Do Sex Differences in the Association between Work Exposure and Health in the Manufacturing Industry Depend on Work Context? Results from the WOLF-Study  [PDF]
Maria Nordin, Malin Bolin
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.58101
Abstract:

The aim of this study is to investigate the associations between work exposure such as psychosocial work factors and work posture, and health in men and women with the same type of occupation in the manufacturing industry. Two follow-ups with a follow-up rate of 67% from the WOrk, Lipids and Fibrinogen (WOLF) cohort from the Northern Sweden were used. The database included 1589 men and 286 women, which is representative of the proportions between men and women in the Swedish manufacturing industry. To be able to understand the importance of work context, the participants were categorized according to work tasks (working with things or symbols). Logistic regression was used for interaction analyses between sex and psychosocial work factors (such as demand, control, social support, role conflict, and work-family conflict) as well as physical work factors (such as work posture), and health outcomes (work overcommitment, fatigue, and neck and back pain). The results showed contextually different patterns of sex different associations between psychosocial work factors and health outcomes. For instance, women were at larger risk of ill-health (in the form of work overcommitment) when working with things, whereas men were at larger risk of both work overcommitment and fatigue when working with symbols. Women working with symbols had a larger risk of neck and back pain due to work-family conflict. The health outcome that was most sensitive to the sex different associations was work overcommitment. In conclusion, the work context matters for sex differences in the association between psychosocial work factors and health and since work overcommitment is a predictor of disease, it should be of interest for the Occupational Health Services and personnel departments to survey.

Social Support and Sleep. Longitudinal Relationships from the WOLF-Study  [PDF]
Maria Nordin, Peter Westerholm, Lars Alfredsson, Torbjorn Akerstedt
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.312A181
Abstract:

Aim: To investigate the relationship between two social support dimensions (network and emotional support) and sleep quality and between two social support sources (at and outside work) and sleep quality. Methods: The three-wave prospective Work Lipids and Fibrinogen (WOLF) study from Northern Sweden was used including 2420 participants who had filled out a questionnaire on working life, life style and health. Sleep quality was assessed by the Karolinska Sleep Questionnaire (KSQ). Structure and function of social support were measured as network support both at and outside work by Availability of Social Integration (AVSI) and emotional support both at and outside work by Availability of Attachment (AVAT). Logistic regression was used, utilizing variables created to assess development over time. Moreover, reversed causation was tested. Results: Improved network support at work decreased the risk of disturbed sleep (OR .65; 95% CI .47 - .90) as did improved emotional support outside work (OR .69; 95% CI .49 - .96). Reporting a constant poor network support at work increased the risk of disturbed sleep (OR 1.53, 95% CI 1.10 - 2.11) as did reporting a constant poor emotional support outside work (OR 1.46; 95% CI 1.02

Impact of Job Crafting on Quality of Care: The Moderating Effect of Commitment  [PDF]
Marina Romeo, Montserrat Yepes-Baldó, Kristina Westerberg, Maria Nordin
Psychology (PSYCH) , 2018, DOI: 10.4236/psych.2018.912151
Abstract: The present study is part of a broader research project aimed at the analysis of the job environment of eldercare and nursing homes employees. In this context, the aim of this research is to analyze the direct effect of job crafting, specifically, task, relational and cognitive crafting, on quality of care, and the moderator effect of commitment on these relationships. A correlational cross-sectional design was used. A non-probabilistic accidental sample of 530 eldercare and nursing home employees was recruited. Standardized instruments were used to assess employees’ job crafting, quality of care and commitment. Regression analyses with PROCESS were used to test the moderated model. Results showed a moderated effect of exchange, values, and affective commitment on the relationship between cognitive job crafting and quality of care, but not on the relationship of task and relational job crafting and quality of care. This study highlights the importance of nurses’ job crafting activities for quality of care. Quality of care depends on cognitive job crafting among nurses with high levels of organizational commitment. Those employees with high levels of need commitment perceived low levels of quality of care, independently of their job crafting.
Modeling Political Belief and Its Propagation, with Malaysia as a Driving Context  [PDF]
Nordin Zakaria
Open Journal of Political Science (OJPS) , 2014, DOI: 10.4236/ojps.2014.42008
Abstract:

We discuss in this paper an agent-based social simulation model that describes the propagation of political belief in Malaysia. Worldview map is used as the representational scheme for political belief. Inter-agent interaction propagates the belief throughout the agent population, subject to similarity of emotion between the interacting agents and their distances apart, and various attributes of the individual agents. Media broadcast may be used by agents in their attempt to extend their reach. Computational experiments made using the model point to its plausibility. Further, it highlights, for the ruling coalition, the importance of both a strong political propaganda machinery and a strong governance in winning the hearts and minds of the electorate.

Revista Panamericana de Salud Pública , 2002, DOI: 10.1590/S1020-49892002000800003
Abstract: objective. great efforts have been made to find effective treatments for back pain. nevertheless, the effectiveness of a particular treatment can depend on patient compliance. the objective of this study was to prospectively investigate whether patients' demographic factors, clinical factors, external barriers in following the treatment, and perceptions of disability, quality of life, depression, and control over health were predictive of compliance with a physical therapy program carried out with patients with low back pain. methods. this was an exploratory prospective cohort study that was carried out in new york city during 1999. all study participants answered a questionnaire at the initial clinical evaluation by a physical therapist and were followed during the treatment. the study assessed compliance with the three treatment regimens that were prescribed for every patient: attending scheduled physical therapy sessions, following a program of home exercises, and watching back-education videotapes. depending on the individual patient, the planned treatment program could last from 2 to 6 weeks. the study employed a battery of instruments to measure patient characteristics that included perceived functional limitations, perceived quality of life, depression, and their beliefs about their health. student's t tests and chi-square tests were used to determine if non- and low-compliant patients differed significantly from high-compliant patients. logistic regression was used to estimate adjusted odds ratios expressing the association of selected variables with compliance. results. we found that 51% of the patients were either noncompliant or low-compliant overall with the low back pain treatment program. there were differences in compliance behavior among the three treatment regimens, with compliance being highest for watching the back-education videotapes and lowest for doing the home exercises. poor compliance overall was positively associated with the expectation o

The objective of this study was to prospectively investigate whether patients' demographic factors, clinical factors, external barriers in following the treatment, and perceptions of disability, quality of life, depression, and control over health were predictive of compliance with a physical therapy program carried out with patients with low back pain. Methods. This was an exploratory prospective cohort study that was carried out in New York City during 1999. All study participants answered a questionnaire at the initial clinical evaluation by a physical therapist and were followed during the treatment. The study assessed compliance with the three treatment regimens that were prescribed for every patient: attending scheduled physical therapy sessions, following a program of home exercises, and watching back-education videotapes. Depending on the individual patient, the planned treatment program could last from 2 to 6 weeks. The study employed a battery of instruments to measure patient characteristics that included perceived functional limitations, perceived quality of life, depression, and their beliefs about their health. Student's t tests and chi-square tests were used to determine if non- and low-compliant patients differed significantly from high-compliant patients. Logistic regression was used to estimate adjusted odds ratios expressing the association of selected variables with compliance. Results. We found that 51% of the patients were either noncompliant or low-compliant overall with the low back pain treatment program. There were differences in compliance behavior among the three treatment regimens, with compliance being highest for watching the back-education videotapes and lowest for doing the home exercises. Poor compliance overall was positively associated with the expectation of barriers in following the proposed treatment, with comorbidity, and with longer duration of treatment in this program. Conclusions. The findings of our study indicate that patient compliance with back pain treatment is a serious and complex problem. Nevertheless, while this study was only an exploratory one, we believe that the results of this study can be used by care providers to identify patients likely to become noncompliant and also by researchers to plan specific studies on the effectiveness of treatment programs for patients with low back pain.
An Investigation of Self-Interference Reduction Strategy in a Spatially Correlated MIMO Channel
Rosdiadee Nordin
Journal of Computer Networks and Communications , 2012, DOI: 10.1155/2012/424037
Abstract: One of the efficient ways to transmit high data rate is by employing a multiple-input multiple-output (MIMO) transmission. One of the MIMO schemes, known as spatial multiplexing (SM), relies on the linear independence data streams from different transmit antennas to exploit the capacity from the fading channels. Consequently, SM suffers from the effect of spatial correlation which is the limiting factor in achieving the capacity benefit that SM can offer. In an attempt to increase the robustness of the SM transmission in a wide range of correlated channels, the use of dynamic subcarrier allocation (DSA) is investigated. The effective signal-to-interference-and-noise ratio (SINR) metric is used as the performance metric to determine the subcarrier quality which can then be utilised in the allocation. Two novel variants of the subcarrier allocation scheme are proposed. It is shown that the DSA-SINR approach improves the BER performance of SM transmission in highly correlated channels environment.
