核心型钢混凝土柱截面非线性分析及抗震设计研究

在型钢混凝土结构基础上提出核心型钢混凝土结构，并对核心型钢混凝土结构研究意义进行概要分析。采用C8I公司通用程序Section Build日-8对56个核心型钢混凝土柱试件进行截面受力性能全过程非线性分析，得到各试件的弯矩一轴力相关曲线（M—N曲线）、弯矩一曲率曲线（M-φ曲线）及弯矩-轴力-曲率曲线（M—N-φ曲线）。结合核心型钢混凝土柱截面全过程非线性分析结果，对核心型钢柱截面曲率延性系数进行分析，并着重考察核心混凝土柱中核心型钢的截面高度、配钢率、型钢截面形式及柱轴压比等主要参数对柱受力性能的影响。研究结果表明，核心型钢能有效改善核心型钢混凝土延性，核心型钢混凝土柱轴压比限值相对钢筋混凝土柱可以明显提高。     

基于经济博弈的供应链利润分配机制研究

仅以合作关系作为供应链利润分配机制是与共享原则相悖的，且也无法实现。基于合作利润分配机制应包括的结构要素和运行要素之间的辩证关系，建立了一厂一商的供应链合作利润分配机制的数学模型。通过对该模型的求解，确定了厂商和渠道利润的数学表达式，定量描述了机制结构要素与运行要素之间的“硬件”与“软件”关系，并对它们的变化区域与对各决策变量及利润的影响程度进行了深入的分析，对现行返利系数的应用进行了讨论：构造出了一种较为有效的供应链合作利润分配机制。

Homer Sarasohn and American Involvement in the Evolution of Quality Management in Japan, 1945–1950

The history of Quality Management, and of the role of Statistics in Quality Management, is inextricably bound to the reconstruction of Japan immediately following the Second World War, and then to developments in the United States over three decades later. Even though these periods are, in societal history, just moments ago, yet there is profound lack of agreement about what was actually done, and who should be recognized for their contributions. This paper draws on historical materials recently made publicly available in order to clarify what actually took place between 1946 and 1950, and in particular the contribution of a remarkable engineer, Homer Sarasohn.     

Behavioural Finance: A Review and Synthesis

I provide a synthesis of the Behavioural finance literature over the past two decades. I review the literature in three parts, namely, (i) empirical and theoretical analyses of patterns in the cross‐section of average stock returns, (ii) studies on trading activity, and (iii) research in corporate finance. Behavioural finance is an exciting new field because it presents a number of normative implications for both individual investors and CEOs. The papers reviewed here allow us to learn more about these specific implications.

Estimating time series and cross section tourism demand models: Mainland United States to Hawaii data

A study of factors affecting the number of visitors to Hawaii during the period 1993–2007 prompted by an observed waning of the U. S. mainland to Hawaii visitor market was conducted. Both time series and cross section analyses revealed that Log Gross State Product, Log Chained Airfare and Log Distance to Orlando, Florida were the most important predictor variables. A mixed model which modeled Log Chained Gross State Product, Log Chained Airfare, two recessions plus the September 11, 2001 effect in addition to other fixed effects and random state effects was used. Cross section (spatial) airfare elasticities on an annual basis were high and growing over time, but those estimated from the time series analysis (temporal) were much lower. Elasticities derived from Gross State Product were moderately high and very stable over time. To counteract the distance effect, stopovers in existing mainland resort cities when en route to Hawaii and other promotions to develop a stronger presence of a Hawaii image were recommended.
