The term well-being in Technology-Enhanced Learning: A systematic literature review

Well-being as a concept has a wide spectrum, easily gaining an interdisciplinary quality more often than not. Its concurrent use in education is more prominent now, gaining relevance due to the discussions surrounding the ethical guidelines for the design of digital technologies and Artificial Intelligence (AI). This paper presents a systematic literature review aiming to explore the gray area that is the use of the word “well-being”. The objective is to look further into the uses of the word, its formulated expressions, conceptualizations and areas of impact that are specifically focused and linked to Technology-Enhanced Learning (TEL). We find that the word “well-being” comes in various shapes and forms, sometimes accompanied by supporting expressions (e.g. emotional well-being, mental well-being) and other times used alone to address the state of wellness of a person. The results provided in this paper focus on the specific dimensions of well-being impact in TEL and are mainly classified by the identified contexts of use.
Antenna radiation pattern of cyclotron harmonic waves in a hot magnetoplasma

The near and far field radiation pattern of a very short antenna is studied in the plasma regime. ωc < ω < 2ωc, ωp ≫ ωc (where ωp and ωc are the electron plasma and cyclotron frequencies, respectively). The experiment is performed in a large laboratory magnetoplasma. Cyclotron harmonic waves are detected in all directions, not only those corresponding to the purely perpendicular direction of detection as was observed previously. This new result is theoretically explained and studied in detail. Constant phase curves deduced from the dispersion relation for a hot Maxwellian electron magnetoplasma are considered. They are found to be described by the low damped part of the polar dispersion curves. The different shapes of the wave surfaces (convex and concave with respect to the excitation source) are in good agreement with experimental results. The effects of plasma and magnetic field inhomogeneities on the dispersion relation are discussed. Experimental isoamplitude curves are presented in the whole space around the transmitter. The theoretical dispersion curves show that the energy of the cyclotron harmonic waves tend to propagate principally outside a cone whose apex is the transmitter and whose axis is parallel to the direction of the magnetic field. The theoretical opening angle of this cone is given by the direction of the group velocity at the inflexion point of the polar dispersion curve where the Landau damping increases suddenly. This theoretical result is in reasonable agreement with the spatial distribution of energy observed experimentally. From this study it is shown that the simple dispersion relation for perpendicular propagation can be used to predict qualitatively the distribution of cyclotron harmonic waves in all directions for dense magnetoplasma conditions.
Social Anxiety Disorder: Associated Conditions and Therapeutic Approaches

Social anxiety disorder (SAD) is a highly distressing chronic psychiatric disorder characterized by persistent fear of social situations in anticipation of being judged negatively by others. As shyness mimics some of the symptoms of SAD, people suffering from this debilitating disease are often underdiagnosed. It can have a devastating impact on all areas of life including academic performance, social growth, relationship status, and work performance. In recent years, research on anxiety and related disorders has proliferated due to the increased use of cognitive-behavioral models. The understanding of SAD has evolved greatly from distinguishing it from shyness to implementing modalities to comprehend the sophisticated underlying mechanism of disease prevalence and progression as well as methods to treat it. This review summarizes the concept of SAD, its epidemiology, symptoms, and diagnostic tools. Frequent comorbidities including other psychiatric disorders are also discussed. Additionally, we examine the latest evidence related to treatment options including psychotherapy and pharmacotherapy as well as recommendations for managing SAD.
Monitoring of evolution of resistance to commercial acaricidal products in Rhipicephalus sanguineus sensu lato (Latreille, 1806) (Acari: Ixodidae) from Goiânia, Goiás State, Brazil

The Brown dog tick Rhipicephalus sanguineus is the most reported and geographically widely spread tick in the world, presenting a great medical and veterinary importance, mainly because the ability to transmit various diseases to its hosts, causing great harm to pets, but also risks to public health, due to the transmission of emerging pathogens to humans. In order to monitor the resistance or susceptibility of R. sanguineus to acaricides, and contribute to integrated control measures for this vector, the activity of 14 commercial acaricidal products on larvae from the city of Goiânia, Goiás, Brazil were studied. Although these products are already sold as acaricides, their cost-benefit efficiency has been questioned by dog breeders and kennel owners. R. sanguineus larvae were obtained from engorged females collected in naturally infested urban environments. The susceptibility of the larvae was evaluated by the larval packet test (lpt) method. Bioassays were carried out in quadruplicate, at 27 ± 1oC, RH ≥ 80% and photoperiod of 12 hours. About 50 larvae, from 14 to 21 days of age, were conditioned in filter paper envelopes, impregnated with different concentrations of acaricide products, obtained from dilution of stock solutions. The control group used the same amount of larvae, submitted to envelopes treated only with distilled water. A status of resistance of R. sanguineus larvae to acaricide formulations was evidenced for Cypermethrin, Cypermethrin + Piperoline Butoxide, Deltamethrin, Permethrin (after 24h of exposure), in the dosages recommended by the manufacturing laboratories, as they promoted a mean mortality of only 58.36%, 71.36%, 48.7%, and 64.5% of the submitted larvae, respectively, Amitraz providedof only 78.8 and 88.00% (After 24 and 48 hours of exposure to the acaricide, respectively), characterizing a status of possible development of resistance to this acaricide. The other evaluated products (Dichlorvos + Cypermethrin, Chlorfenvinphos + Dichlorvos + Alkyl + Xylol, Chlorpyrifos + Cypermethrin hi-cis, Fipronil, Chlorpyrifos, Cypermethrin + Chlorpyrifos + Citronellal, and Trichlorfon + Coumaphos + Cyfluthrin; and Diazinon) showed higherindices, configuring the susceptibility status to these acaricide formulations. No significant mortality was found in the control groups. The ideal concentrations to kill R. sanguineus larvae (CL99) referring to products that showed low acaricidal activity were statically calculated and are presented in this study. The present work, confronted with previous studies, ratified the real evolution of resistance to synthetic chemical acaricides in local populations of R. sanguineus.
Parameter Analysis and Normalization for the Dynamics and Design of Multibody Systems

In this paper, we introduce a novel concept for parametric studies in multibody dynamics. This includes a technique to perform a natural normalization of the dynamics in terms of inertial parameters. This normalization technique rises out from the underlying physical structure of the system and the trajectory investigated. This structure is mathematically expressed in the form of eigenvalue problems. It leads to the introduction of the concept of dimensionless inertial parameters. This, in turn, makes it possible to introduce an analysis approach for studying design and control problems where parameter estimation and sensitivity are of importance.
Vagus Nerve Stimulation: A Personalized Therapeutic Approach for Crohn’s and Other Inflammatory Bowel Diseases

Inflammatory bowel diseases, including Crohn’s disease and ulcerative colitis, are incurable autoimmune diseases characterized by chronic inflammation of the gastrointestinal tract. There is increasing evidence that inappropriate interaction between the enteric nervous system and central nervous system and/or low activity of the vagus nerve, which connects the enteric and central nervous systems, could play a crucial role in their pathogenesis. Therefore, it has been suggested that appropriate neuroprosthetic stimulation of the vagus nerve could lead to the modulation of the inflammation of the gastrointestinal tract and consequent long-term control of these autoimmune diseases. In the present paper, we provide a comprehensive overview of (1) the cellular and molecular bases of the immune system, (2) the way central and enteric nervous systems interact and contribute to the immune responses, (3) the pathogenesis of the inflammatory bowel disease, and (4) the therapeutic use of vagus nerve stimulation, and in particular, the transcutaneous stimulation of the auricular branch of the vagus nerve. Then, we expose the working hypotheses for the modulation of the molecular processes that are responsible for intestinal inflammation in autoimmune diseases and the way we could develop personalized neuroprosthetic therapeutic devices and procedures in favor of the patients.
Trends of intestinal parasites among the patients attended at Yabelo General Hospital, Borena Zone, Southern Ethiopia

Objectives: Intestinal parasitic infections (IPIs) still cause a major public health problem in developing countries. The most affected populations are those with low socioeconomic status, lack of latrines, inadequate water supply, and poor hygiene like in pastoralist community areas in Ethiopia. Therefore, the study assessed the trends of intestinal parasites among the patients attended at Yabelo General Hospital, Southern Ethiopia, from 2019 to 2021. Methods: This retrospective study was conducted on 6108 patients and recorded data from Yabelo General Hospital, which were extracted using a checklist. The complete data of sex, age, and laboratory stool examination result in the record book were included in the study. The data were double-entered using EpiData version 3 and exported to the Statistical Package for Social Sciences version 16 for analysis. The associated factors were analyzed using chi-square and a p-value <0.05 was considered statistically significant. The results were presented in tables, pie charts, and graphs. Results: The overall prevalence of intestinal parasites among the patients who attended Yabelo General Hospital was 48%. Of these, 37.8% (2310) were intestinal protozoa, and 10.2% (624) were intestinal helminths. The study indicates that 59% of patients aged above 45 years were seen infected with intestinal parasites. Of the total suspected patients, 2% (123) were found to have mixed parasite infections. The most reported parasites were Entamoeba histolytica/Entamoeba Dispar 22.6%, Giardia lamblia 15.3%, and Ascaris lumbricoides 1.8%. The trend analysis of intestinal parasites revealed that the overall prevalence declined from 55% in 2019 to 42.3% in 2021. Conclusion: The prevalence of IPI was high among patients seen at Yabelo General Hospital. The analysis showed that the prevalence declined from 2019 to 2021. To sustain the decrease in prevalence, all intestinal parasite prevention measures should be continuously exercised in the area.
A general theory for matrix root-clustering in subregions of the complex plane

We consider the general problem of root-clustering of a matrix in the complex plane: Let A \in C^{n \times n} and S \subset C . Find the largest class of S and an algebraic criterion which is necessary and sufficient for \lambda_{i}[A] \in S, i=1,2,. , n . We introduce two types of regions which constitute the largest class of S known to date. The criterion is presented both for open regions and closed ones. The results are used to define a design methodology for control systems. Moreover, all classical results are shown to be special cases of the present theory.
Simulation studies of positron acceleration by a shock wave

Using a relativistic electromagnetic particle code, we investigate positron acceleration in a shock wave propagating obliquely to an external magnetic field ${\bf B} _0 $ in an electron–positron–ion plasma. After an encounter with a shock wave, some positrons are reflected and then accelerated along the magnetic field. They stay in the shock transition region and have velocities nearly parallel to ${\bf B} _0 $. Owing to the deformation of the wave profile, the acceleration can become stagnant. However, if the shock speed $v_{\rm sh}$ is close to $c \cos \theta $, where $c$ is the speed of light and $\theta $ is the angle between the wave normal and ${\bf B} _0 $, the acceleration can start again. In this second stage acceleration, three types of motion are found. The first type is the same as that in the first stage. In the second type, particles gain energy from the electric field perpendicular to the magnetic field in association with large-radius gyromotion. The third type of motion resembles the curtate cycloid in the wave frame. We give theoretical estimates for the energy increase in these processes.
Adherence to safety precautions in the operation theatre among anaesthesiologists in the COVID era

Background and Aims: The COVID-19 pandemic led to significant infections among healthcare workers and deaths warranting the need for personal protective equipment. This study aimed to estimate the proportion of anaesthesiologists adhering to safety precautions and to evaluate their adherence patterns, difficulties faced and coping mechanisms in the operation theatre during the pandemic. Methods: This was a multicentric mixed methods study conducted among anaesthesiologists from two tertiary care hospitals. A paper-based questionnaire was given to all participants. The first part consisted of 21 questions regarding safety measures and extent of adherence. The second part was a response sheet regarding the various difficulties faced and coping mechanisms adopted. Following this, an in-depth interview was conducted to understand the same. The proportion of anaesthesiologists in different categories of adherence, patterns of adherence, difficulties faced, and coping mechanisms were computed and compared. Thematic framework analysis was done for in-depth interview. Results: Sixty participants were included. The adherence levels for N95 masks and face shields were higher. Most participants practised frequent handwashing and took showers after work. Fogging, difficulty in communication, marks on the face were the commonly faced difficulties. Self reassurance, adjusting the fit of masks/face shields, or taking breaks were the coping mechanisms mostly followed. Themes generated from in-depth interview include waning of caution, adaptation through innovative methods and stress due to uncertainty. Conclusion: The N95 mask was the most preferred safety precaution. Ease of use and safety were important considerations for adherence. Physical and mental acclimatisation and improved knowledge of disease played a vital role.
Global linear stability analysis of falling films with inlet and outlet

Abstract In this paper, the stability of falling films with different flow conditions at the inlet is studied. This is done with an algorithm for the numerical investigation of stability of steady-state solutions to dynamical systems, which is based on an Arnoldi-type iteration. It is shown how this algorithm can be applied to free boundary problems in hydrodynamics. A volume-of-fluid solver is employed to predict the time evolution of perturbations to the steady state. The method is validated by comparison to data from temporal and spatial stability theory, and to experimental results. The algorithm is used to analyse the flow fields of falling films with inlet and outlet, taking the inhomogeneity caused by different inlet conditions into account. In particular, steady states with a curved interface are analysed. A variety of reasonable inlet conditions is investigated. The instability of the film is convective and perturbations at the inlet could be of importance since they are exponentially amplified as they are transported downstream. However, the employed algorithm shows that there is no significant effect of the inlet condition. It is concluded that the flow characteristics of falling films are stable with respect to the considered time-independent inlet conditions.
Changes in Trust in Automation (TIA) After Performing a Visual Search Task with an Automated System

Humans must increasingly partner with automation in complex systems such as self-driving vehicles, assembly lines, assisted surgery, and autopilot in next-generation aircraft. The present study measured TIA alongside dispositional (Propensity to Trust machines; PTT) trust and situational (task difficulty) factors believed to impact TIA. People completed a conjunction visual search task with and without the help of an automated system and made subjective assessments of task difficulty after each trial. TIA and PTT machines were assessed at the beginning of the study, and TIA was assessed again at the end. Findings indicated a significant decrease in TIA scores over time and a significant positive relationship between peoples’ PTT machines and average TIA scores. However, PTT machines did not affect pre- or post-experiment TIA differently. Additionally, our findings did not provide support for a relationship between subjective assessments of task difficulty and TIA, likely due to the aggregate nature of these measurements. These results confirm that performing a task with an automated system allows for the development of learned trust and that PTT machines is an important dispositional factor affecting TIA. These findings increase our understanding of how dispositional, situational, and learned factors affect TIA when captured together. These findings also underscore the importance of studying these factors simultaneously, as this is how trust is built and shifted in real-world environments.
Comparison of the Efficacy and Safety of Transarterial Chemoembolization Plus Microwave Ablation versus Surgical Resection in Patients with Solitary Large Hepatocellular Carcinoma: A Propensity Score-Matched Analysis

Background The liver resection for solitary large hepatocellular carcinoma (SLHCC) remains controversial due to the high risk of complications and recurrence after resection. This study aimed to compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) plus microwave ablation (MWA) with resection for SLHCC. Methods We retrospectively analyzed a total of 148 patients who were treated with either TACE-MWA (n = 94) or resection (n = 54) for SLHCC (≥5 cm). A matched cohort composed of 86 patients was included after propensity score matching (PSM). The primary endpoint was overall survival (OS), and the secondary endpoints were progression-free survival (PFS) and safety. Results The TACE-MWA group was older with higher ALT and AST (all P < 0.05). After PSM, the 1-, 3-, and 5-year OS were 100%, 80.3%, and 51.0% in the TACE-MWA group, and 88.3%, 66.7%, and 39.4% in the liver resection group, respectively. The 1-, 3-, and 5-year PFS were 76.7%, 48.8%, and 19.6% in the TACE-MWA group, and 72%, 40.2%, and 22.6% in the liver resection group, respectively. There was no significant difference in OS and PFS between the two groups (all P > 0.05). For SLHCC patients with tumor size ≥7cm, TACE-MWA showed favorable OS than liver resection. The TACE-MWA group exhibited a lower rate of major complications and shorter hospital stay than the resection group. Conclusion TACE-MWA showed comparable efficacy to liver resection in patients with SLHCC, but better safety and shorter hospital stay. TACE-MWA might provide a longer OS than liver resection for SLHCC patients with tumor size ≥7cm.
Making the intangible tangible in sport heritage: a conceptual analysis of sport statuary’s spatial fix

ABSTRACT Sport heritage scholarship has grown in recent years, yet remains underexamined within the sport tourism field. In this conceptual analysis, we examine a type of tangible immovable sport heritage (Ramshaw [2020]; Ramshaw & Gammon [2017]) – sport statuary – that has a niche yet robust body of literature through the lens of the ‘spatial fix’ (Harvey [1981]; [2001]; [2006]) in an attempt to explain the value both of sport heritage as a domain worthy of further investigation and the spatial fix as a useful tool for future conceptual and empirical analyses within sport tourism. Three themes were identified from the sport statuary literature through the spatial fix lens: marketing implications of sport statuary, location implications of sport statuary, and sport statuary as an instrument to frame symbolic heritage, the latter of which is the overarching theme. The current paper makes two contributions to the literature. First, it posits the spatial fix to account for both the economic value of sport heritage phenomena and their presence in space, particularly urban space. Second, following guidance that has emerged from the literature of sport tourism’s allied disciplines of management and marketing, this paper also represents an attempt toward a framework to be used in future conceptual scholarship within the field. An important implication is that the spatial fix appears to be inherent to the process of making intangible sport heritage tangible, as demonstrated through the sport statuary literature.
Climate Change Amelioration by Marine Producers: Does Dominance Predict Impact?

Climate change threatens biodiversity worldwide, and assessing how those changes will impact communities will be critical for conservation. Dominant primary producers can alter local-scale environmental conditions, reducing temperature via shading and mitigating ocean acidification via photosynthesis, which could buffer communities from the impacts of climate change. We conducted two experiments on the coast of southeastern Alaska to assess the effects of a common seaweed species, Neorhodomela oregona, on temperature and pH in field tide pools and tide pool mesocosms. We found that N. oregona was numerically dominant in this system, covering >60% of habitable space in the pools and accounting for >40% of live cover. However, while N. oregona had a density-dependent effect on pH in isolated mesocosms, we did not find a consistent effect of N. oregona on either pH or water temperature in tide pools in the field. These results suggest that the amelioration of climate change impacts in immersed marine ecosystems by primary producers is not universal and likely depends on species’ functional attributes, including photosynthetic rate and physical structure, in addition to abundance or dominance.
