Value Propositions of Implemented e-Government Projects: Towards Developing a Framework From a Systematic Review

This study aims to develop a framework that identifies and measures the value propositions of implemented e-Government projects. Consequently, the study conducted a systematic review using a concept-centric and thematic approach by reviewing 84 articles as primary research data. In doing so, it identified: (1) effective public organizations; (2) quality service delivery; (3) open government and democratic value; and (4) social value and well-being. Furthermore, two gaps were identified, namely a dearth of studies on the measures well as actualization, and sustainability of the value propositions. The study synchronized the identified value propositions to develop a framework for value propositions of implemented e-Government projects. While multiple theoretical perspectives were advocated for this includes affordance actualization theory grounded in realist evaluation and self-determination theory. This was done to uncover the contextual conditions and mechanisms that will foster the actualization and sustainability of the identified value propositions of implemented e-Government projects as a future research direction

Traditional and Information Technology Anti-Corruption Strategies for Curbing the Public Sector Corruption in Developing Economies of Sub-Saharan Africa: A Systematic Literature Review

The pervasiveness of public sector corruption has been a major concern by successive governments and their citizenry. In order to curb such corruption, previous studies have focused on the anti-corruption strategies adopted by governments in isolation, but little or no study has focused on the interactions of the anti-corruption strategies. Using the concept-centric approach, we reviewed 91 studies systematically to understand the trends of government anti-corruption strategies. From the synthesized studies, we identified three dominant themes of anti-corruption strategies and their associated concepts. In addition, we also identified one dimension that captures information technology (IT) as a vehicle that enhances corrupt practices in the public sector. The identified themes include traditional, technological, transparency, and accountability anti-corruption strategies. We leveraged the identified themes and their associated concepts to develop a conceptual model that could explain the trends of anti-corruption strategies for curbing the public sector corruption. Our findings suggest that there are things we still need to know, particularly in the case of IT anti-corruption strategies that have been misused for corrupt purposes, especially in the context of e-government systems’ adoption in the public sectors as a new stream of IS research

Evaluation of Facies Architecture and Depositional Environment of G-Field in the Greater Ughelli Depobelt of the Niger Delta Area, Nigeria

This study utilized well logs and core data to evaluate facies architecture and depositional environment of G-field in the Greater Ughelli Depobelt of the Niger Delta area in Nigeria. The study revealed five lithofacies unites, namely, Bioturbated Sandstone Facies (BSF), Coarse to Pebbly Sandstone Facies (CPSF), Mudsone Facies (MF), Very Fine Grained laminated Sandstone Facies (FGLSF), and Wavy- to Flaser-Bedded Facies (WFbF). The lithofacies were grouped into Two (2) Facies Assemblages that where established from the five mentioned lithofacies A-E. The Facies Assemblages are Open-marine Facies Association, Brackish-water Marginal-marine Facies Association and Tidal Flat Association. Gamma Ray (GR) logs within the cored interval defined an aggrading deposit. These assemblages were used to infer the various environments responsible for the deposition

Production of Activated Carbon from Carbonaceous Agricultural Waste Material: Coconut Fibres

Activated carbon was produced from Cocos nucifera (coconut) fibers by carbonization and activation processes. The sample was first pretreated before carbonization and activation processes at 450°C and 700°C respectively in an electric furnace. Chemical activation using Potassium hydroxide (KOH) 4:1 (weight basis) was carried out to increase the activated carbon adsorption properties. The element contained in the sample was analyzed using the Energy Dispersive Spectroscopy (EDS) while the surface morphological composition was determined by Scanning Electron Microscope (SEM) and the chemical bonds present in the sample was characterized using Fourier transform infrared reflection (FT-IR). From the research carried out, the results show that activated carbon produced from coconut fibers would be useful and effective for adsorbent purposes, considering its large pores

Theory Choice In Critical Realist Information Systems Research

There has recently been calls for Information Systems (IS) researchers to revisit the dominant mode of theorizing in IS research practice, a process often reduced to “shopping” around for an appropriate theory among a diversity of competing theories. To answer this call, this paper examines the process of theory choice from a critical realist perspective, and in so doing develops guidelines for middle-range theorizing in critical realist IS research. Three steps are identified in this process, these being to (1) understand the background theories relevant to the phenomenon under investigation, (2) contrast and combine these background theories, and (3) situatedly integrate the background theories. The process is illustrated by demonstrating its use in a case study of the emergent usage of adaptive IS

Embodied Energy and Carbon footprints in Residential buildings

To satisfy the housing needs of an ever increasing population, the construction of buildings have become a large consumer of a considerably large amount of energy and resources. This human activity as well as other industrial and domestic activities if left unchecked will result in the gradual deterioration of our environment. The term embodied energy has been developed as a means to measure the energy expended during the life cycle of a building material. This life cycle consists of mining and processing of raw materials, production processes which transforms the raw materials to the desired building material, transportation to site, construction and finally demolition. The use of embodied energy as a measurement tool is currently being applied in other industrial sectors such as manufacturing and road construction. This paper aims at calculating the embodied energy and carbon footprint of a 1 bedroom 1 storey flat. Results obtained from this analysis reveal that the embodied energy and carbon of the case study building is 2878.32MJ⁄m^2 and 367.21〖kgCO〗^2/m^2 respectively

Application of Discrete Event Simulation in Industrial Sectors: A Case Study

Discrete Event Simulation (DES) has become a useful tool in the evaluation of changes that may bring positivity to manufacturing and process organizations for both goods and services provision. The main focus of any business entails the reduction of cost and lead time while increasing profits and this is why refining of production processes is essential. This paper reports the application of DES in two case studies. The case studies selected for the implementation of Discrete Event Simulation are a packaging company and a local mobile phone service provider using the software FlexSim. The implementation aims at showcasing the versatility and its ability to provide the relevant data to make more informed decision while optimizing the entire processes involved in production

Antibody profile in laying birds vaccinated with Newcastle disease vaccine, La Sota

Newcastle disease (ND) is endemic in Nigeria and constitutes a major problem to poultry production especially commercial egg production. Despite vaccination of birds, some farmers and other stakeholders still believe that there is shortened protection interval between vaccinations leading to frequent outbreaks. This work studied the antibody profile in vaccinated birds using Newcastle disease vaccine, La Sota (NDVL) with a view to establishing the rise and decline in antibody titre after vaccination and thereby determining the protection interval in our local environment. Two hundred and eighty (280) Shaver brown layers at 78% hen house production were used for the experiment. When their antibody levels were at Geometric Mean Titre of 12.1, they were vaccinated with NDVL through the oral route. On a monthly basis, the antibody titre was determined and 80 birds were taken to a distant location and challenged with a velogenic strain of Newcastle disease virus (NDV). Results showed good protection at 4 weeks, fair protection at 8 weeks and no protection at 12 weeks post vaccination (PV). We therefore recommend that under the Nigerian condition, laying flocks should be revaccinated at 7-8 weeks interval with NDVL

Promoting Learning through Interaction: Examples from the English Language Classroom

Classroom interaction is helpful for language learning. Every learner is expected to develop competence in English language learning, in order to function effectively in the multilingual Nigerian setting. English as the official language in Nigeria occupies an important position. Considering the importance, role and functions of English in Nigeria the primary goal of the English language curriculum is that learners should acquire communicative competence in English. From our observation we found that learners learn more comprehensively through classroom interaction. This research also discovered that applying the basic principles of interactive language teaching can promote learners initiative and autonomy, which in turn begets linguistic and communicative competence. To achieve this goal, the curriculum recommends the communicative language teaching approach for teachers of English; to enable learners achieve communicative competence in the use of the English language. Teaching through interaction enhances observation, using apt methods, strategies and resources which in turn promote learners autonomy and initiative. This study thus, emphasizes the need to use interactive strategies in order to enable students to use, practice and achieve fluency in the language. This paper therefore, explores some interactive strategies applied in the classroom with a focus on re-tooling English language teachers for more productive teaching and learning.
