Full textAbstract:
Soil tillage is one of the most important agrotechnological processes having huge influence on the sowing, germination, growing, yield and quality of cultivated plants. At the same time soil tillage is one of the most expensive and energy consuming agrotechnological processes of plant cultivation. The conventional tillage technologies using mouldboard and intensive cultivation machinery have both a positive impact on the preparation of the seedbed for plants and a negative impact as they are rather detrimental to the environment, soil, its properties, biodiversity, pollution of water bodies, etc. During the conventional soil tillage the crop residues of the last yield are incorporated into the deeper layers of the soil and the soil surface is not covered. Such soils are much susceptible to the environmental forces and are easier disturbed by wind and water erosion. Every year around 6 mio ha of fertile soil areas are lost due to inappropriate agricultural activities and changing environmental conditions. Another very important factor is that deep ploughing is an unproductive soil tillage method pertaining to huge time and energy consumption. At the same time multiplex driving of heavy weight agricultural machinery over the soil results in negative influence on its peoperties as well as consuming of huge amounts of diesel fuel results in high pollution of the environment with the greenhouse gas. Therefore, in order to reduce the negative influence of agricultural activities...

Tuo pačiu žemės dirbimas yra ir vienas iš brangiausių ir energijai imliausių kultūrinių augalų auginimo agrotechnologinių procesų. Įprastinio žemės dirbimo technologijos, kuriose naudojamos verstuvinės ir intensyviai dirvą purenantys žemės dirbimo agregatai, greta teigiamo poveikio augalų sėklų guoliavietės paruošimui, yra pakankamai žalingos aplinkai, dirvai, jos savybėms, biologinei įvairovei, vandens telkinių taršai ir t.t. Įprastinio žemės dirbimo metu augalinės praėjusio derliaus liekanos yra įterpiamos į gilesnius dirvos sluoksnius ir dirvos paviršius lieka neuždengtas. Tokios dirvos yra žymiai jautresnės aplinkos veiksniams ir lengviau pažeidžiamos vėjo ir vandens erozijos. Kiekvienais metais, pasaulyje, dėl netinkamos žemės ūkio veiklos ir kintančių aplinkos sąlygų prarandama apie 6 mln. ha derlingų dirvos plotų. Kitas labai svarbus aspektas yra tas, kad žemės dirbimas gilaus arimo plūgais yra mažai našus, daug darbo laiko ir energijos sąnaudų reikalaujantis žemės dirbimas. Tuo pačiu daugkartinis didelės masės žemės ūkio agregatų važinėjimas po dirvą ne tik daro neigiamą įtaką jos savybėms, bet ir, sudeginant didelius kiekius dyzelinių degalų, stipriai teršia aplinką šiltnamio efektą sukeliančiomis dujomis.

Full textAbstract:
This thesis aimed to develop deformable a virtual terrain which a vehicle can move in and interact with in a realistic manner. The theory used to calculate how the terrain influences the vehicle is based on terramechanics. The terrain is divided into two separate parts, one for visualization and one for physical collisions. Deformations of the graphical layer is calculated on the GPU using compute shader programming. The result of the thesis include a tech demo with a small landscape where an alternate terrain vehicle can deform the terrain as it moves around. The method for deforming the graphical layer is made in such a way so that the computational time does not increase as the size of the terrain does, making the method applicable to actual games.

INSTITUTO MILITAR DE ENGENHARIAEste trabalho de tese trata do emprego de arranjos de antenas em ambientes de comunicação móvel,dando-se ênfase ao canal de dados reverso do Sistema IS-95. Propõe-se dois estimadores: um para a direção de chegada dos sinais e outro para outros dados. Inicialmente é apresentado um estudo sobre arranjos de antenas e dos principais detalhes do sistema IS-95,especialmente a multiplicidade de acesso via divisão por códigos (CDMA).Aborda-se em seguida o problema da estimação da direção da chegada(DOA), onde se constata que os algoritmos mais conhecidos na literarura especializada, tais como Atraso-e-Soma, Capon, MUSIC e ESPRIT, não apresentam desempenho satisfatório quando empregados em ambiente CDMA. Por isso, propõe-se uma versão do método de estimação de máxima verossimilhança (ML) que utiliza a técnica denominada de EM (-Expectation Maximization-).Seu emprego permitir fracionar o problema de otimização multidimensional gerado pelo estimador ML, em últimas estimações de menor dimensão,simplificando sobremaneira a solução. O estimador proposto além da DOA,permite ainda estimar a atenuação e a defasagem dos sinais incidentes. Através de simulações, constata-se que este estimador EM apresenta um desempenho bastante satisfatório.Para tornar mais completa a análise, faz-se ainda uma comparação da variância do erro na estimação da DOA comolimitante de Cramér-Rao. Em presença de multipercursos, propõe-se quatro versões de um estimador de dados, sendo que uma delas utiliza a estrutura de treliça e objetiva a decisão sequencial dos dados. O desenvolvimento de tais estimadores faz uso de bases de espaços vetoriais para representar as funções de walsh, sendo que as operações aritméticas convencionais . Através de simulações constata-se que essas versões apresentam diferentes relações entre de desempenho e custo computacional, o que permite flexibilidade na adequação do seu emprego.
This thesis deals with antenna arrays when used in mobile communication environment, but the emphasis is on the reverse data link of IS-95. Two estimators are proposed: one for the direction-of-arrival (DOA) and other for the data. Initially, study of the antenna arrays is presented together with the main details of the IS-95 System, especially the details related to the code division multiple access (CDMA). After that, the problem of dirction- of-arrival estimation is discussed. It is shown that mostly of the known estimators, such as Delay-and-Sum, Capon, MUSIC and ESPRIT, do not offer reasonable performance when used in CDMA environment. Therefore, a new Maximum- Likelihood (ML) method is proposed using the so-called Expectation Maximization (EM) algorithm. The main advantage of using such approach is due to the fact that multidimensional optimization required by ML estimation can be split into several problems of lower dimension, thus simplifying the solution. The proposed estimator, besides the DOA estimation, also allows the estimation of attenuation and phase shift of the arriving signals. Simulations show that EM-estimator offers a fair performance when compared to other methods. In order to properly access the statistical significance of this study, the of DOA-estimation erro´s variance is compared with the Cramér-Rao Lower Bound (CRLB). Under a multipath environment, four versions of a data estimator are proposed, and one of them do employ trellis. In the development of such estimators, vector basis are used to represent the Walsh functions and the module-2 operations are replaced by convenient ordinary arithmetic operations. By means of simulation, it is shown that these versions present different levels of performance and computational cost thus allowing to choose the method according to the environmentn conditions.

Full textAbstract:
This study aims to determine whether pupils, students and teachers at various music schools feel that there is a difference in status between different music styles/genres, and if this has an impact on the individual level. The survey was conducted with a digital survey that was e-mailed to junior/high schools with music profile in the Stockholm area and to all the teachers and students at the Royal College of music in Stockholm (KMH). Due to low participation by students and teachers from the junior/high schools the students and teachers of KMH became the main object of the study. The results shows that a majority of the main group of this study feels that there is a difference in status between different music styles/genres. The study also shows that half of the participants believe that the difference in status affects them on an individual level. The discussion that follows the results focuses on the difference in status as a result of the education structure and therefore the normative structure of the school.

Full textAbstract:
This thesis outlines a research project that investigated the theory and practice of
employment relations in a large Australian company, Telstra.
The thesis takes its point of departure from the literature that has contended that there
has been a 'transformation' of American industrial relations (Kochan et al., 1986).
The literature review covers the debates that have developed around these authors'
contentions and also coverage of literature that is germane to the research project in
the areas of public sector reform and privatisation and employee participation in
organisational governance.
The research findings are presented in a case study divided into two pm1s. The first of
these parts investigates the context of employment relations at Telstra by investigating
the policy environment and technological change to which Telstra has been subject.
The second case presents the results of research into the conduct of employment
relations at Telstra.
The research finds that the environment has had a strong impact on employment
relations outcomes throughout Telstra's history. Environmental factors have
constrained performance to such an extent that moves to a more consultative and
pm1icipative approach to industrial relations within the firm have, for the most part,
been difficult to implement and have not met expectations.

Full textAbstract:
This thesis describes the results of research into provision of Production Activity Control (PAC) in Computer Integrated Manufacturing Systems for manufacture of discrete parts. The role and environment of PAC systems is described, against the background of development of the discrete parts manufacturing industry. Strategies and architectures for building PAC systems are reviewed, in terms of the goals of PAC systems, and the categorisation of existing design approaches. A novel design for a PAC system is presented. A model of manufacturing is described upon which the system design is based, and which defines the applicability of the proposed system. The heterarchical, data-driven system architecture is explained, and the way in which the system's design supports the various aspect of PAC functionality is described. A simple example is presented to illustrate the workings of the system as it accepts production orders and controls production. An experimental implementation of the system is described, and the results discussed. Recommendations for future implementations are'made in further discussion, stemming from the experiences of this experimentation, and from consideration of wider issues in the development of manufacturing technology. The thesis concludes with a brief statement of achiever nts, an'' some recommendations for directions of further research.

Full textAbstract:
This research investigated the potential of smouldering combustion to be employed as a remediation approach for soil contaminated by non-aqueous phase liquids (NAPLs). Small-scale (~15 cm), proof-of-concept experiments were the first to demonstrate that organic liquids embedded within an inert soil matrix can be successfully smouldered. Intermediate-scale (~30 cm) column experiments examined in detail the behaviour of the combustion process including its relationship to mass and energy balance and the evolution of temperature profiles. In addition, detailed evaluations of environmental parameters (e.g., soil concentrations, gas emissions) were conducted. For the first time, it was demonstrated that NAPL smouldering combustion can be self-sustaining (i.e., propagation of the smouldering front after termination of the igniter) and self-terminating (i.e., natural extinction of the reaction after all of the NAPL is destroyed). More than 30 column sensitivity experiments quantified the broad range of process parameters - including contaminant type, contaminant mass, soil type, and oxidizer flow rates - within which the process was self-sustaining and essentially complete remediation was achieved (i.e. contaminant mass removal in excess of 99.5%). Maximum burning temperatures were observed in the range 600-1100 C. Average propagation velocities varied between 0.7e-4 and 1.2e-4 m/s. Intensity and velocity of the process were shown to be controlled by the rate at which oxidizer is delivered. Contaminant type and mass was observed to affect peak temperatures and propagation velocity by influencing the energy balance at the reaction front. Moreover, mass and energy balance models were demonstrated to provide reasonable predictions of the observed propagation velocities. Overall, this research introduced an entirely new approach to the remediation of NAPL-contaminated soils and, further, advanced the understanding of the mechanisms that control the underlying process of smouldering combustion of liquids.

Swedens membership in the European Union have resulted in an international characterized labour market. The construction sector is the area who employs most posted workers among the 7400 employees who monthly enters the market. It’s also the sector where a big part of the work-related deaths occurs. The purpose of this study is therefore to contribute to a greater understanding of the regulation regarding posted workers, their work environment and the consequences of it. I have been using the right dogmatic method and a social science perspective as complement in order to answer the purpose of the study. The application of the posted workers directive has been criticized for opening opportunities for false self-employment and limiting the trade unions rights. Combined with the Laval-case the trade unions have restricted possibilities to enforce the collective agreements and protect the posted workers rights. Subcontracting processes complicates the investigation regarding which employer who has the overall responsibility for safety regulations and work environment. Foreign workers tend to be a big part in these subcontractor chains with major linguistic difficulties and lack of legislation knowledge which increases the risk of accidents. Arbetsmiljöverket is the authority who has the general responsibility for monitoring that the health and safety legislation are respected by all employers. Their investigations are partially based on the statistics of work-related accidents. But when it comes to foreign workers only more serious accidents are reported to the authority. Which means that minor incidents regarding foreign workers never reaches the statistics. In summary, conclusion is drawn that the inspection of posted workers working environment are unsatisfied. The hands of the trade unions are tied by the legislation while the inspections by the monitoring authority are based on inadequate statistics. All that combine with the fact that posted workers tend to be unwilling or lack the knowledge to take action for their rights, leads to openings for employers to take advantage of foreign workers.

Full textAbstract:
The main purpose of this study is to find whether virtual teams perform as effectively as face-to-face teams and if not, whether solutions can be derived to improve the levels of performance. To this end, the study compares the performance and satisfaction perception levels of virtual teams with face-to-face teams in a learning environment. In order to develop a sound framework for the research, a detailed literature review of prior research encompassing team satisfaction and performance in face-to-face and CMC (Computer Mediated Communication) supported environments was undertaken. Additionally the researcher performed a meta-analysis of previous research studies and from these was able to build a research framework to fit the particular context of this study. This framework has strong statistical power and a solid theoretical base.

Magister Legum - LLM (Mercantile and Labour Law)Most developed countries that enjoy the lion's share of foreign investment do not have domestic legal frameworks on foreign direct investment. This is because investors are attracted by a holistic picture of these countries. Such countries have strong institutions of governance, enjoy political and economic stability, embrace democracy, have respect for rights, and have high levels of development - factors which attract investors. In terms of regulation, many of these countries are heavily reliant on bilateral investment treaties. However, this is not the case in developing countries such as Zimbabwe. The existence of an effective and efficient legal framework on the governance of foreign direct investment is an important consideration for investors. This emanates from the fact that developing countries often have weak legal systems, shaky economies and uncertain political environments.

Full textAbstract:
Designer drugs are compounds which have been synthetically derived from illicit drugs. After consumption, drugs and their metabolites are introduced into the sewage water which is treated and disposed into the environment. A combined target, suspect and non-target workflow was created to detect designer drugs in environmental water samples. Multiple water samples were spiked with an unknown mixture of drugs and metabolites to assess the efficiency of the method. Samples were collected from sewage influent and effluent pipes, downstream from a sewage outfall and reclaimed water. Analysis was conducted with high resolution MS using the QExactive Orbitrap. Screening was performed using a database compiled in-house using TraceFinder EFS. Structure confirmation was achieved using MassFrontier. Target drugs and their metabolites were detected in sewage influent but not in sewage effluent, downstream of the effluent pipe, or in reclaimed water. The workflow was adequate to detect designer drugs in multiple water matrices at concentrations as low as 20ppt.

Full textAbstract:
Karlstads Energi AB:s vågstation vid Hedenverket i Karlstad är en anläggning där invägning och analys av träbränsle utförs. Provtagning och hantering av träbränsle hör till de dagliga arbetsuppgifterna för personalen. Vid nära hantering av trämaterial finns risken att exponeras för trämögelsporer. Exponering av mikrobiologiska luftföroreningar kan orsaka hälsobesvär på lungor och luftvägar hos människor. Efter utförd riskbedömning av vågstationen noterades en oro att trämögelsporer och dammpartiklar sprids bortom lokalen för provtagning av träbränsle till andra utrymmen. Bedömningen talar för att ventilationen kanske är bristfällig och inte är anpassad för den aktuella verksamheten. Potentiell spridning av trämögelsporer via hantering, undermålig städning samt via kläder och annan utrustning tillhörde även problematiken. Syftet med detta arbete var att vid provtagningen av träbränsle förtydliga spridning och exponering av luftburna trämögelsporer i arbetsmiljön. Detta med avsikt att identifiera områden och arbetsrutiner där förebyggande åtgärder mot spridning av trämögelsporer kunde införas. Målet var att definiera luftrörelser i lokalen till följd av arbetsrutiner och ventilation. Resultatet från undersökningen fungerade som ett underlag för utvärdering av åtgärder mot spridning och exponering av trämögelsporer. Genom mätningar och observationer kunde luftrörelser och föroreningskällor identifieras. Mätningar avsåg luftens temperatur och hastighet i lokalen. Ventilationen undersöktes genom observation av luftrörelser och inventering av ventilationsutrustning. Arbets- och skyddsrutiner observerades utan social interaktion från observatören. Resultat från mätningar och observationer analyserades och jämfördes med riktvärden presenterade i litteratur, forskningsarbeten samt Arbetsmiljöverkets föreskrifter. Ventilationen i lokalen för provtagning av träbränsle konstateras vara bristfällig för pågående verksamhet. Spridning och exponering av hälsofarliga trämögelsporer utgörs av bristen på tillräcklig processventilation, långa horisontella luftflöden, stillastående luft och cirkulerande av förorenad luft. Observation av arbets- och skyddsrutiner visar på bristande inneslutning av föroreningskällor. Det är även dålig användning av personlig skyddsutrustning samt genomförande av städning. Utifrån resultaten kunde flera förebyggande åtgärder föreslås. Införande av processventilation och reformering av ventilationssystem skulle leda till mindre spridning av trämögelsporer och bättre luftutbyte av lokalen. En granskning av arbets- och skyddsrutiner liksom införande av nya rutiner med en medvetenhet om trämögelsporers förmåga att spridas via luften föreslogs som åtgärd mot exponering.Karlstads Energi AB's weighing station at Hedenverket in Karlstad is a facility where weighing and analysis of wood fuel are carried out. Sampling and handling of wood fuel is one of the daily duties for the staff at the weigh station. At the close management of wooden material there is a risk of exposure to airborne mold spores. Exposure to microbiological air pollution may cause health problems in the lungs and airways of humans. After performing the risk assessment at the weighing station there was concerns that mold spores and dust particles spread beyond the premises for the sampling of wood fuel to other areas. The assessment indicates that the ventilation may be inadequate and is not adapted to the current work environment. Potential spread of mold spores through handling, poor housekeeping and by clothing and other equipment also belonged to the uncertainties. The aim with this study was by the sampling of wood fuel to clarify the dispersion and exposure to airborne mold spores in the work environment. This is with the intention to identify areas and work routines where preventive measures against the spread of mold spores could be introduced. The goal was to define the air movement within the premises of wood fuel sampling as a result of working practices and ventilation. The results of the study served as a basis for the evaluation of measures against the spread and exposure of mold spores. By measurements and observations the air movements and sources of contamination within the premises could be identified. Measurements relate to the air temperature and air velocity within the premises. The ventilation was investigated by observation of air movement and taking inventory of the ventilation equipment. Work and protective practices were observed without any social interaction by the observer. Results of measurements and observations were analyzed and compared to guidelines presented in literature, research works and the Swedish Work Environment Authority's constitution. The ventilation of the premises for the sampling of wood fuel was found to be flawed for the current work environment. The dispersion and exposure to hazardous mold spores is the lack of sufficient exhaust ventilation, long horizontal air flow, stagnant air and circulating of contaminated air. Observations of work and protective procedures show an insufficient containment of pollution sources. It is also poor use of protective equipment and carrying through with cleaning. Based on the results could several preventative measures be proposed. Introduction of additional exhaust ventilation and reforming of the ventilation system would result in less spread of mold spores and a better air exchange of the premises. A review of work and protective procedures as well as introducing of new procedures with an awareness of mold spores ability to spread via air was suggested as a measure against exposure.

This master‘s thesis deals with ecotoxicity assessment of plasma-activated solutions. Various plasma-activated solutions were prepared in the experiments. In the vast majority of tests, it was plasma-activated tap water – PAW. Depending on the test organism, dilution water was further processed, namely dilution water for Thamnocephalus platyurus and Daphnia magna. In this master‘s thesis the ecotoxicological effects were assessed through aquatic ecotoxicity tests with an aquatic plant Lemna minor, on a crustaceans T. platyurus and D. magna and on agricultural crops Lactuca sativa and Allium cepa L. . Crustaceans are fresh-water organisms on which the water contamination can be quickly and quite easily assessed. These plasma-activated solutions were also tested for acute ecotoxicity of soil organisms by ecotoxicological contact tests with Eisenia fetida, springtails Folsomia candida and seeds of L. sativa. Tests on T. platyurus and D. magna were performed in time intervals and a change in mortality was observed depending on PAW concentration. If the test results allowed, the LC50, IC50, A and NR escapism values were calculated. When the measured and calculated values did not allow such a calculation, the overall effect of PAW on organisms was assessed and a significant difference was calculated for the L.sativa root growth inhibition test. The final results showed that PAW has an ecotoxic effect on aquatic organisms, while it has rather beneficial effects on terrestrial organisms.

The use of smart phones has changed the lifestyle of the society. Almost all kind of useful tools you can find on your smart phone. People used to buy goods every day. And for the purchase of goods they must pay. Security is very important while payment is concern. In this thesis we have designed and demonstrated a mobile phone application that can be used for a small shop or a big market. For any kind of commerce application, three different kind of entities are mostly involved: the customer, the sales person, and the management of the shop. Our designed mobile application has three different interfaces for three different kind of users: Manager Interface, Employee Interface, and Customer Interface. An interface for the system administrator is also designed, which should be used as an desktop application on the point of sale server. This application is flexible with capabilities of different payment options. Our proposed design can be implemented in any smart phone environment for example Android, iOS or Windows phone. This design provides availability, confidentiality, and integrity of payment data.

Full textAbstract:
This study presents a critical discourse analysis of workplace health at the Swedish Church in Umeå. The analysis in this paper is based on Carol Bacchi‟s theoretical framework “What‟s the problem represented to be?”, which helps to build an insight on the common sense understanding that what we propose to do about something reveals what we think needs to change and hence what we think the „problem‟ is. The main area has been focused on (1) working hours and workload (2)competence transmission and (3) discrimination. The analysis of the policy documents shows that work hour and work load due an independent work enviroment for most of the professions in church, create an individual liability in relation to competence and qualification. It also reveals an assumption that the surrounding, a revival legacy where the Church of Umeå act, created a positive/affirmative action trough competence transmission between older vicars and younger female vicars to cope a long-term male dominated profession. The study also found that competence transmission between older and younger employees create an implied assumption of alack in competences among younger employees. To prevent discrimination a key concept was to promote good work relationships. That means through constructions of equality and gender equality. A possibly effect of the policy of equality, where it´s assumes that everybody has to take responsibility to prevent discrimination, but allows individual interpretations created a risk that the actions to whom it concerns fails. It also shows that the individual government was highly depending in the relations of power as the victim - violates and also in the relationship employee –employer as a junior partner or superior partner.Syftet med denna uppsats att analysera hur framställningen av psykosocial arbetsmiljö är utformat i policydokument inom Svenska kyrkan i Umeå i relation till tidigare forskning. Analysen i uppsatsen baserar sig på Carol Lee Bacchis metod What´s the problem represented to be? som syftar till att ge en insikt av bakomliggande problem i policydokument och hur man ämnar förebygga arbetsrelaterad ohälsa. Utgångsläget var att studera det konkreta förslaget och utifrån det utläsa vad det egentliga ”problemet” är. Analysen resulterade i ett fokus på områdena för 1.) arbetstidens förläggning och arbetsbelastning, 2.) kunskapsöverföring och 3.) kränkande särbehandling. Studien fann att det förebyggande åtgärderna inom ramen för arbetstidens förläggning och arbetsbelastning utgår från att arbetsrelaterad ohälsa ska förebyggas genom arbetsgivarens ansvar för att arbetsbelastning och krav ligger i linje med medarbetarnas kompetens och förmågor. Flertalet yrken inom kyrkan förväntas själva kunna avgöra när arbetsinsatser är rimliga, varför det ändå kunde ses bli en individfråga huruvida arbetsbelastningen kan bli relaterad till kompetens och förmåga. Det återfanns även föreställningar om kön utifrån Umeå pastorats omgivning av väckelse arv som kan skapa en positiv särbehandling som diskurs genom kompetensöverföring mellan äldre och kvinnliga yngre präster för att hantera ett länge mansdominerat yrke. Studien fann även att ålder utifrån insatser om kompetensöverföring mellan yngre och äldre skapade en underförstådd föreställning om kunskapsbrist i relation till yngre medarbetare. Inom ramen för att motverka kränkande särbehandling blev nyckelkoncept som främjande av konstruktiva arbetsrelationer viktig. Det innebar att utifrån konstruktioner av jämlikhet och jämställdhet förebygga kränkande särbehandling. En effekt av policyn för jämlikhet där alla förväntas ta ansvar och att man tillåter egna tolkningar, riskerade att skapa en otydlighet till vem insatserna riktar sig till och där individe nblev produktivt styrande i maktrelationerna som den utsatte vs. den som kränker och som anställd i förhållande till arbetsgivaren.

Full textAbstract:
The purpose of this paper is to explore group creative processes in a virtual environment to better understand how virtual communication influences creativity. After reviewing literature, a theoretical foundation in creativity was established and with three common themes derived: Task motivation and task orientation, social environment and participation, and communication. This was coupled with a review of current virtual team interaction theories, demonstrating intersections between them. The method used was a qualitative exploration using semi-structured in-depth interviews. The interviews were conducted via VOIP, with notes and recordings taken for further analysis. Analysis was conducted on the three common creative themes viewing virtualization as the mediator. Trends emerged demonstrating that asynchronous communication had a substantial influence on group creative processes. Conversely, virtual teams employing real-time communication found little influence on the creative process. Other anecdotal trends can be seen regarding motivation and social environment. This paper identifies key areas where virtualization influences the group creative process, and provides a base for future suggested research.

Abstract:
Job satisfaction has great significance for nurses. The job is very demanding and requires a great deal of responsibility. Low job satisfaction and organisation changes affect their work negatively. The aim of the study was to investigate the nurses’ job satisfaction and job situation. Legitimate nurses at a medicine department of a hospital situated in the middle of Sweden were interviewed for this purpose. The study is descriptive and the qualitative approach has been used. The data was analysed with content analysis as described by Graneheim and Lundman. The study investigates the factors affecting nurses’ experiences as far as job satisfaction and job situation are concerned. The nurses’ opinions on what should be done to improve their work environment are also discussed in the study. The result shows that the nurses’ job satisfaction and job situation is affected by the collaboration between the colleagues and the management, as well as job related stress and work environment.

The purpose of this thesis is to examine how teachers work and reflects on gender education in preschools. We also want to take part of how teacher’s thoughts are reflected in the physical indoor environment and how the environment is designed by reviewing the rooms furnishing and the selected materials. We will do this by visiting a number of preschools located in Stockholm and New York. We have chosen three questions to get the answers on our purpose. How teachers reflect around gender pedagogy are, and how the thoughts are expressed in the practical work. How the teachers communicate with their co-workers about gender pedagogy. How the teachers own thoughts and reflections on gender pedagogy have been expressed in the physical indoor environment where the children stay during the day. We have used interviews and observations as a method to gather the information that we needed to answer our questions of the thesis. We have used the sociocultural perspective, variation theory and queer theory as a ground to analyze our gathered information. As a conclusion we have found that the teachers have different ways of reflecting about gender pedagogy but they still don´t want to focus their work on it. They would rather focus their pedagogy on working with equality, which for them means more than just gender. We have reached that to find a way you work sustainable with gender pedagogy you have to have an open minded attitude towards the children, have critical standards, and an environment where children can grow and learn without focusing on gender.

Mental ill-health is a common cause of today's sick leave and the World Health Organization predicts that mental illness will be the leading cause of sick leave in the world by 2030. In this essay I examined how the municipality X invested in a project on health promotion and mental ill-health for all leaders and politicians with the aim of reducing sick leave and staff turnover throughout the municipality. The question is whether the project was the right effort and what conditions and eventual obstacles exists for health promotion work in practice. To find out, six managers were interviewed within two units and a project manager based on a semi-structuredinterview. The interviews were transcribed and analyzed. The examination shows that the project was not the right effort in the units that my investigation concerns. The unit managers have bad prerequisites for working health promotion since there in not enough human resources and time. Health promotion work is prioritized and does not permeate the entire administration. The interviews show that there is a lack of trust and openness, lack of a ''we'' feeling in groups and focus on individual interests in managements. The examination shows that other efforts are needed to solve the problem and that effort should be at a more general level in the municipality.Psykisk ohälsa är en vanlig orsak till dagens sjukskrivningar och World Health Organization förutser att psykisk ohälsa redan år 2030 kommer att vara den främsta orsaken till sjukskrivningar i världen. I den här uppsatsen undersöktes hur kommunen X satsat på ett projekt om hälsofrämjande arbete och psykisk ohälsa för alla ledare och politiker med syftet att minska sjukfrånvaro och personalomsättning i hela kommunen. Frågan är om projektet var rätt insats och vilka förutsättningar och eventuella hinder föreligger för hälsofrämjande arbete i praktiken. För att ta reda på detta intervjuades sex chefer inom två enheter och en projektledare utifrån en semistrukturerad intervju. Intervjuerna transkriberades och analyserades. Av undersökningen framgår att projektet inte var rätt insats i enheter som min undersökning berör. Enhetscheferna har dåliga förutsättningar att jobba hälsofrämjande då det inte finns tillräckligt med personalresurser och tid. Hälsofrämjande arbete prioriteras och genomsyrar inte hela förvaltningen. Det framgår av intervjuer att det är brist på tillit och öppenhet, saknad av “vi” känsla i grupper och fokus på individuella intressen i förvaltningen. Undersökningen visar att det behövs andra insatser för att lösa problemet och den insatsen ska ligga på mer övergripande nivå i kommunen.

Full textAbstract:
Psychotic disorders can be defined as disorders of adaptation to social context. Although heritability is often emphasized, onset must be considered as the end-point of a pathway which involves: 1) genetic heritability; 2) environmental factors; 3) psychopathological factors. Therefore, the current challenge consists in combining different scientific fields aiming at a deeper comprehension of psychotic disorders. Taking off these considerations, this thesis will present research conducted in Rome (Children Hospital Bambino Gesù) and in Birmingham (Department of Psychology, University of Birmingham) by the Author during his PhD. These research are focused on two possible models which can help to better understand the role played by gene/enviroment interaction in the pathogenesis of psychotic disorders. The first model concerns the so-called psychotic-like experiences and is therefore situated in the sphere of the psychopathological factors involved in the pathway to psychosis. The second model concerns 22q11 microdeletion syndrome, a genetic syndrome with high prevalence of psychotic disorders. The thesis starts with a comprehensive review of these topics. Subsequently, the main findings of the research conducted during the PhD will be described and analyzed. Implications are explored, in terms of clinical practice, aetiological pathways, potential treatments and intervention strategies.

El objetivo general del presente trabajo es analizar la relación entre la economía y el ambiente a diferentes escalas. Esto ha de ser comprendido como la elección de un problema de investigación en cada dimensión, y aplicar las herramientas de análisis que mejor se ajustan a éste. El presente documento esta divido en tres partes.
La Parte I se aproxima al análisis de la relación entre economía y ambiente desde la dimensión internacional. El Capítulo 1 estudia la relación entre las emisiones de CO2 y la actividad económica para 31 países (28 OECD, Brasil, China e India) durante el período 1950 – 2006. Se estima la relación de largo plazo para los países de forma individual. La homogeneidad entre países respecto a la forma funcional, los parámetros, y el punto de inflexión, cuando corresponde, son rechazadas. Esto confirma la importancia de considerar las diferencias entre países en la relación entre contaminación del aire y la actividad económica para así evitar estimaciones y conclusiones erróneas.
La Parte II analiza la relación entre economía y ambiente desde una perspectiva nacional. Esta parte está dividida en dos capítulos. El Capítulo 2 identifica los sectores clave respecto a las emisiones de gases de efecto invernadero de la economía Uruguaya a través del análisis insumo – producto. Buscando guiar el diseño de políticas de mitigación, la responsabilidad de cada sector es descompuesta entre la contaminación que éstos generan a través de sus propios procesos productivos y aquella que generan de forma indirecta. Además, se analiza el rol de la demanda externa. Los resultados muestran que todos los sectores clave son relevantes debido a sus propias emisiones, excepto el sector de Venta de automotores y combustible al por menor. Además, los sectores Construcción, y Hoteles y restaurantes presentan efectos muy indirectos. Finalmente, la demanda externa es el impulsor de las emisiones de metano y de óxido nitroso, mientras que las de dióxido de carbono consecuencia principalmente de la demanda interna.
El Capítulo 3 analiza las emisiones de metano del subsistema agro-industrial y las de dióxido de carbono del subsistema de sectores de servicios para Uruguay en 2004. La relación de estos subsistemas con el resto de la economía se analiza a través de la metodología insumo – producto, empleando una descomposición multiplicativa. Ésta es combinada con una descomposición aditiva para estudiar los vínculos dentro de los subsistemas. Este enfoque permite estudiar la relevancia de estos subsistemas como unidades particulares de la estructura económica, así como el análisis en particular de cada uno de los sectores pertenecientes a los subsistemas. Los resultados muestran en que sectores las políticas de mitigación serán más efectivas, y si es mejor implementar medidas para fomentar las mejoras tecnológicas y de mejores prácticas, o a través de políticas de demanda.
Por último, la Parte III toma una perspectiva local para analizar la relación entre la economía y el ambiente. El Capítulo 4 aporta evidencia experimental respecto al efecto de los castigos no monetarios de los pares entre comunidades de pescadores de Uruguay cuando explotan un recurso de uso común. Los resultados muestran: a) los grupos conformados por pescadores de diferentes comunidades reducen su nivel de extracción como respuesta a la posibilidad de que su comportamiento sea desaprobado, b) la efectividad del castigo no monetario disminuye como consecuencia de la presencia de castigo anti-social y debido a que los individuos anticipan de forma correcta la probabilidad de ser castigados si incrementan su nivel de extracción. Finalmente, c) los individuos ajustan sus decisiones entre períodos de manera de converger al promedio de sus compañeros en el período anterior. Esto evidencia la existencia de fuertes efectos de conformismo.The general objective of this thesis is to analyze the relationship between the economy and the environment at different scales. This must be understood as choosing a research problem at each dimension, and to apply the tools that better fit to analyze each problem. The present document is divided in three parts. Each part corresponds to one dimension, and policy implications are directly derived from the analysis. Part I approaches the relationship between the environment and the economy from an international dimension. Chapter 1 explores the relationship between CO2 emissions and economic activity for 31 countries (28 OECD, Brazil, China, and India) during the period 1950 to 2006. Single country long run relationships are estimated, and equality in the functional form, the parameters, and the turning point, when appropriate, are rejected. This confirms the relevance of considering the differences among countries in the relationship between air pollution and economic activity to avoid wrong estimations and conclusions. Part II analyses the relationship between the economy and the environment from a national perspective. This part is divided in two chapters. Chapter 2 identifies the key sectors in greenhouse gas emissions of the Uruguayan economy through input–output analysis. In order to guide mitigation policy design, we decompose each sector’s responsibility into the pollution generated through its own production process and the pollution indirectly generated in the production processes of other sectors. In addition, the role of external demand is analyzed. The results show that all the key polluting sectors are important because of their own emissions, except for the Motor vehicles and oil retail trade sector. Moreover, very indirect effects are found through Building, and Hotels and restaurants. Also, Financial intermediation may be relevant for the design of mechanisms to encourage cleaner production. Finally, external demand is the main driver for methane and nitrous oxide emissions, while carbon dioxide emissions are mainly driven by domestic demand. Chapter 3 analyzes methane emissions of the agro industrial subsystem and carbon dioxide emissions of the services sectors subsystem in Uruguay in 2004. The relationship of these subsystems with the rest of the economy is analyzed through input–output methodology employing a multiplicative decomposition. This is combined with an additive decomposition for the study of the linkages within them. This approach allows to study the importance of these subsystems as units in the economic structure as well as to analyze in detail the relationship between the different branches in each of the subsystems. The results depict in which sectors mitigation policies are more effective, and if they would be better tackled through technical improvements and better practices, or through demand policies. Finally, Part III takes a local perspective for approaching the analysis between economic activities and the environment. Chapter 4 provides experimental evidence on the effects of non-monetary punishment (NMP) by peers among communities of Uruguayan fishers exploiting a common pool resource (CPR). We find that: a) groups composed of fishers from different communities (out-groups) reduced their exploitation of the resource in response to the threat of punishment; unlike experimental groups from a single community (in-groups), b) NMP effectiveness is diminished because of the presence of antisocial punishment and because individuals correctly anticipate that the likelihood of being punished is increasing in extraction levels. Those who would experience disutility by being punished reduce their extraction levels beforehand while those that do not care about social disapproval maintain their extraction at high levels. Finally, c) individuals adjust their period-by-period decisions in order to converge with their peers’ average in a previous period, showing strong conformity effects.

I mina resultat har det framkommit att förskolans pedagoger är en viktig del av barns sociala utveckling. Det är i förskolan man får sina första upplevelser av vänskap, men det är också där i relationerna som man kan bli utsatt, eller utsätta andra, för verbal kränkning. Den fysiska miljön är av betydelse för förekomsten av kränkande språk och det föreligger en ökad risk i de icke pedagogstyrda aktiviteterna.This study examines preschool theatchers' perceptions of abusive language among children and the purpose is to expose their ideas of abusive language impact on children's socializing process.

För att ta reda på hur barn tänker om att vara ute på förskolan har jag gjort observationer och intervjuer med barn i ålder 3-5 år, på tre förskolor i en och samma kommun. Utemiljön på förskolorna är likartad, det som skiljer förskolorna åt är den pedagogiska inriktningen. Syftet har varit att ta reda på om det finns skillnader och likheter i barnens sätt att tänka. Hur de förstår årstidsväxlingar och hur der ser på sitt eget lärande. För mig som pedagog är det viktigt att utgå från barnens perspektiv. Genom att lyssna på barnen och sedan använda utemiljön som ett verktyg kan jag skapa bra förutsättningar för barns utveckling och lärande.
På de tre förskolorna leker barnen i stort sett samma lekar och använder samma redskap. Vid intervjuerna har barnen gett likartade svar och det som skiljer dem åt är barnens erfarenheter i och med deras ålder och utveckling.
I have investigated, through observing and by interviews in three preschools in the same community, what children at the age 3-5 years think about the surroundings at their preschool. The outdoor enviroments at the different preschools are more or less the same but the preschools differ in their pedagogies. The intention with the interviews was to find out if there were any similarity or difference between children how they think about the changes in seasons and how their learning skills progress. For me as a pedagogue it is very important to look at children from their perspective. I have to listen to what children talk about and how the outdoor enviroment is used as a tool to create the necessary conditions for childrens progress and learning.
At the three preschools the children were playing the same type of games and used the same tools to activate themselves. In the interviews children have given similar answers and the difference them has to do with their own age dependent experiences.

With the dramatic changes in the global climate, more and more natural disasters, all cause of considerable influence on human living environment. In recent years, has become a national scramble to issues of concern. The human to city center, how to maintain economic growth while reducing carbon dioxide emissions, to achieve sustainable human lifestyle is bound to go low-carbon development planning, therefore, to develop the concept of low-carbon city, The research uses DEA to evaluate efficiency of low-carbon in 19 counties of Taiwan during the period 2010 to 2011. Single phase efficiency evaluation shows that Chiayi City, Keelung City, Taipei City, Taitung County , Pingtung County and Nantou County, achieve the efficient frontier. While the remaining counties wished to raise the efficiency value is required from the oil, gas, electricity abatement and increase in disposable income per household and owned forest area views. Intertemporal Malmquist Index shows, over the past two years, cities have progressive condition in economic development and environmental efficiency; while the remaining counties should focus on total factor productivity rise through technical efficiency improvement. Finally, consider both current and intertemporal efficiency, the best performance in Chiayi City, suggested that other cities and counties can improve efficiency according to various indications ,in order to reach the goal of a low carbon city.

Since a lot of enterprises still have difficulty in evaluating the complexity of their Intranet systems, it is an extremely demanding task for them to identify valid and potentially useful patterns from the huge amount of documents in the Intranet. In order to solve this problem, it is essential to take a close and careful examination of the different Intranet frameworks, so that appropriate data mining approaches and techniques can be worked out. This research began with a literature review of the fields of data mining and Intranet applications in Taiwan. Based on the review of current theories and practices, the second part of the research focused on the dimensions which we need to consider for evaluating the complexity of Intranet systems. In the third part of the research, basic frameworks for simple and complex Intranet data mining systems were then proposed, three types of data mining approaches suitable for simple and complex Intranet systems were designed and a prototype for implementing two approaches were developed. Han’s (1995) “concept hierarchy” and “multiple layered database” and Yang & Chin’s (2000) approach of Internet data mining were adopted as the major bases. Besides, this research also paid particular attention to the issues of “authorization” and “knowledge view” when designing the software and developing the prototypes. In the last part of the research, the feasibility, practicality and potential uses of the data mining approaches and prototype were discussed and some directions for future research were suggested.

Consumers often form complex social networks based on a multitude of different relations and interactions. By virtue of these interactions, they influence each other’s decisions in adopting a product or behavior. Viral marketing takes advantage of these social network effects, wherein friends recommend a product to their friends, who in turn recommend it to others, and so forth, creating a cascade of recommendation. Given a social network, a natural question thus emerges in the area of viral marketing: If we wish to maximize the size of a cascade, which subset of consumers should we target? This influence maximization problem has been proposed and studied in previous researches. Though previous researches shed light to this interesting problem, their views of social networks are highly idealistic. First, previous researches assume that a social network is static. Hence it is an interesting question to consider how a company may effectively infiltrate a market in which the structure of consumer network is evolving and a stronger competing company is present. In this research, we utilize the search and adaption capacity of ant colony optimization (ACO) algorithm to solve the influence maximization problem. The proposed approaches are evaluated by using real-world data and the experimental results show that Node’s Influence approach has the best performance in competitive and dynamic social networks.

The rapid growth of Internet and Electronic-Commerce has the potential to provide enormous benefits to business and consumers. People spending more and more time navigating the Web sites. But some times they feel they were lost when dealing with large amount of data and information. There must be a mechanism to help people acquiring data more systematically and much more quickly. The Web query languages such as XML-QL, WIDL, GIDL provide users with collecting data from the Web server automatically. But it is difficult to write sophisticated syntax for specific Web sites. In this thesis we introduce a user-friendly tool based on GIDL for Web data extraction. The GUI based Web data extraction tool will accelerating the process of extracting data from the Web. The utility will also increase the performance for Web data extraction and reduce the cost.

In the point of the view of structure’s life cycle, design a building structure in civil engineering involves many different sub-tasks during the whole process. Integration of these tasks to an integrated system is very difficult and, in the past, it is simply linking stylized work. The performance, however, isn’t very well and expansion becomes more difficult due to the repetition of the data source probably occurs frequently. During the structure’s life cycle, the design process can be divided into several sequential stages. Meanwhile, the structure will be treated as a combination of several components. Hence, creating a database for the structure to represent these data source is necessary and a feasible approach. The database of the structure must consider the expansion in the future. In this work, an integrated system for design building structures has been developed. The stages of structure analysis and drawing are considered as two sequential processes to demonstrate the feasibility of the model. The model is built on client/server model; that is, the processes are distributed in different platforms that can be connected with local network. The model can automatically synchronize these stages if they can perform simultaneously. The simulation results show that the integrated system can link connected tasks synchronously; initiate corresponding process automatically as it is requested; and perform the whole design task through a network environment.

n this thesis, we build a Bluetooth protocol driver in both the PDA and the windows environment. This Bluetooth protocol driver implements three layers as described in Bluetooth specification, one is Host Controller Interface layer and one is Logical Link Control Adaptation Protocol layer and the other is RS232 Serial Cable Emulation Protocol layer. These layers provide the abilities as writing Bluetooth applications in the Penbex PDA and Microsoft Windows environment. We also define a hardware abstract layer for supporting the dierent CPU and the dierent physical bus between Bluetooth protocol driver and Bluetooth device. Based on our Bluetooth protocol driver, we build a set of functions that the programmers can use them to build their applications. These Bluetooth protocol stack layers can help programmers who want to port the original socket or UART style programs to Bluetooth or write the communication programs with this Bluetooth protocol stack. Then we make it possible to run with the GNU C compiler or Microsoft Visual C++ compiler. In our first experiment, we write test programs based on our Bluetooth protocol driver to transmit data of dierent size through the three dierent layers in the several times to measure the bandwidth of the Bluetooth protocol driver and the overhead of these layers. The experiment is done with a pair of EBDK systems on the Penbex PDA SDK 2.0b8 and Microsoft Windows. The experiments show that we have a robust software environment and illustrate application scenario
