  3. Fulltext Gender differences in socioeconomic returns to family migration in Malaysia: the role of family decision making versus labor market stratification
    Chattopadhyay A
    Gender Issues, 2000;18(2):29-47.
    PMID: 12296212 DOI: 10.1007/s12147-000-0009-y
    In this article the author examines gender differences in the effect of family migration on socioeconomic attainment in Malaysia. The analysis discerns the relative importance of gender roles in household migration decisions, compared to gender stratification in the labor market. The Malaysian economy has undergone rapid industrialization and great structural changes which have opened up new economic opportunities, particularly for women. Despite the somewhat advantaged position of women compared to men in the Malaysian labor market, the author finds that men experience much greater socioeconomic gains than women from family migration. Hence indicating that family migration decisions in Malaysia, rather than optimizing family gains, compensate for the gender effect in the labor market. However, the gains of Malaysian men are more assured when they move alone. Data for the study come from the second round of the Malaysian Family Life Survey.

  4. Family migration and the economic status of women in Malaysia
    Chattopadhyay A
    Int Migr Rev, 1997;31(2):338-52.
    PMID: 12292875 DOI: 10.1177%2F019791839703100204
    "The impact of family migration on women's economic position in a developing country setting is an area that has received relatively little research attention. Incorporating a lifetime perspective, this study makes use of the retrospective migration histories of husbands and wives from the second round of the Malaysian Family Life Survey to estimate how joint migration with the husband affects women's socioeconomic achievement. The findings show that family migration depresses the chances of working, but it does not significantly reduce socioeconomic attainment of those who do work. However, when a woman migrates with her husband she does forgo the substantial advantage she could have derived had she moved alone."

  5. Gender, migration, and career trajectories in Malaysia
    Chattopadhyay A
    Demography, 1998 Aug;35(3):335-44.
    PMID: 9749325
    With data from the Malaysian Family Life Survey, I use a continuous-state hazards model to study the impact of migration on the dynamics of individuals' careers. I distinguish between the effects of family migration and solo migration by gender. The results show that migration alters the career trajectory primarily by accelerating the process of occupational mobility rather than by increasing the level of occupational attainment. Further, the effect of migration on careers varies by type of migration, especially for women. Male-female differences in the outcome of family migration, however, are visible only in transitions into and out of employment.

  6. Fulltext Population genetics and demography of the coral-killing cyanobacteriosponge, Terpios hoshinota, in the Indo-West Pacific
    Chow SW, Keshavmurthy S, Reimer JD, de Voogd N, Huang H, Wang JT, et al.
    PeerJ, 2022;10:e13451.
    PMID: 35669953 DOI: 10.7717/peerj.13451
    The first occurrence of the cyanobacteriosponge Terpios hoshinota was reported from coral reefs in Guam in 1973, but was only formally described in 1993. Since then, the invasive behavior of this encrusting, coral-killing sponge has been observed in many coral reefs in the West Pacific. From 2015, its occurrence has expanded westward to the Indian Ocean. Although many studies have investigated the morphology, ecology, and symbiotic cyanobacteria of this sponge, little is known of its population genetics and demography. In this study, a mitochondrial cytochrome oxidase I (COI) fragment and nuclear ribosomal internal transcribed spacer 2 (ITS2) were sequenced to reveal the genetic variation of T. hoshinota collected from 11 marine ecoregions throughout the Indo-West Pacific. Both of the statistical parsimony networks based on the COI and nuclear ITS2 were dominated by a common haplotype. Pairwise F ST and Isolation-by-distance by Mantel test of ITS2 showed moderate gene flow existed among most populations in the marine ecoregions of West Pacific, Coral Triangle, and Eastern Indian Ocean, but with a restricted gene flow between these regions and Maldives in the Central Indian Ocean. Demographic analyses of most T. hoshinota populations were consistent with the mutation-drift equilibrium, except for the Sulawesi Sea and Maldives, which showed bottlenecks following recent expansion. Our results suggest that while long-range dispersal might explain the capability of T. hoshinota to spread in the IWP, stable population demography might account for the long-term persistence of T. hoshinota outbreaks on local reefs.

  7. Fulltext Healthcare in Asia: a perspective from primary care at the gateway to a continent
    Jiwa M, Othman S, Hanafi NS, Ng CJ, Khoo EM, Chia YC

    PMID: 23113999
    Malaysia has achieved reasonable health outcomes even though the country spends a modest amount of Gross Domestic Product on healthcare. However, the country is now experiencing a rising incidence of both infectious diseases and chronic lifestyle conditions that reflect growing wealth in a vibrant and successful economy. With an eye on an ageing population, reform of the health sector is a government priority. As in other many parts of the world, general practitioners are the first healthcare professional consulted by patients. The Malaysian health system is served by public and private care providers. The integration of the two sectors is a key target for reform. However, the future health of the nation will depend on leadership in the primary care sector. This leadership will need to be informed by research to integrate care providers, empower patients, bridge cultural gaps and ensure equitable access to scarce health resources.

  8. Fulltext Serotype distribution of invasive, non-invasive and carried Streptococcus pneumoniae in Malaysia: a meta-analysis
    Lister AJJ, Le CF, Cheah ESG, Desa MNM, Cleary DW, Clarke SC
    Pneumonia (Nathan), 2021 May 25;13(1):9.
    PMID: 34030731 DOI: 10.1186/s41479-021-00086-7
    BACKGROUND: Pneumococcal pneumonia is the leading cause of under-five mortality globally. The surveillance of pneumococcal serotypes is therefore vital for informing pneumococcal vaccination policy and programmes. Pneumococcal conjugate vaccines (PCVs) have been available as an option in the private healthcare setting and beginning December 2020, PCV10 was incorporated as part of routine national immunisation programme (NIP) in Malaysia. We searched existing literature on pneumococcal serotype distribution across Malaysia to provide an overall view of this distribution before the implementation of PCV10.

    METHODS: Online databases (PubMed, Ovid MEDLINE and Scopus), reference lists of articles identified, and grey literature (Malaysian Ministry of Health website, WHO website) were systematically searched for relevant literature on pneumococcal serotype distribution across Malaysia up to 10th November 2020. No lower date limit was set to maximise the number of target reports returned. Results of serotypes were split by age categories, including ≤5 years, > 5 years and unreported for those that did not specify.

    RESULTS: The search returned 18 relevant results, with a total of 2040 isolates. The most common serotypes across all disease types were 19F (n = 313, 15.3% [95%CI: 13.8-17.0]), 23F (n = 166, 8.1% [95%CI: 7.0-9.4]), 14 (n = 166, 8.1% [95%CI: 7.0-9.4]), 6B (n = 163, 8.0% [95%CI: 6.9-9.2]) and 19A (n = 138, 6.8% [95%CI: 5.8-7.9]).

    CONCLUSION: Four of the most common serotypes across all isolate sources in Malaysia are covered by PCV10, while PCV13 provides greater serotype coverage in comparison to PCV10. There is still a need for surveillance studies, particularly those investigating serotypes in children under 5 years of age, to monitor vaccine effectiveness and pneumococcal population dynamic following implementation of PCV10 into routine immunisation.

  11. Fulltext Pre-extinction Demographic Stability and Genomic Signatures of Adaptation in the Woolly Rhinoceros
    Lord E, Dussex N, Kierczak M, Díez-Del-Molino D, Ryder OA, Stanton DWG, et al.
    Curr Biol, 2020 10 05;30(19):3871-3879.e7.
    PMID: 32795436 DOI: 10.1016/j.cub.2020.07.046
    Ancient DNA has significantly improved our understanding of the evolution and population history of extinct megafauna. However, few studies have used complete ancient genomes to examine species responses to climate change prior to extinction. The woolly rhinoceros (Coelodonta antiquitatis) was a cold-adapted megaherbivore widely distributed across northern Eurasia during the Late Pleistocene and became extinct approximately 14 thousand years before present (ka BP). While humans and climate change have been proposed as potential causes of extinction [1-3], knowledge is limited on how the woolly rhinoceros was impacted by human arrival and climatic fluctuations [2]. Here, we use one complete nuclear genome and 14 mitogenomes to investigate the demographic history of woolly rhinoceros leading up to its extinction. Unlike other northern megafauna, the effective population size of woolly rhinoceros likely increased at 29.7 ka BP and subsequently remained stable until close to the species' extinction. Analysis of the nuclear genome from a ∼18.5-ka-old specimen did not indicate any increased inbreeding or reduced genetic diversity, suggesting that the population size remained steady for more than 13 ka following the arrival of humans [4]. The population contraction leading to extinction of the woolly rhinoceros may have thus been sudden and mostly driven by rapid warming in the Bølling-Allerød interstadial. Furthermore, we identify woolly rhinoceros-specific adaptations to arctic climate, similar to those of the woolly mammoth. This study highlights how species respond differently to climatic fluctuations and further illustrates the potential of palaeogenomics to study the evolutionary history of extinct species.

  14. Species composition and population dynamics of thrips (Thysanoptera) in mango orchards of northern peninsular Malaysia
    Aliakbarpour H, Che Salmah MR, Dieng H
    Environ Entomol, 2010 Oct;39(5):1409-19.
    PMID: 22546435 DOI: 10.1603/EN10066
    Thrips are key pests of mango, Mangifera indica (L.), in Malaysia, including the Northern Peninsular. As Penang has year-round equatorial climate and high of rainfall, the populations of thrips may be subject to variations in composition and size. With a goal of developing an appropriate control strategy, a survey was conducted in Penang to determine species composition and abundance in relation to some environmental factors. Sprayed and unsprayed orchards were sampled on weekly basis through two flowering seasons of 2009 using CO(2) collection technique. Larval population falling into the ground to pupate and adults emerging from the soil were investigated in both orchards. Thrips hawaiiensis (Morgan) and Scirtothrips dorsalis (Hood) were the most prevalent species in the sprayed and the unsprayed orchards, respectively. The abundance of thrips was high during the flowering period of the dry season and decreased during the flowering period of the rainy season. This latter period coincided with decreased temperature and increased relative humidity. Percentage of adult emergence from the soil was lower in the rainy season than recorded in the dry season in both orchards. Taken together, these observations suggest that T. hawaiiensis and S. dorsalis are the main thrips species pests of mango panicles in Penang. Direct control with insecticides focusing on these two species may help to reduce cosmetic injuries and other damages on mango fruits.

  15. Fulltext Ethnicity and infant mortality in Malaysia
    Dixon G
    Asia Pac Popul J, 1993 Jun;8(2):23-54.
    PMID: 12287522
    PIP: Malaysian infant mortality differentials are a worthwhile subject for study, because socioeconomic development has very clearly had a differential impact by ethnic group. The Chinese rates of infant mortality are significantly lower than the Malay or Indian rates. Instead of examining the obvious access to care issues, this study considered factors related to the culture of infant care. Practices include the Chinese confinement of the mother in the first month after childbirth ("pe'i yue") and Pillsbury's 12 normative rules for Malaysian Chinese care. Malay practices vary widely by region and history. Indian mothers are restricted by diet. Data-recording flaws do not permit analysis of Sarawak or Sabah. The general assumption that Western medicine favors better health for mothers and infants is substantiated among peninsular communities, however, there are also negative impacts which affect infant mortality. The complex interaction of factors impacting on infant mortality reported in seven previous studies is discussed. A review of these studies reveals that immediate causes are infections, injuries, and dehydration. Indirect causes are birth weight or social and behavioral factors such as household income or maternal education. Indirect factors, which are amenable to planned change and influence the biological proximate determinants of infant mortality, are identified as birth weight, maternal age at birth, short pregnancy intervals or prior reproductive loss, sex of the child, birth order, duration of breast feeding and conditions of supplementation, types of household water and sanitation, year of child's birth, maternal education, household income and composition, institution of birth, ethnicity, and rural residence. Nine factors are identified empirically as not significant: maternal hours of work in the child's first year, maternal occupation, distance from home to workplace, presence of other children or servants, incidence of epidemics in the child's first year of life, community types of sanitation, prices and availability of infant foods, and access to various types of medical care. Future empirical study should consider factors such as class differences, place of residence, or extent of illiteracy as underlying or related to ethnicity. Policy-makers should be aware that future decline in infant mortality rates may depend on the blending of traditional with modern practices.

  17. Muslim refugees in Southeast Asia, the Malaysian response
    Dorall RF
    Asian Migr, 1988 May-Jun;1(3):88-93.
    PMID: 12281348
    This article surveys the arrivals of Muslim refugees from countries in Southeast Asia who have not only come to Malaysia for political refuge, but who have also stayed on, in many instances integrating into the local Muslim community. The author concludes that Burmese, Thai, and Filipino Muslim refugee-cum-migrants, and the estimated 500,000 illegal Indonesian migrant workers in East and Peninsular Malaysia make the presence of economic migrants in Malaysia's towns and rural sectors a far more pressing concern to Malaysians than that posed by the arrival of genuine political refugees. Only the Indonesians present in Malaysia are consistently termed by all parties as illegal migrants and some of them have been subjected to well-publicized deportation by the Malaysian immigration authorities. Sympathy for fellow-Muslims in distress explains Malaysia's open-door policy to Muslim refugees. The Koran specifically enjoins Muslims to assist Muslim refugees who have been persecuted by others. However, the necessity to maintain regional political and military alliances, principally as a bulwark against Communism, and the Malay--Non-Malay, Muslim--Non-Muslim dichotomy in Malaysia which almost evenly divides Malaysia's 16 million population into mutually antagonistic halves, results in any overt public policy in favor of Malays and Muslims to be immediately denounced by the other half of the population as a move against the Non-Malays and Non-Muslims. Without political and media attention, the refugees live wherever they can find work, as do hundreds of thousands of mainly Indonesian illegal migrant workers. They surreptitiously get their children admitted to public schools, and through bribery, can even get Malaysian identification papers. Malaysia is a relatively tranquil haven for Malaysia's Muslim refugees compared to their homelands, but their continued stay remains dependent on the ever-present struggle for more equitable sharing of political and economic power between the different ethnic groups in Malaysia. At present, it is deemed inopportune to discuss publicly the issue of Muslim refugees in Malaysia. To do so would be to invite strong emotional responses from Malaysian Muslim groups objecting to refugee repatriation to what they see as continued persecution in Southeast Asia's non-Muslim countries, and from non-Muslim Malaysians who see in their continued presence a possible long-term demographic threat. Furthermore, the presence of Muslim evacuees granted refugee status brings painful memories as to why non-Muslim refugees principally from Indochina were denied such a similar privilege.

  18. Fulltext Nutrition and ecosystems in Sarawak: The role of the areca nut
    Strickland SS, Duffield AE
    Asia Pac J Clin Nutr, 1998 Dec;7(3/4):300-6.
    PMID: 24393688
    The effects of population pressure on agricultural sustainability in the delicate tropical and subtropical ecosystems have often been thought to explain high prevalence rates of malnutrition in rural South-East Asia. However, recent studies in rural Sarawak suggest that processes of modernisation have resulted in increased variations in energy nutritional status in adults. A contributory factor may be consumption of the areca nut (Malay pinang, of the palm Areca catechu). This is thought to influence energy balance through effects on appetite and resting metabolic rate. Body mass index (BMI, kg/m2) data for 325 Iban men and 438 non-pregnant Iban women, measured in 1990 and again in 1996, have been analysed in relation to areca use, smoking behaviour, socio-economic status, and reported morbidity. Body composition derived from skinfold thickness measurements for 313 men and 382 women was also analysed. The results suggest that use of areca nut is associated with significantly lower age-related increments in BMI and percentage body fat in women after allowing for age, smoking, reported morbidity, and confounding socio-economic factors. Therefore, the impact of recent economic and social development seen in rising prevalences of 'over-nutrition' may be modulated by use of the areca nut.

    PMID: 12315536
    "The present paper attempts to provide an analytical profile of development and human resources in [12] selected [Islamic] countries." The countries--Bangladesh, Somalia, Pakistan, Indonesia, Egypt, Turkey, Malaysia, Algeria, Iraq, Saudi Arabia, Kuwait, and United Arab Emirates--vary in income levels from low to high and in population size from 1 million to 159 million. Using data from the World Bank and the Population Council, comparisons are made on the basis of mortality and fertility levels, family size, income, urbanization, labor force size and growth, education, nutrition, and health. Governmental policy changes and future directions are discussed.

  20. Gender and risk of depression in Saudi Arabia, a systematic review and meta-analysis
    Alibrahim OA, Al-Sadat N, Elawad NA
    J Public Health Afr, 2010 Sep 01;1(1):e7.
    PMID: 28299041 DOI: 10.4081/jphia.2010.e7
    Depression is one of the leading causes of mortality and morbidity worldwide. In the year 2000 depression accounted for 4.4% of the global disability adjusted life years (DALYs). The Kingdom of Saudi Arabia (KSA) has a population of 28 million people and is one of the countries experiencing demographic transition in its population structure. Improvements in socioeconomic status have been shown to be associated with increased chronic diseases including chronic mental diseases like depression, but still there is no comprehensive review summarizing the various reports currently existing in the literature. Although individual studies within Saudi Arabia have reported prevalence rates and risks, the quality of such studies need to be subjected to rigorous assessment and their findings pooled to give combined weighted evidence that will provide basis for targeted intervention. Pooled risks have the advantage of adjusting inherent variations within sampled populations and therefore providing more reliable estimates even though there are concerns about possible magnification of smaller individual risks.
