The business-social policy nexus: Corporate power and corporate inputs into social policy
Get PDFIt is increasingly impossible to understand and explain the shape and delivery of
contemporary social policy unless we consider the role of business. Several factors have been at
work here. First, many of the changes in social policy introduced since the 1970s have been in
response either to business demands or more general concerns about national competitiveness
and the needs of business. Second, globalisation has increased corporate power within states,
leading to transformations in social and fiscal policies. Third, business has been incorporated
into the management of many areas of the welfare state by governments keen to control
expenditure and introduce private sector values into services. Fourth, welfare services, from
hospitals to schools, have been increasingly opened up to private markets. Despite all this, the
issues of business influence and involvement in social policy has been neglected in the literature.
This article seeks to place corporate power and influence centre-stage by outlining and critically
reflecting on the place of business within contemporary welfare states, with a particular focus
on the UK. Business, it argues, is increasingly important to welfare outcomes and needs to be
taken into account more fully within the social policy literature
Amplitude analysis of D-0 -> K- pi(+) pi(+) pi(-)
No full textKolcu, Onur Buğra (Arel Author)Kolcu, Onur Buğra (Arel Author)We present an amplitude analysis of the decay D-0 -> K- pi(+)pi(+)pi(-) based on a data sample of 2.93 fb(-1) acquired by the BESIII detector at the psi(3770) resonance. With a nearly background free sample of about 16000 events, we investigate the substructure of the decay and determine the relative fractions and the phases among the different intermediate processes. Our amplitude model includes the two-body decays D-0 -> (K) over bar*(0)rho(0), D-0 -> K- a(1)(+) (1260) and D-0 -> K-1(-)(1270)pi(+), the three-body decays D-0 -> K-1(-)*(0)pi(+)pi(-) and D-0 -> K- pi(+)rho(0), as well as the four-body nonresonant decay D-0 -> K- pi(+)pi(+)pi(-). The dominant intermediate process is D-0 -> K(-)a(1)(+)(1260)accounting for a fit fraction of 54.6%.We present an amplitude analysis of the decay D-0 -> K- pi(+)pi(+)pi(-) based on a data sample of 2.93 fb(-1) acquired by the BESIII detector at the psi(3770) resonance.

Measurement of CP asymmetry in D-0 -> K- K+ and D-0 -> pi(-) pi(+) decays
Get PDFTime-integrated CP asymmetries in D 0 decays to the final states K - K + and π - π + are measured using proton-proton collisions corresponding to 3fb-1 of integrated luminosity collected at centre-of-mass energies of 7 TeV and 8 TeV. The D 0 mesons are produced in semileptonic b-hadron decays, where the charge of the accompanying muon is used to determine the initial flavour of the charm meson. The difference in CP asymmetries between the two final states is measured to be Δ ACP = ACP (K- K +) ACP (π- π+) = (+ 0.14 ± 0.16 (stat) ± 0.08 (syst)) %. A measurement of A CP (K - K +) is obtained assuming negligible CP violation in charm mixing and in Cabibbo-favoured D decays. It is found to be ACP (K- K+) = (- 0.06 ± 0.15 (stat) ± 0.10 (syst)) %, where the correlation coefficient between ΔA CP and A CP (K - K +) is ρ = 0.28. By combining these results, the CP asymmetry in the D 0 → π - π + channel is A CP (π - π +) = (-0.20 ± 0.19 (stat) ± 0.10 (syst))%. [Figure not available: see fulltext.] © 2014 The Author(s)
First observation of Λb0 → ςc (∗)++ D (∗)-K- decays
No full textThe four decays, Λb0→ςc(∗)++D(∗)-K-, are observed for the first time using proton-proton collision data collected with the LHCb detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 6 fb-1. By considering the Λb0→Λc+D¯0K- decay as reference channel, the following branching fraction ratios are measured to be B(Λb0→ςc++D-K-)B(Λb0→Λc+D¯0K-)=0.282±0.016±0.016±0.005, B(Λb0→ςc∗++D-K-)B(Λb0→ςc++D-K-)=0.460±0.052±0.028, B(Λb0→ςc++D∗-K-)B(Λb0→ςc++D-K-)=2.261±0.202±0.129±0.046, B(Λb0→ςc∗++D∗-K-)B(Λb0→ςc++D-K-)=0.896±0.137±0.066±0.018, where the first uncertainties are statistical, the second are systematic, and the third are due to uncertainties in the branching fractions of intermediate particle decays. These initial observations mark the beginning of pentaquark searches in these modes, with more datasets to become available following the LHCb upgrade. © 2024 CERN, for the LHCb Collaboration.

Study of the decays D-s(+ )-> (KSK+)-K-0 and (KLK+)-K-0
No full textKolcu, Onur Buğra (Arel Author)Using an e(+)e(-) annihilation data sample corresponding to an integrated luminosity of 3.19 fb(-1) and collected at a center-of-mass energy root s = 4.178 GeV with the BESIII detector, we measure the absolute branching fractions B(D-s(+) -> (KSK+)-K-0) = (1.425 +/- 0.038(stat). +/- 0.031(syst).)% and B(D-s(+) -> (KLK+)-K-0) = (1.485 +/- 0.039(stat). +/- 0.046(syst).)%. The branching fraction of D-s(+) -> (KSK+)-K-0 is compatible with the world average and that of D-s(+) -> (KLK+)-K-0 is measured for the first time. We present the first measurement of the K-S(0)-K-L(0) asymmetry in the decays D-s(+) -> (KS,LK+)-K-0, and R((Ds+KS,LK+)-K-0) = B(D-s(+) -> (KSK+)-K-0)-B(D-s(+) -> (KLK+)-K-0)/B(D-s(+) -> (KSK+)-K-0)+B(D-s(+) -> (KLK+)-K-0) = (-2.1 +/- 1.9(stat). +/- 1.6(syst).)%. In addition, we measure the direct CP asymmetries A(CP) (D-s(+/-) -> (KSK +/-)-K-0). (0.6 +/- 2.8(stat). +/- 0.6(syst).)% and A(CP)(D-s(+/-) -> (KLK +/-)-K-0 ) = (-1.1 +/- 2.6(stat). +/- 0.6(syst))
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
Get PDFThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
Depolarization and decreased surface expression of K+ channels contribute to NSAID-inhibition of intestinal restitution
No full textNon-steroidal anti-inflammatory drugs (NSAIDs) contribute to gastrointestinal ulcer formation by inhibiting epithelial cell migration and mucosal restitution; however, the drug-affected signaling pathways are poorly defined. We investigated whether NSAID inhibition of intestinal epithelial migration is associated with depletion of intracellular polyamines, depolarization of membrane potential (Em) and altered surface expression of K+ channels. Epithelial cell migration in response to the wounding of confluent IEC-6 and IEC-Cdx2 monolayers was reduced by indomethacin (100μM), phenylbutazone (100μM) and NS-398 (100μM) but not by SC-560 (1μM). NSAID-inhibition of intestinal cell migration was not associated with depletion of intracellular polyamines. Treatment of IEC-6 and IEC-Cdx2 cells with indomethacin, phenylbutazone and NS-398 induced significant depolarization of Em, whereas treatment with SC-560 had no effect on Em. The Em of IEC-Cdx2 cells was: −38.5±1.8mV under control conditions; −35.9±1.6mV after treatment with SC-560; −18.8±1.2mV after treatment with indomethacin; and −23.7±1.4mV after treatment with NS-398. Whereas SC-560 had no significant effects on the total cellular expression of Kv1.4 channel protein, indomethacin and NS-398 decreased not only the total cellular expression of Kv1.4, but also the cell surface expression of both Kv1.4 and Kv1.6 channel subunits in IEC-Cdx2. Both Kv1.4 and Kv1.6 channel proteins were immunoprecipitated by Kv1.4 antibody from IEC-Cdx2 lysates, indicating that these subunits co-assemble to form heteromeric Kv channels. These results suggest that NSAID inhibition of epithelial cell migration is independent of polyamine-depletion, and is associated with depolarization of Em and decreased surface expression of heteromeric Kv1 channels.ID: S0006295207001931; M3: Article; Accession Number: S0006295207001931; Author: L.C.

Processing Beyond Drawing: A Case Study Exploring Ideation for Teaching Design
Get PDFCitation: Orthel, B. D., & Day, J. K. (2016). Processing Beyond Drawing: A Case Study Exploring Ideation for Teaching Design. SAGE Open, 6(3). doi:10.1177/2158244016663285Designers’ internal thought processes can be externally expressed and represented through sketching and other forms of communication. Novice designers often struggle to communicate their ideas. This article reports an analysis of student design processes during conceptual and schematic design development with the intention to inform teaching and learning activities. Interior design student teams provided sketches, written journal entries, digital drawings and models, and graphic images to illustrate their collective design processes. The work was analyzed to understand the students’ representation and development of ideas. Analysis revealed that sketching, digital media, and non-graphic process work were all valuable in the students’ design process. Significantly, the strength of the design outcomes aligned more with the overall quality of conceptual process work, rather than the way in which students represented their ideas. Ultimately, student understanding of the design process varied. Teaching and learning activities should develop direct connections with design thinking processes to improve design education. © 2016, © The Author(s) 2016
Study of D+ -> K-pi(+)e(+)nu(e)
No full textÇetin, Serkant Ali (Dogus Author)We present an analysis of the decay D+ -> K-pi(+)e(+)nu(e) based on data collected by the BESIII experiment at the psi(3770) resonance. Using a nearly background-free sample of 18262 events, we measure the branching fraction B(D+ -> K-pi+e+nu e) = (3.77 +/- 0.03 +/- 0.08)%. For 0.8 K-pi+e+nu e)([0.8,1.0]) = (3.39 +/- 0.03 +/- 0.08)%. A partial wave analysis shows that the dominant (K) over bar* (892)degrees component is accompanied by an S-wave contribution accounting for (6.05 +/- 0.22 +/- 0.18)% of the total rate and that other components are negligible. The parameters of the (K) over bar* (892)degrees resonance and of the form factors based on the spectroscopic pole dominance predictions are also measured. We also present a measurement of the (K) over bar* (892)degrees helicity basis form factors in a model-independent way
Limitations and Precautions in the Use of the Farnsworth-Munsell Dichotomous D-15 Test
Get PDFSIGNIFICANCE: Clinicians who administer the Farnsworth-Munsell D-15 test need to pay attention to the quality and quantity of lighting and the time that they allow for completion of the test, and all repeat attempts need to be included in reports on compliance with color vision standards.
PURPOSE: The validity of the Farnsworth-Munsell D-15 has been questioned because practice may allow significantly color vision–deficient subjects to pass. In this article, we review the influence of practice and other factors that may affect the performance. These relate to both the design and the administration of the test.
METHODS: We review the literature and present some calculations on limitations in the colorimetric design of the test, quantity and quality of lighting, time taken, and repeat attempts.
RESULTS: In addition to the review of the literature, color differences and luminance differences under selected sources are calculated, and the increases in luminance clues under some sources and for protanopes are illustrated.
CONCLUSIONS: All these factors affect the outcome of the test and need specification and implementation if the test is to be applied consistently and equitably. We recommend the following: practitioners should never rely on a single color vision test regardless of the color vision standard; lighting should be Tcp 6500 K and Ra > 90; illuminance levels should be between 200 and 300 lux if detection of color vision deficiency is a priority
or between 300 and 1000 lux if the need is to test at the level where illuminance has minimal influence on performance; illuminance should be reported; time limits should be set between 1 and 2 minutes; repeat
testing (beyond the specified test and one retest) should be carried out only with authorization; and initial and repeated results should be reported. A set of test instructions to assist in the consistent application of the test is provided in the Appendix
