Purpose: The purpose of this paper is to examine perceived and factual realities of open access predators and further delve into usage patterns of predatory open access journals (OAJs) by researchers and its implication on quality assurance in Library and Information Science Research. It also investigates factors promoting use of these outlets, as well as authors’ perspectives on quality control for OAJs. Design/methodology/approach: The paper reviewed available literature on OAJs and the proliferation of predatory journals. It also presents author’s viewpoint on the implication of using predatory journals for Library and Information Science Research in Nigeria. Findings: The number of predatory publishers globally has grown rapidly from 18 in 2011 to 693 in 2015, whereas standalone journals increased from 126 to 507 in 2015. Library and information science (LIS) studies were published in some of the listed predatory journals by Jeffrey Beall, and this has reduced global recognition of LIS researchers in Nigeria. Upcoming authors were easily attracted to publishing their work in predatory journals because of fast review process, prompt publishing and quest for global visibility. Checking against plagiarism, ensuring quality control, increased awareness for non-use of predatory journals were some of the recommendations given. Practical implications: It is clear that if LIS educators report their research in predatory OA outlets, individual and institutional reputation will be affected which may eventually lead to low ranking status of institutions. Nigerian universities low ranking status by several indices can be traced to the nonappearance or low scholarly literature published in reputable and respected journal outlets. Scholars with less quality studies will not be invited to feature as reviewers and international panelist in reputable thematic conferences and meetings neither can they be invited as external examiners in universities abroad. Originality/value: This work is very valuable in evaluating the growth of predatory journals in Library and information Science Research in Nigeria. It provides distinctive ways to evaluating OAJs and how to identify and avoid predatory journals. © 2017, © Emerald Publishing Limited.

Stress plays an important role in drug- and addiction-related behaviours. However, the mechanisms underlying these behavioural responses are still poorly understood. In the light of recent reports that show consistent regulation of many genes encoding stress proteins including heat shock proteins following ethanol exposure in Drosophila, it was hypothesised that transition to alcohol dependence may involve the dysregulation of the circuits that mediate behavioural responses to stressors. Thus, behavioural genetic methodologies were used to investigate the role of the Drosophila hsp26 gene, a small heat shock protein coding gene which is induced in response to various stresses, in the development of rapid tolerance to ethanol sedation. Rapid tolerance was quantified as the percentage difference in the mean sedation times between the second and first ethanol exposure. Two independently isolated P-element mutations near the hsp26 gene eliminated the capacity for tolerance. In addition, RNAi-mediated functional knockdown of hsp26 expression in the glial cells and the whole nervous system also caused a defect in tolerance development. The rapid tolerance phenotype of the hsp26 mutants was rescued by the expression of the wild-type hsp26 gene in the nervous system. None of these manipulations of the hsp26 gene caused changes in the rate of ethanol absorption. Hsp26 genes are evolutionary conserved, thus the role of hsp26 in ethanol tolerance may present a new direction for research into alcohol dependency. © the author(s).

The effects of space weather on ground based technology mostly occur due to the varying geomagnetic field during geomagnetic storms, producing geomagnetically induced current (GIC). Space weather storms involve intense and rapidly varying electric currents in the ionosphere, which create geoelectric and geomagnetic fields at the Earth's surface. In this study we have investigated some intense geomagnetic storms: September 18th, 2000; March 31th, 2001; October 21st, 2001; November 6th and 24th, 2001; October 29th and 31st, 2003 and November 9th, 2004. The electric field for each day has been computed using ground conductivity and geomagnetic recordings. The conductivity models are determined by least square fit between the observed and predicted GIC values. Our results show that GIC are strongly correlated with the geoelectric field, and also with eastward and westward auroral electrojet indices and time derivatives of the horizontal geomagnetic field. Root mean square error statistical test has been employed to evaluate the accuracy of the models used. ©2012 IACS.


The food habits and school feeding programme of pupils in a rural community in Odogbolu local government area of Ogun State, Nigeria was assessed in this study. A total of 68 pupils from primaries I to III in both public and private primary schools were involved in the study. It was found that majority of the school children had three meals daily. Majority of the pupils do not bring food to school from home. The amount of money brought to school to purchase mid-day meal foods was higher with pupils from private school than those from public schools. However, generally the quantity and quality of the mid-day meal purchased on both schools were poor and therefore did not have significant contribution of their nutritional status. © Asian Network for Scientific Information, 2010.

The effect of four herbicides (atrazine, primeextra, paraquat and glyphosate) on soil microbial population, soil organic matter and dehydrogenase activity was assessed over a period of six weeks. Soil samples from cassava farms were treated with herbicides at company recommended rates. Soil dehydrogenase activity was measured at four-day sampling intervals up to the 20th day. Bacterial, fungal and actinomycetes populations decreased upon treatment with herbicides when compared to the control. There was significant reduction in percentage organic matter after the herbicides were applied to soils. Soil organic matter then increased after continuous application from the second to the sixth week of treatment. Herbicide treatment resulted in a significant drop in dehydrogenase activity when compared to the control soil samples. Obtained results indicated that soils treated with primeextra had the lowest dehydrogenase activity of 16.09 μg (g-1min-1) after the sixth week of treatment, while soils treated with glyphosate had the highest dehydrogenase activity of 20.16 μg (g-1min-1) when compared to other herbicides used for treatment. Dehydrogenase activity increased from the second to the sixth week of treatment. This study indicated significant response of soil microbial activity to herbicide treatment and increased adaptation of the microbial community to the stress caused by increase in concentration of the herbicides over weeks of treatment. © 2011 Academic Journals.

This paper investigates the analytical study of the temperature fluid distribution in a one-dimensional fluid flow under a magnetic field. It studies the effect of internal heat generation on the entropy generation in an exothermic reactive hydromagnetic fluid flow under Arrhenius kinetics. The fluid is assumed to be incompressible and electrically conducting flowing steadily through a channel with isothermal wall temperature. The solution is obtained taking into account a supplementary term in energy equation due to internal heat generation using the traditional perturbation method. Thermo-physical aspects of the flow are presented and discussed.

Alcohol dependence is a complex disorder affecting all social and ethnic groups. Although the scientific understanding of the mechanism governing this multifactorial disease is still in its infancy, understanding its biological bases, including the potential contribution of genetic factors, is key to characterizing individual's risk and developing efficacious therapeutic target to combat the disease. This review provides an overview of different approaches that are being increasingly integrated to extend our knowledge of the genetic underpinnings of alcohol dependence. © 2013 Taylor & Francis Group, LLC.

Filth-feeding and breeding, non-biting synanthropic flies have been incriminated in the dissemination of human enteropathogens in the environment. This study determined the species of non-biting synanthropic flies associated with four filthy sites in Ilishan, Ogun State, southwest Nigeria, and assessed their potentials for mechanical transmission of human intestinal parasites. 7190 flies identified as Musca domestica (33.94%), Chrysomya megacephala (26.01%), Musca sorbens (23.23%), Lucilia cuprina (8.76%), Calliphora vicina (4.59%), Sarcophaga sp. (2.78%) and Fannia scalaris (0.70%) were examined for human intestinal parasites by the formol-ether concentration and modified Ziehl-Neelsen techniques. Eggs of the following parasites: Ascaris lumbricoides (34.08%), Trichuris trichiura (25.87%), hookworms (20.45%), Taenia sp. (2.36%), Hymenolepis nana (1.11%), Enterobius vermicularis (0.56%), Strongyloides stercoralis (larvae; 3.89%) and cysts of Entamoeba histolytica/dispar (27.26%), Entamoeba coli (22.67%), Giardia lamblia (3.34%) and Cryptosporidium sp. (1.81%) were isolated from the body surfaces and or gut contents of 75.24% of 719 pooled fly batches. The helminths A. lumbricoides and T. trichiura and the protozoans, E. histolytica/dispar and E. coli were the dominant parasites detected, both on body surfaces and in the gut contents of flies. C. megacephala was the highest carrier of parasites (diversity and number). More parasites were isolated from the gut than from body surfaces (P < 0.05). Flies from soiled ground often carried more parasites than those from abattoir, garbage or open-air market. Synanthropic fly species identified in this study can be of potential epidemiological importance as mechanical transmitters of human intestinal parasites acquired naturally from filth and carried on their body surfaces and or in the gut, because of their vagility and feeding mechanisms. © 2012 Elsevier Ltd.

Background: This study was aimed at examining the potential of non-biting synanthropic filth flies to acquire naturally eggs of human intestinal helminths from unsanitary sites, and its attendant public health importance. Methods: Body surface washings and gut contents of flies caught foraging while infected human faeces lay exposed at a garbage dump in Iperu, Ogun State, Nigeria and within 24 hours subsequently after removal of faeces from the dump were examined parasitologically by the formol-ether concentration technique. The viability of helminth eggs isolated from flies was determined by incubation under laboratory conditions. Results: A total of 303 flies were examined: Musca domestica (107; 35.3%), Chrysomya megacephala (125; 41.3%) and Musca sorbens (71; 23.4%). Eggs of Ascaris lumbricoides and Trichuris trichiura isolated from exposed human faeces were recovered from the body surfaces and or gut contents of flies caught before (141; 77.5%) and after removal of exposed faeces (44; 36.4%). Eggs of Taenia sp. were isolated only from the gut contents of three C. megacephala flies caught after removal of exposed faeces. Significantly more (p<0.05) eggs were recovered from fly gut contents than body surfaces and from flies caught before than after removal of exposed faeces. 93.1% (552; from exposed faeces) and 57.4% (408; from flies) of A. lumbricoides and T. trichiura eggs were viable. Conclusions: Synanthropic flies may, because they carry viable eggs acquired naturally from unsanitary sites, be involved in the epidemiology of human intestinal helminthiases. © The Author 2013.

This work investigated an interrelationship between the monthly means of time derivatives of horizontal geomagnetic field, dH/dt, sunspot number, Rz, and aa index for the period of substorms (from -90 to -1800 nT) during the years 1990-2009. A total of 232 substorms were identified during the period of study. The time derivative of horizontal geomagnetic field, dH/dt, used as a proxy for geomagnetically induced current (GIC) exhibited high positive correlation with sunspot number (0. 86) and aa index (0. 8998). The obtained geomagnetic activity is in 92. 665% explicable by the combined effect of sunspot number and aa index. The distribution of substorms as a function of years gives a strong support for the existence of geomagnetic activity increases, which implies that as the sunspot number increases the base level of geomagnetic activity increases too. © 2012 Versita Warsaw and Springer-Verlag Wien.
