Rediscovering radiology: new technologies and remedial action at the worksite

This study contributes to social studies of imaging and visualization practices within scientific and medical settings. The focus is on practices in radiology, which are bound up with visual records known as radiographs. The study addresses work following the introduction of a new imaging technology, tomosynthesis. Since it was a novel technology, there was limited knowledge of how to correctly analyse tomosynthesis images. To address this problem, a collective review session was arranged. The purpose of the present study was to uncover the practical work that took place during that session and to show how, and on what basis, new methods, interpretations and understandings were being generated. The analysis displays how the diagnostic work on patients' bodies was grounded in two sets of technologically produced renderings. This shows how expertise is not simply a matter of providing correct explanations, but also involves discovery work in which visual renderings are made transparent. Furthermore, the results point to how the disciplinary knowledge is intertwined with timely actions, which in turn, partly rely on established practices of manipulating and comparing images. The embodied and situated reasoning that enabled radiologists to discern objects in the images thus display expertise as inherently practical and domain-specific.     

“My Mom Tells Me I Should Follow the Rules,That’s Why They Have Those Rules”: Perceptions of Parental Advice Giving Among Mexican-Heritage Adolescents

Relatively little research has examined the ways in which immigrant Latino parents can effectively support their adolescent children’s schooling. To address this gap, we conducted in-depth interviews with 32 Mexican-heritage 9th graders. Students identified parents’ advice giving as the most salient form of involvement. Parental advice emphasized the importance of persisting in school, avoiding hardship as experienced by parents, and exhibiting social competence in relationships with peers and teachers. Parental advice giving was transmitted most effectively in the context of parent–child closeness. The findings form a basis for fostering effective and sustainable parent–school partnerships.     

Comparative Effectiveness or Evidence-Based Medical Practice: “A Rose by Any Other Name…”

The goal of education and research in all disciplines is to develop critical thinking skills as a method for improving clinical decisionmaking. The emphasis on critical thinking is nothing new and can be traced back to ancient times when Socrates challenged his students to think about their knowledge, beliefs, and behaviors by interrogating them. It is widely known that Socrates would press his students until they could provide reasons and evidence to support their arguments and would dismiss those beliefs and decisions that could not be supported with evidence. Today, scientific critical analysis in medicine is termed evidence-based medical practice (EBMP), or comparative effective research.     

Aunts,Uncles—Nieces,Nephews: Kinship Relations Over the Lifespan

Aunts and uncles play special roles in the lives and education of nieces and nephews. They are among the first adults children meet other than parents and grandparents. They are often willing and able to fulfill roles that strengthen the relationship with a niece or nephew, especially if they have never married. The roots of the relationship, coupled with a shared history and comparable values may, as a result, provide the basis for generalized reciprocity of support as the aunt (uncle) ages.     

Agreed discoveries: students’ negotiations in a virtual laboratory experiment

This paper presents an analysis of the scientific reasoning of a dyad of secondary school students about the phenomenon of dissolution of gases in water as they work on this in a simulated laboratory experiment. A web-based virtual laboratory was developed to provide learners with the opportunity to examine the influence of physical factors on gas solubility in water. An evaluation process involving 180 students revealed that the concepts connected to the dissolution of gas in water caused problems for the students even after having experimented with the virtual laboratory. To investigate the nature of learners’ reasoning about the visualised events, 13 video-recorded groups of learners were analysed. This study follows the reasoning of one group that displayed a possibly productive way of solving the problem. The results address the students’ general difficulty of discovering something that they are conceptually unprepared for within the virtual laboratory. The analysis shows how the students eventually found a way out of their dilemma by making an analogy with other dissolving processes. In effect, the analysis elucidates some of the analytical work that had to be done by the participants when collaboratively negotiating a shared meaning of a scientific concept in concord with a given task and set of instructional materials. Implications for design might be to provide the learning material with explicit hints that enable students to connect to specific phenomena related to the one investigated concept. The findings show the usefulness of video analytic research, informed by CA and ethnomethodology. This analytical framework can support design processes and provide useful information, which might identify hurdles to learning a scientific concept by simulated events and pathways to overcome these hurdles.     

Re-educating the Body

Abstract

This article means to investigate the philosophical concept of human embodiment in relation to physical education. As human beings not only do we have a body that we can control, but we ‘are’ our body and live embodied in the world, as the German thinker, Helmuth Plessner, puts it in one of his many contributions to the philosophical anthropology of the twentieth century. Elaborating on this concept of human embodiment, the article explores a form of physical re-education that takes as its starting point this aspect of being in the body which has been and is still being underestimated even in the physical educational system. Re-educating the body in this aspect includes becoming more aware of the states, postures and expressions of the body so as to be able to remain connected to the body and to get to know oneself better as being in the body.     

‘To hold the subject’s territory’: the Swedish Association of Biology Teachers and two curricular reforms, 1960–1965

The aim of this article is to investigate and analyse the cultural boundaries of school biology, and to a certain extent the natural science subjects in general, in two Swedish curriculum reforms, from the viewpoint of the Swedish Association of Biology Teachers (ABT). Thomas Gieryn’s concept of boundary‐work is thus used in analysing how the ABT acted to ‘hold the subject’s territory’. The ABT had substantial influence on the content of the new biology curricula, although this was sometimes achieved after internal conflict and required support from other actors, especially university biologists. Upper secondary biology had the highest status and was seen as a science, related to modern biological research and curriculum development, particularly in the USA. Despite the efforts of the ABT boundary‐work was unsuccessful in respect of the timetable; the natural science subjects were reduced both at the lower and upper secondary level, in contrast to what happened in many other Western countries.     

Media Consumption and Public Connection: Toward a Typology of the Dispersed Citizen

This paper explores the nature and extent of citizens’ connection to public space through media consumption. It reports on a study of data from two qualitative sources: panel responses and individual in-depth interviews. The authors’ findings are, first, that people's media consumption and forms of public connection may be significantly constrained by limitations on their time—not just objectively, but also subjectively (their sense of lacking time to use media or pursue information). Second, such is the complexity of how people think about their public connection that research methodologies must be sensitive to the details of people's reflexivity, while enabling effective typologies of the positions people take up in thought and practice. Third, such research may reveal not a consensus, but instead a range of incompatible framings of whether public connection matters and how it can be achieved. Research should aim, therefore, not at a redefinition of something as unified as “civic culture,” but rather at tracking the hetereogeneity of the “dispersed citizen.”
