Student Agency in Virtual Writing Feedback

This research study explored how student agency is present in virtual writing feedback from their teachers through the theoretical lens of Design. Empirical qualitative results from an online survey suggest that students engage with and push back on academic Discourses through the feedback cycle

Social support and mental health outcomes in battered women

This study examined the relationship between perceived social support and negative mental health outcomes in battered women. Correlations between perceived social support and depression, anxiety, and post-traumatic stress disorder were analyzed. Perceived social support, particularly from family members, was found to be significantly related to mental health outcomes. Results indicate that agencies that work with battered women should include social support in the assessment and intervention processes. The study utilized a quantitative survey design with a sample of 120 battered women from four domestic violence agencies throughout Riverside and San Bernardino counties. Quantitative data analysis procedures, such as multivariate analysis and logistic regression, were used to further examine variables. Samples of the instruments used in the study are included

The Oneida County 4-H Conservation Field Days Conflict

In its 30-year history, New York\u27s Oneida County 4-H Conservation Education Field Days program generated no known controversy. That trend changed radically when a citizens group shot undercover video footage portraying the event as children being brainwashed into thinking guns, hunting and trapping are okay. The video aired statewide and resulted in a national controversy. Oneida County 4-H responded by trying to build consensus among the organizations involved, but discovered that this was not possible. This article relates the events that precipitated this conflict, and examines the various perspectives on the conflict held by the three major organizations involved

Resolving latent conflict: What happens when latent print examiners enter the cage?

Latent print examination traditionally follows the ACE-V process, in which latent prints are first analyzed to determine whether they are suitable for comparison, and then compared to an exemplar and evaluated for similarities and differences. Despite standard operating procedures and quality controls designed, in part, to mitigate differences between examiners, latent print processing and review are inherently subjective. The ACE-V process addresses subjectivity, and the possibility of error, in the verification stage in which a second examiner repeats the analysis, comparison, and evaluation steps in a given case. Other procedures outside the ACE-V framework, such as consultation and conflict resolution, provide further opportunity to understand how differences between latent print examiners emerge. Despite the growing body of research on latent print examination, questions have emerged about how these procedures work in practice. This study reviews case processing data for two years of casework at the Houston Forensic Science Center (HFSC). We describe these data as cases proceed through each step of the ACE-V process, with a particular focus on verification, consultation, and conflict resolution. We discuss trends in these processes regarding modal types of disagreements, modal outcomes, and roles of the examiners involved. Results reveal implications for improving the practice of latent print examination

Using the Theory of Emotional Stakeholders to Experimentally Test the Influence of Proxy Communicators about Organizational Crises in Digital News Reports

The emergence of new and social media has transformed the way that stakeholders and organizations interact between and amongst each other. Online news consumers are now able to directly respond to crisis news reports by offering their own interpretation, thus expanding the diversity of viewpoints audiences are exposed to (Carpenter, 2010; Springer, 2014). Using the Theory of Emotional Stakeholders framework our study aims (1) to understand how positive and negative user-generated comments in response to online news reports of crisis events impacts audience perceptions of organizational blame; (2) to examine the persuasive effects of user comments when expert or official organizational responses are provided; and, (3) to measure the affective response to online news reports including user comments. Using experimental procedures our findings show that user comments from organizations, faith-holders, and hate-holders contribute to audience evaluations of crisis responsibility, both causal and treatment. Results found that user comments from faith-holders reduced causal responsibility in the intentional cluster compared to the control condition; however, when organizations were facing preventable crises, user comments from faith-holders amplified perceived treatment responsibility. A detailed description of the findings, discussion, limitations and future directions are provided

Global Entrepreneurship Monitor Special Report : A Global Perspective on Entrepreneurship Education and Training

In 2008 the Global Entrepreneurship Monitor set out to investigate the prevalence and sources of entrepreneurship education and training, and the effect of this training on starting a business. Thirty-eight national teams participated in this study, adding specialized questions to the standard GEM Adult Populations Surveys (APS). In addition, 30 countries added questions to the National Expert Surveys (NES). This report expands on the eight-page education and training section found on pages 41-48 of the Global Entrepreneurship Monitor 2008 Executive Report. After a brief literature review, we present expert opinions on the current state of entrepreneurship education and training in 30 countries. The report then details the level and sources of training received by the adult population (18-64) in the 38 countries surveyed by GEM. By examining data from the APS, GEM is able to develop profiles of individuals most and least likely to have received training. Additionally, we present new information on the effects of training on an individual’s entrepreneurial awareness, attitudes, intentions and activity in each of the participating countries. Then, five GEM countries provide insights about the types of advisors used by entrepreneurs. The report concludes with possible implications of these new findings and suggests areas for further research

Phenotypic Diversity and Altered Environmental Plasticity in <i>Arabidopsis thaliana</i> with Reduced Hsp90 Levels

The molecular chaperone HSP90 aids the maturation of a diverse but select set of metastable protein clients, many of which are key to a variety of signal transduction pathways. HSP90 function has been best investigated in animal and fungal systems, where inhibition of the chaperone has exceptionally diverse effects, ranging from reversing oncogenic transformation to preventing the acquisition of drug resistance. Inhibition of HSP90 in the model plant Arabidopsis thaliana uncovers novel morphologies dependent on normally cryptic genetic variation and increases stochastic variation inherent to developmental processes. The biochemical activity of HSP90 is strictly conserved between animals and plants. However, the substrates and pathways dependent on HSP90 in plants are poorly understood. Progress has been impeded by the necessity of reliance on light-sensitive HSP90 inhibitors due to redundancy in the A. thaliana HSP90 gene family. Here we present phenotypic and genome-wide expression analyses of A. thaliana with constitutively reduced HSP90 levels achieved by RNAi targeting. HSP90 reduction affects a variety of quantitative life-history traits, including flowering time and total seed set, increases morphological diversity, and decreases the developmental stability of repeated characters. Several morphologies are synergistically affected by HSP90 and growth temperature. Genome-wide expression analyses also suggest a central role for HSP90 in the genesis and maintenance of plastic responses. The expression results are substantiated by examination of the response of HSP90-reduced plants to attack by caterpillars of the generalist herbivore Trichoplusia ni. HSP90 reduction potentiates a more robust herbivore defense response. In sum, we propose that HSP90 exerts global effects on the environmental responsiveness of plants to many different stimuli. The comprehensive set of HSP90-reduced lines described here is a vital instrument to further examine the role of HSP90 as a central interface between organism, development, and environment.</p

A survey of apomixis and ploidy levels among Poa L. (Poaceae) using flow cytometry

Poa is a complex genus taxonomically and genetically. As a result, relatively little information exists for this economically important genus with regards to reproductive mode and variability in chromosome number. We examined apomixis frequency and ploidy levels in 83 Poa accessions representing 33 species from the National Plant Germplasm System using flow cytometric techniques. In reproductive mode analysis, we analyzed at least three preparations of 50 seeds each from the accessions. In ploidy level analysis, at least three plants of each accession were analyzed. Sixty percent of the species had at least one apomictic or facultative apomictic accession; 40% were sexual. Thirty-three percent of the species had no sexual accessions. Autonomous apomixis was newly identified in P. bactriana and P. bulbosa in addition to it being previously reported in P. nervosa. Poa annua and P. trivialis were identified as obligate sexual, and P. nervosa as obligate apomictic. Two of four P. palustris accessions exhibited facultative apomixis. Ploidy levels among sexually reproducing Poa accessions ranged from 2n = 2x = 14 to 2n = 12x = 84, with most accessions between 2n = 3x = 21 to 2n = 8x = 56. Among apomictic accessions, ploidy levels ranged from 2n = 3x = 21 to 2n = 10x = 70, with most between 2n = 4x = 28 and 2n = 10x = 70. These results emphasize the wide variability in Poa, both among and within species

Case-Control study of Firefighters with documented positive tuberculin skin test results using Quantiferon-TB testing in comparison with Firefighters with negative tuberculin skin test results

BACKGROUND: Phoenix Firefighters have had abnormally high rates of tuberculin skin test (TBST) results on medical surveillance. The objectives of this study were to evaluate our firefighters using QuantiFERON-TB (QFT), comparing the results to their TBST results. METHODS: Using QFT results obtained during the study, we compared previously positive TBST responders (Cases) to negative responders (Controls). We also compared both groups for QFT results for Mycobacterium avium (MA) exposure. RESULTS: QFT effectively monitored our working population. 12.9% of the 148 cases, and 3.2% of the 220 controls had a positive QFT result. Another 14.8% of cases and 4.5% of controls had conditionally positive QFT results. There was an unusually high rate of MA response on QFT testing in both groups. CONCLUSION: Phoenix Firefighters have a higher than expected TBST and QFT results, which cannot be explained by the increased MA rate. The decreased level of QFT positivity in comparison to TBST results may indicate a considerable false positive TBST rate. The QFT offers many advantages as a surveillance method over TBST in exposed worker populations

Human Glial-Restricted Progenitor Transplantation into Cervical Spinal Cord of the SOD1G93A Mouse Model of ALS

Cellular abnormalities are not limited to motor neurons in amyotrophic lateral sclerosis (ALS). There are numerous observations of astrocyte dysfunction in both humans with ALS and in SOD1G93A rodents, a widely studied ALS model. The present study therapeutically targeted astrocyte replacement in this model via transplantation of human Glial-Restricted Progenitors (hGRPs), lineage-restricted progenitors derived from human fetal neural tissue. Our previous findings demonstrated that transplantation of rodent-derived GRPs into cervical spinal cord ventral gray matter (in order to target therapy to diaphragmatic function) resulted in therapeutic efficacy in the SOD1G93A rat. Those findings demonstrated the feasibility and efficacy of transplantation-based astrocyte replacement for ALS, and also show that targeted multi-segmental cell delivery to cervical spinal cord is a promising therapeutic strategy, particularly because of its relevance to addressing respiratory compromise associated with ALS. The present study investigated the safety and in vivo survival, distribution, differentiation, and potential efficacy of hGRPs in the SOD1G93A mouse. hGRP transplants robustly survived and migrated in both gray and white matter and differentiated into astrocytes in SOD1G93A mice spinal cord, despite ongoing disease progression. However, cervical spinal cord transplants did not result in motor neuron protection or any therapeutic benefits on functional outcome measures. This study provides an in vivo characterization of this glial progenitor cell and provides a foundation for understanding their capacity for survival, integration within host tissues, differentiation into glial subtypes, migration, and lack of toxicity or tumor formation
