Since I do not disagree with the line of argument taken by Kramer and the distinctions he draws between the different ways rules can be ‘mind-independent’, my comments focus on some of the complexities involved in the application of his distinctions. I suggest that law, properly understood as a system of rules/conventions is both existentially and observationally weakly mind independent, but nonetheless objective.

Dogs have a remarkable skill to use human-given cues in object-choice tasks, but little is known to what extent their closest wild-living relative, the wolf can achieve this performance. In Study 1, we compared wolf and dog pups hand-reared individually and pet dogs of the same age in their readiness to form eye-contact with a human experimenter in an object-choice task and to follow her pointing gesture. The results showed that dogs already at 4 months of age use momentary distal pointing to find hidden food even without intensive early socialization. Wolf pups, on the contrary, do not attend to this subtle pointing. Accordingly in Studies 2 and 3, these wolves were tested longitudinally with this and four other (easier) human-given cues. This revealed that wolves socialized at a comparable level to dogs are able to use simple human-given cues spontaneously if the human’s hand is close to the baited container (e.g. touching, proximal pointing). Study 4 showed that wolves can follow also momentary distal pointing similarly to dogs if they have received extensive formal training. Comparing the wolves to naïve pet dogs of the same age revealed that during several months of formal training wolves can reach the level of dogs in their success of following momentary distal pointing in parallel with improving their readiness to form eye-contact with a human experimenter. We assume that the high variability in the wolves’ communicative behaviour might have provided a basis for selection during the course of domestication of the dog.  相似文献

The heritability of human behavior can be estimated through studies comparing MZ and DZ twins and through adoption studies. Meta-analyses have estimated the heritability of intelligence, mental chronometric performance, language ability, anxiety disorders, major depression, antisocial behavior, problem drinking, and smoking. This article presents the aggregation and analysis of these meta-analyses, which included a total of over four hundred samples. The results of the aggregation suggest that about 41% of human behavior is genetically influenced, a percentage that may have evolutionary value. Some significant moderators were found in more than one meta-analysis, including greater heritability (a) in more disordered levels of a behavior for performance on a language-ability test, antisocial behavior, and smoking and (b) in females for antisocial behavior and smoking initiation. The moderator findings raise questions about what might explain the identified differences in level of heritability.  相似文献

This article explores the role of organizational professionals in the evolutionary development of business. Such professionals are currently defined in the fields of human resources development, organizational development and human performance improvement as executive and strategic coaches, training professionals and consultants. Their work seeks to improve the human systems on which organizational processes depend. This article explores (a) areas of convergence and divergence among these fields; (b) how these professions might contribute to the conscious evolution of humane, sustainable and viable organizational cultures; and (c) the challenges and issues these professions must effectively address.  相似文献

One of the most threatening problems the world faces is the growing poverty crisis and the related human rights inequalities and the spread of diseases in underprivileged areas. Human rights and relief organizations try hard to contain the devastation of these interconnected difficulties. What is the role of the biomedical scientist in this endeavor? The challenges that biomedical scientists face in their research lead us to question whether scientists can go beyond the time‐consuming realm of experimental investigation and engage the issues of society in a more public way. I suggest how the scientist's role can be expanded in our complex and precarious world, introducing the idea of the modern biomedical researcher as scientist, scholar‐philosopher, and statesman for the scientific community and the larger human rights community. I provide examples of where the scientist can interface with human rights organizations, medical doctors, political and civic leaders, and the science‐religion dialogue. My argument reveals the emerging role of the biomedical scientist as one of public service in addition to and beyond the realm of the experimental investigator. This role, however, is formidable, and I list some of the obstacles it entails.  相似文献

Walking in an environment of moving ground texture   总被引:1,自引:0,他引:1  
The visual control of global body movements has mainly been studied in terms of the maintenance of balance. The present experiment examined the effect of moving visual surroundings on the speed of locomotion. A virtually boundless optical environment was generated by the projection of a dotted texture on the ground that was reflected on large vertical mirrors fixed along the walls of the room. Subjects' head velocity was recorded over a walking path of about 10 m along the projection surface. In the experimental sessions, the texture was animated and moved at different speeds in the same direction as the subject or in the opposite direction. In the control condition, the projected texture remained motionless and therefore appeared to pass by at the subjects' walking speed. The subjects' task was to maintain a constant walking speed as far as possible over the different conditions. Changes in walking speed give indications of how the processing of optical flow modulates locomotor activity.  相似文献

We explore the application of a wide range of sensory stimulation technologies to the area of sleep and dream engineering. We begin by emphasizing the causal role of the body in dream generation, and describe a circuitry between the sleeping body and the dreaming mind. We suggest that nearly any sensory stimuli has potential for modulating experience in sleep. Considering other areas that might afford tools for engineering sensory content in simulated worlds, we turn to Virtual Reality (VR). We outline a collection of relevant VR technologies, including devices engineered to stimulate haptic, temperature, vestibular, olfactory, and auditory sensations. We believe these technologies, which have been developed for high mobility and low cost, can be translated to the field of dream engineering. We close by discussing possible future directions in this field and the ethics of a world in which targeted dream direction and sleep manipulation are feasible.  相似文献

IntroductionTeachers tend to develop negative expectations and behaviours towards students coming from low socioeconomic backgrounds.ObjectiveThe objective of this study was to test the influence of teacher political orientation, as well as their attachment to power and universalism values, on their predictions of academic success towards students from different socioeconomic backgrounds.MethodEighty-eight high school teachers (Mage = 38.04 years; 44.3% men) responded to a questionnaire of political ideology and values, as well as to a questionnaire evaluating their prediction of success towards male high school students from different socioeconomic backgrounds.ResultsTeachers predicted a better academic success for students coming from a high socioeconomic background. Despite relatively small effect size, political ideology, as well as attachment to power and universalism values, predicted the bias of judgment.ConclusionTaking into consideration teachers’ ideology and values would deepen understanding of processes underlying expectations development.  相似文献

The effective enforcement of traffic laws is critical for improved road safety outcomes. Decisions to follow traffic rules and pay fines are influenced by formal institutions (e.g. laws, court summons, and fines) as well as informal institutions (e.g. norms and aspects of culture). Formal and informal institutions create incentives that should be designed to steer individuals’ behaviour towards desired outcomes. Unfortunately, there is no reason to believe that the institutions to deal with traffic violations in South Africa currently create effective incentives. This paper discusses the findings of a controlled laboratory experiment, conducted with a sample of university students, that tested the efficacy of different financial incentives that may influence the payment of traffic fines. An early payment discount was compared to a late payment penalty (used in other countries, for example, some states in the USA), and to the absence of any incentives. Furthermore, we examined whether the willingness to settle fines is sensitive to the likelihood of detection by the authorities. We found that introducing financial incentives significantly increases voluntary payment of fines, irrespective of whether immediate payment is encouraged with a discount or late payment is discouraged with a surcharge. In addition, subjects are more sensitive to the likelihood of detection when financial incentives are present.  相似文献

Human action recognition in videos is a tough task due to the complex background, geometrical transformation and an enormous volume of data. Hence, to address these issues, an effective algorithm is developed, which can identify human action in videos using a single decisive pose. To achieve the task, a decisive pose is extracted using optical flow, and further, feature extraction is done via a two-fold transformation of wavelet. The two-fold transformation is done via Gabor Wavelet Transform (GWT) and Ridgelet Transform (RT). The GWT produces a feature vector by calculating first-order statistics values of different scale and orientations of an input pose, which have robustness against translation, scaling and rotation. The orientation-dependent shape characteristics of human action are computed using RT. The fusion of these features gives a robust unified algorithm. The effectiveness of the algorithm is measured on four publicly datasets i.e. KTH, Weizmann, Ballet Movement, and UT Interaction and accuracy reported on these datasets are 96.66%, 96%, 92.75% and 100%, respectively. The comparison of accuracies with similar state-of-the-arts shows superior performance.  相似文献
