Comparative study of Greulich and Pyle Atlas and Maturos 4.0 program for age estimation in a Portuguese sample

Age estimation of living individuals has become one of the big issues of forensic anthropology. The increase of children and adolescents with no valid proof of their chronological age is a legal concern to many countries, especially in situations of illegal immigration, sub adult delinquency and juvenile work. For this purpose, the use of radiological methods for evaluation of skeletal maturation is particularly useful. In this study we compare the two of the most common methods applied in age estimation by hand/wrist radiographs: the Radiographic Atlas of Skeletal Development of the Hand and Wrist made by Greulich and Pyle (GP), 1959,and the Sempé method developed for computer--Maturos 4.0 (MT) program. These methods were applied to a sample of 230 radiographs of the hand and wrist from Portuguese children and adolescents of known sex age and age, aged between 12 and 20 years, who performed medical examination at the University of Coimbra Hospitals during 2005. The methods achieved different performances, depending on the age group. Between 12 and 15 years the bone age with the MT program is closer to the chronological age, whereas in older ages the GP Atlas method is more trustworthy. At the ages with legal consequences in Portugal (16 and 18 years) the GP Atlas method is most accurate, namely to decide whether an individual is younger or older than 18 years. Around 16 years old, although there are doubts in relation to the accuracy of both methods, GP Atlas seems to perform better.     

Does Gender Equality Affect Municipal Transparency: The Case of Spain

The influence of women in organizational transparency is an understudied vein of representative bureaucracy. Literature claims that the increase of women in formal political representation opened the opportunity to bring to public organizations gender diversity, experiences, and values different from those of men. It highlights the beneficial leadership styles and the legitimacy of public bureaucracies. Since gender equality in Spanish local government has increased in recent years, it was the trigger and the aim for this study: to understand the influence of women’s political representation on the level of Spanish municipalities’ transparency. The analysis draws on panel data econometric techniques. The results reinforce the discussion that the representation of women in local political life will increase information transparency and reduce information asymmetry in municipalities.     

Culture on the Rise: How and Why Cultural Membership Promotes Democratic Politics

Selectively using Tocqueville, many social scientists suggest that civic participation increases democracy. We go beyond this neo-Tocquevillian model in three ways. First, to capture broader political and economic transformations, we consider different types of participation; results change if we analyze separate participation arenas. Some are declining, but a dramatic finding is the rise of arts and culture. Second, to assess impacts of participation, we study more dimensions of democratic politics, including distinct norms of citizenship and their associated political repertoires. Third, by analyzing global International Social Survey Programme and World Values Survey data, we identify dramatic subcultural differences: the Tocquevillian model is positive, negative, or zero in different subcultures and contexts that we explicate.     

Prisoners' expectations of the national forensic DNA database: surveillance and reconfiguration of individual rights

In this paper we aim to discuss how Portuguese prisoners know and what they feel about surveillance mechanisms related to the inclusion and deletion of the DNA profiles of convicted criminals in the national forensic database. Through a set of interviews with individuals currently imprisoned we focus on the ways this group perceives forensic DNA technologies. While the institutional and political discourses maintain that the restricted use and application of DNA profiles within the national forensic database protects individuals' rights, the prisoners claim that police misuse of such technologies potentially makes it difficult to escape from surveillance and acts as a mean of reinforcing the stigma of delinquency. The prisoners also argue that additional intensive and extensive use of surveillance devices might be more protective of their own individual rights and might possibly increase potential for exoneration.     

Data for Y-chromosome haplotypes defined by 17 STRs (AmpFLSTR Yfiler) in two Tunisian Berber communities

The 17 Y-chromosomal short tandem repeats (STRs) included in the AmpFLSTR Yfiler PCR Amplification Kit (AB Applied Biosystems) (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and GATA H4) were typed in two Berber communities, a small village (Takrouna) and a town (Sejenane), from North Tunisia. As expected, diversity was higher in the town, even when compared with a pool of three small Berber communities, probably due to the combination of different founder effects and genetic drifts operating in the small villages.

Local political leaders and context awareness: identifying perceptions of autonomy and efficacy

Leadership theories fail to explain how leaders acquire and interpret context. This article claims that political leadership styles articulate a choice of action that results from the leader's discerned possibilities to act. In order to explore these interpreted contextual determinants of leadership styles and the degree to which “possibility” has an influence over them, our research used a multiple case study design, with extensive interviews. Focusing on context awareness as a way of unveiling style determinants, I claim that it will produce different effects on leadership styles as a consequence of the leader's sense of autonomy and of political efficacy.     

Women’s political representation and transparency in local governance

Despite the growing interest on the influence of gender in local government, the relationship between women’s political representation on municipalities, as council member or as female mayors, and transparency is an under-researched topic. This article analyses the political representation of women in Spanish local councils and their influence on the level of transparency. Results show that women’s political representation in municipalities has a positive influence on the level of transparency, increasing information transparency and reducing information asymmetry.     

Implementation of CRM systems in Portuguese Municipalities

Customer relationship management is a business strategy which dynamically integrates a set of services with the purpose of creating value for the organisation and for their customers. In Portugal, the 2009/2010 edition of ‘Simplex for Municipalities’, the action plan carried by the Portuguese government through the Secretary's Office of State for Administrative Modernisation, makes a commitment to promote a set of initiatives in order to help citizens using the public services. This process intends to reduce costs of context which burden the economic activities, making way for the modernisation of administration. Customer relationship management assumes a central role in this context. This paper presents the main results of a survey that was carried out with Portuguese municipalities, aiming a general characterisation of the adoption of customer relationship management systems, covering several aspects, from the motivations for CRM adoption to the obtained results. The improvement of the relationship with citizens and a higher information quality are some of the most important results obtained by municipalities.     

Cherry Picking with Synthetic Controls

We evaluate whether a lack of guidance on how to choose the matching variables used in the Synthetic Control (SC) estimator creates specification-searching opportunities. We provide theoretical results showing that specification-searching opportunities are asymptotically irrelevant if we restrict to a subset of SC specifications. However, based on Monte Carlo simulations and simulations with real datasets, we show significant room for specification searching when the number of pre-treatment periods is in line with common SC applications, and when alternative specifications commonly used in SC applications are also considered. This suggests that such lack of guidance generates a substantial level of discretion in the choice of the comparison units in SC applications, undermining one of the advantages of the method. We provide recommendations to limit the possibilities for specification searching in the SC method. Finally, we analyze the possibilities for specification searching and provide our recommendations in a series of empirical applications.
