scholarly journals A comparative approach to verbal morphology in Transeurasian

Author(s):

This chapter starts from a point of consensus in the Transeurasian debate, namely that common paradigmatic morphology could substantially help unravel the question. It aims at giving an overview of the verbal morphology shared by the Transeurasian languages. In addition to regular correspondences in form and function, it argues that the Transeurasian verb morphology displays a certain degree of paradigmaticity, based on relationships of grammatical patterning among different morphosyntactic subsystems. Moreover, shared irregularities such as peculiar allomorphies and functional idiosyncrasies are taken as a strong indication of affiliation of the languages concerned. The chapter concludes with an assessment of chance similarity, leading to the viewpoint that it is more sensible to attribute the correlations in the verbal morphology to inheritance than to take refuge in non-genealogical explanations.

Several snake species that feed infrequently in nature have evolved the ability to massively upregulate intestinal form and function with each meal. While fasting, these snakes downregulate intestinal form and function, and upon feeding restore intestinal structure and function through major increases in cell growth and proliferation, metabolism and upregulation of digestive function. Previous studies have identified changes in gene expression that underlie this regenerative growth of the python intestine, but the unique features that differentiate this extreme regenerative growth from non-regenerative post-feeding responses exhibited by snakes that feed more frequently remain unclear. Here, we leveraged variation in regenerative capacity across three snake species—two distantly related lineages ( Crotalus and Python ) that experience regenerative growth, and one ( Nerodia ) that does not—to infer molecular mechanisms underlying intestinal regeneration using transcriptomic and proteomic approaches. Using a comparative approach, we identify a suite of growth, stress response and DNA damage response signalling pathways with inferred activity specifically in regenerating species, and propose a hypothesis model of interactivity between these pathways that may drive regenerative intestinal growth in snakes.

In some researchs of settlement archeology in Indonesia, such as the Trowulan site in Mojokerto or Liangan site in Temanggung, until now still not much gained an overview of significant regarding the spatial pattern layout of the building, as well as the shape of the building houses in the two these sites. Whereas This paper describes an overview of how the spatial pattern of settlements, especially the spatial patterns of the building, the shape of the houses and their functions in Desa Adat Pengotan, Bali. Traditional Village Pengotan chosen because this village has unique characteristics that differ from other indigenous villages in the district of Bangli, Bali Province. The method applied is ethnoarchaeology studies, through a general comparative approach to the methods and techniques of work through the interview, descriptive and interpretative. The results of research in the form of images and spatial models of settlements, especially the spatial patterns associated with building houses or other buildings that are interconnected, along with the form and function of use and wear, both profane and sacred of Desa Adat Pengotan in Bali. These results that can later be used as we examine the comparability of the archaeological sites of settlements.  ABSTRAKPada beberapa penelitian arkeologi permukiman (settlement archaeology) di Indonesia, seperti Situs Trowulan di Mojokerto atau Situs Liangan di Temanggung, hingga saat ini masih belum banyak diperoleh gambaran yang signifikan mengenai pola tata ruang, tata letak bangunan, serta bentuk bangunan rumah yang berada di kedua situs tersebut. Tulisan ini memaparkan gambaran bagaimana pola tata ruang permukiman, terutama pola tata ruang bangunan, bentuk rumah-rumah beserta fungsinya di Desa Adat Pengotan, Bali. Dipilihnya Desa Adat Pengotan dikarenakan desa ini memiliki keunikan tersendiri yang berbeda dengan desa-desa adat lainnya di wilayah Kabupaten Bangli, Provinsi Bali. Adapun metode yang diterapkan adalah studi etnoarkeologi, melalui pendekatan general comparative dengan metode dan tehnik kerja melalui wawancara, deskriptif dan interpretatif. Hasil penelitian berupa gambaran dan model tata ruang permukiman, terutama pola tata ruang yang berkaitan dengan bangunan rumah atau bangunan lainnya yang saling berhubungan, berserta bentuk dan fungsi guna dan pakai, baik bersifat profan maupun sakral dari Desa Adat Pengotan di Bali. Hasil ini yang nantinya dapat digunakan sebagai data banding dalam kita meneliti situs-situs arkeologi permukiman.

STM is one of the most promising techniques available for visualizing the fine details of biomolecular structure. It has been used to map the surface topography of inorganic materials in atomic dimensions, and thus has the resolving power not only to determine the conformation of small molecules but to distinguish site-specific features within a molecule. That level of detail is of critical importance in understanding the relationship between form and function in biological systems. The size, shape, and accessibility of molecular structures can be determined much more accurately by STM than by electron microscopy since no staining, shadowing or labeling with heavy metals is required, and there is no exposure to damaging radiation by electrons. Crystallography and most other physical techniques do not give information about individual molecules.We have obtained striking images of DNA and RNA, using calf thymus DNA and two synthetic polynucleotides, poly(dG-me5dC)·poly(dG-me5dC) and poly(rA)·poly(rU).

Going along with the end of the “golden age” of the welfare state, the fordist paradigm of social housing has been considerably transformed. From the 1980s onwards, a new paradigm of social housing has been shaped in Germany in terms of provision, institutional organization and design. This transformation can be interpreted as a result of the interplay between the transformation of national welfare state and housing policies, the implementation of entrepreneurial urban policies and a shift in architectural and urban development models. Using an integrated approach to understand form and function of social housing, the paper characterizes the new paradigm established and nevertheless interprets it within the continuity of the specific German welfare resp. housing regime, the “German social housing market economy”.
