Back to C19th business as usual: a surprise?
We explain how Marx’s theory of the determination of the value of commodities by labour-time leads Marx to predict recurrent crisis, moments of self-defeat, will inevitably occur in capitalism through a tendency for the profit rate to fall in labour-time terms as the economy grows. We then explore how Marx thought in the C19th that at the end of booms surplus capital pushes up speculation in fictitious capital (shares, futures etc). By surplus capital Marx means capital/profit that firms do not want to productively invest due to deteriorating profitability in labour-time terms. The fictitious capital bubble is not an accidental random bubble, but is rooted in the tendential behaviour of the productive economy. The bubble must inevitably burst and crisis result, appearing to be purely a financial crisis. We record how Grossmann repeats Marx’s argument in 1929, predicting a huge crisis for the US. We then model the concept of surplus capital. Our model shows how inflation may distort surface appearances, but does not stop the underlying situation in labour-time terms from manifesting on the surface through the return on investing in fictitious capital rising in booms eventually above the return from productive investment
Fielding Design, Design Fielding : Learning, Leading & Organising in New Territories
A framing question; What does (meaningful) collaboration look like in action? led to the search for and identification of a polycontext, a site where advanced collaborative activity is intelligible. This research aims to explore how the epistemic foundations of learning and design theory can adapt to collaborative approaches to organizing, learning and leadership as the macro-economic transition of digital transformation proceeds. Through embedded ethnographic engagement within a learning organization facilitating group-oriented, design-led collaborative learning experiences, a case study investigates multiple sites within a global organizational network whose distinctive methodology and culture provides a setting emblematic of frontier digital economic activity. The organization’s activity generates environments which notionally act as boundary sites where negotiation of epistemic difference is necessitated, consequently distinctive forms of expertise in brokerage and perspective-taking arise to support dynamic coordination, presenting a distinct take on group-oriented learning. Comprising interacting investigation of communities of facilitators and learning designers tasked to equip learners with distinctive forms of integrative expertise, with the objective of forming individuals adept at rapid orientation to contingent circumstances achieved by collaborative organizing. In parallel, investigating narratives of an organization’s formation led to grounded theory about how collaborative activity is enabled by shared reframing practices. Consequently, the organization anticipates and reshapes the field it operates within, the research discusses scalar effects of learning communities on industry work practices. The inquiry interrogates design-led learning and expertise formation apt for transformative activity within and beyond the digital economy. Exploring how methodological innovations within collaborative learning organizations are enacted and scaled, primary perspectives on design-led, group-oriented learning are evaluated alongside relevant secondary theoretic perspectives on collaborative organizing, learning and leading. The study synthesizes contributions that point to expansions of existing learning paradigms and anticipates how collaborative learning by design intervenes with the schematic assumptions at work in individuals, communities and fields. Observational insight, systematic analysis and theoretical evaluation are applied to problematize assumptions underlying social theory to anticipate generational expansions to the design methods field which responds to inadequacies in planning and organizing approaches applied by design. The research attempts to habituate understanding from outside design methods to better equip an explanatory understanding of contemporary design-led learning and expertise formation occurring in modern professional structures, especially in the creative industries. Together, the research investigates how learners navigate challenges of organizing, learning and leading into unseen territories
The Unmaking of Marx’s Capital: Heinrich’s Attempt to Eliminate Marx’s Crisis Theory
Michael Heinrich’s recent Monthly Review article claims that the law of the tendential fall in the rate of profit (LTFRP) was not proved by Marx and cannot be proved. Heinrich also argues that Marx had doubts about the law and that, for this and other reasons, his theory of capitalist economic crisis was only provisional and more or less in continual flux.
This response shows that Heinrich’s elementary misunderstanding of the law––his belief that it is meant to predict what must inevitably happen rather than to explain what does happen––is the source of his charge that it is unproved. It then shows that a simple misreading of Marx’s text lies at the basis of Heinrich’s claim that the simplest version of the LTFRP, “the law as such,” is a failure. Marx’s argument that increases in the rate of surplus-value cannot “cancel” the fall in the rate of profit is then defended against Heinrich’s attempt to refute it. Finally, the paper presents evidence that Marx was indeed convinced that the LTFRP is correct and that he regarded the crisis theory of volume 3 of Capital as finished in a theoretical sense

Burden of 30-Day Readmissions After Percutaneous Coronary Intervention in 833,344 Patients in the United States:Predictors, Causes, and Cost: Insights From the Nationwide Readmission Database
Objectives
This study aimed to examine the 30-day unplanned readmissions rate, predictors of readmission, causes of readmissions, and clinical impact of readmissions after percutaneous coronary intervention (PCI).
Background
Unplanned rehospitalizations following PCI carry significant burden to both patients and the local health care economy and are increasingly considered as an indicator of quality of care.
Methods
Patients undergoing PCI between 2013 and 2014 in the U.S. Nationwide Readmission Database were included. Incidence, predictors, causes, and cost of 30-day unplanned readmissions were determined.
Results
A total of 833,344 patients with PCI were included, of whom 77,982 (9.3%) had an unplanned readmission within 30 days. Length of stay for the index PCI was greater (4.7 vs. 3.9 days) and mean total hospital cost (37,524) was higher for patients who were readmitted compared with those not readmitted. The factors strongly independently associated with readmissions were index hospitalization discharge against medical advice (odds ratio [OR]: 1.91; 95% confidence interval [CI]: 1.65 to 2.22), transfer to short-term hospital for inpatient care (OR: 1.62; 95% CI: 1.38 to 1.90), discharge to care home (OR: 1.57; 95% CI: 1.51 to 1.64), and chronic kidney disease (OR: 1.50; 95% CI: 1.44 to 1.55). Charlson Comorbidity Index score (OR: 1.28; 95% CI: 1.27 to 1.29) and number of comorbidities (OR: 1.18; 95% CI: 1.17 to 1.18) were independently associated with unplanned readmission. The majority of readmissions were due to noncardiac causes (56.1%).
Conclusions
Thirty-day readmissions after PCI are relatively common and relate to baseline comorbidities and place of discharge. More than one-half of the readmissions were due to noncardiac causes
Dynamically Driven Evolution of the Interstellar Medium in M51
Massive star formation occurs in giant molecular clouds (GMCs); an understanding of the evolution of GMCs is a prerequisite to develop theories of star formation and galaxy evolution. We report the highest-fidelity observations of the grand-design spiral galaxy M51 in carbon monoxide (CO) emission, revealing the evolution of GMCs vis-a-vis the large-scale galactic structure and dynamics. The most massive GMCs (giant molecular associations (GMAs)) are first assembled and then broken up as the gas flow through the spiral arms. The GMAs and their H_2 molecules are not fully dissociated into atomic gas as predicted in stellar feedback scenarios, but are fragmented into smaller GMCs upon leaving the spiral arms. The remnants of GMAs are detected as the chains of GMCs that emerge from the spiral arms into interarm regions. The kinematic shear within the spiral arms is sufficient to unbind the GMAs against self-gravity. We conclude that the evolution of GMCs is driven by large-scale galactic dynamics—their coagulation into GMAs is due to spiral arm streaming motions upon entering the arms, followed by fragmentation due to shear as they leave the arms on the downstream side. In M51, the majority of the gas remains molecular from arm entry through the interarm region and into the next spiral arm passage
You are what you eat? Vegetarianism, health and identity
This paper examines the views of ‘health vegetarians’ through a qualitative study of an online vegetarian message board. The researcher participated in discussions on the board, gathered responses to questions from 33 participants, and conducted follow-up e-mail interviews with 18 of these participants. Respondents were predominantly from the United States, Canada and the UK. Seventy per cent were female, and ages ranged from 14 to 53 years, with a median of 26 years. These data are interrogated within a theoretical framework that asks, ‘what can a vegetarian body do?’ and explores the physical, psychic, social and conceptual relations of participants. This provides insights into the identities of participants, and how diet and identity interact. It is concluded that vegetarianism is both a diet and a bodily practice with consequences for identity formation and stabilisation
Dynamically Driven Evolution of the Interstellar Medium in M51
We report the highest-fidelity observations of the spiral galaxy M51 in CO
emission, revealing the evolution of giant molecular clouds (GMCs) vis-a-vis
the large-scale galactic structure and dynamics. The most massive GMCs
(so-called GMAs) are first assembled and then broken up as the gas flow through
the spiral arms. The GMAs and their H2 molecules are not fully dissociated into
atomic gas as predicted in stellar feedback scenarios, but are fragmented into
smaller GMCs upon leaving the spiral arms. The remnants of GMAs are detected as
the chains of GMCs that emerge from the spiral arms into interarm regions. The
kinematic shear within the spiral arms is sufficient to unbind the GMAs against
self-gravity. We conclude that the evolution of GMCs is driven by large-scale
galactic dynamics --their coagulation into GMAs is due to spiral arm streaming
motions upon entering the arms, followed by fragmentation due to shear as they
leave the arms on the downstream side. In M51, the majority of the gas remains
molecular from arm entry through the inter-arm region and into the next spiral
arm passage.Comment: 6 pages, including 3 figures. Accepted, ApJ
End-of-season influenza vaccine effectiveness in adults and children, United Kingdom, 2016/17
Introduction The United Kingdom is in the fourth season of introducing a universal childhood influenza vaccine programme. The 2016/17 season saw early influenza A(H3N2) virus circulation with care home outbreaks and increased excess mortality particularly in those 65 years or older. Virus characterisation data indicated emergence of genetic clusters within the A(H3N2) 3C.2a group which the 2016/17 vaccine strain belonged to. Methods: The test-negative case-control (TNCC) design was used to estimate vaccine effectiveness (VE) against laboratory confirmed influenza in primary care. Results: Adjusted end-of-season vaccine effectiveness (aVE) estimates were 39.8% (95% confidence interval (CI): 23.1 to 52.8) against all influenza and 40.6% (95% CI: 19.0 to 56.3) in 18-64-year-olds, but no significant aVE in ≥ 65-year-olds. aVE was 65.8% (95% CI: 30.3 to 83.2) for 2-17-year-olds receiving quadrivalent live attenuated influenza vaccine. Discussion: The findings continue to provide support for the ongoing roll-out of the paediatric vaccine programme, with a need for ongoing evaluation. The importance of effective interventions to protect the ≥ 65-year-olds remains
The Complexity of Transferring Remote Monitoring and Virtual Care Technology Between Countries: Lessons From an International Workshop
International deployment of remote monitoring and virtual care (RMVC) technologies would efficiently harness their positive impact on outcomes. Since Canada and the United Kingdom have similar populations, health care systems, and digital health landscapes, transferring digital health innovations between them should be relatively straightforward. Yet examples of successful attempts are scarce. In a workshop, we identified 6 differences that may complicate RMVC transfer between Canada and the United Kingdom and provided recommendations for addressing them. These key differences include (1) minority groups, (2) physical geography, (3) clinical pathways, (4) value propositions, (5) governmental priorities and support for digital innovation, and (6) regulatory pathways. We detail 4 broad recommendations to plan for sustainability, including the need to formally consider how highlighted country-specific recommendations may impact RMVC and contingency planning to overcome challenges; the need to map which pathways are available as an innovator to support cross-country transfer; the need to report on and apply learnings from regulatory barriers and facilitators so that everyone may benefit; and the need to explore existing guidance to successfully transfer digital health solutions while developing further guidance (eg, extending the nonadoption, abandonment, scale-up, spread, sustainability framework for cross-country transfer). Finally, we present an ecosystem readiness checklist. Considering these recommendations will contribute to successful international deployment and an increased positive impact of RMVC technologies. Future directions should consider characterizing additional complexities associated with global transfer
