Co-worker Relations: A Branch Off of the Social Penetration Theory

This proposal aims to elaborate on the social penetration theory, specifically, in relation to co-worker interactions and how they coincide. In order to do so, ethnographical experiences and a multitude of research articles were analyzed. There are, however, no current studies that exemplify similarities between the pattern of the Social Penetration Theory(SPT) as applied to a workplace setting. By analyzing past research, delving into the Social Penetration Theory, and proposing different ways to approach research, I believe that this demonstration can help understand and explain the fast pace in which co-workers divulge personal information to one another. This pitch of this research has brought to light the fact that more could be done to understand why co-workers have their own category of relationship. They may not be considered “close,” yet most co-worker relationships penetrate deeper cores of one’s personality structure. Though it may seem mundane, every adult, at some point in their lives, will have to hold a job and interact with co-workers. The hope, is that this proposal will open the avenue to make people aware of the information they share by considering both qualitative and quantitave data

The Influence of Health Framing on Weight Stigma and Health Knowledge

With increasing rates of obesity and obesity-related health problems, recent years have seen a great deal of effort exerted to improve physical health by reducing obesity. While information about health is frequently communicated through news media, research has shown that news articles do not increase knowledge of physical health behaviors and instead increase weight stigma, which predicts decreased physical and mental health. Given that this method of presenting health information is ineffective and harmful, it is important to examine alternative ways to frame information on physical health behaviors. This study examined differential effects of three article types, Health Improvement, Weight Loss, or Control on health behavior knowledge, anti-fat attitudes, and health locus of control. Protestant work ethic, ethnicity, and BMI were also explored as moderators in the relationship between type of article and change in anti-fat attitudes. Participants were recruited from the subject pool at a university in Southern California and by posts on the social media site Reddit.com. The final sample size of 124 was 62.1% female, with ages ranging from 18 to 65 (M = 26.58, SD = 9.82) and a mean BMI of 25.38 (SD = 6.59). The hypotheses were not supported, with no dependent variables changing significantly over time and type of article not showing a significant effect on change in the dependent variables, all p \u3e .05. While the covariates did predict anti-fat attitudes overall (all p \u3c .01), no interactions between the covariates and the main effects were significant. These results are not in line with previous research, which is likely due to factors such as small sample size, measurement differences, and study design limitations. To our knowledge, this is the first study to examine the effects of news articles on increasing health behavior knowledge and health locus of control in addition to decreasing weight stigma. Future studies would benefit from increased sample size. In addition, it would be helpful to alter published news articles to reduce the differences between articles and include specific information on health knowledge that was examined by the measures; this would prevent the inclusion of additional confounds

Weight Stigma as a Mediator among BMI, Childhood Overweight, Body Image and Depression

Higher body mass index (BMI), childhood overweight, and weight stigmatization are correlated with depression and body dissatisfaction. Given that overweight/obese individuals are likely to experience significant weight stigma, the goal of the current study was to examine the effects of current weight and childhood overweight on depression and body dissatisfaction, and to examine weight stigmatization as a mediator in these relationships. Participants were 380 undergraduate students from the University of South Florida (84.5% female) with a mean age of 21.18 (SD = 4.32) and a mean BMI of 23.86 (SD = 5.03). Of these students, 53.4% were White, 24.7% were Hispanic, 10.0% were Black, 7.9% were Asian, and 3.9% reported Other; 31% reported having been overweight as children. A measurement model and three structural models were examined using EQS Version 6.2. The measurement model was found to have very good fit: χ2 (1) = 0.000, p \u3e .98; CFI = 1.0; SRMR = .00; RMSEA = .000, 90% CI [0.00, 0.00]; all correlation residuals \u3c |.10|. The final full model was the best-fitting structural model, with very good fit: χ2 (8) = 9.607, p \u3e.29; CFI = .999; SRMR = .013; RMSEA = .023, 90% CI [0.000, 0.067]; all residuals \u3c |.10|. This is the first study to examine the relationships among weight stigma experience, depression, and body image dissatisfaction. Results indicated that weight stigma explained some of the variance in the relationships between current BMI and body dissatisfaction and current BMI and depressive symptoms. Weight stigma was also found to explain some of the variance in the relationship between childhood overweight and depressive symptoms. In addition, after controlling for childhood overweight and body image dissatisfaction, higher current BMI predicted lower levels of depressive symptoms. This is the first study to examine weight stigma as a mediator of the effects of BMI and childhood overweight on depression and body image dissatisfaction. The current study highlights the need to address weight stigmatization among overweight/obese individuals and to promote public education on the short- and long-term effects of weight stigma. Future researchers should examine the effect of other variables on the development of depressive symptoms in overweight and obese individuals, as well as potential protective factors

Contrary to previous claims, it is shown that the expectation values of the quantum stress tensor for a massless scalar field propagating on a two-dimensional extreme Reissner-Nordstrom black hole are indeed regular on the horizon.Comment: 5 pages, revtex, 1 figur

Statistical analysis of Ni nanowires breaking processes: a numerical simulation study

A statistical analysis of the breaking behavior of Ni nanowires is presented. Using molecular dynamic simulations, we have determined the time evolution of both the nanowire atomic structure and its minimum cross section (Sm(t)). Accumulating thousands of independent breaking events, Sm histograms are built and used to study the influence of the temperature, the crystalline stretching direction and the initial nanowire size. The proportion of monomers, dimers and more complex structures at the latest stages of the breaking process are calculated, finding important differences among results obtained for different nanowire orientations and sizes. Three main cases have been observed. (A) [111] stretching direction and large nanowire sizes: the wire evolves from more complex structures to monomers and dimers prior its rupture; well ordered structures is presented during the breaking process. (B) Large nanowires stretched along the [100] and [110] directions: the system mainly breaks from complex structures (low probability of finding monomers and dimers), having disordered regions during their breakage; at room temperature, a huge histogram peak around Sm=5 appears, showing the presence of long staggered pentagonal Ni wires with ...-5-1-5-... structure. (C) Initial wire size is small: strong size effects independently on the temperature and stretching direction. Finally, the local structure around monomers and dimmers do not depend on the stretching direction. These configurations differ from those usually chosen in static studies of conductance.Comment: 18 pages, 13 figure

A new study of an old sink of sulfur in hot molecular cores: the sulfur residue

Sulfur appears to be depleted by an order of magnitude or more from its elemental abundance in star-forming regions. In the last few years, numerous observations and experiments have been performed in order to to understand the reasons behind this depletion without providing a satisfactory explanation of the sulfur chemistry towards high-mass star-forming cores. Several sulfur-bearing molecules have been observed in these regions, and yet none are abundant enough to make up the gas-phase deficit. Where, then, does this hidden sulfur reside? This paper represents a step forward in our understanding of the interactions among the various S-bearing species. We have incorporated recent experimental and theoretical data into a chemical model of a hot molecular core in order to see whether they give any indication of the identity of the sulfur sink in these dense regions. Despite our model producing reasonable agreement with both solid-phase and gas-phase abundances of many sulfur-bearing species, we find that the sulfur residue detected in recent experiments takes up only ~6 per cent of the available sulfur in our simulations, rather than dominating the sulfur budget.Comment: 13 pages, 6 colourful figures, accepted by MNRA
