正Business ties contribute to the development of a new type of Sino-U.S.great-power relationship By Patrick Mendis U.S.President Barack Obama’s vision for better relations with China is based on a time-tested commercial foundation.To enhance his Asia"pivot"strategy and the TransPacific Partnership(TPP)plan,then Secretary of State Hillary Clinton officially launched the"100,000 Strong"educational exchange initiative for American students to study in China. 相似文献

The real interest rate is a very important variable in the transmission of monetary policy. It features in vast majority of financial and macroeconomic models. Though the theoretical importance of the real interest rate has generated a sizable literature that examines its long-run properties, surprisingly, there does not exist any study that delves into this issue for South Africa. Given this, using quarterly data (1960:Q2-2010:Q4) for South Africa, our paper endeavors to analyze the long-run properties of the ex post real rate by using tests of unit root, cointegration, fractional integration and structural breaks. In addition, we also analyze whether monetary shocks contribute to fluctuations in the real interest rate based on test of structural breaks of the rate of inflation, as well as, Bayesian change point analysis. Based on the tests conducted, we conclude that the South African EPPR can be best viewed as a very persistent but ultimately mean-reverting process. Also, the persistence in the real interest rate can be tentatively considered as a monetary phenomenon. 相似文献

Purpose
Measures of adolescent psychopathy have yet to be examined in offending trajectory studies. This may explain why identifying etiological differences between individuals following high-rate and moderate-rate offending trajectories has remained elusive. The current study used the Psychopathy Checklist: Youth Version (PCL:YV) to examine psychopathic traits and offending trajectories within a sample of incarcerated offenders.Methods
Convictions were measured for Canadian male (n = 243) and female (n = 64) offenders at each year between ages 12 and 28. Semi-parametric group based modeling identified four unique trajectories: adolescence-limited (AL) (27.3% of sample), explosive-onset fast desister (EOFD) (30.6%), high-rate slow desister (HRSD) (14.6%), and high frequency chronic (HFC) (27.5%).Findings
Both a three and a four factor model of psychopathy were tested, and both factor structures were positively and significantly associated with the HRSD and HFC trajectories. Regarding individual factors of psychopathy, the ‘Antisocial’ factor of the PCL:YV was the only individual dimension significantly associated with membership in high-rate compared to moderate-rate offending trajectories.Conclusions
Psychopathic traits appear more commonly present amongst individuals who follow chronic versus moderate offending trajectories. Implications for early intervention and risk management of offenders are discussed. 相似文献874.
Purpose
To examine the persistence of physical aggression in preschoolers and associated correlates (i.e., socio-demographic, socioeconomic, criminality, parenting practices, maternal mental health).Methods
One-year follow-ups are completed with 240 mothers and their preschool children (boys and girls) from the Vancouver Longitudinal Study on the Psychosocial Development of Children. A series of structural equation models are examined.Results
Maternal psychological symptoms, juvenile delinquency, and adult offending are associated with higher levels of physical aggression in their offspring. Children of non-Caucasian mothers and those born outside of North are less physically aggressive. Cultural differences in the correlates of physical aggression were identified.Conclusions
Maternal past delinquency, current adult offending, and mental health are important factors in the development of children’s physical aggression. The findings suggest that there are multiple pathways leading to chronic physical aggression, which may be culturally-based. Cultural differences should be taken into account when developing programs and intervening with families of children with behavioral problems. 相似文献875.

Political science generally treats identities such as ethnicity, religion, and sexuality as “unmoved movers” in the chain of causality. I hypothesize that the growing salience of partisanship and ideology as social identities in the United States, combined with the increasing demographic distinctiveness of the nation's two political coalitions, is leading some Americans to engage in a self-categorization and depersonalization process in which they shift their identities toward the demographic prototypes of their political groups. Analyses of a representative panel data set that tracks identities and political affiliations over a 4-year span confirm that small but significant shares of Americans engage in identity switching regarding ethnicity, religion, sexual orientation, and class that is predicted by partisanship and ideology in their pasts, bringing their identities into alignment with their politics. These findings enrich and complicate our understanding of the relationship between identity and politics and suggest caution in treating identities as unchanging phenomena. 相似文献

We distinguish between (i) voting systems in which voters can rank candidates and (ii) those in which they can grade candidates, using two or more grades. In approval voting, voters can assign two grades only—approve (1) or not approve (0)—to candidates. While two grades rule out a discrepancy between the average-grade winners, who receive the highest average grade, and the superior-grade winners, who receive more superior grades in pairwise comparisons (akin to Condorcet winners), more than two grades allow it. We call this discrepancy between the two kinds of winners the paradox of grading systems, which we illustrate with several examples and whose probability we estimate for sincere and strategic voters through a Monte Carlo simulation. We discuss the tradeoff between (i) allowing more than two grades, but risking the paradox, and (ii) precluding the paradox, but restricting voters to two grades. 相似文献

The New Economic Governance (NEG) in the European Union is a core element of a neoliberal crisis constitutionalism that has to be seen as blatantly deficient when measured with democratic yardsticks. Strongly normative criticism generates important findings, but ignores the economic dimension of damage to democracy. From the perspective of capitalism theory, the NEG can be recognised as a product of a capitalistic land grab (“Landnahme”) of the political field and as a system of institutions whose functional logic corresponds to the imperative of a crisis-ridden economy characterised by the financial markets. In this context, viewpoints are confirmed that regard the integration of the economic causes of blatant deficits of democracy as an essential element of a new type of inclusive democracy project. The work on a new economic democracy as a core element of such a democracy project thus also becomes a desideratum for a public sociology that wishes to contribute evidence-based knowledge to social disputes. 相似文献

There has been a long-standing discussion since the 1980s about the question whether new production models harbor a potential for extended employee participation and involvement, in most cases with disillusioning results. This paper is concerned with so called “agile methods”, which play an important part in the area of knowledge work in the course of the digital transformation. On the basis of two case studies from software development and industrial R&D, the paper examines the concrete implementation of these methods and the employees’ perspective upon them and their consequences. The result is that agile methods present a potential for extended employee participation and involvement; however, the realization of this potential depends on the concrete way how the agile concept of “empowerment” is implemented. 相似文献
