Trends in the incidence of dementia: design and methods in the Alzheimer Cohorts Consortium.
Several studies have reported a decline in incidence of dementia which may have large implications for the projected burden of disease, and provide important guidance to preventive efforts. However, reports are conflicting or inconclusive with regard to the impact of gender and education with underlying causes of a presumed declining trend remaining largely unidentified. The Alzheimer Cohorts Consortium aggregates data from nine international population-based cohorts to determine changes in the incidence of dementia since 1990. We will employ Poisson regression models to calculate incidence rates in each cohort and Cox proportional hazard regression to compare 5-year cumulative hazards across study-specific epochs. Finally, we will meta-analyse changes per decade across cohorts, and repeat all analysis stratified by sex, education and APOE genotype. In all cohorts combined, there are data on almost 69,000 people at risk of dementia with the range of follow-up years between 2 and 27. The average age at baseline is similar across cohorts ranging between 72 and 77. Uniting a wide range of disease-specific and methodological expertise in research teams, the first analyses within the Alzheimer Cohorts Consortium are underway to tackle outstanding challenges in the assessment of time-trends in dementia occurrence

Kan konsumentförtroende anvÀndas för att prognostisera konsumtion i Sverige?
Making accurate predictions of private consumption expenditures is a difficult task. This thesis examines if consumer confidence can be used to forecast consumption. Using regression analysis, the link between consumer confidence and private consumption expenditures is analyzed for Sweden between the years 1994 and 2005. Two different models are estimated. In the first model consumption is regressed only on consumer confidence, while model two is extended to contain more variables. Model one explains about 25 percent of total private consumption expenditure. In the second model however, the incremental value of including consumer confidence in the regressions is low when other relevant variables are included. The main conclusion is that the value of including consumer confidence in prognosis models for private consumption expenditure is low. However, consumer confidence is available with a shorter publication lag than other economic variables, which means that it might still be of use, as a first indicator of upcoming changes and turning points in private consumption expenditures
Beteendevetare pÄ arbetsmarknaden : - En studie om den upplevda relationen mellan arbete och kompetenser
Arbetet Àr en intervjustudie med kompletterande dokumentstudie som syftar pÄ att utforska och belysa beteendevetares kompetenser och upplevelse av arbetsmarknaden. Examinerade beteendevetare frÄn Mittuniversitetet Sundsvall/HÀrnösand, som innehar anstÀllning, intervjuas för att skapa en bild av deras upplevelser av utbildning, kompetenser och arbetsmarknaden. Dokumentstudie av lÀrosÀtets utbildningsplaner och urval av relevanta kursplaner sker för att skapa komparativa data, samt för att utforska lÀrosÀtets kommunikation gÀllande programmet.Resultatet visar att de examinerade studenterna upplever en vÀxande efterfrÄgan av beteendevetare pÄ arbetsmarknaden. Vidare beskriver de examinerade studenterna en rad komplexa kompetenser som de upplever att de erhÄllit frÄn utbildningen. Som avslutande belysningspunkt ifrÄgasÀtts det om det finns nÄgon reell separation mellan att uppleva sig som bildad eller anstÀllningsbar. I fallet beteendevetare som erhÄllit examen frÄn Mittuniversitet finns det ingen upplevd skillnad mellan att vara bildad eller anstÀllningsbar, dÄ de tillfrÄgade individerna upplever sig sjÀlva som bildade och anstÀllningsbara.GodkÀnnande datum: 2019-06-05</p
Produktionsutveckling av bastuaggregatsavdelning
To invent an optimized product is a complicated process. This process is only half of the work. It is equally important to develop a production system that can produce the product in an  efficient and ergonomic way. After several evaluations of conceptual and detailed drawings a final idea has come to light.The idea intends, to the maximum extent, utilize the facility in a more efficient way through moving assembly lines and stations closer to the flock section and the stock for complete products. To make the production better, stations are placed in more logical places given the assignment they are supposed to accomplish. This improves the material flow radically. An important aspect of the improvement is that the three assembly lines no longer will be dependent of each other because they will have all the stations they need. The final drawing uses the facility more efficiently. This opens up a big area close to the steam section. This area can be used to increase the productivity for the section. At present time the steam section have a capacity of around 9,000 units annually

Ekonomisk policy och tillvÀxt i en transitionskontext: en studie av realsocialistiska lÀnder
Abstract During the last 15 years, the former âreally existing socialistâ economies have undertaken an extensive transition process. In this paper the development, measured as GDP growth, is analyzed using variables for economic policy. The analysis is both theoretical, taking as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones predicted by the theory. Furthermore, we discuss the specific transitional context that the âreally existing socialistâ economies represent. Finally, we discuss the potential policy implications of the paper; the importance of the sub discipline transition economics to economics; and feasible roads to further research
