Blue-collar work,career, and success: occupational narratives of Sisu

This study examined underground iron ore miners' occupational narratives to uncover how their stories socialize miners into blue-collar careers and reinforce their work identities. Through the root theme of sisu (Finnish for inner determination), underground miners create a status hierarchy that is used to construct a sense of pride around their work and to establish milestones of success for themselves and others in their workgroup. Furthermore, they communicatively construct exemplars that guide their performance and decisions during the unfolding of their work experiences. Their discourses provide alternatives to white-collar conceptualizations and practices of careers and success.     

Write More,Grade Less: Five Practices for Effectively Grading Writing

This article describes five practices for effectively grading writing that demystify the grading process and focus on students, writing more and faculty grading less.     

Anticipatory contrast as a measure of time horizons in the rat: Some methodological determinants

In three experiments, the time horizon over which the rat evaluates alternative feeding sources was investigated. The time horizon was measured by the suppression of intake of one incentive (a 0.15% saccharin solution) when a preferred alternative incentive (a 32% sucrose solution) was available but delayed. In Experiment 1, we found a direct function between the amount of saccharin intake and the delay time before access to 32% sucrose. Compared with intake for a saccharin-only control, saccharin intake was suppressed before 4-min and 16-min sucrose delays, but not before a 32-min delay. Because previous work (Flaherty & Checke, 1982) had reported suppression before a delay of nearly 32 min, in the subsequent experiments we examined factors that might account for this difference. In Experiment 2, we found that saccharin intake was suppressed before a 32-min delay interval when saccharin and sucrose solutions were presented in a bright-novel test environment but not when the same solutions were presented in the home cage. In Experiment 3, we found that the time between testing and subsequent postsession feeding could also affect the suppression of saccharin intake. Saccharin intake was suppressed when access to 32% sucrose was delayed by 32 min and the test situation was followed by immediate postsession feeding, but not when postsession feeding was delayed by 90 min. These results thus extend estimates of the rat’s time horizon to at least 32 min, but indicate that the effective time horizon can vary, depending on the test situation.     

Maintaining the reversibility of foldings: Making the ethics (politics) of information technology visible

This paper will address the question of the morality of technology. I believe this is an important question for our contemporary society in which technology, especially information technology, is increasingly becoming the default mode of social ordering. I want to suggest that the conventional manner of conceptualising the morality of technology is inadequate – even dangerous. The conventional view of technology is that technology represents technical means to achieve social ends. Thus, the moral problem of technology, from this perspective, is the way in which the given technical means are applied to particular (good or bad) social ends. In opposition to this I want to suggest that the assumed separation, of this approach, between technical means and social ends are inappropriate. It only serves to hide the most important political and ethical dimensions of technology. I want to suggest that the morality of technology is much more embedded and implicit than such a view would suggest. In order to critique this approach I will draw on phenomenology and the more recent work of Bruno Latour. With these intellectual resources in mind I will propose disclosive ethics as a way to make the morality of technology visible. I will give a brief account of this approach and show how it might guide our␣understanding of the ethics and politics of technology by considering two examples of contemporary information technology: search engines and plagiarism detection systems.     

School visits to zoos and museums: a missed educational opportunity?

Recent studies in exhibitions have begun to consider the cognitive content of the ‘dialogue’ between visitor and exhibit designer. Such studies have focused on the leisure visitor and not on organised school visits. The study reported here compares the conversational content of primary school and family visitors at the London Zoo and the Natural History Museum, London. The data show that there are common features to the children's interactions with animal exhibits and that the content of the conversations varies little between family groups and school groups both within an institution and between institutions. The lack of any marked distinction between school and family visitors strongly suggests that schools are failing to make effective use of the educational potential of zoos. Secondly, the findings of this study are important in pointing to the features of animal exhibits to which children, and their accompanying adults, attend. The data suggest that there is a gulf between the level of knowledge and understanding visitors bring to the exhibits and the message that the museums and zoos may wish to communicate. It is suggested that more successful education will only be achieved when museums and zoos give more credence to understanding what the visitor already does, or does not, know.     

Mathe mit der Matte – Verkörperlichtes Training basisnumerischer Kompetenzen

Basic numerical representations are seen as the building block for the successful development of more complex numerical and arithmetic competencies. Extending previous studies focusing on improving basic numerical representations by means of embodied training schemes, the current study focused on an embodied training of children’s place-value understanding. In this vein, 49 secondgraders were trained on solving a number line estimation task by stepping on different fields of a dance mat allowing for separate estimations of tens and units with more effort needed to step on the tens. In a partially randomized cross-over design, two control conditions were used to controll for training effects caused exclusively by the numerical content trained or the use of the dance mat. Interestingly, results revealed specific training effects after both the embodied and the control conditions. However, training effects were significantly more pronounced after the embodied training, thereby providing further evidence for the benefit of an embodied training of the place-value structure of the Arabic number system.     

The nature of scientific knowledge and student learning: Two longitudinal case studies

This study was designed to investigate the relationship between students' views of the nature of scientific knowledge and their own learning of physics, and the evolution of this relationship over time. Twenty-three students enrolled in a physics course that emphasised laboratory work and discussions about the nature of science. Over a 15-month period, an extensive data base was established including student essays and interviews regarding their views of the nature of science and teaching and learning of physics. As part of an extensive data generation, students read a book on the epistemology of physics, wrote reflective essays, and subsequently discussed the epistemology of physics in class. Two intensive case studies are used to illustrate our understanding of students' views over time. Changes in students' views concerning the nature of scientific knowledge and of the science teaching and learning process, which were not always complementary, are described with the aid of a model. The findings of this research have direct relevance to the planning and implementation of science courses in which the development of understandings of the nature of science is an objective.     

Evaluating Strategic Approaches to Competitive Displacement: The Case of the U.S. Newspaper Industry

The concept of competitive displacement is central to theories of media evolution, and the threat that the Internet has posed to printed newspapers provides an ongoing case study on the topic. In particular, this situation offers an opportunity to examine the strategic efforts of print newspapers to prevent competitive displacement, as well as the effectiveness of these strategies. This article addresses these issues through an analysis of a unique data set, constructed from 20 years of newspaper circulation data, as well as data on local market characteristics, newspaper staffing and content variety, and state-level Internet penetration. Specifically, this article examines whether, and to what extent, these competitive strategies impacted local print newspaper circulation trends over this 20-year time period. This analysis focuses on the following strategic responses: (a) newspapers’ launching of online versions (a diversification strategy within the language of media evolution literature); and (b) newspapers’ efforts to cover a greater variety of subject areas, as measured by the number of editors and special editorial sections produced. (The authors characterize these as a “mimicking” strategy from media evolution literature, as this strategy essentially represents an effort to simulate the much greater content variety that readers can find online). This article examines the relationships between these circulation, strategic, and Internet penetration variables over a 20-year time period, while also taking into account relevant characteristics of local newspaper markets.
