Women's beliefs about the appetite and weight control properties of cigarette smoking, dietary restraint and disinhibition, and smoking status were examined. As hypothesized, dietary restraint and disinhibition predicted appetite and weight control expectancies and smoking rate, such that women higher in dietary restraint and disinhibition reported stronger beliefs in the appetite and weight control properties of cigarettes and were more likely to be smoking than those lower in dietary restraint and disinhibition. Consistent with previous research, smoking expectancies for appetite and weight control predicted smoking status and smoking rate. Smoking expectancies for appetite and weight control were found to mediate the relationship between dietary restraint and smoking, and between disinhibition and smoking. This relationship between smoking and dietary constructs should be considered in smoking cessation and dietary interventions with young women.

To support the 2012 Great Lakes Water Quality Agreement on reducing Lake Erie's phosphorus inputs, we integrated US and Canadian data to update and extend total phosphorus (TP) loads into and out of the St. Clair-Detroit River System for 1998–2016. The most significant changes were decreased loads from Lake Huron caused by mussel-induced oligotrophication of the lake, and decreased loads from upgraded Great Lakes Water Authority sewage treatment facilities in Detroit. By comparing Lake St. Clair inputs and outputs, we demonstrated that on average the lake retains 20% of its TP inputs. We also identified for the first time that loads from resuspended Lake Huron sediment were likely not always detected in US and Canadian monitoring programs due to mismatches in sampling and resuspension event frequencies, substantially underestimating the load. This additional load increased over time due to climate-induced decreases in Lake Huron ice cover and increases in winter storm frequencies. Given this more complete load inventory, we estimated that to reach a 40% reduction in the Detroit River TP load to Lake Erie, accounting for the missed load, point and non-point sources other than that coming from Lake Huron and the atmosphere would have to be reduced by at least 50%. We also discuss the implications of discontinuous monitoring efforts. 相似文献

This work reports a systematic comparative study of the technological properties of natural lattices and rubbers extracted from Hancornia speciosa Gomes and Hevea brasiliensis [(Willd. ex Adr. de Juss.) Muell.‐Arg.] (clone RRIM 600) trees from 11 collections in Brazil throughout 2004. Natural rubber latex particle sizes and distributions were quite similar with an average diameter around 1 μm. Molecular weight, Wallace plasticity, and Mooney viscosity values were approximately the same for both rubbers. Fourier transform infrared spectroscopy peaks characteristic of natural rubber were observed for both Hancornia and Hevea. The measured differences in technological properties included lower values for Hancornia dry rubber content, % ash, % nitrogen, and plasticity retention index but higher value for acetone extract. Interestingly, nitrogen and protein content were much lower in Hancornia, suggesting that it may have important applications in nonallergic rubber uses. This represents the first report of lacticifer‐produced low‐protein natural rubber. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009 相似文献

This article introduces tourism as a neglected topic of study for psychologists and discusses how ventures into this area provide opportunities for pioneering research and innovative applications. A coherent body of theory, drawn from experimental, social, and health psychology and synthesized by cross-cultural psychologists for the study of acculturation, is presented as one foundation for this area of inquiry. This includes stress and coping, culture learning, and social identification theories. The conceptual frameworks are applied to the interpretation of selected studies of tourism and are recommended for designing prospective investigations and guiding future research.

The current research synthesis integrates the findings of 111 independent samples from 54 economically developing countries that examined the relation between economic status and subjective well-being (SWB). The average economic status-SWB effect size was strongest among low-income developing economies (r = .28) and for samples that were least educated (r = .36). The relation was weakest among high-income developing economies (r = .10) and for highly educated samples (r = .13). Controlling for numerous covariates, the partial r effect size remained significant for the least-educated samples (pr = .18). Moderator analyses showed the economic status-SWB relation to be strongest when (a) economic status was defined as wealth (a stock variable), instead of as income (a flow variable), and (b) SWB was measured as life satisfaction (a cognitive assessment), instead of as happiness (an emotional assessment). Findings were replicated with a meta-analysis of the World Values Survey data. Discussion centers on the plausibility of need theory, alternative explanations of results, interpretation of moderators, and directions for future research.

The heartwood of plantation-grown Cupressus lusitanica, C. macrocarpa, Leyland and Ovens cypress (×Cuprocyparis leylandii and ×C. ovensii) from trials in New Zealand, was evaluated using breast height increment cores and in vitro decay tests with fungal cultures to determine the variation in the heartwood content and natural durability, and its prediction using near-infrared (NIR) spectroscopy. The increment core measurements showed the length of the cores was strongly influenced by the stocking and site, but the heartwood content and weight loss with decay testing were strongly influenced by species and genotype. The heartwood content was consistently high for C. macrocarpa, but varied widely for C. lusitanica, and the Leyland and Ovens cypress clones. The weight loss was similar for the species and cypress clones, with the heartwood classified as very durable and durable, but there were differences in the distributions of less durable heartwood. The NIR calibration models of mass loss with fungal decay testing had ratios of prediction to deviation (RPD) of 1.0–1.3, which suggests the models could be used to segregate the heartwood for high and low values of natural durability. 相似文献

Over the past decade, several large epidemiologic investigations of meat intake and prostate cancer have been published. Therefore,
a meta-analysis of prospective studies was conducted to estimate potential associations between red or processed meat intake
and prostate cancer. Fifteen studies of red meat and 11 studies of processed meat were included in the analyses. High vs.
low intake and dose-response analyses were conducted using random effects models to generate summary relative risk estimates
(SRRE). No association between high vs. low red meat consumption (SRRE = 1.00, 95% CI: 0.96-1.05) or each 100 g increment
of red meat (SRRE = 1.00, 95% CI: 0.95-1.05) and total prostate cancer was observed. Similarly, no association with red meat
was observed for advanced prostate cancer (SRRE = 1.01, 95% CI: 0.94-1.09). A weakly elevated summary association between
processed meat and total prostate cancer was found (SRRE = 1.05, 95% CI: 0.99-1.12), although heterogeneity was present, the
association was attenuated in a sub-group analysis of studies that adjusted for multiple potential confounding factors, and
publication bias likely affected the summary effect. In conclusion, the results of this meta-analysis are not supportive of
an independent positive association between red or processed meat intake and prostate cancer. 相似文献
