Quaranteens: Prepandemic relationship quality and changes in adolescent internalizing problems during the COVID-19 pandemic

This preregistered longitudinal study examined changes in adolescents' depressive and anxiety symptoms before and during the COVID-19 pandemic using latent additive piece-wise growth models. It also assessed whether support from and conflict with mothers, fathers, siblings, and best friends explained heterogeneity in change patterns. One hundred and ninety-two Dutch adolescents (Mean age: 14.3 years; 68.8% female) completed online biweekly questionnaires for a year (November 2019–October 2020), consisting of a prepandemic, lockdown, and reopening phase. Depressive symptoms increased following the lockdown and decreased upon reopening. Anxiety symptoms showed an immediate decrease followed by a gradual increase in the reopening phase. Prepandemic family and best friend support and conflict did not explain heterogeneity in depressive and anxiety symptoms during the COVID-19 pandemic.     

Identifying the determinants of foreign direct investment: a data-specific model selection approach

In this paper, we examine the potential determinants of foreign direct investment. For this purpose, we apply new exact subset selection procedures, which are based on idealized assumptions, as well as their possibly more plausible empirical counterparts to an international data set to select the optimal set of predictors. Unlike the standard model selection procedures AIC and BIC, which penalize only the number of variables included in a model, and the subset selection procedures RIC and MRIC, which consider also the total number of available candidate variables, our data-specific procedures even take the correlation structure of all candidate variables into account. Our main focus is on a new procedure, which we have designed for situations where some of the potential predictors are certain to be included in the model. For a sample of 73 developing countries, this procedure selects only four variables, namely imports, net income from abroad, gross capital formation, and GDP per capita. An important secondary finding of our study is that the data-specific procedures, which are based on extensive simulations and are therefore very time-consuming, can be approximated reasonably well by the much simpler exact methods.     

小说·性别·历史文化——美国汉学家魏爱莲教授访谈录

《水浒后传》虽然不足以列入一流经典,但在探讨中国小说批评在金圣叹等人影响下是如何形成的这一问题时,此书无疑具有作为例证的价值。《水浒后传》被作者陈忱用来表达对政治的疏离和不满,书中引入了小说可以表达个人感情的观念,这使作者站在时代的前沿。中国妇女文化经历了明末清初以及18世纪末至19世纪末这两个时期的发展,在第二个时期,女性可以是读者、评论者甚至作者。女性读者推动了小说的发展,到《红楼梦》续书时表现尤为突出。各种《红楼梦》续书显示出女性可以是值得尊敬的小说批评家,续书的情节经常回应女性的关切。出版、传教和妇女之间有一定关联。出版文化与妇女文化在19世纪末以前有所发展,中西小说在19世纪都拥有了更多的读者。这一方面是因为中国读者不断增长的兴趣;另一方面是书商们敏锐地意识到小说能带来更多利润。就传教士而言,他们意识到小说能改变读者的观念。
