Why are occupational safety crimes increasing?

The objective of this article is to analyse the structure of, and trends in, reported occupational safety crimes. The central focus is directed at analysing how we might understand the substantial increase in the number of reported offences witnessed during the first decade of the 21st century. In order to analyse trends in occupational safety crimes we proceed from both official crime statistics and data that have been compiled specifically for the purposes of this study, including a nationally representative sample of offence reports relating to the occupational safety crimes reported to the police. The results show that the increase in reported offenses is primarily due to a shift in definitions and in the reactions of the authorities rather than to a powerful increase in the number of actual crimes committed. This leads to the conclusion that registered occupational safety offences should first and foremost be viewed as a measure of the work of the authorities, rather than as an indicator of real crime trends.     

Using sketch drawing to induce inconsistency in liars

Purpose. Consistency as a cue to detecting deception was tested in two experiments using sketch drawing and verbal reports in repeated interviews. Liars were expected to be less consistent than truth‐tellers. Methods. In Expt 1, 80 undergraduate students reported truthfully or deceptively about an alleged lunch date – they sketched the layout of the restaurant and then answered spatial questions about objects in the restaurant. Ratings were given for the consistency between sketches and verbal reports. In Expt 2, 34 undergraduate students reported truthfully or deceptively about completing a series of unrelated tasks – they answered spatial questions about objects in a room and then sketched the layout of the room. Proportions were calculated for the consistency between verbal reports and sketches. Results. Expt 1. Liars were rated as less consistent than truth‐tellers. Up to 80% of truth‐tellers and 70% of liars could be correctly classified. Expt 2. Liars were less consistent than truth‐tellers on consistency proportions. Up to 100% of truth‐tellers and 77% of liars could be correctly classified. Conclusions. Using sketches to induce inconsistency may be a reliable, resource efficient way to help investigators detect deception.     

The Direction of Deception: Neuro-Linguistic Programming as a Lie Detection Tool

There is a myth in popular psychology, often echoed in police literature, but as yet untested, that specific eye movements pertain to lying and truth telling. According to this line of thought, eye movements to the sender??s right indicate lying, as the sender??s eyes are drawn to the side of his/her brain where their fabrication is being created. We have put this hypothesis, derived from ??Neuro-Linguistic Programming?? to the test in two experiments. In Experiment 1, a total of 204 participants (all air passengers) were interviewed at an international airport about their forthcoming trip. All participants answered one question truthfully and one question deceptively. Some participants answered a third question truthfully, whereas others answered the same question deceptively. No conclusive evidence was found for a relationship between specific eye movements and deception. In Experiment 2, a total of 31 participants discussed their real occupation in one interview and a pretend occupation in another interview. Only three of the 31 participants revealed the eye movement pattern predicted by NLP. Reasons for the existence of the myth that liars display specific eye movements are discussed.     

Lighting and Homicides: Evaluating the Effect of an Electrification Policy in Rural Brazil on Violent Crime Reduction

Introduction

This study estimates the effects of lighting on homicides in rural areas of developing countries.

Methods

We use an IV strategy by exploring the LUZ PARA TODOS or Light for All (LPT) program that was adopted by the federal government to expand electrification to rural areas in Brazilian municipalities in the 2000s as an exogenous source of variations in access to electricity.

Results

Our results indicate a significant decrease in homicide rates in municipalities the Northeast region, which is the poorest region of the country and most affected by the policy expansion. We estimate that helping a municipality increase from zero electricity coverage to full coverage reduces homicide rates by 92 per 100,000 inhabitants. This is equivalent to moving a municipality that is at the 99th percentile to the median (zero) of the crime distribution across municipalities. In addition, we perform placebo exercises using sub-samples of predominantly urban municipalities. The results increase our confidence in the IV strategy since our primary results were from areas with a larger percentage of rural population, as should be expected by the policy.

Conclusions

This study contributes to the extant literature by investigating the effects of lighting on homicides in a different context, rural areas of a developing country (Brazil).

     

Characterization and validation studies of powerPlex 2.1, a nine-locus short tandem repeat (STR) multiplex system and penta D monoplex

In order to increase the power of discrimination for human identification purposes, a nine-locus short tandem repeat (STR) multiplex, the GenePrint PowerPlex 2.1 system (PowerPlex 2.1) developed by Promega Corporation and a separate pentanucleotide-repeat locus, Penta D, were tested. This megaplex system includes the highly polymorphic loci FGA, TPOX, D8S1179, vWA, Penta E, D18S51, D21S11, TH01, and D3S1358 and may be used in combination with the eight-locus STR multiplex, the GenePrint PowerPlex 1.1 system (PowerPlex 1.1) that has been previously developed. Three of the loci, TPOX, TH01 and vWA, have been included in both systems for quality control purposes. As with PowerPlex 1.1, PowerPlex 2.1 is also based on a two-color detection of fluorescent-labeled DNA products amplified by polymerase chain reaction (PCR) and provides a valuable tool for accurate and rapid allele determination. The primer sequences used in the PowerPlex 2.1/Penta D system are also presented in this report. To meet the "Quality Assurance Standards for Forensic DNA Testing Laboratories" (FBI), we tested the efficiency and reproducibility of the PowerPlex 2.1/PentaD system by several validation studies that were conducted as a joint project among seven laboratories. Validation tests included concordance studies, sensitivity, and species specificity determination, as well as performance in forensic and environmentally impacted samples. The results produced from these tests demonstrated the consistency and reliability of the PowerPlex 2.1/Penta D system.     

Agroecology as a territory in dispute: between institutionality and social movements

Agroecology is in fashion, and now constitutes a territory in dispute between social movements and institutionality. This new conjuncture offers a constellation of opportunities that social movements can avail themselves of to promote changes in the food system. Yet there is an enormous risk that agroecology will be co-opted, institutionalized, colonized and stripped of its political content. In this paper, we analyze this quandary in terms of political ecology: will agroecology end up as merely offering a few more tools for the toolbox of industrial agriculture, to fine tune an agribusiness system that is being restructured in the midst of a civilizational crisis or, alternatively, will it be strengthened as a politically mobilizing option for building alternatives to development? We interpret the contemporary dispute over agroecology through the lenses of contested material and immaterial territories, political ecology, and the first and second contradictions of capital.
