In this paper, we examine when members of underrepresented groups choose to support each other, using the context funding female founders via donation-based crowdfunding. Building on theories choice homophily, develop concept activist in which basis attraction between two individuals is not merely similarity them, but rather perceptions shared structural barriers stemming from a common social identity based group membership. We differentiate homophily (“interpersonal homophily”), as well...
Background. Evidence supports peroneal nerve functional electrical stimulation (FES) as an effective alternative to ankle-foot orthoses (AFO) for treatment of foot drop poststroke, but few randomized controlled comparisons exist. Objective. To compare changes in gait and quality life (QoL) between FES AFO individuals with poststroke. Methods. In a multicenter trial (ClinicalTrials.gov #NCT01087957) unblinded outcome assessments, 495 Medicare-eligible at least 6 months poststroke wore or...
Jason Greenberg, Roberto M. Fernandez Sociological Science, May 18, 2016 DOI 10.15195/v3.a14 Abstract Whether and how social ties create value has inspired substantial research in organizational theory, sociology, economics.
Background. Evidence supports peroneal nerve functional electrical stimulation (FES) as an effective alternative to ankle foot orthoses (AFO) for treatment of drop poststroke, but few long-term, randomized controlled comparisons exist. Objective. Compare changes in gait quality and function between FES AFOs individuals with poststroke over a 12-month period. Methods. Follow-up analysis unblinded trial (ClinicalTrials.gov #NCT01087957) conducted at 30 rehabilitation centers comparing 6...
Female founders seek and receive less startup capital than male entrepreneurs. One reason for this disparity is a lack of female representation among funders startups, potential solution to increase the proportion women in decision-making roles. Both problem implicitly rely on homophily – that will support other given chance. However, clarity over when how influences individual choices makes it uncertain better actually advantageous. Using data from crowdfunding, we empirically examine...
The strength of weak ties is among the most important theories in social sciences. One paradoxical element theory has been widely understood and valued—that connect disparate regions structure. Less appreciated, however, arguably more implication that someone only weakly connected to another would provide value beyond which provided by recipient’s (ego’s) strong ties. Once this feature associated empirical literatures acknowledged, interests resource provider (alter) demand consideration. To...
Social scientists have long considered what mechanisms underlie repeated exchange. Three garnered the majority of this attention: formal contracts, relational and relationally embedded social ties. Although each mechanism has its virtues, all three exhibit a common limitation: an inability to fully explain continuation stability intertemporal exchange between individuals organizations in face change. Drawing on extensive quantitative data approximately 450,000 microfinance loans made by...

We suggest that a systematic socio-cognitive approach to “competitive sensemaking” has been absent from theory and research on competitive strategy. define sensemaking as the social cognitive processes underlie how firms detect, define, conceptualize their relationships with other firms. Competitive is subset of more general process strategic sensemaking, which “making plausible sense” broad array stimuli circumstances characterize complex market situations. Using value-based view value...
FUNCTIONAL magnetic resonance imaging (fMRI) and transcranial stimulation (TMS) are noninvasive techniques recently used to investigate cortical motor physiology. However, these modalities measure different phenomena, in studies of human control they have given inconsistent results. We developed a reproducible technique which co-registers TMS fMRI, using frameless method. In four normal subjects, the map fMRI activation were present on primary cortex contralateral target hand, with some...
Background Chronic musculoskeletal pain is common in patients with Alzheimer’s disease (AD), and there growing awareness that chronic has an impact on the progression of dementia. Yoga shown promise treating pain. However, attending in-person yoga can be difficult for AD patients. Objective To assess feasibility, acceptability preliminary efficacy online (teleyoga) protocol suitable pain, their caregivers. Methods Patients comorbid mild ( n = 15, 57-95 y/o; 73% Female) caregivers 50-75 67%...

Twelve controls 12 patients were studied. Hand output determined using transcranial magnetic stimulation. Motor-evoked potentials recorded simultaneouslyfrom both hands. Functional abilities evaluated well-validated measures. Surface area, weighted surface center gravity calculated....
Collateral flow patterns are important risk factors for brain ischemia in the presence of internal carotid artery (ICA) stenosis or occlusion. Ophthalmic (OA) reversal, routinely studied by transcranial Doppler sonography, is an marker high-grade ICA The authors sought to define value assessing OA direction with color duplex ultrasonography (CDUS) setting significant disease.Of all patients having routine ultrasound neurosonology laboratory between July 1995 and November 2000, 152 had both...
A widespread scholarly and popular consensus suggests that new ventures perform better when launched by teams, rather than individuals. This view has become so pervasive many of the foremost investors rarely, if ever, fund startups founded a solo entrepreneur. Despite this belief in superiority teams startup process, little empirical evidence been used to examine key question. In paper, we implications founding alone versus as group using unique dataset crowdfunded companies together...
There is often considerable anxiety and conflicting advice concerning the benefits of presenting/being evaluated first. We thus investigate how expert evaluators vary in their evaluations entrepreneurial proposals based upon order which they are evaluated.

This enables us credibly...
Abstract Research Summary We investigate the extent to which increasing availability of ratings information has affected heterogeneity in firm performance and, if so, what market segments are responsible for these changes. A unique dataset was constructed with restricted‐access government data examine questions context New York City restaurant industry between 1994 and 2013. find that firms serving tourist expensive price point experienced sales discrepancies as a function rating...
In many facets of life, individuals make evaluations that they may update after consulting with others in their networks. But not all have the same positional opportunities for social interaction a given network or ability and desire to use those are available them. The configuration person’s can also alter how information is spread interpreted. To complicate matters further, scant research has considered positions networks valence content interact because difficulty (a) separating “player”...
INTELLECTUAL TRADITIONS IN THE LIFE SCIENCES. II. STEREOCOMPLEMENTARITY SCOTTF. GILBERT* andJASON P.

Cerebral vasoreactivity can be studied with transcranial Doppler (TCD) by monitoring CO2-induced middle cerebral artery (MCA) velocity changes. Expected MCA mean (Vm) changes due to in end-expiratory CO2 (EE-CO2) are established, but reactivity of common carotid (CCA) volume flow rate (VFR) has not been extensively reported. The authors assess the relationship between Vm, CCA VFR, and EE-CO2. Ten normal individuals without cerebrovascular disease diameters more than 3.0 mm were studied. VFR...
