Factors associated with mobile health information seeking among Singaporean women

This study examined effects of age and social psychological factors on women’s willingness to be mobile health information seekers. A national survey of 1,878 Singaporean women was conducted to obtain information on women’s mobile phone usage, experiences of health information seeking, and appraisals of using mobile phones to seek health information. Results showed that young, middle-aged, and older women exhibited distinct mobile phone usage behaviors, health information-seeking patterns, and assessments of mobile health information seeking. Factors that accounted for their mobile information-seeking intention also varied. Data reported in this study provide insights into mobile health interventions in the future

Could sound be used as a strategy for reducing symptoms of perceived motion sickness?

<p>Abstract</p> <p>Background</p> <p>Working while exposed to motions, physically and psychologically affects a person. Traditionally, motion sickness symptom reduction has implied use of medication, which can lead to detrimental effects on performance. Non-pharmaceutical strategies, in turn, often require cognitive and perceptual attention. Hence, for people working in high demand environments where it is impossible to reallocate focus of attention, other strategies are called upon. The aim of the study was to investigate possible impact of a mitigation strategy on perceived motion sickness and psychophysiological responses, based on an artificial sound horizon compared with a non-positioned sound source.</p> <p>Methods</p> <p>Twenty-three healthy subjects were seated on a motion platform in an artificial sound horizon or in non-positioned sound, in random order with one week interval between the trials. Perceived motion sickness (Mal), maximum duration of exposure (ST), skin conductance, blood volume pulse, temperature, respiration rate, eye movements and heart rate were measured continuously throughout the trials.</p> <p>Results</p> <p>Mal scores increased over time in both sound conditions, but the artificial sound horizon, applied as a mitigation strategy for perceived motion sickness, showed no significant effect on Mal scores or ST. The number of fixations increased with time in the non-positioned sound condition. Moreover, fixation time was longer in the non-positioned sound condition compared with sound horizon, indicating that the subjects used more time to fixate and, hence, assumingly made fewer saccades.</p> <p>Conclusion</p> <p>A subliminally presented artificial sound horizon did not significantly affect perceived motion sickness, psychophysiological variables or the time the subjects endured the motion sickness triggering stimuli. The number of fixations and fixation times increased over time in the non-positioned sound condition.</p

A comparative study of competency requirements for port executive in Vietnam and Taiwan

Nowadays, ports have transformed from a purely ship-shore interface into logistical platforms and are also important clusters of economic activities. With this new role, it is critical that port personnel possess necessary competencies to contribute to port efficiency and turn the port into an effective supply chain partner. Despite the importance of this issue, there has been scant research in the literature. In this study, we aim to explore this research issue through a conceptual model of competencies and validated by a survey with port executives both in Vietnam and Taiwan. It was found that port executives need to possess a broad range of competencies relating to business, port and logistics affairs, and management to be successful in the new era

An Application of AHP on Transhipment Port Selection: A Global Perspective

The research presented in this paper applies the Analytic Hierarchy Process (AHP) to reveal and analyse transhipment port selection by global carriers. In all, 47 relevant service attributes were recorded from a literature review. Two rounds of Delphi surveys – followed by brainstorming sessions – were conducted among experts in industry and academia, in order to narrow their number to four main service attributes/criteria comprising 12 sub-criteria. An AHP designed questionnaire survey was distributed to 20 port users, which covered the total population of global ocean container operators, and to 20 transhipment service providers (port operators/authorities). The results of the AHP analysis revealed that both global container carriers and port service providers had a similar perception of the most important service attributes for transhipment port selection. However, the AHP weight ranking of the sub-criteria involved was not identical between the two surveys, providing scope for further adaptation of service providers to users' priorities. Differences in the performance ranking of six major container ports by global carriers, as revealed in the AHP survey, were then combined with the calculated weights for the 12 transhipment port selection sub-criteria to explore critical attributes where transhipment market strategy could focus.
