Digital collaborations and entrepreneurship – the role of shareconomy and crowdsourcing in the era of smart city

The thesis begins with the classical cooperation and transfers it to the digital world. This work gives a detailed overview of the young fields of research smart city, shareconomy and crowdsourcing and links these fields with entrepreneurship. The core research aim is the finding of connections between the research fields smart city, shareconomy and crowdsourcing and entrepreneurial activities and the specific fields of application, success factors and conditions for entrepreneurs. The thesis consists of seven peer-reviewed publications. Based on primary and secondary data, the existence of entrepreneurial opportunities in the fields of smart city, shareconomy and crowdsourcing could be confirmed. The first part (publications 1-3) of the thesis are literature reviews to secure the fundamental base for further research. This part consists of newly created definitions and an extreme sharpening of the research fields for the near future. In the second part of the thesis (publications 4-7), empirical field work (in-depth interviews with entrepreneurs) and quantitative analyses (fuzzy set/qualitative comparative analysis and binary logistic regression analysis) contribute to the field of research with additional new insights. Summarizing, the insights are multi-layered: theoretical (e.g. new definitions, sharpening of the research field), methodical (e.g. first time application of the fuzzy set/qualitative comparative analysis in the field of crowdfunding) and qualitative (first time application of in-depth interviews with entrepreneurs in the fields of smart city and shareconomy). The global research question could be answered: the link between entrepreneurship and smart city, shareconomy and crowdfunding could be confirmed, concrete fields of application could be identified and further developments could be touched upon. This work strongly contributes to the young fields of research through much-needed basic work, new qualitative approaches, innovative methods and new insights and offers opportunities for discussion, criticism and support for further research.

A City's Toys: Theatre in Birmingham 1914-1918

This chapter provides a wide-ranging account of theatre in Birmingham, the UK’s second largest city. As a vital centre for the production of mass armaments and vehicles essential for the war effort, Birmingham was home to a rapidly expanding and socially diverse population. I show how theatres overcame wartime constraints to reflect that diversity with examples drawn from the popular entertainment provided by the city’s music halls, variety and melodrama theatres contrasted with the more decorous touring plays, musicals and spectacular home-grown pantomimes enjoyed at the prestigious Theatre Royal and Prince of Wales. The dogged attempts by the recently-established Birmingham Repertory Theatre to sustain an artistically and intellectually ambitious programme of new and classic drama also reveal a more complex response to the effects of war.

The Janus-faced City: A Sensory History of the London Blitz 1940–1941

The city of London was, during the years of 1940–1941, a city under fire. The metropolis seemed to have two faces, like the Roman deity Janus: the face of the daylight hours, so normal, and yet so deceiving in its false quietness – and at nightfall, the city turned, and the face of it was the face of the devil himself, transforming London into a living inferno. This thesis examines the sensescapes of the Blitz, through the diaries and memoirs written of that time. The primary sources consist of seven different diaries, two autobiographies, and four research volumes that contain multiple diary- and memoire entries, mostly from the Mass Observation Archives and from the Imperial War Museum. The sensory approach is a new orientation in the field of history – it studies the five senses in their cultural contexts, interpreting the often subtle ways in which the senses affect into society, politics, culture, and class hierarchies, to name only but few. The subject of the sensory history of war is a theme widely unexamined: this thesis contributes to this frontier field by unveiling the sensorium of the London bombings, comparing the differences between the halves of nychtemeron, and examining how the Blitz was communicated by the writers as a lived, bodily experience. This study reveals the very different sensory worlds in which the Londoners lived, during a time that is often described with the mythical solidarity that was thought to exist between the people. The reality of the homeless, working class, and poor were in the foul smelling tubes, poor law -dated rations, and in the smoking ruins of East End – the contrast was massive reflecting it to the luxury hotels and restaurants of the upper classes, opportunities for evacuation, sheltering possibilities, and overall comforts of life.

Poéticas ficcionais e percursos imaginários em City of glass de Paul Auster

Nas três narrativas que constituem The New York Trilogy – City of Glass, Ghosts e The Locked Room – Paul Auster emprega e desconstrói os elementos convencionais do romance policial, elaborando uma investigação recorrente da natureza, função e significado da linguagem, mas também da solidão, do encerramento e da problemática da identidade. A produção narrativa de Auster evoca fantasmas logocêntricos tradicionais (como a presença, a realidade e a verdade), que fazem eco do princípio de indissolubilidade entre palavra e significado, apenas para lograr esta identidade através de uma orientação textual para a marcação da ficcionalidade e consequente reforço dos efeitos de significação ilusórios. Auster altera os mecanismos logrando as expectativas do leitor em relação ao epílogo e à transparência textual, que um pacto mimético faria pressupor. O espaço vazio resultante confere ao texto uma liberdade plurissignificativa que dispersa todas as certezas e veicula o poder da criação do caos. Sob a aparência de fluência narrativa, a escrita de Paul Auster esconde uma subversão das premissas básicas da literatura realista e dos signos referenciais, numa poética auto-reflexiva ficcionalizada sobre a estruturação de universos imaginários.

The New Jersey Meadowlands: Inhabiting an Urban Wilderness

The New Jersey Meadowlands is a thirty square mile industrial wetland between New York City and the commercial district of East Rutherford, NJ. The place is both strange and fascinating; many mysteries are hidden between the reed grasses and scattered garbage. Often exposed to subjectivity, the Meadowlands is commonly perceived as a weird, polluted, industrial, and even an other-worldly space; few know its beauty. These differing perceptions create a challenge when thinking of a cohesive identity and sense of place in the marsh. Over time, the once pure landscape has suffered from infrastructural slices, illegal dumping, and environmental abuse, resulting in fragmented land areas along the Hackensack River’s edge. This thesis explores how to inhabit an ecologically devalued and residual landscape through ideas of place-making and re-connecting communities. Investigating the paradox of this massive urban landscape and capitalizing on the ecological and educational potential of the site, lends also to a challenge of converging modern and forgotten life. Designing a place-based ecological research community within this currently placeless environment, will engage the public, re-connect lost communities, and bring a sense of renewal to the marsh.
