Popular sovereignty and the historical origin of the social movement

This article seeks to explain why the social movement had its historical origin in the 1760s. It argues that the rise of the social movement as a particular form of political action was closely linked to a new interpretation of sovereignty that emerged within eighteenth century British politics. This interpretation, which drew inspiration from Jean-Jacques Rousseau??s social contract thinking, not only resonated with the radicalism of John Wilkes and his followers?? struggle to promote civil liberties to Englishmen of all classes, it also spurred a transformation of the repertoire of popular contention. The article traces the evolution of the concept of sovereignty in British political thought from the Restoration to the Wilkites and discusses how this evolution informed the contentious actions of the Wilkites as they formed the first mass movement to promote a specific political issue.     

Detection of a changepoint,a mean-shift accompanied with a trend change,in short time-series with autocorrelation

In this study, a changepoint model, which can detect either a mean shift or a trend change when accounting for autocorrelation in short time-series, was investigated with simulations and a new method is proposed. The changepoint hypotheses were tested using a likelihood ratio test. The test statistic does not follow a known distribution and depends on the length of the time-series and the autocorrelation. The results imply that it is not possible to detect autocorrelation and that the estimate of the autocorrelation parameter is biased. It is therefore recommended to use critical values from the empirical distribution for a fixed autocorrelation.     

Are national levels of employee harassment cultural covariations of climato-economic conditions?

Conflict in a workgroup turns into harassment if a group member is persistently confronted with negative acts with few possibilities to retaliate. Cross-national differences in such intragroup harassment are considerable but wait to be understood. In this study, survey data from 44,836 employees in 44 countries revealed that a cultural in-group orientation was associated with lower employee harassment. In addition, and in agreement with Van de Vliert's climato-economic theory of culture, workforces reported more harassment in poorer countries with more demanding climates of colder-than-temperate winters, hotter-than-temperate summers, or both. Finally, it was found that the impact of climato-economic hardships on harassment suppressed the impact of cultural in-group orientation on harassment. Using the regression equation obtained for the sample of 44 countries, national levels of employee harassment for a broader pool of 103 countries were estimated and scrutinized for their validity for future research. Data from the World Values Surveys were used to validate the estimations. The results provide the basis for a further hypothesis, that employee harassment is more prevalent in countries with either survival or self-expression cultures than in countries with cultures that are intermediate between those two extremes. The results have implications for prevention and remedial measures.     

Business and legal issues in enterprise collaborations: A German perspective

Virtual and Extended enterprises share a large amount of characteristics. Especially when it comes to the process of their foundation either one is well advised to base itself on a strong network of reliable partners. In this network each of the joining companies that form the Virtual enterprise can concentrate on their core competencies, giving the whole enterprise the chance to be extremely efficient. Bringing together the different partners and managing them is seen as being one of the biggest challenges of the Virtual enterprise. Therefore some partners will have to focus on those managing tasks. It might as well be their responsibility to ensure that no legal conflicts in regard to the foundation, dissolving, production and related topics emerge. This being especially difficult because the efficiency of a Virtual enterprise is strongly dependent on the looseness of its structure. What conflicts can appear in the described environment and how they might be solved is the focus of this article. It will be pointed out that the emergence of Virtual and Extended enterprises should be supported by general terms and conditions. This terms and conditions should be adjustable, offer the chance to establish a legal framework fitting just perfectly to the intended purpose to continuously create, adjust or dissolve Virtual enterprise. As a matter of fact a certain degree of commitment can positively expand the co-operation in a Virtual enterprise which is mainly based on trust.     

The Danish psychosocial work environment and symptoms of stress: The main,mediating and moderating role of sense of coherence

The aim of this cross-sectional study was to explore the main, mediating and moderating role of sense of coherence (SOC) on stress symptoms and on the association between perceived psychosocial work environment and stress symptoms. The sample includes 2053 Danish employees from 52 workplaces. Hierarchical regression models were applied for each measure of stress. The results strongly supported the presence of a main effect for SOC. People with high levels of SOC experienced fewer stress symptoms. A mediating effect of SOC was also supported. Thus, SOC in part explained the association between work environment and stress symptoms. In addition, some support for a moderating effect of SOC was found, suggesting that people with higher SOC coped more efficiently with work environmental strain that people with lower SOC. Taken together the regression models explained 11–32% of the variance in stress symptoms. The results suggest that measures of individual factors such as SOC should be included in analyses of the effects of work environmental factors on stress and well-being.     

Aus dem Büro in den Wald

CHANGE OR DIE. The competitiveness of business companies continuously demands innovative ideas and the willingness to implement these from executive managers. Thereby their own personal needs are often neglected. The consequences range from stress and overload up to burnout symptoms. To support an appropriate handling of the imposed work load by managers, a scientifically grounded stress-tolerance-training will be designed and evaluated. For the first time, certain outdoor exercises will be used specifically among conventional elements as active experiences of challenges outside the office can deeply strengthen the constructive handling of stressful situations.     

Permutation tests — A revival?!

It is shown that permutation tests have optimum properties for interesting classes of continuous distributions as well as for discrete ones. General conditions sufficient for uniformly maximal power on subclasses are given. Moreover, a variety of examples is presented.
