Are we going to go to Mars or not ? Now would be a good time to decide. Are you listening, President Obama? Yes, the president has lots of things on his mind. But that?s true of any president, anytime. And the fact is, the U.S. government is already spending billions of dollars a year on a space program that has a trip to Mars as its ultimate but inadequately funded and too-far-off-to-get-excited-about goal. 相似文献

The objectives of this study are to investigate (1) the positive effects of smartphone users’ core self-evaluations (CSEs), online consumer conformity, and the social identity of their emotions, (2) the effects of their positive emotions on their trust, and (3) the effects of their trust on their intention to purchase paid apps and willingly engage in co-production. A questionnaire was employed to examine the relationship between the users’ CSEs, online consumer conformity, and social identity, on the one hand, with their intention to purchase paid apps and willingly engage in co-production on the other hand. The findings were as follows: (1) CSE, online consumer conformity, and social identity positively affected the users’ emotions, (2) positive emotions had a significantly positive effect on user trust, and (3) trust had significantly positive effects on the users’ intention to purchase paid apps. 相似文献

Imagine that you could make hydrogen atoms do something that quantum mechanics says they can?t: slip into an energy state below the ground state, the collapse releasing 100 times as much energy as you?d get by just burning the hydrogen. If you could harness the heat to produce power, using hydrogen from water as fuel, you?d consume no oil, create no fumes, and solve the problems of energy and global warming forever. 相似文献

In this paper, we study optimal nonlinear pricing policy design for a monopolistic network service provider in the face of a large population of users of different types described by a given probability distribution. In an earlier work (Shen and Ba?ar in IEEE J. Sel. Areas Commun. 25(6):1216?C1223, 2007), we had considered games with symmetric information, in the sense that either users?? true types are public information available to all parties, or each user??s true type is private information known only to that user. In this paper, we study the intermediate case with information asymmetry; that is, users?? true types are shared information among the users themselves, but are not disclosed to the service provider. The problem can be formulated as an incentive-design problem, for which an ??-team optimal incentive (pricing) policy has been obtained, which almost achieves Pareto optimality for the service provider. A comparative study between games with information symmetry and asymmetry are conducted as well to evaluate the service provider??s game preferences. 相似文献

Why do firms adopt cloud computing? A comparative analysis based on South and North Europe firm data
In this paper we empirically investigate and compare to what extent Northern and Southern European firms view cloud computing (CC) as a means of: (a) ICT investment reduction; (b) supporting and facilitating product/service innovation and process innovation; (c) experimenting with and exploiting new ICT; and (d) supporting and facilitating electronic innovation collaboration. This is done by estimating econometrically a model of CC adoption propensity containing measures of the four main adoption motives mentioned above besides further variables that are associated with technology adoption and a series of controls for firm size, sector and country affiliation. Our study is based on a dataset collected through the e-Business W@tch Survey of the European Commission from 556 European firms from the glass, ceramic and cement sectors. These findings indicate that Southern European firms are mainly oriented towards ‘first-level’ cost (and especially investment) reduction related benefits from CC as well as from new emerging ICT, while on the contrary Northern European firms are mainly oriented towards ‘second-level’ transformation related benefits from CC, which are associated with support and facilitation of innovation and external collaboration. 相似文献

Few literature studies have investigated the relationships between different uses and gratifications (U&Gs) of mobile instant messaging (MIM) apps, continuation, and purchase intentions. To address this gap, the researchers aimed to examine the influence of the content, social, process, and technology U&Gs of MIM on continuation intentions toward MIMs, and purchase intentions toward virtual goods available on MIMs. A comprehensive research model was developed based on the U&G theory, which was tested using cross-sectional data from 309 Japanese MIM users. The study considered six different U&Gs of MIM as independent variables and purchase intentions towards stickers and continuation intentions towards MIM as dependent variables. The study results suggest that exposure U&G has a significant positive association with MIM sticker purchase intentions. The entertainment and affection U&G are positively associated with continuation intentions towards MIM use. The study contributes to the literature by investigating U&Gs that motivate MIM users to have both positive purchase intentions toward virtual goods, such as stickers, and continuation intentions toward MIMs. The study has significant theoretical and practical implications for both researchers and practitioners who are interested in virtual goods, the virtual economy, MIM apps, social media, new media, and the service economy. 相似文献

Mobile telephony and its services have demonstrated direct impact on economic growth and social development. Offering users opportunities to keep pace with the rapid shifts in the mobile technology paradigm—from 1G to 2G, 3G, 4G, and now 5G—has also enabled businesses to earn appropriate returns on their investment. Existing literature has considered macro (policies) and micro factors (end-user level) in isolation to study diffusion, especially in the early phases of technology evolution. This study presents a framework which is a novel attempt to jointly evaluate the influence of macro and micro factors (i.e., governmental policies, and other market and user dynamics) on the diffusion of mobile telephony and its services in India. Developments in the Indian telecommunication sector (1997–2013) are used to develop the framework, and the recent developments (from latter half of year 2013–2018) are then used to validate the framework. The framework offers interesting insights on what drives Indian mobile service market showing interactions between the two sets of factors through a cause effect loop. 相似文献

Smart sensor network arises as a new generation of sensor networks, where a crowd of possibly anonymous volunteers are involved in the tasks of collecting data from the surrounding environment and providing it to the community. In this paper, we analyze one of the main questions, often forgotten, in these scenarios: whether or not we can trust the sensor readings provided by the individuals engaged in the sensor network. We introduce a data reliability architecture capable of filtering and validating sensor readings in an open environment, where not all users are equally honest. Simulations based on a real world smart sensor application allow us to make a first analysis of the proposed architecture's performance and the variables that have a significant impact on this performance.

Using self-reported survey data (N = 281), the present study explores the structural relationships among mobile users’ perceptions of the suitability of two types of mobile news (political feature news and entertainment news), users’ motivations for mobile news usage, and their behavioral patterns. Our findings show that two types of perceived suitability for mobile news, particularly for political feature news, are strongly associated with all dimensions of motivations for mobile news usage. Furthermore, as predicted, our findings show that the information-seeking motive is the very factor that determines mobile news usage. The results also reveal that the accessibility motive mediates the relationship between the perceived suitability of obtaining news via a mobile device and users’ mobile news behavior. However, contrary to our expectation, the social utility motive does not mediate the relationship between users’ perceptions of the suitability of mobile devices for this purpose and their mobile news usage. Finally, the information-seeking and accessibility motives each have an indirect effect on the association between perceived suitability and mobile news usage. The implications of the study and recommendations for future research are also discussed. 相似文献

Drawing from evolutionary psychology of anthropomorphism and social phobia, two between-subjects experiments examined the effects of different types of customer service chatbots. Experiment 1 supports the interaction effects between chatbots’ anthropomorphism and consumers’ social phobia on continuance use intention and willingness to recommend the chatbot. Consumers with high social phobia prefer anthropomorphic chatbots to less anthropomorphic chatbots. Experiment 2 confirms the moderating role of social phobia in determining the effects of consumer-chatbot personality matching (similarity attraction) vs. mismatching (complementarity attraction) on the outcome variables only for competent chatbots. For the consumer-chatbot personality mismatching condition, developing competent chatbots for less conscientious consumers with high social phobia will help alleviate socially isolated consumers’ social pain, while developing too smart chatbots for less conscientious consumers with low social phobia can have detrimental effects. Evolutionary psychological mechanisms and managerial implications for chatbot developers and creative directors are explained. 相似文献
