Corporate governance and company performance across Sub-Saharan African countries
2013
Accepted version of an article from Journal of Economics and Business This paper examines the extent to which publicly listed companies across Sub-Saharan African countries have adopted “good corporate governance” practices. We investigate the association of these practices with companies’ accounting performance and market valuation. The findings indicate that companies across Sub-Saharan Africa have only partly implemented good corporate governance practices. We find a positive association between our constructed index of good corporate governance practices and accounting performance. However, we find a negative association between the corporate governance index and the market valuation. W…
Assessment of Mobile Money Enablers in Nigeria
2018
This chapter describes how mobile money is an emerging and innovative financial service delivery mechanism. With huge success, recorded mostly in the developing economies, it is scholarly unclear the antecedents of its adoption. Using a survey of 151 respondents comprising both the banked and underbanked in the South-Western part of Nigeria, the authors used the PLS-SEM to test the research hypothesis. The results reveal the enablers of mobile money, which are social influence, performance expectancy, security and effort expectancy, and inhibitors such as system anxiety and cost. Privacy, trust, image and convenience were not found significant in this study. Social influence, performance ex…

Financial Behaviour Under Economic Strain in Different Age Groups: Predictors and Change Across 20 Years
2021
AbstractThe present study examined the multiple micro- and macro-level factors that affect individuals’ financial behaviour under economic strain. The following sociodemographic and economic factors that predict financial behaviour were analysed: age group, year of data gathering, and attitudes towards consumption (economical, deprived, and hedonistic). Subjective financial situations and demographic characteristics were controlled for. Finnish time series data that consisted of five cross-sectional nationally representative surveys were used (n = 10 043). The analyses revealed four types of financial behaviour: cutting expenses, borrowing, increasing income, and gambling. Young adults aged…
The use of language in migrant stay-at-home parents’ process of integration : Experiences of inclusion and exclusion
2017
This paper examines the use of language and how it contributes to the experiences of inclusion and exclusion of recent migrant stay-at-home parents in Finland. The study shows how the use of language facilitates the integration process of newly arrived stay-at-home parents of migrant background and affects their experiences of social inclusion and/or exclusion. The study uses the translingual approach (Canagarajah, 2013) to shed light on the multilingual reality migrants are faced with in their new surroundings. The approach is ethnographic and the data is interpreted using data-driven conventional content analysis (Tuomi & Sarajärvi, 2009, pp. 108–113). The results suggest that English wor…
Dimers of the Higher-Energy Conformer of Formic Acid: Experimental Observation
2012
We report on the first experimental observation of formic acid dimers composed of two molecules of the higher-energy cis conformer. The cis–cis formic acid dimers are prepared in an argon matrix by selective vibrational excitation of the ground state trans conformer (deuterated form HCOOD) combined with thermal annealing of the matrix at about 30 K. Five cis–cis formic acid dimers are predicted by ab initio calculations (interaction energies from −16.9 to −27.2 kJ molˉ¹), and these structures are used for the assignment of the experimental spectra. Selective vibrational excitation of the obtained cis–cis dimers leads to the formation of several trans–cis dimers, which supports the proposed …

Kondo Resonance in a Mesoscopic Ring Coupled to a Quantum Dot: Exact Results for the Aharonov-Bohm/Casher Effects
2000
We study the persistent currents induced by both the Aharonov-Bohm and Aharonov-Casher effects in a one-dimensional mesoscopic ring coupled to a side-branch quantum dot at Kondo resonance. For privileged values of the Aharonov-Bohm-Casher fluxes, the problem can be mapped onto an integrable model, exactly solvable by a Bethe ansatz. In the case of a pure magnetic Aharonov-Bohm flux, we find that the presence of the quantum dot has no effect on the persistent current. In contrast, the Kondo resonance interferes with the spin-dependent Aharonov-Casher effect to induce a current which, in the strong-coupling limit, is independent of the number of electrons in the ring.
Deception and Abuse: Manifold Instances of Proximity Violence Against Sub-Saharan Women
2020
This chapter, by referring to the gender-violence binomial, highlights some of the dynamics between “resistant victims” and “proximate perpetrators” which characterize proximity violence. It presents the results of research consisting in participant observation of 18 sub-Saharan women residing in refugee facilities located in western Sicily and 16 non-directive interviews, from which three cases have been extracted.
