More than meets the eye: the role of psychopathic traits in attention to distress

ABSTRACT

Although psychopathic traits have long been associated with predation and violence, it is unclear how individuals high in psychopathic traits choose victims. Victim selection and violence perpetration may be facilitated by attention to, or unawareness of, distressful facial expressions. Using a novel eye-tracking paradigm, the present study aimed to identify whether psychopathic traits are associated with unconscious attentional biases to expressions of distress. A sample of 138 undergraduates (23 males, 115 females, M_age?=?20.4) viewed 80 paired images portraying a neutral, and authentic expression of either fear, pain, embarrassment, startle, or sadness. Psychopathic traits did not predict initial orientation to distressing over neutral expressions. However, callous-affective traits negatively predicted attentional maintenance to expressions of embarrassment and pain, whereas criminal tendencies and erratic lifestyle positively predicted attentional maintenance to embarrassment and pain, respectively. Findings offer insight into perceptual processing of others’ distress, with implications for violence and victim selection.     

Effects of storage time on DNA profiling success from archived latent fingerprint samples using an optimised workflow

Due to recent improvements in forensic DNA testing kit sensitivity,there has been an increased demand in the criminal justice community to revisit past convictions or cold cases.Some of these cases have little biological evidence other than touch DNA in the form of archived latent fingerprint lift cards.In this study,a previously developed optimised workflow for this sample type was tested on aged fingerprints to determine if improved short tandem repeat(STR)profiles could be obtained.Two-year-old samples processed with the optimised workflow produced an average of approximately five more STR alleles per profile over the traditional method.The optimised workflow also produced detectable alleles in samples aged out to 28 years.Of the methods tested,the optimised workflow resulted in the most informative profiles from evidence samples more representative of the forensic need.This workflow is recommended for use with archived latent fingerprint samples,regardless of the archival time.     

DNA Purification Cell Lysis and Wash Step Modifications for Low-Template DNA Sample Processing,

As DNA technology becomes increasingly sensitive, forensic laboratories are receiving more low-template DNA samples. These samples, already low in DNA content, become even more challenging to process as the available DNA becomes further reduced during the extraction step. In this study, two extraction modifications were tested to determine if the cause of DNA loss could be identified and mitigated. A double lysis technique was used to test for DNA loss in the sample collection substrate, and lysate eluates were re-extracted to determine DNA loss from inefficient binding to the silica column. Both modifications showed DNA was lost at these steps. However, resulting STR profiles from these samples had fewer peaks and lower peak heights when compared to samples processed with no extraction modifications. Overall, the potential benefits of adding these extraction modifications for low-template DNA sample processing are not enough to justify the risk associated with additional manipulation.     

The Role of Think Tanks in the Swedish Political Landscape

The term ‘think tank’ represents a heterogeneous concept and is used to characterise a diverse group of organisations. This diversity also characterises the Swedish organisations and institutions that currently fall under the think tank umbrella. In the Swedish political context, most organisations known by the public and news media as think tanks are advocacy organisations with an unambiguous ideological and political profile. Further, during the last decade, we have seen a proliferation of independent, self-declared think tanks with more specific policy agendas, such as the environment and health care. However, according to the broader understanding used in global rankings, the Swedish think tank landscape includes a range of research institutions in different policy areas. Some receive funding from the Confederation of Swedish Enterprise, corporations and private donors; others are government-funded, with Stockholm's International Peace Research Institute as a prominent example. The aim of this article is to map the Swedish think tank landscape and its borders and analyse the roles of different types of think tanks in consensual or confrontational policymaking. Strategic differences among these types are related to historical background and funding. While government-funded and some policy-sector think tanks typically represent a tradition of consensual policymaking, those funded by the Corporation of Swedish Enterprise and other business interests represent a post-corporatist development advocating neoliberal ideas and assuming a confrontational role in the expansion of private ownership and market solutions.
