David Lea 《Ethical Theory and Moral Practice》2008,11(1):37-60
In this paper we begin with a reference to the work of Hernando de Soto The Mystery of Capital: Why Capitalism Triumphs in the West and Fails Everywhere Else, and his characterization of the Western institution of formal property . We note the linkages that he sees between the institution
and successful capitalist enterprise. Therefore, given the appropriateness of his analysis, it would appear to be worthwhile
for developing and less developed countries to adjust their systems of ownership to conform more closely to the Western system
of formal property. However, we go on to point out that property relationships within the Western system have become subject
to redefinition through the expansion of Intellectual Property (IP) rights in ways that ultimately work to the disadvantage
of the developing and less developed countries. We point out that this restructuring has been given global application through
the implementation of the TRIPS agreement by the WTO. In the final section of the paper I suggest ways in which IP rights
and relevant institutions can be reformed in order to avoid the disadvantages to the developing and less developed countries.

In order to rebut G. E. Moore’s open question argument, ethical naturalists adopt a theory of direct reference for our moral
terms. T. Horgan and M. Timmons have argued that this theory cannot be applied to moral terms, on the ground that it clashes
with competent speakers’ linguistic intuitions. While Putnam’s Twin Earth thought experiment shows that our linguistic intuitions
confirm the theory of direct reference, as applied to ‘water’, Horgan and Timmons devise a parallel thought experiment about
moral terms, in order to show that this theory runs against our linguistic intuitions about such terms. My claim is that the
Horgan–Timmons argument does not work. I concede that their thought experiment is a good way to test the applicability of
the theory of direct reference to moral terms, and argue that the upshot of their experiment is not what they claim it is:
our linguistic intuitions about Moral Twin Earth are parallel to, not different from, our intuitions about Twin Earth.

Sub-Saharan Africa bears the brunt of the HIV epidemic, which is fueled by the many ethical, social, and political complexities
that make up Africa. In turn, the pandemic has also caused many ethical, social, and political complexities that Africa now
grapples with. Being infected with HIV is highly complex and challenging.
Regrettably, gender inequality is still pervasive in Africa. The response by African leaders to the pandemic has been, on
the whole, shamefully lethargic.
For Africa to win its war against HIV/AIDS, a paradigm shift is required from the perspective of its socio-political context.
What is called for is positive political will that will address all aspects of the social determinants of AIDS. What is also
required is that Ubuntu is embraced meaningfully. 相似文献

Recent work on captive flying squirrels has demonstrated a novel degree of flexibility in the use of different orientation cues. In the present study, we examine to what extent this flexibility is present in a free-ranging population of another tree squirrel species, the fox squirrel. We trained squirrels to a rewarded location within a square array of four feeders and then tested them on transformations of the array that either pitted two cue types against one cue type, the majority tests, or all cue types against each other, the forced-hierarchy test. In Experiment 1, squirrels reoriented to the two-cue-type location in all majority tests and to the location indicated by the visual features of the feeders in the forced-hierarchy test. This preference for visual features runs contrary to previous studies that report the use of spatial cues over visual features in food-storing species. In Experiments 2-5 we tested squirrels with different trial orders (Experiments 2 and 3), a different apparatus (Experiment 4) and at different times of the year (Experiment 5) to determine why these squirrels had chosen to orient using visual features in the first experiment. Like captive flying squirrels, free-ranging fox squirrels showed a large degree of flexibility in their use of cues. Furthermore, their cue use appeared to be sensitive both to changes in the test apparatus and the season in which we tested. Altogether our results suggest that the study of free-ranging animals over a variety of conditions is necessary for understanding spatial cognition. 相似文献

Classification of dog barks: a machine learning approach 总被引:1,自引:0,他引:1
In this study we analyzed the possible context-specific and individual-specific features of dog barks using a new machine-learning algorithm. A pool containing more than 6,000 barks, which were recorded in six different communicative situations was used as the sound sample. The algorithm's task was to learn which acoustic features of the barks, which were recorded in different contexts and from different individuals, could be distinguished from another. The program conducted this task by analyzing barks emitted in previously identified contexts by identified dogs. After the best feature set had been obtained (with which the highest identification rate was achieved), the efficiency of the algorithm was tested in a classification task in which unknown barks were analyzed. The recognition rates we found were highly above chance level: the algorithm could categorize the barks according to their recorded situation with an efficiency of 43% and with an efficiency of 52% of the barking individuals. These findings suggest that dog barks have context-specific and individual-specific acoustic features. In our opinion, this machine learning method may provide an efficient tool for analyzing acoustic data in various behavioral studies. 相似文献

Orientation perception in rhesus monkeys (<Emphasis Type="Italic">Macaca mulatta</Emphasis>) 总被引:1,自引:1,他引:0
Wakita M 《Animal cognition》2008,11(3):535-545
It was previously demonstrated that monkeys divide the orientation continuum into cardinal and oblique categories. However, it is still unclear how monkeys perceive within-category orientations. To better understand monkeys' perception of orientation, two experiments were conducted using five monkeys. In experiment 1, they were trained to identify either one cardinal or one oblique target orientation out of six orientations. The results showed that they readily identified the cardinal target whether it was oriented horizontally or vertically. However, a longer training period was needed to identify the oblique target orientation regardless of its degree and direction of tilt. In experiment 2, the same monkeys were trained to identify two-oblique target orientations out of six orientations. These orientations were paired, either sharing the degree of tilt, direction of tilt, or neither property. The results showed that the monkeys readily identified oblique orientations when they had either the same degree or direction of tilt. However, when the target orientations had neither the same degree nor direction of tilt, the animals had difficulty in identifying them. In summary, horizontal and vertical orientations are individually processed, indicating that monkeys do not have a category for cardinal orientation, but they may recognize cardinal orientations as non-obliques. In addition, monkeys efficiently abstract either the degree or the direction of tilt from oblique orientations, but they have difficulty combining these features to identify an oblique orientation. Thus, not all orientations within the oblique category are equally perceived. 相似文献

Are ants sensitive to the geometry of tunnel bifurcation? 总被引:1,自引:0,他引:1
The ability to orient and navigate in space is essential for all animals whose home range is organized around a central point. Because of their small home range compared to vertebrates, central place foraging insects such as ants have for a long time provided a choice model for the study of orientation mechanisms. In many ant species, the movement of individuals on their colony home range is achieved essentially collectively, on the chemical trails laid down by their nest mates. In the initial stage of food recruitment, these trails can cross each other and thus form a network of interconnected paths in which ants have to orient. Previous simulation studies have shown that ants can find the shortest path between their nest and a food source in such a network only if there is a bias in the branch they choose when they reach an asymmetrical bifurcation. In this paper, we studied the choice of ants when facing either a symmetrical or an asymmetrical bifurcation between two tunnels. Ants were tested either on their way to a food source or when coming back to their nest, and either in the presence or in the absence of a chemical trail. Overall, our results show that the choice of an ant at a tunnel bifurcation depends more on the presence/absence of a trail pheromone than on the geometry of the bifurcation itself. 相似文献

A moratorium on cyborgs: Computation,cognition, and commerce 总被引:1,自引:0,他引:1
By examining the contingent alliance that has emerged between the computational theory of mind and cyborg theory, we discern some questionable ways in which the literalization of technological metaphors and the over-extension of the “computational” have functioned, not only to influence conceptions of cognition, but also by becoming normative perspectives on how minds and bodies should be transformed, such that they can capitalize on technology’s capacity to enhance cognition and thus amend our sense of what it is to be “human”. We consider “a moratorium on cyborg discourse” as a way of focusing the conceptual and social–political problems posed by this alliance. 相似文献

Human enhancement, in which nanotechnology is expected to play a major role, continues to be a highly contentious ethical
debate, with experts on both sides calling it the single most important issue facing science and society in this brave, new
century. This paper is a broad introduction to the symposium herein that explores a range of perspectives related to that
debate. We will discuss what human enhancement is and its apparent contrast to therapy; and we will begin to tease apart the
myriad intertwined issues that arise in the debate: (1) freedom & autonomy, (2) health & safety, (3) fairness & equity, (4)
societal disruption, and (5) human dignity.

Risk analysis as a regulatory driver has now become firmly entrenched in public health and environmental protection. Risk
analysis at any level essentially has to accommodate two gut feelings of the constituency: whether society should be risk-prone
or risk averse, and whether government and its institutions can be trusted to make the necessary decisions with a high or
a low degree of discretion. The precautionary principle (or rejection thereof) arguably is the ultimate reflection of the
promotion of risk to a societal value. There is no doubt that especially amongst the representatives of the Member States
(as opposed to the officials at the European Commission), public (pre)caution with respect to the long-term environmental
and public health implications of gene technology influenced the reluctance to allow marketing of GM foods and feeds until
a strict regulatory regime had been rolled out. Industry would argue that the delay in regulation, as well as the eventual
regime was of such a nature as to stifle the technology. This contribution reviews a number of features of standard EU risk
analysis decisions, so as to assess its current propensity towards smothering rather than smoothing the introduction of new
technology. The current development of a regulatory framework for nanotechnology serves as a case study.
