Trends in financial market concentration and their implications for market stability

The link between financial market concentration and stability is a topic of great interest to policymakers and other market participants. Are concentrated markets - those where a relatively small number of firms hold large market shares - inherently more prone to disruption? This article considers that question by drawing on academic studies as well as introducing new analysis. Like other researchers, the authors find an ambiguous relationship between concentration and instability when a large firm in a concentrated market fails. In a complementary review of concentration trends across a number of specific markets, the authors document that most U.S. wholesale credit and capital markets are only moderately concentrated, and that concentration trends are mixed - rising in some markets and falling in others. The article also identifies market characteristics that might lead to greater, or less, concern about the consequences of a large firm's exit. It argues that the ease of substitution by other firms in concentrated markets is a critical factor supporting market resiliency.Financial markets ; Capital market ; Theory of the firm

Concurrent Sessions: Dig Where You Stand: Infusing Local History and Culture into the Curriculum to Support the Success of Diverse Student Populations

This session introduces a model of curriculum design that positions the history and culture of the local community as central to students’ learning experiences. Presenters will highlight a unique partnership between Bunker Hill Community College and Boston’s Museum of African American History that engages incoming students in exploring local history, diverse cultures and their civic identities. Participants will gain an understanding of the impact of inclusive, place-based curricula on students’ successful transition to college as well as practice hands-on strategies for implementing such a program at their institution

Integrated metastate functional connectivity networks predict change in symptom severity in clinical high risk for psychosis

The ability to identify biomarkers of psychosis risk is essential in defining effective preventive measures to potentially circumvent the transition to psychosis. Using samples of people at clinical high risk for psychosis (CHR) and Healthy controls (HC) who were administered a task fMRI paradigm, we used a framework for labelling time windows of fMRI scans as ‘integrated’ FC networks to provide a granular representation of functional connectivity (FC). Periods of integration were defined using the ‘cartographic profile’ of time windows and k‐means clustering, and sub‐network discovery was carried out using Network Based Statistics (NBS). There were no network differences between CHR and HC groups. Within the CHR group, using integrated FC networks, we identified a sub‐network negatively associated with longitudinal changes in the severity of psychotic symptoms. This sub‐network comprised brain areas implicated in bottom‐up sensory processing and in integration with motor control, suggesting it may be related to the demands of the fMRI task. These data suggest that extracting integrated FC networks may be useful in the investigation of biomarkers of psychosis risk

Testing and characterization of the TESS CCDs

The Transiting Exoplanet Survey Satellite (TESS) is an Explorer-class mission dedicated to finding planets around bright, nearby stars so that more detailed follow-up studies can be done. TESS is due to launch in 2017 and careful characterization of the detectors will need to be completed on ground before then to ensure that the cameras will be within their photometric requirement of 60ppm/hr. TESS will fly MITLincoln Laboratories CCID-80s as the main scientific detector for its four cameras. They are 100μm deep depletion devices which have low dark current noise levels and can operate at low light levels at room temperature. They also each have a frame store region, which reduces smearing during readout and allows for near continuous integration. This paper describes the hardware and methodology that were developed for testing and characterizing individual CCID-80s. A dark system with no stimuli was used to measure the dark current. Fe 55 and Cd 109 X-ray sources were used to establish gain at low signal levels and its temperature dependence. An LED system that generates a programmable series of pulses was used in conjunction with an integrating sphere to measure pixel response non-uniformity (PRNU) and gain at higher signal levels. The same LED system was used with a pinhole system to evaluate the linearity and charge conservation capability of the CCID-80s.United States.

Negotiating Closed Doors and Constraining Deadlines: The Potential of Visual Ethnography to Effectually Explore Private and Public Spaces of Motherhood and Parenting

Pregnancy and motherhood are increasingly subjected to surveillance, by medical professionals, the media and the general public; and discourses of ideal parenting are propagated alongside an admonishment of the perceived ‘failing’ maternal subject. However, despite this scrutiny, the mundane activities of parenting are often impervious to ethnographic forms of inquiry. Challenges for ethnographic researchers include the restrictions of becoming immersed in the private space of the home where parenting occurs, and an institutional structure that discourages exploratory and long-term fieldwork. This paper draws on four studies, involving 34 participants, which explored their journeys into the space of parenthood and their everyday experiences. The studies all employed forms of visual ethnography including artefacts, photo-elicitation, timelines, collage and sandboxing. The paper argues that visual methodologies can enable access to unseen aspects of parenting, and engender forms of temporal extension, which can help researchers to disrupt the restrictions of tightly time bounded projects

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
