In many countries, changes in the pattern of working lives and ageing of the population increases the need for professional cleaning in private domestic homes. The objective of this study was to obtain basic knowledge concerning professional home cleaning. The study consisted of two parts. First, cleanability of surfaces contaminated with microbiological and organic soils was examined in the laboratory using cleaning cloths, detergents and rapid detection methods with potential for use in conjunction with professional cleaning in private homes. Second, hygienic conditions in three households were screened using the same rapid detection methods as in the laboratory experiments. According to the laboratory study, the cleaning efficiency of the non‐woven cloth was clearly poorer than that of the cleaning cloths containing microfibers. There were differences between the efficacy of the cleaning agents in removal of protein and microbiological soils. Despite the differences between surface topography observed with scanning electron microscopy, differences between the cleanability of the three examined surface materials (steel and two plastic surfaces) were small. In hygiene monitoring, the highest levels of total aerobic bacterial counts were detected in the plughole of the sink, on the eating table in kitchens and along the edge of the toilet washbowl and the cover of toilet seats. Low amounts of Enterobacteriaceae indicating faecal contamination were detected in the toilet and bathroom after cleaning. Moulds were not detected in any of the three households, and the amounts of yeasts were low. Detection methods, microbiological dipslides and the protein test, were well suited to the laboratory study. Furthermore, they complemented each other in the hygiene monitoring. The information obtained will be used for development of better practices in professional home cleaning. Good quality management in professional home cleaning and the cleanliness of surfaces in homes are important factors affecting comfort and safety. 相似文献

Economic theories of commercial nonprofits and mutuals usually emphasise the advantages of such organisational forms in reducing agency and monitoring costs in markets that suffer from information asymmetries in exchanges between firms and their customers. This article examines the ability of such transaction cost theories to account for historical variations in the ownership and governance of firms in the US personal finance industry between the early nineteenth century and the Great Depression. It focuses, in particular, on mutual savings banks and their role in the development of the intermediated market for savings accounts. While I find some evidence in support of transaction cost theories of organisational form, I also find that entrepreneurial and socio-political factors played crucial roles in the choice of ownership and governance structures; mutual savings banks predominated in the early years of the industry because the form offered entrepreneurial advantages over investor-owned corporations and because in some states they benefitted from regulatory and political advantages that joint-stock companies lacked. Their relative decline by the early twentieth century was the result of increasing competition in the market for savings deposits, the loosening of regulatory barriers to entry, and changes in public policy that reduced the transaction, innovation and regulatory advantages that the mutual savings bank form had once held. The article draws out the theoretical implications for our understanding of the historical role of nonprofit and mutual firms. 相似文献

AbstractThis appraisal considers the role and impact of vocational education and training (VET) in Australia and New Zealand, and suggests directions such policy might take in other Asia-Pacific countries. It identifies key issues and constraints in making VET more responsive to emerging labour market needs in the region as an important factor in sustaining high economic growth. It focuses on the way in which the demands of the government, industry, trainees, and, in particular, shifts in political ideology that have influenced the education and training sectors in both countries. It addresses points of specific relevance for the delivery of VET in the broader Asia-Pacific context and concludes with a consideration of lessons and experiences of Australia and New Zealand with VET that may hold for other countries in the region in formulating priorities and implementing strategies in meeting their current and emerging needs for skills development. 相似文献

The potential of blockchain technology (BCT) to modify and innovates established business structures and frameworks has received widespread attention. Academia and businesses are becoming increasingly curious about how this technology could be used to improve and refine consumer services and operations. Despite the growing popularity of blockchain research in consumer services, there remains a dearth of detailed summaries in the literature. Hence, this bibliometric analysis, combined with a systematic literature review (SLR) using SPAR-4-SLR protocol with the theories, characteristics, contexts, and methods framework (A hybrid review), aims to convey qualitative and quantitative knowledge on the ever-evolving subject of blockchain application in consumer services in an organized manner. Specifically, this article analyses: (1) the current publication trends in studies devoted to blockchain-based applications for consumers, (2) the most important publications and themes of research in this field, (3) the evolution of blockchain in consumer service over the years, and the most current trends in this field, (4) the advantages and challenges of incorporating BCT into consumer services, (5) gaps in the existing literature that future researchers should investigate. In addition, this review also describes the widely used theories, characteristics, and methods in the application of blockchain in consumer service research by examining the most applied theories, methods, constructs, and study contexts and paving the way for new research directions. The review includes 417 documents after searching for scholarly publications in two databases (Web of Science and Scopus) and choosing documents based on their relevance to the stated goals. 相似文献

Home economics and civics as school subjects in Japan have a common feature, in that both subjects nurture a sense of citizenship at home, in the workplace and in the wider society. In addition, both have the potential to help students recognize the gender bias around them and can empower them to help make a more gender‐equal society. Focusing on this, the purpose of this report was to investigate home economics and civics teachers’ views, in order to analyse the features of the two subjects and the relationship between them. Questionnaires were sent to home economics and civics teachers of all the senior high schools in four prefectures around Japan in October 2001, and 357 samples were analysed. The results were as follows: (a) Home economics teachers and female teachers expressed more interest in lessons on gender than civics teachers and male teachers. Concerning lessons on citizenship, no statistical difference in teachers’ interest was found. (b) Topics on citizenship were learned in the fields of consumer, environment and social welfare issues in both subjects. More lessons were reported to take place in home economics than in civics. (c) In home economics, topics on gender were learned as core issues in the areas of family relations, family law and parenting. On the other hand, in family law, civics, topics on gender were taught as marginal issues in the area of basic human rights and labour issues. (d) Home economics teachers thought the goals of gender education were to empower students to overcome narrow gender roles and to strengthen self‐respect. In contrast, civics teachers thought it would empower a sense of human rights. Concerning citizenship education, teachers of both home economics and civics thought the goals would enable students to recognize social problems as their own issues and try to solve them. 相似文献

Following Lavelle, Rupp, and Brockner's ( 2007 ) target similarity framework, we propose that perceptions of support and career satisfaction mediate the influence of justice perceptions on citizenship and counterproductive performance. Structural equation modelling results from 356 employees supporting partial mediation. Collectively, the model explained 19% of the variance in perceptions of organizational support, 44% in perceived supervisor support, 33% in career satisfaction, 35% in citizenship performance directed toward the supervisor, 42% in citizenship performance directed toward the organization, 49% in job/task conscientiousness citizenship performance, 9% in counterproductive performance toward the supervisor, and 20% of the variance in counterproductive performance directed toward the organization. We argue that distributive, procedural, informational, and interpersonal dimensions of organizational justice follow different pathways and variously influence organizational outcomes. We discuss the implications of the results for the target similarity framework and more generally for human resources management. Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd. 相似文献

劳资双方具有一种逻辑关系,表现为资本优先,劳资平衡,劳方优先三阶段。当代资本主义正处在劳资平衡的第二历史阶段。社会主义市场经济条件下劳资关系正处在第一历史阶段即将结束,并开始向第二历史阶段过渡时期。在这一过渡时期,政府在节制资本,保护劳工,劳资兼顾方面还存在一系列的难题:政府在节制资本、调控初次分配方面能力有限,保护劳工方面作为不够;工会组织在维护劳工权益方面比较软弱;社会主义民主制度在确保劳工各项权利方面有待进一步完善。由于劳资双方强弱明显,加快了中国社会分配的两极分化,这应引起我们的极端重视。 相似文献

As an affluent and warm weather country, Australia faced an epidemic of drowning in children under five as the popularity of home pools increased in the late 1960s and early 1970s. In one state child drowning rose by 6.62 per 100,000 in the five years from 1968. Variation across jurisdictions in actions to regulate domestic pools has resulted in Australia representing an unfortunate natural experiment in interventions to prevent child drowning in pools. Mechanisms adopted by various authorities were analysed in detail to identify factors that contributed to success and failure in regulating domestic pools. Despite early identification of the problem and development of what were later demonstrated to be effective interventions, best practice solutions were not established in any jurisdiction until 2002, 25 years after identification of the problem. Key failures in intervention were found to be: failure to act in a timely way, flawed regulation, blockage of timely action and repeal of effective state regulation under political pressure, and blockage of effective standards. Lessons are identified as: inherent weaknesses in the standard setting process, failure of interventions to address major risk categories, failure to act before the hazard grew, failure to consider lesser interventions for tactical reasons, failure to pay attention to advocates, and the need for continuing effort. The paper argues that analysis of the identification of the problem, development of interventions and implementation of mechanisms of prevention illustrate where systemic changes are required and indicate lessons that should be applied in developing and implementing future interventions. 相似文献
