Authoritarianism,socioethnic diversity and political participation across countries

It is argued in this article that threatening stimuli affect political participation levels among non‐authoritarians more than among authoritarians. Focusing on socioethnic diversity, which is known to be particularly threatening to authoritarians and to relate negatively to political participation in the general public, analyses of individual‐ and macro‐level data from 53 countries is presented which supports this thesis. Participation levels among authoritarians are largely static, regardless of a country's level of socioethnic heterogeneity, while non‐authoritarians participate considerably less in countries with relatively high levels of socioethnic heterogeneity. This suggests that authoritarians participate to a proportionately greater degree in the most diverse countries.     

Psychostimulant Use and Fatal Stroke in Young Adults

Psychostimulant use is associated with increased stroke risk. To determine the proportion of psychostimulant users among fatal strokes in young adults (15–44 years), all cases were retrieved from the National Coronial Information System (1/1/2009–31/12/2016). A total of 279 cases were identified: hemorrhagic (259), ischemic (8), thrombotic (8), and mycotic (4). Fifty (17.9%) were identified as psychostimulant users. Psychostimulants in blood were detected in 37/45 where toxicology was available, predominantly methamphetamine (32/45). Hemorrhagic strokes in the psychostimulant group were more likely to be intraparenchymal (OR 2.33). Psychostimulant users were less likely to be obese (OR 0.31), but more likely to have a history of tobacco use (OR 2.64). No psychostimulant user had a previous stroke history, was gravid/postpartum, or diagnosed with cerebral vasculitis or endocarditis. The work illustrates the substantial role of psychostimulant use in fatal strokes among young adults. In cases of hemorrhagic stroke among young adults, psychostimulant use should be considered.     

Clinical Characteristics of Fatal Methamphetamine‐related Stroke: A National Study

The study aimed to determine the clinical characteristics of fatal methamphetamine‐related stroke in Australia, 2009–2015. There were 38 cases, 60.5% male, with a mean age of 40.3 years. In no case was there evidence that this was the first time methamphetamine had been used by the decedent, and 52.6% had known histories of injecting drug use. The stroke was hemorrhagic in 37 of 38 cases. In 21.1% of cases, the stroke was purely parenchymal and, in 18.4%, involved purely the subarachnoid space. A ruptured berry aneurysm was present in 31.6% and in 68.8% of initial subarachnoid hemorrhages. There was evidence of systemic hypertension in 8 of 25 cases in which full autopsy findings were available. With increased use of methamphetamine, there is a high probability of increased hemorrhagic stroke incidence among young people. In cases of fatal hemorrhagic stroke among young cases presenting to autopsy, the possibility of methamphetamine use should be borne in mind.     

Neuroscience and Neurolaw

At the intersection of neuroscience and psychological science stands neuropsychology, providing patients, triers of fact, and other parties a quantifiable, evidence-based method for understanding cognitive, emotional, and behavioral changes that occur in the context of injury or disease. The purposes of this special issue of Psychological Injury and Law are to (1) illustrate the ways in which neuroscience, psychological practice, professional ethics, and laws are intertwined in the evaluation and treatment of persons who have been injured or are experiencing a neurological disease, (2) demonstrate the ways in which neuropsychological practice is applied to forensic questions, and (3) promote quality neuropsychological practice and services to patients, courts, and other consumers of neuropsychological services. This special issue provides a sample of the types of ways that practitioners integrate neuroscience and clinical psychology, informed by and consistent with relevant laws and professional ethics, to understand people who have cognitive, emotional, and/or behavioral problems stemming from neurological injuries or other disorders.     

Electoral Rewards for Personal Vote Cultivation under PR-STV

Generally the assumption is that legislators act to maximise their chances of re-election, with their optimal behaviour determined by the party-centred or candidate-centred nature of the electoral system in use. Existing evidence of the impact of members' actual behaviour on subsequent electoral performance is inconclusive. This research explores whether or not legislators who choose to focus on cultivating personal votes reap rewards from the electorate under the Single Transferable Vote (STV) electoral system. Exploring electoral reward under STV is particularly significant because some legislators face intra-party competition for votes while others do not – a key determining incentive for cultivating personal votes. This study uses a survey of Irish legislators in 2002 and 2007 to measure constituency orientation and effort. The data suggest an electoral reward for personal vote cultivation, although the relationship between intra-system incentive and reward is apparently not always as expected.     

Beyond committees: parliamentary oversight of coalition government in Britain

Abstract

A legislature’s ability to engage in oversight of the executive is believed to derive largely from its committee system. For example, powerful parliamentary committees are considered a necessary condition for the legislature to help police policy compromises between parties in multiparty government. But can other parliamentary instruments perform this role? This article suggests parliamentary questions as an alternative parliamentary vehicle for coalition parties to monitor their partners. Questions force ministers to reveal information concerning their legislative and extra-legislative activities, providing coalition members unique insights into their partners’ behaviour. In order to test our argument, we build and analyse a new dataset of parliamentary questions in the British House of Commons covering the 2010?2015 coalition. As expected, government MPs ask more questions as the divisiveness of a policy area increases. Legislatures conventionally considered weak due to the lack of strong committees may nevertheless play an important oversight role through other parliamentary devices, including helping to police the implementation of coalition agreements.
