TL;DR: In this paper, the authors used the random stochastic frontier model to estimate the technical efficiency of Japanese airports, with regulation and heterogeneity included in the variables, and ranked the airports according to their productivity for the period 1987-2005.
Abstract: In this paper, the random stochastic frontier model is used to estimate the technical efficiency of Japanese airports, with regulation and heterogeneity included in the variables. The airports are ranked according to their productivity for the period 1987-2005 and homogeneous and heterogeneous variables in the cost function are disentangled. Policy implications are derived.

TL;DR: DSPERSE reduces the failure of content retrieval by five orders of magnitude compared to common CDN implementations, without significantly increasing content retrieval delay, and numerical results show that DISPERSE improves content availability by a factor of 1.3\times when deploying the minimum cost flow algorithm.
Abstract: This paper introduces DISPERSE, a distributed scalable architecture for delivery of content and services that provides resilience against node failure through location-independent storage and replication of content. Current content delivery networks (CDNs) have, at least to some degree, a centralized structure thus susceptible to a single point of failure. DISPERSE addresses this limitation by implementing a fully de-centralized structure. DISPERSE is a two-layer architecture: the first layer (front-end layer) exposes services (e.g., Web, SFTP) to clients; the second layer (back-end layer) provides reliable distributed storage of content and application state. Content in DISPERSE’s back-end layer is stored and exchanged as Named Data Network (NDN) content objects. This allows DISPERSE to implement fine-grained, location-independent, fully decentralized content replication mechanisms. We validate the performance of DISPERSE under two node failure scenarios. In the first scenario, content can be stored in any DISPERSE node, and all nodes are equally likely to fail. In this scenario, we use non-linear optimization techniques to determine the optimal number of content copies under availability and latency constraints. In the second scenario, different nodes fail with different probabilities, and content is stored in nodes according to its value, node failure probability, and resource availability. This scenario is addressed as an instance of the minimum cost flow problem. Our results show that DISPERSE reduces the failure of content retrieval by five orders of magnitude compared to common CDN implementations, without significantly increasing content retrieval delay. Further, numerical results show that DISPERSE improves content availability by a factor of $1.3\times - 2.3\times $ when deploying the minimum cost flow algorithm.

TL;DR: In this article, a method of class-formation based on multi attribute utility theory is proposed, which is taken into consideration students' preferences, and demonstrates the importance of classformation of optional subjects in education.
Abstract: ††† Summary This paper focuses on the importance that class-formation of optional subjects in school education can affect learners. And it will point out problems about conventionally 'mechanical' class-formation, and suggest a method of class-formation based on multi attribute utility theory, which is taken into consideration students' preferences. Therefore, this paper exercises experiments by a new method and a conventional one, and demonstrates its priority. This also constitutes a prototype-system.

TL;DR: In this article, a novel quantitative method is proposed to set bid-caps based on the residue demand analysis and the optimal bidding analysis of individual generators, which employs a discriminative framework for more efficient market regulation.
Abstract: Due to the oligopoly characteristics of power generation and the inelasticity of electric demand, a whole-sale electricity spot market needs a "benchmark regulation". A novel quantitative method is proposed in this paper to set bid-caps based on the residue demand analysis and the optimal bidding analysis of individual generators. The proposed method employs a discriminative framework for more efficient market regulation. The results of the case study demonstrate that the proposed method can prevent market power exercising while minimizing the interference with the market. The proposed bid-cap setting method is potentially useful for market power mitigation.

TL;DR: In this article, the authors examined technical efficiency of Portuguese pension funds management companies, using a stochastic frontier model in order to obtain estimates of economies of scale and scope, revealing a significant effect of efficiency measures on pension funds efficiency.
Abstract: This paper examines technical efficiency of Portuguese pension funds management companies, using a stochastic frontier model in order to obtain estimates of economies of scale and scope. The empirical findings reveal a significant effect of efficiency measures on pension funds efficiency. Their implications for managers and policy makers are discussed.
