Some of the approximately 400,000 children currently placed out-of-home in a public child welfare system will not reunify with their family of origin. They may instead be adopted into a new family. Adoption placements can be characterized by poor adjustment for children; some such placements even result in disruption or dissolution. We conducted a stratified Cox regression of 4,016 children from the Colorado public child welfare system. All of the children had a finalized adoption during the years 2002 through 2006. The two outcomes analyzed were new child protection and youth-in-conflict referrals and assessments for these previously adopted children. New child welfare referrals and assessments may be early indicators of poor adjustment for adopted children within the adoptive family. Study results indicate that older children and Hispanic children had higher rates of referral and assessment. Children with a pre-adoption history including longer time out-of-home or a larger number of out-of-home placements also experienced higher referral and assessment rates. Additional factors which predicted subsequent system re-involvement included presence of paid adoption assistance, adoption by a non-relative foster parent and younger adoptive parent age. Several study results were moderated by the presence or absence of an ethnic match between the child and the adoptive parents. We provide an overview of the statistical model used for analysis and we discuss implications of the study results for child welfare practice. 相似文献

This study is among the first attempts to empirically investigate the adoption of mobile government by rural populations in developing economies. Based on 409 validated questionnaires collected from families living in rural China, the study examines the interdependences among rural inhabitants' demographic attributes, their access to and perceptions of mobile government, and quantifies how their intention to use mobile government is influenced by technology attributes, social factors and trust beliefs. The results indicate that young males, who live far from a village center or market, and have some knowledge of recent government policies, tend to have a more positive perception of mobile government, and therefore become potential adopters of the service. Perceived ease of use, near-term usefulness, long-term usefulness, integrity, benevolence, image and social influence have significant and positive influences on the intention to use mobile government. Specifically, perceived ease of use, long-term usefulness and social influence have a direct influence on intention to use, while perceived near-term usefulness, integrity, benevolence and image have an indirect influence. 相似文献

The lack of success of information systems has been studied extensively. However, often only the implementation of an information system is studied without analysing the consequent effects on its adoption and later use. Our paper uses actor network theory to show how successful implementation and adoption can lead to a low level of later use and lack of achievement of the declarative goals. The same actors may form networks leading to a successful outcome in one particular situation but not in another. In such a way seamless implementation can hinder the subsequent use and hide problems from the management. An analysis of a case study of an information system's implementation, adoption and later use in a primary school allows a better understanding of the reasons for the subsequent low use. 相似文献

Purpose: This study examines the suitability of the system of rice intensification (SRI) for diverse small-scale farmers in Tanzania by exploring if poor and non-poor farmers adopt the system to a similar extent.
Originality: The suitability of low-external input technologies such as SRI for diverse African farmers is a contentious issue. Existing studies suggest that adoption may be skewed away from poorer farmers, but no studies have explicitly categorized farmers who participate in adoption of SRI.
Methods: Farmers exposed to SRI were randomly surveyed. Sample farmers were categorized into three socioeconomic groups – wealthier, middle-wealth, and poorer – using factor and cluster analysis approaches. Wealth category is then used in a logit model to determine probabilities of adopting SRI practices across the different groups.
Findings: The results indicate that middle-wealth group adopt SRI to a greater extent compared to the wealthier and poorer groups. The extent of adoption by wealthier and poorer groups is similar, although constraining circumstances differ. Access to factors that consistently explained adoption: contact with extension services, land with water, and labor, vary systematically among groups.
Theoretical implication: Low adoption is often assumed on reduced exposure to a technology, and non-adopters are expected to eventually adopt. The results suggest, however, that farmers, who have not adopted, may not do so, even after being exposed. SRI as a package does not fit their socioeconomic conditions.
Practical implications: To support adoption across all wealth categories, extension should focus on promoting individual practices rather than the package to enable farmers adopt practices that fit their socioeconomic characteristics. 相似文献

The nature of lead users and measurement of leading edge status 总被引：1，自引：1，他引：1
“Lead users” are defined as being at the leading edge of markets, and as having a high incentive to innovate. Empirical research has shown the value of lead user need and solution data to new product development processes. However, the nature of the lead user construct itself has not been studied to date. In this paper we fill this significant gap by proposing and evaluating a continuous analog to the lead user construct, which we call leading edge status (LES). We establish the validity and reliability of LES and examine the characteristics of users having high levels of this variable. We also offer a first exploration of how LES is related to traditional measures in diffusion theory such as dispositional innovativeness and time of adoption (TOA). We find a strong relationship and explain how users with high LES can offer a contribution to both predicting and accelerating early product adoption. 相似文献

Low uptake is one of the largest risks facing government agencies that seek to increase efficiency and reduce costs by providing services online. To date, very few studies have tested interventions to increase citizens' use of e-government services. Instead, almost all existing research has focused on identifying correlates of adoption. In the current study, we developed an intervention to increase citizens' use of an e-government service and tested it using a quasi-experiment. The intervention used several techniques informed by research from the applied behavioural sciences to encourage usage, including: altering defaults (customers who visited a customer service centre were invited to complete a form online rather than joining a queue), providing facilitating conditions (customer support was made available), and promoting the benefits and ease of the online service (a customer service representative and in-store written materials emphasised these points). Results indicated that the intervention significantly increased customers' use of the online service by 14.1 percentage points, 95% CI [9.1, 19.2]. Additionally, a survey of customers who experienced the intervention showed they were highly satisfied and appreciated the time-saving benefits, ease of use, and customer support provided. This study is among the first to provide a rigorous test of an intervention to encourage citizens to use e-government services, and can be used to inform practical efforts to increase e-government uptake. 相似文献

The economic development of rural India requires connecting remote villages to local and global supply chains. Yet, high rates of financial exclusion inhibit rural Indians from participating in these supply networks. We review the literature on financial inclusion, adoption, and blockchain in India, and posit that to resolve financial exclusion, the four challenges of geographical access, high cost, inappropriate banking products, and financial illiteracy need to be overcome. Next, we argue that blockchain technologies hold the potential to overcome most of these challenges. However, for blockchain technologies to become the cornerstone of financial inclusion initiatives, an understanding of technology adoption in India is needed. To guide the development of such understanding, we develop a research agenda on the antecedents of adoption, adoption patterns, and outcomes of adoption. Answering these research questions will lead to a nuanced understanding of adoption of blockchain-based technologies in rural India. The practical contribution of this paper is the discussion of how blockchain can alleviate the issue of financial exclusion in rural India, thereby providing a basis for a solution that could connect rural Indians to global supply chain networks. The theoretical contribution lies in the identification of knowledge gaps that should be answered to achieve financial inclusion of rural Indians. 相似文献

Geographic information systems (GIS) have generated great interest in the field of disaster management and have stimulated rich discussions in the domain. This case study describes how we selected and adapted a GIS-enabled mobile application to be used by field workers in the aftermath of cyclone Gaja in Tamil Nadu in 2018. It also analyses how the app was used by field workers to ensure faster electricity restoration in the cyclone-hit site. The app helped decision-makers, middle managers/supervisors, and field workers achieve faster restoration and deliver a more efficient post-disaster emergency response. The findings of this study could serve as a guide for emergency restoration teams in similar disaster management scenarios in the future. 相似文献

e-Government adoption model based on theory of planned behavior: Empirical validation 总被引：1，自引：0，他引：1
The e-Government phenomenon has become more important with the ever increasing number of implementations worldwide. A model explaining the e-Government adoption and the related measurement instrument – a survey – had been developed and validated in this study. In a post Technology Acceptance Model (TAM) approach, theory of planned behavior (TPB) was extended to fit the requirements of e-Government context. The adoption of student loans service of the higher education student loans and accommodation association of Turkey (KYK) was investigated to obtain data for empirical validation. The instrument was administered to over four-hundred students and partial least squares path modeling was employed to analyze the data. The results indicate that the model was an improvement over TAM in terms of predictive power. The constructs trust, perceived behavioral control and attitudes successfully explained the intention to use an e-Government service. The findings presented in this study provide useful insights for researchers and policy makers when dealing with e-Government services. 相似文献
