Diffusion of Software Technology Innovations in the Global Context

2002

This study examines how software businesses are acquiring new software technology innovations (STIs) in rapidly changing globalized business environment characterized by rapidly shortening software technology life cycles, changing customer demands, and intense competition. It was executed through both theoretical and empirical investigations and analyses. It describes one case company as an example of the diffusion of STI and develops a framework for the diffusion of software technology innovation. The research findings are useful for both further research and industrial settings. peerReviewed

Nomenclature for Hydrogeological Instability Risks

2022

The nomenclature for hydrogeological instability risks includes four main risks, which are distinguished according to the risk causes : 1) hydrogeological risk, that is slowly caused by natural factors (e.g. collapse landslides in a calcareous cliff in uninhabited areas and erosion along a marly-calcareous slope) in environments where human activities are minimal, i.e. woods, forests and mountain pastures; 2) hydraulic-pedological farming risk, that implies the occurrence of landslides in every winter and is caused by incorrect crop selection, not suitable for the soil and climate parameters (e.g. on a hilly slope with a clay vertisol type with a landslide having different fronts, when the …

Compost Amendment Impact on Soil Physical Quality Estimated from Hysteretic Water Retention Curve

2022

Capacity-based indicators of soil physical quality (SPQ) and pore distribution parameters were proposed to assess the effects of compost amendment but their determination was limited to desorption water retention experiments. This study also considered the pore size distribution obtained from adsorption experiments to establish the effectiveness of compost amendment in modifying the physical and hydrological attributes of a sandy loam soil. Repacked soil samples with different compost to soil ratios, r, were subjected to a wetting–drying cycle, and the water retention data were fit to the van Genuchten model to obtain the pore volume distribution functions. The soil bulk density was m…

When feeling and action come together in educational practice. Relations between development education and service learning for a global citizenship

2016

Las problemáticas basadas en el desarrollo constituyen un tema recurrente eneducación. Tras resaltar la relevancia de la Educación para el Desarrollo (EpD) comoelemento fundamental en la construcción de una ciudadanía global, el objetivo de esteartículo consiste en relacionarla con una cultura educativa, el Aprendizaje Servicio(ApS). Éste pretende ser, así, un análisis teórico exploratorio e interpretativo sobre laspotencialidades que puede aportar el ApS en la consecución de las metas planteadaspor la EpD. Esta vinculación no sólo repercute en la mejora substancial de la prácticade ambas creando sinergias positivas, sino que su universalización constituye unaclara incidencia positiva en el…

Global urban environmental change drives adaptation in white clover

2022

Made available in DSpace on 2022-04-28T19:52:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-18 Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied am…

Population divergence in maternal investment and embryo energy use and allocation suggests adaptive responses to cool climates

2023

1. The thermal sensitivity of early life stages can play a fundamental role in constraining species distributions. For egg-laying ectotherms, cool temperatures often extend development time and exacerbate developmental energy cost. Despite these costs, egg laying is still observed at high latitudes and altitudes. How embryos overcome the developmental constraints posed by cool climates is crucial knowledge for explaining the persistence of oviparous species in such environments and for understanding thermal adaptation more broadly. 2. Here, we studied maternal investment and embryo energy use and allocation in wall lizards spanning altitudinal regions, as potential mechanisms that enable su…

Discovery of a new class of sortase a transpeptidase inhibitors to tackle gram-positive pathogens: 2-(2-phenylhydrazinylidene)alkanoic acids and rela…

2016

A FRET-based random screening assay was used to generate hit compounds as sortase A inhibitors that allowed us to identify ethyl 3-oxo-2-(2-phenylhydrazinylidene)butanoate as an example of a new class of sortase A inhibitors. Other analogues were generated by changing the ethoxycarbonyl function for a carboxy, cyano or amide group, or introducing substituents in the phenyl ring of the ester and acid derivatives. The most active derivative found was 3-oxo-2-(2-(3,4dichlorophenyl)hydrazinylidene)butanoic acid (2b), showing an IC50 value of 50 µM. For a preliminary assessment of their antivirulence properties the new derivatives were tested for their antibiofilm activity. The most active compo…
