Rapid proliferation in the business potential of mobile marketing attracts researchers from various fields to contribute to the growing body of knowledge on the phenomena. Although the literature on mobile marketing is accumulating, the stream of research is still in the development stage, hence is highly inconsistent and fragmented. This paper aims to organize and classify the literature on mobile marketing and assess the-state-of-the-art in order to facilitate future research. The review covers 255 peer-reviewed journal articles from 82 journals published between 2000 and 2008. The resulting framework summarizes the progress in mobile marketing research and provides future research directions.  相似文献

This two-group quasi-experimental study investigated the effects of the Online Advance Organizer Concept Teaching Material (ONACOM) integrated with inquiry teaching and expository teaching methods. Grade 7 students’ posttest performances on the light unit achievement and light unit attitude tests controlled for gender, previous semester science grade, and pretest scores were analyzed. No significant treatment effects were found between the inquiry and expository approaches. However, both groups demonstrated significant pretest–posttest gains in achievement and attitude. Independent from the method used, ONACOM was judged effective in both groups as students demonstrated increased achievement and attitude scores. ONACOM has a social and semantic network-aided infrastructure that can be adapted to both methods to increase students’ achievement and improve their attitude.  相似文献

This study investigates the mental model comparison between expert and novice performance improvement practitioners. Nonexperimental survey research design was applied. Based on specific criteria, 11 critical concepts out of 30 were selected by 23 experts. Sixteen of those 23 experts provided data about the relatedness of 55 concept‐pairs generated from the 11 concepts to develop the common mental model of experts in the Knowledge Network Organizing Tool utilizing Pathfinder scaling. Two‐hundred‐forty‐two practitioners participated in the further phases of the study. Out of those practitioners, 33 novices, who have not met any of the criteria used for expert selection, are selected. Those novices also provide similar data for the common mental model of novices. The results of the study show that the expert model has more consistent and hierarchical structure than the novice model. Discussions and further research recommendations are provided.  相似文献

This paper reports findings of a study designed to test whether differences in spatial layout of research offices and labs (workspace planning) affects face-to-face technical consultations, and ultimately innovation process outcomes in research settings critical to government supported innovation strategies—university research centers (URCs). The study involved a mixed-method (multivariate predictive and multiple case comparison) evaluation of six organizationally similar but spatially different URCs. Data analysis revealed relationships between workspace planning, consultations and innovation process outcomes. Multivariate analyses showed that configurational accessibility, visibility and walking distances significantly affect the frequencies and locations of unprogrammed face-to-face consultations. Cross-case comparisons revealed that URCs featuring overall high configurational accessibility, shorter walking distances and intact territories exhibit higher face-to-face consultation rates, consultation network connectivity, and subjective/objective innovation process outcomes. Implications for research policy, practice and research are discussed.  相似文献

It is advantageous to use the substructural and/or decentralized techniques in structural control to save on computations and time. In this paper, a generalized substructural approach is presented in the control of fuzzy nonlinear flexible structures with discrete sensors/actuators. The substructural control scheme is developed using the static condensation technique together with the LQG control method. The subcontrollers and subobservers designed at substructure levels are used to assemble the global controller and observer for the whole structure. Nonlinear effects are included in the structural formulations and a fuzzy methodology is adopted for handling the imprecision present in the structure modeling. The nonlinear and fuzzy schemes are applied to one structural control problem to illustrate the accuracy and capability of the substructural control technique.  相似文献
