A validated search assessment tool: assessing practice-based learning and improvement in a residency program

Objective:

The objective of this study was to validate an assessment instrument for MEDLINE search strategies at an academic medical center.

Method:

Two approaches were used to investigate if the search assessment tool could capture performance differences in search strategy construction. First, data from an evaluation of MEDLINE searches from a pediatric resident''s longitudinal assessment were investigated. Second, a cross-section of search strategies from residents in one incoming class was compared with strategies of residents graduating a year later. MEDLINE search strategies formulated by faculty who had been identified as having search expertise were used as a gold standard comparison. Participants were presented with a clinical scenario and asked to identify the search question and conduct a MEDLINE search. Two librarians rated the blinded search strategies.

Results:

Search strategy scores were significantly higher for residents who received training than the comparison group with no training. There was no significant difference in search strategy scores between senior residents who received training and faculty experts.

Conclusion:

The results provide evidence for the validity of the instrument to evaluate MEDLINE search strategies. This assessment tool can measure improvements in information-seeking skills and provide data to fulfill Accreditation Council for Graduate Medical Education competencies.

Highlights

• The University of Michigan MEDLINE Search Assessment tool can be used to assess search skills in residency education.
• Five elements were identified as critical elements in the development of an effective MEDLINE search strategy: inclusion of all search concepts, appropriate use of Medical Subject Headings, appropriate use of search limits, successful combination of all concepts, and search efficiency.

Implications

• This validated assessment tool can serve as an effective means to measure improvements in residents'' information-seeking skills and provide data to fulfill Accreditation Council for Graduate Medical Education competencies.

     

Validation of MET estimates and step measurement using the ActivPAL physical activity logger

The purpose of this study was to determine the validity of the metabolic equivalent (MET) equation and step rate function of the ActivPAL? physical activity logger in a group of females. Using a standard treadmill protocol, 62 females aged 15-25 years walked on a treadmill at speeds between 3.2 and 7.0 km · h(-1) while wearing an ActivPAL. Oxygen consumption was measured using expired gas analysis at each speed and METs for each speed were estimated based on each participant's own resting metabolic rate. A sub-set of 18 participants also wore an Actigraph. Results showed that the in-built equation in the ActivPAL significantly underestimated (P < 0.001) METs under treadmill conditions at higher intensities. The ActivPAL equation is based on step rate yet the relationship between counts and measured METs (r = 0.76; P < 0.001) is stronger than that between steps and measured METs (r = 0.59; P < 0.001). Both the ActivPAL and Actigraph step functions showed no significant difference (P > 0.05) to video recorded step rate except at the slowest walking speed where the Actigraph significantly underestimated steps (P < 0.05). The development of a new equation based on the counts-METs relationship that includes a variety of speeds and activities would be useful. The ActivPAL step function performs better than the Actigraph at the slowest walking speed under treadmill conditions.     

The relationship between work conditions and perceptions of organizational justice among library employees

Library employees hold perceptions about the fairness of the outcomes, processes, and interpersonal treatment in their workplaces. When employees feel the workplace is fair they are more likely to feel commitment to the organization, perform in-role and extra-role tasks, and experience job satisfaction. When employees perceive injustice in the workplace, research points to negative outcomes such as withholding work or even sabotage. To understand the antecedents of organizational justice, researchers carried out a national survey of librarians to compare the predictive power of perceived organizational support, job autonomy, job feedback, and job stress. Results indicate that increasing librarians' perceptions of organizational support and their autonomy, and providing meaningful and timely job feedback can increase overall perceptions of justice. Managers can enhance a climate of justice in their workplaces by developing strategies that target organization support, autonomy, and feedback to reduce a sense of injustice between and among employees.

English for Scientific Purposes (EScP): Technology,Trends, and Future Challenges for Science Education

To date, the concept of English for Specific Purposes has brought about a great impact on English language learning across various disciplines, including those in science education. Hence, this review paper aimed to address current English language learning in the science disciplines through the practice of computer-assisted language learning to identify the use of learning technologies in science-based literacy. In the literature review, the researchers found that science-based literacy instruction shares many pedagogical aims with English language teaching in terms of reading, writing, listening and speaking, allowing it to be classified as English for Scientific Purposes (EScP). To answer the research questions, the researchers conducted the survey by extracting related articles and teaching examples from the Web of Science. In the search procedure, the researchers used the keywords science OR scientific AND technolog* OR comput* in ten selected journals of social science citation index. Only articles which are specified as journal articles rather than other document types were included. After compiling the corpora, the researchers compared the trends, methodologies and results of EScP instruction in science education. The implications of this study include the opportunities, advantages and challenges for EScP instruction in science education to further develop better educational approaches, adopt new technologies, as well as offer some directions for researchers to conduct future studies.     

On State Youth Policy in the Russian Federation

The social, economic, and cultural changes that occurred in Russia following the collapse of the Soviet Union have combine to impose sever damage on the population, and not least on Russia's young people. The provision of new forms of social and economic support are needed, as well as new youth programs, if further damage is to avoided.     

Why Doers Do—Part 3: External‐Intangible Elements of Human Performance

The externality‐tangibility model of human performance is a human performance technology (HPT) model that categorizes nine all‐inclusive elements of HPT into families of elements that can be external or internal to a performer and tangible or intangible. This third of three installments looks at the two factors that are external to a performer and are intangible: management and leadership. Applying the externality‐tangibility model consistently entails a six‐step process. There are limits to the externality‐tangibility model because it is focused on human performance and not on other factors of organization performance.
