In this paper, we investigate whether a regulation that mandates a greater proportion of outside directors on a corporate board results in a more independent board. Instead of taking the fraction of outside directors directly as the measure of board independence, we define it as the nominal independence level. The real independence level of the board is determined by both the nominal independen...

An underlying assumption in the executive compensation literature is that there is a national labor market for CEOs. The urban economics literature, however, documents higher ability among workers in large metropolitans, which results in a real and stable urban wage premium. In this paper, we investigate the link between the spatial clustering of firms in big, central cities (i.e., urban agglom...

BACKGROUND Cerium oxide (CeO(2)) nanoparticles have been posited to have both beneficial and toxic effects on biological systems. Herein, we examine if a single intratracheal instillation of CeO(2) nanoparticles is associated with systemic toxicity in male Sprague-Dawley rats. METHODS AND RESULTS Compared with control animals, CeO(2) nanoparticle exposure was associated with increased liver c...

To solve the lack of wear resistance of titanium alloys for use in biological applications, various prepared coatings on titanium alloys are often used as wear-resistant materials. In this paper, TiC bioinert coatings were fabricated on Ti6Al4V by laser cladding using mixed TiC and ZrO₂ powders as the basic pre-placed materials. A certain amount of CeO₂ powder was also added to the pre-placed p...

We phase-stabilized the carrier-envelope-offset (CEO) frequency of a SESAM modelocked Yb:CaGdAlO₄ (CALGO) thin disk laser (TDL) generating 90-fs pulses at a center wavelength of 1051.6 nm and a repetition rate of 65 MHz. By launching only 2% of its output power into a photonic crystal fiber, we generated a coherent octave-spanning supercontinuum spectrum. Using a standard f-to-2f interferometer...

In the last few decades, we have developed a substantial body of knowledge about CEO succession. However, except for some studies of family businesses that lack direct applicability to nonfamily CEO succession, the past studies of succession have not examined the very first succession event in a firm, when the Founder-CEO is replaced, on a largescale basis. The critical differences between late...

We investigate the contribution of co-worker-specific investments to the value of employment relationships between senior executives and firms. Given the difficulty in directly measuring co-worker-specific human capital, we take an indirect approach by analyzing the change in the composition of top management teams when a key member of the team (the CEO) departs. Our empirical analysis establis...

Cerium Oxide nanoparticles (CeO(2-x) NPs) are modified with polymer brushes of negatively charged poly (3-sulfopropylmethacrylate) (PSPM) and positively charged poly (2-(methacryloyloxy)ethyl-trimethylammonium chloride) (PMETAC) by Atom Transfer Radical Polymerisation (ATRP). CeO(2-x) NPs are fluorescently labelled by covalently attaching Alexa Fluor® 488/Fluorescein isothiocyanate to the NP su...

The percentage of S&P500 firms that offer ex-ante severance agreements to their CEOs grew from 20% in 1993 to more than 55% in 2007 despite controversial discussions on executive severance contracts in the media and academic studies. In addition, about 40% of firms offer their CEOs severance contracts with cash-only payouts. Our paper focuses on this recent spread of ex-ante CEO severance agree...

Chamomilla recutita (L.) Rauschert (Asteraceae), popularly known as chamomile, is a plant used in traditional medicine for various therapeutic purposes. Chamomile essential oil (CEO) is particularly known to inhibit the genotoxic damage produced by mutagens in mice somatic cells. The aim of this research was to determine the inhibitory potential of CEO on the genotoxic damage produced by daunor...
