Econ 336 - Essay Example However, India was observed to be amid the leading countries to plan a population check but it still failed to attain its objective. The government policies with regard to controlling population have been assessed to be a prime reason behind the success of China and the failure of India. This research paper aims at highlighting the differences in the population policies of both the nations in order to gain a lucid comprehension regarding this definite aspect. Table of Contents Abstract 2 Table of Contents 3 Introduction 4 Literature Review 5 Comparison of the Government Policies of India and China 6 Method of Analysis 9 Analysis 9 Conclusion 12 References 13 Introduction India and China have been identified to be the two countries with the highest population along with their respective cultures being as old as thousand years. Both the countries were regarded as young nations in spite of the huge changes related to death as well as birth rates that the nations were undergoing. This pa rticular aspect is believed to hold serious significance in the present history of demographics. The pace of rise in the overall population of the world has been found to gather speed notably during the previous century. The increasing pace of rising population makes it important to comprehend the various aspects manipulating the population development and the consequences that the growth related to population can have and the way governments need to manage their respective population. As mentioned earlier, China has been measured to have the highest population but the rapid rise in terms of rate related to population in India proposes that it would soon surpass the population of China. It needs to be mentioned in this respect that growth is associated with several ways towards the alterations in the population. The endeavors of the nations especially by India towards development can be stated to have triggered the population growth. Therefore, it has been correctly mentioned that t he rise in population was set free with the help of trimming down the rate of mortality and even migration (Coale, 1983). Literature Review India as well as China have been measured to be the two countries across the world that records population above 1 million. Although the population of China has been gauged to be greater than India, but it has similarly been predicted in this context that the population count in India is supposed to exceed the level of China by the year 2025. There have been witnessed a rapid rise in the population rate which has attributed to the factor of higher birth rates in comparison to the death rates. A desire in the family sizes in India was recorded owing to the economic worth associated with children which has also been a contributing factor for the population rise. It has been stated in this regard that devotion towards children or rather the desire for children in the family is perceived by the Indian families to be a kind of intergenerational shift as children are regarded as significant inputs with regard to the production function in relation to the households which is considered to be competent of generating extra household income (Portner, 2001; Dasgupta, 1995; Cochrane, 1975), emotional incentives (Stecklov, 1997; Weil, 1994) and security in the old age (Ehrlich & Lui, 1991). Children are also predicted to entail the competence of acting as a form of insurance in opposition to the deficits in terms of income

Advantage and Disadvantages of Japanese Nationals Working in the Philippines Essay Example for Free

Advantage and Disadvantages of Japanese Nationals Working in the Philippines Essay â€Å"Teaching is learning. Teaching is enriching. Teaching is challenging, it’s trying in unimaginable ways. Teaching is motivating, it’s inspiring. Teaching is frustrating, it’s frightening. Teaching is growing. Teaching is loving. Teaching is a blessing. And being a teacher means that I have a lot to learn.† (anjaligill, 2011) A quote I have read on one article on the internet that actually touched my heart. I am not a teacher but appreciate the hardships of teachers throughout their journey to imparting to us student all they can for us to have a better future. Yes we have a lot of teachers here in our country but learning is not limited to only our country. Because of media and many other sources or information we have been exposed to other cultures and languages from many different countries. Thus which lead to us wanting to learn other culture and languages. Some of these languages are Korean, Japanese, Spanish, and French. And who else are more capable in teaching us these languages than the natives of theses languages themselves. That is why this study aims to shed a light on the existence of Japanese Language teachers that are working in the country. The first part of this paper is going to touch upon the rules that’s the immigration imposes on these aliens that wish to enter the country. What kind of permits and visas that must be secured in order to be able to work. Also it talks about the role of the Department Of Labor and Employment (DOLE) in allowing these aliens to have a fair and legal job here. The second part of my report talks about the different issues that these aliens have encountered over their years of working in the Philippines. For years now we have been hearing about the melodramatic life of an OFW, we’ve had a lot of articles on the different experience they have out there. But have we ever given a thought about these foreigners that come to our country not as tourist, but to look for jobs? Probably as teachers? What more these Japanese nationals working in Davao as Japanese language teachers? We’ve been so focused on Filipinos that we forget to check on these other people who are also making a living here in our country. This paper will try to shed a light on what are the most common difficulties and what are the measures they took in order to be able to overcome these obstacles. And I am hoping to gather these datas through interviewing some Japanese nationals residing in the country specially Davao. A. What are the necessary visa and permits these Japanese nationals must secure in order to be able to work in the country? B. Are they given enough compensation and benefits in their jobs? C. Why of all other country would they choose Philippines? D. What are the different experiences they have here? For the last part this paper will try to compile the gathered data and express what are the common advantages and disadvantages of experienced by these Japanese Language teachers working in the Philippines? Those are just some of a few things this study aims to shed a light on, and to give the readers a deeper understanding on their situation through their experiences. Review of Related Literature 1. Japanese Language as a Profession When we hear the word Japanese Language most of us would think: oh that’s all about kanji!† â€Å"That is a very hard language to learn†. Yes it is true, it is not an easy language to learn but it is also one of the most interesting of all. With all the variations in the conjugation of every word, to all the particles for every sentence, but most especially to the different strokes in their unique 3 writing styles namely hiragana katakana and kanji. In the beginning yeah it will be hard but in the long run you will be able to appreciate all the hardships you have gone through in order to reach that level. So because of that many people have engaged in learning the language. Some would say that if you really want to learn something you have to do it yourself. But then again because of the complexity of this language it has become hard for others. That is why we have come to the conclusion that who else is more capable to teach us the complicated and very meticulous language than these Japanese nationals themselves? But then again this poses a very big hindrance when it comes to language barriers. It is because before Japan has been a very secluded country that doesn’t want to open up to other country. That’s is why even though some Japanese wanted to teach Japanese it would be hard for them since that not all Japanese know English and since English is the universal language communication and explanation would be hard. But as years pass by and as Japan slowly open their doors to other countries, international colleges started to rise and because of this the Japanese nationals studying in such colleges are being exposed to the word and thus they became aware of the eagerness of other people to learn their language which triggered a domino effect to theses Japanese to teach them. 2. Philippine and Japan relation in terms of work Over the years the Philippines was known by the world as major exporter of skilled workers. They even have this saying that there is no country in the world that does not have Filipinos in it. From that this study aims to focus on the Japanese citizens working in the country. For decades there has been a noticeable relationship between Japan and the Philippines. May it be in terms of trading of goods, and even official development assistance funds also known as the (ODA). The relationship of these two countries not only varies in goods and monetary sector but even in human resources. The Philippines is reputed to be the leading exporter of labor in the world, ranging from the semi-skilled to professional and technical workers (CORTEZ, 2009). This greatly impacted on the yearly remittances that the OFW’s give to the country. At the same time Japanese engineers, managers, experts and other skilled workers have entered the Philippines to accompany, implement and manage the huge direct investments and overseas development assistance programs of Japan (Tereso S. Tullao, Jr. and Michael Angelo A. Cortez, 2004). The Japanese have remained the largest group of foreign workers in the country over the years (OECD 2001). This then greatly impacted the country in terms of tourism. 3. Naturals working overseas Due to the growing economic crisis in the world most people opt to work in other country to look for â€Å"greener pastures†. Approximately eight million Filipinos are overseas, representing almost ten percent of the nation’s population (Commission on Filipinos Overseas, 2004). And one good example to these is the growing migration rate in the Philippines. Where in most Filipinos think that because of the economic crisis in the Philippines and the Low salary that working overseas became a better option. Yes they may have big salaries and they may be able to experience other culture but at the end of the day these OFW’s would have to sacrifice being with their family for money. 4. Language Barriers In order to be able to teach students, communication is important and in communication Language is vital. This is what makes learning easy. Because through language student will be able to understand what the teacher wants to deliver. But in teaching language something these language barriers pose a very big problem. Especially for those language teachers who are native speakers of the language they are teaching and only know a little English. English, with its many varieties, is a language of international and therefore intercultural communication. (Sharifian, 2009). But then we all know that there are still some countries that are not open to accepting English as an international language and Japan is one of them. The people being raised to love their own country in other words in the ways of patriotism it became hard for them to open up an accept changes being brought by the modern world. Definition of terms 1) (AEP) Alien Employment Permit is a document issued by the Department of Labor and Employment which authorizes a foreign national to work in the Philippines. 2) Alien shall refer to the foreign nationals who intend to work in the country. Japanese Workers I. Immigration All foreign nationals can freely enter the Philippines with only a passport and other travel documents for business, leisure, and social visits. The Philippine Immigration Act of 1940 states Foreigners or â€Å"non-quota immigrants† may be admitted without considering such numerical limitations (CASTRO, August). The country has not been strict on allowing foreigners to enter, In fact Nationals from some countries are allowed to enter the Philippines without visas for a stay not exceeding twenty-one (21) days, provided they hold valid tickets for their return journey to port of origin or next port of destination (Bureau of Immigration 2007-2008), Japan being one of these countries are allowed to enter the country without visa. They must present for admission into the Philippines unexpired passports or official documents in the nature of passports issued by the governments of the countries to which they owe allegiance or other travel documents showing their origin and identity. II. Department Of Labor and Employment (DOLE) But when it comes to employment the Philippines is very strict at letting foreigners to work in the country. These aliens need to secure certain visas and permits before they can actually work here. Some of these are the a)Alien Employment Permit (AEP), b)Special Work permit, and the c)9g Prearranged Employment Visa. a) Alien Employment Permit (AEP) is a document issued by the Department of Labor and Employment which authorizes a foreign national to work in the Philippines. This permit must be petitioned by a company to allow a foreigner to work locally and is the requirement for a 9g visa as well as several other visas. The employment permit may be issued to a non-resident alien or to the applicant employer after a determination of the non-availability of a person in the Philippines who is competent, able and willing at the time of application to perform the services for which the alien is desired (Labor Code of the Philippines PD 442, Article 40). Article 41 of the Labor Code provides: â€Å"After the issuance of employment permit, the alien shall not transfer to another job or change his employer without prior approval of Secretary of Labor and Employment.† In addition the alien who is found to be working without an AEP or an expired AEP shall pay a fine of Ten Thousand Pesos (P10,000) for every year to the Regional Director (DOLE Department Order No. 75-06 (Series of 2006)) and shall be subject to deportation after service of his sentence (Ferrolino, 2009). b) Special Work Permit is given by employers to foreigners that will only work for a brief time in the Philippines usually less than 6 months that can be extended for another 6 months and they are not required to apply for a (AEP) from DOLE ( Triple i Consulting Inc., 2005). c) 9g Prearranged Employment Visa is given to any foreign national who will be employed in the Philippines and occupying a technical, executive, managerial or a highly confidential position in a company for at least one year, can apply for an employment visa under Sec. 9(g) of the Philippine Immigration Act. III. Issues/Problems 1) What are the necessary visa and permits these Japanese nationals must secure in order to be able to work in the country? As to the rules of immigration and DOLE these Japanese nationals knowing that they are considered as aliens must be able secure an AEP before they can work. But according to one of my respondents who is ms. Ariza Okumura, that she only secured a working visa which is valid for only two years, before she got to work in our school. 2) Are they given enough compensation and benefits in their jobs? When it comes to compensations and benefits we all know that Philippines really give a very low compensation rate in terms of salary. According to the National Wages and Productivity Commission minimum wage in the National Capital Region ranges from P456.00 to P419.00 depending on the type of job, while in Davao city it ranges from P301.00 to P270.00. Clearly this kind of wages will not be enough to support a family that is why these families that are working here in Davao always keep a tight budget on their money. According to Miss Ariza Okumura, a Japanese Language teacher in Mindanao Kokusai Daigaku â€Å"if I live for a long time for example ten (10) years or more? The salary is okay. But if if have plan of one year or three years? The salary is low.† Mr. Tanino also a Japanese Language Teacher in MKD said â€Å"the salary is low†. True enough even these aliens or Japanese nationals to be exact who is working here in the Philippines have also experienced the very low salary here. In another interview I conducted this time it is from Takako Okamoto, also a Japanese language teacher in MKD she said â€Å"I think it is enough, for Japanese nationals’ teacher†. From this we can see the different points of view of these Japanese in terms of the compensation given to them. But one thing is for sure, they do not want the money, it’s their love of teaching and imparting what they know to those who are willing to learn. 3) Why of all other country would they choose Philippines? Some would say that Philippines is a good place to relax because of its serene beauty and it is also close to nature because it is rich in natural resources. The country being an archipelago means it is close to beaches which attracts tourist from all over the world to come here. A few would even say they want to go to the Philippines because of Filipinos have been known to the world as hospitable kind of people. But when it comes to employment there have been also very many speculations upon the capacity of the country to cater workers because of the ongoing crisis in its economy and a whole lot more. But even so after all these negative comments and speculations some still chose to work here. One good example is Ariza Okumura, MKD teacher she said during our interview that it was here choice to work here and when I asked her why this is what she told me â€Å"before when I was student we had a school trip and I came here in Davao. Also I really want to teach Japanese in foreign country†. Almost all of the Japanese language teachers I have interviewed said the same thing. That it was in their own will to go to the Philippines. In a follow up question I had which was â€Å"did you originally come here as a teacher?† I was amazed at their answers. Takako Okamoto, a MKD teacher said â€Å"I chose Philippines as a place for volunteer work.† Tanino, who is also a MKD teacher, said he first came to the Philippines to work for a company named sharp. From their answers it was clear that teaching was not their real objective in coming here, but the longer they stayed the more they fell in love with the country and its people. â€Å"During the time I met many Filipino Filipina and then they took care of me well and then I don’t like to forget everything they did for me. After one year four months I came back to Japan and decided to help the Filipino resident in the Philippines as Japanese Language teacher.† Said Okamoto sensei. 4) What are the different experiences they have here? We can finish up all day if we talk about experiences, but these are one of the parts of the lives of the people which make us actually say that we are alive. Through these experiences we learn and from these learning we can adjust in order to make things better. When it was time to ask them this question I observed that they had a very hard time in picking which experience they wanted to share. One of them said that being with students everyday are counted as one of their memorable experience, one also said that seeing the students learning is their most unforgettable experience. But there is one story that actually touched my heart. It was from Takako Okamoto she told me â€Å"actually he’s a last year graduator. He hated any kind of teacher, he hated study Japanese especially. He was lazy to attend all the class he was lazy to pass shukudai (assignments), and then sometimes he was against to the teachers. But I have been continuing to approach to him. Siguro very Samok sa kanya *how about your shukudai ? *how many times absent you might be dropped! Like that. Whenever I see him I say something. Finally he changed, he changed totally. He had a focus on study in nihongo but it was already 4th year. But I found his changes. Before RP Japan I was telling him, I know you are good at nihongo. You try to attend speech contest in RP Japan. In his speech he was saying to me thank you, like saying because of me he was changed. But for one week he got dengue and was absent. Nobody expected he could attend the speech. But he came, and said *Sensei I’m Here.† It may not mean as much to you but as I saw her as she was telling me this story you would see the happiness in her eyes. The kind of happiness that meant showed how their job as a teacher can be very rewarding, that even the small thing could make a big difference. Conclusion I admit I started late in doing this paper. But in those limited amount of time left, I was still able to learn new things through this. First is the importance of time. Know this is not port of my paper but I was able to learn and appreciate time, and how to use it wisely and productively. Second is the importance of work, as to why people look for jobs. Another is I learned to appreciate the teachers more. This happened during the times I was able to interview a few of them. At first I was hesitant in conducting interviews because I was afraid of the teachers, but then I said to myself â€Å"what’s there to lose?† So when I started the interviews I realized that I should not be afraid of these teachers because their only goal it to teach is to become a better person. That they are doing what they do not to make us suffer but to make us learn, I was able to see that â€Å"the students are the only ones who are making themselves suffer†. I also came to a conclusion that in all we do there’s a good and bad side to it. Isaac Newton’s third law of motion said that â€Å"For every action, there is an equal and opposite reaction†. In life that is also proven true, with everything we do, even in may it be as a person, as an employee, etc. there will always be an advantage and a disadvantage. Yes Japanese language is very interesting but at the same time it is also very complicated and hard to learn. Even the Japanese Language teachers themselves said that its hard and it really takes time. That even they as a teacher they also have to adjust to their approach to the students. Which brings us to the conclusion that teaching as a language teacher is not just a profession but also a lifestyle, where in it has its up and downs, the good and the bad, and its own advantages and disadvantages.

Synthesis of a New Potential Herbicide

Synthesis of a New Potential Herbicide CHAPTER 1 INTRODUCTION Background of Study Since the beginning of the world, every creature in the world consumes food in order to survive. They ingest creatures in the sea, animals on the ground, or even vegetables on the land. In the olden days, the vegetables that mankind intake is without adding of synthetic chemicals or in other words it is organic. The purpose of adding chemicals during the vegetation process in this era of modernisation is to overcome undesirable situation like remove unwanted plants and eliminating pest. These chemical is known as pesticides. Pesticide is defined as chemical used for plant suicide. Generally, pesticide can be separate into four categories. There are insecticide, herbicide, fungicide and bactericides. Pesticides have cause pollution to the environment. It also has an impact towards animals, plant and mankind. Pesticide is a type of persistent organic pollutant to the environment because it is hard to degrade. The physical properties have disallowed degradation to occur. Examples of pesticide are paraquat, diquat, and DDT (Hafiza, 2014). In order to produce food in high yield, weed control is used. It is to ensure the food produce is economical beneficiary. The most common weed control used is by the use of herbicide. It was because herbicide is easy to use and it is efficient (Lodovichi et. al., 2013; Pannell et al.,2004; Parsons et al., 2009). Herbicide can be categorised. Normally herbicide is categorised based on mode of action. The herbicide normally work based on inhibition of enzyme or inhibit mitosis to occur (Fujiwara, 2014). Mankind need to produce more food. It was because the world population will rise to 9.6 billion people (Fujiwara, 2014). The food mankind need is going to increase since everyone need food. Yet, there are still famine going on in this era of millennium. Just in Africa alone there are more than 18,000 people are starving. Just because of food shortage, most of the children die before them reaching at the age of 5 (Missionaries of Africa, n.d). The need of food have cause human to use herbicide extensively. The extensive use of a single herbicide had cause the weed in the field to be herbicide resistant. Herbicide resistant in weed will cause several implications. It will cause the need to change a brand new weed and crop management system, cost ineffective in weed management, reduce in herbicide choice and low productivity of crop (WSSA, 2011). Thus, mankind need to produce more food for the generation to come. Yet, a cheaper pesticide is need for weed control. However, the used of pesticide can alter the gene of weed and it will resist toward the herbicide and a new herbicide is needed. The scope of study is synthesis a herbicide. The herbicide is a derivative from benzaldehyde, cyclohexanone and phenyl hydrazine. The synthesis of the derivatives it will then be test with thin layer chromatography (TLC). After, it will separate by using a silica column. Then, it is tested with nuclear magnetic resonance (NMR) to structural confirmation. At last but not the least, the synthesised structure is subjected to herbicide bioassay test. Significant of Study The significant of the study is to synthesis a new potential herbicide. The synthesis of the potential herbicide is to allow a new herbicide to be accomplished in the market with new mode of action. The last invention of herbicide is at 1980’s (WSSA, 2011). Most of the researchers have ford see the future and synthesis a lot of brand new technology in a lot of area. However, the urgent development of a new herbicide to enhance food productivity and quality had been a concern. Herbicide resistant had been a serious matter to the world as it will affect food productivity. In nationwide, there are approximately 80% of herbicide resistant crop due to extensively use of a single type of herbicide. In side of these 80% herbicide resistant crop there are more than 90% were glyphosate resistant while the remaining percentages glufosinate resistant (Duke,2014). Thus, the urge of synthesis a new herbicide is needed to allow more choice of herbicide. In a conclusion, the need to develop a new herbicide is needed. It is to overcome the problem of increasing need of food, to resolve famine in Africa and improve food quality. Objective of Study The Objective of study is as below: To synthesised benzyldehyde, cyclohexanone, and phenyl hydrazine derivatives as potential herbicide To develop a new herbicide to resolve the problem of herbicide resistant To characterise benzyldehyde, cyclohexanone and phenyl hydrazine derivatives To overcome the problem of herbicide resistance CHAPTER 2 LITERATURE REVIEW 2.1 Pesticide Human have the greatest mind of all among animal range from bacteria to the largest animal in the world. Human is creative. Mankind likes to solve problem. When there is a problem mankind tends to find out the ways to resolve the problems. As an example, there is a species of pest in the house and human use pesticide to eliminate it. Pesticide is not something trendy in this era. It have been used since century ago and the animal that mankind label as pest can be kill by using pesticide. The history of pesticide can ancient Romans lived. In that era of time, sulfur is burned to eliminate insect pest and weed is controlled by using salt. Later at the 16th century, the ant which mankind label as pest is killed by using the mixture honey and arsenic mixture. In the 16 century also, the Chinese uses nicotine to control plum curculio(Hassall, 1990). Then, human in the 19th century try to develop an effective pesticide. To control pest the farmer in the field in that century used sulphur, copper acetoarsenite, nicotine sulphate and calcium arsenate as pesticide. However, the effects are not that effective (John, 2010). There a lot of chemicals was introduce at post-world war II. The chemicals included BHC, aldrin, endrin, dieldrin, DDT, and 2,4 D (Muir, 2012). These chemicals use widely in that era. DDT is used as pesticide because of cheap, high effective and low toxicology (John, 2010). Where 2,4-D(agent orange) is being used as a herbicide due to inexpensive, high effective and easy to apply. However, pesticide have cost a lot of problem nationwide. During the world war II America used this herbicide, agent orange to attack Vietnam. In 1960’s, there is a book named slient spring whom author name Racheal Carson have raise the awerenes toward the usage of herbicide. In the book of silent spring, the author explains the bioconcentration, bioaccumulation and biomagnifications through the food chain. Pesticide can be categorized into many categories. These included acaricide, antimicrobial, attractant, avicide, fungicide, herbicide, insecticide, molluscicide, nematicide, piscicide, repellent, redenticide, and synergist. Different type of herbicide will target different type of pest group (Delaplane, 1996). Diagram 1, Types of pesticide and it’s target group. Adopted from, Delaplane, K.S. in pesticide usage in the united states: history, benefits, risks and trends The usage of pesticide is wide. It can be use in agriculture, public health, industry, household, personal application and material building. Usage of pesticide in India Diagram 2, usage of pesticide in India Adopt from, Gupta, P.K.(2004), Pesticide Exposure- Indian scene 2.1.1 Role of Pesticide in Agiculture The widely used of pesticide has cause some benefits to the nation as well as world. It was because the crop production annually will drop when pesticide is not used. One research had been done that when pesticide is ban, the crop production in United State alone will drop 73 percent. The decreasing in the crop production of groundnuts, cotton and soybeans will lead to instability of crop. At the same time, the decrease in crop production will affect the price of food and the famine in the world will increase (Delaplane, 1996; Knutson et.al., 1990). It was because increases in food crop production, pesticide is use in most of the developed countries. The increase of food crop production is simply because the resistant for plant to grow is minimized. Weed growth, insect attack and fungi can affect the nutrient availability in the environment. By using pesticide, control of weed, insect and fungi can be done. Thus increase nutrients availability in the soil and it could maximised the condition for crop to grow (Hassall, 1980). 2.1.2 Effect of Pesticide Since the beginning of civilization, human want to enchanced their living condition. The enchancement of living included increase food production. The increase of food production can be enchanced by the used of pesticide. However, pesticide has cause serious problem (Gupta,2004 ; Gupta, 1989). The amount of pesticide in the environment may be little but It may post a threat. In India between the years of 1958 to 1992, there are a total of eight cases of pesticide poisoning in food (Gupta, 2004). Pesticide also post threat toward marine and fresh water living organism (Edge, et. al., 2014). There is a study in Tanzania shows that it is having a high concentration of pesticide. In this country, pesticide leak to the environement as a result from improper storage. It has cause pesticide to run off to the river. After the split, high concentration of pesticide is detected from soil ( Mahugijia et.al., 2013; Kishimba and Mihale, 2004). However, after 15 years the concentration of pesticide is still high in that area after the cleaning up process and the degradation of pesticide is found to be insignificant (Mahugija at. al., 2013). 2.2 Herbicide and It’s Mode of Actions Weed is defined as a wild plant growing where it is not wanted and in competition with cultivated plants (Soanes and Stevenson, 2009). The first man who use the term weed is Jethro TÃ…Â ±ll in his book name â€Å"The New Horse Hoeing Husbandary† in 1973. Jethro define weed as plant grow out of place, undesired plant on field, unwanted plant grow where it is not suppose to be, or plants and vegetation that obstruct plant growth. Thus, weed is undesirable plant growth (My agriculture information bank, 2011). The existence of weed will have impact toward crop. There is a case study in India that show interaction between weed and crop. The result shows a decrease in crop production. Whereby, wheat reduced by 15-30%, rice by 30-35%, maize, pulse, oilseed and sorghum reduces 18-85% each (Gupta, 2007; Mukhopppadhyay, 1991-92 Balyan and Malik, 1994, Rita et.al., 1995 and yadav et.al., 1995). Existence of weed is also troublesome in some area. When the weed is present on the field, it made the work hard for applying fertilizers and hard to harvest the crop. The present of weed in field may also provide shelter for pest to live and it will further reduce the crop productivity. Thus, the present of weed had cause 2.2.1 Amino Acid Sythesis Inhibitors 2.2.2 Photosystem II Inhibitors 2.2.3 Auxins Typerherbicides 2.2.4 Mitotic Inhibitors 2.2.5 Photosystem I Inhibitors 2.2.6 Cellulose Biosynthesis Inhibitors 2.3 Herbicide Resistance 2.4 Multicomponent Reactions 2.4.1 Ugi Reactions 2.4.2 Biginelli Reaction 2.4.3 Sakurai Reaction 2.4.4 Streacker Reaction 2.4.5 Mannich Reaction 2.4.6 Hanztch Reaction 2.4.7 Application of Multicomponent Reaction Chapter 3 Methodology 3.1 3.2 3.3 3.4 3.5 3.6 Chapter 4 Expected Result 4.1

Male and Female Roles in Sexual Selection :: Biology

Missing results graphs Why It Matters Sexual selection occurs across all species and is a key part of evolution. It allows animals to increase their fitness. Here are several interesting examples of cryptic female choice and male competition: 1) Males may perform courtship dances to show off their good genes. One species in which courtship dances can be observed are jumping spiders. Male spiders of this species wave their legs and arms to show females their abilities. Females choose a mate after seeing the dances. 2) One way for females to find a suitable mate is based on the resources a male will be able to provide. For instance, in the case of elephant seals, males fight over territories to win over a female. The â€Å"winner† of the fight shows the female that he has a territory and that he will be able to defend the offspring. 3) Additionally, in peacocks, the males have elaborate tails that attract females. Females choose a mate based on the ability of a male to show off his tail. The tail indicates to a female that a male has â€Å"good† genes to contribute to offspring. 4) In some animals, the roles of the genders may be switched. In seahorses, the males are responsible for giving birth and raising the offspring. In this case, males have more at stake and so the males are the â€Å"choosier† mate. They choose a female mate based on the female’s characteristics. 5) These ideas of sexual selection and cryptic female choice can be applied to humans. Women choose mates based on career perspectives, attractiveness, and resources. All these allow her to ensure her children will be healthy and successful. As you can see, it is important to research sexual selection across various species’. Similar mechanisms of selection are present in all animals. By learning how these mechanisms act in one species, it is possible to gain insight into the behavior of all animals, including human beings. Introduction Male Competition Versus Female Choice†¦ The sexual â€Å"arms race† is constantly going on within members of a species. While both male and female are trying to pass on their genes to the next generation, they both try to do this in a different way. Females are attempting to obtain genetic material from the best possible male in order to produce the fittest offspring, while males are trying solely to pass their own genes on to the next generation.

Own Business Essay

If I were to start my own business, the first decision I would make would be in deciding what product or service my company would produce or provide. For example, do I have a greater interest in the area of production or service? In deciding this, I would research the market to determine if there was a need for the product or service I was considering. I would also conduct research to determine what area (s) would be some of the better areas to begin the type of business I plan on undertaking. Things I might consider would be the competition, noticeable need for my product or service in the area and even presenting the idea at a public meeting in the area while evaluating the response I receive. Another key type of decision would be determining the size of the business. Along with determining for example whether the business would be a small business, medium-size or large business, I would need to determine the staffing needs of the business. As Al Coke stated in the book, â€Å"Seven Steps to a Successful Business Plan,† â€Å"What are your short-term and long-term staffing requirements? What kinds of skills will be needed at each level, now and in the future? † (Coke, 2002). Along the same line, what types of employees will be needed for the positions. If my company is involved in technology, I would need to hire individuals with training and education in the technology field. Deciding upon which tools and equipment will be needed for the operation of the business I have chosen would be another key decision needed to be made. For example, if I were considering opening a restaurant, I would need to look into the prices, types and sizes of the various commercial cooking equiptment available. One could include the company’s vision and mission statements as key decisions when starting up a company. As stated in Mr. Coke’s own words, â€Å"You must have two stakes in the ground to build a story and a subsequent business plan: vision and mission. One creates passion and the other provides purpose (Coke, 2002, p. 111). There would be different financial decisions to be made. For example, how much will I need or can I afford for start-up costs? What are the long-term capital investment requirements? In writing all of the financial decisions down, a good question to ask would be, â€Å"Do the financial numbers make good business sense? † (Coke, 2002, p. 33) Although the items listed above would just be some of the key decisions I would make when considering starting a business, I would definitely include a written business plan. In the business plan I would include information like that which I have listed above along with statistical information and data that I would use throughout my business inception and into the future.
