The German version of the Satisfaction with Life Scale (SWLS): Psychometric properties, validity, and population-based norms.

Abstract: The Satisfaction with Life Scale (SWLS) is the most commonly used measure for life satisfaction. Although there are numerous studies confirming factorial validity, most studies on dimensionality are based on small samples. A controversial debate continues on the factorial invariance across different subgroups. The present study aimed to test psychometric properties, factorial structure, factorial invariance across age and gender, and to deliver population-based norms for the German general population from a large cross-sectional sample of 2519 subjects. Confirmatory factor analyses supported that the scale is one-factorial, even though indications of inhomogeneity of the scale have been detected. Both findings show invariance across the seven age groups and both genders. As indicators of the convergent validity, a positive correlation with social support and negative correlation with depressiveness was shown. Population-based norms are provided to support the application in the context of individual diagnostics.

Association between type D personality and prognosis in patients with cardiovascular diseases: a systematic review and meta-analysis.

Abstract: Since 1995, the association of type D personality and mortality in patients with cardiovascular diseases has been increasingly investigated. The aim of this meta-analysis was to integrate conflicting results and to examine possible moderators of this association. Prospective studies assessing type D personality and hard endpoints were selected and pooled in meta-analyses. Cardiovascular diagnosis, type and quality of adjustment, and publication date were examined in moderator analyses. Twelve studies on patients with cardiovascular diseases (N = 5,341) were included. Pooled crude and adjusted effects demonstrated a significant association of type D personality and hard endpoints (odds ratio (OR) of 2.28 (95% CI [1.43–3.62]), adjusted hazard ratio (HR) of 2.24 (95% CI [1.37–3.66])). The OR decreased over time (OR 5.02 to OR 1.54). There was no association in congestive heart failure patients. More recent methodologically sound studies suggest that early type D studies had overestimated the prognostic relevance.

Multi-criteria Optimization System for Decision Making in Construction Design and Management

Abstract: All new ideas and possible variants of decisions mustbe compared according to many criteria. The complexnature of decision-making requires practitioners to selectinvestment options based on a wider variety of policyconsiderations in addition to cost benefit analysis and puretechnical considerations. In economics and decisionmaking it is essential to be able to take into account theimpacts of cultural, social, moral, legislative, demographic,economic, environmental, governmental and technologicalchange, as well as changes in the business world oninternational, national, regional and local markets. Costbenefit analysis approach is a useful tool for investmentdecision-making from an economic perspective. Cautionsshould also be given to the methods of determining thevalue of social and local interests. Some socialexternalities, such as employment and regional economicimpacts, are generally omitted in current practices.Current practices tend to use cardinal or ordinal scales inmeasure in non-monetized criteria. The use of unreasonablemonetization methods in some cases has discredited costbenefit analysis in the eyes of decision makers and thepublic. It may be appropriate to consider these externalities inqualitative forms in a multi-criteria analysis. Multi-criteriadecision making is used in various areas of humanactivities. The Criteria can be qualitative and quantitative.They usually have different units of measurement anddiffer in optimization direction. The normalization aims atobtaining comparable scales of criteria values. In the newversion of the program LEVI 4 the normalization methodsare including vector, linear scale, non-linear and newlogarithmic techniques may be used. This softwareconsiders the main aspects of two-sided game problems.The following strategic principles are used: Wald's rule,Savage criterion, Hurwicz's rule, Laplace's rule, Bayes'srule and Hodges-Lehmann rule. This program isdemonstrated by considering a real case study involving 4evaluation criteria of the currently used external walls ofindividual residential buildings.
