To effectively locate the organic crop production by regions of Rus sia, a methodology has been developed. It includes the development of a database for calculating a system of indicators of the conditions for the production and consum ption of organic products. The indicators are selected using the expert method. They characterize the regions in terms of the potential for socioeconomic development; the state of agriculture; climatic and ecological conditions; the standard of living of the population that forms the demand for organic products. The methods o f Factor and Cluster analysis are the basis of the methodology. Based on the results of the Factor analysis, five components were identified for each group of indicators that formed the basis for the typification of regions. The method of Cluster analysis identified seven groups (clusters) of regions, differentiated according to the conditions that form the potential for the develo pment of organic production. Approaches to the location of certain types of crop production are proposed for each cluster. Efficient location of production is justified by taking into account the climatic conditions important for crop pro duction, consumer demand and the ability to supply the population within each group of regions. The authors tested the methodology for the regions of Russia, which allowed not only to ident ify the conditions most favorable for the organic production, but also to give recommendations on crops for growing in these territories.

In this retrospective observational study, we analysed a community outbreak of impetigo with meticillin-resistant Staphylococcus aureus (MRSA), with additional resistance to fusidic acid (first-line treatment). The outbreak occurred between June 2018 and January 2020 in the eastern part of the Netherlands with an epidemiological link to three cases from the north-western part. Forty nine impetigo cases and eight carrier cases were identified, including 47 children. All but one impetigo case had community-onset of symptoms. Pharmacy prescription data for topical mupirocin and fusidic acid and GP questionnaires suggested an underestimated outbreak size. The 57 outbreak isolates were identified by the Dutch MRSA surveillance as MLVA-type MT4627 and sequence type 121, previously reported only once in 2014. Next-generation sequencing revealed they contained a fusidic acid resistance gene, exfoliative toxin genes and an epidermal cell differentiation inhibitor gene. Whole-genome multilocus sequence typing revealed genetic clustering of all 19 sequenced isolates from the outbreak region and isolates from the three north-western cases. The allelic distances between these Dutch isolates and international isolates were high. This outbreak shows the appearance of community-onset MRSA strains with additional drug resistance and virulence factors in a country with a low prevalence of antimicrobial resistance.

Introduction

Meat can be a vehicle for food-borne transmission of antimicrobial resistant bacteria and antimicrobial resistance genes. The occurrence of extended‐spectrum beta‐lactamase (ESBL) producing Enterobacterales has been observed in meat from livestock production but has not been well studied in meat from wild game.

Aim

We aimed to investigate, particularly in central Europe, to what extent ESBL-producing Enterobacterales may be present in wild game meat.

Methods

A total of 111 samples of different types of game meat supplied by butchers, hunters, retail stores and a large game-processing establishment in Europe were screened for ESBL-producing Enterobacterales using a selective culture medium. Isolates were genotypically and phenotypically characterised.

Results

Thirty-nine samples (35% of the total) yielded ESBL-producing Enterobacterales, with most (35/39) supplied by the game-processing establishment. Isolates included 32 Moellerella wisconsensis, 18 Escherichia coli and one Escherichia marmotae. PCR screening identified bla
CTX-M-1 (n = 31), bla
CTX-M-32 (n = 8), bla
CTX-M-65 (n = 4), bla
CTX-M-15 (n = 3), bla
CTX-M-8 (n = 1), bla
CTX-M-14 (n = 1), bla
CTX-M-55 (n = 1), and bla
SHV-12 (n = 2). Most E. coli belonged to phylogenetic group A (n = 7) or B1 (n = 9), but several isolates belonged to extraintestinal pathogenic E. coli (ExPEC) sequence types (ST)58 (n = 4), ST68 (n = 1) and ST540 (n = 1). Whole genome sequencing of six selected isolates localised bla
CTX-M-1 on megaplasmids in four M. wisconsensis and bla
CTX-M-32 on IncN_1 plasmids in one M. wisconsensis and one E. marmotae. Forty-eight isolates (94%) exhibited a multidrug-resistance phenotype.

Conclusion

We found a high occurrence of ESBL-producing Enterobacterales in wild game meat, suggesting wildlife habitat pollution and possible microbial contamination events occurring during skinning or cutting carcasses.

Published: December 2022

The effect of concentrations of 25 chemical elements in wool on the quantitative and qualitative characteristics of sperm was studied in Holstein sires (n = 55), age 3-4 years, in the conditions of JSC "Nevskoye" by breeding work in Leningrad region. Wool samples were collected from the top of the withers and determined by the AES-ISP method. The interrelation of quantitative and qualitative characteristics of the sperm was revealed with two chemical elements: calcium and aluminum. Thus, as the calcium concentration in wool increases from 604±194.8 mg/kg to 3690±460.3 mg/kg, the volume of native sperm increases by 55.8% (P?0.01), spermatozoa activity increases by 0.14 points (Р?0.05), diluted semen yield – by 95.1% (Р?0.01), number of frozen doses – by 82.6% (Р?0.05). An increase in aluminum concentration from 1.89 mg/kg to 8.46 mg/kg is accompanied by a decrease in the concentration of spermatozoa by 20.4% (P?0.001), activity - by 0.21 points (P?0.05), number of frozen doses - by 55.4% (P?0.01).
A cultural apocalypse: Apocalyptic impacts of imperialism in E. M. Forster’s A Passage to India
Authors: ÖZÇELİK Kaya
Published: December 2022

First emerged as a religious term to designate the end of the world, the idea of apocalypse has evolved into manifold connotations that is associated with any cataclysmic event(s) and case(s) that end(s) up with the complete destruction of the present state with a new beginning. Although it is more often affiliated with the destruction(s) caused by climate crisis and advancements in science and technology, the destruction of a culture through cultural clash(es) between two opposing cultures, namely the East and West, and the results out of these that dehumanise the representatives of the weaker side/East can also be included in the analysis of apocalypse in a broader sense in the context of culture. It is within this focus of interest that E. M. Forster’s masterpiece A Passage to India (1924) has been evaluated as an example for the cultural apocalypse throughout the research, as a result of which the Indians - even their country - is plunged into total apocalypse and become subservient and considered nothing rather than a swine. Controlled under a civil station and isolated from the luxury and comfort the British are free to relish, Indians are drawn as character who are bereft of any freedom and respect from the British in their own land. Thus, the economic and political causes behind the ideology of imperialism that is also intertwined with capitalism in India have been considered as major consequences of the cultural clash that arise as a cultural apocalypse in the lives of native Indians.

Published: December 2022

The present review asessessed meat quality taking into account complex and multivariate qualities including meat production. Production conditions; however, consist of management system, breeding, genotype, feeding, holding and stunning before slaughtering, method of slaughter, cooling and storing conditions. Meat quality changes depending on many factors such as feed, level of feeding, weaning age, castration, slautering age, etc. Today, animal nutritionists have developed new nutrition strategies to improve meat quality by changing the feed composition of poultry and small/large ruminant. Also, animal nutrition can affect gene expression in the animal via epigenetic effects varying the differentiation and proliferation of adipose cells. Scientists can use different feedstuffs to modulate the expression of target genes and increase meat quality.

Published: December 2022

15.yüzyılda, Çağatay edebiyatının mihenk taşı şairi olan Ali Şir Nevȃyî, Türkçe divanlarındaki şiirlerinde insanın içsel yolculuğundaki varoluşu ve anlamı keşfedebilmesinde tasavvufun incelikli felsefesine başvurmuştur. İnsan yaşamı hakkında felsefî görüşlerini şiirlerinde ele alırken bazı özel kuş adları vasıtasıyla tasavvufî ve edebî anlamda farklı bir anlatım sergilemiştir. Bunun yanı sıra Nevȃyî’nin beyitlerindeki özel kuş adlarına metaforik bir kullanımla yer verdiği görülmektedir. Bu makale iki bölümden oluşmaktadır. Makalenin ilk kısmında metafor kavramı hakkında kısa bir bilgi verilmiştir. Makalenin ikinci kısmında, Nevȃyî’nin Türkçe divanlarındaki özel kuş adlarının geçtiği beyitler gösterilmiştir. Özel kuş adlarının yer aldığı beyitlerdeki bazı kavramların birtakım tasavvufî kavramlarla ve Kur'an-ı Kerim'deki bazı ayetlerle bağlantılı olarak oluştuğu görülmektedir. Bu özel kuşların kurduğu bağ Nevȃyî’nin kuş dünyasını da şekillendirmiştir.

Nevȃyî'nin kuş dünyasını şekillendiren bu özel kuşlar insanlığa yol gösteren bir rehber gibi tasavvur edilmiştir. Bu özel kuşlar manevî yolculukta hem yolunu bulmaya çalışan bir mürit gibi hem de yol gösteren bir mürşit gibidir. Türkçe divanlardaki özel kuşlardan bazıları Nevȃyî’nin “Lisânü’t-Tayr” adlı eserinde manevî yolculuğa çıkan otuz kuş gibi eşlik ettiği görülür. Ayrıca Türkçe divanlardaki bu özel kuşlardan bazılarının Nevȃyî’nin “Lisȃnü’t-Tayr” adlı eserinde yer verilen bazı özel kuşlarla olan ilişkisi ve farklı yönleri üzerinde durulacaktır.

A lógica do capital e seus reflexos sobre as políticas de formação continuada dos professores da educação básica
Authors: Mata Áurea Augusta Rodrigues da
Published: December 2022

O artigo trata das políticas educacionais, precisamente, a política de formação continuada dos professores da educação básica nacional e no Estado de Pernambuco. No Estado estão inseridas no Programa Pacto Pela Educação, tido pelo governo como política pública de impacto social e colocado no âmbito dos temas estratégicos para desenvolvimento do Estado. Realizamos análise do ordenamento legal nacional e estadual e do ordenamento curricular estadual que tratam da temática e percebemos que as políticas estão pautadas pela lógica do capital, tendo por base a política de responsabilização que agrega meritocracia e gerencialismo, com foco nas avaliações externas, nos índices educacionais e distribuição de bônus - o que acaba por operacionalizar uma desqualificação do trabalho docente e da escola, representando a manutenção e reprodução das relações sociais dominantes, ligadas à teoria do capital humano, travestido de defesa do direito de aprender. Por fim, reafirmamos a defesa de uma demanda histórica da categoria por política de formação e de valorização dos profissionais, capaz de articular formação inicial e continuada, com condições básicas de trabalho, articulada com a luta mais geral da política educacional no país, a partir de referências que coloquem a educação para além da lógica do capital.

Published: December 2022

A Nova Gestão Pública surge como um modelo de gestão da coisa pública que se pauta no viés gerencialista, tendo como objetivo tornar o Estado mais eficiente, eficaz e econômico, assim como, fomentar espaços de maior participação e responsabilização na busca de resultados. A NGP vem se consolidando como base para a reestruturação dos sistemas. Pernambuco promove uma formação para os gestores escolares de sua rede que materializa uma gestão baseada na cultura dos resultados, na meritocracia e na bonificação. O estudo se baseia na Análise Social do Discurso. De acordo com Fairclough (2001), o estudo busca compreender de que forma o discurso estrutura as relações de poder na sociedade, considerando o discurso como prática social. A pesquisa apresenta como o governo de Pernambuco faz uso dos mecanismos do discurso para atrelar o processo de participação dos professores, num curso de formação de gestores escolares, em um instrumento para construir a qualidade da educação na rede pública, numa perspectiva gerencialista. Essa discussão se apresenta em contextos relevantes, na medida em que está se vivenciando o panorama das avaliações externas como único meio de aferição da qualidade da educação na forma dos índices educacionais. O estudo analisa a estrutura do programa, as medidas adotadas para a educação no tocante às avaliações externas e o quanto este panorama tem reverberado na organização da gestão escolar.

Published: December 2022

A formação de professores requer um olhar sobre a concepção de educação; as instituições formadoras, a docência universitária e a articulação entre ensino, pesquisa e extensão. Deve contemplar princípios da ética e autonomia, na construção de uma prática contextualizada que desenvolva as potencialidades do educando, para o exercício da profissão docente e da cidadania numa perspectiva Interdisciplinar e planetária. A formação dos educadores do campo requer um olhar sobre a identidade dos sujeitos do campo, a cultura local, os contextos e a sustentabilidade. O processo de formação deve mobilizar saberes científicos, técnicos, pedagógicos e possibilitar o diálogo intercultural. Neste artigo temos por objetivo analisar a formação de educadores do campo no âmbito do PRONERA, no curso de Licenciatura em Geografia do Campus Mata Norte, através da curricularização da extensão universitária com base na Pedagogia da Alternância. A pesquisa de abordagem qualitativa foi desenvolvida para analisar as atividades realizadas pelos educandos no tempo-comunidade. Recorremos à pesquisa bibliográfica e documental como método de procedimento para coleta dos dados e análise do conteúdo dos relatórios apresentados pelos grupos pesquisados. Os resultados revelaram que a pedagogia da alternância promove a articulação com os saberes e o diálogo intercultural entre a comunidade local e a universidade. A curricularização da extensão popular na formação inicial possibilitou a imersão dos educandos na comunidade local e a construção da identidade profissional docente, no contexto local, em áreas de reforma agrária.

Published: December 2022

THE PURPOSE. Consider the problem of using a special ferromagnetic paste, which fills the air gaps in the magnetic circuit of an oil power transformer, in order to reduce its losses, by reducing eddy currents in the magnetic circuit. Conduct experiments to determine the dynamics of change of high-voltage breakdown of transformer oil, after adding ferromagnetic paste to it.METHODS. To solve this problem, several samples of ferromagnetic paste have been developed, differing from each other using different binding material for ferromagnetic powder. The samples were placed in containers for several days filled with transformer oil. With the help of electrical installation AIM-90, measurements of high-voltage breakdown of transformer oil of each sample were carried out. Thanks to this method, it was possible to determine how the ferromagnetic paste affects the insulating properties of the transformer oil. RESULTS. For clarity, the results of all samples were plotted. Based on the graph, it became clear that in some samples of transformer oil a significant amount of mechanical impurities formed from ferromagnetic paste appeared, which extremely negatively affected the insulating properties of the oil. There were also samples in which the properties of the oil practically did not change. CONCLUSION. As conclusions, there was a certain vision of which ferromagnetic paste can be used in the design of an oil power transformer, it was also possible to understand which samples of ferromagnetic pastes extremely negatively affect the insulating properties of the transformer oil.

THE PURPOSE. Consider the combustion process of two coals of different degrees of metamorphism and their mixtures using thermogravimetric analysis based on the change in mass and the rate of change in mass during the heating of fuels. Determine the main characteristics of fuels and the combustion process (temperature of ignition and burnout of the coke residue). Determine the tendency to slagging of coal mixtures. METHODS. When solving the tasks, the thermogravimetric method (TGA). RESULTS. The article provides a brief overview of the combustion of non-design fuels at thermal power plants. The results of technical and elemental analysis of Chernogorsk bituminous coal and Balakhta brown coal are presented. A technique for determining the ignition temperature and burnout of the coke residue is described. The thermograms of the combustion process of two coals of different degrees of metamorphism and their mixtures are presented. The main characteristics of their combustion have been determined. A qualitative analysis of the surface of fuel particles for the presence of pores and cracks is shown. The calculation of the tendency to slagging of coal mixtures has been carried out. CONCLUSION. Thermogravimetric analysis showed an earlier ignition of the Balakhta brown coal in comparison with the Montenegrin bituminous coal. With an increase in the proportion of Balakhta coal in the coal mixture, the profile of the combustion curves shifts to the region of lower temperatures. The addition of 25% Balakhta coal reduces the ignition temperature of Chernogorsk coal by 16%, with an increase in the proportion of Balakhta coal in the mixture, the ignition temperature does not change. Balakhta coal has a high tendency to slagging furnace walls, in contrast to Chernogorsk coal, therefore, an increase in its mass fraction in the coal mixture increases the tendency to slagging furnace screens.

Published: December 2022

Based on the statistical analysis of publications and patents located in the RSCI database for the keywords «exoskeleton», «anthropomorphic robot», «bionic prosthesis», interest in the research topic has been established, expressed in a significant increase in publications in recent years. It was revealed that most of the models use absolutely solid links in the form of rods.GOAL. Identification and study of problems arising in the modeling of anthropomorphic robotic systems. METHODS. Methods of mathematical modeling, analysis, comparison with a biological prototype, robotics, theoretical mechanics, electromechanics were used. RESULTS. The problem of accuracy of modeling by rod robotic systems with absolutely rigid links, a link of the human musculoskeletal system, is considered. The relative error of the accuracy of approximation by rods of a human limb is calculated, a conclusion is made about a significant error in the modeling of links. The problem of evaluating the influence of a rotating rotor of an electric motor on a mechanism model is considered. Next, the model is considered taking into account the rotating rotor and gearbox. It has been established that when modeling anthropomorphic mechanisms with rods, the problem arises of the need to take into account the dynamics of drives. An electromechanical model of a link with a DC motor is proposed. A significant increase in energy costs during the movement of the link has been established, in comparison with the model of an ideal hinge, in which the required control moment is created, which is a problem. A partial solution of the identified problems is proposed using the model of a variable length link containing three sections. CONCLUSION. The study made it possible to identify problems that arise when modeling the human musculoskeletal system with rod robotic electromechanical systems with absolutely solid links.
Corrective Function Method for the Fractal Analysis
Authors: Lazorenko O.V. , Onishchenko A.A. , Chernogor L.F.
Published: December 2022

One of the main numerical characteristics used in numerous methods of fractal analysis is the corresponding fractal dimensions. The accuracy of estimating these dimensions in the vast majority of cases is quite small, which cannot satisfy, first of all, researchers-practitioners. The method of the corrective function is put forward, which makes it possible to compensate for the ever-existing nonlinearity of the dependence between the true value of the fractal dimension and its estimation, performed using the selected method of monofractal analysis of signals and processes for a known number of samples of the discrete data vector of the investigated signal. The main idea of the method is to build and apply a special correction function using a set of model fractal signals with previously known values of the fractal dimension. The mathematical bases of the new method are outlined. Features of the practical application of the corrective function method are considered on the example of the evaluation of regularization, boxing, variation and Hurst fractal dimensions. For them, the minimum values of the number of samples of the discrete data vector of the investigated signal, at which these dimensions can still be estimated, are defined. Using a set of model monofractal and multifractal signals on the example of the dynamical fractal analysis method, the effectiveness of the created method of the corrective function is shown. It is proven that due to the application of the correction function method, the maximum deviation of the estimated fractal dimension from the true known value for the specified dimensions is reduced from 25 – 55% to 5 – 7%.
APPLICATION OF QUEUING THEORY TO THE ESTIMATION OF THE FEATURE SPACE FOR RADAR SOURCES IN MACHINE LEARNING
Authors:   Peter the Great St. Petersburg Polytechnic University, 195251, Politehnicheskaja street 29 St. Petersburg, Russia, Kvasnov A.V.
Published: December 2022

The estimation of the feature space in analysis of radar signals (airplanes, ships, navigation stations, etc.), is an important element of machine learning. From the point of view of queuing theory, a mathematical model of a complex detected signal can be represented as the ordinary flow of events described by a Poisson distribution for randomly varying parameters of a signal. The paper demonstrates the orthogonality of the characteristic space of radar sources based on the entropy estimation. We show that the information measure of the discrepancy (Kullback-Leibler divergence) between intra-pulse modulation signals and frequency-modulated signals decreases with increasing pulse duration. Thus, in the recognition of radar sources using methods of machine learning, it is possible to limit ourselves to features without algorithms for processing intra-pulse modulation. Key words: radar source, queuing theory, Kullback-Leibler divergence, machine learning.

The results of the development of an information system providing the integration of satellite microwave radiometric sensing data of geostationary observations in the visible and IR range are described. This integration is designed to ensure the restoration of atmospheric temperature and humidity profiles in the conditions of emergency atmospheric situations caused by mesoscale convective complexes (MCC). The methodological feature of the developed approach is to minimize the probability of stopping the data analysis system when access to individual sources of a priori information is terminated. This technique is based on the use of an automatic system of adaptation to changes in access conditions and the application of the results of model forecasts of the development of atmospheric processes.

It is aimed in this study to analyze the effects of the Montessori education method on children with Down syndrome and autism having special training who have received and not received Montessori education through the Eurofit test batteries selected for motor skills and physical fitness. A total of 20 male children with Down syndrome and autism in the age range of 12 to 16 and receiving and not receiving Montessori education at two different special education and rehabilitation centers in Kayseri were included in the study. The treatment group included a total of 10 children, 5 with Down syndrome and 5 with autism, and the control group of 10 children, 5 with Down syndrome and 5 with autism. While the volunteers included in the treatment group received Montessori education, those included in the control group received a traditional education. In the study, the volunteers performed the selected Eurofit tests including flamingo balance, plate tapping, sit and reach, handgrip and standing long jump tests. When the results of the Eurofit test batteries of the treatment and control groups were examined, plate tapping and standing long jump test results were found significant in the comparison of the pretest and posttest of the treatment group (p < 0.05). In the pretest and posttest comparison of the control group students, a significant difference was determined in the sit and reach test (p < 0.05). In the posttest comparison of the control and treatment groups, a statistically significant difference was determined between the pretest and posttest measurements of the plate tapping and between the pretest and posttest measurements of the standing long jump (p<0.05). In the pretest comparison of the control and treatment groups, no statistically significant difference was found between the pretest and posttest of flamingo balance, pretest and posttest of plate tapping, pretest and posttest of sit and reach, pretest and posttest of standing long jump and pretest and posttest of handgrip measurements of the control and treatment groups (p>0.05). Consequently, the use of Montessori education materials supports the big and small muscle groups of children with disabilities since most of them learn about an object through touch. In our study, when some activity and motor skills of the children with down syndrome and autism in the special rehabilitation school that uses the Montessori education method were analyzed, it was observed that there was an improvement in their physical activities and some motor skills according to the results of plate tapping, standing long jump and sit and reach tests. It is recommended that education programs can be prepared by using Montessori Approach as part of the education programs applied in preschool education institutions and that they can be used more widely together with traditional education programs.

El endofitismo de hongos en plantas tiene efectos benéficos y depende de varios factores. En este estudio se evaluó el endofitismo individual y el consorcio de cinco especies —Trichoderma spirale, T. longibrachiatum, T. parareesei, T. andinense y T. hamatum— en raíz y bráctea de banano Williams y Francés in vitro. La mortalidad, la longitud y el diámetro de raíz de plantas ex vitro fueron evaluados. Se observaron diferencias significativas de endofitismo en raíz (X21.00= 31.13, P<0.05); T. longibrachiatum y T. hamatum tuvieron 48 por ciento de endofitismo en la variedad Williams, y T. spirale, 58 por ciento en la variedad Francés. El tratamiento formado por las cinco especies presentó 24 por ciento de endofitismo en raíz de la variedad Williams y 8 por ciento en la variedad Francés. Se observó relación entre endofitismo y crecimiento de diámetro de raíz (R2= 0.771, P<0.05); sin embargo, no se observó relación (R2= 0.298, P<0.05), (R2= 0.089) entre endófitismo de especies de Trichoderma y mortalidad de plantas de banano de ambas variedades.

Vanilla planifolia Jacks. ex Andrews es una orquídea endémica de México que está sujeta a protección especial en la NOM-059-SEMARNAT-2010. El objetivo fue evaluar el efecto de sustratos orgánicos y un biofertilizante en el desarrollo de raíces en esquejes de V. planifolia. El experimento se realizó en un diseño completamente al azar. Los tratamientos fueron: vermicomposta (T1), bocashi (T2), combinación de 50 por ciento bocashi y 50 por ciento suelo agrícola (T3), suelo agrícola con biofertilizante (T4) y suelo agrícola (testigo; T5). Los abonos orgánicos y el biofertilizante favorecieron el porcentaje de enraizamiento de los esquejes en 90 por ciento e influyeron en el periodo de brotación (49 días) respecto al testigo (80% y 71 días). La vermicomposta mostró mayor longitud y diámetro de raíces primarias (15.3 y 0.33 cm) y secundarias (2.9 y 0.168 cm). Los abonos orgánicos como sustratos tuvieron un efecto positivo en la formación de raíces y brotes en esquejes de vainilla.

Los sistemas de información geográfica (SIG) y de percepción remota (PR) ayudan en el manejo y análisis de la información en los distritos de riego (DR). Por tal motivo, el objetivo del presente estudio fue generar un SIG y dar seguimiento al avance de riego superficial de un módulo del distrito de riego 017 Región Lagunera, México. Para esto, se integró un SIG a partir de topografía de precisión, y se utilizaron diez imágenes del satélite Landsat 8. Los resultados indican que la red principal tiene 19.5 por ciento de menor longitud en el canal lateral derecho (CLD) 57+839, de acuerdo con las cifras oficiales. Los principales cultivos sembrados fueron algodón (35.7%) y nogal (34.3%); asimismo, se identificó 24.2 por ciento de superficie excedente. Los SIG y PR facilitan el seguimiento del avance de riego en el módulo, lo cual contribuye a realizar un uso eficiente del agua.

Authors: Games Donard
Published: December 2022

Southeast Asia may be considered forgotten in the world of football as no country in this region can compete with any football countries in Europe or the neighboring countries such as South Korea, Japan, and Australia. Countries such as Indonesia, Malaysia, Vietnam, and Thailand have never competed in the World Cup, but one should not ever doubt their continuing fervor for football. The question arises as to why these countries cannot translate their potential into actual achievement football-wise achievements and in terms of sport-based entrepreneurship. This paper uses the concept of sports entrepreneurship and entrepreneurship as a process to capture the essence of football entrepreneurship from the context of Indonesia, the largest and most populous country in Southeast Asia. The study identifies several ways to encourage creativity and innovation as part of value creation in football entrepreneurship in the country.

Published: December 2022

Background: The health-promoting school (HPS) is a WHO-sponsored framework. This national study aimed to explore the experiences and progress in implementing the HPS programme in Saudi Arabia (SA). Methods: A self-completed postal questionnaire was sent to all 42 school health departments across SA, and the response rate was 100%. Results: Forty respondents (95%) had implemented the HPS programme. Over 400 schools were involved in the HPS programme of which two-thirds were primary schools. The most common activities addressed were health education activities. Less frequently mentioned were healthy school policies, action on the social environment, and developing links with the community. Evaluation was only through internal processes. The main perceived strengths of the HPS were increasing the awareness of students and school staff and improving the school’s physical environment. The main weakness was the lack of legislation and financial support. For further development, the respondents reported the need for financial and human support. Conclusion: This study highlights the growth of the schools participating in the HPS programme. Further research is needed to develop and fully evaluate the effectiveness of the HPS framework in SA.
