Geographies of identity theft in the U.S.: understanding spatial and demographic patterns, 2002–2006
Identity theft is among the fastest growing white-collar crimes in the United States, although official recognition of it
as a criminal act is a relatively recent development. Utilizing theoretical framework established in crime geography, GIS
mapping and spatial statistics are employed to conduct a spatial analysis of identity theft in the U.S. from 2002 to 2006.
Distinct regional variations, such as high rates in the western and southwestern states, and low rates in New England and
the central plains states, are identified for identity theft. Significant spatial patterns of identity theft victims alongside
social demographic variables are also revealed in order to better understand the regional patterns that may suggest underlying
social causes contributing to identity theft. Potential social variables, such as race/ethnicity and urban–rural populations,
are shown to have similar patterns that may be directly associated with U.S. identity theft victims. 相似文献

黔湘渝毗邻区南华纪“大塘坡式”锰矿床,近年被认为是一种新的锰矿床类型,即Rodinia超大陆裂解背景下的古天然气渗漏沉积型锰矿床(周琦等,2007,2008,2012)。随着Rodinia超大陆裂解,南华裂谷盆地(I级)的进一步发展,其间的松桃~古丈断陷盆地(Ⅲ级)成为武陵次级裂谷盆地(Ⅱ级)的裂陷中心,锰矿成矿作用强烈,形成的锰矿资源量巨大(安正泽等,2014;杜光映等,2013;侯兵德,2011;杨胜堂等,2013;张遂等,2015),已成为世界级锰矿资源富集区之一。黔东西溪堡-寨英南华纪早期成锰盆地系松桃~古丈断陷盆地(Ⅲ级)中圈定的若干Ⅳ级断陷盆地之一。目前,该盆地北东端已发现西溪堡(203Mt)和桃子坪(106Mt)两个超大型锰矿床,南西端经初步钻探工程验证,已证明预测的正确性,发现了厚1.14~3.14m的锰矿体。 相似文献

Development of a SCAR marker for male gametophyte of Gracilariopsis lemaneiformis based on AFLP technique 总被引:1,自引:0,他引:1
The red alga Gracilariopsis lemaneiformis (Bory) is an economically valuable macroalgae. As a means to identify the sex of immature Gracilariopsis lemaneiformis, the amplified fragment length polymorphism (AFLP) technique was used to search for possible sex- or phase-related markers in male gametophytes, female gametophytes, and tetrasporophytes, respectively. Seven AFLP selective amplification primers were used in this study. The primer combination E-TG/M-CCA detected a specific band linked to male gametophytes. The DNA fragment was recovered and a 402-bp fragment was sequenced. However, no DNA sequence match was found in public databases. Sequence characterized amplified region (SCAR) primers were designed from the sequence to test the repeatability of the relationship to the sex, using 69 male gametophytes, 139 female gametophytes, and 47 tetrasporophytes. The test results demonstrate a good linkage and repeatability of the SCAR marker to sex. The SCAR primers developed in this study could reduce the time required for sex identification of Gracilariopsis lemaneiformis by four to six months. This can reduce both the time investment and number of specimens required in breeding experiments. 相似文献

Owing to the fact that the wind speed and direction of typhoon vary rapidly with time and space in typhoon fetch; the nearer to the typhoon eye the greater the wind velocity, and the shorter the wind fetch the smaller the wind time,as a result,the more difficult for the wind wave to fully grow. Hence.in typhoon wave numerical calculation it is impossible to use the model for a fully grown wave spectrum. Lately, the author et at. presented a CHGS method for numerical forecasting of typhoon waves, where a model for the growing wave spectrum was set up (see Eq. (2) in the text). The model involves a parameter indicating the growing degree of wind wave, i. e. ,the mean wave age β. When βvalue is small, the wave energy is chiefly concentrated near the peak frequency, so that the spectral peak gets high and steep; with the increase of β the spectral shape gradually gets lower and gentler; when β=Ⅰ, the wave fully grows, the growing spectrum becomes a fully grown P-M spectrum. The model also shows a spect 相似文献

ABSTRACT. Levels of alcohol consumption are a major public health issue. This study aims to gain a better understanding of how geographical patterns of religious affiliation in the United States relate to geographical patterns of alcohol consumption. We explored state‐level correlations between alcohol consumption and religious adherence. Although we found no statistically significant correlation between overall religious adherence rates and current or binge drinking rates, states with higher adherence rates were significantly more likely to have high proportions of binge drinking among current drinkers. Yet, regionally, we found a strong inverse correlation in the Southeast and a strong positive correlation in the Midwest and Northeast between adherence rates and current and binge drinking rates. These geographical differences were largely explained after stratifying by major religious denominational groupings. States with high Catholic adherence rates tended to have higher drinking rates, whereas states with high Evangelical Protestant adherence rates tended to have lower drinking rates. These findings suggest that the relationship between religion and alcohol may be denomination‐specific and challenge the lay perception that religious adherence per se is associated with less alcohol consumption and less excessive drinking among those who drink. 相似文献

Evaluation of EDI derived from the exponential evapotranspiration model for monitoring China’s surface drought 总被引:1,自引:4,他引:1

Drought has become the most severe natural disaster in many provinces of China. In this paper, evaporative drought index (EDI)
has been used to monitor China’s surface dryness conditions based on the exponential evapotranspiration (ET) model and Hargreaves
equation from JAXA-MODIS Insolation products, GEWEX, NCEP-2 and MODIS NDVI data. The exponential ET model based on the surface
net radiation, vegetation index, mean air temperature and diurnal air temperature range (DTaR) has been developed to estimate
surface ET of China and has been independently validated using ground-measured data collected from two sites (Arou and Miyun)
in China, indicating that the bias varies from −5.96 to 5.02 W/m2. The good agreement between daily estimated and ground-measured ET using ground observation data collected from all 22 sites
further supports the validity of the exponential ET model for regional ET estimation. Moreover, EDI is closely correlated
to the average soil moisture at 0–10 cm soil depth of the Yongning site with coefficient of determination of R
2 = 0.52. The spatio-temporal patterns of monthly ET and EDI from April to September of 2004 over China are explored and the
result indicates EDI is accordant with the precipitation by comparing the 15-day smoothed EDI with precipitation over six
representative sites. The EDI based on the exponential ET model by integrating energy fluxes in response to soil moisture
stress has demonstrated its validity for monitoring China’s surface drought events. 相似文献
