By using two different measures （translation production and selection）, this study found： （1） Vocabulary can be acquired incidentally in reading passages; （2） There are no significant interactive effects of topic familiarity and second language proficiency on vocabulary acquisition, but the two independent variables of topic familiarity and second language proficiency exerted their positively significant effect on incidental vocabulary acquisition, and （3） As for the two vocabulary measures, learners can acquire more words in translation selection than in translation production.展开更多

However, it does not mean that learners must abandon their own culture in order to avoid the potential cultural collision. What they need to do is to accumulate the knowledge pertaining to the target culture so as to develop cross-cultural awareness. This paper will draw on previous research in this arena as well as the author＇s personal knowledge to further explore the relationship between socioculture and second language acquisition from the perspectives of culture and language, cultural confrontation, and culture familiarization.展开更多

Methods Three families of suspected FAP in China mainland and Macao were investigated on aspects of clinical manifestations, histological features, and gene analysis. Results All the 3 families had the clinical features of sensory and motor polyneuropathies, and notable vegetative nerve involvements. Affected cases of one family had ultrasound proved cardiomyopathy. Histological studies showed amyloid deposition in all the biopsy tissues of the affected cases of the 3 families, and anti-transthyretin antisera staining was positive in 3 cases of one family. Gene analysis confirmed that mutation types were amyloidogenic transthyretin (ATTR) Val30Met, Phe33Val, and Gly67Glu in the 3 families respectively. The ATTR Gly67Glu family had a shorter survival time due to the heart involvement compared with the other 2 families. Conclusion FAP is an autosomal dominant inherited disease, with its clinical manifestations related to the type of genetic mutation.展开更多

As a consequence, a handful of avian species have been discovered to use olfaction in different contexts. Nevertheless, we still have a very limited knowledge about the use of odor cues in avian social life, particularly, in the case of songbirds. Here, we investigate if female house sparrows Passer domesticus show any preference for the odor of kin and nonkin conspecifics and we also test a possible role of familiarity based on male see nt in female choice. We performed the experiment with captive birds twice, duri ng the non breeding and breedi ng seas ons. Our results show that female house sparrows strongly avoided the odor of unrelated familiar (UF) males, both in the breeding and nonbreeding seasons. Our results suggest recognition for olfactory stimuli related to familiarity and kin ship. We suggest that avoidance for UF males is associated with previous experie nee in this species. Also, we provided further evidenee to the use of olfaction in passerine species by using a new experimental setup.展开更多

Methods:Participants saw a series of pictures with either blue or red background,and were then given a pretest for item and source memories. Then males and females respectively were randomly assigned either to a wake or a sleep condition. In the wake condition,participants remained awake until the posttest;in the sleep condition,participants slept for 1 h until awakened and asked to remain awake until the posttest. Results:Daytime sleep contributed to retention of source memory rather than item memory in females,whereas males undergoing daytime sleep had a trend towards increased familiarity. For females,however,neither recollection nor familiarity appeared to be influenced by daytime sleep. Conclusion:The mechanism underlying gender difference may be linked with different memory traces resulting from different encoding strategies,as well as with different electrophysiological changes during daytime sleep.展开更多

Methods: Gastric cancer family histories within second degree relatives and clinicopathological features were obtained for 497 patients. Results:Of the 497 probands,235 probands were incorporated into familial gastric cancer (FGC) group (there were at least two GC members in the family); 262 probands were included in the non-FGC group (relatives only affected with non-GCs). Of 614 tumors in relatives,GC was the most frequent,followed by lung cancer,esophageal cancer,hepatocellular cancer,colorectal cancer,urogenital cancer,breast cancer,and pancreatic cancer. Most affected members aggregated within first-degree relatives. The ratio of males to females in affected first-degree relatives was usually higher in male probands. Paternal history of GC was a strong risk for GC in males,while risk of GC by maternal history of GCs was increased in females. Difference in tumor histological types between the two groups was derived from an excess of diffuse GC in non-FGC male probands. The lower site was the most frequent tumor location in all subgroups. Conclusion:Distribution of associated non-GCs in a family history of GC may vary with geographic areas. GC may have different genetic and/or environmental etiology in different families,and a certain subtype may be inherited in a male-influenced fashion.展开更多

However, the cortical mechanisms underlying the episodic recall of emotional scenes are still poorly understood. Our main aim was to compare the magnitude of the Event-Related brain Potentials (ERP) old-new effect related to emotionally unpleasant, pleasant and neutral photographic images. As expected, correct recognition of all types of images elicited three topographically distinct ERP components sensitive to the classical old-new recognition effect. The results revealed that the behavioral performances were mainly sensitive to arousal, while the ERP old/new effect over posterior regions (300 - 1000 ms) was exclusively affected by unpleasantness. A later component (1000 - 1400 ms) showed an inverted old/ new effect at parietal sites, which was also sensitive to unpleasantness. These results imply that ERP reflecting episodic conscious recollection and post-retrieval monitoring are clearly affected both by valence and arousal.展开更多

文摘Based on the interactive theory of reading, this study mainly explored the etlects ot topic familiarity and second language proficiency on IVA （Incidental Vocabulary Acquisition） of second language through reading. By using two different measures （translation production and selection）, this study found： （1） Vocabulary can be acquired incidentally in reading passages; （2） There are no significant interactive effects of topic familiarity and second language proficiency on vocabulary acquisition, but the two independent variables of topic familiarity and second language proficiency exerted their positively significant effect on incidental vocabulary acquisition, and （3） As for the two vocabulary measures, learners can acquire more words in translation selection than in translation production.
文摘Since no language can exist in a cultural vacuum, and since no two cultures are exactly identical, second or foreign language learners will inevitably encounter cultural confrontations on their learning route. However, it does not mean that learners must abandon their own culture in order to avoid the potential cultural collision. What they need to do is to accumulate the knowledge pertaining to the target culture so as to develop cross-cultural awareness. This paper will draw on previous research in this arena as well as the author＇s personal knowledge to further explore the relationship between socioculture and second language acquisition from the perspectives of culture and language, cultural confrontation, and culture familiarization.

文摘Kin selection theory predicts that individuals should generally behave less aggressively or more amicably towards relatives than nonkin.However,how individuals treat conspecifics depends on genetic relatedness but also on the ecological context,which influences the benefits and costs of their interactions.In this study,we used microsatellite DNA markers and behavioral tests to examine the influence of kinship and proximity on the social behavior of Mongolian gerbils Meriones unguiculatus living in different social groups,and whether these effects varied with sex and season.We recorded the duration of 4 behavioral categories(investigative,neutral,amicable,and agonistic)during a 10-min pairwise test.We found that genetic relatedness had significant effects on the duration of investigative,neutral,and amicable behavior,but not on agonistic behavior.We also found significant interaction effects of relatedness and distance between burrow systems(i.e.,spatial distance)on investigative,neutral,and amicable behavior,which suggests that the effects of kinship on social behavior were restricted by spatial proximity.The interaction effect between sex and relatedness on amicable behavior showed that male gerbils became more intimate with individuals of the same sex that had higher pairwise relatedness than females.Furthermore,both male and female gerbils enhanced their aggression during the food-hoarding season,but the intensity of these changes was significantly higher in females.Overall,our results suggest that the effects of kinship and spatial proximity on social behavior exhibit sexual or seasonal patterns,thereby implying ecological context-dependent responses to out-group individuals in Mongolian gerbils.

文摘Objective:To investigate gender difference in the effects of daytime sleep on item and source memories,which are dissociable elements of declarative memory,and the effects of sleep on recollection and familiarity,which are two processes underlying recognition. Methods:Participants saw a series of pictures with either blue or red background,and were then given a pretest for item and source memories. Then males and females respectively were randomly assigned either to a wake or a sleep condition. In the wake condition,participants remained awake until the posttest;in the sleep condition,participants slept for 1 h until awakened and asked to remain awake until the posttest. Results:Daytime sleep contributed to retention of source memory rather than item memory in females,whereas males undergoing daytime sleep had a trend towards increased familiarity. For females,however,neither recollection nor familiarity appeared to be influenced by daytime sleep. Conclusion:The mechanism underlying gender difference may be linked with different memory traces resulting from different encoding strategies,as well as with different electrophysiological changes during daytime sleep.
