    This first Standard Chartered Bank: Women on Corporate Boards in India 2010 report looks at the representation of women on the boards of India's leading companies on the Bombay Stock Exchange (BSE-100) . It ranks the companies in terms of the gender diversity of their boards, with those with the highest percentage of women on their boards appearing at the top. The report also examines the general topic of gender diversity on the boards of the BSE-100 by presenting the findings of interviews with 18 female directors of BSE-100 companies

    Evolutionary significance of antiparasite, antipredator and learning phenotypes of avian nest defence

    Avian nest defence, which is expected to serve both antiparasite and antipredator functions, may benefit or be detrimental to birds, although selective forces that potentially operate on nest defence have not been quantified as a whole. Together with fitness values, we analysed two traits of nest defence, intensity and plasticity, in two distantly related passerine species, yellow warbler (Setophaga petechia) in North America and reed warbler (Acrocephalus scirpaceus) in Europe, both favourite host species for brood parasites. Breeders that escaped parasitism were the most vocal among reed warblers, whereas there was no specific defence phenotype that predicted prevention of parasitism in yellow warblers. Breeders that escaped nest predation were, in both species, those with the most distractive response at the first exposure to a nest-threatening event, such as the experimental predation or parasitism simulated at the nest. However, increasing defence intensity benefited yellow warblers but was detrimental to reed warblers, because intense defence responses attracted predators. Adaptiveness of nest defence was revealed by nest defence phenotypes when examined in concert with the seasonal fitness (i.e. measures of reproductive success). Results revealed selective forces favoured yellow warblers with strong defence phenotypes. Opposite forces were instead revealed among reed warblers whose favoured phenotypes were strong, yet less flexible, defenders

    Highly conductive Sb-doped layers in strained Si

    The ability to create stable, highly conductive ultrashallow doped regions is a key requirement for future silicon-based devices. It is shown that biaxial tensile strain reduces the sheet resistance of highly doped n-type layers created by Sb or As implantation. The improvement is stronger with Sb, leading to a reversal in the relative doping efficiency of these n-type impurities. For Sb, the primary effect is a strong enhancement of activation as a function of tensile strain. At low processing temperatures, 0.7% strain more than doubles Sb activation, while enabling the formation of stable, ~10-nm-deep junctions. This makes Sb an interesting alternative to As for ultrashallow junctions in strain-engineered complementary metal-oxide-semiconductor device

    Leading diversity in the boardroom: board evaluation project 2017

    This is the final version of the report.Listed companies are obligated to conduct annual internal evaluations and triennial external board evaluations. The board evaluation industry is concentrated in a small number of organisations conducting the majority of FTSE 350 companies’ evaluations. Recognising the evaluator community has rare and privileged access to Chairs, their boards, and witnessing the impact of boardroom composition, we conducted interviews with 11 experienced board evaluators, operating independently or within firms that offer wider sets of services, to ascertain their views on gender diversity in the boardroom. Board evaluation can be crudely divided into those focused on more procedural reviews and those engaging with behavioural elements. Our interviews revealed that, through more behaviourally focused reviews, board evaluators demonstrate a deep understanding of the impact they see of group composition on boardroom behaviour, culture and effectiveness. These evaluators were extremely clear about the considerable benefits of a critical mass of diversity in the boardroom (often defined as three ‘diverse’ individuals). They evidence this through the dynamics of debate and decision-making. Evaluators can advise Chairs on how to optimise the benefits of a diverse board, providing challenge and support, particularly in the areas of feedback, induction and developing a diverse pipeline of talent, in the pursuit of highly effective team performance. On the understanding that behavioural reviews are more likely to comprehensively address issues of diversity, we suggest that the Financial Reporting Council recommend that board evaluation disclosure in the Annual Report includes information on whether a behavioural or a procedural external evaluation was undertaken, in addition to a summary of actions taken since the evaluation. We also recommend that the board evaluation industry adopts minimum standards for reviews, in the form of a Code of Conduct, kitemark or other method, by mutual agreement. The minimum standards should address the areas raised in this report, i.e. on diversity and dynamics, culture and behaviour, on feedback, induction and the talent pipeline. Our findings are unique in terms of behavioural insight into the dynamics of the boardroom and should encourage more Chairs to strive for, and more investors to insist on, maximising the benefits of a critical mass of boardroom diversity

    An effective electrical isolation scheme by iron implantation at different substrate temperatures

    High-energy implantation of iron in n-type doped InP epilayers at different substrate temperatures: 77K, room temperature (RT), 100degreesC and 200degreesC was investigated to study the electrical isolation of n-type InP. Iron isolation implants were performed at 1MeV with a fluence of 5 x 10(14) /cm(2). This isolation scheme was chosen to place most of the iron atoms well inside the n-type doped layer. The sheet resistivity (R,), sheet carrier concentration (n(S)) and sheet mobility (p) were measured as a function of substrate temperature and post-implantation annealing temperature (100 - 800degreesC). Samples implanted at 77K, RT and 100degreesC show more or less the same trend of postimplant annealing characteristics. A maximum sheet resistivity of similar to1 x 10(7) Omega/rectangle was achieved for samples implanted at 77K, RT and 100degreesC after annealing at 400degreesC. A lower resistivity of similar to1 x 10(6) Omega/rectangle was obtained for a 200degreesC implant after annealing at 4000C. Lower damage accumulation due to enhanced dynamic annealing is observed for the highest implantation temperature. For 200degreesC substrate temperature, annealing above 4000C resulted in a gradual decrease in sheet resistivity to a value close to that of the starting material. But this is not the case for the lower substrate temperatures. The sheet resistivity was increased again for 77K, RT and 100()C implant after annealing at 600degreesC. We infer that for 77K, RT and 100degreesC implantation temperatures, the electrical isolation is due to a product of both damage related centers and defects related to the presence of Fe whereas for 200degreesC substrate temperature, we infer that only damage induced compensation removes the carriers. These results show the importance of iron implants as a device isolation scheme.</p
