Self-Concept in Physical Education for Post-Pandemic School Health Improvement
Authors: Galán-Arroyo Carmen , Batista Da Silva Marco Alexandre , Rojo-Ramos Jorge 
Published: May 2024

Self-concept is one of the key aspects of personality development. It is relevant because it affects how a person sees him/herself and how he/she relates to others. During adolescence, self-perception tends to be highly variable due to the inherent changes of this stage, being a critical period in which to foster a healthy and confident personality. Add to this the critical circumstances experienced during the pandemic and it becomes a bombshell. Physical education classes, can promote the self-concept and improve school health. The aim of the study was to analyse self-concept in Spanish adolescents of physical education by sex, school location, age, educational level and body mass index (BMI) after the pandemic. A cross-sectional study of 961 students’ physical education classes in public schools in Extremadura (Spain) was obtained and administered the Self-Concept Questionnaire version 5 (AF-5). The results showed that there is an association between AF-5 and sex, where adolescent girls have lower self-concept; there is a slight inverse relationship between AF-5 with age and BMI and there is no significant association between AF-5 and school location. In conclusion, knowing the relevant factors of self-concept after covid allows the educational community to implement tools for the optimal development of self-concept in Physical Education students, thus performance of adolescents.
El autoconcepto es uno de los aspectos clave del desarrollo de la personalidad. Es relevante porque afecta cómo una persona se ve a sí misma y cómo se relaciona con los demás. Durante la adolescencia la autopercepción suele ser muy variable debido a los cambios inherentes a esta etapa, siendo un periodo crítico para fomentar una personalidad sana y segura. Si a esto le sumamos las circunstancias críticas vividas durante la pandemia, se convierte en un bombazo. Las clases de educación física, pueden favorecer el autoconcepto y mejorar la salud escolar. El objetivo del estudio fue analizar el autoconcepto en adolescentes españoles de educación física según sexo, localización escolar, edad, nivel educativo e índice de masa corporal (IMC) tras la pandemia. Se realizó un estudio transversal de 961 alumnos de clases de educación física de colegios públicos de Extremadura (España), a los que se les aplicó el Cuestionario de Autoconcepto versión 5 (AF-5). Los resultados mostraron que existe asociación entre AF-5 y el sexo, donde las adolescentes tienen un menor autoconcepto; existe una ligera relación inversa entre AF-5 con la edad y el IMC y no existe una asociación significativa entre AF-5 y la ubicación de la escuela. En conclusión, conocer los factores relevantes del autoconcepto post covid permite a la comunidad educativa implementar herramientas para el óptimo desarrollo del autoconcepto en los estudiantes de Educación Física y con ello del desempeño de los adolescentes.
DA UNIÃO ESTÁVEL E DO CONTRATO DE NAMORO NO ÂMBITO DO DIREITO DE FAMÍLIA BRASILEIRO
Authors: Soares de Oliveira Ingrid , Aguilar de Almeida Alisson , Silveira Soares Leonarde Geovana 
Published: May 2024

Atualmente, grande parte da sociedade brasileira acredita que o estabelecimento de uma relação duradoura é o bastante para caracterizar-se a união estável. Entretanto, com as mudanças legislativas, o principal requisito para que o instituto seja reconhecido passou a ser a intenção compartilhada e atual de fundar uma vida familiar. Nesse viés, o artigo 1.173 do Código Civil Brasileiro de 2002 abarca os requisitos necessários para a identificação de uma união estável, sendo estes: a convivência pública, contínua e com o propósito de construir uma família.

Dessa forma, em um relacionamento em que não exista o desejo de constituir família, ou em que a intenção seja apenas futura, não há o que se falar em união estável, uma vez que não existe a principal qualificação para a configuração do instituto. Todavia, segundo a expressão utilizada pela doutrina e também por uma decisão colegiada do STJ, pode-se chamá-lo de "namoro qualificado", que pode vir a ser resguardado pelo contrato de namoro. Isto posto, o presente artigo tem como objetivo discorrer acerca das diferenças entre estes dois institutos, abordando seus principais aspectos e características, assim como sua aplicabilidade na jurisdição brasileira.

Authors: Garba Adamu 
Published: May 2024

This research work examined the effect of product market matrix on the performance of medium enterprises in North Central, Nigeria. The researcher used primary data source from a sample of three hundred and eighty four (384) respondents obtained by the use of a structured questionnaire. The data collected was analyzed using descriptive statistics such as frequency, simple percentage and the relationship between the variables of the model were tested using multiple linear regression analysis. The hypotheses of the study were tested using the probability value of the regression estimates. The result of the regression analysis indicates that Market penetration strategy's regression coefficient is 0.401 and significant (p0.05). Product development strategy is -0.059 and negligible (p0.05). A one-unit increase in product development decreases medium firm performance by 0.059 units. A one-unit increase in market development strategy increases medium firm performance by 0.196 units (p0.05). Product diversification approach has a strong coefficient of 0.319. This means a one-unit improvement in product diversification strategy increases medium firm performance by 0.319 units. It was concluded that businesses must consider the region's market conditions, competitive hurdles, and client behaviors to flourish. It was recommended among others that Market Penetration and Product Diversification Strategies are advised for medium enterprises in North Central Nigeria due to their benefits. Expanding market share and targeting existing clients can increase performance. Diversifying products to fulfill client needs can enhance revenue and performance. Firms should use both methods to optimize profits.
PHARMACOLOGIC TREATMENT OF THE IRRITABLE BOWEL SYNDROME: A COMPREHENSIVE SYSTEMATIC REVIEW
Authors: Sijabat Landong , Novettiandari Guinanti 
Published: May 2024

Background: Abdominal pain and changes in stool frequency are two of the symptoms of Irritable Bowel Syndrome (IBS), a chronic gastrointestinal illness. As there is no known cure, treatment focuses on symptom management. Patients struggle with psychological and emotional issues that lower their quality of life. Clinical trials have demonstrated the therapeutic effects of several therapeutic drugs, which may improve GI symptoms and general quality of life. Effective treatment of IBS requires an understanding of the connection between pharmaceutical medicines and the illness.
Methods: Following PRISMA 2020 guidelines, this systematic review concentrated on full-text English literature published between 2014 and 2024. Editorials and review articles that appeared in the same journal as the submission were not accepted without a DOI. The literature was assembled using a variety of online databases, including ScienceDirect, PubMed, and SagePub.
Result: The study screened about 20.000 publications using reputable sources including Science Direct, SagePub, and PubMed. Seven papers were found to be pertinent for systematic investigation, after which the entire material was examined in more detail.
Conclusion: IBS treatment has shown significant improvement in patients with Minesapride, a novel 5-HT4 receptor agonist, and tenapanor. Tenapanor showed significant improvement in symptoms, treatment metrics, and satisfaction, while geraniol improved the inflammatory profile. Melatonin showed improvement in IBS score and GI symptoms, but no significant improvement in frequency of defecations per week. Amitriptyline showed effectiveness over placebo, while co-micronized PEA/PD improved IBS symptoms in children.

Abstract: This paper offers an exploration of the ethical implications surrounding power, gender, leadership, and change in leadership and coaching. This exploration delves into the dynamics of oppressive power structures with a specific focus on gender dynamics and their profound impact on our personal and professional lives. Through the lens of Shoukry’s Emancipatory Coaching framework (2016), we offer a strategy that can enable coaches to inspire transformative change within themselves and for their clients in the spirit of creating inclusive, safe, and equitable environments. The goal is to incite dialogue and reflection around what it means to shape a renewed commitment and approach to coaching in the context of today’s social challenges in a way that also drives positive social change.
Dancefloor, prédrink et after : la construction d’une oreille techno par l’expérience collective et le corps au sein de la scène techno montréalaise
Authors: Fortant Elsa 
Published: May 2024

Cet article, s’appuyant sur une enquête ethnographique menée dans le cadre de mon mémoire de maîtrise « Nouvelles perspectives sur la scène techno montréalaise : du populaire à l’underground, entre unité et cohabitation » (2022), a pour objectif de montrer comment les lieux fréquentés par les amateurs et amatrices de ce genre musical font socialisation et comment les moments, le « avant-pendant-après », s’articulent dans la construction d’une « oreille techno » par le corps et par l’expérience collective. Dans le cadre de ma recherche, j’ai diffusé un questionnaire auprès des amateurs et amatrices montréalais·es de techno sur Internet (n = 336 réponses) et j’ai réalisé 15 entretiens semi-dirigés. Cet exercice a permis aux répondant·es de revenir sur des moments vécus, faisant émerger un discours réflexif sur leur parcours d’amateur, d’amatrice, et leur « oreille techno ». Dans un premier temps, cet article démontrera que sur le dancefloor, la socialisation de l’oreille à la techno se fait principalement par le corps, où les danseurs et danseuses aiment être « dans leur bulle » pour déployer leur « corps-oreille » (Sayeux 2010). Dans un deuxième temps, je m’intéresserai à l’« avant » (prédrink au Québec) et à l’« après-soirée » (after) comme cadre d’appréciation de la musique techno. Bien plus que de simples extensions de la soirée sur le dancefloor, ces moments entre pair·es qui ont lieu avant et après la soirée participent à la socialisation de l’oreille à la techno, d’une part, en permettant un cadre favorable aux discussions et, d’autre part, en prolongeant l’expérience collective d’écoute de la musique.

Published: May 2024

New technologies and the needs of specific missions have allowed and stimulated the development of airplanes with great structural flexibility. In these vehicles, there is a significant coupling between aeroelastic phenomena and flight dynamics. This has been a topic of research in recent years. Different methodologies have been studied to model the complete dynamics of flexible aircraft. One of these is the NFNS_s methodology (Non linear flight dynamics, non linear structural dynamics, strain based formulation). This article presents the use of this methodology in the analysis of the aeroelastic response and flight dynamics of a transport category aircraft with high structural flexibility. The effects of the wing elastic axis and the flexural axis positions were analyzed. Trimming, calculus of eigenvalues and time-marching simulations were carried out and the results were analyzed in detail. Some results were compared with those published in the literature. Similar trends were observed. This served as a qualitative validation of the methodology used. Some limitations of the study are described. The contributions of this work lie in the use of the NFNS_s methodology to analyze the effects of the elastic and flexural axis positions. In addition, the results of time marching simulations of the airplane modeled and the analysis carried out in great detail are other important novelty.
Plasmonic Crystals: A Platform to Catalog Resonances from Ultraviolet to Near‐Infrared Wavelengths in a Plasmonic Library
Authors: Gao Hanwei , Zhou Wei , Odom Teri W. 
Published: December 2009

AbstractSurface plasmons are responsible for a variety of phenomena, including nanoscale optical focusing, negative refraction, and surface‐enhanced Raman scattering. Their characteristic evanescent electromagnetic fields offer opportunities for sub‐diffraction imaging, optical cloaking, and label‐free molecular sensing. The selection of materials for such applications, however, has been traditionally limited to the noble metals Au and Ag because there has been no side‐by‐side comparison of other materials. This feature article describes recent progress on manipulating surface plasmons from ultraviolet to near‐infrared wavelengths using plasmonic crystals made from 2D nanopyramidal arrays. A library of plasmon resonances is constructed in the form of dispersion diagrams for a series of unconventional and new composite plasmonic materials. These resonances are tuned by controlling both intrinsic factors (unit cell shape, materials type) and extrinsic factors (excitation conditions, dielectric environment). Finally, plasmonic crystals with reduced lattice symmetries are fabricated as another means to tailor resonances for broadband coupling.

AbstractChemical vapor deposition (CVD) polymerization utilizes the delivery of vapor‐phase monomers to form chemically well‐defined polymeric films directly on the surface of a substrate. CVD polymers are desirable as conformal surface modification layers exhibiting strong retention of organic functional groups, and, in some cases, are responsive to external stimuli. Traditional wet‐chemical chain‐ and step‐growth mechanisms guide the development of new heterogeneous CVD polymerization techniques. Commonality with inorganic CVD methods facilitates the fabrication of hybrid devices. CVD polymers bridge microfabrication technology with chemical, biological, and nanoparticle systems and assembly. Robust interfaces can be achieved through covalent grafting enabling high‐resolution (60 nm) patterning, even on flexible substrates. Utilizing only low‐energy input to drive selective chemistry, modest vacuum, and room‐temperature substrates, CVD polymerization is compatible with thermally sensitive substrates, such as paper, textiles, and plastics. CVD methods are particularly valuable for insoluble and infusible films, including fluoropolymers, electrically conductive polymers, and controllably crosslinked networks and for the potential to reduce environmental, health, and safety impacts associated with solvents. Quantitative models aid the development of large‐area and roll‐to‐roll CVD polymer reactors. Relevant background, fundamental principles, and selected applications are reviewed.
Laboratory monitoring of new anticoagulants
Authors: Castellone Donna D. , Van Cott Elizabeth M. 
Published: December 2009

AbstractMaintaining a balance between bleeding and clotting has always been a challenge in treating coagulation disorders. A perturbation in that balance can be associated with substantial morbidity and mortality. As a result, anticoagulant monitoring is extremely important, and inappropriate testing may lead to complications. There are now a variety of new anticoagulant drugs in clinical use including several direct thrombin inhibitors (DTIs), such as argatroban, bivalirudin, and hirudin, as well as a Factor Xa inhibitor, fondaparinux. There are pitfalls associated with some of the currently used laboratory monitoring tests, and newer alternative laboratory monitoring tests have been investigated (Walenga and Hoppensteadt, Semin Thromb Hemost 2004;30:683–695). In addition, laboratory testing can assist with transitioning patients from DTI to warfarin therapy. Am. J. Hematol. 2010. © 2009 Wiley‐Liss, Inc.
The standing neutral: A ‘real time’ resolution procedure that also can prevent disputes
Authors: Groton James P. 
Published: December 2009

AbstractBusiness needs to make more effective use of the standing neutral. The concept of a trusted neutral overseer isn't new, but it's not as well known as it should be, writes James P. Groton, of Atlanta. The mere presence of a standing neutral has an effect on the parties' negotiating stance—frequently heading off conflicts before they blow up. A sample agreement form is provided.
Catalytic Enantioselective Olefin Metathesis in Natural Product Synthesis. Chiral Metal‐Based Complexes that Deliver High Enantioselectivity and More
Authors: Hoveyda Amir H. , Malcolmson Steven J. , Meek Simon J. , Zhugralin Adil R. 
Published: December 2009

AbstractChiral olefin metathesis catalysts enable chemists to access enantiomerically enriched small molecules with high efficiency; synthesis schemes involving such complexes can be substantially more concise than those that would involve enantiomerically pure substrates and achiral Mo alkylidenes or Ru‐based carbenes. The scope of research towards design and development of chiral catalysts is not limited to discovery of complexes that are merely the chiral versions of the related achiral variants. A chiral olefin metathesis catalyst, in addition to furnishing products of high enantiomeric purity, can offer levels of efficiency, product selectivity and/or olefin stereoselectivity that are unavailable through the achiral variants. Such positive attributes of chiral catalysts (whether utilized in racemic or enantiomerically enriched form) should be considered as general, applicable to other classes of transformations.
Heterozygosity and mutation rate: evidence for an interaction and its implications
Authors: Amos William 
Published: December 2009

AbstractIf natural selection chose where new mutations occur it might well favour placing them near existing polymorphisms, thereby avoiding disruption of areas that work while adding novelty to regions where variation is tolerated or even beneficial. Such a system could operate if heterozygous sites are recognised and ‘repaired’ during the initial stages of crossing over. Such repairs involve an extra round of DNA replication, providing an opportunity for further mutations, thereby raising the local mutation rate. If so, the changes in heterozygosity that occur when populations grow or shrink could feed back to modulate both the rate and the distribution of mutations. Here, I review evidence from isozymes, microsatellites and single nucleotide polymorphisms that this potential is realised in real populations. I then consider the likely implications, focusing particularly on how these processes might affect microsatellites, concluding that heterozygosity does impact on the rate and distribution of mutations.
Legal, ethical, and methodological considerations in the Internet‐based study of child pornography offenders
Authors: Ray James V. , Kimonis Eva R. , Donoghue Christine 
Published: December 2009

AbstractWith its ever‐growing penetration of remote regions of the world, the Internet provides great opportunity for conducting research. Beyond clear advantages such as increased cost‐effectiveness and efficiency in collecting large samples, Internet‐based research has proven particularly useful in reaching hidden or marginalized populations who engage in illegal or deviant behaviors. However, this new medium for research raises important and complex legal, ethical, and methodological/technological issues that researchers must address, particularly when studying undetected criminal behaviors. The current paper chronicles various issues that were encountered in the implementation of an active Internet‐based pilot research study of child pornography (CP) users. Moreover, this study was undertaken to address a critical gap in the existing research on CP offending, which has to date primarily focused on incarcerated or convicted samples. The Internet provides the optimal medium for studying community populations of CP users, given that it has become the primary market for CP distribution. This paper is designed to serve as a guide for researchers interested in conducting Internet‐based research studies on criminal and sexually deviant populations, particularly CP offenders. Several recommendations are offered based on our own experiences in the implementation of this study. Copyright © 2009 John Wiley & Sons, Ltd.
Au Nanowire–Au Nanoparticles Conjugated System which Provides Micrometer Size Molecular Sensors
Authors: Kang Taejoon , Yoon Ilsun , Kim Jangbae , Ihee Hyotcherl , Kim Bongsoo 
Published: December 2009

AbstractWe report a new type of molecular sensor using a Au nanowire (NW)–Au nanoparticles (NPs) conjugated system. The Au NW–NPs structure is fabricated by the self‐assembly of biotinylated Au NPs on a biotinylated Au NW through avidin; this creates hot spots between NW and NPs that strongly enhance the Raman signal. The number of the Au NPs attached to the NW is reproducibly proportional to the concentration of the avidin, and is also proportional to the measured surface‐enhanced Raman scattering (SERS) signals. Since this well‐defined NW–NPs conjugated sensor is only a few micrometer long, we expect that development of multiplex nanobiosensor of a few tens micrometer size would become feasible by combining individually modified multiple Au NWs together on one substrate.
