Have went– an American usage problem

Have wentmay seem a straightforward non-standard grammatical form today, but it evidently has a different status in British and American English. While in British English it developed into a non-standard form after the codification of the strong verb system by the eighteenth-century normative grammarians, in American English it became a usage problem. This we concluded from its appearance primarily in usage guides published in the United States over the years. The current status of the variant in the region was confirmed by evidence we encountered both in anonymous surveys and in face-to-face interviews with native speakers of American English. Our findings for the differences in status ofhave wentin the course of its history were supported by corpus-based analyses of historical and modern text corpora for British and American English, while a close analysis of selected modern instances ofhave wentandhave goneshowed a different distribution between the two that appears to warrant a perceived difference in meaning noted by some of the American informants.

Cell Phoning and Texting While Driving

A qualitative phenomenological study was conducted on the consequences of cell phone use while operating a vehicle. We discussed why talking and texting on cell phones are so popular through the analysis of our interviews with police officers, driving instructors, and parents of teens and young adults. The participants came from central, northeastern, northwestern, and southeastern Connecticut. All had exposure with respect to the effects of cell phone usage problem. The study reached a point of theoretical saturation or redundancy by which the analysis no longer resulted in new themes. We concluded that the discoveries revealed the necessity for education, expansion of technology, and additional driver education preparation, which may provide a path for leadership to help solve the problem.

Methods of raising telecommunication system effectiveness by using atomic function envelope approximation

Cellular and satellite data transmission systems are the most perspective directions of telecommunications development. Solution of the available spectral band effective usage problem with minimal energy costs is pracically important for these systems. This article describes the best practices of space-frequency signal filtering by antenna technology methods, applying a multiple spatial channels for information transmitting and methods of generating spectrally efficient signals based on finite differential equations solutions with offset argument. Methods of construction both direct and quadrature receive information systems with interference were proposed.

PERFORMANCE OF MYOPIC POLICY FOR MULTI-CHANNEL DYNAMIC SPECTRUM ACCESS NETWORKS

To solve inefficient spectrum usage problem under current static spectrum management policy, various kinds of dynamic spectrum access strategies have appeared. Myopic policy, which maximizes immediate throughput, is a simple and robust strategy with reduced complexity. In this paper, we present a simple mathematical model to evaluate the saturation throughput and medium access delay of a myopic policy in the presence of multiple channels.

Establishment of a Bacterial Expression System and Immunoassay Platform for the Major Capsid Protein of HcRNAV, a Dinoflagellate-Infecting RNA Virus

HcRNAV is a small icosahedral virus that infects the shellfish-killing marine dinoflagellate Heterocapsa circularisquama, which harbors a dicistronic linear single-stranded RNA (ssRNA) genome ca. 4.4 kb in length. Its major capsid protein (MCP) gene sequence is not expressed by various strains of Escherichia coli, possibly because of a codon usage problem. To solve this problem, a chemically modified (i.e., de novo synthesized) gene was designed and cloned into the pCold-GST expression vector, and transformed into E. coli strain C41 (DE3), in which codon usage was universally optimized to efficiently express the polypeptide having the viral MCP amino acid sequence. The bacterially expressed protein, which was purified after a procedure involving denaturation and refolding, successfully formed virus-like particles that significantly resembled native HcRNAV particles. The purified, denatured protein was used as an antigen to immunize rabbits, and the resulting antiserum was shown to be strongly reactive to not only the bacterially expressed recombinant protein, but also to native HcRNAV MCP by Western blotting and dot immunoassays, respectively. These results indicate that an antiserum recognizing native HcRNAV MCP was successfully obtained using bacterially expressed HcRNAV MCP as the antigen.

The “dual usage problem” in the explanations of “joint attention” and children’s socioemotional development: A reconceptualization

The term “joint attention”, which first gained currency in the early 1960s in studies of the development of language and symbolic thought, remains significant in the developmental literature. However, its meaning is unclear. A definitional problem exists similar to what Patterson [Patterson, M. L. (1982). A sequential functional model of nonverbal exchange. Psychological Review, 89, 231–249] described as the “dual usage” problem in the study of behaviour. The dual usage problem manifests when the behaviours of interest are used interchangeably with the function served by those behaviours. Similarly, the behaviours or skills that are taken to show joint attention are used interchangeably with the functions served by these behaviours. Scant attention is given to how the behaviours are generated and regulated and how they contribute to development. The purpose of the present position paper was: (1) to identify and illustrate the ways in which the behaviours and functions of joint attention have been confounded in the literature; (2) to provide a revised operationalization of joint attention incorporating the idea of Consummative Joint Attention, which is defined as a process variable that integrates these two theoretically different and complementary aspects of “joint attention;” and (3) to test this revised definition with evidence from a sample of hearing mothers and their 18- to 36-month-old hearing or deaf toddlers. We suggest that a reconceptualization and revised definition of joint attention as a process served by a particular sequence of complementary and well-timed events in the behaviour of mother–child interaction are particularly well-suited to testing joint attention as an early prelingual mechanism and to detecting early problems with psychosocial and adaptive development created by ineffective patterns of social interaction.

Forest landscape ecology and its applications in China

Landscape ecology is playing an increasingly important role in resources management and landuse planning in recent decades and attracting much attention from resource managers and scientists in China as well as in the world. Reviews of landscape ecology development in China have been well documented, whereas forest landscape ecology and its applications receive relatively fewer reviews. In this paper, we first present a brief review of the historical development and current advances of landscape ecology in China and then introduce the applications of landscape ecology to forest park designs, urban greenspace planning, ecological restoration, biodiversity conservation and forest eco-hydrology. Finally, the problems with the application of forest landscape ecology in China, such as inadequate synthesis and integration, lack of basic research on patterns and processes, basic data shortage and model usage problem are discussed on the basis of which we suggest a future direction of forest landscape ecology in China.

Marketing information system utilization: An application of self-concept theory

The impact of marketing information systems (MIS) has not been substantial and developed systems have not been highly utilized. Borrowing the theory of self-concept from the behavioral sciences, 46 system users' self-images, ideal self-images, and the images of a significant other (one who facilitates usage of the MIS) are measured and related to the image of a heavy user of the information system. The results shed some light on the system usage problem and provide some direction for marketing the MIS to marketing managers/ system users.
