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

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

We reconstruct the level-dependent diffusion coefficient of a univariate semimartingale with jumps which is observed discretely. The consistency and asymptotic normality of our estimator are provided in the presence of both finite and infinite activity (finite variation) jumps. Our results rely on kernel estimation, using the properties of the local time of the data generating process, and the fact that it is possible to disentangle the discontinuous part of the state variable through those squared increments between observations not exceeding a suitable threshold function. We also reconstruct the drift and the jump intensity coefficients when they are level-dependent and jumps have finite activity, through consistent and asymptotically normal estimators. Simulated experiments show that the newly proposed estimators perform better in finite samples than alternative estimators, and this allows us to reexamine the estimation of a univariate model for the short term interest rate, for which we find fewer jumps and more variance due to the diffusion part than previous studies. 相似文献

An empirical study investigates the extent to which affective-symbolic and instrumental-independence psychological motives mediate effects of socio-demographic variables on daily car use in Sweden. Questionnaire data from a mail survey to 1134 car users collected in 2007 were used to assess the relationships daily car use as driver or passenger have to sex, household type (single or cohabiting with or without children), and residential area (urban, semi-rural or rural). Reliable measures of affective-symbolic and instrumental-independence motives were constructed. The results show that households with children use the car more than households with no children, that men make more car trips as drivers than women who use the car as passenger more than men, and that households living in rural areas use the car more than households living in semi-rural areas who use the car more than households living in urban areas. An affective-symbolic motive partially mediates the relationship between the number of weekly car trips and sex, the instrumental-independence motive partially mediates the relationships between weekly car use and percent car use as driver and several of the socio-demographic variables (living in urban vs. rural residential area for both measures; sex and living in urban vs. semi-rural residential area for percent car use as driver). Of several other socio-demographic variables (age, employment, and income) affecting car use, only the relationship of the number of cars to percent car use as driver was (partially) mediated by the instrumental-independence motive. 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

Injuries due to foreign body (FB) aspiration/ingestion/insertion represent a common public health issue in paediatric patients, which causes significant morbidity and mortality. The aim of this study is to present a Bayesian Network (BN) model for the identification of risk factors for FB injuries in children and provide their quantitative assessment. Combining a priori knowledge and observed data, a BN learning algorithm was used to generate the pattern of the relationships between possible causal factors of FB injuries. Finally, the BN was used for making inference on scenarios of interest, providing, for instance, the risk that an accident caused by a spherical object swallowed by a male child aged five while playing leads to hospitalization. BNs as a tool for quantitative risk assessment may assist in determining the hazard of consumer products giving an insight into their most influential specific features on the risk of experiencing severe injuries. 相似文献
