Hierarchy theory is a fundamental systems approach that offers rich perspectives in understanding the flow of matter and information between different levels of control. This paper offers an extended view of hierarchy theory, which can be used to illuminate complex organizational environments. Firstly, the characteristics of a hierarchy are explored, and the flow of information and resources, the perception of space and time and changing purposes and perspectives are explored. Secondly, the importance of networks, nodes and hubs is examined as a necessary element of understanding hierarchies. Thirdly, the properties of boundaries, which act as filters both maintaining the hierarchy and enabling effective organizations, are discussed. A context for exploring the application of extended hierarchical theory is provided in an exploration of a large‐scale information technology failure in the UK government. The failure of FIReControl, a project which was to provide a nationwide system to manage disasters and terrorist attacks, is explored using the range of extended hierarchy theory concepts. The paper offers an iterative process for applying extended hierarchy theory and calls for a greater attention in systems research to boundaries, filters and networks.

PurposeReflexivity involves critical reflection by the qualitative researcher as to the influence of the researcher's culture, history and belief on the conduct and outcome of the research. It is often seen as a practice exercised in the analysis of results in order to attempt to objectify the research. The purpose of this paper is to argue that the value of reflexivity is located in its practice in the field encounter as a means of recognising and embracing subjectivity. In order to widen reflexivity as hermeneutics, the paper draws on Gadamer's philosophical hermeneutics as developed in "Truth and Method".Design/methodology/approachThis is a conceptual paper which distils critical themes from Gadamer's truth and method and applies them to the concept of reflexivity as applied in the field.FindingsThe paper suggests that reflexivity is an important component in the field encounter. Immersion in the language and terms of the field is critical to understanding meaning; who I am, my past, my lived experience are essential inputs to my research; the researcher's opinions, ideas and outspoken statements are part of the fabric of qualitative research; qualitative interpretation as a creative exercise; qualitative research should bring insight and understanding that can be applied to catalyse change.Practical implicationsUnderstanding and applying reflexivity in the field will provide innovative insights which can be carried through to the data analysis.Originality/valueThis study uniquely applies Gadamer's philosophical hermeneutics to reflexivity and the field encounter.

Reports that there are increasing trends towards the commercialisation of public sector information. Explains the concepts of information trading and discusses the role of the public sector. Describes three case studies within the UK government. Identifies the lack of a uniform approach to information trading within UK government departments in terms of attitudes to information provision, information costing and pricing and the resourcing of an information trading function. Discusses issues concerning the national and departmental policy on information distribution and trading; the resourcing and management of information technology to support the information trading function; the development of an information‐aware culture within the government and its departments and the development of contractual relationships with marketing agents within the private sector. Examines the effect of online information provision on information trading. Discusses the application of agency theory to the study of the role of marketing agents and identifies their importance in the development of a public sector information trading market. Concludes that there is a lack of clear direction for government departments concerning information trading.

In recent years local authorities and hospitals within the UK have
been subjected to substantial change, which has resulted in an explosion
in the use of information systems (IS). IS managers, personnel and
executives within local authorities and hospitals were interviewed in
order to determine the effect of context and culture on the take‐up of
IS. Context was considered at an external and internal level. Cultural
issues were particularly important in the take‐up of IS. In both local
authorities and hospitals the IT culture clashed with the subcultures it
was supporting. Highlights three issues: the cultural decentralization
of IS, which resulted in an unplanned proliferation of disparate
systems; the over‐emphasis on operational systems by the IS function to
the detriment of management information systems; and the reinforcing of
barriers between subcultures through incompatible IS. Suggests that IS
departments within the public sector need to be proactive in their
support of subcultures and to enrol them in a common goal of the
provision of integrated IS within the organization.

The planning and implementation of electronic information systems and technology (IS/IT) following the National Health Service (NHS) reforms in the UK are both widespread and significant. Considers these new organizational arrangements, for primary care general practitioners (GPs), to aid decisions for the referral of patients to hospital specialists. The proposals, through an analyses of the concept of markets and hierarchies, may result in an alternative and better referral experience for those patients who express a preference. Presents an overview of the reforms and notes the subsequent impact of IS/IT as a facilitator for changing the structure of primary care within the NHS. Argues that, if primary care physicians adopt a more appropriate management of IS/IT and are proactive in its application, then the outcome will produce more patient choice, less non‐attendance and consequently improved health care provision.

The extensive disruption to and digital transformation of travel administration across borders largely due to COVID-19 mean that digital vaccine passports are being developed to resume international travel and kick-start the global economy. Currently, a wide range of actors are using a variety of different approaches and technologies to develop such a system. This paper considers the techno-ethical issues raised by the digital nature of vaccine passports and the application of leading-edge technologies such as blockchain in developing and deploying them. We briefly analyse four of the most advanced systems – IBM's Digital Health Passport "Common Pass," the International Air Transport Association's Travel Pass, the Linux Foundation Public Health's COVID-19 Credentials Initiative and the Vaccination Credential Initiative (Microsoft and Oracle) – and then consider the approach being taken for the EU Digital COVID Certificate. Each of these raises a range of issues, particularly relating to the General Data Protection Regulation (GDPR) and the need for standards and due diligence in the application of innovative technologies (eg blockchain) that will directly challenge policymakers when attempting to regulate within the network of networks.
