Differences In Management Theory and Practice: Are Authors and Journals Contributin Factors?

The management literature offers evidence that thtere are differences in the way in which academicians and practitioners view the practice of management. It further suggests that those differences may, in part, be explained through the process by which management concepts are communicated to them, i.e. as a result of the way in which academic and practitioner oriented journals convey management concepts. This study examines journals with regard to their treatment of seleted concepts and finds that thtere are, in fact, no significant differences in their presentation. This suggested that earlier authors were incorrect in their assessment that differences in the journals service academic and practitioner marekts were, in part, responsible for differences between their readers\u27 views of management. It further suggests a possible alternate explanation

Digital Fandom: Mediation, Remediation, and Demediation of Fan Practices

It has been argued that fans make explicit what everyone else does implicitly. That is, fans interpret the world around them, communicate these meanings with others, and produce their own meanings based on those parts of the world that they like most. While all of us do this to various degrees, fans do so consciously, openly, and overtly. Also, fans actively appropriate the objects of culture in this process and rework them to further their interests in what has been referred to as a form of participatory culture. Fans do not merely consume culture; they creatively (re)produce culture, thus contributing directly to societal discourse. While some fan scholars have emphasized fan practices as a form of rebellion, others point out that this is a deeply affective process, even for anti-fans. For most, being a fan is ultimately a form of hedonic experience. Even though many fans devote a considerable amount of time, effort, and energy into their respective fandoms, it is usually a labor of love

Ambiguity and fandom: The (meaningless) consumption and production of popular culture

The purpose of this paper is to interrogate the concept of meaning and the meaning making process in consumer behavior. While the study of the consumption focuses increasingly on how consumers create meaning in a marketing dominated world, it views this process as relatively unproblematic. This paper challenges that perspective and argues that this process is inherently ambiguous

“What are you looking at, ya hockey puck?!”: Anthropomorphizing brand relationships in the Toy Story trilogy

What makes the Toy Story movies remarkable, at least from an academic perspective, is that they highlight not only the relationship between consumers and their brands, but also and perhaps more importantly the relationships among brands themselves. While it is tempting to think of brands as primarily consumer phenomena, brands do not exist in isolation or simply in relationships with humans, but are part of complex relationships with other brands. In fact, one could argue that it is this brand-to-brand relational context (or ‘brand network’), rather than the human-to-brand context, that gives brands (and ultimately humans) their meaning, personality and agency. We explore these brand networks through an analysis of anthropomorphism in the Toy Story movies

Thigh-length compression stockings and DVT after stroke

Controversy exists as to whether neoadjuvant chemotherapy improves survival in patients with invasive bladder cancer, despite randomised controlled trials of more than 3000 patients. We undertook a systematic review and meta-analysis to assess the effect of such treatment on survival in patients with this disease

Azithromycin in patients admitted to hospital with COVID-19 (RECOVERY): a randomised, controlled, open-label, platform trial

Background Azithromycin has been proposed as a treatment for COVID-19 on the basis of its immunomodulatory actions. We aimed to evaluate the safety and efficacy of azithromycin in patients admitted to hospital with COVID-19. Methods In this randomised, controlled, open-label, adaptive platform trial (Randomised Evaluation of COVID-19 Therapy [RECOVERY]), several possible treatments were compared with usual care in patients admitted to hospital with COVID-19 in the UK. The trial is underway at 176 hospitals in the UK. Eligible and consenting patients were randomly allocated to either usual standard of care alone or usual standard of care plus azithromycin 500 mg once per day by mouth or intravenously for 10 days or until discharge (or allocation to one of the other RECOVERY treatment groups). Patients were assigned via web-based simple (unstratified) randomisation with allocation concealment and were twice as likely to be randomly assigned to usual care than to any of the active treatment groups. Participants and local study staff were not masked to the allocated treatment, but all others involved in the trial were masked to the outcome data during the trial. The primary outcome was 28-day all-cause mortality, assessed in the intention-to-treat population. The trial is registered with ISRCTN, 50189673, and ClinicalTrials.gov, NCT04381936. Findings Between April 7 and Nov 27, 2020, of 16 442 patients enrolled in the RECOVERY trial, 9433 (57%) were eligible and 7763 were included in the assessment of azithromycin. The mean age of these study participants was 65·3 years (SD 15·7) and approximately a third were women (2944 [38%] of 7763). 2582 patients were randomly allocated to receive azithromycin and 5181 patients were randomly allocated to usual care alone. Overall, 561 (22%) patients allocated to azithromycin and 1162 (22%) patients allocated to usual care died within 28 days (rate ratio 0·97, 95% CI 0·87–1·07; p=0·50). No significant difference was seen in duration of hospital stay (median 10 days [IQR 5 to >28] vs 11 days [5 to >28]) or the proportion of patients discharged from hospital alive within 28 days (rate ratio 1·04, 95% CI 0·98–1·10; p=0·19). Among those not on invasive mechanical ventilation at baseline, no significant difference was seen in the proportion meeting the composite endpoint of invasive mechanical ventilation or death (risk ratio 0·95, 95% CI 0·87–1·03; p=0·24). Interpretation In patients admitted to hospital with COVID-19, azithromycin did not improve survival or other prespecified clinical outcomes. Azithromycin use in patients admitted to hospital with COVID-19 should be restricted to patients in whom there is a clear antimicrobial indication.

Heteromeric Solute Carriers: Function, Structure, Pathology and Pharmacology

Solute carriers form one of three major superfamilies of membrane transporters in humans, and include uniporters, exchangers and symporters. Following several decades of molecular characterisation, multiple solute carriers that form obligatory heteromers with unrelated subunits are emerging as a distinctive principle of membrane transporter assembly. Here we comprehensively review experimentally established heteromeric solute carriers: SLC3-SLC7 amino acid exchangers, SLC16 monocarboxylate/H+ symporters and basigin/embigin, SLC4A1 (AE1) and glycophorin A exchanger, SLC51 heteromer Ost α-Ost β uniporter, and SLC6 heteromeric symporters. The review covers the history of the heteromer discovery, transporter physiology, structure, disease associations and pharmacology - all with a focus on the heteromeric assembly. The cellular locations, requirements for complex formation, and the functional role of dimerization are extensively detailed, including analysis of the first complete heteromer structures, the SLC7-SLC3 family transporters LAT1-4F2hc, b0,+AT-rBAT and the SLC6 family heteromer B0AT1-ACE2. We present a systematic analysis of the structural and functional aspects of heteromeric solute carriers and conclude with common principles of their functional roles and structural architecture

Coronal Heating as Determined by the Solar Flare Frequency Distribution Obtained by Aggregating Case Studies

Flare frequency distributions represent a key approach to addressing one of the largest problems in solar and stellar physics: determining the mechanism that counter-intuitively heats coronae to temperatures that are orders of magnitude hotter than the corresponding photospheres. It is widely accepted that the magnetic field is responsible for the heating, but there are two competing mechanisms that could explain it: nanoflares or Alfv\'en waves. To date, neither can be directly observed. Nanoflares are, by definition, extremely small, but their aggregate energy release could represent a substantial heating mechanism, presuming they are sufficiently abundant. One way to test this presumption is via the flare frequency distribution, which describes how often flares of various energies occur. If the slope of the power law fitting the flare frequency distribution is above a critical threshold, $\alpha=2$ as established in prior literature, then there should be a sufficient abundance of nanoflares to explain coronal heating. We performed $>$600 case studies of solar flares, made possible by an unprecedented number of data analysts via three semesters of an undergraduate physics laboratory course. This allowed us to include two crucial, but nontrivial, analysis methods: pre-flare baseline subtraction and computation of the flare energy, which requires determining flare start and stop times. We aggregated the results of these analyses into a statistical study to determine that $\alpha = 1.63 \pm 0.03$. This is below the critical threshold, suggesting that Alfv\'en waves are an important driver of coronal heating.Comment: 1,002 authors, 14 pages, 4 figures, 3 tables, published by The Astrophysical Journal on 2023-05-09, volume 948, page 7
