Towards a multidisciplinary user-centric design framework for context-aware applications

The primary aim of this article is to review and merge theories of context within linguistics, computer science, and psychology, to propose a multidisciplinary model of context that would facilitate application developers in developing richer descriptions or scenarios of how a context-aware device may be used in various dynamic mobile settings. More specifically, the aim is to:1. Investigate different viewpoints of context within linguistics, computer science, and psychology, to develop summary condensed models for each discipline. 2. Investigate the impact of contrasting viewpoints on the usability of context-aware applications. 3. Investigate the extent to which single-discipline models can be merged and the benefits and insightfulness of a merged model for designing mobile computers. 4. Investigate the extent to which a proposed multidisciplinary modelcan be applied to specific applications of context-aware computing

Toward a multidisciplinary model of context to support context-aware computing

Capturing, defining, and modeling the essence of context are challenging, compelling, and prominent issues for interdisciplinary research and discussion. The roots of its emergence lie in the inconsistencies and ambivalent definitions across and within different research specializations (e.g., philosophy, psychology, pragmatics, linguistics, computer science, and artificial intelligence). Within the area of computer science, the advent of mobile context-aware computing has stimulated broad and contrasting interpretations due to the shift from traditional static desktop computing to heterogeneous mobile environments. This transition poses many challenging, complex, and largely unanswered research issues relating to contextual interactions and usability. To address those issues, many researchers strongly encourage a multidisciplinary approach. The primary aim of this article is to review and unify theories of context within linguistics, computer science, and psychology. Summary models within each discipline are used to propose an outline and detailed multidisciplinary model of context involving (a) the differentiation of focal and contextual aspects of the user and application's world, (b) the separation of meaningful and incidental dimensions, and (c) important user and application processes. The models provide an important foundation in which complex mobile scenarios can be conceptualized and key human and social issues can be identified. The models were then applied to different applications of context-aware computing involving user communities and mobile tourist guides. The authors' future work involves developing a user-centered multidisciplinary design framework (based on their proposed models). This will be used to design a large-scale user study investigating the usability issues of a context-aware mobile computing navigation aid for visually impaired people

The Intersection of Young Children\u27s Play Activities and Multimodal Practices for Social Purposes

This qualitative study examined how children’s play activities and multimodal practices intersected for social purposes. Mediated Discourse Analysis (Scollon, 2001) informed the theory and methodology. Four questions guided the study: 1) In what types of play do preschoolers engage? 2) What strategies do preschoolers use to navigate the social boundaries of playframes? 3) What are the various modes and resources preschoolers use to engage in playframes and how do they use them? 4) What social positionings do preschoolers take on and resist in playframes? Participants included two co-teachers and twelve of the children in their pre-kindergarten classroom. Data was collected over a five-month period using participant observations and field notes. Analysis focused on multimodal discourse that took place during free play time. Four findings emerged from the study: 1) Six types of play emerged across playframes; 2) Children used entry, invitation, sustainment, and protection strategies in their playframes; 3) Children used various modes and resources, including their bodies, props, and alphabetic print, to enact character roles and social roles; and 4) Children moved fluidly within and across insider and outsider social positionings in playframes. This study extends research focused on the social dynamics of young children’s classroom play experiences and argues for an extended conceptualization of multimodal literacy as analyzed in young children’s play

Towards a comprehensive framework for the multidisciplinary evaluation of organizational maturity on business continuity program management: a systematic literature review

Organizational dependency on Information and Communication Technology (ICT) drives the preparedness challenge to cope with business process disruptions. Business Continuity Management (BCM) encompasses effective planning to enable business functions to resume to an acceptable state of operation within a defined timeframe. This paper presents a systematic literature review that communicates the strategic guidelines to streamline the organizational processes in the BCM program, culminating in the Business Continuity Plan design, according to the organization’s maturity. The systematic literature review methodology follows the Evidence- Based Software Engineering protocol assisted by the Parsifal tool, using the EbscoHost, ScienceDirect, and Scopus databases, ranging from 2000 to February 2021. International Standards and Frameworks guide the BCM program implementation, however, there is a gap in communicating metrics and what needs to be measured in the BCM program. The major paper result is the confirmation of the identified gap, through the analysis of the studies that, according to the BCM components, report strategic guidelines to streamline the BCM program. The analysis quantifies and discusses the contribution of the studies on each BCM component to design a framework supported by metrics, that allows assessing the organization’s preparedness in each BCM component, focusing on Information Systems and ICT strategies.info:eu-repo/semantics/publishedVersio

Invention in Times of Global Challenges: A Text-Based Study of Remote Sensing and Global Public Goods

We study whether remote sensing (RS), a set of technologies with global reach and a variety of applications, can be considered instrumental to the provision of global public goods (GPG). We exploit text information from patent data and apply structural topic modeling to identify topics related (or relevant) to GPG provision, and trace their participation in the evolution of remote sensing technology over time. We develop a new indicator of affinity to GPG (and other themes) using meta information from our dataset. We find that, first, RS displays features of a general-purpose technology. Second, while peripheral, GPG-relevant topics are present in the RS topic space, and in some cases overlap with topics with high affinity in AI and participation of public sector actors in invention. With our analysis, we contribute to a better understanding of the interplay between the dynamics of technology and (global) political economy, a field of research yet under-explored

Investigating the link between ICT intervention and human development using the capability approach: A case study of the computerised electricity management system

This thesis was submitted for the degree of Doctor of Philosophy and was awarded by Brunel UniversityThere has been an increasing amount of investment in Information and Communication Technologies for Development (ICT4D) interventions in developing countries under the premise of accelerating the process of social, economic and political development. These interventions are usually driven by the symbolic power of ICTs which signify progress and upon which the governments of developing countries try to draw to modernise the functioning of the state and to further enhance public service delivery to citizens. However, in this thesis it is argued that the actions and events that lead to the design and implementation of ICT4D tend to be politically motivated because ICT4D are simply interventions used by powerful actors and institutions to achieve their goals. These powerful actors include international donor agencies, politicians, top bureaucrats and private entities. In addition, it is argued that, due to these politically motivated agendas, ICT4D projects tend to be implemented in a top-down fashion and within an economic development perspective that appears to isolate the concerns of the country itself and the wellbeing of its citizens. In an attempt to try and redress social exclusion and imbalance, the capability approach drawn from the work of Amartya Sen (1999) stresses the enhancement of human capabilities and the moral aspects of development. Theoretically, the study is based on the key concepts of Sen’s Capability Approach. However, Lukes’s (1974) concepts of power are also drawn upon to address the limitation of the capability approach in addressing the concept of power. The research questions guiding this thesis are as follows: (1) How do the underlying motivations of different actors drive the design and implementation of ICT4D initiatives in developing countries? (2) How can researchers usefully conceptualise the relationship between ICT and development given the complexities in which ICT4D initiatives are undertaken? What conceptual framework could help theorise the complex relationship between ICT and development? Epistemologically, the study was conducted by following an interpretive research approach. The research was carried out in two states of Nigeria, Abuja and Plateau, and took place during the period of 2010-2011. The case-study centres on the initiation and implementation of the Computerised Electricity Management System (CEMS). Empirically, data collection techniques include 65 individual interviews, field observations and document analysis. The following are key findings of this thesis: ICT4D interventions are a complex process shaped at two levels. At the international level, they are shaped by donor agendas such as privatisation, and at the national or local level they are shaped by political and private interests. These agendas and interest are driven by powerful actors such as international donor agencies that often impose such interventions as a condition of aid, politicians who often use such interventions as campaign tools, and other top public and private actors who often use such interventions for personal gain. Hence, the beneficiaries of these projects usually have no say in the design of ICT4D projects but are rather forced to accept these interventions. Corruption is a major obstacle that hinders the expected ICT4D contributions in terms of individual opportunities and freedoms of living better lives inscribed in ICT4D interventions. Corruption exists as a “network” involving different actors present at three levels of ICT4D projects, namely the design, implementation and usage stages. Viewed from this perspective, the findings of this study show that international donor agencies, politicians, public bureaucrats and private entities are equally responsible for promoting corrupt practices in the context of ICT4D interventions. Theoretically, this thesis progresses the operationalisation of the capability approach (CA) by encapsulating the central aspect of the approach and Lukes’s (1974) concept of power. This is an innovative way of operationalising the capability approach by addressing its limitations in explaining the notion of power; the study thereby contributes to the field of IS using the capability approach and expanding the scope of theoretical analysis of contemporary ICT4D studies. Practically, to make the relationship between ICT and development more effective in meeting broader development goals, it is necessary for government policies to move beyond the mere provision of technology to also concentrate on the cultural, institutional, social and political aspects in ensuring the effective use of ICT resources, which should serve to improve people’s opportunity to participate more in social, political and economic activities

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
