The Resilience and Adaptability of an Innovative Ecosystem of Creative Entrepreneurs during Crisis Times: Baltic Creative CIC – A Case Study

This empirical chapter explores the case of Baltic Creative Community Interest Company, a creative hub that enabled and demonstrated intrapersonal entrepreneurial capitals (Pret, Shaw and Drakopoulou Dodd 2016) to adapt quickly and develop novel offers for their tenants during an unprecedented period of crisis and change in the wider ecosystem. Baltic Creative CIC is a community owned property development company established to regenerate an underused post-industrial area in Liverpool and support the Creative and Digital community. Over the past decade, they have become a creative hub where small, unique micro businesses thrive alongside more established enterprises. Using an organisational ethnographic approach, we highlight the complexity in the conversion of entrepreneurial capitals and how this has demonstrated resilience and adaptability in the CIC during the global coronavirus pandemic in the 2020s. During the first coronavirus lockdown in 2020, they responded swiftly to tenants by providing a wide variety of business support initiatives. Regular communications on sector specific Covid-19 operational guidance and a support programme to help tenants apply for Liverpool City Council Small Business Support grants. The establishment of this hub for creative entrepreneurs prior to the recent disruption proved invaluable. Although they were severely tested, emerging behaviours were identified, agility, adaptability, and resilience during periods of crisis. This chapter offers key insights for scholars and those leading on creative hubs and cluster policy development and economic initiatives for creative sector support regionally, nationally, and internationally

Working towards fostering programming acceptance in the everyday lives of older and adult people with low levels of formal education:a qualitative case study

With the ever-increasing development of digital technologies, understanding their acceptance or rejection is important. A great deal of research, led by the Technology Acceptance Model (TAM), shows that technology acceptance is a hot and complex topic. Much of it has been quantitative and operationalized within mandatory—workplace/organizational—contexts, where instrumental aspects of technology use (e.g., efficiency and productivity) play a central role. In this chapter, we report on a qualitative case study—based on 3 in-person learning courses—of factors that can help us foster programming acceptance in the everyday lives of older and adult people with low levels of formal education. We discuss the relative relevance of technology acceptance constructs, showing that perceived ease-of-use is much less relevant than perceived usefulness, because all participants had to find the fit of programming in their lives. We show that two social aspects—the figure of the course instructor and the group—were key to introduce programming and encourage decision-making. We also discuss some methodological issues, such as the difficulties in asking validated items of TAM (e.g. “I have the knowledge necessary to use the system”) to our participants

Ventilatory muscle strength, diaphragm thickness and pulmonary function in world-class powerlifters.

Resistance training activates the ventilatory muscles providing a stimulus similar to ventilatory muscle training. We examined the effects of elite powerlifting training upon ventilatory muscle strength, pulmonary function and diaphragm thickness in world-class powerlifters (POWER) and a control group (CON) with no history of endurance or resistance training, matched for age, height and body mass

An essential function for the ATR-Activation-Domain (AAD) of TopBP1 in mouse development and cellular senescence

ATR activation is dependent on temporal and spatial interactions with partner proteins. In the budding yeast model, three proteins – Dpb11TopBP1, Ddc1Rad9 and Dna2 - all interact with and activate Mec1ATR. Each contains an ATR activation domain (ADD) that interacts directly with the Mec1ATR:Ddc2ATRIP complex. Any of the Dpb11TopBP1, Ddc1Rad9 or Dna2 ADDs is sufficient to activate Mec1ATR in vitro. All three can also independently activate Mec1ATR in vivo: the checkpoint is lost only when all three AADs are absent. In metazoans, only TopBP1 has been identified as a direct ATR activator. Depletion-replacement approaches suggest the TopBP1-AAD is both sufficient and necessary for ATR activation. The physiological function of the TopBP1 AAD is, however, unknown. We created a knock-in point mutation (W1147R) that ablates mouse TopBP1-AAD function. TopBP1-W1147R is early embryonic lethal. To analyse TopBP1-W1147R cellular function in vivo, we silenced the wild type TopBP1 allele in heterozygous MEFs. AAD inactivation impaired cell proliferation, promoted premature senescence and compromised Chk1 signalling following UV irradiation. We also show enforced TopBP1 dimerization promotes ATR-dependent Chk1 phosphorylation. Our data suggest that, unlike the yeast models, the TopBP1-AAD is the major activator of ATR, sustaining cell proliferation and embryonic development

Mycotic aneurysm of the femoral artery complicating Staphylococcus aureus bacteremia: a case report

INTRODUCTION: Staphylococcus aureus is the major cause of bacteremia, with the potential for some complications, namely mycotic aneurysms, defined as irreversible dilatation of an artery due to destruction of the vessel wall by infection. CASE PRESENTATION: The authors present the case of a 52 year-old-Caucasian male, admitted with Staphylococcus aureus bacteremia and mycotic aneurysm of the right superficial femoral artery, associated with advanced atherosclerotic process. CONCLUSION: Mycotic aneurysms are rare, and a high index of suspicion is needed, because appropriate treatment will certainly affect the outcome, as they are associated with high morbidity and mortality

The coordination of cell growth during fission yeast mating requires Ras1-GTP hydrolysis

The spatial and temporal control of polarity is fundamental to the survival of all organisms. Cells define their polarity using highly conserved mechanisms that frequently rely upon the action of small GTPases, such as Ras and Cdc42. Schizosaccharomyces pombe is an ideal system with which to study the control of cell polarity since it grows from defined tips using Cdc42-mediated actin remodeling. Here we have investigated the importance of Ras1-GTPase activity for the coordination of polarized cell growth during fission yeast mating. Following pheromone stimulation, Ras1 regulates both a MAPK cascade and the activity of Cdc42 to enable uni-directional cell growth towards a potential mating partner. Like all GTPases, when bound to GTP, Ras1 adopts an active conformation returning to an inactive state upon GTP-hydrolysis, a process accelerated through interaction with negative regulators such as GAPs. Here we show that, at low levels of pheromone stimulation, loss of negative regulation of Ras1 increases signal transduction via the MAPK cascade. However, at the higher concentrations observed during mating, hyperactive Ras1 mutations promote cell death. We demonstrate that these cells die due to their failure to coordinate active Cdc42 into a single growth zone resulting in disorganized actin deposition and unsustainable elongation from multiple tips. These results provide a striking demonstration that the deactivation stage of Ras signaling is fundamentally important in modulating cell polarity

Matched sizes of activating and inhibitory receptor/ligand pairs are required for optimal signal integration by human Natural Killer cells

It has been suggested that receptor-ligand complexes segregate or co-localise within immune synapses according to their size, and this is important for receptor signaling. Here, we set out to test the importance of receptor-ligand complex dimensions for immune surveillance of target cells by human Natural Killer (NK) cells. NK cell activation is regulated by integrating signals from activating receptors, such as NKG2D, and inhibitory receptors, such as KIR2DL1. Elongating the NKG2D ligand MICA reduced its ability to trigger NK cell activation. Conversely, elongation of KIR2DL1 ligand HLA-C reduced its ability to inhibit NK cells. Whereas normal-sized HLA-C was most effective at inhibiting activation by normal-length MICA, only elongated HLA-C could inhibit activation by elongated MICA. Moreover, HLA-C and MICA that were matched in size co-localised, whereas HLA-C and MICA that were different in size were segregated. These results demonstrate that receptor-ligand dimensions are important in NK cell recognition, and suggest that optimal integration of activating and inhibitory receptor signals requires the receptor-ligand complexes to have similar dimensions

Changes in take-home aerated soft drink purchases in urban India after the implementation of Goods and Services Tax (GST): An interrupted time series analysis.

OBJECTIVES: Taxes on sugar-sweetened beverages (SSB) are increasingly being implemented as public health interventions to limit the consumption of sugar and reduce associated health risks. In July 2017, India imposed a new tax rate on aerated (carbonated) drinks as part of the Goods and Services Tax (GST) reform. This study investigates the post-GST changes in the purchase of aerated drinks in urban India. METHODS: An interrupted time series analysis was conducted on state-level monthly take-home purchases of aerated drinks in urban India from January 2013 to June 2018. We assessed changes in the year-on-year growth rate (i.e. percentage change) in aerated drink purchases with controls for contextual variables. RESULTS: We found no evidence of a reduction in state-level monthly take-home aerated drink purchases in urban India following the implementation of GST. Further analysis showed that the year-on-year growth rate in aerated drink purchases increased slightly (0.1 percentage point per month, 95%CI = 0.018, 0.181) after the implementation of GST; however, this trend was temporary and decreased over time (0.008 percentage point per month, 95%CI = -0.015, -0.001). CONCLUSIONS: In India, a country currently with low aerated drink consumption, the implementation of GST was not associated with a reduction in aerated drink purchase in urban settings. Due to the lack of accurate and sufficiently detailed price data, it is not possible to say whether this finding is driven by prices not changing sufficiently. Furthermore, the impact of GST reform on industry practice (reformulation, marketing) and individual behaviour choices (substitution) is unknown and warrants further investigation to understand how such taxes could be implemented to deliver public health benefits
