The Ex-post Evaluation of Investments in Accounting Information System: The Role of Content, Context and Process (Published)
Investments in Accounting Information System (AIS) play an important supporting role in most sectors of the economy. This study was designed to answer the question related to the roles of contextual factors, namely «content », « context» and « process» on the ex-post evaluation of investments in information technology. The model was tested using survey data collected from 269 companies. The results of analyzing structural equation support the proposed model and highlights positive and significant relationship of AIS investment and business performance of the companies. The same the analysis multiple groups also show the important moderating role of «content» , «context» and «process» on the relationship between AIS investments and business performance.
Effect of Size on Proximate Composition and Heavy Metal Content of the Mangrove Oyster Crassostrea gasar from the Andoni River, Nigeria (Published)
The proximate composition and heavy metal content of the mangrove oyster Crassostrea gasar from the Andoni River was investigated. Samples were categorized into three class sizes: small (< 25 mm), medium (25-50 mm), and large (> 50 mm) each with 10 sampling units for each class size. Differences across class size were significant for carbohydrate, lipid, and fiber content with their highest mean values recorded as 58.39 ± 0.21%, 6.70 ± 0.10% and 18.22 ± 0.28% respectively. Size-specific differences were detected only for concentrations of lead and zinc which showed maximum concentrations of 0.53 ± 0.02μg/g and 42.69 ± 1.81μg/g respectively. The proximate composition and heavy metal content recorded were generally higher in large-sized oysters and the variations observed were attributed to obvious differences in their class sizes. The remarkably low moisture content recorded in C. gasar was attributed to higher drying temperatures (105°C). Food quality and uptake of heavy metals in tissues of C. gasar generally varied along size gradients, with peak values in large-sized individuals. However, the levels of heavy metals recorded in soft tissues of C. gasar in this study were generally very low and fall within levels expected in tissues of aquatic biota.
Content Knowledge Of Social Studies Teachers In Senior High Schools In The Sekondi-Takoradi Metropolis In The Western Region Of Ghana (Review Completed - Accepted)
The main objective of the study was to investigate SHS Social Studies teachers’ understanding of the content of what they teach to be able to achieve the objectives of the subject. To achieve this objective, interview guide, observation checklist and questionnaire were used to elicit the views of respondents. In all, 54 Social Studies teachers were involved in the study. The simple random, cluster and convenient sampling techniques were used to select the respondents for the study. Frequency counts and percentages were used as statistical tools for analysing the questionnaire data collected, and the data from the interview guide was transcribed, categorized, analysed and discussed on themes and subthemes that emerged. The findings revealed that majority of the teachers lack content knowledge of Social Studies and they were not teaching to develop attitude, skills, values and knowledge. Teachers were teaching the subject in as amalgamation of social sciences and are thus not making students to be reflective, concerned and participatory citizens. Based upon the findings, it was recommended largely that there should be more courses on Social Studies content mounted and studied in all teacher training institutions in the country to help teachers develop the needed content knowledge about the subject to enhance effective teaching
