Assessment of citrus diversity in Ghana

Citrus is among the plant germplasm conserved at the CSIR - Plant Genetic Resources Research Institute (CSIR - PGRRI), Bunso in Ghana; however, due to lack of information on the specific traits of this germplasm at the Institute, the potential diversity within the collection is not yet fully exploited. The objective of this study was to evaluate the morphological diversity among the citrus accessions under conservation at the field genebank of the CSIR - PGRRI, Bunso, Eastern region of Ghana. The various accessions were raised on rough lemon rootstocks, planted using the augmented design. The citrus accessions evaluated include different citrus types suitable for different purposes, such as Flying Dragon for rootstock, Sweet Lime for medicine and Mediterranean Sweet for fruit drink. Late Valencia and Mediterranean Sweet were used as checks. Planting was done at 8 m by 8 m. Apart from watering immediately after planting, the plants grew under natural condition without irrigation. Variability was revealed by all the traits studied, including scion trunk surface, tree shape, tree growth habit and branch angle, based on IPGRI descriptors for citrus. The resulting phylogenic tree clustered the citrus accessions mainly based on known genetic relationships, using the clustering away of citrons from mandarins as an example. Although the morphological traits used in the characterisation were not sophisticated, they were useful in discriminating among the accessions. Based on this study, the citrus genebank at CSIR - PGRRI, Bunso, Eastern region of Ghana contains 44 morphologically distinct accessions. The information generated in this study is important for guiding conservation and utilisation decisions geared towards the improvement of the citrus sub-sector in the country

As such, there is an ongoing effort to accurately quantify the thermal performance of shading devices. In the present study, solar gain through various shading devices attached to a conventional double glazed window was measured using the National Solar Test Facility (NSTF) solar simulator and solar calorimeter. The shading devices include two venetian blinds, a roller blind, a pleated drape and an insect screen. More specifically, the solar heat gain coefficient (SHGC) and the solar transmittance, tsys, of each system were measured; and the interior attenuation coefficient (IAC) was calculated from the SHGC measurements. Furthermore, SHGC, tsys and IAC were calculated for the same experimental conditions using models developed for building energy simulation and performance rating. The calculations agreed very well with the measurements.NRCan (Natural Resources Canada) || NSERC (Natural Scienes and Engineering Research Council Canada) || ASHRA

Fungi associated with sweet potato tuber rot at CSIR - PGRRI, Bunso, Eastern Region, Ghana

Rotten sweet potato root tuber samples were collected from a barn and experimental field of the CSIR - Plant Genetic Resources Research Institute (PGRRI), Bunso. Isolation and identification of the fungi associated with the samples were carried out at the Plant Pathology Laboratory of the same institute. In all, six fungal species belonging to four genera, namely Fusarium solani, Sclerotium rolfsii, Lasiodiplodia theobromae, Aspergillus ochraceus, Aspergillus flavus and Aspergillus niger were isolated from the samples from both the barn and the experimental field of CSIR - PGRRI. Fusarium solani and Aspergillus niger were frequently isolated from the sweet potato tuber samples from both the field and the barn. Pathogenicity tests carried out using the six fungal isolates on fresh and healthy sweet potato tubers showed that all the six fungi isolated were pathogenic in causing rot of sweet potato tubers with Lasiodiplodia theobromae being the most virulent

The Early Years

Policy concentration on the early years is of vital importance for the wellbeing of children now and for their future health outcomes and life chances. Evidence-based research points to the need for a focus that is properly holistic and to precipitate intervention to promote a healthy diet, regular patterns of activity and rest and give children the best start in life. In 2005, The United Nations Committee on the Rights of the Child (General Comment No. 7) acknowledged the need for a fresh strategy, pinpointing research findings indicating that a failure to prioritise early years’ welfare exposes children to the ills of ‘malnutrition, disease, poverty, neglect, social exclusion and a range of other adversities.’ Professor Dame Sally Davies, Chief Medical Officer of the United Kingdom, considers that robust early years’ policies make both social and economic sense: ‘Too many children and young people do not have the start in life they need, leading to high costs for society, and too many affected lives’ (Forward to ‘The 1001 Critical Days’, June 16th 2014). This observation is significant because there remains much to do. In 2012, the NSPCC reviewed the United Kingdom policy scenario for babies and very young children and concluded that identifiable advances in maternity and early years’ provision did not detract from the fact that: ‘babies are still particularly vulnerable’ and ‘their rights are not always recognised or realised’. (‘All Babies Count – But what about their rights?’ Sally Knock and Lorriann Robinson, January 2012). Knock and Robinson highlight glaring gaps of support and provision – especially in maternity services whereby the fostering of a strong parent-child bond is invariably sacrificed to a concentration upon purely medical practicalities such as labour, birth and the immunisation programme. The All Party Group on a Fit and Healthy Childhood aims, in this report, to offer the incoming Government recommendations for an early years’ strategy that are credible, feasible and evidence-based and will enable the United Kingdom to set the standard in a crucial policy field both at home and abroad. In defining ‘early childhood’, we follow the example of The United Nations (2005) Convention on the Right of the Child by examining the period of 0-8 including, as it does, the vital transition phase from pre-school to primary school. We consider the antenatal period and maternal physical and mental health, methods of feeding the newborn, parental support services both hospital and home-based and infant nutrition and socioeconomic factors that may impact upon the health and wellbeing of young children. The report examines the optimum balance between sleep, rest and activity, the need for freely-chosen play, safeguarding measures and the importance of respecting cultural diversity in all early years’ settings. Above all, we analyse the relationship between young families and the professionals whose role it is to ensure that babies have the very best start in life, supported by parents who have confidence in the choices that they make and the advice that they are given. Just as new families require mentoring so that they can act in the best interests of their children, so the early years’ workforce needs training and continuous professional development to ensure that the advice given is of the highest possible quality and specifically tailored to the individual family. Early Years’ students from The University of Northampton (interviewed) explain what a positive difference their newly acquired knowledge has made to their performance in the settings and Government recognition of The Early Years as a developmental stage in its own right and the creation of the new posts of Early Years Teacher and Early Years Educator have been positive. Yet as the Ilkeston ‘Mums Group’ (interviewed) makes clear, there is still no guarantee of uniform excellence in the delivery of services nationwide and no assurance of continuity between, for example, advice on feeding from the midwife and the health visitor, or the emphasis put on freely-chosen play in an early years’ setting and a primary school. If young children are to thrive, we believe it is essential that there is a national consensus and political will behind multi-disciplinary working in the early years. We see the early years as a window of opportunity and make no apology for the fact that each section of this report is accompanied by many policy recommendations. It has not been possible to produce a uniform handful of ‘asks’, just as the early years itself is a rich, complex and multifarious developmental phase. However, neither do we consider it to be feasible to achieve everything that we recommend in the lifespan of a single Government. This is a two, even three term journey. However, if the nation’s families and the early years workforce are to embark upon it, the Government must be prepared to provide the resources; the Cabinet Minister for Children and Families, the commitment to multi-disciplinary co-operation to achieve an early years workforce that is truly ‘joined up’ and, above all, the finance to make well–intentioned aspiration a reality. In an age of austerity, by spending early, the later savings to education, health, social or criminal justice services will be immense. Investing in the children of today is not a gambl

The short term debt vs. long term debt puzzle: a model for the optimal mix

This paper argues that the existing finance literature is inadequate with respect to its coverage of capital structure of small and medium sized enterprises (SMEs). In particular it is argued that the cost of equity (being both conceptually ill defined and empirically non quantifiable) is not applicable to the capital structure decisions for a large proportion of SMEs and the optimal capital structure depends only on the mix of short and long term debt. The paper then presents a model, developed by practitioners for optimising the debt mix and demonstrates its practical application using an Italian firm's debt structure as a case study

Doing Business and Inclusive Human Development in Sub-Saharan Africa

Purpose- This study examines how doing business affects inclusive human development in 48 sub-Saharan Africa for the period 2000-2012. Design/methodology/approach- The measurement of inclusive human development encompasses both absolute pro-poor and relative pro-poor concepts of inclusive development. Three doing business variables are used, namely: the number of start-up procedures required to register a business; time required to start a business; and time to prepare and pay taxes. The empirical evidence is based on Fixed Effects and Generalised Method of Moments regressions. Findings- The findings show that increasing constraints to the doing of business have a negative effect on inclusive human development. Originality/value- The study is timely and very relevant to the post-2015 Sustainable Development agenda for two fundamental reasons: (i) Exclusive development is a critical policy syndrome in Africa because about 50% of countries in the continent did not attain the MDG extreme poverty target despite enjoying more than two decades of growth resurgence. (ii) Growth in Africa is primarily driven by large extractive industries and with the population of the continent expected to double in about 30 years, scholarship on entrepreneurship for inclusive development is very welcome. This is essentially because studies have shown that the increase in unemployment (resulting from the underlying demographic change) would be accommodated by the private sector, not the public sector

Basic Formal Education Quality, Information Technology and Inclusive Human Development in Sub-Saharan Africa

This study assesses the relevance of basic formal education in information technology for inclusive human development in 49 countries in sub-Saharan Africa for the period 2000-2012. The question it aims to answer is the following: what is the relevance of basic formal education in the effect of mobile phone penetration on inclusive human development in sub-Saharan Africa when initial levels of inclusive human development are taken into account? The empirical evidence is based on instrumental quantile regressions. Poor primary education dampens the positive effect of mobile phone penetration on inclusive human development. This main finding should be understood in the perspective that, the education quality indicator represents a policy syndrome because of the way it is computed, notably: the ratio of pupils to teachers. Hence, an increasing ratio indicates decreasing quality of education. It follows that decreasing quality of education dampens the positive effect of mobile phone on inclusive development. This tendency is consistent throughout the conditional distribution of inclusive human development. Policy implications for sustainable development are discussed

Boosting quality education with inclusive human development: empirical evidence from sub-Saharan Africa

This study examines the importance of inclusive human development in promoting education quality in a panel of forty-nine Sub-Saharan African countries for the period 2000-2012. The empirical evidence is based on Ordinary Least Squares (OLS), Fixed Effects (FE) and Quantile Regression (QR) estimations. It is apparent from the OLS and FE findings that inclusive human development has a negative effect on the outcome variable. This negative effect implies that inclusive human development improves education quality. This result should be understood in the light of the fact that the adopted education variable is a negative economic signal given that it is computed as the ratio of pupils to teachers. Therefore, a higher ratio reflects diminishing education quality. From QR, with the exception of the highest quantile, the tendency of inclusive human development in reducing poor quality education is consistent throughout the conditional distribution of poor education quality. Policy implications are discussed

The Comparative Economics of ICT, Environmental Degradation and Inclusive Human Development in Sub-Saharan Africa

This study examines how information and communication technology (ICT) could be employed to dampen the potentially damaging effects of environmental degradation in order to promote inclusive human development in a panel of 44 Sub-Saharan African countries. ICT is captured with internet and mobile phone penetration rates whereas environmental degradation is measured in terms of CO2 emissions per capita and CO2 intensity. The empirical evidence is based on Fixed Effects and Tobit regressions using data from 2000-2012. In order to increase the policy relevance of this study, the dataset is decomposed into fundamental characteristics of inclusive development and environmental degradation based on income levels (Low income versus (vs.) Middle income); legal origins (English Common law vs. French Civil law); religious domination (Christianity vs. Islam); openness to sea (Landlocked vs. Coastal); resource-wealth (Oil-rich vs. Oil-poor) and political stability (Stable vs. Unstable).Baseline findings broadly show that improvement in both of measures of ICT would significantly diminish the possibly harmful effect of CO2 emissions on inclusive human development. When the analysis is extended with the abovementioned fundamental characteristics, we observe that the moderating influence of both our ICT variables on CO2 emissions is higher in the group of English Common law, Middle income and Oil-wealthy countries than in the French Civil law, Low income countries and Oil-poor countries respectively. Theoretical and practical policy implications are discussed
