Effects of self-concept and perceived disapproval of delinquent behavior in school children

It is argued that a multidimensional approach to self-concept may reveal intricate relations between self-concept and delinquent behavior, and that perceived approval of delinquent behaviors from referent groups may be related to the frequency of their occurrence. To evaluate these hypotheses, 1668 students from Grade 7 to Grade 9 responded to a questionnaire that measured their general self-esteem; their self-concept with regard to physical ability, social ability, physical appearance, and academic ability; the frequency they committed 15 delinquent acts; and the perceived approval of committing these acts from their parents, teachers, and friends. Regression analyses indicated that poor academic self-concept and poor relationship with school and parents were related to a higher frequency of delinquent behavior. However, a higher frequency of delinquent behavior was related to a more positive selfconcept with regard to social ability and physical ability. Finally, higher perceived approval from parents and peers was related to more delinquent behavior. Implications of these findings for identifying the antecedents and consequences of delinquent behavior were discussed.Received his Ph.D. from University of Illinois in social, industrial, and organizational psychology.

Unanswered Questions about Japan-Russia Relations in 2017

Divergent views of Japan-Russia relations in 2017 result from leaving questions unanswered. This article seeks to answer the following queries. What is the sales pitch in Japan for Abe's wooing of Putin? Why is this rationale misleading? Why is Abe keen on pursuing Putin? What motivates Putin to encourage Abe yet hold back? When did talks hit a snag? Why was 2016 different from 2001? Is the US to blame for no breakthrough? What are the cause and effect of scapegoating for no summit success? Which Japanese criticisms—by the left or the right—of the summit make a better case? Do Abe and Putin have much freedom to maneuver? Where are Japan-Russia relations now headed? Through responses to these questions, we gain an understanding of the misleading coverage of the December 15–16 Putin visit to Japan and the difficulties ahead for Abe to achieve a breakthrough in Japan-Russia relations.     

香港中文大学的大学通识教育

通识教育虽已有百余年的历史,其理念也得到了广泛的认同,但在实践中却困难重重。香港中文大学自1963年创校以来,一直把通识教育作为本科学位课程中的有机组成部分。1986年香港中文大学对通识教育全面改革,通识课程由大学通识与书院通识组成。2002年,进一步对大学通识教育作出全面检讨,厘清中大通识教育的目标与要求,重新规划整体课程和确立有效管理与素质保证的机制。现时中文大学的大学通识教育课程,由七个学院四十多学系提供二百多门通识科目。各科教师来自不同的专业领域,开设的通识科目都以专业的深度和修养为基础;学系开办通识课程时,除考虑本科教学的目标外,更要注意学科知识与其他学科的联系,以及和现代社会生活经验的关联。同时所有科目均有严格机制定期审视,以保证通识学科的素质。     

Pathologic features of fatal shark attacks

To examine the pattern of injuries in cases of fatal shark attack in South Australian waters, the authors examined the files of their institution for all cases of shark attack in which full autopsies had been performed over the past 25 years, from 1974 to 1998. Of the seven deaths attributed to shark attack during this period, full autopsies were performed in only two cases. In the remaining five cases, bodies either had not been found or were incomplete. Case 1 was a 27-year-old male surfer who had been attacked by a shark. At autopsy, the main areas of injury involved the right thigh, which displayed characteristic teeth marks, extensive soft tissue damage, and incision of the femoral artery. There were also incised wounds of the right wrist. Bony injury was minimal, and no shark teeth were recovered. Case 2 was a 26-year-old male diver who had been attacked by a shark. At autopsy, the main areas of injury involved the left thigh and lower leg, which displayed characteristic teeth marks, extensive soft tissue damage, and incised wounds of the femoral artery and vein. There was also soft tissue trauma to the left wrist, with transection of the radial artery and vein. Bony injury was minimal, and no shark teeth were recovered. In both cases, death resulted from exsanguination following a similar pattern of soft tissue and vascular damage to a leg and arm. This type of injury is in keeping with predator attack from underneath or behind, with the most severe injuries involving one leg. Less severe injuries to the arms may have occurred during the ensuing struggle. Reconstruction of the damaged limb in case 2 by sewing together skin, soft tissue, and muscle bundles not only revealed that no soft tissue was missing but also gave a clearer picture of the pattern of teeth marks, direction of the attack, and species of predator.     

The evolution of South Africa's democracy promotion in Africa: from idealism to pragmatism

South Africa is an emerging power with fairly strong democratic institutions that were crafted during the transition from minority to majority rule twenty years ago. How has South Africa used its position and power to promote democracy in Africa? Against the backdrop of debates on democracy promotion by emerging powers, this article probes attempts by successive post-apartheid governments to promote democracy in Africa. We argue that although democracy promotion featured prominently in South Africa's policy towards Africa in the immediate post-apartheid period under Nelson Mandela, the administrations of Thabo Mbeki and Jacob Zuma faltered in advancing democratic norms. This is largely because South Africa has confronted pressures to maximize pragmatic national interests, which have compromised a democratic ethos in a continental environment where these values have yet to find steady footing.     

Rapid detection of synthetic cannabinoid receptor agonists impregnated into paper by attenuated total reflectance Fourier transform infrared spectroscopy

The last few years have witnessed the change in the modalities of smuggling of synthetic cannabinoid receptor agonists (SCRAs) by impregnating them in mail envelopes and fast parcels. Considering the aforementioned scenario, it is important to develop a portable technique to identifying SCRAs through packages. The purpose of this research was to detect SCRAs impregnated into substrates of paper using attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy. Three SCRAs that included 5F-PB-22, AB-FUBINACA and AKB-48 were purchased from Sigma Aldrich. The three SCRAs and four cutting agents were impregnated into paper of variable thickness at four concentrations (10, 15, 20, and 25 mg/mL). Spectra were collected over the wavenumber range of 650–4000 cm⁻¹ using ATR-FTIR spectroscopy and were exported to Matlab 2020b where data analysis was applied. The FTIR spectral data was able to show the three SCRAs could be detected on paper using ATR-FTIR spectroscopy and quantitatively modeled using the partial least squares regression algorithm. Principal component analysis showed separate clustering for the compounds that crystallized (5F-PB-22, AB-FUBINACA and caffeine) onto the papers surface from those impregnated into the bulk of the paper (AKB-48 and procaine) with the latter situated near blank papers in score plots. In summary, ATR-FTIR spectroscopy has proven to be a successful non-destructive technique in detecting and quantifying a selection of SCRAs impregnated into paper.     

Fatal Diabetic Ketoacidosis—A Potential Complication of MDMA (Ecstasy) Use

A 19‐year‐old woman with insulin‐dependent diabetes mellitus was found dead in bed having allegedly recently taken ecstasy and consumed alcohol. At autopsy, there were microhemorrhages in the brain with subnuclear vacuolization and Armanni–Ebstein changes in renal tubules. Biochemical analyses confirmed diabetic ketoacidosis (vitreous glucose—46.5 mmol/L; β‐OH butyrate—13.86 mmol/L.). Toxicological analyses of blood showed a low level of 3,4‐methylenedioxy‐methamphetamine (MDMA) (0.01 mg/L), with acetone but no alcohol or other common drugs. Death was attributed to diabetic ketoacidosis most likely provoked by mixed MDMA/alcohol ingestion. Although the use of illicit drugs by young individuals with diabetes mellitus is being increasingly recognized, it has been noted that there is minimal information about the relationship between drug use and acute diabetic complications. Toxicological screening of cases of lethal diabetic ketoacidosis in the young may clarify lethal mechanisms in individual cases and also help to determine the extent of this problem.
