Abstract This case study focuses on user research that was conducted to enhance our users’ ebook discovery experience. We took an outward-facing approach by seeking the users’ perspectives. We wanted to know: How do users find ebooks? How do they perceive multiple records for the same title? Would users find additional metadata useful, such as download availability, file format, and chapter titles? We coordinated guerilla usability testing in our library lobby, inspired by low-overhead, high-impact user experience work at other academic libraries. The resulting data gave us a much-needed new perspective of ebook usage that supplements what we already know from our day-to-day work. 相似文献

Simultaneous model-based clustering and visualization in the Fisher discriminative subspace 总被引:1,自引:0,他引:1
Clustering in high-dimensional spaces is nowadays a recurrent problem in many scientific domains but remains a difficult task
from both the clustering accuracy and the result understanding points of view. This paper presents a discriminative latent
mixture (DLM) model which fits the data in a latent orthonormal discriminative subspace with an intrinsic dimension lower
than the dimension of the original space. By constraining model parameters within and between groups, a family of 12 parsimonious
DLM models is exhibited which allows to fit onto various situations. An estimation algorithm, called the Fisher-EM algorithm,
is also proposed for estimating both the mixture parameters and the discriminative subspace. Experiments on simulated and
real datasets highlight the good performance of the proposed approach as compared to existing clustering methods while providing
a useful representation of the clustered data. The method is as well applied to the clustering of mass spectrometry data. 相似文献

ABSTRACTThe authors discuss transference enactments that occur during cross-cultural supervision. Previous research has shown that few mental health professionals willingly talk about race during supervision and that White supervisees experience significant difficulty when directly engaged in discussions about race. They introduce a new phenomenon, “stereotypical” transference enactments, as a means for understanding the countertransference Black female clinical supervisors experience during clinical supervision of White supervisees. The findings indicated that effective cross-cultural supervision should address the intersectionality of race and gender to enhance the development of multicultural clinical skills. The clinical and educational challenges are discussed by using two case vignettes. 相似文献

In the behavioral health environment, nurses often use continuous staff monitoring and, at times, physical restraints, to manage the severity of patients' self-injury. Both options put staff in control, are the most restrictive in nature, and can be financially draining on the hospital's budget. This can result in negative reactions by both patients and staff. It is important to develop a program that will empower patients to control their behavior and allow staff to be aware of their perceptions and attitudes toward patients who self-injure. This article describes the leadership initiative that drove the development, training, and implementation of a self-injury prevention project and the lessons learned by staff. 相似文献

The emergence of positive psychology has generated increased interest about the correlates of positive psychological functioning. Researchers have identified and studied various positive psychological constructs (e.g., hope, optimism, self-efficacy, gratitude, and life satisfaction) and found them to covary and to be positively associated with optimal human functioning and negatively associated with mental illness. This study of 528 college students examined the co-occurrence of selected positive psychological traits and explored their relations with a proposed second-order latent construct called covitality and with psychological well-being. Structural equation modeling examined each first-order positive psychology construct related to the second-order concept of covitality. Findings supported the second-order latent factor model of covitality, which was also significantly related to indicators of psychological well-being. Implications for theory development related to understanding positive human resources and applications within the context of college student populations are discussed. 相似文献

Parsons's tripartite model suggests that gaining information about the world of work is a critical factor in vocational decision making. This article compares and contrasts data from around 1909, when F. Parsons's Choosing a Vocation was published, with contemporary data on the workplace and the American worker. Data on other contextual factors, such as demographic trends, are also presented. There are surprising similarities between Parsons's time and the present, and also obvious differences. The author suggests that having information about occupations is still an essential component of career counseling, and ideas are presented for updating knowledge about the increasingly complex world of work. 相似文献

Mexican American youth often engage in relatively high levels of prosocial behaviors. We theorize that this may be due to a cultural value system that encourages familism values, which, in turn, may foster the development of sociocognitive processes that promote prosocial behaviors. Two hundred and five Mexican American early adolescent youth (Mage = 10.9 years, SD = 0.84; 51% girls) reported their familism values, perspective taking, prosocial moral reasoning, and six types of prosocial behaviors. The results indicated that perspective taking partially mediated the relation between familism values and the specific prosocial tendencies theoretically linked to the Mexican American culture. The study demonstrated the utility of integrating cultural and traditional developmental mechanisms in attempting to explain prosocial behaviors. 相似文献

Socio-semantic networks involve agents creating and processing information: communities of scientists, software developers, wiki contributors and webloggers are, among others, examples of such knowledge networks. We aim at demonstrating that the dynamics of these communities can be adequately described as the coevolution of a social and a socio-semantic network. More precisely, we will first introduce a theoretical framework based on a social network and a socio-semantic network, i.e. an epistemic network featuring agents, concepts and links between agents and between agents and concepts. Adopting a relevant empirical protocol, we will then describe the joint dynamics of social and socio-semantic structures, at both macroscopic and microscopic scales, emphasizing the remarkable stability of these macroscopic properties in spite of a vivid local, agent-based network dynamics. 相似文献
