| 1 | 古里雅冰帽中化学成分的空间变化显示文摘表面样和钻取样的离子浓度都随采样点距最高点(6800m)之间距离的增大而增大,钻取样的这一变化比表面样更明显。这种变化可归因于雪中的杂质主要来自陆源物质。在距最高点5km处离子浓度及δ^(18)O的变化反映了雪的融化作用。 | 李月芳 姚檀栋 皇翠兰 L.Thompson | 1993 | 冰川冻土1993,15,3: | 24 |
| 2 | 美国2007年农业法案对发展中国家的启示(上)显示文摘近年来,经合组织(OECD)国家对农业实行大量补贴,而发展中国家的农民却面临困难,这两者之间的联系已经成为人们关注的焦点。毫无疑问,经合组织国家的农业计划对世界市场的结构产生了巨大的影响,对贸易量、贸易流向及国际农产品价格都产生了影响。世界银行的一份评估认为,它对不同产品的国际价格的影响在10到50%之间不等(见表1)。与此同样重要的一个启示是:许多经合组织国家的农业政策旨在保护他们的农业部门不受外国竞争,甚至在鼓励其他国家开放农产品市场时也是如此。 | 迪姆·卓斯林(Tim Josling) 丹尼尔A.塞莫尔(Daniel A.Sumner) 罗伯特L.汤普森(Robert L.Thompson) 玛丽·查普里斯(Mary Chambliss) 卡拉·兰尼(Kara Laney) 王晓宇(翻译) 刘健男(校译) | 2008 | WTO经济导刊2008,,4: | 3 |
| 3 | Physical activity during pregnancy and the role of theory in promoting positive behavior change:A systematic review显示文摘Background: Physical activity(PA) during pregnancy provides physical and psychological benefits for mother and child. U.S. guidelines recommend ≥30 min of moderate exercise for healthy pregnant women most days of the week; however, most women do not meet these recommendations. Theory assists in identifying salient determinants of health behavior to guide health promotion interventions; however, the application of theory to examine PA among pregnant women has not been examined cohesively among multiple levels of influence(e.g.,intrapersonal, interpersonal, neighborhood/environmental, and organizational/political). Subsequently, this systematic review aims to identify and evaluate the use of health behavior theory in studies that examine PA during pregnancy.Methods: Articles published before July 2014 were obtained from Pub Med and Web of Science. Inclusion criteria applied were:(1) empiricallybased;(2) peer-reviewed;(3) measured factors related to PA;(4) comprised a pregnant sample; and(5) applied theory. Fourteen studies were included. Each study's application of theory and theoretical constructs were evaluated.Results: Various theories were utilized to explain and predict PA during pregnancy; yet, the majority of these studies only focused on intrapersonal level determinants. Five theoretical frameworks were applied across the studies—all but one at the intrapersonal level. Few determinants identified were from the interpersonal, neighborhood/environmental, or organizational/political levels.Conclusion: This systematic review synthesized the literature on theoretical constructs related to PA during pregnancy. Interpersonal, community,and societal levels remain understudied. Future research should employ theory-driven multi-level determinants of PA to reflect the interacting factors influencing PA during this critical period in the life course. | Erika L.Thompson Cheryl A.Vamos Ellen M.Daley | 2017 | Journal of Sport and Health Science2017,6,2: | 1 |

| 7 | A semi-analytical approach for calculating the equilibrium structure and radial breathing mode frequency of single-walled carbon nanotubes显示文摘A semi-analytical model for determining the equilibrium configuration and the radial breathing mode(RBM)frequency of single-wall carbon nanotubes(CNTs) is presented. By taking advantage of the symmetry characteristics,a CNT structure is represented by five independent variables. A line search optimization procedure is employed to determine the equilibrium values of these variables by minimizing the potential energy. With the equilibrium configuration obtained, the semi-analytical model enables an efficient calculation of the RBM frequency of the CNTs. The radius and radial breathing mode frequency results obtained from the semi-analytical approach are compared with those from molecular dynamics(MD) and ab initio calculations.The results demonstrate that the semi-analytical approach offers an efficient and accurate way to determine the equilibrium structure and radial breathing mode frequency of CNTs. | J.Gong L.Thompson G.Li | 2016 | Acta Mechanica Sinica2016,32,6: | 1 |
| 8 | The association of inherited variation in the CLOCK gene with breast cancer tumor grade显示文摘Background:Sufficient sleep and maintenance of circadian rhythm are important to health.We have shown that short duration of sleep before diagnosis is associated with higher-grade tumors among breast cancer patients.Earlier studies suggest that genetic variation in the CLOCK gene is associated with risk of cancers,including breast cancer.Studies of the association of genetic variation,including in CLOCK,and tumor grade,a standard marker of tumor aggressiveness,are lacking.Methods:We investigated the relationship between single nucleotide polymorphisms(SNPs)in the CLOCK gene and tumor grade and estrogen receptor,progesterone receptor,and human epi-dermal growth factor receptor 2 status in 293 breast cancer patients.Nine SNPs were determined by standard TaqMan assays.Tumor grade,receptor status,and other clinical variables were abstracted from medical records.Results:Two SNPs were excluded because of poor genotyping performance.None of the remaining seven variants had a statistically significant association with breast cancer tumor grade or with receptor status.Conclusion:As with all novel studies,further work is needed to examine the association of CLOCK and other genes in the circadian rhythm pathway with breast cancer tumor grade in other populations. | Neha Gupta Li Li Cheryl L.Thompson | 2017 | Family Medicine and Community Health2017,5,2: | 0 |
| 9 | Short sleep duration as a contributor to racial disparities in breast cancer tumor grade显示文摘Although African Americans(AAs)are less likely to get breast cancer than European Americans(EAs),they get more aggressive forms.We previously showed that short sleep is associated with higher tumor grade.It is well documented that AAs get less sleep,on average,than EAs.We studied the contribution of short sleep to racial disparities in breast cancer aggressiveness among 809 invasive breast cancer patients who responded to a survey on their lifestyle.Multivariable regressions and mediation analyses were performed to assess the effect of sleep duration on the association of race with tumor grade.AAs reported shorter average sleep(mean[standard devia-tion]6.57[1.47]h)than EAs(mean[standard deviation]7.11[1.16]h;P<0.0001)and were almost twice as likely to report less than 6 h of sleep per night(48.0%vs.25.3%,P<0.0001).AA patients were more likely to have high-grade tumors(52.6%vs.28.7%in EAs,P=0.0002).In multivariate analysis,race was associated with tumor grade(P<0.0001).On adjustment for sleep duration,the effect of race was reduced by 7.1%,but remained statistically significant(P=0.0006).However,the Sobel test did not indicate statistical significance(z=1.69,P=0.091).In other models accounting for these and additional confounders,we found similar results.Because of the conservative nature of the mediation analysis and smaller sample size,replication of our results in larger studies with more AA patients is warranted. | Kevin Allan Nathan A.Berger Li Li Cheryl L.Thompson | 2017 | Family Medicine and Community Health2017,5,2: | 0 |

| 11 | Nocturnal foragers exploit tree exudates from holes gouged by diurnal common marmoset monkeys(Callithrix jacchus)显示文摘INTRODUCTION Plant exudates are a common,yet often overlooked food source eaten by 94 mammalian species spread across 6 orders(Nash&Burrows 2010;Cabana et al.2018).However,exudates(including gums,resins,and latex,defined following Cabana et al.2018)contain large amounts of non-digestible carbohydrates and plant secondary metabolites,posing challenges for mammals exploiting this resource(Power 2010).Due to the difficulty of gaining nutrition from exudates,they are not considered a high-quality food source,despite the number of species that consume them(Power 2010;Cabana et al.2018). | Cynthia L.THOMPSON Lauren M.GAPP Leonardo C.O.MELO Christopher J.VINYARD Maria A.B.DE OLIVEIRA | 2020 | Integrative Zoology2020,15,6: | 0 |
