Crowdfunding of Small Entrepreneurial Ventures

Abstract: An inherent problem that entrepreneurs face at the very beginning of their entrepreneurial initiative is to attract outside capital, given the lack of collateral and sufficient cash flows and the presence of significant information asymmetry with investors. Recently, some entrepreneurs have started to rely on the Internet to directly seek financial help from the general public (the “crowd”) instead of approaching financial investors such as business angels, banks or venture capital funds. This technique, called “crowdfunding”, has made possible to seek capital for project-specific investments as well as for starting up new ventures. In this book chapter (forthcoming in the Handbook of Entrepreneurial Finance at Oxford University Press), we discuss crowdfunding as an alternative way of financing projects, with a focus on small, entrepreneurial ventures. We provide a description of crowdfunding and discusses existing research on the topic, putting crowdfunding into perspective of entrepreneurial finance and thereby describing factors affecting entrepreneurial preferences for crowdfunding as source of finance. We elaborate different business models used to raise money from the crowd, in particular with respect to the structure of the crowdfunding process. Building on this discussion, we present and discuss extensively a case study, namely Media No Mad (a French startup). Finally we conclude with recommendations for entrepreneurs seeking to make use of crowdfunding and with suggestions for researchers about yet unexplored avenues of research.

The Human Phenotype Ontology in 2017

Abstract: Deep phenotyping has been defined as the precise and comprehensive analysis of phenotypic abnormalities in which the individual components of the phenotype are observed and described. The three components of the Human Phenotype Ontology (HPO; www.human-phenotype-ontology.org) project are the phenotype vocabulary, disease-phenotype annotations and the algorithms that operate on these. These components are being used for computational deep phenotyping and precision medicine as well as integration of clinical data into translational research. The HPO is being increasingly adopted as a standard for phenotypic abnormalities by diverse groups such as international rare disease organizations, registries, clinical labs, biomedical resources, and clinical software tools and will thereby contribute toward nascent efforts at global data exchange for identifying disease etiologies. This update article reviews the progress of the HPO project since the debut Nucleic Acids Research database article in 2014, including specific areas of expansion such as common (complex) disease, new algorithms for phenotype driven genomic discovery and diagnostics, integration of cross-species mapping efforts with the Mammalian Phenotype Ontology, an improved quality control pipeline, and the addition of patient-friendly terminology.

Agency and learning in the lifecourse: Towards an ecological perspective

Abstract: This paper is a contribution to understanding the relationship between agency and learning in the lifecourse. The contribution is mainly of a theoretical and a conceptual nature in that a particular notion of agency is used that enables agency to be conceived as something that is achieved, rather than possessed, through the active engagement of individuals with aspects of their contexts-for-action. We refer to this as an ecological understanding of agency. On the part of the actor, such engagements are characterised by particular configurations of routine, purpose and judgement. The argument is made that learning about the particular composition of one's agentic orientations and how they play out in one's life can play an important role in the achievement of agency, and that life-narratives, stories about one's life, can be an important vehicle for such learning. We explore the potential of this approach through a discussion of aspects of the learning (auto-) biographies of two participants in the...

Simultaneous Wireless Information and Power Transfer (SWIPT): Recent Advances and Future Challenges

Abstract: Initial efforts on wireless power transfer (WPT) have concentrated toward long-distance transmission and high power applications. Nonetheless, the lower achievable transmission efficiency and potential health concerns arising due to high power applications, have caused limitations in their further developments. Due to tremendous energy consumption growth with ever-increasing connected devices, alternative wireless information and power transfer techniques have been important not only for theoretical research but also for the operational costs saving and for the sustainable growth of wireless communications. In this regard, radio frequency energy harvesting (RF-EH) for a wireless communications system presents a new paradigm that allows wireless nodes to recharge their batteries from the RF signals instead of fixed power grids and the traditional energy sources. In this approach, the RF energy is harvested from ambient electromagnetic sources or from the sources that directionally transmit RF energy for EH purposes. Notable research activities and major advances have occurred over the last decade in this direction. Thus, this paper provides a comprehensive survey of the state-of-art techniques, based on advances and open issues presented by simultaneous wireless information and power transfer (SWIPT) and WPT assisted technologies. More specifically, in contrast to the existing works, this paper identifies and provides a detailed description of various potential emerging technologies for the fifth generation communications with SWIPT/WPT. Moreover, we provide some interesting research challenges and recommendations with the objective of stimulating future research in this emerging domain.

AndroZoo: collecting millions of Android apps for the research community

Abstract: We present a growing collection of Android Applications col-lected from several sources, including the official GooglePlay app market. Our dataset, AndroZoo, currently contains more than three million apps, each of which has beenanalysed by tens of different AntiVirus products to knowwhich applications are detected as Malware. We provide thisdataset to contribute to ongoing research efforts, as well asto enable new potential research topics on Android Apps.By releasing our dataset to the research community, we alsoaim at encouraging our fellow researchers to engage in reproducible experiments.
