Bisherige Studien über energetische Flexibilität in der deutschen Industrie weisen das vorhandene Flexibilitätspotenzial mit hoher Streuung aus. Diese Arbeit analysiert relevante Studien in Bezug auf deren Annahmen und Vorgehensweise. Aufbauend auf den bisherigen Vorgehensweisen wird ein Ansatz zur Erhebung der Daten im Produktionssystem vorgestellt. Des Weiteren wird eine Methode zur Aggregation der Daten hoch bis auf Branchenebene entwickelt.   Previous studies on the energetic flexibility of German industry show potentials with a large spread. Therefore, in this article, a systematic analysis of the individual studies and an evaluation of the indicated flexibility potentials are carried out. Based on the existing methods, a bottom-up approach for collecting the data in the production system and the aggregation up to the industry level is presented.

Ebben a tanulmányban arra a kérdésre keressük a választ, hogy a főképp nyugati tudományos kutatói környezetben megtermelt, kortárs tudományos eredményekben hogyan jelenik meg a média és a muszlimok viszonya, valamint, hogy ezen eredmények létrejöttének körülményeiben milyen hasonlóságokat és eltéréseket lehet felfedezni. Az Európát az IS közép-keleti tevékenysége, a szíriai polgárháború és más okok miatt az elmúlt években egyre nagyobb mértékben érinti a muszlim bevándorlás jelensége. Ez, továbbá a bevándorló muszlimok és a többségi nemzet közti interakciók problémái indokolttá teszik ezeknek a közelmúltbeli tudományos eredményeknek részletesebb, a tematizáció, a geográfiai eloszlás, a vizsgált minták és a mintaméret, az adott kutatáshoz elnyert támogatások és más egyéb releváns szempontok szerinti metaelemzését. A következőkben bemutatjuk a kitűzött célok megvalósítását egy N=160 szakcikkből álló mintán, a muszlimokról szóló kutatások (N=33) kiválogatását követő szisztematikus analízis lefolytatásával és a média szerepét és hatását vizsgáló tematikus elemzéssel. Azt találtuk, hogy a vizsgált mintán belül a médiában megjelenő muszlim-képek három fő típusa azonosítható: Az erőszakot individuális vagy állami szinten alkalmazó entitás, az erőszakot elszenvedő áldozat, illetve a „nyugattal” kulturálisan és viselkedésileg szembenálló idegen. --- Moving Images: a Systematic Analysis on the Media Representation of Muslims in Recent Sociological Research In this study, we are looking for an answer to the question of how the relation of media and muslims is represented in contemporary scientific results, produced mostly in a western research environment and, furthermore, of what similarities and differences can be shown between the circumstances characterizing the emergence of these results. As a result of IS’s activities in the Middle East, of the current civil war in Syria and of other causes, Europe is increasingly affected by the phenomenon of muslim immigration. This, as well as the problematics of national majority-Muslim minority interactions make the goal of conducting a meta-analysis of recently published results reasonable, focusing on issues of thematization, geographical distribution, analyzed samples and sample sizes as well as on grants obtained by the authors for a specific research. In the following, we realize our research objectives through conducting a systematic analysis on a section (N=33) of a larger (N=160) sample of peer-reviewed articles, and by a thematic analysis of the same section focusing on the role and influence of various media. We found that within the sample, images of Muslims in the media can be categorized in three main types: An entity using violence at the individual or state level, a victim of violence, and an outsider culturally or behaviorally in defiance of the West.

‘Classic’ forest plots show the effect sizes from individual studies and the aggregate effect from a meta-analysis. However, in ecology and evolution meta-analyses routinely contain over 100 effect sizes, making the classic forest plot of limited use. We surveyed 102 meta-analyses in ecology and evolution, finding that only 11% use the classic forest plot. Instead, most used a ‘forest-like plot’, showing point estimates (with 95% confidence intervals; CIs) from a series of subgroups or categories in a meta-regression. We propose a modification of the forest-like plot, which we name the ‘orchard plot’. Orchard plots, in addition to showing overall mean effects and CIs from meta-analyses/regressions, also includes 95% prediction intervals (PIs), and the individual effect sizes scaled by their precision. The PI allows the user and reader to see the range in which an effect size from a future study may be expected to fall. The PI, therefore, provides an intuitive interpretation of any heterogeneity in the data. Supplementing the PI, the inclusion of underlying effect sizes also allows the user to see any influential or outlying effect sizes. We showcase the orchard plot with example datasets from ecology and evolution, using the R package, orchard, including several functions for visualizing meta-analytic data using forest-plot derivatives. We consider the orchard plot as a variant on the classic forest plot, cultivated to the needs of meta-analysts in ecology and evolution. Hopefully, the orchard plot will prove fruitful for visualizing large collections of heterogeneous effect sizes regardless of the field of study.

Изменения, происходящие в обществе, усложнение профессиональных задач делают актуальным запрос к высшими учебными заведениями о подготовке специалистов к инновационной деятельности. Для развития инновационного потенциала студентов современный образовательный процесс в высшем учебном заведении должен иметь личностно-профессиональную направленность. Значимым фактором развития инновационного потенциала студентов является образовательная среда и психолого-педагогическое сопровождение образовательного процесса. Changes in society, the complexity of professional tasks actualize the request to universities to train specialists who are ready for innovation. To develop the innovative potential of students, the modern educational process in universities should be focused not only on the professional training of students, but also on the development of personality. Innovative activities, solving creative tasks to create new products and technologies require active work of the intellect, motivation and will, and this stimulates the development and selfdevelopment of a person. An important factor in the development of innovative potential of students is the educational environment. The functioning of this environment should be based on a systematic analysis of the object, subject, processes, and conditions of innovative development. In addition, it is important to determine the criteria for the effectiveness of the innovation environment, as well as to implement the principle of ensuring the continuous development of students. For the development of innovative potential, it is necessary to use psychological and pedagogical support of the educational process. The main principle of psychological and pedagogical support of the educational process is to take into account the individual characteristics and capabilities of students, the development of their resources. Psychological and pedagogical support of the educational process should be aimed primarily at the actualization of personal competencies that determine innovative activity. For the development of innovative potential, students should participate in the choice of an individual educational trajectory, show educational initiatives and implement them in research activities.

Coronaviruses have been responsible for major epidemic crises in 2003 with SARS-CoV-1, in 2012 with MERS-CoV and in 2019 with SARS-CoV-2 (COVID-19), causing serious atypical pneumonia in humans. We intend, with this systematic analysis and meta-analysis, to clarify the prevalence of the various strains of coronavirus in different animal species. For this purpose, we carried out an electronic survey using Pubmed's Veterinary Science search tool to conduct a systematic assessment of published studies reporting the prevalence of different strains of coronavirus in different animal species between 2015 and 2020. We conducted different analysis to assess sensitivity, publication bias, and heterogeneity, using random and fixed effects. The final meta-analysis included 42 studies for systematic review and 29 in the meta-analysis. For the geographic regions with a prevalence greater than or equal to 0.20 (Forest plot overall; prevalence = 0.20, p < 0.01, Q = 10476.22 and I2 = 100%), the most commonly detected viruses were: enteric coronavirus (ECoV), pigeon-dominant coronavirus, (PdCoV), Avian coronavirus M41, Avian coronavirus C46, Avian coronavirus A99, Avian coronavirus JMK, MERS-CoV, Bovine coronavirus, Ro-BatCoV GCCDC1, Alphacoronavirus, Betacoronavirus, Deltacoronavirus, Gamacoronavirus and human coronaviruses (HCoVs). The wide presence of different strains of coronavirus in different animal species on all continents demonstrates the great biodiversity and ubiquity of these viruses. The most recent epidemiological crises caused by coronavirus demonstrates our unpreparedness to anticipate and mitigate emerging risks, as well as the need to implement new epidemiological surveillance programs for viruses. Combined with the need to create advanced training courses in One Health, this is paramount in order to ensure greater effectiveness in fighting the next pandemics.

Summary Globodera pallida is the most damaging pest of potato in the UK. This work underpins enhancement of a well-established, web-based scenario analysis tool for its management by recommending additions and modifications of its required inputs and a change in the basis of yield loss estimates. The required annual decline rate of the dormant egg population is determined at the individual field sample level to help define the required rotation length by comparing the viable egg content of recovered cysts to that of newly formed cysts for the same projected area. The mean annual decline was 20.4 ± 1.4% but ranged from 4.0 to 39.7% annum−1 at the field level. Further changes were based on meta-analysis of previous field trials. Spring rainfall in the region where a field is located and cultivar tolerance influence yield loss. Tolerance has proved difficult to define for many UK potato cultivars in field trials but uncertainty can be avoided without detriment by replacing it with determinacy integers. They are already determined to support optimisation of nitrogen application rates. Multiple linear regression estimates that loss caused by pre-plant populations of up to 20 viable eggs (g soil)−1 varies from ca 0.2 to 2.0% (viable egg)−1 (g soil)−1 depending on cultivar determinacy and spring rainfall. Reliability of the outcomes from scenario analysis requires validation in field trials with population densities over which planting is advisable.

Background/Aims: Gastric cancer (GC), the third-leading cause of cancer death in the world, is typically diagnosed only in its advanced stages. WNT signaling has been associated with clinicopathological characteristics in diverse cancer types. But the systematic analysis of WNT5A, a member in the signaling, has not been inspected. Thus, our study used a meta-analysis to statistically associate WNT5A expression with GC clinicopathological characteristics. Methods: For a systematic literature review of GC in combination with the WNT signaling molecule WNT5A, we searched for PubMed, Cochrane Library, and Web of Science. It led to the five cohorts, in four eligible studies, consisting of 1,034 patients (617 WNT5A-positive and 417 WNT5A-negative patients). These patients were inspected by the library “meta” in R software for our meta-analysis. Results: Our meta-analysis, revealed a statistically significant associations of WNT5A-positivity with lymph node metastasis (p=0.0047), some types of Lauren diffuse subtype GCs (p<0.0001), advanced tumor depth (p<0.0001), and advanced UICC stages (p=0.0461) with no observation of bias or confounding factors. Conclusions: These results support the feasibility of targeting this embryonic signaling pathway, both for therapy, and as a biomarker to “guide” various individual interventions (i.e., “personalized medicine”).

Presented is research in the problem of political socialization of the youth. Socialization of individual plays the role as a way of forming a political picture of the world among young people, determining degree of participation in management of society that is an important component of the process of socialization of the individual as a whole. At the same time, today there is no holistic understanding of institutions through which the process of political socialization of youth can be carried out. The main purpose of this work is to conduct a systematic analysis of the list of forms of direct participation of young people in political life of society as a means of political socialization. In this regard, the authors have classified these forms into two groups, i.e. traditional ones, established by special laws forms of political participation of citizens in the life of the country, and alternative ones, implemented in the framework of state youth policy. On the basis of research results of the department of political psychology, faculty of philosophy of Lomonosov Moscow State University, aimed at comparative analysis of the nature of political socialization and re-socialization of different age groups, substantiated is gradual decrease in the role of traditional institutions in political socialization with variety of alternative ones. Also defined are place and role in the life of modern young person of such institutions as elections, political parties and various forms of youth self-government.
