Are environmental attitudes influenced by survey context? An investigation of the context dependency of the New Ecological Paradigm (NEP) Scale

General environmental attitudes are often measured with questions added to surveys about specific environmental or non-environmental issues. Using results from a large-scale national survey on the protection of threatened and endangered marine species, we examine whether the context of the survey in which New Ecological Paradigm (NEP) Scale items are asked influence measured environmental concern. In this application the role that specific threatened or endangered species play in affecting responses to NEP Scale items is explored using a combination of non-parametric and parametric approaches. The results in this case suggest that context does influence stated general environmental attitudes, though the effects of context differ across NEP items.     

Does higher education expansion promote educational homogamy? Evidence from married couples of the post-80s generation in Shanghai,China

The expansion of higher education witnessed in many societies influences the pattern of educational assortative mating. Structural transition theory predicts growing educational homogamy due to increasing preference for highly-educated partners who become more widely available. In contrast, social closure theory suggests depressed educational homogamy because the inflation of the education elite circle fosters the openness of marriage market, reducing the preference for a highly-educated mate and increasing the penetrability across social-status boundaries. Capitalizing the survey data that are representative of the post-80s one-child generation collected in Shanghai, China, we test the hypotheses derived from the two theories. Empirical results suggest that, with increasing availability of highly educated individuals, the extent of educational homogamy by birth cohort reveals a U-shaped pattern. This U-shaped pattern demonstrates increasing levels of educational homogamy and lends support to structural transition theory.
