ABSTRACTMedia have multipronged linkages to violence, and these have been studied in considerable detail in the fields of communication and media studies. With commercialisation of media and the rapid decline of paying subscribers, for their survival in a capitalist economy, media have to rely increasingly on advertising revenues, and on other ways of linking to markets. Portrayals of violence have become reliable vehicles for ensuring media profitability – in terms of generating advertising revenue – as well as for generating revenue streams via related market-developing and market-maintaining ways. With the advent of new media – social media, virtual reality media and Artificial Intelligence (AI)-robotics-sentient media – the nexus of media, markets and violence is beginning to transform. This paper offers concepts and frames to start exploring the new patterns of linkages across media, markets and violence. 相似文献

Background: Lung cancer is one of the most prevalent cancers in the US. This study was designed to evaluate the actual drug wastage and cost to the healthcare system using patient-level retrospective observational electronic medical record (EMR) data from a cohort of lung cancer patients in the US.Methods: Data from the Flatiron Health advanced non-small cell lung cancer (NSCLC) cohort was used for this study. Drug administered amount (in mg) was used to determine an optimal set of available vial sizes to minimize waste. Drug wastage was defined as the difference between the drug amount in the optimal set of vials and the administered amount. Wholesale acquisition costs were used to value the cost of drugs, with and without vial sharing assumptions. The amount and cost of waste were quantified over the 2-year study period (January 2015–December 2016).Results: There were 8,467 eligible patients included in this study, providing data from 103,826 unique drug administrations across multiple lines of therapy. Overall wastage was 4.37% of the total medication used to care for patients. While costs per administration were low, the total cost of wastage for the study population represented $16,630,112 across the 2-year study period. Assuming that vial sharing occurred at the site level slightly reduced waste to 3.74% (reducing costs to $15,953,212 over 2 years).Conclusions: Drug wastage is an important concern and has implications on healthcare costs in NSCLC. Evaluation of these real-world data suggest that pharmacists and physicians are able to reduce drug wastage by optimizing vial combinations and sharing vials among patients. Even small amounts of reduction in wastage could be useful in reducing healthcare costs in the US; however, caution is needed with drug rounding efforts to ensure patients do not receive a sub-optimal dose of medication. 相似文献

The introduction of technology education in primary and secondary schools during the past 10–15 years around the world has
presented a number of difficulties for teachers, primarily related to their coming to understand the phenomenon of technology
and to conceptualise the technology learning area in line with national frameworks. This paper reports on a professional development
experience that aimed to assist a small group of primary school teachers to develop their understandings of technology and
technology education. A theoretical model framed a series of professional development interactions between the researchers
and the experienced teachers who were new to teaching technology. Data sources included teacher interviews, video recordings
of the activities, teacher made models, and extracts from their reflective journals. The study presented some insights into
how professional development experiences for teachers new to technology could be organised and implemented to best support
their developing technology practices and understandings. 相似文献

While decentralization is on the forefront of the reform agenda of many developing countries, few studies have performed empirical analysis to provide a holistic picture of the important fiscal, efficiency, and equity issues. Specifically, decentralization nearly always involves fiscal and administrative decisions by both national and sub-national governments, as well as intricate intergovernmental relations. Here, two empirical models are presented for the Mexican primary and secondary education sector. The first analyzes the efficiency-equity trade-off implicit the Mexican Federal Government's educational fiscal transfers to states. Unlike most similar analyses, this model analyzes the distribution of outcomes not simply expenditures. The second model analyzes the relative productivity of separate expenditures by the Federal and state governments before Mexico's recent educational decentralization legislation. The findings show that before the decentralization, the Federal Government exhibited some concern for equity, but that in doing so also treated states unequally according to criteria that have little to do with either efficiency or equity. In addition, the results show that the Federal Government may indeed have been the more efficient provider of primary and secondary education, raising concern for the fiscal and administrative relationship set up by the decentralization legislation: the Federal Government will continue to pay, while the states have gained relative autonomy over expenditures. 相似文献

An assessment of opponents' reactions to strategic and functional area policy decisions is shown to require knowledge concerning opponents' beliefs about the firm's behavior. This study introduces a methodology for incorporating such conjectures into the business planning process. It presents an analytical measure for these conjectural variations and discusses several illustrations. Examples of the application of the framework are provided by the Japanese flat glass industry and the U.S. domestic coffee roasting industry. The use of a broad range of conjectural variations in competitor analysis is discussed, and implications for business strategy formulation are highlighted. 相似文献

ABSTRACT This study sets out to examine two explanations for why employees engage in organizational citizenship behaviour (OCB). The first explanation views OCB as a form of reciprocation where employees engage in OCB to reciprocate fair or good treatment from the organization. The second view is that employees engage in OCB because they define those behaviours as part of their job. The research methodology consisted of survey data from 387 hospital employees on their perceptions of procedural and interactional justice, mutual commitment, job breadth and OCB. The results suggest that procedural and interactional justice are positively associated with mutual commitment that in turn, is related directly to OCB and indirectly through expanding the boundaries of an individual's job. These findings suggest that together the reciprocation thesis and ‘it's my job’ argument complement each other and provide a more complete foundation for our understanding of OCB. The difference between the two perspectives lies in the process by which individuals respond; that is, role enlargement and role maintenance. Implications and directions for future research are discussed. 相似文献
