    Collective Coordinate Approach to the Dynamics of Various Soliton-Obstruction Systems

    Full text link
    Various soliton-obstruction systems have been studied from analytical perspective. We have used collective coordinate to approach the dynamics of solitons as they meet a potential obstruction in a form of square barriers and holes for three models in (1+1) dimensions, namely: λϕ4\lambda\phi^{4} model, deformed Sine-Gordon model, and a model that give rise to Q-ball solution. We have shown that our approximated field solution is valid enough to describe the behaviour of solitons scattering off a potential obstruction.Comment: 26 pages, 18 figure

    The purpose of this study is to investigate the current status and the challenges of Bahraini women in the financial and banking sector; this sector is in continuous growth and needs to invest in human resources properly to attract talents. To enhance women’s access to senior positions in this sector, it must acknowledge the factors that influence women leadership, where the significance of this study stands out. The study presents how different factors affect the mainstreaming of women progressing to the top-level management. The study followed both quantitative and qualitative methods in data collection, and three different types of survey have been used in the study. The first questionnaire was directed towards Bahraini working women, the second questionnaire was directed towards Bahraini women who have left the sector, and these two questionnaires contained implicit references to the factors of the study. The third questionnaire was directed towards the human resource managers in the financial and banking sector. The total number of Bahraini employees in this sector is 14,675, with about 37% Bahraini women, which represents 25% of the total workforce (Bahrainis and expatriates). The results illustrated that approximately 8% of women reached the Board of Directors and 4.5% of Bahraini women among the Bahraini workforce attained the position of CEO. According to the findings of the study, the most significant factor affecting Bahraini women in the workplace was “the need for women in leadership positions”. The factor with the lowest response was “fringe benefits”. In contrast, the factor relating to “family concerns affecting women” was less significant. Recommendations were made to guide every women on workforce participation and the decision-makers to try remove all or some of the barriers that might hinder women from reaching those positions, aiming to provide women equal access opportunities to leadership positions in the this essential sectors and other sectors in the future

    Sensory texture of date fruits as a function of physicochemical properties and its use in date classification

    Get PDF
    Eight descriptive sensory textural attributes of whole date fruit were evaluated by twenty trained panel members and correlated with sixteen physicochemical properties. All sensory parameters, except gumminess, significantly correlated (Ps<0.05) with pectin, crude fibre, and moisture content. In addition, sensory hardness, cohesiveness, elasticity, and resilience correlated significantly with length of whole fruit (P<0.05), sensory adhesiveness with glucose content (P<0.05), sensory chewiness with mass of whole fruit (P<0.05), and sensory gumminess with fructose, glucose, and total sugar content (P<0.10). Sweetness, however, correlated only with moisture content (P<0.05). CA and the biplot (i.e. including all products, their sensory texture and physicochemical attributes) generated through PCA recognized three groups of dates as hard-chewy, soft-(medium-chewy), and soft-(non-adhesive)

    Soliton-potential interaction in the nonlinear Klein-Gordon model

    Full text link
    The interaction of solitons with external potentials in nonlinear Klein-Gordon field theory is investigated using an improved model. The presented model has been constructed with a better approximation for adding the potential to the Lagrangian through the metric of background space-time. The results of the model are compared with another model and the differences are discussed.Comment: 14 pages,8 figure

    Occupational Burnout Among Omani Physicians Across Different Stages of Their Career

    Get PDF
    The occupational psychology literature indicates that physicians are at an elevated risk of burnout and mental distress. Notably, there is a lack of contribution to this field from Arabic and Islamic cultures. This commentary critically analyses the contribution of twelve published papers to the field of occupational psychology, focusing primarily on stress, health, and wellbeing. The overarching aim is to examine the scale and determinants of occupational burnout among Omani physicians across various stages of their careers using quantitative research methods. Following an introduction and contextualisation, the synthesis of published work proceeds in three chapters. Firstly, four published papers report how mental health and psychological distress are conceptualised among Omani healthcare workers and the public. Secondly, five publications address occupational burnout, the overlap with depressive symptoms, and psychological distress during the COVID-19 pandemic. Thirdly, three publications focus on burnout moderators among young Omani physicians: personality traits, emotional intelligence, and preparedness for hospital work. The findings revealed that burnout is common among Omani physicians, particularly during residency training. Long working hours and pre-clinical stage predicted burnout in regression analysis. However, the prevalence rates in our setting were lower than those reported in the international literature. Also, the published work highlighted the adverse effects of mental health stigma, prevalent in Oman, on willingness to disclose and seek help for psychological distress. Besides, the results highlighted the relationship between surgical speciality and psychoticism. Also, emotional intelligence correlated with specific demographic, including the female gender, while Omani physicians who graduated from international medical school endorsed a high level of preparedness for clinical work. Considering the methodological and theoretical limitations of the published work, conducting a prospective mixed-methods study is vital to scrutinise the burnout construct and its discriminant validity from clinical depression while paying attention to the cross-cultural factors. Moreover, future work should investigate factors improving work engagement and mitigating burnout in the Omani healthcare setting. The publications make an original contribution to the knowledge by culturally re-contextualizing burnout research and advancing the literature on occupational burnout via analysis of: (i) the magnitude and correlates of burnout in Omani physicians; (ii) moderating variables such as personality traits, emotional intelligence; and (iii) preparedness for clinical work. From a practical aspect, the published work has informed several initiatives and interventions to promote wellness and mitigate burnout at both the individual and organisational levels in Oman

    Social Network and Privacy

    Whiles some use the internet basically for commerce, other use for educational purposes whiles to others, it is all about entertainment. The internet can therefore be likened to a blank check, which serves different purposes as and how a person wants to define it. The user variety of the internet notwithstanding, recent studies have actually confirmed that an aspect of internet usage that seem to have caught up with over 70% of all internet users is the phenomenon of social media networking (Compaine and Gomery, 2011). The research paper was conducted with the aim of finding the privacy risks associated with the use of social networking sites and for the practice of social media networking. To realize this aim, five major objectives were set, based on which research questions were developed. The research questions became a guide for the researcher to collect primary and secondary data, with particular emphasis on primary data collection, where a questionnaire was prepared for 50 respondents selected from a university campus. All 50 respondents were users of social networking sites and had strong academic background in journalism and communication, putting them in a position to provid well informed answers to the questions to the respondent. The primary data collection emphasized largely on the attitude of the respondents towards privacy issues whiles using social networking sites. The primary data collection exercise was also committed to knowing the depth of knowledge on privacy issues with social media networks. Through secondary data collection also, the researcher had the opportunity of knowing what the hosts of social networking sites are doing to protect the privacy of users
