Extant research examines the factors that cause the initial adoption of digital technologies, like mobile wallets, with limited focus on post-adoption behaviours. This work proposes a novel extended expectation–confirmation model which explores the impact of pre-adoption expectancies and confirmation on post-adoption satisfaction and continuance intentions. The model also explores the roles played by the post-adoption factors like perceived user interface quality, perceived security and self-efficacy. The findings indicate that pre-adoption performance/effort expectancies impact consumption-driven confirmation, which in turn affects the post-adoption perceived usefulness, post-adoption perceived security, and user satisfaction. Further, satisfaction, post-adoption self-efficacy and post-adoption perceived usefulness are found to be strong antecedents of the user’s continuance intention. The framework contributes to the extant research by integrating both pre- and post-adoption constructs that determine post-adoption continuance intentions. The framework also guides the M-wallet application developers to enhance user satisfaction and continuance intentions by meeting their pre-adoption expectations through consumption-driven confirmation, in order to stay relevant in an extremely competitive m-payments business.
Background and Aims 314 internationally adopted children were seen between 01/01/2008 and 31/03/2012 at the Institute of Tropical Medicine in Antwerp (Belgium). We describe the prevalence of ...pathogenic intestinal parasites in this population. Methods Retrospective analysis of patient records. Feces samples were obtained in 307/314 children. In addition, serology for Strongyloides and Schistosoma was performed. Results Pathogenic parasites were found in 55.7% (53% in children 0–5 years, 72.1% > 5years). When counting any parasites, 65.9% of children were found positive (61.4% for 0–5 years, 93% for >5 years). 37.5% of children with positive samples had ≥ 3 parasites. Analysis by age in children from the 4 most represented countries (n=285) is shown in table.

Background and Aims Eosinophilia may be associated with parasitic infection. To our knowledge the predictive value of eosinophilia has not been determined in internationally adopted children (IAC). ...Methods Eosinophilia definition: absolute count ≥ 450/µl. Eosinophil counts were available in 285/314 IAC seen between 01/01/2008 and 31/03/20012. Feces and serological examinations for Strongyloides and Schistosoma were done in all children. We calculated the positive predictive value, negative predictive value and likelihood ratios of eosinophilia ≥ 450/µl for all parasites, solely pathogenic and solely tissue invading parasites in all 285 and 197 Ethiopian children. Results Abstract 930 Table 1All 285 children Any parasites No parasites Pathogenic parasites No pathogenic parasites Tissue invading parasites No tissue invading parasites Eosinophils ≥ 450 65 13 60 18 37 41 Eosinophils < 450 129 78 99 108 40 167 PPV 83% 77% 47% NPV 38% 52% 81% LR+ 2.35 2.64 2.44 LR- 0.78 0.73 0.65 Abstract 930 Table 2197 Ethiopian children Any parasites No parasites Pathogenic parasites No pathogenic parasites Tissue invading parasites No tissue invading parasites Eosinophils ≥ 450 59 9 54 14 33 35 Eosinophils < 450 92 37 72 57 30 99 PPV 87% 79% 49% NPV 29% 44% 77% LR+ 2 2.17 2.01 LR- 0.76 0.71 0.64 Conclusion In this population the predictive value of eosinophilia is weak for parasitic infection.
Chinese adoption is often viewed as creating new possibilities for the formation of multicultural, cosmopolitan families. For white adoptive families, it is an opportunity to learn more about China ...and Chinese culture, as many adoptive families today try to honor what they view as their children's "birth culture." However, transnational, transracial adoption also presents challenges to families who are trying to impart in their children cultural and racial identities that they themselves do not possess, while at the same time incorporating their own racial, ethnic, and religious identities. Many of their ideas are based on assumptions about how authentic Chinese and Chinese Americans practice Chinese culture.
Based on a comparative ethnographic study of white and Asian American adoptive parents over an eight year period,How Chinese Are You?explores how white adoptive parents, adoption professionals, Chinese American adoptive parents, and teens adopted from China as children negotiate meanings of Chinese identity in the context of race, culture, and family. Viewing Chineseness as something produced, rather than inherited, Andrea Louie examines how the idea of "ethnic options" differs for Asian American versus white adoptive parents as they produce Chinese adoptee identities, while re-working their own ethnic, racial, and parental identities. Considering the broader context of Asian American cultural production, Louie analyzes how both white and Asian American adoptive parents engage in changing understandings of and relationships with "Chineseness" as a form of ethnic identity, racial identity, or cultural capital over the life course. Louie also demonstrates how constructions of Chinese culture and racial identity dynamically play out between parents and their children, and for Chinese adoptee teenagers themselves as they "come of age."How Chinese Are You?is an engaging and original study of the fluidity of race, ethnicity, and cultural identity in modern America.
Family-making in America is in a state of flux—the ways people compose their families is changing, including those who choose to adopt. Broken Links, Enduring Ties is a groundbreaking comparative ...investigation of transnational and interracial adoptions in America. Linda Seligmann uncovers the impact of these adoptions over the last twenty years on the ideologies and cultural assumptions that Americans hold about families and how they are constituted. Seligmann explores whether or not new kinds of families and communities are emerging as a result of these adoptions, providing a compelling narrative on how adoptive families thrive and struggle to create lasting ties. Seligmann observed and interviewed numerous adoptive parents and children, non-adoptive families, religious figures, teachers and administrators, and adoption brokers. The book uncovers that adoption—once wholly stigmatized—is now often embraced either as a romanticized mission of rescue or, conversely, as simply one among multiple ways to make a family.
"Chosen Children" examines the role of the adoption marketplace in shaping how transracial adoptive families are sorted and matched, and analyzes what these practices suggest about race in the United ...States. In contrast to previous work on race and adoption markets that focus on the experiences of adoptive parents, Raleigh's project focuses on adoption workers--social workers, attorneys, and counselors. Taking a market approach that treats adoptive parents as consumers and children as commodities, Raleigh brings together interviews with adoption practitioners, participant observation at adoption information sessions, and adoption statistics in order to demonstrate how the downturn in supply of "adoptable honorary white children" (which she defines as Asian and hispanic children) led to the increased popularity of the transracial adoption of foreign-born and biracial black children.
Analyzes transnational and transracial adoption, highlighting the past and continuing discourses around adoption as it relates to race, nation, immigration, belonging, and citizenship.
This paper studies government subsidies for green technology adoption while considering the manufacturing industry’s response. Government subsidies offered directly to consumers impact the supplier’s ...production and pricing decisions. Our analysis expands the current understanding of the price-setting newsvendor model, incorporating the external influence from the government, who is now an additional player in the system. We quantify how demand uncertainty impacts the various players (government, industry, and consumers) when designing policies. We further show that, for convex demand functions, an increase in demand uncertainty leads to higher production quantities and lower prices, resulting in lower profits for the supplier. With this in mind, one could expect consumer surplus to increase with uncertainty. In fact, we show that this is not always the case and that the uncertainty impact on consumer surplus depends on the trade-off between lower prices and the possibility of underserving customers with high valuations. We also show that when policy makers such as governments ignore demand uncertainty when designing consumer subsidies, they can significantly miss the desired adoption target level. From a coordination perspective, we demonstrate that the decentralized decisions are also optimal for a central planner managing jointly the supplier and the government. As a result, subsidies provide a coordination mechanism.

Objectives: This literature review identifies and categorises, from an organisational management perspective, barriers to the use of HIT or ICT for health. Based on the review, it offers policy ...interventions. Methods: This systematic literature review was carried out during December 2009 and January 2010. Additional on-going reviews of updates through automated system alerts took place up until this paper was submitted. A total of thirty-one sources were searched including nine software platforms/databases, fifteen specialised websites/targeted databases, Google Scholar, ISI Science Citation Index and five journals hand-searched. Results: The study covers seventy-nine articles on organisational barriers to ICT adoption by healthcare professionals. These are categorised under five main headings - (I) Structure of healthcare organisations; (II) Tasks; (III) People policies; (IV) Incentives; and (V) Information and decision processes. A total of ten subcategories are also identified. By adopting an organisational management approach, some recommendations to remove organisational management barriers are made. Conclusions: Despite their apparent promise, health information technologies (HIT) have proved difficult to implement. This systematic review reveals the implementation barriers associated to organisational management and their interrelations. Several important future directions in the field are also suggested: (1) there is a need for further research providing evidence of HIT cost-effectiveness as well as the development of optimal HIT applications; (2) more information is needed regarding organisational change, incentives, liability issues, end-users HIT competences and skills, structure and work process issues involved in realising the benefits from HIT. Future policy interventions should consider the five dimensions identified when addressing the impact of HIT in healthcare organisational systems, and how the impact of an intervention aimed at a particular dimension would interrelate with others.
