Although the precise function of utrophin at the postsynaptic membrane of the neuromuscular junction still remains unclear, despite recent genetic ‘knockout’ experiments(1,2), a separate study in a transgenic mouse model system for Duchenne muscular dystrophy (DMD) has nonetheless shown that overexpression of utrophin into extrasynaptic regions of muscle fibers can functionally compensate for the lack of dystrophin and alleviate the muscle pathology(3). In this context, the next step is to identify the mechanisms presiding over expression of utrophin at the (...) neuromuscular synapse in attempts to induce its expression throughout DMD muscle fibers. In fact, additional studies have shown that an important DNA element contained with the utrophin promoter may confer synapse‐specific expression to the utrophin gene(4,5). Identification of the events culminating in the transaction of the utrophin gene within synaptic myonuclei should provide important cues for the development of an effective therapeutic strategy for DMD.

Aim: Participation in classroom physical activity breaks may improve children’s cognition, but few studies have involved adolescents. The primary aim of this study was to examine the effects of classroom-based resistance training with and without cognitive training on adolescents’ cognitive function.Methods: Participants were 97 secondary school students. Four-year 10 classes from one school were included in this four-arm cluster randomized controlled trial. Classes were randomly assigned to the following groups: sedentary control with no cognitive training, sedentary with cognitive training, resistance (...) training without cognitive training, and resistance training with cognitive training. Sessions varied in levels of both cognitive demand and resistance training and were administered three times per week for 4 weeks. Inhibition, cognitive flexibility, episodic memory, on-task behavior, and muscular fitness were assessed at baseline and post-test. Linear mixed models were used to examine changes within and between groups.Results: In comparison with the control group, episodic memory improved significantly in the resistance training without cognitive training group. There were no group-by-time effects for inhibition or cognitive flexibility. Classroom activity breaks both with and without cognitive demand improved participants’ on-task behavior in comparison with the control and sedentary group. The resistance training programs did not lead to improvements in muscular fitness.Conclusion: Participation in body weight resistance training without cognitive training led to selective improvements in episodic memory. No training effects were found for inhibition or cognitive flexibility. A longer study period may be necessary to induce improvements in muscular fitness and associated changes in inhibition and cognitive flexibility.Clinical Trial Registration:https://www.anzctr.org.au/ACTRN12621001341819.aspx, Australian New Zealand Clinical Trials Registry—ACTRN12621001341819.

Affectively uncomfortable concern, anxiety, indecisionand disputation over ‘right’ action are among the expressions of moral tension associated with ethical dilemmas. Moral tension is generated and experienced by people. While ethical principles, rules and situations must be worked through in any dilemma, each occurs against a backdrop of people who enact them and stand much to gain or lose depending on how they are applied and resolved. This paper attempts to develop a taxonomy of moral tension based on (...) its intrapersonal and interpersonal sources and expressions. The proposed ‘ethics of incongruity’ outlines ways in which values, actions and needs can find themselves mismatched in morally relevant ways between patients and their clinicians, their own psychologies and their societies. Patient–clinician incongruities may manifest as discord, value misalignment and deception. Patient–patient incongruities may manifest as incapacity, akrasia and self-deception. Patient–society incongruities may manifest as disenfranchisement, disaffiliation and disregard. Brief explanations of the incongruities in this scheme are provided, as are suggestions on working within them. Using concepts from moral philosophy when applicable, these suggestions may either ease direct resolution of problems arising from the incongruities, or make sense of the moral tension that arises from the human context of the ethical dilemma at hand. This presentation of content and resolution methods for the EOI is no doubt incomplete. Hopefully, refinement of this preliminary proposal will follow, particularly from clinicians, as the ones who, along with their patients, experience medical ethics in directly tension-inducing ways.

There is an alleged tension between undue inducement and exploitation in research trials. This paper considers claims that increasing the benefits to research subjects enrolled in international, externally-sponsored clinical trials should be avoided on the grounds that it may result in the undue inducement of research subjects. This article contributes to the debate about exploitation versus undue inducement by introducing an analysis of the available empirical research into research participants' motivations and the influence of payments on research subjects' behaviour (...) and risk assessment. Admittedly, the available research in this field is limited, but the research that has been conducted suggests that financial rewards do not distort research subjects' behaviour or blind them to the risks involved with research. Therefore, I conclude that research sponsors should prioritise the prevention of exploitation in international research by providing greater benefits to research participants. (edited). (shrink)

The increasing significance of inter- and transdisciplinary research raises the demand for principles with respect to methodology and philosophy of science. The discussion of this question leads to the development of an interdisciplinary research process with two methodic core areas: system integration and inducement of innovation. It will be shown that interdisciplinary research can be understood as a discipline of its own, while its potential of synthesis cannot be declared as a central distinctive feature relative to other disciplines. In fact (...) the developed methodology is firstly aligned analytically, with a focus on the research potential from the area of tension between individual disciplines. This results in an interdisciplinary methodology, generating epistemological progress, which can be applied to complex and cooperation intensive research in academia as well as industry and society.

According to virtue epistemology, the main aim of education is the development of the cognitive character of students (Pritchard, 2014, 2016). Given the proliferation of technological tools such as ChatGPT and other LLMs for solving cognitive tasks, how should educational practices incorporate the use of such tools without undermining the cognitive character of students? Pritchard (2014, 2016) argues that it is possible to properly solve this ‘technology-education tension’ (TET) by combining the virtue epistemology framework with the theory of extended (...) cognition (EXT) (Clark and Chalmers, 1998). He argues that EXT enables us to consider tools as constitutive parts of the students’ cognitive system, thus preserving their cognitive character from technologically induced cognitive diminishment. The first aim of this paper is to show that this solution is not sufficient to solve the TET. Second, I aim to offer a complementary and more encompassing framework of tool-use to address the TET. Then, I apply it to the educational uses of ChatGPT as the most notable example of LLM, although my arguments can be extended to other generative AI systems. To do so, in Sect. 1.1, I present Pritchard’s framework of cognitive character and virtue epistemology applied in education, to which I am committed in this treatment. In Sects. 2 and 3, I respectively illustrate Pritchard’s (2014) solution to the TET, and I highlight the general limitations of his proposal. Thus, in Sect. 4.1 I characterize ChatGPT as a computational cognitive artifact using Fasoli’s (2017, 2018) taxonomy of cognitive artifacts. In Sect. 4.2, I introduce my proposal, which combines Pritchard’s account of virtue epistemology with Fasoli’s (2017, 2018) taxonomy of cognitive artifacts to address the TET. Finally, in Sect. 5.1, I present some epistemically virtuous uses of ChatGPT in educational contexts. To conclude, I argue in favor of a multidisciplinary approach for analyzing educational activities involving AI technologies such as ChatGPT. (shrink)

Die zunehmende Bedeutung inter-und transdisziplinärer Forschungsfelder wirft die Frage nach entsprechenden methodischen und wissenschaftstheoretischen Grundlagen auf. Die Auseinandersetzung mit dieser Frage führt hier zur Entwicklung eines interdisziplinären Forschungsablaufes mit zwei methodischen Kernbereichen, die Systemintegration und Innovationsgenese. Eine wissenschaftstheoretische Betrachtung zeigt auf, dass sich die interdisziplinäre Forschung selbst als eigenständige Disziplin begreifen lässt, und ihr Synthesepotential nicht als zentrales Unterscheidungsmerkmal zu anderen Disziplinen angesehen werden kann. Vielmehr ist die hier entwickelte Methodologie zunächst analytisch und im Wesentlichen auf die Erschließung des Forschungspotentials (...) im Spannungsfeld der Einzel Wissenschaften ausgerichtet. Es entsteht somit eine erkenntnisleitende interdisziplinäre Methodologie, die sich auf komplexe bzw. kooperationsintensive Forschungsinhalte, sowohl im akademischen Bereich als auch auf Fragestellungen aus Industrie und Gesellschaft, anwenden lässt.
