    An espoused cultural perspective to understand continued intention to use mobile applications: a four-country study of mobile social media application usability
    Hoehle, Hartmut; Zhang, Xiaojun; Venkatesh, Viswanath (Taylor & Francis, 2015-05-01)
    As most mobile applications are tailored for worldwide consumption, it is a significant challenge to develop applications that satisfy individuals with various cultural backgrounds. To address this issue, we drew on a recently developed conceptualization and associated instrument of mobile application usability to develop a model examining the impact of mobile social media application usability on continued intention to use. Drawing on Hofstede's five cultural values, we incorporated espoused cultural values of masculinity/femininity, individualism/collectivism, power distance, uncertainty avoidance, and long-term orientation into our model as moderators. To test the model, we collected data from 1,844 consumers in four countries - the U.S., Germany, China, and India - who use mobile social media applications on their smartphones. The results provided support for the role of espoused national cultural values in moderating the impact of mobile social media application usability on continued intention to use and the model, with espoused cultural values explaining significantly more variance in continued intention to use (i.e., 38%) than the main effects-only model (i.e., 19%). Interestingly, our results demonstrated that culture at the national level did not play a significant role in affecting the relationship between usability constructs and continued intention to use, thus underscoring the importance of espoused culture.

    From Design Principles to Impacts: A Theoretical Framework and Research Agenda
    Zhang, Xiaojun; Venkatesh, Viswanath (2018)
    This paper integrates three streams of research in information systems─i.e., IS success, technology adoption, and human-centered design principles─to extend our understanding of technology use. A theoretical framework that incorporates the core ideas from these three streams of research, along with task, is presented. We leverage the proposed framework to present propositions that could guide future work. Specifically, the propositions developed relate system design principles to use and net benefits (i.e., job performance and job satisfaction) and rich use to job performance. We further suggest several broad potential future research directions.

    ICT for Development in Rural India: A Longitudinal Study of Women's Health Outcomes
    Venkatesh, Viswanath; Sykes, Tracy Ann; Zhang, Xiaojun (Society for Information Management, 2020-06-01)
    With a view toward improving the success of information and communication technology (ICT) initiatives in less developed countries in general and India in particular, this work seeks to uncover reasons for success and failure of ICT for development (ICT4D) initiatives. We drew on social networks theory in general and social contagion theory in particular, and examined the impact of advice network constructs on ICT kiosk use and the impact of ICT kiosk use on women's health outcomes (i.e., seeking modern medical care and maternal mortality). A two-level model (i.e., village and individual) was developed to understand how women in rural India were influenced by other women in their advice networks to use ICT kiosks, and the effects of ICT kiosk use on seeking modern medical care and maternal mortality. At the village level, we proposed lead user network effects. At the individual level, we proposed structural network effects of other women in a focal woman's network on individual outcomes of ICT kiosk use, seeking modern medical care, and maternal mortality. We focused on network position (i.e., centrality) and network tie strength (i.e., strong ties and weak ties) as explanatory variables. Specifically, we argued that strong tie centrality will have an adverse effect on ICT kiosk use, whereas weak tie centrality will have a favorable effect. We also argued ICT kiosk use will have a positive effect on seeking modern medical care and a negative effect on maternal mortality. Finally, we argued that seeking modern medical care will have a negative effect on maternal mortality. Our model was mostly supported in data collected about 6,710 women in 10 intervention group villages in rural India and 8,344 women in the control group villages over a period of approximately 7 years.

(PLOS, 2010-09-01)
    A synergistic combination of two next-generation sequencing platforms with a detailed comparative BAC physical contig map provided a cost-effective assembly of the genome sequence of the domestic turkey (Meleagris gallopavo). Heterozygosity of the sequenced source genome allowed discovery of more than 600,000 high quality single nucleotide variants. Despite this heterozygosity, the current genome assembly (,1.1 Gb) includes 917 Mb of sequence assigned to specific turkey chromosomes. Annotation identified nearly 16,000 genes, with 15,093 recognized as protein coding and 611 as non-coding RNA genes. Comparative analysis of the turkey, chicken, and zebra finch genomes, and comparing avian to mammalian species, supports the characteristic stability of avian genomes and identifies genes unique to the avian lineage. Clear differences are seen in number and variety of genes of the avian immune system where expansions and novel genes are less frequent than examples of gene loss. The turkey genome sequence provides resources to further understand the evolution of vertebrate genomes and genetic variation underlying economically important quantitative traits in poultry. This integrated approach may be a model for providing both gene and chromosome level assemblies of other species with agricultural, ecological, and evolutionary interest.

    A Risk Mitigation Framework for Information Technology Projects: A Cultural Contingency Perspective
    Maruping, Likoebe M.; Venkatesh, Viswanath; Thong, James YL L.; Zhang, Xiaojun (Routledge, 2019-01-02)
    As new information technology (IT) platforms continue to emerge, the technical project risk associated with developing IT projects for these platforms is particularly challenging for organizations. We develop a nomological network of people, process, and technology to gain insight into how the effect of technical project risk can be mitigated at the IT project team level. Drawing on cultural contingency theory, the IT project risk framework, and the IT project management literature, we elaborate on the IT project team composition and team processes necessary to mitigate technical project risk. We tested the nomological network by conducting a field study of 325 IT project teams over a 3-year period at a large corporation in China. We found that project risk mitigation processes mediated the effect of IT project teams’ cultural composition on IT project performance, and the effect of these processes on IT project performance was stronger under high levels of technical project risk compared to low levels of such risk. By incorporating the cultural contingency theory into developing a nomological network of technical risk mitigation processes, this work not only contributes to the IT project management literature, but also provides suggestions for practitioners on how to better leverage people, process, and technology in mitigating IT project risks.
