Background: The vascular depression hypothesis emphasizes the significance of vascular lesions in late-life depression. At present, no meta-analytic model has investigated whether a difference in hyperintensity burden compared to controls between late-life and late-onset depression is evident. By including a substantial number of studies, focusing on a meaningful outcome measure, and considering several moderating and control variables, the present meta-analysis investigates the severity of hyperintensity burden in major depressive disorder (MDD) and bipolar disorder (BD). A major focus of the present (...) meta-analysis refers to the role of age at illness onset. It is analyzed whether late-onset rather than late-life depression characterizes vascular depression. Method: In total, 68 studies were included in the meta-analysis and a multilevel random effects model was calculated using Hedges’ g as the effect size measure. Results: The severity of hyperintensity burden was significantly greater in the patient group compared to the control group. This effect was evident regarding the whole patient group (g = 0.229) as well as both depression subgroups, with a significantly greater effect in BD (g = 0.374) compared to MDD (g = 0.189). Hyperintensity burden was more pronounced in late-onset depression than in early-onset depression or late-life depression. A considerable heterogeneity between the included studies was observed, which is reflected by the large variability in effects sizes. Conclusion: In conclusion, the present meta-analysis underscores the association of hyperintensities with MDD and BD. Especially late-onset depression is associated with an increased hyperintensity burden, which is in line with the vascular depression hypothesis. The results suggest that it might be more feasible to confine the concept of vascular depression specifically to late-onset depression as opposed to late-life depression. Further research is needed to understand the causal mechanisms that might underlie the relation between hyperintensity burden and depression. (shrink)

The great powers of regeneration shown by freshwater planarians, capable of regenerating a complete organism from any tiny body fragment, have attracted the interest of scientists throughout history. In 1814, Dalyell concluded that planarians could “almost be called immortal under the edge of the knife”. Equally impressive is the developmental plasticity of these platyhelminthes, including continuous growth and fission (asexual reproduction) in well‐fed organisms, and shrinkage (degrowth) during prolonged starvation. The source of their morphological plasticity and regenerative capability is a (...) stable population of totipotent stem cells—“neoblasts”; this is the only cell type in the adult that has mitotic activity and differentiates into all cell types. This cellular feature is unique to planarians in the Bilateria clade. Over the last fifteen years, molecular studies have begun to reveal the role of developmental genes in regeneration, although it would be premature to propose a molecular model for planarian regeneration. Genomic and proteomic data are essential in answering some of the fundamental questions concerning this remarkable morphological plasticity. Such information should also pave the way to understanding the genetic pathways associated with metazoan somatic stem‐cell regulation and pattern formation.

This book explores the puzzling phenomenon of new veiling practices among lower middle class women in Cairo, Egypt.

Ausgehend von einer Bestimmung der ästhetischen Erfahrung als Erfahrung der Art und Weise der sinnlichen Gegebenheit von Gegenständen und Umwelten geht der vorliegende Text der Frage nach den Spezifika alltagsästhetischen Erfahrens nach. Dabei wird zunächst die alltagsästhetische Einstellung als eine fest in den handelnden Vollzug gewohnter Praktiken und Routinen eingebettete Wahrnehmungshaltung bestimmt. In einem nächsten Schritt werden charakteristische Merkmale alltagsästhetischen Erfahrens herausgearbeitet: Zu nennen sind die Wahrnehmung von – theoretisch näher zu beschreibenden – Ganzheiten, die Kategorien des Vertrauten, des Rhythmus (...) und des Takts sowie schließlich das Zusammenspiel aller Sinne. Die abschließenden Überlegungen widmen sich der engen Verbindung von moralischen, ästhetischen und funktionalen Erfahrungen und Urteilen im Raum des Alltäglichen. (shrink)

In recent years, global corporations and national governments have been enacting a growing number of codes of conduct and public regulations to combat dangerous and degrading work conditions in global supply chains. At the receiving end of this activity, local producers must contend with multiple regulatory regimes, but it is unclear how these regimes interact and what results, if any, they produce. This article examines this dynamic in the sugar sector in Brazil. It finds that although private and public agents (...) rarely communicate, let alone coordinate with one another, they nevertheless reinforce each other’s actions. Public regulators use their legal powers to outlaw extreme forms of outsourcing. Private auditors use the trust they command as company insiders to instigate a process of workplace transformation that facilitates compliance. Together, their parallel actions block the low road and guide targeted firms to a higher road in which improved labor standards are not only possible but even desirable. (shrink)

Le sceptique nous demande " Comment sais-tu que tu as deux mains? Peut-être rêves-tu, ou es-tu trompé par quelque Malin Génie? Peut-on même définir ce que c'est que la connaissance? Va savoir! " Lui rétorquer, comme le faisaient G.E. Moore et la tradition de la philosophie du sens commun : " Mais je sais bien que j'ai deux mains! " semble à la fois une pétition de principe et une bien mauvaise réponse. Le mieux, depuis que nous avons perdu le (...) souci de fonder nos croyance sur des raisons ultimes, serait, tout simplement, de ne pas se soucier des questions du sceptique. Ce que l'on sait dépend, nous dit-on, des circonstances, et toutes nos connaissances sont faillibles. N'y a-t-il pas plutôt des savoirs, dont l'histoire nous montre combien leurs modes de validations sont variés? Ce livre entend refuser ce type de réponse contextualiste et relativiste. Il propose de revenir à la réponse de sens commun de Moore, à partir des reformulations contemporaines des raisonnements sceptiques issues de la philosophie analytique de la connaissance. Personne ne peut nous envoyer savoir quelque chose que nous ne pourrions pas savoir. De fait, nous savons, mais notre savoir n'est pas transparent : nous n'avons pas besoin de savoir que nous savons. Pour parvenir à cette réponse, il faut replacer la notion de connaissance, plutôt que celle de croyance justifiée ou rationnelle, au centre de l'épistémologie, et reformuler des questions traditionnelles comme celles de la nature de la perception, du témoignage, et de la connaissance a priori. On peut aussi reprendre le vieux projet d'une enquête sur la nature de la connaissance en général. (shrink)

Mothers with prenatal substance use disorder often show broad deficits in their reflective functioning, implying severe risk for the relationship with their baby. Two different types of prenatal maternal RF may be important for parenting: adult attachment-focused-RF, regarding parent's own childhood experiences, and parenting-focused RF regarding their own current process of becoming a parent. However, their inter-relations and potentially different roles for parenting intervention outcomes are not clear. This study examined the associations between mothers' prenatal AAI-RF and pre- and post-natal (...) PRF, and their role in mother-infant interaction and substance use as treatment outcomes. The participants were 57 treatment-enrolled pregnant mothers with SUD and 50 low-risk comparison mothers. AAI-RF was measured with the Adult Attachment Interview. For a subsample of 30 mothers with SUD, PRF was measured with Pregnancy Interview, and with Parent Development Interview at 4 months. Mother-infant interaction was measured with Emotional Availability Scales at 4 and 12 months, and maternal substance use by post-natal substance relapses. Prenatal AAI-RF and pre- and post-natal PRF were highly associated with each other. Only higher prenatal PRF predicted better mother-infant interaction quality at 4 months and less substance use during the child's first year. Interestingly, prenatal PRF and AAI-RF predicted opposite changes in mother-infant interaction: lower prenatal PRF, but higher AAI-RF predicting more positive change. AAI-RF was especially associated with a change in maternal intrusiveness and hostility, indicating that it represents a more general regulatory tendency. Further studies are needed in larger and lower-risk samples. Our results suggest, however, that AAI-RF and PRF are partially distinct and should be uniquely targeted in perinatal interventions.

Zusammenfassung: Obwohl sich die „Philosophie der Stadt“ in den letzten Jahrzehnten dynamisch entwickelt hat, stellt sie noch keine klar konturierte philosophische Teildisziplin dar. Dieser Zustand birgt Chancen und Probleme: Die aktuellen Debatten sind vielschichtig und kreativ, die Potentiale verschiedener Theorien, Traditionen und Methoden zur philosophischen Erschließung der Stadt werden erprobt und kombiniert. Zugleich zeigt sich nach wie vor eine gewisse Unsicherheit hinsichtlich der genauen Ziele und Aufgaben einer Philosophie der Stadt sowie hinsichtlich ihres Verhältnisses zu anderen Disziplinen der Stadtforschung. Die (...) Einleitung in den Schwerpunkt gibt Einblicke in den Stand der Debatte, arbeitet auf dieser Basis drei Ansätze der Beschreibung der Ziele und Aufgaben einer Philosophie der Stadt heraus, und ordnet die Beiträge des Schwerpunktes in diese Systematik ein.

Since the introduction of Ethereum in 2015, blockchain technology (BT) has been evolving, and BT has been associated with the concept of the sharing economy by business academics. Despite the marketing research on the sharing economy that has been extensively conducted in the last decade, the linkage between BT and ethical marketing in the sharing economy remains unclear. Through a systematic literature review of 163 articles and a co-citation analysis, this study identifies the key elements of blockchain capabilities, blockchain attributes, (...) and the underlying economic theories of blockchain. It also synthesizes and proposes a shift of ethical marketing logic in the blockchain-based sharing economy that delineates the principles of stakeholder capitalism. The article concludes with a list of future research directions that underline three approaches of stakeholder theory (i.e., the descriptive, instrument, and normative approaches). These directions aim to guide marketing scholars concerning how BT enables an institutionally embedded view of ethical marketing activities and practices that enhance collaborative marketing and subsequently innovate value chains and create sustainable business models in the sharing economy, as well as to the metaverse.

The failures of a philosophic system are often a good deal more revealing than its successes, for such failures test its strength and mark the limits of its endurance. Yet if these failures disclose any uniform pattern they are not only revealing but instructive and can be turned to good account.
