E-government needs to be successfully implemented and assimilated into organizations to take advantage of its potential values and benefits for organizations. This study examines factors for e-government assimilation in Indonesia and employs the TOE (Technology-Organization-Environment) framework to develop a theoretical model to explain e-government assimilation. It also investigates how organizational type (central vs. local) plays a role in the assimilation of e-government. One hundred eighteen respondents from the central and local governments in Indonesia participated in the survey and an in-depth analysis based on partial least squares (PLS) was carried out. The results show that ICT infrastructure has the strongest significant relationship with e-government assimilation, Top management support, regulatory environment, ICT expertise, and competitive environment are also significant factors to explain e-government assimilation in Indonesia. Central and local governments Significantly differ in terms of e-government assimilation, so organizational type can be a moderator in the process of e-government assimilation. These findings present the efficacy of the proposed model for analyzing e-government assimilation and contribute additional insights for academia as well as practitioners and policy makers.

Assimilation is defined as the extent to which the use of a technology diffuses across organizational work processes and becomes routinized in the activities associated with those processes. Assimilation is an important construct in the casual chain of influence from the organizational adoption of an information technology to the evidence of its impacts on business performance. Given a wide range of experiences with the effective assimilation of Web technologies. there is a need to discover how firms can institutionally encourage the managerial activities that will result in greater levels of technology assimilation. This study analyzes or shows which organizational and strategical factors like management belief. management participation. strategic investment rationale and coordination mechanism have impact on the assimilation of web technologies. Moreover. this research is tried under the different types of firms. manufacturing and service firms. The result shows that the management belief among the determinants had a significant effect on the assimilation of web technology. However. the result would be generalized with the inclusion of the psychological factors to the current model.

This study investigates the effect of technological and environmental factors on the cloud computing assimilation, which then affects firms' performance. The technological characteristics include cost-savings, technology use advantage, technology infrastructure, and technology compatibility while environmental characteristics include partner cooperation, competitive pressure, environmental uncertainty, and business agility. Furthermore, we examine inter-organizational trust as a moderating effect between environmental characteristics and cloud computing assimilation. Data from a sample of 219 firms show the significant impacts of proposed variables with exception of technology infrastructure and technology compatibility. The findings also show that inter-organizational trust has a significant moderating effect in all paths except the one between business agility and cloud computing assimilation. The implication of this study suggests a theoretical framework explaining cloud computing assimilation and performance within inter-organizational environment.

Recently, many companies are interested in adopting cloud computing as their IT strategy. However, no distinct results have appeared in the substantial implementation of this technology. The main reason for such result is from the absence of research models leading to high impact studies on cloud computing. Thus, this study attempts to find a possible answer for the following research question : what factors influence an organizational assimilation of cloud computing? This study investigates Technology-Push (TP)/Need-Pull (NP) theory as a main factor affecting cloud computing assimilation. Also, the study examines the moderating role of organizational readiness. TP includes of perceived benefits, vendor pressure, cost savings, and IT activity intensity while NP includes competitor orientation, information technology policy, technological turbulence, and performance gaps. In addition, organizational readiness suggests two variables, financial resources and technological knowledge. Result from 217 adopting organizations showed that all of these factors with exception of competitor orientation and vendor pressure, have statistically significant impact on assimilation of cloud computing. The implications of the findings propose a theoretical framework for the foundation of studies on cloud computing assimilation, which can server as important practical guidelines for technology development.

In this study, a three-dimensional variational(3DVAR) data assimilation system was developed for the operational numerical weather prediction(NWP) system at the Republic of Korea Air Force Weather Group. The Air Force NWP system utilizes the Weather Research and Forecasting(WRF) meso-scale regional model to provide weather information for the military service. Thus, the data assimilation system was developed based on the WRF model. Experiments were conducted to identify the nested model domain to assimilate observations and the period appropriate in estimating the background error covariance(BEC) in 3DVAR. The assimilation of observations in domain 2 is beneficial to improve 24-h forecasts in domain 3. The 24-h forecast performance does not change much depending on the estimation period of the BEC in 3DVAR. The results of this study provide a basis to establish the operational data assimilation system for the Republic of Korea Air Force Weather Group.

This study examined that the assimilated web technologies can contribute to IS(information system) success. Through hierarchical regression analysis, the following findings are identified. First, top management championship, strategic investment rationale, and computer use and access affected web technology assimilation, and then web technology assimilation influenced on IS development success positively. Second, top management championship had more influence than other independent variables in strategies dimension of web technologies assimilation while strategic investment rationale did in activities dimension. Third, the strategies assimilation was more dominant than the activities assimilation for IS success. Thus it is concluded that IT including web technologies brings organizations a powerful business tool and high profit.

The multifarious array of benefits to the e-Government systems research, from evaluative frameworks and conceptual models to guidelines for initiatives, adoption, and assimilation, evidences the requirement, both from the researcher's and the practitioner's standpoint, of sound theoretical foundations that can be applied directly in practice. Grounded upon structuration theory, this paper proposes a framework for e-Government systems assimilation through the structuration of its organizational factors. Upon this proposition, we map the factors of e-Government systems assimilation with the organizational meta-structures of signification, domination and legitimization. The framework is then tested for the case of one particular e-Government systems of Korean government. The juxtaposition of the theoretical position and the practical findings leads us to isolate the organizational, technological, and inter-organizational factors that shape the meta-structures for the assimilation of e-Government systems. This framework offers interesting possibilities to researchers in exploring the relationships and insights into the complex interactions that shape the relationships among government, people and technology. Thus, the paper's contribution lies on three axes: first, the furthering of a theoretical perspective of e-Government systems assimilation; second, a detailed exposition of the structuration theory and an illustration of its application to the issues of e-Government systems assimilation in the organizational context; and finally, developed framework through the isolation of a usable set of theoretically grounded factors affecting e-Government systems assimilation that can be applied in future research and practice.

This paper presents the applications of spatial interpolation and assimilation methods for satellite and ground meteorological data, including temperature, relative humidity, and precipitation in regions of Vietnam. In this work, Universal Kriging is used for spatially interpolating ground data and its interpolated results are assimilated with corresponding satellite data to anticipate better gridded data. The input meteorological data was collected from 98 ground weather stations located all over Vietnam; whereas, the satellite data consists of the MODIS Atmospheric Profiles product (MOD07), the ASTER Global Digital Elevation Map (ASTER DEM), and the Tropical Rainfall Measuring Mission (TRMM) in six years. The outputs are gridded fields of temperature, relative humidity, and precipitation. The empirical results were evaluated by using the Root mean square error (RMSE) and the mean percent error (MPE), which illustrate that Universal Kriging interpolation obtains higher accuracy than other forms of Kriging; whereas, the assimilation for precipitation gradually reduces RMSE and significantly MPE. It also reveals that the accuracy of temperature and humidity when employing assimilation that is not significantly improved because of low MODIS retrieval due to cloud contamination.

Many organizations have introduced information technology (IT) as an innovation to gain competitive advantages as business environments have become increasingly complex and rapidly changing. Despite the large investment of IT, there have been mixed results about whether IT creates business values. Considering that IT assimilation may play an important role in explaining IT productivity paradox, this study examines the formation of IT assimilation and its effect on the organizational performance. To do so, this study suggests a research model based on Innovation Diffusion Theory by incorporating organization system, communication channel, change acceptability, and innovation factors, and then attempts to empirically explore the role of IT assimilation for enhanced organizational performance using data collected at the organizational level. Structural equation analysis using AMOS provides significant support for part of proposed relationships. Specifically, we have found encouraging results on the role of IT assimilation by identifying its mediating effect on the organizational performance. Theoretical and practical implications of the findings are discussed accordingly.
