Significant research has been devoted to detecting people in images and videos. In this paper we describe a human de- tection method that augments widely used edge-based fea- tures with texture and color information, providing us with a much richer descriptor set. This augmentation results in an extremely high-dimensional feature space (more than 170,000 dimensions). In such high-dimensional spaces, classical machine learning algorithms such as SVMs are nearly intractable with respect to training. Furthermore, the number of training samples is much (...) smaller than the dimensionality of the feature space, by at least an order of magnitude. Finally, the extraction of features from a densely sampled grid structure leads to a high degree of multicollinearity. To circumvent these data characteristics, we employ Partial Least Squares (PLS) analysis, an effi- cient dimensionality reduction technique, one which pre- serves significant discriminative information, to project the data onto a much lower dimensional subspace (20 dimen- sions, reduced from the original 170,000). Our human de- tection system, employing PLS analysis over the enriched descriptor set, is shown to outperform state-of-the-art tech- niques on three varied datasets including the popular INRIA pedestrian dataset, the low-resolution gray-scale Daim- lerChrysler pedestrian dataset, and the ETHZ pedestrian dataset consisting of full-length videos of crowded scenes.

Eric Olsen argues from the fact that we once existed as fetal individuals to the conclusion that the Standard View of personal identity is mistaken. I shall establish that a similar argument focusing upon dead people opposes Olson’s favored Biological View of personal identity.

In this paper we examine the study of minerals from the Renaissance to the early nineteenth century in the light of the work of Michel Foucault on the history of systems of thought. In spite of a certain number of theoretical problems, Foucault's enterprise opens up to the historian of science a vast terrain for exploration. But this is the place neither for a general exegesis nor for a general criticism of his position; our aim here is the more modest (...) one of taking certain points from Foucault's study,The order of things, and seeing how far they can be extended into an area not explicitly considered in that work.

Two recent papers by Michael Burke bearing upon the persistence of people and commonplace things illustrate the fact that the quest for synchronic ontological economy is likely to encourage a disturbing diachronic proliferation of entities. This discussion argues that Burke's promise of ontological economy is seriously compromised by the fact that his proposed metaphysic does violence to standard intuitions concerning the persistence of people and commonplace things. In effect, Burke would have us achieve synchronic economy (rejection of coincident entities) by (...) postulating strongly counterintuitive transtemporal claims of numerical diversity. The argument is made that the price of Burkean economy is too high. (shrink)

Four non-Cartesian conceptions of a person are considered. I argue tor one of these, a position called animalism. I reject the idea that a (human) person coincides with, but is numerically distinct from, a certain human animal. Coinciding physical beings would both be psychological subjects. I argue that such subjects could not engage in self-reference. Since self-reference (or the capacity tor self-reference) is a necessary condition for being a person, no physical subject coincident with another such subject can be a (...) person. I take all of this to support the view that we (human persons) are identical with human animals. (shrink)

Ethics support staff help others to deal with moral challenges. However, they themselves can also experience moral challenges such as issues regarding (breaching) confidentiality when practicing ethics support. Currently there is no insight in these confidentiality issues and also no professional guidance for dealing with them. To gain insight into moral challenges related to Moral Case Deliberation (MCD), we studied a) beliefs and experiences of MCD facilitators regarding breaching confidentiality, b) considerations for (not) breaching confidentiality, and c) needs for an (...) ethics support tool. Data collection consisted of qualitative research methods: six semi-structured interviews; analyses of a) two recorded MCD sessions, and b) a focus group with MCD facilitators. Findings: MCD facilitators mention different conceptions and interpretations of confidentiality and various moral challenges. Questions concerning confidentiality ultimately cause reflections on roles and responsibilities of facilitators. Needs for ethics support vary from seeking advice to procedural and sometimes normative guidance for MCD facilitators. Education for MCD facilitators should focus on developing a concrete tool that stimulates awareness and reflection(skills). (shrink)

Age-specific mortality rates have been used to illustrate certain aspects of the characteristics of old age. A consideration of the experience of the ageing person in his fifties and early sixties suggests that during this period he comes to recognize death as being an increasingly common characteristic of his age group. Thus the standard procedure for studying old age problems in a sample of people over the age of 65 may miss the period of life when people are making the (...) crucial adjustments to old age and may give a distorted view of some gerontological problems. Certain demographic aspects of old age are considered in detail with regard to the occurrence of, first, widowhood and, second, social isolation. (shrink)
