Factors influencing automobile firms eco-innovation orientation
2014
[EN] An eco-innovation is any innovation that reduces environmental damage. Even though eco-innovating is a key trend in industry today, relatively little research has been conducted on its implications for the automobile industry. In this article, the attitude toward the environment while innovating is analyzed using the SEM (Structural Equation Model) technique, applied to a data set of 223 Spanish automotive companies. Results of a statistical analysis with this data set show that companies which focus on processes and products when innovating tend to be more environmentally oriented and tend to highlight the importance of information sources more than those which do not have a focus on …
Relationship between employee involvement and lean manufacturing and its effect on performance in a rigid continuous process industry
2015
Relationship between employee involvement and lean manufacturing and its effect on performance in a rigid continuous process industry DOI: 10.1080/00207543.2014.975852 Juan A. Marin-Garciaa* & Tomas Bonaviab Received: 1 Aug 2013 Accepted: 30 Sep 2014 Published online: 04 Nov 2014 This research aims to empirically test the effect of employee involvement on lean manufacturing (LM), and the effect of LM on production outcomes. Employee involvement is operationalised through four related variables: empowerment, training, contingent remuneration and communication. The effects are tested by recording management perceptions in a different industrial sector from those usually studied in previous re…
Stop there’s water on the road! Identifying key beliefs guiding people’s willingness to drive through flooded waterways
2016
Floods are among the most widespread of natural disasters and exposure to floodwaters increases drowning risk. A leading cause of flood related drowning deaths is driving through flooded waterways. Drawing on the Theory of Planned Behaviour, a two-phased research program was conducted. Phase 1 (N = 25; Mage = 32.38, SD = 11.46) identified common beliefs about driving through a flooded waterway. Phase 2 (N = 174; Mage = 27.43, SD = 10.76) adopted a cross-sectional design to examine the belief predictors of drivers' willingness to drive through a flooded waterway. Given differences in consequences due to the depth of water, scenarios of low (road covered in 20 cm of water) and high (road cove…
New venture creation : a systematic review of associated literature
2020
RESUMEN La creación de nuevas empresas es una faceta integral del emprendimiento y, como consecuencia, ha sido objeto de una mayor atención de investigación dentro de la literatura existente. Aunque se ha ganado impulso en busca de explicar este fenómeno amplio y diverso, existe un gran potencial para ampliar nuestra comprensión. El progreso en la expansión del conocimiento será más efectivo si somos capaces de construir de manera constructiva a partir de focos comunes explícitamente reconocidos que puedan servir como base para una contribución cooperativa. El presente artículo busca proporcionar una visión general temática actualizada a través de medios sistemáticos de los principales inte…
Uso de indicadores bibliométricos para el análisis de temas emergentes y su evolución: spin-offs como caso de estudio
2018
[ES] Las spin-offs constituyen una de las áreas de investigación más atractivas, ya que están asociadas con fenómenos como el emprendimiento, la innovación y la transferencia del conocimiento. El presente estudio muestra que la selección y el uso de indicadores bibliométricos permite identificar y caracterizar el desarrollo y la difusión de temas de investigación emergentes como el analizado. Los principales aspectos observados en relación con el desarrollo de la investigación sobre las spin-offs son que se produce un auge en el número de publicaciones después de un largo período de latencia y la marcada naturaleza multidisciplinar del área. El presente enfoque ha analizado la evolución de …
Volcanogenic fluorine in rainwater around active degassing volcanoes: Mt. Etna and Stromboli Island, Italy
2002
Many studies have assessed the strong influence of volcanic activity on the surrounding environment. This is particularly true for strong gas emitters such as Mt. Etna and Stromboli volcanoes. Among volcanic gases, fluorine compounds are potentially very harmful. Fluorine cycling through rainwater in the above volcanic areas was studied analysing more than 400 monthly bulk samples. Data indicate that only approximately 1% of fluorine emission through the plume is deposited on the two volcanic areas by meteoric precipitations. Although measured bulk rainwater fluorine fluxes are comparable to and sometimes higher than in heavily polluted areas, their influence on the surrounding vegetation i…
Vides apstākļu ietekme uz mikro- un makroelementu saturu pārtikas produktos Latvijā
2014
Bez vitāli svarīgo mikro- un makroelementu ieneses pārtikā no vides (augsnes, ūdens un gaisa) ir iespējams arī barības ķēdes, t. sk., pārtikas piesārņojums ar toksiskiem vai potenciāli toksiskiem elementiem, piemēram, As, Cd, Hg, Pb. Promocijas darba mērķa ietvaros tika veikta Latvijā iegūtu pārtikas produktu paraugu mikro- un makroelementu sastāva kvantitatīvā analīze, lai noskaidrotu vides apstākļu ietekmi uz elementu koncentrāciju un ieneses ceļiem pārtikā. Papildus, lai vērtētu elementu biopieejamību barības ķēdē, tika veikta eksperimentāla pārtikas kultūraugu audzēšana mākslīgi piesārņotā augsnē. Iegūtie dati liecina par vairāku dabiskas un antropogēnas izcelsmes vides apstākļu, piemēr…
The impact of climate change on the distribution of rural income in Ethiopia
2018
Recent evidence suggests that global climate change is likely to increase the incidence of environmental disasters, as well as the frequency of extreme weather events. As a result, it is generally recognized that climate and weather variability has negative impacts on households’ welfare relying mainly on agriculture. In Ethiopia, 95% of the population depends on rain-fed agriculture and consequently the economic impact of climate change is crucial for small-scale farmers’ food security and welfare. The objective of this study is to provide a comprehensive analysis of the impact of climate change on rural households’ welfare in Ethiopia by using a Quantile Regression (QR) analysis. The main…
Epigenomic k-mer dictionaries: shedding light on how sequence composition influences in vivo nucleosome positioning
2014
Abstract Motivation: Information-theoretic and compositional analysis of biological sequences, in terms of k-mer dictionaries, has a well established role in genomic and proteomic studies. Much less so in epigenomics, although the role of k-mers in chromatin organization and nucleosome positioning is particularly relevant. Fundamental questions concerning the informational content and compositional structure of nucleosome favouring and disfavoring sequences with respect to their basic building blocks still remain open. Results: We present the first analysis on the role of k-mers in the composition of nucleosome enriched and depleted genomic regions (NER and NDR for short) that is: (i) exhau…
Assessment of computational methods for the analysis of single-cell ATAC-seq data
2019
Abstract Background Recent innovations in single-cell Assay for Transposase Accessible Chromatin using sequencing (scATAC-seq) enable profiling of the epigenetic landscape of thousands of individual cells. scATAC-seq data analysis presents unique methodological challenges. scATAC-seq experiments sample DNA, which, due to low copy numbers (diploid in humans), lead to inherent data sparsity (1–10% of peaks detected per cell) compared to transcriptomic (scRNA-seq) data (10–45% of expressed genes detected per cell). Such challenges in data generation emphasize the need for informative features to assess cell heterogeneity at the chromatin level. Results We present a benchmarking framework that …
