Looking back: the experience of first sexual intercourse and current sexual adjustment in young heterosexual adults

A young person's first consensual sexual intercourse experience is often a remarkable and memorable experience. However, little systematic information exists regarding contextual factors of first intercourse, the affective salience of the experience, possible effects on sexual attitudes and beliefs, and subsequent sexual development and adjustment. This retrospective study aimed to examine these in a sample of 475 young adults. Overall, young men and women experienced intercourse for the first time around age 17, were in a committed relationship, and reported positive affective responses. Affective reactions to the first sexual intercourse experience, sexual self-efficacy, sexual aversion, and age at first intercourse affected individuals' current sexual adjustment; however, only sexual self-efficacy mediated between first intercourse and current sexual adjustment in young men and women. Older age at first intercourse was associated with less sexual self-efficacy and lower current sexual adjustment for women. This study provides initial data to suggest that the first sexual intercourse experience significantly impacts current sexual adjustment by affecting beliefs about sexual self-efficacy.     

Assessing state substance abuse prevention infrastructure through the lens of CSAP's Strategic Prevention Framework

Although the organizational structures and operating procedures of state substance abuse prevention systems vary substantially across states, there is scant empirical research regarding approaches for rigorous assessment of system attributes and which attributes are most conducive to overall effectiveness. As one component of the national cross-site evaluation of the SPF State Incentive Grant Program (SPF SIG), an instrument was developed to assess state substance abuse prevention system infrastructure in order to measure infrastructure change and examine the role of state infrastructure in achieving prevention-related outcomes. In this paper we describe the development of this instrument and summarize findings from its baseline administration. As expected, states and territories were found to vary substantially with respect seven key characteristics, or domains, of state prevention infrastructure. Across the six domains that were assessed using numeric ratings, states scored highest on data systems and lowest on strategic planning. Positive intercorrelations were observed among these domains, indicating that states with high capacity on one domain generally have relatively high capacity on other domains as well. The findings also suggest that state prevention infrastructure development is linked to both funding from state government and the presence of a state interagency coordinating body with decision-making authority. The methodology and baseline findings presented will be used to inform the ongoing national cross-site evaluation of the SPF SIG and may provide useful information to guide further research on state substance abuse prevention infrastructure.     

Children and Families’ Involvement in Social Work Decision Making

This review summarises the research literature on children’s and parents’ involvement in social work decision making, which is regarded, in policy terms, as increasingly important. In practice, however, it tends to be messy, difficult and compromised. Different individuals or groups may have different understandings of participation and related concepts, while differences of age and disability also mediate effective user engagement. The literature highlights common themes in effective participatory practice with both children and their parents. Central to this are the establishment of relationships of trust and respect, clear communication and information and appropriate support to participate.     

Water sources of urban trees in the Los Angeles metropolitan area

In semi-arid cities, urban trees are often irrigated, but may also utilize natural water sources such as groundwater. Consequently, the sources of water for urban tree transpiration may be uncertain, complicating efforts to efficiently manage water resources. We used a novel approach based on stable isotopes to determine tree water sources in the Los Angeles basin, where we hypothesized that trees would rely on irrigation water in the soil rather than develop deep roots to tap into groundwater. We evaluated the oxygen (δ¹⁸O) and hydrogen (δD) isotope ratios of xylem water, irrigation water, soil water, and groundwater in a study of temporal patterns in water sources at two urban sites, and a study of spatial patterns at nine urban sites and one “natural” riparian forest. Contrary to our hypothesis, we found that despite frequent irrigation, some trees tap into groundwater, although in most species this was a small water source. Some trees appeared to be using very shallow soil water at <30 cm depth, suggesting that these mature urban trees were quite shallowly rooted. In the natural site, trees appeared to be using urban runoff in addition to shallow soil water. We were able to identify tree uptake of precipitation at only 3 sites. The results show that some irrigated trees utilize groundwater and do not rely solely on irrigation water, which may make them able to withstand drought and/or water conservation measures. However, some irrigated trees may develop very shallow root systems, which may make them more susceptible.     

Schulman's urban lesbian: a hobosexual pedestrian rhetoric

The following article reads the protagonist in Sarah Schulman's Girls, Visions and Everything as not only lesbian, but as hobosexual-a concept representative of anti-capitalist practices in both sex and labor. The hobosexual is developed as an extension of the lesbian flaneur, as a concept that requires reading Schulman's urban lesbian at the intersection of class and sexuality. Lila Futuransky's sexual identity is suspended and complicated through an emphasis on her desire for queer mobility; her urban movements connect her to hobo history, but also expose the effects of capitalism that thwart her urban movement.
