Initial Research

Research on mixed flow turbines spans over 50years with substantial literature available in the public domain. Mixed flow turbines were initially used as an alternative rotor design for gas turbines and later extended to automotive turbocharger applications. The characteristics of a mixed flow turbine resemble a radial turbine but with some significant performance improvements, giving this design an edge to satisfy the ever increasing demand in the automotive sector. The initial research focus was mainly experimental but in recent years, there have been significant contributions in computational analysis. This paper is intended to provide readers with a comprehensive review of the past and present research into the design, performance, and use of mixed flow turbines. Additionally, the future research direction of the mixed flow turbine is discussed in view of the current turbocharger and automotive demand.

Citizen Interactions

The proliferation of e-government adoption in developing nations is anticipated to radically progress governance and transform government-to-citizen interactions and general administrative operations. More so, the benefits and level of e-government adoption in the public sector have been echoed world over; but remains subdued in the context of developing nations. This study investigates the effect of effort expectancy, price value, service quality, optimism bias and behavioural intention on citizens’ decisions to use e-government systems in Zimbabwe. Informed by the extended Unified Theory of Acceptance and Use of Technology (UTAUT2) as a theoretical lens, a research model for this study was adapted and tested using quantitative data collected from a survey of 489 respondents in Zimbabwe. Using confirmatory factor analysis and structural equation modelling, the proposed model was validated, thus, the major contribution of this research. Findings of this study may be of value in policy formulation and restructuring by practitioners on e-government matters. Thus, the results shade a light to some of the key drivers and inhibitors of e-government adoption in developing nations. Despite achieving its aim, this study has its limitations which constitute the future research direction

AbstractThe paper contributes to debates on non-profit strategy, first by arguing that intellectual capital (IC) can be utilised as a non-profit strategic management conceptual framework and second by highlighting nuances in the meaning and significance of IC. In responding to the public management agendas of government, non-profit organisations (NPOs) have had to commercialise their strategies. On the basis of data from in-depth interviews with 35 senior non-profit managers across 22 large Australian social service non-profit organisations (SSNPOs), the analysis confirms that IC assists SSNPOs in managing the social–commercial divide, but that managers' understandings of the IC concept are often different to those contained in the IC literature. IC scholars suggest that IC is synergetic with its components being inter-dependent. The managers perceived that very few inter-relationships existed between IC components. Implications of the theory—practice divide for non-profit strategy are discussed. Research limitations and future research direction are presented in the paper.

Spatial System

Africa is the last of the major global regions to urbanize and to economically benefit therefrom largely due to centuries of the fragmented spatial system by geographic, trading zone, colonial experiences, and logistics barriers. Recently, however, the integration of African urban spatial structure was spearheaded by the private sector under the guidance of the public sector. This chapter analyzes the goals driving integration, the tools used by private and the public sectors in setting the stage for integrative urban growth through industrialization, and then identifies the future opportunities and challenges in sustaining the momentum. The chapter comprises of an introduction, a conceptual framework, the gluing elements, the review of the development guidance system, opportunities and challenges ahead, future research direction, and conclusion.

Surface Protection

Gas turbines (GTEs) are often utilised in harsh environments where the GT components, including compressor vanes and rotor blades, are subject to erosion damage by sand and dust particles. For instance, in a desert environment, the rate of damage made by solid particles erosion (SPE) becomes severe, and therefore results in degradation to the GTE parts, lowering the cycle efficiency, reducing the device lifetime, and increasing the overall cost of the operation. As such, understanding the erosion mechanism caused by solid particles and the effects associated with it is crucial for selecting the appropriate countermeasures and maintaining the system performance. This review paper provides a survey of the available studies on SPE effects on GTEs and surface protective coatings. Firstly, the ductile and brittle SPE mechanism is presented, as well as the ductile-brittle transition region. Then, an in-depth focus on the parameters associated with the SPE, such as particles properties and impingement conditions, is introduced. Furthermore, the existing theoretical models are shown and discussed. Afterwards, erosion resistant coating materials for surface protection and their selection criteria are covered in the review. Finally, the gap in knowledge and future research direction in the field of SPE on GTEs are provided.

Heuristic Information Processing

Abstract. Comments sections under news articles have become popular spaces for audience members to oppose the mainstream media’s perspective on political issues by expressing alternative views. This kind of challenge to mainstream discourses is a necessary element of proper deliberation. However, due to heuristic information processing and the public concern about disinformation online, readers of comments sections may be inherently skeptical about user comments that counter the views of mainstream media. Consequently, commenters with alternative views may participate in discussions from a position of disadvantage because their contributions are scrutinized particularly critically. Nevertheless, this effect has hitherto not been empirically established. To address this gap, a multifactorial, between-subjects experimental study ( N = 166) was conducted that investigated how participants assess the credibility and argument quality of media-dissonant user comments relative to media-congruent user comments. The findings revealed that media-dissonant user comments are, indeed, disadvantaged in online discussions, as they are assessed as less credible and more poorly argued than media-congruent user comments. Moreover, the findings showed that the higher the participants’ level of media trust, the worse the assessment of media-dissonant user comments relative to media-congruent user comments. Normative implications and avenues for future research are discussed.

Internal And External Factors

Economic performance of a country is mostly determined by the growth and any other internal and external factors. In this study, researchers purposely focused on Malaysian market by examining the relationship between export, inflation rate, government expenditure and foreign direct investment towards economic growth in Malaysia by applying the yearly data of 47 years from 1970 to 2016 using descriptive statistics, regression model and correlation method analysis. By applying Ordinary Least Square (OLS) method, the result suggests that export, government expenditure and foreign direct investment are positively and significantly correlated with the economic growth. However, inflation rate has negative and insignificant relationship with the economic growth. The outcome of the study is suggested to be useful in providing the future research direction towards the economic growth in Malaysia.
