Attitudes Towards and Uses of the Japanese Adverbzenzen by Swedish Learners of Japanese

The word zenzen is an adverb that is used frequently in daily conversational Japanese. From the Meiji period (1868-1912) until the early Showa period (1924-1989) the word was used together with both affirmative and negative words to form expressions. In the early Showa period the grammatical rules in education changed so that the only acceptable use was together with a negative word. From the 1990’s onward, the use together with an affirmative word has made a comeback especially among younger Japanese people. However even though the usage together with an affirmative word has made a comeback and was considered normal once in history, in today’s society it is still considered as slang and thus not recommended usage in formal situations. Foreign language learners however, tend not to learn a language only by textbooks but also by imitating the language of native Japanese speakers and Japanese popular culture. This may lead to a confusion regarding what words are acceptable to use in conversations. Therefore in this study, an online survey that examines the usage and attitudes regarding the word zenzen aimed at Japanese language learners at Swedish universities was conducted. The results of the survey showed that although a majority of the learners showed a good understanding of the usage, more than half of the learners displayed a feeling of confusion regarding the usage of the word. The gender comparison regarding the usage showed no major differences. Having lived in Japan, having Japanese friends whom you speak Japanese with regularly and length of Japanese study was associated with an increased understanding of the usage. Regular consumption of Japanese popular culture, however, was not associated with an increased understanding of the usage. A literature analysis was also conducted to examine the attitudes regarding the usage of zenzen in a variety of books with topics including business language and books aimed at Japanese language teachers. The results showed that zenzen used together with a negative word was considered as the norm while zenzen used together with an affirmative word was not recommended to be used in formal situations. When recommending proper usage of the word zenzen together with an affirmative word to foreign learners of Japanese, hijou-ni and totemo was seen as better alternatives to zenzen in a formal situation.

Defining the role of common variation in the genomic and biological architecture of adult human height

Using genome-wide data from 253,288 individuals, we identified 697 variants at genome-wide significance that together explained one-fifth of the heritability for adult height. By testing different numbers of variants in independent studies, we show that the most strongly associated ∼2,000, ∼3,700 and ∼9,500 SNPs explained ∼21%, ∼24% and ∼29% of phenotypic variance. Furthermore, all common variants together captured 60% of heritability. The 697 variants clustered in 423 loci were enriched for genes, pathways and tissue types known to be involved in growth and together implicated genes and pathways not highlighted in earlier efforts, such as signaling by fibroblast growth factors, WNT/β-catenin and chondroitin sulfate-related genes. We identified several genes and pathways not previously connected with human skeletal growth, including mTOR, osteoglycin and binding of hyaluronic acid. Our results indicate a genetic architecture for human height that is characterized by a very large but finite number (thousands) of causal variants.2014

Processes and variations in language economisation

This article analyses the processes of reducing language in textchats produced by non-native speakers of English. We propose that forms are reduced because of their high frequency and because of the discourse context. A wide variety of processes are attested in the literature, and we find different forms of clippings in our data, including mixtures of different clippings, homophone respellings, phonetic respellings including informal oral forms, initialisms (but no acronyms), and mixtures of clipping together with homophone and phonetic respellings. Clippings were the most frequent process (especially back-clippings and initialisms), followed by homophone respellings. There were different ways of metalinguistically marking reduction, but capitalisation was by far the most frequent. There is much individual variation in the frequencies of the different processes, although most were within normal distribution. The fact that nonnative speakers seem to generally follow reduction patterns of native speakers suggests that reduction is a universal process.

Genome-wide association mapping in a wild avian population identifies a link between genetic and phenotypic variation in a life-history trait

Understanding the genetic basis of traits involved in adaptation is a major challenge in evolutionary biology but remains poorly understood. Here, we use genome-wide association mapping using a custom 50 k single nucleotide polymorphism (SNP) array in a natural population of collared flycatchers to examine the genetic basis of clutch size, an important life-history trait in many animal species. We found evidence for an association on chromosome 18 where one SNP significant at the genome-wide level explained 3.9% of the phenotypic variance. We also detected two suggestive quantitative trait loci (QTLs) on chromosomes 9 and 26. Fitness differences among genotypes were generally weak and not significant, although there was some indication of a sex-by-genotype interaction for lifetime reproductive success at the suggestive QTL on chromosome 26. This implies that sexual antagonism may play a role in maintaining genetic variation at this QTL. Our findings provide candidate regions for a classic avian life-history trait that will be useful for future studies examining the molecular and cellular function of, as well as evolutionary mechanisms operating at, these loci.
