Governance for system optimization and system change: The case of urban waste     

Markus M. Bugge  Arne Martin Fevolden  Antje Klitkou 《Research Policy》2019,48(4):1076-1090

This paper analyses urban waste systems to explore how local authorities can resolve challenges related to climate change, urbanization and resource depletion. The paper investigates how different public governance regimes affect local authorities’ ability to move upwards in the waste hierarchy. It identifies three different governance regimes – traditional bureaucracy, new public management and networked governance – and uses the insights from innovation in urban waste in three Norwegian city regions – Oslo, Drammen and Bergen – to illuminate how these regimes possess both strengths and weaknesses in how they affect system optimization and system change. The observed working practices signal that the issue of urban waste systems is perceived as a challenge of system optimization rather than system change. Viewing this as a challenge requiring system change would probably have ensured a stronger directionality and a broader anchoring of actors. Such an approach is likely to have arrived at a waste prevention mode earlier than the step-by-step-solutions implemented so far. The paper concludes that there is not one best governance regime, but a need to acknowledge their co-existence and carefully consider the characteristics of the respective regimes in order to arrange urban waste systems for long-term dynamic and sustainable city regions.  相似文献   

Motivation counteracts fatigue-induced performance decrements in soccer passing performance     

Jeroen C.M. Barte  Arne Nieuwenhuys  Sabine A.E. Geurts  Michiel A.J. Kompier 《Journal of sports sciences》2019,37(10):1189-1196

Recent theories suggest that negative effects of fatigue on performance are determined by perception of effort and motivation rather than being directly caused by reaching physiological limits. In the current experiment, the influence of motivation on fatigue-induced decrements in soccer performance was experimentally investigated. Sixty amateur soccer players performed a validated soccer-passing test before and after a fatigue protocol. Results showed that players’ motivation and performance decreased after the fatigue protocol for players in the control group. In contrast, players in the motivation group (i.e., with motivation experimentally induced after the fatigue protocol) were able to uphold their motivation and increase their performance. These results indicate that motivation plays a crucial role in performance under fatigue, as fatigue-induced decrements in soccer passing performance can be counteracted by high levels of motivation. Future research may explore the limits of this counteracting effect and extend findings to other relevant performance aspects.  相似文献   

Effects of memory load on word recognition: Are there dual-routers in Norway?     

Lervåg  Arne  Bråten  Ivar 《Reading and writing》2002,15(3-4):233-259

The release-from-competition (RFC) effect, inwhich a difficult concurrent memory task speedspronunciation of low-frequency irregular wordsbut slows pronunciation of other word types,has been interpreted as strong support for thedual-route approach to word recognition. However, attempts to replicate this effect havenot produced consistent results. Besides,attempts at replication have mostly beenlimited to skilled readers of English. Thepresent research attempted to replicate the RFCeffect with mature normal readers of Norwegianand thus tested the generalizability ofdual-route models to a considerably moreshallow orthography than English. There was noevidence that the RFC effect reliably occurredamong Norwegian readers in this study, not evenamong certain selected readers who were seen ascandidates for possessing a dual-routearchitecture and suffering within thatarchitecture the kind of competition in naminglow-frequency irregular words that RFC issupposed to eliminate. Thus, it was notpossible to extend the applicability of adual-route approach to word recognition to therelatively shallow Norwegian orthography, andthe question of the architectural organizationof Norwegian readers was essentially leftunanswered by our data.  相似文献

Spot Reduction of Subcutaneous Adipose Tissue     

Arne L. Olson  Elliott Edelstein 《Research quarterly for exercise and sport》2013,84(3):647-652

Abstract

This study was designed to determine if the skinfold measurements on an exercised arm would decrease as a result of regular weight training with that arm. Thirty-two subjects completed three sets of 7-RM curls and three sets of 7-RM triceps extensions on either a daily or an alternate day schedule for a period of 6 weeks. The nonexercised arm was measured to establish the specificity of the spot reduction on the exercised arm. The results indicate that hard exercise in a specific area of the arm will result in a reduction of the subcutaneous adipose tissue in that area.  相似文献   

Innovating strategically in information and knowledge management: Applications of organizational behavior theory     

Tor J. Larsen  Johan Olaisen 《International Journal of Information Management》2013

A business school declares its strategy as becoming a leading European institution. As main vehicle for achieving recognition is the implementation of a top-down strategy naming five academic fields as key – (a) finance, (b) economics, (c) marketing, (d) law, accounting, and auditing, and (e) organizational behavior (OB). Top management allocates resources for research, academic activities, and positions to these five strategically chosen areas. Academic areas that are not strategically named must generate their own income through educational programs and research grants. Can OB serve as the platform to ensure the survival of IS/KMS? In our analysis, we found no other business school formulating a strategy along these lines; dominating strategic themes are internationalization, research excellence, and student environment. No academic field is singled out as strategic. We argue that selecting a few academic areas as a strategy is dysfunctional. We also found that OB is not very actively employed in research, be it positioning, theory, research model, analysis, or discussion. Hence, we do not find that OB offers any theorizing help to IS/KMS – this in contrast to innovation and change theories, for which we propose an framework as a means of defining IS/KMS research projects.  相似文献   

How Mathematical Knowledge for Teaching May Profit from the Study of History of Mathematics     

Reidar Mosvold  Arne Jakobsen  Uffe Thomas Jankvist 《Science & Education》2014,23(1):47-60

In this theoretical article, we aim at theorizing the old statement that mathematics teachers might profit from studying the history of mathematics. We do this by drawing upon the theoretical framework of mathematical knowledge for teaching (MKT). A selection of international studies on the history and pedagogy of mathematics is used as starting points for discussing how the different domains of teachers’ MKT—to a larger or smaller degree—can profit from the history of mathematics.  相似文献

Some Reflections on Motivating Situations and Situational Teaching     

Arne Friemuth Petersen 《Scandinavian Journal of Educational Research》2013,57(3-4):267-278

Debates about the crisis of school teaching in the Western world have focused more on education as a state of the art and on psychological problems of either teachers or pupils than on situational features which are of importance for teaching and learning situations. In applying K. R. Popper's propensity theory and his idea of situational logic, a preliminary analysis of problem situations is attempted with the aim of identifying biopsychological situational elements in children's preschool life‐conditions that could be simulated at school in their first years thereby enabling them to draw upon already acquired knowledge and skills. Two principal ways of acquiring experience — one instructive, the other selective — are described and discussed in relation to learning, exploration and play. It is argued that, while selection procedures are found in exploration, play and the like, instruction procedures are most often used in teaching situations despite growing evidence that instruction learning is less motivating than learning by action and selection, as various experiences with situational teaching indicate.  相似文献   

Motivational Climates,Achievement Goals,and Physical Education Outcomes: A Longitudinal Test of Achievement Goal Theory     

Hallgeir Halvari  Knut Skjesol  Tor Egil Bagøien 《Scandinavian Journal of Educational Research》2013,57(1):79-104

The present research tested the longitudinal relations over a school‐year between motivational climates, achievement goals, and five physical education outcomes, namely intrinsic motivation, perceived competence, positive attitude, exertion, and attendance in physical education. The results showed that students’ mastery goals measured early in the school‐year (Time 1) predicted all five physical education outcomes one year later (Time 2), controlling for physical education outcomes at Time 1. Two structural equation change models of climates and goals were also tested: (1) change in mastery climate predicted positively change in mastery goals, which positively predicted physical education outcomes after one year; and (2) distinct performance climate sub‐factors, namely changes in normative praise and negative emotional tune, predicted positive changes in performance‐approach, and performance‐avoidance goals, respectively. In turn, change in performance‐approach goals predicted positively, and change in performance‐avoidance goals predicted negatively, the PE outcomes after one year.  相似文献
