Art of Camouflage
by Sara PowerA powerful debut about the lives of women and girls caught in the orbit of the military.Female recruits weathering toxic masculine environments. Military wives stretched thin across countless military moves, new cities and new selves. Military kids whose mercurial friendships flare and fade to the rhythm of their parent's career path. Throughout, this collection introduces us to characters who trespass beyond the boundaries of their own realities to discover who they are within someone else's narrative.Sara Power writes with insight and emotional precision about what it's like to be unmoored. Art of Camouflage is memorable at every turn, full of characters whose deepest motivations we recognize intrinsically as our own.
The Harvesters
by Jasmina OdorSet in Paris, an offbeat and sweet novel about family, loss and recovery, and the magic of memory.When Mira takes a trip to Paris with her nephew, Bernard, she expects to ride bicycles through the picturesque streets and admire the parks and courtyards. But the trip takes a different turn when the two travellers try to rescue an injured pigeon from the sidewalk, and their journey becomes one of addressing the losses that define their lives.Mira is recently divorced and facing a childless (or is it child-free?) future; Bernard has lost his first love and is grappling with his responsibility in the relationship's demise. Both are living in the shadows of war, immigration, and family disconnection as they prepare to travel on to Croatia, the country Mira left behind during the Yugoslav Wars.But for now: Paris. Mira and Bernard move through a city that feels both familiar and strange -- this is not merely the Paris of postcards, but a Paris of dubious one-star hotels and immigrants and labourers and taxi drivers and Eiffel Tower trinket vendors. And yet it's still a city that possesses an undeniable magic, where one might glimpse intriguing strangers or stumble upon past lovers.Thoughtful and witty, The Harvesters is infused with subtle beauty and the magic of memory.
The Pause: Experiencing Time Interrupted
by Julian Jason HaladynWhen COVID-19 spread across the globe, people experienced protection measures such as social distancing, self-isolation, and self-quarantine as a kind of shutting down or putting on hold of life. Many referred to this experience as a pause.Calling attention to the long history of grappling with pausing in writing on plagues and pandemics, Julian Haladyn explores the pause in its social, political, and personal manifestations over the extended pandemic. The schism between the virus and its prohibitions on human engagement with the world produced a crisis, Haladyn argues, in which, for an extended time, it was impossible to imagine a future. The Pause is a cultural inquiry into a moment when human life around the globe seemed to halt, as well as the social symptoms that defined it.The Pause captures the experience of being inside the pandemic, even as that experience continues to unfold. It regards our current situation not for what it may become in the future, but rather as a moment of mass uncertainty and existential hesitation.
Unlocking the Chinese Gate: Manifestations of the Space "In-Between" in Early China (SUNY series in Chinese Philosophy and Culture)
by Galia DorUnlocking the Chinese Gate offers an innovative analysis of gates in early Chinese thought and material culture. Observing gates from various perspectives—including philosophy, architecture, and psychology—and through the conceptual lens of Chinese correlative thinking, Galia Dor conceptualizes the Chinese gate as a membrane-like apparatus that, from the space "in-between," efficaciously manifests (de) the Way (dao) into the "ten thousand" forms of actualized life. This methodology exposes an open-to-closed gradation between pairs of inside/outside (wai/nei) that resonates throughout the Chinese model of psychocosmic concentric circles. The consequential strategies (e.g., continuity/break, chaos/order) demonstrate how early Chinese cosmological, philosophical, and political idealities, as well as afterlife religious beliefs, were applied—including the various approaches to and practices of self-cultivation. The book sheds new light on ancient Chinese thought and material culture and offers points of comparison to Western thought and modern science, including a model of "decision-gating" that carries relevant implications and insights to our current lives.
Between Care and Justice: The Passions as Social Resource (SUNY series in Contemporary Italian Philosophy)
by Elena PulciniElena Pulcini (1950–2021), an internationally renowned philosopher of care, was at the forefront of thinking and creating a new ethical framework to respond efficaciously to problems that affect individuals at a global level. This translation of Pulcini's last work addresses perhaps the two fundamental questions for our times—namely, "Why care for others when we are not bound by personal relationships?" and "Why commit to justice even when it does not personally affect us?" By focusing on passions such as indignation, fear, compassion, resentment, and love, Pulcini offers an alternative ethical perspective in which justice and care intertwine to supplement and balance each other. Together, care and justice are proven capable of addressing the challenge of the "other," distant in space (the outsider, the marginalized, and the migrant) and time (future generations). In the end, Pulcini proposes a form of moral education that nurtures and develops desirable moral sentiments for a more just world at the interpersonal, social, political, economic, and environmental levels, thereby providing an alternative social, global model to current individual-focused, rights-based, purely rationalist ethical systems.
Hopelessly Alien: The Italian Immigration Experience in Chicago Heights (SUNY series in Italian/American Culture)
by Louis CorsinoHopelessly Alien is an in-depth study of Italian immigration to Chicago Heights, Illinois, between 1910 and 1950. Drawing upon oral histories, interviews, historical documents, and census materials, Louis Corsino examines the critical concept of hope, which most immigration studies have cast in privatized, psychological terms as the motivation to emigrate in search of a better life. This investigation offers a more contentious, sociological perspective, depicting hope as both an ideological lure to recruit and manage the "foreign element" and as a resource immigrants employed to purchase acceptance and avoid a disparaging label as a "hopelessly alien" stranger. These dialectical processes are illustrated through the Italian immigrants' pursuit of occupational mobility and homeownership, and the appropriation of their children's hopes. Each became forms of cultural capital that demonstrated a public commitment to the American ethos of "joyful striving." Each provided measures of success, but these individual pursuits came at the expense of upsetting the necessary tension between individual and communal hopes.
The Algonquin Round Table: 25 Years with the Legends Who Lunch (Excelsior Editions)
by Konrad BercoviciLocated in New York's theatre district, the Algonquin Hotel became an artistic hub for the city and a landmark in America's cultural life. It was a meeting place and home away from home for such luminaries as famed wits/authors Alexander Woollcott and Dorothy Parker; Broadway and Hollywood stars, including Tallulah Bankhead and Charles Laughton; popular raconteurs like Robert Benchley; and New York City mayors Jimmy Walker and Fiorello LaGuardia. Observing it all was celebrated author and journalist Konrad Bercovici. Born in Romania, Bercovici settled in New York, where he became known for reporting on its rich cultural life. While digging through an inherited trunk of family papers, his granddaughter, Mirana Comstock, discovered this previously unpublished manuscript on Bercovici's years at the Algonquin Round Table. Lovers of New York lore and fans of American culture will enjoy his vivid, intimate accounts of what it was like to be a member of this distinguished circle.
Soundings in Context: Poetry's Embodiments (The University at Buffalo Robert Creeley Lectures in Poetry and Poetics)
by Judith Goldman James MaynardSoundings in Context brings together the second and third University at Buffalo Robert Creeley Lectures in Poetry and Poetics by the renowned literary and textual scholar Jerome McGann, and the innovative, prolific Canadian poet, essayist, and novelist Lisa Robertson, respectively. The volume's first half presents McGann's "Reading (I Mean Articulating) Poetry, a Multi-Player Game," with responses by Nikolaus Wasmoen and Steve McCaffery; the second presents Lisa Robertson's "Dous Chantar: Refrain for a Nightingale," with responses by Shannon Maguire and Liz Howard. Initially given at different moments and since revised, the pieces considered in the lectures range widely, moving from the Romantics and medieval troubadour poetry to T. S. Eliot, Jackson Mac Low, Jacques Rouboud, and far beyond. Still, they are collectively concerned with questions of voice, recitation, and reception in different contexts; with sonic patterning and its modes of significance; and with foregrounding an embodied experience of oral and written language as opposed to its interpretation. McGann, Robertson, and their interlocutors all propose affective, pragmatic approaches to poetry that allow it to surface as materially formative, alive and lived. Reading their contributions together offers an opportunity to see how these values present themselves in differing cultures of poetic scenography across space and time.
The Serpent's Plumes: Contemporary Nahua Flowered Words in Movement (SUNY series, Trans-Indigenous Decolonial Critiques)
by Adam W. CoonThe Serpent's Plumes analyzes contemporary Nahua cultural production, principally bilingual Nahuatl-Spanish xochitlajtoli, or "poetry," written from the 1980s to the present. Adam W. Coon draws on Nahua perspectives as a decolonizing theoretical framework to argue that Nahua writers deploy unique worldviews—namely, ixtlamatilistli ("knowledge with the face," which highlights the value of personal experiences); yoltlajlamikilistli ("knowledge with the heart," which underscores the importance of affective intelligence); and tlaixpan ("that which is in front," which presents the past as lying ahead of a subject rather than behind). The views of ixtlamatilistli, yoltlajlamikilistli, and tlaixpan are key in Nahua struggles and effectively challenge those who attempt to marginalize Native knowledge production.
Geophilosophy of the Mediterranean (SUNY series in Contemporary Italian Philosophy)
by Caterina RestaThe essays collected here outline a geophilosophy of the Mediterranean—a sea of great importance in the history of Europe and the wider West. Conceived from a geophilosophical perspective, the Mediterranean is a sea surrounded by lands—that is, a "pluriverse" of different cultures and religions, which have often become entangled in conflicts. Nevertheless, they have also demonstrated a remarkable capacity for coexistence, as exemplified by multilingual, multiethnic, and multireligious Sicily during the reign of Roger II of Hauteville. Throughout its millennia-long history, the Mediterranean has consistently displayed a profoundly unified configuration despite its inherent diversity. Its distinctive blend of singularity and plurality can serve as a paradigm for rethinking new forms of social and political coexistence, not only for Europe, which draws its origin from this sea, but also for a new global order.
Through a Nuclear Lens: France, Japan, and Cinema from Hiroshima to Fukushima (SUNY series, Horizons of Cinema)
by Hannah HoltzmanThe Franco-Japanese coproduction Hiroshima mon amour (1959) is one of the most important films for global art cinema and for the French New Wave. In Through a Nuclear Lens, Hannah Holtzman examines this film and the transnational cycle it has inspired, as well as its legacy after the 2011 nuclear disaster at Fukushima Daiichi. In a study that includes formal and theoretical analysis, archival research, and interviews, Holtzman shows the emergence of a new kind of nuclear film, one that attends to the everyday effects of nuclear disaster and its impact on our experience of space and time. The focus on Franco-Japanese exchange in cinema since the postwar period reveals a reorientation of the primarily aesthetic preoccupations in the tradition of Japonisme to center around technological and environmental concerns. The book demonstrates how French filmmakers, ever since Hiroshima mon amour, have looked to Japan in part to better understand nuclear uncertainty in France.
When History Returns: Psychoanalytic Quests for Humane Learning (SUNY series, Transforming Subjects: Psychoanalysis, Culture, and Studies in Education)
by Deborah P. BritzmanWhen History Returns brings together psychoanalytic theories of learning with the antinomies of social strife. From a psychoanalytic perspective, history returns through transitional scenes of inheriting a past one could not make, experiencing a present affected by what came before, and facing a future one can neither know nor predict. Taking such scenes as the subject of education, Deborah P. Britzman provides new approaches and vocabulary for conceptualizing experience and understanding, as expressed in psychoanalysis, literature, film, clinical case studies, and warm pedagogy. Britzman argues that novel quests for humane responsibility take hold in the fallout of understanding, in the feel of history, in imaginative dialogues and missed encounters, and in searches for friendship, belonging, and affiliation. Each chapter charts these quests in contemporary education, carrying readers into the heart of learning and the emotional situations that urge the transitions of difficult knowledge into care for thinking and the questions that follow.
Class-Conscious Coal Miners: The Emergence of a Working-Class Movement in Central Pennsylvania (SUNY series in Labor Studies)
by Alan J. SingerBituminous coal miners in Central Pennsylvania were among the most militant and class-conscious workers in the United States in the post-World War I era. Class-Conscious Coal Miners examines the development of working-class consciousness as they fought to sustain their union, jobs, communities, and work pejoratives, what they described as the Miner's Freedom, against mechanization and operator open shop drives in the 1920s. Their struggles brought them into conflict with coal companies, a pro-business federal government, and the business-unionist leadership of the United Mine Workers of America. After the collapse of the bituminous coal industry in Central Pennsylvania starting in the 1950s, working-class consciousness gradually diminished until, in the present century, there has been a marked shift toward political conservatism.
Superstition, Management and Organisations: Irrationality, Randomness, and Chaos in Decision Making (Palgrave Studies in Workplace Spirituality and Fulfillment)
by Joanna CrossmanThis book addresses how people and organisations sometimes respond to uncertainty in making decisions. Those decisions are rooted in beliefs and behaviours that are not always rational, especially in response to perceived randomness, chaos and unexpected circumstances. The author uses a transdisciplinary approach to the study of superstition in the context of business and management, taking care to acknowledge that what is regarded as superstition to one person may well be constructed as a spiritual belief by another. Respect and sensitivity in explicating individual and social constructions of spirituality is a core value in structuring the narrative of the text. The work also explores the interwoven relationships amongst superstition, religion, spirituality and empiricism and how cultural, political, economic and environmental factors are likely to influence organisations and those who are employed by them. Further, it examines the influence of beliefs related to topics such as feng shui, astrology, phrenology and the I Ching in recruitment. This comprehensive treatment of the role of superstition in business will advance the scholarly conversation on uncertainty in decision making. It points to the power of belief that defies empirical validation and how it can be used in a variety of contexts, such as the marketing of products and images to manipulate unwary consumers or inhibit the implementation of health advice in times of COVID-19.

Towards Healthy Settlements: Health Implications of Residential Suburbanization in Guangzhou (Urban Sustainability)
by Tianyao ZhangThis book aims to formulate recommendations for achieving a healthy neighborhood living environment for the middle-income people in China‘s suburbs. In China, the expeditious urbanization triggers the prosperous commodity housing development, which further grows with the spatial restructuring and socioeconomic transition. Residential suburbanization is generated, accompanied with the emergence of new-middle class and the change of lifestyle. However, the health effects of suburbanization in China are overlooked. This book investigates the health performance of suburban residents and the effects of suburban living on residents‘ health. This book also examines the resident-environment transaction modes to unfold the underlying mechanism of suburban living affecting residents’ health. Suburban residents had to passively adapt to their residential environment, which is the obstacle for achieving a health-promoting environment. The institutional dynamics determining the health performance of suburban living environment were addressed with the roles of governments, developers, planners, housing managers, residents‘ committee, and ordinary residents in commodity housing development. The book found no institutional support for the creation of health-promoting environments, especially with default of governments and excessive dependence on developers for public service facilities and the absence of civil society. Thus, the book proposes that institutional innovations are necessary in term of embedding the health dimension in all sectors of the society, enlisting collaboration between public and private sectors, and between health and non-health sectors, and thus cultivating the optimization of residents-environment transactions to create health-promoting environments.
Handbuch Organisationstypen
by Maja Apelt Veronika TackeDie Organisationssoziologie ist es gewohnt, ihren Gegenstand anhand eines allgemeinen Begriffs der Organisation zu beschreiben. Zwangsläufig aber hat sie es stets mit besonderen Typen der Organisation zu tun, seien es Unternehmen, Universitäten, Verwaltungen, Kirchen, Parteien, Schulen, Krankenhäuser, Wohlfahrts- oder Protestorganisationen. Auf unterschiedlichen Ebenen der typologischen Generalisierung tragen die Beiträge des Handbuchs das Wissen über eine Vielfalt moderner Organisationen zusammen, ohne dabei grundsätzliche Fragen der einheitlichen Typologiebildung aus dem Blick zu verlieren.

Drilling Geomechanics in Naturally Fractured Reservoirs Near Salt Structures: From Pore-Pressure in Carbonates to Multiphysics Models (Springer Theses)
by Juan Pedro Morales SalazarThis book explains different phenomena that occur in Naturally Fractured Reservoirs (NFRs) of carbonate rocks neighboring a salt structure and how it affects well drilling. Prediction of carbonate pore pressure is difficult; therefore, a new set of pore pressure equations for carbonates were developed, accounting for overpressure and depleted conditions. A detailed description of a fully coupled model is shown in order to discuss geomechanics and the coupling of fluid flow in porous media and to achieve a better representation of the mechanics involved in the exploitation of NFRs. Additionally, results of a new model of geomechanics in vuggy carbonate reservoirs are presented. This book also displays a wide discussion, analysis, and numerical implementation of six different salt rheology models. Furthermore, the most representative rheology salt models were studied aside with the fully coupled model of geomechanics and fluid flow in porous media. Finally, it presents an answer to areal case of a well drilled near a salt diapir where anomalous pore pressure was found.
Gamification in A Flipped Classroom: Pedagogical Methods and Best Practices
by Zamzami Zainuddin Samuel Kai Chu Corinne Jacqueline PereraThis book introduces to researchers and teaching practitioners the concept of gamification within a flipped classroom setting, which resonates with the best practices of flipped learning, gamified learning, and gamified flipped learning. The gamified flipped learning (flipped learning plus gamification) approach combines two emerging pedagogies into a single pedagogical form of instruction and serves as an alternative resolution to counter the challenges that arise from flipped learning and gamified learning as separate pedagogies. This book also examines assessment systems for flipped classrooms, showcases various examples of gamification in flipped classroom designs, and reviews educational applications containing game elements for a flipped classroom setting.

Computational Fluid Dynamics: Finite Difference Method and Lattice Boltzmann Method (Engineering Applications of Computational Methods #20)
by Guoxiang Hou Caikan Chen Shenglei Qin Yuan Gao Kai WangThis book provides a concise and comprehensive introduction to several basic methods with more attention to their theoretical basis and applications in fluid dynamics. Furthermore, some new ideas are presented in this book, for example, a method to solve the transition matrix by difference operator transformation. For this method, the book gives the definition of Fourier integral transformation of translation operator, and proves the transition matrix equaling to the differential operator transformation, so that it is extended to general situations of explicit, implicit, multi-layer difference equations, etc. This flexible approach is also used in the differential part. In addition, the book also includes six types of equivalent stability definitions in two ways and deeply analyzes their errors, stabilities and convergences of the difference equations. What is more important, some new scientific contributions on lattice Boltzmann method (LBM) in recent years are presented in the book as well. The authors write the book combining their ten years teaching experience and research results and this book is intended for graduate students who are interested in the area of computational fluid dynamics (CFD). Authors list some new research achievements, such as simplified lattice Boltzmann method, the simplified lattice Boltzmann flux solver and discrete unified gas kinetic scheme, and expect that this new information could give readers possible further investigating ideas in their future research on CFD area.

Gestaltungsmöglichkeiten zukünftiger lokaler Energiemärkte (BestMasters)
by Jan N. TocklothLokale Energiemärkte können zukünftig eine der zentralen Maßnahmen der Energiewende sein, sind bisher jedoch kaum verbreitet. Durch die Einbindung einer Vielzahl von Letztverbrauchern in den Energiehandel, sind lokale Energiemärkte in der Lage, die Akzeptanz der Bevölkerung gegenüber der Energiewende zu steigern und somit die Transformation der Energiesysteme zu beschleunigen. Dieses Buch definiert erstmals die verschiedenen Arten lokaler Energiemärkte, grenzt andere Marktkonzepte ab und unterscheidet dabei zwischen verschiedenen Energieformen. Bestehende Konzepte für Peer-to-Peer Märkte, Community Self Consumption Märkte und lokale Systemdienstleistungsmärkte werden analysiert und darauf aufbauend Gestaltungsmöglichkeiten zukünftiger Marktkonzepte identifiziert. Mithilfe des entwickelten Energiemarkt Reengineering Frameworks können lokale Energiemärkte nach einem Baukastenprinzip konzeptioniert werden. In einem nachgelagerten Schritt können die Konzepte auf verbleibende technischeund rechtliche Hürden untersucht werden. Jan N. Tockloth stellt ein umfangreiches Werk zur Verfügung, das einen niederschwelligen Einstieg in lokale Energiemärkte ermöglicht und diese im energiewirtschaftlichen Kontext einordnet. Die detaillierten Inhalte und entwickelten Methoden bieten gleichzeitig einen praktischen Nutzen für Leserinnen und Leser aus den Bereichen Forschung, Energiewirtschaft und Politik.
