OBJECTIVES: Medical Library Association (MLA) members were surveyed to gather background about the current state of expert searching in institutions. The survey results were intended to guide the recommendations of the Task Force on Expert Searching for promoting the importance of expert searching and implementing those recommendations. METHODS: MLA members were surveyed, and data obtained from the survey were compiled and analyzed to answer three general questions: what is the perceived value of searching skills to the institution, how do health sciences librarians maintain and improve their searching skills, and how are searching services promoted and/or mandated in the institution. RESULTS: There were 256 responses to the survey. Over 95% of the respondents saw their expert-searching skills were of value to their institutions, primarily through performing mediated searches and search consultations. Over 83% of the respondents believed that their searching skills had improved over the past 10 years. Most indicated that continued training was very important in maintaining and improving their skills. Respondents promoted searching services most frequently through orientations, brochures, and the libraries' Web pages. No respondent's institution mandated expert searching. Less than 2% of respondents' institutions had best practice guidelines related to expert searching, and only about 8% had guidelines or policies that identified situations where expert searching was recommended. CONCLUSIONS: The survey supports the belief that health sciences librarians still play a valuable role in searching, particularly in answering questions about treatment options and in providing education. It also highlights the need for more expert searching courses. There has been minimal discussion about the perceived need for expert-searching guidelines in the institutions represented by survey respondents. 相似文献

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel. 相似文献

Objectives:
The research objectives were to (1) describe the current and future roles of hospital librarians and the challenges they face and (2) find evidence supporting the hypothesis that librarians are essential to hospitals in achieving the organizations'' mission-critical goals.Method:
The authors used results from a previous research study that identified the five organizational mission-critical goals important to hospital administrators and then searched the literature and solicited examples from hospital librarians to describe the librarian''s role in helping hospitals achieve these goals.Results:
The literature supports the hypothesis that hospital librarians play important roles in the success of the hospital. Librarians support quality clinical care, efficient and effective hospital operations, continuing education for staff, research and innovation, and patient, family, and community health information needs.Conclusion:
Hospital librarians fulfill many mission-critical roles in today''s hospital, providing the right information at the right time in a variety of ways to enhance hospital and medical staff effectiveness, optimize patient care, improve patient outcomes, and increase patient and family satisfaction with the hospital and its services. Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.Highlights
- A review of the literature supports the hypothesis that services of the professional librarian result in:
- enhanced staff effectiveness,
- optimized patient care,
- improved patient outcomes, and
- increased patient and family satisfaction with the hospital and its services.
Implications
- Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

While most of Gramsci's party work is well known to education scholars of Gramsci, and the educational aspects of his writings have been repeatedly analyzed, what remains a constant in education-based Gramsci studies is the nearly universal minimization of this work for what it was, namely party work. For Gramsci, it would have been unthinkable to consider this work outside the framework of a revolutionary party. Yet, for contemporary educational scholars it seems unthinkable to consider Gramsci's work within the framework of a revolutionary party. The goals of this article are to outline Gramsci's interrelated conceptualization of the roles of the revolutionary party; the nature of education within and by the revolutionary party; and the aims of party education. For considerations of space, I limit this analysis to Gramsci's pre-prison praxis, the period of his active militancy in the PSI and the PCI. I conclude the article with what I consider to be lessons with continued relevance from Gramsci's praxis for the socio-political economic context faced by today's radical educators. 相似文献

The purpose of this study is to examine teachers' reflections of their early childhood special education work in Finnish day care. Work contents and work roles have faced many challenges in Early Childhood Special Education (ECSE), and therefore general reflection and research need to be developed. Teachers (n?=?218) evaluated, via an electronic survey, the work fields of ECSE. Reflectivity is assessed by means of open-ended questions in the different fields of ECSE. All the answers were divided into the following categories: the technical, practical, and critical level of reflection. The researchers compared their evaluations and found the baseline to be very similar. The data revealed that the reflectivity was mainly at the technical level. It was almost impossible to reach the critical reflection level. 相似文献

Objectives:
The purpose of the study was to assess the impact that funding from the National Network of Libraries of Medicine (NN/LM), Greater Midwest Region (GMR), has on member institutions'' ability to conduct outreach on behalf of NN/LM.Methods:
The study employed both content analysis and survey methodologies. The final reports from select GMR-funded outreach projects (n = 20) were analyzed based on a set of evaluation criteria. Project principal investigators (n = 13) were then surveyed using the same evaluation criteria.Results:
Results indicated that outreach projects supported by GMR funding improved access to biomedical information for professionals and the general public. Barriers to conducting outreach projects included time constraints or commitments, staffing, scheduling and absenteeism, inadequate space, and issues associated with technology (e.g., hardware and software, Internet connectivity and firewall issues, and creation and use of new technologies).Conclusions:
The majority of project principal investigators indicated that their attempts to conduct outreach were successful. Moreover, most noted that outreach had a positive impact on professionals as well as the general public. In general, it seems that negative outcomes, as with most barriers to conducting outreach, can be mitigated by more thorough planning.Highlights
- The provision of funding from the National Network of Libraries of Medicine (NN/LM), Greater Midwest Region (GMR), had a positive impact on an institution''s ability to conduct outreach.
- The provision of GMR funding to conduct health information outreach yielded positive outcomes.
Implications
- Regional offices should make efforts to accurately capture and record the impact that funding has on member institutions'' ability to conduct outreach.
- Many barriers to conducting outreach can be mitigated by more thorough planning.
- What did the institutions accomplish with the NN/LM funding?
- What outcomes did the institutions report from their NN/LM-funded outreach projects?
- What changes have been made in their institutional programs as a result of the funding they received?
- What lessons did the institutions learn through implementation of their NN/LM-funded outreach projects
- What changes would the institutions recommend to NN/LM about their funding programs?
