A transaction log analysis of the Nanyang Technological University (NTU) OPAC was conducted to identify query and search failure patterns with the goal of identifying areas of improvement for the system. One semester’s worth of OPAC transaction logs were obtained and from these, 641,991 queries were extracted and used for this work. Issues investigated included query length, frequency and type of search options and Boolean operators used as well as their relationships with search failure. Among other findings, results indicate that a majority of the queries were simple, with short query lengths and a low usage of Boolean operators. Failure analysis revealed that on average, users had an almost equal chance of obtaining no records or at least one record to a submitted query. We propose enhancements and suggest future areas of work to improve the users’ search experience with the NTU OPAC. 相似文献

Relative to print reading, braille-reading finger movements are held to be of more constant speed, with continuous and exhaustive contact with all words. However, the continuity of movements is intermittent in two distinct ways: (a) readers reverse direction and reread material already encountered and (b) the continual fluctuations of velocity between phases of acceleration and deceleration. We analyze recordings of experienced readers’ encounters with ambiguous sentences predicted to encourage more reversals, and we undertake comparative kinematic analyses of the finger movements during such reading. The data suggest that when reversals are initiated and where they are targeted reflect language-processing demands. However, their kinematic properties are not qualitatively different from those of forward reading. We conclude that how readers of braille move the reading finger—both forward and in reverse—is primarily influenced by the control properties of low-velocity movements and only secondarily by language properties. 相似文献

Prior research has shown a correlation between market orientation and business performance as measured through new product success. Market orientation has traditionally been measured through the MKTOR and MARKOR scales developed by Narver and Slater and Kohli et al., respectively. We examine whether there might be a different, complementary way to study market orientation. Kohli and Jaworski discuss the role of networks in achieving higher levels of market orientation, but network analysis has not previously been used to study market orientation. Following Kohli and Jaworski we find that network analysis can show how information is gathered and disseminated within a group; and following Narver and Slater we find that network analysis can be used to examine customer orientation and coordination. We discover a possible association between the organization’s structure and its level of coordination, and that certain roles within the group facilitate increased customer orientation within the team. Our research suggests that network analysis, particularly when managers participate in the interpretation of results, can be an effective means of identifying and correcting obstacles to a team’s market orientation. We believe our research contributes to theory by showing an alternative, complementary way to study market orientation and suggests factors that contribute to a group’s level of market orientation. We believe that this research contributes to practice by providing managers with a practical measure to improve their organization’s market orientation, thus increasing the likelihood of new product success. 相似文献

This paper seeks to explain why an acquiring organization was unable to leverage the expertise of the acquired organization even though both organizations were highly successful in their own right prior to the acquisition. It offers a knowledge-based perspective by teasing out the essential knowledge attributes pertinent to acquisitions. The research was carried out using an interpretative case study methodology at a Singapore-based multinational organization in the semi-conductor industry. The main data collection method used was face-to-face interviews with some 28 staff from October 2006 to December 2006, almost 2 years after the acquisition exercise. The findings suggest that the lackluster outcome could be traced to three knowledge attributes, namely, accessibility, applicability and cumulativeness. In conclusion, a number of practical and research implications are highlighted. 相似文献

It is currently considered imperative to introduce reading instruction as early as possible. This proposition was tested by assigning groups of kindergarteners (N = 256) to two conditions differing in their emphasis on prevention. In the first, teacher‐implemented research‐based interventions were implemented during kindergarten and first grade. In the second, only the first‐grade intervention was implemented. Analyses were conducted separately for students not at risk, at low risk, and at high risk of reading problems. In the short term, the kindergarten intervention was highly effective for both low‐risk and high‐risk students, but it is only for the latter group that early gains translated into better reading skills at the end of first grade. Not‐at‐risk students did not benefit from the early introduction of reading instruction. 相似文献

Two pivotal and interconnected claims are addressed in this article. First, strategy precedes program effectiveness. Second, graduation rates and rankings are insufficient in any account of academic progress for African American students. In this article, graduation is regarded as the floor and not the ceiling, as it were. The ideal situation in the promotion of strategy is the alignment of high graduation rates or rankings with high graduation cumulative grade point averages. This strategic alignment is precisely what needs to be formulated in the first instance before making judgments about program development and/or operational effectiveness. The work of the Office of African American Affairs of the University of Virginia provides the context for observing trends in academic performance that illustrate the optimal alignment between high graduation rankings and correspondingly high grade point averages. 相似文献

In spite of the widening racial achievement gap among U.S. college students (U.S. Census Bureau, 2011), some universities are achieving success in supporting the graduation and postcollege goals of Black undergraduates (Apprey, Bassett, Preston-Grimes, Lewis, & Wood 2014/this issue; Baker, 2006; Hrabowski, 2003; Hrabowski & Maton, 2009). Although research has documented efforts to improve students’ college academic success in mathematics, science, and engineering (Maton & Hrabowski, 2004), little research has examined the role of undergraduate support programs across the academic disciplines to bridge success for students from high school graduation through graduate school matriculation. This is a key link in the pipeline to career and lifelong achievement for Black students. The following case study describes an inclusive cluster-mentoring model for Black undergraduates at a Research I university that includes four elements—(a) student peer-advising, (b) faculty–student academic mentoring and advising, (c) culturally sensitive initiatives, and (d) organized parental support—to create high impact with measurable results. This university-based model can serve as a guide to improve and expand services that support the academic and leadership success of Black undergraduate students in other higher education settings. 相似文献

Adolescents who drop out of high school experience enduring negative consequences across many domains. Yet, the circumstances triggering their departure are poorly understood. This study examined the precipitating role of recent psychosocial stressors by comparing three groups of Canadian high school students (52% boys; Mage = 16.3 years; N = 545): recent dropouts, matched at‐risk students who remain in school, and average students. Results indicate that in comparison with the two other groups, dropouts were over three times more likely to have experienced recent acute stressors rated as severe by independent coders. These stressors occurred across a variety of domains. Considering the circumstances in which youth decide to drop out has implications for future research and for policy and practice. 相似文献
