Purpose
The purpose of this study was to test the feasibility, usability, and acceptability of implementing a web-based method for collecting social network and longitudinal daily interaction data ...from cancer survivors and their caregivers.
Methods
Young adult and sexual/gender minority cancer survivors and their informal caregivers were recruited as dyads. Feasibility data, including enrollment and retention, were captured. Individual social network data were collected at baseline and used to individualize daily electronically delivered surveys assessing characteristics of daily social support-related interactions with identified network members for 14 days. Follow-up questionnaires assessing usability and exit interviews assessing acceptability were completed at the end of the 2-week study period.
Results
Fourteen survivor-caregiver dyads (28 individual participants) were enrolled and completed all baseline and final measures. Participants completed 85.2% of daily diary reports and reported excellent usability ratings. Acceptability was also high. In qualitative interviews, participants reported enjoying the daily reflection on social support facilitated by our methods.
Conclusions
Our method has been shown to be highly feasible, usable, and acceptable.
Implications for Cancer Survivors
Developing better data collection tools can lead to better understanding of the social support cancer survivors and their caregivers receive, and how the social network structure facilitates or creates barriers to accessing this support.
Background
Peer bullying is associated with internalizing problems for children and adolescents. However, less is known about how these same behaviors are related to student well-being when they ...occur within the context of the sibling relationship and how supportive behavior may benefit those experiencing bullying.
Objective
The purpose of this study was to examine the unique associations among peer and sibling bullying and internalizing problems, and the role of peer and sibling social support in relation to social-emotional outcomes.
Methods
Data on students’ experiences of peer and sibling bullying, perceptions of social support and internalizing symptoms were collected from a sample of 372 elementary school students using the Revised Olweus Bully/Victim Questionnaire (OBVQ; Olweus
1996
), a modified version of the OBVQ created to assess bullying by siblings, the Child and Adolescent Social Support Scale (CASSS; Malecki et al.
2000
), and three subscales from the Behavior Assessment System for Children, Second Edition, Self-Report of Personality (Reynolds and Kamphaus
2004
).
Results
Results indicated that Sibling Bullying was significantly related to internalizing problems above and beyond Peer Bullying alone. Additionally, social support from peers moderated the association between Sibling Bullying and Depression; and social support from siblings moderated the association between Peer Bullying and Social Stress. Gender differences in study findings were also uncovered.
Conclusions
Results of this study suggest that bullying behaviors are detrimental to student social-emotional well-being, regardless of whom the perpetrator may be, and that being bullied by siblings is associated with similar outcomes as traditional bullying.
Bullying is a process of direct (i.e., youth who bully and are victimized) and indirect (i.e., bystanders) social exchanges. Though researchers often examine social and emotional correlates of ...bullying role behaviors, it is important to also consider the underlying cognitive processes associated with different bullying roles such as socially oriented cognitive processes associated with executive functions. The goal of the current study was to examine executive functions associated with types of bullying role behavior (aggression, victimization, defending, assisting, and outsider behavior) and differences between boys and girls within a sample of 689 third- to eighth-grade students (51% male, 49% female). Victimization was significantly and negatively associated with each executive function. Defending was positively associated with emotion regulation for upper elementary school students, but not for middle school students. Outsider behavior was significantly and negatively associated with self-monitoring, flexibility, and initiation.
Abstract
As part of the hazard and risk assessment of chemicals in man, it is important to assess the ability of a chemical to induce mutations in vivo. Because of the commonalities in the molecular ...initiating event, mutagenicity in vitro can correlate well to the in vivo endpoint for certain compound classes; however, the difficulty lies in identifying when this correlation holds true. In silico alerts for in vitro mutagenicity may therefore be used as the basis for alerts for mutagenicity in vivo where an expert assessment is carried out to establish the relevance of the correlation. Taking this into account, a data set of publicly available transgenic rodent gene mutation assay data, provided by the National Institute of Health Sciences of Japan, was processed in the expert system Derek Nexus against the in vitro mutagenicity endpoint. The resulting predictivity was expertly reviewed to assess the validity of the observed correlations in activity and mechanism of action between the two endpoints to identify suitable in vitro alerts for extension to the in vivo endpoint. In total, 20 alerts were extended to predict in vivo mutagenicity, which has significantly improved the coverage of this endpoint in Derek Nexus against the data set provided. Updating the Derek Nexus knowledge base in this way led to an increase in sensitivity for this data set against this endpoint from 9% to 66% while maintaining a good specificity of 89%.
Objective. To assess the effect of a dental clinical rotation program involving pharmacy students and dental students.
Methods. An interprofessional education (IPE) course was offered as an elective ...to second-year pharmacy students and required for third-year dental students. The course included two in-class sessions, one online lecture, and five clinic sessions. Program evaluation analyses included a comparison of participating versus nonparticipating students on a knowledge survey of pharmacotherapy and IPE, and a descriptive analysis of IPE course evaluation results.
Results. Among pharmacy students, mean scores were significantly higher for participants than nonparticipants on the 31-item pharmacy knowledge component of the survey. On the eight-item IPE component of the survey, scores were significantly higher for participants than for nonparticipants, both among pharmacy students and among dental students. Awareness and attitudes about IPE were generally high among course participants.
Conclusion. An IPE course that integrates second-year pharmacy students with third-year dental students in the dental clinic to provide medication history, education, and identification of potential drug-related problems improved pharmacy students’ knowledge of pharmacotherapy related to or associated with dental conditions and improved pharmacy and dental students’ knowledge and attitudes about IPE.
Regional volcanic threat assessments provide a large-scale comparable vision of the threat posed by multiple volcanoes. They are useful for prioritising risk-mitigation actions and are required by ...local through international agencies, industries and governments to prioritise where further study and support could be focussed. Most regional volcanic threat studies have oversimplified volcanic hazards and their associated impacts by relying on concentric radii as proxies for hazard footprints and by focussing only on population exposure. We have developed and applied a new approach that quantifies and ranks exposure to multiple volcanic hazards for 40 high-threat volcanoes in Southeast Asia. For each of our 40 volcanoes, hazard spatial extent, and intensity where appropriate, was probabilistically modelled for four volcanic hazards across three eruption scenarios, giving 697 080 individual hazard footprints plus 15 240 probabilistic hazard outputs. These outputs were overlain with open-access datasets across five exposure categories using an open-source Python geographic information system (GIS) framework developed for this study (https://github.com/vharg/VolcGIS, last access: 5 April 2022). All study outputs – more than 6500 GeoTIFF files and 70 independent estimates of exposure to volcanic hazards across 40 volcanoes – are provided in the “Data availability” section in user-friendly format. Calculated exposure values were used to rank each of the 40 volcanoes in terms of the threat they pose to surrounding communities. Results highlight that the island of Java in Indonesia has the highest median exposure to volcanic hazards, with Merapi consistently ranking as the highest-threat volcano. Hazard seasonality, as a result of varying wind conditions affecting tephra dispersal, leads to increased exposure values during the peak rainy season (January, February) in Java but the dry season (January through April) in the Philippines. A key aim of our study was to highlight volcanoes that may have been overlooked perhaps because they have not been frequently or recently active but that have the potential to affect large numbers of people and assets. It is not intended to replace official hazard and risk information provided by the individual country or volcano organisations. Rather, this study and the tools developed provide a road map for future multi-source regional volcanic exposure assessments with the possibility to extend the assessment to other geographic regions and/or towards impact and loss.
In the last few years Rockwell has developed a novel simultaneous unipolar multispectral integrated HgCdTe detector and focal plane array technology that is a natural and relatively straightforward ...derivative of our baseline double layer planar heterostructure (DLPH) molecular beam epitaxial (MBE) technology. Recently this technology was awarded a U.S. patent. This simultaneous unipolar multispectral integrated technology (SUMIT) shares the high performance characteristics of its DLPH antecedent. Two color focal plane arrays with low-1013 cm−2s−1 background limited detectivity performance (BLIP D*) have been obtained for mid-wave infrared (MWIR, 3–5 m) devices at T>130 K and for long-wave infrared (LWIR, 8–10 m) devices at T∼80 K.
The James Webb Space Telescope (JWST) is the successor to the Hubble Space Telescope. JWST will be an infrared-optimized telescope, with an approximately 6.5 m diameter primary mirror, that is ...located at the Sun-Earth L2 Lagrange point. Three of JWST’s four science instruments use Teledyne HgCdTe HAWAII-2RG (H2RG) near infrared detector arrays. During 2010, the JWST Project noticed that a few of its 5 μm cutoff H2RG detectors were degrading during room temperature storage, and NASA chartered a “Detector Degradation Failure Review Board” (DD-FRB) to investigate. The DD-FRB determined that the root cause was a design flaw that allowed indium to interdiffuse with the gold contacts and migrate into the HgCdTe detector layer. Fortunately, Teledyne already had an improved design that eliminated this degradation mechanism. During early 2012, the improved H2RG design was qualified for flight and JWST began making additional H2RGs. In this article, we present the two public DD-FRB “Executive Summaries” that: (1) determined the root cause of the detector degradation and (2) defined tests to determine whether the existing detectors are qualified for flight. We supplement these with a brief introduction to H2RG detector arrays, some recent measurements showing that the performance of the improved design meets JWST requirements, and a discussion of how the JWST Project is using cryogenic storage to retard the degradation rate of the existing flight spare H2RGs.
