This article reports on a multi-dimensional model to collection development and licensing applied in our library following a major separation from a joint-licensing venture with another institution. Our model includes the use of several core metrics, including usage and the context in which usage is measured. The model includes three metrics; Research Intensity (RI), Educational Intensity (EI) and Clinical Intensity (CI). These metrics take into account the differences between research and non-research departments, and their disciplinary foci. This model can be used in its entirety or can be customized by selecting the metrics that fits the needs of the library.  相似文献

The categorization performance of monkeys on a unidimensional perceptual categorization task was examined with reference to decision bound and exemplar theories of categorization. Three rhesus monkeys were presented with stimuli varying along a single dimension, the displacement of a target light from a fixation point. Left or right saccade responses were probabilistically reinforced according to one of three functions, two of which were nonmonotonic at one end of the stimulus space. The monkeys all showed a monotonic increase in response probability as a function of target light displacement in this region, consistent with decision bound theory. Fits of a single-boundary model (GRT; Ashby & Gott, 1988) and two exemplar models—one using a probabilistic response function (GCM; Nosofsky, 1986), the other using a deterministic response function (DEM; Ashby & Maddox, 1993)—revealed overall support for the decision bound model. The results suggest that monkeys used a perceptual decision boundary to perform the task.  相似文献

In this case study, a group of nine 4th grade children were introduced to the Logo programming language during three 90-minute sessions over a four-week period. They attended a private university-based laboratory school serving students with various learning disabilities. This project demonstrated that a classic version of Logo captured the students’ interest. It was a viable source of interactive challenge and problem-solving experience that provided students with a great deal of pride, intrinsic reward, enjoyment, and sense of ownership of learning. The process of overcoming obstacles while programming with Logo may be especially beneficial for students with mild disabilities.  相似文献

Economic hardship can affect children's development through child–caregiver interactions, which may mediate cascading effects of other family stress processes. This study examined, simultaneously, the relations of financial strain, caregiver general stress, and child–caregiver conflict—each measured at two time points—with child self-regulatory outcomes in a high-poverty sample (age 5–7 years; n = 343). Increase in child–caregiver conflict mediated negative relations between other processes and development of executive function. In contrast, only increase in financial strain had direct, negative association with development of delay of gratification and did not significantly mediate relations between any other process and children's outcomes. Results have implications for understanding effects of family stress on self-regulatory outcomes and for interventions with low-income families.  相似文献

In this article we explore examples of public pedagogical actions and interventions, reading them through a social justice education framework lens. In our discussion we start with definitions of social justice, public pedagogy and case study methodologies. Then, we look at a variety of international examples to highlight the pervasiveness of public pedagogical opportunities in visual culture that include a festival, an individual, a citywide symposium, an online community, a cultural group and a museum exhibition. They are divided into three categories based on social justice principles suggested by Ayers et al. and later interpreted by Dewhurst: (1) Public pedagogy and social justice is rooted in people's experiences: Fiesta del Señor de Choquekillka: Ollantaytambo, Peru and Janet Weight Reed – an artist's public pedagogy utilising social media; (2) Public pedagogy and social justice is a process of reflection and action together: Ideas City Festival and the Vlogbrothers; (3) Public pedagogy and social justice seeks to dismantle systems of inequality to create a more humane society: CULTURUNNERS and sh[OUT]: Lesbian, Gay, Bisexual, Transgender and Intersex art and culture. It is our hope that in looking more closely at these international examples of public pedagogy and social justice education that the power of such alternative sites of learning is apparent and encourages further interventions and investigations in such spaces of inquiry.  相似文献

Historians of science have long believed that Abraham Trembley's celebrity and impact were attributable chiefly to the incredible regenerative phenomena demonstrated by the polyp, which he discovered in 1744, and to the new experimental method he devised to investigate them. This essay shows that experimental method alone cannot account for Trembley's success and influence; nor are the marvels of the polyp sufficient to explain its scientific and cultural impact. Experimental method was but one element in a new conception of the laboratory that called for both experimental and para-experimental skills whose public availability depended on a new style of communication. The strategy of generosity that led Trembley to dispatch polyps everywhere enabled experimental naturalist laboratories to spread throughout Europe, and the free circulation of living objects for scientific research led practitioners to establish an experimental field distinct from mechanical physics. Scholars reacted to the marvels of the polyp by strengthening the boundaries between the public and academic spheres and, in consequence, opened a space for new standards in both scientific work and the production of celebrity.  相似文献

Background:Project ECHO (Extension for Community Healthcare Outcomes) is a telehealth initiative that aims to reduce disparities in delivery of health care by leveraging technology and local expertise to provide guidance on specialized subjects to health care providers across the world. In 2018, a new ECHO hub convened in Indianapolis with a focus on health care for individuals in the lesbian, gay, bisexual, trans, and queer (LGBTQ+) populations. This ECHO iteration was one of the first of its kind and would soon be followed by a new human immunodeficiency virus (HIV) ECHO as well.Case Presentation:In a novel approach, information professionals participated in the early planning stages of the formation of these ECHO teams, which enabled the provision of real-time medical evidence and resources at the point-of-need once the teams were launched. This case study demonstrates proof of concept for including health sciences librarians and/or information professionals in the ECHO as hub team members. In this case study, the authors describe and quantify the value added to the HIV and LGBTQ+ ECHO sessions by the medical librarians, as well as provide a template for how other telehealth initiatives can collaborate with their local health information professionals.Conclusions:Librarian involvement in Project ECHO over the past three years has been enthusiastically received. The librarians have contributed hundreds of resources to ECHO participants, helped build and curate resource repositories, and expanded the embedded librarian program to an additional two ECHO iterations. ECHO hub team members report high rates of satisfaction with the performance of embedded librarians and appreciate the provision of point-of-need evidence to ECHO participants.  相似文献

Previous research has demonstrated significant decreases in pain perception in healthy individuals following both aerobic and upper body resistance exercise, but research on circuit training has been limited. The purpose of the study was to determine the effects of a strenuous bout of dynamic circuit resistance exercise on pain threshold and pain tolerance in conjunction with changes in blood lactate levels, heart rate (HR), and perceived exertion. A sample of 24 college-age students participated in 2 sessions: (1) a maximal strength testing session and (2) a circuit training bout of exercise that consisted of 3 sets of 12 repetitions with a 1:1 work to rest ratio at 60% one-repetition maximum (1-RM) predicted from a three-repetition maximum (3-RM) for 9 exercises. Participants exhibited increases in pain tolerance, blood lactate levels, HR and perceived exertion following resistance exercise. Preference for exercise intensity was positively correlated with lactate post exercise and tolerance for exercise intensity was positively correlated with pain tolerance and lactate post exercise. In conclusion, this is the first study to demonstrate increases in pain tolerance following a dynamic circuit resistance exercise protocol and disposition for exercise intensity may influence lactate and pain responses to circuit resistance exercise.  相似文献
