THE INFLUENCES OF JOB PERFORMANCE, WORK-LIFE BALANCE AND ORGANIZATIONAL JUSTICE ON EMPLOYEES’ CAREER SATISFACTION

Purpose of study: This study is conducted to identify the relationships between job performance, work-life balance and organizational justice towards employee's career satisfaction from one of the manufacturing companies in the north of Malaysia. Methodology: The study is done by utilizing a random sample of 240 employees in the company. Type of investigation is a correlation study and it is cross-sectional on time horizon. The unit of analysis is an individual level; therefore, all employees in the company have chances to serve as the participants in this study. Data has been analysed from 148 respondents. Results: Results show significant and positive relationships between job performance, work-life balance and organizational justice towards employees' career satisfaction. Organizational justice is the most significant factor in career satisfaction in this study (β=.83, p=.00). Other factors such as job performance (β=.71, p=.00), and work-life balance (β=.71, p=.00) also positively correlated with employees’ career satisfaction. Implications/Applications: These significant results imply that managers should provide good elements of justice in the company to raise the level of their employee's career satisfaction. At the same time, the employees should maintain a higher level of job performance as well as to manage the good working life balance in them

Improved tool life in end milling Ti-6A1-4V through workpiece preheating

This paper presents the investigation of tool life improvement in end-milling of Titanium Alloy Ti-6Al-4V through workpiece preheating. End milling tests were conducted on Vertical Machining Centre with full immersion cutting. Induction heating was utilized during end milling for preheating. The titanium alloy Ti-6Al-4V bar was used as the workpiece. Machining was performed with a 20 mm diameter end-mill tool holder fitted with one PCD inserts. All of the experiments were run under room temperature and preheating condition at 315, 450, and 650ºC. Flank wear has been considered as the criterion for tool failure and the wear was measured using a Hisomet II Toolmaker’s microscope. Tests were conducted until an insert was rejected when an average flank wear greater than 0.30 mm was recorded. Cutting force and torque measurements were conducted using the Kistler Rotating Cutting Force Dynamometer. Vibration during cutting was captured using an online vibration monitoring system. Scanning electron microscope (SEM) was also used to investigate the wear morphology. The results led to conclusions that workpiece preheating significantly increases the tool life of PCD inserts in end-milling of Titanium Alloy Ti-6Al-4V

UNDERSTANDING THE EFFECTS OF INTERPERSONAL COMMUNICATION AND TASK DESIGN ON JOB PERFORMANCE AMONG EMPLOYEES IN THE MANUFACTURING COMPANY

on job performance among employees from the manufacturing industry. Methodology: The data is analyzed through a survey (questionnaire) from 152 employees in one of the manufacturing companies in Penang, Malaysia. Hypotheses for all direct effects between the predictors (eg. interpersonal communication and task design) and criterion (job performance) are tested using regression analysis.  Result: Results presented that employees in this company have a high level of job performance (µ = 3.70); interpersonal communication (µ =3.64) and task design (µ =3.66). Also, positive correlations are found between employees’ performance and interpersonal communication (r=.53, p=.00) and task design (r=.54, p=.00). Implications: Thus, this research provided a fruitful knowledge regarding the level of employees’ performance as well as their internal communication and task design; among employees in one of the manufacturing company in Malaysia

Nigella sativa meal alleviates injury against benzo[a]pyrene exposures in broilers

This study was conducted to evaluate the effects of Nigella sativa (Ns) meal on such influences of Benzo[a] Pyrene (BaP) on the broilers performance, pulmonary index (PI), and histopathological changes. Chicks were assigned into four equal groups, namely as controls, Ns, BaP and BaP with Ns. Six birds were sacrificed at days 7, 14, 21, and 35. The results revealed that there were significant decreases (p<0.05) in the mean body weight (BW) values and body weight gain (BWG) in the BaP alone group. Pulmonary weight (PW) and index increased (p<0.05) in the same group compared to the control groups. Pulmonary morphology showed heavy infiltration and denudation of ciliated epithelium in the trachea, with infiltration by polymorphonuclear and mononuclear cells in the parabronchi of the lung, in the BaP exposed chickens. Nigella sativa (Ns) supplementation significantly alleviated these alterations, and thereby showing a potent anti-inflammatory effect after 14 days in the treated group. A key finding from this study is that BaP triggers inflammatory disorders and this transient effect is believed to be fatal if an infection occurs warranting a reassessment of the health status on exposure, and Ns was found to be helpful in alleviating such effects in broiler chickens

KINEROS2 application for land use/cover change impact analysis at the Hulu Langat Basin, Malaysia

The impacts of land use/cover changes (LUCC) on a developed basin in Malaysia were evaluated. Three storm events in different intensities and durations were required for KINEROS2 (K2) calibration and LUCC impact analysis. K2 validation was performed using three other rainfall events. Calibration results showed excellent and very good fittings for runoff and sediment simulations based on the aggregated measure. Validation results demonstrated that the K2 is reliable for runoff modelling, while K2 application for sediment simulation was only valid for the period 1984-1997. LUCC impacts analysis revealed that direct runoff and sediment discharge increased with the progress of urban development and unmanaged agricultural activities. These observations were supported by the NDVI, landscape and hydrological trend analyses

The critical review of the pollution haven hypothesis (PHH)

This paper evaluates the theoretical and empirical basis of the Pollution Haven Hypothesis (PHH) and Porter Hypothesis. The PHH claims that owing to international trade and Foreign Direct Investment (FDI), the developing countries have become the pollution haven for the advanced countries. The Porter Hypothesis portraits an opposite picture than the PHH. According to, the Porter Hypothesis, the FDI in home country induce the induction of more advanced and clean technologies that lead to cleaner environment. In the literature, there is mixed support for these opposing hypotheses. This paper therefore, recommends further rigours research that aims at to find out the true link between trade, FDI and environmental degradation

Thermogravimetric study of Chlorella vulgaris for syngas production

The present study investigates the thermal degradation behavior of Chlorella vulgaris using a thermogravimetric analyzer (TGA) to explore application as feedstock for syngas production. The biomass was heated continuously from room temperature to 1000 °C at different heating rates (5, 10 and 20 °C min− 1) under N2/air conditions at a constant flow rate of 25 mL min− 1. Experimental results showed that the combustion process of C. vulgaris can be divided into three major phases; (1) moisture removal, (2) devolatilization of carbohydrates, protein and lipids and (3) degradation of carbonaceous material. A degradation rate of 80% was obtained at the second phase of the combustion process in the presence of air whilst a degradation rate of 60% was obtained under N2 atmosphere at the same phase. The biomass was further gasified for syngas production using a Temperature Programmed Gasifier (TPG). The effect of three different process variables, temperature, microalgal loading, and heating rate was investigated. The maximum H2 production was found at 800 °C temperature with a biomass loading of 0.5 g. No significant effect of heating rate was observed on H2 production. The activation energy values, based on the Kissinger method, were evaluated to be 45.38 ± 0.5 kJ mol− 1 (1st stage), 61.20 ± 0.5 kJ mol− 1 (2nd stage) and 97.22 ± 0.5 kJ mol− 1 (3rd stage). The results demonstrate a significant potential for the utilization of the microalgae biomass as feedstock for large-scale production of syngas via gasification
