The Interplay Between Greed,Efficiency, and Fairness in Public-Goods Dilemmas

The Greed–Efficiency–Fairness hypothesis (H. A. M. Wilke, In European Review of Social Psychology, Wiley, New York, Vol. 2, pp. 165–187, 1991) states that people in resource dilemmas are greedy and wish to defect, but that greed is constrained by preferences for efficient resource use and fair distributions. This paper reviews research where the GEF hypothesis was generalized to public-goods dilemmas. Results from both surveys and experiments on people's willingness to contribute to resources for social services were interpreted in light of the GEF hypothesis. Whereas earlier research on social dilemmas and fairness considerations have focused on the correlation between estimated fair and actual cooperation rates, the present results provide an extension where cooperation rates are influenced by perceived fairness of how a resource is distributed. Two experiments contribute further insights into the interplay, in terms of effects on cooperation, between greed, efficiency, and fairness. The collective consequences of individual choices were either highlighted or not (Experiment 1) and the outcome structure in prior social dilemma tasks was either collectively or individually framed (Experiment 2). These manipulations influenced (a) cooperation rates and (b) the extent to which decisions were based on greed, efficiency, or fairness.     

Strategic Use of Evidence During Police Interviews: When Training to Detect Deception Works

Research on deception detection in legal contexts has neglected the question of how the use of evidence can affect deception detection accuracy. In this study, police trainees (N=82) either were or were not trained in strategically using the evidence when interviewing lying or truth telling mock suspects (N=82). The trainees’ strategies as well as liars’ and truth tellers’ counter-strategies were analyzed. Trained interviewers applied different strategies than did untrained. As a consequence of this, liars interviewed by trained interviewers were more inconsistent with the evidence compared to liars interviewed by untrained interviewers. Trained interviewers created and utilized the statement-evidence consistency cue, and obtained a considerably higher deception detection accuracy rate (85.4%) than untrained interviewers (56.1%).     

Dumping after homicide using setting in concrete and/or sealing with bricks--six case reports

Homicide with subsequent hiding of the body using setting in concrete or sealing with bricks are rarely seen forensic cases. The article describes the circumstances and findings of six cases in which bodies were encased with concrete and/or bricks. In all cases, the offenders were male, in one case together with his wife and--except for one case--the victims were related to the offender. The causes of death were heterogeneous (suffocation, blunt force, shot) and the motive mainly domestic quarrel. Setting corpses in concrete and/or sealing with bricks does not prevent smell, slows decomposition and therefore complicates the estimation of the post mortem interval.     

New Executives from Inside or Outside? The Effect of Executive Replacement on Organizational Change

This article investigates how executive succession influences the comprehensiveness of structural changes pursued by public organizations. Executive successions are important events for organizations that provide salient opportunities for introducing organizational change, yet little research has analyzed this relationship. The author argues that the less familiarity a new executive has with the organization and the field in which it works, the more likely it is that comprehensive organizational change will take place. Empirical results from quantitative analyses of executive succession events in Danish municipalities from 1984 to 2000 confirm this. Interestingly, the degree to which new practices are legitimized moderates the findings. Inside successors are more likely to conduct comprehensive structural changes after new practices receive normative and regulatory legitimacy. The article contributes to the literature on executive succession by highlighting how it is an antecedent to different types of organizational change. Contributions to practitioner and public management research are discussed.     

Assessment of forensic findings when alternative explanations have different likelihoods—“Blame-the-brother”-syndrome

Assessment of forensic findings with likelihood ratios is for several cases straightforward, but there are a number of situations where contemplation of the alternative explanation to the evidence needs consideration, in particular when it comes to the reporting of the evidentiary strength. The likelihood ratio approach cannot be directly applied to cases where the proposition alternative to the forwarded one is a set of multiple propositions with different likelihoods and different prior probabilities. Here we present a general framework based on the Bayes' factor as the quantitative measure of evidentiary strength from which it can be deduced whether the direct application of a likelihood ratio is reasonable or not. The framework is applied on DNA evidence in forms of an extension to previously published work. With the help of a scale of conclusions we provide a solution to the problem of communicating to the court the evidentiary strength of a DNA match when a close relative to the suspect has a non-negligible prior probability of being the source of the DNA.     

Early criminal recidivism among mentally disordered offenders

Criminal recidivism was studied during 2 years in a Swedish population-based cohort (N = 318) of mentally disordered male offenders who had undergone a pretrial forensic psychiatric investigation, been convicted in subsequent trials, and been sentenced to forensic psychiatric treatment (FPT; n = 152), prison (n = 116), or noncustodial sanctions (n = 50). Recidivism was analysed in relation to index sanctions, levels of supervision, diagnoses, and criminological factors. Significantly lower recidivism in the FPT group was related to lower crime rates during periods at conditional liberty in this group alone, and recidivism was significantly more common among offenders with at least one of the two diagnoses of substance abuse disorder and personality disorder than among those with psychotic or other mental disorders alone. Age at index crime and number of previous crimes emerged as significant predictors of recidivism. The results of this study suggest that the relapse rates depend as much on level of supervision as on individual characteristics.     

A concept study on identification and attribution profiling of chemical threat agents using liquid chromatography-mass spectrometry applied to Amanita toxins in food

Accidental or deliberate poisoning of food is of great national and international concern. Detecting and identifying potentially toxic agents in food is challenging due to their large chemical diversity and the complexity range of food matrices. A methodology is presented whereby toxic agents are identified and further characterized using a two-step approach. First, generic screening is performed by LC/MS/MS to detect toxins based on a list of selected potential chemical threat agents (CTAs). After identifying the CTAs, a second LC/MS analysis is performed applying accurate mass determination and the generation of an attribution profile. To demonstrate the potential of the methodology, toxins from the mushrooms Amanita phalloides and Amanita virosa were analyzed. These mushrooms are known to produce cyclic peptide toxins, which can be grouped into amatoxins, phallotoxins and virotoxins, where α-amanitin and β-amanitin are regarded as the most potent. To represent a typical complex food sample, mushroom stews containing either A. phalloides or A. virosa were prepared. By combining the screening method with accurate mass analysis, the attribution profile for the identified toxins and related components in each stew was established and used to identify the mushroom species in question. In addition, the analytical data was consistent with the fact that the A. virosa specimens used in this study were of European origin. This adds an important piece of information that enables geographic attribution and strengthens the attribution profile.     

Lucilia silvarum Meigen, 1826 (Diptera: Calliphoridae)-A new species of interest for forensic entomology in Europe

In Europe, the blowfly genus Lucilia is represented in Forensic Entomology mainly by the species L. ampullacea, L. caesar, L. illustris and L. sericata. In the US, Lucilia silvarum is rarely recorded as a carrion breeding species but usually as a more or less exclusive parasite of frogs and toads. We present three forensic cases from different European countries reporting, for the first time, L. silvarum on human bodies that were found close to lakes, wetlands, or riversides. To use this species for post-mortem interval estimations, thermal development data is needed. The first step is accurate identification by morphological and molecular means. Therefore, we analysed a 611bp part of the mitochondrial COI region for 23 specimens of L. silvarum from 9 different geographical regions, all of which give the same haplotype. Differences within the haplotype varied by up to 0.2%. Comparison between the haplotype found and those published on GenBank showed up to 1.2% variance. Moreover, we present an updated key for the morphological identification of the third larval instars of European Lucilia spp. of forensic importance, adding not only L. silvarum, but also L. cuprina which was recorded in Europe for the first time about 20 years ago.     

Perceived Quality of Life and Health Complaints in Children Exposed to Intimate Partner Violence

Children 9 to 13 years old exposed to intimate partner violence (IPV) reported on their violence exposure, attachment to both parents, temperament (negative emotionality and emotion regulation), perceived quality of life, and health complaints. Half of the children perceived their quality of life as good and did not have recurrent health complaints. When controlling for socioeconomic status, health complaints were associated with higher IPV exposure and negative emotionality, whereas quality of life was associated with attachment security, higher capacity for emotion regulation, and lower negative emotionality. These results underscore the importance of increasing and supporting the capacity of children exposed to IPV to handle and express their emotions, as well as making school nurses and other primary care practitioners more attentive to IPV as a possible background factor in children’s health complaints.
