Summary In this study, we explore the theoretical model and structural dimensions of employee well‐being (EWB) in organizations. Specifically, using both qualitative quantitative methods, find that EWB comprises three dimensions: life well‐being, workplace psychological well‐being. We establish reliability validity newly developed scale through a series studies, which indicate is significantly correlated with affective organizational commitment job performance based on data collected from...

We describe the development and evaluation of a tool, iSonic, to assist users with visual impairment in exploring georeferenced data using coordinated maps tables, augmented nontextual sounds speech output. Our in-depth case studies 7 blind during 42 hours collection, showed that iSonic enabled them find facts discover trends data, even unfamiliar geographical contexts, without special devices. design was guided by an Action-by-Design-Component (ADC) framework, which also applied...

This paper studies contract strategy for two competing supply chains selling a substitutable product under demand uncertainty. Each chain consists of risk neutral manufacturer and averse retailer. As Stackelberg leader in each chain, needs to decide which type provide its retailer, either revenue sharing or wholesale price contract. We identify the conditions should be offered competitive market, is preferred by manufacturers only, both retailers. show that contracts may better choice than...

System administrators work with many different tools to manage and fix complex hardware software infrastructure in a rapidly paced environment. Through extensive field studies, we observed that they often build share custom for specific tasks are not supported by vendor tools. Recent trends toward web-based management consoles offer advantages but put an extra burden on system administrators, as customization requires web programming, which is beyond the skills of administrators. To meet...

Purpose. This study aims at evaluating the effectiveness of sonification as a mean to provide access geo-referenced information users with visual impairments.Method. Thiry-five participants (10 congenitally blind, 10 acquired blindness and 15 blindfolded sighted) completed four tasks progressive difficulty. During each task, first explored sonified map by using either tablet or keyboard move across regions listened sounds giving about current location. Then were asked identify, among tactile...

Auditory information is an important channel for the visually impaired. Effective sonification (the use of non-speech audio to convey information) promotes equal working opportunities people with vision impairments by helping them explore data collections problem solving and decision making. Interactive systems can make georeferenced accessible impairments. The authors compare methods using sound encode patterns navigating maps.

Interactive sonification (non-speech sound) is a novel strategy to present the geographical distribution patterns of statistical data vision impaired users. We discuss design space with dimensions interaction actions, representation forms, input devices, navigation structures, and sound feedback encoding. Two interfaces were designed, one using keyboard another smooth surface touch tablet. A study three blind users shows that they are able perceive 5-category values on both familiar unknown...

According to security demands of video conference system, this paper presented three schemes encrypt parts data using permutation code and DES encryption algorithm based on the newest coding standard H.264. Comparing with effects two algorithms respectively, determined one as a last scheme. This scheme adopts motion vector residuals after transform quantization before entropy encoding, some codewords DCT coefficients residual in stream, which includes TrailingOnes signs Levels RunBefore. It...

Abstract This paper describes a pixel‐based technique that enables highly interactive Web choropleth maps for georeferenced data publishing and visual exploration. Instead of delivering geographic knowledge to the client in polygon‐based vector formats, we encode object IDs shape information into compact pixel images (decoding maps). allows combination raster characteristics while avoiding problems currently existing (raster‐image‐based) or vector‐based techniques. Differing from traditional...

iSonic is an interactive sonification tool for vision impaired users to explore geo-referenced statistical data, such as population or crime rates by geographical regions. Users use a keyboard smooth surface touchpad interact with coordinated map and table views of the data. The integrated musical sounds speech allows grasp overall data trends get more details. Scenarios are described.

We demonstrate three versions of YMap, a dynamic choropleth map tool for geo-referenced statistical data explorations. More details can be found in (Zhao et al. 2003)First we present the Visual Basic desktop version. Users quickly visualize distribution attribute on by shading using that attribute, brush tightly coupled scatterplot, map, and detail window, formulate conjunctive queries view query results immediately scatterplot adjusting double-thumb sliders, or zoom pan to observe patterns...

This paper describes an investigation of using interactive sonification (non-speech sound) to present geo-referenced statistical data vision-impaired users for problem solving and decision making. By working with users, the work will identify effective interaction sound designs data, derive principles that can guide general auditory information seeking.

SOAP is the basis of Web Services application, and, messages are glue heterogeneous Services. Secure transit plays a critical role for applicability The main challenges to secure includes: confidentiality, authentication, integrity, both- party nonrepudiation, and single sign-on. Analyze take advantage existing technologies solutions related Services, model transmission developed, adopting like XML Signature, Encryption, X.509 Certificate. Analysis represents that basic requirements towards...

Green space effectively maintains urban ecological environment, improves life quality, and promotes sustainable development. Taking Nanjing Greater Manchester as study cases, based on the land use data from remote sensing interpretation, this used a combination of mathematical statistics GIS spatial analysis methods to analyze evolution green patterns in terms general characteristics, gradient characteristics order provide scientific reference for protection development Nanjing. Results...

A heterogeneous structure supported Ni-Fe-P-Ni(OH)2/NF catalyst was prepared by chemical deposition method. The as-prepared composite exhibits remarkable electrocatalytic performance towards the hydrogen evolution reaction, requiring a low overpotential of 201 mV at current density -100 mA cm-2. Notably, also demonstrates exceptional oxygen performance, achieving 100 cm-2 with only 294 overpotential. Moreover, its in overall water splitting, serving as both cathode and an anode, showcases...
