Pengaruh kepimpinan LMX terhadap tingkah laku kewarganegaraan keselamatan dalam kalangan bukan eksekutif

Abdullah HM, Khairudin R, Fatimah wH

Jurnal Psikologi Malaysia, 2014;olume 28:88-97.

This study was carried out to determine the influence of LMX towards the SCB worker dimension in a national automotive company in Malaysia. There were 360 respondents from the automotive company involved in this study. Data collected from respondents were analysed using descriptive (demographic frequencies) and inferential statistics (correlation and regression analysis). The results showed that one of the four independent variables has a positive influence on SCB. In terms of the demographic factors, none of the variables (age, gender and period of service) made any significant difference on LMX and SCB, except the position category. Further suggestions regarding LMX and SCB are discussed based on the findings.

Interval estimations for parameters of gompertz model with time-dependent covariate and right censored data

Kiani K, Arasan J, Habshah Midi

Sains Malaysiana, 2012;41:471-480.

There are numerous parametric models for analyzing survival data such as exponential, Weibull, log-normal and gamma. One of such models is the Gompertz model which is widely used in biology and demography. Most of these models are extended to new forms for accommodating different types of censoring mechanisms and different types of covariates. In this paper the performance of the Gompertz model with time-dependent covariate in the presence of right censored data was studied. Moreover, the performance of the model was compared at different censoring proportions (CP) and sample sizes. Also, the model was compared with fixed covariate model. In addition, the effect of fitting a fixed covariate model wrongly to a data with time-dependent covariate was studied. Finally, two confidence interval estimation techniques, Wald and jackknife, were applied to the parameters of this model and the performance of the methods was compared.

Fulltext Demographic consequences of heterogeneity in conspecific density dependence among mast-fruiting tropical trees

O'Brien MJ, Hector A, Kellenberger RT, Maycock CR, Ong R, Philipson CD, et al.

Proc Biol Sci, 2022 Jun 08;289(1976):20220739.
PMID: 35703055 DOI: 10.1098/rspb.2022.0739

The role of conspecific density dependence (CDD) in the maintenance of species richness is a central focus of tropical forest ecology. However, tests of CDD often ignore the integrated effects of CDD over multiple life stages and their long-term impacts on population demography. We combined a 10-year time series of seed production, seedling recruitment and sapling and tree demography of three dominant Southeast Asian tree species that adopt a mast-fruiting phenology. We used these data to construct individual-based models that examine the effects of CDD on population growth rates (λ) across life-history stages. Recruitment was driven by positive CDD for all species, supporting the predator satiation hypothesis, while negative CDD affected seedling and sapling growth of two species, significantly reducing λ. This negative CDD on juvenile growth overshadowed the positive CDD of recruitment, suggesting the cumulative effects of CDD during seedling and sapling development has greater importance than the positive CDD during infrequent masting events. Overall, CDD varied among positive, neutral and negative effects across life-history stages for all species, suggesting that assessments of CDD on transitions between just two stages (e.g. seeds seedlings or juveniles mature trees) probably misrepresent the importance of CDD on population growth and stability.

Yong SJ, Halim A, Liu S, Halim M, Alshehri AA, Alshahrani MA, et al.

Auton Neurosci, 2023 Dec;250:103132.
PMID: 38000119 DOI: 10.1016/j.autneu.2023.103132

PURPOSE: To address recent concerns of postural orthostatic tachycardia syndrome (POTS) occurring after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (COVID-19) vaccination.
METHODS: We searched PubMed, Web of Science, and Scopus as of 1st June 2023. We performed a systematic review and meta-analysis of pooled POTS rate in SARS-CoV-2-infected and COVID-19-vaccinated groups from epidemiological studies, followed by subgroup analyses by characteristic. Meta-analysis of risk ratio was conducted to compare POTS rate in infected versus uninfected groups. Meta-analysis of demographics was also performed to compare cases of post-infection and post-vaccination POTS from case reports and series.
RESULTS: We estimated the pooled POTS rate of 107.75 (95 % CI: 9.73 to 273.52) and 3.94 (95 % CI: 0 to 16.39) cases per 10,000 (i.e., 1.08 % and 0.039 %) in infected and vaccinated individuals based on 5 and 2 studies, respectively. Meta-regression revealed age as a significant variable influencing 86.2 % variance of the pooled POTS rate in infected population (P

Almaslami F, Aljunid SM, Ghailan K

J Int Med Res, 2018 Apr;46(4):1537-1544.
PMID: 29350090 DOI: 10.1177/0300060517749329

Objectives To assess the demographic characteristics and outcomes of couples undergoing in vitro fertilisation (IVF) treatment at a private hospital in Al Qassim district, Saudi Arabia. Methods For this retrospective study, information was extracted from the hospital electronic database and IVF unit medical records. Results 2259 couples underwent 2703 IVF/ICSI cycles during 2014 to 2016. The utilization rate was approximately 1000 cycle per million of inhabitants. Mean ages ± standard deviation (SD) for women and men were 32.9 ± 5.7 and 39.2 ± 7.4 years, respectively. More couples were diagnosed with secondary infertility (55.2%) than primary infertility (44.8%). Male factor was the commonest single indication for IVF (36.2%). Mean ± SD infertility duration was 4.70 ± 4.03 years. Overall, 949 couples had a successful pregnancy. Age-specific pregnancy rates (PR) were highest for women <35 years (39.8%) and lowest for women >40 years (11.6%). Male age and infertility duration had no effect on PR but sperm source (fresh vs. frozen) and female age had significant impacts. However, fresh sperm was used in 90.6% cycles whereas frozen sperm was used in 9.4% cycles. Conclusions IVF treatment outcomes in the Al Qassim district are within the boundaries of average international success rates. Infertile couples seeking IVF services should be counselled with regard to important prognostic factors.

Impact of socio-demographic factors on the mitigating actions for climate change: a path analysis with mediating effects of attitudinal variables

Masud MM, Akhatr R, Nasrin S, Adamu IM

Environ Sci Pollut Res Int, 2017 Dec;24(34):26462-26477.
PMID: 28948471 DOI: 10.1007/s11356-017-0188-7

Socio-demographic factors play a significant role in increasing the individual's climate change awareness and in setting a favorable individual attitude towards its mitigation. To better understand how the adversative effects of climate change can be mitigated, this study attempts to investigate the impact of socio-demographic factors on the mitigating actions of the individuals (MAOI) on climate change. Qualitative data were collected from a face-to-face survey of 360 respondents in the Kuala Lumpur region of Malaysia through a close-ended questionnaire. Analysis was conducted on the mediating effects of attitudinal variables through the path model by using the SEM. Findings indicate that the socio-demographic factors such as gender, age, education, income, and ethnicity can greatly influence the individual's awareness, attitude, risk perception, and knowledge of climate change issues. The results drawn from this study also revealed that the attitudinal factors act as a mediating effect between the socio-demographic factors and the MAOI, thereby, indicating that both the socio-demographic factors and the attitudinal factors have significant effects on the MAOI towards climate change. The outcome of this study can help policy makers and other private organizations to decide on the appropriate actions to take in managing climate change effects. These actions which encompass improving basic climate change education and making the public more aware of the local dimensions of climate change are important for harnessing public engagement and support that can also stimulate climate change awareness and promote mitigating actions to n protect the environment from the impact of climate change.

Do demographic factors affect the environment? Empirical evidence from the Middle East and North African countries

Haouas I, Haseeb M, Azam M, Rehman ZU

Environ Sci Pollut Res Int, 2023 Jul;30(31):77077-77095.
PMID: 37249784 DOI: 10.1007/s11356-023-27835-z

Every country intends to enhance national production by achieving sustainable development. The purpose of this study is to examine whether there exists any long-run association among environmental deterioration measured by territorial emissions in CO2, demographic factors (total population, population density, and urban population) and some other variables, namely, energy use, per capita income, energy intensity, and industrial value added for the 16 countries from the Middle East and North African (MENA) over 1990-2018. We implemented the generalized method of moments (GMM), fully modified ordinary least square (FMOLS), robust least square estimators, and panel Granger causality techniques for estimation. The empirical estimates reveal that there exists a long run cointegration among the series. Results also exhibit that energy use, per capita income, energy intensity, industrial value added, population density, total population, and urban population have positive effects on CO2 emissions. Furthermore, in each panel, there is bi-directional causality between population density and CO2 emissions, total population and CO2 emissions, and urban population and CO2 emissions. These findings suggest that the policymakers need not exclusively to focus on the transformation of rural labor from an agricultural-based model to urban regions with powerful, dominant industry and services sectors but also related to the changing of rural establishments into urban spaces is required. These changes in demographics involve changes in the demand for additional transportation services, food, shelter, clothing, and other necessities.

Abu Bakar ZH, Damanhuri HA, Makpol S, Wan Kamaruddin WMA, Abdul Sani NF, Amir Hamzah AIZ, et al.

J Alzheimers Dis, 2019;70(s1):S43-S62.
PMID: 30594926 DOI: 10.3233/JAD-180511

BACKGROUND: Many studies on biochemical and psychological variables have aimed to elucidate the association between aging and cognitive function. Demographic differences and protein expression have been reported to play a role in determining the cognitive capability of a population.
OBJECTIVE: This study aimed to determine the effect of age on the protein profile of Malay individuals and its association with cognitive competency.
METHODS: A total of 160 individuals were recruited and grouped accordingly. Cognitive competency of each subject was assessed with several neuropsychological tests. Plasma samples were collected and analyzed with Q Exactive HF Orbitrap. Proteins were identified and quantitated with MaxQuant and further analyzed with Perseus to determine differentially expressed proteins. PANTHER, Reactome, and STRING were applied for bioinformatics output.
RESULTS: Our data showed that the Malay individuals are vulnerable to the deterioration of cognitive function with aging, and most of the proteins were differentially expressed in concordance. Several physiological components and pathways were shown to be involved, giving a hint of a promising interpretation on the induction of aging toward the state of the Malays' cognitive function. Nevertheless, some proteins have shown a considerable interaction with the generated protein network, which provides a direction of focus for further investigation.
CONCLUSION: This study demonstrated notable changes in the expression of several proteins as age increased. These changes provide a promising platform for understanding the biochemical factors affecting cognitive function in the Malay population. The exhibited network of protein-protein interaction suggests the possibility of implementing regulatory intervention in ameliorating Malay cognitive function.

Fulltext The Effects of Adult Ageing and Culture on the Tower of London Task

Phillips LH, Lawrie L, Schaefer A, Tan CY, Yong MH

Front Psychol, 2021;12:631458.
PMID: 33692728 DOI: 10.3389/fpsyg.2021.631458

Planning ability is important in everyday functioning, and a key measure to assess the preparation and execution of plans is the Tower of London (ToL) task. Previous studies indicate that older adults are often less accurate than the young on the ToL and that there may be cultural differences in performance on the task. However, potential interactions between age and culture have not previously been explored. In the current study we examined the effects of age on ToL performance in an Asian culture (Malaysia) and a Western culture (British) (n = 191). We also explored whether working memory, age, education, and socioeconomic status explained variance in ToL performance across these two cultures. Results indicated that age effects on ToL performance were greater in the Malaysian sample. Subsequent moderated mediation analysis revealed differences between the two cultures (British vs Malaysians), in that the age-related variance in ToL accuracy was accounted for by WM capacity at low and medium education levels only in the Malaysian sample. Demographic variables could not explain additional variance in ToL speed or accuracy. These results may reflect cultural differences in the familiarity and cognitive load of carrying out complex planning tasks.

Int J Occup Saf Ergon, 2021 Sep;27(3):714-727.
PMID: 31131712 DOI: 10.1080/10803548.2019.1623454

Introduction. Demographic information is one of the key parameters that organizations utilize to modify their practices in order to respond to the existing risk within work environments. The present article aims to assess the level of safety climate factors as well as to evaluate the influence of personal factors on safety climate in two different-sized industries. Methods. A total of 216 employees in two large and three small and medium-sized chemical manufacturing industries responded to a questionnaire. Descriptive statistics were used to measure the safety climate level; a two-independent-sample Mann-Whitney U test and a Kruskal-Wallis test were run to compare the difference in safety climate scores among different demographic variables. Results. The lower level of safety climate in small and medium-sized industries revealed lower understanding and performance of management and non-management with regard to safety climate compared to the large industries. Additionally, significant mean differences on some safety climate factors among demographic variables were detected in both sizes of industries, emphasizing the important role of the employees' demographic variables on the plants' safety climate. Conclusion. Improving organization-level and group-level safety climates is recommended to improve employees' level of safety climate and control their personal factors.

MyJurnal

Not many attempts have been made in previous studies to understand consumers’ socio-demographic characteristics and their awareness towards organic rice. Knowledge towards organic rice among consumers is fundamental to induce demand and market for organic rice. This study seeks to understand consumers’ awareness towards organic rice in Malaysia. The survey is exploratory in nature and was conducted at major supermarkets in Klang Valley. Data were analysed using descriptive analysis and chi-square analysis using cross-classification techniques, and correlation to determine their relationship, strength and direction of their relationship. The findings showed majority of the respondents (85.6%) have some level of awareness towards organic rice, while only 64.7% planned to consume organic rice in the future. This indicates that awareness of consumers towards organic rice does not necessarily translate to their planning to consume organic rice. Thus, achieving awareness and understanding the linkage between awareness and consumption is fundamental to impacting demand and market for organic rice. The study also showed that the younger respondents have more concern towards organic rice. These findings if well responded to, would definitely have positive implications for the Malaysian organic rice industry.

Fulltext The influence of socio-demographic factors and product attributes on attitudes toward purchasing special rice among Malaysian consumers

International Food Research Journal, 2011;18(3):1135-1142.
MyJurnal

The study investigated socio-demographic factors and product attributes affecting purchase decision of special rice by Malaysian consumer. The primary data were analyzed by using binary logit model.
Demographic factors and consumer preference for special rice (with reference to basmati rice) attributes were identified to affect purchasing behavior for special rice. Size of household, marital status, number of children, household income and gender of consumers are the main socio-demographic factors that significantly influence households’ choices of special rice for home consumption in the Klang Valley area. The findings also suggest that product attributes such as flavor and aroma, availability, brand name and quality also influence the frequent purchasing of Basmati rice among the Malaysian consumers. However price and easy preparation are not significant in influencing the frequent purchasing of Basmati rice since most consumers are aware that special rice such as Basmati is expensive and all rice has to be prepared in a usual way.

Fulltext Development and characterization of 27 microsatellite markers for the mangrove fern, Acrostichum aureum (Pteridaceae)

Yamamoto T, Tsuda Y, Mori GM, Cruz MV, Shinmura Y, Wee AK, et al.

Appl Plant Sci, 2016 Sep;4(9).
PMID: 27672519 DOI: 10.3732/apps.1600042

PREMISE OF THE STUDY: Twenty-seven nuclear microsatellite markers were developed for the mangrove fern, Acrostichum aureum (Pteridaceae), to investigate the genetic structure and demographic history of the only pantropical mangrove plant.
METHODS AND RESULTS: Fifty-six A. aureum individuals from three populations were sampled and genotyped to characterize the 27 loci. The number of alleles and expected heterozygosity ranged from one to 15 and 0.000 to 0.893, respectively. Across the 26 polymorphic loci, the Malaysian population showed much higher levels of polymorphism compared to the other two populations in Guam and Brazil. Cross-amplification tests in the other two species from the genus determined that seven and six loci were amplifiable in A. danaeifolium and A. speciosum, respectively.
CONCLUSIONS: The 26 polymorphic microsatellite markers will be useful for future studies investigating the genetic structure and demographic history of of A. aureum, which has the widest distributional range of all mangrove plants.

Workplace deviant behavior: Does employee psychological job demand and lack of job resources influence employee workplace deviant behavior?

Ili NN, Omar Z, Ahmad A

Jurnal Psikologi Malaysia, 2014;olume 28:39-62.

Employee deviance has received increasing attention in the past decade. Past research have reported that work environment related factors such as organizational support, supervisory support, role conflict, and job demand were associated with deviant behavior The purpose of this paper is to examine the relationship between job demand (psychological job demand), and job resources (social support), and employee workplace deviant behavior. This study adopts a cross-sectional correlation study design. A total of 315 employees were selected using cluster sampling technique participated in this study. Data were collected using a self-administered questionnaire using the drop and collect method. Data were analyzed using descriptive analysis (mean, standard deviation, frequency distribution) to describe the demographic profile and study variables. Correlation and regression analysis was performed to test the relationship between psychological job demand, and social support, and employee workplace deviant behaviors. The result revealed that lack of social support has significant positive influence on employee workplace deviant behavior. The findings suggest that lack of job resources such as social support may drive employees to engage in deviant work behavior. However, high job demand experienced by employees does not drive them towards engaging in deviant work behavior.
