Associations Between Young Children's Problematic Media Use and Physiological Regulation -- Does Temperament Act as a Mediator?

Chojnacki, Noah Alexander 18 April 2024 (has links) (PDF)
Given the ubiquity of media use, especially among young children, the current study examines the impact of problematic media use (PMU) on children's (N = 418, M age = 53.62 months, SD = 3.38 months, M and SD are taken from the full sample of 418 children) physiological functioning. With previous studies reporting relations between media use, temperament, and physiological regulation, it was hypothesized that children with greater levels of PMU would have lower levels of baseline respiratory sinus arrhythmia (RSA; a measure of physiological regulatory capacity). It is further hypothesized that, higher levels of negative affect, and lower levels of effortful control (two distinct domains of temperament) would be linked to both PMU and RSA and that temperament might mediate the associations between PMU and physiological regulation (RSA) (i.e., higher negative affect, lower effortful control linked to higher PMU and lower RSA). Data were drawn from Wave 5 of Project M.E.D.I.A, a longitudinal study of the effects of media on children's development. Findings revealed that PMU was significantly linked to lower baseline RSA for girls, but not for boys. Both boys' and girls' PMU was linked to higher levels of negative affect. Girls' PMU was linked to lower effortful control. The hypothesis that temperament would meditate links between PMU and RSA was not supported. The sex difference in the relation between PMU and baseline RSA are discussed, including potential differences in content of media girls are using as well as potential developmental differences for girls' reactivity compared to boys. Overall, PMU may lead to diminished physiological regulation, especially for girls, and appears to be linked to higher levels of negative affect in children. It is important for parents to be aware of the potential impact media use may have on their children's development.

Närvarofrämjande, förebyggande och åtgärdande arbete gällande problematisk skolfrånvaro : Specialpedagogens insatser beskrivna i 20 kommunala handlingsplaner / Supportive and preventative measures and intervention programs as response to problematic school absenteeism : The special educator’s role as described in 20 municipalities’ action plans

Hellborg, Susanna, Nilsson, Lotta January 2021 (has links)
Problematisk skolfrånvaro har uppmärksammats efter att en statlig utredning 2016 kom fram till att det finns bristande kunskap inom området i Sverige. Studiens syfte är att undersöka hur specialpedagogen används i det främjande arbetet för skolnärvaro och det förebyggande och åtgärdande arbetet vid problematisk skolfrånvaro utifrån 20 kommunala handlingsplaner. Frågorna är: Vilka insatser för närvaro och problematisk skolfrånvaro, som beskrivs i de kommunala handlingsplanerna, kan kopplas till specialpedagogen? På vilka nivåer (individ-, grupp- och organisationsnivå) används specialpedagogen i arbetet med att främja närvaro och att förebygga och åtgärda problematisk skolfrånvaro? En kvalitativ dokumentanalys gjordes utifrån sex kategorier. Systemteori och specialpedagogiska perspektiv användes i analysen för att belysa studiens frågor. Sammanfattningsvis visar studien att specialpedagogen kopplas explicit till uppgifter som till exempel fördjupad kartläggning vid skolfrånvaro och specialpedagogiskt stöd till enskild elev på individnivå. Specialpedagogen nämns implicit genom elevhälsans arbete på organisationsnivå i ett fåtal handlingsplaner.  I diskussionen lyfts varför handlingsplanerna bör uttrycka det främjande och förebyggande arbetet och hur det förebyggande och åtgärdande arbetet kan utvecklas i det systematiska kvalitetsarbetet kopplat till specialpedagogens kompetens. Därutöver diskuteras även den specialpedagogiska kompetensen och dess roll i elevhälsan, riskerna med frånvaroteam och behovet av att utveckla ämnet problematisk skolfrånvaro i den specialpedagogiska utbildningen. / Problematic school absenteeism as first identified as a problem in 2016 when a government inquiry concluded that there was a lack of proper knowledge on the subject in Sweden. The purpose of this paper is to explore how 20 municipalities, via their schools’ action plans and policies, utilize special educators with regard to students’ problematic school absenteeism through the use of early intervention, and preventative and supportive measures. Examined will be: How is the special educator involved in the efforts to curb problematic school absenteeism? On what levels (individual, group or organizational) is the special educator engaged to promote attendance and to prevent and remedy problematic school absenteeism? The observational basis for this paper is a qualitative analysis of action plans from twenty different municipalities. This analysis was made based on six categories. Systems theory and special needs perspectives were used in the analysis to highlight the questions posed in this paper. In summary, the special educator is explicitly connected to certain tasks such as the in-depth tracking of absenteeism and the support for students with special needs. More often, the responsibilities included under the special educator’s purview are implicitly included in the framework for the team responsible for student well-being. The discussion addresses why action plans must describe supportive and preventative measures and ways in which preventive and remedial activities can be developed during systematic quality processes linked to the special educator's skills set. Additionally, discussed were the special educator’s roll in the team responsible for student well-being, the pros and cons with the absenteeism-teams and even the need to develop understanding for this subject in training for the special educator.

Stress, affect systems and eating pathology in problematic weight regulation

Kupeli, Nuriye January 2014 (has links)
Problematic weight regulation as found in obesity and Anorexia Nervosa (AN) are chronic conditions which require long-term management. In order to develop long-term strategies to manage these conditions, a clearer understanding of the factors that can contribute to the development and also recovery from these conditions are a necessity. Although obesity and AN are at the opposite end of the bodyweight spectrum, some shared psychological processes may drive these states. One factor that has been suggested to contribute to problematic weight regulation is psychosocial stress whilst positive affect systems and affect regulation processes are important for regulating stress-related experiences. Gilbert (2005) describes an affect regulation system which consists of two positive affect systems known as social rank and attachment. Whilst the latter affect system refers to the attachment bond that develops between an infant and its caregiver (which extends to adult relationships), the former is used to form relationships that allow us to compete for limited resources and maintain our status in the social environment. Affect regulation processes in the current research are self-criticism and self-reassurance. Whilst self-critical thoughts and feelings can be triggered by perceptions of being low rank, the idea that people can be self-reassuring or being able to self-reassure at times of difficulty is nested in the positive infant-caregiver attachment bond and a consequence of internalizing parental soothing (Gilbert, 2006). Hence, as stress is suggested to be an important factor in problematic weight regulation and affect systems and processes are central to the regulation of emotional responses to stress-related experiences, the current series of studies examined these factors in relation to problematic weight regulation. The current research consisted of four studies designed to examine the role of stress and affect regulation in relation to weight change, weight regain following weight loss and recovery versus symptom maintenance in AN in women. A longitudinal study (Study One) was conducted to examine the change trajectories of stress, eating pathology and bodyweight, how these changes influence each other and the role of affect regulation systems and processes on these changes in a community based sample (N = 1157). Study Two examined the role of stress and affect regulation as predictors of weight regain in those who have lost weight (N = 42) and Study Three used a measure of life events and difficulties to investigate the role of stressful life changes and affect systems on recovery and relapse following AN (N = 30). Finally, in Study four, an expressive writing task which has been demonstrated to have a positive impact on stress-related health outcomes was used to explore the role of stress, affect systems and processes on problematic weight regulation and eating at times of stress (N = 57). The findings of the research studies demonstrated that there is a concurrent link between stress and the regulation of bodyweight and eating in a community-based sample of women. However, the proposed relationship between stress, bodyweight and eating behaviours was not confirmed when examined longitudinally in a community-based sample, over a 7-month period in women who have lost weight or when examined retrospectively as contributing to symptom maintenance in women with AN. However, the main finding of the current series of studies suggested that affect systems and affect regulation processes do have important implications for regulating stress-related experiences, bodyweight and eating behaviours. Perceived low social status, greater insecurity of attachment, more self-critical and less self-reassuring thoughts and feelings were related to increases in stress levels, higher bodyweight and higher levels of dysfunctional eating patterns. In addition, whilst expressive writing did not reduce stress, influence bodyweight or improve affect regulation at times of difficulty, writing about positive experiences had a positive impact on reducing dietary restraint behaviours during a stressful period. In conclusion, these findings suggest that it may not be stress per se that contributes to unhealthy changes in bodyweight and eating behaviours but how we use our affect systems and processes to manage our emotions at times of difficulty. Consequently, these findings have important implications for practice as weight loss programmes, Eating Disorder prevention programmes and stress management interventions should address the issues of perceived low social status, self-criticism and attachment insecurities.

Engagement with Novel Internet Technologies: The Role of Perceived Novelty in the Development of the Deficient Self-Regulation of Internet use and Media Habits

Tokunaga, Robert Shota January 2012 (has links)
This dissertation attempts to expand our understanding of the deficient self-regulation (DSR) of Internet use and media habit development. Drawing from a social cognitive perspective, DSR is described as lapses in effective self-control that are self-corrected over time. A shortcoming in this area of research is that factors relevant to the technology that may encourage the development of DSR or media habits are rarely, if ever, discussed. A large focus of existing research is instead narrowly placed on individual factors that motivate DSR and media habits. An extension is proposed to theory on DSR in this dissertation by examining the role played by novelty perceptions of technology. In the initial stages of technology use, when perceptions of novelty generally grow, perceived novelty is hypothesized to elicit a state of flow, which in turn diminishes the subfunctions of self-regulation and provokes DSR. The relationship between perceived novelty and flow is moderated by psychosocial problems, boredom proneness, and self-reactive outcome expectation. As perceived novelty of a technology decreases, it is presumed that self-control is restored given that flow no longer inhibits self-regulation. However, DSR and media habits are hypothesized to persist in later technology use if individuals experience psychosocial problems, boredom proneness, or high self-reactive outcome expectations. The manifestation of DSR in later stages of technology use increases the likelihood of forming media habits. The influence of novelty perceptions was evaluated on flow, DSR, and media habits at initial and later stages of technology use. The pretest demonstrated that a novelty frame successfully manipulated novelty perceptions of Second Life, the technology used in this experiment, in anticipated directions. In the main study, perceived novelty resulted in flow, which in turn predicted growth of DSR during initial stages of Second Life use. In the familiar stages of use, DSR led to the development of media habits over time; however, the relationship between novelty perceptions and DSR was not moderated by psychosocial problems, boredom proneness, or self-reactive outcome expectation. The findings of this investigation are discussed aside their implications for research, theory, and practice.

Socioekonomický status a problémy se zákonem u problémových uživatelů opioidů a metamfetaminu / Socioeconomic status and criminal problems of problematic opioids and metamphetamine users

Zittová, Lucie January 2017 (has links)
of the thesis Introduction: This dissertation focuses on socioeconomic status and problems with law of problematic opioid and methamphetamine users. Long-term intensive use of drugs leads not only to health impacts, but also social such as the inability of financial autonomy, indebtedness, unemployment, failure to comply with the respective social roles, fiduciary social functioning, poor housing etc. Great number of users are influenced by the drug in situations such as interpersonal relationship, family functioning and partnerships, there is a change of social status, social isolation or exclusion. Effective interventions and service development should always start with a good knowledge of the situation and needs of the user, who claims the service. Claim: The goal of this thesis is finding socioeconomic status and criminal situation of problematic methamphetamine and opioids users consequently draw recommendations towards services that work with these clients. Methods: Cross-sectional questionnaire study was carried among clients who have started a treatment episode or contacted selected facility type such as a contact centre, psychiatric AT ambulance, therapeutic community, medium-term inpatient treatment or replacement therapy. Recruitment into the study took place from June 2015 until October...

Les effets de l’engagement par le brouillon sur des scripteurs au collège / Commitment’s effects by the draft on writers in middle school

Batt, Marie 02 May 2012 (has links)
Lorsqu’un professeur de français incite un élève à produire un brouillon, il cherche en premier lieu à agir sur le comportement du scripteur par la production d’un écrit le menant à opérer une révision de son texte. C’est donc avant tout une action qui est attendue : celle d’un retour sur les écrits se matérialisant sous le trait de ratures. La mise en œuvre d’un brouillon ne s’arrête pas là. Elle touche tout autant les attitudes par une confrontation à un texte qui ne se présente pas sous la forme d’un écrit définitif ou d’une dictée provenant des sources mêmes de l’inspiration, mais comme un travail, une élaboration. Cette étude, à travers la théorie de l’engagement, tente d’approcher les conséquences comportementales et cognitives de la réalisation de brouillons. Pour ce faire, sont analysés via le type de ratures, les brouillons de 253 scripteurs appartenant aux classes de sixième et de troisième. En parallèle, un questionnaire renseigne quant à la manifestation d’effets cognitifs. Les résultats présentent la situation d’engagement, les aspects problématiques soulevés par la rédaction et le brouillon ainsi que les caractéristiques des effets comportementaux et cognitifs en fonction de l’expertise du scripteur. / When a professor of french encourages a student to produce a draft, at first, he looks for to act on the writer’s behavior by producing a writing which leads him to carry out a revision of its text. It is then an action that is expected : the one of a review of the writings which materializes under the stroke of erasures. The purpose of a draft don’t stops here. It concerns as much the writer’s attitudes by facing a text that is not in form of a final writing or a dictation deriving from inspiration’s sources but as a work, as an elaboration. This study, through the commitment theory attempts to cover the behavioral and cognitive consequences linked to the completion of a draft. For that purpose, the analysis based on the kind of the erasures covers the drafts of 253 writers pertaining to the 6th and 3rd classes. Besides, a questionnaire gives information about the appearance of cognitive effects. The results either show the commitment situation, the problematic aspects raised by the redaction and the draft or the behavioral and cognitive effects characteristics depending on the writer’s expertise.

Francová, Olga January 2009 (has links)
The main goal of this thesis is to identify the most problematic area of trade liberalization process within the WTO. The thesis is based on the presumption, that in the WTO context exist three potentially problematic areas - institutional, political and technical. The thesis consists of three chapters. The first chapter discusses institutional framework of the WTO. The second chapter contains analysis of positions and interests of the important member states. It also includes political and economic background of their attitude towards trade liberalization. Special attention is given to the various aspects of the relationship between advanced developing and developed countries. The third chapter is made up of three parts that correspond to the economic sectors and that describe technical aspect of negotiations about sensitive questions of liberalization. In conclusion, state of negotiations is summed up and some presumptions about the future of the negotiations and the WTO are presented.

Addiction à internet : définitions et évaluations / Internet addiction : definition and assessments

Laconi, Stéphanie 18 November 2014 (has links)
L’addiction à Internet a fait l’objet de nombreuses études à travers le monde durant les vingt dernières années. Pourtant aucun consensus au sujet de sa définition ou de ses critères diagnostiques n’a encore été admis, soulevant ainsi de nombreux débats. Ce travail a pour objectif d’étudier la conceptualisation de l’addiction à Internet principalement au travers de ses outils d’évaluation, et de combler un manque de données empiriques au sein d’échantillons français.Étude 1 – Objectif : Déterminer le nombre d’outils de mesure de l’addiction à Internet et mettre en avant leurs qualités psychométriques. Résultats : Quarante-cinq outils mesurant l’addiction à Internet ont été identifiés dont seulement dix-sept ayant été évalués plus d’une fois en termes de propriétés psychométriques. La plupart des échelles existantes nécessitent de plus amples travaux de validation. Bien que critiqué, l’Internet Addiction Test (IAT) est l’échelle présentant le plus de supports empiriques. Cependant, de nombreuses échelles prometteuses requièrent un examen plus approfondi. Étude 2 – Objectif : Évaluer les qualités psychométriques de l’Online Cognition Scale (OCS). Résultats : Les analyses factorielles de l’OCS suggéraient un meilleur ajustement du modèle avec une solution à 5 facteurs (27 items), comparé au modèle original (36 items). Nos résultats mettent en avant une excellente consistance interne et des corrélations inter items et test-retest satisfaisantes. Les scores de l’OCS étaient significativement corrélés avec ceux de l’IAT, du temps passé en ligne et des symptômes dépressifs au cours des deux passations. Étude 3 – Objectifs : Évaluer les qualités psychométriques de la Generalized Problematic Internet Use Scale-2 et la pertinence du modèle d’Utilisation Problématique Généralisée d’Internet (UPGI) au sein d’étudiants français. Résultats : Les résultats de la modélisation en équations structurelles soutiennent ce modèle conceptuel de l’addiction à Internet, et un bon ajustement du modèle aux données. Les qualités psychométriques de la version française de la GPIUS-2 étaient satisfaisantes, notamment la fiabilité, et les validités convergente et concurrente, confirmant l’utilité de cet outil multidimensionnel. Étude 4 – Objectif : Explorer la relation entre l’UPGI et les Utilisations Problématiques Spécifiques d’Internet (UPSI). Résultats : Nos analyses mettent avant des relations significatives entre l’UPGI, les symptômes psychopathologiques et la plupart des UPSI, avec de nombreuses différences en fonction du genre et de l’âge. Alors que les scores d’UPSIcommunication prédisaient ceux d’UPGI chez l’ensemble des participants, ceux d’UPSIrecherche d’informations et jeux en ligne, ainsi que les symptômes dépressifs n’étaient significatifs que chez les femmes, les hommes et les jeunes adultes, et l’UPSIconsommation de vidéo/musique et le temps passé en ligne uniquement chez les femmes et les jeunes adultes. / Internet addiction has been the subject of numerous studies worldwide, during the last twenty years. Yet, no consensus on its definition or diagnosis criteria has been admitted, which therefore is triggering numerous debates. The present research aims to study the conceptualization of Internet addiction mainly through its assessment tools, and to fill in the lack of empirical data among French samples.Study 1 - Aim: To assess the measurement tools for Internet addiction and their psychometric properties. Results: Forty-five tools assessing Internet addiction were identified, of which only seventeen had been evaluated more than once in terms of their psychometric properties. Most of the existing scales for Internet addiction require further validation work. Despite criticism, the Internet Addiction Test (IAT) appears to be the scale with the most empirical support. However, numerous promising scales warrant further examination.Study 2 - Aim: To evaluate the psychometric properties of the Online Cognition Scale (OCS). Results: Confirmatory factorial analyses showed that the 4-factor solution did not demonstrate satisfactory fit but the 5-factor model was found to better fit the data. Our results revealed that the scale scores demonstrated excellent internal consistency and satisfying inter-item correlation and test-retest reliability. The OCS was significantly correlated with the IAT, time spent online and depressive symptoms at both time points.Study 3 - Aim: To evaluate the psychometric properties of the Generalized Problematic Internet Use Scale-2 and the relevance of the Generalized Problematic Internet Use (GPIU) model among French users. Results: Path analysis provided support for this conceptual model of problematic Internet use, and a good fit to the data. The psychometric properties of the French version of the GPIUS-2 were satisfying, including reliability, concurrent and convergent validities, suggesting the usefulness of this multidimensional tool.Study 4 - Aim: To explore the relationship between GPIU and Specific Problematic Internet Uses (SPIU) Results: Our analysis revealed significant relationships between GPIU, psychopathological symptoms and most of SPIU, with many differences according to gender and age. SPIUcommunication scores significantly predict GPIU scores among the whole sample, whereas SPIUinformation seeking and gaming, and depressive symptoms were only significant among women, men and young adults, and SPIUconsumption of video/music and time spent online, among women and young adults.

No. of bitstreams: 1 Anamaria Aguiar e Salles.pdf: 1150702 bytes, checksum: dd9cf50d89097102632f11a215d3f940 (MD5) Previous issue date: 2011-06-07 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / The abolitionist thought redeminishes the criticism of the penal practices from the problematization of the existence of the reality of crime s ontology and of the universality of laws and punishments. In spite of the diversity of the lines of thoughts it interests itself in repairing the victims and to understand the offensors involved in problematic situations. It highlights that each conflictual situation that comes across in a person s life happens in a singular manner and that, thereafter, a problematic event will never be the same as another. Louk Hulsman, from his libertarian perspective proposes the direct conciliation between individuals involved in problematic situations. He understands penal abolitionism as a practice held in the present by refusing the language of the criminal justice system, and the resolution of problematic situations beyond its reach. The wish to affirm the abolitionism, took him travelling around the planet, establishing connections and promoting new ways of thinking from the events he experienced. The dissertation Louk Hulsman and penal abolitionism , intends to show the construction of Louk Hulsman s abolitionism thought and its repercussions, by including Brazil and Argentina, by means of the analysis of the papers produced by the abolitionist and interviews with intellectuals who were close to him. It is interested in tracing the battle waged by the abolitionist thinkers against a system of justice that is selective and reproduces violence, and to show captures and attempts of immobilization of the abolitionist thought in the actuality by incorporating its suggestions on alternative programs of justice / O pensamento abolicionista redimensionou a crítica às práticas penais a partir da problematização da existência da realidade ontológica do crime e do universalismo das leis e dos castigos. Apesar da diversidade nas linhas de pensamento, interessa-se em reparar as vítimas e compreender os infratores envolvidos em situações-problema. Destaca que cada situação conflituosa que atravessa a vida de uma pessoa acontece de maneira singular, e que, portanto, um evento problemático nunca será igual ao outro. Louk Hulsman, a partir de sua perspectiva libertária, propõe a conciliação direta entre os indivíduos envolvidos em situações-problema. Entende o abolicionismo penal enquanto prática que se exerce no presente, pela recusa da linguagem do sistema de justiça criminal, e pela resolução de situações-problema fora de sua esfera. A vontade de afirmar o abolicionismo o levou a viajar pelo planeta, estabelecendo conexões e provocando novos pensamentos a partir dos acontecimentos que vivenciava. Esta dissertação, Louk Hulsman e o abolicionismo penal , pretende mostrar a construção do pensamento abolicionista de Louk Hulsman e suas repercussões, incluindo o Brasil e a Argentina, por meio da análise dos escritos produzidos pelo abolicionista e por entrevistas com intelectuais que lhes foram próximos. Interessa-se em traçar a batalha travada pelos pensadores abolicionistas contra um sistema de justiça seletivo e reprodutor de violências, e em mostrar as capturas e tentativas de imobilização do pensamento abolicionista na atualidade ao incorporar suas sugestões a programas alternativos de justiça
