Three decades of subsidiary exits: Parent firm financial performance and moderators
2020
Abstract This study aimed to find important constructs and relationships among models of subsidiary divestment during the period from 1989 to 2018 using correlation matrices of 80 studies, the selection of which was based on six criteria. It revealed eight important constructs, namely firm innovativeness, environmental factors in the target country, type of experience, organizational characteristics, investment strategy, parent firm financial performance, subsidiary divestment, and the moderating effects of advertising intensity and product diversification. Furthermore, it shed light on seven relationships that should be considered in future attempts to assess parent performance related to …
The effect of high performance work systems on small and medium size enterprises
2015
Abstract This study analyzes the processes that explain high performance work system (HPWS) effect on company performance in small and medium size enterprises (SMEs). This study tests this relationship in SMEs by selecting three high performance work practices (HPWP) and an outcome variable based on the return on investment. A regression model with a sample of 78 companies tests the hypothesis. Results confirm the positive effect of HPWP on the performance of SMEs.
Performance analysis of research spin-offs in the Spanish biotechnology industry
2012
Abstract This study examines whether the performance of biotechnology research spin-offs in Spain differs from non spin-off firms, using empirically-based fieldwork over a 5-year period and standard dichotomous regression analysis on 7-year data. Biotechnology research spin-offs in Spain are not necessarily located in core regions, are smaller in size and tend to grow faster in terms of turnover. Corporate groups seldom control them but venture capitalists have a greater tendency to acquire shareholdings in them. Compared to non spin-off firms, research spin-off firms face more serious and more numerous challenges and disadvantages. Only two advantages are apparent: their capacity to attrac…
Predictors of tourist engagement: Travel motives and tourism destination profiles
2020
Abstract The aim of this study is to investigate the influence of travel motives and regional tourism destinations on positive/negative engagement with a destination management organisation (DMO). According to previous literature, travel motives were classified as push and pull motives, and regional tourism destinations were classified by tourist demand behaviour. To achieve the objective, the totality of posts about regional tourism destinations published on the Brand Spain's Official Facebook Fanpage during a year were analysed (418), along with audience reactions (127,750), comments (3219) and shares to such posts. A content analysis was performed, with a regression analysis (optimal sca…
The influence of geographical concentration and structural characteristics on the survival chance of textile firms
2013
[EN] Purpose The purpose of this paper is to evaluate the contribution of location (geographical concentration) and firm structure (age and subsector) to the risk of business failure. Design/methodology/approach The Markov s regression analysis was made for a sample of over 11,700 Spanish textile-clothing firms. Findings The results obtained from the analysis suggest that the risk of business failure is increased by some risk factors relative to the structural characteristics of the firms (younger firms and specialization in low-tech activities), and under determined locational circumstances. Research limitations/implications Our conclusions have been obtained starting from a sample of manu…
Effects of endodontic treatment on apparent Young’s modulus of human teeth: in vitro study using speckle interferometry
2012
The introduction of new techniques for endodontic procedures requires the analysis of the biomechanical behavior of dental structures. Digital speckle shearing pattern interferometry (DSSPI) is a nondestructive optical measuring technique that allows one to directly quantify deformations in teeth that are subjected to stress. DSSPI technique was applied to measure small deformations caused by flexion in different types of teeth. The test was carried out both before and after endodontic treatment with the ProTaper method in order to evaluate the variation of dental elasticity, taking into the account the type of tooth and the endodontic treatment. The results obtained show that dental elasti…
Smart load prediction analysis for distributed power network of Holiday Cabins in Norwegian rural area
2020
Abstract The Norwegian rural distributed power network is mainly designed for Holiday Cabins with limited electrical loading capacity. Load prediction analysis, within such type of network, is necessary for effective operation and to manage the increasing demand of new appliances (e. g. electric vehicles and heat pumps). In this paper, load prediction of a distributed power network (i.e. a typical Norwegian rural area power network of 125 cottages with 478 kW peak demand) is carried out using regression analysis techniques for establishing autocorrelations and correlations among weather parameters and occurrence time in the period of 2014–2018. In this study, the regression analysis for loa…
Parametric and nonparametric methods to generate time-varying surrogate data.
2009
We present both nonparametric and parametric approaches to generating time-varying surrogate data. Nonparametric and parametric approaches are based on the use of the short-time Fourier transform and a time-varying autoregressive model, respectively. Time-varying surrogate data (TVSD) can be used to determine the statistical significance of the linear and nonlinear coherence function estimates. Two advantages of the TVSD are that it keeps one from having to make an arbitrary decision about the significance of the coherence value, and it properly takes into account statistical significance levels, which may change with time. Our simulation examples and experimental results on blood pressure …
Sensitivity of extreme rainfall to temperature in semi-arid Mediterranean regions
2019
Abstract Warmer air has the potential to hold more water vapour and, therefore, to provide more water to rainfall events. Studying the relationship between rainfall and temperature represents an emerging issue in hydrology and meteorology, since it can be considered fundamental for evaluating the effects of global warming on future precipitation. Various approaches have been tested across different parts of the world, in many cases observing an intensification of extreme precipitation at higher temperatures consistent with the well-known thermodynamic Clausius-Clapeyron relation (CC-scaling rate of 6–7%°C−1). However, at different locations for hourly time-scales, the temperature-extreme ra…
A time series study on the effects of heat on mortality and evaluation of heterogeneity into European and Eastern-Southern Mediterranean cities: resu…
2013
Background: The Mediterranean region is particularly vulnerable to the effect of summer temperature. Within the CIRCE project this time-series study aims to quantify for the first time the effect of summer temperature in Eastern-Southern Mediterranean cities and compared it with European cities around the Mediterranean basin, evaluating city characteristics that explain between-city heterogeneity. Methods: The city-specific effect of maximum apparent temperature (Tappmax) was assessed by Generalized Estimation Equations, assuming a linear threshold model. Then, city-specific estimates were included in a random effect meta-regression analysis to investigate the effect modification by several…
