This article begins with an analysis of reliability and usability in the mathematical literature. Mathematical practice is
seen to be adapted to very high standards in these respects, and quite sensitive to even modest declines in quality. Unfortunately
most scenarios for the transition to electronic publication suggest serious loss of quality. This is a problem special to
mathematics: other sciences are adapted to lower standards, and should be much less sensitive to changes. Some ways to prevent
this decline are suggested.

Public libraries across the country design and deliver programs for military veterans and their families, often collaborating with other organizations and agencies. The examples were assembled from both general and specialized interviews with librarians, and literature and Internet searches, with summaries of programs assembled and written by multiple researchers. The specific limitations on the listing in this article are clearly outlined in the first section. Overall, however, the article provides a good introductory overview of what’s going on in veteran’s programs and services in America’s public libraries in over seventy libraries in forty states. We hope this list of what public libraries have organized or are doing will supply other public librarians with ideas on how to provide new services or enhance their existing ones. 相似文献

Aims
Speed reading is advertised as a way to increase reading speed without any loss in comprehension. However, research on speed reading has indicated that comprehension suffers as reading speed increases. We were specifically interested in how processes of inference generation were affected by speed reading.Methods
We examined how reading speed influenced inference generation in typical readers, trained speed readers and participants trained to skim read passages. Passages either strongly or weakly promoted a bridging or predictive inference. After reading, participants performed a lexical decision task on either a nonword, neutral or inference‐related word.Results
Typical readers responded to strong and weak inference words faster than neutral words. There were no statistical differences in reaction time between inference‐related and neutral words for speed and skim readers.Conclusions
These findings provide no substantive evidence that the appropriate inferences are generated when reading at rapid speeds. Thus, speed reading may be detrimental to normal integrative comprehension processes. 相似文献5.

Pigeons' keypecking was reinforced by food on baseline schedules of multiple variable interval (VI) x VI x and on contrast schedules of multiple VI x VI y. Deprivation of food was varied by maintaining subjects at 75%, 85%, and 95% (+/- 2%) of their free-feeding weights. Positive and negative behavioral contrast were observed. The size of the contrast was not systematically altered by changes in deprivation. Positive and negative contrast were both larger later in the session than they were earlier. Within-session decreases in responding were steeper for the baseline than for the contrast schedules for positive contrast. Within-session decreases were steeper for the contrast than for the baseline schedules for negative contrast. These results were predicted by the idea that different amounts of habituation to the reinforcer during the baseline and contrast schedules contribute to behavioral contrast. The results show that contrast occurs under conditions that reduce the effect of the following component. The results support the assumption that positive and negative contrast are produced by symmetrical theoretical variables. 相似文献

Education in different communication media takes place with functional differences that have consequences for the course of instructional interaction. In this paper, we examine instructional interaction among people using a computer-based electronic message system, contrasting it with conventional face-to-face discussion in a college level class. Interaction via the non-real time message system contained multiple “threads of discourse,” a higher proportion of student turns to teacher turns, and other deviations from the “initiation-response-evaluation” sequences usually found in face-to-face classroom interactions. Based on the results of our contrast, we describe ways to organize instruction using electronic message systems to take advantage of new properties and to avoid shortcomings of these new instructional media. 相似文献

Conclusion This leisure counseling model provides a general framework for the counseling process rather than a strict guideline. While some clients may progress orderly through the stages, other clients may move back and forth amongst different stages. The specific counseling needs of each client should guide the client's progress through the model accordingly. In short, within the model's framework the counseling process has a great deal of flexibility.The purpose of this article has been to emphasize the importance of leisure counseling for addicted persons and to present a corresponding model that can supplement existing programs and support groups. Thus, the model is designed in such a way that it can be implemented in either individual or group settings. Whatever the particular application of this leisure counseling model, it adds an important extra dimension to existing addiction treatment approaches.The importance of leisure counseling for addicted persons in recovery cannot be overemphasized. Because the addiction was the center of their lives, recovering addicts must forge a new lifestyle without their drug of choice: their best friend and greatest source of security and reassurance. Recognizing their struggle, the addiction leisure counseling model should help counselors facilitate this transition by enabling addicted clients to begin using leisure to satisfy many of their unmet needs. 相似文献

The academic and social integration of college students has been the focus of much recent research. The Tinto model of college student withdrawal focused on the constructs as explanation for commitment to goals and persistence. Research results suggested that perhaps reciprocal relationships existed between academic and social integration. Significant influences from academic integration to social integration and vice-versa indicated differing reciprocal effects for males and females. 相似文献

Pigeons categorized binomial samples produced by two complementary random processes. Samples were 1, 2, 4, or 8 successively presented outcomes (vertical or horizontal lines) of, in effect, tossing one of two equally likely coins. One coin (A) was biased in favor of vertical, and the other coin (B) was similarly biased in favor of horizontal. Choosing red or green stimuli presented after each sample was reinforced with food if coin A or coin B had been tossed, respectively. In that sense, choosing red or green was logically analogous to inferring that the statistical evidence reflected tossing of coin A or coin B, respectively. The statistical diagnosticity of a sample, the relative likelihood of its having been produced by a particular coin, equaled, except for sampling fluctuation, the relative frequency of reinforcement of a particular color given that sample, and was experimentally varied by the bias on the coins and by sample size. All the variables that affect optimal, formal inference about binomial samples also affected intuitive inference. But inferences were very suboptimal: “undermatching” was obtained in part due to control of categorization by the sequential structure of binomial samples. These results reveal limitations of optimality theories for animal decision making in the face of uncertainty when observations in samples are presented successively. On the other hand, they are generally compatible with molecular analyses of instrumental learning which assign an important role to the local temporal organization of events preceding reinforcement. Most generally, they show that maladaptive control over intuitive statistical inference by a variable upon which optimal performance does not depend is neither a uniquely human phenomenon nor dependent upon linguistic strategies. 相似文献
