DNA Recovery From Tape-Lifting Kits: Methodology and Practice

In the case of suspicious deaths, the technique of 1:1 taping is often used in Belgium. It consists of affixing a large number of adhesive tapes to the body of the victim. It is conventionally aimed at obtaining microtraces (e.g., fibers, hair) and is usually not used for DNA analysis. However, in some cases, DNA analysis of certain areas of interest identified on the 1:1 taping material can offer a last resort solution. The four-step method that is described in this article involves the selection of areas of interest on the body (Step 1), the selection of the corresponding tapes (Step 2), the decontamination of the tapes (Step 3), the selection of areas of interest on the tapes, for DNA sampling (Step 4). The method is illustrated by its successful application in four murder cases. In each case, DNA profiles of good quality could be identified, including profiles of persons different from the victim.     

Volatile Organic Compound Profiling from Postmortem Microbes using Gas Chromatography–Mass Spectrometry

Volatile organic compounds (VOCs) are by-products of cadaveric decomposition and are responsible for the odor associated with decomposing remains. The direct link between VOC production and individual postmortem microbes has not been well characterized experimentally. The purpose of this study was to profile VOCs released from three postmortem bacterial isolates (Bacillus subtilis, Ignatzschineria indica, I. ureiclastica) using solid-phase microextraction arrow (SPME Arrow) and gas chromatography–mass spectrometry (GC-MS). Species were inoculated in headspace vials on Standard Nutrient Agar and monitored over 5 days at 24°C. Each species exhibited a different VOC profile that included common decomposition VOCs. VOCs exhibited upward or downward temporal trends over time. Ignatzschineria indica produced a large amount of dimethyldisulfide. Other compounds of interest included alcohols, aldehydes, aromatics, and ketones. This provides foundational data to link decomposition odor with specific postmortem microbes to improve understanding of underlying mechanisms for decomposition VOC production.     

Analyzing block randomized studies: the example of the Jersey City drug market analysis experiment

Objectives

While block randomized designs have become more common in place-based policing studies, there has been relatively little discussion of the assumptions employed and their implications for statistical analysis. Our paper seeks to illustrate these assumptions, and controversy regarding statistical approaches, in the context of one of the first block randomized studies in criminal justice—the Jersey City Drug Market Analysis Project (DMAP).

Methods

Using DMAP data, we show that there are multiple approaches that can be used in analyzing block randomized designs, and that those approaches will yield differing estimates of statistical significance. We develop outcomes using both models with and without interaction, and utilizing both Type I and Type III sums-of-squares approaches. We also examine the impacts of using randomization inference, an approach for estimating p values not based on approximations using normal distribution theory, to adjust for possible small N biases in estimating standard errors.

Results

The assumptions used for identifying the analytic approach produce a comparatively wide range of p values for the main DMAP program impacts on hot spots. Nonetheless, the overall conclusions drawn from our re-analysis remain consistent with the original analyses, albeit with more caution. Results were similar to the original analyses under different specifications supporting the identification of diffusion of benefits effects to nearby areas.

Conclusions

The major contribution of our article is to clarify statistical modeling in unbalanced block randomized studies. The introduction of blocking adds complexity to the models that are estimated, and care must be taken when including interaction effects in models, whether they are ANOVA models or regression models. Researchers need to recognize this complexity and provide transparent and alternative estimates of study outcomes.

     

The contribution of the right to information laws in Europe to local government transparency on sustainability

The aim of this paper is to examine the influence of the right to information laws on sustainability transparency in European local governments. This goal is novel, in that previous studies have examined the effects of various factors on the dissemination of government information (demographic, socioeconomic, political and financial) but not the contribution of legal factors to online transparency on environmental, social and economic sustainability. Our research question is this: Do information laws contribute to transparency on sustainability? Using the Global Reporting Initiative guidelines and a statistical regression analysis, we studied the websites of 106 local governments in ten European countries. The results obtained show that when transparency laws clearly stipulate the rules applicable and the procedures established for appeals, exceptions, refusals and requests, this can favour transparency on environmental, social and economic sustainability. Our findings advance understanding of this field and reinforce the basis for legal reforms to enhance sustainability transparency.

The Catalytic Effect of IMF Lending: Evidence from Sectoral FDI Data

Our study contributes to the search for the elusive catalytic effect of International Monetary Fund (IMF) lending on inflows of foreign direct investment (FDI). Recent scholarship has found that the catalytic effect is conditional on political regime and program stringency. We contribute to this literature by developing and testing a theory which describes how the catalytic effect also varies by economic sector. This is a departure from existing studies, which have tended to focus on aggregate FDI flows after crises. Our findings corroborate previous research, which finds that in general IMF lending has a substantial and negative effect on FDI. However, we find that the negative effect is concentrated in sectors that are highly dependent on external capital and have low sunk costs in the host country. Our findings are robust to several alternative explanations common in IMF literature, namely the importance of IMF program design and the ability of governments to make credible commitments to reform. Substantively, our findings suggest that investors are more likely to use IMF lending as an escape hatch in countries where FDI is dependent on external capital and has low sunk costs.     

Towards global relational theorizing: a dialogue between Sinophone and Anglophone scholarship on relationalism

Abstract

What is ‘relational theorizing’ in International Relations and what can it offer? This article introduces a thematic section that responds to these questions by showing two things. First, relational theorizing is not a doctrine or a method, but a set of analyses that begin with relations rather than the putative essences of constitutively autonomous actors. Second, relational theorizing has emerged from different geo-linguistic traditions, and a relational approach to International Relations (IR) can offer the language and space for increased and productive engagement beyond Anglophone scholarship. This thematic section takes a significant step in this direction by staging a dialogue between Sinophone and Anglophone scholarship on relational IR theorizing. Such an engagement shows points of comparison and contrast, convergence and divergence. In this way, the essays presented here contribute to developing a more ‘global’ IR.     

The Culture of Interest: A Proposed Addition and Revision of the Three‐Culture Model

Negotiation and conflict resolution theorists have classified world cultures according to three types for the purpose of describing and predicting some of the ways in which individuals and groups within broad, geographically based cultural groups behave in conflict and negotiation‐related situations. These three broad categories, called “cultural syndromes,” have described these cultures according to the relative value they place on these three concerns: honor, face, and dignity. Based on our examination of the literature on the cultural dimensions of negotiation and conflict management, our own practice, and an analysis of literature and practice pertaining to the place and utility of the honor, face, interest, and dignity attributes within and between cultural groups , we propose a reformulation of this typology. Our reformulation would replace the broad “dignity” category with a new category that we call “interest,” which we believe better characterizes Northern European and North American cultures. We also argue that a cultural orientation toward dignity is universal and not geographically unique and is thus shared by all three cultures. This new formulation, we believe, more accurately characterizes the global range of orientations toward negotiation and conflict resolution and would, if adopted, help scholars and practitioners better understand culturally divergent conflict orientations and behaviors as well as the ramifications of such differences for negotiation and conflict resolution practice.     

Contested geopolitical messages for tourists at the Okinawa Peace Park and memorials

Abstract

Now marketed as a tropical beach destination, Okinawa's identity is also forever linked with the horrors of war. Okinawa's tumultuous past encompasses the Ryukyu Islands, which had close economic ties to China until being annexed by mainland Japan, were invaded by the US in the Second World War, were occupied until 1972 and, more recently, have become the centre of heated debates over the continued presence of US military bases. The Battle of Okinawa was one of the bloodiest of the Second World War and the inhabitants faced not only the American invasion but also the tactics of the Japanese army, who viewed the islands as expendable in order to slow invading forces from reaching mainland Japan. In the context of the seventieth anniversary of the end of the Battle of Okinawa in 2015, and beyond, it is argued here that these conflicting geopolitical disputes present significant challenges in terms of the messages presented to educational dark tourists visiting the Okinawa Peace Park and Memorials. The Peace Park Story Tellers or kataribe who are the Second World War survivors, have the critical task of mediating the message to both domestic and international tourists, some of whom are not prepared to hear anti-Japan sentiment. Through an examination of the historical and geographic background, and an analysis of the tourist experience at the Peace Park and Memorials, this paper explores the complexity of educational dark tourism where competing messages collide.     

Youth Adversities Amplify the Association between Adult Stressors and Chronic Inflammation in a Domain Specific Manner: Nuancing the Early Life Sensitivity Model

There is strong evidence that chronic, systemic inflammation hastens onset of the diseases of old age that ultimately lead to death. Importantly, several studies suggest that childhood adversity predicts chronic inflammation. Unfortunately, this research has been plagued by retrospective reports of childhood adversity, an absence of controls for adult stressors, and a failure to investigate various competing models of the link between childhood adversity and chronic inflammation. The present study was designed to address these limitations. Using 18 years of data collected from 413 African Americans (58% female) included in the Family and Community Health Study, hierarchical regression analyses provided support for a nuanced early life sensitivity explanation for the link between early adversity and adult chronic inflammation. Controlling for health risk behaviors and adult SES, late childhood (ages 10–12) adversity amplified the association between adult adversity (age 29) and chronic inflammation. This interaction operated in a domain-specific fashion. Harsh parenting amplified the relation between intimate partner hostility and inflammation, whereas early discrimination amplified the relation between adult discrimination and inflammation. These findings suggest that individuals may be primed to respond physiologically to adverse adult circumstances that resemble those experienced earlier in life.
