Exploring the Phenomenon of Presence in an Online Educational Environment Through the Lived Experiences of Graduate Nursing Faculty

In this dissertation, the phenomenon of presence in an online educational environment is explored through the lived experiences of graduate nursing faculty who teach online. Greater understanding of the phenomenon of presence in online educational environments may lead to better learner-instructor relationships, higher levels of inquiry and critical thinking on the part of faculty and students, and ultimately better student outcomes. Utilizing principles of Hermeneutic Phenomenology and deductive inquiry, and based on the learner-centric Being There for the Online Learner Model, the author conducted in-depth interviews with a purposive sample of 13 graduate nursing faculty members who teach online at a major university in the northeast United States. The author also reviewed supporting documents pertaining to institutional structure, faculty development, the institution\u27s learning management system, and online faculty job descriptions. Interview data were analyzed thematically, using the mixed-methods software Dedoose. Results of the study revealed four ways in which graduate nursing faculty experience the sense of presence (i.e., The Modes of Presence derived from the Being There for the Online Learner Model): Realism, Involvement, Immersion, and the Willing Suspension of Disbelief. Two broad themes, Being there and Being Together were also identified. Being There is the sensation that occurs when graduate nursing faculty feel or perceive they are physically in another location when teaching online. Being Together is the sensation that graduate nursing faculty are physically in the same space with others (i.e., their students), when they are actually separated by distance. In both cases, this is for varying lengths of time, and with varying frequency. The study identified three main conclusions: not all participants experience the sense of presence in the same way; Being There may also include the sensation of Coming Here ; and, The Illusion of Nonmediation, as described in the Model, should be considered as a fifth Mode of Presence. Based upon these conclusions, I present implications for nursing education science and provide recommendations for creating the sense of presence in online educational environments

Cell-Cell Interactions and the Regulation of Testis Function

Regulatory interactions have been shown to occur between all the testicular cell types considered. The paracrine factors mediating these interactions generally influence either cellular growth or differentiation. The regulation of cellular growth is essential in the developing testis and is required for the maintenance of spermatogenesis in the adult testis. The rapid rate of germinal cell proliferation and the continuous but slowed growth of the peritubular cells and Leydig cells requires the presence of specific growth factors in the adult. Therefore, cell-cell interactions have evolved that involve growth factors such as IGF, TGF-alpha, TGF-beta and NGF. Other growth factors such as FGF or less characterized components like the seminiferous growth factor (SGF) also may be involved in the paracrine regulation of testis cell growth. An alternate cellular parameter to cell growth to consider is the regulation of cellular function and differentiation. A number of endocrine agents and locally produced paracrine factors have been shown to control and maintain testis cell function and differentiation. Cell-cell interactions mediated by factors such as androgens, POMC peptides, and PModS are all primarily directed at the regulation of cellular differentiation. Therefore, the agents which mediate cell-cell interactions in the testis can generally be categorized into factors that regulate cell growth or those which influence cellular differentiation. The specific cell-cell interactions identified will likely be the first of a large number of cellular interactions yet to be investigated. Although a number of potentially important cell-cell interactions have been identified, future research will require the elucidation of the in vivo physiological significance of these interactions. The existence of different cell types and potential cell-cell interactions in a tissue implies that the actions of an endocrine agent on a tissue will not simply involve a single hormone and single cell. The endocrine regulation of testis function will have effects on cell-cell interactions and be affected by local cell-cell interactions. The ability of LH to influence Leydig cell androgen production promotes a cascade of interactions mediated through several cell types to maintain the process of spermatogenesis. FSH actions on Sertoli cells also promote cell-cell interactions that influence germinal cell development, peritubular myoid cell differentiation and Leydig cell function. Therefore, elucidation of the endocrine regulation of testis function requires an understanding of the local cell-cell interactions in the testis

The association between Colombian medical students' healthy personal habits and a positive attitude toward preventive counseling: cross-sectional analyses

<p>Abstract</p> <p>Background</p> <p>Physician-delivered preventive counseling is important for the prevention and management of chronic diseases. Data from the U.S. indicates that medical students with healthy personal habits have a better attitude towards preventive counseling. However, this association and its correlates have not been addressed in rapidly urbanized settings where chronic disease prevention strategies constitute a top public health priority. This study examines the association between personal health practices and attitudes toward preventive counseling among first and fifth-year students from 8 medical schools in Bogotá, Colombia.</p> <p>Methods</p> <p>During 2006, a total of 661 first- and fifth-year medical students completed a culturally adapted Spanish version of the "Healthy Doctor = Healthy Patient" survey (response rate = 78%). Logistic regression analyses were used to assess the association between overall personal practices on physical activity, nutrition, weight control, smoking, alcohol use (main exposure variable) and student attitudes toward preventive counseling on these issues (main outcome variable), stratified by year of training and adjusting by gender and medical training-related factors (basic knowledge, perceived adequacy of training and perception of the school's promotion on each healthy habit).</p> <p>Results</p> <p>The median age and percentage of females for the first- and fifth-year students were 21 years and 59.5% and 25 years and 65%, respectively. After controlling for gender and medical training-related factors, consumption of ≥ 5 daily servings of fruits and/or vegetables, not being a smoker or binge drinker were associated with a positive attitude toward counseling on nutrition (<it>OR </it>= 4.71; CI = 1.6–14.1; <it>p </it>= 0.006 smoking (<it>OR </it>= 2.62; CI = 1.1–5.9; <it>p </it>= 0.022), and alcohol consumption (<it>OR </it>= 2.61; CI = 1.3–5.4; <it>p </it>= 0.009), respectively.</p> <p>Conclusion</p> <p>As for U.S. physician and medical students, a positive association was found between the personal health habits of Colombian medical students and their corresponding attitudes toward preventive counseling, independent of gender and medial training-related factors. Our findings, the first relating to this association in medical students in developing regions, also suggest that within the medical school context, interventions focused on promoting healthy student lifestyles can potentially improve future physician's attitudes toward preventive counseling.</p

The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project – and avert – future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups – including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems – www.predicts.org.uk). We make site-level summary data available alongside this article. The full database will be publicly available in 2015
