    On thermodynamics of N=6 superconformal Chern-Simons theories at strong coupling

    Full text link
    Recently it has been conjectured that N=6, U(N)_{k} \times U(N)_{-k} Chern-Simons theory is dual to M-theory on AdS_4\times S^7/Z_{k}. By studying one-loop correction to the M-theory effective action, we calculate the correction to the entropy of thermal field theory at strong coupling. For large k level, we have also found the alpha' correction to the entropy from the string correction of the type IIA effective action. The structure of these two corrections at strong t'Hooft coupling are different.Comment: 17 pages; v4: Section 4.1 modifie

    This study aims to investigate whether leadership style affects enterprise resource planning (ERP) users’ continuance intention. Continuance intention in ERP at the individual user level is a key attitude for survival in many businesses. The long-term feasibility of an ERP implementation in an organization depends on its continued use rather than its initial use. This paper describes research in progress that proposes an evaluation of the effects of transformational and transactional leadership styles via psychological mechanisms of organizational commitment on continuance intention in ERP in an organization. In this study, continuance intention of ERP is mainly recognized by user satisfaction

    Individuals\u27 Absorptive Capacity in Enterprise System Assimilation

    The capability of an individual to absorb knowledge about enterprise resource planning (ERP) is a critical element in the development of an organisation’s absorptive capacity (ACAP) during assimilation phase of ERP. Prior research have tended to overlook the roles that individuals play in identify external and internal knowledge, assimilate and exploit ERP knowledge. By defining ACAP at the individual level, we seek to enrich our understanding of how individual learn ERP knowledge and how such efforts facilitate the ERP assimilation within organisations. We develop a theoretical model to investigate the assimilation of enterprise systems in the post-implementation stage. Specifically, this model explains how communication climate and top management participation moderates the impact of Individuals’ ACAP on the assimilation of ERP systems

    How Does Contingent Reward Affect Enterprise Resource Planning Continuance Intention? The Role of Contingent Reward Transactional Leadership

    During the past decade, an increased focus on charismatic and transformational leadership has led to a diminished recognition of the importance of transactional leadership behaviours for successful information systems. We say that this is important because recent studies have shown that transactional leadership, in the form of contingent reward behaviour, can have substantial effects on employee attitudes, perceptions and behaviour. Therefore, in this study we discuss how contingent reward transactional leadership behaviour influences enterprise resource planning (ERP) users’ continuance intention by proposing a research model that explains how contingent reward has a positive effect on ERP users’ satisfaction and perceived usefulness which leads to ERP continuance intention. We further argue that distributive justice mediates this relationship. This study calls for managers to pay attention to the importance of contingent reward leadership behaviour in continuous intention of ERP

    Background: Providing and sustaining the mental health of mothers who have experienced a traumatic childbirth have significant impact on the health of the mother, family and society. This study aimed to evaluate the effect of early skin-to-skin contact in the first hour of birth on the mental health of mothers with traumatic childbirth. Methods: This randomized clinical trial was conducted in 2015 on 82 mothers who, based on Diagnostic and Statistical Manual of Mental Disorders (DSM-V-TR) criteria, had experienced a traumatic childbirth. After randomly assigning mothers into groups, the intervention group received early skin-to-skin contact in the first hour after birth, and the control group received the routine procedures. The mental health as an outcome of this study was evaluated using the Persian version of General Health Questionnaire (GHQ-28). Results: The results showed that the mean score of mental health of mothers in the intervention and control groups was significantly different (P < 0.001) and with the passage of time, the mental health status in the intervention group appeared better than that of the control group (P < 0.001).Conclusions: Early skin contact in the first hour of birth not only in normal deliveries but also in traumatic births can have an important and effective role in improving the mental health of the mothe

    Investigating the Effective Factors on the Needle Stick Injuries and Personnel’s Approach in Bahar Medical Education Center in Shahroud During 2009-2018

    Background: The aim of the study was to determine the causes and rate of needle stick injuries among Bahar Hospital in Shahroud during 2009-2018. Methods: This is a descriptive case series study conducted in Bahar educational and research center in Shahroud. The study population included all health care workers and service staff during 2009-2018. Census sampling was performed using health care records of the medical and paramedical group (individual at risk of occupational exposure) from the beginning of January 2009 to the end of December 2018. Data analysis was performed using descriptive statistics (absolute and relative frequency), and t-test and analysis of variances for quantitative values. Results: A total of 246 cases of needle sticks were reported in ten years. Most cases belonged to bachelor's staff (69.1%), nursing job group (69.5%), emergency department and labor (28.9%), equipment of injections (75.6%), injections (45.5%), carelessness (37%), recapping  (24.8%), and at night shift (51.6%) were observed. Bleeding from the injured site was the most common post-exposure action (44.3%). Conclusions: Considering the high prevalence of needle stick among health care workers, instruction of prevention methods, holding educational classes, emphasizing on vaccination, controlling HBV antibody titer, and designing a precise reporting mechanism for personnel is necessary.
