A citation and co-citation analysis of 10 years of KM theory and practices

In a previous issue of Knowledge Management Research & Practice (KMRP), we analysed the content and keywords of all articles published in the first decade of KMRP. With this article, we extend our preliminary analysis to the citation and co-citations made by these articles. The study covers all the 256 articles published. The most cited article was A dynamic theory of organisational knowledge creation by Nonaka. The most cited KMRP article was by Nonaka and Toyama: The knowledge-creating theory revisited: knowledge creation as a synthesizing process. The co-citation analysis of the 100 most cited articles in KMRP publications showed that four groups of topics emerged, one around communities and situated learning, the second group around networks, knowledge transfer and research methods, a third group around the foundations of knowledge management and a fourth group around intellectual capital.     

Body Image Phenomena and Measures of Physiological Performance

Abstract

This study was designed to investigate the relationships between three measures of body image and two measures of physiological performance. The Fisher-Cleveland Barrier Index, the Secord Homonym Test, and the Body Cathexis Questionnaire were correlated with dominant hand grip strength and the Michael-Gallon revision of the Harvard Step Test. Pearson's r was employed to determine the degree of relationship. Fifty males selected at random from general education classes at San Fernando Valley State College constituted the research sample. Of the six possible pairings only one reached statistical significance: the Homonym Test and grip strength (r = .33 at .05 level). It was concluded that a general relationship does not seem to exist between the measures of body image and physiological performance utilized in this study. These and other findings led the authors to re-examine several questions concerning the nature of body image phenomena.     

Investigation of blood pulse PPG signal regulation on toe effect of body posture and lower limb height

Objective: To study the regulation of blood pulse volume via photoplethysmography (PPG) signal detected from toe, while the lower limb is passively raised in different height positions. Methods: Use a modified non-invasive PPG technique to detect the blood pulse signal on toe with infrared (IR) photo sensor. A protocol consisting of two postures, i.e., supine and 45° reclining, was designed to conduct laboratory trial in this study. During the period of performing the protocol of these postures, the lower limb was passively raised from the heights of 10 cm to 60 cm randomly and individually with sponge blocks underneath the foot. Results: In the supine posture, the higher the foot was passively raised, the more the blood PPG signal decreased. In the 45° reclining posture, the blood PPG signal increased at the beginning and then decreased in the foot height position from 10 cm to 60 cm. In both postures the normalized AC signal changes significantly while the normalized DC signal changes little. Conclusion: The toe PPG signals can obviously indicate the regulated blood volume change with the designated postural procedures due to the heart level position.     

Community and Collectivism: the role of parents’ organisations in the education system

This paper outlines the theoretical and empirical starting‐points for a research project addressing the role of parents’ organisations in the education system. It argues that a study of relationships conducted between homes, schools and parents’ groups and organisations has the potential to illuminate key concepts in education, considering as examples ‘citizenship’ and ‘community’. The paper is divided into three main sections. The first briefly describes the study's background, its scope and methodology. The second section considers the use of some of Antonio Gramsci's work in providing a theoretical starting‐point with which to explore the construction and maintenance of hegemonic discourses surrounding parenting. The concluding section of the paper widens the discussion to consider two key concepts, community and citizenship. It is argued that the discursive positioning of these concepts, in other words, how they are understood and defined, influences the ways in which relationships between parents and the education system are perceived and construed. This is illustrated with reference to readings of'citizenship’ and ‘community’ which emphasise, not consensus and homogeneity as in traditional definitions, but conflict, difference and multiplicity. The paper concludes that there is a continued need for empirical data focusing on everyday citizen and citizen‐state interactions which reveal how individuals live within, and understand and experience these relationships.     

‘It’s the best thing I’ve done in a long while’: teenage mothers’ experiences of educational alternatives

Pregnant and mothering schoolgirls have been identified as an educationally vulnerable group. Many are not welcomed in their mainstream schools and as a consequence, access a range of educational alternatives. This article presents the views and experiences of 14 young women in the English Midlands, who became pregnant while still of statutory school age, 12 of whom spent time in alternative educational settings. It is based on data gathered from repeat interviews over an 18-month period and shows that all who attended the educational alternatives rated them highly and benefitted from what they had to offer. Using the concept of ‘difference’ as a central analytic theme, the article examines how and why this was the case. The analysis shows that it was through recognising some differences but not others that the educational alternatives were successful in supporting young women’s learning and well-being. Importantly, those that were recognised were done so in non-stigmatising ways. The research also highlights some limitations of the alternatives, alongside the ways in which gender and class continue to impact the educational outcomes and career trajectories of this particular group of students.     

Adverse childhood experiences and hallucinations

OBJECTIVE: Little information is available about the contribution of multiple adverse childhood experiences (ACEs) to the likelihood of reporting hallucinations. We used data from the ACE study to assess this relationship. METHODS: We conducted a survey about childhood abuse and household dysfunction while growing up, with questions about health behaviors and outcomes in adulthood, which was completed by 17,337 adult HMO members in order to assess the independent relationship of 8 adverse childhood experiences and the total number of ACEs (ACE score) to experiencing hallucinations. We used logistic regression to assess the relationship of the ACE score to self-reported hallucinations. RESULTS: We found a statistically significant and graded relationship between histories of childhood trauma and histories of hallucinations that was independent of a history of substance abuse. Compared to persons with 0 ACEs, those with 7 or more ACEs had a five-fold increase in the risk of reporting hallucinations. CONCLUSION: These findings suggest that a history of childhood trauma should be looked for among persons with a history of hallucinations.     

A Model for Inverting the Advanced Calculus Classroom

In this paper I discuss my experience in using the inverted classroom structure to teach a proof-based, upper level Advanced Calculus course. The structure of the inverted classroom model allows students to begin learning the new mathematics prior to the class meeting. By front-loading learning of new concepts, students can use valuable class time for exploring and solving complex problems, with the instructor available for guidance and assistance. This paper compares student performance in the inverted classroom with student performance in the direct instruction classroom. I also share student perceptions of the inverted classroom experience.     

Developing Children's Understanding of Fractions: An Intervention Study

Fractions constitute a stumbling block in mathematics education. To improve children's understanding of fractions, we designed an intervention based on learning‐by‐doing activities, which focused on the representation of the magnitude of fractions. Participants were 292 Grade 4 and 5 children. Half of the classes received experimental instruction, while the other half pursued their usual lessons. For 10 weeks, they played five different games using cards representing fractions (e.g., Memory and Blackjack). Wooden disks helped them represent and manipulate fractions while playing games. Our results showed an improvement in the conceptual understanding of fractions. The findings confirmed that the usual practice in teaching fractions is largely based on procedural knowledge and provides only minimal opportunities for children to conceptualize the meaning and magnitude of fractional notations. Furthermore, our results demonstrate that a short intervention inducing children to manipulate, compare, and evaluate fractions improves their ability to associate fractional notations with numerical magnitude.
