Perceptions of Racism and Depressive Symptoms in African American Adolescents: The Role of Perceived Academic and Social Control

Experiences with racism are a common occurrence for African American youth and may result in negative self perceptions relevant for the experience of depressive symptoms. This study examined the longitudinal association between perceptions of racism and depressive symptoms, and whether perceived academic or social control mediated this association, in a community epidemiologically-defined sample of urban African American adolescents (N = 500; 46.4% female). Structural equation modeling revealed that experiences with racism were associated with low perceived academic control, which in turn was associated with increased depressive symptoms. Findings suggest that experiences with racism can have long lasting effects for African American youth’s depressive symptoms, and highlight the detrimental effects of experiences with racism for perceptions of control in the academic domain. Implications for intervention are discussed.

Atrocities and armed conflict: state consolidation in Israel, 1948–56

This paper contrasts four cases of atrocity in the early years of the Israeli state and contends that, due to ethnic-cleansing incentives, competitive inducements and outbidding, the stated Israeli ideology of self-restraint had little impact on policy. The article further argues that, during the early periods of democratic state consolidation, democratic states act in very similar ways to authoritarian states and that little restraint is exercised in relation to ‘enemy’ civilians located within the territorial boundaries of the new state. In this respect, arguments that democracies are superior to non-democracies with regard to respect for human rights might be called into question during the initial phases of state consolidation. The paper speci?cally questions how con?ict stalemates impact on the use of violence against noncombatants in order to tip the balance of the war and it argues against the assertion that only paramilitaries would ever use terror against unarmed civilians.     

Molecular Identification of Necrophagous Dermestes Species in South Korea Using Cytochrome c Oxidase Subunit I Nucleotide Sequences (Genus Dermestes)

Species identification of necrophagous insects found on a dead body is an essential key in applying medicolegal entomology to the estimation of postmortem interval (PMI). Due to limited morphological identification of insect evidence, several studies have identified species using molecular information such as DNA markers. While considerable cytochrome c oxidase subunit I (COI) gene sequence data of necrophagous fly species have been collected and annotated, those of necrophagous beetle species have not. Since necrophagous beetles such as Dermestes species have a larval period longer than that of flies, beetles are useful in even the late decomposition phase in estimating minimum PMI. To obtain the full-length COI gene sequences of six Dermestes species collected from South Korea, we designed primers for polymerase chain reaction amplification and sequencing. The obtained full COI nucleotide sequences were used for performing phylogenic analysis and comparison with previously reported sequences. The results demonstrated that the COI gene sequences could be used to identify forensically important Dermestes species in South Korea.     

推进新农村建设的几个关键问题

正确认识当前和今后农村形势是启动新农村建设的前提;由于中国国情和具体政治制度架构等因素,中央政府和各级地方政府在新农村建设中的作用是不同的;新农村建设要注重发挥村庄和农民的主体作用;借鉴国外经验要符合各地具体实际情况,切不可搞“一刀切”,机械照搬。     

The impurity characteristics of methamphetamine synthesized by Emde and Nagai method

Impurity profiling and classification of seized methamphetamine may play an important role in the interpretation of analytical results, the determination of the synthetic method employed, and the criminal investigations of drug traffic routes. Our study is focused on classifying seized methamphetamine samples according to the groups sorted by the types and quantities of impurities present in illicit methamphetamine samples. The samples (100 mg) were dissolved in 2 mL of potassium phosphate buffer (pH 7.0), extracted with 200 μL of ethyl acetate under basic condition, and then analyzed by gas chromatography-mass spectrometry (GC–MS) with a DB-1 capillary column (30 m × 0.25 mm i.d., 0.25 μm). Five impurities are used as criteria for the classification of seized methamphetamine samples by Emde and Nagai method. A total of fifty-two samples of seized methamphetamine were analyzed by GC–MS and classified by five organic impurities, and then sorted into four groups, which are Nagai type, Emde Type, Undetermined I type, and Undetermined II type.     

Family violence and Asian drinkers

This is a study of 70 consecutive referrals to the Department of Psychological Medicine, National University Hospital, for treatment of drinking problems. There were 31 Chinese and 39 Indian drinkers, with 63 males and 7 females. Family violence with physical abuse occurred in 21 cases (30%). One of three wives of drinkers had been physically abused, but no children were victims. Drinkers with family violence were generally younger and more severely dependent on alcohol than the non-violent drinkers. There was no relationship between family violence and the ethnicity or marital status of the drinkers.     

The Managerial Prerogative and the Employee's Obligation to Work: Comparative Perspectives on Functional Flexibility

The aim of this article is to analyse the legal regulation ofthe managerial prerogative (especially the employer’sright to direct and allocate work) and how it relates to theemployee’s obligation to work in Swedish, English andGerman law in the light of the increasing flexibilisation ofworking life. The ongoing flexibilisation of working life isoften described as an increase in adaptability and allocativeflexibility and as a shift from traditional to atypical employment.The main focus of this article is functional flexibility, whichis a matter of adaptability within permanent employment relationshipsand aims at varying the content of work, and not, as often isthe case, atypical employment and numerical flexibility. Thisarticle presents a legal dogmatic and comparative analysis ofthe employer’s right to direct and allocate work, theemployee’s obligation to work and variation in the employee’sobligation to work in Swedish, English and German law. Furthermore,the material is subjected to a functional flexibility analysis,including a general discussion on the future developments ofthe managerial prerogative.
