Scientific Evidence Which Lead to the Fluid Mosaic Model

The scientific evidence which lead to the fluid mosaic model 19th Century: The earliest models were very simple, as they suggested that lipid soluble substances entered cells faster than water soluble substances; scientists in those days had also figured out that the layers of lipid were layers of fat. However, the downfall of the evidence provided was that scientists back in the day were not able to provide information, as to how a lipid layer could remain stable in contact with the water surrounding the cell in its environment, since lipids are repelled by water. 0th century: Due to chemical analysis of isolated membranes, it was discovered that the membrane is largely made up of phospholipids and cholesterol. Digging deeper, it was revealed that phospholipids were amphiphilic: one head, which was soluble in water, and two tails, which would face inwards towards each other. This added to the bilayer remaining stable. 1934: A new model was proposed by Davson-Danielli, since the new model suggested both sides of the bilayer to be coated with water-soluble proteins.Therefore, through extensive chemical analysis, it was revealed that there was a lot of protein in the membranes. Even though membranes were thought to be more permeable to lipids than water, the membrane was able to absorb water faster than a pure phospholipid layer. 1970: Davson-Danielli’s model and theory was still accepted, since micrographs showed that membranes had a three-layered-structure.Before the fluid-mosaic model: Due to advances in chemistry and biology, Davson-Danielli didn’t seem to explain coherently how such fluidity could occur without tearing or breaking bonds. Due to new chemical methods, it was stated that the proteins of membranes were highly variable in both quantity and type. Sixty five years later: The fluid mosaic model was invented, which described the agreement of many scientists’ view on the cell membrane.

The Problem Of Chronic Kidney Disease - 1490 Words

Introduction The United States finds itself in a challenging predicament. With the population of Baby Boomers entering the fifth and sixth decades of their lives, health care will be faced with the onslaught of chronic diseases that accompany the aging process. To combat this impending health care shift, health care is being transformed from the traditional hospital setting to more community based and long term, health care treatments/solutions. One of these diseases that plague older adults and impose a burden for the health care system is chronic kidney failure. Headley (2014), explains that chronic kidney disease (CKD) involves a progressive, irreversible loss of kidney function (p. 1107). To diagnose CKD the National Kidney Foundation states a person must have kidney damage or a decreased GFR of less than 60 mL/min/1.73m2 for longer than three months (p. 1107). CKD is underdiagnosed and untreated in the United States. This is most likely contributed to the fact that the kidneys are so adaptiv e. A patient living with CKD may not even know it, presenting with no symptoms for years. It is only untill the kidneys are considerably damaged that a proper diagnosis is often made (Headley, 2014, p.1108). Elliott (2012) explores the prevalence of chronic kidney disease in the United States. With data from the United States Renal Data System, out of the 1.2 million participants who were above the age of 65, 12,308 were diagnosed with (CKD stages 1-5) (p.4).

Addiction was the only hand he ever held, the only eyes he ever looked out of, and because of that, he never truly saw a sunset or felt a breeze on his face. It would have only taken one person to say something that could have changed the course of his life forever. There are various factors that lead me down a path of wanting to become a Substance Abuse Counselor. Don’t waste time! Our writers will create an original "AOD Counselor Job Description" essay for you Create order I felt this career choice was a way to breath new life into people and that other people’s endings won’t end up being apart of a statistics. However, this course is not black and white; it’s training to help patients with their inner demons and trying to ease the road of recovery for them. I cannot divulge that every person’s reason for drug use is because they mentally self destructed and the rest followed. Nonetheless, there had to be a moment that they no longer saw a tomorrow for themselves. Mental Health is the priority of Substance Abuse Counselors. They help people that are struggling both mentally and physically, to defeat their addictions. The route of education for a AOD counselor can be achieved by certification with counseling, gaining clinical practice hours, passing a background check, and undergoing exams for National/State licensing. Evidently, the stipulations are determined by state licensing organizations and governing boards. A two year degree like an Associate’s, is generally what is required to be equipped for positions that are entry-level. As reported by the GetEducated.com website, â€Å"An Associate’s degree in Psychology or in Counseling covers: Theories of Counseling Case Management Family and Group Counseling Multicultural Counseling Psychology â€Å" ( GetEducated.com, 2017). What is required for a AOD counselor is a minimal of 2 years of both case management and experience, computer skills like microsoft word, and knowledge of Cognitive Behavioral Therapy. Some straightforward basic qualifications are licensing or certification, a valid driver’s license and dependable transportation. Its vital to have current certification in CPR and First-Aid, along with receiving a TB shot at the beginning of employment. According to Indeed.com, â€Å" Being bilingual,having flexible hours, experience in inpatient/outpatient settings, and knowledge of program planning/ development† is not mandatory but it is sought after by employers (Indeed.com, 2018). In other states, there is education that is considered mandatory like a Bachelor’s or an online Master’s degree for the soul purpose that it provides the AOD counselor with more years under their belt. This allows the AOD counselor to be adequately prepared to assess the patient for methods of treatment. Location as far as states go, does play a huge part in how much is required of an education verses what is preferred in order to have greater job opportunities. It is advised by GetEducated.com to distinguish between what work environment for counselling you want to be in, such as clinical or rehabilitation. For an example, â€Å"Those who want to work in medical and healthcare-specific environments should consider a concentration in clinical counseling. Those who wish to work in social work environments should consider rehabilitation counseling concentrations† (GetEducated.com, 2017). On a typical day, the tasks of a AOD counselor include up-keep on clientele files, assessing and writing reports, and working as team with other professionals to determine an appropriate treatment. Treatment for drug abuse is not the only counseling provided, but also focuses on the overall mental health for the patient and their loved ones. In counseling sessions, critical thinking is demonstrated by the counselors to help with the depression and strain caused by addictions. The mission for AOD counselors is to able to ease the road to recovery for patients by helping them return to a normal setting like find employment or support groups. Often, what leads a patient into relapse is the lack of knowledge of addiction, recognizing behavioral conditions, and what actions to take. The nature of an AOD counselor is all about communicating with those whose lives has been touched by addiction. It is unfortunate that the only time that mental health comes into accountability is when a person is hitting rock bottom. It is irrevocable that we all have the same doubts, emotions and the same destiny in the end, so why is so hard to imagine the person next to us is just as human with their own set of demons. I believe an AOD counselor takes this into consideration, even though not all treatments work the same on every person; it still is a human self destructing. Just some people make it a little more apparent. There are various accommodations or environments for those in need depending on the patient’s situation. From private establishments, state/local facilities, halfway houses, detox centers, to facilities for the juvenile.

A Conversation With Real Life Director Harrison Starr

Event from chapter 1: when Harrison compares anti-war books to anti-glaciers books In the first chapter, which serves as an introduction, Vonnegut directly addresses the reader, pointing out his attitude towards war. The author makes it clear that he sees it as something ugly and horrifying, however, it seems like he is resigned to the fact that war will always exist. In one passage Vonnegut recounts a conversation with real-life director Harrison Starr. When Vonnegut explained that he was working on an antiwar book, Harrison said â€Å"You know what I say to people when I hear they’re writing anti-war books? ... I say, ‘Why don’t you write an anti-glacier book instead?’†(3). Vonnegut informs the reader that what Harrison meant by these words of course, â€Å"was that there would always be wars, that they were as easy to stop as glaciers†(3). In this quote, Vonnegut’s compares war with the glaciers. There has always been war just like t here have always been glaciers. But there will not always be glaciers since they will all eventually melt and when they do, we will suffer. We are unable to live without glaciers, and we are unable to live without war either. No matter how great his anti-war novels are, Vonnegut doesn’t expect them to change society since he already knows that war is unstoppable.

Lack of Communication free essay sample

Sexual harassment is an important example of power abuse that generates negative conflict and it is a highly destructive workplace process. (Shockley-Zalabak, pg. 309) Not knowing how to communicate about such a highly sensitive situation can ruin a person’s life and can ruin the credibility of an organization. It can even affect the job status and reputation of a good employee. Overview of the Organization and Case Study The Village of Bellport is a local government entity with approximately 150 employees that are spread out through out five different departments. The Village of Bellport has had a sexual harassment case between two employees; one is an office employee and one is a highway employee who is also the husband of the office employee’s supervisor. This sensitive situation that has happened is due to the lack of communication between the Mayor, the Board of Trustees and the rest of the staff and has affected the relationships and the morale of the employees. Without going into too many details; the office employee stated that the highway worker sexually harassed her while her boss (his wife) was away in training. The highway worker denied all accusations but was convicted by the board without even hearing his side of the story. The board also didn’t ask anyone that worked that day what they saw or heard or they never asked about the characters of either employee. The outcome was that the highway worker was forced to resign after 13 years of service. Since the office employee didnt get the money she was after from the start, she went after the Village for harassment, saying that all the employees were harassing her because of the situation, which wasn’t true. When the Village attorney and the board found out about her character and what type of person she really was they were mortified and they felt dumb but of course it was too late. Identify and Describe the Situation or Problem Knowledge The major problem with this situation was the lack of communication. This was because of the lack of skills and knowledge that the board had with this kind of situation. With the lack of communication came ruined relationships, plummeting employee morale and the job statuses of certain  employees were changed . By the board not communicating to the employees and to each other, the rumors were started and down went the reputations of everyone involved. There was so much information missing due to the lack of communication between each board member; like, what really happened? What was the two employees saying that happened? This was because of the lack of skills that the board had on how to deal with this. The board only found out one side of the story and never bothered to find out the other employees side. The board assumed that the male employee did wrong just because the office employee said he did and they never listened to a word he said or what his wife was saying or anyone else that had his best interest. The rumors were started and all because of management never told the staff not to speak of this very sensitive subject to the public. This situation had a combination between Maslow’s Hierarchy of Needs and Motivation-Hygiene theory applied. Maslow’s Hierarchy of Needs was applied because the employees lost a lot of their peer’s respect and relationships and they did not feel safe in their jobs as a result of the lack of communication. Motivation-Hygiene theory was applied because this situation was an influence from both internal and external factors. (Shockley-Zalabak, pg. 143) Communication competency (which is composed of knowledge, sensitivity, skills and values) and sensitivity competency (which is the ability to sense organizational meanings and feelings accurately) are lacking in the Village. (Shockley-Zalabak, pg. 5-8) It is because with the Villages communication competency, no one has comfort with conflict so they will not contribute information to the public because they are afraid people will disagree with them. The person that was most responsible for the communication problems was the clerk. Whether it was because he was inexperienced in this kind of matter or he just didn’t care but what he did or better yet, didn’t do was just wrong. He never spoke to any witnesses about what happened and the employees thought they knew a lot about what happened on that day. He did apologize after the fact to the wife of the highway employee because he knew what he did was wrong. The reality is no one knows what went on that day for sure except for the two employees that were in the office that day. Everyone just assumed that the one side was right and never took it as a he said she said case. Hopefully the board and their staff learned how to deal with such a sensitive situation if this ever happens again. The Village is a small community and by the board going home and telling their family and friends about this situation it started the rumors and the stories about what people thought happened. Whether it was true or not, the three parties involved were mortified about everyone knowing and talking about it. The person responsible for the rumors were mostly everyone involved the Mayor, the board, the clerk and other employees which was very disappointing. Yet, no one claimed responsibility. Skills The only skills that were shown in this situation was the listening skills that they showed for one side and the written communication that they showed by giving the highway worker a letter stating the claim toward him and that they would be in touch with him. It took the board two weeks to actually let the employee know what was taking place. The board needs to learn not to be judgmental, they need to be sensitive with matters like this and they need to sharpen their nonverbal communication skills and when something like this happens they need to stop with the rolling of the eyes and the hand gestures toward one another. The organizational skills are also in need of repair. The Village needs to start treating people equally, attempt to resolve the conflict and show empathy. They can learn these skills by working together and practicing good communication. They need to really listen to one another and to their employees without jumping to conclusions. They should try to take some training classes in order for everyone to understand how important it really is. Values Communicating their stories was important to both individuals, they wanted to get out what they were saying happened that day and to be able to have the board believe each of them. One individual wanted to get his story out so he could save his job, reputation and marriage. The other was to make everyone feel bad for her and hate the highway employee and his wife and eventually we found out to get money from the Village. The only value that the two employees shared was that they both wanted to communicate their stories but the board only wanted to hear from one of them and force the other employee out so it would just go away. Because the culture of the organization is all about politics, the board just wanted what was right for the public to see and what will make them look good. They had only themselves in their best interest and no one else. The Village fell for a scam because they were trying to keep themselves out of the headlines and their political values took over. Since the public really liked the highway worker and his wife and they knew about the other employees characteristic, they wound up looking horrible. Develop Alternatives and Test Possible Solutions Propose Solutions and Suggest Implementation Plans What the Village should have done is call the police. If the police did the investigation then the truth hopefully would have been found out. They would have not let their feelings affect the outcome. They also should have let both employees communicate their stories and question other employees that were there that day. The clerk was in the office that day, a code officer was in and out of the office all day, there are cameras in the office and the employee told another employee her story and it changed multiple times. Also, someone should have asked the boss of the employee about her. Whenever the boss would try to speak and explain how this girl was the village just looked at her as the scorned wife. Finding out the characteristics of these employees would have helped the case tremendously. The Mayor and board should have been more discreet about this very sensitive situation. Management should know that letting this information out will only hurt the people involved. The village should have had training about this subject so the employees would know how to handle it when something did happen. Since none of this was followed and the real goal of the office employee was to get money out of this whole thing, she won. After the highway employee was forced to resign she should have continued to work for his wife, who was really swallowing her pride, but she didnt. She knew she had her boss wrapped around her finger and no matter what her boss did this girl would not listen. Then finally the girl started trouble with every employee that entered Village hall by saying they were all harassing her and of course she sued the Village. The best witness in the case was the wife of the highway employee (her boss) who worked side by side with this girl and knew everything about her. If they only listened from the beginning everyones life would not have been turned upside down like it was. Summary Not having the skills in communication can really ruin an organizations credibility or someones life. Dealing with a sexual harassment case is a really tough situation especially when it is a he said she said case. The communication in the Village of Bellport is not where it should be. If the board knew how to handle this situation maybe the highway employee would still have his job and his wife wouldnt have had to go through what she had to. The skills that are needed to extinguish a situation before it spins out of control is having the training that is needed to handle something like this. Knowledge and skills about communication is key and if anyone would have communicated and found the right way to handle this situation, things would have turned out a lot differently.
