35,90 € *
ggf. zzgl. Versand

The intention of writing this book is to give a basic knowledge regarding AMOS software which is a software package capable in finding complex relationships, popular as structural equation modeling (SEM). Today many researchers are interested in finding out such a complex relationships and AMOS software is becoming popular in this purpose. Hence, this book will be helpful to the beginners of SEM as it is a guide book for developing and identifying number of interconnected relationships through complex models.

During the last two decades, structural equation modeling (SEM) has emerged as a powerful multivariate data analysis tool in social science research settings, especially in the fields of sociology, psychology, and education. Although its roots can be traced back to the first half of this century, when Spearman (1904) developed factor analysis and Wright (1934) introduced path analysis, it was not until the 1970s that the works by Karl Joreskog and his associates (e. g. , Joreskog, 1977, Joreskog and Van Thillo, 1973) began to make general SEM techniques accessible to the social and behavioral science research communities. Today, with the development and increasing avail ability of SEM computer programs, SEM has become a well-established and respected data analysis method, incorporating many of the traditional analysis techniques as special cases. State-of-the-art SEM software packages such as LISREL (Joreskog and Sorbom, 1993a,b) and EQS (Bentler, 1993, Bentler and Wu, 1993) handle a variety of ordinary least squares regression designs as well as complex structural equation models involving variables with arbitrary distributions. Unfortunately, many students and researchers hesitate to use SEM methods, perhaps due to the somewhat complex underlying statistical repre sentation and theory. In my opinion, social science students and researchers can benefit greatly from acquiring knowledge and skills in SEM since the methods-applied appropriately-can provide a bridge between the theo retical and empirical aspects of behavioral research.

Magnetic Nanowires

ggf. zzgl. Versand

Magnetic nanostructures have attracted increasing attention because of their potential applications in high-density data storage and in sensor technology. An understanding of the fundamental physical properties of these nanostructures is of interest in the study of atomic structures and micromagnetism. This book presents a study on the growth of nickel nanowires in commercially available templates. Electrodeposition was used through the pores of a template to produce nanowire matrices. Dependence of the nanowire growth rate, quality of deposit, growth uniformity, crystal orientations and other physical properties of the nanowire network were studied using various process parameters. Structural properties of the nanowire were characterised using AFM, SEM, EDX and TEM. Magnetic properties of the nanowires were studied using a VSM and MFM. Using OOMMF software magnetic behaviour of the nanowires was simulated and compared with the experimental coercivity values and magnetisation behaviour. The target audience of this book is the postgraduate students and the researchers who would like to study the fabrication and characterisation of magnetic nanowires.

The main purpose of this research work is to develop the single domain magnetic particles of M-type Barium hexa-ferrite having composition of BaFe12O19 using oxide precursors using conventional powder metallurgy technique. The phase formation and magnetic performance of the powders and magnets will be optimized by adjusting calcination and sintering temperatures. The synthesis of M-Type Barium hexa-ferrite carried out in two sections. A series of four samples have been prepared by initial wet mixed powders calcined at different temperatures i.e. 750, 850, 950 and 1050oC. On the basis of structural analysis the sample calcined at 950oC has been selected and further divided into four parts to sintered them at 1100, 1150, 1200 and 1250oC. These are characterized through Differential Scanning calorimetric (DSC), X-ray Diffractometer (XRD), Diamond Structure visualization software, Fourier transform infrared (FTIR), Scanning electron microscope (SEM) and DC-Magnetometer. The structural measurements depict the confirmation of M-Type Barium Hexa-ferrite structure. SEM micrographs show the hexagonal shaped like grains. The coercivity of the sample sintered at 1250oC has a minimum value.

This compact reference surveys the full range of available structural equation modeling (SEM) methodologies. It reviews applications in a broad range of disciplines, particularly in the social sciences where many key concepts are not directly observable. This is the first book to present SEM's development in its proper historical context-essential to understanding the application, strengths and weaknesses of each particular method. This book also surveys the emerging path and network approaches that complement and enhance SEM, and that will grow importance in the near future. SEM's ability to accommodate unobservable theory constructs through latent variables is of significant importance to social scientists. Latent variable theory and application are comprehensively explained and methods are presented for extending their power, including guidelines for data preparation, sample size calculation and the special treatment of Likert scale data. Tables of software, methodologies and fit statistics provide a concise reference for any research program, helping assure that its conclusions are defensible and publishable.

The output of this research is framework that informs the adoption of Software as a Service (SaaS) for Small and middle-sized businesses (SMEs). Recent research has shown that there are significant advantages of SaaS when adopted by SMEs. The author investigated SMEs in different sectors on a weighting proposal. This target was 87% in excess of the required minimum of 200 respondents as required by Structural Equation Modeling (SEM) which was done using SPSS AMOS focused on modeling, trimming and best fit. However 293 respondents were obtained, which was significantly above the minimum requirement. The findings indicated that the factors that significantly influence the adoption of SaaS by SMEs include: awareness, trust, prior IT experience, relative advantage, triability, ICT knowledge and skills, top level management support and complexity. The researcher was able to recommend firstly, that evaluation of the market is critical for SaaS deployment and finally, that application developers, technological consultants, software vendors, and policy makers that intend to adopt SaaS should consider the extended TOE model developed from this research.
