Spanish Adaptation and Validation of the Outcome Questionnaire OQ-30.2

2017

This study assessed the psychometric properties of a Spanish version of the Shortened Outcome Questionnaire (OQ-30.2, Lambert et al., 2004) validated with a sample of 546 patients in an outpatient mental health clinic and 100 non-clinical adults in Chile. Our results show that this measure has similar normative data to the original measure, with a cutoff score for the Chilean population set at 43.36, and the reliable change index at 14. This Spanish OQ-30.2 has good internal consistency (α = 0.90), has concurrent validity with the Depressive, Anxious, and Somatoform disorders measuring scale (Alvarado and Vera, 1991), and is sensitive to change during psychotherapy. Consistent with previous…

Research Summary We explore the qualitative differences in entries and exits over time. Using qualitative and quantitative data on 96 firms over 200 years, we study industry evolution from the perspective of individual decision‐making situations. Our historical and statistical analyses reveal the vital role of technology investments in determining firm outcomes, and the technological, institutional and governance dynamics that lead firms to invest or to abstain. Our main theoretical and methodological contribution concerns the importance of the multiplicity of firm‐level rationalities and decisions as fundamentals in theorizing on industry evolution. Managerial Summary What determines firm …

A Configurational Approach to Analyze Family Governance and Family Firm Outcome Preferences

2020

This chapter follows the new research current that looks for heterogeneity between family businesses and its consequences. Through a cluster analysis, the chapter presents a taxonomy of four groups with different family government profiles, depending on the scope—number of issues considered—and the level of formalization. Alike, the research describes the different relative importance that each group attaches a to financial and non-financial performance measures, as well as to the dimensions of business and family success. The chapter analyzes a sample of 147 SME family businesses that belong to the tourism industry. All of them are closely held family businesses that range between the firs…

The facility location problem with capacity transfers

2020

Abstract This paper explores the concept of capacity transfer in the context of capacitated facility location problems. This is accomplished by assuming that facilities with surplus capacity/production can cooperate with those facing shortage by transferring part of that capacity/production. Such a transfer incurs a cost that nonetheless may be compensated by savings both in the installation costs and in the distribution costs. Mixed-integer mathematical programming models are proposed for the problem. A distinction is made between the case in which the triangle inequality holds for the transfer costs and the case in which it does not. We present compact models, which are enhanced with vali…

‘Tool port’ to ‘landlord port’: a game theory approach to analyse gains from governance model transformation

2018

This study investigates potential port users’ surplus and terminal operators’ profits due to transforming port governance from the ‘tool port’ model to the ‘landlord port’ model. Although the landl...

Commentary: ethnography, critique and the state. Some thoughts on “fiscal anthropological insights into the heart of contemporary statehood”1

2018

This commentary explores the assets and liabilities of anthropology for the study of core functions of statehood (such as taxation) that increasingly become a matter of transnational negotiation an...

Non-convex power allocation games in MIMO cognitive radio networks

2013

Consideramos un escenario de reparto del espectro, basado en la detección, en una red de radio cognitiva MIMO donde el objetivo general es maximizar el rendimiento total de cada usuario de radio cognitiva optimizando conjuntamente la operación de detección y la asignación de potencia en todos los canales, bajo una restricción de interferencia para los usuarios primarios. Los problemas de optimización resultantes conducen a un juego no convexo, que presenta un nuevo desafío a la hora de analizar los equilibrios de este juego. Con el fin de hacer frente a la no convexidad del juego, utilizamos un nuevo concepto relajado de equilibrio, el equilibrio cuasi-Nash (QNE). Se demuestran las condicio…

Die Herausbildung von Zufriedenheits-urteilen bei Alternativenbetrachtung

1999

Traditional elements of competitive differentiation are declining. As industries and firms worldwide face increasing competition, slower growth rates, and price pressures, greater attention is being placed on customer satisfaction. However the research in satisfaction never consider alternatives, when customer satisfaction is formed. It has been the approach of this paper to present an extension for this circumstance. Therefor the regret theory, a diversion of the expectation utility theory, is used to explain the phenomena. According to this theory, each outcome has associated with it the evaluation of the difference between the outcome and the outcome that would have been received had a d…

Utility-based resource allocations in multi-hop wireless networks

2011

It is well known that CSMA (Carrier Sense Multiple Access) protocols exhibit very poor performance in case of multi-hop transmissions, because of inter-link interference due to imperfect carrier sensing. Since ad-hoc networks based on multihop packet deliveries are becoming more and more common in different application and networking scenarios, different medium access control extensions are currently considered for improving the channel utilization efficiency. In this paper, we propose a simple approach based on preallocating temporal slots in which different sets of nodes are allowed to contend for the channel access, which can significantly improve CSMA performance with limited signaling …

Engineering Self-adaptive Systems: From Experiences with MUSA to a General Design Process

2019

Designing and developing complex self-adaptive systems require design processes having specific features fitting and representing the complexity of these systems. Changing requirements, users’ needs and dynamic environment have to be taken in consideration, also considering that, due of the self-adaptive nature of the system, the solution is not fixed at design time but it is a run-time outcome. Traditional design approach and life cycles are not suitable to design software systems where requirements continuously change at runtime. A new design process paradigm is needed to design such systems. In this Chapter, we present a retrospective analysis based on three projects developed in the las…
