2. à à à à à à In Changing Minds Gardner talks of an ââ¬ËIntegrated viable identity. ââ¬â¢ How can the work of a site such as ours impact and attempt to create change in a way that supports the development and enhancement of any existing ââ¬Ëintegrated viable identityââ¬â¢ in any of our readers? (Hint ââ¬â this is hard to find yet findable ââ¬â look at references provided in the back of the book to help you find it if needed). As Gardner is interested in creating a science of mind change, he is concerned with the subject both before and after the adoption of the new view. When he discusses the ââ¬Å"integrated viable identity, â⬠it is in reference to the individual after they have converted from a fundamentalist view to the view of the reformer or innovator who is seeking change. The individual who has been changed must have an integrated viable identity for the conversion or reform to be considered a sustainable solution in the society or grou p. If the new idea is not integrated into the individual, it fails to take hold in the mind and thus will not be fully recognized, understood, or used as intended by the person.

Finally, the focus on identity means that the person whoââ¬â¢s mind has changed from a fundamentalist view must make the new idea his or her own, and identify with it, or the conversion attempt will fail a third time to be sustainable. Creating sustainable, integrated solutions to problems caused by wrong ideas leads Gardner to develop a vision of success that is the ââ¬Å"integrated viable identityâ⬠of the individual after mind change. 3. à à à à à à In Changing Minds Gardner speaks of ââ¬ËRepresentational Redescription. ââ¬â¢ à Explain what this is, and whether we have it in our site. If we do, describe where it is and how it works in the site. à Also, explain how you might effectively use it in the future. ââ¬Å"Representational Redescripti onâ⬠as intended by Gardner is a process where the reformer or activist must change the dominant way that an individual or group views a topic, by reversing the traditional associations that relate to a concept, symbol, or process in popular mental conception. An example of this might be Nicholas Talebââ¬â¢s concept of the ââ¬Å"Black Swan. â⬠In traditional Greek philosophy, swans were viewed as a synonym for whiteness, the Greeks never considered or entertained the notion that swans could be black, it was against their fundamental concept of what a swan was, namely a white bird.

The Theory And Its Impact On The Field - 921 Words
Taking history into consideration, there have been many phases that have resulted in a negative turn in the field. I believe that the major downsides to our history have been primarily involved with the strict empiricism point of view and its similar counterparts. Beginning with Aristotle and his concept of Tabula Rasa, it is difficult to prove that this is true. The justification for this theory is minimal as we are far more complex to have a blank mind. Our mind is not blank and we have clear emotions that are present throughout the day. We justify our experiences and learn from them for the future. Our mind is capable of being creative and finding our potential in other aspects that are difficult to explain and attribute their origin from. If we keep believing this or any form of this theory, we would not be capable of seeking new aspects of the field. Initially, the movement towards a having a psychological science did not have much progression. This lack of movement was primarily seen during the Dark Ages. During this era, there was no longer contributions to move science forward. There was a clear hierarchy in which the church resided above all, which hindered the movement towards achieving innovative scientific ideas. Scholasticism was practiced and everyone followed what was allowed by religion. This did not work for the sciences as there were no new perspectives to advance the field.

Organizational Behavior Employee Motivation
Question: Discuss about the case study Organizational Behavior for Employee Motivation. Answer: Why is motivation at workplace essential? In the contemporary corporate world, in order to sustain in the volatile and stern market conditions, the organizations are required to prepare a team of enthusiastic, motivated, optimistic and loyal mavens. The key element for organizational stability and enhanced performances is motivated and passionate employees. Motivation drives employees to accomplish the goals, excel at their jobs and fulfil the responsibilities with positive, exultant and constructive outlook. Motivation is an imperative tool that reinforces employees attitude and behaviour towards their duties and responsibilities and triggers the tendency to achieve the desired targets and objectives with zeal and enthusiasm (Rusu, 2014). Dysfunctional workplace environment, lack of synergy, depressing and gloomy conversations and impassive organizational culture are the demotivating and dispiriting factors which result in unaspiring employees performances, taciturn attitude of staff, absenteeism and high turnover (Greenberg, 2011). As an organizational consultant, it is crucial to analyse and understand the motivation issues presented in the American television series-The Office (season 3, episode 4). Examining the work culture, behaviour, leadership style and motivating or demotivating drivers portrayed in the episode and applying the concepts, models and theories of organizational behaviour and motivation; could unveil the real and actual problems and challenges of the organization along with recommendations and suggestions. Analysis of the scenario of the television show-the office as an organizational consultant. Grief counselling is an edifying episode of season 3. Michael Scott is trying to keep his troop entertained and regaled. After a while he is overpowered with grief, sorrow and depression when he learns about the tragic demise of his former boss, Mr. Ed Truck. Though, the staff consoles him but then quickly gets back to work as nobody wants to confer about deaths, accidents and tragedies. Michael disgusts the employees by imagining bloodbath and decapitation that nobody wants to listen to. Moreover, he summons the staff to a primitive grief counselling session that nobody takes seriously. Michael is so devastated with the concept of death and loss that he even tries to revive a deceased and germ-ridden bird. Employees think of this act as eerie and weird; for them being disheartened and depressed because of a birds death is quite atypical. On the contrary, Michael schedules the birds funeral, despite of knowing that the employees have a lot of work to do. Only Pam tries to comfort Mic hael by preparing a coffin box and a speech. Meanwhile, at a meeting in Stamford, Karen is distraught when Josh asks Jim to supervise her work; she is dismayed to see the vending machine being out of Herrs potato chips, her favourite. Jim, being friendly and kind, helps her find the chips by tracing manufacturers, distributors and Vending Machine Company. Karen is quite happy to see the efforts of her project supervisor. The whole scenario depicts a workaholic team that deals with an overly emotional boss. Overloaded with grief and pain; Michael expects the team to empathize with him. Michael longs for solace and support as he is not able to handle the loss of his former boss. Though, few minutes ago he was amusing the whole team by doing stuffs that bosses dont usually do. This explains that he strives to be surrounded with people and tries to inject personal feelings at workplace (Hellriegel, 2011). However, this disrupts the daily workflow of the team making them feel distracted and side-tracked. At times, the team feels as if he is cares only about his emotions, his moods, his imaginations and his convenience. Nevertheless, he tries to add fun element at the workplace and inflates the value of the employees, when needed. In this episode, he fosters a disconsolate ambience by constantly talking about the tragic incident and his loss. Being a regional manager, he is required to create a positive and energetic atmosphere even in stressed and catastrophic situations. Repeatedly using words like death, blood, accident, tragedy, mishap, etc. make the organizational climate glum and downhearted. As a boss, he needs to ease and comfort the employees to keep their focus intact. He cannot afford to bombard his emotions and sentiments as per his convenience; this can ruin the concentration level of the employees resulting in demotivation. Moreover, his effort to organize a grief counselling session and letting employees burst their emotions out goes wrong because the team does not urge for any counselling session. Nobody is in the frame of mind to reminisce their losses, leaving their crucial tasks behind. Michaels struggle to revive the bird might sound touching but actually it isnt. He is swamped by the emotion of not letting go a living being without trying to save it. His uncanny actions like taking the dead bird into the kitchen area and trying to resuscitate and thereafter, scheduling funeral for the bird make the employees upset about the hampered productivity and loss of precious time. Linking OB and Motivation Theories/Concepts With the Scenario The theories and concepts of organizational behaviour and motivation, study the dynamics of an organizational setting. Concepts like leadership, team-building, decision-making, job satisfaction, organizational culture, training and development programs, strategies, etc. are facets of OB and motivation. This is an interdisciplinary field of psychology and sociology (Ivancevich Matteson, 2005). Vrooms expectancy theory of motivation is based on the three beliefs of the employees: Expectancy: Enhanced and greater efforts would result in high performances. With appropriate resources, skills and support; the employees can put in a lot of hard work and efforts leading to boosted performances (Bloisi, 2003). Instrumentality: High performances would fetch valued outcome. Leaders need to track and evaluate the performances to provide the deserving employees with an outcome. Valence: The emotional orientations of the employees with respect to first order outcomes and second order outcomes. It implies strong preference for a particular reward (Bloisi, 2003). Leaders, who observe the employees determination, performance and output and try to promote their skills and capabilities by rewarding them, create a team of motivated and energized employees (Armstrong, 2006). Similarly, in the situation as presented in the show, the regional manager is required to provide appropriate motivation to the employees by understanding what they actually long for. Michael should understand that the entire team is putting in efforts to achieve its targets and get the desired outcome. Instead of forcing them to grieve and mourn for the loss; he should just motivate the team to concentrate on the responsibilities allocated. The employees require the support, direction and encouragement to perform stupendously and accomplish the tasks, but Michael is emotionally so weak that he gushes out his sentiments and feelings without understanding the mind-set of his team. Since, the team does not get the pertinent motivational drivers, it does not reciprocate what Michael is yearning for. The effective manager theory explains that a manager needs to be consistent and emotionally stable. The foundation of a highly motivated team is an effective manager, who boosts the morale of the employees despite of facing troubles and issues at personal end. An effective manager never lacks in internal fortitude (McShane, 2011). He is the one who strikes a perfect balance between fun and sincerity. He inspires the team to fight back and get out of the bad phase. For him, the workplace should be clean and comfortable physically and psychologically. Michael tries to make the workplace pepped-up by cracking jokes and acting funny, but when he gets to know about the sudden death of his former boss, he drowns into the depressing and dismal syndrome. Though, the staff tries to sympathize with him while maintaining an emotional distance; but he needs a team which engrosses along in dreary and bleak discussions and counselling sessions. This hampers the entire teams energy and verve. Michael does not prove to be an effective manager as he does not try to tone down his feelings nor he tries to understand the employees outlook. Intrinsic and extrinsic motivational theory explains the various drives and reasons for which the employees work hard. The internal desires and wishes for inherent satisfactions like; to act morally, to refine the skills and capabilities, to learn and explore, to sooth the discontent and restlessness, to develop confidence, to help others, etc. are the facets of intrinsic motivation (Lau, 2014). Factors that are external to an individual like money, incentives, perks, status, class, luxuries, etc. are extrinsic motivators (Lau, 2014). Every employee urges for different motivational drivers. It is the prime responsibility of the manager or the leader to understand that urge and desire of the employees. If an employee delivers the best quality output when the leader praises his efforts, provides him with regular feedback and fosters an optimistic and sprightly organizational climate; then he might not get motivated with mere incentives (Champoux, 2011). Similarly, in the fourth episode of the show, the manager is overwhelmed with his emotions and his school of thought and he does not realize what instigator or motivational driver the team needs. The team requires a leader who remains positive even in adverse circumstances and who has high emotional quotient. Recommendations as an Organizational Consultant Emotional sensitivity is healthy, but after a certain limit it becomes detrimental. It is important to manage the strong and extreme emotions especially at a workplace. As a manager, it is important to think about employees motivation. In the scenario as depicted in the episode of the show The Office, the employees find it hard to deal with the managers over sensitivity. As an organizational consultant it is imperative to provide few recommendations which could lead to high motivation level of employees. In the given situation, in order to keep the employees charged and motivated, it is essential to firstly understand that there is a thin line difference between being sensitive and being weak. The manager needs to conduct self-assessment to know if he is being weak and setting a wrong example in front of the entire team. He should also explore his emotions through journaling; this can help him curtail the extreme emotions and responses. Eventually he would be able to spread cheer and optimism making the employees feel passionate and enthused for their tasks (Driskill Brenton, 2005). The manager needs to know what drives and pushes the team to work harder and perform better. If the employees are not showing any keenness or interest in interacting about deaths, calamities and heartaches; then it is a prerequisite for the manager to not force them to do so. This enhances the relationship and understanding between the team and the manager. This leads to high motivational level. Thirdly, if in adverse situations, the manager needs a shoulder to cry on or needs someone to share the feelings with; he can do so, but in a normal and sensible manner that doesnt look peculiar and anomalous. This can make the employees sense the honesty and genuineness in emotions. Hence, they would be able to share their feelings and concerns as well that would result in healthy interactions and strong rapport. References Nygard, R. Celotta, J. (2006).

The American sheep Essay Example For Students
The American sheep Essay There are two common ways of thinking in any specific situation. The first being to fulfill oneââ¬â¢s own personal needs and desires with no specific regard for others around you. The second, basing your decision on how it will be viewed by others. The vast majority of people falls on the side of the second, being greatly worried and influenced by what others are saying and thinking. The ââ¬Å"looking glass selfâ⬠is a term for the image that people have of themselves based on how they believe others perceive them. Both good and bad can come from living in this manner, for the most part however it has seemed to remain constant throughout history. We will write a custom essay on The American sheep specifically for you for only $16.38 $13.9/page Order now People have a natural desire to belong, and fit in with a certain group. Whichever group an individual may choose it is almost inevitable that the individual will be forced at some point, to sacrifice part of themselves in order to obtain the sense of belonging that they desire. People are compelled to seek companionship, often feeling to weak to stand-alone. As a result, they choose to stand together in whatever group they are best suited to. For some this overwhelming fear of being alone can be disastrous. These are people who will stand together with any group good or bad simply to keep themselves from feeling alone. C.S. Lewis hypothesized that the desire to belong and fit in is a natural human characteristic. He believed that people have an instinctive drive to belong, in the same sort of way that a species instinctively is driven to reproduce. Often in society people forming groups commit unspeakable acts, finding shelter in the sheer numbers of those involved. A series of experiments performed some years back demonstrated a term known as ââ¬Å"blind obedience.â⬠A subject was placed in a control booth that contained a microphone and panel with a series of numbered switches. The subject was then instructed that he or she would ask specific questions to a participant in another room. Should the second subject respond with an incorrect answer, the inquisitor was instructed to flip the first switch in the succession. Administering an electric shock to the second subject, which was increased in severity with each incorrect answer given. In reality an electrical shock was actually not being administered, although the person asking the questions believed that it was. The sound of mild discomfort, such as ââ¬Å"ouchâ⬠or a ââ¬Å"damn that smartsâ⬠would accompany the flip of the first switch. As the severity of the shock was believed to be increased so was the sound of the suffering. Working up to agonizing screams of pain and pleading such as ââ¬Å"please I donââ¬â¢t want to do this anymoreâ⬠and ââ¬Å"Iââ¬â¢m begging you please stop.â⬠Whenever the subject administering the shock began to show signs of compassion and not wanting to continue, the researchers quickly reassured them that it was perfectly ok. After explaining to the subject that it was all part of the experiment some people would continue exhibiting little or no resistance. Despite all of their senses telling them that what was happening went against their moral principals. Over eighty percent of the subjects, continued past the point where they believed that the next switch could actually endanger the very life of the other participant. When asked individually why they would cause another human being such pain, for the most part they responded by saying ââ¬Å"because they said it was okay.â⬠This can be directly related to the issue of people doing things because a higher social group or their own peer group gave their approval. In the particular example those involved sacrifice any sense of morals or upbringing that they may have had because ââ¬Å"theyâ⬠said it was okay. .u18d221e78c87e0fd5610ad87f6e7ec09 , .u18d221e78c87e0fd5610ad87f6e7ec09 .postImageUrl , .u18d221e78c87e0fd5610ad87f6e7ec09 .centered-text-area { min-height: 80px; position: relative; } .u18d221e78c87e0fd5610ad87f6e7ec09 , .u18d221e78c87e0fd5610ad87f6e7ec09:hover , .u18d221e78c87e0fd5610ad87f6e7ec09:visited , .u18d221e78c87e0fd5610ad87f6e7ec09:active { border:0!important; } .u18d221e78c87e0fd5610ad87f6e7ec09 .clearfix:after { content: ""; display: table; clear: both; } .u18d221e78c87e0fd5610ad87f6e7ec09 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u18d221e78c87e0fd5610ad87f6e7ec09:active , .u18d221e78c87e0fd5610ad87f6e7ec09:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u18d221e78c87e0fd5610ad87f6e7ec09 .centered-text-area { width: 100%; position: relative ; } .u18d221e78c87e0fd5610ad87f6e7ec09 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u18d221e78c87e0fd5610ad87f6e7ec09 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u18d221e78c87e0fd5610ad87f6e7ec09 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u18d221e78c87e0fd5610ad87f6e7ec09:hover .ctaButton { background-color: #34495E!important; } .u18d221e78c87e0fd5610ad87f6e7ec09 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u18d221e78c87e0fd5610ad87f6e7ec09 .u18d221e78c87e0fd5610ad87f6e7ec09-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u18d221e78c87e0fd5610ad87f6e7ec09:after { content: ""; display: block; clear: both; } READ: Mickey says Christmas EssayPeople throughout history have been influenced by members of society to try drugs, alcohol, and countless other unwise activities. The reason behind this is clear; the human desire to fit in and obtain a feeling of belonging is too strong for most to resist, when the consequences of resisting could mean having to stand-alone. I am reminded of the story of King Midas and his golden touch, although he possessed all the gold that a king could desire he was miserable without being able to have simple human touch. People need people because as a whole we seem to believe that we will become weak and scared if faced with solitude. Will we? Someone once said that what we believe molds our reality. Using this statement I would say that one must ask oneââ¬â¢s self, just what it is that one believes. The natural desire to bond is found every where and in every person with very few exceptions. Sometimes troubles can arise and unspeakable acts are carried out because of certain groups, but the advantages associated seem to outweigh the costs. The groups that people form between themselves often serve as shelters for the lonely, for this reason it seems people will go to extreme measures to belong. Release a lone sheep at the end of a pasture and he will run directly to the flock. Why? Because he feels vulnerable and weak when separated from the flock. Does the sheep care about the rest of the flock? Who can say? What the sheep does know is that being submerged in the flock, the wolf is less likely to focus on him specifically. So goes the life of the American sheep, by conforming to the flock we obtain a feeling of safety and reduce the chances of being the one that the wolves pull down.

Steric Number Definition in Chemistry
Steric Number Definition in Chemistry Steric number is the number of atoms bonded to a central atom of a molecule plus the number of lone pairs attached to the central atom. The steric number of a molecule is used in VSEPRÃ (valence shell electron pair repulsion) theory to determine the molecular geometry of a molecule. How to Find the Steric Number Use the Lewis structure to determine the steric number. The steric number gives the electron-pair arrangement for the geometry that maximizes distance between valence electron pairs. When the distance between valence electrons is maximized, the energy of the molecule is at its lowest state and the molecule is in its most stable configuration. The steric number is calculated using the following formula: Steric Number (number of lone electron pairs on the central atom) (number of atoms bonded to the central atom) Heres a handy table that gives the bond angle that maximizes separation between electrons and gives the associated hybrid orbital. Its a good idea to learn the bond angle and orbitals, since these appear on many standardized exams. S# bond angle hybrid orbital 4 109.5 sp3 hybrid orbital (4 total orbitals) 3 120 sp2 hybrid orbitals (3 total orbitals) 2 180 sp hybrid orbitals (2 total orbitals) 1 no angle s orbital (hydrogen has an S# of 1) Steric Number and Hybrid Orbital Steric Number Calculation Examples Methane (CH4) - Methane consists of carbon bonded to 4 hydrogen atoms and 0 lone pairs. Steric numer is 4.Water (H2O) - Water has two hydrogen atoms bonded to oxygen and also 2 lone pairs, so its steric number is 4.Ammonia (NH3) - Ammonia also has a steric number of 4 because it has 3 hydrogen atoms bonded to nitrogen and 1 lone electron pair.Ethylene (C2H4) - Ethylene has 3 bonded atoms and no lone pairs. Note the carbon double bond. Steric number 3.Acetylene (C2H2) - The carbons are bonded by a triple bond. There are 2 bonded atoms and no lone pairs. Steric number 2.Carbon Dioxide (CO2) - Carbon dioxide is an example of a compound that contains 2 sets of double bonds. There are 2 oxygen atoms bonded to carbon, with no lone pairs, so the steric number is 2. Shape Versus Steric Number Another way to look at molecular geometry is to assign the shape of the molecule according to steric number: SN 2 is linear SN 3 is trigonal planar SN 4 is tetrahedral SN 5 is trigonal bipyramidal SN 6 is octahedral Steric Number Key Takeaways In chemistry, a molecules steric number is the number of atoms bonded to the central atom plus the number of lone electron pairs surrounding the central atom.The steric number is used in VSEPR theory to predict molecular geometry.

A Study On The Blooming Of Convenience Store
A Study On The Blooming Of Convenience Store This research proposal studies on the factors which affect the blooming of convenience store in petrol kiosk. The components of blooming of convenience store are based on the economy of the country, the sales of petrol kiosk, and the spending potential of the customer. Objectives: To investigate how the economy of the country can affect the blooming of convenience store in petrol kiosk To investigate how the sales of petrol kiosk affects the blooming of convenience store in petrol kiosk To find out if the spending potential of the customer affects the blooming of convenience in petrol kiosk Research Question: How the economy of the country can affect the blooming of convenience store in petrol kiosk? How the sales of petrol kiosk affect the blooming of convenience store in petrol kiosk? How the spending potential of customer affect the blooming of convenience store in petrol kiosk? Introduction: A convenience store is a small store that sells items such as bakeries, beverage, biscui t, car care, confectionary, groceries or some selective processed food, lubricants, personal care and household, salty snacks or local tidbits, tobacco, newspaper and magazine. Some part of petrol kiosk may also sell windshield washer fluid, radiator fluid and maps. A convenience store can be a reasonably profitableà businessà because many people will pay extra to buy an item quickly and conveniently or sometimes to make up for the convenience they offer. The price in convenience store are often higher the supermarkets or hypermarkets. The key for a successful convenience store is the location. Thatââ¬â¢s why stores are normally located along busy roads, high population neighbourhoods and petrol kiosk. Travellers normally stopping by for petrol or toilet facilities are often appreciate the convenience of having foods, drinks, reading materials and maps available without having to go to a supermarket. Convenience stores are usually open even when supermarkets are closed and us ually allow for quick shopping and service. For locals, they likely to go to convenience store when their regular supermarket is closed and they need the items such as milk, toilet paper or bread that they already running out at home. However, many locals go to convenience stores regularly to buy magazine and candy. Students often buy cold drinks and snack foods from convenience store. Many convenience stores have microwaves for heating up the prepared sandwiches, soups and hot dogs they sell. Some stores also have coffee and breakfast sandwich special for those people who travel for work in the morning. Drinks and coffee machines and prepared foods are often together in another area and there may be a deli. Newspaper sometimes included in these offers and it may be available at the front counter and or at the magazine rack in the store. Convenience stores often carry at least some ready-to-go items such as muffins and doughnuts. Significant of Study: This study aims at finding out the relationships between the large potential of customer, the economy, and sales of the petrol kiosk, spending potential of the customer and strategic location with the blooming of convenience stores in petrol kiosk.

The role of salt marshes in the coastal system Essay
The role of salt marshes in the coastal system - Essay Example Since salt marshes are shallow areas, the plants that exist in salt marshes are those that can adapt to the tidal changes in the volume of water. The water waves that make it to the salt marshes carry with them tons of organic material which accumulate overtime to form peat. There are many varieties of salt marshes namely: low marsh, high marsh, panes and pools and upland border. Apart from providing thick vegetation, salt marshes are also amongst the most productive ecosystems in the world (New Hampshire Department of Environmental Services, 2004). Role of Salt Marshes in the Coastal System: Salt marshes are sometimes referred to as tidal marshes, the reason being that salt marshes are found in zones between high and low tide. Salt marshes thrive well along the coastal areas because the vegetation is not sturdy enough to withstand strong waves, therefore towards the coastal areas, where the intensity of the waves is reduced to quite an extent, salt marshes thrive (Casagrande, 1997). Salt marshes serve many purposes, namely; they cleanse pollutants from marine water, provide a habitat to many marine species, provide a barrier against soil erosion, provide a source of refuge for the vulnerable marine species, salt marshes are rich in organic matter therefore they form a food chain for the marine life and also provide good nutrient value for the vegetation in the salt marshes (Department of Environmental Protection: Florida Marine Reseach Institute, 2010). Let us throw some light on the varied roles of salt marshes: Remove Pollutants from the Water Since the speed of the waves reduces considerably by the time they reach salt marshes, many suspended particles that are otherwise carried away by the waves throughout the sea, tend to settle. These suspended particles sometimes comprise of toxic nutrients from human activities, thus by allowing them to settle the salt marshes play a key role in cleansing the water of toxic sediments. The thick vegetation helps in slow ing down the waves which in turn causes the particles to settle. Furthermore, during the months of summer and spring the salt marshesââ¬â¢ plants take up the nutrients which if left in the water, would turn into algae, further polluting the water by causing ââ¬Å"Eutrophicationâ⬠and thus depleting the oxygen supply of the water (Cloern, 2007). The toxic contaminants which are settled by the salt marshes form peat which results in the removal of these toxic substances from the marine food web. Moreover, the microbes present in the salt marshes tend to remove nitrogen from the ecosystem (Edwards, 2010). This is beneficial even to the surrounding eelgrass. The reason behind this is that the existence of high levels of nitrogen encourages the growth of phytoplankton. Phytoplankton refers to microscopic organisms that live in water (Lindsey, 2010). This phytoplankton, when in excess blocks the sunlight which is needed for eelgrass to thrive. Therefore, the presence of salt mars hes also benefits eelgrass. Harbour Marine Food Chains The excessive nutrients found in the salt marshes form food chains for marine species. Primarily, the plant matter that partially decays in the salt marshes forms a good source of food for marine species in the deeper waters. This decayed vegetation is taken away by the tidal waves into the ocean where it becomes the food of many marine animals. A two way process runs between aquatic
