A Randomized Depression Prevention Trial Comparing Interpersonal Psychotherapy--Adolescent Skills Training to Group Counseling in Schools
No full textGiven the rise in depression disorders in adolescence, it is important to develop and study depression prevention programs for this age group. The current study examined the efficacy of Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST), a group prevention program for adolescent depression, in comparison to group programs that are typically delivered in school settings. In this indicated prevention trial, 186 adolescents with elevated depression symptoms were randomized to receive IPT-AST delivered by research staff or group counseling (GC) delivered by school counselors. Hierarchical linear modeling examined differences in rates of change in depressive symptoms and overall functioning from baseline to the 6-month follow-up assessment. Cox regression compared rates of depression diagnoses. Adolescents in IPT-AST showed significantly greater improvements in self-reported depressive symptoms and evaluator-rated overall functioning than GC adolescents from baseline to the 6-month follow-up. However, there were no significant differences between the two conditions in onset of depression diagnoses. Although both intervention conditions demonstrated significant improvements in depressive symptoms and overall functioning, results indicate that IPT-AST has modest benefits over groups run by school counselors which were matched on frequency and duration of sessions. In particular, IPT-AST outperformed GC in reduction of depressive symptoms and improvements in overall functioning. These findings point to the clinical utility of this depression prevention program, at least in the short-term. Additional follow-up is needed to determine the long-term effects of IPT-AST, relative to GC, particularly in preventing depression onset.The final publication is available at Springer via http://dx.doi.org/10.1007/s11121-015-0620-5Peer reviewe
Mutations in the Aeromonas salmonicida subsp. salmonicida type III secretion system affect Atlantic salmon leucocyte activation and downstream immune responses
No full textDeletion mutants of Aeromonas salmonicida subsp. salmonicida were used to determine the effect of the type three secretion system (TTSS) on Atlantic salmon anterior head kidney leucocytes (AHKL). One strain had a deletion in the outer membrane pore gene, ascC; and the other in three effector genes: aopO, aopH and aexT (we call this strain Δaop3). Host cell invasion success and 24h survival were depressed in ΔascC, as was 24h survival of Δaop3, when compared to the wild type strain. Challenge of AHKLs with A449 or TTSS mutants stimulated expression of the inflammatory mediators IL-8, IL-1 and TNFα at two bacterial concentrations (A600 0.1, 0.01). Expression of IL-12 was not stimulated in ΔascC challenged cells, whereas A449 and Δaop3 challenge resulted in an up-regulation of IL-12 in AHKLs, 2- and 4-fold higher than PBS, respectively. Only the wild type strain elicited a significant increase in IL-10 expression (5.5× at A600 0.1). Inducible nitric oxide synthetase (iNOS) and arginase (I+II) genes were also significantly up-regulated upon exposure to all strains. However, iNOS:arginase ratio was elevated in the effector mutant challenge. These results suggest that A. salmonicida subsp. salmonicida may enhance survival within the host cell through polarization of macrophages/leucocytes to an alternative, rather than classical, activation state. Furthermore, the short-term survival and lack of T-cell signalling cytokine stimulation in ΔascC, may help explain its inefficiency at providing protection to subsequent wild type challenge.ID: S1050464809002988; M3: Article; Accession Number: S1050464809002988; Author: Mark D.

Behavioral ecology and population genetics of two populations of blue crab, Callinectes sapidus (Rathbun), in New Jersey:
No full textBlue crabs are important estuarine organisms, both ecologically and economically. Due to historical differences of human impact between contaminated Hackensack Meadowlands (HM) and cleaner Tuckerton (TK), adult prey capture, juvenile predator avoidance, adult/juvenile aggression, metal accumulation/depuration and population genetics were investigated.HM adults had reduced prey capture on active prey compared to TK crabs, suggesting HM crabs may have reduced coordination. Stomach analysis revealed HM crabs’ stomachs contained ~60% algae/plant and detritus/sediment, and lower crab and fish weights than TK crabs. TK crabs were caged in HM or fed HM food for 8 weeks; their prey capture declined significantly indicating environmental factors were responsible for the behavioral differences. Crabs were then analyzed for metals in muscle and hepatopancreas. HM crabs were fed clean food or transplanted to TK; TK crabs were fed contaminated food or transplanted to HM. Significant tissue differences were found for Cu, Hg, Pb and Zn. HM crabs did not show a significant decrease in Hg after switching environment or diet, but showed a significant decrease in Cu, Pb and Zn in hepatopancreas after switching. TK crabs showed a significant increase of Hg in muscle and Cr and Zn in hepatopancreas after switching environment or food. In the lab, HM juveniles attacked threatening stimuli significantly more and TK juveniles fled or gave a mixed response significantly more. HM juveniles were significantly better at avoiding a crab predator when substrate was present. Follow-up experiments were conducted without substrate to determine if aggression was important. Aggressive juveniles were no more successful than non-aggressive ones at avoiding a predator. Adults were placed in a large tank with a crab pot; significantly fewer HM adults entered the pot. The first HM crab to enter generally prevented others from entering or attacked those that did, suggesting aggression may be causing low pot counts. Microsatellites were analyzed using four markers. Genotypic differences were not found among the three years which indicates these populations are not genetically distinct. Yearly differences were not found. These results indicate genetics can be ruled out. The ‘switch’ experiments results indicate the environment is causing the behavioral differences.Ph.D.Includes bibliographical references (p. 108-121)by Jessica M. Reichmut

Voice in devising/devising through voice: A conversation with Mikhail Karikis, Elaine Mitchener and Jessica Walker
No full textThis is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.How is voice used in devising practices? What is the interplay between structure, freedom
and improvisation in such compositional practices? In what ways is voice conceived and
practised as material? In providing answers to such questions, this multi-vocal
interview/roundtable transcript is composed around the responses of three contemporary
vocal artists based in the United Kingdom, Mikhail Karikis, Elaine Mitchener and Jessica
Walker. Their work ranges from audio-visual installations and solo shows to immersive
performance and site-responsive work, and their deployment of vocality ranges from jazz and
Victorian music hall repertoires to extended vocal techniques and experimentations across
the speech–song continuum. In conversation with practitioner-scholar Konstantinos
Thomaidis, their responses offer valuable insights into current vocal experimentation but are
also an invitation to expand discussions around devising in the field of interdisciplinary voice

Teacher Locus of Control and Teacher Self-Efficacy of Agricultural Educators in Southeast Missouri
No full textThis study sought to describe the self-efficacy, locus of control (LOC), sex, age, teaching experience, and number of teaching partners of school-based agricultural educators (SBAE) in Southeast Missouri and the relationships between those variables. A census of teachers in the district was conducted using the Teacher Self-Efficacy Scale and Teacher Locus of Control Scale during district Career Development Event competitions. Descriptive and inferential statistical tests were used to analyze data. The average SBAE teacher in Southeast Missouri is male, 38 years old, has taught for 12 years, is in a single teacher program, has a high teacher self-efficacy, and external teacher locus of control beliefs. Although self-efficacy was not found to hold statistically significant correlations with LOC, relationships with age and experience level were statistically significant. The SBAE teachers' LOC differed based on their age, experience level, and program type. Male and females were found to be statistically significantly different in age, experience, and number of co-teachers. A relationship was found between the SBAE teachers' age and each of the research variables. No other relationships were deemed statistically significant. In Southeast Missouri, as male SBAE teachers in single programs age and gain experience, they gain self-efficacy and become more external in LOC. To improve self-efficacy of younger teachers, SBAE leaders in Southeast Missouri should create a coaching and mentoring program to follow Bandura's modeling social learning theory. Researchers should develop an instrument to assess the LOC of SBAE teachers and compare the data across populations. Additional research is necessary in agricultural education literature to understand fully these results.Agricultural Educatio
