Improved mutual fund investment choice architecture

Two choice architecture interventions were explored to debias investors’ irrational preference for mutual funds with high past returns rather than funds with low fees. A simple choice task was used involving a direct trade-off between maximizing past returns and minimizing fees. In the first intervention, warning investors that, “Some people invest based on past performance, but funds with low fees have the highest future results” was more effective than three other disclosure statements, including the US financial regulator’s, “Past performance does not guarantee future results”. The second intervention involved converting mutual fund annual percentage fees into a 10 year dollar cost equivalent. This intervention also improved investors’ fee sensitivity, and remained effective even as past returns increased. Financially literate participants were surprisingly more likely to irrationally maximize past returns in their investment choices

Influential Article Review- Effects of the Open Collaboration Workspace

This paper examines interaction in workspace We present insights from a highly influential paper. Here are the highlights from this paper: Organizations’ pursuit of increased workplace collaboration has led managers to transform traditional office spaces into ‘open’, transparency-enhancing architectures with fewer walls, doors and other spatial boundaries, yet there is scant direct empirical research on how human interaction patterns change as a result of these architectural changes. In two intervention-based field studies of corporate headquarters transitioning to more open office spaces, we empirically examined— using digital data from advanced wearable devices and from electronic communication servers—the effect of open office architectures on employees' face-to-face, email and instant messaging (IM) interaction patterns. Contrary to common belief, the volume of face-to-face interaction decreased significantly (approx. 70%) in both cases, with an associated increase in electronic interaction. In short, rather than prompting increasingly vibrant face-to-face collaboration, open architecture appeared to trigger a natural human response to socially withdraw from officemates and interact instead over email and IM. This is the first study to empirically measure both face-to-face and electronic interaction before and after the adoption of open office architecture. The results inform our understanding of the impact on human behaviour of workspaces that trend towards fewer spatial boundaries. This article is part of the theme issue ‘Interdisciplinary approaches for uncovering the impacts of architecture on collective behaviour’. For our overseas readers, we then present the insights from this paper in Spanish, French, Portuguese, and German

Evaluation of the accuracy of bacterial genome reconstruction with Oxford Nanopore R10.4.1 long-read-only sequencing

Whole genome reconstruction of bacterial pathogens has become an important tool for tracking transmission and antimicrobial resistance gene spread, but highly accurate and complete assemblies have largely only historically been achievable using hybrid long and short-read sequencing. We previously found the Oxford Nanopore Technologies (ONT) R10.4/kit12 flowcell/chemistry produced improved assemblies over the R9.4.1/kit10 combination, however long-read only assemblies contained more errors compared to Illumina-ONT hybrid assemblies. ONT have since released an R10.4.1/kit14 flowcell/chemistry upgrade and recommended the use of Bovine Serum Albumin (BSA) during library preparation, both of which reportedly increase accuracy and yield. They have also released updated basecallers trained using native bacterial DNA containing methylation sites intended to fix systematic basecalling errors, including common adenosine (A) to guanine (G) and cytosine (C) to thymine (T) substitutions. To evaluate these improvements, we successfully sequenced four bacterial reference strains, namely Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus, and nine genetically diverse E. coli bloodstream infection-associated isolates from different phylogroups and sequence types, both with and without BSA. These sequences were de novo assembled and compared against Illumina-corrected reference genomes. In this small evaluation of 13 isolates we found that nanopore long read-only R10.4.1/kit 14 assemblies with updated basecallers trained using bacterial methylated DNA produce accurate assemblies with ≥40x depth, sufficient to be cost-effective compared with hybrid ONT/Illumina sequencing in our setting

Functional assessment of the NMDA receptor variant GluN2A (R586K)

Background: The N-methyl-D-aspartate receptor (NMDAR) is an ionotropic glutamate receptor that has important roles in synaptogenesis, synaptic transmission, and synaptic plasticity. Recently, a large number of rare genetic variants have been found in NMDAR subunits in people with neurodevelopmental disorders, and also in healthy individuals. One such is the GluN2AR586K variant (GRIN2AG1757A), found in a person with intellectual disability. Identifying the functional consequences, if any, of such variants allows their potential contribution to pathogenesis to be assessed. Here, we assessed the effect of the GluN2AR586K variant on NMDAR pore properties. Methods: We expressed recombinant NMDARs with and without the GluN2AR586K variant in Xenopus laevis oocytes and in primary cultured mouse neurons, and made electrophysiological recordings assessing Mg2+ block, single-channel conductance, mean open time and current density. Results: The GluN2AR586K variant was not found to influence any of the properties assessed. Conclusions: Our findings suggest it is unlikely that the GluN2AR586K variant contributes to the pathogenesis of neurodevelopmental disorder

Delayed prescribing of antibiotics for acute respiratory infections by GP registrars: a qualitative study

Background: Antibiotic prescribing for acute self-limiting respiratory tract infections (ARTIs) in Australia is higher than international benchmarks. Antibiotics have little or no efficacy in these conditions, and unnecessary use contributes to antibiotic resistance. Delayed prescribing has been shown to reduce antibiotic use. GP registrars are at a career-stage when long-term prescribing patterns are being established. Aim: To explore experiences, perceptions and attitudes of GP registrars and supervisors to delayed antibiotic prescribing for ARTIs. Design and setting: A qualitative study of Australian GP registrars and supervisors using a thematic analysis approach. Method: GP registrars and supervisors were recruited across three Australian states/territories, using maximum variation sampling. Telephone interviews explored participants’ experience and perceptions of delayed prescribing of antibiotics in ARTIs. Data collection and analysis were concurrent and iterative. Results: A total of 12 registrars and 10 supervisors were interviewed. Key themes included the use of delayed prescribing as a safety-net in cases of diagnostic uncertainty or when clinical review was logistically difficult. Delayed prescribing was viewed as a method of educating and empowering patients, and building trust and the doctor–patient relationship. Conversely, it was also seen as a loss of control over management decisions. Supervisors, more so than registrars, appreciated the psychosocial complexity of ARTI consultations and the importance of delayed antibiotic prescribing in this context. Conclusion: Better awareness and understanding by GP registrars of the evidence for delayed antibiotic prescription may be a means of reducing antibiotic prescribing. Understanding both registrar and supervisor usage, uncertainties and attitudes should inform educational approaches on this topic

Identification of novel small molecule inhibitors of adenovirus gene transfer using a high throughput screening approach

Due to many favourable attributes adenoviruses (Ads) are the most extensively used vectors for clinical gene therapy applications. However, following intravascular administration, the safety and efficacy of Ad vectors are hampered by the strong hepatic tropism and induction of a potent immune response. Such effects are determined by a range of complex interactions including those with neutralising antibodies, blood cells and factors, as well as binding to native cellular receptors (coxsackie adenovirus receptor (CAR), integrins). Once in the bloodstream, coagulation factor X (FX) has a pivotal role in determining Ad liver transduction and viral immune recognition. Due to difficulties in generating a vector devoid of multiple receptor binding motifs, we hypothesised that a small molecule inhibitor would be of value. Here, a pharmacological approach was implemented to block adenovirus transduction pathways. We developed a high throughput screening (HTS) platform to identify the small molecule inhibitors of FX-mediated Ad5 gene transfer. Using an in vitro fluorescence and cell-based HTS, we evaluated 10,240 small molecules. Following sequential rounds of screening, three compounds, T5424837, T5550585 and T5660138 were identified that ablated FX-mediated Ad5 transduction with low micromolar potency. The candidate molecules possessed common structural features and formed part of the one pharmacophore model. Focused, mini-libraries were generated with structurally related molecules and in vitro screening revealed novel hits with similar or improved efficacy. The compounds did not interfere with Ad5:FX engagement but acted at a subsequent step by blocking efficient intracellular transport of the virus. In vivo, T5660138 and its closely related analogue T5660136 significantly reduced Ad5 liver transgene expression at 48 h post-intravenous administration of a high viral dose (1 × 10<sup>11</sup> vp/mouse). Therefore, this study identifies novel and potent small molecule inhibitors of the Ad5 transduction which may have applications in the Ad gene therapy setting

LGBTQ+ Health Research Guides: A Cross-institutional Pilot Study of Usage Patterns

Objectives: Multiple authors have recommended that health sciences libraries use research guides to promote LGBTQ+ health information, connect with their users and the community, and improve health equity. However, little is known about LGBTQ+ health guide usage patterns and whether such guides really meet the information needs of their users. Based on usage patterns from LGBTQ+ health research guides, we assessed the types of LGBTQ+ health information of greatest interest to health sciences library users and how, if appropriate, these guides might be revised to be more relevant to user needs. Methods: The data for LGBTQ+ health research guides of five health sciences libraries (three in the United States and two in Canada) were studied. Usage data were retrieved for a three year period (July 2018-June 2021). Two separate factors were chosen for analysis: monthly guide usage over time and the individual types of resources used. Monthly usage was studied by generating line graphs in Excel with trendlines to calculate overall guide usage trends. To determine the most sought-after types of resources by users, clicks for individual resources were categorized by type and focus using open coding in Google Sheets. Results: Overall guide usage was mixed, with some libraries’ guides trending upward over time and others downward. Analysis of the resource links showed that links to local and community health resources were among the most heavily clicked (64.11% of clicks), as were resources designed to help patients find healthcare providers and services (53.23%). Links to library-owned resources, such as books, journals, and databases, were generally clicked less (2.44%), as were links aimed at healthcare professionals (11.36%). Conclusions: The usage statistics for the guides were relatively low. However, the size of the LGBTQ+ community is relatively low compared to the general population and therefore LGBTQ+ health can be considered a category of minority health. We argue that the importance of providing quality LGBTQ+ health information outweighs any concerns of large-scale usage, and that providing such guides promotes health equity. The higher usage numbers for local resources supports the idea that guides are most useful when they link users to services and providers in their own communities. This suggests a best practice for librarians to focus on local resources and collaborations, and on consumer health resources, when creating and editing these guides
