The Impact of In-House Software Development Practices on System Usability in the Social Security Funds in Tanzania

In-house software development is a critical phenomenon for the production of efficient and effective software in generating requisite job output. A few studies have devoted efforts towards establishing the impact of in-house software development on software. Therefore, this paper is an effort towards establishing the impact of in-house software development practices on system usability. In pursuit of this paper, a sample of a sample size of 169, at 95% confidence level, with margin error of 5% was drawn from bold software users, i.e. 300 employees who used the all software including those dealing with the main stream activities. A total of 102 respondents actually responded to the questionnaires. The Online Sample Calculator was used to draw the sample. Quantitative data were collected using semi-structured questionnaires and processed using the SPSS. Descriptive statistics were applied in the analysis. Findings of the study indicate that software development practices, specifically usability test and user involvement in software designing and development had an impact on determining software usability for in-house software. The paper concludes that software development practices shape the design of the software; hence influence usability of the software produced. Recommended is therefore that software usability test and user involvement in software designing and development be promoted for effective software production.

Assessment on LSPU-SPCC Students’ Readiness towards M-learning

Today, the use of technology is a powerful advantage in every field in the society. With the advent of development in information and communications technology (ICT), the process of learning and acquiring new knowledge had undergone a shift marked by a transition from desktop computing to the widespread use of mobile technology. In light of the COVID-19 pandemic, the Commission on Higher Education said that colleges and universities following the new school calendar will no longer require students to attend face-to-face classes. One of the state universities that had been affected by this inevitable situation is the Laguna State Polytechnic University. This study aims to determine the readiness of the students in shifting to m-learning. Specifically, it aims to determine the availability of mobile devices, equipment readiness, technological skills readiness and psychological readiness. A survey-based methodology was used to obtain the data and descriptive statistics to analyze the results. It was determined that almost all of the students own mobile devices, are fully equipped with applications, have high technological skills and are quite ready in terms of psychological readiness.

A Review on Classification of Data Imbalance using BigData

Classification is one among the data mining function that assigns items in a collection to target categories or collection of data to provide more accurate predictions and analysis. Classification using supervised learning method aims to identify the category of the class to which a new data will fall under. With the advancement of technology and increase in the generation of real-time data from various sources like Internet, IoT and Social media it needs more processing and challenging. One such challenge in processing is data imbalance. In the imbalanced dataset, majority classes dominate over minority classes causing the machine learning classifiers to be more biased towards majority classes and also most classification algorithm predicts all the test data with majority classes. In this paper, the author analysis the data imbalance models using big data and classification algorithm.

Challenges for Managing Complex Application Portfolios: A Case Study of South Australian Public Sector Agency

This research explores the challenges in management and the root cause for complex application portfolios in the public sector. It takes Australian public sector organisations with the case of South Australia Police (SAPOL) for evaluation it being one of the significant and mission critical state government agencies. The exploratory research surfaces some of the key challenges using interview as primary data collection source, along with archive records, documentation, and direct observation as secondary sources. This paper reports on the information analysed surfacing eight key issues. It highlights that the organic growth of the technology portfolios, with mission criticality has resulted in many quick fixes which are not aligned with long term enterprise architectural stability. Integration of different mismatched technologies, along with the pressure from the business to always keep the lights on, does not provide the opportunity for the portfolios to be rationalised in an ongoing way. Other issues and the areas for further study are explored at the end.

Human Factors Considerations in Satellite Operations Human-Computer Interaction Technologies: A Review of Current Applications and Theory

Satellite operations are a subset of remote operations that draw similarities with remotely piloted aircraft (RPA) and uncrewed aerial vehicle (UAV) operations. Increased research into boredom, complacency, habituation, and vigilance as they relate to satellite operations is required due to a lack of prevalence in the literature. Circadian rhythms, crew resource management, and shift work dynamics may exacerbate complacency-driven automation bias and social loafing errors in satellite operations. This overview of theory and applications aims to specifically focus on satellite operations literature within human factors research to identify areas requiring an expansion of knowledge. The human-in-the-loop commonality enables human factors lessons to be passed to satellite operations from unrelated sectors to mitigate catastrophic human error potentially. As such, this literature review details the need for increased research in satellite operations human factors.

Implementation of Decision Support Personnel Recruitment System for Laguna State Polytechnic University-San Pablo City Campus

The Laguna State Polytechnic University-San Pablo City Campus viewed the hiring of possible employees as a major problem in the university because it takes time for the human resource department to facilitate the process of recruitment. The main objective of the study is to implement a web-based decision support personnel recruitment system that can screen qualified applicants, assist the human resource personnel in ranking the applicants and generate reports. The system was developed using PHP, CSS, Java Script and XHTML as programming platform and MySQL as database engine. The system design, testing and evaluation procedures were presented. Test results show that the project is secured and can be best viewed in Google Chrome, IE7+, Mozilla Firefox and Opera Mini using personal computer, laptop, tablet and mobile phone. Two questionnaires were distributed - ISO 9126 Software Quality Matrix and acceptability survey to determine whether the implementation was successful. Based from the results of evaluation conducted, the project was rated as excellent with an overall mean of 4.52. The users also agreed that the system was acceptable in terms of interface, operability, security and portability. It was recommended that the system should allow multiple applications for different job vacancies and the ranking of applicants with the same points should be tie regardless of who submitted the application first.

Multi-Agent based Capital Market Management System: A Distributed Framework for Trading and Regulation

Stock Market plays a vital role in the economy of every nation. Having a transparent market may boost the confidence of not only stock brokers but also that of investors. One of the major problems that make investors to shy away from the market is lack of transparency. Another Problem which affect the market regulators is the lack of a system that enable them to check for compliance easily. In this work, an agent based distributed framework is presented. The idea behind the proposed system is that having one system that will serve all the market stake holders will guaranty strict compliance to the market rules, easier to manage and difficult manipulate by the market operators. The implementation of the proposed system followed Multi-Agent Software Engineering (MaSE) Methodology. The evaluation of the system show that, the distributed system developed using Java Agent Development Framework (JADE) is capable of addressing problems of reliability, compliance and transparency.

In order to test the hypotheses, the following three criteria were adequately used: The Medians, the Standard Deviations, as well as the Regression Analysis. The study has reached a number of results; the most notable amongst these results is that there is a positive effect that is statistically significant of information technology on the elements of business transformation in Jordanian communication companies and all of their relating elements. The last decade of the twentieth century and the turn of twenty-first century witnessed significant progress in technology in general and information technology and communication in particular. Such progress still continues until today, accelerating with wide quick strides more than ever. This age has produced many mechanisms for manufacturing knowledge and more advanced technological means that have made the globe as a small village. Communication technology, which is represented by the internet, has played a huge rule in transferring information and technological revolution from the north to the south passing by the east and the west at the same time. All of that have had an impact on all political, economic, educational, teaching, social, media, and advertisement systems in all communities. The term technology is derived from Greek. It consists of two parts, techno, which means skills or art, and logy, which means science or study. Thus, the word technology means the science of performance, science of implementation, or the technical methods to achieve a practical purpose, the science of industrial operation.
