    27306Este trabajo analiza el impacto del proceso de integración europea sobre el volumen de exportaciones de Castilla y León durante el período 1993-2007. La metodología utilizada se basa en la estimación de una ecuación de gravedad, que constituye una herramienta útil en la modelización de los flujos de comercio bilateral. Tras aplicar un análisis de datos de panel, los resultados indican que la riqueza del país importador y de Castilla y León, así como la distancia entre ellos, son las variables básicas de la ecuación de gravedad que mejor explican el flujo exportador analizado. Respecto a los distintos acontecimientos vinculados al proceso de integración europea, nuestros hallazgos ponen de manifiesto que ni la pertenencia del país importador a la UE, ni el hecho de compartir una moneda común, han ejercido un impacto favorable significativo sobre la cifra de exportaciones de Castilla y León.S

    The effect of peer-to-peer (P2P) accommodations on the local economy: evidence from Madrid

    Get PDF
    This paper investigates the effect of P2P accommodations on the local economy of the city of Madrid. We find that the arrival of Airbnb has fostered food and beverage services. We exploit the exogenous variation created by the timing and the unequal distribution of Airbnb listings across the urban geography to identify its effects on the number and employment of food and beverage services. Using an instrumental variable strategy, we find positive effects on both the number of restaurants and their employees: an increase in ten Airbnb rooms in a given census tract translates to one more restaurant, and the same increase in a given neighbourhood generates nine new tourist-related employees. The results are robust to sample composition, spatial spillovers and alternative measures of tourist-related activities. This paper contributes to the literature on the economic impacts of the platform economy on urban areas by providing evidence of positive economic externalities from P2P accommodations

Sample Challenges at Moodle (126), Appendix H. Participants’ questionnaire results (128).La gamificación es un término que suele denotar el uso de componentes del juego en situaciones no relacionadas con el juego en sí para crear experiencias de aprendizaje agradables, divertidas y motivadoras para los estudiantes (Werbach y Hunter, 2012). Por lo tanto, el análisis de los factores básicos de los juegos se convierte en algo esencial a la hora de definir y utilizar la gamificación como estrategia de mediación del inglés como lengua extranjera para fortalecer rasgos específicos de pronunciación en los estudiantes de pregrado de la UPTC Sogamoso. El procedimiento de estudio se basa en la investigación acción mediante la implementación de la estrategia de gamificación para la mediación en la pronunciación del inglés, orientada a treinta estudiantes de diferentes programas de ingeniería, administración y tecnología con niveles heterogéneos de dominio del inglés. Las actividades se centran principalmente en la producción de sonidos, el ritmo, el acento y la entonación, los rasgos de pronunciación segmental y suprasegmental. Los resultados arrojaron una evidente mejora en las características segméntales y suprasegmentales de la percepción en la pronunciación de los participantes así como la contribución del objetivo de los juegos a la instrucción fonética y fonológica, la sensación en el juego a la motivación para mejorar la pronunciación, el reto establecido en los juegos a la actitud positiva de los participantes, y la sociabilidad a la exposición practica de la pronunciación inglesa.Gamification is a relatively new term that often denotes the use of game components in situations unrelated to the game itself to create enjoyable, fun, and motivating learning experiences for students (Werbach and Hunter, 2012). Therefore, analyzing the games' basic factors becomes essential when defining and using gamification as a strategy for English as Foreign Language mediation to strengthen specific pronunciation features in UPTC Sogamoso undergraduate students. The study procedure is based on action research by implementing the gamification strategy for mediation in English pronunciation, oriented to thirty students from different engineering, management, and technology programs at heterogeneous levels of English proficiency. The activities mainly focus on sound production, rhythm, stress, and intonation, segmental and suprasegmental pronunciation features. The results showed an evident improvement in the segmental and suprasegmental features of the participants' pronunciation perception as well as the contribution of game goals to phonetics and phonological instruction, the game sensation to the motivation for pronunciation improvement, the game challenge to the participants' positive attitude, and the sociality to the English pronunciation exposure practice

    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

    Biocontrol as a key component to manage brown rot on cherry

    Get PDF
    Brown rot, caused by Monilinia spp., is one of the most important diseases in stone fruits worldwide. Brown rot can cause blossom wilts and fruit rots in the orchard as well as latent infections of fruit, leading to post-harvest fruit decaying. Current control methods rely on scheduled spraying of fungicides. However, the continuing pressure to reduce fungicide use has seen an increase in research into alternative management methods, such as biological control. NIAB EMR recently identified two microbes that significantly reduced sporulation of Monilinia laxa under laboratory conditions. These two isolates were a bacterial species Bacillus subtilis (B91) and yeast-like fungus Aureobasidium pullulans (Y126) and are currently being formulated into commercial products. We are investigating how to optimise the use of these two potential biocontrol products in practice, in terms of suppressing Monilinia sporulation on overwintered mummies and preventing infection of blossoms and fruits. When applied to mummified fruits in winter Y126’s population was stable through the winter but at a low concentration. The B91 survived a little longer with the population reaching that of the control group by week 4. Neither Biological control (BCA) treatments had an affected the population of M. laxa when compared to the control treatment of sterile distilled water. The interaction time between the BCAs and M. laxa showed the longer the interaction time the lower the spore count of M. laxa. Another study was performed looking into the ability of our BCAs to colonise and survive on blossoms. B91 did not survive well on blossoms but could survive on fruits. However, its antagonistic compounds need to be in relatively high concentration to be effective against M. laxa. Therefore, it is best used as a fungicide, ensuring the antagonistic compounds are at a high concentration when applied in the field. Y126 can persist throughout the season and was marginally, though not statistically significantly, more effective at long term reduction in M. laxa. This could be because Y126 works through competition, therefore the interaction time with the pathogen could be important for efficacy and something worth investigating further. The difference between the BCAs highlights the need to understand each BCA’s ecology to ensure maximum efficacy. In a latent infection experiment, we inoculated trees with M. laxa and then treated them with the two biocontrol isolates two weeks before harvest. Post-harvest disease development was assessed after four days of storage in 2019 and two weeks in 2020. There was a significant reduction in rot incidence (p < 0.001) of 29% (Y126) and 27% (B91) in 2019 and 62 % (Y126) and 80 % (B91) in 2020 when the harvested fruit was stored at cold store levels. With new products to be introduced into the environment, it's important to understand the effects they may have on the plant's microbiome. Using next-generation sequencing techniques, we looked at the impact B91 and Y126 has on the blossom and cherry microbiomes. There was a treatment effect in both the bacterial and fungal communities on the blossom and ripe cherry. But the biggest variability was between blocks (Geographical effect) and between the years in which we experimented (p < 0.0001). This research will assist in the development of management strategies, especially spray timings for brown rot on stone fruit, integrating BCAs with other management practices

    How Does Reciprocity Affect Undergraduate Student Orientation towards Stakeholders?

    5987Nowadays, students are more aware of the impact of companies on their stakeholders and the need for properly handling their expectations to operationalize corporate social responsibility. Nevertheless, little is known about how certain individual traits may relate to their stance on the issue. This exploratory research contributes to stakeholder theory by analysing the e ect of the individual’s decision-making process, including the consideration of their social preferences, on their orientation toward stakeholder management. Here, we draw upon a theoretical model for resource-allocation decision-making consisting of reciprocal and non-reciprocal components. Our data, from undergraduate students enrolled in di erent degrees, were collected through a questionnaire and two social within-subject experiments (ultimatum and dictator games). Thus, our results show that the presence of a reciprocal component when decisions are made is positively linked to an instrumental orientation toward stakeholders. In addition, a greater non-reciprocal component in the decision-making process corresponds to a more normative orientation.S

    Women’s Experiences of Accessing Breastfeeding and Perinatal Health Support in the Context of Intimate Partner Violence: An Interpretive Description Study

    Background: Women experiencing intimate partner violence are at a heightened risk of negative perinatal and breastfeeding outcomes. This study explored the experiences of accessing breastfeeding support for women who endorse a history of intimate partner violence. A study of five in-depth semi-structured interviews were completed at 12-weeks postpartum with breastfeeding mothers with a history of intimate partner violence. Findings: Women expressed difficulties in accessing a healthcare provider who had specialized skill in breastfeeding support. Trust in their healthcare provider, built through displays of compassion and competence, was important to mitigate obstacles experienced during care access for this population. Trauma-and-violence-informed care principles were beneficial to the development of the therapeutic relationship in perinatal care. Women placed value on breastfeeding support received from both healthcare providers and social supports, which impacted mothers’ perceived breastfeeding support and self-efficacy. Further, mothers described increased levels of breastfeeding self-efficacy after engaging in a trauma-and-violence-informed care program aimed at supporting breastfeeding. Conclusions: Trauma-informed care may aid in the development of trust in the therapeutic relationship, which in turn impacts access to breastfeeding support and breastfeeding self-efficacy. The inclusion of trauma-and-violence informed principles in perinatal care may be effective at mitigating barriers to access for women who endorse a history of intimate partner violence. health care on how to employ trauma-informed breastfeeding care to may lead to better support for this population

    Sharing the Shore: Hybridity and Developing Environmentalisms in the Indiana Dunes

    Get PDF
    This thesis centers on the Indiana Dunes National Park, located in Northwestern Indiana, and the implications of this hybrid landscape on modern American environmentalism. Through secondary source research, historical analysis, and interviews with Miller Beach residents and a park ranger, this research concludes that the Indiana Dunes demonstrate an environmentalism that exists outside of the nature-culture binary. By incorporating the park into existing cities and industrial developments, the Indiana Dunes can be seen as a model for an environmental justice-driven space that diverges from the historic elitism of the National Park service. This research concludes that, while hybrid landscapes come with their own challenges, the hybridity of the Indiana Dunes ultimately points to a bright future for the National Park Service, one that makes public green space accessible and that radically rethinks what it means to be a National Park

    Blue Dog Blues: The Fall of the Blue Dog Democrats in the 2010 Midterms and the Future of Swing District Representation in a Nationalized Congress

    Get PDF
    Nationalization has defined American politics in recent years as voters increasingly view state and local government through their national party loyalties. The 2010 midterm elections were intensely nationalized: Hundreds of races for the United States House of Representatives focused on President Barack Obama’s agenda instead of local issues. After election night, Republicans gained 63 seats in the US House, giving them their largest majority since the 1940s. One of the political victims of the election were members of the Blue Dog Coalition, a caucus of centrist, fiscally conservative Democrats in Congress. Over half of the Blue Dogs lost re-election, including Stephanie Herseth Sandlin of South Dakota and Harry Mitchell of Arizona’s 5th District. In Congress: The Electoral Connection, congressional scholar David Mayhew outlines three re-election strategies that members of Congress pursue: credit claiming, advertising, and position taking. This thesis applies those three approaches to Sandlin and Mitchell’s races to argue that nationalization may increasingly pose a threat to traditional, swing district re-election strategies in the future; vulnerable incumbents may not be able to avoid national controversy as the significance of local political issues recede in the minds of American voters

    Interactive Sonic Environments: Sonic artwork via gameplay experience

    The purpose of this study is to investigate the use of video-game technology in the design and implementation of interactive sonic centric artworks, the purpose of which is to create and contribute to the discourse and understanding of its effectiveness in electro-acoustic composition highlighting the creative process. Key research questions include: How can the language of electro-acoustic music be placed in a new framework derived from videogame aesthetics and technology? What new creative processes need to be considered when using this medium? Moreover, what aspects of 'play' should be considered when designing the systems? The findings of this study assert that composers and sonic art practitioners need little or no coding knowledge to create exciting applications and the myriad of options available to the composer when using video-game technology is limited only by imagination. Through a cyclic process of planning, building, testing and playing these applications the project revealed advantages and unique sonic opportunities in comparison to other sonic art installations. A portfolio of selected original compositions, both fixed and open are presented by the author to complement this study. The commentary serves to place the work in context with other practitioners in the field and to provide compositional approaches that have been taken
