Spontaneous Raman spectroscopy enables non-ionising, non-destructive, and label-free acquisition of a biochemical fingerprint for a given sample. However, the long integration times required largely prohibit high-throughput applications. Here, we present a comprehensive deep learning framework for extreme speed-up of spontaneous Raman imaging. Our deep learning framework enhances Raman imaging two-fold, effectively reconstructing both spectral and spatial information from low spatial resolution, low signal-to-noise ratio images to achieve extreme Raman imaging time speed-ups of 40-90x while mainting high reconstruction fidelity. As such, our framework could enable a host of higher-throughput spontaneous Raman spectroscopy applications across a diverse range of fields.

Supply chains can play a major role in reducing countries' safety and security threats; the role of network responsiveness offers insights into management exchanges responding to the preparedness of developed countries like Sweden. Illustrating the managing of overall supply chain capabilities among network responsiveness stems from the supply chain responsiveness concept. Several challenges to responsiveness prevent actors' networks from fully benefitting from coordination. A management approach is employed to explore the impact of network responsiveness on the supply chain as an overarching strategy for safety and security. The study suggests three different approaches which differ in their impact on the network's responsiveness: (i) an overall strategic planning approach, (ii) one integrated system approach for the overall response, and (iii) a coordination approach for managing the overall supply chain responsiveness strategy. RESUMEN. Las cadenas de suministro pueden desempeñar un rol importante en la reducción de amenazas a la seguridad y protección de países desarrollados, como Suecia. Este articulo ofrece perspectivas acerca de la cadena de suministro y deriva del concepto de preparación para emergencias. Varios desafíos impiden que las redes de actores se beneficien plenamente de la coordinación. El estudio enfoca el impacto de las redes de actores en la cadena de suministro como una estrategia general para el manejo de la seguridad. Tres enfoques difieren en su impacto en la capacidad de las redes de actores envueltos; (i) un enfoque de planificación estratégica general, (ii) un enfoque de sistema integrado para la respuesta general, (iii) un enfoque de coordinación para gestionar la estrategia general de capacidad en respuesta a la cadena de suministro.

PurposeAt the inception of the Journal of Humanitarian Logistics and Supply Chain Management (JHLSCM), logistics coordination was identified as important, both in practice and research, but few studies on the topic had been published. Ten years later, many, if not most, papers in the journal mention the topic. So the picture has changed, but to what extent? This paper discusses how coordination research has followed humanitarian logistics practice and vice versa.Design/methodology/approachThe point of departure in the present article is the most salient topic from the study’s original papers (Jahre et al., 2009; Jahre and Jensen, 2010). The authors discuss how these topics have developed in research and practice. A recent literature review (Grange et al., 2020) enables us to pick relevant papers from JHLSCM and supplement them with more recent ones. The authors complement this approach with updated data on the cluster system, particularly the logistics cluster, to add insights from the empirical domain.FindingsIn practice, the cluster concept has developed from coordination within clusters in response to the inclusion of inter-cluster coordination in preparedness, and more recently a focus on localized preparedness. However, JHLSCM research does not appear to have kept pace, with a few notable exceptions. The majority of its papers still focus on response. To the extent that preparedness is covered, it is primarily done so at the global level.Originality/valueThe authors use a framework to discuss humanitarian logistics coordination research and identify important gaps. Based on developments in practice, the study’s key contribution is a revised model with suggestions for further research.

Raman spectroscopy enables nondestructive, label-free imaging with unprecedented molecular contrast, but is limited by slow data acquisition, largely preventing high-throughput imaging applications. Here, we present a comprehensive framework for higher-throughput molecular imaging via deep-learning-enabled Raman spectroscopy, termed DeepeR, trained on a large data set of hyperspectral Raman images, with over 1.5 million spectra (400 h of acquisition) in total. We first perform denoising and reconstruction of low signal-to-noise ratio Raman molecular signatures via deep learning, with a 10× improvement in the mean-squared error over common Raman filtering methods. Next, we develop a neural network for robust 2-4× spatial super-resolution of hyperspectral Raman images that preserve molecular cellular information. Combining these approaches, we achieve Raman imaging speed-ups of up to 40-90×, enabling good-quality cellular imaging with a high-resolution, high signal-to-noise ratio in under 1 min. We further demonstrate Raman imaging speed-up of 160×, useful for lower resolution imaging applications such as the rapid screening of large areas or for spectral pathology. Finally, transfer learning is applied to extend DeepeR from cell to tissue-scale imaging. DeepeR provides a foundation that will enable a host of higher-throughput Raman spectroscopy and molecular imaging applications across biomedicine. ispartof: ANALYTICAL CHEMISTRY vol:93 issue:48 pages:15850-15860 ispartof: location:United States status: published

Voluntary networks are actors in civil society and central to the emergency preparedness efficiency of developed countries’. This study focuses on the voluntary defense networks in Sweden, a unique set of networks that contribute to the efficiency of emergency preparedness. Through interviews with experts in Swedish civil and military fields and their associated voluntary defense networks, as well as secondary data, we examined the coordination of these voluntary defense networks in practice. Although voluntary network coordination is highly associated with efficiency, in practice, most voluntary networks are not well coordinated. This study confirms that civil and military practitioners in developed countries, struggling with the coordination of voluntary networks are not isolated in their struggle; inattentive practices are indeed the norm. This article also establishes a course that civil and military practitioners can follow to improve emergency response efficiency. RESUMEN Las redes voluntarias son actores de la sociedad civil e importantes para la eficiencia en la preparación de emergencia de los pases desarrollados. Este estudio es sobre las redes de defensa voluntarias en Suecia, un conjunto único de redes voluntarias que contribuyen a la eficiencia de la preparación para emergencias. Las entrevistas con expertos en el campo civil y militar sueco y sus redes de defensa voluntarias asociadas y datos secundarios expusieron el examen de la coordinación de la red de defensa voluntaria en la práctica. La coordinación voluntaria de la red está significativamente asociada con la eficiencia, pero en la práctica, la mayoría de las redes voluntarias no están bien coordinadas. Si los profesionales civiles y militares de los países desarrollados están luchando con la coordinación de redes voluntarias, este estudio confirma que no son únicos en su lucha. La práctica indiferente es de hecho la norma. Los profesionales civiles y militares pueden seguir una ruta adecuada aquí establecida cuando se busca mejorar la eficiencia de la respuesta de emergencia.

The number of organisations involved in relief work in general and humanitarian logistics specifically is large and increasing, creating new complexity. In this paper we analyse different types of coordination and roles in two case studies of the humanitarian cluster system based on its initial development and the Kenyan Post-election crisis. The different and unclear roles of the organisations create significant problems before and after cluster activation and deactivation. Individual organisations take on many roles in the cluster system and beyond it in terms of coordination. The clarity of the roles affects the need for and ease of coordination. We suggest a simple basic categorisation of roles as a starting point for developing this concept in the field of humanitarian logistics and connect this to coordination.

Purpose– The purpose of this paper is to understand the needs of the supply-chain (SC) network when coping with permanent and temporary demands, this paper analyzes the Swedish emergency preparedness SC network. This network comprises planning procedures and resources, as well as numerous organizations and other participants in civil society that take part in the system to cope with threats and ongoing crises. Planning constitutes a critical infrastructure because the system must develop the ability to shift SC functions from permanent to temporary networks in ongoing crises and war.Design/methodology/approach– A research study is performed based on data gathered by three qualitative methods concerning the SC network of emergency preparedness planning.Findings– This study demonstrates the relevance of a wide empirical field challenging several theoretical perspectives of the SC network in preparedness planning and the shift to ongoing crises. Further research targeting key capabilities is needed to further improve understanding of the challenges for developed countries in managing potential threats and crises.Originality/value– Actors taking part in the preparedness system have found it challenging to coordinate. Due, in part, to the lack of a common threat profile, key capabilities remain outside preparedness planning, e.g., military, commercial and voluntary actors as well as unclear and inconsistent regulations. Thus, building the SC network demonstrates the need to target the military, the voluntary and commercial sectors and their ability to develop the networks in preparedness planning. In a reformed system, all actors must strengthen civil defense in an all-hazard approach, which in planning encompasses the entire threat scale, demonstrating key functions and the ability to shift to temporary networks responding to ongoing crises, including war.

PurposeThe purpose of this paper is to improve the understanding of the role of humanitarian cluster leads through applying lessons from the fourth‐party logistics (4PL) literature.Design/methodology/approachThe primary data for this paper are based on an extensive case study of coordination mechanisms in humanitarian logistics covering specifically the UNJLC (United Nations Joint Logistics Centre) and the Logistics Cluster. In total, 37 semi‐structured interviews were conducted, together with site visits and review of official documentation.FindingsThe paper finds that the 4PL concept provides a partial match for the cluster leads with important lessons from the 4PL literature. In particular, lessons are related to selectivity of central participants for the cluster, and the need to develop relationship management skills.Research limitations/implicationsThe paper shows some clear areas where lessons from the 4PL literature are highly relevant to the logistics cluster lead. Some of these implications can also be applied to the other clusters, but further concepts should be developed for the cluster system as a whole.Social implicationsThe analysis shows that cluster leads should think of themselves more as facilitators rather than channel captains.Originality/valueThe tasks for the humanitarian cluster leads have been outlined in some detail, but the ways to accomplish them and how they should operate in relation to other actors in the field has been less clear. By using the 4PL concept the paper demonstrates a number of lessons that are relevant to the logistics cluster lead in particular.

PurposeThere is a need for theory development within the field of humanitarian logistics to understand logistics needs in different stages of a crisis and how to meet these. This paper aims to discuss three dimensions identified in logistics and organization theories and how they relate to three different cases of humanitarian logistics operations – the regional concept of the International Federation of Red Cross Red Crescent Societies, the development and working of the United Nations Joint Logistics Centre and coordination challenges of military logistics in UN mandated peacekeeping operations. The purpose is to build a framework to be used in further studies.Design/methodology/approachA framework for the study of humanitarian logistics along three dimensions is developed, followed by a discussion of the chosen cases in relation to these dimensions. The framework will be used as basis for the case studies to be undertaken for the purpose of understanding and identification of new questions and needs for other or revised concepts from theory.FindingsThe paper shows the relevance of a wide literature to the issues pertinent to humanitarian logistics. There is considerable promise in extant literature on logistics, SCM and coordination, but this needs to be confronted with the particular issues seen in the humanitarian logistics setting to achieve further theory development.Originality/valueThe major contribution of the paper lies in its breadth of theoretical perspectives presented and combined in a preliminary theoretical framework. This is applied more specifically in the three case studies described in the paper.

The concept of a fourth-party logistics provider is increasingly explored in the literature and has come to focus on firms that are able to organize and run significant parts of a supply chain. These firms are assigned increasing responsibility for design, recruitment of other firms and maintenance of supply chains due to very specific skills. Within the humanitarian sector there is considerable reorganization of the necessarily agile supply chains necessary to deliver relief during disasters. This reorganization has included the designation of clusters for different types of activity, and significantly leadership of the cluster to specific organizations. This article applies the concept of a fourth-party logistics provider on the cluster concept to help develop a concept for how the cluster leads themselves should operate.
