Challenges in Groups and Teams - Essay Example Collaborative (C) decision making takes a step in the direction of participation by way of consultation, and involves asking either certain individuals or, more generally, a group for their input. The manager solicits a recommendation from individuals or the group, but still makes the final decision. Empowered decision making completes the continuum. It is full participation, and entails empowering either an individual or a group to make final decisions. The particular people involved in a given communication episode can make the critical difference in whatever understandings result. Personal qualities and background factors influence the interpretations and meanings created by sources and perceivers. There are different key factors to consider with each decision-making style, and different levels of commitment to decisions that can be expected to result from each approach.

Gender Socialization Essay Example for Free

Gender Socialization Essay The term, gender, refers to the socially learned expectations and behaviors associated with being male or female. Gender affects socialization in many ways, and begins primarily at birth. Gender affects how parents treat their children, how the work field treats males and females, and how each gender chooses friends. The gender of a child is extremely important to the parent. The gender will guide the parent on how to raise and treat the child. Parents are more likely to be more stern and rough with a baby boy rather than a baby girl. Parents of a girl are likely to be more gentle, soft, and patient with the new baby. This gender socialization example is due to our masculine and feminine culture. The most important and obvious gender socialization example is in the work field. Gender greatly affects the socialization process between males and females. Males are considered to be strong and powerful, while females are thought to be weak and secondary. From the beginning of time, men were to work hard and provide for the family, while females were to take care of the home and children. Today, men are still more likely to be powerful leaders, CEO’s, etc†¦ however; many women are top executives and are very capable of being so. Finally, gender affects the way people choose friends and social activities. Men are more likely to choose other men as friends, and same with women. Humans enjoy spending time with people that are similar to themselves. Men will also engage in masculine activities such as hunting, fishing, and running, while women engage in feminine activities such as shopping, tanning, and reading. Gender subconsciously helps make our daily decisions. I’ve never thought about gender being such an important aspect in our daily lives. Gender affects socialization in so many different ways; parents raising their children, the work environment, and choosing friends. Gender socialization is extremely important in today’s society.

This price war will lead to decrease price. The five porters force Analysis Industry competitor: In the market industry four large companies are dominant (Kellogg, Nestlà ©, MDD and Jordans). Its an oligopolistic situation (a small number of sellers and a large number of applicants). The competition between the organizations is high and intense because of the price principally. Threat of a Substitution: there are many substitutes because of private label Threat of entry: The cereal industry is oligopolistic, so is very difficult for other firm to enter in this sector. If firm want to penetrate this market he has to have competitive prices, and has to make marketing communication and promotion to attract consumers Bargaining power of buyers: the power of buyer is low in the cereal industry; consumers dont have a deep impact. Bargaining power of suppliers: the power of suppliers is low because the importance of the market shares of private labels. They do exactly the products in cheaper prices. Suppliers can buy product independently.

Essay --

The topic I choose was stress and its effects it has on our body (Myers). These stressors can cause many negative changes to our body, more then we realize. I have a much better understanding after reading not only the textbook but the research journal just what effects it has on our body. It’s easy to listen to people give advice on ways to calm down but I feel people need to be educated on what it does to us and healthy ways to deal with it. There are so many different day to day things that cause us stress and if we allow ourselves we can easily get caught up in them. For me at that point I tune everyone out and that is when those stressors dictate how my day will be. Personally, I realize more now how I have let stress bring me to a point of feeling ill and taking it out on loved ones around me. Now more then ever being a full time student and with recent financial burdens I have seen first hand how stress impacts not only myself but my family as well. We get so enthr alled in stress that we allow it to effect our mind and our body. Then we wake up one day and the stress is still there only we are feeling ill and wondering why. It is so true when people say that stress can cause you to become physically ill. There are so many healthy ways to manage stress however not everyone practices them. We need to use our support systems, identify what the stress is and manage it rather then it taking over us. If we find ways to face the stress, in a healthy way we will be able to resolve it and not have it take over our mind or body. I now find my self coming home after a stressful day and exercising, and going for walks. Instead of me shutting down and becoming stressed I know now that its okay to share this with my loved ones and ... ...cally ill and overwhelmed. By doing this I neglected myself, and by doing so not only did I not deal with stress but there was little resoultion and greater stress within my family. When you get to thast point it is then that the stress is dictating how your days are going to be. This study was very intresting to me and I believe futhur study would help everyone not just health care workers. It brought up many good points, stress is different for each of us and if we had mindfulness approaches then we could face it head on and not allow it to become a neagative outcome. I often wondered having gone to counsling myself in the past how do these therapist deal with listening to patients all day long? What steps do they take to deal with their own stress or just the stress of helping others. I feel the counslor would definitly benefit from this study and its practices.

Democratic Trends Essay

It is inevitable for things to change. The trends in American change daily. There are various factors that influence change. There are many political and economic events and trends that effect the human services field. One of the events that have affected the U.S. is the recession. The recession has caused a trickle down affect. There has also issue with financial budgets. The deficits are attached to various resources that help countless communities throughout the U.S. A few of the demographic trends that have cause change are the aging and healthcare act. There are both good and bad changes that happens in life, and the human service field adapts to that change. We have seem dramatic changes in our government. The political events that effect human services have an outcome that may not be what’s best for the people that are effect. This change in politics have affected millions of Americans that depend on the government system. Minority groups that are recipients of programs that are funded by the government are the ones that are most affected when the government faces distress. The future of human services is always at the edge when crisis arise. The way politicians run their itinerary is by making decisions to what seems convenient for them at the time. Politics is about taking care of one thing at a time and what does not seem important are often left undone. The future of human services faces crisis daily. Budgets are always slash to fix other areas of need. Human services providers are the ones that are in charge of being the voice of the less fortunate pleading to the government to change laws in favor of those in need. If the government does not budget the finances available there is a risk of bankruptcy. Bankruptcy will terminates food stamps, medical, section 8, and many other programs that assist families in need. The future of human services is in limbo it will take for our government to prioritize and put families first. Political Trends that Effect Human Services There are various political event that effect the human services field. One particular event that stands out was the U.S. government shut down due to the recession. The shutdown of government agencies which fund the countless resources and organizations was detrimental to the citizens. There was a boost in varying agencies for those seeking assistance. Some of the organization only assist one specific need. But the consumers requires various aid for needs that may or may not overlap. Some of those needs are general public assistance, unemployment, food stamps, and homelessness. According to â€Å"Human Services in a time of Crisis† studies have shown that food stamp caseloads have a strong correlation to the unemployment rate. It also states a poor economy with high unemployment typically spurs an increase in demand for public assistance (HSTC p. 4). Food stamps are usually the first part of government assistance sought after. Food Stamps are the first part of security for fam ilies in the program for which most applicants are eligible. Government Cuts and Its Consequences The significant cuts made to human services program operating budgets do not promise well for the vulnerable families who are seeking assistance or for their communities. There were various cuts made by government officials to help Americans, but some will cause more damage. The budget cuts to unemployment for instance, means millions of Americans could be left without their sole source of income while they look for work according to U.S.A. Today. About 3.6 million Americans would have become eligible for the program in 2014, in addition to those facing an immediate end to the assistance. The millions that have to survive without unemployment will seek aid through human services agencies throughout the United States. Although homelessness have decreased slightly, there is still an extraordinary need for homes for those experiencing homelessness. According to The State of Homelessness in America (2013), â€Å"The national rate of homelessness was 20 homeless people per 10,000 people in the general population and the rate for veterans was 29 homeless veterans per 10,000 veterans in the general population† (para. 1). Society Facing Economic and Demographic Insecurities As changes are growing, so is the instability of clients that are coping with  depression, anxiety, mental disabilities, and the elderly population. As the country continues in an era of economic insecurity, Americans living close or lower than the poverty line are more at risk. Nonetheless, the assistance they need to acquire jobs, housing, healthcare, or provide for their children is less likely as agencies face impending financial problems of their own. The economic decline began at the end of 2007 subsequently resulting in increased lay-offs, unemployment and underemployment, foreclosures, retirement income and savings loss, and a drop in the value of real estates, placing a larger demand for services on federal, state, and local human service systems. These service delivery systems faced shortages and budget complications of their own. Human service professionals must learn to efficiently and effectively negotiate and bridge this economic gap while meeting their agency’s potentials and needs, respecting their clients and assisting them towards betterment. Economic trend also relating to the production, development, and management of material wealth. Trends will involve jobs, housing, children, and health care. Economic impacts the human services department dealing with the wellbeing of children in many ways, mainly because of all the budget cuts. For example, school is one of the many trends. Teachers are around there students at least 30 hours they’re considered the third parent, good teachers help to mentor their children to become more productive and motivates them to become lifelong learners. Teachers have the training and incite to notice incidence of child sexually, mental and physical abuse. It is the teacher’s responsibility to warn human service of the danger that the child might encou nter. The use of managed care by human service is defined as a set of tools to manage resources and the delivery of human services in the areas of health and mental health care (Woodside, 2011). The impact of managed care organization does not only position a risk to human service values and practice, but also generate an ethical dilemma. Managed care allows the human service profession to develop its professional field increasing from advocating and aftercare for the indigent, severe and chronic mentally ill to providing private non-medical psychotherapy. One challenge of the human service profession is how to sustain improvements within a profession that is characterized by an overlying of roles and functions, and the challenge to meeting the demands of managed care organizations as well as the preservation of values and  ethical practices which make the profession distinctive. The human service profession would need to develop tools to maintaining stability between the needs of clients and the demands of the managed care organizations. Aging in American, which is another demographic trend has taken a toll on society in dealing with housing, confronting death, dying and depression. As the number of elderly people increase, the more help from human services will be required in dealing with their health and living situations. Most elderly men and women will not be financial stable and unable to provide for themselves. The demographic trends targets a diverse population that is in need of strategies and intervention plans to be able to succeed daily. The more communities grow there will be fewer opportunities for the majority of the people to get jobs to support their families. People rely on human services for a boost dealing with unemployment, food, or even help finding better jobs. Human service professionals can also provide assistance to those who are cop ing with trauma from terrorism, disasters, and other traumatic events. Accounts of trauma and violence are characteristically entwined with histories of substance abuse and/or mental health disorders. A few examples are the 9/11 bombing which killed a lot of people and also left many hurt emotional and physical. The effects that terrorism has on people could either be long term (installs fear) or short term (traumatization). Hurricane Katrina, which left everybody in destruction and homelessness. A traumatic event could even include a serious car crash. Societal changes can only begin when an extensive network of service providers integrate their knowledge, resources, and services to the economic and demographic trends within their communities. Conclusion Demographic trends reveal developments and changes in human population (Melva Wilson, 2014). As America is aging we are able to see the changes in human services. Technology has taken over and providers are able to service clients in a more effective and quicker way than a decade ago. As the population grows, the problems in America are also growing. The delivery of services through human services have change and more changes will be implemented in the future. Human services does not only focus on delivering services to the less fortunate, they also have to assure that funds are available to service clients. There will always be changes that will benefit  society and changes that will make their life more complicated. References County Welfare Directors Association of California. (2009).

Radio Essays - Radio Electronics, Broadcast Engineering, Free Essays

Radio Essays - Radio Electronics, Broadcast Engineering, Free Essays Radio HISTORY Towards the end of the 19th century scientists were attempting to send messages over distances without wires. They were not searching for a means of mass-communication, but simply exploring the possibility of using electromagnetic waves in order to communicate between two fixed points. There in no single inventor of radio, it came from several international developments. The pioneers of radio studied the work of a British physicist James Clerk Maxwell, who published his theory of electromagnetic waves in 1873. It was the German physicist Heinrich Rudolf Hertz who first generated such waves electrically. Although, the waves he came up with were unable to travel large distances. It was an Italian electrician and inventor Guglielmo Marconi who succeeded in developing both a suitable receiver and an improved spark oscillator, which was connected to an effective antenna to transmit radio waves over significant distances. In 1896 Marconi transmitted signals for a distance greater than 1.6 km. Within a year of his first demonstration he transmitted signals from shore to a ship at sea 29 km away. In 1899 he established commercial communication between England and France, and in 1901 he succeeded in sending a simple message across the Atlantic. This was still only wireless transmission of signals rather than wireless transmission of sound itself. On Christmas Eve in 1906 an American, Reginald Fessenden, managed to transmit speech and music over several hundred miles out to sea. Over the next few years other demonstrations followed in the United States, Britain, and Europe. The combination of continuous signals being sent out from transmitters and more sensitive receivers laid the technical basis for more wide-scale listening, but there was in the years still little appreciation of the mediums social possibilities. Radio was thought of private means of point-to-point communication, rather than public means of mass communication. The first significant users of radio coastal, marine, army, and intelligence services were, however, content with this approach. Both British and Germans using radio to communicate to naval forces from the outset, and governments commandeering all wireless stations, seemed to entrench this pattern. World War 1 also motivated technical research. In the interwar years, cinema and popular newspapers were already providing ever larger numbers of people with entertainment and information on a national scale. Individuals were being conceived in large numbers and this meant mass markets for all sorts of consumer goods. So when the early wireless amateurs demanded something to listen to, companies such as Marconi in Britain and the General Electric Company and Westinghouse in America were keen to produce radio receivers. The useful function involved in a radio is that you can tune your radio to a radio station by using the control knob on the radio. On a standard radio there are two bands you can switch to AM and FM. FM stands for frequency modulation, and AM stands for, amplitude modulation. The difference between the two bands are the way they are broadcasted. AM is being amplitude modulation the pitch of the radio waves are based on the amplitude of the wave. So for example the higher the amplitude the higher the pitch the radio will receive. As for FM because the waves arent based on the amplitude they are based on the frequency of the waves. So the more frequent the waves are the higher the pitch of the sound. A radio works by using an antenna, which intercepts part of the radio waves. A signal voltage across the coil induces a voltage in the coil, the frequency (AM, FM) is then chosen by the variable capacitor. The capacitor in my circuit is only tuned for AM. Then the frequency comes out of the capacitor and into the transistor, which you use to tune your radio to a station on that frequency. The average electrical power used is:
