E-textbooks are now widely available and accessible to students offering them distinct advantages over print books at lower costs. However the uptake of e-textbooks has been slow and student preferences for either medium are not well understood. This study adopts a qualitative approach using an expectation-confirmation theory (ECT) lens and revealed causal mapping to understand from students participating in focus groups, their intentions to continue using etextbooks. We extend ECT by including two new constructs: perceived quality and perceived value. The results assist in interpreting students' behavior regarding intentions to continue using e-textbooks and the efficacy of the extended ECT model.

Design/methodology/approach – A web-based survey was distributed to all UNSW academics in medicine, and 224 completed responses were analyzed according to the attributes of a task-technology fit (TTF) model developed for e-books in academic settings. Findings – Although the UNSW Library had access to > 225,000 e-books, usage by medical academics was relatively low (38 per cent); however, most (92 per cent) predicted that they would be using e-books within the next five years. Nearly two-thirds (65 per cent) had portable devices including smartphones, and 90 per cent rated the ability to search across full text in an e-book of moderate-to-high importance. Research tasks dominated the use of e-books, and 71 per cent agreed that e-books helped improve their overall productivity. Research limitation/implications – Only 224 (8 per cent) of 2,790 medical academics at UNSW participated in the study. The low response rate and over-representation of research only academics limit the extent of generalization of the findings. Originality/value – This is the first study on the use of e-books among academics in the Faculty of Medicine – comprising nearly 64 per cent of all UNSW academic staff. The findings highlight the extent of e-books used by medical academics and their enthusiasm for access to digital resources. There is also the suggestion that the library must continue to develop services to ensure delivery of task-compatible e-books to medical academics in increasingly mobile environments.

This study charts the evolution of the B/P literature published during the last 30 years. Using various searching techniques, 189 B/P studies published from 1993 to August 2022 were collected for analysis—half were published since 2018. Most of the selected B/P publications use classic bibliometric analysis of Pain in toto, while some focus on specific types of Pain with Headache/Migraine, Low Back Pain, Chronic Pain, and Cancer Pain dominating. Each study is characterized by the origin (geographical, economical, institutional, …) and the medical/scientific context over a specified time span to provide a detailed landscape of the Pain research literature. Some B/P studies have been developed to pinpoint difficulties in appropriately identifying the Pain literature or to highlight some gen...

Research papers on AD published from 1983 to 2017 in journals indexed in the Web of Science were analyzed in seven five-year periods. The number of AD papers increased from 1,095 in 1983-1987 to 50,532 by 2013-2017 and in the same time period, the number of participating countries went from 27 to 152. The US was the most prolific country throughout, followed by several European countries, Canada, Australia, and Japan. Asian countries have emerged and by 2013-2017, China surpassed all but the US in productivity. Countries in Latin America and Africa have also contributed to AD research. Additionally, several new non-governmental institutions (e.g., ADNI, ADI) have emerged and now play a key role in the fight against AD. Likewise the AD scientific publishing universe evolved in various aspects: an increase in number of journals containing AD papers (227 journals in 1983-1987 to 3,257 in 2013-2017); appearance of several AD-focused journals, e.g., Alzheimer's & Dementia, Journal of Alzheimer's Disease; and the development of special issues dedicated to AD. Our paper complements the numerous extant papers on theoretical and clinical aspects of AD and provides a description of the research landscape of the countries and journals contributing papers related to AD.

The positive effect on the condition of the vascular wall in the treatment of hypertension was proven by using calcium channel blockers and fixed combination of angiotensin-converting-enzyme inhibitor with a thiazide-like diuretic. Methods: The study included 121 patients with hypertension of both genders (mean age 49,3±5,9 years). Three groups were formed: group 1 (n= 32) treated by amlodipine 5-10 mg, group 2 (n= 44) treated by fixed combination perindopril 4 mg and indapamide 1.25 mg, group 3 (n= 45) treated by another adequate antihypertensive therapy. We evaluated the indicators of pulse wave velocity (PWV) on vessels elastic (PWVe) and muscular (PWVm) types, duplex scanning of the carotid arteries and echocardiography during therapy. Results: A decrease in the mean values of PWVe (p< 0,05) was measured in all three groups of patients after 6 months of therapy, but more so in the first group. Decrease of PWVe to 17% and 16,5% from the baseline was observed in the first and second groups, respectively in the third it was less pronounced (10,1%) after 12 months of treatment. The most pronounced decrease in PWVm was observed in the first (P< 0,001) and second (P< 0,05) groups of patients after 6 months of treatment while in the third group no decrease was witnessed (P> 0,05). The thickness of the intima-media complex has decreased by 10,1% (P< 0,05) after 6 months of amlodipine treatment. After 12 months of treatment in the second and the third group significant dynamics of reverse development of left ventricular remodeling (P< 0,05) was marked. Conclusions: The parallelism of the results suggests that the improvement in the elastic properties of large vessels occur during antihypertensive therapy due to structural changes.

Aim: To provide preliminary results of the psychometric evaluation of the Spanish version of the NPSI. Methods: 548 patients with moderate to severe (NPSI total score ≥ 50) NP (pure or combined) were evaluated in a twostage epidemiologic survey. Evaluations, separated by 60 days, included the NPSI, the Neuropathic Pain Questionnaire-Short Form (NPQ) and the Neuropathic Pain Scale (NPS). Analyses included principal component analysis with varimax rotation, calculation of standardized Cronbach’s alpha (aS) coefficients for total and factor scores to assess internal consistency, and the area under the ROC curve (AURC) versus the discriminant function score of the NPQ and a 30% reduction of total NPS score to evaluate responsivity. Analyses of construct validity are in progress. Results: The Spanish items of NPSI had very good global (aS = 0.90) and factor (evoked pain aS = 0.80, pressive pain aS = 0.82, paroxysmal pain aS = 0.76, abnormal sensations aS = 0.87) internal consistence. The original factor structure was reproduced, albeit the electric shocks item showed also a relevant factorial load within the (original) single-item burning pain factor. Responsivity was also good, with AURC values of 0.86 and 0.85 versus the NPQ and NPS, respectively. Discussion: The Spanish NPSI is reliable, valid, and comparable to its original version.

Journal publications (with at least one Australian author) of the cancer literature from Science Citation Index and Social Sciences Citation Index were analyzed. For the five-year period, New South Wales (NSW) produced the most publications (31%), slightly ahead of Victoria (VIC) with 29%; Queensland (QLD) ranked third (14%) and South Australia (SA) fourth with 11%. However, as measured by mean journal impact factor, the publications from NSW were of overall lower quality than those from VIC, SA, QLD, and from Australia as a whole. When standardized for quality against the national average, and adjusted for state size, the publication output of the four larger states are ranked in order: SA >> VIC >> QLD > NSW. Four measures of international collaboration on publications were investigated ...

Dedicated e-readers and other smart devices are integral to e-books offering affordances to overcome the physical limitations of print book and to provide the functionality of information technology. Using netnography, comments by online readers to articles in The New York Times and Scientific American were analysed and coded by themes identified in the literature of e-books versus print books. An Affordance Theory approach was used to provide insights into the readers' perceptions of real and actual affordances and the value delivered by these affordances. Comments by online readers of two diverse datasets confirm results found in questionnaires and surveys reported in the academic literature. It is the physical attributes and functionality of smart devices used in e-reading that provides the opportunity of affordance. Our study provides support for an affordance perspective of e-books and e-readers. It also highlights preferences for e-books and/or print books in various contexts. To our knowledge it is the first to consider e-readers as an IT artefact providing information processing capabilities.

These aspects are: inclusion of publications in databases, publications in journals, authorship characteristics of publications, productivity, and subject content of publications over time. Results indicate that national and LIS-specific databases provided adequate coverage; however, no single database provided over half of all publications. More than half of all articles were published in national journals focusing on aspects of LIS in Australia; however, there is a trend for increasing publications in international journals. Most of the earlier publications had one author, but multiple authorship in publications has increased since 1999. Overall the number of publications per LIS academic is low; however, per capita productivity has been increasing since the mid...
