A performance comparison of microstripline circuits using thin and thick film techniques has been studied, in which a Microstrip rejection filter, in the X-band of microwaves, is used as test circuit. A thick film technique is capable of giving good adhesive films with comparable d.c. sheet resistivity, but other parameters such as open area (porosity), particle size, and edge definition are inferior to thin-film microstrip filters. Despite this drawback, the average value of transmission, transmission loss, reflection coefficient, resonant rejection frequency, and quality factor for thick-film filters indicate that screen printed Ag films are intermediate between thin-film1,2,9and etched-thick-film9microstrip filters in performance, making it a feasible method for microstrip circuits.

Framing through the concept of precarity, we share our arts-based research on the experiences of creating a collaborative performance-making project focused on connecting students from different education levels, to create a film-dance integrated performance to advocate for social justice issues in education. We, as instructors and researchers, embarked on an arts-based research journey creating sketches, poems, videos, and a dance performance to analyze and represent our research findings. Our performance from the performative inquiry shows our understanding of the collaboration project through the same art form we required our students to utilize: film and dance-integrated arts performance.

Academic research pertaining to the marketing of film industry has identified advertising, film-making, and star power as the important factors influencing a movie’s market performance. Prior research, however, has not investigated the joint influences of these factors. The current study has extended previous research by analyzing the investment decision of studios or investors. In order to analyze the optimal film investment decision in advertising, film-making, and stars power, this paper develops a goodwill model and system dynamic (SD) model, which allow us to disentangle the effects of advertising, film-making, and star power on film market performance. The results show that the film producer should increasingly lay emphasis on investing in advertising to absorb moviegoers’ attention. Then the film producer should focus on investing in film-making when film quality has a great impact on the movie's reputation and audience's viewing decision. Furthermore, the film producer should pay more attention to the higher cost-performance stars who have more reasonable remuneration, better acting skills, and bigger box-office guarantee. Moreover, the numerical analysis reveals that rational audience contribute more than fans to a movie's box-office and bankable stars contribute more than high-profile stars to a movie's returns. Through SD simulation analysis, the film series yields higher profits than new theme movies although the cost of investment is the same.

The interest for pure sulfide Cu(In,Ga)S2 chalcopyrite thin films is increasing again because their optical properties make them relevant candidates to be applied as top cell absorbers in tandem structures. Nonetheless, their use as so is still hindered by the level of single-junction cells performance achieved so far, which are far below those demonstrated by selenide absorbers. Amongst the reasons at the origin of the limited efficiency of Cu(In,Ga)S2-based solar devices, one can mention the poor tolerance of S-chalcopyrite to Cu deficiency. In fact, Cu-poor Cu(In,Ga)S2 films contain CuIn5S8 thiospinel secondary phase which is harmful for device performance. In the present work, we investigate Cu(In,Ga)S2 thin films grown by a modified three-stage process making use of graded indium and gallium fluxes during the first stage. The resulting absorbers are single phase and made of large grains extended throughout the entire film thickness. We propose that such a morphology is a proof of the recrystallization of the entire film during the synthesis. Devices prepared from those films and buffered with bath deposited CdS demonstrate outstanding efficiency of 16.0%. Replacing CdS by Zn(O,S) buffer layer leads to increased open circuit voltage and short circuit current; however, performance become limited by lowered fill factor.

Films have been held for a long-term tradition as a meaning-making practice in visual and audio play, in the hybridization of language, image and sound, as well as in interactive symphonization with the audience/viewers. Through the emerging theoretical lens of translanguaging, this article analyzes the translingual practices, performance, instances in a Chinese film entitled Love After Love (adapted from Eileen Chang’s short story and directed by the Hong Kong Director Anne Hui), in which a Portuguese sonnet lyrical poem (Rimas) is delicately crafted in the film and projected in the trailer. Through this analysis, we aim to examine how translanguaging aesthetics transcend language boundaries, transforming from the seeming untranslatability to communicative meaning-making practice. The film presents a situated and embodied poem recital scene that encompasses untranslatable moments of imagination, thus transcending the Mandarin-English-Portuguese divide. The encounter and intertwining of heterogeneous languages and registers create a transformative space replete with tensions between reality and imagination, between lucidity and ambiguity, between resistance and compliance, interrogating the underlying discourses beyond languages and rendering the untranslatability meaningful. This translanguaging-informed film review thus offers an insightful autopsy of the literary aesthetics of the novel by Eileen Chang.

Abstract This personal essay articulates filmmaker Lynne Sachs's experiences working with experimental filmmaker Barbara Hammer. Sachs conveys the journey of her relationship with Hammer when they were both artists living in San Francisco in the late 1980s and 1990s and then later in New York City. Sachs initially discusses her experiences making Carolee, Barbara and Gunvor (US, 2018), which includes Hammer, the conceptual and performance artist Carolee Schneemann, and the experimental filmmaker Gunvor Nelson. She then discusses her 2019 film, A Month of Single Frames, which uses material from Hammer's 1998 artist residency in a Cape Cod shack without running water or electricity. While there, she shot film, recorded sounds, and kept a journal. In 2018, Hammer began her process of dying by revisiting her personal archive. She gave all of her images, sounds, and writing from the residency to Sachs and invited her to make a film with the material. Through her own filmmaking, Sachs explores Hammer's experience of solitude. She places text on the screen as a way to be in dialogue with both Hammer and her audience. This essay provides context for the intentions and challenges that grew out of both of these film collaborations.

Pełny tekst źródłaStreszczenie:
This thesis investigates how Victor Turners concept of cultural performance can be used to explore and analyse the experience of film. Drawing on performance theory, hermeneutics, phenomenology and Bakhtins dialogism, Sections One and Two develop this investigation through a theoretic discussion which relates and yet distinguishes between three levels of performance in film: filmmaking performance, performances as text and cultural performances. The theory is grounded within four films which were researched for this thesis: Once Were Warriors (Lee Tamahori, 1994), Rats in the Ranks (Bob Connolly and Robin Anderson,1996), beDevil (Tracey Moffatt, 1993) and Link-Up Diary (David MacDougall, 1987). Section Three undertakes the close analyses of the latter two films. These analyses address specific cultural performances that are performed across cultures and which are concerned particularly with Australian societys relationship with indigenous Australians.
¶
Section One locates Turners concept of cultural performance within his wider theory of social drama and introduces the three-tiered mode of analysis which is developed throughout this thesis. His concept of liminality is also investigated in order to consider specific relationships between performances which take place in film and theatre. Performances which take place in film are located in this Section within the theatrical understanding of performance as for an audience. I describe this relationship between performances in film and theatre through Kristevas interpretation of Bakhtins concept of heteroglossia as intertextuality, especially through her distinction of a transformative intertextuality. Three specific concepts from theatre and performance theory are interrogated for their relevance to film theory:
1. Brechts theory of gest,
2. direct address to the audience in relation to the gaze in film and
3. Rebecca Schneiders conceptualisation of the performance artist.
¶
Using these three tropes of performance, Section Two develops a theory of performance in film. Besides Turners concept of cultural performance, this theory draws on aspects of several other substantial bodies of work. These works include Richard Schechners performance theory, Michael Taussigs understanding of mimesis, Vivian Sobchacks phenomenology of film, Paul Ricoeurs theory of text as meaningful action, Gadamers concept of meaningful play, Bakhtins conceptualisation of a dialogic text and Catherine Bells theory of ritualised behaviour. The two analyses in Section Three do not rigidly follow the three-tiered process of analysis which is developed in the previous two Sections. They rather focus on the films as sites for particular cultural performances which are specific for each film and which need for their description, different aspects of the theory that is offered through this thesis. These analyses especially draw on my interpretation of David MacDougalls transcultural cinema and Jodi Brooks conceptualisation of a gestural practice in film, which she positions both in terms of Brechts theatrical concept of gest and Walter Benjamins concept of the shock of modernity.
¶
The film analyses are of one fiction film, beDevil, and one non-fiction film, Link-Up Diary. Both films use audiovisual images of Aboriginal Australians as content. According the terms of this thesis, these people must also be considered as filmmakers. Although this role may constitute varying degrees of authority and power, a film analysis which considers the filmmaking roles of people whose images are present in the filmic text also allows a particular consideration of the social relationships which exist between people who film and people who are filmed. My focus on the cultural performances of these two films allowed an even closer description of this relationship for two reasons. Firstly, both Moffatt and MacDougall respectively present their own images in the films. Secondly, my analyses of these films as cultural performance draw out and describe the different ways in which the two films address the same social drama: the relationship between indigenous and non-indigenous Australians. My analyses expose how a description of these differences in address can extend beyond the distinction between one film as fiction and the other as non-fiction towards a description of the different ways in which people relate to each other, at both the individual level and at the level of society, through the production and reception of a particular film. While locating these films as cultural performances within in particular sets of social relationships, my consideration of film in this thesis in terms of theatrical performance also enables a description of the experience of film which draws on the social experience of live theatre. The theory developed in this thesis and its application in the analyses of these two films suggest further areas of research which might look more closely at whether or not, or how much people draw from the social practices of live theatre as they live their lives with film a signifying practice which has existed just over one hundred years.

Pełny tekst źródłaStreszczenie:
It is now well-known that The King and I has little claim to truth. Recent research has exposed the inaccuracy of the “biographical” works on which the musical is based: Anna Leonowens invented many things about her personal background and experiences. Much of her life, then, is a contrived fantasy. Yet her life of fantasy has been resurrected in countless adaptations, including the 1951 Rodgers and Hammerstein musical and its 2015 revival production, that ceaselessly draw audiences. The fascination of American audiences with Anna’s tale lies their belief in the timeless American ideals that her fantasy employs: those of freedom and equality, which undergird such myths as American exceptionalism and American multiculturalism. The appeal of this cultural fantasy is illuminated by examining the history of the Cold War era in which The King and I was created, as well as the politics of President Trump that define recent years and influence the creation and reception of the revival show (and its 2016-2018 national tour). America today is occupied by the same conflicting desires for integration/internationalism and isolationism of bygone times; today, the idea of a superior America is still upheld by a fear of the Other. Examining how the visual elements, songs, and performances of the original and revival musicals both reinforce and undermine the fantasy of cultural superiority will reveal how Americans continue to fall under the spell of fantasy, and how a connection to the past sheds light on what it means to be an American today.

The research project 'This is my Face: Audio-visual practice as collaborative sense-making among men living with HIV in Chile' is an interdisciplinary project that explores 'collaborative mise en-scène' as a method to further understand the sense-making processes around the biographical disruption caused by HIV. It combines Anthropology and Arts methods as part of the PhD in Anthropology, Media and Performance, a practice-based program that fosters interdisciplinary approaches to the production of original knowledge, based on self-reflexive and critical research practices (The University of Manchester, 2018). Relying on the specific competences of photography and film and the co-creation of an ethnographic context based in hermeneutic reflexivity, the collaborators on the project created and explored representations of critical life events, in order to make sense of the disruption HIV brought to their lives. The collaborators were highly stigmatised individuals living with HIV, which hindered their possibilities for sharing narratives and for reflection, and as such, made it more difficult for them to come to terms with a diagnosis they described as a 'fracture' in their lives. This project analyses the creative process of 'collaborative mise-en-scène' as a way to provide further opportunities for reflexivity and sense making, a method that departs from their everyday face-to-face encounters as means of understanding what they are going through. Representations of life events emerged from our practice, as well as evocations, which provided a means by which to understand their experiences with HIV, and opened up ways to resignify their past experiences and projections of the future. Photography and film offered their specific expressive competences to the project, but also gave the possibility of making visible the collaborators' experiences in order to promote a dialogue with others, moving beyond our creative encounters. Therefore, their evocations became 'statements' of what it means to live with HIV in Chile, and at the same time, by taking part in its creation, it provided access to the particularities of the sense-making process in which those images were embedded. This collaborative creative process opened up ways to highlight the relevance for sense-making in face-to-face encounters, demonstrating that hermeneutic reflexivity as a practice-based form of mutual questioning can promote a critical engagement with life trajectories and with others beyond our practice.

A key element that enables a firm to achieve better performance, the strategy-making process is of great interest to both researchers and practitioners. However, the bulk of past research has focused on the process alone and has reached few consistent conclusions. Recently, researchers have started to investigate the impact of crucial contingencies on strategy-:making. It appears this contingency approach is more fruitful in deepening and broadening our understanding of this critical area.
To continue the research in this direction, this study inquired into the linkage between the environment and the strategy-making process. A theoretical framework was developed after surveying the germane literature to guide the empirical analysis. Following this model, comprehensiveness, or the exhaustiveness and the inclusiveness in strategy-making, was selected as the key process attribute for this study. It was hypothesized that environmental complexity, or the number and heterogeneity of factors in the environment, and dynamism, or the degree of change, would impact the perceived uncertainty of the strategy maker, and further comprehensiveness in strategy-making. In addition, it was posited that the match between strategy-making comprehens1veness and environmental attributes would lead to better firm performance.
The computer industry served as the setting for this study. Questionnaires were mailed to top executives of randomly selected computer firms to obtain data on environmental attributes and strategy-making comprehensiveness. Secondary sources were used to acquire financial performance data and other background information.
Analysis results suggest that the proposed model is useful in understanding the environment and strategy-making interaction. Both environmental complexity and dynamism were found to influence strategy-making comprehensiveness. Moreover, the adaptation of strategy-making comprehensiveness to environmental attributes was found to lead to better firm performance. Findings from this study hold promise for effective strategic management and. contribute insight into the strategy-environment linkage.Ph. D.

Using a large sample of about 1,900 M&A deals from 1993 to 2005, and data on more than 3,100 CEOs, I explore merger and acquisition activities from a psychological perspective, and provide another explanation for M&A motives and associated firm stock performance. Specifically, I empirically test if highly narcissistic CEOs are more likely to conduct mergers or acquisitions than lowly narcissistic CEOs. I also examine the impact of high level of CEO narcissism on the market reaction to firm M&A announcements, and also long run post-M&A stock returns. In addition, I empirically investigate the impact of the parallel CEO narcissistic tendency of target firm on acquiring firm M&A performance. Three proxies for CEO narcissism are used in this study: Holder67, a CEO option exercise-based measure, CEO media portrayal, and a third new measure based on the formal content analysis of actual CEO speech. I find empirical evidence that CEOs with high level of narcissism are more likely to conduct mergers and acquisitions than other CEOs. My results also suggest that a high level of acquiring firm CEO narcissism has a significantly negative impact on acquiring firm short run M&A performance. Post-acquisition, I find that deals conducted by highly narcissistic CEOs significantly underperform those by lowly narcissistic CEOs. Moreover, my results show that a high level of target firm CEO narcissism similarly negatively affects acquiring firm short run M&A performance. In an additional analysis, I find that the positive link between CEO narcissism and the likelihood of a CEO conducting an M&A deal is stronger and the impact of CEO narcissism on firm M&A performance is more negative in large firms than that in smaller firms. My results also show that the negative impact of CEO narcissism on firm short run M&A performance is strongest when both acquiring firm and target firm CEO narcissism coexist concurrently. However, I find that the level of CEO narcissism is negatively associated with the quality of corporate governance, and the positive link between CEO narcissism and the likelihood of a CEO conducting an M&A deal is weaker in firms with good corporate governance than that in firms with poorer corporate governance, which may suggest that effective corporate governance mechanisms might play positive roles in curbing CEO narcissistic tendencies and in helping to ameliorate, to some extent, the adverse impact of high level of CEO narcissism on firm M&A decision making.

Pełny tekst źródłaStreszczenie:
Maintenance management is seen as a “necessary evil”, rather than a profit contributing
resource that could intensify competitive advantage for the organisation. With the world facing
the fourth industrial revolution, a radical increase in the reshaping of companies and
competition within asset intensive industries is being observed. Organisations in these
industries are being forced to rethink traditional ways of working and gearing the workforce
with higher and more diversified competency profiles. This suggests that the traditional way
of executing maintenance management, being predominantly reactive with the lack of data
driven decision making, is certainly inadequate for a sustainable competitive advantage. An
improved way of managing maintenance should be through developing and applying dynamic
capabilities within the maintenance domain of the organisation.
This research draws on theories of dynamic capabilities (DC), decision making performance
(DMP), business process performance (BPP) and firm performance (Fper), in the context of
data driven decision making in organisations heavily reliant on good maintenance
management practices. The aim of this study was to explore and understand the relationships
between these constructs, for insight into further improvement and development of a
competitive advantage.
The findings presented a statistically significant relationship between DC and Fper, DC and
BPP, DC and DMP, but most importantly, a multiple full indirect mediation role was observed,
which provides insights for both business and for further studies in academia.Mini Dissertation (MBA)--University of Pretoria, 2020.

Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2016. https://ro.ecu.edu.au/theses/1928.
Pełny tekst źródłaStreszczenie:
Today, many Malaysian SMEs are facing problems that hinder the full implementation of computerised accounting information systems (CAIS). These problems are related to human resources incapable of using the systems and organisation’s inability to adopt the technology and align it with the companies’ strategic policy.
The purpose of this study is to empirically test the impact of CAIS on information quality, focusing on the transparency aspects of corporate governance and strategic decision making (SDM). Accounting information systems (AIS) with a ‘good fit’ and ‘highly praised’ corporate governance (CG) practices have been shown to lead to good firm performance. While the literature has examined the effects of AIS fit on firm performance, few studies have looked at the link between CAIS, information quality and firm performance. Further, while the impact of strategic decision making and CG on firm performance has been widely studied, the role of AIS in this relationship is less clear. Since AIS forms the backbone of a firm’s business information infrastructure, both strategic decision-making process and corporate governance, particularly the transparency dimension, rely on information derived from the system.
Using a resource-based view (RBV) framework, hypothesised relationships among variables of interest were examined based on data collected from 336 small and medium size enterprises (SMEs) in Malaysia. Results from partial least square (PLS) analysis suggest that effects of AIS on firm performance were partially mediated by information quality, while a full moderation effect was found for other variables on firm performance.
The results thus demonstrate the importance of information quality, SDM and AIS to a greater height, prompting SMEs to revisit their policies on AIS, staff training and largely transparency to better improve firm performance. Outcomes of this study contribute to the body of knowledge on AIS, information quality and SMEs, while helping to trigger interest among SMEs on the importance of having reliable accounting software to produce quality reports.

Pełny tekst źródłaStreszczenie:
Researched in this thesis is the financial impact of employee involvement and performance- related pay systems in UK manufacturing and retail settings. The test questions are introduced in Chapter 1 along with some micro- and macro-level factors which may make it efficient to involve employees in decision-making and to pay basis performance. Chapter 2 discusses theoretical issues associated with involving employees in decision-making and using group-based incentives. There is support from both the theoretical and empirical literature that employee involvement and performance-related pay are more efficient when used in combination. Chapter 3 evaluates methodological issues associated with the examination of these questions, including methods used to attribute for unobserved heterogeneity and endogeneity in the econometric analysis. In Chapter 4 case study evidence is gathered from the retail sector on the adoption of, and associated performance trends with the use of, an All Employee Stock Option Programme (AESOP) and extensive employee communication programmes. Sources at the company indicate that the use of these practices are thought to result in greater employee effort and efficient information sharing. Performance trends, since the adoption of these programmes, indicate improved performance within the company and relative to competitors which do not offer an AESOP. Econometric analysis is used in Chapter 5 to examine the financial impact of individual, team and group pay systems in UK manufacturing establishments where there is work task 'interdependence'. Evidence is found that in team production settings group payments systems are the most efficient pay system. Chapter 6 examines the impact of two forms of employee involvement, decentralized decision-making and two-way information sharing, on establishment performance. These practices are examined both including and excluding incentives. A statistically significant impact on establishment performance is found when performance-based incentives are included: this result disappears when the incentives are excluded. A second econometric analysis is conducted in Chapter 6, evaluating the independent and interactive effects of decentralized decision-making and group incentives in team production settings. Evidence is found that sub-optimal performance results in establishments which use only decentralized decision-making or only group incentives. Establishments that use the practices in combination have the best performance. Chapter 7 is the summary and conclusion.

He, Wei. "Essays of Strategic Alliance Portfolio Configuration— Its Performance Properties, Strategic Antecedents and Consequential Effects on Multinational Firms’ Continuing Foreign Expansion". FIU Digital Commons, 2012. http://digitalcommons.fiu.edu/etd/697.
Pełny tekst źródłaStreszczenie:
This dissertation focused on an increasingly prevalent phenomenon in today’s global business environment—strategic alliance portfolio. Building on resource-based view, resource dependency theory and real options theory, this dissertation adopted a multi-dimensional perspective to examine the performance implications, strategic antecedents of alliance portfolio configuration, and its strategic effects on firms’ decision-making on their continuing foreign expansion.
The dissertation consisted of three interrelated essays, each of which dealt with a specific research question. In the first essay I applied a two-dimensional construct that embraces both alliance relations’ and alliance partners’ attributes to illustrate alliance portfolio configuration. Based on this framework, a longitudinal study was conducted attempting to explore the performance properties of alliance portfolio configuration. The results revealed that alliance diversity and partner diversity have different relative contributions to firms’ economic performance. The relationship between alliance portfolio configuration and firm performance was shaped by degree of multinationality in a curvilinear pattern. The second essay attempted to identify the firm level driving forces of alliance portfolio configuration and how these forces interacting with firms’ internationalization influence firms’ strategic choices on alliance portfolio configuration. The empirical results indicated that past alliance experience, slack resource and firms’ brand images are three critical determinants shaping alliance portfolios, but those shaping relationships are conditioned by firms’ multinationality. The third essay primarily employed real options theory to build a conceptual framework, revealing how country-, alliance portfolio-, firm-, and industry level factors and their interactions influence firms’ strategic decision-making on post-entry continuing expansion in foreign markets. The two empirical studies were resided in global hospitality and travel industries and use panel data to test the relevant theoretical models.
Overall, the dissertation advanced and enriched the theoretical domain of alliance portfolio. It particularly shed valuable insights on three fundamental questions in the domain of alliance portfolio research, namely “if and how alliance portfolios contribute to firms’ economic performance”; “what determines the appearance of alliance portfolios; and “how alliance portfolios affect firms’ strategic decision-making”. This dissertation also extended the international business and strategic management research on service multinationals’ foreign expansion and performance.

The opening decades of the twentieth century witnessed a profound transformation in the history of modern sound media, with workers in US film, radio, and record industries developing pioneering production methods and performance styles tailored to emerging technologies of electric sound reproduction that directly shaped dominant forms and experiences of modern sound culture. Focusing on broadcasting’s initial expansion period during the 1920s, Making Radio explores the forms of creative labor pursued for the medium before the better-known network era of the 1930s and 1940s, assessing their role in shaping radio’s own identity and identifying affinities with parallel practices pursued for conversion-era film and phonography. Tracing programming forms adopted by early radio writers and programmers, production techniques developed by studio engineers, and performance styles cultivated by on-air talent, it shows how radio workers negotiated a series of broader industrial and cultural pressures to establish best practices for their medium. In the process, it argues, these sound workers shaped not only the future of broadcasting, but also contributed to much broader shifts in popular forms of music, drama, and public oratory, ushering in a new era of electric sound entertainment.

This chapter examines how jazz fans, especially the most active concertgoers (the regulars), respond to a musical performance. It first considers how fans become part of jazz communities and how they contribute to the New York City jazz scene. It then shows how nonperforming musicians fill the performance space, suggesting that these offstage participants, who are also “performing” jazz, constitute the unseen scene, the silent and not-so-silent majority that forms an integral part of communal music-making. It also explains what happens when fans are in the house: how their musical tastes develop, how they view performers and performances, and how their private and public listening practices inform their understandings of and appreciation for jazz and jazz performances. The chapter concludes that when jazz audiences with “big ears” attend to and interact with live music and musicians, it creates a sympathetic environment where jazz can come alive.

When midcentury Hollywood found itself struggling to compete within an expanding entertainment media landscape, certain producers and studios saw an opportunity in making films that showcased performances by rock ’n’ roll stars. Such stars eventually found cinema to be a useful space to extend their creative practices, and the motion picture and recording industries increasingly saw cinematic rock stardom as a profitable means to connect multiple media properties. This book examines how casting rock stars for film provided a tool for bridging new relationships across media industries and practices. Rock Star/Movie Star offers a new perspective on the role of stardom within the convergence of media industries. While hardly the first popular music culture to see its stars making the transition to screen, the timing of rock’s emergence and its staying power within popular culture proved fortuitous for a motion picture business searching for its place in the face of continuous technological and cultural change. At the same time, a post-star-system film industry provided a welcoming context for rock stars who have valued authenticity, creative autonomy, and personal expression. Examining stars from Elvis Presley to Madonna, this book uses illuminating archival resources to demonstrate how rock stars have often proven themselves to be prominent film workers exploring this terrain of platforms old and new—ideal media laborers whose power lies in the fact that they are rarely recognized as such.

This introductory chapter first sets out the book's purpose, which is to offer fresh histories and theoretical inquiries that will resonate not only for scholars working in the field of dance, but also for scholars working on literature, film, visual culture, theater, and performance. It then sketches the intellectual and artistic trends over the last thirty years that have shaped the scholarship featured in New German Dance Studies. It follows the broadly chronological organization of the volume as a whole: opening essays on theater dance before 1900; then research clusters on Weimar dance, dance in the German Democratic Republic, and conceptual dance; and a closing reflection on the circulation of dance in an era of globalization. Throughout it emphasizes the complex interplay between dance-making and dance writing, as well as interrelations between dance practice and research and artistic and intellectual trends in German culture at large.

Well before the success of Loretta Lynn and Dolly Parton, female artists were integral to the commercial expansion and aural reception of country music. Women in early country music took on and redefined the theatrical and musical roles of the hillbilly maiden, the unruly Okie, the singing cowgirl, and the honky-tonk angel in live performance, on radio, in film, and in the recording studio. This book accounts for the vibrant presence of female country artists through an interdisciplinary focus on performance and vocal expression in relation to the cultural currents of the 1930s and 1950s. Across a variety of media, women’s country music engendered new ways of making sense of public and private spaces (such as the home, the dance hall, and the honky-tonk) that were integral to the real and imagined lives of working-class women striving for upward social mobility and/or resisting the rigidity of middle-class codes of behavior. Connecting the female singing voice to the theatrics of the popular stage and to the musical practices of specific country styles, this study shows how women in country music wielded a range of performative devices in order to work within and against social and commercial expectations.

Bob Dylan has constantly reinvented the persona known as “Bob Dylan,” renewing the performance possibilities inherent in his songs, from acoustic folk, to electric rock and a late, hybrid style which even hints at so-called world music and Latin American tones. Then in 2016, his achievements outside of performance – as a songwriter – were acknowledged when he was awarded the Nobel Literature Prize. Dylan has never ceased to broaden the range of his creative identity, taking in painting, film, acting and prose writing, as well as advertising and even own-brand commercial production. The book highlights how Dylan has brought his persona(e) to different art forms and cultural arenas, and how they in turn have also created these personae. This volume consists of multidisciplinary essays written by cultural historians, musicologists, literary academics and film experts, including contributions by critics Christopher Ricks and Nina Goss. Together, the essays reveal Dylan’s continuing artistic development and self-fashioning, as well as the making of a certain legitimized Dylan through critical and public recognition in the new millennium. This volume seeks to reflect the range of Bob Dylan’s multiple activities, the ‘late style’ of his creativity and his personae in all their later variety, from the Time Out of Mind album (1997) up to the release in March 2020 of ‘Murder Most Foul’. Bob Dylan (born 1941) is perhaps best-known as a singer and songwriter whose major impact occurred several decades ago. His achievements as a songwriter and master of language were – provocatively? – acknowledged when he was awarded the 2016 Nobel Literature Prize. However, Dylan has never ceased to broaden the range of his creative identity, especially through intermediality, taking in painting, film, acting, radio-presenting and prose writing, as well as advertising and even own-brand commercial production, either reinforcing or calling into question his perceived authenticity. The book highlights how Dylan has brought his persona(e) to different art forms and cultural arenas, and how they in turn have also created these personae. Chronicles, Volume One, his autobiography, charts his beginnings as a folk singer and the later recording of the Oh Mercy album. In terms of his identity as a visual artist, while Dylan’s Revisionist Art exhibition focused on his reworkings of magazine covers, the Brazil Series paintings show him extending his visual creativity to cultural spaces beyond the United States. Dylan has constantly reinvented the persona known as ‘Bob Dylan’.

This introductory chapter provides an overview of the book's main themes. This book explores the disavowed claims of the past on the present through a group of cultural productions—literature, drama, and film—focused on racialized subject-formations and cultural formations. Investigating the intersection of categories of social difference, nation making, and buried social memory, it uncovers a host of hidden dialogues for the purpose of dismantling the legacy effects of historical racial subjugation and inequality. The book brings psychoanalytic paradigms of mourning and melancholia and discussions of race and performance by W. E. B. Du Bois, Frantz Fanon, Julian Carter, Diana Taylor, and Kimberly Benton into conversation with literary work on post-Emancipation America's everyday life and ritual practice to challenge scholarship that calls for the clinical separation of ethnic studies and psychoanalysis as well as the divorce of psychoanalysis and socioeconomic history, and presumes that this disengagement is central to American nationhood's continued relationship with unresolved racial grievances. This study develops a theory of “cultural melancholy” that uncovers the ideological and psychical claims of the history of slavery and ongoing racial subjugation on contemporary racialized subject-formations and dominant American culture.

Inspired by the celebrated pianist-bandleaders Eddy Duchin and Carmen Cavallaro and the cinematic technique of José Iturbi in Hollywood films, pianist-entertainer Liberace (1919–1987) developed a distinctive and highly successful aesthetic and performance style that prioritized visual spectacle and emphasized the tactile elements of his playing. As evident in his first Soundies from 1943, then his nationally syndicated television show in the 1950s, Liberace highlighted the physicality and materiality of his music-making, an approach that later evolved into the signature props and flashy costumes of his live stage shows. The new medium of television enabled Liberace to integrate the traditions of Romantic pianism with new genres of popular music in a highly embodied manner that appealed to his fans as much as it bothered his critics invested in music’s physical and material transcendence.

AbstractIn 1997, independent Swiss filmmaker and anthropologist Jaqeuline Veuve (1930–2013) released her documentary Journal de Rivesaltes, 1941–1942 based on the journal kept by Friedel Bohny-Reiter (1912–2001) while working as a nurse for the Swiss Red Cross/Aid to Children at the Rivesaltes internment camp in southwest France. This chapter will show how Veuve’s film brought public attention to hitherto unknown women humanitarians and contributed to shaping a new understanding of Switzerland’s role in the Second World War. It will also examine the film as a performance of both the trauma of others in the past and that of the public facing this history in the late 1990s, thus constituting an important source for the history of emotions.

This chapter examines Almodóvar’s film Los amantes pasajeros/I’m So Excited! against the backdrop of Spain’s economic crisis. Describing the shift of director Pedro Almodóvar from melodrama to drawing room farce made evident in this film, the chapter highlights its theatricality; in so doing, it argues that the Los amantes pasajeros owes much to broad traditions of theatre acting that range from vaudeville, to mime to classic Shakespearian. The language of theatrical acting that the film employs, to that end, incorporates gestures and dramatic histrionics in order to make a clear indictment of the current state of Spain in crisis. By making clear the links between the politics of acting and acting out politics, the chapter’s account of performance further demonstrates just how nuanced the landscape of Spanish acting can be.

This chapter demonstrates how racial segregation by film genre shapes directing paths in Hollywood. Black directors are over represented in the music genre, which is arguably the most performance oriented genre and also records the smallest average production budgets, figuratively placing them in the genre ghetto of the most impoverished genre. The music genre is also a literal genre with many Black-directed music genre films having themes of urban poverty and ghetto life. In contrast, Black directors are most underrepresented in the science fiction genre, which is thought to be intellectual-minded, and as directors of tent pole blockbuster franchise movies that are Hollywood studios’ core movie products. Black directors are therefore least represented in the most lucrative and commercial genre in American cinema. Racial segregation in genres lead to career disparities, as directing big franchise movies enables whites to attain commercial success that alludes racial minorities who less often direct tent pole movies.

This essay discusses how feminist filmmaking techniques embody the explicit construction of identity through a shared and collaborative approach to subject participation and performance in relation to ideas around ‘voice’. It highlights the use of ‘hybrid’ practices and border-crossing in film and art processes. The author shows how strategies of participation and performance allow for non-binary complexities and voice-making to emerge.

By 1941, Cary Grant had his pick of films. Almost everything was offered to him and everyone wanted to work with him. Wary of being typecast, he resisted making more screwball comedies. Instead, he made the gentle “weepie” Penny Serenade (1941) with George Stevens directing and Irene Dunne co-starring. His performance, including a tearful moment when he must plead with a judge to maintain custody of an adopted child, brought his first nomination for an Academy Award. He made an even more dramatic departure from his established image playing the wayward, possibly murderous Johnny Aysgarth in Alfred Hitchcock’s Suspicion (1941). The making of this film was rocky, not least because of on-the-set friction between Grant and co-star Joan Fontaine, but Grant’s relationship with Hitchcock was strong both personally and professionally. His relationship with director Frank Capra, with whom he made Arsenic and Old Lace (1944), was not as strong. Grant hated his own manic performance in this slapstick comedy. Although the film was a big success at the time and still has many admirers, he always cited it as the least favorite of his films.

In 1937, Cary Grant’s career as a freelance star began with three screwball comedies that established him as the master of this genre. Topper (1937), made by the independent producer Hal Roach, initiated this sharp upturn in his career. This stylish screwball comedy brought out a new playful, wry, ironic dimension in Grant’s performance style. Improvisation on the set was key to his new screen persona, and he was given even greater reign to improvise in his first Columbia film, Leo McCarey’s The Awful Truth (1937). Legend has it that he was uncomfortable working with McCarey, but McCarey helped him to mould the Cary Grant star persona, unique for combining debonair and slapstick qualities. He signed a contract with Columbia Pictures that gave him the power to choose which films he made, and control over both his publicity and his wardrobe, but it was a non-exclusive contract, allowing him to make his next film at RKO Pictures. In Bringing Up Baby (1938), director Howard Hawks encouraged a frenzied edge to his performance. This is perfectly exemplified in the famous scene in which Grant leaps in the air, shouting “I just went gay all of the sudden”—a line he improvised on the set and one that demonstrates the liberated, unconventional mores of screwball comedy. Bringing Up Baby had a mixed reception on first release in 1938, but in later years, through repeated revivals and screenings on television, it became one of his best known and most admired films.

In this chapter, moving image artist Isabel Rocamora reflects on the thematic, aesthetic and philosophical concerns that drive her intermedial art practice. The essay traces the ways in which core elements of her performance work – gesture, place, temporality and presence – in turn inform and are transformed by her film and video installations. A discussion of the ethical dilemmas that motivate Body of War (2010) and Faith (2015) – namely, military violence and ethnic segregation – opens up problems of identity and alterity as well as questions of form, structure and register. To address these, Rocamora places the illuminating philosophies of Martin Heidegger and Emmanuel Levinas into dialogue with her own directorial approach to casting, location, performance, cinematography, sound design and exhibition architecture. The aim of her moving images, she explains, is to draw out the personal from the collective in mise en scènes that dislodge performative action to expose ontological presence. The creative means, the essay concludes, emerge from the productive strife between the media.

A segment of permeable wall is installed near a row of cylindrical film holes, parallel to the flow and inclined at 35 degrees. Coolant is forced through both the permeable wall and the film holes resulting in a downstream film composed of both transpired and discretely injected coolant. The permeable wall extends 1.5 cylindrical hole diameters in the flow direction. The effects on the aerodynamic performance and cooling downstream of the row of cylindrical holes in the presence of transpiration is studied numerically with a procedure validated by hot-wire anemometer and temperature sensitive paint measurements. The hydrodynamic boundary layer in the presence of film and adiabatic film cooling effectiveness downstream of single and coupled film sources are compared with numerical predictions. The performance of the coolant film is predicted in order to understand the sensitivity of cooling and aerodynamic losses on the relative positioning of the two sources at each blowing ratio. The results indicate that a coupling of the two sources allows a more efficient use of coolant by generating a more uniform initial film. With careful optimization the discrete holes can be placed farther apart laterally and operate at a lower blowing ratio with a transpiration segment making the large deficits in cooling effectiveness mid-pitch less severe, overall minimizing coolant usage. Comparisons of linear superposition predictions of the two independent sources with the corresponding coupled scenario indicate the two films positively influence one another and surpass additive predictions of cooling. All relative placements have an overall beneficial effect on the cooling seen by the protected wall. Some cases show an increase in area-averaged film cooling effectiveness of 300% along with a 50% increase in aerodynamic loss coefficient by injecting an additional 10% coolant. In this study the downstream transpiration placement is found to perform best of the three geometries tested while considering cooling, aerodynamic losses, local uniformity and manufacturing feasibility. With further study and optimization this technique can potentially provide more effective thermal protection at a lower cost of aerodynamic losses and spent coolant.

U.S. Department of Energy (DOE) has recently sponsored research programs to develop megawatt scale supercritical CO2 (sCO2) turbine for use in concentrated solar power (CSP) and fossil based applications. To achieve the CSP goal of power at $0.06/kW-hr LCOE and energy conversion efficiency > 50%, the sCO2 turbine relies critically on extremely low leakage film riding seals like dry gas seal (DGS). Although DGS technology has been used in other applications before. making it successful for stringent conditions of an sCO2 turbo-expander is challenging. This paper presents results from a multi-scale coupled physics model that predicts the performance of DGS under a typical sCO2 turbine mission cycle and addresses some of the risks specific to operation in sCO2. Real gas equations of state are incorporated in the models to capture large discontinuities in fluid properties close to the critical point. A novel experimental setup is developed to observe and characterize transition of CO2 through liquid-vapor and supercritical phases. Coupled fluid-structure-thermal interaction model investigates the effect of aerodynamic and thermal perturbations on the structural and rotordynamic instabilities. Dynamic instabilities arising from sonic transition in thin sCO2 film of DGS pose additional challenges while the large surface roughness changes due to sCO2 corrosion warrant further design considerations. Effectiveness of features like spiral grooves in converting fluid momentum into pressure rise in the thin film and also in achieving local flow reversals is investigated. Effect of various design features on the optimal performance is quantified and insights for a successful DGS operation in a sCO2 turbomachine are provided.

Abstract In a cold spray technique (CS), which used for making dense and thick metallic coatings, the fine solid metallic particles are impinged and deposited on a substrate at subsonic or supersonic velocity. The property and performance of a CS metallic coating significantly depends on the bonding state of particle-substrate and particle-particle interfaces. Therefore, the deposition mechanism of the CS particles has become one of the most important research targets. However, it is difficult to experimentally evaluate the deposition mechanism due to numerous impingements of very fine particles with various size and shape. In this study, in order to evaluate the deposition mechanism, a CS emulated environment was created by a single particle shot system (SPSS) in which spherical particle with 1 mm diameter is impinged on a substrate. The influence of substrate surface oxide film on deposition behavior of a spherical Al particle with 1 mm diameter was investigated. The thickness of surface oxide film on a substrate was controlled by heat treatment and estimated by X-ray photoelectron spectroscopy (XPS). Using the SPSS, Al particles were impinged on the substrates with different surface oxide film thicknesses. The critical velocity, which means the starting velocity for particle deposition, and the microstructure of deposited particle were evaluated. From the results, it was found that the surface oxide films on substrates play important roles on the deposition behavior of the Al particle.

Abstract A detailed analysis of film cooling performance on a double-walled effusion-cooled blade is essential for both the coolant consumption optimization and assessment of the film to offer the desired levels of the turbine blade protection. Yet there are hardly any film effectiveness studies on double-wall full-coverage film cooled turbine blades. This paper presents a detailed film cooling effectiveness study over the full surface of a double-walled effusion-cooled high-pressure turbine rotor blade using Pressure Sensitive Paint (PSP). PSP permitted a non-intrusive and conduction-errors-free means of obtaining clean and distinct local distribution of film effectiveness on the blade surface making it possible to extract valuable film cooling effectiveness performance data on the whole blade surface. Three large-scale circular pedestal double-wall blade designs with varying pedestal height, pedestal diameter and cooling hole diameter were tested in a high-speed stationary single-blade linear cascade running at engine-representative Mach and Reynolds numbers. All the blades were tested within a range of representative modern engine coolant mass flow, ṁc to mainstream, ṁg ratios; 1.6% < ṁc/ṁ∞ < 5.5%. High porosity blade exhibited a better flow distribution and was found to consistently perform the best.

Both thermal and intrinsic stresses that occur during thin-film processing and assembly processes dominate the final residual stress in thin film electronic devices. Since the residual stress causes the shift of electronic functions of dielectric and semiconductor materials, these shifts sometimes degrade their performance and reliability. Therefore, it is very important to measure and control the residual stress in thin-film-applied products. In this study, the changes of the electronic performance of MOS transistors by mechanical stress were measured by applying a four-point bending method. The stress sensitivity of the transconductance of NMOS transistors increased from about 1%/100-MPa to about 15%/100-MPa by decreasing the gate length of the transistors from 400 nm to 150 nm. One of the estimated important factors which dominated this increase was attributed to the interference of stress concentration fields occurred at the edges of gate-electrodes. The change of the residual stress in a transistor structure caused by deposition of thin films was analyzed by applying a finite element method (FEM). The estimated change was validated by experiment using originally developed stress sensing chips. The estimated change of the stress due to deposition of gate electrode tungsten film was about 25MPa. The measured average stress was about 20MPa and it agreed well with the estimated value. In addition, the change of the residual stress caused by the interference of the stress concentration fields between two gate-electrodes was validated by applying this stress sensing chip. The measured change of the stress caused by making fine slits by focused ion beam was about 70MPa and it agreed well with the estimated value of about 60MPa. It was confirmed, therefore, that both the thin film process-induced stress and the assembly-induced stress change the final residual stress in a transistor structure and the change can be evaluated by our stress-sensing chip quantitatively.

In modern gas turbines, film cooling technology is the most common and efficient way to provide thermal protection for hot parts. To improve film cooling effectiveness, different kinds of shaped holes have been designed, but most of them are complicated and difficult to machine. In this study, four cases of novel film cooling hole design, all based on cylindrical holes, are numerically studied. One is a single, two-stage cylindrical hole, whose downstreamhalf-length has a diameter D while the upstreamhalf-length has a diameter D/2. A second has a cylindrical primary hole with two smaller secondary holes located symmetrically about the centerline of the primary hole and downstream of the primary hole. The three holes of this second design are then combined to make a single shaped hole, constituting a third case, called the tri-circular shaped hole. The entry part of the third case is replaced by a cylindrical hole with a diameter of half the primary hole diameter, making a fourth case called the two-stage tri-circular shaped hole. Film cooling effectiveness and surrounding thermal and flow fields are numerically investigated for all four cases using various blowing ratios. It is shown from the simulation that the two-stage cylindrical hole cannot improve film cooling effectiveness. The primary hole with two secondary holes can enhance film cooling performance by creating anti-kidney vortex pairs, which will weaken jet lift-off, caused by the kidney vortex pairs, from the primary hole. The tri-circular shaped hole will provide better film cooling effectiveness near the hole area, and is not sensitive to blowing ratio. The two-stage structure for tri-circular shaped hole provides better film coverage because it changes the flow structure inside the channel and decreases jet penetration.

This article discusses the current status and achievements of R2R technology for large area nano-scaled optical devices developed at MSL/ITRI. Firstly, a single layer of nanostructure on polymer film is designed for anti-reflection purpose by finite difference time domain (FDTD) method in the visible light spectrum. The conical array with around 1 aspect ratio, like moth-eye shape and showing superior performance in the optical simulation, has been adapted for the R2R experiments. The development of R2R process includes roller machine design and fabrication, roller mold design and making, development of rolling imprint process, characterization of rolled devices. In this study, large area (200mm *200mm) Ni template was fabricated with DUV exposure, followed by dry etching and electroforming process, respectively. Then, the template was bonded on the roller mold with magnetic film to make nanostructure roller mold. With the delicate nanostructure roller mold, systematic experiments have been conducted on the home-made roller machine with various parameters, such as linear speed, dose rate, and material modifications. The duplicated nanostructure films show very good optical quality of anti-reflection (AR < 1%) and are in good agreement with the theoretical predictions. Besides, the duration of the roller mold has been highly promoted to hundreds of imprint in the UV embossing process.

Abstract Additive Manufacturing (AM) is a process for making complex parts that were once difficult to machine using traditional manufacturing processes such as forging, casting, and welding. As a new and promising processing technology, AM is being increasingly applied to the manufacturing of high temperature turbine parts. However, before the widespread application of AM can become feasible, the influence of such processes on the performance of turbine hot ends — especially during the film cooling flow heat transfer — requires further study. This paper focuses a large eddy simulation study done in order to understand the physical phenomena involved in the random roughness caused by the AM of fan-shaped film holes. This paper proposes a set of workflows to connect the AM, CFD simulation, Computed Tomography (CT) and reverse modeling, so that the effect of AM on the flow and heat transfer of film cooling can be studied. The results of this preliminary workflow reveal several observations. First, that the film cooling effectiveness (η) of AM fan-shaped holes decreases. The area averaged η of the ideal hole is 0.32, while the area averaged cooling effectiveness of the AM hole is 0.29. As such, the η of the AM fan-shaped hole has a significant bifurcation phenomenon. This is because the separation bubble in-tube moves forward, and blocks the flow channel, which bifrucates the flow in-tube. Second, a pressure gradient towards the trailing edge generated at a random rough surface near the leading edge squeezes the fluid. The combined effect of these two mechanisms causes the fluid to flow out of the air film pores mainly from the leading edge with a smaller lateral expansion.

Highly parallelized biochemical analysis is a significant step toward achieving high throughput processing of patient samples for diagnosis and treatment monitoring. The standard microtiter plate is used to carry out multiple reactions for high throughput screening. By incorporating polymer microfluidic devices at each well in the microtiter plate format, the capability of the format could be significantly enhanced for high throughput processing of large numbers of biochemical samples in a cost-effective manner. Low cost replication of the microtiter plates is done using micro molding techniques, so microfabrication technology for making large area mold inserts (LAMIs) containing microfluidic devices at each well of a microtiter plate format is needed. A large area mold insert (LAMI) in the footprint of the standard microtiter plate was fabricated using an SU-8 based UV-LIGA technique. Excellent lithography results, with vertical sidewalls, were obtained by utilizing flycutting to minimize SU-8 film thickness variation and a UV filter for attenuating high absorbance UV wavelengths. Overplating of nickel in the SU-8 polymeric molds was used to make high quality metallic mold inserts with vertical sidewalls. Micro molding of polycarbonate (PC) was done using hot embossing, resulting in good replication fidelity over the large surface area. Thermal fusion bonding of the molded PC chips yielded good sealing results and the developed polymer microfluidic platforms showed good fluidic uniformity.

The present paper investigates the effects of purge flow from a stator-rotor seal gap on the aerodynamic and thermal performance of a rotor blade cascade. Particular attention is paid to thermal results in the leading edge area that is typically difficult to protect. Experimental tests have been performed on a seven-blade cascade of a high-pressure rotor stage of a real gas turbine at low Mach number (Ma2is = 0.3). To simulate the rotational effect in a linear cascade environment, a number of inclined fins have been installed inside the stator-rotor gap, making the coolant flow to exit with the right tangential velocity component. Tests have been carried out at different blowing conditions, with mass flow rate ratios up to 2.0%. Aerodynamic effects of purge flow on secondary flow structures were surveyed by traversing a 5-hole miniaturized pressure probe in a plane 0.08cax downstream of the trailing edge. Film cooling effectiveness distributions on the end wall platform were obtained by using Thermochromic Liquid Crystals technique. Results allowed to investigate the effect of purge flow injection from the upstream gap on the secondary flows development and on the thermal protection capability. Purge flow injection of 1.0% reduced secondary flow losses and was found to effectively protect the front end wall region, up to about 0.5cax downstream of the leading edge. Increasing the purge flow up to 1.5%–2.0% provided a better thermal protection not only stream wise, but also in the region close to the leading edge because of the weakened washing activity of the horseshoe vortex.

This paper assesses whether the expansion of online job vacancies leads to a more efficient labor market. We provide compelling evidence that the increase in online job vacancy penetration in Colombia has had an enhancing effect on the labor market's efficiency by making it easier for firms to find workers to fill their job openings. An estimation of the Beveridge Curve (unemployment to vacancies relationship), a well-established theoretical development from search models, concludes that policies that increase online vacancy posting enhance efficiency. We implement a differences in differences design to take advantage of a regulation, which mandates that all authorized online vacancy providers report any online vacancy to the Public Employment Service in Colombia. We find that sub-segments of the labor market with a relevant fraction of their vacancies posted online, presented on average nearly 15% lower vacancy rate for a given unemployment rate. Therefore, for these sub-segments, the Beveridge curve shifted inwards due to efficiency enhancements. These findings support active search policies to reduce information barriers, which reduce the odds of firms and workers finding one other in the labor market. Policies as those implemented by the Public Employment Service in Colombia seem to be beneficial.
