The main objective of this paper is to study the concept of convenience orientation among young adults. A project was conducted among students living in residence halls, where information on their food motivation and behaviour was obtained. Data were collected using a self‐administered questionnaire filled out by 319 students. Convenience ap‐pears to be the most important food motivation followed by price, pleasure, health and concern about weight. Positive correlations were obtained between convenience and: deciding what to eat, having a varied diet and lack of time, all of which were considered to be difficulties associated with living in residence. Negative correlations were obtained between convenience and total time spent cooking per day and having learned to be autonomous in the kitchen. For male, the perception of eating well, having a varied diet, and maintaining weight were negatively correlated to convenience. For female, the correlation between convenience and the difficulty of eating enough was significant and positive. Negative correlations were obtained between convenience and fresh vegetables, potatoes, eggs, fresh meat, fresh fish and fresh poultry, herbal tea and alcohol. Positive correlations were obtained between convenience, frozen foods and foods brought from the parents’ home. Findings are discussed from both a health and a family perspective. 相似文献

The factor structure of the Multidimensional Ethics Scale (MES; Reidenbach and Robin: 1988, Journal of Business Ethics
7, 871–879; 1990, Journal of Business Ethics
9, 639–653) was examined for the 8-item short form (N = 328) and the original 30-item pool (N = 260). The objectives of the study were: to verify the dimensionality of the MES; to increase the amount of true cross-scenario
variance through the use of 18 scenarios varying in moral intensity (Jones: 1991, Academy of Management Review
16, 366–395); and, to examine the items for measurement precision using item-response theory (IRT) methods. Results of confirmatory
and exploratory factor analysis failed to conclusively support the hypothesized 3- (short form) or 5-factor (long form) structure;
both instruments were instead dominated by a general factor. Item response theory analyses using Samejima’s (1969, Psychometrika Monograph Supplement
34, (4, Pt. 2)) graded response model revealed that many items in the 30-item pool performed very well, and suggested that a
different collection of items be used to form a short-form version of the MES. Our proposed 10-item instrument includes more
discriminating items than the 8-item version, and has the added advantage of including two items from each of the five ethical
philosophies represented in the original 30-item pool.

This article presents the results of an empirical study that investigated coordination and control within multinational companies over six key aspects of their environmental strategy. Specifically, it first examines the level of centralization of these key issues. Second, it investigates whether there is a positive relation between three variables associated with organizational complexity and the level of centralization of the environmental issues. Statistical analyses of the data obtained from a sample of 98 North American multinationals were conducted. The study's results revealed that most companies have adopted a global environmental standard to govern their worldwide business activities that is supported by strong central controls over both environmental performance evaluation of facilities and decisions regarding the development of environmental programs. Results also revealed that there are limited links between organizational complexity and most aspects of the environmental strategy. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment. 相似文献

There is a shortage of engineers and scientists, in particular, electronic engineers and computer scientists, in Sweden. This shortage is argued to be one factor behind the structural weakness of Swedish industry in the 'high tech' area. The conventional explanation of the imbalance in the supply and demand for electronic engineers and computer scientists is focused on the incentives for the individual to demand higher education. These are argued to be low due to the relatively equal income distribution in Sweden and to high taxation. We find that the evidence given in support of this specification of the institutional problem is not convincing. Instead, we specify the institutional problem as having been a lack of opportunities to study electronics and computer science. With recent institutional changes in higher education, this problem is currently being tackled. Looking ahead, we see a new institutional problem emerging with a distinct gender bias. In order to increase the number of degrees awarded in electronics and computer science further, we will need to raise the interest of women in science and technology studies. This requires major institutional changes with regard to both the form and content of the educational programmes. 相似文献

Abstract. We discuss statistical inference problems associated with identification and testability in econometrics. We consider inference in non-parametric models and weakly identified structural models (weak instruments). We point out that many ill‐defined statistical problems, such as non‐testable hypotheses, occur in these areas and are typically associated with asymptotic approximations. In non‐parametric models, such problems include testing moments and inference under heteroscedasticity or serial dependence of unknown form. For weakly identified structural models, difficulties are typically associated with improper pivots, and we review recent developments aimed at proposing more reliable procedures, including alternative proposed statistics, bounds, projection, split‐sampling, conditioning, Monte Carlo tests.

This paper is a synthesis of the July 2005 Development Report published by the Development Bank of Southern Africa, Human Sciences Research Council and United Nations Development Programme (DBSA, HSRC and UNDP). The Report asks why, if the origins of economic dualism are rooted in the cheap, forced, migrant labour introduced by the mining industry and reinforced during apartheid, does dualism persist under democracy when all the relevant laws and many of the practices of the past have been abolished? The breakdown of apartheid did not immediately translate into improved material conditions for the majority of South Africans: 300 years of colonialism and 50 of internal colonialism had hard-wired a duality into the system. Two worlds, which may be conceptualised as the first and second economies, coexisted: a globally integrated world of production, exchange and consumption, and a constrained world of informality, poverty and marginalisation. This synthesis sheds light on the origin and nature of the ‘second economy’ metaphor, and suggests solutions. 相似文献

An arbitrary number of units of a good is sold to two bidders through a discriminatory auction. The bidders are homogeneous ex ante and their demand functions are two‐step functions that depend on a single parameter. We characterize the symmetric Bayesian equilibrium and prove its existence and uniqueness. We compare this equilibrium with the equilibrium of the multiunit Vickrey auction and with the equilibria of the single‐unit first price and second price auctions. We examine the consequences of bundling all units into one package. We study the impacts that variations of the “relative” supply have on the equilibrium, on the bidders' average payoffs per unit, and on the efficiency of the equilibrium allocation. 相似文献

Historically, trading volume reported for NASDAQ stocks has been overstated vis‐à‐vis New York Stock Exchange (NYSE) stocks, both because of the dealer's participation in trades as a market maker and because of interdealer trading. Beginning in 1997, the Securities and Exchange Commission changed order‐handling rules and trade‐reporting rules, which may have reduced or eliminated the overstatement of NASDAQ trading. We examine trading volumes of firms changing from NASDAQ to the NYSE since 1997 and document that reported trading volume for NASDAQ stocks continues to be overstated. Moreover, the degree of overstatement is much larger for firms with high trading volume. 相似文献
