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

Kristen Lucas  Patrice M. Buzzanell 《Journal of Applied Communication Research》2004,32(4):273-292

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.  相似文献

Intensity and physiological strain of competitive ultra-endurance exercise in humans     

Lucas SJ  Anglem N  Roberts WS  Anson JG  Palmer CD  Walker RJ  Cook CJ  Cotter JD 《Journal of sports sciences》2008,26(5):477-489

The aim of this study was to determine the magnitude and pattern of intensity, and physiological strain, of competitive exercise performed across several days, as in adventure racing. Data were obtained from three teams of four athletes (7 males, 5 females; mean age 36 years, s = 11; cycling .VO(2 peak) 53.9 ml . kg(-1) . min(-1), s = 6.3) in an international race (2003 Southern Traverse; 96 - 116 h). Heart rates (HR) averaged 64% (95% confidence interval: +/- 4%) of heart rate range [%HRR = (HR - HR(min))/(HR(max) - HR(min)) x 100] during the first 12 h of racing, fell to 41% (+/-4%) by 24 h, and remained so thereafter. The level and pattern of heart rate were similar across teams, despite one leading and one trailing all other teams. Core temperature remained between 36.0 and 39.2 degrees C despite widely varying thermal stress. Venous samples, obtained before, during, and after the race, revealed increased neutrophil, monocyte and lymphocyte concentrations (P < 0.01), and increased plasma volume (25 +/- 10%; P < 0.01) with a stable sodium concentration. Standardized exercise tests, performed pre and post race, showed little change in the heart rate-work rate relationship (P = 0.53), but a higher perception of effort post race (P < 0.01). These results provide the first comprehensive report of physiological strain associated with adventure racing.  相似文献

Shaping the Web: Why the Politics of Search Engines Matters   总被引：1，自引：0，他引：1  

Lucas D. Introna  Helen Nissenbaum 《The Information Society》2000,16(3):169-185

This article argues that search engines raise not merely technical issues but also political ones. Our study of search engines suggests that they systematically exclude (in some cases by design and in some, accidentally) certain sites and certain types of sites in favor of others, systematically giving prominence to some at the expense of others. We argue that such biases, which would lead to a narrowing of the Web's functioning in society, run counter to the basic architecture of the Web as well as to the values and ideals that have fueled widespread support for its growth and development. We consider ways of addressing the politics of search engines, raising doubts whether, in particular, the market mechanism could serve as an acceptable corrective.  相似文献

Persistence and withdrawal by students in a preservice science and mathematics teacher education course     

Mr. David F. Tulip  Dr. Keith B. Lucas 《Research in Science Education》1991,21(1):320-327

At a time when recruitment into preservice teacher education courses in mathematics and science is difficult, one strategy to increase the number of graduates is to minimise the number of students who fail to complete their university courses. This study sought to determine factors which distinguish withdrawers from persisters in the first semester of a B.Ed course. Discriminant analysis was employed; a discriminant function employing seven factors resulted in correct classification in 81% of cases. Further analysis distinguishing between dropouts and transferees resulted in two discriminant functions with some common variables. Specializations: Science Education, Pedagogy.
