The relative value of a management information system,a simulation study

A relative value of a management information system (MIS) is defined in this paper by a ratio $\text{u}{}_1\text{u}{}_0$, where u₀ is a value of a utility function of an enterprise whose management information system is perfect, and u₁ is its value when it is not perfect and may produce inaccurate or out-of-date data among correct information. Our simulation model contains beuristics which describe the operational and strategic information system of an enterprise. The environment of the enterprise may be stable or dynamic. A mathematical formula, based on simulations, is developed. This formula describes how the relative value of an MIS depends on such factors as the accuracy of an operational information system, delays in information flow, the quality of a strategic information system, a reinvestment ratio used in the enterprise, and a number of investment periods. This formula has been found suitable in an enterprise with a strategically stable environment, but not with a turbulent environment.     

Beyond the certainty of security: On dominant and latent conceptions of “security” in modern societies

While other political programs have a relatively short history, the programatic logic of security is rather long-standing. This article argues that security as a product is a conception of modernity which came to its limits. The question arises, which kind of conception could be beyond those limits.     

The Effects of Australian Tall Poppy Attitudes on American Value Based Leadership Theory

A survey study of twenty-two Australian CEOs and their subordinates assessed relationships between Australian leader motives, Australian value based leader behaviour, subordinate tall poppy attitudes and subordinate commitment, effectiveness, motivation and satisfaction (CEMS). On the whole, the results showed general support for value based leadership processes. Subsequent regression analyses of the second main component of Value Based Leadership Theory, value based leader behaviour, revealed that the collectivistic, inspirational, integrity and visionary behaviour sub-scales of the construct were positively related with subordinate CEMS. Although the hypothesis that subordinate tall poppy attitudes would moderate value based leadership processes was not clearly supported, subsequent regression analyses found that subordinate tall poppy attitudes were negatively related with perceptions of value based leader behaviour and CEMS. These findings suggest complex relationships between the three constructs, and the proposed model for the Australian context is accordingly amended. Overall, the research supports the need to consider cultural-specific attitudes in management development.     

School Difficulties and Immigrant Background: conclusions about intercultural education

This article, based on my doctoral thesis, presents a study with respect to teachers' thinking regarding school difficulties and their attitudes toward students' immigrant backgrounds. The intention of my doctoral thesis was to study the factors surrounding immigrant students' schooling. In the prevailing thinking in Sweden, students with immigrant backgrounds are often associated with problems and difficulties, not only in administrative circles but also in practical pedagogical discussions taking place in the schools. These problems are the starting point for an analysis of the reasoning and present thinking regarding immigrant students and their school situations.     

House Demolition and Mental Health: Victims and Witnesses

This research examines the immediate effects of losing one's home and witnessing the demolition of others' houses on the mental health of Palestinian adults and children. The loss group consisted of 47 adults whose homes were demolished, the witness group of 24 adults who witnessed the house demolition, and the control group of 33 adults. The groups were compared for their anxiety, depression, and paranoiac symptoms. In addition, 38 children in the loss group, 36 children in the witness group, and 50 children in the control group were compared for their psychological symptoms. The results showed that adults who were exposed to house demolition showed a higher level of anxiety, depression, and paranoiac symptoms than the witness and control groups. The children in the loss group showed a higher level of psychological symptoms than the children in the witness and control groups. The witness group differed from the control group in having more depression among women and more psychological symptoms among children. Women suffered more from anxiety, depression, and paranoiac symptoms than men in the loss and witness groups but not in the control group.     

Gender Variations of Physiological and Psychological Strain Amongst Police Officers

This paper analyses the gender effect on reported—perceived levels of stress through examination of physical and psychological indicators. It is interesting to work with police data due to high stress levels and the male dominated work environment. This paper explores both gender differences in (perceived) stress levels as well as the underlying gender-specific sensitivity to environmental factors, such as unit cooperation, trust in the work partner, higher levels of work-life-balance and home stability, and interactional fairness. Using multivariate regression analysis we find that female officers are significantly more likely to report physical strains than males, while no gender differences are observable in regards to psychological strains. Moreover, higher levels of trust and interactional fairness at work are not able to absorb physical strain among females, but have a strong impact on males. Alternatively for both female and male officers, work-life balance and stability at home appear to reduce physical strain.     

Changes in professional vision in the context of practice

In initial teacher education, it is a challenge to foster the development of teaching skills proximal to classroom action. In this study, the impact of a combined practical and theoretical university-based term on preservice teachers’ professional vision is investigated by a video-based approach to supervising their knowledge acquisition and assessing their learning outcomes. Participants were N = 109 preservice teachers attending a 5-month theory practice term guided through video-based courses about effective teaching and learning. We measured their changes in professional vision using the video-based tool Observer. Our results show that preservice teachers positively change their professional vision during the theory practice term, especially if they show low entry levels at the beginning. Their notes on the observed teaching lessons illustrate these changes.     

Geographic Ancestry and Cause-specific Mortality in a National Population

There are marked differentials in mortality risks across regions in Finland. No exhaustive explanation to this variation has been provided, however. The aim of this paper is to analyse how geographic ancestry, as proxied by persons’ birth region and population group, interrelates with cause-specific mortality risks. Focusing on people aged between their mid-thirties and late-forties, we use longitudinal population register data that offer opportunities to account for variables that represent both persons’ social background and their own social status at young adult age. Results of Cox proportional hazard models say that these variables have substantial effects on mortality of different causes, but only a marginal impact on the variation in death rates by birth region and population group. The geographic mortality pattern is found to be specifically prominent for causes of death that are fairly unrelated to persons’ lifestyles. Our findings suggest that genetic predisposal as expressed in terms of geographic ancestry might play a relevant role in understanding mortality variation within the population of Finland.
