A competitive analysis of the South African mining industry

Linnell, Carey January 2014 (has links)
The aim of this research was to analyse the competitiveness of the South African mining industry in order to assess the viability of mineral beneficiation. This study also aimed to establish what was required in the mining industry in order to provide an environment which enables competitiveness going forward. The Diamond Model of Industry Competitiveness developed by Michael Porter was utilised in analysing the mining industry's competitiveness. In the process of the analysis, the model was interrogated for validity in a developing and dynamic country via inference of the analysis of the South African mining industry. Based on the results of this research, a new model, built on the findings outlined by the Diamond Model, was developed. The research found that the mining industry is not competitive at present and will not be able to provide an environment conducive to beneficiation in South Africa. Investigation further revealed that, as a result of the importance placed on the elements of the model, the Diamond Model is viable in a developing and dynamic environment. The results further provided sufficient feedback regarding how to utilise the elements from the Diamond Model in redesigning the competitive analysis in a forward-looking manner. / Dissertation (MBA)--University of Pretoria, 2014. / zkgibs2015 / Gordon Institute of Business Science (GIBS) / Unrestricted

The changes in the Brazilian and Honduran energy matrix in order to make them more efficient and seeking to contribute to environmental and legal development are the theme of interest in this research. The present work had as general objective to analyze the qualitative and legal development of the energy matrix of Brazil and Honduras and as specific objectives to study the characteristics of the energy matrix and its dependencies of nonrenewable energy in the period from 2000 to 2016 for Brazil and 2000 to 2015 for Honduras and to evaluate the effect of the legal strategies in the change of the energy matrix of both countries through a comparative analysis in the energy legislation of Brazil and Honduras. The methodology used was qualitative by means of a survey, the experimental period was from 11/15/2016 to 03/30/2018 where information and legal norms regarding the objective of this work were sought. Scientific articles were consulted on specialized websites, statistical data on energy consumption were obtained from international organizations. Government official websites consulted the energy legislation of Brazil and Honduras and using as a transversal criterion the updating and validity of the same. As results it was found that both countries are dependent on non-renewable energy to cover energy demand but are on the right path in diversifying their energy matrix, it was also possible to verify that there is a convergence between some energy laws of Brazil and Honduras, as well as other laws that can help in the energy efficiency of the countries improving the socioeconomic development ... / Mestre

The effect of mentoring on the development of leaders : a qualitative study

Swanepoel, Olga Minette 19 April 2013 (has links)
Organisations depend on strong and competent leaders for their sustainability, profitability and competitiveness. Therefore organisations have an extremely strong focus on development, and especially on leader development. Mentoring has been recognised as a developmental tool (Truter, 2008, p.61) and is therefore employed by many organisations to foster such development. The primary aim of this study is to determine whether and to what effect, mentoring can be used to foster leader development in a business context. The research is of a qualitative, phenomenological nature and enquires into the perceptions, personal experiences and knowledge of people who have been exposed to mentoring and leader development, in order to understand how mentoring has played a role in the development of their leadership. In-depth interviews were conducted with a sample of six participants in order to collect the required data; and South African and international literature was consulted in order to interpret the interview data accurately in terms of the primary aim of the study. The study revealed the following results amongst others: <ul> <li> There is a connection between mentoring and leader development and mentoring can be used to develop leaders.</li> <li> Leader development is not possible in the absence of mentoring.</li> <li> Mentoring can contribute to leader development by focussing on a person’s development and teaching that person to become a good or a better leader.</li> <li> Mentoring has the ability to positively impact or benefit leader development.</li> <li> Mentoring has the ability to develop a person’s leadership capability and competence (i.e. his/her ability to be a leader).</li> <li> Mentoring can be used as a tool to develop effective leaders.</li> </ul> / Dissertation (MCom)--University of Pretoria, 2012. / Human Resource Management / unrestricted

Kvinnor med endometrios upplevelser och erfarenheter av fysioterapeutisk behandling. / Women with endometriosis experiences of physiotherapeutic treatment

Björklund, Sanna, Håkansson, Evelina January 2020 (has links)
Bakgrund: Endometrios är en sjukdom som drabbar var tionde kvinna i fertil ålder. Fysioterapi rekommenderas som alternativ behandling eftersom det kan ha en smärtlindrande effekt och höja kvinnornas livskvalité. I litteraturen framkommer inte hur kvinnor med endometrios upplever den fysioterapeutiska behandlingen som helhet. Det finns därför behov av att undersöka hur den fysioterapeutiska behandlingen upplevs av kvinnor med endometrios. Syfte: Utforska kvinnors erfarenheter och upplevelser av endometrios och fysioterapeutisk behandling vid endometrios. Metod: Studien var av kvalitativ design. Semistrukturerade intervjuer genomfördes med fem kvinnor i åldrarna 24–40 år som diagnostiserats med endometrios. Deltagarna rekryterades via en Facebookgrupp och ett Instagramkonto för kvinnor med endometrios. Bekvämlighetsurval tillämpades. Databearbetning av materialet gjordes genom kvalitativ innehållsanalys. Resultat: I analysprocessen formulerades fyra huvudkategorier: Att leva med endometrios, Betydelse av fysioterapeutens förkunskap, Att skapa en trygg miljö med patienten och Individuella upplevelsen av de fysioterapeutiska behandlingarna. Kategorierna lyfter upplevelser och erfarenheter av sjukdomens påverkan i vardagen, fysioterapeutens kunskap och bemötande samt effekten av behandlingsmetoderna. Slutsats: Endometrios beskrevs ständigt påverka informanternas vardag där fysioterapin bidragit till lindring av symtom genom att de fått ny kunskap om smärtan samt individuellt anpassade behandlingar. Det ansågs värdefullt för informanterna att vara delaktiga i val av behandling. Att bli hörd och bekräftad upplevdes som viktigt i mötet med fysioterapeuten. Det framkom olika upplevelser av effekten av TENS, akupunktur, fysisk aktivitet och behandling av bäckenbotten. För att tydliggöra vad som gör behandlingen effektiv behövs fler studier. / Background: Endometriosis is a disease that affects every tenth woman of reproductive age. Physiotherapy is recommended as part of a treatment because it can have a pain-relieving effect and increase quality of life. The literature does not present how women with endometriosis experience the physiotherapeutic treatment. Therefore, there is a need to investigate how physiotherapeutic treatment is experienced by women with endometriosis. Objectives: Examine women's experiences of endometriosis and physiotherapeutic treatment in endometriosis.  Method: The study was of qualitative design. Five semi-structured interviews were conducted with women aged 24–40 diagnosed with endometriosis. They were recruited through a Facebook group and an Instagram account. Convenience sampling was applied. Data processing was done with qualitative content analysis. Results: Four main categories were formulated: Living with endometriosis, Importance of physiotherapist's knowledge, Creating a safe environment with the patient and Individual experience of the physiotherapeutic treatments. The categories highlight experiences of the impact of the disease, the physiotherapist's knowledge and the effect of treatment methods. Conclusion: Endometriosis was described as constantly influencing the everyday lives of informants where physiotherapy has contributed to relief of symptoms by obtaining new knowledge and by individually tailored treatments. It was considered valuable for informants to be involved in the choice of treatment. Being heard and validated was perceived as important. Various experiences of the effect of TENS, acupuncture, physical activity and treatment of the pelvic floor emerged. To clarify what makes the treatment effective, more studies are needed.

Exploring Faculty and Students' Attitudes About Consensual Sexual Relationships and Sexual Harassment on College Campuses

Gimlin, April, Crittenden, Courtney A., Bennett, April, Garland, Tammy S. 12 April 2019 (has links)
Over the last several years, there has been an increased awareness regarding consensual sexual relationships (CSRs) between professors and students. Specifically, there has been a growing movement for academic institutions to develop policies addressing, discouraging, and/or prohibiting these relationships due to the potential for sexual harassment cases. Even though the appropriateness of such relationships has been widely debated among the university community, a limited amount of empirical work has examined this issue with the majority focusing on attitudinal studies. The current exploratory study consists of a content analysis of 278 faculty and student responses to the question, “If there is a difference between consensual sexual relationships and sexual harassment, what is it?” Responses indicate that there are several overlapping themes for both faculty and students in how they view these differences, with a large number of responses specifically indicating themes such as “CSR is consensual” while “sexual harassment is one sided.” There are also some unique perspectives given by faculty regarding the complexities and acceptability of CSRs, who are generally more specific and nuanced in their answers. Considering the complexities of this issue, it is the recommendation of the current study that much more research fully exploring the attitudes of faculty and students is needed to develop a well-rounded and comprehensive policy.

Exploring the Process and Challenges of Programming with Regular Expressions

Michael, Louis Guy IV 27 June 2019 (has links)
Regular expressions (regexes) are a powerful mechanism for solving string-matching problems and are supported by all modern programming languages. While regular expressions are highly expressive, they are also often perceived to be highly complex and hard to read. While existing studies have focused on improving the readability of regular expressions, little is known about any other difficulties that developers face when programming with regular expressions. In this paper, we aim to provide a deeper understanding of the process of programming regular expressions by studying: (1) how developers make decisions through the process, (2) what difficulties they face, and (3) how aware they are about serious risks involved in programming regexes. We surveyed 158 professional developers from a diversity of backgrounds, and we conducted a series of interviews to learn more details about the difficulties and solutions that participants face in this process. This mixed methods approach revealed that some of the difficulties of regexes come in the shape of: inability to effectively search for them; fully validate them; and document them. Developers also reported cascading impacts of poor readability, lack of universal portability, and struggling with overall problem comprehension. The majority of our studied developers were unaware of critical security risks that can occur when using regexes, and those that were aware of potential problems felt that they lacked the ability to identify problematic regexes. Our findings provide multiple implications for future work, including development of semantic regex search engines for regex reuse, and improved input generators for regex validation. / Master of Science / Regular expressions (regexes) are a method to search for a set of matching text. They are easily understood as a way to flexibly search beyond exact matching and are frequently seen in the capacity of the find functionality of ctrl-f. Regexes are also very common in source code for a range of tasks including form validation, where a program needs to confirm that a user provided information that conformed to a specific structure, such as an email address. Despite being a widely supported programming feature, little is known about how developers go about creating regexes or what they struggle with when doing so. To gain a better understanding of how regexes are created and reused, we surveyed 158 professional developers from a diversity of backgrounds and experience levels about their processes and perceptions about regexes. As a followup to the survey we conducted a series of interviews focusing on the challenges faced by developers when tackling problems for which they felt that a regex was worth using. Through the combination of these studies, we developed a detailed understanding of how professional developers create regexes as well as many of the struggles that they face when doing so. These challenges come in the form of the inability to effectively search for, fully validate, and document regexes, as well as the cascading impacts of poor readability, lack of universal portability, and overall problem comprehension.

Developing Recommendations to Guide Future Evidence Generation, Evidence Synthesis, and Knowledge Translation for Rare Diseases

Tingley, Kylie 22 April 2021 (has links)
Introduction: The scarcity of rigorous evidence regarding rare disease therapies contributes to uncertainty for stakeholders who make decisions about the use, prescription, or funding of such therapies. My dissertation objective was to integrate stakeholder perspectives and evidence related to how rare disease therapies are evaluated to better understand drivers of uncertainty in decision making and develop an evaluation framework for future evidence generation, synthesis, and decision support. Methods: To better understand the perceived challenges in generating robust treatment effectiveness evidence, and describe various methods for mitigating these challenges, I used a meta-narrative literature review. I also conducted focus group interviews with key rare disease stakeholders (patients/caregivers, physicians, and policy advisors) to elicit different perspectives on how evidence is generated, evaluated, and synthesized in the context of health care decision making, both at a personal and population level. Finally, I integrated the focus group findings with a targeted literature review to identify characteristics of rare diseases and their candidate therapies that may warrant special consideration in health technology assessment (HTA) and health care decision making. Findings: My dissertation data revealed three fundamental challenges in generating robust treatment effectiveness evidence for rare diseases: limitations in recruiting a sufficient sample; inability to account for clinical heterogeneity; and reliance on outcomes with unclear clinical relevance. Several methodological solutions have been proposed to overcome these challenges. In addition, study participants described different perspectives on how they choose to participate in and use research in their roles as health care users, care providers, and policy advisors. Notably, conventional wisdom that patients/caregivers participate in clinical research studies because of therapeutic misconception was not supported. Finally, focus group and literature review findings identified information that potentially warrants special consideration in future HTA specific to rare diseases, including characteristics of the disease, understanding of causal hypotheses relevant to the therapy, and complexities of cost-effectiveness given the high price of many rare disease therapies. Discussion: Together, the findings from this dissertation support an evaluation framework with eight key principles that aim to mitigate important aspects of uncertainty from various stakeholder perspectives and promote evidence-informed decision making about rare disease therapies.

Official Language Minority Communities in Ontario: Understanding the Lived Experiences of Francophone Patients and Their Nursing Care Providers

Muray, Mwali 28 February 2022 (has links)
Although Canada is a bilingual country, official language minority community patients struggle to access quality care in their language. This reality has been of concern for Francophone minority communities in Ontario, but has seldom been examined in a nursing context. This research sought to examine the lived experiences of registered nurses and nursing students providing care to French-speaking patients in Ontario, as well as the realities of Francophone patients seeking French language health care services in Ontario. The conceptual frameworks guiding the study were the “Four Levels of Change for Improving Quality” model and the “Four-Level Model of the Health Care System.” Using qualitative phenomenological inquiry, as influenced by Martin Heidegger and Max van Manen, 31 semi-structured interviews were conducted with three subsets (n=10 Francophone patients; n=10 nursing students; n=11 registered nurses) throughout Ontario who had experience with the phenomenon being investigated. Data collection took place over a year (2018-2019) and was analysed thematically. Significant findings were identified across the three groups. Participants revealed the patchwork of individual actions taking place to remedy the existing gaps regarding care for Francophone minority populations. This included navigating a health care system where good enough care was the unfortunate standard for Francophone patients, and discussing how Francophone patients and nursing care providers implement strategies individually to manage the lack of resources for Francophone patient populations in Ontario. This thesis asserts that official language minority communities and their nursing care providers remain faced with difficulties providing and receiving care in Ontario. While numerous structures and resources exist to remediate the problems, these interventions and resources are not always implemented systemically, leading to a disproportionate burden on individuals, significant risks for safety for patient populations, and ethical dilemmas for nursing care providers. Recommendations are provided to bridge the gaps and ensure considerations of the needs of linguistic minorities throughout the health care system.

"A Walk Through the Jungle at Twilight": How Parents Experience a Transition to Adolescence

Spring, Elizabeth L. 04 November 1998 (has links)
This study examined how parents experienced their first child's transition to adolescence. A multiple-case qualitative research design was chosen to examine parents' experiences. Family systems theory and family stress and coping theory provided a theoretical starting point. Participants were recruited who had adolescents between ages 13 and 16 and saw their family as normally stressed, indicated in part by an absence of court involvement, substance abuse issues, school failure, and participation in therapy. Ten families were selected: parents from eight of these families participated in focus groups, and five sets of parents were interviewed in their homes. The grounded theory approach to qualitative inquiry developed by Glaser and Strauss guided data collection and analysis. This study identified a complex array of intrapersonal, interpersonal, and contextual factors involved in parents' experience of this transition. A theoretical model was developed to illustrate how specific components of parents' experiences might be interrelated. The process seemed to be initiated when the parents noticed a physical, social/emotional, or relational change in their teenager. Parents responded to the perceived change through their affect, cognition, and behavior. They interpreted what was happening by processes of evaluation, reorientation, and frame. These three components-perception, response, and interpretation-were seen to interact with elements of past and current family context, such as expectations, family dynamics, family of origin influences, and sociocultural change. The overall process involved parents' attempts to regain family equilibrium at different levels of adolescent autonomy and progress toward anticipated future teen changes in ways that either enhance or diminish family cohesion. / Master of Science
