HRM practices worlwide Essays

HRM practices worlwide Essays HRM practices worlwide Essay HRM practices worlwide Essay Building the National HR Competency Model: The four pillars of Professionalism By Marius Meyer, CEO: SA Board for People Practices (SABPP) Last month we introduced you to the new national HR Competency Model of the SA Board for People Practices (SABPP). As the HR standards-setting and professional body for HR, the aim of the model is to set a national standard for HR competence, and to provide HR professionals with a common framework for developing the required competencies in meeting the national standard. The model recognises that HR professionals are at different levels, specialisations and stages in their careers, et a common framework is intended to provide focus, consistency and development opportunities. SA Board for People Practices www. sabpp. co. za The competency model consists of three broad competence areas: 1 . The four pillars of professionalism form the square shape of the house as the foundation for professional HR practice. 2. Five core competencies needed by HR professionals to do high quality HR work constitute the building blocks. 3. Five HR capabilities required to ensure strategic HR impact form the roof. In this article we focus on the pillars of professionalism, i. e. duty to society, ethics, rofessionalism, as well as HR and Business knowledge. The central argument is that for HR to have an impact at the strategic and governance levels of organisations, we first need to get the basics right, not only to be regarded as true professionals, but also to develop our competence at the basic entry level where any profession gains stature and credibility, as the foundation of competence in any profession. PILLARS OF HR PROFESSIONALISM Drawing on the doctoral study by Penny Abbott at the University of Johannesburg, and masters dissertation of Huma van Rensburg at the University of Pretoria, but eworked as part of the new national HR competency model, the four pillars of HR professionalism form the foundation of the HR Competency Model: 2 Duty to society: Penny Abbott highlighted the socio-economic role of HR in society. HR professionals have a duty to society in delivering high quality HR work that has an impact on society. As professionals it is our duty to ensure that employers comply with labour and other relevant legislation and codes of good practice. We also need to be the custodians for good people practices in organisations, and ensure that people are treated fairly, and with respect and dignity. Furthermore, HR competence in driving effective transformation, skills development, sustainability and BBBEE interventions contributes significantly in fulfilling our duty to society. In addition, meeting or exceeding international labour standards such as the guidelines of the International Labor Organization epitomises our commitment and duty to society. On the negative side, but consistent with the standards and approaches used by other professional bodies, SABPP needs to ensure that registered HR professionals who do not meet professional and ethical standards are scrapped from the HR register of rofessionals. In this way, we fulfill our duty to society by protecting society (employees, employers and broader society) against unprofessional and unethical practitioners. Ethics: HR professionals should contribute to ethics in organisations and drive ethics in accordance with the SABPP Ethical Code and HR Guide on Ethics. Hence, competence in the area of ethics enables HR professionals to support management teams in meeting the ethical requirements of the King Ill Code on Governance for South Africa, as well as the requirements of the Companies Act. On he one hand, we need to behave ethically as HR professionals and meet our own national professional code of ethics irrespective of where we do HR work. On the other hand, HR professionals have to play a proactive role in driving ethics and values within their organisations in accordance with the espoused values and principles of their companies. Thus, HR professionals become champions of ethics, integrity and honesty in the workplace. The real test of HR competence in the area of ethics is whether we can challenge and influence management in creating an ethical alues-driven organisational culture. Professionalism: HR professionals should manage themselves professionally in acting and behaving like true professionals in the standard of HR work they deliver. Competence as a professional constitutes two areas of competency, i. e. etting the basics of professionalism right, and secondly to provide professional approaches to HR problems and issues in the workplace. The ability to analyse problems in a professional and systematic way, and to deliver professionalism is all about. The basics of professionalism are to get the few ssential professional work skills right, for example doing your homework about an issue, preparing a high quality professional report or presentation, and providing appropriate feedback and measurements abou t the solutions implemented. HR and Business knowledge: HR professionals must have good HR and sound business knowledge if they want to be successful as professionals and strategic partners. HR professionals need sound HR knowledge of all aspects of HR, from HR planning and recruitment, right through to exit strategies. While functional experts such as organisation development or remuneration specialists require in-depth nowledge of their specialist areas, all HR generalists need to have sound knowledge of all HR functions in order to deliver integrated HR solutions. In 3 addition to HR knowledge, HR professionals must possess business knowledge to ensure alignment between HR work and the needs of the business. Therefore, the importance of sound business acumen to enable and compliment the execution of professional HR work can not be over-emphasised. CONCLUSION The new SABPP HR Competency model sets the benchmark for HR professionalism in the modern South African work environment. Considering the four pillars outlined in this article, one could say that our duty to society forms the foundation of the HR competency house. In essence, our duty to society compels us to answer the question: What difference do we make as HR professionals to our organisations and the society in which we operate? Ethics and professionalism are the walls. If the foundation and walls are not strong, the house will fall down. Furthermore, HR and business knowledge is the ceiling of the house, thus acquiring sound HR and business knowledge opens up opportunities for HR professionals to move to the trategic level of the HR house, i. e. the roof. Ultimately, all professions are guided by similar pillars, although the context differs from profession to profession. Building the HR profession on a strong foundation and grounded in the four pillars, HR professional competence does not only resolve around the need for getting its own house in order, it also positions HR at a comparable level of competence to other professions. However, our credibility as HR professionals will depend on our ability to continuously develop our competence in the four pillars of the HR profession in order o raise to the level of excellence expected from our stakeholders.

Ishmael Essay Example | Topics and Well Written Essays - 1250 words - 1

Ishmael - Essay Example The idea is to have the government forces the citizens into the idea of having no personal property until they are used to it, then the government can dissolve. The problem that Ishmael is discussing is that people are trying to fix a system within a prison, but no matter what, being in that prison will prevent any perfection of any system. This system that is being referred to is society. What is basically being argued throughout the book is that it does not matter how hard people attempt to fix the system, it will inevitably fail because it is still within the prison. More aptly put, society is the prison and the system at the same time that we are trying to fix. There are various reasons that we will be unable to fix society. The book defines two concepts which are important to understand why society cannot be fixed. The first is Takers, which refers to people of the heritage from the agricultural revolution. The second is Leavers, which refers to people who those of other non-Taker cultures, which might be referred to as primitive. The character Ishmael states that it is because Takers view themselves as being responsible and in charge of other species. Because Takers are not perfect, omnipotent beings, there is no way for them to be able to discern what should actually be done in regards to other species. This is basically why our society will not work, and the view put forward by the book is that society will continue to be ineffective to the point that it will wipe out the Takers, the very thing that it was supposed to have been set up to save in the first place. This is ultimately what the quote means. To mention communism again, state-mandated redistribution of wealth is not going to work, according to Ishmael. It is simply an attempt to construct the system in such a way as to perfect the system, but of course as

Child Care Care for Babies Essay Example | Topics and Well Written Essays - 500 words

Child Care Care for Babies - Essay Example They are not comfortable with the idea of two caregivers having to attend a minimum of ten babies at the same time. Thinking of the direct relationship between the baby's mood swings and a caregiver's mood swings makes them forecast possibility of a caregiver's outburst of frustrations and inability to fulfill task. The scene just can't be concluded yet if all of the ten babies will cry at the same time. The couple needs to work and they are only able to do that when they are secure in their knowledge that their children are safe and in good hands. It will be unwise or unfair to expect a clone of the parent. However we can respond to the worries by convincing them that the caregiver is a decent and kind individual. To give them a good outlook of the care the center is providing they will be given an opportunity to interview the caregivers at a preset time to satisfy their parent's instincts. In this way the parents will be able to personally describe the routines of the baby and caring schemes for their child apart from what was listed in the enrolment form. The act will give them comfort that they have personally clarified in detail the baby's management and care in question.

Two Weeks Notice Essay Example for Free

Two Weeks Notice Essay Two weeks notice Bullock plays Lucy Kelson, a committed left-wing attorney with an immaculate Ivy League background who fights the good fight against the heartless developers of lower Manhattan and the outer boroughs. Complications ensue when she finds herself working for one such figure, George Wade (Grant) in exchange for his preserving a Coney Island landmark near her childhood home. Wades not a bad guy, but hes frightfully dependent on Lucy for everything. When it seems possible she might at last get clear of him, she begins to have second thoughts about letting him go. The Movie Two Weeks Notice stares Saundra Bullock and Hugh Grant premiered in December of 2002. The movie follows a mix match relationship between a strong willed, save the community lawyer named Lucy Kelson, played by Sandra Bullock, and a high status business man, George Wade, played by Hugh Grant. The two in the beginning seem completely different but when Lucy goes to work for George, to keep him from knocking down the neighborhood community center, she realizes how needy he was, and how much she couldnt stand it. When Lucy gives George two weeks notice, George realizes that she is an asset to his company. After much arguing she finally gets out and then they both realize that theyve fallen in love with each other. Since they were too stubborn to admit it, it took a huge argument in the employee lounge to get them to let their guards down. Writer and first time Director, Marc Lawrences Two Weeks Notice is a charming, smart, and genuinely funny romantic comedy with terrific performances by Sandra Bullock and Hugh Grant. This a great movie. Inherent in romantic comedies is a degree of predictibility. Two Weeks Notice follows formula, but Lawrence orchestrates enough curves, character insight, and human resonance to make it more than just formula. He also has the great chemistry of Bullock and Grant this is their medium. Sandra Bullock plays Lucy Kelson, a Harvard educated activist lawyer, who is hired by George Wade (Hugh Grant)a handsome, charming, and seemingly shallow multi-millionaire develo per. George hires Lucy as chief legal counsel for Wade Corp. , for $250 K, because his brother Howard (David Haig), the true captain of Wade Corp. requested George hire an attorney who did not attend Bimbo U. Lucy swallows her idealism and poverty, because George also promises to protect her parents community center. Lucy is smart and not intentionally funny, and soon becomes Georges right and left arm he cant to anything without her consult. This only amplifies that Lucy has no life or rather any relationships of merit other than with George. Lucy gives George her Two Weeks Notice. Credit Lawrence and company, when George finally accepts Lucys resignation, it is crystal regarding the unspoken relationship of the two. Wink. Wink. Two Weeks never insults our intelligence, however, it makes us await for an hour and a half. Along with wit and humor Lawrence, Bullock, and Grant provide a a very human touch that resonates throughout the movie. In a very well done scene on the rooftop of Lucys parents New York apartment, Lucy shares with George that she never lived upto her mothers expectations. George says that is different from people having no expectations. This is where movie transforms beyond the opposites attract story. It makes sense of Lucys need to be perfect, and the man that George could be that he is well aware of. In its own light hearted way, Two Weeks looks at where you sell out, where do you become a whore (but in a nice way), and where do you take a stand. And taking a stand is never easy even in a romantic comedy, though it sometimes takes longer. Sandra Bullock and Hugh Grant are magic together. They are both smart and their characters are also. Grant as George is charming, witty, and playing someone who has honor and substance that are dimissed by all except Lucy (Bullock). Grant is masterful at hinting at a depth of character. Sandra Bullock is beautiful, smart, and funny as Lucy. She also stretches herself when Lucy drunkenly braggs about her sexual prowess bobcat pretsel thing. Bullock lends compassion and a whacky sensibilty to Lucy who scares men off by being too smart and too perfect, but still not good enough for her mother. Her Lucy only gets a clue when she hires her replacement (a good Alicia Witt) she is in love with George. The exchanges between Grant and Bullock are so natural like conversation, spoken and unspoken. At one point in the movie, Lucy has a breakfast conversation with her Dad (a goofy and wise Robert Klein). She asks him What if people dont change? The point is they will or they dont. Kind of like loving someone is accepting them for who they are and for who they are not. Be open to surprises. Marc Lawrences Two Weeks Notice is an excellent surprise. He along with Bullock and Grant have made a classic romantic comedy and more. Hugh Grant plays George Wade, a property developer who hires Lucy Kelson (Sandra Bullock) as his Chief Counsel. Sick of calls in the middle of the night and appalled at being called away from a wedding just to help her boss decide what to wear for a particular occasion, Lucy gives George two weeks notice. ‘Two Weeks Notice is little more than a predictable romantic comedy and it is only a matter of time before George and Lucy realise that they have fallen for each other. How the film turns out is obvious, but this will not spoil your enjoyment of it. Sandra Bullock fails to convince as a successful lawyer and businesswoman but she is able to convey a vulnerability which makes the audience warm to her. Like her character in ‘While You Were Sleeping, Lucy is a lonely individual. When she is at home she comfort eats Chinese food, always ordering just for one. There are also no surprises with Hugh Grants character as he is much the same as any of his other romantic roles i. e. very likeable and charming. The film succeeds purely because of the actors likeability and the on-screen chemistry between Hugh Grant and Sandra Bullock who are both gifted comedic actors. There are also enough good lines and funny situations to keep you chuckling throughout

Small Business, Non-profit Organizations, and E-commerce :: Exploratory Essays Research Papers

Small Business, Non-profit Organizations, and E-commerce Small business firms and non-profit organizations can seize the opportunities that the Internet offers. The number of Internet users worldwide exceeded 150 million in 1999, and this number is expected to quadruple in a few years. These users are a vast market for organizations offering products or services on web sites. Firms such as Amazon.com and eBay have exploited this market, growing from nothing to giants in less than a decade. Naturally, many small firms want to get in on the action by establishing their own web sites. Other organizations, such as professional associations, want to use web sites to recruit members and create an Internet presence enhancing both their members' reputation and marketability. What is the best way for them to proceed? A boutique might be very competent at acquiring clothes that float off the rack. Each professional member of a not-for-profit association might co-ordinate the activities of hundreds of people. However, designing, constructing, maintai ning, and managing an Internet site requires technical expertise and capital these organizations don't necessarily have. Can the government assist by providing information and financing to organizations wanting to enter cyberspace (Canada, Western Economic Diversification)? To compete with the big players on the Internet, small businesses and non-profits, with help from the government, can contract with experienced web-consulting firms to supply the programming and computer skills to ensure delivery of a web site for a reasonable price. Although primarily an economic phenomenon, electronic commerce forms part of a broader process of social change, characterized by the globalisation of markets, the shift towards an economy based on knowledge and information, and the growing prominence of all forms of technology in everyday life (OECD Economic 143). The Internet has hastened the globalization of markets. A few decades ago, only the multi-national corporations sold products worldwide. "Today, for a few thousand dollars, anyone can become a merchant and reach millions of consumers world-wide" (OECD Economic 10). Unfortunately, Canadian small businesses are not embracing e-commerce as ardently as American firms. Many domestic firms have neither the investment capital nor the technical knowledge to seize the opportunities the Internet offers. Consequently, Canadian firms lag behind American firms. While the American economy is ten times larger than Canada's, American venture capital investment in the Internet was 36 times larger last year ("E-business Acceleration"). Although the Canadian government is making an effort to encourage e-commerce (Canada, Industry Canada, The Canadian Electronic), some firms paid exorbitant prices for e-commerce sites that are not profitable because they lacked accurate information on the cost of constr ucting web sites.

Data compression techniques apply various principles to reduce the size of data. One, called _______________________, avoids repeating long strings of the same data item. Another, called _____________ __________, encodes the difference between consecutive blocks of data rather than encoding each block in its entirety. Still another, called _________________________, uses short bit patterns to encode frequently occurring items and longer patterns to encode less frequent items.ANSWER: Run-length encoding, relative encoding, and frequency-dependent encoding. Vocabulary (Matching) Questions The following is a list of terms from the chapter along with descriptive phrases that can be used to produce questions (depending on the topics covered in your course) in which the students are ask to match phrases and terms. An example would be a question of the form, â€Å"In the blank next to each phrase, write the term from the following list that is best described by the phrase. † TermDescriptive Phrase bitBinary digit Boolean operationAND, OR, XOR, NOT addressA numeric value used to identify a memory cell exadecimal notationAn efficient way of representing bit patterns sectorA segment of a track in a mass storage system zoned-bit recordingA means of increasing the storage capacity of a magnetic disk system bufferA storage area used to hold data on a temporary basis, often as a step in transferring the data from one device to another ISOAn international organization for establishing standards ANSIA major standardization organization within the United States ASCIIA system developed by the American Standards Institute for encoding text. lip-flopA digital circuit capable of holding a single digit two’s complement notationA means of encoding whole numbers floating-point notationA means of encoding numeric values that may involve fractions truncationAn error that may occur when using floating-point notation pixelA small part of an image GIFA means of compressing an image file by restricting the number of colors availableJPEGA means of compressing images by blurring the boundaries between different colors while maintaining all brightness information UnicodeA mea ns of encoding text in which each symbol is represented by 16 bits LZWAn example of adaptive dictionary encoding MIDIA means of encoding music in terms of notes and instruments rather than actual audio Key fieldA part of a logical record in a file used to identify the record. VLSIA means of constructing complex circuitry in a very small space.General Format Questions 1. Describe how a computer can produce an incorrect answer when performing numerical computations even though it has not malfunctioned. ANSWER: Most students will probably refer to overflow and truncation errors. 2. Describe ho the concept of Hamming distance is used to produce an error-correcting code. ANSWER: By designing a code in which each pattern has a Hamming distance of n from any other pattern, patterns with fewer than n/2 errors can be corrected by replacing them with the code pattern that is closest. . a. What is the output of the circuit below? [pic] b. In general, how does the three-bit input pattern across the top of the diagram relate to the circuit’s output? ANSWER: a. 0 b. The output is 0 if the input parity is odd; the output is 1 if the input parity is even. 4. If the input and output bit patterns in the circuit below are interpreted as binary representations of numeric values, what operation does the circuit perform? [pic] ANSWER: The circuit subtracts one (except for the case of the input being 000). . Explain why such terms as kilobyte, megabyte, and gigabyte have acquired double meanings. ANSWER: The prefixes kilo, mega, and giga are used traditionally to refer to units measured in powers of ten. However, due to the early misuse of the prefix kilo in reference to units of the size 1024, these prefixes are now often used to refer to units that are powers of two—especially when referring to the capacity of main memories. 6. Convert the following addition problem into two’s complement notation using four bits per value), perform the addition, convert the an swer back into base ten notation, and explain the results. 6 + 3 ANSWER: In two’s complement notation the problem is to add 0110 and 0011. The sum is 1001 which translates to -7. This answer is incorrect due to overflow. 7. Under what condition is each of the following data compression techniques most effective? a. Run-length encoding b. Relative encoding ANSWER: a. Compresses most when data consists of long strings of the same entry. b.Compresses most when each block of data differs little from the previous block. 8. What is frequency-dependent encoding? ANSWER: Frequency-dependent encoding is an encoding system that uses short bit patterns to represent data items that occur most often and longer patterns to represent less frequently occurring items. The result is that entire blocks of data can be represented in less space than would be required if each data item were represented by the same size bit pattern. 9. Construct the entire two’s complement scale in which eac h value is represented by three bits.ANSWER: 3 011 2 010 1 001 0 000 -1 111 -2 110 -3 101 -4 100 10. To what does the term â€Å"normalized form† refer in the context of floating-point notation? ANSWER: Normalized form refers to a standard for positioning the bit pattern within the mantissa field. Many values can be represented in floating-point notation by different bit patterns, only one of which is in normalized form. Hence, restricting representations to normalized form assures that each value is represented by a unique pattern. 11.Explain why the final version of the dictionary need not be transmitted with a message encoded using LZW compression. ANSWER: The dictionary can be constructed during decompression in the same way it was constructed during compression. 12.
