Books on the topic 'Temporal visual area'

Temporary urbanism has become a distinctive feature of urban life after the 2008 global financial crisis. This book offers a critical exploration of its emergence and establishment as a seductive discourse and as an entangled field of practice encompassing architecture, visual and performative arts, urban regeneration policies and planning. Drawing on seven years of semi-ethnographic research, it explores the politics of temporariness from a situated analysis of neighbourhood transformation, media representations and wider political and cultural shifts in austerity London. Through a longitudinal engagement with projects and practitioners, the book tests the power of aesthetic and cultural interventions and highlights tensions between the promise of vacant space re-appropriation and its commodification. Against the normalisation of ephemerality, it presents a critique of the permanence of temporary urbanism as a glamorisation of the anticipatory politics of precarity which are transforming cities, subjectivities and imaginaries of urban action.

Visual Fields: Examination and Interpretation, 3rd edition contains revisions and updates of earlier material as well as a discussion of newer techniques for assessing visual field disorders. The book begins with a short history of the field of perimetry and goes on to present basic clinical aspects of examination and diagnosis of visual field defects in the optic nerve, optic disc, chorioretina, optic chiasm, optic tract, lateral geniculate field bodies, and the calcarine complex. Additional aspects of visual field examination are explored including those of monocular, binocular, and junctional field defects, congruity vs. incongruity, macular sparing vs. macular splitting, density, wedge-shaped homonymous field loss, and monocular temporal crescent. Various new techniques of automated perimetry are also considered including SITA, FASTPAC, and SWAP. This volume provides a very useful overview of the techniques of visual field examination in a number of eye disorders and will be of interest to all ophthalmologists, neuro-opthalmologists, retina specialists, and optometrists.

The main argument of the book is as follows: (1) The descriptive premise: The phenomenology of vision is best described as an ongoing process of anticipation and fulfillment. (2) The empirical premise: There are strong empirical reasons to model vision using the general form of anticipation and fulfillment. (AF) Conclusion: Visual perception is an ongoing process of anticipation and fulfillment. The book consists of three parts and an appendix. The first part of the book makes the case for premise (1) based on descriptive claims about the nature of first-person experience. The initial support for (1) in Chapter 2 is based on the fact that visual experience has the general features of being perspectival, temporal, and indeterminate. Chapter 3 includes an argument for (1) based on the possibility of surprise when appearances do not change as we expect, and Chapter 4 contains a discussion of the content of visual anticipations. The second part of the book focuses on empirical support. Chapter 5 covers a range of evidence from perceptual psychology that motivates premise (2). Chapter 6 turns to evidence from neuroscience, including recent work in predictive coding. The seventh chapter shows how evidence for the two-visual systems hypothesis can be re-interpreted in support of (2). The third part of the book turns to general methodological questions (Chapter 8) and the relationship between visual perception and social cognition (Chapter 9). The appendix addresses the ways in which Husserlian phenomenology relates to the main theme of the book.

Frisby and Stone have dubbed adaptation the “psychophysicist’s electrode” and John Mollon once famously said, “If it adapts, it’s there.” Psychologists piously hope that their many experiments on visual adaptation will tell physiologists where to look inside the brain. This chapter describes visual adaptation to temporal ramps, spatial edges, and apparent motion and touches on kinesthetic aftereffects from jogging. Sawtooth adaptation, a ramp aftereffect that is produced by gazing at a spatially uniform patch whose luminance is temporally modulated by a repetitive sawtooth, either gradually dimming and turning sharply back on (rapid-on) or gradually brightening and turning sharply back off (rapid-off), is discussed. Related concepts that are covered include pattern-specific contrast adaptation, contour adaptation, adaptation to apparent motion, and adapting to flicker, which changes apparent spatial frequency.

This chapter explores the dual concern with causality and time in historical-institutionalism using a graphical approach. Conceptualizing causes as filters, the chapter analyses three concepts that are central to this field: critical junctures, gradual change, and path dependence. The analysis makes explicit and formal the logic underlying studies that use these “causal-temporal” concepts. The chapter shows visually how causality and temporality are linked to one another in varying ways depending on the particular pattern of change. Through this unifying visual grammar, the chapter also outlines an approach that can accommodate and reconcile both models of critical junctures and gradual change. The chapter provides new tools for describing and understanding change in historical institutional analyses.

Planning and execution of goal-directed actions are closely related to visual attention. This chapter gives an overview of research on this relationship, focusing on the role of attention in the preparation of eye movements, manual reaching, and grasping. The studies suggest that major functions of attention during motor planning are to select the spatial goals of the movement, and to prioritize those visual features that are important for the action. For complex movements involving more than a single spatial location, it seems that action preparation comes along with a temporally changing ‘attentional landscape’ which includes multiple foci of attention.

Chapter 4 examines Ellison’s use of rhythm—specifically his incorporation of polyrhythms and his application of an advanced rhythmic concept called metric modulation—to express his beliefs about virtual temporalities and social change. The chapter illustrates how Ellison often places temporal constructs, including the static time of official history and the dynamic time of duration, into polyrhythmic relation in order to challenge an entrenched ideology of historical determinism. This process, and the critique that emerges from it, depend upon a related rhythmic concept, metric modulation, which creates metronomic instability within a musical composition and, in so doing, produces nodes of temporal bifurcation. Ellison’s use of polyrhythms and metric modulation are, like his ekphrastic references to the visual media examined in Chapters 2 and 3, expressions of his commitment to dynamic time and to the promotion of social changes that the actualization of hitherto virtual temporalities makes possible.

Awake craniotomies are performed when the site of surgical instrumentation or resection directly involves or abuts eloquent areas of the brain and require a cooperative patient, a tailored neuroanesthetic technique, and good teamwork. Eloquent cortex refers to any cortical region in which injury produces a symptomatic cognitive or motor deficit and includes the primary sensorimotor cortex, essential speech areas, occipital visual areas, and mesial temporal regions crucial for episodic memory. An awake patient allows for intraoperative testing of motor, speech, or sensation function while removing or manipulating brain tissue. The two principal aims of resection of a brain tumor or an epileptic focus are to maximize excision of the offending lesion for better prognosis while minimizing or avoiding damage to surrounding brain tissue. Damage to adjacent brain tissue can be catastrophic, especially if the tumor or epileptogenic areas are located close to the eloquent regions of the brain.

Large-vessel vasculitis includes giant cell arteritis (GCA) and Takayasu's arteritis (TAK). GCA affects patients aged over 50, mainly of white European ethnicity. GCA occurs together with polymyalgia rheumatica (PMR) more frequently than expected by chance. In both conditions, females are affected two to three times more often than males. GCA mainly involves large- and medium-sized arteries, particularly the branches of the proximal aorta including the temporal arteries. Vasculitic involvement results in the typical manifestations of GCA including temporal headache, jaw claudication, and visual loss. A systemic inflammatory response and a marked response to glucocorticoids is characteristic of GCA. GCA usually remits within 6 months to 2 years from disease onset. However, some patients have a chronic-relapsing course and may require long-standing treatment. Mortality is not increased, but there is significant morbidity mainly related to chronic glucocorticoid use and cranial ischaemic events, especially visual loss. The diagnosis of GCA rests on the characteristic clinical features and raised inflammatory markers, but temporal artery biopsy remains the gold standard to support the clinical suspicion. Imaging techniques are also used to demonstrate large-vessel involvement in GCA. Glucocorticoids are the mainstay of treatment for GCA, but other therapeutic approaches have been proposed and novel ones are being developed. TAK mainly involves the aorta and its main branches. Women are particularly affected with a female:male ratio of 9:1. In most patients, age of onset is between 20 and 30 years. Early manifestations of TAK are non-specific and include constitutional and musculoskeletal symptoms. Later on, vascular complications become manifest. Most patients develop vessel stenoses, particularly in the branches of the aortic artery, leading to manifestations of vascular hypoperfusion. Aneurysms occur in a minority of cases. There are no specific laboratory tests to diagnose TAK, although most patients have raised inflammatory markers, therefore, imaging techniques are required to secure the diagnosis. Glucocorticoids are the mainstay of treatment of TAK. However, many patients have an insufficient response to glucocorticoids alone, or relapse when they are tapered or discontinued. Immunosuppressive agents and, in refractory cases, biological drugs can often attain disease control and prevent vascular complications. Revascularization procedures are required in patients with severe established stenoses or occlusions.

This chapter describes one framework for teaching close reading to groups of learners. It proposes that learners focus on one narrative feature at a time—for example, time, space, voice, and metaphor—over the course of a seminar. For each feature, students read and discuss seminal conceptual writings to situate them in the classical and contemporary critical discourse. The chapter provides capsule summaries of these four narrative features that guide students in their own close reading of texts. The discussion of temporality, for example, includes theological, philosophical, scientific, and literary/narratological writings and the close reading of literary, visual arts, and musical texts that display temporal complexity. In the chapter are described particular teaching sessions in a variety of settings where learners read and respond in writing to short texts that highlight a particular narrative feature. The teaching texts and those written by students are reproduced in the chapter.

Two recent papers have presented experimental evidence against the hypothesis that there is a semantic connection between OUGHT and CAN, rather than a pragmatic and defeasible one. However, there are two flaws with their designs. One is temporal ambiguity: just asking whether “x ought to A” is underspecified as to when the obligation exists. Another is failing to distinguish between prior obligations and all-things-considered obligations. To test these potential confounds, the chapter author ran two experiments. The first paired some of the original stories with a visual timeline specifying the time of the obligation. The second flipped the wording of the original “obligated but can’t” question into the reversed: “can’t, but still obligated.” In both experiments, there were large and significant differences between the original and modified conditions. These results undermine the conclusions of the previous experiments and remain consistent with the Semantic Hypothesis.

Chapter 10 considers what is owed to noncitizens already present in the territory of democratic countries. It focuses on three groups of noncitizens: those admitted on a temporary basis, those who have been granted permanent residence, and those who have overstayed their temporary visas or entered the territory without authorization. What legal rights are these different groups of noncitizens morally entitled to? How should their claims be weighed against the right of states to control immigration? The chapter argues that the longer one lives in the territory, the stronger one’s moral claim to a more extensive set of rights, including the right to remain. The time spent living in a place serves as a proxy for the social ties migrants have developed (social membership principle) and for their contributions to collective life (fair-play principle).

Millions of Southerners left the South in the 20th Century in a mass migration that has had a lasting impact on the U.S. Leaving the South focuses on narratives by and about those who left and how those narratives challenged concepts of Southern nationhood and remade how Southernness is interpreted and represented. Identifying “the South” as an idea, this study works under the assumption that because borders are social constructs, movements of people across borders are controlled not only by physical barriers, but also by the narratives that define that movement. Framed with a look back to the Southern history of border building and a look ahead to the impact of borders in the 21^st Century, Leaving the South focuses on 20^th century Southern Border Narratives in prose, poetry, visual arts, and music and how they were used to create group affiliation, encourage divisiveness, and formulate and perpetuate new individual and group identities. Taking an expansive approach, this book crosses temporal, textual, gendering, and racial boundaries in order to examine the parallel, intersecting, and divergent narrative paths of various groups of Southerners as they left the South. In a time of calls for building a wall between the United States and Mexico, and growing nationalistic movements and isolationist tendencies around the globe, Leaving the South reflects on that friction between the human capacities to, on the one hand, build walls and, on the other, to break them down.

This chapter examines the textual, discursive, and networking politics of Indian immigrant women residing in the United States on the H-4 temporary visa, through a close reading of the discussion forum by and about these women on the community website, indusladies.com. It argues that the politics of household and networking evidenced through the discussion cultures and online practices of forum participants exemplifies the repurposing of the virtual network to foreground a particular immigrant formation articulated along relations of gender and visa-defined immigrant class. H-4 women make visible their diverse and embodied experiences of feeling like outsiders in the immigrant space. They narrate their histories of migration from India and relocation in the United States, culminating in their becoming out of place in the nonresident Indian (NRI) household. In turn, their testimonials unsettle idealized discourses of gendered NRI belonging, which mostly by absence of representation assume that the H-4 wives of H-1B professionals are happily ensconced in domestic bliss as NRI householders.

Documentation, analysis, and explanation of culture change have long been goals of archaeology. The earliest archaeological spindle graphs appeared in the 1880s and 1890s, but had no influence on subsequent archaeologists. Line graphs showing change in frequencies of specimens in each of several artifact types were used in the 1910s and 1920s. Seriograms or straight-sided spindles diagraming interpretations of culture change were published in the 1930s, but were seldom subsequently mimicked. Spindle graphs of centered and stacked columns of bars, each column representing a distinct artifact type, each bar the empirically documented relative frequency of specimens in an assemblage, were developed in the 1940s, became popular in the 1950s and 1960s, and are often used to illustrate culture change in textbooks published during the twentieth century. Graphs facilitate visual thinking, different graph types suggest different ontologies and theories of change, and particular techniques of parsing temporally continuous morphological variation of artifacts into types influence graph form. Line graphs, bar graphs, spindle diagrams, and phylogenetic trees of artifacts and cultures indicate archaeologists often mixed elements of Darwinian variational evolutionary change with elements of Midas-touch-like transformational change. Today there is minimal discussion of graph theory or graph grammar in both introductory archaeology textbooks and advanced texts, and elements of the two theories of evolution are often mixed. Culture has changed, and despite archaeology’s unique access to the totality of humankind’s cultural past, there is minimal discussion on graph theory, construction, and decipherment in the archaeological literature.
