Identification from Chest X‐Rays: Reliability of Bone Density Patterns of the Humerus*

Abstract: A critical review of Kahana and Hiss’ study on identification from bone trabecular pattern and a test of their method conducted on the humerus are presented. Bone trabecular pattern was studied through the generation of a numerical file representing the gray scale. Using the correlation coefficient, several pairwise comparisons between numerical files were performed. The test gave nearly 30% of incorrect exclusions (the method did not recognize couples of radiographs belonging to the same subject) and 50% of misidentifications (the method recognized couples of radiographs belonging to different subjects, as belonging to the same subject); therefore, this research shows that at the present time, it is not possible to safely quantify identification through bone density patterns, of the proximal humerus taken from thoracic X‐rays. Thus, an “easy”—but dangerous—use of trabecular density patterns on this specific type of radiogram as an identification method should be currently avoided.     

Trichophyton Mentagrophytes Perforates Hair of Adult Corpses in the Gaseous Period*

Abstract: Despite the substantial literature on mycology, there are still limited reports of the interaction between fungi and human hosts in the postmortem period. Thus, the main goal of this study was to investigate the in vitro perforation test using Trichophyton mentagrophytes on hair from adult corpses in the postmortem period (gaseous period). The protocol was carried out with positive (prepubescent children’s hair) and negative controls (healthy adult hair) as well. One strain of Trichophyton rubrum was also used as a negative perforation control. Perforations were found in all the hair samples from corpses and prepubescent children after 12–14 days exposure to T. mentagrophytes and were absent in the hair samples of healthy adults. Furthermore, hair perforation was not observed with T. rubrum. Our preliminary findings suggest the use of T. mentagrophytes as a potential marker of the death interval in forensic science.     

The twenty-first century Armed Forces of the Philippines: orphan of counter-insurgency or military geared for the long war of the century?

This article examines the factors that account for the Armed Forces of the Philippines's (AFP) never-ending involvement in many wars of the third kind. It discusses the essence of counter-insurgency warfare or low-intensity conflict in the Philippine setting. The article then notes that the disruption in the US military assistance after 1992, the AFP's inability to modernize, and its continuous campaign against communist and secessionist insurgents have adversely affected its structure and overall combat efficiency. It also analyzes the impact of the global war on terror on the Philippine military's counter-insurgency operations and the reforms undertaken by the Philippine defense establishment to address these issues. In conclusion, the article argues that reforms will not lead to a significant transformation of the AFP as it will continue to be an orphan of counter-insurgency in the near future. However, if wars of the third kind will persist, this situation will paradoxically make the AFP the only military in Southeast Asia aptly geared for the long war of this century.     

Testing the Information Structure of Eastern European Markets: The Warsaw Stock Exchange

This paper investigates the content of the information set used by the agents in the Warsaw Stock Exchange - WSE. Three “candidate variables” are examined — consumers’ prices, the zloty/US$ exchange rate and the refinancing rate of the National Bank of Poland — with respect to three WSE stocks, from different sectors of the economy. The methodology employed supposes that the innovations in the price series are orthogonal to all variables within or outside the information set. Beyond the question of how to specify the agents expectations, the WSE trading rules and the high volatility period present in all monthly price series were additional problems to render it operational. Given the solutions adopted, in only three out of the nine cases tested, it was possible to reject the null that the candidate did not belong to the information set. This is a signal that macroeconomic fundamentals are still absent from the WSE.     

Exchange rate volatility in high inflation economies: An econometric study of Poland and Brazil

This paper analyses exchange rate series for Poland and Brazil. The Polish series, related to the period soon after the first liberalizing measures, presents a high volatility which is not accounted for by some selected ‘fundamentals’. The Brazilian series, though also keeping evidence of excessive volatility, is cointegrated with fundamentals similar to those of the Polish case. This raises the issue of a learning process taking place during persistent inflations. Unsuccessful one-shot stabilization plans can reinforce this process, leaving a lasting imprint in the excessive volatility pattern. The message seems clear, though maybe not easy to implement: agents take some time to learn to live in non-stable environments; to avoid this by one-shot measures — if unsuccessful — can have a very high cost and pre-empt future corrections.     

Social inequalities and collective action in times of crisis: The case of the Lisbon Metropolitan Area

During the international financial crisis, Portugal found itself in a very difficult and vulnerable socioeconomic situation that has led to an increase in social inequalities. This article seeks to understand two things: firstly, how much the impacts of the crisis contributed to a general perception that people's social position has gone backwards, compared to their pre-crisis situations; secondly, whether it is possible to link this generalized perception that living conditions have gone downhill to an increase in and diversification of collective action practices. The authors analyse data from a 2014 survey of 1,500 residents of the Lisbon Metropolitan Area, which they use to measure how far the level of collective action practices has increased and varied in accordance with a set of social inequality indicators, such as resource and educational inequalities.     

A Serious Game: Performance Management in Italian Ministries

In 2009, extensive performance management measures were introduced in Italian ministries, following a significant legislative initiative. The objectives that were initially set, however, have not yet been reached. In the paper, the authors discuss this issue, starting with the consideration of the main limits on the introduction of performance measurement systems in public organizations. The discussion leads to the conclusion that the shortcomings of performance management depend not only on the persistence of an administrative paradigm, but also on the underestimated impact of control over organizational behavior; where the latter is linked not to mechanical logic processes, but to more sophisticated forms of reactivity or even counter-intuitive sense-making processes.
