Understanding Facebook Continuance Intention – A Path Analysis Approach

For over a decade, Facebook is part of the everyday life of university students. Its growing popularity is stimulating researchers to understand the factors that are driving young people to join and use social networking websites. The technology acceptance model is a well-known theory that has been widely used to explain technology acceptance and the intention to further use it. This paper aims to analyze in more detail the continuance intention by taking into account four facets of Facebook's usefulness. A path analysis approach has been taken in order to analyze the contribution of six factors: perceived enjoyment, usefulness for career orientation, usefulness for personal development, usefulness for finding information and resources, usefulness for socialization and collaboration, and perceived ease of use. The results show that the perceived enjoyment is the main driver of the continuance intention, followed by the perceived ease of use, usefulness for career orientation, and usefulness for collaboration and socialization.

An Integer Programming Solution to the Riddle of the Pilgrims

Henry E. Dudeney is one of the most prolific, talented and best-known math riddle developers of all time. His 1907 publication The Canterbury Puzzles and Other Curious Problems, still in publication, is a classic. One of the riddles titled “The Riddle of the Pilgrims” developed decades before the development of linear and integer programming is a very good example of the challenge of formulating an integer optimization problem. This paper illustrates both the formulation and solution the “Pilgrim’s Riddle” as an integer programming problem.

On the Distribution of Uganda Parliamentary Seats: An Interesting Application of Beta Distribution

The paper uses a combination of different statistical analysis to analyze the distribution of Members of Parliament across different ethnic groups in Uganda. The paper uses national population data obtained from Uganda National Bureau of Statistics (2016), data from Parliament of Uganda and some data from the global parliamentary report (2012). The overall results indicates that although some ethnic groups appear to be under/overrepresented relative to their population size, based on both expected value and international benchmark criteria, these absolute discrepancies appear not to be statistically significant based on estimation of beta distribution. Further robustness checks using the 2-3 standard deviation tests indicate that all the absolute discrepancies of the observed numbers of Members of Parliament whether above or below the expected number are not more than 3standards deviations. These results suggest that discrepancies noted are not significant. The paper concludes by suggesting some policy recommendations.
