Examining the Antecedents and Consequences of Corporate Reputation: A Customer Perspective

Abstract: This paper extends previous work to examine the antecedents and customer-related consequences of corporate reputation for one important stakeholder group, customers, and within a special service sector where product and corporate associations are synonymous. We begin by linking the concept of corporate reputation to related concepts. Then, using structural equation modelling on customer survey data (n=511), we examine the impact of customer satisfaction and trust on corporate reputation, as well as how corporate reputation affects customer loyalty and word of mouth behaviour. The management implications of these results are discussed.

Measurement of the gamma gamma* --> pi0 transition form factor

Abstract: We study the reaction e+e- --> e+e-pi0 and measure the gamma gamma* --> pi0 transition form factor in the momentum transfer range from 4 to 40 GeV^2. The analysis is based on 442 fb^-1 of integrated luminosity collected at PEP-II with the BABAR detector at e+e- center-of-mass energies near 10.6 GeV.

Precise measurement of the e+e-→π+π-(γ) cross section with the initial-state radiation method at BABAR

Abstract: A precise measurement of the cross section for the process e^+e^- → K^+K^-(γ) from threshold to an energy of 5 GeV is obtained with the initial-state radiation (ISR) method using 232 fb^(-1) of data collected with the BABAR detector at e^+e^- center-of-mass energies near 10.6 GeV. The measurement uses the effective ISR luminosity determined from the e^+e^- → μ^+μ^-(γ)γ_(ISR) process with the same data set. The corresponding lowest-order contribution to the hadronic vacuum polarization term in the muon magnetic anomaly is found to be a_μ^(KK,LO)=(22.93 ± 0.18_(stat) ± 0.22_(syst))×10^(-10). The charged kaon form factor is extracted and compared to previous results. Its magnitude at large energy significantly exceeds the asymptotic QCD prediction, while the measured slope is consistent with the prediction.

Evidence for X(3872)→ψ(2S)γ in B±→X(3872) K± Decays and a Study of B→cc̄γK

Abstract: In a search for B --> ccbar gamma K decays with the BaBar detector, where ccbar includes J/psi and psi(2S), and K includes K+, Ks, and K*(892), we find evidence for X(3872) --> J/psi gamma and X(3872) --> psi(2S) gamma with 3.6 sigma and 3.5 sigma significance, respectively. We measure the product of branching fractions BR(B+ --> X(3872) K+) x BR(X(3872) --> J/psi gamma) = (2.8 +/- 0.8(stat.) +/- 0.2(syst.)) x 10^(-6) and BR(B+ --> X(3872) K+) x BR(X(3872) --> psi(2S) gamma) = (9.9 +/- 2.9(stat.) +/- 0.6(syst.)) x 10^(-6).

Search for Dimuon Decays of a Light Scalar Boson in Radiative Transitions Υ→γA0

Abstract: We search for evidence of a light scalar boson in the radiative decays of the {Upsilon}(2S) and {Upsilon}(3S) resonances: {Upsilon}(2S, 3S) {yields} {gamma}A{sup 0}, A{sup 0} {yields} {mu}{sup +}{mu}{sup -}. Such a particle appears in extensions of the Standaard Model, where a light CP-odd Higgs boson naturally couples strongly to b-quarks. We find no evidence for such processes in the mass range 0.212 {<=} m{sub A{sup 0}} {<=} 9.3 GeV in the samples of 99 x 10{sup 6} {Upsilon}(2S) and 122 x 10{sup 6} {Upsilon}(3S) decays collected by the BABAR detector at the PEP-II B-factory and set stringent upper limits on the effective coupling of the b quark to the A{sup 0}. We also limit the dimuon branching fraction of the {eta}{sub b} meson: {Beta}({eta}{sub b} {yields} {mu}{sup +}{mu}{sup -}) < 0.9% at 90% confidence level.

Measurement of time-dependent CP asymmetry in B0→cc̄K(*)0 decays

Abstract: We present updated measurements of time-dependent CP asymmetries in fully reconstructed neutral B decays containing a charmonium meson. The measurements reported here use a data sample of (465 +/- 5)x10(6) Upsilon(4S)-> B B decays collected with the BABAR detector at the PEP-II asymmetric energy e(+)e(-) storage rings operating at the SLAC National Accelerator Laboratory. The time-dependent CP asymmetry parameters measured from J psi K-S(0), J psi K-L(0), psi(2S)K-S(0), eta K-c(S)0, chi K-c1(S)0, and J/psi K-*(892)(0) decays are: C-f=0.024 +/- 0.020(stat)+/- 0.016(syst) and -eta S-f(f)=0.687 +/- 0.028(stat)+/- 0.012(syst).

Study of DsJ decays to D*K in inclusive e+e- interactions

Abstract: We observe the decays D*_(s1)(2710)^+ → D*K and D*_(sJ)(2860)^+ → D*K and measure their branching fractions relative to the DK final state. We also observe, in the D*K mass spectrum, a new broad structure at a mass of (3044 ± 8_(stat)(^(+30)_(-5))_(syst)) MeV/c^2 having a width Γ =(239 ± 35_(stat)(^(+46)_(-42))_(syst)) MeV. To obtain this result we use 470 fb^(-1) of data recorded by the BABAR detector at the PEP-II asymmetric-energy e^+e^- storage rings at the Stanford Linear Accelerator Center running at center-of-mass energies near 10.6 GeV.

Angular distributions in the decay B -> K*l(+)l(-)

Abstract: We use a sample of 384 million BBbar events collected with the Babar detector at the PEP-II e+e- collider to study angular distributions in the rare decays B -> K* l+l-, where l+l- is either e+e- or mu+mu-. For low dilepton invariant masses, m(l+l-) 3.2$ GeV/c^2, we measure AFB=0.76 (+0.52,-0.32) +/- 0.07 FL=0.71 (+0.20,-0.22) +/- 0.04.

Direct CP, Lepton Flavor and Isospin Asymmetries in the Decays B->K(*)l+l-

Abstract: We measure branching fractions and integrated rate asymmetries for the rare decays B -> K((*))l(+)l(-), where l(+)l(-) is either e(+)e(-) or mu(+)mu(-), using a sample of 384x10(6) BB events collected with the BABAR detector at the PEP-II e(+)e(-) collider. We find no evidence for direct CP or lepton-flavor asymmetries. However, for dilepton masses below the J/psi resonance, we find evidence for unexpectedly large isospin asymmetries in both B -> Kl(+)l(-) and B -> K(*)l(+)l(-) which differ, respectively, by 3.2 sigma and 2.7 sigma, including systematic uncertainties, from the standard model expectations.

Evidence for the ηb(1S) Meson in Radiative Υ(2S) Decay

Abstract: We have performed a search for the eta_b(1S) meson in the radiative decay of the Upsilon(2S) resonance using a sample of 91.6 million Upsilon(2S) events recorded with the BABAR detector at the PEP-II B factory at the SLAC National Accelerator Laboratory. We observe a peak in the photon energy spectrum at E_gamma = 610.5 {+4.5} {-4.3} (stat) +/- 1.8 (syst) MeV, corresponding to an eta_b(1S) mass of 9392.9 {+4.6} {-4.8} (stat) +/- 1.9 (syst) MeV/c^2. The branching fraction for the decay Upsilon(2S) --> gamma eta_b(1S) is determined to be (4.2 {+1.1} {-1.0} (stat) +/- 0.9 (syst)) x 10^(-4). The ratio B(Upsilon(2S) --> gamma eta_b(1S))/B(Upsilon(3S) --> gamma eta_b(1S)) = 0.89 {+0.25} {-0.23} (stat) {+0.12}{-0.16} (syst) is consistent with the ratio expected for magnetic dipole transitions to the eta_b(1S) meson.

Time-dependent amplitude analysis of B0 -> KS0π+π-

Abstract: We perform a time-dependent amplitude analysis of B^0→K_S^0π^+π^- decays to extract the CP violation parameters of f_0(980)K_S^0 and ρ^0(770)K_S^0 and the direct CP asymmetry of K^(*+)(892)π^-. The results are obtained from a data sample of (383±3)×10^6 BB decays, collected with the BABAR detector at the PEP-II asymmetric–energy B factory at SLAC. We find two solutions, with an equivalent goodness-of-fit. Including systematic and Dalitz plot model uncertainties, the combined confidence interval for values of the CP parameter β_(eff) in B^0 decays to f_0(980)K_S^0 is 18°<β_(eff)<76° at 95% confidence level (C.L). CP conservation in B^0 decays to f_0(980)K_S^0 is excluded at 3.5 standard deviations including systematic uncertainties. For B^0 decays to ρ^0(770)K_S^0, the combined confidence interval is -9°<β_(eff)<57° at 95% C.L. In decays to K^(*+)(892)π^- we measure the direct CP asymmetry to be A_(CP)=-0.20±0.10±0.01±0.02. The measured phase difference (including B^0B ^0 mixing) between decay amplitudes of B^0→K^(*+)(892)π^- and B ^0→K^(*-)(892)π^+, excludes the interval -137°<ΔΦ(K^(*+)(892)π^-)<-5° at 95% C.L.

Search for a Low-Mass higgs boson in Υ(3S)→γA0, A0→τ+τ- at BABAR

Abstract: We search for a light Higgs boson, $A^0$, in the radiative decay $\Upsilon(3S)\to\gamma A^0$, $A^0\to\tau^+\tau^-$, $\tau^+\to e^+ u_e \overline{ u}_{\tau}$ or $\tau^+\to \mu^+ u_{\mu} \overline{ u}_{\tau}$. The data sample contains 122 million $\Upsilon(3S)$ events recorded with the \babar detector. We find no evidence for a narrow structure in the studied $\tau^+\tau^-$ invariant mass region of $4.03(1.5-16)\times 10^{-5}$ across the $m_{\tau^+\tau^-}$ range. We also set a 90% C.L. upper limit on the $\tau^+\tau^-$-decay of the $\eta_b$ at ${\mathcal{B}}(\eta_b\to \tau^+\tau^-)<8%$.

Search for invisible decays of the Υ(1S)

Abstract: We search for invisible decays of the Upsilon(1S) meson using a sample of 91.4 x 10(6) Upsilon(3S) mesons collected at the BABAR/PEP-II B factory. We select events containing the decay Upsilon(3S) --> pi(+)pi(-)Upsilon(1S) and search for evidence of an undetectable Upsilon(1S) decay recoiling against the dipion system. We set an upper limit on the branching fraction B(Upsilon(1S) --> invisible) < 3.0 x 10(-4) at the 90% confidence level.

Measurement of semileptonic B decays into orbitally excited charmed mesons.

Abstract: We present a study of B decays into semileptonic final states containing charged and neutral D-1(2420) and D-2*(2460). The analysis is based on a data sample of 208 fb(-1) collected at the Y(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. With a simultaneous fit to four different decay chains, the semileptonic branching fractions are extracted from measurements of the mass difference Delta m = m(D**) - m(D) distribution. Product branching fractions are determined to be B(B+ -> D(1)(0)l(+)nu(l)) x B(D-1(0) -> D*+pi(-)) = (2.97 +/- 0.17 +/- 0.17) x 10(-3), B(B+ -> D-2*l(+)nu(e)) x B(D-2*(0) -> D(*)+pi(-)) = (2.29 +/- 0.23 +/- 0.21) x 10(-3), B(B-0 -> D(1)(-)l(+)nu(l)) x B(D-1(-) -> D*(0)pi(-)) = (2.78 +/- 0.24 +/- 0.25) x 10(-3) and B(B-0 -> D-2*(-)l(+)nu(l)) x B(D-2(*-) -> D-(*)0 pi(-)) = (1.77 +/- 0.26 +/- 0.11) x 10(-3). In addition we measure the branching ratio Gamma(D2* -> D pi(-))/Gamma(D-2* -> D-(*)pi(-)) = 0.62 +/- 0.03 +/- 0.02.

Measurements of the τ mass and the mass difference of the τ + and τ - at BABAR

Abstract: We present the result from a precision measurement of the mass of the tau lepton, M-tau, based on 423 fb(-1) of data recorded at the Upsilon(4S) resonance with the BABAR detector. Using a pseudomass endpoint method, we determine the mass to be 1776.68 +/- 0.12(stat)+/- 0.41(syst) MeV. We also measure the mass difference between the tau(+) and tau(-), and obtain (M-tau(+)-M-tau(-))/M-AVG(tau)=(-3.4 +/- 1.3(stat)+/- 0.3(syst))x10(-4), where M-AVG(tau) is the average value of M-tau(+) and M-tau(-).

Improved Measurement of B+→ρ+ρ0 and Determination of the Quark-Mixing Phase Angle α

Abstract: We present improved measurements of the branching fraction ${\cal B}$, the longitudinal polarization fraction $f_L$, and the direct {\ensuremath{CP}\xspace} asymmetry {\ensuremath{{\cal A}_{CP}}\xspace} in the $B$ meson decay channel $B^+\to\rho^+\rho^0$. The data sample was collected with the {{\slshape B\kern-0.1em{\smaller A}\kern-0.1em B\kern-0.1em{\smaller A\kern-0.2em R}}} detector at SLAC. The results are ${\cal B} (\Bp\ra\rprz)=(23.7\pm1.4\pm1.4)\times10^{-6}$, $f_L=0.950\pm0.015\pm0.006$, and $\Acp=-0.054\pm0.055\pm0.010$, where the uncertainties are statistical and systematic, respectively. Based on these results, we perform an isospin analysis and determine the CKM weak phase angle $\alpha$ to be $(92.4^{+6.0}_{-6.5})^{\circ}$.

Model-independent search for the decay B+→l+νlγ

Abstract: We present a search for the radiative leptonic decay B^+ → l^+ν_lγ, where l = e, μ, using a data sample of 465 × 10^6 BB(overbar) pairs collected by the BABAR experiment. In this analysis, we fully reconstruct the hadronic decay of one of the B mesons in Υ(4S) → B^+B^- decays, then search for evidence of B^+ → l^+ν_lγ in the rest of the event. We observe no significant evidence of signal decays and report model-independent branching fraction upper limits of B(B^+ → e^+ν_eγ) < 17 × 10^(-6), B(B^+ → μ^+ν_μγ) < 24 × 10^(-6), and B(B^+ → l^+ν_lγ) < 15.6 × 10^(-6) (l= e or μ), all at the 90% confidence level.

Measurements of time-dependent CP asymmetries in B0 --> D(*)+D(*)- decays

Abstract: We present new measurements of time-dependent CP asymmetries for B{sup 0} {yields} D{sup (*)+}d{sup (*)-} decays using (467 {+-} 5) x 10{sup 6} B{bar B} pairs collected with the BABAR detector located at the PEP-II B Factory at the Stanford Linear Accelerator Center. We determine the CP-odd fraction of the B{sup 0} {yields} D*{sup +}D*{sup -} decays to be R{perpendicular} = 0.158 {+-} 0.028 {+-} 0.006 and find CP asymmetry parameters for the CP-even component of the decay S{sub +} = -0.76 {+-} 0.16 {+-} 0.04 and C{sub +} = 0.00 {+-} 0.12 {+-} 0.02. We measure S = -0.63{+-}0.36{+-}0.05 and C = -0.07{+-}0.23{+-}0.03 for B{sup 0} {yields} D{sup +}D{sup -}, S = -0.62{+-}0.21{+-}0.03 and C = 0.08 {+-} 0.17 {+-} 0.04 for B{sup 0} {yields} D*{sup +}D{sup -}, and S = -0.73 {+-} 0.23 {+-} 0.05 and C = 0.00 {+-} 0.17 {+-} 0.03 for B{sup 0} {yields} D{sup +}D*{sup -}. For the B{sup 0} {yields} D*{sup {+-}}D{sup {-+}} decays, we also determine the CP-violating asymmetry A = 0.008 {+-} 0.048 {+-} 0.013. In each case, the first uncertainty is statistical and the second is systematic. The measured values for the asymmetries are all consistent with the Standard Model.

Constraints on the CKM angle γ in B0→D̄0K*0 and B0→D0K*0 from a Dalitz analysis of D0 and D̄0 decays to KSπ+π-

Abstract: We present constraints on the angle γ of the unitarity triangle with a Dalitz analysis of neutral D decays to KSπ+π- from the processes B0→D0K*0 (B0→D0K*0) and B0→D0K*0 (B0→D0K*0) with K*0→K+π- (K*0→K-π+). Using a sample of 371×106 BB pairs collected with the BABAR detector at PEP-II, we constrain the angle γ as a function of rS, the magnitude of the average ratio between b→u and b→c amplitudes. © 2009 The American Physical Society.

Search for lepton flavor violating decays τ-→l-Ks0 with the BABAR experiment

Abstract: A search for the lepton flavor violating decays τ^- → l^- K^0_S (l = e or µ) has been performed using a data sample corresponding to an integrated luminosity of 469 fb-1, collected with the BABAR detector at the SLAC PEP-II e^+e^- asymmetric energy collider. No statistically significant signal has been observed in either channel and the estimated upper limits on branching fractions are B(τ^- → e^- K^0_S) < 3.3 × 10^(-8) and B(τ^- → µ^- K^0_S) < 4.0 × 10^(-8) at 90% confidence level.

SSR and post-conflict reconstruction: armed wing of state-building?

Abstract: This paper directly challenges some of the popular SSR mythology that has grown around the UK’s involvement in Sierra Leone and the subsequent policy developments associated with SSR. It raises questions about the underlying political assumptions of the SSR process and contemporary SSR material, much of which lacks analysis of underlying theories of SSR relating to broader state building and construction of a liberal peace. Using a case taken from the reconstruction of Sierra Leone this paper outlines some of the key issues emerging after ten years of reconstruction efforts. Sierra Leone is usually over-cited, but given its importance to any orthodoxy that may be said to exist, it is relevant here. Fundamentally, Sierra Leone remains a relatively small state in West Africa and the fact a viable state remains elusive challenges assumptions about time taken in reconstructing socio-political norms and structures, and also questions state-building as a post conflict approach. This paper will argue that SSR in Sierra Leone was never a developed strategy but came to represent a series of policies that evolved on the ground largely as the result of the interaction of individuals and groups engaged in those early decisions, sometimes against the wishes of Whitehall, but always sharing a ‘direction of travel’. This is an important point in terms of how SSR policy was actually developed and also how approaches come to be seen as being far smoother and well planned with hindsight but also in terms of how policy-makers and academics can learn about social, governance and security processes. Finally the paper moves on to analyse what lessons can and can’t be drawn from this experience and what the implications are for SSR going forward. It argues that the example of Sierra Leone as a ‘classic’ post conflict situation is enlightening but also damaging in the sense that any future SSR intervention will face radically different circumstances and needs to take into account broader issues of state-building and in particular recognising the deeply political aspects of what is being done when an international agency engages in SSR.

‘Negotiating with Ghosts’: Religion, Conflict and Peace in Northern Uganda

Abstract: This article outlines the current situation with regard to the Lord's Resistance Army and the possibilities for peace in Northern Uganda. It seeks to add to the discourse on rethinking Africa's international relations in the context of a specific conflict and with regard to a specific tool of the international community: the International Criminal Court (ICC) and its involvement in issuing warrants for insurgency leaders in October 2005. The article discusses the role of traditional justice systems and the ICC in ending the war, concluding that justice in Northern Uganda requires an end to the false dichotomy of ‘traditional’ and ICC approaches and that the two must complement each other in order to address the different groups within the LRA and the Acholi population.

Triggering on Long-Lived Neutral Particles in the ATLAS Detector

Abstract: Neutral particles with long decay paths that decay to many-particle final states represent, from an experimental point of view, a challenge both for the trigger and for the reconstruction capabilities of the ATLAS apparatus. The Hidden Valley scenario serves as an excellent setting for the purpose of exploring the challenges to the trigger posed by long-lived particles.

Measurement of CP violation observables and parameters for the decays B±→DK*±

Abstract: We study the decay B--> DK*- using a sample of 379x10(6) Upsilon(4S)-> BB events collected with the BABAR detector at the PEP-II B factory. We perform a Gronau-London-Wyler analysis where the D meson decays into either a CP-even (CP+) eigenstate (K+K-, pi(+)pi(-)), CP-odd (CP-) eigenstate (K-S(0)pi(0), K-S(0)phi, K-S(0)omega) or a non-CP state (K-pi(+)). We also analyze D meson decays into K+pi(-) from a Cabibbo-favored D-0 decay or doubly suppressed D-0 decay [Atwood-Dunietz-Soni (ADS) analysis]. We measure observables that are sensitive to the Cabibbo-Kobayashi-Maskawa angle gamma: the partial-rate charge asymmetries A(CP +/-), the ratios R-CP +/- of the B-decay branching fractions in CP +/- and non-CP decay, the ratio R-ADS of the charge-averaged branching fractions, and the charge asymmetry A(ADS) of the ADS decays: A(CP+)=0.09 +/- 0.13 +/- 0.06, A(CP-)=-0.23 +/- 0.21 +/- 0.07, RCP+=2.17 +/- 0.35 +/- 0.09, RCP-=1.03 +/- 0.27 +/- 0.13, R-ADS=0.066 +/- 0.031 +/- 0.010, and A(ADS)=-0.34 +/- 0.43 +/- 0.16, where the first uncertainty is statistical and the second is systematic. Combining all the measurements and using a frequentist approach yields the magnitude of the ratio between the Cabibbo-suppressed and favored amplitudes, r(B)=0.31 with a one (two) sigma confidence level interval of [0.24, 0.38] ([0.17, 0.43]). The value r(B)=0 is excluded at the 3.3 sigma level. A similar analysis excludes values of gamma in the intervals [0, 7]degrees, [55, 111]degrees, and [175, 180]degrees ([85, 99]degrees) at the one (two) sigma confidence level.

Measurement of the B+→ωl+ν and B+→ηl+ν branching fractions

Abstract: We present a study of the charmless semileptonic B-meson decays B{sup +}{yields}{omega}l{sup +}{nu} and B{sup +}{yields}{eta}l{sup +}{nu}. The analysis is based on 3.83x10{sup 8} BB pairs recorded at the {upsilon}(4S) resonance with the BABAR detector. The {omega} mesons are reconstructed in the channel {omega}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0} and the {eta} mesons in the channels {eta}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0} and {eta}{yields}{gamma}{gamma}. We measure the branching fractions B(B{sup +}{yields}{omega}l{sup +}{nu})=(1.14{+-}0.16{sub stat}{+-}0.08{sub syst})x10{sup -4} and B(B{sup +}{yields}{eta}l{sup +}{nu})=(0.31{+-}0.06{sub stat}{+-}0.08{sub syst})x10{sup -4}.

Observation and polarization measurement of B0→a1(1260)+a1(1260)- decay

Abstract: We present measurements of the branching fraction B and longitudinal polarization fraction fL for B0→a1(1260)+a1(1260)- decays, with a1(1260)±→π-π+π±. The data sample, collected with the BABAR detector at the SLAC National Accelerator Laboratory, represents 465×106 produced BB pairs. We measure B(B0→a1(1260)+a1(1260)-)×[B(a1(1260)+→π-π+π+)]2= (11.8±2.6±1.6)×10-6 and fL=0.31±0.22±0.10, where the first uncertainty is statistical and the second systematic. The decay mode is measured with a significance of 5.0 standard deviations including systematic uncertainties.

Search for B0 meson decays to π0KS0KS0, ηkS0KS0, and η′KS0KS0

Abstract: We describe searches for B{sup 0} meson decays to the charmless final states {pi}{sup 0}K{sub S}{sup 0}K{sub S}{sup 0}, {eta}K{sub S}{sup 0}K{sub S}{sup 0}, and {eta}{prime}K{sub S}{sup 0}K{sub S}{sup 0}. The data sample corresponds to 467 x 10{sup 6} B{bar B} pairs produced in e{sup +}e{sup -} annihilation and collected with the BABAR detector at the SLAC National Accelerator Laboratory. We find no significant signals and determine the 90% confidence level upper limits on the branching fractions, in units of 10{sup -7}, {Beta}(B{sup 0} {yields} {pi}{sup 0}K{sub S}{sup 0}K{sub S}{sup 0}) < 12, {Beta}(B{sup 0} {yields} {eta}K{sub S}{sup 0}K{sub S}{sup 0}) < 10, and {Beta}(B{sup 0} {yields} {eta}{prime}K{sub S}{sup 0}K{sub S}{sup 0}) < 20.

Search for B-meson decays to b1ρ and b1K*

Abstract: We present a search for decays of B mesons to final states with a b(1) meson and a rho or K*(d892) meson. The search is based on a data sample consisting of 465 million B (B) over bar pairs collected by the BABAR detector at the SLAC National Accelerator Laboratory. We do not observe any statistically significant signal. The upper limits we set on the branching fractions range from 1.4 to 8.0 x 10(-6) at the 90% confidence level, including systematic uncertainties.

Knowledge elicitation and mapping: Ontology as an instrument of design and organizational learning

Abstract: AbstrAct This chapter is concerned with engaging end-users in the design and development of knowledge management systems. The identification, capture and use of contextual knowledge in the design of knowledge management systems (KMS) are key development activities. It is argued that tacit knowledge, while often difficult to capture, can be extremely useful as contextualising knowledge to designers of KM systems. A methodology was developed to combine soft systems methodology, causal cognitive mapping, and brainstorming to provide a set of knowledge requirements. The methodology appears to offer an effective platform for making sense of non-routine yet rigorous knowledge work. The interventions enacted by the consultant and involving project stakeholders and end users facilitates individual, group and organizational learning through a metacognitive process of understanding the relationships and dynamics of shared group knowledge. Engagement with the methodology, in addition to causing tacit knowledge to be made explicit, enables second-order 'deutero learning', or 'learning how to learn'. The combination of activities presented forms a metacognitive process which is both a form of proactive individual and organizational learning and an endeavour which adds to organizational memory. The identification, capture and use of contextual knowledge and their use in engaging end-users in the design of KMS will result in better user-system interaction.
