Las emociones como factor vinculante entre el saber y el aprender: articulación del contenido curricular con el aprendizaje socioemocional en la escuela
Authors:   , Herrera Peña Marco Antonio
Published: October 2023

En nuestro país el desarrollo socioemocional no ha sido considerado como relevante por el sistema educativo (Milicic, et. al, 2020), olvidando sus fundamentos humanos y centrándose en asuntos instrumentales (Murillo, 2021), aun cuando es uno de los factores que beneficia los logros intelectuales (Céspedes, 2020) y mejora significativamente el clima de aprendizaje. Esta situación amerita la articulación del currículum para facilitar el transcurrir de los estudiantes en el sistema educativo (Azzerboni, 2005). A partir de la pregunta ¿Cómo los profesores articulan el currículum de su asignatura con la dimensión socioemocional de sus estudiantes? este estudio busca proponer estrategias de articulación curricular para el desarrollo de la dimensión socioemocional de los estudiantes en función del alcance de logros integrales. La investigación tiene un enfoque cualitativo fenomenológico. Para la recolección de información se utilizó la entrevista semiestructurada. Los resultados fueron sometidos al proceso de análisis temático donde se indagó en la trayectoria, memoria afectiva, vínculo educativo, emociones en educación y decisiones curriculares. Para concluir, se propone un plan de acción de dos fases que responden a las problemáticas identificadas: desconocimiento en educación socioemocional por parte de los docentes y desarticulación de la dimensión socioemocional con el contenido curricular. Finalmente se presenta un posicionamiento profesional que evidencia la pertinencia del plan de mejora en el contexto estudiado.
Diseño y validación de una escala tipo LIKERT para evaluar la actitud ambiental de estudiantes de primero y segundo medio de establecimientos educacionales chilenos
Authors:   , Baeza Retamal Felipe Andrés
Published: October 2023

En este estudio, se elaboró una escala tipo LIKERT de cuatro opciones para poder evaluar las actitudes ambientales que poseen los estudiantes que cursan los niveles de primero y segundo medio en el sistema nacional chileno de educación escolar. Para construir la escala, se siguió el modelo metodológico para la confección de escalas tipo Likert presentado por Blanco, Urosa y Morales (2003), mientras que las dimensiones teóricas del constructo, fueron definidas a partir del modelo teórico de la actitud ambiental Two Main Environmental Values (2-MEV) (Bogner, 1996). La versión inicial de la escala contuvo 60 enunciados asociados a las dimensiones de Preservación (PRE) y Utilización (UTL) definidas por el modelo 2-MEV. En el caso de la dimensión PRE los reactivos fueron formulados en base al modelo tripartito de la actitud descrito por Rosenberg y Hovland, (1960), mientras que en la dimensión UTL, se redactaron enunciados correspondientes a conductas de cuidado ambiental. La muestra de pilotaje está comprendida por un universo de 141 estudiantes, de los cuales un 53,2% corresponde a hombres mientras que un 46,8% son mujeres. En el análisis exploratorio, los resultados señalaron la conformación de tres factores que explican el 31,218% de la varianza. Los índices de bondad de ajuste RMSR y RMSEA resultaron adecuados para el modelo predicho. Adicionalmente se observaron buenos índices de dificultad y discriminación para los reactivos seleccionados para la confección de la escala definitiva, observándose un comportamiento similar en la confiabilidad del instrumento completo y sus sub escalas. Dado esto, el instrumento resulta válido y confiable para poder evaluar las actitudes ambientales de los estudiantes, aunque se requiere corroboración confirmatoria futura para poder validar el modelo de prueba escogido.
Concepciones sobre la evaluación de los formadores de pedagogía en matemática
Authors:   , Aros Pinochet Beatriz Soledad
Published: October 2023

En los últimos años la literatura a puesto más énfasis en las prácticas de enseñanza de los formadores (Schuck & Brandenburg, 2020), en comparación al estudio de las prácticas evaluativas que implementan los formadores en matemática. Esto genera falta de información sobre estas temáticas y este proyecto permitirá dar luces a este tema y abrir la discusión en torno a este. Es por ello, que este proyecto de Magíster busca identificar las concepciones de evaluación en los formadores de carreras de pedagogía en matemática por medio de un abordaje fenomenográfico, pues sus concepciones pueden influir en las posibles concepciones de los futuros docentes. Para ellos se realizaron siete entrevistas semiestructuradas a formadores pertenecientes a universidades acreditadas por el estado chileno. Se identificaron cuatro categorías de descripción: evaluación como medio para la certificación; evaluación como medio para la mejora de la enseñanza; evaluación como medio para el aprendizaje; evaluación como un proceso intrínseco en la enseñanza y aprendizaje, y tres dimensiones de variación de ellas: cómo se evalúa, para qué se evalúa y la preparación de la evaluación. En base a estos resultados se recomienda realizar cursos de desarrollo profesional docente en formadores de matemática en temas relacionados con evaluación, realizar acompañamiento al formador para la elaboración de las prácticas evaluativas e incentivar la reflexión y el trabajo colaborativo de los formadores sobre la evaluación y sus prácticas evaluativas.
Desafíos de las y los profesores, de un establecimiento particular subvencionado de la Región Metropolitana, con respecto a la evaluación formativa, retroalimentación y planificación integrada de la enseñanza y la evaluación, a partir del primer año de implementación del decreto N°67/2018
Authors:   , López Llanos Constanza
Published: October 2023

El presente estudio tuvo como propósito caracterizar los desafíos que presentaron los docentes de un establecimiento particular subvencionado de la Región Metropolitana al momento de implementar el decreto N°67/2018, tomando en cuenta aspectos como evaluación formativa, retroalimentación y planificación de la evaluación integrada a la enseñanza. Los datos para este estudio fueron obtenidos mediante entrevistas semiestructuradas a docentes de la institución, cuyos relatos fueron comparados con lo declarado por el reglamento evaluativo institucional y el nuevo decreto de evaluación. Los principales hallazgos de esta investigación tienen relación con los desafíos derivados de las preconcepciones docentes, puesto que guían el accionar de los profesores frente a una ausencia de lineamientos transversales al profesorado desde la institución, estas preconcepciones son deficientes en aspectos como la retroalimentación orientada a promover la autorregulación y el desarrollo del juicio evaluativo del estudiantado y la planificación de la evaluación integrando aspectos como el tiempo para retroalimentar y la diversificación de agentes evaluativos. Como proyección, se plantea el contraste de las preconcepciones docentes a lo largo de la implementación del decreto N°67/2018 de modo de evidenciar si la implementación de este decreto ha promovido un cambio dentro de las prácticas evaluativas del cuerpo docente.
Creencias de las y los profesores sobre la evaluación de estudiantes inmigrantes no hispanohablantes
Authors:   , Fuentes Toro Alex Ignacio
Published: October 2023

La presente investigación se focaliza en el análisis de las creencias que tienen los profesores y profesoras de aula al evaluar a estudiantes inmigrantes no hispanohablantes con la finalidad de propiciar una educación inclusiva. El estudio fue realizado bajo una metodología cualitativa y un enfoque constructivista, sustentado en la tradición fenomenológica. La recolección de datos se llevó a cabo mediante entrevistas semiestructuradas que fueron analizadas aplicando técnicas de microanálisis y codificación abierta. Los resultados de esta investigación permiten evidenciar que tanto las experiencias profesionales como las leyes y estrategias nacionales tienen una incidencia en las creencias de las y los profesores. Así pues, fue posible identificar que los usos de la evaluación formativa y sumativa son diversos y varían según el contexto y las decisiones que se toman. Finalmente, las creencias que predominan en los participantes no solo tensionan las nociones de diferencia, igualdad y desventaja, sino también los instrumentos de evaluación con intencionalidad sumativa, los cuales pasan a ser el foco fundamental de un proceso que se sigue percibiendo como excluyente del aprendizaje.

Authors:   , Venegas Yolanda C.
Published: October 2023

El texto escolar es un recurso frecuentemente usado para promover los aprendizajes de los estudiantes y para apoyar a los docentes en la planificación de la enseñanza y evaluación. Si bien los textos podrían favorecer la calidad de la enseñanza en áreas como Ciencia, poco se ha investigado sobre las tareas de aprendizaje y evaluación que los configuran y sus características. Este proyecto caracteriza tareas del texto escolar de Ciencias Naturales de 4º básico licitado por el Ministerio de Educación para el año 2020. Un total de 1011 tareas fueron segmentadas y codificadas en función de cuatro dimensiones: función didáctica, procesos cognitivos, tipos de respuestas y modos semióticos en instrucción y respuestas. Los resultados indican que la función didáctica predominante es la de aprendizaje (73,5%); mientras que en la dimensión de los procesos cognitivos la mayoría de las tareas de ciencias presentan procesos de baja complejidad (comprender 40,6% y recordar 22,6%). En cuanto a las instrucciones de las tareas prevalece el modo verbal (71,9%) y en las respuestas se solicita a los estudiantes responder con el modo verbal escrito (70,4%). Los resultados ofrecen información relevante para las política y prácticas pedagógicas de la asignatura de Ciencias.
Unveiling the architecture of the Fornax galaxy cluster with its different stellar systems
Authors:   , Órdenes Briceño Yasna
Published: October 2023

A crucial question in astronomy is how galaxies assemble their mass over cosmic time. In this thesis, we focus on the Fornax Galaxy Cluster as a laboratory to study galaxy evolution processes, as it is the second closest galaxy cluster which allows a detailed view of its cluster members. It hosts a variety of stellar systems from giant galaxies to dwarf galaxies and more compact and dense ones such as globular clusters and ultra-compact dwarf galaxies which we call compact stellar systems (CSSs). We use data from the Next Generation Fornax Survey (NGFS) with optical imaging obtained with the Dark Energy Camera (DECam) mounted at Blanco/CTIO and near-infrared data obtained with VIRCam at VISTA/ESO. This data provides deep and homogeneous photometry in u'g'i' JKs spatially covering the Fornax cluster out to half its virial radius. We investigate the properties of nucleated dwarf galaxies and compact stellar systems in the Fornax core region (r < 0.25rvir). Furthermore, we study the dwarf galaxy population with MB > −16 in the outer region of Fornax at radii of 0.25 < r/rvir < 0.5. The main results of this thesis are as follows: (1) We have discovered 271 previously undetected dwarf galaxies in the outer Fornax cluster region, increasing the total Fornax dwarf galaxy population from NGFS and other catalogs to a total number of 643 dwarfs with 181 being nucleated. (2) The study of 61 nuclear star clusters in dwarf galaxies showed that the nuclei have a bimodal mass distribution and that the scaling relation between nucleus mass and host galaxy mass holds for dwarf galaxies but at a less steep slope compared to brighter galaxies. The mass ratio Mnuc/Mgal shows a clear anticorrelation with Mgal for the lowest masses, reaching up to 10%. (3) A total of 1666 CSS candidates have been studied in the core region of Fornax, being the most clean photometrically selected sample using support vector machine techniques. Age, metallicity and mass were estimated for each CSS. A division of the properties in subgroups showed that the metal poor and old CSSs are sparsely distributed, intermediate metallicity and young CSSs are preferentially located along the East-West direction of Fornax centered in NGC 1399 and the most metal rich CSSs are concentrated in the vicinity of NGC 1399 and around the brightest galaxies. These different distributions for the metallicity and age subgroups allow us to constrain the mass assembly history of the Fornax Cluster. (4) Besides the Fornax cluster, we also discover five very diverse dwarf galaxies in another region of the sky, i.e. Hickson Compact Group 90 (HCG 90). Two of these dwarfs are a dwarf galaxy pair and one is a nucleated dwarf galaxy. According to their luminosity and structural parameters, they are similar to the dwarf galaxies we found in Fornax.

Authors:   , Vukasovic Herrero Tomás Vlado
Published: October 2023

La manufactura aditiva o impresión 3D ha ganado gran popularidad y su uso continúa creciendo en diversas áreas de la industria. Esto se debe a su principal característica de fabricar objetos con geometrías complejas, algunas son imposibles de crear mediante la manufactura tradicional. El proceso de fabricación por adición de capas sucesivas genera, propiedades mecánicas dependientes de los parámetros de impresión. La orientación dentro de la cámara de construcción es uno de los factores más relevantes. La respuesta mecánica de estas piezas aún no ha sido totalmente caracterizada. El objetivo de este estudio, que formó parte del proyecto FONDECYT INICIO N° 11170957, es caracterizar el comportamiento mecánico en el rango elástico de piezas de ABS y PLA fabricadas mediante impresión 3D en dos orientaciones ortogonales. Utilizando una impresora de escritorio de bajo costo se fabricaron probetas en dos orientaciones: horizontal y vertical. Luego, se realizaron ensayos de tracción, compresión y flexión para determinar la respuesta de las muestras impresas, se determinó el módulo de Young, el esfuerzo a la fluencia y el esfuerzo máximo. Se definió e implementó un modelo constitutivo que fue alimentado con los datos experimentales y que, finalmente se verificó con el ensayo de flexión de 4 puntos. La orientación vertical mostró peor desempeño mecánico en las pruebas de tracción. Sin embargo, en las pruebas de compresión no existe una diferencia importante causada por las orientaciones estudiadas. Se encontraron valores distintos de módulo de Young y resistencia máxima entre los ensayos de tracción y compresión para un mismo material y orientación. Un modelo bimodular lineal e isótropo representa de manera adecuada el comportamiento en el rango elástico de probetas sometidas a flexión de 4 puntos.

Authors: Khudaybergenova Zilola
Published: October 2023

The social formation of personality is a continuous natural process. Many social problems of a person and the ability to independently solve them are mainly determined by his social development. This article deals with such issues as the socialization of the individual, social education. Basic concepts and terms related to social education are interpreted. The content of social education is studied - a set of elements of social experience, which is transmitted to the younger generation in the process of social education, as well as a complex of socially significant qualities formed in young people. It describes the features of the subjects of social education - agents of positive socialization of the younger generation (and a particular child), creating conditions for the formation of a social subject. The approach of Anatoly Viktorovich Mudrik is mainly analyzed. The scientist took up this issue in the 70s. An approach to the definition of periods, mechanisms, factors of socialization, as well as the concept of "victims of socialization" is being explored. The novelty and modernity of the author's concept on this issue are put forward. The features and content of the concept of "subculture" are also considered.

Published: October 2023

The aim of the study is to investigate the effects of recreational rowing exercises on cancer patients, who have undergone prostate treatment, on their physical fitness and quality of life. A total of 37 participants (mean age of 59.10± 9.67 years) who completed their prostate cancer (PC) treatments and had no disability to exercise and participated in the recreational sea rowing program were included in the study. The study is consisting of two groups. The participants who refused to participate exercise (n=17 mean age 57.17±13.33 years) are Control Group (CG) and who accepted to join sea rowing program are Exercise Group (EG) (n=19 mean age 59.10 ±9.67 years). The program was carried out 3 days a week for 12 weeks, with an average of 60 minutes per day. Anthropometric measurements (height, weight, circumference measurements, BMI), VO2max and strength measurements were taken at the beginning and end of the program. Quality of life was assessed (EORTC-QLQ-C30 scale) and prostate cancer-specific module (EORTC QLQ-PR25) test. Since the data did not show normal distribution in the statistical analysis, centrality and prevalence criteria were determined for the continuous variables in the analysis, the Wilcoxon test was used for the differences between the pre-test and post-test measurements of the participants, and the Mann Whitney U test was used to determine the differences between the two groups. Statistically significant differences were found in physical fitness; arm thickness, one mile walking, peak force, 1000 m walking, strength and VO2max values (p<0.05). In the comparison of the two groups; Forearm thickness, upper leg circumference, lower leg circumference, average strength (kg), peak force (kg), average power (watt), Vo2max values were found significantly different (p<0.05).According to the result of EORTC-QLQ-C30; When the EG was compared with the pre-test, post-test and CG, a significant difference was found in the parameters of physical function, grip function, fatigue and constipation (p<0.05). According to EORTC QLQ-PR25 results, there was a significant difference in the urinary symptoms and sexual functioning sub-dimensions between the exercise and control groups (p<0.05).As a result of recreational sea rowing exercise, it was observed that the quality of life of the patients increased, the side effects of the disease decreased, aerobic capacity and strength characteristics improved.

Examining the power of the alcohol and tobacco industries in policymaking: Lessons and challenges for the Philippines and Singapore
Authors: Amul Gianna Gayle , Etter Jean-Francois
Published: October 2023

Abstract

Aims: Transnational alcohol and tobacco corporations are expanding operations in Southeast Asia. This study has two objectives: to examine the power of the tobacco and alcohol industries in shaping tobacco and alcohol policies in the Philippines and Singapore and to identify key lessons and challenges for alcohol and tobacco control.

Methods: We developed a conceptual framework from the literature on power and political, commercial and determinants of health. We collected data from official government documents, corporate documents, and news articles for content analysis on the tactics of the alcohol and tobacco industries. We also conducted 30 in-depth, anonymised interviews in the Philippines and Singapore and conducted a thematic analysis of the transcribed interviews.

Findings: Transnational and national alcohol and tobacco corporations use various tactics to influence the policy process for alcohol and tobacco control in the Philippines and Singapore. These industries utilised lobbying, litigation or threat of litigation, revolving doors, and marketing to exercise their instrumental power. These industries exercised their structural power by exploiting their market dominance, and public-private partnerships, promoting self-regulation, and benefiting from regulatory capture. They tapped framing tactics, corporate social responsibility activities and public-private partnerships to exert their discursive power.

Conclusions: The alcohol and tobacco industries’ exercise of instrumental, structural, and discursive powers is mutually reinforcing. Policymakers, researchers, and civil society organisations working on alcohol and tobacco control need to understand and tackle these powers in the context of power asymmetries within countries and consider the dynamics of local, national, and international laws and corporate practices.
Dual-Exceptionality among Students: A Review of the Crucial but Hidden Phenomenon
Authors: Khan Rafia , Khan Intakhab Alam
Published: October 2023

In the present scenario of an inclusive environment, the focus is mainly on providing equal education to all students despite special needs. In other words, inclusive education is the need of time. This study deals with the hidden phenomenon of a student who, on the one hand, has a kind of disability, on the other hand, possesses Giftedness. However, the masking effect of either disability or Giftedness keeps this phenomenon hidden from parents, teachers, and even students themselves. This hidden phenomenon, popularly known as dual-exceptionality, is not considered crucial in most schools, which becomes an obstacle to the academic and overall growth of those students who are not exactly like their peers. The present study helps to understand the concept of dual exceptionality and its impact on the learning process by providing an insight for researchers to draw conclusions regarding the presence of dual exceptionality, its impact on learners, and even on teaching. The findings lead to suggestions that such factors should be considered in pedagogy, and researchers, pedagogues, special educators and planners should take into account the factor of twice or dual exceptionality and ulitise for better educational outcomes. It is quite likely that the teachers need to be further trained so that they can handle inclusive classrooms effectively by employing differentiated instruction.
Top Edible Wild Plants of Eastern Mediterranean Region. Part III: Antidiabetic Activity
Authors: Azab Abdullatif
Published: October 2023

In the first two parts of this series of review articles, we presented the anticancer and anti-inflammatory activities of the most important wild edible plants of eastern Mediterranean region, which we named as the “Deca-plants” (D-P). In this review article, we will present the antidiabetic activities of these very important plants. Comparing with anticancer and anti-inflammatory activities, the overall antidiabetic activity of the D-P is moderate, but there are clear differences between the ten species. Based on this fact and on the knowledge that the D-P contain several natural products with proven antidiabetic activity, in the discussion section (4), possible future research directions will be indicated. In addition to presenting the reported antidiabetic activity of the plants, some important statistical facts about diabetes will be presented, as well as ethnomedicinal use of these plants for diabetes treatment, in the reviewed region. For the purpose of comparison and comprehensiveness, in the last part of this article, four Non-Deca-Plants with reported antidiabetic activity will be shortly reviewed, when the criteria of selection are wild and edible.

Published: October 2023

This study analyzed the physico-chemical characteristics of groundwater quality in some coastal areas of Akwa Ibom State, Nigeria. The study utilized primary data obtained from thirty boreholes in the area. The primary data consist of water quality parameters obtained from laboratory analysis of collected groundwater samples in the study area. Spatial distribution of groundwater constituents was carried out using ArcGIS 10.4 software. The result indicated that the groundwater in the coastal areas id acidic (pH ranges from 3.9 to 6.4); chloride ranges from 2.0mg/l to 52.0mg/l; total dissolved solids ranges from 4.8mg/l to 128.2mg/l; nitrate ranges from <0.01mg/l to 10.0mg/l; and turbidity ranges from 1.0 NTU to 3.11 NTU. The result also indicates that the groundwater is saline (salinity level range from 4.32mg/l to 85.8mg/l); turbidity at some locations also exceeds permissible standards. The study revealed that the quality of groundwater in the coastal areas is poor and not suitable for human consumption acidic and saline. Therefore, the groundwater in the coastal areas should be treated for acidity and salinity before domestic use.

Yolk sac tumors are uncommon and demonstrate rapidity in growth in young women. They are the second most common germ cell tumor following dysgerminomas. They are either pure or are associated with another form of germ cell tumor and can be highly polymorphic. Preservation of fertility is an important consideration in young patients.  Chemotherapy and surgery are mainstays of treatment if patients present early. Prognosis is poor for patients who present late.

Published: October 2023

The use of antibiotics in agriculture is believed to contribute to the spread of antibiotic resistance, and consumption of vegetables represents a route of direct human exposure to resistant bacteria found in soil. This study was carried out to isolate and characterize antibiotic resistant bacteria from poultry dropping fertilized farm soils in Aluu community Rivers State. Thirty-six (36) soil and waterleaf (Talinum triangulare) samples were collected for a period of three months from the vegetable farms and subjected to standard microbiological procedures such as standard plate counts, identification, sensitivity testing using Kirby-Bauer disk diffusion method and molecular identification. The total heterotrophic bacterial (THB), Staphylococcal, and total coliform counts ranged from2.72±0.52x106 to 7.30±3.54x106Cfu/g; 0x105to 4.30±0.28x105Cfu/g; 0x105 to 21.40±2.26x105Cfu/g and 2.65±0.21x105 to 3.10±0.85x105Cfu/g for FarmsA, B and C respectively. There was a significant difference (p˂0.05) in the total heterotrophic, coliform bacterial count but no significant difference in Staphylococcal and Salmonella-Shigella count between the different vegetable farms sampled in month one. THB, Staphylococcal, Faecal coliform (FC), coliform, Salmonella-Shigella counts ranged from3.80±1.83x106 to 4.69±1.69x106cfu/g; 1.08±0.04x105 to 1.40±0.11x105Cfu/g; 2.00±0.42x104 to 8.30±2.12x104Cfu/g; 3.95±0.21x105 to 5.95±0.21x105Cfu/g and 1.20±0.28x104to 2.40±0.85x104Cfu/g for FarmsA and B respectively. There was no significant difference (p˂0.05) in the THB, Salmonella-Shigella, Total coliform (TC) counts, but there was a significant difference in the Staphylococcal and faecal coliform counts between the different vegetable farms sampled for month two. The bacterial isolates identified were as follows; Escherichia coli, Enterobacter spp, Shigella spp, Salmonella spp, Pseudomonas spp Proteus spp, Staphylococcus aureus, Bacillus subtilis, Bacillus licheniformis, Serratia marcesens and Serratia nematodiphila. Forty-six (46) bacterial isolates were isolated from the soils and vegetables. Escherichia coli had the highest occurrence (75%) and Bacillus spp (9.09%) had the least occurrence. The susceptibility pattern of Bacillus spp, Staphylococcus spp, Enterobacter spp, Salmonella spp, Escherichia coli, Shigella spp, Pseudomonas sppand Proteus sppwere all susceptible to Ofloxacin, and gentamicin (100%) and resistant to Ceftazidime, Cefixime and Augmentin (100%). Hundred-percent (100%) of the bacterial isolates had multidrug resistance index greater than 0.2 and QnrA resistant gene were found in the resistant bacterial isolates. In conclusion, the use of antibiotic indiscriminately for agricultural purposes should be discouraged because of multiple antibiotic resistance.
Self Disclosure in the Interpersonal Communication Process of Establishing Friends with Benefits (FWB) Relationship Agreement on Telegram
Authors: Gabriela Monica
Published: October 2023

The phenomenon of Friends with Benefits (FWB) romantic relationships developed in Western countries that embrace freedom began to develop also in Indonesia with globalization and supported by technological developments. In contrast to dating relationships bound by feelings of love and commitment, the parties in a Friends with Benefits (FWB) relationship are only bound by an agreement on the benefits of sexual activity, without any feelings or c ommitments. The Telegram application has the advantage of large-scale community or group chat features. This research found a unique group community looking for Friends with Benefits (FWB) relationship partners in Indonesia. This research focuses on self -disclosure or self -disclosure in the process of interpersonal communication in personal chatting by prospective partners to establish a Friends with Benefits (FWB) relationship agreement on Telegram. This qualitative research approach with a case study method found four informants who are members of a particular community looking for Friends with Benefits (FWB) couples on Telegram and are establishing interpersonal communication to establish a Friends with Benefits (FWB) relationship agreement. The research findings show that the exploration of sexual desire accelerates the course of self -disclosure; women pursue the depth of personal profiles, men pursue the depth of intimacy, and self -disclosure measures a sense of security and comfort, which can determine the "deal".
Incorporation
Authors: Mattissen Johanna
Published: October 2023

Incorporation describes the morphophonological integration of the form of a lexical category into a full‐fledged verb form. It is a heterogeneous phenomenon that has to be described language‐specifically, through a range of parameters at all descriptional levels, in both form and function. The present entry illustrates these parameters with an in‐depth study of Nivkh, which features several theoretically relevant conditions on incorporation. In Nivkh, the incorporated forms, called ‘incorporees’, are syntactically and referentially active, and incorporation is the central means of undergoer argument encoding when primary object (including complement) and verb have the same information value.
High‐Throughput Design of Refractory High‐Entropy Alloys: Critical Assessment of Empirical Criteria and Proposal of Novel Guidelines for Prediction of Solid Solution Stability

Published: October 2023

Refractory high‐entropy alloys (RHEAs) are a new class of metallic alloys which have been extensively studied in the past decade due to their excellent high‐temperature performances. However, the design of new lightweight and ductile RHEAs is a challenging task, since an extensive exploration of the immense compositional space of multicomponent systems is practically impossible. Aiming to reduce the experimental effort, several research groups have proposed different predictive criteria to design new high‐performing HEAs. Nevertheless, the criteria proposed so far are often based on a limited amount of data and, generally, do not differentiate between refractory and nonrefractory HEAs. To overcome these limitations, herein, a comprehensive database of properties of 265 RHEAs reported in the open literature from 2010 to 2022 is developed. Such a database is used to assess the validity of predictive empirical criteria and new guidelines for the prediction of solid solution stability in RHEAs are proposed.

The manipulation of magnetization through optically generated ultrafast spin currents is a fascinating area that needs a thorough understanding for its potential future applications. In this work, a comprehensive investigation of helicity‐driven optical spin‐orbit torque in heavy metal/ferromagnetic metal heterostructures is presented, specifically cobalt capped with gold or platinum, subject to laser pumping at different wavelengths. The results demonstrate up to tenfold enhancement in optical spin‐orbit torque quantum efficiency for gold compared to platinum of the same thickness when pumped with a visible laser. Additionally, the study provides the first experimental analysis of the photon energy dependence of optical spin‐orbit torque and derives the optical spin orientation spectra for both gold/cobalt and platinum/cobalt heterostructures. A key insight gained from the study is the impact of photon energy‐dependent spin transport in the system, which suggests the use of a high photon energy pump for efficient spin transport. These findings highlight the potential of spin current generation and manipulation in gold/ferromagnet heterostructures for a wide range of applications such as all‐optical magnetization switching, spin‐wave generation and control, and spintronic terahertz emission.

The development of solid‐state sodium‐ion batteries (SSSBs) heavily hinges on the development of an superionic Na+ conductor (SSC) that features high conductivity, (electro)chemical stability, and deformability. The construction of heterogeneous structures offers a promising approach to comprehensively enhancing these properties in a way that differs from traditional structural optimization. Here, this work exploits the structural variance between high‐ and low‐coordination halide frameworks to develop a new class of halide heterogeneous structure electrolytes (HSEs). The halide HSEs incorporating a UCl3‐type high‐coordination framework and amorphous low‐coordination phase achieves the highest Na+ conductivity (2.7 mS cm−1 at room temperature, RT) among halide SSCs so far. By discerning the individual contribution of the crystalline bulk, amorphous region, and interface, this work unravels the synergistic ion conduction within halide HSEs and provides a comprehensive explanation of the amorphization effect. More importantly, the excellent deformability, high‐voltage stability, and expandability of HSEs enable effective SSSB integration. Using a cold‐pressed cathode electrode composite of uncoated Na0.85Mn0.5Ni0.4Fe0.1O2 and HSEs, the SSSBs present stable cycle performance with a capacity retention of 91.0% after 100 cycles at 0.2 C.
Circularly Polarized Scattering Radiation From a Silicon Nanosphere

Published: October 2023

A dielectric nanosphere with orthogonal electric dipole (ED) and magnetic dipole (MD) Mie resonances can be a nanoantenna radiating circularly polarized light in specific directions if the amplitudes and the phase relations are properly designed. First, theoretical calculations show that a silicon nanosphere illuminated with a linearly polarized plane wave radiates circularly polarized light at the wavelength in between the ED and MD resonances if the refractive index of a surrounding medium (nm) is ≈1.3; the ellipticity of the scattered light can be >0.99 when nm is in a 1.19–1.35 range. Size‐purified silicon nanospheres suspended in water (nm = 1.33) are then prepared, and the angle‐ and circular‐polarization‐resolved scattering spectra are studied. It is experimentally demonstrated that circularly polarized light is radiated in specific directions under linearly polarized plane wave illumination. The results also show that the wavelength of the radiation of circularly polarized light can be controlled in the whole visible range by controlling the silicon nanosphere diameter in 100–200 nm range.

In recent years, the development of carbon dot‐based fluorescent nanoparticles for bioimaging applications has attracted the attention of the scientific community. However, many of these systems absorb and emit in the blue–green region of the electromagnetic spectrum, limiting their application in bioimaging. Herein, the facile design and development of highly efficient two‐photon excitable red‐emissive carbon dots are reported and their high performance in bioimaging applications is demonstrated. The importance of aromatic precursors in developing red‐emissive carbon dots is demonstrated. The optimized carbon dots are highly biocompatible and nontoxic, with remarkable photostability in cells under two‐photon near‐infrared excitation. The present study points to the great potential of two‐photon excitable red‐emissive carbon dot as an efficient bioimaging agent for cellular biolabeling, long‐term and real‐time cellular imaging, and high‐resolution deep‐tissue imaging in complex biological systems.

Although various ferroptosis inducers including magnetic nanoparticles (Fe3O4) and iron‐organic frameworks have been applied in cancer treatment, the mild immunogenicity, low targeting efficiency to the tumor, and poor tissue penetration have limited the therapeutic efficacy. Herein, a supramolecularly engineered conjugate between living bacteria (facultative anaerobic Salmonella typhimurium VNP20009, VNP) and cancer cell membranes‐coated Fe3O4 nanoparticles is developed for improving targeted delivery of Fe3O4 nanoparticles into the tumor tissue and for synergistic ferroptosis and immunotherapy of tumor. The enhanced ferroptosis induced by both Fe3O4 nanoparticles and the loaded ferroptosis inducing agent (sulfasalazine (SAS)) effectively inhibits tumor growth and generates immune response via immunogenic cell death (ICD). The colonization of VNP in tumors also induces adaptive immune responses and further promotes ferroptosis. Fundamentally, the supramolecular conjugate of VNP and cell membranes‐coated Fe3O4 can potentiate the therapeutic capability of each other through mutually magnifying the ferroptosis and immunotherapy, resulting in significantly enhanced antitumor effects.
Boosting Oxygen Reduction through Microenvironment Modulation to Enhance Mass Transportation

Published: October 2023

Electroreduction of oxygen driven by renewable electricity holds significant promise for the sustainable production of value‐added hydrogen peroxide (H2O2). While water is a desirable source of protons and electrons for this reaction, its low gas solubility often limits the transportation of gas molecules and consequently leads to large concentration overpotential, resulting in unsatisfactory energy efficiencies. Herein, a facile and effective strategy to promote the 2e− oxygen reduction reaction (ORR) through microenvironment modulation is presented. In this work, it is specifically aimed to facilitate oxygen transportation at the reaction interface, particularly at high rates. To achieve this, hydrophobic polytetrafluoroethylene (PTFE) particles are introduced into a catalyst layer containing amino‐group‐functionalized carbon nanotube (CNT‐NH2) as the ORR catalyst for H2O2 production. As a result, the PTFE‐modified CNT‐NH2‐based gas‐diffusion electrode (GDE) substantially improves ORR activity. At 100 mA cm−2, the PTFE‐modified CNT‐NH2 achieves a high cathodic energy efficiency of 92%, 1.5 times higher than the pristine CNT‐NH2‐based GDE (63%). Detailed kinetic analysis reveals that this enhanced ORR performance is indeed due to the enhanced oxygen transportation induced by the persistent hydrophobic microenvironment created by the PTFE‐modified catalyst layer, reducing the concentration overpotential during ORR.
