Alzheimer essays

Alzheimer essays Alzheimers is the death of the mind before the body. (1) This definition of Alzheimers is very simple, but very true; it sums up the disease in one simple statement. Scientifically Alzheimers is a progressive, neurological disease, in which plaque and tangles, composed primarily of protein, build up on and in neurons respectively, in the hippocampus and interfere with memory, thinking, language skills and behavior. (2) It is still unclear whether these structures cause the disease, or if they are a byproduct of it. The disease is named after a German physician, Dr. Alois Alzheimer. In 1906 he did a case study on a 51-year-old woman who suffered from a brain disorder, and her brain autopsy showed the same plaques and tangles that are used to diagnose Alzheimers today. The cause of Alzheimers is still unknown. (2). However current research is finding that there can be several contributing factors such as genetics, head injuries, age, neuron damage from free radicals, brain inflammation, and environmental factors. Age being the most important risk factor. There are also two types of the disease: sporadic and familial. Familial Alzheimers follows an obvious inheritance pattern, however less than ten percent of Alzheimers cases are familial. If this were the more prevalent form of the disease it would be much easier to predict and therefore one could start preparing far in advance, because this type can strike as early as 30. Scientists have made great advancements on the genetic front of the disease. They have zeroed in on three mutations on chromosomes 1, 14, and 21 that cause early-onset Alzheimers disease, which affects people within the ages of 30-60. They have also found information on late-onset Alzheimers, and other genes they believe increase susceptibility to the disease. There are two general categories of Alzheimers symptoms:...

Change Management Introduction Change Management IntroductionConclusionReferencesRelated Introduction We cannot even endeavor to evaluate and comprehend change management models until we thoroughly understand the meaning of ‘change’.   Even though there is no general definition of change, we would correlate it with words such as alteration, transmutation, metamorphosis, evolution, rejuvenation and modification.  Ã‚   Hughes (2006) has used a generic definition which is â€Å"any alteration in the status quo†. Even far back as 500 BC Heraclius quoted that â€Å"change is constant† it occurs everywhere. It is a defining force in our life, and could be argued that a state of continuous change has almost become routine Luecke (2003). Change is extremely important it will not disappear nor dissipate; it has been studied and researched for many years by different organizations each with the same intention, which is to achieve the ‘perfect’ effective organizational change which will last (Todnem 2005). Some leaders become successful in implementin g change while others fail (Strickland, 1998).   Mourier (1998) reported that failure rates are as high as 60 percent; this is comparable to the 63 percent failure rate for all organizational change reported by Shaffer and Thompson (2002).  Ã‚   Therefore organizations will continue to search for the perfect change literature, which achieves the inevitable (Balogun and Hope Hailey, 2004).   Efficient management of changes at every level is crucial to the success of a Healthcare organization (Todnem 2005). They have been faced with extraordinary changes due to major developments in clinical practice and reorganization within the work place (Upton and Brookes 2000). Due to the various ways in which organizational changes can be managed, we are in need of a standardized model which can be applied to different scenarios. Due to the risks involved, the Healthcare industry needs such universally applicable, efficient change management models now more than ever. In this paper, we dis cuss various change management models and their feasibility in Healthcare. Three important change management theorists: William Bridges stressed on the importance of people in managing change in an organization and stated that the process of change should begin at a personal level (Campbell, 2008). This is vital when working within a staff team as resistance plays a role in the outcome and effectiveness of the change (Paton et al, 2008).   In his seminal work titled Managing transitions, organizational consultant Bridges accurately identifies change and transition as two distinct processes. He describes change as being situational and states that change, does not necessarily involve transition of people (Bridges, 2003).   However, he describes transition as a 3-phase process. The first phase is called Denial where people initially resist the change and express anger, shock and disappointment. The next phase is the Neutral Zone where the reactions of people are less strong and they are ready for the transition at a subconscious level. In the final phase is called the New Beginning, the initial scepticism makes way for hope and enthusiasm and people begin to accept the change with a positive outlook. Bridges (2003) recommends regular interaction and communication with the employees in order to achieve a smooth transition. Being given time to adjust and prepare for the change minimizes resistance (Bernhard and Walsh, 1995). Example given Without implementation Introduction of electronic risk assessment form No training, or enforcing staff of benefits, not   involving them in process Resulted in resistance from staff With implementation Introduction of electronic risk assessment form Excellent training,   staff involved able to understand necessity of new system Resulted in no resistance, letting go of old system, change went smoothly, clinical governance achieved Additionally, he proposes steps such as rewarding the employees contributing to the transition, implementing efficient temporary systems until the transition is complete and setting benchmarks with continuous improvement in order to achieve positive results from the transition. His recommendations have been instrumental in smoothing the process of transition across various Healthcare organizations. However, excluding very simple changes, most changes are multidimensional in nature (Campbell, 2008). Therefore, the change management model has to effectively reach all the impacted areas of the organization. Moreover, various people involved in the change process will have different suggestions and opinions about the cause and the possible results, and changes originating due to external factors such as the economy, recent technological developments are seldom predictable. In such cases, the recommendations of Bridges are not enough. When looking at theorist LaMarsh she proposed a structured change management approach.  LeMarsh (1995) argues that due to the inherent resistance of humans to change, several exceptional ideas and innovative technologies are not adopted and eventually end up being failures. In order to overcome this resistance, she recommends that the people involved in the change process be recognized first. R.Turner, (2003), would agree with this as he recognises the importance that people involved in the change process need to be hightlighted.   Buono (2010) observes that the directed change approach suggested by LaMarsh and R Turner (2003) can cause serious damages if used inappropriately. Due to the unpredictable reactions of the employees who resist the change, organisation members are left to handle emotions such as anger, sadness and loss. Next, since resistance originates from different reasons, (Hargie et al 2004), recommends gathering information about the reasons triggering the resist ance from every level. However, she also accurately predicts a temporary decline in the performance of the organization during the implementation of the change at the same time leading to confusion. Therefore, none of these approaches were sufficient by themselves in handling change management challenges in a healthcare organisation.   However, the most radical development in the field of change management came in the form of Kotter, a Harvard professor. In his best-selling book titled Leading Change (Kotter, 1996), he proposed an eight-step change process (shown below) which marked the beginning of a new era in managing changes. Kotter’s Model described in the box below Step 1  Ã‚   Establish a sense of Urgency Kotter (1996) states that successful implementation of a change requires that a majority of the management wholeheartedly support the idea.   This can be done by creating a sense of urgency, communicating openly, which will de activate resistance.   Once people support the change Kotter states, that this will come automatically. Step 2 Form a powerful collation In order to convince people that change is necessary, a management with strong leadership is necessary.   Build a team of believers by explaining the benefits and inevitability of the change.   Once this is done the change can be implemented.  Ã‚   (Kotter 1996) Step 3 Create a shared vision The best way to get people to support an idea is by convincing them so that their support is voluntary and not forced. Therefore, people who are responsible for implementing and executing the change need to be told about the reasons and the vision behind the change and how it can result in common good.   (Hughes 2006). Step 4 Communicate the Vision If people are to participate in the change process with enthusiasm, they need to be motivated and told about how the change can result in a great future for the organization. This is the most important step of all since this is when resistance will be encountered from various corners of the organization (Day 2007). Step 5  Ã‚   Empower the people to act Since resistance is expected to arise from different levels of the organization.   Change leaders must be prepared to identify the root of the concerns raised and answer them convincingly. This way, all obstacles can be removed in a systematic and effective manner The employees should be allowed to voice opinions and express their concerns. The concerns should not be suppressed since an organisation can grow only if it has motivated and dedicated employees (Day2007). Step 6   Plan for and Create Wins Creating motivation is difficult without showing people rewards, by bringing in a ward system you are rewarding them for good work, or victory.   This will inspire motivation, and gratitude towards the organisation.   Ensuring the change goes even smoother. Step 7   Change improvement check points Kotter (1996) states that â€Å"several changes end up being failures† When looking at change there must not be an end, it is a continual, constant process which should always be checked on, or adapted. To allow the change to last.   As it’s not just time that changes, everything else can. Step 8: Institutionalize new approaches Along with introducing the change, the change leaders must also ensure that the change is incorporated at all levels. It must become the default methodology for all segments of the organization and not just a one-off thing. In order to accomplish this, the change leaders need to clearly explain the employees the relationship between the recent achievements of the organization and the newly adopted practices. By doing this, any change can be sustained irrespective of the initial resistance it encountered. Among the three profound thinkers and approaches discussed above, Bridges and Kotter have been widely discussed due to the effectiveness and versatile of their approaches. Each approach has its share of merits and demerits. While Bridges observes change as a phenomenon, individual level, Kotter attributes an emotional and situational component to the process of change and proposes ways to manage these components in his eight-step approach. Bridges, in his approach, discusses the important steps and concepts involved in the change process (Campbell, 2008). When looking at the reorganisation of shift pattern, let us observe how the approaches of  Bridges, and Kotter would be implemented.   Bridges (2003) and Bernard and Walsh (1996) would gradually implement the change by ending the old shift pattern, ensuring the staff get use to the loss and then implement the new shift pattern. Whilst Kotter at this stage, would create a sense of urgency, reinforce the need for change and communication effectively to all members of the multi disciplinary teams who may cause resistance. The next stage, a major difference exists between the approaches of Bridges (2003) and LaMarsh (1995) and that of Kotter (1996). Bridges and LaMarsh continue to use a top-down, directed change approach where the involvement of the staff is minimal. However, Kotter suggests that the staff be completely involved in the transition. This requires gaining the confidence of the staff by communicating with them and convincing them about the effectiveness of the new shift change. Moreover, Kotter is less severe about the pre-set time line of the transition and stresses more on the successful completion of individual stages in order to ensure the success of the complete transition. Conclusion Healthcare organizations are complex (Day, 2007) due to several interrelated components which interact with each other in an unpredictable manner. Moreover, since the Healthcare industry depends on government funds, economic scenarios too can cause different changes. Therefore, it is important that they have a standard change management model in place so that they can efficiently manage changes as and when they occur. We have discussed the approaches of three profound thinkers who have contributed significantly to the field of change management. While each approach has its share of advantages and disadvantages, the eight-step approach proposed by John Kotter is more feasible in the present scenario.   This is due to the fact that the emotional involvement of employees is crucial for the successful management of a change. Kotters eight-step approach achieves this with the help of transparency and communication. The example of the implementation of shift change proves that in impleme nting a change successfully, Kotters diplomatic approach of allowing the employees and the patients to actively participate in the implementation and allowing them openly voice their opinion proves to be more effective in limiting the resistance.   In this direction, the dominant, bureaucratic approaches of Bridges and LaMarsh fail since the changes are implemented in terms of changing processes and systems. Since these approaches do not care about the effects on people involved, changes are literally forced on the patients and employees. References  ·Ã‚   Balogun, J.

Media Portfolio - Assignment Example The three critical issues in this market present the major pillars of human resource in the country. It is important to note that the Saudi Arabian labor market was not celebrated much in the past due to some unwanted practices including alleged mistreatment of employees. Therefore, during this time that the market in undergoing transformation, revitalization and healing, employee safety and the roles of supervisors in the workplace come in handy. That notwithstanding, saudization is also critical to the healing of this market because of its relation to the replacement of foreign employees in the Saudi Arabian labor market with Saudi nationals especially in the private sector. The Saudi Arabian labor market has not been able to achieve its economic competitiveness in the recent past. This situation has been associated with a number of factors including the most recent being saudization. The employees in this market have also experienced unfavorable working conditions that have deterred them from achieving their maximum potentials at their respective workplaces (Avery, 2005). In addition to that, these employees have not been well motivated to offer their best towards achieving organizational goals and it is for this reason that reports have indicated that Saudi Arabia has been declining in its global economic competitiveness over the last few years. However, there have been efforts to thwart the dangers accompanied by these economic conditions in the labor market. For example, Saudi Arabia has formulated and implemented a number of health, safety and security protocols for its employees in a bid to enhance their motivation and satisfaction and subsequently harness the most out of them. The roles of supervisors, who were previously in the limelight for perpetrating employee frustrations, have been completely overhauled. Saudization can be described as the process

Advertising, Sales Promotion or Public Relations Term Paper

Advertising, Sales Promotion or Public Relations - Term Paper Example It is thus important to examine the interaction of these elements and how a company can make a successful marketing strategy by interconnecting the different elements of promotion and marketing. This paper will analyze the significance of advertising, sales promotion and public relations and their role in allowing companies to achieve their organizational goals. Advertising, Sales Promotion and Public Relations Advertising is understood as different forms of paid promotion and communication strategies for products and services. Sales promotion is a marketing tool that is used to increase sale of goods and services in the short term. While advertising focuses on creating a reason for consumers to make purchases, promotion focuses on creating incentives so that consumers make purchases. The incentives for consumers could be in the form of samples, free trial offers, gift coupons and demonstration of products by company representatives. Sales promotion activities are carried out to attr act new customers, give rewards to current customers or to enhance consumption by infrequent users. Sales promotion uses strategies to target customers that are prone to switch brands and these activities are selected in keeping with the over all marketing objectivities of the firm. The selection process of promotional tools considers competitive responses, budget, target audience and the tool’s objective. ... Advertising, sales promotion and public relations play crucial roles in assisting firms to achieve their marketing goals. Advertising is very important for firms in communicating with customers in different ways. Impersonal communication is done through promotions and point of sale practices while personal communication is done through direct person to person contact. Assuming that a buyer is impacted by four sources of information such as media, sales calls, exhibitions and direct mail, it implies that several people in the firm are engaged in influencing purchases. Sales people are not able to come in contact with all people that impact sales decisions but firms get information from different sources. The buying process is considered to be quite complex as there is a great deal of commercial uncertainty relative to the purchase outcomes. Specifications have to be drawn in regard to characteristics of design and processes relating to operating conditions, size, weight, performance e tc. Potential suppliers will provide product details and evaluation plans, and after trials by the firm, the supplier will be selected. Advertisement Goals The uniqueness of any product is determined by its complexity and the commercial uncertainty relative to its purchase outcome. It was believed for several years that advertising is a simple process whereby the firm simply advertised and customers took note of the message and made decisions accordingly in keeping with their aspirations and needs. However, the process is very exhaustive, in that before any objectives can be set for advertising, the firm has to take decisions about advertising

Understanding Perovskite Film Characterization Routes

Understanding Perovskite Film Characterization Routes Introduction: A perovskite sun illicit chamber is a sort out of daylight based cubicle which consolidates a perovskite cool, calm and collected compound, a good number flask halide-based material, to the same extent the light-social result dynamic layer. Perovskite materials, in favor of instance, methylammonium lead halides are modest in the direction of progress to as a consequence undemanding headed for make. Sun based cubicle efficiencies of strategy with these supplies say unlimited since 3.8% participating in 2009 on the way to 22.1% popular median 2016. The last name perovskite daylight based cell is gotten starting the ABX3 expensive gemstone constitute of the care for materials, because perovskite of structure. Generally, on average careful perovskite safeguard is methylammonium principal trihalide (CH3NH3PbX3, somewhere X is a halogen molecule, used for instance, iodine, bromine before chlorine), plus an optical bandgap inside the constituency of 1.5 plus 2.3 eV depending leading halide content. Formamidinum indication trihalide (H2NCHNH2PbX3) has moreover exhibited ensure, by means of bandgaps in the sphere of the district of 1.5 along with 2.2 eV. The dishonorable bandgap is earlier toward the tighten up used for a separate than methylammonium lead trihalide, therefore it be supposed to transpire all set instead of upper efficiencies. The basic waste going on perovskite daylight based device was popular a shading file sect via CsSnI3.. A dull worry is the fuse of direct such as a bit of the perovskite materials; sun based cells during tin-based perovskite shields, on behalf of instance, CH3NH3SnI3 experience moreover been represented in the company of hand down restriction adjust efficiencies . Diagrams demonstrates the energy exchange efficiencies of the perovskite-primarily based devices over late years apparently with emanant photovoltaic research improvement and besides traditional thin film photovoltaics. Figure 1: Perovskite sunlight hours primarily based cells have extended in strength alternate adequacy at a remarkable rate diverged from various sorts of photovoltaics Perovskites are a group of resources with the purpose of stake a nearly like structure, which operate a crowd of brisk properties in the manner of superconductivity, magnetoresistance with the sky is the ultimate beginning so as to point. These adequately together supplies are seen equally the luck of daylight based cells, since their explicit put together makes them refine on behalf of engaging insignificant exertion, profitable photovoltaics. Figure 2: Pervoskite. a making slight film PV class is being enclosed, in like path named third period PVs, which proposes PVs utilizing advances that can conquer current ampleness and execution limits or depend on upon novel materials. This third moment of PVs wires DSSC, ordinary photovoltaic (OPV), quantum bit (QD) PV and perovskite PV. A perovskite sun situated cell is some sort of daylight based cell which fuses a perovskite sorted out compound, most for probably the most part a cross regular inorganic lead or tin halide-based material, as the light-gathering dynamic layer. Perovskite materials, for example, methylammonium lead halides are humble to produce and large an easy task to manufacture. Perovskites have inalienable properties like wide maintenance territory, brisk charge parcel, long transport detachment of electrons and openings, long transporter division lifetime, which make them to a good degree empowering materials for solid state sun situated cells. Perovskite sun based totally cells desire to construct the performance and lower the value of solar based essentialness. Perovskite PVs for beyond any doubt keep ensure for excessive efficiencies,.A noteworthy favored point of view perovskite PVs has over preferred solar located advancement is they can react to various precise wavelengths of mild, which allows them to exchange over a more outstanding measure of the light that receives in touch with them into power. Likewise, they offer flexibility, semi-straightforwardness, specifically fitted part elements, light-weight and that is currently the start. Regularly, gadget originators and researchers are positive that such residences will open up numerous extra packages for sun arranged cells. One difficulty is their preferred price , and every other is that much less expensive perovskite sunlight hours based cells have a quick future. Perovskite PVs furthermore smash down rapidly internal seeing wetness and the ruin matters strike steel anodes. Overpowering exemplification to assure perovskite can upload to the cellphone price and weight. Scaling up is every other problem high performance opinions were proficient the use of little cells, that is great for lab trying out, but too little to possibly be used as a bit of a real sun based board. An vital problem is dangerous fine a substance known as PbI is one of the breakdown after effects of perovskite. This is thought to be poisonous and there are stresses that it can be disease bringing on .In like manner, numerous perovskite cells use lead, an significant tainting. Examiners are consistently attempting to find substitutions, and feature officially made working cells the use of tin. Perovskite Fabrication: The structure beneath addresses a wellknown (non-adjusted) perovskite sun arranged cell primarily based upon a preferred glass/ITO substrates with metallic again contact. All this is required to shape a operating device from the perovskite are two rate-specific. An significant range of the usual interface layers from the universe of normal photovoltaics work for the most part nicely. For example, PEDOT:PSS and the PTAA-class of polymers ability wonderfully as starting interface layers, while PCBM, C60, ZnO and TiO2 makes convincing electron interfaces. Regardless, the sector is new to the point that there is a boundless record of possible interface substances to be researched. Figure 3: structure of perovskite sunlight based cell. 2. Characterization of Perovskite: Material characterization settle for a basic half in power phenomenon (PV) analyze and is essential understand the extensiveness of latest improvements . Several systems from particles to teams ar beginning at currently accessible to decide on the structure and properties of PV materials, structures and devices. To understand remuneration by native flaws or probably accidental wrecking influences, and in the instance of crystalline materials, grain limit imperfections and prompts comprehension of real cell efficiencies. The final characterization are often achieved simply with a blend of new portrayal ways to incorporate the basic method of characterization. There are several characterization of perovskite solar cell such as XRD, SEM ,AFM ,KPFM ,Photo Celiv, impedance ,XPS/UPS and UV -VIS . 2.1. X-RAY DIFFRACTION (XRD) Beginning at currently high ability skinny film electrical happening sun organized cells tools square measure being created in assortment of crystallographic outlines: epitaxial, crystalline, transparent or imprecise. Essential and microstructural parameters of those devices square check notably linked to the execution of the sunshine burning cell. Considering the broad extent of materials and structures used as somewhat of creating the sun care managed cells there rectangular measure a broad group of x-shaft optical trend and dispersing methodology and geometries which will be used for depiction of sun handled cell device. XRD is associate degree in a situation non-perilous examination mechanical assemblage that offers quantitative data on the crystalline periods in thin-film structures. Which has a smart alternative of X-bar supply and optical real mathematics, XRD examination can be related to a diverse assortment of crystalline and crystalline materials used for PV. precisely once used as a chunk of conjunction with compound assessments, a separated depiction of thin-film structures will be delivered. XRD strategies count on after the dispersing of X-pillars by the particles in an exceedingly discontinuous bunch, i. e., the cross-punch phase. wise diffusive happens once the stage separate between the scattered surf from particles within the cross-space planes is actually a varied of 2, an ailment thats geometrically met when the method length qualification of the scattered waves is surely an elementary number of wavelengths. The lure is finding the illustration and discoverer at positions in house w ith reference to the scene column so optic phenomenon maxima will be distinguished. totally different agreements, for example, the turning valuable stone system, the Laue procedure and then the powder methodology block measure comprehensively used for crystallographic analysis. assortments of the powder system square measure utilized, having a powder or film illustration lying digressively to a concentrating drift represented by the partition between the X-pillar supply emanant difference and therefore the circumstance during this procedure, an control most outrageous within the diffracted surface is found when the affiliation between the picture . The example is lighted with a lightweight emission x-beams on the variable goal extend. Association within the specimen brings regarding diffracted x-beams once the Bragg condition is consummated. occurring spectra area unit traditional for man-made piece and stage. The procedure terribly provides level ID (e. g. co2 ), on-board stage measuring, the troubles crystallinity, crystal size and building block estimate. To get superimposed materials, Grazing Occurrence XRD (GIXRD) permits integrative profundity identification of phases within the structure. Non-damaging examination with characteristic proof of stage e. g. quartz/cristobalite/tridymite for silicon dioxide Stage analysis, the troubles crystallinity and estimation of crystal and building wedge live Profundity identification of integrative and stage changes within superimposed materials by Grazing Incidence XRD Estimation of layer thickness on the nm scale for really clean materials utilizing Ray x Reflectivity (XRR) The cause for this review is to look at impact of grouping doping at variable molar proportion of I, Cl, and Br in inorganic-herbal sun based basically cells utilising CH3NH3PbI3xyBrxCly perovskite mixes. The impact of incredibly stay of grouping doping of I, Cl and Br mixes in the perovskite shape on the electrical phenomenon conduct are going to be tested for boosting the electronic transporting conduct.

Impact of the Automobile from 1900-1945 :: American America History

Impact of the Automobile from 1900-1945 The impact of the automobile between 1900 through 1945 was immense. It paved the way for a future dependency on the automobile. To paint a better picture, imagine life without an automobile. Everyday life would be dull, cumbersome, and tedious. An individual's mobility would be very limited. Basically, the life without an automobile could not be fathomed. The importance of the automobile is often taken for granite. Society may not know what appreciate the impact of the automobile and effects it has created. The impact of the automobile had both positive and negative effects on America between 1900 through 1945. Automobile provided an outlet for individuals and spread the freedom of travel among all classes of people. It also helped to introduce rural dwellers to the aspects of urban life and vice versa. One of the negative effects was that automobiles helped to put of big decline in the use of railroads. Over the course of the paper, I will try to expose the huge impact of the automo bile an early twentieth century life. The image of a self-propelled vehicle dates back around the early thirteenth century. Europe is the birthplace of the automobile, but it was adopted by America. Roger Bacon had a vision of cars being made without animals so they can be at astonishing speeds and maneuverability . About three hundreds years later, Leonardo Da Vinci rejuvenate Bacon's idea with hopes of creating a military vehicle. His idea was transformed into the modern day tank. The first step in making a self-propelled vehicle was taken by Nicholas Joseph Cugnot. He was an eighteenth century French artillery officer. "In 1769 he built and ran a three-wheeled carriage mounting a steam engine of his own design, with the idea that it might be used for pulling guns"2. It was very clumsy vehicle that was shot into the air when it reached the top speed of three miles an hour. Cugnot's vehicle provided almost no improvement of the horse. In the early years of the nineteenth century an American and British duo had began an automotive experiment. Richard Trevithick, a British engineer, and American genius, Oliver Evans created a workable but crude vehicle propelled by steam3. This early experiment was an improvement, but the railroads and stagecoach companies joined together. With this new combining of forces the new steam vehicle, the Orkuter Amphibolos, was brought down.

Internet regulation, Government Intervention of the Internet

Internet regulation, Government Intervention of the Internet During the past decade, our society has become based solely on the ability to move large amounts of information across large distances quickly. Computerization has influenced everyone's life. The natural evolution of computers and this need for ultra-fast communications has caused a global network of interconnected computers to develop. This global net allows a person to send E-mail across the world in mere fractions of a second, and enables even the common person to access information world-wide. With advances such as software that allows users with a sound card to use the Internet as a carrier for long distance voice calls and video conferencing, this network is key to the future of the knowledge society. At present, this net is the epitome of the first amendment: free speech. It is a place where people can speaktheir mind without being reprimanded for what they say, or how they choose to say it.American Civil Liberties UnionThe key to the world-wide success of the Internet is its protection of free speech, not only in America, but in other countries where free speech is not protected by a constitution. To be found on the Internet is a huge collection of obscene graphics, Anarchists' cookbooks and countless other things that offend some people. With over 30 million Internet users in the U.S. alone (only 3 million of which surf the net from home), everything is bound to offend someone. The newest wave of laws floating through law making bodies around the world threatens to stifle this area of spontaneity. Recently, Congress has been considering passing laws that will make it a crime punishable by jail to send 'vulgar' language over the net, and to export encryption software. No matter how small, any attempt at government intervention in the Internet will stifle the greatest communication innovation of...

Diary Entries Essay Example | Topics and Well Written Essays - 750 words

Diary Entries - Essay Example I continue thinking about my psychiatrist, which is even after he denies the fact that I need one. I contend that the psychiatrist wants to find out the reason why I hike in the forests, while collecting butterflies and watching birds and I intend to show my collection to him one (Bradbury, 23). Most of what I do is considered as strange by other people even when, for my time, it seems normal. That I need a psychiatrist is crazy, particularly since I do the same things that other people do. I ask Montag concerning his firefighting job, stating that he is very different from other firefighters I know because he is attentive to what I tell him, and actually, tries them out. I go on to tell him that he is one of the few persons who stand (Bradbury, 23). It seems that most of the people that I am in contact with are always fast paced, and Montag is no different. I think that Montag does not have time to notice the dew that had settled on the grass in the morning. For instance, it is up t o me to tell him that there is dew on the grass that morning and every morning. Suddenly, I notice that he does not seem to remember whether he had ever noticed the dew and this makes him very irritable. I have always noticed most small things that others cannot, which makes me very observant. After I pester Montag with various questions, he surprises me by telling me that I had better run on to the (Bradbury, 24). I obey him, and see him tilt his head back into the rain, open his mouth for a few minutes, and catch the falling drops of rain just as I had been doing when they met. I also notice that Montag seems curious regarding the things that I am doing because he is always attempting to do the things that I ask him to do. Diary entry #2: Montag I meet Clarisse McClellan, who is my new and vivacious young neighbor and I just seem to begin questioning whether I am happy. She gives me enlightenment, as she asks me questions on my own individual happiness, as well as his occupation a nd the fact that I do not seem to know much concerning history (Bloom 16). Clarisse, through the little things she does, also gives the opportunity for me to see dramatic changes within the government regarding the perception of citizens about their history. For instance, I had no idea that the real work of firefighters entailed fighting to put off real fire, or even that billboards only stand at twenty feet in height. In addition, I also had no idea that people had the ability to actually speak to each other. This is because the use of parlor walls by the government had removed any requirement for causal conversation (Bloom 16). Clarisse arouses the curiosity in me as she begins to aid me in the discovery of the fact that I have been missing real happiness in my life for a long time. After I meet the young girl Clarisse, I go back to the house and find that my wife is lying on the bed, unconscious. She has her Seashell radios close to her head and I find that she has overdosed on s leeping pills, as well as tranquilizers (Bloom 18). Her life is saved after two technicians, who I find very impersonal; bring machines that aid then in removing the drugs from her belly, while also giving her a complete transfusion. However, I believe that it is possible she will overdose again with no knowledge of what she was doing. While it is my wish to discuss the overdose,

Assignment (Economics) Example | Topics and Well Written Essays - 500 words - 2

(Economics) - Assignment Example This is mainly because of overcrowding in the factory or when addition of extra labor results in over utilization of capital resources. Diseconomies of scale are observed when a firm becomes a large scale business but loses control over its cost structure, thereby resulting in high costs per unit. Management inefficiencies, poor communication and absence of motivated workers lead to decline in productivity and subsequently in diseconomies of scale. The average cost decreases as the quantity produced increases because the contribution of fixed costs to each unit decreases. For instance, the fixed costs remain same no matter what the quantity produced is; therefore, if more units are produced the total costs become low that then result in low average total costs. Assuming both firms have similar fixed costs, then the firm XYZ will have higher cost per kilowatt hour because its total output is three times below the output of ABC. For instance, the contribution of fixed costs in average cost per kilowatt hour will be higher in case of firm XYZ due to low productivity. Explicit costs are those that are incurred during business operations i-e producing and offering goods and services. Indeed, they lead to cash outflows. Implicit costs, in contrast, are the opportunity costs of using business resources / assets that could or could not be calculated in monetary terms. Total fixed costs remains same or unaffected as output rises in the short run, assuming no change in capital resources. However, if firm expands in the long run and rents a large building for office, factory or other business purposes, then its fixed costs will also be changed. If a flawless / impeccable car is built by a single highly specialized individual then I could pay what that car-manufacturing firm or individual person demands for that car because the utility that I would get from using that vehicle would
