- Description: The present study involves an exploration of the phenomenological expenence of posttraumatic growth in the context of a traumatic bereavement. An idiographic case study of a student who had witnessed her mother's death twelve years previously was conducted. Semi-structured interviews elicited data which was analysed using interpretative phenomenological analysis (IP A). Posttraumatic growth was found to have developed with regards to self-perception, relationships, and also in a broader spiritual and existential domain. The findings of this study shed light on the extant posttraumatic growth literature. In particular, findings were discussed in relation to the posttraumatic growth model as proposed by Calhoun and Tedeschi (2006). As posttraumatic growth is a relatively young concept, further research is needed in order to understand the meaning of reported growth more fully. While posttraumatic growth has been investigated in the context of bereavement, future research should distinguish more clearly between growth following traumatic and non-traumatic bereavement. Posttraumatic growth has received minimal empirical attention in South Africa, and therefore exploration of this area is suggested in the future. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Within South Africa (SA), eucalypts contribute significantly to the commercial production of pulpwood, treated poles, wood chips and saw timber. Due to their rapid growth and desirable timber properties, 47% of the afforested area within SA is planted with various eucalypts and their hybrid combinations. Biotic and abiotic factors pose a risk to the productivity of eucalypts, with the most significant risk currently associated with the increased impacts of foliar insect pests on tree productivity, for example Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae); Gonipterus scutellatus Gyllenhal (Coleoptera; Curculionidae); Thaumastocoris peregrinus Carpintero and Dellape (Hemiptera: Thaumastocoridae); Glycaspis brimblecombei Moore (Hemiptera: Psyllidae) etc. Past and current research has focused more on the individual components of biological, cultural and chemical control, with limited research conducted on the practical integration of these management strategies. Although the combination of biological and cultural control methods for long-term management would be preferred, the use of environmentally acceptable insecticides can contribute to the short-term management of insect pests where necessary. Environmental constraints (associated with forest certification) around the use of insecticides, means that there are currently few insecticides available for controlling foliar insect pests of eucalypts within the SA forest industry. Due to the recent increased introduction of insect pests, there is also a lack of data related to their impacts on tree growth, as well as the success of any management methods used. To improve our understanding regarding these components, three groups of trials (five in total) were implemented in the summer rainfall region of SA to quantify the impacts of insect pests on eucalypt growth, test integrated management practices (chemical and cultural management), and test environmentally acceptable insecticides. In 2010, two insect exclusion trials were established at Palm Ridge and Teza plantations in KwaZulu-Natal to quantify the impact of insect pests on two Eucalyptus hybrids. The trial locations were selected adjacent to compartments for which the pests Gonipterus spp. and Thaumastocoris peregrinus were present. Each trial had an insecticide treatment with an active ingredient of alpha-cypermethrin at a rate of 100 g l-1 and a control treatment where trees were not sprayed. Insect pests were collected after every spraying event. A greater number of insect pests were collected from the Palm Ridge site. Gonipterus spp. were the predominant insect pests collected. No significant growth differences were recorded between treated and untreated trees at Teza. Measurements taken at Palm Ridge indicated that insecticide-treated trees had significantly greater tree growth than untreated trees. Final measurements showed a v 25% reduction in volume for the control treatment compared to the insecticide treatment. Results of this study indicate that timing and duration of insecticide application could hold larger and additive benefits for insect exclusion. Due to the lack of non-hazardous registered insecticides, and the susceptibility of many of the eucalypts grown within SA to L. invasa, a trial was initiated in 2011 in Zululand (KwaZulu-Natal). A 3 x 4 x 4 factorial combination of 48 treatments were replicated 3 trials and arranged in a split-split-plot design. The factors included insecticide type as the whole plot (fenvalerate, azadirachtin and imidacloprid), timing of insecticide application as a sub-plot (0, 3, 6 and 9 months) and type of hybrid as the sub-sub-plot (a susceptible and tolerant E. grandis x E. camaldulensis hybrid (GC_s and GC_t) and a susceptible and tolerant E. grandis x E. urophylla hybrid (GU_s and GU_t)). To determine insecticide efficacy, plots of untreated clones were included as control treatments within each replicate. The incidence and magnitude of L. invasa damage and tree performance were assessed for up to 5.5 years of age. L. invasa damage recorded over the trial period indicated that irrespective of treatment, damage was lower in the GU clones than the GC clones resulting in a 63.9 m3 ha-1 volume difference at 5.5 years. In addition, the difference between the GU_s and GU_t clones (3.2 m3 ha-1) was marginal when compared to the GC_s and GC_t clones (37.2 m3 ha-1). A decrease in GC stocking correlated with the period when there was a high damage incidence recorded for L. invasa. Although the three insecticides tested delayed the onset of L. invasa damage, they did not result in improved tree performance at 5.5 years. Results indicate that the planting of a tolerant species (hybrid in this trial) was the most viable option for the management of L. invasa. Two trials were implemented in the KwaZulu-Natal Midlands in October 2016 (at Ingwe and Balgowan plantations), to test the efficacy of eight different insecticides (synthetic and organic) for the management of foliar insect pests. The Ingwe trial was planted with Eucalyptus dunnii and the Balgowan trial was planted with Eucalyptus badjensis. The insecticides tested were azadirachtin, deltamethrin, imidacloprid (liquid and tablet), Beauveria bassiana, Bacillus thuringiensis, potassium silicate and a combination of plant oil extracts (garlic oil, soybean oil and capsicum oleoresin extract). The imidacloprid tablet, deltamethrin and an untreated control were implemented as additional treatments. The insecticides were tested at the recommended rate (single rate) and at double the recommended rate (double rate), except for the insecticides in the additional treatments which were only tested at the single rate. These insecticides were applied three times over a period of four months, and tree growth measurements (Gld/Dbh and Ht) were taken four times over a period of seven months. Gonipterus spp. vi was the only insect pest found in both these trials, thus the insecticides were tested for their efficacy in managing this specific insect pest. A higher population and damage of Gonipterus spp. was found in the E. dunnii trial and very little to no damage was observed in the E. badjensis trial. All insecticides tested were not effective in managing Gonipterus spp. in these specific sites. A low population of insect pests and incorrect timing and method of application of some of the insecticides could offer a plausible explanation of results. Results from these trials indicate that where foliar insect pests occur in high abundance, significant tree-growth reduction occurs. Although insecticides (deltamethrin - for G. scutellatus; imidacloprid for L. invasa) can be used for the short-term control of these insects, their commercial benefits may be reduced due to the number of repeat applications required and/or with high levels of infestation. Of the eight environmentally acceptable insecticides tested for foliar insect control, the low abundance of insect pests present in the trials meant that their efficacy could not be quantified. If an alternative insecticide were to be found, its application would need to be linked to the environmentally stimulated outbreaks of specific insects. Of the treatments implemented, the selection and planting of eucalypts with known resistance to specific insect pests currently remains the most viable management strategy. Breeding for increased tolerance within resistant eucalypts may also provide additional benefits. Although the above research showed the negative impacts of foliar insect pests on tree growth, it also indicated that no single control method is viable for all insect pests. Future research should look at the integration of different management methods while incorporating more insect pests and different seasons in the study.

- Description: Research shows that the climate of Antarctica is changing and, it is vital that the change is monitored to understand how it will affect global ecosystems. Since the International Polar Year (IPY) 2007-2008, research in permafrost studies has grown. However, there are still existing gaps that impede complete understanding of Antarctic cold environments and landscape processes. Permafrost has been noted as one of the major controlling factors of the terrestrial ecosystem dynamics in Antarctica. However, the understanding of Antarctic permafrost, when compared to other cryospheric components, is limited, especially its thermal and physical properties, evolution, as well as links to pedogenesis, hydrology, geomorphic dynamics, and responses to global change. This project provided an understanding and insight to over-arching research that evaluates the state and status of permafrost and the active layer in Dronning Maud Land (DML) through examining short-term variations on ground thermal regimes. The main focus is on understanding the influence of synoptic, diurnal and seasonal events on the active layer in 2016. Analysis of available data shows that ground thermal regimes are influenced by variations in air temperature, pressure, wind speed and to some extent, relative humidity. Subsequently, ground thermal regimes also depend on soil physical characteristics including sediment particle size and bulk density. Furthermore, sediment particle size and bulk density have been found to have a great influence on thermal propagation rates as well as active layer depth; the higher the bulk density, the higher the thermal propagation rate and the lower the bulk density, the lower the thermal propagation rate. Conversely, a large proportion of bigger sediment particle size in soil corresponds with a higher thermal propagation rate and a large proportion of smaller sediment particle size in soil corresponds with a lower thermal propagation rate. Also, ground thermal regimes vary according to seasons. Ground temperatures are more variable in summer, while air temperatures are more variable in winter. The variability according to different seasons shows that the active layer responds to seasonal climatic variations. Additionally, the active layer also responds to synoptic and diurnal weather events.

- Description: Streams and riparian areas are tightly coupled through reciprocal trophic subsidies, and there is evidence that these subsidies affect consumers in connected ecosystems. Most studies of subsidies consider only their quantity and not their quality. We determined the bidirectional exchange of organisms between the Kowie River and its riparian zone in South Africa using floating pyramidal traps (to measure insect emergence) and pan traps (to capture infalling invertebrates).

- Description: The research examines the sedimentary environments and provenance of the Balfour Formation of the Beaufort Group (Karoo Supergroup) in the Eastern Cape Province, South Africa. This Formation occurs in the southeastern part of the Karoo Basin. It consists of sedimentary rocks, which are an alternating siltstone, shale and mudstone succession with subordinate interbedded sandstone and subsequently intruded by Karoo dolerite in the form of sills and dykes. ithostratigraphically, the Balfour Formation is subdivided into five units namely, from the base to the top, the Oudeberg, Daggaboersnek, Barberskrans, Elandsberg and Palingkloof Members. The Balfour Formation is overlain by the Katberg Formation. This study involved field investigations in the vicinity of the towns of Bedford and Adelaide with integrated stratigraphical, sedimentological and petrological studies. A geological map was constructed after field investigations. Lithofacies of the Balfour Formation that were studied are characterised by sandstone facies (Sh, Sm, St, Sr, Sp) and fine-grained sediments (Fl or Fsm) which reflect point-bar, cut-bank, channel and floodplain deposits. Lithologically, the Oudeberg Member consists of sandstone of which some units are internally massive alternating with thin laminated siltstone and mudstone. The Daggaboersnek Member is characterised by regular, generally non-lenticular, overall stratification, in the Barberkrans Member consists of sandstone lithosomes, while the Elandsberg Member is an argillaceous unit, similar to the Daggaboersnek Member. The Palingkloof Member is composed predominantly of red mudstone that can be used to distinguish the Balfour Formation from the overlying Katberg Formation, which consists predominantly of sandstone. The stratigraphic sequence displays two fining upward megacycles of sedimentary deposits with change in the sediment supply pattern from low-sinuosity to high-sinuosity river systems which reflect both braid and meandering deposits, respectively. Sedimentary structures in the sandstone units and the provenance of the Balfour Formation indicate that these deposits were produced by rivers flowing from the southeast with minor drift towards the northwest. According to the composition of the sediments and their sequence of deposition the Formation represents a fluvial environment. Mineralogical and grain size data from the sandstones of the various members of the Balfour Formation indicate the same source area of granitic, metamorphic and older sedimentary rocks and show no significant petrographic differences. The petrographic and geochemical investigations confirmed the sandstone to be feldspathic litharenite and ultralithofeldspathic sandstone. The palaeocurrent investigation indicates the main provenance to have been situated to the southeast of the Karoo basin. Heavy-mineral concentrations within the sandstones also give an indication that the source had a transitional arc plate tectonic setting.

- Description: The high elevated (ca. 1100 m) continental Kalahari Basin (KB) of southern Africa and the linked lower lying (ca. 400 m) Congo Basin (CB) of central Africa preserve in their interiors extensive sedimentary rock sequences and sediments that represent a unique record of the Phanerozoic geodynamic and climatic evolution of sub-Saharan Africa. In this thesis, field observations and new borehole data from the Democratic Republic of Congo (DRC) and Botswana are integrated with new paleontology and geochronology to present a substantially revised stratigraphy for the CB, and south-central Africa in general. This work also introduces a new multiphase model for the subsidence and uplift history of the CB, and improves correlations with the Cape-Karoo Basin (CKB) of South Africa and the Paraná Basin (PB) of south-east Brazil. Four deep boreholes, each between 2 and 4.5 km deep, drilled in the centre of the CB in the 1950’s and 1970’s are re-examined together with the colonial literature (in French) and available seismic data. This stratigraphic and basin analysis is complemented with new U-Pb dates of detrital zircons from core-samples of two of the boreholes (Samba and Dekese), as well as from samples collected during field work in the Kwango region of the south-west DRC. This work, for the first time, constrains the maximum ages and source provenances of the successions in the CB. Following the Pan African orogens (ca. 650-530 Ma), extensive sequences of red beds were deposited by regional paleocurrents to the south. These are now best preserved (1 km thick) along the West Congo, Oubanguides, and Lufilian Belts surrounding the CB. Overlying a hiatus that represents most of the early-Paleozoic, is a 1 to 3 km thick succession of easterly derived glacial, and then continental sequences of the Karoo Supergroup. This succession records the first main episode of subsidence [10-15 m/Ma], interrupted by a phase of uplift that is likely related to far-field intracontinental deformation within Gondwana supercontinent during the Variscan and Cape Fold orogenies (ca. 250-330 Ma) at its peripheries. Detrital zircons from the lower Karoo diamictites are dated at 1.85-2.05 Ga and 1.37- 1.42 Ga, and thus sourced from Paleoproterozoic (Eburnean) and mid-Mesoproterozoic (Kibaran type-I) basement rocks in Uganda and Tanzania. Zircons from all the other successions in the CB date predominantly at 950-1050 Ma and 500-800 Ma. These are derived from sediment recycling of late-Mesoproterozoic (Kibaran type-II) and late- Neoproterozoic (Pan African) sources in the Central African Republic (CAR) and Chad. A distinct unconformity across the Karoo Supergroup in the CB is overlain by 500- 1000 m Jurassic-Cretaceous sequences, here named the Congo Supergroup. During initial rapid subsidence [10-50 m/Ma], late-Jurassic (Kimmeridgian) shallow marine to continental sedimentation attests to a short transgression of proto-Indian Ocean waters into the northern CB (at 160 m above present day sea-level), succeeded by widespread deposition of aeolian dunes that extend from the southern CB to the PB in South America. The youngest zircons from these aeolian sediments in the CB date at 190 Ma and 240-290 Ma, and most likely indicate the influence of extensive silicic volcanic ash derived from the proto-Andes along the south-western margin of Gondwana. Two superimposed mid-Cretaceous (Albian-Cenomanian) lacustrine sequences in the central CB record a succeeding, slower [10-15 m/Ma], phase of basin subsidence during the opening of the South Atlantic (ca. 85-135 Ma). These Cretaceous sequences are in turn truncated by another regional peneplanation surface covered by Cenozoic (Eocene) silcretized sands and alluviums of the Kalahari Group, only 50-250 m thick in the centre of the CB. Southward, on top of the Kalahari Plateau in the central desert region of north-west Botswana, new boreholes intercepted laterally equivalent condensed lacustrine carbonates and calcretes (20-50 m thick) covered by sands. These terrestrial sequences are key archives of late-Mesozoic – Cenozoic paleo-climate changes, yet they remain stratigraphically unresolved. This new analysis of the Phanerozoic continental basins of south-central Africa and their equivalents in South America, opens a fresh continental-scale window into how West Gondwana break-up and concomitant epeirogenic uplifts of Kalahari (>2 km) and Congo (>200 m) are linked to interactions between the lithosphere and mantle geodynamics, and how these processes likely affected global climate changes.

- Description: This study evaluated the recruitment and selection of educators in the Zambezi Education Directorate of Namibia. Its objectives were: (1) to investigate ways and means of facilitating the implementation of the Public Service Act (Act no. 13 of 1995) with regard to the recruitment and selection of educators in the Zambezi Education District of Namibia; (2) to assess the role played by environmental and contextual factors in the performance of officials responsible for recruitment and selection of educators in the Zambezi Education District of Namibia; and (3) to find out if there was a relationship between the high turnover of educators and the processes of recruitment and selection of educators during the period of the investigation. A qualitative research methodology was used to conduct the study. A sample of 21 participants was selected for the study. It was comprised of six officials from the division human resources management - responsible for receiving information about teachers needed in schools from the circuit offices and advertising vacant posts; six officials from division of professional services - responsible for ensuring that educators who are recruited possess the prescribed teaching qualifications and competences; two officials in management cadre - responsible for administrative and financial decisions on recruitment and selection of educators and ensuring that posts have been budgeted for before they are filled. Seven participants who were former employees of the Zambezi Education Directorate also formed part of the sample. The researcher used interviews to gather data from participants. He also consulted relevant official documents such as the Public Servant Staff Rules (PSSR), circulars and policies issued by the Office of the Prime Minister (OPM) the Public Service Act, (Act No. 13 of 1995) and the Education Act, (Act No. 11of 2000). The study found, among others, that some participants who were involved in the recruitment and selection processes were not aware of the relevant Recruitment and Selection Policy. The environment and the context in which the recruitment and selection policy was implemented created loopholes for inefficiency and ineffectiveness. Furthermore, the study found that there was a relationship between the turnover of educators and the processes of recruitment and selection of educators. Hence the study recommends various ways and means of improving the recruitment and selection process in the Zambezi Education Directorate.

- Description: This thesis attempts to evaluate the role of the World Bank in Sub-Saharan Africa's development. It argues that the World Bank has stepped beyond the boundaries of a typical lending institution by linking its aid to political reform. The study argues that in this capacity the Bank has contributed to the halting democratization process currently underway in Africa. The economic effects of the World Bank's Structural Adjustment Programmes have been less successful. As yet, the programmes have not produced the expected results and there is no evidence of long-term, sustainable economic recovery in Sub-Saharan Africa. These programmes are, however, long-term strategies and it may therefore be too premature to reach a final conclusion. They may also have been affected negatively by unfavourable political environments. This study, noting the negative effects of the international terms of trade and prices for African exports, concludes that although economic recovery in Sub-Saharan Africa will be facilitated by domestic political and economic policy reform, there is also a need for reform of the international economic order. The World Bank has correctly identified the need for domestic improvement, but it has a tendency to disregard the negative consequences of the existing structure of the international economy.

- Description: Continental flood basalts are usually regarded as a single tectonomagmatic entity but frequently quoted examples exhibit a variety of tectonic settings. In one well-studied, classic, flood basalt province, the Mesozoic Karoo province of southern Africa, magmatism occurred in the following tectonic settings: (a) continental rifting leading to ocean-floor spreading in the South Atlantic Ocean (Etendeka suite of Namibia); (b) stretched continental lithosphere and rifting not leading directly to ocean-floor formation (Lebombo suite of southeastern Africa); and (c) an a-tectonic, within-plate, continental setting characterized by an absence of faulting or warping (Lesotho highlands and Karoo dolerites of South Africa).

- Description: While this study is partly theoretical it includes an exploratory case study in which theoretical insights are applied. In the theoretical part of this study, criteria for a successful poverty alleviation project were developed, guided by sustainability theory and complexity theory. It was proposed that researchers could assess existing projects according to these criteria to show where they were successful and where they could improve. The second part of this research consists of a case study, where an actual poverty alleviation project (The Nomzamo Special Care Centre, Peddie, Eastern Cape) was assessed according to the criteria developed in the first part. For this exploratory case study a non-random sample of 9 participants was drawn from the Nomzamo Special Care Centre and other stakeholders in the Ngqushwa Local Municipality in the Eastern Cape. Data was collected using questionnaires, observation and interviews. The results obtained from analysis indicate that project members particularly experience challenges pertaining to financial resources, infrastructure and maintenance. It is recommended that project members receive assistance from the government departments in order for the project to remain sustainable.

- Description: South Africa has been experiencing service delivery protests especially in the African communities. These protests are a manifestation of conflict and dissatisfaction of communities in the ruling party in government. In order to reduce conflict, it is critical that the ruling party in government addresses the basic needs of these communities as the people start to lose confidence in the government. The study seeks to investigate whether service delivery protests could be prevented through improved provision of basic services in the communities, focusing in the New Brighton Township community, in Nelson Mandela Bay Municipality as the area of study. The provision of basic services is important for the livelihood of any community. The study analyses the extent to which poor service delivery can lead to community conflicts or revolt against the ruling party in government. Some areas of New Brighton Township community are experiencing a backlog of basic service delivery. Members of this targeted community fall within the previously disadvantaged category and expected the ruling party in government to meet their basic service needs. Chapter one provides an introduction which gives a brief overview of the study, problem statement, aims, research objectives and questions, preliminary literature review and research methodology to be employed by the study. Chapter two provide a literature review of community conflicts in relation to basic service delivery needs and peoples’ expectations. Chapter three provide the legislative framework for the developmental local government and the role of section/chapter nine (9) institutions especially the Public Protector’s role in relation to conflict. Chapter three will also provide reasons for the establishment of Local Municipalities. Chapter four provides proposals for the approaches and strategies to eliminate conflicts and policy implications. The chapter also provide an analysis of the participants’ responsesfrom the questionnaires. Chapter five will be a summary with concluding remarks and recommendations, as proposals with mitigating measures arising from the research.

- Description: Unemployment is an urgent socio- economic issue facing not just Sub-Saharan Africa but also the global world at large (Yu, 2013). Globally, the International Labour Organisation (ILO) estimates that 201 million people were unemployed in 2014. Almost 74 million of those unemployed were young people (aged 15-24) in 2014. The ILO report further states that the number of people seeking employment was over 30 million more than in 2008, because several people lost their jobs due to the world economic recession. One of the results recorded from the ILO’s World Employment and Social Outlook 2016, show that youth unemployment is still three times that of the adult unemployment rate at 13.1% (ILO, 2016). Unemployed youths are estimated to be 73.3 million, a 3.3% decline from the global crisis in 2008 (ILO,2016:6). Crisp and Powell, (2016) indicate youth are vulnerable due to the economic fragility of the labour market and uneven recovery over the past years.The case of Sub-Saharan Africa is no different. South Africa is one of the countries grappling with high rates of unemployment, especially among youths (Burger & Fintel, 2009). According to a report by Statistics South Africa in 2015, 5.2 million of the labour force were unemployed, while 15.1 million South Africans are not economically active- resulting in an unemployment rate of 24.5% in the fourth quarter of 2015 (Statistics South Africa, 2015). Since- 2010, the first quarter of each year recorded increases in unemployment levels. The number of unemployed individuals had increase by more than half a million (626000, 521000) in the first quarter of 2015 and 2016 respectively (Statistics South Africa, 2016). The youth unemployment rate in South Africa decreased to 47.60% in the third quarter of 2016 from 53.70% in the second quarter of 2016.

One of the results recorded from the ILO’s World Employment and Social Outlook 2016, show that youth unemployment is still three times that of the adult unemployment rate at 13.1% (ILO, 2016). Unemployed youths are estimated to be 73.3 million, a 3.3% decline from the global crisis in 2008 (ILO,2016:6). Crisp and Powell, (2016) indicate youth are vulnerable due to the economic fragility of the labour market and uneven recovery over the past years.The case of Sub-Saharan Africa is no different. South Africa is one of the countries grappling with high rates of unemployment, especially among youths (Burger & Fintel, 2009). According to a report by Statistics South Africa in 2015, 5.2 million of the labour force were unemployed, while 15.1 million South Africans are not economically active- resulting in an unemployment rate of 24.5% in the fourth quarter of 2015 (Statistics South Africa, 2015). Since- 2010, the first quarter of each year recorded increases in unemployment levels. The number of unemployed individuals had increase by more than half a million (626000, 521000) in the first quarter of 2015 and 2016 respectively (Statistics South Africa, 2016). The youth unemployment rate in South Africa decreased to 47.60% in the third quarter of 2016 from 53.70% in the second quarter of 2016.

- Description: Patients who are critically ill get often admitted to intensive care units (ICUs). The majority of these patients require support with their breathing and are thus connected to a mechanical ventilator. One aspect to consider in the mechanically ventilated patient is endotracheal tube cuff pressure (ETT) management. The management of ETT cuff pressure entails that nurses working in ICUs have the responsibility of ensuring that ETT cuff pressure is kept within normal range of 20-30 cmH20 for the safety of the patients in order to avoid complication of over and under inflation. Poor management of ETT cuff pressure places the mechanically ventilated patients under risk of tracheal injury. Tracheal injury may also be caused by over or under inflation of the ETT cuff. Over inflation of the ETT cuff can lead to the occlusion of capillaries lining the trachea at the cuff site, tracheal stenosis, and can also lead to the death of mucus membranes around the area, just to mention a few. On the other hand, under inflation of the ETT cuff, can lead to air leaks as well as aspiration of gastric contents into the tracheal tree. Therefore, in order to maintain ETT cuff pressure within normal ranges, evidence-based guidelines related to the management of ETT cuff pressure should be used. However, in Malawi the management of endotracheal tube cuff pressure in mechanically ventilated adult patients by nurses in ICUs is not well explored and it is not clear whether this practice is based on evidence-based guidelines. Furthermore, strategies on how to implement evidence-based guidelines in the ICU might not be known and poorly defined because of the complexity of the context. The study is therefore aimed at implementing and evaluating the effect of an evidence-based guideline on the management of ETT cuff pressure in mechanically ventilated adult patients by nurses in ICUs in Malawi using active (printed educational materials and monitoring visits) and passive (printed educational materials only) implementation strategies. The research study used a quantitative approach with multi-designs. Four phases were used in order to achieve the four objectives that were set. Phase one was the pre-test and used a survey design, two was the expert panel review of the evidence-based guideline, three was the implementation of the reviewed evidence-based guideline using a randomised controlled trial design and phase four was the post-test which used a survey design. The RCT included 25 participants from the control and 27 from the intervention group. Each group had three ICUs of which one in each group was from a private hospital and the other were government. Data collection in phases one and four was by a hand delivered pre-and post-questionnaire. In phase two the expert panel members with experience in critical care used the AGREE II Instrument to review the evidence-based guideline that was implemented. In order to gather data during the monitoring visits, the researcher recorded field notes. The applications that were developed by the University statistician consultant using visual basic applications in excel were used to analyse data. Two different implementation strategies were used to implement the evidence-based guideline. The control group used passive implementation strategy which was printed educational materials thus the evidence-based guideline and algorithm. The intervention group used both active and passive implementation strategies which was the printed educational materials thus the evidence-based guideline and algorithm plus monitoring visits by the researcher. In order to establish the effect of the implemented evidence-based guideline on the nursing care practice for the management of endotracheal tube cuff pressure an evaluative posttest survey was conducted in phase four of the research study. The results revealed that the majority of participants had gaps in both groups regarding nursing care practice for the management of endotracheal tube cuff pressure for the mechanically ventilated adult patients in the pretest but improved in the posttest. In the control group 52% had very low knowledge score, 16% had low score, 28% average, and 4% high score while in the category of very high score there was nobody. However, in the posttest those in the very low score were only 44% while the percentage in the low score remained 16%. There was an improvement in the average scores in the posttest such that only 44% were in this category. There was no one in the high and very high score in the pretest. On the other hand, in the intervention group, 78% had a very low score, 9% low score, and 13% were in the category of average score, while in the high and very high score category there was zero percent in the pretest. However, there was also an improvement in the posttest such that only 44% a very low knowledge score. But 19% had a low score, there were 37% in the average category and no one was in the high and very high score. Statistical analysis revealed that the results were not significantly different between and within groups. Improvements were observed in the two groups regarding the scientific knowledge scores for the nursing care practices in the posttest. Upon qualitative analysis of the data from the open-ended question, two main themes emerged thus the need for documentation of endotracheal tube cuff and the process of implementation the evidence-based guidelines. Sub themes such as lack of documentation; no part of routine care and monitoring not done at all were identified under the main theme of the need for documentation of ETT cuff pressure. The Guideline itself need to be clear; implementation strategies; follow up; incentives; supervision; incentives; time factor; resources or equipment required for successful implementation; nurses buy-in critical for the implementation; training detrimental to EBP implementation; nurses attitude crucial to implementation of EBGs and knowledge of nurses for guideline essential for the implementation were the sub themes identified under the main theme of the process of implementing the evidence-based guideline. All appropriate ethical considerations such as principles of autonomy and self-determination, confidentiality and anonymity, voluntary participation, right to receive treatment, informed consent, were adhered to throughout the research study. The research study was unique in nature because it was the first of its kind in Malawi and it contributed to the awareness of the recommended practice for management of endotracheal tube cuff pressure in the ICUs in the country by implementing an evidence-based guideline. The unique contribution of the study is that it is a challenge to implement evidence-based guideline in poor and resource constraint countries like Malawi.

- Description: It is estimated that 80 percent of nurses experience some type of bullying in the workplace during their working lives, and bullying from colleagues has become a major concern. Bullying involves repeated forms of negative behaviours directed at a victim over time. More specifically, the victim is bullied repeatedly over time, with bullying ranging from mild to more severe forms that often go unreported. Bullying in the workplace may cause low self-esteem, depression and anxiety, physical illness and in some cases, the inability to work. The aim of this research study was to explore and describe community service professional nurses’ experiences of being bullied in state hospitals. The information gathered during the course of the study was used to develop strategies that can prevent the bullying of community service professional nurses in the workplace. The design of the study was qualitative, exploratory, descriptive, and contextual in nature. The population sample included all community service professional nurses in state hospitals in the Nelson Mandela Bay area. The researcher employed purposive sampling to select participants from the population of community service professional nurses employed at state hospitals. She collected data by conducting semi-structured individual interviews to gain in-depth accounts from participants and by making observations, which were captured in field notes. Data collected during the interviews were transcribed verbatim and analysed according to Tesch’s eight steps of analysis. Themes were identified through this process and compared to relevant literature. The researcher used the services of an independent coder to aid in the coding process. Trustworthiness was ensured by following Lincoln and Guba’s model of trustworthiness, which comprises the following concepts: credibility, transferability, dependability, and conformability. The researcher ensured that the study adhered to high ethical standards through the principles of justice, beneficence, non-maleficence, and respect for people.

- Description: The primary objective of this research study was to strategically analyse the meaning of work for fashion retail industry employees with the aim of developing a calling orientation to work.A sample of 84 fashion retail industry employees from Port Elizabeth, South Africa indicated their perception of callings in work; the pathways to callings in work and job satisfaction. Furthermore, fashion retail industry employees also indicated their use of job crafting techniques as a tool to foster meaningful work. This is one of the first studies conducted on callings in work in the fashion retail industry.Findings of the study indicated that although on average fashion retail industry employees are neutral about having a calling orientation to work, 24-27% indicated to having a calling orientation to work. Furthermore the study showed that there is a positive correlation between 1) transcendent guiding force; 2) value-driven behaviour and sense and meaning; 3) identification with one’s work and person-environment fit and a calling orientation to work. The study also indicated that the presence of a transcendent guiding force and job satisfaction are the two independent variables that are influential in achieving calling orientation to work for fashion retail industry employees of Port Elizabeth. Implications and recommendations from this study are outlined.

- Description: Feedbacks between abiotic variables and community structure in Antarctica are poorly understood. Research is, therefore, required to elucidate the patterns of biodiversity that exist and the factors that influence them, particularly under changing climates. Landscape processes affect environmental heterogeneity, which in turn affect patterns of biodiversity. Two inland Antarctic nunataks, Robertskollen and the Northern Buttress of Vesleskarvet, were selected for investigation to determine the potential impact of selected environmental factors on lichen distribution and abundance, at the intra- and inter-nunatak scales. Lichens were found to prefer rock faces with dips between 1° and 45°, and northern/southern aspects. Lichen colonisation was mostly in microtopographical features that result from rock weathering. The distribution of lichens was found to be regular at the intra- and inter-nunatak scale, whereas lichen abundance was found to be mostly influenced by temperature. On the Northern Buttress, rock hardness displays a similar pattern to lichen abundance, both of which are suggested to be a function of exposure time, which is dependent on deglaciation. The two nunataks serve as excellent laboratories that can potentially be used as proxies for investigating the possible impacts of climate change
