Aspect of Desire in Enhancing Electronic Resource Utilization among Postgraduate Students at Universities in Meru County
(International Journal of Professional Practice, 2024) Shindemburi,Mercy; Gichohi, Paul; Gatimu, Winfred
The global shift to virtual libraries and e-learning has significantly increased the use of electronic resources in university libraries, particularly for postgraduate students. Customizing these services can enhance the "Desire" component of the AIDA model, promoting availability, regular updates, perceived value, and convenience. However, empirical investigations reveal that e-resources are underutilized. This paper presents some of the results of a large study that looked at how adoption of the AIDA model can enhance utilization of e-resources among postgraduate students in universities in Meru County. It assessed the desire of postgraduate students for e-resources. It employed a mixed method approach with a descriptive survey research design. The target population comprised of departmental heads and post-graduate students. Purposive sampling technique was employed to obtain librarians, while stratified random sampling and simple random sampling method was used to select students. A sample size of 260 postgraduate students and 13 departmental heads was obtained. Data was collected using questionnaires and interview guides, with quality ensured through construct, content, and face validity checks; while reliability was measured using Cronbach's alpha. Data was analyzed by computing mean, standard deviation, and correlation analysis to test relationship, while qualitative data was analyzed thematically. There was a positive correlation between postgraduate students' desire and e-resources utilization. However, in Meru County university libraries', desire is moderate. This can be enhanced by improving resource quality, staff communication, sensitization, user experiences, marketing strategies, and technological infrastructure. The study recommended university libraries to strengthen training programs, resource marketing, promoting e-resources' benefits, and integrating them into the curriculum to enhance postgraduate students desire for e-resources.

How Public Library Information Resources Impact Maize Production in Laikipia East Sub-County, Kenya
(Journal of Information and Technology, 2024) Maina, Susaide; Gichohi, Paul; Gatimu, Winfred
Purpose: Kenya's economy is still based mostly on agriculture, with maize (Zea mays) being essential to rural populations' livelihoods and food security, especially in Laikipia East Sub-County. The problem was that maize farmers had a history of significant crop failure, as seen by the 12.8% drop in the total amount of maize harvested in 2023 over 2022. The goal of the current study is to ascertain how public libraries in Kenya's Laikipia East Sub County might improve maize production. The purpose of this study is to investigate how the Laikipia East Sub-County's public library information resources affect the methods used in maize growing. The research was guided by the Information-seeking Behavior Theory. Methodology: The survey method was utilized in this cross-sectional study. A population of 12,500 maize farmers from Laikipia East Sub-County was considered; where the simple random selection of 373 participants was taken as a sample for the study. A sample of 3 library staff was obtained from a population of 10 using a purposive sampling technique. Questionnaires and interview guides were used to collect the data. Mean and standard deviation were computed from data gathered through questionnaires, while, themes were identified from interview data. Results: The findings reveal that while public libraries in Laikipia East Sub-County provide resources for maize farming, many farmers view these resources as outdated or insufficient, pointing out need for updated agricultural information, better digital resources, targeted training programs, and increased awareness of available library services. Public libraries in Laikipia East Sub-County provide valuable resources for maize farming, but there's a gap between available information and farmers' needs. Conclusion: Libraries should update content, improve digital access, and tailor services to address farming challenges. The study recommends need for maize farmers to utilize digital resources from public libraries to enhance maize output and improve agricultural practices

Defect dependent memory switching in amorphous silicon alloys [a-Si xC1-x:H]
(Electronics Letters, 2002) Shannon, J.M; Gateru, Robert; Gerstner, Ed
It is shown that memory switching in amorphous silicon alloys is affected by ion bombardment. In particular, ion damage lowers the voltage required to form devices and switch them into the on-state. This technique enables optimised non-volatile memory devices to be made with improved switching ratios.

Polarity-dependent forming in ion bombarded amorphous silicon memory devices
(Journal of Applied Physics, 2005) Gateru, Robert; Orwa, J.O; Shannon, J. M.
Polarity-dependent forming in ion bombarded metal±semiconductor±metal (MSM) memory devices of hydrogenated amorphous silicon is reported. It is shown that prior to ion bombardment, current transport in the MSM devices is asymmetric and is controlled by the Schottky barriers at two MS junctions. Upon bombardment, however, there is a bulk component to the current and the I±V characteristics of the devices become symmetric at low bias voltages. The forming voltage in the bombarded devices shows polarity dependence. For positive bias applied on the top contact, we ®nd that devices form at the same electric ®eld independent of the thickness of the amorphous silicon while for negative voltage on the top contact, the electric ®eld needed for forming increases with the thickness. A model involving the difference in energy deposition and heat sinking for the two polarities is proposed

Effects of Credit Card Incentives on Consumer Borrowing In Kenya: A Case of Commercial Banks in Kenya
(International Journal of Academic Research in Economics and Management Sciences, 2017) Mwende, Joyce; Wachira, David Muturi; Amata, Evans Ombima
Financial institutions have mainly relied on incentive programs as their main strategic driver to increase electronic payments, such as through use of credit cards. Credit cards have been globally acclaimed for their benefits that range from their ability to ensure tax-compliance, security, instant cash and their ability to facilitate settlement of cross-border transactions. However, there exists a great challenge of credit card usage, such as ease of accumulation of debts and high interest charges. The purpose of this study was to determine the effect of credit card incentives on consumer borrowing in Kenya. The study employed a descriptive study approach using a sample size of 18 commercial banks offering credit card services. Selfadministered questionnaires were used to collect information. Credit card incentives were found to be a major contributor to credit card uptake. The study also found that most banks used incentives such as rewards for repeated use, low interest rates, traveling awards and benefits to influence the spending behavior of their clients. The study found credit card also affected spending behavior. It is concluded that credit card incentives can be effectively used by banks to increase use of credit cards. It is recommended that financial institutions should educated their customers on how to use their credit cards so that they do not fall into a debt trap.
