    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

    Gender Roles in Super Bowl Commercials: A Qualitative Longitudinal Content Analysis From 2013-2022

    Get PDF
    Although numerous studies have examined gender stereotypes in advertising, relatively few have investigated the communication of gender roles in Super Bowl commercials. The Super Bowl attracts the largest televised audience in the United States; thus, it holds the power to shape, influence, and reinforce attitudes and beliefs. Through a sociocultural lens, this qualitative study examines the communication of gender roles in Super Bowl commercials across a 10-year period from 2013 to 2022. Utilizing a longitudinal content analysis design, 279 Super Bowl advertisements from 2013, 2016, 2019, and 2022 were analyzed. The problem addressed is how the depiction of gender roles in Super Bowl commercials has changed over the past decade. The purpose of this qualitative longitudinal content analysis is to understand and explore how gender roles have changed in Super Bowl commercials from 2013 to 2022. Four research questions guided the study in which seven primary themes and 12 subthemes emerged. Key results include shifts in sexuality, role types, and product categories. Although many shifts occurred to varying degrees, traditional couples and family units continue to be communicated through heterosexual narratives. A significant number of commercials utilize the role of celebrity, comedic appeal, and elements of competition regardless of product type. Theoretically, the mirror argument and the mold argument are both at play. Six suggestions for future research are presented

    Operatic Pasticcios in 18th-Century Europe

    Get PDF
    In Early Modern times, techniques of assembling, compiling and arranging pre-existing material were part of the established working methods in many arts. In the world of 18th-century opera, such practices ensured that operas could become a commercial success because the substitution or compilation of arias fitting the singer's abilities proved the best recipe for fulfilling the expectations of audiences. Known as »pasticcios« since the 18th-century, these operas have long been considered inferior patchwork. The volume collects essays that reconsider the pasticcio, contextualize it, define its preconditions, look at its material aspects and uncover its aesthetical principles

    Human-Centered Approach to Technology to Combat Human Trafficking

    Human trafficking is a serious crime that continues to plague the United States. With the rise of computing technologies, the internet has become one of the main mediums through which this crime is facilitated. Fortunately, these online activities leave traces which are invaluable to law enforcement agencies trying to stop human trafficking. However, identifying and intervening with these cases is still a challenging task. The sheer volume of online activity makes it difficult for law enforcement to efficiently identify any potential leads. To compound this issue, traffickers are constantly changing their techniques online to evade detection. Thus, there is a need for tools to efficiently sift through all this online data and narrow down the number of potential leads that a law enforcement agency can deal with. While some tools and prior research do exist for this purpose, none of these tools adequately address law enforcement user needs for information visualizations and spatiotemporal analysis. Thus to address these gaps, this thesis contributes an empirical study of technology and human trafficking. Through in-depth qualitative interviews, systemic literature analysis, and a user-centered design study, this research outlines the challenges and design considerations for developing sociotechnical tools for anti-trafficking efforts. This work further contributes to the greater understanding of the prosecution efforts within the anti-trafficking domain and concludes with the development of a visual analytics prototype that incorporates these design considerations.Ph.D

    Tensors in statistics and rigidity theory

    This is a short report on the discussions of appearance of tensors in algebraic statistics and rigidity theory, during the semester ``AGATES: Algebraic Geometry with Applications to TEnsors and Secants". We briefly survey some of the existing results in the literature and further research directions. We first provide an overview of algebraic and geometric techniques in the study of conditional independence (CI) statistical models. We study different families of algebraic varieties arising in statistics. This includes the determinantal varieties related to CI statements with hidden random variables. Such statements correspond to determinantal conditions on the tensor of joint probabilities of events involving the observed random variables. We show how to compute the irreducible decompositions of the corresponding CI varieties, which leads to finding further conditional dependencies (or independencies) among the involved random variables. As an example, we show how these methods can be applied to extend the classical intersection axiom for CI statements. We then give a brief overview about secant varieties and their appearance in the study of mixture models. We focus on examples and briefly mention the connection to rigidity theory which will appear in the forthcoming paper \cite{rigidity}.Comment: Comments are welcome! arXiv admin note: substantial text overlap with arXiv:2103.1655

    Explaining Recommendation System Using Counterfactual Textual Explanations

    Currently, there is a significant amount of research being conducted in the field of artificial intelligence to improve the explainability and interpretability of deep learning models. It is found that if end-users understand the reason for the production of some output, it is easier to trust the system. Recommender systems are one example of systems that great efforts have been conducted to make their output more explainable. One method for producing a more explainable output is using counterfactual reasoning, which involves altering minimal features to generate a counterfactual item that results in changing the output of the system. This process allows the identification of input features that have a significant impact on the desired output, leading to effective explanations. In this paper, we present a method for generating counterfactual explanations for both tabular and textual features. We evaluated the performance of our proposed method on three real-world datasets and demonstrated a +5\% improvement on finding effective features (based on model-based measures) compared to the baseline method

    Klarnetin staccato tekniğini güçlendirme aşamaları eser çalışmalarıyla uygulanmıştır. Staccato geçişlerini hızlandıracak ritim ve nüans çalışmalarına yer verilmiştir. Çalışmanın en önemli amacı sadece staccato çalışması değil parmak-dilin eş zamanlı uyumunun hassasiyeti üzerinde de durulmasıdır. Staccato çalışmalarını daha verimli hale getirmek için eser çalışmasının içinde etüt çalışmasına da yer verilmiştir. Çalışmaların üzerinde titizlikle durulması staccato çalışmasının ilham verici etkisi ile müzikal kimliğe yeni bir boyut kazandırmıştır. Sekiz özgün eser çalışmasının her aşaması anlatılmıştır. Her aşamanın bir sonraki performans ve tekniği güçlendirmesi esas alınmıştır. Bu çalışmada staccato tekniğinin hangi alanlarda kullanıldığı, nasıl sonuçlar elde edildiği bilgisine yer verilmiştir. Notaların parmak ve dil uyumu ile nasıl şekilleneceği ve nasıl bir çalışma disiplini içinde gerçekleşeceği planlanmıştır. Kamış-nota-diyafram-parmak-dil-nüans ve disiplin kavramlarının staccato tekniğinde ayrılmaz bir bütün olduğu saptanmıştır. Araştırmada literatür taraması yapılarak staccato ile ilgili çalışmalar taranmıştır. Tarama sonucunda klarnet tekniğin de kullanılan staccato eser çalışmasının az olduğu tespit edilmiştir. Metot taramasında da etüt çalışmasının daha çok olduğu saptanmıştır. Böylelikle klarnetin staccato tekniğini hızlandırma ve güçlendirme çalışmaları sunulmuştur. Staccato etüt çalışmaları yapılırken, araya eser çalışmasının girmesi beyni rahatlattığı ve istekliliği daha arttırdığı gözlemlenmiştir. Staccato çalışmasını yaparken doğru bir kamış seçimi üzerinde de durulmuştur. Staccato tekniğini doğru çalışmak için doğru bir kamışın dil hızını arttırdığı saptanmıştır. Doğru bir kamış seçimi kamıştan rahat ses çıkmasına bağlıdır. Kamış, dil atma gücünü vermiyorsa daha doğru bir kamış seçiminin yapılması gerekliliği vurgulanmıştır. Staccato çalışmalarında baştan sona bir eseri yorumlamak zor olabilir. Bu açıdan çalışma, verilen müzikal nüanslara uymanın, dil atış performansını rahatlattığını ortaya koymuştur. Gelecek nesillere edinilen bilgi ve birikimlerin aktarılması ve geliştirici olması teşvik edilmiştir. Çıkacak eserlerin nasıl çözüleceği, staccato tekniğinin nasıl üstesinden gelinebileceği anlatılmıştır. Staccato tekniğinin daha kısa sürede çözüme kavuşturulması amaç edinilmiştir. Parmakların yerlerini öğrettiğimiz kadar belleğimize de çalışmaların kaydedilmesi önemlidir. Gösterilen azmin ve sabrın sonucu olarak ortaya çıkan yapıt başarıyı daha da yukarı seviyelere çıkaracaktır

    Automatic Question Generation to Support Reading Comprehension of Learners - Content Selection, Neural Question Generation, and Educational Evaluation

    Get PDF
    Simply reading texts passively without actively engaging with their content is suboptimal for text comprehension since learners may miss crucial concepts or misunderstand essential ideas. In contrast, engaging learners actively by asking questions fosters text comprehension. However, educational resources frequently lack questions. Textbooks often contain only a few at the end of a chapter, and informal learning resources such as Wikipedia lack them entirely. Thus, in this thesis, we study to what extent questions about educational science texts can be automatically generated, tackling two research questions. The first question concerns selecting learning-relevant passages to guide the generation process. The second question investigates the generated questions' potential effects and applicability in reading comprehension scenarios. Our first contribution improves the understanding of neural question generation's quality in education. We find that the generators' high linguistic quality transfers to educational texts but that they require guidance by educational content selection. In consequence, we study multiple educational context and answer selection mechanisms. In our second contribution, we propose novel context selection approaches which target question-worthy sentences in texts. In contrast to previous works, our context selectors are guided by educational theory. The proposed methods perform competitive to related work while operating with educationally motivated decision criteria that are easier to understand for educational experts. The third contribution addresses answer selection methods to guide neural question generation with expected answers. Our experiments highlight the need for educational corpora for the task. Models trained on noneducational corpora do not transfer well to the educational domain. Given this discrepancy, we propose a novel corpus construction approach. It automatically derives educational answer selection corpora from textbooks. We verify the approach's usefulness by showing that neural models trained on the constructed corpora learn to detect learning-relevant concepts. In our last contribution, we use the insights from the previous experiments to design, implement, and evaluate an automatic question generator for educational use. We evaluate the proposed generator intrinsically with an expert annotation study and extrinsically with an empirical reading comprehension study. The two evaluation scenarios provide a nuanced view of the generated questions' strengths and weaknesses. Expert annotations attribute an educational value to roughly 60 % of the questions but also reveal various ways in which the questions still fall short of the quality experts desire. Furthermore, the reader-based evaluation indicates that the proposed educational question generator increases learning outcomes compared to a no-question control group. In summary, the results of the thesis improve the understanding of the content selection tasks in educational question generation and provide evidence that it can improve reading comprehension. As such, the proposed approaches are promising tools for authors and learners to promote active reading and thus foster text comprehension
