Examining the Impact of Innovation Forms on Sustainable Economic Performance: The Influence of Family Management

The aim of this research is to explore the effect that innovation, as a potential source of sustained competitive advantage and firm growth, has on the achievement of sustainable economic performance. In particular, this paper empirically examines the influence of four innovation forms (intramural R&D, extramural R&D, product innovation, and process innovation) on firms’ sustainable economic performance, considering the moderating effect of family involvement in management. To test the hypotheses, random-effects regression analyses are applied to a longitudinal sample of 598 Spanish private manufacturing firms throughout the 2006–2015 period. The results show a negative effect of intramural and extramural R&D on sustainable economic performance and a positive effect of process innovation on sustainable economic performance. Moreover, a reinforced relationship between process innovation and sustainable economic performance is also revealed when family involvement in management acts as a moderator. The findings make several contributions to research and practice

Analysis of assessment tools of Engineering degrees

This work presents an analysis of the assessment tools used by professors at the Universitat Politécnica de Catalunya to assess the generic competencies introduced in the Bachelor’s Degrees in Engineering. In order to conduct this study, a survey was designed and administered anonymously to a sample of the professors most receptive to educational innovation at their own university. All total, 80 professors responded to this survey, of whom 26% turned out to be members of the university’s own evaluation innovation group (https://www.upc.edu/rima/grups/grapa), GRAPA. This percentage represents 47% of the total GRAPA membership, meaning that nearly half of the professors most concerned about evaluation at the university chose to participate. The analysis of the variables carried out using the statistical program SPSS v19 shows that for practically 49% of those surveyed, rubrics are the tools most commonly used to assess generic competencies integrated in more specific ones. Of those surveyed, 60% use them either frequently or always. The most frequently evaluated generic competencies were teamwork (28%), problem solving (26%), effective oral and written communication (24%) and autonomous learning (13%), all of which constitute commonly recognized competencies in the engineering profession. A two-dimensional crosstabs analysis with SPSS v19 shows a significant correlation (Asymp. Sig. 0.001) between the type of tool used and the competencies assessed. However, no significant correlation was found between the type of assessment tool used and the type of subject, type of evaluation (formative or summative), frequency of feedback given to the students or the degree of student satisfaction, and thus none of these variables can be considered to have an influence on the kind of assessment tool used. In addition, the results also indicate that there are no significant differences between the instructors belonging to GRAPA and the rest of those surveyed.Preprin

Simulation of a mechanical thrombectomy device based in the use of self-expandable stents for the blood clots extraction

Recently, we have presented some studies concerning the analysis, design and optimization of one experimental device developed in the UK - GPTAD - which has been designed to remove blood clots without the need to make contact with the clot itself, thereby potentially reducing the risk of problems such as downstream embolisation. Based on the idea of a modification of the previous device, in this work, we present a model based in the use of stents like the SolitaireTM FR, which is in contact with the clot itself. In the case of such devices, the stent is self-expandable and the extraction of the blood clot is faciliatated by the stent, which must be inside the clot. Such stents are generally inserted in position by using the guidewire inserted into the catheter. This type of modeling could potentially be useful in showing how the blood clot is moved by the various different forces involved. The modelling has been undertaken by analyzing the resistances, compliances and inertances effects. We model an artery and blood clot for range of forces for the guidewire. In each case we determine the interaction between blood clot, stent and artery

Do Depositors Punish Banks For "Bad" Behavior?: Examining Market Discipline In Argentina, Chile, And Mexico

This paper examines the existence of market discipline in the banking industries of Argentina, Chile, and Mexico during the 1980s and 1990s. Using a bank panel data set, we test for the presence of market discipline by studying whether depositors punish risky banks by withdrawing their deposits. We find that across countries and across deposit insurance schemes, market discipline exists even among small, insured depositors. Standardized coefficients and variance decomposition of deposits indicate that bank fundamentals are at least as important as other factors affecting deposits. GMM estimations confirm that the results are robust to the potential endogeneity of bank fundamentals.

Corporate Environmental Disclosure Practices in Different National Contexts: The Influence of Cultural Dimensions

The influence of different national contexts, including the effects of cultural environments, on corporate environmental disclosure practices has yet to be properly addressed in the literature. The purpose of this research is, therefore, to analyse how cultural factors affect the environmental disclosure practices of companies in different countries. This research is supported by the diversity of cultures across countries. Given that a cultural framework prompts different organisational actions and strategies, the question to be answered through this research is as follows: How do cultural aspects affect corporate environmental disclosure? Cultural factors are precisely those that can explain similarities and differences between stakeholders’ actions and preferences. The sample used in this research comprises companies in 28 countries and 9 economic sectors for the period 2004 to 2015. Our main findings show that companies operating in countries with individualist, masculine and indulgent cultures are less likely to disclose environmental information. Contrary to our predictions, cultures with a longterm orientation also discourage the reporting of environmental information, while uncertainty avoidance contexts tend to promote more environmental reporting

The Identity of a Landscape: Andalusi and Castilian Orchards and Gardens in Murcia in the 13th Century

Reconstrucción del paisaje del regadío de Murcia en el siglo XIII, centuria en la que converge el legado hidráulico andalusí trasvasado al nuevo dominio castellano. La interpretación de textos árabes y castellanos compilados junto a algunos testimonios arqueológicos permite analizar la evolución de un paisaje natural milenario de agua y tierra a un paisaje humanizado por la sociedad islámica a partir del siglo IX con la fundación de Madinat Mursiya. Este desarrollado legado paisajístico de la huerta mursí, perdurable en la antroponimia y topominia, comenzaba no obstante a transformarse en poder de la sociedad cristiana en las décadas finales del siglo XIII.This article studies the reconstruction of the landscape of the irrigated land of Murcia in the 13th century, at the time when it came under the dominion of Castile. The interpretation of Arabic and Castilian texts, together with archaeological testimonies, allows us to analyse how an ancient natural landscape of water and land had been transformed by the Muslims with the foundation of Madinat Mursiya in the 9th century. This legacy of a cultivated landscape of orchards and gardens began to change, however, with the arrival of the Christians during the final decades of the 13th century. Personal names and place names, on the other hand, did not change in the same way

Characterising epithelial tissues using persistent entropy

In this paper, we apply persistent entropy, a novel topological statis- tic, for characterization of images of epithelial tissues. We have found out that persistent entropy is able to summarize topological and geomet- ric information encoded by -complexes and persistent homology. After using some statistical tests, we can guarantee the existence of signi cant di erences in the studied tissues.Ministerio de Economía y Competitividad MTM2015-67072-

Persistent entropy: a scale-invariant topological statistic for analyzing cell arrangements

In this work, we develop a method for detecting differences in the topological distribution of cells forming epithelial tissues. In particular, we extract topological information from their images using persistent homology and a summary statistic called persistent entropy. This method is scale invariant, robust to noise and sensitive to global topological features of the tissue. We have found significant differences between chick neuroepithelium and epithelium of Drosophila wing discs in both, larva and prepupal stages. Besides, we have tested our method, with good results, with images of mathematical tesselations that model biological tissues
