased but the experiences of African American women in such positions reveal another thing. Some women have said that they have watched their subordinate colleagues some who are not qualified be promoted to higher ranks while they, who have served the companies for longer periods, are stagnant in the same positions. â€Å"In addition, when they give ideas on anything, they are not taken seriously and this is adding up to their frustrations (Hesselgrave, 2009). † Such scenarios have made them feel diminished, have low self esteem and not feel like part of the organization. This has made them emotionally as well as psychologically disturbed as they cannot come to terms as to why so much hatred and seclusion is still in the society. The lack of back women executives in corporate America is not doing much to encourage young black women professionals to take managerial careers. They see on a daily basis on how their fellow black women in the corporate world are treated and nothing much is done to solve the issues. Some black women have had to succumb to offering sexual favors and bribes if they really want the positions. Such negative factors make the young ladies not wanting to be in such vulnerable positions hence they will opt to choose careers that they find pleasure in. Another impact is that organizations have been divided along racial and gender lines when ‘their own’ are not promoted to executive positions. This has inhibited progress in the organizations as decisions can not be made effectively because employees are not communicating and they are not performing well at their work because their issues are not being addressed. â€Å"This has also brought in unhealthy competition in the workplace as the different groupings of people have to find fault in each other so that they can use the raised issues as an excuse to make them appear better so that they can be favored (Ivancevich & Gilbert, 2000). † In some instances, it has led to the formulation of policies which the minority group in this case, the African American women, use to give them an edge over other colleagues. Recommendations Women of all races play a major role in corporate organizations and that is why they should be encouraged to take the top most leadership positions if they are qualified. Some of the factors that need to be considered in promoting African American women in leadership positions include: ? Encouraging more black women to pursue leadership positions Educating and sensitizing the young black girls at a young age is important so that they take up leadership courses. This will make them more open minded at an early. The Federal State therefore should ensure that there is equitable distribution of resources such that black children can access proper schools like the rest of the children in major cities. African American women also need to be trained on political skills so that they are able to lead people in the proper manner thus become competent. ? Equal treatment Affirmative actions and the formation of women movements have played a vital role in rallying for equal treatment of women. More needs to be done so that the women can feel like they are part of the organizations they serve. The managers should therefore diversify employee groups and continually monitor to see how they are progressing and help then overcome the challenges they face. â€Å"The top managers should also be able to identify black women who are skilled and help them grow within the organizations they head (Lamont & Molnar, 2002). † The human resource heads should therefore ensure that they recruit they staff equitably and not based on any kind of biasness so that when it comes to making decisions or selecting the right candidate for a particular top office, all the people will be represented therefore the right candidate will be chosen regardless of their back grounds. ? Respect and trust Respect starts with an individual when they identify their needs and they treat others the way they would like to be treated in return. Respect is a very important virtue that should be in every code of conduct since it determines how people will be treated. â€Å"Sometimes when white male superiors and black female subordinates as they are trying to amend their relationships they are faced with difficulties because of the lack of basis for identification which is mainly attributed to the fact that the motives behind them are not sincere (Thomas & Gabarro298). † Without respect, then there is no trust as individuals will not trust people who treat them badly. People therefore need to learn to respect black women because it is the only way that will help them salvage their relationships, ease communication and enhance understanding each other so that productivity of the company can improve. It is also advisable to find trust agents if the matters in the organizations are too complex for the members to solve. Having an independent party helping employees and management to solve their problems will be good as they will not be biased. ? Educating the other employees on the negative effects of discrimination is also a positive step towards creating room for black female executives. Conclusion Operations in organizations are changing slowly by slowly to accommodate cultural diversity and people are beginning to embrace the work done by the black women as well as other minority groups. Black women executives nowadays can be found in almost all departments in the workplace and have even gone a step further to head multinational organizations. â€Å"Even in the wake of civil rights and women movements which have helped bring about gender equality, black women executives still face many challenges. African American women need to work harder to face out racism especially in this ever changing diverse world (Burk & NCWO). †These women need to be supported in the work they do rather then being put down as they are also human and they deserve respect just like other individuals in similar positions in the society. Corporations therefore need to change their cultures and philosophies so that they attract more black women and retain them. Black women also need to show that they deserve the executive positions by being passionate about the jobs and ensuring that they are qualified for the positions. References Bell, E. L. J. & Nkomo S.

Critical Thinking questions - Essay Example Financial accounting and managerial accounting basically have the same function but their end results are different. The main difference between the two is that financial accounting is conducted and processed so that information can be made available to third parties that are outside the organization. These reports are basically created over a half yearly or annual period and they are reviewed as per the fiscal year. Managerial accounting is more centered towards decisions that have to be made within an organization. The data and information procured during this process is used by the managers of a business or company. The reports that are created under managerial accounting are for a shorter period of time for example a week, a month or even everyday. Financial reports are used by people who may want to invest in the firm or sell the stocks or shares, where as managerial reports are needed for the smooth running of the firm. Financial risk and financial return can be called siblings in a sense. When an investor is putting capital or money into stocks, bonds or generally putting money into a firm he is taking a considerable risk because there is always a chance that he may lose the money that he has invested. Financial return on the other hand is the profit that the same investor would get from his investment. The amount or significance of the return is dependent on the risk i.e. the lower the risk taken, the lower the return will be and the higher the risk taken the higher the return would be. There is always a potential for higher returns based on the risk being a success or failure, if it results in a failure then there will be no returns.

Childhood Obesity Research Paper Example | Topics and Well Written Essays - 1250 words - 1

Childhood Obesity - Research Paper Example It should also be noted that children are becoming obese at a younger age and as Ebbeling et al (2002) put it, this can be highly attributed to the sedentary life lived for most part of the day at school. Arguing from Ebbeling claim, it is evident that many obese children take little or no time to engage in physical activities. Research indicates that children age 6-11 are vulnerable to obesity because of the nature of life they lead. For example, a child goes to school by bus, takes most of his time in class seated, and goes home by bus. This child may have no time to engage in an exercise that would result into sweating. Healthy living guides demand that children should engage in physical exercise in order to make them active. Many parents are not aware of the danger involved when a child does not take any exercises. Method of data collection For this research, questionnaires will be used as the method of data collection. The questionnaires will be designed in such a way that it wi ll allow the obese children, parents and teachers or social workers to respond. This will ensure that adequate information is collected relating to the child’s eating habits and level of activity both at home and school. Data collection will take place at home and school with the consent of the teachers and parents. Another method of data collection would be research information obtained from libraries. This information would help to identify aspects that promote obesity among children. Preliminary findings Results obtained so far indicate that many children in the US are becoming obese at a younger age and at the same time; there is a rise in the number of pre-schools in center-based programs (Peiser et al, 2005). According to the findings obesity cases in... The paper tells that main cause of child obesity is physical inactivity is important because childhood obesity is steadily affecting low income and middle-income countries. This means that childhood obesity is not just about eating in excess or getting a lot of calorie-rich drinks and foods. It should also be noted that children are becoming obese at a younger age and as Ebbeling et al put it, this can be highly attributed to the sedentary life lived for most part of the day at school. Research indicates that children age 6-11 are vulnerable to obesity because of the nature of life they lead. For example, a child goes to school by bus, takes most of his time in class seated, and goes home by bus. This child may have no time to engage in an exercise that would result into sweating. Healthy living guides demand that children should engage in physical exercise in order to make them active. Many parents are not aware of the danger involved when a child does not take any exercises. The re port recommends increase in time allocated for physical exercise among children in school. Another recommendation of the report is to limit time taken by children playing non-physical games. This will lead children to active participation. In conclusion, obesity is a disease that results from accumulation of too much fat in the body. Obesity leads to low self-esteem, social stagnation and health complexities. Research findings indicate that physical inactiveness of a child promotes obesity among the children. Largely, accumulation of fats in the body results from eating without spending the same amount of energy.

An Argument Supporting a Thesis on the Effective Use of English Essay

An Argument Supporting a Thesis on the Effective Use of English - Essay Example Additionally, whenever a person wishes to travel to a place in the globe, they have to communicate throughout their journey. For instance, if a person does not understand the language at a place in the globe, he or she would communicate their concerns to those inhabitants through talking English. If we could imagine of a person who does snot confer the English language travelling to a distant land whose language they may not understand, they would find it extremely intricate to express their sentiments. Thus, it is a benefit to learn and comprehend the English language. Communicating in English with a foreigner would be an easy thing to do, since numerous people have an understanding of English. This explicates on the reason behind why most media publications are expressed in the English language. These publications include newspapers, magazines and broadcasts. If one gets a magazine or newspaper and are interested in reading it, he or she would pick it and start reading. If they do not understand the English written in the initial sentences, they would stop reading the newspaper. Another advantaged person with prior knowledge of English would read it comfortably. Tan has communicates in different English languages, something that she notes peculiar (Tan). She asserts, â€Å"It has become our language of intimacy, a different sort of English that relates to family talk, the language I grew up with.† Thus, the truth that her environment implicated on her English quality proves that backgrounds immensely contribute to incompetence in talking in effective and perfect English. In the case of immigrants from a distant country seeking, employment or residence in a neighbouring country, prior knowledge of the English language would aid them in interacting with workmates or neighbours. Since English appears to be the most commonly used language for instruction and communication in workplaces, it is pertinent and an added advantage if the immigrant understood how to communicate effectively in the language. Knowledge of English as an instruction language would minimize erring and people would interact effectually with their counterparts. Ability to organize themselves coherently in communication of their sentiments to their counterparts or fellow people, immigrants can be at a merit. For instance, Rodriquez had an immense challenge in speaking English and was disadvantaged when communicating with other English speakers. He asserts that they had to bend lower to hear what he was saying properly (Rodriques 154). This shows how important English language is for immigrants, since Rodriquez must have communicated in English to express his sentiments. Additionally, those immigrants who are in the process of seeking employment in chief industries or companies would have an advantage if are conversant with English speaking. Conversely, their counterparts who have no experience in communicating in English fluently would have a hard time procuring emp loyment. This means that English speakers are at an elevated advantage than those who are not competent in the English language. Because effectual communication is a pertinent activity when operating in the workplace, people who can communicate effectively in English always have an added advantage than their counterparts. In the case of Malcolm X, he felt that he was having difficulties even in writing a simple letter to Muhammad (Malcolm X). He was overly frustrated and could not articulate himself properly and effectively. However, his prison

The Wagmatcook Cultu re & Heritage Centre opens daily, all year-round (Wagmatcook.com, 1). Cape Breton Island, where Wagmatcook Culture & Heritage aboriginal site is located, is in the Nova Scotia province of Canada. It is a 3,981  sq  mi (10,311  km2) island, which is 18.7% of Nova Scotia’s total area. Even though, the Strait of Canso physically separates it from the Nova Scotia peninsula, they are artificially connected by the Canso causeway for easy transport. Cape Breton’s landmass upwardly slopes from south to north, hence culminating in the Northern Cape islands. The first residents of the Cape Breton Island were the Maritime Archaic natives who are ancestors to the Mi'kmaq people who were the island’s inhabitants at the time of discovery by the Europeans (Wagmatcook.com, 1). The Wagmatcook people history dates back many centuries. The reservation was, however, not established officially until May 2nd, 1834 by Sir Peregrine Maitland. He has been referred as the gentleman who refused to accede to the Scottish settler’s wishes of removing the Native people from the West-Side Middle River’s mouth. The centre’s operation is part of the five year development strategy by the Wagmatcook Band Council. The Wagmatcook Culture & Heritage Centre’s future plans include featuring an interpretive village offering marine opportunities and outdoor activities and travelling exhibits (religious and medicinal themes).

There is a variety of souvenirs available for sale including; beadwork (bookmarkers, necklaces, etc.), baskets, earrings, bracelets

In and out of cloud computing Literature review

In and out of cloud computing - Literature review Example In an attempt of trying to gain a competitive advantage, businesses are eagerly looking for innovative ways of maximizing profits, while cutting down costs. Their growth ambition is normally hindered by money saving pressure. They therefore try new methods and ideas, which they think can produce better results than what they tried yesterday. It is this innovative technologies growing acceptance that has made clod computing to be the IT’s biggest buzzword (Basset 1997, P.13). However, it is very important for any organization to fully understand what, how, why, and from whom ideas, before jumping into cloud computing. Providers of cloud computing are not the same and their services are different in range and quality, and hence, it is advisable that potential users do a thorough investigation into the nature of services they are bound to receive. According to Basset (1997, p.15), the main economic appeal of cloud computing is that it allows customers to only use what they need a nd only pay for what they use. These resources can easily be accessed at all times from the cloud, from any location, through the internet. It is also called ‘IT on demand’ or utility computing because you simply buy your required IT service, just like any other utility. It makes use of remote servers, which are housed in data centers that are highly secured for data management and storage. Therefore, organizations have no need of buying and looking after their in-house IT solutions. This review aims at assessing the extent to which cloud base computing can replace in-house. Literature Review Key Concepts of Cloud Computing Cloud computing can be seen as a pyramid of three sections. At the apex is cloud application. This is where applications are interacted and run through a web browser, re mote client or hosted desktop. Cloud application removes the install and run application need in the computer of the customer. This removes the need for support, ongoing operations, and software maintenance. Johnson (1998, p.107) asserts that the cloud platform is in the middle, and provides a service framework. It dynamically configures, and reconfigures servers according to the need to cope with decrease or increase in demand. The cloud infrastructure forms the pyramid’s foundation of IT infrastructure via virtualization. It includes, networks, servers and hardware appliances, which act as â€Å"web servers†, â€Å"cloud centers† or â€Å"farms†. Johnson (1998, p.108) concludes that interlinking these with others provides additional capacity and resilience. There are three types of cloud computing namely private, public and hybrid. The public cloud is also called the external cloud and describes cloud computing as often virtualized, dynamically provisioned, and scalable resources that re readily available in the internet, from a third party provider, who is normally off-site, for example ThinkGrid. Private cloud is also referred to as internal or corporate cloud, and denotes a computing architecture that provides a host of private services. It is used by many large companies, but negates many cloud computing benefits, because such companies will still need to buy set up and monitor their clouds. Hybrid cloud combines providers of internal and external resources, thus becoming enterprises’ most popular choice. There are many services that can be achieved via cloud computing by taking advantage e of

Why Did the United States Enter World War One Essay Example for Free

Why Did the United States Enter World War One Essay The industrial era had many effects, not the least of which was plunging the world into world war. One must consider the relationship between eras and events as a student of history. The industrial era created a perceived need in America for raw materials and markets for goods. The United States was not alone in this desire for expansion. All the industrial nations were in open competition to develop vast empires that would provide them with the fuel to run the factories of industrialism. This imperialist competition led to tension and the creation of vast armies. The willingness to use these armies was known as militarism. In order to feel safe (there was a pretty fair degree of paranoia as you can imagine) nations began to sign secret treaties formingalliances and Europe was divided into an armed camp. Tension was high, the subjugation (taking over) of other nations led to feelings of nationalism that would eventually light the spark that would explode Europe into the flames of conflict. The causes of World War One as discussed above can be summarized by the following acronym as a mnemonic device: A- Alliance: European nations signed secret treaties that created a system of alliances pitting nation versus nation. N Nationalism: There were intense feelings of nationalism on the part of subjugated nationalities. These feelings would eventually lead to rash acts. I Imperialism: Competition to develop vast empires caused tension and conflict. M Militarism: Nations built huge armies to defend themselves and help to gain these empires. It was a natural feeling for them to want to use these militaries. A Anarchy: There was no international organization to help them deal with their problems. L Leadership: It was poor. Just look at the system they set upquite poor indeed. These were the conditions facing Europe as a crisis emerged in the Balkans. The Archduke of Austria Hungary, a traditional power, was touring the nation of Serbia. Meanwhile Bosnian nationalists desiring freedom from Serbia plotted to assassinate the Archduke. Gabriel Principe, a member of the Black Hand, the aforementioned Bosnian nationalist group, shot and killed Franz Ferdinand on June 28th 1914. Austria Hungary blamed the Serbian government for the assassination of the  Archduke and issued an ultimatum (demands). The Serbians agreed to all but two of the demands, one of which was the placement of Austro Hungarian troops within Serbia. The Serbians appealed to Russia for support and Russia as the protector of the Slavs agreed to support Serbia. Meanwhile the Austro Hungarians still wanting revenge and fearing Russia secured the support of their traditional ally, Germany. In a famous decision Germany issued what has become know as Carte Blanche, of blank check, to Austria Hungary. This unqualified military support from Germany made Austria Hungary rather confident that Russia would not attack. At this point the Austro Hungarians declared war on Serbia. In response to the declaration of war Russia mobilized her military forces. Perhaps it was a bit of saber rattling, perhaps not. Regardless Germany demanded Russia demobilize its army. When Russia refused Germany attacked Russia. The effect of the war on the Russian front were devastating. The Russians were ill prepared for war and lost millions of men. In the end the Czars refusal to exit the war cost him his throne as the Bolsheviks (Communists) revolted in 1917 overthrowing Czar Nicholas II. When the Russians were attacked by Germany, France was obligated to declare war on Germany as a result of a treaty she had signed with Russia. The Germans attacked France by marching through Belgium. The Belgians who did not give Germany permission to do this now were in a state of war with Germany as well. The most important byproduct of this was the fact that England had a treaty with Belgium! Now England was obligated to declare war on Germany as well. Italy, which had a treaty with Germany switched sides so that she might gain territory from Austria Hungary (A gamble that more or less worked) and the Ottoman Empire entered the war on behalf to the Austro Hungarians (they wanted to gain territory from the Russians and gain control in the Balkan region). Now most of Europe was engulfed in war. In the end the Triple Entente (England, France and Russia later to be joined by Italy, the United States and Japan) defeated the Triple Alliance (Germany, Austria Hungary and the Ottoman Empire). The conflict which was long and bloody was marked by trench warfare and the use of chemical weapons. It was fought mostly in French territory. At the conclusion of  hostilities Germany was still in French territory but it was relatively clear that the combined industrial might of the Triple Entente would prevail. In actuality the influence of the United States is questionable. Germany hoped to negotiate a favorable treaty but as we shall see this was not to be the case. The Treaty of Versailles was signed ending the war and blaming Germany for the entire conflict. This blame and the consequent punishment set the stage for years of resentment and another world war, something American President Woodrow Wilson had hoped to avoid. So, what did all this have to do with America and why did we enter World War One? Most Americans favored staying out of the conflict and President Wilson publicly and formally stated that the United States would follow a policy of neutrality. In three short years, however, the United States would find itself in the middle of what later became known as the first World War. As the war in Europe raged on America sympathies were clearly on the side of the allies. American propaganda posters urged citizens to buy war bonds and support the allies. The Kaiser and Germans were painted as the aggressors in the war. True or not Americans came to see Germany as vicious and blood thirsty. The poster below was used by the US Army in 1917 to recruit soldiers. Notice how the Germans are pictured? This is a clear example of anti German propaganda. When the war began England enforced a naval blockade of Germany in the hopes of cutting off supplies. Germany responded by unleashing the U Boats. U Boats were submarines capable of staying submerged for long periods of time. They would sneak up upon their victims, often at night, an torpedo them. The Germans did not limit their attacks to military vessels. Any ship sailing in the war zone was considered an enemy. This became known as unrestricted submarine warfare. On May 7th 1915 the British cruise ship Lusitania was sunk off the coast of England. Over 1,198 passengers including 128 Americans were killed. America was furious at the brutality and demanded a stop to this type of attack. In 1916, after the sinking of the passenger liner Sussex, Germany agreed to end unrestricted submarine warfare in the Sussex pledge. The Sussex pledge only put off the inevitable American entry into the war. America shared acultural bond with England and France. Woodrow Wilson began to actively campaign for Americans to support the allies. Besides being culturally similar England and France  were our trade partners. From 1914 to 1916 trade with the Allies grew from 825 million dollars to 3.2 billion dollars. If the Allies were to lose the war our trade would be threatened. American increasingly saw Germany as the enemy. Germany was a dictatorship fighting against the great democracies of the world and America as a democratic nation felt an obligation to support them. As America became increasingly less neutral, the British government intercepted a message from the German ambassador Zimmerman to the Mexican government. This message termed the Zimmerman Note asked Mexico to attack the United States if war broke out between the U.S. and Germany. The note was turned over to American government a short time later and eventually published in the newspapers. Americans were outraged. Then the Kaiser announced that Germany was going to re initiate the practice of unrestricted submarine warfare violating the Sussex Pledge. Wilson had campaigned for office promising to protect freedom of the seas and now it seemed he had little choice. He had to ask Congress to declare war. Many Americans still wanted to stay out of Europes war and there was much debate in Congress. Wilson closed his speech to Congress by saying it is a fearful thing to lead this great peaceful people into war But the right is more precious then peace and we shall fight for the things which we have always carried in our hearts. On April 6, 1917, by a vote of 82 to 6 in the Senate and 373 to 50 in the House of Representatives, the United States of America declared war on Germany. Wilson strongly believed that the American system would save the world, meaning: 1. American economic goods 2. Americas democratic political structure 3. Americas blend of morality and Christianity Wilson stated: When properly directed, there are no people in the world not fitted for self-government. Note the caveat, when properly directed. Wilson saw the U.S. as the rightful and natural director. He was determined to provide that direction in a framework where morality, democracy and economics were closely related. Wilson believed that other nations of the world had to look to the U.S. as an example, at the same time America was dependent on the rest of the world, mostly for economic markets. The world market must act as the new frontier for the American system. Wilson was determined to direct the affairs of other nations so that they could eventually achieve self-government, as long as this government was based on the American model, and he was even more willing to intervene in other countries than Roosevelt. For instance, he sent U.S. troops to Mexico to intervene in their civil war (1913-1917). When World War I broke out in Europe in 1914, Wilson tried to keep the U.S. neutral, but Germany repeatedly violated Americas neutral status. When America finally entered the war in 1917 it was because, as Wilson stated, The world must be made safe for democracy.

Food safety Essay Example for Free

Food safety Essay Food safety is a very essential aspect of maintaining healthy and productive relationships between human beings and the entire environment. It is because it plays a basic role in enhancing good health which is vital in influencing sustainable human activities. Fundamentally, human activities influence their relationships and interactions with the environment. It can be acknowledged that maintaining food safety at all levels ensures good health which in turn guarantees healthy relationships between man and his environment. Human activities have various implications on the entire environment. In deed, they affect the economic, social, environmental and political aspects of the environment. Food safety that is fundamental for good health enables man to relate well with all these aspects of his environment. Food safety: Health To begin with good health enables human beings to work hard and be able to provide for their economic needs. According to Last (1998), when both mentally and physically healthy, individuals tend to be more productive. Increased productivity leads to healthy societies as individuals can be able to cater for their needs and wants. This is made possible by individuals earning enough to attain financial stability. Thus they can be able to pay their bills, spare some for recreation and also be able to save for the future. This is made possible if their health is assured through ensuring food safety. Bronfenbrenner (1979) indicates that excellent health also determines good interpersonal relationships and hence enables populations to acquire social cohesion. In this respect, he argues that healthy individuals are unlikely to be social misfits because they are able to think straight and are also conscious of the societal values which they uphold. Also, health enables one to work and earn an honest living as well as provide enough for his or her family. As such, people become more responsible and dedicated to their lives and this enhances one’s self esteem and personal satisfaction. Generally, Last (1998) asserts that healthy people are able to maintain healthy relationships than their counterparts. Again, this healthy status can only be achieved if the they food they consume is handled in a hygienic manner. With regard to the environment, Ebi, et al. (2005) argues that good health enables individuals to cater for their environment. According to him, healthy individuals are usually able to take timely measures to avoid environmental deterioration in their own simple ways. For instance, they can be able to plant trees, dispose of their wastes in a proper way and perform other functions that enhance environmental conservation. These actions may seem simple yet their contribution to environmental conservation is very significant. In addition, since these individuals have financial stability, they can contribute to environmental conservation missions by donating money (Ebi et al. , 2005). Furthermore, healthy individuals are in position to take sound decisions with regard to environmental conservation. The political stability of a country is also dependent on the health of the individuals. To this end, Bronfenbrenner (1979) argues that healthy and active individuals are less likely to engage in politically unsound behavior. It is worth noting that good health throughout a person’s life also implies that the person’s education and thinking process is rational. Therefore, such individuals are able to make informed, autonomous and democratic decisions with regard to politics. This enables a country to have visionary leaders that are politically mature and therefore enforce policies that are beneficial to the locals. This status can be achieved if food safety is maintained all through a person’s life. Indeed, food safety is a very vital component of our day to day living because of the role it plays in maintaining our health. Without this good health, life can be difficult for most individuals because diseases will be prevalent. Despite this realization, food handling in the US continues to be a major problem and the frequency of food poisoning and food borne illness continues to rise significantly (Last, 1998). This implies that the Food and Drug administration has failed in its duty to protect the health of the citizens. This can also be attributed to the money oriented attitude that our society has assumed. For instance, Andrew (2006) indicates that some butchery workers would rather keep their jobs than identify a slip up in the meat processing process. Further, he asserts that the urge to get food on the markets in a timely manner in order to make huge profits has made business persons overlook the minor but most important aspects of food safety. Therefore, there is need for consumers to take up the responsibility of maintaining good health by practicing the following critical steps that are very important in enhancing food safety and improved health. At a personal level, consumers should be extremely wary of sale offers. If the deal seems too good, it is always recommended to think twice. In most instances, business owners place on sale products that are defective (Andrew, 2006). Therefore, instead of making purchases blindly, consumers should spare time to check the packages properly and even identify the odor of the food. If the odor is bad, Loken (1995) ascertains that such food is not suitable for human consumption. In addition, consumers should put in to consideration the packaging of the food. Usually, food can look very appealing yet if not packed well, the probability that it is infected is so high. According to Watson (2001), well packaged food has a higher probability of being germ free. When purchasing fruits and vegetables, consumers should only buy those that are fresh looking (Loken, 1995). They should avoid fruits or vegetables that have spots or look unhealthy as this is a clear indication of infection. Andrew (2006) notes that hepatitis A is spread through poor handling of fruits and vegetables, specifically by washing the same with contaminated water before they reach the market. He suggests that it is important that consumers keep themselves well informed about any outbreaks and take precaution in a timely manner by adjusting their menu accordingly. According to him, it could be safer to avoid any fruits or vegetables involved in the outbreak than endanger one’s health by consuming contaminated food. At home, fruits and vegetables should be washed thoroughly and under running water in order to remove all dirt. In cases where fruit and vegetable washers are used, it is essential to adhere to the directions of the manufacturer in order to avoid any possible contamination. When shopping for dry foods, Watson (2001) argues that consumers should check the packaging material to ensure that it is in order. In particular, he explains that the nylon papers used for packaging as well as boxes should be well inspected to ensure that they do not have holes or openings. This is an indication that food is not contaminated as holes or other openings could serve as entrances of insects and generally germs. In addition, consumers should avoid buying dry foods that are infested by insects like weevils. These transmit diseases that are dangerous to human health. In the case of canned foods, Loken (1995) explains that care should be taken to avoid buying any cans that are defective in any way. Specifically, those with punctures or dents should be avoided at all costs as this is an indication that the food is contaminated. Consuming infected canned food can be very fatal as it may contain botulin toxin (Watson, 2001). This has a severe and fatal impact on human health as it causes paralysis. It is also important to check the cans properly on arrival at home as dents can occur during transportation. In such incidents, Andrew (2006) explains that it is better to discard them as this could be an indication of punctures which imply infection. In the home environment, Andrew (2006) points out that it is advisable to clean all surfaces used in food preparation and the kitchen as a whole after the activity. This should be done with an antibacterial cleaner in order to kill all disease causing micro organisms. In addition, the surfaces should be kept dry as wet surfaces, coupled with a warm kitchen environment provides the best conditions for micro organism breeding (Andrew, 2006). When handling meats, Loken (1995) indicates that it is advisable to freeze any that would not be consumed in a few days time. According to him, this goes a long way in avoiding chances of poisoning. In addition, he explains that before cooking any meats, it is important to inspect them fully after thawing in order to identify any signs of spoiling. Further, when cooking meats, the right temperatures should be used in order to kill any existing infectious micro organisms. Failure to do this could lead to fatal poisoning caused by the existing micro organisms (Loken, 1995). After meals, any remaining food should be frozen rather than left open even if it is meant to be used in the next meal. In many cases, persons prefer to leave the left over food from the previous meals intended to be used in the next meal in an open place. It is assumed that the period between meals is short and therefore possibility of contamination is low. However, Watson (2001) indicates that contamination can still occur within any period. The surfaces used when preparing food before cooking should also be easy to clean appropriately. It is notable that most people prefer wooden boards for chopping food and vegetables. However, these are not hygienic enough as they keep germs between the chips. It can be very difficult to clean them appropriately. Therefore, other options found on the market should be used. In cases where a dish washer is available, it should be utilized for washing utensils. Dishwashers have proved to be very effective in killing germs due to their ability to withstand very hot water. Andrew (2006) affirms that in deed, hot water is the cheapest way of killing germs and consequently, dishes washed in very hot water are likely to be germ free. In instances where one opts to dine in the restaurants, the first thing to do should be to choose a decent place. Then, when inside the restaurant, one should take note of the conduct of the staff when serving food as this often gives an insight on the general hygiene of the restaurant. If this is not satisfactory, Last (1998) explains that it is better to avoid eating in the place than risk infection. Particularly, care should be taken before consuming vegetable and fruit salads as they are the most susceptible to contamination. Restaurants on their part should ensure that any food bought is well tested before it is cooked. This is important as it helps avoid chances of cooking infected food. In addition, hospitals should also take the same precautions. Above all, Watson (2001) argues that Agricultural production in itself should be sustainable to avoid contamination at the farm level. According to him, this can be achieved if the chemicals used are suitable for Agricultural production. Harsh chemicals that are risky for human consumption should be avoided at all costs. This will help avoid the incidences of heavy metals in the vegetables and fruits. Traces of heavy metals in food have been known to cause terminal illnesses like cancer (Watson, 2001). This can be avoided if more healthy Agricultural practices are adopted. Conclusion In conclusion, all these safety measures if put in to consideration can have a positive effect on the healthcare of individuals and the society a large. Specifically, these measures are fundamental in avoiding infection as a result of consuming contaminated food. If infection is completely eliminated from food preparation and processing, then the food eaten will be safe and this has a positive impact on the health of individuals. Eating safe foods significantly reduces the incidences of disease and deaths. Since diseases cause a major setback on people’s health, elimination of the same in the society will aid in creating holistic and productive societies.

The effect of traumatic events on memory

The effect of traumatic events on memory Memory Scientists have keen on pressuring secrete of memory for hundreds of years, undoubtedly, obliteration and inheritance are one of the most mysterious and romantic subjects. Dominick Cobb plants memory in Robert Fischer via a designed dream, changes his subconsciousness thus influences his reactions in reality, Inception. These kinds of stories are no longer restricted in friction movies. Nowadays memory is ahottopicinneuroscience,notonly enhancingit,but erasing or inheriting it. Before we explore how to delete traumatic event, it is necessary to briefly understand how our brain works to remember an event. Information transmits from the outside through our vision, auditory, olfaction, taste and tactile. Memory is the ways that we store and evoke items weve sensed. Different types of memories therefore stored differently. There is a structure in the brain called the hippocampus that is key to short-term memory, which only responses to the data that catches our attention (fire alert) or we need it soon (a telephone number). Long-term memory is much more complicated, it involves three main processes: encoding, reserve and retrieval. First of all, encoding: new concepts are broken down into composite parts to establish various meaning. Moreover, we collect the context around us when we receive a new conception, or another episode occurs in our life. For instance, I might associate the phrase beautiful flower with its key descriptive ideas —white color, faint scent smell, elliptical petal, floating in hometown pond — and thus such contextual memories as it is such happy summer that I’m swimming beside these lotus with my brother. Reserve: when we store the newly-caught episode, we attach it to any other related memories, such as similar to magnolia but living in the shallow water, and hence, consolidate the new conception with older memories. After above processes, we recall the conception, by tracing the various meaning codes stored in our brain and decoding these consolidated memories to regain a new meaning. If I forget what beautiful flower means, I might think of its relative pointer-hints, such as white or hometown pond. Pointers associate with other pointers that even a single hint may let me to recover the whole context. Then the following question is: how do our brains transfer a short-term memory like beautiful flower and into a long-term memory? We use hippocampus again; temporary links are constructed among cortex neurons due to a short-term memory event. For example, white gets stored in the visual region of the cortex, and the faint scent of a blooming flower gets stored in the olfactory area. When I remember the new fact, beautiful flower, it will converge on my hippocampus, which sends these new memory data along a established path several times to strengthen internal links. â€Å"The short-term memory flows alone the path, with the beginning at the hippocampus, circulating through several limbic systems (to pick up any timing associations like early morning on June 1st, and spatial associations like bond street station), then pass over various parts of the cortex, finally back to the hippocampus. Making the information flow around the circuit many times strengthens the links enough that they stabilize, and no longer need the hippocampus to bring the data together, says neuroscientistBruno Dubucof the Canadian Institutes of Neuroscience, Mental Health, and Addiction. â€Å"The strengthened memory paths, enhanced with environment connections, become a part of long-term memory.†[1] Recalling memories re-fires many of the same neural paths we originally used to sense the experience and, therefore, almost re-creates the event.[2] In other word, memory just like glass, it behaves plastically during storing memory and eventually fixes shape at the end of process. When we recall this memory, it will be abstracted and activated from the cortex, becoming soft and plastic again, memory reshapes its structure instead of the original one. Taken in this sense, theoretically, memory manipulation and obliteration are reasonable and realizable. When a distressing event occurs, a fearful memory created that could last a very long time period and depressingly affect a person’s life. Researchers from the University of Toronto trained mice to terror a sound by matching that sound with an electric shock to their feet, so when the sound rang, the mice would freeze in fear. This sense of feeling can be relieved by training called â€Å"extinction training†: repeatedly ringing the tone without adding electric shock. Behavioral therapy built around such â€Å"extinction training† in mice models has proven that it is useful in decreasing the degree of negative emotional response to a traumatic memory, however these fear memories commonly relapse and rarely can be completely removed via this kind of physical training. Further study focuses on the amygdala, a part of the brain located at the end of hippocampus, known to response to fear conditioning in both people and animals. Using sound to threaten the mice, they detected that certain cells in the nerve circuits in amygdala conducted much more current after playing a loud, sudden sound around the mice than they stay in a calm, normal environment.As for rodents, the neural functions capacitating fear memory formation and correspondently reconsolidation are situated in the amygdala. As for humans, brain and lesion imaging analysis confirm that most of fear memory mainly encoding in the key area—amygdala. Memories become labile when recalled. In humans and rodents alike, reactivated fear memories can be attenuated by disrupting reconsolidation with extinction training. Using functional brain imaging, we found that, after a conditioned fear memory was formed, reactivation and reconsolidation left a memory trace in the basolateral amygdala that predicted subsequent fear expression and was tightly coupled to activity in the fear circuit of the brain. In contrast, reactivation followed by disrupted reconsolidation suppressed fear, abolished the memory trace, and attenuated fear- circuit connectivity.[3] The team then observed and recorded the proteins in the certain nerve cells we mentioned before in the amygdala during the whole scary experiment. A sort of particular calcium-permeable proteins temporarily spiked in the lateral amygdale. Because these especial proteins are uniquely unsteady and able to be removed from the amygdala, the scientists suggested that fear memory might be permanently removed by combining protein removal and behavior therapy, which provides a opportunity for erasing fear. In further experiments, information revealed that eliminating these particular proteins depends on another chemical modification protein called GluA1. Now,whenhorrificsoundrang,themiceon longer felt fear and continuedtheirmouse-likeactivities.Neitherotherreserved memories, northeirabilitytosavenewmemories,wereinfluenced.Theeffectof using this biochemical method wasspecific,effectiveand long-lasting. Scientist notices that memory erasure can be achieved by using drugs designed to control and enhance the elimination of calcium-permeable protein. Another interesting property of memory is inheritance. Behaviour can be affected by events in previous generations which have been passed on through a form of genetic memory. Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations. [4] Currently a neuroscience studyreveals that after training a group of mice to avoid a particular smell; their aversion could pass on to their descendents. Scientists said that the results were essential for fear and anxiety memories research. The mice were trained to panic a cherry blossom smell. The further study focused on internal structural changes inside the mice sperm. The team at the Emory University School of Medicine, in the US, pointed out that a section of DNA which might responsible for olfactory sensitivity was activated in the mice’s sperm. Both the mice and their â€Å"grandchildren† were particularly sensitive to cherry blossom scent and would try their best to avoid this smelling, despite never having experienced cherry blossom in their lives. Another significant change occurs in brain structure. â€Å"The experiences of a parent, even before conceiving, markedly influence both structure and function in the nervous system of subsequent generations, the report concluded.[5] This experiment provides convictive evidence that a traumatic event or a specific environment can affect an individual’s genetics and, by this means, genetic memory will pass on their offspring thus affect their behaviour in the future. This statement probably explains why picky eater avoids particular food. Did you ever resist such kinds of food as ginger, eggplant, celery or garlic since you born? Asking your parents and finding out the possible reasons. This sort of bias is seen as family fear. Descendants sometimes reveal imprints of their ancestor. â€Å"There is absolutely no doubt that what happens to the sperm and egg will affect subsequent generations. Prof Marcus Pembrey, from University College London, â€Å"the findings were highly relevant to phobias, anxiety and post-traumatic stress disordersHe commented: It is high time public health researchers took human transgenerational responses seriously. I suspect we will not understand the rise in neuropsychiatric dis orders or obesity, diabetes and metabolic disruptions generally without taking a multigenerational approach.

Dead Men Do Tell Tales Essay -- William R. Maples Forensic Anthropolog

Dead Men Do Tell Tales In the book, Dead Men Do Tell Tales, by William R. Maples, Ph.D. and Michael Browning, a story is told in how the dead, no matter how dead, still â€Å"talk† to us. The book is appropriately titled because, according to Dr. Maples, truth is discoverable, truth wants to be discovered (2). Dr. Maples tells us of what it is like to be a Forensic Anthropologist. Dr. Maples does not hold anything back in any of his descriptions, from the smell of corpses to the explanations of maggots. Dead Men Do Tell Tales is a complete engrossing journey into the world of Forensic Anthropology and the science of bones. The book is well organized and easy to follow. The story is not from some published medical work containing lengthy medical terminology. The book is best described as the story of Dr. Maples career and interesting encounters it entailed. The book is a total of 292 pages. The book is organized into 16 chapters, each appropriately titled for the subject and stories that it contains. One could only wish that all story tellers could be as good as Dr. Maples. The first chapter, â€Å"Every Day Is Halloween†, gives a preview of the book and talks about the nightmares that he seldom has. â€Å"They are usually flitting images of the everyday things I see on the job: crushed and perforated skulls, lopped-off limbs and severed heads, roasted and dissolving corpses, hanks of human hair and heaps of white bones – all in a day’s work at my office† (1). In this part of the book, we learn of Dr. Maples' life and how it came to include the fascinating world of anthropology. It is in this chapter that Dr. Maples proves his credibility that he knows what he is talking about. He tells of his upbringing with strict moral val... ...anything. I think that the book is so fasinating cause he doesn’t try to put a rated â€Å"R† subject into a â€Å"PG-13† book, after all we live in a rated â€Å"R† world, whether we like it or not. He helps to illustrate his world in all different varieties, I believe that is why the chapters were broken down the way there were. Dr. Maples includes so many fascinating experiences and resolutions to his investigations that even I was able to stay interested to the last page. The class helped out a lot in reading this book because I was able to easily follow his explanations of the skeleton, from differences between male and female skeletons, the different bones that were being talked about, the dental records, and a lot about the skull, like skull features, cranial sutures, and orbital features. I only wish all school books assigned could be as interesting as this one.

Immigrants and The American Dream Essays -- Essays on the American Dre

The "American dream" is different for every person. To some it means financial success, to others it means freedom of expression, while others dream to practice their religion without fear. The "American dream" is a complex concept providing immigrants with the hope of better life. The U.S. government provides the environment and resources for everyone to pursue their dreams. Each year millions of people around the world apply for the Diversity Visa lottery program provided by the U.S. government, however only a few thousand people are lucky enough to come here. America is the place where people are judged by their achievements instead of having references or connections. Even though the American economy is in recession and the achieving of the American Dream is harder, many immigrants still achieve religious, political, financial, and sports dreams here in the U.S. Throughout the history of this nation there are thousands of upon thousands of immigrants coming to this country and achieving the American dream. The Irish immigrated to the United States in 1840 – 1850s in big numbers driven by hunger and by the oppression of the British. Many of them became successful politicians, police officers and businessmen. One of the brightest examples in the history of Irish immigration success is Henry Ford. His grandfather immigrated in the 1840s escaping the potato famine. Henry Ford himself was born in a poor family in Dearborn, Michigan went on to become the most successful car builder in the country (Hennigan). Between 1880 and 1920 the first wave of Italians mainly from South Italy immigrated in the United States (Hendin 13). Many escaped from the poor countryside in Southern Italy to seek better life in America. Shining ex... ...cal Engineering 122.10 (2000): 82. Academic Search Premier. EBSCO. Web. 8 Mar. 2013.

Methods and Consequences: All infusions with high concentration indicated repressive consequence on the growing of M. aeruginosa, and the 0.2-day infusion from rice straw and the 40-day infusion from rye straw indicated the most effectual 1s with EC50 values of 28.0 milligrams C l-1 and 18.9 milligrams C l-1, severally. The extract concentration of rice straw had negative relationship with the maximal growing and growing rate regardless decay continuance, whereas rye straw showed the negative relationship between the extract concentration and the lone maximal growing of M. aeruginosa. Features of infusions through extremist violet optical density should be changed due to debasement of straws. Decisions: Rice and rye straw infusion showed the possibility to command the growing of M. aeruginosa, and nevertheless, might be considered as an facet of another unexpected potency pollutant. Significance and Impact of the Survey: To place most effectual agent against algal growing, extracts from long-run debasement of straws could give more opportunity and possibility to happen allelochemicals. Keywords: long-run infusion, allelopathy, suppression, rice straw, rye straw, SUVA, Microcystis aeruginosaIntroductionTellurian workss have been known to incorporate assorted allelochemicals with anti-algal belongingss ( Rice, 1984 ) . For illustration, barley straw studied comparatively more than other straws like rice and rye has been reported to demo an suppression consequence of algal growing ( Pillinger et al. , 1992 ; Newman and Barrett, 1993 ; Barrett, 1994 ; Everall and Lees, 1996 ; Barrett et al. , 1996 ; Everall and Lees, 1997 ; Cooper et al. , 1997 ) due to assorted compounds extracted from barley straw under many different conditions, for case, oxidized phenolic compounds from lignin beginnings ( Pillinger, 1993 ; Chesson et al. , 1982 ) , p-coumaric and ferulic from cell wall-bound constituents ( Chesson et al. , 1982 ) , and tannic acid ( Hussein, 1982 ) . Rice straw has besides been known to let go of allelochemicals with phenolic compound to restrict the sprouting, gr owing, photosynthesis, respiration and metamorphosis of other workss ( Rice 1984 ; Inderjit et Al. 1995 ; Chung et Al. 2001 ) . Park et Al ( 2006 ) showed interactive and repressive consequence of assorted phenolic compounds extracted from rice straw on the growing of Microcystis aeruginosa. These straw-derived compounds may dwell of legion complex chemicals with assorted features in an aqueous status. As straws would be applied into aquatic ecosystems to command detrimentally algal growing, straw-derived chemicals would be excreted continuously, accumulated or changed into H2O column and features of chemicals would be changed harmonizing to the debasement clip which might be linked with the lability of chemicals. However, there was small information on this relationship between allelochemical production and debasement clip about rice and rye straws. Therefore, our purposes were to analyze whether released chemical from rice and rye straws harmonizing to decomposition clip has different suppression consequence on the growing of cyanobacterium, Microcystis aeruginosa, known as nuisance algae around the universe, and to foretell the alteration of features of extracted stuffs during decomposition clip.Materials and methodsCollection of works stuffsRye straw ( Secale cereale L. ) was collected in Keumsan, South Korea. Rice straw ( Oryza sativa L. ) which was non applied with pesticides to analyze insect pathology was obtained from Kangwon Province Agricultural Research and Extension Service, South Korea. All stuffs were instantly moved to research lab, rinsed several times with tap H2O, dried at 50? for 3 yearss and stored in a dark status at room temperature. Stored workss were cut, mortared, and sieved through 1-mm mesh before experiment.Preparation of short or long-run decomposed infusionsNine gms of each works stuff ( dry weight ) were placed in a 2 L Erlenmeyer flask, incorporating 1.8 L of Moss medium. The composing of Moss medium was ( in milligram ) 16.8 Ca2+ , 5.0 – 10-4 Co2- , 3.0 EDTA, 2.0 – 10-2 Fe3+ , 2.2 K+ , 2.4 Mg2+ , 2.0 – 10-2 Mn2+ , 4.0 – 10-3 Mo6+ , 13.6 Na+ , 6.4 NH4+ , 21.0 NO3- , 0.9 P5+ , 3.3 S6+ , 4.9 Si4+ , 5.0 – 10-3 Zn2+ , 3.3 – 10-8 Cyanocobalamin ( B12 ) , 3.3 – 10-7 d-Bioti n, 3.3 – 10-8 Thiamin-HCl ( B1 ) in 1 L of distilled H2O. To break up straws for a long clip, an aerator provided aerophilic status into the 2 L Erlenmeyer flask because maintaining aerophilic status was of import for the production of phytotoxic chemicals. For illustration, Welch et Al. ( 1990 ) indicated that microbic decomposition of barley straw was critical for the suppression of algal growing, and Newman and Barrett ( 1994 ) suggested that the chief demands for straw to be active are the care of aerophilic conditions and an active and diverse microflora. Humidifier prior to the aerator was installed to forestall the loss of infusions and civilization medium from the vaporization by blow uping dry air. The infusions from rice straw were sampled after 0.2, 10, 50 and 100 yearss from puting straws in the civilization medium and those of rye straw were obtained after 0.2, 5, 15, 40, 50, 100 and 150 yearss from presenting straws. Each subsampling, 200 milliliter of infusions were filtered through a glass fibre filter paper ( Whatman, GF/F ) , and so filtrate was lyophilized and stored in a icebox until Microcystis aeruginosa growing trial. Culture medium including infusions was made by fade outing 20 milligram of lyophilised stuff in 100 milliliter of sterilized Moss medium and filtered through a glass fibre filter paper ( Whatman, GF/F ) . Then, to quantitatively look into the suppression of M. aeruginosa growing by infusions, civilization medium including infusions was diluted with sterilized Moss medium to a scope of concentration of infusions ( test solution ) . Tested concentrations of infusions each decomposition period of straws were in Table 1. The concentrations of dissolved o rganic C ( DOC ) in infusions were determined utilizing the TOC analyser ( TOC-5000A, Shimadzu ) . Each 10 milliliter of civilization medium was stored at 4? to mensurate UV 260nm optical density.Culture status and growing finding of M. aeruginosaEach 4 milliliter of trial solutions was transferred into five glass civilization tubings ( c.a. 11 milliliter, USA Scientific Culture Tube ) with a cap and so, autoclaved. After 1-day chilling, each 0.3 milliliter of M. aeruginosa ( obtained from Institute of Hydrobiology, China ) was inoculated into four tubings and cultured. Remained one civilization tubing was used to mensurate clean value of fluorescence or optical density to observe algal growing each infusion. M. aeruginosa in exponential or stationary growing phase was inoculated for the experiments. Culture tubings were incubated in 25 ±1? and illuminated by fluorescent visible radiations to give about 80? E m-2 s-1 for 24 h every twenty-four hours. Tubes were agitated with a whi rl sociable twice a twenty-four hours. The places of experimental tubings in an brooder were randomized at least four times a hebdomad. In vivo fluorescence of M. aeruginosa was measured with 1 or 2 yearss interval utilizing a spectrofluorophotometer ( RF-1501, Shimadzu ) at 343 nanometer of an excitement wavelength and 680 nanometer of an emanation wavelength. Absorbance ( 680 nm ) of algal cells to mensurate algal growing was determined with 1 or 2 yearss interval utilizing a spectrophotometer ( 101, Hitachi ) alternatively of fluorescence after 50-day infusion of rice straw and 100-day infusion of rye straw.Determination of M. aeruginosa growing and statistics techniquesTo cipher maximal growing ( K ) and growing rate ( u ) of M. aeruginosa, a logistic map was used to show a sigmoid curve for algal growing ( SigmaPlot 9.0, Jandel Scientific ) as follows: EC50 values ( concentration, when 50 % suppression consequence occurs ) were obtained from maximal growing values of each trial compared with control on log-probit graduated tables. A consecutive line linking the two closest values above and below the line matching to 50 % suppression was obtained ( Yamane et al. , 1984 ) . In instance of 50 and 100 yearss in rice straw and 0.2 twenty-four hours in rye straw, EC50 values were calculated by the extrapolation of two closest informations of less than 50 % suppression. To cipher â€Å" no-inhibition upper limit tested concentration † , referred as a maximal concentration shown no-inhibition out of tried concentrations, repeated measured analysis of discrepancy ( ANOVA ) with station hoc of Dunnett trial was used ( p & gt ; 0.05 ) to compare the distribution of optical density or fluorescence for observing M. aeruginosa growing between control without infusion and trial solutions. One-way ANOVA ( station hoc Duncan trial ) was util ized ( p & A ; lt ; 0.05 ) to compare normalized maximal growing or normalized growing rate among three groups of dissolved organic concentration ( DOC ) of infusions, and normalized maximal growing or normalized growing rate are calculated by divided maximal growing or growing rate in trial solution by in control, severally.Ratio of UV260 and DOC in infusionsIn order to foretell the alteration of features of infusions during decaying, the ratio of UV optical density at 260 nanometers and DOC concentration ( SUVA ; specific extremist violet optical density ) was measured. The UV optical density and DOC were measured by a spectrophotometer ( UV-2401PC, Shimadzu ) and TOC analyser ( TOC-5000A, Shimadzu ) , severally.ConsequencesConsequence of infusions of rice and rye straws on M. aeruginosa growing harmonizing to decomposition continuanceEffectss of infusions from rice and rye straws harmonizing to decay periods on M. aeruginosa growing were in Table 1. In rice straw, 0.2-day decay i nfusions showed the highest suppression consequence of the growing of M. aeruginosa among four different decomposition periods and the EC50 value was 28.0 mg C l-1. The infusion of 10-day decay was followed with EC50 value of 30.7 milligrams C l-1. In 50-day and 100-day of decomposition, repressive effects were much less than those in 0.2- and 10-day infusions, and stimulus effects were shown in the scope of less than 23 mg C l-1. Although each period has different concentration of infusions, when no-inhibition maximal concentration was considered in all decomposition periods, 0.2-day and 10-day decay with & A ; lt ; 9 and & A ; lt ; 2 milligram C l-1, severally, could bespeak higher inhibitory possible to command the growing of M. aeruginosa than 50-day and 100-day decay with 23 and 17 milligrams C l-1, severally. Likewise, growing per centum against control at maximal concentration each decay period showed similar form in malice of otherwise maximal concentrations. Overall, repres sive ability was mostly increased in scope of more than approximately 30 milligrams C l-1 in all decay periods ( Figure 1 ) . In rye straw, suppression capableness from 0.2-day decay to 40-day decay increased harmonizing to decay clip through decreasing of EC50 values ( Table 1 ) . Although suppression ability was diminished from 50-day decay infusion, suppression of M. aeruginosa growing increased until 150-day decay. Infusions of 40- and 150-day decay of rye straw had the highest repression capableness with 18.9 and 19.7 milligrams C l-1 of EC50 value, severally. Stimulus or repressive effects on the growing of M. aeruginosa coexisted in similar concentration of infusions from different decomposition clip ( Figure 1 ) . This phenomenon might give equivocal information to construe the repressive consequence by infusions from assorted decay phases. However, it was clear to demo positive relationships between extract concentration and repressive consequence, and perchance to bespeak that different substances from straws might be produced harmonizing to decay periods.Consequence of extract concentrations on the maximal growing and growing rate of M. aeruginosaPercentage of maximal growing ( K ) and growing rate ( u ) of M. aeruginosa in each trial solution normalized by K and u in control was shown in Fig. 2, and three groups were differentiated by merely DOC concentration of infusions irrespective of decay periods ; low ( 2-10 milligram C l-1 ) , medium ( 11-30 milligram C l-1 ) , and high ( & gt ; 30 milligram C l-1 ) DOC. In rice straw, means (  ± SE ) of normalized K and U of M. aeruginosa were 102.5 (  ± 4.9 ) and 96.9 (  ± 2.9 ) in low DOC and 95.0 (  ± 11.1 ) and 102.1 (  ± 5.1 ) in medium DOC, severally, and there was no important difference in K ( p=0.655 ) and u ( p=0.710 ) between low and medium DOC ( one-way ANOVA, n=13 ) . However, agencies (  ± SE ) of normalized K and U in high DOC were 20.4 (  ± 18.5 ) and 43.4 (  ± 21.9 ) , sever ally, and infusions in high DOC might incorporate strong suppression ability against both maximal growing and growing rate of M. aeruginosa. In rye straw, there was important difference in K among three degrees ( one-way ANOVA, F2,25=22.386, P & A ; lt ; 0.001, station hoc Duncan, n=26, P & A ; lt ; 0.005 ) , but no important difference in U among three degrees ( one-way ANOVA, F2,25=0.664, p=0.524 ) . This rye infusion showed repressive consequence on maximal growing but non on growing rate. Means (  ± SE ) of normalized K and u were 106.3 (  ± 6.8 ) and 101.4 (  ± 5.5 ) in low DOC, 67.3 (  ± 8.8 ) and 111.5 (  ± 7.9 ) in medium DOC, and 33.9 (  ± 8.5 ) and 89.9 (  ± 20.6 ) in high DOC, severally.Change of features of infusions harmonizing to decomposition clipSUVA values versus decay periods each infusion were shown in Fig. 3. Those SUVA values were increased harmonizing to decay periods in both straws. It might propose that features of infusion were altering during decomposition of straws, and both infusion could hold different stuffs. Slopes between decay clip and SUVA in rice and rye straw were 0.017 ( R2=0.63, P & gt ; 0.05 ) and 0.019 ( R2=0.93, P & A ; lt ; 0.01 ) , severally.DiscussionThis probe of time-course decomposition in rice and rye straws demonstrated that suppression capacity of infusions on the growing of M. aeruginosa increased with high concentration, whereas low concentration showed no-effect or stimulation for its growing in all decay periods. In rye straw, all infusions after 5-day decay showed higher suppression ( lower EC50 values ) than 0.2-day decay ( Table 1, Fig. 1 ) . Particularly, infusion of 150-day decay along with 40-day had maximal suppressive consequence, and this consequence was similar to the survey of Gibson et Al. ( 1990 ) utilizing barley straw, which indicated that the repressive consequence was produced increasingly during the decomposition of the barley straw and reached a maximal after six months. However, the survey utilizing rice straw showed different forms, where the leachates of short-run decay were more effectual than that of long-run decay although limited factors for comparative experiment between rye and rice straw were existed such as deficit of decay continuance and narrow concentration scope of rice straw. The growing of M. aeruginosa in a bioassay experiment would be inhibited due to the chelation of food by the leachates or straw-secreted antialgal bioactive compounds. The former ground might be ruled out, because there were ample foods and hint elements for the growing of M. aeruginosa in the civilization medium and the stimulation of algal growing in lower concentrations of leachates could non be explained by chelation mechanism. Similarly, one of indispensable growing factors, such as vitamin B12, would be more likely to be produced by straw microflora so removed from solution ( Welch et al. , 1990 ) . For the latter ground, several surveies demonstrated that algal growing inhibited by straw-secreted antialgal substances was associated with the straw decomposition ( Gibson et al. , 1990 ; Pillinger et al. , 1994 ; Ridge and Pillinger, 1996 ) . Ridge and Barrett ( 1992 ) showed that the straw was active even at low concentrations against a scope of algae in natural Waterss including unicellular and filiform green algae and blue-green algae. The difference of lignin content between rye and rice straws could be contributed into different forms of algal suppression when considered that lignin content of rye straw was much more treble than that of rice straw ( lignin content: 21 % in rye straw from Kocheva et al. , 2008 and 7 % in rice straw from Sun et al. , 2000 ) , although we did n't analyse lignin contents of our tried straws. Pillinger et Al. ( 1995 ) showed that lignin-enriched brown-rotted wood is repressive to both Chlorella and Microcystis to a greater extent than lignin-depleted white-rotted wood. As decomposition status in this survey, oxidization of straw may ease lignin solubilization and/or enhance toxicity of the solubilized materal ( Pillinger et al. , 1994 ) . Besid es, lignin appears to be the most promising beginning of compounds like the methoxyphenols ( Ridge et al. , 1995 ) . Methoxyphenols every bit good as quinones, used theoretical accounts for oxidised phenolic compounds, have shown antialgal activity against Microcystis ( Pillinger et al. , 1994 ) . Other phytotoxic compounds such as ferulic, p-coumaric, vanillic, and p-hydroxybenzoic acids were found both in cold-water infusions of the straw of barley, rye, wheat, and in alcoholic infusions of their roots ( Borner, 1960 ) , and in rice straw ( Rice 1984 ; Inderjit et Al. 1995 ; Chung et Al. 2001 ) . The ground demoing otherwise repressive activity during straw debasement would probably be due to the continuum of production, the accretion of stubborn fraction and the chemical transmutation from assorted allelochemicals. As an application of an algae-growth inhibitor, adopted straws would undergo aging, decease, and decomposition in aquatic ecosystem. Under these conditions, plant-induced allelochemicals may be excreted or degraded continuously, be piled up into H2O columns, and besides contribute to the pool of organic affair in the aquatic ecosystem. These plant-derived allelochemicals contribute the formation of humic substances. SUVA can give information about the extent of aromacity of DOM related with humification. Increase of inclines between SUVA and decay periods in tried straws might ensue from the formation of stuffs such as humic substances harmonizing to decay periods and the gradual increasing of fractious fraction instead than labile one ( Fig. 2 ) . Chemical constr uction of straw infusions can be changed during biological and chemical decomposition, i.e. , labile fractions might be much more easy degraded than stubborn 1s ( Fig. 2 ) . For illustration, SUVA, an index of aromatic C content, has been shown to be negatively correlated with biodegradable DOC ( Kalbitz et al. , 2003 ) . However, qualitative designation and each specific consequence on the algal growing from decayed infusions remain to be studied. Although specific chemicals may be needed to be identified for the ecologically and environmentally safe options of Restoration, interactive consequence by combination of several chemicals might be considered ( Park et al. , 2006 ) . Short-run extraction from straws might lose out the opportunity to happen much better option, since this survey showed that infusions were chemically changed due to debasement and changed infusions showed different ability to suppress both maximal growing and growing rate of M. aeruginosa. Conversely, the sig nificantly algicidal chemical might be missed from infusions of low concentration demoing stimulus consequence on M. aeruginosa growing in this survey. Particularly, notable would be the observation to demo the different form about the suppression of maximal growing and growing rate between rice and rye straw infusions ( Fig. 2 ) , and nevertheless, these physiological features might be remained to be elucidated. Although all tested workss showed the suppression of algal growing in this survey, before works leachates incorporating allelochemicals are applied to command algal growing, the addition of the organic affair by leachates in the lakes or reservoirs demands to be considered. The importance of the control of organic affair is beyond difference in the H2O quality direction and research lab consequences should be extrapolated to the field with cautiousness.DecisionAll extracts with high concentration expressed by DOC showed repressive consequence on the growing of M. aeruginosa, and the 40-day infusion from rye straw indicated most effectual 1 with the lowest EC50 value of 18.9 mgC l-1. It was found that the extract concentration of rice straw had negative relationship with the maximal growing and growing rate, whereas rye straw showed negative relationship between the extract concentration and the lone maximal growing of M. aeruginosa. Through UV optical density, features of infusions s hould be changed due to debasement of straws, and this alteration might be linked with their repressive ability on the growing of M. aeruginosa. However, increasing DOC as unexpected pollutants every bit good as extrapolation of research lab plants into field status should be considered anterior to using infusions from straws as an option for Restoration technique.MentionsBarrett, P.R.F. , 1994.
