Promoting Constructive Conflict from a Conflict Transformation Perspective: The Case of Community-Based Collaboration in Korea

ABSTRACT

This article focuses on developing constructive conflict management in community-based collaborations for macro social workers. Using a conflict transformation perspective as a conceptual framework, we identified significant factors and their dynamic relationships in promoting constructive conflict in the context of 5 community-based collaborations in Korea. Hierarchical multiple regression analyses revealed that responsive coordination was a strong predictor of increased perceptions of constructive conflict. Further, a multiple mediator model indicated that open communication was indirectly associated with perceived constructive conflict by enhancing both equal decision-making and responsive coordination. We conclude by highlighting practical implications of our study.     

论张爱玲小说的心理描写及文学史意义

张爱玲小说的心理描写特点在于：既通过传统手段表现人物的心理，又通过现代手法揭示人物的无意识；既纵向表现人物的心理流程，又通过参差对照的手法横向表现人物的心理变化；既描绘人物的种种变态心理，又刻画人物的性格分裂。其文学史意义在于：丰富了表现人物心理的手法．揭示了人性之恶和人的生存困境，透视出传统中国向现代社会转型过程中人所背负的沉重精神负荷。     

ON ENDOGENOUS BUSINESS CYCLES UNDER INCREASING RETURNS TO VARIETY AND SECTOR‐SPECIFIC EXTERNALITY

We examine the theoretical as well as quantitative interrelations between endogenous business cycles, increasing returns to product variety and sector‐specific productive externalities within a two‐sector real business cycle model. In a calibrated version of our benchmark closed‐economy setting, the threshold level of investment externalities needed for equilibrium indeterminacy is found to be monotonically increasing in the degree of market competitiveness. We also study the model's local stability properties (i) when the parameters that govern the level of intermediate‐good producers' market power and the strength of variety effects are disentangled; and (ii) in the context of a small open economy.

Efficient sequential estimation in a markov branching process with immigration

Sequential estimation of parameters In a continuous time Markov branching process with Immigration with split rate λ₁ Immigration rate λ₂, offspring distribution {p₁j≥O) and Immigration distribution {p₂j≥l} is considered. A sequential version of the Cramér-Rao type information inequality is derived which gives a lower bound on the variances of unbiased estimators for any function of these parameters. Attaining the lower bounds depends on whether the sampling plan or stopping rule S, the estimator f, and the parametric function g = E(f) are efficient. All efficient triples (S,f,g) are characterized; It Is shown that for i = 1,2, only linear combinations of λ_ip_{ij j}'s or their ratios are efficiently estimable. Applications to a Yule process, a linear birth and death process with immigration and an M/M/∞ queue are also considered     

Smoothing Spline Estimation for Partially Linear Single-index Models

In this article, the partially linear single-index models are discussed based on smoothing spline and average derivative estimation method. This proposed technique consists of two stages: one is to estimate the vector parameter in the linear part using the smoothing cubic spline method, simultaneously, obtaining the estimator of unknown single-index function; the other is to estimate the single-index coefficients in the single-index part by the using average derivative estimator procedure. Some simulated and real examples are presented to illustrate the performance of this method.     

SECTORAL COMPOSITION OF GOVERNMENT SPENDING AND MACROECONOMIC (IN)STABILITY

This article examines the quantitative interrelations between sectoral composition of public spending and equilibrium (in)determinacy in a two‐sector real business cycle model with positive productive externalities in investment. When government purchases of consumption and investment goods are set as constant fractions of their respective sectoral output, we show that the public‐consumption share plays no role in the model's local dynamics, and that a sufficiently high public‐investment share can stabilize the economy against endogenous belief‐driven cyclical fluctuations. When each type of government spending is postulated as a constant proportion of the economy's total output, we find that there exists a trade‐off between public consumption versus investment expenditures to yield saddle‐path stability and equilibrium uniqueness.

Planned Happenstance Skills and Occupational Identity Status in High School Students

This study investigated how the 5 components of planned happenstance skills are related to adolescents' occupational identity statuses. A canonical correlation analysis was performed with a sample of 370 high school students in South Korea. The results indicated that higher identity statuses (i.e., achievement and moratorium statuses) were significantly related to the 5 components of planned happenstance skills, whereas lower identity statuses (i.e., foreclosure and diffusion statuses) were not significantly related to the 5 components of planned happenstance skills. In addition, the results of the mediation analysis indicated that the transition from moratorium to achievement status was positively mediated by 3 components of planned happenstance skills: optimism, persistence, and risk taking.
