Universal Design of Information Sharing Tools for Disaster Risk Reduction
2019
International audience; Disaster information sharing tools are an important aspect of disaster resilience, and it is of utmost importance that these tools are accessible and usable for as many potential users as possible. In this paper, we evaluate the accessibility of a selection of tools for crowdsourcing disaster situation information. As our evaluation shows that the selected tools are not fully accessible, we provide recommendations for mitigation, as well as highlight the importance of further research in this area.
Análisis de las plataformas de crowdfunding social en el estado español: un estudio de casos
2018
Las actuales tecnologías de la información y comunicación han propiciado un incremento en la capacidad de agrupación virtual de la sociedad, a través de la generación de un nutrido y variado conjunto de espacios de colaboración y participación comunicativa. Ello ha generado un nuevo marco de oportunidades de fundraising para el Tercer Sector de acción social español, frente al progresivo deterioro experimentado en su financiación tradicional a raíz de la crisis económica. Un nuevo marco donde se encuentra una herramienta con potencial para reconfigurar cualitativamente las estructuras de fundraising de las entidades sociales, dando cabida a una democratización financiera desde su propia bas…
Resistance to Change in the Corporate Elite
2017
In this empirical study, we investigate the variation in firms’ response to institutional pressure for gender-balanced boards, focusing specifically on the preservation of prevailing practices of director selection and its impact on the representation of women on the board of directors. Using 8 years of data from publicly listed Nordic corporations, we show societal pressure to be one of the determinants of female directorship. Moreover, in some corporations, the director selection process may work to maintain “a traditional type of board”. In such boards, demographic diversity among male members appears to be associated with a lower share of female directors, although we cannot establish w…
Crowding-out effect and sorting in competitive labour markets with motivated workers
2018
ABSTRACTThis article makes a contribution to the economics literature by inducing proper self-selection into contracts based on workers’ motivation. The novelty of our results is that it points out the alternative potential role of the crowding-out effect to separate workers based on their motivation.
Bubbles and Crowding-in of Capital via a Savings Glut
2017
This paper uncovers a mechanism by which bubbles crowd in capital investment. If capital formation is initially depressed by a binding credit constraint, a bubble triggers a savings glut. Higher returns in a new bubbly equilibrium attract additional savings, which are channeled to expand investment at the extensive margin, leading to permanently higher capital, output, and wages. We demonstrate that crowding-in through this channel is a robust phenomenon that occurs along the entire time path.
CROWDFUNDING AND INNOVATION
2018
Entrepreneurs have started relying on crowdfunding to fund their investments. This paper surveys the literature linking crowdfunding with innovation in entrepreneurial firms. Two distinct areas are discussed. First, crowdfunding has the potential to foster innovation by offering new sources of capital to innovation‐driven firms and thereby reduce the funding gap for innovative startups. Second, crowdfunding offers a way for the crowd to participate in the innovation process by providing feedback to the entrepreneur. This feedback can take various forms, including providing ideas on the development of the product during and after the campaign (in the spirit of crowdsourcing), and providing v…
On the drivers of successful crowdfunding: The case of the platform Verkami
2021
This article analyzes the determinants of successful crowdfunding initiatives using a sample of 5,251 projects from the reward-based Spanish platform Verkami. In contrast to most of the literature that has measured success with a dichotomous variable, we approach success with a continuous one, namely the ratio of achievement, which is measured as the obtained resources over the total amount requested by the promoter. We consider a set of potential determinants of success, which are theoretically well-grounded and cover a variety of spheres related to project features. Results suggest that factors related to the signaling theories such as partnership, having previous experience and interact…
Metabolic Adaptation and Protein Complexes in Prokaryotes.
2012
Protein complexes are classified and have been charted in several large-scale screening studies in prokaryotes. These complexes are organized in a factory-like fashion to optimize protein production and metabolism. Central components are conserved between different prokaryotes; major complexes involve carbohydrate, amino acid, fatty acid and nucleotide metabolism. Metabolic adaptation changes protein complexes according to environmental conditions. Protein modification depends on specific modifying enzymes. Proteins such as trigger enzymes display condition-dependent adaptation to different functions by participating in several complexes. Several bacterial pathogens adapt rapidly to intrace…
Comparing Different Crowd Emergency Evacuation Models Based on Human Centered Sensing Criteria
2014
Emergency evacuation of crowds is a fascinating phenomenon that has attracted researchers from various fields. Better understanding of this class of crowd behavior opens up for improving evacuation policies and smarter design of buildings, increasing safety. Recently, a new class of disruptive technology has appeared: Human-centered sensing which allows crowd behavior to be monitored in real-time, and provides the basis for real-time crowd control. The question then becomes: to what degree can previous crowd models incorporate this development, and what areas need further research? In this paper, the authors provide a survey that describes some widely used crowd models and discuss the advan…
Financing Small Businesses: From Venture Capital to Crowdfunding
2017
Abstract Startups and small businesses are facing many challenges in terms of financing their activities. These types of companies do not have the possibility to access capital market or to make IPO or to borrow money from banks like big, mature or well-known companies (who were at their beginnings startups or small businesses). They have to find different sources for financing their ideas/products/services that are in many cases very risky, hazardous or to ambitious. But, fortunately, the financing alternative for these companies have evolved during the last post crisis years. They have possibility to find some investors that are willing to invest in a non-name company by accessing crowdfu…
