The Pros and Cons of Science Inventions Essay Example

The Pros and Cons of Science Inventions Essay We should look at both sides of the coin. So I am writing to discuss the pros and cons of science and invention. First of all, with science and invention, there will be less work for human to do. Also, it will be more effective in doing some complicated work. This makes humans lives more enjoyable. Vacuum cleaner Is a good example, it can remove dirt and dust from the floor, and It Is very helpful for housewives. Vacuum cleaners are also Important to those who suffer from allergy ND asthma, because high- temperature vacuum can sterilize bacteria while working. Furthermore, with scientific Invention, we can discover new treatments for diagnose problems. For example, for those who suffer from diabetes- a disease which Is becoming Increasingly common, now have access to very accurate blood glucose monitoring technology. This means that they can monitor on a dally basis and control their condition much more effectively, sharply reducing the risk of blindness and nerve damage. However, there are, of course, some disadvantages along with the development of science and invention. Inventions are not always good. Sometimes, they may make people become lazier and less capable of doing things for themselves. This is because they rely more on machines and products. Nowadays, many people are addicted to computers and mobile phones.

Also, they dont know how to solve problem on their own. If they look at the screen for a long time, they will get short-sighted, too. Another important argument is that science invention may be used to create some dangerous weapons and bombs that is harmful to the society. They can kill people and cause environmental destruction. For example, the atomic bombs that were dropped on Hiroshima and Nagasaki at the end of World War II had caused a great damage to the people and environment there. Taking both the pros and cons into consideration, I think that science and invention are not always good, and we should not rely too heavily on them. But if we make good use of them, they can still help us a lot and create a more convenient life for us. The Pros and Cons of Science Inventions By Yin Wing-Lee complicated work.

10 Fascinating Praying Mantis Facts

10 Fascinating Praying Mantis Facts The word mantis comes from the Greek mantikos, for soothsayer or prophet. Indeed, these insects do seem spiritual, especially when their forelegs are clasped together as if theyre in prayer. Learn more about these mysterious insects with these 10 fascinating facts about praying mantids. 1. Most Praying Mantids Live in the Tropics Of approximately 2,000 species of mantids described to date, almost all are tropical creatures. Just 18 native species are known from the entire North American continent. About 80% of all members of the order Mantodea belong to a single family, the Mantidae. 2. The Mantids We See Most Often in the U.S. Are Exotic Species Youre more likely to find an introduced mantid species than you are to find a native praying mantis. The Chinese mantis (Tenodera aridifolia) was introduced near Philadelphia, PA about 80 years ago. This large mantid can measure up to 100 mm in length.  The European mantid, Mantis religiosa, is pale green and about half the size of the Chinese mantid. European mantids were introduced near Rochester, NY nearly a century ago. Both the Chinese and European mantids are common in the northeastern U.S. today. 3. Mantids Can Turn Their Heads a Full 180 Degrees Try to sneak up on a praying mantis, and you may be startled when it looks over its shoulder at you. No other insect can do so. Praying mantids have a flexible joint between the head and prothorax that enables them to swivel their heads. This ability, along with their rather humanoid faces and long, grasping forelegs, endears them to even the most entomophobic people among us. 4. Mantids Are Closely Related to Cockroaches and Termites These three seemingly different insects – mantids, termites, and cockroaches – are believed to descend from a common ancestor. In fact, some entomologists group these insects in a superorder (Dictyoptera), due to their close evolutionary relationships. 5. Praying Mantids Overwinter as Eggs in Temperate Regions The female praying mantis deposits her eggs on a twig or stem in the fall ​and then protects them with a Styrofoam-like substance she secretes from her body. This forms a protective egg case, or ootheca, in which her offspring will develop over the winter. Mantid egg cases are easy to spot in the winter when leaves have fallen from shrubs and trees. But be forewarned! If you bring an overwintering ootheca into your warm home, you may find your house teeming with tiny mantids. 6. Female Mantids Sometimes Eat Their Mates Yes, its true, female praying mantids do cannibalize their sex partners. In some instances, shell even behead the poor chap before theyve consummated their relationship. As it turns out, a male mantid is an even better lover when his brain, which controls inhibition, is detached from his abdominal ganglion, which controls the actual act of copulation. But most instances of sexual suicide in mantids occur in the confines of a laboratory setting. In the wild, scientists believe the male partner gets munched on less than 30% of the time. 7. Mantids Use Specialized Front Legs to Capture Prey The praying mantis is so named because when waiting for prey, it holds its front legs in an upright position as if they are folded in prayer. Dont be fooled by its angelic pose, however, because the mantid is a deadly predator. If a bee or fly happens to land within its reach, the praying mantis will extend its arms with lightning quick speed, and grab the hapless insect. Sharp spines line the mantids raptorial forelegs, enabling it to grasp the prey tightly as it eats. Some larger mantids catch and eat lizards, frogs, and even birds. Who says bugs are at the bottom of the food chain?! The praying mantis would better be called the preying mantis. 8. Mantids Are Relatively Young Compared to Other Ancient Insects The earliest fossil mantids date from the Cretaceous Period and are between 146-66 million years old. These primitive mantid specimens lack certain traits found in the mantids that live today. They dont have the elongate pronotum, or extended neck, of modern-day mantids and they lack spines on their forelegs. 9. Praying Mantids Are Not Necessarily Beneficial Insects Praying mantids can and will consume lots of other invertebrates in your garden, so theyre often considered beneficial predators. Its important to note, however, that mantids dont discriminate between good bugs and bad bugs when looking for meals. A praying mantis is just as likely to eat a native bee thats pollinating your plants as it is to eat a caterpillar pest. Garden supply companies often sell the egg cases of Chinese mantids, touting them as a biological control for your garden, but these predators may do as much harm as good in the end. 10. Mantids Have Two Eyes, but Only One Ear A praying mantis has two large, compound eyes that work together to help it decipher visual cues. But strangely, the praying mantis has just a single ear, located on the underside of its belly, just forward of its hind legs. This means the mantid cannot discriminate the direction of a sound, nor its frequency. What it can do is detect ultrasound, or sound produced by echolocating bats. Studies have shown that praying mantids are quite good at evading bats. A mantis in flight will essentially stop, drop, and roll in midair, dive bombing away from the hungry predator. Not all mantids have an ear, and those that dont are typically flightless, so they dont have to flee flying predators like bats.

How Journalism has changed from the 20th to the 21st century Research Paper

How Journalism has changed from the 20th to the 21st century - Research Paper Example Fast forward to the 21st century and news reporting has taken a completely new direction as more individuals are becoming aware of the world`s situation with all these events occurring such as catastrophes and political dynamics. It is very evident with more and younger people getting involved in the journalism and mass communication industry. The 24-hour news cycle was introduced to keep people informed of events at all times. Nowadays, there are stations such as CNN (Henderson 259), which solely report any occurrences that might happen. It is good since people are well informed on everything as it happens. However, some reporters share their information without having any facts to backup their claims. This 24-hour news cycle has given rise to institutions such as blogs (Macnamara 249) that deal solely on gossip and slander. They do not care if the readers or viewers believe them or not, their sole priority is making money, and they do not care if the stories they air or publish are damaging to some people. Recently reporters have taken as interest in speculating rather than reporting facts. It is because people want news that will interest them and not sitting on the couch and enduring two to three hours or boring and poorly produced news bulletins. That is why gossip sites and blogs such as TMZ are among the most beloved by the world over because they report both serious events as well as the amusing occurrences. They also encourage anyone with anything to share, can post their stories or videos on their website. This mode of reporting has its advantages and disadvantages. One advantage is that people can share their stories with everyone in the world while the downside is that there is no privacy in their reporting and the stories are poorly done since it takes time to verify if the stories told are merely fabrications, speculations or hard, irrefutable facts. Nowadays people are more informed than they were back in the 20th

Law Case Analysis Essay Example | Topics and Well Written Essays - 2250 words

Law Case Analysis - Essay Example The House of Commons can implement the judgement at its level. Considering the case of Spiliada Maritime V. Cansulex, the house of commons did not fully give a satisfaction to the defendant thus the defendant went ahead and made an appeal given by Lord Goff where He made a ruling that, there was enough natural form including applicable law relating to the matter, availability of witnesses, presence of the residence of the two parties and that the plaintiff had a possibility of obtaining foreign jurisdiction. Thus, there was making of a judgement by the Supreme Court. In this case, there is a judgement considering that there is no other jurisdiction that suits the requirements of the parties. The procedure the court follows includes; granting the basic principle when there is enough satisfaction by the court that there is another forum that can settle the dispute forum of the parties thus applying more suitably to the satisfaction of the parties. The court then determines the legal bu rden of proof which shows enough evidence. The Supreme Court then determines who lies with the burden depending on the existence of a natural or a forum which is appropriate. After this, the court finds the factors that show there is the existence of another forum which entails the presence of enough witnesses as well as the law that will be under administration in settling the dispute. At this moment, the court will get to a conclusion as to whether another forum is available. If there is another forum, the court then grants a stay considering the circumstances surrounding the dispute as seen in the ruling of Lord Goff1. Factors that the court takes into consideration and illustrative cases In relation to the forum non conveniens, its appropriateness is brought to question and also the applicability of the principle of forum non conveniens. This relates to cost, the outcome as well as the delays in the implementation of the principle. The principle finds its application in internat ional law especially in the private section. Its long process of implementation makes the principle to be in use in the domestic system, which involves cases where the judicial structure does not have a structure that has unification and where the judicial system is federal. The uncertainty of the outcome is due to the expansions in the level of jurisdiction in the legislation where plaintiffs can file a suit at their residential places. According to the code of civil procedure, there should be the filling of suits in the residential place of the defendant rather than that of the plaintiff. There are many details in this system due to the fact that the defendant will not accept the filling of the suit to take place at the residence of the plaintiff; this is because it may be taken as a weapon of harassment forcing the defendant to go to the residence of the plaintiff which may be far. Further, many past judgements have taken effect thus the court may have a challenge in deciding whi ch is the best channel to solve the dispute amicably thus leading to delays. There are enormous costs from the implementation of this principle where, the defendant and the plaintiff may face off due to the fact that they have the right for the cases to be heard at the place due to the cost as well as moving there witnesses to the residence

Life in the 13 Original Colonies Essay Example for Free

Life in the 13 Original Colonies Essay In the 1600’s and 1700’s, the economies of the northern and southern colonies were affected due to many different factors. Because of the different climates and geography of their land, the northern colonies and southern colonies had different resources available to them, which shaped their societies into what they are today. The resources available to the northern colonies were completely different from the resources that were available to the southern colonies. In the northern colonies, due to the climate and geography of their land, crop growth wasn’t as successful as it was in the south. The could weather and rocky land made it hard for them so as time went on, the northern colonies became more of an industrial people and relied more on manufacturing things like naval equipment and rum. A few of the northern colonies participated in what they called a triangular trade system where New England traded rum for slaves from Africa and then these slaves were given to the west indies in exchange for sugar and molasses, which was made into rum again. The northern colonies heavily relied on this system and it was this that brought New England success. In the south, the climate was mainly warm and perfect for crop growth so the southern colonies became more agricultural. The main reason the south had such great success in the area of crop growth was because they discovered a great cash crop called tobacco. Due to it’s addictive nature and great taste, the demand for it was very high. The south purchased tons of slaves because farmers relied on slavery to help the success of their farms and crops. They were different from the northern colonies in this way because the north rarely used slaves. They merely transported them. Education was strongly affected by the geography and climate also, believe it or not. The North was cold and hard to grow crops in so they were more industrial based. This meant that all of the people needed to know how to read and write in order to make deals with the other nations. In the northern colonies, there were very few public schools. Therefore, the parents of children usually just hired a tutor until they went off to a university. If the family couldn’t afford a tutor, then they either sent the child to a public school, or didn’t educate them at all. In the south, the climate and geography was perfect for growing crops. Therefore most people lived on large farms called plantations. There was less emphasis on education in the south because most of the people were  slaves or indentured servants. Also, even many of the landowners didn’t know how to read or write because not much is needed to know in order to farm and they didn’t have to worry about trading overseas. They left that to the north. Ultimately, the geography and climate of the northern and southern colonies was the main factor that shaped the societies into what they are today. For instance, the north had horrible luck in climate for crop growth, which made them more of an industrial group of settlers. The south thrived on crop growth, which made them more of an agricultural group of settlers.

Media and Moral Panic

Media is the main revenue of mass communication. The media plays a variety of roles in society; its main responsibility is that of providing information. As constant consumers and users of this information the relevance to the majority of members in the wider community inclusive of teachers and students is critical. The media positions us as the audience to take a particular viewpoint of a topic, issue or problem that is evident in our society.To what extent though does this role as information provider influence moral panic? Moral panic refers to the exaggerated social response to media coverage of a sporadic episode that consequently turns it into a widespread issue and causes colossal concern in society (Cohen, 1987). The media has a tendency to manipulate people by amplifying the facts and truths and using multiple camera techniques to surround a group/individual and outcast them in society, thus labeling them the ‘other’. Othering’ is closely linked to discri mination as it consists of the â€Å"objectification of another person or group† which puts aside and ignores the complexity and subjectivity of the individual/s. Teachers and students must construct their own knowledge about media coverage and understand that at times the media amplifies issues of concern by stereotyping and excluding particular members of society. A certain structure exists in society, if groups/individuals step outside of the boundaries, society categorises them as ‘others’ and excludes them from the majority.After this occurrence there are two options that exist; to either accept the exclusion or conform to societal norms and return to the inclusion. It is vital to understand the effect that bullying, discrimination and the mass media have on these groups/individuals and realise that some students in your classroom may fall under these categories. Therefore it is in our power as teachers, to inform and position students to be critically liter ate consumers of the media, to ensure they are able to bestow a critical perspective towards texts.Due to the fact that the media plays a massive role in students’ everyday lives in the 21st century it is vital that educators engage students in pedagogical experiences that teach them to become critically literate readers. Students could start by developing an understanding of the indicators of moral panic which are: 1. Concern – the issue is at a sensitive level and affects one’s feelings on a personal level. 2. Hostility – increased level of antagonism towards those involved in the threat or panic. 3. Consensus – a general agreement among society that a threat actually exists. . Disproportionality – the problem is exaggerated and amplified to create public concern. 5. Volatility – erupts suddenly and almost as quickly then subsides or disappears. (Goode & Ben-Yehuda, 1994). Developing an understanding of these indicators gives studen ts a solid foundation to be able to critically analyse the texts they observe and hear to make an informed decision about the information they are receiving. Students must also have an understanding of the indicators of Disproportionality so they are able to critically analyse the texts they are viewing.They must be able to identify when figures are exaggerated, figures are fabricated altogether, where there are other harmful conditions in society but they are not getting mass coverage and the changes over time (Critcher, 2006). It can have a detrimental effect in students understanding if they are not presented the tools to be critical readers of texts. In conclusion, it is completely important and relevant to teachers and their students to have a critical understanding of the relationship between the media and moral panic because†¦.
