Entreprenörers levnadsstandard: en fråga om personlighet : Kvantitativ undersökning av den materiella levnadsstandarden hos egenföretagare i Sverige

Earlier quantitative entrepreneurial studies with a focus on poverty rate has centred their arguments and analyses entirely on income differences which has resulted in a high poverty rate among self-employed. Their results shows that variables such as age, gender, hours of labour and structure of the household significantly affect the poverty rate among self-employed. In this study we aim the focus on material living standards instead of income differences, thus using a more representative approach while studying entrepreneurial poverty. The purpose of the study was to examine how personality traits (big five) affect the material living standards among the self-employed in Sweden, using a group of employed as a control group. Variables earlier known to affect the poverty risk among self-employed where used as control variables together with education and household income.

En studie om studenters användning av vänlistor på Facebook

Friend lists allow Facebook users to group their friends and may be used to share certain information only with those in a specific list. This function has been around for several years, but has never gained any particular popularity among users, most of whom probably did not know it even existed a couple of years ago. In the fall of 2011, however, the function was updated and made more visible on the site.There are several possible uses of friend lists, such as privacy control, filtering of the news feed, self-presentation and targeted information sharing. This paper aims to investigate the extent to which friend lists are used by students today, as well as why students actually use their lists, i.e. for what purposes.Judging from the results of this study in comparison with earlier research, there seems to have been a somewhat recent increase in the awareness of the fact that friend lists actually do exist, but still most users tend not to utilize them.

Styrmedel för att hantera kreditrisk: En fallstudie av Handelsbanken Sergel

The Swedish bank Handelsbanken has, according to their own way of measuring, been more successful than a weighted average of their competitors during the last 38 years. They have also handled the recent financial crisis, as well as the one in the 1990´s, better than most other banks. This paper studies their management control system at branch level in order to identify the controls which have been enforced to ensure that a low risk level is retained in the lending. The controls that have been identified are; (1) A decentralized organization with the offices as profit centers where the manager has restrictions regarding risk level and the results are measured as K/I (cost/revenue). (2) The absence of bonuses and individual follow-up regarding performance measurement.

Link QualityControl (LQC) i GPRS/EGPRS

This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected.

Lean control. What's it all about? En undersökning av kontrollmekanismer vid lean.

Bakgrund och problem: Dagens företag verkar i en osäker och dynamisk miljö där marknaden ställer allt högre krav på snabba förändringar och anpassningar till kundernas behov. För att möta denna dynamiska omgivning har en rad nya produktionsfilosofier introducerats. En av dessa som fått stor uppmärksamhet och vars användning ökat är lean.Under senare år har det kommit att riktas stark kritik mot tillämpningen av traditionell ekonomistyrning och att denna kan vara skadlig vid tillämpningen vid lean. Andra forskare tar det steget längre och ställer sig frågan om det finns någon plats för ekonomistyrningen vid operationella koncept.Som ett svar på ovanstående kritik introducerades lean accounting, ett ämne som fortfarande är hårt debatterat inom managementlitteraturen. Andra forskare skiljer här på lean accounting och lean control, där lean control fokuserar på output, behavioral samt social control.

Modell av en synkronmaskin för PSCAD/EMTDC med magnetisk mättning i d-led och elektriskt gränssnitt för fältmatare

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Car Lock Improved by Configurable Key

When a car owner want to lock or unlock his or her car today, it?s preferable done by using aremote control. The system is really comfortable when the car owner is using the remote.A problem arises if a thief gets the remote.The thief doesn?t have to know where the car is parked, an approximate estimation where thecar is parked is enough.For instance, it?s enough to know which car park the car is parked in. If the thief knows that,he/she can repeatedly activate the remote control while looking for a car indicating with lightsand sounds.Because of the fact that a car usually indicates that it has been unlocked by making a shortsound indication, there will be no problem finding the car.The purpose with this project is to make a prototype which makes it harder for a thief to findthe car.

Skuldlättnader som vapen i kampen mot korruption? : Om hur HIPC-initiativet påverkar korruptionsgraden i berörda länder

This paper examines how debt cancellation, given under the HIPC-initiative, has affected corruption over the period 2000-2006. The examination is foremost interesting due to earlier research showing that high corruption leads to unequal distribution of economic resources. This, combined with the objective of the HIPC initiative to reduce poverty, indicates that combating corruption must be successful in order to fulfill the goals of the initiative. A linear regression shows that countries that have benefited from the HIPC-initiative indeed have a lower corruption than other countries. A panel-data analysis shows on the other hand that no effect on corruption due to debt cancellation or reforms undertaken in the program can be confirmed..

En diktaturs väg in i Informationssamhället Kina och World Summit on the Information Society

This masters thesis investigates the relation between China and the Information Society as it is manifested in the UN conference the World Summit on the Information Society WSIS. The first phase of this two-phase conference took place in Geneva 10-12 December 2003, with two documents, Declaration of principles DP and Plan of action PA, as main results. The information policy is central to an authoritarian rule in its efforts to keep control over the national identity. The thesis investigates the impact that the information revolution and Internet might have on the Chinese national identity through the acceptance of DP and PA in various aspects. With the use of the information science theories by Manuel Castells and Frank Webster, the vision of WSIS was compared with the Chinese information policy.

Livsmedelssäkerhet för skolor, förskolor och äldreomsorg i Varbergs kommun; HACCP för tillagnings- och mottagningskök

One of the main objectives of all food production is to produce foods that can safely beconsumed without fear of being sick. Despite this hundreds of people are affected in Sweden offood poisoning almost every day. Most cases are caused by a small group of so-called pathogenicmicroorganisms. The most frequently affected are the small children, the elderly, persons withreduced resistance and pregnant. The reasons behind the food poisoning are often ignorance andlack of food hygiene.

Kan företag tvingas till tillväxt?

The purpose with this disertation is to find if there are selected factors which can force companies to grow. We have chosen five factors which we think can force the companies; market, strategy, profitability, demographic and institutional factors. We want to examine if there are differences between small and larger companies, and if there are differences between the lines of business.The intention to growth is also influenced by different factors. The organization and the board have an effect on the development. There are also factors that can obstruct the growth, for example control.

Utvärdering av effektstyrningssystemet EnergiDirigent® ur ett miljöperspektiv

Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.

Effekter av predationsrisk på sånglärkors (Alauda arvensis) habitatval på åkermark

Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.
