Natural materials had various types of primary and secondary metabolite compounds that were useful for treating a disease. Plant materials that contain high levels of secondary metabolites could be developed into raw materials for traditional medicines. An example of the development of natural medicine which was in high demand is making traditional medicinal raw materials which have antibacterial properties. These could add to the type of therapy for a disease with smaller side effects. The aim of this study was to determine the activity of the purified extract gel preparation of rosella petals as an antibacterial. The extract was obtained from the maceration method which was then followed by purification. The antibacterial activity test in this study used the well diffusion method. Detection of metabolites by Thin Layer Chromatography (TLC) includes the stationary phase of silica GF254 and the mobile phase Toluene: Acetic acid: Formic acid (6:6:1). The concentration of purified extract of rosella petals for the formulation was 5, 15 and 25%. Data analysis was carried out with the One Way Anova test with a 95% confidence level. The results of the research that the purified extract gel preparation of rosella petals has the potential to inhibit the growth of Escherichia coli bacteria in the sensitive category at a concentration of 25%. The results of a positive phytochemical screening for flavonoid compounds were indicated by the formation of a red-orange color in the test and identification using TLC produced an Rf of 0.85 which has similarities with previous studies. The conclusion of this study was that the ETKR gel preparation with a concentration of 25% was sensitive as an antibacterial

Published: June 2023

The purpose of this study was to assess the impact of social media marketing on South African consumers' brand selection in Durban, with the primary goal of determining the extent to which social media marketing influences consumers' decision-making when selecting a brand. This research used a quantitative research method and non-probability sampling approaches. Only 400 questionnaires out of 450 were collected. In this study, descriptive, and inferential statistics were used. The results of this study suggest that social media is an extremely effective communication tool that might be used to sway consumers' judgments when selecting where to buy. All users claimed to utilize computer-generated platforms, with Facebook being the most widely used. Customers claimed that the more information they learnt about a business through social media, the more they desired to purchase it, and the opposite was also true. According to the report, businesses should publish promotional events, competitions, and giveaways on their social media brand pages to increase customer interest and traffic. Another recommendation was for marketers to establish a personality who can effectively represent a brand on social media and give it a lively mood that will attract customers.

Published: June 2023

Street running by amateurs athletes became a popular sports practice amongst adults around the world, who seeks healthy habit and a life quality. Prior evidence showed that the adoption of good practices is related to the development of an enhanced sustainable mindset. So far, few studies have examined the association between the healthy lifestyle of amateur runners and environmental values. The aim of this study was to examine the relationship between sports practice and environmental values. This investigation used survey data collected with amateur runners to examine the antecedents and consequences of healthy habits on sustainability practices using structural equation modeling. A sample of 208 amateur runners from Brazil, both male and female answered the questionnaire, with questions in a Likert scale adapted from current literature. Most participants reported a positive association between sports and sustainability, validating the proposed hypothesis. These findings provide support for additional studies on sustainability values and healthy habits, as an avenue for future research regarding consumer behavior.

The level of financial literacy of agribusiness entrepreneurs in Zimbabwe
Authors:   , Gumbo Lilian
Published: June 2023

Agribusiness is the cornerstone of the Zimbabwean economy as most people survive on agricultural related activities, and it is regarded as the first step to fighting poverty among the rural population. However, the sector has not been performing well in terms of productivity due to various factors, which include poor management of borrowed funds, higher loan defaults, and financial exclusion. The study sought to assess the level of financial knowledge, financial behaviours, and financial attitudes of agribusiness entrepreneurs. Pragmatism research philosophy guided this research. The study made use of the mixed method approach and sequential mixed method research design. Quantitative data was first collected using a questionnaire, followed by interviews that were conducted to build upon quantitative results. Multistage cluster sampling and convenience sampling were used to select research participants. The study also sought to determine the major factors affecting the financial literacy of agribusiness entrepreneurs and the nature of financial products demanded by agribusiness entrepreneurs. Research findings established that agribusiness entrepreneurs: (1) have low financial knowledge, (2) exhibit poor financial behaviours, and (3) have good financial attitudes except for diverting a portion of business loans for personal use. The general level of financial literacy was very low among agribusiness entrepreneurs but extremely low among women, lowincome earners, those with low levels of education, and those living with several dependants below 18 years. Most smallholder agribusiness entrepreneurs earned very low incomes of less than US$500 per month due to lower yields and, therefore, could not afford bank loans usually charged at very high interest rates. Agribusiness entrepreneurs usually relied on non-financial products like rotational savings (mukando in Shona), selling something owned and family and friends to make ends meet. There was a disassociation between financial products needed by agribusiness entrepreneurs and the products offered by financial institutions. The study developed and recommended a financial literacy operationalisation model for agribusiness entrepreneurs for consideration by policy makers.
Dimensions of attractiveness in employer branding and the value proposition framework for
young employees
Authors: Ružić Erik , Benazić Dragan
Published: June 2023

Purpose: The aim of this paper is to expand the body of knowledge on employer branding by identifying the dimensions of employer attractiveness for Generation Z and to develop a framework for employee value creation in the specific context of Croatian culture. Methodology: The research was conducted on a sample of 220 key informants using the scale developed by Berthon et al. (2005). Since the purpose of the paper was to identify the various dimensions of employer attractiveness as well as the key factors of attractiveness as the basis for value proposition underlying respondents’ perception of employer attractiveness, exploratory factor analysis was applied to analyze the data, i.e. a total of 25 identified employer attractiveness variables. After performing factor analysis, the average rates of importance were measured using summated rating scales for variables of individual factors. Results: The study identified six organizational attractiveness dimensions relevant to Generation Z. In addition, a value proposition framework was developed. The attractiveness dimensions encompass Organization’s market orientation, Acceptance and good relationships with colleagues, Informal characteristics of the workplace, Potential of the workplace for gaining experience and career advancement, Salary and other material benefits, and Sense of belonging to the organization. The dimensions have changed compared to the original Berthon et al. (2005) scale. These differences can be attributed to the specific needs of young employees and to a specific culture and general current conditions. Conclusion: In the “war for talent”, especially for young employees who enter the labor market for the first time, marketing concepts can be a powerful weapon. In order to attract them, their needs and wants should be deeply understood. Based on the proposed value proposition framework and the identified organizational dimensions, a valuable employer brand can be developed and the possibilities to attract and engage employees can be increased.

Published: June 2023

Terlepas dari fungsi pondok pesantren sebagai tempat untuk menimba ilmu, terkadang di pondok juga terdapat sebuah fenomena penindasan. Seperti halnya menjadikan salah satu santri sebagai bahan lelucon di depan teman-temannya. Juga terkadang menjadikannya sebagai pesuruh, bahkan dijadikan sasaran emosi. Sehingga membuat santri yang menjadi korban itu merasa takut dan tertekan. Perlakuan santri yang dapat membuat santri lain merasa tertekan baik psikis maupun fisik. Perlakuan ini biasa disebut dengan istilah bullying. Mengingat bahwa masa remaja merupakan masa yang paling banyak dipengaruhi oleh lingkungan dan teman-teman sebaya, serta dalam rangka menghindari hal-hal negatif yang dapat merugikan dirinya sendiri dan orang lain, remaja hendaknya memahami dan memiliki apa yang disebut manajemen emosi. Manajemen emosi ini terlihat dalam hal-hal seperti bagaimana remaja mampu mengendalikan emosinya setelah menjadi korban kekerasan di sekolah, apakah dapat mengelola menjadi emosi yang positif atau malah menjadi emosi negatif. Berdasarkan uraian di atas, penulis tertarik untuk melaksanakan kegiatan psikoedukasi yang tujuannya adalah untuk meningkatkan kemampuan mengelola emosi pada remaja yang tinggal di pondok pesantren Al-Muslimun agar dapat mencegah perilaku-perilaku bullying yang sering terjadi di kalangan remaja.

Global consciousness and cosmic significance of lines from Wordsworth’s poem Tintern Abbey
Authors:   Psychology Department, University of Zululand, Private Bag X1001, KwaDlangezwa 3886, South Africa, Edwards Stephen David
Published: June 2023

Mystical, panentheistic lines from Wordsworth’s poem, Tintern Abbey, constitute inductive case study material to introduce HeartMath science’s Global Consciousness Project (GCP). This case study provides a temporal dimension along which to view the cosmic significance of Wordsworth’s “felt sense”, Teilhard de Chardin’s “noosphere” and the GCP. A heuristic phenomenological method is employed. This method facilitates discussion of previous South African research with traditional healers that led to collaboration with the HeartMath Institute, based in California, and establishment of an African Global Coherence Initiative Magnetometer. This latter magnetometer is one of six GCI planetary magnetometers, with the other five currently operating in in California, Saudi Arabia, Lithuania, Canada and New Zealand. The present study introduces GCP2, an update, expanded version of the Global Consciousness Project, which complments GCI. Previously operating from the Institute of Noetic Sciences (IONS), GCP2 is now harmoniously housed by the HeartMath Institute, where its data complements both GCI and Tree Rhythm projects in amplifying interconnectedness science and global healing practices. Contemporary, endemic, planetary contexts of chaos, pollution, mindless destructiveness and war, provide urgent argument for GCP2.
Contributions of primary emissions and secondary formation to nitrated aromatic compounds in themountain background region of Southeast China

Published: June 2023

Abstract. As a major component of brown carbon (BrC), nitrated aromatic compounds
(NACs) have a significant role in the atmosphere's ability to absorb light.
However, the sources and major influencing factors of NACs in the mountain
background atmosphere are mostly lacking. Based on a thorough field
investigation of NACs from fine particle samples taken in 2014 and 2015 at
the peak of Mt. Wuyi (1139 m.a.s.l.), the current work
discussed the seasonal fluctuations in their composition, their sources, and the
important influencing factors. The total abundance of nine quantifiable NACs
increased significantly in the winter (3.9 ± 1.5 ng m−3) and
autumn (2.1 ± 0.94 ng m−3), whereas it decreased in the spring
(1.3 ± 0.75 ng m−3) and summer (0.97 ± 0.36 ng m−3).
According to the results of structural equation modeling, the majority of
NACs (93 %) were influenced by biomass, coal, and petroleum combustion
over the entire year. This work identified the origins of NACs with applying
the positive matrix factorization receptor model. The five major source
factors were biomass burning, coal combustion, secondary formation by
nitration reaction, secondary formation by photochemical reaction, and other
sources. Among them, biomass burning and coal combustion played an important
role, especially in the wintertime, with a contribution of more than 50 %.
Meanwhile, contributions from secondary formation were significant in these
remote areas, which were mainly by photochemical reaction in the summertime and
nitration reaction in the wintertime. Further analysis indicated that the
formation of NACs was comparatively sensitive to NO2 under
low-NOx conditions, suggesting that NACs would become significant in
the aerosol characteristics when nitrate concentrations decreased as a
result of emission reduction measures.

Abstract. New particle formation (NPF) and growth are a major source of atmospheric
fine particles. In polluted urban environments, NPF events are frequently
observed with characteristics distinct from those in clean environments.
Here we simulate NPF events in urban Beijing with a discrete-sectional model that couples cluster dynamics and multicomponent particle growth. In the model, new particles are formed by sulfuric acid–dimethylamine nucleation, while particle growth is driven by particle coagulation and the condensation
of sulfuric acid, its clusters, and oxygenated organic molecules (OOMs). A
variable simulation domain in the particle size space is applied to isolate
newly formed particles from preexisting ones, which allows us to focus on
new particle formation and growth rather than the evolution of particles of
non-NPF origin. The simulation yields a rich set of information including
the time-dependent NPF rates, the cluster concentrations, the particle size
distributions, and the time- and size-specific particle chemical
compositions. These can be compared with the field observations to
comprehensively assess the simulation–observation agreement. Sensitivity
analysis with the model further quantifies how metrics of NPF events (e.g.,
particle survival probability) respond to model input variations and serves
as a diagnostic tool to pinpoint the key parameter that leads to
simulation–observation discrepancies. Seven typical NPF events in urban
Beijing were analyzed. We found that with the observed gaseous precursor
concentrations and coagulation sink as model inputs, the simulations roughly captured the evolution of the observed particle size distributions; however,
the simulated particle growth rate was insufficient to yield the observed
particle number concentrations, survival probability, and mode diameter.
With the aid of sensitivity analysis, we identified under-detected OOMs as a
likely cause for the discrepancy, and the agreement between the simulation
and the observation was improved after we modulated particle growth rates in the simulation by adjusting the abundance of OOMs.
Photochemical aging of aerosols contributes significantly to the production of atmospheric formic acid

Published: June 2023

Abstract. Formic acid (HCOOH) is one of the most abundant organic acids in the atmosphere and affects atmospheric acidity and aqueous chemistry. However, the formation mechanisms of HCOOH remain poorly understood, and current air-quality models largely underestimate observed atmospheric concentrations of HCOOH. In particular, HCOOH production from condensed-phase or heterogeneous reactions is not considered in current models. In a recent field study, we measured atmospheric HCOOH concentrations at a coastal site in South China. The average concentrations of HCOOH were 191.1 ± 167.2 ppt in marine air masses and 996.3 ± 432.9 ppt in coastal air masses. A strong linear correlation between HCOOH concentrations and the surface area densities of submicron particulate matter was observed in coastal air masses. Post-campaign laboratory experiments confirmed that the photochemical aging of ambient aerosols promoted by heterogeneous reactions with ozone produced a high concentration of HCOOH at a rate of 0.185 ppb h−1 under typical ambient conditions at noon time. HCOOH production was strongly affected by nitrate photolysis, as this efficiently produces OH radicals that oxidise organics to form HCOOH. We incorporated this particle-phase source into a photochemical model and found that it explained 81 % of the peak concentration of ambient HCOOH and reproduced the diurnal variation in HCOOH concentrations. These findings demonstrate that the photochemical aging of aerosols is an important source of HCOOH that must be included in atmospheric chemistry-transport models.
Contrasting potential for biological N2-fixation at three polluted Central European Sphagnum peat bogs: Combining the 15N2-tracer and natural-abundance isotope approaches

Abstract. Availability of reactive nitrogen (Nr) is a key control of carbon (C) sequestration in wetlands. To complement the metabolic demands of Sphagnum in pristine rain-fed bogs, diazotrophs supply additional Nr via biological nitrogen fixation (BNF). Since breaking the triple bond of atmospheric N2 is energy-intensive, it is reasonable to assume that increasing inputs of pollutant Nr will lead to BNF downregulation. Yet, recent studies have documented measurable BNF rates in Sphagnum-dominated bogs also in polluted regions, indicating adaptation of N2-fixers to changing N deposition. Our aim was to quantify BNF at high-elevation peatlands located in industrialized Central Europe. A 15N2-tracer experiment was combined with a natural-abundance N-isotope study at three Sphagnum-dominated peat bogs in the northern Czech in an attempt to assess the roles of individual BNF drivers. High short-term BNF rates (8.2 ± 4.6 g N m2 d−1) were observed at Male Mechove Jezirko receiving ~17 kg Nr ha−1 yr−1. The remaining two peat bogs, whose recent atmospheric Nr inputs differed from Male Mechove Jezirko only by 1–2 kg ha−1 yr−1 (Uhlirska and Brumiste), showed zero BNF. The following parameters were investigated to elucidate the BNF difference: NH4+-N/NO3−-N ratio, temperature, wetness, Sphagnum species, organic-N availability, possible P limitation, possible Mo limitation, SO42− deposition, and pH. At Male Mechove Jezirko and Uhlirska, the same moss species (S. girgensohnii) was used for the 15N2 experiment, and therefore host identity could not explain the difference in BNF at these sites. Temperature and moisture were also identical in all incubations and could not explain the between-site differences in BNF. The N:P stoichiometry in peat and bog water indicated that Brumiste may have lacked BNF due to P limitation, whereas non-detectable BNF at Uhlirska may have been related to 70 times higher SO42− concentration in bog water. Across the sites, the mean natural-abundance δ15N values increased in the order: atmospheric deposition (−5.3 ± 0.3 ‰) < Sphagnum (−4.3 ± 0.1 ‰) < bog water (−3.9 ± 0.4 ‰) < atmospheric N2 (0.0 ‰). Only at Brumiste, N in Sphagnum was significantly isotopically heavier than in atmospheric deposition, possibly indicating a longer-term BNF effect. Collectively, our data highlight spatial heterogeneity in BNF rates under high Nr inputs and the importance of environmental parameters other than atmospheric Nr pollution in regulating BNF.
Amino acid racemization in Neogloboquadrina pachyderma and Cibicidoides wuellerstorfi from the Arctic Ocean and its implications for age models
Authors: West Gabriel , Kaufman Darrell S. , Jakobsson Martin , O'Regan Matt
Published: June 2023

Abstract. We report the results of amino acid racemization (AAR) analyses of aspartic acid (Asp)
and glutamic acid (Glu) in the planktic Neogloboquadrina pachyderma, and the benthic Cibicidoides wuellerstorfi, foraminifera species collected from sediment cores from the Arctic Ocean. The cores were retrieved at various deep-sea sites of the Arctic, which cover a large geographical area from the Greenland and Iceland seas (GIS) to the Alpha and Lomonosov ridges in the central Arctic Ocean. Age models for the investigated sediments were developed by multiple dating and correlation techniques, including oxygen isotope stratigraphy, magnetostratigraphy, biostratigraphy, lithostratigraphy, and cyclostratigraphy. The extent of racemization (D/L values) was determined on 95 samples (1028 subsamples) and shows a progressive increase downcore for both foraminifera species. Differences in the rates of racemization between the species were established by analysing specimens of both species from the same stratigraphic levels (n=21). Aspartic acid (Asp) and glutamic acid (Glu) racemize on average 16 ± 2 % and 23 ± 3 % faster, respectively, in C. wuellerstorfi than in N. pachyderma. The D/L values increase with sample age in nearly all cases, with a trend that follows a simple power function. Scatter around least-squares regression fits are larger for samples from the central Arctic Ocean than for those from the Nordic Seas. Calibrating the rate of racemization in C. wuellerstorfi using independently dated samples from the Greenland and Iceland seas for the past 400 ka enables estimation of sample ages from the central Arctic Ocean, where bottom water temperatures are presently relatively similar. The resulting ages are older than expected when considering the existing age models for the central Arctic Ocean cores. These results confirm that the differences are not due to taxonomic effects on AAR and further warrant a critical evaluation of existing Arctic Ocean age models. A better understanding of temperature histories at the investigated sites, and other environmental factors that may influence racemization rates in central Arctic Ocean sediments, is also needed.
Asynchronous glacial dynamics of Last Glacial Maximum mountain glaciers in the Ikh Bogd Massif, Gobi Altai mountain range, southwestern Mongolia: aspect control on glacier mass balance

Published: June 2023

Abstract. Mountain glacier mass balance is affected by factors other than
climate, such as topography, slope, and aspect. In midlatitude high-mountain regions, the north–south aspect contrast can cause significant
changes in insolation and melt, resulting in local asynchrony in glacial
dynamics. This study documents the asynchronous response of two
paleoglaciers in southwestern Mongolia to the local topoclimatic factors
using 10Be exposure age dating and 2D ice surface modeling. 10Be
surface exposure age dating revealed that the Ikh Artsan south-facing valley
glacier culminated (MIA1) at 20.1 ± 0.7 ka, coinciding with the global Last Glacial Maximum
(gLGM). In contrast, the north-facing Jargalant paleoglacier (MJ1)
culminated at 17.2 ± 1.5 ka, around Heinrich Stadial 1 and during the
post-gLGM Northern Hemisphere warming. Our temperature-index melt model
predicts that ablation will be substantially lower on the north-facing slope,
as it is exposed to less solar radiation and cooler temperatures than the
south-facing slope. The 2D ice surface modeling also revealed that
the south-facing Ikh Artsan Glacier abruptly retreated from its maximum
extent at 20 ka, but the Jargalant Glacier on the shaded slope
consistently advanced and thickened due to reduced melt until 17 ka. The
timing of the modeled glacier culmination is consistent within ± 1σ of the 10Be exposure age results. Extremely old ages ranging
from 636.2 to 35.9 ka were measured for the inner moraines in the
Jargalant cirque (MJ2–MJ4), suggesting a problem with inheritance
from boulders eroded from the summit plateau.

It’s Time to Bring Mental Health Literacy Education into the Postsecondary Curriculum
Authors: Zaza Christine , Yeung Ryan C.
Published: June 2023

In the last twenty years, research on post-secondary students’ mental health and well-being has grown substantially, with a dramatic increase in publications over the past decade. Likewise, concerns about declining mental health on our campuses have risen; the mental well-being of postsecondary students is now widely recognized as a major public health issue. Over the last two decades, Canadian higher education has largely addressed these concerns by promoting mental health awareness through extracurricular means. Critically, a new movement towards mental health literacy has emerged across the nation: not just supplementary outreach, but education embedded into the curriculum. To put recommendations into practice, in 2020, one of the authors [CZ] developed and taught an undergraduate course on mental health literacy with a class of 106 students. In the first offering, we conducted a pre-post study to examine if this new course would be associated with changes in mental health knowledge, stigma, and help-seeking. Of the forty students who participated in the study, ten completed measures at both the start (T1) and the end of the course (T2). Within-subjects analyses showed that students made significant gains from T1 to T2, with a large effect size, in terms of attitudes toward seeking mental health services. Feedback on the course was very positive, both in students’ ratings and their comments. Looking ahead, student well-being will depend on how institutions approach and engage with mental health literacy. We recommend firmly integrating mental health literacy education into the post-secondary curriculum.
La influencia de la obra de Vilfredo Pareto en el análisis económico moderno: ¿Un obstáculo al desarrollo de la economía de la felicidad?
Authors: Gómez-García Francisco , Ruiz-Guillermo Ángela
Published: June 2023

En este artículo destacamos la influencia profunda y duradera de Pareto en el análisis económico moderno. Ponemos el énfasis en su teoría del valor, basada en la utilidad. Este autor, en torno a 1900, inicia el giro hacia una teoría de la utilidad ordinal y objetiva. El principal objetivo de nuestro trabajo consiste en trazar el hilo conductor de ideas económicas que consideramos muy relevantes: desde Pareto hasta la economía ortodoxa actual; y desde Bentham hasta la vuelta a la felicidad como objeto de estudio de la ciencia económica, principalmente en el siglo XXI. Así, podemos afirmar que la influencia de Pareto ha perdurado, por lo menos, todo el siglo XX, retrasando bastante el resurgimiento de la economía de la felicidad. Por último, planteamos que sería muy fructífero que esta disciplina y la teoría recibida se complementaran.

Es evidente que el desarrollo de la nanociencia y la nanotecnología tendrán un impacto importante en varios campos de acción y estarán vinculadas al desarrollo de un país, por lo que su estudio es fundamental; por otra parte, la cantidad de información generada hoy en día hace difícil estudiar un tema científico. Por lo que se necesitan herramientas de análisis de información, tanto metodológicas como tecnológicas; en este contexto, las metodologías métricas son las adecuadas para estudiar un campo científico como este; por lo que el presente trabajo tiene como objetivo realizar un estudio bibliométrico sobre el desarrollo de la nanociencia y la nanotecnología en México a partir del uso del mapeo científico. Se usaron como métodos y procedimientos el análisis documental y el uso de indicadores métricos de actividad e indicadores relacionales. En el caso práctico se tomaron los datos de la Base de datos de la Web of Science y para el desarrollo de los mapas científico-tecnológicos se usó Bibliometrix. Recuperamos 15,876 artículos de investigación sobre N&N publicados entre 1975 y 2021. Los resultados preliminares muestran que recibieron en promedio 17.61 citas por artículo, los cuales fueron publicados en 2567 revistas, más del 98% de los artículos está escritos en inglés, y en cuanto a los autores existe un promedio de 5.66 por documento.

El artículo aborda la aplicación de las tecnologías de la web semántica en los archivos de televisión. Desde una perspectiva general, se plantea la implantación de los datos vinculados en los archivos audiovisuales de emisoras de televisión con el fin de optimizar y reutilizar recursos tanto para la gestión de la información como para la difusión de los productos multimedia del medio de comunicación. La propuesta se proyecta en todas las etapas de la cadena documental en dos direcciones: hacia el interior del archivo, para mejorar los metadatos, y hacia el exterior, a través de las publicaciones del medio, con el fin de evitar la dispersión de los espectadores mediante el control del acceso a segundas pantallas. Se relatan proyectos de datos vinculados desarrollados por medios de comunicación, así como por archivos audiovisuales y se proponen nuevas formas de reutilización de recursos.

Desde 2012, la igualdad entre sexos y la integración de la perspectiva de género en la investigación constituyen una de las prioridades de la Comisión Europea para la creación del Espacio Europeo de Investigación. Con el fin de erradicar la brecha de género en la investigación y la publicación científica, el Comité de Política de Género de la European Association of Science Editors (EASE) promueve las guías SAGER (Sex and Gender Equity in Research) para incorporar el informe sistemático por sexo y de género en todas las fases del proceso investigador. En nuestro país, en el proceso de evaluación de la calidad editorial y científica de las revistas españolas de la FECYT, para la obtención de la Mención de Buenas Prácticas Editoriales en Igualdad de Género, se contemplan requisitos relacionados también con la presencia de la mujer en el equipo editorial. El objetivo general de esta investigación es analizar el enfoque de género en las políticas editoriales de las revistas científicas de Comunicación del primer cuartil del Journal Citation Reports en su última edición. En concreto, se analiza la composición del equipo editorial y las instrucciones a autores/as a partir de la información disponible en las páginas web. Pese a que más de la mitad de las revistas analizadas incluyen las guías SAGER en sus instrucciones para el envío de manuscritos, la escasa visibilidad de las mismas, así como el carácter de recomendación u orientación con que se presentan en las publicaciones científicas podrían limitar su efectiva implementación.

The aim of this study is to examine classroom management skills in the context of organizational identification in educational management. Schools are the organizations that serve to meet the wishes and expectations of society in education and constitute the lowest unit of the education system. The main purpose of educational organizations is to transfer the culture and values that will ensure the continuity of society to future generations and to shape these culture and values. One of the necessary conditions for these to be realized is that students, teachers and administrators involved in educational organizations should establish a psychological connection with their organizations and all kinds of activities organized by the organization. Because identification with an organization is a form of social identification in which a person has the phenomenon of unity and a sense of belonging and bonding associated with the institution, activities and members of which he is a member. Teachers who identify with their organizations adopt and believe in organizational goals and values individually and feel motivated to achieve these goals. In these teachers, high organizational identification is achieved by adopting organizational beliefs, values, attitudes and goals. In other words, individuals with a high level of organizational identification can defend the organization in any way. As a result of organizational identification, performance increases in the organization and productivity increases, with high coordination and cooperation, the organization adapts to environmental changes easily and quickly. Thus, organizational performance increases at the expected level. The first stage of educational management that comes to mind is classroom management. Class; while it is known as the environment in which the student group actively participates in educational activities, the classroom is expressed as “A community formed by individuals whose certain qualities are the same” as the word. Examples of this are the working class, the military class, the class created in a school environment. The students in the class show closeness to each other in terms of age, level of readiness, level of knowledge. The cluster name that this cluster creates is also a class. In educational activities, the word class should also be used in this nature. The teacher quality of classroom management also depends on the impact and quality of educational management. Success in the field of education is directly related to the success of classroom management. Key Words: Educational Management, Organizational Identification, Classroom Management

In this study, it is aimed to examine the professional ethical values in private educational institutions. Although the basic staff in the education of children who require special education is a special education teacher, specially trained staff refers to a team consisting of many different areas of expertise in addition to the teacher. This team will be able to differentiate in the personnel who provide services according to the type of service required by the individual and their requirements. In this context, special education services, special education teachers, teachers assigned special education duties by traveling, guidance counselors-psychological counselors, psychologists, family doctors, audiologists, physiotherapists, parents, volunteer organization officials, primary school inspectors trained in this field, workplace representatives in institutions where individuals requiring special education work can be. Our awareness and experience of our professional actions will provide us with methods for the usefulness of our practices. However, in cases where we remain undecided, when it comes to our conflict with legal sanctions, the lack of someone to consult, even if it is impossible to get out of the business, can put us in front of some dangers. The problems in the field of special education can vary. Curriculum programs that cannot respond to the characteristics of the majority of students can raise the expectations of families, institution managers and education supervisors and cause teachers to make demands on their knowledge and responsibilities. However, staff shortages and teacher characteristics seem to be an obstacle to the formation of working and evaluation conditions that can meet the criteria in professional practices. Parents' failure to provide appropriate support to educational practices and the teacher can sometimes cause the teacher to perceive themselves as inadequate. It is very difficult for teachers to resolve such negative emotions. Because in our country, the number of supervision activities for the development of teachers is almost nonexistent.

The aim of this study is to evaluate the research findings of the individuals who immigrated to our country and their experiences in classroom environments from the point of view of teachers. Formal education in our country is carried out in closed places called classrooms in schools. The classroom is a special area created for the realization of educational goals in schools. Only Turkish citizens do not receive education within our educational structure. In addition to Turkish citizens, foreign students are also studying. Many factors, such as education management policies, the political and economic environment, the increase in anti-immigrant sentiment, demographic change, security concerns, although slow and limited in our country, have made it necessary for foreign nationals to be integrated into the education system as soon as possible. Due to the rapid increase in the number of foreign nationals, especially in large cities, every day, there is almost no class without foreign students in its class. This research was conducted in accordance with the opinions of 8 classroom teachers with at least 5 years of experience, including 4 women and 4 men who were voluntarily selected to work in the Küçükçekmece district of Istanbul province during the fall semester of the 2022-2023 academic year. In order to realize the objectives of the research, some questions were asked to the participating teachers. A number of findings were reached by analyzing the data obtained in accordance with the answers given by the participating teachers to the questions posed. After the interpretation of the findings, evaluations were made and the results of the research were reached. It has been seen that the results obtained in the research conducted within this framework and the results obtained in similar literature in our country are parallel to each other. There are a number of reasons why the classroom management experiences of teachers with foreign students in their classroom are generally realized in a negative way. Turkish language Decrees that the academic achievements of foreign students are low, their affective and intellectual motivations are insufficient, their parents' attitudes and behaviors towards them are indifferent, their access to educational tools and equipment is limited, they resort to peer bullying frequently, they cannot speak Turkish easily and properly. These reasons can be considered among these reasons. Key Words: Education Management, Migration, Classroom, Teacher, Research Findings
