Phenomenological Aspects of the Study of the Concept of “Cultural Status”
Authors:   Volgograd State University, Khrapova Viktoriya , Komova Valentina ,   Volgograd State University
Published: February 2023

The subject of this research is the concept of "cultural status", the actualization of which in scientific and philosophical discourse indicates the increasing role of culture in the modern world and the need to comprehend the position of the subject of cultural creativity, its importance in the organization of socio–cultural space. The authors use the phenomenological approach as the most heuristic in the conditions of social transformation, allowing to consider the object in a naturally formed context, to apply methods and techniques corresponding to research intentions. The work is based on the comparison of the concept of "cultural status" with the concept of "social status", widely used in sociological science. The conceptual provisions of P. Bourdieu's sociological theory, as well as the guiding theses of the activity approach in the study of culture, allowed the authors to conclude that social status reflects a person's place in the social hierarchy, position in the space of social relations, and cultural includes a much wider range of parameters rooted in people's daily lives, diverse experience of connections and relationships, gaining value value; cultural status characterizes the position of its bearer in the space-time continuum and the context of values, norms, relationships, the ontological position of the subject of cultural creativity, determined by the measure of activity to create a cultural order, which correlates with the social and carries a life-creating potential. The authors identify the components that influence the formation of cultural status: spatial and temporal parameters, the specifics of values, the role of the subject. The emphasis on the active, active beginning of the subject of cultural creativity, whose status position presupposes choice, decision and responsibility, allows for a productive search for mechanisms to optimize the life of a person and society in a risky world. The novelty of the study consists in clarifying the semantic the structure of the concept of "cultural status," the study of discursive fields that influence its formation in the conditions of modern social dynamics. The phenomenological approach allows us to master the discursive space in movement from life to rational, capable of becoming a reliable tool in the formation of sociocultural space as an integrity necessary for the harmonious existence of man and society.
The Social Conditions of Preservation of Traditional Rituals and Antiques in Rural Communities of North Udmurtia
Authors:   Udmurt State University, Vlasova Tatiana
Published: February 2023

This article deals with the perception of folk traditions among modern rural residents. In the last few years, the interest in ethnic culture is represented by changes in attitude towards the material culture and rituals, which are perceived as the manifestation of tradition. Following the change in modern country lifestyle, the practices which regulate the everyday routine change as well. The main research goal was to specify how rural residents incorporate things and rituals they see as traditional into their modern way of life. The empiric base of the research consists of survey data (n = 453) and semi-structured interviews (n = 36) from Debyosy, Igra and Kez districts of the Udmurt Republic. Results showed that traditional goods are preserved as the part of family memorial practices, and they are being recognized as things connected to the Udmurt culture in families with Udmurt ethnic identity. The drive to preserve the rituals develops in villages where the ethnic celebrations ensure the legacy transfer between generations. The pivotal role in preservation of rituals belongs to the replication of traditional rural activities, and their disappearance leads to abandonment of rituals. It also leads to the abandonment of ritualistic actions in daily life and communication. The activities of cultural centers where the folk rites become the part of scene performance help to inform about the ethnic traditions in their "invented" form. Such actions aren't fictional in their nature because they serve as a basis for familial, friendly, and neighborly communication. Traditional rituals and household things in their modernized form then become the foundation of ethnic identity.

Published: February 2023

A popularização dos jogos online no contexto do tempo presente trouxe diferentes formas de se jogar e se conectar, evidenciando-se o Play-to-earn. Nesta modalidade destaca-se o game ‘Axie Infinity’ como uma forma de performance esportiva virtual que gera a possibilidade de captação de recursos financeiros (dinheiro virtual) e, consequentemente permite trocá-lo por qualquer moeda correte em diferentes países. Nessa forma híbrida de jogo/trabalho, milhões de jogadores adentraram esse mundo e buscam ganhos financeiros através dessa prática. O estudo busca identificar o perfil dos usuários de Axie Infinity no contexto brasileiro. O estudo avaliou um dos times com maior prestígio no Brasil, e identificou qual a relação entre tempo livre, tempo de jogo e o uso do tempo com as atividades da vida diária tais como: sono, afazeres domésticos, tempo para a família e amigos, estudos ou trabalho. Foi realizada uma pesquisa de caráter exploratório e descritivo com uma amostra aleatória simples (n=33). Observou-se que o perfil de jogadores do Axie Infinity no Brasil é correspondente a jogadores abaixo dos 18 anos, sendo crianças em fase escolar. Essa relação do jogar para ganhar impõe metas e objetivos diários, dispendendo boa parte do tempo que poderia ser utilizado para outras necessidades em prol do retorno financeiro desejado. Questiona-se uma possível dependência do jogo no perfil de jogadores encontrados na pesquisa, que pode gerar impactos negativos na saúde, nas relações sociais, no desempenho escolar, além de mudanças de comportamento. Embora a pesquisa não tenha o objetivo de investigar os impactos negativos do jogo Axie Infinity em seus usuários, recomenda-se futuras pesquisas para compreender os efeitos e consequências deste jogo.

Standing out in context: Prominence in the production and perception of public speech
Authors: Im Suyeon , Cole Jennifer , Baumann Stefan
Published: February 2023

This study investigates the relationship between signal-based factors and discourse context in the production and perception of prominence, extending prior work on prominence in American English by examining speech from complete TED Talks as examples of a public speech style. First, we conduct a production study. The TED Talk speech samples are analyzed for relationships between (1) phonological pitch accent, (2) acoustic prosodic features, and (3) information structure, modeled here in terms of referential and lexical givenness as well as focus related to semantic alternatives. Second, we conduct a perception study. Word-level prominence ratings obtained from untrained listeners are analyzed for the effects of these (1) phonological, (2) acoustic, and (3) information structural factors. The aim of this study is to evaluate the interaction of the three kinds of factors on prominence ratings with speech that is fully contextualized, allowing for information about the speaker, the situational context, and the discourse context to interact with and possibly mediate signal-based cues to prominence. Results from the production analysis show a weak probabilistic relation between pitch accent assignment and information structure for these TED Talk speakers, but only in the presence versus absence of pitch accent with differences between lexical and referential information status. No systematic relationship is found between a word’s phonological pitch accent type and information structure category, though we do find some evidence of the expected gradient variation in the acoustic expression of prominence: Words that are more informative tend to have higher pitch and a wider pitch range. Despite the weak association between signal-based prominence and information structure in production, listeners perceive and rate prominence in a manner that is, to varying degrees, in accordance with the Accentual Prominence and Givenness hierarchies. In sum, the findings contribute new evidence of the mediating effects of contextual factors relating to the phonological status of pitch accents, information structure, and speech style on the interpretation of acoustic cues to prominence.

Published: February 2023

Hydro-gas regularities of liquid combined blowing by gas were studied using cold modeling method at Archimedes criterion for lateral Arl = 12÷120 and bottom blowing Arb = 5÷60 simulating Pobeda bubbling unit. The blowing was performed simultaneously by bottom lance vertically fixed in centre of reactor and by the lateral lance which was attached at an angle 5° to the horizontal axis. The quantitative estimation of instantaneous and average circulation velocities (Vav) of liquid flow elements in different bath areas, depending on the location of blowing zone and Archimedes criterion, was performed. The liquid motion trajectory was determined. A vortex zone was revealed near the liquid surface and the reactor shell, where instantaneous velocity of the liquid flow elements changes from 69.9 to 181.1 mm/s and Vav = 123.8 mm/s. The circulation flows fade in the bulk of liquid and Vav decreases from 123.8 to 47.0 and 54.1 mm/s. It was shown that, in general, circulation velocity depends on the blowing intensity and appears to be higher for the zone of overlapping of lateral and bottom streams. The dynamic blowing conditions, which ensure the direct contact of lateral and bottom jets leading to their interflow and increased spatter formation, were identified. The characteristics of 3 types of surface oscillations for interface phases “pure liquid- gas-liquid layer”, as well as the estimation of the lateral and bottom blowing impact on the type of oscillation were provided. It has been noted that the introduction of the bottom blowing (Arb = 5) causes the wave-like motion of liquid (the 2nd type) along with the transverse oscillations of the 1st type, and at higher values of Arb = 25 the angular oscillations of the 3rd type develop. It has been shown that the presence of a lateral jet at the combined blowing decreases angles of bath swinging to 8–12° to horizontal axis. For the estimation of oscillation intensity, Δhl = (hl )max – (hl )min value, which means the difference between maximum (hl )max and minimum (hl )min height of liquid for the full-wave oscillations (τ), was introduced. The height of liquid (hl ) was plotted as a function of τ, Arl , Arb, Δhl was determined on the basis of obtained graph values, which varied upon modeling over the range of 7.7–69.5 mm. The relation between the liquid circulation velocity and the oscillation value (Δhl ) was established for different bath zones and dynamic conditions of the blowing. The impact of all oscillations types on potential erosive lining wear of Pobeda bubbling unit and the completeness of adoption of charging material nearby the bath surface was investigated.

Published: February 2023

The data on the complex processing of iron ore from one of the deposits of the Republic of Kazakhstan, which involves several operations of wet magnetic separation with re-grinding of raw products and their subsequent refining to produce a conditioned iron concentrate with 65–66 % iron containing 79–80 % Fe and 2.2–2.5 % Si, are presented. It was found that during the magnetic enrichment of the ore under study, the copper minerals concentrate in the magnetic separation tailings and the copper content in them increases from 0.093 to 0.2 %. A scheme and reagent system have been developed for the recovery of conditioned copper concentrate from magnetically enriched tailings. To obtain copper concentrate, magnetic separation tailings are subjected to regrinding in a lime medium to a fineness of 75 % of the –0.071 mm grade. After two operations of the main copper flotation with the use of water glass, butyl xanthate and frother MIBK, waste tailings are obtained. The froth product of the first basal flotation is cleaned twice. The result is a copper concentrate containing 15.2 % copper, 26.5 % iron, 17.5 % sulfur, 3.47 % silicon, 1.4 % aluminum and 8.5 % zinc, which corresponds to the KM-7 grade according to GOST R 52998-2008. Waste tailings contain: copper 0.08 %, iron 20.1 %, sulfur 0.25 %, silicon 16.2 %, aluminum 6.4 % and zinc 0.045 %. The influence of xanthates with different length and structure of hydrocarbon radical as well as hostaflots and amyl aeroflots on the process of copper flotation is studied. The high efficiency of butyl xanthate in the flotation of copper minerals has been confirmed.

The road network in Tocantins is of fundamental importance for the development of productive and expansion activities in the state. The BR-242 / TO highway that will be the object of this research is located in the southeast of the State of Tocantins, and will interconnect and serve three states of the Brazilian federation, Bahia, Tocantins and Mato Grosso, with an extension of 262 km, passing through the municipalities from Taguatinga, Paranã and Peixe. The objective of this study is to describe and evaluate the environmental compensation actions of the impacts on fauna, flora and water resources, originated from the implementation of the highway (BR-242/TO). The results of the Vegetation Suppression and Flora Rescue report were used; the results of the Wildlife Removal and Rescue report; and the report of the Water Bodies Monitoring Program produced between the years 2016 and 2019 within the scope of the execution of environmental management services for the construction works of the BR-242 / TO highway. The environmental management implemented in the construction of the highway has brought positive results with its programs for rescuing fauna, flora, collecting seeds and collecting water samples from rivers to analyze water quality. The mitigation and compensation measures implemented before, during and after the work, can drastically reduce the environmental impacts to the environment, resulting in environmental sustainability to the work, gains for the environment and for the communities surrounding the built enterprise.
Geoheritage of the Brazilian Pampa where actions of Geoconserve, Geopreserve and Geoprotecting are the Challenges of the 21st Century
Authors:   Serviço Geológico do Brasil - Companhia de Pesquisa e Recursos Minerais, PEIXOTO Carlos Augusto Brasil
Published: February 2023

The biome of the “Pampa” in Brazil is a restricted area located in the state of Rio Grande do Sul, that extends for 153.254 Km2 and constitutes 1.79% of the national territory. Unfortunately, it has been severely impacted by agribusiness activities. The present study will show a strategic importance for the environmental preservation of the “Pampa” geoheritage. The goals are to reset the borders of the “Pampa”, to identify geosites of scientific value, and to evaluate the risks of environmental degradation with the aim to propose geoconservation actions. The material for this study came from Brazilian Institute of Geography and Statistics, Geological Survey of Brazil and edited using the geographic information systems program ArcGIS - ESRI®. The evaluation methodology used consists of the systematic registration of geological sites using different scales and values, and by mathematical criteria showing the relevant value and the degrees of environment degradation risks. The results present three maps showing the borders (limits) of the “Pampa” biome, geodiversity, and geosites and in as well as frames and charts, which contain the scientific value and the degree of environmental degradation risk of the six geosites. This information will be useful in proposing a course of action for geoconservation such as: the creation of conservation units, geoparks and the updating of environment legislation. The proposed actions are fundamental for spatial planning, based on the best practices of sustainable development, as geoconservation, geopreservation and geoprotection still remain the major challenges of the 21st century.
Aromatherapy in conjunction with physical/occupational therapy in an acute care setting: Early results
Authors: A Elizabeth Koyle , Nicole Hofmeister , Rebecca Reding
Published: February 2023

Pain and nausea are common complaints by patients in acute care settings and these symptoms can prevent participation in their physical or occupational therapy sessions. Because mobilization during acute care hospitalization is important for reducing the length of stay, postoperative complications, risk for deep vein thrombosis, pneumonia, and pressure ulcers, implementing non-pharmacological solutions to engage patients in mobilization is worth investigating. It is hypothesized that the use of inhaled essential oils may improve patients’ perception of pain and their coping with nausea, enabling a patient to have active participation in physical or occupational therapy. This participation can minimize hospitalization-related risks as well as potentially reduce the length of stay in the hospital. This IRB-approved study is an early feasibility, single-site, randomized, placebo-controlled clinical trial utilizing three essential oils: lavender, mandarin, and peppermint. These oils are administered via an inhalation patch affixed to the chest region of the subject’s gown. Perceived pain or nausea levels are assessed before and after the use of aromatherapy during which the subject participates in their planned physical or occupational therapy session. While it is too early to determine the effects of aromatherapy, preliminary results suggest the use of lavender oil may have a positive effect on pain.

Published: February 2023

Ovarian Cancer (OC) is the leading cause of gynecologic cancer-related deaths worldwide. The leading risk factors for OC-related death are OC recurrence and the development of chemotherapy resistance. Investigation into molecular differences that distinguish primary from recurrent disease and the role of the tumor microenvironment (TME) in OC progression may help identify therapeutic targets. Gene expression microarray data comparisons between 21 primary and 21 recurrent OC specimens (16 matched pairs) showed significantly increased expression of Matrix Metallopeptidase 1 (MMP1) in the recurrent specimens (p = 0.03). We, therefore, investigated MMP1 expression regulation and how endogenous and exogenous MMP1 expression influences OC cell proliferation, migration/invasion and chemosensitivity. Both endogenous MMP1 knockdown and low levels of exogenous MMP1 increased cell proliferation of the OC cell line, CAOV2 (p < 0.01 and p < 0.001, respectively). Furthermore, CAOV2 cells cultured with low exogenous MMP1 exhibited increased invasion (p = 0.04 and p = 0.002, respectively, for two shRNA-conditioned mediums, shMMP1-1 or shMMP1-2) and faster migration by wound healing assay relative to controls without MMP1 knockdown. CAOV2 MMP1 knockdown cells were also more resistant than controls to carboplatin (p = 0.04) and paclitaxel (p = 0.017). To explore the functions of cancer environmental MMP1 in different cancer cells, 3 OC cell lines (CAOV2, HEYA8 and SKOV3) were tested for their proliferation when cultured under a low MMP1 conditioned medium. Interestingly, while the proliferation was increased in CAOV2 and HEYA8 cells, it was reduced when SKOV3 OC cells were cultured with low exogenous MMP1 (CAOV2: * p = 0.01, HEYA8: **** p = 0.0004, SKOV3: ** p = 0.002). These results likely reflect inherent MMP1 expression variability in OC tissues and cell lines that is at least partly dependent on other endogenous parameters of the TME, including pH, metabolic state, and oxygenation, all of which were found to alter levels of endogenous MMP1. Given the ability of MMP1 to promote oncogenic or tumor-suppressive behaviors, further study will be necessary to better understand how MMP1 contributes to promoting or restraining tumor progression in an individualized manner.
BCA analysis of hydrolyzable proteins in pollen using the Pierce BCA assay kit v1
Authors: J. Carroll Mark
Published: February 2023

This protocol quantifies total protein contents of small amounts of pollen (10 mg) using the bicinchoninic acid (BCA) assay of the Pierce BCA protein assay kit (Thermo Scientific product number 23225). This protocol adapts the kit protocol for analysis of anther pollen, corbicular pollen, and stored pollen from bee colonies. Pollen samples are subjected to acid hydrolysis to digest refractory proteins and to degrade sugars and other pollen substances that interfere with total protein assays. The acid hydrolysis releases substantially more protein from pollens than occurs with soluble proteins but may result in some protein losses due to the harsh acidic conditions. Similar BCA analysis methods without hydrolysis may be used to quantify soluble proteins (proteins obtained without acid hydrolysis or other digest methods) which may exclude insoluble pollen proteins from full quantification. The total protein contents obtained using BCA analysis of acid hydrosylates represents the maximum protein available to consumers and likely includes some refractory proteins that may not be digested by the consumer. The assay is modified from the original standard protocol to work for pollen analysis: Document Connect (thermofisher.com). Please note that our steps differ from the commercial source protocol.

Quantification of pollen cysteine contents by PITC derivatization v1
Authors: J. Carroll Mark
Published: February 2023

This protocol quantifies cysteine residues from small amounts of pollen (10 mg) after phenylisothiocyanate (PITC) derivatization (adapted from Manneberg et al 1995). Quantification of cysteine by other methods is difficult because of its instability during amino acid analysis. Samples of anther pollen, corbicular pollen, or stored pollen from bee colonies are completely digested in strong acid. Cysteine residues are completely oxidized to cysteic acid then derivatized with PITC before HPLC UV VIS analysis. Manneberg, M., Lahm, H., & Fountoulakis, M. (1995).

The ever-increasing temperature of current climate has brought the attention on reducing the incoming solar heat energy into buildings. The efforts on reducing the dependency on air-conditioning for indoor cooling has led to the implementation of passive cooling strategies in buildings. This paper investigates the implementation of reflective technologies in the form of reflective insulation and radiant barrier systems in a gable roof assembly. The thermal performance of reflective insulation and radiant barrier systems was investigated by using Computational Fluid Dynamics (CFD) simulation. The thermal performance of the reflective technologies was presented in terms of thermal resistivity, RSI value. The study was conducted for several roof configurations where the thickness of reflective air space, roof pitch and the roof material were varied. The results obtained from the CFD simulation was validated against empirical measurements to ensure the simulation gives high accuracy prediction. From the parametric analysis, it was found that thicker reflective air space would provide better air ventilation in the air space area which led to higher thermal resistivity. Besides that, steeper roof pitch would enhance the buoyancy effect and increases the heat exhaustion through the ridge which also results in higher thermal resistivity. In terms of roof tiles material, only small difference was observed in terms of thermal resistivity when switching the roof tiles material between clay tiles and concrete tiles. This research was able to demonstrate the use of CFD simulation in investigating thermal insulation technologies in buildings and this method should be explored further in the future.

In this article, field pilot study was undertaken to examine the transport mechanism for total petroleum hydrocarbon remediation in varying concentration using pseudo first order, pseudo second order and intra particle diffusion kinetic models in land farming treatment. Soil samples were artificially contaminated in varying concentration of 1,000 mg/kg (low), 3,000 mg/kg (medium) and 5,000 mg/kg (high) and treated using organic and inorganic fertilizers for a period of 150days which is the duration for effective remediation treatment. The results from the treated samples were subjected to kinetics studies while coefficient of determination (R2) was applied on the residual total petroleum hydrocarbon (TPH) after 150 days of treatment, pseudo first order had R2 values of 0.7898 (low), 0.6776 (medium) and 0.6131 (high). Pseudo second order had R2 values of 0.9737 (low), 0.9467 (medium), 0.7863 (high) while intra particle diffusion had R2 values of 0.9940 (low), 0.9821 (medium) and 0.9489 (high) respectively. The results indicate that intra particle diffusion model best described the kinetics mechanism of TPH remediation using land farming treatment; but when the alteration in the error structure associated with transforming a nonlinear kinetic equation into linear equation is minimized using nonlinear regression optimization procedure, pseudo first order emerged as the best kinetic model having the least sum of errors as 0.000270 (low), 0.000185 (medium) and 0.000278 (high).

RESUMENEl presente trabajo tiene dos objetivos, a) examinar las concepciones de los docentes de centros rurales o en contextos rurales sobre las posibilidades del entorno cercano como espacio de aprendizaje educativo y b) comprobar el tipo de recursos que suelen utilizar en sus clases que pueden vincularse o no con las técnicas de la Historia Rural y la Place-Based Education. Se ha utilizado un cuestionario de elaboración propia que mide el uso de recursos educativos por parte del profesorado y las concepciones de los docentes con respecto a la enseñanza de las Ciencias Sociales, las posibilidades didácticas del paisaje, del medio rural y de la toponimia en el aprendizaje del alumnado, y se ha aplicado a una muestra de 29 docentes de Educación Primaria y Secundaria en centros educativos rurales del Principado de Asturias. Para conocer la fiabilidad se ha aplicado el estadístico Alfa de Cronbach. Los resultados obtenidos al realizar la correlación de Spearman, la t de Student y la d de Cohen evidencian que el profesorado tiene una concepción muy positiva del medio rural como espacio de aprendizaje, si bien manifiesta dificultades a la hora de utilizar todos los potenciales recursos educativos para la enseñanza de ese entorno.Palabras Clave: Educación Rural, Ciencias Sociales, Historia Rural, Recursos educativos, Place-Based Education.ABSTRACTThis paper has two objectives: a) to examine the conceptions of teachers in rural centers or in rural settings about the possibilities of immediate environment as an area of educational learning b) check the type of resources they typically use in their classrooms that can be linked or not with the techniques of Rural History and Place-Based Education. It has been used a specifically designed questionnaire that measures the use of educational resources by teachers and conceptions of teachers regarding the teaching of Social Sciences, the educational possibilities of the landscape, rural and place names in the student learning. The questionnaire has been applied to a sample of 29 teachers of primary and secondary education in rural schools of the Principality of Asturias. For reliability, has been applied Cronbach alpha statistic. The results obtained by performing the correlation of Spearman, Student’s t test and Cohen’s d show that teachers have a very positive view of rural areas as a learning space, while they evince difficulties to use all the potential educational resources for teaching that environment.Keywords: Rural Education, Social Sciences, Rural History, Educational Resources, Place-Based Education.

Exercise Prescription in Patient with Different Complications of Leukemia
Authors: Chen Yanzhong
Published: February 2023

Common treatment of leukemia will have side effects on nerve function, affecting the patient's physical function, which makes patients often accompanied by infection, bone and joint pain, fatigue and other symptoms. Exercise can improve the level of body function, enable patients to tolerate stronger chemotherapy during treatment, help improve the survival rate and recovery chances of patients, and has been used as an effective means to promote recovery. Recommendations for leukemia and exercise have been primarily based on the results of existing relevant studies. To provide more targeted recommendations for the leukemia, we gathered evidence for the efficacy of exercise for leukemia, and concluded with recommendations for exercise prescription for the rehabilitation of patients with leukemia during and after chemotherapy. We used "leukemia", "exercise" as keywords, retrieving related literatures in CNKI, VIP, Wanfang, PubMed and Web of Science databases by December 20, 2021. Based on the analysis of research methods and outcome indicators, we extracted the exercise prescription for leukemia patients. Relative safe and effective exercise prescriptions were obtained for leukemia patients. For example, for patients with cardiopulmonary injury, a 6-minute walk can be more safely used for testing, aerobic exercise can be performed for 3-5 days/week, and each exercise time can be gradually increased from 10min to more than 30min. Also, it may be more effective to replace HHR (40%~59%) with RPE (12~13) for their intensity monitoring. Therapeutic exercise, especially with an element of strengthening combined with aerobic training, is an efficacious treatment for leukemia. Notably, with the development of technology, the ways of exercise available are diversifying, many complementary training methods such as Spotlight program, Team works, are also effective. At the same time, multi-mode, remote and home interventions are becoming more and more popular, providing a new direction for patient prognosis. However, the prescription recommendations are only for practical reference. There are insufficient high quality studies on exercise rehabilitation and prescription for patients with leukemia and various complications, and more research support is needed to develop more accurate exercise prescription.

Autism Spectrum Disorders (ASD) is urodevelopmental disorder characterized by social and communication impairments as
well as a wide range of behavior deficits. For years, motor disturbance reported in ASD has not been treated as a major
core deficit because of the overwhelming problems in sociability and communication. Recent studies, however, reveal that
motor deficits are associated with the core symptoms of ASD. Because limited studies have addressed motor behavior of
children with ASD, especially in China, the purpose of this study is to explore the development of fundamental movement
skills in children with ASD and compare it to that of typically developing (TD) children. A total of 108 children with
ASD aged 5-14 years and 108 age- and gender-matched TD children were evaluated. FMS were assessed with the Movement
Assessment Battery for Children 2nd edition (MABC-2) including manual dexterity, aiming and catching, static and
dynamic balance, and overall motor skills. The results included: (1) The development of FMS of children with ASD
was significantly behind that of the children with TD at the same age. About 80% of children with ASD experienced
motor difficulty or were at risk for motor delay. (2) Children with ASD showed significantly lower standard scores
than typically developing children at the same age on manual dexterity, ball skills, and static and dynamic balance
and overall MABC-2 scores (all p < 0.001), and there was no significant gender difference
(all p > 0.05). Besides the core areas of developmental deficits described in the diagnostic manual
for ASD, clinicians should assess motor deficits when diagnosing and treating children with ASD. Evidence-based interventions
on FMS should be introduced when motor deficits are present.

Since 2017, the Ministry of Education has taken the lead in establishing the 'Starry Star' pilot training camp. As a leading city of school football campaign/activity, Zhengzhou City takes up heavy responsibility of continuously promoting the rapid development of school football in Henan Province. This paper adopts such methodologies such as literature, fieldwork, mathematical statistics and logical analysis to identify the weaknesses in the current phase of construction and to make reasonable recommendations according to policies and the actual situation for pointing out the direction for the future development. In terms of organizational leadership, all relevant policies and documents are well-developed reflecting the high degree of importance attached to each training camp, but very few of them have omissions in the development of the system of admissions and training management regulations. In terms of condition guarantee, three aspects are prominent, including the treatment of coaches (calculation of hours), the size of the training grounds at each training site not meeting the requirements of the camps' participation groups (due to limited size of the campus), and the lack of implementation of supporting funds (in the surrounding counties). In terms of competition and training, all schools lost points to varying degrees in the various detailed assessment indicators of the survey and assessment such as inappropriate teaching attitude of the teaching staff, unsystematic training syllabus, unfinished work arrangements for two tournaments and one practice and insufficient attention to the campers' performance in cultural subjects. In terms of reserve training and training participation rate, nearly 30% of the camps failed to send outstanding athletes to higher level schools; half of the camps failed to ensure over 90% attendance of campers. It is suggested that relevant authorities should in future give standardized and clear policies regarding admissions and other related systems. Further, the authorities should clarify the way of coaches' salary and title appraisal, focus on the implementation of matching funds for training camps, and gradually adjust the correspondence between matching camper groups and camp site conditions. As the main task of the Starry Star training camps, more attention should be placed in future work, improving policies, seriously correcting and dealing with various situations that affect the quality of race training in each camp. The authorities should optimize the way of supplying outstanding athletes, and at the same time strengthen regular inspections and random checks for the attendance, putting equal emphasis on training quality and participation.

Life satisfaction is an overall cognitive evaluation of an individual's living condition for the most of time or over a certain period
of time according to the standard of one’s own choice. It is an important psychological variable in the developmental stage of
children and adolescents. Some studies had shown that life satisfaction was closely related to children's and adolescents' mental
health levels, including their emotional and behavioral conditions. However, the Blue Book for Children: China Children's
Development Report (2020) published by China Children's Center stated that Chinese students did not
fare well in terms of life satisfaction. Previous studies had indicated that physical exercise was an important factor that had a
positive effect on life satisfaction, as well as on self-confidence and resilience. Also, there is a correlation between self-confidence,
resilience, and life satisfaction. Nonetheless, few studies have researched the role of self-confidence and resilience in the impact
of physical exercise on the life satisfaction of primary school students. To explore the mediating role of self-confidence and
resilience between physical exercise and life satisfaction, in order to provide a theoretical basis and practical guidance for how
to effectively promote life satisfaction and psychological well-being of primary school students in the practice of physical exercise.
Group measurements of 1009 students (519 boys and 490 girls; 576 fifth graders and 433 sixth graders) are carried out by
using the Scale of Physical Exercise Level, Children and Adolescent Self-Confidence Scale, Children and Adolescent Life
Satisfaction Scale, and Adolescent Resilience Scale, and Structural Equation Model and Bootstrap are used to
analyze the mediating effect of self-confidence and resilience. The results reveal that there is a positive correlation between
physical exercise and life satisfaction(r=0.218), but the effect on life satisfaction is not significant (P=0.516); the indirect
effect of physical exercise on life satisfaction consists of two paths: physical exercise to self-confidence to life satisfaction
(95% CI: 0.128,0.267); physical exercise to self-confidence to resilience to life satisfaction (95% CI:0.109,0.209). It is concluded
that physical exercise has an indirect but significant effect on primary school students' life satisfaction--the independent
mediating effect of self-confidence and the chain mediation effect of self-confidence and resilience. The study further confirms
that physical exercise can promote students' self-confidence levels and the formation of tenacious psychological quality, thus
improving their life satisfaction levels. Therefore, society, schools and families should pay close attention to the positive effects
of physical exercise on primary school students’ emotional and behavioral conditions.
Research on Evaluation Index System of Sports Events Over Urban Development Based on Symbiosis Theory

Published: February 2023

With the development of economic globalization, sports events have become a strategic tool that is used for enhancing the
competitiveness of the city and achieving the government’s goal. Nowadays, a myriad of cities takes organizing sports events as
the goal of urban development. However, what is the relationship between sporting events and urban development? How to build an
evaluation index system to measure the relationship between urban development and sports events? How are sports events coordinated with urban development? These issues have not yet been thoroughly investigated. This study attempts to analyze the relationship and mechanism between urban development and sports events based on the perspective of Symbiosis Theory. The literature review, expert consultation, empirical analysis, and mathematical statistics were conducted in this study. At the theoretical level, this study uses Symbiosis Theory to analyze the relationship between sports events and urban development. The conclusions are as follows: sports events and urban development are two basic symbiosis units that will form a certain symbiotic paradigm through the symbiotic interface and under the role of symbiotic environment, the symbiosis relationship between urban development and sports events is mutualistic symbiosis. The research constructed the index system for the evaluation of the symbiosis relationship of sports events over urban development. The index system is divided into two subsystems, six primary indicators, and 20 secondary indicators. Among them, the confirmation of index weight of the first-level indicators used the analytic hierarchy process, and the second-level indicators used the principal component analysis. On this basis, through empirical analysis of Nanjing Youth Olympic Games as a case, the results showed the correctness of the evaluation index system, to provide references for cities that later hosted sports events.
