Webbplatsen - Vad spelar den för roll?: En studie av webbplatsens betydelse för traditionella tjänsteföretag.

Abstract: The purpose of this thesis is to study the importance of having a website for traditional service companies as well as the factors that might influence its importance. This is done by answering three research questions that all contribute to the answer of the main purpose. A qualitative study has been performed including eight interviews with respondents from eight different service companies presenting four different types of businesses. The empirical findings of the study are analyzed with the help of the theoretical frame of references in order to identify the most interesting conclusions. The results of the thesis state that the main purpose of the website among the studied companies is to rationalize and save costs.

Intra-individuell variabilitet i nära transfer : Om åldersrelaterade skillnader i intra-individuell variabilitet i prestation och effekten av kognitiv träning

Syftet med denna studie var att undersöka om träning av exekutiva funktioner kan påverka den intra-individuella variabiliteten (IIV) i reaktionstid hos unga vuxna och äldre. De 29 yngre och 30 äldre deltagarna i studien delades upp i två grupper, en träningsgrupp som gick igenom 15 sessioner av träning i exekutiv funktion och en kontrollgrupp som endast deltog vid pre- och posttestning. I träningsbatteriet tränades de exekutiva funktionerna uppdatering, skiftning och inhibering i enlighet med det teoretiska ramverk om exekutiv funktion som skapats av Miyake (2000). I studiens pre- och postmätningar användes reaktionstidsdata från tre tester: Serial Reaction Time (SRT), Flanker och Alternating Runs. Dessa tester skiljde sig från de som användes i träningsbatteriet.

Alternativ till fortsatt elektrisk generering i Olidan

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Det finns elever vars resurser inte tas om hand : 24 elever på IV-programmet och deras skolkarriär

Årligen slutar 30 procent av eleverna gymnasieskolan utan betygsbehörighet. På individuella program (IV) är siffran 85 procent. För att kartlägga skolsituationen för en elevgrupp på IV-programmet intervjuades 24 elever. Utöver detta gjordes en kognitiv bedömning samt en självskattning av upplevd psykisk hälsa. Huvuddelen av eleverna presterade på en ojämn kognitiv nivå, inom normalvariationen.

Den organisatoriska strukturens påverkan på Agile i praktiken

Agile as an idea was created in 2001 through the Agile Manifesto with focus on social relationships, communication and flexibility. This was a reaction to the traditional, hierarchical organization with the goal of restoring balance within organizations in the IT business. Today we can see a transit of Agile from the IT-industry to other industries and areas, such as HRM.There is a challenge in attempting to traditionally control a social idea such as Agile, and there is a lack of empirical studies of the organizational context and its effect on the interpretation of Agile in practice. This study is an attempt to connect Agile to the science of business administration.The purpose with this study is therefore to research the organizational contexts effects on the interpretation of Agile in practice, within IT and HRM. Where Agile is established or well known.To fulfill our purpose we chose social constructivism as our scientifically approach, and conducted 12 in-depth interviews.

Biogas : En systemanalys av Solna Stads matavfallsprocess

Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.

RCC-Jordfelsskydd, mätmodul för övertonsanalys

The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.

När en förälder dör : En studie av tre fiktiva tonåringars identitetsutveckling och coping vid förlust av en förälder

The purpose of this study is to examine how the identity of teenagers is affected by the loss of a parent as well as what coping strategies support identity development. The reactions the teenagers exhibit, in such circumstances, will also be examined. To accomplish this,  a theory package was created, comprising theories in developmental psychology, identity work, coping and theory of grief reactions of children and teenagers. This package provided a broad perspective, which facilitated the analysis. Furthermore, it made it easier to address the purpose and the issue of the analysis.

"Säg mig vad du äter och jag ska säga vem du är" : En kvantitativ studie om efterfrågan av hälsosamma livsmedel

Obesity and overweight are today classified as one of the largest epidemics in the Western world and is threaten a large part of the population. As a reaction to this a major health trend has emerged in recent decades. Every day consumers are exposed to information from the media about what is healthy or unhealthy to eat and the recommendations change frequently.There is great interest in healthy food on the Swedish food market, but still healthy foods only represents a small proportion of the total food sales. The essay examines the gap between the current and potential demand for healthy food and if it can be explained by any of the following factors: lack of information, price, taste or cognitive behavioral.To study these questions a quantitative method have been used and 213 questionnaires were collected. The intention is to draw general conclusions about the entire population.

Mode bakom kulisserna: - Praktik och förutsättningar för snabbhet och flexibilitet i inköp

Purpose: To explore the purchasing function, mainly the supplier selection activities, in the fast fashion apparel industry. The purpose is 1) to explore the criteria associated with supplier selection for fashion products, and 2) to analyze the purchasing activities in order to find characteristics and trends which are considered to be strategic for the buying company. Method: The empirics consist of qualitative interviews with employees with responsibility for the companies' purchasing activities, as well as information gathered from articles, annual reports, and company websites. Result: The study indicates that qualitative criterias have increased in importance, and have become an important part of supplier selection for fashion goods. A number of characteristics where identified as important for purchasing fashion goods, which can affect choice of supplier; examples are increased collaboration, increased re-buys and increased use of logistics services.

Utsöndring av klamydia från kliniskt friska katter :

Blood samples from 44 clinically healthy cats were analysed for the presence of antibodies to Chlamydophila felis. As we wanted to investigate if the antibody titre of clinically healthy cats correlates to shedding of chlamydia, conjunctival and vaginal or preputial swabs respectively, were taken and analysed with rtPCR (real-time polymerase chain reaction) for the presence of chlamydia DNA. Furthermore, to investigate possible epidemiological factors connected with asymptomatic cats infected with chlamydia and to see if there were any indications that chlamydiosis can cause reproductive problems, the owners of the cats were asked questions regarding this. Sixty-one per cent (27 of 44) of the cats were seropositive. Three of these (11 %) had the highest antibody titre (1:1600).

Konsumtionens klimatpåverkan : En jämförande studie mellan två socioekonomiskt skilda bostadsområden, Araby och Söder i Växjö

The world is in a stage of climate crisis where the average temperature is rising, with consequences such as, melting ice sheets, increasing sea levels, and floods. The climate panel of the UN, IPCC, has stated that this is a reaction of anthropogenic emissions of greenhouse gases. The most important gas is carbon dioxide, which contributes with 80 per cent to the on going climate crisis.The increasing emissions of carbon dioxide are connected to human consumption patterns. This puts pressure on the earth, as humans demand more and more resources. Today the earth needs one and a half year to regenerate the resources humans? demand of it, by the year 2030 we will need two planets in order to cope with this increasing demand of resources.At a global level it is established that richer countries have a stronger consumption pattern than poorer, and thus generate higher levels of carbon dioxide emissions.

Solenergisystem i Hammarby Sjöstad

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.

Dold marknadsförings effektivitet i sociala media

In this paper the authors examine three questions: 1) Is stealth marketing messages posing as status updates on Facebook a more effective way of advertising than traditional web banners? 2) What impact has learning about stealth marketing practices in social media on consumer attitude and post purchase behaviour? And finally 3) Will different generations respond differently to these questions?Our findings show that stealth marketing in social media is not more effective than traditional web banners. Furthermore, the result indicates that when consumers find out about stealth marketing practices it will have a negative impact on future purchase intensions and brand image. Most consumers will also have strong feelings of being deceived, which could instigate harmful post purchase behaviour such as negative word-of-mouth and possibly, based on some earlier cases, boycotts.The result of our research shows that the brand perceptions and future purchase intentions of Generation Y, persons between 18 and 30 years of age, are affected in a less negative way than the brand perceptions and future purchase intentions of older generations when finding out about stealth marketing practices in social media. However Generation Y:s reaction is still negative and they do consider traditional web banners to be more credible than status updates on Facebook.
