Consistency of spectroscopic factors from (e,e'p) reactions at different momentum transfers

The possibility to extract relevant information on spectroscopic factors from (e,e$'$p) reactions at high $Q^2$ is studied. Recent ${}^{16}$O(e,e$'$p) data at $Q^2 = 0.8$ (GeV/$c)^2$ are compared to a theoretical approach which includes an eikonal description of the final-state interaction of the proton, a microscopic nuclear matter calculation of the damping of this proton, and high-quality quasihole wave functions for $p$-shell nucleons in ${}^{16}{\rm O}$. Good agreement with the $Q^2 = 0.8$ (GeV/$c)^2$ data is obtained when spectroscopic factors are employed which are identical to those required to describe earlier low $Q^2$ experiments.Comment: 17 pages, 6 figures in .eps format, submitted to Phys.

Supporting resilience in chldren and youth impacted by complex trauma

Exposure to repeated traumatic events, including abuse, neglect, and domestic and community violence is often referred to as complex trauma. This research was conducted to better understand the developmental impact of complex trauma on children and adolescents, and to consider what treatment approach might best serve this population. The author first examined the impact of repeated victimization on child neurobiological development, with particular attention to the areas of attachment, affect regulation, behavioral control, cognition, and self-esteem. Complex trauma treatments that are more individually focused and grounded in cognitive-behavioral theory were then compared to those that are more systems-focused and stem from attachment and intersubjective theories. This author found that most of the literature agrees on the following core components of treatment for youth with complex trauma histories: safety, selfregulation, self-reflective information processing, traumatic experiences integration, and relational engagement. An area that seems to be getting increasing attention is treatment directed at fostering strengths and building competencies. The author concluded that including a caregiver in as much of the treatment as possible can support attachment and lead to longer-term positive gains. The author found that both approaches offer potentially effective interventions, and combining components from both can result in a more comprehensive treatment approach. This study includes a case example and a discussion of implications for clinical social work practice with a focus on cultural considerations as well as recommendations for further research

A Comparison of State and Local Welcome Center Visitors: Issues Regarding Sampling Frame Generalizability

Tourism is an important industry in the United States and for more regional economies, motivating research exploring characteristics of tourist consumers and their travel behavior. This paper deals with the issue of sampling frame generalizability for tourism research. Visitors to state and local welcome centers were compared in terms of their area awareness, respondent and travel party demographics, and expenditures. Significant differences were found between the groups, questioning the generalizability of data collected at state welcome centers

Inducible Resistance to Pyrethroid Insecticide is Lacking in Adult Aedes aegypti Mosquitoes

Mosquitoes have evolved increased resistance to pyrethroid insecticides including permethrin, and studying their metabolic mechanisms of resistance is the window to human counteraction. If early exposure to insecticides can upregulate certain detoxification genes, this creates lower rates of mortality in a single mosquito’s lifetime. Yellow fever mosquitoes (Aedes aegypti) were exposed to a sublethal dosage of permethrin and mortality rates at a later LC50 dose exposure were recorded. Mortality rates of induced mosquitoes were not lower than the mortality rates of unexposed (control) mosquito groups. If early exposure did not increase mortality, either evidence for inducible same-generational resistance remains to be seen in Aedes aegypti, or other factors were responsible for under-stimulating inducible resistance that were not acknowledged in the experimental design. The experiment may be replicated with adjusted test intervals to find the exact interval at which the upregulated proteins are still active and can confer resistance
