Authors: Cláudio Machado João , Barreira Daniel , Teoldo Israel , Serra-Olivares Jaime , Góes Alberto , José Scaglia Alcides
Published: April 2021

This study aimed to investigate: i) how Small-Sided and Conditioned Games based on different representation and exaggeration modification strategies, from the Teaching Games for Understanding pedagogical principles, affected team performance and exploratory behaviour; and ii) how teams and players of different ages and skill levels were affected by the use of these different modification strategies. In total, forty-eight youth male soccer players participated in the study (U15, n = 24 mean age = 13.06 ± 1.53 years; U17, n = 24 mean age = 16.89 ± 0.11 years). In both categories, players were organized into three groups according to their tactical efficiency level (Group 01 = High Skilled Players (HSP), Group 02 = Intermediate Skilled Players (ISP), and Group 03 = Low Skilled Players (LSP)). The HSP and LSP groups performed two types of Gk+4vs4+Gk Small-Sided and Conditioned Games (SSCGs) based on different representation and exaggeration modification strategies. The first type of SSCGs was modified by structural constraints (Structural SSCG) and the second type was modified by rule manipulation (Manipulation SSCG). Team performance and exploratory behaviour were analysed through the Offensive Sequences Characterization System and Lag Sequential Analysis, respectively. SSCG modification strategies affected differently tactical performance and exploratory behaviour of teams composed of players of different skill levels. It was found that SSCG modification strategy through rule manipulation provided players and teams with a higher level of difficulty, compromising their performance and inhibiting exploratory behaviour. This information is crucial to practitioners wishing to apply more appropriate pedagogical strategies to improve a specific tactical problem using a player-centred and game-based approach.

Published: April 2021

The main aim of this study was to establish game-related statistics that determined sport results in the Basketball EuroLeague between 2003 and 2016. The study encompasses matches played by 10 teams during 13 consecutive seasons of the EuroLeague. Twenty-two offensive and defensive game related variables were registered. Calculations were performed to establish which of the variables determined performance in the Basketball EuroLeague matches within the analysed period. Based on a number of mathematical and statistical analyses, the elements of play that had the highest effect on sports success were selected. The following determinants displayed the most significant correlations with sport results in the EuroLeague within the analysed period: two-point shots made (2PT-made), two-point shot attempts (2PT-attempts), three-point shots made (3PT-made), one-point shots made (1PT-made), one-point shot attempts (1PT-attempts), assists, fouls and field goals made. The game outcome in basketball is influenced by many variables which may not always be significant in a given match. However, the continuous effort to maintain these variables at the highest possible level is advantageous over less-organised teams.
Fabrication of color conductive inks by introducing SWCNT/Ag and various dyes into polymeric solutions for potential applications in disposable, cheap, and flexible electronics
Authors: Zadeh Mohammad Hassan Ramezan , Seifi Majid , Mousali Ebrahim
Published: April 2021

The multifaceted field of conductive inks is moving from a preliminary to an advanced stage. In this study, cellulose filter paper was used as a popular, renewable, and inexpensive material, with very interesting flexible characteristics. The novelty of this work was to use a single-walled carbon nanotube/silver (SWCNT/Ag) nanopowder in a color polymeric matrix for preparing highly conductive color inks resistant to washing. An investigation comparing three inks colored separately with different anionic and cationic dyes was performed to examine possible changes in electrical resistivity of the papers. The results obtained from FT-IR spectroscopy showed the presence of carboxylic groups in acid-treated SWCNTs and revealed Ag-containing bonds. XRD results confirmed functionalization of SWCNTs and obtaining SWCNT/Ag powder with Ag nanoparticles (NPs). Thermal stability and degradation of specimens were studied using TGA analysis to measure the percentage of Ag NPs in the SWCNTs network. The TEM micrographs were consistent with the Scherrer results. Finally, different color inks were synthesized with/without SWCNT/Ag nanopowder, and the four-point probe technique was utilized to measure the electrical resistivity of each colored paper. Consequently, preparation of color conductive inks by using ultra-narrow SWCNTs was done successfully.

Published: April 2021

In this research work, polymer coated magnetic nanoparticles were prepared by co-precipitation method. The samples were characterized by XRD, SEM, EDS, VSM and two probe DC conductivity measurements. XRD pattern indicated the existence of a sole cubic phase of Fe3O4 with Miller indices (2 2 0), (3 1 1), (5 1 1), (4 4 0). An average size of magnetic nanoparticles was about 22.9 nm and it was reduced to 21.3 nm and 19.4 nm after 1 wt. %. and 2 wt. % coating of PEG-6000, respectively. The morphology and size of the samples were investigated by scanning electron microscope (SEM). EDX spectra confirmed the coating of PEG on magnetic nanoparticles. Magnetic properties were examined by vibrating sample magnetometer (VSM). Saturation magnetization (M
s
) decreased as the concentration of PEG increased in the magnetic material. Electrical properties of uncoated and polymer coated Fe3O4 nanoparticles were studied by two-probe conductivity meter. This study concluded that the thermal flow of charge in polymer coated magnetic nanoparticles can be evaluated at micro and nano level.
Reductions of Consciousness. From Husserl to Churchland
Authors: Kowalska Małgorzata
Published: April 2021

The author juxtaposes two extreme approaches to the relationship between consciousness and the physical world: phenomenological-idealistic (represented by Edmund Husserl) and radically naturalistic (represented by Paul Churchland). These two positions are interpreted in terms of opposite if symmetrical types of reduction (on the one hand, the reduction of the world to a sense for consciousness, and on the other hand, the reduction of consciousness to an element of the physical world). They emerge as two ways of abstracting from the ambivalence of ordinary experience, in which consciousness and the physical world are both mutually entangled and non-identical with each other. In conclusion, the author argues that contemporary philosophy, which follows both the idealistic and the naturalistic path, fails to solve the problem of this relationship.
Cultural Humility Addressing Racism and Microaggression (CHARM)
Authors: Li Shujin
Published: April 2021

Introduction

Racism, discrimination and microaggressions experienced by underrepresented nursing students contribute to a loss of confidence, and feelings of sadness and anger.1,2,3 These experiences affect the students’ academic performance, and personal wellness. 1,2,3 There is a need for innovative and accessible resources that provide instruction and promote critical thinking regarding racism and microaggressions in the classroom and clinical setting. The aim of the CHARM project is to provide a toolkit for nursing students regarding how to respond safely and effectively to microaggressions.

Method

The use of eLearning and simulation games have successfully been used to provide education and problem-solving skills in healthcare when interacting with various groups of individuals. A group of seven nursing students are collaborating with faculty to develop an eLearning Toolkit and virtual simulation games (VSGs) focused on addressing racism and microaggressions.

Results

To date, the outline of a website that includes access to a pre-learning module and 5 VSGs have been designed.  The pre-learning module includes definitions and education regarding the 6-step method to responding to microaggressions.4,5 The VSGs immerse the players into various scenarios where they are provided with options on how to respond in clinical situations and the potential consequences of the response they choose.

 

Discussion

This project is a work in progress, and it is hoped that this project will support nursing students, so that they feel less alone. In addition, we hope to improve their confidence and provide resources in managing encounters where racism and microaggressions occur.
Investigating the species-specific association between anuran calling phenology and air temperature
Authors: Wong Samantha
Published: April 2021

Climate change has been associated in phenological shifts for a variety of taxa. Amphibians, specifically the order Anura (frogs and toads), are considered particularly vulnerable due to their sensitivity to anthropogenic and environmental change. Previous research has documented shifts in the timing of anuran breeding that can be attributed, in part, to climate change, with potential implications for reproduction, survival, and development. This study aims to investigate how air temperature is associated with anuran calling phenology. I will examine the temporal trends in spring and summer air temperature in a lake in northern Ontario, Canada. and quantify seasonal patterns of calling anuran species using acoustic monitoring over a four-month period. I predict that there will be interspecific variation in peak calling associated with air temperature. Additionally, I expect to find asymmetrical association between air temperature and anuran species’ calling behaviour – wherein prolonged breeding species will have a larger optimal temperature range for calling compared to explosive breeding species. The findings of this research will aid in future conservation and provide insight for management strategies of anurans in Canada in response to anticipated climate warming.
NKR-P1B Receptor Expression and Function in the Different Innate Lymphoid Cells of the Lung
Authors: Vajko Lucas
Published: April 2021

Group 2 innate lymphoid cells (ILC2) are the majority of ILCs in murine lungs at steady state. ILC2s are the main producer of type-2-cytokines, IL-4, IL-5, IL-9, IL-13, and amphiregulin, playing key roles in lung tissue homeostasis, airway responses to pathogens and allergens, and in cancer-related defenses. ILC functions are regulated by cell surface receptors. NKR-P1B is an inhibitory receptor, which recognizes C-type lectin-related protein (Clr-b) as its ligand. NKR-P1B is expressed on subsets of natural killer cells, ILC2, ILC3, γδ T cells, macrophages and dendritic cells in a tissue-specific manner and regulates NK cell and ILC3 functions in the gut. Expression and function of NKR-P1B in the lung ILC populations is unexplored. Moreover, Clr-b, the ligand for NKR-P1B, is expressed in the bronchial epithelium, endothelial cells and in lung parenchyma, but its role in immune regulation in the lung is unknown. We hypothesize that ILC2s in the lung express NKR-P1B, and their function is regulated by the NKR-P1B:Clr-b recognition system. Using wild-type (WT) and NKR-P1B-deficient mice, we study the expression of NKR-P1B on lung ILC2, and the function of NKR-P1B:Clr-b recognition system in ILC2 development and function. We compare the phenotype, frequency, numbers and cytokine production by ILC2s upon stimulation between WT and NKR-P1B-deficient mice using antibody staining and flow cytometry analysis. This study will reveal the role of NKR-P1B as a model system for its human homolog, NKR-P1A, in the regulation of ILC development and function, advancing our understanding of how immune responses in the lung are regulated.
Fundamental Measurement: The Need Fulfilment Quality of Life (N-QOL) Measure
Authors: Langley Paul C. , McKenna Stephen P.
Published: April 2021

The quality adjusted life year (QALY) has serious problems related to its failure to adhere to measurement theory. If a QALY is to be meaningful, the utility score that translates time spent to an equivalent time spent in so-called perfect health must have ratio properties (i.e., it must support multiplication). Multiattribute utility scores (e.g. those generated by the EQ-5D-5L) fail to meet this standard. The multiattribute instruments produce ordinal scores that lack a true zero and they generate negative values. The manifest deficiencies of multiattribute utility instruments render them unfit, not only as a measure of therapy response but also in generating QALY claims. After 30 years of belief in their use, utilities and QALYs are clearly analytical dead ends.
 
The purpose of this commentary is to demonstrate a coherent way forward in health technology assessment by focusing, not on clinical attributes as surrogates for quality of life, but on measures that are based on a conceptual model describing patient value in terms of need-fulfilment. Building on an extensive, yet often overlooked literature, need-based measures that fit Rasch Measurement Theory criteria are converted from ordinal scores to interval scores to evaluate response to therapy. These measures meet the requirements of single attribute fundamental measurement which is the standard in the physical sciences. It is proposed that a translation from a Rasch interval scale (defined by logits) can be transformed to a bounded ratio scale. Need based Quality of Life (N-QOL) scales bounded by 0 (where no needs are fulfilled) to 1 (where all needs are fulfilled) form such scales. The N-QOL supports the full range of arithmetic operations. Multiattribute utilities and mathematically invalid QALYs can be put to one side as unfortunate historical curiosities in favor of a disease or target population specific N-QOL scale. Such a scale has the required properties to evaluate disease specific response to therapy This can also support N-QOL adjusted life years with a need- fulfillment life year (NALY) metric with ratio properties.

A TUTELA PROCESSUAL DO NASCITURO: O CONFLITO DE INTERESSES À LUZ DA TEORIA CONCEPCIONISTA
Authors: Silva Luciana Ferreira da , Iocohama Celso Hiroshi
Published: April 2021

O estudo, por meio de revisão bibliográfica e interpretação do sistema processual, trata de uma lacuna quanto a legitimidade processual do nascituro, quando ocorre conflito de interesses entre este e os seus genitores. Ao averiguar doutrinas relacionadas ao nascituro, bem como à luz da teoria concepcionista, observa-se que aquele que há de nascer é sujeito de direitos, portanto, considerado pessoa. Tomando como premissa os direitos fundamentais, o direito à vida está elevado ao patamar de condicionante dos demais direitos. Deste modo, é imprescindível que o nascituro durante as alegações, por parte de seus genitores para a interrupção da gravidez, tenha a possibilidade de exercer a ampla defesa e o contraditório. Entretanto, verifica-se que o nascituro não possui “voz” dentro do processo, já que este não é representado, ensejando afronta ao princípio do devido processo legal, visto que ninguém poderá ser privado de seus bens sem o devido processo legal. Ao retratar o descaso frente à igualdade material do processo, e ao observar o inciso I, do art. 72 do Código de Processo Civil, conclui-se que a intervenção do curador protege a igualdade material e processual, já que o curador especial será nomeado ao incapaz quando o seu interesse não for o mesmo de seus genitores, possibilitando que este possa configurar como parte do processo, resguardando os princípios constitucionais e processuais.

Published: April 2021

A construção de um conceito jurídico ao Acesso à Justiça é importante para sua compreensão, assim, evitando a utilização do termo sem critérios ou como uma expressão vaga. Identificou-se na pesquisa duas perspectivas, uma jurídico-processual, atrelada à efetividade do processo como instrumento de resolução de conflitos, e outra democrático-institucional, ligada ao papel do sistema jurídico e da instituição judiciária em regimes democráticos. Importante, também, as concepções de Acesso à Justiça como Acesso ao Poder Judiciário e Acesso aos Direitos, observando-se, neste sentido, uma dinâmica do Acesso à Justiça na relação entre o Acesso ao Judiciário e o Acesso aos Direitos. Em uma dimensão jurídica o Acesso à Justiça foi conceituado como direito humano e fundamental, podendo ser positivado ou implícito no ordenamento jurídico. Na fase de tratamento de dados utilizou-se o método cartesiano. O texto foi composto sob a base lógica dedutiva-indutiva.

Published: April 2021

BACKGROUND: Stomal mucocutaneous separation (SMS) is a serious and common short-term and long-term complication of ostomy surgery, but optimal methods to help prevent it have not been established. The authors hypothesized that seromuscular-dermal (SM-D) suturing may be better than all layer-dermal (AL-D) suturing to help prevent SMS. METHODS: This retrospective study evaluated the short-term SMS rate of patients who underwent colostomy or ileostomy surgery between 2015 and 2019. Patient demographics, medical and surgical history variables, as well as SMS outcomes were abstracted. Postoperative SMS severity was categorized by extent as follows: grade A (mild), grade B (moderate), and grade C (severe). RESULTS: In total, 105 patients (AL-D group, 45 patients; SM-D group, 60 patients) were enrolled in the study. SMS occurred in 24 patients (23%). The overall SMS rate was 18% (n = 11) in the SM-D group and 29% (n = 13) in the AL-D group (P = .202). The occurrence of severe (grade C) or moderate and severe SMS (grades B + C) in the SM-D compared with the AL-D group was significantly different (2% vs 16% [P = .011] and 10% vs 24% [P = .047], respectively). A history of steroid use was a risk factor for moderate and severe SMS (P = .016, odds ratio 5.694). Stomal height ≤1 cm was a a risk factor for all cases of SMS (P = .037, odds ratio 2.650). AL-D suture technique and a history of steroid use were independent risk factors for severe and moderate plus severe SMS (P = .021, odds ratio 12.844 and P = .027, odds ratio 4.808, respectively). CONCLUSION: In this study, use of the AL-D suturing technique and a history of steroid use were independent risk factors for the short-term development of moderate or severe SMS. Patients whose stoma was secured using the SM-D technique had a significantly lower rate of moderate or severe SMS.

Carbon stock is carbon stored both on the ground and land surface as plant biomass, dead plants (necromas), and in soil as soil organic matters. Change in carbon form becomes the basis for calculating emissions, where most of the carbon (C) elements that broken down into the air are usually bound to O2 and become CO2. Deforestation and degradation are the main threats on forest conservation in Indonesia. Deforestation and forest degradation that occur in Indonesia has led to the development of issues as a significant contributor to carbon emissions. The purpose of this study is to estimate carbon stocks in protected area at PT. Muara Sungai Landak Mempawah Regency, West Kalimantan Province. This study used non-destructive sampling. This method, was done by measuring the diameter of the tree and then using an allometric equation that is suitable for estimating biomass. The making of sample plots in this study is stratified on land cover condition and systematic sampling. The results show that carbon stock for the entire area/cover of the protected area of PT. Muara Sungai Landak is 25.970.08 tons. The highest carbon was in old shrubland cover with total of 15.425.15 tons, followed by young thicket 10.356.46 tons C. The smallest stock was in open peat land of 188.46 tons C. The calculation of vegetation in this study show the old shrub cover is 128.8 tons/ha.
