This study examines the effects of Corporate SocialResponsibility (CSR) activity as a business strategy towards creating value for the company. Using the annual reports of 242 Malaysian listed companies, this study investigates the effects of CSR disclosure and firm performance in 2006 and 2008. This study also examines the interaction effects of ownership structure on this relationship. Results of this study provide evidence that CSR activity has the propensity to impact significantly on a company's success. The insignificant results reported in relation to the interaction effects of family and government ownerships further corroborate the strategic importance of CSR activities and disclosure decisions by managers in Malaysia. Overall, findings in this study indicate that CSR activities can potentially lead to strong financial performance. In addition, it also provides regulatory bodies with enhanced understanding in their efforts to improve CSR activities and disclosures even in agency setting characterised with the existence of dominant owners.
Objectives: To evaluate the quality of bitewing radiograph taken by Universiti Teknologi MARA (UiTM) dental students during daily clinical practices and to evaluate the difference in caries lesions found on bitewing radiographs and clinical examination. Materials and method: 120 patients who attended the undergraduate dental clinic for dental examination were included in this study. The inclusion criteria were patients within the age range of 17-45 years old, possessing at least three sets of posterior teeth, with bitewing radiographs taken by undergraduate dental students. The number of caries lesions detected by clinical examination, bitewing radiographs, and a combination of both methods were recorded. The quality of 240 bitewing radiographs was classified into three categories; excellent, acceptable, and unacceptable. The frequency of radiographic errors; foreshortening/elongation, horizontal overlapping, inadequate film coverage, non-ideal centering and inadequate contrast and density were also evaluated. Results: The quality of bitewing radiographs are mostly accepted to be used as a diagnostic tool and one of the factors which commonly affected the quality of the bitewing is the overlapping of adjacent teeth. The highest number of caries lesions were detected radiographically (74%) compared with 25% caries by clinical examination. The majority of radiographs (71%, n=171) were deemed to be of acceptable quality, 39(16%) were excellent, and 30(13%) were diagnostically unacceptable. “Horizontal overlap” was the most common error detected on the radiographs (n=139, 57.9%), followed by “non-ideal centering” (n=93, 38.8%), “inadequate contrast” (n=46, 19.2%) and “inadequate film coverage” (n=24,10%). The highest number of caries lesions were detected radiographically (74%) compared with 25% caries by clinical examination. Conclusion: The quality of the majority of bitewing radiographs taken by undergraduate dental students in this institution is acceptable. However, given that more than half of the radiographs possessed horizontal overlapping error, caries diagnosis may have been underestimated. Further training and periodic audits are required to reduce the percentage of errors in bitewing radiographs amongst undergraduate dental students.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
