Family business internationalisation and networks: emerging pathways
2017
Purpose The aim of this study is twofold: to provide a meta-synthesis of the current state of knowledge in family business (FB) internationalisation research, adopting a network perspective, and to highlight emerging themes that may set the stage for future work on FB internationalisation, for the benefit of researchers adopting a network perspective. Design/methodology/approach To address the twofold purpose of the study, the current paper provides a state-of-the-art review of 25 peer-reviewed journal articles published from 1993 to 2014. This study also presents a meta-synthesis of the theoretical approaches, key findings and concepts that were pinpointed in the review, and proposes emer…
Percepción de los estudiantes universitarios ante una actividad audiovisual con dispositives móviles: un estudio de caso.
2020
El presente estudio radica en el interés que aportan las manifestaciones de los estudiantes universitarios de Magisterio, futuros maestros, desde una vertiente cualitativa y, en menor medida, cuantitativa, sobre el uso de los dispositivos portables, en concreto los teléfonos móviles con apoyo de la red social Facebook, en el proceso de enseñanza y aprendizaje. Se trata de una experiencia educativa centrada en la creación de audiovisuales mediante dispositivos móviles. Los resultados avalan, por un lado, la importancia que los discentes atribuyen al recurso y la motivación que les genera el uso de estas innovadoras metodologías con TIC. Otorgan valor a la necesidad de actualizarse tecnológic…
Towards Resilient Organisations and Societies? Reflections on the Multifaceted Nature of Resilience
2021
AbstractAs the chapters in this volume have shown, resilience is a multifaceted and malleable concept that can be fruitfully applied to a wide range of phenomena at all levels of society. At the same time, there is a distinct danger of concept stretching. In this concluding chapter, we look at both the extensiveness of the concept, reviewing the range of complementary concepts that have been engaged by the authors, and how it can be delimited to maintain conceptual distinctiveness and explanatory value. What is more, we provide some recommendations on how scholars working across disciplinary boundaries may go about unpacking resilience in and for organizations and societies.
Business continuity of business models : Evaluating the resilience of business models for contingencies
2019
Company business models are vulnerable to various contingencies in the business environment that may unexpectedly render their business logic ineffective. In particular, technological advancements, such as the Internet of things, big data, sharing economy and crowdsourcing, have enabled new forms of business models that can effectively and abruptly make traditional business models obsolete. By disrupting or even diminishing companies’ revenue streams, environmental contingencies may present a significant threat to business continuity (BC). Evaluating the resilience of business models against these contingencies should therefore be a core area of BC. However, existing BC approaches tend to f…
AN EMPIRICAL VIEW ON VALUE THEORY AND VALUE-BASED MANAGEMENT
2016
The main economic purpose of a business organization is to create value for its owner. The value concept is a complex notion that has developed alongside human history and reflects the concerns of human society through time. As a result of the value theory, the management of value has also emerged as an essential and accompanying activity. Value-based management emerged as a management philosophy rather than a management method. It consists of a change in mindset from managing resources or output quantities to value creation. The challenge is to identify or create the value flows and act upon these within the specific business organization to have proper value management. Value creation and…
L’Analytic Network Process nei processi di trasformazione urbana. Un caso studio a Palermo come occasione per alcune considerazioni teorico-applicati…
2015
Le valutazioni multidimensionali costituiscono un valido strumento a supporto del processo decisionale in risposta a quesiti di tipo diverso (problem solving, ranking, sorting, designing). In particolare, quando i quesiti sono riferiti alle trasformazioni urbane e territoriali, le valutazioni multidimensionali: sono in grado di rappresentare la complessità degli elementi coinvolti a diversi livelli (ad es. ambientale, economico, finanziario, culturale e sociale); facilitano l’esplicitazione dei nodi di conflittualità o di convergenza della pluralità di soggetti portatori di differenti sistemi di valori, di obiettivi e di conoscenze tecniche; rendono trasparenti e ripercorribili tutte le fas…
Use of neurofuzzy networks to improve wastewater flow-rate forecasting
2009
A neurofuzzy wastewater flow-rate forecasting model (NFWFFM) has been developed and tested with actual data measured at the input of two wastewater treatment facilities which treat the wastewater corresponding to 150,000 and 1,250,000p.e., respectively. Good agreements between forecasted and actual flow-rates were obtained. The artificial intelligence algorithm uses only two input variables (day of the week and average daily flow-rate of day before) and one output variable (predicted average daily flow-rate). Using three months data for training the network, a long-term forecast (one month) is made with average errors below 10%. Results were compared with those obtained by applying the Cens…
Tracking control of network distributed systems in presence of variable time delay and loss of information
2006
This paper deals with the control of network distributed systems which has been at the centre of interest in a wide area of research in the last few year. The control of such systems is very difficult because the communication networks inevitably introduce variable time delays and possible lost of samples. In particular, it is proposed an extension of the approach, derived in the contest of the optimal stochastic regulator problem [1], [2], to the remote tracking problem considering a distributed control system in which the signals from the transducers to the controller and from the controller to the actuator are transmitted through a communication network with variable delays and possible …
Soft variable structure controller design for singular systems
2015
Abstract A novel soft variable structure control (SVSC) scheme is addressed for a class of singular systems under I-controllable in this paper. The structural features of SVSC with differential equations are investigated. The stability of singular systems based on SVSC scheme is guaranteed by an equivalent characterization theory, and then a soft variable structure controller is designed. The concrete algorithm of SVSC with differential equations is proposed. The developed SVSC law for singular systems is carried out for the purpose of achieving rapid regulative rate, and shortening arrival time. Moreover, system chattering can be attenuated in the process of approaching to the equilibrium …
Reproduction of kinematics of cars involved in crash events using nonlinear autoregressive models
2012
Vehicle crashworthiness can be assessed by the variety of methods - the most common and direct one is a vehicle crash test. Visual inspection and obtained measurements, such as car acceleration, are used to examine impact severity of an occupant and overall car safety. However, those experiments are complex, time-consuming, and expensive. We propose a method to reproduce car kinematics during a collision using a feedforward neural network to estimate the system by use of nonlinear autoregressive (NAR) models. Specifically, feasibility of applying neural networks with an NAR model to the analysis of experimental data is explored by application to measurements of a vehicle crash test. This mo…
