Social connectedness is an indicator of the extent to which people can realize various network benefits and therefore a source social capital. Using case Twitter, theoretical model based on functional structural characteristics people's communication behavior within online developed tested. The study investigates how presence, awareness, influence each other, when for whom effects presence awareness are most strongly related positive outcomes in connectedness. Specifically, looks at...

In recent years, interaction designers have actively started addressing sustainability as a research topic. More specifically, persuasive applications, which aim at promoting pro-environmental behaviour, such energy saving been of growing interest in multiple disciplines. Driven by the proliferation smart meters and monitors well rise social media, researchers applications developed wide range design solutions that address this issue. The majority them, however, provide same information to...

Purpose Coordination in supply chains and networks calls for information sharing among the members of chain. Accordingly, visibility – availability relevant making chain related decisions is an important concept context management. The purpose this paper to identify different dimensions propose a framework based on these dimensions. proposed can be used evaluate systems (SCIS) their contribution towards chains. Design/methodology/approach Using framework, we compare two SCIS (SAP APO...

This paper uses cognitive fit theory to analyze the problem solving process in spreadsheet analyses. Cognitive proposes formation of mental representation as a part process. However, there is little research examining representation, which key concept theory. study examines and an alternative mechanism between different representations their corresponding when task invariant, but changes. Mental then empirically assessed based on application Hick’s law, states that response time users making...

Errors in spreadsheets pose a serious problem for organizations and academics. This has resulted ongoing efforts to devise measures reducing errors or efficient ways of correcting them. Visualization tools are often advertised as means improving spreadsheet error correction performance. study investigates the role visualization correction. For this purpose, proposes framework classifying activities associated with The is highlight that important different types errors, show how can aid by...

Designing computer-human interfaces for multiple-goal environments is challenging because people pursue multiple goals with conflicting priorities. Safety-critical environments, such as driving, aggravate the need a more nuanced understanding of that may reconcile tasks. Speech are prime examples interfaces. In this article, we investigate how design variations an in-vehicle speech interface influence performance primary task (driving safely) and secondary (e-mailing). controlled experiment,...

This paper describes the design and evaluation of NFriendConnector, a prototype application that allows for better integration between online offline social networks. Online networks are currently used to maintain strengthen existing real-life connections, rather than establishing ties exist only online. However, users incur significant time search related costs in replicating naturally occurring interaction using networking site (SNS). Therefore, there exists gap initiating contact versus...

The outage and average symbol error rate of a single channel system are analyzed over two-wave diffused power (TWDP) fading channels. An expression characteristic function probability signal-to-noise ratio (SNR) for TWDP have been derived. Probability distribution based approach has followed to derive expressions different coherent noncoherent M-ary modulation schemes. Effects the types parameters K A on performance studied. results obtained verified with special case available in literature...

With the availability of online consumer reviews, consumers' consumption behaviors are gradually changing. They increasingly relying on reviews for information prior to purchase. The influences sales have been identified and verified by many empirical studies. However, little research has explored how review content characteristics affect trustworthiness in (TIOCR) willingness purchase (WTP) experience goods. Based signaling theory related literature, we construct a model explain TIOCR WTP...

Modern mechatronic Product-Service Systems (PSS), as a combination of mechanics, electrics, electronics, software and services, require an interdisciplinary system understanding development process. During the development, each discipline uses specific modeling languages tools, which focus on certain aspects system. However, much model information is commonly used in different disciplines involved. Thus, it inefficient to these elements separately from scratch every thereby keep data...

During the development of product-service systems (PSS), various artifacts are modeled by different involved disciplines, e.g. mechanics, electrics, electronics, software and services. Each these represents aspects PSS as a whole. In order to reuse respective information that contained in each artifact but which represented using ways modeling, transformations needed. this paper we present conceptual methodology how relevant elements their attributes can be transformed from one specific...

Enabled by Internet-based technologies, users are increasingly participating and collaborating in idea generation online innovation communities. Beyond increasing the quantity of ideas contributed users, firms looking to obtain better quality. However, with limited understanding phenomenon, few studies have focused on investigating what determines quality collaboratively generated user This study aims address this knowledge gap antecedents from a collaboration perspective. Based perspective,...
