Insights into how Vietnamese retailers utilize social media to facilitate knowledge creation through the process of value co-creation
Get PDFSocial media usage is a direct result of Internet connectivity and is gaining increased prominence in business-to-consumer (B2C), business-to-business (B2B), and consumer-to-business (C2B) relationship building, which is allowing marketers to devise and implement digital marketing strategies that are perceived as enhancing a customer’s well-being. Through the process of utilizing social media (SM) to share information with consumers, marketers are affording themselves with the concept of value co-creation and ensuring that the development of knowledge is given priority. To explain how this happens in an emerging economy, in-depth personal interviews were undertaken with the owners of five retail fashion companies in Vietnam. The findings indicate that fashion retail companies in Vietnam are deploying digital marketing strategies that deliver perceived enhanced value to consumers through the process of value co-creation. This highlights the advantage of using SM in relation to increasing retail staff’s ability to convert information into usable resources such as intelligence and knowledge. By achieving knowledge conversion, retail staff fulfill the role of ‘knowledge broker’ and ‘knowledge connector’, and identify how organizational intervention, such as new operating structures, can help to deliver perceived enhanced value to customers
Almost optimal exact distance oracles for planar graphs
Get PDFWe consider the problem of preprocessing a weighted directed planar graph in order to quickly answer exact distance queries. The main tension in this problem is between space S and query time Q, and since the mid-1990s all results had polynomial time-space tradeoffs, e.g., Q = ~ Θ(n/√ S) or Q = ~Θ(n5/2/S3/2).
In this article we show that there is no polynomial tradeoff between time and space and that it is possible to simultaneously achieve almost optimal space n1+o(1) and almost optimal query time no(1). More precisely, we achieve the following space-time tradeoffs:
n1+o(1) space and log2+o(1) n query time,
n log2+o(1) n space and no(1) query time,
n4/3+o(1) space and log1+o(1) n query time.
We reduce a distance query to a variety of point location problems in additively weighted Voronoi diagrams and develop new algorithms for the point location problem itself using several partially persistent dynamic tree data structures
Social economy in the classroom: The London Birkbeck Schools
Get PDFThe London Birkbeck Schools represent a hitherto largely unexplored episode in the history of British education. They embody the contradictory faces of mid nineteenth-century radical Liberalism and are of interest first, because they were determinedly secular and pioneered what was for their time a novel and progressive pedagogy. Second, they had an explicit social purpose. ‘Social economy’—the antithesis of the ‘political economy’ of the founders of the London Mechanics’ Institute in whose lecture theatre the first school was established by William Ellis in 1848—was a central element of the curriculum. The schools and their values were contested. Their curriculum was attacked by the Church for its godlessness. Their teaching methods, advanced for the times, were lampooned by Dickens for being little better than the rote learning they challenged. Following the 1870 Elementary Education Act some collapsed or were incorporated in Board schools, but others went ‘up market’ in competition with them. Only one school building remains nearly intact today, reflecting in its architecture some of the most progressive elements of Ellis’ philosophy, but London streets and roads bearing Birkbeck’s name mark the locations of schools long gone and the curriculum issues are rehearsed in present-day debates
Moving from responsibility learning inaction to ‘responsibility learning-in-action’: a student-educator collective writing on the ‘unnoticed’ in the hidden curriculum at business schools
Get PDFWe are a student-educator writing collective that have come together outside the formal classroom to experiment with ‘writing differently’, imbued with a desire to enact collective resistance against ‘unnoticed’ and intentionally hidden aspects of the business school curriculum that condone, normalize, and reproduce social injustice and inequalities. As students and educator located in the Department of Organizational Psychology at a UK-based business school, we see our non-traditional writing and inquiry through collective writing as a form of resistance against hegemonic scientific norms of knowledge production that dominate our discipline. We evoked Freire’s problem-posing education through a collective enactment of ‘responsibility learning-in-action’ by participating in regular ‘writing as resistance’ sessions, where we wrote around our lived experiences of the ‘unnoticed’ and intentionally hidden curriculum and responsibility learning in the same virtual space and time and then read aloud to one another. Our coming together through this practice (re)claims relationality and solidarity in the student-educator relationship, which is in itself a contribution to the topic of the intersections between responsibility learning and the hidden curriculum at business schools
Recognition of facial expressions in autism: effects of face masks and alexithymia
Get PDFIt is often assumed that the recognition of facial expressions is impaired in autism. However,
recent evidence suggests that reports of expression recognition difficulties in autistic
participants may be attributable to co-occurring alexithymia – a trait associated with
difficulties interpreting interoceptive and emotional states – not autism per se. Due to
problems fixating on the eye-region, autistic individuals may be more reliant on information
from the mouth region when judging facial expressions. As such, it may be easier to detect
expression recognition deficits attributable to autism, not alexithymia, when participants are
forced to base expression judgements on the eye-region alone. To test this possibility, we
compared the ability of autistic participants (with and without high levels of alexithymia) and
non-autistic controls to categorize facial expressions i) when the whole face was visible, and
ii) when the lower portion of the face was covered with a surgical mask. High-alexithymic
autistic participants showed clear evidence of expression recognition difficulties: they
correctly categorised fewer expressions than non-autistic controls. In contrast, lowalexithymic autistic participants were unimpaired relative to non-autistic controls. The same
pattern of results was seen when judging masked and unmasked expression stimuli. In sum,
we find no evidence for an expression recognition deficit attributable to autism, in the
absence of high levels of co-occurring alexithymia, either when participants judge whole-face
stimuli or just the eye-region. These findings underscore the influence of co-occurring
alexithymia on expression recognition in autism
Introduction
Get PDFThis introductory chapter begins by taking stock of significant strands in the post-emancipation nineteenth-century Catholic history of Britain and Ireland, using the Crimean or Eastern War (1854‒6) to illustrate the interplay between questions of religious and national identity, separation, and integration for the peoples of Britain and Ireland. It then outlines the themes and structures of the volume. Lastly, it addresses the developing historiography of nineteenth-century Catholicism, highlighting national trajectories and shifting preoccupations; referencing major historians and their contributions; and pinpointing the unevenness of research across these two islands and four nations. It identifies the gaps in the scholarship and concludes by positing the need for engagement with new methodological approaches
Proactive suppression can be applied to multiple salient distractors in visual search
Get PDFThere is a growing body of research demonstrating that the capture of attention by a single salient distractor can be prevented via proactive suppression. In real-world contexts, there are often several distracting events that compete for attention, but it is entirely unknown whether multiple objects can be suppressed concurrently. We used behavioural and electrophysiological measures to investigate the existence and time course of multiple-item suppression. We employed search displays that contained either one or two uniquely coloured distractors that differed in their salience (S+ and S-), or no such distractors. Search performance improved with the number of salient distractors, indicating that the suppression of multiple items reduced effective display set size. This was also the case when target colour was no longer fully predictable, ruling out an alternative explanation in terms of attentional guidance by target templates. In an experiment where S+ and S- always appeared together in the same display, the PD component (a marker of proactive suppression) was triggered exclusively by the more salient distractor (S+), indicative of single-item suppression. However, when displays with one or both salient distractors were intermixed, a reliable PD component was also triggered by S-, even when it was accompanied by S+ in the same display. These results show that multiple concurrent salient signals can be proactively inhibited. They demonstrate that signal suppression processes can be adaptively employed to counteract visual distraction at different locations, in order to facilitate the attentional selection of relevant objects in crowded visual environments
Victorian beauty: 1945-1955
Get PDFThis article examines the reworking of Victorian beauty in the visual culture of post-war Britain. Although the work of post-war modernisation and reconstruction was regarded as a symbolic break with the nineteenth-century past, the Victorian age continued to haunt the nation in the years following the end of the war, generating its own distinctive fascination and beauty. Focussing on an historical melodrama, Pink String and Sealing Wax (UK; dir. Robert Hamer, 1945), the article examines the narrative and its star, Googie Withers, in order to examine the role, meaning and appeal of Victorianism and Victorian beauty in the post-war years
Towards a context-specific approach to understanding lawyers’ wellbeing: a synthesis review and future research agenda
Get PDFLegal sector organisations face mounting pressure to protect and promote lawyers’ wellbeing. However, knowledge is fragmented hindering research and practice development. Our review investigated current conceptual understanding and empirical evidence of contextual influences. We systematically mapped the global scholarly and grey literature published since 1970, reviewing 145 relevant publications. Lawyers’ wellbeing is conceptualised primarily as ill-being, despite wellbeing’s positive facets. Empirical consideration of work context is mostly absent, though we deduce a focus on large commercial law firm practice and public service/legal aid. Our explanatory synthesis is abductive, coalescing Bourdieu’s (1977) concepts of field and habitus with Hobfoll’s (1989) conservation of resources theory to explain how context influences lawyers’ wellbeing via distinct resource losses. We urge theoretical development to elucidate the role of context and theory-driven research on the cumulative effects of resource loss and gain. Recommendations for practice include a renewed focus on job design and line management upskilling
Designing a system to chart the development of the UK museum sector: an iterative approach
Get PDFPurpose: This paper presents our methodology for designing a system providing comprehensive data about the UK's museums and enabling research into the history, status and long-term development of the entire sector.
Design/methodology/approach: We have devised and applied an iterative methodology in order to deliver a knowledge base, web application, and website through which these and related resources are publicly accessed, allowing incorporation of the requirements of user stakeholders drawn from across the UK museum sector.
Findings: Our methodology has enabled the elicitation of usage scenarios, research questions, and feedback from a broad range of user stakeholders, allowing the system to be successfully delivered within the time and staffing constraints of a single publicly-funded research project. Feedback received from external evaluators and users of the system has been overwhelmingly positive.
Originality: The system includes the only comprehensive dataset of the UK's museums and is enabling new research by museum studies scholars and museum professionals. Our methodology can inform other projects aiming to create specialist knowledge resources involving a wide range of user stakeholders, particularly within constrained time and staffing resources
