This article introduces the concept of the carrying capacity of data (CCD), defined as an integrated, evaluative judgment of the credibility of specific data-based inferences, informed by quantitative and qualitative analyses, leavened by experience. The sequential process of evaluating the CCD is represented schematically by a framework that can guide data analysis and statistical inference, as well as pedagogy. Aspects of each phase are illustrated with examples. A key initial activity in empirical work is data scrutiny, comprising consideration of data provenance and characteristics, as well as data limitations in light of the context and purpose of the study.  Relevant auxiliary information can contribute to evaluating the CCD, as can sensitivity analyses conducted at the modeling stage. It is argued that early courses in statistical methods, and the textbooks they rely on, typically give little emphasis to, or omit entirely, discussion of the importance of data scrutiny in scientific research. This inattention and lack of guided, practical experience leaves students unprepared for the real world of empirical studies. Instructors should both cultivate in their students a true respect for data and engage them in authentic empirical research involving real data, rather than the context-free data to which they are usually exposed.

This study aims to determine the opinions of high school principals on their cultural intelligence levels, to determine the activities of these principals to increase their cultural intelligence levels, the advantages of their having a high level of cultural intelligence, the factors that prevent them from increasing their cultural intelligence levels, and their suggestions to increase their cultural intelligence levels. The data obtained from the interview forms were analyzed by the content analysis method. The findings were organized and presented under themes and sub-themes. The study group of the research consisted of 40 school principals working in Mersin central districts in the 2020-2021 academic years. According to the study results; most of the participants stated that they had a high level of cultural intelligence while some participants stated that they had a low level of cultural intelligence. Regarding the activities to increase their level of cultural intelligence, principals stated that they did activities such as increasing their knowledge, going abroad, and developing social relations. The principals expressed three different opinions on the advantages of having a high level of cultural intelligence: organizational advantages, professional advantages, and individual advantages. It was determined that factors preventing principals from increasing their cultural intelligence levels were factors unrelated to principal and factors related to principal. The principals expressed two different opinions on what could be done to increase their cultural intelligence levels: The things to be done by the superiors and the things to be done the principal.

The viva examination or ‘defence’ is a pivotal moment in a student’s or researcher’s career. It marks the conclusion of one stage and the beginning of another, whether during the study period or when competing for research funding. Unlike many other formal assessments, the viva is an oral performance. Its form may strongly depend on the domain of science or knowledge sector, on the university or even on faculty. The rituals of interaction between jurors and candidates may differ in many cultural contexts. Yet, the core elements of the defence are the debate, the use of evidence, and the justification for a statement or opinion delivered orally, are common to all. Accordingly, although a successful defence is about content, it is also about language and attitude. In academic education, there is insufficient preparation for this moment when one is in front of jurors, a commission, and even a wider audience. We draw on our combined experience in our own careers and in their coaching of students to present an analysis of the ‘viva’ process. Our findings may help candidates position themselves in the viva context and offer practical advice on how to prepare, define an attitude, and structure answers and responses in general.
