Security Essentials 1.5 - Essay Example Contemporary society confronts security experts with distinct and frequently unprecedented security-associated concerns. The security sector was known as a growth sector even before 9/11 (Clifford, 2003). Affairs between civic law implementation agencies and private security experts in more recent years have been limited, even though it is purportedly transforming. History is full of cases where security purposes have been accomplished through the application of innovative minds, resourceful plans, and easily accessible solutions. Sectors evolve to meet these new social demands as society itself evolves. Exploration of artifacts offers evidence that shows attempts by the earliest communities to secure themselves from internal and external dangers. Particular communities discovered methods that were more dignified in an effort to assure security protection by building tools, starting agriculture, and settling in the long-term. These communities resided in regions with certain climates that presented particular security dangers as well as defenses (Clifford). Kangaroo justice was still a preferred option even after the establishment of formalized legislation in educated nations such as the United States. Historians commonly agree that tribal leaders or household members who represented the rest of the family determined security aims during eras that preceded recorded history and areas where legislations could not be implemented freely like the American Frontier. Archeological proof imply that civilizations dating as far back as five millennia BC designed and implemented laws to identify proper behavior. Ancient recorded attempts to build a series of criteria has been credited to the Sumerians as far back as five millennia BC. The Code of Hammurabi, 1750 BCE, is the later legal cannon that adopted Sumerian cannons, set up by King Hammurabi, and discovered in 1901. Draco’s Law applied to Athens in 621 BC and included punishments for numerous crimes that

Education System in the Philiphines Essay -- Education

The Philippines has a recent overflowing issue on its education system, which is the implementation of K+12 education system as the basic education curriculum (BEC). This issue is one of the most controversial things that Aquino Administration proposes. First of all, K+12 is an education system that includes Kindergarten with twelve years of elementary and secondary education (Department of Education, 2010). The Kindergarten is basically started at the age of 5 and the elementary education (primary education) holds for 6 or 7 years of education while secondary education, which holds for 5 or 6 years of education, is defined as high school (Department of Education, 2010). In comparison to the current 10-year education system, the K+12 system adds two extra years of education. According to the Department of Education of the Philippines (DepEd), their main purpose is not just adding two extra years of education rather to enhance the BEC in the Philippines (Department of Education, 2010). Discussions over the K+12 program have already been on since the Commonwealth era. The Americans has suggested this system to be implemented but President Manuel L. Quezon has set aside the issue to deal with more important problems in the country at that time (Vargas, 2012). Throughout the years after the Commonwealth era, suggestions have been made by foreign organizations (Department of Education, 2010). Then, a survey made by Presidential Commission to Survey Philippine Education in 1970 has recommended the government to give a high importance in implementing the 11-year program with 6 years of elementary education and 5 years of secondary education; but it never pushes through (Department of Education, 2010). The current 10-year program has n... ...s literacy rate and its quality of education system but also it would lessen the number of unemployment and underemployment in the country.

Career Transition

Career Transition In this paper, I will research career transition and how it has impacted the workforce and management. I will present from three research articles that I feel are important in understanding how career transition affects adults who are transitioning from one career to another. As an HRM, one of the biggest parts of our job will be to recruit new talent. Traditional careers are falling to the wayside and emerging is a type of employee who has been around the block once or twice. I am going to focus on first the way careers are changing, then I am going to look at the military and how they prepare their retirees, many of whom are still in their 30’s, for retirement, and finally, I will look at career transition and what role HR plays. Gone are the days of staying with one company until you are eligible for the pension and a gold watch. The average person born in the later years of the baby boom held 10. 8 jobs from age 18 to age 42, according to the Bureau of Labor Statistics of the U. S. Department of Labor (Number of Jobs Held, Labor Market Activity, and Earnings Growth Among the Youngest Baby Boomers: Results From a Longitudinal Survey Summary , 2008). Career transition is no longer looked at as something to avoid putting on your resume. It seems like everyone it doing. So how can a person make the transition smooth and successful? Career transition often requires employing new tools, skills and/or a switch in perception. In her article, Beyond the Career Mystique: â€Å"Time in,† â€Å"Time out,† and â€Å"Second Acts†, Phyllis Moen. states that Americans confront a major mismatch between outdated career and retirement regimes and the exigencies of (1) family responsibilities, and (2) the risks and uncertainties associated with a competitive, global, and information-based economy. Unlike privileged workers in the 1950s, members of America's 21st-century workforce find it increasingly rare to have either a full-time homemaker or a secure, â€Å"lifetime† job. This mismatch challenges both scholars and policy makers to revisit, research, and rewrite the disparate scripts constituting the rules of the career game. The mid-20th-century bargain of trading a lifetime of paid work for a lifetime of income security-never a reality except for a group of middle-class office workers and unionized production workers in the post war economic boom of the 1950s-is probably gone forever. (Moen) Her points regarding the changing career climate are spot on. Many of he lifetime jobs are ones that have no real advancement potential. A GS (Government Service) job will allow for increases in pay due to step promotion and COLA increases, but in order to advance into a higher GS position a person would have to make significant gains in their education and/or work experience. Both of these might require leaving the current job for a time period. In some cases, the GS jobs have no advancement potential even with additional education, a person would have to quit t heir current job and reapply for a new position. Even more evidence that points to employers changing the career game is an article published by the Bureau of Labor Statistics that states that employ ¬ers are replacing defined-benefit retirement plans with defined-contribution retirement plans, allowing employers to shift more responsibility for retire ¬ment income to the employee. (U. S. Bureau of Labor Statistics, 2010) So what are the consequences of this alteration of the career landscape? The median age of workers are increasing. The prime age group, composed of 25- to 54-year-olds, is projected to increase by 1. million and make up 63. 5 percent of the total labor force in the target year. The youth labor force, composed of 16- to 24-year-olds, is expected to decline from the 2008 level, but will remain over 21 million in 2018. The military is one area that has a great deal of experience with career change. Not only do the military members change jobs frequently, most retire after only 20 years of service. This puts someo ne who may only be 38 in the position finding new employment at a relatively young age. A study examined the concerns of retiring Marine Corps noncommissioned officers (NCOs) as they experience the adult career transition of retirement from military service and transition to the civilian workplace. Analysis of focus group transcripts reveal a range of concerns related to the transition factors cited in Schlossberg’s Transition Theory as the 4 S’s: situation, self, support, strategy. The study provided insight on the issues and challenges Marine Corps noncommissioned officers (NCOs), and all Military Personnel face upon retirement based on the following articulated themes: cultural, community, social and psychological concerns. The paper suggested that programming be offered to facilitate transition and should also address psychological and social concerns which may improve the quality and outcomes of transition to a new role in civilian life. (Johnston, Fletcher, Ginn, & Stein) Many of these jobs are in the skilled labor fields which are light on EAP's to assist once the transition has occurred. Next to the military, education is another area that see its fair share of transition. A quick Google search on career transition will bring up a plethora of sites offering advice on starting a second career in teaching. The main areas that see an influx are secondary high school education teachers and entry-level college instructors. Why are these areas so appealing? One paper seeks to reviews the current theory in areas relevant to industry-to-academia career transitions, and to outline a theory that targets this category of employee directly. They sought to outline the first step toward a limited theory explaining the special needs and motivations of industry-to-academia career transitions. Throughout this paper, the hybrid academic institution, consisting of a traditional core and a nontraditional periphery, received special emphasis. While the research did not conclusively define the reasons behind the transition, consider the following concepts: (1) proteanism, or the protean approach to career transitions; (2) transition types; and (3) human values. (Bandow, Minsky, & Steven) All of which are indicative not only in instances of industry-to-academia career transitions, but in most all other areas as well. Even for the most experienced and well-educated person, transition does require some finesse. Here are a few tips that can help make the change less traumatic. It is important to take a serious look at the many possibilities and outcomes before you jump into a new career or field. Consider these 10 tips as you make a transition from your present career to your next: 1. Have a clear plan. The smartest move that you can make is to carefully map out an effective career-change strategy. This should include a detailed action plan that takes into consideration finances, research, education, and training. Keep in mind that a successful career change can take several months or longer to accomplish, so patience is key. . Wait for the right time. The best time to consider a new career is when you are safely ensconced in your existing position. It is understood that a steady paycheck can relieve a lot of pressure. There are many ways to take steps toward your new career path; you can volunteer or offer yourself as a freelancer or consultant. This can help you to â€Å"test the waters† in your desired new field. 3. Be sure of your reasons. Just because you’re unhappy in your current job isn’t a strong enough reason to make a total career break. Carefully analyze whether it is your actual career you dislike or whether your employer, supervisor, or office situation is the problem. 4. Do your research. Be sure to examine all possibilities before attempting a career jump. Talk to people in your network; read career and job profiles; meet with a career management professional. The more information with which you arm yourself beforehand, the more successful you will be. 5. Decide what is important. This is the best time for thoughtful self-reflection. Ask yourself what it is you really want to do with the rest of your life. Take an honest inventory of your likes and dislikes, and evaluate your skills, values, and personal interests. Many people who are looking to change careers do so to find a balance between their personal and professional lives, to accomplish the right mix of meaning and money. You may want to consider consulting a career coach and/or taking a career assessment test. 6. Examine your qualifications. Do you have the necessary experience and education to be considered a qualified candidate in your desired career field? If not, you need to find a way to bridge the credentials gap. This might mean making your goal more long-term while you go back to school or receive additional training. 7. Learn about the industry. Get a feel for the field that interests you. Read industry journals, attend conferences, and talk to people in the profession about what they do. Learn whether your target industry has growth potential. Trade magazines, organizations, and entrepreneurs have created a slew of Web sites that offer searchable databases where job openings in many specific industries are listed. Start looking at these sites on a regular basis. 8. Develop your network. Begin nurturing professional friendships early and tend them regularly. Professional organizations and job industry trade associations are a good place to start. Many of them hold networking events and job fairs. 9. Update your job search skills. It is especially important to polish up your job-hunting skills and techniques before you get out there and start networking. Make sure you are using your time and resources as effectively as possible. 10. Pay your dues. Do not expect to begin at the same level of seniority in your new career that you held in your old one. It will take time to move up the ranks, but if you find a new career that you absolutely love, it will be worth it. (Ten Tips on Making a Successful Career Change) In conclusion, with the continued changing landscape of today's business world, career change is here to stay. People are having to work further into what used to be the retirement years and some are deciding to live to work instead of work to live. Whatever the reason the challenges of a career transition can be frustrating and rewarding at the same time. The most important thing is to be true to you and to not be afraid of new horizons.

Essay about functions assignment

Functions Assignment Question 1. A function assigns a unique output value to every input value. This definition implies that a vertical line cannot intersect a function in more than one place (Stewart). The set of input values is known as the domain of a function. The set of output values is known as the range of a function. An example of a linear function is, f left (x right ) = 4x+3 where 4 and 3 are the slope and vertical intercept of the straight line f(x). The domain of this linear function is all values x can take on, namely, all real numbers. The range is also all real numbers. A parabola is a good example of a quadratic function, f left (x right ) = {x} ^ {2} The vertex of the parabola coincides with the origin of a Cartesian coordinate system. The domain of this function is all real numbers and its range is all positive real numbers, f(x)≠¥0. An example of a third degree polynomial is, f left (x right ) = {x} ^ {3} +3 {x} ^ {2} +2x+1 The domain and range of this polynomial are all positive real numbers. The exponential function is defined as, f left (x right ) = {e} ^ {x} The domain of the exponential function is all real numbers and its range corresponds to all positive real numbers. The natural logarithm is a good example of a logarithmic function and is defined as, f left (x right ) = ln {x} The domain of the natural logarithm is all positive real numbers, x0. The range is all real numbers. The trigonometric functions are good examples of periodic functions. For instance, the sine function, f left (x right ) = sin {x} It repeats every 2Ï€ radians. The domain of the sine function is all real numbers. The range is -1 ≠¤ f(x) ≠¤ 1. Question 2. The electrical activity of the human heart can be monitored by means of an Electrocardiogram (ECG). An example of ECG signal is shown in Figure 1. The signal was retrieved from National Instruments website (â€Å"National Instruments: Test, Measurement, and Embedded Systems†). The electrical heartbeats are represented by the voltage amplitude (dependent variable) over time (independent variable). The figure shows that heartbeats exhibit nearly periodic behavior. Strong beats repeat approximately every 1.6 seconds. Figure 1. Example of hearts electrical activity. Question 3. The displacement of a piston in an internal combustion engine is represented by a periodic function, f left (t right ) = A sin {ωt} where ω is referred to as the angular frequency and has units of radians per second (rad/s). The independent variable is time t (s). A stands for the amplitude and describes the magnitude of the maximum displacement of the piston. The amplitude is a constant value. One cycle takes place when the crack (a linkage connecting the engine shaft and piston) turns through 2Ï€ radians. In other words, the sine function repeats itself when ωT=2Ï€, where T is the period, so this time is defined as, T= {2Ï€} over {ω} The frequency is the inverse of the period and it is measured in s-1 or hertz (hz) f= {1} over {T} For example, a period of 10s means a frequency of 1 every 10 seconds. The average value of function f(x) over an interval [a,b,] is defined as, F = {1} over {b-a} int from {a} to {b} {f(x)dx} The above expression can be used to calculate the average displacement over one cycle of the piston [0,T], F = {1} over {T} int from {0} to {T} {A sin {{2Ï€t} over {T}} dt=} {1} over {T} {left [- {T} over {2Ï€} cos {{2Ï€t} over {T}} right ]} rsub {0} rsup {T} =- {1} over {2Ï€} left [cos {2Ï€} cos {0} right ] =0 Question 4. The inverse of a function ( f -1) takes on a value from the range of f and assigns a single value from its domain. The inverse of a function exist only if a horizontal line does not intersect the function f in more than one place. This is not satisfied for the case of periodic functions like the sinusoidal displacement of a piston, y=f left (t right ) = A sin {ωt} The domain of sin ωt has to be restricted in order to define the inverse function. It can be worked out as follows, {sin} ^ {-1} {left ({y} over {A} right ) =ωt} {{f} ^ {-1} (y) = t = {1} over {ω} sin} ^ {-1} {left ({y} over {A} right )} The inverse function holds as long as, {Ï€} over {2} ≠¤ {y} over {A} ≠¤ {Ï€} over {2} In a given cycle of the piston, the inverse function provides the time for which the piston is displaced y length units. Question 5. Part 1. The Richter scale is a scientific tool to measure the intensity of an earthquake (â€Å"Khan Academy | Khan Academy†). The following facts summarize the main features of the Richter scale: The Richter scale measures the earthquake magnitude. The intensity or amplitude of the ground motion is collected at the measuring stations. The maximum ground motion detected at a measuring station can be plotted against the distance to the epicenter. The Moment Magnitude Scale (MMS) was calibrated to the Richter scale. MMS is related to the energy released by earthquakes. Unfortunately, strong and weak earthquakes do not fit on the same plot if a linear scale is used. The Richter scale employs a logarithmic scale in order to present the data on the same chart. The Richter scale can be used to compare the magnitude of two earthquakes. For instance, the 5.8 earthquake that took place on the east coast of US in 2011and the 9.0 earthquake off the coast of Japan in the same year. Both magnitudes are reported on a logarithmic scale so the difference between these two earthquakes is not 3.2 but 103.2 (3.2 powers of 10). It means the earthquake in Japan was about 1600 times stronger than the east coast earthquake. Part 2. Table 1 summarizes the facts about the earthquakes chosen to draw a comparison. Date Location of epicenter Richter magnitude scale (M) 25 September 2013 Southwestern Pakistan 7.7 27 February 2010 Central Chile (near city of Concepcià ³n) 8.8 Table 1. Earthquake information. Part 3. Quantitative comparison of the two earthquakes. The equation for Richter magnitude can be written as, M = {log} rsub {10} {A} where A is the amplitude in millimeters directly measured from a seismograph. The equation may also include a distance correction factor originally used by Richter. It is omitted for the sake of clarity. The Richter magnitude of Pakistans 2013 earthquake can be related to its amplitude by, 7.7 = {log} rsub {10} {{A} rsub {Pakistan}} The equation above can be written as an exponential equation, that is, the amplitude read in the seismograph, {A} rsub {Pakista n} = {10} ^ {7.7} Similarly, the magnitude of Chiles 2010 earthquake can be mathematically written as, 8.8 = {log} rsub {10} {{A} rsub {Chile}} It can also be recast as an exponential equation, {A} rsub {Chile} = {10} ^ {8.8} The ratio of exponential expressions can be used to compare the intensities of earthquakes, {{A} rsub {Chile}} over {{A} rsub {Pakistan}} = {{10} ^ {8.8}} over {{10} ^ {7.7}} =12.6 It can be concluded that Chiles earthquake was 12.6 times as intense as the recently ground motion in Pakistan. Task 1. The exponential function ex can be written as an infinite Taylor series about x=0. The Taylor series is, {e} ^ {x} =1+x+ {{x} ^ {2}} over {2!} + {{x} ^ {3}} over {3!} + {{x} ^ {4}} over {4!} +†¦ {{x} ^ {n}} over {n!} +†¦ It can be used to approximate the value of e1 up to n= 10. The results are shown in Table 2. The approximation value for e1 up to 10 decimal places is obtained when n = 15, e = 2.7182818285 n Approximation for e 1 1 2 2 3 2.5 4 2.666666667 5 2.708333333 6 2.7166666667 7 2.7180555556 8 2.7182539683 9 2.7182787698 10 2.7182815256 Table 2.
