Leadership issues and solutions Essay Example | Topics and Well Written Essays - 250 words

Leadership issues and solutions - Essay Example Some of the complaints put forth include huge disparities between remuneration between those in top management and those in lower levels of operations. The working hours and increased work load per employee is also a challenge. The management needs to offer leadership by first listening and genuinely responding to these complaints. There is a communication gap that needs bridging where employees’ representatives should sit and negotiate with the management. Harmonizing remuneration needs to be considered and a formula devised on how to shorten the disparity. The workload will not be an issue if the management takes a few employees for further training so as to better manage the increased responsibilities. Organizations have to keep their employees motivated so as to ensure increased productivity states Camilius (2011). Camilius further states that losing employees is quite costly especially in replacing them. Every employee likes to feel valued and part of the larger organizational workforce. Even if some issues like increasing remuneration are sensitive and may not happen immediately, it is critical to communicate the intensions or reasons of failure thereof to the relevant employee representatives. These actions will go a long way in holding to the workforce as well as maintaining high motivation

Gender-Based Differences in Cardiovascular Disease (CVD) Research Paper

Gender-Based Differences in Cardiovascular Disease (CVD) - Research Paper Example As reported by the American Heart Association (2006), almost 70% of the total population of the United States has cardiovascular disease. As shown in the charts above (Health Care Online, 2011), males are more prone to develop CVD than women at the age below 60. Men die 10 years younger than women from heart attacks (Kannel et al., 1976). However, this biological advantage of women over men shrinks as they age. II. Biological Theories The primary biological advantage of women over men in terms of CVD risk is the female sex hormone, estrogen. Estrogen protects women from cardiovascular disease. Most of the protective functions of estrogen originate from its role in controlling cholesterol levels. This hormone works in the liver to eliminate unnecessary cholesterol in the body (Saleh & Connell, 2007). More particularly, estrogen boosts the level of good cholesterol and high-density lipoprotein (HDL) and minimizes the buildup of bad cholesterol or low-density lipoprotein (LDL). Bad chol esterol buildup blocks blood vessels which then can disrupt blood flow to the heart. In contrast, good cholesterol reduces these blockages by minimizing the level of bad cholesterol (Vitale, Miceli, & Rosano, 2007). Estrogen strengthens the prostacyclin receptor. The prostacyclin receptor, which soothes the production of vascular smooth muscle cells and minimizes pulmonary vascular disorders, is a primary goal for estrogen being controlled by the estrogen receptor proteins— ERa and ERb (Saleh & Connell, 2007). Prostacyclin receptor can hinder the tightening of vessel walls, blood clotting, and clustering of platelets (Sugden, 2001). Thus the protein can help protect the body from heart disease. Estrogen also prevents the development of dangerous blockages by working on white blood cells. These white blood cells can cause blockages by accumulating in the interiors of blood vessels (Sugden, 2001). Women in their childbearing years have higher amount of the protein annexin-A1 in their white blood cells compared to men. Annexin-A1 stops white blood cells from aggregating in the blood vessel wall which can cause vascular disorder (Sugden, 2001). Therefore, Pre-menopausal women are less prone to CVD than post-menopausal ones. Epidemiological studies reported lower CVD risk factors among estrogen-enriched women. These findings resulted in the assumption that estrogen-enhancing therapy, such as the use of birth control pills and hormone replacement therapy (HRT), for a specified period of time before the onset of the menopause is feasible. It is assumed that estrogens assume a major physiological function when the heart exhibits reperfusion disorder, which is an injury to the renal blood vessels (Saleh & Connell, 2007). Normally, estrogen activity is interceded by particular estrogen receptors (ERs). ERs are part of the primary group of steroid hormone receptor, which can function as endothelial nitric oxide synthase (eNOS), which serves a vital function in sus taining vascular homeostasis by combining and discharging a number of soothing elements, like prostacyclin (Saleh & Connell, 2007), with possible repercussions for coronary heart function. Nevertheless, the use of birth control pills has been linked to the raised amount of C-reactive protein related to CVD. This C-reactive protein (CRP) is generated in the body as a reaction to inflammation (Mendelsohn, 2002). Recurrently high CRP levels have been connected

Business Econimics - Research Paper Example The elasticity of demand might affected too: Since trust is hard to earn and easy to lose, it is likely that once a company has violated ethical standards, consumers will be afraid of getting burnt again and will avoid the company at the first sign of trouble, making their offerings more elastic. Costs might raise: Contractors, suppliers and distributors might ask for a higher price for their service and goods, either because they feel that the company's bargaining position has declined, as insurance against potential malfeasance, or as compensation for the inevitable PR hit. Ethical issues are more likely to occur in deregulated markets (Palast, 2002; Palast, 2004). This is for a few reasons. First: The kind of behavior that occurs in a deregulated market tends to already be less constrained by conventional ethics, meaning that companies that thrive in that environment are already likely to have unorthodox and perhaps unscrupulous cultures and practices. Second: Regulation, both by NGOs and government, tends to make companies more sensitive to the impacts of what they are doing; it might be seen by someone. One of the major ways that Enron managed to get away with so much was the inaction of shareholders and the failure of accounting firms, auditors and regulators (Palast, 2002; Berenbeim, 2002). Consider a rise in demand for computer chips and potato chips. Potato chips are pure luxury items: They are highly elastic, because people can afford to go without potato chips. Computers and the chips that make them up, in contrast, are essential items for business, homes, political agencies and NGOs. The economy runs on telecommunication technology, credit card processing, etc. that is all done through computerized systems. A reduction in demand can't hurt computer makers much, despite the relatively high cost of producing computer chips to potato chips, because they are so essential. In the short run, a potato chip maker might harvest more potatoes, run lines faste r, or pack factories more tightly to increase production. A computer chip maker might do the same thing, but while the occasional green or stale potato chip is not a threat to the potato chip makers' reputation, a failing computer chip costs headaches in bad reviews, tech support headaches and so on. Buying new factories for potato chips is likely to be easy: Buying and properly fitting new factories and training new personnel for computer chips is much harder. In the long run, of course, the potato chip company has to bear in mind that a new health fad, a change in the taste buds and palates of customers, a marketing campaign, or something else might harm the demand for their product. They can't afford to get too much excess. Further, potato chips must be strictly identified according to USDA standards, meaning rebranding is more difficult than it might seem and companies are less flexible than an initial review would suggest (2009). However, computer chip makers know that, in the long run, their product cannot help but grow, as the Third World catches up and computerizes more and more and as more and more products need computer chips. Thus, it's clear that a product that is elastic might have some more flexibility in dealing with spikes, but tends to have difficulty maintaining those spikes and therefore taking advantage of them, whereas a less elastic product might take longer to get

Role Of Education in Sustainable Development Essay Example for Free

Role Of Education in Sustainable Development Essay Sustainable development is that development which will meet the present needs of the community without compromising the ability of future generations to meet their own needs. Environmental education involves among other things the provision of information, recognizing values, clarifying concepts etc in order to develop skills and attitudes that enable the community to understand and appreciate the relationship between their cultures and their physical surroundings. At international fora, attempts have been made to promote environmental education. In the year 1975 in Belgrade, the program for international environmental education was started followed by the conference in Tsibilisi in 1977, Nevada 1979, Moscow 1987, †¦. . Since then the council of European countries has twice called on member countries to advance on environmental education in all sectors of education. There is required a dominant policy to ensure that the findings of research on environmental science are properly applied to ensure that the world is safe for further development with no further destruction of the natural resources. It is therefore necessary to involve the players in political, economic and cultural sectors in designing environmental programs. By doing this, we will notice that all these players have turned environmentalists and we can expect a conflict of interest of style in the approach of environmental matters. This is because sustainable development is a contested territory with its ownership disputed by forces with very diverse interests. Its thus difficult to foresee any slackening of the effort on those who will continue to impose development to suit their ends invoking â€Å"modernity, national integration, economic growth and other slogans† (Adams 1990, p199). With challenges as these, education is a must in order to bring these interests groups together and come up with sound policy on sustainable  development, infact one that is conscious of future needs. OBSTACLES TO SUSTAINABLE DEVELOPMENT There are various obstacles to sustainable development which include:- 1. Lack of awareness on issues involved, 2. Political unacceptability of obvious steps forward, 3. Opposition by groups with vested interests, 4. Inadequacy of institutional mechanism for integrating environment and development. SOLUTIONS To overcome these obstacles, there is a feeling among many groups that there is a need to replace the ideas and values that underlie the complex and visible obstacles with a new approach and reshaping of ideas and values. To do this we need not just a modification, but a total revolution of our thinking. This can well be achieved through a well-designed education approach. ROLE OF EDUCATION Education plays a major role in enhancing people’s awareness about bio-diversity conservation as well as sustainable development. It leads to actualization of conservation knowledge and skills which in turn help in broadening people’s knowledge about conservation, thus making them functional members of the society. Education will enlighten stakeholders on various issues relating to sustainable development and bio-diversity conservation. Also education will sensitize them to participate fully in campaigns against any act or development that threaten future sustainability. Consequently, education empowers stakeholders to take increasing charge of their own developments as key ingredients combined with a clear knowledge of environmental constraints and of requirements to meet basic needs. This enables people to understand their need for and importance of biodiversity for now and in the future. It is this education which will enable us realise  that sustainable development confronts not just society, but each of us at the heart of his or her purpose. It invites us to give practical support to the values of social equity, human worth and ecological health. Education questions our readiness to involve ourselves in the struggle for change, it challenges our willingness to contribute in greater measure to the activities of NGO’s and dedicated individuals who campaign on our behalf. Moreover, education asks us to accept that the small beginnings from which so many successful campaigns have started resides within ourselves. As Laszlo (1989) puts it, â€Å"we contemplate changing almost anything on this earth except ourselves,† and this is due to the inner constraints in our visions and values that can only be removed through education. This is because education will explain the need for and importance of attitude and behaviour change in our pursuit for development, as a result we will realise that we owe the future generations what we have today. It is education that will enable us reach a conclusion as Max-reef (1991,P113) explains: -â€Å"I have reached the conclusion that I lack the power to change the world or any significant part of it, I only have the power to change myself. And the fascinating thing is that if I decide to change myself, there is no police force in the world that can prevent me doing so. It is my decision and if I want to do it, I can do it. Now the point is that if I change myself, something may happen as a consequence that may lead to a change in the world†. As such awareness becomes more general, sustainable development will be regarded seriously by the people who really count not just elites but people generally. Education whether formal or informal has been proved to be a powerful tool in promoting changes in the attitudes and perceptions of people about a resource. A series of conferences under the auspices of UNDP have been held to address issues pertaining to the link between sound natural resource management and sustainable development, environmental conservation and improved human welfare. Education for sustainable development will not only create awareness of the  global crisis but must place it at the heart of the curriculum. It must be â€Å"ecological† rather than â€Å"environmental† encouraging broad holistic thinking, teaching the need for structural change and promoting the correct application of reductionist thinking to specific technical problems. It will embrace all the means of the change discussed in this paper and alert stakeholders to the feasibility of alternative practices. Further, education will not only inform stakeholders, but also allow them to participate in decision making process about biodiversity conservation and thus promoting change. Through education, stakeholders will not only become acquinted with one another’s vision about healthy ecosystems but also stimulates them to formulate their own visions relating to biodiversity. It will not only teach them about holism but will require them to think holistically. Holistic thinking is a particularly important means of change for sustainable development because it attempts to figure out the consequences. Holistic approach tries to anticipate the problem â€Å"simple† solutions, create and to identify more satisfactory structural solutions. Holistic thinking led one farmer in Kenya, sickened at having to shoot the elephants ruining his crops, to adopt an alternative form of land use, accommodating not only his own interest but also those of elephants, of tourists who wanted to see elephants and of local people who could supplement their subsistence economy with income from tourism. Education will also help us to see the need of putting people first in all our endeavours in sustainable development and biodiversity conservation. Putting people first means quite simply valuing people for themselves, for what they are rather than for what they can do, or how they can perform in the service of some interest whose ends may be quite radically opposed to the meeting of human need. Putting people first also means empowerment- a process by which those who are or feel excluded from decision making are enabled to participate in it. It involves the transfer of power from those in authority to smaller groups. In some countries this has to begin with establishing or re-establishing political rights and other basic freedoms. (A recent example is the return to free elections in Malawi and Kenya). Only  then can a start be made to provide education and training to raise awareness and allow stakeholders to play an effective role in political process. Empowerment also refers to what Paul Freire, the Brazilian educationist calls â€Å"Conscientization† or education for consciousness, by which communities and individuals become aware of the reasons for their poverty and oppression and begin to discuss what they themselves can do about it without enabling action by the authorities. Ecological education will not only teach about empowerment but will enable stakeholders to fulfil their aspiration by helping them to develop their full range of abilities. By paying equal attention to emotional and intellectual development, education will teach the basic life skills people need to establish identities and grow as individuals. By encouraging creativity, commitment and initiative, it will equip stakeholders to take responsibility for themselves and their future, and to avoid dependency on biodiversity without ensuring its sustainability through sound management practices. It will also focus on relationships and teach what Harrison (1990,p203) calls the â€Å"work of human communication of caring and nurturance, of tending the personal bonds of the community†. It is envisaged that well organised education will also enhance our ability to relate with each other, not just on the level of day to day communication skill, but more importantly by acknowledging others identities and rights to a resource. This education will initiate a process of lifelong growth in awareness and aspiration. An individuals readiness to participate in that process, at however lowly or rudimentary a level, will be more important than acquiring impressive qualifications, for as Paul Freire (1972) points out, we are all â€Å"unfinished† human beings with a commitment to improve â€Å"unfinished† reality. Without the opportunity to develop their potential, individuals can not develop fully in discussions and initiatives on which progress to more sustainable development depends. Therefore, properly resourced and directed education will ensure that all stakeholders become the beneficiaries of the care, concern and skills of others. CONCLUSION In a world where the challenge of sustainable development is an imperative, rather than an option, we can not afford to debar people from participating by making them feel failures, whether academic failures as a result of the rigid application of elitist standards, or social or personal failures as a result of inadequate evolutions of both their needs and their potential. Therefore, I envisage that properly resourced and directed education aimed at encouraging the development of sensitivity, awareness, critical thinking, problem solving and active participation in biodiversity conservation campaigns, will enable stakeholders not only to become aware of the issues and be able to act on that awareness, but will be equipped with the skills required to contribute effectively to the debate. They will learn to plan, organise, communicate with others, develop strategies and create alliances with an aim of promoting sustainable development and ensuring biodiversity conservation.

The System Level And The Programmer Level Information Technology Essay

The System Level And The Programmer Level Information Technology Essay Probably not, since any protection scheme devised by a human can also be broken and the more complex the scheme is, the more difficult it is to be confident of its correct implementation. As compared to dedicated machines, time-shared machines are far less secure, and are very easy to overload the buffers. They are also much slower to catch a virus. But in dedicated machine, all resources are available to the process being run. Q2) Under what circumstances would a user be better off using a time sharing system rather than a PC or single user workstation? Ans . When there are few other users, the task is large, and the hardware is fast, time-sharing makes sense. The full power of the system can be brought to bear on the users problem. The problem can be solved faster than on a personal computer. Another case occurs when lots of other users need resources at the same time. A personal computer is best when the job is small enough to be executed reasonably on it and when performance is sufficient to execute the program to the users satisfaction. Q3) In the designing of the operating system there are two approaches modular kernel and layered approach? How are they different? Ans. There are various differences between moduler kernel and layered approach:- A modular kernel differs from a layered approach in that there is less overhead in making a call to a lower level part of the kernel. The call doesnt have to jump through numerous layers before work gets done and parts are aware of any other parts of the kernel and not just what is below them. Modular kernel is more secure as compared to layered approach, as more operations are done in user mode than in kernel mode. Debugging and modification of data is much easier in layered approach because changes affect only limited sections of the system rather than touching all sections of the system. In modular kernel approach, kernel design and its functionality are more simple as compared to layered approach. Part B Q4) There is guest operating system and a host operating system like VMware? List all the factors in choosing the host operating system? Ans. A host operating system is the operating system that is in direct communication with the hardware. It has direct hardware access to kernel mode and all of the devices on the physical machine. The guest operating system runs on top of a virtualization layer and all of the physical devices are virtualized. A host operating system should be as modular and thin as possible to allow the virtualization of the hardware to be as close to the physical hardware as possible, and so that dependencies that exist in the host operating dont restrict operation in the guest operating system. Q5) The kernel is responsible for a action with the processes. Search through the action of kernel and describe what is the action? Ans. The various actions of the kernel are as follows: The main task of a kernel is to allow the execution of applications and support them with features such as hardware abstractions. To run an application, a kernel typically sets up an  address space  for the application, loads the file containing the applications code into memory, sets up a  stack  for the program and branches to a given location inside the program, thus starting its execution. The kernel uses  scheduling algorithms  to determine which process is running next and how much time it will be given. The algorithm chosen may allow for some processes to have higher priority than others. To perform useful functions, processes need access to the  peripherals  connected to the computer, which are controlled by the kernel through  device drivers. If sometimes the interrupt has been occurred during execution of any process then it saves the state(address) of current process, and after that when interrupt has been removed then it restores the state(address) of previous process. Q6) Considering both the system level and the programmer level. Consider the advantage and disadvantage of the following structure. Synchronous and asynchronous communication. Automatic and explicit buffering. Send by copy and send by reference Fixed-sized and variable-sized message. Ans: Synchronous and asynchronous communication- synchronous communication: Advantage:   you can get an immediate response; instant feedback fosters communication; there seems to be a more emotional bonding effect between people when there is a possiblity to communicate in real time (synchronously), spontaneity. Disadvantage: There is less time to think about what you want to say or your response to another; time may be a limiting factor, e.g time zones; synchronous communication over the computer may be difficult because of the speed of data transaction with slower connections; you need extra equipment (speakers, microphone, webcamera). asynchronous communication: Advantage: you have time to think about what you want to say; time is not a constraint. You can receive the message whenever you have time and you can analyze the content of the message more carefully so the answer you give can be even more meaningful because it has gone through a process of elaboration. Disadvantage: no immediate response, especially where time is significant; you may not know if the other person has received your message; the message loses human contact . Automatic and explicit buffering Automatic buffering : Advantage: Automatic buffering provides a queue with inde ¬Ã‚ nite length ; thus ensuring the sender will never have to block while waiting to copy a message. Disadvantage: There are no specifications how automatic buffering will be provided; one scheme may reserve sufficiently large memory where much of the memory is wasted. Explicit buffering: Advantage: Explicit buffering speci ¬Ã‚ es how large the bufferis. Disadvantage: In this situation, the sender may be blocked while waiting for available space in the queue. However, it is less likely memory will be wasted with explicit buffering. Send by copy and send by reference Send by copy: Advantage: send by copy is better for synchronization issues. Disadvantage: Send by copy does not allow the receiver to alter the state of parameter. send by reference: Advantage: A bene ¬Ã‚ t of send by reference is that it allows the programmer to write a distributed version of a centralized application Javas RMI provides both, however passing a parameter by reference requires declaring the parameter as a remote object as well. Send by reference also allow the receiver to alter the state of parameter. Disadvantage: send by reference can compromise the security of an organisation because sensitive information can be easily distributed accidently or deliberately. Fixed-sized and variable-sized messages Fixed-sized messages: Advantage: The implications of this are mostly related to buffering issues; with  ¬Ã‚ xed-size messages, a buffer with a speci ¬Ã‚ c size can hold a known number of messages. Disadvantage: with  ¬Ã‚ xed-sized messages the messages are copied from the address space of the sender to the address space of the receiving process. Variable-sized messages: Advantage: variable-sized messages (i.e. Larger messages) use shared memory to pass the message. Disadvantage: The number of variable-sized messages that can be held by such a buffer is unknown.
