The impact of real exchange rate volatility on economic growth: Kenyan evidence
Danson Musyoki,Ganesh P. Pokhariyal,Moses Pundo
Business and Economic Horizons , 2012,
Abstract: This paper examines the impact of real exchange rate volatility on economic growth in Kenyan. The study employed the Generalized Autoregressive Condition of Heteroscedasticity (GARCH) and computation of the unconditional standard deviation of the changes to measure volatility and Generalized Method Moments (GMM) to assess the impact of the real exchange rate volatility on economic growth for the period January 1993 to December 2009. Data for the study was collected from Kenya National Bureau of Statistics, Central Bank of Kenya and International Monetary Fund Data Base by taking monthly frequency. The study found that RER was very volatility for the entire study period. Kenya’s RER generally exhibited a appreciating and volatility trend, implying that in general, the country’s international competitiveness deteriorated over the study period. The RER Volatility reflected a negative impact on economic growth of Kenya.

International Journal of Business and Management , 2012, DOI: 10.5539/ijbm.v7n16p118
Abstract: The purpose of this study was to investigate the key reasons behind the decision by the firm management of Nairobi Securities Exchange (NSE) listed firms to cross-list in East African Exchanges. The study employed a descriptive research design. A Likert type questionnaire was administered to the Chief Executive Officers (CEOs) or the Chief Financial Officers (CFOs) of the target firms. The study conducted factor analysis to identify the key reasons for the cross-listing in the East African region. The key reasons identified were investor recognition, expansion of business, boosting of sales and desire to lower the cost of capital. The factor analysis did not provide evidence that legal bonding is a motivation for the cross-listing by NSE firms. The findings from the study appear to indicate that there may exist contextual differences in the decisions to cross-list, consequently generalizations may not suffice.

Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102850
Abstract:
The aim of this study was to establish the factors influencing improvement in performance and delivery of public services. Thus, the paper studied the effect of performance contracting and measurement on public service delivery in Kenya. The public services considered in the study included ministries, state corporations, local authorities and tertiary institutions, with a total of 470 public agencies. The cross-sectional survey design was used. The study is based on performance evaluation results compiled over the period between 2004 and 2011. Using regression analysis, it was found that performance measurement was critical to improvement in public service delivery and explained 73.6 percent of improvement in service delivery, as evidenced by independent measurement of customer satisfaction with the services delivered by the public sector.
A Study of the Intervening Effect of Political Stability on the Relationship between Performance Contracting and Measurement, and Public Service Delivery in Kenya  [PDF]

Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103402
Abstract:
The performance of public agencies is influenced and affected by many factors, both internal and external. The internal factors are in many cases controllable, while external factors tend to fall outside the control of public sector managers. Moreover, the effect may serve to ameliorate performance or intervene to weaken performance and thereby adversely affect delivery of services. This paper explored the intervening effect of political stability, an external factor, on the relationship between performance contracting and measurement, and public service delivery (expressed as customer satisfaction) in Kenya. The study was based on the results of measurement and evaluation of the performance of 470 public agencies that operated under performance contracts between 2004 and 2011. Using regression analysis, it was found initially that on its own, political stability had no significant relationship with or influence on customer satisfaction. It however had an effect on the relationship between performance contracting, measurement and public service delivery, where a unit change in political stability contributed negatively to customer satisfaction by a factor of 0.257, though not statistically significant. Correlation analysis established further that social chaos and turmoil, which result in political instability, negatively impact the attractiveness of a country in the global arena.
A Study of the Joint Effect of Performance Measurement, Political Stability and Global Competitiveness on Customer Satisfaction  [PDF]

Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104917
Abstract:
The performance of governments in the delivery of services to the pub-lic—which constitutes the customers who are the tax payers, is affected and influenced by a multitude of factors, some controllable and others outside the control of governments. In addition, each of the diverse factors impacts uniquely on performance while others may have only tangential influence. According to Hansen (1989), there are two streams of research regarding the determinants of firm performance. One is based on the economic tradition and emphasizes external market factors that are largely outside the control of firm management, while the other builds on the behavioral and sociological paradigms focusing on organizational factors as they fit into the environment; the latter therefore focuses on factors internal to the firm. A combination of various factors working together however, has the potential to generate a blend of influences, which is a significant departure from the impact of any factor taken on its own. The ensuing study is set out to establish the joint effect of performance measurement, political stability and global competitiveness—critical internal and external factors that affect or influence the performance of governments—on public service delivery and its customer satisfaction derivative in Kenya. The study was based on the results of measurement and evaluation of the performance of 470 public agencies that operated on performance contracts between 2004 and 2011. Using regression analysis, it was found initially that each of the three factors had a uniquely significant effect on the relationship between public service delivery and customer satisfaction, with performance measurement showing a strong positive relationship (R = 0.858) with customer satisfaction. Performance measurement explained 73.6 percent (R2 = 0.736) of customer satisfaction levels with the remaining 26.4 percent accounted for by other factors. Global competitiveness on the other hand, had a weak positive relationship with customer satisfaction. The results showed that global competitiveness explained 0.7 percent (ΔR2 = 0.007) on the direct effect of performance measurement on customer satisfaction and had an average mean of 3.698 on a scale of 1 (very low) and 5 (very competitive). It turned out that there was no significant moderating effect of global competitiveness on the relationship between performance contracting, measurement and public service delivery in Kenya. The performance measurement variable had a t-value of 5.789 and was statistically significant while the effect of global competitiveness was positive although not statistically significant. Preliminary findings established initially that on its own, political stability had no significant relationship with or influence on customer satisfaction. It however had an effect on the relationship between performance contracting, measurement and public service delivery, where a unit change in political stability contributed negatively to customer satisfaction by a factor of 0.235, though not statistically significant. Correlation analysis established further that social chaos and turmoil, which result in political instability, negatively influenced the attractiveness of a country in the global arena. Overall, the results showed that performance measurement, political stability and global competitiveness were positively related to customer satisfaction. The joint effect of the three independent variables explained 78.5 percent (R2 = 0.785) of customer satisfaction levels with the remaining 21.5 percent accounted for by other factors implemented in the public sector.

BMC Research Notes , 2012, DOI: 10.1186/1756-0500-5-559
Abstract: The average length of illness was 2.43 years (SD ± 3.0). Only 7.5 %( n=15) reported to having used the internet as a source of information. 92.5 %( n=184) did not use internet. With Multiple options, 70.9% did not know how to use a computer, 29.2% did not have access to a computer, 14.6% lacked the money to use computers at the local cyber cafe while other barriers identified accounted for 11.1%. Patients reported that the internet had an important role in the management of cancer of the cervix in health education (17.6%), online consultation (14.6%), booking of patients (13.6%), referrals (8.5%) and collecting data (7%). The 96.5% of the respondents who had access to a mobile phone, recommended mobile phones for health education messages (31.7%), reminder alerts for medication (29.7%) and booking appointments (21.6%). There was a statistically significant association between income of the patients and internet use (p = 0.026) in this study.There is low level use of the internet by cervical cancer clients attended in Public referral facilities in Kenya. This was attributed to; lack of knowledge on how to use computers and lack of access to a computer. High level of access to mobile phones was reported. This is an indicator of great potential for use of mobile phones in the management of cervical cancer through short messaging services (sms), without internet connectivity. There is even greater potential to internet use through web access via mobile phones.Worldwide, Cervical cancer causes approximately 46,000 deaths each year in women aged 15–49 years and is estimated to account for 15% of all female cancers in developing countries [1]. In Kenya, cervical cancer continues to be a major health concern. Estimates indicate that every year 2635 women are diagnosed with cervical cancer and 2111 die from the disease [2]. It is also projected that in 2025, there will be 4074 new cases of cervical cancer in Kenya and that 3293 deaths will be as a result of cervical cancer [

International Journal of Morphology , 2011,
Abstract: The variations in morphometric parameter of mammalian brains may be influenced by process of functional complexity, evolution and adaptation. Comparative analysis of linear measurements of cerebrum in the human and baboon has shown morphometric differences. In the present study linear measurements from human and baboon cerebrum (n=10 each) were used to predict various values for human and baboon brain and body parameters through multiple regression models. The average brain weights were found to be 2.08% and 0.84% of the body weights for humans and baboons respectively. The elasticity of regression models revealed that unit percentage increase in Occipital-Frontal (OF) distance would increase the human brain weight by 66.19%, while the baboon brain weight would increase by 7.63%. The unit percentage increase in the Height of Temporal Lobe (HTL) would increase the human brain weight by 16.28%, while the baboon brain weight would increase by only 0.28%. Unit percentage increase in Frontal-Temporal (FT) distance would decrease the human and baboon brain weights by 14.04% and 0.46% respectively. Inter-species values were also predicted through simulation techniques by using the ratios of model parameters with application of programming language Python. The OF, FT and HTL values for human were found to be 2.01 times, 1.55 times and 1.91 times respectively to that of baboon. Las variaciones en los parámetros morfométricos del cerebro de los mamíferos pueden estar influenciadas por el proceso de complejidad funcional de la evolución y adaptación. Análisis comparativo de las mediciones lineales del cerebro en el humano y babuino han puesto de manifiesto las diferencias morfométricas. En este estudio las mediciones lineales del cerebro humano y babuinos (n = 10 cada uno) fueron utilizados para predecir los valores distintivos para el cerebro de humanos y monos babuinos y los parámetros del cuerpo a través de modelos de regresión múltiple. El peso medio del cerebro resultó ser 2,08% y 0,84% del peso corporal de los seres humanos y los babuinos, respectivamente. La elasticidad de los modelos de regresión reveló que el aumento de una unidad porcentual en la distancia occipital-frontal (DE) aumentaría el peso del cerebro humano en 66,19%, mientras que el peso del cerebro babuino se incrementaría en 7,63%. El porcentaje de aumento en la altura de lóbulo temporal (HTL) aumentaría el peso del cerebro humano en 16,28%, mientras que el peso del cerebro babuino aumentaría en sólo el 0,28%. Si aumenta la distancia frontal-temporal (FT) se reduciría el peso del cerebro huma
Relativistic segnificance of curvature tensors

International Journal of Mathematics and Mathematical Sciences , 1982, DOI: 10.1155/s0161171282000131
Abstract: In thi paper new curvature tensors have been defined on the lines of Weyl's projective curvature tensor and it has been shown that the “distribution ” (order in which the vectors in question are arranged before being acted upon by the tensor in question) of vector field over the metric potentials and matter tensors plays an important role in shaping the various physical and geometrical properties of a tensor viz the formulation of gravitational waves, reduction of electromagnetic field to a purely electric field, vanishing of the contracted tensor in an Einstein Space and the cyclic property.
