Smart Phone Acceptance among Physicians: Application of Structural Equation Modelling in the Largest Iranian University

Background: The present study aimed to determine attitudes and effective factors in the acceptance of smart phones by physicians of the largest University of Medical Sciences in the south of Iran. Methods: This cross-sectional study was performed using Structural Equation Modelling (SEM) in 2014. Study participants included 200 physicians working in the hospitals of Shiraz University of Medical Sciences selected through two-stage stratified sampling, but 185 participants completed the study. The study data were collected using a researcher-made questionnaire completed through a 5-point Likert scale. The content validity of the questionnaire was confirmed by a panel of experts, its construct validity by confirmatory factor analysis, and its reliability by Cronbach’s alpha of 0.802. All data analyses were performed using SPSS (version 22) and LISREL (version 8.8). Results: Results showed that most physicians had a desirable attitude towards using smart phones. Besides, the results of SEM indicated a significant relationship between attitude and compatibility, observability, personal experience, voluntariness of use and perceived usefulness. Moreover, some important fitness indices revealed appropriate fitness of the study model (p=0.26, X2/df=1.35, RMR=0.070, GFI=0.77, AGFI=0.71, NNFI=0.93, CFI=0.94). Conclusion: The results revealed that compatibility, observability, personal experience, voluntariness of use and perceived usefulness were effective in the physicians’ attitude towards using smart phones. Thus, by preparation of the required infrastructures, policymakers in the field of health technology can enhance the utilization of smart phones in hospitals.
Comparison between Maladaptive Schemas, Marital Conflicts and Sexual Satisfaction in Nearly- Divorced, Divorced and Normal Individuals

The present research aims to compare the differences between maladaptive schemas, marital conflicts and sexual satisfaction in nearly-divorced, divorced and normal individuals of Masjed Soleyman County. The sample size includes 300 individuals, 100 divorced, 100 nearly-divorced and 100 normal individuals of Masjed Soleyman. Divorced and nearly-divorced individuals were chosen by the use of convenience sampling from the individuals visiting family justice center and normal individuals were chosen by the use of multistage cluster random sampling from one of the districts of Masjed Soleyman. Measuring tools include: Young Schema Questionnaire-Short Form (YSQ-SF), and Marital Conflicts Questionnaire (Revised Form) (RMCQ), and Linda Berg and Kersey Sexual Satisfaction Questionnaire (SSQ). The research methodology is causal-comparative. Results of MANOVA analysis showed that there is a significant difference between divorced, nearly divorced and normal individuals in terms of at least one of the dependent variables (maladaptive schemas, marital conflicts, and sexual satisfaction). Also Univariate analysis of variance showed that maladaptive schemas in terms of impaired autonomy and performance, impaired limits and other directness were not significant. At the end a few applicable research suggestions are provided.
FAMILIAL FACTORS, PERSONALITY TRAITS AND SELF-EFFICACY AS DETERMINANTS OF ENTREPRENEURIAL INTENTION AMONG VOCATIONAL BASED COLLEGE OF EDUCATION STUDENTS IN OYO STATE, NIGERIA

This study explored the influence of familial factors, personality traits and self-efficacy on entrepreneurial behavior among college of education students. A correlational research design was adopted for the study. The participants include 470 vocational based students in the two public Colleges of Education in Oyo state, Nigeria. Four research instruments were used to extract information from the participants. These include Entrepreneurial Intention Scale(r = 0.71), General Self-efficacy Scale (r =0.82), Big Five Inventory (0.83), and Bio-data Information. Two research questions were raised and answered in the study at 0.05 level of significance. Using Pearson Product Correlation Moment and multiple regression model, the results revealed that the independent variables examined jointly accounted for 74% of the total variance in entrepreneurial intention. The result also indicated that Parents occupation (t=2.45), extraversion (t=2.44), agreeableness (t=2.77), conscientiousness (t=3.30) neuroticism (t=-3.64), openness (t=23.66), and self-efficacy (t=3.99) linearly contributed to the prediction of entrepreneurial intention whereas family income did not. The outcomes of the study were discussed and it was suggested that counselling practitioners should take care of these variables while handling issues relating to entrepreneurial intention among students.
Joint Unitary Triangularization for Gaussian Multi-User MIMO Networks

The problem of transmitting a common message to multiple users over the Gaussian multiple-input multiple-output broadcast channel is considered, where each user is equipped with an arbitrary number of antennas. A closed-loop scenario is assumed, for which a practical capacity-approaching scheme is developed. By applying judiciously chosen unitary operations at the transmit and receive nodes, the channel matrices are triangularized so that the resulting matrices have equal diagonals, up to a possible multiplicative scalar factor. This, along with the utilization of successive interference cancellation, reduces the coding and decoding tasks to those of coding and decoding over the single-antenna additive white Gaussian noise channel. Over the resulting effective channel, any off-the-shelf code may be used. For the two-user case, it was recently shown that such joint unitary triangularization is always possible. In this paper, it is shown that for more than two users, it is necessary to carry out the unitary linear processing jointly over multiple channel uses, i.e., space-time processing is employed. It is further shown that exact triangularization, where all resulting diagonals are equal, is still not always possible, and appropriate conditions for the existence of such are established for certain cases. When exact triangularization is not possible, an asymptotic construction is proposed, that achieves the desired property of equal diagonals up to edge effects that can be made arbitrarily small, at the price of processing a sufficiently large number of channel uses together.
The Influence of Cognitive and Affective Based Job Satisfaction Measures on the Relationship Between Satisfaction and Organizational Citizenship Behavior

One of the most widely believed maxims of management is that a happy worker is a productive worker. However, most research on the nature of the relationship between job satisfaction and job performance has not yielded convincing evidence that such a relationship exists to the degree most managers believe. One reason for this might lie in the way in which job performance is measured. Numerous studies have been published that showed that using Organizational Citizenship Behavior to supplant more traditional measures of job performance has resulted in a more robust relationship between job satisfaction and job performance. Yet, recent work has suggested that the relationship between job satisfaction and citizenship may be more complex than originally reported. This study investigated whether the relationship between job satisfaction and citizenship could depend upon the nature of the job satisfaction measure used. Specifically, it was hypothesized that job satisfaction measures which reflect a cognitive basis would be more strongly related to OCB than measures of job satisfaction which reflect an affective basis. Results from data collected in two midwestern companies show support for the relative importance of cognition based satisfaction over affect based satisfaction. Implications for research on the causes of citizenship are discussed.
Risk of Gastrointestinal Bleeding with Dabigatran: A Head-to-Head Comparative Study with Rivaroxaban

Introduction: The risk of gastrointestinal (GI) bleeding of dabigatran and rivaroxaban is relatively unexplored. The aim of our study was to compare this risk in both drugs. Methods: We examined the medical records of patients on either dabigatran or rivaroxaban from October 2010 to April 2013 in two hospitals. Results: A total of 374 patients (147 rivaroxaban vs. 227 dabigatran) were identified. GI bleeding occurred in 5.3% in the dabigatran when compared to 4.8% in the rivaroxaban group (p = 0.8215). Multivariate analysis showed that the odds of GI bleeding while on dabigatran for ≤40 days when compared to ≥40 days was 8.3 (p < 0.0001). In the rivaroxaban group, patients who were on the drug for ≤40 days had a higher incidence of bleeding when compared to those >40 days (OR = 2.8, p = 0.023). Concomitant use of antiplatelets (single or dual) or non-steroidal anti-inflammatory drugs was not associated with increased bleeding in the dabigatran group; however, the use of dual antiplatelet agents with rivaroxaban was associated with an increased risk of GI bleeding (OR = 7.4, p = 0.0378). Prior GI bleeding had a higher risk of bleeding in the rivaroxaban group (OR = 15.5, p = 0.0002). Conclusion: Dabigatran was not associated with a higher incidence of GI bleeding. Both drugs had a higher bleeding risk in the first 40 days.
Patterns of brain electrical activity during facial signs of emotion in 10-month-old infants.

This study examined electroencephalogram (EEG) asymmetries during the presence of discrete facial signs of emotion. Thirty-five 10-month-old infants were tested in a standard stranger- and mother-approach paradigm that included a brief separation from their mother. Infant facial expression was videotaped, and brain electrical activity from left and right frontal and parietal regions was recorded. The videotapes were coded with two different discrete facial coding systems. Artifact-free periods of EEG were extracted that were coincident with the expression ofthe emotions of joy, anger, and sadness. The data revealed different patterns of EEG asymmetry depending on the type of facial expression and vocal expression of affect that was observed. Expressions of joy that involved facial actions of both zygomatic and orbicularis oculi were seen more often in response to mother approach, whereas smiles that did not involve the action of orbiculaxis oculi were seen more often in response to approach of the stranger. The former type of smile was associated with relative left frontal activation, whereas the latter type was associated with right frontal activation. Facial expressions of anger and sadness exhibited in the absence of crying were associated with left frontal activation, whereas these same facial expressions during crying were associated with right frontal activation. These data underscore the usefulness of EEG measures of hemispheric activation in differentiating among emotional states associated with differences in facial and vocalic expressivity. Recent evidence from the adult neuropsychological literature indicates that the cerebral hemispheres are differentially lateralized for the expression of certain positive and negative emotions (Bear & Fedio, 1977; Davidson, Schwartz, Saron, Bennett, & Goleman, 1979; Gainotti, 1969, 1972; Sackeim, Weiman, Gur, Greenberg, Hungerbuhler, & Geshwind, 1982; reviews by Davidson, 1984; Leventhal & Tomarken, 1986; Silberman & Weingartner, 1986). Evidence both from normal (e.g., Davidson et al., 1979; Tucker, Stenslie, Roth, & Shearer, 1981) and from brain-damaged subjects (Bear & Fedio, 1977; Kolb & Milnet, 1981; Robinson & Benson, 1981) indicates that it is specifically the frontal region that shows this differential lateralization, with lett-sided activation observed during certain positive emotions and right-sided activation associated with certain negative emotions. In a series of studies, we have demonstrated the presence of this differential hemispheric asymmetry in newborn and 10month-old infants (Davidson & Fox, 1982; Fox & Davidson, 1986; Fox & Davidson, 1987). These studies examined electro
Re-envisioned Contributions: Experiences of Faculty Employed at Institutional Types that Differ from their Original Aspirations

Guided by the theory of figured worlds, this qualitative study focuses on 18 faculty members employed at community colleges, broad access liberal arts, comprehensives, and regional research universities, who have constructed professionally and personally meaningful careers at institutions that differ from their original aspirations and/or their graduate training. We offer two key findings that highlight how these professors re-envision their careers and contributions by advancing the learning of others and engaging in inquiry for purposes other than publication. In highlighting these two key themes, we expose tensions that participants experienced and navigated as they reenvisioned their careers.
Adenocarcinoma of the small bowel

Cancer of the small bowel is a rare entity but its incidence is rising. Historically, outcome is poor despite apparent curative resection. At present surgery remains the only treatment modality of proven benefit in the management of this disease. Recent data would suggest 5‐year survival rates in the order of 40–50% at all sites of small bowel cancer. To improve upon this, earlier diagnosis with a high index of suspicion and multicentre adjuvant therapy trials are required.
Design issues for MIMO systems in various fading situations

This contribution provides a fresh look at the asymptotic (in terms of number of antennas) design of multiple-antenna wireless systems, with the goal of giving useful insights on the deployment of future MIMO systems. For the i.i. d. Gaussian and double-directional models, we provide guidelines in terms of the repartition of the antennas between the transmitter and the receiver, and study the influence of array geometry on the ergodic mutual information per antenna. Furthermore, we compare the LOS and NLOS situations, and evaluate the relative importance of the LOS component and path loss in Ricean fading, as well as in the low-rank Ricean component case.
IMPACT OF ACADEMIC STRESS AMONG THE MANAGEMENT STUDENTS OF AMET UNIVERSITY - AN ANALYSIS

The study examined the impact of academic stress among the management students. Stress management encompasses techniques to equip a person with effective coping mechanisms for dealing with psychological stress. Students have different expectations, goals and values that they want to fulfill, which is only possible if they are integrated with that of the institution. The objective of the study is to find out the present level of stress, sources of stress and stress management techniques that would be useful for management students. The study takes into account various criteria like physical, psychological, individual, demographical and environmental factors of stress among the management students. The sample comprises of 100 students of AMET Business School, AMET University in Chennai. Data was collected through structured questionnaire by using convenient sampling method.

Finally, both ventral and dorsal regions were modulated during reorienting but significantly only by reorienting after voluntaryshifts,suggestingtheimportanceofamismatchbetweenexpectationandsensoryinput.
Robustness mechanisms in primate societies: a perturbation study

Conflict management mechanisms have a direct, critical effect on system robustness because they mitigate conflict intensity and help repair damaged relationships. However, robustness mechanisms can also have indirect effects on system integrity by facilitating interactions among components. We explore the indirect role that conflict management mechanisms play in the maintenance of social system robustness, using a perturbation technique to ‘knockout’ components responsible for effective conflict management. We explore the effects of knockout on pigtailed macaque (Macaca nemestrina) social organization, using a captive group of 84 individuals. This system is ideal in addressing this question because there is heterogeneity in performance of conflict management. Consequently, conflict managers can be easily removed without disrupting other control structures. We find that powerful conflict managers are essential in maintaining social order for the benefit of all members of society. We show that knockout of components responsible for conflict management results in system destabilization by significantly increasing mean levels of conflict and aggression, decreasing socio-positive interaction and decreasing the operation of repair mechanisms.
Bladder Dysfunction in Diabetes Mellitus

Diabetic cystopathy is a well-recognized complication of diabetes mellitus, which usually develops in middle-aged or elderly patients with long-standing and poorly controlled disease. It may have broad spectrum clinical presentations. Patients may be asymptomatic, or have a wide variety of voiding complaints from overactive bladder and urge incontinence to decreased bladder sensation and overflow incontinence. This review focuses on pathophysiological mechanisms responsible for urologic complications of diabetes and emphasizing on recent developments in our understanding of this condition. We also tried to shed some light on therapeutic modalities like behavioral, pharmacological, and surgical approaches.
Perioperative outcome of patients with esophageal atresia and tracheo-esophageal fistula undergoing open versus thoracoscopic surgery.

INTRODUCTION Thoracoscopic approach for repair of esophageal atresia (EA) and tracheo-esophageal fistula (TEF) has become a standard procedure in many pediatric surgical centers. Thoracoscopic surgery in a newborn is demanding from both the surgeon and the patient. The potential benefits for the newborn are still discussed by neonatologists, pediatric intensive care physicians, and also parents. The aim of our investigation was to clearly define perioperative outcome and complication rates in children undergoing thoracoscopic versus open surgery for EA and TEF repair. PATIENTS AND METHODS We reviewed the records of 68 newborns undergoing surgery for EA and TEF between March 2002 and February 2010. Patient data of open versus thoracoscopic approach were compared regarding operating time, intraoperative as well as postoperative pCO(2)max values, postoperative ventilation time, and complications. Specific patient data are reported with the median and range. Data analysis was done with the JMP(®) 7.0. 2 statistical software (SAS Institute, Cary, NC). RESULTS For the 68 patients, the mean gestational age was 35 weeks (28-41), the median birth weight was 2720 g (1500-3510 g) in the thoracoscopic group and 2090 g (780-3340 g) in the open group. There were 36 girls and 32 boys. Thirty-two children had associated anomalies. Twenty-five children were undergoing a thoracoscopic procedure. In 8 cases, the operation was converted to open thoracotomy. Another 32 children received a thoracotomy. In 11 newborns, a cervical esophagostomy was performed because of long-gap EA and these patients were excluded from the study. Operating time was 141 minutes (77-201 minutes) in the thoracoscopic group and 106 minutes (48-264 minutes) in the thoracotomy group, with significant difference (P=.014). Values of pCO(2)max during operation were 62 mm Hg (34-101 mm Hg) in the thoracoscopic group and 48 mm Hg (28-89 mm Hg) in the open group, with significant difference (P=.014). Postoperative ventilation time was 3 days (1-51 days) in all groups, with no significant difference (P=.79). Early complications were noticed in 9 children undergoing thoracoscopy and in 8 patients of the thoracotomy group, again with no significant difference (P>.05). CONCLUSION Thoracoscopic repair of EA with TEF is justified because of a comparable perioperative outcome to open surgery, competitive operating times, decreased trauma to the thoracic cavity, and improved cosmesis despite skeptical considerations. Complication rates are not higher than in children operated on through a thoracotomy. However, a learning curve has to be taken into account and large experience in minimal invasive surgery is mandatory for this procedure. Larger series have to be expected for a more objective evaluation of perioperative as well as long-term outcomes. To our opinion, the thoracoscopic approach appears to be favorable and could be a future standard.
Page Stream Segmentation with Convolutional Neural Nets Combining Textual and Visual Features

In recent years, (retro-)digitizing paper-based files became a major undertaking for private and public archives as well as an important task in electronic mailroom applications. As a first step, the workflow involves scanning and Optical Character Recognition (OCR) of documents. Preservation of document contexts of single page scans is a major requirement in this context. To facilitate workflows involving very large amounts of paper scans, page stream segmentation (PSS) is the task to automatically separate a stream of scanned images into multi-page documents. In a digitization project together with a German federal archive, we developed a novel approach based on convolutional neural networks (CNN) combining image and text features to achieve optimal document separation results. Evaluation shows that our PSS architecture achieves an accuracy up to 93 % which can be regarded as a new state-of-the-art for this task.
What Have We Learned About Generalized Trust, If Anything?

After discussing issues related to the conceptualization, measurement, and statistical analysis of data on generalized trust, I survey recent empirical work (mainly from about 2000–2007) on this topic. First, results concerning cross-country differences in the level of generalized trust and the dynamics of these levels are presented. Then comes an investigation of empirical work on the determinants of generalized trust, covering contributions focusing on the impact of civic society, quality of institutions, culture and values, and ethnic heterogeneity. In these studies, generalized trust is treated as the dependent variable. After that, I survey recent empirical work on societal impacts of generalized trust, covering research on the impact of generalized trust on economic outcomes, on politics and “good government,” and on the welfare state. Here, generalized trust is treated as an independent variable. I conclude with a short assessment of where we stand and how research on generalized trust may proceed .
