Media och näringslivet: En studie om hur mediedrev bör hanteras enligt informationschefer och presschefer

Media has power and impact. It is therefore important for managers to be able to handle media storms when they arise. If not, the brand can be affected negatively. It is managers who should learn to handle media storms because the managers constitute an important part of the external face of the company. Because it is managers who should learn to handle media storms it is interesting to study how media storms should be handled from a theoretical management-perspective.

Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

Automatisk Cykelväxel : Förstudie och datainsamling

A fauna passage is a way for animals to cross roads separated from the traffic. In Sweden, there are an unknown number of passages with different functions and appearances. These passages would, with the question ?Which fauna passages can be found in Sweden, and how well do they work?? as a base, be compiled in a comparable way. This would be done with a number of questions asked to the different regions of Vägverket.

Skotares bränsleförbrukning :

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

Strategisk kommunikation inom franchising, en fallstudie av Gallerix

AbstractTitle: Strategic Communication within franchising, a case study of GallerixNumber of pages: 60 (65 with enclosures)Author: Charlotta Babington ThorszeliusCourse: Media and Communication DPeriod: Spring 2008University: Division of Media and Communication, Department of Information Science, Uppsala University, SwedenPurpose/Aim: To find out, by doing a case study, how communication between the two parties in a franchising relationship works, and how communication can strengthen the concept and brand. By analysing the communication, identify strengths and weaknesses and make suggestions for improvement.Material/Method: Qualitative method by using interviewsMain results: The understanding of the concept and the relationship between franchiser and franchisees are vital for the success of the franchising chain. The main internal communication channel today is the Intranet, and more personal contacts and meetings are requested. The yearly meetings are appreciated by the franchisees, but the content of the meetings are of varied quality. The chains value words, which are important for how the brand is perceived by the customer, are slightly different from how the franchiser and the franchisees sees them.

Ute och cyklar? : på jakt efter en metod att mäta upplevelse

Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

Äldre boksamlingar på kommunala bibliotek resurs eller belastning?

Care and solicitude about Swedish documentary heritage has varied substantially throughout the years. The main purpose of this essay has been to investigate what efforts have been made to preserve rare book collections at public libraries. These cultural policies have been studied from both a national as well as local perspective. What we have tried to explore can be condensed into three questions: What national initiatives have been taken in the past century to preserve the municipal documentary heritage?What initiatives have been taken in the past century to preserve thedocumentary heritage of what is presently the municipality of Jönköping? What value do rare book collections at public libraries represent? The results indicate few national efforts were initially made to preserve rare book collections in the timeframe we studied.

Vilken påverkan har arbetsmarknadens institutioner på arbetslöshet? : en ekonometrisk jämförande studie av kapitalstock och arbetsmarknadsinstitutioner

This papers? objective is to examine the effects that labour market institutions (LMI) have on the unemployment in the short- and the medium run throughout the new Keynesian NAIRU theory, but also to make a comparison with the postkeynesian capital stocks? effect on the unemployment. Thus, it is this papers? main objective to study the economic effects that LMI, capital accumulation and varied macroeconomic shocks might have on unemployment. The paper uses econometric regression models as a methodological benchmark in order to estimate each independent variable?s level of significance and to approximate the effect each have on the dependent variable.

A comparison of transporters? paddle use when unloading pigs at slaughter

Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.

The reason for this islack of knowledge in this area and its irrelevance to the mechanical engineering education insuch..

Värdet av skapande i förskolan : En studie om pedagogers förhållande till skapande verksamhet i Stockholm och i Tornedalen

The purpose of this study was to investigate how preschool pedagogues in Stockholm and in Tornedalen speak about and relate to creative activities. By qualitative interviews in two geographically distant areas, one minority culture and one majority culture, I have collected information from six pedagogues, three in each area. Values in, and the significance of culture in creative activities have been the main focus. From this study I conclude that all pedagogues agreed upon the creative activity having an extensive role in the preschool work. The role of the individual pedagogue within the creative activity is multiple and dependent on where, when and how the activity is carried out.

Förekomsten av den genetiska varianten laktapersistens hos neolitiska grupper från Öland : The contribution of the genetic variant Lactase persistence among Neolithic people from the Baltic island Öland in Sweden

This study deals with the contribution of the genetic variant lactase persistence among Neolithic people from the Baltic Island Öland. Skeletal remains from twelve individuals went through DNA sequencing in order to find the mutation that allows adult individuals to digest milk sugar. The twelve individuals were chosen from two different Neolithic sites, where the archaeological and isotopic data suggest that the individuals from Köpingsvik were hunters and gatherers and the individuals from Resmo were early farmers. The individuals with the genetic variant lactase persistence can be described with selection and genetic flow.  Only five individuals produced results and the mutation was found in two of the subjects. All the individuals who were successfully sequenced came from Resmo, whereasno individuals from Köpingsvik yielded any results.

Undersökning av vissa beläggningars påverkan på antenners effektivitet i tågmiljö

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Stress i omsorgens vardag : Personliga assistenters och boendestödjares upplevelser och hantering av stress, samt hur deras stress kan påverka brukarrelationen.

The focus of our study was to examine personal assistants and group home assistants experiences of stress at work, how they cope with stress and how it affects the relationship with the care recipient. The study is made out of a qualitative frame and based on interviews with two personal assistants and four group home assistants. Our theoretical perspectives consist of Aaron Antonovsky?s SOC theory, Richard Lazarus theory about coping and also sociologist Johan Asplund?s theory about social interaction. The result indicates that the experiences of stress are individual and varied among the participants while the presence of stress at work is a shared apprehension.
