Do Insects Hibernate in the Winter

Do Insects Hibernate in the Winter An insect doesn’t have the benefit of body fat, like bears and groundhogs, to survive freezing temperatures and keep internal fluids from turning to ice. Like all ectotherms, insects need a way to cope with fluctuating temperatures in their environment. But do insects hibernate? In a very general sense, hibernation refers to the state in which animals pass the winter.1 Hibernation suggests the animal is in a dormant state, with its metabolism slowed and reproduction paused. Insects dont necessarily hibernate the way warm-blooded animals do. But because the availability of host plants and food sources are limited during the winter in cold regions, insects do suspend their usual activities and enter a dormant state. So how do insects survive the cold winter months? Different insects use different strategies to avoid freezing to death when the temperature falls. Some insects employ a combination of strategies to survive the winter. Migration When it gets cold, leave! Some insects head to warmer climes, or at least better conditions, when winter weather approaches. The most famous migrating insect is the monarch butterfly. Monarchs in the eastern U.S. and Canada fly up to 2,000 miles to spend their winter in Mexico. Many other butterflies and moths also migrate seasonally, including the gulf fritillary, the painted lady, the black cutworm, and fall armyworm. Common green darners, dragonflies that inhabit ponds and lakes as far north as Canada, migrate as well. Communal Living When it gets cold, huddle up! There’s warmth in numbers for some insects. Honey bees cluster together as the temperatures drop, and use their collective body heat to keep themselves and the brood warm. Ants and termites head below the frost line, where their large numbers and stored food keep them comfortable until spring arrives. Several insects are known for their cool weather aggregations. Convergent lady beetles, for example, gather en masse on rocks or branches during spells of cold weather. Indoor Living When it gets cold, move inside! Much to the displeasure of homeowners, some insects seek shelter in the warmth of human dwellings when winter approaches. Each fall, peoples houses are invaded by box elder bugs, Asian multicolored lady beetles, brown marmorated stink bugs, and others. While these insects rarely cause damage indoors – theyre just looking for a cozy place to wait out the winter – they may release foul-smelling substances when threatened by a homeowner trying to evict them. Torpor When it gets cold, stay still! Certain insects, particularly ones that live in higher altitudes or near the Earth’s poles, use a state of torpor to survive drops in temperature. Torpor is a temporary state of suspension or sleep, during which the insect is completely immobile. The New Zealand weta, for example, is a flightless cricket that lives in high altitudes. When temperatures drop in the evening, the cricket freezes solid. As daylight warms the weta, it comes out of the torpid state and resumes activity. Diapause When it gets cold, rest! Unlike torpor, diapause is a long-term state of suspension. Diapause synchronizes the insect’s life cycle with seasonal changes in its environment, including winter conditions. Put simply, if it’s too cold to fly and there’s nothing to eat, you might as well take a break (or pause). Insect diapause may occur in any stage of development: Eggs – Praying mantids survive the winter as eggs, which emerge in spring.Larvae – Woolly bear caterpillars curl up in thick layers of leaf litter for winter. In spring, they spin their cocoons.Pupa – Black swallowtails spend winter as chrysalids, emerging as butterflies when warm weather returns.Adults – Mourning cloak butterflies hibernate as adults for the winter, tucking themselves behind loose bark or in tree cavities. Antifreeze When it gets cold, lower your freezing point! Many insects prepare for the cold by making their own antifreeze. During the fall, insects produce glycerol, which increases in the hemolymph. Glycerol gives the insect body â€Å"supercooling† ability, allowing body fluids to drop below freezing points without causing ice damage. Glycerol also lowers the freezing point, making insects more cold-tolerant, and protects tissues and cells from damage during icy conditions in the environment. In spring, glycerol levels drop again.

Hate Crime Legislation essays

Hate Crime Legislation essays Much of society today revolves around people's differences. We are confronted on a daily basis by issues such as Affirmative Action, Gay rights, and Women's rights. Race, religion, sexual orientation, and gender can affect your working and social lives in a very serious way. People seem to be getting more and more determined to get more acceptance and tolerance for differences. Common catch phrases of the last few years have included "Equal Rights For All" and "Celebrate Diversity." The celebration of diversity is an interesting concept. Society tells us to be proud our differences. If you are gay, straight, Jewish, Shinto, Ethiopian, Indonesian, or an interesting combination somewhere in the middle, celebrate it, because having differences is what makes our society strong. This is where hate crime legislation comes in. Hate crime legislation punishes people who refuse to tolerate difference and express their refusal in violent or nonviolent illegal ways. Hate crime legislation is essentially the idea that hate crimes should carry harsher penalties than other crimes. The same crime committed with different motives would hold different consequences. Under this premise, hate crime legislation should be realized to be unconstitutional and should not be permitted. Congress defines a hate crime as "a crime in which the defendant intentionally selects a victim, or in the case of a property crime, the property that is the object of the crime, because of the actual or perceived race, color, national origin, ethnicity, gender, disability, or sexual orientation of any person"(Congress).

Kiva Microfinance and the Future China Essay Example | Topics and Well Written Essays - 500 words

Kiva Microfinance and the Future China - Essay Example The major challenge faced by Kiva microfinance is the emergence of other organizations that deal in similar same services it offers. Government policies had been established to permit loan granting organization leading to business competition. This calls for vigilance on how Kiva invests their money or grant loans. The sole reason for the establishment of many loans granting corporations is to help the country grow economically (Sinclair, 36). These have allowed lender borrow a large amount of money as compared to other days. This is because the law charges the same interests between 3,000 and 10,000 thus lenders give out large loans so as to get high interest in return. The setback has resulted in irresponsible money lending with Kiva since it is not logical for a poor person to borrow one million to start a business because there is no guarantee that the money will be refunded. It is noted that 20% and below of the money given out as loans serve the rural population whereby it is t he farmers and small scale business people who benefit a lot from this micro-finance organization. In conclusion, a lot of development is expected in Kiva microfinance to help the eradication of poverty globally. Kiva micro-finance is working with various nations to ensure that people are encouraged and taught some of the basic enterprenual concepts. Due to the population increment, Kiva aims at providing loans to the jobless to help avoid an increase in criminal cases. Loans help those with enterprenual skills meet some of the long-term goals.

Six Sigma And Lean In Helthcare Research Paper Example | Topics and Well Written Essays - 3500 words

Six Sigma And Lean In Helthcare - Research Paper Example Six Sigma and Lean Systems (SS/L) are extremely popular tools for the improving quality. Therefore, they provide the managers of Healthcare with the opportunity to improve the quality of healthcare on the basis of using sound methodologies and data. Cost increase control in the healthcare, improving the quality, and the provision of better Healthcare are some of the main benefits of this approach. However, these two quality improvement tools are not clear to many whether they are capable of improving the quality of healthcare. Thus, this research paper clearly illustrates how effective these tools can be and what can be corrected to improve further. This will go an extra mile in helping the health care sector, to render high quality services and achieve considerable accolades, as far as, Healthcare services are concerned. In the recent past, medical care has become exceedingly expensive to an extent that many are not in apposition to access healthcare particularly in the underdeveloped and some of the developing world. Considerable amount of cost increase can be attributed to the out dated technology, and an aging population, which is inevitable due to the advancement of technology and modern demographic developments, which are beyond control. On top of that, operational inefficiency also contributes to the Healthcare cost increase, and this has to do with the healthcare professionals. Inefficiency in this research study is of much essence as it can be measured and necessary changes implemented to improve on the quality. This will lead to affordable Healthcare services and of better quality to a considerable percentage of the entire global population. Some inefficiency encountered in the process of operation can be connected to the delivery of services in the medical sector. Other inefficiencies arise as a result of logistical, administrative and healthcare delivery system operations, of which both can be extremely beneficial to the systematic process of innovation. The paper seeks to evaluate the importance of the Six Sigma and Lean approaches in the healthcare sector. Looking critically at the industrial sector, in the past century, it deployed massive machinery and innovation approaches to increase their level of operational approaches and hence achieve high levels of efficiency in operation systems (Jones, Roos, & Womack, 1990). On evaluating the history of economy, the efficiencies in the industry, were obtained from the collective effect of a substantial number of incremental improvements (Rosenberg, 1982). Six Sigma and Lean Thinking are two processes of an innovative approach that have gained much popularity in the industrial sector (Robinson, 1990). They both availed a systematic approach that facilitated process geared towards increasing the magnitude of innovations. A ccording to Ohno (1988), Lean Thinking emerged in the automobile industry of Japan after the World War II, though it can be traced to the earlier days of the Ford Motor Company (Ford and Crowther, 1926). Six Sigma was originally brought to be by Motorola, and culminated to the synthesis of a

Mason and Shepherd' difficulties Case Study Example | Topics and Well Written Essays - 750 words

Mason and Shepherd' difficulties - Case Study Example The clause 1, 2 and 4 of her contract exclusively forbid her to share any information that is related to the company, its associates and customers or is linked in anyway to its wider interests. The contract is also explicit in that during the employment period and within one year of leaving present employment, she cannot engage in any business or activity that is in direct or indirect competition to the existing area of operation of ATS. As per clause 6, the company has also claim to any new idea that may significantly impact organizational work output and performance. Shepherd’s employment contract also forbids him to share company’s information. At the same time, it also ensures that his employer, Nova Software Company will have claim to any new idea, discovery or development that are conceived during the period of employment and which has direct bearing on the wider ramifications on the operations and performance of the company. Thus, both Mason and Shepherd are in h ighly precarious ground vis-a-vis their employment conditions. There are huge legal and ethical issues that are being violated by Mason and Shepherd. Shepherd was inspired for his new ideas for developing translation software by observing the pros and con of the software developed by his previous employer, Riverhead. But it was only after working for ten years at Nova that he decided to seriously work on translation engine. The new software would expedite the portability of software developed by Nova and other companies on myriad operating systems. Hence, by default the company has claim to the idea and development of translation engine which would complement the software developed by the Nova. Mason has also been exploiting her contacts, developed during her employment at ATS for her own vested interests. She has also been highly unethical in accessing and using confidential information for her personal gain. Mason and Shepherd are both in serious trouble. They now not only need to give advance notice for their resignation but also hire the services of a lawyer who could defend them in the court of law for breach of confidential information, violation of employment contract on various level and for also protecting their future interests vis-a-vis their creative input. Therefore, Mason and Shepherd must hand over their resignation, give advance notice and also take legal recourse to counter any claim by their employers. Answer 2 The non disclosure agreement as prepared by Mason and Shepherd for the prospective venture capitalists lacks professional vision and rational approach. The agreement prohibits the VCs to discuss the wider ramifications of the project with other investors or specialists for its feasibility. The VCs are independent investors who would need to ensure the viability of project before they decide to fund the project. They are also inundated with requests for funding the projects from other businesses and individuals. Thus, it would become hi ghly difficult for VCs to differentiate minor differences amongst the innovative software from different developers. Hence, disclosure agreement must give leverage to VCs so that they can confer with other experts in the field before coming to final decision. Mason and Shepherd can protect their interests by patenting their ideas and software. Hence, it is unreasonable to expect VCs to sign this disclosure agreement. Another important fact is that legitimacy of the company that has yet to become a legal entity. Thus, any legal non disclosure agreement becomes null and void and it is highly unreasonable on the part of Mason and Shepherd to expect their venture capitalists to sign such agreement. Answer 3 Yes. Mason and Shephe

Hart's Thesis and MOMJ Perspective on Law Society Essay

Hart's Thesis and MOMJ Perspective on Law Society - Essay Example Hart (1994) further argues that because the society accepts the legal rule as the standards of judging, criticizing and even giving punishments when some members deviate, the legal rules are obligatory and all the members of the society must comply with their provisions. According to Hart, it is important for the societies to establish reflective attitudes based on common standards to ensure conformity with regard to the application of the law. In this context, Hart’s thesis that the validity of laws depend on the sources as opposed rather than its merits is significantly crucial since it can be used to solve the potential conflicts between successive norms and the concurrent rules that tend to affect various legal systems. Consequently this perspective considerably enhances the legal understanding of law making processes. Hart’s thesis is also based on the assumption that not every member of the society is expected to accept the stipulated rules as the only criteria of legal validity but rather most of the ordinary people do not often fully comprehend the legal structures as well as how to measure their validity(Hart, 1994). On the other hand, the myth of moral justice postulated by Rosenbaum suggests that the current legal system is not morally ideal because it is so formulaic and rigid that it is almost impossible to achieve just outcomes from it. In â€Å"the myth of moral justice,† Rosenbaum disagrees with Hart’s theses as well as the theories of legal positivism’s reasoning that the validity of the legal processes is always a function of the particular social systems that regulate the behavior of the members of the society. According to Rosenbaum (2004), not all of the legal cases in the courts can be simply addressed through monetary compensation and punishments as seen in most of the current legal systems. This is because sometimes the victims may only need restorative and spiritual remedies to help them achieve justic e. For example, victims of injustices should be given opportunity to express their feelings and get consolations or apologies from the parties that may have offended them. Instead most of the current legal systems are filled with moral complexities that often make it impossible to deliver justice to the members of the society. For instance most people continue to lie under the oath and this has resulted in the loss of faith and frustrations with our current justice and legal systems. Rosenbaum also challenges the contemporary training of layers particularly with regard to ethics. For example he argues from law schools to their places of career practice, lawyers are always filled with the concepts of unemotional evaluation of facts and details of cases with little regard to moral sense. Throughout the book, there are also a number of instances in which relatively simple cases ended with outcomes that are legally justified and yet are not making any moral sense. Some of the notable ca ses included the famous Nuremberg trials which ended in the acquittal of all the police officers who were charged with murder. Similarly, there are also a number of cases cited in the book where by an action that is morally sensible may not be legally acceptable for example it may be ethically
