This study examines self-harm in a community sample of adolescents. More specifically, the study identifies the prevalence and types of self-harm, elucidates the nature and underlying function of self-harm, and evaluates the relation of psychological adjustment, sociodemographic, and health-risk variables to self-harm. Self-report questionnaires assessing self-harm, adjustment, health behaviors, suicide history, and social desirability were completed by 424 school-based adolescents. Overall, 15% of the adolescents reported engaging in self-harm behavior. Analyses revealed gender differences across behaviors and motivations. Adolescents who indicated harming themselves reported significantly increased antisocial behavior, emotional distress, anger problems, health risk behaviors, and decreased self-esteem. Results provide support for the coping or affect regulation model of self-harm. Findings suggest that self-harm is associated with maladjustment, suicide, and other health behaviors indicative of risk for negative developmental trajectories.

Four preparation techniques for MALDI/TOF mass spectrometry were compared to determine the ability to gather intelligence for investigations through the chemical analysis of latent fingerprints, defined as “touch chemistry.” Compatible fingerprint development processes used for identification along with new techniques are necessary to evaluate touch chemistry. Ten volunteers deposited fingerprints from solvent residues containing drugs and explosives onto microscope slides. The developers included (A) fingerprint powder, (B) MALDI matrix, (C) fingerprint powder and lifting, and (D) cyanoacrylate fuming with fingerprint powder. Qualitative identification was based on ion images and spectra. The highest average detection rates (88%) were found using methods A and B. Methods C (52%) or D (18%) had limited success. Results demonstrate the importance of imaging coupled to extracted mass spectral data in detecting analytes in deposited fingerprints. Overall, the results suggest continued development of touch chemistry applications could prove useful for gathering intelligence and forensically relevant information.  相似文献

This study employs latent class analysis to construct bullying involvement typologies among 3114 students (48% male, 58% White) in 40 middle schools across the U.S. Four classes were constructed: victims (15%); bullies (13%); bully-victims (13%); and noninvolved (59%). Respondents who were male and participated in fewer conventional activities were more likely to be members of the victims class. Students who were African-American and reported being less successful at school had a higher likelihood of membership in the bullies class. Bully-victims shared characteristics with bullies and victims: Students with more feelings of anger toward others and a higher tendency toward sensation-seeking had a higher likelihood of membership in the bullies and bully-victims classes, whereas lower levels of social inclusion was associated with membership in the victims and bully-victims classes.  相似文献

The New Jersey Offshore Wind Economic Development Act (“Act”) sets precedent by establishing offshore wind renewable energy certificates (“ORECs”). To launch the OREC program and assist supply chain development, the Act incentivizes construction of in-state offshore wind manufacturing facilities by offering companies fund awards and new tax credits. The Act, nevertheless, may be subject to challenges because (a) only qualified wind energy facilities located in one area of the state are eligible for certain tax credits and (b) due to vague statutory language, disputes could arise regarding who, exactly, bears the financial risk for underwater and onshore transmission construction.  相似文献

This study is a partial test of Robert Agnew's (2006 Agnew , Robert. 2006 . “Pressured Into Crime: General Strain Theory.” Pp. 201209 in Criminological Theory: Past to Present. , 3rd ed. , edited by F. T. Cullen and R. Agnew . Oxford , England : Oxford University Press . [Google Scholar]) general strain theory. The sample consists of 39,879 juveniles between the ages of 10 and 17 from a metropolitan area in Texas with more than 5 million people. Logistic regression is used to determine the effect of living situation on drug offenders, drug recidivists, and juvenile court case outcome when race, abuse, sex, and mental health problems are controlled. Gender-specific analysis is used to test L. Broidy and R. Agnew's (1997 Agnew , Robert and Timothy Brezina . 1997 . “Relational Problems With Peers, Gender, and Delinquency.” Youth & Society 84111 .[Crossref], [Web of Science ®] [Google Scholar]) hypothesis that girls and boys react differently to strain. Results show partial support for the influence of a strained living situation on drug offenders, drug recidivists, and case outcome. Support is found for the hypothesis that boys' and girls' experiences with strain differ.  相似文献
