Teens involved with drugs and engaged in delinquent behavior lessen their life chances. This article examines the relationship between early illicit drug exposure, delinquency, and subsequent adult experience through the life history accounts of 31 men who are homeless drug addicts today. The men's retrospective reports link personal history and social circumstance to describe common pathways associated with and emerging from adolescent delinquency and drug involvement. Their accounts, framed within the social development model, indicate that the life chances of teens at risk might improve if policy-based solutions and interventions target and ameliorate contextual and interpersonal risk factors interfering with the accumulation of social capital.

Objective. To examine relationships involving three extremely high-risk behaviors (drug use, drug trafficking, and weapon carrying) among low-income, urban, African-American early adolescent boys using both quantitative and qualitative methods. Method. The quantitative phase included 192 African-American boys from 9 through 15 years of age recruited from recreation centers located in low-income communities. Youth completed a survey addressing personal risk practices; intentions to engage in risk practices; risk taking among family, friends and community; and values toward risk practices. They also completed standardized assessments of sensation seeking, perceived peer pressure, and parent-child communication. All questionnaires were self-administered through MacIntosh computers programmed to present questions aurally and visually. The qualitative phase included 12 African-American youth from low-income, urban families. The youth participated in 60- to 90-minute interviews regarding drug activities and violence. Results. Most boys (73%) were not involved in either drug activities or weapon carrying. Boys who were involved in drug activities or weapon carrying were often involved in other high-risk activities (cigarette and alcohol use, school failure and expulsion) and had low rates of adaptive communication with their parents. The boys reported high rates of drug involvement by their family, friends, and community. However, psychological and interpersonal factors were better predictors of individual risk activities than community or family variables. Personal values regarding economics predicted drug trafficking. More than 56% of the boys who reported past involvement in drug activities did not anticipate future involvement. Conclusions. Multilevel strategies are necessary to prevent involvement in drug activities and weapon carrying. Intervention programs should begin early and should promote communication between parents and children, adaptive behavior in school, and avoidance of cigarette and alcohol use. Community-level interventions are needed to alter the myth that drug involvement and weapon carrying are normative and to promote images that are less materialistic and more supportive of education and future-oriented activities.

The Eleutheronema tetradactylum is a protandrous, hermaphrodite, marine perciformes fish. The body length of this fish acts as an important diagnostic marker for male and female discrimination. The present study describes for the first time the ultrastructural characteristics on the medial surface of the sagitta otolith in different body size groups of males of E. tetradactylum (Polynemidae: Perciformes) using scanning electron microscopy. The sagitta is a spindle-shaped structure that includes a well-developed rostrum and a poorly developed antirostrum. The sulcus is ostio-pseudocaudal type, almost straight and devoid of the collum. The ostium is a well-developed, vase-shaped structure. The cauda includes the colliculum and a well-developed caudal bulb with several distinct growth stripes. The length of the caudal bulb is significantly correlated to the growth of the body size of the fish. The excisura major is indistinct and the excisura minor is absent. The cristae are distinct on both sides of the sulcus. The one-way ANOVA test revealed that the development of several sagitta features shows significant differences in various body size groups of E. tetradactylum. The growth of the sagitta length is more closely related to the fork length than the sagitta width. Therefore, the sagitta length and the caudal bulb length can be used as important predictors to evaluate the fish size. The cauda region of the sagitta in E. tetradactylum is unique as well as more decorative than those of another Polynemidae fish and other hermaphrodite, marine perciformes fishes. The sagitta characteristics of E. tetradactylum might be advantageous in the identification of the sex and the taxonomy of the hermaphrodite fish species.

Alcohol and other drug use are common in youth, but neurocognitive sequelae are unclear. This study examines the relationship between neuropsychological functioning and protracted substance use in adolescence. One hundred fifteen adolescents, ages 13 to 19 years, were recruited from inpatient substance abuse treatment programs and followed for 4 years. Adolescents were administered a comprehensive battery of neuropsychological tests and evaluated on substance use involvement during treatment, and at 6-month, 1-year, 2-year, and 4-year follow-up time points. Protracted substance abuse over the 4 years of follow-up was associated with significantly poorer subsequent functioning on tests of attention. In addition, alcohol and drug withdrawal accounted for significant variance in visuospatial functioning, above and beyond demographic, educational, and health variables in detoxified late adolescents and young adults. Results suggest that alcohol and drug withdrawal may be a more powerful marker of protracted neuropsychological impairments than other indices of youthful alcohol and drug involvement.

Background: Substance abuse is a major public health issue worldwide, particularly manifesting during the late adolescent and early adult period. Each culture has distinct beliefs and unique ways of raising children. Cultural differences in parenting beliefs and behaviors are an interesting area that enhances understanding of the nature of differences across cultures. Substance abuse risk may be related to family sociocultural factors; however, there are limited studies that address the relationships between pertinent variables. Objective: To examine and compare family sociocultural factors, sensation seeking, and risk of drug involvement among Egyptian and Saudi university students. Methods: The study employed a comparative correlational descriptive design using two-stage cluster sampling techniques. Data were collected using self-administered questionnaires distributed to students enrolled in Imam Abdulrahman Bin Faisal University (IAU) in Saudi Arabia and Damanhur University (DU) in Egypt. Results: The study showed that Egyptian and Saudi students with a higher percentage of supportive parent relationships have less risk of drug involvement. In both countries, cigarette smoking was the first substance used. Moreover, factors predicting the risk of drug involvement and regression analysis revealed that male students had five times more risk of drug involvement than their female peers, keeping all other factors constant (OR = 5.734; 95%CI:3.231-10.174), while highly supportive paternal relationship reduced the risk of drug involvement by 85% (OR = 0.148; 95% CI: 0.045-0.489). Conclusion: The risk for substance abuse in both cultural settings was moderate, and smoking was the most common substance used. Moreover, a highly supportive paternal relationship reduced the risk of drug involvement by 85%.
