PREVALENCE OF HALLUX ABDUCTO VALGUS AMONG VARIOUS GROUPS IN ANAMBRA STATE OF NIGERIA; Predominio de hallux abducto valgus entre varios grupos en el estado de anambra de Nigeria
No full textHallux Abducto Valgus is characterized by lateral deviation of the proximal phalanx of the hallux, medial deviation of the first metatarsal bone, and subluxation of the first metartasophalangeal joint. The objective of this study was to determine the prevalence of hallux abducto valgus among residents of Anambra State of Nigeria. The study was a cross sectional descriptive study, using a structured questionnaire. It was conducted among male and female subjects in the following occupational groups: Farmers, Traders, Medical student, Nursing student, Road Safety Corps, Police and the Military. A total of 1033 subjects within the age range of 15 to 74 years were studied. Hallux abducto valgus was identified by inspection of the foot. Prevalence of hallux abducto valgus in the study population was 12.9%. Hallux abducto valgus was more prevalent in males (14.3%) than in females (11.2%). Bilateral affectation of hallux abducto valgus (5.5%) was more prevalent than unilateral affectation (Right – 2.6%, left – 4.7%). Prevalence of hallux abducto valgus increased with increment in age. The prevalence of hallux abducto valgus among various occupational groups include: Police (18.0%), Road Safety Corps (16.7%), Nursing students (10%), Military (20%), Medical students (9.9%), Traders (8.3%) and farmers (17.0%). The prevalence of hallux abducto valgus in our study was 12.9%. The prevalence increased with increasing age and hallux abducto valgus was more prevalent in males than in females.

Assessing Entrepreneurship Education Pedagogies in Three Federal Colleges of Education in Nigeria’s South-South Geo-Political Zone
No full textThe study examines teaching and assessment methods used by vocational technical education teachers in teaching and assessing entrepreneurship education learning outcomes in Colleges of Education in the South-South Geo-political Zone of Nigeria. The study used survey research design. A census of entrepreneurship teachers conducted in the three Federal Colleges of Education in the South-South Geo-political zone yielded a population of 30 teachers. Structured questionnaire was the research instrument. Data were analyzed using SPSS. The findings show that teachers routinely use ineffective traditional teaching and assessment methods in entrepreneurship education instruction. Pedagogies that maximize entrepreneurial learning outcomes for achieving the self-employment objective of entrepreneurship education in Colleges of Education were recommended
Ultrasonographic study of the incidence of pyramidal lobe and agenesis of the thyroid isthmus in Nnewi population
No full textIntroduction: Ultrasound is the most reliable imaging modality for thyroid evaluation
due to the limitations in the clinical examination of this gland. Thyroid gland developmental anomalies are rare. Most of its variations are due to the persistence of the thyroglossal duct and the absence of the isthmus. The aim of this study was to determine
the incidence of pyramidal lobe and agenesis of the thyroid isthmus in Nnewi population using ultrasound. Materials and method: A total of 321 subjects resident in Nnewi,
including 167 males and 154 females, were randomized. A written consent was obtained from all patients. The subjects were aged between 18 and 35 years. This was
a prospective cross-sectional study. Thyroid glands were scanned using a 2-dimensional
ultrasound machine with a 7.5 MHz transducer; model Siemens Sonoline Prima which
was made in Japan for Siemens Medical System Incorporated, ultrasound Group, Issaquah, WA, 98029-7002, USA. Results: The study revealed no incidence of pyramidal lobe
and agenesis of the thyroid isthmus in the study population. Conclusion: This study has
clearly demonstrated no incidence of pyramidal lobe and agenesis of the thyroid isthmus
in subjects resident in Nnewi, Nigeria
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
