Various technology adoption models have been proposed to explain the adoption of technologies in different settings, such as organizational and individual, as well as in the voluntary and mandatory contexts. Recently, uptake of mobile phones in achieving organisational targets has been increased in developing countries and Tanzania in particular. This is due to the notable improvements in both hardware performance and sophistications. In organisation context, not all users are willing to use technology as required. In such circumstances, they are mandated to use it in order to fulfil their working duties. This leads to poor uptake of technology and results to unclear understanding regarding to their attitudes towards using it. While some studies have discussed the impact of voluntariness in using traditional desktop computer systems and thin client computing, mobile phone technology has not received the deserved attention. Discussing voluntariness in using mobile phone technology in organisations in relation to other technologies is essential especially due to its usage in both working and private purposes. This paper describes the voluntary aspects of using mobile phones in performing activities of the firms in Tanzania and compares it with desktop and thin client technologies. Also, it proposes possible ways of handling such situation in order to improve its use. Among others, the paper has analysed mandotoriness on usage of mobile technology. Further, it highlights key areas which should be addressed in order to improve the usage of mobiletechnology in organisations and eventually cover the gap caused by such mandatory situations.","PeriodicalId":418993,"journal":{"name":"Int.

Farmers who do not practice regular soil tests are facing numerous difficulties such a lack of accurate statistical information for soil and crop management, increased costs for fertilizers, and environmental degradation. However, traditional laboratory testing is costly and laborious, taking up to three weeks to complete. This study presents a technology which integrated various elements into a portable in-field device that measures soil macronutrients of nitrogen N, phosphorus P and potassium K and soil pH. Then it transmits the measured data wirelessly to remote base station for analysis, presentation and storage in real-time. Farmers can access the information from the base station server through their mobile phones. Firstly, the grower can use the test data to provide important indicators into the levels of nutrients in the soil which can be interpreted to stem over-use or under-use and efficiently manage their fertilizer application. Secondly, the system can decrease response time for the grower to implement alterations in the soil nutrient composition. And lastly, it can increase the awareness of precision agriculture, its benefits and usage amongst the average farmer. The results from this test provide important indicators into the levels of nutrients in the soil which can be interpreted to stem overuse or under-use. The grower can use the data compiled to efficiently manage their fertilizer application.","PeriodicalId":418993,"journal":{"name":"Int. J. ICT Res. Afr.

However, existing evaluations methods lack the assessment of user-centric factors such as buying decisions, user experience and user interactions resulting in less than optimum recommender systems. This paper investigates the problem of adequacy of recommender systems evaluation methods in relation to user-centric factors. Published work has revealed limitations of existing evaluation methods in terms of evaluating user satisfaction. This paper characterizes user-centric evaluation factors and then propose a user-centric evaluation conceptual framework to identify and expose a gap within literature. The researchers used an integrative review approach to formulate both the characterization and the conceptual framework for investigation. The results reveal a need to come up with a holistic evaluation framework that combines system-centric and user-centric evaluation methods as well as formulating computational user-centric evaluation methods. The conclusion reached is that, evaluation methods for e-commerce recommender systems lack full assessment of vital factors such as: user interaction, user experience and purchase decisions. A full consideration of these factors during evaluation will give birth to new types of recommender systems that predict user preferences using user decision-making process profiles, and that will enhance user experience and increase revenue in the long run.
