Reconciling the Volcker Rule with the Dodd-Frank Act’s Objectives: How to Best Combat Systemic Risk
This Note examines the Dodd-Frank Act’s ban on proprietary trading and on banks sponsoring hedge funds and private equity funds, known as the Volcker Rule. This Rule has been a point of contention since the Act was passed in 2010. Some argue that the ban is either a detriment to bond market liquidity or is unnecessary because a tenuous nexus exists between proprietary trading and true causes of the 2008 financial crisis. Proponents cite the role of proprietary trading in the crisis and the inherent risk that banks accept when engaging in such trading. The controversy surrounding the Volcker Rule has led individuals in politics and finance to discuss whether to amend, or even repeal, the Rule. This Note explores arguments for and against the Volcker Rule and ultimately offers recommendations to amend the Rule while maintaining its (and Dodd-Frank’s) venerable goal of curbing systemic risk. First, this Note begins with a discussion of the causes of the financial crisis and systemic risk before explaining the Rule’s provisions. This background provides the groundwork for the ongoing debate about the Volcker Rule and whether there should be a change in the language of the Rule. Proponents and opponents have clashed on multiple issues, such as whether proprietary trading played a significant role in the financial crisis and whether it actually reduces systemic risk. Understanding arguments on both sides is crucial to assess whether and how the Volcker Rule should be amended in light of systemic risk. This Note concludes that neither outright repeal of the Rule nor leaving it fully intact are appropriate. Rather, this Note offers recommendations to amend it in a way that balances banks’ desires to engage in profitable trading with the global interest in curbing systemic risk in the financial system
Women’s experiences of wearing therapeutic footwear in three European countries
Background: Therapeutic footwear is recommended for those people with severe foot problems associated with
rheumatoid arthritis (RA). However, it is known that many do not wear them. Although previous European studies
have recommended service and footwear design improvements, it is not known if services have improved or if this
footwear meets the personal needs of people with RA. As an earlier study found that this footwear has more
impact on women than males, this study explores women’s experiences of the process of being provided with it
and wearing it. No previous work has compared women’s experiences of this footwear in different countries,
therefore this study aimed to explore the potential differences between the UK, the Netherlands and Spain.
Method: Women with RA and experience of wearing therapeutic footwear were purposively recruited. Ten women
with RA were interviewed in each of the three countries. An interpretive phenomenological approach (IPA) was
adopted during data collection and analysis. Conversational style interviews were used to collect the data.
Results: Six themes were identified: feet being visibly different because of RA; the referring practitioners’ approach
to the patient; the dispensing practitioners’ approach to the patient; the footwear being visible as different to
others; footwear influencing social participation; and the women’s wishes for improved footwear services. Despite
their nationality, these women revealed that therapeutic footwear invokes emotions of sadness, shame and anger
and that it is often the final and symbolic marker of the effects of RA on self perception and their changed lives.
This results in severe restriction of important activities, particularly those involving social participation. However,
where a patient focussed approach was used, particularly by the practitioners in Spain and the Netherlands, the
acceptance of this footwear was much more evident and there was less wastage as a result of the footwear being
prescribed and then not worn. In the UK, the women were more likely to passively accept the footwear with the
only choice being to reject it once it had been provided. All the women were vocal about what would improve
their experiences and this centred on the consultation with both the referring practitioner and the practitioner that
provides the footwear.
Conclusion: This unique study, carried out in three countries has revealed emotive and personal accounts of what
it is like to have an item of clothing replaced with an ‘intervention’. The participant’s experience of their
consultations with practitioners has revealed the tension between the practitioners’ requirements and the women’s
‘social’ needs. Practitioners need greater understanding of the social and emotional consequences of using
therapeutic footwear as an intervention
Computer-Supported Collaborative Learning, Blogging Groups, and Interpretation in the Literature Classroom
Community college world literature students are often ill prepared to analyze and interpret passages of creative fiction because traditional, teacher-centric pedagogical approaches do not promote students’ literary interpretive authority. However, a method to fill the interpretation gap remains unclear. The purpose of this qualitative single case study was to explore the efficacy of using computer-supported collaborative learning (CSCL) blogging groups to promote students’ interpretive authority and critical thinking skills. Blending transactional reading theory, social constructivist theory, and transformative learning theory provided the conceptual framework for the study. Participants were 8 students and their instructor from a purposefully selected community college literature class in the Northeast United States that included group blogging as part of its approach to interpreting literature. Data sources were student journals, blog posts, student questionnaires, and an instructor questionnaire. Data analysis was an inductive coding process to discover emerging categories and themes. Results indicated that students felt more comfortable and capable of interpreting literary texts after engaging in a CSCL literary interpretation process, and the course instructor affirmed the perception that students gained authority in interpreting literary texts. Findings may be used by community college literature instructors to promote CSCL blogging activities as a student-centered pedagogical approach for literary interpretation
Influence of Kinematics on the Wear of a Total Ankle Replacement
Total ankle replacement (TAR) is an alternative to fusion, replacing the degenerated joint with a mechanical motion-preserving alternative. Minimal pre-clinical testing has been reported to date and existing wear testing standards lack definition. Ankle gait is complex, therefore the aim of this study was to investigate the effect on wear of a range of different ankle gait kinematic inputs. Five Zenith (Corin Group) TARs were tested in a modified knee simulator for twelve million cycles (Mc). Different combinations of IR rotation and AP displacement were applied every 2Mc to understand the effects of the individual kinematics. Wear was assessed gravimetrically every Mc and surface profilometry undertaken after each condition. With the initial unidirectional input with no AP displacement the wear rate measured 1.2±0.6 mm3/Mc. The addition of 11° rotation and 9 mm of AP displacement caused a statistically significant increase in the wear rate to 25.8±3.1 mm3/Mc. These inputs seen a significant decrease in the surface roughness at the tibial articulation. Following polishing three displacement values were tested; 0, 4 and 9 mm with no significant difference in wear rate ranging 11.8–15.2 mm3/Mc. TAR wear rates were shown to be highly dependent on the addition of internal/external rotation within the gait profile with multidirectional kinematics proving vital in the accurate wear testing of TARs. Prior to surface polishing wear rates were significantly higher but once in a steady state the AP displacement had no significant effect on the wear
Clinical Characteristics and Treatment Patterns of Children and Adults With IgA Nephropathy or IgA Vasculitis: Findings From the CureGN Study
Introduction:
The Cure Glomerulonephropathy Network (CureGN) is a 66-center longitudinal observational study of patients with biopsy-confirmed minimal change disease, focal segmental glomerulosclerosis, membranous nephropathy, or IgA nephropathy (IgAN), including IgA vasculitis (IgAV). This study describes the clinical characteristics and treatment patterns in the IgA cohort, including comparisons between IgAN versus IgAV and adult versus pediatric patients.
Methods:
Patients with a diagnostic kidney biopsy within 5 years of screening were eligible to join CureGN. This is a descriptive analysis of clinical and treatment data collected at the time of enrollment.
Results:
A total of 667 patients (506 IgAN, 161 IgAV) constitute the IgAN/IgAV cohort (382 adults, 285 children). At biopsy, those with IgAV were younger (13.0 years vs. 29.6 years, P < 0.001), more frequently white (89.7% vs. 78.9%, P = 0.003), had a higher estimated glomerular filtration rate (103.5 vs. 70.6 ml/min per 1.73 m2, P < 0.001), and lower serum albumin (3.4 vs. 3.8 g/dl, P < 0.001) than those with IgAN. Adult and pediatric individuals with IgAV were more likely than those with IgAN to have been treated with immunosuppressive therapy at or prior to enrollment (79.5% vs. 54.0%, P < 0.001).
Conclusion:
This report highlights clinical differences between IgAV and IgAN and between children and adults with these diagnoses. We identified differences in treatment with immunosuppressive therapies by disease type. This description of baseline characteristics will serve as a foundation for future CureGN studies
Searching for online information on the fit of children's footwear during the COVID‐19 pandemic: an analysis of Google Trends data
AbstractBackgroundSelecting footwear with appropriate fit in children is challenging due the changes with foot size and dimensions which occur throughout childhood. Access to appropriate footwear is important but recent challenges with the COVID‐19 pandemic resulted in closure of retail stores for prolonged periods where parents/carers could not physically purchase footwear for their children and the footwear industry suffered disruption to their supply chain, and falls in retail sales. Simultaneously increased use of social media platforms for health information seeking throughout the pandemic have been documented. This likely would have included parents/carers seeking information online to support footwear purchases for their children. The primary aim of this work was to explore how searches for online fitting information for children changed throughout the COVID‐19 pandemic lockdown periods. A secondary aim was to identify how searches were influenced by footwear style.MethodsWe employed Google Trends to obtain search engine traffic related to footwear fitting information for children. We collected data spanning the three years pre, during and post the main national lockdown for three eight‐week windows: (1) first eight weeks of the U.K. national lockdown; (2) the first eight weeks of the calendaryear; (3) the eight weeks leading up to children going back‐to‐school for the new academic year in the U.K. The search terms reflected parents/carers searching for footwear fit information relating to children and were grouped by style of footwear: children, infants, babies and toddlers as well as school shoes.ResultsWe identified increased searching for footwear fit information for children during the pandemic, which reduced following post pandemic in all except the searches which related to school shoes. We saw reductions in searching related to fit of school shoes as schools closed indefinitely and an increase in online searches with the pandemic. This was also maintained post‐pandemic despite shops reopening, suggesting that some of these changes in information reflect new consumer behaviours which may continue.ConclusionsIncreased searches for online resources regarding footwear fit highlights the importance of ensuring high quality accessible online information on footwear fit is available to support those buying footwear for their children
Consequences of HIV infection in the bone marrow niche
Dysregulation of the bone marrow niche resulting from the direct and indirect
effects of HIV infection contributes to haematological abnormalities observed in
HIV patients. The bone marrow niche is a complex, multicellular environment
which functions primarily in the maintenance of haematopoietic stem/
progenitor cells (HSPCs). These adult stem cells are responsible for replacing
blood and immune cells over the course of a lifetime. Cells of the bone marrow
niche support HSPCs and help to orchestrate the quiescence, self-renewal and
differentiation of HSPCs through chemical and molecular signals and cell-cell
interactions. This narrative review discusses the HIV-associated dysregulation of
the bone marrow niche, as well as the susceptibility of HSPCs to infection by HIV.The NRF-DAAD program, the University of Pretoria, the National Research Foundation, the Bill and Melinda Gates Foundation and the South African Medical Research Council.http://www.frontiersin.org/Immunologyam2024ImmunologySDG-03:Good heatlh and well-bein
Risk stratification for arrhythmic death in an emergency department cohort: a new method of nonlinear PD2i analysis of the ECG
Heart rate variability (HRV) reflects both cardiac autonomic function and risk of sudden arrhythmic death (AD). Indices of HRV based on linear stochastic models are independent risk factors for AD in postmyocardial infarction (MI) cohorts. Indices based on nonlinear deterministic models have a higher sensitivity and specificity for predicting AD in retrospective data. A new nonlinear deterministic model, the automated Point Correlation Dimension (PD2i), was prospectively evaluated for prediction of AD. Patients were enrolled (N = 918) in 6 emergency departments (EDs) upon presentation with chest pain and being determined to be at risk of acute MI (AMI) >7%. Brief digital ECGs (>1000 heartbeats, ∼15 min) were recorded and automated PD2i results obtained. Out-of-hospital AD was determined by modified Hinkle-Thaler criteria. All-cause mortality at 1 year was 6.2%, with 3.5% being ADs. Of the AD fatalities, 34% were without previous history of MI or diagnosis of AMI. The PD2i prediction of AD had sensitivity = 96%, specificity = 85%, negative predictive value = 99%, and relative risk >24.2 (p ≤ 0.001). HRV analysis by the time-dependent nonlinear PD2i algorithm can accurately predict risk of AD in an ED cohort and may have both life-saving and resource-saving implications for individual risk assessment
C3 glomerulopathy: consensus report
C3 glomerulopathy is a recently introduced pathological entity whose original definition was glomerular pathology characterized by C3 accumulation with absent or scanty immunoglobulin deposition. In August 2012, an invited group of experts (comprising the authors of this document) in renal pathology, nephrology, complement biology, and complement therapeutics met to discuss C3 glomerulopathy in the first C3 Glomerulopathy Meeting. The objectives were to reach a consensus on: the definition of C3 glomerulopathy, appropriate complement investigations that should be performed in these patients, and how complement therapeutics should be explored in the condition. This meeting report represents the current consensus view of the group.Kidney International advance online publication, 30 October 2013; doi:10.1038/ki.2013.377
