Geographies of responsibility

D. Massey

Abstract Issues of space, place and politics run deep. There is a long history of the entanglement of the conceptualisation of space and place with the framing of political positions. The injunction to think space relationally is a very general one and, as this collection indicates, can lead in many directions. The particular avenue to be explored in this paper concerns the relationship between identity and responsibility, and the potential geographies of both.

Pustular psoriasis flare following COVID-19 infection: a case report and literature review

Eri Ohta, Eri Ohta, Etsuko Okada et al.

Generalized pustular psoriasis (GPP) is a rare, potentially life-threatening inflammatory disease characterized by neutrophilic pustules and systemic inflammation. We report a case of severe GPP triggered by SARS-CoV-2 infection in a 46-year-old woman with a long history of psoriasis. Eleven days after recovery from COVID-19 pneumonia, she developed widespread pustules and fever. Histopathology revealed subcorneal spongiform pustules and dermal neutrophilic infiltration consistent with GPP. Systemic corticosteroids followed by etretinate and deucravacitinib achieved complete remission. A literature review identified 11 infection- and 10 vaccine-related GPP cases. Compared with vaccine-associated cases, infection-related flares showed longer latency and higher corticosteroid use. Mechanistically, both SARS-CoV-2 infection and vaccination may be associated with IL-36 axis activation, potentially via spike protein–driven, Toll-like receptor–mediated innate immune signaling. This case highlights that distinct immune kinetics may underlie infection- and vaccine-related GPP, while supporting a putative role of IL-36–driven inflammation in COVID-19–associated disease exacerbation.

A História mostra-nos que não temos de escolher o pior

José Bragança de Miranda, Carlos Camponez, José Gomes Pinto

Doutorado em Ciências da Comunicação e com a agregação em Teoria da Cultura pela Universidade Nova de Lisboa, José Bragança de Miranda, em entrevista à Biblos, reflete sobre o tema da liberdade, cruzando a Comunicação, a Filosofia, a História e a Política. Refratário às lógicas monistas do pensamento e das organizações, o atual reitor da Universidade Lusófona considera que, a ter existido, o fim da História abriu-se com as Revoluções que conduziram ao controlo do poder absoluto. Reconhecendo que o controlo desse poder não é uma conquista definitiva, José Bragança de Miranda defende, no entanto, que a História mostra que a escolha do pior não se apresenta como uma inevitabilidade para a Humanidade. Por isso, mais do que discutir conceitos como a Liberdade, considera que é importante fazer uso deles, atualizando em cada ínfimo presente o legado de muitos heróis do passado.

Developing a Change Management Framework to Enhance Operational Excellence in Law Enforcement Organizations

Ayda Mussa Yousif Abdulrahman, Rafiduraida binti Abdul Rahman

This research aims to investigate the current operational status of the Ajman Police, focusing on identifying elements and issues that affect operational excellence. Using change management models, including Kotter's 8 Step Model and the ADKAR Model, the paper critically examines the hierarchical structure of the Ajman Police, its specialist groups, and their performance indicators. The problem statement highlights the negative impact of traditional and rigid organizational structures on innovation, responsiveness, and the limitations of implementing effective public safety measures, prevention, and community policing. The research design adopted is a qualitative methodology, and a sample of senior police officers was interviewed to record their views on the issues of operation and preparedness to change. In conducting the study, Semi-structured interviews were conducted with 10 participants. Results indicate that the Ajman Police has already ventured into technological advancements and civil policing. However, there are still gaps in continuous development, innovation, and the implementation of modern change management practices. The research proposes a culturally, operationally, and technologically oriented framework for change management, specifically tailored to the context of the Ajman Police. The study makes a significant research contribution to both the practice and theory fields by providing a guideline for a change management roadmap for the Ajman Police and other similar agencies, ensuring operational excellence in fast-changing environments.

Inverse problems for a generalized fractional diffusion equation with unknown history

Jaan Janno

Inverse problems for a diffusion equation containing a generalized fractional derivative are studied. The equation holds in a time interval $(0,T)$ and it is assumed that a state $u$ (solution of diffusion equation) and a source $f$ are known for $t\in (t_0,T)$ where $t_0$ is some number in $(0,T)$. Provided that $f$ satisfies certain restrictions, it is proved that product of a kernel of the derivative with an elliptic operator as well as the history of $f$ for $t\in (0,t_0)$ are uniquely recovered. In case of less restrictions on $f$ the uniqueness of the kernel and the history of $f$ is shown. Moreover, in a case when a functional of $u$ for $t\in (t_0,T)$ is given the uniqueness of the kernel is proved under unknown history of $f$.
