Whole bovine blood use in forensic research: Sample preparation and storage considerations

Mammalian whole blood sources are often used for forensic research and training when human samples cannot be sourced. While porcine, ovine and equine blood have been shown to be viable alternatives to whole human blood for forensic purposes, procurement can still pose a problem, especially for smaller and remote institutions. This work explores the use of whole bovine blood for basic bloodstain simulation. Sample preparation through the addition of ACD-A anticoagulant was optimized and storability was explored. Viscosity, surface tension, density, and packed cell volume, four fluid properties relevant to bloodstain pattern analysis, were monitored over four days and in two temperature conditions. Linear mixed models accounting for variation in the donor demonstrated that these fluid properties of the bovine blood changed predictably over time and with temperature. Whole bovine blood with 12.5% v/v ACD-A was found to be viable for use in basic bloodstain simulation at ambient and physiological temperature.     

Liberal Values in International Criminal Law: A Critique of Erdemovic

Using the Erdemovi decision as its starting point, the articleexamines the philosophical foundations of international criminallaw. It asserts that international criminal law, properly understood,represents a liberal legal system, emphasizing the rights ofthe accused over the interests of the prosecution or the goalsof international peace and security. Using the work of RonaldDworkin, it argues that international jurists should apply principlesthat invoke a respect for human rights and individual autonomyover ‘policy’. Thus, it argues that the reasoningof the Appeals Chamber of the International Criminal Tribunalfor the former Yugoslavia was flawed when it determined thatduress did not constitute a complete defence in Erdemovi.     

Texas Population Substructure and Its Impact on Estimating the Rarity of Y STR Haplotypes from DNA Evidence*

Abstract: Three sampled populations of unrelated males—African American, Caucasian, and Hispanic, all from Texas—were typed for 16 Y short tandem repeat (STR) markers using the AmpFlSTR^® Yfiler^TM kit. These samples also were typed previously for the 13 core CODIS autosomal STR loci. Most of the 16 marker haplotypes (2478 out of 2551 distinct haplotypes) were observed only once in the data sets. Haplotype diversities were 99.88%, 99.89%, and 99.87% for the African American, Caucasian, and Hispanic sample populations, respectively. F_ST values were very small when a haplotype comprised 10–16 markers. This suggests that inclusion of substructure correction is not required. However, haplotypes consisting of fewer loci may require the inclusion of F_ST corrections. The testing of independence of autosomal and Y STRs supports the proposition that the frequencies of autosomal and Y STR profiles can be combined using the product rule.     

School Suspensions and Adverse Experiences in Adulthood

The “school-to-prison pipeline” and the negative effects of suspensions, expulsions and school arrests have received increasing national attention recently. Researchers have documented some of the potential harms of these exclusionary school discipline practices for students, including academic difficulties, increased misconduct, and future justice system contact. However, these investigations have been somewhat limited in scope, as they tend to focus only on students’ academic outcomes and juvenile justice system involvement. In this paper we seek to expand upon prior studies by considering how school suspensions may affect youth in peripheral and long-lasting ways. Using data from the National Longitudinal Survey of Adolescent to Adult Health, we analyze whether being suspended from school relates to the likelihood of students experiencing a number of adverse events and outcomes when they are adults. We find that being suspended increases the likelihood that a student will experience criminal victimization, criminal involvement, and incarceration years later, as adults.     

The Law of Crime Concentration: An Application and Recommendations for Future Research

Objective

We address four outstanding empirical questions related to the “law of crime concentration” (Weisburd in Criminology 53:133–157, 2015): (1) Is the spatial concentration of crime stable over time? (2) Do the same places consistently rank among those with the highest crime counts? (3) How much crime concentration would be observed if crimes were distributed randomly over place? (4) To what degree does the spatial concentration of crime depend on places that are crime free?

Methods

The data are annual counts of violent and property crimes in St. Louis between 2000 and 2014. Temporal stability in the spatial inequality of crime is measured by computing the fraction of crimes that occur in the 5% of street segments with the highest crime frequencies each year. The spatial mobility of crime is measured by computing the number of years each street segment appears in the top 5% of street segments. Poisson simulations are used to estimate the fraction of crimes that could appear in the top 5% of street segments on the basis of chance alone. The impact of crime-free locales on the spatial concentration of crime is evaluated by comparing results from analyses that include and exclude crime-free street segments from the crime distributions.

Results

The concentration of crime is highly unequal and stable over time. The specific street segments with the highest crime frequencies, however, change over time. Nontrivial fractions of street segments may appear among the 5% with the highest crime frequencies on the basis of chance. Spatial concentration of crime is reduced when crime-free street segments are excluded from the crime distributions.

Conclusions

The law of crime concentration is not a measurement artifact. Its substantive significance, however, should be assessed in future longitudinal research that replicates the current study across diverse social settings.

     

Support for behavioral nudges versus alternative policy instruments and their perceived fairness and efficacy

An extensive debate has emerged in recent years about the relative merits of behavioral policy instruments (nudges) aimed at changing individual behavior without coercion. In this article, we examine public support for non-deliberative nudges and deliberative nudges and compare them to attitudes toward top-down regulation and free choice/libertarian options. We also examine whether support for both types of nudges is associated with perceptions of fairness and efficacy. We test these expectations with a survey experiment with 1706 UK adult respondents (representative of the population on age, gender, and location) in two policy areas (retirement savings and carbon offsets for airline passengers). We find higher levels of public support for both nudge policy options compared to top-down regulation. Support for nudges is associated with the perceived fairness of nudges more than their efficacy.     

Public or nonprofit? Career preferences and dimensions of public service motivation

While the foundational claim that PSM attracts individuals to the public sector is well established in the research literature, much uncertainty still exists about its influence on the choice between the public versus the nonprofit sector, which also frequently exhibits a strong public service mission. Little is known also about how discrete dimensions of PSM differ in their effects on such job preferences. This article addresses these shortcomings by drawing on a study that combines the measurement of separate dimensions of PSM with a policy‐capturing design that allows disentangling the effects of sector from those of other job attributes that usually correlate with it: the service orientation of the job and job security. Results show that dimensions of PSM display relevant differences in their effects on preferences across job attributes. These findings have important implications for the choice of PSM measurements in scholarly research and job selection.     

Beyond regulatory capture: Coproducing expertise for critical infrastructure protection

Complex industries such as petroleum production, civil aviation, and nuclear power produce “public risks” that are widely distributed and temporally remote, and thus tend to be ignored by the risk producers. Regulation is perhaps the most common policy tool for governing such risks, but requires expert knowledge that often resides solely within the industries. Hence, many scholars and policymakers raise concerns about “regulatory capture,” wherein regulation serves private interests rather than the public good. This paper argues that regulatory capture framing has tended to limit understanding of expertise and its role in governing public risks. Most studies of regulatory capture treat expertise as a source of knowledge and skills that are created exogenously to political processes, and which can therefore be politically neutral. By contrast, we draw on work in science and technology studies that highlight the value‐laden and relational nature of knowledge and expertise, showing how its formation is endogenous to political processes. Thus, we argue for both broadening analyses of regulatory capture to consider the historically contingent and uncertain process of creating expert knowledge, and going beyond the capture framing by considering the challenge of negotiating different epistemologies and ways of life. We illustrate this analytic strategy by examining the history of and current debate about critical infrastructure protection standards to protect the United States electric power grid from cyberattack. We conclude by considering the broader implications of these findings for governing public risks.     

Kawabata and cinema: the ambivalence of knowledge,medium, and influence

Abstract

Many researchers have considered the involvement of Kawabata Yasunari in cinema and the medium's possible influence on his literature. Such approaches, however, tend to assume a definition of the motion pictures as visuality or montage that then influences Kawabata instead of first considering Kawabata's own conception of cinema, his own film theory. By analyzing his writings on film, including his film criticism, short stories involving cinema, and his involvement in the film A Page of Madness, this paper outlines Kawabata's conception of cinema and argues that he developed a portrait of cinema that posed it as a challenge to identity, perception and knowledge itself. Often associated with the female body, the movies became to Kawabata both an object of fascination and a threat, something ultimately to be controlled through literature and the literary subject. What influenced his literature was then perhaps this perception of cinema as posing an epistemic crisis. It is his ambivalence towards this challenge that can serve as a key for elaborating on Kawabata's complicated location within prewar modernism.
