Political Transitions in East and South East Asia Essay - 1

Political Transitions in East and South East Asia - Essay Example It is considered undemocratic in the event that people are respected and dignified selectively and with discriminatory perspectives. This concept of democracy illustrates that on some occasions the welfare of one or just a couple of people can be subordinated by the interests of the majority in order to achieve a common good. It is important to note that democracy does not it whatever circumstances promote equality of condition like in communism. Equality of condition comes with favoritism and categorization into groups of similar characteristics. On the other hand, democracy promotes equality of opportunity. According to equality of opportunity, everyone has then freedom to develop his or her talent to totality or as much as he or she cares to. Democracy is founded on the principle that the majority is more often right that wrong. When it comes to politics, democracy dictates that the majority is better positioned to make sane political decisions as compared to the minority or a single individual. One ought to note that sometimes democracy is seen as a trial and error process in which some decisions may not be absolute best but eventually become satisfactory because of its support from then majority faction. Despite the fact that democracy seems to dwell so much on the majority, it is noteworthy that it does not overlook the minority entirely. On the other hand, democracy gives some respect to the minority. This is done by giving then minority a chance to join the majority faction through legal means. Additionally, democracy also ensures that then minority in a society is given equal chance as the majority to voice its views. Compromising can be defined as the process of adjusting, reconciling and blending competing views with the aim of finding common ground that is most acceptable to the largest number of stakeholders involved. Democracy demands for the

The terms Race and Ethnicity Essay Example for Free

The terms Race and Ethnicity Essay The terms Race and Ethnicity are vastly different in meaning. Regardless of their historical definitions which can be lengthy and tend to run off on many tangents. Race to me simply is based on physical characteristics. The color of ones skin, the bone structure, eye color and shape, or texture and color of ones hair. The physical makeup of a person determines their origin of race, for example Black, White or Asian. Race is simply our biological composition. Ethnicity on the other hand is based in culture, where a persons ancestry developed, their national origin being foremost and then their learned culture and background over time becomes ones ethnic makeup. Examples of this are Hispanic, German, Scottish, English, Mexican, or Jewish. For instance I am White but also German, Irish and Dutch and through my family history there are cultural traditions carried on in each generation that have become part of my ethnicity and make me unique but also group me with people from my -specific ethnic background. Ethnicity means sharing cultural similarities such as language, cuisines, dress and traditions that are part of a national culture. As far as the ways these concepts are important to the United States society, there are many, however not all of them are positive. These concepts are important to the United States society because people are recognized for the diversity of their race and culture as represented by each individual group. In my opinion race has been and is still used to determine power in our society and always brings separation by the ways in which its distributed. Classes are formed and people are either lifted to a higher level of class based on their skin color or race of origin and others are suppressed and disallowed to climb higher in society by the same racial definitions. I believe the biggest importance in our society regarding both race and ethnicity is the way people are treated regarding healthcare and the glaring class separation. Whole sections of people can be made to feel alienated or be made to feel inferior if society fails to bring diverse groups together as one mainstream society. Ethnicity as I have seen it has brought groups closer in society. People of diverse nationalities seem to stick together and celebrate their diversity in close knit groupings, gathering at holidays to share cultural traditions. Choosing cohabitation in neighborhoods of common nationalities and cultures, forming alliances with similar fellowships and even encouraging social activities within cultural groups. Everyone can learn from anothers culture and bring their own knowledge to the table to share with others. Our country was founded on diversity and the common understanding that we are all different and all deserve the same respect for our individual values. In order to ensure success in the future of our country we need to broaden our thinking and teach tolerance and appreciation for our differences.

Strategies for Welding Aluminium

Strategies for Welding Aluminium CHAPTER 1: INTRODUCTION 1.1 INTRODUCTION OF THE FSW TECHNIQUE In todays modern world there are many different welding techniques to join metals. They range from the conventional oxyacetylene torch welding to laser welding. The two general categories in which all the types of welding can be divided is fusion welding and solid state welding. The fusion welding process involves chemical bonding of the metal in the molten stage and may need a filler material such as a consumable electrode or a spool of wire of the filler material, the process may also need a inert ambience in order to avoid oxidation of the molten metal, this could be achieved by a flux material or a inert gas shield in the weld zone, there could be need for adequate surface preparations, examples of fusion welding are metal inert gas welding (MIG), tungsten inert gas welding (TIG) and laser welding. There are many disadvantages in the welding techniques where the metal is heated to its melting temperatures and let it solidify to form the joint. The melting and solidification causes the mechanical properties of the weld to deteriorate such as low tensile strength, fatigue strength and ductility. The disadvantages also include porosity, oxidation, microsegregation, hot cracking and other microstructural defects in the joint. The process also limits the comb ination of the metals that can be joined because of the different thermal coefficients of conductivity and expansion of different metals. The solid state welding is the process where coalescence is produced at temperatures below the melting temperatures of the base metal with out any need for the filler material or any inert ambience because the metal does not reach its melting temperature for the oxidation to occur, examples of solid state welding are friction welding, explosion welding, forge welding, hot pressure welding and ultrasonic welding. The three important parameters time, temperature and pressure individually or in combinations produce the joint in the base metal. As the metal in solid state welding does not reach its melting temperatures so there are fewer defects caused due to the melting and solidification of the metal. In solid state welding the metals being joined retain their original properties as melting does not occur in the joint and the heat affected zone (HAZ) is also very small compared to fusion welding techniques where most of the deterioration of the strengths and ductility begins. Dissimila r metals can be joined with ease as the thermal expansion coefficients and the thermal conductivity coefficients are less important as compared to fusion welding. Friction stir welding (FSW) is an upgraded version of friction welding. The conventional friction welding is done by moving the parts to be joined relative to each other along a common interface also applying compressive forces across the joint. The frictional heat generated at the interface due to rubbing softens the metal and the soft metal gets extruded due to the compressive forces and the joint forms in the clear material, the relative motion is stopped and compressive forces are increased to form a sound weld before the weld is allowed to cool. Friction stir welding is also a solid state welding processes; this remarkable upgradation of friction welding was invented in 1991 in The Welding Institute (TWI) [4]. The process starts with clamping the plates to be welded to a backing plate so that the plates do not fly away during the welding process. A rotating wear resistant tool is plunged on the interface between the plates to a predetermined depth and moves forward in the interface between the plates to form the weld. The advantages of FSW technique is that it is environment friendly, energy efficient, there is no necessity for gas shielding for welding Al, mechanical properties as proven by fatigue, tensile tests are excellent, there is no fume, no porosity, no spatter and low shrinkage of the metal due to welding in the solid state of the metal and an excellent way of joining dissimilar and previously unweldable metals. 1.2 ALUMINUM ALLOYS AND WELDING OF ALUMINUM ALLOYS Aluminum is the most abundant metal available in the earths crust, steel was the most used metal in 19th century but Aluminium has become a strong competitor for steel in engineering applications. Aluminium has many attractive properties compared to steel it is economical and versatile to use that is the reason it is used a lot in the aerospace, automobile and other industries. The most attractive properties of aluminum and its alloys which make them suitable for a wide variety of applications are their light weight, appearance, frabricability, strength and corrosion resistance. The most important property of aluminum is its ability to change its properties in a very versatile manner; it is amazing how much the properties can change from the pure aluminum metal to its most complicate alloys. There are more then a couple of hundreds alloys of aluminum alloys and many are being modified form them internationally. Aluminium alloys have very low density compared to steel it has almost on e thirds the density of steel. Properly treated alloys of aluminum can resist the oxidation process which steel can not resist; it can also resist corrosion by water, salt and other factors. There are many different methods available for joining aluminum and its alloys. The selection of the method depends on many factors such as geometry and the material of the parts to be joined, required strength of the joint, permanent or dismountable joint, number of parts to be joined, the aesthetic appeal of the joint and the service conditions such as moisture, temperature, inert atmosphere and corrosion. Welding is one of the most used methods for aluminum. Most alloys of aluminum are easily weldable. MIG and TIG are the welding processes which are used the most, but there are some problems associated with this welding process like porosity, lack of fusion due to oxide layers, incomplete penetration, cracks, inclusions and undercut, but they can be joined by other methods such as resistance welding, friction welding, stud welding and laser welding. When welding many physical and chemical changes occur such as oxide formation, dissolution of hydrogen in molten aluminum and lack of color change when heated. The formation of oxides of aluminum is because of its strong affinity to oxygen, aluminum oxidizes very quickly after it has been exposed to oxygen. Aluminum oxide forms if the metal is joined using fusion welding processes, and aluminum oxide has a high melting point temperature than the metal and its alloys it self so it results in incomplete fusion if present when joined by fusion welding processes. Aluminum oxide is a electrical insulator if it is thick enough it is capable of preventing the arc which starts the welding process, so special methods such as inert gas welding, or use of fluxes is necessary if aluminum has to be welded using the fusion welding processes. Hydrogen has high solubility in liquid aluminum when the weld pool is at high temperature and the metal is still in liquid state the metal absorbs lots of hydrogen which has very low solubility in the solid state of the metal. The trapped hydrogen can not escape and forms porosity in the weld. All the sources of hydrogen has to be eliminated in order to get sound welds such as lubricants on base metal or the filler material, moisture on the surface of base metal or condensations inside the welding equipment if it uses water cooling and moisture in the shielding inert gases. These precautions require considerable pretreatment of the workpiece to be welded and the welding equipment. Hot cracking is also a problem of major concern when welding aluminum, it occurs due to the high thermal expansion of aluminum, large change in the volume of the metal upon melting and solidification and its wide range of solidification temperatures. The heat treatable alloys have greater amounts of alloying elements so the weld crack sensitivity is of concern. The thermal expansion of aluminum is twice that of steel, in fusion welding process the melting and cooling occurs very fast which is the reason for residual stress concentrations. Weldability of some aluminum alloys is an issue with the fusion welding processes. The 2000 series, 5000 series, 6000 series and 7000 series of aluminum alloys have different weldabilities. The 2000 series of aluminum alloys have poor weldability generally because of the cooper content which causes hot cracking and poor solidification microstructure and porosity in the fusion zone so the fusion welding processes are not very suitable for these alloys. The 5000 series of aluminum alloys with more than 3% of Mg content is susceptible to cracking due to stress concentration in corrosive environments, so high Mg alloys of 5000 series of aluminum should not be exposed to corrosive environments at high temperatures to avoid stress corrosion cracking. All the 6000 series of aluminum are readily weldable but are some times susceptible to hot cracking under certain conditions. The 7000 series of aluminum are both weldable and non-weldable depending on the chemical composition of the alloy. Alloys with low Zn-Mg and Cu content are readily weldable and they have the special ability of recovering the strength lost in the HAZ after some weeks of storage after the weld. Alloys with high Zn-Mg and Cu content have a high tendency to hot crack after welding. All the 7000 series of aluminum have the sensitivity to stress concentration cracking. All these problems associated with the welding of these different alloys of aluminum has lead to the development of solid state welding processes like Friction Stir Welding technique which is an upgraded version of the friction welding processes. This process has many advantages associated with it, and it can weld many aluminum alloys such as 2000 and 7000 series which are difficult to weld by fusion welding processes. The advantages of the Friction Stir Welding processes are low distortion even in long welds, no fuse, no porosity, no spatter, low shrinkage, can operate in all positions, very energy efficient and excellent mechanical properties as proven by the fatigue, tension and bend tests. 1.3 Conventional Welding Processes of Aluminum A brief description of the most common processes, their applications on aluminum and limitations are given below. 1.3.1 Gas Tungsten Arc Welding (GTAW): In gas tungsten arc welding process the heat generated by an arc, which is maintained between the workpiece and a non-consumable tungsten, electrode is used to fuse the joint area. The arc is sustained in an inert gas, which serves to protect the weld pool and the electrode from atmospheric contamination as shown in Figure 2.3. The process has the following features: It is conducted in a chemically inert atmosphere; The arc energy density is relatively high; The process is very controllable; Joint quality is usually high; Deposition rates and joint completion rates are low. The process may be applied to the joining of a wide range of engineering materials including stainless steel, aluminum alloys and reactive metals such as titanium. These features of the process lead to its widespread application in aerospace, nuclear reprocessing and power generation industries as well as in the fabrication of chemical process plant, food processing and brewing equipment. 1.3.2 Shielded metal arc welding (SMAW): Shielded metal arc welding has for many years been one of the most common techniques applied to the fabrication of steels. The process uses an arc as the heat source but shielding is provided by gases generated by the decomposition of the electrode coating material and by the slag produced by the melting of mineral constituents of the coating. In addition to heating and melting the parent material the arc also melts the core of the electrode and thereby provides filler material for the joint. The electrode coating may also be used as source of alloying elements and additional filler material. The flux and electrode chemistry may be formulated to deposit wear- and corrosion-resistant layers for surface protection as shown in Figure 2.4. Significant features of the process are: Equipment requirement are simple; A large range of consumables are available; The process is extremely portable; The operating efficiency is low; It is labor intensive. For these reasons the process has been traditionally used in structural steel fabrication, shipbuilding and heavy engineering as well as for small batch production and maintenance. 1.3.3 Plasma welding: Plasma welding uses the heat generated by a constricted arc to fuse the joint area; the arc is formed between the tip of a non-consumable electrode and either the work piece or the constricting nozzle as shown in Figure 2.5. A wide range of shielding and cutting gases is used depending on the mode of operation and the application. In the normal transferred arc mode the arc is maintained between the electrode and the work piece; the electrode is usually the cathode and the work piece is connected to the positive side of the power supply. In this mode a high energy density is achieved and the process may be used effectively for welding and cutting. The features of the process depend on the operating mode and the current, but in summary the plasma process has the following characteristics: Good low-current arc stability Improved directionality compared with GTAW Improved melting efficiency compared with GTAW Possibility of keyhole welding The keyhole technique is the high heat concentration can penetrate completely through the joint. These features of the process make it suitable for a range of applications including the joining of very thin materials, the encapsulation of electronic components and sensors, and high- speed longitudinal welds on strip and pipe. 1.3.4 Laser welding The laser may be used as an alternative heat source for fusion welding. The focused power density of the laser can reach 1010 or 1012 Wm-2 and welding is often carried out using the keyhole technique. Significant features of laser welding are: Very confined heat source at low power Deep penetration at high power Reduced distortion and thermal damage Out-of-vacuum technique High equipment cost These features have led to the application of leaders for micro joining of electronic components, but the process is also being applied to the fabrication of automotive components and precision machine tool parts in heavy section steel. 1.4 Weld Defects using Conventional Processes Because of a history of thermal cycling and attendant micro structural changes, a welded joint may develop certain discontinuities. Welding discontinuities can also be caused by inadequate or careless application of established welding technologies or substandard operator training. The major discontinuities that affect weld quality are described below. 1.4.1 Porosity: Trapped gases released during melting of the weld area and trapped during solidification, chemical reactions during welding, or contaminants, cause porosity in welds. Most welded joints contain some porosity, which is generally spherical in shape or in the form of elongated pockets. The distribution of porosity in the weld zone may be random, or it may be concentrated in a certain region. Porosity in welds can be reduced by the following methods: Proper selection of electrodes and filler metals. Improving welding techniques, such as preheating the weld area or increasing the rate of heat input. Proper cleaning and preventing contaminants from entering the weld zone. Slowing the welding speed to allow time for gas to escape.8 1.4.2 Slag inclusions: Slag inclusions are compounds such as oxides, fluxes, and electrode-coating materials that are trapped in the weld zone. If shielding gases are not effective during welding, contamination from the environment may also contribute to such inclusions. Welding conditions are important, and with proper techniques the molten slag will float to the surface of the molten weld metal and not be entrapped. Slag inclusions may be prevented by: Cleaning the weld-bead surface before the next layer is deposited by using a hand or power wire brush. Providing adequate shielding gas. Redesigning the joint to permit sufficient space for proper manipulation of the puddle of molten weld metal. 1.4.3. Incomplete fusion and penetration: A better weld can be obtained by: Raising the temperature of the base metal. Cleaning the weld area prior to welding. Changing the joint design and type of electrode. Providing adequate shielding gas. Incomplete occurs when the depth of the welded joint is insufficient. Penetration can be improved by: Increasing the heat input. Lowering travel speed during welding. Changing the joint design. Ensuring that surfaces to be joined fit properly.8 1.4.4 Weld profile: Weld profile is important not only because of its effects on the strength and appearance of the weld, but also because it can indicate incomplete fusion or the presence of slag inclusions in multiple-layer welds. Under filling results when the joint is not filled with the proper amount of weld metal Figure 2.7. Undercutting results from melting away the base metal and subsequently generating a groove in the shape of recess or notch. Unless it is not deep or sharp, an undercut can act as a stress raiser and reduce the fatigue strength of the joint and may lead to premature failure. Overlap is a surface discontinuity generally caused by poor welding practice and selection of the wrong materials. A proper weld is shown in Figure 2.7c.5 1.4.5 Cracks: Cracks may occur in various locations and direction in the weld area. The types of cracks are typically longitudinal, transverse, crater, and toe cracks Figure 2.8. These cracks generally result from a combination of the following factors: Temperature gradients that cause thermal stresses in the weld zone. Variations in the composition of the weld zone that cause different contractions. Embitterment of grain boundaries by segregation of elements, such as sulfur, to the grain boundaries as the solid-liquid boundary moves when the weld metal begins to solidify. Hydrogen embitterment. Inability of the weld metal to contract during cooling is a situation similar to hot tears that develops in castings and related to excessive restraint of the work piece. (a) crater cracks. (b)Various types of cracks in butt and T joints.8 Cracks are classified as hot or cold cracks. Hot cracks occur while the joint is still at elevated temperatures. Cold cracks develop after the weld metal has solidified. Some crack prevention measures are: Change the joint design to minimize stresses from shrinkage during cooling. Change welding-process parameters, procedures, and sequence. Preheat components being welded. Avoid rapid cooling of the components after welding.8 1.4.6 Lameller tears: In describing the anisotropy of plastically deformed metals, we stated that because of the alignment of nonmetallic impurities and inclusions (stringers), the work piece is weaker when tested in its thickness direction. This condition is particularly evident in rolled plates and structural shapes. In welding such components, lamellar tears may develop because of shrinkage of the members in the members or by changing the joint design to make the weld bead penetrate the wearer member more deeply.8 1.4.7 Surface damage: During welding, some of the metal may spatter and be deposited as small droplets on adjacent surfaces. In arc welding possess, the electrode may inadvertently contact the parts being welded at places not in the weld zone (arc strikes). Such surface discontinuities may be objectionable for reasons of appearance or subsequent use of the welded part. If severe, these discontinuities may adversely affect the properties of the welded structure, particularly for notch-sensitive metals. Using proper welding techniques and procedures is important in avoiding surface damage.8 1.5 Skill and Training requirements: Many of the traditional welding processes required high levels of operator skill and dexterity, this can involve costly training programs, particularly when the procedural requirement described above need to be met. The newer processes can offer some reduction in the overall skill requirement but this unfortunately been replaced in some cases by more complex equipment and the time involved in establishing the process parameters has brought about a reduction in operating factor. Developments, which seek to simplify the operation of the equipment, will be described below but effective use of even the most advanced processes and equipment requires appropriate levels of operator and support staff training. The cost of this training will usually be recovered very quickly in improved productivity and quality. 1.6 Areas for development: Advances in welding processes may be justified in: Increased deposition rate; Reduced cycle time; Improved process control; Reduced repair rate; Reduced weld size; Reduced joint preparation time; Improved operating factor; Reduction in post-weld operations; Reduction in potential safety hazards; Removal of the operator from hazardous area; Simplified equipment setting. Some or all these requirement have been met in many of the process developments which have occurred in the ten years; these will be described in detail in the following chapters but the current trends in the of this technology are examined below. 1.7 New processes: The Primary incentive for welding process development is the need to improve the total cost effectiveness of joining operations in requirement for new processes. Recently, concern over the safety of the welding environment and the potential shortage of skilled technicians and operator in many countries have become important considerations. Many of the traditional welding techniques described in this Chapter are regarded as costly and hazardous and it is possible to improve both of these aspects significantly by employing some of the advanced process developments described in the following chapters. The use of new joining techniques such as Friction Stir Welding appears to be increasing since it does not involve melting. The application of these processes has in the past been restricted, but with the increased recognition of the benefits of automation and the requirement for high-integrity joints in newer materials it is envisaged that the use of these techniques will grow. This is a new process originally intended for welding of aerospace alloys, especially aluminum extrusions. Whereas in conventional friction welding, heating of interfaces is achieved through friction by rubbing two surfaces, in the FSW process, a third body is rubbed against the two surfaces to be joined in the form of a small rotating non-consumable tool that is plunged into the joint. The contact pressure causes frictional heating. The probe at the tip of the rotating tool forces heating and mixing or stirring of the material in the joint. 1.8 Research objectives: The objectives of our project are to: Adopt FSW to a milling machine Design the FSW tools, select its material and have it manufactured Design the required clamping system Apply FSW to plates of an alloy that is not readily weldable by conventional methods Investigate FSW parameters (RPM, Feed Rate and Axial force) Analyze conventionally welded and Friction Stir welded sections then compare their properties. The objective of this research is to characterize the mechanical properties of friction stir welded joints and study the micro structure of the base metal and the weld nugget evolved during the friction stir welding of similar and dissimilar alloys of Aluminum. Aluminum 2024 and 7075 are considered for this investigation. The mechanical properties such as ultimate tensile strength, yield strength, formability, ductility and vickers hardness are measured and an effort is made to find out a relation between the process variables and properties of the weld. The optimal process parameters for the Friction-Stir welding of AA2024 and AA7075 will be defined based on the experimental results. Having understood the significance of FSP, the main objective of this thesis is to investigate the effect of process parameters like rotational and translational speeds on the forces generated during FSP of aluminum alloys and relate these forces with the microstructure evolved in order to optimize the process. The specific objectives of the work presented are: Design and conduct FS processing experiments on aluminum alloy for different combinations of rotational and translation speeds. Measuring the generated processing forces during FSP of aluminum alloys Examine the microstructural of the processed sheets using transmission electron microscope (TEM). Attempt to establish a correlation between these measured forces and the resulting microstructure. Chapter 2 Review of Literature 2.1 General Idea of the Friction Stir Technology This section gives an insight into the innovative technology called friction stir technology. The action of rubbing two objects together causing friction to provide heat is one dating back many centuries as stated by Thomas et.al [1]. The principles of this method now form the basis of many traditional and novel friction welding, surfacing and processing techniques. The friction process is an efficient and controllable method of plasticizing a specific area on a material, and thus removing contaminants in preparation for welding, surfacing/cladding or extrusion. The process is environmentally friendly as it does not require consumables (filler wire, flux or gas) and produces no fumes. In friction welding, heat is produced by rubbing components together under load. Once the required temperature and material deformation is reached, the action is terminated and the load is maintained or increased to create a solid phase bond. Friction is ideal for welding dissimilar metals with very different melting temperatures and physical properties. Some of the friction stir technologies ar e shown in the Fig.2-1. Work carried out at TWI by Thomas et.al [2,3] has demonstrated that several alternative techniques exist or are being developed to meet the requirement for consistent and reliable joining of mass production aluminum alloy vehicle bodies. Three of these techniques (mechanical fasteners, lasers and friction stir welding) are likely to make an impact in industrial processing over the next 5 years. FSW could be applied in the manufacture of straight-line welds in sheet and extrusions as a low cost alternative to arc welding (e.g. in the fabrication of truck floors or walls). The development of robotized friction stir welding heads could extend the range of applications into three dimensional components. Mishra et.al [4] extended the FSW innovation to process Al 7075 and Al 5083 in order to render them superplastic. They observed that the grains obtained were recrystallized, equiaxed and homogeneous with average grain sizes

Impact of the Computer and Internet on Parks and Recreation Management :: Expository Essays

Impact of the Computer and Internet on Parks and Recreation Management The invention of the computer and the Internet system has greatly advanced and/or changed many of the careers through out the world. Parks and Recreation Management is one of these occupations that have been able to thrive with the Internet and personal computers available today. Recreation today is becoming more and more popular due to an overall decrease in working hours. These shorten working hours leave more free time and have recently made the recreation occupation more popular. With the many national, state, and private parks in the United States, it is essential for the park systems to figure out a way to become organized and more nation-wide known due to the competition. The Internet and use of the computer became the answer to these problems. The State and National Parks System developed a database computer system that makes registration easier and faster than in the past. Instead of filling out multiple registration slips one at a time, an employee is able to type the register’s information in, and in seconds their registration slips come out neatly and accurately by computer. There is a company that takes calls for the government parks system to make reservations but recently with the discovery of the Internet, campers now are able to reserve a camping site from their own homes. This [1]park database is automatically revised every time the company, the campers, or the park rangers themselves make a reservation from the park. This keeps the state and national park system organized and more easily accessible to make reservations. With this improvement in speed and accuracy with reservations, park rangers have more time to enforce laws and regulations then being consumed with unnecessary problems in the office. Because of the increase of the populations in the state and national parks, park rangers have their hands full and cannot always be available to make reservations at the park office. This gives more face-to-face communication between park ranger and customer. Similar with other careers, the Internet has become a very useful source in Parks and Recreation Management. With their own website, the [2]national and [3]state park systems are more able to inform people about upcoming rules and regulations and new developments in different parks.

Program Planning and Evaluation

Program planning is the starting blue prints or structure of a new program or even used to improve a program already in place. Program planning involves research, making goals, setting up objectives in order to meet goals and gathering information. Program planning also includes information about the budget such as how much it will cost in order to provide the services intended by the program. Program planning tells us what the problem is, who the program targeted population is, where are the targeted population demographically located, and why there is a problem. Program planning involves a lot of thought and information collected by the staff and where available the clients as well. Program planning determines what obstacles the program may encounter along the way and plans to work around the obstacles. Program planning should be done carefully and thoroughly because as a blue print for a program we would like the finishing product to be very well built and organized with a great finished product. Program evaluation is the ongoing collection of data which the staff of the program can take into consideration when making changes for necessary improvements or for future planning of the program. Program evaluations show the staff the strong points of the program they may wish to leave alone and also the weak points of the program they may need to make stronger. Program evaluation is important because it helps to keep the program running smoothly in order to meet their goals and provide sufficient services to the community and clients that the program serves. Program planning and program evaluations work together in order to make a program effective and efficient. Program planning does not stop just because a program is up and running since there will always be changes that need to be made as the program grows and needs to meet the demands of more clients and becomes a bigger part of the community it serves. Therefore program evaluations continue to help keep the program planning on a proper level and help the staff make decisions needed in order to meet demands and still plan goals and objectives successfully. The scenario I have chosen to work with this year is the PEACE Domestic Violence Agency. I believe that both program planning and program evaluation interrelate in this scenario because there is a growing problem with violence in the city of Portland and without action it will probably become worse. There needs to be a program in place in order to give any means of help to the community that can be offered and that will require program planning. The continuous changes of needs, and the need to ensure effectiveness is going to require the implementation of program evaluations in order to help measure the success and continue make the success rates higher. The technical aspects of program planning should consist of inputs to outputs that would in turn provide the community the social justice needed. I believe that the technical aspects are to make a crisis hotline available which would provide 24 hour access to a staff member who can help. I believe that there should be qualified counselors staffed within the program in order to help the individual to identify needs and also to obtain protection orders if necessary. I think that having a shelter or an affiliated shelter would be helpful because some clients are going to need a place to stay and receive a chance at a fresh start through transitional housing. Further I believe that technical aspects would be to also get some community awareness started about violence and ways to prevent it. This can be a fun community activity during which individuals learn to look out for one another instead of hurting one another or turning the other way while someone else is hurt. On the other hand there needs to be rehabilitation for the individuals who act violently. Enabling them to lead a better life and teaching them to protect others instead of causing harm. Aspects that can affect the program planning and evaluation process are that there might be some people still too afraid to come forward and fight for the changes that benefit them. They might have their doubts that the program will work because the violence rates are so high and so many people have failed to fully help them. A person who has been a victim might be inclined to move on but become victim again. A person hurting others may be inclined to feel there is no need for them to get help. The way these aspects can affect the program planning and program evaluation are because they are obstacles that would prevent the program from becoming successful and promoting a better outcome for individuals and the community. In order to prevent hindering the program we have to find other ways to get through and rebuttal the situations. Political aspect of the program planning and evaluation would be to ask for harder punishment for those who are on the violent side of the fence. I would also ask for more police involvement in the community and if needed be the hiring of more police authority in the area to help in lowering the amount of time it takes to get to a situation involving violence. I would ask for education about violence to be implemented through school systems and jail or prison facilities to raise the possibility of positive changes. I would ask for cameras to be placed at stop lights and in other areas where road rage was the worst in order to help in providing proper apprehending of drivers who have a problem. These aspects could affect planning and evaluation of the program because political authorities might not feel there is enough violence to take action. It also could affect the planning and evaluation because the political authorities might not have the funds to provide the help needed. The political authorities might agree to the needs but on lesser terms. This would mean that in order to have success rates we are looking for we need to find other ways to get the help needed.

Communication is an aspect of life that all people, young and old, need in their lives as there are endless possibilities of expressing one’s emotions Introduction Communication is an aspect of life that all people, young and old, need in their lives as there are endless possibilities of expressing one’s emotions Introduction Communication is an aspect of life that all people, young and old, need in their lives as there are endless possibilities of expressing one’s emotions and thoughts therefore there are endless possibilities of communicating regardless of whether it is effective or not. Communication can be verbal and by having a verbal conversation with someone or simply using facial expressions, one can trigger a reaction to something that was said or done. People can also use their body language to express their feelings or attitudes such as hunching over which indicates boredom or tiredness. Whether people fight or converse, they will always be communicating and this communication will always effect the interactions between humanity. How people interact with one another depends on a variety of aspects such as; moods, awareness, emotions or voice projections. Sometimes individuals interact by masking their feelings behind their words or by listening to and understanding others whereas others will comment whenever and wherever the opportunity to do so arises. Unfortunately, in our generation, people interact in ways that are influenced by the society in which they live. When living in an urbanized society it is unlikely that an individual will not be influenced by developments such as technology which has become a commodity each individual must have because it makes global networking easier and allows for an increase in multi- tasking and complex learning tasks to be done faster and at a cheaper rates. Although technology has made life easier and more interesting, by means of being able to â€Å"surf the net† and play video games or Nintendo games, it has also limited face-to-face interactions between individuals and made it more ‘acceptable’ for society to express their feelings using emoticons, such as smiley faces, to communicate with others on an ‘emotional’ level. In past generations letters were used to interact and it was considered sophisticated.   Children were taught to play the piano and politely address any individual. Then again they did not have technology to rock their world. Children today use their phones to send messages to their siblings who are just a room away from them. This contributes to the fact that when it comes to direct interactions with people children become withdrawn because they literally don’t know how to converse unless it’s done over a phone . Technology has its advantages but its disadvantages as well but people have managed to do without it. Some individuals have mastered effective communication, where the possibilities of communication range from using fear to get a reaction and/or giving empathy or being brave enough to listen to those they know weren’t initially interested in interacting with them at all. These people acknowledge how and why they feel the way they feel before engaging in any situation they are face with and then react appropriately to get the desired outcome. Many individuals use common sense to analyse others and their surroundings before interacting with them whereas others take it to a whole new level. Individuals use fear to interact but instead they get arrogant smiling. Showing arrogance may get them an elegant reserve or endless expressions of anger or aggression. Some speak uncontrollably and overload others with information they’ll never retain or they talk compulsively get rid of the person. Others blatantly show their lack of interest while others never succeed in getting their point across Communication can always be effective just as the author, Donovon said, â€Å"Real communication is happening, if you feel well and are being understood while you understand† and the possibilities never end Bibliography www.wikipedia.org   Retrieved on Friday the 1st April 2011. www.suite101.com Retrieved on Friday the 1st April 2011.
