Multiple Correspondence and Typological Convergence in Contact-Induced Grammaticalization: Evidence from Cantonese-English Bilingual Development
No full textThis paper examines the emergence of perfective aspect in Cantonese-English bilingual children from the perspective of contact-induced grammaticalization, focusing on the novel use of already. Although the adverbial already seems to serve a function similar to that of the Cantonese perfective marker zo2 in the bilingual children, other model constructions suggest that the function of already may combine those of several Cantonese particles such as the sentence-final particle laa3. The results suggest that in contact-induced grammaticalization, it is possible to develop a new category in the replica language based on multiple different but related categories in the model language. Adopting an evolutionary approach to language transmission (Mufwene, 2001), we discuss why grammaticalization in the Cantonese-English bilingual children does not seem to involve coevolution of form and meaning, why the grammaticalization phenomena in the bilingual children are only transient, and how the study of bilingual acquisition can contribute to contact linguistics
Bilingual children as "laboratories" for studying contact outcomes: Development of perfective aspect
No full textThis paper examines the close parallels between the contact phenomena in Cantonese-English bilingual children and Southeast Asian creoles, especially in the domain of perfective aspect marking. 'Already' is a cross-linguistically common lexical source of perfective aspect markers given its conceptual link with the sense of perfectivity. In contact scenarios involving a European lexifier and Southeast Asian substrates, the development of 'already' into a perfective marker is further triggered by the incompatibility between the verbal morphology of the former and the isolating typology of the latter. Adopting an ecological approach to language transmission and creole genesis we discuss how the transient grammaticalization phenomena in the bilingual children can be compared to decreolization, and how the study of bilingual acquisition can contribute to contact linguistics. Despite the prevalence of unpredictable factors in contact scenarios, we argue that bilingual children can still serve as powerful "laboratories" for studying contact outcomes at the communal level

An investigation into Chinese cybercrime and the underground economy in comparison with the West
No full textWith 420 million Internet users, China has become the world’s largest Internet population. Yet, the Internet penetration rate in China is only 31.6%, which means that the Chinese Internet population has the potential to triple in size in the foreseeable future. With cybercrimes transcending national boundaries, the security of the Internet in China is becoming increasingly significant to the global Internet. As in the West, organised cybercrimes are flourishing in China. With a rapidly expanding Internet population, China is fast becoming a giant hub of cybercrime activities. Therefore, it is in the interest of Western cyber-security experts to increase their attention to China’s cyber-security
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The impact of the regimen of screening on lung cancer cure: A comparison of I-ELCAP and NLST
No full textThe aim of this study was to assess the impact of the regimen of screening on the frequency of early diagnosis and resection in two computed tomography screening programs. The stage and size distribution of all screendiagnosed lung cancers was compared. A total of 775 patients in the International Early Lung Cancer Action Program (I-ELCAP) and 664 patients in the National Lung Screening Trial (NLST) were screen-diagnosed; that is, resulting from a positive result requiring further diagnostic workup. The frequency of stage I diagnoses, resections, tumor size, and lung cancer-specific survival were determined. Cox regression was used to identify the key determinants of lung cancer cure. The frequency of clinical stage I lung cancer in I-ELCAP was 82%, and in the NLST it was 67% (P<0.0001). The frequency of stage I (pathologic and clinical if not resected) was 78% in I-ELCAP and 62% in the NLST (P<0.0001). Surgical resection was performed in 86% (664/755) in I-ELCAP and 76% (492/644, P<0.0001) in the NLST. The average tumor size was 17mm in I-ELCAP and 23mm in the NLST (P<0.0001). The 5-year survival rate was 83% in I-ELCAP and 62% in the NLST (P<0.0001). Cox regression showed that I-ELCAP provided a 50% better survival benefit than the NLST and that stage I and resection were key determinants of survival, independent of age, smoking history, and tumor size. The higher frequency of stage I disease and resection and smaller tumor size resulted in a significantly higher survival rate in I-ELCAP than in the NLST. These differences strongly support the importance of a specified regimen of screening, as alternative explanations have been addressed. © 2015 Wolters Kluwer Health, Inc. All rights reserved

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Unbalanced bilingual acquisition as a mechanism of grammatical change
No full textBilingual first language acquisition (BFLA) has been considered a possible mechanism of contact-induced change in several recent studies (Siegel, 2008, p. 117; Satterfield, 2005, p. 2075; Thomason, 2001, p. 148; Yip & Matthews, 2007, p.15). There is as yet little consensus on the question, with divergent views regarding both BFLA at the individual level and the implications for language change at the community level.published_or_final_versio
