CHEMICAL COMPOSITIONS, ANTIOXIDANT CAPACITY OF TIGERNUT (Cyperus esculentus) AND POTENTIAL HEALTH BENEFITS

Tiger nut (Cyperus esculentus L.) considered as an intrusive weed in most countries but taken as snack in Nigeria was analyzed for proximate and mineral compositions using standard analytical techniques. Antioxidant activity of the methanolic extract was measured using 2, 2-diphenyl-1- picryhydrazyl (DPPH), while the total phenolic content was determined according to Folin-Ciocalteu method. The results revealed that the three forms of the tuber (dry, raw and roasted) as consumed had % moisture ranging from (12.57-43.84); protein (1.32-2.24); fat (1.44-1.54); ash (3.34- 6.69); crude fibre (16.14-17.14); and carbohydrate (30.58-62.79). The samples were significantly high in Na, K and Ca. Na-K ratio was also found to be less than 1 suggesting its suitability in formulating diets for hypertensive patients. Antioxidant activity of the samples ranged from 3.72- 5.90; 5.22-9.72; 11.63-16.10; and 15.95-23.00 % inhibitions at different levels of concentrations while total phenolic content ranged from (806.7- 1150.7) micromole GAE/g. The results indicate that the edible tubers which are used for non-alcoholic local beverage formulation, in medicine and cosmetic industry can be utilized to ‘mop up’ and scavenge free-radicals generated by essential metabolic body reactions and environmental pollutants. It is hoped that addition of tiger nut as side dish and adjunct in traditional diets will probably alleviate the symptoms associated with neurodegenerative and cardiovascular diseases

Understanding the Impact of Strategic Change Management on the Maritime Crude Oil Transportation Industry in Nigeria

Maritime transportation plays a strategically crucial role in the diversification of the Nigerian economy due to its trade (exports and imports) facilitation role in enhancing value chain competitiveness. Thus, this article investigates the role of strategic change management (SCM) on the Nigerian Maritime Crude Oil Transportation Industry (MCOTI) within the context of Sustainable Development Goals (SDGs). Furthermore, the study finds that both managers and end users think a “radical change” rather than a “gradual change” is needed in the MCOTI in Nigeria. However, both managers and end users gave significantly different reasons for a radical change in the industry. For example, most managers argued that government intervention through deregulation, increased investment in technology, and trade facilitation infrastructural development are critical for the survival, restructuring, repositioning, expansion, and growth of the industry (in terms of ship registry and number of cabotage vessels in Nigerian coastal waters), whereas end users focused on product pricing and availability as well as increased opportunities for the vulnerable and economically disadvantaged

Perceived Service Quality of Architectural Consultancy Firms and Client Satisfaction in Building Projects in Nigeria

Purpose Clients in Nigeria have continuously questioned the quality of services being rendered by architectural firms in building projects. This study aims to investigate the areas of service responsible for determining client satisfaction. Design/methodology/approach The study uses questionnaire for data collection on perceived service quality and indicators of clients’ satisfaction. Findings The results of descriptive statistics suggest that efficient analysis and compliance with client brief along with buildability, flexibility and comprehensiveness of the design are the main technical determinants of clients’ satisfaction. Management measures for engendering clients’ satisfaction include team communication and collaboration as well as regular site visits when required. The study established a significant relationship between the perceived service quality and client satisfaction. At technical level, economical design and compliance with budget, buildability, optimal and error-free design and timely delivery have significant correlation with the perception of service quality, which could engender client satisfaction. At management level, collaboration and coordination, integrity and trust, regular site visits and project management knowledge and skills had significant relationships with perceived service quality. Originality/value To improve overall client satisfaction, architects are expected to focus on these factors in the process of service delivery. Architects’ expertise and skills can be further harnessed through continuous training and understanding of the project environment

Census politics in deeply divided societies

Population censuses in societies that are deeply divided along ethnic, religious or linguistic lines can be sensitive affairs – particularly where political settlements seek to maintain peace through the proportional sharing of power between groups. This brief sets out some key findings from a research project investigating the relationship between census politics and the design of political institutions in Bosnia and Herzegovina, Kenya, Lebanon and Northern Ireland

Interventions to increase attendance for diabetic retinopathy screening

BACKGROUND: Despite evidence supporting the effectiveness of diabetic retinopathy screening (DRS) in reducing the risk of sight loss, attendance for screening is consistently below recommended levels.OBJECTIVES: The primary objective of the review was to assess the effectiveness of quality improvement (QI) interventions that seek to increase attendance for DRS in people with type 1 and type 2 diabetes.Secondary objectives were:To use validated taxonomies of QI intervention strategies and behaviour change techniques (BCTs) to code the description of interventions in the included studies and determine whether interventions that include particular QI strategies or component BCTs are more effective in increasing screening attendance;To explore heterogeneity in effect size within and between studies to identify potential explanatory factors for variability in effect size;To explore differential effects in subgroups to provide information on how equity of screening attendance could be improved;To critically appraise and summarise current evidence on the resource use, costs and cost effectiveness.SEARCH METHODS: We searched the Cochrane Library, MEDLINE, Embase, PsycINFO, Web of Science, ProQuest Family Health, OpenGrey, the ISRCTN, ClinicalTrials.gov, and the WHO ICTRP to identify randomised controlled trials (RCTs) that were designed to improve attendance for DRS or were evaluating general quality improvement (QI) strategies for diabetes care and reported the effect of the intervention on DRS attendance. We searched the resources on 13 February 2017. We did not use any date or language restrictions in the searches.SELECTION CRITERIA: We included RCTs that compared any QI intervention to usual care or a more intensive (stepped) intervention versus a less intensive intervention.DATA COLLECTION AND ANALYSIS: We coded the QI strategy using a modification of the taxonomy developed by Cochrane Effective Practice and Organisation of Care (EPOC) and BCTs using the BCT Taxonomy version 1 (BCTTv1). We used Place of residence, Race/ethnicity/culture/language, Occupation, Gender/sex, Religion, Education, Socioeconomic status, and Social capital (PROGRESS) elements to describe the characteristics of participants in the included studies that could have an impact on equity of access to health services.Two review authors independently extracted data. One review author entered the data into Review Manager 5 and a second review author checked them. Two review authors independently assessed risks of bias in the included studies and extracted data. We rated certainty of evidence using GRADE.MAIN RESULTS: We included 66 RCTs conducted predominantly (62%) in the USA. Overall we judged the trials to be at low or unclear risk of bias. QI strategies were multifaceted and targeted patients, healthcare professionals or healthcare systems. Fifty-six studies (329,164 participants) compared intervention versus usual care (median duration of follow-up 12 months). Overall, DRS attendance increased by 12% (risk difference (RD) 0.12, 95% confidence interval (CI) 0.10 to 0.14; low-certainty evidence) compared with usual care, with substantial heterogeneity in effect size. Both DRS-targeted (RD 0.17, 95% CI 0.11 to 0.22) and general QI interventions (RD 0.12, 95% CI 0.09 to 0.15) were effective, particularly where baseline DRS attendance was low. All BCT combinations were associated with significant improvements, particularly in those with poor attendance. We found higher effect estimates in subgroup analyses for the BCTs 'goal setting (outcome)' (RD 0.26, 95% CI 0.16 to 0.36) and 'feedback on outcomes of behaviour' (RD 0.22, 95% CI 0.15 to 0.29) in interventions targeting patients, and 'restructuring the social environment' (RD 0.19, 95% CI 0.12 to 0.26) and 'credible source' (RD 0.16, 95% CI 0.08 to 0.24) in interventions targeting healthcare professionals.Ten studies (23,715 participants) compared a more intensive (stepped) intervention versus a less intensive intervention. In these studies DRS attendance increased by 5% (RD 0.05, 95% CI 0.02 to 0.09; moderate-certainty evidence).Fourteen studies reporting any QI intervention compared to usual care included economic outcomes. However, only five of these were full economic evaluations. Overall, we found that there is insufficient evidence to draw robust conclusions about the relative cost effectiveness of the interventions compared to each other or against usual care.With the exception of gender and ethnicity, the characteristics of participants were poorly described in terms of PROGRESS elements. Seventeen studies (25.8%) were conducted in disadvantaged populations. No studies were carried out in low- or middle-income countries.AUTHORS' CONCLUSIONS: The results of this review provide evidence that QI interventions targeting patients, healthcare professionals or the healthcare system are associated with meaningful improvements in DRS attendance compared to usual care. There was no statistically significant difference between interventions specifically aimed at DRS and those which were part of a general QI strategy for improving diabetes care. This is a significant finding, due to the additional benefits of general QI interventions in terms of improving glycaemic control, vascular risk management and screening for other microvascular complications. It is likely that further (but smaller) improvements in DRS attendance can also be achieved by increasing the intensity of a particular QI component or adding further components.</p

Manpower capacity and reasons for staff shortage in primary health care maternity centres in Nigeria: A mixed-methods study

The heart-breaking maternal and neonatal health indicators in Nigeria are not improving despite previous interventions, such as ‘Health for all’ and ‘Millennium Development Goals. The unattained health-related goals/targets of previous interventions put the success of the new Sustainable Development Goals in doubt if the existing paradigm remains unchanged. Thus, mere branding of health policies without improving what constitutes the health system such as manpower capacity and quality as well as staff-patients ratio will be wasteful efforts. This issue of global public health concern provided an indication for describing the capacity of manpower and reasons for staff shortage in primary level of health that are providing maternity services to women and their new-borns in Nigeria

Novice Learner Experiences in Software Development: A Study of Freshman Undergraduates

This paper presents a study that is part of a larger research project aimed at addressing the gap in the provision of educational software development processes for freshman, novice undergraduate learners, to improve proficiency levels. With the aim of understanding how such learners problem solve in software development in the absence of a formal process, this case study examines the experiences and depth of learning acquired by a sample set of novice undergraduates. A novel adaption of the Kirkpatrick framework known as AKM-SOLO is used to frame the evaluation. The study finds that without the scaffolding of an appropriate structured development process tailored to novices, students are in danger of failing to engage with the problem solving skills necessary for software development, particularly the skill of designing solutions prior to coding. It also finds that this lack of engagement directly impacts their affective state on the course and continues to negatively impact their proficiency and affective state in the second year of their studies leading to just under half of students surveyed being unsure if they wish to pursue a career in software development when they graduate

Single Feature Polymorphism Discovery in Rice

The discovery of nucleotide diversity captured as single feature polymorphism (SFP) by using the expression array is a high-throughput and effective method in detecting genome-wide polymorphism. The efficacy of such method was tested in rice, and the results presented in the paper indicate high sensitivity in predicting SFP. The sensitivity of polymorphism detection was further demonstrated by the fact that no biasness was observed in detecting SFP with either single or multiple nucleotide polymorphisms. The high density SFP data that can be generated quite effectively by the current method has promise for high resolution genetic mapping studies, as physical location of features are well-defined on rice genome

Comparative study of the functional properties of three legume seed isolates: adzuki, pea and soy bean

The aim of this work was to compare functional properties including solubility, emulsifying and foaming properties of native and thermally treated adzuki, soy and pea protein isolates prepared under the same conditions. These functional properties were tested at four pH values: pH 3.0, pH 5.0, pH 7.0 and pH 8.0. The lowest solubility at all pH values were obtained for isolate of adzuki whereas isolates of soybean had the highest values at almost all pHs. Thermal treatment reduced solubility of soy and pea isolates at all pH values, whereas solubility of adzuki isolate was unchanged, except at pH 8. Native isolate of adzuki had the best emulsifying properties at pH 7.0 whereas at the other pH values some of native pea and soybean protein isolates were superior. After thermal treatment, depending on tested pH and selected variety all of three species could be a good emulsifier. Native soy protein isolates formed the most stable foams at all pHs. Thermal treatment significantly improved foaming properties of adzuki isolate, whereas reduced foaming capacity of soy and pea isolates, but could improve foam stability of these isolates at specific pH. Appropriate selection of legume seed as well as variety could have great importance in achievement of desirable functional properties of final products. All three tested species could find specific application in wide range of food products
