The purpose of the present study was to find important determinants of perceived role conflict (PRC) by building a regression model. The paper examined the joint linear influences of wife's age, her income, her time for household chores and outside job, her female role perception (FRP), husband's income, his time for household work and outside job, total number of children, child-density, age of youngest child, and age of oldest unmarried girl to the variance of PRC of women. It also examined relative contribution of each of the independent variables controlling the influences of other independent variables to the variance of the PRC. The subjects were 140 women (homemakers—63; working women—77) from Dhaka City. One demographic and work characteristics questionnaire, one FRP Scale (Ilyas & Zaman, 1988), and one PRC Scale (Begun & Tasneem, 1984) were administered by two female interviewers visiting the household of the subjects. Regression analysis indicated that 27.12% of the variance (R 2 change = .2712) of PRC was explained by all the independent variables operating jointly. However, FRP alone explained 20.61% variance of the PRC. Standardized beta indicated that one standard deviation unit change in FRP introduced greatest change ( = -.512) in PRC and one unit change in husband's time for outside job, the least change ( = -.003). Part and partial correlation coefficient also indicated FRP is related negatively to PRC. Thus, FRP is the only independent variable contributing significantly to the variance of the PRC.  相似文献

Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.  相似文献

Intimate partner violence (IPV), an actual or threatened physical, sexual, or psychological abuse by a current or former partner or spouse, is a common global public health issue. Understanding both the prevalence of IPV during pregnancy and its potential impact on the health of pregnant women is important for the development and implementation of interventions to prevent maternal morbidity and mortality. The purpose of this study was to explore the association between maternal experiences of IPV during pregnancy and pregnancy complications. A health‐facility‐based cross‐sectional study was conducted from July 2015 to April 2016 among 400 randomly selected women who were admitted to the postnatal wards of Rajshahi Medical College Hospital for delivery. Data were collected through face‐to‐face interviews using a structured questionnaire. Multivariable logistic regressions were performed to assess relationships between variables of interest after controlling for potential confounders. Results indicated that 39.0% of women reported physical IPV and 26.3% of women reported sexual IPV during pregnancy. Additionally, 69.5% of women experienced medical complications (MCs); of this group, 44.3% experienced obstetric complications (OCs) and 79.3% experienced any pregnancy complication (AC) during their last pregnancy. The experience of physical IPV during pregnancy was significantly associated with the experience of MCs (adjusted odds ratio (AOR): 2.05, 95% confidence interval (CI): 1.15–4.01), OCs (AOR: 4.23, 95% CI: 2.01–7.12) and AC (AOR: 5.26, 95% CI: 2.98–10.52). Women who experienced sexual IPV during pregnancy were also at increased risk of suffering from any MC, any OC, and AC. Maternal experience of IPV during pregnancy is positively associated with pregnancy complications. Preventing IPV directed at pregnant women might reduce maternal morbidity and mortality in Bangladesh.

Children are surrounded by a variety of digital media and are exposed to potential risks that come with such easy accessibility. Learning how to be safe online is an important consideration for both children and their caregivers. The present study proposes an integrated model of online safety based on constructs from protection motivation theory and the health belief model, namely perceived severity of (and susceptibility to) risk, online self-efficacy, online privacy concern, and digital literacy. The study comprised a survey conducted among 420 schoolchildren aged 9–16 years. Using partial least squares-structural equation modelling, the results illustrated the presence of a negative effect of ‘perceived severity of online risk’ toward online risks, whereas the effect of ‘digital literacy’ was found to be positive. Children whose perception of online risks was more severe were less exposed to online risks if they had higher ‘online privacy concerns’ than the children with higher ‘digital literacy’ who are more exposed to online risk. Results of the study show that engaging in safe online behaviour requires children to have a high perception regarding severity of online risks as well as knowledge of online privacy concerns. Online risks and opportunities occur in parallel. Consequently, the factors that increase or decrease risk may also increase or decrease the benefits.  相似文献

The possibilities of adverse drug reactions and disease-related psychosocial implications have led to the current emphasis on health-related quality of life (HRQoL) assessment in epilepsy. The main objective of this study was to determine the impact of various demographic characteristics i.e. gender, age, marital status, ethnic origin, religion, and employment status on HRQoL profiles in Malaysian epilepsy patients. Patients with epilepsy were recruited from ten public hospitals in Sabah, Malaysia. Upon written consents, they completed the Malay Quality of Life In Epilepsy-30 (QOLIE-30) instrument which assesses Seizure Worry, Overall QoL, Emotional Well-Being, Energy/Fatigue, Cognitive Functioning, Medication Effects and Social Functioning. An Overall Score was generated to represent a summarised HRQoL score. Univariate and multiple linear regression analyses were both carried out using SPSS 14 for (1) all patients and (2) patients possessing Poor QoL (Overall Score < median) and Good QoL (Overall Score ≥ median). One-hundred-and-thirteen patients participated in the study. The respondents ranged from 18–76 years with a mean age of 31 years. Majority were Kadazandusuns (n = 46; 40.7%) and many were unmarried (n = 68; 60.2%), Muslims (n = 50; 44.2%) and unemployed (n = 54; 47.8%). Age was the most significant factor across all patients (B = −0.372, t = −2.238, p = 0.027), regardless of Poor or Good QoL level. Older patients (>56 years) fared the worst in many HRQoL areas. Those with Poor QoL were mostly affected by marital status (widowed/divorced) and ethnic origin (Kadazandusun/Chinese). Religion (Buddhism/Hinduism) emerged as the most prominent HRQoL predictor for patients experiencing Good QoL and being Chinese too played a role. These outcomes indicate that specific demographic characteristics are influential in determining the HRQoL of epilepsy patients. Consequently, healthcare professionals could utilise such information in planning the best treatment and care by considering both the medical and psychosocial impacts towards patients. This paper was part of a research project and majority of its components had been presented at the 7th Conference On International Society For Quality Of Life Studies (ISQoLS) 2006, Rhodes University, Grahamstown, South Africa, 17–20 July 2006.  相似文献

This paper explores the potential of data mining as a technique that could be used by malicious data miners to threaten the privacy of social network sites (SNS) users. It applies a data mining algorithm to a real dataset to provide empirically-based evidence of the ease with which characteristics about the SNS users can be discovered and used in a way that could invade their privacy. One major contribution of this article is the use of the decision forest data mining algorithm (SysFor) to the context of SNS, which does not only build a decision tree but rather a forest allowing the exploration of more logic rules from a dataset. One logic rule that SysFor built in this study, for example, revealed that anyone having a profile picture showing just the face or a picture showing a family is less likely to be lonely. Another contribution of this article is the discussion of the implications of the data mining problem for governments, businesses, developers and the SNS users themselves.  相似文献

The present research intends to understand the influence of employee’s perception of psychological contract breach on their organizational citizenship behaviour and trust on employers. The study was carried out in private banks of North Delhi. Data were gathered from 90 junior level executives using convenience sampling method. Result revealed that psychological contract breach significantly predicts organizational citizenship behaviour and trust. The findings imply that the organization needs to understand and manage employee’s psychological contract properly otherwise perception of its breach can jeopardize employee’s citizenship behaviour and also their trust in employer which in turn may affect their job performance.  相似文献

The theory of rough sets starts with the notion of an approximation space, which is a pair (U,R), U being the domain of discourse, and R an equivalence relation on U. R is taken to represent the knowledge base of an agent, and the induced partition reflects a granularity of U that is the result of a lack of complete information about the objects in U. The focus then is on approximations of concepts on the domain, in the context of the granularity. The present article studies the theory in the situation where information is obtained from different sources. The notion of approximation space is extended to define a multiple-source approximation system with distributed knowledge base, which is a tuple (U,RP)Pßf N(U,R_P)_{P\ss_f N}, where N is a set of sources and P ranges over all finite subsets of N. Each R P is an equivalence relation on U satisfying some additional conditions, representing the knowledge base of the group P of sources. Thus each finite group of sources and hence individual source perceives the same domain differently (depending on what information the group/individual source has about the domain), and the same concept may then have approximations that differ with the groups. In order to express the notions and properties related with rough set theory in this multiple-source situation, a quantified modal logic LMSAS D is proposed. In LMSAS D , quantification ranges over modalities, making it different from modal predicate logic and modal logic with propositional quantifiers. Some fragments of LMSAS D are discussed and it is shown that the modal system KTB is embedded in LMSAS D . The epistemic logic S5DnS5^D_n is also embedded in LMSAS D , and cannot replace the latter to serve our purpose. The relationship of LMSAS D with first and second-order logics is presented. Issues of expressibility, axiomatization and decidability are addressed.  相似文献
