Abstract:
My research topic concerns how learners use the analogue clock (as a human tool) to make meaning of clock time. This study is informed by a Vygotskian socio-cultural framework to learning and development based on the concept that human activities take place in cultural contexts and is mediated by tools. In this qualitative study I report on the learners meaning making of analogue clock time using the physical clock. This study was carried out at a South African primary school through an intervention programme after school. The research employed a case study method. It involved a purposeful sample of 4 learners (n=38) from the grade four class group based on their response to a baseline assessment task. The selected sample of learners included learners across the ability spectrum to gain rich insight into how learners make meaning of analogue clock time. Data collection and analysis was done through an interpretive approach. The video-taped interviews and intervention programme was my main instrument of data collection. Other research instruments included document analysis of responses to baseline assessment tasks. These research tools yielded the data collected and also allowed for triangulation. My research topic explored how the learners make meaning of analogue clock time. In particular the two-way movement of how the learners use the physical tool namely the analogue clock to develop meaning and how the clock mediates clock knowledge in return. The findings of the study suggest that learners’ find it difficult to conceptualise analogue clock symbols and signs, in particular, in Afrikaans the half hour concept, in relation to the two hands. The physical analogue clock is also important to support and extend clock knowledge in solving time-related problems. This shows the power of the analogue clock to mediate meaning making of clock time in young learners. Because of its potential to improve teaching and learning analogue clock time in primary school it is therefore recommended that the analogue clock time be further researched in South Africa.

O relógio inteligente é um novo tipo de eletrônico para o punho com funcionalidades idênticas as de um celular, que também é utilizado por motoristas durante a tarefa de condução do veículo, representando uma nova forma de distração do motorista, e risco aumentado de acidentes no trânsito; uma demanda da ergonomia cognitiva. O objetivo do presente estudo foi determinar o efeito do uso de relógio inteligente sobre motoristas experientes e novatos durante a condução simulada de automóvel, na tarefa de seguir o automóvel à frente, através da análise de movimento dos olhos, da cabeça e do desempenho na condução. Vinte motoristas experientes (EXP) e vinte motoristas novatos (NOV) realizaram a tarefa de seguir um carro à frente por um percurso de 2 km em quatro condições: somente seguir o carro (CAR), seguir o carro e receber uma notificação de texto no relógio inteligente (NOT), seguir o carro que freará de modo inesperado e brusco (FRE) e seguir o carro que freará de modo inesperado e brusco e, adicionalmente, receber uma notificação de texto (FNOT). Os dados do olhar, da cabeça e do desempenho na condução do automóvel foram submetidos à análise de variância de grupo (EXP, NOV) por condição de freada (CAR, FRE) por condição de notificação (NOT, FNOT) por tentativa (1, 2, 3). O desempenho da condução de veículo foi afetado pela freada do carro à frente e pelo uso do relógio inteligente ao receber notificação. Ao receber uma notificação no relógio, mudava-se o foco atencional do trânsito para realizar a leitura de texto, aumentando as chances de ocorrência de acidente. Experientes e novatos apresentaram diferentes estratégias para viabilizar a leitura do texto no relógio; experientes mostraram-se mais eficientes, mas ambos grupos desviaram o olhar da pista em detrimento da atenção, o que resultou em condição de risco.
Smartwatch is a new kind of electronic to be worn on the wrist with features similar to those of mobile phones, they are also being used by drivers during their driving task, representing a new form of distraction for drivers and increasing chances of traffic accidents. The goal of this project is to determine the use effect of smartwatches on experienced and novice drivers while driving on a simulated driving task following a vehicle ahead, through the analysis of eye and head movement and driving performance in a driving simulator. Twenty experienced drivers (EXP) and twenty novice drivers (NOV) will follow a car ahead for 2 kilometers in four conditions: follow a car ahead (CAR), follow a car ahead and receive a text message notification on the smartwatch (NOT), follow a car ahead that brakes abruptly (FRE) and follow a car ahead and receive a text message notification on the smartwatch while the car ahead brakes abruptly (FNOT). The gaze, head movement and driving performance data will be subjected to group variance analysis (EXP, NOV), with or without braking (CAR, FRE), with or without smartwatch notification (NOT, FNOT) and by trial (1, 2, 3). The diver’s performance showed to be affected by the car’s ahead braking and by the use of smartwatch during reading tasks. Attentional focus was shifted away from the road to the smartwatch when drivers tried to perform the reading task, thus increasing the chances of an accident. Experienced and novice drivers used different strategies to perform the reading task while driving; experienced drivers were more efficient but both groups shifted their gaze away from the road in detriment of their attention to the traffic, which resulted in risk conditions.

Gentry, Karen Lee. "The Forgiveness Project." Digital Archive @ GSU, 2010. http://digitalarchive.gsu.edu/english_theses/81.

Full text
Abstract:
The Forgiveness Project includes a critical introduction that defines the author’s approach to the short-short form as well as an explanation of how historiographical metafiction can work to memorialize. The first section contains primarily short-short stories that address the themes of motherhood, small tyrannies, happy liars, caregiving and the clichés of grief. A collection of linked short stories follows, revolving around elusive forgiveness. On the night of July 17, 1977, Juanita Lee, a bridge tender in South Florida, was abducted by two men and executed in the Everglades to silence her opposition to the demolition of an Intracoastal Waterway bridge. Twenty-two years later her daughter, Jill, now a Washington D.C. lobbyist who views the world through the cynical lens of her life’s work, is confronted with a plea for forgiveness via an organization called “The Forgiveness Project,” representing one of her mother’s killers.

Full text
Abstract:
This study uses the Tibetan mandala, a Buddhist meditation aid and sacred artform, as a secular critical model by which to analyse the complete fictions of author David Mitchell. Discussing his novels, short stories and libretti, this study maps the author's fictions as an interconnected world-system whose re-evaluation of secular belief in galvanising compassionate ethical action is revealed by a critical comparison with the mandala's methods of world-building. Using the mandala as an interpretive tool to critique the author's Buddhist influences, this thesis reads the mandala as a metaphysical map, a fitting medium for mapping the author's ethical worldview. The introduction evaluates critical structures already suggested to describe the author's worlds, and introduces the mandala as an alternative which more fully addresses Mitchell's fictional terrain. Chapter I investigates the mandala's cartographic properties, mapping Mitchell's short stories as integral islandic narratives within his fictional world which, combined, re-evaluate the role of secular belief in galvanising positive ethical action. Chapter II discusses the Tibetan sand mandala in diaspora as a form of performance when created for unfamiliar audiences, reading its cross-cultural deployment in parallel with the regenerative approaches to tragedy in the author's libretti Wake and Sunken Garden. Chapter III identifies Mitchell's use of reincarnation as a form of non-linear temporality that advocates future-facing ethical action in the face of humanitarian crises, reading the reincarnated Marinus as a form of secular bodhisattva. Chapter IV deconstructs the mandala to address its theoretical limitations, identifying the panopticon as its sinister counterpart, and analysing its effects in number9dream. Chapter V shifts this study's use of the mandala from interpretive tool to emerging category, identifying the transferrable traits that form the emerging category of mandalic literature within other post-secular contemporary fictions, discussing works by Michael Ondaatje, Ali Smith, Yann Martel, Will Self, and Margaret Atwood.

Abstract:
M.B.A.
Increased environmental pressure in a firms' local market are forcing many companies to consider markets outside of their own to do maximize their profitability. According to Henisz (2000) when expanding internationally, a firm's management often must contend with a new culture, a new language, a new social system, new market structures, and a new political system. Titan, a premier brand in the Indian sub-continent aspires to assess the Gulf Cooperation Countries (GCC) market for watches. Despite global market recessionary trends, the luxury watch market in the GCC reflects a constant thirty percent increase in business over the previous year, as measured on a monthly comparative basis. The research will indicate that Titan cannot simply apply the local strategies used in India, as this global market possesses different characteristics to those experienced in the GCC, the importance if brand utility may provide a distinct differential over the major competitors in this market. Though the model that is derived will be based on the Titan experience, it will also be applicable to other items in the luxury goods market, and may be utilised to facilitate market entry for all luxury goods which will be categorised in the same band as watches, examples of these include fashion accessories, sunglasses, perfumes and jewellery. The aim of the study was to develop a model to guide the market entry process for new watch brands under the Titan umbrella into the GCC market.

"A study on the dynamics of periodical impact mechanism with an application in mechanical watch escapement." Thesis, 2008. http://library.cuhk.edu.hk/record=b6074686.

Full text
Abstract:
Among various non-smooth dynamic systems, the periodically forced oscillation system with impact is perhaps the most common in engineering applications. Usually it has an oscillator with fixed or unfixed stops. The dynamics becomes complicate due to the impact against the stops. Sometimes it leads to bifurcation and even turns to chaos. Its present applications include MEMS switch device, escapement in watch movement and so on.
As a branch of mechanics, the multi-body dynamic system is well-studied. In particular, the non-smooth dynamical system attracts many researchers because of its importance and diversity. The main behaviours of such a system include contact (slip-stick motion), friction and impact. Although various models have been developed for these behaviours and their results are often satisfactory, the truth is that they are still far from completion. In the past twenty some years, various new methods have been developed. However, none of them is universally applicable. One of the difficulties is that there are a number of explicit discontinuities, such as: (a) Coulomb friction gives a discontinuous law for the forces as a function of velocities, and (b) The contact conditions give forces that are not only discontinuous in position, but also unbounded and give rise to discontinuities in the velocities.
This thesis presents a systematic study on the periodically forced oscillation system with impact. Various existing methods are discussed and compared. In particular, impulsive differential equation, Poincare map and perturbation theory are applied. Two practical cases are included: a first-order system and the Swiss lever escapement mechanism. The latter has significant engineering value as the Swiss level escapement is the key component of mechanical watch movement. The precision dynamic model has very high numerical accuracy in describing/predicting their dynamics. The research helps to optimize the design of a commercial product. The model is validated by means of experiment.
