Resilience and Stress at Professional Work: Analysis of the Research Landscape and Public Interest
No full textStress has a negative impact on the efficiency and productivity of employees and, accordingly, brings additional costs or losses to companies. A company’s proactive role in ensuring its employees’ resilience to stress in the workplace is crucial in creating an effective working environment and reducing staff turnover. The article analyses the scientific environment (using Descriptive bibliometric analysis and Science Mapping) and public interest (using Google Trends) in resilience and stress at professional work and in management in this area. The bibliometric analysis was conducted using VOSviewer based on publications from the Scopus database (Elsevier) without restrictions on the year of publication, country, author, language and category; the trend analysis was conducted for the period 2004‒2024 for all categories and countries, all Internet traffic was restricted to “Web searches”. The study showed a steady increase in Internet searches for the concept of “resilience training”, with peaks in 2004 and 2005 (coinciding with known terrorist attacks); interest in the query “resilience at professional work” is highest in the United States and the United Kingdom, and 12 leading countries were identified for the query “stress at professional work”. The dynamics of scientific papers in this area are described in the article by a 3rd-degree polynomial dependence equation with a determination coefficient of R² = 0.9676; a significant surge in publication activity occurred in 2014, with the number of papers increasing by 472% and an annual growth rate of 20% in 2014‒2024. The dominant subject areas of these publications are medicine (34.50%), social sciences (15.08%) and psychology (14.47%); countries are the USA, the UK, Australia, Canada, and China. The article identifies scientists who are leaders of scientific thought in this area, the most developed research networks, authoritative publications and journals (based on citation analysis), the most powerful international and national institutions that have funded research in this area (among the world leaders are the US National Institutes of Health and the US Department of Defence). The article structures the scientific work in this area: 1) based on the content and contextual feature, nine thematic clusters are identified, the most significant of which is the one that studies stress at work and professional burnout from a medical point of view; 2) based on the content and chronological feature, the most significant number of works were those on the human factor and gender issues of stress and resilience published in 2017‒2018
Agile Method in Social Work with Children and Adolescents Exhibiting Conduct Disorder and Antisocial Behaviour: Case of Kidsköpfe gGmbH
No full textThis article explores the application of the SCRUM methodology, a popular Agile framework, in social work with children and adolescents exhibiting conduct disorders and antisocial behaviour. Traditional social work models often struggle to adapt to the rapidly changing and complex needs of this high-risk population. The SCRUM framework, with its emphasis on continuous feedback, iterative processes, and interdisciplinary collaboration, offers a flexible and dynamic approach to care. By fostering teamwork between social workers, psychologists, and medical professionals, SCRUM facilitates real-time adjustments in interventions based on the evolving needs of the child. The article examines the benefits of empowering social work teams through SCRUM’s decentralized decision-making, which allows for proactive responses in crisis situations. The KIDSKöpfe gGmbH case study illustrates how SCRUM can be applied in practice, resulting in improved outcomes for children with complex behavioural issues. Despite the potential advantages, there remains a significant gap in the literature on SCRUM’s application in social work, particularly in managing conduct disorders. The article concludes by emphasizing the need for further research and case studies to explore SCRUM’s long-term impact in social work settings, particularly in addressing institutional barriers and regulatory challenges. The discussion highlights SCRUM’s potential to revolutionize social work by creating more flexible, responsive, and collaborative systems for managing high-risk children and adolescents

Diagnosis A species of Stygiiulus stat. nov. with normal mouthparts. Clearly distinguishable from congeners by the very distinctive structure of the opisthomere (Fig. 10F) including a right- to acute-angled posterior hump pointing distad, a large, (sometimes) bipartite velum (with a posteriorly positioned distal outgrowth (do), this being much less prominent than in S. insularis comb. nov. and S. seewaldi comb. nov.), with the main part being mostly smooth (barely serrated), and a solenomere distally forming a stout anterior and a much more slender posterior branch, both apically finely ciliate; some specimens with a minute third thumb-like branch basally to the posterior branch. In addition, this species (except for its dubious subspecies T. t. pygmaeus, see below) differs from all other Stygiiulus stat. nov. species by the presence of a very long and upwards curved epiproct. Material examined ITALY • 2 ♂♂, 1 ♀; Veneto, Altopiano dei Sette Comuni, Vastagna (VI), Grotta [cave] del Subiolo (135 V/VI); 169 m a.s.l.; 4 Mar. 1990; G. Peretto and E. Piva leg.; H. Enghoff det. 2013; NHMD. Descriptive notes ANTENNAE. 2.2–2.4 times as long as head and 1.65–1.7 as long as H in males, and 1.9–2 and 1.3– 1.4 times, respectively, in females; antennomere 5 2.6–2.9 times as long as broad; antennomeres 2, 3 and 5 subequal in length, slightly longer than 4, and 1.4–1.5 times as long as 6. TARSUS OF MID- BODY LEGS. 1.8–1.9 times as long as tibia and 2.8–4.3 times as long as apical claw. Midbody legs ca 1.25 times as long as H in males, and equal in length in females. FEMALE SEXUAL CHARACTERS. Leg-pairs 1 and 2 considerably thicker and shorter than following legs. Vulva (Fig. 11D) nearly symmetric; bursa slightly compressed in the sagittal plane; each valve distally with one vertical row of several setae; a similar row present on each side sclerite; operculum (op) very thick, subconical, i.e., tapering to a distinct blunt apex, exceeding bursa by ca 1 ⁄ 5 of total height of vulva, distally with a dense bunch of setae each side. Receptaculum seminis consisting of two long and narrow, closely adjacent tubes of equal length – a twisted lateral one (lt) leading to a small piriform ampulla (la), and a mostly straight mesal one (mt) ending in a somewhat larger ovoid ampulla (ma). Distribution Known from numerous caves and one epigean locality in the central Venetian Prealps, as well as from several caves in Monti Lessini (extreme south of the Venetian Prealps). Also known from two caves on the southern slopes of Dolomiti (Fig. 13, white squares). Remarks In the past, this taxon was treated as a member of Mesoporoiulus Verhoeff, 1905. Vagalinski et al. (2015) hypothesized it could be a somewhat deviating member of Stygiiulus. Here we fully confirm this assumption and formally transfer tobias to the genus Stygiiulus. The subspecies S. t. pygmaeus (Manfredi, 1953) comb. nov. has already caught the attention of Strasser (1962). On page 60 of the latter work, the author commented on the significant size difference between pygmaeus (23 mm of length) and the typical tobias (50–67 mm of length), and also emphasized the apparent confusion of Manfredi (1953b) regarding the gonopods of her newly described subspecies, which she stated to match well (along with most other characters) to the descriptions of tobias given by both Attems (1927) and Verhoeff (1930). In fact, what Attems (1927) recorded and depicted was S. maximus comb. nov. (see Remark under the latter species). The short and straight epiproct in pygmaeus (as originally described), unlike the long and upwards curved process in the typical form, adds further uncertainty about the identity of Manfredi’s subspecies. We agree with Strasser’s (1962) opinion that pygmaeus most likely represents a separate species. However, its status can only be resolved after examination of type or topotype material. The gonopods of the two presently examined males from Grotta del Subiolo differ fromVerhoeff’s(1930) drawings based on material from Grotta Parolini near Vastagna and/or “Bus de la Bela” near San Donato, prov. Belluno, by a blunt and finely serrated, rather than tapering and ciliate, posterior part of velum, and by an apically tri- instead of bipartite solenomere. In Grotta della Bigonda, this species lives in sympatry with S. ausugi comb. nov.Published as part of Vagalinski, Boyan, Borissov, Simeon, Bobeva, Aneliya, Canciani, Giacomo & Antić, Dragan Ž., 2022, The mostly cavernicolous millipede genus Stygiiulus Verhoeff, 1929, stat. nov.: taxonomy, distribution and phylogenetic relationships (Diplopoda, Julida, Julidae), pp. 30-69 in European Journal of Taxonomy 798 on pages 55-57, DOI: 10.5852/ejt.2022.798.1669, http://zenodo.org/record/632300
Ethical Practices in Modern Academia: Does Length of Educational Experience and Quality of Governance Contribute to a Deeper Understanding of Academic Integrity?
No full textAcademic integrity is a fundamental component of higher education, yet its enforcement varies across countries due to differences in educational development and governance structures. This study investigates the relationship between educational indicators – Expected Years of Schooling and Mean Years of Schooling – and plagiarism levels, as measured by similarity percentages in checked documents. Additionally, the study examines the role of governance quality, represented by the Rule of Law index, in influencing plagiarism levels. The research utilises Plagiarism Checker X data as of February 1, 2024, providing the most recent plagiarism similarity percentages, while the educational indicators (Expected Years of Schooling and Mean Years of Schooling) and the Rule of Law index are based on the latest available data from 2022. A statistical analysis was conducted using Generalized Additive Models (GAM) and quadratic polynomial regression to identify potential non-linear relationships among these variables. The results indicate that Mean Years of Schooling have a statistically significant non-linear effect on similarity percentages, with a peak influence around 6–8 years before levelling off. Expected Years of Schooling also exhibits a weak but statistically significant negative relationship with similarity percentages, suggesting that higher schooling expectations contribute to reducing plagiarism. In contrast, the Rule of Law does not directly impact similarity percentages, implying that governance quality alone is not a strong predictor of academic integrity. A comparison between GAM and polynomial regression models shows similar explanatory power, with GAM offering greater flexibility in capturing non-linear patterns while polynomial regression provides a more explicit interpretative framework
Stability of Production Prices: A Modification to the Full-Cost Approach.
No full textAn approach to the problem of the stability of production prices generalizing the full-cost approach is proposed. It is based on comparing current profit rates with a target level: if the current profit rate in a sector is lower (higher) than the target level, the price of the product of this sector increases (decreases). It is proved that this leads to stability of the production prices in two models with fixed capital. In the first model, it is assumed that the author is given a nominal wage rate and that the target profit rate is formed exogenously. In the second model, he is implicitly given a real wage rate and the target profit rate is formed endogenously. Copyright 1999 by Blackwell Publishers Ltd and The Victoria University of Manchester
New bounds on the covering radius of the second order Reed-Muller code of length 128
No full textIn 1981, Schatz proved that the covering radius of the binary Reed- Muller code RM (2, 6) is 18. It was previously shown that the covering radius of RM(2,7) is between 40 and 44. In this paper, we prove that the covering radius of RM(2,7) is at most 42. As a corollary, we also find new upper bounds for RM (2, n), n = 8, 9, 10. Moreover, we give a sufficient and necessary condition for the covering radius of RM(2,7) to be equal to 42. Using this condition, we prove that the covering radius of RM(2,7) in RM(4,7) is exactly 40, and as a by-product, we conclude that the covering radius of RM(2,7) in the set of 2-resilient Boolean functions is at most 40, which improves the bound given by Borissov et al. (IEEE Trans. Inf.

Measurement of spin correlation between and antitop quarks produced in p¯p collisions at √s=1.96 TeV
No full textWe present a measurement of the correlation between the spins of t and t quarks produced in proton–
antiproton collisions at the Tevatron Collider at a center-of-mass energy of 1.96 TeV. We apply a matrix
element technique to dilepton and single-lepton+jets final states in data accumulated with the D0 detector
that correspond to an integrated luminosity of 9.7 fb⁻¹. The measured value of the correlation
coefficient in the off-diagonal basis, 0ₒff = 0.89 ± 0.22 (stat + syst), is in agreement with the standard
model prediction, and represents evidence for a top–antitop quark spin correlation difference from zero
at a level of 4.2 standard deviations

Search for single production of vector-like quarks decaying into Wb in pp collisions at √s = 13 TeV with the ATLAS detector
No full textA search for singly produced vector-like quarks Q, where Q can be either a T quark with charge +2/3 or a Y quark with charge −4/3, is performed in proton–proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 36.1 fb−1, recorded with the ATLAS detector at the LHC in 2015 and 2016. The analysis targets Q → Wb decays where the W boson decays leptonically. No significant deviation from the expected Standard Model background is observed. Upper limits are set on the QWb coupling strength and the mixing between the Standard Model sector and a singlet T quark or a Y quark from a (B, Y) doublet or a (T, B, Y) triplet, taking into account the interference effects with the Standard Model background. The upper limits set on the mixing angle are as small as |sin θL| = 0.18 for a singlet T quark of mass 800 GeV, |sin θR| = 0.17 for a Y quark of mass 800 GeV in a (B, Y) doublet model and |sin θL| = 0.16 for a Y quark of mass 800 GeV in a (T, B, Y) triplet model. Within a (B, Y) doublet model, the limits set on the mixing parameter |sin θR| are comparable with the exclusion limits from electroweak precision observables in the mass range between about 900 GeV and 1250 GeV.[Figure not available: see fulltext.] © 2019, The Author(s)
