Stock Market Liberalisation And Cost Of Equity: Firm-Level Evidence From Malaysia

This study extends the stock market liberalisation literature by conducting a firm-level analysis on the emerging economy of Malaysia. Using a finer measure of foreign ownership, we explore the association between liberalisation and cost of equity for public listed firms on Bursa Malaysia over the sample period of 2002-2009. We find strong support for our hypothesis that total foreign ownership is negatively and significantly associated with cost of equity. Further disaggregate analysis suggests foreign institutions that trade through direct accounts are driving the lower cost of equity. When the model is extended to include interaction term, we find that an effective board of directors further strengthens the negative relationship between foreign institutions and cost of equity. Our empirical results consistently support the corporate governance channel in which foreign institutions play an active monitoring role

As implied by the title, this final year project explores the business environment in Vietnam. We will study the opportunities and threats from the stand point of a typical cautious Singaporean businessman. We will also look into the various major industries in Vietnam.BUSINES

Public Hospital Pharmacists’ Perceptions and Knowledge of Antibiotic Use and Resistance: A Multicenter Survey

Antimicrobial Stewardship Program (ASP) has been implemented in major public hospitals in Malaysia, with pharmacists playing a key role in ensuring the appropriate use of antibiotics. This survey aimed to assess the practices, perceptions, and knowledge of public hospital pharmacists on antibiotic use and resistance. A cross-sectional survey involving pharmacists from six public hospitals in Penang was conducted using a self-administered validated questionnaire. The majority of pharmacists perceived that polypharmacy (92%, n = 270) and overuse of broad-spectrum antibiotics (85%, n = 252) can potentially induce resistance of microorganisms and that ensuring the rational use of antibiotics is a shared responsibility between clinicians and pharmacists (94%, n = 278). A large majority of the pharmacists think that formal training in infectious disease should be a pre-requisite for pharmacists in ASP (93%, n = 273). In terms of antibiotic selection, the availability of antibiotics in hospital (81%, n = 234) and patient’s clinical condition (68%, n = 196) are more of a concern to the pharmacists. A total of 65% of the respondents (n = 192) demonstrated good levels of knowledge with a mean knowledge score of 10.1 out of 13 (95% CI: 9.95; 10.31). Pharmacists from the managerial level, ward pharmacy, in-patient, and medication therapy adherence clinic (MTAC) unit had better knowledge of antibiotics compared to pharmacists from other units (p < 0.001). Antibiotic knowledge gap had been identified among pharmacists in different work settings, and longer years of service does not warrant good antibiotic knowledge

Impact of body mass index on perioperative outcomes of laparoscopic major hepatectomies

Background: Data on the effect of body mass index on laparoscopic liver resections are conflicting. We performed this study to investigate the association between body mass index and postoperative outcomes after laparoscopic major hepatectomies. Methods: This is a retrospective review of 4,348 laparoscopic major hepatectomies at 58 centers between 2005 and 2021, of which 3,383 met the study inclusion criteria. Concomitant major operations, vascular resections, and previous liver resections were excluded. Associations between body mass index and perioperative outcomes were analyzed using restricted cubic splines. Modeled effect sizes were visually rendered and summarized. Results: A total of 1,810 patients (53.5%) had normal weight, whereas 1,057 (31.2%) were overweight and 392 (11.6%) were obese. One hundred and twenty-four patients (3.6%) were underweight. Most perioperative outcomes showed a linear worsening trend with increasing body mass index. There was a statistically significant increase in open conversion rate (16.3%, 10.8%, 9.2%, and 5.6%, P < .001), longer operation time (320 vs 305 vs 300 and 266 minutes, P < .001), increasing blood loss (300 vs 300 vs 295 vs 250 mL, P = .022), and higher postoperative morbidity (33.4% vs 26.3% vs 25.0% vs 25.0%, P = .009) in obese, overweight, normal weight, and underweight patients, respectively (P < .001). However, postoperative major morbidity demonstrated a "U"-shaped association with body mass index, whereby the highest major morbidity rates were observed in underweight and obese patients. Conclusion: Laparoscopic major hepatectomy was associated with poorer outcomes with increasing body mass index for most perioperative outcome measures
