44 / n recent years, business leaders have gained great popularity: Lee Iaccoca and Steven Jobs, for example, have stepped into the limelight as agents of change and entrepreneurship. But though we tend to think of the positive outcomes associated with leaders, certain risks or liabilities are also entailed. The very behaviors that distinguish leaders from managers also have the potential to pr...

Standardized in 1976 as a uniform color space, CIELAB is extensively utilized in color science and engineering applications. CIELAB provides both a color difference formula and correlates for common perceptual descriptors of color. Deficiencies in both areas are well-known, and based on these known limitations, numerous fixes have been developed yielding alternative color difference formulae th...

Cytokines have been implicated in a variety of physiological processes involving lymphoid tissue development, lymphocyte activation, and control of regenerative processes such as wound healing. The first characterization of a cytokine implicated in abolishing or killing tumor cells – the tumor necrosis factor (TNF) – fostered and boosted a completely new field of research that in addition to ca...

reported, e.g. increases in cell adhesion, coagulation and proinflammatory molecules [3, 4] . Increases in C-reactive protein have also been demonstrated [5] . In this issue of Respiration Tanriverdi et al. [6] confirm studies that demonstrated anatomical and functional changes in the blood vessels of patients with obstructive sleep apnea. They used newly developed noninvasive ultrasonographic ...

Dear Editor, Curcumin is a yellow–orange pigment obtained from the plant Curcuma longa. The powdered rhizome of this plant, called turmeric, is a common ingredient in curry powders and has a long history of use in traditional Asian medicine for a wide variety of disorders. In the last decade a large number of reports have been published on the beneficial effects of curcumin, and it has repeated...

Geometrical tests such as the combination of the Hubble parameter H(z) and the angular diameter distance dA(z) can, in principle, break the degeneracy between the dark energy equation of state parameter w(z), and the spatial curvature Ωk in a direct, model-independent way. In practice, constraints on these quantities achievable from realistic experiments, such as those to be provided by Baryon ...

We study the μ < 0 branch of the minimal supergravity ansatz of the minimal supersymmetric standard model. The extent to which μ < 0 is disfavoured compared to μ > 0 in global fits is calculated with Markov Chain Monte Carlo methods and bridge sampling. The fits include state-of-the-art two-loop MSSM contributions to the electroweak observables MW and sin 2 θ w, as well as the anomalous magneti...

How does finance affect employment and inter-industry job reallocations? We present a model that predicts that financial development (i) raises employment and wages, its impact being smaller at high levels of the equilibrium wage and financial development; (ii) may induce either more or less job reallocations, depending on whether shocks to profit opportunities or to cash flow are more prevalen...
