The dynamic interdependence in the demand of primary and emergency secondary care: A hidden Markov approach
2021
This paper develops an extension of the class of finite mixture models for longitudinal count data to the bivariate case by using a trivariate reduction technique and a hidden Markov chain approach. The model allows for disentangling unobservable time-varying heterogeneity from the dynamic effect of utilisation of primary and secondary care and measuring their potential substitution effect. Three points of supports adequately describe the distribution of the latent states suggesting the existence of three profiles of low, medium and high users who shows persistency in their behaviour, but not permanence as some switch to their neighbour's profile.
Networked relationships in the e-MID Interbank market: A trading model with memory
2014
Interbank markets are fundamental for bank liquidity management. In this paper, we introduce a model of interbank trading with memory. Our model reproduces features of preferential trading patterns in the e-MID market recently empirically observed through the method of statistically validated networks. The memory mechanism is used to introduce a proxy of trust in the model. The key idea is that a lender, having lent many times to a borrower in the past, is more likely to lend to that borrower again in the future than to other borrowers, with which the lender has never (or has in- frequently) interacted. The core of the model depends on only one parameter representing the initial attractiven…
Institutional distance and international networking
2017
We focus on how small- and medium-sized enterprises (SMEs) adapt to differences in institutional logics (values, beliefs, and rules) in their networking when they enter an institutionally distant market. We address gaps in the literature, relating to the role of institutional logics in SME internationalization, and how institutional distance affects the formation of network ties. We show how the social interaction involved in internationalization is embedded in the institutional logics followed by partnering actors. Specifically, we demonstrate how institutional distance may constrain the networking activities of SMEs and identify practices that may support successful internationalization. …
Radical innovations: Between established knowledge and future research opportunities
2021
Abstract The fast growing body of radical innovation research is fragmented and difficult to overlook. We provide an overview of the most cited journals, authors, and publications and conduct a bibliographic coupling to structure the literature landscape. We identified the following research clusters: management of radical innovations, organizational learning and knowledge, financial aspects of radical innovation, radical innovation adoption and diffusion, radical industry innovations as challenges for incumbents, and radical innovation in specific industries. Based on an in-depth content analysis of these clusters, we identify the following future research opportunities: A systematic compi…
Customer functional value creation through a sustainable entrepreneurial orientation approach
2019
This paper advances a theoretical model to empirically test firms’ behaviour regarding sustainable entrepreneurship, enhancing what researchers have recently proposed at a solely conceptual level; this entails sustainable entrepreneurship being understood as a discipline that reliably allows organizations to successfully respond to sustainable development and market requirements. The authors suggest an integrated approach of dynamic-capabilities, S-D logic and product-service system views, which highlights the managerial predisposition to adopt a strategic position that fosters value in use (instead of regular property value), according to the current school of thoughts engaged with innovat…
Blind justice: An experimental analysis of random punishment in team production
2010
We study the effect of blind punishment in a team production experiment, in which subjects choose non-observable effort levels. In this setting, a random exclusion mechanism is introduced, linked to the normalized group performance (R, from 0 to 1). Every round, each subject is non-excluded from the collective profit with probability R (and with probability 1 ! R gets no benefit from the group account). Punishment does not depend on the individual behavior, but the probability of being punished reflects collective performance. As the exclusion probability is computed at the group level, no individual information is needed to implement exclusion. However, the probabilistic punishment risks t…
Empirical definition of social types in the analysis of inequality of opportunity: a latent classes approach
2014
The empirical analysis of inequality of opportunity centres on disparities between social types, defined by the exposure to circumstances beyond individual control. Despite this, its main theoretical foundation—the Roemer model—does not indicate how to carry out, in practice, the required partition of the population into such types. This paper operationalises this definition of social types using a latent classes approach. Our specification is embedded in a probabilistic extension of the canonical Roemer model, which assumes that the relevant population consists of a finite number of latent types, from which each individual can be treated as a random draw. This makes possible the use of the…
Institutional Logics in Police Performance Indicator Development : A Comparative Case Study of Spain and Finland
2015
Police performance is not easily measurable and the organization and circumstances of police work vary among European countries. Further, police work is surrounded by multiple pressures to make it both economical and effective. Consequently, there are multiple institutional logics in decision-making which may affect the selection and the use of police key performance indicators (KPIs). The KPI selection and use processes reflect the institutional logics, though KPI use may also sometimes influence the institutional logics of police work. In this study, we analyze the KPIs and institutional logics in police work in Finland and Spain. A comparative case research approach is used in order to h…
Remote diagnosis and control of wheelchair electrical drive systems
2005
A new Diagnostic and Protective System (DPS) suitable for wheelchair electrical drive applications has been prepared. Such a system is able to perform both monitoring and long-distance transmission of key signals that are used as pre-fault and fault indicators. The system, moreover, may detect several anomalous working conditions by means of reliable diagnosis procedures and carries out actions to protect the electrical drive and to drive the disabled people in safe conditions. In particular the design, the realization and the performance analysis of the new dedicated diagnostic system, which exploits a programmable logic controller (PLC) as DRS hardware, are described and discussed. The ef…
The extended CC2 model ECC2
2013
We present a size-extensive extension to the CC2 model that avoids the complications with quasi-degeneracies that are present in the CC2 model and related perturbation theory-based approaches. The formulation also provides a consistent model for treating different parts of a molecular system at different levels of electron correlation. Such a subsystem approach leads to large reductions in the computational requirements without compromising the accuracy. In this initial study, we focus on static molecular properties. © 2013 Copyright Taylor and Francis Group, LLC.
