Drug addictions and sexual violence in childhood and adolescence: analyzing life stories

The sexual abuse suffered in childhood and adolescence, in addition to damage to physical and psychological health of the victim, is considered as an important risk factor for alcohol and drugs addiction, development of psychopathology and psychosocial damage in adulthood. In addition to the pain and humiliation that are submitted by the abuse, children and adolescents also experience shame and guilt which require them to adopt coping strategies to endure those feelings. The use of psychoactive substances is a recognized way of dealing with the pains of living. This work, which is of narrative style, analyses and discusses, through five case reports, chemical dependency as a result of sexual abuse suffered in childhood and/or adolescence. The eight subjects in this study are male and have suffered sexual violence in this age period of life. Their ages range from 23 years to 39 years, and all are admitted to a therapeutic community in a city in the interior of Sao Paulo state, in Brazil, for treatment of chemical dependency, being met by the Department of Psychology. The reasons for the choice of the participants for treatment modality for patients are: difficult to stop using drugs, even unwilling to take it, they have easy access to it; the feeling of losing control over their lives; by successive losses as a result of drug use, and for fear that their lives had a tragic ending. With the exception of two participants, the others do not classify that as a child suffered sexual violence. However, all attribute that facilitated their entry into the world of drugs. Seven participants experienced such violence in childhood (between 7 years and 9 years) and adolescence (age 14). The attackers were people closed to the victims—in the case of two victims, their families, with the exception of one participant who was raped by a stranger. Six participants declared themselves as homosexual. Another participant does not claim to be homosexual, but presents difficulties in terms of sexuality. Two participants are HIV positive. The start of psychoactive substances use occurred during adolescence (12 years to 17 years). The participants see drugs as an anesthetic to the pain of the soul, a way to get pleasure, but they get charged expensively, as it increases the feeling of emptiness, guilt, helplessness, worthlessness and hopelessness. Although participants have sought help to deal with addiction, it is noted that throughout the life course the issue of sexual violence was not treated. It was noted that the patients have a double stigma in society: the issue of drugs addiction and the orientation of sexual desire, because the majority of participants are homosexual. The results reinforce the need for effective action geared to accommodate the victims of sexual violence and effective preventive measures to prevent children and adolescents from being abused.

Dissidências existenciais de gênero: resistências e enfrentamentos ao biopoder

This article approaches the questions about the sexes, genders, desires and sexual standardization practices, starting from the appearance of new sexual identities that can be classified as queer – travesty, transsexual and transgender people. Still, we problematize how the manners of established forms of subjectivity and the hegemonic institutions marginalize such forms of existences, because of the immense difficulty in the encounter with the stranger, the different and the unusual. With those analyses, we are trying to provide the creation of devices to reduce the intensities of the discrimination, of the stigmatization, of the violence, so frequently lived by the people dissident from the heterosexual gender normative, what was reported about their own lived experiences.

Spectroscopic and Catalytic Characterization of a Functional (FeFeII)-Fe-III Biomimetic for the Active Site of Uteroferrin and Protein Cleavage

A mixed-valence complex, [Fe(III)Fe(II)L1(mu-OAc)(2)]BF4 center dot H2O, where the ligand H(2)L1 = 2-{[[3-[((bis-(pyridin-2-ylmethyl)amino)methyl)-2-hydroxy-5-methylbenzyl](pyridin-2-ylmethyl)amino]methyl]phenol}, has been studied with a range of techniques, and, where possible, its properties have been compared to those of the corresponding enzyme system purple acid phosphatase. The (FeFeII)-Fe-III and Fe-2(III) oxidized species were studied spectroelectrochemically. The temperature-dependent population of the S = 3/2 spin states of the heterovalent system, observed using magnetic circular dichroism, confirmed that the dinuclear center is weakly antiferromagnetically coupled (H = -2JS(1).S-2, where J = -5.6 cm(-1)) in a frozen solution. The ligand-to-metal charge-transfer transitions are correlated with density functional theory calculations. The (FeFeII)-Fe-III complex is electron paramagnetic resonance (EPR)-silent, except at very low temperatures (<2 K), because of the broadening caused by the exchange coupling and zero-field-splitting parameters being of comparable magnitude and rapid spin-lattice relaxation. However, a phosphate-bound Fe-2(III) complex showed an EPR spectrum due to population of the S-tot = 3 state (J= -3.5 cm(-1)). The phosphatase activity of the (FeFeII)-Fe-III complex in hydrolysis of bis(2,4-dinitrophenyl)phosphate (k(cat.) = 1.88 x 10(-3) s(-1); K-m = 4.63 x 10(-3) mol L-1) is similar to that of other bimetallic heterovalent complexes with the same ligand. Analysis of the kinetic data supports a mechanism where the initiating nucleophile in the phosphatase reaction is a hydroxide, terminally bound to Fe-III. It is interesting to note that aqueous solutions of [Fe(III)Fe(II)L1(mu-OAc)(2)](+) are also capable of protein cleavage, at mild temperature and pH conditions, thus further expanding the scope of this complex's catalytic promiscuity.

Rafael Moneo: la complessità del vuoto. Dalle matrici formali dell'opera di Oteiza e Chillida

The experience of void, essential to the production of forms and to make use them, can be considered as the base of the activities that attend to the formative processes. If void and matter constitutes the basic substances of architecture. Their role in the definition of form, the symbolic value and the constructive methods of it defines the quality of the space. This job inquires the character of space in the architecture of Moneo interpreting the meaning of the void in the Basque culture through the reading of the form matrices in the work of Jorge Oteiza and Eduardo Chillida. In the tie with the Basque culture a reading key is characterized by concurring to put in relation some of the theoretical principles expressed by Moneo on the relationship between place and time, in an unique and specific vision of the space. In the analysis of the process that determines the genesis of the architecture of Moneo emerges a trajectory whose direction is constructed on two pivos: on the one hand architecture like instrument of appropriation of the place, gushed from an acquaintance process who leans itself to the reading of the relations that define the place and of the resonances through which measuring it, on the other hand the architecture whose character is able to represent and to extend the time in which he is conceived, through the autonomy that is conferred to them from values. Following the trace characterized from this hypothesis, that is supported on the theories elaborated from Moneo, surveying deepens the reading of the principles that construct the sculptural work of Oteiza and Chillida, features from a search around the topic of the void and to its expression through the form. It is instrumental to the definition of a specific area that concurs to interpret the character of the space subtended to a vision of the place and the time, affine to the sensibility of Moneo and in some way not stranger to its cultural formation. The years of the academic formation, during which Moneo enters in contact with the Basque artistic culture, seem to be an important period in the birth of that knowledge that will leads him to the formulation of theories tied to the relationship between time, place and architecture. The values expressed through the experimental work of Oteiza and Chillida during years '50 are valid bases to the understanding of such relationships. In tracing a profile of the figures of Oteiza and Chillida, without the pretension that it is exhaustive for the reading of the complex historical period in which they are placed, but with the needs to put the work in a context, I want to be evidenced the important role carried out from the two artists from the Basque cultural area within which Moneo moves its first steps. The tie that approaches Moneo to the Basque culture following the personal trajectory of the formative experience interlaces to that one of important figures of the art and the Spanish architecture. One of the more meaningful relationships is born just during the years of his academic formation, from 1958 to the 1961, when he works like student in the professional office of the architect Francisco Sáenz de Oiza, who was teaching architectural design at the ETSAM. In these years many figures of Basque artists alternated at the professional office of Oiza that enjoys the important support of the manufacturer and maecenas Juan Huarte Beaumont, introduced to he from Oteiza. The tie between Huarte and Oteiza is solid and continuous in the years and it realizes in a contribution to many of the initiatives that makes of Oteiza a forwarder of the Basque culture. In the four years of collaboration with Oiza, Moneo has the opportunity to keep in contact with an atmosphere permeated by a constant search in the field of the plastic art and with figures directly connected to such atmosphere. It’s of a period of great intensity as in the production like in the promotion of the Basque art. The collective “Blanco y Negro”, than is held in 1959 at the Galería Darro to Madrid, is only one of the many times of an exhibition of the work of Oteiza and Chillida. The end of the Fifties is a period of international acknowledgment for Chillida that for Oteiza. The decade of the Fifties consecrates the hypotheses of a mythical past of the Basque people through the spread of the studies carried out in the antecedent years. The archaeological discoveries that join to a context already rich of signs of the prehistoric era, consolidate the knowledge of a strong cultural identity. Oteiza, like Chillida and other contemporary artists, believe in a cosmogonist conception belonging to the Basques, connected to their matriarchal mythological past. The void in its meaning of absence, in the Basque culture, thus as in various archaic and oriental religions, is equivalent to the spiritual fullness as essential condition to the revealing of essence. Retracing the archaic origins of the Basque culture emerges the deep meaning that the void assumes as key element in the religious interpretation of the passage from the life to the death. The symbology becomes rich of meaningful characters who derive from the fact that it is a chthonic cult. A representation of earth like place in which divine manifest itself but also like connection between divine and human, and this manipulation of the matter of which the earth it is composed is the tangible projection of the continuous search of the man towards God. The search of equilibrium between empty and full, that characterizes also the development of the form in architecture, in the Basque culture assumes therefore a peculiar value that returns like constant in great part of the plastic expressions, than in this context seem to be privileged regarding the other expressive forms. Oteiza and Chillida develop two original points of view in the representation of the void through the form. Both use of rigorous systems of rules sensitive to the physics principles and the characters of the matter. The last aim of the Oteiza’s construction is the void like limit of the knowledge, like border between known and unknown. It doesn’t means to reduce the sculptural object to an only allusive dimension because the void as physical and spiritual power is an active void, that possesses that value able to reveal the being through the trace of un-being. The void in its transcendental manifestation acts at the same time from universal and from particular, like in the atomic structure of the matter, in which on one side it constitutes the inner structure of every atom and on the other one it is necessary condition to the interaction between all the atoms. The void can be seen therefore as the action field that concurs the relations between the forms but is also the necessary condition to the same existence of the form. In the construction of Chillida the void represents that counterpart structuring the matter, inborn in it, the element in absence of which wouldn’t be variations neither distinctive characters to define the phenomenal variety of the world. The physics laws become the subject of the sculptural representation, the void are the instrument that concurs to catch up the equilibrium. Chillida dedicate himself to experience the space through the senses, to perceive of the qualities, to tell the physics laws which forge the matter in the form and the form arranges the places. From the artistic experience of the two sculptors they can be transposed, to the architectonic work of Moneo, those matrices on which they have constructed their original lyric expressions, where the void is absolute protagonist. An ambit is defined thus within which the matrices form them drafts from the work of Oteiza and Chillida can be traced in the definition of the process of birth and construction of the architecture of Moneo, but also in the relation that the architecture establishes with the place and in the time. The void becomes instrument to read the space constructed in its relationships that determine the proportions, rhythms, and relations. In this way the void concurs to interpret the architectonic space and to read the value of it, the quality of the spaces constructing it. This because it’s like an instrument of the composition, whose role is to maintain to the separation between the elements putting in evidence the field of relations. The void is that instrument that serves to characterize the elements that are with in the composition, related between each other, but distinguished. The meaning of the void therefore pushes the interpretation of the architectonic composition on the game of the relations between the elements that, independent and distinguished, strengthen themselves in their identity. On the one hand if void, as measurable reality, concurs all the dimensional changes quantifying the relationships between the parts, on the other hand its dialectic connotation concurs to search the equilibrium that regulated such variations. Equilibrium that therefore does not represent an obtained state applying criteria setting up from arbitrary rules but that depends from the intimate nature of the matter and its embodiment in the form. The production of a form, or a formal system that can be finalized to the construction of a building, is indissolubly tied to the technique that is based on the acquaintance of the formal vocation of the matter, and what it also can representing, meaning, expresses itself in characterizing the site. For Moneo, in fact, the space defined from the architecture is above all a site, because the essence of the site is based on the construction. When Moneo speaks about “birth of the idea of plan” like essential moment in the construction process of the architecture, it refers to a process whose complexity cannot be born other than from a deepened acquaintance of the site that leads to the comprehension of its specificity. Specificity arise from the infinite sum of relations, than for Moneo is the story of the oneness of a site, of its history, of the cultural identity and of the dimensional characters that that they are tied to it beyond that to the physical characteristics of the site. This vision is leaned to a solid made physical structure of perceptions, of distances, guideline and references that then make that the process is first of all acquaintance, appropriation. Appropriation that however does not happen for directed consequence because does not exist a relationship of cause and effect between place and architecture, thus as an univocal and exclusive way does not exist to arrive to a representation of an idea. An approach that, through the construction of the place where the architecture acquires its being, searches an expression of its sense of the truth. The proposal of a distinction for areas like space, matter, spirit and time, answering to the issues that scan the topics of the planning search of Moneo, concurs a more immediate reading of the systems subtended to the composition principles, through which is related the recurrent architectonic elements in its planning dictionary. From the dialectic between the opposites that is expressed in the duality of the form, through the definition of a complex element that can mediate between inside and outside as a real system of exchange, Moneo experiences the form development of the building deepening the relations that the volume establishes in the site. From time to time the invention of a system used to answer to the needs of the program and to resolve the dual character of the construction in an only gesture, involves a deep acquaintance of the professional practice. The technical aspect is the essential support to which the construction of the system is indissolubly tied. What therefore arouses interest is the search of the criteria and the way to construct that can reveal essential aspects of the being of the things. The constructive process demands, in fact, the acquaintance of the formative properties of the matter. Property from which the reflections gush on the relations that can be born around the architecture through the resonance produced from the forms. The void, in fact, through the form is in a position to constructing the site establishing a reciprocity relation. A reciprocity that is determined in the game between empty and full and of the forms between each other, regarding around, but also with regard to the subjective experience. The construction of a background used to amplify what is arranged on it and to clearly show the relations between the parts and at the same time able to tie itself with around opening the space of the vision, is a system that in the architecture of Moneo has one of its more effective applications in the use of the platform used like architectonic element. The spiritual force of this architectonic gesture is in the ability to define a place whose projecting intention is perceived and shared with who experience and has lived like some instrument to contact the cosmic forces, in a delicate process that lead to the equilibrium with them, but in completely physical way. The principles subtended to the construction of the form taken from the study of the void and the relations that it concurs, lead to express human values in the construction of the site. The validity of these principles however is tested from the time. The time is what Moneo considers as filter that every architecture is subordinate to and the survival of architecture, or any of its formal characters, reveals them the validity of the principles that have determined it. It manifests thus, in the tie between the spatial and spiritual dimension, between the material and the worldly dimension, the state of necessity that leads, in the construction of the architecture, to establish a contact with the forces of the universe and the intimate world, through a process that translate that necessity in elaboration of a formal system.

Il contributo della psicopatologia ansiosa materna prenatale sul temperamento infantile e la relazione precoce madre-bambino

La sintomatologia ansiosa materna nel periodo prenatale risulta influire negativamente non sullo stato materno ma anche sul successivo sviluppo infantile, Tuttavia, sono limitati gli studi che hanno considerato lo specifico contributo dei disturbi d’ansia nel periodo prenatale. L’obiettivo generale dello studio è quello di indagare nel primo periodo post partum la relazione tra psicopatologia ansiosa materna e: temperamento e sviluppo neonatale, qualità del caregiving materno e dei pattern interattivi madre-bambino. 138 donne sono state intervistate utilizzando SCID-I (First et al., 1997) durante il terzo trimestre di gravidanza. 31 donne (22,5%) presentano disturbo d’ansia nel periodo prenatale. A 1 mese post partum il comportamento del neonato è stato valutato mediante NBAS (Brazelton, Nugent, 1995), mentre le madri hanno compilato MBAS (Brazelton, Nugent, 1995). A 3 mesi postpartum, una sequenza interattiva madre-bambino è stata videoregistrata e codificata utilizzando GRS (Murray et al., 1996). La procedura dello Stranger Episode (Murray et al., 2007) è stata utilizzata per osservare i pattern interattivi materni e infantili nell’interazione con una persona estranea. I neonati di madri con disturbo d’ansia manifestano alle NBAS minori capacità a livello di organizzazione di stati comportamentali, minori capacità attentive e di autoregolazione. Le madri ansiose si percepiscono significativamente meno sicure nell’occuparsi di loro, valutando i propri figli maggiormente instabili e irregolari. Nell’interazione face to face, esse mostrano comportamenti significativamente meno sensibilI, risultando meno coinvolte attivamente con il proprio bambino. Durante lo Stranger Episode, le madri con fobia sociale presentano maggiori livelli di ansia e incoraggiando in modo significativamente inferiore l’interazione del bambino con l’estraneo. I risultati sottolineano l’importanza di valutare in epoca prenatale la psicopatologia ansiosa materna. Le evidenze confermano la rilevanza che può assumere un modello multifattoriale di rischio in cui i disturbi d’ansia prenatali e la qualità del caregiving materno possono agire in modo sinergico nell’influire sugli esiti infantili.

Studio di alcuni tratti del temperamento nel cane

Il temperamento può essere definito come l’attitudine che un cane esprime verso le persone e verso altri animali, la combinazione di tratti fisici e mentali, acquisiti e non, che determinano il comportamento del cane. Tale parametro delinea perciò il carattere di un individuo, inclinazioni e tendenze, eccitabilità, tristezza, rabbia e il modo caratteristico di comportarsi di un individuo, con particolare riferimento alle interazioni sociali. La presente tesi di Dottorato rappresenta uno studio su alcuni tratti del temperamento nel cane domestico elaborato in 3 progetti sperimentali. Nei primi due progetti sono state analizzate le differenze attitudinali tra alcune razze canine attraverso l’applicazione di un test di temperamento in cuccioli di 60 giorni e in cani adulti, per valutare e confrontarne il temperamento, la socialità ed identificare profili tipici di razza. Nel terzo progetto un campione di cani morsicatori di canile e di proprietà è stato confrontato con due rispettivi gruppi di controllo. Analizzando i risultati è stato possibile mettere in evidenza caratteristiche di razza omogenee nell’interazione con stimoli inanimati, nelle interazioni sociali e in relazione alla possessività e sono stati delineati profili di razza sia nei cuccioli sia negli adulti. Si sono tuttavia, osservate variabilità individuali, intra-razza e intra-cucciolata, a testimonianza dell’influenza complessa e multifattoriale delle componenti genetica e ambientale sul comportamento dei cani. Il confronto tra cani morsicatori di canile e di proprietà ha messo in luce interessanti differenze tra i soggetti in termini di reattività, socievolezza, propensione all’interazione con il proprietario o con un estraneo, comportamenti di evitamento e velocità di reazione agli stimoli presentati. Il test applicato è risultato un valido strumento per valutare il temperamento di cani dichiarati aggressivi che sono stati sottoposti a situazioni nuove e a stimoli sconosciuti per poter ottenere una migliore visione d’insieme del temperamento del soggetto.

„Abgeschoben in die Marginalität“ - Eine empirische Untersuchung zur problematischen Eingliederung der wegen Straffälligkeit aus Deutschland abgeschobenen türkischen Staatsangehörigen in der türkischen Gesellschaft

Die vorliegende Arbeit zeigt anhand von Einzelfällen, welche Probleme und Folgen eine Ausweisung und/oder Abschiebung von kriminell gewordenen Angehörigen der sogenannten zweiten Generation türkischer Staatsangehöriger im Hinblick auf deren Eingliederung in die türkische Gesellschaft mit sich bringt.rnDem Bereich der Ausweisung und/oder Abschiebung – beides Formen von Zwangsmigration – ausländischer Staatsangehöriger in ihr Herkunftsland wurde bislang im weiten Feld der Integrationsforschung kaum Aufmerksamkeit geschenkt. Nicht anders verhält es sich in der politischen und öffentlichen Diskussion, wenn es um die „Entfernung“ kriminell gewordener Ausländer, die mitunter in Deutschland geboren und aufgewachsen sind oder sich bereits viele Jahre in der Bundesrepublik aufhalten, aus dem Bundesgebiet geht. Bei dieser Diskussion wird zwar die Bestrafung kriminell gewordener Ausländer mittels Ausweisung und/oder Abschiebung vorschnell befürwortet, besonders in solch spektakulären Fällen, wie in dem des Jugendlichen Muhlis Arı, genannt „Mehmet“ oder in dem des als „Münchner U-Bahn Schläger“ bekannt gewordenen Serkan. Die weitreichenden Folgen für den Einzelnen werden in der Regel jedoch nicht tiefergehend betrachtet.rnDeshalb steht im Zentrum dieser Arbeit die Frage, wie sich die Eingliederung von in Deutschland geborenen und hier aufgewachsenen Nachkommen der „Gastarbeiter“-Generation sowie später nachgeholter Kinder im Anschluss an eine Ausweisung und/oder Abschiebung in die türkische Gesellschaft gestaltet. Die theoretische Grundlage der Untersuchung bilden vier theoretische Konzepte zu Integration, Fremdheit und Marginalität. Dabei handelt es sich um die „Integrationstheorie“ von Hartmut Esser, das Konzept des „bleibenden Fremden“ von Georg Simmel, das des „einwandernden Fremden“ von Alfred Schütz sowie um das Konzept des „marginal man“ von Robert E. Park. Auf Basis dieser vier theoretischen Konzepte und der Auswertung des erhobenen empirischen Datenmaterials wird deutlich, dass hohe soziale Barrieren auf Seiten der Mitglieder der türkischen Aufnahmegesellschaft, mangelnde integrationsförderliche Opportunitäten, aber auch eine geringe Motivation auf Seiten der Betroffenen zur Aufnahme integrationsförderlicher Handlungen eine Integration verhindern. Die von Ausweisung und/oder Abschiebung Betroffenen sind letztlich dazu gezwungen, dauerhaft ein Leben am Rande der Gesellschaft in der Marginalität zu führen.rn

La sociologia relazionale di Georg Simmel. La relazione come forma sociale vitale

La tesi di dottorato ha come oggetto il pensiero sociologico di Georg Simmel con particolare riferimento alla sua interpretazione nei diversi indirizzi di ricerca della sociologia relazionale contemporanea. In particolare, si propone una rilettura del contributo simmeliano alla luce del paradigma relazionale della sociologia di Pierpaolo Donati. Il lavoro di ricerca è stato condotto secondo una rigorosa ricognizione testuale dell’opus simmeliano e della bibliografia critica internazionale sull'argomento in oggetto. A partire dalla nozione di relazione sociale, si dipana l’analisi della proposta sociologica simmeliana: il termine tedesco Wechselwirkung (azione reciproca) racchiude la complessa semantica con cui assume senso l’intera teoria sociologica simmeliana. Simmel è il primo "sociologo relazionale", come sostenuto da Donati, e in questa ricerca si cerca di mostrare le evidenze della validità di tale asserzione. Nella formulazione simmeliana si trovano importanti indizi teorici che permettono di rielaborare la relazione nei termini di una “forma sociale vitale”. Questo significa che la relazione sociale trova la sua ragion d’essere in quanto fenomeno umano che si determina a partire dalle nozioni di “spirito” (Geist) e “vita”(Leben). Nel primo capitolo si chiarisce la natura di questa relazione sociale in rapporto alle varie proposte sociologiche relazionali in campo internazionale. Nel secondo capitolo si analizza in maniera critica la (ri)formulazione simmeliana della relazione come scambio (nella forma simbolica del denaro) e le interpretazioni relazionali che si sono succedute a partire da questo cambio di rotta. Nel terzo capitolo vengono passate in rassegna le principali figure relazionali (la vita della metropoli, la moda, il conflitto, il povero, lo straniero) con le quali si confronta il sociologo berlinese. Nel quarto capitolo si propone di rileggere fenomeni sociali e culturali come forme relazionali in riferimento alla sfera dell’arte e della teologia (religione).

[Examination results and autopsy findings in assaults on elderly people]

As the percentage of elderly people in the population grows, violence against persons of advanced age constitutes an increasing social problem. The findings of the clinical forensic examinations (CE group) and autopsies performed on elderly violence victims (> or = 60 years) between 1999 and 2008 at the Institute of Legal Medicine of the Hanover Medical School were retrospectively analysed. In all, the study material comprised 55 victims of the CE group (35 females and 20 males, median age 73.5 years) and 55 autopsies (33 females and 22 males, median age 72.7 years). In most of the autopsy cases, the suspect was a family member or partner. In contrast, the alleged perpetrator was a stranger in most cases of the CE group. Blunt force injuries were most often found in the CE group victims (63.6%). Altogether, 38.2% (CE group) and 20.0% (autopsy cases) of the violent assaults were associated with robbery. In the majority of the CE cases, the victims suffered potentially or acute life-threatening injuries. In summary, the analysis shows that elderly people frequently become victims of robbery and blunt force injury. In most homicides of old people, the perpetrator is familiar to the victim. In surviving elderly violence victims, the assault is more likely to be reported to the police if the suspect is a stranger.

[Examination reports on survived strangulation cases]

Clinical-forensic examination of strangulation victims is an increasing part of the routine of many forensic pathology institutes. The cases examined between 2004 and 2008 at the Institute of Legal Medicine of the Hanover Medical School were retrospectively analysed. In total, the study material comprised 218 victims (175 females and 43 males). In 80.7 %, the clinical-forensic examination was performed within 24 hours after the incident. In the overwhelming number of cases, the alleged perpetrator was no stranger. 128 victims (58.7 %) had strangulation marks, 32 victims (14.7 %) ligature marks and 65 victims (29.8 %) nail marks. Four victims showed injuries of the laryngeal and pharyngeal structures (reddening, hematomas, swelling and in one case a fracture of the cricoid cartilage on both sides). Extensive petechiae were predominantly seen in the conjunctivae, the buccal mucosa and the skin of the face in cases where the victims suffered a loss of consciousness. 87 cases (39.9% were classified as potentially life-threatening and 30 cases (13.8 %) as acute life-threatening events. This classification is of legal relevance for the penalty. In addition, 60 victims experienced sexual violence. These results suggest that early clinical-forensic examination is crucial for documenting forensic evidence in support of police investigations and may deliver significant details relevant in court.

The Effect of Chronic Estrogen Administration on Same-Sex Social Behavior and Central Oxytocin Levels in Prairie Voles (Microtus ochrogaster)

The purpose of our study is to investigate the effects of chronic estrogen administration on same-sex interactions during exposure to a social stressor and on oxytocin (OT) levels in prairie voles (Microtus orchrogaster). Estrogen and OT are two hormones known to be involved with social behavior and stress. Estogen is involved in the transcription of OT and its receptor. Because of this, it is generally thought that estrogen upregulates OT, but evidence to support this assumption is weak. While estrogen has been shown to either increase or decrease stress, OT has been shown to have stress-dampening properties. The goal of our experiment is to determine how estrogen affects OT levels as well as behavior in a social stressor in the voles. In addition, estrogen is required for many opposite-sex interactions, but little is known about its influence on same-sex interactions. We hypothesized that prairie voles receiving chronic estrogen injections would show an increase in OT levels in the brain and alter behavior in response to a social stressor called the resident-intruder test. To test this hypothesis, 73 female prairie voles were ovariectomized and then administered daily injections of estrogen (0.05 ¿g in peanut oil, s.c.) or vehicle for 8 days. On the final day of injections, half of the voles were given the resident-intruder test, a stressful 5 min interaction with a same-sex stranger. Their behavior was video-recorded. These animals were then sacrificed either 10 minutes or 60 minutes after the conclusion of the test. Half of the animals (no stress group) were not given the resident-intruder test. After sacrifice, trunk blood and brains were collected from the animals. Videos of the resident-intruder tests were analyzed for pro-social and aggressive behavior. Density of OT-activated neurons in the brain was measured via pixel count using immunohistochemistry. No differences were found in pro-social behavior (focal sniffing, p = 0.242; focal initiated sniffing p = 0.142; focal initiated sniffing/focal sniffing, p = 0.884) or aggressive behavior (total time fighting, p= 0.763; number of fights, p= 0.148; number of strikes, p = 0.714). No differences were found in activation of OT neurons in the brain, neither in the anterior paraventricular nucleus (PVN) (pixel count p= 0.358; % area that contains pixelated neurons p = 0.443) nor in the medial PVN (pixel count p= 0.999; % area that contains pixelated neurons p = 0.916). These results suggest that estrogen most likely does not directly upregulate OT and that estrogen does not alter behavior in stressful social interactions with a same-sex stranger. Estrogen may prepare the animal to respond to OT, instead of increasing the production of the peptide itself, suggesting that we need to shift the framework in which we consider estrogen and OT interactions.

ON THE DIGITAL-POLITICAL TOPOGRAPHY OF MUSIC

The persuasive power of music is often relegated to the dimension of pathos: that which moves us emotionally. Yet, the music commodity is now situated in and around the liminal spaces of digitality. To think about how music functions, how it argues across media, and how it moves us, we must examine its material and immaterial realities as they present themselves to us and as we so create them. This dissertation rethinks the relationship between rhetoric and music by examining the creation, performance, and distribution of music in its material and immaterial forms to demonstrate its persuasive power. While both Plato and Aristotle understood music as a means to move men toward virtue, Aristotle tells us in his Laws, through the Athenian Stranger, that the very best kinds of music can help guide us to truth. From this starting point, I assess the historical problem of understanding the rhetorical potential of music as merely that which directs or imitates the emotions: that which “Soothes the savage breast,” as William Congreve writes. By furthering work by Vickers and Farnsworth, who suggest that the Baroque fascination with applying rhetorical figures to musical figures is an insufficient framework for assessing the rhetorical potential of music, I demonstrate the gravity of musical persuasion in its political weight, in its violence—the subjective violence of musical torture at Guantanamo and the objective, ideological violence of music—and in what Jacques Attali calls the prophetic nature of music. I argue that music has a significant function, and as a non-discursive form of argumentation, works on us beyond affect. Moreover, with the emergence of digital music distribution and domestic digital recording technologies, the digital music commodity in its material and immaterial forms allows for ruptures in the former methods of musical composition, production, and distribution and in the political potential of music which Jacques Attali describes as being able to foresee new political realities. I thus suggest a new theoretical framework for thinking about rhetoric and music by expanding on Lloyd Bitzer’s rhetorical situation, by offering the idea of “openings” to the existing exigence, audience, and constraints. The prophetic and rhetorical power of music in the aleatoric moment can help provide openings from which new exigencies can be conceived. We must, therefore, reconsider the role of rhetorical-musical composition for the citizen, not merely as a tool for entertainment or emotional persuasion, but as an arena for engaging with the political.

CHARACTERIZATION AND TREATMENT OF A NOVEL MOUSE MODEL OF TSC-ASSOCIATED AUTISM

Tuberous sclerosis complex (TSC) is a dominant tumor suppressor disorder caused by mutations in either TSC1 or TSC2. The proteins of these genes form a complex to inhibit the mammalian target of rapamycin complex 1 (mTORC1), which controls protein translation and cell growth. TSC causes substantial neuropathology, often leading to autism spectrum disorders (ASDs) in up to 60% of patients. The anatomic and neurophysiologic links between these two disorders are not well understood. However, both disorders share cerebellar abnormalities. Therefore, we have characterized a novel mouse model in which the Tsc2 gene was selectively deleted from cerebellar Purkinje cells (Tsc2f/-;Cre). These mice exhibit progressive Purkinje cell degeneration. Since loss of Purkinje cells is a well-reported postmortem finding in patients with ASD, we conducted a series of behavior tests to assess if Tsc2f/-;Cre mice displayed autistic-like deficits. Using the three chambered social choice assay, we found that Tsc2f/-;Cre mice showed behavioral deficits, exhibiting no preference between a stranger mouse and an inanimate object, or between a novel and a familiar mouse. Tsc2f/-;Cre mice also demonstrated increased repetitive behavior as assessed with marble burying activity. Altogether, these results demonstrate that loss of Tsc2 in Purkinje cells in a haploinsufficient background lead to behavioral deficits that are characteristic of human autism. Therefore, Purkinje cells loss and/or dysfunction may be an important link between TSC and ASD. Additionally, we have examined some of the cellular mechanisms resulting from mutations in Tsc2 leading to Purkinje cell death. Loss of Tsc2 led to upregulation of mTORC1 and increased cell size. As a consequence of increased protein synthesis, several cellular stress pathways were upregulated. Principally, these included altered calcium signaling, oxidative stress, and ER stress. Likely as a consequence of ER stress, there was also upregulation of ubiquitin and autophagy. Excitingly, treatment with an mTORC1 inhibitor, rapamycin attenuated mTORC1 activity and prevented Purkinje cell death by reducing of calcium signaling, the ER stress response, and ubiquitin. Remarkably, rapamycin treatment also reversed the social behavior deficits, thus providing a promising potential therapy for TSC-associated ASD.

La situación cívica de los judíos en los tratados de Filón

En los tratados de Filón, el concepto polítes "ciudadano" cumple un papel esencial en la tarea de comprender la configuración histórica y el funcionamiento de la comunidad dentro de la sociedad alejandrina porque permite conocer no solo cuál fue el lugar social ocupado por los judíos en la ciudad, sino también la relación entre los judíos y los demás grupos poblacionales que integraron el mismo espacio social. En nuestro estudio analizaremos entonces el uso cívico de polítes en Vida de Moisés y en los tratados históricos Contra Flaco y Embajada a Gayo, en conexión con el vocabulario y los eventos históricos que pueden ser incluidos dentro de los márgenes de su interpretación
