Cross-sectional study investigating the exercise behavior, preferences, and quality of life of primary brain tumor patientsEngelbrecht, Adel 25 July 2012 (has links)
Brain tumors are the second leading cause of cancer deaths in young adults ages 20- 39. (Armstrong et al., 2004) According to the South African Medical Research Council, there was an estimate 801 deaths because of brain cancer in South Africa in 2000. If these statistics are compared to other types of cancers like breast-, lung- and prostate cancers, is the prevalence of the diagnoses of brain tumors, a very small percentage. According to the Mayo clinic in South Africa, the estimate number of brain tumor incidences was 3% in 2007. Despite of these statistics with regards Brain tumors, one in six South African men and one in seven South African women will be diagnosed with cancer during their life times. Despite this small percentage, the diagnoses of brain tumors have escalated the last few years. The reason for these new statistics is still unknown. With exercise that is becoming one of the most important adjuvant therapies for most diseases or illnesses, we may sustain this idea of using exercise intervention as an adjuvant therapy for brain tumor cancers we can prove this through many researches that has been done in the last few years. (Schwartz, 2003) Studies done by different researchers they found that exercise intervention is becoming increasingly recognized as a safe, feasible and beneficial supportive therapy for cancer patients both during and after the cessation of adjuvant therapy. (Jones et al., 2006) Exercise influences a lot of different systems in the body, to the advantage of the cancer patient (Schwartz, 2003) and emerging new research shows that physical exercise may boost brain function, which include improve mood. (Kong, 1999) Exercise, according to Cotman and Berchtold (2002) is commonly believed to be a behavioral strategy to relieve stress, and reduce depression and anxiety in humans. Exercise intervention further influence following aspects of the human body, namely brain deprived neurotrophic factor (BDNF) and 5-HT (Serotonin). Improvement of these could, in fact, lead to a better quality of life (QoL) of a brain tumor patient (Cotman&Berchtold, 2002). Fatigue that sets in, due to the different cancer therapies, is also a factor that has an affect on depression and anxiety of the patient. Keeping still and rest to prevent fatigue were followed in previous regiment when working with cancer patients was followed. This approach, in fact, has a very negative effect on the patient. Being diagnosed with a brain tumor the patient will never be emotionally prepared for this type of information and it usually shatters their sense of well being and their personal security. All of these factors, especially depression, affect the patient’s QoL. (Vaynman et al., 2004) An exercise regiment for brain tumor patients has not yet been developed properly, because exercise intervention for familiar cancers could be problematic and not suitable for brain tumor patients. (Schwartz, 2003) Therefore, the purpose of this study is to further the knowledge and the field of expertise of exercise as an adjuvant therapy in brain tumor patients to better QoL over a larger period of time. AFRIKAANS : Die tweede grootste leier in siektes tussen die ouderdomme van 20-39 jaar wat lewens eis is Brein gewasse (brein kanker). (Armstrong et al., 2004) Volgens die Suid- Afrikaanse Mediese Navorsingraad, is daar tot 801 gevalle van breingewas sterftes in die jaar 2000 aangemeld. As hierdie statistieke vergelyk word met statistieke van kanker wat meer prominent voorkom soos byvoorbeeld bors-, long-, en protaatkanker, lyk die voorkoms van breinkanker diagnosis maar na ‘n baie klein persentasie. Die Mayo Kliniek in Suid-Afrika het in 2007 bevind dat die voorkoms van breinkanker in Suid-Afrika ‘n persentasie van 3% uitgemaak het. Ten spyte van hierdie statistieke betreffende breingewasse, sal een uit elke ses mans en een uit elke sewe vroue, gediagnoseer word met een of ander kanker gedurende hulle leeftyd. Alhoewel die persentasie wat reeds genoem is maar na ‘n klein hoeveelheid lyk, het die voorkoms van breingewasse baie toegeneem in die laaste paar jaar en selfs maande. Die rede vir hierdie aansienlike toename is steeds onbekend. Oefening word al hoe belangriker en word al hoe meer deur verskeie dokters voorgeskryf om te dien as ‘n bykomende behandeling vir verskeie siekte toestande. Dit word veral ook vir kanker pasiënte voorgeskryf. Oefen intervensie kan dus gebruik word vir breinkanker pasiënte, hierdie stelling gestaaf kan word, aangesien daar verskeie navorsings reeds bewys het dat oefening as bykomende terapie gebruik is vir kanker pasiënte. (Schwartz, 2003) Hierdie studies het bevind dat oefening as ‘n veilige, uitvoerbare en voordelige bykomende intervensie vir kanker pasiënte erken word. Hierdie intervensie kan tydens en na hoof kanker behandeling gebruik word (Jones et al., 2006). Oefening beinvloed verskeie sisteme in die liggaam, tot voordeel van die kanker pasiënt. (Schwartz, 2003) Nuwe navorsing het ook aan die lig laat kom dat fisieke aktiwiteit ‘n persoon se breinfunksie bevorder, wat onder andere ‘n baie groot invloed het om die pasiënt se gemoedstoestand. (Kong, 1999) Volgens, Cotman and Berchtold (2002), is daarvolgens studies bewys dat oefenterapie ‘n manier is om stres te verlig, sowel as depressie en angstigheid in meeste mense. Oefenterapie beinvloed ook die volgende aspekte positief in die menslike liggaam naamlik, Brein ontnemende neurtrofiese-faktor (BDNF) en 5-HT (Serotonien). Verbetering van hierdie faktore, kan ly tot ‘n beter kwaliteit van lewe van ‘n pasiënt wat met ‘n breingewas gediagnoseer is (Cotman&Berchtold, 2002). Uitputting (moegheid) wat gewoonlik intree as gevolg van kanker terapie, is ook ‘n faktor wat ‘n effek het op die depressie- en angsvlakke van ‘n pasiënt. In vroeë behandelingsprotokol van kankerpasiënte, moes die pasiënt so stil as moontlik verkeer om sodoende uitputting of moegheid te voorkom. Hierdie benadering het in die uiteinde ‘n baie negatiewe effek op die pasiënte tot gevolg gehad. ‘n Persoon wat met ‘n breingewas gediagnoseer word sal nooit emosioneel voorbereid wees op hierdie diagnose nie en sodoende kan dit lei tot ‘n ineenstorting van die persoon se geestestoestand en persoonlike sekuriteit. Hierdie “ineenstorting” kan ‘n groot invloed hê op die kwaliteit van lewe van hierdie pasiënt (Vaynman et al., 2004). ‘n Oefenintervensie protokol vir breinkanker pasiënte is nog nie voldoende vasgestel nie, aangesien oefenterapie intervensies wat vir bekende kankers problematies en selfs gevaarlik kan wees vir breingewas pasiënte nie. (Schwartz, 2003) Daarom is die doel van die studie, om inligting te verkry en kennis in te samel om die veld van deskundiges uit te brei om sodoende ‘n oefenterapie protokol neer te lê vir breinkanker pasiënte. Hierdie protokol sal dus dien as ‘n bevordering van kwaliteit van lewe van hierdie pasiente deur middel van oefen intervensie as bykomende behandeling.

Riglyne vir die effektiewe assessering van dosente in hoër onderwys binne die nasionale kwalifikasieraamwerk / Johannes Marthinus JacobszJacobsz, Johannes Marthinus January 2003 (has links)
This study focuses on the composition of guidelines for the effective
assessment of lecturers - hence the emphasis is on the principle that
assessment may be regarded as indispensable for professional development
and for making a meaningful contribution towards ensuring quality in the context
of the National Qualification framework.
To this end a literature study was firstly undertaken regarding the nature of and
criteria for effective assessment. The literature indicated that a variety of
changes took place in South Africa since 1994, amongst others in the area of
education, training and development. There have been numerous debates
about this on stages and in political council halls, schools, colleges, technikons,
universities, the press and the general workplace. Often the debates also
centred on the low levels of competence and performance of workers in South
Africa. Sometimes even the abilities, competence and performance levels of
graduates and diplomandi have been questioned. In the context of these doubts
people started investigating the role played by higher education, and more
specifically lecturers, in ensuring that competent human resources leave the
higher education environment for the professional world. As a result the
purposeful assessment of lecturers has been identified as imperative.
Furthermore, certain important factors that may influence the nature of and
criteria for assessment, are discussed in this study. These include, amongst
others, issues such as the education and training system, outcomes-based
education and training, competence, knowledge escalation, the assessment of
competence arid performance, the professional development of the lecturer, the
concept assessment, the relation between assessment and ensuring quality,
Bloom's taxonomy, different assessment instruments, the management of
quality and the appointment of lecturers.
The assessment of lecturers is viewed from a development-oriented
perspective, where the focus is on continuous assessment that may be
beneficial for individual, professional and organisational development. It is
shown that a variety of qualitative and quantitative assessment instruments may
be optimalised during formative as well as summative assessment, with which
the training, needs, abilities, skills, competencies, capacity and performance of
lecturers may be determined. The assessment of lecturers is regarded as a
contributing factor in delivering and ensuring quality. It is also shown that the
process should be undertaken in a managerial manner in order to continuously
promote quality.
Thereupon a discussion of assessment practices follows. In this discussion the
focus is on the roles of lecturers in government-supported higher education
institutions. The discussion is guided by the context which is determined by the
implementation of the principles of the National Qualification Framework. A
number of actors are identified who are directly or indirectly involved in the
assessment of lecturers' competencies, outputs and performance in the higher
education environment. It is also indicated that the implementation of the
National Qualification Framework is guided by a number of legislations of which
government-supported higher education institutions must give account in the
performing of their tasks and functions.
From literature it is clear that countries like the United Kingdom, the USA,
Australia and New Zealand use assessment practices to ensure quality in the
higher education environment. The role of the lecturer in that process is
highlighted, and it is indicated that the assessment of the lecturer is indirectly
addressed in the process.
An empirical study was performed to establish, in the first instance, whether
lecturers have been subjected to effective and appropriate training regarding
the implementation of the National Qualification Framework. The second
objective of the empirical study was to identify the implications of the
assessment of lecturers attached to government-subsidised or public higher
education institutions for all stakeholders.
It is found in this study that a distinction should be made between the
competence and performance assessment of lecturers. In addition it is indicated
that the competence certification of lecturers must be regarded as imperative in
order to facilitate performance-oriented functioning in the higher education
environment. It is also found that lecturers must to a large extent cope with the
process of giving account of all the new legislations and resulting expectations -
sometimes under great pressure and amidst uncertainty and insufficient
competence levels because of inadequate training, assessment and feedback.
As a result lecturers do not experience the implementation of the National
Qualification Framework as effective.
In order to accommodate the changed and changing environment of the higher
education sector, a conceptual model is composed to serve as a guide for the
assessment of lecturers. In this model it is indicated that systems being
developed for the assessment of lecturers should make provision for and
account for a variety of factors, such as quality, primary and secondary actors,
legislation, and the abilities, skills, competencies, capacity and performance
levels of lecturers, assessment instruments, proactive, reactive, formative,
summative, qualitative and quantitative assessment interventions. The
synchronization and purposeful structuring of these factors may make a
contribution towards creating a context which is beneficial to the professional
development of the lecturer and consequently to performance in the higher
education system. / Thesis (Ph.D. (Education))--Potchefstroom University for Christian Higher Education, 2003

Managing mobile learning in a higher education environment / Olivier V.Olivier, Vanessa January 2011 (has links)
The aim of this study is to conduct a thorough theoretical study on mobile learning (mlearning)
in order to achieve the primary objective of the study which is to develop a general
framework to implement and manage mobile technologies in a higher education
environment.
The focus of the literature study was to research the state of mobile technologies and their
relevance to teaching and learning. The literature study investigate the implications of mobile
technologies for students, lecturers and thus for the institution and provided an overview of
frameworks found in literature with the emphasis on the management of m–learning within
the higher education institution.
M–learning is part of a new mobile conception of society, with the mobility of the
technologies impacting on the mobility of the students, the lecturers and ultimately on the
mobility of higher education. Literature suggests that, while m–learning is proving to be
innovative, the factors that most strongly impact on the ultimate success or failure of mlearning
will depend on human factors, the balancing of technological ideals and
pedagogical imperatives, and the successful management of the interface between human
educational systems and technology systems. The proposed general framework focuses
on addressing key issues related to m–learning from the perspective of the student, the
lecturer and thus the institution. In order to remain competitive higher education needs to be
diligent in maintaining the complex technology infrastructure that supports a thriving
mobile culture that will meet and exceed the expectations of both lecturers and students.
The empirical research conducted had as objectives to investigate the mobile technology
assets of respondents with regard to the hardware and the software that they own, the mobile technology actions of respondents in regard to what they do with the mobile
technology that they own and to investigate the respondent's attitude towards mobile
technologies. A survey was designed and distributed to a sampling of the academic staff
and students of the North–West University (NWU) in South Africa, specifically the
Potchefstroom Campus.
There is ample proof from the empirical study that there is a gap with regard to the level of
accessibility, usage, and attitude with regards to the different interest groups in the higher
education environment. Higher education institutions should invest in investigating these
gaps further and in leveraging off the benefits of the effective management of these
technologies to improve teaching and learning.
The final chapter concludes with a summary of the secondary objectives researched in the
literature (Chapter two) and empirical research (Chapter three) chapters in order to support
recommendations towards the primary objective of this study. The rapid pace of adoption
and advancement of mobile technologies creates opportunities for new and innovative
services provided through such mobile devices. Higher education finds itself in the early
innings of the mobile Internet pulling both lecturers and students towards the same place:
smaller, faster, cheaper devices working together in a web of connectivity.
Recommendations were made in this final chapter on how higher education institutions can
leverage the benefits of the effective management of mobile technologies to improve
teaching and learning. M–learning has the potential to increase the capacity of higher
education through improving efficiency and productivity of teaching and learning. Mlearning
could address challenges related to quality of teaching such as continuous
professional training, lifelong upgrading, connecting with academics worldwide and
communicating effectively with students. Higher education is discovering the potential of mlearning
to promote student engagement and improving the quality of learning.
Management of higher education institutions and systems, management of policymaking
including storage and analysis of data, construction and assessment of policy scenarios, and
tracer studies or academic tracking systems can be improved through the use of m–learning.
Mobile technologies will continue to increasingly become an integral part of students' and
lecturers' private and day to day lives and m–learning will be integral in educational content
delivery. Additional research is required to study the effective and optimal implementation of
m–learning. A better understanding of the benefits and leverage thereof is required and
additional research should provide answers to these questions. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2012.
