It was a transversal, analytical research. Subjects and Methods: The stratified sample was 212 students from a private university that used Facebook, Instagram and/or Twitter. To measure depressive symptoms, Beck Depression Inventory was used, and to measure the dependence to social media, the Social Media Addiction Test was used, adapted from the Internet Addiction Test of Echeburúa. The collected data were subjected for analysis by descriptive statistics where STATA12 was used. Results: The results show that there is an association between social media dependence and depressive symptoms (PR [Prevalence Ratio] = 2.87, CI [Confidence Interval] 2.03–4.07). It was also shown that preferring the use of Twitter (PR = 1.84, CI 1.21–2.82) over Instagram (PR = 1.61, CI 1.13–2.28) is associated with depressive symptoms when compared to the use of Facebook. Conclusion: Excessive social media use is associated with depressive symptoms in university students, being more prominent in those who prefer the use of Twitter over Facebook and Instagram. / Revisión por pares

The primary purpose of this study was to examine the underlying latent factor structure of the Trauma Inventory for Partners of Sex Addicts (TIPSA), a 53-item assessment designed to assess for Post-Traumatic Stress Disorder (PTSD) in the context of sexual addiction. It was theorized that the factor structure mirrored the 5 core criteria for PTSD as constituted in DSM-5. Data were gathered from 3,199 self-selected respondents (ages 21 to 55) who completed an online version of the TIPSA. Confirmatory Factor Analysis (CFA) was performed utilizing Mplus in order to confirm the hypothesized factor structure of the TIPSA. Several modifications were made to the model, based on factor loadings and modification indices, in order to improve goodness-of-fit. In addition to the original posited model, three other models were also examined: a second-order factor model; a general-factor model; and a bifactor model. The second-order factor model emerged as the model of choice, based on both statistical and theoretical underpinnings. As a result of the findings from this study, revision of the items contained in the TIPSA is recommended. In addition, in order to further establish the validity of the TIPSA as an assessment for PTSD, evaluating convergent and discriminant validity of the TIPSA with other established assessments, such as the National Institutes of Mental Health (NIMH) PTSD Checklist, is also suggested.

Les addictions constituent un problème majeur de santé publique et soulèvent de nombreuses questions sur le plan clinique et psycho-pathologique ainsi que sur leur prise en charge. Toutefois, si elles sont d’un intérêt certain dans le domaine de la recherche scientifique, ce n’est que récemment que la souffrance des proches, et plus encore celle des parents de jeunes adolescents, sont l’objet de travaux pour les chercheurs comme pour les professionnels.L’objectif de cette recherche qualitative et exploratoire est d’étudier les vécus des parents d’adolescents ayant des pratiques addictives. Elle est réalisée au sein d’un dispositif de prévention en addictologie.Ce sont en majorité des mères qui consultent pour leurs fils. Généralement, ces adolescents ou jeunes adultes sont âgés entre 15 et 23 ans, aux prises avec un problème de consommation de cannabis, d’alcool, de jeux vidéo et vivent chez leurs parents.Six formes de vécus parentaux et certaines configurations familiales en lien avec les conduites addictives des adolescents ont pu être identifiées à l’aide de quinze vignettes cliniques.Les addictions des jeunes interpellent la fonction maternelle, en tant que médiatrice de la fonction paternelle. De même, le sujet adolescent convoquerait chez la mère, un objet répondant à la question du réel d’une autre jouissance, en tant qu’une suppléance à l’absence de signifiant.Ces résultats permettent d’interroger les possibilités d’interventions en clinique auprès de ces familles d’une part, et de réfléchir à un nouveau dispositif d’accompagnement médico-psycho-social d’autre part. / Addiction constitutes a major public health problem and raises numerous questions from a clinical and psychopathological perspective as well as on young users’ care. Even though certain interest has been shown in the field of scientific research on the subject, only recently has the suffering of the parents of young teenagers been the object of researchers’ and professionals’ studies.The objective of this qualitative and exploratory study is to examine the personal experiences of the parents of teenagers suffering from addiction. It was carried out at a prevention and treatment center for addiction.Mothers who consult for their sons make up the majority of those who consult. Generally, these teenagers or grown-up young adults are between the ages of 15 and 23, live at home with their parents, and battle against excessive use of cannabis, alcohol, and video games.Six forms of parental personal experiences and certain family configurations in connection with the addictive behaviors of the teenagers were identified by means of fifteen clinical cases.The addictions of the young people in question call out to the maternal function as a mediator of the paternal function.Additionally, the adolescent subject summons within his/her mother an object in response to the question of the real of the Other jouissance, as a substitution in the absence of the signifier.These results allow us to question the possibilities of clinical interventions with these families, and to think about new tools of medical-psychosocial support.

This diploma thesis addresses the awareness of a selected group of girls aged 16-18 about the risks of alcohol, tobacco, marijuana and caffeine use in pregnancy. The aim is to find out their knowledge of this topic and on the basis of the obtained data to create a suitable pedagogical output. It should supplement and deepen their knowledge. Girls' awareness of the risks of using selected substances in pregnancy is determined by means of a questionnaire survey of a knowledge nature of 85 respondents. The results show that their knowledge is 59% and therefore it is appropriate for them to supplement it with the help of pedagogical output. KEYWORDS Awareness, girls, addictive substances, pregnancy

This research is a systematic study exploring a new fabrication methodology for long-fiber-reinforced metal matrix composites (MMCs) using a novel additive manufacturing technology. The research is devoted to the manufacture of long-fiber-reinforced MMC structures using the Ultrasonic Consolidation (UC) process. The main objectives of this research are to investigate the bond formation mechanisms and fiber embedment mechanisms during UC, and further to study the effects of processing parameters on bond formation and fiber embedment, and the resultant macroscopic mechanical properties of UC-made MMC structures. From a fundamental research point of view, bond formation mechanisms and fiber embedment mechanisms have been clarified by the current research based on various experimental observations. It has been found that atomic bonding across nascent metal is the dominant bond formation mechanism during the UC process, whereas the embedded fiber are mechanically entrapped within matrix materials due to significant plastic deformation of the matrix material during embedment. From a manufacturing process point of view, the effects of processing parameters on bond formation and fiber embedment during the UC process have been studied and optimum levels of parameters have been identified for manufacture of MMC structures. An energy-based model has been developed as a first step toward analytically understanding the effects of processing parameters on the quality of ultrasonically consolidated structures. From a material applications point of view, the mechanical properties of ultrasonically consolidated structures with and without the presence of fibers have been characterized. The effects on mechanical properties of UC-made structures due to the presence of embedded fibers have been discussed.

This thesis is an examination of the trapped lives of Marina Carr's female protagonists and their relevance to contemporary Irish women. In her six plays from The Mai to Woman and Scarecrow, each of Carr's female protagonists is trapped either in a liminal state, defined by Victor Turner as a phase in a rites of passage process, or in a patriarchal addictive society, defined by Anne Wilson Schaef as a society in which the power is maintained and perpetuated by white males with the help of all members of society including women. Portia (Portia Coughlan), Hester (By the Bog of Cats), and Sorrel (On Raftery's Hill) are trapped in a liminal state. As liminal characters, each of these women has the ability to discern the destructive nature of the addictive society around them and must therefore decide either to integrate into that society or remain in a liminal state. Since neither option is appealing, Portia and Hester choose to commit suicide rather than to submit themselves either to continual liminality or to the addictive society. Sorrel, however, chooses liminality, and her life attests to the stagnation accompanying such a choice. The Mai (The Mai¬), Elaine (Ariel), Frances (Ariel), and Woman (Woman and Scarecrow) choose to integrate into the addictive society. In so doing, they surrender their personal power and submit to the typical feminine roles and addictions of their society. Ultimately their submission to the addictive society leads each of these characters to a destructive end: The Mai commits suicide, Frances dies by Elaine's hand, and Woman lives a stagnant life and dies unfulfilled. Although Carr's protagonists are fictional, the liminal and addictive states that Carr's women experience mirror the situations that Irish women have encountered and continue to encounter today. Like their fictional counterparts, Irish women are frequently faced with either a liminal position outside of society or traditional women's roles within an addictive society"”both of which are destructive options as Carr's protagonists demonstrate through their own lives and deaths. Although Carr's protagonists do not appear to offer any solutions to these problems, her plays do meaningfully illuminate and name these problems that Irish women face.

Le jeu vidéo est une activité de loisir particulièrement répandue auprès des adolescents. Néanmoins, pour certains, une conduite addictive peut se mettre en place, remplissant une fonction précise et nécessaire à l'équilibre du sujet. L'objectif de ce travail de thèse est d'amorcer la construction d'un modèle explicatif de ce processus addictif. L'opérationnalisation de cette recherche repose sur une méthodologie quantitative permettant de mesurer le poids et l'implication de variables psychopathologiques, cognitivo-émotionnelles et de personnalité dans la mise en place de cette conduite addictive. Le monde virtuel et l'avatar sont les deux constituants majeurs de tout jeu vidéo. Ils permettent au sujet de mettre en scène et médiatiser son Soi Emotionnel. Le processus addictif résulte d'une cristallisation de cette dynamique, ne permettant pas au sujet de se réapproprier son expérience émotionnelle. Par ailleurs, ce travail a permis de mettre en avant l'existence d'une utilisation addictive des jeux vidéo en ligne et hors ligne. Ces deux formats se différencient dans la mise en scène d'aspects du Soi Identitaire qu'ils impliquent. Pour finir, ce travail nous amène à questionner la frontière entre une utilisation régulière et addictive/pathogène des jeux vidéo. / Video games cover preferential activity of adolescents. But for some, the practice becomes an addictive behavior, playing an important role in psychological functioning of adolescents. The global aim is to establish a comprehensive model of this addictive process. This research is based on a quantitative methodology in order to assess the weight and the involvement of psychopathological, emotional and personality variables in this addictive process. Avatar and virtual world are the two essential components of any video game. They allow subject to mediatize and enact his Emotional Self. The addiction process is the result of crystallization of this dynamic which does not allow the subject to reappropriate his emotional experience. Furthermore, the research puts the light on two different types of addictive processes with on line or outline video games. These two formats differ in the enacting of aspects of the Self Identity they imply. Finally, this work leads us to question the boundary between regular and addictive / pathogen use of video games.

My diploma thesis deals with the addictive substances in road transport, especially with alcohol and other narcotic drugs used by drivers of motorized and non-motorized vehicles. The thesis is divided into three main parts. First chapter provides the definition and clarification of the terms. Second chapter, Substantive law, contains two subchapters, Criminal law and Administrative law. The subchapter Criminal law analyzes crimes that can be committed in conjunction with the addictive substances in road transport, namely endangerment under influence of an addictive substance according to § 274 TZ, general endangerment and general endangerment alleging negligence according to § 272 TZ and § 273 TZ and inebriation according to § 360 TZ. The most attention is paid to the offence of endangerment under the influence of an addictive substance, which is, as the most frequently committed crime in connection with the addictive substances, analyzed in terms of elements of crime, complicity and participation, stages of the commission of the crime, qualified elements of crime and sanctions. The second subchapter, Administrative law, examines three mostly committed minor offences related to the addictive substances in road transport. These are minor offences according to § 125c odst. 1 písm. b), písm. c) and...
