The Health Guru: Masculinity and Fitness Coaching in the Blogosphere

Through a close study of blogs, where male fitness experts share their expertise, this article analyses how masculinity are framed within the Internet-mediated context of the fitness culture. This is done against the background of Connell's theory of masculinity, and recent critiques of the concept of hegemony. Through an in-depth analysis of three blogs, we get a complex and contradictory image of the different forms of masculinity portrayed in these blogs and in fitness culture at large. The texts and imagery on the blogs clearly exceeds the criteria/limits of traits and norms traditionally considered male or female. In doing so, the may contribute to an increased acceptance for, for example, gay identities and other submissive masculinities.
Star formation in the intragroup medium and other diagnostics of the evolutionary stages of compact groups of galaxies

Context. Compact groups of galaxies are entities that have high densities of galaxies and serve as laboratories to study galaxy interactions, intergalactic star formation and galaxy evolution. Aims. The main goal of this study is to search for young objects in the intragroup medium of seven compact groups of galaxies: HCG 2, 7, 22, 23, 92, 100 and NGC 92 as well as to evaluate the stage of interaction of each group. Methods. We used Fabry-Perot velocity fields and rotation curves together with GALEX NUV and FUV images and optical R-band and HI maps. Results. (i) HCG 7 and HCG 23 are in early stages of interaction; (ii) HCG 2 and HCG 22 are mildly interacting; and (iii) HCG 92, HCG 100 and NGC 92 are in late stages of evolution. We find that all three evolved groups contain populations of young blue objects in the intragroup medium, consistent with ages < 100 Myr, of which several are younger than < 10 Myr. We also report the discovery of a tidal dwarf galaxy candidate in the tail of NGC 92. These three groups, besides containing galaxies that have peculiar velocity fields, also show extended HI tails. Conclusions. Our results indicate that the advanced stage of evolution of a group, together with the presence of intragroup HI clouds, may lead to star formation in the intragroup medium. A table containing all intergalactic HII regions and tidal dwarf galaxies confirmed to date is appended.
Readiness for organisational change, resistance toward organisational change, behavioural support for organisational change and demographic characteristics : how they relate to a corporate social networking site change initiative.

Within the working environment, the attitudes and behaviours individuals display toward change are a fundamental part of whether change initiatives succeed or fail. In a growing world of computer-mediated communication, social networking sites are being incorporated into the corporate arena to better communication and functionality. Yet it still remains as a change initiative. This research report looked at whether readiness for organisational change, resistance toward organisational change and behavioural support for organisational change related to the perceptions and usage of a corporate SNS. Similarly demographic characteristics were also explored. Correlations, ANOVAs, a Chi squared, a Multiple Linear Regression and a Moderated Multiple Regression were conducted. The sample consisted of 118 participants of which, 65% were female, 59% were white, 49% were married and the 69% were under 49 years of age. The researcher found that readiness and behavioural support for organisational change related positively to the perceptions of the SNS whereas resistance to organisational change did not. Race significantly related to the perceptions of the SNS and SNS usage significantly related to the SNS uptake data categories. Conclusions and recommendations are also presented.
Concurrent Oncogene Mutation Profile in Chinese Patients With Stage Ib Lung Adenocarcinoma

AbstractMolecular characteristics in lung cancer are associated with carcinogenesis, response to targeted therapies, and prognosis. With concurrent oncogene mutations being reported more often, the adjustment of treatment based on the driver gene mutations would improve therapy. We proposed to investigate the distribution of concurrent oncogene mutations in stage Ib lung adenocarcinoma in a Chinese population and find out the correlation between survival outcome and the most frequently mutated genes in EGFR and KRAS in Chinese population. Simultaneously, we tried to validate the Sequenom method by real time fluoresce qualification reverse transcription polymerase chain reaction (RT-PCR) in oncogene detection.One hundred fifty-six patients who underwent complete surgical resection in our hospital between 1999 and 2007 were retrospectively investigated. Using time-of-flight mass spectrometry, 238 mutation hotspots in 19 oncogenes were examined.Genetic mutations occurred in 86 of 156 patients (55.13%). EGFR was most frequently gene contained driver mutations, with a rate of 44.23%, followed by KRAS (8.33%), PIK3CA (3.84%), KIT (3.20%), BRAF (2.56%), AKT (1.28%), MET (0.64%), NRAS (0.64%), HRAS (0.64%), and ERBB2 (0.64%). No mutations were found in the RET, PDGFRA, FGFR1, FGFR3, FLT3, ABL, CDK, or JAK2 oncogenes. Thirteen patients (8.3%) were detected in multiple gene mutations. Six patients had PIK3CA mutations in addition to mutations in EGFR and KRAS. EGFR mutations can coexist with mutations in NRAS, KIT, ERBB2, and BRAF. Only one case was found to have a KRAS mutation coexisting with the EGFR T790M mutation. Otherwise, mutations in EGFR and KRAS seem to be mutually exclusive. There is no survival benefit in favor of EGFR/KRAS mutation.Several concomitant driver gene mutations were observed in our study. None of EFGR/KRAS mutation was demonstrated as a prognostic factor. Polygenic mutation testing by time-of-flight mass spectrometry was validated by RT-PCR, which can be an alternative option to test for multiple mutations and can be widely applied to clinical practice and help to guide treatment.
PROCRASTINATION AND SELF-ESTEEM-A GENDER BASED STUDY

Procrastination is most often considered to be the irrational delay of behavior. Procrastination not only affects student grades, but also academic performance. It prevents students from reaching their objectives and goals; it inculcates a sense of discomfort, as things start accumulating. The present study aimed to assess how gender effect procrastination and self-esteem in university students. Sample encompassed 101 participants (51 female and 50 male) in the age range of 21-24years collected from University of Jammu. Lay’s General Procrastination scale for student population and Rosenberg’s Self-Esteem scale were used as tools. Results indicated no significant difference between male and female on procrastination however significant difference was found on self-esteem across gender. The mean scores indicated that female participants had increased level of self-esteem than male participants.
AN EXAMINATION OF COLLEGE STUDENTS' STATE ANXIETY TO TRAIT ANXIETY, PROBLEM SOLVING STATUS AND SPIRITUALITY

A total of 677 college students responded to the State-Trait Anxiety Inventory and Spirituality scale and Problem-Solving Inventory. This study investigates problem solving status, spirituality and levels of state anxiety among 677 college students. The findings of this quantitative study demonstrate that college students are rarely free of state anxiety. The results of the study showed that state anxiety is positive correlated with problems solving status, trait and spirituality. Moreover, by using multiple regression analyses, the predictor variables were able to account for 48% of the variance of State Anxiety. State anxiety could be predicted by four main predictors, “Trait anxiety”, “Purpose and meaning in life”, and “Problem Solving Confidence and Approach-Avoidance Style two subscales of the PSI”. The study’s limitations, implications for future research, and suggestions for diversifying career education are discussed.
Sedative use disorders in opiate-dependent patients: association with psychiatric and other substance use disorders.

Opiate-dependent patients (N = 231), classified by sedative disorder status, were characterized according to DSM-IIIR on substance use and psychiatric disorders. Twenty-one percent currently (CUR+) had sedative use disorder, 39% had a history (HX+) of sedative use disorder, and 40% had no history (HX-) of this disorder. Several group differences were found. The HX+ and CUR+ groups had more lifetime drug use disorders (means = 4.5 and 4.3 vs. 3.2 in the HX- group), including alcohol, cannabis, stimulants, cocaine, and hallucinogens. In contrast, other psychiatric disorders (e.g., anxiety and depression) were low in prevalence and did not differ across groups, with the exception of a higher prevalence of antisocial personality disorder in the HX+ and CUR+ groups (39.6% and 38.5% vs. 17.9% in HX- group). The results suggest that sedative use disorder is related more to a severe spectrum of multiple substance abuse than it is to self-medication of underlying mood or anxiety disorders.
α4 Integrin Is Expressed during Peripheral Nerve Regeneration and Enhances Neurite Outgrowth

We have shown previously that repair in the peripheral nervous system is associated with a reversion to an embryonic pattern of alternative splicing of the extracellular matrix molecule fibronectin. One of the consequent changes is a relative increase in the number of fibronectins expressing the binding site for α4 integrins. Here we show that α4 integrins are expressed on dorsal root ganglion neuron cell bodies and growth cones in the sciatic nerve during regeneration and that the interaction of α4 integrin with alternatively spliced isoforms of recombinant fibronectins containing the α4 binding site enhances neurite outgrowth in dorsal root ganglion neurons. The pheochromocytoma (PC12) neuronal cell line, which normally extends neurites poorly on fibronectin, does so efficiently when α4 is expressed in the cells. Experiments using chimeric integrins expressed in PC12 cells show that the α4 cytoplasmic domain is necessary and sufficient for this enhanced neurite outgrowth. In both dorsal root ganglion neurons and PC12 cells the α4 cytoplasmic domain is tightly linked to the intracellular adapter protein paxillin. These experiments suggest an important role for α4 integrin and paxillin in peripheral nerve regeneration and show how alternative splicing of fibronectin may provide a mechanism to enhance repair after injury.
Measuring Researcher-Production in Information Systems

While many studies have assessed IS researcher-production, most have focused on either ranking IS journals or assessing prolific researchers using a restricted time frame and a small “basket” of journals (i.e., those journals selected for sampling). We found no research that has assessed the IS specificity of journals (i.e., the suitability of journals for publishing IS research) nor any that evaluated IS researcher-production measures. Based on a coding of over 26,000 articles and more than 1,900 authors, this study attempts such an evaluation by (1) determining the rate of publication of IS researchers in 58 journals perceived by at least one IS institution as IS specific, (2) profiling prolific and typical IS researchers using descriptive statistics, (3) evaluating the convergent validity of various researcher-production measures, (4) assessing the reliability of these researcher-production measures by varying baskets of
Supporting E-Learning Within a Social Framework

E-learning has become a major delivery platform for higher education, continuing education and corporate training. The majority of e-learning research to date has taken place in academic environments using survey or qualitative research. This study used an experimental design (N = 99) to view three different models for supporting asynchronous e-learning in a corporate setting where learners are geographically distributed. The support interventions were rooted in andragogical principles of learning. Two treatment groups were provided socially engaging proactive models while the control group used a learner directed reactive authoritarian model. The purpose of this study was to see if different variables influenced trainee completion time and retention at six months of employment for new female branch administrators in a financial services company. The goal was to produce a predictive model for employee training completion and retention based upon type of e-learning support and other demographic and observed variables. Data analysis used multiple regression to determine if training completion time could be predicted. There was no significant relationship between any of the variables and time to completion. Logistic regression was used to model prediction of trainees most likely to stay on the job at six months. The only variable approaching significance from that analysis was gender of supervisor. Neither regression analysis resulted in a valid predictive model. This study used an available voluntary sample randomly assigned to treatment groups and tracked through training by dedicated support specialists trained in the different interventions. A larger sample size and different methods of treatment implementation should be studied with this population in the future. Keene, Barbara, 2008, UMSL, p.iv
Unconditional Convergence and Optimal Error Estimates of a Galerkin-Mixed FEM for Incompressible Miscible Flow in Porous Media

In this paper, we study the unconditional convergence and error estimates of a Galerkin-mixed FEM with the linearized semi-implicit Euler scheme for the equations of incompressible miscible flow in porous media. We prove that the optimal $L^2$ error estimates hold without any time-step (convergence) conditions, while all previous works require certain time-step restrictions. Our theoretical results provide a new understanding on commonly used linearized schemes. The proof is based on a splitting of the error into two parts: the error from the time discretization of the PDEs and the error from the finite element discretization of corresponding time-discrete PDEs. The approach used in this paper can be applied to more general nonlinear parabolic systems and many other linearized (semi)-implicit time discretizations.
Phrenic Nerve Graft For Bilateral Vocal Cord Paralysis

For bilateral vocal cord paralysis, the phrenic nerve graft procedure has been used in five patients. Data from four of these patients suggest that the technique may in some way improve the glottic airway without long‐term diaphragmatic paralysis. No patient to date has demonstrated visible inspiratory vocal cord abduction however. The mechanism of action, if any, is unclear at this time, and we have no electromyographic nor other physiologic data to confirm that true posterior cricoarytenoid muscle reinnervation has taken place.
Regional Difference in Stainability with Calcium-Sensitive Acetoxymethyl-Ester Probes in Mouse Brain Slices

Loading neurons with membrane permeable Ca2+ indicators is a core experimental procedure in functional multineuron Ca2+ imaging (fMCI), an optical technique for monitoring multiple neuronal activities. Although fMCI has been applied to several brain networks, including cerebral cortex, hippocampus, and cerebellum, no studies have systematically addressed the dye-loading efficiency in different brain regions. Here, we describe the stainability of Oregon Green 488 BAPTA-1AM in mouse acute brain slice preparations. The data are suggestive of the potential usability of fMCI in many brain regions, including olfactory bulb, thalamus, dentate gyrus, habenular nucleus, and pons.
PATUS: A Code Generation and Autotuning Framework for Parallel Iterative Stencil Computations on Modern Microarchitectures

Stencil calculations comprise an important class of kernels in many scientific computing applications ranging from simple PDE solvers to constituent kernels in multigrid methods as well as image processing applications. In such types of solvers, stencil kernels are often the dominant part of the computation, and an efficient parallel implementation of the kernel is therefore crucial in order to reduce the time to solution. However, in the current complex hardware micro architectures, meticulous architecture-specific tuning is required to elicit the machine's full compute power. We present a code generation and auto-tuning framework \textsc{Patus} for stencil computations targeted at multi- and many core processors, such as multicore CPUs and graphics processing units, which makes it possible to generate compute kernels from a specification of the stencil operation and a parallelization and optimization strategy, and leverages the auto tuning methodology to optimize strategy-dependent parameters for the given hardware architecture.
ROBUST D-STABILITY ANALYSIS OF UNCERTAIN POLYNOMIAL MATRICES VIA POLYNOMIAL-TYPE MULTIPLIERS

Abstract This paper addresses robust D -stability analysis problems of uncertain polynomial matrices. The underlying idea we follow is that a given polynomial matrix is D -stable if and only if there exist polynomial-type multipliers that render the resulting polynomial matrices to be strictly positive over a specific region on the complex plane. By applying the generalized S -procedure technique, we show that those positivity analysis problems can be reduced into feasibility tests of linear matrix inequalities (LMIs). Thus we can obtain varieties of LMI conditions for (robust) D -stability analysis of polynomial matrices according to the degree/structure of the multipliers to be employed. In particular, we show that existing LMI conditions for robust D -stability analysis can be viewed as particular cases of the proposed conditions, where the degree of the multipliers chosen to be the same as those of the polynomial matrices to be examined. It turns out that, by increasing the degree of the multipliers, we can readily obtain less conservative LMI conditions than the one found in the literature.
Development and Validation of an Instrument to Measure Students’ Motivation and Self‐Regulation in Science Learning

Students’ motivational beliefs and self‐regulatory practices have been identified as instrumental in influencing the engagement of students in the learning process. An important aim of science education is to empower students by nurturing the belief that they can succeed in science learning and to cultivate the adaptive learning strategies required to help to bring about that success. This article reports the development and validation of an instrument to measure salient factors related to the motivation and self‐regulation of students in lower secondary science classrooms. The development of the instrument involved identifying key determinants of students’ motivation and self‐regulation in science learning based on theoretical and research underpinnings. Once the instrument was developed, a pilot study involving 52 students from two Grade 8 science classes was undertaken. Quantitative data were collected from 1,360 students in 78 classes across Grades 8, 9, and 10, in addition to in‐depth qualitative information gathered from 10 experienced science teachers and 12 Grade 8 students. Analyses of the data suggest that the survey has strong construct validity when used with lower secondary students. This survey could be practically valuable as a tool for gathering information that may guide classroom teachers in refocusing their teaching practices and help to evaluate the effectiveness of intervention programmes.
Correlates of Job Stress in Policing: A Comparative Study of Women and Men Police

Policing is generally considered as a profession which is highly vulnerable to stress. Depending upon its nature, duration, and perceived intensity, this stress may result in various physiological, psychological or behavioural indicators of strains. Making use of the ‘Occupational Stress Inventory’ and this each of job-related and affective strain measures, the present study examined the correlations between job stress and strains in a sample of 500 police personnel. The results revealed significant correlations between job stress and the various job related and affective strains. The magnitude of the obtained correlations was greater in the case of the women police. Moreover, the sources of stress having significant correlations with the various strains were also more in the case of the women personnel.
Spatiotemporal Uptake Characteristics of [18]F-2-Fluoro-2-Deoxy-D-Glucose in a Rat Middle Cerebral Artery Occlusion Model

Background and Purpose— Alterations of cerebral glucose metabolism are well anticipated during cerebral ischemia. However, detailed spatiotemporal characteristics of disturbed cerebral glucose metabolism during acute ischemia remain largely elusive. This study aims to delineate spatiotemporal distributions of [18]F-2-fluoro-2-deoxy-D-glucose (FDG) uptake using positron emission tomography imaging, particularly at the peri-ischemic zone, and its correlation with tissue outcome. Methods— The intraluminal suture middle cerebral artery occlusion model was used to induce focal cerebral ischemia in rats (n=48). All animals underwent sequential MRI and FDG positron emission tomography imaging at different times (30–150 minutes) after middle cerebral artery occlusion. MR and positron emission tomography images were coregistered. FDG uptake in the peri-ischemic zone was assessed in relation to middle cerebral artery occlusion duration, cerebral blood flow, apparent diffusion coefficient, and 24-hour T2 lesions. Results— Elevated FDG uptake was consistently observed at the peri-ischemic zone surrounding the presumed ischemic core with low FDG uptake. Both the spatial volume and the uptake level of the hyper-uptake region were inversely correlated with the duration of middle cerebral artery occlusion. The hyper-uptake regions exhibited a mild reduction of cerebral blood flow (28.2±3.2%) and apparent diffusion coefficient (9.1±1.4%) when compared with that in the contralateral hemisphere. Colocalization analysis revealed that, with reperfusion, an average of 12.1±1.7% of the hyper-uptake volume was recruited into final infarction. Conclusions— Elevated FDG uptake at the peri-ischemic zone is consistently observed during acute cerebral ischemia. The region with elevated FDG uptake likely reflects viable tissues that can be salvaged with reperfusion. Therefore, acute FDG positron emission tomography imaging might hold promise in the management of patients with acute stroke.
Eye size in birds and the timing of song at dawn

Why do different species of birds start their dawn choruses at different times? We test the hypothesis that the times at which different species start singing at dawn are related to their visual capability at low light intensities. Birds with large eyes can achieve greater pupil diameters and hence, all other things being equal, greater visual sensitivity and resolution than birds with small eyes. We estimated the maximum pupil diameter of passerine birds by measuring the diameter of the exposed eye surface, and measured the times of the first songs at dawn of songbirds present in different bird communities, and the light intensities at these times. Using phylogenetic comparative analyses, we found that songbirds with large eyes started to sing at lower light intensities (and therefore earlier) than species with smaller eyes. These relationships were stronger when differences in body size were controlled for statistically, and were consistent between two phylogenies and when species were treated as independent data points. Our results therefore provide robust support for the hypothesis that visual capability at low light levels influences the times at which birds start to sing at dawn.
