    Cross-Dictionary Linking at Sense Level with a Double-Layer Classifier

    We present a system for linking dictionaries at the sense level, which is part of a wider programme aiming to extend current lexical resources and to create new ones by automatic means. One of the main challenges of the sense linking task is the existence of non one-to-one mappings among senses. Our system handles this issue by addressing the task as a binary classification problem using standard Machine Learning methods, where each sense pair is classified independently from the others. In addition, it implements a second, statistically-based classification layer to also model the dependence existing among sense pairs, namely, the fact that a sense in one dictionary that is already linked to a sense in the other dictionary has a lower probability of being linked to a further sense. The resulting double-layer classifier achieves global Precision and Recall scores of 0.91 and 0.80, respectively

    A Comprehensive Summary of Services and Resources Provided by Librarians in support of CODA Accredited Predoctoral (DDS/DMD) Dental Education Programs in the United States and Canada

    Objective The objective of this study is to provide a summary of library services and resources that support dental education and research. This summary will demonstrate trends in dental librarianship as well as services and resources that can be adopted to serve the needs of dental related education programs. To date, there has not been a comprehensive summary of these services. Methods An environmental scan was carried out to take inventory of services that dental librarians (1) provide. The study population consisted of librarians who work in dental libraries or college / university libraries that serve dental programs. The librarians surveyed were from institutions with a CODA accredited DMD/DDS pre-doctoral program (2). Currently, there are 76 such programs within the United States and Canada, of which 71 responded. Conclusion Our data demonstrates that the majority of dental programs have a dedicated librarian or library liaison providing clinical, educational, and research support through a variety of approaches. Increasing awareness and utilization of available services and resources within the dental community can facilitate research and complement dental education. The service models cited here can be adapted in dental related education programs across North America

    Background:Recruitment challenges contribute to the paucity of palliative care research with advanced chronic heart failure patients.Aim:To describe the challenges and outline strategies of recruiting advanced chronic heart failure patients.Design:A feasibility study using a pre–post uncontrolled design.Setting:Advanced chronic heart failure patients were recruited at two nurse-led chronic heart failure disease management clinics in IrelandResults:Of 372 patients screened, 81 were approached, 38 were recruited (46.9% conversion to consent) and 25 completed the intervention. To identify the desired population, a modified version of the European Society of Cardiology definition was used together with modified New York Heart Association inclusion criteria to address inter-study site New York Heart Association classification subjectivity. These modifications substantially increased median monthly numbers of eligible patients approached (from 8 to 20) and median monthly numbers recruited (from 4 to 9). Analysis using a mortality risk calculator demonstrated that recruited patients had a median 1-year mortality risk of 22.7 and confirmed that the modified eligibility criteria successfully identified the population of interest. A statistically significant difference in New York Heart Association classification was found in recruited patients between study sites, but no statistically significant difference was found in selected clinical parameters between these patients.Conclusion:Clinically relevant modifications to the European Society of Cardiology definition and strategies to address New York Heart Association subjectivity may help to improve advanced chronic heart failure patient recruitment in clinical settings, thereby helping to address the paucity of palliative care research this population

    Mapping staff perspectives towards the delivery of hospital care for children and young people with and without learning disabilities in England : a mixed methods national study

    Background Children and young people (CYP) with learning disabilities (LD) are a vulnerable population with increased risk of abuse and accidental injury and whose parents have reported concerns about the quality, safety and accessibility of their hospital care. The Care Quality Commission’s (CQC) view of best practice for this group of patients includes: access to senior LD nurse provision; a clearly visible flagging system for identifying them; the use of hospital passports; and defined communication strategies13. What remains unclear is whether these recommendations are being applied and if so, what difference they are making. Furthermore, what we do not know is whether parental concerns of CYP with LD differ from parents of other children with long-term conditions. The aims of this study were to 1) describe the organisational context for healthcare delivery to CYP with LD and their families and 2) compare staff perceptions of their ability to identify the needs of CYP with and without LD and their families and provide high quality care to effectively meet these needs. Methods Individual interviews (n=65) and anonymised online survey (n=2261) were conducted with hospital staff working with CYP in 15 children’s and 9 non-children’s hospitals in England. The majority of interviews were conducted over the telephone and recorded and transcribed verbatim. Ethics approval was obtained and verbal or written consent for data collection was obtained from all interview participants. Results The nature and extent of organisational policies, systems and practices in place within hospitals to support the care of CYP with LD differs across England and some uncertainty exists within and across hospitals as to what is currently available and accessed. Staff perceived that those with LD were included less, valued less, and less safe than CYP without LD. They also reported having less confidence, capability and capacity to meet the needs of this population compared to those without LD. Conclusion Findings indicate inequality with regards the provision of high quality hospital care to children and young people with intellectual disabilities that meets their needs. There is a pressing need to understand the impact this has on them and their families.</p

    The QuinteT Recruitment Intervention supported five randomized trials to recruit to target: a mixed-methods evaluation

    ObjectiveTo evaluate the impact of the Quintet Recruitment Intervention (QRI) on recruitment in challenging randomized controlled trials (RCTs) that have applied the intervention. The QRI aims to understand recruitment difficulties, and then implements ‘QRI-actions’ to address these as recruitment proceeds.Study Design and SettingA mixed-methods study, comprising: a) before-and-after comparisons of recruitment rates and numbers of patients approached, and b) qualitative case studies, including documentary analysis and interviews with RCT investigators.ResultsFive UK-based publicly-funded RCTs were included in the evaluation. All recruited to target. RCT2 and RCT5 both received up-front pre-recruitment training before the intervention was applied. RCT2 did not encounter recruitment issues and recruited above target from its outset. Recruitment difficulties, particularly communication issues, were identified and addressed through QRI-actions in RCTs 1, 3, 4 and 5. Randomization rates significantly improved post-QRI-action in RCTs 1,3, and 4. QRI-actions addressed issues with approaching eligible patients in RCTs 3 and 5, which both saw significant increases in patients approached. Trial investigators reported that the QRI had unearthed issues they had been unaware of, and reportedly changed their practices post QRI-action.ConclusionThere is promising evidence to suggest the QRI can support recruitment to difficult RCTs. This needs to be substantiated with future controlled evaluations
