    El presente emprendimiento social Access Technology tiene como prop贸sito resolver el problema de la baja cuota de empleabilidad de las personas con discapacidad (PCD) en la ciudad de Lima. De acuerdo con el Instituto Nacional de Estad铆stica e Inform谩tica, el 10.4% de los peruanos presentan alguna discapacidad (INEI, 2014, p. 9), y s贸lo el 39.6% tienen un trabajo (INEI, 2015). Sin embargo, el 40% percibe un salario menor a la remuneraci贸n m铆nima vital y el 73.2% trabaja en puestos no adaptados a sus necesidades (INEI, 2014). Esta iniciativa brindar谩 a las personas con dificultad para ver, moverse, y o铆r; acceder a una educaci贸n de calidad, para luego posicionarse en un puesto de trabajo en el sector tecnol贸gico. Se busca, de esta manera, lograr su independencia econ贸mica y mejorar su calidad de vida. Para ello se elabor贸 un programa de capacitaci贸n especializado (bootcamp), donde el alumno podr谩 formarse en uno de los siguientes perfiles: ux/ui designer, front-end developer, back-end developer, big data analyst, y accessibility quality assurance tester. Access Technology es una soluci贸n innovadora, escalable, deseable, viable y sostenible. Ante todo, el estudiante podr谩 adquirir un cr茅dito estudiantil, realizar pr谩cticas y aplicar sus conocimientos en empresas de tecnolog铆a, y lograr, al finalizar el programa, un posicionamiento laboral en un plazo m谩ximo de seis meses. Segundo, la soluci贸n puede extenderse a otros departamentos del Per煤 y a otras poblaciones vulnerables, como personas LGTBI, de bajo recursos e inmigrantes. Por otro lado, el 83% de las PCD entrevistadas est谩n dispuestas a firmar un acuerdo estudiantil aceptando el costo del bootcamp. Asimismo, el emprendimiento proyecta un VAN que supera el $ 1麓000,000.00 y arroja un TIR de 44.95%. Finalmente, se puede decir que la propuesta es sostenible, debido a que impactar铆a la vida de m谩s de 2,000 PCD, los cuales formar谩n parte de la poblaci贸n econ贸micamente activa (PEA), y a la vez incidir谩 en dos objetivos de desarrollo sostenible (ODS).Access Technology is a social entrepreneurship that solves the problem of low employability rate of people with disabilities (PWD) in the city of Lima. According to the National Institute of Statistics and Informatics (INEI), 10.4% of Peruvians have some type of disability (INEI, 2014, p. 9) and only 39.6% of that group has a job (INEI, 2015). However, 40% of workers receive a salary lower than the national living wage and 73.2% work in positions that are not adapted to their needs (INEI, 2014). This initiative will provide PWD (with vision, moving, walking, and hearing disabilities) access to quality education and a chance to apply for a job in the technology sector. Thereby, they will be able to achieve their economic independence and improve their quality of life. To achieve this, a specialized training program (bootcamp) in technology is created. This is where the student will become a specialist in one of the following profiles: ux/ui designer, front-end developer, back end developer, and accessibility quality assurance tester. There are many reasons to explain why Access Technology is an innovative, desirable, viable and sustainable solution. Firstly, PWCD will be able to acquire a student loan, carry out an internship and apply their knowledge in technology companies during their training. They will then prepare and assume a job position within a maximum period of 6 months. This is a scalable and exponential initiative because model businesses can extend to other regions of Peru and more vulnerable populations. Secondly, 83% of the PWD interviewed are willing to sign a student agreement accepting the cost of the bootcamp. Thirdly, the project has a VANF that exceeds one million dollars in the eighth year, and a TIRF of 44.95%. Finally, it will impact the lives of 2,548 PWD since they will be part of the economically active population (EAP), and at the same time it will impact on 2 Sustainable Development Goals (SDGs)

    Does international patent collaboration have an effect on entrepreneurship?

    .Entrepreneurship is one of the main pillars of growth in any economy. Achieving a high rate of entrepreneurship in a region has become the priority objective of governments and firms. However, in many cases, new firm creation is conditioned by relations or collaboration in innovation with agents from other countries. Previous literature has analyzed the mechanisms that foster entrepreneurship. This paper attempts to shed light on the influence of international patent collaboration (IPC) on entrepreneurial activity at country level taking into account the timing of this relationship. An empirical study is proposed to verify whether IPC leads to greater entrepreneurship and to analyze the gestation period between international patenting actions and firm creation. Using the Generalized Method of Moments, the two hypotheses proposed were tested in a data panel of 30 countries for the period 2005鈥2017. Results show the influence of IPC in promoting entrepreneurship in the same year, but especially in the following year. The study offers implications for entrepreneurs and public agents. IPC affects the integration and interaction of international agents in a country, favors the production of new knowledge, and increases positive externalities in a territory. All this facilitates the creation of new companies with a high innovative component.S

    Get PDF
    .The increasing concern of consumers about food quality and safety and their rejection of chemical additives has promoted the breakthrough of the biopreservation field and the development of studies on the use of beneficial bacteria and their metabolites as potential natural antimicrobials for shelf life extension and enhanced food safety. Control of foodborne pathogens in meat and meat products represents a serious challenge for the food industry which can be addressed through the intelligent use of bio-compounds or biopreservatives. This article aims to systematically review the available knowledge about biological strategies based on the use of lactic acid bacteria to control the proliferation of undesirable microorganisms in different meat products. The outcome of the literature search evidenced the potential of several strains of lactic acid bacteria and their purified or semi-purified antimicrobial metabolites as biopreservatives in meat products for achieving longer shelf life or inhibiting spoilage and pathogenic bacteria, especially when combined with other technologies to achieve a synergistic effect.S

    .E-sports games can drive the sports industry forward and sponsorship is the best way to engage consumers of this new sport. The purpose of this study is to examine the effect of sponsorship image and consumer participation in co-creation consumption activities on fans鈥 sponsorship response (represented by the variables interest, purchase intention and word of mouth) in e-sports. Four antecedent variables build sponsorship image (i.e., ubiquity of sport, sincerity of sponsor, attitude to sponsor and team identification). A quantitative approach is used for the purposes of this study. Some 445 questionnaires were filled in by fans who watch e-sports in Spain; these are analyzed using partial least squares structural equation modeling (PLS-SEM). The outcomes show that sponsor antecedents are crucial factors if a sponsor wants to change their sponsorship image and influence sponsorship response, and that it is also possible to use participation to improve responsesS

    Metaphors of London fog, smoke and mist in Victorian and Edwardian Art and Literature

    Get PDF
    Julian Wolfreys has argued that after 1850 writers employed stock images of the city without allowing them to transform their texts. This thesis argues, on the contrary, that metaphorical uses of London fog were complex and subtle during the Victorian and Edwardian periods, at least until 1914. Fog represented, in particular, formlessness and the dissolution of boundaries. Examining the idea of fog in literature, verse, newspaper accounts and journal articles, as well as in the visual arts, as part of a common discourse about London and the state of its inhabitants, this thesis charts how the metaphorical appropriation of this idea changed over time. Four of Dickens's novels are used to track his use of fog as part of a discourse of the natural and unnatural in individual and society, identifying it with London in progressively more negative terms. Visual representations of fog by Constable, Turner, Whistler, Monet, Markino, O'Connor, Roberts and Wyllie and Coburn showed an increasing readiness to engage with this discourse. Social tensions in the city in the 1880s were articulated in art as well as in fiction. Authors like Hay and Barr showed the destruction of London by its fog because of its inhabitants' supposed degeneracy. As the social threat receded, apocalyptic scenarios gave way to a more optimistic view in the work of Owen and others. Henry James used fog as a metaphorical representation of the boundaries of gendered behaviour in public, and the problems faced by women who crossed them. The dissertation also examines fog and individual transgression, in novels and short stories by Lowndes, Stevenson, Conan Doyle and Joseph Conrad. After 1914, fog was no more than a crude signifier of Victorian London in literature, film and, later, television, deployed as a cliche instead of the subtle metaphorical idea discussed in this thesis

    Towards a sociology of conspiracy theories: An investigation into conspiratorial thinking on D枚nmes

    Get PDF
    This thesis investigates the social and political significance of conspiracy theories, which has been an academically neglected topic despite its historical relevance. The academic literature focuses on the methodology, social significance and political impacts of these theories in a secluded manner and lacks empirical analyses. In response, this research provides a comprehensive theoretical framework for conspiracy theories by considering their methodology, political impacts and social significance in the light of empirical data. Theoretically, the thesis uses Adorno's semi-erudition theory along with Girardian approach. It proposes that conspiracy theories are methodologically semi-erudite narratives, i.e. they are biased in favour of a belief and use reason only to prove it. It suggests that conspiracy theories appear in times of power vacuum and provide semi-erudite cognitive maps that relieve alienation and ontological insecurities of people and groups. In so doing, they enforce social control over their audience due to their essentialist, closed-to-interpretation narratives. In order to verify the theory, the study analyses empirically the social and political significance of conspiracy theories about the D枚nme community in Turkey. The analysis comprises interviews with conspiracy theorists, conspiracy theory readers and political parties, alongside a frame analysis of the popular conspiracy theory books on D枚nmes. These confirm the theoretical framework by showing that the conspiracy theories are fed by the ontological insecurities of Turkish society. Hence, conspiracy theorists, most readers and some political parties respond to their own ontological insecurities and political frustrations through scapegoating D枚nmes. Consequently, this work shows that conspiracy theories are important symptoms of society, which, while relieving ontological insecurities, do not provide politically prolific narratives

    Iam hiQ鈥攁 novel pair of accuracy indices for imputed genotypes

    Get PDF
    Background Imputation of untyped markers is a standard tool in genome-wide association studies to close the gap between directly genotyped and other known DNA variants. However, high accuracy with which genotypes are imputed is fundamental. Several accuracy measures have been proposed and some are implemented in imputation software, unfortunately diversely across platforms. In the present paper, we introduce Iam hiQ, an independent pair of accuracy measures that can be applied to dosage files, the output of all imputation software. Iam (imputation accuracy measure) quantifies the average amount of individual-specific versus population-specific genotype information in a linear manner. hiQ (heterogeneity in quantities of dosages) addresses the inter-individual heterogeneity between dosages of a marker across the sample at hand. Results Applying both measures to a large case鈥揷ontrol sample of the International Lung Cancer Consortium (ILCCO), comprising 27,065 individuals, we found meaningful thresholds for Iam and hiQ suitable to classify markers of poor accuracy. We demonstrate how Manhattan-like plots and moving averages of Iam and hiQ can be useful to identify regions enriched with less accurate imputed markers, whereas these regions would by missed when applying the accuracy measure info (implemented in IMPUTE2). Conclusion We recommend using Iam hiQ additional to other accuracy scores for variant filtering before stepping into the analysis of imputed GWAS data

    Iron oxide and water paste rheology and its effect on low adhesion in the wheel/rail interface

    Get PDF
    The 鈥渨et-rail鈥 phenomenon results in low adhesion between wheel and rail throughout the year, occurring transiently on a slightly wet, or drying railhead. It has been previously proposed that it is caused by a mixture of iron oxides and small amounts of water (from dew or precipitation) on the railhead that form a friction reducing paste. This paper outlines a novel combination of rheology, modelling and experimental work using a twin disc test rig to determine how the rheology of this iron oxide paste affects adhesion. The yield strength of different types of iron oxides, along with solid oxide fraction of the friction reducing paste, was assessed and used as an input into an 鈥渁dhesion model鈥 for assessing water and oxide suspensions. The rheological and modelling results were compared against very low adhesion recorded in twin disc experimental validation when simulating the wet-rail phenomenon
