Syftet med studien var att undersöka samband mellan personlighetsdimensioner och upplevd stress på arbetsplatser utifrån fem-faktormodellen samt krav-kontrollmodellen. 128 deltagare deltog i enkätundersökningen; 58 män och 66 kvinnor mellan åldern 20-69 år. Studien var en tvärsnittsstudie med självskattningsfrågor och urvalet gjordes genom ett bekvämlighetsurval. Enkäterna besvarades på arbetsplatser i Örebro, Eskilstuna, Västerås och Stockholm. Tidigare forskning påvisar samband mellan personlighet och stress, men få undersöker detta utifrån krav-kontroll-stödmodellen. Föreliggande studie undersöker detta utifrån graden av krav och kontroll. T-test visade skillnader utifrån kön, envägs ANOVA visade skillnader i yrkestitel och ålder. Korrelationsanalyser visade positivt samband mellan krav och upplevd stress samt negativt samband mellan kontroll och upplevd stress. Resultatet visade positivt samband mellan agreeableness, openness, conscientiousness och krav samt positivt samband mellan openness och kontroll. / The purpose of the study was to examine correlations between personality traits and perceived stress at work places based upon the Five Factor model and demand-control model. 128 participants attended; 58 men and 66 women aged 20-69 years. The study was cross-sectional with self-report measures and convenience sampling. Surveys were answered at work places in Örebro, Eskilstuna, Västerås and Stockholm.

ABSTRACT Title: The Internet and Marketing: A case study of SmartGuy AB. and PostNord AB. Level: D-Level Final Master Thesis in Business Administration Authors: Naa A. Allotey and Ashenafi T. Degefie Supervisor: Professor Akmal Hyder Date: 2013 June Aim: Technology has changed the way businesses are being done specifically in the internet marketing. Even though the growth & development of internet marketing is rapid, many new firms doing e-business are increasing. To make use of this ever increasing opportunity many companies without adequate knowledge and lack of concepts about internet marketing enter into this business that leads into failure. This study examines how businesses use the internet as an effective marketing tool in order to increase business efficiency and survive in the competitive business. The study also identifies the various problems that are affecting the internet marketing business and review possible strategies. Method: The study adopted a qualitative method through a deductive approach. Research questions were developed to gather the data. A semi structured interview was conducted with personnel from Nordpost and SmartGuy. The data was analysed and linked with the theory to provide answers to the research questions. To enhance the richness of the study secondary data sources has been employed in a form of scientific articles, literature, annual reports from the case companies and online sources.  Results and Conclusions: The result of this study shows that the rapid development of online marketing makes it imperative for businesses to seriously consider the internet as a marketing tool in order to remain competitive. There is no specific strategy to adopt but firms could develop internet marketing strategies depending on the nature of their business in order to cope up with the ever changing environment. It also identified the difficulties traditional marketers face when integrating internet marketing. The conclusion is that businesses can overcome the barriers affecting Internet marketing if they take time to identify their micro and macro environments and adopt appropriate strategies. Suggestions for future research: Although this study identified that there are some factors affecting the internet marketing and suggested key elements in developing e-marketing strategy, the results of this study and conclusion, to some extent have some limitations.  Firstly there are only two case companies investigated which makes it hard to generalize the outcomes. Secondly, current literatures in the area of study were very limited showing that researchers are not really giving time to this all important topic.  Thus future research could look more into this subject area, broaden the scope of the investigation to more companies and could also concentrate in the areas where there is a need for a unique strategy development for different internet companies. Future researchers could also look at how the transition from traditional to internet marketing could be made very simple. Contribution of the thesis: The study provides significant insights into the factors affecting internet marketing and e-business strategies that can be adopted to make it an effective marketing tool, a topic often overlooked by published material. Even though there are no specific e-marketing strategies to directly copy or implement, the study suggests specific areas a business should take into consideration while developing the strategy. For businesses, the question of using the internet as a marketing tool should be one of ‘when, why and how’. A well-structured and well thought out business plan which is still applicable is the backbone of any company who is going to be successful in the e-commerce industry.

In the present PhD work, three sophisticated models based on the "Engineering" modeling approach have been utilized to conveniently describe and thoroughly analyze details of Lightning events at the CN Tower. Both the CN Tower and the Lightning Channel are represented by a number of connected in series Transmission Line sections in order to account for the variations in the shape of the tower and for plasma processes that take place within the Lightning Channel. A sum of two Heidler functions is used to describe the "uncontaminated" Return Stroke current, which is injected at the attachment point between the CN Tower and the Lightning Channel. Reflections and refractions at all points of mismatched impedances are considered until their contribution becomes less than 1% of the originally injected current wave. In the proposed models, the problem with the current discontinuity at the Lightning Channel front, commonly taken care of by introducing a "turn-on" term when computing radiation fields, is uniquely treated by introducing reflected and transmitted components. For the first time, variable speed of propagation of the Return Stroke current front has been considered and its influence upon the predicted current distributions along the whole Lightning Channel path and upon the radiated distant fields analyzed. Furthermore, as another novelty, computation of the electromagnetic field is accomplished in Cartesian Coordinates. This fact permits to relax the requirement on the verticality of the Lightning Channel, normally imposed in Cylindrical Coordinates. Therefore, it becomes possible to study without difficulty the influence of a slanted Lightning Channel upon the surrounding electromagnetic field. Since the proposed sophisticated Five-Section Model has the capability to represent very closely the structure of the CN Tower and to emulate faithfully the shape of, as well as physical processes within the Lightning Channel, it is believed to have the potential of truthfully reproducing observed fields. The developed modeling approach can be easily adapted to study the anticipated radiated fields at tall structures even before construction.

Five-axis CNC milling machine tools bring great facility to produce complex workpieces with increased dimensional accuracy and better surface quality in shorter machining times. However, kinematics of five-axis machine tools has a complex form which makes it difficult to operate these machine tools properly. The difficulty arises from the complexity of NC-Code generation and tool path verification. Collision of machine tool or setup components with each other is a severe problem in five-axis machining operations and usually results from inadequate postprocessors or insufficient collision checking due to absence of well-prepared simulation and verification programs. Five-axis CNC machine tool owners may get rid of this problem by purchasing commercial postprocessors, simulation and verification programs. However, these programs are expensive and small and medium enterprises (SME&rsquo / s) usually cannot afford the costs of these programs. In the related libraries of commercial programs, there is great number of CNC machine tools, which is generally unnecessary for SME&rsquo / s. An alternative to overcome this problem is to develop particular program, which is capable of postprocessing, simulating and verifying milling operations, for each certain five-axis CNC machine tool. In this study, a software named &ldquo / Manus 1.0&rdquo / , which performs postprocessing and simulation processes, has been developed for the high speed &ldquo / Mazak Variaxis 630-5X&rdquo / CNC five-axis machine tool, located in METU-BILTIR Center. Moreover, tool path verification algorithms have been developed to detect collisions. The software has been written in Borland C++ Builder5.0. The developed program has been tested in sample milling operations and satisfactory results have been achieved.

This exegesis examines the landscape of heaven depicted in the contemporary novel, The Lovely Bones by Alice Sebold. I examine the various characteristics of the heaven (or 'afterlife') depicted in Sebold's novel, with the aim of ascertaining the narrative effects of using this device. Using Ingrid Daemmrich's analysis of the paradisiacal motif in literature as a framework (Daemmrich, I 1997, Studies on Themes and Motifs in Literature: Enigmatic Bliss, The Paradise Motif in Literature, Peter Lang, New York), I reveal characteristics in The Lovely Bones that are both consistent with and challenge traditional literary representations of heaven and which therefore demonstrate that the text utilises the established literary motif of heaven for symbolism and meaning, but in a contemporary context. I explore the growing trend of contemporary literary heavens by reviewing two other literary heavens that are relevant to this scholarship. I examine where as writers and readers, we ascertain our concept of heaven (in society's religious foundations and from prior literature), and for the relevance of the key text, I briefly discuss the author's likely cultural influences. Having established the novel's lack of alignment with a religious version of heaven, I then examine the nature of and the narrative effect of, the personalised heaven depicted in the novel, The Lovely Bones. In doing so, I explore one of the new portraits of heaven in literature, an example which represents a growing trend away from portraying a classic edenic heaven shared by all humanity (and traditional to literary representations of heaven), toward a contemporary, personalised heaven that seeks to meet the wants and desires of the individual in our modern society. With reference to literature's ability to reflect back to us, our society's beliefs and values, I examine what this new portrait of heaven reveals about society. Access to the project examined in conjunction with this exegesis has been restricted due to copyright.

Apresenta-se neste trabalho uma plataforma de simulação, acionamento e controle de máquinas de indução trifásicas e pentafásicas, baseada na integração entre ambientes de simulação e de prototipação em tempo real.

Inicialmente é abordada a teoria que envolve o acionamento e o controle de máquinas de indução. Descrevem-se os modelos da máquina de indução trifásica e da máquina de indução pentafásica, o segundo incluindo efeitos de terceiro harmônico do campo do entreferro. Também são abordados os modelos de inversores de frequência e as técnicas, escalar V=f e vetorial por orientação indireta e direta de campo, de controle de máquinas de indução. Depois disso, são descritas as ferramentas de software desenvolvidas e também a plataforma de hardware utilizada. As ferramentas de simulação implementadas são validadas para permitir a reprodução da dinâmica das máquinas de indução, dos blocos sensores de corrente, velocidade e torque e do acionamento de potência. Além disso, são desenvolvidas ferramentas de controle que implementam as técnicas de controle V=f e orientação de campo, também incluindo blocos que implementam estimadores de fluxo, transformação de coordenadas e de referencial, entre outros. A integração entre o ambiente de simulação e a prototipação do algoritmo de controle é obtida por meio do uso do framework da plataforma dSPACE DS1104 e da implementação de ferramentas de tempo real que servem de link entre ambiente de simulação e de prototipação. Do ponto de vista do usuário da biblioteca proposta, a transição entre ambiente de simulação e de prototipação é realizada pela substituição de blocos de modelos por blocos de tempo real. O algoritmo de controle pode ser simulado em ambiente Simulink e diretamente compilado a partir deste para a plataforma dSPACE DS1104, onde será executado em tempo real. São criados experimentos que demonstram a aplicabilidade da plataforma proposta por meio da implementação em simulação e também em tempo real de controladores de velocidade para a máquina de indução trifásica e para a máquina de indução pentafásica. Utilizam-se as técnicas de controle escalar V=f e controle vetorial por orientação direta e indireta de campo. / In this work is presented a platform for simulation and prototyping of control techniques for 3-phase and 5-phase induction machines. It is developed a toolbox library in MATLAB/Simulink R to be used with dSPACE R DS1104 platform. The software tools and the hardware platform are both described and provide an integrated environment which allows the user to develop and evaluate control techniques for induction machines by means of pure simulation as well as executing them on an underlying hardware platform connected to the machine. The transition from simulation to a hardware platform is done transparently for the user using rapid prototyping tools. Firstly it is presented the induction machine control theory. The model for the 3- phase induction machine is described, as well as the model for the 5-phase machine. The model for the 5-phase induction machine allows the inclusion of the effects of the third harmonic of the air-gap field. The models for the power inverters with 3 and 5 phases are also described and the theory of the V=f control together with the theory of field oriented control are detailed. The developed software tools for simulation, control and real time execution of control techniques are explained in details and the hardware implementation for signals instrumentation are also presented. The integration between software simulation and real time execution is achieved by means of the use of the dSPACE R DS1104 framework together with the real time tools developed in MATLAB R . From the user point-of-view, the transition from simulation environment to real time execution environment is achieved by simply changing the model blocks by the real time blocks, both developed in the proposed framework library. The real time environment can be compiled inside Simulink and the algorithm can be loaded into DS1104 board to be executed. Experiments that demonstrate the applicability of the proposed framework are presented which implement the V=f, indirect field oriented and direct field oriented controls on both, 3-phase and 5-phase, induction machines.

Este trabalho contempla o projeto de um manipulador robótico cilindro atuado por motores de passo com cinco juntas de atuação. As etapas do projeto do robô, que tratam este estudo, foram divididas em: projeto mecânico; modelagem matemática; projeto do controlador; e simulações. O projeto mecânico apresenta uma proposta de configuração e dimensionamento mecânicos que supre a demanda exigida para a operação analisada. O modelo matemático apresenta as características elétricas e mecânicas do atuador e as características mecânicas do robô. O projeto de um controlador linear é realizado por meio da alocação dos polos do sistema em malha fechada através da realimentação dos estados de posição e de velocidade angulares do rotor unidos a um integrador do erro de posição angular. Para o primeiro grau de liberdade, por conta da variação do momento de inércia de massa associado a essa junta, um controlador com ganhos parametrizados foi projetado, no qual os ganhos são calculados baseado no modelo matemático relativo ao momento de inércia de massa associado a essa junta. Por meio de simulações computacionais, avaliou-se o projeto dos controladores no movimento ponto a ponto dos cinco eixos de atuação e a variação do momento de inércia de massa sobre a primeira junta. Os resultados dessas simulações mostraram que os controladores propostos cumprem com a dinâmica desejada nos cinco graus de liberdade do robô. / This work contemplates the design of a robotic manipulator, which is operated by a stepper motor with five actuation joints. The robot design steps were divided into: mechanical design; mathematical modeling; controller design; and simulations. The mechanical design presents a proposal of mechanical configuration and sizing that supplies the required demand for the analyzed operation. The mathematical model presents the electrical and mechanical characteristics of the actuator and the mechanical characteristics of the robot. The design of a linear controller is accomplished by allocating the poles of the closed loop system by states feedback of the position and angular speed of the rotor attached to an angular position error integrator. For the first degree of freedom, due to the variation of mass moment of inertia associated with this joint, a controller with parameterized gains was projected, in which the gains are calculated based on the mathematical model related to the mass moment of inertia associated to this joint. By means of computational simulations, we evaluated the design of the controllers in the point-to-point movement of the five actuation joints and the variation of the mass moment of inertia on the first joint. The results of these simulations showed that the proposed controllers comply with the desired dynamics in the robot’s five degrees of freedom.

Three-dimensionally woven composites are a relatively new class of material that offer improved out-of-plane performance by including through-the-thickness mechanical reinforcement compared to traditional laminated composite structures. The mechanical properties are highly dependent upon the weave architecture as this dictates the nature of the through the thickness reinforcement and its effect in improving out-of-plane shear strength. A comparison of two testing methods, Short Beam Strength, and Five Point Bending was conducted over a range of span to thickness ratios with the latter found to be more consistent at producing shear failure over a greater range of span to thickness ratios, although evidence of matrix crushing was present in both, and flexural failure in the Short Beam Strength test. Two weave architectures, the orthogonal and angle weave were subjected to the Five Point Bending test and the failure and damage progression behaviour of both weave architectures were characterised using Digital Image Correlation analysis to measure the edge strain through the thickness of the specimens. This testing showed the angle weave architecture had in general a higher failure strength, and more gradual failure due to longer debonding cracks. The orthogonal weave architecture showed a characteristic post-failure response indicative of crack bridging with discrete load recovery and load drop phases. A numerical model developed from previous work builds on the mosaic modelling method and was modified to include cohesive elements in order to simulate interface debonding via the maximum stress criterion. The simulations are consistently 15 20% greater in failure loads, and 8 - 12% greater in failure shear stresses than those found from the averaged experimental results over the range of tested span to thickness ratios. Post failure response was not modelled. The work presented in this thesis is another step towards gaining a thorough understanding of the mechanical properties of 3D woven composite structures, focussing in particular on out of plane shear strength. The modified mosaic modelling method used showed it is effective at modelling the out of plane testing of orthogonal 3D woven composite structures, and offer the potential to predict the failure of larger composite structures of the same construction and 3D woven architecture although developments are still needed in modelling the post failure response.

This paper investigates the impact of social norms on the performance and valuation of “controversial stocks”- publicly traded companies involved in the production of Adult Entertainment, Alcohol, Gambling, Nuclear Energy, Tobacco, Uranium, and Weapons. Their performance and valuation is directly compared with compare non-controversial stocks. The paper consider an international sample of 941 controversial stocks. Employing a multi-factor performance measure, seven countries provide a significant outperformance of controversial stocks across all relevant control factors. The valuation analysis, however, provide mixed results on a country level, but on the global market-to-book ratio provide a significant overvaluation of controversial stocks compared to comparable non-controversial stocks, which contradicts the prediction of an undervaluation.JEL classification:
