Bionomics of two forensically important blowfly species Chrysomya megacephala and Chrysomya putoria (Diptera: Calliphoridae) reared on four types of diet

The use of heterogeneous animal tissues for the rearing of necrophagous insect species can produce uneven biological data, which can compromise the determination of larval age and, consequently, estimates for post-mortem intervals. We investigated the development of two species, Chrysomya megacephala and Chrysomya putoria (Diptera: Calliphoridae), reared on four substrates: minced beef (control) and semi-synthetic diets with the addition of sardine, rumen or chicken eggs. No differences in total developmental times were detected among larvae reared on different diets. Length and width of larvae were partially affected by the type of food. Third instar larvae and pupae of both species were heavier on beef treatment when compared with other substrates. Overall mortality was lower when beef was used as food. Longevity of adults and sex ratio were not negatively affected by the use of diets. Egg-based diet was the least effective for both species. Given the fact that several bionomical parameters of larvae reared on diets were close to those obtained when minced beef was offered, and considering the putrid odour, frequency of contamination and lack of homogeneity of animal tissue, semi-synthetic diets can be used for rearing C. megacephala and C. putoria.     

Interstate Communication Among State Legislators Regarding Energy Policy Innovation

This study, using survey data of legislators in six states,examines the prevalence of cross-state cue-taking. The findingsregarding the sources of policy ideas are similar to those reportedin studies of agency officials. Regionalism is most important,although a few states are recognized as national leaders. Supportfor innovative energy policies among state legislators was positivelyrelated to two variables: the extent to which one engaged incue-taking and the degree to which the respondents were supportiveof external communication. A comparison of the six states showsthat extensive interstate communication is not a necessary conditionfor legislative support of innovative policies; an orientationsupportive of external cue-taking is sufficient.     

Competency to stand trial: description and initial evaluation of a new computer-assisted assessment tool (CADCOMP).

The authors describe a Computer-Assisted Determination of Competency to Proceed (CADCOMP), a new instrument that collects data directly from the defendant through an interactive computer program and renders a report covering relevant historical, psychopathological, and legal information. The comprehensive report could be utilized by the clinician to focus the clinician's interview with the defendant on areas requiring further probing, thus reducing the time required to assess competency. Preliminary reliability and validity assessment studies are reported. The results support the predictive validity of CADCOMP used as a screening instrument and found the CADCOMP to be sufficiently reliable to be used for screening purposes.     

Mother-daughter dyads view the family: Associations between divergent perceptions and daughter well-being

Divergent perceptions (or disagreements) within the mother-daughter dyad and the association of such divergence with daughter's affective and behavioral well-being were examined in the current study. One hundred sixty-one mother-daughter dyads (daughters aged 14–18 years; mothers aged 37–59 years) completed paper- and-pencil measures assessing their perceptions of family cohesion and family conflict; daughters also rated their own depressive affect and dieting behavior. While the means for groups of mothers and daughters on family cohesion and conflict were similar, dyads varied substantially in their level of agreement. Disagreements on family cohesion were associated with daughter dieting behavior; maternal employment status was more highly associated with daughter depressive affect than either family conflict or cohesion. Findings are discussed in terms of their implications for studying the divergent perceptions of family members, and for family systems and relationship approaches to understanding the family.The research presented in this paper was supported by the W.

Binge eating in anorexia nervosa predicts later onset of substance use disorder: A ten-year prospective,longitudinal follow-up of 95 adolescents

The cooccurrence of binge eating and increased alcohol intake and substance abuse has been reported in clinical and community epidemiological samples. To further investigate the nature and causes of this comorbidity, we examined the 10-year prospective, longitudinal course of illness in 95 nonsubstance abusing adolescents hospitalized for treatment of anorexia nervosa. Survival analysis with Cox regression was used to quantitate the cumulative risk of developing substance use disorder (SUD) as a function of patterns of binge eating vs. dietary restraint within this cohort. Subjects who were binge eating at the time of intake were robustly distinguished from restrictors, having increased risk of SUD as well as greater likelihood of having at least one first-degree relative with SUD. The findings suggest binge eating that develops in the underweight stage of anorexia nervosa may reflect developmental, biological, and genetic risk processes shared in common with SUD.Received Ph.D. in clinical psychology from the University of Pittsburgh.
