Leadership and Management Essay Example | Topics and Well Written Essays - 750 words

Leadership and Management - Essay Example With the definition on hand, it can be inferred that there are differences and similarities present in leadership and management. Specifically, the main similarity of leadership and management is that both aim for long term positive results. With this, leaders and managers put more weight on the intangible aspect of the organization, such as the vision and mission of the organization. They also look beyond the boundaries of the organization and influence people outside and within the organization. Also, they both act as the link between the followers and the head management while both greatly depend on the followers (R.C Swansburg and R.J. Swansburg 405). On the other hand, leadership and management also exemplify differences. In the context of management, it is the execution of the ability and task of the administrator to control, coordinate, organize, and plan for the organization. Management is the ability to foresee events and plan for such events. Organization in management also means linking the structure and manpower in order to execute the plans. In addition, managers must have the intellectual capacity and principles to be objective on tasks and decisions. Therefore, management is the act of accomplishing the objectives and the goals of the organization by efficiently using the available resources. ... Influence is what drives the relationship of a leader and a follower. Also, with the influence, leaders are able to attain the trust and confidence of their followers. In addition, a leader is effective when he or she influences his or her followers to be ethical in their work and conduct within and outside the organization. For this to occur, leaders must equip their members with the direction that aims toward the goals and objectives of the organization. With the appropriate direction and influence, leaders will be able to create change for the betterment of the organization. Effective leaders are able to realize the need for change and are capable of executing the change needed. Leaders are considered as risk takers and open minded individuals who are willing to take the challenge. Moreover, in totality, leadership can be summed up to the person’s ability to lead people towards a specific goal or change. Leaders are people who are comfortable and enjoy working with follower s (Lussier and Achua 7-8). Moreover, it is vital to note that a leader is important in an organization because a leader is one of the most essential factors that lead an organization to succeed. Also, companies and organizations must mold their own leaders, and build home-grown leaders that are rooted to maneuver the organization towards success. With this on hand, leaders are very important in any industry or organization. In relation to this, it must be noted that leaders are not born or made, but leaders are born and made. It is vital to understand that effective leaders already have the innate ability to lead people; however, these abilities must be enhanced and developed in order for it to be effective. Nonetheless, this does

Cancer and what if cancer is cured Term Paper Example | Topics and Well Written Essays - 2250 words

Cancer and what if cancer is cured - Term Paper Example The uncontrollable growth of cells results in formation of malignant tumors. The cells divide and grow fast to invade surrounding body parts as the growth enlarges and expands. Some cancerous growths spread to other very distant places on the body through the blood stream or the lymphatic system. It is worth noting that not all tumors and growths on the body are cancerous. Benign tumors for instance do not spread all over the body or invade body tissues near them. As of today, there are about 200 known types of cancerous infections that inflict human beings. The cancerous growths are often very harmful to and affect the normal functioning of the human body. After a cancer infection, one’s body loses control over the growth of the cells which begin to divide and split and enlarge. Healthy and normal body cells often split and divide from time to time as they create other healthy cells in the body. This process however has been used to facilitate the growth and spread of cancero us cells once one becomes infected. The cancerous cells divide and recreate themselves as they make other copies of themselves leading to more cancerous cells. The process goes on as the tumors enlarge and expand to the nearby parts. These cancerous growths usually make the victim uncomfortable and in some cancers, it is usually very painful. Metastasis is a process that enables cancerous cells to spread to other body tissues. Metastasis involves cancerous cells moving through the blood stream of the lymphatic system. This process of spreading cancer cells to other body parts is often referred to as metastasizing. In developed countries, cancer has been recognized as the biggest cause of death. In some cases it has been compared to HIV/AIDS in developing countries especially in the early 90’s. It has become one of the most researched diseases in the world today with most studies focusing on prevention and cure, as well as early detection among other aspects of the dreaded dis ease. Cancer can affect anyone irrespective of their age. A majority of the cancer infections however mostly affect people as they tend to grow older (Kinzler & Vogelstein, 2002). The reason for this is that as an individual grows older, their DNA gets old too. This results in the DNA being damaged, or any other damage that may have happened before may get worsen the situation as one grows older. There are also other types of cancer that are more common among young people than the old. Testicular cancer, also known as cancer of the testicles, for instance is more common among young males than among older men. Cancer is caused by a wide range of complex and diverse issues, most of them have only been understood partially with studies going on to determine the specific causes. The few universally acknowledged causal agents of cancer include exposure to radiation, obesity, tobacco, environmental pollutions, other dietary factors and lack of adequate physical activity. All these factors damage body genes leading to development of cancerous cells. They can also combine with other factors in the body to damage genes and cause cancer to victims through mutations on various body parts that will spread to other parts throughout the development of the disease. About 5-10% of cancer infections occur as inherited genetic defects from cancerous infections that run down through

Enhancing Cyber Situational awareness through Active Defence Research Paper

Enhancing Cyber Situational awareness through Active Defence - Research Paper Example They include: i. Visualization of Situation Awareness data/ information ii. Metrics iii. Dynamic Risk Assessment for Mission Assurance However, Cyber Situation Awareness is still considered a new field of research that made its mark with Denning’s (1987, 2002) pioneering work on using expert systems to detect computer attacks in 1987, followed by a plethora of experiments thereafter. The early stage of experiments shaped the concept of tactical fusion, which was proposed by the JDL (Joint Director’s Laboratory) model in 1992. This model contains five functional levels such as 0, 1, 2, 3, and 4. It was published by Hall, and Llinas (1997). It focused solely on data management to prevent cyber attacks. In it, most of the tasks are concentrated on level 0, 1, and 4. Tadda finds JDL model as a bottom-up, data driven model (Figure 3). The significance of JDL model lies in the fact that it highlights the significance of algorithmic techniques towards supporting situation awar eness (Salerno, Hinman, & Boulware 2005). Figure 3: Tactical Fusion/JDL Model [Adapted from (Tadd 2008)] Explanation From a simple point of view, SA refers to the knowledge about ongoing events in the cyber environments. According to Ensley (2000: 3), SA defines three essential drivers which include perception, comprehension, and projection. As per Ensley, perceptions of cues (which he refers to as Level 1 SA) are fundamental, since in the absence of basic perception of important information the chance of wrongly visualizing the situation drastically increases. In support of this argument she cites a finding that showed 76% of SA errors of the pilots emanated from lack of perception of the required information (Jones & Ensley 1996). Comprehension on the other hand, refers to an outcome of how people interpret, associate, store, and retain information, and thus makes its place in SA process as Level 2 SA in Ensley’s (1995c). The Level 3 SA, i.e., Projection helps operators to perform at the highest level of SA, since it enables the operators to forecast on situation events and its dynamics, Ensley (2000). Ensley further explains that SA is all about â€Å"knowing what is going on,† while from a formal point of view it is all about â€Å"the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning and the projection of their status in the near future† (Ensley 1995b: 36). In a nutshell, Ensley consolidated the theoretical perspective of SA by adding human factors in it, thereby opening a new horizon of developments towards achieving quality SA (Wickes 2008: 397). Endorsement of the above view from a host of researchers (Ensley 1993, 1994; Ensley & Rodgers 1994; Ensley & Robertson 1996; and Endsley et al. 1998) highlighted the temporal aspects of time, as the above view showed that both perception of time and temporal dynamics associated with events play crucial roles in the formulatio n of SA, and a critical part of SA involves understanding of the amount of time available in the occurrence of an event or in the course of an action. Such developments helped researchers to underpin time as an integral part of Level 2

Cross cultural management Essay Example | Topics and Well Written Essays - 1750 words

Cross cultural management - Essay Example The key messages that the author has tried to suggest in this article are that cross-cultural perception between supposedly similar groups in terms of similarity of national culture varies on the basis of the context in which the cooperation occurs between the groups (Heijes, 2011). The author asserts that power dynamics between different ethnic groups is one of the most fundamental drivers of the cross-cultural perception. Research along this line is a valuable aid that extends the understanding of the significant interrelationship between the culture and dynamics of power within organizations. The distinctive content of the article is that the author has achieved his objectives by compiling a comparative evaluation of the cross-cultural perception between two different ethnic groups. In the recent years, the number of cross-national studies has considerably increased, of which this research forms a part. The organizational research’s domain is getting increasingly internatio nal, thus raising concerns about the transportability of the models of social science across societies.The ethnic groups selected for the study were African Curacaoans and European Dutch. These groups were chosen in two organizations that operated in two different countries and the power dynamics of the selected organizations in their respective environments differed from each other. The author has used empirical evidence to demonstrate the way cross-cultural perception is influenced by differences of power. Â  ... Research along this line is a valuable aid that extends the understanding of the significant interrelationship between the culture and dynamics of power within organizations. The distinctive content of the article is that the author has achieved his objectives by compiling a comparative evaluation of the cross-cultural perception between two different ethnic groups. In the recent years, the number of cross-national studies has considerably increased (Renn and Rohrmann, 2000, p. 20), of which this research forms a part. The organizational research’s domain is getting increasingly international, thus raising concerns about the transportability of the models of social science across societies (Tsui, 2004). The ethnic groups selected for the study were African Curacaoans and European Dutch. These groups were chosen in two organizations that operated in two different countries and the power dynamics of the selected organizations in their respective environments differed from each o ther. The author has used empirical evidence to demonstrate the way cross-cultural perception is influenced by differences of power. Perception has been studied along two altering axes; the first of which was the external national context and the second was the internal organizational context. The author has studied the cross-cultural perceptions in Curacaoans and Dutch as well as in two organizations that were made part of the research; the police and the Internal Revenue Service (IRS). The author used these comparative case studies to offer a comprehensive account of the real-life cross-cultural perceptions between the selected ethnic groups so as to comprehend

Nature of an electron Coursework Example | Topics and Well Written Essays - 2250 words

Nature of an electron - Coursework Example This is described in a classical wave model of light; which states that light properties that are similar to any wave. For instance, light experiences reflection and refraction in the same manner that any other wave would experience interference. In addition, light experiences the Doppler effect the same way any other wave would experience Doppler effect. However, the prediction of the quantum model shows that frequency or wavelength of the incident of the incident light only affects the photoelectric current. where E- is the energy that the quantum light produces, Kmax is the maximum kinetic energy of the photoelectrom emitted , where as Wo is the work function of the of the energy needed to innitiate the emision of photoelectrons from the metal surface. In an experiment to demonstrate the photoelectric effect, the following apparatus are required: a digital voltmeter to be used to measure the reverse voltage reading, a photodiode connected with an amplifier, monochromatic light sou rce to produce light beams to irradiate the photo cathode, and a filter to neutrally vary the intensity of light. Generally the quantization energy of the electromagnetic radiation in light is given in the relation, where the radiation energy, is a constant known as the Plank’s constant and is given as (6.63?10^-34Js), and - is the frequency of the light incident energy. The validity of the equation is based on the photoelectric effect experiment. There are four aspects that need to be taken into consideration when conducting the photoelectric effect experiment. These facts include: the minimum frequency; when the frequency of the incident light is less than the minimum frequency required, no photoelectrons can be emitted despite the intensity of the light. The value of minimum frequency varies from metal to metal. Secondly, as the frequency of the incident light increases, the kinetic energy of the photoelectrons increases. However, the intensity of the light is independent of the kinetic energy of the electron emitted. And lastly, the emission of photons is effectively instantaneous. (physics 242 laboratory manual) The photoelectric effect experiment consists if a high intensity lamb, a phototube, and batteries. The photodiode tube is the central element of the apparatus. The window in the diode gives way for light into the tube to the clean metal surface at the cathode. The diode is completely evacuated to avoid any collision of air molecules and the electrons. When beams of light hit the surface of the metal plate at the cathode, electrons are emitted by the metal plate. The photodiode has an in-built capacitance developing a voltage during the charging process by the electrons emitted. When the stopping potential of the cathode is reached, the difference in voltage across the two poles, that is, cathode and anode stabilizes. A very sensitive amplifier is used to measure the stopping potential. The amplifier aids in the establishment of the small nu mber of photoelectrons emitted. A voltmeter is used to measure the output voltage of the between the batteries and the output ground terminals. A number of different monochromatic light beams are used for the experiment. A glass tube consisting of mercury vapor produces light when discharged electrically. The glasses envelop filters out the ultraviolet light that can be harmful. The mercury light produces five thin spectral lines that are: yellow, green blue, violet, and ultraviolet in the visible region. These lines can be spatially separated by diffraction. The wavelength desired is selected using a collimator, and the intensity of the selected wavelength is varied using a density filter The mercury lamb is switched on. On the front reflective mask of the lamb box, yellow, green, and tiny rays of blue

Implementing Electronic Health Record innovations for Pressure Ulcer Essay

Implementing Electronic Health Record innovations for Pressure Ulcer Prevention and Management - Essay Example Regardless of the size of the project, the proper integration of a skilled workforce, proven strategies and technology at MICU, would see the successful implementation of the program in various units for easy use by clinicians. If properly utilized, EHR can be the silver bullet to the problem of inconsistencies that are the order of the day in documenting pressure ulcer management processes through paper-work. Prevention of Pressure Ulcer According to Hagens and Krose (2009), to maximize the benefits the EHR for Pressure Ulcer prevention and management, it would be vital to keep problem lists, medical prescription lists and sensitivity lists in all units handling the patients s(National Pressure Ulcer Advisory Panel, 2007). In the MICU case, medical assistants or skin care specialists should enter medications and sensitivities from the paper work, and physicians would enter the problem lists. It would be appropriate to enter data shortly before an appointment is due, and take the cha rt to scanning. In doing so, the pressure ulcer management units will have an entirely electronic chart ready for patient handling when the patient arrives at the units (Kerr, 2009). Alternatively, it would be appropriate to enlist registered nurses for the task of problem list entry before the program is ready for use by various clinicians. Assessment for Pressure Ulcer For acute care, the first assessment should be carried out on admission and after every 1-2 days or whenever the condition of the patient changes (Clarke, Bradley, Whytock, Handfield, Van der Wal, & Gundry, 2005). At MICU, the system would be programmed to notify the health care providers to do assessments every 24 hours. For home health, the first assessment would be carried out on admission, and re-examination done as soon as the patient resumes care, during recertification, refer or release, or whenever the patient’s health condition changes (Adler, 2010). At MICU, it would be appropriate to reassess the p atient’s condition at each nursing visit. And for long-term care in MICU, the initial screening for patients would be appropriately done on admission and every week during subsequent missions. Determining Risk Levels Several electronic tools for risk assessment are accessible to assist in predicting the level of risk of the disease (National Pressure Ulcer Advisory Panel, 2007). They include machines with values that when summed up together, can enable the health care providers to determine the risk score in totality. The Braden and Norton Scales are proven tools that can be used to provide an electronic data for predicting the risk of pressure ulcer risk in MICU. According to Ayello, Capitulo, Fife, Fowler, Krasner, Mulder, Sibbald, and Yankowsky (2009), these tools help clinicians to determine the risk values, which eventually can lead to the formulation of the most appropriate and opportune medical interventions. Norton Scale The Norton Scale comprises five groups: physica l and mental conditions; mobility, activity, and incontinence. These factors are valued from 1– 4 (Tavenner, & Sebelius, 2012). The total values usually range from 5 to 20. An entry of the following data to the EHR system can help clinicians to cope with the condition in a more effective and faster way: Mild Risk values at 14: Moderate Risk at 13: and High Risk at 12. The scale should be credible and kept in such condition to avoid errors in the final readings of data (Liang, 2007). Any alterations can change or render it an

How Life Can Be Changeable and Incredibly Frenzied Essay - 4

How Life Can Be Changeable and Incredibly Frenzied - Essay Example It was until his condition became worse that he qualified for palliative care and a number of nurses as well as social workers could attend to him. His conditions included pneumonia and caused his chest to grow wheezy. This disease was identifies as the best friend for my father since it offered an opportunity for slow death. Butler’s entire essay depicts a literal and emotional piece especially since it is about the slow death of her father. Bridget Potter in her essay ‘The lucky Girl’ describes her endeavors as she tries to get rid of an unwanted pregnancy during the eras when it was illegal. She uses her story to explain the dangers that women had to undergo prior to legalization of abortion in America. In her story, she points out most people especially women seeking for abortion lack any other option in mind even if realistically adoption is an option. This is the reason she has to beg the doctors to claim her condition as necrotic so that she would undergo t he process of abortion in a hospital. Performing illegal abortions can cause unnecessary deaths and for this reason, it would only be fair to let women choose affordable, safe and legal methods of abortions. In the essay ‘Topic of Cancer’, Christopher Hitchens provides information about his struggles with esophagus cancer. He confirms that a number of times, he had woken up feeling like death, but it did not feel as it did when it was confirmed that he had the cancer illness. In his description, he explains that he felt like he had manacled to his own corpse. In his essay, it is essential to identify the intellectual rather than the emotional bit since it actually dominates his entire writing. The theme of death and suffering that accompanies it are very evident in this essay as Hitchens describes the pain he felt from his thorax and chest. An individual listening to his description can picture the breathing struggles he had to endure, and as he explains how the above p arts appeared to have emptied out and then replenished with cement that was slowly drying. Breathing is the ideal meaning of life since difficulties in breathing result to much negativity such as excessive beating of the heart and strenuous efforts in doing simple things like breathing and walking. According to Hitchens, emergency individuals are kind hearted, engage professionalism and courtesy, and the ability to save lives. Those used in the essay that assisted Hitchens carefully worked on his heart and lungs guaranteeing that he did not have to put up with death. In the three essays, sickness and death are common themes although is one of the essay, the Lucky Girl, the condition is not really sickness. Hitchens’s and Butler’s essay provide a clear analysis of the differences of the employees in hospitals. The emergency crew in Hitchen’s essay is very humble and passionate and treats him with great care to the extent that his treatment is fruitful: resulting to his survival. On the other hand, the nurses providing medication for Butler’s father were ignorant and did not identify the causative disease for her father’s death. If they would have identified the initial signs of pneumonia, they would have had a reason to hospitalize him and offer him the required treatment. Similarly, Potter shows the kind of attitude that Doctors have towards assisting some of the patients who are in great need.
