The Impact of O2O on Store Operation Model and Consumption Behavior—A Case Study of POS APP

The O2O business model is not only a consumption model, but also a new operation model. In the new retail era, what use considerations, function considerations and use benefits will online store POS and traditional hardware POS bring to physical stores applying the O2O model? Therefore, this study takes online store POS and traditional hardware POS as the research scope to investigate the use motivation, perceived value and use satisfaction of POS App. For the purpose of this study, a questionnaire survey was used. A total of 400 copies of the questionnaire were distributed and 400 valid copies were recovered. The valid recovery rate of the questionnaire was 100.0%. SPSS software was used for data statistics and analysis. The results show that: (1) POS App's "use motivation" has a direct and significant impact on "perceived value"; (2) POS App's "use motivation" has a direct and significant impact on "use satisfaction"; (3) POS App's "perceived value" has a direct and significant impact on "use satisfaction". It is hoped that the conclusions and suggestions provided in this study can be used as marketing adjustment strategies for physical stores when they implement O2O, so that the application of strategies can be more accurate and meets the needs of target customers. Introduction In addition to providing the goods required by customers, physical stores must also provide different services according to their different requirements, and must also understand the needs of customers' working environment and wearing habits, so that customers can have meticulous services. From the perspective of customers, the process of using creativity to improve services must create new values of services, as well as double guarantees of brand and quality. However, for consumers, non-customer loyalty and one-time consumption account for 85% of the total consumption. How to create customer value, customer loyalty and repeat purchase rate are the issues to be discussed in this paper. The motivation of this study is to feel the growing trend in cloud technology, e-commerce, mobile commerce, local economy, e-wallet, and serial services, and to see many physical stores continue to invest in serial services, mobile payment and other cross-industry cooperation, coupled with the popularity of modern smart phones and tablets which has also created unlimited business opportunities for many websites and applications and brought unlimited possibilities to many industries and business. O2O (Offline to Online) is a newly emerging mobile business model in recent years. The main consumption pattern is that "consumers enjoy services or obtain goods in physical stores, but pay for them on the Internet". The main motivation of this paper is to discuss the use intention of O2O from the perspective of consumption value through the study on the application of O2O business model in physical stores. The purpose of this study is as follows:
Variable Resource Allocation Using Multidisciplinary Optimization: Initial Investigations for System of Systems

The concept of a “System of Systems” (SoS) describes a large system of multiple systems – each capable of independent operation – that have been brought together to provide capabilities beyond those of each individual constituent system. Formulating and solving an SoS design problem has become increasingly important, particularly in the aerospace and defense industries, as customers have begun to ask contractors for broad capabilities and solutions rather than for specific individual systems. Part of an SoS design problem is determining the appropriate mix of both existing and yet-to-be-designed systems. While determining an appropriate mix of existing systems falls into the category of resource allocation, including features of a yet-to-be-designed system makes the problem more complicated by requiring the allocation of a variable resource. In this paper, a simple problem using an airline wishing to investigate how a new, yet-to-be-designed aircraft will impact the fleet operating costs provides an example of this type of problem. The resulting statement is a Mixed-Integer, Non-Linear Programming (MINLP) problem. Approaches for MINLP are applied to the problem, and these methods do generate solutions but at generally high computational cost. Using a response surface approach to model the airline design portion of the problem finds good solutions at much lower computational cost. A decomposition approach analogous to those of multidisciplinary optimization is also applied to the problem, in which there is an “allocation domain” and an “aircraft design domain”, and this approach also generates solutions, but at a lower computational cost. The MDOmotivated decomposition approach appears to have promise for the allocation of variable resources challenge presented by many SoS design problems.
Relation of State- and Trait-Math Anxiety to Intelligence, Math Achievement and Learning Motivation

This study investigates math anxiety (MA) by comparing trait-components of MA with real-time assessments of situational anxiety responses (state-components) in children. The research to date on MA in children is somewhat disparate in regard to methodology, and firm conclusions regarding the relation of MA to intelligence, math achievement and learning motivation are not readily drawn. Typically, the measures used in the MA research have differed by operationalizing either trait-MA and/or state- (or statelike)-MA, but have failed to compare the implications of their respective assumptions and the significance of their findings. Trait-MA and state-MA, self-ratings of math skills, attitudes towards mathematics, math achievement, the social anxiety, test anxiety, learning motivation and intelligence of 1,179 students (48.1% girls) from grades 4 and 5, were assessed. The findings yield evidence of a pronounced state-trait discrepancy. A negative correlation between state-MA and math achievement was observed for all intelligence levels, even when controlling for test- and social-anxiety traits, while there was no negative relation between trait-MA and achievement. State-MA was associated with lower intelligence, lower self-ratings, more negative attitudes, higher performance avoidance and work avoidance goals. In contrast, trait-MA was slightly related to higher mastery approach goals. The failure to adequately differentiate between state- and trait-based research into MA appears to be one reason for key inconsistencies between research findings and warrants further investigations.
Preverbs in Russian: situation or viewpoint aspect?

The present paper has two goals: to present the complex data of verbal prefixation of Russian, and to assess the validity of the Situation Aspect-Viewpoint Aspect (Smith 1991) distinction for preverbs, in particular the thesis that all preverbs are telicity-markers (Borer 2005). First, arguments are introduced to show that all prefixed verbs are automatically perfective (pf), all are subject to lexical restrictions. A preliminary conclusion is that all preverbs are telicity markers, contra Filip (2005, 2008) for whom the preverb is pre-functional (lexical). This raises the question of the exact nature of telicity. In the literature (Dowty 1979, Krifka 1998), telicity is tested by means of in x time frame adverbials. A more relaxed version of telicity is proposed, following Borer (2005) & Lakorczyk (2010): it suffices for an event to be either non divisive or non homogeneous to be telic. The concept is akin to Paducheva & Pentus’ (2008) terminativity: the function of the preverb is to seal off the event. This accounts for the behavior of po-delimitative verbs. The data show that some assumptions are not correct: po-delim verbs are currently extending their functional scope in Russian and often act as pf partners to impf verbs, they do not necessarily indicate short duration, and are subject to lexical restrictions (Dickey 2006). Finally, the role of the preverb with respect to viewpoint aspect is assessed. The conclusion is that it is Situation Aspect that is grammaticized in Russian by means of the preverbs, and not viewpoint aspect, which is derived by means of correlations.
Ionospheric Footprints of Detached Magnetotail Interchange Heads

Pritchett and Coroniti (2011, https://doi.org/10.1029/2011GL047527, 2013, https://doi.org/10.1029/2012JA018143) have predicted that the kinetic ballooning/interchange instability (BICI) can provoke reconnection onsets that lead to detached azimuthally thin earthward intrusions (heads) of depleted plasma tubes when βeq⩽ 100. Such detached BICI heads would be seen as localized earthward‐propagating dipolarization fronts. Using Time History of Events and Macroscale Interactions during Substorms observations in the plasma sheet at XGSM≈−11RE and conjugate All‐Sky Imager and magnetometer networks observations on the ground, we show four examples when prominent dipolarization fronts with moderate earthward flows were observed amidst azimuthally drifting interchange heads and concurrently with the ionospheric current intensifications near Time History of Events and Macroscale Interactions during Substorms footprints and auroral bright spots originating from dimmer azimuthal beads/rays. These events support the idea that some of the BICI heads detach from the region with reversed radial gradient of BZ due to local reconnection. The detached BICI heads propagate earthward‐driving ionospheric pseudo‐breakups.
ICT-Integration in Higher Education and Student Behavioral Change: Observations at University of Arusha, Tanzania

ICT-Based education is a system of instruction that involves combination of computers and communication technologies. ICT Integration is important in combating digital divide, bringing about digital opportunity and paradigm shift from teacher centered to student centered learning, whereby the teacher passes the information quicker and in a more understandable manner. This study aimed at evaluating ICT-Based Education and Students Behavioral Change at University of Arusha, Tanzania. Questionnaire was the only means for data collection and Cronbach alfa of above . 887 was established to signify that questionnaire items were highly reliable. T-test, ANOVA and Pearson product correlation coefficient tested three null hypotheses by the help of SPSS. The study established that University of Arusha educators are competent in the use of PowerPoint, Excel, Microsoft Word, online search procedures and internet programs and believe that ICT integration propels student centered approaches and increases the rate of learning. Educators, however, indicated lack of skills in online marking and data management procedures and limited integration of ICT resources in teaching learning transaction. Finally, the study established a positive and strong relationship between competence and application of ICT in teaching-learning transaction. This implies that the higher the competence, the likelihood of educators to integrate ICT in teaching-learning transaction.

Contribution to the CCP-WSI Blind Test Series 3: Analysis of scaling effects of moored point-absorber wave energy converters in a CFD-based numerical wave tank

Computational fluid dynamics (CFD) based numerical wave tanks (NWTs) can provide valuable insight into the hydrodynamic performance of wave energy converters (WECs). Being able to capture hydrodynamic non-linearities, CFD-based NWTs (CNWTs) allow the analysis of WECs over a wide range of test conditions, such as sea states, power take-off control settings and model scale. The capabilities of a CNWT are exploited in this paper, which aims to analyse of the scaling effects of two moored point-absorber type WECs, exposed to focussed waves. To this end, three different scales are considered: 1:1, 1:10 and 1:10PWT. The latter, 1:10PWT scale, refers to the typical scale used in physical wave tanks (PWTs), complying with Froude scaling, but violating Reynolds scaling. In the 1:10 scale model, fluid viscosity is scaled, in line with the geometric properties, thereby achieving both Froude and Reynolds similitude. From the results, average differences between the three considered scales of around 5% have been observed, and the overall greatest sensitivity to scale effects can be found in the surge and pitch degree of freedom.
Internets in the sky: capacity of 3D wireless networks

Consider n nodes located in a sphere of volume V m/sup 3/, each capable of transmitting at a data rate of W bits/sec. Under a protocol based model for successful receptions, the entire network can carry only /spl Theta/(WV1/3n2/3) bit-meters/sec, where 1 bit carried a distance of 1 meter is counted as 1 bit-meter. This is the best possible performance even assuming the node locations, traffic patterns, and the range/power/timing of each transmission, are all optimally chosen. If the node locations and their destinations are randomly chosen, and all transmissions employ the same power/range, then each node only obtains a throughput of /spl Theta/(w/(nlog/sup 2/n)1/3) bits/sec, if the network is optimally operated. Similar results hold under an alternate physical model where a minimum signal-to-interference ratio is specified for successful receptions. The proofs of these results require determination of the VC-dimensions of certain geometric sets, which may be of independent interest.
Online disclosure practices of halal-friendly hotels

Purpose This research analyses the online disclosure practices of halal-friendly hotels, denoting their service provision within “halal” expectancies. This study aims to discover the halal attributes commonly used in the online marketing practices of halal-friendly hotels. Design/methodology/approach The methods used in this study include a deductive approach through literature, which was then followed by an initial investigation of several random samples that produced 24 points of halal-friendly attributes, and then content analysis to find out the online disclosure practices of 55 halal-friendly hotels. Further insights gathered through analysis of the use of Islamic images and symbols; also, by examining the nexus between the disclosure level and other variables such as halal-friendly certification level, star-level and guest ratings. Findings The results show that most hotels classify themselves as halal-friendly by providing information that articulates Islamic identity or by informing the existence of prayer facilities. Information displayed includes halal food, halal places, alcohol-free policy, prayer facilities and Qibla direction. Furthermore, image analysis shows that almost all hotels use human photographs, and the preferred gender is male; only a few hotels expose Islamic symbols. Most hotels maintain a neutral impression by avoiding “Islamised gender” and not overly emphasising Islamic images. Otherwise, halal-friendly certification level is positively correlated with the disclosure level. Practical implications The results provide a fresh insight regarding the online marketing practices of the halal-friendly hotels and could be used as a benchmark by the practitioners. Originality/value This topic is still unexplored; it shows this research originality.
View from the small chair: clients talk about their experiences of therapy

Relatively little research has been carried out into experiences of clients in therapy and/or counselling. There is even less regarding the understandings of experiences perceived as negative by the clients of therapy. Consequently, the purpose of the present research was to examine the experiences of clients that have experienced dissatisfaction in their encounter of psychotherapy. This is done by investigating the experiences and conceptualisations of nine participants who self-reported as having had a negative experience of their treatment. A grounded theory is applied in the research process resulting in three categories (client expectations; feeling unheard and the delicate dance of power) and five subcategories (safety within these four walls, alternative interpretations; same destination; view from the small chair and letting go) that contributed to participants labelling their experience as negative. The implications of these findings towards the best practise are discussed.
Face Detection in Curvelet Domain

Face detection and face recognition are two techniques in the field of image processing which have undergone significant research during the past few years. It stems from the availability of powerful algorithms, hardware and the wide range of applications they have got. Though powerful hardware and algorithms are available, today's face detection systems are far from perfect since they work within certain constraints. The performance of a face detection system is affected by the factors such as illumination, pose, occlusion etc. An efficient algorithm is the one which takes into account all the above factors, which would in turn increase the time complexity. Since time complexity acts as the bottleneck, development of an algorithm which detects face in minimum time is the need of the hour. Computations will take less time if a sparse representation can be provided for the image. Curvelet transform is an analysis tool which has the ability to sparsely represent images with curve discontinuities. In this work, curvelet transform is studied and is used to represent face images. Principal component analysis is done on this representation to reduce the dimension of the data. Euclidean distance is the parameter used to classify the face from non-faces. The performance of the system is analyzed using receiver operating characteristics (ROC).
Moving ship detection based on context modeling and motion analysis

Port surveillance systems play an import role in managing ship traffic and controlling the waterway security. As a crucial task in port surveillance systems, video-based automatic ship detection becomes important it offers high detection efficiency combined with low costs in installation and maintenance. In the last decade, some papers proposed various approaches to perform ship detection in different circumstances. There are two main types of techniques that are mainly discussed in the research papers: background substraction and appearance modeling. For background substraction, the highly dynamic water regions and complex surroundings as background easily lead to failures. Moreover, such approaches are not functional in non-static camera-based system. The appearance modeling methods largely rely on the local features, which leads to errors because ships have various appearances. This paper targets an automatic ship detection system functioning on both static and moving cameras. We explore the context information and facilitate ship detection by analyzing the motion similarity and saliency. We evaluate our system and show that it outperforms two recent approaches.
Experimental Study Of Atmospheric 3DDispersion Of A Passive Tracer In UrbanEnvironment: Comparison With Briggs UrbanModel

FluSAP 2010, a part of a large federative research program Vegdud (2010–2013) funded by the French National Research Agency, is an experimental campaign aiming to improve our knowledge on the dispersion of a plume in heterogeneous urban zones. For this, the French Institute for Radiological Protection and Nuclear Safety (IRSN) conducted an experimental campaign in the city of Nantes (France) to study atmospheric dispersion. A gas tracer SF6 was released in the atmosphere and measured at different altitudes (from 1 to 100 m) by using a mast and a small tethered balloon. This allows determining the plume vertical dispersion in an urban area as a function of atmospheric turbulence. A sampling system was also used at ground (1 m height) in order to evaluate the plume horizontal dispersion. All these systems were placed at a distance from the emission point between 20 and 1150 m: 30 SF6 emissions were performed between May 18 and May 27, 2010. High compatibility was found between experimental horizontal and vertical widths of the plume and Briggs urban model for the stability class B, C and D according to Pasquill classification. However, this compatibility was only confirmed for small distances from the source (till 370 m). For higher distances from the source, it is hard to draw significant conclusions.
UAV and Airborne LiDAR Data for Interpreting Kinematic Evolution of Landslide Movements: The Case Study of the Montescaglioso Landslide (Southern Italy)

Airborne remote sensing systems are increasingly used in engineering geology and geomorphology for studying and monitoring natural hazardous scenarios and events. In this study, we used two remote sensing monitoring techniques, i.e., light detection and ranging (LiDAR) and unmanned aerial vehicles (UAV) to analyze the kinematic evolution of the Montescaglioso landslide (Basilicata, Southern Italy), a large rain-triggered landslide that occurred in December 2013. By comparing pre- and post-event LiDAR and UAV DEMs and UAV orthomosaics, we delineated landslide morphological features and measured horizontal displacements and elevation change differences within landslide body. Analysis of two subsequent post-events digital terrain models (DTMs) also allowed the evaluation of the evolutionary behavior of the slope instability, highlighting no signs of reactivation. The UAV-derived digital surface models (DSMs) were found consistent with the LiDAR-DTMs, but their use was in addition highlighted as highly effective to support geomorphic interpretations and complement LiDAR and field-based data acquisitions. This study shows the effectiveness of combining the two UAV-LiDAR methodologies to evaluate geomorphological features indicative of the failure mechanism and to interpret the evolutionary behavior of the instability process
The effect of organizational culture on knowledge management practices and innovation

In this paper we analyze the relationships between certain knowledge management (KM) practices, organizational culture, and the technological results of companies. In the last few years, KM literature has highlighted the important role of cultural values on the way KM processes are developed and applied in organizations. From this viewpoint, and focusing on a set of knowledge storage and transfer practices, we try to empirically analyze the existence of a multiplier effect of the knowledge-centered organizational culture on the relationship between these kinds of knowledge practices and the technological performance of firms. The results of the empirical study show the existence of a significant moderating effect, although the consequences on the innovative performance in terms of product or process technologies are found to be different, depending on the practice (storage or transfer) which is considered.
