Pembertons dilemma free essay sample

Me and our team worked on an exercise called Pemberton’s Dilemma. In preparation, I was initially confused with scenario of the Pembertons dilemma. I took the book of Negotiation: Readings, Exercises and cases and read in detail regarding the exercise. I waited for the professor to provide the team and the role whether our team were country market or corner store. I also Read the instruction given in the handout’s for the exercise were we note our profit’s or loses and which also had the objective of the exercise. Plan Used to maximize the Profit’s or minimize the loses. We got the role of corner store. The plan that our team used initially was strictly competitive to gain profits since we don’t have any idea about the counter party and later it became accommodating. After we went a negotiation conversations with the counter party in two negotiation breaks’ which were of 5 minutes each. We will write a custom essay sample on Pembertons dilemma or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page As a team we planned from the instructions to gain profit against the counter party in order to maximize our team’s profits at any cost, but maximizing the profit along with a long-term relationship in the future was tough. I believe the strategy our team used was collaborative. At the end of the negotiation exercise both our team and counter party have equal profit’s along with good relationship. How plan was started and conversation went on in the Team As a team our member had an initial strategy that was communicated well , alternatively I have another way of moves so that our team opens the store for fewer week’s which reduces work load in handling the store open for less time and gaining profit’s when compared to the counter party opening the store more time . I later Identified in my plan the profit’s that were going to be made were less when compared with the proposal of our team member. When discussing, our initial moves are opening the store for the first four week’s since to maximize our profits and also as we don’t have any Idea regarding the actions of Country store team. Initially for the first three week’s both our teams opened the stored since we don’t want to lose the profit’s . But as the case If both opens each store loses 20,000 $ and we made loses. Even in the fourth week we did the same thing because the profits are going to be doubled. But we incurred losses since both of the teams had same intention and we both opened the stores. So we thought to have a negotiation with the counter team so that loses were going to be minized. Negotiation happened in break-At our first negotiation the team agreed to stick to our competitive strategy and maximize our profit at any cost. The counterpart’s strategy was also so the same. The counterpart agreed upon our discussion in order to maintain mutual benefit’s . We used the negotiation as an open opportunity to go against what was agreed on. At I believe both parties changed their strategies and had a collaborative decision. Continuation of the role play The corner store team then did accept our plan and went in a collaborative situation. We both closed the stores for the next three weeks so that each gained mutual benefits. Now the time came where the profits are going to be tripled. This is the time that we are going to trust each other. They remained loyal and we remained in the same loyalty and both closed the stores, so that no penalty is going to be levied and our profits for the week are in positive direction when compared to the previous week. Negotiation happened in break-2 So the constraints If only one store opens, the other loses. If both open, both lose. However, if both stay closed, there won’t be any penalty, but will lose the potential profits for that day. This is core to the whole idea of the prisoner’s dilemma. Through cooperation and negotiation methods we cannot have a higher return possible through action of one opening and the other closing unless their won’t be any penalty. So we both the corner store and the country store mutual interests are maximizing the profit’s . so we focused on the mutual gains. Continuation of the role play After the second negotiation took place with counter party. We continued the strategy of closing the next three weeks . Now the ultimate time has come. Since they came to negotiation with us without acting individually we have to be trust worthy. We didn’t play any dirty tricks and kept the same hope from them by our conversation with them in the negotiation breaks and even in the role play . On the top the alternate opening or closing of stores and our relationship continuous only we both have trust in each other even after the twelfth week. Even at the final point the counterpart stayed closed along with us. Our only possible threat was what if they went against us mutual benefits. But it didn’t happen. Observing the gestures Following our competitive plan, we didnt express any type of attitude , we had relaxed actions and made no facial expressions. Even the counter party has the same behavior. Their behaviors made us believe that the counterpart was following us for mutual benefits. Personal Evaluation When we are working in a team relating to any aspect we first must have a communication with other members of the team so that we can have small ideas regarding their ideas or behaviors . So I introduce myself to other and listened about the others. Initially as I thought a plan of implementing the role-play, the other team member has another idea. As in my plan our store work’s less than other store and gains same profits. But the plan of my other team member is different. so I separated my position with my interest and agreed upon his opinion. Learning from the exercise I believe the team was able to utilize the Negotiation methods: separating positions from problems and inventing options for mutual, examining the situation and assessing the relationship further. If both teams utilized an interest based negotiation, we might have been able to form a collaborative and comprehensive solution to any negotiation. What I would do different in a similar future situation in my personal or professional life is try and understand thoroughly the problem at hand and be able to recognize the main interests and invent the options for mutual gains along with a Banta (Best alternative to a negotiation agreement) , unless the other party don’t play any dirty tricks.

Manhattan Project essays

Manhattan Project essays "Nor do I take into account a danger of starting a chain reaction of a scope great enough to destroy part or all of the planet ... But it is not necessary to imagine the earth being destroyed like a nova by a stellar explosion to understand vividly the growing scope of atomic war and to recognize that unless another war is prevented it is likely to bring destruction on a scale never before held possible, and even now hardly conceived, and that little civilization would survive it." Albert Einstein Since the beginning of time men have found cause to go to war with one another. War has built nations into great powers while bringing others to great ruin. Because of the threat of war, and the possibility of being conquered, countries put great importance on the strength of their military. In an attempt to gain the edge against their enemies they constantly try to have the most effective weapons so they can inflict the most possible damage on the opponent while minimizing their own damage sustained. New weapons have revolutionized the state of warfare throughout history, and caused great concern. For example, there was widespread concern with the advent of the crossbow in the Middle Ages; an untrained peasant was now able to kill a knight who had been trained in the art of warfare his entire life. The crossbow changed the way battles had to be fought. There have been many new weapons of war that have been so influential that they have changed the way wars were fought. Ho wever, no weapon in history has been as influential as the nuclear bomb developed by the United States in 1945. While other revolutionary new weapons might turn the tide of battle and may even cause entire countries to be defeated, if two countries ever became involved in a full scale nuclear war, the world would end as we know it. In 1939 the world was on the brink of war. Germanys war machine was on the move and its best and brightest scien...

Types of Formatting for Academic Papers

Types of Formatting for Academic Papers Types of Formatting for Academic Papers Teachers commonly require academic papers to assess a student’s comprehension of a topic. Academic assessments often come in the form of research papers, which are defined as a person’s thoughts or perception of a topic based on thorough analysis. When writing an academic paper, be mindful of the following things. Common Types of Academic Papers Definition Papers Definition papers describe an idea from a factual perspective. These papers do not contain opinion or emotion. Although you may gather facts from different sources, the information is simply stated and supported. However, a definition paper can provide a good framework for persuasive, argumentative, or analytical papers. Argumentative Papers Argumentative papers present two sides of a scenario in one paper. Most good argumentative papers include in-text citations from different researchers and logical facts in support of both sides of the argument. Ultimately, these facts should conclude and culminate your analysis with the pros and cons of each side. The challenge in writing an argumentative paper is that while you are advocating for one side over the other, the way in which you present both arguments must remain neutral and factual. Persuasive Papers Persuasive papers choose a stance and provide logical arguments to defend that stance. Unlike argumentative papers, persuasive papers do not need to present ideas that support any opposing stance. It can also include more emotional and perspective-based opinions. Purpose of Academic Paper Formats When writing academic papers, the way you present your paper is crucial. Using the proper citing, referencing, and quoting of your sources allow for you to communicate your ideas in a manner that is shared by others in your field. Some of these formats include: Chicago Manual of Style The Chicago Manual of Style (CMS) is predominantly used in humanities, particularly literature, history, or the arts. Modern Language Association Style The Modern Language Association Style (MLA) is also popular with students of humanities. Artists, linguists, and theatre students have been using MLA for over 500 years. American Psychological Association Style The American Psychological Association Style (APA) is a set of rules and guidelines established by the American Psychological Association. This format is popular among students and practitioners of psychology, sociology, social work, and medicine. When working on your research paper, remember to pay extra attention to the way you format your source materials. Use the handouts that your teachers give you, or any online reference materials to ensure that all formatting is accurate. For expert advice in formatting your research paper, is here to help.

LLB Law - Contract Law Case Study Example | Topics and Well Written Essays - 750 words

LLB Law - Contract Law - Case Study Example The offer was communicated to Mr Taylor at the price agreed of 35,000 to be payable 24 March, the costumes to be delivered on the same day. Studying this case one must also remember that the definition of consideration is extremely important and relevant. In Currie v Misa (1875) the definition of consideration is clearly understood as a right, interest, profit or benefit to one party, or some forbearance, detriment suffered or undertaken by another. Consideration is the normal 'badge of enforcement' in English Law. Taking a further look at this case the consideration was the amount of money that Mr Baron offered to Mr Taylor in exchange for the goods at the promised time. However Mr Taylor suffered detriment when the full amount of money was not paid. Consideration was given when Mr Baron asked for all all the costumes for the waiters to be delivered before the club opened. Mr Taylor met all the requirements for the contract to be valued whereas Mr Baron did not fulfill the requirements of the contract. The case also deals with executed consideration, for this to be the case there are certain criteria that must be satis fied. In LAMPLEIGH v BRAITWAIT (1615) it was held that the act must have been requested by the promisor. As seen in Mr Baron's case he made the request for the costumes. As per RE CASEY's PATENT (1892) there was an understanding that payment would be made once all the costumes were delivered to Mr Baron for the full amount that he promised. Mr Baron did not pay the full amount he promised on delivery of the goods. Consequently he breached the terms of the contract and Mr Taylor suffered damage. There was an intention to be bound as in the case of Carlill v Carbolic Smoke Ball Co [1893] 1 QB 256. Other cases have studied the laws of intention such as; Rose and Frank Co v JR Crompton & Bros [1923] There was a clear intention on the part of Mr Baron to create legal relations since he communicated his needs when he found out that Mr Taylor's staff were far behind with their work and that the costumes may not be finished by opening night. Mr Baron clearly wanted the work carried out and clearly communicated the amount of money he wanted in return for the goods. When Mr Baron realized that the goods might not be ready for opening time he communicated a new agreement that he would pay a further 3000 only if the goods were ready in time for opening. This resulted in Mr Taylor requesting all of his workers to design Mr Baron's costumes exclusively. Therefore Mr Taylor was running at a loss if Mr Baron did not pay the full amount since he could not ask his workers to work on anything else during this time period. This resulted in damages to Mr Taylor and his company when Mr Baron refused to keep his promise and pay the full amount. This relates to the decision made in WILLIAMS v ROFFEY BROS(1991), where it was held that where a party to an existing

Write an essay arguing that Emily Grierson relationshi with her father

Write an arguing that Emily Grierson relationshi with her father contributed to her tragedy - Essay Example The description of Emily’s father was presented in paragraph 25 as a â€Å"spraddled silhouette in the foreground, his back to her and clutching a horsewhip† (Faulkner 25; cited in Kennedy and Gioia). Likewise, as noted, none of the young men were deemed good enough for Emily and that the townsfolk â€Å"remembered all the young men her father had driven away† (Faulkner 28). In addition, there was emphasis noted to the fact that â€Å"the Griersons held themselves a little too high for what they really were† (Faulkner 25). Due to the extreme sheltered existence given to Emily and the prevention of her father to find a suitable man as her husband, Emily remained isolated all her life. By the time her father died, there could actually be some manifestations of mental illness or insanity as it was revealed that Emily refused to admit her father’s death. When the townswomen came to offer their condolences, it was revealed that â€Å"Miss Emily met them at the door, dressed as usual and with no trace of grief on her face. She told them that her father was not dead. She did that for three days, with the ministers calling on her, and the doctors, trying to persuade her to let them dispose of the body. Just as they were about to resort to law and force, she broke down, and they buried her father quickly† (Faulkner 27). The length of time spent totally dependent on her father could have instigated the innate fear of being left alone and therefore, Emily could not accept the fact that this fear was in fact a reality. Alone and afraid in the house with nothing left to support or sustain her daily living, Emily’s life succumbed to depression and anxiety . When a potential lover in the person of Homer Barron came to her life, the hope of having someone to spend her life with was just what she needed. However, as the story unfolded, it was revealed that Homer Barron, who the townsfolk

Precision Agriculture: Advantages and Disadvantages

Precision Agriculture: Advantages and Disadvantages Precision agriculture Precision farming or precision agriculture is an agricultural concept relying on the existence of in-field variability. It requires the use of new technologies, such as global positioning (GPS), sensors, satellites or aerial images, and information management tools (GIS) to assess and understand variations. Collected information may be used to more precisely evaluate optimum sowing density, estimate fertilizers and other inputs needs, and to more accurately predict crop yields. It seeks to avoid applying inflexible practices to a crop, regardless of local soil/climate conditions, and may help to better assess local situations of disease or lodging. Satellites allow farmers to easily survey their land.[2] Global Positioning Systems (GPS) monitor can find the location of a field to within one meter. It can then present a series of GIS maps that demonstrate which fields are moist or dry, and where there is erosion of soil and other soil factors that stunt crop growth. The data can be used by the farmer to automatically regulate the machine application of fertilizer and pesticide[2]. In the American Midwest (US) it is associated not with sustainable agriculture but with mainstream farmers who are trying to maximize profits by spending money only in areas that need fertilizer. This practice allows the farmer to vary the rate of fertilizer across the field according to the need identified by GPS guided Grid Sampling. Fertilizer that would have been spread in areas that dont need it can be placed in areas that do, thereby optimizing its use. Precision farming may be used to improve a field or a farm management from several perspectives: agronomical perspective: adjustment of cultural practices to take into account the real needs of the crop (e.g., better fertilization management) technical perspective: better time management at the farm level (e.g. planning of agricultural activity) environmental perspective: reduction of agricultural impacts (better estimation of crop nitrogen needs implying limitation of nitrogen run-off) economical perspective: increase of the output and/or reduction of the input, increase of efficiency (e.g., lower cost of nitrogen fertilization practice) Other benefits for the farmer geostatistics integrated farming Integrated Pest Management nutrient budgeting nutrient management precision viticulture Agriculture Landsat program Geostatistics is a branch of statistics focusing on spatiotemporal datasets. Developed originally to predict probable distributions for mining operations, it is currently applied in diverse disciplines including petroleum geology, hydrogeology, hydrology, meteorology, oceanography, geochemistry, geometallurgy, geography, forestry, environmental control, landscape ecology, soil science, and agriculture (esp. in precision farming). Geostatistics is applied in varied branches of geography, particularly those involving the spread of disease (epidemiology), the practice of commerce and military planning (logistics), and the development of efficient spatial networks. Geostatistics are incorporated in tools such as geographic information systems (GIS) and digital elevation models. History This section requires expansion with: details. Background When any phenomena is measured, the observation methodology will dictate the accuracy of subsequent analysis; in geography, this issue is complicated by unique variables and spatial patterns such as geospatial topology. An interesting feature in geostatistics is that every location displays some form of spatial pattern, whether in the form of the environment, climate, pollution, urbanization or human health. This is not to state that all variables are spatially dependent, simply that variables are incapable of measurement separate from their surroundings, such that there can be no perfect control population. Whether the study is concerned with the nature of traffic patterns in an urban core, or with the analysis of weather patterns over the Pacific, there are always variables which escape measurement; this is determined directly by the scale and distribution of the data collection, or survey, and its methodology. Limitations in data collection make it impossible to make a direct meas ure of continuous spatial data without inferring probabilities, some of these probability functions are applied to create an interpolation surface predicting unmeasured variables at innumerable locations.

It may require cleanup to comply with Wikipedias content policies, particularly neutral point of view. Please discuss further on the talk page. ({{{November 2009}}}) Jan W Merks, a mineral sampling expert consultant from Canada, has strongly criticized[1] geostatistics since 1992. Referring to it as voodoo science[2] and scientific fraud, he claims that geostatistics is an invalid branch of statistics. Merks submits[2] that geostatistics ignores the variance of Agterbergs distance-weighted average point grade, ignores the concept of degrees of freedom of a data set when testing for spatial dependence by applying Fishers F-test to the variance of a set and the first variance term of the ordered set, abuses statistics by not using analysis of variance properly, replaced genuine variances of single distance-weighted average point grades with pseudo-variances of sets of distance-weighted average point grades, violating the one-to-one correspondence between variances and functions such as Agterbergs distance-weighted average point grade. Furthermore, Merks claims geostatistics inflates mineral reserve and resources such as in the case of Bre-Xs fraud. Merkss expertise and credibility are supported by several company executives, who regularly hire his consulting services[3]. Philip and Watson have also criticized geostatistics in the past [4]. There is a consensus that inappropriate use of geostatistics makes the method susceptible to erroneous reading of results[3][5]. Related software gslib is a set of fortran 77 routines (open source) implementing most of the classical geostatistics estimation and simulation algorithms sgems is a cross-platform (windows, unix), open-source software that implements most of the classical geostatistics algorithms (kriging, Gaussian and indicator simulation, etc) as well as new developments (multiple-points geostatistics). It also provides an interactive 3D visualization and offers the scripting capabilities of python. gstat is an open source computer code for multivariable geostatistical modelling, prediction and simulation. The gstat functionality is also available as an S extension, either as R package or S-Plus library. besides gstat, R has at least six other packages dedicated to geostatistics and other areas in spatial statistics.

It refers to agricultural systems that integrate livestock and crop production and may sometimes be known as Integrated Biosystems. While not often considered as part of the permaculture movement Integrated Farming is a similar whole systems approach to agriculture[1]. There have been efforts to link the two together such as at the 2007 International Permaculture Conference in Brazil[2]. Agro-ecology (which was developed at University of California Santa Cruz) and Bio-dynamic farming also describe similar integrated approaches. Examples include: pig tractor systems where the animals are confined in crop fields well prior to planting and plow the field by digging for roots poultry used in orchards or vineyards after harvest to clear rotten fruit and weeds while fertilizing the soil cattle or other livestock allowed to graze cover crops between crops on farms that contain both cropland and pasture (or where transhumance is employed) Water based agricultural systems that provide way for effective and efficient recycling of farm nutrients producing fuel, fertilizer and a compost tea/mineralized irrigation water in the process. In 1993 FARRE (Forum de lAgriculture Raisonnà ©e Respecteuse lEnvironnement) developed agricultural techniques France as part of an attempt to reconcile agricultural methods with the principles of sustainable development. FARRE, promotes an integrated and/or multi-sector approach to food production that includes profitability, safety, animal welfare, social responsibility and environmental care. Zero Emissions Research and Initiatives (formed in 1994 by the eco-entrepreneur [1]) developed a similar approach to FARRE seeking to promote agricultural and industrial production models that sought to incorporate natures wisdom into the process. ZERI helped support an effort by an environmental engineer from Mauritius named George Chan. Chan working with a network of poly-culture farming pioneers began refining Integrated Farming practices that had already been developed in south-east Asia in the 60,70s and 80s, building on the ancient Night soil farming practice. In China, programs embracing this form of integrated farming have been successful in demonstrating how an intensive growing systems can use organic and sustainable farming practices, while providing a high agriculture yield. Taking what he learned from the Chinese during his time there, Chan worked at the UN University in the 1990s and forwarded an approach to Integrated Farming which was termed Integrated Biomass Systems working specifically under the UNU/ZERI ZERI Bag Program. Chan during his work with UNU sought to make the case that Integrated Biomass Systems were well suited to help small island nations and low lying tropical regions become more self-reliant and prosperous in the production of food[3]. Working with ZERI, he developed several prototypes for this approach around the world including sites in Namibia and Fiji. The scientifically verified results in a UNDP sponsored congress in 1997 resulted in the adoption of the IBS by the State Government of Paranà ¡, Brazil where dozens of piggeries have applied the system generating food, energy while improving health and environmental conditions. Montfort Boys Town in Fiji was one of the first Integrated Biomass Systems developed outside of Southeast Asia with the support of UNU, UNDP and other international agencies. The project which is still operational continues to be a model of how farm operations can provide multiple benefits to stakeholders both local and international. ZERI Bag had a significant African component that included assisting Father Godfrey Nzamujo in the development of the Songhai Farm Integrated Farming project in Benin[4] . Most recently The Heifer Foundation a major international NGO based in the USA has taken a lead role in deploying Integrated Farming so that it can be replicated globally as an effective approach to sustainable farming in non-affluent regions such as Vietnam[5].

These methods are done in three stages: prevention, observation, and intervention. It is an ecological approach with a main goal of significantly reducing or eliminating the use of pesticides while at the same time managing pest populations at an acceptable level.[1] For their leadership in developing and spreading IPM worldwide, Dr. Perry Adkisson and Dr. Ray F. Smith received the 1997 World Food Prize. History of IPM Shortly after World War II, when synthetic insecticides became widely available, entomologists in California developed the concept of supervised insect control. Around the same time, entomologists in cotton-belt states such as Arkansas were advocating a similar approach. Under this scheme, insect control was supervised by qualified entomologists, and insecticide applications were based on conclusions reached from periodic monitoring of pest and natural-enemy populations. This was viewed as an alternative to calendar-based insecticide programs. Supervised control was based on a sound knowledge of the ecology and analysis of projected trends in pest and natural-enemy populations. Supervised control formed much of the conceptual basis for the integrated control that University of California entomologists articulated in the 1950s. Integrated control sought to identify the best mix of chemical and biological controls for a given insect pest. Chemical insecticides were to be used in manner least disruptive to biological control. The term integrated was thus synonymous with compatible. Chemical controls were to be applied only after regular monitoring indicated that a pest population had reached a level (the economic threshold) that required treatment to prevent the population from reaching a level (the economic injury level) at which economic losses would exceed the cost of the artificial control measures. IPM extended the concept of integrated control to all classes of pests and was expanded to include tactics other than just chemical and biological controls. Artificial controls such as pesticides were to be applied as in integrated control, but these now had to be compatible with control tactics for all classes of pests. Other tactics, such as host-plant resistance and cultural manipulations, became part of the IPM arsenal. IPM added the multidisciplinary element, involving entomologists, plant pathologists, nematologists, and weed scientists. In the United States, IPM was formulated into national policy in February 1972 when President Nixon directed federal agencies to take steps to advance the concept and application of IPM in all relevant sectors. In 1979, President Carter established an interagency IPM Coordinating Committee to ensure development and implementation of IPM practices. (references: The History of IPM, BioControl Reference Center. [1] How IPM works An IPM regime can be quite simple or sophisticated. Historically, the main focus of IPM programs was on agricultural insect pests.[2] Although originally developed for agricultural pest management, IPM programs are now developed to encompass diseases, weeds, and other pests that interfere with the management objectives of sites such as residential and commercial structures, lawn and turf areas, and home and community gardens. An IPM system is designed around six basic components: The US Environmental Protection Agency has a useful set of IPM principles. [2] 1. Acceptable pest levels: The emphasis is on control, not eradication. IPM holds that wiping out an entire pest population is often impossible, and the attempt can be more costly, environmentally unsafe, and frequently unachievable. IPM programs first work to establish acceptable pest levels, called action thresholds, and apply controls if those thresholds are crossed. These thresholds are pest and site specific, meaning that it may be acceptable at one site to have a weed such as white clover, but at another site it may not be acceptable. This stops the pest gaining resistance to chemicals produced by the plant or applied to the crops. If many of the pests are killed then any that have resistance to the chemical will rapidly reproduce forming a resistant population. By not killing all the pests there are some un-resistant pests left that will dilute any resistant genes that appear. 2. Preventive cultural practices: Selecting varieties best for local growing conditions, and maintaining healthy crops, is the first line of defense, together with plant quarantine and cultural techniques such as crop sanitation (e.g. removal of diseased plants to prevent spread of infection). 3. Monitoring: Regular observation is the cornerstone of IPM. Observation is broken into two steps, first; inspection and second; identification.[3] Visual inspection, insect and spore traps, and other measurement methods and monitoring tools are used to monitor pest levels. Accurate pest identification is critical to a successful IPM program. Record-keeping is essential, as is a thorough knowledge of the behavior and reproductive cycles of target pests. Since insects are cold-blooded, their physical development is dependent on the temperature of their environment. Many insects have had their development cycles modeled in terms of degree days. Monitor the degree days of an environment to determine when is the optimal time for a specific insects outbreak. 4. Mechanical controls: Should a pest reach an unacceptable level, mechanical methods are the first options to consider. They include simple hand-picking, erecting insect barriers, using traps, vacuuming, and tillage to disrupt breeding. 5. Biological controls: Natural biological processes and materials can provide control, with minimal environmental impact, and often at low cost. The main focus here is on promoting beneficial insects that eat target pests. Biological insecticides, derived from naturally occurring microorganisms (e.g.: Bt, entomopathogenic fungi and entomopathogenic nematodes), also fit in this category. 6. Chemical controls: Synthetic pesticides are generally only used as required and often only at specific times in a pests life cycle. Many of the newer pesticide groups are derived from plants or naturally occurring substances (e.g.: nicotine, pyrethrum and insect juvenile hormone analogues), and further biology-based or ecological techniques are under evaluation. IPM is applicable to all types of agriculture and sites such as residential and commercial structures, lawn and turf areas, and home and community gardens. Reliance on knowledge, experience, observation, and integration of multiple techniques makes IPM a perfect fit for organic farming (the synthetic chemical option is simply not considered). For large-scale, chemical-based farms, IPM can reduce human and environmental exposure to hazardous chemicals, and potentially lower overall costs of pesticide application material and labor. 1. Proper identification of pest What is it? Cases of mistaken identity may result in ineffective actions. If plant damage due to over-watering are mistaken for a fungal infection, a spray may be used needlessly and the plant still dies. 2. Learn pest and host life cycle and biology. At the time you see a pest, it may be too late to do much about it except maybe spray with a pesticide. Often, there is another stage of the life cycle that is susceptible to preventative actions. For example, weeds reproducing from last years seed can be prevented with mulches. Also, learning what a pest needs to survive allows you to remove these. 3. Monitor or sample environment for pest population How many are here? Preventative actions must be taken at the correct time if they are to be effective. For this reason, once you have correctly identified the pest, you begin monitoring BEFORE it becomes a problem. For example, in school cafeterias where roaches may be expected to appear, sticky traps are set out before school starts. Traps are checked at regular intervals so you can see them right away and do something before they get out of hand. Some of the things you might want to monitor about pest populations include: Is the pest present/absent? What is the distribution all over or only in certain spots? Is the pest population increasing or decreasing? 4. Establish action threshold (economic, health or aesthetic) How many are too many? In some cases, a certain number of pests can be tolerated. Soybeans are quite tolerant of defoliation, so if you have only a few caterpillars in the field and their population is not increasing dramatically, there is no need to do anything. Conversely, there is a point at which you MUST do something. For the farmer, that point is the one at which the cost of damage by the pest is MORE than the cost of control. This is an economic threshold. Tolerance of pests varies also by whether or not they are a health hazard (low tolerance) or merely a cosmetic damage (high tolerance in a non-commercial situation). Personal tolerances also vary many people dislike any insect; some people cannot tolerate dandelions in their yards. Different sites may also have varying requirements based on specific areas. White clover may be perfectly acceptable on the sides of a tee box on a golf course, but unacceptable in th e fairway where it could cause confusion in the field of play.[4] 5. Choose an appropriate combination of management tactics For any pest situation, there will be several options to consider. Options include, mechanical or physical control, cultural controls, biological controls and chemical controls. Mechanical or physical controls include picking pests off plants, or using netting or other material to exclude pests such as birds from grapes or rodents from structures. Cultural controls include keeping an area free of conducive conditions by removing or storing waste properly, removing diseased areas of plants properly. Biological controls can be support either through conservation of natural predators or augmentation of natural predators[5]. Augmentative control includes the introduction of naturally occurring predators at either an inundative or inoculative level[6]. An inundative release would be one that seeks to inundate a site with a pests predator to impact the pest population[7][8]. An inoculative release would be a smaller number of pest predators to supplement the natural population and provide ongoing control.[9] Chemical controls would include horticultural oils or the application of pesticides such as insecticides and herbicides. A Green Pest Management IPM program would use pesticides derived from plants, such as botanicals, or other naturally occurring materials. 6. Evaluate results How did it work? Evaluation is often one of the most important steps.[10] This is the process to review an IPM program and the results it generated. Asking the following questions is useful: Did your actions have the desired effect? Was the pest prevented or managed to your satisfaction? Was the method itself satisfactory? Were there any unintended side effects? What will you do in the future for this pest situation? Understanding the effectiveness of the IPM program allows the site manager to make modifications to the IPM plan prior to pests reaching the action threshold and requiring action again.

How to Improve Your English

Language plays and important role in human life. Out of all the languages in the world, English is considered as the international language. And me as an immigrant I think it’s very important to work on improving my English skills in order to communicate with people easier, get more job opportunities, and most importantly to get into college. There are plenty of ways to improve your English. To improve your English conversation and oral skills you should watch American movies and T. V. shows with English subtitles, and try to really listen!You should also try and communicate as much as you can and don’t be shy of your accent or your lack of grammar, just know that you’re doing this for the best and to have better English in the future. Personally that helped me a lot and I would strongly advise any person who’s looking to improve their English to use this method. Now if you want to improve your reading skills, just simply, read! Read anything and everythin g in English. You can read story books, newspapers, magazines, blogs, comics, English textbooks, instructions and ingredients on food packages, advertisements or even online articles if you want.Honestly, in our days just going on the internet can be a lot of reading, and with the internet being most in English, it would be a very good and fun way for you to improve your reading and reading speed. However, always remember, do something, anything. Just don’t do nothing, because if you don’t do anything, you will not get anywhere. Don't be in too much of a hurry though. You're setting off on a long journey and there'll be delays and frustrations along the way. Sometimes you'll be in the fast lane and other times you'll be stuck in traffic, just take your time to really enjoy the experience.
