One of the most active areas of research in semi-supervised learning has been to study methods for constructing good ensembles of classifiers. Ensemble systems are techniques that create multiple models and then combine them to produce improved results. These systems usually produce more accurate solutions than a single model would. Specially, multi-view ensemble systems improve the accuracy of text classification because they optimize the functions to exploit different views of the same input data. However, despite being more promising than the (...) single-view approaches, document datasets often have no natural multiple views available. This study proposes an algorithm to generate a synthetic view from a standard text dataset. The model generates a new view from the standard bag-of-words approach using an algorithm based on hidden Markov models. To show the effectiveness of the proposed HMM-based synthetic view generation method, it has been integrated in a co-training ensemble system and tested with four text corpora: Reuters, 20 Newsgroup, TREC Genomics and OHSUMED. The results obtained are promising, showing a significant increase in the efficiency of the ensemble system compared to a single-view approach. (shrink)

The word ‘existentialism’ has become something of a catchword in religious circles today, and one suspects that it is sometimes a substitute rather than a medium for thought. Most theological teachers must from time to time have received from a pupil an essay in which the words ‘existential’, ‘existentially’ and ‘existentialism’ appear to have been sprinkled from a pepper-pot over an exposition whose meaning would remain unchanged if these words were excised altogether. Nevertheless, usum non tollit abusus, and the following (...) rather unsystematic remarks may perhaps be of some help in elucidating and evaluating a mode of thought and expression which has attracted the interest of some of the more profound, as well as of some of the more superficial, theological and philosophical writers of the present day.

The current article aims to provide an up-to-date synopsis of available techniques to study affect dynamics using intensive longitudinal data. We do so by introducing the following eight dichotomies that help elucidate what kind of data one has, what process aspects are of interest, and what research questions are being considered: single- versus multiple-person data; univariate versus multivariate models; stationary versus nonstationary models; linear versus nonlinear models; discrete time versus continuous time models; discrete versus continuous variables; time versus frequency domain; (...) and modeling the process versus computing descriptives. In addition, we discuss what we believe to be the most urging future challenges regarding the modeling of affect dynamics. (shrink)

Research Ethics Committees (RECs) are frequently a focus of complaints from researchers, but evidence about the operation and decisions of RECs tends to be anecdotal. We conducted a systematic study to identify and compare the ethical issues raised in 54 letters to researchers about the same 18 applications submitted to three RECs over one year. The most common type of ethical trouble identified in REC letters related to informed consent, followed by scientific design and conduct, care and protection of research (...) participants, confidentiality, recruitment and documentation. Community considerations were least frequently raised. There was evidence of variability in the ethical troubles identified and the remedies recommended. This analysis suggests that some principles may be more institutionalized than others, and offers some evidence of inconsistency between RECs. Inconsistency is often treated as evidence of incompetence and caprice, but a more sophisticated understanding of the role of RECs and their functioning is required. (shrink)

Whether we like it or not, whether we realize it or not, the methods of science impinge upon and affect our daily lives. In the four centuries during which they have been properly understood and used, these scientific methods not only have enlarged man's stock of knowledge many thousandfold but also have helped bring about changes in outlook and, indeed, in man's physical environment, far outstripping the changes that took place throughout all the rest of recorded human history. Yet, one (...) of the paradoxes of our time is that, while we live in an increasingly scientific and technological society, the ordinary citizen's knowledge of and interest in scientific and technical matters seem, in fact, to be declining. This lack of interest sometimes amounts almost to hostility. As a result, leadership, possibly even direct control, of world affairs may be well pass to those nations which are prepared to cultivate their science and technology, while, on a national scale, if the trend continues, only an esoteric "scientific priesthood" will be able to make many of the most important decisions. The sole answer - the only defense - is knowledge. To arouse the interest of laymen and students in scientific and technical matters is E. L. Dellow's purpose in writing this book. To achieve this aim, he exploits a trait inherent in most of us - a delight in watching other people work. Rather than setting out to dazzle us by reciting the achievements of science and technology, however, he shows how scientific knowledge, which makes the spectacular achievements possible, is gained, and he gives us some insight into the way in which scientists and technicians think and work. In the course of doing so, he also gives the reader who may not previously have taken an interest in these subjects a painless introduction to basic mathematical principles and other techniques of scientific research, discovery, and invention. -- from dust jacket.

Medical educators invoke professionalism as a core competency in curricula. This paper criticizes classic definitions. It also identifies some negative traits of medicine as a profession. The call to professionalism is naive nostalgia. Straightforward didactics in professionalism cannot do the desired work in medical education. The most we can say is that students should adopt the good aspects of professionalism and the profession should stop being some of what it has been. This is a platitude. If the notion is to (...) be more than shallow, each student and practitioner will have to engage in much dialogue, reflection and refinement over many years. (shrink)

Abstract. We argue that all human beings have a special type of dignity which is the basis for (1) the obligation all of us have not to kill them, (2) the obligation to take their well-being into account when we act, and (3) even the obligation to treat them as we would have them treat us, and indeed, that all human beings are equal in fundamental dignity. We give reasons to oppose the position that only some human beings, because of (...) their possession of certain characteristics in addition to their humanity (for example, an immediately exercisable capacity for self-consciousness, or for rational deliberation), have full moral worth. What distinguishes human beings from other animals, what makes human beings persons rather than things, is their rational nature, and human beings are rational creatures by virtue of possessing natural capacities for conceptual thought, deliberation, and free choice, that is, the natural capacity to shape their own lives.
