TL;DR: The Varian approach as mentioned in this paper gives students tools they can use on exams, in the rest of their classes, and in their careers after graduation, and is still the most modern presentation of the subject.
Abstract: This best-selling text is still the most modern presentation of the subject. The Varian approach gives students tools they can use on exams, in the rest of their classes, and in their careers after graduation.

TL;DR: Simulation results show that the proposed utility-based radio resource management scheme is flexible and efficient for managing radio resources in mobile multimedia DS-CDMA environments.
Abstract: Radio resource management is one of the key ways for providing quality-of-service (QoS) to users in wireless networks. In this paper, we propose a utility-based radio resource management scheme for mobile multimedia DS-CDMA systems. The algorithm is aiming at the maximization of the system overall utilities. In order to reduce the computational complexity, the radio resource management is decomposed into two levels of subproblems. With the proposed algorithm, transmit power and data rate assigned to users are dynamically adjusted according to their QoS requirements, channel conditions and current system load, so that the optimal resource allocation is achieved. Simulation results show that our scheme is flexible and efficient for managing radio resources in mobile multimedia DS-CDMA environments.

TL;DR: It is hypothesized that search systems can benefit a great deal from having a set of transformations available, especially from a searcher point of view, and studied the effects that transformations may have, as well as the formal relation between transformations, resource space and resource base.
Abstract: generation, conversions between data resource types, etcetera. We hypothesize that search systems can benefit a great deal from having a set of transformations available, especially from a searcher point of view. Consider the following motivating example: Example 4.1.1 While on the road, a searcher uses his Pda to search the web for information on his stock. The Pda is equipped with software for reading pdf files and html files only. Using his favorite search engine he finds a spreadsheet. In this case it would be very useful if the search engine automatically transforms the spreadsheet to one of the formats which he can access on his Pda. Without such transformation the data resource would be completely useless at this point. In this case, the transformation can be said to be value adding. Even more, a broker that is capable of executing transformations on demand is considered to be value adding, as long as it executes “useful” transformations. We will get back to this discussion later. Transformations can have an effect on certain properties of data resources. In the given example, the transformation would have an effect on the data resource type. Other examples of effects would be: changing the resolution of an image, the document length, etcetera. The usefulness of a transformation thus depends on the effects that it has and the properties that the searcher desires. The remainder of this chapter is organized as follows. We will start by presenting a formal framework for transformations in Section 4.2. With this framework we specify what transformations are and how they behave. After that we extend this framework with complex transformations (such as composed transformations, or transformations on instances of complex types; see also Section 3.4.4) in Section 4.3. After that we study the effects that transformations may have, as well as present the formal relation between transformations, resource space and resource base. This is done in Section 4.4. Next, in Section 4.5, we will present some practical aspects that are relevant when implementing a system using such transformations. This includes aspects such as learning the effects of transformations and automatic transformation selection. Last but not least, we will present some experiments with transformations in Chapter 5. 4.2 Transformations Let TR be a set of transformations. The semantics of a transformation specify what this transformation actually does. The semantics of a transformation is given by the function:

TL;DR: In this paper, the authors analyzed the travel behavior of tourists holidaying on the island of Madeira, based on their type of air transport (scheduled airline flight, low-cost flight or charter flight).
Abstract: Transportation is an important topic in tourism research, since the tourist's journey to and from the destination is a fundamental component of the holiday. In island resorts, this issue assumes greater relevance as modes of transportation are limited. This paper analyses the travel behaviour of tourists holidaying on the island of Madeira, based on their type of air transport (scheduled airline flight, low-cost flight or charter flight). A trivariate probit model is used, taking into account the correlation between alternative transport types. The policy implications of the research findings, particularly those related to the management of tourist-based transportation modes, are discussed.

TL;DR: In this article, the authors examine the impact of dynamic pricing on consumer surplus and show that dynamic pricing is often win-win, with both firms and consumers being better off relative to the alternative of offering an optimal static price.
Abstract: Dynamic pricing is designed to increase profits by adjusting prices in respond to changes in the marginal value of capacity or changes in input costs. While thousands of papers have been written about dynamic pricing, this is to our knowledge the first paper to examine the impact of dynamic pricing on consumer surplus. Intuition suggests that dynamic pricing may be a zero-sum game, where additional profits are made by firms at the expense of reducing consumer surplus. Executives who subscribe to this hypothesis may be reluctant to implement dynamic pricing for fear of consumer backlash. In this paper, we show that dynamic pricing is often win-win, with both firms and consumers being better off relative to the alternative of offering an optimal static price. The intuition lies on the fact that for common demand functions, the surplus function is decreasing convex in price and so is the composite function that incorporates optimal prices as a function of cost.
