Abstract
Purpose
To determine the full-field electroretinogram (ffERG) parameters, including the light-adapted (LA) 3 ERG and the photopic negative response (PhNR), in 6- to 12-year-old children.

Methods
ffERG data were obtained from 214 eyes of 214 healthy subjects. The amplitudes and peak time of the ffERG responses were obtained from children divided into 6- to 8-year-old and 9- to 12-year-old groups. Using a skin electrode, electrical signals were measured in response to white stimulating light and white background light (LA 3 ERG). A blue background light and red flashes were then used to elicit the PhNR.

Results
The a-wave amplitude ranged from 0.40 to 9.20 μV, the b-wave ranged from 4.70 to 30.80 μV, and the PhNR ranged from 1.30 to 39.90 μV. The b-wave peak time (33.20 ms) of 6- to 8-year-old groups was slightly shorter than that of the 9- to 12-year-old groups (33.60 ms, P = 0.01), but no differences in amplitudes or in peak time of other components. There were significant correlations between the amplitudes (a-wave and b-wave: r = 0.43, p < 0.001; a-wave and PhNR: r = 0.25, p < 0.001; b-wave and PhNR: r = 0.45, p < 0.001). There was a moderate correlation between the a-wave and b-wave peak time (r = 0.31, P < 0.001).

Conclusions
We determined the largest dataset of the LA 3 ERG and PhNR parameters in a population of healthy children, aged 6–12 years, which may provide a useful reference value when evaluating children with potential retinal defects.
Clustering eye-movement data uncovers students’ strategies for coordinating equations and diagrams of vector fields
Authors: Hahn Larissa , Klein Pascal 
Published: August 2023

AbstractIn mathematics education, students are repeatedly confronted with the tasks of interpreting and relating different representations. In particular, switching between equations and diagrams plays a major role in learning mathematical procedures and solving mathematical problems. In this article, we investigate a rather unexplored topic with precisely such requirements—that is, vector fields. In our study, we first presented a series of multiple-choice tasks to 147 introductory university students at the beginning of their studies and recorded students’ eye movements while they matched vector field diagrams and equations. Thereafter, students had to solve a similar coordination task on paper and justify their reasoning. Two cluster analyses were performed including (i) transition and fixation data on diagrams and options (Model 1), and (ii) additionally the number of horizontal and vertical saccades on the diagram (Model 2). In both models, two clusters emerge—with Model 1 distinguishing behaviors related to representational mapping and Model 2 additionally differentiating students according to representation-specific demands. Model 2 leads to a better distinction between the groups in terms of different performance indicators (test score, response confidence, and spatial ability) which also transfers to another task format. We conclude that vertical and horizontal saccades reflect executive actions of perception when approaching vector field coordination tasks. Thus, we recommend targeted interventions for mathematics lessons; these lessons must focus on a visual handling of the vector field diagram. Further, we infer that students’ difficulties can be attributed to covariational reasoning, thereby indicating the need for further investigations. From a methodological perspective, we reflect on the triangulation of eye-tracking and verbal data in (multiple-choice) assessment scenarios.
Rating and perceived helpfulness in a bipartite network of online product reviews
Authors: Campos Pedro , Pinto Eva , Torres Ana 
Published: August 2023

AbstractIn many e-commerce platforms user communities share product information in the form of reviews and ratings to help other consumers to make their choices. This study develops a new theoretical framework generating a bipartite network of products sold by Amazon.com in the category “musical instruments”, by linking products through the reviews. We analyze product rating and perceived helpfulness of online customer reviews and the relationship between the centrality of reviews, product rating and the helpfulness of reviews using Clustering, regression trees, and random forests algorithms to, respectively, classify and find patterns in 2214 reviews. Results demonstrate: (1) that a high number of reviews do not imply a high product rating; (2) when reviews are helpful for consumer decision-making we observe an increase on the number of reviews; (3) a clear positive relationship between product rating and helpfulness of the reviews; and (4) a weak relationship between the centrality measures (betweenness and eigenvector) giving the importance of the product in the network, and the quality measures (product rating and helpfulness of reviews) regarding musical instruments. These results suggest that products may be central to the network, although with low ratings and with reviews providing little helpfulness to consumers. The findings in this study provide several important contributions for e-commerce businesses’ improvement of the review service management to support customers’ experiences and online customers’ decision-making.

Published: August 2023

AbstractSeasonal movements between the summer and winter areas are a widespread phenomenon in bats So far, most information on the migration ecology of bats has been obtained by studies in terrestrial habitats, whereas scientific knowledge on migration over sea is scarce. We performed continuous ultrasonic acoustic monitoring at 13 locations in the southern North Sea during four consecutive years (2017–2020) and analysed the spatiotemporal occurrence of Nathusius’ pipistrellePipistrellus nathusiiduring autumn migration in relation to weather parameters and lunar phase. Our analysis showed that the main autumn migration of Nathusius’ pipistrelle at the southern North Sea occurs from mid-August until late October and most bats within the study area occur off the Noord Holland coast. North Sea crossings frequently last longer than one night; the day is spent roosting at an offshore structure. The strongest migration occurs during nights with tailwinds from the east-northeast, but bats are also recorded offshore with low to moderate headwinds or crosswinds. Bat presence decreased between the full moon and the last quarter and increased just before the new moon. Finally, our observations show that the occurrence of bats at sea was reduced in 2020 in comparison to the previous years. The results of this study show clear spatiotemporal patterns of migratory bat occurrence at the southern North Sea. The spatial distribution can be used in spatial planning of future offshore wind farms, whereas the temporal occurrence and environmental factors that shape offshore migration can be used to develop mitigation measures to reduce the number of bat fatalities.
Discourses on Non-Heteronormative Masculinities and Intimate Partner Violence: a Russian Media Case Study
Authors: Andreevskikh Olga 
Published: August 2023

Abstract
Purpose
The current paper is devoted to the analysis of the mediation of non-heteronormative masculinities within discourses on intimate partner violence (IPV) and domestic violence and abuse (DVA) in contemporary Russian media.

Methods
The article presents a discourse analysis of five samples of media texts devoted to IPV and/or DVA among LGBTQ people. The media texts were sampled through a keyword search completed on the websites of two openly pro-LGBTQ media outlets (news and entertainment portals Meduza and Takie Dela) and two media outlets catered for predominantly LGBTQ audiences (the news and entertainment portal Parni PLUS and the website of the NGO SPID-Tsentr).

Results
The interpretative qualitative analysis of the sampled texts demonstrated that the IPV/DVA survivors’ confessional narratives are framed within wider discourses on non-heteronormative masculinities, which are represented both as transgressing concepts of hegemonic masculinity and as challenging stereotypes about non-heteronormative masculinities.

Conclusions
The outcome of the analysis presented in the paper is that there is evidence of the emergence of new media discourses on IPV and DVA among LGBTQ communities. Drawing on feminist discourses on IPV and DVA in heterosexual relationships and using media strategies of LGBTQ coming-out confessional narratives, the sampled media data reveals an ongoing search for a new language of discussing the relatively new societal problem. Further research into mediation of non-heteronormative male survivors of IPV and DVA promises insightful findings concerning the evolution of discourses on non-heteronormative masculinities in contemporary Russian media.
Policing Technology-Facilitated Domestic Abuse (TFDA): Views of Service Providers in Australia and the United Kingdom
Authors: Douglas Heather , Tanczer Leonie , McLachlan Freya , Harris Bridget 
Published: August 2023

Abstract

Purpose
Technology-facilitated domestic abuse (TFDA) is a prevalent form of domestic abuse. While police are recognized as critical first responders to intimate partner violence, there is limited research about what the challenges to policing TFDA are perceived to be and how they might be addressed. This article speaks to this issue.

Methods
Between April 2020 and June 2022, n = 196 Australian and n = 256 United Kingdom representatives of services engaged with domestic abuse victim-survivors participated in an online survey about TFDA. Survey components asked respondents to report on challenges to policing TFDA. The authors analyzed these comments.

Results
Key themes identified from the survey responses regarding challenges to policing TFDA include that participants held perceptions that (a) police do not recognize TFDA as an aspect of coercive control and thus do not recognize its seriousness, (b) police receive inadequate training about TFDA, (c) police have insufficient time and personnel to tackle TFDA and (d) evidence collection is an obstacle to policing TFDA.

Conclusions
The study points to a need to address the perceived concerns associated with policing TFDA to effectively respond to domestic abuse in the digital age and ensure domestic abuse perpetrators who misuse emerging technologies are held accountable.
Dyslipidemia initiates keratinocytes proliferation through upregulation of lncRNA NEAT in psoriasis patients
Authors: Mostafa Abeer , Sabry Dina , Aboraia Nesreen , Fawzy Ahmed , Abou-Elalla Amany A. 
Published: August 2023

Abstract
Background
Psoriasis is a chronic inflammatory immune-mediated and hyper proliferative skin disorder that has underlying genetic factors. Psoriasis can result from interaction of cytokines between keratinocytes and T-lymphocytes. NEAT is a lncRNA involved in immune modulation and has been previously studied in cancers. This study aims to clarify the unprecedented role of NEAT in psoriasis pathogenesis.

Methods
The study was conducted on 50 healthy control subjects and 50 psoriasis patients. Blood samples from all participants were collected for analysis of their lipid profile. qRT-PCR was done for lncRNA NEAT, TNF-α, VEGF genes expression. The levels of ROS and caspase-3 were estimated by ELISA. ROC analysis was done to detect the diagnostic value of lncRNA NEAT gene expression.

Results
Dyslipidemia is more prevalent among psoriasis patients. A significant up regulation in lncRNA NEAT, TNF-α, VEGF genes expression (p value˂0.001) in psoriasis patients in addition to significant increase in ROS and caspase-3 levels (p value˂0.001) in compare to controls. Additionally, a positive significant correlation between TNF-α, ROS, NEAT, caspase-3 and dyslipidemia. NEAT had an area under the curve (AUC) of 0.931 (95% CI 0.844–0.978, p < 0.001).

Conclusion
Dyslipidemia is an initiating signal in psoriasis pathogenesis that creates a state of chronic inflammation and oxidative stress. This state induces keratinocytes proliferation and release of NEAT with subsequent caspase-3 activation to counteract the proliferating cells. NEAT could be considered as a good diagnostic biomarker for psoriasis.

Detection of central serous retinopathy using deep learning through retinal images
Authors: Hassan Syed Ale , Akbar Shahzad , Khan Habib Ullah 
Published: August 2023

AbstractThe human eye is responsible for the visual reorganization of objects in the environment. The eye is divided into different layers and front/back areas; however, the most important part is the retina, responsible for capturing light and generating electrical impulses for further processing in the brain. Several manual and automated methods have been proposed to detect retinal diseases, though these techniques are time-consuming, inefficient, and unpleasant for patients. This research proposes a deep learning-based CSR detection employing two imaging techniques: OCT and fundus photography. These input images are manually augmented before classification, followed by training of DarkNet and DenseNet networks through both datasets. Moreover, pre-trained DarkNet and DenseNet classifiers are modified according to the need. Finally, the performance of both networks on their datasets is compared using evaluation parameters. After several experiments, the best accuracy of 99.78%, the sensitivity of 99.6%, specificity of 100%, and the F1 score of 99.52% were achieved through OCT images using the DenseNet network. The experimental results demonstrate that the proposed model is effective and efficient for CSR detection using the OCT dataset and suitable for deployment in clinical applications.
Psychometric properties of health-related quality of life instruments used in survivors of critical illness: a systematic review
Authors: De Silva Sheraya , Chan Nicholas , Esposito Katherine , Higgins Alisa M. , Hodgson Carol L. 
Published: August 2023

Abstract
Background and objectives
Health-related quality of life (HRQoL) is a patient-reported measure of health status. However, research on the psychometric properties of HRQoL instruments used post-critical care is less common. We conducted a systematic review assessing the psychometric properties of HRQoL instruments used in adult survivors following critical illness.

Methods
Three databases were systematically searched between 1990 and June 2022. Screening articles for eligibility, we selected either development studies for new tools or studies that evaluated psychometric properties, and whose target population represented adult survivors following critical illness. Methodological quality was assessed using the COnsensus-Based Standards for the selection of health Measurement INstruments (COSMIN) checklist. The results of each psychometric property were then assessed for criteria of good psychometric properties (sufficient, insufficient or indeterminate) and qualitatively summarised. Finally, we graded the quality of the evidence using a modified GRADE approach.

Results
We retrieved 13 eligible studies from 2,983 records identifying 10 HRQoL instruments used post-critical illness. While high-quality evidence for the considered PROMs was limited primarily due to risk of bias, seven instruments demonstrated sufficient levels of reliability, four instruments presented sufficient hypothesis testing, and two instruments showed sufficient responsiveness. Except the Short Form-36, evidence for psychometric properties of other individual measures was limited to a few studies.

Conclusion
There was limited evidence demonstrated for the psychometric properties of the included PROMs evaluating HRQoL. Further research is warranted to evaluate the psychometric properties of HRQoL measures, strengthening the evidence for administering these instruments in survivors following critical illness.
Small-scale fishing has affected abundance and size distributions of deepwater snappers and groupers in the MesoAmerican region

Published: August 2023

AbstractDeepwater fisheries in the Caribbean Sea are poorly studied and mostly unmanaged, despite their importance to local economies and food security. In the MesoAmerican region, deepwater fisheries are nearshore and easily accessible in many locations by small vessels, but historical and contemporary fishing effort varies by country. We used standardized fishery-independent methods, including vertical longlines and baited remote underwater video (BRUV) to assess the relative abundance and distribution of deepwater (100–550 m) snappers and groupers in Belize and Honduras. Fishery-dependent samples were used to supplement spatial distribution and body length data. Gathered data revealed that Belize, with a smaller fishing population and shorter history of deepwater fishing, had overall higher abundance of groupers and snappers and that fish were significantly larger than those in Honduras, which has a well-established and larger deepwater fishery. Water temperature was found to influence the abundance and occurrence of deepwater snappers more than depth. Deepwater snappers were widely-distributed throughout available habitat in both countries, but groupers were more patchy, and rarely encountered in the more heavily fished areas off Honduras. Our results suggest that a precautionary approach to fisheries management and targeted biological research of these stocks is required, which is particularly relevant for Belize, where climate change and overfishing mitigation measures are focused on an expansion of the deepwater fishery.
Artificial intelligence and firm growth — catch-up processes of SMEs through integrating AI into their knowledge bases
Authors: Kopka Alexander , Fornahl Dirk 
Published: August 2023

AbstractArtificial intelligence (AI) is seen as a key technology for future economic growth. It is labelled as a general-purpose technology, as well as an invention of a method for inventing. Thus, AI is perceived to generate technological opportunities and through these, innovations, and productivity growth. The leapfrogging hypothesis suggests that latecomer firms can use these opportunities to catch up. The aim of this paper is to provide insight into this catch-up process of latecomer firms through integrating AI into their knowledge portfolio and thereby creating new technological trajectories. The moderating effect of firm size is also analysed. Combining firm-level data with patent data, a regression at the firm level is conducted. Evidence is found that smaller firms experience productivity growth from AI when operating at the productivity frontier, indicating the opposite of the leapfrogging hypothesis. However, there is evidence for the positive impact of AI on firm innovation, which is higher for latecomer firms that are larger in size. In general, we find a diverging pattern of the influence of AI on productivity and innovation growth, indicating the need for a finer grained analysis that takes indirect effects - that also could explain the observed productivity paradox - into account.
Non-dynamism and temporal disturbances
Authors: Baron Sam , Latham Andrew J. , Varga Somogy 
Published: August 2023

AbstractPhilosophical accounts denying that temporal passage is an objective feature of reality face an explanatory challenge with respect to why it appears to us as though time passes. Recently, two solutions have surfaced. Cognitive illusionism claims that people experience the passage of time due to their belief that time passes. Cognitive error theory claims that we do not experience the passage of time, but hold the belief that we do, which we have acquired through making an inference from the prior belief that time passes. These approaches suppose that belief and passage experience are explanatorily connected, and they depend on the claims that people who experience the passage of time or at least believe that they do also believe that time passes. To test these claims, we probed the beliefs of populations of individuals with depression and schizotypy, thus conditions that are strongly associated with alterations in temporal phenomenology. Depression was assessed with the Beck Depression Inventory (BDI) and schizotypy with the short Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE). While cognitive illusionism and inferentialist cognitive error theory would predict a strong association between BDI and O-LIFE scores and beliefs about time passage, our study found no such association. The experience of passage does not seem to be explanatorily connected to beliefs about the passage of time.

Abstract
Purpose
Oral anticoagulants effectively prevent stroke/systemic embolism among patients with non-valvular atrial fibrillation but remain under-prescribed. This study evaluated temporal trends in oral anticoagulant use, the incidence of stroke/systemic embolism and major bleeding, and economic outcomes among elderly patients with non-valvular atrial fibrillation and CHA2DS2–VASc scores ≥ 2.

Methods
Retrospective analyses were conducted on Medicare claims data from January 1, 2012 through December 31, 2017. Non-valvular atrial fibrillation patients aged ≥ 65 years with CHA2DS2–VASc scores ≥ 2 were stratified by calendar year (2013–2016) of care to create calendar-year cohorts. Patient characteristics were evaluated across all cohorts during the baseline period (12 months before diagnosis). Treatment patterns and clinical and economic outcomes were evaluated during the follow-up period (from diagnosis through 12 months).

Results
Baseline patient characteristics remained generally similar between 2013 and 2016. Although lack of oral anticoagulant prescriptions among eligible patients remained relatively high, utilization did increase progressively (53–58%). Among treated patients, there was a progressive decrease in warfarin use (79–52%) and a progressive increase in overall direct oral anticoagulant use (21–48%). There were progressive decreases in the incidence of stroke/systemic embolism 1.9–1.4 events per 100 person years) and major bleeding (4.6–3.3 events per 100 person years) as well as all-cause costs between 2013 and 2016.

Conclusions
The proportions of patients with non-valvular atrial fibrillation who were not prescribed an oral anticoagulant decreased but remained high. We observed an increase in direct oral anticoagulant use that coincided with decreased incidence of clinical outcomes as well as decreasing total healthcare costs.
