Cuban American education

A Cuban American is a United States citizen who traces his ancestry to Cuba. Many communities in the United States have many people from the Cuba American community. This cultural diversity has brought numerous debates on the nature of education to be offered on these citizens. Most of the Cuban immigrants settled in the St. Augustine, Florida. After the united states claimed Florida from Spain, most of the Cubans were mainstreamed into the American culture. The Cuban revolution led by Fidel Castro necessitated the increase in the number of the immigrants to the US.These immigrants were of different education backgrounds and different professions. Source:http://usinfo. state. gov/scv/history_geography_and_population/population_and_diversity/hispanic_americans. html Cuban American students have for long been considered at risk in the American educational system. A better understanding of the diverse cultural experiences can help to counteract this risk. This understanding, this paper enhances development of the students towards being responsible members of the wider society. The analyses given are based on the students’ background and how it affects their performance in the nation education.Student profiles based on various indicators of academic achievement and school orientation: low-achieving and weakly oriented, (2) low-achieving and strongly oriented, (3) high-achieving and moderately oriented, (4) high achieving and strongly oriented. This analyses show that most of the Cuban American low achievers and this greatly contributed poor quality of the private school which most of this children attend to. The local community cannot be able to collect tax in order to sustain the development of quality education because they are poor and they don’t have property where they can collect tax.(Jeanne, 2004) Most of children coming from the diverse backgrounds in the United States mostly attend the public school, which are able to offer the young learners with the first language skills. The children who speak language other than English come from working class homes. The public schools as such consider the individual needs of the different races within the United States by providing education for the minority of the different cultural backgrounds. Most private school usually use English as the only medium of communication and as such they charge highly.New York’s Lycee Francais uses French extensively; on the other hand Miami’s Loyola school uses Spanish extensively as the medium of communication. This shows that there is a big difference between the public schools and the private school in the United States in vary many divergent ways. This paper endeavors to present a vivid analysis of such trends of education their weaknesses, their strengths in relation the diverse culture. Dade country, Florida comprises the many cities such as Miami and Hialeah and other surrounding areas mostly contain large numbers of Hispanic populations.Most of these Hispanic populations are coming from Cuba and few come from Spain and Mexico. These Hispanic people use Spain as the language as the medium of communication. These schools within this context use Spanish language as the medium] of communication; they basically run by people of the Cuban origin. The schools, which offer such services in this Spanish language, are usually the public schools. The private schools are deemed to be expensive and they are for the elite people. The whole of this region there were two elite schools commonly attended by the Cuban American children whose parents enjoy the upper class status.The public school have been referred as ethic schools meant for the low income earners and in this region most people are very poor and as such they take their children to this public school. Those members of this similar region who enjoy the high economic statuses take their children to the private school basically meant for elite members of the c ommunity. Bilingual education policy has been a unity force in the United States. The children of Cuban American origin receive instructions at school in Spanish, which considered as their first language.The public schools prefer the use of the learners’ first language. This has created linguistic and curriculum disparity within the system of education. For instance the Cuban American children become more proficiency in Spanish than English. This denies Cuban American children a chance to communicate effectively later since the official language for communication in the United States is English. The current shift in terms of the education system is towards the bilingual education policy practice, which has been found to be the most effective way of considering the minority.Here the learners are given an opportunity to study under the many languages. For instance those children from the Spanish origin are allowed to study using Spanish and English. The English in this context is taught as the second language. The United States federal government supports such program of bilingual education, which is aimed at promoting equity and unity among the citizens. However it is factual that the bilingual education system has also created structures that perpetuate social and political divisions.In addition the bilingual education policy has been known as the major hindrance to the development of the English language. The first and second languages can be developed simultaneously in such public school setting. Despite the reforms, children and the teachers have not changed their behavior of cultural identity. The changes have not been implemented especially from the part of teachers and the communities. The inability to speak and understand English has denied most the native speakers national opportunities denying them a chance to participate actively in the education issues of national nature.The curriculum design has such is not uniform at all since the media of instructions use different divergent languages. In terms of curriculum there are different texts, teachers for students who use a different language than English. It was argued that there is no equality at all by providing students with the same facilities, textbooks, teachers and curriculum for students who do not understand English since they are bound to find their classroom lessons quite incomprehensible. This is considered imposition of rules that cannot assist an individual.The English basic skills are important in these public skills so as to equip the learner with necessary skills that can enhance national participation. But because the children cannot learn in a language they do not understand the first language should the initial medium of instruction and then English should be used as a second language. Education has the net effect of creating a better global economy, those who have done in the 21st century well. From this fundamental fact, 21st century is dependent on sc ience and technology that is why education is taking a new shift in the United States of America.The following are some of the indicators of the disparities experienced in the Cuban American education system. Inequity in School Financing School financing comes from three sources: Federal, state, and local funds (with most funds coming from states). Education has the largest expenditure in the state budget. Whether it is more expensive to educate Cuban Americans is not an issue for debate the issue is that the areas where Cuban American children reside are usually low-wealth areas that generate less funding from property taxes.In most cases, districts have to pass bond referendums to rebuild schools, which are often not supported by the general voting public. Therefore, school districts with concentrations of Cuban American students remain under funded and must seek other means of support. School Segregation and Poverty. Today, Cuban American students are experiencing higher rates of segregation in school systems than are any other group of students. A recent report of the Harvard Project on School Desegregation to the National School Boards Association describes the changing patterns of segregation and poverty.The study found that segregation by race is strongly correlated with segregation by poverty; and the study provides national data demonstrating that Cuban American students are much more likely than white students to be in schools that are segregated and poorly funded. Under representation of Cuban American among School Personnel Most of the administrators and educational policy makers are white who determine the nature of education system to be offered. A study conducted by Meier and Stuart, for instance, showed that Cuban American representation on school boards and in the teaching profession is of a very low number.On a general perspective there are too few Cuban American teachers, counselors, and administrators in the education system. Multicultural Training for School Personnel Teacher insensitivity to cultural and linguistic diversity often influences a student to become alienated from the school system teachers. Bilingual education is the use of two languages, one of which is English, as a means of instruction. This implies that an educator must be Spanish-speaking in order to be a good and effective instructor of Cuban American students. The problem can only be solved if enough teachers who have bilingual skills are recruited into the mainstream.Testing and Assessment. Many Latino students never reach their full potential due to inappropriate and inaccurate uses of testing and assessment. Conclusion It is recognized those generations of Cuban American students in U. S. public education are at risk due to serious inadequacies in the educational system. Thus far, the system has been unable to meet the needs of those students. Among other inequities, there continues to exist a disparity in school funding, a lack of effective B ilingual and ESL education programs, a lack of trained teachers, and a misuse of testing and assessment.The quality of education is always decreasing as time goes by in the Cuban Americans. These multiple factors have greatly contributed to decreasing rates of college attendance by the Cuban American students. This is because the educational structures favor the white and the rich people. Reforming of the public school is one very important way of promoting education of the Cuban American education. Testing and having a uniform curriculum will eventually decrease all these disparities caused by poverty and racial discrimination.Proper methods of funding the federal government should be considered to be the most suitable way of achieving common educational objectives. To address these issues and policy areas, effective educational models must incorporate high-quality standards, equitable financial support, and diverse language and cultural knowledge. Parent and school collaboration m ust be specified in all plans of action. Long-term, strategic plans must be developed through collaborative approaches with the public and private sectors at the local, state, and national level to monitor and to ensure a high standard of educational attainment among Cuban Americans.References Baker C.

Chemistry Of Liquid Crystal Displays Engineering Essay

Nanoscience includes the survey and creative activity of stuffs, devices, and systems by pull stringsing single atoms and molecules. It describes research where the characteristic dimension of 1 or more planes is less than 100 nanometres i.e. , 0.1 micrometers. As we know that all manufactured merchandises are made from atoms and the belongingss of those merchandises depend on how atoms are arranged in them. So if we can rearrange the atoms in: Coal we get diamonds or black lead. Sand ( adding a few other hint elements ) we get computing machine french friess. Dirt, H2O and air we can do murphies. Unlike their larger or â€Å" macro † opposite numbers, nanoparticles frequently display alone belongingss that may be of usage for assorted applications.Introduction to Liquid CrystalsThe survey of liquid crystals began ( 1888 ) when an Austrian phytologist, Friedrich Reinitzer observed that a stuff known as cholesteryl benzoate had two distinguishable runing points. In his experiments, Reinitzer increased the temperature of a solid sample and watched the crystal alteration into a brumous liquid. As he increased the temperature further, the stuff changed once more into a clear, crystalline liquid. Because of this early work, Reinitzer is credited with detecting a new province of affair – the liquid crystal province.What are Liquid Crystals?There are solids which when heated undergo two crisp stage transmutations one after the other. They foremost fuse aggressively giving turbid liquid and so once more every bit aggressively at higher temperature giving clear liquids. These alterations are precisely reversed on chilling at the same temperatures. The turbid liquid nevertheless show anisotropy ( i.e. , they have different physical belongingss in different waies ) . Anisotropy is observed peculiarly in their optical behaviour. Therefore they exhibit dual refractions and intervention forms in polarized visible radiation. True liquids, on the contrary, are isotropous ( i.e. , they have same belongingss in all waies ) . Since anisotropic belongingss are associated with crystalline province, the turbid liquids are called liquid crystals. And as they are neither solids nor liquids, hence, the term muscular province ( intending intermediate signifier, in Greek ) likely fits the best. But liquid crystal besides continues to be used even in present twenty-four hours literature. Obviously, an indispensable demand for mesomorphism to happen is that the molecule should be anisotropic in form, like rod or a phonograph record. Industrial Lubricants exist, more or less, in liquid crystalline, i.e. , muscular province. The proteins and fats besides exist or acquire changed into this province before digestion and are therefore easy assimilated into the organic structure. This province is believed to play an of import function in the nutritionary and other procedures. Note the mean alliance of the molecules for each stage in the undermentioned diagram. It is sometimes hard to find whether a stuff is in a crystal or liquid crystal province. Crystalline stuffs demonstrate long scope periodic order in three dimensions. By definition, an isotropic liquid has no orientational order. Substances that are non ordered as solids, yet have some grade of alliance are decently called liquid crystals.PHASES OF LIQUID CRYSTALSThere are two basic stages of Liquid Crystals:NEMATIC SMECTICLiquid crystals act like polarising filters. The orientationally ordered rod-like molecules in liquid crystals affect the polarisation of the familial visible radiation.What is Liquid Crystal DisplayaˆÂ ¦ ?A procedure of picture show which is based on liquid crystal bed sandwiched between two polarising crystalline glass beds. The crystals that are charged by transistors unfastened and close to let and barricade the transition of visible radiation. In a projection format, visible radiation is passed through the LCD panel, from an internal lamp, onto the screen and each crystal is represented by one pel.Types of LC DisplaysThere are the undermentioned types of Liquid Crystal Displaies: Activematrix liquid crystal show Cholesteric liquid crystal show Transflective liquid crystal show ST liquid crystal showApplications Of LCDTypes of Display Screens Used TodayThere are two basic types of show screens used in today ‘s clip that are as followers: Cathode Ray Tube Display Liquid Crystal DisplayWhat is CRT DisplayaˆÂ ¦ ?CRT Display is an parallel show device which uses a vacuity tubing that generates images, on a bed of phosphors driven by an negatron beam, inside the tubing.How Does CRT WorksaˆÂ ¦ ?CRTs work by lighting points of phosphor on the screen by firing a beam of negatrons from the dorsum of the tubing. At the rear of the tubing an emitter is present. A beam of negatrons is sent towards the screen at the forepart of the tubing, by the emitter. The beam of negatrons is passed through a magnetic field which targets it at specific place on the screen, at the forepart of the tubing. The screen in forepart of the tubing is coated with phosphor which glows when it is struck by negatron beam. The phosphor points are arranged in little groups of ruddy, green and bluish and by uniting these three primary colourss, any colour can be created.Advantages of CRTSing AngleDue to the glowing points being near to the surface of glass, each point is every bit bright from any sing angle.B. ) colour fidelityAs each point is self-illuminating, uneven lighting or screening angles would non do colour fluctuations across the surface of the screen.No â€Å" dead pels †CRT ‘s do n't endure from the job of â€Å" dead pels † that consequence Plasma and LCD shows because the procedure of pu ting down the phosphor points is really simple.Disadvantages of CRTWeightAs the CRT screens get larger, their glass must acquire thicker to defy the force per unit area of the vacuity inside which would ensue in telecastings weighing 100s of lbs.B. ) Phosphor Burn-inThe phosphor compounds which really create the seeable visible radiation in the CRT show become less aglow with usage. This is one of the chief grounds for why an old telecasting set expression dim. If the show is systematically used to demo the same image for a long period of clip, the image can acquire â€Å" burned in † to the screen and it appears as a darkened image whenever the show is turned on. This is a common issue in instances when the show is connected to a computing machine where the common screen elements such as bill of fares or Windowss may stay on the screen for a long period of clip. While the new sets use a no. of techniques to cut down the happening of burn-in drastically, the overall brightness of the show still diminishes over clip.c. ) SizeCRT shows are limited to size around 45 inches. They are besides deeper than about all other shows because the negatron gun is placed far plenty behind the screen such that the full surface can be hit by it. Earlier the negatron gun had a sweep angle of 90 grades but in the late 1990 ‘s many CRT ‘s started utilizing negatron guns with 100 grades arc, which allowed shorter tubings to be used.How Does Liquid Crystal Display WorksaˆÂ ¦ ?The liquid crystal show works by reflecting a changeless, pure white visible radiation, foremost through a liquid crystal â€Å" shutter † and so through a coloured filter to make each point ( pel ) on the show. Each pel is really made up of three of these points of ruddy, green, and blue, each. The liquid crystal â€Å" shutters † first base on balls the polarising the visible radiation in one way and so base on balls it through a bed of liquid crystal. The liquid crystals are used to revolve the polarisation of the light passing through them, when the current is applied and the sum of rotary motion is controlled by changing the current. The visible radiation is so passed through a colour filter for the remotion of other constituents of the white visible radiation, go forthing merely the coveted colourss. The colored ( and polarized ) visible radiation is so passed through a concluding polarizing filter which is rotated 90 grades with regard to the original polarizing filter. If the visible radiation had non been rotated, so no visible radiation would ‘ve passed through the 2nd polarizing filter and the point would look dark. If the visible radiation had been to the full rotated, so it would go through through the filter at maximal strength.Advantages of LCDThe advantages of a liquid crystal show are:FlatDue to the absence of any big tubing, the LCD is much thinner than a CRT show.LightweightBecause it requires a beginning of visible radiation and the lightweight LCD shutters, the liquid crystal show is much lighter than CRT shows.Low Power ConsumptionAlthough the light beginning is required to run at maximal power over the full surface of the show, LCD ‘s by and large use lesser energy to run than CRT shows. Nowadays LCD shows use LED backlights usage less energy than any other show.Disadvantages of LCDThe disadvantages of the Liquid crystal show are:Sing AngleBecause of the colour filters and liquid crystals sitting between the spectator and the light beginning, each pel on an LCD show exists in a little â€Å" box † that prevents visible radiation from shed blooding from one pel to another . The â€Å" walls † of these boxes block the line-of-sight between the light beginning and the spectator when viewed at an angle which reduces the sensed brightness of that pel. Newer and more expensive shows are utilizing shallower boxes to minimise this issue.Response TimeEarlier, LCD shows had been plagued by slow response times because of the liquid crystals taking clip to alter province which consequences in â€Å" blurring † or â€Å" streaking † of fast-moving images. Newer theoretical accounts do non endure from this show â€Å" slowdown † as much.Color fidelityLCD shows use a individual visible radiation beginning that eliminates each pel in the show equally. It is really hard to fabricate a visible radiation beginning which is equally illuminated across its full surface. Inexpensive LCD ‘s frequently have uneven illuming across the show. In add-on, on larger shows, the spectator ‘s angle from the show may change rather a spot from the centre to the borders of the screen. Because of this the pels near the borders appear darker because they are non being viewed head-on.ContrastAs the light beginning is ever â€Å" on † behind every point of the LCD, it is hard to wholly barricade the visible radiation at a given pel and accomplish true black.LCD Construction & A ; Terminology1. ) F substrate ( glass ) 2. ) Terminal 3. ) Section electrode 4. ) Common electrode 5. ) B substrate ( glass ) 6. ) Upper polarising home base 7. ) Orientation bed 8. ) Sealant 9. ) LC ( liquid crystal ) 10. ) Conducting stuff 11. ) Sealant 12. ) Inlet 13. ) Sing country 14. ) Lower polarising home base, or lower polarising home base and reflecting home base

How Technology Changed Society

Through the years, we've watched technology grow like a child budding into adulthood: It starts out mostly crying and pooping, then crawling, gradually learning to walk, and finally able to run at a speed we all wish we could keep up with. We've seen technology fail, and we've seen it succeed. We've poked fun at it when it doesn't make sense, and we've praised it when it's absolutely brilliant. We've yelled at it when it runs out of power, and we've fixed or replaced it when it gets run down.We treat technology as a family member—even if that is a little co-dependent. You can't blame us, though; it's certainly made aspects of our lives easier: We're no longer forced to send letters through the postal service, book vacations through travel agents, shop in stores, visit the library for research material, or wait for our photos to be developed. Thanks to technology, all of these activities can be performed either digitally or online.At the same time, though, technology can make l ife more convoluted—especially when something doesn't work right or doesn't do what it's supposed to: Say, for instance, a GPS device tells you to turn the wrong way on a one-way street (yikes! ), or a computer erases all of your important data (ouch! ). Unfortunately, it's not always easy to understand how a product or service works, not to mention whether or not to hold off on adopting it until a better, shinier thing comes along. A perfect example is the ever-evolving video format.We've gone from Betamax to VHS to DVD to HD DVD/Blu-ray to just Blu-ray (and everything in-between, of course). It can take years before a technology catches on, and even more time before we see a significant price drop. For the most part, however, technology does us more good than harm: It's reconnected us with old college roommates, helped us learn a foreign language, and encouraged us to exercise. Follow us as we look back at how technology has changed our lives—for the better and for t he worse—in terms of communication, computing, dining, entertainment, and travel.

Comparative law ii trade and foreign investment in china Essay

Comparative law ii trade and foreign investment in china - Essay Example In DFW needs to transfer new technology to ST, it shall offer technical assistance and key components and parts during the preliminary stage of production. The means of payment for the technical services shall be specified in the technology transfer contract. Eventually, ST shall produce the items purely with domestic components with the upgrading in their skills and increase in domestic supplies. The signed contract will end with the fulfillment of the quality and quantity requirements specified in it. Advantages DFW will improve competitiveness in the SEZ by influencing few features such as competence/skill, capital, exports, infrastructure, and technology. Transfer of technology with synergistic results are dependent on achieving "reasonable compatible" targets between developing countries and foreign companies. A technology transfer will generally profit the SEZ in one of two ways. It will provide to manage research and development to accelerate the creation of new technology. Th e other way a technology transfer can benefit SEZ is when it  can share  its technology with less-developed regions in an endeavor to assist them with essential technologies, such as infrastructure development or food production. Technology transfer will modernize the Shenzhen economy and change the way products are generated, so the region becomes more resourceful and productive within the global market system. Disadvantages Technology transfer involves the movement of material structure, knowledge, skills, organization, values, and capital from the place of production to the receiving site. The unseen features of technology, such as organization, skills, and knowledge might be much more decisive than the physical  element it is for the  effective  transfer of technology. The technology that is transferred must also denotes the transfer of knowledge to the recipients, instead of making them rely on continuous external inputs and help. The new technology must be socially t olerable and beneficial on numerous levels, in addition to the general capability of communities to uphold healthy and sustainable livelihoods. Technological advances tend to raise complexity and uncertainty, making end users dependent on dedicated experts, and construct new knowledge obstacles for probable investors. In cases of the transfer of multifaceted production technologies, knowledge and technical proficiency become important hurdles to the transfer. b) Turnkey contract DFW can enter into a turnkey contract with SZ for the construction of a computer manufacturing plant and semiconductor manufacturing plant in the SEZ region. In this case, DFW will be entirely be responsible for the costs of designing and building the plant including its start-up and its capacity to produce computers and semiconductor chips as specified in the contract. ST shall provide a construction site for the computer manufacturing plant and semiconductor manufacturing plant, the required approvals from the Shenzhen government, the maintenance, and operational staff. On the other hand, DFW shall provide all the technology, design, and engineering services for procurement, supply, installation of all equipment, staff training, start-up of the plant, and guarantee that ST can use the plant to produce

Population growth and natural resource availability Research Paper

Population growth and natural resource availability - Research Paper Example The awareness regarding the need of the production system is increasing day by day in order to incorporate the goals of sustainable development. For managing this it is important that the natural resources are renewable, as they are considered to be the indicators for sustainability of the economic dynamics. This approach indicates that the natural resources are considered to be a link between environment and societies. The more recent subject in discussion related to resources and population growth is considered to be the significance of the quality of environment which is measured by the absence of water and air pollution and the stock of forest in a particular region. According to this view, environment may not be considered as a factor which limits the productivity with the expansion of population but it would rather be defined as factor whose quality is degraded with the increase in population. The expanding population increases the need for an arable land; it is a main cause behind deforestation and also encourages the conversion of forests into land for using it for different purposes. It is also considered to be the major cause of air, water and land pollution. On the other side environmental degradation may impose an effect on the natural resources reducing the marginal product of the labor through promoting lower incomes (Hinrichsen and Robey). In the past, the alarming situation was considered to be the diminution of natural resources. There are many scientists who have been calculating that duration till which the reserves of oil and coal will last. Therefore at present the interaction between man and natural environment is considered to be a source of alarm. In every natural ecosystem, the increase in population imposes a great pressure on it. This pressure becomes more immense in case of the human population, as this increase is not just numerical but also brings along the diversification and creation of new needs. This qualitative

(Institutional Affiliation) FORMAL REPORT COMPARING THE USE OF THE Essay

(Institutional Affiliation) FORMAL REPORT COMPARING THE USE OF THE IDEF METHODOLOGY TO UML - Essay Example 1). On the other hand, UML is a modeling language that is most suited to the generation of computer-executable platforms/frameworks that encode important elements of software engineering projects. This paper will seek to compare the use of IDEF to UML by focusing on their applications, nature, and techniques employed in their development. This comparison will be done on the basis of credible and reliable literatures, written and published by authorities on modeling languages and techniques. Key Words IDEF; UML; graphical modeling methods; enterprise engineering projects; modeling language The Approach/Rationale of both Methodologies a) IDEF According to Bernus, Mertins, & Schmidt (1998, pg. 17), the rationale for IDEF is to support modeling activities that are fundamental to system analysis, design, improvement or integration. b) UML The approach/rationale for UML is to act as the dominant, publicly accepted, and uniform objected oriented visual modeling language, and as a foundation object description language for the offshoot unified enterprise modeling language (UEML) that has been put forward by IFAC/IFIP (Bernus, Mertins, & Schmidt 1998, pg. 17). The Stages of the Systems Development Life Cycle that each Addresses IDEF methodology addresses documentation, design, integration, analysis, understanding, planning, and improvement (Fowler & Scott 2000, pg. 46). Based on the Waterfall model of the system development life cycle (SDLC), these functions fit into four stages of the SDLC: preliminary analysis, system analysis and requirements definition, systems design, integration and testing, and maintenance. On the other hand UML methodology is limited to the systems design phase. During the systems analysis phase, object-oriented analysis (OOA) is performed; its output is a conceptual model that is comprised of one (sometimes more) UML class diagram, a user-interface mock-up, a group of use cases, and a couple of interaction diagrams. This conceptual model is sub sequently used as an input in objected-oriented design during the systems design phase (Lankhorst 2005, pg. 63). The Techniques used for modeling the Processes/Functions of the System (including the similarities and differences between the techniques and their strengths and weaknesses) a) IDEF Techniques IDEF is based on three modeling constructs/viewpoints/techniques which define its approach/rationale. These are: i) IDEF0 Function Modeling Method This method was created so as to represent processes or activities (consisting of partially sequenced groups of activities) that are usually executed in a systematic and uniform manner. IDEF0 defines a function as a group of activities that takes specific inputs and, using some mechanism, and based on certain controls, converts the inputs into outputs (Noran 2008, pg. 41). These ICOMs (inputs, controls, outputs and mechanisms) can be employed in the modeling of relationships between a wide range of activities (Kim 2003, pg. 3). IDEF0 mode ling generally begins by defining a context diagram (Kim 2003, pg. 3). This is representative of the system’s overall purpose and its interactions with external environments (Kim 2003, pg. 3). Usually, IDEF0 models consist of a hierarchy of connected diagrams that are decomposed systematically hence encoding semantic data at lower modeling levels. The systematical breakdown brings not only detailed but also wide-scope representations of system or environmental activities (Bernus, Mertins, & Schmidt 1998, pg. 29). ii) IDEF1x Data Modeling Method This method was created to define data models that symbolize both the semantics and structure of data that is found in a target system

Information Security and Ethics Essay Example | Topics and Well Written Essays - 1000 words

Information Security and Ethics - Essay Example Professional ethics plays crucial role in helping information security professional to execute their duty. However, to ensure maximum information security, organizations need to institute relevant legislations to guard against information security breach. This paper explores policies and procedure that organizations should implement to secure their confidential information. It is crucial that security forms an integral part of organizational culture. Protecting the firm from possible information security breach should be a major focus of the company’s operational process. To achieve this, security policies or e-policies provide the fundamental framework for an organization to beef security over its crucial information. Security policies are regulations that outline how organizational information are supposed to be used in executing daily organizational tasks and also dictate who is authorized to access what information. What Are Security Policies or e-policies? A security poli cy can be referred to as a document that gives guidelines on how an organization intends to protect its physical as well as information technology assets. According to Ciampa (2010), a security policy refers to â€Å"a document that outlines the protections that should be enacted to ensure the organization’s assets face minimal risks.†An organization’s security policy is usually referred to as a living document because it is continuously upgraded to meet emerging organizational challenges in the face of organizational change and evolving employee requirements. The security policy of an organization usually reflects on policy implementation requirements and possible corrections in case loopholes are detected (Ciampa, 2010). Recommended Information Security Policies for Organizations Control over Access to Computer Rooms In order to ensure high level security for crucial organizational information, computer rooms should be kept under lock and key at all times. Com puter rooms should have doors fitted strongly and manned by security officers at all times. In addition to locking computer rooms, there should be security officers deployed to man the doors to main information areas. Only authorized personnel should access such rooms through user authentication process. Use of Passwords and Authentication Procedures The organization should have documented guidelines to control access over its crucial information areas. All computers in the organization should have passwords in relation to security demands. These guidelines need to be assessed on regular intervals. The guidelines should have password requirement and control the storage of such passwords. All users of information accessing information system of the company must be authenticated. Individuals who are authorized to access company information should have unique blend of usernames and passwords to bar unauthorized personnel or external intruders from gaining easy access to the organizatio n’s private information. Information users are held responsible for the usage of their passwords and usernames, which they should keep secret unless called upon by the chief security officer to disclose such passwords and usernames. Data Encryption Policy The second policy that an organization can establish to protect its valuable information is data encryption. In recent times, there have been numerous
