Determinants of equity changes in partial acquisitions of Finnish multinationals in foreign markets
Purpose – When entering foreign markets, multinationals can acquire part of a foreign firm and can increase or decrease their equity stake over time. However, extant studies have mainly focused on equity stake acquired during initial market entry. The paper aims to discuss this issue.
Design/methodology/approach – This study fills this gap by using the Uppsala model to analyze six cases of international acquisitions of Finnish multinationals in global markets.
Findings – The authors found that firms change their equity stake in partially acquired foreign subsidiaries: when they have learned about the host country and businesses of the partially acquired firms, when they have gained target-specific experience, when they build trust and ensure relationship commitment and finally, when they jointly develop and exploit opportunities.
Originality/value – This study is one of the first to apply the Uppsala model to empirically analyze international acquisitions, thus paving the way for behavioral and process-oriented approaches. The study contributes to knowledge of post-entry strategies of multinationals.©2019 Emerald Publishing Limited.

International joint ventures research on Africa : A systematic literature review, propositions, and contextualization
This study reviewed the research on international joint ventures (IJVs) in Africa up to 2017. The authors performed a systematic search of peer-reviewed good quality research using the 6W procedure and ensuring the quality of the review by using the 5Cs quality criteria. The content analysis was focused on four research questions. A total of 22 relevant studies were found. Overall, only about one-third of the lead authors were affiliated with African universities. A majority of the studies were quantitative, and 78% of the studies were done for three countries: Ghana, Morocco, and Nigeria. There was either just one or no study on trust and conflict, partner selection, and human resource management (HRM). At the contextual level, it seems that the most important factor influencing IJV strategy and success is institutions. We therefore suggest a greater use of institutional theory. Finally, we present a summary conceptual framework and four propositions to guide future research.©2021 Wiley. This is the peer reviewed version of the following article: Oguji, N., Degbey, W.

Level of Awareness of Effects of the Use of Cosmetic Bleaching Products among Women: A Case Study of Bolgatanga Municipality of Ghana
This study intends to find out the level of awareness of the harmful effects of cosmetic bleaching products among women in Bolgatanga municipality of Ghana. The study also investigated the motives for skin bleaching as well as observing any physical manifestation of bleaching effects on the skin. Structured questionnaire was the main instrument used for the data collection. The questionnaires were administered in ten (10) selected communities in the Bolgatanga Municipality from which one hundred and twenty (120) women were randomly selected. The results showed that 39.2% of the women interviewed used cosmetics bleaching products, 9 women representing 7.5% experienced related side-effects and 82.4% had no knowledge on the side effects of these bleaching products. Chi-square analysis showed that lack of formal education could account for their ignorance. High amount of sunshine in addition to skin bleaching could serve as a predisposing factor which would lead to the contraction of skin cancer. The knowledge of the effects of cosmetic bleaching products is an imperative measure in maintaining a healthy skin. Keywords: women, cosmetics, bleaching products, skin
Household Economics of Cocoa Agroforestry:Costs and Benefits
Current research suggests that cocoa agroforestry systems could offer stable yields, additional benefits and income from shade trees, despite potential added costs, such as from the purchase of insecticides. There is a paucity of profitability studies of different cocoa agroforestry systems. Only few of them go beyond a narrow focus on cocoa yields to model the entire agroforestry system and thus do not advance our understanding of the socio-economic value of other ecosystem goods. Based on survey data covering a thousand cocoa plots and group interviews with cocoa farmers, we explore the costs and benefits at the household level of including trees in cocoa systems. Comparing low and medium tree diversity systems, we find that income from cocoa beans, timber and fruit trees are higher and labour costs are lower in plots with medium diversity, while insecticide costs are lower on low-diversity plots. Overall, net benefits were higher on cocoa plots with higher tree diversity. Thus, cocoa agroforestry systems offer cost-reduction and income-improving advantages. Since cocoa systems vary among different agro-ecological zones in Ghana, we recommend that interventions aimed at increasing tree diversity consider the specific management practices of each farming household and the location in question
Case study of a method of development of a selection process for community health workers in sub-Saharan Africa
Background
Choosing who should be recruited as a community health worker (CHW) is an important task, for their future performance partly depends on their ability to learn the required knowledge and skills, and their personal attributes. Developing a fair and effective selection process for CHWs is a challenging task, and reports of attempts to do so are rare. This paper describes a five-stage process of development and initial testing of a CHW selection process in two CHW programmes, one in Malawi and one in Ghana, highlighting the lessons learned at each stage and offering recommendations to other CHW programme providers seeking to develop their own selection processes.
Case presentation
The five stages of selection process development were as follows: (1) review an existing selection process, (2) conduct a job analysis, (3) elicit stakeholder opinions, (4) co-design the selection process and (5) test the selection process. Good practice in selection process development from the human resource literature and the principles of co-design were considered throughout. Validity, reliability, fairness, acceptability and feasibility—the determinants of selection process utility—were considered as appropriate during stages 1 to 4 and used to guide the testing in stage 5. The selection methods used by each local team were a written test and a short interview.
Conclusions
Working with stakeholders, including CHWs, helped to ensure the acceptability of the selection processes developed. Expectations of intensiveness—in particular the number of interviewers—needed to be managed as resources for selection are limited, and CHWs reported that any form of interview may be stressful. Testing highlighted the importance of piloting with CHWs to ensure clarity of wording of questions, interviewer training to maximise inter-rater reliability and the provision of guidance to applicants in advance of any selection events. Trade-offs between the different components of selection process utility are also likely to be required. Further refinements and evaluation of predictive validity (i.e. a sixth stage of development) would be recommended before roll-out

Housing attributes and relative house prices in Ghana
Purpose
The study of house prices has become more relevant in recent times after the global financial crisis. Using a housing data set from three regions of Ghana (collated from real estate agents), the purpose of this paper is to estimate the relative importance of housing attributes to house prices.
Design/methodology/approach
The hedonic regression analysis conducted indicates that location is the most powerful determinant of house prices. Other relevant factors are the number of bedrooms, the number of floors, the total floor area, land size, age of the house and luxury finishing.
Findings
The implications of these results are many. Policy wise, the study provides an evidence-based empirical study that supports the need for better urban planning to improve communities, which in turn is associated with house price appreciations. Homeowners, investors and creditors, particularly mortgage lenders could be the immediate beneficiaries. Drawing on this, improved urban planning could mitigate strategic defaults that results from house prices falling below mortgage loan balances. This is important for financial market stability.
Originality/value
The paper provides a comprehensive and unique understanding of the hedonic determinants of house prices in Ghana. Future studies could examine the effect of location upon mortgage lending in Ghana
Profile and outcomes of hospitalized patients with COVID-19 at a tertiary institution hospital in Ghana
Background: In high-income countries, mortality related to hospitalized patients with the Coronavirus disease 2019 (COVID-19) is approximately 4-5%. However, data on COVID-19 admissions from sub-Saharan Africa are scanty.Objective: To describe the clinical profile and determinants of outcomes of patients with confirmed COVID-19 admitted at a hospital in Ghana.Methods: A prospective study involving 25 patients with real time polymerase chain reaction confirmed COVID-19 admitted to the treatment centre of the University Hospital, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana from 1st June to 27th July, 2020. They were managed and followed up for outcomes. Data were analysed descriptively, and predictors of mortality assessed using a multivariate logistic regression modelling.Results: The mean age of the patients was 59.3 ± 20.6 years, and 14 (56%) were males. The main symptoms at presentation were breathlessness (68%) followed by fever (56%). The cases were categorized as mild (6), moderate (6), severe (10) and critical (3). Hypertension was the commonest comorbidity present in 72% of patients. Medications used in patient management included dexamethasone (68%), azithromycin (96%), and hydroxychloroquine (4%). Five of 25 cases died (Case fatality ratio 20%). Increasing age and high systolic blood pressure were associated with mortality.Conclusion: Case fatality in this sample of hospitalized COVID-19 patients was high. Thorough clinical assessment, severity stratification, aggressive management of underlying co-morbidities and standardized protocols incountry might improve outcomes
Antioxidant, Anticancer and Antibacterial Activity of Withania somnifera Aqueous Root Extract
Aims: To evaluate total antioxidant capacity, anticancer activity and antibacterial effects Withania somnifera aqueous-root extracts.
Study Design: In vitro study.
Place of Study: School of Biomedical Sciences, Ulster University, UK.
Methodology: Total antioxidant capacity (TAC) of whole powder and freeze dried W. somnifera aqueous-root extracts was determined using FRAP, DPPH, Folin and ABTS assays. Anticancer activity was accessed using MDA-MB-231 breast cells and Sulforhodamine B staining for cell viability. Antibacterial activity was by disk diffusion assay with penicillin, amoxicillin and streptomycin as positive controls.
Results: The TAC for W. somnifera extract was 86, 47, 195,or 443 gallic acid equivalents per 100g dry basis (mgGAE/ 100 g) using FRAP, DPPH, Folin or ABTS assays, respectively. Corresponding TAC values for freeze dried W. somnifera aqueous-root extract were, 418, 553, 1898 or, 1770 (mgGAE/100 g). W. somnifera aqueous-root extract inhibited MDA-MB-231 cell proliferation in a dose-dependent manner with IC50 = 0.19 mg/ml (21 µM GAE). Nil antibacterial effects were detected for freeze dried W. somnifera extract (0-1 mg/ml) across six species of bacteria tested.
Conclusion: Withania somnifera root water extract showed significant antioxidant and anticancer activity for MDA-MB-231 breast cancer cells but no antibacterial activity under the conditions of this study
