Authors: Shaheema Aishath , Azar Ali Sorayyaei , Ahmad Albattat
Published: August 2023

This conceptual paper is based on the review of literature on Self-Regulated Learning (SRL), its elements and link to performance in Mathematics. Over the past decades, SRL has been studied extensively. According to empirical investigations, Self-efficacy, Motivation, and Metacognition have been linked to a student’s achievement. In this paper, a conceptual review on the elements of SRL is offered. It also discusses whether there is a link between the elements of SRL such as Self-efficacy, Motivation, and Metacognition with the performance of Mathematics among secondary students. According to researchers and many educators, the capacity for SRL is essential for academic achievement. It is described as a multifaceted, dynamic process that combines cognitive, motivational, and emotional components. A growing amount of evidence supports the idea that cognitive self-regulation can be taught and that students who employ these abilities tend to do better in the subject area in which they are used. As a result, researchers have started to focus on understanding the elements of SRL. In this paper, the theories will first be highlighted. This will be followed by explanations on emotions and self-efficacy in SRL and then the motivation in SRL will be explicated. The study will address metacognition in SRL and then it will demonstrate on SRL and performance. Additionally, SRL will provide the information on the significance of the study after the discussion.

Objective: The objective of this scoping review is to explore existing literature related to hospital-based HTA in the Latin America and Caribbean regions to examine and map the evidence. Introduction: Hospital-based HTA is a specific context “in” and “for” HTA in hospitals. This context is multidisciplinary, systematic, and evidence-based approach that considers the clinical, economic, and organizational aspects of implementing and utilizing a particular technology in a hospital setting, considering moving the assessment closer to the point of care, where technology's costs, impacts, and benefits can be directly assessed. HB-HTA aims to provide solid and relevant information to support evidence-based decision-making regarding adopting, excluding, and using health technologies in hospitals. HB-HTA programs can yield positive outcomes, enhancing the quality of care and generating substantial financial savings.Inclusion criteria: This scoping review will consider studies addressing hospital-based HTA in Latin America and Caribbean regions related on health technologies used in hospitals. The working definition of hospital-based HTA in this review is a combination approach of clinical, economic, and organizational aspects of implementing and utilizing a particular technology in a hospital setting. Additionally, to mapping and summarizing relevant methodological papers from any international HTA Agency regarding to HB-HTA. Methods: Three databases will be searched for qualitative, quantitative, and mixed methods study designs. The gray literature search will include policy and practice documents from HTA and health organization websites. Two reviewers will independently complete title and abstract screening prior to full-text review and data extraction.
What factors influence uptake of bowel, breast, and cervical cancer screening? Insights from an overview of international research
Authors: Prowse Sarah R , Treweek Shaun , Brazzelli Miriam
Published: August 2023

BackgroundFor cancer screening programmes to be effective in early detection it is important that those invited can access screening services and understand the benefits of participation. A better understanding of the factors that matter to potential participants of cancer screening programmes can assist in developing strategies to increase uptake and may also be relevant in further understanding and resolving population-based inequalities. MethodsWe conducted an overview of systematic reviews to answer the question: What factors influence the uptake of cancer screening services (breast, bowel, and cervical) in high-income countries? A narrative approach supported by tabular summaries and qualitative heat maps was used to categorise factors, described as ‘barriers’ or ‘facilitators’. ResultsA total of 41 systematic reviews met the criteria for inclusion. The barrier with the greatest number of ‘hot spots’ across all three screening programmes was a fear of the unknown regarding a possible diagnosis of cancer or abnormal screening results, followed closely by a general lack of knowledge surrounding cancer screening programmes. The greatest collective facilitator to uptake was recommendation by a healthcare provider to attend screening. ConclusionsAcross all factors ‘trust’ and ‘building trusted relationships’ can be seen as integral to the success of cancer screening programmes and must be reflective of collaborative efforts to mitigate barriers and enhance facilitators to uptake. There is future scope to consider interventions that 1) increase demand for screening services, 2) reduce barriers to uptake of services, and/or 3) are relevant to the healthcare system and those providing services.
Quantifying salinity in heterogeneous coastal aquifers through ERT and IP: insights from laboratory and field investigations

Published: August 2023

The lithological and stratigraphical heterogeneity of coastal aquifers has a great influence on saltwater intrusion (SI). This makes it difficult to predict SI pathways and their persistence in time. In this context, electrical resistivity tomography (ERT) and induced polarization (IP) methods are receiving increasing attention regarding the discrimination between saltwater-bearing and clayey sediments. To simplify the interpretation of ERT data, it is commonly assumed that the bulk conductivity mostly depends on the conductivity of pore-filling fluids, while surface conductivity is generally disregarded in the spatial and temporal variability of the aquifers, particularly, once the aquifer is affected by the presence of saltwater. Quantifying salinities based on a simplified petrophysical relationship can lead to misinterpretation in aquifers constituted by clay-rich sediments. In this study, we rely on co-located data from drilled boreholes to formulate petrophysical relationships between bulk and fluid conductivity for clay-bearing and clay-free sediments. First, the sedimentary samples from the drilled wells were classified according to their particle size distribution and analyzed in the lab using a SIP in controlled salinity conditions to derive their formation factors, surface conductivity and chargeability. Second, the deduced thresholds are applied on the field to distinguish clay-bearing sediments from brackish sandy sediments. The results are validated with logging data and direct salinity measurements on water samples. We applied the approach along the Luy River Catchment and find that the formation factors and surface conductivity of the different unconsolidated sedimentary classifications are varying from 4.0 to 8.9 for coarse-grained sand and clay-bearing mixtures, while normalized chargeability above 1.5 mS/m indicates the presence of clay. The clay-bearing sediments are mostly distributed in discontinuous small lenses. The assumption of homogenous geological media is therefore leading to overestimating SI in the heterogeneous clay-bearing aquifers.
Using computational models of learning to advance cognitive behavioral therapy

Published: August 2023

Many psychotherapy interventions have a large evidence base and can help a substantial number of people with psychiatric symptoms. However, we still have little understanding of why treatments work. Early advances in psychotherapy, such as the development of exposure therapy, built on theoretical and experimental evidence from Pavlovian and instrumental conditioning. More generally, all psychotherapy achieves change through learning. The past 25 years have seen substantial developments in computational models of learning, with increased computational precision and a focus on multiple learning mechanisms and their interaction. Now might be a good time to formalize psychotherapy interventions as computational models of learning to improve our understanding of mechanisms of change in psychotherapy. To advance research and help bring together a new joint field of theory-driven computational psychotherapy, we first review literature on cognitive behavioral therapy (exposure therapy and cognitive restructuring) and introduce computational models of reinforcement learning and representation learning. We then suggest a mapping of these learning algorithms on change processes presumably underlying the effects of exposure therapy and cognitive restructuring. Finally, we outline how the understanding of interventions through the lens of learning algorithms can inform intervention research.

Published: August 2023

Reminiscence-based interventions focus on recalling autobiographical memories and reflective reasoning to develop a healthy and adaptive view of oneself and one’s life. This study aimed to replicate the effects of a three-session, group-based, positive-memory version of cognitive-reminiscence therapy (CRT) on psychological resources and mental well-being and extend the findings to anticipated pleasure. The participants (N=75, Mage= 43.7 (SD= 16.7), 60% females) were randomised to CRT or control group. Anticipated pleasure, psychological resources (schemas of positive self-esteem, self-efficacy, meaning in life, optimism), mental well-being (depression, anxiety, and stress symptoms) and theorised change processes (automatic negative thoughts, awareness of narrative identity) were assessed. Relative to the control group, the CRT group reported significantly higher anticipated pleasure (d=0.76-0.93) and psychological resources of self-esteem, self-efficacy, and optimism (d’s=0.58-0.99) at post-CRT and follow-up, and lower depressive symptoms post-CRT and at follow-up (d=0.56–0.67). Findings on meaning in life and negative automatic thinking were partially replicated. This study replicates findings of the effectiveness of this intervention for improving psychological resources such self-worth, confidence and optimism and depressive symptoms, and indicates additional effects on anticipated pleasure. CRT may serve as a standalone intervention, or as an adjunct ‘memory booster’ for interventions focused on future thinking and related anticipated reward.
Caring for Present and Future Generations Alike: Longtermism and Moral Regard Across Temporal and Social Distance
Authors: Syropoulos Stylianos , Law Kyle Fiore , Young Liane
Published: August 2023

In a comprehensive investigation involving a reanalysis and five pre-registered studies (N = 4,032), we investigate if empirically identified longtermists, determined by their Longtermism Beliefs Scale (LBS) scores, exhibit heightened moral regard for present and future generations across social distances. Longtermists consistently value future generations, present generations, outgroups, and nature more than the general population, as measured by the Moral Expansiveness Scale (MES). They also exhibit reduced dehumanization tendencies towards outgroups and future people, alongside greater identification with their community, compatriots, and all humans. Various factors explain the link between longtermism beliefs and moral regard, with moral obligation and identification with all of humanity potentially mediating it. Notably, the LBS maintains its significant impact on moral regard even when considering other future-oriented factors, highlighting its unique predictive power. These findings offer valuable insights into longtermist ethics, bridging theory and practical implications for safeguarding present and future generations amid existential threats.

Coal mining activities carried out by PT. PQ causes a change in the environmental setting so that its function needs to be restored according to its designation. The return of land function is carried out through reclamation activities. Reclamation activities need to be evaluated in order to continue to make improvements and optimal results. This study assesses the success rate of reclamation carried out by PT. PQ. This study aims to examine and evaluate the reclamation activities carried out by PT. PQ is based on Decree of the Minister of Energy and Mineral Resources Number 1827/30 K/MEM of 2018. The research method used is field observation; analysis of primary and secondary data on land use, revegetation, and maintenance stages; and mathematical calculation of reclamation success rate. Soil quality was tested by testing the pH of H2O, organic C, and total N. The results showed that the soil in the reclamation area is considered to be acidic, namely the pH of H2O is 4.5 -5.5; organic C by 1-2%; N total of 0.1 – 0.2%; C/N of 5 – 1 test for pH H2O, organic C, and N total reclamation success rate of 94.1 or in the good category. The soil in the reclamation area has a pH of 4.3 and a soil organic C content of less than 1%. The main eucalyptus oil plants require soil with a pH of 4.5 -5.5. organic C by 1-2%; N total of 0.1 – 0.2%; C/N of 5 – 1. To complete the reclamation activities, it is necessary to increase the pH of the soil, which is still acidic, namely 4.3 and to increase the organic C content of the soil, which is still low, namely <1%. Findings of acidic soil pH and soil organic C content below the standard needed for the main plant eucalyptus oil are initial information for improving soil conditions in the reclamation area of PT. PQ so that reclamation activities run better.
“There is a better you in you”: Promises and Ideologies of Self-Tracking Technologies
Authors: Dorfmann Max , Menéndez-Blanco María , De Angeli Antonella
Published: August 2023

Self-tracking describes capturing and analysing the body and life using digital technologies. Its popularity is propelled by the widespread availability of enabling technologies like smartwatches or fitness-trackers. However, given the broad consensus on the co-productive relationship between technologies and social realities, reducing this phenomenon to technological feasibility alone would be inappropriate. This paper explores self-tracking by investigating its enculturated meanings, focusing on Western Europe. For this purpose, we analysed promises behind self-tracking technologies articulated in TV-commercials considering their relation to the late-modern socio-material constitution. The findings suggest that self-tracking addresses several ideal-typical late-modern problems, like the contingency of everyday living. Self-tracking technologies promise to counteract these problems by employing number-based rationalisation strategies. They aim to increase and condense performance capacities and activate the users. Thereby, they turn out to be technologies of an instrumental reason attempting to counter collective issues by optimising the individual.

This paper presents preliminary thermal-hydraulics calculation results for a small modular reactor (SMR) with a thermal capacity of 200 MW based on the ACPR50S reactor technology (Advanced customer-friendly practicable reliable 50 MWe compact SMR). The basic parameters and thermal-hydraulics safety were assessed, including the heat coolant flow through the core, fuel, and cladding temperatures to ensure the reactor’s capability to operate within safe limits. The SMR configuration was simulated using the RELAP5 program and performed the calculation in about 500 seconds in the steady state. The coolant temperature of the heat carrier along the height of the core at the inner and outer was found to be different (1.7%) from the reference value. Regarding safety, the departure from nucleate boiling ratio (DNBR) was also estimated along the average channel and the hottest channel of the core in the steady state. The results from this study will be further used in transient computations and incident analysis for SMRs.

Plastic waste pollution is a major environmental issue all over the world, with Vietnam ranking among the ten most polluted countries. As a result, it is critical that research aims to reduce pollution levels from this plastic waste resource through the fabrication and application of biodegradable polymers to replace traditional plastics. In this study, plastics blend film based on cassava starch/poly(butylene adipate-co-terephthalate) (TPS/PBAT) (ratio of 40/60) was fabricated in a reactive twin screw extruder. Testing methods following the ASTM 6400 standard were used to evaluate the biodegradability of the film based on the TPS/PBAT blend shown that under controlled aerobic composting conditions (temperature of 58°C and humidity of 55%), the biodegradation rate of the film, calculated according to the amount of CO2 produced, reached of 91% after 155 days, and the disintegration degree of 96% after 53 days. The rate of bean and cucumber germination on the resulting compost demonstrates satisfactory terrestrial safety. The results of this study confirmed that TPS/PBAT film is a highly compostable material that can be used to improve the biodegradability of products like munch films, supermarket bags, seedling bags, and garbage bags.

Polybrominated diphenyl ethers (PBDEs) are one group of flame retardants used as additives in many household products, in-cluding plastic products. Determining the residues of PBDEs in household plastic products is required to control their effects on human health and leach into the environment after disposal. This study was conducted to optimise sample preparation conditions for analysing PBDEs in plastic waste from household products. The study results are given that the instrument detection and quantification limits (IDL and IQL) ranged from 4.19 to 28.4 ppb and 14.0 to 94.8 ppb, respectively. In addition, the method detec-tion limit (MDL) and method quantification limit (MQL) were the lowest at 2.20 and 7.35 ng/g (BDE 99) and the highest at 24.1 and 80.3 ng/g (BDE 209), respectively, while the recovery val-ues for spiking samples at different concentrations ranged from 89.1 to 104.5%. The results of the method validation can confirm that the soxhlet extraction and solid phase extraction (SPE) tech-niques combined with gas chromatography mass spectrometry (GC/MS) equipment can be applied to determine the PBDEs in plastic waste samples.

Authors: Dolcé Patrick , de Beaumont-Dupont Annie , Jutras Philippe , Mailhot-Léonard Florence , Alexandra Rosca Maria , Aubé-Maurice Joanne
Published: August 2023

Background:

The lower Saint Lawrence river region (LSLRR), in Quebec, has a 10-fold higher incidence of Q fever compared to the provincial rate. This study aimed to review clinical cases and the Q fever risk exposure in this region.

Methods:

Data were retrieved from microbiology laboratory, medical records from Rimouski Regional Hospital and Public Health reports between 1991 and 2018. They were analyzed with Epi Info 7.2.2.6. Patients with confirmed acute, probable acute, and chronic Q fever were classified using standard case definitions and mapped according to the postal code, to assess the correlation between cases and sheep distribution.

Results:

Out of 295 cases, 258 were included (241 confirmed acute, seven probable acute, 10 chronic). Median age was 49 years, 76% were male. For acute cases, the prominent symptoms were fever (99%), headache (83%), chills (80%), sweating (72%), myalgia (69%), and fatigue (67%). Clinical presentation was mostly febrile syndrome with mild hepatitis (84%). A seasonal peak was observed from May to July (56% of acute cases). Most cases (56%) occurred within the two counties where sheep production was highest. Exposure to sheep was prominent 93%, including 64% direct contact (15% shepherds, 49% sheepfold visitors), 14% indirect contact, and 15% sheepfold neighbors.

Conclusions:

To our knowledge, this is one of the largest retrospective studies of Q fever cases reported in Canada. Q fever in Quebec LSLRR is associated mainly with sheep exposure. Fever and hepatitis were the most common manifestations. Preventive measures should be considered in this region to protect sheepfold workers, visitors, and their neighbors.
The Basic Communication Course and College Student Retention: A Longitudinal Analysis
Authors:   Saginaw Valley State University, Schneider David , McCullough Jennifer ,   Saginaw Valley State University
Published: August 2023

This longitudinal study examined the relationship between two formats of the basic communication course (BCC) and first-year college student retention over a four-year period. Chi-square and logistic regression models indicated students who completed the BCC were more likely to be retained than those who did not complete the BCC. While completing the BCC was associated with retention for both formats, the hybrid BCC format was more consistently related to retention than the public speaking BCC. Students from certain demographic groups who completed the hybrid BCC were retained more frequently than students from the same demographic who did not complete the hybrid BCC. Demographics for the public speaking BCC revealed a different retention profile. Implications and future directions concerning the BCC are discussed.

This study aims to determine serum amyloid A (SAA), haptoglobin (Hp), interleukin-1β (IL-1β), interleukin 6 (IL-6) and tumor necrosis factor-α (TNF-α) concentration in cases of Cryptosporidiosis that are frequently encountered in calves in veterinary medicine. Although many experimental studies have been conducted in this field, studies of naturally infected calves are quite a few. In this study, 10 neonatal Holstein calves diagnosed with Cryptosporidium were included. Stool samples were taken from calves with diarrhea using a rapid test kit (BIO-K 313 rapid test kit). Blood samples were obtained from the jugular vein pre- and post-treatment for biochemical measurements. SAA, Hp, IL-1β, IL-6 and TNF-α concentration measurements were conducted with ELISA reader using commercial kits. Calves with Cryptosporidiosis presenting with diarrhea showed a statistical difference in SAA, Hp, IL-1β, IL-6, white blood cell and hemoglobin values before and after treatment, whereas hematocrit, red blood cell and TNF-α concentrations did not show any statistical difference before and after treatment. According to these findings, to follow up the treatment process of calves with Cryptosporidiosis, it is thought that measuring the concentration of SAA, Hp, IL-1β and IL-6 will be useful for determining disease severity, selecting appropriate treatment, following treatment efficacy and determining subclinical diseases.

Authors: Volkov Sergey
Published: August 2023

In March, Center for Russian-African Relations and Foreign Policy of African Countries of the Institute for African Studies (Russian Academy of Sciences) held a conference “Africa – the Rising Center of an Emerging Multipolar World”. The conference took place during a period of sharp aggravation of the international situation, which required for Russia to revise the directions of its foreign policy with the focus on some countries, in particular, the countries of Africa.
The event held in the format of a videoconference was attended by scientists of the IAfr RAS, MGIMO University, RISI, Institute of Economics (Academy of Sciences of Belarus), Research Economic Institute of the Ministry of Economy (Republic of Belarus), teachers and students of Patrice Lumumba RUDN University, Moscow State University, TISBI University of Management (Kazan, Russia), Samara State University of Economics.
The role and place of African countries in the system of international relations and in strategies of the main centers of power, the African policy of the world’s leading players, as well as the state and prospects of Russian- and Belarusian-African cooperation in the context of a sharp aggravation of the international situation and tough economic sanctions imposed by the West on Russia and Belarus were discussed. The speeches contained recommendations on strengthening both countries mutually beneficial partnership with African states, which may be used by government organizations and business community.
Non-tax and tax payments for negative impact on the environment: on the question of models and their stimulating role when integrated into the Russian economy
Authors: Vakula Marina
Published: August 2023

The article is devoted to the issues of legal regulation of payments levied in order to implement the principle of payment for nature management (the so-called “environmental payments”), as well as the analysis of the effectiveness of various models of embedding non-tax and tax fees in the economy of the Russian Federation and foreign countries. The relevance of the study is due to the invariance of approaches used in world practice to the development of state management policy in the field of reducing the negative impact on the environment in general with the use of ecological and economic incentives aimed at ensuring rational use of natural resources in the activities of economic entities, in particular. The purpose of the study is to study the impact of environmental payments on the effectiveness of environmental protection activities and to consider the prospects for the development of their stimulating role in order to ensure rational use of natural resources, as well as to reduce the anthropogenic load on environmental components. The achievement of this goal is ensured through a comparative analysis of the best foreign practices in terms of legal regulation of the implementation of the principles of “polluter pays”, “payment for environmental management”, as well as through the formation of directions for improving Russian legal regulation in this area using a comprehensive economic model combining fiscal, compensatory and incentive functions aimed at improving environmental and economic efficiency environmental policy. Based on the review of trends in the legal regulation of the “polluter pays” principle, the authors conduct a general theoretical characterization of payments for negative environmental impact and propose directions for improving the development of the institute of rational nature management. The article substantiates the conclusion that when choosing an economic model for the implementation of the principle of payment for environmental management and compensation for environmental damage, attention should be focused on stimulating responsible environmental management. This will make it possible to increase the efficiency of managing the environmental and economic activities of economic entities, including through their motivation to transform production processes using low-carbon, energy-efficient and other “green” technologies. In the course of the research, the authors used legal methods of normative legal formalization, comparative jurisprudence, legal modeling, as well as general scientific methods - system analysis, deduction, analogy, synthesis, etc.
Big Data and human rights: toward legal regulation
Authors: Talapina Elvira V.
Published: August 2023

In the absence of a universally accepted definition of Big Data, its attributes are described in the current literature. The Big Data processing is still outside the legal frameworks, so the most significant legal problem is the “contact” with personal data, for which rules have already been established. Any violations in this area directly affect Human Rights, especially the right to privacy. In the case of Big Data, privacy is increasingly seen as an economic right and personal data as having economic value. The need to respect the right to privacy puts the data subject at the center of the legal construction of legal access to personal data who expresses informed consent to operations with his personal data.
In the context of Big Data processing, it is necessary to select a more appropriate and dynamic model of informed consent. Although data as such is unlikely to be a right of property object, it should be protected through other mechanisms, such as those aimed at ensuring accountability. It is the development of accountability mechanisms that is becoming one of the main directions in the Big Data regulation.

AIM: To evaluate the usefulness of handheld ultrasound in comparison with high-end ultrasound for lesion evaluation before and after sclerotherapy in pediatric patients with venous malformations (VMs). MATERIAL AND METHODS: 10 pediatric patients prior to and after sclerotherapy were scanned by an experienced examiner using handheld ultrasound (Vscan AirTM) and high-end ultrasound (LOGIQ E9/E10) as reference. Patients with associated venous thromboses and intralesional aneurysms had been excluded. Results were interpreted independently by two readers in consensus. RESULTS: 10 patients (4-17 years; 10.0±4.32 years; female n = 6, male n = 4) with 10 VMs (4 of the head and neck region, 4 of the upper and 2 of the lower extremities) were examined. 7 phleboliths were detected. The average rating score achieved by the high-end device never was less than 4, by Vscan AirTM never less than 3. An exception was the assessment of AV fistulas. In comparison with the evaluation of variables examined, we found a significant difference between the high-end scanner and the handheld device regarding the achieved image quality. CONCLUSION: Vscan AirTM ultrasound device allows new possibilities for procedure planning and post-procedural control of pediatric patients with VMs.

BACKGROUND: Local ablation is an important treatment for liver cancer in cases of cirrhosis. Liver failure may occur after ablation, especially in advanced liver diseases. Currently, there is no standardization for peri-interventional risk assessment. The liver maximum capacity test (LiMAx) is used to assess functional liver capacity, but there is a lack of exploration of its use in this context. OBJECTIVE: The aim of this study was to retrospectively evaluate the usefulness of peri-interventional LiMAx measurements in patients with primary or secondary liver cancer who underwent ablation treatment. METHODS: A LiMAx test was performed at 24 hours pre- and postablation in 49 patients. Blood parameters were collected to determine liver function using MELD and ALBI scores. The results of the LiMAx test were related with these scores and to critical postintervention LiMAx values. RESULTS: LiMAx values correlated strongly with MELD and ALBI scores before the intervention and reflected the change in liver function, as shown by an increase in scores after the intervention. Notably, LiMAx values decreased during the intervention. AUC analysis for patients at risk of reaching a critical liver level after the intervention showed a cutoff value of 186μg/kg/h. CONCLUSIONS: The LiMAx test may be a valuable tool in liver ablation for both peri-interventional monitoring of liver function and preintervention risk assessment.
