Acceptance and Adoption of Open Access Publication (OAP) in University Libraries in South East Nigeria

This study examines the kinds of open access scholarly publication or information resources accepted and adopted by federal university libraries in South East Nigeria. The purpose was to determine the factors that affect open access scholarly publication or information resources acceptance and adoption in university libraries. The study adopted descriptive survey research design. Findings revealed that university libraries accepts and adopts open access such as  institutional repository, open journals, subject repository, e-books, personal websites among others with the use of computers, internet facilities and services among others. Inadequate internet facilities and services were identified as a major factor that affects open access acceptance and adoption in university libraries. The study concluded that open access scholarly communication or information resources are vital tool of solving not only financial problems in libraries in general and university libraries in particular but also enable university libraries to keep pace with information explosion or changing trends in libraries. Based on this, it recommends that university libraries should ensure that users are provided with adequate and quality open access information resources for there is a need for access and use of information materials in all formats and acceptance and adoption of open access information resources could incite users to quickly access and utilize university library resources to a high extent.

The threat of revolution can play a pivotal role in spurring democratisation

Revolution itself brings seismic political changes to whichever country it takes place in. But what of the threat of revolution? The theory that it does is well-established, and Toke S. Aidt, Gabriel Leon, Raphael Franck, Peter S. Jensen provide further evidence in support of the claim here here

Perceived Influence of Copyright Act 2004 on the provision of Information Services in selected Law Libraries in Universities in North Central, Nigeria.

ABSTRACT This study investigated the influence of Copyright Act, 2004 on the provision of information resources in academic law libraries in North Central Nigeria. Three (3) objectives with corresponding resaerch questions guided the study while hypothesis was formulated. Descriptive survey research design was adopted for the study. The study surveyed 303 respondents (comprising 13 staff (Law library staff} and 290 law students{500 level undergraduate law students). The sample was drawn across five(5) law libraries in universities in North Centra, Nigeria. Questionnaire was used as instrument for data collection for the study. Descriptive statistical tools such as tables, frequencies and percentages were employed for data presentation and analysis, while chi-square statistic was used for the test of hypothesis at 0.05 level of significance. Findings of the study revealed that selected law libraries in universities in North Central Nigeria are aware of the provisions of the Copyright Act, 2004. Findings also revealed that the copyright Act 2004 has significant perceived influence on the provision of information services in selected academic law libraries in universities in North Central, Nigeria. However, findings indicated that, there is partial observance and enforcement of the provisions of the Act in the law libraries. This largely is as a result of some of the challenges identified during the cause of the study. These challenges as indicated by the study include: lack of proper organization of right owners in various aspects of intellectual property industry, lack of legal education on implication of intellectual property, lack of professional specialization in the practice of intellectual property, globalization and technology, dynamic nature of intellectual property, poor judicial sympathy and difficulty in negotiating licensing agreement for online databases. The study finally, made recommendations based on the findings

Relación de la calidad educativa con el desempeño laboral de los docentes militares de la Escuela de Artillería – 2017, Visión docente

El objetivo de la presente investigación fue determinar de qué manera se relaciona la calidad educativa con el desempeño laboral de los docentes de la Escuela de Artillería del Ejército – 2017. Visión docente. El enfoque fue de una investigación cuantitativa, de tipo descriptivo correlacional, de diseño no experimental. La población la constituye 30 docentes de la Escuela, y la muestra fue censal, a quienes se les aplicó una encuesta de 18 preguntas con una escala de cinco categorías de respuestas referida a ambas variables. Este instrumento tuvo una alta confiabilidad de 0.905. Se realizó el análisis correspondiente a los resultados de la encuesta llegando a la demostración empírica de que un 83.8% apoya o considera positivamente los requerimientos de los indicadores y las dimensiones propuestas en el instrumento; esto fue ampliamente corroborado y contrastado empleando el chi cuadrado. Se concluyó que la calidad educativa se relaciona directamente con el desempeño laboral de los docentes en la Escuela de Artillería del Ejército – 2017.Universidad Nacional de Educación Enrique Guzmán y Valle.Tesi

Nucleosynthetic Yields from "Collapsars"

The "collapsar" engine for gamma-ray bursts invokes as its energy source the failure of a normal supernova and the formation of a black hole. Here we present the results of the first three-dimensional simulation of the collapse of a massive star down to a black hole, including the subsequent accretion and explosion. The explosion differs significantly from the axisymmetric scenario obtained in two-dimensional simulations; this has important consequences for the nucleosynthetic yields. We compare the nucleosynthetic yields to those of hypernovae. Calculating yields from three-dimensional explosions requires new strategies in post-process nucleosynthesis; we discuss NuGrid's plan for three-dimensional yields.Comment: To appear in the Conference Proceedings for the "10th Symposium on Nuclei in the Cosmos (NIC X)", July 27 - August 1 2008, Mackinack Island, Michigan, US

Difficulties in Probing Nuclear Physics: A Study of 44^{44}Ti and 56^{56}Ni

The nucleosynthetic yield from a supernova explosion depends upon a variety of effects: progenitor evolution, explosion process, details of the nuclear network, and nuclear rates. Especially in studies of integrated stellar yields, simplifications reduce these uncertainties. But nature is much more complex, and to actually study nuclear rates, we will have to understand the full, complex set of processes involved in nucleosynthesis. Here we discuss a few of these complexities and detail how the NuGrid collaboration will address them.Comment: To appear in the Conference Proceedings for the "10th Symposium on Nuclei in the Cosmos (NIC X)", July 27 - August 1 2008, Mackinack Island, Michigan, US

Nucleosynthesis Calculations from Core-Collapse Supernovae

We review some of the uncertainties in calculating nucleosynthetic yields, focusing on the explosion mechanism. Current yield calculations tend to either use a piston, energy injection, or enhancement of neutrino opacities to drive an explosion. We show that the energy injection, or more accurately, an entropy injection mechanism is best-suited to mimic our current understanding of the convection-enhanced supernova engine. The enhanced neutrino-opacity technique is in qualitative disagreement with simulations of core-collapse supernovae and will likely produce errors in the yields. But piston-driven explosions are the most discrepant. Piston-driven explosion severely underestimate the amount of fallback, leading to order-of-magnitude errors in the yields of heavy elements. To obtain yields accurate to the factor of a few level, we must use entropy or energy injection and this has become the NuGrid collaboration approach.Comment: To appear in the Conference Proceedings for the "10th Symposium on Nuclei in the Cosmos (NIC X)", July 27 - August 1 2008, Mackinack Island, Michigan, US

Complete nucleosynthesis calculations for low-mass stars from NuGrid

Many nucleosynthesis and mixing processes of low-mass stars as they evolve from the Main Sequence to the thermal-pulse Asymptotic Giant Branch phase (TP-AGB) are well understood (although of course important physics components, e.g. rotation, magnetic fields, gravity wave mixing, remain poorly known). Nevertheless, in the last years presolar grain measurements with high resolution have presented new puzzling problems and strong constraints on nucleosynthesis processes in stars. The goal of the NuGrid collaboration is to present uniform yields for a large range of masses and metallicities, including low$-$mass stars and massive stars and their explosions. Here we present the first calculations of stellar evolution and high-resolution, post-processing simulations of an AGB star with an initial mass of 2 M_sun and solar-like metallicity (Z=0.01), based on the post-processing code PPN. In particular, we analyze the formation and evolution of the radiative 13C-pocket between the 17th TP and the 18th TP. The s-process nucleosynthesis profile of a sample of heavy isotopes is also discussed, before the next convective TP occurrence.Comment: To appear in the Conference Proceedings for the "10th Symposium on Nuclei in the Cosmos (NIC X)", July 27 - August 1 2008, Mackinack Island, Michigan, US
