What are we doing to our climate? Emissions from fossil fuel burning have raised carbon dioxide concentrations 35 percent higher than in the past millions of years. This increase is warming our planet via the greenhouse effect. What is climate change doing to and for us ? Dry regions are drier and wet ones wetter. Wildfires have increased threefold, hurricanes more violent, floods setting record heights, glaciers melting, and seas rising. Parts of Earth are increasingly uninhabitable. Climate change requires us to act as a global community. Climate justice enjoins emitters to pay the social‐environmental costs of fossil fuel burning. This would expedite green solar, wind, and next‐generation nuclear energy sources. Individuals should conserve resources, waste less food, and eat a plant‐rich diet.  相似文献

Globalization has been the catalyst of world economic development in the past decades. However, the phenomenon has recently been severely challenged by a wave of deglobalization. Within this new trend, the conflict between the United States (US) and China has attracted the attention of scholars from various fields because of the two countries' significance in the world economy. In this study, we focus on the higher education sector, which is highly relevant to globalization, and explore the factors that may affect Chinese college students' attitudes towards US universities, including country image, cultural openness, consumer animosity and perceived quality. In particular, we distinguish between cognitive and affective animosity and test their different impacts on students' attitudes. The results show that students' perception of the US's image positively influences attitudes towards the country's universities thanks to the mediation of perceived quality. Moreover, cultural openness and cognitive animosity are positively related to attitudes, whereas affective animosity exerts a negative impact on attitudes. The implications and limitations of this study are also discussed.  相似文献

Robert Lane is a seasoned critic of American consumer society. His latest book summarizes many of the arguments brought up earlier and contributes new data about developments in income, companionship and happiness in the USA between 1972 and 1994. Lane notes a considerable rise in incomes over these years and claims that companionship and happiness have declined. He attributes this decline to market forces that emphasize money at the expense of intimate bonds, resulting in a weakened capacity to deal with stress.This review challenges two of the book's hypotheses. First, it shows that happiness did not decline in the USA in these years, but was actually quite stable. Second, it mitigates the assertion that companionship has dwindled and notes that money making and companionship are not necessarily antithetical.Still, Lane could be right. Possibly market forces did depress happiness and possibly that loss was offset by improvements in other fields, like increased freedom or better health care, such as better treatment for mental problems. If so, Lane's message is that Americans could have been happier than they ultimately were.  相似文献

When we publish behavioral research, we are not allowed to communicate the thrill, the poetry, or the exhilaration that are outcomes of the discovery process. Yet, these are among our most potent reinforcers. Explicit recognition of the emotional accompaniments to research could help attract students into the experimental analysis of behavior.  相似文献

Three experiments on conditioned suppression in rats examined the extent to which preexposure to the CS, the US, or uncorrelated presentations of both interfere with future conditioning. Experiment 1 suggested that the interference caused by preexposure to the US alone may result from blocking by contextual cues: signaling the US during preexposure attenuated the interference. Experiment 2 demonstrated that signaling the US by another stimulus did not attenuate the interference caused by exposure to uncorrelated presentations of CS and US. Experiment 3 replicated the results of Experiments 1 and 2 and directly compared the magnitude of these deficits. The results of these experiments imply that the effects of exposure to uncorrelated presentations of CS and US are not reducible to the sum of the effects of exposure to CS or US alone.  相似文献

Abstract. Considerations from evolutionary biology lead Michael Ruse, among others, to a naturalistic turn in philosophy. I assess some of the pragmatic and skeptical conclusions concerning ethics, religion, and epistemology that Ruse draws from his evolutionary naturalism. Finally, I argue that there is an essential tension between science and religion which forecloses the possibility of an ultimate reconciliation between the two as they are now understood.  相似文献

In my contribution to the interdisciplinary discussion of Terence Keel's study on the Christian roots of modern racial science, I focus on its philosophical assumptions and implications. My primary concern is to relate the findings of this study to recent appraisals of the philosophical notion of a secularized Western modernity. I raise a twofold question: in what sense can one say that traditional Christianity links intimately to modern racial science, and which historiographical decisions inform the substantiation of such links?  相似文献

Fairness in evaluation processes for women in science and engineering is only one of a set of issues that need to be addressed to reach gender equality. This article uses concepts from Amartya Sen's work on inequality to frame gender issues in science and technology policy. Programs that focus on increasing the number of women in science and engineering careers have not generally addressed a broader set of circumstances that intersect with gender at various economic levels and stages of life. The agendas in research and innovation policies also need to reflect these issues, and fair allocation of resources within both science and technology needs to be on the agenda. Getting women into high-level positions is not enough. Articulating the full research and innovation agendas for women will require broader participatory processes.  相似文献

US Jōdo Shinshū Buddhist songs in the style of Christian hymns—what the community refers to as gāthā—are an integral part of the lived experience of North American Shin Buddhism. Rather than focusing on processes of acculturation, in the following paper I take gāthā seriously as a form of Buddhist practice, asking questions related not to their origins or legitimacy but to their function and purpose. I argue that gāthā function as a mechanism by which shifting ideas, attitudes, and practices become normative within the community. This function becomes apparent when gāthā are placed within their larger ritual context and are performed by the community as a whole. Following on Rappaport's analysis of ritual, gāthā serve as indexical expressions of canonical orientations toward Buddhist practice and teachings.  相似文献

The current study explored body image self-discrepancy as moderator and social comparison as mediator in the effects on women from thin-ideal images in the media. Female undergraduates ( N = 112) with high and low body image self-discrepancy were exposed to advertisements either with thin women (thin ideal) or without thin women (neutral-advertisement control). Exposure to thin-ideal advertisements increased body dissatisfaction, negative mood, and levels of depression and lowered self-esteem. In addition, social comparison processes mediated the relationship between exposure to thin-ideal advertisements and negative self-directed effects. Notably, self-discrepancy moderated this mediation. Women with high levels of body image self-discrepancy were more likely to engage in social comparison from exposure to thin-ideal advertisements, as well as more likely to have those comparison processes induce self-directed negative consequences. This research provides support for an individual difference variable (body image self-discrepancy) that moderates the mediating effect of social comparison from exposure to thin-ideal media.  相似文献

Latent Inhibition (LI) attenuation when a long delay is introduced between acquisition and test phases has been repeatedly observed using aversive conditioning procedures (e.g., Aguado, Symonds, & Hall, 1994). This effect has been used as evidence to support those theories that consider LI to be the result of a retrieval failure. We designed three experiments intended to control for a possible effect of incubation of fear as a possible source of delay-induced attenuated LI. Specifically, we examined the effects of a retention interval between conditioning and testing stages on LI using a 3-stage conditioned emotional response procedure (preexposure, conditioning, and testing). Experiment 1 showed that the LI effect was completely abolished in the delayed testing condition. Experiment 2 evaluated whether a process of fear incubation, developed during the retention interval but obscured by a ceiling effect, produced the attenuation of LI. To this end, we reduced magnitude of conditioning by decreasing US intensity and number of acquisition trials. Experiment 3 directly assessed the relationship between CS–US strength and fear incubation. Experiments 2 and 3 revealed that the apparent reduction of LI after the delay was, at least partially, the result of an incubation effect that is a function of the strength of the CS–US association. The results are discussed with respect to their implications for the different theories of LI.  相似文献

The US Army launched the Global Assessment Tool (GAT) – a 105-item psychometric instrument taken by approximately one million soldiers annually – in October, 2009 in support of a population-wide resilience development initiative known as the Comprehensive Soldier and Family Fitness (CSF2) program. The lead developer of the GAT was Chris Peterson, and his work on this project – along with that of Nansook Park and Colonel Carl Castro – will likely leave an important and indelible mark on not only the Army, but also the field of military psychology. In this paper, we provide more detail on the history and components of the GAT. In addition, we demonstrate the practical utility of the GAT by showing that high-performing soldiers (soldiers who attained Ranger status) have relatively high GAT scores, and that soldiers with behavioral problems generally evidence low GAT scores. We conclude by discussing future directions of GAT methodology and usage in support of research.  相似文献

This paper studies both pecuniary and non-pecuniary factors affecting happiness—an issue that has sparked a great deal of interest in the economic literature. Using an ordered Probit model and the 1998 general social survey (GSS) data, the paper empirically demonstrates the extent to which socioeconomic and demographic variables along with faith and emotionally based factors may determine happiness. The 1998 survey was conducted nearly at the conclusion of one of the longest economic expansion—a high income low inflation era in the US history. However, the findings tend to suggest that the absolute value of nominal income insignificantly, but non-pecuniary elements (faith and emotionally based factors including financial security) significantly determine happiness.

This article examines the pro-trade influence of immigrants using data on state-level exports from the 48 contiguous USA to 28 countries during the year 1993. Immigrants from lesser developed countries are found to exert stronger proportional effects on state-level exports relative to the immigrants from more developed countries. Calculation of absolute immigrant effects at state, regional and national levels also reveal influences of immigrants from developing countries are of greater magnitude; however, results depend on the metric employed to categorize countries as developing or developed. The findings emphasize the importance of immigrants’ connections to business and social networks and allow for an improved understanding of the role that information asymmetries play in fomenting opportunities for immigrants to enhance trade.  相似文献

Evaluative conditioning (EC) refers to a modulation in the liking of a neutral stimulus after it has been paired with an unconditioned stimulus (US). Previous studies have uncovered some of the mechanisms responsible for EC, but many parameters remain unknown. The study addresses two questions: Is the amplitude of EC and the impact of cognitive variables are the same for different types of US? We compared three types of US: shocks, single images and multiple semantically related images. This conditioning occurred while participants maintained a concurrent cognitive load, or not. Our results indicate that all types of US produced a significant EC of similar amplitude. Furthermore, the two cognitive variables had a similar impact across all types of US. Specifically, contingency-awareness was related to the amplitude of EC, particularly in the cognitive load group. Our results illustrate the importance of within study comparisons to assess different parameters on EC.  相似文献

A fairly common view holds that children's risks of negative outcomes associated with family dissolution are generally small or even nonexistent in Scandinavia, and clearly smaller than what is usually found in the United States. This view was empirically examined in a recent large-scale study of 4,127 12–15-year-old children in Norway, of whom 623 had experienced parental divorce and lived in a single-mother family. The somewhat paradoxical pattern of findings was as follows: (a) The negative associations between parental divorce and various outcomes were found to be generally very similar in Norway and the United States in spite of the great differences in family policy and welfare benefits for single mothers (at the macro level); and (b) Mediational effects of family economic resources were in both countries most marked for the academic achievement area, and the predictive power of such variables was quite similar, again in spite of the great differences in absolute level of the economic resources available to single-mother families in the two countries. The results cast some doubt on the value of the absolute economic deprivation perspective in explaining the results, and the many Norwegian welfare benefits do not seem to mitigate the association between divorce and negative outcomes for the children involved. Also policy implications derived from the economic deprivation perspective are questioned. Alternative interpretations of the findings involving relative deprivation and economic resources as a partial proxy for other non-economic factors are briefly discussed.  相似文献

Evaluative conditioning (EC) refers to valence changes of initially neutral stimuli (CSs) through repeated pairings with positive or negative stimuli (USs). The current study is about the moderating role of qualifiers that specify the CS–US relation during these pairings. We show successful EC with pictures of men (CSs) and of liked/disliked animals or landscapes (USs). More importantly, the same pairings resulted in standard and reversed EC effects depending on semantic qualifier of the CS–US relation. CSs loving positive (negative) USs became more positive (negative), while CSs loathing positive (negative) USs became more negative (positive). These data favour a propositional EC account (De Houwer, 2009) over a purely associative account, as they show that it is not only relevant that CS and US are related, but how they are related.  相似文献
