This culture has not yet been fully developed, although companies such as, Nestle, Unilever, McDonalds etc are making the effort. This review revisits the evolution of human resource management in multinational firms especially in Sub-Saharan Africa and the progress towards the building up of a diversified workforce. It explores the phases of diversity in these multinational organizations and measures adopted to overcome these challenges. The review ends with an overview of the prospects of diversity management for the future growth of these multinational.

Yet an emerging theme in contemporary research provides support for the integration of Prediction Markets within public and private hospitals to reduce costs and free up valuable resources, ultimately bettering quality of life and service. Our study compared the post sample prediction error of an enhanced prediction market tool and exponential smoothing to predict patient arrivals in selected departments in a hospital in China. The prediction market estimates provide a more accurate forecast on two-of-three occasions compared to exponential smoothing model in all the three departments under consideration. Despite the range of experience both in the field of work and the hospital itself, no correlation was found between experience in either and the accuracy of estimates within each of the three units. Similar to the experience, the age variables is also highly insignificant in correlation with estimate accuracy

This is because most healthcare facilities are managed by medical officers with significant bias towards exporting their clinical experiences to medical forecasting and decision making for all aspects of healthcare including patient flow, bed allocation, transport scheduling, staff scheduling, supply chain management, menu services. We investigated the extent to which experiences of healthcare professionals can be harnessed and optimized for evidential use as a swarm intelligence technique. A demand forecasting scenario was modeled based on data collected from healthcare facilities in China. The data was simultaneously modeled using artificial neural networks and prediction market. The prediction market and artificial neural network models were equally competitive with no statistical difference in mean average percentage error. Both of them outperformed the unweighted linear average method.

The need to consolidate and support women to procreate in tranquillity has inspired international and domestic agencies to harness the resources at their disposal to protect the health of women especially during pregnancy, child birth and the post-partum period. Methods The study applied a systems dynamic model to selected data to establish the influence of the universal two-child policy in China on maternity insurance fund income. The study also established sensitivity analysis of the appropriate rate of contribution to keep the fund active. Results The study revealed that increases in utilisation rate as results of increase in number of births under the universal two-child policy increased the accumulated deficit of the matern...

Yet, the benefits of e-procurement are monumental and multifaceted. The objective of this study is to investigate the barriers of Ghanaian hospitals on e-procurement adoption decision. The current state of E-procurement in hospitals has been studied very little, yet hospitals play an important role in the global supply chain management. A questionnaire was administered to senior members with significant influence on hospital procurement in ten regional hospitals in Ghana. This was augmented by evidence from officials of the Public Procurement Authority and senior staff of the Ministry of Health and Ghana Health Service. We constructed and used a more sophisticated structural equation model (SEM) to analyze the relationship between E-procurement barriers and E-procurement adoption and possible mediating an...

The turn of the millennium has seen a surge in related studies and the controversies surrounding the need to delegate responsibilities, the degree of authority appropriate to execute a delegated responsibility and other consequences thereof. The tragedy of the spate of suicide s linked to employee right abuses at the "Foxconn City" industrial park in Shenzhen , China gained global momentum in 2010. The accompanying global condemnation of an institution whose customers included Apple and Hewlett Packard was expected to set a context for a new bi-directional human resource management paradigm that significantly accounts for morality. Yet, nearly a decade after the global response, there are still multiple reports of labour right issues in different parts of China despite central government’s extended resolve to control any such exc...

Systemic determination of the relationship is because of observations over a period. It is, however, possible to analyze this relation from a system present from the word-go. This then allows for the interaction to be analyzed on the basis of performance and logically gains for participation by all the agents. Several models have been proposed to deduce the Triple Helix Relation and these hold. This paper has however introduced a new dimension to the analysis, by viewing participation from an investor point of view with decision making being of a complex and deductive nature based on the performance of higher education systems or institutions. The TOPSIS supported performance deductions helps synthesis decision solutions that facilitates value determination of performance and its resultant impact on investment gains. Possible future im...

This initiative was pioneered by business managers and owners to know more about the potency of the internet including how it supports payments from one place to the other. Today there are many micropayment system used on various internet platforms but all of these developed from the ground breaking effort of the first generation of internet micropayment systems most of which have died a natural death. We examine in this paper, the development trend of e-commerce payment platforms; starting from the evolution of the NetBill. Subsequently, we evaluate the competitive environment within which the first generation of micropayment systems operated and their eventual waterloo. After exploring the challenges and failures of the first generation of ecommerce payment systems, we aggregate and d...

A proposed unified information technology acceptance research model called Unified Theory of Acceptance and Use of Technology (UTAUT) was used. The model integrates significant elements across eight prominent user acceptance models and formulates a unique measure with core determinants of user behavioural intention and usage. This paper presents findings of a study that validates the UTAUT model in the subject of the user acceptance towards an educational technology. In this study, a total of 262 respondents from two medical schools in Ghana were surveyed for their acceptance of e-learning technologies. The results of the study provide an explorator...

However, within the past decade, conflicting evidence of the generalisability of crowd wisdom techniques in forecasting has reignited the debate on their robusticity in healthcare decision making. Patient arrivals at emergency departments of selected hospitals in China were modelled and predicted using a prediction market crowd wisdom technique. The mean average percentage error was compared with similar predictions using the seasonal autoregressive integrated moving averages. The prediction market quarterly patient flow prediction defeated the seasonal autoregressive moving averages model by 0.06% in the affiliated hospital of the Guilin medical university and by 0.56% in the affiliated Jiangsu university hospital but were weaker in terms of daily and monthly predictions. Moreover...

Aware of the relative weight and significance of the supply chain, many hospitals in Ghana have initiated measures to fully adopt technology towards the performance of key healthcare activities. Using data collected from selected public hospitals in the Ashanti Region of Ghana, we recalibrate and classify the influential or stimulating factors of e-procurement adoption into exogenous and endogenous variables to determine the most influential factor. We employ a more sophisticated co-integration approach in order to observe robustness of outcome relative to the extant models. We observed that e-procurement optimization is premised on the prevalence of an ensemble of exogenous and endogenous factors including resources availability, facilitating conditions, system interoperability, supplier compatibility, regulatory framework, operational standards and benchmarks and other external/industry factors.

These notwithstanding many institutions in developing countries are facing tremendous challenges in leveraging the benefits of e-procurement. This paper reviews current literature on e-procurement system. It focuses on existing models and framework for the adoption of e-procurement in the healthcare sector. Typically, the paper reviews the current procurement practices in the related literature, concepts of other studies conducted with respect to the overall supply chain enhancement and value chain efficiency practices. Based on an evaluation of these concepts, a model framework is proposed for public hospitals in Ghana towards effective deployment, acceptance and use of e-procurement to accentuate healthcare value creation and customer satisfaction

But such blanket opposition ignores valid reasons for not dismissing the value markets could bring. Since its inception in 1948 the NHS in England has gradually evolved (and devolved) into a very different being. No longer is it – in the words of health policy analyst Rudolf Klein the ‘secular church’, maintained and presided over by disciples of its founder, Aneurin Bevan. In its current state, the NHS functions on the basis of what has been variously called a ‘quasi’, ‘mimic’ or ‘internal’ market with its own risk levels for investors. For risk managers, at the centre of strong risk management is suitable risk metrics that are constructed using complex mathematical models. This study looks at the three approaches and how they apply in computing VaR. For the three techniques, VaR is defined and the main methodologies. Thereafter, the m...

The importance of pension reforms is credited to its potential to guarantee a sustainable pension scheme that provides with a decent life to pensioners and their dependents. This research gives a detailed analysis on pension reform theories such as economic theory, multi-pillar model by the World Bank, theory of utility and preferences and life cycle theories. It further discusses the three retirement decision models: two-thirds retirement decision model, the option value retirement decision model and one-year retirement decision model used in explaining various decisions relating to retirement and also the forms of retirement benefits payments. Finally, it discusses the four approaches by which pension reforms can be analyzed. Key words: pension reform, retirem...

This study, therefore, evaluates how human activities such as urbanization, farming and industrialization affect the Bonsa River and the health-related quality of life of residents living downstream. The study adopted statistical package for the social sciences (SPSS) and partial least square structural equation modeling (PLS-SEM) to assess the data retrieved from the residents living in and around the Bonsa River in Tarkwa Nsuaem, Ghana. The study’s outcome reveals a positive and significant impact of land use change on freshwater resource degradation and poor health-related quality of life of the inhabitants in the catchment area. The study has numerous practical and policy implications for the government, environmental and healthcare industry, and policymakers.

It constructed the theoretical framework of the health vulnerability of rural-to-urban elderly migrants. The health status of rural-to-urban elderly migrants was divided into three dimensions: physical health, mental health, and social adaptation. A total of 658 rural-to-urban elderly migrants in 12 cities of Jiangsu province were selected as samples for empirical test and analyzed the influence of individual endowments and social welfare on the health status of rural-to-urban elderly migrants and their differences. The result shows that personal ability affects the social adaptation ability of rural-to-urban elderly migrants, and social welfare has a significant influence on the physical and mental health of rural-to-urban elderly migrants. Lacking the learning ability of rural-to-urban elderly migrants in sample areas is the main fa...

This need to rejuvenate urban water management in developing countries such as Ghana through effective innovation strategies has renewed academic interest in traditional models of innovation diffusion. Our study sought to investigate the influence of complex adaptive system in adopting technology innovation in urban water delivery system. We augmented Rogers‘ innovation diffusion configuration with three complex adaptive system parameters to overcome the linearity assumption of the former. 195 questionnaires were administered to purposively sampled participants who work in different areas of Ghana‘s urban water supply system. We observed that incorporating complex adaptive system network parameters improved innovation diffusion by 10 percentage points (reduces the prediction error from 17% to 13%). Our study supports the school of thought that innovation diffusion is not a linear process. The complexity requires the adoption of complex adaptive systems to accentuate its acceptance in an organization.

The emergence of artificial neural networks and prediction markets as swarm intelligence tools has significantly improved medical forecasting in many fronts. Till date the main clinical use of artificial neural networks and prediction markets includes diagnosis, prognosis, disease severity testing and scoring, and measuring the spread of diseases and many other areas of applications yet not many studies have emerged from Jiangsu Province in China. We modeled and compared the historical records and doctor’s evaluation summary of a cohort of 150 patients diagnosed and operated on gastric cancer in general practice using an enhanced prediction market, Cox hazard proportion and artificial neural network. We conclude that prediction market techniques can complement artificial neural networks and Cox hazard regression models in prognosis
