Cocoa introductions into Ghana

Cocoa breeding and selection programmes in Ghana and other West African countries have been based largely on existing cultivated populations or on few collections of wild cocoa. The most widely used cocoa germplasm derives from the material collected by F. J. Pound during the periods 1937-1938 and 1942-1943 and distributed as the Iquitos Mixed Calabacillos (IMC), Nanay, Parinari, Scavina, and the Pound series of clones. This material collected in the Upper Amazon region has been particularly successful, suggesting that cacao would be greatly improved if more germplasm material were provided for use by breeders. Maintaining adequate genetic variability in cocoa germplasm collection, essential for sustainable cocoa production, can be realised through active and conscious germplasm acquisition. Because there is the risk of accidentally introducing diseases and pests along with cocoa germplasm material, effective indexing procedures, together with the availability of final quarantine houses in individual producing countries, are essential to ensure that introduced materials are free of diseases and pests. To be successful as breeding material for producing improved varieties for farmers, the introductions must have some desirable characteristics acceptable to chocolate manufacturers and farmers.Les programmes de reproduction et de sélection de cacao au Ghana et dans d'autres pays de l'Afrique occidentale ont été fondé en grande partie sur les populations de cultures existantes oú sur un tous petit nombre de collections de cacao sauvage. Le germeplasme de cacao le plus utilisé sur une grande étendue vient de matières ramassées par F. J. Pound en 1937-1938 et en 1942-1943 et distribuées sous les noms d'Iquitos Mixed Calabacillos (IMC), Nanay, Parinari, Scavina et Pound comme des séries de clones. Une succès particulier a été réalisé avec cette matière ramassée de la région de Haute Amazone. Ce succès suggère que même de plus grandes améliorations en cacao pourraient être possible si beaucoup auraient été disponible pour utilisation par les phytogéticiens. Le maintien de variabilité génétique adéquate en collection de germeplasme de cacao est essentiel pour la production durable de cacao et ceci pourrait être réalisé par acquisition active et consciente de germeplasme. Puisqu'il y a le risque d'introduire par hasard les maladies et les insectes nuisibles avec la matière de germeplasme du cacao, les procédures efficaces d'indexation, ainsi que la disponibilité de salles de quarantaine finale dans chaque pay producteur sont essentiel pour assurer que les matietes introduietes sont sans maladies et insectes nuisibles. Pour réussir comme matière de reproduction pour la production de variétés améliorés pour les agriculteurs, les introductions devraient avoir quelques caractéristiques désirables er acceptables aux fabriquants de chocolat et aux agriculteurs.

Variations in the level of resistance to root-knot nematodes (Meloidogyne spp.) infestation among ten cowpeas (Vigna unguiculata L. Walp.) genotypes

The cultivation of cowpea (Vigna unguiculata L. Walp.) cultivars that are tolerant to root-knot nematode attack is among the environmentally safe approach to managing the root-knot nematode menace in cultivated crops. In this study, the tolerance of 10 cowpea genotypes to root-knot nematodes infestation was evaluated in a pot experiment conducted in a Screenhouse, at the University for Development Studies, Nyankpala Campus. The experiment was laid out in a completely randomized design with three replications. The number of second stage juveniles (J2) per 250 cm3 of soil sample were counted while the severity of root-knot nematode damage (root galls) was assessed. The reproduction index (RI) was used to classify the varieties as resistant or susceptible. There was a significant difference (P < 0.05) in the number of second stage juveniles of root-knot nematode (RKN), galling index and RI among the genotypes tested. The study revealed that cowpea genotypes SARI 1-4-90, Padi tuya, Songotra, IT99K-1122, Sanzi and Apagbaala were moderately resistant whereas cowpea genotypes IT86D-610, Zaayura, SARI 5-5-5 and IT07K-299-6 were slightly resistant. Thus, the six moderately resistant cowpea genotypes were suggested to be used as a source of resistance to RKN in future breeding works

Corporate Social Performance and Non-Financial Reporting in the Cruise Industry: Paving the way towards UN Agenda 2030

This article investigates the role of accounting disciplines in assessing and fostering corporate social performance (CSP) of business organisations to meet the UN Agenda 2030. Drawing from legitimacy theory, this qualitative study analyses if and how non-financial reporting positively affects and fosters CSP practices and outcomes within the cruise industry. Specifically, using a case study methodology, a major cruise company has been analysed outlining its sustainable behaviour, through the manual content analysis of sustainability reports (2016–2017–2018), in achieving the sustainable development goals (SDGs) introduced by the UN Agenda 2030. The findings outline that the cruise company presents a clear sustainability and community orientation and adopts several initiatives, mostly focused on environmental and social issues, addressed to meet the 17 SDGs, where reputation and positive image have been recognised as the major antecedents in the perspective of CSP. This study contributes to the literature giving a broader and different reading of sustainability reporting as a “booster” of the CSP in meeting the SDGs and a further interesting application of the legitimacy theory, and offers managerial implications to systematise the content of non-financial reporting by improving the quality of disclosure to achieve the SDGs, with focus on CSP processes, outcomes and ways

Safe use of NSAIDs and RAS-inhibitors at Agogo Presbyterian Hospital, Ghana

Background: Preventable adverse events of medication are an important cause of hospital admissions in the developed world, in which non-steroidal anti-inflammatory drugs (NSAIDs) and renin angiotensin system (RAS-) inhibitors are frequently involved. NSAIDs and RAS-inhibitors are also often used in Ghana. The purpose of this study is to assess whether biochemical monitoring in patients on RAS inhibitors, and co-administration of gastro protective agents (GPAs) in patients on NSAIDs, is done properly in Ghana.Material and methods: Two retrospective cross-sectional studies were carried out at the Agogo Presbyterian Hospital, Ghana, in 2013. In 114 out-and inpatients who are on NSAIDs, the risk for gastrointestinal side effects and the frequency of co-administration of GPAs were determined. In 301 outpatients who are on RAS-inhibitors, the risk for renal dysfunction and the frequency of biochemical monitoring were determined. Fisher’s exact test was used to determine the statistical strength.Results: Co-administration of GPAs was done in 1.8% of patients on NSAIDs. Serum creatinine and potassium monitoring within one month after initiation of treatment with RAS-inhibitors were performed in 6.3% and 3.7%, respectively. Risk factors were neither associated with prescription of a GPA in patients on NSAIDs (p=0.134), nor in performing biochemical monitoring in patients on RAS-inhibitors (p=0.219 for creatinine, p=0.062 for potassium).Conclusions: Biochemical monitoring in patients on RAS-inhibitors and use of GPAs in patients on NSAIDs is poorly performed at the Agogo Presbyterian Hospital in Ghana. Improving the already existing Ghanaian guidelines, especially those for RAS-inhibitors, and encouraging their widespread use among prescribers should be pursued.Keywords: Ghana, Non-Steroidal Anti-Inflammatory Agents, Anti-Ulcer Agents, Angiotensin-Converting Enzyme Inhibitors, Angiotensin Receptor Antagonists, Drug monitorin

The health and social care costs of a selection of health conditions and multi-morbidities

Background Multimorbidity (MM) is the presence of 2 or more long-term health conditions in a single individual. It impacts an individual’s quality of life, mental health and wellbeing, daily function, and often results in greater healthcare utilisation the more co-existing conditions they have (1-4). MM is a big challenge facing the NHS, especially given England’s ageing population, with an estimated two-thirds of individuals aged 65 and over having 2 or more long-term conditions (5-6). Yet, little is known about the resource use of these patients despite being the group with the largest impact on the NHS and with the worst health outcomes (7). Existing evidence focuses on specific health conditions and their interactions with other conditions using different methodologies, making comparisons across different conditions difficult. This work has empirically assessed the impact of multi-morbidity on NHS and social care costs. With the aim of answering the question: is the impact of developing a condition on health and social care costs greater for someone with no prior conditions, or for someone with an existing condition. If patients have multiple conditions, there may be some economies of scale involved with treatment, for example they may be able to discuss multiple queries during a single GP appointment, or in some cases the treatment provided will address multiple conditions. However, treating patients with multi-morbidities could theoretically also be more expensive than treating 2 conditions separately, as patients may be more likely to experience complications. Methodology This work considered the individual cost of 11 health conditions with high prevalence in the English population and their most common interactions. These were: chronic obstructive pulmonary disease (COPD), diabetes (types 1 and 2), lung cancer, breast cancer, coronary heart disease (CHD), stroke, hypertension, dementia, liver disease, depression and colorectal cancer. This project had 2 components: a literature review and an empirical estimation of the costs associated with MM. The literature review was used to inform and establish the methodology used in the empirical estimation. The empirical estimation used data on primary healthcare, secondary healthcare, and prescriptions usage from 2015 to estimate annual aggregated healthcare costs per patient. We assessed the cost impact of MM in a systematic way by applying advanced econometric methods to account for the specificities of the data distribution. Our methodology allowed us to attribute healthcare costs to specific conditions. For social care costs, we calculated the estimated costs using 2 different methodologies. For the first (preferred) methodology, we used Somerset Symphony data to calculate the 2014/15 social care costs of patients in South Somerset. This is a dataset that combines primary healthcare, secondary healthcare, and social care data. We thus applied the same methodology that was used to calculate primary and secondary healthcare costs. For the second methodology, we used the estimated health-related quality of life for patients with different conditions and combinations of conditions. We then used a regression (‘line of best fit’) to estimate their probability of requiring social care. Finally, we used unit cost estimates to arrive at estimated values for the costs of social care for individuals with different diseases. What this publication adds Average ‘cost per case’ estimates for individuals with single conditions or multimorbidities, each calculated based on the average age of patients with the condition or multi-morbidity of interest. These average ‘costs per case’ figures are always higher for individuals with multimorbidities than individuals with a single condition, as individuals with multi-morbidities tend to be older and additional conditions incur additional costs. We found that the cost of treating an individual with a multimorbidity is not statistically different than the additive cost of treating 2 individuals, each with one of the conditions, controlling for age and costs unrelated to the condition. As an illustrative example, if it costs £200 to treat a patient with depression and £200 to treat a patient with CHD, we did not find any evidence that it would cost more than £400 to treat a single patient with both depression and CHD (controlling for age and unrelated disease costs). In numerous cases, when considering healthcare costs, we have found that multimorbidity is associated with a reduction of the total individual cost compared to the sum of individual costs of patients. For example, a male patient with diabetes and CHD will cost between 77% and 78% (depending on the definition of sample prevalence) of the cost of treating 2 patients, one with diabetes and one with CHD, controlling for age and unrelated costs. Applying the same methodology for social care costs as for healthcare costs, we did not find any evidence that multi-morbidity is associated with either an increase or a reduction in total individual cost compared to the sum of individual costs of patient, for social care costs. This may be due to the relatively small sample size of the South Somerset data we used to estimate social care costs. Applying the alternative methodology for social care costs, which estimated social care need based on age and quality of life, we estimated higher social care costs than we found by analysing the South Somerset data. This implies that social care need may be greater than local authority social costs in South Somerset. This may be due to the relative affluence of South Somerset, which would limit the proportion of patients eligible for local authority-funded social care

Sustainability orientation, CSR implementation and new venture growth

Purpose: Building on the upper echelons theory and sustainability orientation (SO) literature, we examined the possibility that the relationship between chief executive officers’ (CEOs’) SO and venture growth might be mediated by levels of CSR implementation. Design/methodology/approach: We used data obtained from from 211 new ventures operating in Ghana. Multiple regression analysis was used to test the hypotheses. Findings: We found that CSR implementation mediates the relationship between SO and venture growth. In addition, we found that, at higher levels of financial slack, the effect of SO on CSR implementation is attenuated. However, our results show that, at higher levels of CEO power, the influence of SO on CSR implementation is amplified. Originality: To the best of our knowledge, this study is among the first to examine mediating role of CSR implementation in the relationship between SO and venture growth, and also, examines two internal contingency factors (i.e., CEO power and financial slack) on this association. Theoretical/Academic Implications: This study builds on prior scholarly works by articulating a key managerial characteristic that shapes the implementation of environmental and social policies. Specifically, we show that SO influences venture growth through CSR implementation. We also provide insights on the connection of CSR implementation to growth of new business ventures. Practitioner/Policy Implications: Our study encourages CEOs to voluntarily adopt CSR and sustainability initiatives. The analysis also reinforces the need that higher levels of CEO power have a major impact in amplifying the effects of sustainability orientation on degree of CSR implementation. There is a need for government to create forums where organizational decisionmakers, i.e., CEOs, exchange not only the best knowledge about CSR implementation and sustainability, but also best practices to provide opportunities for cross fertilization of ideas and increased innovations

Resistance screening of white yam (Dioscorea rotundata Poir.) accessions against Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949 using yam vines

Open Access Article; Published online: 05 Apr 2022Root-knot nematode (Meloidogyne incognita) is an economically important phytoparasitic nematode species. In yam production, therefore, breeding for nematode resistance is an important environmentally friendly tool to manage root-knot nematodes damage. The aim of this study was to determine the reaction of 18 yam accessions to M. incognita inoculation under screen house conditions using single node vine cuttings. Vines of each accession were planted in sterilized soil and inoculated with 1000 infective juveniles of M. incognita. Resistance level of yam accessions were based on both galling index score and reproductive factor. There were a significant differences in final infective stage nematodes population, galling index, reproduction factor and yield of mini tuber among the accessions tested. Sixteen (89 %) of the accessions showed moderate resistance (GI ≥ 2, Rf ≤ 1) to the test pathogen with two accessions classified as susceptible. Accession TDr1515OP16/0030 recorded the highest mini tuber yield mass of 19.4 g, which was 74 % higher than accession ‘TDr1515OP16/0108’ which recorded the lowest yield of 10.4 g. The moderately resistant accessions identified in the study can be utilized to reduce nematodes reproduction and help manage root-knot nematode in yam production

Clinical features of COVID-19 in Ghana: symptomatology, illness severity and comorbid non-communicable diseases

Objective: This analysis described the clinical features of COVID-19 in the early phase of the pandemic in Ghana.Methods: Data were extracted from two national COVID-19 treatment centers in Ghana for over 11 weeks(from March to May 2020). Descriptive and inferential statistics were performed. Modified Ordered Logistic and Negative Binomial Regression analysis were applied to establish factors associated with illness severity and Non-communicable Disease (NCDs) counts respectively. All analysis was conducted at the 95% confidence level (p-value ≤ 0.05) using Stata 16.Results: Among the 275 patients, the average age was 40.7±16.4, with a preponderance of males (54.5%). The three commonest symptoms presented were cough (21.3%), headache (15.7%), and sore throat (11.7%). Only 7.6% of the patients had a history of fever. Most patients were asymptomatic (51.65). Approximately 38.9% have an underlying co-morbid NCDs, with Hypertension (32.1%), Diabetes (9.9%), and Asthma (5.2%) being the three commonest. The odds of Moderate/severe (MoS) was significantly higher for those with unknown exposures to similar illness [aOR(95%CI) = 4.27(1.12-10.2)] compared with non-exposure to similar illness. An increased unit of NCD’s count significantly increased the odds of COVID-19 MoS illness by 26%[cOR(95%CI) =1.26(1.09-1.84)] and 67% (adjusting for age) [aOR(95%CI)=1.67(1.13-2.49)].Conclusion: The presence of cardiovascular co-morbidities dictated the frequency of reported symptoms and severity of COVID-19 infection in this sample of Ghanaians. Physicians should be aware of the presence of co-morbid NCDs and prepare to manage effectively among COVID-19 patients

Environmental Sustainability Practices and Offshoring Activities of Multinational Corporations Across Emerging and Developed Markets

Using panel data of 1080 multinational corporations (MNCs) from the United States, we examine the effects of environmental sustainability practices on the degree of firms’ offshoring activities. In addition, we disaggregate offshoring activities into their core components depending on whether or not the firm buys (inputs) or sells (outputs) and/or owns assets in a given country and examine the extent to which sustainability practices influence the different components of offshoring decisions. The results indicate that sustainability practices significantly affect offshoring activities of MNCs. In particular, we found that sustainable business practices matter when the firm sells goods or owns assets in the given host nation. Additionally, the results show that the sustainability–degree of the internationalization relationship is crucial for MNCs that have offshoring activities in advanced economies relative to those firms that have activities in emerging markets. Our results are robust to alternative explanations
