Learning competitive pricing strategies by multi-agent reinforcement learning

2003

Abstract In electronic marketplaces automated and dynamic pricing is becoming increasingly popular. Agents that perform this task can improve themselves by learning from past observations, possibly using reinforcement learning techniques. Co-learning of several adaptive agents against each other may lead to unforeseen results and increasingly dynamic behavior of the market. In this article we shed some light on price developments arising from a simple price adaptation strategy. Furthermore, we examine several adaptive pricing strategies and their learning behavior in a co-learning scenario with different levels of competition. Q-learning manages to learn best-reply strategies well, but is e…

Adaptation interventions and their effect on vulnerability in developing countries: Help, hindrance or irrelevance?

2021

This paper critically reviews the outcomes of internationally-funded interventions aimed at climate change adaptation and vulnerability reduction. It highlights how some interventions inadvertently reinforce, redistribute or create new sources of vulnerability. Four mechanisms drive these maladaptive outcomes: (i) shallow understanding of the vulnerability context; (ii) inequitable stakeholder participation in both design and implementation; (iii) a retrofitting of adaptation into existing development agendas; and (iv) a lack of critical engagement with how ‘adaptation success’ is defined. Emerging literature shows potential avenues for overcoming the current failure of adaptation intervent…

Différenciation pédagogique et inclusion scolaire : interroger les pratiques d'adaptation des enseignements

2018

National audience; Cette intervention vise à susciter des questionnements sur les pratiques des enseignants dans une démarche de culture partagée, elle sera orientée vers la prévention des ruptures des cursus scolaires / la sécurisation des parcours scolaires et organisée autour de trois axes suivants : 1 - La différenciation en classe : pourquoi et comment la mettre en oeuvre ? ; 2 - La différenciation au service d'une exigence : en quoi est-ce une ressource pour le parcours de l'élève ? ; 3 - Le double lien entre la différenciation et l'inclusion scolaire : la différenciation comme outil de l'inclusion et l'inclusion comme outil de la différenciation

2-D difference gel electrophoresis approach to assess protein expression profiles in Bathymodiolus azoricus from Mid-Atlantic Ridge hydrothermal vent…

2011

Hydrothermal vent mussels Bathymodiolus azoricus are naturally exposed to toxic chemical species originated directly from vent chimneys. The amount of toxic elements varies significantly among vent sites along the Mid-Atlantic Ridge and B. azoricus must be able to adapt to changes in hydrothermal fluid composition, temperature and pressure. The aim of this work was to study changes in the proteome in the "gill-bacteria complex" of mussels B. azoricus from three hydrothermal vent sites with distinct environmental characteristics using 2-D Fluorescence Difference Gel Electrophoresis (2-D DIGE). Results showed that 31 proteins had different expression profiles among vent sites and both cluster…

Vindicating Pablo Avecilla’s Spanish ‘Imitation’ of Hamlet (1856)

2012

This essay examines Pablo Avecilla’s Hamlet, an ‘imitation’ of Shakespeare’s tragedy of the prince of Denmark published in 1856, both in its own terms and in the historical context of its publication. This Shakespearean adaptation has been negatively judged as preposterous and unworthy of comment, but it deserves to be approached as what it claimed to be, a free handling of the Shakespearean model, and as responding to its own cultural moment. Avecilla turns the Shakespearean sacrificial prince into a righteous sovereign that has kept the love of a lower-ranked lady and, by pursuing revenge, has successfully overthrown a dishonourable and corrupt ruler. This re-focusing of the Shakespearean…

The Italian adaptation and validation of the Adult Sibling Relationship Questionnaire (ASRQ) in Italian emerging adults

2013

The aims of the present study were to provide a contribution to the validation of the Adult Sibling Relationship Questionnaire (ASRQ) (Stocker, Lanthier, & Furman, 1997) with a population of Italian emerging adults. The ASRQ measures individuals’ current perceptions of their own behaviour and feelings toward their sibling, as well as their perceptions of their sibling’s behaviour and feelings toward him or her by assessing fourteen fundamental dimensions (Intimacy; Affection; Emotional Support; Instrumental Support; Knowledge; Similarity; Admiration; Acceptance; Dominance; Competition; Antagonism; Quarrelling; Maternal Rivalry; and Paternal Rivalry), combined in order to form three macro-di…

Striving to maintain a dignified life for the patient in transition: Next of kin’s experiences during the transition process of an older person in tr…

2015

Next of kin represent significant resources in the care for older patients. The aim of this study was to describe and illuminate the meaning of the next of kin’s experiences during the transition of an older person with continuing care needs from hospital to home. The study has a phenomenological hermeneutic design. Individual, narrative interviews were conducted, and the data analysis was conducted in accordance with Lindseth and Norberg’s phenomenological hermeneutic method. Two themes and four subthemes were identified and formulated. The first theme: “Balancing vulnerability and strength,” encompassed the subthemes “enduring emotional stress” and “striving to maintain security and conti…

Development of need for recovery from work over one year: A person-centered approach

2011

This longitudinal questionnaire study conducted among 274 Finnish employees (57% women, average age 45.9 years) in a variety of jobs aimed at identifying groups of employees who share similar mean levels and changes in need for recovery and finding out whether factors regarded as antecedents of need for recovery distinguish between the different groups of need for recovery across one year. Using mixture modeling eight groups of need for recovery were identified. The individuals identified as closely resembling each other with respect to need for recovery and its change across one year were considered to belong to the same need for recovery group. Five of these groups indicated stable (low, …

Una revisión a la planificación de los recursos: sobre los enfoques de evaluación y los modelos de adaptación al uso turístico

2018

Mucho se ha hablado de la planificación del turismo. Solo cabe echar una mirada a la literatura académica para encontrar decenas de propuestas metodológicas que, desde inicios de los años 50 del siglo pasado, vienen exponiéndose. A pesar de esta vorágine creativa, todas ellas acaban, finalmente, enmarcándose en uno de los cinco enfoques identificados por Hall (2008). Sin embargo, al realizar ese mismo ejercicio para el caso de los recursos, considerados la base sobre la que asentar cualquier proceso de desarrollo turístico, los resultados sobre cómo planificarlos difieren considerablemente. Esta investigación, de carácter teórico, realiza una revisión bibliográfica de los trabajos académico…
