In the context of underground coal mining industry, the increased economic issues regarding implementation of additional safety measure systems, along with growing public awareness to ensure high level of workers safety, have put great pressure on the managers towards finding the best solution to ensure safe as well as economically viable alternative selection. Risk-based decision support system plays an important role in finding such solutions amongst candidate alternatives with respect to multiple decision criteria. Therefore, in this paper, a unified risk-based decision-making methodology has been proposed for selecting an appropriate safety measure system in relation to an underground coal mining industry with respect to multiple risk criteria such as financial risk, operating risk, and maintenance risk. The proposed methodology uses interval-valued fuzzy set theory for modelling vagueness and subjectivity in the estimates of fuzzy risk ratings for making appropriate decision. The methodology is based on the aggregative fuzzy risk analysis and multi-criteria decision making. The selection decisions are made within the context of understanding the total integrated risk that is likely to incur while adapting the particular safety system alternative. Effectiveness of the proposed methodology has been validated through a real-time case study. The result in the context of final priority ranking is seemed fairly consistent.  相似文献

Scandals in companies such as Enron have been a source of great concern in the last decade. The events that led to a global financial crisis in 2008 have heightened this concern. How does one account for executive behaviors that led to such a crisis? This article argues that a conjunction of motive, means, and opportunity creates ‘an ethical hazard’ making questionable executive decisions more probable. It then suggests that corporate unethical behavior can be minimized by creating a process to identify and remove such ethical hazards, and by appointing an ‘ethical hazards marshal.’  相似文献

Increasing interest in health and well‐being is likely to drive a growth in demand for products that have positive effects on health. Consumers’ acceptance of and willingness to buy functional foods has been widely studied, but there has not been research on consumers’ attitudes towards innovative non‐edible products with health effects. This study examines how older consumers perceive functional foods and novel non‐edible health‐enhancing products, how willing they are to purchase such products, and how health orientation influences their views. As an example of a ‘radical’ innovation, consumers’ acceptance of rubbing their hands in a specific soil‐based mixture to modulate the immune system is explored. The research material, 13 thematic interviews, was collected in Lahti region, Finland, in 2015. The study indicates that the older consumers’ market is not homogeneous. Based on a qualitative, in‐depth approach, the study distinguishes four consumer segments with different lay understandings of health and attitudes towards health‐enhancing products, which influence people's willingness to purchase such products. The segments are health‐seeking consumers, cautious consumers, critical consumers and natural health consumers. Various motives and barriers for using products with health claims are also identified. The case of rubbing hands in organic soil‐based mixture indicates the difficulty of predicting which consumer segment will first adopt this kind of ‘radical’ innovation. The results highlight that the credence qualities of a novel product must be communicated and advertised before entering the market while also taking into account the sensory properties of the product. ‘Radical innovations’ must be in a form that consumers can easily accept.  相似文献

Consumer participation in the evidence‐based health‐care movement is largely seen as important by those who promote evidence‐based health care but is surrounded by a range of competing discourses that variously critique medicine, nursing or health‐care systems; situate consumers as powerless players within systems characterized by controlling health professionals; or politicize the role of the consumer as activist and defender of patient rights. This paper explores these competing discourses and develops an argument that asserts that the social construction of the evidence‐based movement has rendered previously accepted terminology regarding the user or receiver of health services relatively meaningless. The result has been the ‘politicisation’ and ‘professionalisation’ of consumer participation and the time has come to reconstruct consumer participation in evidence‐based health care – from the generation of evidence to guideline development.  相似文献

The unprecedented dissemination of digital technology has changed people's psychology including their shopping behaviour in the last two decades. Smartphone led digital applications and advancements have disrupted consumers' shopping processes, purchase decisions, and priorities as well as increased their exposure, aspirations and expectations inevitably. Therefore, it is imperative to examine the relevance of various elements of shopping motives holistically. Therefore, the present study aims to develop a new theoretical framework based on significant elements of shopping motives for physical products in the digital technology era. For this purpose, an exploratory study, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equation modelling (SEM) were used. EFA generated five latent factors by grouping 18 independent variables. CFA validated latent factor construct and measured model fit. SEM visualized the path analysis and portrayed the pattern of relations between latent factors into a single factor structural model (consumer shopping motives framework). Results show that consumers' shopping priorities are changing as 3 conventional variables (‘role-playing’, ‘status and authority’, and ‘pleasure of bargaining’) became obsolete and 3 new (‘anywhere and any-time shopping’, ‘safe and secure digital transaction’, and ‘unbiased reviews and ratings”) came into existence prominently. The format and perspective of ‘fun, entertainment and recreation’ ‘social interaction and communication’, and ‘exposure to new and latest trends' have been changing. Consumers are becoming more technology-dependent in their shopping processes and purchase decisions. The validation of the framework on channel preference behaviour revealed that consumers largely prefer offline channels for the fulfilment of risk-free and social sub-motives, and online channels for convenience sub-motive. Therefore, broad structural change and clarity, specification of priorities, a shift in the format and perspective of few elements of shopping motives, intrinsic passion for the use of digital technology and web service in the shopping journey, and simplification of antecedents for growing popularity of multi-channel shopping paradigm are the key novelty of this study.  相似文献

The paper presents the results of research aimed at developing a risk assessment process that can be used to more thoroughly characterise risks associated with loader- and dozer-related fatal incidents in US mining. The assessment is based on historical data obtained from the US Mine Safety and Health Administration investigation reports, which includes 77 fatal incidents that occurred from 1995 to 2006. The Preliminary Hazard Assessment method is used in identifying and quantifying risks. Risk levels are then developed using a pre-established risk matrix that ranks them according to probability and severity. The resulting assigned risk value can then be used to prioritise risk control strategies. A total of 10 hazards were identified for loaders. The hazards 'failure to follow adequate maintenance procedure' and 'failure of mechanical/electrical/hydraulic components' were the most severe and frequent hazards and they fell into the category of 'high' risk. The same number of hazards was identified for dozers. The hazard 'failure to identify adverse site/geological conditions' was the most severe and frequent hazard and it fell into the category of 'high' risk.  相似文献

This paper sheds light on some unexpected consequences of health insurance regulation that may pose a big challenge to insurers' risk management. Because mandated uniform contributions to health insurance trigger risk‐selection efforts, risk adjustment (RA) schemes become necessary. A good deal of research into the optimal RA formula has been performed. A recent proposal in Switzerland has been to add ‘Hospitalization exceeding three days during the previous year’ as an indicator of high risk. Applying the new formula to an individual Swiss health insurer, its payments into the RA scheme are predicted to increase substantially, reaching up to 13% of premium income. Its mistake had been to implement Managed Care successfully, resulting in low rates of hospitalization. The expected risk management response is to extend hospital stays beyond three days, contrary to stated policy objectives.  相似文献

This study explores group package tour (GPT) itineraries based on comparative risk methodology using the fuzzy Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE). It combines the concepts of fuzzy sets to represent the uncertain information in intrinsic risks with PROMETHEE, a subgroup of Multi-Criteria Decision Making methods. Based on in-depth interviews with 40 GPT leaders, this study identifies comprehensive intrinsic risk factors. Furthermore, this study compares the risk perceptions associated with 12 factors by applying traditional PROMETHEE and fuzzy PROMETHEE methods to four itineraries. The PROMETHEE method can be used when the input data are numeric and crisp. The fuzzy PROMETHEE method is preferred when substantial uncertainties and subjectivities exist in GPT itinerary information. Finally, several academic and managerial implications about GPT tour risk controls are outlined.  相似文献

This article examines the importance of path dependence effects in impeding the diffusion of high throughput mechanized mining systems in the British coal industry. It demonstrates that the industry had become ‘locked in’ to low throughput underground haulage technology, on account of institutional interrelatedness between Britain’s traditional practice of extensive in-seam mining and its unique system of fragmented, privately owned mineral royalties. Fragmented royalties prevented the concentration of workings and introduction of high throughput main haulage systems that underpinned the rapid productivity growth of European producers. Meanwhile, technical interrelatedness between the haulage systems taking coal to the pit shaft and operations further ‘upstream’ created bottlenecks which both slowed the overall rate of mechanization and limited the productivity gains from the mechanization that did occur.  相似文献

It has been acknowledged that it is only by obtaining a more detailed understanding of food choice that people’s diets can be improved. In Northern Ireland, research into food choice has been limited yet the Province has the second highest rate of heart disease in the world, indicating the need for change. This study investigated the food choices of 9‐ to 17‐year‐olds in Northern Ireland and the influential factors. A range of research techniques were employed incorporating both qualitative and quantitative methods, namely observations, focus groups, picture associations, dietary case studies and questionnaires. The research indicated that the dietary patterns adopted by this group are characterized by a high consumption of fat, yet the reduction of fat tends to dominate the overall strategy for the prevention of obesity and lowering the risk of coronary heart disease. In addition, a high consumption of sugar products was evidenced along with a distinct dislike for healthier alternatives such as fruit and vegetables. The ‘skipping’ of meals, especially breakfast and a high prevalence of snacking was also apparent. However, these eating habits were found to be affected by various factors such as age and gender, emphasizing the complex nature of food choice. The findings from this research enabled the development of a model relating to the food choices of 9‐ to 17‐year‐olds in Northern Ireland, highlighting the influential factors and subsequent health implications.  相似文献

This qualitative study examined the consumption of Indian foods among groups of English and Indian people living in the UK. Both convenience and freshly made Indian foods were included in the research. The aim was to explore attitudes (based on ethnicity) towards, and the consumption of, Indian foods. The means–end model and laddering methodology were used in interviews with 24 respondents, 12 from each group (English and Indians). The personal values ‘social life’, ‘health’, ‘adventure’, ‘enjoyment’ and ‘savings’ were found to be the most important for English respondents whereas ‘enjoyment’, ‘good life’, ‘health’, ‘religion’ and ‘culture’ were the most desirable value ends for Indians. The results provide an insight into English and Indian peoples’ perceptions of Indian food that can be used in promotion and marketing positioning of branded Indian foods, sauces and accompaniments.  相似文献

This paper is intended to raise risk management as a topic for discussion among product safety professionals and discuss one particular key element of understanding risk. Risk management is an essential part of good product safety management, whether at the policy level or the implementation stage, and is relevant to all those involved in the development and use of standards, including regulators and suppliers. The risk management process involves measuring the risks at the initial stage, by looking at consequence (possible injury) and likelihood (of that injury occurring) which then gives us the ‘inherent risk.’ We then seek ways to treat the risks. A second assessment of the risks is subsequently done to establish the extent to which the treatment will address the problem (‘assessed risk’). In product safety, this means how dangerous is the product as it is and how effective will a measure be in reducing the risk. Communication is vital in this process. When standards are developed and policy adopted, the factors that are taken into consideration need to be properly documented. The rationales for decisions, i.e., what the hazard is and how it is treated by the product specification, should be recorded within the standard itself. In the absence of recorded reasons, assumptions are made and these may well be incorrect. This paper discusses this topic in some detail and provides illustrative examples.  相似文献

In this article the major elements of the 30 year old Asian development model are examined in the light of the financial crisis in the region. The notion of a common model is examined and found to be overstated. The monetary crisis in Asia has affected countries to different degrees, with Indonesia and Korea being particularly weakened. Korea has two major economic problems which can be traced to economic policies established in the 1960s. First, the industrial organization of the economy under a few industrial conglomerates, which has outlived its usefulness and is now a major source of the troubles in the economy. The conglomerates have been responsible for an investment policy where risk has been pushed to recklessness and the rate of return on capital employed is meagre. Second, banking policy, which is best characterized as a severe form of ‘moral hazard’. Both of these policies, while having played major parts in past economic successes, are now the main cause of a weakened economy in a globalized world.  相似文献

As the public interest in health information has increased globally, the use of health benefits in food advertisements is becoming more essential for food marketing strategy. Consumers view a food product as healthy if it carries a health claim, whereas there has been an ongoing debate about the value of health claims as a strategy to help consumers’ healthier food consumption. The present study attempted to examine the food commercials broadcast on Korean network television in terms of claim types and executional elements. Results indicate that television food advertising has made a wide number of implied “soft” health claims (e.g., “good for health”) without substantial information and call into question whether consumers are misled or deceived by the executional elements used for presenting health messages. The findings of the study raise regulatory concerns about the provision of potentially confusing or misleading health messages in food advertising nationally as well as internationally and suggest further research in this area.  相似文献

Since its conception in 1945, the UK National Health Service (NHS) has been the focus of extensive political rhetoric regarding the involvement of patients and the public in the provision of health‐care services both locally and nationally. However, achieving substantial user involvement within local communities has proven to be a complex task. The exploratory research presented in this paper investigates the influence of social networks within local communities and its relevance for user involvement. Four main findings emerged: interviewees have strong informal social networks; there is a strong sense of generalized reciprocity; diversity is limited within the social groupings; and there exists a lack of trust in governmental institutions. With regards to health issues, there is an overriding feeling that ‘things like that should be left to the people who know’. If user involvement is to be achieved at the level envisioned by the UK government, achieving a greater relevance for users is essential.  相似文献

Foreign market entry strategy involves choices about which markets to enter and how to do it. Most of the literature on foreign direct investment reflects an interest in ownership structure decisions and the risks foreign investing firm may face. As recognized in many studies, one set of risks arises from public expropriation hazards, a function of the ability of the host country's institutional environment to credibly commit to a given policy or regulatory regime. Empirical research has shown this hazard to have an impact on ownership levels. This study is a theoretical model that describes how multinational firms face moral hazard risk from their local partners and political risk from the host country when they decide to go abroad in a joint-venture alliance. I found that the greater the level of hazard expropriation, the lower the participation of the multinational firm in the final cash flow, except for when the multinational firm has the negotiation power and there is a high level of local investment protectionism. In that case, the multinational firm increases its participation in the final cash flow.  相似文献
