C2C交易风险与诚信管理机制分析

本文就c2c交易中的两种主要的风险从经济学的角度分析了它们影响交易的程度,指出技术风险相对来说是一个外生变量,而交易过程风险则是内生变量。并据此提出要减少交易风险,建立c2c电子商务市场上参与方的信任关系,就要设立合理的诚信管理机制。其中阐明了第三方信任机构主导型诚信管理机制与参与者自我主导型管理机制各有优势,将二者结合起来才是最优的选择,并以我国c2c网站的诚信管理机制应用举例说明了诚信管理机制的运用。

Agenda for a new monetary reform

The thrust of this article is that once more the time has come for a broad debate on domestic and international monetary order and on the role and the rules governing the functioning of financial markets in the modern market economy. We have to define an agenda and seek a consensus for a new monetary reform that will take into account both the positive and negative lessons learned from more than twenty years of experience with liberalization, deregulation and privatization in the financial sector, with flexible exchange rates and international monetary instability. In today's world economy there is an especially dangerous contrast between, on the one hand virtually total globalization of financial markets, and the fixation of monetary policy on narrow national objectives on the other hand. The article lists eight major items that ought to be considered in this debate: (1) the adoption of common rules necessary in a global market economy, (2) the need to return to a true international monetary order, (3) redefining and strengthening the role of central banks, (4) examining the dangers of a primarily short-term finance driven globalization, (5) extending the scope of the concept of price instability beyond the domestic price index, (6) dealing with the problem of artificial risk creation in financial markets and establish a more equitable distribution of the costs of risks, (7) reconsider the current distribution between earning on financial assets and other income and counteract the deflationary bias in the current system, (8) redefine monetary and financial order that is compatible with modern information technologies, rather than lagging behind the information revolution. The article does not offer set solutions for all these issues. Its conclusion is, however, that without such a debate and a consensus on a balanced new approach, there is a real threat of a backlash, the threat of losing the advantages of liberalization and globalization and of a return to increased monetary and economic nationalism and to excessive government intervention and control.     

2型糖尿病社区管理的效果分析

为探究2型糖尿病患者社区管理的效果，随机选取2个社区卫生服务站2型糖尿病患者91例为社区管理组，同时随机选取黄石理工学院附属医院专科门诊2型糖尿病患者86例为医院对照组。2年后比较分析2组患者的体重指数（BMI）、空腹血糖（FPG）、餐后2h血糖（2hPG）及糖化血红蛋白（HbAlC）等指标。结果为：社区管理组患者的各项指标明显优于医院对照组，且2组指标存在显著性差异（P〈0．01）。规范的社区管理可提高2型糖尿病的治疗效果。     

Netweaving alternative futures: Information technocracy or communicative community?

The metaphor of networking is widely used to describe how the emerging communications and information technologies are supposedly overcoming the tyranny of distance. In this case it has positive overtones, as if the barriers are coming down for a more open exchange among different people separated by distance and culture, making for some kind of better world, but is such technological optimism justified? Also, is it deliberate promotion on the part of eager technocrats whose vested interests have been favoured often ahead of a concern for the human condition? Here, an alternative metaphor, netweaving, is used in order to examine the apparent tensions and paradoxes surrounding the introduction of new communications and information technologies. Especially it will investigate the complex associations between apparently opposing dimensions within three layers of the social fabric: globalisation/localisation; centralisation/decentralisation; and standardisation/diversification. A futures studies assessment is used to anticipate alternative scenarios for the impact on the social fabric by the emerging technologies a generation from now, in 2020.     

Global communication and pluralization of identities

As a burning issue of the modern era, national identity is currently subjected to two main contradictory forces. Globalization processes from above and localization forces from below are simultaneously integrating and fragmenting national identities. This essay examines the negotiation of cultural identities in light of the historical transitions from premodern to modern and postmodern modalities and sensibilities. The essay argues that the commodity fetishism of the marketplace is as important an element in contemporary cultural formations as the identity fetishism of militant social movements. Both phenomena are fostered by global communication processes in which identity formations increasingly depend on commodification and distantiation. While global advertising focuses on consumption to frame status identities, mediated communication appeals to primordial myths to structure civic and political identities within imagined communities. The two phenomena must be considered as dialectical twins in contemporary motivation, legitimation, and hegemonic crises.

Economic benefits of adequate molecular monitoring in patients with chronic myelogenous leukemia

Objective:

Molecular monitoring of chronic myeloid leukemia (CML) has been associated with improved clinical outcomes during tyrosine kinase inhibitor therapy (TKI), yet recent studies have demonstrated its use is far below published guidelines. This study sought to determine frequencies of molecular monitoring and its impact on resource utilization and medical costs.

Methods:

A retrospective US claims administrative database (IMS LifeLink Health Plan Claims and Truven Health Analytics MarketScan databases, 11/2007–06/2012) was used to analyze the economic impact of qPCR testing in CML patients on first-line TKIs during the initial 12-months of treatment.

Results:

One thousand two hundred and five adult CML patients met the sample selection criteria. Among these, 41.0% had no qPCR tests, 31.9% had 1–2 tests, and 27.1% had 3–4 tests; 88.9% were initiated on imatinib; 47.7% were female. Patients in the 3–4 tests cohort incurred 44% (p?p?=?0.005) lower for the 3–4 tests cohort than the 0-tests cohort. Adjusted progression-related IP cost was $4132 (p?=?0.013) lower for the 3–4 tests cohort than the 0-tests cohort. Adjusted medical service cost was $5997 (p?=?0.049) lower for the 3–4 tests cohort than the 0-tests cohort.

Limitations:

Claims databases did not include information on the primary cause of hospitalizations.

Conclusions:

Among CML patients in two large claims databases, nearly three-quarters did not receive adequate molecular monitoring per published guidelines. Those who were more frequently monitored incurred lower medical service costs, with the majority of the difference in costs being related to disease progression. These findings underscore the clinical and economic values of molecular monitoring in CML.     

Tourism and information technologies

The apparent mismatch between tourism and technology can be reconciled by a closer examination of the tourism production system (TPS) and the technologies likely to affect it. It is found that a whole system of information technologies (SIT) is being adopted by all segments of the travel industry. The SIT, however, will not attack the human content of tourism. Rather, it will affect the core information-intensive areas of management, organization, product blending and packaging, marketing, distribution and industry linkages. Factors likely to affect the diffusion of the SIT in tourism are identified. Implications of technology adoption for future organization, management, and distribution of tourism services are drawn out.
