The purpose of this research is to produce a development product in the form of a Magnetic Levitation Train miniature model that can be used by teachers and students in the physics learning process on magnetic force material in class XII. This study uses research and development methods. The research was conducted through several stages, namely the first stage reviewing curriculum standard notes. The second stage is the design of the tool, making a miniature model of the Magnetic Levitation Train and the use of a miniature model of the Magnetic Levitation Train in the learning process. The third stage is the implementation stage, the miniature model of the Magnetic Levitation Train was tested on high school student of class XII to measure students against the miniature model of the Magnetic Levitation Train as a tool to help students understand the concept of magnetic force. The instrument uses a Likert Scale. With three stages, the researcher succeeded in making a miniature model of the Magnetic Levitation Train that was worthy of being one of the learning media on magnetic force material by obtaining information that the validation results by experts, material personnel and students obtained a very good level of measurement which was in the interpretation range of scores 80-100% so it is necessary to develop a miniature model of the Magnetic Levitation Train to be even better in further research.

Published: February 2021

This study aims to analyze the influence of the guided inquiry learning model in physics learning through the overall effect size, based on the dependent variable and region. This research uses a descriptive method with a meta-analysis approach to the results of scientific research publications in national electronic journals. There are 11 national journals that fit the research category. The results showed that overall learning using the guided inquiry model could improve students' physics learning outcomes with the effect size of 0.487 from the control group. Meanwhile, based on the distribution of regions in Indonesia, an average effect size of 0.527 is obtained and based on the dependent variable an effect size is obtained of 0.425. These three results indicate a large effect size guided inquiry learning model in physics learning. This shows that the guided inquiry learning model can provide a more effective effect and is suitable for use in learning physics.

Does serotonin deficiency lead to anosmia, ageusia and dysfunctional chemesthesis in COVID-19?
Authors: Sen Amarnath
Published: February 2021

Anosmia, ageusia and impaired chemesthetic sensations are quite common in coronavirus patients. Different mechanisms have been proposed to explain the anosmia and ageusia of COVID-19 patients, though for reversible anosmia and ageusia, which are resolved quickly, the proposed mechanisms seem to be incomplete. In addition, the reason behind the impaired chemesthetic sensations of some coronavirus patients remains unknown. It is proposed that in coronavirus patients, there is depletion of tryptophan (an essential amino acid), as ACE2, a key element in the process of absorption of tryptophan from food, is significantly reduced due to the attack of coronavirus which use ACE2 as the receptor for its entry into the host cells. Incidentally, the depletion of tryptophan should lead to deficiency of serotonin (5-HT) in SARS-COV-2 patients because tryptophan is the precursor in the synthesis of 5-HT. Such 5-HT deficiency not only explains fast resolved anosmia and ageusia, but also dysfunctional chemesthesis, given the fact that 5-HT is an important neuromodulator in the olfactory neurons and taste receptor cells and 5-HT also enhances the nociceptor activity of transient receptor potential channels (TRP channels) responsible for chemesthetic sensations. The female predominance of olfactory and gustatory dysfunctions can also be explained by considering low 5-HT levels in women. In addition, 5-HT deficiency worsens silent hypoxemia and explains why hypoxic pulmonary vasoconstriction is nearly absent in coronavirus patients leading to poor outcome. Hence, clinical trials should be conducted on coronavirus patients to find out how different selective serotonin reuptake inhibitors (SSRIs) and serotonin agonists work out in eliminating or improving the olfactory, gustatory and chemesthetic dysfunctions as well as hypoxemia.
The role of intolerance of uncertainty in classical threat conditioning: Recent developments and directions for future research
Authors: Morriss Jayne , Zuj Daniel , Mertens Gaëtan
Published: February 2021

Intolerance of uncertainty (IU), the tendency to find uncertainty aversive, is an important transdiagnostic dimension in mental health disorders. Over the last decade, there has been a surge of research on the role of IU in classical threat conditioning procedures, which serve as analogues to the development, treatment, and relapse of anxiety, obsessive-compulsive, and trauma- and stressor-related disorders. This review provides an overview of the existing literature on IU in classical threat conditioning procedures. The review integrates findings based on the shared or discrete parameters of uncertainty embedded within classical threat conditioning procedures. Under periods of unexpected uncertainty, where threat and safety contingencies change, high IU, over other self-reported measures of anxiety, is specifically associated with poorer threat extinction learning and retention, as well as overgeneralisation. Under periods of estimation and expected uncertainty, where the parameters of uncertainty are being learned or have been learned, such as threat acquisition training and avoidance learning, the findings are mixed for IU. These findings provide evidence that individual differences in IU play a significant role in maintaining learned fear and anxiety, particularly under volatile environments. Recommendations for future research are outlined, with discussion focusing on how parameters of uncertainty can be better defined to capture how IU is involved in the maintenance of learned fear and anxiety. Such work will be crucial for understanding the role of IU in neurobiological models of uncertainty-based maintenance of fear and anxiety and inform translational work aiming to improve the diagnosis and treatment of relevant psychopathology.
Dissociation Between Speech and Emotion Effects in Short-Term Memory: A Data Reanalysis
Authors: Wiens Stefan
Published: February 2021

Performance in visual serial recall tasks is often impaired by irrelevant auditory distracters. The duplex-mechanism account of auditory distraction states that if the distracters provide order cues, these interfere with the processing of the order cues in the serial recall task (interference by process). In contrast, the unitary account states that distracters capture only attention on a general level (attentional distraction) without interfering specifically with order processing. Marsh et al. (2018, Journal of Experimental Psychology-Learning Memory and Cognition, 44, 882-897) reported finding a dissociation between the effects of serial recall tasks and those of a missing-item task on the disruptive effects of speech and of emotional words, as predicted by the duplex-mechanism account. Critically, the reported analyses did not test specifically for the claimed dissociation. Therefore, I reanalyzed the Marsh et al. data and conducted the appropriate analyses. I also tested the dissociation more directly and added a Bayesian hypothesis test to measure the strength of the evidence for a dissociation. Results provided strong evidence for a dissociation (i.e., crossover interaction) between effects of speech and of emotion. Because the duplex-mechanism account predicts this dissociation between speech effects (interference by process) and emotion effects (attentional diversion) whereas the unitary account does not, Marsh et al.’s data support the duplex-mechanism account. However, to show that this dissociation is robust, researchers are advised to replicate this dissociation in an adversarial registered report.
Is Differential Noneffortful Responding Associated with Type I Error in Measurement Invariance Testing?
Authors: Rios Joseph
Published: February 2021

Low test-taking effort as a validity threat is common when examinees perceive an assessment context to have minimal personal value. Prior research has shown that in such contexts subgroups may differ in their effort, which raises two concerns when making subgroup mean comparisons. First, it is unclear how differential effort could influence evaluations of scale property equivalence. Second, if attaining full scalar invariance, the degree to which differential effort can bias subgroup mean comparisons is unknown. To address these issues, a simulation study was conducted to examine the influence of differential noneffortful responding (NER) on evaluations of measurement invariance and latent mean comparisons. Results showed that as differential rates of NER grew, increased type I errors of measurement invariance were observed only at the metric invariance level, while no negative effects were apparent for configural or scalar invariance. When full scalar invariance was correctly attained, differential NER led to bias of mean score comparisons as large as 0.18 standard deviations with a differential NER rate of 7%. These findings suggest that test users should evaluate and document potential differential NER prior to both conducting measurement quality analyses and reporting disaggregated subgroup mean performance.
From task-general to task-specific cognitive operations in a few minutes: Working memory performance is an adaptive process

Published: February 2021

Measurement of cognitive functions is typically based on the implicit assumption that the mental architecture underlying cognitive task performance is constant throughout the task. In contrast, skill learning theory implies that cognitively demanding task performance is an adaptive process that progresses from effortful and task-general metacognitive and control processes to more automatic and task-specific performance. However, this hypothesis is rarely applied to the short time spans of traditional cognitive tasks such as working memory (WM) tasks. We utilized longitudinal structural equation models on two well-powered data sets to test the hypothesis that the initial stages of WM task performances load on a task-general g-factor and then diverge into factors specific to task structure. In line with the hypothesis, the first experiment (N = 296) indicated perfect correlation between latent factors in the beginning of the task, which then diverged into task-specific factors. The second experiment (N = 201) indicated unity between all except one latent factor in the beginning of the task, followed by divergence. These results can be interpreted in the skill learning framework as suggesting that the mental architecture underlying complex cognitive performance progresses rapidly from initial engagement of task-general cognitive processes towards task-specific ones. This has several important implications for the measurement of complex cognitive functions.
Child Abuse Subtypes and Automatic Emotion Regulation Processes in Children and Adolescents
Authors: Kim Stephanie Gyuri , Weissman David , Sheridan Margaret , McLaughlin Katie A
Published: February 2021

Child abuse is associated with elevated risk for psychopathology. The current study examined the role of automatic emotion regulation as a potential mechanism linking child abuse with internalizing psychopathology. A sample of 237 youth aged 8–16 years and their caregivers participated. Child abuse severity was assessed by self-report questionnaires, and automatic emotion regulation was assessed using an emotional Stroop task designed to measure adaptation to emotional conflict. A similar task without emotional stimuli was also administered to evaluate whether abuse was uniquely associated with emotion regulation, but not cognitive control applied in a non-emotional context. Internalizing psychopathology was assessed concurrently and at a two-year longitudinal follow-up. Child abuse severity was associated with lower emotional conflict adaptation but was unrelated to cognitive control. Specifically, the severity of emotional and physical abuse, but not sexual abuse, were associated with lower emotional conflict adaptation. Emotional conflict adaptation was not associated with internalizing psychopathology prospectively. These findings suggest that childhood emotional and physical abuse, in particular, may influence automatic forms of emotion regulation. Future work exploring the socioemotional consequences of altered automatic emotion regulation among youth exposed to child abuse is clearly needed.
The Future of French in Uganda in the Context of Language Policy Challenges: A Situational Analysis
Authors: Togboa Edith Natukunda , Tumwine Agatha , Ebil Moses Wang’koko
Published: February 2021

In Uganda, publishing in French dates back to more than a century while its teaching dates from the early 1950s. Despite the position of English as the official language, French has for a long time been enjoying a privileged institutionalised position as a language of culture and a vehicle of international cooperation. French is offered as a foreign language at the secondary and tertiary levels of education and has been introduced in some private primary schools. Currently, however, French is facing language policy challenges in Uganda. One wonders how secure the future of French is in Uganda alongside the triumphant universal English language, the “national” flag bearer Kiswahili and the thunderous new arrival of Chinese. While choices between the indigenous, national and international languages are narrowing down, the promoters and developers of French must search for new niches for French as a language of inter-culturalism and interdependence.

Authors: Kisige Abdu , Ezati Betty Akullu , Kagoda Alice Merab
Published: February 2021

Developing a teacher education curricular content is an enduring concern for teacher educators. A continuous method to providing quality teacher education curriculum content discloses the potential for teacher educators to produce high-quality teachers. Drawing on data from twenty teacher educators and sixteen student teachers in public institutions in Uganda, this article explored the perceptions of the teacher education curriculum content held by academic staff and student teachers in public Universities in Uganda. Using Pedagogical Content Knowledge Model as a tentative model of teacher preparation and Constructivism theory as an interpretive framework, the study was guided by one objective namely: (1) to analyze the perception of internal stakeholders about teacher education curriculum content offered in Makerere and Kyambogo Universities. This research adopted a qualitative, multiple case study design that was anchored in the interpretivist paradigm and directed by the social constructivism thinking. Data were collected using semi-structured interviews were participants from twenty teacher educators and sixteen student teachers who were purposively and conveniently selected. It was therefore concluded that both lecturers and student teachers viewed teacher education curriculum content positively viewing it as enabling learners to be equipped with specialized teaching skills, essentially directed towards teaching profession. Thus, recommendations to improve the stakeholder perception of the teacher education curriculum content are made and these include: teacher education curriculum review and the need to design a 21st-century teacher education curriculum by teacher trainers in corroboration with other university units rendering a training service to teacher trainees. This would bridge the gap of the disjointed teacher education curriculum content at Makerere and Kyambogo Universities hence strengthening the building blocks that produce a teacher.

The Act of 5 July 2018 on the succession administration of the business of a physical person introduced a possibility to carry out transactions relating to establishing and performing administration of the estate. In particular, the Act permits to appoint a succession administrator and empowers him or her to carry out legal transactions relating to the business of the deceased entrepreneur. A need to determine the law applicable to these legal transactions arises. The article contains an analysis of the conflict rules adopted in the EU Succession Regulation. From this analysis the author draws a conclusion that the appointment of the succession administrator and the legal acts relating thereto are subject to the law applicable to succession. Likewise one should classify legal transactions relating to the administration of the business undertaken by persons named in the Act to carry out administration in the period before the succession administration is established. The prerequisites of the validity of the legal transactions carried out by the effectively nominated succession administrator on the other hand are subject to the law applicable to the given legal transactions, as according to general rules relating thereto. This includes, inter alia, that the legal acts falling with the scope of the law applicable to succession (Article 23 of the Succession Regulation), are governed by that law.

Published: February 2021

Os sistemas agroflorestais (SAF) são alternativas importantes para gerar renda com agricultura sustentável, a exemplo dos SAF no Litoral Norte do Rio Grande do Sul. Porém, ainda são poucos os trabalhos que utilizam a abordagem da agricultura ou floresta de precisão, com uso da espacialização de atributos da vegetação dos SAF, sendo este o objetivo desta pesquisa. Foi realizado um inventário num SAF silvibananeiro localizado em Três Cachoeiras, sendo instaladas 33 unidades amostrais (ua) para mensuração dos indivíduos arbóreos com CAP >15 cm. As ua foram georreferenciadas, localizando os parâmetros fitossociológicos, que foram interpolados por ponderação pelo inverso da distância (IDW) no gvSIG, que juntamente com os limites do SAF deram origem a mapas de variabilidade espacial. A principal espécie observada foi palmito juçara (Euterpe edulis Mart. - Família Arecaceae) com 75 indivíduos amostrados, com dominância, frequência e densidade relativas de 17, 22,2 e 37%, respectivamente, e importância de importância de 76,2 %. As variáveis que apresentaram variabilidade espacial evidente foram número de espécies, diversidade máxima, os índice de diversidade, dominância e equabilidade, número de palmiteiros e de cachos de banana verde.  Conclui-se que os atributos do SAF silvibananeiro possuem variabilidade espacial e que a metodologia utilizada foi adequada.

Objetivou-se avaliar a interação entre diferentes níveis salinos e substratos sob o crescimento inicial, o acúmulo de biomassa e as trocas gasosas da cultura do feijão-caupi. O experimento foi conduzido na área experimental da Universidade Federal do Ceará, Fortaleza, Ceará. O delineamento utilizado foi inteiramente casualizado em esquema fatorial (5 x 2), com quatro repetições. Os tratamentos foram constituídos por substratos inseridos ao solo (T1- biocarvão + solo na proporção 1:1; T2- solo (testemunha); T3- adubação mineral; T4- casca de arroz carbonizada + carnaúba + solo na proporção 2:1:1 e S5- casca de arroz carbonizada + solo na proporção 1:1), e duas águas de irrigação (1,0 e 4,0 dS m-1). Aos 40 dias após a semeadura (DAS) foram avaliados: número de folhas (NF), altura de planta (AP), diâmetro do caule (DC), área foliar (AF), massa seca da parte aérea (MSPA) e total (MST), fotossíntese (A), transpiração (E) e condutância estomática (gs). A água de alta salinidade afetou negativamente a AP, DC, MSPA e a gs das plantas. Os tratamentos T4 e T5 promoveram maior NF e A quando combinado com água não salina. Os tratamentos T4 e T5 proporcionaram maiores valores de gs e E.

Influence of saline stress and fertilizers on caupi bean crop
 
ABSTRACT: The objective was to evaluate the effects of salt stress on the initial growth, on the accumulation of biomass and on the gas exchange of the cowpea culture submitted to different substrates. The experiment was conducted in the experimental area of the Federal University of Ceará, Fortaleza, Ceará. The design used was completely randomized in a factorial scheme (5 x 2), with four replications. The treatments consisted of substrates inserted in the soil (T1- biochar + soil in the proportion 1: 1; T2- soil (control); T3- mineral fertilization; T4- carbonized rice husk + carnauba + soil in the proportion 2: 1: 1 and S5- carbonized rice husk + soil in a 1: 1 ratio), and two irrigation waters (1.0 and 4.0 dS m-1). At 40 days after sowing (DAS), the following were evaluated: number of leaves (NF), plant height (AP), stem diameter (DC), leaf area (AF), shoot dry matter (MSPA) and total (MST), photosynthesis (A), transpiration (E) and stomatal conductance (gs). High salinity water negatively affected AP, DC, MSPA and plant gas. The treatments T4 and T5 promoted greater NF and A when combined with non-saline water. The treatments T4 and T5 provided higher values of gs and E.
Keywords: Vigna unguiculata L. Walp; salinity; fertilization.
Infranatant Portion of Microfragmented Adipose Tissue: A Promising Source of SVF for the Management of Androgenetic Alopecia
Authors: Gennai Alessandro , Gennai Alessandro , Tesauro Piero , Colli Mattia , Zia Silvia , Roda Barbara , Zattoni Andrea
Published: February 2021

Aim: The purpose of this article is to prove the possibility to transfer a good amount of cells of the SVF
(and ADSCs) in the infranatant portion of microfragmented adipose tissue.
Method: The adipose tissue harvesting procedure is performed under local anaesthesia. The adipose tissue
was harvested with a 2 mm diameter microperforated cannula with 1 mm side port holes, mounted inside
the special patented guide. Both cannula and guide are included in the SEFFIHAIR™ medical device. Once
the adipose tissue is harvested, it is gently washed, and it was divided in two specimens: (EMU) the tissue
was emulsified with 20 passages from one syringe to another and (CTRL) the tissue didn’t undergo any
emulsification.
Results: The emulsification procedure liberated alive and proliferating cells and we observed that the
specimens derived with a 1 mm side port hole cannula and then emulsified (EMU) showed a higher number
of cells in the infranatant part compared to the one derived from the control tissue without any (1 EMU vs.
1EMU infra).
Conclusion: The use of microcannulas, in combination with a mechanical digestion by an emulsification
procedure and centrifuge, could ease SVF cells isolation for regenerative treatment and could also be
performed in a medical facility.
Systemic Vasculitis Mimics Pancreatic Tumor

Published: February 2021

The systemic vasculitides are heterogeneous conditions of unknown etiology characterized by inflammation
and necrosis of different sized blood vessels. The epidemiology of the systemic vasculitides is poorly
documented, but it is a rare disease. The abdominal manifestation of systemic vasculitis (SV) is a rarity. A
67-year-old man with a history of diabetes insipidus and bilateral ear canal stenosis presented with bilateral
lower abdominal pain for three days duration and postprandial nausea and regurgitation for two weeks
duration. He also complained of weight loss during the last year, decrease in general performance, and
impaired hearing associated with ear bleeding. The patient was diagnosed with unspecified acoustic meatus
stenosis by ear, nose, and throat (ENT) specialist. Computed tomography (CT) scan revealed a pancreatic
lesion, which was biopsied under endosonographic guidance without any informative result. For further
histological evaluation laparotomy was indicated and multiple histological materials were taken.
Unfortunately, histological results revealed no specific diagnosis either. In the blood tests there were no
signs of autoimmune or rheumatologic disease. By the daily deterioration of the patient's general condition,
we carried out a Positron emission tomography-CT scan, which revealed SV. Under cortisone therapy the
patient’s complaints obviously declined, the patient rejected further investigation such as vascular biopsy.
The intraabdominal vasculitis represents an unusual pathological finding, which, however, manifests itself
only as a rare variation of an everyday medical constellation. The case impressively illustrates how difficult
is to establish the correct diagnosis of abdominal vasculitis.
UM NOVO OLHAR SOBRE A CONSTITUCIONALIDADE DO FUNRURAL: O PRINCÍPIO DA SEGURANÇA JURÍDICA
Authors: Carolina Costa da Mota Soares Maria , Sales Queiroz de Lima Siberia
Published: February 2021

O presente trabalho aprofundar-se-á, no que concerne às áreas do Direito Tributário e Direito Constitucional, no entendimento da cobrança do FUNRURAL. Busca-se compreender se a manutenção do FUNRURAL trouxe como consequência um cenário de insegurança jurídica, principalmente aos seus contribuintes. Percebendo as consequências causadas pela manutenção da indigitada cobrança, dentre as quais ganha destaque a ameaça à segurança jurídica, prevista no art. 5º da Constituição Federal (CF), um sobreprincípio de grande importância, devido ser o mesmo regulador da sociedade em prol da estabilidade das relações jurídicas e, no aspecto subjetivo, da proteção à confiança ou confiança legítima. Esta pesquisa buscou investigar a possível insegurança jurídica provocada por mudanças bruscas na jurisprudência pátria em relação ao entendimento da justiça quanto à cobrança do FUNRURAL e perceber os prejuízos causados aos contribuintes dessa contribuição rural. A pesquisa foi de cunho bibliográfico e documental, adotando como referência teórica predominante a base teórica adotada por Carvalho (2009). Ficou evidente que as múltiplas modificações legislativas e jurisprudenciais verificadas na história do FUNRURAL levaram à insegurança jurídica quanto ao cumprimento das obrigações tributárias concernentes a esse tributo.
DIREITO AO ESQUECIMENTO E A RESPONSABILIDADE CIVIL DOS PROVEDORES DE INTERNET
Authors: Souza Aguiar Hislla , Alves Gonçalves Karine
Published: February 2021

O presente artigo tem por objetivo abordar o Direito ao Esquecimento, apesar de não haver dispositivo legal específico que trate dele, de modo que o seu princípio encontra amparo na Constituição Federal de 1988, na jurisprudência e doutrina. A tutela juridicamente protegida é o direito da personalidade, em especial a privacidade e dignidade da pessoa humana. Consiste em uma garantia que o indivíduo possui de não permitir que um fato passado, ainda que verídico, seja disponibilizado ao público em geral. Nesse sentido, há colisão entre a inviolabilidade da vida privada e o direito à informação, utilizando o princípio da ponderação para decidir qual será aplicado ao caso concreto. O trabalho se desenvolveu por meio do método exploratório, hipotético-dedutivo, por meio de pesquisas documentais e bibliográficas. Assim, em determinadas situações, um fato de sua vida não pode causar sofrimento ou transtornos, já que as pessoas têm o direito de serem esquecidas pela opinião pública e até pela imprensa, pois suas ações não devem lhe perseguir como uma punição eterna.

Published: February 2021

O Brasil convive, há muitos anos, com um dos grandes problemas na educação que é a falta de profissionais qualificados para a profissão docente, fato decorrente do fato de que grande parte da população elege as licenciaturas como última opção para cursar ao ingressar no nível superior. Diante do exposto, desenvolveu-se uma pesquisa na cidade de Palmas -TO com o objetivo de verificar o possível desinteresse da população local pela profissão docente. Foram objetivos específicos desta investigação: determinar quais os principais fatores que influenciam o desinteresse pela profissão docente; apresentar os cursos de ensino superior mais escolhidos para serem cursados pelos palmenses. Esta é uma pesquisa quali-quantitativa exploratória, visando utilizar os conceitos essenciais de Estatística para o tratamento de dados, a fim de extrair e coletar informações para a verificação da hipótese. Detectou-se que um dos  grandes fatores que influenciam a população a rejeitar a carreira de professor é  a falta de informação, dado que não sabem o salário  de um  professor da educação básica da rede pública de ensino.

O artigo tem como objetivo apresentar um estudo comparativo de custo entre a construção por impressora 3D e alvenaria estrutural, pensando na necessidade de diminuir o déficit na construção de habitações de interesse social. Trata-se de um estudo bibliográfico, com abordagem quantitativa, fundamentada em análises feitas em artigos científicos, revistas, livros e documentos disponibilizados pela Caixa Econômica Federal com o intuito de buscar e avaliar as técnicas de construção adotada na problemática da pesquisa. Os principais resultados encontrados demonstraram que 18,5% dos custos com o método construtivo por alvenaria estrutural está relacionada ao revestimento. Levando em conta os métodos adotados foi notório a diferença de custo entre construção por impressora 3D e alvenaria estrutural, na qual a impressão pela ICON e WINSUN chegaram a ter uma redução nos custos de 50% e 39% quanto ao método de alvenaria estrutural, entretanto não foram levados em conta custos como instalação, mão de obra qualificada e aquisição do maquinário, o que não deixa de demonstrar que a aplicabilidade da impressão 3D pode causar mudanças significativas para o setor. Os dados levantados neste artigo podem contribuir com uma melhor visibilidade no sentido de mecanização dos processos construtivos, possibilitando a incrementação de métodos que possam contribuir com a redução de custos na construção de novas moradias. Pode-se afirmar que a utilização de impressoras 3D na construção demonstrou alto potencial de utilização e pode ser uma ferramenta capaz de diminuir os custos financeiros e ambientais, entretanto este pode ser um grande desafio para a construção civil.

Gender Comparison on Teaching Practices of One Teacher Schools
Authors: Rafiq Mona , Sultana Naveed
Published: February 2021

Primary schools in rural areas of Pakistan have been opened at very short distance firstly due to small geographical boundaries of the villages and secondly to improve the enrollment of students. The small population in villages resulted in low enrollment of the students. According to rationalization policy of Government of Pakistan, the student-teacher ratio is 35:1; therefore, student strength of schools in rural areas hardly reaches 40; hence, a single teacher is allocated, and students in a school from Zero grade to 5th grade sit together in either one room or two and are taught by mostly one or two teachers concurrently This qualitative study was conducted in rural primary schools for girls and boys to explore lived experiences of male and female teachers in One Teacher Schools/multi-grade and to find out differences in teaching on the gender-disaggregated basis. The management of multi grades single-handedly is the toughest job.

Published: February 2021

It is estimated that by 2025, tourism & hospitality sector will contribute US$7.1 billion (₨ 1 trillion) to the economy of Pakistan. However, one can only attach such high hopes to this sector when human resource in this sector displays prosocial behavior to both domestic and foreign tourists. The objective of the study is to examine the level of antisocial behavior of the managers working in this sector and test its relationship with moral disengagement. We also examine ethical orientation as mediator and ethical leadership as moderator in this relationship. Data were collected from 253 managers working in the hospitality and tourism sector of Pakistan. We find that moral disengagement has significant effect in promoting antisocial behavior by easing and expediting a process where actors convince themselves that ethical standard do not apply on them. We also find that ethical orientation mediates and ethical leadership moderates this relationship respectively.

The scientific article explores the problem of using the electronic language Portfolio in bilingual education as the latest method of presenting a pupils' foreign language activities. Its importance at the present stage of education development is substantiated. The role of the electronic platform in the educational bilingual process is analyzed, as with the development of the latest digital technologies there have also been changes in its organization. It is established that the electronic Portfolio is used in bilingual education as the latest method of storage and presentation of the works carried out by the pupils. It presents feedback, recommendations of teachers regarding foreign language activities of the student. It is a kind of platform for discussions, as the Portfolio can serve in the educational environment to connect the pupil and the teacher, to present the achievements and successes of the pupil in foreign language activities. It is established that in the context of bilingual education, the European language Portfolio offers clear, systematic descriptors of pupils' knowledge and skills in mastering foreign languages, and is also used to assess student achievement. This motivates them to work better, allows them to identify gaps in their learning. In the context of bilingual education, the Portfolio can be used to compare and evaluate the level of foreign language skills of the pupils, which allows the teacher to adjust their intervention in the bilingual educational process. It is stated that in today's conditions the electronic language Portfolio is especially effectively used in bilingual education, as it provides interaction between peers, serves as a means of communication between the pupil and the teacher, the teacher and the parents. The use of electronic language Portfolio in bilingual education promotes the integration of positive experience of foreign language activities, encourages pupils to implement its practical aspects, establishes the foundation for professional development.
Seminole Food: Patterns of Indigenous Foodways in South Florida, 1855 to 1917
Authors: Gonzalez Albert D
Published: February 2021

Few systematic historical studies of Seminole Indian foodways in Florida exist, fewer even for the critical period between Removal and World War I.  This paper aims to fill the gap in related foodways and historical literature, while establishing a starting point for zooarchaeological and archaeobotanical studies on the topic.  It addresses the issue from the ground up, developing an inventory of Seminole selective preferences in terms of food and tracking changes in those preferences over time.  The study borrows the use of presence/absence matrices from archaeology to facilitate that analysis, treating an extensive set of related documents as a stratified matrix in which historical observations of Seminole food consumption are recorded by food type.  It relies on Seminole oral histories to supplement the document index by providing additional information as to food preferences and taboos.  Results of data analysis lead me to the conclusion that two complimentary channels of foodways existed among Seminole Indians in South Florida at the time: (1) a conservative channel that maintained symbolically and nutritionally important foods and, (2) a more flexible channel that allowed for the incorporation of supplementary foods of various origins.
The The Effects of Soft Tissue Removal Methods on Porcine Skeletal Remains
Authors: Tarbet Hust Emily Siobhan , Snow Meradeth H
Published: February 2021

Sus scrofa domesticus limbs were obtained as a human proxy to study the effects of five distinct materials used in published methods of flesh removal: Dermestes lardarius beetles (also referred to as dermestids), distilled-water boil, bleach boil, enzyme-based detergent simmer, and ammonia simmer. Each method was evaluated based on a set of specific criteria, focusing on time efficiency, macroscopic damage, and the effects on DNA preservation and potential for future analysis.  

While the dermestid beetles had the longest time-expectancy and was the most labor-intensive, they caused minimal damage to the bone surface and did not appear to affect the DNA preservation. Heated maceration methods sped up the process considerably, but that often led to decreased DNA quantity and minimal to severe amounts of macroscopic damage. The ammonia simmer method was the only method tested that was found in zoological literature but did not appear to have any published use within the forensic field, operating occasionally instead as a degreasing agent. While the ammonia was the most potent of the methods, it was efficient, low-cost, and left amplifiable DNA, perhaps indicating a potential future in more forensic contexts. 

Each method proved to have different advantages and disadvantages, with no method performing the best or worst in every evaluated criteria. The results of this research highlight how differently each method performs and how easily bone material can be affected. Method selection can severely impact later research and analysis and the choice demands to be made with consideration and awareness of the potential risks and desired results.
