No / Mobile phones have become an integral part of human lives with majority of people using them to access product and services for their day-today needs. However, mobile shopping adoption across the globe is not wide or fast as expected. In addition, the research is very scant in understanding various predictors of consumer adoption towards mobile shopping. The objective of this study is to identify most significant and non-significant predictors of consumer mobile shopping acceptance. Systematic review and weight analysis on 34 mobile shopping studies revealed researchers mostly employed TAM and UTAUT model as theoretical lens. This study found an interesting revelation that extrinsic motivation variables such as social influence and perceived usefulness determine consumer mobile shopping behavioral intention during early stages. However, in later stages intrinsic motivation variables such as satisfaction and trust play crucial role to emerge as best and promising predictor of consumer continuous intention respectively.

Yes / The purpose of this paper is to perform a weight-analysis and to undertake a meta-analysis of findings reported in published research on the adoption and diffusion of e-government. Usable data relating to e-government adoption research were collected from 103 empirical studies. Of those 103 articles, only 63 used a range of different constructs with appropriate correlation values required for performing a weight- and meta-analysis. Diagrammatic representation has been presented using significant as well as non-significant relationships from all 103 publications. A broader analysis of research on adoption and diffusion of e-government also reflects that although a large number of theories and theoretical constructs were borrowed from the reference disciplines, their utilization by e-government researchers appears to be largely random in approach. This paper also acknowledges the theoretical contribution, the limitations of this study, and suggests further research directions for the continued work.

The least mean square (LMS) algorithm is widely expected to operate near the corresponding Wiener filter solution. An exception to this popular perception occurs when the algorithm is used to adapt a transversal equalizer in the presence of additive narrowband interference. The steady-state LMS equalizer behavior does not correspond to that of the fixed Wiener equalizer: the mean of its weights is different from the Wiener weights, and its mean squared error (MSE) performance may be significantly better than the Wiener performance. The contributions of this study serve to better understand this so-called non-Wiener phenomenon of the LMS and normalized LMS adaptive transversal equalizers. The first contribution is the analysis of the mean of the LMS weights in steady state, assuming a large interference-to-signal ratio (ISR). The analysis is based on the Butterweck expansion of the weight update equation. The equalization problem is transformed to an equivalent interference estimation problem to make the analysis of the Butterweck expansion tractable. The analytical results are valid for all step-sizes. Simulation results are included to support the analytical results and show that the analytical results predict the simulation results very well, over a wide range of ISR. The second contribution is the new MSE estimator based on the expression for the mean of the LMS equalizer weight vector. The new estimator shows vast improvement over the Reuter-Zeidler MSE estimator. For the development of the new MSE estimator, the transfer function approximation of the LMS algorithm is generalized for the steady-state analysis of the LMS algorithm. This generalization also revealed the cause of the breakdown of the MSE estimators when the interference is not strong, as the assumption that the variation of the weight vector around its mean is small relative to the mean of the weight vector itself. Both the expression for the mean of the weight vector and for the MSE estimator are analyzed for the LMS algorithm at first. The results are then extended to the normalized LMS algorithm by the simple means of adaptation step-size redefinition. / Ph. D.

No / Electronic word of mouth (eWOM) significantly affects the consumer decision-making process. A number of studies investigated why consumers provide eWOM communications. Existing literature has contradicting factors regarding factors affect eWOM providing behaviour. This study aims to evaluate factors affecting eWOM providing behaviour by performing a systematic review and weight analysis of existing research outputs. Based on the result of weight analysis it was found that the best predictors of eWOM providing behaviour are involvement, self-enhancement, and trust in web eWOM services. Scholars can use the results of this study when making decisions regarding the inclusion of factors in their research. Practitioners can pay more attention to the best predictors.

Yes / Purpose – The purpose of this paper is to perform a systematic review of articles that have used the unified theory of acceptance and use of technology (UTAUT). Design/methodology/approach – The results produced in this research are based on the literature analysis of 174 existing articles on the UTAUT model. This has been performed by collecting data including demographic details, methodological details, limitations, and significance of relationships between the constructs from the available articles based on the UTAUT. Findings – The findings indicated that general purpose systems and specialized business systems were examined in the majority of the articles using the UTAUT. The analysis also indicated that crosssectional approach, survey methods, and structural equation modelling analysis techniques were the most explored research methodologies whereas SPSS was found to be the largely used analysis tools. Moreover, the weight analysis of independent variables indicates that variables such as performance expectancy and behavioural intention qualified for the best predictor category. Moreover, the analysis also suggested that single subject or biased sample as the most explored limitation across all studies. Research limitations/implications – The search activities were centered on occurrences of keywords to avoid tracing a large number of publications where these keywords might have been used as casual words in the main text. However, we acknowledge that there may be a number of studies, which lack keywords in the title, but still focus upon UTAUT in some form. Originality/value – This is the first research of its type which has extensively examined the literature on the UTAUT and provided the researchers with the accumulative knowledge about the model.

Yes / In the last few years, several studies have examined the predictors of mobile banking (m-banking) adoption using the unified theory of acceptance and use of technology (UTAUT). However, contradictory results in some of the UTAUT relationships were found in the existing literature. Therefore, we aim to clarify and synthesize the empirical findings from the m-banking studies published since 2004 by conducting weight and meta-analysis with a focus on the UTAUT theory. We also seek to identify the roles of moderating variables on each UTAUT path. A total of 364 path coefficients from 127 studies were relevant for data analysis. CMA software V3 was employed to combine the effect sizes. All UTAUT relationships were found to be significant. Performance expectancy emerged as the strongest antecedent of usage intention. We also find that usage intention is the most critical predictor of use behavior. It was also revealed that sample size and culture significantly moderated the linkages between facilitating conditions and usage intention, effort expectancy and usage intention, and usage intention and use behavior. Theoretical contributions and managerial implications are also discussed toward the end.

The problematics of preliminary verification of flight performances as well as aircraft dimension design and follow-up weight analysis with consideration of power cells placement is described thereafter. A few different flight configurations is taken into consideration within weight analysis. Final part contains evaluation of optimization and design process.

Dans le domaine de l’anthropologie funéraire, les analyses en ostéologie quantitative constituent l’approche préalable nécessaire à la compréhension d’un gisement car elles informent quant à la composition de la population exhumée. Appliquées à des assemblages osseux livrant un grand nombre de restes, fragmentés et intriqués dans une sorte de désordre anatomique, ces études sont délicates. Par définition, les gisements concernés sont donc les sépultures collectives, a fortiori s’il existe des dépôts secondaires. A travers l’estimation du nombre minimum de sujets (NMI) présents dans le niveau chalcolithique de la sépulture collective du dolmen des Peirières (Aude, France), ces travaux ont pour objectif de mettre en évidence les problèmes théoriques relatifs à l’ostéologie quantitative, que ce soit du point de vue des méthodes ou de l’application de ces dernières, ainsi que les régions anatomiques les plus pertinentes pour le décompte des sujets à partir de séries fragmentées. Afin de mener cette réflexion, l’estimation du NMI se fonde d’une part sur les méthodes classiques de dénombrement des assemblages osseux et dentaires, d’autre part sur l’analyse pondérale, méthode utilisée dans le cas de sépultures à incinération. Il ressort que le caractère qualitatif d’un assemblage conditionne les résultats de l’analyse quantitative. La confrontation des NMI et des indices pondéraux montre que la fragmentation conduit à des profils ostéologiques particuliers. Dans de tels cas de figure, un choix de régions anatomiques précises et une systématisation des analyses pondérales se révèlent donc indispensables pour la bonne interprétation des résultats. Il apparaît également que les concepts de l’ostéologie quantitative, tels qu’ils sont définis à l’heure actuelle, sont difficilement transposables à des assemblages osseux extrêmement fragmentés. Enfin, une série de comparaisons des résultats obtenus sur quelques sépultures collectives de la même période semble indiquer une redondance quant à la pertinence de certaines parties du squelette en terme de dénombrement. / In the field of funerary anthropology, the quantitative osteology analysis constitute a preliminary approach necessary to the comprehension of a deposit because they inform on the composition of the exhumed population. Applied to osseous gatherings giving a great number of remains, split up and intricate in a kind of anatomical disorder, these studies are difficult to handle. By definition, the deposits concerned are thus collective burials, a fortiori if there are secondary deposits. Through the estimate of the minimum number of subjects (MNI) present in the chalcolithic level of the collective burial of the dolmen of Peirières (Aude, France), this work aims at highlighting the theoretical problems related to quantitative osteology, that is from the point of view of the methods or the application of these, as well as the anatomical areas most relevant to the counting of the subjects starting from fragmented series. In order to carry out this work, the NMI estimations are based on the traditional methods of counting of the osseous and dental gatherings on the one hand, on the ponderal analysis on the other hand, method used in the case of incinerations. It appears that the qualitative character of a deposit conditions the results of the quantitative analysis. NMI and ponderal indices confrontation show that fragmentation led to particular osteological profiles. In such cases, a choice of precise anatomical areas and a systematization of ponderal analysis thus appear essential for a sound interpretation of the results. It also appears that the concepts of quantitative osteology, such as defined, are not easily applicable to extremely fragmented osseous deposits. Eventually, a series of comparisons of the results from some collective burials of the same period seems to point to a redundancy as far as numbers are concerned or the relevance of certain parts of the skeleton in term of counting.
