Reliability reporting across studies using the Buss Durkee Hostility Inventory

Empirical research on anger and hostility has pervaded the academic literature for more than 50 years. Accurate measurement of anger/hostility and subsequent interpretation of results requires that the instruments yield strong psychometric properties. For consistent measurement, reliability estimates must be calculated with each administration, because changes in sample characteristics may alter the scale's ability to generate reliable scores. Therefore, the present study was designed to address reliability reporting practices for a widely used anger assessment, the Buss Durkee Hostility Inventory (BDHI). Of the 250 published articles reviewed, 11.2% calculated and presented reliability estimates for the data at hand, 6.8% cited estimates from a previous study, and 77.1% made no mention of score reliability. Mean alpha estimates of scores for BDHI subscales generally fell below acceptable standards. Additionally, no detectable pattern was found between reporting practices and publication year or journal prestige. Areas for future research are also discussed.     

On Necessity as a Defence to Crime: Possibilities, Problems and the Limits of Justification and Excuse

The article reviews recent developments in England in the law of necessity as a defence to crime and calls for its further extension. It argues that the defence of necessity presents the criminal law with difficult questions of competing values and the ordering of harms. English law has taken a nuanced position on the respective roles of the courts and the legislature in the ordering of harms, although the development of the law has been pragmatic rather than coherently theorised. The law has granted necessity some scope as an exculpatory principle in the law of general defences, but it has also respected the primacy of the legislature as the legitimate arbiter of many of the competitions of value that necessity throws up. The recognition of necessity has not been in the form of a single unified defence of that name. Rather it has taken the form of a number of defences, based on a principle of necessity, but with different nomenclature and different rationales. This approach to necessity is defended as right in terms of principle and policy. Any further development of necessity as a general defence should be restricted to two contexts, namely those of emergencies, and of conflicts of duty, where a danger of death or serious injury is present.

Direct amplification of STRs from blood or buccal cell samples

Forensic databasing laboratories routinely analyze blood or buccal cell samples deposited on FTA^® paper. Prior to PCR amplification of the STRs, the FTA^® samples must undergo multi-step sample purification protocols to remove the PCR inhibitors present within the sample and from the FTA^® paper. The multi-step sample purification protocols are laborious, time-consuming and increase the potential for sample cross-contamination.To eliminate the need for DNA purification, we conducted studies to optimize the PCR buffer and thermal cycling parameters to allow for direct amplification of STRs from blood or buccal samples on FTA^® paper. We evaluated the effect of various factors on the DNA profile including: FTA^® disc size, blood sample load variation, and buffer formulation. The new STR assay enables the direct amplification of DNA from single source samples on FTA^® discs without sample purification. The new STR assay improves the workflow by eliminating tedious steps and minimizing sample handling. Furthermore, the new STR assay reduces cost by eliminating the need for purification reagents and expensive robots.     

A century (plus) of parenthood: Changes in living with children, 1880–1990

This paper summarizes the broad foundations of the changing nature of parenthood by examining trends in coresidence with children under age 15. Our study uses data from the Integrated Public Use Microdata Samples (IPUMS) to provide a portrait of demographic parenthood in the US over the nineteenth and twentieth centuries. In describing changes in parenthood over the past 110 years, we distinguish between those living with own children and those living with other children. We focus in particular on changes in gender patterns of coresidential parenthood and changes in the likelihood that divorced men and women live with children. We also examine the impact of the baby boom on parenting. Our findings support a recasting of ongoing discussions of the parental roles of American men and women by shifting the historical demographic focus from biological transitions to the social aspects of parenting.     

Covid-19 and UK Universities

Universities UK (UUK) has suggested that there may be very significant losses to higher education as a consequence of Covid-19. However, losses are likely to be substantially lower than the potential losses estimated by UUK. But the magnitude of losses is very uncertain. The UUK’s proposal to restrict undergraduate enrolment per university to stop institutions poaching students is not in the interests of the most highly regarded universities, or that of students. Some rationalisation of the sector should be the price of further government support. Now is also the time to reconsider how university research is funded.     

Single-party government,Prime Minister psychology,and the diversionary use of force: theory and evidence from the British case

ABSTRACT

This paper develops expectations about the likelihood of diversionary conflict initiation by parliamentary democracies with single-party majoritarian (SPM) governments. While most of the literature on diversion and governmental arrangement claims that SPMs have little incentive and/or limited capacity to execute diversionary gambits, we contend that the structural and environmental impetuses for diversion in such states are in fact largely indeterminate. We posit that the psychological attributes of prime ministers under SPM – in particular, their level of distrust – is the most important predictor of how they view structural and environmental constraints, and thus of whether they will militarily divert from poor economic conditions. Distrustful prime ministers are predisposed to the use of force, will dwell on the costs of economic problems, and fear that co-partisan MPs (especially in the cabinet) have designs on their office. Thus, despite having a legislative majority, these leaders will choose diversionary conflict over economic policy fixes. We conduct a partial test of this hypothesis in the British case from 1945 to 2007, and our analyses provide robust support.     

Measuring the “personal vote” of members of Congress

This paper uses a pooled time series/cross sectional research design to measure the “personal vote” of three groups of members of Congress. The personal vote is defined here as that part of a candidate's vote share that is unique to him or her. It is measured using a legislator-specific intercept for each legislator in an equation predicting vote share. The other variables in the equation account for the effects of the election year environment and the tenure of the representative. Three cohorts of representatives are analyzed: 1) those whose careers ended before 1966, 2) those whose careers began after 1965, and 3) those whose careers began before 1966 but ended after. The mean legislator-specific intercept is nearly twice as large for the first group as for the second; it is 29 percentage points larger for the first than the third. A second stage regression explains these intercepts using legislator characteristics, party affiliation, region of origin, and number of terms served. The term effects increase at an increasing rate as tenure increases for all those whose careers end after 1966. Personal vote accumulates nearly twice as fast for those first elected after 1965 as for those first elected before 1966.
