Abstract

Purpose

The design, construction and deployment of a large virtual campus are a complex issue. Present virtual campuses are made of several software applications that complement e‐learning platforms. In order to develop and maintain such virtual campuses, a complex software engineering infrastructure is needed. This paper aims to analyse the software engineering infrastructure in the virtual campus deployed at the Universidad Complutense de Madrid.

Design/methodology/approach

The software engineering infrastructure is analysed from three perspectives: process model; programming language and computer‐aided software engineering tools and design patterns and architecture.

Findings

Software engineering infrastructure is a key issue in virtual campuses.

Originality/value

The value of the paper is to make our experience available to a wider audience so that organisations interested in the deployment of a large virtual campus can take advantage of our work.

Abstract

Purpose

The paper proposes the development of a graphical architecture description language (ADL) that allows a better understanding of software architectures for nontechnical actors and purposes and, beyond, can serve as a communication tool between domain experts and IT experts, for instance, in a software development process.

Design/methodology/approach

The paper follows the methods and guidelines of design science research. By deriving characteristics and general requirements for ADLs from a research literature review and from industry standards, the paper provides a conceptual modeling approach for an ADL. The model design is based on typical requirements and suggestions derived from literature and related work. The application possibilities and advantages are then demonstrated with a usage scenario.

Findings

The paper elaborates a user-oriented ADL that makes software architecture comprehensible for stakeholders and end users. It provides a high level of abstraction and, thus, is not restricted to a particular domain. The paper also provides a corresponding modeling editor as well as an underlying catalogue with symbols and rules for the ADL.

Research limitations/implications

As this is a conceptual study, the ADL has not been practically evaluated yet. Thus, the usefulness of this academic approach for the industry remains to be validated.

Originality/value

The elaborated ADL can serve as a language to visualize software architectures, particularly in the business domain, in a comprehensible manner. Still, it retains the structured character of ADLs to facilitate communication on an IT-near level. In including nontechnical actors, the approach broadens the overall application capabilities of ADLs.

Abstract

Purpose

Energy is the major concern in wireless sensor networks (WSNs) for most of the applications. There exist many factors for higher energy consumption in WSNs. The purpose of this work is to increase the coverage area maintaining the minimum possible nodes or sensors.

Design/methodology/approach

This paper has proposed multilayer (ML) nodes deployment with distributed MAC (DS-MAC) in which nodes listen time is controlled based on communication of neighbors. Game theory optimization helps in addressing path loss constraints while selecting path toward base stations (BS).

Findings

The simulation is carried out using NS-2.35, and it shows better performance in ML DS-MAC compared to random topology in DS-MAC with same number of BS. The proposed method improves performance of network in terms of energy consumption, network lifetime and better throughput.

Research limitations/implications

Energy consumption is the major problem in WSNs and for which there exist many reasons, and many approaches are being proposed by researchers based on application in which WSN is used. Node mobility, topology, multitier and ML deployment and path loss constraints are some of the concerns in WSNs.

Practical implications

Game theory is used in different situations like countries whose army race, business firms that are competing, animals generally fighting for prey, political parties competing for vote, penalty kicks for the players in football and so on.

Social implications

WSNs find applications in surveillance, monitoring, inspections for wild life, sea life, underground pipes and so on.

Originality/value

Game theory optimization helps in addressing path loss constraints while selecting path toward BS.

Abstract

Purpose

The near‐collapse of the world's financial system in 2008 brought into focus significant limitations in the data and analysis tools available to mitigate potential risks across the financial system. It has raised calls to provide comprehensive data and adequate tools to identify and relieve systemic risk. In this paper, an infrastructure is proposed to address the need for a new information system in systemic regulation.

Design/methodology/approach

The proposed infrastructure is developed using the Fed's Bank Holding Company Supervision Manual as a guideline. The model uses a data fusion approach that allows integration of inspection data, external data, and other regulatory data of different granularity. A proprietary application known as Decision Making Toolbox (DMT) is being developed with three‐tier architecture.

Findings

The integrated all‐in‐one approach will enhance the efficiency, scope, and quality of studies applied to systemic regulation and will facilitate easy decision making for effective regulation.

Originality/value

This concept integrates data and measures that are needed for systemic regulation. It facilitates easy decision making, by regulators with an integrated all‐in‐one information infrastructure, for effective regulation.

Abstract

Purpose

This paper has proposed a Fog architecture-based framework, which classifies dengue patients into uninfected, infected and severely infected using a data set built in 2010. The aim of this proposed framework is to developed a latency-aware system for classifying users into different categories based on their respective symptoms using Internet of Things (IoT) sensors and audio and video files.

Design/methodology/approach

To achieve the aforesaid aim, a smart framework is proposed, which consist of three components, namely, IoT layer, Fog infrastructure and cloud computing. The latency of the system is reduced by using network devices located in the Fog infrastructure. Data generated by IoT layer will first be processed by Fog layer devices which are in closer proximity of the user. Raw data and data generated will later be stored on cloud infrastructure, from where it will be sent to different entities such as user, hospital, doctor and government healthcare agencies.

Findings

Experimental evaluation proved the hypothesis that using the Fog infrastructure can achieve better response time for latency sensitive applications with the least effect on accuracy of the system.

Originality/value

The proposed Fog-based architecture can be used with IoT to directly link it with the Fog layer.

Abstract

Purpose

In socio-technical transition theory, resistance by existing technology and regime resistance plays a key role. The resistance is in the form of intentional improvements; eventually, the regime destabilizes and adopts the new technology, referred to as the sailing-ship effect. Researchers used a structural view and examined it as a strategic action and its relationship with new technology (competitive/symbiotic) in non-fast-changing sailing systems. This study uses a microlevel view and examines it in a fast-changing where products/services are developed by integrating existing technology with new product innovations; their success depends on addressing technical/market uncertainty. This study examines the sailing-ship effect in a fast-changing system and contributes to the socio-technical transition theory.

Design/methodology/approach

The authors need to examine the phenomena of the sailing-ship effect in its setting, and a case-study method is appropriate. The selected case provided diverse analytic and heuristic perspectives to examine the phenomena; therefore, it was a single case study.

Findings

In an IT scenario, the strategic actions decide and realize agility and competitive advantage by formulating appropriate goals with required budgets and coevolutionary changes to resources at product, process and organizational levels, addressing technical/market uncertainty. Moreover, the agility displayed by strategic actions determines the relationship with new technology, which is interspersed. Finally, it provided insights into struggle, navigation and negotiations, forming strategic actions to display the sailing-ship effect.

Research limitations/implications

The study selected a Banking Financial Services and Insurance product of an IT Services company. As start-ups exhibit inherent (emergent) agility, the authors can examine agility as a combination of emergent and strategic actions by selecting a start-up.

Practical implications

The study highlights the strategic actions specific to an IT services company. It developed its product and services by steering clear from IT innovations such as native cloud and continuous deployment. It improved its products/services with necessary organizational changes and achieved the desired agility and competitive advantage. Therefore, organizations devise appropriate strategic actions to combat the sailing-ship effect apart from setting goals and selecting IT innovations.

Originality/value

The study expands the socio-technical transition theory by selecting a fast-changing system. It provided insights into the relationship between existing and new technology and the strategic actions necessary to manage technical and market uncertainty and achieve the desired competitive advantage, or the sailing-ship effect.

Abstract

Purpose

This paper aims to describe MoM-NOCS, a Framework and a System that support communities with common interests in nature to capture and share multimedia observations of nature objects or events using mobile devices.

Design/methodology/approach

The observations are automatically associated with contextual metadata that allow them to be visualized on top of 2D or 3D maps. The observations are managed by a multimedia management system, and annotated by the same and/or other users with common interests. Annotations made by the crowd support the knowledge distillation of the data and data provenance processes in the system.

Findings

MoM-NOCS is complementary and interoperable with systems that are managed by natural history museums like MMAT (Makris et al., 2013) and biodiversity metadata management systems like BIOCASE (BioCASE) and GBIF (GBIF) so that they can link to interesting observations in the system, and the statistics of the observations that they manage can be visualized by the software.

Originality/value

The Framework offers rich functionality for visualizing the observations made by the crowd as function of time.

Abstract

Purpose

Apart from, the smart edge computing (EC) robot (SECR) provides the tools to manage Internet of things (IoT) services in the edge landscape by means of real-world test-bed designed in ECR. Eventually, based on the results from two experiments held in little constrained condition, such as the maximum data size is 2GB, the performance of the proposed techniques demonstrate the effectiveness, scalability and performance efficiency of the proposed IoT model.

Design/methodology/approach

Certainly, the proposed SECR is trying primarily to take over other traditional static robots in a centralized or distributed cloud environment. One aspect of representation of the proposed edge computing algorithms is due to challenge to slow down the consumption of time which happened in an artificial intelligence (AI) robot system. Thus, the developed SECR trained by tiny machine learning (TinyML) techniques to develop a decentralized and dynamic software environment.

Findings

Specifically, the waste time of SECR has actually slowed down when it is embedded with Edge Computing devices in the demonstration of data transmission within different paths. The TinyML is applied to train with image data sets for generating a framework running in the SECR for the recognition which has also proved with a second complete experiment.

Originality/value

The work presented in this paper is the first research effort, and which is focusing on resource allocation and dynamic path selection for edge computing. The developed platform using a decoupled resource management model that manages the allocation of micro node resources independent of the service provisioning performed at the cloud and manager nodes. Besides, the algorithm of the edge computing management is established with different path and pass large data to cloud and receive it. In this work which considered the SECR framework is able to perform the same function as that supports to the multi-dimensional scaling (MDS).

Abstract

Purpose

While the literature on multitier supply chain management traditionally assumes that first-tier suppliers belong to the visible proportion of the supply base, intermediaries might limit focal firms' visible horizon already at this stage. High power asymmetries promoting centrality and complexity in the supply network are seen as a particular root cause that limits the impact of governance mechanisms for sustainability. To map the space for governance mechanisms in a network-sensitive context more comprehensively, the study analyzes supply network characteristics from a power perspective.

Design/methodology/approach

This research is conceptual. To better understand power imbalances and mutual dependencies from network centrality and complexity, network configurations were constructed drawing on resource dependence theory. These configurations allow deducing the impact of (non-)mediated governance mechanisms for a sustainable development in the supply network. An agenda to stimulate future empirical and model-based research is accordingly presented.

Findings

The research shows that those networks with densely interconnected first-tier suppliers promote network centrality and complexity, leading to an inverted U-shape relationship between the focal firm's exertion of coercive power and the sustainability performance in the supply network. The findings allow a more comprehensive theoretical grounding for mapping governance approaches in a network-sensitive context and provide insights on how to avoid negative effects from power asymmetries.

Practical implications

The findings suggest the need for accompanying, indirect governance mechanisms already at the stage of first-tier suppliers based on non-mediated forms of power, such as referent power, also promoting disintermediation. Purchasing companies may also consider using digital platform technologies that foster disintermediation, such as blockchain technology.

Originality/value

By studying intermediaries from a power and network perspective, the conceptualization adds to the discussion on governance in multitier sustainable supply chain networks in various industries. Furthermore, it contributes to the increasing efforts of middle-range theorizing in logistics and supply chain management. The results partially challenge previous assumptions on the moderating role of specific network characteristics.

Abstract

Purpose

The purpose of this paper is to examine the buyer–supplier exchange dynamic in terms of the influence of product and market contingencies on the interfirm connectivity, governance and exchange performance of interconnected dyads in multitier supply chains (MSCs).

Design/methodology/approach

Using an inductive approach, the authors analyzed the supply network of a high-end motorcycle manufacturer (OEM). Four sets of “interconnected dyads” constituting four embedded units of analysis were considered, each involving the OEM, its tier 1 and corresponding tier 2 suppliers. These interconnected dyads representing four strategic components and their sub-components offer contrasts in terms of product and market contingencies.

Findings

This analysis reveals that product and market contingencies influence patterns of dependence among firms. These in turn impact interfirm connectivity (i.e. structural characteristic), and the degree of contract formalization, collaboration and concentration of decision-making power (i.e. governance characteristics) in the interconnected dyads. The authors also found that structural and governance aspects can have mutual influence, leading to satisfactory or unsatisfactory outcomes. Propositions synthesizing the relationships among the constructs are developed.

Research limitations/implications

The constructs and their underlying relationships need to be further refined if we are to devise hypotheses and validate them at a large-scale empirical level.

Originality/value

This is one of the first studies to explore the influence of business contingencies on the complex buyer–supplier exchange dynamic in MSCs having a “beyond the dyad” perspective. The authors address why and how various types of interconnectivity are developed, and how the interplay among interfirm dependence, connectivity and governance influences the suppliers’ performance in the MSCs.
