ABSTRACT

Background
One of the challenges in living kidney donor screening is to estimate remaining kidney function after donation. Here we developed a new model to predict post-donation measured glomerular filtration rate (mGFR) from pre-donation serum creatinine, age and sex.

Methods
In the prospective development cohort (TransplantLines, n = 511), several prediction models were constructed and tested for accuracy, precision and predictive capacity for short- and long-term post-donation 125I-iothalamate mGFR. The model with optimal performance was further tested in specific high-risk subgroups (pre-donation eGFR &lt;90 mL/min/1.73 m2, a declining 5-year post-donation mGFR slope or age &gt;65 years) and validated in internal (n = 509) and external (Mayo Clinic, n = 1087) cohorts.

Results
In the development cohort, pre-donation estimated GFR (eGFR) was 86 ± 14 mL/min/1.73 m2 and post-donation mGFR was 64 ± 11 mL/min/1.73 m2. Donors with a pre-donation eGFR ≥90 mL/min/1.73 m2 (present in 43%) had a mean post-donation mGFR of 69 ± 10 mL/min/1.73 m2 and 5% of these donors reached an mGFR &lt;55 mL/min/1.73 m2. A model using pre-donation serum creatinine, age and sex performed optimally, predicting mGFR with good accuracy (mean bias 2.56 mL/min/1.73 m2, R2 = 0.29, root mean square error = 11.61) and precision [bias interquartile range (IQR) 14 mL/min/1.73 m2] in the external validation cohort. This model also performed well in donors with pre-donation eGFR &lt;90 mL/min/1.73 m2 [bias 0.35 mL/min/1.73 m2 (IQR 10)], in donors with a negative post-donation mGFR slope [bias 4.75 mL/min/1.73 m2 (IQR 13)] and in donors &gt;65 years of age [bias 0.003 mL/min/1.73 m2 (IQR 9)].

Conclusions
We developed a novel post-donation mGFR prediction model based on pre-donation serum creatinine, age and sex.
Introduction
Authors: Dove Guy 
Published: June 2022

Abstract
This chapter introduces the theoretical notion of a concept. Concepts are bodies of knowledge that are quickly accessed in various situations. Sorting the world into categories enables us to recall and use information that we have gathered over time. We use concepts to recognize patterns, draw inferences, make decisions, and understand word meanings. In this chapter, the author explains why researchers think that our concepts might be grounded in action, emotion, and perception systems and why abstract concepts threaten this proposal. A road map for the arguments contained in the book is provided. The author contends that researchers need to explore the diverse sources of grounding, the influence of higher-level representations, and the ways in which concepts are shaped by social factors and situations.
Contesting the Last Frontier
Authors: Lien Pei-te , Filler Nicole 
Published: June 2022

Abstract
This book examines the scope and significance of the rise of Asian (and Pacific Islander) Americans in US elective office over the past half-century. By scrutinizing the political trajectory of pioneering figures and their significant followers in each of the major Asian ethnic communities, this book provides unprecedentedly broad and detailed coverage of the development of the electoral landscape of the relatively unknown community in American politics. This book aims not only to fill a missing piece of American electoral history but to challenge the “model minority” and “perpetual foreigner” tropes of Asians in American society and politics. To help interpret the complex experiences of these political women and men situated at the intersection of race, gender, and other dimensions of marginalization, this book adopts an intersectionality framework that puts women of color at the center of storytelling and analysis. Our account includes their trajectories to office, their divergent patterns of political socialization, the barriers and opportunities they faced on the campaign trail, and how these elected officials enacted their roles as representatives at local, state, and federal levels of government. This book documents how Asian immigrants of various origins and those born on US soil strived to serve the interests of the rapidly expanding and majority-immigrant population, especially those disadvantaged by the intersections of gender, ethnicity, and nativity. Our research demonstrates the intrinsic values of the feminist/womanist leadership praxis in illuminating the meanings and significance of political representation and leadership for Asians and other nonwhite American women and men in elective office.
Introduction
Authors: Lien Pei-te , Filler Nicole 
Published: June 2022

Abstract
This introductory chapter begins by laying out the complexity and inherent contradictions in studying the political experiences of the Asian American community. It justifies the need for employing intersectionality as a framework for the analysis and womanist leadership praxis as a model of social justice-focused political representation rooted in the Asian American movement and other social movements and grassroots activism of Black and other women of color. It also argues for the need to identify an Asian American version of the womanist leadership praxis for advancing social justice and uses it as a filter to screen elected officials for inclusion and focused interpretation in our narration. In addition, it defines the notion of political incorporation for Asian Americans and discusses how their political representation needs to be assessed both quantitatively and qualitatively with different indicators and over time.
Evolution of the Electoral Landscape
Authors: Lien Pei-te , Filler Nicole 
Published: June 2022

Abstract
This chapter provides an aggregate-level view of the evolution of the electoral landscape that began in the territory and state of Hawaii. It analyzes the growth and transformation of the population structure of the APA community since 1965 to help contextualize continuities and changes in the contours and makeup of the population of APA elected officials (APAEOs) between 1980 and 2020. The chapter appraises the various gaps in descriptive representation by gender, ethnicity, and nativity among APAEOs across levels of offices nationwide and between Hawaii and California, the top two states in the number of APAs elected to offices. Then, focusing on Asian city council members in California and using data collected over eight time points, the chapter appraises sustainability issues in their political incorporation and the relationship between demography and representation over time. It also examines the significance of local officeholding in political ascension and assesses the facilitating role of term limits.
Large Stones—Big Challenge?
Authors: Rheidt Klaus 
Published: June 2022

Abstract
The production and, most especially, the transportation of very large stones were always opportunities for spectacle in preindustrial times. The Egyptian obelisks in Rome as well as the Thunder Stone of St. Petersburg are outstanding examples of phenomenal efforts against gravity undertaken by Roman emperors or by Catherine the Great to demonstrate that imperial power and skilled engineering were at an apex. The largest ashlar blocks ever placed into a wall were set up in Baalbek, Lebanon. To move those megaliths, some 500 to 1,000 tons in weight, and to put them into place required highly experienced stone masons and complex machinery—a considerable technical challenge accompanied by spectacular scenes of transportation. Are the Baalbek megaliths, as well, witnesses of Roman power in the Levant? Or does the use of very large stones merely follow a structural rationale? This chapter aims to position the megalithism of Baalbek between design and construction and between skilled workmanship, architectural expression, and imperial power.
Creating “Hanging Gardens”
Authors: Wulf-Rheidt Ulrike 
Published: June 2022

Abstract
Though famous as one of the Seven Wonders of the Ancient World, the Hanging Gardens have yet to be securely located. Undaunted, many artists, architects, and scholars have suggested reconstructions with the help of descriptions in Greco-Roman literature, such as the illustration by the Dutch artist Maerten van Heemskerck. In his depiction, the gardens are very similar in appearance to the so-called Domus Severiana, one part of the imperial palace in Rome along the Circus Maximus, which clearly inspired van Heemskerck’s reconstruction. The idea of a flourishing artificial garden, rich with water, situated within a metropolis simmering in the desert heat has proven fascinating, not only in recent times but already in antiquity, when it had an enduring influence on both landscape architecture and on Roman palace architecture. The main floor of the Domus Aurea, and subsequently also of the palaces on the Palatine, stood atop high substructures and thus dominated the surrounding city while offering those within a privileged view. Integrating a variety of water installations into these large platforms increased the sense of an artificial landscape in the form of a “hanging garden.” Thus, vague and often fantastic ideas like those about the design of the Hanging Garden of Babylon inspired Roman builders and their architects and led the art of building Roman villas and imperial palaces to new heights.
Reconstructions of Roman Polychrome Architecture
Authors: Zink Stephan 
Published: June 2022

Abstract
Efforts to understand polychromy in Roman architecture must address two inherent challenges: first, documenting surface finishes for Roman monuments is difficult when that evidence is scarce and scientific methods of evaluation are continually developing. Second, interpreting and presenting that evidence is far from straightforward. This chapter examines how the presentation of evidence for polychromy was deeply shaped by both the ideology and ideals of the 19th and early 20th centuries. Scholars today still hew to paradigms set decades earlier, often without any awareness of the cultural and historic forces that lie behind their choices. To address these issues, the careful study of architectural polychromy needs to be reintegrated into Roman Bauforschung.
Limit Situations (of the Digital)
Authors: Lagerkvist Amanda 
Published: June 2022

Abstract
This chapter demonstrates the key objective of the book: to restore Karl Jaspers’s existential philosophy for media theory, and to bring its key concerns about what it means to exist, into a serious conversation with media studies. This chapter discusses and expands on Jaspers’s concept of the limit situation and seeks to demonstrate its potential for understanding media life beyond the habitual and the banal. It further expands on the concept by suggesting that our age is in effect a digital limit situation, in which there are essential ethico-political and existential stakes of media. The digital limit situation thereby offers both a reality and a heuristic. The chapter begins with a brief introduction of Jaspers’s philosophy and its reception, as well as the key development of his philosophy, and his thinking on technology, to then go into his ideas about the limit situation as formative for being human in the world. This will be followed by expanding on his thinking to begin to describe the key traits of the digital limit situation, in light of the aims of existential media studies to demonstrate how originary technicity relates to originary human vulnerability. Finally, by having provided substantial definition of the digital limit situation—as both an irreducible reality and a heuristic—the chapter then deepens the theorization by thinking further about limits, which allows for introducing the essays at the heart of Part II of this book.
Existential Media Studies
Authors: Lagerkvist Amanda 
Published: June 2022

Abstract
This chapter offers a rigorous anchorage of existential media studies in the legacies of existentialism. It includes an overview of the historical lineages of existential media studies, through an introduction to existential philosophy and phenomenology and its key concerns across time, while stressing how media relate to them, and thereby showing how media have always been existential. The chapter also shows some straightforward senses in which classic existential themes—reflected in staple notions of meaning, time, subjectivity, and community—relate to media. The chapter discusses how three other principal themes within the tradition of existential philosophy—death, ontology, and responsibility—have been addressed in media theory, and identifies some of their distinctive features in the digital era. It shows that the field of media and communication studies suffers from an existential deficit, and then explores some of the exceptions, including the turn to ontology and to Martin Heidegger’s philosophy. It discusses how they relate to the two main emphases in existentialism: the moral (subjectivist, exceptionalist strand) and the material (communitarian, historicist strand). This is followed by an introduction to how Jaspers’s philosophy and philosophy of communication balances and mediates between the two strands. The chapter discusses newer lines of scholarship on vulnerability, providing a deliberation on Jaspers’s idea of existential communication in our time of connective capitalism, affective media landscapes, and datafication of the digital limit situation. The chapter also lays claim to existential vulnerability in the place of tactical forms of vulnerability in intimate publics of our time.
To Receive from Each Other, First Receive Each Other
Authors: Jones Sarah Rowland 
Published: June 2022

AbstractIf the primary motivating questions of Receptive Ecumenism have been for an ecclesial tradition to ask itself ‘What are we lacking?’ and ‘What do we need to receive from others?’, the counterpart questions which have motivated movements such as the Global Christian Forum are ‘Whom are we lacking?’ and ‘Whom do we need to receive—and by whom do we need to be received?’. While both stances have sought to subvert traditional ecumenical practices focussed on what divides, the latter also deliberately moves the emphasis away from faith and order questions towards more relational, affective, even pneumatological engagement, often expressed through witness and testimony exchanged in narrative form. Recognizing through this that those previously considered strangers are brothers and sisters in Christ opens new doors and brings new challenges. It has refreshed existing ecumenical relationships. It has connected with Christians whose understanding of faith is less centred on theological and ecclesiological formulations. Answering St Paul’s call to Christians to welcome—or receive—one another, just as Christ has received us, for the glory of God (Rom. 15:7), takes on new possibilities.
Ecumenical Involvement between US Black and White Churches Revisited
Authors: Barnes Sandra L. 
Published: June 2022

AbstractThis chapter revisits the author’s 2009 study on the relationship between denominational, theological, and organizational indicators and ecumenism between Black and White churches in the United States. Findings then suggested that denominational and organizational indicators were consistently important in explaining ecumenism. Black churches associated with the Presbyterian, United Methodist, and African Methodist Episcopal Zion traditions were more likely than Baptists to engage in ecumenism. Black congregations which had larger memberships, were in rural areas, were frequently exposed to sermons about racial issues, and which were led by formally educated pastors were more ecumenically involved. Over ten years later, does similar cross-racial engagement occur? What factors precipitate ecumenism and/or undermine it? Informed by Receptive Ecumenism, this chapter identifies opportunities and obstacles across both Black and White churches that influence ecumenism, examples of racial reconciliation, and the implications of increased racial challenges, disparities, and unchecked historic wounds nationally. A mixed-methodological, multi-disciplinary approach, referencing current scholarship and mainstream reports, is used to update the original study in light of contemporary US race relations.
Receptive Ecumenism in a Latin American Context
Authors: Casarella Peter J. 
Published: June 2022

AbstractThe question of Mary has been seen as an intractable problem in both Latinx and Latin American contexts, and requires a new approach. In both Pentecostal and Baptist communities in Latin America, for example, the Catholic devotion to Mary is seen as an alternative to and replacement for a Christ-centred faith and form of worship. Without attention to reception, this problem is impossible to address since it is very specific to context and cultural attitudes. This chapter attempts to glean wisdom from Jerry Sandidge—a Pentecostal theologian who engaged the Roman Catholic teaching on Mary—and Ralph del Colle and Jeffrey Gros—Catholic theologians who addressed Pentecostal attitudes to Mary. The offering of insights from both sides is a way to get a conversation started about Receptive Ecumenism. Insights are offered from Latinx theology and the Argentine ‘theology of the people’ to reconfigure the question of Mary and ecumenism in such a way that the reception of the doctrines among the Spanish-speaking communities comes to play a larger and more determinative role in our thinking about Christian unity.
Background part A
Authors: McMaster Brian , McCluskey Aisling 
Published: June 2022

Abstract
Here is presented a concise summary of aspects of real analysis that serve as background to the study of the corresponding concepts in the context of complex numbers. This includes the language and notation of very elementary set theory, limit behaviour for a convergent sequence and of subsequences, series convergence and absolute convergence (of power series in particular) and basic convergence tests for series—comparison tests, the nth root test, the ratio test, the alternating series test.
Paths in the complex plane
Authors: McMaster Brian , McCluskey Aisling 
Published: June 2022

Abstract
The central idea here is that of integrating a complex function along an appropriate path in the complex plane. To this end we describe and categorise paths, including closed, simple, smooth and piecewise smooth paths (contours), and the operations on paths of concatenation and reversal (the opposite path). Connected sets, star-shaped sets and domains are explained. These ideas lead to the integral along a contour, and to the effects that concatenation and reversal have upon contour integrals. Path length is introduced and used in (over)estimating the modulus of a contour integral.
Residues
Authors: McMaster Brian , McCluskey Aisling 
Published: June 2022

Abstract
In this chapter we encounter Laurent’s theorem and, in particular, the principal part of a Laurent expansion, uniqueness of the coefficients and the key idea of residues. Laurent then allows us to classify singularities into removable singularities, poles of various orders and isolated essential singularities, and to investigate functions’ characteristic behaviour near to a singularity of each class. Cauchy’s residue theorem leads to a number of useful residue calculation tools, especially at simple poles (poles of order 1).
Reality from complexity
Authors: McMaster Brian , McCluskey Aisling 
Published: June 2022

Abstract
Here we reach the text’s central message, that many difficult real integrals can be evaluated by complex methods that are often simpler or less ad hoc than purely real methods—if, indeed, any of the latter are even readily available. Demonstrated techniques include contour integration around the unit circle, around an infinite semicircle and around indented contours. We show how to handle trigonometric or exponential factors in the integrand by appealing to Jordan’s inequality and Jordan’s lemma. Some more specialised contours are also mobilised, including an evaluation of the Gaussian integral.
The repair shop for broken promises
Authors: McMaster Brian , McCluskey Aisling 
Published: June 2022

Abstract
The final chapter deals with peripheral or more demanding issues that were skimmed over in the main text in order not to lose momentum there. Included are a brief discussion of the field axioms, a careful exploration of pointwise and uniform convergence of a sequence of functions on a set, including the Weierstrass M-test, and an account of interchanging summation and integration focusing on its role in the proofs of Taylor’s and Laurent’s theorems.
The Veil of Perception and Kant’s Transcendental Idealism
Authors: Wilson Catherine 
Published: June 2022

Abstract
According to the corpuscularian philosophy, our experiences are not iconic copies of scenes in the external world, but constructions of the mind than enable us to survive in it. The nature of the world outside the mind can only be inferred, since we are aware only of our ideas. Kant agreed with the majority of 18th century philosophers of science that we are aware only of ‘appearances’, which present themselves as external to us, and he denied that material corpuscles could be the substance of the external world and the true ground of our experiences. He went farther in arguing that space and time were only the ‘forms of intuition’ that constrained our human sensory perceptions of an external world. Although distinguished from both Platonic and Berkeleyan idealisms, Kant’s theory was motivated by an analogous repulsion from materialism.
The Promise of Political Settlements Analysis (PSA)
Authors: Kelsall Tim , Schulz Nicolai , Ferguson William D. , vom Hau Matthias , Hickey Sam , Levy Brian 
Published: June 2022

Abstract
Few concepts have captured the imagination of the conflict and development community in recent years as powerfully as the idea of a ‘political settlement’. At its most ambitious, ‘political settlements analysis’ (PSA) promises to explain why conflicts occur and states collapse, the conditions for their successful rehabilitation, different developmental pathways, and how to better fit development policy to country context. As such, it provides an analytical framework for development agencies increasingly tasked with working in fragile and conflict-affected states, and frustrated by frequently disappointing ‘good governance’ results in more stable ones. Yet despite the approach’s tremendous promise, not all is well in the world of PSA. Rival definitions of the concept abound, there are disagreements about its scope and the way it should be used, a growing schism between conflict specialists and economists, basic concepts are ambiguous, and little progress has been made on measurement. As an introduction to the book, this chapter provides a genealogy of PSA, situating it within a wider ‘post-institutionalist turn’ in development studies, before providing illustrations of some PSA highlights, problems to date, and proposals for a way forward.
