凹资源配置问题的混合动态规划方法

Concave resource allocation problem is an integer programming problem of minimizing a nonincreasing concave function subject to a convex nondecreasing constraint and bounded integer variables. This class of problems are encountered in optimization models involving economies of scale. In this paper, a new hybrid dynamic programming method was proposed for solving concave resource allocation problems. A convex underestimating function was used to approximate the objective function and the resulting convex subproblem was solved with dynamic programming technique after transforming it into a 0-1 linear knapsack problem. To ensure the convergence, monotonicity and domain cut technique was employed to remove certain integer boxes and partition the revised domain into a union of integer boxes. Computational results were given to show the efficiency of the algorithm.     

Adaptive resource allocation algorithm for internet of things with bandwidth constraint

In order to improve the transmission accuracy and efficiency of sensing and actuating signals in Internet of Things(IoT) and ensure the system stability,an adaptive resource allocation algorithm is proposed,which dynamically assigns the network bandwidth and priority among components according to their signals’ frequency domain characteristics.A remote sensed and controlled unmanned ground vehicle(UGV) path tracking test-bed was developed and multiple UGV’s tracking error signals were measured in the simulation for performance evaluation.Results show that with the same network bandwidth constraints,the proposed algorithm can reduce the accumulated and maximum errors of UGV path tracking by over 60% compared with the conventional static algorithm.     

The microeconomics of the allocation of teachers' time and student learning

The authors use a microeconomic theory of schools and highly detailed panel data on time allocations to examine student learning curves for reading and mathematics. In addition to examining the factors that affect student achievement, they investigate the role teachers' values play in allocating scarce learning time to students, and the subsequent effects on the distribution of learning across those students. They test hypotheses about the productivity of teachers in teaching mathematics and reading, whether marginal products vary across a sample of teachers, and whether the marginal products of time in alternate types of classroom organization significantly differ. The authors' findings are consistent with the view that more time on a subject does increase learning, but suggest that the size of the effects is small and subject to diminishing returns. With respect to teacher preferences, the results show that teachers in the sample overwhelmingly employed compensating strategies in allocating resources to the students. Teachers tend to prefer narrower distributions of learning across students than wider ones.     

Optimal distributed resource allocation in a wireless sensor network for control systems

INTRODUCTION With the rapid development of wireless com-munication technology, the combination of wireless communication and control systems becomes a new trend of networked control systems. Among the kinds of wireless technologies, wireless sensor network (WSN) has attracted a lot of interest and visibility due to its huge application space. WSN is a kind of wire-less ad-hoc network which connects embedded sen-sors, actuators, and processors and in which each node consists of a wireles…     

Noisy chaotic neural network for resource allocation in high-speed train OFDMA system

High-speed train communication system is a typical high-mobility wireless communication network. Resource allocation problem has a great impact on the system performance. However, conventional resource allocation approaches in cellular network cannot be directly applied to this kind of special communication environment. A multidomain resource allocation strategy was proposed in the orthogonal frequency-division multiple access （OFDMA） of high-speed. By analyzing the effect of Doppler shift, sub-channels, antennas, time slots and power were jointly consid- ered to maximize the energy efficiency under the constraint of total transmission power. For the purpose of reducing the computational complexity, noisy chaotic neural network algorithm was used to solve the above optimization problem. Simulation results showed that the proposed resource allocation method had a better performance than the traditional strategy.

Funding, resource allocation, and performance in higher education systems

This article analyzes forms of resourceallocation in university systems and theireffects on performance in institutions ofhigher education. Internationally, highereducation systems differ substantially withregard to research and education fundingsources and to ways that resources areallocated. European universities receive themajority of their funding from public sources,but private funding plays a more important rolein Anglo-American systems of higher education.Many governments use competitive elements inthe process of allocating public funds toinstitutions of higher education. Examplesinclude the implementation of performancemeasures through formula funding, or resourceallocation on the basis of evaluated projectproposals. Corresponding forms ofperformance-based resource allocation can befound within most higher educationinstitutions. This article analyzes how variousforms of funding and resource allocation affectuniversities at the macro-level and individualbehavior at the micro-level. A theoreticalapproach to this problem suggests thatperformance-based funding tends to bring aboutpositive changes but is also a factor inunintended side effects. Forms of resourceallocation influence the behavior of academicsand managers in higher education, particularlytheir levels of activity as well as the kindsof activities they engage in and their ways ofdealing with risks. Empirical analyses partlyconfirm these hypotheses. It can be shown thatchanges in resource allocation have an impacton the level and type of activity academicsconcentrate on but not on the long-term successof universities.

Comparative efficacy of group and individual feedback in gross anatomy for promoting medical student professionalism

Professionalism is a core competency of medical training that requires students to develop the skills of providing and receiving feedback. Our study evaluated the effectiveness of delivering feedback in a group setting compared with an individual setting. The first‐year class of Mayo medical students (n = 49) enrolled in gross anatomy (in dissection teams), completed weekly anonymous evaluations of themselves and their teammates regarding seven aspects of professionalism (altruism, compassion, respect, honesty/integrity, responsibility, commitment to excellence, and self‐reflection). Professionalism scores from these surveys were calculated using a six‐point Likert scale. Students were also asked to comment on strengths and possible areas for improvement on each peer. At the midpoint of the course, peer comments and professionalism scores were shared with students in debriefing sessions either individually or with their team. Analysis of preintervention and postintervention professionalism scores indicated that the students receiving feedback in a one‐on‐one setting (student and instructor) were more likely to demonstrate higher scores on subsequent evaluations as compared with those students receiving feedback in a group setting (all team members and one instructor). Our findings suggest that providing feedback to first‐year medical students on an individual basis is the best way to improve professional attitudes and behaviors.

Effects of individual and cooperative computer-assisted instruction on student performance and attitudes

In this study, the performance and attitudes toward instruction of learners working individually on a computer-based sex education lesson were compared with those of learners working cooperatively in dyads. A tatal of 60 eighth-graders received treatments that either required individual work or encouraged cooperation with a partner. Results indicated that students who worked cooperatively significantly outperformed those who worked individually. On an attitude measure, interactions were detected between instructional method and gender, as well as among instructional method, gender, and ability. High-ability males and females reported comparable attitudes toward each instructional method, but ratings for low-ability students were differentiated according to instructional method: Low-ability males responded most favorably, while low-ability females responded least favorably to individualized methods, and low-ability females responded most favorably and low-ability males least favorably to cooperative methods.

Investigating the use of student perception data for teacher reflection and classroom improvement

This article reports a study involving: (1) developing and validating a learning environment instrument, (2) investigating whether reflection on feedback generated using the instrument led to improvements in the learning environment and (3) examining how teachers used the feedback. For the new learning environment instrument, validity was supported for a sample of 10,345 secondary students over 3 years (2,042 students in 2008, 4,467 in 2009 and 3,836 in 2010). To investigate whether reflection on feedback from this instrument led to improvements in the learning environment, multivariate analysis of variance and effect sizes were used to examine pre–post differences. Statistically significant improvements in students’ views of the learning environment were found for 8 of the 11 scales. Finally, we examined how teachers used the student feedback. Of the 459 teachers, 45 focus teachers used the feedback as part of a formal action research approach involving entries in reflective journals, written reports, discussions and participation at a forum. These data were analysed to provide an overview of the ways in which the information was used, and to provide a more detailed account of the journey of one of the teachers.
