Human mobility and environmental degradation: Shaping rural Morocco

Environmental degradation constitutes a disruptive force in man-made and natural systems. The projected duplication of the frequency and duration of meteorological drought will contribute to a situation of water scarcity, which is expected to negatively impact the agricultural sector. This study focuses on Souss-Massa, Morocco, a leading agricultural region, and it seeks to map how human mobility fits within a wider adaptation response to environmental degradation. Over 30 semi-structured interviews were conducted with internal migrants and members of rural communities on the perceived impacts of environmental degradation and human mobility. Most of the interviewees perceive a reduction in the available water, and the agricultural sector is the most severely affected by those changes. Internal migration is the most frequent adaptation strategy mentioned, and the remittances it originates are supporting the communities of origin facing a deterioration of agricultural output.     

Enhancing the Effectiveness of Practicum Instruction: An Empirical Study

Practicum instructors play a strategic role in assisting students gain the competence essential to effective practice. This article reports on a comparative study that tested the efficacy of traditional and experimental competency-based/task-centered methods of practicum instruction. It revealed that students taught under the latter method performed at a higher overall level of competence and had more confidence in their skills than those taught under the traditional method.     

Differences between Sexually Victimized and Nonsexually Victimized Male Adolescent Sexual Abusers: Developmental Antecedents and Behavioral Comparisons

This study compares sexually victimized and nonsexually victimized male adolescent sexual abusers on a number of variables. Self-report measures were administered to 325 male sexually abusive youth (average age 16) in six residential facilities in the Midwest, 55% of whom reported sexual victimization. The results indicate that the sexually victimized sexual abusers have more severe developmental antecedents (trauma, family characteristics, early exposure to pornography and personality) and recent behavioral difficulties (characteristics of sexual aggression, sexual arousal, use of pornography, and nonsexual criminal behavior) than the nonsexually victimized group. Results are contrasted with recent typological research, which found no relationship between sexual victimization and subtype membership. Treatment, research, and theoretical implications are discussed.     

Talking as a primary method of peer defusing for military personnel exposed to combat trauma

1. Humanitarian relief missions and military operations are unquestionably stressful and clearly have potential to affect the mental health of soldiers. 2. After being exposed to traumatic events, soldiers may develop acute stress reactions, a historically known phenomenon better recognized and understood today. 3. Although organized resources exist, they may not be accessible or appropriate. Soldiers are the most precious asset the military forces have and their peers may be the best and only resource available to them. 4. The need to ventilate and the relief that follows after talking about distressing events are evidence that defusing by talking should be encouraged after exposure to a traumatic event.     

Routes of Chloroform Exposure and Body Burden from Showering with Chlorinated Tap Water

While there is an awareness of the need to quantify inhalation exposure from showers, the potential for dermal exposure to organic contaminants in showers has not been appreciated or explored. To establish routes of environmental exposure from showers, comparisons of the concentration of chloroform in exhaled breath after a normal shower with municipal tap water were made with those after an inhalation-only exposure. The postexposure chloroform breath concentrations ranged from 6.0-21 micrograms/m3 for normal showers and 2.4 to 10 micrograms/m3 for inhalation-only exposure, while the pre-exposure concentrations were all less than the minimum detection limit of 0.86 micrograms/m3. According to an F-test, the difference between the normal shower and the inhalation-only exposures was considered significant at a probability of p = 0.0001. Based on the difference, the mean internal dose due to dermal exposure was found to be approximately equal to that due to the inhalation exposure. The effect of the showering activities on the concentration of chloroform shower air was examined by comparing air concentrations during a normal shower with the air concentrations obtained when the shower was unoccupied. The F-test showed that there is no significant difference between the two sets of data.     

Passive versus active parental permission in school-based survey research: does the type of permission affect prevalence estimates of risk behaviors?

This study investigates whether the type of parental permission affects prevalence estimates for risk behaviors from the national 2001 Youth Risk Behavior Survey. Participants were 13,195 students from 143 schools, of which 65% used passive permission and 35% active permission. Student participation rates were 86.7% in passive permission schools and 77.3% in active permission schools. For 24 of 26 behaviors tested, no significant differences were seen in the prevalence of risk behavior by type of parental permission. As long as high response rates are obtained, type of parental permission does not affect prevalence estimates for risk behaviors that are based on self-report.     

The resources that matter: fundamental social causes of health disparities and the challenge of intelligence

A robust and very persistent association between indicators of socioeconomic status (SES) and the onset of life-threatening disease is a prominent concern of medical sociology. The persistence of the association over time and its generality across very different places suggests that no fixed set of intervening risk and protective factors can account for the connection. Instead, fundamental-cause theory views SES-related resources of knowledge, money, power prestige, and beneficial social connections as flexible resources that allow people to avoid risks and adopt protective strategies no matter what the risk and protective factors are in a given place or time. Recently, however, intelligence has been proposed as an alternative flexible resource that could fully account for the association between SES and health and thereby find its place as the epidemiologists' "elusive fundamental cause" (Gottfredson 2004). We examine the direct effects of intelligence test scores and adult SES in two data sets containing measures of intelligence, SES, and health. In analyses of prospective data from both the Wisconsin Longitudinal Study and the Health and Retirement Survey, we find little evidence of a direct effect of intelligence on health once adult education and income are held constant. In contrast, the significant effects of education and income on health change very little when intelligence is controlled. Although data limitations do not allow a definitive resolution of the issue, this evidence is inconsistent with the claim that intelligence is the elusive fundamental cause of health disparities, and instead supports the idea that the flexible resources people actively use to gain a health advantage are the SES-related resources of knowledge, money, power, prestige, and beneficial social connections.
