Marketing - Essay Example These strategies include the reduction of the number of materials for packing used, the use of packages that are environmentally friendly, use of reusable containers and giving support to the services that involve the collection and recycling of packages (Murphy & Donald, pp 203 & 204). The improvement of the performance system can be affected by the reduction of packing. For instance, the carriers’ tariffs and carriers’ classifications affect the nature of packaging and the packing techniques that should be used. Moreover, the specifications of carrier for defensive packaging cut the probability of destruction to products during carriage; this decreases the loss amount and the damage allegations that do not favor the carrier (Murphy & Donald, pp 206 & 207). Among the ten principles of material handling, the most surprising ones are the ergonomic principle and the work principle. The ergonomic principle aims at adapting work to suit the workers ability. This principle is surprising because of the fact that it tries to encompass the workers mental tasks something that appears almost impossible. The other principle is surprising because the minimization of material handling work without sacrificing productivity is not an easy task and is tricky (Murphy & Donald, pp213). The fragmented logistics and unified logistic of the organizational structure are comparable because, in both, the multiple logistics activities can be put in the same department despite their differences. These two logistic structures, however, differ because, in fragmented logistics structure, the activities management is in multiple departments while in the unified logistic structure, all the activities are managed in one department. Moreover, the classification of unified logistics structure is based on the quantity and the action given to the department. The classification of fragmented logistic structure is, however, based on quantity and the activity given to

Reinforcement of Dental Composites by Electrospun Nanofibers Research Proposal

Reinforcement of Dental Composites by Electrospun Nanofibers - Research Proposal Example Our work draws support from the background researches concerned with the application of nanoscaled reinforcing materials and organic-inorganic hybrid nanocomposites synthesized by conventional soft chemistry procedures on various innovative industrial products. The principal look out of the following investigation is also based on the previous studies conducted to understand the intricate mechanisms behind the phenomenon of dissipation of energy that is hypothesized to be one of the definitive factors for hiking the index of fracture toughness in solid composites. (Composites Science and Technology, 2008) Past researches show that this energy dissipating phenomenon implicating increase in the fracture toughness is far more definitive and effect enticing for nanocomposites compared to ordinary composites having micron scaled fibers. In the following investigation we attempt to understand and interpret the reasons associated with mimicking such kind of mechanical strength and structure d toughness after reinforcing the resinous polyacrylate matrices of the dental composites with hyperbranched polymeric nanofibers. ... (Saudi Dental Journal, 2006) Though such research is always critical and is undoubtedly clouded by several other unaccountable factors, like, the inherent clinical design of the prosthesis, deformations of the dental base, climatic wear and tear of the metal supports, conditions leading to accidental damages along with the gender, age and total span of usage of the wearer; the plausible causes arising from the discrepancies in the mechanical index of the denture material itself, was the only object of our interest for pursuing further investigations along relevant lines. Therefore, it is undoubtedly clear that the primary objective of this research is to record and understand the effects of the covalently bonded nanoscaled organic reinforcements on the performance and durability index of the recently used dental composites. By designing composites of polyacrylate resin matrices modified with commercial dendritic polymers, like polyesteramide and polyester, we need to create a variati on from the previous investigations by incorporating electrospun polyamide nanofibers into the system and test their effect on the overall mechanical strength of these composites. EXECUTIVE SUMMARY: The nanofibers will be synthesized by electrospinning three different polymers that are Poly Vinyl Alcohol (PVOH), Poly-L-Lactide Acid (PLLA) and Nylon 6 (Polycaprolactam or Polyamide or PA6) and they are to be used with the Hybrane modified acrylate resin matrix of the composites at different weight percents and particle diameters. The compressive strength, diametric tensile strength, linear shrinkage index and flexural strength will be measured at different concentrations and diameters. The morphology of the

Helicobacter pylori (Microbiology CS3) Case Study

Helicobacter pylori (Microbiology CS3) - Case Study Example It is also believed to be the etiologic agent for peptic ulcers, gastritis and other gastric disorders (Mobley, Mendz and Hazell, 2001). H. pylori produces several key enzymes that enable it to survive in the host. The enzyme, urease, catalyses the breakdown of urea, which is abundantly available in the stomach, into ammonia and bicarbonate (Helicobacter Foundation, 2006). The resulting ammonia surrounds the bacteria, proving a basic (low pH) environment that protects the bacteria from stomach acid. Another enzyme, superoxide dismutase, protects the bacteria from being killed by macrophages and polymorhonuclear leukocytes by breaking down the dismutase produced by them (Mobley, Mendz and Hazell, 2001). Catalase protects the bacteria from hydrogen peroxide produced by phagocytes (Mobley, Mendz and Hazell). According to the Centers for Disease Control and Prevention, H. pylori infection afflicts almost two-thirds of the entire population of the world (CDC, 2005). Developing countries have a higher incidence of H. pylori infection than developed countries (Mobley, Mendz and Hazell, 2001). The infection is more prevalent among lower socio-economic groups and in older adults (CDC, 2005). In the US, Hispanics and African Americans are found to be the most affected (CDC, 2005). The rate of acquisition of the infection differs greatly, both within and across countries (Mobley, Mendz and Hazell, 2001). The bacteria first adhere to the mucin in the epithelial cells of the gastric mucosa (Mobley, Mendz and Hazell, 2001). By altering the rheological properties of the mucus gel, the bacteria coats the lining of the stomach wall (Celli et al. 2009). It then generates a cloud of ammonia around itself to achieve low pH for protection from stomach acid. The ammonia is produced by the hydrolysis of urea. The bacteria also produces phospholipase A that degrades cell membranes by breaking down phospholipids (Mobley,

How would scholarship funds help you - Essay Example But more than getting good grades, I will become a better nurse with a help with a scholarship fund because I have focused on my studies when I was still in school. Nursing is a very demanding career because the health and well-being of patients depends on us (in addition to the doctor). It requires a thorough preparation during school and this means studying full time to be able to absorb and grasp of the entire rudiments and lessons of nursing so that when patients will be entrusted to us, we would be able to take care of them well. Being able to take care of the patients’ well will also be good to my career as a nurse and this would entail progression in my career. But before having a career, I must do well with my studies first. A scholarship fund will be a huge help to make these aspirations a reality because it will ensure that I can enrol in my nursing

Fieldler's Contingency Theory Research Paper Example | Topics and Well Written Essays - 750 words

Fieldler's Contingency Theory - Research Paper Example This scale measures the leadership style of an individual by taking into consideration the opinion of the persons that have been able to work the least well with the subject. The theory might seem a bit odd since one would think that the opinion of the person that you had trouble with would not be such an important factor. The theory can be used to differentiate between relationship motivated styles and task motivated leaders. There are three situational control variables that must be considered. The three situational control variables are leader-member relations, task structure, and position power. The Fieldler contingency theory can be used in the workplace to improve the performance of the workers by using the best leadership style based on the circumstances. Take for example a project manager leading a group of workers. The workers the project manager was given were a group of recently recruited employees. They lack a lot of experience at the work tasks and have little knowledge of the corporate culture of the firm. Based on this scenario it would be more effective for the project manager to use a task orientated leadership style. The project manager should pay close attention to each member of the crew to make sure that the workers understand what is expected of them. The project manager should establish good communications and relations with the workers to build a bond of trust. In the future once I reach a position where I have to exert leadership to manage a group of people I plan on using Fielder’s contingency theory to my advantage. If I was faced with leading a group of workers that had lots of experience, good interpersonal relations among themselves and with the boss, understanding of the culture of the firm and clear knowledge of what is expected of them I would use a relationship-motivated leadership style. A company that has utilized Fielder contingency theory to improve the performance of its workers is Sears Roebuck. Contingency theory has tremendous utility because it can be applied in a wide variety of industries. The theory allows the leader to adapt to the circumstances. The academic community has used Fieldler’s contingency theory in research studies to test different aspects of leadership. A study performed on 360 senior managers across 20 different British firms concluded that leadership and decision making must be analyzed form a contingency rather than a universalistic perspective (Heller, 1973). Fieldler’s work has evolved and recently the theory has evolved through the development of cognitive resource theory. The new cognitive approach states that that leader should use directive or nondirective behavior based on situational contingencies such as experience, support of the leader, and stress. For example when leaders have to manage a group of employees working on tight deadlines such as an accounting staff during the closing period the leader should not exert excessive pressure on the sta ff since the worker already realizes the deadlines they have to meet. Being a facilitator during these circumstances is a more effective leadership style. Contingency theories such as Fieldler’s direct their research towards discovering the variables that make certain leadership characteristics and behaviors effective in specific situations (Gunbayi, 2005). Contingency theory can be very effective in fast adaptive environments such as a casino operation. The casino

Some exam questions I need explained - Essay Example PEST (Political, Economical, Socio-cultural, Technological factors) analysis is an important strategic planning tool. It proves to be a useful stepping stone for the analysis of external factors for an organization. It is also useful to analyze the feasibility of a certain project with reference to different external factors that might affect its execution. This model covers a broader aspect of the prevailing environmental factors than SWOT analysis. Porter’s 5 Forces: This model was developed by Michael E. Porter in 1980. He formulated the model on the basis of 5 competitive forces that tend to determine the nature of every industry. Organization can evaluate the level of competition, profitability and acceptance rate of an industry with the help of these forces; threat of new competitors, bargaining power of the suppliers, rate of rivalry in the industry, bargaining power of customers, threat of substitutes. Value Chain Analysis: It is considered to be a systematic approach; involves a sequence of functions and actions that build value for the organization. Value chain analysis plays a major role in the development of competitive advantage in the market. It equals to the cumulative value that is provided by the organization. Experience Curve Effect: This concept was formulated in 1966 by Bruce Henderson. Experience is considered to be an asset for any organization. The concept promotes the increment of this asset in different forms in the organization, for example, hiring of experienced resources, collaboration with other companies etc. According to the experience curve effect; if a company gains greater experience in a specific field or production process then 25 to 30 % of the costs can be decreased. It can help the organization to evaluate the success rate of the company and increase revenues. BCG (Boston Consulting Group) Matrix: is a portfolio management model. It categorizes the products of the organization

Human Resource Management Essay Example | Topics and Well Written Essays - 2500 words - 19

Human Resource Management - Essay Example In response, a discussion of how HR managers can improve organizational performance through recruitment and selection, training and development, equality/diversity policies and employee involvement would be presented. All resources – man, money, methods, market, materials, minutes (representing time) and machines are the domain of general management. Human resources management solely involves man. Through and by men, the other m’s are acquired and utilized. The quality and utilization of the rest of the resources are almost always affected by decisions about and by human resources. Indeed, the accomplishment of the goals of an organization depends upon the availability and utilization of all these ingredients, the interaction of which, are people-caused. The acquisition, utilization and development of financial, material, technological and market resources which may be exhaustible are dependent on human resources. If the latter is available and capable, the other factors can be of great use to the organization. It is through people that they can be either harnessed and developed or dissipated and lost. Man does or undoes what exists; man creates or bypasses opportunities and scenarios. Hence, people power is the most significant and potent factor of all the resources available to an organization. An organization may start with zero funding, but with creative, resourceful, hardworking and honest people, it becomes financially viable. On the other hand, a plethora of financial and material resources in an organization may go down the drain if handled by an incompetent and dishonest staff. The significance of human resources in an organization has been emphasized by various scholars, to wit: Andres (2003: 48) averred that â€Å"the place of organizational objective is largely attributable to successful human resources management†.
