[The] business man is generous to a fault, but one thing he does demand of all teachers and lecturers and journalists: if we're going to pay them our good money, they‘ve got to help us by selling efficiency and whooping it up for rational prosperity? And when it comes to these blab-mouth, fault-finding, pessimistic, cynical University teachers, let me tell you that during this golden coming year it's just as much our duty to bring influence to have these cusses fired as it is to sell all the real estate and gather in all the good shekels we can.

While feedback is widely considered central to student learning, students across the higher education sector commonly report dissatisfaction with the feedback they receive. In contrast, academics often feel they provide quality and informative feedback. This article explores and compares the perceptions of students and academics with regard to feedback practice. The paper presents the results of questionnaire surveys conducted with academics and students at the School of the Built Environment, Liverpool John Moores University. It highlights the perceptions of academics and students with regard to preferences for different types of feedback, timeliness of feedback, students’ engagement and interest in feedback, quality feedback and satisfaction with current practice. The findings indicate a significant discord between staff and students in relation to certain aspects of feedback practice, namely opinions on students’ engagement and interest in feedback, satisfaction with current practice and feedback preference. Similarities in viewpoints were also found in relation to quality feedback. 相似文献

Research Findings: Public policy has increasingly focused on expansion of preschool access for underserved students and systematic evaluation of preschool quality and students’ readiness for school. However, such evaluation is limited by a lack of thoroughly validated assessments for use with preschool populations. The present study examined the measurement and structural invariance of the Kindergarten Student Entrance Profile (KSEP) across kindergarten and prekindergarten groups to evaluate its potential use across developmental groups. Participants included 522 kindergarten and 548 prekindergarten students in central California. Invariance was tested by fitting a series of multiple-groups confirmatory factor analysis models with parameter constraints across groups. Results indicated that measurement and structural parameters of the KSEP were invariant across kindergarten and prekindergarten groups. Prekindergarten means on both Social–Emotional Readiness and Cognitive Readiness were significantly lower than kindergarten means. Practice or Policy: These results suggest that the KSEP may potentially be used with prekindergarten students to assess school readiness and inform intervention before kindergarten entry. 相似文献

Persons with Mental Illness (PMIs) require unique consideration and individualized attention in the criminal justice system. Research has demonstrated the prevalence with which police come into contact with these individuals, the unique considerations made by courtrooms serving PMIs, the overrepresentation of PMIs in correctional settings, and the problems PMIs experience when reentering the community from incarceration. Given the growth of attention to this area, and the increased reality of challenges that criminal justice professionals encounter when working with PMIs, this paper explores the prevalence of courses on mental illness in criminal justice undergraduate programs in the United States. The current review of over 640 curricula in the United States illustrates that courses devoted solely to the topic of mental illness in the criminal justice system are particularly rare. The importance of offering more courses in the interface between mental illness and criminal justice for future professionals in the field is discussed. 相似文献

This study examined whether specific relevance instructions affect transfer appropriate processing. Undergraduates (n = 52) were randomly assigned to one of three pre-reading question conditions that asked them what-questions, why-questions,
or to read for understanding (i.e., control condition). There were no differences in reading time across conditions for sentences
targeted by the pre-reading questions. There were three main findings with respect to cued recall. First, participants in
the experimental conditions did better on questions that had greater similarity to relevance instructions than questions that
had lesser similarity to relevance instructions. Second, participants in the experimental conditions did better on questions
that had greater similarity to relevance instructions than the participants in the other conditions on those same questions.
Third, participants in the control condition recalled equal amounts of information for both question. The results suggest
that specific relevance instructions promote transfer appropriate processing and affect the quality of memory for text. 相似文献

We provide causal evidence that regulation induced product shocks significantly impact aggregate demand and firm performance in pharmaceutical markets. Event study results suggest an average loss between $569 million and $882 million. Affected products lose, on average, $186 million over their remaining effective patent life. This leaves a loss of between $383 million and $696 million attributable to declines in future innovation. Our findings complement research that shows drugs receiving expedited review are more likely to suffer from regulation induced product shocks. Thus, it appears we may be trading off quicker access to drugs today for less innovation tomorrow. Results remain robust to variation across types of relabeling, market sizes, and levels of competition. 相似文献

This article explores the relationship between the perceived campus environment for gay, lesbian, bisexual, and transgender (GLBT) students at colleges and universities and how academic libraries have deployed GLBT-related resources on the Web. Recommendations are made for increasing GLBT-related materials and information in academic libraries. 相似文献

Real time search is an increasingly important area of information seeking on the Web. In this research, we analyze 1,005,296 user interactions with a real time search engine over a 190 day period. Using query log analysis, we investigate searching behavior, categorize search topics, and measure the economic value of this real time search stream. We examine aggregate usage of the search engine, including number of users, queries, and terms. We then classify queries into subject categories using the Google Directory topical hierarchy. We next estimate the economic value of the real time search traffic using the Google AdWords keyword advertising platform. Results shows that 30% of the queries were unique (used only once in the entire dataset), which is low compared to traditional Web searching. Also, 60% of the search traffic comes from the search engine’s application program interface, indicating that real time search is heavily leveraged by other applications. There are many repeated queries over time via these application program interfaces, perhaps indicating both long term interest in a topic and the polling nature of real time queries. Concerning search topics, the most used terms dealt with technology, entertainment, and politics, reflecting both the temporal nature of the queries and, perhaps, an early adopter user-based. However, 36% of the queries indicate some geographical affinity, pointing to a location-based aspect to real time search. In terms of economic value, we calculate this real time search stream to be worth approximately US $33,000,000 (US $33 M) on the online advertising market at the time of the study. We discuss the implications for search engines and content providers as real time content increasingly enters the main stream as an information source. 相似文献
