Magister Scientiae Dentium - MSc(Dent) / Introduction: Improvement of aesthetics is often the reason patients seek orthodontic treatment. The ability to accurately assess aesthetic treatment need from the viewpoint of the patient is necessary. The threshold for orthodontic treatment is not constant in all countries and no previous attempts to determine this threshold has been made in South Africa. By ensuring that patient’s perceptions of treatment need are incorporated into the index chosen to assess perceived need, accurate data can be obtained. Determining perceived need from the patient’s viewpoint is important, and understanding its relationship with perceived need according to the professional, as well as normative need can facilitate better patient communication and management of expectations. Aims: There were three main aims of this study. First, South African children’s perceptions of treatment need according to the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) was assessed to determine if they were similar to those of the dentists who established the threshold, or if the threshold of the grading system should be altered to better suit laypeople’s opinions. Second, the newly established threshold could then be used to determine the perceived needs for orthodontic treatment, and compare them to the normative need of the population. Finally, factors that may influence the perceived needs of the patients such as gender, ethnicity and socio-economic position could be investigated. Methodology: A cross-sectional study on 317 children aged between 11 and 14 years was done. 43.8% were male and 56.2 % were female. The sample was chosen from five schools in the Lekwa District of Mpumalanga using a multi-stage sampling technique. The study population comprised of four groups based on ethnicity; Asian (3%), black (74%), coloured (6%) and white (17%). The socio-economic position (SEP) was determined by Principal Component Analysis of household assets. Societal perceived, subjective perceived and self-perceived needs were assessed using a questionnaire and the child-rated AC of the IOTN. An intra-oral examination was conducted using the AC of the IOTN to assess objective perceived need and the modified Dental Health Component (DHC) of the IOTN to assess normative treatment need. Results: Treatment threshold was determined to be grade 3 of the AC of the IOTN according to societal perceived need of the group of South African children, and was confirmed by self-perceived need. Subjective perceived need for treatment was assessed using the AC grade participants felt best reflected their aesthetic impairment, and was found to be 20.2%, compared to actual self-perceived need of 38.5%. The latter was deduced by comparing the child-rated AC (subjective perceived need) to their perception of treatment need of that grade (societal perceived need). The objective perceived need measured by the examiner-rated AC was 60%. Definite need for orthodontic treatment based on the modified DHC of the IOTN was 41.2%. No significant difference between societal perceived or self-perceived need and gender or socio-economic position was found. White children have lower societal perceived treatment need regarding others’ aesthetic impairment. Conclusion: The treatment threshold grade should be lowered to better represent the societal perceived and self-perceived need of the South African population. Normative need was higher than perceived needs from the patients’ point of view (subjective perceived and self-perceived need), but lower than the perceived need from the professional’s point of view (objective perceived need). Ethnicity was found to have an influence on societal perceived need.

Trata-se de dissertação de mestrado onde se procura dialogar com os autores que elaboraram diversas teorias do desenvolvimento econômico bem como de desenvolvimento da ciência. Para tanto, toma-se o tema do desenvolvimento ferroviário tal como visto por um estudioso que lhe foi contemporâneo, Adolpho Augusto Pinto, como estudo de caso para aquele diálogo. / Most authors have written about economic and scientific development. In this essay, we dialogue with some of them to compress it better. For that, we take the railway development in estate of São Paulo, as it was seen by another author, Adolpho Augusto Pinto, as a theme for that discussion.

This thesis contributes to the debate on the link between a transitive verb corresponding to 'need' and the verb of possession in the world’s languages. Specifically, I analyze data mainly from Ewe and three Ghana-Togo Mountain (GTM) languages; Likpe, Tafi, and Logba. First, I report that Ewe expresses predicative possession using a wide range of structures. Prominent among these structures is an intransitive locative construction in which the possessee c-commands the possessor. This characterization situates Ewe in the B-languages group of the have/be dichotomy. Second, I demonstrate, drawing on compelling pieces of evidence from object shift in nominalization, object shift in inceptive aspectual constructions, object extraction in wh-movement, and the nominative-accusative paradigm, that Ewe has a transitive verb 'hiã' corresponding to 'need'. These facts pose a challenge to Harves and Kayne’s (2012) claim that all languages that have a transitive verb corresponding to need are languages that have an accusative-Case-assigning verb of possession. Third, I have shown that predicative possessees are not licensed in like manner as transitive objects, contra Halpert and Diercks’ (2012) prediction that all languages that have a transitive verb corresponding to 'need' are languages in which predicative possessees are licensed in the same manner as transitive objects. Fourth, I show that data from the three GTM languages also pose a challenge to the predictions in Harves & Kayne (2012) and Halpert & Diercks (2016). Finally, I suggest that the presence or absence of a transitive verb corresponding to 'need' is not necessarily contingent on a transitive verb of possession, and therefore, the optionality of a transitive 'need' in H-languages should be extended to B-languages.

This dissertation concerns the relationship between the symptomatology of depression and cognition. The purpose of this study was to investigate the assumptions of Beck's negative cognition theory regarding the relationship between patients' lack of ability to reason and depression. Beck noticed that people with depression failed to consciously examine the basis upon which their negative self-defeating reality is founded. This study examined a relationship between critical thinking skills and the need for cognition (the desire to think about ambiguous information) and levels of depression and education. The participants were 75 postsecondary undergraduate and graduate students from both online and traditional universities. This study used two-way between ANOVAs. The participants completed the Zung Self-Rating Depression scale and the Need for Cognition scale, as well as the Ennis-Weir Critical Thinking Essay test. The findings showed no significant differences in scores between those with symptoms of depression and those without in terms of critical thinking skills and need for cognition. A reanalysis was performed to remove outliers in the data, which resulted in finding significant differences between education level and the need for cognition. These findings may suggest that the participants' desire to apply effort to thinking about ambiguous information or problems is related to education level. These findings might help promote positive social change by suggesting that other researchers examine the relationship between critical thinking skills and depression to add to this conversation.

The demand for customised products that meet different markets and different customers is steadily increasing. Also, the demand for shorter lead times for the delivery of these customised products puts strains on design departments whose work tends to become increasingly repetitive. At the same time, designing variants takes time from innovative, original design, and/or problem-solving tasks. A powerful tool in the endeavour to cut lead times, workloads, and ultimately costs in order to become more competitive in an increasingly globalised market is Design Automation. Automating tedious and repetitive design tasks will free the designers to focus on the tasks that require skill, creativity, intuition, and cooperation to be solved. Consequently, seeing a need for design automation systems is not difficult. What becomes a lot more difficult is identifying the type, scope, and format of the system implementation, as well as the actual design tasks and activities to support or automate. Therefore, there is a need for structured and systematic approaches for the realisation and implementation of design automation systems. This research work is aimed at presenting such approaches, methods, and aids. It also addresses the importance of identifying the exact tasks to be automated. This has to be done in order to find the method and implementations best suited for solving the tasks, something that is especially important for companies whose human and financial resources might not allow them to invest in a system with functionality that vastly exceeds their actual needs. The contribution of this work is a structured method for planning for design automation implementation. First, the design process is discussed from an automation perspective. Following this is a presentation of a framework of design automation. This framework has the purpose of serving as a common base for consensual discussions about design automation. In addition, it supports the setting-up of system specifications. The framework is followed by the introduction of a set of identifiers of system needs and potentials, focusing on the existing processes that need to be broken down and identified in order to specify the tasks to be automated. Following this is a set of criteria of system characteristics, focusing on properties of the intended system implementation. Finally, some realisation and implementation issues are addressed and exemplified through a number of pilot system implementations. The presented method for planning design automation, together with the presented framework of design automation, provides implementers with issues to address regarding potential, need, scope, and format of system implementations. Further, it supports the weighing of desired system characteristics in order to find the right balance between system complexity and functionality.

We carry objects from place to place in bags, all the while maintaining that they are trivial objects. If we categorize objects as mundane, then why do we carry them everywhere we go? I interviewed female students at the Claremont Colleges about what they carry in their bags. College women articulate many distinct reasons for carrying a bag and for carrying the items within that bag. My participants perceive the items they carry as mundane, and do not question the presence of those items in their lives. Yet they also claim to need the items they categorize as trivial. They perceive the need to carry items as natural, and so do not question that need. My project demonstrates the ways college women make objects seem trivial and make needs seem natural. Through ethnographic interviews, I highlight how things perceived as mundane have significance. Additionally, I show that carrying a bag and carrying objects enables college women to be prepared to care for the well-being of themselves and the people around them. Between perceptions of objects as inessential and perceptions of the functions of objects as superficial, college women find value in carrying items.

The first objective was to test the prospective relationship between need satisfaction and coping. A total of 113 undergraduate students completed a measure of need satisfaction at Time 1 (T1; i.e. a few weeks before the midterm exams) as well as a measure of coping at Time 2 (T2; i.e. a few weeks after the midterm exams). Results indicated that need satisfaction T1 explained unique variance in both dimensions of coping T2, namely task-oriented and disengagement-oriented coping, even after having statistically controlled for gender, Conscientiousness, Neuroticism, and social desirability at T1. The second objective was to examine a model in which need satisfaction and coping predict the amount of progress towards academic goals and, in turn, how coping and goal progress are associated to increases in need satisfaction over the course of a semester. A total of 166 undergraduate students completed a measure of need satisfaction at Time 1 (T1; i.e. a few weeks before the midterm exams) as well as measures of coping, goal progress, and need satisfaction at Time 2 (T2; i.e. a few weeks after the midterm exams). Results from structural equation modeling indicated that coping T2 fully mediated the relationship between need satisfaction T1 and goal progress T2. Results also indicated that goal progress T2 partially mediated the relation between task-oriented coping T2 and need satisfaction T2 as well as between disengagement-oriented coping T2 and need satisfaction T2.
