Abstract The publication of Rachel Carson's Silent Spring, a compelling blend of stories, natural history, human values, and biological facts, in 1962 was instrumental in launching the modern environmental movement. We consider Carson's attitude toward animals in Silent Spring and in her other writings. Carson favored responsible stewardship and was more of an animal welfarist and environmentalist/conservation biologist who privileged ecosystems and species than an animal activist who privileged individuals, and she did not advocate an animal‐rights agenda. There is clear tension in Carson's writings. Often she seems troubled by attempting to come across as a moderate and practical scientist, and some of her words, when considered out of context, could lead one to label her as an animal‐rightist. While some of Carson's writing favors human‐centered interests, she did not believe that only humans counted. Her warnings about silent springs must be taken seriously, perhaps even more seriously than when they were penned more than four decades ago. Carson was a passionate and extremely influential activist and if a world of persons like her were in charge of our global environmental policies, we and our fellow animals would be in much better shape than we currently are. 相似文献

There are sufficient reasons to conclude that virtual education is not just hype. There are, among others, economic motivations such as bringing one learning module to a larger audience of learners, and pragmatic reasons such as achieving flexibility in time and space for learning, which is especially important for adult learners. However, from a pedagogic point of view there are some doubts. Current technologies meant for learning and working in teams are often designed for functional collaboration (e.g., sharing documents, communicating), but fail to support learning, understanding and team forming (e.g., carrying out pedagogically adequate tasks, understanding each other's work and group dynamic processes) in virtual teams. In order to understand virtual teams, we need to know how we can study learning and understanding in virtual teams. Interesting research questions are: Which concepts are important in understanding virtual teams? How can we measure those concepts, and in what type of setting (e.g., experimental study, case study)? The aim of this special issue is to provide and discuss concepts and pragmatic insights in research on learning and understanding in virtual teams. The aim of this article is to set the stage for those articles. 相似文献

This article argues that there is no sound basis for thinking that we have a general and strong duty to rectify disparities of wealth around the world, apart from the special case where some become wealthy by theft or fraud. The nearest thing we have to a rational morality for all has to be built on the interests of all, and they include substantial freedoms, but not substantial entitlements to others’ assistance. It is also pointed out that the situation of the world’s poor is not that of victims of disasters, but simply of less-developed technology, which can be repaired by full and free trade relations with others. The true savior of the world’s poor is the businessman, not the missionary. What we do need to do is strike down barriers to commerce, rather than requisition “aid.” 相似文献

Contextualist moral philosophers criticise hands-off liberal theories of justice for abstracting from the cultural context in which people make choices. Will Kymlicka and Joseph Carens, for example, demonstrate that these theories are disadvantageous to cultural minorities who want to pursue their own way of life. I argue that Pierre Bourdieu's critique of moral reason radicalises contextualist moral philosophy by giving it a sociological turn. In Bourdieu's view it is not enough to provide marginalised groups or subgroups with equal access to public institutions and specific cultural rights—in some cases this may in fact be detrimental. He contends that scientists, politicians and other intellectuals have a duty to take seriously the social presuppositions of free deliberate choice and public opinion and to support cultural minorities with instruments to liberate themselves from their often precarious situation. 相似文献

Selective attention to relevant targets has been shown to depend on the availability of working memory (WM). Under conditions of high WM load, processing of irrelevant distractors is enhanced. Here we showed that this detrimental effect of WM load on selective attention efficiency is reversed when the task requires global- rather than local-level processing. Participants were asked to attend to either the local or the global level of a hierarchical Navon stimulus while keeping either a low or a high load in WM. In line with previous findings, during attention to the local level, distractors at the global level produced more interference under high than under low WM load. By contrast, loading WM had the opposite effect of improving selective attention during attention to the global level. The findings demonstrate that the impact of WM load on selective attention is not invariant, but rather is dependent on the level of the to-be-attended information. 相似文献

The relationship between self‐regulatory capacities and self‐esteem as well as well‐being is examined by a mediation model that views self‐regulation as promoting the development of identity achievement which, in turn, is expected to be associated with well‐being. Among secondary school students (Study 1) identity achievement mediated the association between the self‐regulatory capacity of attention control and self‐esteem. In Study 2 (university students), the mediational effect of identity achievement was found for the relationship between the self‐regulatory capacity of action control and well‐being. Explicit motives moderated this association. In sum, a firm identity enhances well‐being by lending a sense of continuity to one's life. However, explicit motives have a substitution effect by giving direction to life when lacking firm identity commitments. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

This paper attempts to systematically characterize critical reactions in argumentative discourse, such as objections, critical
questions, rebuttals, refutations, counterarguments, and fallacy charges, in order to contribute to the dialogical approach
to argumentation. We shall make use of four parameters to characterize distinct types of critical reaction. First, a critical
reaction has a focus, for example on the standpoint, or on another part of an argument. Second, critical reactions appeal to some kind of norm, argumentative or other. Third, they each have a particular illocutionary force, which may include that of giving strategic advice to the other. Fourth, a critical reaction occurs at a particular level of dialogue (the ground level or some meta-level). The concepts here developed shall be applied to discussions of critical
reactions by Aristotle and by some contemporary authors. 相似文献

In Gibb’s theory of moral development Piagetian ideas concerning egocentrism play an important role. Based on these ideas Gibbs offers a detailed analysis of transitions in moral development. However, Gibbs still fails to utilize the full potential offered by Piaget’s equilibration theory, because he does not generalize the idea of overcoming egocentrism, as an important mechanism, to all stage transitions. Gibbs seeks a non-relativistic theoretical/ethical justification for his claims about moral development in a difficult to substantiate notion of an underlying reality. Moreover, such objectivist claims are difficult to reconcile with his endorsement of Piaget’s constructivism.Following Piaget’s equilibration theory development can be seen as the march to an ever widening perspective, possible through reflecting abstraction, and implying overcoming egocentric biases that recur at all levels of development. Assuming the widest level in the case of moral development is the moral point of view, an impartial procedure that should guarantee that everybody involved can freely agree as the result of considering arguments reflecting all viewpoints, fits in with a tradition in ethics from Kant, to Rawls, to Habermas which takes the moral point of view as the ultimate moral principle. These so called ‘Procedural Ethics’ theories are not relativistic, but not objectivist either, because they ultimately depend on the characteristics of the procedure. 相似文献

This study was an investigation of awareness, cognitions, and psychosocial and educational needs related to genetic counseling
and testing among Latinas and non-Latina whites at increased risk for having a BRCA1/2 mutation. Sixty-three Latina and eighty-four non-Latina white women completed telephone surveys employing a mixture of quantitative
and qualitative questions assessing awareness, benefits, risks, barriers, and genetic counseling communication preferences
regarding BRCA1/2 testing. Among participants who had not previously had genetic counseling/testing, 56.9% of Latinas (29/51) and 34.8% of
non-Latina white participants (24/69) were unaware of the availability of BRCA1/2 testing. In multivariate logistic regression analysis, Latina ethnicity was the only statistically significant independent
factor associated with lack of awareness (OR = 0.42; 95% CI = 0.19–0.35). No appreciable differences were noted between ethnic
groups regarding perceived benefits of BRCA1/2 testing or desired genetic counseling topics. These findings underscore the importance of increasing awareness of cancer
genetic counseling and genetic testing among both Latina and non-Latina white populations. 相似文献

A two-mode clustering method to capture the nature of the dominant interaction pattern in large profile data matrices 总被引:1,自引:0,他引:1
Profile data abound in a broad range of research settings. Often it is of considerable theoretical importance to address specific structural questions with regard to the major pattern as included in such data. A key challenge in this regard pertains to identifying which type of interaction (double ordinal, mixed ordinal/disordinal, double disordinal) most adequately fits the major pattern in a profile data set at hand. In the present article a novel methodology is proposed to deal with this challenge. This methodology is based on constrained and unconstrained versions of a recently introduced 2-mode clustering model, the real-valued hierarchical classes model. The methodology is illustrated using empirical Person × Situation profile data on altruism. 相似文献
