Parent-Child Interaction Therapy is a probably efficacious, evidenced-based treatment, which has been proven to decrease problem behaviors of children, as well as improve parent-child interactions. The first phase is the Child-Directed Interaction (CDI), which allows the child to lead the play session, while parents are taught to interact without giving demands, asking questions, or providing criticism. According to the DSM-IV-TR, Reactive Attachment Disorder is a rare diagnosis. Many attachment therapists indicate that traditional approaches to treatment have not been demonstrated as being effective with these children. This study will examine the CDI phase of Parent- Child Interaction Therapy as a potential treatment option for children diagnosed with Reactive Attachment Disorder.

This study focused on the teacher interpersonal behaviour in the teaching of Mathematics, compared to English. It investigated: differences between student perceptions of their Mathematics and English teachers' interaction styles using the actual and ideal QTI; investigate associations between students' attitudes to Mathematics and English and their perceptions of the teachers' interpersonal behaviour; investigate whether any factors exist that contribute to students' perceptions of teachers' interpersonal behaviour, determine what the typical Mathematics and English teacher in Singapore is like; and what makes an effective teacher from students' and teachers' viewpoints. The QTI, together with the Attitude to Mathematics and Attitude to English, was administered to 913 students and 37 mathematics and English teachers from an independent school in Singapore. Student and teacher interviews were conducted to further substantiate the quantitative results. Both QTI and attitudinal scales were found to be valid and reliable instruments with alpha coefficients ranging from 0.69 to 0.92. In terms of leadership, helping/friendly, understanding and student responsibility, teacher behaviour as perceived by students, fell short of the ideal. Positive associations were found between students' attitudes to Mathematics and English and their perceptions of the teachers' interpersonal behaviour. Teacher experience and students' grade level were factors that contributed to students' perceptions of teachers' interpersonal behaviour. The typical Singaporean Mathematics teacher is that of the directive and authoritative type and the English teacher is the tolerant-authoritative type. Finally, an effective teacher is one who, besides having the positive qualities of good leadership, helping/friendly, understanding, has a good sense of humour and a passion to make a difference.

This study discusses sorne assumptions from the social determinism in the construction of gender roles, gender-typed identities, and gender relarions inequities. Ir is proposed that gender sryles of interaction are relatively invariant forms or dispositions related ro specific contexts of social interaction. Iris not enough ro say that socialization factors such as the family, school, mass media, and rhe inirial social group relations generare a typed gender identity or gender seggregation, but it is also necessary ro make explicit how preferences, beliefs and interaction sryles are structured according ro rhose factors and how these interactive tendencies are built u pon social interaction situations as part of a developmental process. / En el presente trabajo se discuten algunos supuestos del determinismo social en la construcción de roles de género e identidades genéricas estereotipadas y de desigualdad en las relaciones intergéneros. Se propone que los estilos de interacción de los géneros se constituyen como formas o disposiciones relativamente invariantes en relación a contextos particulares de interacción social. No es suficiente afirmar que los factores de socialización y las primeras relaciones en grupo social, generan una identidad genérica estereotipada o de segregación de géneros, sino que es necesario también explicitar el cómo se estructuran preferencias, creencias y estilos de interacción de acuerdo a tales factores y, cómo estas tendencias interactivas se constituyen a partir de situaciones de interacción social y como proceso de desarrollo.

O presente estudo investigou a relação entre as metas de socialização maternas e os estilos de interação mãe-bebê, no primeiro e segundo ano de vida da criança, bem como eventuais mudanças longitudinais neste período. Além disto, investigou-se a relação entre características maternas (ex. idade e escolaridade) e do bebê (ex. sexo e desenvolvimento infantil) e as metas de socialização e os estilos de interação mãe-bebê, durante o mesmo período. Participaram 25 mães (M=33,2 anos; DP=5,73) e seus filhos, que no início do estudo estavam no primeiro ano de vida (M=6,7 meses; DP=1,74). As mães responderam a uma entrevista sobre suas metas de socialização e as díades foram observadas durante interação livre visando examinar seus estilos de interação. O desenvolvimento dos bebês foi avaliado através das Escalas Bayley III. No segundo ano de vida dos bebês, esses procedimentos de coleta de dados foram repetidos. Os resultados apoiaram parcialmente a hipótese inicial de que, independente da idade do bebê, metas de socialização que enfatizam a autonomia estariam relacionadas a um estilo de interação focalizado na autonomia do bebê; e metas de socialização que enfatizam a “relação” estariam relacionadas a um estilo de interação focalizado no direcionamento materno. Somente no primeiro ano do bebê, correlações significativas entre metas de socialização e estilos de interação mãe-bebê foram na direção esperada. Por outro lado, os resultados corroboraram a hipótese de que características maternas e do bebê estariam mais relacionadas aos estilos de interação mãe-bebê do que às metas de socialização, tendo em vista que estas últimas representam valores culturais mais amplos, enquanto os estilos de interação são mais dependentes de fatores contextuais e individuais envolvendo a própria díade mãe-bebê. O sexo do bebê foi a única variável que se relacionou às metas de socialização, mas só no primeiro ano. Por sua vez, diversas características da mãe e do bebê relacionaram-se aos estilos de interação, tanto no primeiro quanto no segundo ano do bebê. Juntos, os resultados do presente estudo ressaltam as limitações de pressupostos lineares e unidirecionais sobre a relação entre metas e estilos de interação, que ainda são destacados na literatura, mas precisam ser superados. Como foi evidenciado, diversos fatores possivelmente permeiam esta relação, com destaque para características da díade mãe-bebê ao longo do processo de desenvolvimento. / The present study investigated the relationship between maternal socialization goals and mother-infant interaction styles in the first and second year of the child's life, as well as possible longitudinal changes in this period. Furthermore, I studied the relations among maternal (eg. age and education) and infant (eg. gender and child development) characteristics and socialization goals and mother-infant interaction styles during the same period. Twenty five mothers (M=33,2 anos; SD=5,73) and their children participated in the study; the latter, at the beginning of study, were in their first year of life (M=6,7 meses; DP=1,74). Mothers were interviewed about their socialization goals and the dyads were observed during free interaction with the aim of examining their interaction styles. The infants’ development was assessed by Bayley Scales III. In the second year of the infants’ life, these data collecting procedures were repeated. The results partially supported the initial hypothesis that, regardless of the infant’s age, socialization goals that emphasize autonomy would be related to an interaction style focused on his or her autonomy, and socialization goals that emphasize relatedness would be are related to an interaction style focused on maternal directives. In the infant’s first year (although not the second) significant correlations between socialization goals and mother-infant interaction styles were in the expected direction. Moreover, the results supported the hypothesis that maternal and infant characteristics would be more related to mother-infant interaction styles than to the socialization goals, considering that the latter represent broader cultural values, whereas interaction styles are more dependent on contextual and individual factors involving the mother-infant dyad. The infant's gender was the only variable that was related to the socialization goals, but only in the first year. By contrast, several characteristics of the mother and infant were related to interaction styles, either in the first or second year of the infant. Together, the results of the present study highlight the limitations of linear and unidirectional assumptions about the relationship between goals and interaction styles, which are still emphasized in the literature, but need to be overcome. As evidenced, several factors probably underlie this relationship, especially characteristics of the mother-infant dyad throughout the development process.

This research examines situated behaviours and perceptions around textual navigation as it is practiced in situ by professionals working in various domains. In its investigation of interactions between human cognition and mediating artifacts, this research relies heavily on the resources of cognitive ethnography, including both observation and in-depth interviews with participants. Relevant contributions from the fields of information studies, book history, digital humanities, and human-computer interaction are presented to further elucidate the findings of this study. The findings reveal several emergent, interrelated navigational strategies, such as the use of annotations as navigational aids, reliance on automated interface actions, and the navigational value of interface metaphors. In further addressing the practice of textual navigation, this research also describes the creation of a prototype interface reflecting the study’s findings. This research proposes new ways of conceptualizing textual navigation and designing interfaces that support emergent textual interaction.

As increasingly large displays are integrated into personal workspaces, mouse-based interaction becomes more problematic. Users must repeatedly "clutch" the mouse for long distance movements [61]. The visibility of the cursor is also problematic in large screens, since the percentage of the screen space that the cursor takes from the whole display gets smaller. We test multi-scale approaches to mouse interaction that utilize dynamic speed and size techniques to grow the cursor larger and faster for long movements. Using Fitts' Law methods, we experimentally compare different implementations to optimize the mouse design for large displays and to test how they scale to large displays. We also compare them to techniques that integrate absolute pointing with head tracking. Results indicate that with some implementation level modifications the mouse device can scale well up to even a 100 megapixel display with lower mean movement times as compared to integrating absolute pointing techniques to mouse input while maintaining fast performance of the typical mouse configuration on small screens for short distance movements. Designs that have multiple acceleration levels and 4x maximum acceleration reduced average number of clutching to less than one per task in a 100 megapixel display. Dynamic size cursors statistically improve pointing performance. Results also indicated that dynamic speed transitions should be as smooth as possible without steps of more than 2x increase in speed. / Master of Science

While there are powerful keyword search systems that index all kinds of resources including emails and web pages, people have trouble recalling semantic facts such as the name, location, edit dates and keywords that uniquely identifies resources in their personal repositories. Reusing information exasperates this problem. A rarely used approach is to leverage episodic memory of file provenance. Provenance is traditionally defined as "the history of ownership of a valued object". In terms of documents, we consider not only the ownership, but also the operations performed on the document, especially those that related it to other people, events, or resources. This thesis investigates the potential advantages of using provenance data in desktop search, and consists of two manuscripts. First, a numerical analysis using field data from a longitudinal study shows that provenance information can effectively be used to identify files and resources in realistic repositories. We introduce the Leyline, the first provenance-based search system that supports dynamic relations between files and resources such as copy/paste, save as, file rename. The Leyline allows users to search by drawing search queries as graphs in a sketchpad. The Leyline overlays provenance information that may help users identify targets or explore information flow. A limited controlled experiment showed that this approach is feasible in terms of time and effort. Second, we explore the design of the Leyline, compare it to previous provenance-based desktop search systems, including their underlying assumptions and focus, search coverage and flexibility, and features and limitations. / Graduation date: 2012
