Understanding Impulsive Buying Behavior in Mobile Commerce

Mobile commerce, under the mature development of mobile devices and mobile technology services, has gradually influenced consumer shopping behavior and e-commerce patterns. The majority of past research of mobile commerce has concentrated on mobile technology and consumer shopping behavior. Fewer works took a mobile media application point of view to discuss the effects of mobile devices, mobile service performance and content on consumers\u27 impulse buying intent. Therefore, the aim of this study is to take the perspective of mobile media technology convergence on combination with the impulsive personality of consumers and flow experience to understand the impulsive purchase intent of consumers on mobile commerce platforms. Data collected from 322 customers of the iTunes (App store) provide strong support for the research model. The results indicate that a higher level of impulsivity reduces the effect of enjoyment on irresistible urge to buy. The data also show that emotional conflict, positive buying emotion, mood management, cognitive deliberation, disregard the future and unplanned buying are important to impulsivity formation and thus relevant within the context of impulse buying intention. The survey results provide service providers to design applications that attract consumers to make impulse purchases

[Al(H2O)6][Cr(OH)6Mo6O18]·10H2O

The title compound, [Al(H2O)6][Cr(OH)6Mo6O18]·10H2O, hexa­aqua­aluminium hexa­hydroxidoocta­deca­oxido­molybdo­chromate(III) deca­hydrate, crystallizes isotypically with its gallium analogue [Ga(H2O)6][Cr(OH)6Mo6O18].10H2O. In the structure of the title compound, both the [Al(H2O)6]3+ cation and the Anderson-type [Cr(OH)6Mo6O18]3− anion lie on centres of inversion. The anion is composed of seven edge-sharing octa­hedra, six of which are MoO6 octa­hedra that are arranged hexa­gonally around the central Cr(OH)6 octa­hedron. The anions are linked to each other by O—H⋯O hydrogen bonds into infinite chains along [100]. These chains are further connected with the [Al(H2O)6]3+ cations through O—H⋯O hydrogen bonds into sheets parallel to (01). O—H⋯O hydrogen bonds involving all the lattice water mol­ecules finally link the sheets into a three-dimensional network

Collapsing domain walls beyond Z2Z_2

Discrete symmetries are widely imposed in particle theories. It is well-known that the spontaneous breaking of discrete symmetries leads to domain walls. Current studies of domain walls have focused on those from the spontaneous breaking of a $Z_2$ symmetry. Larger discrete symmetries have multiple degenerate vacua, leading to the domain walls in principle different from the simplest $Z_2$ domain wall. We take domain walls from $Z_N$ symmetry breaking as an illustrative study, and study in detail the $Z_3$ case, in which semi-analytical results for the tension and thickness of domain walls are derived. Explicit symmetry breaking terms lead to the dynamics of domain walls collapsing more complicated than the $Z_2$ case. Gravitational wave signals deviate from those from $Z_2$ domain walls.Comment: 9 pages, 4 figure

Prognostic value of routine laboratory variables in prediction of breast cancer recurrence.

The prognostic value of routine laboratory variables in breast cancer has been largely overlooked. Based on laboratory tests commonly performed in clinical practice, we aimed to develop a new model to predict disease free survival (DFS) after surgical removal of primary breast cancer. In a cohort of 1,596 breast cancer patients, we analyzed the associations of 33 laboratory variables with patient DFS. Based on 3 significant laboratory variables (hemoglobin, alkaline phosphatase, and international normalized ratio), together with important demographic and clinical variables, we developed a prognostic model, achieving the area under the curve of 0.79. We categorized patients into 3 risk groups according to the prognostic index developed from the final model. Compared with the patients in the low-risk group, those in the medium- and high-risk group had a significantly increased risk of recurrence with a hazard ratio (HR) of 1.75 (95% confidence interval [CI] 1.30-2.38) and 4.66 (95% CI 3.54-6.14), respectively. The results from the training set were validated in the testing set. Overall, our prognostic model incorporating readily available routine laboratory tests is powerful in identifying breast cancer patients who are at high risk of recurrence. Further study is warranted to validate its clinical application

2-[(2,6-Diethyl­phen­yl)imino­meth­yl]-N-(2-methoxy­phen­yl)aniline

The title anilide–imine compound, C24H26N2O, features an intra­molecular N—H⋯N hydrogen bond involving the imine and anilide groups to generate an S(6) ring motif. The mol­ecule displays an E configuration about the imine C=N double bond, with the dihedral angle between the two benzene rings being 86.5°. The packing is stabilized by three different C—H⋯π inter­actions

Beyond Gisin's Theorem and its Applications: Violation of Local Realism by Two-Party Einstein-Podolsky-Rosen Steering

We demonstrate here that for a given mixed multi-qubit state if there are at least two observers for whom mutual Einstein-Podolsky-Rosen steering is possible, i.e. each observer is able to steer the other qubits into two different pure states by spontaneous collapses due to von Neumann type measurements on his/her qubit, then nonexistence of local realistic models is fully equivalent to quantum entanglement (this is not so without this condition). This result leads to an enhanced version of Gisin's theorem (originally: all pure entangled states violate local realism). Local realism is violated by all mixed states with the above steering property. The new class of states allows one e.g. to perform three party secret sharing with just pairs of entangled qubits, instead of three qubit entanglements (which are currently available with low fidelity). This significantly increases the feasibility of having high performance versions of such protocols. Finally, we discuss some possible applications.Comment: 9 pages, 1 figur

Demonstration of Einstein-Podolsky-Rosen Steering with Enhanced Subchannel Discrimination

Einstein-Podolsky-Rosen (EPR) steering describes a quantum nonlocal phenomenon in which one party can nonlocally affect the other's state through local measurements. It reveals an additional concept of quantum nonlocality, which stands between quantum entanglement and Bell nonlocality. Recently, a quantum information task named as subchannel discrimination (SD) provides a necessary and sufficient characterization of EPR steering. The success probability of SD using steerable states is higher than using any unsteerable states, even when they are entangled. However, the detailed construction of such subchannels and the experimental realization of the corresponding task are still technologically challenging. In this work, we designed a feasible collection of subchannels for a quantum channel and experimentally demonstrated the corresponding SD task where the probabilities of correct discrimination are clearly enhanced by exploiting steerable states. Our results provide a concrete example to operationally demonstrate EPR steering and shine a new light on the potential application of EPR steering.Comment: 16 pages, 8 figures, appendix include
