Contextualization: M. scabrella is a native tree species of the Brazilian Mixed Ombrophilous Forest, with a high ecological importance and economic potential.
Knowledge gap:   There is a lack of information about the use of resources that favour the seedlings production of this species.
Purpose: This study aimed to determine the most appropriate doses of controlled-release fertilizer (CRF) combined with the addition of remineralizer for production of M. scabrella seedlings.
Methodology: Seedlings were produced using four doses of CRF (0, 4, 8, and 12 kg m-3) and four doses of remineralizer (0 %, 10 %, 20 %, and 30 %), in a 4 x 4 factorial scheme. At 180 days of seedling production, growth in height and stem diameter, shoot (SDB), root (RDB) and total biomass (TDB), and Dickson quality index (DQI) were evaluated.
Results and conclusions: The use of remineralizer provided an increase in density and water retention capacity of substrates, as well as a reduction of macroporosity and total porosity. Combined with doses of 4 and 8 kg m-3, CRF contributed to the increase of biomass and DQI. The addition of 10 % remineralizer, associated with 4.0 kg m-3 CRF, provides adequate growth to produce M. scabrella seedlings. Above this percentage of remineralizer and CRF dose, species growth rate is reduced.

Authors: Munar Samboní Andrés Mauricio , Rodríguez Carlosama Adalberto , Muñoz España Jorge Luis
Published: January 2022

Contextualización: El cambio climático y las actividades antrópicas sobre los recursos naturales se constituyen como los principales causantes de la pérdida de biodiversidad y la redistribución de las especies. 
Vacío de conocimiento: Sin embargo, los efectos a nivel de comunidades y ecosistemas, así como los impactos en cultivos agrícolas en escala regional, son poco estudiados.  Los modelos de distribución de especies se han convertido, por lo tanto, en valiosas herramientas para la predicción de áreas potencialmente aptas para especies cultivables, su gestión y planificación.
Propósito: Este estudio consistió en la predicción de potenciales áreas cultivables de maracuyá (Passiflora edulis var. flavicarpa Degener), granadilla (Passiflora ligularis Juss), y cholupa (Passiflora maliformis L.) en una región tropical, a través del modelo MaxEnt, en escenarios de cambio climático. 
Metodología:  Se utilizaron como datos de entrada (para el modelo MaxEnt) registros de presencia de las especies analizadas, obtenidos a partir de sus coordenadas geográficas. En total, fueron usados 141 registros de presencia de maracuyá, 256 registros de granadilla y 40 registros de cholupa, así como 12 variables bioclimáticas para las proyecciones actuales y futuras en los periodos 2050 y 2070, considerando así dos escenarios RCPs (Representative Concentration Pathways) del Coupled Model Intercomparison Project (CMIP5) (RCP 4.5 y RCP 8.5).
Resultados y conclusiones: Los resultados revelan que las potenciales áreas cultivables para las especies analizadas podrían pronosticarse a través de MaxEnt utilizando registros de presencia en campo y variables bioclimáticas. Así mismo, las simulaciones indicaron que las áreas de ocurrencia potencial para las especies analizadas podrían disminuir en el futuro dependiendo de los escenarios climáticos (RCP 4.5 y RCP 8.5) para los periodos 2050 y 2070. Para los cultivos de maracuyá, granadilla y cholupa, las mayores reducciones en las áreas de ocurrencia potencial corresponden al 23 %, 25 % y 31 % respectivamente, y se presentarían en el período 2070 en un escenario pesimista (RCP 8.5). Este es el primer estudio que pronostica las potenciales áreas cultivables de pasifloras utilizando el modelo Maxent y escenarios de cambio climático en escala regional en una región tropical. El abordaje propuesto puede proveer importantes herramientas para la gestión y aprovechamiento sostenible de las especies estudiadas.
Bait-ER: a Bayesian method to detect targets of selection in Evolve-and-Resequence experiments
Authors: Barata Carolina , Borges Rui , Kosiol Carolin
Published: January 2022

For over a decade, experimental evolution has been combined with
high-throughput sequencing techniques in so-called Evolve-and-Resequence
(E&R) experiments. This allows testing for selection in populations
kept in the laboratory under given experimental conditions. However,
identifying signatures of adaptation in E&R datasets is far from
trivial, and it is still necessary to develop more efficient and
statistically sound methods for detecting selection in genome-wide data.
Here, we present Bait-ER - a fully Bayesian approach based on the Moran
model of allele evolution to estimate selection coefficients from E&R
experiments. The model has overlapping generations, a feature that
describes several experimental designs found in the literature. We
tested our method under several different demographic and experimental
conditions to assess its accuracy and precision, and it performs well in
most scenarios. However, some care must be taken when analysing specific
allele trajectories, particularly those where drift largely dominates
and starting frequencies are low. We compare our method with other
available software and report that ours has generally high accuracy even
for very difficult trajectories. Furthermore, our approach avoids the
computational burden of simulating an empirical null distribution,
outperforming available software in terms of computational time and
facilitating its use on genome-wide data. We implemented and released
our method in a new open-source software package that can be accessed at
https://github.com/mrborges23/Bait-ER.
Labour Market Flexibility in the Context of the Shadow Economy for the Construction Industry
Authors: Buszko Andrzej
Published: January 2022

The article analyses labour market flexibility in the context of the shadow economy. The main research problem is devoted to the flexibility of the construction labour market in relation to the level of labourers who work in a country's shadow economy. The following hypothesis was adopted: Flexibility of the labour market for the construction industry decreases with an increase in the level of the shadow economy. The MIMIC approach was used to calculate the level of the shadow economy in a group of selected countries, divided into three categories. The first category includes countries with a relatively low level of shadow economy (less than 15% of their GDP). The second group contains a level starting from 15 to 25% of their GDP, while the third group has a shadow economy that exceeds 25% of GDP. The Pearson correlation index was applied in order to measure the coefficient level between market flexibility and the size of the shadow economy. The flexibility of the labour market was calculated as the change of unemployment caused by the change of construction industry output. The research proved that the correlation between market flexibility and the shadow economy is significant. This is due to the fact that the Pearson index reached the level of 0.866, which means that whenever the shadow economy increases, the labour market flexibility of the construction industry decreases.

Theoretical and Practical Guidance for Incorporating Auditor-Client Communication in Experimental Research
Authors: Hatfield Richard C. , Saiewitz Aaron
Published: January 2022

In this paper, we provide theoretical and practical guidance on experimental design choices when incorporating auditor-client communication in audit research. We structure our discussion around Social Presence Theory, noting how elements of social presence impact theoretical predictions and the related experimental design. We then compare non-interactive, highly controlled paper/computer-based studies with studies that involve automated interaction, interaction with an actor, or interaction between participants. We provide a discussion of best practices and pitfalls related to these different experimental design choices, including theoretical and logistical considerations, as well as recent innovations in this area. While our methodological discussion is nested in auditor-client communication research, these methods and logistical considerations are applicable to most accounting experiments designed to address research questions steeped in social psychology (i.e., contexts of human interaction).
Aging Leukocytes and the Inflammatory Microenvironment of the Adipose Tissue
Authors: Dahlquist Korbyn J.V. , Camell Christina D.
Published: January 2022

Age-related immunosenescence, defined as an increase in inflammaging and the decline of the immune system, leads to tissue dysfunction and increased risk for metabolic disease. The elderly population is expanding, leading to a heightened need for therapeutics to improve health span. With age, many alterations of the immune system are observed, including shifts in the tissue-resident immune cells, increased expression of inflammatory factors, and the accumulation of senescent cells, all of which are responsible for a chronic inflammatory loop. Adipose tissue and the immune cell activation within are of particular interest for their well-known roles in metabolic disease. Recent literature reveals that adipose tissue is an organ in which signs of initial aging occur, including immune cell activation. Aged adipose tissue reveals changes in many innate and adaptive immune cell subsets, revealing a complex interaction that contributes to inflammation, increased senescence, impaired catecholamine-induced lipolysis, and impaired insulin sensitivity. Here, we will describe current knowledge surrounding age-related changes in immune cells while relating those findings to recent discoveries regarding immune cells in aged adipose tissue.

Published: January 2022

ABX3 compounds with perovskite structure have been intensively and extensively studied in the last decades in view of their structural richness and amazing variety of interesting properties, such as piezoelectricity, ferroelectricity, ferromagnetism, superconductivity, magnetoresistance, multiferroicity, etc. In this chapter, we recompile well-established chemical and structural concepts in pure inorganic perovskites (mainly oxidic perovskites), and extend them to the young family of hybrid organic-inorganic perovskites. Our final goal is to help understanding the relationships among composition, crystal structure and properties in this new family of compounds, for inspiring further the design of novel materials.
Naturally Layered Aurivillius Phases: Flexible Scaffolds for the Design of Multiferroic Materials
Authors: Halpin J. , Keeney L.
Published: January 2022

The Aurivillius layer-structures, described by the general formula Bi2O2(Am-1BmO3m+1), are naturally 2-dimensionally nanostructured. They are very flexible frameworks for a wide variety of applications, given that different types of cations can beaccommodated both at the A- and B-sites. In this review article, we describe how the Aurivillius phases are a particularly attractive class of oxides for the design of prospective single phase multiferroic systems for multi-state data storage applications, as they offer the potential to include substantial amounts of magnetic cations within a strongly ferroelectric system. The ability to vary m yields differing numbers of symmetrically distinct B-site locations over which the magnetic cations can be distributed and generates driving forces for cation partitioning and magnetic ordering. We discuss how out-of-phase boundary and stacking fault defects can further influence local stoichiometry and the extent of cation partitioning in these intriguing material systems.
Learning leadership in outdoor education: Effects of feedback
Authors: Vigane Åge , Dyrstad Sindre M.
Published: January 2022

There is paucity of knowledge regarding learning outcomes from outdoor leadership training courses. The aim of this pilot study was to examine progress in perceived leadership skills after a six-month outdoor education course, and to examine the effect of systematic feedback from fellow students. Seventeen students were randomized into intervention and control groups and participated in six outdoor excursions during which they took leader roles. The intervention consisted of systematic use of feedback from fellow students. To assess the progress in students’ perceived outdoor leadership skills, the students answered a questionnaire covering four categories of leadership both before and after the course. Significant progress in perceived outdoor leadership was found for all students after the six-month course. Systematic feedback from fellow students did not seem to enhance students’ perceived outdoor leadership skills. The reasons could be that the feedback was not given in the actual situations or that the student feedback was not valued. Feedback from teachers and from nature (self-experience) were found to be important for strengthening perceived leadership skills.
Knowing-with-snow in an outdoor kindergarten
Authors: Bartnæs Pernille , Myrstad Anne
Published: January 2022

This article highlights how reciprocal relationships between children and the environment can contribute to exploring understanding of children’s learning in the outdoor environment. We draw on data from a kindergarten in the northern part of Norway, where we have carried out fieldwork three hours a week from October to mid-May. During this period, the outdoor area was covered with snow of varying qualities. Snow and weather conditions are included as elements in a relational understanding, in which the environment is understood as open and dynamic – an interaction between past and present, between geography, materiality, people and the ‘more-than-human’. The learner and the environment are understood as an indivisible process, where different elements exercise a reciprocal influence on each other. Using Ingold’s concept of correspondence, we explore how children learn by being within and with the world. The article is a contribution to creating a nuanced understanding of children’s learning and the educator’s role within an outdoor environment in kindergarten practice.
Epidemiology of Superficial Fungal Infections in Hospital Settings in Togo and Senegal from 2019 to 2020
Authors: Sow Doudou
Published: January 2022

Background: Superficial fungal diseases are cosmopolitan affections caused by yeast and filamentous microscopic fungi (dermatophytes and moulds). Their very high prevalence and worldwide distribution make them one of the most common dermatological diseases. Our study aims to describe the profile of superficial fungal diseases diagnosed in Senegal and Togo and to identify the causative agents circulating in both countries. Material and Methods: This is a descriptive study carried out in Senegal and Togo, involving 602 and 135 patients respectively. The patients presenting clinical signs were screened in the Parasitology-Mycology laboratories of the Fann University Hospital in Dakar (from February 2019 to February 2020) and Sylvanus Olympio University Hospital in Lomé (from October 2019 to March 2020). Samples collected were examined using routine mycological techniques (Direct examination and culture). Results: In Senegal 293 (48.67%) out of 602 patients enrolled were diagnosed with superficial fungal diseases. Patients under 10 old years and female, most affected, represented 23.42% and 61.39% of cases respectively. The patients were seen mostly in September with 27 positives cases out of 42. Trichophyton soudanense and Candida albicans complex were the most common species, with a prevalence rate of 30.37% and 26.96% respectively. In Togo, 67.41% (91) of the 135 patients presented superficial mycosis. The female (58.76%) and the patients aged 31-40 year old (21.65%) were the most affected. Highest prevalence is recorded in October with 11 positive cases out of 13. Malassezia furfur was the most common species with a prevalence of 28.57%. The same species of fungi were found in both countries with the exception of three fungi Trichophyton violaceum, Aspergillus candidus (respectively 3 cases and 1 case in Senegal) and Trichophyton tonsurans (3 cases in Togo). Conclusion: Superficial mycoses are a frequent reason for consultation in Senegal and Togo. Dermatophytes and yeasts of the genus Candida and Malassezia are the most common agents involved. The use of innovative diagnostic techniques could allow a more precise identification of species for a better therapeutic management.

This study aims to see the effect of Village Fund and Gross Domestic Regional Product on poverty in districts / cities in Aceh Province during the 2017-2019 period. To analyze the data, the method used is panel data regression analysis with the estimation of model parameters using a fixed effect model (FEM). The results showed that the village funds variable did not have a significant effect on poverty, this happened because most of the village funds were allocated more to the infrastructure development sector, causing village funds to still not have a direct effect on reducing poverty. The Gross Domestic Regional Product variable has a negative but significant effect on poverty in the District / City of Aceh Province, which means that with an increase in Gross Domestic Regional Product it will significantly affect the reduction of poverty levels in Aceh Province.

A DIMENSÃO LÚDICA E AS PRÁTICAS PEDAGÓGICAS PARTICIPATIVAS DAS CRIANÇAS NA AMAZÔNIA AMAPAENSE

Published: January 2022

A pesquisa investiga em que medida a dimensão lúdica está vinculada com práticas pedagógicas participativas das crianças na Amazônia amapaense? Objetivou-se compreender a relação da ludicidade e as práticas pedagógicas que reconhecem e valorizam a criança como sujeito participante e construtor de seu conhecimento. A metodologia utilizada se fundamentou na abordagem qualitativa, ancorada no método Estudo de Caso, tendo como principais técnicas e instrumentos de coleta de dados: a entrevista semiestruturada e o grupo focal com as professoras; as rodas de conversa com as crianças e a observação participante nos contextos de cada professora com suas crianças. O locus de pesquisa foi uma EMEI localizada em área urbana periférica do Município de Macapá/AP. Utilizou-se no tratamento dos dados, os princípios presentes na Hermenêutica-Dialética. Os resultados demonstram que o lugar ocupado pela dimensão lúdica encontra-se claramente definido nos documentos oficiais e no discurso pedagógico, mas mantem-se incompreendido e inferiorizado no contexto educacional, muito devido à burocratização e pedagogização docente e das exigências sociais que enaltecem práticas transmissivas e desqualificam práticas fundadas na participação e no reconhecimento da criança amazônica como sujeito histórico e cultural, pois estas não representam a lógica da sociedade capitalista.
AS IMPLICAÇÕES NO PROCESSO EDUCATIVO DAS CRIANÇAS DECORRENTES DA MIGRAÇÃO COMPULSÓRIA DO ENSINO PRESENCIAL PARA O ENSINO REMOTO EM UMA ESCOLA DE MACAPÁ/AP

Published: January 2022

O presente artigo tem por objetivo analisar as implicações da migração compulsória do ensino presencial para o ensino remoto na perspectiva de docentes alfabetizadores de uma unidade escolar do município de Macapá, capital do Estado do Amapá, que se deu a partir da pandemia de COVID-19 no ano de 2020 e permanece no ano de 2021. Este estudo é de abordagem qualitativa que se constitui a partir de uma pesquisa explicativa no âmbito da análise do conteúdo das respostas obtidas em questionário online aplicado aos docentes alfabetizadores de uma escola da rede pública municipal de Macapá/AP. Como resultado, observou-se que os docentes, em geral, se sentiram frustrados após receberem a determinação para ministrar as suas aulas remotamente, tendo em vista que apesar de receberem relativo treinamento e capacitação para ministração de suas aulas em um novo formato, os alunos e o sistema acabam por não favorecer o processo de ensino remoto em uma área periférica, por exemplo, onde grande parte dos responsáveis e alunos não possuem acesso à internet, outros nem aparelho celular tem, fazendo com que a alfabetização, etapa importante da escolarização, reste prejudicada.
