Can coercion in psychiatry be justified? A theoretical adversarial collaboration approach.

This study, titled “Motivation of Teachers of Physical Education and Sports for Choosing a Secondary Education Profession,” aimed to investigate whether teachers of Physical and Sports Education are motivated in their choice of the secondary education profession. The research addressed the general hypothesis that there is motivation among these teachers to choose this career, with two partial hypotheses suggesting that their choice may be driven by both internal and external motivations. The study relied on a descriptive analytical method, and the research community consisted of 203 teachers of Physical and Sports Education in the State of Sétif, from which a random sample of 43 teachers was selected. Data were collected using a questionnaire. The results revealed that there is indeed motivation among teachers who chose to teach Physical and Sports Education in secondary schools. This motivation appeared in two forms: internal motivation, which proved to be more influential, and external motivation, which had a lesser impact. Among internal motivations, psychological and personal motives were the most significant, followed by cognitive motives. Regarding external motivations, the most influential were work environment factors, followed by social motives, professional motives, and finally, family and friends, which had the least effect on the teachers’ choice.

In this article, we are concerned with the generalization performance of nonparametric estimation for pairwise learning. Most of the existing work requires the hypothesis space to be convex or a VC-class, and the loss to be convex. However, these restrictive assumptions limit the applicability of the results in studying many popular methods, especially kernel methods and neural networks. We significantly relax these restrictive assumptions and establish a sharp oracle inequality of the empirical minimizer with a general hypothesis space for the Lipschitz continuous pairwise losses. As an example, we apply our general results to study pairwise least squares regression and derive an excess population risk bound that matches the minimax lower bound for the pointwise least squares regression. The key novelty lies in constructing a structured deep ReLU neural network to approximate the true predictor, and in designing a targeted hypothesis space composed of networks with this structure and controllable complexity. Experiments validate the effectiveness of the proposed method. This example demonstrates that the obtained general results indeed help us to explore the generalization performance on a variety of problems that cannot be handled by existing approaches.

Abstract We provide a mathematically rigorous Keldysh functional integral for fermionic quantum field theories. We show convergence of a discrete-time Grassmann Gaussian integral representation in the time-continuum limit under very general hypotheses. We also prove analyticity of the effective action and explicit bounds for the truncated (connected) expectation values $$\gamma ^\textrm{c}_{m,\bar{m}}$$ γ m , m ¯ c of the non-equilibrium system. These bounds imply clustering with a summable decay in the thermodynamic limit, provided these properties hold at time zero, and provided that the determinant bound $$\delta _C$$ δ C and decay constant $$\alpha _C$$ α C of the fermionic Keldysh covariance are bounded uniformly in the volume. We then give bounds for these constants and show that uniformity in the volume indeed holds for a general class of systems. Finally we show that in the setting of dissipative quantum systems, these bounds are not necessarily restricted to short times.

The increased rate of artificial intelligence use within the media industry has led to the‎ emergence of new ethical problems, as well as the expansion of existing ones. Considering various factors‎ and agents, finding a unique solution to these ethical issues would be a highly complex and arguably ‎impossible undertaking. The general hypothesis of this paper is that current ethical problems related to‎ the use of artificial intelligence in the media can be separated into two main categories: solvable and‎ insolvable. The analysis of the relevant literature will cover the most prominent ethical problems and ‎enable their classification according to the previously mentioned categories. The primary aim of this‎ paper is to present which of the existing ethical issues, categorized as solvable, should be prioritized‎ in future research, in order to eventually find a solution. The group of unsolvable issues should not be‎ completely ignored, but decrease in research frequency is suggested, in line with the advancement of‎ more sophisticated AI models that may be better suited for ethical integration into media practices.‎

This study explored Alpha band activity during automaticity in self- and externally-paced basketball tasks, per the Fitts and Posner model. Twenty male basketball players volunteered, split into elite and trained groups. Alpha band power was analyzed using repeated measures ANOVA (α = 0.05). Results showed elite athletes had greater Alpha band activation than the trained group across both tasks. Alpha band activation was also higher in the free-throw task compared to pass-catching. This difference was more pronounced in the elite group; the trained group showed no significant Alpha band activity difference between tasks. Detailed elite group analysis revealed the free-throw task elicited higher Alpha band power in most cortical regions (excluding temporal and occipital areas) compared to pass-catching. Alpha band activity for the free-throw task was greater in the seconds leading up to execution, but no difference was observed between the two tasks during the actual execution. While self-paced findings align with the general neural efficiency hypothesis, elite Alpha band modulations during externally-paced tasks are better explained by the net neural efficiency and pulsed inhibition hypotheses. Overall, these findings highlight the need to revise neural-efficiency accounts from self-paced skills, explicitly considering perceptual–attentional processing demands imposed by dynamic, reactive, externally paced tasks.

In modern medical science, the definition of «iatrogenism» is not presented in a specific unified form. In this regard, its various variations contain different semantic content, forming certain derivatives for the interrelated concept of «iatrogenic condition» of personnel. The aim is to analyze the causes of iatrogeny in the general hypothesis of the topic of the work, based on previous studies, when trying to distinguish the terms «iatrogenism» and «iatrogenic condition» in a certain perspective of the place of these phenomena in modern healthcare. Materials and methods. The paper uses the method of a systematic review of the works of domestic and foreign authors previously published on the stated topic, which are in the public domain. Results. It is proposed to supplement the definition of «iatrogeny» with the phrase «iatrogenic condition» based on the factors of negative consequences in the professional activity of a physician. Conclusion. It is necessary to take into account the concomitant causes and circumstances that led to the occurrence of iatrogenic conditions in personnel and iatrogenism in general. In this context, the doctor’s responsibility will be to prevent potential iatrogenic conditions. In addition to the legal aspect, targeted actions that fall into the category of violations of moral and ethical standards and are aimed at intentionally harming the patient deserve special attention. Given the social importance of healthcare in general, it is necessary to further study in detail the problems of iatrogenism and iatrogenic conditions of personnel in order to practically eliminate the prerequisites for their formation, starting from the period of training of medical specialists in higher and secondary specialized educational institutions.

The adolescent period represents a critical stage in human development, marked by profoundbiological, psychological, and social transformations. In this context, planned physical activity,adapted to age level, plays a fundamental role in supporting maturation processes both at theneuromuscular level and in cognitive and emotional structures. The research objectives aim not onlyto evaluate the immediate changes produced by the spinning intervention but also to formulate practical recommendations for incorporating this method into school programs. The general hypothesis of the study is that students’ participation in spinning training will lead to significant improvements in all dimensions of psychomotor skills compared to a control group. The study included a total of 50 students, selected from five representative high schools in Suceava County: “Spiru Haret” Theoretical High School, Economic College, Pedagogical College, Food Industry High School, and “Petru Rareș” National College. Thus, motor coordination and static balance showed notable improvements, confirming that pedaling with variable rhythms and posture changes on the bike (sitting/standing in the pedals) stimulate neuromotor control mechanisms and proprioception. Additionally, lower-limb explosive strength developed significantly as a result of pedaling with increased resistance and intervaltype training, which replicated demands similar to plyometric exercises. At the physiological level, both aerobic endurance (measured by the 6-minute test) and anaerobic capacity (evaluated by the Wingate test) showed clear progress. The preliminary results support the general hypothesis that a structured spinning program can contribute to the multidimensional development of high school students’ psychomotor potential.

ABSTRACT The psychological mechanisms linking attachment insecurity to social anxiety disorder (SAD) are not fully understood. We propose an empathy-based schema generalization model, positing that the association between attachment insecurity and SAD is explained by dysregulated empathy toward significant others, with these patterns generalizing to new relationships. Across four studies (N = 952) with international, Turkish, and Polish samples (including a clinical group), participants brought to mind a significant other and an acquaintance before reporting empathy toward each. For attachment anxiety, the association with SAD was sequentially mediated by higher personal distress toward a significant other and lower self-compassion. For attachment avoidance, the association was mediated by lower empathic concern toward a significant other. Crucially, these mediational pathways were specific to significant others and held after adjusting for empathy toward acquaintances. Supporting the generalization hypothesis, attachment insecurities were associated with empathy toward acquaintances indirectly, through their association with empathy toward significant others. In the clinical sample, the indirect effect of attachment avoidance on SAD via empathic concern toward a significant other was moderated by self-compassion and socioeconomic status, revealing a key boundary condition. This research illuminates how relational schemas of empathy, rooted in close bonds, are linked to social fears.

Objective: To establish the relationship between teaching tutoring and academic training in students of the x semester - Professional School of Physical Education of the UNMSM Faculty of Education. Materials and Method: For this correlational study, applied two questionnaires belonging to each variable (X and Y) to a sample of 108 students, then processed in the SPSS program. Results: The general hypothesis found a moderate correlation of Rho = 0.463, since the Tutoring of teachers is considered by regular students, which affects the academic competences considered indifferent. The first and second specific hypotheses identified a low correlation of Rho = 0.390 and Rho = 0.358, respectively; while the third and fourth specific hypotheses determined a moderate correlation of Rho = 0.500 and Rho = 0.506, respectively. Conclusion: The tutoring action, represented by effective communication, conflict management, participation and teamwork, and time planning, are not developing efficiently, which damages the strengthening of their academic competences.

Importance sampling (IS) is commonly used for cross validation (CV) in Bayesian models, because it only involves reweighting existing posterior draws without needing to re-estimate the model by re-running Markov chain Monte Carlo (MCMC). For hierarchical models, standard IS can be unreliable; the out-of-sample generalization hypothesis may involve structured case-deletion schemes which significantly alter the posterior geometry. This can force costly MCMC re-runs and make CV impractical. As a principled alternative, we tailor adaptive sequential Monte Carlo to sample along a path of posteriors that leads to the case-deleted posterior. The sampler is designed to support various hypotheses by accommodating diverse CV designs, and to streamline the workflow by automating path construction and systematically minimizing MCMC intervention. We demonstrate its utility with three types of predictive model assessment: longitudinal leave-group-out CV, group K-fold CV, and sequential one-step-ahead validation.

The development of the research study aims to address the repercussions of the influence exerted by the parliamentary functions of Congress concerning the maintenance and development of the balanced principle of Separation of State Powers. It conducts a basic methodological study with a descriptive level, correlational design, and analytical-quantitative approach, using a survey applied to a significant sample of 108 constitutional experts from the city of Lima. The general research hypothesis is validated with a Spearman coefficient of 0.693, indicating a very close and binding relationship between the exercise of congressional functions by the Legislative Power and the practicable development of the principle of separation of powers, but from a perspective of negative influence. This is particularly evident as the Congress of the Republic has been exercising a highly questioned oversight function over the Executive in the last fourteen years, with significant political interference from the Legislative branch during the presidential terms of 2016-2020, 2021-2022, and 2023-2025. This has led to a problematic situation where the Legislative Control of Congress tends to be overly politicized, adversely affecting the normal functional-political and democratic-constitutional performance of the Executive. The main conclusion is that there is a significant relationship between the exercise of Congress's functions and the principle of separation of powers; however, the increasing politicization of legislative control over the Executive is generating a political and social crisis in the country, increasing citizen distrust towards state institutions.

The implementation of artificial intelligence (AI) in the public sector represents a significant step toward improving governmental decision-making processes. AI systems reduce human errors, enable faster and more accurate analysis of large data volumes, and increase efficiency in crisis situations. A key aspect lies in creating strategic frameworks that foster transparency, accountability, and objectivity within government institutions. This study aims to explore the impact of AI systems on optimizing strategic decision-making and to analyze the strategies that governmental stakeholders may apply for successful implementation. The general hypothesis assumes that the use of AI positively affects strategic decision-making, while the specific hypotheses address the reduction of human errors and the protection of citizens’ privacy as key factors for effective implementation. The theoretical and practical contribution of the study lies in the potential to improve governance practices in the public sector, increase citizens’ trust, and enhance the creation of sustainable public value.

The study of school climate and its influence on students’ anxiety in secondary education represents a current and significant topic within educational and social psychology. Numerous studies confirm that a positive and supportive school atmosphere is crucial for students’ psychological well-being and academic progress. Anxiety is one of the most prevalent challenges among adolescents, capable of impairing cognitive performance, emotional balance, and social adaptation. Given that adolescence is a critical stage of personal and social development, anxiety may have lasting effects on mental health and life opportunities. This preliminary study aimed to examine whether, and to what extent, perceived school climate (through the four CSCI dimensions – Safety, Relationships, Teaching Practices, and Institutional Environment) affects anxiety levels (measured via the DASS Anxiety Subscale) among secondary school students. The research was conducted at a medical secondary school in Skopje with a convenience sample of 100 students (30% male, 70% female). Participants were aged 16–19: 34% aged 16, 48% aged 17, 16% aged 18, and 2% aged 19. By grade, 56% were in second, 32% in third, and 12% in fourth year. Results confirmed the general hypothesis that a more positive school climate is associated with lower anxiety levels. The four sub-hypotheses were supported:H₁: Safety was moderately negatively correlated with anxiety (r = –0.39, p = .02). H₂: Positive relationships showed a moderate to strong negative correlation with anxiety (r = –0.385, p = .001).H₃: Teaching practices were weakly but significantly related to anxiety (r = –0.269, p = .006).H₄: Institutional environment demonstrated a moderate negative association with anxiety (r = –0.36, p = .008). Additionally, H₆ showed that perceived safety and relationships jointly and significantly predicted anxiety (R² = 0.863; p < .05). Demographic analyses indicated:H₇: Female students reported significantly higher anxiety levels than males (M=20.12 vs. M=10.31; p<.001).H₈: Anxiety increased with age (from M=11.35 at age 16 to M=24.68 at age 19; p<.001). H₉: Fourth-year students displayed higher anxiety (M=19.42) than second (M=11.67) and third-year (M=15.17) peers (p<.001). Qualitative insights from focus groups revealed an ambivalent perception of school – seen both as a place of friendship and as a “stressful enclosure” due to excessive testing and authoritarian teaching styles. Key stressors included oral examinations, public presentations, and perceived discrimination, while empathy from teachers and peer relationships provided moments of relief. Students’ recommendations focused on more interactive teaching, reduced testing load, stronger emotional support from psychologists, improved hygiene, and an inclusive culture of equality and respect. In conclusion, school climate and demographic factors (gender, age, grade) are significantly associated with students’ psychological well-being. To effectively reduce anxiety, interventions should integrate: Methodological innovations – interactive, motivating teaching practices; Emotional and social support – empathetic relationships, open communication with staff, psychologists, and peers; Institutional improvements – enhanced safety, hygiene, fair assessment, and inclusive culture. Implementing these measures can foster a safer, more supportive, and less stressful school environment, reducing anxiety symptoms and promoting overall student well-being.

In this work, we are interested in the long time behavior of a solution to equal mitosis partial differential equation with positive and periodic coefficients. First, we prove the existence and uniqueness of solution of Floquet eigenvalue and its adjoint eigenvalue problem to the equal mitosis equation by using the fixed point theorem in the suitable L1 weighted space under general division rate hypotheses. Let us recall that the Floquet exponent measures the growth rates of the population and understanding an eigenfunction is crucial for proving the long run behavior of the Cauchy problem. Then we apply the generalized relative entropy method to derive such long time asymptotic behavior of the population density.

Objective: Identify the relationship between professional competence and service efficiency in the Regional Directorate of Labor and Employment Promotion (DRTPE), Huanuco, 2023. Materials and methods: The research was of type the applied, approach quantitative, of level descriptive, and non-experimental design. The study sample consisted of 781 users that attended in the period of months of April to August 2023. Results: The correlation analysis evidenced a coefficient of 0.520, therefore there exists “positive media” relationship between the variables “professional performance” and “efficiency in services”; therefore, 44% of users stated that “almost never” the servers demonstrate knowledge of the assigned position, while a 22.4% indicated that “sometimes” they have the knowledge of the assigned functions, a 12.8% of respondents mentioned that “always”, a 11.2% mentioned that “never”, and 9.6% that “almost always”. Conclusions: Professional competence is significantly related to the efficiency of the service in the DRTPE, Huanuco, 2023. Thus, when applying the Pearson rho parametric test, the general hypothesis obtained a favorable result, from which it follows that there is a medium positive relationship between both variables.

Can language be a valuable predictor of genetic diversity even at the level of extremely circumscribed areas of linguistic diversity? We report on the analysis of mtDNA and NRY variation extracted from the whole-genome sequencing of 27 natives of Grecìa Salentina, a geographic area in southern Italy home to a historic Greek-speaking community. With respect to mtDNA, we found similarities with samples from Central Italy and Eastern Balkan, mainly because of the high haplogroups N, K and J1 frequencies. Detailed phylogeographic analyses of these haplogroups reveal instances of Grecìa Salentina-specific lineages. With respect to the NRY, we find similarities with other samples from southern Italy, Anatolia and the Middle East, because of the overwhelming frequency of haplogroup J2a. The new J2a lineages, many of which are specific to Grecìa Salentina, greatly expand the phylogeny of the haplogroup. Haplogroup R1a is also overrepresented, with a new lineage belonging to the GML6 subclade, which is common in the Western Balkans. All the above haplogroups were long recognized as markers of post-Neolithic East-to-West movements through the Balkan Peninsula by land or off its coasts by sea. We conclude that the peculiar component detected in the Grecìa Salentina gene pool is the result of past immigration. Specifically, there was a demic contribution of both sexes, which foreshadows the build-up of an entire community, and subsequent dilution in the surrounding gene pool by admixture occurred only to a limited extent. These results add a genomic dimension to our knowledge of the identity of the Greek-speaking community settled in Grecìa Salentina. To date, the peculiarity of the Grecìa Salentina population was only its linguistic identity, but we now show that it is also supported by a genetic component. The more general hypothesis of a connection between the demic and linguistic structure of the area can now be tested by comparing the genetics of Grecìa Salentina to those of other linguistic enclaves of Balkan origin in southern Italy.Supplementary InformationThe online version contains supplementary material available at 10.1038/s41598-025-31756-x.
