Attachment Styles and Aggression in Physically Abused and Neglected Children

Attachment theory provides a valuable conceptual model for understanding the role of the parent–child relationship and its consequences for the child's emerging self-concept and view of the social world. Attachment style is an individual-difference variable that is rooted in the child's early rearing experience and provides the context for later emotional, behavioral, and cognitive transactions with the environment. The aim of this study was to compare physically abused (n = 41), and neglected children (n = 38) with nonabused/nonneglected children (n = 35) aged 6–12 years, in terms of their attachment styles and their levels of aggression. We found that the physically abused children were significantly characterized by the avoidant attachment style and manifested significantly higher levels of aggression, and the neglected children were significantly characterized with the anxious/ambivalent attachment style. The strategies that the physically abused and neglected children adapted for interactions with their parents also marked their relationships outside the family. Thus, physically abused children are at risk of antisocial behavior and sustained suspicion toward the others, and neglected children are at risk of social withdrawal, and social rejection and feelings of incompetence.     

Particle Analysis for the Detection of Gunshot Residue (GSR) in Nasal Samples Using Scanning Laser Ablation and Inductively Coupled Plasma-Mass Spectrometry (SLA-ICPMS)

Currently, aluminum stub with carbon adhesive devices are used to collect inorganic gunshot residues (GSR) from the hands of a shooter. In an ideal shooting case, the gunshot particles do not persist for more than 2 h in the hands of the shooter, provided that the hands have not been washed. However, for forensic analysis and inference, the extended persistence of GSR would be desirable. This study investigates a novel GSR sampling and detection protocol. Sampling was performed in the nostrils using swab devices impregnated in ethylenediaminetetraacetic acid (EDTA). The GSRs persisted for longer periods in nasal mucus than on the hands, and particles were detected 6 h after shooting occurred. The analytical determination was conducted by scanning laser ablation-inductively coupled plasma-mass spectrometry (SLA-ICPMS) which enable the identification of the number of particles and their elemental composition. Seventeen isotope signals corresponding to ¹³C, ²⁰⁵Tl and 15 analytes that are usually associated with the composition of GSR residues were monitored: ²⁷Al, ²⁹Si, ³¹P, ³³S, ³⁵Cl, ³⁹K, ⁴⁴Ca, ⁵⁷Fe, ⁶⁰Ni, ⁶³Cu, ⁶⁶Zn, ¹¹⁸Sn, ¹²¹Sb, ¹³⁷Ba, and ²⁰⁸Pb. The SLA technique enabled the reduction of the swab analysis time to 40 min. The effectiveness of this methodology was evaluated with two types of firearms: a pistol and a shotgun. The results indicated that the methodology proposed for the analysis of the nasal GSR was effective and that it can improve or complement the forensic analyses and inferences presented in a court.     

La Generalización del Impuesto al Valor Agregado: ¿Una opción para México?

Given poor tax collection in Mexico –which has registered an average of 10 to 11 percent of the GDP over the last 10 years, while spending has remained around 20 percent–, fiscal reform has been a recurring issue in public debates. In this context, the vat generalization appears as a major option for the country. Nonetheless, its viability has been caught in a discussion tinged with dogmatic hues. This paper presents some important elements that should be taken into account in the debate regarding a generalization of the vat. If the argument for not generalizing this tax is based on the tax’s regressive turn, it should then be stressed that current tax structure has created a situation of greater inequality in terms of the recipients of the support.     

Screening and quantification of antipsychotic drugs in human brain tissue by liquid chromatography-tandem mass spectrometry: application to postmortem diagnostics of forensic interest

A quantitative LC-MS/MS method has been developed for the simultaneous determination of 17 antipsychotic drugs in human postmortem brain tissue. Sample preparation was performed using Hybrid Solid Phase Extraction-Precipitation technology for the removal of endogenous protein and phospholipid interferences. The chromatographic separation was performed for 16 min on a C8 column, which used a gradient elution of formate ammonium and acetonitrile, and a flow rate gradient. Triple quadrupole mass spectrometry was employed to generate tandem mass spectrometric (MS/MS) data of the target analytes to select the ion m/z signals. Quantitation of the analytes was performed by operating in the dynamic multiple reaction monitoring (dMRM) mode using an electrospray ionization interface. Calibration curves prepared in the spiked brain tissue were linear in the range 20-8000 ng/g (r(2)>0.993) for all drugs (except olanzapine). Within- and between-day coefficients of variation were lower than 25% for all drugs at the LOQ. The LOQ in the matrix ranged between 2 ng/g and 80 ng/g. The method was successfully applied to the unequivocal identification and accurate quantification of antipsychotic drugs in human postmortem brain tissues: therefore, this method can be used in forensic investigations.     

Between Homeland and Exile: Iranian Jewry in Zionist/Israeli Political Thought*

This article explores the contingent nature of Zionist/Israeli understandings of Iranian Jewry, a particularly important “Oriental” (Mizrahi) group that has not yet received the attention it deserves in critical scholarship. Central to the Zionist project has been a juxtaposition of the opposition between East and West, on the one hand, and, on the other hand, between Exile and Land of Israel. These oppositions can be read as extreme expressions of the desire to assimiliate the Jews into the Western narrative of enlightenment and redemption. When applied to Iranian Jews, however, these oppositions become replete with tensions and ambiguities. First I show how, during the first three decades of the state of Israel, Israelis situated the Shah's modernization programs as part of the “West”, thereby removing Iranian Jewry from an “exilic” space. I then explore how the 1979 Iranian revolution further challenged these axiomatic oppositions. Iranian Jews living in Israel posed a serious challenge to Zionism's axiomatic assumptions. Nurturing a distinct ethnic (Mizrahi) identity within the Jewish state, they resisted the majoritarian and homogenizing tendencies of Israeli hegemony and demonstrated the fractured nature of Jewish identities.     

Determinant Factors of Satisfaction with Public Services in Spain

The concept of marketing has evolved significantly, as have its applications in various sectors, including services. Diverse opinions have been expressed for and against the use of marketing techniques in public administration. In this paper, we present a conceptual and methodological review of the main contributions made by marketing to the public sector, measuring variables and related concepts that determine public satisfaction with public services. These elements, termed key drivers of opinion, were measured by reference to the information provided by the Spanish Sociological Research Centre (CIS), and provide an alternative way to display and analyse the data of interest, through perception models and figures using multivariate factor analysis. In this study, the components or factors containing the main drivers of opinion were found to be, on the one hand, commitment to efficient service, and on the other, user convenience.     

Efficiency of 'Simple' Liability Rules When Courts Make Erroneous Estimation of the Damage

The literature on liability rules shows that the damage awards under a liability rule affect the efficiency of the rule. One crucial factor that could affect the damage awards and therefore the efficiency characteristics of liability rules is the error made by a court while estimating the harm suffered by the victims. In this paper efficiency property of what we label as 'simple' liability rules when courts make errors in estimation of the damage is studied in a unified framework. The paper provides a characterization of efficient simple liability rules and shows that the biased court errors act to change the efficiency characterization of simple liability rules. A necessary and sufficient condition for a simple liability rule to be efficient in the presence of upper-biased court errors is provided. The analysis is carried out in a quite general framework.
