CHILDREN LITERATURE: BEDROCK OF SUSTAINABLE DEVELOPMEN

Education is the bedrock of any nation, and Nigeria is no exception. It is a critical pillar of sustainable human development without which we stagnate, flounder, and become inert. Education can also be referred to as the bedrock of social, economic and political development. It is important for creating enabling conditions for sustaining change. A well educated populace (which begins with a child) is necessary to bring about technological innovations and to adapt and modify it in the context of local conditions and realities. Only education can equip children with the confidence to make the most of their abilities. Quality education and basic literacy will open doors to information technology and the “new economyâ€. According to Jegede (2006), effective national development depends on education whose bedrock is the acquisition of knowledge. A learning society is a knowledgeable and wise society. What a person imbibes from childhood forms the basis of his attitude in life hence in Yoruba culture, a child is taught the norms and values of the society right from childhood through diverse means, one of which is children poems. These poems are didactic and they cover a wide range of themes. The language is very simple and they are easy to remember. They mould children’s attitude as they journey through life. This paper discussed educating children through poems. The poems of Olatubosun and Odunjo were used as case study

An analysis of selected cases

Funding Information: This work was supported by Project CESME (Collaborative & Evolvable Smart Manufacturing Ecosystem) and the Portuguese FCT program UIDB/00066/2020. Publisher Copyright: © 2022 The Author(s)The rapid proliferation of renewable energy communities/ecosystems is an indication of their potential contribution to the ongoing energy transition. A common characteristic of these ecosystems is their complex composition, which often involves the interaction of multiple actors. Currently, the notions of "networking", "collaboration", "coordination", and "cooperation", although having different meanings, are often loosely used to describe these interactions, which creates a sense of ambiguity and confusion. To better characterize the nature of interactions in current and emerging ecosystems, this article uses the systematic literature review method to analyse 34 emerging cases. The objective is threefold (a) to study the interactions and engagements between the involved actors, aiming at identifying elements of collaboration. (b) Identify the adopted technological enablers, and (c) ascertain how the composition and functions of these ecosystems compare to virtual power plants. The outcome revealed that the interactions between the members of these ecosystems can be described as cooperation and not necessarily as collaboration, except in a few cases. Regarding technological enablers, a vast panoply of technologies, such as IoT devices, smart meters, intelligent software agents, peer-to-peer networks, distributed ledger systems/blockchain technology (including smart contracts, blockchain as a platform service, and cryptocurrencies) were found. In comparison with virtual power plants, these ecosystems have similar composition, thus, having multiple actors, comprised of decentralized and heterogeneous technologies, and are formed by aggregating various distributed energy resources. They are also supported by ICT and are characterized by the simultaneous flow of information and energy.publishersversionpublishe

Politics and Politicking: The Organizational Perspective

The totality of our community, society, the whole world and even the entire universe is an organization. Organizing involves developing a structure of roles for effective performance and it requires a network of decision and communication for coordinating efforts towards group and enterprise goals. For effectiveness an organizational structure must be understood and principles and policies must be put into practice through the structural organizational politics. Power and politics are interrelated and interwoven with the fabric of an organization. Politics, power and politicizing are necessary, unavoidable and inevitable. The paper therefore examined the features of organizational structure, sources of power, leadership styles, features and tactics of organizational politics. The paper equally examined the mistakes in organizational setting and way out. It was then concluded that effective managers need to be fully aware of the existence of political tactics, have the required wisdom, knowledge, skill and should learn how best to manage the organizational politics for the efficacy of the organizational setting.

Assessment and Impacts of Metal Recycling on Groundwater Quality in Ogijo, Ogun State, Nigeria

Groundwater is an essential source of water supply globally. Recently, however, the groundwater environment is being threatened due to heavy metal contamination resulting from the indiscriminate use, storage, and disposal of toxic metal elements. This study evaluates heavy metals concentrations in groundwater systems close to a metal recycling industry in Ogun State, Nigeria. In the study, thirty-six (36) water samples were collected from boreholes within the vicinity of a metal recycling industry and analysed using the atomic absorption spectrophotometer. Water samples collected had trace concentrations of iron (Fe), copper (Cu), lead (Pb), manganese (Mn), zinc (Zn), chromium (Cr), cadmium (Cd), and nickel (Ni); metal concentrations were highest in the borehole closest to the industry. Pb, Cr, and Mn concentrations were above the acceptable standards. The findings showed that the activities within metal recycling industries can potentially elevate toxic metal concentrations in groundwater water sources close to it if proper mitigation measures are not put in place

An Examination of Selected Small Livestock Producers’ Implementation of Identified Best Practices in Alabama

Getting small farmers to adopt “best practices” has been a key challenge in general, but particularly, in the Southeastern U.S. This study focused on selected small livestock producers’ implementation identified best practices in Alabama. Data were obtained through interviews from twelve producers in, primarily, selected South Central Alabama counties emphasizing best practices as well as other production indicators. The subjects were mainly beef cattle and meat goat producers. The identified best practices were: rotational grazing, soil testing, quarantining, deworming, veterinary services, and record keeping. The data were analyzed using descriptive narrative and simple statistics. The demographics showed more male than female producers, and more meat goat producers than beef cattle producers. Also, the results revealed that the commonest best practice was deworming; followed by quarantining, soil testing and record keeping, and rotational grazing. Using veterinary services was the least practiced best practice; most producers chose to provide their own animal health services. The results provide an opportunity for assistance providers to educate producers on the importance of adopting the best practices.

Effect of processing on the quality, composition and antioxidant properties of Terminalia catappa (Indian almond) seed oil

This study was aimed at extracting and purifying T. catappa seed oil with a view to investigating the effect of processing on the composition and antioxidant activity of the oil. Oil was extracted from the dried and roasted T. catappa seed and subjected to degumming and bleaching. The different processed oils were analysed for their fatty acid, phytosterols, and fat soluble vitamins composition. Antioxidant properties of the oils were also determined by measuring the Diphenylpicrylhydrazyl (DPPH) radical scavenging activity and inhibition of heat induced peroxidation. Roasting and processing caused a reduction in acid value, increased peroxide value, but had no effect on the iodine and saponification values of T. catappa oil. Palmitic acid was the most abundant saturated fatty acid (42.466%) while oleic acid was the most abundant unsaturated fatty acid (23.445%). Roasting significantly reduced fatty acid concentration of the oil, and bleaching of both unroasted and roasted oils increased the concentration of fatty acids except linoleic acid. Gamma-sitosterol and Betasitosterol were present in appreciable amounts only in the crude oils. Roasting increased Vitamins A and D concentrations but drastically reduced that of vitamin E. Degumming had no effect on the fat soluble vitamins of T. catappa oil, but bleaching significantly reduced the concentrations of all the vitamins. The DPPH radical scavenging activity of the seed oil was between 26.93 ± 15.42% and 65.47 ± 31.59%. Refining increased the free radical scavenging activity of the unroasted oil, but did not affect the antioxidant activity of roasted oil. The capacity of the oil in preventing heat induced peroxidation was comparable to that of Butylated hydroxytoluene (BHT). Processing of the oil significantly increased its antioxidant activity. Loss of vitamin E did not affect the antioxidant activity of the oil. Thus, suggesting the presence of a heat stable antioxidant in the oil. This study indicated T. catappa seed oil to be potential pharmaceutical oil with good antioxidant characteristics.Key words: Terminalia catappa, composition, antioxidant, processing, oi

Protein and energy requirements for indigenous guinea keets (Numida meleagris) in southern Ghana

One thousand two hundred healthy unsexed unsexed keets were used in an 8-week feeding trial that aimed at determining the protein and energy requirements during the starter phase of local guinea fowls reared in coastal savanna part of Ghana. The keets were randomly allocated in a 3 X 2 factorial design to six dietary treatments (three crude protein levels and two energy levels) in a deep litter system. Each treatment had 200 keets and was replicated four times with 50 keets per replicate. The six dietary treatments were designated as follows: T1 (23% CP and 11.5 MJ ME/kg), T2 (24% CP and 11.5 MJ ME/kg), T3 (25% CP and 11.5 MJ ME/kg), T4 (23% CP and 12.5 MJ ME/kg), T5 (24% CP and 12.5 MJ ME/kg), and T6 (25% CP and 12.5 MJ ME/kg). A known daily quantity of feed was given each replicate early in the morning while water was provided ad libitum. The same diets were fed for the entire duration of the study. Feed intake, weight gain, feed conversion ratio, economy of gain and mortality were determined and use as indices of evaluation. The feed intake per keet per day increased with the lower energy level diets (T1, T2 and T3) (P < 0.05). Dietary treatments T5 and T6 had the highest (P < 0.05) daily weight gains of 8.61 and 8.38 g/day respectively. The feed conversion ratios of the keets were 4.18, 4.20, 4.13, 4.32, 3.46 and 3.60 for T1, T2, T3, T4, T5 and T6, respectively. T5 diet had the least (P < 0.05) feed costs per kg gain ($/kg gain) value of 1.63. The study indicated that protein and energy required by guinea keets during the first 8 weeks of growth could be put at 24 percent CP and 12.5 MJ ME/kg, respectively

Blockchain-Enabled Provenance Tracking for Sustainable Material Reuse in Construction Supply Chains

The growing complexity of construction supply chains and the significant impact of the construction industry on the environment demand an understanding of how to reuse and repurpose materials. In response to this critical challenge, research gaps that are significant in promoting material circularity are described. Despite its potential, the use of blockchain technology in construction faces challenges in verifiability, scalability, privacy, and interoperability. We propose a novel multilayer blockchain framework to enhance provenance tracking and data retrieval to enable a reliable audit trail. The framework utilises a privacy-centric solution that combines decentralised and centralised storage, security, and privacy. Furthermore, the framework implements access control to strengthen security and privacy, fostering transparency and information sharing among the stakeholders. These contributions collectively lead to trusted material circularity in a built environment. The implementation framework aims to create a prototype for blockchain applications in construction supply chains

Influence of crop residue ration supplementation on the attainment of puberty and postpartum reproductive activities of Red Sokoto goats

The general objective of this study was to come up with an appropriate, affordable and locally available crop residue supplementation package that would enhance reproductive performance in small ruminants. Specifically, 28 Red Sokoto weaner does between 3 and 4 months of age weighing between 2 and 3 kg were used in the first experiment to determine the influence of crop residue supplementation on age and weight at puberty as determined by blood progesterone levels. In the second experiment, another 28 adult does (equal to or greater than 2 years old) of the same breed in the same flock with lactation numbers between 1 and 3 were used to determine the length of postpartum acyclic period. In both experiments, a 3 x 2 factorial experimental design comprising three dietary supplements (A, B, C) at two feeding levels (1% and 2% of body weight) fed in addition to a basal diet of Digitaria smutsii hay and natural pasture ad libitum with an unsupplemented negative control group (D) and four goats per treatment was utilized. In ration A, a conventional concentrate supplement consisting of maize, wheat offal, cottonseed cake and bonemeal was utilized; in rations B and C, the supplement consisted of guinea-corn bran, cowpea husk and groundnut haulms; and maize offal, groundnut shells and groundnut haulms respectively. Unsupplemented (ration D) weaner does reached puberty at a later age and had lighter body weights than all the others. Weaner does on ration 2A (concentrate fed at 2% of body weight) attained puberty at the earliest age and heaviest body weight, although the age at puberty was not significantly different from those on rations 1A (concentrate fed at 1% body weight), 1C and 2C. Blood progesterone profiles before and after puberty ranged from 0.05 to 9.0 ng/ml, respectively, and was highest in does fed rations A and C and least in the unsupplemented does. The mean interval between kidding and initiation of ovarian activity was 54.28 plus or minus 17.61 days and the mean interval between kidding and conception was 63.04 plus or minus 25.34 days. Only 25% of the unsupplemented does conceived again during the period under study compared with 100% in rations 1A, 2A, 1C and 2C; 75% in ration 2B and 50% in ration 1B. It was concluded that implementation of supplementary feeding in the dry season improves reproductive performance in the Red Sokoto doe. Furthermore, ration C, a crop residue-based ration, was a suitable dry season supplementation alternative to the expensive conventional concentrate ration for the smallholder goat farmer in the subhumid tropics of Nigeria

White Matter Integrity and Processing Speed in Sickle Cell Anemia

Objective The purpose of this retrospective cross-sectional study was to investigate whether changes in white matter integrity are related to slower processing speed in sickle cell anemia. Methods Thirty-seven patients with silent cerebral infarction, 46 patients with normal MRI, and 32 sibling controls (age range 8–37 years) underwent cognitive assessment using the Wechsler scales and 3-tesla MRI. Tract-based spatial statistics analyses of diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) parameters were performed. Results Processing speed index (PSI) was lower in patients than controls by 9.34 points (95% confi- dence interval: 4.635–14.855, p = 0.0003). Full Scale IQ was lower by 4.14 scaled points (95% confidence interval: −1.066 to 9.551, p = 0.1), but this difference was abolished when PSI was included as a covariate (p = 0.18). There were no differences in cognition between patients with and without silent cerebral infarction, and both groups had lower PSI than controls (both p < 0.001). In patients, arterial oxygen content, socioeconomic status, age, and male sex were identified as predictors of PSI, and correlations were found between PSI and DTI scalars (fractional anisotropy r = 0.614, p < 0.00001; r = −0.457, p < 0.00001; mean diffusivity r = −0.341, p = 0.0016; radial diffusivity r = −0.457, p < 0.00001) and NODDI parameters (intracellular volume fraction r = 0.364, p = 0.0007) in widespread regions. Conclusion Our results extend previous reports of impairment that is independent of presence of infarction and may worsen with age. We identify processing speed as a vulnerable domain, with deficits potentially mediating difficulties across other domains, and provide evidence that reduced processing speed is related to the integrity of normal-appearing white matter using microstructure parameters from DTI and NODDI
