Relationships between personal control,moral reasoning,and socioeconomic status of Nigerian hausa adolescents

The Internal-External Locus of Control (I-E) Scale devised by Rotter, the revised Kohlberg's Scale of Moral Judgment, and a socioeconomic background questionnaire were administered to 97 Nigerian Hausa secondary school adolescents. Data were analyzed to find sex differences in locus of control and moral reasoning, and relationships between locus of control, moral judgment level, and socioeconomic status. Significant sex differences were not revealed in either locus of control or moral reasoning. No significant relationships between locus of control, moral judgment, and socioeconomic background were found.     

Development of a radial gel diffusion technique for the identification of urea in urine stains

A radial gel diffusion method utilizing urease and bromthymol blue has been developed for urine stain identification. Urea, present in urine in relatively high concentrations, can be detected from urine stain extracts. This technique provides both qualitative and quantitative results, and is sensitive enough to detect 0.078 micrograms/microliter of urea.     

Blood grouping in a sexual assault case: criteria and methodolgy for genetic marker analysis

A sexual assault case was received in the laboratory. Upon examination, a small bloodstain was located on a bed sheet that was recovered from the defendant's motel room. Typing the whole blood samples from the defendant and the victim revealed that both blood samples exhibited identical phenotypes in eleven different genetic markers. Gm(1) and Gm(2) analysis was then performed on the two whole blood samples which provided discrimination between the two parties.     

Gm(11) grouping of dried bloodstains

An absorption inhibition method for the detection of gamma marker Gm(11) in dried bloodstains is described. Particular reference is made to the association of Gm(11) with Gm(-1, -2). When a dried bloodstain fails to inhibit anti-Gm(1) and anti-Gm(2), this may represent a true Gm(-1, -2) result or there may be insufficient material to inhibit either antibody. The detection of Gm(11) in a bloodstain extract provides an objective means of confirming the apparent absence of Gm(1) and Gm(2) as representing a true Gm(-1, -2) result. This antigen compares very well with other blood group systems with regard to the amount of bloodstain required for analysis and its stability. No evidence is available for preferential loss of Gm(1) and Gm(2) relative to Gm(11) in dried bloodstains.     

Police legitimacy and support for vigilante violence in Pakistan

Bottoms and Tankebe recently analysed the multidimensional nature of police legitimacy and made an argument for its relevance to social order. Using survey data from three communities of varying socioeconomic conditions in Pakistan, this paper examines the links between the multiple dimensions of the Bottoms-Tankebe model of police legitimacy and support for vigilante violence. The findings show overall high levels of support for vigilantism. Regression analysis shows that experiences of police illegality consistently predict support for vigilantism across the three communities. Perceived quality of police decision-making predicts support for vigilantism in some conditions but not others. Contrary to expectations, quality of interpersonal treatment by police and police effectiveness do not explain support for vigilantism. We also found no evidence to show that feelings of obligation to obey the police mediate the influence of police legitimacy on vigilante support. The implications of these findings are discussed in this paper.     

Fatal Intoxications Due to Administration of Isosorbide Tablets Contaminated with Pyrimethamine

In January 2012, 664 cases of pyrimethamine toxicity and 151 deaths were reported among cardiac patients that had recently received free medicines from pharmacy of Punjab Institute of Cardiology, Lahore, Pakistan. These patients, ages ranged from 58 to 75 years, were prescribed simvastatin, clopidogrel, aspirin soluble, isosorbide mononitrate, and amlodipine. On examination of medications being given to them, it was found that a particular batch of isosorbide mononitrate tablets was contaminated with 50 mg pyrimethamine. Cardiac patients were taking isosorbide contaminated with pyrimethamine twice daily (100 mg pyrimethamine/day), whereas therapeutic dose of pyrimethamine for malaria is 25 mg/week. Postmortem urine, cardiac blood, and femoral blood specimens of three deceased males were submitted to author's laboratory for analysis. Postmortem toxicological analysis revealed that pyrimethamine concentration fell within the range of 1–10 μg/mL by liquid chromatography. Clinical, autopsy, histopathological, and toxicological findings strongly suggested toxicity due to pyrimethamine accumulation that resulted in deaths of these cardiac patients.     

Perspectives on Ethno-National Conflict Among Kurdish Families With Members in the PKK

This article reports the findings of an ethnographic study of families with members involved in the armed struggle for Kurdish nationalism led by the Kurdistan Workers' Party. Based on in-depth, semi-structured interviews and observations with a theoretical sample of six families in the area of Yüksekova, detailed discussions were held with twelve members of families with children, partners, or siblings involved in the conflict. Ethno-national exceptionalism plays a significant role in determining the motivations of political violence among groups, but with the additional background of the perceptions and realities of systematic racialization, de-territorialization, disenfranchisement, and cultural exclusion that affect certain Kurdish groups. The findings in this article offer critical sociological and anthropological accounts of the localized drivers of ethno-nationalism, and the motivations for and the experiences of conflict among families with members involved in the armed conflict and the “Kurdish question” in Turkey.     

The detection of clandestine graves in an arid environment using thermal imaging deployed from an unmanned aerial vehicle

The Middle East is one of the world regions that has frequently suffered from armed conflicts that resulted in mass burials. However, the detection of clandestine graves in such an arid environment by deploying remote sensing payload on unmanned aerial vehicles (UAVs) has received little attention. The present study used a UAV equipped with a thermal sensor aimed at narrowing down the search area of possible gravesites in the arid climate of Kuwait. The enclosed research area, which includes both control and experimental mass graves, was imaged for 18 months. The variation in topsoil temperature and soil moisture between the graves and their surroundings was evaluated. The results of the analysis demonstrated the effectiveness of thermal imaging techniques in detecting heat produced from buried sheep carcasses and detecting the change in grave soil moisture for our research environment for 7 and 10 months, respectively. The buried animals significantly influenced the topsoil temperature (p = 0.044), while the height from which the images were captured had an insignificant effect on the measured temperature within the range tested (p = 0.985). Furthermore, there was a negative correlation (−0.359) between grave temperature and the calculated soil moisture. The results from these cost- and time-effective search methods presented in this study confirm their potential for the detection of burial sites in an arid environment.     

Review of analytical methods for screening and quantification of fentanyl analogs and novel synthetic opioids in biological specimens

Fentanyl, fentanyl analogs, and other novel synthetic opioids (NSO), including nitazene analogs, prevail in forensic toxicology casework. Analytical methods for identifying these drugs in biological specimens need to be robust, sensitive, and specific. Isomers, new analogs, and slight differences in structural modifications necessitate the use of high-resolution mass spectrometry (HRMS), especially as a non-targeted screening method designed to detect newly emerging drugs. Traditional forensic toxicology workflows, such as immunoassay and gas chromatography mass spectrometry (GC–MS), are generally not sensitive enough for detection of NSOs due to observed low (sub-μg/L) concentrations. For this review, the authors tabulated, reviewed, and summarized analytical methods from 2010–2022 for screening and quantification of fentanyl analogs and other NSOs in biological specimens using a variety of different instruments and sample preparation approaches. Limits of detection or quantification for 105 methods were included and compared to published standards and guidelines for suggested scope and sensitivity in forensic toxicology casework. Methods were summarized by instrument for screening and quantitative methods for fentanyl analogs and for nitazenes and other NSO. Toxicological testing for fentanyl analogs and NSOs is increasingly and most commonly being conducted using a variety of liquid chromatography mass spectrometry (LC–MS)-based techniques. Most of the recent analytical methods reviewed exhibited limits of detection well below 1 μg/L to detect low concentrations of increasingly potent drugs. In addition, it was observed that most newly developed methods are now using smaller sample volumes which is achievable due to the sensitivity increase gained by new technology and new instrumentation.
