This thesis reports on a study undertaken at the Dixson Library, University of New England. The purpose of the study was to develop an understanding of users of online public access catalogues (OPACs). The understanding gained from the study will assist in the development of improvements to the Library's OPAC, and increase user ability to access information from the OPAC. The study replicated the user questionnaire of the Online Patron Access Project, sponsored by the Council on Library Resources (CLR) in 1981/83. The questionnaire was modified slightly to suit conditions at the Dixson Library. The study addressed nine research questions relating to the users, their reactions, attitudes, experiences and problems. The user task and their suggestions for improvement were also addressed. The study formally tested three propositions between the variables user task, success and attitudes in relation to OPAC users. The findings show the analysis of the responses for the population as a whole, and, where relevant, for eight groups of student respondents based on their academic affiliation. The student population was of particular importance because of the preponderance of external students at the University of New England. The differences in the findings between the groups of students were discussed, and where possible, explained. The three formal propositions were tested by carrying out Chi square tests for the values of each variable. Nine significant relationships were found. Comparisons were made between the Dixson Library findings and those of the CLR study. Recommendations and conclusions were drawn from the study, including areas for further research.

Objectives: Among different factors, diet patterns seem to be related to depression. The aim of this study was to evaluate the association between the consumption of fruits and/or vegetables and depressive symptoms. Methodology/Principal findings: A secondary data analysis was conducted using information from a population-based survey from 25 regions from Peru. The outcome was the presence of depressive symptoms according to the Patient Health Questionnaire (cutoff 15 to define major depressive syndrome); whereas the exposure was the self-reported consumption of fruits and/or vegetables (in tertiles and using WHO recommendation 5 servings/day). The association of interest was evaluated using Poisson regression models controlling for the complex-sample survey design and potential confounders. Data from 25,901 participants were analyzed, mean age 44.2 (SD: 17.7) and 13,944 (54.0%) women. Only 910 (3.8%; 95%CI: 3.5%–4.2%) individuals reported consuming 5 servings of fruits and/or vegetables/day; whereas 819 (2.8%; 95%CI: 2.5%–3.1%) had depressive symptoms. Those in the lowest tertile of fruits and/or vegetables consumption had greater prevalence of depressive symptoms (PR = 1.88; 95% CI: 1.39–2.55) than those in the highest tertile. This association was stronger with fruits (PR = 1.92; 95%CI: 1.46–2.53) than vegetables (PR = 1.42; 95%CI: 1.05–1.93) alone. Conclusions: An inverse relationship between consumption of fruits and/or vegetables and depressive symptoms is reported. Less than 5% of subjects reported consuming the amount of fruits and vegetables recommended by the WHO. There is a need to implement strategies to promote better diet patterns with potential impact on mental health. © 2017 Wolniczak et al.
