Dynamics of remittance practices and development: Bangladeshi overseas migrants

Remittances from migrant workers play a significant role in keeping the economy of Bangladesh vibrant, adding around six per cent to the country's GDP and helping to maintain the balance of payments. This article examines remittance flows from Hong Kong and Malaysia to Bangladesh; the dynamics of remittance practices; and the impact on the well-being of migrant families. Data were collected from 126 labour migrants (56 in Hong Kong and 70 in Malaysia) between November 2004 and October 2006. The article presents empirical data showing that while remittances are significant component of the Bangladeshi economy, a considerable amount goes to ‘unproductive’ schemes. Hence remittances at the micro level that do not significantly contribute to increasing household capacities fail to bring about the anticipated sustainable development at the macro level.

La dynamique des pratiques d'envoi de fonds et le développement : migrants bangladais à l'étranger

Les envois de fonds par les travailleurs migrants jouent un rôle considérable dans le maintien du dynamisme de l'économie du Bangladesh, car ils comptent pour environ six pour cent du PIB du pays et contribuent à maintenir la balance des paiements. Cet article examine les transferts d'argent de Hong Kong et de Malaisie vers le Bangladesh, la dynamique des pratiques d'envois de fonds et l'impact sur le bien-être des familles migrantes. Des données ont été recueillies parmi 126 ouvriers (56 à Hong Kong et 70 en Malaisie) entre novembre 2004 et octobre 2006. Cet article présente des données empiriques qui montrent que, si les envois de fonds constituent effectivement un élément considérable de l'économie bangladaise, une quantité importante va vers des programmes « non productifs ». Ainsi, les envois de fonds au niveau micro qui n'apportent pas une contribution importante à l'accroissement des capacités des ménages ne donnent pas lieu au développement durable prévu au niveau macro.

Dinâmicas de práticas de remessa e desenvolvimento: imigrantes bengaleses

As remessas feitas por trabalhadores imigrantes desempenham um papel significativo em manter a economia de Bangladesh vibrante, adicionando cerca de seis por cento do PIB do país e ajudando a manter o balanço de pagamentos. Este artigo examina os fluxos de remessa de Hong Kong e Malásia para Bangladesh, as dinâmicas das práticas de remessa e o impacto sobre o bem-estar das famílias de imigrantes. Os dados foram coletados de 126 trabalhadores imigrantes (56 em Hong Kong e 70 na Malásia) entre novembro de 2004 e outubro de 2006. O artigo apresenta dados empíricos mostrando que embora as remessas sejam um componente significativo da economia de Bangladesh, um montante considerável vai para esquemas “improdutivos”. Assim, as remessas no nível micro que não contribuem significativamente para melhorar as condições da família, não conseguem promover o desenvolvimento sustentável previsto no nível macro.

La dinámica de las remesas y el desarrollo: los migrantes de Bangladesh en el extranjero

Las remesas de los trabajadores migrantes constituyen una parte importante de la economía de Bangladesh ya que representan el seis por ciento del PIB del país y contribuyen a mantener el equilibrio de la balanza de pagos. Este ensayo analiza los flujos de remesas de Hong Kong y Malasia hacia Bangladesh, la dinámica de cómo se utilizan las remesas y su impacto en el bienestar de las familias de los migrantes. Se recopilaron estadísticas de 126 trabajadores migrantes (56 en Hong Kong y 70 en Malasia) entre noviembre de 2004 y octubre de 2006. Los datos empíricos que presenta el ensayo demuestran que, si bien las remesas son un componente significativo de la economía de Bangladesh, una parte considerable se destina a actividades “improductivas”. Por lo tanto, las remesas a nivel micro que no contribuyen de manera significativa a mejorar las condiciones de los hogares no aportan al desarrollo sustentable a nivel macro que sería deseable.     

Incivilities in nonmetropolitan communities: The effects of structural constraints, social conditions, and crime

Guided by social disorganization theory and the emerging concept of collective efficacy, this study used three sources of data, including community surveys administered to 1,125 citizens nested in thirty-one residential units, and hierarchical modeling techniques to examine the effects of structural features and collective social processes, net of property crime (i.e., burglary) and citizen-level sociodemographic characteristics, on perceived incivilities (i.e., signs of physical decay and social disorder) in nonmetropolitan communities. The results showed that respondents living in economically disadvantaged geographic areas were significantly more likely to perceive their immediate surroundings in more negative terms (i.e., higher levels of incivilities). Respondents living in residential units characterized by higher levels of collective efficacy (i.e., a composite measure consisting of both cohesion and control), however, reported significantly fewer incivility problems. When assessed separately, social cohesion partially mediated the effects of economic disadvantage. The findings indicated that social disorganization theory generalizes to less densely populated, nonmetropolitan communities.     

Race, gender, and motivation for becoming a police officer: Implications for building a representative police department

Police departments have come under increasing pressure from community groups, professional organizations, and their constituents to hire more female and minority officers. Although prior research suggested that there might be both gender and racial differences in the factors influencing the decision to enter police work, much of the work was dated and findings were mixed. The current research, conducted in spring 2002, examined motivations for entering police work among a sample of 278 academy recruits in the New York City Police Department (NYPD). Findings indicated that motivations for becoming a police officer were similar regardless of race or gender, and the most influential factors were altruistic and practical, specifically the opportunity to help others, job benefits, and security. Minor differences did emerge among male and female recruits, as well as among Whites, Hispanics, and African Americans, but the practical implications of those differences seemed limited. The article concludes with a discussion of implications for recruitment efforts as police departments seek to draw more diverse applicant pools and build more representative law enforcement agencies.     

Post-traumatic stress disorder in maltreated youth: a study of diagnostic comorbidity and child factors

The study of post-traumatic stress disorder (PTSD) in maltreated youth has received increased attention, though extensive comparisons to maltreated youth without PTSD and administrations of anxiety-based structured diagnostic interviews remain needed. We examined maltreated youth with or without PTSD using structured diagnostic interviews and standardized child self-report measures. We hypothesized that maltreated youth with PTSD, compared to their peers without PTSD, would experience significantly greater duration of abuse, diagnostic comorbidity, PTSD symptomatology, dysfunctional family environment, and avoidant coping styles. Results indicated that the group with PTSD did indeed experience significantly greater duration of abuse, diagnostic comorbidity, and PTSD symptomatology, though less so dysfunctional family environment or avoidant coping styles. The presence of a mood or anxiety disorder was highly predictive of PTSD in this sample. Results are discussed within the context of evolving etiological and maintenance models of PTSD in maltreated youth.     

<Emphasis Type="Italic">Commentary</Emphasis>: A Critical Review of Published Competency-to-Confess Measures

The development of standardized assessments for competency-to-confess evaluations has remained largely neglected for the last several decades. Groundbreaking research was conducted on Miranda waivers during the late 1970s, but researchers have failed to sustain programmatic research. This critical review focuses on four published Miranda measures (Comprehension of Miranda Rights, Comprehension of Miranda Rights-Recognition, Comprehension of Miranda Vocabulary, and Function of Rights in Interrogation). When evaluated by contemporary standards, the validation of these measures is very limited. Major improvements are needed for interrater reliability, test–retest reliability, content validity, construct validity, and criterion-related validity.     

Reliable, sensitive, rapid and quantitative enzyme-based assay for gamma-hydroxybutyric acid (GHB)

Several assays for gamma-hydroxybutyrate (4-hydroxybutyrate, GHB) have been developed based on the enzyme gamma-hydroxybutyrate dehydrogenase (GHB-DH). Enzymatic oxidation of GHB by NAD+ is coupled to diaphorase-mediated reduction of pro-dye to yield colored product. GHB-DH from Ralstonia eutropha was cloned and expressed as a stable fusion protein easily purified by affinity chromatography. Quantitative initial velocity and endpoint versions of the assay in solution are described. Michaelis-Menten parameters for oxidation of GHB and ethanol were estimated. A semi-quantitative "dipstick" version of the assay on paper also is described. Both solution endpoint and "dipstick" assays are sensitive to about 0.05 mg GHB/mL using 10 microL of sample. Ethanol at concentrations possible in urine and agents used to stabilize physiological fluids for forensics analysis do not interfere significantly. The "dipstick" assay also allows detection of GHB in alcoholic beverages after evaporation of about one-fourth drop of beverage before testing. The enzymatic assay for GHB is reliable, sensitive, inexpensive and rapid.     

Studies of the allelic diversity in micro-satellite locus D16S539, F13B, FESFPS, TH01, and TROX in European population of Russia Ural region using capillary electrophoresis

Allelic frequencies of chromosome micro-satellite locuses D16S539, F13B, FESFPS, TH01 and TPOX were determined, within the case study, in a sampling of Europeoidal individuals residing in Russia's Ural Region. The allelic variants were analyzed by capillary electrophoresis after the enzyme amplification in polymerase chain reaction with fluorescent primers. The genotypic frequencies of the studied locuses were shown not to divert with statistical reliability from Hardy-Weinberg equilibrium. The estimated aggregate discriminative potential for a panel of 5 studied locuses made 0.99995. No nonequilibrium was found by linkage between alleles of all lucuses examined within the present case study or between their alleles and the alleles of previously investigated locuses D7S820 and D13S317. The implemented testing of the population homogeneity of allelic frequencies of investigated locuses for 3 samplings of Europeoids showed a deviation for locus FESFPS versus the Ural and Polish samplings and for locus F13B in the Ural and North America samplings. The distribution of allelic frequencies of other locuses was homogenous in the compared samplings.     

Systematic differences in electropherogram peak heights reported by different versions of the GeneScan software

DNA profiling using STRs on the 310 and 3100 Genetic Analyzers routinely generates electropherograms that are analyzed with the GeneScan software available from the instrument's manufacturer, Applied Biosystems. Users have been able to choose from three different smoothing options that have been known to result in significant differences in the peak heights that are reported. Improvements in the underlying algorithm of the most recent version of the software also result in significant and somewhat predictable differences in peak height values. Laboratories that have performed validation studies using older versions of GeneScan should either reanalyze the data generated in those validation studies with the newest version of the software or otherwise take into consideration the systematically higher peak height values obtained as they begin following the recommendation of the manufacturer and use the new algorithm.     

Interpretation of a 3,4-methylenedioxymethamphetamine (MDMA) blood level: discussion by means of a distribution study in two fatalities

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy" is a currently used or abused designer drug and fatalities are frequently encountered in forensic practice. However, the question remains open whether an MDMA blood level can be toxic or even potentially lethal. In order to provide insight in the interpretation of a detected MDMA concentration, the distribution of MDMA and its metabolite 3,4-methylenedioxyamphetamine (MDA) in various body fluids and tissues was studied and discussed in two different fatalities. Apart from peripheral blood samples (such as femoral and subclavian blood), various blood samples obtained centrally in the human body and several body fluids (such as vitreous humour) were examined. In addition, various tissues such as cardiac muscle, lungs, liver, kidneys, and brain lobes were analysed. In contrast to the peripheral blood levels, high MDMA and MDA levels were found in cardiac blood and the majority of the organs, except for the abdominal adipose tissue. The high concentrations observed in all lung lobes, the liver and stomach contents indicate that post-mortem redistribution of MDMA and MDA into cardiac blood can occur and, as a result, blood sampled centrally in the body should be avoided. Therefore, our data confirm that peripheral blood sampling remains "the golden standard". In addition, a distinct difference in peripheral blood MDMA concentrations in our two overdose cases was established (namely 0.271 and 13.508 microg/ml, respectively). Furthermore, our results suggest that, if a peripheral blood sample is not available and when putrefaction is not too pronounced, vitreous humour and iliopsoas muscle can be valuable specimens for toxicological analysis. Finally, referring to the various mechanisms of death following amphetamine intake, which can result in different survival times (e.g. cardiopulmonary complications versus hyperthermia), the anatomo-pathological findings and the toxicological results should be considered as a whole in arriving at a conclusion.
