Qualitative and quantitative approaches provide alternative, but often incompatible means to answer design questions during the early formative and later summative evaluation phases of the human-system interface design process. Human factors practitioners and researchers should identify which approach best addresses their particular research needs. Nuclear control room studies, particularly those conducted for control room modernization efforts, pose unique challenges. Due to the challenge of sampling large numbers of operators, the interface improvement goals of a usability evaluation, and the limited resources available for study analyses, a traditional quantitative approach is often not feasible or reasonable. Qualitative data provides a more pragmatic means to address design questions early on during the formative stage of the evaluation. Quantitative data can also be useful to bolster the qualitative data by presenting the data in a simple and intuitive graphic to provide evidence for design choices. An example case study using this approach during a formative evaluation study of a turbine control system human-system interface is described in this paper.

The Cost

This study aims to find a comparison of the calculation of the cost of goods manufactured in the CV. Mitra Setia Blitar uses the company's method and uses the Job Order Costing (JOC) method. The method used in this study is quantitative. The types of data used are quantitative and qualitative. Quantitative data is in the form of map production cost data while qualitative data is in the form of information about map production process. The result of calculating the cost of production of the map between the two methods results in a difference of Rp. 306. Calculation using the company method is more expensive than using the Job Order Costing method. Calculation of cost of goods manufactured using the company method is Rp. 2,205,000, - or Rp. 2,205, - each unit. While using the Job Order Costing (JOC) method is Rp. 1,899,000, - or Rp 1,899, - each unit. So that the right method used in calculating the cost of production is the Job Order Costing (JOC) method

Factors Affecting

This study seeks to help fill an important gap in the literature by investigating factors that have facilitated the use of management accounting practices (MAPs) in Vietnam - a transitional economy. Data were collected from 220 medium-to-large enterprises. Follow-up interviews were conducted with 20 accounting heads/vice heads to obtain further information and clarification. The quantitative data collected was analyzed using both descriptive and inferential statistics (including t-tests and structural equation modeling), while the qualitative data was used to shed further light on the various relationships described by the quantitative analysis. This paper reveals that both decentralization and competition have a positive, significant influence on the use of new MAPs except for the old ones. Consequently, the use of MAPs has a positive, significant influence on enterprise performance.

Thinking Process

Writing, regarded as a thinking process enables language learners to explore and transform their ideas into words in accurate and appropriate ways. Although it has been taught from the Elementary school level up to the higher level of education, English teachers and students encounter various challenges. For students, they still get difficulties in writing a text even after being taught. For teachers, correcting students’ writing increases their workload. Therefore, how to reduce the load of teaching writing and to decrease students’ difficulties in writing have become important problem to solve. Through applying a technique in teaching writing, this research aimed to explore whether the application of peer review technique can improve students’ achievement in writing recount text. The method applied in this research was a classroom action research. The subject of the research was X-4 class SMA Negeri 21 Medan. The instruments of collecting the data were writing tasks as quantitative data while observation sheet, questionnaire sheet, diary notes and interview as qualitative data. The finding showed that Peer Review Technique gives contribution to improve students’ achievement in writing recount text. Keywords: Achievement, Writing, Recount Text, Peer Review Technique
