Attitudinal effects of utilizing a critical method of analysis

Subjects were trained in the use of a critical method for analyzing controversial messages. At a later date the subjects, along with two control groups, listened to a counter‐attitudinal speech. Utilization of the critical method appeared to serve an immunizing function for females, while for males a heightened persuasibility effect was observed.     

THINKING ABOUT CITIZEN JOURNALISM

This study seeks to understand how community newspaper editors negotiate the professional complexities posed by citizen journalism—a phenomenon that, even in the abstract, would appear to undermine their gatekeeping control over content. Through interviews with 29 newspaper editors in Texas, we find that some editors either favor or disfavor the use of citizen journalism primarily on philosophical grounds, while others favor or disfavor its use mainly on practical grounds. This paper presents a mapping of these philosophical-versus-practical concerns as a model for visualizing the conflicting impulses at the heart of a larger professional debate over the place and purpose of user-generated content in the news production process. Moreover, these findings are viewed in light of gatekeeping, which, we argue, offers a welcome point of entry for the study of participatory media work as it evolves at news organizations large and small alike. In contributing to a growing body of literature on user-generated content in news contexts, this study points to the need for better understanding the causes and consequences of journalism's hyperlocal turn, as digitization enables newswork to serve increasingly niche geographic and virtual communities.     

The influence of hold regularity on perceptual-motor behaviour in indoor climbing

Climbers often train on indoor climbing walls, which are modifiable to simulate features of outdoor climbing environments at different levels of difficulty. The aim of this study was to evaluate the influence of regularity of climbing holds on emergent perceptual-motor behaviours. Skilled climbers performed six repetitions of two topographically similar routes on an indoor climbing wall. One route was composed of 18 different types of hand holds (irregular route), whereas the other route had only two types of hand holds (regular route). Preview and climbing durations, as well as visual search behaviours, were recorded. Participants rated the regular route as more difficult to climb, requiring greater perceived effort to complete. The time spent previewing, and then climbing the routes, was reduced on average by 12% and 16%, respectively in the irregular route compared to the regular route. There were more fixations made when climbing the regular route (281 vs. 222 fixations per trial). It seems the climbers were more careful and thorough in their gaze behaviours with the regular route because of the additional technical demands it presented, whereas the irregular route afforded a more superficial visual exploration with use of more frequent saccades between holds. The findings suggest how irregularity in the environment is exploited by skilled climbers, apparently making the practice context easier to perceive and act in.     

Assessing Learning across Pedagogical Modalities and Learning Retrieval Conditions for College Learners in Introductory Psychology

The present study attempted to explore if learning is as effective in the web-based platform as it is in the traditional or web-enhanced modalities. Unlike prior studies that measured learning using course grades and subjective student reporting, this study used an empirical method to develop a valid and reliable measure of learning. Data from 346 college students participating in an introductory psychology course were compared across the three instructional modalities. Consistent with prior research, the results revealed no significant differences on a measure of learning effectiveness between the three learning modalities. Additional analysis of the results was conducted based on the ‘specificity of encoding’ model and indicated that students who retrieved the information in a context congruent with where encoding took place scored significantly lower than those who retrieved the information in an incongruent context. Whereas prior models of learning placed the encoding of information squarely in the classroom context, these results suggested that encoding takes place primarily in the cyber online context. This reconceptualization of the context of encoding suggests that congruous context for encoding and retrieval is when both processes reside in the cyber online context.     

Microstructural analysis of conditioned and unconditioned responses to maltodextrin

The microstructure of licking responses was analyzed to investigate the interaction between unconditioned responses to maltodextrin and the responses to flavor cues previously associated with maltodextrin. Experiment 1 demonstrated that although the consumption of maltodextrin peaked at intermediate concentrations, the mean lick cluster size showed a positive, monotonic increase with concentration. In Experiment 2, a (conditioned stimulus) CS+ flavor was paired with 16% maltodextrin, whereas a CS- flavor was paired with 2% maltodextrin. During test, consumption of the CS+ was higher than that of the CS- when the flavors were combined with 2% maltodextrin, but not when combined with 16% maltodextrin. In contrast, cluster size was larger with the CS+ than with the CS-, regardless of the concentration of maltodextrin present on test. Previous analyses of licking microstructure indicate that cluster size reflects the palatability of the ingested solution. Thus, the present results indicate that flavor conditioning can change the palatability of the cue flavors. Adding the CS+ flavor to maltodextrin produced results analogous to increasing the concentration of maltodextrin (in terms of both consumption and licking microstructure measures), which is consistent with the idea that after conditioning, responses to the CS+ flavor and to the unconditioned stimulus are mediated via the same representation.     

Thinking with Posthuman Perspectives in Self-Study Research

In this study, we set out to explore processes of individual and group becomings of a self-study collective over time and distance, and with/through technology. Born out of a self-study project in one of our early doctoral courses, our self-study community has evolved over several years to one that is hybrid in nature. As we have continued our collaboration through online media, a tension arose at the juncture of our fundamentally relational work together, our need for the physical, embodied aspect of learning and self-study and the hybrid, often disembodied, experience provided by substituting online meetings for those conducted in-person. In this article we explore these tensions through pivotal moments and lines of flight in our self-study work over the past year. To frame these moments, we draw on ideas from posthumanism, which offers ways to conceptualize our collective as a multiplicity, account for the relational and material aspects of our work, address the agency of non-human actors (such as technology) in our collaboration, and consider our self-study practice a dynamic, complex, contextualized, situated phenomenon.     

Developing a generic tool to routinely measure the impact of health libraries

Background

Health libraries contribute to many activities of a health care organisation. Impact assessment needs to capture that range of contributions.

Objectives

To develop and pilot a generic impact questionnaire that: (1) could be used routinely across all English NHS libraries; (2) built on previous impact surveys; and (3) was reliable and robust.

Methods

This collaborative project involved: (1) literature search; (2) analysis of current best practice and baseline survey of use of current tools and requirements; (3) drafting and piloting the questionnaire; and (4) analysis of the results, revision and plans for roll out.

Findings

The framework selected was the International Standard Methods And Procedures For Assessing The Impact Of Libraries (ISO 16439). The baseline survey (n = 136 library managers) showed that existing tools were not used, and impact assessment was variable. The generic questionnaire developed used a Critical Incident Technique. Analysis of the findings (n = 214 health staff and students), plus comparisons with previous impact studies indicated that the questionnaire should capture the impact for all types of health libraries.

Conclusions

The collaborative project successfully piloted a generic impact questionnaire that, subject to further validation, should apply to many types of health library and information services.
