    It is important to develop and validate a competency-based instrument for assessing mechanical metalwork technology students in technical colleges in Enugu and Ebonyi states Nigeria. The study was guided by three specific purposes, three research questions and one null hypotheses that was tested at 0.05 level of significance. The study adopted instrumentation research design. The study was carried out in the Technical Colleges in Enugu and Ebonyi states Nigeria. The population for the study was 134, made up of the year two students of metalwork technology from the six Government approved technical colleges in Enugu and Ebonyi States. The sample size was 80, made up of year two students of metalwork from the three purposive sampled technical colleges in the states. The instrument for data collection were the Competency-based Instrument for Assessing Metalwork Student’s cognitive knowledge on machine operations, Competency-based Instrument for Assessing Metalwork Student’s psychomotor (manipulative) skills and Competency-based Instrument for Assessing Metalwork Student’s Attitude (affective) skills on machine operations. These make up the competency –based instrument for assessing Metalwork students on Machine Operations (CBIAMSMO). The instruments were developed based on the NBTE curriculum for metalwork technology and the reviewed literature. The instruments passed through factor analysis, face, content and construct validations in order to obtain all the relevant items for the study. The data were analyzed using factor analysis, and Analysis of variance (ANOVA) to answer the research questions and the hypothesis respectively. The findings of the study revealed that the competency-based instrument for assessing metalwork students in machine operations in Technical Colleges should involve the test of cognitive (knowledge), manipulative skills (process and product skills) and attitudinal skills (affective) to make the assessment to be valid and reliable. Based on the findings, it was recommended that National Business and Technical Examinations Board (NABTEB) and Metalwork Teachers should include the competency-based assessment instrument in the assessment of metalwork students of Technical Colleges to obtain a valid and reliable assessment for proper acquisition of skills and sustainable employment thereafter.Keywords: Mechanical, metalwork technology, competency –based assessmen

    [Excerpt] In this article I will look into some of the recent 3D digitization projects and highlight numerous technological and financial challenges that would be familiar to many small and medium sized archives. I will further propose jQuery Reel, an open source three-sixty player as a viable alternative to 3D modeling and discuss the workflow we employed at Marist Archives

    A Multi-Phase Anglo-Saxon Site in Ewelme

    Get PDF
    New evidence is presented for a middle Anglo-Saxon ‘productive’ site on hilly ground north-west of Ewelme in south Oxfordshire. Coins and other finds from metal-detecting activity suggest the existence of an eighth- to ninth-century meeting or trading point located close to the Icknield Way. Th is place takes on an added significance because of its proximity to an early Anglo-Saxon cemetery and probably a late Anglo-Saxon meeting place. Th e authors provide an initial assessment of the site, its likely chronological development and its relationship with wider Anglo-Saxon activity in the upper Thames region and beyond. Some suggestions are made about the implications of the existence of such a long-lasting or recurring centre of activity for early medieval inhabitants’ perceptions of landscape

    Fatimid metalwork

    Get PDF
    Metalwork in the Islamic world encompasses a large geographical area from Spain to India, over an enormous time-period with the earliest dynasty, the Rashidun Caliphate in 632 CE to the present. Islamic metalwork includes numerous categories of artisanship incorporating arms, armor, vessels, utensils, coins, jewelry, tools, scientific instruments, figurines and polycandela. The focus of this writing however will be to analyze the four categories of metal objects into which the vast bulk of Fatimid metalwork falls, namely vessels, utensils, figurines, lamps and polycandela

    The Intentional Destruction and Deposition of Bronze Age Metalwork in South West England

    Get PDF
    The intentional destruction of Bronze Age metalwork prior to deposition is frequently recognised within assemblages, but rarely forms the focus of study. Furthermore, most research focuses on why metalwork was deliberately destroyed without considering how this process was undertaken. This thesis therefore analyses how metalwork might have been intentionally damaged and uses this to better interpret why. The material properties of bronze are considered alongside past research into the use of different implements, before a series of experiments are presented that explore how one might best break a bronze object. A better understanding of the methods by which Bronze Age metalwork might become damaged means one can identify intentional damage over that sustained accidentally, through use or post-deposition. This culminates in a Damage Ranking System, which can be utilised to assess the likelihood that damage observed on archaeological specimens is the result of intent. The Damage Ranking System is applied to Bronze Age metalwork from South West England (i.e. Cornwall, Devon, Dorset and Somerset). The catalogue of metalwork from this region was recently updated, highlighting instances of deliberate destruction that would warrant further study (Knight et al. 2015). The present research builds on this catalogue and involved analysis of complete and damaged objects from across the study region and from throughout the Bronze Age. Approximately 1300 objects were handled and studied and set within the Damage Ranking System alongside a contextual analysis of the findspots. This allowed trends in damage and depositional practices to be observed, demonstrating increased intentional destruction throughout the Bronze Age. It is shown that the deliberate destruction of metalwork throughout the Bronze Age related to the construction of personhood and emphasised links with other regions of Bronze Age Europe. This research demonstrates a new approach to the material that has wide-reaching applications in future studies.Arts and Humanities Research Council, the South West and Wales Doctoral Partnershi

    Assessment of the Skills Possessed By the Teachers of Metalwork in the Use of Computer Numerically Controlled Machine Tools in Technical Colleges in Oyo State

    Get PDF
    The purpose of this study was to assess the skills possessed by the teachers of metalwork in the use of computer  numerically controlled machine tools in technical colleges in Oyo State. Three research questions and three null hypotheses tested at 0.05 level of significance guided the study. A survey research design was adopted for the study. The population for the study comprised of all the 35 metalwork teachers in the technical colleges in Oyo State. A structured questionnaire consisting of 41 items was used for data collection. Two experts from the Department of Vocational Teacher Education, University of Nigeria, Nsukka, and one expert from the Advanced Manufacturing Unit, Scientific Equipment Development Institute, Akuke, Enugu, face validated the instrument. The reliability co-efficience of the instrument was 0.86. Data collected were analyzed using mean and standard deviation for the research questions while t-test was used for testing the null hypotheses. It was found from the study that six skills were not possessed by metalwork teachers in the use of computer numerically controlled lathe and grinding machine, while seven skills were not possessed in using computer numerically controlled milling machine.  It was recommended that regular and systematic retraining should be organized for metalwork teachers who lack required skills in using these machines.

    Domestic competition and export performance of manufacturing firms in Côte d’Ivoire

    Get PDF
    Because of transportation costs, African manufacturing firms benefit from some market power on their domestic market, where they can charge a higher price than the export price, net of transportation cost. We present a simple theoretical model of an exporting firm that discriminates between the export and the domestic markets, where firms engage in Cournot competition. It is then shown that the impact of increased competition on export performance by the firms is ambiguous, and may be negative for a non trivial range of parameter values. Using survey data on Ivoirian firms, our empirical analysis gives some support to this prediction, showing that the probability of a firm exporting decreases with increased competition.
