Africa's population is growing at a faster pace, and the growth in megacities and rate of urbanization has been very rapid. Alongside, economic growth is expected to be very robust in the future. Altogether, these will pose serious challenges for the energy system in Africa; a condition that makes the development of renewables (RES) a necessity in the continent. Though the continent is well-endowed with RES, it is least developed and deployed, partly due to limited research and development in the sector. Particularly, the macroeconomic implications of RES have not been thoroughly studied in the continent, which leaves a big literature gap for the continent. This motivates the current study to investigate into the macroeconomic implications of RES using Ghana as the case study, a country that is well-endowed with RES and one of the few in the continent that has integrated RES into their overall energy policy. Specifically, in this study, we examined the implications of RES concentration on electricity price uncertainty. Further, we investigated the persistent profile effect of both system-wide and individual shocks on the equilibrium relations. Finally, we decomposed the variance in electricity price into permanent and transitory components and explained what drives these trends. © 2017 Elsevier Ltd

Purpose: Corporate social responsibility (CSR) communication on corporate websites have become an emerging trend by firms. Similarly, corporate websites have been used to manage stakeholders’ impressions about the organization. Meanwhile, CSR by firms have been criticized for been a manipulative tactics used by firms. The purpose of this paper therefore is to ascertain how telecommunication companies operating in Ghana communicate CSR on their corporate websites. Design/methodology/approach: This study used a qualitative content analysis technique. It also used Bolino et al.’s (2008) impression management framework as the conceptual framework. Data were extracted from the websites of four telecommunication companies operating in Ghana. Data were analyzed using thematic analysis techniques. Findings: The results show that the companies use impression management in communicating CSR on their corporate websites. Account, assertive impression management; blaring, boasting, defensive impression management; demonstrative impression management; exemplification, favor-rendering, illustrative impression management; ingratiation, other-enhancement, other-focused impression management; self-enhancement, self-focused impression management; and self-promotion tactics are tactics prevalent in the CSR communication of the companies. Actor-to-actor link impression management and other emotional appeal also emerged as some of the impression management tactics used by the companies. Originality/value: This provides insights into how organizations use impression management in their CSR communication on their corporate websites. Studies of this nature are limited. Again, studies specifically adapting Bolino et al.’s impression management to study CSR communication on corporate websites are rare. © 2017, © Emerald Publishing Limited.

This study examined the effects of changing trade structure and changing technical characteristics of the manufacturing sector alongside the effects of foreign direct investment and urbanization on energy intensity in Ghana. In order to produce a result that is not biased towards non-rejection, the Zivot-Andrews unit root test with structural break was used. The study applied the Phillip-Hansen, Park, and Stock-Watson cointegration models, which are more robust to serial correlation and exogeneity problems. Preliminary findings showed evidence of cointegration. The study concludes that the changing technical characteristics of the manufacturing sector after the reform and changing production mix in favor of less energy intensive improved energy efficiency. However, energy consumption via exports which outweighed the energy saving via imports of capital goods after the reform in 1983 worsened energy efficiency. Growing urbanization significantly increases energy intensity. In all, technological diffusion via trade exerts significant influence on energy intensity than technological diffusion via foreign direct investment. These results are robust to the Cholesky variance decomposition analysis. © 2014 Elsevier Ltd.

One of the most pressing problems of the post genomic era is identifying protein functions. Clustering Protein-Protein-Interaction networks is a systems biological approach to this problem. Traditional Graph Clustering Methods are crisp, and allow only membership of each node in at most one cluster. However, most real world networks contain overlapping clusters. Recently the need for scalable, accurate and efficient overlapping graph clustering methods has been recognized and various soft (overlapping) graph clustering methods have been proposed. In this paper, an efficient, novel, and fast overlapping clustering method is proposed based on purifying and filtering the coupling matrix (PFC). PFC is tested on PPI networks. The experimental results show that PFC method outperforms many existing methods by a few orders of magnitude in terms of average statistical (hypergeometrical) confidence regarding biological enrichment of the identified clusters. © Springer International Publishing Switzerland 2016.

I use a two-state (energy efficient/inefficient) Markov-switching dynamic model to study energy efficiency in Cameroon in a novel manner, employing yearly data covering 1971 to 2012. I find that the duration of an energy inefficient state is about twice as long as an energy efficient state, mainly due to fuel subsidies, low income, high corruption, regulatory inefficiencies, poorly developed infrastructure and undeveloped markets. To escape from an energy inefficient state a broad policy overhaul is needed. Trade liberalization and related growth policies together with the removal of fuel subsidies are useful, but insufficient policy measures; the results suggest that they should be combined with structural policies, aiming at institutional structure and investment in infrastructure. © 2015 Elsevier B.V..

This study analysed the problem of energy intensity determinants in Nigeria based on the fully modified OLS and canonical cointegration regressions. These methods were preferred since they are able to deal effectively with the second-order bias problems, an often characteristics of time series data. The impacts of price of crude oil, FDI, trade openness and industry structure are asymmetric which suggests the presence of structural effects in parameters. The impact of crude oil price is negative but becomes stronger post-1989 saving .126% more in energy consumption relative to pre-1989. Also, the impacts of FDI and trade openness are negative and significant but become stronger post-1989 saving 11.2% and 0.8% more in energy consumption relative to the baseline, respectively for every one percentage point increase in FDI and trade openness. The impact of industry value-added is positive and significant but weakens after 1989 consuming 1.8% less in energy for every one percentage point increase in industry value-added relative to the baseline. The energy reducing effect of industry value-added post-1989 reflects improvements in the technical characteristics of industrial sector in Nigeria. Last, the result showed that the absorptive capability and industry characteristics of Nigeria are important determinants of how FDI affects energy intensity. This implies that a more integrated FDI programme (considering the country characteristics) rather than a 'one-fit-all' programme is preferable. © 2015 Elsevier B.V.

Analysis of the unconditional impacts of foreign direct inflows (FDIs) and industrialization on energy intensity does not show the hidden roles of some economic conditions such as income and trade openness. In this study, we focused on the conditional impacts of FDIs and industrialization on energy productivity using a panel data consisting of thirteen (13) East African countries covering 1980–2011. The baseline result shows that higher income and a well-integrated economy are pro-energy productive, but FDIs and intense industrialization are anti-energy productive in the sub-region. This result remains robust even when we exclude the high income group and control for income group effects. Income significantly promotes energy productivity more in low income group than middle income group. Intense industrialization and FDIs significantly decreases energy productivity only in low income countries. Trade openness significantly promotes energy productivity only in middle income group. We have shown that FDIs and income, intense industrialization and FDIs, and intense industrialization and globalization are complementary forces that promote energy productivity in East Africa but this is more evident for the middle income group than the low income group in the sub-region. Based on the result, we recommend a quadruplet programme called the “Growth, Industrial, Foreign investment and Trade programme” (GIFTP). Last, our result suggests that unconditional analysis of energy productivity should not be seen as an end in itself but a basis for further analysis. © 2016 Elsevier Ltd

Despite the prevalence of voluntary and involuntary energy conservation policies, developing countries in Africa continue to struggle to achieve energy efficiency targets. Consequently, energy intensity levels have risen threatening the security of the energy system. This raises the important question: is there an economic state that induces agents to be energy conscious? In this study, we study the case of Algeria's energy intensity from 1971 to 2010. First, the paper argues that there is a certain economic state that economic agents find investing in energy conservation a viable option. Any state different from that would mean not investing in energy conservation. Second, the paper argues that the economy can do better even with an infinitesimal reduction in fuel subsidy, and that the gains in revenue from the policy can compensate for the negative socio-economic and equity impacts associated with such a policy. Third, the paper argues that, so long as, industrial expansion in the country move parallel with investment in technological innovation, long-term sustainable growth and energy conservation targets are jointly feasible. Fourth, the paper shows that income elasticity evolves with the business cycle, and the absorptive capability of the host country affects how FDI (foreign direct inflows) impact energy intensity. © 2015 Elsevier Ltd.

Aim: Increase understanding of nursing leadership in group clinical supervision (CS). Background: Leadership in CS has received little interest besides the theories in use and administrative CS. Method: Hermeneutic interpretation of written narratives of 24 clinical nurse supervisors. Results: Continuity in structuring, story and mission and reflection in group and leadership processes and theories of nursing and caring characterize leadership in CS. Leadership by inhibiting and creating fear, inapproachability and indistinctiveness were patterns in content brought to CS. Supervision when leadership was involved illuminated a reflexive change in focus from leadership to nursing care, from particular experiences to nursing and caring science, and from the unfamiliar to the well known and the well known to the unknown. Conclusions: Continuity and reflective changes using nursing and caring theories seem to be core ideas of nursing leadership from the perspective of CS. The poles of separation and communion show opposites of nursing leadership as it is illuminated in CS. The findings add knowledge to Bondas' theory of caritative leadership. Implications for nursing management: CS is a reflexive practice of support and guidance that seems to have an impact on the trajectory of nursing care and staff development using nursing and caring theories. © 2010 The Author.

The aim of this study is to explore and describe a patient perspective in research on intercultural caring in maternity care. In total, 40 studies are synthesized using Noblit and Hare's meta-ethnography method. The following opposite metaphors were found: caring versus non-caring; language and communication problems versus information and choice; access to medical and technological care versus incompetence; acculturation: preserving the original culture versus adapting to a new culture; professional caring relationship versus family and community involvement; caring is important for well-being and health versus conflicts cause interrupted care; vulnerable women with painful memories versus racism. Alice in Wonderland emerged as an overarching metaphor to describe intercultural caring in maternity care. Furthermore, intercultural caring is seen in different dimensions of uniqueness, context, culture, and universality. There are specific cultural and maternity care features in intercultural caring. There is an inner core of caring consisting of respect, presence, and listening as well as external factors such as economy and organization that impact on intercultural caring. Moreover, legal status of the patient, as well as power relationships and racism, influences intercultural caring. Further meta-syntheses about well-documented intercultural phenomena and ethnic groups, as well as empirical studies about current phenomena, are suggested. © 2010 A. Wikberg & T. Bondas.
