| Social Media Analytics with Facebook -- The Case of Higher Education Institutions | | BIBAK | Full-Text | 3-12 | |
| Claudia Brauer; Edward W. N. Bernroider | |||
| Social Media Analytics has developed into a new research field within
information science in the last years. Due to this fact, currently only a few
research results about the usage of Social Media Analytics exist. To fill this
gap, we conducted an international delphi study among selected higher education
institutions (HEIs) in Germany, Austria and Switzerland which are applying
Social Media Analytics related to Facebook. The results demonstrate that the
majority of HEIs use more than one Social Media Analytics software tool and
consider different Facebook metrics pre-dominantly on a monthly basis to
evaluate and to develop their Facebook activities. We conclude that many HEIs
lack an integrated Social Media Analytics strategy, under-utilize the real-time
capabilities of Social Media Analytics and would benefit from Social Media
Analytics. Keywords: Social Media Analytics; Social Media Analytics metrics; Facebook;

| Engaging Online Review Writing Experience: Effect of Motivational Affordance on Review Quality | | BIBAK | Full-Text | 13-21 | |
| Xiaofang Cai; Patrick Y. K. Chau | |||
| Online review has become an important repository for consumers to make
online buying decisions. However, writing online reviews is a voluntary
behavior lacking guidelines and it is hard to guarantee the review quality
generated. How to improve online review quality has become a challenge to
online retailers and review aggregators. In this study, we explore the design
of review writing interface in order to provide engaging writing experience for
online reviewers. Using the motivational affordance theory as the theory basis,
we define the motivational factors and corresponding design elements, which
support reviewers to fulfill their motivation to write their online reviews. We
explore how the engaging experience supported by cognitive and social
affordances will affect reviewers' writing performance. Keywords: Motivational affordance theory; Online review quality; Engagement; Social
presence; Review writing; Interface design | |||
| Topic-Based Stance Mining for Social Media Texts | | BIBA | Full-Text | 22-33 | |
| Wei-Fan Chen; Yann-Hui Lee; Lun-Wei Ku | |||
| Recent techniques of opinion mining have succeeded in analyzing sentiment on the social media, but processing the skewed data or data with few labels about political or social issues remains tough. In this paper, we introduce a two-step approach that starts from only five seed words for detecting the stance of Facebook posts toward the anti-reconstruction of the nuclear power plant. First, InterestFinder, which detects interest words, is adopted to filter out irrelevant documents. Second, we employ machine learning methods including SVM and co-training, and also a compositional sentiment scoring tool CopeOpi to determine the stance of each relevant post. Experimental results show that when applying the proposed transition process, CopeOpi outperforms the other machine learning methods. The best precision scores of predicting three stance categories (i.e., supportive, neutral and unsupportive) are 94.62%, 88.86% and 10.47%, respectively, which concludes that the proposed approach can capture the sentiment of documents from lack-of-label, skewed data. | |||
| What Do Patients of Different Medical Illness Say About Their Doctors Online? An Analysis of Online Physician Reviews | | BIBAK | Full-Text | 34-40 | |
| Ming-Hsin Phoebe Chiu; Chia-Lin Chang | |||
| This study aims to understand the role and function of online physician
reviews as a process of health information communication, as well as the
applications on medical practice and patients and caregivers' medical
decision-making process. It collected online physician reviews from two
Taiwan-based health information websites -- Good Doctor and Health and DocHos.
The analysis framework comprised four aspects: (1) length of reviews; (2)
moment in the medical encounter process is reviewed; (3) themes of the reviews;
and (4) review intents. In addition to analyzing the structural and textual
characteristics of online physician reviews, this study took a step further to
identify the relationship between patients of different medical and how they
evaluated a medical encounter. In this paper, findings were reported and
implications in improving physician-patient communication and patients'
empowerment were discussed. Keywords: Online physician review; Content analysis; Physician-patient communication;

| Privacy by Design: Examining Two Key Aspects of Social Applications | | BIBAK | Full-Text | 41-52 | |
| Ben C. F. Choi; Joseph Tam | |||
| Social applications do not only acquire users' personal information but
potentially also collects the personal information of users' social networks.
Despite considerable discussion of privacy problems in prior work, questions
remain as to how to design privacy-preserving social applications and how to
evaluate its effect on privacy. Drawing on the justice framework, we identify
two key aspects of social, namely information acquisition and exposure control
and examine the effects on user evaluation of social applications. Furthermore,
we investigate the impact of this evaluation on usage intention. In doing so,
we provide new insight into embedding privacy in technology development. Keywords: Social applications; Online social networks; Information privacy | |||

study examines consumer evaluations of a real CRM product brochure and a
fraudulent one that imitates it. The forged brochure contains malicious
manipulations designed to decrease trust in the product and oversell the
abilities of the CRM system. This study seeks to see how manipulations of the
material are perceived by the individuals and how that impacts their
willingness to believe the source credibility of a message. Keywords: Source credibility; Deception; Trust; Media assurance | |||
| Understanding the 'Quality Motion' of Wikipedia Articles Through Semantic Convergence Analysis | | BIBAK | Full-Text | 64-75 | |
| Huijing Deng; Bernadetta Tarigan; Mihai Grigore; Juliana Sutanto | |||
| To better inform the users of the articles quality, Wikipedia assigns
quality labels to the articles. While most of the existing studies of the
Wikipedia phenomenon took the quality ratings provided by Wikipedia as the
outcome variable of their research, a few yet growing number of studies ask
expert raters to rate the quality of selected Wikipedia articles because of
their doubts in Wikipedia's ratings. This study aims to check if Wikipedia's
ratings really reflect its stated criteria. According to Wikipedia criteria,
having abundant and stable content is the key to article's quality promotion;
we therefore examine the content change in terms of quantity change and content
stability by showing the semantic convergence. We found out that the quantity
of content change is significant in the promoted articles, which complies with
Wikipedia's stated criteria. Keywords: Wikipedia; Article quality; Quality motion; Content change; Semantic

| Social Media in Health Care | | BIBAK | Full-Text | 76-85 | |
| Brenda Eschenbrenner; Fiona Fui-Hoon Nah | |||
| To identify existing streams of research and develop an agenda for future
research, we reviewed and synthesized the existing literature relevant to
social media in health care. In particular, our review encompassed two themes
-- Patient Use of Social Media and Healthcare Organization/Professional Use.
Within these overarching themes, we focused on four subthemes (i.e., two under
each main theme): community/public health and patient support/use, as well as
medical litigation & compliance risk and health education & information
sharing. From this review, we have also proposed future research topics and
questions to further cultivate this salubrious research domain. Keywords: Social media; Health care; Patient social media use; Healthcare organization

| The Value of Expert vs User Generated Information in Online Health Communities | | BIBA | Full-Text | 86-95 | |
| Jie Mein Goh; Elena Yndurain | |||
| Online health communities are becoming an important source of information whereby users of these platforms, especially patients, participate for knowledge sharing and emotional support. This research examines the perceived value of expert generated information and user (patient) generated information and how it is influenced by different types of information that a user seeks. First, we propose a framework to classify the types of information based on the different types of information patients typically seek out on online health communities using a knowledge based perspective. Then based on this framework, we provide a set of propositions on the perceived value of expert generated versus user driven responses derived by patients. We expect that expert generated responses to have greater perceived value by patients as compared to community driven responses depending on the type of information patients are asking. Specifically, information uncertainty requiring tacit knowledge and high affect such as treatment experiences has greater value when generated by other patients. On the other hand, information uncertainty requiring explicit knowledge and low affect such as understanding the nature of diseases has greater value when generated by expertise. The proposed framework can help to extend the line of research on online health communities and inform health professionals, health organizations or developers of such communities. | |||
| A Study of the Uses of Instant Messaging in the Government Offices | | BIBAK | Full-Text | 96-105 | |
| Rachael K. F. Ip; Akina K. W. Ho | |||
| In recent decades, the pervasiveness of information and communication
technologies (ICTs) has changed the communication patterns of the majority of
the Internet users. This phenomenon is further intensified by the popularity of
instant messaging (IM) chat. IM-chat has not only impacted on personal social
communication, but also has significantly changed the way organizations
communicate internally and externally. This study aims at examining the impact
of three personal level factors on workplace IM uses and the associated
communication satisfaction. Our findings reveal that habit and boundary
crossover have positive impact on workplace IM uses and communication
inhibition has a positive influence on the relationship between workplace IM
uses and the associated communication satisfaction. Based on our findings,
implications for research and practices are discussed. Keywords: Instant messaging; Habit; Boundary crossover; Spiral of silence;

| Leveraging Social Media for the Fishing Industry: An Exploratory Study | | BIBAK | Full-Text | 106-117 | |
| Azrin Shah Ismail; Haliyana Khalid | |||
| One of the main challenges in the fishing industry today is the art of
connecting buyers and sellers effectively so that information about products,
price, quantity and location is synchronized. A lack of communication and
technology skills has forced fishermen and fishing industry authorities to
depend on intermediaries to market their products, leading to higher prices for
consumers. This paper explores the potential use of social media to reduce
intermediaries in the fishermen market supply chain. It also aims to understand
the critical success factors in using social media as a platform to promote the
market. Keywords: Fishing industry; Fishermen; Social media; Social media marketing;

| The Design of IdeaWorks: Applying Social Learning Networks to Support Tertiary Education | | BIBAK | Full-Text | 118-129 | |
| Lele Kang; Shaokun Fan; J. Leon Zhao | |||
| Online education has progressed from having students passively read and
watch materials to having them proactively engage in interactions with other
students and teachers. Social network technologies enable students to interact
with each other, leading to a new platform for online education. Based on the
social learning theory, we design a new social learning network system, named
IdeaWorks. Two empirical studies, a usability study and an impact study, were
conducted to examine how the social learning network system (i.e., IdeaWorks)
has an impact on students' learning activities. The results of the usability
study show that IdeaWorks' design performs well on user interface,
functionality, and process. Generally, users have a high level of usage
intention towards IdeaWorks. The results of the impact study show that learning
via IdeaWorks, as well as learning in traditional classrooms, enables users to
perceive a high level of social presence, cognitive presence, satisfaction with
the course, and satisfaction with the group. However, the impact study also
showed that we should enhance IdeaWorks to support instructional communication
and group communication in the context of online education. Keywords: IdeaWorks; Social learning networks; Online education; E-learning | |||
| Contribute Knowledge Continuously or Occasionally? | | BIBAK | Full-Text | 130-141 | |
| Yi-Cheng Ku; Chih-Hung Peng; Chih-Ping Wei; Yin-An Chen | |||
| This study focuses on continued knowledge contribution. We hypothesize that
continued knowledge contribution of members in opinion-sharing communities is
influenced by five factors: the number of reviews written, the average of
helpfulness scores received from other members, the average of helpfulness
scores given to other members, the ratio of the number of negative reviews to
the total number of reviews, and the number of trustors. We collect data from
Epinions.com and find that these five factors have significant impacts on
continued knowledge contribution. These findings have significant theoretical
and practical implications for knowledge sharing. Keywords: Knowledge contribution; Knowledge contributor; Online community; Trust

| The Effect of Structural Holes on Social Capital and Individual Performance Within Social Media Networks | | BIBAK | Full-Text | 153-164 | |
| Yoanna Long; Roberto Mejias | |||
| The increasing use of social media has transformed the way that individuals
interact with each other and has accelerated the exchange of information and
knowledge. Social media has also created the phenomenon of social capital
defined as the expected collective or economic benefit derived from the
cooperative interaction between individuals and groups. Our research paper
explores the effect on structural holes on social capital and participant
performance. Structural holes have been defined as weak links to other social
media groups outside the primary social network group. Research posits that
weak links generate more alternate sources of new information and knowledge
than strong links and thus, create more social capital and affect individual
performance within a social network. Our results discuss the effect of
frequency of user logins, posts counts and hierarchy (as a measure of
structural hole) on experience and activeness as a measure of individual
performance. Keywords: Social media networks; Social capital; Structural holes; Hierarchy; Virtual

| Serving the Social Customer: How to Look Good on the Social Dance Floor | | BIBAK | Full-Text | 165-174 | |
| Nicola J. Millard | |||
| Customers are increasingly coming to expect brands to deliver customer
service on the social media dance floor. The dilemma is that brands don't
always understand the mechanics of the dance. The first step to looking good on
the social media dance floor is to watch and listen to the dancers -- so this
study investigates what customers are actually engaging with on social media
(primarily Twitter, Facebook and forums) with respect to brands. It takes two 1
week snapshots of customer (not brand) activity on social media for 13 brands
in 6 vertical sectors across 2 time periods (one sample during 2011 and one in
2014). We discovered that customers were actively engaging with brands on a
number of levels -- from complaints to complements and beyond -- that different
sectors had different challenges, that saying sorry wasn't necessarily enough
to satisfy customers and that social dancing often requires brands to do a
coordinated conga through multiple channels and complex internal processes. Keywords: Social media; Customer experience; Omnichannel; Customer relationship

| Are Spectacles the Female Equivalent of Beards for Men? How Wearing Spectacles in a LinkedIn Profile Picture Influences Impressions of Perceived Credibility and Job Interview Likelihood | | BIBAK | Full-Text | 175-184 | |
| Sarah F. van der Land; Lotte M. Willemsen; Suzanne A. J. Unkel | |||
| This study builds on our previous work on beardedness [1] and explores
whether wearing spectacles in a LinkedIn profile picture affects a female
candidate's prospects of being invited for a job interview and whether this is
contingent on the type of job vacancy. Results of a 2 (spectacle use:
spectacles versus no spectacles) × 3 (job type: expertise,
trustworthiness, attractiveness) experiment conducted among 139 participants
show that bespectacled candidates are perceived as having more expertise and --
to our surprise -- also being more attractive than candidates not wearing
spectacles. Moreover, a candidate's perceived credibility is a significant
predictor of the intention to invite the candidate for a job interview.
Theoretical and practical implications of these findings are discussed. Keywords: Personal branding; Strategic social media; Impression management;

| Mining Social Media for Enhancing Personalized Document Clustering | | BIBAK | Full-Text | 185-196 | |
| Chin-Sheng Yang; Pei-Chun Chang | |||
| Social media is nowadays an excellent platform for gathering user
intelligence for supporting business intelligence applications. Social tagging
system (aka. folksonomy) is a critical mechanism for collaboratively creating,
organizing and managing the wisdom of crowds. The knowledge gained from social
tagging system should be tremendous assets for conducting and improving various
business intelligent applications. Consequently, the purpose of this study is
to examine the values of folksonomy on an important business intelligent task,
namely personalized document management. Specifically, we employ Delicious, a
pioneered social bookmarking service, to construct a statistical-based
thesaurus which is then applied to support personalized document clustering.
According to our empirical evaluation results, social tagging system indeed
improve the quality of the statistical-based thesaurus in comparison with that
constructed on the basis of a general-purpose search engine in generating
personalized document clusters. Keywords: Social media; Business intelligence; Social tagging; Social bookmarking;

| The Influence of Individual Affective Factors on the Continuous Use of Mobile Apps | | BIBAK | Full-Text | 197-206 | |
| Yi-Hsuan Yeh; Belinda Chen; Nien-Chu Wu | |||
| Mobile apps have attracted a substantial amount of attention in mobile
commerce. Usage behavior of consumers is always an important issue in this
research area. The objective of this study is to explore what factors will
affect an individual's continuance intention to use mobile apps. We proposes a
research model that integrates the Task-Technology Fit (TTF) and Theory of
Reasoned Action (TRA), which are augmented with concepts of affective factors.
We conduct an online survey and the results show that a higher degree of TTF
and VTF (Value-Technology Fit) resulted in a more positive attitude towards
using the mobile app. SN and attitude had strong significant impacts on users'
continuance intention to use the app. However, TTF and VTF had no significant
effect on the continuance intention to use the app. Keywords: Mobile apps; Task-Technology Fit; Value-Technology Fit; Subjective norm | |||
| Identifying Appraisal Expressions of Online Reviews in Chinese | | BIBAK | Full-Text | 207-218 | |
| Pei Yin; Hongwei Wang; Wei Wang | |||
| With the development of Web2.0 technology, an increasing number of consumers
are giving comments on products over the Internet, thus opinion mining rises in
response to the requirement of retrieving valuable information in speed. After
thoroughly analyzing the style of language and the ways of expression in
Chinese, this paper proposes a semantic lexicon-based method to identify the
appraisal expressions in Chinese online reviews. A comparative experiment based
on cellphone online reviews in Chinese is conducted in this research, and the
result indicates that the proposed method is quite promising and outperforms
the two baselines (a statistic orientation method and a semantic orientation
method). Moreover, the method is applied to a comparative evaluation of two
popular cellphones, demonstrating the theoretical significance and the
practical value of this research. Keywords: Online reviews; Appraisal expressions; Product feature; Review feature;

| Situation-aware information assistance strongly depends on the quality of available contextual background knowledge for an application domain and on its automatic processing. In this paper we present a conceptual approach towards using cognitive architectures to provide information assistance and allow complex decision making based on expert knowledge. We transfer our approach into a technical concept which was finally implemented as part of the Plant@Hand assembly assistance system within a mobile workshop trolley. The paper gives insights into our work on formalizing knowledge and providing ad-hoc mechanisms for planning, assisting and controlling assembly tasks on the manufacturing shop floor. | |||
| An Interactive Assessment Instrument to Improve the Process for Mobile Service Application Innovation | | BIBAK | Full-Text | 244-255 | |
| Karen Carey; Markus Helfert | |||
| In recent years, the adoption and use of new mobile service applications
have not proliferated, consequently many applications fail to generate a profit
[1, 2]. One reason for this is poor decision making in the process of mobile
service innovation [1, 3, 4]. This paper details the construction of an
interactive assessment instrument to improve decision making in this innovation
process. To design the interactive assessment instrument, we follow a Design
Science Research Methodology (DSRM) -- a methodology which is new to HCI [5].
Adhering to the DSRM, the paper details the iterative design and evaluation
cycles required to build and evaluate the instrument. The paper concludes that
the designed assessment instrument improves the innovation process, by
providing transparency, while also facilitating communication and understanding
amongst team members. Additionally, the paper demonstrates that the DSRM can be
of great use to design and evaluate interactive IT artifacts within the HCI
field. Keywords: Mobile service applications; Innovation process; Interactive assessment

| The Influence of Location and Social Network on Customers' Acceptance of Mobile Marketing: Evidence from Group Buying Field Experiment | | BIBAK | Full-Text | 256-266 | |
| Xi Chen; Ruibin Geng; Chee Wei Phang | |||
| With the rapid development and widespread popularity of smart phone devices,
location-based social networking service (LBSNS) creates an era of GeoLife2.0
where people can share life experiences and connect to each other with their
location histories. Previous academic studies have also realized the crucial
role of location and social network on mobile marketing. However, many of them
have been conceptual work using structural equation modeling, and the effects
of these two factors are never considered at the same time. In our study,
mobile marketing is exemplified as a time-limited, group-based "two for the
price of one when you get a friend to buy together" promotion campaign
advertised via mobile devices. Field experiment was conducted to explore the
influence of location and social network on consumers' decision to accept
mobile promotions. We then conducted follow-up surveys that revealed users'
personality features and psychological states as supporting materials to
explain our field experiment observations. Keywords: Location-based social networking service; Field experiment; Mobile

| Dishonest Behavior at Self-Service Checkouts | | BIBAK | Full-Text | 267-278 | |
| Susan Creighton; Graham Johnson; Paul Robertson; Jan Law; Andrea Szymkowiak | |||
| Self-service technology could be argued as creating less personal
transactions when compared to traditional checkouts involving a sales assistant
for the entire transaction process, which may affect customer behavior. The aim
of our study was to investigate the perceived influence of social presence at
self-service checkouts by staff and its perceived effect on dishonest customer
behavior. Twenty-six self-service checkout staff took part in a series of
semi-structured interviews to describe customer behaviors with self-service.
With respect to actual physical social presence, staff reported that more
customer thefts occurred when the self-service checkouts were busy and their
social presence was reduced. Staff also reported that perceived and actual
social presence is likely to reduce thefts. Future research will elaborate to
which extent the perceived social presence via technological systems might
support staff in their task to assist customers and reduce dishonest behavior. Keywords: Self-service; Social presence; Dishonest behavior | |||
| Consumer Adoption of Social Commerce | | BIBAK | Full-Text | 279-287 | |
| Nick Hajli; Xiaolin Lin | |||
| The paper considers the emergent, so called, 'social commerce' imperative
which enables consumers to generate active WEB content and engage commercially
with providers through social networking systems. It is apparent that little
research currently addresses the need for an understanding of consumer adoption
in this respect and therefore further critical issues involved in contemporary
consumer research. Our contribution relates to a consideration of adoption
behaviour through the formulation of the technology acceptance model (TAM),
social commerce constructs and trust. We consequently present specific insights
into consumers 'intention to buy' through social commerce engagement. The
results of our research also inform providers with an initial important
awareness of the impact of social media within a commercial context. Keywords: Social commerce; TAM; Intention to buy; SEM-PLS | |||
| Helping Customers Help Themselves -- Optimising Customer Experience by Improving Search Task Flows | | BIBAK | Full-Text | 288-299 | |
| Sue Hessey | |||
| Large consumer-facing enterprises can offer a wide range of products and
services to their customers. In parallel, often the quantity of information
offered online to customers to support these services is similarly large in
scale -- so how can an enterprise optimize online support to improve customer
satisfaction and lower support costs to the business? To address this problem
we have used quantitative and qualitative methods to identify the most
significant topics concerning customers over a 14-week period. These analyses
in turn informed our user test design, which investigated individual
search-for-help behaviors. The output from these analyses was used to form
recommendations for high-priority, low cost interventions in the User Interface
design of the support website, so that customers are more willing and able to
help themselves. Keywords: Customer service; User Interface; Information search; Information retrieval | |||

| Chia-Yu Kao; Chenwei Chiang | |||
| This study targets middle and old aged players' mobile game participations,
as well as their purchase intention of virtual items, and an internet-based
survey is conducted. Results show that when players are in the flow channel,
motivations such as competition and self-assurance, game playability, artistry,
and sociability, increase players' purchase intention for virtual items. On the
other hand, entertainment of motivation and mobility of playability, decrease
players' willingness to purchase virtual items. Younger players demonstrate
significant difference than middle and old aged players on mobile games.
However, gaming market of middle and old aged players shouldn't be overlooked.
More in depth investigation of middle and old aged players' needs for mobile
games is helpful for designing better games and campaigns attracting middle and
old aged players, and increase their purchase intention for virtual items. Keywords: Mobile game; Game motivation; Game playability; UX | |||
| Key Factors in Developing Omnichannel Customer Experience with Finnish Retailers | | BIBAK | Full-Text | 335-346 | |
| Satu Peltola; Harri Vainio; Marko Nieminen | |||
| Change in consumer behavior towards increased use of digital services
throughout the buying process drives retailers to rethink their services.
Contemporary shoppers engage in a mixture of real-life and digital activities
combining events in brick-and-mortar stores with online and mobile browsing.
Our interviews with seven Finnish retailers show that the changing consumer
behavior affects not only services but also other operations including
organizational structure and supply chains. For analysis purposes, we modified
customer journey maps to record and illustrate user activity. We conclude that
a good omnichannel customer experience lies in the unity of retailer's
organizational culture, pricing, operations, and communications. Instead of
full-range digital and physical service offering, seamless and intuitive
linking of consumer touch-points appears as a promising path. Our results
contribute to better understanding of omnichannel customer experience
indicating the need for a more profound approach in omnichannel development to
more traditional channel and customer interface development. Keywords: HCI; Human-computer interaction; Omnichannel; Development; Customer

| The Role of Brand Loyalty and Social Media in E-Commerce Interfaces: Survey Results and Implications for User Interfaces | | BIBAK | Full-Text | 347-357 | |
| Dimitrios Rigas; Hammad Akhtar Hussain | |||
| This paper explores the role of brand loyalty and social media in e-commerce
interfaces. A survey consisting of 118 respondents was contacted to address the
questions relating to online shopping and brand loyalty. The issues
investigated included the link between the frequency of access and time spent
on an e-commerce user interface, and brand loyalty, gender and age profile
differences, and the role of social media to branding and on-line shopping. It
was found that online loyalty differs from offline loyalty and loyalty also
differed across genders, showing that males may develop loyalty easier than
females when shopping online. Information shared about products on social media
by friends and family played an important role in purchase decision making.
Website interface and ease of navigation were also key aspects for online
shopping. The research concluded with some pointers towards multimodal
interfaces that aid loyalty with the use of interactive multimodal social
media. Keywords: On-line consumer behavior; Brand loyalty; E-commence interfaces; Social

| The Mediating Role of Perceived Security: An Empirical Study of Mobile Wallet Adoption in USA | | BIBAK | Full-Text | 358-369 | |
| Norman Shaw | |||
| Because the USA is introducing 'chip and pin' card standards in 2015,
payment terminals are being implemented that have the capability of reading
plastic cards that are simply waved in proximity to the terminal. With the aid
of a 'mobile wallet' app, smartphones are able to substitute for the physical
card and complete contactless payments. The transaction flows through an
ecosystem that is comprised of the smartphone manufacturers, software
developers, mobile network providers and financial institutions. However,
consumer adoption has been slow and, in order to help practitioners with their
investment decisions, this study seeks to explain the factors that influence
intention to use. Theory extends the technology acceptance model with the
constructs of perceived security and personal innovativeness. An empirical
study supports the hypotheses and explains the mediating role of perceived
security. Keywords: Mobile wallet; Technology acceptance; Perceived security; Personal

(EPC) known as Productpedia. This collaborative EPC platform addresses numerous
shortcomings of prior researches by (1) maintaining a single centralized EPC
database; (2) negating the need to synchronize and convert data; (3) creating
an integrated meta-model ontology for merchants to define previously
unclassified product information without the involvement of domain experts; and
(4) enabling an Open Application Programming Interface based on RESTful web
services to facilitate direct modification of the EPC database by even
third-party applications. Keywords: Electronic product catalog; Ecommerce; Web 3.0; Web service; Design science | |||
| The Moderating Role of Perceived Effectiveness of Provider Recommendations on Consumers' Satisfaction, Trust, and Online Repurchase Intention | | BIBAK | Full-Text | 382-391 | |
| Hongpeng Wang; Rong Du; Shizhong Ai; Zhe Chi | |||
| Despite the importance of online provider recommendations in e-commerce
transactions, there is still little understanding about how provider
recommendations impacts on customer retention. Addressing this gap, this study
introduces a key construct, perceived effectiveness of provider recommendations
(PEPRs) to investigate the differential moderating effects of PEPRs on the
relationships between satisfaction, trust and repeat purchase intention. The
research models are designed based on a research model and an online survey is
conducted with 130 respondents. We draw conclusions that (1) PEPRs negatively
moderate the relationship between satisfaction with vendor and trust in vendor
and (2) PEPRs positively moderate the relationship between trust in vendor and
repurchase intention. These findings are important theoretical contributions to
know that first-hand experience can be to some extent replaced by supplementary
information. In addition, we give some managerial countermeasures towards the
new situation. Keywords: Provider recommendations; Satisfaction; Trust; Online repurchase intention | |||
| An Exploratory Study of Website Localization Strategies: The Effect of Exogenous Factors | | BIBAK | Full-Text | 392-402 | |
| Tailai Wu; Chih-Hung Peng; Yani Shi; Choon Ling Sia | |||
| This paper explores the relationship between website localization and their
exogenous factors. Three exogenous factors are studied: online transaction
availability, product types and history length. Based on the previous studies,
this paper distinguishes website localization design strategies from website
localization degree. Through a content analysis of Fortune 1000 companies'
websites, this paper finds that website localization strategies are positively
related to website localization degree and that product types positively
associate with website localization degree. Besides, all the exogenous factors
are relevant to some specfic website localization strategies. Keywords: Website localization; Exogenous factors; Strategies; Content analysis | |||
| Consumers' Purchase Intention of Online Product Customization Using Different Terminals with/without Default Template | | BIBAK | Full-Text | 403-413 | |
| Jiaheng Xie; Wangsheng Zhu; Kanliang Wang | |||
| To provide more personalized products, many vendors allow consumers to
design their products by selecting attribute by attribute, a technology
commonly called customization. Complexity of customizing process has been a
concern for consumers, and default template was introduced to solve this
dilemma. With the rapid development of mobile internet, mobile terminals, such
as tablets and smart phones, play ever vital roles in conducting e-commerce.
The shift from desktop computers to mobile terminals may generate changes in
the response of consumers viewing identical content as digital interfaces
fundamentally change the experience of the content they access. However, little
attention has been paid to the impacts of different terminals on consumers'
purchase intention. This research aims to find out the impact of default
template on consumers' purchase intention, and the interaction effect that
terminal and need for uniqueness have on the relationship. A lab experiment was
conducted to test the proposed hypothesis. The result shows that default
template increase consumers' intention to buy. Besides, terminal and need for
uniqueness have moderating effect on the relationship. Keywords: Default template; Terminal; Need for uniqueness; Intention to buy;

| An Empirical Study of User Decision Making Behavior in E-Commerce | | BIBAK | Full-Text | 414-426 | |
| Dongning Yan; Li Chen | |||
| The large number of customer reviews and inconsistent writing style make it
difficult for users to digest information and make online purchasing decisions.
In light of human decision making theory, an in-depth understanding of user
decision making behaviors serves as the foundation of effective information
displays. In this paper, we conduct a formative study to empirically
investigate user decision making behaviors in online hotel booking, in
particular, with respect to customer reviews. Through analysis of the results,
we identify the information decision makers are inclined to seek and the
decision strategies they utilize to process information in three stages of
online purchasing. Keywords: Customer review; E-commerce; Human decision making; User study | |||
| Exergames for Older Adults: Towards Sustainable and Transferrable Health Benefits | | BIBAK | Full-Text | 429-436 | |
| Young Anna Argyris; Taiwoo Park | |||
| This study presents an exergame called Pressure-Ball game that is designed
to increase health among institutionalized older adults. As many older adults
develop sedentary lifestyle in which their physical activities are reduced, it
is important to engage them in a mild exercise activity. The mild exercise
activity can increase their confidence in fitness levels and reduce fear of
injuries; thereby building active lifestyle that can be sustainable and
transferrable to other domains of life. To assess health benefits brought about
by Pressure-Ball game, we propose a longitudinal study that employs a series of
experiments in retirement homes in Midwest. The completed research has
potential to provide health benefits to aging population. Keywords: Exergame; Flow; Continued use of IS; Older adults; Healthcare IT | |||
| Reimagining Project Management Applications via Gamification | | BIBA | Full-Text | 437-445 | |
| Charles Butler | |||
| The objective of this paper is to present a prototype design of a project management application which has been designed to leverage the power of gamification. The specific set of gamified features contained within the prototype follow the model set forth in previous work which attempted to aid gamification designers in the selection and implementation of the most effective mechanics for whatever the intended purpose. This was done by mapping a number of gamification mechanics to existing effects in behavioral economics, which allows designers an unconventional insight into the behavioral reasons as to why various methods of gamification affect a user-base. It should also be noted that unlike some gamification implementations which can, at times, be seen in a negative light by being excessively game-like, the focus here is on bringing gamification into the business setting in a serious and professional manner in order to ease adoption among all users. | |||
| A Study on Mobile Fitness Application Usage | | BIBAK | Full-Text | 446-457 | |
| Ben C. F. Choi; Nathaniel T. Lee | |||
| Although the importance of physical activity in a healthy lifestyle is well
known, little attention has been paid thus far to systematically understand
users' continued usage of mobile fitness applications. The objective of this
paper is to understand the determinants of usage of mobile fitness applications
beyond initial adoption. The research model is tested with data collected from
fifty users of mobile fitness applications. The results indicate that
expectation confirmation is the key predicator of attitudes towards the
application, such as perceived usefulness, perceived enjoyment, and
satisfaction. Furthermore, users' attitudes are found to determine continued
usage intention. Overall, this paper contributes by integrating intrinsic
motivation into the expectation-confirmation model for mobile fitness
application usage. Keywords: Expectation-confirmation; Satisfaction; Perceived usefulness; Perceived

| Developing a Context Model of Process Variants for Business Process Integration | | BIBAK | Full-Text | 458-468 | |
| Jorge E. Giraldo; Demetrio A. Ovalle; Flavia M. Santoro | |||
| Since the integration of business process variants can be affected by
contextual information the aim of this paper is to propose the development of a
context model for Business Process Integration that considers the propagation
of process changes towards process variants of the reference model. The method
used to develop such a model focuses on following stages: (1) conceptualization
of process variants, by building a related ontology, (2) identification of
contextual elements, (3) definition of operational and organizational
constraints; (4) formalization of contextual situations in the variants, and
(5) construction of a reasoning mechanism for searching and retrieval of
process variants. In order to validate the context model proposed we
implemented both a prototype and a case study that consider each of the five
stages proposed. The obtained results demonstrate the effectiveness of using
this kind of approaches for business process integration. Keywords: HCI in business; Context process model; Business process integration | |||
| Designing Enterprise System Information Architecture Using Task Data | | BIBAK | Full-Text | 469-480 | |
| Dawei Huang | |||
| Much of today's information architecture for enterprise tools is organized
in a complex and feature oriented way -- frustrating the users and requiring
tons of learning to be efficient. We introduced a task taxonomy research
project that studied a few hundred database users to understand their
responsibilities, roles, and tasks. We created a task taxonomy model filled
with large quantitative data on tasks. We found task hierarchy emerged from the
model and it had a strong relationship with user roles -- implying role-based
workspace design principles. With the task hierarchy data, the degree of
relevance of task hierarchy could be estimated and applied for enterprise
information architecture designs. Keywords: Task taxonomy; Information architecture; Enterprise; Database management

| Kindle: How Gamification Can Motivate Jobseekers | | BIBAK | Full-Text | 481-492 | |
| Bart van der Kruys; Vassilis Javed Khan | |||
| Prolonged unemployment can lead to depression and a loss of self-esteem.
Gamification is a strategy that engages and motivates groups of people by
implementing game mechanics and dynamics in an existing non-gaming system. This
paper studies the possibility of using gamification to motivate job seekers. To
test the effectiveness of the ideas proposed in this paper, a between-subjects
study was executed. Those results, although preliminary, do suggest the
potential of including gamification features in job seeking systems. Keywords: Gamification in business; Jobseekers; Unemployment | |||
| Enhancing User Experience of Enterprise Systems for Improved Employee Productivity: A First Stage of Case Study | | BIBAK | Full-Text | 493-500 | |
| Honglei Li | |||
| User experience has been regarded as the focus of technology design
following the diffusion of information technology into the society level. There
are many researches discussing user experience as a concept from the software
testing and design perspective and seldom the specific dimensions of user
experience are investigated. This research attempted to conduct a case study to
explore the psychological dimensions of user experience from the interpersonal
relationship theoretical perspective. Specifically, a case study on the usage
of SAP ERP system has been conducted and 8 enterprise systems users have been
interviewed to reflect on their interactions with the ERP system. The
interpersonal relationship features is reported missing from the current
enterprise systems design. Implications to both researchers and practitioners
are provided. Keywords: User experience; Interpersonal relationship; Case study; Enterprise systems | |||
| Designing Mobile Applications for Organizational Routines | | BIBAK | Full-Text | 501-512 | |
| Kenny Lienhard; Thomas Boillat; Christine Legner | |||
| As tablet computers and smartphones have become widespread, organizations
are increasingly using mobile applications for supporting routines, i.e.,
repetitive patterns of activity that occur throughout an organization. However,
prior studies see user interactions mostly as a silo -- able to help individual
users perform better -- but not embedded in an organizational context of a user
group or company. In order to address this gap, the paper at hand looks into
the roles of mobile applications in supporting routines, and the related
principles for mobile application design. We present two mobile applications
that support domain experts in two diverse contexts, automotive car dealerships
and hospitals. Based on their analysis, we were able to identify patterns as
well as a number of design principles for mobile applications supporting
organizational routines. Keywords: Mobile application design; Organizational routines; User interface;

| Infusing User Experience into the Organizational DNA of an Enterprise IT Shop | | BIBAK | Full-Text | 513-524 | |
| Faith McCreary; Marla Gomez; Derrick Schloss | |||
| This case study describes how an enterprise IT user experience (UX) group
evolved from its genesis as a tactical, backend fixer of usability issues to a
strategic partner within a large IT department. We share specifics as to how UX
emerged as a skillset, how UX professionals evolved their methods to increase
their effectiveness, and how operational changes facilitated the adoption of UX
practices within the corporate IT shop. We detail how data-driven UX
decision-making was essential in transforming the traditional IT shop into a
more user experience driven organization that better understands their target
workforce and uses this understanding to set product strategy for the
organization and drive strategic improvement of IT solutions. Learnings and
insights from this journey provides guidance to others wanting to maximize the
value of enterprise UX investments. Keywords: User experience; Enterprise IT; UX decision-making; Big data; Thick data; UX

| Game design elements are major factors in gamification. In this study, we
seek to examine the impact of game design elements on users' in-game purchases
of virtual goods. The purchase of virtual goods due to players' intrinsic
motivation has been studied but little is known about the purchase of virtual
goods due to the use of game design elements (i.e., Points, Leaderboards and
Badges) built into the games. Extending our knowledge to this realm can help
researchers to better understand gamers' behaviors, and game designers and
marketers to better promote and sell virtual goods in online games. Keywords: Virtual goods; Gamification; Points; Leaderboards; Badges; Game design

| Teleworkers and Their Use of an Enterprise Social Networking Platform | | BIBAK | Full-Text | 532-541 | |
| Daniel Weiss; Laurie E. Damianos; Stan Drozdetski | |||
| This study surveyed teleworker usage of a social networking platform within
an enterprise. Compared to on-campus employees, teleworkers exhibited earlier
adoption, higher percentage of contributions, more variance in work hours, and
lower membership in socially-oriented groups (versus work focused groups). The
last result seems counterintuitive, and we propose two possible reasons for
this phenomenon: the perceived need to cultivate an external perception of
productivity, and lack of access to social events tied to specific geographic
office locations. In addition, we provide insights, gleaned from interviews,
into teleworker use of collaboration tools. Keywords: Telework; Remote work; Social networking; Social software; Virtual teams;

| Element Prioritization for Online Service Identity Management | | BIBAK | Full-Text | 542-549 | |
| Hoon Sik Yoo; Young Hwan Pan; Ping Shui; Da Young Ju | |||
| Services have taken the center stage over products in the industrial world.
Thus, there have been many studies that focused on how to define and utilize
service identity. The purpose of this study is to discover the elements of
service identity that need to be managed with top priority when corporations
manage their respective service identity. To discover the elements thereof and
assess priorities, this study structured service identity based on the
conventional theories. This study defined the specific elements of service
identity through expert FGI. Also, this study deducted the priorities as the 14
experts of UI/UX/service design conducted AHP evaluation as to the elements
thereof. As a result, this study found that those visual elements such as
color, icon and layout had the highest priority. This study also found that the
importance of the functional elements was relatively lower, whereas the
operational elements had the lowest priority. Keywords: Service identity; Identity management; Element prioritization; User

| Gamification and Persuasion of HP IT Service Management to Improve Performance and Engagement | | BIBAK | Full-Text | 550-562 | |
| Yue Yuan; Ke Ke Qi; Aaron Marcus | |||
| Currently, IT service management groups in many different companies are
facing a common challenge: how to motivate IT service desks to perform more
effectively and productively in order to reach desired customer service
objectives/goals and promote customer satisfactions. Undoubtedly, IT service
desks' performance and engagement will directly influence the delivered
service, and the quality of the service will either enhance or degrade customer
loyalty to a company's brand and business. Accordingly, we present an effective
and feasible way to incorporate gamification and persuasion as the incentive
mechanism into the current product, to socially reward IT service desks for
their performances, and thereby to increase their motivation to contribute and
to improve their performance. Keywords: Business; Design; Enterprise software; IT service management; Gamification;

| Low Ambiguity First Algorithm: A New Approach to Knowledge-Based Word Sense Disambiguation | | BIBAK | Full-Text | 565-574 | |
| Dongjin Choi; Myunggwon Hwang; Byeongkyu Ko; Sicheon You; Pankoo Kim | |||
| The Word Sense Disambiguation (WSD) problem has been considered as one of
the most important challenging task in Natural Language Processing (NLP)
research area. Even though, many of scientists applied the robust machine
learning, statistical techniques, and structural pattern matching approach, the
performance of WSD is still not able to bit human results due to the complexity
of human language. In order to overcome this limitation, currently, the
knowledge base such as WordNet has gained high popularity among researchers due
to the fact that this knowledge base can extensively provide not only the
definitions of nouns and verbs, but also the semantic networks between senses
which were defined by linguists. However, knowledge bases are not fully dealing
with entire words of human languages because maintaining and expanding the
knowledge base is huge task which requires many efforts and time. Expanding
knowledge base is not a big issue to concern however, a new approach is the
major goal of this paper to solve WSD problem only based on limited knowledge
resources. In this paper, we propose a method, named low ambiguity first (LAF)
algorithm, which disambiguates a polysemous word with a low ambiguity degree
first with given disambiguated words, based on the structural semantic
interconnections (SSI) approach. The LAF algorithm is based on the two
hypotheses that first, adjacent words are semantically relevant than other
words far way. Second, word ambiguity can be measured by frequency differences
between synsets of the given word in WordNet. We have proved these hypotheses
in the experiment results, the LAF algorithm can improve the performance of
traditional WSD results. Keywords: Word sense disambiguation; Natural language processing; WordNet; Low

| A Data Visualization System for Considering Relationships Among Scientific Data | | BIBAK | Full-Text | 575-584 | |
| Jangwon Gim; Yunji Jang; Yeonghun Chae; Hanmin Jung; Do-Heon Jeong | |||
| With the recent explosive increase in the amount of web-based scientific
data in big data environments, various researcher support systems have been
developed to help discover desired scientific data and search insights.
Scientific and researcher-related data are also applied to social networking
services, thus promoting inter-researcher networking. However, much time and
effort is put into big data mining to extract information customized to
researchers' specific needs. Moreover, systems that facilitate information
extraction by schematizing various inter-data relationships are absent. In this
paper, we propose a system that facilitates relevant information extraction
from scientific data and provides intuitive data visualization. Such data
visualization allows efficient relationship expression between scientific data
(relationships between researchers, acronyms and technical terms, and synonyms
of a technology name), and provides an author disambiguation interface for
authors with the same name. As a result, researchers can extract relevant
information from big data with scientific data, and obtain significant
information based on cleansed and disambiguated data. Keywords: Visualization system; Scientific data; SOLR; Implicit relationships | |||

| As the amount and the type of data for business decision making are rapidly
increasing, the importance of big data analytics is gradually critical for
making effective business strategy. However, big data analytics based decision
making systems basically requires distributed parallel computing capability in
order to make timely business strategy recommendation via processing huge
amount unstructured as well as structured business data. We introduce a big
data analytics system for automatic marketing scenario planning based on big
data platform software such as Hadoop and HBase. The analytics methodology for
scenario planning is based on prescriptive analytics which is the most advance
methodology consisting of generation of business scenarios and their
optimization, among the three analytics of descriptive, predictive, and
prescriptive analytics. Additionally, we developed a prototype of marketing
scenario planning system and its graphical user interface, as well as the
system architecture based on Hadoop eco-system based distributed parallel
computing platform. Keywords: Business intelligence; Prescriptive analytics; Big data; Marketing scenario;

| Antibiotic resistant infections are a serious threat for public health.
Hospitals are accountable for preventing the infection transmission among
patients. Situation awareness interface may improve healthcare workers'
awareness about daily aberrations in infection burden and risks associated with
infection transmission and underuse of preventive interventions. This study
attempted to apply the rules for image contraction to furnish large amount of
the electronic health record epidemiological data into a single image that
would reduce informational overload and increase infection prevention
situational awareness in a distributed group of healthcare workers. This
research postulated that contextualization of the infection prevention data may
provide critical cues for decision-making and detecting situations when
prevalence and variety of antibiotic-resistant carriers reach dangerous
thresholds. Keywords: Image construction; Situation awareness system design; Information

| Design on the BPEL Engine Generator for Adding New Functions | | BIBAK | Full-Text | 605-612 | |
| Donggyu Kwak; Jongsun Choi; Jaeyoung Choi; Hoon Ko | |||
| Business Process Execution Language (BPEL) is widely using in various
domains because it describes the flow of works depending on their conditions,
rules and the call of Web services in service-oriented computing environment,
and many experts have been studying the BPEL to use, but still the high cost is
required in existing systems. Also, the systems can only add a single function,
and it is difficult to design and add new functions as necessary. To overcome
this problem, it suggests the new function (?) to be low cost BPEL engine
generator by defining XAS4B document that can extend the grammar function of
BPEL through XML schema in order to add new functions as necessary and by
processing the document. However, new functions, which cannot be found in BPEL
grammar, are required in a specific domain. When a new function, which does not
exist in the existing language, is required, the domain-specific language
should be newly defined and developed in general. One more advantage of the
proposed system is able to add new functions without modifying BPEL engine by
AspectJ. Keywords: Environmental impact assessment; Landscape visual impact assessment;

| A Dynamic Weighted Majority Algorithm for Dynamic Data Relationships Concept Drift Detection | | BIBAK | Full-Text | 613-622 | |
| Szu-Yin Lin; Chun-Hsian Lin | |||
| In a dynamic environment, the data are changed almost instantly. It is
difficult and time-consuming to find the correlation between data. At the same
time, the concept drift might happen along with data change in the dynamic
environment. In order to stimulate the highly correlated data to support better
prediction and detected the concept drift, this study proposes a distributed
dynamic data driven Application system (DDDAS)-based dynamic weighted majority
(DWM) algorithm to solve the issue. The proposed algorithm tries to find the
correlations between data by DWM. Moreover, it is capable of detecting concept
drift. The simulation result shows the DDDAS-based DWM algorithm has up to 89%
accuracy in simulation case, and able to find the concept drift. Keywords: Dynamic weight majority; Dynamic data driven application system; Concept

intelligent user interfaces. I focus on advice-giving systems that provide
recommendations to end-users on how to solve problems, or help end-users make
the right decisions. By explanatory power I am referring to the ability of a
system to "explain" its own actions. One approach to endowing a system with
explanatory power is to develop some kind of diagram -- a graphical model that
shows how something works or makes something easier to understand. I explore,
in particular, "dynamic" diagrams in which the end user can explore the
diagrammatic structures in a variety of ways to aid in understanding and

| Breast cancer is the second leading cause of death among the women aged
between 40 and 59 in the world. The diagnosis of such disease has been a
challenging research problem. With the advancement of artificial intelligence
in medical science, numerous AI based breast cancer diagnosis system have been
proposed. Many researches combine different algorithms to develop hybrid
systems to improve the diagnosis accuracy. In this study, we propose three
artificial neural network based hybrid diagnosis systems respectively combining
association rule, correlation and genetic algorithm. The effectiveness of these
systems is examined on Wisconsin Breast Cancer Dataset. We then compare the
accuracy of these three hybrid diagnosis systems. The results indicated that
the neural network combining with association rule not only has excellent
dimensionality reduction ability but also has the similar accurate prediction
with correlation based neural network which has best accurate prediction rate
among all three systems compared. Keywords: Neural network; Association rule; Genetic algorithm; Medical artificial

| I-Chin Wu; Tzu-Li Chen; Yen-Yi Feng; Ya-Ling Cheng; Yung-Chih Chuang | |||
| Hospital Emergency Department (ED) crowding has led to an increase in
patients' waiting times; thus, solving this problem requires a better
understanding of a hospital's patient flow and the behaviors of patients.
Existing research on ED crowding is sparse and has tended to focus on the
present crowding state. Recent studies have addressed the importance of
analyzing the length of stay (LOS) to understand the behaviors of patients in
the ED. In this research, we proposed a rule-based data-mining approach to
investigate the relationship between various types of patient behaviors and
their LOS, and to build a model to predict patient LOS. The objective of this
study is to build an interactive decision support system (DSS) for Mackay
Memorial Hospital, which has the second-largest ED in Taiwan and is a
representative institute. Accordingly, the aim of this study is twofold (1)
building the DSS based on the proposed medical data-mining process in the ED
and (2) visualizing the extracting rules and the statistical data in the
proposed rule-based medical decision support (R-MDS) visualization portal. We
introduce the system framework with associated modules in this study. We aim to
integrate domain knowledge of the hospital ED with the data-mining technique to
develop the system and provide interactive DSS using modern visualization
techniques. We also believed that the qualified rules can be validated
effectively and efficiently by experts with the aid of the proposed system. Keywords: Data mining; Decision support; ED crowding; Length of stay; Rule-based | |||

| Hassan Aldarbesti; Lazaros Goutas; Juliana Sutanto | |||
| As organizational life is becoming increasingly dependent on information
systems (IS), proper IS implementation has become imperative. If it is not
properly implemented, it may disrupt the organizations' daily operations and
strategic decision-making, which can carry significant monetary consequences.
Sometimes IS implementation is halted halfway, or at any stage of the
implementation process, which may also carry significant monetary consequences
to the organizations, especially when the size of the IS implementation
projects is large. This paper focuses on the latter. Through our literature
review, we discovered that it is the human aspect, instead of the technology
aspect, that contributes to most of the failed IS implementations. To better
understand how this could take place, our study highlights two possible reasons
of failed IS implementation: (1) organizational culture complexity and (2)
power and politics in the organization. Keywords: IS implementation failure; Power; Politics; Organizational culture

| The transition to a knowledge-based economy has placed expertise and
innovation rather than physical resources as the assets driving economic growth
and international competitiveness [1]. The result is a relentless pursuit by
businesses to innovate as a means to gain competitive advantage in their
industry. However, with shorter product lifecycles, increasing product
complexity and rising research and development costs, even large firms are
struggling to develop new products on their own. Whereas there is a strong
demand from businesses to obtain external research and development resources
[2], academic institutions represent a large body of knowledge that often sees
no practical implementations. This paper discusses the integration practices in
new product development on the case study of The Smart Steering Wheel Cover
design. A research team from Delft University of Technology collaborated with a
mobile solution firm, MOBGEN, to design a system to enhance the safety and
fuel-efficiency of drivers. Analyzing the risks and benefits, challenges and
opportunities in industrial-academic collaborative projects, recommendations
are presented on optimal collaborative practices in the field of human computer
interaction. Keywords: Industry-academia collaboration; Human-computer interaction; Automotive

| Investments on information stems (IS) are costly. After the initial adoption
of Information Systems, the value of IS to an organization depends on
employees' innovative use of various features of IS in the infusion stage.
Innovative use of IS, a key activity of technology infusion, depends not only
on individual effort, but also on group effort of teams. Grounded on the
research of individual-collective process, this paper seeks to build a
situational contingency model of how individual innovative use of IS affects
group innovative use. Keywords: Individual innovative use; Group innovative use; Innovativeness diversity;

| Ambient and Aesthetic Intelligence for High-End Hospitality | | BIBAK | Full-Text | 739-747 | |
| Daniela Alina Plewe; Rui An Ong; Carsten Röcker | |||
| The core value proposition for most hospitality brands is to provide unique
customer experiences; therefore we expect commercially viable opportunities for
ambient intelligence systems in hospitality in general, and the high-end sector
in particular. We believe that ambient intelligence systems paired with
principles of Aesthetic Intelligence could facilitate such unique experiences
and at the same time strengthen and differentiate the brands. This paper gives
an overview of challenges in this field, reviews research and outlines future
scenarios enhancing safety, economic optimisation and -- especially --
convenience for hotel guests. Keywords: Smart hospitality; Business applications for home/leisure; Technology and
branding; Smart environments; Personalized services; Aesthetic intelligence;

| Vision 2020: The Future of Software Quality Management and Impacts on Global User Acceptance | | BIBAK | Full-Text | 748-760 | |
| Robin Poston; Ashley Calvert | |||
| This paper explores the future evolution of software quality management
(SQM), testing, and global user acceptance approaches keeping in mind the
evolution in software and technology quality management in general, including
new technologies and the increasing adoption of new software development life
cycle methodologies such as Agile and Scaled Agile. These evolutions are
forcing quality organizations to change the way they approach software quality
processes, including increased outsourcing of development, and the need to
update traditional testing and user acceptance testing approaches which lag
behind with manual and invasive techniques. User acceptance as we know it today
must evolve.
This discussion about evolution should deemphasize the role of the end user in "testing" and emphasize the end user's role in acceptance, adoption, and ability to influence the quality and usability of software much further upstream in the development life cycle. User acceptance teams should increase their role in user experience, the development of usability standards, non-invasive automation techniques gathering usage data, etc. All of these mechanisms should increase the ability of the end user to influence product quality and enhance the user experience and acceptance. Perceptions of end user's participation in user acceptance events need to be transformed away from just another cycle of software testing. User acceptance should not be about testing, but about validating that the end user needs and expectations have been met. All testing and other quality processes should be completed and defects corrected before the end user is engaged in the process of "accepting" the deliverable. Thus, this effort will explore the future of SQM and its impacts on global user acceptance. We will discuss how organizations involve users throughout the development life cycle to facilitate adoption, user experience, and usability of new technologies. This discussion will be embedded in the use of futuristic new technologies and development methodologies. To explore these notions, this study gathers input from technology visionaries about best practices approaches for facilitating SQM and user acceptance throughout the development life cycle.

| Early-Stage Software Start-up Survival: the Effects of Managerial Actions on Firm Performance | | BIBAK | Full-Text | 761-771 | |
| Yunfei Shi; Dongming Xu; Iris Vessey | |||
| The emergence of software start-ups contributes to society by driving
innovation as well as by creating jobs. Research, to date, mainly concentrates
on either start-ups in general or established software firms. Little research
has been conducted directly into software start-ups. The objective of this
research is to understand how early-stage software start-ups survive. We
develop a conceptual model for explaining early-stage software start-up
survival. The conceptual model illustrates important resources, capabilities,
and managerial actions that facilitate high levels of software start-up
performance. Our research contributes theoretically to IS literature in general
by developing a theory of how software start-ups survive in the early stages
and to resource-based research specifically by explaining the actions
management takes in deploying resources and capabilities to achieve high levels
of performance. Keywords: Software start-up performance; Resources; Capabilities; Managerial actions;

| An Architecture-Oriented Design Method for Human-Computer Interaction Systems | | BIBAK | Full-Text | 772-780 | |
| Yu-Chen Yang; Yi-Ling Lin; William S. Chao | |||
| In this paper, we propose an architecture-oriented design method for
human-computer interaction systems. This design method adopts the
structure-behavior coalescence (SBC) architecture as a systems model. SBC
architecture design method starts from the preparation phase and then goes
through the creative thinking, concept, preliminary design, and detailed design
phases of SBC architecture construction. SBC architecture design method uses
six fundamental diagrams to formally design the essence of a human-computer
interaction system and its details at the same time. In the concept phase,
architecture hierarchy diagram and framework diagram are used. In the
preliminary design phase, component operation diagram and component connection
diagram are used. In the detailed design phase, structure-behavior coalescence
diagram and interaction flow diagram are used. With the above six diagrams, we
then can effectively design the structure, behavior, and information of
human-computer interaction systems; resolve uncertainties and risks caused by
those non-architecture-oriented design methods. Keywords: Architecture-Oriented design method; SBC architecture; Human-Computer
interaction system | |||
