The presented paper substantiates the principle that values are an immanent component of science and any rational cognitive activity. This principle belongs to the European cultural tradition starting from the book of Genesis of the Old Testament, the values of certainty in the antique Greek philosophy and Francis Bacon's coincidence of knowledge and power. Values in science form complicated structures inconnection with different types of knowledge including “the knowledge that”, empirical evidence, various types of generalizations or rules, methods, directions, algorithms, “the knowledge how”, “the knowledge why” or other types of knowledge. Since the assignments of different types of values are the products of a decision-making, it is useful to distinguish many types of decision-making, especially semantic decision-making, information decision-making and decision-making with distinctly pragmatic dimensions. The values assignable to scientific activities and their results also include their social recognition, respect and prestige granted to knowledge and bearers of knowledge by society and social groups or communities. Knowledge generation and the rational and justified application of the achieved and acceptable impacts are also connected with decision-making procedures, values and criteria of social acceptance. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

This paper focuses on recent debates over the nature ofliberalism and its central feature of reason, both inside and outside ofeducational philosophy. Central ideas from Jonathan and Hirst contributeas do those from Rawls, Gadamer, Wittgenstein, Taylor, and Ackermantoward a less traditional contextualized and contingent view.  相似文献

Most preference assessments require individuals to choose among two or more stimuli. More recently, the duration of engagement with items has been used as an index of preference. In the current study, the predictive validity of a single stimulus engagement (SSE) preference assessment was evaluated with 4 individuals. Stimuli were presented singly for a brief period while engagement with that stimulus was recorded. Although SSE preference rankings closely matched paired stimulus preference assessment rankings for only 2 of the 4 participants, relative preference rankings based on duration of engagement predicted relative reinforcer effectiveness for all participants in a subsequent concurrent‐schedule reinforcer assessment. The SSE procedure took less time to administer than the paired stimulus procedure but produced less stable preference rankings across administrations. The SSE procedure may be appropriate for individuals who have difficulty selecting one stimulus from among two or more stimuli, and it may be well suited for evaluating activities that are difficult to present in a paired stimulus format.  相似文献

The issue of situational consistency is of great interest for early intervention with aggressive boys, but efforts to show behavior stability across settings have been unsuccessful to date, due principally to methodological problems. It is argued here that a more appropriate matching of response form, interaction partner, and situations should increase the situation consistency of observed behavior. The results support this proposition in that, more crosssetting behavior consistency was found in the pairing of situations where aggressive boys (age 6–7 years) were interacting with an adult female (mother/child versus baby-sitter/child) than in the pairing of situations where the boys were interacting with an adult male (mother/child versus father/child) or with the teacher in a nondyadic situation (classroom). The implications of using an extreme group are also discussed.This research program was funded by Le Conseil Québécois de la Recherche Sociale, the Quebec Government's FCAR research program, the Social Sciences and Humanities Research Council of Canada, the Canadian Ministry of Employment and Immigration, and the University of Montreal FDR program.  相似文献

This investigation was conducted in an effort to systematically extend the emerging data base having to do with choice-making opportunities and the behavior of students with disabilities. In particular, the current analyses examined the effects of choice-making on the problem behavior and task engagement of three high school students with intellectual disabilities as the students performed domestic and vocational activities. Multiple baseline and reversal designs demonstrated that the choice conditions reduced problem behaviors and increased task engagement for all participants. Data having to do with student affect and task productivity were less consistent. The findings on the relationship between choice making and problem behavior replicate and extend a growing literature on the desirable effects of choice-making for individuals with disabilities. The results are discussed in terms of recent developments in behavioral support, as well as the need for ongoing conceptual and applied research.  相似文献

This research focuses on the inappropriate, largely aggressive, behaviors of 344 K-2 children assigned to a playground prior to the beginning of the school day. Initially, a system for observing large numbers of children freely roaming over a large, open area was developed. This observational method was then used to determine the effectiveness of providing organized games for reducing potentially dangerous playground behaviors. Using a reversal (ABAB) design, it was found that the games, rope jumping, and foot racing, along with an infrequently used time-out procedure, significantly reduced the frequency of inappropriate incidents. It is suggested that when dealing with large groups, antecedent environmental manipulations may be more practical than providing consequences for the behaviors exhibited by identified individuals.  相似文献

Even though administrators must have effective staff-management procedures to ensure implementation of desired programs, many traditional staff-management procedures remain unevaluated. This study investigated the effectiveness of three such procedures. The administrator of an institution for the retarded (1) sent a memo instructing all staff to lead daily recreational activities, (2) sponsored a workshop teaching staff to lead such activities, and (3) assigned staff activity leaders and provided performance feedback to staff by publicly posting the daily average number of active residents on each ward. Neither the memo nor the workshops motivated staff to lead activities, but after staff were scheduled to lead such activities and given performance feedback, the average daily number of residents engaged in activities on four wards for 95 retarded persons increased from seven to 32. The administration of this facility has adopted similar procedures to maintain such activities on all wards.  相似文献

As a control for the effects of session duration and hunger on the relation between food magnitude and induced drinking, four food-deprived rats were exposed to a variable-time 50-s schedule of food delivery in which the size of each food delivery varied randomly within sessions. Food-related behavior and schedule-induced drinking per opportunity were examined as functions of meal size and postfood time. All rats showed an inverted-U-shaped relation between drinking per opportunity and meal size. This relation was caused by variation in the percentage of intervals that contained drinking and by variation in the number of drinking bouts per interval, rather than by bout duration or by the amount of drinking within those intervals that actually contained drinking. Head-in-feeder time increased linearly with meal size. Schedule-induced drinking was entrained by food delivery in 3 of 4 subjects; the entrainment was due to regulation of the starting time of each drinking bout rather than to regulation of bout duration.  相似文献
