Este estudio se realizó con el objetivo de evaluar el efecto del anticuerpo de yema de huevo de gallina inmunoglobulina Y (IgY) y el núcleo proteico NuPro® en la dieta de corderos en crecimiento, sobre su comportamiento productivo, tiempo de consumo y características de la canal. Se utilizaron ocho corderos machos enteros en crecimiento de la raza Pelibuey. Las dietas se prepararon con una ración base de sorgo y pasta de soya, más los tratamientos: sin IgY y sin NuPro (SA/SN); con 0.125% de anticuerpos (CA/SN); 4.0% de NuPro (SA/CN) y 0.125% de anticuerpos, y 4.0% de NuPro (CA/CN). Se evaluó el consumo diario de alimento (CDA), la ganancia diaria de peso (GDP) y la conversión alimenticia (CA) de 0-28 d, 29-56 d y 0-60 d, así como el tiempo de consumo y de rumia, durante 24 h y características de la canal. Se utilizó un diseño completamente al azar, con arreglo factorial 2x2. El CDA, la GDP y la CA no mostraron diferencia (p≤0.05) en la etapa de 0-56 y 29-56 d, pero fueron mayores (p≤0.01) en los tratamientos SA/SN y CA/SN. El CDA, la GDP y la CA para el tiempo de consumo incrementó (p≤0.05) en animales que consumieron anticuerpo y/o NuPro solos o ambos, sin afectar (p≥0.05) el tiempo de rumia y masticación. El peso y el rendimiento de la canal caliente y frío fueron iguales (p≤0.05). El CDA fue mayor en el testigo (SA/SN) y en los corderos que tuvieron dieta con anticuerpos (CA/SN), reflejándose en la GDP, sin afectar la CA durante los primeros 28 d, no hubo efecto en las mismas variables de los 29-56 y 0-56 d. El tiempo de consumo aumentó en corderos que consumieron las dietas con IgY y NuPro.

Published: January 2024

La rizoctoniasis o costra negra es una enfermedad de la papa, producida por el hongo Rhizoctonia solani, el cual afecta la emergencia y el desarrollo de la planta, provoca la producción de una gran cantidad de tubérculos deformes, protuberantes, partidos y con costra negra, y finalmente, reduce el rendimiento del cultivo. Para el control de esta enfermedad, se usa Pencycuron, un fungicida no sistémico con acción protectora, sin embargo, para un control eficiente es necesario evaluar la susceptibilidad de los grupos de anastomosis (GA) de R. solani a este fungicida, por lo que el objetivo de este estudio fue evaluar el nivel de susceptibilidad al Pencycuron de los GA de R. solani encontrados en ocho regiones productoras de papa en México. Se colectaron plantas de papa con síntomas de costra negra, de las que se aislaron 21 cepas de R. solani en medio de cultivo PDA. Se identificó a los GA: AG-3 y AG-4 (AG, por sus siglas en inglés) en una proporción de 52.4 y 47.6 % respectivamente, mediante la confrontación de hifas. En las muestras colectadas en Navidad, N. L., Arteaga, Coah., Ayahualulco, Ver., Tapalpa, Jal. y Huatabampo, Son., se encontró el AG-3; y en las colectadas en Aldama, Chih., Mochis, Sin., Guasave, Sin. y en Arteaga, Coah. se encontró el AG-4. Los resultados indicaron que las cepas de R. solani fueron inhibidas a una CI50 de 0.014 a 39209.5 mg i.a./L, detectando un factor de resistencia (FR) muy elevado. El FR máximo para aislados del AG-3 fue de 145 y de 3920956 para los aislados pertenecientes al AG-4.

Published: January 2024

El gorgojo del maíz (Sitophilus zeamais Motschulsky), es considerado la plaga del maíz en almacén más importante en México y llega a ocasionar pérdidas de hasta de 30 y 40 % de la producción durante el almacenamiento. El uso de productos clorados y fosforados para su control puede ocasionar daños a la salud humana, animal y ambiental, por lo que se requiere de tratamientos alternativos. El objetivo de este estudio fue determinar el efecto insecticida de los extractos de hojas de lila (Melia azedarach L.) sobre el gorgojo del maíz S. zeamais y su respuesta a través del tiempo en la calidad fisiológica de semillas de maíz almacenado. Se utilizó semilla de maíz AN-447 almacenada durante 80 d. Los extractos de hojas de M. azedarach se aplicaron a la semilla de maíz almacenado a 100, 75, 50 y 25 %. Para evaluar el efecto de los extractos sobre la calidad fisiológica de la semilla se realizaron muestreos cada 40 d y se determinó la capacidad de germinación y el vigor (longitud media de plúmula y radícula). El efecto insecticida de los extractos fue muy bajo, menor al 16 % de mortalidad durante las primeras 24 h después de la infestación. Sin embargo, a los 7 d de almacenamiento, los extractos provocaron una mortalidad del 90 % de S. zeamais con el 100 % de la concentración del extracto de hoja tierna en metanol al 99.80 %. Los extractos de hojas de M. azedarach no dañaron la calidad fisiológica y el vigor de la semilla durante los 80 d de almacenamiento.

Published: January 2024

La calidad de la canal en la producción de carne de res está determinada por las condiciones de manejo y las características del animal vivo. El objetivo de este estudio fue evaluar el efecto de las características del animal vivo sobre algunas características de la canal de novillos jóvenes de las cruzas Bos taurus x Bos taurus y Bos taurus x Bos indicus. Se relacionaron las características: peso al sacrificio, altura a la cadera, ganancias diarias de peso y grupo racial de los animales vivos con las variables: grados de calidad y grados de rendimiento (grasa subcutánea, grasa en riñón pelvis y corazón, peso de la canal caliente, músculo longissimus dorsi). Se utilizó información colectada de 1991 a 2009 de novillos jóvenes y sus canales. Se utilizó un diseño completamente al azar con arreglo factorial, en donde el año se combinó de manera independiente con las características del animal vivo. Se encontró un aumento(p=0.05) en las variables de calidad y rendimiento del canal causado por un aumento en el peso al sacrificio, ganancia diaria de peso y la altura a la cadera, pero el área del músculo longissimus dorsi por cada 100 kg de peso de la canal caliente. Todas las variables de calidad de la canal fueron mayores para los novillos de la cruza de Bos taurus x Bos taurus que los de Bos taurus x Bos indicus. No se encontró diferencia (p>0.05) para el grado de rendimiento en los novillos de las diferentes cruzas. Se concluye que novillos sacrificados con mayor peso, mayor altura a la cadera, que ganaron más peso durante la engorda y de cruzas Bos taurus x Bos taurus producen las canales de mayor calidad y menor rendimiento en cortes.

Los extractos y concentrados del gel de hoja de sábila [Aloe barbadensis Mill. (sin. Aloe vero L.)], son ampliamente demandados para la elaboración de cosméticos, bebidas saludables y productos de cuidado personal. El principal problema de las empresas transformadoras de estos productos es el desconocimiento del mercado consumidor. Debido a lo anterior, se realizó este estudio con el objetivo de determinar el perfil del consumidor de productos de sábila en la ciudad de Monterrey, N.L. en el norte de México. En el estudio de campo se aplicaron 80 encuestas a consumidores de productos de sábila. La selección de los elementos de la muestra se realizó mediante un estudio exploratorio; la selección de los consumidores se hizo en forma aleatoria; y las encuestas se aplicaron a hombres y mujeres mayores de 18 años. Se utilizaron pruebas de t-Student y Ji cuadrada para las variables cuantitativas y cualitativas respectivamente. Se construyó una matriz de correlaciones, considerando todas las variables, posteriormente se diseñaron y aplicaron dos modelos de regresión multivariado para hacer predicciones que confirmaran la relación causa-efecto entre la cantidad de productos de sábila adquiridos por los consumidores y el gasto efectuado por los compradores, así como las características relevantes del perfil. Con lo anterior, se determinó que los consumidores de productos de sábila son mujeres adultas, madres de familia, dedicadas únicamente a las labores del hogar. Se caracterizan por ser leales a la marca preferida, entre más productos de sábila conocen, más productos adquieren, y se enteraron de estos productos a través de anuncios en televisión.

Статья раскрывает основные результаты исследования в рамках Проекта грантового финансирования AP14871693 «Организационно-методологические основы обеспечения инклюзивности профессионального ориентирования обучающихся школ» (2022-2024 гг.).  Проект направлен на исследование проблемы, заключающейся в неразработанности механизмов, координирующих действия всех стейкхолдеров в подготовке обучающихся к осознанному выбору профессии, отвечающей индивидуальным возможностям и особым потребностям обучающихся. Согласно плану реализации проекта проведено исследование состояния профессиональной ориентации и социализации обучающихся школ в условиях инклюзивного обучения. Авторы обращают внимание на ежегодный рост количества детей с особыми образовательными потребностями и быструю переменчивость запросов рынка труда, что вызывает проблему в их профессиональном самоопределении в современных условиях и приобретает особую актуальность. В ходе исследования реализованы такие задачи, как изучение особенностей системы организации профориентационной работы в современной школе, роли и вовлеченности стейкхолдеров в систему профессионального ориентирования, выяснение мнения педагогов о готовности обучающихся к осознанному выбору профессии, выявление факторов, препятствующих эффективности профориентационной работы в школе. По результатам исследования сформулированы выводы о разрозненности и непоследовательности в действиях стейкхолдеров, что приводит к системным перекосам рынка труда, росту сегмента низкоквалифицированной рабочей силы и безработных, в числе которых представители уязвимой части молодежи. В качестве решения выявленных проблем предлагается теоретически обоснованная системная инновационная Модель профессионального ориентирования обучающихся школ с учетом их индивидуальных возможностей и особых потребностей. Целесообразность и эффективность данной Модели обоснована соблюдением принципов системности, доступности, инклюзивности, открытости, согласованности, непрерывности и включением таких важных аспектов, как организационный, экономический, правовой, образовательный, нравственный.

Реалии современной информационной эпохи показывают, что содержание школьного образования, в том числе научного и естественно-математического образования, нуждается в значительном пересмотре. Обязательному обучению основам программирования в общеобразовательной школе, включая начальное образование, также способствовал такой фактор, как появление многочисленных доступных и простых инструментов для обучения программированию в разном возрасте.  Программирование считается наиболее эффективным инструментом, с помощью которого обучение становится более интересным, быстрым, точным и простым, а знания и навыки, полученные в процессе обучения, являются научными, глубокими и обобщенными. В ходе исследования были проанализированы 42 источников по программированию в школе на казахском, русском и английском языках. Теоретико-методологический анализ научных исследований по данной тематике позволяет выделить следующих подходов обучения программированию в школе: традиционные технологии обучения, ориентированные на изучение языков программирования; обучение с использованием образовательной робототехники; обучение на основе геймификации; обучение с использованием элементов блокчейна, виртуальной реальности и искусственного интеллекта. Результаты данного исследования могут быть методологическими предпосылками при определении целей и задач школьного курса программирования с учетом достижения современной науки и технологии.
Theoretical Possibility of Quantum Stabilization of Traversable Wormholes
Authors: Denis Olivier
Published: January 2024

In this article, we argue that we can explain quantum stabilization of Morris-Thorne traversable wormholes through quantum mechanics. We suggest that the utilization of dark matter and dark energy, conceptualized as negative mass and negative energy tied to the universe's information content, can stabilize these wormholes. This approach diverges from the original Morris-Thorne model by incorporating quantum effects, offering a credible and adequate source of the exotic matter needed to prevent wormhole collapse. We reassess the wormholes' stability and information content considering the new calculated revised vacuum energy based on the mass of bit of information. This new calculation makes the wormholes more viable within our universe's limits. Furthermore, we explore the connection between dark energy and the vacuum energy of space, highlighting the broader cosmological significance of traversable wormholes, particularly in relation to the universe's expansion. The quantum stabilization of Morris-Thorne traversable wormholes marks a pivotal advancement in the field of physics.
Validation of reanalysis for Central Europe PERUN/Reanalysis
Authors:   Ústav fyziky atmosféry AV ČR, v. v. i., Beranová Romana , Rulfová Zuzana , Sokol Zbyněk
Published: January 2024

PERUN/Reanalysis is based on the ALADIN numerical forecast model, which has been adapted for climatological calculations. To serve as one of the reference sets for estimating expected climate changes in the coming decades, it needs to undergo validation against station measurements and possibly against other commonly used data sets. In this conference paper, we will examine the validation of basic meteorological quantities across the computational domain of the ALADIN model. To achieve this, we will use station data from the ECA&D database, station data in the regular network (Eobs), and the ERA5 global reanalysis. Validation will be conducted for the period from 1990 to 2014. During validation, our primary focus will be on air temperature (minimum, maximum, and mean) and precipitation. We will also examine additional variables, including wind speed.
Evaluation of precipitation totals simulated by the ALADIN/PERUN atmospheric reanalysis at high spatial resolution
Authors:   Ústav fyziky atmosféry AV ČR, v. v. i., Bližňák Vojtěch , Zacharov Petr
Published: January 2024

Atmospheric reanalyses represent powerful tools for obtaining information about the state of the atmosphere in history, which is obtained by numerical weather prediction (NWP) models whose predictions may (but may not) be improved through the assimilation of measured data. Significant developments in computer technology have recently enabled to increase their spatial resolution so that even meteorological phenomena of a local nature can be better captured. However, most NWP models compensate this capability by reducing the computational domain, which largely limits the use of these forecasts for the following meteorological, climatological and/or hydrological applications. The newly developed ALADIN/PERUN atmospheric reanalysis provides simulations of various meteorological variables at high spatial (2.3 km) and temporal (1 h) resolution over most of Europe between 1989 and 2020. Due to the high resolution of the reanalysed data, it can be expected that precipitation fields will capture local-scale processes well, and thus reproduce more faithfully, for example, heavy convective precipitation. The presented paper aims to evaluate this capability based on gauge-adjusted radar estimates of precipitation totals during warm parts of the year when strong convective but also stratiform precipitation occurs in Central Europe. The accuracy of the localization and precipitation sums will be evaluated for two different runs of the NWP model. The first one (ALADIN/Reanalysis) involves a complete assimilation of the observed data every 6 hours using a 4D-VAR assimilation scheme. The second (ALADIN/Evaluation Run) uses only the boundary conditions from the ERA-5 global reanalysis and the calculation of the forecasts is not further modified based on measured data. Comparing the two runs will provide us with information about the level of physical description in the NWP model as well as the effect of assimilation on the resulting precipitation fields. In addition, the paper is unique in that it will use detailed fields of "observed" precipitation totals at high spatial resolution, which conventional rain gauge data cannot offer.
Bias correction of regional climate model outputs: statistical transformations of precipitation series from the climate model ALADIN in the project PERUN
Authors:   Ústav fyziky atmosféry AV ČR, v. v. i., Martínková Marta
Published: January 2024

The outputs of regional climate models are biased. Regarding the bias correction of outputs from a climate model, the two fundamental approaches exist. First approach (e.g., Delta change method) gets the information on climate signal from comparison of the model control and future periods. Such information (change factor) is then applied to modify the observational data. Bias correction method gets the information on model bias from comparison of observational data and model outputs for the control period. The model outputs for future period are than corrected using this information on the model bias. This contribution is focused on the possibilities for bias correction of the model ALADIN (CNRM-ESM2-1) in the project PERUN and the precipitation series in daily time step for SSP5-8.5 scenario. Different statistical transformations are compared: methods based on statistical distribution, parametric transformations and non-parametric transformations (empirical quantiles method).
Scenarios of Future Subdaily Rainfall Intensities in Slovakia
Authors:   Slovenský hydrometeorologický ústav, Onderka Milan ,   Ústav vied o Zemi SAV
Published: January 2024

Time series of 3-hour precipitation totals for the RCP8.5 scenario obtained from regional climate models EURO-CORDEX were processed to derive estimates of future rainfall frequencies. From the annual maxima of 3-hr precipitation totals, quantile values were estimated using a non-stationary GEV distribution with Bayesian inference. Using the envelope curves of short-term rainfall intensities, we estimated possible sub-hourly design intensities for the time horizons of 2040 and 2080 with a spatial resolution. The raster maps were subsequently re-gridded into 500 x 500 meter resolution using non-linear triangulation.

The paper demonstrates “collaboration” between the stochastic weather generator SPAGETTA (WG) and Regional Climate Models (RCM) in analysing impacts of Climate Change (CC). In the first part of the paper, the generator is compared with the ensemble of 19 RCMs in terms of their ability to reproduce 11 spatial temperature and precipitation indices in eight European regions; the indices are based on registering days and spell exhibiting spatially significant occurrence of dry, wet, hot or cold weather, or possible combination of dry-or-wet and hot-or-dry conditions. The obtained results indicate that both methodologies provide weather series of comparable quality. In the second part of the paper (which was done only for the Central Europe region), the WG parameters are modified using the RCM-based CC scenarios and the synthetic weather series representing the future climate are produced. This experiment is based on a set of CC scenarios, which consist of changes in selected combinations of following characteristics: (1) mean temperature, (2) temperature variability, (3) daily average precipitation (considering only wet days), (4) probability of wet day occurrence, (5) spatial lag-0 and lag-1day correlations of temperature and precipitation series. The synthetic series generated for each version of the CC scenario are analysed in terms the above mentioned spatial validation indices, the stress was put on effect of each of the five component of the CC scenario on individual validation indices. The results of the experiment indicate that the changes in temperature means is the main contributor to the changes in the validation obviously, except for the purely precipitation-based indices. Positive changes in the lag-0 and lag-1day correlations of both temperature and precipitation are the second most significant contribution to the changes in the validation indices.

The European Environment Agency (EEA) report "Europe's changing climate hazards – an index-based interactive EEA report" defines 16 climate change risks for Europe, which are assigned to the 6 types of risk identified by the Intergovernmental Panel on Climate Change (IPCC) in the Sixth Assessment Report. Of the above-mentioned areas, the relevant risks for the territory of the Czech Republic are associated with the occurrence of extreme air temperature and changes in average air temperature, changes in precipitation regime and occurrence of extreme precipitation, occurrence of drought, occurrence of weather suitable for fires, changes in air flow and occurrence of extreme wind, changes in snow cover. In my contribution, I focus on assessment of changes in the occurrence of extremely high air temperature and extreme wind in the Czech Republic between 1961–1990 and 1991–2020. The changes in the frequency of occurrence of these phenomena have been evaluated and the trend and intensity studied.

Published: January 2024

Data from interpolated daily rainfall totals for the period 1961–2020 were used for the area analysis of 1-day annual rainfall maxima. The analysis was performed in a regular grid of square areas ranging from 16 to 324 km². For each area and individual year, maximum areal 1-day rainfall totals were derived for the period between 15 April and 15 October. Datasets of 60 seasonal maximum values were created and further statistically processed. The results were analysed in the GIS environment. As expected, there are noticeable differences between lowlands, uplands and mountain areas in general. In addition, regional differences are visible, e.g. greater variability of 1-day rainfall maxima in Bohemia compared to Moravia. Furthermore, the dependence of statistical characteristics of 1-day rainfall maxima on the considered size of the area was investigated.

Droughts and floods are extreme hydrological events with increasing impacts due to climate change. The PERUN project focuses on drought assessment in the Czech Republic and the innovation of the warning system by ČHMÚ. The Water Act amendment introduces the obligation to inform about drought and forecasting services. Tools are being developed for predicting the state of water resources and creating plans to address drought and water scarcity. The competent body is the Drought Commission at the regional or national level. Warning information is available on the HAMR portal along with the local threshold limits (MSL) of water sources.

The release of a greater amount of natural organic matter (NOM) within climate change is registered in many catchments with peatbog areas. The aim of our research is to study the dynamics of releasing dissolved organic carbon (DOC) into surface water in headwater areas with peatbogs. DOC concentrations are analysed in relation to extreme rainfall-runoff (R-R) events and according to the hydrological preconditions of the basin. These preconditions are described using selected hydroclimatic variables (14 days before the R-R event). The source data comes from stations of the Faculty of Science, Charles University, and the Czech Hydrometeorological Institute. For the evaluation of relations and processes, the Principal component analysis (PCA), hysteresis loops or Pearson correlation coefficient was used. The lag time of DOCmax for Qmax, the dependence of DOCmax and groundwater levels were studied. The influence of flow rate on the decline and ascent phases of DOC concentrations by hysteresis loops and the influence of the number of partial flow maximums on the amount of transported DOC during the R-R event was analysed. Our first results show that great influence on the dynamic of DOC concentration in surface water has the change in groundwater-levels in the peatbog and the outflow amount during the R-R event. The hydroclimatic preconditions of the basin have also a significant influence on the DOC release. Changes in concentrations during R-R events also occurred for other compounds that were studied additionally. Particularly significant was the increase in metals (mainly Fe, Al, Mn) and base cation (K) and decrease in nitrate nitrogen.

Climate change is causing a higher frequency of hydrological extremes that affect surface water quality. On changes in water quality due to hydrological drought we are focused in this article. Flows below Q355, which define hydrological drought, were found to be more frequent in most streams in the last two decades than in previous decades. Statistical analysis of changes in water quality is carried out in selected profiles of the river network, in which surface water quality is monitored, and where near the gauging profile is situated. The first preliminary results show that the hydrological conditions impact significantly on abundance of many pollutants, the methods need further improvements and verification. At the same time, in 2023, we selected the localities in which field research is managed to find out attenuation of nutrients and organic pollution in longitudinal profile of the river in a grid of approximately 1 to 2 km downsteam. The first results show that Rakovnický stream under Rakovník, rivers Metuje under Náchodem and Bílovka pod Bílovec are suitable for this research. Interim results from sampling during the hydrological drought in summer confirmed a significant decrease in total nitrogen, ammonia nitrogen and organic pollution. Conversely, the loss of phosphorus after first mixing waste and surface water was downstream minimal.

Published: January 2024

The Ulu-Apad leadership system in Pekraman village, which can be classified as a leadership system in the Bali Aga village, can be interpreted that Ulu is the head or leader, while Apad is the support, or buffer, so if it is interpreted that the Ulu - Apad system is a hand-in-hand leadership system. , which starts from the main to the end, means that this leadership system has a form and function that is very different from the pekraman village leadership system in general in Bali. The relationship between the Ulu-apad system and the Bali Provincial Regulation No. 4 of 2019 was based on the conditions at that time which urged the government in general to take action in public conditions which at that time were still experiencing uncontrolled conditions. This ulu apad system had a tremendous influence on society in 2019. Research Method uses qualitative descriptive research methods, qualitative descriptive research which is intended as a measurement of certain social phenomena that is able to develop concepts and collect facts but does not carry out hypotheses.

 

Abstrak

Sistem kepemimpinan Ulu-Apad desa pekraman yang dapat digolongkan merupakan sistem kepemimpinan di desa Bali aga, dapat diartikan bahwa Ulu merupakan kepala atau pemimpin, sedangkan Apad merupakan penopang, atau penyangga, jadi jika diartikan bahwa sistem Ulu – Apad merupakan sistem kepemimpinan saling bahu-membahu, yang mulai dari utama sampai akhir, maksudnya adalah sistem kepeimimpinan ini mempunyai bentuk, fungsi yang sangat berbeda dengan sistem kepemimpinan desa pekraman pada umumnya yang ada di Bali. Keterkaiatan sistem Ulu-apad ini dengan Perda Provinsi Bali No.4 tahun 2019 adalah  berdasarkan atas kondisi pada saat itu yang mendesak pemerintah secara umum untuk mengambil tindakan dalam kondisi publik yang pada saat itu masih mengalami kondisi yang tidak terkontrol. Sistem ulu apad ini memberikan pengaruh yang luar biasa terhadap masyarakat pada tahun 2019.Metode Penelitian menggunakan metode penelitian deskritif kualitatif, penelitian deskriptif kualitatif yang dimaksudkan sebagai pengukuran fenomena sosial tertentu yang mampu mengembangkan konsep serta menghimpun fakta tetapi tidak melakukan hipotesis.

The Impact of Corporate Governance Structure on the Financial Risk
Authors:   South China Business College Guangdong University of Foreign Studies, China, Xu Tao
Published: January 2024

This paper first introduces the research background of financial risks and corporate governance structure, using a sample of A-share companies listed in Shanghai and Shenzhen Stock Exchange from 2016 to 2018. It applies Z-score to measure financial risks and finds some quantitative methods to measure the factors in the corporate governance structure. This paper uses multiple linear regression model to analyze the correlation between financial risks and the corporate governance structure. The results show that ownership concentration, executive shareholding percentage and executive compensation have the most significant influence on financial risks and all of them are negatively correlated with financial risks. Therefore, we recommend companies to improve the non-executive director mechanism of listed companies, to maintain a relatively concentrated ownership structure, and to take effective incentive mechanism for executives. These recommendations can help companies better manage financial risks.

Authors:   School of Journalism, College of International Communication of South and Southeast Asia, Yun Nan University, China, She Jia
Published: January 2024

As a living environment for residents, the community is an important carrier and platform for health communication that cannot be ignored. From a constructivist perspective, the meaning of health can only be expressed through "insiders" in cultural contexts. The participation of individuals, as the target of health mobilization, should not be overlooked, and this bottom-up power is crucial in determining the effectiveness of health mobilization. This article explores the connection between the material and representational dimensions of health communication in community public spaces through the use of identifiers, symbols, and media. It seeks to understand the meaning of health from a collectivist and community level, emphasizing the central role of structural factors and culture in the process of community health communication. The agency of community residents is also highlighted, and the localization context facilitates the stimulation of shared emotions and collective action, thus forming an "internal expression" of health communication within the community.

The current study is aimed at examining authenticity and inspiration within the context of consumer behavior. For this purpose, the researcher investigated the impact of brand authenticity on brand outcomes (brand advocacy and brand love). The objective is to provide a comprehensive understanding of the entire decision-making process through mediating mechanisms and customer inspiration based on the proposed linkages. A non-probability convenience sampling technique has been used for this study. The study first adopted the nominal group technique to establish the existence and understanding of the constructs in our context, followed by a cross-sectional research design to investigate how witnessing an authentic experience influences the consumption behavior of the consumers. Finally, the researcher collected the data through a questionnaire adopted and validated from past research. The deductive approach, survey strategy, and quantitative methodology are used for the current study. Employing a cross-sectional research design, the data has been collected through multi-stage and convenience sampling (N = 261). Analysis such as measurement model, structural model, mediation analysis, and moderation analysis were performed via means of structural equation modeling through Smart PLS4. Findings indicate that a) results reveal significant relationships for all direct path hypotheses, and b) customer inspiration found a significant mediator between brand authenticity and brand outcomes (brand advocacy and brand love).
