Mismatch of inventory information between the reality and what is on the record of information systems has been generally accepted as inventory inaccuracy. Its financial impacts go beyond the cost of direct inventory loss at each stage of the supply chain. The discrepancy also results in increasing holding and shortage cost because information distortion propagates along the supply chain. With the growing emphasis on responsiveness and cost of inventory, inventory inaccuracy has become a critical hurdle to achieve high performance supply chains. The emergence of RFID technology offers a possible solution to alleviate the growing cost of inventory inaccuracy. However, differs from tangible justification based on shrinkage reduction, adoption of RFID technology has to be justified with improvement in intangible information flow. The objective of this paper is to present a systematic approach with analytical models to quantify the extent of saving from timely information as well as reduction in information distortion and its amplification. With the increasing dynamic and complexity of global supply chain, this paper may shed some new light on framing the discussion of investing in RFID technology. © 2012 Elsevier B.V.

Constrained clustering has been well-studied in the unsupervised learning society. However, how to encode constraints into community structure detection, within complex networks, remains a challenging problem. In this paper, we propose a semi-supervised learning framework for community structure detection. This framework implicitly encodes the must-link and cannot-link constraints by modifying the adjacency matrix of network, which can also be regarded as de-noising the consensus matrix of community structures. Our proposed method gives consideration to both the topology and the functions (background information) of complex network, which enhances the interpretability of the results. The comparisons performed on both the synthetic benchmarks and the real-world networks show that the proposed framework can significantly improve the community detection performance with few constraints, which makes it an attractive methodology in the analysis of complex networks.

For most insurers, traditional methods of controlling health-care demand include deductibles, co-payments, stop-losses, and insurance ceilings. This paper examines the effect of the patient reimbursement method of health insurance (immediate reimbursement or later reimbursement) on individuals' health-care utilization decisions. We find that immediate reimbursement significantly increases the likelihood of patients seeking outpatient treatment in China. We also empirically explore the channels through which immediate reimbursement affects individual's incentives on health-care demand. Copyright © 2010 John Wiley & Sons, Ltd.

Contraception | Year: 2012
Background: In China, contraception is the most commonly used practice adopted by couples seeking to limit their number of children and to determine the time interval between births. Since 1980, the implementation of mandatory contraceptive strategy has reduced the fertility rate. Using large-scale data from national statistics and nationally representative sample surveys, the current study aims to assess Chinese trends in contraceptive use and determinants of choice from 1980 to 2010 among married women and men aged 20-49 years. Study Design: Since 1980, national data on contraceptive methods utilization have been gathered by the National Population and Family Planning Commission of the People's Republic of China (NPFPC). Additionally, data from three roughly representative decennial samples (1988, 1997, 2006) of Chinese women of aged 20 to 57 years have been gathered by the NPFPC through the National Family Planning and Reproductive Health Surveys in China. Results: A relatively stable Chinese mode of contraception has been established and maintained since the 1980s. This is characterized by long-term contraceptive use which is still dominant in current China. In addition, China's total contraceptive prevalence rates remain at the highest level across the globe from 1980 to 2010. However, the overall method composition of contraceptive use within China has changed since the mid-1990s. Over the study period, the prevalence rate of sterilization increased from 30.21% in 1980 to 46.47% of married women of reproductive age (20-49 years) in 1994 and then declined to 31.7% in 2010. At the same time, intrauterine device usage increased (39.83% in 1980 to 48.15% in 2010), as did oral contraception (0.3% in 1980 to 0.98% in 2010) and condom usage (2.35% in 1980 to 9.32% in 2010). The results from the multinomial logit model show that an individual's contraceptive choice depends not only on individual characteristics, including ethnicity, age, education level, household registration, region, number of living children and sex of the last living child, but also on the strength of family planning policies. A positive coefficient indicates that the looser the strength of family planning policies is, the more likely the individual is to choose condoms or another short-term contraceptive method. Conclusions: Long-term contraceptive use is still dominant in China. In fact, over the 30-year period (1980-2010) and in comparative world perspective, China continues to have the highest total contraceptive prevalence rate. Additionally, an individual's contraceptive choice is jointly influenced by the strength of family planning policies and individual characteristics. © 2012 Elsevier Inc.

Contraception | Year: 2012
Background: China launched a nationwide family planning program offering birth control methods and family planning services in the 1970s. Promotion of the widespread use of long-term contraceptive methods has been one of the program's core strategies. This paper reviews the history of China's Family Planning Program at the national level from 1970 to 2010. Special attention is paid to the history of contraception policy. Study Design: This study provides an overview of the last four decades of the Chinese Family Planning Program. Programmatic goals are highlighted during different time periods, with special attention being paid to the role of contraceptive use and the history of contraceptive policy. Results: The Chinese Family Planning Program has experienced several transitions. It has evolved from the 1970s period of moderate policy, represented by wan, xi, shao (late marriage and childbearing, birth spacing and limited fertility), through the strict one-child policy of 1979 to the early 1990s. From the mid-1990s to the present, a relatively lenient policy has been in force, characterized by client-centered informed choice. Conclusions: The success of the Chinese Family Planning Program has long been heavily dependent on policies advocated by the central government, including programs promoting contraception to reduce fertility rates. The Program also depended on a logistical support system, including organizational safeguards and free provision of contraception and family planning services. © 2012 Elsevier Inc.
