Abstract:

This paper is an attempt to investigate the ideology of conservatism in Leonard Huxley’s Brave New World from critically. Huxley’s novel was selected for having the theme of conservatism. The study applies Van Dijk’s model (2006) to analyze how conservatives structure their speech, focusing on lexical, syntactic, and social categories. Thus, three levels of structures are investigated. The first level (microstructure) deals with lexical, syntactic, and rhetorical categories. The second level (macrostructure) deals with categories, like power, identity, and dominance in affect

Abstract:

In this paper, I analyze two clause combining strategies in Ossetic that exhibit mixed properties between coordination and subordination. I argue that the ‘mismatch approach’ proposed by Culicover & Jackendoff (1997) and Yuasa & Sadock (2002) is best suited to account for their properties. However, in order to adequately describe the behavior of these constructions in terms of the mismatch approach, appealing to three levels of grammar is required instead of two levels (syntax and semantics) discussed in previous works. This provides a clear argument in favor of models of grammar such

Abstract:

Two fundamental aspects of conceptual and linguistic structure are examined in relation to one another: organization into strata, each a baseline giving rise to the next by elaboration; and the conceptions of reality implicated at successive levels of English clause structure. A clause profiles an occurrence (event or state) and grounds it by assessing its epistemic status (location vis-à-vis reality). Three levels are distinguished in which different notions of reality correlate with particular structural features. In baseline clauses, grounded by “tense,” the profiled occurrence belongs to b

The occurrence, density, and age-class structure of endemic fish species were compared over a period of 24 months in three Nova Scotia streams of differing pH. The absence of acid-sensitive species and very low densities of fish characterized the stream with a pH range of 4.5–5.0. Fish densities were lower in the stream with a pH range of 4.7–5.4 than in the stream with a pH range of 5.6–6.3. Juvenile salmon and cyprinids were the most abundant species in the least acidic stream. Their densities were considerably lower in the stream with pH levels of 4.7–5.4, and the young age-classes of the c

Here we quantitatively analyze and compare the 3D structures of two types of genomic domains as defined by the human transcriptome map. While ridges are gene dense and show high expression levels, antiridges, on the other hand, are gene poor and carry genes that are expressed at low levels. We show that ridges are in general less condensed, more irregularly shaped, and located more closely to the nuclear center than antiridge

Two hundred and three children in China completed morpheme (homonym awareness) and structure awareness (lexical compounding) tasks across the three grades (M = 6.66, SD = .30 at the first time point). Results indicated that g

Abstract:

This paper aims to identify an optimum bone fracture stabilizer. For this purpose, three design variables including the ratio of the screw diameter to the plate width at three levels, the ratio of the plate thickness to the plate width at three levels, and the diameter of the bone at two levels were selected for analysis. Eighteen 3D verified finite element models were developed to examine the effects of these parameters on the weight, maximum displacement and maximum von Mises stress of the fixation structure. Considering the relations between the inputs and outputs using multivariate regress

Abstract:

The paper presents the results of a study of the relationship between the components of psychological well-being and perfectionism in students. Psychological well-being is a basic subjective construct that expresses a person’s perception and assessment of their functioning, taking into account the existing capabilities. Perfectionism is considered as a personal characteristic that may influence the overall and professional development of students. The description of the internal structure of perfectionism is based on a three-dimensional model of perfectionism developed by Paul L. Hewitt and Go

Abstract:

A social network is a platform that users can share data through the internet. With the ever-increasing intertwining of social networks and daily existence, the accumulation of personal privacy information is steadily mounting. However, the exposure of such data could lead to disastrous consequences. To mitigate this problem, an anonymous group structure algorithm based on community structure is proposed in this article. At first, a privacy protection scheme model is designed, which can be adjusted dynamically according to the network size and user demand. Secondly, based on the community char

Thiazolidinediones may slow the progression of type 2 diabetes by preserving pancreatic β-cells. The effects of pioglitazone (PIO) on structure and function of β-cells in KKA(y), C57BL/6J ob/ob, and C57BL/KsJ db/db mice (genetic models of type 2 diabetes) were examined. ob/ob ( n = 7) and db/db ( n = 9) mice were randomly assigned to 50-125 mg·kg body wt-1·day-1of PIO in chow beginning at 6-10 wk of age. Control ob/ob ( n = 7) and db/db mice ( n = 9) were fed chow without PIO. KKA(y) mice ( n = 15) were fed PIO daily at doses of 62-144 mg·kg body wt-1·day-1. Control KKA(y) mice ( n = 10) recei

Aim: This study revealed the relationship between the change in dynamic characteristics of structures damaged by exposure to extreme loads such as earthquakes, explosions, and impact and damage levels. Thus, a quick method can be used immediately after the damage has been proposed. Method: The studies consist of two parts, experimental measurements, and numerical solutions. For the analysis, a single degree of freedom, a four-column steel model structure was fabricated, and its free vibrations were recorded with the help of an accelerometer. Three scenarios are defined for the system no damage

Abstract:

Ignorance of spatial structures in fisheries management may lead to unexpected risks of overexploitation. Based on the information about small yellow croaker ( Larimichthys polyactis ) off the coast of China, we simulated a fish population consisting of three subpopulations mixing at intermediate levels, which was considered in the “true” spatial structure of the population in this study. Three scenarios of population spatial structure were assumed in assessing and managing this simulated fishery: (i) metapopulation, which has the same structure as the “true” population; (ii) three independent

Abstract The two leading principal components of the daily 850- minus 150-hPa global velocity potential in the Interim European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-Interim) (1979–2011) data are used as time-varying Madden–Julian oscillation (MJO) indices. Regression maps and meridional cross sections based on these indices are used to document the structure and evolution of the zonal wind (u) and geopotential height (Z) anomalies in the MJO cycle. The data are daily, and they are not separated by season. At upper-tropospheric levels the MJO signature is dominated
