Corporate Social Responsibility and Firm Performance: Investor Preferences and Corporate Strategies

Abstract: Debates continue to rage between those that argue that managers should maximize the present value of their firm's cash flows in making strategic choices and those that argue that, sometimes, the wealth maximizing interests of a firm's equity holders should be abandoned for the good of a firm's other stakeholders. This debate is addressed by proposing a theoretical model in which the supply of and demand for socially responsible investment opportunities determines whether these activities will improve, reduce, or have no impact on a firm's market value. The theory shows that managers in publicly traded firms might fund socially responsible activities that do not maximize the present value of its future cash flows yet still maximize the market value of their firm.

Sample size in factor analysis: The role of model error

Abstract: This article examines effects of sample size and other design features on correspondence between factors obtained from analysis of sample data and those present in the population from which the samples were drawn. We extend earlier work on this question by examining these phenomena in the situation in which the common factor model does not hold exactly in the population. We present a theoretical framework for representing such lack of fit and examine its implications in the population and sample. Based on this approach we hypothesize that lack of fit of the model in the population will not, on the average, influence recovery of population factors in analysis of sample data, regardless of degree of model error and regardless of sample size. Rather, such recovery will be affected only by phenomena related to sampling error which have been studied previously. These hypotheses are investigated and verified in two sampling studies, one using artificial data and one using empirical data.

Stability and Exfoliation of Germanane: A Germanium Graphane Analogue

Abstract: Graphene’s success has shown not only that it is possible to create stable, single-atom-thick sheets from a crystalline solid but that these materials have fundamentally different properties than the parent material. We have synthesized for the first time, millimeter-scale crystals of a hydrogen-terminated germanium multilayered graphane analogue (germanane, GeH) from the topochemical deintercalation of CaGe2. This layered van der Waals solid is analogous to multilayered graphane (CH). The surface layer of GeH only slowly oxidizes in air over the span of 5 months, while the underlying layers are resilient to oxidation based on X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy measurements. The GeH is thermally stable up to 75 °C; however, above this temperature amorphization and dehydrogenation begin to occur. These sheets can be mechanically exfoliated as single and few layers onto SiO2/Si surfaces. This material represents a new class of covalently terminated graphane analogue...

The Chameleon Effect as Social Glue: Evidence for the Evolutionary Significance of Nonconscious Mimicry

Abstract: The "chameleon effect" refers to the tendency to adopt the postures, gestures, and mannerisms of interaction partners (Chartrand & Bargh, 1999) This type of mimicry occurs outside of conscious awareness, and without any intent to mimic or imitate Empirical evidence suggests a bi-directional relationship between nonconscious mimicry on the one hand, and liking, rapport, and affiliation on the other That is, nonconscious mimicry creates affiliation, and affiliation can be ex- pressed through nonconscious mimicry We argue that mimicry played an impor- tant role in human evolution Initially, mimicry may have had survival value by helping humans communicate We propose that the purpose of mimicry has now evolved to serve a social function Nonconscious behavioral mimicry increases af- filiation, which serves to foster relationships with others We review current re- search in light of this proposed framework and suggest future areas of research
