A compelling communication tool that can potentially impact health‐related outcomes and indicators across numerous health problems among a diversity of audiences is the health communication campaign. The purpose of the current article is to discuss trends in the research and practice of health communication campaigns. First, we discuss the issue of campaign effects and discuss a framework that encompasses key principles of effective campaigns. Next, we discuss four trends in health communication campaigns: (a) the increased application of marketing principles in campaigns; (b) the greater use of rigorous outcome evaluation designs in campaign research; (c) the increased use of cost effectiveness analysis in campaigns; and (d) the increased use of new media technologies in campaigns. Finally, we conclude the article with thoughts about the future of health communication campaign research and practice in relation to these trends.  相似文献

We model nicotine from environmental tobacco smoke (ETS) in office air and salivary cotinine in nonsmoking U.S. workers. We estimate that: an average salivary cotinine level of 0.4 ng/ml corresponds to an increased lifetime mortality risk of 1/1000 for lung cancer, and 1/100 for heart disease; >95% of ETS-exposed office workers exceed OSHA's significant risk level for heart disease mortality, and 60% exceed significant risk for lung cancer mortality; 4000 heart disease deaths and 400 lung cancer deaths occur annually among office workers from passive smoking in the workplace, at the current 28% prevalence of unrestricted smoking in the office workplace.  相似文献

Members of an HIV-prevention research network were asked to describe ethical challenges faced in their work. Major themes included acceptable standards of care for participants, defining research of relevance to host countries, reducing risks related to stigma, designing research that meets local needs without contributing to an inadequate status quo, and ensuring informed consent for complex research with potentially vulnerable participants. The challenges are interrelated and highlight the need for innovative, practical strategies to be incorporated into the planning, design, and conduct of HIV prevention trials. Research in applied ethics to support decision-making about HIV prevention research is needed, along with ethics training, mechanisms to support community-wide benefit from research, and expanded dialog on ethics surrounding HIV prevention and public health research.  相似文献

Some of the special agendas and initiatives of the International Year of the Family (IYF), sponsored by the United Nations, are highlighted. After reviewing the history and structure of IYF, findings concerning salient areas and topics for nationally based policy and programs are presented. These findings are derived from a content analysis of materials assembled from 136 UN Member States, as well as analysis of other documents and discussions with the IYF Secretariat. The saliency of concerns is also presented by grouping countries according to their level of human suffering. Familycentric policy considerations are discussed, and implications are cited for universities, policy makers, and practitioners.  相似文献

Solving the problem of the adverse impact of human numbers on the natural environment is a collective action problem and, if we are to understand it fully, we need good interdisciplinary research which includes work by demographers and sociologists. A number of factors inhibit this work in Australia: narrow disciplinary training; the scarcity of extrinsic rewards; and, as population growth has come to depend on immigration, the risk of peer disapproval. There is also little encouragement for such research from political leaders or the public. Indeed survey data show that the more Australians worry about the state of the environment the more likely they are to want a higher migrant intake.  相似文献

This article reviews the post-Second World War literature on explanations for Australia’s immigration program. It discovers three main schools of thought based on net pull factors: the official explanation and two unofficial explanations which focus on migrants as workers and on migrants as consumers. However the growing importance of net push factors after 1974 means that some of this work is less relevant today. Explanations focusing on net push factors have yet to cohere into a distinct perspective (or perspectives) but some research has been done on chain migration and family-based migration strategies, asylum seekers, temporary movement, and migration and the law. Immigration research is sometimes controversial and politicized. While intellectual integrity must always take priority, the values of civility and tolerance are also important.  相似文献

Effective methods of birth control became more available in Victoria between 1971 and 1975. The possible effects of this on unplanned and unwanted fertility should be taken into account in explanations of the general decline in fertility of the period. However, all methods did not become more available for all people. Unmarried people, poorer people, and migrants were disadvantaged, especially in so far as contraception was concerned. Continuing problems in gaining access to suitable methods of contraception may help to explain a persistence of unwanted fertility, either aborted or carried to term.  相似文献
