Spontaneous actions are preceded by brain signals that may sometimes be detected hundreds of milliseconds in advance of a subject's conscious intention to act. These signals have been claimed to reflect prior unconscious decisions, raising doubts about the causal role of conscious will. Murakami et al. (2014. Nat Neurosci 17: 1574–1582) have recently argued for a different interpretation. During a task in which rats spontaneously decided when to abort waiting, the authors recorded neurons in the secondary motor cortex. The neural (...) activity and relationship to action timing was parsimoniously explained using an integration-to-bound model, similar to those widely used to account for evidence-based decisions. In this model, the brain accumulates spontaneously occurring inputs voting for or against an action, but only commits to act once a certain threshold is crossed. The model explains how spontaneous decisions can be forecast (partially predicted) by neurons that reflect either the input or output of the integrator. It therefore presents an explicit hypothesis capable of rejecting the claim that such predictive signals imply unconscious decisions. We suggest that these results can inform the current debate on free will but must be considered with caution. (shrink)

Despite its recent popularity, Emergence is still a field where philosophers and physicists often talk past each other. In fact, while philosophical discussions focus mostly on ontological emergence, physical theory is inherently limited to the epistemological level and the impossibility of its conclusions to provide direct evidence for ontological claims is often underestimated. Nevertheless, the emergentist philosopher’s case against reductionist theories of how the different levels of reality are related to each other can still gain from the assessment of paradigmatic (...) examples of discontinuity between models in physics, even though their implications must be handled with care.

Enhancement is a basic principle of modern sport. Their increase of achievement is usually attributed to the sportsmen’s natural assessment, their health, their training methods and their employment. In contrast, increase in output by pharmacological means is outlawed. The modern medical techniques created a whole range, by which sportsmen are supported. Consequently, sometimes difficult decisions with concrete medications develop. It is not always clearly to be differentiated whether something is a pharmacological interference, which serves the therapy or leads however to (...) the outlawed increase in output. At present Enhancement is in discussion, a phenomenon, which is related to doping in sports, but which concerns achievement-increasing use of medicines not only in sportsmen. -/- Leistungssteigerung ist ein Grundprinzip des modernen Sports. Gewöhnlich werden für die Steigerung der Leistung die natürliche Veranlagung der Sportler, ihre Gesundheit, ihre Trainingsmethoden und ihr Einsatzwille veranschlagt. Leistungssteigerung durch pharmakologische Mittel ist dagegen geächtet. Die modernen medizinischen Techniken haben einen ganzen Bereich geschaffen, durch den die Sportler bei der Erbringung ihrer Leistung und deren Erhalt unterstützt werden. Dabei entstehen mitunter schwierige Entscheidungsfragen bei konkreten Medikationen. Nicht immer ist klar zu unterscheiden, ob etwas ein pharmakologischer Eingriff ist, der der Therapie dient oder aber zur geächteten Leistungssteigerung führt. Gegenwärtig wird über Enhancement diskutiert, ein Phänomen, das mit dem Doping verwandt ist, aber leistungssteigernde Verwendung von Medikamenten bei Gesunden im Allgemeinen, also nicht nur bei Sportlern, betrifft.

The ability to solve problems is a prerequisite in preparing mathematics preservice teachers. This study assessed preservice teachers’ problem-solving difficulties and performance, particularly in worded problems on number sense, measurement, geometry, algebra, and probability. Also, academic profile differences in the preservice teacher’s problem-solving performance and common errors were determined. A descriptive-comparative research design was employed with 158 random respondents. Data were gathered face-to-face during the first semester of the school year 2022-2023, and data were analyzed with the aid of jamovi (...) software, ensuring ethical measures. Overall findings revealed that the preservice teachers experienced average difficulty in solving problems. The low performance of the preservice teachers on the given problems was also demonstrated. Further analysis revealed a significant difference between the preservice teachers’ problem-solving performance based on their subject preference and program. Moreover, the error analysis revealed that the preservice teachers incurred comprehension errors in misrepresentation, misinterpretation, and miscalculation. These results will serve as a measure for policymakers and curriculum developers of the teacher education institution concerned to make relevant enhancements to the math courses offered in the elementary and secondary education programs.

This study investigates the significant relationship between mental health and academic motivation among graduating students. Thus, the study employed a correlational design to determine if there is a significant relationship between mental health and academic motivation among 150 graduating college students. Hence, the Mental Health Inventory 38 (MHI-38) and Academic Motivation Scale (AMS-C28) were employed to measure the study variables. Moreover, statistical analysis reveals that the r coefficient of 0.35 indicates a low positive correlation between the variables. The p-value of (...) 0.00, which is less than 0.05, leads to the decision to reject the null hypothesis. (shrink)

How does microbiota research impact our understanding of biological individuality? We summarize the interdisciplinary summer school on "Microbiota, Symbiosis and Individuality: Conceptual and Philosophical Issues" (July 2019), which was supported by a European Research Council starting grant project "Immunity, DEvelopment, and the Microbiota" (IDEM). The summer school centered around interdisciplinary group work on four facets of microbiota research: holobionts, individuality, causation, and human health. The conceptual discussion of cutting-edge empirical research provided new insights into microbiota and highlights the value of (...) incorporating into meetings experts from other disciplines, such as philosophy and history of science.

A number of experiences have demonstrated how digital solutions are effective in improving quality of life (QoL) and health outcomes for older adults. Smart Health Age-Friendly Environments (SHAFE) is a new concept introduced in Europe since 2017 that combines the concept of Age-Friendly Environments with Information Technologies, supported by health and community care to improve the health and disease management of older adults and during the life-course. This chapter aims to provide an initial overview of the experiences available not only (...) in Europe, based on the research work of the participants of the International Interdisciplinary Network on Health and Well-being in an Age-Friendly Digital World (NET4Age-Friendly), which could be of interest to preventive, health and social authorities. The chapter reports good practices, pain points, and bottlenecks that may require a collaborative, interdisciplinary research approach to facilitate the transformations towards smart, sustainable, health and age-friendly cities and communities.

This study examines the correlation between job descriptions and salaries at Immaculate Conception College of Balayan Inc. (ICCBI), a private Catholic institution devoted to faith-based education. Using qualitative research, a single-case study was conducted with ten (10) participants selected through purposive sampling based on specific criteria. Through face-to-face interviews, data was collected and analyzed using a narrative approach. Thus, it was found out that job descriptions at ICCBI are established through methods like job analysis, role and responsibility approaches, qualifications, and (...) the school manual-based method. Salary determination involves factors such as tenure, educational attainment, performance, teaching loads, experience, and collegial care. Key factors influencing job descriptions include salary differentiation, aligned job descriptions, career development opportunities, and increased duties and responsibilities. Variations in the salary structure are affected by teaching loads, department designations, and educational qualifications. The findings indicate that job descriptions impact employee salaries at the institution, and future research is encouraged to explore identified factors for insights into developing more efficient roles and contributing to organizational effectiveness. With this, the study proposed a strategic plan for future use and implementation. (shrink)

The article explores and discusses the doctoral research's creative, digital, and visual representation through the "RADICANT 003" virtual reality experience. Grounded in visual methods and the arts sciences, the article outlines its overall structure and contextualizes it within the broader research that in/forms it. It introduces Guma Joana, the Brazilian artist at the centre of this phase of the project. The article articulates theory and practice, ethnography and data presentation. And it is the experience we offer of the work (...) of the artist and of our own view of her that accounts for this dual operation. The paper details two digital mechanisms designed to engage users within the virtual reality environment: one mechanism deconstructs Instagram posts, while the other immerses the user in 360° videos.

This study examines the dynamics of queer expression in a neoliberal environment with Guma Joana and Amem Yhra, two cross-dressing artists from São Paulo. It explores how their Instagram profiles and participation in the Casa de Criadores event act as intermediary platforms between their informal creativity and the formal structures of creativity they aspire to integrate. Although these platforms allow visibility and promise social recognition, they also raise the question of how the resources from their lived experience are valued (...) and exploited, which can perpetuate forms of social dominance. The study is part of a reflection on the paradoxes of capitalist individualization, using visual semiotics in dialogue with philosophy and aesthetics. (shrink)
