Published: March 2022

Purpose: Multicriteria methods have gained traction in both academia and industry practices for effective decision-making over the years. This bibliometric study aims to explore and provide an overview of research carried out on multicriteria methods, in its various aspects, over the past forty-four years.
Design/Methodology/Approach: The Web of Science (WoS) and Scopus databases were searched for publications from January 1945 to April 29, 2021, on multicriteria methods in titles, abstracts, and keywords. The bibliographic data were analyzed using the R bibliometrix package.
Findings: This bibliometric study asserts that 29,050 authors have produced 20,861 documents on the theme of multicriteria methods in 131 countries in the last forty-four years. Scientific production in this area grows at a rate of 13.88 per year. China is the leading country in publications with 14.14%; India with 10.76%; and Iran with 8.09%. Islamic Azad University leads others with 504 publications, followed by the Vilnius Gediminas Technical University with 456 and the National Institute of Technology with 336. As for journals, Expert Systems With Applications; Sustainability; and Journal of Cleaner Production are the leading journals, which account for more than 4.67% of all indexed literature. Furthermore, Zavadskas E. and Wang J have the highest publications in the multicriteria methods domain regarding the authors. Regarding the most commonly used multicriteria decision-making methods, AHP is the most favored approach among the ten countries with the most publications in this research area, followed by TOPSIS, VIKOR, PROMETHEE, and ANP.
Practical implications: The bibliometric literature review method allows the researchers to explore the multicriteria research area more extensively than the traditional literature review method. It enables a large dataset of bibliographic records to be systematically analyzed through statistical measures, yielding informative insights.
Originality/value: The usefulness of this bibliometric study is summed in presenting an overview of the topic of the multicriteria methods during the previous forty-four years, allowing other academics to use this research as a starting point for their research.
Compressibility and shear strength of a tropical fibrous peat
Authors: Li Z.-S. , Rahayu W. , Souli H. , Soepandji B. S. , Fleureau J.-M.
Published: March 2022

This study examines the compressibility and shear strength of an Indonesian fibrous peat through oedometric and consolidated undrained (CU) triaxial tests. The influence of fibres is considered by preparing two series of specimens – undisturbed and reconstituted. For the latter, the coarse fibres larger than 80 μm were removed by wet sieving. Oedometric test results show that, as the coarse fibres are removed, (a) the secondary consolidation (log t, ε1) curves change from concave-down to linear and (b) the compression index of the oedometric (log σv, e) curves becomes smaller. These observations agree well with previous results on peats from polar and temperate zones. In CU triaxial tests, the undisturbed specimens fail to show strain hardening behaviour in the (ε1, q) diagram. Their effective friction angle (37·5°) is smaller than the typical values for other fibrous peats (40–60°). By comparing the shear strengths reached at different void ratios for both undisturbed and reconstituted specimens, it was found that the presence of structure adds additional shear strength in undisturbed specimens. With a smaller density, the undisturbed specimens reach the same peak deviator stress (e.g. 100 kPa) as the much denser reconstituted specimens.
A practical two-parameter model of pile–soil gapping for prediction of monopile offshore wind turbine dynamics
Authors: Williams Stephen A. , Pelecanos Loizos , Darby Antony P.
Published: March 2022

Monopile mounted offshore wind turbines (OWTs) are expected to experience a very large number of cyclic loads throughout their operational lifetime, and the existing p–y method of foundation modelling does not fully account for the effects of dynamic cyclic loading, such as pile–soil gapping. In this paper a dynamic model based on the beam on non-linear Winkler foundation scheme with a novel algorithm capable of capturing the effects of pile–soil gapping is presented. It can account for gap cave-in, and the resulting gap size can react dynamically to changing loading amplitudes, using only two calibration parameters. Static and dynamic cyclic loaded model validations are presented, and give very good agreement with experimental results, performing better than existing p–y curves for dynamic loading. The model is also applied to an OWT case study and predictions of natural frequency reduction due to soil erosion agree well with measured results. It is shown that the inclusion of gapping may result in a significant decrease to the natural frequency prediction of OWTs relative to the value predicted without gapping. As such, not to consider gapping could lead to unconservative predictions, and any additional soil degradation throughout the serviceable lifetime could therefore result in unwanted resonance. The method provided in this paper provides a simple and accurate model to predict this behaviour which is crucial to ascertain during the design phase.
Cost Barriers to More Widespread Use of Peritoneal Dialysis in the United States
Authors: Baerman Elliot A. , Kaplan Jennifer , Shen Jenny I. , Winkelmayer Wolfgang C. , Erickson Kevin F.
Published: March 2022

The United States Department of Health and Human Services launched the Advancing American Kidney Health Initiative in 2019, which included a goal of transforming dialysis care from an in-center to a largely home-based dialysis program. A substantial motivator for this transition is the potential to reduce costs of ESKD care with peritoneal dialysis. Studies demonstrating that peritoneal dialysis is less costly than in-center hemodialysis have often focused on the perspective of the payer, whereas less consideration has been given to the costs of those who are more directly involved in treatment decision making, including patients, caregivers, physicians, and dialysis facilities. We review comparisons of peritoneal dialysis and in-center hemodialysis costs, focusing on costs incurred by the people and organizations making decisions about dialysis modality, to highlight the financial barriers toward increased adoption of peritoneal dialysis. We specifically address misaligned economic incentives, underappreciated costs for key stakeholders involved in peritoneal dialysis delivery, differences in provider costs, and transition costs. We conclude by offering policy suggestions that include improving data collection to better understand costs in peritoneal dialysis, and sharing potential savings among all stakeholders, to incentivize a transition to peritoneal dialysis.

Extraction and selection of high-molecular-weight DNA for long-read sequencing from Chlamydomonas reinhardtii v1
Authors: Chaux-Jukic Frédéric , Agier Nicolas , Eberhard Stephan , Xu Zhou
Published: March 2022

Recent advances in long-read sequencing technologies have enabled the complete assembly of eukaryotic genomes from telomere to telomere by allowing repeated regions to be fully sequenced and assembled, thus filling the gaps left by previous short-read sequencing methods. Furthermore, long-read sequencing can also help characterizing structural variants, with applications in the fields of genome evolution or cancer genomics. For many organisms, the main bottleneck is to develop robust methods to obtain high-molecular-weight (HMW) DNA for whole genome sequencing purposes. We developed an optimized protocol to extract DNA suitable for long-read sequencing from the unicellular green alga Chlamydomonas reinhardtii, based on CTAB/phenol extraction followed by a size selection step for long DNA molecules. We provide validation results for the extraction protocol, as well as statistics obtained with Oxford Nanopore Technologies sequencing.

Plant assemble - Plant de novo genome assembly: quality assessment v2
Authors: Ferguson Scott , Jones Ashley , Borevitz Justin
Published: March 2022

With the advancement of long-read sequencing technologies and associated bioinformatics tools, it has now become possible to de novo assemble complex plant genomes with unrivalled contiguity, completeness and correctness. As read lengths can surpass repeat lengths, the ability to assemble genomes de novo has dramatically improved, whereby complex plant genomes of widely variable sizes and repeat content have highly benefited. Despite these improvements, challenges remain in performing de novo assembly, namely in developing a reliable workflow and in tool choice. Here we present a protocol collection of bioinformatic workflows detailing plant genome assembly using Oxford Nanopore Technologies long-reads with a de novo assembler (Canu), syntenic or Hi-C scaffolding, and RNA and/or gene homology-based annotation. We have developed and tested these protocols on multiple plant genomes. Using these protocols with sufficient coverage of long-reads, a highly contiguous, complete, and correct plant genome can be assembled. These genomes can further genomic research into structural variation among groups, and SNP genotyping and association studies among populations.

When Politicians Meet Experts: Disinformation on Twitter About Covid-19 Vaccination
Authors: Pérez-Curiel Concha , Rúas-Araújo José , Rivas-de-Roca Rubén
Published: March 2022

The Covid-19 vaccination has meant a huge challenge for crisis communication. After months of lockdowns, mass vaccination was a silver lining moment, but it was under threat from disinformation boosted by misinformation on social media. This research explores how opinion leaders among political leaders and health experts used Twitter to create and manage messages about the vaccination process. Specifically, we show the issues (issue frame) and strategies (game frame) applied by these actors. This study employs a corpus on the words “Covid-19” and “vaccines” used on Twitter by the heads of government and 10 recognized health experts (two for each country) in the US, the UK, France, Portugal, and Spain. We also analyze the accounts of fact-checking projects on those countries (@PolitiFact, @FullFact, @decodeurs, @JornalPoligrafo, and @maldita). The sample allows the comparison of countries with different political cultures that participated differently in the production of vaccines. The data were captured from the beginning of the vaccination drive (December 14th, 2020) until most of the population above 60 were vaccinated (May 14th, 2021). A manual content analysis was performed on the tweets (n = 2,607). The results illustrate that the politicians mostly disagreed with experts regarding issues and strategies. This finding can foster distrust in the elites and, therefore, threatens the long-term success of a public health campaign. Our study contributes to discussions on the role of networks for social cohesion, arguing that the public conversation on Twitter about the vaccination has revealed high levels of controversy.
Effects of Orthodontic Functional Appliances in Relation to Skeletal Maturation of Cervical Vertebrae In Class II Malocclusion
Authors: Guinot Francisco , Ferrer Marina , Díaz-González Lara , García Cristina , Maura Isabel
Published: March 2022

Aim: To evaluate the effects produced by functional orthodontic appliances at dental and skeletal level in relation to the level of skeletal maturation in class II patients

Study design: Longitudinal and observational study

Patients selected for the study had been wearing Sander Bite Jumping Appliance (SBJA) for at least 12 months; they were first diagnosed (T1) with skeletal class II according to Ricketts’ cephalometric analysis, and had had lateral cephalograms taken before and after orthopaedic treatment (T2). Variables studied at T1 and T2 were: facial convexity, inclination of the upper and lower incisors, and facial depth. Results were compared between T1 and T2 for each variable and in relation to cervical maturation stage (CVS) according to the Lamparski analysis. Statistical analysis was performed using Shapiro–Wilk, t-student, Analysis of Variance (ANOVA) and multiple comparison tests, taking as statistically significant a p-value <0.05.

Results: A final sample of 235 patients was obtained. Statistically significant differences were found in the inclination of the mandibular incisors between T1 and T2 and among the different cervical stages when the functional appliances were placed in CVS1 (p = 0.000), CVS2 (p = 0.04) or CVS5 (p = 0.048). For the remaining variables, significant differences were also found between T1 and T2, but these differences were similar in all cervical stages.

Conclusions: A significant proclination of the mandibular incisors was found when the functional appliance was placed during CVS1, CVS2, or CVS5. Time of placement of the functional appliances was not statistically significant for the remaining variables studied.
Relations Developing in Enforcement Proceedings and the Subject of Civil Procedural Law
Authors: Kazijanova S. S.
Published: March 2022

The article considers the issue whether the relations developing in enforcement proceedings are included in the subject of civil procedural law. The important practical importance of the correct deﬁnition of the subject of the industry is indicated. The views of Professor A. K. Sergun on the nature of relations arising in connection with the enforcement of acts of jurisdictional bodies are considered. The author agrees with the position that the enforcement of court decisions is the ﬁnal stage of civil proceedings, and the relations arising in enforcement proceedings are regulated by the branch of civil procedural law. A critical assessment is given to the arguments of supporters of the separation of relations arising from the compulsory execution of acts of jurisdictional bodies from the subject of civil procedural law. It is concluded that heterogeneous social relations can be united in the subject of the industry if it is practically justiﬁed by the need existing in society for their qualitatively peculiar, built on uniform principles of regulatory regulation.
«I can not Compromise on Principles»
Authors: Voronov A. F.
Published: March 2022

In the article, the author analyzes the evolution of the principles of the Russian civil procedure in recent times. It is stated that many provisions of procedural legislation that were considered principles have now lost their signiﬁcance, have changed or are missing. This may mean a qualitative change in the process, in many ways the loss of its essence. This is especially evident in the example of writ proceedings. Unlike some scientists, the author considers this type of proceedings in fact to be legal proceedings and justice, demonstrating the result of disregard for the principles of justice, degradation of the rules of court proceedings. The author discusses how the legal community can convey their concerns about this to the legislator. The author expresses hope for the restoration of the signiﬁcance of the principles of the process. Hope is based on the idea of the cyclical evolution of principles and on healthy conservatism as a direction in politics.
About Legal Policy in the Field of Formation and Implementation Online Dispute Resolution Mechanisms in Civil and Administrative Court Proceedings
Authors: Afanasiev S. F.
Published: March 2022

The article analyzes the legal policy of the countries of the Council of Europe in the ﬁeld of the formation and subsequent implementation of new mechanisms for online dispute resolution in civil and administrative proceedings. In this regard, the guidelines for the use of such mechanisms (which are set out in the relevant Recommendations of the Committee of Ministers of the Council of Europe) are discussed in detail in the ﬁeld of access to justice, equality of arms, evidence and evidence, trial and informed decision, as well as the right to review it. ... Attention is focused on the need to ensure the compatibility of such mechanisms with the key principles of a fair trial and eﬀective remedies set out in the case law of the European Court of Human Rights, including the principles of publicity, transparency, directness, oral hearing and equality of persons involved in a case.

A separate place is given to the problem of using online dispute resolution mechanisms in Russian civil and administrative proceedings. It is noted that today the domestic legislator, as part of the development of its own legal policy agenda, increasingly integrates innovative digital communication methods into the activities of the subjects of procedural legal relations. In particular, in the near future, along with video conferencing, the legislator will allow courts of general and arbitration jurisdiction to use web conferencing as an authentic technology for organizing online meetings and collaboration in real time via the Internet. All this creates a fertile ground for borrowing the positive world experience of introducing the latest mechanisms for online resolution of civil and administrative cases by the justice authorities, taking into account the inviolability of high standards of a fair trial.

Resumo Tendo em vista reclamações de vários professores de Física do Ensino Médio que a grande maioria de seus alunos não compreendem cálculos de Matemática básica, que envolvem a disciplina que ministram, objetivou-se no presente artigo detectar tais dificuldades matemáticas, que mais tarde poderão desencadear em percalços na compreensão de conceitos das disciplinas de Física. Visando esse fim, o artigo mostra o desempenho obtido por 184 alunos do primeiro ano do Ensino Médio em um teste de sondagem matemática de Ensino Fundamental, constituído por 17 questões abertas, aplicado a sete cursos técnicos integrados de nível médio de uma escola pública federal na cidade de Cuiabá no primeiro dia de aula desses estudantes. O teste abordava conceitos aritméticos e geométricos muito importantes para as disciplinas de Física, que compõem a grade curricular dos cursos da escola. Observou-se que cerca de 84% dos que realizaram o teste acertaram menos da metade das questões e que aproximadamente 52,8% deles acertaram entre zero e três questões. Teve pior desempenho na sondagem o curso de Agrimensura, enquanto o melhor desempenho ocorreu no curso de Eletrônica. Vale ressaltar que o resultado aqui obtido na rainha das ciências não deve ser uma particularidade desta instituição específica, mas sim um reflexo conjuntural e, portanto, não se restringe a esta última.

Published: March 2022

This observational study verified the effects of monochromatic lighting for three monochromatic light spectra on the production and quality of laying hen eggs and blood parameters, as probable indicators of environmental stress. Lohmann®29-week-old birds were divided into groups of 20 animals, housed in three experimental houses with different lighting treatments (blue, green and red), and monitored for 90 days. Were analysed 4,443 eggs, and the values of the following measurements were extracted: egg weight (g), albumen height (mm), shell resistance (kgf/cm²), shell thickness (mm), Haugh unit, specific gravity (g/cm³), and egg shape. Blood samples were collected from the birds at the beginning and at the end of the study period. The levels of total plasma protein and the heterophile/lymphocyte ratio remained within the normal range. Laying hens housed under blue and red lighting had higher egg production (per hen) and showed better egg quality results. Red lighting stood out for providing significantly better shell resistance than other treatments. Glucose differed between treatments, with a drop in blood glucose levels as the environment light wavelength increased. The quality of the eggs was affected differently by the sources of monochromatic lighting. Correct lighting management promotes better health for birds and increased egg production and quality.

Authors: Sun Mengxuan , Zhao Jinglin , Shang Heidan
Published: March 2022

The implementation of the smart grid will greatly improve the efficiency of energy supply by detecting, predicting, and reacting to real-time local changes of energy uses. To this end, energy usage prediction of household buildings is critically important to facilitate the implementation of smart grid. This study used a single house as a prototype, employed different observed features, advanced data analysis approach, and artificial neural network model to predict real-time dynamics of house energy usage. Data analysis revealed that among the 26 observed features, only the top ten most important features were helpful and could maximize the neural network model performance. The resultant model has the great predictive capability on energy usage, thus provided a promising framework to improve the smart grid implementation.
Experimental Study of Spectrum Sensing Based on Energy Detection Using USRP
Authors: Shehady Mahmoud H. , Beydoun Ali , Bazzi Oussama
Published: March 2022

Lack of unallocated spectrum and increasing demand for bandwidth in future wireless networks is forcing new devices and technologies to share frequency bands. Cognitive Radio (CR) is a key technology allowing users to benefit from the unused licensed spectrum to increase their bandwidth. One of the main challenges to achieve this concept is the spectrum sensing in order to detect unallocated bandwidths. Energy detector is known for its simplicity in hardware implementation with moderate performances compared to other methods in the literature. This paper presents an implementation of the energy detector based on the calculation of the energy in the time-domain and in the frequency-domain. Both methods were first simulated using Matlab and then implemented and tested in real environment using NI-USRP 2901. Implementation results show a good agreement with the simulation results.
Muscle Synergies Based Gait Phase Classification during Kinematically Constrained Walking on Slackline
Authors: Ullah Safi , Iqbal Kamran , Singh Rajat Emanuel
Published: March 2022

The study aims to develop an state estimation framework for the detection of stance and swing phases of gait cycle during walking on a perturbed platform, i.e. a slackline. We use Support Vector Machine (SVM) classifier for the detection of stance and swing phase in gait cycle. Surface Electromyography (EMG) data was recorded from nine different muscles in the lower extremity from five healthy subjects. The proposed structure utilizes the hypothesis of Muscle Synergies (MS) where the movement intent is modelled as hidden state of the state space framework. We employ time domain modeling of the neural drive that excites the task-dependent muscles. To cater for the naturally existing physiological bounds (the non-negative muscle activations), the state estimation process is executed using a constrained form of the Kalman filter. Principal Component Analysis (PCA) is used for dimensional reduction of reconstructed EMG signal. We evaluated performance of SVM classifier, and the detection accuracy was later enhanced with post processing. Our preliminary experimental results demonstrate a reconstruction and classification accuracy greater than 95%.

Published: March 2022

Fluid, both gas and liquid, is a widely used substance which can be used in pneumatic and hydraulic system. However, the pneumatic system with compressed air system integrated has a flaw that leakage air during power transmission cost a lot of loss both resources and performance. Leak detection is one of the main solution to plug the flaw. In this research, we use acoustic signal to detect the leakage by using it as an input for model. Artificial Neural Network (ANN) is used in our model to achieve deep learning property via Tensorflow. Acoustic signal is recorded in different situation and is used as a model input. So, our model can be trained with leak data and predict the leakage in pneumatic system. We evaluate model using test data and shows the leakage prediction in probability distribution.
Type of Gold Deposit in Arinem Cisewu and Its Surrounding Garut Regency, West Java, Indonesia
Authors: Purwanto Heru Sigit , Kusumayudha Sari Bahagiarti
Published: March 2022

Gold deposit based on the mineralization of gold and other ore minerals in Arinem area and its surrounding was found in the quartz vein. The research area is in Arinem area and its surrounding, Garut Regency, West Java. Arinem and the vicinity was the location for early stage of research program of mineralization in Papandayan area. This area has good mineralization, and according to previous studies, is a low sulfidation area with the presence of pyrite, chalcopyrite, galena and sphalerite (Antam, 2014). The presence of galena and sphalerite mineral has suggested that instead of low sulfidation, the area may be in intermediate sulfidation zone state supported by other data such as quartz breccia, banded quartz and shear as control structure. Lithology in the area consists of breccia Quaternary and lava unit of Jampang formation in Miocene and unit of andesite and basaltic in Quaternary and intrusion of dacite, andesite and diorite. The alteration and mineralization of research area was classified as propylitic alteration zone with the presence of chlorite, epidote and calcite mineral, argillic alteration zone with montmorillonite, kaolinite mineral, silicic alteration zone with the presence of quartz-sericite, a bit of calcite mineral. The observed ore minerals are pyrite, chalcopyrite, galena, sphalerite. The geological structure was controlled by horizontal fault in almost north-south direction of N 170O-180O E and northeast – southwest horizontal fault in N 40O – 50O E, while the mineralization zone was controlled or following fault pattern of N 170O - 175O E.

A Review on EMG Signal Classification and Applications
Authors: Ting Evon Lim Wan , Chai Almon , Chin Lim Phei
Published: March 2022

Electromyography (EMG) signals are muscles signals that enable the identification of human movements without the need of complex human kinematics calculations. Researchers prefer EMG signals as input signals to control prosthetic arms and exoskeleton robots. However, the proper algorithm to classify human movements from raw EMG signals has been an interesting and challenging topic to researchers. Various studies have been carried out to produce EMG-based human movement classification that gives high accuracy and high reliability. In this paper, the methods used in EMG signal acquisition and processing are reviewed. The different types of feature extraction techniques preferred by researchers are also discussed, including some combination and comparison of feature extraction techniques. This paper also reviews the different types of classifiers favored by researchers to recognize human movements based on EMG signals. The current applications of EMG signals are also reviewed.
Regularized Block Diagonalization Precoding Transmission Scheme Using Relay in NOMA

Published: March 2022

In Multiuser Multiple Input Multiple Output (MU-MIMO) system, Block Diagonalization (BD) and Regularized Block Diagonalization (RBD) are schemes which completely suppress Inter-User Interference (IUI). BD and RBD use the same number of RF chains and transmit antennas as the number of data streams in general. This paper proposes a RBD precoding transmission scheme using relay in Non-orthogonal Multiple Access (NOMA) system to reduce complexity of transmitter structure. The proposed scheme uses only half the number of RF chains and transmit antennas compared to the conventional RBD scheme. The number of Singular Value Decomposition (SVD) of the proposed scheme is also reduced compared to the conventional RBD, while Successive Interference Cancellation (SIC) is needed additionally. However, the proposed algorithm can achieve low computational complexity since SIC is simpler than SVD. However, the proposed scheme has poor BER performance compared to the conventional RBD. Therefore, further study is needed to increase the BER performance while the complexity is reduced.
Parallel Matching Pursuit Algorithm to Decomposition of Heart Sound Using Gabor Dictionaries
Authors: Nieblas Carlos I.
Published: March 2022

In order to improve the performance of matching pursuit algorithm, we propose a Parallel Matching Pursuit algorithm to decompose phonocardiogram sounds of long duration. The main goal is to demonstrate the performance of the Parallel Matching Pursuit algorithm (PMP) compared with traditional iterative matching pursuit algorithm to decompose normal and pathological heart sounds of Phonocardiogram (PCG) using a Gabor dictionary. This architecture is implemented in open source Java SE 8 using a concurrency library, which is able to reduce computational cost using multi-threading until 83 % compared with traditional Matching Pursuit. Java language is widely used in the creation of web components and enterprise solutions so based on this point the main idea of this research is to set the base to implement Parallel Matching Pursuit algorithm (PMP) on web platforms focused on the monitoring of heart to sounds. This implementation allows exploring and applying iterative algorithms or sparse approximation which require processing long audio signals with low processing time.
Pandemic-prone: how has COVID-19 affected the homeless population?
Authors: Mistry Neel
Published: March 2022

Homelessness refers to the lack of stable, permanent, and appropriate housing, exacerbated by factors such as low income or chronic illness. Homeless shelters serve as vectors of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission, given shared living spaces and lack of access to healthcare resources. Individuals experiencing homelessness are not only at greater risk of COVID-19, but they also have various underlying social and health adversities. This paper explores the unique effects of COVID-19 on individuals experiencing homelessness, the underlying risk factors, and changes that can be implemented to mitigate these challenges.
Sudden Stops in Latin America and the Caribbean during COVID-19

Published: March 2022

External capital accounts suffered during the COVID-19 crisis in Latin America and the Caribbean, but perhaps surprisingly the impacts were less severe than in previous crises. Gross capital inflows offset the outflows of residents, in sharp contrast to the global financial crisis of 2008/09 when residents repatriation of capital countered withdrawals from non-residents. In general, the result was relatively stable net capital inflows and modest current account adjustments. Still, some countries that had seen inflows fall prior to the crisis, reflecting weaker fundamentals, suffered Sudden Stops in net capital flows. Given accommodating global monetary policy, sound fundamentals ensured access to liquid international capital markets, reducing the impacts of Sudden Stops during the pandemic.
Coping with Stress and Burnout in the Physical Education Teaching Profession
Authors: Brudnik-Dąbrowska Maria , Noworol Czesław
Published: March 2022

The article describes a study of coping strategies of Physical Education (PE) teachers and their role in the process of burning out. It highlights the role of gender differences in coping strategies.

Female PE teachers apply mostly coping strategies like Fighting, Social support, wishful thinking, alleviation of outcomes, and Assuming responsibility, actions following the plan. They use the least likely Distancing.

Male PE teachers frequently use the strategies Concentration on the task, actions following the plan, and Fighting. Successively, they use Accepting responsibility, and the least likely Reduction of tension.

Some strategies derived in the research effectively cope with burnout in the PE teaching occupation and others are ineffective and may even lead to a depersonalized treatment of students.

Value for Money of Social Assistance in Fragile Contexts: Considerations, Evidence, and Research Priorities
Authors: Wylde Emily
Published: March 2022

Value for Money (VfM) is an essential tool for balancing difficult policy and programme decisions. While many of the conceptual approaches to VfM and methods for estimation are similar between regular development programming for social protection and humanitarian cash and food assistance, so far these literatures have evolved in fairly distinct silos. There is relatively little work that brings the two strands together. This thematic review provides a conceptual framework for understanding VfM of social assistance in fragile and conflict-affected situations (FCAS). It draws out what is particular to these contexts and identifies key areas for focus. It then reviews the existing literature to identify gaps and point to priorities for further research.
