Standardization of Histological Procedures for the Detection of Toxic Substances by Immunohistochemistry in Dipteran Larvae of Forensic Importance

Immunohistochemistry (IHC) technique is an alternative toxicological analysis to detect drugs in insects of forensic importance, but it requires thorough histological procedures. In this study, we tested different fixatives—phosphate‐buffered paraformaldehyde 4% (PP), Carnoy's fluid (CF), Kahle's solution (KS), ethanol in different concentrations, and ethanol associated to PP and CF, time of fixation and histological processes for dipteran larvae's tissue, aiming to develop a sample preparation protocol for IHC application. A suitable fixation was achieved using PP for 12 and 24 h, CF for 3 h, 70% ethanol for 19 days, and 70% ethanol/CF for 2 h/3 h. Postfixation using negative pressure, two immersions in xylene for 30 min each, and one in xylene plus paraffin for 45 min increased tissue preservation. An immunohistochemical test for cocaine detection was performed using monoclonal benzoylecgonine antibody from mouse, peroxidase‐conjugated anti‐mouse IgG and visualized by 3,3′‐diaminobenzidine method showed these histological procedures didn't compromise antigenicity.     

Language Proficiency and Police Officers’ Lie Detection Performance

We examined lay persons’ and police officers’ abilities to detect lying in second-language speakers. Participants (N?=?121) viewed targets who were lying or telling the truth about an event in either their first or second languages. Overall, participants were better able to detect deception in native-language speakers than second-language speakers. In addition, they tended to believe that native-language speakers were telling the truth. However, contrary to our hypotheses, expertise did not affect lie detection performance. Implications will be discussed.     

Malaysia: Unsung Hero of the Philippine Peace Process

Abstract

The October 2012 Framework Agreement on the Bangsamoro between the Philippines and the Moro Islamic Liberation Front was a milestone in the peace negotiations. Attributing this success solely to Philippine President Benigno Aquino III's popularity fails to account for Malaysia's peace facilitation. Keeping the talks on track appeared counterintuitive as Filipino public opinion often cast Malaysia as a dishonest broker. Contrary to popular belief, Kuala Lumpur's foreign policy eschewed support for Moro secession. More importantly, the effectiveness of the Malaysian-led International Monitoring Team as a peacekeeping force fostered peace in communities. This article illustrates how mediation and local-level peace can trump national-level rhetoric.     

Capital and the Lagos Presidency: Business as Usual?

Business-state relations in Chile's new democracy had been relatively tension-free for the first two governments of the centre-left Concertación de Partidos por la Democracia. However, during the first two years of the third Concertación administration, under the presidency of Ricardo Lagos, the relationship soured dramatically. At first glance, an ideological shift in the ruling coalition's centre of gravity would seem to explain the change in business-state relations. During the first two governments more conservative factions of the centrist Christian Democratic party had controlled the Concertación. Lagos, on the other hand, represented the left pole of the coalition and his socialist credentials brought the long shadow of the past on his presidency. This, however is an insufficient cause, three additional conditions must also be taken into account. The first one considers changes in the institutional and economic context that eroded the private sector's confidence in the Concertación's commitment to maintain the free-market socioeconomic model imposed under military rule. The second and third conditions are a decline in the electoral fortunes of the Concertación in favour of conservative parties and a shift in power relations among employers' associations towards more confrontational factions.

Las funciones de los consejeros independientes de las sociedades en México: Recomendaciones para el cambio a partir de las asimetrías existentes entre la práctica y la ley

The legal notion of an independent board member was introduced to the Mexican legislation in 2005. The goal was to improve the corporate governance of the corporations listed on the stock exchange. It was thought that including the independent board members would help to better represent the interest of the minority holders, as well as to increase the level of accountability. This article challenges these ideas based on 10 interviews carried out with independent board members. It finds that what the law says is far from what actuatly occurs: they lack of an adequate level of knowledge to perform their tasks, their degree of independence is severely limited by the criteria used to appoint them and they usually ignore essential corporate information, which impede them from participating effectively in the board sessions. The article suggests the creation of an independent board member’s association, a mechanism that, along with a mandatory certification system, would improve the way in which they perform their duties.
