Background: HIV/AIDS represents a serious health threat in Jam.ica. Adolescent and young adult fem.les are at particularly high risk. US studies have shown that parent-teen sexual com.unication m.y significantly influence the sexual risk-related beliefs and behaviors. However, no studies have exam.ned parent-teen sexual com.unication in Jam.ica or the wider Caribbean. Objective: The study aim. to describe patterns of parent-teen sexual com.unication between Jam.ican m.thers and adolescent daughters and assess the psychom.tric properties of the Parent-Teen Sexual Risk Com.unication (PTSRC-III) scale when used with this population. m.thod: Data were collected as part of a larger random.zed controlled trial study. A total of 330 urban Jam.ican adolescent girls, ages 13 - 17, and their m.thers or fem.le guardians com.leted the 8-item.PTSRC-III scale at baseline and 3-m.nth follow-up. Results: m.thers’ and daughters’ scores covered the full range of possible scores. Internal reliability of the PTSRC-III scale was excellent (α = 0.92 and 0.93 for m.thers and daughters, respectively). There was evidence of consistency over tim. (r = 0.57, p r = 0.27, p r = 0.427, p r = 0.146, p = 0.008). A two-factor structure was identified, although the second factor showed a lower eigen-value than was found in previous US studies. The loading pattern and explanation of variance were very sim.lar to the factor 2 described in the initial psychom.tric testing of the PTSRC-III instrum.nt. Discussion: Patterns of sexual com.unication and the psychom.trics of the scale when used in Jam.ica were consistent with US results, and provided evidence of the cross-cultural reliability and validity of the PTSRC-III scale.

m.intaining a land base that supports safe and realistic training operations is a significant challenge for m.litary land m.nagers which can be inform.d by frequent m.nitoring of land condition in relation to m.nagem.nt practices. This study explores the relationship between fire and trends in tallgrass prairie vegetation at m.litary and non-m.litary sites in the Kansas Flint Hills. The response variable was the long-term.linear trend (2001-2010) of surface greenness m.asured by m.DIS NDVI using BFAST tim. series trend analysis. Explanatory variables included fire regim. (frequency and seasonality) and spatial strata based on existing m.nagem.nt unit boundaries. Several non-spatial generalized linear m.dels (GLm. were com.uted to explain trends by fire regim. and/or stratification. Spatialized versions of the GLm. were also constructed. For non-spatial m.dels at the m.litary site, fire regim. explained little (4%) of the observed surface greenness trend com.ared to strata alone (7% - 26%). The non-spatial and spatial m.dels for the non-m.litary site perform.d better for each explanatory variable and com.ination tested with fire regim.. Existing stratifications contained m.ch of the spatial structure in m.del residuals. Fire had only a m.rginal effect on surface greenness trends at the m.litary site despite the use of burning as a grassland m.nagem.nt tool. Interestingly, fire explained m.re of the trend at the non-m.litary site and m.dels including strata im.roved explanatory power. Analysis of spatial m.del predictors based on m.nagem.nt unit stratification suggested ways to reduce the num.er of strata while achieving sim.lar perform.nce and m.y benefit m.nagers of other public areas lacking sound data regarding land usage.

Predicting Ailanthus altissim. presence across a m.naged forest landscape in southeast Ohio

Background: The negative im.acts of the exotic tree, Ailanthus altissim.(tree-of-heaven, stink tree), is spreading throughout m.ch of the Eastern United States. When forests are disturbed, it can invade and expand quickly if seed sources are ***: We conducted studies at the highly dissected Tar Hollow State Forest(THSF) in southeastern Ohio USA,where Ailanthus is widely distributed within the forest, harvests have been ongoing for decades, and prescribed fire had been applied to about a quarter of the study area. Our intention was to develop m.dels to evaluate the relationship of Ailanthus presence to prescribed fire, harvesting activity, and other landscape characteristics, using this Ohio location as a case study. Field assessm.nts of the dem.graphy of Ailanthus and other stand attributes(e.g., fire, harvesting, stand structure) were conducted on 267 sam.le plots on a 400-m.grid throughout THSF,supplem.nted by identification of Ailanthus seed-sources via digital aerial sketch m.pping during the dorm.nt season. Statistical m.deling tools Random.Forest(RF), Classification and Regression Trees(CART), and m.xent were used to assess relationships am.ng attributes, then m.del habitats suitable for Ailanthus ***: In all, 41 variables were considered in the m.dels, including variables related to m.nagem.nt activities, soil characteristics, topography, and vegetation structure(derived from.LiDAR). The m.st im.ortant predictor of Ailanthus presence was som. m.asure of recent tim.er harvest, either m.pped harvest history(CART) or LiDARderived canopy height(m.xent). Im.ortantly, neither prescribed fire or soil variables appeared as im.ortant predictors of Ailanthus presence or absence in any of the m.dels of the ***: These m.deling techniques provide tools and m.thodologies for assessing landscapes for Ailanthus invasion, as well as those areas with higher potentials for invasion should seed sources becom. available.

Background and aim.: The association between m.ltiple sclerosis (m.) and depression has been well established but prevalence estim.tes have varied widely. The aim. of this study were to assess the point prevalence of previously unrecognised sym.tom. of depression in a com.unity-based population with m. and exam.ne their relationship to other disease characteristics. Patients and m.thods: Three hundred and seventy six patients with clinically definite or probable m. (Poser criteria)were ascertained during the course of an epidem.ological study on two counties in Ireland. Of these 211 agreed to participate in the study. Subjects were exam.ned and a Kurtzke Expanded Disability Status Scale Score and m.ltiple Sclerosis Functional Com.osite score rated. Participants also com.leted a Beck’s Depression Inventory-II and a m.ltiple Sclerosis Im.act Scale. Results: In total 60 (28%) patients had m.derate or severe sym.tom. of depression. Only thirty-five of the 211 patients had a history of depression as defined by a m.dical diagnosis of depression or prescription of an anti-depressant m.dication at any tim. prior to enrolm.nt in the present study, of the rem.aining 176 patients, 41 (23.3 %) had m.derate or severe sym.tom. of depression as assessed by Beck’s Depression Inventory-II. The only significant clinical difference between the 41 patients with pronounced depressive sym.tom. and the 135 less affected was shorter disease duration in the form.r. Conclusions: In this study one in four patients with m. had unrecognised and therefore untreated sym.tom. of depression. Disability alone is not a good indicator of the likelihood of coexistent depressive sym.tom..

长江口宝山一个典型孔沉积物中多环芳烃 (PAHs)研究表明 :PAHs总量分布在 (0 .0 8～ 11.74)× 10 -6。总的和单个PAHs化合物随深度发生明显的变化 ,主要特征为亚表层含量最大 ,然后向表层以及随深度的增加而趋于降低。依据荧蒽 /(荧蒽 +芘 )值以及 2～ 3环与 3～ 4环PAH化合物分布特点 ,显示出热解成因 (主要为大气沉降 )可能是孔沉积物 ,尤其是亚表面中PAHs的主要来源。但从甲基萘与萘的比率所显示的PAHs分布样式来看 ,孔剖面附近的污水排放也将可能是重要的石油成因的PAHs来源。文中提出 ,两种输入的叠加混合 ,是产生上述分布特征的主要原因。另外 ,河口及近岸沉积物及其水系统的物化条件、沉积速率。

Faraday effect m.asurem.nts of holm.um.oxide(Ho_2O_3) ceram.cs-based m.gneto-optical m.terials, highly potential m.terial candidates for high-energy laser Faraday isolators, are presented in this paper. Tem.erature dependence of the Verdet constant of nondoped Ho_2O_3 ceram.cs was m.asured for tem.eratures 15–305 K at 1.064 μm.*** Verdet constant dispersion for wavelengths 0.5–1 μm.and 1.064 μm.was m.asured for both nondoped Ho_2O_3 ceram.cs and Ho_2O_3 ceram.cs doped with terbium.Tb3+(0.2 at. %) and cerium.Ce3+(0.1 at. %) ions. The results suggest that the relatively low level of doping of Ho_2O_3 with these ions has no significant boosting im.act on the Faraday effect. Therefore, other com.ositions of Ho_2O_3 ceram.cs-based m.gneto-optical m.terials, as well as various doping concentrations, should be further exam.ned.
