Authors: Sayahi Masoumeh , Nikbina Maryam , Jahangirimehr Azam , Barati Barat
Published: November 2023

Background and objective

The COVID-19 pandemic impacted every single aspect of life. In addition to being a public health emergency, the COVID-19 outbreak impacted the mental health of individuals, especially pregnant women. This study aimed to examine the mental health status of pregnant women and also the effect of sociodemographic factors on their mental health status during COVID-19 in healthcare centers of Iran.

Methods

This cross-sectional, analytical-descriptive study was conducted among pregnant women referring to healthcare centers in Shoushtar, Iran, in 2021. Multistage cluster sampling was used to select participants. Data were collected using the General Health Questionnaire-28 (GHQ-28). Data were analyzed using SPSS software version 22. The Pearson correlation coefficient was used to examine the association between quantitative variables. A generalized linear model (GLM) was applied to estimate the effect of independent variables on the dependent variable (mental health).

Results

A total of 197 participants with a mean ± SD age of 27.85 ± 6.37 years took part in this study. The total mean score of mental health was estimated at 17.47±8.20. The highest mean ± SD score was, respectively, related to social dysfunction (6.63 ± 2.86), anxiety and insomnia (5.28 ± 3.53), and somatic symptoms (4.17 ± 3.27). Mental health disorder was significantly correlated with participants’ age (R = .223, P = .00), number of pregnancy (gravida) (R = .272, P = .00), number of births (para) (R = 0.272, P = .00), and number of abortions (R = .172, P = .015). About 80% of pregnant women did not reveal impaired mental health conditions or psychological distress, while 19.3% showed scores that indicate probable mental health conditions.

Conclusion

Social dysfunction was the most common mental health problem among pregnant women. It is necessary to pay more attention to the mental health status of pregnant women during a pandemic. Interventions such as practical strategies to promote social support and improve pregnant women’s mental health during pregnancy are highly important.

Objective

The present study aims to measure the prevalence of non-disabled frailty and its associated factors among Bangladeshi older adults.

Methods

This cross-sectional study was conducted during September and October 2021 among 1,045 Bangladeshi older adults (≥60 years). Telephone interviews, using a semi-structured questionnaire, were undertaken to collect data on participants’ characteristics and level of frailty. The non-disabled frailty was measured using the ‘Frail Non-Disabled (FiND)’ questionnaire. A multinomial logistic regression model assessed the factors associated with frailty among the participants.

Results

Around a quarter of the participants (24.8%) were frail. The multinomial regression analysis showed that older participants aged ≥80 years (RRR = 3.23, 95% CI: 1.41–7.37) were more likely to be frail compared to participants aged 60–69 years. Likewise, the participants living in a large family with ≥4 members (RRR = 1.39, 95% CI: 1.01–1.92) were more likely to be frail compared to those living in smaller families. Also, participants having memory or concentration problems (RRR = 1.56, 95% CI: 1.12–2.17) were more likely to be frail compared to those who were not suffering from these problems. Moreover, participants whose family members were non-responsive to their day-to-day assistance (RRR = 1.47, 95% CI: 1.06–2.03) were more likely to be frail compared to those whose family members were responsive. Furthermore, participants who were feeling lonely (RRR = 1.45, 95% CI: 1.07–1.98) were more likely to be frail than their counterparts who were not feeling lonely.

Conclusions

The findings of the present study suggest developing tailored interventions to address the burden of frailty among the older populations in Bangladesh. In particular, providing long-term care and health promotion activities can be of value in preventing frailty and reducing adverse health outcomes among this vulnerable population group.

Authors: Polato Rafaella Rabelo , Oliveira Cristino Carneiro , Miranda Yuri Augusto de Sousa , Cabral Leandro Ferracini , Malaguti Carla , José Anderson
Published: November 2023

Introduction

Several individuals with post-COVID-19 syndrome referred for pulmonary rehabilitation did not participate. This study aimed to explore individuals’ barriers to participating in posthospitalization COVID-19 rehabilitation.

Materials and methods

This was a qualitative, multicenter study performed using semistructured interviews. This study included 20 individuals hospitalized for COVID-19 who refused to participate in a pulmonary rehabilitation program at a university hospital.

Results

Individuals reported difficulties accessing the rehabilitation center, mainly due to distance, transport costs and conditions, and lack of companions. Health problems (e.g., surgeries, pain, and mobility difficulties) and lack of time due to work, commuting, and household work were also reported. Another reported theme was not perceiving the need for rehabilitation due to feeling well. Minor themes included the need for more information about rehabilitation and a lack of interest, motivation, and medical encouragement.

Conclusion

Individuals hospitalized for COVID-19 faced several barriers to participating in a pulmonary rehabilitation program. These barriers included difficulties in accessing the rehabilitation center, health problems, lack of time, and the perception that rehabilitation was unnecessary. There is a need for actions to overcome these barriers to make the program available to a larger number of individuals.
Learning in online and physical craft groups: Motivations and meanings
Authors: Gibson Miriam , Spronken-Smith Rachel
Published: November 2023

This study examines why people choose to participate in online and face-to-face craft groups and seeks to understand how the mode of participation impacts individual experience and meaning making. Data from eight semi-structured interviews, text analysis of 345 social media posts, and participant observation of four face-to-face craft group meet-ups are synthesized, resulting in identification of social, technical and expressive meanings that underpin motivation to participate in both online and physical groups. These three categories expand on previous research categorizing motivation and meanings related to physical craft groups, by considering the range of asynchronous making-related online activities. The processes associated with sharing and acquiring knowledge and skills in online and physical craft groups were compared, with online groups being considered more conducive to the sharing of explicit or ‘hard’ knowledge, and physical groups being more suited to the sharing of tacit or ‘soft’ knowledge.

News, business and politics: Evita in Italy – newsreels and cinema in a shared post-war agenda
Authors: Rey Ana Lía , Rodríguez Fernando Diego
Published: November 2023

Eva Perón’s trip to Italy in the summer of 1947 has prompted this research about the development of links between the Italian and the Argentine film industries in the years immediately following the Second World War. Our work takes a historical approach to this topic through the analysis of different film types (movies, newsreels and documentaries), supported by other documents derived from periodical publications, such as newspapers and specialized magazines. It concludes that while at the time of Evita’s trip there was an economic agreement between both governments that consisted of shipping grains in exchange for encouraging the migration of skilled Italian workers who could carry out the economic plans devised by Perón, in the film industry, there was an attempt to attract top class Italian actors and directors in order to secure the growth of the budding Argentine film industry.
Transnational asymmetries: Tracing the material history of 2 de octubre, aquí México and Histoire d’un document (Menéndez 1971)
Authors: Errazu Miguel
Published: November 2023

This article reconstructs the material history of a set of Super 8 films clandestinely shot in the Lecumberri prison of Mexico City in 1970, and eventually used for two films produced in France: 2 de octubre, aquí México (Menéndez 1971) and Histoire d’un document (Menéndez 1971). The article first addresses the production of these materials in the broader context of the 1968 Mexican student movement, and considers the impact of the Super 8 format for guerrilla filmmaking and Third Cinema. Secondly, it discusses the aesthetic, political and historical implications of Menéndez’s agreement with the Office de Radiodiffusion-Télévision Française (French Public Office of Radio and Television) (ORTF), and the differences between the two films. Finally, the article attends to his short stay in Italy during the winter of 1972 to explore the tensions, imbalances and asymmetries that traversed transnational exhibition and production networks of solidarity between Europe and Latin America.

Published: November 2023

Background and Aim: Working animals are important in agriculture because they play a role in various agricultural activities, including milk and meat production. Thus, they contribute to the development of rural communities. In this study, we aimed to evaluate the effects of different load weights on the work performance and the physiological and hematological responses of working water buffalo (Bubalus bubalis).

Materials and Methods: The work performances of 12 buffaloes (average weight 782.16 ± 21.62 kg) transporting 200, 350, and 500 kg of African palm fruits in metal baskets placed on their backs were evaluated. Work performance variables evaluated immediately after work were as follows: total number of trips (n), total weight (kg), distance traveled (km/day), working period (h), stopped time (h), and average speed (km/h). In addition, we evaluated physiological, biochemical, and hematological variables at three different times: before the start of work, immediately after work, and on the rest day.

Results: Among the load weights, 500 kg (total load carried = 4,138.88 kg) improved work efficiency compared to 200 kg loads (total load = 3,322.22 kg) (p = 0.0281). However, 500 kg loads resulted in slower average speed (2.4 km, p = 0.0164), shorter working period (2.39 h, p < 0.0001) and distance traveled (7.29 km, p < 0.0001), and less total number of trips (8.27 trips, p < 0.0001) compared to 350 and 200 kg load weights (3.45 and 3.52 km/h, 2.55 and 2.79 h, 8.71 and 9.75 km, 10.94 and 16.61 trips, respectively); and the heaviest loads resulted in significantly higher (p < 0.005) respiratory rate, pulse, heart rate, rectal temperature, glucose, lactate dehydrogenase, creatine kinase, total protein, white blood cell count, neutrophils, lymphocytes, monocytes, eosinophils, and basophils. In contrast, was associated with lower levels of red blood cells, hemoglobin, and hematocrit compared to lower loads. All differences were more pronounced in 500 kg (p < 0.005) compared to 200 kg loads.

Conclusion: Working buffaloes responded to work related to the transport of African palm fruits through various physiological, biochemical, and hematological changes. However, some variables remained close to the reference values reported in the literature for water buffaloes, and in general, all variables were reestablished during the rest day, indicating that these animals have adapted to working conditions.

Keywords: biochemical responses, draught buffalo, hematological responses, physiological responses.

Published: November 2023

Cultural heritage building information modeling (HBIM) is an emerging process allowing us to reconstruct built heritage virtually. The data of a digitally documented cultural heritage building offers significant advantages as it is accessible and modifiable by all professionals involved
in the same or different projects. The most important factor affecting the accuracy and precision of the HBIM model is the ability to collect complete and accurate information about the physical structure. Combining terrestrial laser scanning (TLS) and unmanned aerial vehicle (UAV) photogrammetry
point clouds is one of the most efficient ways to capture accurate digital data on the building. This study provides the foundation for creating an HBIM model for cultural heritage the coupling of spatial data with TLS and UAV. This paper aims to generate synergy between TLS and UAV point
cloud data and ensure that the spatial database contains sufficient data to model historical objects with HBIM tendencies.

MATHEMATICAL MODEL OF ELECTRO-MECHANICAL VIBRATION TRANSDUCERS BASED ON THE LEVITATION EFFECT
Authors: Shilin A. N. , Makartichyan S. V. , Mustafa M. N.
Published: November 2023

At present, one of the urgent problems in the energy and industry is to improve the reliability of the operation of various equipment. An effective method for increasing the reliability of equipment is diagnosing the state of machines and predicting their performance. Vibration control methods are widely used to diagnose rotary rotating machines. By the nature of the vibration process of the machine, it is possible to determine the degree of wear and, accordingly, the technical condition of the machines. In measuring technology for diagnostics of low-speed equipment with rotation frequencies of a unit of Hz, for example, hydroelectric generators of hydroelectric power plants, inertial electromechanical converters are used. The latest developments of such converters use an electromagnetic suspension with parametric feedback, which allows you to control the rigidity of the oscillatory system. However, for centering the moving part in electromechanical converters, flexible guides are used, which are sources of dry friction, which complicates the simulation of measurement processes and limits the sensitivity threshold to a minimum. In addition, flexible guides limit the frequency range of the converters. Currently, the most promising direction for solving this problem is the levitation effect, which allows you to completely exclude mechanical contact and, accordingly, reduce the sensitivity threshold of the transducer. From the analysis of literary sources, it follows that there are relatively few publications in this area. This article provides an analysis of existing vibration transducers and proposes a mathematical model of the magnetic levitation system, taking into account the influence of the electromagnetic force nonlinearity, as well as a method for selecting the feedback control unit parameters to stabilize the mass position of the vibration sensor.

METROLOGICAL SUPPORT FOR THE VERIFICATION OF MERCURY THERMOMETERS
Authors: Golobokov M. V.
Published: November 2023

Modern liquid thermostats used for checking mercury thermometers reproduce a temperature of no more than 300 °C, while the upper limit of measurements of some types of mercury thermometers reaches 600 °C. The paper theoretically substantiates and experimentally confirms the possibility of checking mercury thermometers in temperature calibrators. The measurement equation has been compiled. The components of the transmission error of the unit of magnitude are estimated. Conditions are formulated that allow a priori to assess the possibility of checking a particular type of thermometer in a particular calibrator. All calculations are made taking into account the changes in the state verification scheme. The design of a special thermometer for studying the heterogeneity of the temperature distribution outside the working area of the calibrator channel is proposed. The dependence of the readings of a special thermometer on the depth of immersion is theoretically estimated. The disadvantages of the currently used method for determining the temperature of the protruding mercury column are noted. It is proposed to measure the temperature of the protruding column with a thermal imager, an accuracy analysis is performed. The results of experimental studies of the inhomogeneity of the temperature distribution outside the working area of the channel of the calibrator KT-2M are presented. The reproducibility of measurement results when checking thermometers in a calibrator and a liquid thermostat is estimated.

Authors:   Economic Research Institute FEB RAS, Prokapalo Olga
Published: November 2023

On the basis of operational statistical, analytical and expert information, an analysis of the economic and social situation in the Far Eastern Federal District is carried out in the first half of 2023 compared to 2021–2022. It is shown that while maintaining instability and conflicting development trends in certain sectors of the economy, there is no galloping decline in the macroeconomic context. The maintenance of slightly negative rates in the Far Eastern Federal District industry in the first half of 2023 was noted, which is associated with negative trends in the manufacturing sector of the economy in January – May, a decrease in which could not compensate for the renewed growth of extractive industries in May – June. Positive dynamics and growth of investments in fixed assets remain, which is associated with anti-crisis measures of state regulation and financing of large investment-intensive infrastructure projects. As before, the main volume of investment resources is accumulated in the Republic of Sakha (Yakutia) and the Amur Region, where the implementation of large anchor investment projects in the field of mining, transport, gas chemistry, energy continues. In the construction complex, for the second year, positive dynamics remains associated, among other things, with the expansion of housing construction with the support of mortgage lending and budget incentives. There is a slow recovery in consumer demand in certain categories due to the growth of real incomes of the population against the background of low inflation

Generating personalised profiles of student engagement to predict student performance and support student learning using LMS data
Authors: Pinar Ari , Choate Julia
Published: November 2023

With the rising popularity of delivering educational content in the online space, this study set out to better understand how students are increasingly engaging with Learning Management Systems (LMSs) for their learning (Gupta, Muralidharan, & Raghavan, 2021; Henrie, Halverson, & Graham, 2018; Conijn, Snijders, Kleingeld, & Matzat, 2017).

A data mining approach was used to investigate whether student activity data from LMSs could be used, first in generating profiles of student engagement and, second, in predicting student academic performance (Romero & Ventura, 2013; Tempelaar, Rienties, & Giesbers, 2015; Conijn et al., 2017).

LMS activity data was collected throughout a semester for a cohort of undergraduate students (N=534) enrolled in a biomedical science subject. This activity data comprised of total views and downloads of lecture recordings and average time spent viewing lecture recordings, total number of page clicks, total number of LMS course and content page clicks (e.g., lecture lessons), total number of discussion forum posts and views, and total number of formative quiz attempts and reviews (Wang, Chen, & Anderson, 2019; Conijn et al., 2017). K-means cluster analysis was performed to generate profiles of student engagement using this digital LMS data. Measures of student activity derived from this digital LMS data were used to predict academic performance (students' final unit totals), using linear regression and ANOVA.

We demonstrate the utility of LMS log data in constructing 'profiles' of student engagement, and in establishing predictors of academic performance. In line with existing literature, average time spent viewing lecture recordings was determined to be a significant predictor of academic performance. Clustering analyses revealed three distinct clusters, or ‘profiles’ of student engagement, each representing key differences in student engagement activity, with greater homogeneity in student engagement behaviour within clusters, and greater heterogeneity across clusters.

The current findings provide valuable insights on how our students are increasingly engaging with LMSs for their learning. As delivery of education towards the online space continues to gain momentum, evidence-based approaches such as those utilized in this study will help inform and enhance teaching practices (Jovanovi?, Gaševi?, Pardo, & Dawson, 2020; Ullmann, Wild, & Scott, 2018; Conijn et al., 2017). A better understanding of how students are differentially engaging with LMSs will also help support the development of teaching resources that more closely mirror and complement online student learning behaviors (Dyckhoff, Zielke, Bültmann, Chatti, & Schroeder, 2013; Conijn et al., 2017).
AI-powered peer review process
Authors: Oliveira Eduardo , Rios Shannon , Jiang Zhuoxuan
Published: November 2023

Code review is a common type of peer review in Computer Science (CS) education. It’s a peer review process that involves CS students other than the original author examining source code and is widely acknowledged as an effective method for reducing software errors and enhancing the overall quality of software projects. While code review is an essential skill for CS students, they often feel uncomfortable to share their work or to provide feedback to peers due to concerns related to coding experience, validity, reliability, bias, and fairness. An automated code review process could offer students the potential to access timely, consistent, and independent feedback about their coding artifacts. We investigated the use of generative Artificial Intelligence (genAI) to automate a peer review process to enhance CS students’ engagement with code review in an industry-based subject in the School of Computing and Information System, University of Melbourne. Moreover, we evaluated the effectiveness of genAI at performing checklist-based assessments of code. A total of 80 CS students performed over 36 reviews in two different weeks. We found our genAI-powered reviewing process significantly increased students’ engagement in code review and, could also identify a larger number of code issues in short times, leading to more fixes. These results suggest that our approach could be successfully used in code reviews, potentially helping to address issues related to peer review in higher education settings.
Deeper student-teacher partnership in 5 steps
Authors: Li Melody(Pei) , Ling Gee Chong , Turnbull Kristin
Published: November 2023

Students as Partners initiatives have the potential to enable students and staff to collaborate on improving the teaching and learning experience (Mercer-Mapstone et al., 2017). Following two iterations of a students as partners initiative applied across different disciplines to enhance student-teacher partnership, an implementation strategy was established through a 5-steps process of recruitment, active listening, review, co-design, and evaluation. The proposed model established deeper partnership during the learning process, delivering significant changes that enhanced students’ learning instead of the typical iterative design at the end of the learning period (course). The partnership contributed to student partners’ development through an experiential learning process. Integrating learning theories and practices with human-centered design, we explore the research question: How do we nurture a deep student and teacher partnership for positive impact? Underpinned by Argyris & Schön’s (1974) double loop learning and design thinking the 5-steps approach resulted in greater student experience and satisfaction, enabled the development of a sense of community and personal development for student partners and course convenors.

This paper draws upon the authors' extensive experience in designing and delivering simulation-based courses in both Australia and New Zealand. Through their first-hand experience, they have found that simulation-based courses offer distinct advantages compared to traditional pedagogical approaches. Participants in these courses exhibit enhanced learning and retention due to their active engagement and sense of ownership in the learning process. By adopting a "hands-on" approach, the majority of course time is dedicated to experiential learning and discovery rather than passive listening (Garris, Ahlers & Driskell, 2002).

The purpose of this article is to present and elaborate on how simulations can be used in business education along with insights the authors have gained over the years. In most business simulations, learners are immersed in the role of managing a firm within a competitive environment(s), engage in competition with other firms operating in the same industry, and strive to effectively produce, market goods, and optimize resource management for sustainable growth. Throughout the process of completing the simulation students have noted that they not only expand their business knowledge but also improve their employability skills, particularly teamwork, problem solving, communication and critical analysis. This paper also reflects on the relationships built throughout the simulation course.

Many students enter mathematically intensive courses with deficiencies in their mathematical skills. Universities have responded to this challenge with additional support. However, existing approaches have exhibited limited success. This paper proposes research into the effectiveness of a personalised approach to mathematical remediation driven by the affordances of EdTech.
IDE vs. pen-and-paper showdown - Performance and perceptions of testing first-year IT students’ programming skills
Authors: Harris David , Von Itzstein Garry Stewart , Kelly Douglas , Smith Elizabeth
Published: November 2023

This study analysed first-year IT students' performance and perceptions of using Integrated Development Environment (IDE) versus pen and paper (P&P) based programming testing methods. 68 participants completed two programming tests using both testing methods, and the results were evaluated on complexity, quality and other criteria. No significant difference was observed in the average scores between the two test methods. However, IDE testing showed fewer syntax errors and lower cyclomatic complexity, indicating the potential advantages of IDE's error-checking. IDE tests exhibited higher variability in student performance, suggesting varying comfort levels with the test environment. Additionally, a weaker correlation existed between actual and perceived performance in IDE tests, highlighting challenges in self-evaluation within a digital framework. Most students preferred IDE-based testing, citing efficiency, user-friendliness, and real-time feedback. Nonetheless, a minority recognised the value of P&P tests for demonstrating deep syntax understanding. This research enhances our understanding of programming pedagogy and assessment.

This poster will give insights into the Instructional Designer team's journey in evolving its methods for developing online courses. It will cover the transition from academic support to designing MOOCs on external platforms and developing courses for an in-house Learning Management System. A key aspect is the focus on targeting a different kind of learner moving beyond the traditional university student. The poster will look at the challenges, successes, and lessons learned throughout this transformation, underlining the processes, pedagogical approaches, partnerships involved as well as the challenges yet to come.
Developing a digital anatomy lab for rural medical students

Published: November 2023

This paper follows the genesis and development of a digital anatomy lab for geographically isolated students in a postgraduate Doctor of Medicine programme in rural New South Wales and represents a work in progress. Students studying their degree at the rural clinical school do so without an in-situ cadaver-centred anatomy laboratory.  This represents a pivotal shift away from the fundamental learning pedagogies implicit in academic Medicine, and therefore a challenge for situating the digital anatomy lab; its contents and explicit pedagogical needs, inside an already saturated curriculum.  The Digital Anatomy space under development represents an intersection of scholarship on whether nascent digital tools (VR/AR) can develop fast enough to provide haptic and spatial feedback, how such digital spaces sit pedagogically amidst the accepted didactic teaching frameworks of Medicine, and whether creating virtual spaces improves student learning of Anatomy.  This work-in-progress reflects the conference themes of people, partnerships and pedagogies.
Firenze, 1295–1301: Dante, la politica e i partiti
Authors: Barbero Alessandro
Published: November 2023

Zuammenfassung

Eine Untersuchung der sechs Jahre, in denen Dante von 1295 bis 1301 aktiv am politischen Leben der Kommune Florenz teilnahm, zeigt, dass der Dichter seinem politischen Engagement große Bedeutung beimaß und schnell eine führende Position in der gemäßigten Volksregierung einnahm, die die Geschicke der Stadt lenkte. Er verfügte über alle notwendigen Voraussetzungen, um zu diesem spezifischen Zeitpunkt die politische Szene erfolgreich zu betreten: Er stammte aus dem Volk, aus einer Familie, die den Guelfen angehörte, war aber durch verwandtschaftliche und freundschaftliche Bande mit der Welt der Magnaten verbunden, denen sich die gemäßigten Guelfen zu jener Zeit annähern wollten. Und er hatte bei Brunetto Latini die Kunst der öffentlichen Rede und des Verfassens offizieller Briefe gelernt. Die zahlreichen Anlässe, bei denen er in den Räten das Wort ergriff, um fast immer die Vorschläge der Regierung zu unterstützen, zeigen, dass er deren volles Vertrauen genoss. Zum Verhängnis wurde ihm die Spaltung der Guelfenpartei in die gegensätzlichen Richtungen der Weißen und der Schwarzen: Seine Entscheidung, sich den Weißen anzuschließen, brachte ihn während der kurzen Phase ihrer Vorherrschaft mit seiner Ernennung zum Prior im Sommer 1300 an die Spitze der Kommune, kostete ihn aber nach dem Staatsstreich der Schwarzen Ende 1301 das Exil.
Politische Ikonographie der Kommune zur Zeit Dantes

Riassunto

Questo contributo esamina vari esempi di iconografia politica nei comuni dell’Italia settentrionale dei secoli XIII e XIV. Tra questi, l’epigrafe del Bargello di Firenze composta da Brunetto Latini, i resti di affreschi nel Palazzo della Ragione milanese, le fontane di Nicola e Giovanni Pisano, e quella di Arnolfo di Cambio a Perugia e l’affresco, oggi perduto, del Comune rubato di Giotto. Si tratta di un’iconografia che si serve soprattutto delle figure dell‘araldica e di svariate tecniche allegoriche.
Updated statistics on Influenza mortality
Authors: Mattiuzzi Camilla , Henry Brandon M. , Lippi Giuseppe
Published: November 2023

We have planned this analysis to provide current statistics on mortality directly caused by Influenza viruses in recent years in the US. We performed an electronic search in the online database CDC WONDER to obtain current statistics on direct mortality caused by Influenza viruses in the US. Mortality data are derived from information on all death certificates issued in the 50 states and the District of Columbia, excluding deaths of nonresidents. Our basic query criteria included Influenza-specific ICD-10 codes. Influenza caused an average of 7,670 deaths per year from 2018 to 2020 based on Influenza-specific ICD-10 codes, with a corresponding mean death rate of 2.3 × 100,000. The death rate increased in parallel with the age of the US resident population, from 0.2 × 100,000 in the 5–24 age group to 37.4 × 100,000 in US residents aged 85 years or older. No substantial differences were observed in males vs. females. The results of this analysis show that Influenza remains a significant clinical burden in the general population, with a cumulative mortality rate of approximately 2.3 × 100,000, but increasing more than tenfold (to over 37 × 100,000) in older persons.
The UCTD 30 Years Later: Identifying and Blacklisting Unfair Terms in Digital Markets
Authors: Poncibò Cristina
Published: November 2023

Thirty years since it entered into force, the Unfair Contract Terms Directive (‘UCTD’) needs updating to address the challenges posed by digital services. This concerns in particular the fundamental research question of identifying new unfair terms of digital service providers (‘DSPs’) so that they can be included in a new blacklist. These challenges are central to the ongoing EC study named ‘Fitness Check of EU Consumer Law’ concerning the evolution of consumer law in the digital age, and promoting a fair and transparent environment for consumers in an ever-changing digital landscape. The article identifies digital-specific unfair terms used by DSPs and organises them into four main themes (i.e., digital services and contents, automation and personalisation, price & free services, and consumers’ data rights). It also discusses the methodological approaches adopted by institutions and researchers in detecting such types of unfair terms in digital environments. Finally, the article examines the possible regulatory options and, particularly, the possibility of establishing a new blacklist of digital-specific unfair terms and/or developing EC guidelines for fairness assessment under the UCTD.
Detection and characterization of lineaments using gravity data in the south-west Cameroon zone: Hydrogeological implications

Published: November 2023

In Cameroon, the drying up of wells and boreholes during the dry season is characterized by a lack of knowledge about the surface structures of the subsoil and the spatial distribution of groundwater. In this study, we propose to use gravity data to detect and characterize the surface structures of the south-west (SW) Cameroon and to analyze their hydrogeological implications. The application of the normalized standard deviation method on the data obtained from the stable downward continuation of the Bouguer anomalies led to the detection of 71 lineaments that characterize the tectonic events of the study area. The statistical analysis of the lineament directions shows that the near-surface structures were mainly affected by a tectonic of direction east–west followed by that oriented SW-north-west. These two directions are consistent with the megastructures in the region like the Ngoro-Belabo Shear Zone and the Sanaga Fault stretching from the Gulf of Guinea to the Central African Republic. In addition, the application of the Euler deconvolution method permits us to evaluate the interval in which lies the depth of each lineament hosting Euler solutions. The analyses showed that 12 lineaments, whose roof depths are between zero and 250 m, are very favorable for hydrogeological prospecting.
On the design of international match calendar: the effect of “FIFA reserved dates” on European football matches’ outcomes
Authors: Pérez Levi
Published: November 2023

Every season, the international football calendar contains periods reserved for a series of so-called special matches including international friendly or official matches played by national teams. All these periods are called “FIFA reserved dates” in the calendar and generally cause domestic competitions to shut down for some days. Such interruptions of leagues might generate different effects or externalities on the performance of players, clubs or even on the competition itself. While a number of studies focus on the effect of players’ absence on teams performance, this paper contributes to the literature by specifically evaluating the effect of the “FIFA reserved dates” on football outcomes. Using data for four seasons from the “big five” European leagues, I find evidence that the outcomes distribution in those matches played after a “FIFA reserved date” becomes more balanced, thus increasing the uncertainty of outcome. The results of this paper contribute to the ongoing debate about the management and design of the international match calendar.
