Reflecting on the Debates and Action of Mixed Methods Adoption in Business Research: Why Postgraduate Researchers Should Start Thinking This Way (Published)
The purpose of this paper is to evaluate the philosophical arguments underpinning the choice of mixed method [MM] research design. However, the study concluded that mixing research methods in business research is important as it helps to strengthen findings and recommendations arising from a given research study. More so, we recommend for postgraduate researchers to rationalise their choice of mixing methods based on complementarities, research priority, purpose and the implementation of findings and not on the basis of philosophical ontology and epistemology. This has been found to be the reason underpinning the much-lauded arguments in the adoption of mix methods
Quantitative Analysis of Factors Affecting Manufacturing Workers Performance in Industry: Case Study of Plastic Companies in Eastern Nigeria, Using SPSS (Published)
This work investigates the quantitative analysis of some factors that affect the performance of manufacturing workers in industries in southern Eastern Nigeria. Experiments were designed, and conducted through the use of work measurements technique and Tests Studies. These selected specific factors (maintenance, equipment, Power/Energy, technology, safety and Training.) used for the study, were investigated using eighty-two manufacturing workers from thirteen manufacturing companies. Data were collected for analyses. The software used was SPSS. Software tools used for various analyses in the study are: statistics, correlation, multi linear regression, response surface regression and multi- co linearity diagnoses, while t – value, F- ratio, p – values and variance of inflation factors (VIF) were used to test the hypotheses. The various statistical analyses performed were presented, studied and interpreted. The correlation coefficients are positive and in descending order of maintenance, equipment, Power/Energy, technology, safety and Training. The coefficient of determination, R2 and the variance ratio (VR); and F- value and t –coefficient values were also determined for strong inference. Curves were generated to observe the behavioral patterns of the relationship between manufacturing workers’ factors influence on performance. Results showed that the identified factors affected the performance of manufacturing workers in the manufacturing industries, in such a manner that the Companies productivity is affected positively by some factors and negatively by some others. Therefore, in the general consideration, the factorial indices that predicted the manufacturing workers performance of the selected factors: motivation, power, safety, maintenance, training, equipment and technology are found to be 0.877, 0.48, 0.614, -1.36, 0.789, 1.421 and – 0.495 respectively. These factorial indices are valid in controlling problems arising from manufacturing industries.
The use of vocabulary learning strategies (VLS) by foreign language (FL) learners has been described as steps taken by learners to enrich their word growth which would eventually enable them to function effectively in English. Research has shown fruitful outcomes of VLS, supporting the significant role it has in effective vocabulary learning, but whether VLS prevents English as a Foreign Language (EFL) learners’ attrition of vocabulary knowledge has been under-researched. To help close this research gap, the current study attempted to shed more light on the role of VLS in memorisation of vocabulary, both word attrition and retention, of 41 Arabic learners of English before and after completion of a B.A. course. Questionnaires and semi-structured interviews were used to indicate patterns of VLS use. Vocabulary achievement tests were used to examine the attrition of receptive and productive knowledge of learned words. The results showed that the use of rote learning (repeating an English item with its Arabic translation) led to more attrition in receptive word knowledge, while note taking strategies (writing an English item with its synonym and definition) emerged as a positive predictor of learners’ retention in receptive and productive word knowledge. The findings have significant implications for adoption and teaching effective VLS that prevent or minimize vocabulary attrition by L2 learners.
