Redundant publication in biomedical sciences is the presentation of the same information or data set more than once. Forms
of redundant publication include “salami slicing”, in which similar text accompanies data presented in disaggregated fashion
in different publications and “duplicate or multiple publication” in which identical information is presented with a virtually
identical text. Estimates of prevalence of the phenomenon put it at 10 to 25% of published literature. Redundant publication
can be considered unethical, or fraudulent, when the author(s) attempt to conceal the existence of duplicate publication from
editors and readers. Redundant publication in the area of clinical trials is potentially dangerous as it tends to overestimate
the effects of interventions. The scientific community at large and governments should take urgent steps to safeguard the
public from the possible effects of fraudulent multiple publications. 相似文献

Six institutionalized conduct-problem children performed in a classroom under three reinforcement conditions: (1) noncontingent reinforcement: (2) reinforcement for being on task and (3) reinforcement for the accuracy and rate fo their academic behavior. Within each of these conditions, the teacher was either present throughout the class session or absent for a portion of the session. In the teacher's absence, on-task behavior was markedly reduced and disruption was markedly increased, regardless of the reinforcement condition in operation. In contrast, the teacher's absence had no effect on academic accuracy and had a major effect on academic rate only when reinforcement was delivered noncontingently. Furthermore, the extent to which the children became disruptive in the teacher's absence was reduced when reinforcement was contingent upon academic accuracy and rate, instead of being contingent upon being on task or delivered noncontingently. It is suggested that the reinforcement of academic behavior, rather than on-task behavior or classroom social behavior, not only will improve the latter behaviors as well, but possibly also make them less dependent upon the presence and continued surveillance of the teacher. 相似文献

Examination of efficacious,efficient, and socially valid error‐correction procedures to teach sight words and prepositions to children with autism spectrum disorder 下载免费PDF全文

Prior research shows that learners have idiosyncratic responses to error‐correction procedures during instruction. Thus, assessments that identify error‐correction strategies to include in instruction can aid practitioners in selecting individualized, efficacious, and efficient interventions. The current investigation conducted an assessment to compare 5 error‐correction procedures that have been evaluated in the extant literature and are common in instructional practice for children with autism spectrum disorder (ASD). Results showed that the assessment identified efficacious and efficient error‐correction procedures for all participants, and 1 procedure was efficient for 4 of the 5 participants. To examine the social validity of error‐correction procedures, participants selected among efficacious and efficient interventions in a concurrent‐chains assessment. We discuss the results in relation to prior research on error‐correction procedures and current instructional practices for learners with ASD. 相似文献

The satisfaction and frustration of the psychological needs for autonomy, relatedness and competence predict well-being and ill-being outcomes. However, research within educational and work contexts is stifled by the lack of an exhaustively validated measure. Following extensive preparatory and pilot work, the present three studies (total N = 762) aimed to develop such a measure and validate it against the Basic Need Satisfaction at Work Scale (Deci et al. in Personal Soc Psychol Bull 27(8):930–942, 2001) and an adapted version of the Balanced Measure of Psychological Needs (Sheldon and Hilpert in Motivation Emot 36(4):439–451, 2012). The Need Satisfaction and Frustration Scale demonstrated a better factor structure and internal reliability than its predecessors, and good criterion validity. This improvement was due to the exclusion of ambiguous items and items measuring antecedents of need satisfaction and frustration. The results also strengthen current evidence showing that need satisfaction and frustration are distinct but related constructs, and each better predicts well-being and psychological health problems, respectively. 相似文献

We examine how the authors who represent ‘New Atheism’ refer to science, and we compare these references to how science was viewed in earlier Continental forms of atheism, namely in Ernst Haeckel’s writings and his Monist movement. We analyse and compare these references in five key areas: the general reference to science, the use of science as an argument against religion, reference to a scientific mode of knowledge, scientific theories about religion and science as a means of giving meaning to life. While there are many similarities that clearly position New Atheism within the history of scientism, we find that the form of scientism the New Atheists employ owes at least as much to the current state of religious field as to their scientistic predecessors. 相似文献
