Markov Chain Modelling

AbstractThe telecommunication industry is one of the service industries that is most affected by the problem of subscribers’ churn. Although several techniques have been used to predict customer churn in developed countries, many of those studies used secondary data which are not readily available in Nigeria for researchers. This study investigates how Markov chains help in modelling and predicting the customer churn and retention rate in the Nigerian mobile telecommunication industry. The data generated through the survey were input in the Windows-based Quantitative System for Business (WinQSB) for analysis. The results reveal that in the study area MTN has the highest retention rate (86.11%), followed by GLO (70.51%), Airtel (67%), and Etisalat (67.5%). This result has implications for telecom firms’ strategies for competitive advantage in particular and survival in general.

Abstract Background Recent evidence confirms that mesenchymal stem cells (MSCs) facilitate angiogenesis mainly through paracrine function. Extracellular vesicles (EVs) are regarded as key components of the cell secretome, possessing functional properties of their source cells. Subsequently, MSC-EVs have emerged as a novel cell-free approach to improve fat graft retention rate. Objectives To provide a systematic review of all studies reporting the use of MSC-EVs to improve graft retention rate. Methods A systematic search was undertaken using the Embase, PubMed and the Cochrane Central Register of Controlled Trials databases. Outcome measures included donor/receptor organism of the fat graft, study model, intervention groups, evaluation intervals, EV research data, in vitro and in vivo results. Results Of the total 1717 articles, 62 full-texts were screened. Seven studies reporting on 294mice were included. Overall, EV treated groups showed higher graft retention rates compared to untreated groups. Notably, retention rate was similar following EV- and MSC-treatment. In addition to reduced inflammation, graft enrichment with EVs resulted in early revascularization and better graft integrity. Interestingly, hypoxic preconditioning of MSCs improved their beneficial paracrine effects and led to a more proangiogenic EV population, as observed by both in vitro and in vivo results. Conclusions MSC-EVs appear to offer an interesting cell-free alternative to improve fat graft survival. While their clinical relevance remains to be determined, it is clear that not the cells, but their secretome is essential for graft survival. Thus, a paradigm shift from cell-assisted lipotransfer towards ‘secretome-assisted lipotransfer’ is well on its way.

This paper aims to explore the emergence of ‘Green Banking’ in Bangladesh, with a focus on the role of financial regulation and regulators in greening the financial sector. It also examines the contribution and involvement of banks and non-bank financial institutions in promoting green economic transition. The study is based on the review of secondary data collected from various sources, such as quarterly reports, annual reports, websites of the central bank of Bangladesh, and other commercial banks and non-bank financial institutions as well as various articles, and newspapers reports on green banking in Bangladesh. The collected data is reviewed using descriptive statistics. The research results reveal that the central bank of Bangladesh played a major role in greening the financial system of the country by implementing various green policies and regulatory measures. Although Bangladesh is still far behind the developed countries in terms of environmental performance, the country has made a remarkable progress in initiating and expanding green banking practices, infrastructure development, and accelerating green growth in recent years.

Abstract Background A near-fall is defined as a loss of balance that would result in a fall if sufficient balance recovery manoeuvres are not executed. Compared to falls, near-falls and its associated balance recovery manoeuvres have been understudied. Older adults may not recognise a near-fall or identify the use of their balance recovery manoeuvres to prevent a fall. The consensus on the methods to collect near-fall data is lacking. The primary objective of this study was to determine the feasibility of recruitment and retention. Secondary objectives were to establish evidence that Singapore community-dwelling older adults can identify near-falls and associated balance recovery manoeuvres. Texting and calling methods were explored as reporting methods. Methods This study took place in Singapore (September to October 2019). Participants were healthy, community-dwelling adults aged 65 or older. Recruitment was done through poster advertisement, and all participants gave informed consent. Participants attended a briefing session and reported their near-fall or fall incidence over 21 days using either daily texting or calling. The primary outcome measures were the recruitment rate, retention rate, preferred modes for data reporting and ability to report near-falls or falls. Secondary outcomes included the self-reported incidence of falls and near-falls. Results Thirty older adults were recruited in 5 weeks. All participants completed the study. They understood near-fall concepts and were able to report the occurrence and relevant balance recovery manoeuvres used to prevent a fall. 87% (26/30) chose to text while 13% (4/30) selected calling as their reporting method. One actual fall (0.16%) out of 630 responses was reported. Thirty-six incidents (5.7%) of near-falls were recorded. Sixteen participants (53.3%) experienced near-falls and half of this group experienced two or more near-falls. The use of reach-to-grasp strategy (36%), compensatory stepping (52.8%), and other body regions (11.2%) were used to prevent the fall. Conclusions The study provided evidence that studying near-falls in Singapore community-dwelling older adults is feasible and can be applied to a large-scale study. Recruitment and retention rates were good. Older adults were able to identify near-falls and balance recovery manoeuvres. Both texting and calling were feasible reporting methods, but texting was preferred. Trial registration ClinicalTrials identifier: NCT04087551. Registered on September 12, 2019

Purpose – The purpose of this study is to examine the effect of boards’ demographic diversity on firms’ strategic change and the interaction effect of firm performance. Design/methodology/approach – This paper used secondary data derived from publicly listed firms in Kenya during 2002-2010 and analyzed the data using fixed effects regression model to test the effect of board demographic and strategic change, while moderated regression analysis was used to test the moderating effect of firm performance. Findings – The results partially supported board demographic diversity–strategic change hypothesis. In particular, results indicate that age diversity produces less strategic change, while functional diversity is associated with greater levels of strategic change. The moderated regression results do not support our general logic that high firm performance enhances board demographic diversity–strategic change relationship. In effect, the results reveal that at high level of firm performance, board demographic diversity produces less strategic change. Originality/value – Despite few studies that have examined board demographic diversity and firm performance, this paper introduces strategic change as an outcome variable. This paper also explores the moderating role of firm performance in board demographic diversity–strategic change relationship, and finally, the study uses Kenyan dataset which in itself is unique because most governance and strategy research uses data from developed countries.
