Résumé

Les auteurs ont étudié 750 bactéries lactiques isolées de vins, en utilisant les tests et le système de classification de Rogosa et Sharpe. Parmi ce grand nombre de souches vingt-trois appartiennent au groupe des bacilles homolactiques et font l'objet du présent travail. Elles se répartissent de la façon suivante: 9 souches de Lactobacillus plantarum. 2 souches de Lactobacillus casei var. casei. 4 souches de Lactobacillus casei var. alactosus et 8 souches de Streptobacterium non classées, différentes des espèces précédentes.

Les auteurs discutent la valcur de cette classification, lorsqu'on se place au point de vue technologique. Ils montrent qu'elle s'applique mal aux bactéries lactiques isolées de milieux fermentés acides comme le vin. Elle a peu d'intérêt pratique, car elle ne permet pas de repérer une souche et de prévoir par sa position systématique les constituants du vin que cette souche est susceptible de métaboliser.

A study of some homofermentative lactic acid bacteria isolated from wines Summary

The authors have studied 750 strains of lactic acid bacteria isolated from wines. In this study the test and classification of Rogosa and Sharpe were used. Of the strains mentioned 23 belonged to the homolactie bacteria, including 9 strains of Lactobacillus plantarum. 2 strains of Lactobacillus casei var. casei. 4 strains of Lactobacillus casei var. alactosus. and 8 strains of a non-identified Streptobacterium species.

The authors discuss the value of the classification mentioned from the point of view of wine technology. They conclude that it cannot be applied in the case of lactic acid bacteria isolated from acid fermentation products such as wine. It is only of little practical interest because it does not render the identification of the strains possible, nor does it permit a prediction of the wine constituents which the strains concerned are able to metabolize.

Do you agree that attending a live performance is more enjoyable than watching the same event on TV?

When television was invented some people predicted that live performances would disappear forever but they still attract large audiences. Indeed, many people believe attending a live performance to be much more fascinating than watching the same event on TV. I support this point of view for a number of reasons.
Firstly, live performances appear to be increasing in popularity due to some social element involved in going, for example, to the theatre or to the opera. As a rule, people regard it as a special occasion, prepare for it in advance and look forward to it. Secondly, the key to success of a live performance is in its effect on the audience. Actually, it offers people quite a unique experience. A live performance may often be so realistic and exciting that, being enchanted and deeply involved in the action, people simply forget where they are. The effect is usually enhanced by the fact that every viewer forms a part of an audience and shares excitement with a lot of other people.
It might be argued, however, that one cannot go out every night and TV serves its own purpose: it is cheaper, more available and more convenient. Besides, television can also offer good films and interesting programmes. Nevertheless, in my view, these are only trivial impressions when compared to the magic of a live performance.
All things considered, I must conclude that while television remains to be mass entertainment, a live performance can offer people a real treat. Thus, it appears to be much more enjoyable. (270 words)

Socialism, as conceptualized by the classical Marxists refers to an economic system governed by social and collective ownership of the production machinery where workers democratically control economic resources as well as economic decisions (Hunt, and Sherman, 1990). The system is characterized by society-wide planning that helps in coordinating economic decisions at all levels putting emphasis on democratic ideals in determining the criteria of economic rationality (Yates, 2003). Capitalism, just like socialism, utilizes the willpower of the people, whose actions in a free market free from interventionists’ policies foment economic activity that is gainful to all. The system is based on the assumptions that individual operations within the economy are driven by self-interest that ultimately helps them and propel the wheels of the economy towards prosperity (Schweickart, 2002). Built on the premise of combined processes of national liberation and industrialization, the promises of more equality and increased well being was evident on the intentions of both systems. The ideas of Marxist or capitalist societies are very alluring. The notion of everyone being equal, even if it means forcefully taking from the rich to give to the poor seems to serve justice in every sense. However, the defects of both systems have ended up creating states of fear, exploitative society due greed resulting in a worse off state of affairs where inequality reigns supreme.

The systems as envisage by the core founders were dependent upon types of human characteristics that is hard to come by. The success of socialism was pegged on very little greed and jealousy among individuals. Apart from the foregoing, people must possess general philanthropic feelings and a willingness to work as hard they can for everyone else good. In the system, those with the greatest abilities and working the hardest must be satisfied with rewards that are equal to those with lesser abilities and not working hard or not working at all, which is very unlikely and unthinkable in the current society set-ups. Marxism ideals undoubtedly lead to free riding and slacking, which is rather unacceptable. The economic defense of a capitalist state engenders an impressive pedigree. From Adam Smith's perspective put in writing published in “Wealth of Nations,” the argument that a free-market economy increases the living standards of many at a much faster rate than a socialist economy closely monitored under the command of the state is appealing to some extents.

Why haven’t the systems delivered the promise of well being to all? Under socialism, the idea of incentives playing a critical role in informing market economics was ignored totally. Even though the soviet socialist republic deviated from state control of markets, creating some space for market forces, the economy was still largely centrally planned. Private property was still largely in the hands of the state. In effect, soviet socialism became a system without effective incentive mechanisms that could direct economic activities. The pricing system, though not appreciated by many is a fundamental aspect of the economy. A legitimate source transmits information concerning relative scarcity of commodities but coordinates proper functioning of economic activities. Price controls fixed by authorities oftentimes transmit misleading information on scarcity of goods and services. Socialism also failed due its failure to integrate profit loss accounting within its structural framework. The allure for profits effectively monitors economic performance by constantly evaluating business enterprises. Under central planning, Soviet socialism failed to determine programs that were useful and deserved to be expanded and those that were making losses that therefore had no moral justification of existing. The fatal defect that completely led to the failure of socialists’ ideals was the complete disregard of property rights. Publicly owned assets lacked the incentive of wise stewardship. Responsible use of property is completely absent and abandoned (Yates, 2003). In one of his books, Howard Sherman viewed the Soviet model as socialist, referring to the system as that in which the means of production are largely owned by the state (Sherman, 1972). In his release of 1987, Sherman decried the lack of popular control over the economy arguing that the Soviet model was full of flaw. The system lacked democratic ideals to which Sherman argue was a fundamental aspect of system they sought to create. He argued that economic democracy was not only desirable for soviet socialism but also essential to the system (Sherman, 1987, p. 260).

The Soviet economic model is the only system of socialism that gave birth to an alternative system to that of capitalism. The Soviets developed their system in the late 1920s and early 1930s (Sherman, 1972). Referred to as state socialism, the system was later introduced with variations in many countries of Eastern Europe, China, among other countries, Africa taking a share of the system (Zimbalist, Sherman, and Brown, 1989). That model of socialism were dismantled or rapidly retreated everywhere it had been adopted. The attempt to restore the Soviet state socialism under the guidance of Mikhail Gorbachev between the year1985 to 1991 led to the complete demise of the system and the subsequent disintegration of the Soviet state. The leadership of the successor states after the collapse of the former Soviet Union never looked back in building capitalist systems (Kullberg, 1994).

As explained by William Thomson in his rejection of the capitalist market concepts backed liberal ideals, individual pursuit of wealth encouraged by self interest is not only chaotic but creates five evils; all of which stems from the principle of competition (Yates, 2003). First, idea of market socialism fronted in capitalistic markets creates rivals rather friendly competitors as envisaged. Secondly, the system ended up creating the oppression of women. Within an individual family, the little domestic drudgery was left under the care of women. Third, was the anarchy of the market; as long as the concept of free will was to eliminate the capriciousness tastes of capitalists, the system remained a source of crises and depressions causing economic instability, massive unemployment through cost cutting machinery, wastes, and the general social suffering (see Hartmann, 2002). The wars caused the search for resources to replenish economies today serve to reinforce the real devil in capitalistic ideals (Heinberg, 2005). Fourth, the system has not only been a recipe of malfunction and numerous accidents to human life. Lastly, due competition, the system has concealed the dissemination of knowledge, making its acquisition primary based on personal gain and greed (Scherf, 1999). What is new is inaccessible to competitors.

Indeed, capitalism and socialism has ended up creating unequal society. In the United States, the poor are in constant dreams of hitting jackpots than creating a society of equals. Capitalism is relentless in its assaults of the common person. Television programs are full of commercials that do urge to buy or sell. The ideology of capitalism is ubiquitous and cannot be avoided. Its stunting features are everywhere (Yates, 2003).

Classification Essay Topics

Classification Essay Topics

The principle you apply to classify any given topic is the most important in an essay of classification. Another thing you need to keep in mind is what you choose as this will form the basis of your essay. Though there are many creative college essay topics, not all can be considered for a classification essay. For example, "famous strategies in world politics" is a very interesting topic, but if you have to write a classification essay on this topic, it just won't be possible. You might be able to classify it on the basis of the political type, but that doesn't give you much to write on. On the other hand, you can take something as simple as "music in my music player" and do some unique classification of the same. In this article, we will first see what exactly is a classification essay and then look at some diverse essay topic ideas that might help you.

What is a Classification Essay?

A classification essay is written to basically judge whether the students are capable of understanding a set of subjects and then classifying them based on a rational principle. The most important thing in this kind of essay writing is to determine the rational principle or scheme. Each topic will contain a lot of things that need to be divided into groups. You have to analyze all the given data. After this, figure out how they can be classified depending on different parameters. Pick the most rational and reasonable out of them all. The end result will be the category or groups you make. A classification essay might also demand ratings from you. It might ask you to evaluate a particular group of things and rate them. You will have to decide the parameters for this rating, which should be done by giving proper and true information.

List of Topics
  1. Classify different inventions on the basis of their importance to mankind.
  2. Evaluate the different types of literature .
  3. Classify major historical moments in chronological order.
  4. Evaluate the different types of political parties.
  5. Classify different types of rocks based on formation.
  6. Evaluate all the libraries in your neighborhood and rate them.
  7. Classify the different songs you have in your iPod.
  8. Evaluate five music downloading websites and rate them.
  9. Classify the different types of bankruptcy.
  10. Evaluate and classify a few colleges in your city.
  11. Classify the movies you like the most according to their theme.
  12. Evaluate a few clubs in your area and rate them on self-formed principles.
  13. Classify different types of doctors and what they do.
  14. Evaluate the different coffee shops in your neighborhood and rate them.
  15. Classify different types of snakes based on if they are venomous or not.
  16. Classify different types of bank accounts .
  17. Evaluate the last 3 books you read and rate them according to your preference.
  18. Classify different types of plants .
  19. Evaluate 5 different indoor tanning lotions.
  20. Classify taxes depending on individuals and businesses.
  21. Evaluate the top selling companies of denims.
  22. Classify all the books you have at your home.
  23. Evaluate your performance in school since Grade I.
  24. Classify different types of love.
Now that you know all these easy classification essay topics, choose any one that you like. In these essays, how you classify is more important than what you write. The principle or scheme you choose to classify holds the most importance. Don't make too many categories, but don't make just two categories either. The entire meaning will be lost then. You can have a look at some classification essay examples and get your views cleared.

Classification Essay Writing

Classification Essay Writing

By Julia R. April 27, 2007

Not a lot of students know for sure how a good classification essay can be written. But once they start surfing the Internet in order to find help on essay writing, they locate several sources that offer different and sometimes incomplete information on the same topic. We’ve analyzed and studied all the resources, and now we offer you a complete list of custom essay writing guidelines plus professional advice on writing a custom classification essay from our experts.

1. Writing a Classification Essay. The Outline

In custom classification essays. a writer organizes things into categories. The classification essay organizes supporting details into three or more groups with each group having its own identifying characteristics.

When one of the classification essay topics is chosen, your following steps are:

– sorting things into useful categories;
– making sure all the categories follow a single organizing principle;
– giving examples that fit into each category.

  • Classification essays that offer an endless number of classes are very confusing. Make sure you revised your draft and got rid of unimportant categories. This way your essay writing will be free from such abstract words as “miscellaneous” or “others.”
  • When making an outline, choose only one principle by which you are going to classify your subjects.
2. Writing a Classification Essay. Elements of Essay Writing

A classification essay is formed by elements.

There are three important elements to custom classification essay writing:

– Set. Any set, which is to be classified, must share a common characteristic or be able to be distinguished from things outside the set.
– Scheme – the quality, standard, type, or function by which the elements of the set are sorted into classes, that is, the principle of selection for creating the groups.
– Classes. In general, when writing about each class, begin with an explanation of the descriptor, the characteristic which identifies the members of one class and differentiates the members of that class from the members of another class. Then include representative examples of the class.

Our tips on essay writing:

  • Often, a discussion of the class also includes an evaluation of the worth of this class.
3. Writing a Classification Essay. The Introduction

The Introduction states the thesis of your essay writing topic .

The Introduction of a classification essay is quite straightforward. In the thesis statement. you mention that there are several types of investigated subjects according to their properties. Pay attention to what you are writing because you can accidentally leave out important categories.

Our tips on essay writing:

  • There has to be a specific reason for writing a classification essay. Make it look interesting. Unexpected classifications of ordinary things are a great way to attract attention.
4. Writing a Classification Essay. Writing Development Paragraphs

The developmental paragraphs define each type you mentioned in the thesis.

The organizing principle is how you sort the groups. Do not allow a different principle to pop up unexpectedly. Here’s how you should organize your paragraphs:

– investigate only one category per paragraph;
– write approximately the same amount for each class. Give equal importance to each segment of the classification;
– move from least to most important, and vice versa;
– you can also go from small to big categories.

Our tips on essay writing:

  • Sometimes it is a good idea to show similarities, or differences between investigated categories.
  • Use transition sentences to make a neat switch between categories.
5. Writing a Classification Essay. The Conclusion

A conclusion gives you an opportunity to summarize the results and prove or deny the thesis statement.
