Price setting in the South African coffin industry.

02 October 2007 (has links)
The aim of this study is to analyze the price setting in the South African coffin industry which is affected by the HIV/AIDS pandemic. Consumer behavior and decision making, producer and retailer response, as well as the overall effects that this industry may have within the realm of the South African economy is analyzed. The central focus however, is the price determination governing the supply and demand relationship, and the influence that this relationship has on the market mechanism, which is important in regulating the functioning of the South Africa coffin industry. Chapter One introduces the problem statement by highlighting the purpose of the study in light of the effects of HIV/AIDS. The link between the coffin industry and the economy is the increase in mortality rates caused by HIV/AIDS. Sub-Sahara is the worst affected global region, and within South Africa over four million people have been affected by the pandemic. The effects on the economy can be observed on several fronts for example, the weakening of South Africa’s social structure, increasing costs to the state by putting pressure on the limited medical facilities and other social institutions, reducing the skill base, reducing national economic growth rates, etc. Due to the high levels of unemployment experienced in South Africa, several problems become relevant, especially in rural areas. Such problems can be highlighted in terms of an increase in the financial burden placed on those paying for burials. This is also extended to those organizations supplying financial aid to help cover the costs, such as societies and funeral policies. Due to the low levels of income experienced by many in urban centers, this puts a great deal of pressure on government to assist in the burial of those whom are not in a position to afford the funeral costs. Due to the upward pressure on demand for coffins, prices for coffins may increase, which will be transferred onto the rural population, which characteristically experience a greater degree of low incomes, putting additional financial pressure on these people. The increased rate of burials increase the demand on limited burial space, causing costs to rise, putting additional pressure on household savings. This becomes increasingly important, as the levels of household savings in South Africa are relatively low. Chapter Two focuses on the theoretical aspects of price determination. Price setting behavior is not only a method of profit maximization, but is also an extension of marketing strategies used to generate and establish a larger share of any target market. This chapter is based on a literary survey and applies a theoretical approach to price determination, analyzing and comparing market structures. Pricing strategies, nominal and real price rigidities and modern pricing methodologies under the influence of Internet and global markets are explored. Chapter Three takes a close anthropological review of traditional South African cultures and religions, and illustrates how these traditional beliefs and religions influence the decision making of the consumer and the undertaker. Within the context of these cultural perspectives, the issue of cremation as an alternative to the burial is explored. An analysis of the consumer demand is achieved by using the data collected for the consumer and the undertaker surveys. The costs and the consumer decision making regarding burial practices and the financing thereof is highlighted. Burial policies and funeral societies are discussed, and the overall effect that they have on consumer spending patterns, the misallocation of resources as well as the negative tradeoff effects of this misallocation has on the employer, the household, the government and the overall economy. The financing of funerals is also an important issue as the high rates of unemployment and the huge social demands that it places on consumers are forcing the majority to search for funding from other sectors of the economy that already feels the strain of a global slowdown. Economically, this chapter challenges the traditional customs and the redirection of scarce resources that are been greatly misallocated into inappropriate sectors. Chapter Four investigates the influence of HIV/AIDS on the economy, and the influence that HIV/AIDS has on the South African coffin industry. This chapter highlights the spread of the HIV/AIDS virus and the influence that this virus has on society. The role woman play in the South African economy, and the effect of HIV/AIDS on the labor force. The discussion then focuses on HIV/AIDS and the workings of the coffin industry and the near perfectly competitive market structure that functions within the South African coffin industry. Pricing strategies highlighting the role of religion, HIV/AIDS and income are considered and the role of the undertaker in society. The research was predominantly based on the information generated in the undertaker and the consumer surveys as well as a literary survey. However, the undertaker does not operate independently. There are many related industries, which are discussed, and the relationship between them is highlighted. The growth of the complementary industries, similarly, must not be underestimated, as the coffin industry provides them with a springboard from which they may enter the market. Chapter Five constructs a model to show how the influence of HIV/AIDS affects the price setting behavior of coffins. Thereafter, the model introduces the concept of competition, showing how the growing rate of competition, in conjunction with HIV/AIDS, is a more suitable model in determining the influence on price setting behavior. The model is based on the Ordinary Leased Squared (OLS) method, and the model is tested on economic a priori, Statistical evaluation and econometric tests, for example, Autocorrelation, Heteroscedasticity and Multicollinearity. Using Theils Inequality Coefficient, the model is proven sound for forecasting purposes. The combination of HIV/AIDS and competition using the SIC and AIC test proves that this combination is a better-forecast model than if HIV/AIDS was used as a determinant on its own. In chapter Six, the construction, distribution and analysis of the Consumer and the Undertaker surveys are discussed. For the purpose of the study, it became obvious that within the South African coffin industry, there is a gap between available literature on the industry and what was required for the compellation of this research. A detailed discussion on the methodology, purpose, the target sample, limitations and format of the surveys is discussed. The data collected proved very useful on two fronts: Firstly it provided detailed information that was required in order to complete the study. Secondly, the data collected introduced new questions and opened new doors to further investigation. The data provided sufficient information to show the relationship between the economy and the coffin industry. In chapter Seven, the main findings of the study are highlighted by the overwhelming influence of HIV/AIDS which has affected both the nature of the market, as well as price setting behavior. However, it has led to a large degree to the misallocation of resources, that are required in other spheres of the economy. The motivation behind funeral policies is an area of concern, and requires additional research into the social and economic influence of such structures. The influence of the rapid growth of competition has a large role to play in the coffin industry. Furthermore, the traditional beliefs of the consumer need to be protected and the role of the undertaker in this regard is a major concern. The final chapter highlights areas of further research, makes note of shortcomings in the available literature and highlights the role of policy makers with respect to the South African coffin industry.

Fatigue Lifes of Sn/Pb and Sn/Ag/Cu Solder Balls

Wu, Cheng-Hua 24 July 2004 (has links)
The Coffin-Manson equations of Sn/Ag/Cu and Sn/Pb solder joints are presented in this thesis. The experimental results of CSP thermal cycle fatigue test and ball shear test are used to formulate Coffin-Manson equations. The maximum amplitude of equivalent plastic shear strain corresponding to these two experiments are employed. The MARC finite element package is used to calculate the plastic shear strain. Different published fatigue experiment results have been used to show the accuracy and the feasibility of these proposed equations. The 3-D finite element models of the BGA type¡¦s CSP and VCSEL assembly are employed to simulate the thermal cycling fatigue. Results indicate that the fatigue lifes of solder predicted by using the proposed equations have good agreement with those measured from experimental tests.

Unraveling molecular, cellular and cognitive defects in the mouse model for mental retardation caused by Rsk2 gene mutation / Identification des déficits moléculaires, cellulaires et cognitifs chez le modèle souris du retard mental causé par la mutation du gène Rsk2

Mehmood, Tahir 24 February 2012 (has links)
Le syndrome de Coffin-Lowry (CLS), une déficience intellectuelle liée à l'X, est causée par des mutations du gène RPS6KA3 codant pour la kinase RSK2 régulée par les facteurs de croissance.Pour comprendre les conséquences du déficit en RSK2 dans l'hippocampe nous avons effectué une comparaison des profils d'expression génique d'hippocampes de souris Rsk2-KO et WT. Elle a révélé l'expression différentielle de 100 gènes, codant pour des protéines agissant dans divers processus biologiques. Nous avons analysé les conséquences de la dérégulation de l'un de ces gènes Gria2 codant pour GluR2, une sous-unité du récepteur glutamate AMPA. Un niveau d'expression doublé de GluR2 a été relevé dans l'hippocampe des souris Rsk2-KO et les études électrophysiologiques y ont révélé une réduction des transmissions AMPAR et NMDAR. L’activité de ERK1/2 était aussi anormalement augmentée dans l'hippocampe des souris Rsk2-KO, ainsi que le niveau de P-Sp1. Ensemble, mes résultats ont suggéré que la surexpression de GluR2 dans les neurones déficients en RSK2, était causée par une augmentation de l'activité transcriptionnelle de Sp1 sur le gène Gria2, qui, elle-même, est le résultat de l’augmentation anormale de l’activité de ERK1 / 2. / Coffin–Lowry Syndrome (CLS), an X-linked form of intellectual disability, is caused by mutations of the RPS6KA3 gene encoding the growth factor regulated kinase RSK2. To understand the consequences of RSK2 deficiency in the hippocampus we performed a comparison of the hippocampal gene expression profiles from Rsk2-KO and WT mice. It revealed differential expression of 100 genes, encoding proteins acting in various biological pathways. We further analyzed the consequences of deregulation of one of these genes, Gria2 encoding GluR2, a subunit of the glutamate AMPAR. An abnormal two-fold increased expression of GluR2 was found in the hippocampus of Rsk2-KO mice. Electrophysiology studies showed a reduction of basal AMPAR and NMDAR mediated transmission, in the hippocampus of Rsk2-KO mice. Activity of ERK1/2 was also abnormally increased in the adult hippocampus of Rsk2-KO mice. P-Sp1 level was also significantly higher in RSK2 deficient cells. Together, my results suggested that over expression of GluR2 in RSK2 deficient cells, is caused by increased Sp1 transcriptional activity on the Gria2 gene, which, itself, is the result of ERK1/2 increased signaling.

[pt] AVALIAÇÃO DA PREVISÃO DE VIDA DE PEÇAS ENTALHADAS SOB CARGAS DE AMPLITUDE VARIÁVEL / [en] EVALUATION OF FATIGUE LIFE PREDICTION OF SPECIMEN WITH STRESS FACTOR CONCENTRATION UNDER VARIABLE AMPLITUDE LOADING

KALLIN DE SOUZA 30 April 2020 (has links)
[pt] O método EN baseia-se na quantificação do dano causado pela deformação decorrente do histórico de carregamento. O objetivo desse modelo consiste em estimar o número de ciclos para iniciar uma trinca por fadiga. Diferente do método SN o número de variáveis envolvidas nesse modelo é menor. Entretanto, requer um número maior de constantes, que nem sempre podem ser obtidas experimentalmente. Esse fato levou a formulação de diversos modelos que se propõem a estimar as constantes de Coffin-Manson, que na maioria dos casos levam a previsões de vida não conservativas, como visto em outros trabalhos. Contudo a maioria dos casos existentes na literatura não abordam o efeito de regiões de concentração de tensão e a influência de carregamentos com amplitudes variáveis. A metodologia usada nessas pesquisas consiste em avaliar a influência desses aspectos através da comparação entre a vida em fadiga experimental e a estimada segundo as constantes de Coffin-Manson medidas e estimadas segundo diferentes modelos. Esse estudo avalia o dano à fadiga segundo 2 tipos de concentradores de tensão e quatro históricos de carregamentos de amplitude variável. Considerando os modelos de Manson, Muralindhran-Manson, Bäumel-Seeger and Meggiolaro-Castro os resultados mostram que a vida em fadiga prevista usando os parâmetros de Coffin Manson obtidos segundo o método de Meggiolado-Castro e por Baumel-Segger são os que mais se aproximam das vidas estimadas baseada nas constantes experimentais. Nos demais casos nota-se que a regra de concentração de tensão exerce uma maior influência no resultado e levam a vidas à fadiga não conservativas. / [en] The strain-life designed is based on the damaged caused by the strain as a result of a loading history. The purpose of this approach is estimating the number of cycles to initiate a fatigue crack. Compared with the stress life method the EN needs a lower number of variables. However, it needs a large number of parameters that are not directly measurable properties of a material and conduct the necessary number of tests to obtain them is not always an option. This fact leads to the formulation of different models to estimate Coffin- Manson s constants, which in most of the cases can result in a non-conservative fatigue life prediction, as seen in several papers. However, in these studies, it is not considered a specimen with a stress concentration factor neither under a variable amplitude loading history. The methodology used in this research is evaluating the influence of these aspects by comparing the fatigue life experimental with the estimated by using the Coffin Manson s experimental constants and the fatigue life calculated with different models to estimate the Coffin-Manson s parameters. This study evaluated the fatigue damage based on four load histories and two types of samples with different stress risers. Considering the models of Manson, Muralidharan-Manson, Bäumel-Seeger, and Meggiolaro-Castro the results indicated that the fatigue life predicted using the Coffin Manson s parameter obtained by Meggiolaro-Castro and Baumel-Segger s model are more similar to the life calculated with the experimental constants. The other models are more influenced by the stress concentration s rule and can lead to not conservative fatigue life.
