Este trabalho tem como objetivo analisar mudanças de curto prazo na performance escolar relacionadas à implantação das UPPs na cidade do Rio de Janeiro. Avaliamos o efeito da ocupação policial pré-UPP nas notas de exames bimestrais aplicados em escolas municipais da cidade. Para reforçar a interpretação de efeito causal, usamos como pressuposto de identificação o fato de a decisão de implantar as UPPs em determinadas favelas seguir principalmente motivações independentes de características de alunos que afetem suas notas, o que nos permitiria utilizar um estimador de diferenças-em-diferenças com efeitos fixos. Além disso, utilizamos um argumento semelhante ao de Autor (2003) com a avaliação dos efeitos do tratamento em períodos anteriores e posteriores ao do tratamento a fim de facilitar a interpretação dos efeitos como causais e gerar mais informações sobre a heterogeneidade no tempo dos efeitos das UPPs nas notas.

Finn upps ämnesverktyg är ett imponerande inspirationsverktyg för teknikundervisande lärare. Genom att identifiera och lösa ett problem, så får man eleverna att tänka i nya banor. Undervisningsmaterialet och lärarhandledningens upplägg, ger lärarna möjlighet att använda det i sin helhet eller bara välja ut enskilda delar. Men vilka erfarenheter har lärarna erhållit genom att arbeta med ämnesverktyget i undervisningen? Undersökningen genomfördes via en webbaserad kvantitativ enkät. Resultatet av undersökningen visade att eleverna lättare uppnått delar av skolans mål i teknik med stöd av Finn upps ämnesverktyg. En majoritet av lärarna instämde i att elevernas kvalitativa kunskaper påverkades positivt, vilket kunde leda till ett högre betyg. Dessutom intresserade sig flickorna mer för teknikämnet än tidigare forskning visat.

O trabalho em tela tem como principal interesse analisar o funcionamento e as representações acerca do trabalho desenvolvido pela Ouvidoria das UPPs. O ponto de partida da pesquisa foi verificar o quanto se confirmava ou não a expectativa da ouvidoria como um canal privilegiado de comunicação entre polícia e comunidade em favelas com Unidades de Polícia Pacificadora (UPPs). De modo geral, buscou-se compreender quais dificuldades os policiais envolvidos com a Ouvidoria das UPPs encontravam para a implementação de uma política de segurança pública que valorizasse ideias como participação e accountability – marcos ideológicos fundamentais para organizações policiais nas democracias modernas. Argumenta-se que, a despeito da expectativa de que ouvidorias devessem atuar no campo do controle externo, a Ouvidoria das UPPs devido uma série de características estruturais e do contexto de extrema violência armada nas favelas cariocas funciona basicamente como um serviço para realização de denúncias de crime organizado.
This work has as its main interest to analyze the performance and the representations around the job done by UPPs Ombudsman. The research s jump start was to verify if the expectations could be confirmed or not about the ombudsman as a privileged channel between the police and the community in the slums with the Pacifying Police Units (Unidades de Polícia Pacificadora – UPPs). In an overall, it was tried to reach the understanding of which difficulties were found by the policeman involved with the UPPs Ombudsman, to implement a police of public security which appreciate ideas like participation and accountability – fundamental ideals for the police organizations in the modern democracies. It has been told that, despite of the expectation that the ombudsman should act in the external control field, the UPPs Ombudsman, due to a lot of structural characteristics and from the context of extreme weaponized violence in the carioca slums, it basically works as a service of reporting complaints of the organized crime.

Ao longo do século XX o Rio passou por amplas reformas urbanas, sempre focadas em pontos estratégicos da cidade. Hoje, mais uma vez, vivenciamos um profundo reordenamento espacial, notadamente na Zona Oeste. No âmbito político da segurança pública, o governo estadual implanta as Unidades de Polícia Pacificadora (UPPs), em comunidades consideradas perigosas pelo poder do tráfico de drogas ali presente. O programa que começou em 2008 com 2 comunidades ocupadas, hoje já atinge 24. A partir daí uma rápida mudança da abordagem do jornal O Globo sobre os problemas da cidade tem acontecido. A violência, que antes era destaque nas páginas desse periódico, de 2009 pra cá vem ocupando um plano secundário.

Full textAbstract:
Nessa dissertação procede-se à análise das narrativas do jornal O Globo durante a ocupação da favela da Rocinha pelas forças oficiais, em novembro de 2011. Pretende-se identificar as representações veiculadas pela mídia nesse especial momento da vida da cidade, que convive com a implantação do projeto das Unidades de Polícia Pacificadora UPPs e a expectativa de recepcionar, nos próximos anos, dois megaeventos esportivos internacionais: a Copa do Mundo (2014) e as Olimpíadas (2016). O mote da pesquisa foi, através da análise das representações sobre o processo de ocupação, descobrir pistas que permitissem pensar o impacto dessa medida sobre a cidade e seus habitantes. Foi possível perceber que, diferentemente do que ocorria nas últimas décadas, a violência urbana não se apresentou como questão de grande interesse para o jornal, aparecendo apenas incidentalmente como eventos pontuais em um contexto predominantemente pacífico. Prevaleceu o discurso otimista em relação à cidade e seu futuro. Nesse sentido, diversas matérias registraram o sucesso da operação policial, comemorando a substituição da política policial de confronto pelas ações de inteligência, fator que teria permitido a retomada do morro sem que um tiro sequer fosse disparado. Ênfase especial foi dada às UPPs, sistematicamente representadas de forma positiva pelo jornal, moradores, empresários e especialistas, que apontariam o projeto como fator responsável pela onda de esperança e otimismo que envolve a cidade. As UPPs seriam, ainda, o elemento que permitiria, aos cariocas, ressignificar as favelas da cidade, afastando a aura de violência a elas associadas, fazendo desaparecer o medo que esses espaços da cidade historicamente causam na população em geral, integrando as favelas na cidade formal. O processo de pacificação das favelas do Rio de Janeiro, personificado nas UPPs, seria a ponte que permitiria, à cidade, se redescobrir, se reinventar, recuperando a alegria e a auto-estima, deixando para trás as décadas de pessimismo e desesperança. Observou-se, assim, que durante o período pesquisado, a dinâmica das narrativas rompeu com o padrão anterior de representação de cidade violenta, privilegiando o discurso da cidade pacificada, embora com episódios violentos pontuais.The research draws your attention towards the narratives of the newspaper O Globo during the occupation of the Rocinha favela by official forces in November 2011. Intended to identify what kind of representations was reported by the media at special moment of city life, which coexists with the implementation of the project of Pacifying Police Units (UPPs) and the expectation to host two international sporting mega events: World Cup (2014) and the Olympics (2016). Analyzing media representations about the process of occupation, the goal of the research was to discover clues that help to think the impact of this political measure on the city and its inhabitants. It was possible to realize that, unlike what had been happening in recent decades, urban violence not presented as a matter of great interest to the newspapers, appearing only incidentally as occasional issues in a predominantly pacific context. Optimistic speech prevailed in relation to the city and its future. Accordingly, several matters reported on the success of the police operation, celebrating the replacement of police policy of confrontation by the actions of intelligence, which would have allowed the resumption of the Hill without a shot even being fired. Special emphasis was given to UPPs, systematically represented positively by the newspaper, residents, businessmen and specialists, who pointed out the project as a factor responsible for the wave of hope and optimism that surrounds the city. The UPP would be the element that would bring new meanings to the slums of the city. The aura of violence associated with slums was away, making disappear the fear that these spaces of the city historically cause in the general population. The UPP would be responsible for integrating slums in the city. The process of pacification of Rio slums, personified in the UPPs, would be the bridge that would allow the city to rediscover, to reinvent itself, retrieving the joy and self-esteem, leaving behind decades of pessimism and hopelessness. It was observed that during the search, the dynamics of media narratives broke with the previous pattern of representation of a violent city and has opted for an optimistic speech, albeit with occasional violent episodes.

Full textAbstract:
Because of the high levels of violence practiced by the Military Police of Rio de Janeiro State (Brazil), especially if its lethality is taken into consideration, the Pacifying Police Units - Unidades de Polícia Pacificadora (UPPs) in Portuguese - were created in 2008 to work in some favelas (slums or shanty towns) of the state’s capital, the city of Rio de Janeiro. This form of policing became the object of attention of several social scientists due to its apparently less violent action in these specific urban spaces, which are historically marked by a social stigma and constitute a special target for police action.
In this thesis, we analyze some of the research work that emphasized the UPPs’ characteristics as possibilities for a new and less violent police. It is argued that, despite the features that make the UPPs to be apparently less violent, it is necessary to take into account several other aspects that sociologically explain the police action in Rio de Janeiro and the UPPs.
The social construction of Brazilian citizenship and public space affects the way Brazilians build the notion of equality between individuals and social groups, relating it to similarity between themselves and accepting as natural the unequal treatment given by the state’s institutions. This legal and juridical culture, associated to the new economic and financial context that the city of Rio de Janeiro has been going through in the last years, refers to the necessity of state control over some favelas to be able to increase the value of such urban spaces, through land speculation, in order to achieve a surplus-value by implementing new economic and lucrative activities. This state policy is heavily based on “pacifying” the favelas through the politics of security, in which police play a major and important role.
Therefore, the thesis begins by offering an explanation of the Brazilian views of public space and citizenship, resorting to some social scientists studies that dealt with the specifics of those notions in Brazil. Then we elucidate how a documentary analysis was made explaining how the UPPs are understood in Brazil. Later, dissertating about the historical development of favelas and police in Rio de Janeiro, explaining the conjuncture in which the UPPs were implemented and how they are understood.
Yet, in our research, we consider that the UPPs are not breaking away from the paradigm of the Military Police of Rio de Janeiro State, but using a different practice to give continuity to a traditional function of policing (repression) and a process that one could call of “criminalization” of favelas.

Full textAbstract:
Prospective memory is colloquially known as “remembering to remember” and refers to forming an intention in the present time to fulfill at some point in the future. It has previously been studied within the context of executive functioning (i.e., purposive and goal directed behavior) and impulsive behaviors (e.g., gambling, risk seeking) within clinical populations. This study sought to further elucidate the relationships of impulsivity and executive functions on prospective memory in a non-clinical population. One hundred and nine undergraduates completed the UPPS-P impulsivity self-report questionnaire, three cognitive tasks measuring components of executive function, (i.e., planning, inhibition, and switching), and a Complex Prospective Memory Task that included Time- and Event-based cues. The UPPS-P and executive function tasks did not significantly predict the Complex Prospective Memory Task. However, executive function was found to be a significant predictor above and beyond that of impulsivity for a component of the Time-based prospective memory task. Implications of the results and future directions are discussed.

Fundação Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio de JaneiroEsta dissertação analisa o significado das Unidades de Polícia Pacificadora (UPP) enquanto técnica de controle incorporada ao espaço, usando como pano de fundo a fragmentação do tecido sociopolítico-espacial em curso na cidade do Rio de Janeiro que, junto com o biopoder Foucaultiano, propicia a formação das UPPs como novos dispositivos de segurança protetores da Raça Pura e assim, possam legitimar o poder do Estado. Além disso, a presente dissertação observa o significado da favela para a cidade do Rio de Janeiro e a regulação de poder dentro dela no período Pós-UPP, em especial, a forma de atuação dos principais agentes reguladores desse poder: traficantes de drogas armados; moradores e policiais. Finalmente, mede o grau de violência na Santa Marta antes e depois da UPP, usando os dados do Instituto de Segurança Pública (ISP) e entrevistas realizadas durante a pesquisa além de estabelecer alguns limites e possibilidades dessa nova política no que tange a prevenção da violência, usando três categorias de análise: redistributiva; institucionalista e culturalista.
This dissertation analyzes the meaning of Pacifying Police Units (UPP) as a control technique incorporated into space, using the backdrop of the sociopolitical tissue of space fragmentation underway in the city of Rio de Janeiro, which together with the Foucaltian bio-power, promotes the formation of UPP as new safety devices guards Purebred and thus can legitimize State power. Moreover, this paper points out the significance of the slum to the city of Rio de Janeiro and the regulation of power within during its post-UPP, in particular the form of performance of the main regulators of this power: armed drug traffickers, residents and police. Finally, it measures the degree of violence in Santa Marta before and after the UPP, using data from the Institute of Public Safety (ISP) and interviews conducted during the research to establish some limits and possibilities of this new policy regarding violence prevention, using three categories of analysis: redistributive; institutionalist and culturalist.

Mestrado em Desenvolvimento e Cooperação InternacionalEsta dissertação é uma reflexão acerca do modelo de segurança pública das Unidades de Polícia Pacificadora (UPPs) implementado na cidade do Rio de Janeiro a partir do ano de 2008, bem como uma análise dos impactos do referido modelo pacificador nos territórios e no quotidiano dos moradores das favelas cariocas "beneficiados" pelas UPPs. Com o intuito de romper com a imagem histórica de brutalidade e violência com que a atuação das forças de segurança do Rio de Janeiro nas favelas é associada, a Secretaria de Segurança do Estado do Rio de Janeiro desenvolveu um modelo de segurança pública baseado no conceito de polícia de proximidade que rompesse com o ciclo de violência e abandono para com os moradores das favelas. Todavia, devido a inúmeros problemas que serão aqui relatados, o modelo das UPPs se revelou uma política que pouco promoveu desenvolvimento social sustentável para as comunidades cariocas. Dessa forma, o objetivo desta dissertação é analisar os impactos negativos e as contradições existentes no programa das UPPs. Buscar-se-á responder se o referido modelo de segurança gerou desenvolvimento social sustentável para as favelas pacificadas ou se apenas contribuiu ainda mais para o reforço de um modelo de Estado que pune as populações mais pobres e desfavorecidas.
This dissertation is a reflection on the public safety model of the Pacifying Police Units (UPPs) implemented in the city of Rio de Janeiro from the year 2008 onwards, as well as an analysis of the impacts of the aforementioned pacifier model in the territories and daily life of the favelas residents "benefited" by the UPPs. In order to break with the historical image of brutality and violence with which the performance of the Rio de Janeiro security forces in the favelas is associated, the Rio de Janeiro State Security Secretariat developed a public safety model based on the concept of "proximity police" that aimed to break with the cycle of violence and abandonment towards the favelas. However, due to innumerous problems that will be reported here, the UPPs model has proved to be a policy that didn´t promoted significant social sustainable development for the Cariocas communities. Therefore, the objective of this dissertation is to analyze the negative impacts and contradictions in the UPPs program, aiming to understand whether the safety model implemented has generated social sustainable development for the pacified favelas or if ended up reinforcing a state model that punishes the poorest and most disadvantaged populations.

A presente dissertação possui como objetivo analisar quais impactos as políticas públicas têm a capacidade de produzir no que concerne à afirmação de direitos dentro de favelas situadas na cidade do Rio de Janeiro. Em especial, serão investigadas as consequências que o projeto das Unidades de Polícia Pacificadora (UPPs) estão trazendo para os locais contemplados com a medida. Embora seja anunciado como um grande sucesso, tal política pública apresenta resultados positivos no que diz respeito à redução de conflitos armados, porém é necessário refletir mais profundamente, questionando se o projeto repete uma lógica de pacificação da barbárie ou se pretende caminhar em outra direção.Para tal intento, o trabalho será dividido em três capítulos, que contarão com explanações e análises sobre os três nortes principais em que essa dissertação se apoia: as favelas, as políticas públicas e os direitos.
The current dissertation aims to analyze which are the impacts that public policies can produce in the affirmation of rights in the favelas located in the city of Rio de Janeiro. Especially, it will be investigated the consequences that the project called Unidades de Polícia Pacificadora (UPPs) are bringing to the places contemplated with the program. Even though it is announced as a great success, this public policy presents positive results in which concerns the reduction of firearms conflicts, but it is necessary to reflect more deeply, asking if the project repeats a logic of pacifying the chaos or if it intends to go on another direction. To this purpose, the work will be divided in three chapters, that will contain explanations and analyses about the three main basis in which this dissertation supports itself: the favelas, the public policies and the rights.

The botanical reserches were carried out ofter the methodics of general macrophytes investigation (by Katanskaja, 1981). It was used Brown-Blanquet (1964) or the so-called Zurich-Montpeljė school researches of floro and principles of classification, then too synthatical code to pick out associations (by Balevičienė, 1991; by Pott, 1992).
Macrophytes make up zones till 4 metres Width in the Mūša river. Longer areas in the river take up such associations: Potamogetonetum pectinati, Phragmitetum australis, Typhaetum angustifoliae, Phalaridetum arundinacea.
In order to clear up the arrangement of various macrophytes ecological groups and their forming associations, there were fulfilled 5 vegetation side-views in Mūša river.
68 species of macrophytes that belong to 26 families ant 49 genus were inventoried in the Mūša river. The following families distinguish the lorgest specific variety.

In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound. The result was a rule-based agent for notification of email, which primarily uses sound as interaction style.I fokus för mitt arbete står två begrepp, ljud och rummet samt att skapa en fusion mellan dem i ett gränssnitt.

Full textAbstract:
I vår allt mer globaliserade värld, som kännetecknas av ökad världshandel, integrerade ekonomier och landsgränser som suddas ut, krävs en allt större kunskap om hur länder skiljer sig åt. En marknad som på senare tid, då främst under 2000-talet, varit ledande när det gäller globalisering, teknologisk utveckling och inte minst inom byggsektorn är Dubai, Förenade Arabemiraten. Dubai har satsat enorma summor i turism och kommersialism, det i kombination med ett förmånligt skattesystem har gjort att många företag valt att söka sig till Dubai. Många av dem är tjänsteföretag och det går i linje med trenden att vi går mot en tjänsteekonomi. Denna bakgrund har lett uppsatsens författare till problemformuleringen: Hur påverkar kulturskillnader ett internationellt tjänsteföretags utformande av sin marknadsföring? Med utgångspunkt i marknadsförings- och kulturteorier är uppsatsens övergripande syfte att undersöka om det existerar skillnader och likheter i ett internationellt tjänsteföretags tillvägagångssätt att arbeta med marknadsföring i Sverige och i Dubai. Mer specifikt ska studien visa om det går att hänföra dessa likheter och skillnader till de kulturella differenser som råder länderna emellan. För att ge en ökad förståelse för motiv och orsaker till de strategiska val som respondenterna gör, kommer också en övergripande bild av marknadsföring i allmänhet i de respektive länderna att presenteras. Uppsatsen grundar sig på en kvalitativ ansats och intervjuer med tre anställda på UPS Dubai och två anställda på UPS Sverige. Slutsatserna av studien är att kultur har påverkan på utformandet av marknadsföringen. Faktorer som påverkar är bland annat hög- och lågkontext, språk, relationer, religion och osäkerhetsundvikande. Studien visar också marknadsföringsverktyg som påverkas, bland annat PR, annonsering, direktmarknadsföring och centralt producerad reklam.

Full textAbstract:
This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.
The UPS module consists of two parallel systems. Every system is built out of four parts. Part one consists of batteries and safety circuits, part two charges the batteries, partthree is a control unit, and part four delivers the voltage and current. The delivered voltage is 5 V and the current is 4 A.
Tests and verifications showed that the UPS module could supply a computer system with power for about one minute. The tests have been performed in a lab at AerotechTelub AB.
The UPS module is supposed to be mounted in a cassette. The cassette is then inserted in the computer system through a hole in the chassis. Thereby an opening of the computer system is avoided when the module is connected.

Full textAbstract:
Under de senaste åren har det skett en signifikant ökning av antalet nyregistrerade företag i Sverige och denna trend är tydlig även inom tillverkningsindustrin. Samtidigt går en betydande andel av start-ups inom tillverkningsindustri i konkurs inom tre år. Utmaningarna att i en uppskalningsprocess gå från idé till volymproduktion liknas ibland med att ta sig igenom ”Dödens Dal”. En vanligt förekommande strategi för att klara denna resa är att företagen beslutar om att lägga ut hela eller delar av produktionen till en kontraktstillverkare – ofta i utlandet. Detta får både konsekvenser för det enskilda företaget och för Sverige som nation i form av förlorade produktionstillfällen. Med ambitionen att identifiera vilka orsaker som står bakom dessa beslut samt undersöka nuläget på den svenska scenen för tillverkande start-ups har denna studie syftet att identifiera vilka utmaningar som start-ups inom hårdvaruproduktion upplever i samband med en produktionsuppskalning. Vidare undersöker studien hur dessa utmaningar hanteras samt vilket stöd som kan underlätta processen. Den metod som ligger som grund för studien har en kvalitativ ansats med en datainsamling baserad på ett större antal djupintervjuer. Både start-ups samt experter med dokumenterad erfarenhet på området har intervjuats. Studiens resultat visar att en central utmaning i uppskalningsprocessen är bristen på kunskap inom produktionsrelaterade frågor. Denna brist tydliggörs i flertalet av de övriga utmaningar som identifierats. Utmaningarna kategoriseras som finansiering, marknadsanalys och förstudie, produktionskompetens och att bygga team, prototyputveckling,processförståelse samt leverantörer och tillverkare. Dessa utmaningar hanteras med en viss variation företagen emellan. Studien ger ett antal förslag om hur ett stöd kan utformas föratt underlätta processen. Genom att utveckla en stödfunktion som kan sprida kunskap och fungera som ett bollplank i produktionsrelaterade frågor kan flertalet av dessa utmaningar hanteras. Vidare kan studenter från produktionstekniska program både utgöra ett stöd iutvecklingen samt en bas för en senare rekrytering. Avslutningsvis kan en tjänst som tydliggör ledig kapacitet och befintliga resurser hos aktörer som leverantörer och tillverkare bidra till att minska avståndet mellan start-up och aktör.During recent years Sweden has seen a significant increase in the number of newly registered companies. This trend is also evident in the manufacturing industry. Concurrently, a significant part of these manufacturing start-ups file for bankruptcy within three years. Due to the challenges the ramp-up process, completing this phase is sometimes compared to crossing “the Valley of Death”. A common strategy for the ramp-up process is to use a contract manufacturer for the company’s production. These contract manufacturers are often located abroad and this results in consequences for the company, as well as lost production opportunities for Sweden. This study aims at identifying the main reasons why companies decide to locate their production abroad and to examine the current situation on the Swedish start-up scene. Furthermore, the purpose of this study to identify the challenges that start-ups face inrelation to ramping up their hardware production. An examination of how start-ups can tackle these challenges and which support they need in order to facilitate the ramp-upprocesses will be made. The method used in this study has a qualitative approach where several in-depth interviews has been carried out in order to collect data. Both start-ups and experts with documented experience in the hardware production area has been interviewed. The result of this study shows that a central challenge in the ramp-up process is a lack of production-related knowledge. This deficit is evident in numerous of the additional challenges that has been identified. These challenges are categorised as finance, marketan alysis and pilot study, competence within production and building a team, prototype development, understanding of the production processes and supplier and manufacturers. These challenges were handled with some variation between the different companies. The study provides a number of solutions and suggestions of actions that can facilitate the rampup process for hardware start-ups. The development of a support function with the purpose to pass on knowledge and work as a sounding board in production-related questions will help start-ups tackle many of the identified challenges. Furthermore, engineering students may provide support in the development and later become a source for recruitment to the company. Finally, a service that clarifies available capacity in existing manufacturing and supplier resources would shorten the gap between the manufacturers or the suppliers andthe start-up.

High turnover among auditor assistants is a problem in the auditor profession. 61,7 % of young graduates economists have changed profession at least once during their first three years as employees (Hiltebeitel & Leauby, 2001), heavy workload in the auditing profession is considered to be a contributing factor (Axelsson, 2015). The main purpose of the study is to explain how students' views on the workload affects staff turnover among auditor assistants. In addition, the aim is to describe the expectations of a corresponding expectation gap between students and auditor assistants. In order to achieve the purpose of the study, behavioural theories such as Theory of Planned Behavior and Social Cognitive Theory have been adopted. Further, the Expectation Theory, Identity Theory, Theory of Professions and previous studies of the expectation gap and workload, stress and time pressure are used. The study is based on a combination method based on three interviews with auditor assistants, to develop an understanding of auditor assistants experience of the workload. Subsequently a questionnaire was sent to students with a total of 134 received answers. A short questionnaire with three questions similar to those sent out to students has also been sent to the auditor assistants, with a total of 43 received answers. The results shows that there is an expectation gap considering workload between students and auditor assistants. Further aspects have emerged as contributing factors to high staff turnover in the auditor profession, such as expectations for salary and work content.

Full textAbstract:
Agile methods for software development have become a well-known and trendy phenomenon since the turn of the millennium. Now, agile management methods are even starting to appear outside of the IT industry. We have interviewed and observed ten employees at a medium-sized system development company with the purpose to investigate how the meetings appear to the employees. We thereby aim to answer the question “What meaning does the stand-up meeting have for its participants?” The results are analyzed and discussed through Robert D. McPhee’s CCO-theory The Four Flows. We conclude that the meetings provide many potential benefits for coordinating activities, but that this depends upon the participants taking initiatives, focusing on relevant aspects of their own work and being familiar with the topics at hand. The respondents value the sense of overview and help in problem solving that the meetings provide. Still, what is being said during the meetings can sometimes be hard to understand. Participants generally have their membership negotiated in a way that includes them in the organization. However, new employees often experience initial comprehension difficulties. The daily stand-up is a place for organizational reflexive self-structuring mainly in the sense meetings enforces a sense of unity within the group. Institutional positioning however is not a predominant feature of this particular meeting routine. This study contributes to agile development communication in that it highlights the need for clarification regarding the goals of the daily stand-up-meetings, and that comprehensive difficulties should be addressed, not least for new employees.

Unternehmensgründungen sind durch ein hohes Maß an Unsicherheit und durch eine häufige Notwendigkeit externer Beratung gekennzeichnet. Daher ist Smart Capital, als eine spezielle Finanzierungsform, die Kapital und Informationsflüsse in Form von Betreuung und Beratung verbindet, von besonderer Bedeutung für junge Unternehmen. Der empirische Teil der Dissertation analysiert die verschiedenen Typen von Finanziers, die als potentielle Anbieter von Smart Capital angesehen werden sowie regionale Einflüsse auf Finanzierungsbeziehungen im Rahmen von Smart Capital. Des Weiteren wird die Rolle der öffentlichen Hand auf dem Markt für Smart Capital untersucht. Die Analysen machen deutlich, dass viele verschiedene Typen von Finanziers als Anbieter von Smart Capital in Deutschland agieren. Regionale Nähe zwischen dem Investor und den finanzierten Unternehmen spielt dabei jedoch nur eine untergeordnete Rolle. Eine regionale Unterversorgung an Smart Capital für junge Unternehmen ist unter diesem Aspekt nicht zu befürchten. Des Weiteren zeigen die Ergebnisse, dass öffentlich geförderte Anbieter von Smart Capital ihre Förderfunktion im Wesentlichen erfüllen.

The aim of this study was to investigate how counselors at BUP describe their experiences of mindfulness training in the workplace. Using a qualitative approach with semi-structured interviews, we interviewed six social workers employed as counselors and therapists at a child and youth psychiatric center in south Sweden. The analysis was based on Antonovsky’s salutogenic approach and three key elements of his Sense of Coherence concept: comprehensibility, manageability, and meaningfulness. The social workers’ descriptions indicate that they describe that mindfulness training has strengthened all three elements of Sense of Coherence, in their professional roles. This was expressed as follows: 1) A strengthened awareness of thoughts and mental states increased comprehensibility, experienced as a heightened sense of focus and structure in performing work tasks. 2) The ability to stay present and relax improved manageability as a tool to cope with stress in challenging situations. 3) Focusing on the positive aspects of the work and the appreciation of small steps of progress increased meaningfulness.

Mestrado em FinançasO objectivo deste estudo e inferir sobre os factores que conduzem a saida do mercado pelas start-ups, da perspectiva do individuo e da empresa. A literatura anterior tem-se apenas mais recentemente focado na saida como uma parte importante do ciclo economico e financeiro. No entanto, ha ainda um corpo estreito do pesquisa aplicado a pequenas empresas, ao contexto que integre fundador e start-up e a diferenciacao entre saida e morte ou falencia empresarial. Neste sentido, conduzimos uma analise multivariada para os diferentes acontecimentos: continuacao, liquidacao e venda, distinguindo entre saida voluntaria ou involuntaria de acordo com a performance da start-up, medida atraves do Altman s Z-Score. Inferimos sobre a influencia das caracteristicas do fundador e start-up no tipo de saida, usando dados financeiros de empresas e fundadores, que contem informacao unica e detalhada de 2004 a 2009. Os resultados obtidos indicam que a dimensao da start-up e equipa de fundadores, educacao do fundador, idade e genero masculino afectam positivamente a probabilidade de continuacao e venda e negativamente a de liquidacao. Os mais jovens fundadores tem mais probabilidade de abandonarem os seus empreendimentos enquanto os mais velho tem menores probabilidade de liquidacao. Consistente com literatura antecedente, as start-ups de maior tamanho e com fundadores com maior nivel de educacao tem menos probabilidade de se liquidarem.
The aim of this study is to infer the factors that lead to start-up exit from the individual and firm perspective. Previous literature has only more recently focused on exit as an important part of the business and economic cycle. However, there is still a thin body of research applied to small companies, a framework of both founder and start-up exit and the differentiation between venture exit and death/bankruptcy. Regarding this, we conduct a multinomial analysis for different outcomes: continuation, liquidation and sale and distinguish between voluntary and distress exit, based on venture performance., which is measured using Altman?s Z-Score. We infer on the influence of start-up and founder characteristics, on the type of exit, using Portuguese firm-level financial data with the matched employer-employee database that contains unique and detailed information on start-ups and founders from 2004 to 2009. Our results indicate that the size of the start-up and funding team, founder education, age and male gender positively impact the probability of continuation and sale and negatively impact liquidation. Younger founders are more likely to leave than to continue their ventures and older founders have lower odds of liquidation. Consistent with previous literature, bigger start-ups with more knowledgeable founders are less likely to liquidate.

Full textAbstract:
Efter egna observationer under våra VFU-perioder noterade vi förhöjda stressnivåer hos elever vid provtillfällen. Den här studien går därför ut på att undersöka hur lärare upplever elevers eventuellt förhöjda stressnivåer vid provtillfällen. Första frågeställningen handlar om hur lärare säger sig identifiera olika kategorier av stress och vilken som, enligt dem, är den mest problematiska för eleverna. Den andra frågeställningen ställer frågan om vad lärare säger sig ha för strategier när de upptäckt att elever får ett ökat stresspåslag. Slutligen kommer den sista frågan handla om hur lärare lyfter fram hur de kommunicerar om dessa prov till sina elever; före, under tiden och efteråt då resultatet ska presenteras. Vi har begränsat vår studie till att undersöka förhöjda stressnivåer vid nationella prov i matematik i årskurs 6. Studiens teoretiska utgångspunkter är att betrakta lärande i första hand från ett relationellt perspektiv och i andra hand ett didaktiskt perspektiv. Studien har utgått från semistrukturerade kvalitativa intervjuer med fyra lärare på två skolor i mellersta delarna av Sverige och dessa intervjuer har kategoriserats i tre olika nivåer; 1) Identifiering av olika kategorier av stress 2) Lärares strategier vid förhöjda stressnivåer 3) Kommunikation i syfte att reducera stresspåslag och/eller ångest Det empiriska material som samlats in har därefter analyserats och i diskussionen har det reflekterats över respondenternas svar i relation till den tidigare forskning som hänvisats till. Under dessa avsnitt redovisas resultatet och framhåller att det avgörande är vikten av att skapa positiva och nära relationer med sina elever men också vad lärare har för bemötande gentemot dem. Beroende på hur lärare väljer att agera och kommunicera inför och under tiden vid nationella prov i matematik i årskurs 6 samt presentation av slutresultatet påverkar det hur eleven mår mentalt i lärarens klassrum.

We study blow-ups and their relation to orders of vanishing in algebraic geometry. In particular, we study the exceptional divisor and the strict transform of a blow-up. We use the order of vanishing to measure the severity of singularities, and show that if we blow up a closed point on a hypersurface we obtain points of equal order above it.

Internet är ett globalt nätverk som förser en användare med ofantliga mängder information. Internet ger även användaren den unika möjligheten att själv publicera sin information utan någon form av kontroll. Den möjligheten har gjort att mycket missvisande och falsk information finns tillgänglig på Internet. Det är helt upp till användaren att försöka avgöra om informationen är sann, giltig och korrekt, det vill säga trovärdig, frågan är bara om användaren gör det?
Följande examensarbete har undersökt om en erfaren Internetanvändare utför någon form av källkritisk granskning, eller överhuvudtaget funderar över trovärdigheten hos information från webben. För att besvara ovanstående fråga har en enkätundersökning genomförts på olika datastudenter som studerar vid Högskolan i Skövde.
Slutsatserna från enkätundersökningen var att studenterna tänker ofta på om information från webben är trovärdig. De utför även stundtals någon form av källkritisk granskning på informationen. Dock ansåg många att de hade bristande kunskaper att utvärdera trovärdigheten hos informationen från webben.

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2011.ENGLISH ABSTRACT: The digital control of UPS systems has been difficult in the past due to a lack of DSP technology. It was for this reason not possible to establishing the necessary control to regulate the voltages and currents of the UPS systems. Recent advances in DSP technology have however provided the means of establishing central control of the UPS system as well as incorporating more complex closed-loop control algorithms by utilising a single floating-point DSP. Closed-loop control strategies are investigated and the central control of a line-interactive UPS is established in this study. Both the status of the physical system as well as various system parameters are controlled. The system both regulates and charges the storage batteries when the main utility supply is maintained. In the event that the utility fails, the converter instantaneously changes power flow towards the load with the aim of maintaining an uninterrupted voltage supply. Several closed-loop deadbeat based control strategies are investigated for the regulation of the inductor current. A solution for the regulation of the DC-link is also developed and implemented. Furthermore, an intensive study is done on the regulation of the voltage supplied to the load in the event that the utility supply fails. The investigation is initially approached by considering classical control theory. Although these control strategies provided sufficient results, a predictive strategy that is based on the physical conditions of the switching converter is finally investigated to establish closed loop control of the output voltage. This resulted in a high-bandwidth voltage controller capable of maintaining control under a wide-array of load conditions.
AFRIKAANSE OPSOMMING: Die digitale beheer van UPS stelsels was moeilik in the verlede as gevolg van 'n gebrek aan DSP tegnologie. Dit was vir hierdie rede nie moontlik om beheer te kon bewerkstelling ten einde die spannings and strome in the UPS stelsels te kon reguleer nie. Onlangse vordering in DSP tegnologie het egter dit moontlik gemaak om sentrale beheer van die UPS stelsel te bewerkstellig sowel as om meer komplekse geslote lus beheer algoritmes te inkorporeer met behulp van 'n enkele DSP. Geslote lus beheer strategiëe word ondersoek en die sentrale beheer van die line-interaktiewe UPS word bewerkstellig in hierdie studie. Beide die huidige toestand van die fisiese stelsel sowel as die verskeie parameters word beheer. Die stelsel beide laai en reguleer die batterye terwyl die hooftoevoer onderhou word. In die geval dat die hooftoevoer faal, word die omsetter se rigting van drywingsvloei verander om die las te voorsien van 'n ononderbroke spannings toevoer. Verskeie geslote-lus “deadbeat” beheer strategiëe word ondersoek vir die regulasie van die induktor stroom. 'n Oplossing vir die regulasie van die GS-koppervlak word ook ontwikkel en geïmplementeer. Verder word 'n intensiewe studie gedoen op regulasie van die spanning wat aan die las gevoer word in die geval dat die hooftoevoer faal. Hierdie ondersoek word aanvanklik benader deur klassieke beheer teorie te bestudeer. Alhoewel hierdie beheer strategiëe voldoene resultate gebied het, was 'n voorspel beheerstrategie gebaseer op die fisiese toestand van die omsetter finaal ondersoek. Die resultaat is 'n hoë-bandwydte spannings beheerder wat daartoe instaat is om beheer te handhaaf onder 'n verskeidenheid van lastoestande.

Full textAbstract:
Solar Power and Uninterruptible Power Supply (UPS) are two technologies that are growing rapidly. The demand for solar energy is mainly driven by the trend towards cheaper solar cells, making it economically profitable for a larger range of applications. However, solar power has yet to reach grid parity in many geographical areas, which makes ways to reduce the cost of solar power systems important. This thesis investigates the possibility and potential economic synergies of combining solar power with UPS systems, which have been previously researched only from a purely technical point of view. This thesis instead evaluates the hypothesis that a combined solar and UPS system might save additional costs compared to regular grid-tied systems, even in a stable power grid. The primary reason is that on-line UPS systems rectifies and inverts all electricity, which means that solar energy can be delivered to the DC part of the UPS system instead of an AC grid, avoiding the installation of additional inverters in the solar power system. The study is divided into three parts. The first part is a computer simulation using MATLAB, which has an explorative method and aims to simulate a combined system before experimenting physically with it. The second part consists of experiments on a physical prototype system based on basic UPS and solar power components. The third part is an economical assessment of investment costs and energy balances, comparing two separate systems (UPS and solar power separate) to one combined (UPS & solar power). The results from the prototype system show that adding solar power to an UPS system does not interfere with the UPS functionality in any major way, however for optimal performance some additional integration may be necessary. On the contrary, the additional power terminal that the solar panels constitute, can increase system performance during certain operational conditions. The result of the economic analysis shows that a combined system has potential for both a lower investment cost due to cheaper components and increased energy savings through lower conversion losses. The conclusion from the study is that a combined solar energy and UPS system is technically feasible. Furthermore, a combined system has clear economic advantages over two separate systems. This means that a combined system might be economically profitable even in situations where a separate system is not.Solenergi och avbrottsfri kraftförsörjning (UPS) är två tekniker som växer snabbt. Efterfrågan på solenergi ökar huvudsakligen på grund av den snabba utvecklingen mot billigare solceller, vilket lett till att solenergi blivit lönsamt i en större mängd applikationer. I många områden är solenergi dock fortfarande inte kostnadsmässigt konkurrenskraftigt jämfört med traditionella energikällor, vilket gör en fortsatt sänkning av kostnaderna för solenergi till en viktig fråga för solenergiindustrin. Detta examensarbete har som syfte att undersöka om det är tekniskt möjligt att kombinera solenergi med UPS-system samt potentialen för ekonomiska synergier med denna kombination. Tidigare forskning inom området har endast undersökt denna kombination från en rent teknisk synvinkel. Detta examensarbete driver istället hypotesen att ett kombinerat solenergi- och UPS-system kan leda till större kostnadsbesparingar jämfört med ett traditionellt nätanslutet solenergisystem, även i ett stabilt elnät som i Sverige. En on-line UPS skyddar en känslig last genom att kontinuerligt likrikta och sedan åter växelrikta inkommande ström för att därmed både isolera lasten från nätet samt höja strömkvalitén. I UPS-systemet finns därmed en likströmsdel dit solpanelerna direkt kan kopplas istället för att skicka den genererade solenergin ut på elnätet. Därmed undviks inköp och installation av sol-växelriktare i solenergisystemet. Studien är uppdelad i tre delar. Första delen är en datorsimulering i MATLAB och syftar till att explorativt undersöka det kombinerade systemet för en optimerad design innan fysiska experiment utförs. Den andra delen av studien utgörs av experiment på ett fysiskt prototypsystem baserat på ett principiellt UPS- och solenergisystem. Den tredje delen av studien är en ekonomisk analys av både investeringskostnader och energibalanser som jämför ett kombinerat system (UPS & sol) med två separata system (UPS & sol separat). Resultaten från prototypsystemet visar att påkopplandet av solceller i en principiell UPS har mycket låg påverkan på UPS-systemets funktionalitet, samt att solcellerna som en extra energikälla under vissa driftförhållanden kan ha en positiv påverkan på UPS-systemet. För optimal prestanda kan dock en viss integration av systemen krävas. Resultatet från den ekonomiska analysen visar att ett kombinerat system har potential att sänka investeringskostnaden genom billigare komponenter. Ett kombinerat system kan även leda till en högre energibesparing jämfört med ett nätanslutet solenergisystem eftersom konverteringsförlusterna i UPS-systemet sjunker i det kombinerade systemet. Slutsatsen av studierna är att ett kombinerat solenergi- och UPS-system är tekniskt möjligt. Dessutom finns betydande ekonomiska synergier med ett kombinerat system. Detta innebär att ett kombinerat system kan vara lönsamt även i fall där ett separat solelsystem inte är det.

Introduction: In the medical device space, a large proportion of the breakthrough inventions are developed by small firms that use private equity to bring their technologies from concept to varying stages of development. Medical Device companies spend a large proportion (11.4 % in 2002) of their sales on R&D, second only to Pharmaceutical companies. Smaller companies, in the meanwhile, spent 343 % of their sales in the same year'. [The Lewin Group (AdvaMed), 2004]. Private Equity financing is a critical factor that enables small start-ups to develop new technologies without a viable revenue stream to support the necessary R&D expenditure. In the medical device space, it has been noted that Venture Capital firms (VC's) use high risk capital to invest in early stage companies, and look for "exits" through either an Initial Public Offering (IPO) or through the sale of the start-up to an established firm. Corporations are also involved in varying degrees in early venture investments, through what is sometimes called Corporate Venture Capital (CVC), mainly for strategic reasons. Through CVC investments, some corporations hope, that as an insider, they would be able to judge better whether a particular company is a good target for acquisition. In this paper I review the exits through acquisition, from the perspective of venture backed start-ups, and hypothesize that factors related to the nature of investors, the type of investment, the impact of capital markets and the Intellectual Property of the company are associated with a higher exit valuation.
