A number of studies have shown that dogs are sensitive to a human’s perspective, but it remains unclear whether they use an egocentric strategy to assess what humans perceive. We investigated whether dogs know what a human can see and hear, even when the dogs themselves are unable to see the human. Dogs faced a task in which forbidden food was placed in a tunnel that they could retrieve by using their paw. Whereas the dogs could not see the experimenter during their food retrieval attempts, the experimenter could potentially see the dog’s paw. In the first experiment, dogs could choose between an opaque and a transparent side of the tunnel, and in the second experiment, they could choose between a silent and a noisy approach to the tunnel. The results showed that dogs preferred a silent approach to forbidden food but they did not hide their approach when they could not see a human present. We conclude that dogs probably rely on what they themselves can perceive when they assess what the human can see and hear.  相似文献

This paper focuses on the contribution of meta-regulation in responding to the regulatory needs of a field beset by significant uncertainties concerning risks, benefits and development trajectories and characterised by fast development. Meta-regulation allows regulators to address problems when they lack the resources or information needed to develop sound “discretion-limiting rules”; meta-regulators exploit the information advantages of those actors to be regulated by leveraging them into the task of regulating itself. The contribution of meta-regulation to the governance of nanotechnologies is assessed in terms of responsibilisation. Responsibilisation is regarded as a pre -requisite for regulatory actors to internalise social values (such as consumer safety and occupational health) and to ensure that these values are built into regulatory practice. In order to explore the potential of responsibilisation, the Code of Conduct for Responsible Nanosciences and Nanotechnologies Research launched by the European Commission in 2008 is evaluated. The Code is a good case of meta-regulation that aims to steer the self-regulation of nanotechnological business and research organisations. The paper concludes that, while efforts were made on the part of meta-regulators and self-regulators to contribute to responsibilisation, important opportunities for responsibilisation such as dissemination and promotion of the Code, trust-building activities, and failure to provide rewards, incentives and stakeholder guidance were not taken up. In order to foster responsibilisation within the meta-regulatory instrument of the EC Code, a number of crucial activities to be undertaken by meta-regulators are recommended.  相似文献

At workplaces where nanomaterials are produced or used, risk assessment and risk management are extremely difficult tasks since there is still limited evidence about the risks of nanomaterials. Measurement methods for nanoparticles are contested and safety standards have not yet been developed properly. To support compliance with the legal obligation of the employer to care for safe workplaces a large number of ‘soft’ regulatory tools have been proposed (e.g. codes of conduct, benchmarks, standards). However, it is not clear whether and under which conditions soft regulation is complied with. This article discusses the potential advantages and drawbacks of soft regulation. It explores compliance issues when exposure measurement devices and other technology-related factors are involved. The exploration of three examples of soft regulation on occupational health and safety (a ministerial recommendation on preliminary exposure benchmarks, a nano-specific guidance of a chemical company and a public–private OHS guideline) shows that the capacity of the regulated parties to comply depends on the availability of appropriate technological devices and methods, technical expertise and other resources. When technological prerequisites are met, compliance is likely to increase.  相似文献

The Quick-Estimation heuristic (QuickEst) was introduced by Hertwig, Hoffrage, and Martignon (1999 Hertwig , R. , Hoffrage , U. , & Martignon , L. (1999) . Quick estimation: Letting the environment do the work . In G. Gigerenzer , P. M. Todd , & the ABC Research Group (Eds.) , Simple heuristics that make us smart (pp. 209234) . New York : Oxford University Press . [Google Scholar]) as a fast and frugal method to generate numerical estimates. The heuristic posits that estimate-relevant knowledge is organised and searched according to ordered reference classes that are based on binary cue values. Two experiments tested two main predictions derived from QuickEst with respect to the memory search and estimation behaviour of human participants. The results provided no evidence that QuickEst is used in numerical estimation processes. As alternative explanation of our findings, we discuss a cyclic sampling mechanism that retrieves information from memory according to their associative strength.  相似文献

People frequently continue an investment despite a negative outcome or sunk cost. Such irrational persistence in a losing course of action has been termed escalation of commitment. Although several explanations of escalation of commitment have been proposed, none of them accounts for all determinants that have been empirically demonstrated. Based on a review of previous research, a conceptualisation is introduced of how escalation of commitment is affected by 4 task dimensions: type and nontransparency of decision goal, nontransparency of sunk costs, time course of sunk costs, and accountability. A more inclusive theory that subsumes escalation of commitment is offered as an alternative that may be developed to account for the effects of the task dimensions.  相似文献

On what model should a modern multi‐cultural democracy work? Spinosa et al. have argued that the political order should be sustained by a set of common values instilled in the citizens, without, however, any common rank order among these values. I argue that the multi‐cultural state should rather conform to what I call the Secular Model, according to which the citizens need not share any basic values at all. On the Secular Model, people individually stick to the existing constitution (only) as long as they each feel that they have good reasons to do so. To be sure, each citizen of a multi‐cultural state does need a feeling of community identity, a ‘we’ ideology, but it is desirable that each individual can have more than one such identity. It is also important that each individual can shift as he or she pleases, from one such identity to another. So this kind of identity should not be moulded by the state, but by various different free associations, independent of the state.  相似文献

This essay gives an interpretation of Heidegger's “What is Metaphysics?” lecture in light of passages from his other writings and lecture courses of the period. This exegetical task is important, for interpreters of “What is Metaphysics?” have been confused by puzzling phrases in the lecture without noticing that Heidegger makes the same points in clearer terms elsewhere. In particular, these interpreters ignore Heidegger's crucial distinction between entities and the being of entities. Since Heidegger's “nothing” is an aspect of being, this difference is at the core of Heidegger's lecture. The present interpretation establishes a conditional conclusion: If the ontological difference makes sense, then we have a sound basis for understanding “What is Metaphysics?” and do not need to read Heidegger as an irrationalist who debunks science or rejects the principle of contradiction. This paper does not give independent justification for the ontological difference.  相似文献

Research on risks and unwanted effects is largely missing in psychotherapy. Using exploratory factor analysis six dimensions of personal therapy situation were identified in a preliminary study, three of them were associated with risky developments during the psychotherapeutic process: (1) (poor) quality of therapeutic relationship, (2) burden caused by psychotherapy, and (3) dependency/isolation. Based on the finding of this study an online survey was performed to examine these three dimensions. Aside from these three factors another variable was associated with risky therapy developments: the online questionnaire also asked for premature terminations of psychotherapy as a consequence of risky conditions for the therapeutic development. Risky conditions were found to be associated with the following variables: (1) the combination of female patient–male therapist, (2) the therapeutic orientation (particularly with the psychodynamic approaches) and (3) the duration of therapy. Fewer humanistic and systemic psychotherapies were found among the high risk-prone group of patients who were at risk in at least three of the four variables which were associated with risky developments. Differences in the findings of the study regarding the four therapeutic orientations stress the importance of an extensive differential indication and a cooperative partnership between patient and therapist, in order to facilitate a positive patient participation towards the choice of therapy method and subsequent successful participation throughout the course of treatment. Further studies should also focus on female patient and male therapist psychotherapies.  相似文献

Moderated mediation effects on attitude toward environmental policy measures of a self‐enhancement vs. self‐transcendence value orientation were examined in two studies. Study 1 (n = 91) showed that for policy measures incurring nontransparent personal costs, influence of value orientation on attitude is fully mediated by environmental concern, whereas for measures incurring transparent personal costs, influence is partially mediated by environmental concern. Study 2 (n = 71) showed that while influence of value orientation on attitude toward eco‐labeled electricity is not mediated by environmental concern, it is fully mediated by reluctance to pay surcharges for eco‐labeled electricity. Value orientation was also shown to moderate influence of reluctance to pay on attitude in that reluctance had an effect only for a self‐enhancement value orientation.  相似文献
