Abstract:
ObjectiveThis metaresearch of the clinicaltrials.gov database aims to evaluate how clinical research on palliative care is conducted within the setting of advanced cancer.MethodsClinicaltrials.gov was searched to identify registered studies recruiting patients with cancer, and investigating issues relevant to palliative care. The European Organisation for Research and Treatment of Cancer QLQ-C15-PAL (Quality of Life in palliative cancer care patients) questionnaire was taken into account to define the research domains of interest. Studies investigating cancer-directed therapy, management of cancer treatment-related adverse events and diagnostic tests were excluded. Publication status was crosschecked using PubMed.ResultsOf 3950 identified studies, 514 were included. The most frequent reason for exclusion was cancer-directed therapy (2491). In 2007–2012, 161 studies were registered versus 245 in 2013–2018. Included studies were interventional (84%) or observational (16%). Most studies were monocentric (60%), sponsored by academia (79%), and conducted in North America (57%) or Europe (25%). Seventy-nine per cent of studies evaluated a heterogeneous population (>1 tumour type). Interventional studies most frequently investigated systemic drugs (34%), behavioural interventions (29%) and procedures for pain (24%). Pain, quality of life and physical function were the most frequently studied research domains (188, 95 and 52 studies, respectively). The most applied primary outcome measures were efficacy/symptom control (61%), quality of life (14%) and feasibility (12%). Only 16% of the closed studies had published results in PubMed.ConclusionsOur study describes the heterogeneous landscape of studies conducted to address the issues of patients with advanced cancer in palliative care. Albeit the observed increase in the number of studies over the last decade, the generalisation of the results brought by the existing trials is limited due to methodological issues and lack of reporting. A greater effort is needed to improve clinical research that supports evidence-based palliative cancer care.

Abstract:
As long as communication, especially digital communication, is of interest for consolidated fields such as sociology or political sciences and for fields of more recent creation such as librarianship, the field of communication research functions as an amnesic sub-discipline without disciplinary ambition (Pooley, 2020). In order to contribute to intellectually (re) constructing a field that can be useful to society, we are providing a typology of objectives, theoretical perspectives and methods generated from a distillation of volume 2 of Rethinking Communication (1989), “Paradigm Exemplars”, a volume specialized in meta-research in communication and considered as a continuation of the special volume of the Journal of Communication, "Ferment in the Field", published in 1983 (Surlin, 1991). The conceptual and procedural devices brought and grouped into those aimed at studying relationships between people and those aimed at studying relationships between people and media, are useful in a moment in which human relationships and relationships between people and media continue articulating societies, making necessary to review and redefine the ways of approaching them to further the scope of communication research, limited for decades, fundamentally, to the analysis of media content (Cáceres and Caffarel, 1992; Martínez-Nicolás and Saperas, 2011, 2016; Anderson and Middelton, 2015) through a content analysis that Krippendorff (2017) recommends to leave.

Abstract:
ObjectivesTo identify non-inferiority trials within a cohort where the experimental therapy is the same as the active control comparator but at a reduced intensity and determine if these non-inferiority trials of reduced intensity therapies have less favourable results than other non-inferiority trials in the cohort. Such a finding would provide suggestive evidence of biocreep in these trials.DesignThis metaresearch study used a cohort of non-inferiority trials published in the five highest impact general medical journals during a 5-year period. Data relating to the characteristics and results of the trials were abstracted.Primary outcome measuresProportions of trials with a declaration of superiority, non-inferiority and point estimates favouring the experimental therapy and mean absolute risk differences for trials with outcomes expressed as a proportion.ResultsOur search yielded 163 trials reporting 182 non-inferiority comparisons; 36 comparisons from 31 trials were between the same therapy at reduced and full intensity. Compared with trials not evaluating reduced intensity therapies, fewer comparisons of reduced intensity therapies demonstrated a favourable result (non-inferiority or superiority) (58.3%vs82.2%; P=0.002) and fewer demonstrated superiority (2.8%vs18.5%; P=0.019). Likewise, point estimates for reduced intensity therapies more often favoured active control than those for other trials (77.8%vs39.7%; P<0.001) as did mean absolute risk differences (+2.5% vs −0.7%; P=0.018).ConclusionsNon-inferiority trials comparing a therapy at reduced intensity to the same therapy at full intensity showed reduced effects compared with other non-inferiority trials. This suggests these trials may have a high rate of type 1 errors and biocreep, with significant implications for the design and interpretation of future non-inferiority trials.

Abstract:
The need for major information in meta-research (i.e. the part of medicine interested in systematic reviews [SRs] and meta-analyses [MAs]) is increasing. In the last years we are observing an exponential rate of publications as SRs/MAs in geriatric medicine. In order to better assess the interest in meta-research, we proposed a survey to know the knowledge and the needs in meta-research in geriatrics. A short survey (about 5 minutes) was freely available in the Italian Society of Hospital and Community Geriatrics (SIGOT) website and diffused in social networks. The survey was available during the entire 2019. The survey regards demographic information, previous research activities and the knowledge of the participant on meta-research. Altogether, 148 participants mainly men (=65.5%) and mainly aged 36 to 44 years and working in hospital from all Italian regions completed the survey. Responders read more than 20 articles in the previous year (=58.1%), including 10-20 SRs/MAs (25%). Many respondents (41.9%) had published >20 articles during their life. At the same time, a consistent part of the respondents recognized the importance of metaresearch for clinical practice and almost all the participants recognized that metaresearch has changed their daily clinical approach to the patient. Almost all the participants would like to have more training in meta-research suggesting that SIGOT should organize training courses for metaresearch in geriatric medicine. In conclusion, our survey showed that the interest in SRs/MAs is high, whilst the knowledge is still limited suggesting that education is needed to fill the gap in this field.

Abstract:
AbstractThis comment examines a threat to the development of law and psychology as a “public science” (i.e., one that goes beyond theory to address important issues in society), a failure to think critically about effect sizes. Effect sizes estimate the strength or magnitude of the relationship between variables and therefore can help decision makers understand whether scientific results are relevant to some legal or policy outcome. Accordingly, I suggest that those conducting and reporting law and psychology research should: (1) justify why observed effect sizes are meaningful and report them candidly and transparently, (2) scrutinize effect sizes to determine if they are plausible, and (3) plan studies such that they fit with the researchers’ inferential goals. I explore these points by way of case studies on influential law and psychology studies, such as implicit bias in the courtroom. I end with suggestions for implementing my recommendations, including a metaresearch agenda for law and psychology.

Abstract:
Research Doctorate - Doctor of Philosophy (PhD)
At present, in Australia, mediation is widely available through a range of publicly funded and supported mediation programs and services, most visibly in the court-connected context, and it is also available through industry programs as well as privately. The process has statutory acknowledgement in all jurisdictions, and mediators can be accessed through their membership of mediation panels, and of tribunals, or they can be appointed privately by disputants. Mediation enjoys a strong reputation for its dispute resolution efficacy, resting on at least forty years of research. The purpose of the research supporting this thesis was to establish what is known about mediator effectiveness and what makes a “good” mediator. The research analysed a selection of influential empirical studies of mediation and was conducted using a metaresearch framework, an approach that enables system-wide analysis and is uncommon in mediation research. Four research methodologies were applied: two thematic reviews, a systematic appraisal, a targeted review, and an online survey of professional mediators. The thesis argues that very little is known about mediator effectiveness, or about the role, actions, contributions, and influence of the mediator, because these remain largely unexplored. It argues further that very little can be known unless steps are taken to address the constraints on mediation research, including changes to publishing practices and the adoption of alternative research approaches and methods. This thesis contributes to mediation research, in particular empirical studies of mediation, by filling two knowledge gaps. It establishes that very little is known about mediator effectiveness and, taking a system-wide approach, it confirms reported constraints on mediation research.
