The consequences of regulation of desat1 expression for pheromone emission and detection in Drosophila melanogaster.
2010
AbstractSensory communication depends on the precise matching between the emission and the perception of sex- and species-specific signals; understanding both the coevolutionary process and the genes involved in both production and detection is a major challenge. desat1 determines both aspects of communication—a mutation in desat1 simultaneously alters both sex pheromone emission and perception in Drosophila melanogaster flies. We investigated whether the alteration of pheromonal perception is a consequence of the altered production of pheromones or if the two phenotypes are independently controlled by the same locus. Using several genetic tools, we were able to separately manipulate the tw…
Institut de Drets Humans
2007
L'Institut de Drets Humans de la Universitat de València naix en 2005 com a resposta a la demanda social que sol·licita una reflexió crítica entorn dels drets fonamentals en la societat democràtica. L'Institut està format per investigadors de diverses disciplines, amb una trajectòria àmplia i constant en la defensa, el reconeixement i l'anàlisi dels drets humans. El seu treball es desenvolupa en els àmbits de la docència, la investigació, i la divulgació. L'Institut participa en fòrums nacionals i internaci
Institut de Creativitat i Innovacions Educatives
2006
L'Institut de Creativitat i Innovacions Educatives s'estructura en dues seccions, la d'Innovacions Educatives i la d'Innovacions Estètiques, dedicades a la investigació, l'ensenyament teòric i pràctic, i l'assessorament a empreses i institucions, en els camps de l'educació i de l'estètica. L'Institut de-senvolupa una labor constant d'exploració de la realitat social, que ho ha convertit en un referent científic reconegut per a la presa de decisions que impulsen els avanços socials en els camps de l'educació
Evidencias de validez interna de un instrumento para evaluar la colegialidad docente
2019
Este estudio es parte de una investigación más amplia que busca diseñar un modelo de evaluación de los sistemas educativos basado en la mejora de la cohesión social. Se trata de un estudio de validación métrica de un instrumento de evaluación de la colegialidad docente. El instrumento se aplicó a partir de las conclusiones del estudio de validación por comités de expertos. La muestra estuvo formada por 147 profesores voluntarios de primaria y secundaria de España. La metodología utilizada se basó en la recogida de evidencias métricas de validez interna del instrumento; se estudió la dimensionalidad mediante el análisis factorial exploratorio y la capacidad de discriminación mediante el anál…
Firms’ investment, indebtedness and financial constraints: Size does matter
2022
Abstract This paper provides evidence of the importance of size in explaining the impact of financing conditions on firms´ investment rate. The study makes two main contributions: a) it allows the relationship between indebtedness and firms´ investment to be non-linear; and b) it contrasts whether the impact of indebtedness and the degree of financial restriction differ depending on the size of the company (SME vs large). Results show that while in SMEs indebtedness has a negative impact on investment, there is a threshold beyond which this effect is even larger (based on a debt/assets ratio of 59%). However, in large companies the impact of indebtedness is positive although there is also a…
Private–Public Partnerships as Strategic Alliances
2008
A new approach to the design of concession contracts of port infrastructures that adapts some of the methods used in the design and start-up of strategic alliances is presented. From a cost–benefit analysis of the project, based on the industry benchmarks, a revenue-sharing model dependent on the investment interest and the risk undertaken or transferred by each partner was formulated. This model aids in the calculation of the amount of the canons (lease and royalty charges) that should be stated in the contract. Also, to avoid complicated renegotiations and undesired deadlock situations, methods are presented for the dynamic actualization of such canons according to changes that might occ…
A Methodology to Detect the Deviations of the Project s Budget Compared to Market Prices
2015
[EN] The budget of a project reflects the cost of the investment needed to build an infrastructure, install a system or acquire new materials or supplies. A well-formulated budget in accordance with market prices, allows contractors to prepare offers according to their technical, economic and financial characteristics. On the other hand, it avoids current philosophies that aim to get the contract at any price. Philosophies subsequently used to point out problems and claims during the execution of the project (contradictory prices, delays, etc.) in order to recover some or the entire economic bid carried out during the tendering. In this paper a simple and fast methodology is developed to ch…
Corporate Investment, Debt and Liquidity Choices in the Light of Financial Constraints and Hedging Needs
2015
We examine firms' simultaneous choice of investment, debt financing and liquidity in a large sample of US corporates between 1980 and 2014. We partition the sample according to the firms' financial constraints and their needs to hedge against future shortfalls in operating income. In contrast to earlier work, our joint estimation approach shows that cash flows affect the corporate decisions of unconstrained firms more strongly than those of constrained firms. Investment-cash flow sensitivities are particularly intense for unconstrained firms with high hedging needs. Investment opportunities (as proxied by Q), however, play a larger role for constrained firms with the effects being strongest…
The influence of financial features and country characteristics on B2B ICOs’ website traffic
2021
Abstract Technology, blockchain, and initial coin offerings (ICOs) have changed the established ways of financing companies and doing business. The changes that affect organizational communications, specifically marketing communications, remain unclear, especially in the context of business-to-business (B2B) organizations. The current trend is for B2B companies to view social media as an optimal way to enhance lasting and valuable relationships with other companies. There is little research on social media marketing strategies by B2B organizations. To fill this gap, this study uses a sample of 57 B2B ICOs completed by December 2019 and qualitative comparative analysis to examine how the com…
On the Tail Risk of Cyberattacks in the Bitcoin Market
2020
In the era of digitalization, cryptocurrencies have become an alternative asset for both retail and institutional investors. While the new emerging digital ecosystem based on blockchain technology has been praised for offering plenty of advantages such as decentralization, discretion or increased efficiency in terms of faster settlements among others, investors need to be aware of new types of risks such as hacking incidents. In the 2011-2018 period, about 1.7 million unit of Bitcoin have been stolen corresponding to losses accumulating more than $655 million highlighting the societal impact of this criminal activity. The novel aspect of our study is that it employs a recently proposed appr…
