However, little is known about the impact of RW strategy on task innovativeness, organisational performance, and employees' continuance intention to remote work post-COVID-19. Using a variant of the resource-based view and the antecedent-behaviour-consequence models, data was collected from a total of 643 employees in the United Kingdom (UK) and Ghana; and analysed using structural equation modelling (Study 1). The results showed and confirmed a positive effect of RW strategy, information systems (IS) resource availability and capabilities on employees' task innovativeness leading to improved organisational performance. Further, interviews were then conducted with 22 participants from Ghana and the UK (Study 2) to understand the reasons for the outcomes in Study 1. These provided a basis for employees' continuance intention to remote work. The need to upgrade the current levels of IS resources to support job redesign and responsive workaround in times of uncertainty is highlighted for the consideration of businesses, organisations, and policymakers.

She has undertaken applied research for the major accountancy bodies in the UK, the Financial Reporting Council and government departments. The Collis Report for the DTI (Collis 2003) contributed to the 'think small first' approach taken in UK company law and has been used as the basis for research in other jurisdictions. Her subsequent report for BERR (Collis 2008) contributed to the UK government's strategy for better regulation and reducing administrative burdens on smaller entities. In addition to her research publications, Jill has published text books on accounting and on business research methods.

As a result, several researchers have investigated the means of improving the business/IT relationship. They focus on behaviors of business and IT groups and attempt to develop change management programs as a vehicle for obtaining desired behaviors from business and IT groups in order to improve the ' relationship'. However research shows that such attempts have a low success rate in attaining an effective ' relationship'. This paper argues that the reason for this is that most researchers tend to focus on behaviors of people without an in-depth understanding of their cognition, which influences those behaviors. Consequently the paper proposes a cognitive approach and explores the application of Personal Construct Theory (PCT) to understand the ' relationship' and means to improve it.

The community both promotes this vision and investigates this hierarchy, looking at how it can be accommodated into existing frameworks. In this paper, we consider a specific domain, coordinate systems’ characterising options. While we recognise that, unsurprisingly, this domain contains a ubiquity of multi-level-types, our interest is in investigating a new and different approach to understanding them. For this we needed to develop a new framework. We devise one focussing on this case, based upon scaling down to simple compositional algorithms (called constructors) to form a new, radically simpler foundation. From the simple operations of these constructors emerges the scaled up multi-level structures of the domain. We show how the simple operations of simple constructors give rise to compositional connections that shape – and so explain – different complex hierarchies and levels, including the familiar multi-level-types and relatively unknown multi-level-tuples. The framework crystallises these connections as metaphysical grounding relations. We look at how simple differences in the shape and operation of constructors give rise to different varieties of these hierarchies and levels – and the impact this has. We also look at how the constructional approach reveals the differences between foundational constructors and derived constructors built from the foundational constructors – and show that conceptual modeling’s generalisation relations are secondary and dependent upon the more foundational instantiation relations. Based upon this, we assemble a constructional foundational ontology using the BORO Foundational Ontology as our starting point. We then use this to reveal and explain the formal levels and hierarchies that underlie the options for characterising coordinate systems.

While in some circumstances the incompetence of agency employees is identified as the cause, in other circumstances organisational failure, implicitly driven by inter-organisational distrust, is to blame for inappropriate decisions taken with regards to sharing information. Sometimes implicit policies and regulations set by policy makers are blamed, while at other times, explicit rules of confidentiality and data-protection acts are accused. During the last decades, several Local Government Authorities (LGAs) in the United Kingdom have started to employ Inter-Organisational Information Systems (IOIS) to support information sharing and networked collaboration within their departments in order to meet a diverse range of citizen needs including housing services, social care services, education services, etc. However, reaching this level of cross-agency collaboration is not easy and requires additional time and effort by individuals and agencies involved. Therefore, this paper proposes and validates a novel conceptual framework that can be used as a tool for decision-making while sharing information electronically. The framework consists of four main levels: (a) investigation and presentation of factors influencing Electronic Information Sharing (EIS) in LGAs based on external environment, organisational capacity, technology environment, EIS characteristics, and interdepartmental environment, (b) investigation and presentation of the processes that an LGA department should carry out to decide whether to share information with another department, (c) mapping of the influential factors on the participation phases, and (d) prioritisation of the factors influencing EIS in LGAs in different decision-making phases.

This paper argues that the ongoing debate around which of these paradigms is better suited to undertake IS research has created confusion amongst IS researchers, particularly between those who are relatively inexperienced (e.g. PhD researchers). Inexperienced researchers tend to place emphasis on the justification of their research approaches in the context of existing paradigms without offering a clear description of how the chosen methods and paradigms are applied in the context of their own research, a key issue to assess and understand any research output. This paper does not attempt to give any suggestions as to which research methods/paradigms should be used for IS research, but to raise the awareness that the way we currently communicate our thoughts in the research methods domain may not be very effective. We argue that an initial step to undertake this challenge could be to take a more "practical" approach by focusing on the process of thinking and planning the research activity rather than focusing on the justification of the use of one or many research methods usually "loaned" from other disciplines.

Therefore, this article aims to critically survey the existing literature in order to assess the kind of research that has been performed over the years, analyze the nature of the research contributions and establish its current state of the art by positioning, evaluating and interpreting relevant research to date that is related to ODCM. To understand and identify any gaps and research opportunities, our literature study is composed of both a systematic mapping study and a systematic review study. The mapping study aims at structuring and classifying the area that is being investigated in order to give a general overview of the research that has been performed in the field. A review study on the other hand is a more thorough and rigorous inquiry and provides recommendations based on the strength of the found evidence. Our results indicate that there are several research gaps that should be addressed and we further composed several research opportunities that are possible areas for future research.

However, as the closed-worlds of ES are opened to Internet scale data sources, there is an emerging need to better understand the semantics of such data and how they can be integrated. Foundational ontologies can help establish this understanding and therefore, there is a need to investigate how such ontologies can be applied to underpin practical ES integration solutions. This paper describes research undertaken to assess the effectiveness of such an approach through the development and application of the 4D-Semantic Extract Transform Load (4D-SETL) framework. 4D-SETL was employed to integrate a number of large scale datasets and to persist the resultant ontology within a prototype warehouse based on a graph database. The advantages of the approach included the ability to combine foundational, domain and instance level ontological objects within a single coherent system. Furthermore, the approach provided a clear means of establishing and maintaining the identity of domain objects as their constituent spatiotemporal parts unfolded over time, enabling process and static data to be combined within a single model.

Expert representatives of major foundational ontologies have been invited to discuss and compare their meta-ontological choices within the context of a common case study. The workshop is aimed at exploring the ways in which different meta- ontological choices impact conceptual modelling in information systems.

Yet, for ontologies to meet these expectations, their quality must be of a good standard. The quality of an ontology is strongly based on the design method employed. This paper addresses the design problems related to the modelling of ontologies, with specific concentration on the issues related to the quality of the conceptualisations produced. The paper aims to demonstrate the impact of the modelling paradigm adopted on the quality of ontological models and, consequently, the potential impact that such a decision can have in relation to the development of software applications. To this aim, an ontology that is conceptualised based on the Object Role Modelling (ORM) approach is re-engineered into a one modelled on the basis of the Object Paradigm (OP). Next, the two ontologies are analytically compared using the specified criteria. The conducted comparison highlights that using the OP for ontology conceptualisation can provide more expressive, reusable, objective and temporal ontologies than those conceptualised on the basis of the ORM approach.
