We report on a polarization measurement of inclusive J/ψ mesons in the di-electron decay channel at mid-rapidity at 2 < pT < 6 GeV/c in p + p collisions at √s = 200 GeV. Data were taken with the STAR detector at RHIC. The J/ψ polarization measurement should help to distinguish between different models of the J/ψ production mechanism since they predict different pT dependences of the J/ψ polarization. In this analysis, J/ψ polarization is studied in the helicity frame. The polarization parameter λθ measured at RHIC becomes smaller towards high pT , indicating more longitudinal J/ψ polarization as pT increases. The result is compared with predictions of presently available models.
The ALICE Collaboration at the LHC reports measurement of the inclusive production cross section of electrons from semi-leptonic decays of beauty hadrons with rapidity |y| < 0.8 and transverse momentum 1 < pT < 10 GeV/c, in pp collisions at √s = 2.76 TeV. Electrons not originating from semi-electronic decay of beauty hadrons are suppressed using the impact parameter of the corresponding tracks. The production cross section of beauty decay electrons is compared to the result obtained with an alternative method which uses the distribution of the azimuthal angle between heavy-flavour decay electrons and charged hadrons. Perturbative QCD predictions agree with the measured cross section within the experimental and theoretical uncertainties. The integrated visible cross section, σb→e = 3.47 ± 0.40(stat) +1.12 −1.33(sys) ± 0.07(norm) μb, was extrapolated to full phase space using Fixed Order plus Next-to-Leading Log (FONLL) calculations to obtain the total bb production ¯ cross section, σbb¯ = 130 ± 15.1(stat) +42.1 −49.8(sys) +3.4 −3.1(extr) ± 2.5(norm) ± 4.4(BR) μb.
The growing role of IT in real estate asset management – the appraisal process as a master sample
(2014)
FINANCIAL SERVICE PROVIDERS FACE SERIOUS PROBLEMS IF MANY OF THEIR CUSTOMERS LEAVE QUICKLY BECAUSE SUCH CUSTOMERS HAVE LITTLE LONG-TERM VALUE. STILL, CURRENT REPORTING PRIMARILY FOCUSES ON CURRENT PROFITABILITY THAT REPRESENTS THE SHORT-TERM VALUE OF THE CUSTOMERS. THE LONG-TERM VALUE TYPICALLY RECEIVES LITTLE ATTENTION. CUSTOMER EQUITY REPORTING PRESENTS A MEANS TO FOCUS ON THE LONG-TERM VALUE OF THE COMPANY'S CUSTOMERS. IT AVOIDS THE RISK THAT SHORT-TERM PROFITS ARE INCREASED AT THE EXPENSE OF LONG-TERM VALUE CREATION AND ITS CENTRAL METRIC, CUSTOMER EQUITY, SERVES AS AN EARLY WARNING INDICATOR FOR RISK MANAGEMENT SYSTEMS THAT FOCUS ON CUSTOMER LOSS.

You reap what you sow! differences in knowledge exchange effectiveness between communication types
(2014)
FOR KNOWLEDGE-INTENSIVE ORGANIZATIONS IN THE FINANCE INDUSTRY, AN EFFECTIVE KNOWLEDGE EXCHANGE AMONG EMPLOYEES IS CRUCIAL FOR THE COMPETITIVE PERFORMANCE. THEREFORE, COMPANIES INCREASINGLY RELY ON SOCIAL MEDIA PLATFORMS TO FACILITATE COMMUNICATION AND COLLABORATION. TO ENHANCE OUR UNDERSTANDING OF SUCCESSFUL COMMUNICATION IN ENTERPRISE SOCIAL MEDIA, WE APPLY HUMAN CODING AND QUANTITATIVE ANALYSIS TO THE CONTENT AND TONE OF 15,505 ENTERPRISE MICROBLOGGING MESSAGES CREATED BY 1,166 EMPLOYEES OF AN INTERNATIONAL FINANCIAL SERVICE PROVIDER. OUR RESULTS SUGGEST THAT A MORE FACTUAL-ORIENTED COMMUNICATION TYPE BENEFITS FROM A HIGHER KNOWLEDGE EXCHANGE EFFECTIVENESS COMPARED TO A PRIMARILY SELF-DISCLOSING COMMUNICATION TYPE.
ALMOST 20% OF THE GERMAN POPULATION CURRENTLY HOLDS A CONSUMER LOAN. DESPITE ITS OBVIOUS IMPORTANCE FOR A PRIVATE HOUSEHOLD’S BALANCE SHEET, WE KNOW SURPRISINGLY LITTLE ABOUT IT. ONE PURPOSE OF THIS STUDY IS TO GIVE AN OVERVIEW OF THE GERMAN CONSUMER/INSTALLMENT LOAN MARKET. WE COMPARED FIVE WIDELY ACCEPTED DATA SOURCES AND FOUND DIFFERENCES IN THE LOAN PARTICIPATION RATE, EVEN ON AN AGGREGATED NATIONWIDE LEVEL. IN A SECOND STEP, WE TRY TO FIND REASONS FOR EXTRAORDINARY HIGH GROWTH RATES AMONG SENIORS’ DEBT PARTICIPATION RATES.
