Meeting health information needs of people with HIV/AIDS: sources and means of collaboration

Background: Internet‐based applications, in particular those that allow communication, have great potential to meet information needs. Limited research has indicated that people with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS; PHAs) use these technologies, but it has not yet been examined how resources are used collaboratively and in conjunction with offline sources. Objectives: The purpose of this study was to determine in what ways PHAs collaborate to meet treatment information needs and what role Internet‐based computer‐mediated communication (CMC) played in meeting this goal. Methods: This exploratory study was implemented using surveys and focus groups with 23 participants in Toronto, Canada. The purposive sample included men and women. Results: A variety of both off‐ and online resources were used to learn about HIV/AIDS treatment information, including web‐based and print. All participants were communicating with others, primarily in person, and most desired anecdotal treatment information. However, few reported using CMC to accomplish this goal. Harris and Dewdney's Principles of Information Seeking was used to frame the findings. Conclusions: Despite technical proficiency with CMC, few participants in this study reported use of this communication tool. Information professionals need to ensure access to HIV health information including those in remote areas who have fewer resources.     

Assessing the Benefits of Content Notes Enhancements for Digital Audio Resources

Our library has previously investigated the potential impact the addition of contents notes on circulation. In a subsequent study, we found contents notes were the second metadata element most heavily linked to circulation (title was first). Since there has been a marked decline in the use of print resources at our library and a corresponding increase in digital resources, we wanted to know if the addition of contents notes to records for online streaming audio files would result in a similar increase in usage. After enhancing the records, we tracked usage for a period of three months.     

Narrative Capacity,Resistance Performance,and the “Shape” of New Social Movement Networks

The current research explored two new social movement networks in the United States in order to demonstrate the impact of narrative capacity on the “shape” of an activist network. In particular, we found that activists in a network that demonstrated efficient narrative capacity described the hub organization in positive terms, while activists in a network that demonstrated poor narrative capacity held mixed perceptions about the hub. Some activists in the second network held positive perceptions about the organization, while others held negative perceptions. The observations from these two research sites led us to conceptualize activists' differing perceptions about their respective hub organizations as “distance” that they experienced from that hub. Therefore, two different star shapes emerged from our research: a symmetrical star and elongated star. Such findings demonstrate the importance for narrative capacity in the construction and maintenance of effective activist networks.     

New Counselor Educators’ Scholarly Productivity: Supportive and Discouraging Environments

Eighteen new counselor educators shared in‐depth reports of their efforts to establish an early record of scholarly productivity, critical to their success in academe. Analyses of their experiences using consensual qualitative research methods revealed components of both highly positive and highly discouraging program environments and their impact on participants’ research goals.     

Countermovement jump performance assessment using a wearable 3D inertial measurement unit

The aim of this study was to validate a wearable inertial measurement unit (IMU), containing a 3D accelerometer and gyroscope, for the estimation of countermovement jump height. The absolute vertical acceleration of the IMU positioned on the back of the participant at L5 level, compensated for trunk rotations, was used to obtain jump height by applying the equation of free-fall to the motion of the IMU. The methodology was tested on 28 participants performing five countermovement jumps each. A reference value for this quantity was obtained using stereophotogrammetry (35.4 cm, s = 4.9). Jump height scores obtained using the proposed methodology (35.9 cm, s = 5.5) presented no significant difference with respect to stereophotogrammetry (P = 0.61). A low bias of 0.6 cm confirmed the accuracy of the estimate, which also showed a high (r = 0.87) and significant (P < 0.0001) correlation with reference values. Furthermore, without compensating accelerations for trunk rotation, jump height was largely underestimated (P < 0.0001) (bias: -12.7 cm) and poorly associated (r = 0.31) with stereophotogrammetry. The results of this study show that the estimation of jump height using inertial sensors leads to accurate results when the measured accelerations are corrected for trunk rotations.     

A color image segmentation method as used in the study of ancient monument decay

In the cultural heritage area, it is of fundamental importance to characterize and classify the conservation state of the materials constituting ancient monuments, in order to study and monitor their decay. Generally, the decay diagnosis is provided by “naked eye” analysis done by expert scientists “walking around” the artifact and recording the conservation state of each individual element they observe. In this paper, a color image segmentation approach, based on histogram threshold and edge detection techniques is presented, to extract degradation regions, characterized by holes or cavities, from color images of stone-materials. The goal is to provide an aid to the decay diagnosis by segmenting degraded regions from color images, computing quantitative data, such as the area and perimeter of the extracted zones, and processing qualitative information, such as various levels of depth detected into the same zones. Since color is a powerful tool in the distinction between objects, a segmentation technique based on color, instead of intensity only, has been used to provide a clearer discrimination between regions. The study case concerns the impressive remains of the Roman Theatre in the city of Aosta (Italy). In particular, we have processed and analyzed some color images of the theatre puddingstones, acquired by a camera.     

Adolescents' working models and styles for relationships with parents, friends, and romantic partners

This study examined the links among adolescents' representations of their relationships with parents, friends, and romantic partners. Sixty-eight adolescents were interviewed three times to assess their working models for each of these types of relationships. Working models of friendships were related to working models of relationships with parents and romantic partners. Working models of relationships with parents and romantic partners were inconsistently related. A similar pattern of results was obtained for self-report measures of relational styles for the three types of relationships. Perceived experiences were also related. Specifically, support in relationships with parents tended to be related to support in romantic relationships and friendships, but the latter two were unrelated. On the other hand, self and other controlling behaviors in friendships were related to corresponding behaviors in romantic relationships. Negative interactions in the three types of relationships also tended to be related. Taken together, the findings indicate that the representations of the three types of relationships are distinct, yet related. Discussion focuses on the nature of the links among the three.     

Children's literacy interest and its relation to parents’ literacy‐promoting practices

This study examined how children's literacy interests related to parent literacy‐promoting practices across time. Using a sample of 909 preschool‐age children and the newly developed Child Activities Preference Checklist, literacy interest appeared to be a complex construct, not easily captured by a single measure. In a subsample of 230 children with longitudinal data, parent literacy practices and child literacy interests related concurrently and across time. Parent literacy practices were more stable than child literacy interests, with children's literacy interest continuing to develop over the preschool year. Parent practices of exposing children to literacy and teaching them literacy concepts appeared to be distinct constructs. Exposure to literacy was especially important in the growth of literacy interests and the hypothesis that exposure has a negative effect on children with little initial interest was not fully supported.     

Applying a Software Development Product Cycle to Library Technology Adoption and Development

Product cycles have long been used in software development, but libraries can also benefit from a structured product life cycle to help manage technology development and acquisition. This article outlines a proposed product cycle for library technology management with information on implementing each step of the cycle. It will also include information for librarians assessing the success of structured technology management.
