The Best of Both Worlds: Partnering with the Community to Create the Guttman Center for Early Care and Education
The Guttman Center for Early Care and Education was established in the fall of 2016 at Bank Street College with the intention of providing quality professional development and support to Family Child Care Providers (early childhood educators running small private daycares out of their homes) in Brooklyn, New York. Completely free to all participants, the Center seeks to attract providers, regardless of age, education level or years of experience, who were interested in deepening their understanding of early childhood development. Through a deep touch community engagement strategy and utilization of Bank Street\u27s renowned Infancy Masters Program, early educators are encouraged to build relationships with and educate young children in their most crucial first three years of life
Tame, messy and wicked problems in risk management
Heathrow's Terminal Five presents a case study in risk management that shows the
importance of understanding and incorporating the behavioural and perception
aspects of risk. At the outset of the project, risk was conceived technically, its
management was sequentially driven and problems met with linear solutions. The
case study follows a change in perspective experienced by the Terminal Five project
teams alerting the project to important, but previously ignored, aspects of risk. This
change required different ways of conceiving problem, and the paper describes how
this can be done using a typology of: 'tame', 'wicked' and 'messy' problems. This
requires risk managers to identify project stakeholders and seek resolutions between
their varying perspectives, as much as deliver singular, optimal solutions. Typically,
because wicked and messy problems cannot be modelled, they have been ignored, so
undermining the ability of the project team to control the project effectively. This
case study shows how risk management can embrace behavioural and systems
complexity without undermining either clarity of information or control of project
processes

Unexpected patterns of global population structure in melon-headed whales Peponocephala electra
Foraging specialization, environmental barriers, and social structure have driven the development of strong genetic differentiation within many marine species, including most of the large dolphin species commonly referred to as ‘blackfish’ (subfamily Globicephalinae). We used mitochondrial sequence data (mtDNA) and genotypes from 14 nuclear microsatellite loci (nDNA) to examine patterns of genetic population structure in melon-headed whales Peponocephala electra (MHWs), poorly known members of the blackfish family for which genetic structuring is unknown. MHWs are globally distributed in tropical and subtropical waters, and have formed resident populations around oceanic islands. They frequently mass strand, suggesting strong social cohesion within groups. Based on these characteristics, we hypothesized that MHWs would exhibit strong regional genetic differentiation, similar to that observed in other members of the Globicephalinae subfamily. Instead we found only moderate differentiation (median mtDNA ΦST = 0.204, median nDNA FST = 0.012) among populations both within and between ocean basins. Our results suggest that populations of MHWs that are resident to oceanic islands maintain a higher level of genetic connectivity than is seen in most other blackfish. MHWs may be more behaviorally similar to delphinids from the Delphininae subfamily (particularly the spinner dolphin Stenella longirostris), which are known to form coastal and island-associated resident populations that maintain genetic connectivity either through occasional long-distance dispersal or gene flow with larger pelagic populations. Our results suggest that differences in social organization may drive different patterns of population structure in social odontocete
Analysis of hadronic transitions in Υ(3S) decays
This is the publisher's version, also available electronically from http://journals.aps.org/prd/abstract/10.1103/PhysRevD.49.40.Using the CLEO II detector, we have measured the branching fractions for Υ(3S)→ππΥ(1S), Υ(3S)→ππΥ(2S), and the cascade Υ(3S)→Υ(2S)+X, Υ(2S)→π+π−Υ(1S), analyzing the exclusive mode where the daughter Υ state decays to a e(+)e(−) or μ(+)μ(−) pair, as well as the inclusive π(+)π(−) transitions where the final Υ state decays into hadrons. Properties of the ππ system are analyzed. Searches for the cascade decay Υ(3S)→π+π−h(b), h(b)→γη(b) and Υ(3S)→π0h(b) were also performed
Search for color-suppressed B hadronic decay processes at the Υ(4S) resonance
This is the publisher's version, also available electronically from http://journals.aps.org/prd/abstract/10.1103/PhysRevD.57.5363.Using 3.1fb(-1) of data accumulated at the Υ(4S) by the CLEO-II detector, corresponding to 3.3×10(6) BB¯ pairs, we have searched for the color-suppressed B hadronic decay processes B(0)→D(0)(D*(0))X(0), where X(0) is a light neutral meson π(0), ρ(0(, η, η′ or ω. The D*(0) mesons are reconstructed in D*(0)→D(0)π(0) and the D(0) mesons in D(0)→K(-)π(+), K(-)π(+)π(0) and K(-)π(+)π(+)π(-) decay modes. No obvious signal is observed. We set 90% C.L. upper limits on these modes, varying from 1.2×10(-4) for B(0)→D(0)π(0) to 1.9×10(-3) for B(0)→D*(0)η′
Experimental tests of lepton universality in τ decay
This is the publisher's version, also available electronically from http://journals.aps.org/prd/abstract/10.1103/PhysRevD.55.2559.The branching fractions for τ→eνν(τ), μνν(τ), and hν(τ) are measured using data collected with the CLEO detector at the CESR e(+)e(-) collider: Be=0.1776±0.0006±0.0017, Bμ=0.1737±0.0008±0.0018, and B(h)=0.1152±0.0005±0.0012, where the first error is statistical, the second systematic, and h refers to either a charged π or K. Also measured is the τ mass, mτ=(1778.2±1.4) MeV. Lepton universality is affirmed by the relative branching fractions (B(μ)/B(e)=0.9777±0.0063±0.0087, B(h)/B(e)=0.6484±0.0041±0.0060) and the charged-current gauge coupling-constant ratios (g(μ)/g(e)=1.0026±0.0055, g(τ)/g(μ)=0.9990±0.0098). The τ mass result may be recast as a τ neutrino mass limit, m(ν)(τ)<60 MeV at 95% C.L
Measurements of the meson-photon transition form factors of light pseudoscalar mesons at large momentum transfer
This is the publisher's version, also available electronically from http://journals.aps.org/prd/abstract/10.1103/PhysRevD.57.33.Using the CLEO II detector, we have measured the differential cross sections for exclusive two-photon production of light pseudoscalar mesons π(0), η, and η′. From our measurements we have obtained the form factors associated with the electromagnetic transitions γ*γ⃗ meson. We have measured these form factors in the momentum transfer ranges from 1.5 to 9, 20, and 30GeV(2) for π(0), η, and η′, respectively, and have made comparisons to various theoretical predictions
