A Research Review of Nurse Teachers’ Competencies

The conceptions of what constitutes nursing competence and how such competence is taught and learned are changing, due to rapid changes in in the health sector. Nurse teachers’ competencies for providing high-quality, up-to-date nursing education, are developing accordingly. This paper reviews the existing research on nurse teachers’ competencies and addresses how this research identifies, describes, and conceptualizes these competencies. A rigorous search, retrieval and appraisal process identified 25 relevant studies for inclusion in the review. A thematic synthesis was applied to the findings of the studies and subsequent themes were synthesized. The thematic synthesis of the empirical evidence resulted in the five broad themes: academic, nursing, and pedagogical competencies; attitudes; management and digital technology. However, these separate elements appeared to be highly integrated. Hence, this paper indicates that nurse teachers’ competencies may be assessed using a holistic approach, which could bring together the disparate attributes required for successful professional performance in specific situations.     

KDD: The challenge to individualism

KDD (Knowledge Discovery in Databases) confronts us withphenomena that can intuitively be grasped as highly problematic, but arenevertheless difficult to understand and articulate. Many of theseproblems have to do with what I call the ``deindividualization of theperson': a tendency of judging and treating persons on the basis ofgroup characteristics instead of on their own individual characteristicsand merits. This tendency will be one of the consequences of theproduction and use of group profiles with the help of KDD. Currentprivacy law and regulations, as well as current ethical theoryconcerning privacy, start from too narrow a definition of ``personaldata' to capture these problems. In this paper, I introduce the notionof ``categorical privacy' as a starting point for a possible remedy forthe failures of the current conceptions of privacy. I discuss some waysin which the problems relating to group profiles definitely cannot besolved and I suggest a possible way out of these problems. Finally, Isuggest that it may take us a step forward if we would begin to questionthe predominance of privacy norms in the social debate on informationtechnologies and if we would be prepared to introduce normativeprinciples other than privacy rules for the assessment of newinformation technologies. If we do not succeed in articulating theproblems relating to KDD clearly, one day we may find ourselves in asituation where KDD appears to have undermined the methodic andnormative individualism which pervades the mainstream of morality andmoral theory.     

What underlies successful word problem solving? A path analysis in sixth grade students

Two component skills are thought to be necessary for successful word problem solving: (1) the production of visual-schematic representations and (2) the derivation of the correct relations between the solution-relevant elements from the text base. The first component skill is grounded in the visual–spatial domain, and presumed to be influenced by spatial ability, whereas the latter is seated in the linguistic–semantic domain, and presumed to be influenced by reading comprehension. These component skills as well as their underlying basic abilities are examined in 128 sixth grade students through path analysis. The results of the path analysis showed that both component skills and their underlying basic abilities explained 49% of students’ word problem solving performance. Furthermore, spatial ability and reading comprehension both had a direct and an indirect relation (via the component skills) with word problem solving performance. These results contribute to the development of instruction methods that help students using these components while solving word problems.     

The relationships between pelvic range of motion,step width and performance during an athletic sprint start

ABSTRACT

The aims of this study were (a) to describe the kinematics underlying the phenomenon of the knee of the swing leg passing medially in front of the athlete during the single push (SP) phase of the block sprint start, and (b) to determine the relationships between block phase pelvis range of motion (RoM), 1^st step width and block phase performance. Three-dimensional kinematic data (250 Hz) were collected from eleven competitive sprinters (100 m PB: 11.17 ± 0.41) performing maximal effort block starts. The joint angles of the rear hip with respect to the pelvis and the pelvis segment angles with respect to the laboratory coordinate system were calculated during the block start phase to the end of the 1^st stance. A combination of pelvis list and rotation (not hip adduction) was coupled with the thigh of the swing leg moving medially during the SP phase. A very high positive correlation was found between pelvic list RoM and 1^st step width (r = 0.799, p = 0.003). No other significant correlations were found. Attempting to reduce pelvic RoM or changing frontal and transverse plane hip joint angles to minimise medial thigh motion is unlikely to lead to an improvement to performance.
