The aim of this study was to investigate consumer preference for the novel red-fleshed apple genotypes. The information presented provides us with insight into consumer propensity to accept a new variety with radical visible innovative attributes and societal demand for a more sustainable production. The survey was carried out on the population of a province in central Italy, where there is consumer demand for organic and high-quality foods. The consumers’ opinions contrasted greatly and can be divided into two groups. Over one quarter of the respondents declared that they did not like the innovative fruit. The cluster analysis and CHAID analyses were performed on the consumers’ responses to determine sample groupings. Three clusters were identified among the consumers with positive opinions, enthusiastic, health-conscious, and unmotivated illustrating how the hierarchical level of preferences of the potential consumers of the red-fleshed apple fruit are triggered by various motivations. The surveys also pointed out that most consumers of the sampled population were not biased against research activities producing innovative food products. A large number of consumers, especially women, declared that they were willing to pay a higher price considering the increased nutritional value of red-fleshed apple fruits. By examining the broad context of this study, decision-making researchers and operators of the fruit industry will be able to make informed and realistic predictions concerning possible future scenarios and to determine the possible effects and desirability.  相似文献

The Pão de Açúcar Group was a pioneer in food retailing in Brazil and is now one of the largest Brazilian retailers. Working in a pulverized market characterized by small players, the Group produces US$ 20.4 billion in gross sales. It has become the largest employer in the country with 140,000 of employees working in over 1,800 stores, in 18 of the 25 states in Brazil, and covering a sales area of over 2,800,000 m2 (Grupo Pão de Açúcar, GPA Consolidado. Resultados 3T12. São Paulo, Brazil, p. 2. November, 1, 2012). The objective of this article is to analyze a business inclusion strategy of the Pão de Açúcar Group. The Caras do Brasil Program (Faces of Brazil) was created in 2002, by the Group directors as an effective initiative, aiming to develop a new sales channel for sustainably handling products. The Program opens opportunities for small suppliers, not only in the Pão de Açúcar chain but also among competitors and in other industries. The Program established some requirements for the producer to become a supplier, aiming to adapt the products to a regular commercialization with the Group. In this way, small producers can now rely on a complete business process, while beforehand the goods were sold mostly through small channels.  相似文献

This study investigated the effect of information on the acceptability and purchase intention of an irradiated watercress salad and its non-irradiated counterpart among Brazilian consumers (N = 236). Both the irradiated and the non-irradiated products were fairly accepted (ratings about 6.0–7.0 in the hedonic scale). Significant effects (p ≤ 0.05) of gender, education, and age were also observed: acceptance and purchase intention was lower among male participants who received both information and an identified irradiated product, and higher among female participants who received only information about the process. Adults (30–39 years old) were more critical, and the higher the educational level, the lower the acceptability and purchase intention ratings. Brazil is one of the major irradiators in the world, but there is still a lack of consumer studies focusing the acceptability of irradiated foods. So the findings presented herein would favor Brazilian producers and regulators to develop effective communication strategies and to promote the irradiation technology.  相似文献

The aim of the study was to map the field of internal and external conditions that Swedish Home and Consumer Studies teachers and pupils have contend with. A questionnaire was constructed and delivered online in November 2010. It contained 27 question covering teacher qualification, quality of premises and equipment, lesson time and collaboration, and the use of national syllabi. A total of 385 persons across the country answered the questionnaire; about 21% of those teaching Home and Consumer Studies in Swedish compulsory school during the school year 2009–2010. These respondents taught in a total of 392 compulsory schools, which equalled about 22% of the schools teaching grades 7–9 in Sweden. Almost a quarter (23%) of the teachers lacked formal training for Home and Consumer Studies. Respondents without an appropriate degree qualification included those trained as nursery school teachers, dietitians and civil engineers. As regards classrooms, while 88% of respondents reported access to fully equipped kitchens with stoves, sinks and work surfaces, 5% used regular classrooms and the remainder were obliged to come up with alternative solutions, such as using portable kitchens in regular classrooms or conducting their lessons in the school restaurant. This study raises many questions about the quality of Home and Consumer Studies provision in a number of schools. The local deficiencies in the nationally decided frame factors for Home and Consumer Studies found by the present study gives us reason to doubt that all pupils achieve the overall learning goals of ‘knowing in practice’ and making informed choices utilizing environmental, economic and health perspectives. This might affect the health and economy of the individuals in the long run, with implications for the national economy and public health. On the basis of these findings, we therefore recommend that current conditions for Home and Consumer Studies and how the subject should operate in schools become a focus for national debate.  相似文献

The present study adds to the CMO literature the perspective of firms’ imitative behavior on why firms have CMOs in their TMT. We propose that a firm’s decision to have a CMO on its TMT is driven not only by contingency-reated considerations but also by social ones, as the decision is significantly influenced by industry peers. Empirical findings based on 505 large US firms from 2000 to 2012 indicate that firms’ imitative behavior is a significant driver of CMO presence, especially when firm uncertainty is strong and inference uncertainty is low. Post hoc analyses indicate that this imitation behavior tends to be performance neutral at best.  相似文献

I develop a dynamic model of optimal funding to understand why financial assets are used as collateral instead of being sold to raise funds. Firms need funds to invest in risky projects with nonobservable returns. Since holding these assets allows firms to raise these funds, investing firms value the asset more than noninvesting ones. When assets are less than perfectly liquid and investment opportunities are persistent, collateralized debt minimizes asset transfers from investing to noninvesting firms and thus is optimal. Frictions in asset markets lead to an illiquidity discount and a collateral premium, which increase with the asset’s illiquidity.  相似文献

This paper looks at the channels through which intangible assets affect productivity growth. The econometric analysis exploits a new data set on intangible investment (INTAN‐Invest) in conjunction with EUKLEMS productivity estimates for 10 EU member states from 1998 to 2007. We find that (a) the output elasticity of intangible capital depends upon ICT intensity, consistent with complementarities between ICT and intangible capital; (b) non‐R&D intangible capital has a higher estimated output elasticity than its factor share, as does (c) an index of labour composition. The last two findings are consistent with growth spillovers from investments in knowledge‐based/intangible capital and skills.  相似文献

We consider a model of wage determination with private information in an oligopoly. We investigate the effects of unions having relative concerns on the negotiated wage and the strike activity. We show that an increase of unions’ relative concerns has an ambiguous effect on the strike activity.  相似文献
