In Fall 2008, the interlibrary loan office at the College of Staten Island began to use ILLiad and SFX OpenURL to fulfill borrowing requests. Four years later a review showed that patrons used SFX to submit borrowing requests less than half the time. The majority of patrons’ borrowing request submissions were still being entered manually. We decided to review patron submission methods and see what impact this was having on transactions. We also explored possible patterns in order to encourage SFX usage and improve patron services. Reasons for this behavior are suggested and future solutions are explored. 相似文献

Because body mass change (ΔMb) does not represent all water losses and gains, the present field investigation determined if (a) ΔMb equalled the net effective body water change during ultra-endurance exercise and (b) ground speed and exercise duration influenced these variables. Thirty-two male cyclists (age range, 35–52 years) completed a 164-km event in a hot environment, were retrospectively triplet matched and placed into one of three groups based on exercise duration (4.8, 6.3, 9.6 h). Net effective body water loss was computed from measurements (body mass, total fluid intake and urine excreted) and calculations (water evolved and mass loss due to substrate oxidation, solid food mass and sweat loss), including (ΔEBWgly) and excluding (ΔEBW) water bound to glycogen. With all cyclists combined, the mean ΔMb (i.e. loss) was greater than that of ΔEBWgly by 1200 ± 200 g (P = 1.4 × 10–18), was similar to ΔEBW (difference, 0 ± 200 g; P = .21) and was strongly correlated with both (R2 = .98). Analysis of equivalence indicated that ΔMb was not equivalent to ΔEBWgly, but was equivalent to ΔEBW. Due to measurement complexity, we concluded that (a) athletes will not calculate the effective body water calculations routinely and (b) body mass change remains a useful field-expedient estimate of net effective body water change. 相似文献

The author applies a quantitative analysis to data collected on a multi‐shift organization. The results are compared with a review of literature and the principles of organizational communication in single‐shift organizations. 相似文献

Decades of research have demonstrated that women experience higher rates of math anxiety – that is, negative affect when performing tasks involving numerical and mathematical skill – than men. Researchers have largely attributed this sex difference in math anxiety to factors such as social stereotypes and propensity to report anxiety. Here we provide the first evidence that the sex difference in math anxiety may be due in part to sex differences in spatial processing ability. In Study 1, undergraduate students completed questionnaires assessing their level of math anxiety and their aptitude and preference for processing spatial configurations and schematic images. The results support the hypothesis that the relation between sex and math anxiety is mediated by spatial processing ability. In Study 2, we replicate these results with a more diverse sample of adults. Implications for the prevention and remediation of math anxiety and math anxiety-related achievement deficits are discussed. 相似文献

Harris and Livesey. Learning & Behavior, 38, 1-26, (2010) described an elemental model of associative learning that implements a simple learning rule that produces results equivalent to those proposed by Rescorla and Wagner (1972), and additionally modifies in "real time" the strength of the associative connections between elements. The novel feature of this model is that stimulus elements interact by suppressively normalizing one another's activation. Because of the normalization process, element activity is a nonlinear function of sensory input strength, and the shape of the function changes depending on the number and saliences of all stimuli that are present. The model can solve a range of complex discriminations and account for related empirical findings that have been taken as evidence for configural learning processes. Here we evaluate the model's performance against the host of conditioning phenomena that are outlined in the companion article, and we present a freely available computer program for use by other researchers to simulate the model's behavior in a variety of conditioning paradigms. 相似文献

Three experiments tested whether events taking place before a rat has access to a target taste, sucrose, can proactively interfere with the acquisition of a sucrose aversion when sucrose is followed by a lithium chloride injection. Using a serial overshadowing procedure with various delays before lithium injection, proactive interference by a taste (Experiments 1 and 3) and by a novel context (Experiment 2) was found following two conditioning sessions, but not after a single conditioning session. Conversely, overshadowing by a taste given after the target was detectable after a single conditioning trial (Experiment 3) and, thus, indicated that retroactive interference involves a process different from that producing proactive interference. A simulation confirmed that the results are consistent with a modified Rescorla and Wagner (1972) interpretation of Revusky??s (1971) concurrent interference theory of delay learning. 相似文献

This article illustrates details of the planning, building, and improvement phases of a cost‐efficient, full‐dissection gross anatomy laboratory on a campus of an historically design‐centric university. Special considerations were given throughout the project to the nature of hosting cadavers in a building shared amongst all undergraduate majors. The article addresses these needs along with discussion of relevant furnishings and infrastructure that went into the creation of a fully outfitted gross anatomy laboratory (ten cadavers) completed within a significantly constrained timeline and $210,000 budget.

After special training, 67 teachers of the third through sixth grades, with a total of 1853 pupils, each conducted an experience-based social studies program in his or her own class during the semester following the training. The program, the Mini-Society, requires considerable pupil autonomy. Half of the classes were taught by teachers with the highest success orientation toward teaching. These students showed significantly larger residual gains on perceived personal control of their own academic success and failure and on favorable attitude toward learning than did students in classes taught by the other half of the teachers, who were oriented more toward avoidance of failure in their teaching. 相似文献

New World primates face problems of communication distinct from those of their Old World counterparts. We suspected that the odor of urine might serve the function of communicating information among animals or troops. Two studies were conducted withSaimiri sciureus; one examined, in a laboratory enclosure, the influence of breeding season, social condition, area, and whether the urine was from known animals or from strangers, and the second measured, in a seminatural rain forest, responses to our spreadingSaimiri urine on selected sites. Enclosure and field produce the same general patterns of frequencies of behavior for urination, the urine wash and kick wash, and rubbing. The chief difference in behavior between the environments is found in the frequency of sneezing. Season (breeding or nonbreeding) is the most effective variable producing this general pattern: During the breeding season, males urine-wash throughout the enclosure or troop range, whereas during the nonbreeding season, this behavior is restricted in location, at least in the enclosure. At this time, females increase their frequencies of sniffing and rubbing. Many of these behaviors are observed only in special locations of the enclosure. The results show thatSaimiri respond differently to the urine of known and foreign animals, depending upon the season and whether they are with members of their own sex or both sexes. It is suggested that primates not equipped with specialized organs for scent marking may use urine opportunistically to communicate. 相似文献
