Can analysis of a small clod of soil help to solve a murder case?

Soil forensics utilizes extensive soil information to answer legal questions and test hypotheses. The main difficulty often is the determination of different variables from a small amount of soil sample collected on the suspect. We developed a sequential mineralogical and chemical analyses to assess a limited quantity of soil vestiges (0.5 g) from a suspect's vehicle (adhered to the outside rear-view mirror and to the left front fender) involved in a murder case and compared them with the surface samples found at the victim's body disposal site at the Graciosa Road, Paraná State, Brazil. All results affirm that the suspect’s vehicle could have been in contact with the edge of the Graciosa Road, approximately the place where the victim’s body was located. As a result of the soil analysis and comparison, the results support the likely contact of the suspect’s vehicle with the crime scene.     

Evaluation of Lip Prints on Different Supports Using a Batch Image Processing Algorithm and Image Superimposition

This study aimed to develop and to assess an algorithm to facilitate lip print visualization, and to digitally analyze lip prints on different supports, by superimposition. It also aimed to classify lip prints according to sex. A batch image processing algorithm was developed, which facilitated the identification and extraction of information about lip grooves. However, it performed better for lip print images with a uniform background. Paper and glass slab allowed more correct identifications than glass and the both sides of compact disks. There was no significant difference between the type of support and the amount of matching structures located in the middle area of the lower lip. There was no evidence of association between types of lip grooves and sex. Lip groove patterns of type III and type I were the most common for both sexes. The development of systems for lip print analysis is necessary, mainly concerning digital methods.     

Al Qaeda in the Arabian Peninsula: Framing Narratives and Prescriptions

Al Qaeda in the Arabian Peninsula has positioned itself at the vanguard of a media revolution in which terrorist groups both create and frame news events to an unprecedented extent. Through the publication of its e-magazine Sada al-Malahim (The Echo of Epic Battles), the organization has sought to mobilize both Yemeni and non-Yemeni Muslim, Arabic-speaking audiences to carry out violent jihad. This article utilizes the concept of collective action frames to analyze Al Qaeda in the Arabian Peninsula's media output, identifying the organization's grievance narratives, ideological justifications for violent actions, and means to strengthen its credibility among its intended audiences.     

Neutralizing Unethical Negotiating Tactics: An Empirical Investigation of Approach Selection and Effectiveness

Negotiation is integral to business success, and information is the lifeblood of the negotiation process. When invalid information is disseminated via manipulation or deceit, one or more parties can suffer. Nonetheless, many studies have shown that the use of questionable or unethical tactics is commonplace. This article reports on a study of twelve behaviors that can neutralize a counterpart's tendencies to employ questionable or unethical tactics, improving the chances for an integrative (win–win) outcome. The results suggest that while nearly two thirds of participants employed neutralizing behaviors, they used many of these behaviors later in the negotiation process than anticipated and simultaneously alongside questionable or unethical tactics. While we found some evidence that the twelve neutralizing behaviors were viewed differently from questionable or unethical tactics, the expected attenuating effects were not found. The implications of these findings, including opportunities for future research, are discussed.     

Thermal Imaging as a Lie Detection Tool at Airports

We tested the accuracy of thermal imaging as a lie detection tool in airport screening. Fifty-one passengers in an international airport departure hall told the truth or lied about their forthcoming trip in an interview. Their skin temperature was recorded via a thermal imaging camera. Liars’ skin temperature rose significantly during the interview, whereas truth tellers’ skin temperature remained constant. On the basis of these different patterns, 64% of truth tellers and 69% of liars were classified correctly. The interviewers made veracity judgements independently from the thermal recordings. The interviewers outperformed the thermal recordings and classified 72% of truth tellers and 77% of liars correctly. Accuracy rates based on the combination of thermal imaging scores and interviewers’ judgements were the same as accuracy rates based on interviewers’ judgements alone. Implications of the findings for the suitability of thermal imaging as a lie detection tool in airports are discussed.     

Women in Television in the Multi-Channel Age

This article explores the impact of structural and technological change on women's employment in the UK television industry. It looks at the challenges faced by women in working in what has become since the mid-1980s a largely freelance industry where short-term contracts, informal recruitment procedures and long, unpredictable work schedules mean that women find it increasingly difficult to combine a career and family. Through case studies of individual careers, of a women's magazine programme for S4C Digital and a survey of women's credits on a selection of the newer channels (Sky One, UK Living and Channel 5), it argues that technological advances in digital transmission and production will not improve working conditions and opportunities for women's participation in all areas of the industry if they continue to replicate existing practice.
