Researchers have taken a particular interest in children’s drawings as a means of representing and communicating knowledge and perspectives but a review of literature reveals that researchers routinely use drawings as a way of obtaining data without considering their function or value. This ESRC-funded research aims to explore drawing as a method of accessing children's perspectives and has three central research objectives which consider methodological and analytical factors relating to the use of children’s drawings as a research tool. These are: to develop a principled approach to analysing and interpreting children’s drawings, to create guidelines for the use of drawing as a research tool, and to gather children’s perspectives on play through the method of drawing. The research objectives were achieved by asking the following three questions: How can children’s drawings be analysed using a principled approach? What are the major factors to be considered when using drawing as a research tool? What can drawings reveal about children's perspectives on play? The study involved two visits to the homes of eight preschool children aged four. The sample included four girls and four boys from central and north-east Scotland with half of the families being categorised as being of low socioeconomic status. Visits were flexible and unstructured allowing the child autonomy regarding our level of interaction and the types of activities (such as free play and conversation) with which they wished to engage. The second visit included a prompted drawing activity in which I invited children to express their perspectives on play. The topic of play was chosen (i) to offer children a meaningful research activity to investigate the issues surrounding the method, (ii) to explore the task of representing an abstract, yet familiar, concept and how this may influence children’s drawings and representations of play, and (iii) as an extension of the ESRC project Young Children Learning with Toys and Technology at Home (Plowman et al., 2012) by giving greater emphasis to children's own perspectives on play and exploring the ways in which this can be achieved. My theoretical approach is not to consider drawings as reproductions of reality, but to value and attempt to understand children’s drawings as a semiotic vehicle in which messages are created and conveyed during the drawing process through representation and signification. Informed by social semiotics (Kress & van Leeuwen, 1996) the research presents an innovative four-step approach to analysing children's drawings (4-SASA). The protocol, a key contribution of the research, was developed to promote a more systematic analysis, involving (i) isolating signs within drawings through manual annotation, (ii) documenting the child’s understanding of signs and the significance attributed to them, (iii) organising signs using specific categories of social semiotic analysis (mode, size, colour, salience) and identifying the child’s motivation and interest for specific sign production, and (iv) synthesis of the child’s perspectives from steps 1-3. Post hoc methodological examinations elucidated the following four key factors to be considered when using young children’s drawings: (i) contextual sensitivity of the drawing process, (ii) children’s perceptions of the research task, (iii) the complex task of representing an abstract and elusive concept such as play, and (iv) whether there is a fundamental difference between drawing spontaneously (non-commissioned) and drawing on request. Evidence from the study supports previous literature in demonstrating the potential of drawing as a method of accessing children’s perspectives. However, findings suggest that rather than routinely selecting drawing as a method for representing children’s perspectives, researchers need to be more thoughtful about the ways in which factors such as the social and contextual framing of drawing and approaches to data collection can affect research outcomes. The thesis concludes by discussing how these emerging issues impact research outcomes, along with implications for future implementation and analysis of drawings.

Full weighted least squares (full WLS) and robust weighted least squares (robust WLS) are currently the two primary estimation methods designed for structural equation modeling with ordinal observed variables. These methods assume that continuous latent variables were coarsely categorized by the measurement process to yield the observed ordinal variables, and that the model proposed by the researcher pertains to these latent variables rather than to their ordinal manifestations. Previous research has strongly suggested that robust WLS is superior to full WLS when models are correctly specified. Given the realities of applied research, it was critical to examine these methods with misspecified models. This Monte Carlo simulation study examined the performance of full and robust WLS for two-factor, eight-indicator confirmatory factor analytic models that were either correctly specified, overspecified, or misspecified in one of two ways. Seven conditions of five-category indicator distribution shape at four sample sizes were simulated. These design factors were completely crossed for a total of 224 cells. Previously findings of the relative superiority of robust WLS with correctly specified models were replicated, and robust WLS was also found to perform better than full WLS given overspecification or misspecification. Robust WLS parameter estimates were usually more accurate for correct and overspecified models, especially at the smaller sample sizes. In the face of misspecification, full WLS better approximated the correct loading values whereas robust estimates better approximated the correct factor correlation. Robust WLS chi-square values discriminated between correct and misspecified models much better than full WLS values at the two smaller sample sizes. For all four model specifications, robust parameter estimates usually showed lower variability and robust standard errors usually showed lower bias. These findings suggest that robust WLS should likely remain the estimator of choice for applied researchers. Additionally, highly leptokurtic distributions should be avoided when possible. It should also be noted that robust WLS performance was arguably adequate at the sample size of 100 when the indicators were not highly leptokurtic. / text

<p>This manuscript is comprised of three papers that examine the far-reaching and often invisible political outcomes of gender role socialization in the United States. These papers focus primarily on two areas: political confidence amongst girls and women, and the effects of gender on survey measurement and data quality.</p><p>Chapter one focuses on political confidence, and the likelihood that women will run for political office. Women continue to be underrepresented at all levels of political leadership, and their lack of political ambition, relative to men, has been identified as a primary cause. In this paper, I explore the relationship between an individual's masculinity and femininity and her development of political ambition. Using original survey data from the 2012 Cooperative Congressional Election Study (CCES), I first empirically demonstrate that gender (masculinity/femininity) and sex (male/female) are unique elements of identity and, moreover, are both independently related to political ambition. I then explore the relevance of gender for the study of candidate emergence, testing whether and how masculinity and femininity might be related to political ambition are supported empirically. While the results suggest that masculinity is positively associated with the development of political ambition, the relationship between femininity and candidate emergence seems to be more complicated and not what prevailing stereotypes might lead us to expect. Moreover, while the relationship between masculinity and political ambition is the same for men and women, the relationship between femininity and political ambition is very different for women than it is for men. This study suggests that gender role socialization is highly related with both men's and women's desire to seek positions of political leadership.</p><p>Chapter two continues this exploration of gendered differences in the development of political ambition, this time exploring how social attractiveness and gendered perceptions of political leadership impact the desire to hold political office.Women are persistently underrepresented as candidates for public office and remain underrepresented at all levels of government in the United States. Previous literature suggests that the gendered ambition gap, gender socialization, insufficient recruitment, media scrutiny, family responsibilities, modern campaign strategies, and political opportunity structures all contribute to the gender imbalance in pools of officeholders and candidates. To explain women's reticence to run, scholars have offered explanations addressing structural, institutional, and individual-level factors that deter women from becoming candidates, especially for high positions in the U.S. government. This paper examines a previously unexplored factor: how dating and socialized norms of sexual attraction affect political ambition. This study investigates whether young, single, and heterosexual women's desire for male attention and fear of being perceived as unattractive or "too ambitious" present obstacles to running for office. The results of these experiments suggest that social expectations about gender, attraction and sexuality, and political office-holding may contribute to women's reticence to pursue political leadership. Chapter two is a co-authored work and represents the joint efforts of Laura Lazarus Frankel, Shauna Shames, and Nadia Farjood.</p><p>Chapter 3 bridges survey methodology and gender socialization, focusing on how interviewer sex affects survey measurement and data quality. Specifically, this paper examines whether and how matching interviewer and respondent sex affects panel attrition--respondents dropping out of the study after participating in the first wave. While the majority of research on interviewer effects suggests that matching interviewer and respondent characteristics (homophily) yields higher quality data, little work has examined whether this pattern holds true in the area of panel attrition. Using paradata from the General Social Survey (GSS), I explore this question. My analysis reveals that, despite its broader positive effects on data quality, matching interviewer and respondent sex increases likelihood to attrit. Interestingly, this phenomenon only emerges amongst male respondents. However, while assigning female interviewers to male respondents decreases their propensity to attrit, it also increases the likelihood of biased responses on gender related items. These conflicting outcomes represent a tradeoff for scholars and survey researchers, requiring careful consideration of mode, content, and study goals when designing surveys and/or analyzing survey data. The implications of these patterns and areas for further research are discussed.</p><p>Together, these papers illustrate two ways that gender norms are related to political outcomes: they contribute to patterns of candidate emergence and affect the measurement of political attitudes and behaviors.</p> / Dissertation

This thesis presents an empirical investigation into substance use, situational characteristics and sexual outcomes in men who have sex with men (MSM) motivated by the high rates of substance use in MSM; the association between substance use and sexual risk behaviours in MSM; the lack of specific theory addressing relationships between substance use, sexual interactions and social interactions between MSM; and the need for clearer understandings of encounter-level associations with sexual risk. Qualitative metasynthesis. This thesis begins with laying the methodological groundwork for a qualitative metasynthesis that theorises the relationship between substance use and social spaces in MSM, with a particular focus on sexual outcomes. The qualitative metasynthesis derives the key organising perspective of ‘littoral spaces’ in which substance use is associated with a pre-planned, though temporary, escape from the boundaries of everyday life to engage in maximal sensory exploration, including through sexual contact. <b>Systematic review of multiple-event analyses. The thesis then turns to a systematic review of previous quantitative multiple-event analyses examining associations between situational characteristics and sexual outcomes, which establishes the need for additional multiple-event analyses addressing specific substance use, location of sex, partner serodiscordance and partner type. Multiple-event analyses. Finally, informed by the qualitative metasynthesis and the systematic review of event-level analyses, this thesis presents multiple-event analyses addressing unprotected anal intercourse (UAI), pleasure and control as sexual outcomes in MSM in England. These analyses found that substance use was associated with greater odds of UAI and pleasure, but not with control, and that non-private locations of sex were associated with decreased odds of UAI and pleasure, but not control. Furthermore, there was sparse evidence of interactions between respondent and partner substance use and between respondent substance use and location of sex in associations with sexual outcomes. These analyses contribute to understandings of associations between substance use, situational characteristics and sexual risk behaviour by presenting the first known analyses on MSM in England and by examining sexual outcomes besides UAI.

The objective of the study was to map the structure of the construction engineering and management (CEM) discipline and its contents, trace its evolution, and to identify the most prevailing research areas in the discipline. The study entailed a review of the literature in construction engineering and management as well as two of the leading academic journals in the discipline, particularly a bibliometric study of the contents of the ASCE Journal of Management in Engineering (JME), as a case study of the CEM refereed journals. The JME's contents were investigated from its onset in 1985 until 2002. The results of the analysis show that 70% of the published papers focused on four main subjects: management and organization of the firm, project management, industry structure and environment, and management of personnel. Considerable changes occurred within the subjects with the emergence of new topics and the decline of others over the eighteen years of publication. The study also analyzed the use of keywords, research methods, and identified authors, and the concentration of knowledge. The JME is mainly concerned with the managerial aspects of engineering, while ASCE Journal of Construction Engineering and Management (JCEM) focuses more on construction and technical issues. Additional studies of the JCEM's contents should be conducted for a complete mapping of the discipline in the USA.

<p>This was a descriptive qualitative study. Eight people living with HIV, four of which had disclosed their status, were individually interviewed. Two focus group discussions (each comprising 6 participants) were also conducted with health workers. The study was based at an urban TB hospital which is currently providing a range of HIV-related services including HIV Voluntary Counselling and Testing, case management and treatment.</p>

This field study presents mobile rescue robots as a way of augmenting communication in distributed teams through a remote shared visual presence (RSVP) consisting of the robot's view. It examines the effects of RSVP on team mental models, team processes, and team performance in collocated and distributed Urban Search & Rescue (US&R) technical search teams, and tests two models of team performance. Participants (n=50) were US&R task force personnel drawn from high-fidelity training exercises held in California (2004) and New Jersey (2005). Data were collected from the 25 dyadic teams as they performed a 2 x 2 repeated measures search task entailing robot-assisted search in a confined space rubble pile. Team communication was analyzed using the Robot-Assisted Search and Rescue coding scheme (RASAR-CS). Team mental models were measured through a team-constructed map of the search process. Ratings of team processes (communication, support, leadership, and situation awareness) were made by onsite observers, and team performance was measured by number of victims (mannequins) found. Multilevel regression analyses were used to predict team mental models, team process, and team performance based upon use of RSVP (RSVP or no-RSVP) and location of team members (distributed or collocated). Results indicated that the use of RSVP technology predicted team performance (Ã?=-1.322, p = 0.05), but not team mental models or team process. Location predicted team mental models (Ã?=-0.425, p = 0.05), but not as expected. Distributed teams had richer team mental models as measured by map ratings. No significant differences emerged between collocated and distributed teams in team process or team performance. Findings suggest RSVP may enhance team performance in US&R search tasks. However, results are complicated by differences detected between sites. Support was found for both models of team performance, but neither model was found sufficient to describe the data. Further research is suggested in the use of RSVP technology, the exploration of team mental models, and refinement of a modified model of team performance in extreme environments.

SUMMARY Topic of Investigation: Socio-Educational Discourse of Children Summer Holidays (as a kind of leisure and recreation forms). Author of the Work: Ruta Palubaityte, student of Educology Program of Studies EMM-03 (specialization: leisure pedagogy and basics of recreation) Siauliai University, Educology Faculty. Urgency of the work. According to the data of the State Youth Affairs Council (2004), “having much leisure” if the most important feature of the youth. One fifth of the interviewed youths maintain such opinion.However almost every seventh young person (15 per cent) state they are too little occupied and have too much leisure, almost every sixth (17 per cent) noted lack of occupation as youth’s problem.Most of the (over 65 per cent) 14-29 aged youths spends leisure watching TV, meeting friends or listening music. Large part of their leisure is spent for chores, work with PC or Internet and sports (http://www.vjrt.lt/apie_jaunima/laisvalaikis). Most of the data covers leisure of the teenagers and youths. There is no generalized statistics about leisure of the children (preschool and school-aged) in Lithuania. Children leisure camp attendance reports are the only available sources. However information, covering another leisure forms, is lacking. In Lithuania only children leisure forms and methods undergo analysis. Subject of Investigation: Socio-Educational Significance Discourse of Children and Adults Summer Holidays. Target of the Work: the work is aimed to... [to full text]

We assessed how estimates of need-expected inpatient hospital use differ depending on whether need-expected use was estimated for a population of all Canadians, Canadian health regions, or a subpopulation of higher income Canadians, who likely had minimal healthcare access problems. Data came from the 2009/2010 Canadian Community Health Survey, a national cross-sectional survey. Using zero-inflated negative binomial regression, we modeled inpatient hospital use separately based on the three aforementioned choices of population. We adjusted for demographic, health behaviour, health status, socioeconomic, and health care supply factors. We then estimated need-expected inpatient hospital use and compared the estimates across individuals and by income and province. The three choices of population that we used in this study had similar results. Our estimates of the average need-expected use by province or income group were not sensitive to the choice of population used to estimate need-expected use.
