This paper details the study on the changes in riding behaviour, such as changes in speed as well as the brake force and throttle force applied, when motorcyclists ride over a curve section road using an instrumented motorcycle. In this study, an instrumented motorcycle equipped with various types of sensors, on-board cameras, and data loggers, was developed in order to collect the riding data on the study site. Results from the statistical analysis showed that riding characteristics, such as changes in speed, brake force, and throttle force applied, are influenced by the distance from the curve entry, riding experience, and travel mileage of the riders. A structural equation modeling was used to study the impact of these variables on the change of riding behaviour in curve entry section. Four regression equations are formed to study the relationship between four dependent variables, which are speed, throttle force, front brake force, and rear brake force applied with the independent variables.
The grounding system of a lightning protection scheme is designed basically to avoid arcing and
dangerous step potentials. The grounding impedance of the system varies depending on soil structure and frequency. This paper describes the effect of harmonic impedance (also called frequency dependence of soil) on potential distribution under lightning strike to a metal tower with single grounding path, for different soil types. The results show that the peak value of ground potential rise (GPR) and step voltage (SP) may reach extremely hazardous values even at distances in the order of 90 m from the tower footing, especially when soil resistivity is high. Hence, we emphasise that, in contrast to power grounding, when designing of grounding systems that are meant to handle transient or high frequency currents as well, the frequency dependent soil parameters should be considered to avoid hazardous situations, especially at locations with a high probability of lightning strikes such as metal towers.
Sexual orientation other than heterosexuality is believed to be unnatural, sinful and dangerous in a country like Malaysia that is steadfast in religion and culture. Children sexual orientation has subsequently been a sensitive, challenging, and frightening topic for parents. Past studies have documented the role of nature and nurture in the development of social orientation. Although preliminary studies have found genetic to be a significant factor, it was inconclusive if it was the only factor in determining sexual orientation. Hence, this paper will highlight the role of parents in nurturing sexual orientation of children. Despite lack of studies in local and Western context, the few stud-ies available indicated that a secure attachment bond between parent and child is essential for healthy psychosexual and identity development. Additionally, this paper highlights the importance of communication, unconditional love and support between parent and child throughout the developmental stages leading to adulthood. Furthermore, this paper will briefly discuss possible treatment options for children with sexual orientation issues and its impact on chil-dren psychological health and well-being. This paper will conclude with suggestions on future research to further understand the development of sexual orientation in children.
Background: The socio-psychological impact of COVID-19 has affected the whole world. Bangladesh, one of the most dangerous places as stated by WHO, was first infected at the beginning of March 2020, later than other countries. Bangladesh is now one of the 20 most affected countries in the world, but the psychological effects for university students during the epidemic period are not researched. Design and methods: To address this gap, the present study attempts to discover the socio-psychological impact of COVID-19 on university students in Bangladesh. We conducted an online survey using a questionnaire with a simple random sampling technique and we received 474 responses. Results: In this study, numerous psychological concerns were reported. The study is limited to university students, which may affect the generalizability of the research. Conclusions: Our findings suggest a need to build awareness of the mental health implications of the pandemic for university students.
Research in stalking perceptions has shown certain relational biases, in which people tend to view ex-partner stalkers to be less dangerous than stranger or acquaintance stalkers. These findings are in direct contrast to those of real-life cases whereby ex-partner stalkers pose a greater threat. In addition, although stalking is recognized as a global social problem, most studies have been based on samples drawn from Western, educated, industrialized, rich, and democratic countries. The current study examined whether the prior relationship between the stalking perpetrator and target influences people's perceptions of stalking and whether cross-national differences exist between participants based in Malaysia (where there is currently no law that criminalizes stalking) and England (where stalking has been outlawed since 1997). In a 3 × 2 between-subjects design, 294 Malaysian participants and 170 English participants were presented with a vignette describing a stalking scenario in which the perpetrator was depicted as a stranger, acquaintance, or ex-partner. Participants judged the extent to which the perpetrator's behavior constitutes stalking; necessitates police intervention; would cause the victim alarm or personal distress; would cause the victim to fear the use of violence; and can be attributed to encouragement on the part of the victim. Results showed that typical relational biases existed in both samples, but Malaysian participants were less likely than their English counterparts to label any harassing scenario as serious. Perceptions of victim responsibility were found to mediate the effect of prior relationship and nationality on participants' perceptions. The findings point to the urgency of better cross-cultural understanding of harassment behavior as well as legislations against stalking.
Smoking among rural adolescents in Malaysia is on the rise with a significant difference seen between urban and rural youths. Therefore, this study was carried out to determine a predictive model of smoking among the rural-school adolescents population in Malacca, Malaysia. An unmatched case-control study was conducted in 2010 involving 484 cases and 444 controls of Form Two students in Malacca, Malaysia, using cluster sampling. Smoking was the dependent factor of this study while the independent factors were individual, family, school and environment. Data were obtained through a self-administered questionnaire. The response rate of the study was 100% whereas the smoking prevalence was 20.9%. Binary logistic regression was used to determine the smoking predictive model. Strong predictors of smoking behaviour were: influenced by artistes who smoke (Adjusted OR=8.67, 95% CI 5.53-13.58); the male gender (Adjusted OR=6.7, 95% CI 4.14-10.83); Muslim (Adjusted OR=4.46, 95% CI 2.36-8.44); and the belief that smoking is not dangerous when the teacher is seen smoking as well (Adjusted OR=3.95, 95% CI 2.19-7.10). Other predictors were: being offered cigarettes by friends (Adjusted OR=2.81, 95% CI 1.79-4.42); the belief that smoking will relax the mind (Adjusted OR=2.45, 95% CI 1.33-4.51); having friends who smoke (Adjusted OR=2.32, 95% CI 1.29-4.81); forced by friends to smoke (Adjusted OR=2.17, 95% CI 1.15-4.12); have heard of the national No-Smoking Campaign (Adjusted OR=1.89, 95% CI 1.06-3.37); have problems with the school management (Adjusted OR=1.75, 95% CI 1.07-2.88); parental consent to watch sexual activities, drug use or violence on television or at the cinema (Adjusted OR=1.73, 95% CI 1.06-2.83); and have lunch in school (Adjusted OR=1.58, 95% CI 1.04-2.41). This paper ends with the recognition of the need for intervention in dismantling the predictors that can lead to the development of smoking among Malaysian adolescents in rural schools. of different pathological entities.
