The public relations industry as one of the key industries in Hong Kong has metamorphosed into a new phase after the resumption of sovereignty to China. Based on in-depth interviews with eight experienced corporate communication practitioners from multi-national and sizeable local corporations in Hong Kong and China, the study traces the recent development of public relations and/or corporate communication (hereafter PR/CC) highlighting issues of role and function, language and communication strategy, and ethics and professionalism.  相似文献

Mentoring programmes show significant promise for enhancing the well‐being of youth with complex needs. Research indicates that high quality mentoring, although difficult to achieve, positively impacts youth development across behavioural, social, emotional and academic domains. The difficulty of sustaining long‐term matches between mentors and youth, however, remains an important concern for the field of mentoring, as foreshortened matches can be harmful to youth. The 4Results mentoring programme has been identified as a Promising Practice through the Washington State Inventory of child‐serving behavioural and mental health programmes and has developed a unique infrastructure to support critical programme values such as match longevity. In 7 years, the programme has successfully retained 98% of mentors for at least 1 year with an average match length of 3.7 years. The following article describes the programme's guiding philosophy and approach to recruiting and training mentors in the context of existing best practices research.  相似文献

Over 880 communities have put regulations in place to reduce or eliminate tobacco use in buildings used by the public. This study examines the experience of one such community—Well City, Ohio. The nonsmoker protection efforts in Well City help us identify and discuss eight important considerations affecting policy development and implementation: (1) anticipate community opposition, (2) identify and collaborate with a support network, (3) control the community hearing process, (4) anticipate outside interests, (5) recognize the potential for legal challenges, (6) address life with legal limbo, (7) start strong, and (8) watch the mix of politics and public health. Current clean indoor air efforts seem to focus on establishing coalitions and encouraging employers to voluntarily establish tobacco-free workplaces and restaurants. These efforts certainly need to continue but as a basic part of a comprehensive program which recognizes the importance and fosters the development of strong nonsmoker protection regulations developed at the local level by health boards, county boards of supervisors, and/or city councils.  相似文献

An essential facet of a risk assessment is the correct evaluation of uncertainties inherent in the numerical results. If the calculation is based on an explicit algebraic expression, an analytical treatment of error propagation is possible, usually as an approximation valid for small errors. In many instances, however, the errors are large and uncertain. It is the purpose of this paper to demonstrate that despite large errors, an analytical treatment is possible in many instances. These cases can be identified by an analysis of the algebraic structure and a detailed examination of the errors in input parameters and mathematical models. From a general formula, explicit formulas for some simple algebraic structures that occur often in risk assessments are derived and applied to practical problems.  相似文献

Under the communist regime, the Chinese government has developed policies both to limit the growth of large cities and to promote spatial equity in population distribution. The literature provides only very general and inconclusive results regarding the impact of these policies. This paper aims at evaluating the effectiveness of China's urban policies by investigating the temporal and spatial dynamics of the size distribution of China's cities during the period 1922–82. The research framework — which is based on a function relating population size to rank —is used to test for trends of deconcentration (where smaller cities grow faster than larger cities) and spatial decentralization (with a more even spatial distribution) of population over the study period. More formally, the ‘expansion methodology’ is used to investigate the dynamics of the rank-size function in both temporal and spatial dimensions. The findings show that from 1953 to 1970 there was significant population deconcentration, which appeared to be reversed subsequently. However, policies of spatial decentralization were not found to be successful. Among the reasons suggested for the apparent failure are political upheavals and shifts in policies, the inertia within the urban system, the harsh physical environment in the interior, and current trends in economic policies that focus on the coastal areas. In spite of recent criticisms of studies on city-size distributions (which this paper also discusses), the research framework proposed and utilized here is able to portray the dynamics of a national urban system, and the framework can be used to evaluate national urban policies.  相似文献

Abstract

In July 2004, Cindy Hepfer asked friends and colleagues: “What question would you like to ask Clifford Lynch if you had the chance?” As a result, Clifford Lynch discusses a wide variety of topics and issues impacting the serials community from Open Access, institutional repositories, what we can learn from Google and Amazon, and Shibboleth to where his favorite places are to travel and how he prepares for presentations.  相似文献
