    Donor misreporting:conceptualizing social desirability bias in giving surveys

    Although survey research is one of the most frequently used methods for studying charitable giving, the quality of the data is seldom stated or known. In particular, social desirability bias (SDB) has been found to distort data validity where respondents tend to over-report what is socially desirable and vice versa. We argue that this phenomenon has not been fully understood in the nonprofit context as existing social desirability scales are not appropriate to be used in giving surveys. Thus, this paper is the first to extend understanding of SDB to the nonprofit context and to explore its motivating factors. Based on a multidisciplinary literature review and qualitative interviews with various senior practitioners from the fundraising and marketing research sectors, it is suggested that SDB is a multidimensional construct yielding five dimensions, namely, impression management, self-deception, level of involvement, perceived benefits and social norms. The paper then discusses the implications for nonprofit researchers and concludes with directions for future research

    Ferromagnetic cytocompatible glass‐ceramic porous microspheres for magnetic hyperthermia applications

    Highly porous, ferromagnetic glass-ceramic P40-Fe3O4 microspheres (125–212 ”m) with enhanced cytocompatibility have been manufactured for the first time via a facile, rapid, single-stage flame spheroidization process. Dispersions of Fe3O4 and Ca2Fe2O5 domains (≈10 ”m) embedded within P40 (40P2O5-16CaO-24MgO-20Na2O in mol%) phosphate-based glass matrices show evidence for remanent magnetization (0.2 Am2 kg−1) and provide for controlled induction heating to a constant level of 41.9 °C, making these materials highly appropriate for localized magnetic hyperthermia applications. Complementary, cytocompatibility investigations confirm the suitability of P40-Fe3O4 porous microspheres for biomedical applications. It is suggested that the flame-spheroidization process opens up new opportunities for the development of innovative synergistic biomaterials, toward bone-tissue regenerative applications
