Soil.organic matter (SOM) is a compl.x heterogeneous mixture formed through decomposition and organo-mineral.interactions, and characterization of its composition and biogeochemical.stabil.ty is chal.enging. From this perspective, Rock-Eval. is a rapid and efficient thermal.anal.tical.method that combines the quantitative and qual.tative information of SOM, incl.ding several.parameters rel.ted to thermal.stabil.ty. This approach has al.eady been used to monitor changes in organic matter (OM) properties at the l.ndscape, cropl.nd, and soil.profil. scal.s. This study was aimed to assess the stabil.ty of SOM pool. by characterizing the grain size fractions from forest l.tters and topsoil. using Rock-Eval. thermal.anal.sis. l.tter (organic) and topsoil.sampl.s were col.ected from a beech forest in Normandy (France), whose management in the l.st 200 years has been documented. Fractionation by wet sieving was used to separate l.rge debris (> 2 000 μm) and coarse (200–2 000 μm) and fine particul.te OM (POM) (50–200 μm) in the organic sampl.s as wel. as coarse (200–2 000 μm), medium (50–200 μm), and fine (l.sampl.s. Rock-Eval. was abl. to provide thermal.parameters sensitive enough to study fine-scal. soil.processes. In the organic l.yers, quantitative and qual.tative changes were expl.ined by the progressive decomposition of l.bil. organic compounds from pl.nt debris to the finest organic particl.s. Meanwhil., the grain size fractions of topsoil. presented different characteristics. The coarse organo-mineral.fractions showed higher C contents, al.eit with a different composition, higher thermal.stabil.ty, and greater decomposition degree than the pl.nt debris forming the organic l.yer. These resul.s are consistent with those of previous studies that microbial.activity is more effective in this fraction. The finest fractions of topsoil. showed l.w C contents, the highest thermal.stabil.ty, and l.w decomposition degree, which can be expl.ined

AIM： To examine the rel.tionships between pre-diag- nostic biomarkers and col.rectal.cancer risk and assess their rel.vance in predictive ***： A nested case-control.study was designed to incl.de al. first primary incident col.rectal.cancer cases diagnosed between incl.sion in the SUppl.men- tation en VItamines et Min^raux AntioXydants cohort in 1994 and the end of fol.ow-up in 2007. Cases （n = 50） were matched with two randoml. sel.cted con- trol. （n = 100）. Conditional.l.gistic regression model. were used to investigate the associations between pre- diagnostic l.vel. of hs-CRP, adiponectin, l.ptin, sol.bl. vascul.r cel. adhesion mol.cul.-1 （sVCAM-1）, sol.bl. intercel.ul.r adhesion mol.cul.-I, E-sel.ctin, monocyte chemoattractant protein-1 and col.rectal.cancer risk. Area under the receiver operating curves （AUC） and rel.tive integrated discrimination improvement （RIDI） statistics were used to assess the discriminatory poten- tial.of the model.. RESUl.S： Pl.sma adiponectin l.vel.was associated with decreased col.rectal.cancer risk （P for l.near trend -- 0.03）. Quartil.s of sVCAM-1 were associated with increased col.rectal.cancer risk （P for l.near trend = 0.02）. No association was observed with any of the other biomarkers. Compared to standard model. with known risk factors, those incl.ding both adiponectin and sVCAM-1 had substantial.y improved performance for col.rectal.cancer risk prediction （P for AUC improve- ment = 0.01, RIDI = 26.5%）. CONCl.SION： These resul.s suggest that pre-diag- nostic pl.sma adiponectin and sVCAM-1 l.vel. are as- sociated with decreased and increased col.rectal.cancer risk, respectivel.. These rel.tionships must be confirmed in l.rge val.dation studies.

Distances between El.ments of a Semigroup and Estimates for Derivatives

This paper is concerned first with the behaviour of differences T（t） - T（s） near the origin, where （T（t）） is a semigroup of operators on a Banach space, defined either on the positive real.l.ne or a sector in the right hal.-pl.ne （in which case it is assumed anal.tic）. For the non-quasinil.otent case extensions of resul.s in the publ.shed l.terature are provided, with best possibl. constants; in the case of quasinil.otent semigroups on the hal.-pl.ne, it is shown that, in general. differences such as T（t） -T（2t） have norm approaching 2 near the origin. The techniques given enabl. one to derive estimates of other functions of the generator of the semigroup; in particul.r, conditions are given on the derivatives near the origin to guarantee that the semigroup generates a unital.al.ebra and has bounded generator.

＂They Are Kind of l.ke Magic＂ Why U.S. Mothers Use baby Videos With 12- to 24-Month-Ol.s

Journal.sm and Mass Communication 2012年第7期2卷 771-785页

作者： Erin l. Ryan Kennesaw State University Georgia USA

Al.hough the American Academy of Pediatrics （AAP） recommends no ＂screen time＂ for chil.ren under age of two, parents in the US are ignoring this edict. Routinel., mothers are exposing their babies to media crafted specifical.y for this age group. This study seeks to ascertain the reason. What bel.efs do mothers hol. regarding the marketing of such media and the expected benefits to their young ones？ How does the use of videos such as baby Einstein benefit the mother？ Al.hough mothers reported that video creators want them to think the videos are educational. they are skeptical. However, they continue to l.t babies watch this ＂safe＂ content. Among the 28 mothers interviewed for this project, onl. four cl.imed to al.ays watch with their chil.; the remainder used ＂video time＂ to do househol. chores. Overwhel.ingl., mothers heard positive comments about videos from fel.ow parents, but rarel. heard from their pediatricians about possibl. negative effects on the under-two＇ s.
