In an economy driven by ideas and intellectual know-how, top executives recognize the importance of employing smart, highly creative people. But if clever people have one defining characteristic, it's that they do not want to be led. So what is a leader to do? The authors conducted more than 100 interviews with leaders and their clever people at major organizations such as PricewaterhouseCooper...

Using the next-to-leading order low energy effective Hamiltonian for |∆B| = 1, ∆C = ∆U = 0 transitions, the contributions of electroweak penguin operators in B−(B0 d) → PP and PV decays are estimated in the standard model. We find that, for some channels, the electroweak penguin effects can enhance or reduce the QCD penguin and/or tree level contributions by at least 30%, and can even play domi...

Systems development has become increasingly complex over the last decades; project teams must respond not only to the concerns of the classical engineering disciplines (such as electrical and mechanical engineering) and software engineering, but also to stakeholder demands for more capable, integrated, distributed, and optimized systems. Those who manage the development of these new systems fac...

Current fragmentation in semiinclusive deep inelastic leptoproduction offers, besides refinement of inclusive measurements such as flavor separation and access to the chiral-odd quark distribution functions hq1(x) = δq(x), the possibility to investigate intrinsic transverse momentum of hadrons via azimuthal asymmetries. LEADING QUARK DISTRIBUTION FUNCTIONS In deep-inelastic leptoproduction (DIS...

Tinea or dermatophytoses are of skin superficial and fungous infections affecting keratinized tissues such as hair, nail, and superficial layer of epidermis. This study aimed at evaluating some predisposing factors for tinea corporis, because elimination or treatment of them not only ceases spreading of the lesion but also prevents reinfection. In this descriptive cross-sectional study patients...

We analyze a game theoretic model of social learning about a consumption good with endogenous timing and heterogeneous accuracy of private information. We show that if individuals value their reputation for the degree to which they are informed, this reduces the incentive to learn by observing others and exacerbates the incentive to consume the good before others, i.e., to attempt to be an “opi...

Goal: After completing this continuing education article the reader will be able to: understand the importance of ensuring appropriate leadership support and operational infrastructure are dedicated to the improvement of safe medication use, describe the importance of proper alignment between medication safety principles and front-line practice, and develop an initial plan for improving medicat...

We show that perturbation theory may give reasonable numbers for the decays of the bottomonium and charmonium ground states to e + e − and to γγ. To reach this conclusion it is important to perform the resummation of logs. In particular, we obtain the value Γ(η b (1S) → γγ) = 0.35 ± 0.1(th.) ± 0.05(Λ QCD) KeV.

ow what?” I asked myself. At the time I was the assistant pharmacy director at Sinai Hospital of Detroit and had just been appointed acting director until the permanent director of pharmacy was secured. I was one year out of my residency and a graduate student with the summer to devote to the operation of the hospital pharmacy. I was “as green as a stick” and did not have much of a clue about s...

The renormalization group evolution of ∆B = 2 transition operators is studied at leading order in heavy quark effective theory and at next-to-leading order in QCD. We calculate new contributions that were not taken into account in previous work and obtain the complete result to next-to-leading logarithmic accuracy. The various scheme and scale dependences and their cancellation in physical quan...
