Temporary Loan Limits as a Natural Experiment in Federal Housing Administration Insurance

The Economic Stimulus Act of 2008 dramatically but temporarily increased the mortgage loan amount eligible for insurance through the Federal Housing Administration (FHA). We use the implementation and expiration of these loan limits as a source of exogenous variation in the availability of FHA insurance to measure the impact on the overall mortgage market and conventional lending. We find that the introduction of higher loan limits increased the number of loan originations, but that the expiration of those loan limits roughly 6 years later did not significantly decrease affected loan originations. The substitution between loan products and small net impact on the overall mortgage market when the ESA loan limits expired may be explained by the return of a stronger conventional lending industry than existed during the housing crisis.

论“枫桥经验”与社区警务创新发展

从实践层面看,“枫桥经验”的基本内涵及其具体做法,与英、美等西方国家的社区警务不谋而合、各具特色。“枫桥经验”具有社区警务的典型性、特色性、原创性、先进性,是中国特色社区警务的典型代表。是社区警务的“东方模式”。构建社会主义和谐社会、农村新一轮改革发展、学习实践科学发展观、社会治安阶段性特征、警务变革发展趋势等,对社区警务建设提出了新要求。要坚持并发展“枫桥经验”,把群众的呼声作为第一信号,以构建和谐警民关系为支撑,以情报信息为引领,以推进城乡警务一体化为重点,以构建和谐社区为目标。以提高社区民警的素质和能力为保障,主动顺应警务变革的新潮流,不断推动社区警务的创新发展。     

网络言语特征识别

网络语言具有口头语言的一般特征,言语人通过键盘录入文字、传输文字信息、阅读文字内容的方式交流,是一种文字化的语言。对网络语言这样一种口语化的书面语言进行言语识别,主要是针对网络书面言语材料进行的特征识别。只要网络对话内容比较丰富,我们就可以通过网络言语特征识别确定说话者的年龄、职业、文化程度及生活地域等。     

间接ELISA检测鸡大肠埃希氏菌菌毛抗体方法的建立

用大肠埃希氏菌O1、O2、O3、O78和O89株制备ELISA抗原,与抗鸡Ig单抗1B7酶结合物建立了检测鸡血清抗体水平的间接ELISA方法.经交叉试验、阻断试验、重复性试验等表明该方法重复性好、特异性强、灵敏度高;确立了将鸡血清100倍稀释检测ELISA效价(ET)的回归方法y=2.453+0.131x(P＞0.05),可用于定量测定.用IH与ELISA方法的比较试验表明,ELISA法比IH法敏感性高4-100倍.     

Explicating Acculturation Strategies among Asian American Youth: Subtypes and Correlates across Filipino and Korean Americans

Acculturation strategy, a varying combination of heritage and mainstream cultural orientations and one of the significant determinants of youth development, has been understudied with Asian American youth and particularly at a subgroup-specific level. This study used person-oriented latent profile analysis (LPA) to identify acculturation strategy subtypes among Filipino American and Korean American adolescents living in the Midwest. Associations between the subtypes and numerous correlates including demographics, family process and youth outcomes were also examined. Using large scale survey data (N?=?1580; 379 Filipino American youth and 377 parents, and 410 Korean American youth and 414 parents; M_AGE of youth?=?15.01), the study found three acculturation subtypes for Filipino American youth: High Assimilation with Ethnic Identity, Integrated Bicultural with Strongest Ethnic Identity, and Modest Bicultural with Strong Ethnic Identity; and three acculturation subtypes for Korean American youth: Separation, Integrated Bicultural, and Modest Bicultural with Strong Ethnic Identity. Both Filipino American and Korean American youth exhibited immersion in the host culture while retaining a strong heritage identity. Although bicultural strategies appear most favorable, the results varied by gender and ethnicity, e.g., integrated bicultural Filipino Americans, comprised of more girls, might do well at school but were at risk of poor mental health. Korean American separation, comprised of more boys, demonstrated a small but significant risk in family process and substance use behaviors that merits in-depth examination. The findings deepen the understanding of heterogeneous acculturation strategies among Asian American youth and provide implications for future research.     

Democratization and women’s representation in presidential cabinets: evidence from East and Southeast Asia

This article examines patterns of women’s cabinet representation across all presidential democracies in East and Southeast Asia since democratization. It demonstrates how the choice of female ministers differs across career backgrounds in presidential systems and further examines why young presidential systems in Asia are conducive to women’s access to ministerial power through professional career tracks. We argue that despite women’s successful performance in national legislative elections, women have been restricted to access the power resources necessary to target other political goals, such as cabinet positions, whereas democratic transition has provided broader avenues for women to emerge as professionals outside party politics. By analyzing original data on female ministers in East and Southeast Asia, the study finds that the share of women among professional ministers has increased over time, but women’s share among political ministers has not changed significantly. Additionally, the different qualifications of female politicians and professionals also make them eligible for appointment to different types of policy areas in terms of prestige and gender. Our analysis suggests that women’s cabinet representation has improved overall since democratic transition in Asia, but this improvement disguises contrasting outcomes in women’s cabinet status according to their career backgrounds.
