Facts About the Order Cetacea

Facts About the Order Cetacea The Order Cetacea is the group of marine mammals that includes the cetaceans - the whales, dolphins and porpoises. Description There are 86 species of cetaceans, and these are divided into two suborders - the mysticetes (baleen whales, 14 species) and odontocetes (toothed whales, 72 species). Cetaceans range in size from just a few feet long to over 100 feet long. Unlike fish, which swim by moving their heads from side-to-side to swing their tail, cetaceans propel themselves by moving their tail in a smooth, up-and-down motion. Some cetaceans, such as the Dalls porpoise and the orca (killer whale) can swim faster than 30 miles per hour. Cetaceans Are Mammals Cetaceans are mammals, which means they are endothermic (commonly called warm-blooded) and their internal body temperature is about the same as a humans. They give birth to live young and breathe air through lungs just like we do. They even have hair. Classification Kingdom: AnimaliaPhylum: ChordataClass: MammaliaOrder: Cetacea Feeding Baleen and toothed whales have distinct feeding differences. Baleen whales use plates made of keratin to filter out large quantities of small fish, crustaceans or plankton from the sea water. Toothed whales often gather in pods and work cooperatively to feed. They prey on animals such as fish, cephalopods, and skates. Reproduction Cetaceans reproduce sexually, and females usually have one calf at a time. The gestation period for many cetacean species is about 1 year. Habitat and Distribution Cetaceans are found worldwide, from tropical to arctic waters. Some species, like the bottlenose dolphin may be found in coastal areas (e.g., southeastern U.S.), while others, like the sperm whale, may range far offshore to waters thousands of feet deep. Conservation Many cetacean species were decimated by whaling. Some, like the North Atlantic right whale, have been slow to recover. Many cetacean species are protected now - in the U.S., all marine mammals have protection under the Marine Mammal Protection Act. Other threats to cetaceans include entanglement in fishing gear or marine debris, ship collisions, pollution, and coastal development.

Pls see the attachment - Essay Example Steve should have set up an agenda for his day and should have had a system to organize his paperwork. Before the meeting, Steve received a call on a rush job, which he had turned over to one of his production supervisors, Lucy Adams, and put out of his mind. He tried to reach her and discovered she was out of town and difficult to reach. He asked his secretary to leave her a message to call him. He should have told his secretary to ask Lucy about the job in case he was not in the office when she called. The rest of his day was one interruption after another—an appointment not listed, a priority job his boss had asked for that wasn’t done, being late for another meeting, missing calls from Lucy—and at 4:30, he decided to go home, wondering how he could ever get caught up. It is obvious Steve Arnold is a disaster waiting to happen. He is balancing on a tight rope, and any minute he’s apt to crash. He has several employees apparently capable of handling projects, but Steve has never created a preliminary schedule that would include early morning meetings with his staff to plan not only each day but also the time lines needed to complete projects by a reasonable deadline. It would also appear that his secretary, Ruth, either has not been given the option of helping Steve organize his own scheduled priorities and putting his papers in order or she is not dependable and probably should be replaced. Steve does not look ahead to determine how to prioritize his time. He also does not look at the overall picture to see how production schedules should interact. He needs to educate himself on these matters. Steve does not appear to have much personal interaction with any of his staff nor does he schedule his time properly. He will improve greatly as a leader if he sets a preliminary schedule for his day with connections to future projects and the reminders he needs to follow up. Once he does this, he will

Commentary on a Passage from Shelleys Frankenstein :: Mary Shelley

The passage begins in first person, whom we presume is Frankenstein, where he is reminiscing on some of the consequences of his meddling with nature. He informs us that three years ago, he was engaged in an activity which created a monster whom he describes as a ‘fiend whose unparalleled barbarity has desolated my heart, and filled it for ever with the bitterest remorse.’ He then goes on to talk about how he is about to create a ‘mate’ for the previous monster and is frightened about the effects it will have on both his creation and society. The mood of the passage is very glum as the narrator is contemplating the unforeseen horrors arising from this strange experiment. He questions the result of this ‘mate’, thinking ‘she also might turn with disgust from him to the superior beauty of man, she might quit him, and he be again alone’. Through his voice, it assists our understanding of the material as through the narrator’s bleak heart, we are made to experience very strongly the extent of his guilt. The tone of this passage is somewhat personal in the sense that he seems like he is arguing and deliberating to himself about the events which either have happened or are about to, ‘ †¦Had I the a right, for my own benefit, to inflict this curse upon everlasting generations?’. He questions his own significance in society at the time when the passage is written and for the future generations and thinks himself as a ‘curse upon everlasting generations’. Having heard his reasons and seen his desolation and feeling the despair of desolation we, as readers are more able to sympathise with his actions.

The setting plays an important part in reflecting the shifting moods and emotions of characters by giving us a sense of loneliness ‘ I sat one evening in my laboratory†¦.

Amanda Bynes Psychological Perspective Essay

The popular child star, Amanda Bynes, has recently gone through a wild child phase, as seen by committing several federal crimes, such as hitting and running, driving under the influence, and using illegal drugs. Bynes has recently been diagnosed with both Schizophrenia, and Bipolar Disorder. Finally, after several outrageous months, Bynes was, â€Å"placed under an involuntary hold,† known as the 5150 psychiatric hold, in Los Angeles, California. The UCLA Medical Center came to a conclusion and diagnosed Amanda Bynes with both, a bipolar disorder, and schizophrenia. Bynes’ disorder can be applicable based on several different perspectives such as the biological, and the social cognitive. Schizophrenia is a severe psychological disorder in which the person is categorized as having disturbed perceptions, inappropriate emotions and actions, disorganized, and delusional thoughts. Schizophrenia occurs due to dopamine over activity in the brain, biological predisposition, an d environmental stresses when in the mother’s womb. Bynes biological, schizophrenic symptoms included hallucination, disorganized speech, social withdrawal, and a sense that she was not truly part of the world. Bynes also suffers from a bipolar disorder that is also a genetic predisposition and is caused by three different brain chemicals, norepinephrine, serotonin, and dopamine, and abnormal brain circuit function. All the same, Schizophrenia, and bipolar disorders can be connected based on the dopamine chemical. On the other hand, the Freudian perspective believed that schizophrenia was truly several disorders, and was probably caused by the fact that the child did not successfully develop an attachment. Due to the fact that Bynes is actually diagnosed with more than one form of Schizophrenia, and with a bipolar disorder, Freud’s belief was right. All the same it is said that Bynes suffers a slight form of posttraumatic stress disorder after going through the pressures of stardom. Bynes never truly had parental figures as mentioned by a fox news source, â€Å"Amanda can’t make important decisions regarding her finances and welfare,† explained the source. â€Å"But her parents can’t either. Everything still needs  to go through Amanda lawyer and the judge.† The Neo-Freudian perspective believed much in the Freudian perspective, but placed a greater emphasize on childhood relationships. Based on the Neo-Freudian perspective the people who developed psychological disorders such as schizophrenia were love deprived. Based on Bynes’ history, the neo- Freudian perspective would apply based on the fact that she grew up on television without living a normal life and forming normal loving relationships. Growing up in the spotlight is not so easy, as portrayed by stars like Lindsey Lohan, Britney Spears, and Macaulay Culkin. The social cognitive perspective emphasizes this point. The social cognitive perspective emphasized the importa nce of how people process information, and how they apply that information when placed in a social environment. Based on research in both schizophrenia, and bipolar disorder we see how Bynes’ has a lack of social cognition. One of the symptoms that prove the social cognitive perspective is her need to be in a rehabilitation center due to the fact that she cannot be part of community. The behavior perspective suggests that all behaviors are learned. Based on the fact that Bynes grew up in stardom several celebrities went wild. Based on the behavior perspective Bynes’ paranoid schizophrenia could have also formed from all the paparazzi bombarding her. Existential psychology uses the study of phenomena, which are our feelings, relationships, thoughts ext. Existential psychology focuses on the inner conflicts a person, has based on confrontation with the world. All the same there are two existential dilemmas that include the balance between autonomy and connection, and the need to have a sense of self-security. For bipolar as well as schizophrenics existential psychology greatly affects the person. Before being admitted into rehab, Amanda Bynes was said to be suicidal, meaning that her thoughts on he r own existentialism were extremely low. All in all, we see how all of the six different perspective of Amanda Bynes’ can be of great use when diagnosing a psychological disorder.
