Abiotic and Biotic Stresses

Abiotic and Biotic Stresses What causes a plant to be stressed? As with humans, stresses can originate from the surrounding environment or, they can come from living organisms that can cause disease or damage. Water Stress One of the most important abiotic stresses affecting plants is water stress. A plant requires a certain amount of water for its optimal survival; too much water (flooding stress) can cause plant cells to swell and burst; whereas drought stress (too little water) can cause the plant to dry up, a condition called desiccation. Either condition can be deadly to the plant. Temperature Stress Temperature stresses can also wreak havoc on a plant. As with any living organism, a plant has an optimal temperature range at which it grows and performs best. If the temperature is too cold for the plant, it can lead to cold stress, also called chilling stress. Extreme forms of cold stress can lead to freezing stress. Cold temperatures can affect the amount and rate of uptake of water and nutrients, leading to cell desiccation and starvation. Under extremely cold conditions, the cell liquids can freeze outright, causing plant death. Hot weather can affect plants adversely, too. Intense heat can cause plant cell proteins to break down, a process called denaturation. Cell walls and membranes can also melt under extremely high temperatures, and the permeability of the membranes is affected. Other Abiotic Stresses Other abiotic stresses are less obvious but can be equally as lethal. In the end, most abiotic stresses affect the plant cells in the same manner as do water stress and temperature stress. Wind stress can either directly damage the plant through sheer force; or, the wind can affect the transpiration of water through the leaf stomata and cause desiccation. Direct burning of plants through wildfires will cause the cell structure to break down through melting or denaturation. In farming systems, the addition of agrochemicals such as fertilizers and pesticides, either in excess or in deficit, can also cause abiotic stress to the plant. The plant is affected by an imbalance of nutrition or via toxicity. High amounts of salt taken up by a plant can lead to cell desiccation, as elevated levels of salt outside a plant cell will cause water to leave the cell, a process called osmosis. Plant uptake of heavy metals can occur when plants grow in soils fertilized with improperly composted sewage sludge. High heavy metal content in plants can lead to complications with basic physiological and biochemical activities such as photosynthesis. Biotic Stresses Biotic stresses cause damage to plants via living organisms, including fungi, bacteria, insects, and weeds. Viruses, although they are not considered to be living organisms, also cause biotic stress to plants. Fungi cause more diseases in plants than any other biotic stress factor. Over 8,000 fungal species are known to cause plant disease. On the other hand, only about 14 bacterial genera cause economically important diseases in plants, according to an Ohio State University Extension publication. Not many plant pathogenic viruses exist, but they are serious enough to cause nearly as much crop damage worldwide as fungi, according to published estimates. Microorganisms can cause plant wilt, leaf spots, root rot, or seed damage. Insects can cause severe physical damage to plants, including the leaves, stem, bark, and flowers. Insects can also act as a vector of viruses and bacteria from infected plants to healthy plants. The method by which weeds, considered as unwanted and unprofitable plants, inhibit the growth of desirable plants such as crops or flowers is not by direct damage, but by competing with the desirable plants for space and nutrients. Because weeds grow quickly and produce an abundance of viable seed, they are often able to dominate environments more quickly than some desirable plants.

How to Grow a Big Alum Crystal

How to Grow a Big Alum Crystal Alum is found in the spices section of the grocery store. That little jar contains small white crystals that, with a bit of time and effort, you can grow a big alum crystal  that looks a bit like a diamond. This takes days to weeks. What You Need for Alum Crystals 1/2 cups hot tap water2-1/2 tablespoons alumnylon fishing linepencil, ruler, or knife2 clean jarsspooncoffee filter/paper towel Grow the Crystals Pour 1/2 cup of hot tap water into a clean jar.Slowly stir in alum, a little at a time, until it stops dissolving. Dont add the whole amount; just enough to saturate the water.Loosely cover the jar with a coffee filter or paper towel (to keep dust out) and allow the jar to sit undisturbed overnight.The next day, pour the alum solution from the first jar into the clean jar. You will see small alum crystals at the bottom of the jar. These are seed crystals that you will use to grow a big crystal.Tie nylon fishing line around the largest, best-shaped crystal. Tie the other end to a flat object (e.g., popsicle stick, ruler, pencil, butter knife). You will hang the seed crystal by this flat object into the jar far enough so that it will be covered in liquid, but wont touch the bottom or sides of the jar. It may take a few tries to get the length just right.When you have the right string length, hang the seed crystal in the jar with the alum solution. Cover it with the coffee filter and gr ow a crystal! Grow your crystal until you are satisfied with its size. If you see crystals starting to grow on the sides or bottom of your jar, carefully remove your crystal, pour the liquid into the clean jar, and put the crystal in the new jar. Other crystals in the jar will compete with your crystal for alum, so it wont be able to get as big if you let these crystals grow. Crystal Growing Tips You can use sewing thread or other string instead of nylon fishing line, but crystals will grow on the entire length of the submerged string. Crystals dont adhere to nylon, so if you use it, you can get bigger and better crystals.Alum is an ingredient used to make pickles. It makes them crispy.

The reality of Global Warming in the Modern World Research Paper

The reality of Global Warming in the Modern World - Research Paper Example Many techniques have been developed to study how for instance the sea levels have changed over the last few millions of years, even before mankind walked the world. Some of the techniques which have been developed include studying annular rings of old trees, coastal fossils, coral reefs and even fossils in the dry land. Most of these techniques have been used to reveal how climatic change has affected the earth and the life in it, even without the help of the human race. Evidence of coral reefs which have been found in what is now dry land indicates that the coastal lines I most places in the world were further inland. This is evidence that temperature changes can and will lead to changing coast lines and this is a very serious issues for the modern world where big cities have been build on coastlines. There is therefore a need to make sure that these issues are well understood by everyone and that everyone understands what hey need to do. Yet, in the modern world, human activities have increased the rate of climatic change in a very drastic way, making it possible for the climate change to be the fastest in the history of the earth. By studying coral reefs, and coastal reefs, it has been revealed that in the past, coastal levels have been changed a lot leading to the extinction of vitreous specials of both plants and live. In the past, climatic change has been in two ways such as towards receding the coastal line as well as advancing it.

Avatar Essay Example | Topics and Well Written Essays - 750 words

Avatar - Essay Example It is a beautiful story set in the future and teaches people how to take care of resources and minerals while there is still time to do so. The film has been widely acclaimed by most of the world and is also one of the all time best sellers in the box office. Bill Gibron of Film Critic writes, â€Å"At first, Avatar is a bit disconcerting. The lush landscapes, the primeval forests bursting with alien life, the gorgeously lithe Na’vi and their graceful yet strong athletic movements — it’s impossible not to marvel at the creative process involved here.† The movie has taken almost two decades to get out there and has been regarded as wholesome with delicate touches by this particular critic. However, the script has several cheesy dialogues which are predictable and most people think that the silence and music in the movie is what really captivates the audience. The dialogues on the other hand could have been ignored. The performances are extremely solid and within the context. Gibron states that Saldana acted better than even Worthington or Lang in a very stunning manner indeed. On the other hand, another critic from Portland Media Centre writes that the movie was a painful treatise of racism where a white man tries to claim ownership over the last remains of the planet. It talks about acceptance of Jake into the Na’vi society as he wins over even their blood in the end by completely converting into a species of the other form, so that he may win over his lady love, Neytiri. In popular culture this was not accepted by a lot of people and it took over the impressive effects that the movie had to offer. This is because most people understood that one cannot simply give up on their identity in order to grasp another one and at the same time, it is not possible for someone to intrude into another’s society and take over what belongs to them. Thus, this critic has provided the audience with a very sharp take on the film by

The Human Resource Function Essay Example for Free

The Human Resource Function Essay Heathfield (2007) defines Human Resource Management (HRM) as an organizational function; focusing on recruitment, management, and directing the people who work in the organization. HRM can hence be viewed as an organizational function that deals with the human resource â€Å"people who start and operate an organization, (Ramlall, 2003). Owing to the continuous political, economic, social and psychological changes within our societies, there is an increasing need for organizations to constantly evaluate their internal and external environment in response to the challenges and opportunities in the society; so as to remain competitive and to sustain organizational growth. This article examines the strategic role of Human Resource (HR) and its main practices, describes the outcomes of the respective category of (HR) practices and explains the critical reasons for measuring HRs efforts. The fundamental role of the HR to an organization is to â€Å"create value† (Ramlall, 2003) to the organization. It can hence be inferred that the critical HR’s role is to maximize profitability. Every organization, in pursuit of its strategic goals, must determine how particular HR practices correlate with improved business results and be more accountable for each major HR activity. This entails determination of the value of each HR activity in creating a competitive advantage for the organization. Without this, achievement of the organization’s goals and corporate missions may remain a dream that is never attained. There are many factors influencing change in organizational structure today. These factors include technological advancement, globalization, changes in workforce demographics, the elimination of bureaucracies in organizational structures, and the need to strike a balance between work and family issues. Understanding the potential of an organizations resources and optimizing the output of such resources, given the changes, provides an impetus for HR to become the key source of creating the competitive advantage for the organization. It is the role of the HR to build a competitive organization though strategic management of human resources, management of firm infrastructure, management of employee contributions and management of transformation and change. This can be summarized as â€Å"defining the deliverables of work† (Ulrich, 1997). This entails going beyond the strategic business partner role to becoming a player in the business. Ulrich, (1997) identifies six roles of a player in an organization. The player coach, designs, construct, creates followers, plays the rules and changes the organization. This ensures that the functioning of the organization is directed towards its goals. An effective HR personnel acts as a â€Å"facilitator and a collaborator† (Brewster, 2000). As a facilitator, the HR will function as an agent of change- providing rationale, support, and readiness for planned changes designed to support the business strategies. As a collaborator, the HR provides a link between the senior leaders and all employees to implement business strategies forming the strategic link throughout the organization. This is essential to the organization as it helps to maximize its profits. A research by Brewster, (2000) postulates that less than 10 percent of the 968 firms that participated in the study had a formal estimation procedure to measure HRM. This implies that most companies have little or no assessment of their HR department’s efforts and therefore they cannot give any quantitative measures of HRs value to the organization. Hailey, (1999) stated that the best way for HR to gain credibility in order to make meaningful changes is for practitioners to measure the cost and effectiveness of what they do. As such, the HR should be credible enough to lead the rest of the workers towards giving value to the organization. To achieve a competitive advantage, it is necessary to identify the skills that need to be developed internally for current employees and the fundamental areas of effectively managing an organization. The HR function has the most experience and knowledge in addressing these critical issues. It is therefore necessary for an organization to have an effective human resource that can efficiently achieve these vital objectives. The integration of human resources into the organizational strategy provides the basis for enabling the HR function to support and implement the strategic plan to achieve a competitive advantage, (Wofford, 2002). This strategy provides for the maximization of human capital, reduction of wasted and inefficient labor, and other financial investment, eventually to maximize profitability. An efficient HR increases the likelihood of more efficiently achieving the business outcomes and avoiding chaos, massive layoffs, crises resulting from not having skilled employees to carry out particular tasks and not having the right fit among employees, corporate strategies, and business environments, (Hailey, 1999). HR function plays a pivotal role in determining the business strategy through the assessment of the organizations capabilities to compete successfully through a particular strategy, determining the appropriate rewards system, determining appropriate organizational structures, and developing strategies to increase employee performance. All these work in achieving firm’s objectives and assessing the effectiveness of its strategic plan. Given the definition of strategic planning as how an organization will compete, the question arises as to how an organization would be able to assess the effectiveness of its strategic plan. Indicators of a successfully crafted strategic plan include creating advantages that are sustainable over a long period, (Ramlall, 2003). These include attainment of the organizations goals and objectives, the financial profitability of the organization, organizational positioning to create advantages for the short-term and long-term, and creation of a stronger sense of social responsibility. In essence, this process determines the decisions and actions an organization will undertake to create and sustain competitive advantage. It is evident that any organization that endevours to achieve a competitive advantage over its rivals and move towards its strategic goals is left with no choice but to have an effective human resource. The constant evaluation of the effectiveness of the organization results in the need for the HR professional to frequently champion change. Both knowledge about and the ability to execute successful change strategies make the HR professional exceptionally valued. Knowing how to link change to the strategic needs of the organization will minimize employee dissatisfaction and resistance to change. Only an effective HR can champion these important changes.

Examine different sociological views on the change of child

There is really only two views on the change of childhood and they're ‘The march of progress view and ‘The conflict view' both of which are every different to the other. The march of progress view is the view that the position of children In western societies has greatly improved. Aries and shorter , two sociologists of whom hold a march of progress view, argue that children are more valued , better cared for , are more protected and educated , have better healthcare and have more rights all due to sociological changes throughout history.These Include things such as laws estricting child labour, the establishment of policies controlling at what age a child can do things (such as smoke), the introduction of compulsory schooling (1880) , new child protection and welfare legislations and the growth of the idea of children's rights. Lloyd deMause , a social thinker of whom seemed to hold a march of progress view , said In 1974 that ‘ The history of childhood Is a nightm are from which we are Just recently awakening from'. Other sociologists of whom agree with this argue that this Is because not only has society changed as a whole due to new laws, legislations and iews etc. ut also because families seemed to have become more child centred as well as society as a whole. This Is clear as children are no longer to be seen and not heard as they where in Victorian times. They also argue that children are given a better chance of survival due to the development of proper healthcare and higher standards of living thus making childhood better. Many people hold the conflict view that childhood Is quickly disappearing , Iona ople argues against this as through her lifelong research she has found strong evidence hat there Is a very separate culture between adults and children of which didn't exist 50 years ago.The opposing view to that of the marching progress view is the conflict view. This is the view of which Is , held by feminists and Marxists, that childh ood hasn't improvised. Sociologists of whom hold the conflict view argue that one of the main reasons childhood hasn't improved is due to Inequality between both children and adults. They argue that children from different status's , nationalities , gender , ethnicity and class do not have the same resources , chances or backgrounds herefore leaving them unequal.For example according to Mayer Hillman (1993) boys are more likely to be allowed to cross or cycle on roads, use buses and go out in the dark unaccompanied , whereas Jens Bonke (1999) found that girls do more housework than boys , so much so that in some families girls do five times more than the boys in inequality through ethnicity was discovered by Julia Brannens (1994), she found through her study of 15-16 year old girls that Asian parents were more likely than others to be strict towards their daughters.They also argue that there is also inequality between adults and children therefore causing children to experience more control and oppression to that of a child 50 years ago. March of progress writers argue that adults use this power of inequality to the benefit and protection of children. However , critics such as Shulamith Firestone (1979) and John Holt (1974) argue that many things march of progress writers see as care and protection are in fact Just new ways to to force control and injustice on Modern age children.For example Firestone argues that ‘protection' of hildren from paid work is not a form of protection on a child but in fact a way of keeping them dependant on their parents and forcibly creating a segregation between adults and children, of which again is a form of inequality. Another reason they believe childhood hasn't improved is due to the control children experience. Due to the change in society through history and the segregation between adult and children it is seen that adults have more authority over their children, therefore allowing them to control certain aspects of their lives.Such as the pace/places children are and aren't allowed to go, what their child spends time doing and how much time there child spends doing things, there child's bodies and the ways in which they and other people can touch them and the resources their child receives. For example people are allowed to put signs up saying â€Å"no school children† or can band there child from entering a particular estate or place. They can also disallow there child to go out at specific times or set them a time in which they do distinct tasks such as homework or chores.They can also tell a child how to wear here hair or what clothes they can and cannot wear and they can also disallow a child access to the internet etc. These things alone do not come across as an issue but when put together sociologists argue that these things stops the independence of a child and and can even cause a child to be unhappy. Another thing sociologists argue and that isn't rare is that adult control can often lead to abuse in many levels. This can be in 4 different forms physical abuse , emotional abuse, sexual abuse and neglect all seen even in modern day (Daniel Pelka, Baby P etc. ).Another thing sociologists argue that childhood hasn't improved is the way in which technology has taken over our children's lives even in such a way they are constantly glued to a television or games console. This then effects their behaviours and learning abilities which can lead to loss of imagination, shortening of attention span and may cause confusion with fact and knowledge. Sue palmer also found that there where many concerns with teachers as computer games and television was causing children to become more impulsive and distractable therefore compromising ntellectual,emotional and social development.A particular sociologists Neil Postman believed that childhood was disappearing due due to telivisation unsupervised child hood games and rhymes etc. where disappearing therefore children's child hoods where beginning to fade away. In my own opinion I believe in neither the conflict view or the march of progress view as there is lots of little things you have to take into consideration like the way in which life as a whole has changed , for example the fact that theirs at least a case of murder , rape or abduction on the news every single week.Most parents feel as if they have to protect they're children from this and rightfully so. Although some parents may be stricter with they're children than others and some more over protective they all have they're own personal reasons for that. Some parents are strict because they simply want they're children to succeed whereas other because that's the way in which they where brought up. Some parents are more overprotective than other as they only have one child or simply because they're terrified of the disgusting and horrific things that happen here even in the modern era.On one hand I believe that childhood has improved as children are no longer working from the age of 3 and are now given a chance to mature before being pushed into the world of work. On the other hand I think particular aspects of childhood life hasn't improved as children as still being neglected and abused and are very much so reliant on there parents sometimes when they don't actually need to be , also a lot of independence and freedom is being taken away from children from no fault of they're own. So overall I believe in some aspects childhood has improved in others not so much.

Production Lay-outs

Product layout or assembly line is designed to handle products that are manufactured using specialized machines in an assembly line (Product lay-out).   Each line is designed to address specific requirements of a product line in a sequential manner.   There is a smooth flow of production (i.e. conveyor-supported) from one specialized machine to another which is desirable in mass production where demand is predictable while volumes are high.   This type of layout, therefore, is fitted in producing consumer products for a general market rather than producing for several segments of the market. The advantages of the product layout are its order and efficient processes that can lead to faster customer response and less demand on lead times.   It also promotes cheap labor because skill requirements are low that causes relaxation of high salaries.   Although this layout is efficient and easy to use, it is highly inflexible because a change in one assembly line can lead bottleneck in its production.   Further, in product development, acquiring a whole new set of machines and working area is necessary to address specific requirements of the product.   When demand is low, the assets can be underutilized. As it produces ships and airplanes, fixed position layout is a technique applied to vulnerable, hard-to-move and specialized products (Layout and Flow).   Factors of production (e.g. labor, machine, equipments and tools) are required to meet in a single production location to handle manufacturing tasks there. It is customary to leave machines in the site when not used to prevent breakage or damaged in addition to the costly transportation required for pull-out and getting back to the site. Further, to minimize the high capital in acquiring new machines, most companies are using contractual leases because their use of the machines is under limited time frame.   Its advantages are reduced movement of machines that aids in minimizing risk of damage or lost and continuity of processes because the need for re-planning is reduced as people meet in one place.   However, some of its disadvantages include are higher salaries as workers must have specific skills to finish the project, movement of people/ machines to site can be very costly and idle machines can have low utilization because they remain idle rather use for productive means when the production is at cease. Unlike fixed position, functional or process layout distinguish the work group into different departments that give rise to different and distinct workstations (Facility layout).   As production is intermittent and batched, functional layout is compatible in serving different market segments that have highly differentiated needs.   Compared to product layout, volumes are considerably low while the demand can fluctuate considerably from one period to another.   There is specialization in functional layout such as separation of men, women and children's clothes in a department store. Machines in this layout are for general use while workers are knowledgeable on how to operate machines within their station.   The advantage of this layout is opposite the disadvantage of product layout (i.e. flexibility) while the vice versa is also true (i.e. functional layout is inefficient).   Disadvantages such as backtracking, bottlenecks and delays are common.   Further, the storage rooms for raw materials are huge while inventories of the finished products are low because they are immediately delivered to customers.   The critical issue to consider in this layout is to find the relationship of each station to machine centers to establish a more space-efficient design between them. To address the issue to space-efficiency between stations and machine centers, cellular layout is idealized to combine the advantages of product and functional layouts (i.e. efficiency and flexibility).   Cells represent a workstation that produces similar customer requirements.   A machine that cannot be allocated in space is strategically located between cells that require machine processing to create a point of use.   The usual design is that the assembly line is observed in producing components and parts while process layout take-over the relationship of each component-producing cell. With the use of information systems, locating cells and identifying idle machines can be easily carried out.   Resulting to substantial paperwork to maintain the cellular layout, workers can also operate machines within their departments like functional layout.   Its advantages are reduction in material handing and transit time, minimal set-up time, minimized work-in-progress, efficient use of human capital, control and automation.   On the other hand, it can have backlash such as absence of sufficient number of part stations to create cells, imbalanced cells, more training and strict allocation of workers and increased capital expenditure. Justification of the most appropriate layout Although challenging to establish, the current environment and production needs of Manychip should use cellular layout.   First, its plant and sales channels are located in developed economies where quality and expensive human resources are dwelling.   Second, it operates in a highly volatile demand that can be easily affected by environmental changes that flexibility is required to prevent cost associated with over-forecasting.   Third, it is carrying only six main memory chip products which likely have significant similarities in design and internal parts.   This will enable creation of cells because the number of stations is sufficient. Fourth, its operations in asset-intensive while its depreciation can significantly affect its profitability.   When cellular layout is adopted, assembly lines can efficiently produce component parts for the six product lines which will prevent idle machines.   On the other hand, functional layout are flexible that can be applied when orders are placed and products are ready for final assembly.   Fifth, the production of Manychip requires high lead times which can be minimized when applied with cellular manufacturing as components are ready to undergo assembly once order is in place. On having greater agility, Manychip will not loose quality systems because specific stations are under stand-by mode that can be called if random quality test is necessary.   With the consideration of the three conditions, approval of cellular layout is very necessary.   Different components can create cells, the administrative group can act like a quality group in which case a station can be brought up for them near their respective process interests and shipment in different geographical location can be addressed by timely delivery of products.   However, Manychip must consider that substantial funding is required to establish a hybrid strategy such as cellular manufacturing.   It must also monitor its product development programs to prevent dissolution of important cells.

Emotions and Behavior at Work

Emotions and Behavior at Work The role of emotions has been of great interest to business administrators who try to make employees more motivated and committed to organizational goals.Advertising We will write a custom essay sample on Emotions and Behavior at Work specifically for you for only $16.05 $11/page Learn More This paper will be aimed at discussing the differences between felt and displayed emotions. Moreover, it is necessary to examine their impact on workers’ well-being. Overall, it is possible to say the ability to express felt emotions is important for every worker. A person, who has to suppress or conceal them, is more likely to feel dissatisfied with the quality of ones life or work. Moreover, the task of managers is to maker sure that employees can see the positive aspects of their experiences in the workplace. This is how they can improve emotional wellbeing of their subordinates. Overall, this term emotion can be defined as a short-term mental state that can be caused by any external or internal event (Fink 2009, p. 3). This mental state is based on cognitive assessment of any particular situation. Moreover, emotions are normally accompanied by certain verbal and behavioral responses, for instance, excitement, sadness, interest, or anger. By understanding the emotions of workers, managers can better understand their needs, goals, or problems. First, it should be noted that employees have to be skilled in managing their emotions in the workplace. They are not supposed to display those feelings or emotions that can be associated with negative experiences. (Pugh, Groth Hennig-Thurau 2011, p. 377).Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Such situation is very widespread in service organizations employees have attach much importance to their behavior or physical appearance (Pugh, Groth Hennig-Thurau 2011, p. 377). The felt emotions can be shaped by everyday experiences of the employees, their relations with others, their job satisfaction, the degree of empowerment, compensation, and so forth (Bono et al 2007 p. 1357). Cognitive appraisal of the situation can give rise to a specific response, for instance, pride, enthusiasm, pleasure, boredom, and so forth. Positive emotions enhance the sense of wellbeing and increase an employee’s satisfaction with his/her work (Staw, Sutton, Pelled 1994, p. 52). Apart, from that they lead to such outcomes as greater motivation, willingness to take part in the teamwork, and better productivity (Staw, Sutton, Pelled 1994, p. 52). In contrast, negative emotions often result in absenteeism, low productivity, rudeness, or lack of commitment to organizational goals. They are associated with depression, lack of motivation, or even aggression. The thing is that emotions can be accompanied by self-reflection when a person tries to determine the cause of a particular sensatio n. In particular, he/she can pay attention to those things as family relations, compensation, the nature of work, the position in the workplace hierarchy, and so forth. Overall, it is possible to say that the felt emotions reflect the well-being of an individual. In contrast, displayed emotions can be understood only as a set of bodily and behavioral responses that a person has to display during work. From a psychological point of view one cannot even say that these responses can always be called emotions.Advertising We will write a custom essay sample on Emotions and Behavior at Work specifically for you for only $16.05 $11/page Learn More The thing is that emotions have to be based on the assessment of events or situation. Very often displayed emotions run contrary to the actual experiences of an employee (Lapointe et al 2012, p. 3). They do not always correspond to a person’s views, sensations, attitudes, or values. Employees often have to fake th e emotions that they display. This issue should be taken into account by managers who try to motivate their employees. For instance, they should remember that in many cases such emotions as excitement or enthusiasm can be faked. The expression of felt emotions helps a person because in this way he/she can better understand ones experiences. More importantly, other people can detect that this individual can have some psychological problems and assist him/her if it is necessary. Therefore, displayed emotions can be viewed as a positive phenomenon when they really reflect the well-being of a person. Nevertheless, behavioral norms established in many organizations prohibit the display of felt emotions, especially if they are negative ones. Psychologists argue that employees have to be skilled in emotional labor or surface acting (Scott Barnes 2011, p. 116). In many cases, people have to display positive emotions such as optimism, interest, admiration, enthusiasm, and so forth. Unfortun ately, they are often faked. The researchers often try to examine the effects of this surface acting on an individual. The study carried out by Pugh, Groth and Hennig-Thurau (2007) suggests that a person who is engaged in such surface acting, often experiences the so-called emotional dissonance (p. 377).Advertising Looking for essay on business economics?

It is assumed that such behavior can lead to mood disorders, job dissatisfaction, absenteeism, and lack of motivation (Pugh, Groth Hennig-Thurau 2007, p. 386). Overall, employees, who have to be engaged in surface acting, feel this lack of authenticity, and their wellbeing usually deteriorates. Admittedly, such effects do not manifest themselves in every case. Some people are quite capable to work under such circumstances, and emotional dissonance does not usually impact their well-being. Nevertheless, one should take into account that the effects of emotional dissonance can be rather dangerous. The thing is that a person, who has to display unfelt emotions, can actually behave aggressively at home. It should be noted that the most concealed emotion is anger (Mann 2009, p. 32). Sooner or later a person can give vent to this emotion, and very often the relatives of this individual have to suffer because they may not even know what caused this anger. These are possible effects of displaying or suppressing emotions. In most cases, they adversely affect the wellbeing of an individual. Researchers believe that the task of business administrators is to address emotional dissonance of employees. Their goal is to make sure that work experiences of employees are positive ones (Schmisseur 2003, p. 2). There are several things that managers should do. First, they should recognize and reward the successful performance of their workers. Secondly, they have to empower workers and allow them to take initiatives. These people have to feel that their experience and skills are valued by the management. This is how one can improve the wellbeing of workers and avoid emotional dissonance. They should remember that positive emotions displayed by an employee can correspond to his inner experiences. Yet, it is positive when a worker feels that he/she is an important part of a company. These people should associate their work with some positive experiences such as professional fulfillment, success, or empowerment. Therefore, their felt and displayed emotions will be positive. Secondly, managers should take into account that some external environment can affect the emotions of a worker. For instance, family problems can be a very powerful stressor and it may be difficult for an employee to display happiness or willingness to assist a customer at any cost. It will be difficult for him/her to control displayed emotions. Thus, managers should provide their employees with an opportunity for displaying the emotions that they really experience. Some companies prefer to hire a counselor who is able to discuss various issues with employees, in particular, they can speak about workplace conflicts, family quarrels, job dissatisfaction, and so forth. The very discussion of suc h problems can contribute to emotional wellbeing of an employee. Psychologists believe that social support received from peers or supervisors is important for emotional well-being of an employee (Schmisseur 2003, p. 7). The thing is that it can mitigate the negative effects of emotional dissonance. On the whole, these examples show that successful performance in the modern workplace requires the ability to control ones emotions. These mental states affect people’s attitude toward their work, their relations with others, and their overall wellbeing. Managers should know that felt and displayed emotions do not always coincide and their task is to reconcile them. In many cases, workers suffer from the so-called emotional dissonance which is the difference between felt and displayed emotions. In many cases, it leads to work dissatisfaction, aggression, or lack of motivation. Positive work experiences and social support of managers can prevent such problems because workers will no t have to fake or suppress emotions.

Understanding the Role of a Wet Nurse

Understanding the Role of a Wet Nurse A wet nurse is a lactating woman who breastfeeds a child who is not her own. Once a highly organized and well-paid profession, wet nurses had all but disappeared by 1900. Before the invention of infant formula and feeding bottles made wet nursing virtually obsolete in Western society, aristocratic women commonly hired wet nurses, as breastfeeding was seen as unfashionable. The wives of merchants, doctors, and lawyers also preferred to employ a wet nurse rather than breastfeed because it was cheaper than hiring help to run their husbands business or manage a household. A Career for Poor Women Wet nursing was a common career choice for poor women among the lower classes. In many cases, wet nurses were required to register and undergo medical exams. During the Industrial Revolution, lower-income families used wet nurses as more and more women began working and were unable to breastfeed. The rural poor- peasant women- began to assume the role of wet nurses. The Advent of Formula While animal milk was the most common source for replacing human milk, it was nutritionally inferior to breast milk. Advances in science enabled researchers to analyze human milk and attempts were made to create and improve on nonhuman milk so that it could more closely approximate human milk. In 1865 chemist Justus von Liebig patented an infant food consisting of cows milk, wheat and malt flour, and potassium bicarbonate. The introduction of infant formula, the greater availability of animal milk, and the development of the feeding bottle reduced the need for wet nurses throughout the latter half of the 19th century and well into the 20th century. What's Different Now? After the rise of formula and the decline of wet nursing, the once common service has become almost taboo in much of the West. But as breastfeeding is an increasingly acceptable practice once more, mothers of infants are feeling the pressure once again to nurse. However, uneven maternity leave benefits around the nation and the real difficulties of breastfeeding mean that some women would likely benefit from returning to the age-old tradition of wet nursing. As The New Republic reported in 2014, sharing nursing responsibilities- whether by formally hiring a wet nurse or by figuring out an informal arrangement among friends- was looking to be a reasonable solution that could relieve the burden on working mothers without compromising their babies’ feeding. The practice remains controversial. Even the breastfeeding advocacy group, La Leche League, was discouraging the practice in 2007. According to spokeswoman, Anna Burbidge: There are very strong reservations against it, both medically and psychologically. There are potential hazards. The biggest risk is that of infection being passed from the mother to the child. Breast-milk is a living substance expressly designed by your body for your baby, not someone elses. Despite these risks, its not surprising that in this age of ridesharing and spare-room sharing, milk sharing is a phenomenon that some families are now trying. A Facebook group and milk-sharing sites have appeared, and according to a Netmums.com piece from 2016, the practice is on the rise. Their 2016 informal poll found that one in 25 women had shared their milk, and 5 percent of families had used milk from the more regulated source of a milk bank. As the taboo slowly lifts, this age-old practice may just make a real comeback. Source Stevens, Emily E., RN, FNP, WHNP, Ph.D., Thelma E.

Elements of the Legal System Essay Example | Topics and Well Written Essays - 1250 words

Elements of the Legal System - Essay Example The adversarial type is always seen on films and read in novels. The adversarial model works in two types of criminal cases: First are the celebrated cases, where famous people are involved, or cases that are horrifying and beyond the normal type of crime. Second are the serious felonies, which include serious misdemeanors that are done by strangers. The consensual model is a model classified as more effective because there is good cooperation from both the defense and prosecutor. In this model, the two attorneys from both sides share the same understanding of the crimes and punishments. These attorneys think that arguing over the case will only slow down the court proceedings of the case when their main purpose is to make the process faster and finish the throng of cases as quickly and effectively as possible. Crime Control vs. Due Process Models. Crime control model is the assurance of public protection. This type of model believes that all criminal suspects are guilty; thus, their cases should be dealt quickly in the courts or in any other legal branches. The legal process of this model with the criminal suspects is characterized like that of a conveyer belt where all cases and the suspects pass by in the conveyer belt quick and fast. â€Å"Crime control and consensual models complement each other since crime control gives importance to quickly and efficiently convict criminal suspects to ensure the public their safety† (Barkan, 2009). The consensual model gives importance of the same goal but only because to ensure of the continuous and uninterrupted court proceedings. In contrast, due process model is a model that protects and ensures the suspected criminal from the likely abuse of the government of its power. This model take into consideration that the suspected criminal or defendant is innocent of the charges thrown at him. In a democratic country, both the innocent and the guilty deserve to have proper court proceedings and ensure of their indivi dual freedom. The adversarial model and the due process model â€Å"complement each other† since the former model stresses on challenging the evidences of the two parties while the latter highlights on protecting the rights of the suspected offender (Barkan, 2009). Lawyers The significance of the function of a defense attorney is to talk and act in behalf of the defendant. A defense attorney understands the fair process of the criminal justice system. A defendant is in need of every legal advice and counsel throughout the court proceedings, and a defense attorney is the one that gives such. A defense attorney also â€Å"represents the defendant after the he or she is taken into custody†¦to give advice and to make sure constitutional rights are not violated during pretrial procedures† (â€Å"The Adversary Justice System,† n.d.). The prosecuting attorney does not give advices the same way a defense attorney does. A prosecutor’s responsibility is making sure that parties involved in the trial are conscious and be aware of legal measures. Prosecuting vs. Defense Attorney. The prosecuting and the defense attorneys both lay their sides to the judge and to the jury, and during the trial proceedings of the case both are involved. The prosecuting team goes first in presenting evidence that proves the conviction of the defendant followed by the defendant who is going to present his or her
