Bacterial Profiling of Soil For Forensic Investigations: Consideration of Ex Situ Changes in Questioned and Known Soil Samples

Soil, being diverse and ubiquitous, can potentially link a suspect or victim to a crime scene. Recently scientists have examined the microbial makeup of soil for determining its origin, and differentiating soil samples is well-established. However, when soil is transferred to evidence its microbial makeup may change over time, leading to false exclusions. In this research, “known” soils from diverse habitats were stored under controlled conditions, while evidence soils were aged on mock evidence. Limited quantities of soil were also assayed. Bacterial profiles were produced using next-generation sequencing of the 16S rRNA gene. Overall, known soils stored open at room temperature were more similar to evidence soils over time than were known soils stored bagged and/or frozen. Evidence soils, even as little as 1 mg, associated with the correct habitat 99% of the time, accentuating the importance of considering ex situ microbial changes in soil for its successful use as forensic evidence.     

Comparison of a Multidimensional to a Unidimensional Measure of Public Service Motivation: Predicting Work Attitudes

Significant research has been conducted to understand public service motivation (PSM) in the past decades using either multidimensional or unidimensional measures. This creates uncertainty in the review process about whether findings using one approach hold when other measures are used. PSM research faces the challenge of developing a better understanding of different PSM measures and the relationships between them. This paper compares a multidimensional to a unidimensional measure of PSM, assessing the predictive validity of PSM on job satisfaction, organizational commitment, and person–organization fit. The empirical test shows that there is no significant difference in the predictive capacities of PSM on the work attitudes within the data set when using the different PSM measures. It provides some evidence that unidimensional and multidimensional measures of PSM are of comparable utility, at least within the data set used.     

Multidimensional Family Therapy in Theory and in Practice

This article reviews the family therapy case of an adolescent substance abuser through the lens of multidimensional family therapy (MDFT). Initially, the adolescent presented with suicidal ideation, depression, academic difficulties, and behavior problems. The family experienced chronically high levels of conflict, which related to the mother's depression, the father's harsh discipline, and the adolescent's sister's frequent suicidal threats and outbursts. Family therapeutic interventions helped to decrease family conflict and improve the adolescent's grades and behavior. In particular, conjoint work with the parents had a stabilizing effect on the family system. As predicted by MDFT, this stabilizing effect was shown to place the adolescent on a healthier developmental trajectory. Limitations of the case and implications for future research are also presented.     

Using multidimensional scaling for the analysis of sexual offence behaviour: A replication and some cautionary notes

Abstract

Crime scene profiling has received considerable attention, particularly in popular media. First, since low inter-rater reliability would affect the validity of profiling, we tested inter-rater agreement for 33 variables often used in manuals for the coding of crime-related behaviour. Thirty cases were chosen randomly from 146 cases of assault rape with unknown male offenders in Sweden during 1990–1994. Second, we used multidimensional scaling (MDS) with all 146 cases to replicate earlier work by Canter and Heritage (Journal of Forensic Psychiatry, 1, 185–212, 1990) regarding motivational dimensions in unknown assault rapists. On average, inter-rater reliability was good; physical behaviours were more reliably coded than were verbal behaviours. However, a two-dimensional MDS solution with the motivational dimensions suggested by Canter and Heritage was not replicated. We argue for better empirical support for the inclusion of specific variables in coding formats for crime scene information. This is particularly important for analyses like the MDS, since the number, representativity, and intercorrelations of such variables could affect results considerably.     

Political Branding: Political Candidates Positioning Based on Inter-Object Associative Affinity Index

The article presents the conception of positioning politicians based on a three-stage approach to political branding. The main assumption is that a political brand—and politician's image as its crucial component—is conceptualized as consisting of a node in memory to which a variety of associations are linked. These associations—positive, negative, or neutral—must be shared with other rival candidates as well as with an prototypical ideal candidate, understood as a model and standard of comparison while developing detailed marketing strategies. One of the most valuable methods that has been used to measure these associations is associative overlap technique developed by Szalay. This measure is based on free verbal associations and it expresses the degree of similarity among objects (words, persons, groups) based on the number of similar responses (associations) they elicit in common. The first stage of branding, candidates’ positioning in various segments of voters, focuses on such affinity between politicians and is based on multidimensional scaling techniques. At the second stage, mutual relationships between particular elements (positive and negative, common and distinctive), of which a politician's image consists, are defined. The third level of political branding links the results of positioning to voters’ decisions. This framework of branding political candidates is presented on the basis of empirical research focused on Polish presidential candidates’ perception and evaluation in the 2005 presidential election. The results of the performed research show that it is not only the strengthening of politicians’ positive features but also neutralizing the negative ones that contributes to his higher expected quality.     

To adapt or to defend? Comparing position shifts among Bundestag candidates between 2013 and 2017

In this research note, candidate survey data from the German Longitudinal Election Study (GLES) is used to analyse positional shifts of German Bundestag parties between 2013 and 2017. Two developments make Germany a particularly interesting case: (1) the liberal but also controversial policies of the Merkel cabinet during the European refugee crisis and (2) the change of leadership within the right-wing populist party Alternative für Deutschland (AfD). Applying scaling techniques to locate candidates of both elections in the same two-dimensional policy space, the analysis demonstrates that in 2017 the AfD took a distinct radical right position in the party system of Germany. Moreover, the study finds that almost all parties moved to the right on the cultural left–right dimension in 2017, whereas for the economic left–right dimension this has not been the case. Contrary to the mantra of an ideological delineation against right-wing populism, there has been a robust socio-political conservative shift in the German party system.     

A shortened child behavior checklist for delinquency studies

This study examines the reduction of the number of items in the scales of the Child Behavior Checklist, while maintaining the reliability and predictability of its original scales. For that purpose, the original scales were replicated with data from the Pittsburgh Youth Study. New, abbreviated scales were constructed using the most potent items. This process yielded trimmed scales that were highly correlated with the full scales and that still reflect the original meanings of the scales. Further, there was no loss of reliability or predictability with the trimmed as opposed to the full scales. The results were replicated in an analysis with identical variables from the Rochester Youth Development Study. This replication produced equally high reliabilities with similar levels of prediction of delinquent behavior.We would like to thank Terence P. Thornberry for helpful comments and advice on early drafts of this paper.

The Downsian roots of affective polarization

A growing literature studies the relationship between ideological and affective polarization. By taking a Downsian approach to affective polarization we contribute to this literature and demonstrating that affective polarization is driven by congruence between citizens and their party, relative to other parties, in the general liberal-conservative space and across a host of salient issue domains. We find robust support for our theory using individual-level national election survey data from the United States, United Kingdom, Germany, and Finland. Moreover, we find that ideological differences inform affective polarization independently from partisan identifications and that they drive more out-party animosity than in-party affinity. These findings have implications towards a more unified understanding of the citizen determinants of affective polarization and the role ideology plays in shaping the views held by partisans across democracies.
