Normal aging is typically associated with declines in navigation and spatial memory abilities. However, increased interindividual variability in performance across various navigation/spatial memory tasks is also evident with advancing age. In this review paper, we shed the spotlight on those older individuals who exhibit exceptional, sometimes even youth-like navigational/spatial memory abilities. Importantly, we (1) showcase observations from existing studies that demonstrate superior navigation/spatial memory performance in late adulthood, (2) explore possible cognitive correlates and neurophysiological mechanisms underlying these preserved spatial abilities, (...) and (3) discuss the potential link between the superior navigators in late adulthood and SuperAgers (older adults with superior episodic memory). In the closing section, given the lack of studies that directly focus on this subpopulation, we highlight several important directions that future studies could look into to better understand the cognitive characteristics of older superior navigators and the factors enabling such successful cognitive aging.

While old age is typically associated with a decline in spatial memory and navigational abilities,a subset of older adults demonstrates superior, sometimes even youth‐like performance. Here, we review cognitive and neural factors contributing to such superior spatial abilities, and we discuss potential links with preserved episodic memory in SuperAgers.

This essay seeks to shed light on the connections between elevated isnād and al-sābiq wa’l-lāhiq (distance between the first and last narrator of traditionist). Since the 2nd/8th century, when the search for elevated isnāds began, intense interest has been seen by the traditionists. The article looks at how these initiatives to elevated isnād helped pave the way for the emergence of al-sābiq wa’l-lāhiq. Similarly, it is investigated if al-sābiq wa’l-lāhiq promotes the look for elevated isnād. First, the data documentation approach (...) was applied to data taken from the history of hadith, various hadith techniques, and biographical dictionaries to ascertain the relationship between two notions. The relationship between two themes is then made clear using information from Khatīb Baghdādī’s (d. 463/1071) al-Sābiq wa’l-lāhiq, the first work authored in this field. Significance of the study of Khatīb Baghdādī’s work is further increased by the fact that he was the first to present the idea. The relationship between the subjects has been looked at in the article from three different theoretical angles. First, historical information has been used to assess how the orientation of hadiths concerning elevated isnād created the stage for the conception of al-sābiq wa’l-lāhiq. Then, the connection between subjects was examined through explanations of hadith methodology and biographical dictionaries authors. When the historical records of hadiths are reviewed, it becomes clear that the traditionist supported the hearing of elevated isnād and its transmission starting in the 2nd/8th century, particularly in the 3rd/9th and 4th/10th centuries. al-Sābiq wa’l-lāhiq was founded as a consequence of factors including the existence of grandfathers and grandchildren who reported from a single hadith due to orientation in elevated isnād and the fact that certain traditionists took pride in passing down the narrations of the elders to the younger generations. In addition, as the century moved away from the Prophet, the elevated isnāds that enable to reach him with a short isnād gained more importance. This situation explains why al-sābiq wa’l-lāhiq was formed in the 5th/11th century. It was also discovered that Khatīb Baghdādī’s introduction of this idea to the discussion was not a coincidence, and it was stated that this was due to his interest in elevated isnād. The connection established by the authors of hadith methodology between two concepts is that al-sābiq wa’l-lāhiq encourages the audition of elevated isnād. al-Lāhiq in other words hadith aspirants who want to be the last person who transmits hadith from a traditionist, that is, turning to mu‘ammerūn (long-lived) teachers at a young age supports the audition of elevated isnād. The efforts of biographical dictionaries authors to record elevated isnads that reached al-lāhiq were evaluated as a different manifestation of this situation. The connection between two subjects has also been examined in the work of Khatīb Baghdādī, which has the same name as the concept and various findings were obtained about al-sābiq wa’l-lāhiq and traditionists who were attributed to him as al-sābiq wa’l-lāhiq. According to this, it has been understood that traditionists who were compared to al-sābiq wa’l-lāhiq were chosen from among the long-lived people. A study was conducted on 6 traditionists, in whom Khatīb determined the ratio of al-sābiq wa’l-lāhiq to 10 or more. According to this, it has been determined that the narrators, who are mentioned as al-sābiq, are generally attributed to teachers or peers of traditionists. However, it has been revealed that there is no obligation to be a teacher or peer, and sometimes there are al-sābiqs among the students. The fact that most of the al-sābiqs are teachers and peers shows that the concept is considered a rarity. Because in the history of hadith, isnād generally goes from student to teacher. In addition, the narration of peers from each other or the teacher from students showed that narrators, who are called al-sābiq, have descending isnāds from that teacher. However, it has been determined that not all the narrations of al-sābiq were descending, only of whose narrations from that traditionist would be regarded as descending. As al-lāhiq, on the other hand, is the last person to transmit hadith from traditionist, he already has elevated isnād and all of them are long-lived people. However, the missing part of Khatīb’s book is that he does not pay attention to whether al-lāhiq is reliable or abandoned. In addition, it was stated that al-lāhiq should be chosen only from reliable, and in this case, it would not affect the distance between al-sābiq and al-lāhiq. (shrink)

We consider situations of multiple referendum: finitely many yes-or-no issues have to be socially assessed from a set of approval ballots, where voters approve as many issues as they want. Each approval ballot is extended to a complete preorder over the set of outcomes by means of a preference extension. We characterize, under a mild richness condition, the largest domain of top-consistent and separable preference extensions for which issue-wise majority voting is Pareto efficient, i.e., always yields out a Pareto-optimal outcome. (...) Top-consistency means that voters’ ballots are their unique most preferred outcome. It appears that the size of this domain becomes negligible relative to the size of the full domain as the number of issues increases. (shrink)

Perceived uncertainty and anger lead people to investigate with respect to the establishment, and politicians who are seen as reckless within society. In this sense, populist discourse paved a way to respond by glorifying one group of people and scapegoating others that emerge as group differentiation. Critical moments especially illustrate mutual constructive identification through the discourse of political actors. This article explores a contextual change in the populist discourse of the Justice and Development Party leaders by observing the successive elections (...) that occurred in 2015. It argues that the leaders mainly expressed an “us–them distinction,” “in-group superiority,” and “the people” populist themes; as well as these themes, the electoral speeches made for the second election presented scapegoating and exclusionary statements even more.

The Philosophical Ethics in Early Childhood project aims to advance knowledge of preschool children’s ethical understanding and explores the effectiveness of philosophical discussion of children’s literature and extension activities for fostering ethical development in early childhood. In this article we discuss results of our ethics education study with preschool children, including pre-post measurement of experimental and control groups and a 12-week educational intervention focusing on the themes of fairness, empathy, personal welfare and inclusion versus exclusion of peers. As compared to (...) our control group, study results demonstrated significant developments in our experimental group’s ability to respond to ethical questions, increased use of emotion markers, and increased use of justification terms in support of responses.

In this article, in an attempt to analyze the crisis caused by the images of imported plastic waste, we consider the relationship between waste and its meaning in the case of geographical dislocation and de- and re-contextualization processes. Our analysis is guided by two recent concepts: The Wasteocene and semiocide. While the Wasteocene clarifies the signifying mechanisms of this period, semiocide allows us to understand which signs, under what conditions, are rendered invisible or disregardable. In coining the concept of semiocide, (...) Ivar Puura emphasized two key features of the phenomenon. Following this distinction, which is based on (un)intentionality, semiocide refers either to a fully conscious, perhaps even hostile, attempt to destroy a semiotic configuration, or to a completely nonconscious, unaware process in which the unawareness itself is the source of the destruction. Although a more cultural approach dominates in Puura’s assertion of the concept, the concept is applicable to human classification, interpretation and transformation of nature (Maran, 2013; Tønnessen et al., 2015). Focusing on the case of Adana as a recent example of a global waste crisis, our aim is to provide a (bio)semiotic framework for assessing how and under what conditions plastic materials become arbiters of environmental and political crises. With heaps of plastic garbage with foreign names on them, the discourse of recycling, restricted media coverage, public indignation, the struggles of environmentalist organizations, and the encounter of different spatio-temporalities, our study aims to convey an impoverished narrative of a city in the south of Türkiye.

During the seventies, the Belgian-Zairese relations are characterized by a series of crises and reconciliations.Many facts had an important effect on those relations : the « Zairianisation » of foreign, especially Belgian, companies; President Mobutu's request for economic aid; the Shaba-invasion of 1977; the presence of Zaïrese opponents in Belgium and the hostility against Kinshasa and especially against President Mobutu from the part of particular Belgian circles.All these facts make it very difficult to Belgium to draw a coherent policy in (...) this case.

Le pendule de Foucault a exercé sur les savants belges une fascination durable. Dès 1852, l’expérience de Foucault suscite l’intérêt de Schaar, Pagani et Gilbert. À la suite des travaux de Mach, Duhamel, Poincaré, Duhem et d’autres mathématiciens, physiciens et philosophes, les publications de la Société scientifique de Bruxelles abritent de vives discussions sur les notions d’espace et de mouvement absolus, entre les savants belges De Tilly, Mansion et Pasquier et leurs collègues français Vicaire et Lechalas. Le cinquantième anniversaire de (...) l’expérience de Foucault est l’occasion d’une polémique entre Anspach et Pasquier, ce dernier défendant les idées de Poincaré. Au vingtième siècle, les études de Janne d’Othée et Bouny sur le pendule de Foucault montrent qu’ils sont définitivement acquis aux idées de Poincaré.Foucault’s pendulum has long fascinated Belgian scientists. From 1852 onward, the Foucault experiment attracted the interest of Schaar, Pagani and Gilbert. Following the work of Mach, Duhamel, Poincaré, Duhem and other mathematicians, physicists and philosophers, the publications of the Société scientifique de Bruxelles contain lively discussions of the concepts of absolute space and motion between the Belgian scientists De Tilly, Mansion, Pasquier and their French colleagues Vicaire and Lechalas. The fiftieth anniversary of Foucault’s experiment is the source of a polemic between Anspach and Pasquier, the latter defending Poincaré’s ideas against the former. In the twentieth century, the studies of Janne d’Othée and Bouny about Foucault’s pendulum show that Poincaré’s thesis has been fully adopted. (shrink)

By the law of the 8 August 1980 concerning the institutional reform of the state, the Belgian political system is becoming a federalistic country. Nevertheless, after three years of implementation, most of political scientists state that these constitutional reform is incomplete and inadequate to solve functionally the economical, political and cultural complexities of the relationships between Flanders, W allonia and Brussels. A confederation based on three components equally autonomous by preserving economic integration and monetary unity could be a better framework (...) to establish equitable relationships between the three regional components of the belgian political structure. These proposal of creating a Belgian confederation presents specific adaptations in allocation tasks, functions and competences that are the results of historical factorsand cultural caracteristics of the Belgian community.

In French-speaking Belgium, the educational system is made particular and complex because of the presence of several educational networks. This structural complexity leads, in particular, to provide multiple programs studies which are used by teachers for the preparation of teaching-learning sequences. Using data from several studies on the analysis of a part of the prescribed and implanted curriculum, the authors point out the complexity of teachers’ task who have to take into account of this plurality of programs studies. Here, it’s (...) shown that this situation is far from generating well-being and self-determination in the professional development of teachers. (shrink)
