Indirect Bullying and Conflict Management Skills in Childhood and Adolescence

In this study, the Young Adult Social Behavior Scale (YASB) and Conflict Resolution Scale (CRS) measures were administered to students from three private middle and high schools in the mid-Atlantic US as part of a larger study regarding the effects of a group counseling curriculum in reducing forms of indirect bullying. Research questions were developed to evaluate differences according to student age and gender in relational aggression, social aggression, and interpersonal maturity, as well as relationships between relational aggression, social aggression, interpersonal maturity, and conflict resolution skills. These questions were evaluated using MANOVA, Chi-square, and multivariate regression analyses, respectively. Results of these analyses suggested that in this sample, there were no mean differences in age and gender on the self-reported use of relational aggression, social aggression, and interpersonal maturity. However, there was an associative relationship between higher age and significantly elevated relational aggression scores. There was also an associative relationship between gender (e.g., males) and significantly elevated scores on the social aggression scale. Finally, multivariate regression analysis indicated that relational and social aggression did not predict difficulties with conflict resolution skills. These results were discussed within the context of the present understanding of the literature

Sex Differences in rt-PA Utilization at Hospitals Treating Stroke: The National Inpatient Sample.

BACKGROUND AND PURPOSE: Sex and race disparities in recombinant tissue plasminogen activator (rt-PA) use have been reported. We sought to explore sex and race differences in the utilization of rt-PA at primary stroke centers (PSCs) compared to non-PSCs across the US. METHODS: Data from the National (Nationwide) Inpatient Sample (NIS) 2004-2010 was utilized to assess sex differences in treatment for ischemic stroke in PSCs compared to non-PSCs. RESULTS: There were 304,152 hospitalizations with a primary diagnosis of ischemic stroke between 2004 and 2010 in the analysis: 75,160 (24.7%) patients were evaluated at a PSC. A little over half of the patients evaluated at PSCs were female (53.8%). A lower proportion of women than men received rt-PA at both PSCs (6.8 vs. 7.5%, p \u3c 0.001) and non-PSCs (2.3 vs. 2.8%, p \u3c 0.001). After adjustment for potential confounders the odds of being treated with rt-PA remained lower for women regardless of presentation to a PSC (OR 0.87, 95% CI 0.81-0.94) or non-PSC (OR 0.88, 95% CI 0.82-0.94). After stratifying by sex and race, the lowest absolute treatment rates were observed in black women (4.4% at PSC, 1.9% at non-PSC). The odds of treatment, relative to white men, was however lowest for white women (PSC OR = 0.85, 95% CI 0.78-0.93; non-PSC OR = 0.80, 95% CI 0.75-0.85). In the multivariable model, sex did not modify the effect of PSC certification on rt-PA utilization (p-value for interaction = 0.58). CONCLUSION: Women are less likely to receive rt-PA than men at both PSCs and non-PSCs. Absolute treatment rates are lowest in black women, although the relative difference in men and women was greatest for white women

Sex Disparities in Access to Acute Stroke Care: Can Telemedicine Mitigate this Effect?

Background: Women have more frequent and severe ischemic strokes than men, and are less likely to receive treatment for acute stroke. Primary stroke centers (PSCs) have been shown to utilize treatment more frequently. Further, as telemedicine (TM) has expanded access to acute stroke care we sought to investigate the association between PSC, TM and access to acute stroke care in the state of Texas. Methods: Texas hospitals and resources were identified from the 2009 American Hospital Association Annual Survey. Hospitals were categorized as: (1) stand-alone PSCs not using telemedicine for acute stroke care, (2) PSCs using telemedicine for acute stroke care (PSC-TM), (3) non-PSC hospitals using telemedicine for acute stroke care, or (4) non-PSC hospitals not using telemedicine for acute stroke care. The proportion of the population who could reach a PSC within 60 minutes was determined for stand-alone PSCs, PSC-TM, and non-PSCs using TM for stroke care. Results: Overall, women were as likely to have 60-minute access to a PSC or PSC-TM as their male counterparts (POR 1.02, 95% CI 1.02-1.03). Women were also just as likely to have access to acute stroke care via PSC or PSC-TM or TM as men (POR 1.03, 95% CI 1.02-1.04). Discussion: Our study found no sex disparities in access to stand alone PSCs or to hospitals using TM in the state of Texas. The results of this study suggest that telemedicine can be used as part of an inclusive strategy to improve access to care equally for men and women

Ego Identity and Relational and Social Aggression Mediated by Elaborative and Deep Processing

Abstract: In this investigation, late adolescents' (N = 629) ego identity status (e.g., identity achievement, identity diffusion, identity moratorium, and identity foreclosure), cognitive processing style, and self-reported use of relational aggression and social aggression were measured in order to assess potential relationships among these constructs. Four separate models were used to test these hypotheses, and the results showed support for some but not all the four hypotheses. In this sample, it appears that individuals with high levels of cognitive sophistication who lack social maturity by which to resolve relationship problems were more likely to use social aggression than those with lower levels of cognitive processing skills or with higher levels of emotional maturity

A fine structural study of divalent cation-mediated epithelial union with connective tissue in human oral mucosa

Following incubation in an isotonic saline solution containing 20 mM EDTA, human oral mucosa may be separated into its epithelial and connective tissue components. Ultrastructural study of the separated tissues reveals that the plane of separation is through the lamina lucida. Hemidesmosomal structure is altered by the separation process: the peripheral density is absent but a fine, generally filamentous material remains associated with the outer membrane leaflet of the hemidesmosome. Desmosome structure is not altered. An intact lamina densa remains attached to the connective tissue fragment. Oral mucosa incubated in EDTA-saline containing calcium, or its return to a divalent cation-supplemented medium after treatment with EDTA, prevents separation. By maintaining the structural integrity of the hemidesmosome, divalent cations appear to play a principal role in uniting oral mucosal epithelium to the lamina propria.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/49659/1/1001330406_ftp.pd

SERA: Simulation Environment for Radiotherapy Applications - Users Manual Version 1CO

This document is the user manual for the Simulation Environment for Radiotherapy Applications (SERA) software program developed for boron-neutron capture therapy (BNCT) patient treatment planning by researchers at the Idaho National Engineering and Environmental Laboratory (INEEL) and students and faculty at Montana State University (MSU) Computer Science Department. This manual corresponds to the final release of the program, Version 1C0, developed to run under the RedHat Linux Operating System (version 7.2 or newer) or the Solaris™ Operating System (version 2.6 or newer). SERA is a suite of command line or interactively launched software modules, including graphical, geometric reconstruction, and execution interface modules for developing BNCT treatment plans. The program allows the user to develop geometric models of the patient as derived from Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) images, perform dose computation for these geometric models, and display the computed doses on overlays of the original images as three dimensional representations. This manual provides a guide to the practical use of SERA, but is not an exhaustive treatment of each feature of the code
