A lab study examined the effect of type of ad claim (factual versus evaluative) and knowledge level on subjects' product feature inference making from three camera ads. Each ad had some missing brand information. The results showed that as knowledge increased, so did inference making. Also, there was a significant interaction between ad claim and knowledge. Inference making was positively correlated with knowledge level for factual ads but not for evaluative ones. Finally, subjects made very few inferences to fill in missing ad features but instead did more interpretive processing.  相似文献

This paper deals with multidimensional dynamic risk measures induced by conditional g‐expectations. A notion of multidimensional g‐expectation is proposed to provide a multidimensional version of nonlinear expectations. By a technical result on explicit expressions for the comparison theorem, uniqueness theorem, and viability on a rectangle of solutions to multidimensional backward stochastic differential equations, some necessary and sufficient conditions are given for the constancy, monotonicity, positivity, and translatability properties of multidimensional conditional g‐expectations and multidimensional dynamic risk measures; we prove that a multidimensional dynamic g‐risk measure is nonincreasingly convex if and only if the generator g satisfies a quasi‐monotone increasingly convex condition. A general dual representation is given for the multidimensional dynamic convex g‐risk measure in which the penalty term is expressed more precisely. It is shown that model uncertainty leads to the convexity of risk measures. As to applications, we show how this multidimensional approach can be applied to measure the insolvency risk of a firm with interacting subsidiaries; optimal risk sharing for ‐tolerant g‐risk measures, and risk contribution for coherent g‐risk measures are investigated. Insurance g‐risk measure and other ways to induce g‐risk measures are also studied at the end of the paper.  相似文献

The purpose of this study was to understand how the different domains of nutrition knowledge are related to health-oriented food behaviour and how both of these are related to socioeconomic factors. The studied population of homemakers (n = 647) answered a mailed questionnaire gathering socioeconomic data, food use data and data on nutrition knowledge. Items measuring both food behaviour and nutrition knowledge were chosen in the areas of fats and dietary energy because of their importance in the Finnish nutrition recommendations. The household context was chosen to increase the understanding of the knowledge-behaviour relationship in everyday settings. The major findings were: nutrition - related beliefs were the best predictors of health-oriented food behaviour (h.o.f.b.); factual knowledge had only weak connections with h.o.f.b.; education and income had stronger connections with h.o.f.b. than factual knowledge; and the connection of practical knowledge oriented with childhood implied that a homemaker's food behaviour was linked with habits adopted from childhood.  相似文献

It is widely acknowledged that obesity linked with reduced exercise contributes to health problems, and that, conversely, individuals who embark on weight reducing diets may become deficient in key nutrients. It is often advocated that these problems, which can be grouped together as poor dietary practice, be tackled through education. This study attempts to examine the relationship between nutrition education and lifestyle behaviours in a select group of third level students. The Irish Home Economics curriculum aims to teach secondary school pupils about nutrition and lifestyle practices conducive to health. However, the attitudes and lifestyle practices of those teaching this subject have never been examined in Ireland. The purpose of the present 4‐year longitudinal study, whose first year findings are presented here, is to investigate the nutrition and lifestyle knowledge, attitudes and behaviours of a cohort of Irish student home economics teachers over the 4 years of their Bachelor of Education (Home Economics) degree course. The study was designed to explore possible changes in knowledge, attitudes and practices over the course of their professional education. Nutritional knowledge was measured using a 220‐question adapted version of the test devised by Parmenter and Wardle. Attitudes were measured using a questionnaire adapted from the Pan‐EU Survey on Consumer Attitudes to Physical Activity, Body‐weight and Health. Food, alcohol consumption and exercise were measured using a 7‐day reported dietary/exercise diary. Nutrient intake data were determined using dietary analysis. Weight, height and waist circumference were measured and body mass index (BMI) calculated. When starting college, student home economics teachers have broadly similar anthropometric, dietary and lifestyle characteristics to those of their contemporaries. Mean BMI was identical [24.4 kg/m2 (SD 4.3)] to that reported in the North/South Ireland Food Consumption Survey (NSIFCS) for those aged 18–35 years, although energy intakes were significantly higher in the cohort of student teachers (P = 0.000). Thirty‐eight per cent were overweight or obese vs. 33.6% in the NSIFCS. Only 17% (n = 6) of students achieved an intake of 300 µg/day of folate as recommended by the Food Safety Authority of Ireland and only one the recommended intake of non‐starch polysaccharides (18 g/day). One in three students in this study smoke (16 of 48) and alcohol consumption was high. Only one student was very active. Students scored a mean of 55% (SD 8%) on the knowledge test, with similar scores attained for specific aspects of nutritional knowledge (i.e. food groups, constituents of foods, current dietary advice, nutrients, lifestyle practices). However, knowledge of nutrition definitions was weaker with a mean score of 31% (SD 8.6%). Students had a positive attitude towards food choice, the link between food and health and control over their own diet. Similar attitudes towards exercise, smoking and alcohol consumption were displayed despite students perceiving themselves as not having a balanced diet, having insufficient exercise and having regretted something done as a result of consuming alcohol. They appear to display optimistic bias in relation to health risks. These findings provide baseline data for the longitudinal study and indicate that those choosing to pursue a career as a home economics teacher in Ireland have similar nutritional and lifestyle characteristics to those of their contemporaries.  相似文献

Many complex decisions are made in a group environment, where the decision is made jointly by a committee or group structure. The individual group members are often not equally qualified to contribute equitably to the decision process, or may have different saliences (desires) to influence the decision. A quantitative knowledge of the players' decisional power is useful for better understanding of the group decision process, and could even be used in weighted voting within the group structure. We adapt the REMBRANDT suite of decision models (multiplicative AHP and SMART) to measure decisional power in groups, and we generalise this to cater for the case where power itself is deemed to be multidimensional in nature, and the case of uncertain subjective judgements of power amongst group members.  相似文献

School is a major area for providing young people with nutritional knowledge and skills. In Northern Ireland home economics (HE) is taught to 11‐ to 12‐year‐olds. The 1988 Education Reform Act introduced the national curriculum and HE as a subject was effectively abolished in English schools, and key stage 3 pupils in England are taught nutrition in Science, Design and Technology and in the cross curricular theme of health education. The aim of the study was to compare the attitudes and nutritional knowledge of children in Merseyside, England (M) and Northern Ireland (NI). A questionnaire was designed, which examined attitudes to aspects of healthy eating and tested the subject's knowledge, practical and theoretical, on nutrition and healthy eating. Subjects aged 11–12 years were recruited (M: 541, NI: 128). The majority ‘understood and knew what to eat to have a healthy diet’, ‘liked the taste of healthy food’ and considered that ‘there were healthy foods at home’. However, a significantly greater number in Merseyside agreed that ‘their health will be affected in the future by what they eat now’ (M: 71%, NI: 54%, P < 0.01) and agreed that ‘they enjoyed cooking’ (M: 76%, NI: 56%, P < 0.01). Whereas more from Northern Ireland agreed that ‘they do not know what foods to eat to have a healthy diet’ (M: 14%, NI: 30%, P < 0.01), ‘that healthy eating involved “dieting” ’ (M: 29%, NI: 59%, P < 0.01) and agreed that ‘there are no healthy food choices at school’ (M: 23% NI: 42%, P < 0.01). More subjects from Merseyside disagreed that ‘healthy eating is a waste of time’ (M: 87%, NI: 77%, P < 0.01). The mean knowledge scores (correct answers) from Merseyside were significantly greater than from Northern Ireland (total score: M: 51%, NI: 43%P < 0.05; practical score: M: 58%, NI: 49%P < 0.05, theory score: M: 38%, NI: 31%, P < 0.05). The results indicate that the healthy food message seems to have been better learnt by children in Merseyside but results of surveys in Merseyside into eating habits suggest that many have not put this knowledge into practice.  相似文献

This study examines the nutritional beliefs about fast-food restaurant meals held by a small sample of consumers. Views on the nutritional quality, caloric content, potential hazards and economic value of such meals were examined with respect to the socioeconomic level and nutritional knowledge of consumers. Findings indicate that consumers perceive these nutritional aspects of fast-food meals to be important but often ignore them in practice. Implications for consumer education and a need for greater social responsibility on the part of the restaurants are noted.  相似文献

In Finland there are valid questions being asked about the sustainability of the current provision in state healthcare systems. Structurally, lower birth rates and greater longevity mean that populations age and present the challenge of chronic illness management in later life for a larger proportion of the population. Culturally, some 50 years after the introduction of a state healthcare system, ageing populations will have greater expectations of service quality than their predecessors. Paradoxically, they will also have a greater engagement with lifestyles which themselves will bring new challenges to long‐term health status. There is no single solution to the complex problem of service sustainability but undoubtedly health education provides some potential to limit future demands. Diet‐related illness and incapacity are specific health challenges for the coming decades but the problems can be substantially reduced by changing current behaviour. To make such changes possible, knowledge needs to be communicated effectively in terms of simplicity, accuracy and with appropriate timing. Health education can make a major contribution to service sustainability. This paper reports a study of primary care nurses (n = 50) in the Tampere area and examines their capacity to provide healthy eating advice. In this sample, nurses often demonstrated good levels of nutritional knowledge on which to base patient advice, but there was considerable variation. Arguably, focused in‐service training would provide updating on theory and practice for more consistent advice and better prospects for behavioural change.  相似文献

Despite the importance of knowledge complementarities to inter-firm cooperation, few researchers in information systems (IS) have examined, to date, the construct of knowledge complementarities (KC), and none have examined its role in the success of IT outsourcing alliances. In this paper, we distinguish between potential knowledge complementarities (PKC) and synergistic value, which comprise KC. PKC is conceptualized as a multidimensional construct encompassing knowledge types (similar and specialized) and knowledge domains (business and IT). Further, we examine the extent to which PKC between the client and the vendor promotes success in IT outsourcing alliances. This research also includes relative absorptive capacity because it is relevant when complementary knowledge flows between organizations. We used data from a field study of 81 firms in Korea to test the proposed model. Our findings indicate that each dimension of PKC contributes uniquely to knowledge complementarities. The results also show that PKC is significantly associated with IT outsourcing effectiveness. Relative absorptive capacity is found to be a moderator between PKC and IT outsourcing effectiveness. The theoretical and practical implications of these findings are discussed in the paper.  相似文献

The ‘average consumer’ is referred to as a standard in regulatory contexts when attempts are made to benchmark how consumers are expected to reason while decoding food labels. An attempt is made to operationalize this hypothetical ‘average consumer’ by proposing a tool for measuring the level of informedness of an individual consumer against the national median at any time. Informedness, i.e. the individual consumer's ability to interpret correctly the meaning of the words and signs on a food label is isolated as one essential dimension for dividing consumers into three groups: less-informed, informed, and highly informed consumers. Consumer informedness is assessed using a 60-question test related to information found on a variety of Danish everyday food products and divided into factual questions and informedness about signpost labels. A test was made with 407 respondents who participated in four independent studies on fairness in consumer communication, and the average score for all was 57.6% of correct answers. A score of 64% and beyond would place a consumer in the upper quartile (the group of highly informed consumers), whereas a score of 52% or below would place the individual in the lower quartile (the group of less-informed consumers). Female respondents performed better than males on label recognition, and those around 40 years of age irrespective of gender performed best on factual knowledge, whereas those aged around 30 performed best on label recognition. It is foreseen that independent future studies of consumer behavior and decision making in relation to food products in different contexts could benefit from this type of benchmarking tool.  相似文献

This paper reports on a survey conducted at two major marketing centres in Ghana; Tamale in the dry savannah zone and Kumasi in the forest zone. One hundred traders were interviewed using a semi‐structured questionnaire and focus groups discussions held on traders’ perceptions and consumer preferences, relative importance and indigenous nutritional knowledge of traditional leafy vegetables (TLVs). The survey established that, with the exception of Xanthosoma mafafa (cocoyam leaves), inter‐market distribution of TLVs is limited because of their perishable nature, narrow utilization base and lack of storage techniques. Socio‐culturally related factors limiting the distribution of TLVs include regional diversity and ethnic differences in the dietary patterns of the Ghanaian populace, inadequate knowledge about the methods of preparations as well as nutritional and medicinal values of TLVs. The most preferred TLVs as reflected in the consumers’ buying behaviour and traders’ perceptions are Xanthosoma mafafa (cocoyam leaves), Corchorus spp.(Ayoyo), Amaranthus spp (Alefu) and Hibicus sabdariffa (Bra). The order of preference in the forest zone is Xanthosoma mafafa (cocoyam leaves) > Corchorus spp.(Ayoyo) > Amaranthus spp (Alefu) > Hibicus sabdariffa (Bra), while the reverse order pertains in the savannah zone.  相似文献

School is a major area for providing young people with nutritional knowledge and skills. In Northern Ireland home economics is taught to 11–12 years olds (CCEA,1998). The 1988 Education Reform Act introduced the national curriculum and home economics as a subject was effectively abolished in English schools. Key stage 3 pupils in England are taught nutrition in Science, Design and Technology and in the cross curricular theme of health education (SCAA, 1996). The aim of the study was to compare the attitudes and nutritional knowledge of children in Merseyside, England (M) and Northern Ireland (NI). A questionnaire was designed, which examined attitudes to aspects of healthy eating and tested the subject's knowledge, practical and theoretical, on nutrition and healthy eating.

The results indicate that the healthy food message seems to have been better learnt by children in Merseyside but results of surveys in Merseyside into eating habits suggest that many have not put this knowledge into practice.  相似文献

Although knowledge transfer contributes to a firm's competitive advantage, the effect of mechanisms used by a knowledge recipient on knowledge acquisition has been understudied. This article provides some insights on the interplay of knowledge recipients and transfer mechanisms between Japanese multinational corporations and their subsidiaries operating in China. Using structural equation methodology, this research proposes a knowledge transfer model that captures knowledge recipients’ characteristics and acquisition mechanisms, and empirically investigates the impact of knowledge recipients on mechanisms to test the applicability of specific mechanisms in knowledge acquisition. This article argues that knowledge recipients’ motivation and absorptive capacity have a positive impact on knowledge acquisition, and simultaneously provides evidence that mechanisms have mediating effects, which are vital to our understanding of knowledge transfer effectiveness. This study extends our understanding by adding knowledge transfer mechanisms as mediating factors in the relationship between knowledge recipients’ characteristics and knowledge acquisition, and quantifying the relationship. © 2015 Wiley Periodicals, Inc.  相似文献

The secondary market for antiques and collectibles represents a disorganized market channel characterized by competition for supply of rare goods and retail sales arising from non-traditional channels, loose ties among channel members, and largely unregulated transactions between buyers and sellers. This study explores how knowledge structures affect dealers' abilities to turn a profit in the antiques and collectibles market. Data were obtained from in-depth interviews with eight professional antiques and collectibles dealers operating in different regions of the United States. Findings indicate that while information is widespread, its credibility can be difficult to assess without some degree of product and market knowledge. Furthermore, the findings show knowledge plays a critical and somewhat differential role in the ability of professional dealers to turn a profit. Knowledge asymmetries that create favorable conditions for profits when dealers hold the balance of informational power in the upstream acquisition of antiques and collectibles ironically reduce dealers' ability to earn profits in downstream resale of these goods. Findings support a multidimensional view of knowledge as a broader concept, based on information and product and market expertise, but deepened by experiences that lead to tacit knowledge, which can be difficult to transmit.  相似文献

The focus of this research concentrated on ascertaining the presence of ethical climate types and the level of analysis from which ethical decisions were based as perceived by lodging managers. In agreement with Victor and Cullen (1987, 1988), ethical work climates are multidimensional and multi-determined. The results of this study indicated that: (a) benevolence is the predominate dimension of ethical climate present in the lodging organization as perceived by lodging managers, and (b) the local level of analysis (e.g. immediate workplace norms and values) is the predominate determinant of ethical decisions in the organization.The implication of this study is that the knowledge gained from understanding that ethical decision making in an organization is multidimensional and multi-determined will foster understanding of ethical decision formation in the organizational context.Randall S. Upchurch has a rich lodging industry background that encompasses 16 years of practical experience ranging from front office operations to hotel general management. He received his Ph.D. in May of 1993. He is the author of a text entitled Lodging Marketing. Sheila K. Ruhland is Assistant Professor of Marketing Education in the College of Education at the University of Missouri — Columbia. Her research interests are in area of workplace ethics, workforce issues, leadership development. She has conducted a seminar on Ethics and has published articles in the Marketing Educators' Journal, and Journal of Vocational Education Research.  相似文献

Purpose: This article measures to what extent export performance is affected by certain resource-based view (RBV) elements and seeks to elucidate relationships between these elements. Design: Among those RBV elements, knowledge and experience as resources, and marketing, production, product development, logistics, and service differentiation as capabilities, are chosen to be the basis of this research. Their effects on export performance are measured with a survey applied to personnel of Turkish manufacturing firms operating in Istanbul district. Findings: The results show us that marketing planning capabilities and service differentiation capabilities have a significant effect on export performance. The overwhelming effect of knowledge and experience of firms on marketing planning capabilities is one of the intriguing findings. Notwithstanding that, we found no trace of a relationship between product development capabilities and service differentiation capabilities. Value: This research provides several managerial and academic implications by contributing to a resource-based view in terms of knowledge and capabilities. Additionally, in this study, it is underlined that collective knowledge is vital for achieving high export performance.  相似文献

This study provides evidence for how factual (directly relevant for developing creative solutions) vs. range (indirectly relevant) information can be used to provoke idea generation and effective creative outcomes. Data were obtained from 127 staff, faculty, and students at a private Midwest university. The results show that the effect of type of information was moderated by the participant's creative thinking skill and domain knowledge. For individuals high in creative thinking skill, range information improved idea generation originality, which in turn enhanced creative outcome novelty but reduced outcome usefulness. Factual information, under various conditions, both helped and hindered creative outcome usefulness. Overall, presenting information during idea generation can improve creative outcome effectiveness. Managers should be careful to present the appropriate information at the appropriate time, however.  相似文献

This study explores the personality of Internet media and develops a multidimensional measurement scale to assess personality across diverse entities, including social networking sites, search engines, portals, and shopping sites. Through a series of qualitative and quantitative methods, including exploratory factor analysis and confirmatory factor analysis, the present study identifies a set of 30 personality traits that represent five unique dimensions of Internet media personality: Intelligent, Amusing, Convenient, Sociable, and Confusing. This study found that different pairs of brand and Internet media personality dimensions yield different effects on attitude toward advertising brands. Practical implications for marketers and advertisers, as well as theoretical implications for advertising researchers, are discussed.  相似文献

The nutritional status of children can influence their health and the risk factors for developing chronic diseases later in life. Korea is unique in that it is relatively westernized and yet maintains much of the traditional foods and cooking methods. Effective nutrition education should help children to choose a healthy diet through the establishment of positive dietary practices and habits. The main purpose of this research is to compare awareness towards nutrition education between primary schools in the UK and Korea and nutritional knowledge that children and parents have in these countries. Dietary and healthy eating knowledge data were collected by a questionnaire as part of a case study comparison using one primary school in Manchester, UK, and one in Seoul, Korea. A total of 171 primary school children and 124 parents of the children were recruited. The results indicated that children and parents appeared to be aware of the importance of limiting fat, sodium and sugar intakes, and requiring non‐starch polysaccharide (NSP). However, in the case of some foods they did not have satisfactory nutritional knowledge of which foods were high in fat, salt, sugar and NSP. British children had a better understanding of the health implication of fat than Korean children, whereas more Korean children considered excessive salt intake harmful than British children. There seemed to be differences in dietary pattern and familiarity with food between the two countries. Children identified parents as the main source of nutritional information. Therefore, parents as well as children need to learn about nutrition in order to give appropriate information or advice to improve the diets of their children. Children preferred exciting, fun, positive and a practical approach to learning about nutrition, such as computer packages and cookery classes. Parents wanted schools to give their children more information about nutrition. This research has shown that nutrition education in schools should be concerned not only to provide nutritional knowledge but also to encourage children to choose healthy food by redesigning nutrition education and school meals.  相似文献
