American Federation of Labor Essay Sample free essay sample

The industrialisation and mechanisation which took topographic point in United States between 1845 and 1900 gave rise to large concerns and monopolies. This besides resulted in the concentration of industrial capital and power into few custodies. Although labour played an of import function in this procedure of industrialisation and outgrowth of large concern. the makers and enterprisers reduced their rewards. increased their working hours and appointed and dismissed labourers at will. This necessarily forced the labourers to fall in custodies and act jointly. Assorted others factors contributed toward the growing of labour motion. But development this labour motion and brotherhood came in jets. The work stoppage scheme of Knights of Labor turned violent and finally the prostration of the KOL but it paved the manner for a more organized attempt for corporate action. This resulted in the formation of a new organization-the American Federation of Labor( AFL ) which was in favour of old federative program and was opposed to the thought of one large brotherhood.

Cilia and Flagella Function

Cilia and Flagella Function What Are Cilia and Flagella? Both prokaryotic and eukaryotic cells contain structures known as cilia and flagella. These extensions from the cell surface aid in cell movement. They also help to move substances around cells and direct the flow of substances along tracts. Cilia and flagella are formed from specialized groupings of microtubules called basal bodies. If the protrusions are short and numerous they are termed cilia. If they are longer and less numerous (usually only one or two) they are termed flagella. What Are Their Distinguishing Characteristics? Cilia and flagella have a core composed of microtubules that are connected to the plasma membrane and arranged in what is known as a 9 2 pattern. The pattern is so named because it consists of a ring of nine microtubule paired sets (doublets) that encircle two singular microtubules. This microtubule bundle in a 9 2 arrangement is called an axoneme. The base of cilia and flagella is connected to the cell by modified centriole structures called basal bodies. Movement is produced when the nine paired microtubule sets of the axoneme slide against one another causing cilia and flagella to bend. The motor protein dynein is responsible for generating the force required for movement. This type of organization is found in most eukaryotic cilia and flagella. What Is Their Function? The primary function of cilia and flagella is movement. They are the means by which many microscopic unicellular and multicellular organisms move from place to place. Many of these organisms are found in aqueous environments, where they are propelled along by the beating of cilia or the whip-like action of flagella. Protists and bacteria, for example, use these structures to move toward a stimulus (food, light), away from a stimulus (toxin), or to maintain their position in a general location. In higher organisms, cilia is often used to propel substances in a desired direction. Some cilia, however, do not function in movement but in sensing. Primary cilia, found in some organs and vessels, can sense changes in environmental conditions. Cells lining the walls of blood vessels exemplify this function. The primary cilia in blood vessel endothelial cells monitor the force of blood flow through the vessels. Where Can Cilia and Flagella Be Found? Both cilia and flagella are found in numerous types of cells. For instance, the sperm of many animals, algae, and even ferns have flagella. Prokaryotic organisms may also possess a single flagellum or more. A bacterium, for example, may have: one flagellum located at one end of the cell (montrichous), one or more flagella located at both ends of the cell (amphitrichous), several flagella at one end of the cell (lophotrichous), or flagella distributed all around the cell (peritrichous). Cilia can be found in areas such as the respiratory tract and female reproductive tract. In the respiratory tract, cilia helps to sweep mucus containing dust, germs, pollen, and other debris away from the lungs. In the female reproductive tract, cilia helps to sweep sperm in the direction of the uterus. More Cell Structures Cilia and flagella are two of the many types of internal and external cell structures. Other cell structures and organelles include: Cell Membrane: This outer membrane of eukaryotic cells protects the integrity of the interior of the cell.Cytoskeleton: The cytoskeleton is a network of fibers that forms the internal infrastructure of the cell.Nucleus: Cell growth and reproduction are controlled by the nucleus.Ribosomes: Ribosomes are RNA and protein complexes that are responsible for protein production via translation.Mitochondria: These organelles provide energy for the cell.Endoplasmic Reticulum: Formed by the infolding of the plasma membrane, the endoplasmic reticulum synthesizes carbohydrates and lipids.Golgi Complex: This organelle manufactures, stores, and ships certain cellular products.Lysosomes: Lysosomes are sacs of enzymes that digest cellular macromolecules.Peroxisomes: These organelles help to detoxify alcohol, form bile acid, and use oxygen to break down fats.

Leadership Practices at Whole Foods Research Paper

Leadership Practices at Whole Foods - Research Paper Example The company, which entered the stock market in 1992, has undergone numerous tests, including lawsuits and natural disasters but has remained highly competitive. Its distinguishing niche, which also doubles as its competitive edge, is the emphasis on foods, which have not been processed in any way. The company ranks third in terms of preserving the environment. This is due to their concern for a cleaner environment (Edwards 64). This award is among several that the company has received. Despite these accolades, it has faced accusations of using its ‘natural’ slogan just for marketing. Such achievement in a company is because of first-rate leadership by the management and other positive qualities among the management and staff. Leadership styles can affect the working environment, which then affects the efficiency of the business. If the workforce feels that their opinions are of no value or their contribution is insignificant, the jobs may lack satisfaction, and consequen tly, results to poor performance. This and other scenarios are dependent on the style, structure and practice of management (Kouzes and Posner 23). Kouzes & Posner identified five practices of exemplary leadership. These included leading by example, inspiring others, questioning the status, empowering others to do and encouraging the heart. The first practice emphasizes the need for leaders to show the way to the others. It underscores the importance for leaders to portray the values they advocate for, in both word and deeds. They should be at the forefront in the battle they are fighting (Kouzes and Posner 23-42). Inspiring others connote that leaders should light up the passions of their followers. The convictions they have about different issues in the company should be communicated well to the constituents. All means should be used to make sure they hold these convictions as their own. The course of the leader should be the course for all constituents (Kouzes and Posner 43). The y should share in the enthusiasm of the leadership. It is also required of leaders to invent and adopt new strategies for dealing with problems. Great achievements have always followed creative thinkers. Leaders must be innovative in their approaches to problems. Leadership also requires decentralizing of capabilities (Kouzes and Posner 173). The achievement of the goals of the company should be met by involving all the constituents. Everyone should be viewed as part of the future of the company, and everyone’s idea should be acknowledged. Finally, leaders should be able to strengthen the weakening wills. They should instil perseverance and dedication in the face of tough times. They should uplift, for example, by rewarding variant effort (Kouzes and Posner 315). Leadership practice: Empowering people to act Execution The leadership of Whole Foods has employed several of the above leadership practices in different times, and to varied degrees. The most conspicuous of these pr actices is its emphasis on empowering people to act. The employees at whole foods are the main custodians of the company’s processes towards it goals and objectives. The company organises its staff into teams. These teams are responsible for the development of the company (Jones and Hill 288). Each retail outlet has about eight teams on charge of the various departments. The leadership emphasizes this in the process they use to hire new staff. To ensure that the new employees to be hired are of the best quality, they are first
