DNA, Inference, and Information

This paper assesses Sarkar's ([2003]) deflationary account ofgenetic information. On Sarkar's account, genes carry informationabout proteins because protein synthesis exemplifies what Sarkarcalls a ‘formal information system’. Furthermore,genes are informationally privileged over non-genetic factorsof development because only genes enter into arbitrary relationsto their products (in virtue of the alleged arbitrariness ofthe genetic code). I argue that the deflationary theory doesnot capture four essential features of the ordinary conceptof genetic information: intentionality, exclusiveness, asymmetry,and causal relevance. It is therefore further removed from whatis customarily meant by genetic information than Sarkar admits.Moreover, I argue that it is questionable whether the accountsucceeds in demonstrating that information is theoreticallyuseful in molecular genetics.

The role of corporate technology strategy and patent portfolios in low-, medium- and high-technology firms   总被引：2，自引：0，他引：2  

Ulrich Lichtenthaler 《Research Policy》2009,38(3):559-569

Previous research into technology strategies and patent portfolios has focused on high-technology firms, whereas low- and medium-technology companies have been relatively neglected. Therefore, we analyze how corporate technology strategy and the size and composition of patent portfolios affect the performance of low-, medium- and high-technology firms. Data from 136 European companies are used to examine four hypotheses relating financial performance to technological diversification, technological aggressiveness, patent portfolio size, and patent portfolio quality. The cross-industry sample allows analyzing the different consequences of these strategic parameters in low-, medium- and high-technology firms by considering technological intensity as a moderator. Our first finding is that the positive impact of technological aggressiveness is limited in low- and medium-technology companies. Secondly, technological diversification has a positive effect in high-technology firms and a negative effect in low-technology firms. Thirdly, patent portfolio size has a positive effect only in high-technology firms. Finally, patent portfolio quality has an equally positive influence on all firms’ performance. In part, these results conflict with the findings of previous research into high-technology companies, and they call for rethinking the role of technology strategies and intellectual property portfolios in firms across industries.  相似文献   

Technological innovations and sectoral change: Transformative capacity, adaptability, patterns of change: An analytical framework   总被引：1，自引：0，他引：1  

Ulrich Dolata   《Research Policy》2009,38(6):1066-1076

Following up on recent debates about sectoral systems of innovation and production, the paper introduces a heuristic framework for analyzing and explaining distinct patterns of technology-based sectoral change. The concept is based on two interrelated influencing factors. The first is the sectoral-specific transformative capacity of new technologies themselves, that is, their substantial or incremental impact on socioeconomic and institutional change in a given sectoral system. The second is the sectoral adaptability of socioeconomic structures, institutions, and actors confronted with the opportunities presented by new technologies. The first factor—the sectoral transformative capacity of new technologies—enables us to identify the technology-based pressure to change and adjust the structural, institutional, and organizational architectures of the sectoral system. The second, complementary factor—sectoral adaptability—helps us to discern the distinct social patterns of anticipating and adopting this technology-based pressure. The specific interplay between the two influencing factors creates distinguishable modes of sectoral transformation, ranging from anticipative and smooth adjustments to reactive and crisis-ridden patterns of change. Even processes of radical sectoral change continue over longer periods of mismatch and are characterized by numerous and mostly gradual organizational, structural and institutional transformations.  相似文献

Analgesics use in competitive triathletes: its relationship to doping and on predicting its usage     

Pavel Dietz  Robert Dalaker  Stephan Letzel  Rolf Ulrich  Perikles Simon 《Journal of sports sciences》2016,34(20):1965-1969

The two major objectives of this study were (i) to assess variables that predict the use of analgesics in competitive athletes and (ii) to test whether the use of analgesics is associated with the use of doping. A questionnaire primarily addressing the use of analgesics and doping was distributed among 2,997 triathletes. Binary logistic regression analysis was performed to predict the use of analgesics. Moreover, the randomised response technique (RRT) was used to estimate the prevalence of doping in order to assess whether users of analgesics have a higher potential risk for doping than non-users. Statistical power analyses were performed to determine sample size. The bootstrap method was used to assess the statistical significance of the prevalence difference for doping between users and non-users of analgesics. Four variables from a pool of 16 variables were identified that predict the use of analgesics. These were: “version of questionnaire (English)”, “gender (female)”, “behaviour in case of pain (continue training)”, and “hours of training per week (>12 h/week)”. The 12-month prevalence estimate for the use of doping substances (overall estimate 13.0%) was significantly higher in athletes that used analgesics (20.4%) than in those athletes who did not use analgesics (12.4%). The results of this study revealed that athletes who use analgesics prior to competition may be especially prone to using doping substances. The predictors of analgesic use found in the study may be of importance to prepare education material and prevention models against the misuse of drugs in athletes.  相似文献

Teachers' goal orientations for teaching: Associations with instructional practices,interest in teaching,and burnout     

Jan Retelsdorf  Ruth Butler  Lilian Streblow  Ulrich Schiefele 《Learning and Instruction》2010,20(1):30-46

Two studies (one longitudinal) were designed to extend Butler's model of teachers' goal orientations for teaching. In Study 1, results from 281 teachers in Germany confirmed the predicted four-factor model comprising mastery, ability-approach, ability-avoidance, and work-avoidance goal orientations. As expected, mastery orientation and work avoidance emerged as positive and negative predictors, respectively, of adaptive patterns of instruction (mastery-oriented practices and cognitive stimulation) and high interest in teaching and low burnout; associations for both ability orientations were less consistent. In Study 2, 69 Israeli teachers completed the measures of instructional practices, interest in teaching and burnout several months after reporting their goal orientations. Results were very similar to those of Study 1. The two studies confirm that research on teachers' goal orientation is promising and has implications for understanding how teacher motivation might influence both teachers and their students.  相似文献

Students’ emotions during homework in mathematics: Testing a theoretical model of antecedents and achievement outcomes     

Swantje Dettmers  Ulrich TrautweinOliver Lüdtke  Thomas Goetz  Anne C. FrenzelReinhard Pekrun 《Contemporary educational psychology》2011,36(1):25-35

The experience of pleasant and unpleasant emotions in academic situations is known to affect students’ learning. The aim of the present study was to extend previous research by examining the antecedents and consequences of student emotions in the homework context. Multilevel analyses of a longitudinal dataset containing 3483 grade 9 and grade 10 students in 155 classes showed that the perceived quality of the homework tasks assigned by the teacher affected students’ experience of unpleasant homework-related emotions. Moreover, the experience of unpleasant emotions during homework sessions was negatively related to homework effort and negatively predicted later achievement in mathematics.  相似文献
