Attraction To Group, Group Cohesiveness, and Individual Outcome

A central hypothesis in the group psychotherapy literature is that group cohesiveness leads to better outcome in groups (Yalom, 1975). Group cohesiveness is thought to be both a prerequisite to and a natural consequence of successful therapeutic group process. Yalom et al. (1967) developed an 11-item questionnaire to operationalize cohesiveness. The questionnaire assessed attraction to group, to members, and to leaders, feelings of participation and inclusion, and attitudes regarding group length and frequency. They found that individuals’
Bmi-1 overexpression as an efficient prognostic marker in patients with nonsmall cell lung cancer

Background: The prognostic effect of B-cell-specific Moloney leukemia virus insertion site 1 (Bmi-1) in patients with nonsmall cell lung cancer (NSCLC) remains controversial. We thus performed a meta-analysis to reveal the correlation between Bmi-1 with clinical features and overall survival (OS) in NSCLC. Methods: Relevant studies were searched through PubMed, Embase, and Web of Science. Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) as well as odds ratios (ORs) and 95% CIs were calculated by using STATA version 12.0. Results: Fourteen studies consisting of 1323 patients were included for quantitative analysis. The results showed that Bmi-1 was significantly associated with tumor size (n = 7, OR = 1.79, 95% CI = 1.19–2.71, P = .005, fixed effect), poor differentiation (OR = 1.61, 95% CI = 1.11–2.33, P = .011, fixed effect), and distant metastasis (n = 4, OR = 4.69, 95% CI = 1.52–14.41, P = .007, fixed effect). In addition, high Bmi-1 expression also predicted poor OS (HR = 1.62, 95% CI = 1.14–2.3, P < .001). There was no significant publication bias for any of the analyses. Conclusion: In conclusion, Bmi-1 overexpression was correlated with tumor size, poor differentiation, distant metastasis, and worse OS in NSCLC. Therefore, Bmi-1 could be recommended as an efficient prognostic marker for NSCLC.
Chilean Strawberry Consumption Protects against LPS-Induced Liver Injury by Anti-Inflammatory and Antioxidant Capability in Sprague-Dawley Rats

The Chilean strawberry fruit has high content of antioxidants and polyphenols. Previous studies evidenced antioxidant properties by in vitro methods. However, the antioxidant effect and its impact as functional food on animal health have not been evaluated. In this study, rats were fed with a Chilean strawberry aqueous extract (4 g/kg of animal per day) and then subjected to LPS-induced liver injury (5 mg/kg). Transaminases and histological studies revealed a reduction in liver injury in rats fed with strawberry aqueous extract compared with the control group. Additionally, white strawberry supplementation significantly reduced the serum levels and gene expression of TNF-α, IL-6, and IL-1β cytokines compared with nonsupplemented rats. The level of F2-isoprostanes and GSH/GSSG indicated a reduction in liver oxidative stress by the consumption of strawberry aqueous extract. Altogether, the evidence suggests that dietary supplementation of rats with a Chilean white strawberry aqueous extract favours the normalization of oxidative and inflammatory responses after a liver injury induced by LPS.
Formation of a Partially Screened Inner Acceleration Region in Radio Pulsars: Drifting Subpulses and Thermal X-Ray Emission from Polar Cap Surface

The subpulse drifting phenomenon in pulsar radio emission is considered within the partially screened inner gap model, in which the sub-Goldreich-Julian thermionic flow of iron ions or electrons coexists with the spark-associated electron-positron plasma flow. We derive a simple formula that relates the thermal X-ray luminosity LX from the spark-heated polar cap and the × subpulse periodicity 3 (polar cap carousel time). For PSRs B0943+10 and B1133+16, the only two pulsars for which both 3 and LX are known observationally, this formula holds well. For a few other pulsars, for which only one quantity is measured observationally, we predict the value of the other quantity and propose relevant observations that can confirm or discard the model. Then we further study the detailed physical conditions that allow such partially screened inner gap to form. By means of the condition Tc/Ts > 1 (where Tc is the critical temperature above which the surface delivers a thermal flow to adequately supply the corotation charge density, and Ts is the actual surface temperature), it is found that a partially screened gap (PSG) can be formed given that the near surface magnetic fields are very strong and curved. We consider both curvature radiation (CR) and resonant inverse Compton scattering (ICS) to produce seed photons for pair production, and find that the former is the main agency to produce gamma rays to discharge the PSG.
Do Cascades Recur?

Cascades of information-sharing are a primary mechanism by which content reaches its audience on social media, and an active line of research has studied how such cascades, which form as content is reshared from person to person, develop and subside. In this paper, we perform a large-scale analysis of cascades on Facebook over significantly longer time scales, and find that a more complex picture emerges, in which many large cascades recur, exhibiting multiple bursts of popularity with periods of quiescence in between. We characterize recurrence by measuring the time elapsed between bursts, their overlap and proximity in the social network, and the diversity in the demographics of individuals participating in each peak. We discover that content virality, as revealed by its initial popularity, is a main driver of recurrence, with the availability of multiple copies of that content helping to spark new bursts. Still, beyond a certain popularity of content, the rate of recurrence drops as cascades start exhausting the population of interested individuals. We reproduce these observed patterns in a simple model of content recurrence simulated on a real social network. Using only characteristics of a cascade's initial burst, we demonstrate strong performance in predicting whether it will recur in the future.
Conceptualizing and Engaging in Organizational Change as an Embodied Experience within a Practical Reflexivity Community of Practice: Gender Performance at the U.S. Coast Guard Academy

In this article, we outline our organizational change initiative, our “small experiment,” and our attempt to understand how organizational change is actually accomplished. It is our desire to first change our selves and how we perform gender and through this local initiative, to eventually change how our organization as a whole performs gender. In our effort to accomplish this goal, we began by attempting to understand the issue, our experience, and the performance of gender within our organization. Based upon these understandings and because of this understanding, we will identify initiatives that change our organization's performance of gender. Finally, in an attempt to understand the micro- processes of change, of how organizational change is accomplished - “its dynamic, unfolding, emergent qualities (in short its potential) (Tsoukas & Chia, 2002, 568),” we will document and attempt to understand our experience of change from within.

Clinical Analysis of Incidentally Discovered Unruptured Aneurysms

Background and Purpose We analyzed the risk factors for rupture of an intracranial aneurysm based on a retrospective angiographic study of ruptured and unruptured aneurysms. Methods The 44 cases of asymptomatic aneurysms were selected from 1612 patients whose lesions had been discovered fortuitously by angiography (2.7%) during the period from 1980 to 1989. All these patients were free from any sign of intracranial aneurysm. The variations in age, sex, and location of the aneurysms were analyzed compared with 638 ruptured aneurysms that had been treated in our institute during the same period. The size, shape, and arterial geometry of the unruptured aneurysms were examined angiographically. Results Unruptured aneurysm was discovered fortuitously in 44 (2.7%) of 1612 patients, with greater incidence in women aged older than 60 years. Unruptured aneurysms were less likely to occur in the anterior communicating artery (12.8%) and the middle cerebral artery (6.4%). However, they were frequently found in the internal carotid artery, with an incidence of 10.6% in the cavernous portion of the internal carotid artery, 19.1% in the internal cartoid-ophthalmic artery, 19.1% in the internal carotid-posterior communicating artery, and 12.8% in the internal carotid-anterior choroidal artery. Seven of the nine internal carotid-posterior communicating artery aneurysms showed a hypoplastic or aplastic posterior communicating artery. The mean diameter of the unruptured aneurysms was 4.8 mm, and 80% were smaller than 6 mm. Conclusions Intracranial aneurysms are formed not only at the bifurcation of an artery but also at its branching and bending points. However, an aneurysm located at the bifurcation, such as the anterior communicating artery and the middle cerebral artery, bleeds easily in contrast with lateral aneurysms such as those found at the branching and bending points on the internal carotid artery.
Comparison of two durations of triple-drug therapy in patients with uncomplicated brucellosis: A randomized controlled trial

Abstract Background: Brucellosis remains the most common zoonotic disease throughout the world and especially in Iran. Several clinical trials have tested different therapeutic regimens for brucellosis, but few have assessed the optimal duration of treatment. Methods: We performed a randomized controlled trial to compare a triple-drug regimen of doxycycline plus rifampicin for 6 weeks and streptomycin for the first 7 days with doxycycline plus rifampicin for 8 weeks and streptomycin for 7 days in patients with uncomplicated brucellosis in Arak, Iran. The primary outcome measure for the treatment groups was the relapse rate measured at 1, 3, 6, 12, and 24 months after cessation of therapy. Results: Eligible patients were randomized to one of the 2 groups with 72 per arm. We found no significant difference in the relapse rate for the 8-week treatment group compared to the 6-week group (9.7% vs 13.9%). There were no significant differences between the 6-week and 8-week groups regarding the relapse rate, period between clinical presentation and beginning of treatment, and time of relapse. Symptom resolution was achieved in all cases at a median 9.5 days and no cases experienced continuing symptoms after treatment. Conclusions: Our trial found no significant difference between 6-week and 8-week regimens of doxycycline and rifampicin plus streptomycin for the first 7 days. Further comparative studies with a large sample size should be implemented to achieve a consistent therapeutic regimen for uncomplicated brucellosis, to help identify those who may benefit from longer treatment, and to minimize adverse effects and unnecessary continuation of treatment.
Using Parcels to Convert Path Analysis Models Into Latent Variable Models

The biasing effects of measurement error in path analysis models can be overcome by the use of latent variable models. In cases where path analysis is used in practice, it is often possible to use parcels as indicators of a latent variable. The purpose of the current study was to compare latent variable models in which parcels were used as indicators of the latent variables, path analysis models of the aggregated variables, and models in which reliability estimates were used to correct for measurement error in path analysis models. Results showed that point estimates of path coefficients were smallest for the path analysis models and largest for the latent variable models. It is concluded that, whenever possible, it is better to use a latent variable model in which parcels are used as indicators than a path analysis model using total scale scores.
The Immediate and Long-Term Effects of Family Income on Child and Adolescent Bullying

Abstract Utilizing data from the National Longitudinal Survey of Youth Mother and Child Samples, I investigate the relationship between bullying behavior and family income. I test the hypothesis that the relationship between bullying and socioeconomic status is curvilinear, with children from low and high-income families engaging in higher levels of bullying than those from middle- income families. Further, within the proposed U-shaped relationship between bullying and family income, I examine whether children from low-income families bully more than those from high income families. As expected, there is a curvilinear relationship between bullying and income. While low-income youth are at greatest risk for engaging in bullying, those youth at the upper end of the income gradient also have a higher propensity for participating in bullying behavior, compared to their more moderate-income counterparts. Although levels of bullying behavior decrease over time at both the lower and upper ends of the income gradient, strong curvilinear associations between bullying and family income exist both in cross-sectional and longitudinal analyses. Further, child's age, school standing, and the amount of emotional support offered to the child are important factors in the initiation of bullying and in whether the behavior persists over time.
Screening for cervical cancer: should we test for infection with high-risk HPV?

At present more than 70 types of human papillomavirus (HPV) have been recognized, of which 35 represent mucosal types. These mucosal HPV types can be subdivided into high-risk or oncogenic types and low-risk or non-oncogenic types. Recent studies have shown that high-risk HPV is present in more
Prevalence and Predictive Factors of Fecal Incontinence

Background/Aims Most previous epidemiologic studies about fecal incontinence were performed in specific populations in Korea. We aimed to estimate the prevalence and predictive factors of fecal incontinence in adult Korean population, both men and women aged 20 years and over. Methods Subjects who had undergone medical check-up for health screening were enrolled. They completed the structured questionnaires, including demographics, gastrointestinal symptoms, medical and social histories, and also about their bowel habits. Logistic regression models were constructed to identify the predictive factors for having fecal incontinence. Results Among the total of 1,149 subjects (mean age, 44.8 ± 10.2 years; 648 males), the overall prevalence of fecal incontinence was 6.4%, while the older group (> 50 years old) showed the higher prevalence than the younger group (≤ 50 years old) (10.4% vs 4.9%, P = 0.001) without gender difference. Most patients had mild fecal incontinence in 78.4%. By multivariate analysis, old ages (Odd ratio [OR], 3.1; 95% confidence interval [CI], 1.9-5.2; P < 0.001), watery stool (OR, 2.8; 95% CI, 1.5-4.9; P = 0.001) and functional diarrhea (OR, 2.7; 95% CI, 1.4-5.4; P = 0.004) were found to be independent predictors for fecal incontinence. Conclusions The prevalence of fecal incontinence in Korean adults was 6.4%, and it was significantly more prevalent in older people without any gender difference. Aging and diarrhea were independent predictive factors of fecal incontinence. Therefore, proper control of the bowel pattern would lead to the prevention of fecal incontinence.
Training the integrate-and-fire model with the informax principle: I

In terms of the informax principle, and the input-output relationship of the integrate-and-fire (IF) model, IF neuron learning rules are developed. For supervised learning and with uniform weight of synapses (the theoretically tractable case), we show that the derived learning rule is stable and the stable state is unique. For unsupervised learning, within physiologically reasonable parameter regions, both long-term potentiation (LTP) and long-term depression (LTD) could happen when the inhibitory input is weak, but LTD cannot be observed when inhibitory input is strong enough. When both LTP and LTD occur, LTD is observable when the output of the postsynaptic neuron is faster than pre-synaptic inputs, otherwise LTP is observable, as observed in recent experiments. Learning rules of general cases are also studied and numerical examples show that the derived learning rule tends to equalize the contribution of different inputs to the output firing rates.
Comparison of Four SVM Classifiers Used with Depth Sensors to Recognize Arabic Sign Language Words

The objective of this research was to recognize the hand gestures of Arabic Sign Language (ArSL) words using two depth sensors. The researchers developed a model to examine 143 signs gestured by 10 users for 5 ArSL words (the dataset). The sensors captured depth images of the upper human body, from which 235 angles (features) were extracted for each joint and between each pair of bones. The dataset was divided into a training set (109 observations) and a testing set (34 observations). The support vector machine (SVM) classifier was set using different parameters on the gestured words’ dataset to produce four SVM models, with linear kernel (SVMLD and SVMLT) and radial kernel (SVMRD and SVMRT) functions. The overall identification accuracy for the corresponding words in the training set for the SVMLD, SVMLT, SVMRD, and SVMRT models was 88.92%, 88.92%, 90.88%, and 90.884%, respectively. The accuracy from the testing set for SVMLD, SVMLT, SVMRD, and SVMRT was 97.059%, 97.059%, 94.118%, and 97.059%, respectively. Therefore, since the two kernels in the models were close in performance, it is far more efficient to use the less complex model (linear kernel) set with a default parameter.
Leadership and management training as a catalyst to health system strengthening in low-income settings: Evidence from implementation of the Zambia Management and Leadership course for district health managers in Zambia

Background Research has shown that the modes of leadership and management may influence health outcomes. However, majority of health leaders and managers in many low-income countries are promoted on account of clinical expertise. It has been recognised that these new managers are often ill-prepared for managing complex health systems. In response to this challenge, the Zambian Ministry of Health (MoH) has developed the Governance and Management Capacity Building (GMCB) Strategic Plan (2012–2016), whose overarching goal is to improve health sector governance and create an environment that is result-oriented, accountable and transparent. This led to the introduction of a new in-service leadership and management course, which has come to be known as the Zambia Management and Leadership Academy (ZMLA). This paper presents the results of an impact evaluation of the ZMLA programme conducted in 2014. Methods This was a cross-sectional mixed method study. The study targeted health workers, stakeholders and course implementers. ZMLA trainees were targeted to gain perspectives on the extent to which the programme affected levels of self-confidence resulting from knowledge gained. Perspectives were sought from both ZMLA and non ZMLA trainees to measure changes in the work environment. Stakeholder perspectives were collected from trainers and key informants involved in providing ZMLA training. Results On average, knowledge levels increased by 38% after each workshop. A comparison of the average self-rated scores from 444 management and leadership survey responses before ZMLA and after ZMLA training showed a significant increase in the proportion of participants that felt adequately trained to undertake management and leadership, from 63% (before) to 99% (after) in phase 1 and 43% (before) to 98% (after) in the phase II cohort. The calculated before and after percentage change for work environment themes ranged from 5.8% to 13.4%. Majority of respondents perceived improvements in the workplace environment, especially in handling human resource management matters. The smallest improvement was noted in ethics and accountability. Qualitative interviews showed improvements in the meeting culture and a greater appreciation for the importance of meetings. Shared vision, teamwork and coordination seemed to have improved more in work places where the overall manager had received ZMLA training. Conclusion Leadership and management training will be a key ingredient in health system strengthening in low-income settings. The ZMLA model was found to be acceptable and effective in improving knowledge and skills for health system managers with minimal disruption to health services.
Core Self-Evaluations, Career Decision Self-Efficacy, and Vocational Identity Among Greek Adolescents

This study explored the mediating role of career decision self-efficacy between core self-evaluations (CSE), a newly established construct within the personality domain, and adolescents’ vocational identity. Using a sample of 200 Greek high school students, it was found that for female adolescents CSE influenced vocational identity both directly and indirectly (via career decision self-efficacy). For male students, CSE had only an indirect effect on vocational identity through career decision self-efficacy. The findings are discussed with reference to social cognitive career theory (SCCT) framework. Implications for research and adolescents’ career counseling are also discussed.
Deltoid muscular flap transfer for the treatment of irreparable rotator cuff tears

The purpose of this study was to evaluate the outcome of deltoid muscle flap transfer for the treatment of irreparable rotator cuff tears. In a retrospective study 20 consecutive patients were evaluated. The index procedure took place between 2000 and 2003. Fifteen patients were male, mean age was 62 years. Inclusion criterion was a rotator cuff defect Bateman grade IV. Exclusion criteria were smaller defects, shoulder instability and fractures of the injured shoulder. An open reconstruction with acromioplasty and a pedicled delta flap was performed. Follow up period was mean 42 months. Follow-up included clinical examination, Magnetic Resonance Imaging (MRI) and the Constant and Simple (CS) shoulder tests. According to the Constant shoulder test the results were good in 13 patients, fair in 5 and unsatisfactory in 2. The pre-operative Constant Score improved from mean 25.7 points (±5.3) to 72.3 (±7.8) at follow-up. The mean values for the subcategories of CS increased significantly from 3.9 to 14.4 points for pain and from 4.2 to 15.9 points for activities daily routine (p<0.05). The change in range of motion and strength were not significant (p>0.05). Results of the Simple Shoulder Test showed a significant increase of the mean values from pre-operative 4.3 to 14.7 points post-operatively. MRI showed a subacromial covering of the defect in all cases, all flaps where intact on MRI but always the flap showed marked fatty degeneration. In conclusion, the delta flap is a simple method for the repair of large defects of the rotator cuff leading to satisfying medium results.
