Arthropoda :: Biology Anthropods

Arthropoda Arthropods are animals belonging to the phylum Arthropoda, which is the largest of all phyla in the Animal Kingdom, with more than one million species, making them almost 80% of the whole kingdom. These include insects, arachnids, crustaceans and many more, most of which are quite small, the biggest being the Japanese Spider Crab with a leg span of 3.5 meters and the smallest being the microscopic Plankton. *Characteristics: - Segmented Body. - Exoskeleton. This is a hard outer body covering which protects the internal organs. - Jointed legs. The name ‘arthropod’ comes from Latin, meaning ‘joints’. - Specialized mouth parts. - Compound eyes. - Nervous system consisting of a brain. - Sexes mostly separate. - An open circulatory system. *Classification: Subphyla: Arachnida is a subphylum of Arthropoda, consisting of over 100 000 species, many of them being parasites which can carry disease. They are found in all environments, and mostly have eight legs, which is a feature, together with the fact that they do not have wings or antennae, often used to distinguish them from the other subphyla, though there are exceptions. They include spiders, scorpions, ticks and mites. Their bodies are divided up into three parts: the cephalothorax, the opisthosoma and the thorax, and use a type of lung for gas exchange. Most Arachnids are carnivorous, and eat pre-digested insects and other small animals. They reproduce using internal reproduction usually lay eggs, except for the scorpion which bears living young. The word ‘Arachnid’ comes from the Greek word ‘Arachne’ meaning ‘spider’. Crustacea is a large subphylum of Arthropoda, consisting of almost 52 000 described species, including animals like crabs, lobsters, shrimp and barnacles. The majority of these are aquatic, living in marine or fresh water environments, though some have adapted to living on land like some crabs and woodlice. Most crustaceans are relatively small, though there are some exceptions. All of them have a hard, strong exoskeleton, divided into two parts, which has to be shed in order to allow the animal itself to grow. They have a large circulation system, where blood is pumped around the body by the heart. Only some crustaceans have sexes separate, and those that are usually mate seasonally and lay eggs. The study of Crustacea is called carcinology. Diplopoda is a class, belonging to the subphylum of Arthropoda Myriapoda, consisting of about 10 000 species of animals which have two pairs of legs for each body segment and are often known as Millipedes. Hence the name, they do not have one thousand legs.

Analysis essay of the film “Falling Down” Essay

The film Falling Down is about a man named Bill that loses control of his anger and frustration when confronted with typical everyday stress. He has reached his breaking point and loses his cool as well as his sense of self. The movie demonstrates examples of both cultural and social issues. Cultural issues explored by this movie are the existence of subcultures and countercultures in city life. The movie takes place in Los Angeles, California that is largely populated by Mexicans and Oriental migrants. The protagonist, played by Michael Douglas, encounters and oriental man that owns a local mini mart and two Mexican gang members. The oriental man represents the subculture and the gang members represent the counterculture. The social issues are reflected through gender relations, racial relations, and anomie, as well as traffic and violence. This film has great emphasis on the social aspect. The film places these factors in the context of a social setting with cultural influences. Social stratification plays a minor role in this movie. The only valid example of it is in the scenes involving the police officers. There is a rank system within the field of police work and the particular ranks are respected. Gender roles play a somewhat larger role within the context of the main character. There is a moderate amount of interaction between the protagonist and his ex-wife. However, the communications between them is brief and tense. The ex-wife fears him because of his uncontrollable temper. Bill, however, speaks to her under the disillusion that they are still a family.

The first meeting is between the protagonist and the oriental man that owns the local mini mart. After abandoning his car in a traffic jam. Bill goes to the payphone to call his wife. He realizes that he doesn’t have enough change and goes to the mini mart to change a dollar bill. The oriental man tells him he must make a purchase in order to get change. He opts to buy a coca-cola. The oriental man tells him the coke will cost him $0.85. Bill is very disturbed because this will not give him enough change to make the phone call. He feels cheated because a foreigner is overcharging him to buy American goods. At the end of the scene, he has his first outburst and damages many of the  goods and products and then buys the soda at a reasonable price. This scene also illustrates the main characters current social role as a consumer. The next meeting is with the Mexican gang members who threaten him in the name of territory. They look and communicate differently not only because they are Hispanic, but because they have their own internal communication system within the gang members. He uses the wooden bat that he took from the mini mart to physically defend himself against the gang members. The scene contains his second outburst. The film takes place in a city much like Miami. The mood in the metropolitan city is very busy, fast-paced, defensive, and stressed. The film opens in a scene where the protagonist is â€Å"trapped† in his car while stuck in traffic due to road construction. This is very typical of life here in Miami. The issues raised by the film are relative to the Miami lifestyle. Many of us can relate to the frustration we feel when stuck in traffic caused by roadwork during rush hour. We can also relate to the volume of shops and restaurants owned by foreigners and the ever -growing concern with inflation. This film seems to have been designed to entertain viewers. Nevertheless, it has some key social elements that express to the viewer about the sociology of urban life. This film encourages critical thinking to those who are willing to study this film for its true social value. Unfortunately, most people view this film for entertainment purposes and do not make the time to read into it. It seems that the overall public reaction is that this movie reflects the social nor, and that it will be accepted as such. Within that state of mind, people would see the film as a reflection of modern times and not wonder, â€Å"What we can do about it?†

The rise of integrated reporting and increased investor focus on extra-financial factors are part of a new global attitude toward business. One example of this trend is provided by research from Ceres, an advocacy organization for sustainability leadership, into the evolution of sustainability practice in companies (Ceres, 2014; Ceres & Ramani, 2015). To understand what makes some companies more useful when it comes to delivering sustainability performance without sacrificing mission, Ceres focused its studies on how boards and directors provide oversight for sustainability. Their research discovered that by making both executives and governing boards formally accountable for sustainability performance, organizations can face the increasing pressure to deliver on sustainability and maintain social mission. Governance practices can provide a framework for building mission into the DNA of organizations. To take this inquiry further, more research is needed to capture current learning across sectors and to identify mission-supportive governance practice as it evolves. Sharing this information with budding social entrepreneurs, MBA students and investors, to increase their understanding of governance as a solution to mission challenges, could help develop more sophisticated attitudes toward the role of governance across the sector. Additionally, more research into Mission monitoring that makes use of metrics and enables governing boards and managers to evaluate mission alongside financial performance and deliver oversight and accountability in both areas is needed. Investor engagement is another area where more research could be beneficial. As the sector continues to expand into the mainstream, new investors will be joining the boards of growing social entrepreneurships and exerting their influence. More work on how the leaders of these organizations can create proactive strategies to identify investors who align with the mission and negotiate favorable terms for mission preservation would be welcome. More research into how investor behavior, and the impact that has on mission preservation, could yield clues as to why so many businesses find mission pushed to the margins as they grow. There is also room for developing practical resources to help social entrepreneurships establish effective investor engagement and communication strategies. As the sector matures, finding the right people remains challenging for organizations in the hectic scaling stage. More extensive use of skills matrices—and matrices developed especially for mission-driven businesses—could help. A specialist referral service, online skills bank or recruiting agency could be established to connect organizations with appropriate candidates.

Fiction Paper - The Yellow Wallpaper By Charlotte Perkins Gilman Essay

Fiction Paper - The Yellow Wallpaper By Charlotte Perkins Gilman - Essay Example At the end of the story, the woman is seen creeping around the walls of the room, after having torn away the wallpaper as high as she can reach, seeking a way of entering their world or releasing them from the walls where they used to hide. While the story is not necessarily intended to be understood as a ghost story, instead addressing the very real mental conditions that can be and were forced upon women in particular as a result of their constraints within society, it can be understood from a supernatural perspective. Reading this story from a realist perspective, the woman slowly loses her sanity as a result of her inability to conform to societal norms. At every stage of her illness, it can be seen that the husband has little understanding of how she feels and little regard for her own input regarding what might help her. He looks at the world from a very scientific perspective and is incapable of moving beyond the hard facts to consider his wife’s emotional needs. The couple takes up residence in an upper room of the house, thought to have once been a nursery, with bars on the windows and old faded yellow wallpaper attached to the walls. This wallpaper plays a large role in the progression of the woman’s illness as she begins to see women creeping around inside it, trying to escape the oppression they, too, have experienced. In the end, the woman is completely insane, creeping around the walls herself after peeling the wallpaper off as high as she can reach, even creeping over he r husband, who has fainted against the wall, in order to continue her progress unimpeded. Although she realizes there is something wrong with her, she writes that the men of her world, her husband and her brother who are both physicians, do not agree that she is sick, describing her condition as being a â€Å"temporary nervous depression – a slight hysterical tendency† (Gilman, 1899).

The Economic Dragons Threatening Our World Research Paper

The Economic Dragons Threatening Our World - Research Paper Example Offhand our exercise looks easy, but it is not, and this judgment has less to do with the dearth of facts than with the basic givens. â€Å"A rich East Asian nation with a pegged currency fixed to the US dollar for ten years, supported by a monetary policy of tight capital outward flows and unrestricted inflows is experiencing an upward pressure on the exchange rate.† The question remains: what to do now? Deciding on a strategy depends on a clear understanding of the world’s monetary system, the role that exchange rates play, how they are determined, and what will happen if we do nothing. As Robert Solomon said (1977, cited in Samuelson, 1992): The world’s monetary system is like the traffic lights in a city, taken for granted until it begins to malfunction and to disrupt people’s lives†¦A well-functioning monetary system will facilitate international trade and investment and smooth adaptation to change. A monetary system that functions poorly may not only discourage the development of trade and investment among nations but subject their economies to disruptive shocks when necessary adjustments are prevented or delayed. The world’s monetary system refers â€Å"to the set of policies, institutions, practices, regulations, and mechanisms that determine the rate at which one currency is exchanged for another† (Shapiro, 1996). It is the coordinated way each nation manages its supply of money so that we can buy and sell each other’s goods, doing business by exchanging pieces of paper, the value of which we agree on called money.

21st Century Women's Health Act of 2015 Research Paper

21st Century Women's Health Act of 2015 - Research Paper Example According to Senator Murray, women living in the US are at a precarious situation as far as their reproductive health is concerned. Regardless of the fact that Obamacare has significant increased access to affordable health services that are gender based, conservative politicians from the entire nation have been persistently campaigning at the state and federal level with the aim of overturning the law that safeguards the healthcare rights of women, and they have been successful in some occasions. She further states that there has been significant progress in regards to advancement of the health of women and expansion on access to reproductive care, but there is still a lot of work that has to be done since some of the elected officials are determined to reverse the laws already created. Therefore, it can be considered that the 21st Century Women’s Health Act proposes essential means of moving forward in regards to the health of women. This new law emphasis on a number of key aspects in terms of the health care of women including their maternity services, offering support for victims of rape and sexual assault, contraception, reproductive rights, abortion as well as preventive care. Eight months after she unsuccessfully attempted to override the decision of the US Supreme Court on contraceptive coverage, Senator Patty Murray came out with another proposal that sought to safeguard access to reproductive health services by women. This wide-ranging bill will obligate the state Medicaid programs to provide comprehensive coverage for all types of birth control, necessitate hospitals to avail free emergency contraception to sexually assaulted patients while at the same time ordering studies on the manner in which state enact laws to limit access to abortions as well as other family planning methods and services. This bill seeks to reverse the laws that are considered by Senator Murray to be taking the nation backwards and dealing with the officials who are
