The Tomb Of Tutankhamen Essays - Egyptian Gods, Egyptian Mythology

The Tomb of Tutankhamen The Tomb of Tutankhamen What does the tomb of tutankhamen and its contents show about the Egyptian concern for the afterlife? Tutakhamen's tomb, and the artifacts inside are an indication of the concern the Ancient Egyptians held for the after-life of their king. In 26th Nov. 1922, the English archaeologist Howard Carter opened the virtually intact tomb of a largely unknown pharaoh: Tutankhamen. This was the first, and to date the finest royal tomb found virtually intact in the history of Egyptology. It took almost a decade of meticulous and painstaking work to empty the tomb of Tutankhamen. Around 3500 individual items were recovered. When the Burial Chamber of Tutankhamen was officially opened, on 17 February 1923, the Antechamber had been emptied. It had taken near fifty days to empty the Antechamber; the time required to dismantle and restore the contents of the Burial Chamber including the gilded wooden and the sarcophagus was to be greater, and the work was not completed until November 1930, eight years after the original discovery. One must examine both the tomb itself, and its contents, to see the connection between the tombs and burial rituals and the doctrine of eternal life. The royal tombs were not merely homes in the hereafter for the kings, as are the private tombs of commoners and nobility. Instead the tombs are cosmological vehicles of rebirth and deification as much as "houses of eternity." As the king is supposed to become Osiris in a far more intimate way than commoners, he is equipped with his very own Underworld. And as the king is supposed to become R in a way entirely unavailable to commoners, he is equipped with his very own passage of the sun, whether this is thought of as the way through the underworld or through the heavens. Tutankhamon's tomb, hurriedly prepared for the premature death of the king at the age of only about 18, is, as Romer says, a "hole in the ground," compared to a proper royal tomb. The theme of fours is conspicuous in Egyptian religious practice. Tutankhamon's tomb contains four chambers. The burial chamber, with a ritual if not an actual orientation towards the West, is the chamber of departure towards the funeral destinies. The internment of the body certainly is the beginning of the sojourn of the dead, and the Egyptians saw the dead as departing"into the West." The room called the "Treasury" is then interpreted to have a ritual orientation towards the North as the "chamber of reconstitution of the body." Since the most conspicuous object in the Treasury was a great gilt sledge holding the shrine containing the canopic chest, which holds the king's viscera, this could well suggest the problem of reassembling the king's living body. That task, indeed, has a very important place in Egyptian mythology. After the goddess Isis had retrieved her husband Osiris's murdered body from Byblos, their common brother, Seth, the original murderer, stole the body, cut it into pieces, and tossed them in the Nile. Isis then had to retrieve the parts of the body before Osiris could be restored to life. Her search through the Delta, which is in the North of Egypt, seems to parallel the "sacred pilgrimage" to cities of the Delta that Desroches-Noblecourt relates as one of ritual acts of the funeral, as many of the other objects in the Treasury seem to be accessories for that pilgrimage. For the sovereign to be reborn it was necessary that a symbolic pilgrimage be made to the holy cities of the delta. The principal halts of the journey corresponded almost exactly to the four cardinal points of the delta where these cities were situated. Sais, to the west, represented the necropolis where the body was buried; Buto to the north, with its famous canal, was an essential stage of the transformations within the aquatic world of the primordial abyss, evoking the water surrounding the unborn child; and Mendes to the east whose name could be written with the two pillars of Osiris, the djed pillars, evoking the concept of air. There, said the old texts, the gods Shu and Tefenet were reunited, or again, according to the 17th chapter of The Book of the Dead, that was where the souls of Osiris and Re had joined. Finally, the southern-most city which completed the cycle of Heliopolis, the city of the sun, symbolizing the fourth [sic] element, fire, where the heavenly body arose in youth glory between the two hills on the horizon. [Christiane Desroches-Noblecourt, 1963, p. 238-9] As these four cities parallel the four rooms

Ethical Standards. Ethical StandardsMoral and ethical aspects of human life are very important for the personal development and statement. These life values determine attitude towards people, God and family. They are not regulated by law or other governmental documents, and there is no determined punishment for their violation, but still breaking ethical rules means breaking own personality and acting against oneself. 1. Ethical standard in majority of cases is taken from the parents’ family, social life, religion and historical period. Also, some people think that social groups, mentality and corporate culture, make impact on ethical standards formation. In other words, it is possible to consider the social environment as a major factor, which influences the ethical and moral standards of the personality. 2. According to the respondents’ point of view, those standards of personal ethics, which were grounded by parents in the childhood, are completely impossible to change because personality makes all important life decisions and actions, according to these standards. In some cases, it is possible to make some impact for the personal ethics while changing environment and religious- person would have to adapt to the new life conditions and to the people, surrounding him or her with their life principles. 3. In most cases ethical standards consider God as the main judge of all our actions. The God is also represented for many people as the personal example on how people should live and act. Family values are the core principle of ethics and people think that it is impossible to be fair with him/herself without being fair in own family. Parents, kids and beloved are the sense of life. Belief in afterlife time – one more important issue in following all ethical norms and standards. Respondents consider the afterlife time as the remuneration for the fair and faithful life, for acting, according to the ethical norms. References: Auditing Practices Board (2010) Ethical Standards.

Concept Analysis Research Paper Example | Topics and Well Written Essays - 2000 words

Concept Analysis - Research Paper Example Fortunately, these are steadfast and always find a place for the duty of care as this form the tenets of their profession. This is the place of nursing in our contemporary set up. The importance of those in the profession is largely ignored by the public and their value is only recognized when one is need of their expertise. It is this maligned nature of the profession that has strengthened the call for â€Å"the heart of nursing†. The heart of nursing is an apparent reference to a set of qualities that a nurse needs to discharge their duty in oblivion of the external factors that would otherwise affect successful discharge of commensurate duties. This is a key part of ensuring successful delivery of nursing care in light of pandemic ailments affecting the world populace (Schnatz, 2007). In trying to understand nursing and what it encapsulates we must try to look at the underlying enablers of nursing care. It should be noted that nursing as a practice is as strongly reliant on professional education as it is on human duty and obligation to care for others. Notably, in primitive societies where the decision to be a nurse (caregiver) was made on behalf of a person at birth the successful discharge of nursing duties was still possible. ... In the midst of these informal means of gathering nursing expertise the sole or the basic drive was the willingness to care given the plight of patients. The fact that nursing has been existent since antiquity and the knowledge that the first formal nurse training school was established in 1872, nurse training school of Women’s Hospital of Philadelphia, further underlines the duty for care or compassion as the most fundamental aspect in nursing (Egenes, 2010). Method of concept analysis and why this method was chosen In discussing compassion as nursing’s most precious asset or as the most dominant altruistic ideal in nursing care this study adopts Chinn & Kramer’s (1991) approach to concept analysis. Chinn & Kramer (1991) identify the purpose of their concept analysis approach as â€Å"producing tentative definition of the concept and a set of tentative criteria for determining if the concept ‘exists’ in a particular situation (88). Under this appro ach the first step is selecting the concept, clarifying the purpose, identifying the sources of data, exploring context and values and formulating criteria. Data sources Data to be used in the concept analysis will be derived from existent studies on nursing care and specific review of compassion and compassionate care as a key ideal in nursing. A host of this information is published in peer reviewed journals and professional websites which have sought to explain and research on nursing. Equally important will be historical data on the place of nursing in our society as well as the foundations and prerequisites of being a successful care giver. In essence, this analysis envisions that successful care giving as a factor is determined by the compassion of the care

Outline - Essay Example In other words, I need to address a lifestyle change that is responsive to my desire to curtail irresponsible spending. This question is very important to me because I realize that in order to improve the quality of my life I need to be more budget conscious and more responsible with what I do with my earnings. This is all the more important because my irrational and irresponsible spending impacts not only my own comfort, but the comfort of my family. At this point I am able to admit that I am at worst a compulsive spender, at best, unable to manage my earnings responsibly. I want to make a lifestyle change that reverses this conduct and improves the quality of my life and the lives of my loved ones. In this regard, I have focused my attention on what it is that I need to do to invoke an effective lifestyle change to curtail my spending habits. Current research into the topic of lifestyle changes typically agree that lifestyle change commences with identifying future goals and acknowledging current personal obstacles that can be changed to achieve a successful lifestyle change. McGraw (1999) informs that lifestyle changes begin with a realization that everyone faces challenges but the individual must take sole responsibility for meeting their own challenges (pp. 11-12). In general there are ten life laws for lifestyle changes. They are: becoming one of those that get it; accept that you are responsible for your own life; do that which works; accept what needs to be changed; take positive action; identify your perceptions; take control of your life; dictate how you are treated; be merciful and identify what you want to achieve (McGraw 1999). Markway et al (2003) caution that making lifestyle changes are never easy as it requires commitment, vision and discipline (p. 92). Tracy (2009) maintains that success driven persons are those who think ahead to the future and do not

Philosophy of healthcare in USA Essay Example | Topics and Well Written Essays - 250 words

Philosophy of healthcare in USA - Essay Example The target population includes the elderly especially the chronically ill older patients, children, and unemployed or underemployed people. Much attention has been given to older people because of their poor health and it is estimated by 2050 thirty percent of the population in USA will consist of elderly people. It is estimated that over 45 million people in USA are either uninsured or underinsured (Papadimos, 2007). This means that access to quality healthcare is little or none. In some instances political agendas have resulted in creating healthcare programs that are ineffective. This has downplayed the importance of better healthcare services to the population. The quality and appropriateness of healthcare services impact heavily on costs. The insured have access to better healthcare services than those uninsured. This means the uninsured and those unemployed or underemployed access cheap healthcare services that may be poor in quality. The government should make sure that all people have access to quality healthcare regardless of their socioeconomic status. Health insurance policies should at least cover the most vulnerable people in the population. Programs proposed by the Congress should be workable and

Slack Bus And Slack Generator

Slack Bus And Slack Generator The Table below shows input data of each busbar in the system used to solve the power flow and the simulation result according to instruction described in question 1. BUS Input Data [Simulation Result] BUS 1 pu P (load) 100 MW Q (load) 0 Mvar BUS 2 P (load) 200 MW Q (load) 100 Mvar CB of Generation Open BUS 3 1 pu P (Gen) 200 MW P (load) 100 MW Q (load) 50 Mvar AVR On AGC Off Slack bus and slack generator In power flow calculation, unique numerical solution cannot be calculated without reference voltage magnitude and angle due to unequal number of unknown variables and independent equations. The slack bus is the reference bus where its voltage is considered to be fixed voltage magnitude and angle (1à ¢Ã‹â€ Ã‚  0 °), so that the various voltage angle difference among the buses can be calculated respect. In addition, the slack generator supplies as much real power and reactive power as needed for balancing the power flow considering power generation, load demand and losses in the system while keep the voltage constant as 1à ¢Ã‹â€ Ã‚  0 °. In real power system, when relatively weak system is linked to the larger system via a single bus, this bus can represent the large system with an equivalent generator keeping the voltage constant and generating any necessary power like slack bus. [1] Bus type (PQ bus or PV bus) BUS Bus type Comments BUS 2 PQ Bus Generator is disconnected to Bus 2 BUS 3 PV Bus Generator is connected to Bus 3 and the magnitude of voltage of generator keep constant by using AVR In general, each bus in the power system can be categorized into three bus types such as Slack Bus, Load (PQ) Bus, and Voltage Controlled (PV) Bus. The definition and difference between PQ Bus and PV Bus are described as follows; [2] PV Bus (Generator Bus or Voltage Controlled Bus): It is a bus at which the magnitude of the bus voltage is kept constant by the generator. Even though the bus has several generators and load, if any generators connected to the bus regulate the bus voltage with AVR, then this bus is referred to PV Bus. For PV bus, the magnitude of the bus voltage and real power supplied to the system are specified, and reactive power and angle of the bus voltage are accordingly determined. If a preset maximum and minimum reactive power limit is reached, the reactive output of the generator remains at the limited values, so the bus can be considered as PQ Bus instead of PV Bus. [2] PQ Bus (Load Bus): It is a bus at which the voltage is changed depending on total net real power and reactive power of loads and generators without voltage regulator. Therefore, in the power simulation and calculation, the real power and reactive power of the loads are specified as input data and accordingly the voltage (magnitude and angle) is calculated based on the above input. The following table specifies input and output of each bus type in the power system simulation and calculation. Bus Type P Q (Magnitude) ÃŽÂ ´ (Angle) PQ Bus Input Input Output Output PV Bus Input Output Input Output Slack Bus Output Output Input Input System Balance Total Generation Load Demand BUS Real Power (MW) Imaginary Power (Mvar) Generation Load Generation Load BUS 1 204.093 100 56.240 0 BUS 2 0 200 0 100 BUS 3 200 100 107.404 50 Total 404.093 400 163.644 150 Difference Pgen Pdemand = 4.093 Qgen Qstored in load = 13.644 Reason: Real power loss due to resistance of transmission line and imaginary power storage due to reactance of transmission line are the reasons for the difference between power generation and load demand in the system. P (Losses) Q (Storage) over the transmission line BUS Real Power (MW) Imaginary Power (Mvar) Sending Receiving Losses Sending Receiving Stored BUS 1 BUS 2 102.714 100.650 2.064 56.653 49.773 6.88 BUS 1 BUS 3 1.379 1.378 0.001 0.4141) 0.4131) 0.001 BUS 3 BUS 2 101.378 99.350 2.028 56.990 50.227 6.763 Total Plosses = 4.093 Qstored in load = 13.644 1) Imaginary power flows from Bus 3 to Bus 1. The summation of real power losses and imaginary power storage over the transmission line are exactly same with total difference between generation and load. Therefore, it is verified that the difference is shown over the transmission line. Kirchoff balance as each bus [4] Bus1 ÃŽÂ £ P1 = + Pgen1 Pload1 P12 P13 = 204.093 100 102.714 1.379 = 0 ÃŽÂ £ Q1 = + Qgen1 Qload1 Q12 Q13 = 56.24 0 56.653 + 0.413 = 0 Bus2 ÃŽÂ £ P2 = + Pgen2 Pload2 P21 P23 = 0 200 + 100.65 + 99.35 = 0 ÃŽÂ £ Q2 = + Qgen2 Qload2 Q21 Q23 = 0 100 + 49.773 + 50.227 = 0 BUS3 ÃŽÂ £ P3 = + Pgen3 Pload3 P31 P32 = 200 100 + 1.378 101.378 = 0 ÃŽÂ £ Q3 = + Qgen3 Qload3 Q31 Q32 = 107.404 50 0.414 56.99 = 0 According to the calculation above, as summation of incoming outgoing real power and imaginary power at each bus become zero, it is verified that each busbar obeys a Kirchoff balance. In addition, the total power system is completely balanced, because total generation power (real imaginary) are equal to summation of total load demand and real power loss stored imaginary power over the transmission (i.e. Pgen Pdemand = Plosses, Qgen Qstored in load = Q stored in system) as shown above. Voltage Angle and Angle Difference As a result of the Powerworld, the voltage angle and angle difference are shown in the table below. BUS Voltage Angle Voltage Angle Difference BUS1 ÃŽÂ ´1 = 0.00 ° BUS1- BUS2 ÃŽÂ ´1 ÃŽÂ ´2 = 0.00 ° (-2.5662 °) = 2.5662 ° BUS2 ÃŽÂ ´2 = -2.5662 ° BUS2- BUS3 ÃŽÂ ´2 ÃŽÂ ´3 = -2.5662 ° (-0.043 °) = -2.5232 ° BUS3 ÃŽÂ ´3 = -0.043 ° BUS3- BUS1 ÃŽÂ ´3 ÃŽÂ ´1 = -0.043 ° 0.00 ° = -0.043 ° Power System Analysis -1 The table below summarizes generation and voltage angle variation at each bus as generation at Bus 3 varies from 0 MW to 450 MW by 50MW. Simulation Results and Observation P3 = 0 MW P3 = 50 MW P3 = 100 MW P3 = 150 MW P3 = 250 MW P3 = 300 MW P3 = 350 MW P3 = 400 MW P3 = 450 MW Reactive Power Generation at Bus 3: It is found that reactive power generation Q3(gen) decrease while real power generation P3(gen) increase because Bus 3 as a PV Bus regulates the constant bus voltage magnitude by controlling excitation of the generation through the AVR. Power Generation at Bus 1: It is found that P1(gen) decreases and Q1(gen) increases simultaneously, while P3(gen) increases and Q3(gen) decrease. As the total load demand in the system keeps constant (i.e. Ptotal(load) = 400 MW, Qtotal(load) = 150Mvar), any necessary real power and reactive power for the system balance need to be supplied by generator (slack generator) at Bus 1. Therefore, power generation P1(gen) and Q1(gen) at Bus 1 change reversely compared to power generation change at Bus 3. Voltage Angle Difference: In general, real power flow is influenced by voltage angle difference between sending bus and receiving bus according to PR =. Therefore, it is observed that as real power generation P3(gen) increases real power flow from Bus 3 to Bus2 increase, accordingly voltage angle difference (ÃŽÂ ´3 ÃŽÂ ´2) between Bus 3 and Bus 2 increases. However, decrease in real power from Bus 1 to Bus 2 due to increase of P3(gen) result in decrease of voltage angle difference (ÃŽÂ ´1 ÃŽÂ ´2). In addition, Real power between Bus 1 and Bus 3 flows from Bus 1 to Bus 3 until P3(gen) reach to 200 MW and as P3(gen) increase more than 200 MW the real power flows from Bus 3 to Bus 1. So, it is also observed that voltage angle difference (ÃŽÂ ´3 ÃŽÂ ´1) is negative angle when P3(gen) is less than 200MW and the difference increase while P3(gen) increase. Power System Analysis -2 The table below summarizes the variation of power generation and voltage angle difference at each bus when the load demand at Bus 3 varies by 50MW and 25Mvar. Simulation Results and Observation P2 = 0 MW Q2 = 0 MW P2 = 50 MW Q2 = 25 MW P2 = 100 MW Q2 = 50 MW P2 = 150 MW Q2 = 75 MW P2 = 250 MW Q2 = 125 MW P2 = 300 MW Q2 = 150 MW P2 = 350 MW Q2 = 175 MW P2 = 400 MW Q2 = 200 MW P2 = 450 MW Q2 = 225 MW Power Generation at Bus 1 and Bus 3: It is observed that as the total load demand in the system increases due to increase of load demand P2(load) Q2(load) at Bus 2, any necessary real power for the system balance is supplied by generator (slack generator) at Bus 1 considering constant P3(gen), so P1(gen) increases. In addition, any necessary reactive power for the system balance is supplied from Bus 1 as well as Bus 3, so both Q1(gen) and Q3(gen) increase. Voltage Angle Difference: It is found that real power flow increase both from Bus 1 to Bus 2 and from Bus 3 to Bus 2 due to increase of load demand at Bus2. Accordingly, both voltage angle difference ÃŽÂ ´1 ÃŽÂ ´2 and ÃŽÂ ´3 ÃŽÂ ´2 increase when the power flow P12 and P32 increase. In addition, when P2(load) is less than 200 MW, P1gen is relatively low. Therefore real power between Bus 3 and Bus 1 flows from Bus 3 to Bus 1 at lower P2(load) (less than 200MW). On the other hand, while P2(load) increase more than 200 MW, the real power flow direction changes (Bus 1 to Bus 3) and the real power flow increases. Accordingly, the voltage angle difference ÃŽÂ ´1 ÃŽÂ ´3 change from negative to positive and increase. Voltage Magnitude at Bus 2: It is observed that magnitude of bus voltage at Bus2 drops due to increase of the load demand at Bus 2. Question 2 System Model Admittance Matrix In order to construct the admittance matrix of Powerworld B3 case, single phase equivalent circuit can be drawn as below; z = r + jx (r = 0, x = 0.05) z12 = z21= j0.05 pu, y12 = 1/ z12 = 1/j0.05 = -j20 pu = y12 z13 = z31= j0.05 pu, y13 = 1/ z13 = 1/j0.05 = -j20 pu = y31 z23 = z32= j0.05 pu, y23 = 1/ z23 = 1/j0.05 = -j20 pu = y32 Admittance matrix can be defined as follows; BUS = Diagonal elements Y(i,i) of the admittance matrix, called as the self-admittance [lecture slide] [6], are the summation of all admittance connected with BUS i. = y12 + y13 = -j20 j20 = -j40 pu = y21 + y23 = -j20 j20 = -j40 pu = y31 + y32 = -j20 j20 = -j40 pu Off diagonal elements Y(i,j) of the admittance matrix, called as the mutual admittance [lecture slide] [6], are negative admittance between BUS i and BUS j. = y12 = -(-j20) = j20 pu = y13 = -(-j20) = j20 pu = y21 = -(-j20) = j20 pu = y23 = -(-j20) = j20 pu = y31 = -(-j20) = j20 pu = y32 = -(-j20) = j20 pu Therefore, the final admittance matrix BUS is; BUS = = The following figure shows the BUS of the Powerworld B3 case and it is verified that the calculated admittance matrix is consistent with the result of the Powerworld.

Physics of the Acoustic Guitar Essays -- physics guitars

Stringed instruments are most likely the oldest type of musical instruments. The acoustic guitar has been around since the 1500's, and is the most common stringed instrument used today. The guitar is one of the most versatile instruments in existence, being used in virtually every style of music. It can produce a wide range of sounds depending upon the style of the guitar and the type of strings used on it. The two main styles of acoustic guitars are the nylon-stringed and the steel-stringed. Nylon-stringed guitars are used mainly for styles such as classical music and flamenco. Steel-stringed guitars are most commonly associated with country and folk music. Before getting into how the guitar works, it will be beneficial to take a look at the different parts that make up a guitar. A guitar has three main parts- a body, neck and headstock. There are various styles and designs for acoustic guitars, but no matter the style, all of them have essentially the same parts. The body acts as an anchor for the neck and bridge. The top of the body is called the sounding board. It is responsible for almost all of the guitars acoustics, and is what allows the ear to hear the sound created by playing the guitar. The sounding board generally has a large hole cut in it called the sound hole. The bridge, which is also located on the sounding board, is what anchors the strings to the body. The neck is the long, slender part of the guitar connecting the body to the head. the front of the neck is called the fret board. This is where the frets are spaced down the entire neck. The frets are thin bars that are set perpendicular to the strings.

Marketing $100 Laptop

Mr. Negroponte wanted to create educational opportunities for the world’s poorest children by providing each child with a low cost laptop. This laptop will have educational software to provide children with otherwise unavailable technological learning opportunities. OLPC provides an interesting vantage point from which to examine the dynamics between non-profit and for-profit competitors because of the rapid development of the low-cost laptop market. OLPC was undoubtedly the innovator in this category of low-cost laptops with their â€Å"$100 laptop† concept. However, now that for-profit companies have entered the market and released a slew of similar products, OLPC must find ways to maintain its competitive advantage. OLPC was facing some marketing challenges and some the non-marketing challenges. The $100 price for the laptops is to be achieved by operating with no profit, cutting all unnecessary frills including marketing campaigns and assembling large quantities of computers. Negroponte estimated the program will launch with a distribution of at least 5 million computers, and said he hopes to increase that number to 100 million by the second year. He predicted that as the laptop design improves, the per-unit price will go down. Marketing Challenges: †¢ Marketing a low-cost, lightweight laptop seemed contradictory to recent products that are lightweight and ultra-thin that were typically more expensive and harder to manufacture. †¢ Most children using $100 laptop would not have ready access to electricity. †¢ Consumers criticizing OLPC for discounting the value of teacher training and curriculum development using the device. †¢ Governments opting out to put its resources toward traditional method of education. †¢ Prices for the OLPC don’t seem to stay at $100 causing different price floats. †¢ Competition like Intel(for profit companies) launching its own cheaper laptop targeting developing nations as well. Offering enhanced capabilities and the ability to run version of Linux or Window XP 3. Analysis: Differentiation: Price and Technology OLPC should differentiate its product, the XO, from direct competitors such as Intel’s Classmate PC and indirect competitors in the netbook category such as Dell Mini product lines. Differentiation must be visible on three distinct levels; price, technology, and brand. Price: OLPC is currently the cost-leader in this category. The Intel Classmate PC, which is OLPC’s most direct competitor, is currently priced at $285. The OLPC’s XO is priced at $175. Since both OLPC and its competitors are serving government education programs, cost will be extremely important as a number of nations are creating bidding wars for purchasing contracts. Even though OLPC is the lowest cost offering at this point, maintaining this price advantage will become increasingly difficult as competition in the market for low-cost laptops heats up. OLPC overcame some of the challenges by keeping laptop at low-cost by outsourcing the major design work and key part of the operating systems to different countries. Technology and Innovation: OLPC had a first-mover advantage in this market as its XO offering was perhaps the first entrant into the affordable netbook category. OLPC is specialized for its market of children ages 6-12. The design and child-friendly operating system is very unique. The unique connectivity is important for rural areas with sparse communications infrastructure. The XO is built for ultimate adaptability. Even its power sources can be diversified. OLPC has done an admirable job differentiating its product from its competitors through its innovative technologies and education-specific software and hardware. Competitive Strategy: Though OLPC is a leader on price and feature set, sustaining this advantage will be extremely difficult when facing competition from the largest computer companies in the world. Thus to keep its top position, it must leverage its advantages as a non-profit organization. OLPC must create value from its non-profit status to build reputation and trust. As a non-profit, OLPC can build goodwill in ways that for-profit companies are not able. Also being a non-profit enables OLPC to finance and maintain pricing schemes that are different than the competition. In terms of cost savings, OLPC has the advantage that many companies are eager to produce components for the OLPC. For example, Microsoft has gone out of its way to create a version of Windows to run on the OLPC. This is a cost savings that competitive firms are unable to match. To exploit this advantage further, OLPC could even attract advertisement agency to advertise on their PCs to further lower the cost of each machine.

3 Hot Industries to Watch in Donald Trump’s America

3 Hot Industries to Watch in Donald Trump’s America After the election, whether you’re happy with the outcome or not, one thing remains true: a new president means a new era. Changes in the economy tend to come as the new president takes office and starts enacting policies. And politics aside, there are some industries you should be keeping your eye on as America embarks on its Trump administration journey†¦ especially if you’re not selected for a cabinet position. ManufacturingDuring the campaign, Trump made a lot of promises about bringing manufacturing jobs back from overseas. Realistically, many of these jobs have been replaced by technology and automation- but this shift actually creates new opportunities in the manufacturing sector. While these jobs may have been blue collar, factory-floor jobs in the past, now the openings will more likely be in areas like industrial design, logistics (trucking and transit), marketing, and other front-office-type jobs. In decades past, a high school diploma was usually the ti cket to a solid manufacturing job, but as the industry undergoes further changes, you’ll see more opportunities for those with postsecondary education (training programs) or higher.Example:  Industrial DesignerThe job: Industrial designers develop concepts and plans for manufactured goods like cars, electronics, toys, etc. This is a role that combines engineering, creative design, and business needs to create products that are cost-effective to produce and useful to consumers.Education required: Bachelor’s degreeThe salary: Median salary of $67,130 per year, according to the U.S. Bureau of Labor Statistics.HealthcareWhether or not Obamacare is repealed and/or replaced under a Trump administration, healthcare is going to continue to be one of the career hotspots in the next four years, and a focus for economic growth.Example: Medical AssistantThe job: Medical assistants are professionals who handle administrative and clinical tasks in healthcare facilities like hospit als, clinics, doctor’s offices, or nursing homes.Education required: High school diploma, plus completion of a training programThe salary: Median salary of $30,590 per year, according to the U.S. Bureau of Labor Statistics.CybersecurityThis is a hot-button issue- perhaps you’ve heard? If you’ve been paying attention to the news, you’ve seen the same themes pop up over and over all year long: â€Å"hack,† â€Å"breach,† â€Å"leaked emails,† â€Å"Russia.† Personal data has become kind of like the Wild West out there- the info exists, therefore someone will claim it. Every industry and just about every company struggles with keeping ahead of hackers and would-be bad guys seeking to snipe others’ information for their own gain, and that will likely continue over the next few years as more and more public attention is brought to these security breaches.Example:  Information Security AnalystThe job: Information security an alysts are IT professionals who are often a company’s first line of data defense. They plan and implement security measures throughout a company’s computer networks and systems, to defend against cyberattacks and data breaches.Education required: Bachelor’s degreeThe salary: Median salary of $90,120 per year, according to the U.S. Bureau of Labor Statistics.As with any new president, the best thing you can do, career-wise, is to prepare for change: new technologies, new national priorities, and new policies. You never know where the opportunities will arise, so it’s important to be open to those changes, no matter how you feel about the politics of it all.

Human Resource Management in Competitive Environment Essay

Human Resource Management in Competitive Environment - Essay Example These areas account for the vast mainstream of academic work in the field. The paper concludes with our appraisal of how research should be built-up from this point forward. There is still important diversity in the literature over the implication of 'strategic human resource management' and its cohort term, 'human resource strategy'. It is vital that we take time to explain our terms, because the definitions we assume color the way we think about the key conjectural tribulations connected with the subject. To initiate with, what do we mean by 'human resource management' and by that old word 'strategic' Our inclination is for a broad, comprehensive definition of HRM. human resource management comprise anything and all connected with the management of service relationships in the firm. We do not connect human resource management exclusively with a high-commitment model of labor administration or with any exacting ideology or style of organization. High-commitment strategies do exist, but we are also apprehensive with the many cases in which management is following routine goals through lower levels of regard or is looking for to manage composite, segmented employees through variable levels of dedication (Boxall 2001; Purcell 2001, 1999a). To produce better theory and enable better practice, the academic regulation of human resource management should identify and evaluate the variety of organization styles that exist in modern workplaces. What dissimilarity does it make, then, when we apply the adjective strategic to HRM In many cases, together with a large number of manuals, it means nothing at all. If, though, we aim to be careful about words, the request of the adjective strategic must imply a concern with the ways in which human resource management is critical to organizational effectiveness. There are always strategic alternatives associated with labor progression in the firm -- whether highly considered or largely developing in management behavior -- and these choices are unavoidably associated to the firm's performance (Child 1972, 1997; Dyer 1984; Mintzberg 1978; Purcell and Ahlstrand 2003, 37-42). It is helpful to think of strategic choices on two levels: they either play a vital role in reinforcement the firm's viability (make-or-break choices) or them explanation for major, ongoing differentiation in business performance (Boxall and Steeneveld 1999). In adopting this sympathetic, it is suitable to refer to a firm's pattern of strategic choices in labor administration (including critical ends and means) as its 'human resource (HR) strategy' (Dyer 1984). To illustrate what we mean about strategic choices in HRM, take the case of a management consulting firm that aims to join the elite cluster of firms that are transnational, if not 'global' in their reach (firms such as McKinsey, PricewaterhouseCoopers and Anderson Consulting). There is no doubt that such a firm must have highly selective recruitment and strong development of staff to ensure it can consistently offer clients high-quality service on complex business problems.

The importance of human resource factore in labout process Essay

The importance of human resource factore in labout process - Essay Example Untrained individuals can only be considered just as "units of population" whereas trained and skilled individuals could justifiably be called as human resource. While the former is an asset to an organization, the latter invariably constitute the source of innumerable problems. Now the onus rests on the HR managers not only to select the right kind of candidates for various job openings but also to see that already working candidates also are continuously upgraded in their skills so that their contribution to the organizational growth is a continuous affair and not one which rests on chances. While there could be very many factors which influence different kinds of employees, still we could always lay our hands on a few principles which have at least widespread, if not universal, application potential. In this analysis we try to identify such valuable HRM principles which have proven their worth in many organizations under many conditions. Such an exercise would sharpen our insight into many valuable HR practices and equip us with the kind of expertise which would help us handle our manpower in the most efficient way so that the mutual benefit of both the employers and the employees are optimized. Considerable studies and research over the past few decades in the arena of HRM has enriched the subject itself with a variety of powerful principles culled from the past experience of various organizations in different world zones. Of the various HRM theories such as, Staffing Selectivity, Influence of Training on Firm Performance, Information Sharing, General Systems Theory, Role Behaviour Theory, Institutional Theory, Resource Dependence Theory, Human Capital Theory, Transformation Cost Economics, Agency Theory, The Resource Based Theory of the Firm, Compensation and Performance Management Systems, Job Security, Employee Participation Systems, Internal Labour Market Theory and Team-based Production Systems, let us take up for analysis and study some of them which are more relevant and/or powerful in delivering results in the present market scenario. a) Staffing Selectivity aspect : The success of every organization is measured by the quantum of business it is able to create and the amount of profit that comes out of it. To accomplish this every employee has to contribute his or her mite in no small way. Any weaker link in the corporate chain can easily undermine the strength of the entire organization and the downfall could be fatal. So it is imperative that Staffing Selectivity plays a crucial role in the success or failure of any organization. Hiring, firing and promotion should all be crucially selective. The right kind of employees should only be selected for every job
