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.     

The Legal Image’s Forgotten Aesthetics

Aesthetics and communications theories are often applied to art, media and popular culture but not within legal empirical (audiovisual) material—despite the fact that a judicial and legal process comprises a palpable utilisation of the visual as evidence of an historical reality. Based on four distinct Swedish cases, this study analyses the court’s reasoning, interpretation and use of (audio)visual evidence. Inspired by an embodied film theory, Benjamin’s thoughts on the technical-dramaturgical components of the camera and the later Barthes’ notion of the ‘punctum’, the article discusses how (audio)visual evidence cannot be disconnected from affective and aesthetic significances that ultimately can be taken to affect the perception of truth and (the crime’s) reality. The gap between theory and practice is debated and argued as beginning to co-exist; instead of seeing (visual) theory and (judicial) practice as a dichotomy, an attempt should be made for a conversation between seemingly different but in practice related areas of knowledge. The author’s aim is to suggest that photographic and filmic evidence has a particular significance in itself, which means that the relation between (judicial) interpretation and outcome should be considered within an affective and aesthetic dimension, rather than being placed and/or theorized outside of it.     

Morphometry of latent palmprints as a function of time

In many crimes, the elapsed time between production and collecting fingermark traces is crucial. and a method able to detect the aging of latent prints would represent an improvement in forensic procedures. Considering that as the latent print gets older, substantial changes in the relative proportion of individual components secreted by skin glands could affect the morphology of ridges, morphometry could be a potential tool to assess the aging of latent fingermarks. Then, considering the very limited research in the field, the present work aims to evaluate the morphometry of latent palmprint ridges, as a function of time, in order to identify an aging pattern. The latent marks were deposited by 20 donors on glass microscope slides considering pressure and contact angle, and then were maintained under controlled environmental conditions. The morphometric study was conducted on marks developed with magnetic powder in 7 different time intervals after deposition (0, 5, 10, 15, 20, 25 or 30 days); 60 ridges were evaluated for each developed mark. The results showed that: 1) the method for the replacement and mixing of skin secretions on the palm was appropriate to ensure reproducibility of latent prints, and 2) considering the studied group, there was a time-dependent reduction in the width of ridges and on the percentage of visible ridges over 30 days. Results suggest the possibility of using the morphometric method to determine an aging profile of latent palmprints on glass surface, aiming for forensic purposes.     

Gated communities and the poor in Santiago,Chile: Functional and symbolic integration in a context of aggressive capitalist colonization of lower‐class areas

Abstract

In Santiago, Chile, the number of gated communities has increased significantly during the past few years. Although these communities are aimed at the elite, they are often located on the fringes of low‐income neighborhoods and thus change traditional segregation patterns in the city.

In many cases, gated housing communities for the upper classes are accompanied by nonresidential development, such as shopping centers and office complexes, which bring jobs into the neighborhood. We analyze case studies of lower‐class neighborhoods located near upper‐class gated communities to study the effect on the poor. We find that the spatial dispersion of real estate developments for the elite promotes some forms of social integration and provides advantages to poorer residents by bringing jobs into the neighborhood, triggering improved public services, and even sparking a renewed sense of pride among lower‐class residents.     

Running for office again: evidence from Portuguese municipal elections

Using a data set that covers all Portuguese mainland municipalities for the period 1979–2005, this study performs an empirical analysis of the economic determinants of mayors’ decisions to run for another term in office. The literature on the subject is mainly centered on the United States and, as far as we know, there are no papers addressing the economic factors influencing those choices. Probit panel estimations show that local economic conditions matter more than the national or regional economic environment. The results also confirm that political variables are important and that they influence the likelihood of seeking reelection in much the same way as they affect vote and popularity functions.     

Economic performance and turnout at national and local elections

This paper analyzes the impact of economic performance on voter turnout. We estimate an economic turnout model in which local economic variables are included in quadratic form, so that non-linear effects can be taken into account. We use panel datasets covering municipalities, from 1979 to 2005, and cross-sections of parishes (freguesias) to analyze the determinants of turnout at Portuguese municipal and legislative elections. The empirical results indicate that the performance of the national economy is important only in legislative elections and that the regional and local unemployment rates tend to have non-linear relationships to turnout. The results obtained for Flemish municipalities also provide evidence in favor of a non-linear effect of unemployment on turnout.     

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.
