Analysing participatory video through the capability approach. A case study in Quart de Poblet (Valencia, Spain)

2017

The aim of this paper is to analyse participatory video as a participatory action research method through the lenses of the capability approach. In order to do this, we used a participatory video experience that took place in the municipality of Quart de Poblet (Valencia, Spain) from February to March 2014. The participants were 11 young people between 16 and 24 years of age, severely affected by the economic crisis that has hit Spain in recent years. To develop our analysis, we introduced the participatory video as a technique and a process within the participatory action research methods. Then, we analysed the participatory process to verify the extent to which it had contributed to expan…

Long-Term Reward Patterns Contribute to Personal Goals at Work Among Finnish Managers

2016

The research addresses the impact of long-term reward patterns on contents of personal work goals among young Finnish managers ( N = 747). Reward patterns were formed on the basis of perceived and objective career rewards (i.e., career stability and promotions) across four measurements (years 2006–2012). Goals were measured in 2012 and classified into categories of competence, progression, well-being, job change, job security, organization, and financial goals. The factor mixture analysis identified a three-class solution as the best model of reward patterns: high rewards (77%), increasing rewards (17%), and reducing rewards (7%). Participants with reducing rewards reported more progressio…

Measuring and reporting confiscated firms' (social) business value

2019

This study highlights the peculiar aspects of the business valuation process involving firms confiscated from the Mafia organisation, by pointing out some criteria to guide the selection of the appropriate valuation method. We identify some preliminary operational proposals for drawing up an effective valuation report taking social and ethical factors into account. Based on an empirical analysis carried out on a sample of Italian firm valuation reports publicly available, we find that the main business valuation choices are not explained in an in-depth manner and that there are many differences between the valuation reports and the prescriptive content proposed. Theoretical implications may…

Asymmetric modeling of organizational innovation

2015

[EN] This study revisits the theory, data, and analysis in Hervas-Oliver and Sempere-Ripoll (2014) and applies fuzzyset qualitative comparative analysis (fs/QCA) to organizational innovation effects and the influence on them of technological innovations. The influence of technological innovations (product and process) on organizational innovation and its effects is an inconclusive debate. Using fuzzy set comparative qualitative analysis (fs/QCA) on Hervas-Oliver and Sempere-Ripoll’s (2014) 9,369 organizational innovators, the present study offers more complex and nuanced antecedent conditions relating to organizational innovation beyond Hervas-Oliver and Sempere-Ripoll (2014) analysis based…

A Clinical Comparison between the Gamma® and the Claufitt® Nails in Unstable Proximal Femoral Fractures

2007

Purpose To assess the differences that exist between two intramedullary osteosynthesis systems for the treatment of unstable proximal femoral fractures in an attempt to find out whether the use of an antirotation screw improves the final result. Materials and methods A retrospective study was carried out to analyze the plcement and clinical evolution of both intramedullary nailing systems (Gamma ® y Claufitt ® ). The patients’ medium-term functional status was evaluated and benchmarked against the characteristics of the population served by our University Hospital. A final database was obtained made up of 43 cases of Claufitt ® that met the criteria of our study. A functional assessment sys…

Numerische Behandlung von Verzweigungsproblemen bei gew�hnlichen Differentialgleichungen

1979

We present a new method for the numerical solution of bifurcation problems for ordinary differential equations. It is based on a modification of the classical Ljapunov-Schmidt-theory. We transform the problem of determining the nontrivial branch bifurcating from the trivial solution into the problem of solving regular nonlinear boundary value problems, which can be treated numerically by standard methods (multiple shooting, difference methods).

Direct measurement of the melting temperature of supported DNA by electrochemical method

2003

The development of biosensors based on DNA hybridization requires a more precise knowledge of the thermodynamics of the hybridization at a solid interface. In particular, the selectivity of hybridization can be affected by a lot of parameters such as the single-strand (ss)DNA density, the pH, the ionic strength or the temperature. The melting temperature, T(m), is in part a function of the ionic strength and of the temperature and therefore provides a useful variable in the control of the selectivity and sensitivity of a DNA chip. The electrochemical technique has been used to determine the T(m) values when the probe is tethered by a DNA self-assembled monolayer (SAM). We have built a speci…

The Determination of Carbohydrates by High-Performance Anion-Exchange Chromatography Coupled with Pulsed Amperometric Detection (HPAEC-PAD)

2021

Chromatography techniques are widely used to separate, identify, and quantify molecules depending on their physicochemical properties. Standard methods range from simple size exclusion to separation based on affinity or ion exchange. Here, we present a method for the direct analysis of carbohydrates in Magnaporthe oryzae using high-performance anion-exchange chromatography (HPAEC) coupled with pulsed amperometric detection (PAD). The combination of HPAEC with PAD provides the highest selectivity and sensitivity with minimal sample preparation and cleanup time. Utilizing our HPAEC-PAD approach, we obtain reliable and highly reproducible determination of carbohydrates produced as osmotic stre…

Measurement of the first ionization potential of astatine by laser ionization spectroscopy

2013

The radioactive element astatine exists only in trace amounts in nature. Its properties can therefore only be explored by study of the minute quantities of artificially produced isotopes or by performing theoretical calculations. One of the most important properties influencing the chemical behaviour is the energy required to remove one electron from the valence shell, referred to as the ionization potential. Here we use laser spectroscopy to probe the optical spectrum of astatine near the ionization threshold. The observed series of Rydberg states enabled the first determination of the ionization potential of the astatine atom, 9.31751(8) eV. New ab initio calculations are performed to sup…

2014

This paper is concerned with the problem of general output feedback stabilization for fractional order linear time-invariant (FO-LTI) systems with the fractional commensurate order0<α<2. The objective is to design suitable output feedback controllers that guarantee the stability of the resulting closed-loop systems. Based on the slack variable method and our previous stability criteria, some new results in the form of linear matrix inequality (LMI) are developed to the static and dynamic output feedback controllers synthesis for the FO-LTI system with0<α<1. Furthermore, the results are extended to stabilize the FO-LTI systems with1≤α<2. Finally, robust output feedback control…
