- PublicationCorporate investment inefficiency of Chinese firms: The roles of government subsidies, political connections and ESG performance(2024-03)This study aims to investigate the impact of government subsidies and political connections on corporate investment inefficiency in overinvestment and underinvestment scenarios, as well as the moderating role of ESG performance on the relationship between government subsidies, political connections and investment inefficiency in China, using an unbalanced panel dataset of 29,596 firm-year observation of Chinese listed firms for the period 2011-2021.
- PublicationMarket Sentiment And Housing Prices And Policies In Hong Kong High-Rise Residential Properties(2023-07)With skyrocketing prices and rapid episodes of economic booms and busts, standard financial theories could not explain the housing market behaviour in Hong Kong. The significant gap between the explanation of market fundamentals and the actual housing prices, leading to inappropriate predictions and misleading policy implications. This study is divided into two parts: an econometric analysis of the situation and a policy analysis with recommendations.
- PublicationCeos Early Life Experience And Corporate Social Responsibility: Evidence From Listed Companies In China(2024-02)Using a sample of 6,008 firm-years observations on public listed companies in China from year 2010 to 2019, this study examines the impact of CEO’s early life experiences on firms’ CSR taking. The regression results show that CEO’s early life experiences have a significant influence on firm’s CSR taking.
- PublicationThe Role Of National Museums Of China In Chinese History In The Post Mao Zedong Era, 1976-2011(2024-02)This study aims to examine the role of the National Museum of China (henceforth CNM) in the development of China's historical process in the post-Mao era (1976-2011), when China's unprecedented Cultural Revolution took place in 1966, putting traditional Chinese culture with a history of more than 5,000 years in jeopardy.
- PublicationCharacterization Of Aerophytic Oxyphototrophs Isolated From Gua Tempurung, Malaysia: Polyphasic And Biochemical Approaches(2024-03)Caves are among the extreme oligotrophic environments with limited nutrients and low light intensity, but some aerophytic microalgae find this environment suitable for their growth and survival. Gua Tempurung is the largest limestone caves in Malaysia, but unfortunately no study was conducted on its algal diversity, taxonomic information, adaptation, physiological, and biochemical composition. This study aimed to assess the characteristics and adaptation of aerophytic oxyphototrophs isolated from Gua Tempurung.

- PublicationThe prevalence of obesity and its associated factors among nursing students in Universiti Sains Malaysia(2023-06)Obesity according to WHO (2021) is refers to Body Mass Index (BMI) greater than or equal to 30 kg/m². Obese people are at risk for many negative effects relating to health. Obesity has grown to epidemic proportions, with over 4 million people dying each year as a result of being obese in 2017, that caused a chronic health condition. This study aims to assess the prevalence of obesity, its association with physical activity, stress, eating behavior and selected socio-demographic factors among nursing students in USM. A cross-sectional survey was done using a set of self-administered questionnaires that contained questions from the IPAQ, PSS-10 and Eating Behavior scales. A total of 207 nursing students from Diploma and Bachelor programmes participated in this study. Data were analyzed by using SPSS version 27.0. The findings indicated that a total 24 (11.6%) nursing students had obesity. Most of the participants had moderate physical activity (45.4%), moderate stress (82.6%) and good eating behavior (20.7%). There is no significant association between obesity with physical activity (p=0.987), stress (p=0.970) and eating behavior (p=0.665). In terms of socio-demographic factors, a significant association was only indicated in age (p=0.048) and gender (p=0.048). In conclusion, although the prevalence of obesity is considered lower among nursing students in USM, appropriate and continuous initiative need to be done by the authorities to raise young people’s awareness on the bad impact of obesity and encourage them to keep practicing healthy life style.
- PublicationEffect Of Stand-Off Distance And Plasma Current On The Properties Of Hydroxyapatite Coatings Produced By Plasma Spray(2014-12)Plasma sprayed hydroxyapatite (HA) coatings on metallic implants for biomedical applications are attracted significant researchers interest due to accelerated rate of bone bonding that occurs following their implantation. This present work aims to produce plasma sprayed HA coatings with varying spray parameters (i.e.; stand-off distance, SOD and plasma current, PC) in order to control the coatings crystallinity. The substrate used is 316L stainless steel. Five SODs were selected i.e. 80 mm, 100 mm, 120 mm, 140 mm and 160 mm combined with two different PCs (500 A and 600 A), respectively. The coatings then divided into two groups (as sprayed and heat treated). Both coating was subjected to in vitro test through immersion in SBF solution up to 28 days to determine their bioactivity. The coating properties before and after immersion in SBF were analyzed using FESEM and XRD. The analysis showed coatings morphology consists of type III, V and VIII splats with lamella and non-lamella structures. The crystallinity of as-sprayed coatings is in vicinity of 50%. However, the crystallinity increases more than 90% after heat treatment process. The in vitro analysis proved that the highest apatite layer precipitations on surface with coatings surface was from the assprayed coatings rather than the one being heat treated. Therefore, the quality of HA coating via plasma spray coating technique can be modified through the suitable combination is at SOD 120 mm and PC 600 A.
- PublicationMineralogical alteration and paragenesis of gold mineralization in Air Piau deposit, Kelantan, Peninsular Malaysia(2025-08-04)The Air Piau deposit in Kelantan, situated within Malaysia’s Central Gold Belt, hosts significant gold mineralization associated with mesothermal quartz veins in deformed metasedimentary rocks, yet its mineralogical alteration and paragenesis remained poorly characterized compared to other regional deposits. This research aimed to investigate the mineralogical alteration and paragenesis gold mineralization at the Air Piau deposit. The study combined detailed petrography, ore microscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and Atomic Absorption Spectroscopy (AAS). Laboratory preparation of thin and polished sections for mineralogical characterization. The results revealed that gold mineralization is spatially associated with quartz-carbonate veins hosted in greenschist (Chl+Bt+Qz) to lower amphibolite facies metasediments. Hydrothermal alteration zones(propyllitic and argillic), were found to correlate strongly with elevated gold concentrations. The highest gold content recorded was 0.93 ppm, with corresponding high values of arsenic (137 ppm) and lead (100 ppm). Paragenetic analysis indicated multiple stages of mineral deposition influenced by regional tectonics and magmatic-hydrothermal processes. This study provides the comprehensive mineralogical alteration of the Air Piau gold deposit to refine exploration models and guide more effective targeting of mineralized zones in Central Gold Belt, Malaysia.
