Once introduced and conceptualized as a factor that causes erosion and decay of social institutions and subsequent deinstitutionalization, the notion of entropy is at odds with predictions of institutional isomorphism and seems to directly contradict the tendency toward ever-increasing institutionalization. The purpose of this paper is to offer a resolution of this theoretical inconsistency by revisiting the meaning of entropy and reconceptualizing institutionalization from an information-theoretic point of view.

It is a theoretical paper that offers an information perspective on institutionalization.

A mistaken understanding of the nature and role of entropy in the institutional theory is caused by conceptualizing it as a force that counteracts institutional tendencies and acts in opposite direction. Once institutionalization and homogeneity are seen as a product of natural tendencies in the organizational field, the role of entropy becomes clear. Entropy manifests itself at the level of information processing and corresponds with increasing uncertainty and the decrease of the value of information. Institutionalization thus can be seen as a special case of an increase in entropy and a decrease of knowledge. Institutionalization is a state of maximum entropy.

It is explained why institutionalization and institutional persistence are what to be expected in the long run and why information entropy contributes to this tendency. Contrary to the tenets of the institutional work perspective, no intentional efforts of individuals and collective actors are needed to maintain institutions. In this respect, the paper contributes to the view of institutional theory as a theory of self-organization.

In order to mitigate the effects of climate change, the UK government has set a target of achieving net zero greenhouse gas (GHG) emissions by 2050. Agricultural GHG emissions in 2017 were 45.6 million tonnes of carbon dioxide equivalent (CO₂e; 10% of UK total GHG emissions). Farmland hedgerows are a carbon sink, storing carbon in the vegetation and soils beneath them, and thus increasing hedgerow length by 40% has been proposed in the UK to help meet net zero targets. However, the full impact of this expansion on farm biodiversity is yet to be evaluated in a net zero context. This paper critically synthesises the literature on the biodiversity implications of hedgerow planting and management on arable farms in the UK as a rapid review with policy recommendations. Eight peer-reviewed articles were reviewed, with the overall scientific evidence suggesting a positive influence of hedgerow management on farmland biodiversity, particularly coppicing and hedgelaying, although other boundary features, e.g. field margins and green lanes, may be additive to net zero hedgerow policy as they often supported higher abundances and richness of species. Only one paper found hedgerow age effects on biodiversity, with no significant effects found. Key policy implications are that further research is required, particularly on the effect of hedgerow age on biodiversity, as well as mammalian and avian responses to hedgerow planting and management, in order to fully evaluate hedgerow expansion impacts on biodiversity.

This qualitative study set within Northern Ireland aims to explore professional perspectives on the application of evidence-informed practice to the adult safeguarding threshold screening process.

Data was gathered from seven social workers in one health and social care trust area, who perform the designated adult protection role, through individual semi-structured interviews in one region of Northern Ireland. The interview schedule comprised of a series of questions examining the role of the designated adult protection officer and included three vignettes (Appendix). A thematic analysis was undertaken using NVIVO software.

This paper reports main findings under the themes of: the role of the designated adult protection officer, threshold decision-making, evidence-informed practice and service improvement. One of the main findings was that professionals viewed the current process as too bureaucratic, and there was a desire to engage in more preventive safeguarding in collaboration with service users. There was a need to promote awareness of evidence-informed practice as it applies to the threshold screening process. Furthermore, the study raised the question of the need to consider the application of models or methods of assessment to the threshold screening process.

This in-depth exploration of the role of designated adult protection officers in Northern Ireland provides a valuable insight into the complexity involved in managing adult safeguarding referrals and investigations. This study adds to the existing knowledge base, identifies potential service improvements and highlights the gap in evidence-based practice as it applies to the threshold screening process. Threshold screening of adult safeguarding referrals remains a subjective process and is open to interpretation and differences in professional judgement. The study highlights the need to consider the application of quality improvement methodology to the threshold screening assessment and the need to promote the exchange of safeguarding knowledge.
