Authors: Yuzko V.
Published: September 2021

Objective was to investigate the level of melatonin in the blood and follicular fluid in women treated with infertility by ART method and evaluate the effectiveness of melatonin in their preparation for programs.Material and methods. 89 women were examined. The first (control) group included 13 healthy women oocyte donors who gave birth to their own healthy children, the second group - 33 women with infertility, who two weeks before and during ovulation stimulation were taken simultaneously at the same time before bedtime 3 mg of the drug "Vita-melatonin" produced by "Kyiv Vitamin Plant", the third group - 43 women with infertility who did not take the drug melatonin during ovulation stimulation. ELISA (Germany) reagent kits were used to determine melatonin levels. Melatonin levels were determined in blood plasma, and follicular fluid obtained during the puncture at 9:00 am.Results. The level of melatonin in the blood of female donor oocytes was 130.85 ± 16.91 pg/ml. This rate in the blood of women who used the drug melatonin before and during ovulation stimulation was significantly higher than in the blood of women who did not take the drug (respectively, 143.06 ± 14.87 pg/ml and 123.40 ± 12.65 pg / ml, p <0.05), and in the follicular fluid there was an inverse relationship: the level of melatonin in women of the first group was 97.15 ± 8.69 pg / ml, the second group - 39.46 ± 4.52 pg/ml, which is significantly less (p <0.05), the third group - 62.34 ± 3.94 pg / ml, which is almost twice more (p <0.05) compared with women who took melatonin, but less (p <0.05) compared with the first group. The frequency of pregnancy on transfer in patients of the first group was 80.0 ± 11.01%, in women of the second group probably less - 60.6 ± 8.25% (p <0.05), but also probably higher compared to women in the third group - 45.0 ± 7.62% (p <0.05). A similar pattern was observed by us on the onset of pregnancy in general: in the first group - 100.0%, in the second - 68.9 ± 8.05% (p <0.05), in the third - 60.5 ± 7.47% (p> 0.05).Conclusions. The low level of melatonin in the follicular fluid obtained by us in women who underwent ovulation stimulation in ART programs in the treatment of infertility requires further scientific interpretation. At the same time, the best results of pregnancy in women in ART programs who took melatonin in preparation are encouraging.

The aim – To carry out a comparative statistical and epidemiological analysis of the incidence of malignant neoplasms (MN) of the abdominal cavity and other localizations in the Bukovyna region and possible determining factors.Material and methods. The study was performed on the basis of RMNE "Chernivtsi Regional Clinical Oncology Center" and the Oncology Clinic of Bukovinian State Medical University and covers observation materials and statistical reports of 21259 cases of MN of various localization. Indicators were calculated using Access and Excel software packages based on the Microsoft Office environment.Results. Among all MN of different localization, neoplasms of abdominal organs make up about a third (32.4%), or 37.1% of those diagnosed with MN for the first time, they are distinguished by a significant proportion of III-IV stages and relatively high mortality. In comparison with neoplasms of other localization, the MN of the abdominal organs is common, exceeding at least twice the number of MN of the skin and breast. High mortality was observed in the esophagus (72.4%), stomach (56.2%), hepatobiliary system, and pancreas (67.5-71.4%).Conclusions. MNs of abdominal organs occupy an important place in the general structure of new growths of various localization. MN data are characterized by high mortality rates and insufficient effectiveness of treatment, which requires additional studies.

Introduction

Cette étude vise à examiner les obstacles qui limite l’accès et le recours des jeunes Noirs aux services en santé mentale en Alberta.

Méthodologie

Pour comprendre l’accès aux soins de santé des jeunes Noirs en Alberta, tant ceux qui sont nés au Canada que ceux qui y ont immigré, nous avons utilisé une méthodologie de recherche action dirigée par les jeunes dans le cadre d’un modèle d’autonomisation des jeunes qui s’inscrit dans la théorie de l’intersectionnalité. Le projet de recherche a été dirigé conjointement par un comité consultatif composé de dix jeunes, qui ont donné des conseils et contribué concrètement à la recherche. Sept membres du comité consultatif ont également recueilli des données, animé conjointement des cafés-causeries, analysé les données et contribué aux activités de diffusion. Nous avons réalisé des entretiens individuels approfondis et organisé quatre groupes de discussion de type café-causerie avec 129 jeunes au total. Au cours des cafés-causeries, les jeunes ont pris l’initiative de cibler leurs sujets de préoccupation et d’expliquer les répercussions de ceux-ci sur leur vie. Grâce à un codage rigoureux et à une analyse thématique des données, à la réflexivité et à la vérification par les membres, nous nous sommes assurés de la fiabilité de nos résultats empiriques.

Résultats

Nos résultats mettent en lumière les principaux obstacles susceptibles de limiter l’accès et le recours des jeunes Noirs aux services en santé mentale, notamment le manque d’inclusion et de sécurité culturelles, le manque de connaissances et d’information sur les services en santé mentale, le coût des services en santé mentale, les obstacles géographiques, la stigmatisation et le jugement, de même que les limites de la résilience.

Conclusion

Les résultats confirment l’existence d’obstacles divers et cumulatifs qui, ensemble, perpétuent un accès et un recours négativement disproportionnés des jeunes Noirs aux services en santé mentale. D’après notre étude, les intervenants responsables des politiques et des pratiques en matière de santé devraient prendre en compte les recommandations suivantes pour éliminer les obstacles : diversifier le personnel des services en santé mentale, augmenter la disponibilité et la qualité des services en santé mentale dans les quartiers où la population noire est prédominante et intégrer des pratiques antiracistes et des compétences interculturelles dans la prestation des services en santé mentale.

Published: September 2021

Introduction: It is common knowledge that individuals with mental illness face many negative consequences of stigmatization. They are also super sensitive to the attitudes of health professionals. This study aims to investigate the stigmatizing attitudes and language usage of mental health professionals and to compare them with non-mental health professionals. Material and Methods: A total of 722 healthcare professionals were asked to complete the sociodemographic characteristics data form, the questionnaire including the list of stigmatizing words for mental illnesses, and the Attitudes Towards Mentally Ills Scale (ATMIS). Results: Research shows that mental health professionals have less stigmatizing attitudes when compared to other healthcare professionals (p = .000). However, it is determined that there is no difference in terms of the number of stigmatizing words used by both groups, and the most frequently used psychiatric diagnostic expressions with stigmatizing purposes are personality disorders. The number of stigmatizing words used by physicians is more than nurses (p = .000). Mental healthcare professionals have more positive attitudes in both short-term and the long term relationship scale scores. Both groups show that the mean score is lower in long-term than in short-term relationships. Conclusion: Working in the mental health field does not lead to a positive change in terms of language use in stigmatizing purposes and reducing stigmatizing attitudes in a long-term relationship with individuals with mental illness. It is recommended to increase the awareness of physicians about the use of stigmatizing language.

Published: September 2021

Katarina Milovuk (Ekaterina Đorđević) was born on August 28, 1844 in Novi Sad of Serbia. She proved to be one of the first women to realize her professional potentials "outside the home hearth" in Serbia, and even more authentically as a true Serbian "Heroine of the Spirit" of the targeted fight for women's rights. With her valuable presentation and views, Katarina Milovuk attracted about 3000 ladies from the most prominent Belgrade families, who accepted the task of taking part in the medical training for girls and women to help Serbian soldiers on the battlefield, and who were more decimated by the typhus epidemic than by lethal bullets of enemies. The main opus (her aim) of her social engagement was the historical struggle for women's rights and activities in the education of women's youth in Serbia. As an active participant in social life in Serbia, she participated in the historical organization of aid for the Serbian army during the wars that Serbia was waging at the time.
Digital device overuse during the COVID-19 pandemic and visual impairment among children: Is there a risk for long-term effects?
Authors: Detanac Dženana
Published: September 2021

Global school closures and home quarantine caused by the COVID-19 pandemic increases digital screen time and the overall time spent on near work while decreasing outdoor time especially among school-going children, which can cause serious factors associated with asthenopia, refractive errors, low visual acuity, and accommodative insufficiency. Professionals believe that ophthalmologists now have an opportunity to draw attention to the problem, raise awareness among parents, children, and teachers, and eventually influence policymakers to develop strategies that will help children and students as well as parents and relevant institutions to deal with this issue even beyond the pandemic. Prompt implementation of adequate public and school policies and eye care services globally, effective planning of public health measures for prevention and treatment of myopia must be part of the crucial measures in the future. The consequences of widespread acceptance of digital devices in all spheres of public life by affecting visual function also affect learning, school performance, development of children, and thus their future.
Top Executives Work-Life Balance, Job Burnout and Turnover Intentions: Moderated-Mediation with Knowledge Sharing Culture
Authors: Haar Jarrod , Daellenbach Urs , O'Kane Conor , Ruckstuhl Katharina , Davenport Sally
Published: September 2021

New Zealand top executives are seldom explored, and this paper examines the role of work-life balance (WLB) on top executives’ turnover intentions, with job burnout mediating this relationship. It is expected that top executives with strong WLB will be aided with stronger wellbeing (lower burnout) and stronger work behaviours (lower turnover). Beyond these relationships, knowledge sharing culture (KSC) is included as a moderator and combined, a moderated mediation model is tested. Using data from 126 New Zealand top executives, we find that WLB negatively related to emotional exhaustion, cynicism, and turnover intentions, with cynicism fully mediating the influence of WLB on turnover intentions. A significant moderated mediation effect is found, which indicates that the indirect effect of WLB on turnover intentions through cynicism did vary, with the indirect effect diminishing as KSC becomes stronger. At levels above 0.2SD of KSC, WLB no longer has a significant effect on turnover. The findings add new insights into understanding turnover intentions in New Zealand, especially around boundary conditions of KSC, and highlight the complexity of executive talent retention.

The article describes the development, fabrication, and test results of a double pancake сoil made using second-generation high-temperature superconductors (HTSC-2G). The HTSC-2G coil is the key element of the cryomagnetic system intended for use as part of an experimental research setup for remotely controlling the expression of neurons by means of constant and low-frequency (up to 100 Hz) magnetic field. This project is a continuation of works [1] carried out on the integrated topic “Electronic Components and Neuromorphic Ccontrol Systems”, which includes, as a constituent part, the development and fabrication of an HTSC-2G cryomagnetic system for studying neuron activity under the effect of external magnetic field. A distinctive feature of the project is the use of a cryomagnetic system with a low energy consumption achieved owing to the use of modern HTSC materials. This will open the possibility to continuously observe the object under study from the start of its exposure to magnetic field to the occurrence of reaction signs. The technology for winding a double pancake HTSC-2G coil is developed and described. For making the coil, an HTSC-2G wire in polyamide varnish insulation was used. The technology of making inner junctions in double pancake HTSC-2G coils with a transition resistance of less than 120 nΩ at 77 K has been developed and successfully tried out. The results from preliminary tests of the HTSC-2G coil in liquid nitrogen are presented.

The scheme of an aircraft’s hybrid propulsion system, which includes an assembly of DC voltage converters (some which are bidirectional), fuel cells, lithium-ion storage batteries, a power flow distribution controller, and an inverter electric motor, is proposed. With such scheme, it is possible to flexibly change the power supplied to the electric motor, to scale the propulsion system for the necessary purposes, and to charge the storage battery in the course of aircraft descending and landing. A method for calculating static and dynamic losses in the boost converter used in the propulsion system is presented. The converter mass is estimated depending on the switching frequency for different types of power switching devices, including the calculation of the mass of capacitive, inductive and switching elements. Calculations have shown that the minimum mass of a pulse power converter operating at a repetition frequency of 100 kHz with a power of 80 kW at an output voltage of 300 V is 8.2 kg. With the repetition frequency increased to 1 MHz, the converter mass increases by almost five times to reach 40 kg.
Modeling the Temperature Mode, Monitoring, and Predicting the Overheating Live Bus Bolted Contact Connections

Published: September 2021

The widely used infrared imaging control of bolted connections in live rectangular buses is performed without direct access to the object being diagnosed. This gives only an approximate idea of the contact state, whereas the contact layer condition remains poorly known. The high thermal conductivity of the live bus material makes the thermal field pattern near the contact connection rather soft, which significantly adds complexity to the diagnostics. Therefore, it is important to develop diagnostics of contact connections by dynamic methods based on analyzing the thermal effect of rectangular test or quasi-rectangular operational current pulses in the busbars of electrical installations. By analyzing the temperature field dynamics in the flat contact zone it becomes possible to establish a functional relationship between the contact zone temperature and the bus free surface temperature, and also the relationship between the temperature recorded on the bus surface and the transition resistance, which is the contact quality characteristic. It has been shown, by simulating the contact surface temperature control in the dynamic monitoring mode, that it is possible to determine the rectangular bus bolted connection overheating protection response time. It is proposed to use the obtained dependence as a conversion function for an intelligent electrical contact temperature sensor.

In the channels of mechanical-draft cooling tower sprinklers, a saturated air flow section may appear under certain initial conditions, the mass transfer intensity in which is limited by the steam content in the saturated air. For correctly calculating the heat and mass transfer processes in the cooling tower channel, it is necessary to have a method for determining the unsaturated air flow section length. Publications devoted to studying water cooling processes in the channels of mechanical-draft cooling tower sprinklers do not contain an assessment of the unsaturated air flow section length. A method for determining the unsaturated humid air flow section length in the mechanical-draft cooling tower sprinkler channels is proposed, which is based on the well-known criterion equations for calculating the heat transfer and mass transfer coefficients. The effect the initial air parameters have on the unsaturated air section length is studied, and graphic dependences of the unsaturated air section length are drawn up for each of the analyzed parameters. It is shown that the unsaturated humid air flow section length increases with increasing the initial air temperature. It is also found that the unsaturated air flow section length decreases with a growth in the relative air humidity. An increase in the air flow rate with a constant water flow rate leads to an increase in the unsaturated air flow section length. For the considered sprinkler channel, the saturated air region exists at an air temperature of 15°C and below, and for air temperatures above 25°C there is no saturated air flow section. It is shown that the conclusions drawn about the effect the initial air parameters have on the relative change in the unsaturated air flow section length are valid for channels of various shapes and geometric sizes. The proposed methodology and the results obtained can be used in designing mechanical-draft cooling towers and estimating their efficiency.

El autoconocimiento como asignatura pendiente de la psicología en tanto ciencia humana
Authors:   Escuela Profesional de Psicología, Universidad de San Martín de Porres, Perú, Tello Leyva María Verónica
Published: September 2021

Entrelazar el autoconocimiento con la psicología, supone un análisis sereno y profundo sobre el camino recorrido por la psicología, desde su nacimiento hasta la actualidad; retomando su objetivo original de estudio: el alma humana. Este estudio, se sitúa inexorablemente en la esencia misma de la filosofía; lugar donde se gesta, forma y nace la psicología. Solo a partir de la filosofía y de la inclusión de la psicología en el campo de las ciencias humanas, se entiende el abandono que esta hace de su objeto original de estudio en su anhelo de ser reconocida como ciencia, pero sobre todo, se conocen las fortalezas y debilidades alcanzadas por la psicología contemporánea. Hecho que la coloca en una posición sumamente favorable para transitar, más que ninguna otra ciencia, dentro de los aspectos subjetivos como objetivos de la naturaleza humana, con relación a la máxima extraída del Templo de Delfos, tarea dejada por Sócrates: «conócete a ti mismo y conocerás a los demás». Lo que se plantea, es una nueva visión científica, desde el marco de una renovada psicología filosófica; y a partir de ahí, dar el salto cuántico de la ciencia a la metaciencia. El resultado, en la tarea de concretar la conquista del autoconocimiento, es lograr un punto de encuentro entre la naturaleza física y metafísica del ser humano.

Las enfermedades renales se producen por deterioro y/o alteración de los riñones que impiden su normal funcionamiento; por ello, los pacientes que sufren estas alteraciones son sometidos a diferentes tratamientos de diálisis. Se conoce que enfermedades sistémicas influyen en la presencia de la enfermedad renal crónica y esta a su vez podría generar manifestaciones en la salud general de las personas, incluyendo, por ende, a la cavidad oral. Estudios informan sobre manifestaciones orales que se producen en pacientes diagnosticados con enfermedad renal crónica que se encuentran bajo tratamiento. Las enfermedades orales muchas veces son producto de una mala higiene; sin embargo, las enfermedades sistémicas funcionan como factor de riesgo de enfermedades orales, llegando muchas veces a ser destructivas si es que no se manejan a tiempo y con un correcto diagnóstico. En el presente estudio, se explora la evidencia disponible de manifestaciones orales en pacientes con enfermedad renal crónica bajo tratamiento. El objetivo es controlar y mejorar el diagnóstico diferencial de las manifestaciones orales, así como, apuntar a un mejor tratamiento para la calidad de vida de los pacientes.

Authors: Jiang Rui , Zhao Yuquan , Wang Yongchen
Published: September 2021

Because of the overbearing low temperature, cold areas increase the morbidity and mortality of chronic non-communicable diseases (chronic diseases) in exposed populations. With the growth of the aging population and the superposition of lifestyle risk factors, the number of people with chronic diseases in cold areas is climbing, and the family and social burdens are rising. These health-threatening circumstances in the cold areas render the general practitioners to face serious challenges and difficulties in the community management of chronic diseases. This paper summarizes the current situation of chronic disease management in cold areas and explores the relevant management models so as to provide a useful reference for regional health construction, graded diagnosis and treatment, and prevention and control of chronic diseases in China.

Background

The aim of this study was to evaluate changes in prognostic risk profiles of women with endometrial cancer by comparing the clinical risk assessment with the integrated molecular risk assessment profiling.

Patients and methods

This prospective study recruited patients with biopsy proven endometrial cancer treated at the University Medical Centre Maribor between January 2020 to February 2021. Patient clinical data was assessed and categorized according to the currently valid European Society of Gynaecological Oncology, European SocieTy for Radiotherapy and Oncology, and European Society of Pathology (ESGO/ESTRO/ESP) guidelines on endometrial cancer. Molecular tumour characterization included determination of exonuclease domain of DNA polymerase-epsilon (POLE) mutational status by Sanger sequencing and imunohistochemical specimen evaluation on the presence of mismatch repair deficiencies (MMRd) and p53 abnormalities (p53abn).

Results

Fourty-five women were included in the study. Twenty-two tumours were of non-specific mutational profile (NSMP) (56.4%), 13 were classified as MMRd (33.3%), 3 were classified as p53abn (7.7%) and 1 was classified as POLE mutated (2.6%). Six tumours (15.4%) had multiple molecular classifiers, these were studied separately and were not included in the risk assessment. The clinical risk-assessment classified 21 women (53.8%) as low-risk, 5 women (12.8%) as intermediate risk, 2 women as high-intermediate risk (5.1%), 10 women (25.6%) as high risk and 1 patient as advanced metastatic (2.6%). The integrated molecular classification changed risk for 4 women (10.3%).

Conclusions

Integrated molecular risk improves personalized risk assessment in endometrial cancer and could potentially improve therapeutic precision. Further molecular stratification with biomarkers is especially needed in the NSMP group to improve personalized risk-assessment.

Published: September 2021

Per its English curriculum, vocabulary instruction is only integrated indirectly in the teaching of reading, writing, listening, and speaking skills in Malaysian schools. ESL learners then may overlook the variety of meanings that a word and its spelling can offer. This research aims to describe the effects of the explicit approach of vocabulary instruction on 30 Form Two (eighth grade) students from a suburban school in Ipoh, Perak, Malaysia. A descriptive style was adopted, and specific vocabulary lessons were used to help students learn the target words. Using descriptive statistics, vocabulary pre- and post-test scores were analysed and compared to determine the impact of this approach. The frequency counts, percentages, mean scores, and standard deviation of the students’ evaluation form responses were analysed. Content analysis was used to transcribe, classify, and categorise qualitative data from the interview session. According to the data, the students’ vocabulary scores increased dramatically in the post-test, with a mean gap of 21.9. The students were also enthusiastic about the teacher’s instructions (M=4.48, SD=0.64) and vocabulary lessons (M=4.34, SD=0.59). It is suggested that the explicit approach of vocabulary instruction, which engages students in exciting vocabulary learning techniques as employed by this study could enhance their vocabulary knowledge.

Authors: Setyowati Lestari , Sukmawan Sony
Published: September 2021

This study aimed to investigate the effect of using news as authentic materials for essay writing skills. This experimental study employed the one-group pre-test and post-test design to 18  fourth-semester students who joined the Essay Writing Course in one of the universities in Indonesia. These students were selected through systematic random sampling and went through treatments for 12 meetings where they were taught in a hybrid learning setting. The first four meetings used the conventional face-to-face classroom interaction. The rest of the meetings were done online because of the outbreak of COVID 19. The instruments to collect data were tests and documentation. Before they were given to the students, the teaching materials, pre-test, and post-test designs were tested and validated. The authentic materials were news texts about global issues such as poverty, environmental protection, gender, race and ethnicities, and diseases. Two raters scored the students’ writing by using Jacobs ESL Composition Profile. The researchers used IBM SPSS 25 software to analyze the data. The results of a paired sample t-test analysis showed that there was no significant difference in the students’ writing scores before and after using news as authentic materials (p = .959 α = 0.05). The paper further discusses the implications of this study for theoretical and practical use.

Published: September 2021

Critical thinking and self-voicing are two demanding skills that facilitate students to produce concise, authorial academic texts. While most writing programs and research have paid much attention to improving students’ writing achievement, less attention is given to promote these two skills in English as a Foreign Language (EFL) writing classrooms. This article reports a classroom-based study investigating the use of the Cooperative Integrated Reading and Composition (CIRC) technique to promote EFL students’ academic writing skills. It particularly examines how the CIRC technique helps to foster students’ critical and self-voicing stance in developing argumentative texts. A participatory qualitative study was employed, involving 64 undergraduate students majoring in English Education. Data were generated from the participants’ writing portfolios, observations, and the teacher’s reflections. The collected data were managed, classified, and analyzed using NVivo 12 to elicit the emerging themes. Drawing on the qualitative content analysis, the results showed that the CIRC technique helped to shape the participants’ critical thinking and self-voicing skills which were consistently demonstrated during the student-centered activities and their writing results. The participants could engage in productive writing processes, such as critical reading, note-taking, summarizing, drafting and revising composition, peer-reviewing, and other related collaborative skills. The findings indicated that the development of students’ critical thinking and self-voicing skills simultaneously affected the quality of their academic writing texts.

Большинство рассмотренных ранее работ решались в такой постановке, что физико-механические характеристики материала считались не зависящими от температуры. Однако для всестороннего анализа
прочностных характеристик необходимо учитывать связанность термоупругих полей. В данной работе
предложенная методика расчета принимает физико-механические характеристики зависящими от температуры и позволяет анализировать влияния температурной нагрузки на температурное поле и напряженно-деформированное состояния конструкции. На основании построенного алгоритма решения разработано программное обеспечение, позволяющее выполнить анализ влияния связанности термоупругих полей. Расчетные соотношения получены с помощью метода конечных биортогональных преобразований и справедливы для произвольного по времени внешнего температурного воздействия (граничные условия теплопроводности 1-го рода). Численный анализ результатов расчета показывает, что при
заданном внешнем температурном воздействии жесткость упругой системы оказывает существенное
влияние на ее термоупругое поле. При этом учет скорости изменения объема пластины приводит к
уменьшению температуры и механических напряжений в процессе прогрева пластины. В дальнейшем,
при постоянном температурном режиме, связанность полей не наблюдается. Разработанный алгоритм
расчета находит свое применение при проектировании ограждающих конструкций в виде однослойных
и многослойных пластин.

Влияние контактных взаимодействий сопряженных поверхностей
на уровень вибрации и шума механического пресса

Работа механизмов и машин в условиях динамических нагрузок, высоких скоростей и вибраций в значительной мере зависит от динамического контакта элементов конструкций в пределах предварительного смещения, т.е. до наступления процесса трения скольжения. Поэтому задачи снижения уровней вибрации и шума машин при их эксплуатации напрямую определяются контактной прочностью и жесткостью сопряженных поверхностей деталей. В данной статье авторы делают попытку установить закономерности влияния параметров механического контакта на уровень вибрации и шума работы пресса КЕ 2130 и в конченом итоге – разработать инженерный метод динамической оценки сочленений элементов. Для расчетов параметров происходящих процессов использовалась разработанная авторами динамическая модель упругого механического контакта в условиях трения покоя. Полученные данные экспериментально проверены на авторской оригинальной установке.

Анализ результатов исследований позволил сделать выводы о том, что уровень вибрации и шума при работе пресса зависит от характеристик контактирующих поверхностей деталей: параметров микрогеометрии шероховатого слоя, фактической площади соприкосновения, жесткости, физико-механических свойств материалов контактной пары, что и определяет новизну работы. На основании этого для заданных условий работы механического пресса были даны рекомендации, позволяющие снизить показатели вибрации и шума до допустимого предела. Впервые корректирование уровней вибрации машины проводилось с учетом контактной податливости ее сочленений.

Subject. The article discusses the region’s innovative development based on the circular economy principles.
Objectives. We analyze trends in the socio-economic development of the Sverdlovsk Oblast, which is based on the principles of the circular economy. We herein outline the strategy for establishing and running ecotechnology parks as a component of the region’s innovative development.
Methods. The study relies upon methods of logic, statistical, retrospective analysis. We applied the systems approach to evaluating the innovative development of the analyzable region in the mid-term run.
Results. The article showcases that the principles of the circular economy can be applied to unveil trends and factors of the region’s innovative development in terms of solid waste recycling. Implementing the ecotechnology park as a business model of the circular economy turns out to be a critical aspect of the region’s innovative development, which contributes to its competitiveness, since the business model is intended to address the depletion of national resources.
Conclusions. The circular economy policy should pursue the program-based innovative approach. The development and successful operation of the region’s environmental management will help disseminate investment and information flows, the consolidation of financial and intellectual resources of the region.
Monopol der Schweizerischen Depeschenagentur (sda) und Übernahmepraxis von Agenturberichten in der Presse (E-Book)
Authors: Eisenegger Mark , Oetiker Sibylle , Schranz Mario
Published: September 2021

Medienkrise, journalistischer Ressourcenschwund und Aktualitätsdiktat reduzieren die redaktionellen Eigenleistungen und erhöhen umgekehrt die Abhängigkeit der Redaktionen von fremdproduzierten Medieninhalten, wie sie Nachrichtenagenturen anbieten. Ein solcher Agentureinfluss bleibt für die Medienqualität nicht folgenlos. Diese Studie befasst sich mit der Übernahmepraxis von Agenturmaterial in der Schweizer Pressearena und analysiert die Auswirkungen des sda-Monopols. Folgende Fragen werden beantwortet: sda-Monopol: Hat das Inkrafttreten des sda-Monopols im Frühjahr 2010 zu einer Zunahme des sda-Einflusses in der Presseberichterstattung geführt? Agenturübernahmepraxis: Welche spezifischen Übernahmepraktiken lassen sich beschreiben und wie vertragen sich diese Praktiken mit zentralen journalistischen Qualitätsstandards? Werden Agenturmeldungen transparent gekennzeichnet oder weisen die Medien diese Quellen als eigene Beiträge aus? Mit welchen Verfahren werden Agenturmeldungen mit wenig Aufwand so ‘aufgepeppt’, dass sie den Eindruck redaktioneller Eigenleistung erwecken?  Hauptbefunde: Die Analyse zeigt eine signifikante Zunahme des sda-Einflusses in der Pressearena nach der Etablierung von deren Monopolstellung im Frühjahr 2010. Die vergleichende Analyse von Pressetiteln und ihren Online-Pendants zeigt ein fast durchgängiges, schwerwiegendes Qualitätsdefizit der Newssites. Die an ihn gerichteten Erwartungen kann der Onlinenachrichtenjournalismus grösstenteils nicht erfüllen. Die offline vorhandene Qualität, namentlich im Bereich der Abonnementspresse, wird im Onlinebereich bislang in keiner Weise erreicht. Auf Online steckt also nicht die Qualität drin, die der Reputation der Medienmarke, die offline erarbeitet worden ist, entspricht. Diese Studie ist – neben weiteren Vertiefungsanalysen – bereits im Jahrbuch 2011 Qualität der Medien publiziert worden (fög – Forschungsbereich Öffentlichkeit und Gesellschaft / Universität Zürich [Hg.]: Jahrbuch 2011 Qualität der Medien.

Medienkritik in der Schweiz - eine Bestandsaufnahme (E-Book)

Zahlreiche medienwissenschaftliche, auf die Schweiz, auf Deutschland und auf die USA bezogene Befunde legen den Schluss nahe, dass veröffentlichte Medienkritik ein ‘Mauerblümchendasein’ fristet. Diese Studie untersucht die Selbstbeobachtungsleistung des Medienjournalismus in der Schweiz. Folgende Fragen werden beantwortet: Strukturanalyse: Welche medienkritischen Instanzen gibt es in der Schweiz? Inhaltsanalyse: Welches quantitative Gewicht kommt journalistischer Medienkritik in den analysierten Zeitungen aus der Deutschschweiz zu? Welche inhaltlichen Schwerpunkte lassen sich eruieren?  Hauptbefunde: Es wäre wünschenswert, wenn Journalismus in der Lage wäre, das Mediensystem genauso kritisch zu beobachten wie andere Gesellschaftsbereiche. Es zeigt sich jedoch, dass von journalistischen Medien geleistete Medienkritik innerhalb der untersuchten Berichterstattung deutlich unterrepräsentiert ist. Im Zuge von Konzentrations- und Kommerzialisierungsprozessen im Mediensystem ergeben sich blinde Flecken und die Selbstbeobachtung wird zunehmend erschwert. Es braucht möglichst unabhängige Instanzen, die die Medien beobachten und dadurch zur öffentlichen Selbstbeobachtung  zwingen. Medienblogs bieten kein genügendes Äquivalent, da sie zu schwach institutionalisiert und deshalb eine unzureichend wirksame öffentliche Plattform für medienkritische Anliegen sind. Bei dieser Studie handelt es sich um eine Vorstudie des Forschungsvorhabens «Radar Medienkritik Schweiz» am Institut für Angewandte Medienwissenschaft der Zürcher Hochschule für Angewandte Wissenschaften in Winterthur.    Diese Studie ist – neben weiteren Vertiefungsanalysen – bereits im Jahrbuch 2012 Qualität der Medien publiziert worden (fög – Forschungsbereich Öffentlichkeit und Gesellschaft / Universität Zürich [Hg.]: Jahrbuch 2012 Qualität der Medien. Schweiz – Suisse – Svizzera. Basel: Schwabe, S. 361–376).
