Sicherheitsäquivalente zur risikoadjustierten Bewertung: Unternehmensexterne Bewertungssicht vs. unternehmensinterne Steuerungssicht Replik zu den Anmerkungen „Zum Verhältnis von Wertadditivität bei Sicherheitsäquivalenten und Risikoanalyse“ von <Emphasis Type="Italic">Reichling et al.</Emphasis> (2008)

Die Forderung nach schwacher Wertadditivit?t von Sicherheits?quivalenten ist in Abh?ngigkeit des jeweiligen Bewertungszwecks zu diskutieren. W?hrend in der unternehmensexternen Bewertungssicht, z.B. bei der Unternehmensbewertung, die Forderung nach schwacher Wertadditivit?t gut begründbar ist, stellt sie im Bereich der unternehmensinternen Steuerungssicht eine „Nice to have“-Anforderung dar. Darüber hinaus werden in der bisherigen Literatur zur Anwendbarkeit von Sicherheits?quivalenten die Kernherausforderungen der unternehmensinternen Steuerung vernachl?ssigt. Insbesondere die ad?quate Berücksichtigung stochastischer Abh?ngigkeiten im Portfolioverbund bei der Bewertung von Einzelgesch?ften mittels Sicherheits?quivalenten stellt eine Forschungslücke dar.

Emotional Empathy as Related to Mimicry Reactions at Different Levels of Information Processing

The hypotheses of this investigation were based on conceiving of facial mimicry reactions in face-to-face interactions as an early automatic component in the process of emotional empathy. Differences between individuals high and low in emotional empathy were investigated. The parameters compared were facial mimicry reactions, as represented by electromyographic (EMG) activity, when individuals were exposed to pictures of angry or happy faces. The present study distinguished between spontaneous facial reactions and facial expressions associated with more controlled or modulated emotions at different information processing levels, first at a preattentive level and then consecutively at more consciously controlled levels: 61 participants were exposed to pictures at three different exposure times (17, 56, and 2350 ms). A significant difference in facial mimicry reactions between high- and low-empathy participants emerged at short exposure times (56 ms), representing automatic, spontaneous reactions, with high-empathy participants showing a significant mimicking reaction. The low-empathy participants did not display mimicking at any exposure time. On the contrary, the low-empathy participants showed, in response to angry faces, a tendency to an elevated activation in the cheek region, which often is associated with smiling.

Risk Perceptions and Alcohol Consumption among Young People

Swedish cross-sectional survey data on young individuals was used to analyse the determinants of perceived risks of alcohol use and how these perceptions relate to drinking behaviour. Three major conclusions were drawn: (1) that people overestimate the risks of alcoholism, (2) that these risk perceptions fall substantially with age, but nevertheless imply risk overestimation, and (3) that education about alcohol, narcotics and tobacco leads individuals to perceive risks more correctly and to have lower risk beliefs. An additional finding was that individuals with higher perceived risks were less likely to consume alcohol. Equations were estimated both separately and simultaneously.     

Smart Devices in Organisationen – Von Regelungen für die Allgegenwärtigkeit von computergestützter Kommunikation

Mobile communication devices like smart phones are keystones for improving efficiency, compacting and subjectifying work. They dissolve boundaries in multiple ways and influence organization of work alike exhaustion and recreation. Legal regulations are not implemented in organizations or do not fit. Organizations find it difficult even to find rules, because there are many contradictions. Nevertheless, it is for organizations in both competition concerns as issues of workplace health promotion advisable to conduct clarification processes to availability times. Consulting can support negotiation processes.
