Abstract This paper examines the factors that cause universities to undertake academic change, specifically, changes to achieve more effective teaching and learning. Based on an analysis of 30 reform‐oriented US colleges and universities, it suggests that universities respond to diverse environmental pressures, not solely to external mandates. There is evidence, too, that internal forces within universities can be an impetus for change. 相似文献

In 2007, Swedish authorities introduced open publication of comparisons of students' results at the end of compulsory school. In this study, we investigated a municipality that had succeeded in breaking a negative trend from a bottom position in the ranking in 2007 to a top position in 2010, apparently through inclusive practices. The purpose of this study is to examine and isolate key elements that make a difference in schools and classrooms in the work with all students. Data were collected through interviews and classroom observations. Mary Douglas' cultural–cognitive perspective of institutional theory and the work of Ludwik Fleck are used to identify and analyse factors of importance to the increased goal fulfilment. The school's decision to end all segregated small group activities and to include all children in the normal classroom activity is examined. Moreover, the emphasis on teachers’ reading and discussing of national and international research and focusing on all children's right to succeed in the classroom is analysed. The analysis suggests that focusing on goal fulfilment through inclusion gave a wider definition to the concept of successful schooling and changed the traditional thought style of the school. 相似文献

The paper explores the application of thermodynamic formalism to model and control transportation networks. Specifically, by considering the vehicles as the abstract energy supplied to the system, we show in certain circumstances that certain thermodynamic concepts such as temperature, thermal capacity and thermal equilibrium can have the corresponding notions in transportation context. In addition, despite the lack of a natural principle in transportation context that corresponds to the second law of thermodynamic as we will show, the most important thermodynamic notion, which is the entropy, can be also defined in order to measure the disorder of transportation systems. It is then shown that the state when all lanes have the same occupancy corresponds to the thermal equilibrium arising in isolated thermodynamic system. This equilibrium occupancy leads to a minimum entropy corresponding to a minimal disorder. Besides, by taking the transportation entropy as the storage function, a robust dissipativity based control strategy is presented to reduce the disorder and render the system better organized. Finally, an example is worked out to illustrate the results. 相似文献

Within the undergraduate mathematics curriculum, the topic of simple least-squares linear regression is often first encountered in multi-variable calculus where the line of best fit is obtained by using partial derivatives to find the slope and y-intercept of the line that minimizes the residual sum of squares. A markedly different approach from linear algebra, which could also be introduced in multi-variable calculus, obtains the regression line by vector projection. The latter viewpoint offers elegant proof of the equation relating the total, explained and unexplained variations. Consideration of data with the same regression line and correlation opens the door for a “mini-research experience” (MRE). A sequel MRE gives rise to an open Research Experience for Undergraduates topic to analyze reflection sequences and a fundamental connection between complex analysis and regression analysis. A few general guidelines and basic goals for MREs are included for those whose main interest is in undergraduate research. 相似文献

Hardwoods and softwoods were used side by side throughout Egyptian history, and importing softwoods that had an attractive color and texture was common. Over the decades, artifacts based on hardwoods and softwoods underwent deterioration phenomena, sometimes reaching either a level of brittleness or turning into a wood powder that may easily crumble. These levels of decay/degradation are often difficult to handle in terms of conservation treatments. To study or identify the reasons for decay has always been a point of interest for conservation purposes, but to assess decay and choose an appropriate treatment according to the state of preservation for the sake of keeping an artifact intact has become a subject of major importance. It is difficult at times to understand the deterioration process, because hardwoods and softwoods are different in structure, properties, and chemical composition. For this preliminary study, decayed samples from three commonly used softwood types, cypress (Cupressus sp.), cedar (Cedrus sp.), and pine (Pinus sp.), were identified and chosen. Scanning electron microscopy (SEM) of the samples indicated the degree of decay. Decayed and non-aged samples of the same wood type were analyzed using Fourier transform infrared spectroscopy (FTIR), and all the major carbohydrate and lignin bands were recorded. The strong hydrogen bonded (O–H) stretching absorption associated with water linked by hydrogen bonds to the –OH groups of cellulose and hemicelluloses in all decayed samples increased with decay. The brown powdery, fragile samples that had been evidently affected by microbial decay had a higher amount of lignin. The lignin/carbohydrate ratio was calculated and results compared. The increase of either lignin percentage or extractives in some of the samples had caused a darkening of color in both cypress and cedar samples, but the pine sample did not have the same texture and appearance. In cases where the lignin percentage decreased the samples had changed to a slightly lighter color. FTIR results explained the decay phenomena observed in SEM micrographs and helped assess wood decay and also confirmed results that had been previously obtained while applying traditional chemical analysis on wood. 相似文献

Through semi‐structured interviews, this study explored 11 bilingual school psychologists’ (BSPs) consultation experiences with teachers of English learners (EL) to determine referral concerns, recommendations made, challenges encountered, preparation experiences, and skills most needed. The most common referral issue concerned students’ academic performance and teachers’ attempts to parse out language acquisition difficulties from learning problems. Principal consultation challenges included the scarcity of trained professionals, teacher bias, and the stress of competing school priorities. BSPs relied most on their interpersonal skills and relationship building skills, as well as their knowledge of EL‐focused interventions and their problem identification skills. Recommendations to their monolingual school psychology colleagues included the need to actively seek out a) language and culture resources, b) relevant professional development opportunities, and c) consultations with fellow BSPs. Study limitations and implications are discussed. 相似文献

Most studies of parent–child bookreading have focused on mothers reading to their children. Though the role of fathers in children's lives is widely emphasized, we know almost nothing about father–child bookreading, particularly among low-income families. The present study was designed to examine how often low-income fathers report reading to their children and what the predictors and effects of paternal bookreading are. The fathers in this study were participants in the national evaluation of Early Head Start (EHS) and were recruited via mothers enrolled in the EHS study. Participating fathers were interviewed at home and their children's cognitive and language development were assessed using standardized measures from ages 2 to 5. Results demonstrated a wide variety in frequency of bookreading among fathers. Fathers were more likely to read to their children frequently if they spoke English at home, if they had a high school education, and if their children had better language skills. Fathers’ bookreading predicted children's cognitive outcome. Paternal bookreading did predict children's language outcomes but only for children whose fathers had at least a high school education. 相似文献
