An Investigation of Indeterminate Structures Stressed Beyond the Proportional Limit

In the structural field the methods of designing have been geared to the development of materials...In a more current appraisal we see steel and concrete being updated still further. Pre-stressed concrete is a common sight in present day construction work and, to a lesser extent, the educated eye sees rigid frames designed to ultimate load criteria. Here again are cases where materials are studied and found to possess characteristics that are adaptable to advance methods. The key to all such improvements is still the realization and utilization of material properties

The sequential and moral (dis)order of public disputes: how speakers resist, partition and do being reasonable in talk-in-interaction

This thesis puts forward a strong argument for why more up-to-date interactional research is needed into disputes and why disciplines, methodological approaches and theories should come second to the phenomenon. This thesis investigates how people behave in disputes. Disputes are a ubiquitous part of everyday life – we know a great a deal about disputes in particular contexts, how people disagree, and how disputes can be resolved. However, little is known about the specific interactional features of public disputes. Public disputes are disputes which occur in a public place where there are onlookers – for instance, on public transport, on the radio, or during protests, for instance. These are activities which regularly occur throughout everyday life as our opinions, beliefs, views, identity and/or knowledge etc. clash. This research examines actual, naturally-occurring disputes between strangers in public. The focus is on the ways that people challenge those contestations, resist those challenges, and manage their relationship with their co-disputant.The data comprises a corpus of over 100 recordings of disputes between members of the public. The data were collected, transcribed, and analysed within an ethnomethodological framework using a combination of conversation analysis, membership categorisation analysis, and discursive psychology in order to demonstrate how the phenomenon is handled sequentially and rhetorically. This combination of approaches centres the phenomena rather than focusing on the application of methods. The three analytic chapters are organised around different features of disputes and address the overall structural organisation of a dispute.The first analytic chapter inspects enticing sequences, which is a way that a challenge can be produced that reverses the logic of the other’s argument. This chapter (Chapter 3) builds on previous research, and lays the groundwork for the other chapters, to show the sequential placement and forms of resistance to challenges. This illustrates resistance as a solution to the practical problem of being trapped in a challenge with nowhere to go. The second analytic chapter investigates how people do partitioning, that is, how they exploit the boundaries of their situated identity, or category (i.e. from radio caller to father). This chapter (Chapter 4) shows how people reconfigure their relationship with their co-disputant(s), and how certain actions (i.e. requests, directives, instructions) trade on the relevance of this new relationship. The final analytic chapter examines how people work to appear ‘reasonable’ in a dispute. People seek to win a dispute and one way of accomplishing that is to be the ‘reasonable’ person relative to the other’s unreasonable behaviour. In this chapter (Chapter 5), I unpack this to show how, through meta-talk, people present their behaviour as reasonable, or the other’s behaviour as unreasonable, to produce a purportedly-rational argument. I reveal that whilst participants rarely express reasonableness, they do respond to transgressions of conversational norms (i.e. turn-taking, sequence). Consequently, this accomplishes a turn-at-talk and a chance to control the direction of the dispute.The thesis presents a state-of-the-art examination of disputative interactions and contributes significantly to our understanding of the structural organisation of disputes and how people behave in public places. Throughout the course of the thesis, I establish frameworks for future research that combine ethnomethodological approaches, deals with the ‘messiness’ and difficulty of public video-recordings, and develops an understanding of what a dispute actually is.</div

What Does “Resistance” Actually Look Like? The Respecification of Resistance as an Interactional Accomplishment

In this introductory article to the special issue on Resistance in Talk-in-Interaction, we review the vast body of research that has respecified resistance by investigating it as and when it occurs in real-life encounters. Using methodological approaches such as ethnomethodology, conversation analysis, and discursive psychology, studies of resistance “in the wild” treat social interaction as a sequentially organized, joint enterprise. As a result, resistance emerges as the alternative to cooperation and therefore, on each occasion, resistant actions are designed to deal with the sequential and moral accountabilities that arise from the specifics of the situation. By documenting the wide array of linguistic, prosodic, sequential, and embodied resources that individuals use to resist the requirements set by interlocutors’ prior turns, this article provides the first comprehensive overview of existing research on resistance as an interactional accomplishment.</p

"Facebook's about to know, Karen":mobilising social media to sanction public conduct

This paper explores the social action of sanctioning an interlocutor’s conduct in public spaces through social media. Using membership categorisation analysis (Hester and Eglin 1997), we examine how, in offline face-to-face disputes filmed by one party, interactants deploy the name ‘Karen’ to sanction someone and threaten the transposition of the recording onto social media to impose accountability to the public at large. Our findings show how sanctioning through categorising an individual as a ‘Karen’ is interactionally achieved through framing conduct as entitled or otherwise problematic, distinguishing in-situ production of ‘Karen’ from a delivery that is perceptually unavailable to an interlocutor. We explore how social media functions as a resource to shape the ongoing encounter by orienting to the camera, and thus the online audience, as an external authority

Reporting mobile device-mediated text to manage action and agency in co-present conversation

The paper considers the role of agency in human interaction with mobile devices. We use multimodal conversation analysis to trace how mobile screen content is reproduced as locally relevant for updating information for co-present interlocutors. While informing-centered actions supported by mobile devices may sometimes have the character of an agentic intrusion into the local interaction, we show that the organization of device-accessed information and its meaningfulness is nonetheless positioned in relation to how device-supported updates are animated into social action by human participants. This research contributes to understanding how device-related content is sequentially incorporated into face-to-face interaction

Speaking out against everyday sexism: Gender and epistemics in accusations of “mansplaining”

In everyday interaction, subtle manifestations of sexism often pass unacknowledged and become internalised and thus perceived as "natural" conduct. The introduction of new vocabularies for referring to previously unnamed sexist conduct would presumably enable individuals to start problematising hitherto unchallengeable sexism (Calder-Dawe, 2015). In this paper, we investigate whether and how these vocabularies empower people to speak out against sexism. We focus on the use of the term “mansplaining” which, although coined over 10 years ago, remains controversial and contested. Using Conversation Analysis and Membership Categorisation Analysis, this paper excavates the interactional methods individuals use to formulate, in vivo, some prior spate of talk as mansplaining. In doing so, speakers necessarily reformulate a co-participant’s social action to highlight its sexist nature. Accusations of mansplaining are accomplished by invoking gender (and other) categories and their associated rights to knowledge. In reconstructing another’s conduct as mansplaining, speakers display their understanding of what mansplaining is (and could be) for the purpose at hand. Thus, the paper contributes to the well-established body of interactional research on manifestations of sexism by documenting how the normativity of epistemic rights is mobilised as a resource for bringing off accusations of mansplaining

External Workloads Vary by Position and Game Result in US-based Professional Soccer Players

International Journal of Exercise Science 16(6): 688-699, 2023. Professional soccer is a physically demanding sport that requires players to be highly trained. Advances using GPS allow the tracking of external workloads for individual players in practice and competition, however, there is a lack of evidence on how these measures impact match results. Therefore, we analyzed external workloads by player position and determined if they vary depending on the result of competitive matches. External workloads were analyzed in professional soccer players (n = 25) across 28 competitive games. One-way ANOVA determined if workloads varied by position (striker – ST, wide midfielder - WM, central midfielder – CM, wide defender - WD, central defender – CD) or across games won (n = 8), lost (n = 13) or tied (n = 7). Repeated-measures ANOVA assessed differences in workloads specific to each position in each of the result categories. Statistical significance was set at p \u3c 0.05. Across all games, more high-speed and very-high speed running was done by ST and WD compared to CD (p \u3c 0.001) and CM (p \u3c 0.001 - 0.02). Whole-team data showed no differences in any external workload variable with respect to match result (p \u3e 0.05), however, in games won ST did more very high-speed running than in losing games (p = 0.03) and defending players did more high and very high-speed running in games tied vs. those won or lost (p \u3c 0.05). Whole-team external workloads do not vary depending on the match result; however, high speed running may be a differentiating factor at the positional level. Coaches should consider position-specific analysis when examining player workloads

Engineering semiconductor nanowires for photodetection: From visible to terahertz

III-V semiconductor nanowires combine the properties of III-V materials with the unique advantages of the nanowire geometry, allowing efficient room temperature photodetection across a wide range of photon energies, from a few eV down to meV. For example, due to their nanoscale size, these show great promise as sub-wavelength terahertz (THz) detectors for near-field imaging or detecting elements within a highly integrated on-chip THz spectrometer. We discuss recent advances in engineering a number of sensitive photonic devices based on III-V nanowires, including InAs nanowires with tunable photoresponse, THz polarisers and THz detectors.The authors gratefully acknowledge financial support from the European Research Council (ERC Starting Grant ACrossWire), the Engineering and Physical Sciences Research Council (UK), the Australian Research Council, and the Australian National Fabrication Facility (ANFF).

A genome-wide association study identifies protein quantitative trait loci (pQTLs)

There is considerable evidence that human genetic variation influences gene expression. Genome-wide studies have revealed that mRNA levels are associated with genetic variation in or close to the gene coding for those mRNA transcripts - cis effects, and elsewhere in the genome - trans effects. The role of genetic variation in determining protein levels has not been systematically assessed. Using a genome-wide association approach we show that common genetic variation influences levels of clinically relevant proteins in human serum and plasma. We evaluated the role of 496,032 polymorphisms on levels of 42 proteins measured in 1200 fasting individuals from the population based InCHIANTI study. Proteins included insulin, several interleukins, adipokines, chemokines, and liver function markers that are implicated in many common diseases including metabolic, inflammatory, and infectious conditions. We identified eight Cis effects, including variants in or near the IL6R (p = 1.8×10 -57), CCL4L1 (p = 3.9×10-21), IL18 (p = 6.8×10-13), LPA (p = 4.4×10-10), GGT1 (p = 1.5×10-7), SHBG (p = 3.1×10-7), CRP (p = 6.4×10-6) and IL1RN (p = 7.3×10-6) genes, all associated with their respective protein products with effect sizes ranging from 0.19 to 0.69 standard deviations per allele. Mechanisms implicated include altered rates of cleavage of bound to unbound soluble receptor (IL6R), altered secretion rates of different sized proteins (LPA), variation in gene copy number (CCL4L1) and altered transcription (GGT1). We identified one novel trans effect that was an association between ABO blood group and tumour necrosis factor alpha (TNF-alpha) levels (p = 6.8×10-40), but this finding was not present when TNF-alpha was measured using a different assay , or in a second study, suggesting an assay-specific association. Our results show that protein levels share some of the features of the genetics of gene expression. These include the presence of strong genetic effects in cis locations. The identification of protein quantitative trait loci (pQTLs) may be a powerful complementary method of improving our understanding of disease pathways. © 2008 Melzer et al
