A Critical Evaluation Of Traditional African Family System And Contemporary Social Welfare

Beyond reasonable doubt, the influence of Western culture and civilizations has enervated traditional African family systems, and their functions as providers of social welfare. Hitherto, traditional African family and clan by extension served as the plausible medium by which Africans proffered solutions to those social, economic and other existential problems found within their communities. However, measuring and evaluating the successes of the various social welfare programs organized by the family and clan was a difficult task to achieve. It seems the services rendered merely controlled the social problems but did not improve the standard of living of the victims. This paper seeks to critically analyse the traditional African family system and its role as a provider of social welfare and argues that it can complement the Western models towards holistic social integration. Thus this work adopts the theory of change as a tool for understanding how Western models of social welfare should be integrated with traditional African approaches to care for the ‘weak’ in the society. Advocating for a paradigm shift from the modern models of providing social welfare to the traditional African family and clan model is consequent upon the claim that the latter is more embracing in approach

Solving Higher Order Dynamic Equations on Time Scales as First Order Systems

Time scales calculus seeks to unite two disparate worlds: that of differential, Newtonian calculus and the difference calculus. As such, in place of differential and difference equations, time scales calculus uses dynamic equations. Many theoretical results have been developed concerning solutions of dynamic equations. However, little work has been done in the arena of developing numerical methods for approximating these solutions. This thesis work takes a first step in obtaining numerical solutions of dynamic equations|a protocol for writing higher-order dynamic equations as systems of first-order equations. This process proves necessary in obtaining numerical solutions of differential equations since the Runge-Kutta method, the generally accepted, all-purpose method for solving initial value problems, requires that DEs first be written as first-order systems. Our results indicate that whether higher-order dynamic equations can be written as equivalent first-order systems depends on which combinations of which dynamic derivatives are present

Blood Transfusion Errors within a Health System: A Review of Root Cause Analyses

IntroductionBlood transfusions are lifesaving treatments which require critical attention to processes and details. If processes are not followed, grievous errors can lead to sentinel events. A review of investigations completed due to reported events will show the error trends associated with systems used throughout the blood transfusion process. MethodsThis study employed root cause analyses (RCAs) within the Veterans Health Administration (VHA) to review the events leading to blood transfusion errors. Data was pulled from the RCA databases within the VA National Center for Patient Safety. The time frame was October 2014 to August 2019. A total of 53 RCAs and aggregated reviews were included in the study. These were reviewed for common themes and gaps present within processes. ResultsThe most common events fell within the categories of incorrect or delayed blood orders, incorrect or lack of patient identification, and wrong blood given. The RCA for each event was reviewed and studied. The RCAs had a crossover of multiple causes; lack of a formal process, communication barriers, and technology barriers were the most frequent. ConclusionThese RCAs express great variation between VHA facilities, such as process created, number of staff reports, and number of RCAs completed. Lack of standard practices nationwide, training barriers, and technology barriers may explain the variation of transfusion errors throughout the VHA. This study brings to light questions about standardization of transfusion protocols. Future study regarding such standardization is necessary to determine its plausibility

How the Structure of Choices Influences Consumer Decisions and Experiences

This dissertation contains three papers that together demonstrate how the structure of a choice process and of the information consumers encounter can influence what they think, feel, and do. Chapter 1 investigates how the structure of a choice process—and in particular, the timing of a decision to act relative to the timing of the action—influences how individuals feel at the point of acting. We demonstrate that the emotional experience of guilt is composed of two dissociable sources: one tied to the decision to act, and one tied to the behavior itself. With this unpacking, we find that introducing a temporal gap between one’s decision to act and one’s behavior allows decision guilt to decay, which reduces the guilt at the point of acting and carries important behavioral consequences.Chapter 2 probes the structure of a purchasing interaction. We compare two ways that the purchase and quantity decisions in a purchase process can be organized. In one, customers make the purchase and quantity decisions separately; in the other, customers simultaneously indicate whether and how much to buy. We find that the simultaneous consideration of both choices changes the psychology of how people decide, and ultimately increases their willingness to purchase. In 27 lab experiments and a large field experiment, we find that this “quantity integration” can lead to substantial lift.Finally, chapter 3 reveals how the structure of one aspect of a customer interaction, a small monetary incentive, can influence what people believe and accordingly what they do. We show that customers who encounter a small surcharge for failing to perform some behavior infer that this behavior is more socially normative than those who encounter a small discount for performing it. This inference carries key consequences, changing how people feel and what they decide to do in the future. Collectively, these three chapters demonstrate the critical importance of the structuring of choices and information for consumers’ beliefs, emotional responses, decisions, and behaviors

The Racial Attitudes of the White Person Toward the Black Person as Represented in Selected Works of James Baldwin

This study concerns itself primarily with James Baldwin's treatment of the attitudes he thinks most white people hold. He desires to make the white man conscious of his attitude towards Negroes and to analyze the reasons for them, and incorporates his ideas into setting, characterization, and plot

An ergonomics intervention study into the physiological, perceptual and productivity effects of three citrus harvesting bag designs in the Eastern Cape of South Africa : a combined laboratory and field approach

Background: Agriculture plays a vital role in the economy of any industrially developing country, including South Africa. In the Eastern Cape of South Africa citrus farming is a significant contributor to the local economy (Johnson et al., 2005). The harvesting phase of citrus farming is performed manually and exposes workers to physical risks, which can lead to the development of musculoskeletal disorders. In particular, the standard harvesting bag comprises of a single shoulder strap and promotes asymmetrical load carriage which results in shoulder and lower back pain complaints. The current study compared the physiological (EMG), perceptual (RPE), usability (PUEU) and productivity effects of two new harvesting bag designs (a hip belt and a backpack bag design) to the standard harvesting bag design. This was performed in a laboratory as well as a field setting. Methods (Laboratory phase): 36 participants (12 males and 24 females) were assigned to one worker group. The “tall ladder worker” group was comprised of only males and the “step ladder worker” and “ground worker” group of females. Each participant was required to simulate a citrus harvesting task while utilizing each of the bag designs on different days. On each day/test session, participants performed three harvesting cycles. Muscle activity was measured throughout the entire testing session and RPE were recorded at the end of each cycle. Results (Laboratory phase): The EMG and RPE results indicate that the backpack design was the most ideal design to reduce asymmetry, while the standard harvesting bag design was the worst. Although not significant, there was greater muscle asymmetry (p=0.109) and a significantly higher perceived exertion when using the standard bag (p=0.0004), in comparison to using the backpack. Methods (Field phase): 17 Xhosa-speaking citrus harvesters (6 females and 11 males) participated in this study. Each harvester worked with one of the three bag designs on a different day. Productivity of each worker was assessed every hour by recording the number of bags filled with fruit and at the end of the shift. A Perceived Usefulness & Ease of Use questionnaire was presented to each participant to obtain feedback on worker acceptance to the new bag designs. Results (Field phase): A general trend in support of the hip belt bag design over the other two bag designs were found, even within the different worker demographic groups (age, sex and worker experience). The workers perceived less exertion (7.98 ± 1.86) and were more productive (9.90 ± 2.11 bags/hour) when using the hip belt design; they also found this bag the most useful (1.02 ± 0.09) and easy to use (1.07 ± 0.25). In contrast, the backpack bag design had significantly poorer responses when compared to the other two bag designs and this was evident in all the dependent variables assessed (RPE, productivity and PUEU). Conclusion: The results from the laboratory phase supported the expectation that the backpack bag design reduces asymmetry and hence, is more suitable than the standard harvesting bag. However, results from the field show that the hip belt bag design was the most preferred and the backpack was the least preferred. Bao & Shahnavaz (1989) highlight the need for ergonomics researcher to convey laboratory findings into the field context. However, as shown by the current study, there are numerous challenges associated with field work, making it difficult for laboratory findings to be successfully conveyed to the field. Limitations and Recommendations: For the laboratory phase of the project, no biomechanical and cardiovascular responses were assessed. However, for a holistic approach, these variables should be considered in future studies. Due to high variability from one harvesting cycle to another, more than three harvesting cycles should also be performed to accurately replicate the harvesting process as done in the field over extended durations of time. For the field phase, data should be collected from more than one citrus farm and thus a larger sample size could be obtained. This would improve the validity of the study. In addition to this, data should be collected for a full working day, especially if environmental conditions are not a hindrance, as well as for a whole season, since workloads vary, depending on the time of the harvesting season.Name on Graduation Programme: Bassey-Duke, Elizabeth Missa
