Household food waste is considered to be the largest share of food waste along the food supply chain. Given that its recoverability is also more challenging compared to food waste in other stages of the chain, most studies on household food waste adopt a pre‐emptive approach by aiming to identify and address consumer beliefs, attitudes and actions that are linked to food waste. In scientific literature, household food waste has often been studied in relation to the habit of purchasing discounted food products (DFP). However, findings have been contradictory. Specifically, while some authors found that deal‐prone consumers are usually of lower income and therefore display a wiser and more attentive attitude towards grocery shopping, other authors reported that the purchase of discounted products was usually linked to compulsive shopping, hence resulting in higher food waste quantities at home. Due to these discrepant findings, a definitive answer on the impact of DFP on household food waste does not currently exist in the literature. This paper analyses the correlation between the purchase of DFP and weekly household food waste quantities. To do so, we examine (a) the results of a food waste diary experiment carried out on a representative sample of 385 households in Italy in February 2017, and (b) the results of a 23‐items Computer Assisted Web Interview survey administered to the same householders, in which shopping habits were investigated. Results revealed no evidence of either a positive or negative relationship between the purchase of DFP and household food waste quantities. Frequency of grocery shopping was the only variable found to have a significant impact on household food waste quantities. 相似文献

This paper argues that the socialist episode in East Germany, which constituted a radical experiment in gender equality in the labor market and other instances, has left persistent tracks on gender norms. We focus on one of the most resilient and pervasive gender gaps in modern societies: mathematics. Using the German division as a natural experiment, we show that the underperformance of girls in math is sharply reduced in the regions of the former GDR, in contrast with those of the former FRG. We show that this East–West difference is due to girls’ attitudes, confidence and competitiveness in math, and not to other confounding factors, such as the difference in economic conditions or teaching styles across the former political border. We also provide illustrative evidence that the gender gap in math is smaller in European countries that used to be part of the Soviet bloc, as opposed to the rest of Europe. The lesson is twofold: (1) a large part of the pervasive gender gap in math is due to social stereotypes; (2) institutions can durably modify these stereotypes. 相似文献

Combinative Effects of Innovation Types and Organizational Performance: A Longitudinal Study of Service Organizations 总被引:2,自引:0,他引:2

Innovation research suggests that innovation types have different attributes, determinants, and effects. This study focuses on consequences of adoption of three types of innovation (service, technological process, and administrative process) in service organizations. Its main thesis is that the impact of innovation on organizational performance depends on compositions of innovation types over time. We examine this proposition by analysing innovative activity in a panel of 428 public service organizations in the UK over four years. Our findings suggest that focus on adopting a specific type of innovation every year is detrimental, consistency in adopting the same composition of innovation types over the years has no effect, and divergence from the industry norm in adopting innovation types could possibly be beneficial to organizational performance. We discuss the implications of these findings for theory and research on innovation types. 相似文献

Values and norms as research topics are central theoretical and empirical constructs in communication studies and are also used to substantiate research questions or to interpret results. Despite the relevance of values and norms, a respective debate within the discipline has been neglected so far. It is a challenge to discuss the values and norms of our discipline and to initiate an exchange of the societal relevance of one’s own research. The network “Values and norms as research objects and guiding principles in communication research”, funded by the German Research Foundation (DFG), makes a contribution to this by systematically analyzing values and norms in communication studies and by critically reflecting them. Therefore, the paper proposes to operationalize values and norms as “ought-statements”. Ought-statements either describe a situational state that is explicitly evaluated or address a desirable state. Three elements of an ought-statement are identified, which are coded in a multistage content analysis. The operationalization of norms and values as ought-statements allows not only to examine already known values and norms, but also to assess all possible values and norms, to assess the change of values and norms more validly in long-term studies, and to assess those constructs that are labeled as norms or values by the researchers themselves. 相似文献

In this study, we use data from an induced value choice experiment to compare estimates from mixed logit models in willingness to pay (WTP) space using different parameter distributional assumptions. Specifically, we test differences in WTP estimates when using flexible parameter mixing distributions (i.e. Legendre polynomials, step functions and splines) and conventional parameter distributions (normal and lognormal). Similar WTP estimates are obtained. However, we observe that WTP estimates are statistically different from the induced value when conventional distributions are assumed, but they are not when more flexible distributions are assumed. This suggests that flexible distributions can provide more reliable WTP estimates. 相似文献

The Legacy of Mexico's Agrarian Counter‐Reforms: Reinforcing Social Hierarchies in Calakmul,Campeche

In this paper, we examine how Mexico's 1992 counter‐reforms reinforced social hierarchies between two ‘classes’ of residents within three ejidos in an agricultural frontier in Campeche. We carried out qualitative research with 94 ejidatarios, 92 pobladores and 13 government officials. Our research shows that the reforms cemented the second‐class status of pobladores, as their access to land, natural resources such as firewood and governmental subsidies is now even more contested. Ejidal residents have responded to these tensions by invoking various conceptions of citizenship to press for different forms of justice. Ejidatarios seek to enforce their legal prerogatives by advocating a tiered citizenship, inflected with aspects of ‘market citizenship’, in which pobladores have less access to resources and voice. Pobladores seek inclusion in the ejido via a cultural model of citizenship built around a ‘civil sociality’. Despite this generalization, both groups also selectively move between and combine these citizenship frameworks to advance their claims. 相似文献

The ambition of the school girl to “work in an office” in preference to work in a factory has often been commented on by vocational counsellers and others in touch with girls who are seeking their first jobs. 相似文献

This paper shows that imprecisely stated discounts in brand promotions offered in the form of a low-probability lottery can lead to higher sales (purchase intentions) and consequently profits than equally costly conventional promotions offering a precise discount on the entire stock. Results from two different experimental studies support our findings. For high-probability lottery-like promotions, imprecise discounts lead to a lower performance for the brand than conventional promotions. We attempt to explain the findings by drawing on the behavioral decision theory literature. 相似文献
