Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
EFFECTS OF ETHNO-MATHEMATICS INSTRUCTIONAL APPROACH AND PROBLEM-BASED LEARNING STRATEGY ON STUDENTS’ INTEREST, ACHIEVEMENT AND RETENTION IN GEOMETRY IN BENUE STATE, NIGERIA
No full textThis study examined the effects of the Ethno-mathematics instructional approach and Problem-based learning strategy on students\u27 interest, achievement, and retention in geometry in Benue State, Nigeria. Quasi-experimental design involving pretest, posttest, and post-posttest with two experimental groups and one control group. Twelve research questions guided the study and twelve hypotheses were tested at 0.05 level of significance. The population comprised 20,213 Junior Secondary Two (JS II) students, with a sample of 1,200 students selected using simple random sampling. Two instruments were used for data collection namely; Geometry Interest Ratings Scale and Geometry Achievement Test. Content validity index for GIRS was 0.78 and construct validity for GAT was 0.88. The reliability of GIRS was tested using Cronbach Alpha formula which yielded an index of 0.81 and K-R21 was used to determine the reliability index of GAT which yielded an index of 0.75. Data were analyzed using mean and standard deviation for research questions and Analysis of Covariance (ANCOVA) for hypotheses The findings indicated a significant difference in the mean interest ratings of students taught geometry using the ethno-mathematics instructional approach, problem-based learning strategy, and conventional teaching approach. However, no significant difference was found in the mean interest scores between male and female students taught geometry using the ethnomathematics instructional approach or problem-based learning strategy. Additionally, there was a significant difference in the mean achievement and retention scores of students taught geometry using these approaches compared to the conventional teaching approach. No significant difference was found in the mean achievement or retention scores between male and female students taught using these approaches. The ANCOVA result on the interaction effect between methods and gender on retention indicates that there is no significant interaction effect between Ethno-mathematics instructional approach, Problem-based learning strategy and gender on retention. Based on the findings of this study, it is recommended that: Students should be subjected to consistent utilisation of ethno-mathematical operations within their culture, adoption of the ethno-mathematics instructional approach in the school system, and training of mathematics teachers in the use of ethno-mathematics instructional approach to improve students\u27 interest, achievement and retention in geometry
IMPACT OF FORENSIC ACCOUNTING ON FRAUD DETECTION IN NIGERIAN DEPOSIT MONEY BANKS
Full text linkThis study investigated the impact of forensic accounting on fraud detection in deposit money banks within Benue State, Nigeria, utilizing a cross-sectional research design. The population consisted of 145 employees from three deposit money banks operating in Makurdi Metropolis, Benue State. A census sampling technique was employed, and data were collected using a structured questionnaire validated through content and construct validity methods, achieving a Cronbach\u27s Alpha reliability coefficient of 0.872. The study employed binary logistic regression to estimate the impact of forensic accounting variables on fraud detection. The findings reveal that Engagement of Forensic Accountants (EFA) significantly enhances fraud detection, with a coefficient (B) of 1.671 (SE = 0.414), Wald statistic of 9.830 (p 0.001), and odds ratio (Exp(B)) of 3.911. This implies a 291.1 increase in the likelihood of fraud detection with the engagement of forensic accountants, underscoring their pivotal role in improving financial transparency and accountability. Conversely, Litigation Support Skills (LSA) did not show a statistically significant impact on fraud detection (B = 0.541, SE = 0.378, p = 0.152), suggesting limited effectiveness in this context. However, Forensic Investigative Professional Skills (FIS) demonstrated a significant positive impact (B = 1.203, SE = 0.406, p = 0.015), increasing the likelihood of detecting fraud by 104.4. The study recommends that banks prioritize the integration of forensic accountants into internal audit processes to bolster fraud detection capabilities effectively. Furthermore, continuous professional development in forensic investigative techniques should be emphasized to enhance staff skills and readiness in identifying and mitigating complex fraud schemes
Eco-friendly management of the flea beetle, Podagrica species (Coleoptera: Chrysomelidae) on okra (Abelmoschus esculentus (L.) Moench) with Artemisia annua L. seed extract
Get PDF<p>Okra, grown and consumed in every ecological zone, is amongst the most sort after fruit vegetable crops in Nigeria. The crop is often infested by diverse field insect pests, especially the flea beetle Podagrica species, which impinges on its growth and productivity. The application of synthetic pesticides has been the generic insect pest control measure due to its touted effectiveness. These synthetics, however, has safety concerns which include; hazard to human health, amplification of toxins in the food chain, pest resurgence, domestic animals and human poisoning, environmental pollution, insect resistance, natural enemies destruction; springs, wells, rivers, and underground water contamination. Stakeholders are advocating an alternative management approach that is sustainable with less negative social and environmental impact. This study, therefore, compared the insecticidal efficacy of Artemisia annua (source of the antimalarial artemisinin) seed extract in comparison with Cypermethrin 10 EC, a synthetic insecticide, in controlling Podagrica species, the major field insect pests of okra. The trial was set out in a 7 x 4 factorial arrangement integrated into a randomized complete block design and replicated thrice. Cypermethrin 10 E.C was tested at 0.25 ml, 0.50 ml, and 0.70 ml/100 ml of water, while Artemisia annua extract was applied at 1.00 ml, 2.00 ml, and 3.00 ml/100 ml of water respectively. The control for both treatments was designated 0.0 ml. Data on leaf damage and flea beetle abundance were carried out from 4-10 weeks after planting (WAP) whilst the pods' weight was measured at maturity. The result shows that i) the concentrations of Artemisia extract and Cypermethrin sprayed provided comparable protection to okra against the flea beetle; ii) the yield of okra (pod weight) does not vary between Artemisia annua extract and Cypermethrin treated plots; and iii) flea beetle infestations vary with okra developmental stages.</p>

Full text linkThis study examined the effect of microfinance banks on the growth of selected small and medium scale enterprises in Makurdi Metropolis, Benue State.The study was anchored on Pecking Order theory. The researcher used both primary and secondary sources from a population of 960 and a sample of 282 respondents obtained by the use of a structured questionnaire. The data collected were analyzed using descriptive statistics such as frequency, simple percentage and the relationship between the variables of the model was tested using multiple linear regression analysis. The result of the regression analysis indicates that a positive relationship exist between Credit by Microfinance (CMF) Job Creation (JOC) of selected SMEs in Makurdi Metropolis and the relationship is statistically significant (p<0.05). A positive relationship exist between Credit by Microfinance and Business Expansion (BEX) of selected SMEs in Makurdi Metropolis and the relationship is statistically significant (p<0.05). A negative relationship exist between Savings Mobilization and the Growth of Small and Job Creation (JOC) of selected SMEs in Makurdi Metropolis and the relationship is not statistically significant (p>0.05). A positive relationship exist between Savings Mobilization (SMB) and Business Expansion (BEX) of selected SMEs in Makurdi Metropolis and the relationship is statistically significant (p<0.05). It was concluded that micro finance does enhance the job creation and expansion capacity of small business in Nigeria. It was recommended among others that microfinance bank should adopt similar strategies adopted by deposit money banks in deposit mobilization because it is by so doing that they will be able to grant quality loans to entrepreneurs which will lead to job creation in the economy

Full text linkThis study evaluated the effect of investment climate on Small and Medium Scale Enterprises growth in Makurdi Metropolis. The study was anchored on The Neoclassical Approach, Financial Growth Theory and Theory of diffusion of innovation. The researcher used both primary and secondary sources from a sample of 250 respondents obtained by the use of a well structured questionnaire from the study areas. The demographic data collected were analyzed using descriptive statistics such as frequency, simple percentage and the relationship between the variables of the study were analyzed using multiple linear regression analysis. The hypotheses of the study were tested using the probability value of the estimates. The result of the regression analysis indicates that a negative relationship exist between access to credit (ACTC) and Small and Medium Scale Enterprises growth in Makurdi Metropolis Nigeria (SGT) and the relationship is not statistically significant (p>0.05) and not in line with a priori expectation. Power supply (PWSP) was positively related to Small and Medium Scale Enterprises Growth in Makurdi Metropolis Nigeria (SGT) and the relationship is statistically significant (p<0.05) and in line with a priori expectation. A positive relationship exist between Information and Communication Technology (ICT) and Small and Medium Scale Enterprises Growth in Makurdi Metropolis Nigeria (SGT) and the relationship is statistically significant (p<0.05) and in line with a priori expectation. It was concluded that for this growth to be achieved, the climate of investment must be addressed and made favourable for business start-up and growth. It was recommended that government should effectively regulate the power sector as there are still lingering challenges with billings, tariffs and metering processes after privatization. To ameliorate the problem faced by SMEs in the study area, government can create hubs for SMEs in the study area and provide them with adequate electricity or develop renewable energy such as solar energy to improve entrepreneurs\u27 access and growth.
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
