Minimizing fleet operating costs for a container transportation company
2006
Abstract This paper focuses on a fleet management problem that arises in container trucking industry. From the container transportation company perspective, the present and future operating costs to minimize can be divided in three components: the routing costs, the resource (i.e., driver and truck) assignment costs and the container repositioning costs (i.e., the costs of restoring a given container fleet distribution over the serviced territory, as requested by the shippers that own the containers). This real-world problem has been modeled as an integer programming problem. The proposed solution approach is based on the decomposition of this problem in three simpler sub-problems associate…
L'Europa. Il quadro di riferimento comunitario e le possibilità di co-pianificazione e co-programmazione
2009
Il Dipartimento Urbanistica dell'Assessorato al Territorio della Regione siciliana ha contribuito in questi ultimi anni, all’avvio del processo di innovazione delle politiche e delle pratiche di pianificazione territoriale regionale/provinciale avvalendosi delle sperimentazioni consentite nei diversi programmi di cooperazione territoriale comunitaria .. Fino ad oggi la complementarità tra i due servizi ha consentito di indagare le potenzialità del piano nel quadro delle politiche comunitarie prospettate dallo Schema di Sviluppo dello Spazio Europeo. Tali esperienze sono meglio sintetizzate nel contributo presente nel dvd allegato a questo volume. Molte sono le problematiche e le possibilità…
Designing empirical experiments to compare interactive multiobjective optimization methods
2022
Interactive multiobjective optimization methods operate iteratively so that a decision maker directs the solution process by providing preference information, and only solutions of interest are generated. These methods limit the amount of information considered in each iteration and support the decision maker in learning about the trade-offs. Many interactive methods have been developed, and they differ in technical aspects and the type of preference information used. Finding the most appropriate method for a problem to be solved is challenging, and supporting the selection is crucial. Published research lacks information on the conducted experiments’ specifics (e.g. questions asked), makin…
A Coding Scheme Development Methodology Using Grounded Theory for Qualitative Analysis of Pair Programming
2008
A number of quantitative studies of pair programming (the practice of two programmers working together using just one computer) have partially conflicting results. Qualitative studies are needed to explain what is really going on. We support such studies by taking a grounded theory (GT) approach for deriving a coding scheme for the objective conceptual description of specific pair programming sessions independent of a particular research goal. The present article explains why our initial attempts at using GT failed and describes how to avoid these difficulties by a predetermined perspective on the data, concept naming rules, an analysis results metamodel, and pair coding. These practices ma…
Are Virtues Shaped by National Cultures or Religions?
2012
The present paper examines the relative influence of religion and nation on conceptions of virtues. In a first study, conducted in the Netherlands, 926 respondents of different profession, age, sex, and religious background rank ordered a list of 15 virtues. A comparison of Dutch Muslims and non-Muslims showed a remarkably high resemblance in their ratings of virtues. Only faith was rated as being much more important by Muslims than by non-Muslims. In the second study, the influence of national cultures was examined. Adults (N = 795) from two culturally relatively similar countries, Germany and the Netherlands, and from Spain rated the same list of virtues. Crossnational differences between…
Game-Theoretic Approach to Hölder Regularity for PDEs Involving Eigenvalues of the Hessian
2021
AbstractWe prove a local Hölder estimate for any exponent $0<\delta <\frac {1}{2}$ 0 < δ < 1 2 for solutions of the dynamic programming principle $$ \begin{array}{@{}rcl@{}} u^{\varepsilon} (x) = \sum\limits_{j=1}^{n} \alpha_{j} \underset{\dim(S)=j}{\inf} \underset{|v|=1}{\underset{v\in S}{\sup}} \frac{u^{\varepsilon} (x + \varepsilon v) + u^{\varepsilon} (x - \varepsilon v)}{2} \end{array} $$ u ε ( x ) = ∑ j = 1 n α j inf dim ( S ) = j sup v ∈ S | v | = 1 u ε ( x + ε v ) + u ε ( x − ε v ) 2 with α1,αn > 0 and α2,⋯ ,αn− 1 ≥ 0. The proof is based on a new coupling idea from game theory. As an application, we get the same regularity estimate for viscosity solutions of the PDE $…
Regularity for nonlinear stochastic games
2015
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed
Dynamics in Interaction in Bilingual Team Teaching: Examples from a Finnish Preschool Classroom
2018
The current study aims to explore team teaching as it is manifested in bilingual interactional patterns in a preschool classroom in Finland. The data was collected in a preschool classroom where a bilingual pedagogy in Finnish (majority language) and Swedish (minority language) was implemented with monolingual Finnishspeaking children. Video recordings were made while two teachers with different predefined language roles were team teaching a class of 20 children during two circle times. A two-level analytic model was developed: on the macro level activity types, participant roles (type of leadership) and language allocation (the teachers’ relative use of Finnish and Swedish) were identified…
Interaction between students and class teachers in vocational education and training: ‘Safety distance is needed’
2020
Interaction between students and teachers is fundamental and has therefore been widely studied in education. However, there have been few studies on intensive spe-cial support being provided to vocational education and training (VET) students. Firstly, the focus of this article is on students’ perceptions of interactions with their class teachers. Students (aged 17–34 years) from four Finnish vocational institutions providing intensive special support were interviewed. According to the findings, the demands students placed on their class teachers and for interactions with them were modest and their perceptions of both were favourable. Interactions seemed to be study-orientated and class tea…
