<p>It may be considered that architecture does not as a discipline, acknowledge the changes a building will go through after construction completion. Therefore, weathering of materials occurs without direction forcing a building to degrade over time rather than mature. We may accept that materials have a given lifespan and that it is simply a question of time before that material is no longer suitable for its original use. However, the impermanence of materials through weathering need not be considered a negative element throughout the life of a building. It may give us the impression that we can grasp the effects of time in a tangible way through its visual expressions, reminding us of our own place in the cycle of time. This thesis was design led by firstly producing material experiments, and going on site to understand the conditions of weathering on materials. This lead to a number of questions – firstly, may architecture direct its own visual expression of time through embracing the inevitable process of weathering within its materials and site? Can these actualizations of time documenting the events of a buildings life promote the build up of personal memory between the user and the architecture they experience? These questions were tested through the design of temporary research accommodation units located at Te Raekaihau Point on the south coast of Wellington. Being an extremely harsh environment, the full force of a weathered trace could be illustrated. Through design, the idea of architecture as an evolving image was explored. The contrasting material time frames of concrete and wood were understood in their relation to one another and how one may act as a framework for the other. Concrete surfaces expressed positive and negative detail, directing the weather to enhance certain patterns over time. The organic nature of timber was interpreted throughout the site with varied levels of exposure. Original traces of weather on site were used to understand future interpretations. These traces influenced material placement, orientation and gave an understanding of the processes that will affect architecture in time. Accepting that no material is permanent, certain details explored the idea that one materials death may bring about the birth of another. Over time, a timber walkway connecting two areas of the site was designed to erode, revealing a concrete stairway hidden beneath. These design considerations lead to the conclusion that architecture must be considered over time, with careful consideration of the natural forces that will affect its development. A site analysis does not occur in one visit, it must be a more thorough process considering all aspects that affect materials in time and how best to work with these inevitable facts as opposed to against them. This will result in a building capable of capturing the actualisations of time promoting memory through the weathered trace.</p>

This chapter draws together the different strands of the book and it also resolves some outstanding issues, responding to some questions that were left unanswered. If autobiographical memory can involve memories of repeated or more generic events, can the field and observer perspective distinction be usefully applied in these cases? If autobiographical memory becomes semanticized over time, do observer perspectives involve more semantic information? What does remembering from-the-outside tell us about the nature of personal memory and the ways we have of getting outside of ourselves? This chapter answers questions such as these and summarizes the progress made by the book on understanding the nature of personal memory and the perspectival mind.

Over Time

Many outcome variables in developmental psychopathology research are highly stable over time. In conventional longitudinal data analytic approaches such as multiple regression, controlling for prior levels of the outcome variable often yields little (if any) reliable variance in the dependent variable for putative predictors to explain. Three strategies for coping with this problem are described. One involves focusing on developmental periods of transition, in which the outcome of interest may be less stable. A second is to give careful consideration to the amount of time allowed to elapse between waves of data collection. The third is to consider trait-state-occasion models that partition the outcome variable into two dimensions: one entirely stable and trait-like, the other less stable and subject to occasion-specific fluctuations.

Abstract Purpose This phase 1 open-label study evaluated the uptake kinetics of a novel theranostic PET radiopharmaceutical, 18F-rhPSMA-7.3, to optimise its use for imaging of prostate cancer. Methods Nine men, three with high-risk localised prostate cancer, three with treatment-naïve hormone-sensitive metastatic disease and three with castration-resistant metastatic disease, underwent dynamic 45-min PET scanning of a target area immediately post-injection of 300 MBq 18F-rhPSMA-7.3, followed by two whole-body PET/CT scans acquired from 60 and 90 min post-injection. Volumes of interest (VoIs) corresponding to prostate cancer lesions and reference tissues were recorded. Standardised uptake values (SUV) and lesion-to-reference ratios were calculated for 3 time frames: 35–45, 60–88 and 90–118 min. Net influx rates (Ki) were calculated using Patlak plots. Results Altogether, 44 lesions from the target area were identified. Optimal visual lesion detection started 60 min post-injection. The 18F-rhPSMA-7.3 signal from prostate cancer lesions increased over time, while reference tissue signals remained stable or decreased. The mean (SD) SUV (g/mL) at the 3 time frames were 8.4 (5.6), 10.1 (7) and 10.6 (7.5), respectively, for prostate lesions, 11.2 (4.3), 13 (4.8) and 14 (5.2) for lymph node metastases, and 4.6 (2.6), 5.7 (3.1) and 6.4 (3.5) for bone metastases. The mean (SD) lesion-to-reference ratio increases from the earliest to the 2 later time frames were 40% (10) and 59% (9), respectively, for the prostate, 65% (27) and 125% (47) for metastatic lymph nodes and 25% (19) and 32% (30) for bone lesions. Patlak plots from lesion VoIs signified almost irreversible uptake kinetics. Ki, SUV and lesion-to-reference ratio estimates showed good agreement. Conclusion 18F-rhPSMA-7.3 uptake in prostate cancer lesions was high. Lesion-to-background ratios increased over time, with optimal visual detection starting from 60 min post-injection. Thus, 18F-rhPSMA-7.3 emerges as a very promising PET radiopharmaceutical for diagnostic imaging of prostate cancer. Trial Registration NCT03995888 (24 June 2019).

Smart home, media and security systems intervene in the territory and boundaries of the home in a variety of ways. Among these are the capacity to watch the home from afar, and to record these observations over time, as well as using the home as a site of performance for those on the outside. In this paper, we map the meanings of the smart home and explore the tensions between security and visibility, adopting a cultural history and cultural analysis methodological approach. We make a contribution to the literature on the smart home, highlighting its connection to longer trajectories of media and cultural change, and to understanding the contemporary formations of technologised surveillance, with attention to practices that emerged in response to COVID-19. We focus on two aspects of our model of domestic smartification: Ludics (devices and systems for play or entertainment) and exteriorities (security and communication interfaces that remotely monitor and expose the home). We focus on these aspects relating them to ideas of haunting and the uncanny to explore the implications of making what was previously hidden visible and manipulable to others.

<p>Though researchers have examined the changes in the effects of product and service performance on customer satisfaction, the short time frames of most studies prevents deeper understanding of this relationship. This study collects information from pre-purchase to 15 years post-purchase from 11,056 potential and existing automobile customers in the Taiwan market. The data is analyzed by a regression model. Results reveal that the importance of both product and service performance change over long time and the long-term trends of product and service performance weights are non-linear. In addition, from pre-purchase to the second year post-purchase, service weight is higher than product weight, but after the third year, product weight exceeds service weight. Product and service weight on customer satisfaction over time exhibit curvilinear relationships. Therefore, which one of product or service a company should stress depends on the stage in the customer relationship.</p>

Recent studies of ethnic return migration have explained why (economic, political, and affective) and where (Asia and Europe) this phenomenon has primarily occurred. Of the research available, however, few have examined the manner in which framings and practices of gender impact the experiences of those who participate in these transnational sojourns. This study fills this void by examining how Korean American male ethnic return migrants understand and negotiate their masculine identities, as they “return” to their ancestral homeland of South Korea. Utilizing data from in-depth qualitative interviews, this study finds that respondents initially configure South Korea as a site where they may redeem their marginalized masculine identities by taking advantage of the surplus human capital afforded to them by their American status. Over time, however, “returnees” come to realize the fluidity of masculinity and its ideals, exposing the tenuousness of their claims to hegemonic masculinity even in South Korea.

Over Time

Aggression is often measured in the laboratory as an iterative ‘tit-for-tat’ sequence, in which two aggressors repeatedly inflict retaliatory harm upon each other. Aggression researchers typically quantify aggression by aggregating across participants’ aggressive behavior on such iterative encounters. However, this ‘aggregate approach’ cannot capture trajectories of aggression across the iterative encounters and needlessly eliminates rich information in the form of within-participant variability. As an alternative approach, I employed multilevel modeling to examine the slope of aggression across the 25-trial Taylor Aggression Paradigm (TAP) as a function of trait physical aggression and experimental provocation. Across two preregistered studies (combined N = 392), participants exhibited a modest decline in aggression. This decline reflected a reciprocal strategy, in which participants responded to an initially-provocative opponent with greater aggression that then decreased over time in order to matched their opponent’s declining levels of aggression. Against predictions, trait physical aggression and experimental provocation did not affect participants’ overall trajectories of aggression. Yet exploratory analyses suggested that participants’ tendency to reciprocate their opponent’s aggression with more aggression was greater at higher levels of trait physical aggression and attenuated among participants who had already been experimentally-provoked by their opponent. These findings (a) illustrate several advantages of a multilevel modeling approach as compared to an aggregate approach to iterative laboratory aggression paradigms, (b) demonstrate that the magnifying effects of trait aggression and experimental provocation on laboratory aggression are stable over brief time-frames, and (c) suggest that modeling the opponent’s behavior on such tasks reveals important information.

<p><b>Beneath the urban concrete of Wellington city lies a plethora of lost stories and voices, sometimes only accessible as fragments, which should contribute to the rich polyvocal narratives of a site. Recognition of these stories, even as fragments, enables local inhabitants and a wider audience to begin to understand the significance of place.</b></p> <p>Heritage stories transform from one time period to the next, creating overlapping layers of a site’s identity evolving over time. Each layer, while potentially representing its own unique story, contributes to the meta-narrative of a place. This design-led research investigation looks at the problem that arises when important stories of a place are lost when a site has transformed over time. The true story of a site is represented by the hidden layers from previous time periods, which have often fragmented or faded over time. This thesis proposes that lost layers, fragmented stories and faded voices can be reawakened through speculative architectural representation.</p> <p>Fragments of stories can be used to stimulate the imagination. The allegorical interpretation of fragments can be used to generate dreamscapes. Within a dreamscape, the multiple voices of multiple fragments can be heard together, even when they represent stories from different times. When dreamscapes are captured as allegorical drawing fragments, these multiple voices can be heard and retained even when they have partially faded away.</p> <p>This thesis explores how an allegorical architectural project, framed within techniques found in allegorical narrative fiction, can be successfully used as a critical method to help reawaken and unveil lost voices of place and generate speculative architectural outcomes that allow these voices to be heard. This design-led research proposes to reawaken lost voices of place through mapping the field of imagination, collage and the creation of dreamscapes, and allegorical drawing fragments.</p> <p>Italo Calvino’s Invisible Cities and Alan Lightman’s Einstein’s Dreams are examples of literary approaches to the allegorical interpretation of fragments. They are used in this investigation as literary provocateurs—allegorical generators to engage the imagination to reawaken lost voices as fragments and allow them to be heard in a collection—an archive of fragments. These two novels are effectively re-presenting place and time as dreamscapes. By enabling a series of fragmented stories to be heard as one, a richly polyvocal narrative is established that allows the reader to understand the significance of a place.</p> <p>Two neighbouring urban sites along the edge of Wellington Harbour have been selected for this investigation: the Taranaki Wharf Cut-out and the Kumutoto Stream Outlet. Both have unique tales to tell. The Kumutoto Stream Outlet is the site of the first culverted stream in Wellington. This entire stream has been silenced and has disappeared forever, yet it survives deep underground; this narrow outlet along the Wellington Harbour edge is the last vestigial remnant of its tale. The Taranaki Wharf Cut-out exposes the lost shoreline of Wellington before urban expansion. This shoreline has been silenced and has disappeared forever, and the cut-out provides the last visual connection to the lost landscape below. Fragments of the urban concrete have been removed from both these sites to reveal the lost remnants of the sites tales they once concealed. These sites are engaged as allegorical portals that invite a viewer below the surface of Wellington’s urban concrete to explore the lost layers of fragmented stories that lay hidden beneath. These sites are presented as ‘characters’ that narrate ‘stories’ of Wellington waterfront’s surrounding context and the transformation of the landscape over time.</p> <p>The original heritage conditions of a place often cannot be physically returned to their sites without disrupting the contemporary urban context. In this investigation, sites are not engaged as grounds for architectural intervention. Instead, they are provocateurs for how an allegorical architectural project can dig below the urban concrete and reawaken and unveil lost voices of a place. These voices are presented as a speculative archive of fragmented artefacts that invite viewers to witness, through these allegorical artefacts, an urban environment’s rich litany of heritage stories that may have been permanently lost or displaced. These artefacts take the form of maps, collages and drawings, and they are designed to read both as individual artefacts and together as a collection within an archive, this bound codex of work—an Archive of Fragments of Time.</p> <p>This thesis asks:How can an allegorical architectural project be successfully used as a critical method to reawaken and unveil lost voices of a place, and generate speculative architectural outcomes that allow these voices to be heard?</p>

This goal of this chapter is to provide a design and development roadmap for the adaptation of traditional classroom activities into engaging iPad-based digital learning activities. Reporting on an ongoing longitudinal case study, the chapter provides an overview of rationale and design considerations of the authentic iPad learning design implementation project, and the outcomes and improvements made over time. The iPad activities described provide further details of the approach taken and adaptations made. Since implementing iPad activities into this higher education environment several terms ago, the lecturer reports significantly higher levels of student engagement. Additionally, students report that the classroom activities in the post-graduate marketing course are authentic, transferrable, and are more engaging due the use of the iPad-based activities.
