Enhancing Effective Implementation of Recommendations for the Saving Mothers Report in Maternity Units of Limpopo Province, South Africa

Mothapo, Kobela Elizabeth 20 September 2019 (has links)
PhDH / Department of Advanced Nursing Science / Background: The National Committee for the Confidential Enquiries into Maternal Deaths recommend the implementation of “Saving Mothers’ recommendations” as a measure to reduce maternal deaths. However, this objective has not been achieved because the Maternal Mortality Rate in South Africa was standing at 134.33/100 000 live births and Limpopo Province at 165.16/100 000 live births. The national target for reduction of maternal mortality was 20% for all provinces for 2016. Limpopo Province’s reduction was below 12.5% for 2016. Purpose: The purpose of the study was to develop a strategy to enhance the implementation of the Saving Mothers’ recommendations in the maternity units of Limpopo Province. Methods: The convergent parallel design was used in this study. The study was conducted in phases, namely: Phase 1(a) was a qualitative research approach and a non-experimental, descriptive and exploratory design. The population consisted of district managers who were managing the Maternal Health Services and registered midwives who were working in the maternity units of Limpopo Province. Non-probability purposive sampling was used for both the district managers and the registered midwives. Data were collected using a central question for the managers managing Maternal Health services which was “What support are you giving to facilitate the implementation of the recommendations by the Saving Mothers Report?” and the question for the registered midwives was “What challenges are you experiencing when implementing the Saving Mothers’ recommendations.” Tesch’s open-coding technique was used to analyse qualitative data. Trustworthiness was ensured through credibility, confirmability, dependability, transferability and authenticity. Phase 1(b) was a quantitative and a non-experimental descriptive design. The population comprised of 200 patients who were included in the study. Questionnaires were developed and used to collect ABSTRACT vi data. Data was analysed using the Statistical Package for Social Sciences (SPSS, version 24.0) with the assistance of the statistician. Discussion of data were done in an explanatory sequential way where data from Phase 1a was discussed and supported by data from Phase 1b. Findings: The themes that emerged were: Challenges related to implementation of the recommendations of the Saving Mothers Report in maternity units, Description of existing training programmes and in-service education for health care professionals, Knowledge on implementing recommendations for the Saving Mothers Report when providing care in maternity units and Suggestions related to improvement of adherence to recommendations for the Saving Mothers Report in maternity units. Some of the themes were supported by the quantitative results whilst some not supported. Validity and reliability were ensured by giving the questionnaires to experts on the subject, colleagues and promoters to analyse and determine if items adequately represent content in the correct proportion. Ethical considerations were ensured by obtaining ethical approval from the University of Venda Ethics Committee and permission to access the facilities from the Limpopo Province Department of Health. The participants signed informed written consent. Phase 2 entailed strategy development and validation of the developed strategy. Recommendations: The recommendations included that the Department of Health should employ more staff and put operational managers in permanent positions. Sufficient equipment and supplies essential for maternal health care and maternal health infrastructure should be procured and a good plan for the managing thereof implemented. It is also recommended that health care workers should work hand in hand with the community structures and the ‘mosate’. / NRF

Vliv dynamického strečinku na výslednou dynamiku dolních končetin u volejbalistů / Influence of dynamic stretching on the resulting dynamics of lower extremities in volleybal

Hons, Ondřej January 2017 (has links)
Title: Influence of dynamic stretching on the resulting dynamics of lower extremities in volleyball Objectives: The aim of this work was to find out if there is a correlation between long term dynamic stretching and muscle dynamics of lower limbs of volleyball players. Methods: Theoretical part is based on foreign literature and researches. To gain the necessary data, experimental study was created. It contained 10 male probands in the age of 16-19. In the beginning of the experiment, all the participants attended the Bosco test at the biomedical lab at UK FTVS. The main parameter was the total flight time of the entire 60 seconds. After that participants attended 8 weeks of 2 times a week of dynamic stretching before the training instead of their usual stretching stereotype. Immediately after those 8 weeks, second Bosco testing took place and the comparison of the data of the whole group and individuals was made from the view of their volleyball posts. Results: There was a slight improvement in all the data at the whole group and significant improvement in anaerobic endurance. After comparing of the results of all the probands no significant differences between the probands from the perspective of player's volleyball posts. Keywords: volleyball, stretching, static stretching, dynamic stretching,...

Usable privacy for digital transactions : Exploring the usability aspects of three privacy enhancing mechanisms

Angulo, Julio January 2012 (has links)
The amount of personal identifiable information that people distribute over different online services has grown rapidly and considerably over the last decades. This has led to increased probabilities for identity theft, profiling and linkability attacks, which can in turn not only result in a threat to people’s personal dignity, finances, and many other aspects of their lives, but also to societies in general. Methods and tools for securing people’s online activities and protecting their privacy on the Internet, so called Privacy Enhancing Technologies (PETs), are being designed and developed. However, these technologies are often seen by ordinary users as complicated and disruptive of their primary tasks.   In this licentiate thesis, I investigate the usability aspects of three main privacy and security enhancing mechanisms. These mechanisms have the goal of helping and encouraging users to protect their privacy on the Internet as they engage in some of the steps necessary to complete a digital transaction. The three mechanisms, which have been investigated within the scope of different research projects, comprise of (1) graphical visualizations of service providers’ privacy policies and user-friendly management and matching of users’ privacy preferences “on the fly”, (2) methods for helping users create appropriate mental models of the data minimization property of anonymous credentials, and (3) employing touch-screen biometrics as a method to authenticate users into mobile devices and verify their identities during a digital transaction.   Results from these investigations suggest that these mechanisms can make digital transactions privacy-friendly and secure while at the same time delivering convenience and usability for ordinary users.

Developing Selective Lures to Optimize Striped Cucumber Beetle (<i>Acalymma vittatum</i>) Management by Combining Pheromone and Plant Volatiles

Rachel A Youngblood (18432096), Ian Kaplan (10232781), Donald C. Weber (3178635), Matthew Ginzel (8771376) 30 April 2024 (has links)
<p dir="ltr">The striped cucumber beetle (<i>Acalymma vittatum</i>) is a leading pest across a variety of cucurbit crops in eastern North America. These beetles can rapidly infest and damage a field, leading to frequent insecticide applications to manage them. Chemical control is effective at reducing beetle populations, but it also causes detrimental non-target effects on pollinators, which are essential for cucurbit yield. Developing a holistic IPM (integrated pest management) approach is necessary to manage pests while avoiding non-target effects in cucurbit production systems. </p><p dir="ltr">A unique and well-characterized behavior of striped cucumber beetles is their olfactory attraction to both plant volatiles and their species-specific aggregation pheromone, vittatalactone. The interacting effects of combining these olfactory stimuli for cucumber beetle attraction have not previously been tested. I expected when presented with plant volatiles and pheromone together, the striped cucumber beetles will show synergistic attraction, resulting in enhanced attraction stronger than the sums of the separate effects. Along with targeting striped cucumber beetles, I expected to elicit cross-attraction of related cucurbit pests (e.g., spotted cucumber beetle) to these same signals based on previous findings indicating cross-attraction. The expected cross attraction may be due to the reliance on olfactory cues to inform the related insects on preferrable host plants and nutrition. </p><p dir="ltr">Cucurbit systems are also highly reliant on pollination services for high-quality fruit; thus, the feasibility of these semiochemical tools depends on their influence on pollinator behavior. I expect pollinators to be attracted to floral volatiles but not vittatalactone or individual plant volatiles without the full complement of floral scent (e.g., indole, leaf volatiles). Altogether, this research aims to develop a targeted management tool for striped cucumber beetles and other cucurbit pests, while avoiding pollinator distraction or other detrimental effects.</p><p dir="ltr">To measure the efficacy of using olfactory signals as attractants, clear sticky cards were deployed in the field with combinations of pheromone paired with volatiles (floral and/or leaf), as well as the individual components, to quantify pest responses. Simultaneously, a pan trap sampling method was implemented to measure pollinator responses to the same semiochemical combinations. The results of the study demonstrate that striped cucumber beetles are strongly attracted to volatile lures containing pheromones, floral volatiles, and combinations of the two, although the combined pheromone and floral volatile treatments did not synergize beetle attraction. </p><p dir="ltr">Though combined lures did not synergize attraction, this data demonstrates additive effects on beetle behavior. The findings also highlight the importance of understanding seasonal disparities between the behavior of early and late generations of striped cucumber beetles. Temporal variation in attraction demonstrated by the pests is crucial to understand when to implement lure-based management strategies. Two years of testing floral volatile and herbivory-induced plant volatile (HIPV) lure treatments on key cucurbit pollinators showed varying levels of attraction. There was no attraction of focal cucurbit bees to the striped cucumber beetle pheromone, but there were differences in the response of pollinators to plant volatile components. </p><p dir="ltr">Cucurbits require high pollination activity for successful fruit, though the most important bees in pollinating this system are bees belonging to the genera, <i>Apis</i> and <i>Eucera</i>. Along with these bee groups, other bees such as those belonging to <i>Melissodes</i>, <i>Lasioglossum</i>, and <i>Bombus</i> are also known important pollinators. <i>Lasioglossum</i> bees showed a strong attraction to the full-floral blend, TIC (1,2,4-trimethoxybenzene, indole, (E)-cinnamaldehyde), but no preference for indole or HIPVs. <i>Melissodes</i> bees were most attracted to methyl salicylate and TIC, whereas <i>Eucera</i> bees exhibited strong attraction to ocimene and TIC. These findings suggest that different pollinator taxa have unique preferences for plant volatiles, highlighting the importance of optimizing lure combinations to avoid disrupting pollination activities in cucurbit production.</p><p dir="ltr">Additionally, this study revealed that other key cucurbit pests, such as spotted cucumber beetles and western corn rootworms, also showed strong attraction to the tested volatile components. These findings suggest that the selected volatiles may have broader implications for pest management beyond striped cucumber beetles. Further research is needed to fully understand the efficacy and refine formulations of these volatile lures to implement in IPM.</p>

The role of knowledge management in enhancing organisational performance in selected banks in South Africa

Chigada, Joel 09 1900 (has links)
Knowledge management (KM) has been cited as a strategic asset and a source of competitive advantage for organisations. While the issues of KM have been widely discussed by many researchers, there is a paucity of studies pertaining to the role of KM in enhancing organisational performance, especially in the banking sector. The focus of this research was to investigate the role of KM in enhancing organisational performance in selected banks of South Africa. The objective was to find out how knowledge was identified, captured, organised and retained in order to enhance performance of the banks. There is uncertainty about whether the use of KM could partly solve the banks‟ approaches to improving their quality of service to their communities in the modern information environment. Though KM has been implemented in commercial and business environments towards operational advantages and financial gains, KM survival principles and tools might help South African banks improve performance and fulfil their mandate. Knowledge, when properly managed, can significantly enhance an organisation‟s performance. The research design that was used in this study was an embedded case study design. Quantitative data were collected from a sample of middle level managers with the aid of a survey whilst interviews and document analysis were used to collect qualitative data. The findings of this study indicated that KM concepts were not universally understood at selected banks. The findings showed that collaboration between banks and the communities in creating a meaningful and relevant knowledge environment was essential for the survival of organisations. The banking industry practices were not deliberately based on KM but the study established that they were amenable to KM practices. The recommendation was to perform a knowledge inventory which could help develop appropriate institution-wide policies and practices for proper and well-organised methods of integrating work processes, collaborating and sharing (including the efficient use of knowledge technology platforms), and developing an enabling institutional culture. / Information Science / D.

How should the protection of privacy, threatened by new technologies like radio frequency identification (RFID), be seen from a Judeo-Christian perspective?

Schmidt, Erwin Walter 11 1900 (has links)
Radio Frequency Identification (RFID) is a new technology which allows people to identify objects automatically but there is a suspicion that, if people are tracked, their privacy may be infringed. This raises questions about how far this technology is acceptable and how privacy should be protected. It is also initiated a discussion involving a wide range of technical, philosophical, political, social, cultural, and economical aspects. There is also a need to consider the ethical and theological perspectives. This dissertation takes all its relevant directions from a Judeo-Christian theological perspective. On one side the use of technology is considered, and on the other side the value of privacy, its infringements and protection are investigated. According to Jewish and Christian understanding human dignity has to be respected including the right to privacy. As a consequence of this RFID may only used for applications that do not infringe this right. This conclusion, however, is not limited to RFID; it will be relevant for other, future surveillance technologies as well. / Philosophy & Systematic Theology / M. Th. (Theological ethics)
