    STEM degree completion and first-generation college students. A cumulative disadvantage approach to the outcomes gap

    STEM majors offer pathways to lucrative careers but are often inac-cessible to first-generation students. Using data from the Education Longitudinal Study, we conducted descriptive statistics, regression analyses, and group comparisons to examine differences between first-generation students and continuing-generation students across STEM degree, non-STEM degree, dropout, and no degree completion. Findings illuminate that generation status is related to STEM completion, but other factors are driving this association; for example, pre-college STEM factors have significant predictive power. Our implications suggest a need to further examine pre-college and transfer pathways to STEM and to explore the limitations of first-generation status as a categorization

    Attitudes Toward and Behavioral Intentions to Adopt Mobile Marketing: Comparisons of Gen Y in the United States, France And China

    The rapid global diffusion of mobile marketing makes it increasingly important to understand cross-Ā­ā€cultural consumer attitudes and behavioral intentions toward mobile marketing as a promotional channel. By building on the previously published research of Altuna and Konuk (2009), this work investigates the attitudes and behavioral intentions toward mobile marketing of Generation Y consumers in the United States, France, and China. Based on this analysis, Chinese Gen Y have the most positive attitude toward mobile marketing, and their overall attitude is significantly more positive than the attitudes of French and American Gen Y groups. While American Gen Y\u27s behavioral intentions are more favorable, their intentions to adopt mobile marketing are not significantly different from the other two groups. For American and French Gen Y, although not for Chinese Gen Y, it appears that positive attitudes toward mobile marketing relate to positive behavioral intentions to adopt mobile marketing

    Financial Planning for College: Parental Preparation and Capital Conversion

    Get PDF
    This study explores the conversion of cultural capital into economic capital, and specifically financial capital in the form of parental financial planning for childrenā€™s college education, including reported financial preparations and savings. Using data from the Education Longitudinal Study (ELS:2002), logistic regression-based analyses of aspects of cultural capital indicated that parental involvement exhibited the most prevalent relationship with financial planning and the amount saved, and that parentsā€™ expectations, but not their aspirations, corresponded to engagement in financial planning. Findings support the conclusion that some parents convert part of their cultural capital to financial capital in preparation for paying for their childā€™s college education, perhaps representing a typically hidden facet of social class reproduction

    Pd/ZnO catalysts for direct CO2 hydrogenation to methanol

    The direct hydrogenation of CO2 into methanol is crucial for providing a means of CO2 fixation and a way to store cleanly produced hydrogen in a more energy-dense and transportable form. Here we have prepared two series of Pd/ZnO catalysts, both by immobilisation of PVA-protected Pd colloids and by Pd impregnation of PdCl2 to investigate structure activity relationships for direct CO2 hydrogenation. Very different performances were found for the different preparation methods, and the Pd loading and pre-reduction of the catalysts were shown to be important factors for optimising methanol yield. The crucial factor for high methanol yield is the formation of a Pdā€“Zn alloy, either during the reaction itself, or better by high temperature pre-reduction. The formation of the alloy greatly reduces CO production by the reverse water gas shift reaction. The catalysts prepared by sol-immobilisation were relatively stable to thermal treatment. In contrast, the impregnated catalysts were much less thermally stable, due to the presence of remnant chloride on the surface of the catalyst, which was absent for the case of sol immobilisation preparation. The results illustrate the importance of controlling the PdZn particle size and its surface structure for the catalysts to achieve high methanol selectivity (60%, the rest being CO) and conversion (11%) at 250 Ā°C and 20 bar. Selectivity for sol-immobilised catalysts decreases from 60% at 3 nm average diameter, to 20% at 7 nm
