مستخلص: Objectives: To address global aging, a paradigm shift is needed from disease prevention and treatment towards active aging, i.e., optimizing opportunities for health, participation, and security as people age. Little is known about how age-friendly environments promote active aging. This study thus aimed to explore how (through which mechanismsand in what contexts) environments can promote active aging and, specifically, positive health, social participation, and health equity. Methods: Using a realist approach and semi-structured focus groups, a case study was used in two Quebec municipalities known for best fostering active aging. Data also included participants’ logbooks, sociodemographic questionnaires, municipalities’ sociodemographic profiles, and policy documents. A conceptual framework and thematic content analysis were carried out. Results: A total of 24 participants (9 older adults, 4 health professionals, 3 community-based actors, 5 municipal employees, and 3 elected officials) took part in 5 focus groups. Regarding contexts, both cases were midsize municipalities having an income and education level higher to Quebec’s averages with supportive active aging policies. Two main themes explained how the environments promoted active aging: (1) by ensuring proximitythrough built (urban planning), social (network structures), services (variety and availability of local and outreach resources), and organizational (active listening to older adults’ needs for active aging) environments; and (2) by fostering transversalitythrough built (universal accessibility, intergenerational spaces), social (intergenerational opportunities for social participation), and political/organizational (unified and complementary policies) environments. Conclusion: To better promote active aging through age-friendly environments, practices should focus on fostering proximity and transversality, and act simultaneously on multiple environments.

مستخلص: The article focuses on the unsolved murder of Frank J. Robinson a civil rights leader and voting rights advocate in East Texas in the 1970s. Topics include his successful challenge of gerrymandering of black voters in East Texas, his plans to empower black voters in surrounding counties, and his mysterious death which was determined to be a homicide.

مستخلص: Unattachment to a regular primary care professional can affect children’s and adolescents’ well-being, considering their unique health needs. Having no alternative, many turn to emergency departments for non-urgent conditions. To help unattached patients access healthcare services while on waitlists, Quebec’s government implemented single access points in each administrative region across the province. Our study aimed to describe the paediatric population using single access points and identify associations between their characteristics and need for a medical appointment. Clinical-administrative data of 1,323 paediatric access point users in the Montérégie region from November 2022 to March 2023 were utilized to conduct bivariate and multivariable regression analyses. Our study showed that young age, assessment trajectory, and specific reasons for calling were more likely to necessitate a medical appointment. While access points improve accessibility to doctors, questions remain regarding the relevance of medical consultations, inequities, and possible security issues resulting from the overall process.

مستخلص: Mammalian sperm are stored in the epididymis in a dormant state. Upon ejaculation, they must immediately start producing sufficient energy to maintain motility and support capacitation. While this increased energy demand during capacitation is well established, it remains unclear how mouse sperm modify their metabolism to meet this need. We now show that capacitating mouse sperm enhance glucose uptake, identifying glucose uptake as a functional marker of capacitation. Using an extracellular flux analyzer, we show that glycolysis and oxidative phosphorylation increase during capacitation. Furthermore, this increase in oxidative phosphorylation is dependent on glycolysis, providing experimental evidence for a link between glycolysis and oxidative phosphorylation in mouse sperm.

مستخلص: The German energy transition towards more sustainable forms of energy production has been characterized as a large-scale or real-world experiment. Whereas experiments are open-ended processes set up explicitly to allow (or even generate) surprises, by contrast sustainability implies the pursuit of clearly defined, normative ends. Whereas much of the literature on system transformation builds on the concept of innovation, our hypothesis is that focusing on the “natural” flipside of innovation—called here “exnovation,” i.e., departing from unsustainable pathways—should also be seen as a valuable conceptual strategy for coping with the tension between the unavoidable indeterminacy resulting from unknown risks and the necessary amendment and redefinition of goals and rules. In this paper the German energy transition (Energiewende) is used to exemplify the recursive processes of experimentation that make it possible to accommodate surprise, and, thus, to conceptualize the unavoidable tension between innovation and the maintenance of older, unsustainable structures.

مستخلص: Scholars looking at policy mixes for the energy transition and seeking to facilitate a move away from fossil-based structures are increasingly addressing the opposite side of innovation. To describe this, the article introduces the concept of exnovation, referring to attempts to end fossil-based technological trajectories in a deliberate fashion. It applies a framework that encompasses innovation and exnovation alike in order to investigate the policy mix of the German energy transition. Beside finding that energy transition policy mixes need to emphasize regulatory instruments more in order to bring about decarbonization, the article also describes some general aspects of the policy mix design required to govern the innovation-exnovation nexus.

مستخلص: Die hohe gesellschaftliche und politische Relevanz der Rohstoffgewinnung wird in Zukunft eher zu- als abnehmen. Umso wichtiger ist es, den Kreis derer, die zum Rohstoffsektor und seinen Implikationen forschen, auf andere Akteure und Disziplinen auszuweiten. Sonst dominieren weiterhin technische und naturwissenschaftliche Zugänge. [ABSTRACT FROM AUTHOR]

مستخلص: Recent events in world politics, from the implosion of Syria and the Ukraine to China’s growing assertiveness in the East and South China Seas, have exposed the limitations of the dominant idealist and normativist paradigms in the study of international relations. In a world that is more Metternich than Rawls, it is necessary once again to examine statecraft from a realist perspective and to focus on the reasons of state that have informed its practice since the sixteenth century. Attention, here, is also focused on the rhetoric that informed political counsel and how a form of prudential reasoning shaped the art of diplomacy. In this context, casuistry, which involved applying principles of case law in particular circumstances, offered a mode of practical reasoning very different from contemporary normative approaches whose rhetoric seems increasingly divorced from the real practice of power and interest. Casuistry can be seen, as Stephen Toulmin has argued, as a form of situational or practical ethics. Casuistry, prudence and a particularist ethical practice might offer a more illuminating way of interpreting our increasingly complicated, interconnected but by no means integrated world.
