Paradox: Towards a Metatheory
No full textHistory reveals countless attempts by great minds to solve life’s paradoxes. But what if these attempts miss the point? What if paradox is life?
Contrary to the supposedly sublime linear logic that underpins our prevalent modes of theoretical and empirical enquiry, in this fascinating book, organizational anthropologist Tom Vine charts the pervasiveness of paradox across the academy: from arithmetic to zoology. In so doing, he reflects on the concept of paradox as a widespread existential ‘pattern’, a pattern which holds significant metatheoretical and pedagogical potential. Paradoxes, he argues, are not inconveniences or ‘fault lines in our common-sense world’ but are coded into our very existence. Paradoxes thus present their own vital logics that shape our lives: they thwart moral and ideological uniformity; they even out subjective experience between ‘the haves’ and ‘the have nots’; and they shed light on the opaque concepts of consciousness and agency.
This book will appeal to anybody with a curious mind, particularly scholars and students with an interest in one or more of the following: complexity theory, critical pedagogies, ethnography, nonlinear dynamics, organization theory, and systems theory
Special issue: ‘Lonely are the brave’
Get PDFThe Western has been seen as a key genre for understanding both the American national character and the particulars of Hollywood, but there are now very few contemporary studies of this once foundational genre. The articles in this Special Issue, coming out of the Lonely Are the Brave conference of 2021, aim to revisit the Western, and the post-war Western specifically, in order to revive scholarship surrounding these texts, to interrogate existing models of understanding the history of the genre, and to examine how the genre treats ideas connected to time and its passing as attached to the American west and its depictions on-screen
Joint interference cancellation and signal detection using latent space representations in VAE
No full textLand Mobile Radios (LMRs) are a two-way consumer radio communication system, popularly used for public safety operations. An unintentional strong far-out interfering signal causes the LMR receiver to be overloaded and reduces the gain of the weak desired signal. The conventional non-learning based methods to mitigate the effects of interference require prior knowledge of the interferer or additional filtering components at the RF front-end of the receiver. In this paper, we propose a novel data-driven unsupervised Deep Learning-based approach for joint interference detection, interference cancellation and signal detection of narrowband LMR signals that we refer to as DeepLMR. The DeepLMR uses a Variational Autoencoder (VAE)-based framework known as Recovery VAE (Re-VAE), with a Gumbel-Softmax distribution that encodes the input to a lower dimensional representation as the latent space representations. The latent space representations are sampled
from a categorical distribution and classified to the corresponding symbols of the transmitted signal. Experimental results with real-world signals distorted by a strong far-out interfering signal showed that our proposed DeepLMR architecture has bit error rate (BER) performance improvements as compared to the conventional frequency discriminator and other state-of-the-art Deep Learning-based architectures
Understanding legitimacy building in contexts through digital entrepreneurship
Get PDFPurpose
This paper, through empirical evidence, presents a framework for exploring how entrepreneurs navigate the challenges of building legitimacy in a digital context. In so doing, this paper goes beyond the seemingly forgone conclusion that legitimacy is important for the entrepreneur's success by focusing on the contextualised mechanisms through which digital legitimacy is built.
Design/methodology/approach
Empirical findings are drawn from semi-structured interviews conducted with 21 digital entrepreneurs in Nigeria, a leading example of the West African context and analysed using a phenomenological approach.
Findings
The paper shows how digital entrepreneurs in a non-Western context draw on an aspect of legitimation in the digital space, and in particular, highlights three mechanisms via which this takes place, namely: digital shielding, digital curating and digital networking. Presented via an inductive approach, the three mechanisms described in the paper provide a scaffold for thinking about and understanding entrepreneurial legitimacy within a contextual framework, which incorporates institutional, cultural and digital dimensions.
Originality/value
This paper contributes to the literature on digital entrepreneurship by empirically identifying and theoretically elaborating themes that are important for understanding how entrepreneurs navigate the challenges of digital entrepreneurship and build entrepreneurial legitimacy in complex contexts
Picking the length: investigating how bowling length influences batter decision-making in international men’s 50-over cricket
Get PDFIn this study, 19,587 balls bowled by fast bowlers across two One- Day International (ODI) cricket tournaments were analysed, with the aim of exploring the relationship between bowling lengths and foot-based batter decision-making. Initially, a Chi-Square test of independence was used to determine if bowling lengths were associated with the foot-based decision-making of batters. Subsequently, the relationship of specific foot-based strokes with different bowling lengths were further examined through a Logistic Regression. Post-Hoc analysis of standardised residuals from Chi- Square tests suggest an association between foot-based decision- making and dot balls (χ2(1) = 99.798, p < .001). Furthermore, Logistic Regression results reveal that all length zones except the half-tracker length show statistically significant association with front-foot and back-foot strokes. Respective coefficients of these length zones also show an organisation of specific strokes with front-foot stroke dominating lengths close to the batter (yorker, full-toss, half-volley and good length) and back-foot strokes dom- inating zones further away from the batter (back of a length and short length). The results confirm interdependence between batter- bowler performances and suggest that batters in ODI cricket prefer meetin

The ‘ethic of care’: a possible tool in the field when studying elites
Get PDFEdwards and Mauthner (2012, p. 14) describe research ethics as ‘the moral deliberation, choice and accountability on the part of the researchers throughout the research process’. As such, research ethical codes are designed to provide researchers with guidance on what is ‘morally right or wrong’ when undertaking empirical research (Barnes, 1979, p. 16, as cited in Heath, 2009, p. 23). These codes grew out of instances of a clear disregard for morals when conducting research – for example, during Nazi experiments in concentration camps – which led to the formalisation of such ideas as informed consent and voluntary participation (Mandal et al., 2011). Today, it is the accepted norm that all social science research with humans must adhere to conventions like informed consent, confidentiality and the protection of participants from physical or psychological harm (BERA, 2018). Indeed, adhering to and reflecting on conventional ethical principles is not only critical for gaining approval from university ethics committees, without which one often cannot conduct research, but also considered a hallmark of good quality research (Heath, 2009)
Interior archives: an experiment in autobiographical fiction
No full textThis chapter is an experiment in imaginative dialogue. It is co-authored but also calls upon 19th century authors Charlotte Perkins Gilman and Anna Atkins to act as spirit guides in the use of fiction to explore a relationship between the family photograph and autobiographical memory. In an extension of Roland Barthes’ biographeme, it discusses the idea that photographic, and photographed, objects can become nexuses that connect, stimulate, and radiate autobiographical memories. It champions imaginary involvement and an emotional response to the family photograph as a way of giving voice to the voiceless. The chapter is split into two interrelated voices. Voice 1 focuses on the methods and processes involved in creating fictional dialogues with photographic objects. Voice 2 creates a series of fictional dialogues with a collection of photographic images scattered randomly throughout the text. The reader is encouraged

The post-activation performance enhancement effect of a parallel back squat on male jumping and sprinting athletes
Get PDFBackground: Although the literature has described different ways and methodologies of producing chronic neuromuscular enhancements in athletes, less is known about warm-up activities aiming to optimize short-term performance. To address these gaps, investigations into post-activation performance enhancement (PAPE) effects are necessary. As such, this work aimed to analyse the PAPE effect of different parallel squat (PS) protocols with and without whole-body vibration (WBV) employing different volumes (low and high) and rest periods (of one and four minutes) on jumping performance. Methods: Seventeen elite sprinting and jumping male athletes participated in this study. The athletes completed one PAPE protocol on a weekly basis, according to the following conditions: PS with 80% one-repetition maximum (1RM) without vibration (NV-PS) and with WBV (WBV-PS). Each exercise was performed at a high and low volume, and after short or long recovery periods (of one and four minutes). A countermovement jump (CMJ) and drop jump (DJ) without an arm swing were executed before and after each PAPE protocol. Results: Higher CMJ and DJ performances after WBV-PS exercises were found (effect size [ES] = 1.065–1.319, large). Greater DJ results were observed after an NV-PS exercise with a high volume and four minutes of rest (37.78 ± 5.44 vs 39.09 ± 5.62; p = 0.011; ES = 0.692, medium). Time x condition effects (F = 25.239, p < 0.01, η^2= 0.03) were observed, revealing higher CMJ values after a WBV-PS in comparison to baseline conditions, as well as higher DJ values after NV-PS and WBV-PS in comparison to baseline conditions. Conclusions: The findings indicate that these types of PAPE protocols in elite male athletes and WBV-PS PAPE protocols in particular can enhance CMJ and DJ performance, while the NV-PS (using a high volume and four minutes of rest) resulted in improvements for the DJ. No other improvements were reported using NV-PS combinations
