This article considers the immediate forces influencing China’s food system and food security. By immediate is meant events of the reform period, from the late 1970s to 2008. It begins by asking the question that has preoccupied specialists since the publication of Lester Brown’s Who Will Feed China? in 1995: How much arable land does China have? Is that land area sufficient to insure grain sufficiency? To insure food security? The article focuses on the human pressures on the food production environment, and then treats the effects of socioeconomic change: land, air, and water degradation. The core of the article examines six responses of the state to both perceived and actual environmental stressors: policy restricting arable land conversion, China’s one-child policy, investment in irrigation systems, the South–North Water Diversion Project, large-scale afforestation and reforestation campaigns, and the program to convert marginal agricultural lands to forests and grasslands. 相似文献

Much of the literature on welfare dynamics has focused on the effects of recipient characteristics and state‐level characteristics such as welfare benefits and economic conditions; there has been very little analysis on the effects of child support. This paper, using the 1979‐1996 National Longitudinal Survey of Youth, examines whether child support affects the likelihood of leaving and re‐entering welfare. The results indicate that strong child support enforcement is important in helping young mothers exit and stay off welfare. Women with $1000 child support payments in the previous year were 18 percent more likely to exit welfare and 12 percent less likely to re‐enter welfare. Compared with women in states that pursued child support least vigorously, women in states that had passed extensive child support enforcement legislation and that spent more money on child support enforcement were 79 percent more likely to exit welfare and about 60 percent less likely to re‐enter welfare. © 2002 by the Association for Public Policy Analysis and Management. 相似文献

Contact and close‐range gunshot injuries can produce bloodstains on the shooting hand and weapon. In this study, backspatter was analyzed in experimental horizontal pistol shots into blood‐filled sponges. The shooting distances were set between 0 and 45 cm. With increasing shooting distance, there was a significant decrease in the degree of backspatter. Microspatter could be detected on the weapon and shooting hand up to a shooting distance of 40 cm. They were predominantly located on thumb and index finger as well as the radial dorsal aspects of the hand. Fine spray of microspatter combined with elongated droplets in the shape of exclamation marks was found at contact and 2‐cm distance shots. An angular calculation based on the shape of the bloodstains was possible up to a shooting distance of 2 cm. No bloodstains were detected beyond 45 cm. 相似文献

Abstract: Conducted electrical weapons (CEWs) such as the TASER® M‐ and X‐series deliver short high‐voltage, low‐current energy pulses to temporarily paralyze a person by causing electrical interruption of the body’s normal energy pulses. Despite many scientific publications, which classify the health risks of an appropriate use of the TASER device as minor, there still is a continuous uncertainty about possible side effects with human application. Based on a literature search of the National Library of Medicine’s MEDLINE database’s PubMed system of current publications, the following article describes the mechanisms by which the device operates and discusses possible pathophysiological consequences. The majority of current human literature has not found evidence of clinical relevant pathophysiological effects during and after an exposure of professionally applied CEWs. However, to be able to exclude possible health risks, a medical checkup of people who have been exposed to CEWs is essential. 相似文献

A case of unusual postmortem mutilation of a victim's body is presented. After killing his father, the son decapitated his body and dissected the scalp free, forming a mask of the father's head and neck. The young man wore the scalp-mask over his own head to imitate the father. The motive of the murder was revenge, and the postmortem mutilation was the realization of the perpetrator's fantasies, symbolically representing a penalty for the reprehensible past life of his father. 相似文献
