The purpose of this study was to understand factors that may affect the usage of a consumer health center located in a public library. More specifically, the authors wanted to know what health resources are of interest to the community, what patrons'' perceptions of their experience at the center are, and finally, how staff can increase utilization of the center. In general, perceptions of the center were positive. The findings support that participants appreciate efforts to provide health information in the public library setting and that utilization could be improved through marketing and outreach.Problems with health literacy—one''s ability to obtain, process, and understand basic information and services needed to make appropriate health decisions 1, 2—significantly limit effective dissemination and understanding of relevant health information, especially among racial and ethnic minorities where health literacy challenges are pervasive 35. People with limited health literacy skills have higher medical costs and use an inefficient mix of medical services 3, 613. This compromises their health and is a major source of economic inefficiency in the US health care system. Efforts to address low health literacy may result in reductions of health inequities, decreased medical costs, and enhanced quality of life 14. However, efforts to promote health literacy that seek to empower individuals to understand health information and act in their own interest remain an underexplored pathway to improved health outcomes 9.The National Network of Libraries of Medicine (NN/LM) encourages libraries to reach out to low literacy groups in their surrounding communities to address literacy challenges 1517. These actions have resulted in development of consumer health libraries, centers where patrons can get accurate and timely health information. Preliminary investigations of consumer health libraries have reinforced the value of these services 18, 19, but there is little information regarding the provision of similar services in other public settings.The Healthy Living and Learning Center (HLLC), located in a public library in Petersburg, Virginia, was established in 2012 to provide one-on-one assistance in accessing health information and community resources. According to 2010–2013 census data, 25% of Petersburg residents are below the poverty line 20. Localities surrounding the HLLC experience some of the most unfavorable health outcomes in Virginia 21. In addition, 16%–24% of citizens in the surrounding localities are illiterate 22.The public library setting provides an appropriate context to initiate consumer health centers outside of medical settings. Librarians are already being asked to meet consumer demands for health information 1517, and the provision of accurate health information is a natural extension of the services that public libraries provide. The American Library Association reports that 62% of libraries report that they are the only source of free public access to computers and the Internet in their communities 23. According to a recent study from Pew, 35% of Americans 16 and older say they have used free Internet access points, 47% of whom have used these services to get health information 24. For a number of minorities, the public library is the only place they have Internet access 25. Thus, libraries not only remain a critical resource among the public, but may also have unique access to populations who are more vulnerable to health inequities.  相似文献

The Terra Populus project (TerraPop) addresses a variety of data management, curation, and preservation challenges with respect to spatiotemporal population and environmental data. In this article, we describe our approaches to these challenges, with a particular focus on geospatial data workflows and associated provenance metadata. The goal of TerraPop is to enable research, learning, and policy analysis by providing integrated spatiotemporal data describing people and their environment. To do so, TerraPop is assembling a globe-spanning and temporally extensive collection of high-quality population and environmental data, ensuring good documentation, and developing a Web-based data access system that enables users to assemble customized integrated data sets drawing on a variety of data sources and formats. We describe TerraPop's collection strategies, detail the geospatial workflows involved in preparing data for ingest into the project database and those used to transform data across formats for dissemination, and discuss the system used to capture and manage provenance metadata throughout the project. A key aspect of the project is the development of global current and historical administrative unit boundaries that can be linked to census data. These boundaries serve as the linchpin of TerraPop's data integration strategy, and constitute an important data set in their own right.  相似文献

Earth science education, as it is traditionally taught, involves presenting concepts such as weathering, erosion, and deposition using relatively well-known examples—the Grand Canyon, beach erosion, and others. However, these examples—which resonate well with middle- and upper-class students—ill-serve students of poverty attending urban schools who may have never traveled farther from home than the corner store. In this paper, I explore the use of a place-based educational framework in teaching earth science concepts to urban fifth graders and explore the connections they make between formal earth science content and their lived experiences using participant-driven photo elicitation techniques. I argue that students are able to gain a sounder understanding of earth science concepts when they are able to make direct observations between the content and their lived experiences and that when such direct observations are impossible they make analogies of appearance, structure, and response to make sense of the content. I discuss additionally the importance of expanding earth science instruction to include man-made materials, as these materials are excluded traditionally from the curriculum yet are most immediately available to urban students for examination.  相似文献

Building on previous research in which we provided an opportunity for female college athletes to construct their own photographic portrayals, this study explored young female athletes' perceptions of the college athlete photographs. Fifty-two girls participated in focus group interviews where they viewed and discussed the images. The young athletes particularly liked images they perceived to show authentic athletes (e.g, in athletic settings, with appropriate sport attire), images they could relate to due to personal experiences, and images that reflected competent and passionate sportswomen. Images perceived as revealing a lack of motivation, poor sporting attitudes, and nonathletic poses generally were disliked. Images depicting multiple social identities (e.g., an athlete in a dress) were controversial and generated much discussion.  相似文献

We draw upon transformational leadership theory to develop an instrument to measure transformational parenting for use with adolescents. First, potential items were generated that were developmentally appropriate and evidence for content validity was provided through the use of focus groups with parents and adolescents. We subsequently provide evidence for several aspects of construct validity of measures derived from the Transformational Parenting Questionnaire (TPQ). Data were collected from 857 adolescents (M(age) = 14.70 years), who rated the behaviors of their mothers and fathers. The results provided support for a second-order measurement model of transformational parenting. In addition, positive relationships between mothers' and fathers' transformational parenting behaviors, adolescents' self-regulatory efficacy for physical activity and healthy eating, and life satisfaction were found. The results of this research support the application of transformational leadership theory to parenting behaviors, as well as the construct validity of measures derived from the TPQ.  相似文献

Past research in calculus education has shown that Riemann sum-based conceptions of the definite integral, such as the multiplicatively based summation (MBS) conception, can have important value in interpreting and making sense of certain types of definite integral expressions. However, additional research has shown that students tend to not draw on the MBS conception, even in situations where it would be advantageous to do so. In this study we examine how introductory instruction on integration, in which explicit attention is given to the Riemann sum and Riemann integral, may be related to students’ tendency to not use the MBS conception. In particular, it appears that some calculus instructors may make instructional moves in their classrooms that directly undermine the time the instructors had spent developing the Riemann sum and Riemann integral concepts. In doing so, students may perceive these concepts only as calculational procedures, rather than as a potential source of conceptual meaning.  相似文献

Attention-deficit/hyperactivity disorder (ADHD) was previously believed to be a disorder of childhood, with symptoms attenuating at the onset of puberty. Follow-up studies, however, suggest that the majority of children with ADHD continue to manifest symptoms into adulthood. Although the inattention components associated with ADHD persist into adulthood, the nature of the hyperactivity component is less well understood. For example, according to criteria established by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, hyperactivity in adolescents and adults may be limited to subjective feelings of restlessness. Recent studies with adults with ADHD have also reported that mental restlessness is commonly reported by individuals with the disorder. To better understand this characteristic of ADHD, the Internal Restlessness Scale (IRS) was developed. The results of the IRS suggest that (a) college students with ADHD report significantly higher ratings of internal restlessness than college students without ADHD, and (b) the IRS appears to have adequate test-retest reliability and a four-factor structure. Implications and suggestions for future research are discussed.  相似文献

Theory of mind and relational complexity   总被引:5,自引:0,他引:5  
Cognitive complexity and control theory and relational complexity theory attribute developmental changes in theory of mind (TOM) to complexity. In 3 studies, 3-, 4-, and 5-year-olds performed TOM tasks (false belief, appearance-reality), less complex connections (Level 1 perspective-taking) tasks, and transformations tasks (understanding the effects of location changes and colored filters) with content similar to TOM. There were also predictor tasks at binary-relational and ternary-relational complexity levels, with different content. Consistent with complexity theories: (a) connections and transformations were easier and mastered earlier than TOM; (b) predictor tasks accounted for more than 80% of age-related variance in TOM; and (c) ternary-relational items accounted for TOM variance, before and after controlling for age and binary-relational items. Prediction did not require hierarchically structured predictor tasks.  相似文献
