Topic structures and minimal effort

The complexity of human languages has always inspired research for some human faculty that makes language learning possible. The system that generates the complexity of human languages, ideally, is simple and effective. Recent developments of the generative grammatical theory explore deeper into the issue of simplicity or economy. The Minimalist Program developed in Chomsky (1991, 1993, 1995) tries to provide contents to such notions. What does it mean to be more economic or least effort? An important instantiation of such notions is the proposal that movement is the last resort assuming that movement is more costly than non-movement. Processes occur only because they are necessary. The definition of necessity generally is cast in morphological terms. Moreover, the notion of "economy" or "least effort" is deterministic of the appropriate derivations for sentences: a shorter derivation is better than a longer one. In this work, we show that the notion of "least effort," - do minimally if possible - is manifested not only in derivations but also in other aspects of the grammar. We take Chinese as an example and show that this language exhibits the properties manifesting some "least effort" guidelines in the area of movement and reconstruction, and in the projection of syntactic positions: when there is a choice, non-application of moyement/reconstruction and non-projection of a position are adopted. These phenomena essentially are attested in topic structures. The question arises as to why topic structures exhibit such minimal effort effects. We suggest that this is due to the fact that topic structures can be derived by movement or base-generation. When there are morpho-syntactic clues that reconstruction is necessary, the structure is a movement structure. Otherwise, the less costly non-movement structure is assumed. Moreover, because of the possibility of assuming a topic NP to be base-generated, bearing a predication (or aboutness) relation with the comment clause, the argument position which otherwise would be related to the topic (conveniently termed the trace position) is not projected when there is a choice of projecting or not projecting it

Functional Structure(s), Form and Interpretation

The issue of how interpretation results from the form and type of syntactic structures present in language is one which is central and hotly debated in both theoretical and descriptive linguistics. This volume brings together a series of eleven new cutting-edge essays by leading experts in East Asian languages which shows how the study of formal structures and functional morphemes in Chinese, Japanese and Korean adds much to our general understanding of the close connections between form and interpretation. This specially commissioned collection will be of interest to linguists of all backgrounds working in the general area of syntax and language change, as well as those with a special interest in Chinese, Japanese and Korean

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

Thematic Hierarchy and Derivational Economy*

What thematic hierarchy is has been controversial, and whether it should exist as a theoretical construct has been questioned. This work shows that if thematic hierarchy is represented structurally as layers of projections, it helps to account for some newly observed constraints on object deletion in Chinese. Chinese exhibits much flexibility in the number and type of arguments that can occur with verbs, and subjects and objects seem to be interchangeable in many cases. However, it is shown that constraints can be found amid the great flexibility in argument structure-object deletion is not possible in the cases not following thematic hierarchy, although subject deletion is still possible. Moreover, object deletion is unacceptable in the cases where arguments are added syntactically. Again, subjects can be deleted in such constructions. These generalizations will be captured by the aforementioned layers of projections reflecting thematic hierarchy and a notion of derivational economysimpler structures are favored when choices are available

Sluicing, Sprouting and Missing Objects

Taking “sluicing” to be derived by movement + deletion, as represented by Merchant (2001), and “pseudo-sluicing” to be a base-generated structure [pro (+be) + wh] (going by Wei 2004; Adams 2004), this paper reviews arguments for and against the presence of a sluicing construction in Mandarin Chinese. We show that all the tests available in the literature do not argue against the presence of such a sluicing construction, except the test building on the distribution of the copula shi. Unfortunately, the shi test is demonstrated to be uncertain and it cannot be used to argue conclusively that only a base-generation pseudo-sluicing analysis should be adopted. We show that a much clear evidence for an exclusive pseudo-sluicing analysis comes from the behavior of the sprouting construction. Investigation of sprouting also sheds light on the properties of null arguments, topic-variable relation, locality, and subcategorization of verbs in the language
