Designing mobile technology to promote sustainable food choices
This paper is an experience report based on challenges
encountered when designing scalable mobile persuasive HCI
applications to help users make informed choices over their food consumption. We recently developed Tagliatelle, a social tagging system to help users to accurately monitor and assess their dietary behaviour and to promote healthier food choices. In this paper we propose a similar system in order to help users understand the sustainability of their food choices. We discuss the challenges inherent in doing so, and extrapolate some important issues that
need to be addressed by technological developments that aim to persuade users to adopt more sustainable behaviours
The Metabolism and Growth of Web Forums
We view web forums as virtual living organisms feeding on user's attention
and investigate how these organisms grow at the expense of collective
attention. We find that the "body mass" () and "energy consumption" ()
of the studied forums exhibits the allometric growth property, i.e., . This implies that within a forum, the network transporting
attention flow between threads has a structure invariant of time, despite of
the continuously changing of the nodes (threads) and edges (clickstreams). The
observed time-invariant topology allows us to explain the dynamics of networks
by the behavior of threads. In particular, we describe the clickstream
dissipation on threads using the function , in which
is the clickstreams to node and is the clickstream dissipated
from . It turns out that , an indicator for dissipation efficiency,
is negatively correlated with and sets the lower boundary
for . Our findings have practical consequences. For example,
can be used as a measure of the "stickiness" of forums, because it quantifies
the stable ability of forums to convert into , i.e., to remain users
"lock-in" the forum. Meanwhile, the correlation between and
provides a convenient method to evaluate the `stickiness" of forums. Finally,
we discuss an optimized "body mass" of forums at around that minimizes
and maximizes .Comment: 6 figure
Semantic discovery and reuse of business process patterns
Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
Creating Value By Object Hyperlinking Along The Consumer Buying Decision Process In The IoT Era
Within the IoT scope, a new application named ‘object hyperlinking’ has evolved. Object hyperlinking is the pervasive presence of different things or objects identified by tags, sensors, and mobile phones that can interact with each other as well as with their neighbors through unique addressing schemes for business purpose. Enabled by Automatic Identification and Data Capture (AIDC) technologies such as QR code and NFC, object hyperlinking services make it possible link any object or location to a more comprehensive and editable information. While tagging technologies have good prospects to offer more opportunities in a company’s interaction with its consumers, how this capability can be best applied and what innovative business services be created with object hyperlinking remain to be discovered. This study surveys and examines 76 projects of object hyperlinking in Taiwan and provides a framework to figure out business value and issues of object hyperlinking along the five stages of a consumer buying decision process. Based on the functionality and purpose of object hyperlinking services, this framework is conducted in dimensions of value creation, value orientation, functionality, key factor and challenges, key activities within organization, and managerial issues concerned. Some innovative business models enabled by object hyperlinking will also be introduced. The research results found that only when the information gathered by identified objects is used, analyzed, and distributed into wide business activities in term of marketing, customer service and firm level strategy planning, the effectiveness and value of object hyperlinking services can be realized at its maximum. The integration across different consumer buying decision process is also important. The more applications of object hyperlinking in different buying decisions, the more benefits will be created for customers. Managers can use the list of dimensions proposed in the framework to develop rich IoT business from enhancing service operations with object hyperlinking
