This article begins from the awareness that in a world of affluence, millions are hungry. It addresses the question as to whether this is merely an economic issue or whether it also poses an ethical and theological dilemma, considering ways in which the situation we are living in challenges our faith in the transformation of bread and wine into the body and blood of Christ. It asks how, in the situation as it is, there is any possibility of believing in such a transformation. Finally it questions whether there is any relationship between hope for the transformation of hunger amidst affluence and belief in the transformation of bread into the body of Christ, and outlines a transformative eucharistic vision for the global Christian Church. 相似文献

The role of Amartya Sen's early work on famine notwithstanding, food security is generally seen as but one capability among many for scholars writing in development ethics. The early literature on the ethics of hunger is summarized to show how Sen's Poverty and Famines was written in response to debates of past decades, and a brief discussion of food security as a capability follows. However, Sen's characterization of smallholder food security also supports the development of agency in both a political and an economic sense. Economic agency is discussed and tied to longstanding literatures on the moral significance of farming within political economy. Finally, while the newly emergent literature on food sovereignty includes many themes, it is shown to be re-articulating arguments that stress smallholder's economic agency as a development goal. This pattern of argument thus provides a way to reconcile at least some of the claims being advanced under the banner of food sovereignty with the human development approach, while also restoring food ethics to a more central place in the overall discourse of development ethics. 相似文献

Fundamental to adaptive behaviour is the ability to select environmental objects that best satisfy current needs and preferences. Here we investigated whether temporary changes in food preference influence visual selective attention. To this end, we exploited the fact that when a food is eaten to satiety its motivational value and perceived pleasantness decrease relative to other foods not eaten in the meal, an effect termed sensory-specific satiety. A total of 26 hungry participants were fed until sated with one of two palatable foods. Before and after selective satiation, participants rated the pleasantness of the two foods and then viewed the same as stimuli on a computer screen while attention was assessed by a visual probe task. Results showed that the attentional bias for the food eaten decreased markedly from pre- to postsatiety, along with the subjective pleasantness for that food. By contrast, subjective pleasantness and attentional bias for the food not eaten did not show any such decrease. These findings suggest that the allocation of visual selective attention is flexibly and rapidly adjusted to reflect temporary shift in relative preference for different foods. 相似文献

The aim of this study was to examine whether fan engagement could be predicted by the motivational dimensions of sport consumption. A sample of 806 football sport fans (African = 85%, male = 67.4%, part of an organised supporters club = 57.6%) were participants. They completed the Fan Engagement Scale (FES), the Motivation Scale for Sport Consumption (MSSC) and a biographical questionnaire. Structural equation modelling was applied to evaluate the postulated regressive paths between the motivational dimensions for sports consumption and fan engagement. The motivational dimensions for sport consumption were clustered into personal and game-related factors. Both these clusters of factors were predictive of fan engagement. Customer engagement (CE) theory appears to explain the findings. 相似文献

This paper explores the impact that recent transformations in digital music technology (e.g. the increasing popularity of legal streaming platforms) have had on the consumer experience. Following 35 in‐depth qualitative interviews, we have identified four key segments of contemporary music consumers (steadfast pirates, ex‐downloaders, mixed tapes and the old schoolers [the disengaged]) based on a continuum of their preference for illegal music piracy. Examining key themes (e.g. morality, format, value and identity investment) to distinguish each segment, we contribute to a fragmented music piracy literature in particular through the identification of the “ex‐downloaders” and “mixed tape” segments. Previous literature has tended to frame music piracy in very simplistic terms, failing to acknowledge a large number of consumers who are conflicted about their actions and rationalise their piracy in complicated and inconsistent ways related to the broader industry and their own sense of identity as a music consumer. Additionally, the discussion of the ex‐downloader segment provides significant evidence that for a large number of consumers, a policy of participation, in the shape of providing superior alternatives for legal digital music consumption, can be much more beneficial in tackling the problem of piracy than previous strategies of policing and coercion. Managerial and future research implications are discussed. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Previous research has shown that focus of attention affects movement economy in endurance tasks. This experimental study was designed to take a closer look at how focusing attention on special characteristics of endurance cycling actions can influence metabolic energy costs. Twenty-five trained cyclists completed 4 × 6 min time trials at submaximal intensity on a cycling ergometer. For each of the four time trials, they were instructed to adopt a different focus of attention: (1) circular pedaling, (2) force production of quad muscles, (3) head position, (4) stimuli in a cycling video. The order of conditions was counterbalanced. The main dependent measure was movement economy (i.e., oxygen consumption at a given workload). The results show that a focus on the circular pedaling action leads to reduced economy than a focus on the video (p = 0.001). Focusing on smooth and circular pedaling includes a continuous monitoring of the cycling action, which could disturb the rhythmical nature of movement execution, thereby leading to detriments in movement economy. 相似文献
