Leadership Definitions Of Leadership As A Leader - 1224 Words

At some point in life, someone is required to become a leader; many organisations and specific situations require a leader (Northouse, 2014). No matter the profile of the individual, there are demands placed on the individual which require them to deal with many responsibilities and duties which can be both challenging and rewarding at the same time but this depends on how well the individual handles themselves in these situations. The important question is; â€Å"what is leadership?†. Many people question what this term means as it is a fundamental skill which is required in the workforce (Avery, 2004). Leadership definitions have been approached in various ways with many authors relating to the nature of leadership rather than distinctively†¦show more content†¦There are many definitions for leadership but as defined by Stogdill (1950), it is â€Å"an influencing process aimed at goal achievement† whereby a leader is the individual who is responsible for lead ing a team to set objectives laid out by an organisation (Bolden et al., 2003). It is of course how a leader approaches leading a team that can have a considerable influence of the success of an organisation. As a result of the various definitions of leadership which have evolved over the years, many approaches to leadership have progressed changing the focus and direction of leadership (Rost, 1991). Early theories such as the trait and behavioural approaches focus on identifying the qualities and characteristics presented by great leaders and what those great leaders did and how they acted in particular situations; which characterised them as a â€Å"successful† leader (Northouse, 2014; Zaccaro, 2007; Yukl, 2010). The trait theory identifies that if the leader is endowed with superior qualities that differentiate themselves from their followers, then it should be possible to identify these qualities from a leader (Bass and Stogdill, 1990). The trait theory explains leaderships in terms of personality and character of an individual. Bass and Stogdill (1990) posed two questions; â€Å"What traits distinguish leaders from their followers?

Coral polyps Essay Example For Students

Coral polyps Essay Coral is made by millions of tiny carnivorous creatures that are called polyps. Polyps live in groups called colonies. Each polyp builds a case of limestone around itself, using calcium found floating in the marine water. This is like a house for the polyps, with a floor and walls. After one polyp dies another will soon take its place and begin the construction on his house on top of the past home. Once these formations to limestone increase they tort what we call a coral reef. In shallow water a kind of algae will embed itself and live in the tissues of the polyps. The algae use the sunlight and waste products of the polyp to make the necessities like oxygen and food for the polyps. This kind of algae is called a Contextually. Contextually need sunshine to survive, so due to this they do not live in deep water where sunshine does not filter through Coral reef contains zones that represent different kinds of habitats. Usually there are three zones are present, the fore reef, reef crest, and the back reef. All three zones are interconnected physically and ecologically. The three zones seawater, sediments, nutrients, and marine life among one another _ They are each components Of the oral reef ecosystem that play a role in supporting the reefs complex community Of fish and Other aquatic life. Over four thousand species Of fish inhabit coral reefs over the world. Fish feed either on small animals living near the coral, seaweed, algae, or on the coral itself. This is all a part of the very diverse food chain present in this marine ecosystem. First there are the producers, the phytoplankton on the oceans surface. Then there are the primary consumers, the coral, sea turtle, and fish. Following this there are the secondary consumers, the, anemones, starfish, barracuda, jellyfish, sea snakes and sea slugs. There is also the top predator, sharks. There are also other classifications of coral reef life, the scavengers, fish. Then there are the last but not least the decomposer or detersives, microorganisms, This marine ecosystem can be easily disrupted by the mistakes to humans. There have been over 87 oil spill in the past two years. 4 percent of marine life was killed just from oil, One of the most tragic oil spills to have affected a coral reef was the Great barrier Reef oil spill. The Great Barrier Reef oil spill happened on April 3, 2010. The man-made crisis was caused when a Chinese oil carrier, owned by Sheen Energy Transport Company, hit the OTTOMH of the ocean floor east of Rock Hampton in Queensland, Australia. The vessel spilled roughly four tones of oil into the ocean. The boat avgas more than ten kilometers Off of its shipping lane, meant to prevent such accident causing catastrophes. It hit the bottom of the reef in the afternoon of April third, scraping the reef for a long distance. This scrape is now the longest known grounding scar to date on the Great Barrier Reef. The grounding scar on the Great Barrier Reef is roughly three kilometers long and two-hundred and fifty meters (a Quarter Of a kilometer) wide. Many boats were sent to try and help remove the vessel. With a mooing storm, it was feared that the boat would break apart causing further damage. Eventually they managed to reflect the boat and take it to Harvey Bay, Australia. After many long hours of unloading they had removed about a third of its cargo. Following clean-up, the Sheen Eng was towed to Singapore, The ships captain and its first officer were both charged and lost their jobs as a result of the accident. The maximum fine for shipping companies that cause damage on any reef was increased after this incident. Ay April 13, 2010, oil was washing up on the beaches of North West Island Australia, destroying a large bird and sea turtle jesting area. Many are concerned that there may be considerable long term damage to the Great Barrier Reef, Currently, the damaged areas have become completely void of all marine elite. .uf531846196bcd5b725761d7d43b4e7ee , .uf531846196bcd5b725761d7d43b4e7ee .postImageUrl , .uf531846196bcd5b725761d7d43b4e7ee .centered-text-area { min-height: 80px; position: relative; } .uf531846196bcd5b725761d7d43b4e7ee , .uf531846196bcd5b725761d7d43b4e7ee:hover , .uf531846196bcd5b725761d7d43b4e7ee:visited , .uf531846196bcd5b725761d7d43b4e7ee:active { border:0!important; } .uf531846196bcd5b725761d7d43b4e7ee .clearfix:after { content: ""; display: table; clear: both; } .uf531846196bcd5b725761d7d43b4e7ee { 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; } .uf531846196bcd5b725761d7d43b4e7ee:active , .uf531846196bcd5b725761d7d43b4e7ee:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uf531846196bcd5b725761d7d43b4e7ee .centered-text-area { width: 100%; position: relative ; } .uf531846196bcd5b725761d7d43b4e7ee .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uf531846196bcd5b725761d7d43b4e7ee .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uf531846196bcd5b725761d7d43b4e7ee .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; } .uf531846196bcd5b725761d7d43b4e7ee:hover .ctaButton { background-color: #34495E!important; } .uf531846196bcd5b725761d7d43b4e7ee .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uf531846196bcd5b725761d7d43b4e7ee .uf531846196bcd5b725761d7d43b4e7ee-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uf531846196bcd5b725761d7d43b4e7ee:after { content: ""; display: block; clear: both; } READ: Movie Analysis - Big Fish EssayIt is estimated that it could take approximately ten to twenty years before the Great Barrier Reef returns to its original state as it was before the incident.

Nothing has ever been outfitted on a ship to skim plastic. But lets Say it did, and lets also say it could hold 500 million pounds Of lactic. Youd need 630 of them to do the job.
