Lönar sig Supply Chain Management för mindre företag?

Purpose - To analyze the relationship between supply chain management maturity, supply chain performance and financial performance in small and medium-sized enterprises (SME:s).Design/methodology/approach - The data comprises 15 SME:s that participated in a local logistic study in Gävleborgs län. The levels of supply chain mature within these firms were based upon an interview study and the financial performance of the firms was then examined using financial reports-based data.Findings -The results of this study indicate that there is a strong relationship between SCM maturity and SC performance in SMEs, some relationships between SCM maturity and financial performance, as well as some relationships between SC performance and financial performance. This means that if firms use maturity indicators in the SCOR areas to improve their processes, they will most likely achieve a positive effect on supply chain performance and probably also on financial performance. The result implies that the supply chain maturities in these firms are higher than expected with no one at the adHoc level.While this study is based on a rather small number of participating firms, it would be valuable to further test the significance of the indicated correlations between SCM maturity and performance in a large-scale survey.Research limitations/Implications - The research is an attempt to understand supply chain maturity and it´s implication on financial performance. Developing supply chain maturity is an opportunity for a company to gain superior performance.

Självkänsla och bekräftelse på sociala medier : En kvantitativ enkätundersökning om självkänsla, bekräftelse på Instagram och skillnaden mellan män och kvinnor

Skapande av organisationskunskap i små, unga forskningsintensiva företag : En studie av tre företag i Uppsala

Because of among other things the globalization and a focus on core competencies knowledge has become very important for the companies of today, especially for research-intensive companies. The problem is that the companies become more sensitive to how knowledge is created and spread, that is, how organizational knowledge is created. Especially sensitive are companies who are small, young and research-intensive. The purpose with this thesis is to explore how organizational knowledge is created in small, young and research intensive companies.The theory is based on a five-phase model of organizational knowledge creation and four modes of knowledge conversion described by Nonaka and Takeuchi (1995). These concepts constitute the foundation of the analytical model used in the thesis.The study is carried out by qualitative, highly structured interviews with low standardization.

Deep Green i oceana strömmar - en konceptstudie

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

Studiens syfte var att validera en modifierad svensk översättningav självskattningsskalan som mäter anhedoni, Snaith-Hamilton PleasureScale. Syftet var också att utforska relationen mellan anhedoni och fatigue,stress, mental trötthet respektive dagtrötthet. Studiens deltagare, 60universitetsstudenter, utgjorde en icke-klinisk grupp som rekryterades medbekvämlighetsurval. Den modifierade svenska översättningen av Snaith-Hamilton Pleasure Scale uppvisade god intern konsistens, samt god konvergentvaliditet vid korrelation med anhedonirelaterade subskalor i Beck DepressionInventory. Vidare uppvisade Snaith-Hamilton Pleasure Scale starkapositiva samband med Fatigue Impact Scale respektive Mental FatigueScale, men inte med The Perceived Stress Scale respektive Epworth SleepinessScale.

Hur barn i årkurs 3 uppfattar syftet med Nationella provet

This is a study of the national test in 3rd grade. The national test is obligatory and is conducted in 5th and 9th grade, but since the spring of 2009 the tests also become mandatory in 3rd grade. The case study of this research is to find out how children in 3rd grade perceive the purpose of the national test. The survey should also clarify how students think and feel about the national test, and how they feel before the national test and after they have finished writing the test. Has the test positive or negative influence on children? The survey will also show how much teachers clarify what the significance of the national test is for the students.

Erfarenhetsåterföring :  

This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..

Agilt - men agilt nog?

This paper aims to investigate whether a small organization with small development teams can find a value in leaving a functioning development process to follow a formal systems development methodology, if these organizations can find support in an agile systems development method and in such case the method needs to be adjusted according to the organizations unique conditions.A traditional plan-driven system development methodology includes a number of phases that are carried out sequentially and a completed phase can basically not be resumed. All requirements are specified at the beginning of a project and at the end of the project only one delivery of software take place. This can cause difficulties in for example dealing with changing requirements. Agile system development methods intend to deal with changing requirements and to enable continuous delivery of valuable, working software.In this paper, both the traditional plan-driven methods and agile methods will be explained. Research methodology and existing system development theories will be discussed and a company where the study has been conducted will be presented.

Humorstilar, Emotionell Perception och Kön ? Vem skrattar mest och vem skrattar sist?

The main aim of this research was to investigate four humour styles, affiliative, self-enhancing, aggressive, and self-defeating humour, and compare these with emotional perception. Forty-eight persons took part in the research, 27 women and 21 men living in the southern part of Sweden. Two humour tests were used: the Humour Scale Questionnaire ? HSQ, with 32 items, and a newly composed video test, assembled after pilot testing from 26 video clips, the Humour Video Questionnaire ? HVQ. To measure perception and interpretation of emotion, the revised version of the ?Reading the Mind in the Eyes? Test was used.

Ny betygsskala- för elevernas bästa?

This essay is a study of the government bills for a new grading scale in the Swedish schools. There have been many complaints about the current grading scale and the main problem seems to be that teachers are interpreting the criteria for certificates differently. There are two major challenges for Swedish teachers, one is how to interpret the criteria for certificates, the other one is the equality problem , students can not be sure of that two different teachers would give the same grades. The main point of the essay is to try to find out whether the new grading scale will solve this problem. To my help I have made an analysis of the bills of the Swedish government for the new grading scale.

Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB

The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

Uthållig sanitet : en förstudie i staden Picota, Peru

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.

Förutsättningarna för ett parallellt generation IV system vid svensk nybyggnation av kärnkraft.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.
