Issues and perspectives of capacity development in embodied energy indices for building materials sourced in Nigeria: A review
Authors: Nwanya S.C. , Ononiwu H.N. 
Published: March 2021

Embodied energy (EE) property of building material is a great determinant of the performance of a building. The dearth of information on EE of locally sourced building materials (LSBMs) constitutes a challenge to affordable housing in Nigeria. In this paper, a review of the previous literature, unfilled gaps in those works, and future directions in embodied energy research for LSBMs is presented to evolve a Nigerian perspective. A constructive non-meta analytic methodology was adopted for the paper. This was followed by classification and comparison of snapshot literature in the embodied energy of building materials. Insightful sources of information for the study were drawn from a vast body of knowledge both documented literature and some interviews with knowledgeable personnel in the area of a built environment. From the survey, energy management opportunities were revealed, which would not have been apparent from a specific building case study alone. There are distinctions in the literature with this currentpaper for a Nigerian case study: none have addressed the embodied energy coefficient of materials. Also, the status of embodied energy studies, for these materials, is at a low profile and the few investigations carried out focused on life cycle operating energy of buildings. These research gaps evidently imply abundant research opportunities that await exploitation in the building industry. This paper adds to an existing body of knowledge on the use of EE index to promote and optimize the selection of LSBMs as alternative to imported building materials. We hope engineers, estate developers and architects would find it useful for making an informed decision in the design of resilient buildings using indigenous materials.

Media motion-based resource distribution for mobile video networking
Authors: Ukommi U.S. 
Published: March 2021

Wireless video communication is challenging due to vulnerability of media bitstreams to channel distortions. Investigation has been carried out on wireless video channel under tight networking resource budget. One of the challenges is the impact of channel errors on the quality of media streams with high motion activity. Motion activity in this context defines the magnitude of activity displacement in video sequence. Based on the analysis, Media Motion-based Resource Distribution (MRD) is proposed to maximize the average received video quality over wireless system, by regulating the resource distribution of the media streams based on their motion activity characteristics. Experimental results demonstrate that the proposed scheme can improve the average received video quality performance under tight resource constraints budget.

Published: March 2021

This research investigates the reliability of Anogeissus schimperi timber specie grown in North Western Nigeria as a bridge beam in shear and bearing forces. Specimens for laboratory tests were prepared using the timber specie in accordance with BS 373 (1957). Tests were carried out to determine the physical and mechanical properties at 12% moisture content in line with BS 5268 (2002). Statistical analysis was carried out using strength properties obtained and the specie was classified to strength class D60, confirmed to be Hardwood. Anogeissus schimperi timber bridge beam was designed in accordance to BS5268 (2002), using deterministicapproach. While, reliability analysis to confirm the safety level of the timber bridge beam designed was carried out using constant failure rate model in accordance with Jimoh, (2018). Sensitivity analysis to ascertain the safety margin of a simply supported timber bridge beam subjected to Shear and bearing by varying the span, depth, width and live load was carried out. Results of reliability analysis showed that Anogeissus schimperi met the minimum reliability index of 0.5 under ultimate state of loading in Shear and bearing. Safety index was found to be directly proportional to the depth and width but inversely proportional to the span and live loadof the timber bridge beam during Sensitivity Analysis. The result confirmed that Anogeissus schimperi specie from north western Nigeria at 400mm depth, 150mm breadth and 5000mm span under ultimate limit state loading in Shear and bearing can be used as a reliable timber bridge beam material.

Published: March 2021

Few interventions addressing student wellbeing have been designed or evaluated specifically with doctoral students in mind despite the doctoral experience being distinct from that of other students. We therefore explore the benefits of interventions designed specifically to address a key source of stress or anxiety for doctoral students, namely thesis writing.
This research uses a mixed-methods approach to explore the ways in which doctoral thesis writing support sessions, in the form of writing workshops or writing retreats, can reduce the stress and anxiety associated with thesis writing specifically or academic writing more generally. Firstly, we quantified the reduction in writing related stress and anxiety associated with workshop participation using a survey completed before and after workshop attendance. Subsequently, we gathered student experiences of workshop participation through focus group interviews.
Survey responses showed a clear reduction in participants’ levels of stress and anxiety related to thesis writing and focus group respondents described many clear benefits of participating in writing support sessions. We conclude that participation in thesis writing workshops and writing retreats is a valuable strategy for reducing stress and anxiety associated with thesis writing. The sense of empowerment and confidence that comes from discussing thesis writing in a supportive environment with others in the same situation, and the opportunity to experiment with new tools and strategies, is very valuable for improving the wellbeing of doctoral students.

Authors: Kinoti Dr. Mary Kathambi , Kinoti Luke Mwiti 
Published: March 2021

Purpose: The study aimed to establish the impact of social entrepreneurial support on social-economic empowerment of households and a case study of Riziki Kenya was taken.
Methodology: The study used a descriptive survey design and the target population for this study was Riziki managers and staff as the key informants, the 230 supported entrepreneurs (households) and 22 supported micro-enterprises groups in Kibra Sub-County. The study employed multi-stage sampling which included purposive and simple random sampling. The study collected primary data using questionnaires. Key Informants included six Riziki Kenya managers and staff members. The use of interviews guides enabled the researcher to solicit the required information from supported entrepreneurs, key informants and group micro-enterprises. Statistical package for the social sciences (SPSS) was used to analyze quantitative data from questionnaires and the results presented in tables, graphs, charts and narratives to answer the research questions. Qualitative data was organized into themes and patterns categorized through content analysis to capture emerging thoughts.
Results: Riziki Kenya has empowered households to improve their standards of living. Even with their small businesses, they could feed their families and pay bills. Empirically, the study has shown that social entrepreneurial support positively impacts the business of households which in turn improves the living conditions of families that own such enterprises. Access to credit facilities by small businesses helps such enterprises to grow and by extension, this improves the households’ finances and ability to get nutritious food, a good shelter, better education and better health care.
Contribution to theory, policy and practice: The paper suggests that the appropriate model and theoretical approach for social entrepreneurial impacts would be to direct resources to household owned business which would grow and in turn affect the prosperity of the households. In practice, social entrepreneurs and their staff should increase the support to households partnering with other NGOs to train on the basic entrepreneurial and business management skills to improve their enterprises, increasing access to funds and any other intervention strategies. Policymakers should enact laws that encourage the growth of social entrepreneurship since doing so increases the likelihood of successful small enterprises and this finally impacts positively on the social-economic empowerment of households.

Published: March 2021

With the advent and active development, social networks have gained the attention of a million audience. Now it is difficult to imagine a person who does not have a profile in at least one social network. The use of social media has become a daily routine: some use sites and applications to maintain existing social connections, others - to find people with similar interests, views, activities or other motivating factors [1].
The purpose of this study is to establish the factors that influence the level of perception of the message by the audience in social networks.
In this work, a quantitative research method is used. The relationships were established using correlation analysis. To analyze the data obtained, the SmartPLS software was used, which makes it possible to highlight the characteristics that have the greatest impact on the manifestation of initiative behavior.
The novelty of the research lies in the fact that for the first time the factors influencing the level of perception of messages from Kazakhstani opinion leaders by the audience in social networks were studied.
The results of this study are of high theoretical significance, as they can be used in teaching disciplines such as Internet marketing, digital marketing, consumer behavior and strategic marketing.
In addition, this study is notable for its practical benefits, since the conclusions drawn contribute to the formation of a competent online marketing strategy in the enterprise

Published: March 2021

Abstract. The power generation and loading dynamic responses of a 2.2 m diameter horizontal axis wind turbine (HAWT) under some of the IEC 61400-1 transient extreme operational conditions, more specifically extreme wind shears (EWSs) and extreme operational gust (EOG), that were reproduced at the WindEEE Dome at Western University were investigated. The global forces were measured by a multi-axis force balance at the HAWT tower base. The unsteady horizontal shear induced a significant yaw moment on the rotor with a dynamic similar to that of the extreme event without affecting the power generation. The EOG severely affected all the performance parameters of the turbine.
