    The paper examines the impacts of financial development on sectoral carbon emissions (CO2) for environmental quality in Malaysia. Since the financial sector is considered as one of the sectors that will contribute to Malaysian economy to become a developed country by 2020, we utilize a cointegration method to investigate how financial development affects sectoral CO2 emissions. The long-run results reveal that financial development increases CO2 emissions from the transportation and oil and gas sector and reduces CO2 emissions from manufacturing and construction sectors. However, the elasticity of financial development is not significant in explaining CO2 emissions from the agricultural sector. The results for short-run elasticities were also consistent with the long-run results. We conclude that generally, financial development increases CO2 emissions and reduces environmental quality in Malaysia.

    Regional estimates of VOC fluxes focus largely on emissions from the canopy and omit potential contributions from the forest floor including soil, litter and understorey vegetation. Here, we measured monoterpene emissions every 2 months over 2 years from logged tropical forest and oil palm plantation floor in Malaysian Borneo using static flux chambers. The main emitted monoterpenes were α-pinene, β-pinene and d-limonene. The amount of litter present was the strongest indicator for higher monoterpene fluxes. Mean α-pinene fluxes were around 2.5-3.5 μg C m-2 h-1 from the forest floor with occasional fluxes exceeding 100 μg C m-2 h-1. Fluxes from the oil palm plantation, where hardly any litter was present, were lower (on average 0.5-2.9 μg C m-2 h-1) and only higher when litter was present. All other measured monoterpenes were emitted at lower rates. No seasonal trends could be identified for all monoterpenes and mean fluxes from both forest and plantation floor were ~ 100 times smaller than canopy emission rates reported in the literature. Occasional spikes of higher emissions from the forest floor, however, warrant further investigation in terms of underlying processes and their contribution to regional scale atmospheric fluxes.

    Consistent with the worldwide call to combat environmental degradation concerns and advance sustainable development, there is increasing pressure on organizations to ensure organizational strategies include green initiatives. In this regard, environmental strategic focus is a relevant concept for scholars and business leaders. Underpinned by dynamic capability and stakeholder theory, the present study hypothesizes that ESF derives environmental performance, coordinated by mediating role of green shared vision that strategic environmental planning and decision making. Additionally, the current study employed ISO 14001 and technological capability as moderators between ESF and the green shared vision link. Methodologically, the data for this study was collected from 162 senior managerial officials working in EMS 14,001-accredited manufacturing firms in Malaysia. The data were analyzed with the AMOS 23 software to perform covariance-based structural equation modeling (CB-SEM), and then hierarchical regression analysis and moderated-mediation analysis were applied with SPSS 25. The findings confirmed that ESF is positively linked to environmental performance. The results validate that green shared vision acts as a positive mediator between ESF and environmental performance, in which the creation and sharing of knowledge embedded in a green shared vision serve as enablers to create higher environmental performance. The current study also validates a significant moderating role of ISO 14001 and technological capability between ESF and green shared vision. The study confirms how environmental strategies are integrated into environmental management processes that can serve as a source of dynamic capabilities.

    Morphological processing in visual word recognition has been extensively studied in a few languages, but other languages with interesting morphological systems have received little attention. Here, we examined Malay, an Austronesian language that is agglutinative. Agglutinative languages typically have a large number of morphemes per word. Our primary aim was to facilitate research on morphological processing in Malay by augmenting the Malay Lexicon Project (a database containing lexical information for almost 10,000 words) to include a breakdown of the words into morphemes as well as morphological properties for those morphemes. A secondary goal was to determine which morphological variables influence Malay word recognition. We collected lexical decision data for Malay words that had one prefix and one suffix, and first examined the predictive power of 15 morphological and four lexical variables on response times (RT). Of these variables, two lexical and three morphological variables emerged as strong predictors of RT. In GAMM models, we found a facilitatory effect of root family size, and inhibitory effects of prefix length and prefix percentage of more frequent words (PFMF) on RT. Next, we explored the interactions between overall word frequency and several of these predictors. Of particular interest, there was a significant word frequency by root family size interaction in which the effect of root family size is stronger for low-frequency words. We hope that this initial work on morphological processing in Malay inspires further research in this and other understudied languages, with the goal of developing a universal theory of morphological processing.

    OBJECTIVES: Suffering is common among patients with advanced cancer. The practice of mindfulness during patient care can potentially reduce suffering. We aimed to examine the efficacy of mindfulness-based supportive therapy (MBST) on reducing suffering in patients with advanced cancer.

    METHODS: We conducted a parallel-group, single-blinded, randomised controlled trial at the University of Malaya Medical Centre, Malaysia. Seventy-three patients with advanced cancer with an overall suffering score ≥4/10 based on the Suffering Pictogram were recruited and randomly assigned into either the MBST group (n=34) or the control group (n=39).

    RESULTS: There was a statistically significant reduction in the overall suffering score in the MBST group compared with the control group (U=432.5, median1=-2.0, median2=-1.0, z=-2.645, p=0.008). There was also significant improvement in the total Hospital Anxiety and Depression Scale score (U=483.5, median1=-4.0, median2=-3.0, z=-1.994, p=0.046), and the total Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being score (U=252.0, median1=+14.5, median2=+5.0, z=-4.549, p=0.000) in the MBST group compared with the control group.

    CONCLUSIONS: The results provided evidence that the practice of MBST during patient care could promote positive psychosocial outcomes.

    COVID-19 infection resulted in significant economic implications to patients as well as a considerable financial burden to the general population for preventive measures. A descriptive study was conducted among staff at one of the public universities in Malaysia to estimate the monthly out-of-pocket expenditures for preventive measures used for COVID-19 infection. The study tool includes questions on household out-of-pocket expenditure and the measurements of the impact of the expenditure on household income. It was found that the average cumulative monthly expenditures related to the preventive measures were US$ 45.90 (Ringgit Malaysia 187.77), which was 4.3% of the household income. The highest expenditures were for traditional and complementary medicine followed by nutraceutical/supplements and disposable facemask. 8% of the households in this study incurred more than ten per cents of their monthly household income for expenditures related to COVID-19 preventive measures. Several households are experiencing substantial financial implications for preventive measures related to COVID-19 infection. This study highlights the out-of-pocket expenditures incurred for preventive measures were substantial for certain households. Effective initiatives from the government on providing subsidized protective personal equipment and a cost-sharing approach could help to alleviate the household financial burden.

    This study investigates the effects of the Russia-Ukraine conflict on the quality and quantity of Malaysia's palm oil production through a time series analysis. The study uses three primary factors to evaluate palm oil production: the Monthly Oil Extraction Rate (OER), the Monthly Fresh Fruit Bunch (FFB) Yield, and the Monthly Oil Exports. The results indicate that the Russia-Ukraine conflict significantly impacted the quality and quantity of palm oil production in Malaysia. Marginal declines in both the quality and quantity of palm oil produced at the onset of the conflict indicate a slight but significant decline in palm oil production during the next four-year period.

    Air pollution events can be categorized as extreme or non-extreme on the basis of their magnitude of severity. High-risk extreme air pollution events will exert a disastrous effect on the environment. Therefore, public health and policy-making authorities must be able to determine the characteristics of these events. This study proposes a probabilistic machine learning technique for predicting the classification of extreme and non-extreme events on the basis of data features to address the above issue. The use of the naïve Bayes model in the prediction of air pollution classes is proposed to leverage its simplicity as well as high accuracy and efficiency. A case study was conducted on the air pollution index data of Klang, Malaysia, for the period of January 01, 1997, to August 31, 2020. The trained naïve Bayes model achieves high accuracy, sensitivity, and specificity on the training and test datasets. Therefore, the naïve Bayes model can be easily applied in air pollution analysis while providing a promising solution for the accurate and efficient prediction of extreme or non-extreme air pollution events. The findings of this study provide reliable information to public authorities for monitoring and managing sustainable air quality over time.

    Surface sediments along the Southern Terengganu coast (≤7 km from the coast) were analyzed for polycyclic aromatic hydrocarbons (PAHs). The concentrations of 16 USEPA priority polycyclic aromatic hydrocarbons (ΣPAH16) ranged from 2.59 to 155 ng g-1 and their respective alkylated ranged between 8.80 and 24.90 ng g-1. Traces of acephenanthrylene, benzo[c]phenanthrene, thiophenic PAH, and benzonaphthofuran were identified. PAH diagnostic ratios and cross-plots revealed that these sedimentary PAH compounds are derived mainly from pyrogenic sources, primarily from biomass burning and petroleum combustion residues with minor petrogenic input. The high correlations between pyrogenic PAHs to total PAHs (r >0.73, p <0.5), and the Bap/Bep ratio to total PAHs (r = 0.88, p <0.5), suggest that atmospheric deposition and urban runoff are the main deposition pathways. The concentrations of the PAHs in the southern South China Sea fall in the moderate contamination range of 100-1000 ng g-1.

    Residual oil from palm oil mill effluent (POME) can be valorized into value-added products like biofuel. However, the complex structure in POME limits the full recovery of intracellular lipids. To address this challenge, low-frequency ultrasonication was used as a pre-treatment prior to oil recovery to improve the yield by liberating the entrapped oil via the cell disruption technique. This study focused on optimizing the ultrasound conditions (i.e., ultrasonication amplitude, ultrasonication duration, and probe immersion depth) to maximize the improvement of oil recovery yield using response surface methodology. The optimized conditions were 30.074% ultrasonication amplitude, 0.167 min ultrasonication duration, and 2 cm probe immersion depth. This resulted in an additional 42.50% improvement in oil recovery yield over non-ultrasonicated POME, which is in close agreement with the model prediction. Additionally, a cost-benefit analysis was incorporated to determine the feasibility of ultrasonication for enhancing oil recovery. The study also explored the synthesis of biodiesel from POME-recovered oil and characterized the fuel attributes according to American Society for Testing and Materials- and European Standards-prescribed procedures. The attributes of biodiesel produced from POME-recovered oil are comparable to those of palm-based biodiesel in Malaysia, demonstrating its potential as an alternative source for biodiesel production.

    Recent collection in Panti Forest Reserve in Johor, Peninsular Malaysia offered us the opportunity to better understand the species in southern Malay Peninsula. Two new species and one new genus of Meconematini are described here: Cercoteratura reflexa sp. n. and Platycercotura caricauda gen. et sp. n. We present new locality records for Peracca macritchiensis Tan & Ingrisch, 2014, Viriacca viridis Ingrisch, 1998; Lipotactes (Dialipotactes) maculatus Hebard, 1922; Asiophlugis rete Gorochov, 1998; and Arnobia pilipes tropica Gorochov, 1998, all of which were previously recorded in Pahang (Peninsular Malaysia) and Singapore, suggest that the distribution of these species is continuous between Pahang and Singapore. New locality record for Asiophlugis temasek temasek Gorochov & Tan, 2011, previously known only from Singapore, indicates that this subspecies is no longer endemic to Singapore.

    Background: The confidence of Bottom 40 (B40) shareholders is crucial for cooperative's sustenance within wider corporate governance. An in-depth study on cooperatives is needed, as they play a crucial role in the Malaysian economic system and contribute greatly to the country's social development. However, in the current landscape, confidence among shareholders is at stake. This study aims to identify the research gap into corporate governance for cooperativess in relation to B40 shareholder confidence, as well as identify current study challenges and develop a conceptual framework for future research. Methods: We conducted a systematic literature review, with the use of agency theory to assess shareholders' confidence. Emerald, ProQuest, InderScience, Scopus and Science Direct were the online databases used in this study to search five keyword phrases: corporate governance, confidence, cooperative, agency theory and Bottom 40% (B40) household. Tranfield's five stages were used to conduct the systematic review. Results: Only 5 of the 324 studies assess shareholders' confidence in cooperatives, as well as one paper on B40 and two papers on agency theory. Our review presents three major findings. First, research in the context of B40 shareholder's confidence in cooperatives is scarce. Second, the challenges related to shareholders' confidence in B40 are major issues in the context. Third, research on agency theory in the context of shareholders' confidence within cooperatives and corporate governance is still scant. Conclusions: This review urges the research community to conduct more studies based on the highlighted research gaps.

    INTRODUCTION: Given the stagnating progress in the fight against dengue in Kota Kinabalu, there is an urgent need to use other strategies to complement the existing vector control, focusing on larviciding. Unmanned aerial vehicle (UAV) technology has been used in vector control programs in many countries. The aim of this study was to determine the feasibility of using UAVs for larviciding to control Aedes mosquitoes in urban areas.

    METHODOLOGY: The Hexarotor Agro Drone (Polardrone Sdn Bhd, Malaysia) was used to carry out larviciding using Vectobac® manufactured by Valent BioSciences LLC, Libertyville, USA. The drone flew at a height of 10 feet and at a speed of 5 m/s. A total of 32 items with 10 larvae in each item were placed to test the effectiveness of larviciding using UAV.

    RESULTS: Out of 32 items used, 4 containers had a 100% larva mortality (13.3% mortality). The drone was not able to reach the designated spraying route that had been pre-programmed. This was due to interference with the electromagnetic waves emitted from the home satellite dishes, that were in front of the houses along the route.

    CONCLUSIONS: This trial showed that UAVs will be more suitable for use in larviciding in an open area without electromagnetic disturbances from electric house poles and satellite TV dishes that are commonly present in urban areas.

    This study contributes to the existing body of research by examining the mediating effect of ethics in the relationship between mathematics teacher cooperation and readiness. It fills a gap in the literature by investigating the ethical dimensions of collaboration and their impact on readiness for the industrial revolution. This study aims to determine the mediator effect of ethics between the relationship of Mathematics Teacher Cooperation and Readiness in Facing the Era of Industrial Revolution. The study involved a total of 231 mathematics teachers in Indonesia and a total of 384 mathematics teachers in Malaysia using simple random sampling. A survey was conducted to determine the readiness of mathematics teachers in facing the industrial revolution. This study used SEM analysis (using AMOS software) to determine the model of teacher readiness facing the era of industrial revolution such as the direct effect of mathematics teacher cooperation and readiness in facing the era of industrial revolution, the essence of ethics as mediators of the relationship between mathematics teacher cooperation and readiness in facing the era of industrial revolution. The study findings showed collaboration has significant effect on IR4.0 readiness and the direct effect of collaboration on ethics was also significant. Indirectly, ethics has a significant mediating effect in the contribution between collaboration on the readiness of IR4.0 among mathematics teachers in Indonesia and Malaysia. A partial mediator occurred in the results of this study. In conclusion, the study's implications and recommendations emphasize the importance of collaborative practices, ethics, and cross-cultural considerations in preparing mathematics teachers for the Industrial Revolution era in Indonesia and Malaysia. These recommendations highlight the significance of policy support, professional development, ethical guidelines, and research-informed practices to enhance readiness for the challenges brought about by technological advancements.
