This paper presents a queuing model to evaluate the latency associated with file transfers or replications in peer-to-peer (P2P) computer systems. The main contribution of this paper is a modelling framework for the peers that accounts for the file size distribution, the search time, load distribution at peers, and number of concurrent downloads allowed by a peer. We propose a queuing model that models the nodes or peers in such systems as M/G/1/K processor sharing queues. The model is extended to account for peers which alternate between online and offline states. The proposed queuing model for the peers is combined with a single class open queuing network for the routers interconnecting the peers to obtain the overall file transfer latency. We also show that in scenarios with multipart downloads from different peers, a rate proportional allocation strategy minimizes the download times.

The purpose of this study was to establish the extent to which CBOs in Kisumu County apply Ansoff's Product Market Growth Strategy. In this context the study examined the four Ansoff's growth Strategies namely: Market Penetration, Market Development, Product Development and Diversification Strategies. The study was descriptive in nature. The population of interest consisted of Community Based Organizations in Kisumu County which numbered 223 CBOs. Given the large number of CBOs, a sample size was targeted and random sampling conducted. Primary data was collected using a structured questionnaire administered to the respondents through drop and pick later method. Out of a targeted sample of 69 CBOs, 59 of them responded giving 85% response rate while data was analyzed using mean scores, standard deviation and t-tests. Findings showed that CBOs apply all the four growth strategies with market penetration being the most widely applied. The respondents stated relevance in services/products offering as the most influencing factor to their strategic choice while attracting donor funding remained the least. On views on how to improve on the capacities and growth of local CBOs, majority respondents expressed improved funding, improved community mobilization and improved method of service/products delivery as most applicable. Study findings present market penetration strategy as the most preferred through free added services. This is an indication of what heads of CBOs should pursue in order to achieve their organizational growth. Pursuit of Relevance in service offerings and competition are leading factors influencing choice of strategy. While the study served to fill a knowledge gap, it has well opened more areas like exploring levels of competition within CBOs by scholars. The fact that there is growth in CBOs should inform the Government and other nongovernmental organizations that CBOs have a role to play in achieving millennium goals. Thus, handling of CBOs operational limitations like lack secure and permanent facilities are crucial dimensions for their growth.

Alcohol abuse is a major global contributing factor to death, disease and injury. Alcohol abuse results in approximately 2.5 million deaths each year, with a net loss of 2.25 million lives, considering the estimated beneficial impact of low levels of alcohol use on some diseases in some population groups. The purpose of this study was to assess the influence of religious affiliations on alcohol abuse among public school teachers in Nyeri County. The study used both correlational design and phenomenological design. Quantitative and qualitative approaches were used in determining the relationship existing between religious affiliation and alcohol abuse and establishing the perception of teachers on alcohol abuse respectively. The study utilised the stratified sampling methodology to select participating teachers in each sub-county and level of the school (primary or secondary). The study had a sample size of 385 respondents. The ratio of primary school teachers to secondary school teachers in the overall teacher population was 5:3 which was also observed in the sample mainly attributed to the high number of primary schools as compared to secondary schools. A sampling frame was obtained from Teachers Service Commission (TSC) providing a list of all teachers in the county and the schools they teach in. The study utilized the stratified sampling methodology to select participants, where strata used was the subcounty and type of school (primary/secondary). A sample of 385 teachers was selected from a population of 6,264 from Nyeri County. A self-administered questionnaire was used to collect data. Data was coded and analysed using descriptive and inferential statistics. The religious affiliations and alcohol abuse had a weak correlation of .290). However, religious affiliation had no significant effect on alcohol abuse among the teachers at .096. The study concludes that there is a relationship between religious affiliation and alcohol abuse among school teachers in Nyeri County. The study recommends religious affiliations to be encouraged as a part of prevention strategies.

The contemporary Nigeria society has been a theatre of unending insurgency from the Fulani herdsmen. The spate of violent attacks from these insurgents against farmers in various part of the country has become a thing of great worry to all. This is moreso as the federal government appears unwilling to bring to book those behind the increasing deadly menace. This paper will therefore seek to examine the socio-ethical religious implications of the above insurgency with a view to charting the way forward. Relevant published texts across the country and the structural conflict theory provided the leverage for this study.

The present study is aimed to analyze the statistical relationship among various water quality parameters and water quality index (WQI). For this, observed results of physico-chemical analysis of 71 ground water samples of study area in pre- and post-monsoon season and calculated water quality index values for each respective sample were taken into consideration. Correlation coefficient between every water quality parameter and WQI values is calculated and for the pairs having highly significant correlation coefficient (0.8<r<1.0) values; regression model is applied and scatter plots are drawn. The systematic correlation and regression study suggested the perfect linear relationship between Fluoride and WQI Values. The analysis provides essential information regarding the dependency of water quality rating on each water quality parameter.

The study examines the challenges behind the succession and sustainability of family businesses. Mentoring was identified as the means to tackle this menace. The study was conducted in Ogbomoso, Nigeria. Eight family businesses were selected through purposive sampling method. The inclusion criteria were operational family businesses in their second or more generation. Data were collected using fifteen semi structured, in depth, face to face interviews with participants. Sampling continue until saturation of the data was reached. Content analysis approach was applied to analyse the data. Family business successors acknowledged mentoring shaped their emergence as the successor of their family businesses. 

In the global economy of the 21st century, international trade will be a key source of economic growth and development. Recent surveys conducted in several countries by the National Foundation of Women Business Owners (NFWBO) indicate that women-owned firms involved in the global marketplace have greater revenues, are more optimistic about their business prospects and are more focused on business expansion than women-owned firms that are domestically oriented. Obviously, expanding into international trade can pay off for women-owned firms. However, it is not clear that smaller enterprises are benefiting from these potential as much as larger firms. In connection with the above here an attempt has made to study the role of women entrepreneurs in economic development.
