The effect of an experiential, adventure based anti-bullying initiative on levels of resilience: A mixed methods study

The purpose of this study was to assess the effect of an experiential, adventure based program on levels of resilience. Specifically, a mixed methods, quasi-experimental design was implemented to measure the impact of an Anti-Bullying Initiative on students self reported Goals and Aspirations, Problem Solving, Empathy, and Self Efficacy traits. Quantitative data was gathered using the Anti-Bullying Initiative Survey and converged with results from focus groups, interviews, and program observations to assess both program outcomes and processes. Results indicated that this adventure education program did affect levels of resilience in the individual students as well as their school and home environments. By identifying resilient outcomes and fostering a safe and supportive environment, this program provided important tools and experiences that appear to have helped enhance the students\u27 internal assets. Continuity between the program and the school contributed to further improve outcomes as valued in the classroom setting. Providing increased levels of responsibility enabled the students to contribute to the external assets available in both school and peer settings. This saturation of assets may have had an impact on home and community environments, working to create more resilient situations in addition to more resilient individuals. Gender differences were noted and deserve further inquiry. The Resilience Cycle, a conceptual model of resilience enhancement, is presented; implications for practice and resilience theory are discussed; and directions for future research are identified

Woody Vegetation of a Disjunct Oak Woodland in East-Central Nebraska.

The woody vegetative composition of the Oak Glen Wildlife Management Area, a disjunct oak woodland in Seward County, Nebraska, was assessed using the Point-Quarter method. Based on data from three size categories, the presettlement composition of the woodland appears to have been a bur oak (Quercus macrocarpa) dominated community which, based on spacing and growth form, may have been savanna-like. Under present management, this community is succeeding to one consisting primarily of elm (Ulmus spp.), and hackberry (Celtis occidentalis

Contact Theory as a Framework for Experiential Activities as Diversity Education: An Exploratory Study

Participation in experiential education is said to enhance people\u27s appreciation for diversity. This article reports on a study that found significant changes in participants\u27 attitudes, beliefs, and behaviors following a nonformal diversity education program using adventure-based and community-service activities. Additionally, hypothesized program conditions, as outlined by contact theory, were significantly predictive of outcomes, although majority and minority participants differed on their perceptions of these conditions. These findings suggest that experiential activities may be considered a viable approach to diversity education in nonformal settings, assuming key conditions are met. Implications for practice and directions for future research are discussed

Woody Vegetation of a Disjunct Bur Oak (Quercus macrocarpa) Forest in East-Central Nebraska

Woody plant composition was assessed for three tree-size classes in two ravines of Oak Glen Wildlife Management Area, a disjunct oak forest in Seward County, Nebraska, using Importance Values (IV) obtained by the Point-Quarter method. Bur oak (Quercus macrocarpa Michx.) dominated the large-size class (\u3e30 cm dbh) (IV = 258) but elms (Ulmus americana L. and U. rubra Muhl.) (IV = 130) dominated the forest in one ravine in the medium-size class (10-30cm dbh) and elm and hackberry (Celtis occidentalis L.) (IV = 114 and 27 respectively) dominated the small-size class

Valsalva maneuver: Insights into baroreflex modulation of human sympathetic activity

Valsalva's maneuver, voluntary forced expiration against a closed glottis, is a well-characterized research tool, used to assess the integrity of human autonomic cardiovascular control. Valsalva straining provokes a stereotyped succession of alternating positive and negative arterial pressure and heart rate changes mediated in part by arterial baroreceptors. Arterial pressure changes result primarily from fluctuating levels of venous return to the heart and changes of sympathetic nerve activity. Muscle sympathetic activity was measured directly in nine volunteers to explore quantitatively the relation between arterial pressure and human sympathetic outflow during pressure transients provoked by controlled graded Valsalva maneuvers. Our results underscore several properties of sympathetic regulation during Valsalva straining. First, muscle sympathetic nerve activity changes as a mirror image of changes in arterial pressure. Second, the magnitude of sympathetic augmentation during Valsalva straining predicts phase 4 arterial pressure elevations. Third, post-Valsalva sympathetic inhibition persists beyond the return of arterial and right atrial pressures to baseline levels which reflects an alteration of the normal relation between arterial pressure and muscle sympathetic activity. Therefore, Valsalva straining may have some utility for investigating changes of reflex control of sympathetic activity after space flight; however, measurement of beat-to-beat arterial pressure is essential for this use. The utility of this technique in microgravity can not be determined from these data. Further investigations are necessary to determine whether these relations are affected by the expansion of intrathoracic blood volume associated with microgravity

Bullying behaviors and victimization experiences among adolescent students: the role of resilience

The role of resilience in the relationship between bullying behaviours, victimisation experiences, and self-efficacy was examined. Three hundred and 93 (191 male, 202 female) adolescents (mean age = 15.88, SD = .64) from schools in Coimbatore, India completed scales to assess bullying behaviours and victimisation experiences, resilience, and self-efficacy. Multigroup SEM, with separate groups created according to participant sex, revealed that resilience mediated the relationship between bullying behaviours and self-efficacy in males. Males engaged in bullying behaviours and experienced victimisation more frequently than females. The findings of the study have implication for designing intervention programs to enhance resilience among adolescents and young adults to enable them to manage bullying behaviours

Inherited DNA-Repair Gene Mutations in Men with Metastatic Prostate Cancer.

Background Inherited mutations in DNA-repair genes such as BRCA2 are associated with increased risks of lethal prostate cancer. Although the prevalence of germline mutations in DNA-repair genes among men with localized prostate cancer who are unselected for family predisposition is insufficient to warrant routine testing, the frequency of such mutations in patients with metastatic prostate cancer has not been established.Methods We recruited 692 men with documented metastatic prostate cancer who were unselected for family history of cancer or age at diagnosis. We isolated germline DNA and used multiplex sequencing assays to assess mutations in 20 DNA-repair genes associated with autosomal dominant cancer-predisposition syndromes.Results A total of 84 germline DNA-repair gene mutations that were presumed to be deleterious were identified in 82 men (11.8%); mutations were found in 16 genes, including BRCA2 (37 men [5.3%]), ATM (11 [1.6%]), CHEK2 (10 [1.9% of 534 men with data]), BRCA1 (6 [0.9%]), RAD51D (3 [0.4%]), and PALB2 (3 [0.4%]). Mutation frequencies did not differ according to whether a family history of prostate cancer was present or according to age at diagnosis. Overall, the frequency of germline mutations in DNA-repair genes among men with metastatic prostate cancer significantly exceeded the prevalence of 4.6% among 499 men with localized prostate cancer (P<0.001), including men with high-risk disease, and the prevalence of 2.7% in the Exome Aggregation Consortium, which includes 53,105 persons without a known cancer diagnosis (P<0.001).Conclusions In our multicenter study, the incidence of germline mutations in genes mediating DNA-repair processes among men with metastatic prostate cancer was 11.8%, which was significantly higher than the incidence among men with localized prostate cancer. The frequencies of germline mutations in DNA-repair genes among men with metastatic disease did not differ significantly according to age at diagnosis or family history of prostate cancer.

Woody Vegetation of a Disjunct Bur Oak (\u3ci\u3eQuercus macrocarpa\u3c/i\u3e) Forest in East-Central Nebraska

Woody plant composition was assessed for three tree-size classes in two ravines of Oak Glen Wildlife Management Area, a disjunct oak forest in Seward County, Nebraska, using Importance Values (IV) obtained by the Point-Quarter method. Bur oak (Quercus macrocarpa Michx.) dominated the large-size class (\u3e30 cm dbh) (IV = 258) but elms (Ulmus americana L. and U. rubra Muhl.) (IV = 130) dominated the forest in one ravine in the medium-size class (10-30cm dbh) and elm and hackberry (Celtis occidentalis L.) (IV = 114 and 27 respectively) dominated the small-size class (\u3c10cm dbh). Bur oak in the small-size was low in abundance (IV = 9) and was absent from one of the study transects. These data on tree-size distribution in the extant forest suggests that the forest is likely to succeed from one presently dominated by bur oak, which appears to have characterized the presettlement forest, to one dominated primarily by elm or hackberry. Current management is likely to encourage a continuation of this succession

Accepting Blame: Expressive Checked Exceptions

Unhandled exceptions crash programs, so a compile-time check that exceptions are handled should in principle make software more reliable. But designers of some recent languages have argued that the benefits of statically checked exceptions are not worth the costs. We introduce a new statically checked exception mechanism that addresses the problems with existing checked-exception mechanisms. In particular, it interacts well with higher-order functions and other design patterns. The key insight is that whether an exception should be treated as a “checked” exception is not a property of its type but rather of the context in which the exception propagates. Statically checked exceptions can “tunnel” through code that is oblivious to their presence, but the type system nevertheless checks that these exceptions are handled. Further, exceptions can be tunneled without being accidentally caught, by expanding the space of exception identifiers to identify the exception-handling context. The resulting mechanism is expressive, syntactically light, and can be implemented efficiently. We demonstrate the expressiveness of the mechanism using significant codebases and evaluate its performance. We have implemented this new exception mechanism as part of the new Genus programming language, but the mechanism could equally well be applied to other programming languages
