La resistencia geomecánica de macizos rocosos juega un rol clave en la planificación y el diseño de proyectos de construcción civil y minera. La resistencia a la compresión uniaxial (UCS) de las rocas es una propiedad crucial que se utiliza ampliamente en ingeniería geotécnica para comprender la resistencia y deformabilidad de macizos rocosos. La determinación de las propiedades geomecánicas tanto en el campo como en el laboratorio requiere mucho tiempo, es tediosa y costosa. Sin embargo, las técnicas ultrasónicas, como la medición de la velocidad de propagación de las ondas P (VP), son un método simple, rentable y no destructivo para evaluar la UCS de las rocas. En este estudio se desarrolla una revisión del estado del conocimiento del tipo de correlaciones empíricas que existen para areniscas para predecir el valor de UCS a partir de VP. El principal objetivo desarrollado es un meta estudio sobre la relación entre UCS y VP. Para esto son recopilados desde diversas fuentes los datos de UCS y VP para roca sedimentaria tipo arenisca. Con los resultados obtenidos se proponen fórmulas empíricas que correlacionan UCS y VP, las que pueden ser usadas como una herramienta de ingeniería geotécnica para predecir el valor de UCS a partir de VP en areniscas

En la actualidad donde más residuos se producen es en la construcción a nivel mundial, generándose alrededor del 35% de residuos sólidos en el mundo y un porcentaje similar en Chile. Por cada metro cuadrado construido se producen 0.26 m3 de residuos, aproximadamente en la etapa de construcción. En la presente investigación se analizó la obra de edificación en extensión San Andrés del Valle de la constructora Aitue ubicada en la ciudad de Concepción, región del Bío Bío, Chile. Se busca desarrollar una propuesta para minimizar la pérdida de materiales, en concreto dos elementos de los más utilizados en la construcción de viviendas, como lo son las planchas de yeso cartón y perfiles de Metalcon. De esta forma, se puede optimizar los materiales mencionados, disminuir la cantidad de residuos y, por ende, tener una obra más limpia. Además, se realiza un análisis económico del ahorro generado producto de una optimización en obra de los materiales en estudio.

Algunos procedimientos que modelan los fenómenos sísmicos los consideran como eventos de naturaleza dinámica, pero existen otros que estiman una naturaleza estática. Al mismo tiempo, en ellos se puede contemplar o no, el comportamiento no lineal de las estructuras. No se puede afirmar que un procedimiento supera por completo a los otros. Pero sí se puede alegar la conveniencia de integrarlos en la práctica. En esta investigación, teniendo en cuenta los argumentos anteriores, se emplean de conjunto varios procedimientos, el Método Estático Equivalente, Método Espectro de Respuesta y Método de Registro en el Tiempo, con el objetivo de validar el análisis estructural en los elementos críticos del edificio U-142-143 construido con el sistema prefabricado Gran Panel Soviético en la ciudad de Santiago de Cuba. Luego de obtener las solicitaciones de cálculo, los elementos críticos resultaron ser los paneles exteriores transversales. En estos elementos los esfuerzos cortantes, axiales y momentos máximos, alcanzan valores superiores para el Método de Registro en el Tiempo; superando incluso los valores máximos absolutos obtenidos con la aplicación del Método Estático Equivalente. Se aprecia que son determinantes en el análisis las combinaciones de cargas que consideran acciones sísmicas predominantes en la dirección de los paneles u ortogonales a los mismos, combinadas con cargas gravitatorias máximas o mínimas. Sin embargo, la combinación de carga para la cual predomina la componente sísmica vertical no resulta dominante en el análisis. Se corrobora así mismo, un comportamiento estructural asociado a edificaciones con irregularidades en planta.

Published: December 2022

Introduction:

The emergence of novel nanobiomedicine has transformed the management
of various infectious as well as non-infectious diseases. Lasiosiphon eriocephalus, a medicinal
plant, revealed the presence of active secondary metabolites and biological potentials.

Objective:

The present study was aimed to demonstrate the biosynthesis of silver nanoparticles
using L. eriocephalus leaf extract (LE-AgNPs) and their biological properties, such as antioxidant,
antibacterial and anticancer potential.

Methods:

The biosynthesized LE-AgNPs were characterized by UV-Visible spectroscopy, Scanning
electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction, and
Fourier transform infrared spectroscopy (FTIR) analysis. The antibacterial activity was checked by
minimum inhibitory concentration (MIC) and zone of inhibition assays against Gram-positive and
Gram-negative bacteria. The anticancer potential of biogenic LE-AgNPs was checked by cytotoxicity
and genotoxicity assay against human cervical adenocarcinoma (HeLa) and human breast
adenocarcinoma (MCF-7) cells.

Results:

UV-visible spectroscopy confirmed the formation of silver nanoparticles by measuring
the surface plasmon resonance peak of the colloidal solution at 410-440 nm. The results of SEM
and TEM revealed the distribution and spherical shape of 20-50 nm sized AgNPs. XRD spectrum
confirmed the characteristic peaks at the lattice planes 110, 111, 200, 220 and 311 of silver which
confirmed the crystalline nature of biosynthesized LE-AgNPs. FTIR spectrum of plant extract and
biogenic LE-AgNPs was recorded in between 1635-3320 cm-1 which confirmed stretching vibrations
of possible functional groups C=C and O-H, responsible for the reduction of silver ions to
silver nanoparticles. The in vitro antioxidant potential of LE-AgNPs was evaluated using DPPH
(IC50 = 26.51 ± 1.15 μg/mL) and ABTS radical assays (IC50 =74.33 ± 2.47 μg/mL). The potential
antibacterial effects of LE-AgNPs confirmed that 92.38 ± 2.70% growth inhibition occurred in E.
coli in response to 0.1mg/mL concentration of LE-AgNPs followed by P. aeruginosa (75.51 ±
0.76), S. aureus (74.53 ± 1.26) and K. pneumoniae (67.4 ± 3.49). The cytotoxicity results interpreted
that the biogenic silver nanoparticles exhibited strong dose and time dependent cytotoxicity
effect against selected cancer cell lines where IC50 concentration of LE-AgNPs required to inhibit
the growth of HeLa cells after 24 h exposure was 4.14 μg/mL and MCF7 cells 3.00 μg/mL, respectively.
Significant DNA fragmentation was seen in the DNA extracted from HeLa and MCF-7 cells
exposed to more than 2.5 to 10 μg/mL concentrations of LE-AgNPs.

Conclusion:

The overall findings from the present investigation indicated that the AgNPs synthesized
using L. eriocephalus exerted strong biological potentials such as antioxidant, antimicrobial
and extensive cytotoxicity and genotoxicity activities.

E-WoM is vital in generating and creating purchase intentions, so it is significant for use in knowing and analyzing investment intentions. This research aims to analyze and know the effect of Electronic Word-of-Mouth (E-WoM) on investment intention in the capital market with brand dan trust as mediation variables. It belongs to qualitative research with an explanatory research approach. The population of this study refers to the people of Jayapura City. The sampling technique was the purposive sampling technique. The samples in this research are 203 respondents. Questionnaires collected data and analyzed using partial least squares (PLS). The results reveal that E-WoM directly affects brand image and trust. Besides, brand image and trust directly affect investment intention, while E-WoM does not directly affect investment intention. Furthermore, brand image and trust can completely mediate the effect of Electronic Word-of-Mouth (E-WoM) on investment intention and function as full mediation. The findings from this research could be applied to enhance investment intention by building customer trust and sharing the banks’ reputation and brand image through E-WoM, so they receive credible information from the bank.

The urgency of the research is that many business people understand financial literacy but seem to have less impact on financial performance. It is probably because some business people have not followed up with changes in good financial behavior. This study aims to determine the effect of financial literacy on financial behavior, financial satisfaction, and financial performance. In addition, it also knows the effect of financial behavior on financial satisfaction and financial performance and the effect of financial satisfaction on financial performance. The population in this study is the entire batik industry in Indonesia with large and medium scale, as many as 208 batik business actors. The sampling technique is a saturated sample or census, where all members of the population become members of the sample. The data analysis technique used SMART PLS 03 software. According to the study’s findings, financial literacy has a significant effect on financial behavior and financial performance, and financial behavior significantly affects financial satisfaction. Financial satisfaction furthermore has a significant effect on financial performance. However, financial literacy has no effect on financial satisfaction, and financial behavior has also been found to have no effect on financial performance. This research implies that the financial performance of batik industry players will increase if they have financial behavior that can create added value and the importance of financial literacy.

The study investigates the iGen customer loyalty model that is affected by service quality, culture, loyalty program, and trust through customer satisfaction. Following the conceptual model, an inclusive set of hypotheses have been developed. The needed data were collected from 663 samples using an online survey, and Structural Equation Model with Smart Partial Least Square was applied to test the model and hypotheses. The research found that service quality, culture, loyalty programs, and trust are combined to predict customer loyalty. Trust and loyalty programs exert a more powerful impact on customer loyalty than service quality and culture variables. Customer satisfaction is a mediator between service quality, loyalty programs, customer trust, and customer loyalty. The results have some critical academic and professional implications for determining the model of consumer loyalty and the uniqueness of internet generation (iGen) in mobile communication services. The study can be used as a role model in formulating a marketing strategy management with a competitive advantage in mobile communication services in Indonesia.
Democratic equality and Rawls’s criticism of welfare state capitalism
Authors: Fernández Manzano Juan Antonio
Published: December 2022

Despite the accusation of developing an abstract theory, detached from real conditions, depoliticizing, and ultimately inclined towards the status quo, Rawls did not fail to analyze, since 1971, the political-economic conditions in which his theory could become viable. The analysis of this topic concludes with the statement that the principles and ideals of his theory could not be satisfied under capitalism in any of its forms. This article discusses the possibilities of making justice as fairness compatible under a capitalist welfare state and shows that the reasons Rawls presented for denying this possibility remain perfectly valid. The difficulties of a capitalist welfare state to curb the tendencies of capitalism towards undemocratic inequality make this system unacceptable. The article defends that, although it is a noble ideal to prevent anyone from falling below a certain social minimum, the requirements of the principles of justice are much more demanding. The article concludes by defending Rawls's methodology and main arguments and shows that far from having depoliticizing effects, justice as fairness allows us to broaden the political imagination both to denounce the highly oligopolistic character of capitalist economies and to combat the ubiquitous inclination of neoliberalism towards economic efficiency as an all-encompassing value.

A Spatiotemporal Solution to Control COVID-19 Transmission at the Community Scale for Returning to Normalcy: COVID-19 Symptom Onset Risk Spatiotemporal Analysis
Authors: Tong Chengzhuo , Shi Wenzhong , Zhang Anshu , Shi Zhicheng
Published: December 2022

Background

Following the recent COVID-19 pandemic, returning to normalcy has become the primary goal of global cities. The key for returning to normalcy is to avoid affecting social and economic activities while supporting precise epidemic control. Estimation models for the spatiotemporal spread of the epidemic at the refined scale of cities that support precise epidemic control are limited. For most of 2021, Hong Kong has remained at the top of the “global normalcy index” because of its effective responses. The urban-community-scale spatiotemporal onset risk prediction model of COVID-19 symptom has been used to assist in the precise epidemic control of Hong Kong.

Objective

Based on the spatiotemporal prediction models of COVID-19 symptom onset risk, the aim of this study was to develop a spatiotemporal solution to assist in precise prevention and control for returning to normalcy.

Methods

Over the years 2020 and 2021, a spatiotemporal solution was proposed and applied to support the epidemic control in Hong Kong. An enhanced urban-community-scale geographic model was proposed to predict the risk of COVID-19 symptom onset by quantifying the impact of the transmission of SARS-CoV-2 variants, vaccination, and the imported case risk. The generated prediction results could be then applied to establish the onset risk predictions over the following days, the identification of high–onset-risk communities, the effectiveness analysis of response measures implemented, and the effectiveness simulation of upcoming response measures. The applications could be integrated into a web-based platform to assist the antiepidemic work.

Results

Daily predicted onset risk in 291 tertiary planning units (TPUs) of Hong Kong from January 18, 2020, to April 22, 2021, was obtained from the enhanced prediction model. The prediction accuracy in the following 7 days was over 80%. The prediction results were used to effectively assist the epidemic control of Hong Kong in the following application examples: identified communities within high–onset-risk always only accounted for 2%-25% in multiple epidemiological scenarios; effective COVID-19 response measures, such as prohibiting public gatherings of more than 4 people were found to reduce the onset risk by 16%-46%; through the effect simulation of the new compulsory testing measure, the onset risk was found to be reduced by more than 80% in 42 (14.43%) TPUs and by more than 60% in 96 (32.99%) TPUs.

Conclusions

In summary, this solution can support sustainable and targeted pandemic responses for returning to normalcy. Faced with the situation that may coexist with SARS-CoV-2, this study can not only assist global cities in responding to the future epidemics effectively but also help to restore social and economic activities and people’s normal lives.

Authors: Mourali Mehdi , Benham Jamie L , Lang Raynell , Fullerton Madison M , Boucher Jean-Christophe , Cornelson Kirsten , Oxoby Robert J , Constantinescu Cora , Tang Theresa , Marshall Deborah A , Hu Jia
Published: December 2022

Background

Adherence to nonpharmaceutical interventions for COVID-19, including physical distancing, masking, staying home while sick, and avoiding crowded indoor spaces, remains critical for limiting the spread of COVID-19.

Objective

The aim of this study was to test the effectiveness of using various persuasive appeals (deontological moral frame, empathy, identifiable victim, goal proximity, and reciprocity) at improving intentions to adhere to prevention behaviors.

Methods

A randomized online experiment using a representative sample of adult Canadian residents with respect to age, ethnicity, and province of residence was performed from March 3 to March 6, 2021. Participants indicated their intentions to follow public health guidelines, saw one of six flyers featuring a persuasive appeal or no appeal, and then rated their intentions a second time. Known correlates of attitudes toward public health measures were also measured.

Results

Intentions to adhere to public health measures increased in all appeal conditions. The message featuring an empathy appeal resulted in a greater increase in intentions than the control (no appeal) message. Moreover, the effectiveness of persuasive appeals was moderated by baseline intentions. Deontological, empathy, identifiable victim, and reciprocity appeals improved intentions more than the control message, but only for people with lower baseline intentions to adhere to nonpharmaceutical interventions.

Conclusions

Public health marketing campaigns aiming to increase adherence to COVID-19 protective behaviors could achieve modest gains by employing a range of persuasive appeals. However, to maximize impact, it is important that these campaigns be targeted to the right individuals.

Authors: Kim Ga-Young , Yun Hee Jung , Jo Mini , Seol Hye Yoon , Jo Seoyoung , Cho Young Sang , Hong Sung Hwa , Moon Il Joon
Published: December 2022

BACKGROUND

Hearing aids (HAs) are regarded as the gold standard for hearing loss (HL) management, however, the adoption rate of HAs is relatively low for various reason. Recently, several smart device manufacturers have been facilitating a drive to increase accessibility, so that users can leverage their products for their healthcare.

OBJECTIVE

The aim of the study was to evaluate the clinical efficacy of Apple AirPods Pro with the Headphone Accommodation feature as a hearing assistive device in patients with mild to moderate HL.

METHODS

Fifteen participants (seven men and eight women) with mild to moderate HL recruited. Pure-tone audiometry (PTA) were used for screening HL. AirPods Pro paired with iPhone running iOS 15.6 was used for the study. Three hearing tests were administered both in the aided and unaided conditions in the free sound-field: 1) functional gain; 2) word recognition score (WRS); and 3) sentence recognition in noise. The Wilcoxon signed-rank test was used to compare between the aided and unaided conditions outcomes.

RESULTS

For the functional gain, there were significant differences between the aided and unaided conditions at frequencies of 250 Hz (P = .013), 500 Hz (P = .001), 1000 Hz (P = .001), 2000 Hz (P = .001), and 6000 Hz (P = .022). The WRS showed a significant difference between the aided and unaided conditions (P = .001). The sentence recognition in noise demonstrated a significant difference between the aided and unaided conditions (p = .003)

CONCLUSIONS

: AirPods Pro with Headphone Accommodation feature have the potential to help patients with HL improve their hearing and speech recognition even under noisy conditions. However, as the gain of the overall frequency is not sufficient, it might be more suitable for patients with mild to moderate HL.
Proxy Wars and the Dilemma of Global Peace: Interrogating the Roles of the Super Powers (1946-1991)
Authors: Onyekwuma Ebie Sunday
Published: December 2022

The end of the Second World War brought about the emergence of two super powers, the United States and the Soviet Union that assumed major key players in global Politics. The two superpowers adopted expansionist policies in their attempt to build alliances so as to implement and protect their diverse ideological interests. In the process, proxy wars ensued in different part of the globe. Adopting secondary source of data and Content Analysis as well as Power Theory, the paper examined the roles of the super powers in proxy wars and the consequences on global peace. The paper discovered that the Super-powers dominated the global political system through proxy wars such as the Vietnam War, Korean War and the Cuba Missile Crisis among others. The paper further noted the consequences of proxy war on global peace to include arms proliferations and the development of nuclear weapons, high human fatalities and destruction of major cities and the rise in global terrorist groups and attacks. The paper made recommendations among others that global ideological rigidity should be softened to accommodate varieties and the United Nations should give more attention to the situation in Korea Peninsula to prevent the repeat of the 1950s.

Published: December 2022

Soil organic carbon (SOC) plays an important role in soil fertility and is of paramount importance for its contributions to mitigation and adaptation to climate change. The present study was undertaken to estimate the SOC stock and soil properties in important plantations of the Southern zone in Tamil Nadu. Four different species were selected for the study viz, Eucalyptus, Casuarina, Melia and Teak. In all the plantations selected for estimation of biomass, composite soil samples were collected at three different depths; i.e., 0-15, 15- 30 and 30-45 cm. The soil samples were analysed for the carbon stock and various properties such as pH, Electrical conductivity, Organic carbon, Available N, Available P, Available K. Among Eucalyptus plantations, clonal plantation of >6 years sequestered the highest amount of soil carbon (19.8 Mg ha-1) at 30 cm depth. SOC stock was maximum in Casuarina plantation of > 5 years (23.3 Mg ha-1). Among the different Melia plantations, maximum SOC stock was observed in Melia plantation of 5 to7 years old (15.6 Mg ha-1), and in Teak plantations, SOC stock was highest in plantations of > 15 years old (22.1 Mg ha-1). The soil pH and Electrical conductivity significantly differed among the plantations and decreased with an increase in the age of plantation. Nitrogen availability was highest (303.98 kg ha-1 ) in >5 years of Casuarina clonal plantation at 0-15 cm depth. Among the plantations the available potassium was high in surface soils (0-15 cm) of >5 years Casuarina clonal plantation (329.50 kg ha-1). The data generated in the present study would provide valuable information on the scope of afforestation and reforestation projects for sustaining the livelihoods of the farming community and also will encourage them to contribute to mitigating global carbon emissions and expanding forest and tree cover.

Published: December 2022

Abstract: Cutting fluids has greater significance in manufacturing processes to ensure work-piece quality, to reduce tool wear, and to improve process productivity. The specific chemical composition of an applied coolant should be strongly dependent on the scope of application. Even small changes such as presence of microorganisms such as Staphylococcus, Streptococcus, Pseudomonas, Alcaligenes etc. can influence the performance of cutting fluid and introduce risk of various skin diseases to the operator in the manufacturing processes considerably. In this project the antibacterial coating is brought into use by coating a thin layer of silver nano particles on a polypropylene filtration membrane. A coated and non-coated membrane was placed separately on the cutting fluid sump of a vertical milling machine. 10litres of cutting fluid with a Servo cut Soil content of 5% and distilled water with a concentration of 95% were used in the machine while a milling process was carried out. Then a sample of cutting fluid (about 250mL) was taken from the tank and preserved for testing purposes after passing through the filter membranes. On the same cutting fluid, the machine was run for another two days, and a third sample was taken at the end of the fourth day. The samples collected were tested at Azyme Biosciences Pvt Ltd for bacterial count (CFU/ml) and the results showed that the CFU/ ml in the sample filtered through the non-coated polypropylene filtration membrane was higher than in the sample filtered via coated polypropylene filtration membrane.

Authors: Akhter Farzana , Quamri M. A. , Yousf Nasir
Published: December 2022

Diffuse Hair loss (DHL) is an excessive loss of hair from all over the scalp without producing any bald spots, inflammation or scarring. It is the result of disruption of one phase of the hair cycle. According to Unani system, the term used is Intithār al-Sha‘r. Various Unani scholars like Dioscorides, Ibn Māswayh, Zakariyyā Rāzī, Ali Ibn Abbas Al-Majūsī, Ibn Sīnā described Intithār al-Sha‘r in detail with its etiopathogenesis and management in their treatises. They stated that the most common cause is poor production of bukhārāt-i-dukhānīyya, leads to poor gathering in the masamaat (Skin pores), thus, producing yābusat in the whole body. This yābusat alter the normal structure of body’s skin, make it extremely thin and loose. So, hair comes out easily when gently pulled, resulting in hair thinning and shedding. The purpose of this review is to highlight the concept of Diffuse Hair Loss in Unani system with its treatment as mentioned in classical Unani books.

Development and Initial Validation of an Assessment Tool for Student Transversal Competences
Authors:   University of Latvia, Dimdiņš Ģirts , Miltuze Anika , Oļesika Alise
Published: December 2022

Transversal competences have been receiving an increasing attention in educational research and practice over the last decades. As a part of a wider project for assessment of students’ competences in higher education, a group of experts developed a model of transversal competences for students, consisting of civic, digital, entrepreneurial, global, innovation, and research competences (each with corresponding sub-competences and facets), based on the analysis of theory and previous research. In this paper, we present an assessment tool that was developed and tested for measurement of the competences in this model. The final version of the assessment tool is a self-report survey with 292 behavioural indicators that are evaluated on a 7-point Likert-type scale estimating how characteristic each indicator is of the respondent’s typical behaviour. The initial pool of behavioural indicators was created by the same group of experts based on the analysis of previous research and best practice examples in transversal competence assessment. From this pool, an initial version of the survey with 440 indicators was created and administered to 686 respondents from 8 study domains representing all study levels. Factor analysis of responses revealed a six-factor structure corresponding to the initial theoretical competence model. After further psychometric analysis, the final version of the assessment tool was formulated. Each of the six competences is further divided into 3–5 sub-competences, with each sub-competence consisting of 2–5 facets. Each facet is measured with multiple behavioural indicators describing basic, intermediate and advanced level of the respective competence. The results showed good construct validity of the tool, with the expected competence differences appearing between different study levels, and the expected relations emerging between the competence indicators and average grades. Practical applications and possibilities for further development of the assessment tool are discussed.

Published: December 2022

Successful cooperation and collaboration between teachers and school parents are essential for the development of students, their successful learning process, and academic achievements. This cooperation and collaboration between teachers and parents are essential to creating it successfully, setting responsibilities and rights for each educational partner. Important question- how to build this cooperation respectfully and engage students in this cooperation to reach academic success and educational objectives mentioned in educational documents. The Qridi education program, created in Finland, is a tool for promoting teacher cooperation with school parents that saves teachers’ time in communicating with their parents. The program is based on a teacher’s planned and supervised training process, through regular school evaluations, students’ self-assessments, and learning to observe the work of another classmate, which is also available to parents, and through continued training at home, parents can continue the school teaching process. The purpose of the study is to assess the Qridi program’s effectiveness in teacher collaboration with parents.

International research reports have indicated inequality risks for students’ future success due to COVID-19 pandemic, including risk of dropping out of school and risk of learning losses. Group differences in students’ skills and opportunities have been revealed way before pandemic, and the pandemic itself can contribute as a facilitating factor for the increase of these differences. In this research 952 students in the 9th grade were assessed during distance learning in Latvia. Data were analysed regarding group differences, as well as students’ decisions about continuing education after the primary school. Results show that: 1) Students who had participated in individual face-to-face consultations showed lower verbal and nonverbal reasoning skills, lower grades in four previous study semesters, and had parents with lower education compared to students who had not participated in individual consultations, indicating the importance for such individual support mechanisms for the students facing difficulties; 2) Students with lower parental education level had lower average grades in four previous semesters, lower verbal reasoning and nonverbal reasoning abilities, self-management and problem-solving skills; 3) Girls had higher average grades in all four consecutive semesters and higher problem-solving and self-management skills, compared to boys; 4) Pandemic affected students’ decisions about continuing studies after the 9th grade mostly for those students who had thought about changing the school or the location of school.

While involved in scientific research activities, pupils get acquainted with the methods and structure of scientific research, thus acquiring skills necessary to handle and develop theoretical concepts, carry out empirical analysis, develop analytical and critical thinking and acquire new knowledge and skills. Expert-accessor analysis of the pupils’ papers presented between 2017–2022 in the national competition of research papers in foreign language and literature studies has allowed the detection of distinct categories of mistakes appearing in numerous papers that prevent even very talented pupils from achieving good results. Thus, the study aims to promote the understanding of both pupils and teachers supervising research papers of the most common mistakes that should be avoided while elaborating a research paper and stimulating the creation of more successful research papers in the future. The report provides a summary of data obtained by analysing 27 pupils’ research papers submitted in the Riga region and reviews of these works, identifying the most common types of errors and how they affect the results, as well as providing recommendations on how to eliminate such errors. The study concludes that the three most important groups of errors are related to an inappropriate selection of the research field, inability to formulate and prove the topicality and novelty of the research, and failure to balance, structure, and harmonize the research carried out in the theoretical and empirical parts of the paper. The obtained results indicate that it is necessary to educate further supervisors, pupils, researchers, and prospective teachers on how to avoid these mistakes to improve the quality of the research in the field of literary studies, so suggestions are provided at the end of the paper.

Published: December 2022

Rapid technological development and information overload has shaped the identity of the 21st century and has had an immense impact on many social aspects of human life including education systems and children across the world. In their early years, children experience rapid flows of information and a vast range of emotional stimuli every day which, without the ability to effectively self-regulate the emotional responses to these stimuli, can cause anxiety, cognitive overload, socialisation problems and uncontrollable emotional release, resulting in psychological distress for everyone involved – children, parents, and educators. Furthermore, in early childhood education long-term implications must always be considered as, during such overwhelming moments, a child is not able to effectively engage in socialisation or learning processes and subsequently, this can have a negative effect on overall long-term development and the life of a child. This research confirms that, in the past decade, social emotional learning has, for many education institutions across the world and systems worldwide, become an integral part of learning. Nevertheless, in early childhood education research, there remains a notable knowledge gap concerning the lack of systematized knowledge and practical tools to support the development of emotion regulation skills in early childhood education. This paper presents a theoretical and qualitative multi-method study, including a pedagogical intervention, providing scientifically grounded answers and practical advice for educators and early childhood education institutions on how to integrate mindfulness praxis to promote emotion regulation skills of children aged five to six. The results of the research show that meaningful and qualitative support of emotion regulation skills development are provided, through the inclusion of mindfulness praxis as a purposeful and systematic part of early childhood education.

Cultural literacy today is an important educational outcome in the context of individual identity, civic education and multiculturalism. It allows an individual to understand and respect themselves, their culture and the diversity of the other cultures, know the origins, and connotations. Cultural literacy as a result of education is related to two ideas: how to live meaningfully, consciously in society and the cultural environment, how to take responsibility for cultural heritage and values ​​and create cultural values ​​for oneself. Traditional celebration and rituals are an important phenomenon in traditional culture. In the rituals, society has encoded the main world scenes and patterns of human behavior that have contributed to the well-being of the collective and the individual. The attachment of a ritual to a specific point in time and space is one of the most important conditions for its existence. Eternity and infinity are too vague abstractions for the limited human imagination. In order to understand the world we live in, these abstractions are saturated with reference points, markers. To master the content of traditional celebration means to orient oneself in these spatial and temporal markers, to know the participants of the ritual, their roles and functions, at the same time offering to experience those aspects of the ritual in which the experience cannot be explained only by rational thought processes. In this article the components of the content of the traditional cultural calendar celebration from the point of view of the ritual were substantiate. Recommendations for the implementation of traditional culture content in primary education are offered.

Sustainability has been a topical issue for more than 20 years not only dealing with environmental/ecological, social/cultural and economic issues. Combining social, economic, and environmental initiatives in education is a complex process that should result in a completely new vision of educational institutions. It raises the necessity for a management structure to encourage and support the sustainability initiatives within the organisation. The article deals with one aspect of a larger scale and long-term grounded theory research to explore and define the concept of a sustainable team in educational institution. This article answers the research questions on how students are seen and perceived in the education management hierarchy of an educational institution, and what fosters the development of sustainable team in an educational institution. The data were collected by the content analysis of the education management hierarchy structure reflected on 33 homepages of educational institutions; content analysis of 62 students’ teaching practice assignments on the education management hierarchy structure; 12 interviews with school administration on the state of the art of sustainable team. Research sample was 107 educational institutions: 23 primary schools, 66 secondary schools, and 18 state gymnasiums with broad geographical representation – the schools in the capital, cities, small towns, and countryside. Sustainable team achieves institutional goals and cultivates a culture where collaboration, appreciation, and teamwork are valued. According to the data of the study, there is a misunderstanding of the notion of a sustainable team in educational institutions in Latvia. There is also a lack of evidence of students as meaningful players in how the education management hierarchy is seen and interpreted which slows down the implementation of the sustainability initiatives.
Some Aspects of Teaching Latvian Grammar at School

Published: December 2022

The Latvian language as a subject has been a taught language since the 1st grade till 12th grade in both minority schools and schools, where the Latvian language is the language of instruction. In recent years the country has also been implementing the education reform within the framework of which the content and its acquisition methodology has been improved, but the students’ level of the Latvian language as state language skills is declining in various aspects. The topicality of the problem to be researched stems from the results obtained by analyzing the scientific research implemented in the country (2007–2021) and other research on language competence of basic and secondary education students. The aim of the research is to analyze the content and methodology of grammar teaching in basic school and in secondary school for students’ language competence. The methodology of the study is based on linguistics, linguistic didactics, cognitivism and sociocultural theories. The empirical data have been obtained by analyzing the Latvian language learning process and the quality of the essays (content analysis of 409 essays of the 12th grade secondary school students in School Year 2018/2019 according to the previously developed criteria based on theories). The results of the research show that students learn the grammar rules mainly formally, without linking them to a specific communicative purpose. More attention should be paid to students’ work with authentic texts, pupils’ own texts as well as study texts used for the acquisition of the content of other subjects. In the didactics of the Latvian language more attention should be paid to the students’ sense of language as the ability to perceive, emotionally recognize and evaluate the use of language. The significance of the results lies in the aspect that they reveal the real situation and enable us to develop recommendations for the improvement of the Latvian language learning process.
