An empirical investigation of the relationship between integration, dynamic capabilities and performance in supply chains
This research aimed to develop an empirical understanding of the relationships between integration,
dynamic capabilities and performance in the supply chain domain, based on which, two conceptual
frameworks were constructed to advance the field. The core motivation for the research was that, at
the stage of writing the thesis, the combined relationship between the three concepts had not yet
been examined, although their interrelationships have been studied individually.
To achieve this aim, deductive and inductive reasoning logics were utilised to guide the qualitative
study, which was undertaken via multiple case studies to investigate lines of enquiry that would
address the research questions formulated. This is consistent with the author’s philosophical
adoption of the ontology of relativism and the epistemology of constructionism, which was considered
appropriate to address the research questions. Empirical data and evidence were collected, and
various triangulation techniques were employed to ensure their credibility. Some key features of
grounded theory coding techniques were drawn upon for data coding and analysis, generating two
levels of findings. These revealed that whilst integration and dynamic capabilities were crucial in
improving performance, the performance also informed the former. This reflects a cyclical and
iterative approach rather than one purely based on linearity. Adopting a holistic approach towards
the relationship was key in producing complementary strategies that can deliver sustainable supply
chain performance.
The research makes theoretical, methodological and practical contributions to the field of supply
chain management. The theoretical contribution includes the development of two emerging
conceptual frameworks at the micro and macro levels. The former provides greater specificity, as it
allows meta-analytic evaluation of the three concepts and their dimensions, providing a detailed
insight into their correlations. The latter gives a holistic view of their relationships and how they are
connected, reflecting a middle-range theory that bridges theory and practice. The methodological
contribution lies in presenting models that address gaps associated with the inconsistent use of
terminologies in philosophical assumptions, and lack of rigor in deploying case study research
methods. In terms of its practical contribution, this research offers insights that practitioners could
adopt to enhance their performance. They can do so without necessarily having to forgo certain
desired outcomes using targeted integrative strategies and drawing on their dynamic capabilities
Bildung in der digitalen Transformation
Die Coronapandemie und der durch sie erzwungene zeitweise Übergang von Präsenz- zu Distanzlehre haben die Digitalisierung des Bildungswesens enorm vorangetrieben. Noch deutlicher als vorher traten dabei positive wie negative Aspekte dieser Entwicklung zum Vorschein. Während den Hochschulen der Wechsel mit vergleichsweise geringen Reibungsverlusten gelang, offenbarten sich diese an Schulen weitaus deutlicher. Trotz aller Widrigkeiten erscheint eines klar: Die zeitweisen Veränderungen werden Nachwirkungen zeigen. Eine völlige Rückkehr zum Status quo ante ist kaum noch vorstellbar. Zwei Fragen bestimmen vor diesem Hintergrund die Doppelgesichtigkeit des Themas der 29. Jahrestagung der Gesellschaft für Medien in der Wissenschaft (GMW). Erstens: Wie ‚funktioniert‘ Bildung in der sich derzeit ereignenden digitalen Transformation und welche Herausforderungen gibt es? Und zweitens: Befindet sich möglicherweise Bildung selbst in der Transformation? Beiträge zu diesen und weiteren Fragen vereint der vorliegende Tagungsband
Using Crowd-Based Software Repositories to Better Understand Developer-User Interactions
Software development is a complex process. To serve the final software product to the end user, developers need to rely on a variety of software artifacts throughout the development process. The term software repository used to denote only containers of source code such as version control systems; more recent usage has generalized the concept to include a plethora of software development artifact kinds and their related meta-data.
Broadly speaking, software repositories include version control systems, technical documentation, issue trackers, question and answer sites, distribution information, etc. The software repositories can be based on a specific project (e.g., bug tracker for Firefox), or be crowd-sourced (e.g., questions and answers on technical Q&A websites). Crowd-based software artifacts are created as by-products of developer-user interactions which are sometimes referred to as communication channels. In this thesis, we investigate three distinct crowd-based software repositories that follow different models of developer-user interactions. We believe through a better understanding of the crowd-based software repositories, we can identify challenges in software development and provide insights to improve the software development process.
In our first study, we investigate Stack Overflow. It is the largest collection of programming related questions and answers. On Stack Overflow, developers interact with other developers to create crowd-sourced knowledge in the form of questions and answers. The results of the interactions (i.e., the question threads) become valuable information to the entire developer community. Prior research on Stack Overflow tacitly assume that questions receives answers directly on the platform and no need of interaction is required during the process. Meanwhile, the platform allows attaching comments to questions which forms discussions of the question. Our study found that question discussions occur for 59.2% of questions on Stack Overflow. For discussed and solved questions on Stack Overflow, 80.6% of the questions have the discussion begin before the accepted answer is submitted. The results of our study show the importance and nuances of interactions in technical Q&A.
We then study dotfiles, a set of publicly shared user-specific configuration files for software tools. There is a culture of sharing dotfiles within the developer community, where the idea is to learn from other developers’ dotfiles and share your variants. The interaction of dotfiles sharing can be viewed as developers sources information from other developers, adapt the information to their own needs, and share their adaptations back to the community. Our study on dotfiles suggests that is a common practice among developers to share dotfiles where 25.8% of the most stared users on GitHub have a dotfiles repository. We provide a taxonomy of the commonly tracked dotfiles and a qualitative study on the commits in dotfiles repositories. We also leveraged the state-of-the-art time-series clustering technique (K-shape) to identify code churn pattern for dotfile edits. This study is the first step towards understanding the practices of maintaining and sharing dotfiles.
Finally, we study app stores, the platforms that distribute software products and contain many non-technical attributes (e.g., ratings and reviews) of software products. Three major stakeholders interacts with each other in app stores: the app store owner who governs the operation of the app store; developers who publish applications on the app store; and users who browse and download applications in the app store. App stores often provide means of interaction between all three actors (e.g., app reviews, store policy) and sometimes interactions with in the same actor (e.g., developer forum). We surveyed existing app stores to extract key features from app store operation. We then labeled a representative set of app store collected by web queries. K-means is applied to the labeled app stores to detect natural groupings of app stores. We observed a diverse set of app stores through the process. Instead of a single model that describes all app stores, fundamentally, our observations show that app stores operates differently. This study provide insights in understanding how app stores can affect software development.
In summary, we investigated software repositories containing software artifacts created from different developer-user interactions. These software repositories are essential for software development in providing referencing information (i.e., Stack Overflow), improving development productivity (i.e., dotfiles), and help distributing the software products to end users (i.e., app stores)
Tourism and heritage in the Chornobyl Exclusion Zone
Tourism and Heritage in the Chornobyl Exclusion Zone (CEZ) uses an ethnographic lens to explore the dissonances associated with the commodification of Chornobyl's heritage.
The book considers the role of the guides as experience brokers, focusing on the synergy between tourists and guides in the performance of heritage interpretation. Banaszkiewicz proposes to perceive tour guides as important actors in the bottom-up construction of heritage discourse contributing to more inclusive and participatory approach to heritage management. Demonstrating that the CEZ has been going through a dynamic transformation into a mass tourism attraction, the book offers a critical reflection on heritagisation as a meaning-making process in which the resources of the past are interpreted, negotiated, and recognised as a valuable legacy. Applying the concepts of dissonant heritage to describe the heterogeneous character of the CEZ, the book broadens the interpretative scope of dark tourism which takes on a new dimension in the context of the war in Ukraine.
Tourism and Heritage in the Chornobyl Exclusion Zone argues that post-disaster sites such as Chornobyl can teach us a great deal about the importance of preserving cultural and natural heritage for future generations. The book will be of interest to academics and students who are engaged in the study of heritage, tourism, memory, disasters and Eastern Europe
Sport team leadership coaching and captaincy in elite level rugby union football
A wide range of literature exists on coaching but it is concerned predominantly with the high school and college levels, is based upon athlete or coach perceptions, or is confined to observations of training or competition. As leaders of sports teams, coaches and captains have rarely been studied at the highest level of national or international sports competition.
In the present study, the team leadership roles of the coach and captain in elite rugby union football in New Zealand were examined using participant observation and other qualitative research methods. Elite was defined as New Zealand rugby’s highest internal level of competition: (a) the national provincial championships and (b) international test matches of the national team, the All Blacks.
The study explored the roles of the elite rugby coach and captain in vivo in a wide variety of team situations. It was felt that this could provide first-hand information on particular team leader behaviours, on what a coach and captain actually do, and how they are perceived by those around them. The main objective, however, was to use grounded theory techniques to create a model of elite rugby team leadership that might guide developmental programmes on such leadership.
The research phases undertaken were those of participant observation with a Provincial Team for five matches, a survey of provincial teams’ coaches and captains on their leadership associated with actual matches, three years’ participant observation with the All Blacks (including observation in eight test match weeks), multiple perspectives on elite team leadership from past rugby test players in New Zealand and overseas, and interviews with national team leaders in sports other than rugby.
Participant observation, interviews, questionnaires and document analysis generated data from the research settings. These data were considered in terms of symbolic interactionism and subjected to a grounded theory process. This led to a set of elite rugby team leadership categories and properties which, in turn, generated a comprehensive set of theoretical propositions.
The propositions became the basis for a model of elite rugby team leadership. This model was then considered as the basis for a programme to develop elite rugby team leaders. Significant aspects of the research findings which have not featured in previous research literature included the coach’s vision, team culture, centrality of the game plan, match week build-up, the importance of the captain’s playing example, the coach's ability to utilise teaching precepts, the coach’s personal qualities, and the need to develop and evaluate team leaders. The model, and the developmental programme principles emanating from it, are seen as relevant for developing elite level leaders in team sports other than rugby
Discourses of sexual violence: A critical analysis of the representation of victims and perpetrators on Twitter
Esta tesis investiga críticamente los recursos y patrones lingüísticos utilizados por los tuiteros para debatir sobre discursos de género y opresión patriarcal en relación con la violencia sexual. Este estudio tiene dos objetivos principales: 1) examinar los discursos e ideologías de los tuiteros respecto a la violencia sexual y cómo estos contribuyen a la negociación de las identidades de víctima-perpetrador, y 2) identificar el papel del lenguaje evaluativo en la (re)producción y resistencia de discursos e ideologías de género. Para ello, esta tesis toma como caso de estudio la controvertida nominación del juez asociado Brett Kavanaugh al Tribunal Supremo de los Estados Unidos. Tras hacerse pública su nominación, fue acusado de intento de violación por la Dra. Christine Blasey Ford. Sus alegaciones fueron seguidas por otras similares de otras dos mujeres. La nominación se convirtió en un tema de conversación importante en la red social Twitter, ya que los tuiteros utilizaron diferentes hashtags para expresar su apoyo u oposición a la nominación. La Dra. Ford también se convirtió en el blanco de agresiones verbales por parte de quienes apoyaban la candidatura. Sin embargo, sus alegaciones también fueron apoyadas por aquellos tuiteros que validaron su testimonio y, a su vez, provocaron el resurgimiento del hashtivismo feminista. Se compilaron dos corpus de tuits que contenían los hashtags #KavanaughConfirmation (N = 1.753.370 palabras) y #NoKavanaughConfirmation (N = 612.416 palabras) para analizarlos y compararlos en relación con los objetivos de este estudio. Los corpus se analizaron desde un enfoque de análisis del discurso asistido por corpus (ADAC) (Partington et al., 2013) que combinaba herramientas de lingüística de corpus con el Análisis Crítico del Discurso Feminista (ACFD) (Lazar, 2005, 2018) y la Teoría de la Valoración (2005). Los resultados sugieren que los tuiteros verbalizaron discursos relacionados con la violencia de género tanto para denunciar como para perpetuar la cultura de la violación y la opresión patriarcal en la sociedad estadounidense. Estos discursos contribuyeron a la negociación de las identidades de víctima y agresor, que eran inestables y fluidas según los grupos sociopolíticos de los tuiteros. Se mostró que los discursos antifeministas y patriarcales contribuyeron a la representación de AsJ Kavanaugh como una víctima política, retratando así a la Dra. Ford como una agresora política. Por el contrario, los discursos de veracidad y feminismo dieron credibilidad al testimonio de la Dra. Ford y se opusieron a la confirmación. A su vez, estos discursos retrataron a AsJ Kavanaugh como un mentiroso y un agresor sexual. Por otro lado, el análisis del lenguaje evaluativo reveló que en ambos corpus predominaban recursos valorativos negativos para transmitir evaluaciones inmorales y poco éticas y angustia emocional colectiva, lo que contribuyó aún más a la construcción inestable de las identidades de víctima y perpetrador. En definitiva, esta tesis proporciona información sobre las prácticas digitales de los tuiteros para debatir dinámicas de género y resistir/reproducir discursos patriarcales derivados de la cultura de la violación. Además, también demuestra la fructífera combinación de los métodos de la lingüística de corpus, el FCDA y la teoría de la valoración para el análisis de la violencia de género y los datos de los redes sociales.This thesis critically traces the linguistic resources and patterns deployed by tweeters to discuss gendered discourses and patriarchal oppression concerning sexual violence. There are two primary aims of this study: 1) to examine tweeters’ discourses and ideologies regarding sexual violence and how they contribute to the negotiation of victim-perpetrator identities, and 2) to identify the role of evaluative language in the (re)production and resistance of gendered discourses and ideologies. To do so, this thesis takes AsJ Brett Kavanaugh’s controversial nomination to the Supreme Court of the United States as a case study. After his nomination was made public, he was accused of attempted rape by Dr. Christine Blasey Ford. Her allegations were followed by similar claims from two more women. The nomination became a major topic on Twitter as tweeters used different hashtags to express (dis)affiliation. Dr. Ford also became the target of verbal aggression by those who supported his nomination. However, her claims were also supported by tweeters who validated her testimony and, in turn, sparked the re-emergence of hashtag feminism. Two corpora of tweets containing the hashtags #KavanaughConfirmation (N = 1,753,370 words) and #NoKavanaughConfirmation (N = 612,416 words) were compiled to analyze and compare each dataset in relation to the objectives of this study. The corpora were investigated from a corpus-assisted discourse analysis approach (Partington et al., 2013) which combined corpus linguistic tools with Feminist Critical Discourse Analysis (FCDA) (Lazar, 2005, 2018) and Appraisal Theory (2005). The findings suggest that tweeters invoked discourses relating to gender-based violence to both denounce and perpetuate rape culture and patriarchal oppression in American society. Such discourses contributed to the negotiation of the identities of victims and perpetrators, which were unstable and fluid depending on tweeters’ socio-political groups. Antifeminist and patriarchal discourses were found to contribute to the portrayal of AsJ Kavanaugh as a political victim, thus portraying Dr. Ford as a political aggressor. In contrast, discourses of veracity and feminism gave credibility to Dr. Ford’s testimony and opposed the confirmation. These discourses depicted AsJ Kavanaugh as a liar and a sexual aggressor. On the other hand, the analysis of evaluative language revealed that negative Appraisal resources predominated in both corpora to convey immoral and unethical evaluations and collective emotional distress, which further contributed to the unstable construction of victim-perpetrator identities. All in all, this thesis provides insights into tweeters’ digital practices to discuss gendered dynamics and resist/reproduce patriarchal discourses derived from rape culture. In addition, it also shows the fruitful combination of corpus linguistics methods, FCDA, and Appraisal Theory in the analysis of gender-based violence and social media data
Space, Imagination, and Story: Understanding how contemporary interactive stories are told
Storytelling is one of the foundations of humanity and a shared experience between humankind. However, at times, storytelling has resulted in an alienated audience that are treated as passive beings. This passive audience could be seen as part of a mass audience collective to whom authors could feed stories for mass consumption.
I argue that contemporary interactive storytelling enables the audience to have more power and control over the stories with which they engage. Here, the audience has a choice of which stories they wish to consume, an approach that requires further research. In this thesis, I examine how contemporary authors create and tell interactive stories. My research question is: How do authors utilise relationships between space, imagination, and narrative within contemporary interactive storytelling?
To answer this question, I conducted a close reading of the York-based project, People We Love, selected for its particular engagements with my chosen themes of space, imagination, and narrative. I collected further qualitative data via interviews with personnel closely associated with the People We Love project. I also conducted deductive literature research on topics related to my research question and explored secondary case studies of correlated story projects.
My findings present a new appreciation of the author as a creator not so much of a specific story, but of a platform on which the audience may interact to create unique story experiences. My findings also showcase how a reader or user may feature in a contemporary interactive narrative as an individual rather than within a mass collective. These findings boost further understanding of the authorship of interactive storytelling and how stories may be told between complex relationships of space, imagination and narrative
