An Empirical Study of Managers’ Intention to Hire Older Workers

The study tested a modified Theory of Planned Behaviour model with an added variable of past experience to predict managers’ intention to hire older workers. Surveyed locations were the western coast of Peninsular Malaysia. A cross-sectional data was collected via personal administered questionnaires surveys (n=468). A response rate of 78% (M=59.6%; F=40.4%) was recorded. Models and hypotheses testing were performed using SEM-PLS. Values from internal consistency reliability tests indicated all values were accepted and demonstrated a high level of reliability. Convergent and discriminant validities were well established. Both tolerance and VIF values suggested no potential collinearity problem. The modified model accounted R2=0.377. The findings suggested that the antecedents and intention were related and that the 3 hypotheses (H1, H2, and H3) were supported. The empirical result derived is expected to bring awareness to business organizations on the benefits of a diversified workforce, a better understanding on the effects of attitudes, subjective norms and past experience on managers’ intention when hiring older workers. Relevant public policy makers are able to, from the outcome of the study, formulate and implement workplace good practices to help prolong older workers work life, which in turn would greatly relief the Government from financial burden due to unemployed older workers. In addition, the result further encourages more future research to enrich the body of knowledge of Malaysian research literature on ageing workforce. &nbsp

Intention to Hire Older Workers: A Predictive Model

Malaysia is currently facing a serious labour shortage as a result of declining employment participation rate from its ageing population. Nevertheless, the utilisation of skilful and experienced older workers requires the willingness of business organizations to hire them. Therefore, this paper examines managers’ intention to hire older workers by using an extended model of the Theory of Planned Behaviour (TPB). Past experience is an additional variable used beside attitude, subjective norm and perceived behavioural control in the TPB. A quantitative method of research is adopted through 55 well-prepared questionnaires. The model and hypotheses are tested using partial least square - structural equation modelling analysis. The result of the survey involved 468 hiring managers from 11 industries and 9 states in Malaysia. The research model accounted for a moderate portion of the variance in future hiring intention (R2=0.392). The findings suggest that the predictive component of attitude, subjective norm, and perceived behavioural control are related to the future hiring intention whereas the past experience predictor found no relation. This study's result makes a valuable theoretical contribution as it positioned at age discrimination on the employment of older workers, and serves to future research with reasonable modification on the areas. This study has practical implication at two-levels: bring awareness to business organizations on ageing workforce and preparatory actions on good workplace practices to eliminate inequalities in the age-diversified workforce

Body weight, height and waist circumference measurements were taken by trained health nurses according to a standard procedure (WHO, 1998). Body Mass Index (BMI) was determined among 33,055 eligible adults, while risk of abdominal obesity based on waist circumference (WC) was obtained from 32,900 individuals. In addition, peripheral muscle wasting was determined using calf circumference (CC) among 4,282 older individuals aged 60 years and above. The national prevalence of normal BMI (BMI 18.5-24.9 kg/m2) was 48.4% (47.7–49.0)*. The prevalence of underweight (BMI <18.5 kg/m2) was 8.5% (8.2–8.9), being higher in rural areas {9.8% (9.2–10.4)} than in urban areas {7.8% (7.4–8.3)}. Meanwhile, 29.1% (28.6–29.7) of the adults were overweight (BMI 25.0-29.9 kg/m2). Among the ethnic groups, Indians had the highest prevalence of overweight followed by Malays and Chinese. In addition, 14.0% (13.6–14.5) of the adults were obese (BMI >30.0 kg/m2). Women had higher obesity prevalence at 17.4% (16.7–18.0) than men at 10.0% (9.5–10.5). In terms of ethnic groups, Indians and Malays had higher obesity prevalence than other groups. By occupation category, housewives showed the highest prevalence of obesity at 20.3% (19.4–21.3). The prevalence of abdominal obesity (WC for women >88 cm and men >102 cm) was 17.4% (16.9-17.9), with women showing higher prevalence {26.0% (25.2-26.8)} than men {7.3% (6.7-7.6}. The prevalence of older persons with peripheral muscle wasting (calf circumference for women < 27.3 cm and men < 30.1 cm) was 19.9% (18.5–21.6), with a higher prevalence of men {23.7% (21.6-25.9)} than women {16.8% (15.1-18.5)} at risk of malnutrition according to this indicator. In comparison, the present national prevalence of underweight of 8.5% was three times lower than that (25.2%) reported in the NHMS II in 1996. In contrast, the prevalence of overweight hasof 14.0% in this study and 12.7% in the MANS were approximately three times the level of 4.4% found in 1996 (NHMS III). This alarming trend calls for serious re-examination of public health programmes for more effective reduction of obesity among Malaysian adults. increased from 16.6% in the NMHS II to 29.1% in the present study. The latter is comparable with the finding of 27.4% reported in another nationally representative sample involving over 5,000 adults namely, the Malaysian Adults Nutrition Survey (MANS) conducted in 2003. It is noted that obesity prevalence of 14.0% in this study and 12.7% in the MANS were approximately three times the level of 4.4% found in 1996 (NHMS III). This alarming trend calls for serious re-examination of public health programmes for more effective reduction of obesity among Malaysian adults

Reliability, technical error of measurements and validity of instruments for nutritional status assessment of children in the Third National Health and Morbidity Survey, Malaysia

The Third National Health & Morbidity Survey, Malaysia 2006 included nutritional status assessment of children. This study estimated the reliability, technical error of measurement (TEM) and validity of those instruments in 130 children below two from a paediatric clinic. Two nurses measured weight (WT) using Tanita digital weighing scale and Seca beam scale and length (LT) using Seca measuring mat and Stadiometer. Absolute mean difference (AMD) and intra-class correlation (ICC) for WT and LT indicated high inter and intra-examiner reliability. However, by Bland and Altman plot, LT were less reliable. Relative TEMs for WT were within acceptable limits whereas that of LT was slightly above the acceptable limits. The AMD and ICC showed that the test instruments were highly valid, but LT was less accurate. This study suggests that WT and LT in children below two using the test instruments were reliable and valid for a community survey. However, LT measurements require special attention

Reliability and Technical Error of Calf Circumference and Mid-half Arm Span Measurements for Nutritional Status Assessment of Elderly Persons in Malaysia

This study sought to examine the reliability of two measurements; Calf Circumference (CC) and Mid-half Arm Span (MHAS). A sample of 130 elderly persons aged 60 years and above seen consecutively in the Kuala Lumpur Hospital outpatient clinic during the period of December 2005 to January 2006, upon consent, were recruited to the study. There was a high degree of reliability for both inter- and intra-examiner (r close to 1). For inter-examiner, on average the CC measurements taken by the first examiner were 0.3 cm lower than that of the second examiner. The upper and lower limit of the differences were +0.4 to –0.9 cm respectively. Inter-examiner MHAS measurements on average by the first examiner were 0.2 cm lower than that of the second examiner. The limits were +1.7 to –2.1 cm. By comparison, the inter-examiner CC measurements were more reliable than the MHAS measurements. For intra-examiner, on average the CC measurements at Time 1 were consistent with Time 2 (mean difference=0) with limits of the difference at + 0.5 cm. MHAS measurements at Time 1 were on average 0.1 cm less than at Time 2 with limits at +1.7 and –1.8 cm. The technical error of measurement (TEM) and coefficient of variation of CC and MHAS for both interexaminer and intra-examiner measurements were within acceptable limits with the exception of MHAS TEM. This study suggests that CC and MHAS measured in elderly persons 60 years and above, using Seca Circumference Tape ® 206, Germany (0.05 cm) are reliable and can be used in a community survey

Evaluation on the effectiveness of organic acids combination against Ganoderma boninense, the causal pathogen of basal stem rot in oil palm

Basal Stem Rot (BSR) disease mainly caused by Ganoderma boninense has become a serious threat to the South East Asia oil palm industry. With no conclusive remedy to date, the oil palm industry is still in search of effective ways to manage this disease. The present work reports the effectiveness of organic acids combination (OAC) in managing Ganoderma infection in oil palm. In this study, the pre-formulated organic acids combination from a product to control BSR caused by Ganoderma was carried out both in the field and nursery. The trial was conducted for a duration of approximately 18 months. The field trial was carried out at Bode Estate of Kretam Plantations Sabah in Sandakan. The possibility of the OAC in preventing the infection from spreading to newly planted seedlings in the area with Ganoderma history was also assessed via nursery trial at Mile 25, estate of Kam Cheong Sdn Bhd. In the field trial, three different sets of protocols i.e.: A (0.4% v/v with 5 rounds of application), B (0.4% v/v with 3 rounds of application), and C (0.5% v/v with 3 rounds of application) of the OAC treatment were applied along with Ganoderma Selective Medium (GSM) analysis, ergosterol content analysis, in vitro antagonistic evaluation and Scanning Electron Microscope (SEM) observation to comprehensively investigate the efficacy of the combination. Protocols A, B and C had significantly reduced the colonisation / amount of ergosterol content (8.832-9.095 μg/g of trunk tissues) in the infected palms in comparison to those Ganoderma infected but left untreated palms (48.956 μg/g of trunk tissues). However, there was no significant difference between the effectiveness among the three protocols in reduction of Ganoderma colonisation till month-12, in which protocol C proved to perform better compared to the other two protocols. There was slight ergosterol content increment in oil palm tissues treated with various protocols of the OAC at month-18, but were much lesser compared to untreated palms. Nonetheless, none of the protocols in application of OAC gave an absolute control of Ganoderma till the end of the trial, as the treated palms remained infected but with much lower ergosterol content compared to untreated palms. Application of the OAC as soil treatment for prevention of Ganoderma infection to seedlings replanted in the area with Ganoderma history in Kam Cheong Estate showed lesser disease incidences compared to those untreated ones. The infected seedlings which were treated by this product also showed lesser amount of ergosterol content which represents lesser colonisation of the pathogenic fungi. However, OAC-treated seedlings still recorded the presence of ergosterol from low to moderate in some of the tested samples. In vitro experiment of OAC and Ganoderma mycelia further elaborates the possible interaction between these organic acids with Ganoderma when in contact with either the tissues or soil. The in vitro results suggest OAC has destructive effect against the mycelia of Ganoderma with SEM evidences of massive damaging effects of the product to the mycelia of the fungi. Based on the GC-MS analysis, the OAC were identified from the products propanoic acid, acetic acid, benzoic acid, sorbic acid and besylic acid

Abdominal obesity in Malaysian adults: National Health and Morbidity Survey III (NHMS III, 2006)

Abdominal obesity (AO) is an independent risk factor for cardiovascular disease, hypertension and diabetes mellitus in adults. There is a lack of data on the magnitude and socio-demographic profile of AO among Malaysian adults at the national level. In the Third National Health and Morbidity Survey (NHMS III) conducted in 2006, AO of adults aged 18 years and above was determined based on the waist circumference as part of the nutritional status assessment. This article reports the prevalence of AO in relation to socio-economic factors and demographic characteristics of adult subjects. Out of a total of 33,465 eligible individuals 18 years and above, waist circumference was measured in 32,900 (98.3%) individuals. The prevalence of AO was assessed using the cut-off points recommended by World Health Organization. The mean waist circumference in men and women was 84.0cm [95% confidence interval (95% CI): 83.8, 84.3] and 80.3cm (95% CI: 80.1, 80.6) respectively. The national prevalence of AO was 17.4% (95% CI: 16.9, 17.9). The identified risks of AO were women (OR: 4.2, 95% CI: 3.8, 4.6), aged 50-59 years (OR: 5.6, 95% CI: 4.0, 7.7), Indians (OR: 3.0, 95% CI: 2.4, 3.8), housewives (OR: 1.4, 95% CI: 1.1, 1.7), subjects with primary education (OR: 1.3, 95% CI: 1.1, 1.5) and ever married (OR: 1.4, 95% CI: 1.2, 1.6). Being the largest population-based study on AO among Malaysians, these findings have important public health implications. There is an urgent need to revise public health policies and programmes aimed at prevention of abdominal obesity especially in the groups at risk

Reliability, technical error of measurements and validity of instruments for nutritional status assessment of adults in Malaysia

The Third National Health & Morbidity Survey, Malaysia 2006 included nutritional status assessment of children. This study was to assess inter-and intra-examiner reliability, the technical error of measurement (TEM) and the validity of instruments for measuring weight, length and waist circumference. A convenience sample of 130 adults working in a selected office setting who fit the inclusion and exclusion criteria participated in the study. Two public health nurses, trained to follow a standard protocol, obtained the measurements. Weight was measured using Tanita digital weighing scale, 318, Japan (0.1 kg) and Seca Beam Scale, Germany (0.01 kg) weighing machines. Height was measured using Seca Bodymeter 206 Germany (0.1cm) and Stadiometer, Germany (0.1cm). Waist circumference was measured using Seca circumference tape, 206, Germany (0.1 cm). By comparison the inter-examiner reliability in descending order would be weight, height and lastly waist circumference. The intra-examiner reliability in descending order would be weight and height followed by waist circumference. Height measurement on average using test instrument reported that it was recording 0.4 cm higher than the reference instrument with upper limit and lower limit at 2.5 and 1.6 cm respectively. The technical error of measurement and coefficient of variation of weight and height for both inter-examiner and intra-examiner measurements are all within acceptable limit (below 5%). The findings of this study supports that weight, height and waist circumference measured in adults 30 years and above using Tanita digital weighing scale, 318, Japan (0.1 kg), Seca Bodymeter 206 Germany (0.1cm) and Seca circumference tape, 206, Germany (0.1 cm) are reliable and valid to be used in a community survey. Limiting the number of examiners especially for waist circumference measurements would yield higher degree of reliability and validity

Nutritional status of children below five years in Malaysia: anthropometric analyses from the third National Health and Morbidity survey III (NHMS, 2006)

The Third National Health and Morbidity Survey (NHMS III) was conducted in 2006 on a nationally representative sample of population in Malaysia. Over 21,000 children aged 0-17.9 years were measured for body weight and stature according to the protocol of the World Health Organization. This article describes the nutritional status of children aged 0-59.9 months. Mean z score for weight-for-age (WAZ), height-for-age (HAZ) and BMI-for-age were compared with the z-scores tables of the WHO standards. The overall prevalence of underweight and stunting of the children were 12.9% and 17.2% respectively. These levels included 2.4% severe underweight and 6.0% severe stunting. In terms of z scores, the age group of 0-5.9 months showed the best nutritional status with mean WAZ of-0.33 (95%CI:-0.52, 0.15) and-0.40 (-0.57, 0.24) for boys and girls respectively, while mean HAZ was 0.64 (0.38, 0.89) for boys and 0.76 (0.54, 0.98) for girls. Mean HAZ and WAZ status was least satisfactory after about 6 months, suggesting a faltering in growth rate at an age that coincides with dependence on complementary feeding. Prevalence of overweight based on BMI-for-age for the sexes combined was 6.4%, while that based on WAZ was 3.4%. The NHMS III results indicate that Malaysian children have better nutritional status compared to children under 5 years in neighbouring countries. In order to meet the targets set in the National Plan of Nutrition (2006-2015), more effective intervention programmes are needed to accelerate the reduction of underweight and stunting, and to arrest the rise of overweight in young children
