Tunable Filter
Authors: Lu Di
Published: May 2022

Tunable filters enable dynamic spectrum access for the wireless systems, and the tunable bandpass filters with constant bandwidth (BW) are most favorable for practical applications. This chapter investigates the synthesis and realization techniques for the tunable filters using the coupling matrix with variable entries synthesizes the tunable filter and guides the filter design. The synthesis method and the matrix extraction procedures for the constant-bandwidth bandpass filter are included, and the typical numerical examples are given. This chapter also discusses the relationship between the theoretical matrix and the physical circuits, and then a planar tunable filter design is presented to verify this relationship. Furthermore, the general approach to designing the constant-bandwidth filters using the element variable coupling matrix is concluded. The planar circuit, as well as the 3D structure realizations, are offered to practically demonstrate the synthesis design approach.
Toxicity Status and Risks of Common Active Ingredients in Open Markets
Authors: Omoyele Adeniyi Dele
Published: May 2022

Agrochemical stores in selected geographical locations in North Central Nigeria were surveyed, a structured questionnaire administered and students of selected Universities and staff of the Ministry of Agricultural and Rural Development were sampled. Seventeen active ingredients: Paraquat dichloride, Glyphosate, Permethrin + pyriproxyfen, Dimethylamine salt, Cypermethrin, Chlorpyrifos, Dichlorvos, Lambda-cyhalothrin, 2,2-dichlorovinyl Dimethyl phosphate, Hexaconazole, Imidacloprid, Dimethoate, Nicosulfuron, Profenofos + cypermethrin, S-metolachlor, Carbendazim, and Mancozeb were recorded, and dominated by herbicides and insecticides. Toxicity analysis of active ingredients in open markets based on the recommendation of international standard organizations showed that some common active ingredients were not approved and some others were not listed for agricultural use. Many of the active ingredients negatively affect plant pollinators, aquatic animals, are highly toxic to birds, honey bees, and poses risk to wildlife. Some others are a possible carcinogen, fatal if inhaled, highly hazardous with high environmental toxicity posing a serious health risk to humans by disrupting the endocrine system, inducing heritable mutations in germ cells, impair fertility and reproductive toxicity.
On the Use of Modified Winsorization with Graphical Diagnostic for Obtaining a Statistically Optimal Classification Accuracy in Predictive Discriminant Analysis
Authors: Iduseri Augustine
Published: May 2022

In predictive discriminant analysis (PDA), the classification accuracy is only statistically optimal if each group sample is normally distributed with different group means, and each predictor variance is similar between the groups. This can be achieved by accounting for homogeneity of variances between the groups using the modified winsorization with graphical diagnostic (MW-GD) method. The MW-GD method involves the identification and removal of legitimate contaminants in a training sample with the aim of obtaining a true optimal training sample that can be used to build a predictive discriminant function (PDF) that will yield a statistically optimal classification accuracy. However, the use of this method is yet to receive significant attention in PDA. An alternative statistical interpretation of the graphical diagnostic information associated with the method when confronted with the challenge of differentiating between a variable shape in the groups of the 2-D area plot remains a problem to be resolved. Therefore, this paper provides a more comprehensive analysis of the idea and concept of the MW-GD method, as well as proposed an alternative statistical interpretation of the informative graphical diagnostic associated with the method when confronted with the challenge of differentiating between a variable shape in the groups of the 2-D area plot.
Internal Flow and Spray Dynamics of Multi-Hole Nozzle
Authors: Dong PengBo
Published: May 2022

Faced with dual challenges of “carbon neutral” and emission control, fossil fuel-based internal combustion engines need to explore new ways and technical paths to reduce harmful emissions and Carbon dioxide emissions simultaneously. Fuel injection process is playing a significant role not only in traditional engines but also in new low/zero carbon engines. Multi-hole nozzles have a wide range of applications in the fuel supply system. While the accepted spray study work and jet break-up models are usually developed under the quasi-steady-state of fuel injection by a single-hole nozzle. There are rare models that can describe the whole break-up processes of multi-hole nozzle spray, including complex internal flow factors, plume interaction, and the effect of start/end of injection. In this chapter, characteristics of spray morphology, evolution processes, and evaporation characteristics, emerging from the practical diesel multi-hole nozzles, were discussed and analyzed during the transient injection processes in detail. Moreover, the relationship between multi-hole nozzle internal flow properties and the corresponding spray behaviors was investigated by numerical simulation method systematically. Therefore, multi-hole spray modeling processes under engine operating conditions and the optimized design of diesel multi-hole nozzles are expected to get some benefits and clues from the current results.

: Melissa officinalis L. (MO), traditionally referred to as lemon balm, is one of the lemon-scent aromatic herbs widely used in traditional medicine due to its calming, sedative, and anti-arrhythmic effects. Furthermore, several studies have linked its therapeutic potential with its antioxidant properties. Here, we aimed to evaluate and compare the content of active components, antioxidant, and anti-inflammatory potential of three different MO extracts (MOEs), ethanolic macerate (E1), aqueous (E2), and ethanolic (E3), obtained under reflux and their effects on systemic redox status after acute per os administration in vivo post-carrageenan application. The HPLC analysis revealed that the most abundant constituent in all the three extracts was rosmarinic acid (RA), with higher content in E1 and E3 than in E2 (P < 0.05). The highest flavonoid content was found in the aqueous extract, especially quercetin (P < 0.05). For the carrageenan-induced paw edema model, dark agouti rats were used and divided into the groups: Control, indomethacin, E1, E2, and E3 subgrouped according to applied doses: 50, 100, and 200 mg/kg. Ethanolic macerate (E1200) and aqueous (E2100) MOE were shown to be anti-inflammatory agents in the carrageenan paw edema model, with the most prominent edema inhibition in the sixth hour post-carrageenan (63.89% and 69.44%, respectively, vs. 76.67% in the indomethacin group). All the three extracts reduced the production of pro-oxidants H2O2 and TBARS post-carrageenan and increased GSH levels compared to control (P < 0.05). These data imply the possible future usage of MOEs to prevent inflammatory and oxidative stress-related diseases.
Are People Part of Nature? Yes and No
Authors: Deplazes-Zemp Anna ,   Center for Environmental Philosophy, The University of North Texas
Published: May 2022

The question of whether or not people are part of nature is relevant to discuss humans’ role on earth and their environmental responsibilities. This article introduces the perspectival account of the concept of ‘nature,’ which starts from the observation that we talk about the environment from a particular, human perspective. In this account, the term ‘nature’ is used to refer to those parts of and events in the environment we perceive as being shaped by typically human activities. Humans themselves are part of nature insofar as they participate in and are products of natural processes. Therefore, in this account, nature is not only the passive environment, but also something active and generative that does not operate human creativity, but rather and it in shaping our environment. According to the perspectival account, the ‘nature’ concept expresses a particular relationship between the human agent and the non-human environment, which can be the starting point for normative theory.
Probability without Tears
Authors: Staffel Julia ,   Philosophy Documentation Center
Published: May 2022

This article is about teaching probability to students of philosophy who don’t aim to do primarily formal work in their research. These students are unlikely to seek out classes about probability or formal epistemology for various reasons, for example because they don’t realize that this knowledge would be useful for them or because they are intimidated by the material. However, most areas of philosophy now contain debates that incorporate probability, and basic knowledge of it is essential even for philosophers whose work isn’t primarily formal. In this article, I explain how to teach probability to students who are not already enthusiastic about formal philosophy, taking into account the common phenomena of math anxiety and the lack of reading skills for formal texts. I address course design, lesson design, and assignment design. Most of my recommendations also apply to teaching formal methods other than probability theory.
Ebenacobius Haran, a new southern African genus of flower weevils (Coleoptera: Curculioninae: Derelomini) associated with dicotyledonous plants

Published: May 2022

A new genus of derelomine flower weevil (Curculionidae: Derelomini sensu Franz 2006), Ebenacobius Haran gen. nov., is described to accommodate a clade of species morphologically and phylogenetically distinct from other genera in this tribe. This genus can be diagnosed as follows: protibiae armed with an apical mucro, claws free, eye convexity exceeding the contour of head in dorsal view and forehead with a median furrow. In total, 19 species are recognized in this genus; 14 species are described as new (E. curvisetis Haran gen. et sp. nov.; E. duplicatus Haran gen. et sp. nov.; E. grobbelaarae Haran gen. et sp. nov.; E. hessei Haran gen. et sp. nov.; E. hippopotamorum Haran gen. et sp. nov.; E. kuscheli Haran gen. et sp. nov.; E. mulanjensis Haran gen. et sp. nov.; E. oberprieleri Haran gen. et sp. nov.; E. rectirostris Haran gen. et sp. nov.; E. san Haran gen. et sp. nov.; E. pedi Haran gen. et sp. nov.; E. thoracicus Haran gen. et sp. nov.; E. tsonga Haran gen. et sp. nov. and E. xhosa Haran gen. et sp. nov.), five species of Derelomus Schoenherr (D. atratus Hesse; D. costalis Fåhraeus; D. incognitus Hesse; D. rhodesianus Hesse; D. turneri Marshall) are hereby transferred to Ebenacobius gen. nov. and one species name is placed in synonymy (Derelomus rugosicollis Hesse, 1929 = Derelomus costalis Fåhraeus, 1844 syn. nov.). Members of Ebenacobius gen. nov. seem to develop in inflorescences of dicot plants, with larval stages of at least two species recovered from the flowers of Euclea species (Ebenaceae). A key to the continental African genera of Derelomini and to species of Ebenacobius gen. nov. is provided. Pictures of habitus and terminalia of adults, along with distribution and life history data are also provided for each species.
Biopsy-Integrated 3D Magnetic Resonance Imaging Modeling of Prostate Cancer and Its Application for Gleason Grade and Tumor Laterality Assessment
Authors: Kim Jisup , Lim Bumjin , Jeong In Gab , Ro Jae Y. , Go Heounjeong , Cho Yong Mee , Park Kye Jin
Published: May 2022

Context.—

Grade Group assessed using Gleason combined score and tumor extent is a main determinant for risk stratification and therapeutic planning of prostate cancer.

Objective.—

To develop a 3-dimensional magnetic resonance imaging (MRI) model regarding Grade Group and tumor extent in collaboration with uroradiologists and uropathologists for optimal treatment planning for prostate cancer.

Design.—

We studied the data from 83 patients with prostate cancer who underwent multiparametric MRI and subsequent MRI–transrectal ultrasound fusion biopsy and radical prostatectomy. A 3-dimensional MRI model was constructed by integrating topographic information of MRI-based segmented lesions, biopsy paths, and histopathologic information of biopsy specimens. The multiparametric MRI–integrated Grade Group and laterality were assessed by using the 3-dimensional MRI model and compared with the radical prostatectomy specimen.

Results.—

The MRI-defined index tumor was concordant with radical prostatectomy in 94.7% (72 of 76) of cases. The multiparametric MRI–integrated Grade Group revealed the highest agreement (weighted κ, 0.545) and a significantly higher concordance rate (57.9%) than the targeted (47.8%, P = .008) and systematic (39.4%, P = .01) biopsies. The multiparametric MRI–integrated Grade Group showed significantly less downgrading rates than the combined biopsy (P = .001), without significant differences in upgrading rate (P = .06). The 3-dimensional multiparametric MRI model estimated tumor laterality in 66.2% (55 of 83) of cases, and contralateral clinically significant cancer was missed in 9.6% (8 of 83) of cases. The tumor length measured by multiparametric MRI best correlated with radical prostatectomy as compared with the biopsy-defined length.

Conclusions.—

The 3-dimensional model incorporating MRI and MRI–transrectal ultrasound fusion biopsy information easily recognized the spatial distribution of MRI-visible and MRI-nonvisible cancer and provided better Grade Group correlation with radical prostatectomy specimens but still requires validation.
Endometrial Polyp in Postmenopausal Women: An Epicenter for the Development of Endometrial Serous Carcinoma
Authors: Hui Pei
Published: May 2022

Context.—

Endometrial serous carcinoma is well known for its high risk of extrauterine spread, even when the intrauterine tumor is minimal in volume and limited to the endometrium. Representing the earliest recognizable forms of endometrial serous carcinoma, minimal uterine serous carcinoma (MUSC) includes serous endometrial intraepithelial carcinoma and superficial serous carcinoma.

Objective.—

To discuss the pathogenetic relationship between MUSC and endometrial polyp, and to review the pathologic diagnosis and clinical implication of MUSC.

Data Sources.—

Sources are a literature review and the author's personal practice and perspective.

Conclusions.—

A close topographic relationship between MUSC and endometrial polyp has been consistently observed in many studies: more than two-thirds of MUSCs involve an endometrial polyp and >50% of MUSCs are confined to an endometrial polyp at the time of staging hysterectomy, indicating that most if not all MUSCs arise in an endometrial polyp. Timely diagnostic recognition of MUSC is clinically critical because the patients without extrauterine tumor spread have an excellent prognosis and those with extrauterine involvement have a dismal outcome. Further investigations into the endometrial polyp harboring MUSC may elucidate the key cellular and molecular alterations underpinning the pathogenesis of uterine serous carcinoma.

La Prehistoria en los medios publicitarios: el uso comercial de la distorsión del pasado
Authors: Díaz de Torres María , Espinosa Soto Óscar Iván
Published: May 2022

La prehistoria no es una etapa de la historia ajena al gran público. Sin embargo, a pesar de los avances en la investigación prehistórica y las acciones divulgativas, la prehistoria se sigue representando bajo fuertes estereotipos y clichés.El presente trabajo analiza la visión social de la prehistoria y lo prehistórico a través del estudio de catorce piezas publicitarias audiovisuales de temática prehistórica. El estudio se ha hecho en base a cuatro líneas de análisis: el concepto de prehistoria, la imagen del entorno, la humanidad prehistórica y los comportamientos asociados a la prehistoria; lo que permite obtener una aproximación al imaginario colectivo y las distorsiones presentes en la sociedad sobre la prehistoria y lo prehistórico.
Flexible Learning Itineraries in Digital Environments for Personalised Learning in Teacher Training
Authors: Pérez-Garcias Adolfina , Tur Gemma , Villatoro Moral Sofia , Darder-Mesquida Antonia
Published: May 2022

The pedagogical strategy of flexible learning itineraries in digital environments aligns with current practices that focus on students’ agency to control their own learning. Flexible learning itineraries allow personalised learning while enhancing self-regulated learning skills such as setting aims and defining strategies. Paramount for successful strategies of flexible learning itineraries is the learning design which has to be defined with precision and responds to a detailed set of needs beyond access at anyplace or anytime. The main aim of flexible learning itineraries is to allow student choice so that they may construct their own pathway by selecting their options based on their own individual needs, motivations and prior knowledge. This research seeks to validate the prototype of a pedagogical strategy based on flexible learning design implemented in a subject of the Teacher Education programme at the University of the Balearic Islands. From a design-based research methodological approach, learning itineraries and sequences were created, and data was collected on student satisfaction via an online survey. Results show, on the one hand, the students' satisfaction with the experience and the pathways built, and on the other hand, in view of the diversity of choices made, that the pathways promoted the personalisation of learning, allowing the teaching-learning process to be adjusted to their personal characteristics. Conclusions suggest that the instructional design supports self-regulated learning strategies. In addition, conclusions reflect on the need to address digital current challenges from equitable and just approaches; and, also, on the value of the teacher's role as designer.
Implications of Message Length and Delay in Undergraduate Online Discussions

Published: May 2022

This study aimed at verifying the association of message length and delay in university online discussions with academic achievement and students’ influence on their classmates. Forums in Moodle were designed, and asynchronous online discussions with first-year undergraduate students of Educational Sciences were conducted. We gained word count from the learning management system, the weekly delay in posting a message to the forum was regarded, and we assumed the students’ grades to know their academic success. To obtain an indicator of influence, we conducted a social network analysis from the interactions that emerged from the online discussions. Then, we calculated the eigenvector centrality of each student once the debate had been completed. Results showed a low monotonic association between grades and the message words or the delay in posting. There was a slight trend to achieve more eigenvector centrality since students took more time to send a message and when messages were more synthetic. However, we did not obtain values in the coefficients that would allow us to infer a relevant association. The level of correlation detected for the grades was significant and, above all, regarding eigenvector centrality. We discussed the limitations of this study, the need for more research, and the implications for educational practice.
A Threshold for Citizen Science Projects: Complex Thinking as a Driver of Holistic Development
Authors: Sanabria-Z Jorge Carlos , Molina Espinosa José Martín , Alfaro Ponce Berenice , Vycudilíková Outlá Martina
Published: May 2022

Emerging technologies and community empowerment have driven citizen science (CS) projects. However, their impact remains vague, partly because of the difficulties in monitoring and standardizing these projects. Notably, the development of citizens' complex thinking is not among the primary goals, despite the connection with the tenets of Education 4.0 and the training of socially committed citizens. Therefore, we propose a framework and typology to foster CS projects while scaling up complex thinking. We used the evidence-based educational innovation (EBEI) methodology and the Theory of Change (ToC) perspective, reviewing some of the most relevant frameworks under UNESCO's Open Science Recommendation. Findings from the CS projects analysis revealed that: (a) there is inattention to developing the sub-components of the complex thinking macro-competency; (b) a growing trend to develop frameworks for CS projects is taking place; (c) there is a prevalence of CS project frameworks focused on prevention and control, project evaluation and design, and education and research; (d) a framework with three dimensions based on ToC (Outbound, Threshold and Full-cycle) can guide the development of CS projects; and (e) an eight-component typology can measure the progress and impact of CS projects from the perspectives of Context-awareness, Citizen engagement, Infrastructure leverage, Technological innovation, Educational innovation, Outreach and Scale, Network building, and Complex Thinking. We envision that the integrated framework and typology proposed, scaffolded by complex thinking, can comprehensively broaden the impact of CS initiatives.
La création de rétronymes dans le lexique de l'enseignement à l'heure du numérique
Authors: Zollo Silvia Domenica
Published: May 2022

In this contribution, we propose to study a specific typology of secondary lexical creation – retronymy – a lexicogenetic mechanism consisting in the relexicalisation of an already existing object and/or concept, following the appearance of a conceptual and formal neologism to which it is semantically linked. To do this, we first propose a theoretical framework of the phenomenon and then move on to an analysis based on the diachronic exploration (short diachrony) of the lexicon of education in relation to ICT, using the web corpus. The use of corpora will allow us to track and graphically capture lexical change by means of frequency distribution curves of lexical units belonging to the chosen domain. It will also allow us to empirically test the validity of the theoretical principles that, according to our hypothesis, support the mechanism of retronymic creation, as well as to offer a model of the prototypical profile of retronyms.

Dans cette contribution nous proposons d’étudier une typologie particulière de création lexicale secondaire– la rétronymie– un mécanisme lexicogénétique qui consiste dans la relexicalisation d’un objet, d’un concept déjà existant, suite à l’apparition d’un néologisme conceptuel et formel avec lequel il est sémantiquement lié. Pour ce faire, nous proposons tout d’abord un encadrement théorique du phénomène pour passer, ensuite, à une analyse basée sur l’exploration diachronique (diachronie courte) du lexique de l’enseignement à l’heure du numérique, à partir du corpus Web. L’utilisation de corpus nous permettra de suivre et de saisir graphiquement le changement lexical au moyen de courbes de distribution de fréquence des unités lexicales appartenant au domaine choisi. Cela nous permettra également de tester empiriquement la validité des principes théoriques qui, selon notre hypothèse, soutiennent le mécanisme de création rétronymique, ainsi que d’offrir une modélisation du profil prototypique des rétronymes.
Au fil de la pandemie de Covid-19, entre mots et termes
Authors: Jacquet-Pfau Christine
Published: May 2022

The Covid-19 pandemic has triggered an unprecedented coining of new words, many of which have been included in the general language dictionary Le Petit Larousse illustré. We will focus our study on the ways in which the dictionary has coped with this influx, paying close attention to one of the specific aspects of this neology, i.e. the way words shift from language of special purposes to language of general purposes and how the two of them overlap. It turns out that the interplay between public health, politics and society has created a vocabulary shared by both specialists and non-specialists. Le Petit Larousse illustré 2022 gives an insight into what could be considered the trade-mark of this lexical evolution and illustrates the transformation of the speakers’ attitude towards the language they have in common.

La crise de Covid-19 a suscité une néologie lexicale inédite dont le dictionnaire d’usage Le Petit Larousse illustré s’est très vite fait l’écho. Nous nous intéressons ici aux principales modalités selon lesquelles s’est faite cette évolution lexicographique, en accordant une attention particulière à un des aspects spécifiques de cette néologie: les transferts ou recoupements entre la langue courante et la langue spécialisée. En effet, les liens entre les contextes sanitaire, politique et sociétal ont en quelque sorte favorisé la création d’un vocabulaire commun aux spécialistes et aux profanes. Le Petit Larousse illustré 2022 permet d’analyser, sur un petit corpus, ce que l’on peut considérer comme la «marque de fabrique» de cette évolution mais aussi comme une transformation de la relation des locuteurs à une langue partagée.

Published: May 2022

O presente estudo visa descrever anatomicamente o tubo digestório da espécie Leporinus taeniatus. Foram utilizados 10 exemplares da espécie, coletados em diferentes trechos da bacia hidrográfica do Rio de Ondas, localizada no oeste do estado da Bahia, na ecorregião aquática do Rio São Francisco. Os peixes foram mensurados e pesados, sendo analisados e descritos a cavidade bucofaríngea e os órgãos digestórios pós-faríngeos: esôfago, estômago, cecos pilóricos e intestino. Para a definição do tamanho dos órgãos da espécie, independentemente do tamanho do exemplar, calculou-se o comprimento relativo dos órgãos, exceto dos cecos pilóricos. O L. taeniatus possui boca subterminal, fenda bucal com pequena amplitude, dentes incisiformes; esôfago curto e com tecido muscular pouco espesso; estômago sifoide, com formato em “J”, curto e pouco musculoso; seis a 14 cecos pilóricos evaginados no intestino; e intestino longo, com tecido muscular pouco espesso e disposto no formato de “N”. O estudo permitiu inferir que a espécie L. taeniatus possui hábito alimentar onívoro, com tendência a herbívoro, e que o tamanho dos órgãos do tubo digestório não está diretamente relacionado ao tamanho do exemplar. Dados obtidos no presente estudo ampliam o conhecimento acerca das características anatômicas do tubo digestório do grupo dos peixes e o conhecimento biológico e ecológico do L. taeniatus.

Published: May 2022

O objetivo deste estudo foi avaliar as concentrações de cálcio (Ca), potássio (K), sódio (Na) e magnésio (Mg) na água e em peixes de rios da Região de Integração de Carajás, Amazônia Oriental. As coletas foram realizadas entre maio e junho de 2015, nos municípios de Parauapebas, Canaã dos Carajás e Marabá, no estado do Pará. Foram selecionadas 14 áreas para a obtenção de amostras de água e exemplares de peixes, totalizando 53 exemplares. A quantificação dos teores de Ca, K, Mg e Na foi obtida por espectrometria de emissão óptica de plasma acoplada indutivamente (ICP-OES). As correlações de Spearman foram calculadas entre o conjunto de macroelementos presentes nas águas superficiais e no músculo das espécies de peixe. Houve grande variabilidade nas concentrações dos macroelementos das águas superficiais das áreas analisadas. Nos peixes, as concentrações médias de Ca (mg kg-1) foram: piaus (4498,77) > curimatã (3281,17) > tambaqui (2826,74) > acará (2405,15) > piranha (2385,65). As concentrações de K (mg kg-1) foram: piranha (15953,6) > piaus (15239,6) > curimatã (13393,3) > tambaqui (13069,2) > acará (11593,9). O Mg (mg kg-1) foi de: piaus (1256,96) > piranha (1109,59) > acará (1102,58) > curimatã (1036,87) > tambaqui (1007,07). O Na (mg kg-1) foi de: piaus (2998,06) > tambaqui (2820,95) > piranha (2747,43) > acará (2711,95) > curimatã (2125,17). O rio Parauapebas possui concentrações mais elevadas de Ca, K, Mg e Na comparadas àquelas encontradas nos rios Igarapé Gelado e Tapirapé. Os peixes analisados absorveram níveis diferentes de macroelementos, na ordem de K > Ca > Na > Mg para todas as espécies analisadas. Sob mesma condição de habitat, o piau apresentou maior capacidade de absorver Ca, K, Na e Mg da água comparado ao curimatã. As concentrações de Ca no músculo dos peixes são influenciadas significativamente pelas concentrações de Ca na água dos rios.

Published: May 2022

A relação entre a ansiedade pré-competitiva e desempenho esportivo ainda encontra-se pouco explorada pela literatura científica, principalmente nas modalidades coletivas. Assim o objetivo do estudo foi analisar as respostas de ansiedade pré-competitiva e desempenho percebido em relação ao local de jogo em atletas de futsal. Foram avaliados 19 atletas do sexo masculino (20,64±3,93 anos de idade) de uma equipe de futsal em um jogo dentro e um jogo fora de casa. A ansiedade pré-competitiva foi avaliada pelo questionário Revised Competition State Anxiety Inventory-2 (CSAI-2R) antes de cada jogo e o desempenho percebido pela escala Likert (0 à 4) após cada jogo. Como principais resultados foram observados o tamanho de efeito moderado e incerto (unclear) entre as condições fora e dentro de casa para a ansiedade somática (TE=0,75; CL= -0,19; 1,62) e cognitiva (TE=0,70; CL=-0,23; 1,52).  Para a auto-confiança um efeito pequeno e incerto (TE=0,20; CL=-0,69; 1,70). A percepção de desempenho não diferiu entre os jogos (P=0,564). Conclui-se que o local de jogo afeta moderadamente nas respostas pré-competitivas de ansiedade somática e cognitiva, porém de maneira incerta. Essa variação nas respostas de ansiedade entretanto parecem não impactar diretamente nas respostas de desempenho desses atletas, sugerindo assim que o local de jogo pode ter efeito na ansiedade pré-competitiva, de maneira morada e sem um possível impacto na percepção de desempenho dos atletas.
Estilos de liderança de professores: percepções de crianças com e sem problemas de comportamento.
Authors: Stadler Susan Bobato , Batista Ana Priscila
Published: May 2022

A escola é um contexto social importante para o desenvolvimento de crianças, assim como as práticas educativas de professores. Este estudo avaliou a percepção de crianças consideradas com e sem problemas de comportamento por seus professores acerca dos estilos de liderança dos mesmos. Para tal, contou com 59 crianças de 4º e 5º anos do Ensino Fundamental de escolas públicas e 12 professores. Cada professor indicava quatro alunos, sendo duas crianças com problemas de comportamento (CPC) e duas sem problemas (SPC), e responderam, para cada uma, o instrumento Teacher's Report Form para confirmar a indicação. As crianças responderam ao Inventário de Estilos de Liderança de Professores. Os resultados mostraram que 55% do Grupo CPC e 60% do Grupo SPC identificaram seus professores como negligentes. Quanto ao controle coercitivo, 50% dos alunos de ambos os grupos classificaram como de frequência tendência a alto, 25% do Grupo CPC e 20% do Grupo SPC classificaram como alto.  Não foi encontrada nenhuma diferença estatisticamente significativas (P>0,05) entre os grupos. Conclui-se que o predomínio do estilo negligente relaciona-se a não sensibilidade de professores a diferentes repertórios, sendo capazes de identificar mas não de comportar-se de forma contingente e efetiva diante de crianças com e sem problemas de comportamento.
Saúde mental, arte e reabilitação psicossocial: problematização da produção acadêmica brasileira (2008-2018)
Authors: Hinkel Jaison , Diaz de Vivar y Soler Rodrigo
Published: May 2022

Neste artigo problematizamos ações de reabilitação psicossocial realizadas a partir da interface entre arte e saúde mental, considerando suas potencialidades e fragilidades. A partir da metodologia construtivo-interpretativa, analisamos 78 materiais adquiridos mediante consulta à Biblioteca Virtual em Saúde, ao Portal de Periódicos Capes e à Biblioteca Digital Brasileira de Teses e Dissertações, considerando o período de 2008 a 2018. Identificamos uma pluralidade de ações envolvendo diversas linguagens artísticas, compostas por diferentes atores sociais e em parceria com instituições e movimentos sociais. As potencialidades destas experiências revelam benefícios que extrapolam os limites terapêuticos e vislumbram o fortalecimento do protagonismo dos sujeitos, promovendo tecnologias transformadoras relacionadas ao cuidado, ao trabalho e à organização social. Estes benefícios também afetam os serviços de saúde mental e seus trabalhadores, bem como geram transformações no imaginário social referente a loucura. Entretanto, observamos algumas fragilidades relacionadas, especialmente, à lógica terapêutica e institucionalizada de algumas ações analisadas.
Neutrophilic urticaria with systemic inflammation (NUSI) following Pfizer–BioNTech COVID-19 vaccine
Authors: Mustafa Javaria , Malesu Rashi , Major Gabor
Published: May 2022

The Pfizer–BioNTech mRNA vaccine has shown excellent protection against the severity of COVID-19, yet adequate research on rare adverse events is lacking. Herein, we discuss the case of a 36-year-old female who had developed an urticarial polymorphous eruption, episcleritis, and inflammatory oligo-arthritis, in keeping with neutrophilic urticaria with systemic inflammation (NUSI), following the administration of Pfizer COVID-19 vaccine. Investigations for other dermatological and rheumatological conditions were unremarkable, while multiple skin biopsies were highly suggestive of a neutrophilic drug reaction. To gain symptom control, our patient required multiple weeks off from work and was treated with several immunosuppressive, anti-inflammatory, and analgesic agents. Further research with larger numbers is needed to identify adverse events more accurately, which will aid both in early diagnosis and prompt treatment for patients.
Weaving Language and Learning in Negotiating for Meaning
Authors: Garcia Regina Via
Published: May 2022

Achieving an understanding of interlocutors in an English classroom is essential in successful communication, learning, and second language acquisition. Through these interactions, interlocutors can negotiate meaning by changing the linguistic form, conversational structure, and message content, or all three. This qualitative content analysis research focuses on the interactions produced between teacher and student or between the students themselves with the use of Michael Long’s Negotiation for Meaning (NfM). The research, conducted in Compostela Valley State College Main Campus, involved five (5) sections of first-year college students enrolled in General Education 2 - Purposive Communication along with their respective instructors. Interactions throughout the class were recorded and then transcribed for further analysis. According to the findings, three (3) signals from NfM are primarily utilized to achieve meaning; comprehension check, clarification request, and confirmation check. These signals functioned in the interaction through eliciting understanding, correcting, probing, recalling, and clarifying. The most used signal was a clarification request, and the most used function of these signals is understanding. The findings suggest that the negotiation in the interaction mostly required previous utterances to be clarified and that the main goal of negotiation is to achieve comprehension of the meaning being negotiated.
Revisiting Employment Vulnerability Index Using Principal Component Analysis
Authors: Dalupo Glecil Joy , Garcia Gary
Published: May 2022

The share of workers in vulnerable employment is directly linked to the share of people living in poverty. The statement recalls why understanding the employment vulnerability index (EVI) of a nation based on the present situations is very relevant. In view of that, The International Labor Organization (ILO) designed a parameter to predict the possible increase or decrease of the employment vulnerability index. However, the said formula does not capture the general issue of employment vulnerability, specifically in terms of the principal component. Hence this study was purposely conducted to develop a unique formula in computing EVI as a form of resolution in the development of vulnerability indices using the Principal Component Analysis. The principal component analysis develops indicators of vulnerability in employment using the United Nations Development Program (UNDP) data. The results identified two principal components that determine 82.60% of the variance of Employment Vulnerability. The generated formula concludes that the Employment vulnerability index is a function of types of employment and unemployment rate. Types of employment included the employment in agriculture and employment in services, and the unemployment rate comprised of employment to population ratio, unemployment labor force, unemployment youth, and labor force participation. Further, types of employment should be given more emphasis when it comes to EVI Plan than unemployment rate hence, type of employment shows greater influence to EVI with 66.30% compared to unemployment rate with only 33.70%.

The major concern of this study is to identify the challenges of small and medium enterprises towards progress in Pulo in the City of Cabuyao, Laguna, the Philippines as assessed by the business owner- respondents. By understanding their challenges, it is expected to improve the competitiveness of SMEs, and that eventually, they will grow and expand their businesses. When it comes to the nature of the business, the service type is the most commonly used by the medium enterprise business-owners with the least capitalization of 11,000 and up and with a capacity of 11 years of business operations. They all agreed that they encounter some difficulties in availing of funds because of lots of requirements in loan applications for business. They are also amenable to growing stiff competition that arises among the unregistered enterprises because of much cheaper offered products to the market. In this case, some SMEs have failed to compete with the micro-businesses. They all disagree on the perception that the focus on giving support is intended only for micro-enterprises, same as the LGU for the insufficient fund to support in promoting more the SME sector.

Authors: Hernandez Gloria , Dela Cruz Ramiro , Marucot Emmanuel
Published: May 2022

This study provides a framework for determining board exam probabilistic performances of students through the identification and analysis of indicators that affect student board exam performances. The design and development of the framework are governed by the theoretical and empirical study of factors related to student profiles, academic metrics, and academic support services metrics. The formulation of factors and considerations for the framework revolves around the identification of causal items affecting the board exam performance of examinees.  The factors are tested for their perceived causative and relational effects as drawn from related studies and literature. Moreover, this study provides a framework that addresses the issues related to managing board examination course offerings via consideration of university policies, practices, priorities, and programs.

La identificación de los pueblos indígenas en el Perú ¿Qué está sucediendo con el criterio de autoidentificación?
Authors: Alva Arévalo Amelia Isabel
Published: May 2022

Este artículo tiene como objetivo establecer que los parámetros legales para identificar a los pueblos indígenas en Perú limitan la aplicación del principio de autoidentificación. Para ello se examinan las normas internacionales sobre derechos humanos que consagran la autoidentificación como criterio fundamental. Luego, se explican los antecedentes de la terminología constitucional y legal para referirse a los pueblos indígenas en Perú, para entender por qué este tema se ha convertido en crítico. Finalmente, como consecuencia de la aplicación de la Ley de Consulta Previa y considerando el contexto extractivo, se discutirán los primeros obstáculos que algunas comunidades han enfrentado para ser considerados pueblos indígenas.

La cuestión de la dignidad en los mundos indígenas
Authors: Sanchez De Jaegher Carolina
Published: May 2022

La creciente disociación que se percibe de la humanidad con su casa común (la Tierra), se ha convertido en un terreno filosófico poroso y diverso, que por primera vez y después de largos siglos, reflexiona sobre su posición y nos da la oportunidad de desplazar al antropo-conocedor que hizo de la conquista de la naturaleza el fundamento de su posición privilegiada. Es esta base coyuntural la que también ha permitido la emergencia del conocer y sentipensar la dignidad sin el antropos como 'un fin en sí mismo', o, mejor dicho, no sólo en su contra (De la Cadena, 2019, p. 478; Kant, 1996). Dado que dignitas hominis es predominantemente un concepto occidental antropocéntrico, repensarlo sin la humanidad, o sin las racionalidades hegemónicas que han constituido su sustancia antropocéntrica y universalista, requiere de un diálogo con las múltiples éticas de la Tierra, particularmente con las éticas de esos mundos que nunca han aceptado la división colonial entre la vida humana y la no-humana: los mundos indígenas. En un momento de urgencia cuando los derechos humanos son frágiles a escala mundial, la problematización de la dignidad en este artículo comienza con su reposicionamiento como una invitación ontológica. Hacer referencia a la dignidad como tal tiene algunas consecuencias metodológicas, una de ellas es la posibilidad de desacoplar este valor de su sentido puramente antropocéntrico para fomentar un diálogo intercultural de múltiples dignidades. En segundo lugar, al reforzar el locus enuntiationis y las prácticas desde las cuales se defiende la naturaleza y la dignidad, se abre un canon para la pluriversidad en "mundo donde quepan muchos mundos" (Ejército Zapatista de Liberación Nacional [EZLN], 1997). 20 En la puerta de entrada de una comprensión del mundo que supera con creces la comprensión occidental de él y el reconocimiento de que la experiencia cognitiva de las éticas de la Tierra es extremadamente diversa, este artículo problematizará la idea de dignidad en el paradigma de la universalidad (Guilherme y Dietz, 2017; Merali, 2014; Mignolo, 2011; Quijano, 2000).
