Does (No) Discovery Lead to (ILL) Delivery? Comparing Transaction Logs to ILL Requests to Determine the Persistence of Library Patrons

This study looks at known-item searches within a university catalog that come up with a “no results” response to see whether patrons will then place an ILL request for that material and how persistent a user might be in order to obtain something that they want. Catalog search transaction logs were compared against interlibrary loan (ILL) requests placed during the same time frame. Overall, the rate of persistence, or the frequency with which ILL requests were placed when no results were found in the catalog is very low.     

Discovering User Behavior: Applying Usage Statistics to Shape Frontline Services

This investigation sought to develop a broad view of discovery service user behavior by analyzing vendor-provided and Google Analytics usage data from discovery service implementations at two Indiana University campuses. The results of this analysis demonstrate how usage data can communicate both intermediary and end results of user interactions within discovery services. The findings reveal user behavior trends, which may be used to develop strategies to improve information literacy instruction techniques, as well as discovery service interface enhancements.     

Forms of innovation inspired by open educational resources: a post-project analysis

It has been argued that Open Educational Resources (OER) present opportunities for innovation in education. However, there has been a lack of retrospective analysis of the forms of innovation that can emerge through OER, and the processes and challenges these entail. This paper presents a post-project analysis of the diverse uses and impacts of open courses produced through an international OER initiative. A thematic analysis of retrospective interviews and documentation from this case study is reported on, guided by a review of relevant concepts from innovation and OER literature. Through this we identify three archetypal forms through which the OER created opportunities for innovation: Specific Adoption; Preferred Practise and Foundations for Innovation. We identify drivers and inhibitors through which these forms of innovation interacted with each other in this initiative. This elaborates on the notion that a single existing model does not capture the multi-faceted relationships between innovation and OER.     

Let’s Clear the Air: a campaign that effectively increased compliance with a university’s tobacco-free policy

The purpose of this study was to assess the effectiveness of the Let’s Clear the Air campaign, a print-based campaign guided by the theory of planned behavior, designed to increase compliance with a University’s tobacco-free policy among undergraduate student smokers. We hypothesized that individual-level compliance behaviors would increase with greater campaign exposure and that population-level compliance would improve post-intervention from baseline. To assess individual-level compliance, we collected survey data from 284 randomly selected undergraduate student smokers. To assess population-level compliance, we collected observational data by counting smokers in 10 violation locations for 10 weeks (three 30-minute periods per week). Data supported the hypotheses: Campaign exposure was related to an increase in individual-level compliance behaviors, and results from a negative binomial regression supported that population-level compliance improved from baseline to post-intervention. Implications regarding support for the campaign as an effective strategy for increasing tobacco-free policy compliance behaviors are discussed.     

The Monty Hall Three Doors Problem

In this article, we study the Monty Hall three doors problem. A fully general solution and several new approaches are presented, including a Bayesian analysis.     

Carbohydrate gel ingestion during running in the heat on markers of gastrointestinal distress

The purpose of this study is to measure the effects of carbohydrate ingestion during exercise in the heat by measuring markers of gastrointestinal damage and inflammation. Methods: Active subjects (n?=?7) completed two 60-min running trials in a heated environment (70% VO₂max, 30°C). At minute 20 of exercise, subjects consumed a carbohydrate gel (Cho) (27?g), or a non-carbohydrate placebo (nCho). Plasma endotoxin, I-FABP, TNF-α, IL-6, IL-1β, IL-10, and MCP-1 were measured pre-exercise, 20-min post-exercise, and again 2-h, and 4-h post-exercise. Results: Endotoxin increased 20-min post-exercise compared to pre in the Cho trial only (p?=?.03). I-FABP levels increased 20-min post-exercise in the Cho trial only compared to pre-exercise (p?=?.003). I-FABP levels were also increased in Cho trial 20-min post-exercise when compared to same time point in the nCho trial (p?=?.032). TNF-α increased 20-min post-exercise in the Cho trial only compared to pre (p?=?.03). Plasma IL-6 concentration increased 20-min post-exercise when compared to pre in both the Cho (p?=?.002) and nCho (p?=?.009), but remained elevated at the 2-h time point in the nCho trial (p?=?.03). I-FABP and several plasma cytokines (TNF-α, MCP-1, Il-6) returned to baseline sooner in the Cho trial. Conclusions: Ingestion of carbohydrate gel during exercise in the heat enhances markers of gastrointestinal wall damage.
