Abstract: The study was to isolate and identify bacteria on mobile phone screen from some students of Novena University. Thirty samples were collected by using wet sterile swabs in transporting media to detect the presence of bacteria. A total of thirty samples per sex of students (15 males and 15 females) were collected. The swabs have been cultured on a different media in order to determine the bacteria on these devices. The study results showed that mobile phone devices from students (females and males) have been contaminated with bacteria isolates. Out of 30 samples, 13 (14.33%) for both males and females were contaminated with Staphylococcus and Eschericha spp. The results show that Staphylococcus (53.85%) is more prevalent than Eschericha spp. (46.67%). It is recommended that good hygiene practices should be observed by students to avoid spread of pathogen from phone devices.
Impact of Information and Communication Technologies (Icts) On Agricultural Productivity among Smallholder Farmers: Evidence from Sub-Saharan African Communities (Published)
The study was carried out to assess the impact of Information and Communication Technologies (ICTs) among smallholder farmers in Northern Nigeria during October 2015 and September 2016 cropping season. Data were collected with structured questionnaires distributed to 200 smallholder farmers. The study used a multiple stage random sampling procedure to select farming household. Likert type scales were used to analyze the data. The main aim of the study was to find out the impact of ICTs on the agricultural productivity and welfare of the respondents. The t-test result revealed that ICT Services Short Message (SMS text reminders) had positive and significant impact (P<0.001**) on the agricultural productivity of smallholder farmers. The findings showed that 52% of the respondents experienced rapid increases in their crops productivity; and improved standard of living of the farmer as a result of the ICT Services Short Message (SMS text reminders). In addition, a large proportion (92%) of the respondents revealed that ICT Services Short Message (SMS text reminders) are beneficial to them. The results also revealed that radio, mobile phone and television among others were the most available ICT devices to the smallholder farmers in the area. However, the results obtained showed that radio and mobile phone were the most readily available ICT device with 97% and 85.8% respectively. The study however recommended that the Federal Government should create an enabling environment towards improved rural infrastructure and access to internet and other mobile communication technologies for rural people which would improve the overall use of ICT facilities. In addition, the Nigerian Government should establish ICT training centers in all the rural areas and educate farmers on the benefits of ICTs. Lastly, the study also suggested that there is a need for the development of ICT skills among agricultural extension workers and farmers in rural Nigeria
This study was conducted to investigate the attitudes of college students toward mobile phone usage in Nigeria. Six hundred and forty randomly selected 300- and 400- level students of the University of Ibadan, Oyo State and the Federal Polytechnic, Ilaro, Ogun State were involved in the study. The study was conducted in a classroom environment during the schools’ continuous assessment (CA) week. After information was collected from the students, their test scores were obtained from their faculties. The test scores were compared to the scores obtained from the questionnaires. It was realized that the academic discipline of the college students as well as their area of residence do not make them perceive or use their mobile phones differently. Also, gender was found to be an important determinant of mobile phone usage among the students. In addition, no significant relationship was established between the mobile phone usage and their academic performance. It was then recommended that operational involvement and practical prevention programs, which would discourage mobile phone addiction in students, should be developed and configured in all cell phones. Also, management of colleges must constantly inform and reorient their students about the negative and positive effects of their mobile phone uses. In addition, authorities of the schools as well as policy makers must formulate rules for students to concentrate on their lectures totally without fiddling with their mobile phones during lectures
Technology has been evolving since the foundation of the world, from the mastery of fire by man to supercomputers, the electronics and nuclear weapons of the twenty first century and the most recent includes the print, telephone and the internet. These recent technologies have improved communications on a global scale in various areas such as advanced economy, development of destructive weapons, unwanted by-products, and privacy encroachment. Questions have been raised on whether technology improves the society or worsens its existence. This paper investigated the opinion of people on the age range who mostly use modern technology about the negative effects of technology on Nigerian society. The study used questionnaire to gather data from students of higher institution in Rivers State. These students come from different states of the federation, thus making the sample representative of Nigerian society. It was discovered that the problem is technological addiction which leads to isolated generation, over reliance, and obsession. This paper argued that over usage of modern technology or inappropriate usage yields negative effects on the user and advised that users should be self-disciplined when using them.
MOBILE PHONE USAGE AMONG NIGERIAN UNIVERSITY STUDENTS AND ITS IMPACT ON TEACHING AND LEARNING (Published)
In Nigeria, mobile phones have been instrumental to the rapid increase in telecommunications accessibility. Mobile phones have become integral part of daily life among the general population and college/university students. Several studies have found that the use of mobile phones among college/university students has brought about a profound and diverse pool of knowledge. However, mobile phone usage also has its adverse effects. This paper examined the evolution of mobile phones in Nigeria and the concomitant positive and adverse effects of its usage amongst students in tertiary institutions. It identified the positive effects to include easy access to information, instructional usage and personal convenience; while the adverse effects include distraction in the classroom, reduced cognitive ability, cheating during examinations, cyber bulling, poor writing skills and addiction. The paper then concluded that though mobile phones have positive effects on the educational and socio-economic development of Nigerian students, university authorities should take a more proactive role to reduce its adverse effects by either prohibiting the use of mobile phones during lecture hours or encouraging students to switch off their phones or put them on silence mode while receiving lectures. The significance of this paper for the Nigerian educational system is that if its recommendations are implemented, the positive effects of mobile phone usage will then overshadow its negative effects
Speech user interface has the potentials to accommodate different users irrespective of the level of education. This type of user interface can provide interactions that meet the capabilities of low literacy users in underserved rural communities. One of the challenges facing the development of Information and Communication Technology in rural underserved communities is the inability of the users to interact and communicate with the services provided effectively. The task of designing user interfaces to accommodate low literacy users is still a big challenge. We conducted a study with the aim of designing a customized speech user interface to enable low literacy users in a rural community to interact and have access to a mobile commerce service. We applied different ethnographic research methods in the process of data collection, design and evaluation of the user interface. The user evaluation results show that the users were able to successfully interact with the application. The users feel that the speech user interface is easy to understand and use, and the interface meets their capabilities
