Model test of the influence of cyclic water level fluctuations on a landslide

Many landslides in reservoir areas continuously deform under cyclic water level fluctuations due to reservoir operations. In this paper,a landslide model, developed for a typical colluvial landslide in the Three Gorges Reservoir area, is used to study the effect of cyclic water level fluctuations on the landslide. Five cyclic water level fluctuations were implemented in the test, and the fluctuation rate in the last two fluctuations doubled over the first three fluctuations. The pore water pressure and lateral landslide profiles were obtained during the test. A measurement of the landslide soil loss was proposed to quantitatively evaluate the influence of water level fluctuations. The test results show that the first water level rising is most negative to the landslide among the five cycles. The fourth drawdown with a higher drawdown rate caused further large landslide deformation. An increase of the water level drawdown rate is much more unfavorable to the landslide than an increase of the water level rising rate. In addition, the landslide was found to have an adaptive ability to resist subsequent water level fluctuations after undergoing large deformation during a water level fluctuation. The landslide deformation and observations in the field were found to support the test results well.

Reading Developmental Trends in Early Years： The Influence of Word Identification Skills and Target Langauge Oral Ability to Comprehension

Language, reading, and reading-related tasks were administered to 148 children from lower primary （Standard 1, 2, and 3） in Kenyan schools. The aim was to investigate the literacy developmental trends across the years and establish which of the two variables, word identification skills or target language oral proficiency influenced reading comprehension performance. The results indicated that word identification skills independently influenced reading comprehension performance in both standard 2 and standard 3 classes, but target language oral skills did not. Further, the analysis of invented spelling task performance revealed evidence of transfer of alphabetic coding skills of first language to English orthography. The spelling errors reflected letter-sound patterns not found in English orthography. Analysis of the miscues in the spelling task revealed that children rely on first language phonological processes to spell target language unfamiliar words as long the languages have a common alphabetic system.

Effects of hydroperiod duration on developmental plasticity in tiger frog （Hoplobatrachus chinensis） tadpoles

While developmental plasticity can facilitate evolutionary diversification of organisms, the effects of water levels as an environmental pressure on tiger frogs remains unclear. This study clarifies the relationship by studying the responses of tiger frog （Hoplobatrachus chinensis） tadpoles to simulated hydroperiods （i.e., constant low water levels, constant high water levels, increasing water levels, decreasing water levels, rapid changes in water levels and gradual fluctuations in water levels） in a laboratory setting. ANOVA analysis showed that none of the water level treatments had any significant effect on the total length, body mass, or developmental stages of H. chinensis tadpoles half way through development （11 days old）. Tadpoles raised in rapidly fluctuating water levels had protracted metamorphosis, whereas tadpoles raised under low and gradually fluctuating water levels had shortened metamorphosis. None of the water level treatments had a significant effect on the snout-vent length （SVL） or body mass of H. chinensis tadpoles at Gosner stage 42, or on the body mass of tadpoles at Gosner stage 45. However, the＇ tadpoles raised in high levels and rapidly fluctuating water levels, significantly larger SVL at Gosner stage 45, while ones under gradually fluctuating water levels had smaller SVL than the other groups. Time to metamorphosis was positively correlated with body size （SVL） at metamorphosis in H. chinensis tadpoles. H. chinensis tadpoles under constant low water level had the highest mortality rate among all the treatments （G-test）. Moreover, ANOVA and ACNOVA （with body length as the covariate） indicated that water levels had no significant effect on either the morphology （i.e. head length, head width, forelimb length, hindlimb length and body width） or the jumping ability of juvenile H. chinensis. These results suggest that the observed accelerated metamorphosis and high mortality of H. chinensis tadpoles under decreasing water level treatment was driven by density-induced physical interaetions among increasing conspeeifics.

Predictors of emotional awareness during childhood

Emotional awareness, the ability to identify and describe one’s own emotions, and those of other people, has been widely studied in adult samples, while only few studies have been conducted during childhood. Aim of the present study was to investigate the predictability of the main variables usually associated with the study of emotional awareness. The LEAS-C was administered to a group of 781 children aged 8 to 13 years old. The results showed that both gender and verbal skills are important predictors of children’s emotional awareness. Moreover, cognitive ability and emotion recognition also predicted LEAS-C scores. Finally, age emerged as a significant predictor of the complexity of children’s emotional awareness. The assessment of children’s emotional awareness may be significant for different health-related purposes, e.g. prevention and psychological support.

桑树绿枝扦插繁殖过程中ABI4和PIN1基因的表达变化及与生根性能的相关性

脱落酸非敏感型转录因子ABI4、生长素运输载体蛋白PIN1分别通过调控脱落酸和生长素的运输而影响植物不定根的发育与生长。以经生根粉诱导处理和未经诱导处理的桑树绿枝插穗为材料,用实时荧光定量PCR、Western blot技术检测插穗生根发育过程中基部皮层ABI4和PIN1基因的转录与蛋白质表达水平变化。当插穗出现不定根时,ABI4的转录与表达水平急剧下调,PIN1的转录水平急剧上调,而后在新生根伸长期二者均有所回复;生根剂诱导处理插穗后加大了其基部皮层ABI4的转录与表达下调幅度和PIN1的转录上调幅度,且PIN1在新生根伸长期持续高表达。ABI4的转录水平与不同桑品种生根率之间均呈显著的负相关关系(γ=-0.915),与生根数量没有相关性;而PIN1的转录水平与生根率和生根数量均呈显著的正相关关系(γ=0.880,γ=0.982)。农桑14号和强桑1号等是绿枝生根率高的桑品种,其插穗不定根出现时基部皮层ABI4的转录、表达下调幅度和PIN1的转录上调幅度大于大10等生根率低的桑品种,提示易生根品种的插穗在不定根出现时期ABI4的低水平和PIN1的高表达会更利于插穗根原基的形成、分化及新生根的生长。
