ABSTRACT: This study was carried out to ascertain the perception of students on the use of social media for educational purposes. It was conducted in three tertiary institutions in Rivers State. The sample comprised 200 respondents randomly selected from three tertiary institutions in Rivers State. Five research objectives and four null hypotheses were used for the study. Mean scores, ANOVA, multiple comparison test using schaffer model, and Correlational Analysis were the statistical tools used in the study. The study found that social media is used in the study. The study found that social is used for educational purposes in terms of communication, sharing and exchanging ideas with improved engagement with technology..

ABSTRACT: As a result of continuous economic growth, urbanization and industrialization there has been increase in volume and types of solid and hazardous waste particularly in developing countries. Many Nigeria cities and towns are facing problems of effective collection of garbage from homes and streets the situation that make Nigerians to be permanently accustomed to dirt environment. Based on this background, the paper examines the waste conditions and disposal as well as the influence on the environment in term of cleanliness at Ado Ekiti in Nigeria using both primary and secondary sources of data collection which were subjected to descriptive statistical analysis.

ABSTRACT: Mobile Cloud Computing (MCC) is an infrastructure where the data and the processing of data are outsourced. MCC integrates cloud computing into the mobile environment and executes the applications in the mobile device effectively by partitioning and offloading the computation intensive task to external resources (e.g. Public Clouds). The effective offloading is mainly focused on the decision maker which tells "when to offload" during execution time. Though prior decision making techniques has its own pros and cons, it doesn't support dynamic changing environment and also consumes more time and energy for training the input instances. Also while offloading there is no security for the information to be transmitted.
