<b>Predicting The Risks of Recurrent Stroke and Post-Infection Seizure in Residents of Skilled Nursing Facilities - A Machine Learning Approach</b>Madeleine Gwynn Stanik (18422118) 22 April 2024 (has links)
<p dir="ltr">Recurrent stroke, infection, and seizure are some of the most common complications in stroke survivors. Recurrent stroke leads to death in 38.6% of survivors, and infections are the most common risk factor for seizures, with stroke survivors that experience an infection being at greater risk of experiencing a seizure. Two predictive models were generated, recurrent stroke and post-infection seizure, to determine stroke survivors at greatest risk to help providers focus on prevention in higher risk residents.</p><p dir="ltr">Predictive models were generated from a retrospective study of the Long-Term Care Minimum Data Set (MDS) 3.0 (2014-2018, n=262,301). Techniques included three data balancing methods (SMOTE for up sampling, ENN for down sampling, and SMOTEENN for up and down sampling) and three feature selection methods (LASSO, RFE, and PCA). The resulting datasets were then trained on four machine learning models (Logistic Regression, Random Forest, XGBoost, and Neural Network). Model performance was evaluated with AUC and accuracy, and interpretation used SHapley Addictive exPlanations.</p><p dir="ltr">Using data balancing methods improved the prediction performances of the machine learning models, but feature selection did not remove any features or affect performance. With all models having a high accuracy (78.6% to 99.9%), interpretation on all four models yielded the most holistic view. For recurrent stroke, SHAP values indicated that treatment combinations of occupational therapy, physical therapy, antidepressants, non-medical intervention for pain, therapeutic diet, anticoagulants, and diuretics contributed more to reducing recurrent stroke risk in the model when compared to individual treatments. For post-infection seizure, SHAP values indicated that therapy (speech, physical, occupational, and respiratory), independence (activities of daily living for walking, mobility, eating, dressing, and toilet use), and mood (severity score, anti-anxiety medications, antidepressants, and antipsychotics) features contributed the most. Meaning, stroke survivors who received fewer therapy hours, were less independent, and had a worse overall mood were at a greater risk of having a post-infection seizure.</p><p dir="ltr">The development of a tool to predict recurrent stroke and post-infection seizure in stroke survivors can be interpreted by providers to guide treatment and rehabilitation to prevent complications long-term. This promotes individualized plans that can increase the quality of resident care.</p>

Encouragement, Enticement, and/or Deterrent: A Case Study Exploring Female Experience in a Vocational Education (VET) Initiative in Northern EnglandParris, Sandra A. 05 November 2013 (has links)
This case study examined how a group of young girls at a secondary school in northern England made sense of their participation in a gender specific vocational education initiative designed to encourage female interest in skilled trade education and professions. The investigation consists of a qualitative case study that included ‘practical’ and historical components. On the practical side, the study looked at a gender specific initiative (girls only) aimed at Year 9 students (12-14 years old) at Garden Road Community and Technology School. The one-day sessions were held at local area colleges or vocational education and training (VET) training facilities and covered skilled trade fields that are traditionally male-dominated (e.g. automotive, construction and engineering). My methodology for the study consisted of two data sources, interviews and a review of public VET policy-related documents. The data was gathered using two methods, with individual and group interviews as the primary one, and public VET policy-related document analysis as the secondary one. In total, 13 current, 2 former and an additional 2 formerly registered (now graduates who decided to pursue non-traditional vocational education and professions) students at the school were interviewed. Beside former and current students, interviews were conducted with 2 instructors and 1 senior administrator at the school. The selection of government policy-related documents covered 2002 to 2011.
The study is framed by a feminist informed genealogy that invokes Foucault’s (1990) notion of ‘biopower’ and Pillow’s (2003) notion of the ‘gendered body.’ Meanwhile, Ted Aoki’s (2003) concepts of curriculum-as-plan and curricula-as-lived are used to analyze and discuss the review of UK government policy-related documents and participant narratives. The theme-based presentation of student narratives centred on the girls’ understanding and experience of: the session process and content; gender; non-traditional VET as educational and occupational options; and the impact of the sessions on their educational and professional choices.
The student narratives suggest several things that relate to their understanding of gender and non-traditional VET. First, the sessions proved to be both interesting and informative and students expressed an interest in taking part in more (and) varied gender-specific sessions. Second, traditional constructions of gender and gendered behavior are commonly used in job-related discourse as evidenced by the use of the terms ‘boys jobs’ and ‘girls jobs’ among the students. In addition, students had limited opportunities for exposure to non-traditional VET education and professions; and what knowledge they do have is generally dependent upon family knowledge and experience in the area. From a document review standpoint, the findings show that government commitment in terms of interest and financial backing for VET has been inconsistent. Resultantly, schools are left to identify and maintain a range of community-based partnerships that may not always see gender segregation in VET as a major concern.
The significance of this study rests in the presentation of the girls’ ‘lived curriculum’ and ‘gendered’ experiences as points that can offer insight into what transpires within vocational education initiatives and settings. Furthermore, from a feminist perspective the research also highlights the continued need to work with schools on how gender is presented, discussed and understood among students. Failure to consider the gendered nature of discourse about education and professional options that takes place within school and class settings limits students’ perspectives about what is available and possible.

Registered nurse practice and information flow in long-term care nursing homesWei, Quan 02 May 2016 (has links)
Little is known regarding registered nurse (RN) information management practice in long-term care (LTC) settings. This study identifies LTC RNs’ information management practice and needs, which are important for designing and implementing health information technology (HIT) in LTC settings.
Methods: This descriptive qualitative study combines direct observations and semi-structured interviews, conducted at Alberta’s LTC facilities between May 2014 and August 2015. The constant comparative method of joint coding was used for data analysis.
Results: Nine RNs from six nursing homes participated in the study. Based on the RNs’ existing information management system requirements, a graphic information flow model was constructed.
Conclusion: This baseline study identified key components of LTC RNs’ information management system. The information flow model may assist HIT developers with future design and development of HIT solutions for LTCs, serve as a communication tool between RNs and developers to refine requirements and support further LTC HIT research. / Graduate

Exploring what companies are doing to manage the shortage of technical skills in the South African manufacturing sector of fast moving consumer goodsMoodley, Thigenthren 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2014. / The government of South Africa aspires to achieve a six percent economic growth per annum. The
scarcity of qualified and experienced people that are crucial in contributing to economic growth and
creating job opportunities, poses a problem for the country. The current demand for skills that are
out of reach for many workers and the prevailing unemployment that is caused by the mismatch
between what an organisation seeks and what a potential candidate can provide, have been
highlighted as a critical cause for the scarcity of skills. The aim of this research assignment was to
examine the current crisis of the skills shortage in the South African economy, with the focus on
the manufacturing sector within the FMCG industry.
Semi-structured and open-ended interviews with human resource, training and development, as
well as technical managers in manufacturing organisations in Cape Town, South Africa were
conducted. Data was obtained from a sample of six managers.
According to all respondents interviewed, it takes approximately two to six months to replace an
employee who has the appropriate technical skills.
All the respondents are concerned with the situation of the technical skills shortage in the country.
Consequently, these respondents’ companies engage in a talent war in order to recruit the best
talent. It is therefore obvious that the market dynamics of supply and demand are out of equilibrium
with regard to technically skilled employees in the manufacturing segment of the South African
FMCG industry.
The interviews that were conducted identified some companies that train new employees in
technical skills. However, the majority of the companies are not doing much to improve the
situation. In addition, the companies in this sector also compete with the other industries in the
South African and the global economy regarding technical skills.

Saudization and skill formation for employment in the private sectorAl-Shammari, Serhan Abdullah January 2009 (has links)
The development in the Kingdom of Saudi Arabia has been associated with its growing petroleum industry since late 1930s. This development has created a sudden wealth in the country that shaped its labour market as well as its skill formation systems in the years after. It has also, thanks to the government involvement, developed the country’s world class economy and its evolving private sector. However, this involvement has also created a duel labour market in which Saudis expect employment in the government while expatriates are continuously employed in private organizations. Employment in the government was always available to Saudis regardless of their qualifications which are dominated by theoretical literary majors over scientific and technical degrees. In the early days of the country’s development this did not produce major concerns to the government nor to Saudis. However, the country is producing one of the highest growth rates in the world with the majority of its citizens are under the age of 19. Government employment is always limited as the majority of employment opportunities are available in the country’s private sector. Since the late 1980s, this has generated high rates of unemployment among Saudis as government employment reached its peak and as the private sector continues in recruiting millions of cheap expatriates to increase its profits and competitiveness. This is creating an unbalanced labour market structure as well as economic, political and social problems. A number of government initiatives have been introduced to rectify such dilemma. One of which is Saudization to replace the country’s 4.7 million of expatriates recruited mainly (95%) in the private sector with as many qualified Saudis as possible. However, such efforts has not yet produced fruitful results as the private sector is still recruiting expatriates and as skill formation systems are still producing Saudis with incompatible skills, knowledge and attitudes with the private labour market needs. This research assumes that ineffective Saudization in the private sector is not the core problem of the employment process in Saudi Arabia. In fact it is the outcome of the government’s heavy and unnecessary involvement and control over skill formation systems in the Kingdom especially over the General Organization for Technical Education and Vocational Training (GOTEVT) which is the main skill formation provider for the private labour market This involvement imposes the government’s rigid bureaucracy and limited funding on a very dynamic, flexible and self-sufficient economy like the private market in Saudi Arabia that is operating in a very competitive and changeable environment. Investigation of such argument against empirical findings from interviews with a number of government, quasigovernment and private sector managers supports such conclusion. It even illustrates that government involvement and bureaucratization is hindering the implementation of Saudization strategy itself in private organizations. Recommendations are made about changing the role of GOTEVT to create industry-led training organizations to serve and link the outcomes of this skill formation organization to the employment needs of the labour market and to the needs of the economy in general.

Impact de l'ouverture commerciale sur le marché du travail des pays en voie de développement : le cas de la Tunisie. / Impact of trade liberalization on labour market in developing countries : the case of TunisiaMrabet, Zouhair 12 July 2010 (has links)
Notre travail de recherche dans le cadre de cette thèse a porté sur les effets de la libéralisation commerciale sur le marché du travail des pays en voie de développement, avec une application spécifique à l'économie tunisienne. Nous avons structuré notre analyse sur le sujet autour de deux axes. Dans un premier temps, nous avons étudié l'impact des échanges commerciaux sur le marché du travail, et dans un deuxième temps nous avons étudié le rôle du changement technologique induit par l'ouverture commerciale. Notre recherche a présenté et discuté la littérature théorique et empirique et les faits stylisés sur le sujet. Dans notre cas d'étude sur la Tunisie nous avons estimé les équations de l'emploi total, de l'emploi du travail qualifié, de l'emploi du travail non qualifié, de l'emploi relatif entre le travail qualifié et non qualifié et du salaire réel. Les variables clés dans ces équations sont celles qui mesurent les échanges commerciaux et celles qui mesurent le changeme nt technologique importé.Les principaux résultats peuvent être résumés de la manière suivante :- L'ouverture commerciale a joué un rôle important dans le changement de la structure de l'emploi sur le marché du travail tunisien.- Le marché du travail tunisien enregistre les mêmes évolutions que celles observées dans plusieurs pays en voie de développement (tels que les pays d'Amérique Latine et d'Asie de l'Est).- Ces évolutions se manifestent par une augmentation de l'emploi relatif du travail qualifié par rapport au travail non qualifié.- Les statistiques descriptives montrent que les inégalités de salaire ont augmenté en Tunisie.- Le changement technologique biaisé vers les travailleurs qualifiés a été un facteur déterminant dans cette évolution en Tunisie. La technologie incorporée dans les machines et les équipements importés augmente l'emploi relatif des travailleurs qualifiés par rapport aux travailleurs non qualifiés. / We analyse the effects of trade liberalization on the labor market of developing countries, with specific application to the Tunisian economy. We have structured our analysis around two axes. Initially, we studied the impact of trade on the labor market, and in a second step we studied the role of technological change induced by trade openness. Our research presented and discussed the theoretical and empirical literature and stylized facts on the subject. In our study of Tunisian case we estimated equations of total employment, employment of skilled labor, employment of unskilled labor, relative employment between skilled and unskilled labor and real wages. The key variables in these equations are those which measure the trade and those that measure the imported technology.The main results can be summarized as follows:- Trade openness has played an important role in changing the structure of employment in the Tunisian labor market.- The evolution of Tunisian labor market has the same trends as those observed in several developing countries (such as the countries of Latin America and East Asia).- These changes are manifested by an increase in employment of skilled labor relative to unskilled labor.- The descriptive statistics show that wage inequality increased in Tunisia.- Technological change biased towards skilled workers has been a factor in this evolution in Tunisia. The technology embodied in imported machinery and equipment raises relative employment of skilled workers relative to unskilled workers.

Lorsque l'imaginaire migratoire rencontre les réalités de la migration : parcours de migrants volontaires et qualifiés de l'Afrique de l'Ouest au QuébecMichaud, Valérie 08 1900 (has links)
Différentes réalités et contextes actuels mondiaux font en sorte que de plus en plus de gens envisagent la migration comme projet de vie. La présente recherche s’intéresse à l’imaginaire migratoire comme facteur de mobilité, mais également comme facteur de modulation des réactions et du regard qu’entretiendra le migrant en rapport avec son vécu migratoire. Ainsi, la réflexion s’amorce en Afrique de l’Ouest, tandis que de jeunes Africains instruits et qualifiés élaborent un projet de migration volontaire vers le Canada, plus précisément dans la région du Québec. C’est investi de leur désir de l’Ailleurs, des représentations de l’Occident, de leur besoin de se réaliser et de l’impossibilité qu’ils rencontrent à accéder à la vie professionnelle souhaitée en Afrique qu’ils migrent vers le Canada. Quoiqu’ils soient dotés d’une détermination et d’un optimisme considérable, la rencontre entre l’imaginé et le quotidien de la vie au Québec comme immigrant et comme émigrant n’est pas toujours facile. Elle viendra révéler la profondeur du rêve, des mythes et des ambitions; les failles intérieures individuelles, les valeurs et les ambivalences de chacun, mais surtout la capacité qu’aura l’individu à revoir son imaginaire, à effectuer la réappropriation de son expérience migratoire et à élaborer de nouveaux projets. L’écart vécu par le sujet entre l’imaginé et le rencontré nous questionnera sur ce que véhiculent les messages et les images en circulation sur le Canada et l’Occident. Aussi, il témoignera de la prédominance de la préparation factuelle et psychologique de l’individu pour anticiper et mieux accueillir les réalités du parcours migratoire. / Different realities and contexts in today’s world are causing more and more people to consider migration as a life plan. This study is interested in their imagined migration as a mobility factor, but also as a modulation factor in the reactions and views of migrants in relation to their migration experience. Thus, this study begins in West Africa, where young educated and qualified Africans eagerly plan their migration to Canada, and Quebec in particular. Their migration to Canada is fuelled by a longing to go abroad, representations of the West, their quest for self-fulfillment and the impossibility of achieving their desired career plans in Africa. Although they are filled with a great deal of determination and optimism, the clash between what they imagined and the reality of daily life in Quebec as immigrants and emigrants is not always easy. This study will not only reveal the depth of their dreams, myths and ambitions, but their individual flaws, values and uncertainties, and above all, their ability to re-examine their imagined migration, reclaim the migration experience and make new plans. The difference between the imagined experience and the actual experience will lead us to question what conveys the messages and images that circulate about Canada and the West. Moreover, it will demonstrate the predominance of the factual and psychological preparation undertaken by individuals to anticipate and more readily accept the realities of the migration experience.

New methods for the multi-skills project scheduling problem / Nouvelles méthodes pour le problème de gestion de projet multi-compétenceMontoya casas, Carlos Eduardo 13 December 2012 (has links)
Dans cette Thèse, nous avons introduit plusieurs procédures pour résoudre le problème d’ordonnancement du projet multi-compétences (MSPSP). L’objectif est de trouver un ordonnancement qui minimise le temps de terminaison (makespan) d’un projet, composé d’un ensemble d’activités. Les relations de précédences et les contraintes de ressource seront considérées. Dans ce problème, les ressources sont des membres du personnel qui maîtrisent plusieurs compétences. Ainsi, un certain nombre de travailleurs doit être affecté pour utiliser chaque compétence requise par une activité. Par ailleurs, nous accorderons une importance particulière aux méthodes exactes pour résoudre le MSPSP, puisqu’il y a encore un certain nombre d’instances pour lesquelles l’optimalité doit encore être prouvée. Néanmoins,pour traiter des instances plus importantes, nous implémentons une approche heuristique. / In this Phd Thesis we introduce several procedures to solve the Multi-Skill Project Scheduling Problem (MSPSP). The aim is to find a schedule that minimizes the completion time (makespan) of a project, composed of a set of activities. Precedence relations and resource constraints are considered. In this problem, resources are staff members that master several skills. Thus, a given number of workers must be assigned to perform each skill required by an activity. Furthermore, we give a particula rimportance to exact methods for solving the Multi-Skill Project Scheduling Problem (MSPSP), since there are still several instances for which optimality is still to be proven. Nevertheless, with the purpose of solving big sized instances we also developed and implemented a heuristic approach.

Impact of a training programme on food preparation knowledge and skills of food service workers at Sharpeville care of the agedSinthumule, Lufune 05 1900 (has links)
M. Tech. (Department of Hospitality, Faculty of Human Sciences) Vaal University of Technology / Introduction: The education, training and development (ETD) industry has
developed fast over the past few years in our country. One need only read the
national weekend papers and see all the ETD vacancies advertised to realise
that ETD issues are being given increased coverage in this country. The reason
for this increased focus on ETD is the need for skilled workers in organisations.
Reports on our competitiveness in the world have consistently identified the lack
of people development as a major stumbling block for the South African economy
in competing in the global market. Objectives: The main objective of this study
was to measure the impact of a training programme for the food service workers
providing meals to 300 elderly people attending the Sharpeville Care of the Aged
centre, in terms of a skills development programme, in order to contribute to
increased productivity and provide nutritious meals to the elderly.
Methods: A baseline survey was undertaken to determine the nutritional status,
food consumption patterns and nutrient intake in a random sample of 300 elderly
people attending the care centre five days a week. Socio-demographic and
health questionnaires, as well as 24-hour recall questionnaires were completed
with the assistance of trained fieldworkers. Anthropometric measurements
included weight, height, and Mid-Upper Arm Circumference. Furthermore, the
existing menus served to the elderly were theoretically analysed using
FoodFinder® version 3 program to determine the energy, carbohydrate, protein
and fat content. A developed and tested questionnaire was used to gather
information from ten volunteer food service workers at the care centre to
determine the training needs. The results of the baseline survey, the menu
analysis and training needs assessment were used to develop a training
programme that was implemented for a period of ten weeks. Learning was
measured after the training programme by administering the same knowledge
questionnaire, as well as by a portfolio of evidence and practical assessment.
Data analyses: Data for the baseline survey was captured on an Excel
spreadsheet. Data analysis was done using the Statistical package for Social Sciences (SPSS) for Windows version 10.0 program for all variables except
dietary intake data. Dietary intake and food consumption data were analysed by
a registered dietician using the FoodFinder® version 3 program, developed by
the Medical Research Council (MRC). Daily nutrient intakes were reported as
means and standard deviations and compared to RDAs. Paired t tests were done
to determine correlations between knowledge of the food service workers before
and after the implementation of the training programme.
Results: The results indicated that the majority of the elderly had an income of
between R500 and R1 000 per month and most of them reported an occasional
lack of funds to meet basic household needs, confirming the presence of food
insecurity. Daily dietary intakes (mean ±Standard Deviation [SD] were 5 041,2 ±
2 299,6 kilojoules (kJ) energy, 50,4 ± 28,2 gram (g) protein, 38,9 ± 28,2 g fat and
149,0 ± 76,6 g carbohydrates. The majority (29.5%) were overweight (body mass
index [BMI] ~25) or obese (BMI ~30) whilst 33.5% had a mid-upper arm
circumference (MUAC) of ~21.7 centimetres (em). Mean intakes of micronutrients
were low in comparison with the reference standards. The volunteer food service
workers were literate as the majority had higher than grade 10-12 training and
80% had previously received on-the-job training. The training programme was
successfully implemented and the knowledge of the voluntary food service
workers improved after the training programme was implemented. However,
because of the small sample size no significance could be determined.
Conclusions: The findings of this study confirmed that poverty, malnutrition,
both under- and over-nutrition, as well as household food insecurity and poor
health were the major problems observed in this elderly community. These
findings correspond to other studies, however limited, conducted amongst the
elderly in South Africa. The results indicated that, although the food service
workers were literate and had received prior training, they still had a poor
knowledge of appropriate food preparation method and practices, as well as
nutrition, especially related to the elderly. On completion of the training
programme, the knowledge of the food service workers improved. This study
emphasises the importance of continued on-the-job training
Recommendations: The recommendations of further research include: 1) A
more detailed study to evaluate the influence of the training programme not only
on knowledge and skills, but also on behaviour and attitude. 2) Periodically
measuring such influence over a year to measure knowledge retention. 3)
Implementation of a NEP for the elderly and its impact on nutrition knowledge
and dietary intake behaviour tested. / National Research Foundation (NRF
