Attitude of undergraduate students to information literacy: Bowen University experience

The study investigated the rationale behind undergraduates’ apathy for information literacy (IL) programme at Bowen University, Nigeria. A descriptive survey design was adopted for the study and a multi-stage sampling method was used to select a sample size of five hundred participants spread across disciplines and levels of study. A questionnaire containing closeended, structured items was used to gather data from the respondents and descriptive analyses, including percentages and frequency count were used to analyse the data collected. Three research questions were developed and answered and three research hypotheses were tested through the instrument. Results show that students’ attitude to information literacy significantly influences their information literacy skill and students’ perception of information literacy significantly influences their information literacy skills. Although perception of IL does not predict influence of IL on students, attitude to IL determines the influence of IL on students’ information literacy skills. The study further revealed that the erroneous equation of technology literacy with information literacy was largely responsible for students' lukewarm disposition to information literacy. The study concludes by recommending a paradigm shift from the traditional teaching delivery to a technology-driven, interactive pedagogy that will ginger the interest of the students and thus effect the desired attitudinal change to IL

How Careers Advice and Guidance can Facilitate Career Development in TVET Graduates: The case in Nigeria

This study examined the current state of careers advice, guidance, and counselling (CAGC) services and programs in the technical, vocational education, and training (TVET) system of Nigerian higher education institutions (HEIs). This was to determine how well current CAGC services and programs foster students’ career development, aspirations, and choices. Forty-eight participants, who were members of the Nigerian National Board for Technical Education (8 participants), guidance counsellors (6), university TVET teachers (18), career experts from the National Directorate of Employment (7), and newly employed TVET graduates (9), volunteered for the study. A purposeful sampling procedure was adopted to recruit participants. Data were collected using a semi-structured interview approach, and we employed a thematic design for the coding and analysis of the transcribed data. The study found no CAGC services and programs in the TVET system. It is recommended, therefore, that TVET systems should focus on providing career development enhanced learning rather than schooling only by revising the curriculum to include programs and activities that promote CAGC activities and programs

Oscillatory Shear Flow-Induced Alignment of Lamellar Melts of Hydrogen-Bonded Comb Copolymer Supramolecules

In this work we present the orientational behavior of comb copolymer-like supramolecules P4VP(PDP)1.0, obtained by hydrogen bonding between poly(4-vinylpyridine) and pentadecylphenol, during large-amplitude oscillatory shear flow experiments over a broad range of frequencies (0.001-10 Hz). The alignment diagram, presenting the macroscopic alignment in T/TODT vs ω/ωc, contains three regions of parallel alignment separated by a region of perpendicular alignment. For our material, the order-disorder temperature TODT = 67 °C and ωc, the frequency above which the distortion of the chain conformation dominates the materials’ viscoelasticity, is around 0.1 Hz at 61 °C. For the first time flipping from a pure transverse alignment via biaxial transverse/perpendicular alignment to a perpendicular alignment as a function of the strain amplitude was found.

Gene content evolution in the arthropods

Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome. Dissection of the genomic record of sequence change enables broad questions regarding genome evolution to be addressed, even across hyper-diverse taxa within arthropods. Using 76 whole genome sequences representing 21 orders spanning more than 500 million years of arthropod evolution, we document changes in gene and protein domain content and provide temporal and phylogenetic context for interpreting these innovations. We identify many novel gene families that arose early in the evolution of arthropods and during the diversification of insects into modern orders. We reveal unexpected variation in patterns of DNA methylation across arthropods and examples of gene family and protein domain evolution coincident with the appearance of notable phenotypic and physiological adaptations such as flight, metamorphosis, sociality, and chemoperception. These analyses demonstrate how large-scale comparative genomics can provide broad new insights into the genotype to phenotype map and generate testable hypotheses about the evolution of animal diversity

Fluorosis risk from early exposure to fluoride toothpaste

Swallowed fluoride toothpaste in the early years of life has been postulated to be a risk factor for fluorosis, but the epidemiological evidence is weakened by the fact that most of the relevant studies were done in developed countries where an individual is exposed to multiple sources of fluoride. Objectives: To quantify the risk of fluorosis from fluoride toothpaste in a population whose only potential source of fluoride was fluoride toothpaste. Methods: Case-control analyses were conducted to test the hypothesis that fluoride toothpaste use before the age of 6 years increased an individual's risk of fluorosis. Data came from a cross-sectional clinical dental examination of schoolchildren and a self-administered questionnaire to their parents. The study was conducted in Goa, India. The study group consisted of 1189 seventh grade children with a mean age of 12.2 years. Results: The prevalence of fluorosis was 12.9% using the TF index. Results of the crude, stratified, and logistic regression analyses showed that use of fluoride toothpaste before the age of 6 years was a risk indicator for fluorosis (OR 1.83, 95% CI 1.05–3.15). Among children with fluorosis, beginning brushing before the age of 2 years increased the severity of fluorosis significantly ( P < 0.001). Other factors associated with the use of fluoride toothpaste, such as eating or swallowing fluoride toothpaste and higher frequency of use, did not show a statistically significant increased risk for prevalence or severity of fluorosis. Conclusions: Fluoride toothpaste use before the age of 6 years is a risk indicator for fluorosis in this study population.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/75437/1/j.1600-0528.1998.tb01957.x.pd

The possible role of local air pollution in climate change in West Africa

The climate of West Africa is characterized by a sensitive monsoon system that is associated with marked natural precipitation variability. This region has been and is projected to be subject to substantial global and regional-scale changes including greenhouse-gas-induced warming and sea-level rise, land-use and land-cover change, and substantial biomass burning. We argue that more attention should be paid to rapidly increasing air pollution over the explosively growing cities of West Africa, as experiences from other regions suggest that this can alter regional climate through the influences of aerosols on clouds and radiation, and will also affect human health and food security. We need better observations and models to quantify the magnitude and characteristics of these impacts
