Unternehmertum jenseits des Normalunternehmertums: Für eine praxistheoretisch inspirierte Erforschung unternehmerischer Aktivit?ten

Using the example of the present casualization of labor the following article demonstrates the ??surplus value?? of a perspective on corporate activities that is enriched by insights gained from the field of the sociology of labor. Beginning with a reconstruction of the state of the art on casualization processes of dependent labor it is shown that there has indeed been an intense discussion about the erosion of the so-called standard employment relationship (Normalarbeitsverh?ltnis) and the advancing casualization of dependent labor. The question regarding the casualization of the corporate activities, however, has hardly been recognized. The article will demonstrate that there actually is an ongoing casualization of corporate activities. Moreover, the vital factors for casualization processes in corporate activities will be elaborated. Subsequent to these points, the text raises the question of the implications of a ??twofold?? casualization of labor and its social mediations. In a final step, the article focuses on the systematic-methodological potential of founding research in a theory of practice.     

Interviewing to Elicit Cues to Deception: Improving Strategic Use of Evidence with General-To-Specific Framing of Evidence

Previous research has demonstrated that the strategic use of evidence (SUE) approach of interviewing criminal suspects is effective at eliciting cues to deception. This study aims at expanding on the SUE approach by testing the technique of general-to-specific evidence framing. We conducted an experiment using a mock terrorism paradigm. Guilty participants took part in a simulated act of terrorism, while innocent participants performed a similar act involving no transgression. All participants (N?=?102) were then interviewed using one of four evidence disclosure styles (early disclosure, late disclosure, 2-step disclosure, or 4-step disclosure). We expected that disclosing evidence to the suspect gradually, with increasing specificity, would induce guilty suspects to alter their statements to a greater extent than innocent suspects. General-to-specific evidence framing effectively discriminated between guilty and innocent suspects, but results only partially supported the hypotheses.     

Ecological Belief in a Just World

To date, there is considerable evidence that the perception of injustice influences environmental behavior in a positive way. Nevertheless, some people do not take action, even if the injustice seems obvious. Concerning this matter, approaches like the belief in a just world theory or system justification theory provide an explanation. However, so far, there is no scientific research on whether the perception of ecological justice, which is taken for granted, concerning an ecological belief in a just world (EBJW) may lead to differences in people’s environmental behavior. This paper investigates a newly conceived construct of the EBJW, regarding its occurrence as well as its disposition in the context of other constructs. Therefore, a new scale has been developed for the purpose of this study by means of a questionnaire with German citizens (n = 312) examining motives for energy-relevant behavior. The scale analyses confirm the validity of the new scale. Even though the EBJW did not score high in the total sample, possibly due to significant differences between the participants (particularly socio-demographic variables and different group memberships) it can be stated that there is definitely a relationship between the EBJW and justification arguments and, ultimately, a lack of responsibility for energy saving. Regression analyses reveal that the EBJW, together with cognitive and affective appraisals of justice, can explain energy-relevant commitment, such as engagement in behavior that has negative impact on the climate. Based on these findings, it is suggested that the EBJW is measurable and that it seems to warrant further research.     

THE COGNITIVE INTERVIEW AND ITS EFFECT ON WITNESSES’ CONFIDENCE

Today there is ample evidence that the Cognitive Interview (CI) enhances witnesses’ memory. However, less is known about how the CI affects eyewitnesses’ confidence. To address this shortcoming we conducted a study analyzing how realism in confidence was affected by the CI. All participants (n=79) were first shown a filmed kidnapping. After 2 weeks we interviewed one-third of the participants according to the guidelines of the CI, one-third according to a Standard Interview (SI), and one-third were not interviewed at all (Control condition). Participants in all three conditions were then asked to answer 45 forced-choice questions, and to give a confidence judgment after each choice. For the 45 questions, no differences in accuracy were found between the three conditions. Confidence was higher in the CI and SI conditions, compared with the Control condition. CI and SI did not differ in metacognitive realism but both showed lower realism compared with the Control condition, although only CI significantly so. The results indicate that the inflation in confidence is more likely to be explained in terms of a reiteration effect, than as a consequence of the particular mnemonics characterizing the CI (e.g. “mental reinstatement of context”). In sum, CI does not seem to impair (or improve) the realism in witnesses’ confidence, and does not inflate confidence in erroneous recall, compared to a SI.     

A “weapon focus” effect in children

In this paper we examined beliefs about deception held by legal professionals. Three groups of presumed expert lie-catchers were investigated: police officers ( n =104), prosecutors ( n =158), and judges ( n =251). The experts' beliefs about deception were remarkably inconsistent with the general pattern resulting from studies mapping actual cues to deception. For example, a majority of police officers believed there is a strong relationship between (a) deceptive behaviour and gaze aversion and (b) deceptive behaviour and an increase in body movements. The scientific literature does not support this view. Furthermore, all three professional groups believed that truthful consecutive statements are more consistent than deceptive, and that it is easier to detect deception in interactive than non-interactive contexts. Research on deception shows the opposite. For five of the seven investigated items we found significant between-group differences. Both the genesis and the implications of these differences are discussed. Judging from self-ratings, the presumed experts admitted knowing close to nothing about scientific research on deception.
