Evaluation Criteria Paper Essay Taylor Transit is a company that is growing rapidly. The company must analyze the resources and capabilities of the company to look for the right tools that will provide potential benefits and competitive advantages in human resources. The new approach should include the selection of effective tools that help human resources during the expansion process and the criteria that will be beneficial in the human resource practices. The intent of the paper is discussing the implementation of specific HR tools such as employee selection test, Human Resource Information System (HRIS), successful planning, and the evaluation of the criteria for each tool selection. Human Resource Criteria Identification Identify and establish which is the most appropriate criteria is fundamental because it allows the implementation of new human resources procedures. The following explain the criteria for each of the following tools: Human Resource Information System (HRIS) For Taylor Transit implementation and use of HRIS is of great benefit because it helps to increase the effectiveness of human resources assets as well as provide guidance. The criteria will be based in the necessity of having a good HR information system in where the company will be able to keep information concerning to each employee and any other related HR information such as employees evaluation, disciplinary actions, rewards, and trainings within the organization. The â€Å"HRIS technology supports strategic planning through the generation of labor force supply and demand needs, requirements and forecasts† ( Lippert Swiercz, 2005). This tool will be very useful for the company; given that the company is expanding it is important to have a system that allows Taylor Transit to have a solid database to track data 8,000 employees in order to help in the planning and execution of the company objectives. Selection Test The adequate selection test for the company is important because allow identifying the right candidate since the beginning of recruitment process. The recommended tools for measure the candidates are the cognitive aptitude and the ability tests. â€Å"Cognitive aptitude and ability tests are among the most valid predictors available to organizations† ( Terpstra, 1994). The criteria in the selection of these tools are because the cognitive aptitude test measure the candidate mental capabilities as well their reasoning and communication. On the other hand, the ability test will help to predict the performance of the employee within the company. Besides the background and the experience of the candidate, for the company will be useful make a thorough assessment in order to have the best candidates within the company Succession Planning â€Å"Succession planning must be part of an integrated HR process that includes training, development and performance appraisal† (Stensgaard, 2005). The criteria for choosing this tool is because the â€Å"succession planning also has indirect impacts on measures of firm performance such as productivity and gross returns on assets† (Greer Virick, 2008). This would be excellent tool that would be beneficial in the aid of HR processes (training, development, and performance). One of the things Taylor Transit need to take into consideration is make sure of taking the necessary measures regarding in the proper selection of personnel for each of the positions within the company, as well of having the support of the senior level management. This is important because it allows a systematic process for identifying, evaluating, and developing personnel who are trained to perform key functions within the company. The usefulness of this is essential because it allows certain key personnel receive the necessary tools to develop their skills and abilities, as well as giving them the opportunity in the future to be the future leaders of the company. Conclusion By implementing the right tools allows human resource management to have a higher level of competitiveness. The three selected tools are best suited for the rapid growth of Taylor Transit. Implement the HRIS is helpful because it allows better control of information, and quick access to information for each employee. And for assessing the performance, this will help determine what kind of trainings can be provided to employees. This is helpful because it allows management the assessment and improvement of the procedures of the company. Meanwhile, the employee selection tests are useful because they allow the assessment of cognitive abilities and skills of employees in order to recruit the best possible candidates and may have better performance of the company. This is important because in the long run is cost effective because employees who have better cognitive aptitudes and abilities skills learn quickly, therefore the company does not have to incur in additional expenses for re-training their employees and in turn avoid turnover. Finally, the successful planning is helpful because it allows employees to adapt quickly to the demands of the company; the company in turn may have strategically highly qualified personnel in positions that are key to the success of the company. Implementing these tools allow the proper management of the company.

Melting Performance Enhancement of Triplex Tube Latent

Melting Performance Enhancement of Triplex Tube Latent Melting Performance Enhancement of Triplex Tube Latent Thermal Storage Using Fins-NanoPCM Technique Ammar M. Abdulateef1*, Sohif Mat1, Jasim Abdulateef2 1 Solar Energy Research Institute, University Kebangsaan Malaysia, Bangi, Selangor, Malaysia department of Mechanical Engineering, University of Diyala, 32001 Diyala, Iraq ABSTRACT Latent heat thermal energy storage (LHTES) systems using phase change material (PCM) could have lower heat transfer rates during charging/discharging processes due to its low inherence of the thermal conductivity. In this study, heat transfer enhancement using internal longitudinal fins employing PCM first and nanoPCM secondly in a large triplex tube heat exchanger (TTHX) was investigated by Fluent 15 software numerically. The results showed the thermal conductivity of pure PCM (0.2 W/m.K) could be enhanced to 25% by dispersing 10% alumina (AEO3) as a nanoparticle. However, the melting time is reduced to 12% as compared with the PCM only therefore, a longitudinal fins-nanoPCM technique achieved a complete PCM melting shortly (218 minutes). Consequently, the simulation results have been validated and illustrated a good agreement with the PCM and nanoPCM experimentally. Keywords: phase change material, triplex tube heat exchanger, melting time, longitudinal fins, nanoparticle Introduction The major emphasis associated with most of the solar devices application is the continuous power generation during cloud transients and non ­daylight hours. Thermal energy storage (TES) systems especially the latent heat thermal energy storage (LHTES) systems offer possibility to store higher amounts of thermal energy in comparison with sensible heat thermal energy storage (SHTES) systems. However, most the phase change materials (PCM) that used as storage media in the LHTES systems suffers from the low thermal conductivity (0.2 W/m.K), it often leads to uncompleted melting/solidification process and significant temperatures difference within the PCM, which in some cases can cause a material failure and system overheating. Many researchers studied the different kinds of heat exchangers used in the LHTES systems with (PCM). Among these, concentric cylinder, shell and tube, and triplex tube heat exchanger (TTHX) [1, 2]. Most of these have been proved a high efficient for minimum ISSN: 2367-89921 volume. Agyenim et al. [3] have been presented a significant comparison for three experimental configurations, a concentric tube system with no fins and augmented with circular and longitudinal fins. The system with longitudinal fins gave the most performance with increasing thermal response during charging and reduced sub ­cooling in the melt during discharging. Further, the melting performance enhancement of a small scale TTHX used in LHTES system has received a significant interest by [4, 5] where numerical and experimental investigations have been made using longitudinal fins technique only to improve the melting time of simple PCM. It can be seen, longitudinal fins are most common extended surfaces have been considered in TES systems. In addition, when a triplex tube heat exchanger (TTHX) is used, the heat transfer area is also extended to the PCM and thermal performance is enhanced respect to cylinder or shell and tube heat exchanger. On the other hand, the u nloading latent thermal storage, the solid-liquid interface moves away from the heat transfer surface and the heat flux decreases because of increasing the thermal resistance of the growing layer of the molten/solidified medium. This effect could be reduced by a technique of dispersing high thermal conductivity nanoparticles. The PCM melting dispersed with various volumetric concentrations of alumina (AhO3) that is heated from one side of a square enclosure is investigated numerically [6]. Wang et al. [7] improved thermal properties of paraffin wax by the addition of (TiO2) as a nanoparticle successfully without any surfactant. The biggest challenge that is faced to investigate for both of PCM and nanoPCM was a large triplex tube heat exchanger (TTHX). Therefore, the contribution in the heat transfer rate between the PCM and the HTF are augmented using internal longitudinal fins first and dispersing a high conductivity material such as alumina (Al2O3) secondly to be formed with longitudinal fins as fins-nanoPCM technique to produce the biggest demand thermal energy stored that is required for application in air conditioning systems. Numerical approach Physical model The physical configurations of the TTHX model for two cases (1) pure PCM and (2) nanoPCM are elucidated in Fig. 1. It consists of inner tube, middle tube, and outer tube that have 38.1 mm, 190.5 mm, and 250 mm in radius and 3 mm thickness, respectively with eight internal longitudinal fins each one has 121 mm long and 2 mm thickness. The inner tube and middle tube are made from copper and outer tube from steel. The water is used as HTF to transfer the heat by conviction to the walls and by conduction to the PCM or nanoPCM. The heat transfer during the PCM melting process is based on the both sides heating method where the heat is supplied from both inner and outer tubes during the charging process. The minimum temperature has been required to operate the PCM-LHTES system was approximately 90  °C. The PCM melting numerical model is solved using Ansys Fluent 15 software based on the enthalpy-porosity technique and the finite volume method [8]. The model is drawn and meshed in a two dimensions( r, 9) as well as boundary layers and zone types are defined using ISSN: 2367-89922 International Journal of Theoretical and Applied Mechanics http://www.iaras.org/iaras/journals/ijtam Gambit 2.4.6 software. The grids size number of the numerical model for internal longitudinal fins was calculated to 56200 as illustrated in Fig. 2. Fig. 1. Physical configurations of the TTHX-internal longitudinal fins. Fig. 2. Distribution of the grids size number in the middle tube of TTHX-internal longitudinal fin. Governing equation For the numerical analysis of the thermal process, the following assumptions are made: (1) the melting is Newtonian and incompressible; (2) the flow in the melting process is laminar, unsteady with negligible viscous dissipations; (3) the thermo-physical properties of the HTF and PCM are independent on the temperature; (4) the heat transfer is both of conduction and of convection controlled. The effect of natural convection during the charging process is considered by invoking the Boussinesq approximation that is valid for the density variations of buoyancy force, otherwise the effect is ignored. The density variation is defined as follow: p=Pi/(J3(T-Tl) + 1) (1) Volume 2, 2017 Ammar M. Abdulateef et al. International Journal of Theoretical and Applied Mechanics ttp://www.iaras.org/iaras/journals/ijtam where pi is the PCM density at the melting temperature at Tt and ft is the thermal expansion coefficient. The temperature distribution and viscous incompressible flow are solved by using the Navier-Stokes and thermal energy equations, respectively. The continuity, momentum, and thermal energy equations as follows [9]. The continuity equation: dt(p) + di(pui) = 0(2) The momentum equation: dt(pUi)+ dj(pui uj) = pdjj Ui-dip + pgt + Si(3) The energy equation: dt(ph) + dt(pAH) + di(pui h) = di(kdiT) (4) where p is the density of the PCM, ut is the fluid velocity, p is the dynamic viscosity, p is the pressure, g is the gravity acceleration, k is the thermal conductivity and h is a sensible enthalpy. The sensible enthalpy equation: T h = href + f^CpAT(5) The total enthalpy H equation: H = h +AH(6) where href is the reference enthalpy at the reference temperature Tref, Cp is the specific heat, AH is the latent heat content of thePCM that changes between zero (solid) and L (liquid), y is the liquid fraction, which is generated during the phase change between the solid and liquid state when the temperature is Tt > T > Ts, which can be written as: y = AH/L y = 0 y=l (7) if T T, Y = T-Te if T* Ti-Ts From equation (3) the source term St is: (8) Si = C(l-y) where C(1- y) y3+s 2 ui Y3+ £ (9) is the porosity function U defined by Brent et al. [10]. C is a constant describes how sharply the velocity is reduced to zero when the material solidifies. This constant varies between 104 and 107 (105 is considered), and  £ is a small (0.001) to prevent division by zero. 2.3. Boundary and initial conditions At the initial time, the PCM was in a solid state and the temperature reached to 27 oC. A constant temperature of the tube wall represented the HTF temperature [11, 12] that was at approximately 90  °C.The boundary conditions as follows: Both sides heating method: at r = rt^ T = Thtf(10) at r = rm ^ T = Thtf(11) Initial temperature of the model: at t = 0 ^ T = Tini(12) In case of nanoP CM, we have considere d the same conservation equations, boundary, and initial conditions mentioned above. 2.4.

Validation of an experimental and numerical model Results and discussion Internal fins heat transfer enhancement of PCM melting The isothermal contours of the PCM in TTHX with internal fins at different times (10, 60, 120, and 247 min) are elucidated in Fig. 5. firstly, heat transfer occurred between the hot wall of the tube and solid surface of the PCM by conduction, which dominated the melting process at the early stage and caused a very thin layer of the liquid that is surrounded the longitudinal fin surface and hot wall of the tube while the rest of the PCM remained solid without any phase change because of the effects of natural convection were limited. After 10 minutes, small convection cells are formed between the fins wall and subsequently expanded to the middle tube. Over time, cells convection emerged and facilitated the formation of the large convection cells at 60 minutes that are expanded to the bottom part of tube at 120 minutes because heat transfers by fins. The full PCM melting was accomplished at 247 minutes. Nanoparticle dispersed enhancement The thermo-physical properties of the nanoPCM with various volumetric concentrations of the alumina (AfO3) are calculated using equations (13-17). It is found that, the specific heat and latent heat of the nanoPCM are lower than the pure PCM whereas the thermal conductivity and dynamic viscosity of the nanoPCM are higher than the pure PCM, see Table 2.

Nanoparticle-internal fins technique The isothermal contours of the fins-nanoPCM technique in TTHX at different times (10, 60, 120, and 218 min) are shown in Fig. 7. A significant reduction in time was observed by dispersing 10% nanoparticle to the PCM when the absorbed energy was stored to the required load under the effects of both sides heating method, which is augmented the conduction heat transfer rate. Therefore, the full melting of the PCM is completed at 218 minutes. Consequently, the nanoparticle plays a significant role in the melting rate enhancement where the thermal conductivity of simple PCM (0.2 W/m.K) could be enhanced to 25% significantly that is caused to increase the conduction heat transfer. 10 min60 min 120 min218 min Fig. 7.

The View of Personal Responsibility for Health

The View of Personal Responsibility for Health INTRODUCTION The connection between freedom and responsibility progressed as a topic on healthcare issues for individuals, families, society and environment. It also includes the factors about the functions of healthcare workers and other contributors that affect health, like issues on how to implement government programs, wherein in other settings there is lack of support from the community members. And the question lies on who is to be blamed when health problems arises. People should remain liable for their own choices, and there are identified factors which are outside the human control where in people become sick caused by environmental predicament. And the outcome of these problems at times they put on the faults to society. Despite of the impressive disagreement, there are assertive evidence why this health responsibility has been lowered to the framework of family and society, within the background of political as societal affairs that functions as one of the providers of healthcare in an y setting. The article â€Å"Responsibility for health: Personal, Social and Environmental gave me a question about who are really responsible for our own health? I contemplate all the factors involved, and in my own proposition, we are responsible for our own actions and health consequences. Justifying the case of those people who are physically challenged or mentally incapacitated. On their case support from the community, aside from the family is needed, that is why the government has a fund and program for that sector or member of the community, it is part of the government to provide the necessary steps for them to be back on the right track of healthy living, which cannot be given by themselves, and the healthcare workers will be on their side to perform the health plans for them. But for those who are able and have a clear mind on what is going on, then the decision to have a better health lies on their own hand. It is our own choice for whatever we want in our lives, we are accountable for our own health, we have the agency to exercise whatever judgement we make as our choice for personal health and safety, and we do recognized the bou ndaries wherein our body will be at risk or can still tolerate the elements or substances that, are being advised to consume minimally or avoid completely. And for me the social side, there responsibility is only for us to be warned about the good or bad effects of any substance available, and to provide support in times health concern arises. Its main responsibility for health is to promote and implement programs that can provide optimum health to individuals. Being funded by the government both nationally and locally, its focus mainly to avoid and eliminate potential health risk, and detection of any possible occurrence of any health issues that will affect the individuals and community as a whole. Health funds derived from taxes were used by health government organization. The benefits include in the public health are the free hospitalization within 24 hours emergency and clinic interventions, laboratory test, dental and immunization, and also subsidy for prescribed medicines. The government also provide assurance that health practitioners are registered with them and fully competent in the practice of their profession. Environment can only be responsible when both personal and social fails to perform the responsibilities they should be doing, such as pollution. Hazardous waste materials must be disposed properly and possible health effect or consequences should be eliminated. All programs for the maintenance of clean environment must be strictly implemented and the rule for a clean surroundings must be enjoyable exercised by the people involved. An environmental health issue can only be experienced due to lack of function and concern to health programs, of both individuals and the society itself. Our greatest hope for minimising the burden of preventable disease and death around the world is through Health behaviour change. Tobacco smoking, less active lifestyle, not healthy diet, and alcohol consumption together account for almost one million deaths each year in the United States alone, for example. The World Health Organisation has cautioned that the global scattered of the tobacco widespread could claim one billion lives by the end of this millennium. The rising frequency of childhood corpulence could place the New Zealand at risk of rearing the à ¯Ã‚ ¬Ã‚ rst generation of youngsters to live sickly and die very young than their parents, and the widespread prevalent of fatness among youngsters and mature individuals threatens surprising worldwide health and economic charges. The leading behavioural risks factors are non-compliance to prescribed medical examinations and preclusion and illness management activity, unsafe sex, drug application, family and gun foul play, worksite and motor vehicular accidents) say unequal charges in low-paid jobs and less privileged racial and ethnic populace, as well as in scarce-resource societies all over the globe. Taking these behavioural dangers and distinctions, and the behaviours associated to universal health risks, such as influenza virus outbreak, water scarceness, more harmful ultra violet exposure, and the obligation to guard the health of mother earth itself, will be crucial to global health in this century. There are clinically proven studies for most major behavioural health threats, enclosing tobacco smoking, not healthy diet, unbalanced lifestyle, too much drinking, and diabetes care guidance. There are similar research study instructions for the health care system switches and procedures needed to make sure their efficiency. New society application procedures propose another research study recommendations for a wide array of populace-level, education-, workplace-, and society-based agenda and non-private procedures to develop jab rates and bodily activity requirements for youngsters and mature ones, enhance diabetes self-care guidance, minimise dangerous sun vulnerability, stop second-hand smoke inhalation, eradicate youth tobacco consumption and help mature smokers to quit, minimise workplace and motor vehicular accidents, and reckless drunk driving and family and gun foul play. The restricted power of even our most effective distinct health behaviour precautions, based on studies emphasizing intrapersonal and interpersonal factors of health behaviours, clearly resulted to an exclusive reliance on distinctly oriented precautions would not be enough to reach our critical populace health and health care objectives. These deficiencies led to a basic â€Å"paradigm shift† in our comprehension of what the goals of efficient precautions wanted to be, not just everyone but the full contexts in which they work and live. This movement catalysed the increase of environmental models of health development that have guided the improvement of influential precautions in non-private health and health care facilities. Similar movements in the models and schemes of public health and clinical health advancement opened the way for even wider populace models that link health goals and public health groups, societies, clinical and health care professionals. The Chronic Car e Model proclaimed by the Institute of Medicine and the related structure raised by the World Health Organization as examples. And these structures stimulated works to polish and pertain paradigmatic and principles to interpret efficient clinical and public health programs into application and procedures, enclosing the scattering of innovations model, society and association change principles, and socio-marketing and communications principles. Mega parallel increases in what we have educated about the patterns, procedures and limitations of non-private health improvement and health care quality development from the past three decades describe the basic assumption of this and prior versions of Health Behaviour and Education that an exchange varies between proposition, investigation, and application is crucial to efficient health literacy and advancement. The major principles and examples of health literacy at many levels are: personage, interpersonal, peer groups, society, non-private policy; and in a wide array of settings and populace. Analysis is one of the new exertions to comprehend quickly about â€Å"what generates† by estimating grassroots labours in schools and societies over the nation and the planet to carry out agenda, policies, and ecological shifts to restrain the increase in children obesity as an example as a whole. CONCLUSION: In general, to balance the responsibility between the society and the family, both must recognize its functions to health programs. The society must provide the necessary things for the implementation of care, this involves the healthcare benefits that are subject to be distributed to each member of the society, like medical check-up, free medicine, clean food and drinking water, sanitary project to eliminate pollution, immediate response in any infectious cases, and maintain the ability to identify potential problems. And for the family, the society needs the whole support from each member; the family must participate in all health programs and be open to discuss any health issues. Individual in the family must observe health practice, it includes healthy diet and avoidance of any substances that considered as health risk, and all kinds of vices that affects healthy living. And on the other side of family healthcare protection, it is important that they should acquire health insuran ces for them to be assisted in finances regarding health concerns.

Herbal Phen-fen :: Pills Phen-fen Health Weight Loss Essays

Herbal Phen-fen "Lose All the Weight You Want", "Look Sexy and Feel Great", "Use the Safer Alternative", claim advertisements promoting the use of a recently-created dietary supplement known as herbal phen fen (CompuGraph International ) Created after the original phen fen (phentermine fenfluramine) drug was recalled from the market as a result of serious side effects, including severe heart problems which proved fatal for some consumers, the new herbal phen fen was praised by creators for being "all natural" and lacking any harmful side effects. One who relies strictly on internet advertisements for information concerning herbal phen fen, however, may be seriously misinformed and misled about the true nature of this herbal "cure-all" for weight problems. Articles from various journals and periodicals reveal a darker side of herbal phen fen, illustrating the possible harmful side effects of the pill and explaining the dangers of individual ingredients composing herbal phen fen. Claims of many advert isements for herbal phen fen drectly contradict medical research and scientific studies, raising questions about the effectiveness and safety of the new pill. Popular culture teaches people to search for immediate gratification and quick fix-all methods for every problem, thus fast-working pills appeal to those who don't want to spend months trying to lose weight by exercising and eating healthfully. Advertisers capitalize on this quality of public consumers by appealing to public demands for fast results. "Phen-'Nominal' Results Fast" states one ad on the internet, appropriately titled "Herbal Phen Fast", which boasts the pill's ability to "suppress the formation of fats". The ad, which was produced by the company HealthMatrix, Inc., portrays herbal phen fen as a quick, safe, easy and effective way to control hunger, reduce cravings and ultimately lose weight, yet avoids explaining the side effects of the pill by dismissing symptoms as "few and well-tolerated". The ad names and defines the two primary ingredients of herbal phen fen, St. John's Wort and Mahuang, explaining that the combination of these ingredients leads to weight loss. The ad is designed to appear scientific with the claim that the main ingredient of herbal phen fen, St. John's Wort, "prolongs the reuptake of serotonin in the brain", leading to feelings of personal satisfaction (HealthMatrix, Inc.) The ad provides no evidence, research or case studies for this claim or any other claims. Three quotations by consumers of the pill are included in the ad, but interestingly enough, though the consumers claim feeling "more energetic" and satisfied by smaller portions, none of the quotations actually mention weight loss.

The Problem of Magwitchs return in Great Expectations :: Great Expectations Essays

The Problem of Magwitch's return in Great Expectations It would be fair to say that Australia's role in Great Expectations is fairly minimal. It simply functions as a plot device; a place to deposit Magwitch when he is no longer required and a place for him to return from when needed again to further the plot. With the rise in postcolonial studies, however, Australia and Magwitch's experiences there have become the focal points for new readings of the novel. Thus it is through a postcolonial reading of Great Expectations that the issue of Magwitch's return can be addressed. As I have already pointed out, Dickens uses Australia to get rid of Magwitch in the first place and then to have him return. This return I have always found to be problematic: why does Magwitch come back under the threat of death? The answer 'to see Pip' is not satisfactory. However, a postcolonial reading of the novel, I feel, offers a more plausible explanation. Magwitch's identity and status with regard to the empire throughout the text is an important factor in his motivations for returning. In Postcolonial terms, he is seen through the eyes of the empire (and those of the reader) as other. Pip's first encounter marks him thus, firstly as a convict and then through the cannibal references when he threatens to eat Pip's 'fat cheeks' (3 GE) and threatens to have another convict eat his heart and liver. Due to Magwitch's otherness and subsequent inability to function in normative society, he, along with his heart eating fellow cannibal, is being transported, displaced and removed from the centre. the shipment of convicts to Australia was familiar to Dickens and, though never having gone there, he was a firm believer in its benefits for both the convicts and the imperial centre: it was the 'solution for all social problems for England' (Coral Lansbury, Charles Dickens and his Australia). It seems, for the Victorian reader at least, that no elaboration on Magwitch's Australian life was needed other than that he obtained his freedom and gained financial success for his plans for Pip. This plot development would be entirely plausible and unquestioned by Dickens' readers. A convict could easily better themselves socially as well as financially, particularly under pro-emancipist governor Lachlan Macquarie. And although a class system did exist in Australia, it was less rigid than in England and would have allowed for Magwitch's prosperity.

An Indepth Look at HG Wells :: essays papers

An Indepth Look at HG Wells Herbert George Wells was born on September 21, 1866 in Bromley, England, the last of four children. His mother was a house cleaner and his father was a shopkeeper. When he was eight years old, he broke his leg, spent a lot of time reading, and discovered an intense interest in books. At the age of thirteen, his father was injured in an accident so Wells had to leave school and work for a draper. He hated this work and managed to change his employment by working for his uncle and becoming a part-time tutor. This gave him the opportunity to continue his studies in his free time. He finally won a scholarship to The Normal School of Science in London. He worked as a journalist while continuing his education. In 1891, he married his cousin Isabel. In 1894, he and Isabel were divorced and he then married one of his pupils. In 1895, Wells’ first major work was published- Select Conversations with an Uncle. His next book, The Time Machine, also published in 1895, started Wells on his road to success. This book was followed by The Island of Doctor Moreau, in 1896, The Invisible Man, in 1897, and War of the Worlds, in 1898.[1] H.G. Wells was one of the fathers of modern science fiction. He made his reputation as a writer through what he called â€Å"scientific romances†[2], a comment he made about his own science fiction in the 1930’s. However, he himself said that there were radical differences between his science fiction and that of Jules Verne. Wells said that his own work was â€Å"an exercise of the imagination†,[2] as in The Invisible Man and The War of the Worlds. In these books he was not suggesting a serious possibility, just trying to imagine what might happen in a given situation.[2] Jules Verne, on the other hand, based his stories on scientific knowledge. He criticized Wells as basing his books on fantastic, not scientific, assumptions. Wells in some of his books, however, like The Island of Dr. Moreau, did deal with what he called â€Å"Fantasies of possibilities†.[2] Wells also considered himself a philosophical writer and urged that some of his books be taken seriously.
