Multiple hypothesis tests based On conditional differences in means

Many hypothesis tests are univariate tests and cannot cope with multiple hypothesis without an auxiliary procedure as e. g. the Bonferroni-Holm-procedure. At the same time, there is an urgent need for testing multiple hypothesis due to the very simple existing methods as the Bonferroni-correction or the Bonferroni-Holm-procedure, which suffers from a very small local significance level to detect statistical inferences or the drawback that logical and statistical dependencies among the test statistics are not used, whereby its detection is NP-hard. In honour of this occasion, we present a multiple hypothesis test for i.i.d. random variables based on conditional differences in means, which is capable to cope with multiple hypothesis and does not suffer on such drawbacks as the Bonferroni-correction or the Bonferroni-Holm-procedure. Thereby, the computation time can be neglected.     

Das TIMP-Inventar – Ein Beitrag zur ökonomischen Erfassung von Kern-Faktoren salutogener Führung

Occupational health management and science increasingly focus on the issue of health-promoting leadership. Meanwhile a lot of leadership behaviors have been identified that affect the health of employees. To measure them requires high costs. Therefore, the aim of this study is to identify core-factors of salutogenic leadership and to operationalize them for an efficient diagnosis. As an integrative work-related indicator of employees’ health sense of work coherence (Work-SoC) was chosen. In a deductive and inductive process the TIMP-inventory has been developed that enables the economic assessment of three leadership dimensions: Trust, Incident Management and Pressure. These factors explain with less items more variance of the Work-SoC construct than established general and health-related leadership scales of transformational leadership, consideration, social support, demanding leadership as well as positive and negative health behavior. That is why the TIMP-factors can be recognized as core-factors of health-promoting leadership.     

Bindung(en) in der Arbeitswelt

Vanishing or decreasing attachment is an indicator for changes within a work-oriented society. This particularly affects employment and our organizational commitment as well as bonds that are established in the context of professional relationships. This text provides a comparative analysis of two attachment-theoretical approaches that have developed simultaneously but independently from one another: commitment research into organizational psychology on the one hand and attachment theory based on developmental psychology on the other. Both are to be examined for their potential, their theoretical and empirical response to current dynamics in the world of work.     

Participatory Spaces of Mental Health Service User Organizations in the Post-deinstitutional Era: Mapping Roles and Challenges

By applying the concept of participatory spaces, this article maps and analyzes current research on mental health service user organizations (MHSUOs). We have analyzed research literature from 2006 to 2016 to examine how the role of and challenges facing MHSUOs are formulated in the post-deinstitutional era. The current situation is marked by MHSUOs parallel presence in invited, claimed and popular spaces for participation. The post-deinstitutional era is characterized by a shift in focus from gaining access to such participatory spaces, to critically examining the political opportunities available in these. We further argue that the dominance of psychiatry-specific spaces could prevent MHSUOs from fully exploring their potential for participation in broader social issues.     

Interkulturelles Coaching – eine komplexe,systemische Herausforderung

Intercultural coaching takes place in the highly complex reality of a globalized world. The coachee is an individual acting in the situational context of his assignment and his corporate culture. He has been socialized in his own culture, but is communicating and interacting with people who have been socialized in different cultures. In order to identify and solve problems, all three aspects (person, situation, culture) have to be considered. Some aspects may have more influence than others may, but they combine in a closely interwoven system. The authors outline the theoretical background of intercultural coaching and illustrate the process with case studies.     

Why does class matter? Policy attitudes,mechanisms, and the case of the Nordic countries

In most democracies, classes tend to vary with respect to an array of attitudes and behaviours, and differences are large within a number of European polities. What mechanisms lie behind these differences? Do they relate primarily to individuals’ material interests, as assumed by traditional class theories, or instead, to socialization and self-selection factors? This paper seeks to extend theory and research through an analysis of mechanisms behind class differences in policy attitudes. Our focus is on the Nordic countries, where class differences are extensive and well-documented in past scholarship. We take advantage of high-quality European Social Survey data for Denmark, Finland, Norway, and Sweden. Analyzing three policy arenas and the 9-category European Socio-economic Classification scheme (ESeC), we find evidence that class-related factors help to explain cleavages in attitudes. Comparisons with the more detailed, 103-category International Standard Classification of Occupation scheme (ISCO) suggest that these factors explain less “micro-class” occupational variation. Results shed new light on mechanisms behind class differences, and the empirical foundations of established class theories. These and other implications are discussed in the conclusion.     

Tractor accidents in Swedish traffic

The objective of this study is to reach a better understanding of accidents on Swedish roads involving tractors and to suggest ways of preventing them. In an earlier study we analyzed police-reported fatal accidents and accidents that led to physical injuries from 1992 to 2005. During each year of this period, tractors were involved in 128 traffic accidents on average, an average of 7 people were killed, 44 sustained serious injuries, and 143 sustained slight injuries. The number of fatalities in these tractor accidents was about 1.3% of all deaths in traffic accidents in Sweden. Cars were most often involved in the tractor accidents (58%) and 15% were single vehicle accidents. The mean age of the tractor driver involved was 39.8 years and young drivers (15-24 years) were overrepresented (30%). We are now increasing the data collected with the years 2006-2010 in order to study the changes in the number of accidents. Special attention will be given to the younger drivers and to single vehicle accidents. Based on the results we aim to develop suggestions for reducing road accidents, e.g. including measures for making farm vehicles more visible and improvement of the training provided at driving schools.     

The relevance of temporal iconicity with instruction manuals for elderly users

Gerontolinguistic obtains a growing importance with the increase of elderly users due to Demographic Change. Since acceptance and ease of use of supportive systems for elderly, such as "E-Nursing-Assistants", are highly dependent on the age suitable design of readable instructions, an age-appropriate linguistic concept is of high value for usability. There has been only little research on the relevance of foreign words, signal words, textual arrangement, optical accentuation of key terms and temporal iconicity concerning older users. Thus, an efficient design of age suitable manual instructions within a medical context still remains to be done. The objective of this research was to evaluate the relevance of the previously mentioned factors in the context of written instructions. For this, an empirical survey was designed which was given to 45 study participants. The subjects of the experiment were given 4x3 instructions after a pretest questionnaire. The aim was to execute these instructions as correctly and quickly as possible. Furthermore the instructions were rated regarding comprehensibility with a retrospective questionnaire.
