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

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.

Furthermore, recent evidence suggests that archaic introgressed material could have been biologically relevant for modern humans to adapt to new environments.

This study compared 3 approaches for handling a fourth level of nesting structure when analyzing data from a cluster-randomized trial (CRT). CRTs can include 3 levels of nesting: repeated measures, individual, and cluster levels. However, above the cluster level, there may sometimes be an additional potentially important fourth level of nesting (e.g., schools, districts, etc., depending on the design) that is typically ignored in CRT data analysis. The current study examined the impact of ignoring this fourth level, accounting for it using a model-based approach, and accounting it using a desi

James Tenney reflects on form in twentieth-century music, first by offering an alternative to the conventional definition of form and introducing a number of new terms. He then considers three factors that determine form: shape, structure, and state. In relation to these factors, he describes three aspects of form to consider at each hierarchical level: the structural (internal relations), the morphological (shape), and the statistical (state, condition). These relations between state, shape, and structure at adjacent hierarchical levels are relevant to the old problem of “form versus content.

Abstract:
Function models are used during the conceptual design phase of the design process to model the intended use or objective of a product, independent of the products physical form. Function models also aid in guiding design activities such as generating concepts and allocating design team resources. Recent research effort have focused on the formalization of function models through a controlled vocabulary and archival of functional representations in computer-based repositories. However, the usefulness and interpretability of these function models has not fully been explored. This paper presents

Abstract:
A CFD solver CFX is used to analyze the complex behavior of turbulent reacting flow inside the furnace. The flow characteristics for various combustor geometries, fuel/air ratios, and injection velocities, and swirl levels are investigated. Starting with a cylindrical furnace fired with gaseous fuel from a concentric tube burner (both with and without swirl), the mixture-fraction is predicted using the k-ε and RSM turbulence models. The discrepancies between the predictions and measurements are most significant in the flame core of upstream regions. It may stem from inappropriateness of the as

Abstract:
Using state-of-the-art optical technologies, such as holographic three-dimensional interconnect and optical disk storage, a novel optoelectronic programmable data-base ma chine for storing, processing, and reconstructing three-dimensional solid objects is proposed. The so-called edge-based boundary model that represents a three-dimensional object by its faces and edge sequence is used as the data structure. For efficient optical storage and processing, this data structure is further decomposed into three levels: a face, an edge, and a vertex level. Each decomposed level is encoded into a set o

Abstract:
Many companies that struggle with product variety and configuration management issues turn to a module-based design approach. Although this approach is well-known to be efficient for managing variety of a product family, current methods do not enable designers to handle both modularity and variety within a product family. The Design Structure Matrix (DSM) has been widely used to identify modules within a product, but its use to identify modules across a family of products has been limited. In this context we propose two tools based on an extension of the basic DSM to manage variety of an entir

In this study, in order to investigate wave force and wave-induced overturning moment according to the support structure types and sea levels, wave force tests were carried out for the three offshore support structures of Monopile, GBS, and Hybrid under three sea levels of HSWL, MSL, and LSWL. As the results of this study, it was found that, as the wave height increased at the shallow water (LSWL), wave force increased significantly because of the wave nonlinearity, named wave shoaling. Also, as the structural member size became larger, wave nonlinearity effects on wave force at the shallow wa

These components generate steam at three different pressure levels, used to produce additional work in one steam turbine. The productive structure of the considered system is used to visualize the cost formation process as well as the productive interaction between their components. The exergoeconomic analys

Abstract:
Modern film cooling is an essential method to protect the turbine blade from the hot gas, and the issue about how to improve the film cooling performance has attracted much attention. In this study, a tree-shaped film cooling structure is carried out to improve the overall effectiveness and better decrease the metal temperature of the blade at the same time. To validate the superiority of the proposed structure, a series of numerical simulation cases are conducted under a typical blowing ratio of M = 0.764. The first case is a film cooling channel with a single film hole which with a diameter

Abstract:
The Inner Harbor Navigation Canal (IHNC) Lock connects the Mississippi River to the Gulf Intracoastal Waterway, surrounded by developed areas in New Orleans, Louisiana. Tow transit times through the current IHNC lock take up to 20 hours. The US Army Corps of Engineers, New Orleans District, has proposed constructing a new lock to reduce tow transit times significantly. However, the new lock will have potential effects on vehicle traffic patterns due to the three bridges across IHNC.

Abstract:
Jamaica seems to be a puzzling case for economic growth: despite the structural reforms implemented in the last three decades and adequate investment levels, real GDP per capita is roughly the same as in 1970. The disappointing performance of this economy suggests that productive development policies (PDPs), including first-generation reforms, have not been enough to create a better environment for productivity growth. This paper examines the PDPs in Jamaica and concludes that behind the paradox of high investment and low growth of this economy are the "public debt trap" and a highly distortiv
