“一带一路”背景下重庆开展对欧贸易的国际法保障

重庆是中国内陆最早开通中欧班列的城市,也是国际贸易陆海新通道的枢纽.自"一带一路"倡议提出以来,重庆对欧贸易建设取得了新成绩,同时也暴露出部分问题.中欧班列运行效率有待提升,本地企业在对外贸易中面临贸易保护主义和贸易壁垒.国际法可以为重庆开展对欧贸易提供坚实的基础,我国应当在"一带一路"框架下推进贸易规则与交通运输规则法制化,以国际法固化双方权利义务,保护各方利益.重庆应当依托"一带一路"倡议,建设好中欧班列和陆海新通道的交通枢纽;同时,根据本地企业自身特点找出一条合适的发展道路,提升重庆和中国的国际影响力,促进"一带一路"建设.     

Interfamily economic exchange: A function of culture or economics?

This study explores differences in inter-household exchange of goods and services in Anglo- and Mexican-American families controlling for income level and for ethnicity. The extent of such exchange, its perceived importance to the family's quality of life, satisfaction with the exchange, and the relation of persons in the exchange process are examined. Significant differences are found more often between higher income Anglo- and Mexican-Americans than between low-income families, both in the family providing goods and services for others and in the receipt of them. Higher income Mexican-American families are more likely than their Anglo- counterparts to exchange with relatives. Ethnic effects are more prevalent in higher income households than in low-income households. Economic effects are more predominant than ethnic effects.This study contributes to interregional Agricultural Experiment Station Research Project NC-128, Quality of Life as Influenced by Area of Residence. Cooperating states: Arizona, California, Colorado, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, Nevada, Ohio, Texas.Flora L. Williams' current research interests include income adequacy, financial problems, and indicators of change in economic well-being.

Origins and destinies: Immigration to the United States since World War II

Contemporary immigration to the United States and the formation of new ethnic groups are the complex and unintended social consequences of the expansion of the nation to its post-World War II position of global hegemony. Immigrant communities in the United States today are related to a history of American military, political, economic, and cultural involvement and intervention in the sending countries, especially in Asia and the Caribbean Basin, and to the linkages that are formed in the process that open a variety of legal and illegal migration pathways. The 19.8 million foreign-born persons counted in the 1990 U.S. census formed the largest immigrant population in the world, though in relative terms, only 7.9% of the U.S. population was foreign-born, a lower proportion than earlier in this century. Today's immigrants are extraordinarily diverse, a reflection of polar-opposite types of migrations embedded in very different historical and structural contexts. Also, unlike the expanding economy that absorbed earlier flows from Europe, since the 1970s new immigrants have entered an hourglass economy with reduced opportunities for social mobility, particularly among the less educated, and new waves of refugees have entered a welfare state with expanded opportunities for public assistance. This paper seeks to make sense of the new diversity. A typology of contemporary immigrants is presented, and their patterns of settlement, their distinctive social and economic characteristics compared to major native-born racial-ethnic groups, and their different modes of incorporation in—and consequences for—American society are considered.

Coherent decision analysis with inseparable probabilities and utilities

This article explores the extent to which a decision maker's probabilities can be measured separately from his/her utilities by observing his/her acceptance of small monetary gambles. Only a partial separation is achieved: the acceptable gambles are partitioned into a set of belief gambles, which reveals probabilities distorted by marginal utilities for money, and a set of preference gambles, which reveals utilities reciprocally distorted by marginal utilities for money. However, the information in these gambles still enables us to solve the decision maker's problem: his/her utility-maximizing decision is the one that avoids arbitrage (i.e., incoherence or Dutch books).     

1997早稻长秧龄旱育“壮杆足穗”栽培技术

本文对早稻长秧龄旱育“壮杆足穗”栽培技术进行了概括和论证：“壮苗”是壮杆足穗的基础;“足穗”是决定高产的第一因素;“壮杆”是高产的重要保证：“增粒壮籽”是壮秆足穗的最终的目标。     

小麦新品种“绵阳26”主要性状与产量的关系

对45个试验点的资料分析,多抗、丰产、优质、广适小麦新品种绵阳26的主要性状有效穗x1、穗粒数x2和千粒x3、单穗重x4与产量y的回归方程为：y＝－614．8425＋9.8683x1＋7.3223x2＋10．5315x3＋22．5748x4。经偏回归和偏相关分析,产量构成因素中,千粒重、有效穗对绵阳26产量的贡献和影响最大（b'3＝1．7435,b'1＝1．5372,R3y.＝0．7983,R1y＝0．6991）。在现有产量的基础上稳定千粒重,主攻穗数和穗粒数,是发挥绵阳26高产潜力的决定因素。

受控核聚变的一种新途径──低能注入式磁盖势阱约束法受控核聚变

提出了磁盖势阱（ＭＬＰＷ）一种静电装置,该装置是在球形静电势阱的外围加上磁盖而构成的,可用于受控核聚变．通过建立磁盖势阱中带电粒子的运动方程并取单粒子谐振子近似以及运用自洽场的统计方法,球形聚变炉内大量带电粒子的集体行为被计算机所研究和模拟．由于使用了电场与磁场的联合约束,与单独的磁约束或惯性约束受控核聚变相比,所需达到的技术指标将有所改善,工程技术上的难度也会有所降低
