We investigate state-dependent effects of fiscal multipliers and allow for endogenous sample splitting to determine whether the U.S. economy is in a slack state. When the endogenized slack state is estimated as the period of the unemployment rate higher than about 12%, the estimated cumulative multipliers are significantly larger during slack periods than nonslack periods and are above unity. We also examine the possibility of time-varying regimes of slackness and find that our empirical results are robust under a more flexible framework. Our estimation results point out the importance of the heterogenous effects of fiscal policy and shed light on the prospect of fiscal policy in response to economic shocks from the current COVID-19 pandemic.

This article discusses educational aspects of cross-cultural psychology in relationship to Japanese society. After exploring the present status of cross-cultural psychology in Japan, the paper delineates the factual, theoretical, and methodological implications of cross-cultural psychology for the teaching of psychology in Japanese universities. It is argued that an area approach incorporating comparative research on Japanese society can add context, detail, historical perspective, new methodology, and interdisciplinary richness to classes otherwise relying on traditional journal articles and textbooks of cross-cultural psychology. Such an approach is deemed useful for cross-cultural psychology classes taking place both inside and outside Japan. The article concludes with an annotated bibliography of research on Japanese society.  相似文献

This study identifies perspectives of relationships publics have about countries other than their own and examines whether publics engaged through social media-based public diplomacy programs demonstrate different relationship perspectives. Q methodology and survey research were used to investigate these issues. Data come from South Korean adult internet users, including members of Café USA, an online community run by the U.S. Embassy in Seoul. Three relationship perspectives were identified: outcome-based, sincerity-based, and access-based. Compared with other groups, Café USA members put more emphasis on sincerity in their relationships with the United States. The results of this study indicate that individuals’ subjectivity should be considered as far more contextualized and nuanced than has been the case in previous research on national image or country reputation.  相似文献

A survey of a random sample of licensed social workers in Virginia showed 98.8% had Internet access in either their home or workplace. A comparison of this study with a study conducted in the early 2000s indicated more than 20% difference regarding e-mail communication with clients and Internet use for work-related research. Social workers who actually used the Internet and e-mail tended to expect a future increase in their use, in contrast with nonusers. Stepwise multiple logistic regression analyses found age and type of agency (private/for-profit) as factors negatively related to having Internet access in the workplace, age, and the reason “E-mail is not secure enough” as factors negatively related in the future e-mail communication with clients among current nonusers.  相似文献

Background

Decreased fetal movements are associated with adverse perinatal outcomes, including stillbirth. Delayed maternal visits to a health care provider after perceiving decreased fetal movements are frequently observed in stillbirths. Informing pregnant women of the normal range of fetal movement frequency is essential in their earlier visits in order to prevent stillbirth.

Aim

To investigate the fetal movement frequency in late pregnancy and the effects of associated perinatal factors.

Methods

This prospective multicenter study was conducted in 20 obstetric facilities in our region of Japan. A total of 2337 pregnant women were asked to record the time it took to perceive 10 fetal movements by the modified ‘count to 10’ method every day from 34 weeks of gestation until delivery.

Findings

The 90th percentile of the time for the maternal perception of 10 fetal movements was 18–29 min, with a gradually increasing trend toward the end of pregnancy. The numbers of both pregnant women giving birth after 39 weeks’ gestation and infants with a birth weight exceeding 3000 g were significantly higher in mothers who took ≥30 min to count 10 fetal movements than in those who took <30 min.

Conclusion

The maternal perception time of fetal movements shows a gradually increasing trend within 30 min for 10 fetal movements by the modified ‘count to 10’ method. Informing pregnant women of the normal range of the fetal movement count time will help improve the maternal recognition of decreased fetal movements, which might prevent fetal death in late pregnancy.  相似文献

The importance of listening in the context of English language acquisition is gaining acceptance, but its unique attributes in language performance, while substantively and qualitatively justifiable, are generally not psychometrically defined. This article psychometrically supports listening as a distinct domain among the three other domains of language learning—reading, writing, and speaking—through the analysis of listening data from a large-scale K-12 English language proficiency assessment. Student responses in this study were compared on the basis of cognitive, metacognitive, and other learning strategies between high achieving and low achieving listening groups that were formed using a latent mixture distribution model. Latent mixture distribution and differential items functioning analyses together with classical item analysis were used to substantiate or draw attention to literature findings. The article also highlights the importance of social-interactive items that are inadvertently embedded in an assessment that is primarily created to measure academic language.  相似文献

This study is part of a collaborative project examining the quality of life in Confucian societies in Asia. Our major findings suggest that, when our sixteen specific life domains are grouped into three life spheres, namely, material, post-material, and public, the Japanese people tend to be most satisfied with the post-material sphere of life and least satisfied with the public sphere of life such as the condition of environment and welfare system. In searching the direct, independent effects of demographics, lifestyles, value priorities, and domain assessments on the quality of life, none of the public life domain assessments shows a significant impact on the quality of life, while friendships and spiritual life in the post-material sphere of life are an important determinant. Equally notable is the finding that neither educational attainment nor household income contributes significantly to the experience of subjective well-being. Leading a global lifestyle also affects positively the quality of life. Finally, being married and satisfaction with marital life appear to be powerful and prevalent influence on the quality of life in Japan.

Despite their fear of repercussions on career advancement and gender identity, Korean fathers taking parental leave have continually increased. Why do Korean fathers take parental leave in spite of the risk of being stigmatized as less masculine and less ideal workers? Are they willing to be ‘ideological renegades' to be new involved fathers? In‐depth interviews with fathers who took parental leave provide interesting answers. Overall, taking parental leave does not make fathers become ideological renegades since it is mainly utilized in a manner that accommodates the work devotion schema, deviating from the formal policy objectives. This deviant utilization is encouraged and even valued by organizations. This may be part of a psychological contract between organizations and employees, ensuring that employees are dedicated to their career even during parental leave. Furthermore, beyond the legal eligibility of uptake, informal but powerful ‘organizational eligibility' such as high performance or their contribution to the organization, makes not only the likelihood but also the aftermath of taking up different across fathers. As a result, a hierarchy among fathers with class connotations emerges. This hierarchy among fathers, combined with the traditional gender hierarchy, may reinforce the masculine fabric of ideal workers as the norm.  相似文献

We study one-to-one matching problems and analyze conditions on preference domains that admit the existence of stable and strategy-proof rules. In this context, when a preference domain is unrestricted, it is known that no stable rule is strategy-proof. We introduce the notion of the no-detour condition, and show that under this condition, there is a stable and group strategy-proof rule. In addition, we show that when the men’s preference domain is unrestricted, the no-detour condition is also a necessary condition for the existence of stable and strategy-proof rules. As a result, under the assumption that the men’s preference domain is unrestricted, the following three statements are equivalent: (i) a preference domain satisfies the no-detour condition, (ii) there is a stable and group strategy-proof rule, (iii) there is a stable and strategy-proof rule.  相似文献
