Authors: Ghosh Dastidar Kanishka , Jurgovsky Johannes , Siblini Wissam , Granitzer Michael 
Published: February 2022

AbstractThe state-of-the-art feature-engineering method for fraud classification of electronic payments uses manually engineered feature aggregates, i.e., descriptive statistics of the transaction history. However, this approach has limitations, primarily that of being dependent on expensive human expert knowledge. There have been attempts to replace manual aggregation through automatic feature extraction approaches. They, however, do not consider the specific structure of the manual aggregates. In this paper, we define the novel Neural Aggregate Generator (NAG), a neural network-based feature extraction module that learns feature aggregates end-to-end on the fraud classification task. In contrast to other automatic feature extraction approaches, the network architecture of the NAG closely mimics the structure of feature aggregates. Furthermore, the NAG extends learnable aggregates over traditional ones through soft feature value matching and relative weighting of the importance of different feature constraints. We provide a proof to show the modeling capabilities of the NAG. We compare the performance of the NAG to the state-of-the-art approaches on a real-world dataset with millions of transactions. More precisely, we show that features generated with the NAG lead to improved results over manual aggregates for fraud classification, thus demonstrating its viability to replace them. Moreover, we compare the NAG to other end-to-end approaches such as the LSTM or a generic CNN. Here we also observe improved results. We perform a robust evaluation of the NAG through a parameter budget study, an analysis of the impact of different sequence lengths and also the predictions across days. Unlike the LSTM or the CNN, our approach also provides further interpretability through the inspection of its parameters.

Published: February 2022

AbstractPhotodocumentation is a subset of visible light imaging and is an important growing segment of enterprise imaging. Medical videography is another subset of visible light imaging that shares many of the challenges of photodocumentation. Medical photographs are used to document clinical conditions, support diagnosis, guide, and document procedures and to enable collaboration among colleagues. They also play a significant role in patient engagement and are a mechanism for patients to share information with their provider without the need for a clinical office visit. The content of medical photographs raises issues for acquisition, management, storage, and access. Medical photographs may contain protected health information, and these images benefit from the standardized, secure processes inherent in any enterprise imaging program. The ability to securely acquire images on mobile, and sometimes personally owned devices, is a necessity. In addition to containing protected health information, photograph content can be sensitive or gruesome or the images may be used for forensic purposes. These types of images require additional protections. Access to these images should be role-based and auditable. To properly identify photographs and to convey information about their acquisition parameters new metadata requirements and mechanisms for its association with the imaging files are evolving. Institutional policies need to be developed to define the organization’s requirements for medical photography, including consent processes. Existing policies such as those defining the designated record set and legal health record should address the management of medical photography.

Abstract
Background
The Ubiquitin-conjugating enzyme 2C (UBE2C) is essential for the ubiquitin–proteasome system and is involved in cancer cell migration and apoptosis. This study aimed to determine the prognostic value of UBE2C in invasive breast cancer (BC).

Methods
UBE2C was evaluated using the Molecular Taxonomy of Breast Cancer International Consortium (n = 1980), The Cancer Genome Atlas (n = 854) and Kaplan–Meier Plotter (n = 3951) cohorts. UBE2C protein expression was assessed using immunohistochemistry in the BC cohort (n = 619). The correlation between UBE2C, clinicopathological parameters and patient outcome was assessed.

Results
High UBE2C mRNA and protein expressions were correlated with features of poor prognosis, including high tumour grade, large size, the presence of lymphovascular invasion, hormone receptor negativity and HER2 positivity. High UBE2C mRNA expression showed a negative association with E-cadherin, and a positive association with adhesion molecule N-cadherin, matrix metalloproteinases and cyclin-related genes. There was a positive correlation between high UBE2C protein expression and cell cycle-associated biomarkers, p53, Ki67, EGFR and PI3K. High UBE2C protein expression was an independent predictor of poor outcome (p = 0.011, HR = 1.45, 95% CI; 1.10–1.93).

Conclusion
This study indicates that UBE2C is an independent prognostic biomarker in BC. These results warrant further functional validation for UBE2C as a potential therapeutic target in BC.
Are Algorithmic Decisions Legitimate? The Effect of Process and Outcomes on Perceptions of Legitimacy of AI Decisions
Authors: Martin Kirsten , Waldman Ari 
Published: February 2022

AbstractFirms use algorithms to make important business decisions. To date, the algorithmic accountability literature has elided a fundamentally empirical question important to business ethics and management: Under what circumstances, if any, are algorithmic decision-making systems considered legitimate? The present study begins to answer this question. Using factorial vignette survey methodology, we explore the impact of decision importance, governance, outcomes, and data inputs on perceptions of the legitimacy of algorithmic decisions made by firms. We find that many of the procedural governance mechanisms in practice today, such as notices and impact statements, do not lead to algorithmic decisions being perceived as more legitimate in general, and, consistent with legitimacy theory, that algorithmic decisions with good outcomes are perceived as more legitimate than bad outcomes. Yet, robust governance, such as offering an appeal process, can create a legitimacy dividend for decisions with bad outcomes. However, when arbitrary or morally dubious factors are used to make decisions, most legitimacy dividends are erased. In other words, companies cannot overcome the legitimacy penalty of using arbitrary or morally dubious factors, such as race or the day of the week, with a good outcome or an appeal process for individuals. These findings add new perspectives to both the literature on legitimacy and policy discussions on algorithmic decision-making in firms.
Key factors in digital literacy in learning and education: a systematic literature review using text mining
Authors: Audrin Catherine , Audrin Bertrand 
Published: February 2022

AbstractThis research aims at providing an overview of the research field of digital literacy into learning and education. Using text mining, it reviews 1037 research articles published on the topic between 2000 and 2020. This review reveals that there is a plurality of terms associated with digital literacy. Moreover, our research identifies six key factors that define the literature, which are information literacy, developing digital literacy, digital learning, ICT, social media, and twenty-first century digital skills. These factors can be grouped into three main streams, which are 1) digital literacy, 2) digital learning and 3) twenty-first century digital skills. These three streams are supported by informational and technological foundations. These results provide research avenues and offer a framework for digital literacy in education.

Published: February 2022

AbstractResearch has shown that students differ in their abilities to evaluate the credibility of online texts, and, in general, many perform poorly on online evaluation tasks. This study extended current knowledge by examining students’ abilities to justify the credibility of online texts from different perspectives, thus providing a more nuanced understanding of students’ credibility evaluation ability. We examined how upper secondary school students (N = 73; aged 16 to 17) evaluated author expertise, author intention, the publication venue, and the quality of evidence when reading four texts about the effects of sugar consumption in a web-based environment. Additionally, we examined how students’ prior topic knowledge, Internet-specific justification beliefs, and time on task were associated with their credibility justifications. Students evaluated author expertise, author intention, the venue, and the quality of evidence for each text on a six-point scale and provided written justifications for their evaluations. While students’ credibility evaluations were quite accurate, their credibility justifications lacked sophistication. Inter-individual differences were considerable, however. Regression analysis revealed that time on task was a statistically significant unique predictor of students’ credibility justifications. Instructional implications are discussed.
Lacan’s Dialectics of Knowledge Production: The Four Discourses as a Detour to Hegel
Authors: Zwart Hub 
Published: February 2022

AbstractIn Seminar XVII, entitled The reverse side of psychoanalysis , Jacques Lacan
presents his famous theorem of the four discourses. In this rereading I propose to
demonstrate that Lacan’s theorem entails a transferable dialectical method for studying
processes of knowledge production, enabling contemporary scholars to develop a
diagnostic of the present, notably scholars interested in issues such as the vicissitudes
of knowledge production under capitalism, the crisis of the university and the
proliferation of electronic gadgets. In short, I will argue that Lacan’s theorem of the four
discourses entails a dialectical diagnostic of technoscientific knowledge during late
capitalism. First, the four discourses will be briefly outlined, emphasising the extent to
which they entail, albeit in an ambivalent manner, a return or detour to the logic of
Hegel. Subsequently, each discourse will be presented in more detail, emphasising
how they allow us to come to terms with the current status of technoscientific
knowledge. Special attention will be given to the political backdrop of the seminar: the
crisis of the university. Finally, I will discuss the historical dimension, outlining both the
predecessor of the four discourses and their current predicament under neoliberal/capitalist conditions.
The supporting hyperplane optimization toolkit for convex MINLP
Authors: Lundell Andreas , Kronqvist Jan , Westerlund Tapio 
Published: February 2022

AbstractIn this paper, an open-source solver for mixed-integer nonlinear programming (MINLP) problems is presented. The Supporting Hyperplane Optimization Toolkit (SHOT) combines a dual strategy based on polyhedral outer approximations (POA) with primal heuristics. The POA is achieved by expressing the nonlinear feasible set of the MINLP problem with linearizations obtained with the extended supporting hyperplane (ESH) and extended cutting plane (ECP) algorithms. The dual strategy can be tightly integrated with the mixed-integer programming (MIP) subsolver in a so-called single-tree manner, i.e., only a single MIP optimization problem is solved, where the polyhedral linearizations are added as lazy constraints through callbacks in the MIP solver. This enables the MIP solver to reuse the branching tree in each iteration, in contrast to most other POA-based methods. SHOT is available as a COIN-OR open-source project, and it utilizes a flexible task-based structure making it easy to extend and modify. It is currently available in GAMS, and can be utilized in AMPL, Pyomo and JuMP as well through its ASL interface. The main functionality and solution strategies implemented in SHOT are described in this paper, and their impact on the performance are illustrated through numerical benchmarks on 406 convex MINLP problems from the MINLPLib problem library. Many of the features introduced in SHOT can be utilized in other POA-based solvers as well. To show the overall effectiveness of SHOT, it is also compared to other state-of-the-art solvers on the same benchmark set.
Colorectal Cancer Screening in Castilla La Mancha, Spain: The Influence of Social, Economic, Demographic and Geographic Factors
Authors: González Laura Valiente , Sotos Francisco Escribano , de Miguel Ibáñez Ricardo 
Published: February 2022

AbstractColorectal cancer (CRC) is a health problem with a significant social impact, accounting for 700,000 deaths a year globally. CRC survival rates are increasing as a result of early detection and improvements in society and labor conditions. Differences in CRC have been found depending on place of residence (urban or rural), socioeconomic situation and unemployment, although studies in this regard are limited. The aims of the present study were to determine whether differences exist in diagnostic delay according to place of residence, to analyze the association between socioeconomic level and colonoscopy results and to evaluate CRC risk according to place of residence, income level and unemployment. Retrospective, descriptive and observational study based on colonoscopies performed between May 2015 and November 2018, analyzing relationships between colonoscopy findings of a population screening program and various socioeconomic and demographic variables included in the study (sex, age, place of residence, average annual income, unemployment rate, etc.), and determining any association between such factors and related increases in adenocarcinoma risk. A total of 1422 patients were included in the study. The difference in participation according to sex was greater in rural population (63,4% men/36,6% women in rural areas, 58% men/42% women in urban areas). The mean delayed diagnosis was 59,26 days in both groups. Adenocarcinoma risk was 1.216 times higher in rural population. High-grade dysplasic lesions and adenocarcinoma were more common in municipalities with income < 9000€. However, advanced stage adenocarcinoma was higher in municipalities with income > 9000€. Adenocarcinoma risk was 1,088 times higher in municipalities with an unemployment rate of > 10%. Living in rural areas is not a barrier to access to health care, with no disadvantages identified regarding diagnosis and treatment, thanks to public health policies and the large number of small municipalities near the referral hospital in Cuenca.
A parallel-elastic actuation approach for wide bandwidth fingertip haptic devices
Authors: Leonardis Daniele , Santamato Giancarlo , Gabardi Massimiliano , Solazzi Massimiliano , Frisoli Antonio 
Published: February 2022

AbstractWearable haptic devices are used to render sense of touch in different virtual reality, simulated or teleoperated environments. Design of these devices has to comply with dimensional constraints imposed by ergonomics and usability, introducing compromises between size of the actuators and features of the rendered haptic stimuli, such as peak forces and bandwidth. We propose a new design approach for wearable haptic devices resembling the micro-macro actuation concept: it is based on two distinct actuators with different mechanical reduction, coupled by an elastic element. We show this better matches the output range of the actuators to features of the signals used in typical haptic rendering. We investigated the approach through an analytical model, a numerical model, and physical experiments conducted after design and development of a working prototype. The theoretical and simulated models allow to better understand dynamic interaction of the system parts, and to define design guidelines for the development of the real device. The adopted design solutions were implemented and evaluated in the prototype of a highly wearable fingertip device. Final experimental results show how the implementation of the proposed method is capable of an effective haptic rendering, that better matches the desired frequency response.
The protected antimicrobial process in a University Teaching Hospital: a qualitative interview study exploring the knowledge, attitudes, and experiences of healthcare professionals
Authors: Burton E. , O’Driscoll M. , Fleming A. 
Published: February 2022

AbstractBackground The protected or restricted supply of certain antimicrobials such as linezolid, caspofungin, aztreonam, in the acute hospital setting is an important element of Antimicrobial Stewardship (AMS) programmes to address the growing problem of antimicrobial resistance. This process involves submitting an application for use to be reviewed typically by a Consultant Microbiologist, Infectious Disease Consultant or Antimicrobial Pharmacist. Aim To investigate healthcare professionals’ knowledge, experiences, and attitudes towards the protected/restricted antimicrobials process in order to identify possible methods of optimisation and improvement. Method Semi-structured interviews with stakeholders involved in the protected/restricted antimicrobial prescribing, dispensing and administration process were conducted in September–October 2019 in a 350-bed voluntary, general, acute hospital in Ireland. Interviews were analysed by the Framework method and mapped to the Theoretical Domains Framework (TDF). Results Interviews were conducted with 8 Doctors, 4 Pharmacists and 3 Nurses. TDF domains identified included: ‘Knowledge’; ‘Social/professional role and identity’; ‘Social influences’; ‘Memory, attention and decision processes’; ‘Beliefs about consequences’; ‘Environmental contexts and resources’. The relationship between prescribers and the AMS Team was reported as a facilitator of the process, whereas the inconsistency of the filing and versions of forms on the wards were seen as challenges. Conclusion The results of this study have shown that the existing protected/restricted antimicrobial process is a multi-disciplinary effort with barriers that require attention in order to make future improvements. Standardization of the form across all wards, an electronic version of the form, and structured education around AMS were suggested to optimize the process.
The effect of efficient professional development on the teaching of code-focused skills in beginner readers: exploring the impact of professional development intensity and coaching on student outcomes
Authors: Martínez Verónica , Castejón Luis , González-Pumariega Soledad 
Published: February 2022

AbstractProfessional development (PD) of teachers working with students in the first years of learning to read is a privileged way of preventing initial reading difficulties and its effects in the long and short term. This research studies the effects of PD in student reading performance, although the results are not conclusive with regard to which PD format is more adequate. The objective of this study is to determine which modality (face-to-face with a coach vs. without a coach) and intensity (number of contact hours) of PD are more efficient in achieving fluency improvement in student performance in the code-focussed skills in the first years of learning to read. Both pre-schoolers and their teachers took part in the study with a quasi-experimental pre-test post-test design. The experimental group (n = 71) was provided literacy instruction from teachers (n = 8) who received 40 h of face-to-face training with a coach and the control group (n = 29) was provided literacy instruction from teachers (n = 8) who received only 8 h of initial training (without coaching). The results showed significant intra-group improvements with a large reduction in students at risk for reading difficulties. No significant differences were obtained between groups in reading performance. This suggests greater efficiency in a lower intensity format of PD without a coach in the development of code-focussed skills. The study considers the need to adequately assess reading ability in the light of attitude and motivation of teachers as variables which influence the efficiency of PD.
Gastrointestinal helminth parasites of the threatened Australasian crested grebe (Podiceps cristatus australis, Gould 1844) in New Zealand, with descriptions of Baruscapillaria kamanae n. sp. (Nematoda: Trichuridae) and Cryptocotyle micromorpha n. sp. (Trematoda: Opisthorchiidae)

Published: February 2022

AbstractThe Australasian crested grebe Podiceps cristatus australis, Gould 1844 is restricted to Australia and New Zealand, where it is listed as Threatened and Nationally Vulnerable. For the first time in New Zealand, we report on the parasitic helminths infecting three individuals from Lake Wanaka, Otago, using morphological and molecular tools. Seven helminth species were found in the gastrointestinal tract: 2 nematodes (Contracaecum ovale and Baruscapillaria kamanaen. sp.), 4 trematodes (Australapatemon minor, Cryptocotyle micromorphan. sp., Tylodelphys darbyi and Neopetasiger neocomensis), and 1 cestode (Confluaria pseudofurcifera). Except for T. darbyi, all are new records for New Zealand. A change of orthography is proposed for Neopetasiger neocomensis and N. pseudoneocomensis. Cryptocotyle micromorphan. sp. (Opisthorchiidae) is distinguished from similar species by its small size, wholly extracaecal vitellaria and anteriorly looped uterus. Baruscapillaria kamanaen. sp. (Trichuridae) is distinguished from other freshwater species by a combination of vulva and spicule morphology. The helminth parasites found here are mostly the same as those from the grebe in the northern hemisphere, indicating that they have been carried with the host species in its spread to Australasia. However, the parasite fauna may be depauperate due to a diminishing reservoir of intermediate hosts in that geographical migration.
