Picture of the Agar Plate After 3 Days Questions Exercise 1: Microscopic Anatomy of Lymphatic Structures A. How are lymph, lymphatic vessels and lymph nodes related? Lymph, lymphatic vessels and lymph nodes are all part of the lymphatic system. Lymph vessels carry lymph throughout the body. Throughout the vessles are lymph nodes which fight infection. B. What are the two major functions of the lymph nodes? They clean and filter lymph before it goes back to the blood. They produce antibodies and lymphocytes. C. What are the two functions of the spleen? It protects the body and helps to produce and store blood cells. D. What is the function of the tonsils? They protect the body from harmful germs. E. What are the structural similarities found in lymph nodes, spleen and tonsils? They all have a capsule and are rounded organs with an internal parenchyma of lymphoid cells. Exercise 2: Immunity and the Immune Response A. Explain what is meant by â€Å"memory† as a characteristic of the immune response. When the body comes in contact with a harmful antigen, it has a primary response, which remembers the antigen by creating memory cells. By the secondary response, the memory cells will counteract the antigen. B. How does our immune response distinguish between our own cells and foreign invaders? A major histocompatibility complex is at the surface of each cell in our body. It is what recognizes if something is foreign or not, and lets the immune system know. B. What are lymphocytes and where are they produced? Lymphocytes are a type of white blood cell that protect the body from infection. They are produced in the bone marrow. C. Distinguish between an antigen and an antibody. An antigen is a foreign material that enters the body, and an antibody is what recognizes the foreign material and helps fight it.

Social Problems of Ecstasy and Raves Throughout American history drugs have posed a problem to society and lawmakers. Many attempts have transpired to try to prevent future problems associated with drugs. Many of the drugs threatening America were originally designed toward the improvement of human health. The most recent epidemic of recreational drug use is ecstasy. Ecstasy’s popularity is particularly in the possession of the nations youth. The institute of use is at all-night clubs and bars within many large cities. Recent research has been completed about the problems and long term effects of the drug. Does the new era of rave clubs and club drugs such as ecstasy pose a great threat to society? Before analyzing the societal problems associated with ecstasy it is important to understand what it is and its background. Ecstasy or MDMA (methylenedioxmethamphetamine) first originated in 1914 and was used as an appetite suppressant; it was not heavily used again until the 1970â €™s and was used to treat psychological disorders. Finally in the 1980’s the drug administration banned any open use of ecstasy because of recent test results proving it causes health problems. Recently the drug has become very popular and the rising popularity is from the influence of the rave movement. Boom, Boom, Boom. The sound of the new innovative music, responsible for cultivating and transforming society erupts from the speakers of a rave. Codes of conduct at raves are nonexistent. With out rules the crowds are encouraged to participate in whatever they find pleasing. People attend the raves to dance, but in actuality the ravers seek thrill through clandestine actions. Raves usually are praised for creating peaceful and positive vibes, but in spite of the fun and happiness created, raves also have many downfalls. Raving is an all-night activity. Large quantities of "rave kids" use mind and body altering drugs enabling them to indulge in a night of dancin g and immoral behavior. Ecstasy is a quintessential part of entertainment at the rave scene. The drug enhances the scene and the raver does not fully appreciate the moment unless in an altered state of mind. Kids who use ecstasy roam around the scene lost, and not in touch with reality. The ravers are experiencing the moment, but to others it sounds as if they are experiencing mass confusion. Some "ravers" consider alcohol to be a â€Å"square† drug, and therefore seek an alternate source of synthetic energy, such as ecstasy.

Holistic/Direct Observation/Witness Statement Professional Discussion Essay

Outcome 1.1: How do you review the range of individuals and groups in your workplace whose communication needs must be addressed? As an assistant manager I have a responsibility to my residents, to accommodate, and provide support for all residents, and their individual communication needs. By performing assessments with individual residents, I am able to understand the problems they have with communication, and actions and aids we can supply, to enable them to communicate effectively. In assessing communication needs, I need to consider each individual, and cater for the individual’s needs. I need to consider ‘groups’ of individuals, for instance males/females, foreign speaking users, deaf/Blind users etc. The actions and aids we supply for communication needs should benefit not just the individual, but the group of service users as a whole, and encourage interaction, inclusion, and social contacts. Regular reviews should be performed to ensure individual needs are being met and I do this during my 3 monthly care plan reviews. Outcome 1.2: Explain how you support effective communication within your job role To support effective communication within my job role I encourage the staff and clients to discuss any concerns or suggestions they may have to improve the care and service we provide. This Is done through supervisions/appraisals and we also give the staff the opportunity to make suggestions in our staff meetings. Staff are encouraged to put any points they would like to raise in writing and hand to myself or the manager for team discussion at the meeting. Our clients have the opportunity to raise any issues or concerns at the resident meetings that are held every two months, and also via their keyworker on a monthly basis. Staff and clients are also able to discuss any issue in confidence with myself or the manager in private. Outcome 1.3: Explain how you analyse the barriers and challenges to communication within your own job role. There are several barriers that may affect the flow of communication. These barriers interrupt the flow of communication from the sender to the receiver, thus making communication ineffective. It is essential for managers to overcome these barriers. The first barriers to check out are those that an employee could be creating. People may think that they are doing everything possible to assist communication, but they should make sure that they are not making it difficult for people to understand what they say for instance using abbreviations another person does not understand. People should avoid professional jargon and terminology. Also to speak as clearly as possible and repeat themselves if necessary. Someone with a strong accent may find it increasing difficult to make themselves understood. Physical barriers – these are due to the nature of the environment where people are trying to communicate. It could be there are distractions or noise, such as the TV on or interferences from a loudspeaker. Other problems may be caused by faulty equipment and it is important to check things such as hearing aids on a regular basis to make sure they are working effectively. Outcome 2.1: Explain how you monitor the effectiveness of communication systems and practices in your work place. This is monitored through supervision and appraisal, quality assurance survey, daily reports and handovers. Outcome 2.2: Explain how and why you should evaluate existing communication systems and practices We evaluate by communicating on a regular basis with staff and clients through meetings and informal chats to make sure systems and practices are working effectively. This is important to maintain a high standard of communication and care, and to minimise the risk of important information being lost or overlooked. Outcome 2.3: What improvements would you propose to put in place for the communication systems and practices used which will address any shortcomings? I would propose regular training updates for staff and maintain a close working relationship with our local gp’s and district nurse team to keep informed of any changes on either side. Outcome 3.2: How do you compare the effectiveness of different communication systems for partnership working? Effective partnership working is built upon a clear understanding of the different roles each person has in supporting the client. Increasing clarity and agreement about roles and responsibilities improves understanding, and leads to mutually supportive relationships. We compare the effectiveness by keeping open close lines of communication with all agencies that maybe involved in an individual’s care and relaying appropriate information to those involved. We also send out annual quality assurance surveys to all agencies we work with and the families of our clients. Collating or collecting information is essential in monitoring the effectiveness of the  communication systems. We can collect the information observing, getting feedback from others and recording information. So we need to work with others to identify ways to support the continued development of communication. Care professionals communicate with colleagues and other professionals in many contexts every day. Effe ctive communication requires personal and professional respect for others, trust in the judgement and values of colleagues, good verbal and listening skills. Outcome 3.3: What improvements would you propose to make improvements to communication systems for partnership working? I would propose a main point of contact for each team involved and regular group meetings to discuss issues that may arise, also regular feedback sessions to ensure we are working together effectively. Outcome 4.1: Explain legal and ethical tensions between maintaining confidentiality and sharing information. This arises when you feel someone in your care maybe suffering from some form of abuse from either a family member or member of staff or they have told you something in strict confidence. You have a duty of care to protect the individual but the tensions may arise if the client has told you something in confidence but you feel action needs to be taken and you have to pass sensitive information to a third party. Outcome 4.2: What are the essential features of information sharing agreements within and between organisations? Information needed for the safety and wellbeing of a client should only be passed on to outside agencies after consultation with the client and only after their consent has been obtained. Information should only be shared on a need to know basis and total respect must be given to confidentiality regarding all aspects of a client’s care.

Mr. Robert Worstell s Invisible Man - 1937 Words

Jordan Welty Mr. Robert Worstell AP Literature and Composition Wednesday, August 26, 2015 In all stories, novels, and plays, cultural, physical, and geographical surroundings not only affect the plots of literature, but also shape psychological and moral traits in all characters. Pauline Hopkins said in Contending Forces, â€Å"And, after all, our surroundings influence our lives as much as fate, destiny, or any supernatural agency.† This can be seen in Ralph Ellison’s Invisible Man. In the prologue of the novel, the narrator immediately tells the reader that he is an invisible man, but he is not talking about physically. He states, â€Å"I am invisible, understand, simply because people refuse to see me. That invisibility to which I refer occurs†¦show more content†¦I never told you, but our life is a war and I have been a traitor all my born days, a spy in the enemy’s country since I give up my gun back in the Reconstruction. Live with your head in the lion’s mouth. I want you to overcome ’em with yeses, undermine ’em with grins, agree ’em to death and destruction, let ’em swoller you till they vomit or bust wide open. Learn it to the younguns,† (Ellison, page 16). These words had an impact on the narrator all throughout his life and led to him accepting his invisibility at the end of the novel. When the narrator was a junior in college, he had his first experience with betrayal. He was asked to drive a wealthy white trustee of the college named Mr. Norton around the campus. Mr. Norton asked the narrator to drive him to the old slave quarters, where he meets a sharecropper named Jim Trueblood. After listening to Trueblood talk about getting his own daughter pregnant, Mr. Norton began to feel faint and asked the narrator to get him some whiskey. The narrator took him to the Golden Day, a saloon for black people and mentally imbalanced veterans. Once Mr. Norton regained consciousness, the narrator got him back to the college and had to face Dr. Bledsoe, the president of the col lege. Dr. Bledsoe was very angry with the narrator for not showing Mr. Norton an idealized version of black life. Dr. Bledsoe lectured, â€Å"Ordered you? He ordered you. Dammit, white folk are always giving orders, it’s a habit
