Die Erforschung der Zusammenhänge zwischen Gehirnplastizität und individuellem Verhalten gestaltet sich aufgrund ihrer Komplexität im Tiermodell schwierig. Die vorliegende Studie wurde im mit dem Ziel konzipiert, die Individualitätsentwicklung bei Mäusen mit den gleichen physiologischen und genetischen Voraussetzungen in einer komplexen räumlichen und sozialen Umgebung zu beschreiben. Ich untersuchte die Korrelation dieser Entwicklung mit der Neurogenese im adulten Hippokampus als Maß für Gehirnplastizität. Zu diesem Zweck wurden zwei je mit einem automatisierten RFID-Tracking-System ausgestattete Großgehege mit jeweils 40 Tieren besiedelt. Die Bewegungen der Tiere wurden kontinuierlich aufgezeichnet und es wurden zudem direkte Verhaltensbeobachtungen durchgeführt. Die Tiere zeigten eine normale physiologische Entwicklung. Die Roaming Entropy (RE), ein Maß für die Gleichmäßigkeit, mit der die Tiere ihr Gehege nutzten, beschreibt das Erkundungsverhalten der einzelnen Mäuse. Die kumulativ erworbenen RE-Werte (cRE) in jedem der beiden Gehege wurden mit der Zeit zunehmend verschieden. Es war nicht möglich, aufgrund kleiner anfänglicher Unterschiede die Endwerte zu berechnen. Das bedeutet, dass die Tiere erst durch die andauernde Interaktion mit ihrer Umwelt und den Artgenossen unterschiedlicher wurden. Darüber hinaus sind die cRE-Werte am Endpunkt positiv mit den Neurogenesewerten korreliert. Dies beweist, dass während der Entwicklung auftretende Faktoren die Individualitätsentwicklung beeinflussen. Dieser Prozess benötigt plastische Hirnstrukturen und formt diese wiederum. Die Verhaltensanalysen zeigten, dass Tiere, die viele Antennenkontakte sammelten („most active“, MA) nicht zwangsläufig auch hohe cRE-Werte hatten. MA-Mäuse waren häufiger an sozialen Interaktionen beteiligt als Tiere mit wenigen Antennenkontakten („least active“, LA), akkumulierten über die Zeit niedrigere cRE-Werte und standen vermutlich weiter unten in der sozialen Hierarchie. Zusammenfassend kann man sagen, dass das Ausmaß der räumlichen Exploration und die allmähliche Erweiterung der Erfahrung mit einer gesteigerten Plastizität des Gehirns in Form von adulter Neurogenese verbunden war. Die Daten zeigen, dass Tiere mit den gleichen Voraussetzungen sich dennoch auf zunehmend divergierende, individuelle Art entwickeln. Dies ist zumindest teilweise durch leicht unterschiedliche epigenetische Voraussetzungen zu erklären, die durch das Wechselspiel mit dem komplexen Umfeld weiter auseinanderdriften. Auch scheint es, dass Individuation lebenden Organismen inhärent und Voraussetzung für evolutionäre Prozesse ist. Die Studie zeigt, dass die Unterschiede in individuellem Verhalten und Gehirnstruktur nicht allein durch Genen und Umweltbedingungen festgelegt sind, sondern auch durch Faktoren, die sich während der ontogenetischen Entwicklung entfalten, beeinflusst werden. Der beschriebene Versuchsaufbau stellt darüber hinaus ein Tiermodell für die Untersuchung von Mechanismen und modulierenden Faktoren auf die strukturellen Grundlagen der Plastizität als individuelle Reaktion auf die gemeinsam genutzte Umgebung dar. / The complex nature of the relationship between brain plasticity and individual behaviour renders its investigation using animal models difficult. The present study was designed to describe the emergence of individuality in mice with the same physiological, environmental and genetic preconditions in response to complex environmental and social cues. I investigated the correlation of this development to brain plasticity, namely neurogenesis in the adult hippocampus. To this end, two large, multi-level enclosures fitted with and automated RFID tracking system were populated with 40 animals to each. The mice were continuously tracked and live behaviour observations were done. The animals showed normal physiological development. The Roaming Entropy (RE), a measure for the evenness of their usage of the enclosure, describes the exploration behaviour of each animal. Cumulatively acquired RE scores (cRE) within an enclosure increasingly diverged with time. Small differences at the beginning were not predictive of the end values. Thus, the animals became different through the continued interaction with environment and conspecifics. Moreover, the cRE values at the end point positively correlated with the amount of hippocampal neurogenesis. This proves that factors emerging during development contribute to individuality development. These factors at the same time shape and rely on plastic brain structures. Behavioural analyses showed that animals with a high amount of antenna contacts (most active, MA mice) were not necessarily those with high cRE values. MA mice were more often involved in social interactions than the least active mice (least active, LA), accumulated lower cRE scores over time and seemed to be lower in the social hierarchy. In conclusion, the amount of spatial exploration and gradual broadening of experience was linked to brain plasticity in the form of elevated levels of hippocampal neurogenesis. The data shows that animals with same preconditions still develop along increasingly divergent, individual paths. This is probably partly given through slightly different epigenetic preconditions, drifting further apart by interaction with the complex environment. Also, individuation seems to be inherent in living organisms and necessary for evolutionary processes. The study shows firstly that differences in individual behaviour and brain structure are defined not only by genes and the environment but also modulated by factors unfolding or emerging during ontogenetic development. The present paradigm moreover introduces an animal model for studying mechanisms and influences on the structural basis of plasticity as an individual response to the nonshared environment.

The schooling of twins can be daunting and challenging for twins, parents and educators. Separation or non-separation during the foundation phase cannot be left to chance. The process of deciding whether it is in both twins’ best interest to school them together or separately relies on various factors, which includes premature birth, individuality, dominance, relationship type and friendship-forming patterns. Parties involved in making the decision must consider each twin’s emotional, cognitive, behavioural, and social development. Premature separation of twins can lead to internal as well as external behaviour problems, while non-separation of mature twins may be detrimental to each twin’s individual progress and development. The study aimed to identify the determining factors when deciding upon schooling twins together or separately when they enter into the foundation phase. Existing school policies regarding classroom allocation of twins were considered. Three sets of twins, including teachers, parents, twins and other significant individuals involved in the process of separation or non-separation, were interviewed. Based on the findings, recommendations were made to assist parents and educators in making informed decisions about the schooling of twins. / Psychology of Education / M. Ed.

本文試圖藉由齊美爾（Georg Simmel）的社會學觀點指出現代個體的困境，並且參照齊美爾的美學觀點作為個體的出路。假若在大都會生活的社會互動中所面臨的冷漠和物化是個體能動性的宿命，那麼社會衝突和分化的機制就是個體能動性的機會。本文首先藉由「應然」的倫理學前提理解齊美爾個體生命的能動特性。然後，本文將此倫理置入理性社會與感性藝術的雙元環境中考察應然個體的可能。最後，本文將要以十九世紀印象派畫作為理論闡釋的實踐案例，意即從印象派的繪畫風格中經驗證成並且反身思考個體性的概念。 本論文的理論概念和經驗案例一致指向十九世紀作為我們討論的關鍵時期。這一方面是由於當時的西歐社會在政治面經歷了激烈的轉變（例如法國大革命促進了自由與平等的價值），此外經濟面也有了重大的改變（比如工業革命帶動了科技和藝術的發明）。但是，若我們僅是把政治經濟的理性史作為研究焦點，則將會陷入階級、國族或是群眾等集體現實的客觀陷阱，更別說已預設了革命的世俗神學。相對而言，藝術作品經常以非人事物的潛在形象當作客體追求，因而有別於政治事件總是以人群的顯著意義激化主體思辨。再者，此時社會的經濟面已明顯地趨向理性化發展，也使得人們倍感個體性喪失的威脅。因而，深入考察藝術創作與工業技術的奮戰或許反而較有助於發現個體性的潛能。 工業發展造就了攝影技術的產生，並使得傳統的繪畫藝術遭受挑戰。在擬真程度上，繪畫雖然永遠比不上攝影精準，然而印象派注重光與影的效果卻為藝術創作找到了新路。畫作上感性的自我表露反而得以創造攝影技術難以觸及的生命層次。莫內（Claude Monet）的自然紀錄與與卡莎特（Mary Stevenson Cassatt）的社會觀察儼然都是印象派藝術家以獨特的藝術作品具體實踐個體性的豐碩成果。 / This thesis attempts to illustrate the predicament of the modern individual from the sociological viewpoint of Georg Simmel. We assume that the aesthetical viewpoint of Georg Simmel could be the way out for the individual. Given the indifference and objectification of social interaction in the metropolis is the fate of individual agency, the mechanism of social conflict and differentiation is the opportunity for individual agency. This study begins with Georg Simmel’s theory that we utilize the ethics of ‘sollen’ (ought) to interpret the agency of the individual’s life. After depicting the outline of the Georg Simmel’s ethics, we place the theory into the dual condition set by rational society and affective art to explore the possibility of the ‘sollen’ individual. In the final part, we take some paintings from the 19th century impressionism as practical examples of explication. We verify and think reflexively on the concept of individuality by means of the painting style of impressionism. The theoretical concepts as well as the empirical examples of this thesis consistently point to the crucial period of the 19th century as our primal object for discussion. On the one hand, European society at the time had undergone radical changes on the political front (such as French Revolution which exalted the values of freedom and equality). In addition, there was great structural shifts on the economic front (such as Industrial Revolution which drove the inventions of technology and art). Nevertheless, if we take only the rational history of political economy as the focus of research, we would fall into a trap of objectivity interwoven in the collective realities of the classes, nations, or masses, not to mention the presumption of a secular theology of the Revolution. Comparatively speaking, the potential image of inhuman things is frequently the objective pursuit of the artwork. Therefore, it is different from the political state of affairs which always inspires and intensifies subjective speculation with those obvious meanings inherent in the human collectivity. Moreover, the economic aspect of society has now apparently developed towards rationalization, which makes people feel the doubling threat of individual deprivation. In light of these concerns, we look elsewhere into the creativity of the artwork and the struggle of industrial technique in order to discover the potentials of individuality. The development of industry brought forward the photographic apparatus, which posed in turn a challenge to the traditional art of painting. On the scale of verisimilitude, photography will always be much more accurate than painting. However, the fact that impressionism pays attention to the effects of light and shadow on the canvases opens a new way for artistic creation. The affective disclosure of individual selves represented by the impressionist style of painting can create a vital dimension that beyond the photographic technique. Claude Monet’s documentations of nature and Mary Stevenson Cassatt’s observations of society are both fruitful results from which these impressionist artists practice their concrete individualities through their singular artworks.

The participants were 76 adult twins (31 males and 45 females). The employed instruments included Individuality Inventory for Twins, Parental Rearing Behavior Inventory for Twins, and Attachment Relationship Inventory for Twins. The applied analysis methods were Descriptive Statistics, One-way Multivariate Analysis of Variance, One-way Analysis of Variance, and Multiple Regression. The main findings of this study were as follows: 1. The adult twins in this study had an above-average level of individuality and attachment relationship. As for the categories, most twins belonged to the attachment of “safe heaven” and “proximity seeking,” and most twins belonged to the parental rearing behavior of “emotional warmth”. 2. The adult twins’ age and socioeconomic status had significant effects on their performance of individuality. However, the adults twins’ gender, zygosity, birth order of twins, number of siblings, and their parents’ socioeconomic status had no significant effects on their performance of individuality. 3. The adult twins who experienced different parental rearing behaviors had varied level of individuality. More specifically, those who experienced more parental behaviors of “emotional warmth” outperformed their counterparts in overall individuality and the index of “differentiation,” while those who experienced less “rejection” behaviors from their fathers outperformed their counterparts in the index of “independence”. 4. Adult twins with different attachment relationship did not differ in their performance of individuality. 5. Father’s and mother’s rearing behaviors of “emotional warmth” and the attachment of “proximity seeking” and “safe heaven,” especially father’s rearing behaviors of “emotional warmth,” could positively predict the adult twins’ performance of individuality. 6. Father’s and mother’s rearing behaviors of “rejection” and “consistency” and the attachment of “separation protest,” especially father’s rearing behaviors of “rejection,” could negatively predict the adult twins’ performance of individuality. Finally, after discussion, some suggestions were proposed for the parents of twins and future research. Keywords: Adult Twins, Individuality, Parental Rearing Behaviors, Attachment Relationship.

This critical design project showcases obstacles that the Qatari culture and society impose on their female youth, hindering them from becoming independent individuals. It critiques the society and its social pressures. The project stimulates people to think by challenging their assumptions and perceptions, specifically social perception and judgment, family authority, and gender favoritism. This is achieved through hybridized accessories that are embedded with a meta-meaning that arouses curiosity, invites questions, and stimulates thoughts. Through the design of these appealing, high quality, and functionally viable everyday accessories, the project aims to communicate the social and cultural forces which impede Qatari female youths’ becoming individuals who dream, achieve, and thrive.

Ce mémoire propose une étude de la théorie de l’individualité biologique développée par Turner, des problèmes inhérents à celle-ci ainsi qu’une approche qui permet de surmonter les problèmes de la théorie de Turner tout en prenant en compte les aspects importants de cette dernière. Nous montrerons en premier lieu pourquoi, selon Turner, l’individualité est une question écologique et que l’individu ne peut être compris sans ses parties abiotiques si celles-ci jouent un rôle dans la fonctionnalité de l’individu. Par la suite, nous démontrerons que l’approche de Turner est sujette au problème du paradigme développé par Haber. Enfin, en s’inspirant de la théorie de l’individualité de Dupré et O’Malley et de leurs études sur les bactéries, nous forgerons une nouvelle théorie portée sur la fonctionnalité, qualifiée d’approche méréologique, qui surmonte les problèmes exposés tout en prenant en compte le rôle que les parties abiotiques jouent dans le fonctionnement de l’individu. / This master’s thesis consists in a study of the theory of biological individuality developed by Turner, its problems, as well as an approach of individuality that allows us to overcome Turner’s problems while also taking into account the important aspects of his theory. We will start off by showing that, according to Turner, individuality is an ecological matter since an individual cannot be understood without its abiotic parts if the latter play a role in the individual’s functionality. Afterwards we will demonstrate that Turner’s theory is subject to Haber’s problem of the paradigm. Lastly, by building upon Dupré and O’Malley’s theory of individuality and their studies on bacteria, we will develop a new approach focused on functionality, named mereological approach, which overcomes the problems we find in Turner’s theory while also taking into account the role that abiotic parts play in the functionality of individuals.

L'identité des personnes dans l'espace numérique n'est pas définissable d'une seule manière, et son mode d'expression est multiple. En effet, un individu peut disposer de plusieurs identités dans le numérique et jouer des rôles sociaux différents suivant les contextes sociaux auxquels il est confronté. Mais quels peuvent être les effets de l'usage de ces masques identitaires ? L'identité des personnes dans le cadre des réseaux sociaux renvoie au questionnement de soi, et des autres. Le versant individualiste et le versant communautaire de cette identité constituent la trame de la construction identitaire de l'utilisateur. Aussi, il apparaît que la richesse mais aussi la complexité des réseaux tiennent au fait que le droit confond individu et identité. Le droit repose en effet sur une conception essentialiste de l'identité, par laquelle chacun est acteur de sa propre trajectoire. Mais l'individu ne vit pas seul, il vit en groupe et il est saisi dans un réseau de relations sociales. Aussi, concevoir une identité personnelle en marge de la réalité numérique revient à distinguer la personne de la notion de présence en ligne qui est éminemment déclarative et performative. Cela amène à reconsidérer la place de l'identité dans l'espace numérique. Pour appréhender la question de la construction de l'identité personnelle dans les réseaux sociaux, il faudra aborder les différentes approches qui visent à assurer à chacun une identité qui soit conforme à ses désirs. Il sera également nécessaire d'adapter les mesures existantes à la réalité virtuelle, afin d'établir un régime de l'identité personnelle plus sécurisé et respectueux des droits de la personnalité de chaque utilisateur. / The identity of people in the digital space cannot be defined in one way. Its mode of expression is multiple. In fact, an individual can have several identities in the digital environment. It can also play different social roles according to social contexts that it faces. But what are effects of using identity masks ? The individual's identity within the social networks refers to the self-questioning, and others. The individualistic side and the community side of this identity are the foundation of the building of user's identity. Moreover, it appears that the wealth and the complexity of networks are the result of the confusion made by the law between individual and identity. In fact, the law is based on an essentialist conception of identity, by which each player has its own trajectory. But the individual does not live alone, he lives in a group and it is part of a network of social relations. The identity is made in the interaction of a claimed identity for oneself and assigned by others. Also, develop a personal identity on the fringes of the digital reality is to distinguish the person of the concept of online presence which is eminently declarative and performative.All this leads to reconsider the place of identity in the digital space. To understand the question of the construction of personal identity in social network, different approaches will be detailed. Those approaches are aimed to ensure everyone an identity according his wishes. Also, it will be necessary to adapt the existing measures to the virtual reality, in order to establish a more secure regime of personal identity, in respect of the rights of each user's personnality.

Dans les pièces de William Shakespeare, les personnages sont souvent désignés par un nom commun, qui peut indiquer leur statut social (« Le Gentilhomme »), leur métier (« Le Jardinier »), leur origine géographique (« L’Égyptien ») ou encore leurs liens relationnels (« Le Père »). Ces désignations anonymes, c’est-à-dire qui n’attribuent pas de nom propre aux personnages, montrent que Shakespeare favorise une inscription de ces rôles dans une société hiérarchisée et étendue, à l’image du public qui assiste aux spectacles, lui-même composé d’un large spectre social. L’étude de leur identité formelle, à partir de tous les signes identificatoires qui permettent la fabrique des personnages — didascalies, costumes, accessoires, corps et parole —, confirme une conception des personnages anonymes ancrée dans l’identité sociale, au détriment de leur identité personnelle. La généricité du personnage anonyme lui permet alors le plus souvent de se mettre au service des héros nommés ou du groupe social auquel il appartient, suivant le principe de self-effacement, « effacement de soi », pour reprendre les termes de Molly Mahood et de Florence Yoon. Toutefois, le mouvement poétique de Shakespeare le conduit parfois à développer ces rôles qui semblent au premier abord mineurs, en travaillant une tension entre fonctionnalisation et individualisation. Leur rapport à l’altérité leur confère alors une identité interactive, socialement et théâtralement, qui façonne leur raison d’être sur la scène de théâtre. D’un anonymat générique, les personnages peuvent alors s’élever vers la sphère de l’universalité. / In William Shakespeare’s plays, characters are often called by common nouns, which can indicate social status (“Gentleman”), occupation (“Gardener”), geographic origin (“Egyptian”) or relationship (“Father”). This anonymous way of naming, which does not assign personal names to the characters, shows that Shakespeare stresses these parts’ affiliation to a ranked and extensive society, mirroring the audience attending the performance, which itself forms a large social spectrum. The study of their identification, based on all the signs which shape the characters — speech headings, costume, props, body, speech —, reasserts a conception of anonymous characters which highlights their social identity to the detriment of their personal identity. Thus, the genericity of the anonymous characters mainly allow them to support named heroes or their social group, according to the self-effacement principle, as Molly Mahood and Florence Yoon define it. However, Shakespeare’s poetical process leads him to develop parts, that may seem minor at first, by working the tension between their function and their individuality. Their relation to otherness gives them an interactive identity, socially and theatrically, which shapes their raison d’être. From generical anonymity, characters can thus rise up to the realm of universality.
