智能凝胶GD-1混堵技术在靖边气田的应用

靖边气田钻井过程中发生井漏,采用常规堵漏技术(桥塞堵漏、水泥浆堵漏)常堵漏不彻底、容易出现井漏反复等井下复杂情况。基于常规堵漏方法,引进智能凝胶GD-1混堵技术在靖边气田南部黄土表层、刘家沟组裂缝地层应用,取得了良好的防漏、堵漏效果:提高了堵漏成功率,减小堵漏反复性,二次堵漏的几率明显降低。     

Quality management,environmental management maturity,green supply chain practices and green performance of Brazilian companies with ISO 14001 certification: Direct and indirect effects

This study aims to test a new conceptual model based on the relationship between quality management (QM), environmental management maturity (EMM), adoption of external practices of green supply chain management (GSCM) (green purchasing and collaboration with customers) and green performance (GP) with data from 95 Brazilian firms with ISO 14001. To our knowledge, such links and relationships are not simultaneously identified and tested in the literature. The results indicate the validation of all of the research hypotheses. This paper highlights that an improvement in green performance will require attention to quality management, environmental management maturity, and green supply chain.     

Reasserting Institutionalist Insights on the Good Society: 30 Years After Petr’s Call for a Mixed Economy

In this research note, I revisit the issues raised by Jerry Petr (1987) in “The Nature and Necessity of the Mixed Economy.” The institutionalist mixed economy is still a sound model for the good society. However, Western industrialized countries have been losing ground on the goals of the mixed economy. The struggle to defend pragmatism over ideological attachment to neoliberalism, has evolved into a distributional struggle that cannot be resolved without institutional change.

混业经营发展趋势对我国保险业的影响

我国加入WTO后，金融行业已全部对外开放，通过混业经营实现整个金融行业实力的提升成为应对国外资本入侵的一种重要途径。保险行业作为最早对外资开放的行业之一，如何面对外来竞争，如何通过加强与其他行业的合作来增强自身实力都成了很现实的问题。     

多气源掺混作为城市燃气过渡气源在实际中的应用

为了解决青岛市煤气供需不平衡的矛盾,为引进天然气作好前期准备,我公司将多种气源(焦炉煤气、焦炉烟道气、空气、全水煤气、半水煤气、液化石油气、石化厂净化干气)均匀掺混,掺混后的煤气热值控制在15 675～17000 kJ/m3(适合青岛市燃具),含氧量不大于4.0%.通过实际应用,多气源掺混供气,满足了供气需要,可以作为过渡气源满足城市燃气转换成天然气的需要.     

我国中小商业银行多元化经营的效应分析

本文利用超越对数函数和对我国中小银行1987～2004年间多元化经营行为的经济效应进行了实证分析，并从存量和流量角度探究了当前多元化经营的发展水平，提出了我国中小银行多元化经营的行为动因与逻辑。研究发现，我国中小银行存在明显的范围经济，但长期以来多元化经营发展缓慢，现行金融制度环境和中小银行经营机制缺陷是根本原因，外部市场环境约束影响了中小银行的多元化经营，内部风险控制不足制约了多元化的发展动力，过分追求规模扩张影响了多元化经营效果，市场定位模糊导致多元化经营的盲从，因此，要提升中小银行多元化经营水平，必须从外部金融制度和自身经营机制入手。     

国际黄金市场发展状况及其趋势分析

在新的国际货币体系下，黄金的货币性虽然被取消，但由于黄金本身所拥有的保值性、安全性、流动性等属性，使其最根本的金融属性并没有降低。全世界40多个大小不一的黄金市场作为金融市场的构成部分，近10年来有了更快的发展。分析各主要黄金市场发展的现状，研究其发展趋势，对于研究其未来的发展路径以及对金融市场的作用具有相当重要的意义。

A New Internet Driven Internationalisation Framework

This paper aims to offer a new Internet driven theoretical framework that explains how a successful internationalisation process may be developed and identifies the strategic dimensions that influence the key decisions in an interrelated, performance-associated way. The extant literature is examined in international marketing, international entrepreneurship and Internet marketing and a comprehensive strategic analysis is conducted of a successful individual services business: ING Direct. It is shown how strategic constructs and risk constructs drive the internationalisation process in an interrelated and performance-associated way. In the framework, the firm's target is to take advantage of an opportunity by obtaining a sustainable competitive advantage while attenuating international risk. Entry mode and country selection are strategic decisions interrelated mutually and with other strategic choices and with performance; this is why an analysis with ceteris paribus statements or episodic analysis may lead to the wrong conclusions.
