Survival of methicillin-resistant staphylococcus aureus on toothbrushes stored under protective covers and sanitizers
No full textObjective: To investigate the survival of methicillin-resistant Staphylococcus aureus on toothbrushes stored under commercially available antimicrobial and non-antimicrobial covers. Methods: Standardized inocula of methicillin-resistant Staphylococcus aureus (MRSA) ATCC 700698 were prepared and adjusted to a 0.5 McFarland standard (approximately 1.5x108 cfu/mL). A total of 45 toothbrush heads were contaminated with MRSA by submerging in 5mL of bacterial culture and vortexing for three minutes. Toothbrush heads were then stored for 24 hours under a thymol vapor-emitting toothbrush cover (Steripod), standard plastic cover with ventilation holes (Coghlan’s), moisture-absorbent cover (IntelliDent Toothbrush Shield), or ultraviolet light sanitizer (Docooler). Toothbrush heads were vortexed for 15s in 5mL of sterile 0.9% sodium chloride solution, and serial dilutions were performed prior to spiral plating on blood agar. The positive control consisted of immediately vortexing to remove bacteria following contamination with the inoculum. Colony-forming units (cfu) were enumerated after overnight aerobic incubation at 37oC. All assays were performed in triplicate. Results: Significant reductions (p Conclusion: Survival of MRSA was significantly lowered on toothbrushes stored under the thymol vapor-emitting cover, moisture-absorbent cover, and UV sanitizer. None of the toothbrush covers was able to completely eradicate MRSA following a storage period of 24 hours

Exploring policy options to combat illegal micro-apartments in Hong Kong
No full textIllegal building can take multiple forms, including squatter settlements and illegal building extensions. Among the various forms of illegal building, illegal microapartments (IMAs), which take the form of unauthorised subdivided housing units, have recently aroused wide public concern in Hong Kong. On account of their unlawful nature, IMAs pose serious threats to the safety of local communities by undermining structural stability and fire safety in buildings. They may also adversely affect natural lighting and ventilation for building occupants. Fatal fires in buildings with IMAs in recent years have demonstrated the painful consequence of ignoring this issue in the city. Nonetheless, the problem of IMAs has seldom attracted scholarly attention around the world. In light of the seriousness of the IMA problem in Hong Kong, this study explores workable policy options for cracking down on the problem. It reviews policies or proposals in different jurisdictions to crack down on IMAs. Then a threeround policy Delphi study is carried out with a panel of stakeholders to identify and prioritise policy options for combating IMAs in Hong Kong. Various measures are proposed or identified by the panel members, ranging from increasing the frequency of building inspections and imposing stricter penalties on non-conforming owners to licensing IMAs for private renting. Among these options, stricter enforcement is considered the most workable option. The results of the policy Delphi study are discussed and policy recommendations are made
Practices of Corporate Social Responsibility in China and Hong Kong
No full textChina and Hong Kong have a long history of practicing corporate giving and caring, guided by the deeply ingrained pursuit of the collective good. This chapter begins with a brief description of the historical and philosophical roots of corporate social responsibility in the Chinese context. Differences in the political system and economic development have shaped the courses that China and Hong Kong tread in practicing corporate social responsibility (CSR). In recent decades, CSR in China has been driven by government initiatives and the introduction of mandatory environmental and social responsibility reporting. It is also more visible among large-scale corporations. CSR in Hong Kong is more likely to be driven by company initiatives assuming a bottom-up approach among large corporations, as well as by small and medium-sized enterprises. The chapter goes on to discuss public perceptions of CSR. It ends with two case studies of CSR practices, one a negative example, and the other positive
