Holding hands : evaluating quantitative outcomes and parental perceptionsHamlin, Beth Lauren January 2012 (has links)
Background: Behaviour difficulties are one of the commonest problems for which parents seek professional advice. Behaviour difficulties in early childhood are associated with poorer educational and social outcomes in later life (Loeber & Dishion, 1983). The importance of early intervention and preventative work to support behaviour difficulties has been stressed in the literature and is a priority in the government’s strategy for promoting positive outcomes for children. It is now generally accepted that parenting programmes (PPs) are an effective mechanism for supporting children with behaviour difficulties. A review of the literature suggests that while there are numerous evaluations of PPs there is limited evidence of PPs that are successful outside of a clinic setting and even less evidence on particular aspects of PPs and how parents view them. Aims: The main aim of this research was to explore a community based PP (the Holding Hands Group Programme (HHGP)) in terms of both its outcomes and the perceptions of the parents involved. The aim of paper one was to investigate whether families who undergo the HHGP, notice any improvement in child behaviour, parental stress and parental confidence. A second aim was to compare the HHGP to the previously evaluated Holding Hands Individual Programme (HHIP). The aim of paper two was to examine the process elements of the Holding Hands Group Programme (HHGP), seeking new insights and a detailed descriptive portrayal of how parents experience the HHGP. Methods: The study utilised a pragmatic approach to evaluation, with mixed methods and differing methodologies. Paper 1 involved a fixed quasi-experimental design using a pre-test, post-test single group evaluation. Outcome data was gathered from 34 parental responses to a range of psychometric measures completed on each of three occasions. Paper 2 involved semi-structured interviews being carried out with 15 parents prior to, and on completion of, the HHGP. The interviews focused on parent’s experiences of the programme and what they liked/disliked. Results: Paper 1: At the start of the HHGP parents typically reported high levels of intensity of behaviour, behaviour that was a problem and stress levels. They also reported low levels of parental confidence. By the end of the HHGP parents reported significantly increased confidence and significantly reduced stress, intensity of behaviour and behaviour that was problem. These positive results were maintained beyond the end of the programme as indicated at follow-up meetings. The findings indicate that the HHGP was effective for all identified subgroups of the sample. These findings broadly mirror the findings of the evaluation of the HHIP, although results do show some significant differences between the HHIP and the HHGP. Paper 2: The interviews conducted with fifteen parents were analysed using a rigorous approach to thematic analysis to identify emerging themes. Six themes were identified from parental accounts: support, new knowledge, reconstructing, awareness, changes and interactions. Alongside these themes was a practical element about ‘what worked’. Prior to the HHGP parents gave detailed descriptions about the difficulties that they were experiencing with their child, were able to identify what they wanted to achieve through the group and seemed able to predict what might be useful to them. After the sessions parents discussed what they had gained from taking part and were able to give suggestions for what had caused any changes. Extensions and Implications: On methodological grounds it would be desirable to undertake further work with either a control group, or baseline wait list. A further extension would be to use a longer follow up period or to contact the current participants to see how this cohort is coping when they start school. This study relied on self report data, therefore future work could consider the use of videoing interactions. It would also be useful to extend the interview process to include the follow up period. The results of this study imply that PPs can be delivered effectively to groups in non-clinic settings, and this suggests a route to more cost-effective delivery of PPs. However, as the results indicate that the HHGP was not successful for all, it reminds us that practitioners need to be vigilant in attempting to identify those families that are not helped and flexible in trying to assist them in other ways - perhaps via booster sessions or through the use of self-guided written materials.

Evaluating multiple factors that can be used as skill predictors in software proficiencyLarson, Stephen 01 January 2011 (has links)
In this ubiquitous computing society, most students are required to be proficient in computer skills to compete in today’s global job market. These computer skills usually include skills in business productivity applications. Assessing those skills is normally accomplished by hands-on skills exams, which can become onerous and costly. This study explored whether a combination of a computer self-efficacy (CSE) survey, cognitive questions, and skill-based questions could indeed be a valid alternative to a hands-on skills exam. The findings of this study indicate some types of questions may be better predictors of performance on the hands-on skills exam, and some combinations of survey items and questions may be viable alternatives to hands-on skills exams. As a result of this research, schools and companies could adapt these indirect and direct assessments to their situation to perform their own study or assess the skills of their students/employees.

Food safety knowledge and attitudes: investigating the potential benefits of on-site food safety training for folklorama, a temporary food service eventMancini, Roberto January 1900 (has links)
Master of Science / Department: Diagnostic Medicine/Pathobiology / Douglas Powell / Folklorama in Winnipeg, Manitoba, Canada is a 14-day temporary food service event that explores the many different cultural realms of food, food preparation, and entertainment. The ethnic nature and diversity of foods prepared within each pavilion presents a unique problem for food inspectors as each culture prepares food in their own very unique way.
In 2010, the Russian pavilion at Folklorama was implicated in a foodborne outbreak of E.coli
O157 causing 37 illnesses and 18 hospitalizations. Both the Department of Health and Folklorama Board of Directors realized a need for implementation of a food safety delivery
program that would be more effective than a simple 2-hour food safety course delivered via
PowerPoint slides. Until 2011, the 2-hour food safety course delivered to event co-ordinators and food operators for Folklorama pavilions was not mandatory. The course is now mandatory in
2011 for all Folklorama pavilions. Five randomly chosen pavilions were trained on-site, in their
work environment, focusing on critical control points specific to their menu. A control group
(five pavilions) did not receive on-site food safety training. Critical infractions noted on
standardized food inspection reports were assessed. Results of the current study suggest no
statistically significant difference in food inspection scores between the trained group and control group. Results imply that the 2-hour food safety course delivered via slides was sufficient to pass public health inspections.

Development of an Interactive, Hands-on Learning Experience of the Google Maps APIKale, Rushikesh Digambar 14 May 2010 (has links)
The project is to design and implement a Web application for realizing an innovative, hands-on interactive learning experience for the Google Maps API. This learning environment was developed based on a real-world Geographic Information System (GIS), the Gulf of Mexico Coastal Geospatial Information Support System. Significant efforts were invested not only in development of this GIS system, but also in the design and implement that turns the production system into a learning environment. The Web development aspect attracts computer science students, while the opportunity to learn GIS concepts in an interactive way to attract students from the geography department and the opportunity to learn the Google Maps API proves interesting to regular internet users. The Web learning system was given to a focus group whose feedback was collected through a survey. The survey results reveal a favorable response to the interactive, hands-on learning model and the Web implementation.

Spatial, Spectral, and Perceptual Nonlinear Noise Reduction for Hands-free Microphones in a CarFaneuff, Jeffery J 06 August 2002 (has links)
"Speech enhancement in an automobile is a challenging problem because interference can come from engine noise, fans, music, wind, road noise, reverberation, echo, and passengers engaging in other conversations. Hands-free microphones make the situation worse because the strength of the desired speech signal reduces with increased distance between the microphone and talker. Automobile safety is improved when the driver can use a hands-free interface to phones and other devices instead of taking his eyes off the road. The demand for high quality hands-free communication in the automobile requires the introduction of more powerful algorithms. This thesis shows that a unique combination of five algorithms can achieve superior speech enhancement for a hands-free system when compared to beamforming or spectral subtraction alone. Several different designs were analyzed and tested before converging on the configuration that achieved the best results. Beamforming, voice activity detection, spectral subtraction, perceptual nonlinear weighting, and talker isolation via pitch tracking all work together in a complementary iterative manner to create a speech enhancement system capable of significantly enhancing real world speech signals. The following conclusions are supported by the simulation results using data recorded in a car and are in strong agreement with theory. Adaptive beamforming, like the Generalized Side-lobe Canceller (GSC), can be effectively used if the filters only adapt during silent data frames because too much of the desired speech is cancelled otherwise. Spectral subtraction removes stationary noise while perceptual weighting prevents the introduction of offensive audible noise artifacts. Talker isolation via pitch tracking can perform better when used after beamforming and spectral subtraction because of the higher accuracy obtained after initial noise removal. Iterating the algorithm once increases the accuracy of the Voice Activity Detection (VAD), which improves the overall performance of the algorithm. Placing the microphone(s) on the ceiling above the head and slightly forward of the desired talker appears to be the best location in an automobile based on the experiments performed in this thesis. Objective speech quality measures show that the algorithm removes a majority of the stationary noise in a hands-free environment of an automobile with relatively minimal speech distortion."

A Rediscovered Genius, Carl Czerny and his F minor Grand Piano Sonata, Op.178: A Critical Analysis and Performance GuideJanuary 2019 (has links)
abstract: Between the years of 1818 and 1833 the Austrian composer, teacher, and pianist, Carl Czerny (1791–1857) wrote one of his greatest compositions, the f minor Grand Piano Sonata, Op.178 for piano four hands. Overshadowed by composers like Ludwig van Beethoven, Frederic Chopin, Robert Schumann, Johannes Brahms and possibly because of Czerny’s prolific pedagogical output, this work has received little scholarly attention and is rarely performed.
The aim of my paper is first to provide a concise background of the composer for better insight of his ideas and influences and, second to provide a theoretical framework and analysis of the composition to show how this piece is uniquely set in the musical backdrop among early nineteenth century piano music. Further, I will demonstrate performance concepts and ideas of the composition highlighting his instructional mastery. There are two components for this project including a research paper and a lecture recital.
I hope this project could bring more musicians and audiences to Carl Czerny’s serious and concert music as he categorized his music. He had been a great model of true artist, he composes, teaches and perhaps not the greatest promoter of his own music like the contemporaries. However, he devoted most of his life to development of music and the new generation of pianists, which is the most honorable of an individual. / Dissertation/Thesis / Doctoral Dissertation Music 2019

Le langage des mains dans les arts figurés en France (1604-1795) / Language of the hands in the figurative arts of France (1604-1795)Dimova, Temenuzhka 26 September 2017 (has links)
Le langage iconographique des mains est un système conventionnel utilisé par les peintres afin de doter les personnages de leurs oeuvres de fonctions discursives, affectives et symboliques particulières. La lecture des gestes figurés nous a ainsi permis de révéler des nouvelles structures narratives. Les différents signes gestuels sont étudiés ici en fonction de leurs origines, usages, connotations et stylistiques dans l’art français des XVIIe et XVIIIe siècles. Dans l’objectif de comprendre le potentiel sémantique de la main et son implication dans les oeuvres d’art, nous avons sollicité des écrits issus de champs épistémiques multiples. Lors de ce travail, nous avons souligné l’importance de la chirologie, discipline explorant les configurations signifiantes des mains et leurs possibles applications. Les gestes picturaux ne fonctionnent pas uniquement de manière isolée mais sont impliqués dans des schémas d’interaction, raccordés au genre et à la composition de l’oeuvre. L’étude du langage des mains favorise le dialogue entre l’histoire de l’art et d’autres disciplines scientifiques, engagées dans des questions de perception, de représentation et de mémoire. / The iconographic language of the hands is a conventional system used by the painters in order to provide some particular discursive, affective and symbolical functions to their characters. In our work, we show that the analysis of the figurative gestures reveals new narrative structures. The different gestural signs are studied according to their origins, usages, connotations and stylistics in the French art of the 17th and 18th centuries. With the aim of understanding the semantic potential of the hand and its implication in the works of art, we referred to multiple epistemic fields. In this study, we underline the importance of the chirology, discipline exploring the meaningful configurations of the hands and their possible applications. The pictorial gestures are not isolated but involved in interactional schemas, connected to the genre and the composition of the work of art. The study of the language of the hands favours the dialogue between the History of art and other scientific disciplines,engaged in the questions of perception, representation and memory.

An evaluation of hands-on activities in terms of learning environment, achievement, and attitudes in grades 4 and 5Hilton, Elton January 2006 (has links)
A sample of 817 Grade 4-5 mathematics students in the diverse school district of Miami-Dade County Public Schools (MDCPS), Florida, USA was involved in an evaluation of the use of hands-on activities in terms of students' achievement, students' attitudes and students' perceptions of the mathematics classroom environment. Other aims included validating generally-applicable measures of classroom learning environments and students' attitudes to mathematics, and investigating associations between the classroom learning environment and the student outcomes of performance and attitudes. The study was conducted in two phases. Phase 1 had a sample of 442 participants and classroom environment was assessed with scales selected from the My Class Inventory, Questionnaire on Teacher lnteraction and Science Laboratory Environment Inventory. Factor analysis provided a degree of support for the factorial validity and internal consistency reliability (using Cronbach's alpha coefficient) for each of five classroom environment scales. Because of the small number of items per scale (15 items in five scales for the My Class Inventory, 12 items in four scales for the Question on Teacher Interaction and 15 items in five scales for the Science Laboratory Environment Inventory) in Phase I, it was not possible to replicate the a priori factor structure of each instrument scale. Scale reliabilities generally were acceptable. Phase 2, involving a sample of 375 Grades 4 and 5 students in four elementary schools, was necessary because questionnaires in Phase 1 had too few items to enable the researcher to establish satisfactory levels of reliability and validity. / The What Is Happening In this Class? (WIHIC) was modified to four scales and 29 questions for use in Phase 2. Factor analysis supported the structure of the WIHIC and internal consistency reliability was satisfactory for two units of analyses, namely, the individual and the class mean. In Phase 1 of the study, differences between an experimental group (that used manipulatives for 60% of the time) and a control group (that used manipulatives for less than 40% of the time), were described in terms of the effect size (magnitude of the difference in standard deviations) and statistical significance for each learning environment, attitude, and achievement scale. Differences between the pretest and posttest for the set of six dependent variables (Student Cohesiveness, Teacher Support, Task Orientation, Cooperation from the WIHIC and Adoption of Mathematical Attitudes and Enjoyment of Mathematics Lessons for the TOMRA) were analyzed in Phase 2 using a MANOVA for repeated measures. Effect sizes were used to describe the magnitude, as distinct from the statistical significance, of prepost changes. In Phase 2, associations between student attitudes and their perceptions of the learning environment were relatively weak for both pretest and posttest data with either the individual or the class mean as the as the unit of analysis. These results were unexpected and are inconsistent with past research, therefore highlighting the need for further research.

Value Creation in Buyouts : Value-enhancement practices of private equity firms with a hands-on approachBengtsson, Patrik, Nagel, Ron, Nguyen, An January 2008 (has links)
Abstract: Swedish private equity firms have demonstrated a historical success in the buyout industry. However, current trends in the industry such as institutional changes, phenomenon of capital overhang and an influx of new entrants have intensified competition among buyout firms. To maintain the expected high gains, private equity firms must actively create values for their portfolio companies. The purpose of this study is to describe and analyze how private equity firms with a hands-on approach add value to the companies under management. A literature review on value-creation by private equity firms was conducted. The valuecreation methods were classified by the authors under the four themes: governance engineering, financial engineering, operational engineering, and strategic redirections. In order to collect the empirical data, the authors chose an inductive approach, used semi-structured interviews with representatives from five private equity firms. The results show that the studied firms undertake to a large extent similar actions when it comes to corporate governance and financial engineering. With governance engineering, the firms attempt to strengthen the portfolio companies’ governance system through proper due diligence, the appointment of a competent and independent board of directors, an appropriate and deep management incentive program, establishment of a close relationship with management, and periodic management reports. The key to efficient governance is to give the portfolio firms 100% focus on operational and strategic issues in the board meetings. All but one firm use significant debt to lever the buyouts as it is evident that the pressure of debt repayment incentivizes management to better handle scarce capital. Operational engineering and strategic redirection are the two themes in which the firms mainly distinguish themselves. Operational engineering largely concerns running operation more efficiently through a combination of cost-cuttings (divestment of non-profitable product and customer, outsourcing, centralizing purchases) and higher revenue growth (finding new markets, providing more after-sale service, extending product range). Strategic redirection incorporates the focus on core competences, making strategic decisions about investments, divestments, and add-on acquisitions. There have been differences in actions taken by the studied firms. Factors that could affect the behavior of private equity firms are the type of companies acquired, the firm size, their perception of risk and reward regarding a particular action, as well as years of experiences in the industry. There is no common timeframe for actions taken by the studied firms. Nevertheless, all firms emphasize the importance of implementing fundamental changes in the early years of the investments.
