As mouse-driven desktop computers give way to touchpad laptops and touchscreen tablets, the role of touch in online consumer behavior has become increasingly important. This work presents initial ...explorations into the effects of varying touch-based interfaces on consumers, and argues that research into the interfaces used to access content can be as important as research into the content itself. Two laboratory studies using a variety of touch technologies explore how touchscreen interfaces can increase perceived psychological ownership, and this in turn magnifies the endowment effect. Touch interfaces also interact with importance of product haptics and actual interface ownership in their effects on perceived product ownership, with stronger effects for products high in haptic importance and interfaces that are owned. Results highlight that perceptions of online products and marketing activities are filtered through the lens of the interfaces used to explore them, and touch-based devices like tablets can lead to higher product valuations when compared to traditional computers.
This study investigated ownership and on-campus use of laptops, tablets, and smartphones, using survey information on Dutch university students. We show that 96% of students own at least one of these ...mobile IT devices (i.e., a laptop, tablet, or smartphone). Using econometric modelling, we also show that student income, parental income, gender, immigrant parents, and household type (e.g., living with parents) have a statistically significant but small effect on mobile IT device ownership. The demand for tablets is relatively income inelastic, and the demand for laptops and smartphones extremely so. Therefore ownership rates are high for all student groups, including lower income students. However, students leave their laptops (and tablets) at home most of the time, mainly because they find it cumbersome to carry a laptop, and the vast majority of students hold the opinion that abolishing computer labs while facilitating laptop use is a bad idea, despite the didactical advantages this may have during lectures. Thus, it appears that the current high ownership rates of mobile IT devices by no means imply students' preference or support for university Bring Your Own Device (BYOD) strategies.

This work discusses the implementation, capabilities, and validation of Shift, a massively parallel Monte Carlo radiation transport package authored at Oak Ridge National Laboratory. Shift has been ...developed to scale well from laptops to small computing clusters to advanced supercomputers and includes features such as support for multiple geometry and physics engines, hybrid capabilities for variance reduction methods such as the Consistent Adjoint-Driven Importance Sampling methodology, advanced parallel decompositions, and tally methods optimized for scalability on supercomputing architectures. The scaling studies presented in this paper demonstrate good weak and strong scaling behavior for the implemented algorithms. Shift has also been validated and verified against various reactor physics benchmarks, including the Consortium for Advanced Simulation of Light Water Reactors' Virtual Environment for Reactor Analysis criticality test suite and several Westinghouse AP1000® problems presented in this paper. These benchmark results compare well to those from other contemporary Monte Carlo codes such as MCNP5 and KENO.
A multi-resonant, electromagnetic-compatible (EMC), hybrid laser- direct-structuring (LDS) antenna capable of operating in the 2.4, 5, and new 6 GHz wireless local area network (WLAN) bands is ...presented. The LDS metal patterns are formed on a holder with the volume of 8 mm × 10 mm × 30 mm and comprise an inner loop, a parasitic strip, and three-sided, vertical ground walls. The fundamental and the first higher-order resonance of the parasitic strip acting as a shorted monopole generate the 2460 and 6460 MHz modes. In addition, two loop modes formed by the inner loop with the parasitic strip and the inner loop only, respectively, contribute to the 5420 and 7020 MHz resonance. All of these together generate a tri-WLAN-band, 2.4/5/6 GHz operation. The vertical ground also functions as the shielding walls that assorted conductive components can be placed in the close vicinity of the design for compact integration. The proposed antenna applied to laptop computers for the most recent Wi-Fi 6E operation is demonstrated in this article.
A monopole exciter antenna installed in the hinge slot region of a slim laptop with metal covers is presented. The exciter antenna comprises a feeding strip and a matching strip that form a ...two-branched monopole structure. A small antenna size of 35 × 8 mm2 enables installation in the hinge slot region between the upper metal cover and the base metal cover of a slim laptop. The proposed exciter antenna can be integrated with the metal surroundings (metal covers and metal hinges) to enhance the operating bandwidth and thus cover the long-term evolution/wireless wide area network band with high radiation efficiency. The antenna efficiency is approximately 68–88% in the lower band and 52–78% in the upper band.
We present a precise and efficient computation of the two-loop amplitudes entering the Higgs boson pair production process via gluon fusion. Our approach is based on the small-Higgs-mass expansion ...while keeping the full dependence on the top quark mass and other kinematic invariants. We compare our results to the up-to-date predictions based on a combination of sector decomposition and high-energy expansion. We find that our method provides precision numeric predictions in the entire phase space, while at the same time is highly efficient as the computation can be easily performed on a normal desktop or laptop computer. Our method is valuable for practical phenomenological studies of the Higgs boson pair production process, and can also be applied to other similar processes.
The past decade has seen the expansion of personal digital technologies into schools. With many students and teachers now possessing smartphones, tablets, and laptops, schools are initiating ...one-to-one and 'Bring Your Own Device' (BYOD) policies aiming to make use of these 'personal devices' in classrooms. While often discussed in terms of possible educational benefits and/or organisational risks, the actual presence of personal devices in schools tends to be more mundane in nature and effect. Drawing upon ethnographic studies of three Australian high schools, this paper details ways in which the proliferation of digital devices has come to bear upon everyday experiences of school. In particular, the paper highlights the ways in which staff and students negotiate (in)appropriate technology engagement; the ordinary (rather than extraordinary) ways that students make use of their devices in classrooms; and the device-related tensions now beginning to arise in schools. Rather than constituting a radically 'transformational' form of schooling, the paper considers how the heightened presence of personal technologies is becoming subsumed into existing micro-politics of school organisation and control.
Several organizations have developed ongoing crowdsourcing communities that repeatedly collect ideas for new products and services from a large, dispersed "crowd" of nonexperts (consumers) over time. ...Despite its promises, little is known about the nature of an individual's ideation efforts in such an online community. Studying Dell's IdeaStorm community, serial ideators are found to be more likely than consumers with only one idea to generate an idea the organization finds valuable enough to implement, but they are unlikely to repeat their early success once their ideas are implemented. As ideators with past success attempt to again come up with ideas that will excite the organization, they instead end up proposing ideas similar to their ideas that were already implemented (i.e., they generate less diverse ideas). The negative effects of past success are somewhat mitigated for ideators with diverse commenting activity on others' ideas. These findings highlight some of the challenges in maintaining an ongoing supply of quality ideas from the crowd over time.

Multifunctional glass windows that combine energy storage and electrochromism have been obtained by facile thermal evaporation and electrodeposition methods. For example, WO3 films that had been ...deposited on fluorine‐doped tin oxide (FTO) glass exhibited a high specific capacitance of 639.8 F g−1. Their color changed from transparent to deep blue with an abrupt decrease in optical transmittance from 91.3 % to 15.1 % at a wavelength of 633 nm when a voltage of −0.6 V (vs. Ag/AgCl) was applied, demonstrating its excellent energy‐storage and electrochromism properties. As a second example, a polyaniline‐based pseudocapacitive glass was also developed, and its color can change from green to blue. A large‐scale pseudocapacitive WO3‐based glass window (15×15 cm2) was fabricated as a prototype. Such smart pseudocapacitive glass windows show great potential in functioning as electrochromic windows and concurrently powering electronic devices, such as mobile phones or laptops.
