The patterning of finance/security : a designerly walkthrough of challenger banking apps

Culture is being ‘appified’. Diverse, pre-existing everyday activities are being redesigned so they happen with and through apps. While apps are often encountered as equivalent icons in apps stores or digital devices, the processes of appification – that is, the actions required to turn something into an app – vary significantly. In this article, we offer a comparative analysis of a number of ‘challenger’ banking apps in the United Kingdom. As a retail service, banking is highly regulated and banks must take steps to identify and verify their customers before entering a retail relationship. Once established, this ‘secured’ financial identity underpins a lot of everyday economic activity. Adopting the method of the walkthrough analysis, we study the specific ways these processes of identifying and verifying the identity of the customer (now the user) occur through user onboarding. We argue that banking apps provide a unique way of binding the user to an identity, one that combines the affordances of smart phones with the techniques, knowledge and patterns of user experience design. With the appification of banking, we see new processes of security folded into the everyday experience of apps. Our analysis shows how these binding identities are achieved through what we refer to as the patterning of finance/security. This patterning is significant, moreover, given its availability for wider circulation beyond the context of retail banking apps

Accessible user interface support for multi-device ubiquitous applications: architectural modifiability considerations

The market for personal computing devices is rapidly expanding from PC, to mobile, home entertainment systems, and even the automotive industry. When developing software targeting such ubiquitous devices, the balance between development costs and market coverage has turned out to be a challenging issue. With the rise of Web technology and the Internet of things, ubiquitous applications have become a reality. Nonetheless, the diversity of presentation and interaction modalities still drastically limit the number of targetable devices and the accessibility toward end users. This paper presents webinos, a multi-device application middleware platform founded on the Future Internet infrastructure. Hereto, the platform's architectural modifiability considerations are described and evaluated as a generic enabler for supporting applications, which are executed in ubiquitous computing environments

Distribution pattern-driven development of service architectures

Distributed systems are being constructed by composing a number of discrete components. This practice is particularly prevalent within the Web service domain in the form of service process orchestration and choreography. Often, enterprise systems are built from many existing discrete applications such as legacy applications exposed using Web service interfaces. There are a number of architectural configurations or distribution patterns, which express how a composed system is to be deployed in a distributed environment. However, the amount of code required to realise these distribution patterns is considerable. In this paper, we propose a distribution pattern-driven approach to service composition and architecting. We develop, based on a catalog of patterns, a UML-compliant framework, which takes existing Web service interfaces as its input and generates executable Web service compositions based on a distribution pattern chosen by the software architect

Towards an aspect weaving BPEL engine

This position paper proposes the use of dynamic aspects and the visitor design pattern to obtain a highly configurable and extensible BPEL engine. Using these two techniques, the core of this infrastructural software can be customised to meet new requirements and add features such as debugging, execution monitoring, or changing to another Web Service selection policy. Additionally, it can easily be extended to cope with customer-specific BPEL extensions. We propose the use of dynamic aspects not only on the engine itself but also on the workflow in order to tackle the problems of Web Service hot deployment and hot fixes to long running processes. In this way, composing aWeb Service "on-the-fly" means weaving its choreography interface into the workflow

Context-driven progressive enhancement of mobile web applications: a multicriteria decision-making approach

Personal computing has become all about mobile and embedded devices. As a result, the adoption rate of smartphones is rapidly increasing and this trend has set a need for mobile applications to be available at anytime, anywhere and on any device. Despite the obvious advantages of such immersive mobile applications, software developers are increasingly facing the challenges related to device fragmentation. Current application development solutions are insufficiently prepared for handling the enormous variety of software platforms and hardware characteristics covering the mobile eco-system. As a result, maintaining a viable balance between development costs and market coverage has turned out to be a challenging issue when developing mobile applications. This article proposes a context-aware software platform for the development and delivery of self-adaptive mobile applications over the Web. An adaptive application composition approach is introduced, capable of autonomously bypassing context-related fragmentation issues. This goal is achieved by incorporating and validating the concept of fine-grained progressive application enhancements based on a multicriteria decision-making strategy

Investigation of Entrepreneurial Marketing Practices in Social Enterprises in the Context of Bangladesh

Despite the strong integration between marketing and entrepreneurship in practice and increasing attention towards social entrepreneurship (SE), marketing scholarsclaim that the current SE conceptualisation has yet satisfactorily offered a comprehensive framework for research, policy and practice adjoining its marketing phenomenon. This study thus employs entrepreneurial marketing (EM) as a theoretical framework to analyse and develop an insight into the practices used by social enterprises. As social enterprises typically seek betterment of social, environmental, and community-based initiatives and gain, the EM strategy often fits well for this venture as more unconventional means of marketing are usually required for such enterprises. In particular, this research investigates how social enterprises apply EM in Bangladesh, an emerging economy. In Bangladesh, Social Enterprises (SE) have experienced many challenges, including achieving long-term growth and remaining in business due to their unsustainable business models and lack of competitiveness in a highly competitive global market. A qualitative case study has been in this thesis adopts approach to examine the EM strategy and its practices. Data was also gathered and analysed through secondary sources such as online observation by reviewing websites, Facebook, YouTube, and different reports from case study SEs. In line with the interpretive approach, this online observation and case study method allows the researcher to gain insight into EM practices that helps the development of a new framework. Further, data was collected from interviews with the entrepreneurs and respective managers from some selected case study SEs. The researcher used a combination of purposive and snowballing sampling to determine 14 participants (entrepreneurs and managers) from seven case study SEs for in-depth interviews. Data triangulation was conducted to ensure the authenticity of data and information through in-depth interviewing of an additional five social entrepreneurs from five different SEs. By examining EM within the context of the social entrepreneurship sector, this study investigates how SEs in an emerging economy apply EM strategy. In so doing, this research examines the elements essential to an EM framework when being applied to a SE context. Furthermore, it offers a clear explanation of the interactivity of the elements. The thesis contributes to the EM literature by proposing a new EM framework for SEs, responding to the scholarly inquiry of cross-disciplinary research. A key contribution of this thesis lies in the integration of the social value creation element, an important aspect discussed in Shaw (2004) and Santos (2012), into the new EM framework and expanding this concept by introducing the empowerment dimension. In addition to the theoretical contributions, the research also offers managerial implications and suggestions for future studie

Heavy meta: model-driven domain-specific generation of generative domain-specific modeling tools

Software is so prevalent in all areas of life that one could expect we have come up with more simple and intuitive ways for its creation by now. However, software development is still too complicated to easily and efficiently cope with individual demands, customizations, and changes. Model-based approaches promise improvements through a more comprehensible layer of abstraction, but they are rarely fully embraced in practice. They are perceived as being overly complex, imposing additional work, and lacking the flexibility required in the real world. This thesis presents a novel approach to model-driven software engineering that focuses on simplicity through highly specialized tools. Domain experts are provided with development tools tailored to their individual needs, where they can easily specify the intent of the software using their known terms and concepts. This domain specificity (D) is a powerful mechanism to boil down the effort of defining a system to relevant aspects only. Many concepts are set upfront, which imposes a huge potential for automated generation. However, the full potential of domain-specific models can only unfold, if they are used as primary artifacts of development. The presented approach thus combines domain specificity with full generation (F) to achieve an overall pushbutton generation that does not require any round-trip engineering. Furthermore, service orientation (S) introduces a ‘just use’ philosophy of including arbitrarily complex functionality without needing to know their implementation, which also restores flexibility potentially sacrificed by the domain focus. The unique combination of these three DFS properties facilitates a focused, efficient, and flexible simplicity-driven way of software development. Key to the approach is a holistic solution that in particular also covers the simplicity-driven development of the required highly specialized DFS tools, as nothing would be gained if the costs of developing such tools outweighed the resulting benefits. This simplicity is achieved by applying the very same DFS concepts to the domain of tool development itself: DFS modeling tools are fully generated from models and services specialized to the (meta) domain of modeling tools. The presented Cinco meta tooling suite is a first implementation of such a meta DFS tool. It focuses on the generation of graphical modeling tools for graph structures comprising of various types of nodes and edges. Cinco has been very successfully applied to numerous industrial and academic projects, and thus also serves as a proof of concept for the DFS approach itself. The unique combination of the three DFS strategies and Cinco's meta-level approach towards their realization in practice lay the foundation for a new paradigm of software development that is strongly focused on simplicity

Tangible user interfaces : past, present and future directions

In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research

Supporting Semantically Enhanced Web Service Discovery for Enterprise Application Integration

The availability of sophisticated Web service discovery mechanisms is an essential prerequisite for increasing the levels of efficiency and automation in EAI. In this chapter, we present an approach for developing service registries building on the UDDI standard and offering semantically-enhanced publication and discovery capabilities in order to overcome some of the known limitations of conventional service registries. The approach aspires to promote efficiency in EAI in a number of ways, but primarily by automating the task of evaluating service integrability on the basis of the input and output messages that are defined in the Web service’s interface. The presented solution combines the use of three technology standards to meet its objectives: OWL-DL, for modelling service characteristics and performing fine-grained service matchmaking via DL reasoning, SAWSDL, for creating semantically annotated descriptions of service interfaces, and UDDI, for storing and retrieving syntactic and semantic information about services and service providers
