Abstract:
For vibration control of long-span arch bridges under multi-support seismic excitation, this paper presents schemes of control to seismic responses of arch bridges with Magneto-Rheological dampers(MRD). In the semi-active control system of arch bridge-MRD, Linear Quadratic Gaussian (LQG)-based Sign function control algorithm is used to command MRD，and traveling wave effects on the responses of structure are considered. The Nimu arch bridge is used as a simulation example to verify the proposed control scheme. Numerical results show that traveling wave effects have no unfavorable influence on the control to response of arch bridge.

Abstract:
Urban overpasses, being long-span linear projects, are inevitably affected by ground fissure activities. This study focused on the three-span continuous overpass, and used the MIDAS GTS NX finite element simulation software to establish the model of an urban overpass crossing active ground fissures with different straddling ground fissure positions and hanging wall settlements. This study analyzed the deformation and stress characteristics of soil and bridges induced by ground fissures under different working conditions. The results demonstrate that the soil’s displacement response is mainly concentrated near the ground fissures, and the displacement changes decrease with increasing ground fissures. Ground fissure activities redistribute the stress inside the beam and pier, resulting in the tilting of the pier. When the fissure activity is small, the use of multi-span beams to straddle the ground fissures can effectively reduce the influence of ground fissure activities on bridge deformation. However, when the fissure activity is significant, the bridge may be damaged, and excessive deformation of the bridge and piers may not meet code requirements. In such cases, the multi-span beam structure type should be changed to adapt to the ground fissure activity. The research results provide significant reference value for urban traffic planning and overpass design.

Abstract:
In general, the structures of Multi-Active Bridge (MAB) converters that can be found in the literature are usually based on voltage converters. However, in some cases, it could be interesting to have a current-fed input due to load characteristics or operation constraints. This leads to a hybrid MAB structure mixing both current-fed and voltage-fed bridges. In this paper, a new hybrid-fed, fully coupled Triple-Active Bridge (TAB) converter topology with two voltage-fed ports and one current-fed port is studied, modelled and controlled. In the first place, a generalized average model (GAM) is developed for this system. After that, a reduced-order model is elaborated in order to simplify the behavioral study and control of this coupled system. A control strategy was also proposed in this paper, based on the developed mathematical model. Simulation results using Matlab/Simulink are presented to validate this study.

Abstract:
The dual-active-bridge converter (DAB) has attracted tremendous attention in recent years. However, its EMI issues, especially the high-frequency oscillation (HFO) induced by the dv/dt and parasitic elements of the transformer, are significant challenges. The multi-active-bridge converter (MAB) based on the multi-winding transformer also faces similar problems, which are even more complicated. This article investigates the HFO of active-bridge-transformer-based DC/DC converters including DAB and MAB. Firstly, the general HFO model is studied using the analysis of the AC equivalent circuit considering the asymmetrical parameters. Ignoring the AC resistance in the circuit, the high-order model of the voltage oscillation could be reduced to a second-order system. Based on the simplified model, the oscillation voltage generated by an active bridge is analyzed in the time domain. Then, a universal active voltage-oscillation-suppression method-selected harmonic-elimination phase-shift (SHE PS) modulation method is proposed. The impacts of the system parameters on the method are also revealed. The experimental results show the excellent performance of the proposed active suppression method, with voltage spike amplitude (VSA) reductions of 92.1% and 77.8% for the DAB and MAB prototypes, respectively.

Abstract:
Muscle contraction results from force-generating cross-bridge interactions between myosin and actin. Cross-bridge cycling kinetics underlie fundamental contractile properties, such as active force production and energy utilization. Factors that influence cross-bridge kinetics at the molecular level propagate through the sarcomeres, cells and tissue to modulate whole-muscle function. Conversely, movement and changes in the muscle length can influence cross-bridge kinetics on the molecular level. Reduced, single-molecule and single-fibre experiments have shown that increasing the strain on cross-bridges may slow their cycling rate and prolong their attachment duration. However, whether these strain-dependent cycling mechanisms persist in the intact muscle tissue, which encompasses more complex organization and passive elements, remains unclear. To investigate this multi-scale relationship, we adapted traditional step-stretch protocols for use with mouse soleus muscle during isometric tetanic contractions, enabling novel estimates of length-dependent cross-bridge kinetics in the intact skeletal muscle. Compared to rates at the optimal muscle length ( L o ), we found that cross-bridge detachment rates increased by approximately 20% at 90% of L o (shorter) and decreased by approximately 20% at 110% of L o (longer). These data indicate that cross-bridge kinetics vary with whole-muscle length during intact, isometric contraction, which could intrinsically modulate force generation and energetics, and suggests a multi-scale feedback pathway between whole-muscle function and cross-bridge activity.

Abstract:
Un convertisseur à multiples ponts actifs, appelé aussi convertisseur MAB (pour Multi-Active Bridge converter en anglais), est une topologie intéressante de « Hub Energétique » qui a apparu récemment. Dans un Hub Energétique, la production, la consommation et le stockage de l'énergie électrique ont lieu au sein de la même structure. De plus, les convertisseurs MAB sont des convertisseurs multiports dotés d'une isolation galvanique intrinsèque. Celle-ci est obtenue en connectant les ports de cette topologie par l'intermédiaire d'un transformateur haute fréquence (HF). L'isolation galvanique est nécessaire pour les applications où différentes sources d'alimentation/charges présentant d'importantes dissimilitudes de tensions et de puissances nominales doivent être connectées ensemble. Par conséquent, un convertisseur MAB peut connecter plusieurs sources d'énergie, charges et systèmes de stockage d'énergie électrique ensemble, permettant un flux d'énergie multidirectionnel entre eux. Pour toutes ces raisons, les convertisseurs MAB ont dernièrement attiré beaucoup l'attention, notamment pour les applications sollicitant des sources d'énergie renouvelables et des systèmes de stockage d'énergie.En général, l'objectif principal du contrôle d'un convertisseur MAB est de gérer les flux de puissance active entre ses ports en fonction des besoins de chacun d'entre eux. Cependant, l'optimisation du contrôle de ce convertisseur peut être réalisée en ajoutant des contraintes, visant à minimiser les pertes du système par exemple.Dans cette thèse, le modèle mathématique d'un convertisseur MAB est développé pour représenter son comportement en régime transitoire et en régime permanent. Ce modèle est ensuite utilisé pour élaborer une méthode de calcul des pertes de conduction et de commutation du convertisseur MAB à n'importe quel point de fonctionnement. Une stratégie de commande optimisée est proposée dans le but de minimiser les pertes totales du système sur toute sa plage de fonctionnement. Cette stratégie de commande utilise le modèle mathématique et la méthode de calcul des pertes développés pour prédire la combinaison optimale des paramètres de contrôle aboutissant à des pertes minimales pour tout point de fonctionnement désiré.Un prototype d'un convertisseur MAB à quatre ports (Quadruple Active Bridge) est construit et des résultats expérimentaux sont présentés dans le manuscrit pour démontrer la fiabilité du modèle mathématique et l'efficacité de la stratégie de commande proposée dans cette thèse.En général, les structures MAB sont basées sur des convertisseurs alimentés en tension. Cependant, dans certaines applications, il peut être utile d'avoir un port alimenté en courant en raison des caractéristiques de la charge ou des contraintes opérationnelles. Cela conduit à une structure MAB hybride qui mélange à la fois des ponts alimentés en courant et des ponts alimentés en tension. Dans la dernière partie du manuscrit, une nouvelle topologie de convertisseur MAB à alimentation hybride est présentée et étudiée. Son modèle mathématique est développé et une stratégie de commande est proposée. Des résultats de simulation sont fournis afin de valider l'étude théorique présentée<br>A Multi-Active Bridge (MAB) converter is an interesting energy hub topology that has emerged in recent years. In an energy hub, the production, consumption and storage of electrical energy all take place within the same structure. In addition, MAB converters are multiport converters with intrinsic galvanic isolation. This is achieved by connecting the ports of this topology through a high-frequency (HF) transformer. Galvanic isolation is crucial for applications where different power sources/loads with important voltage dissimilarities and power ratings need to be connected together. Consequently, a MAB converter can connect several energy sources, loads and energy storage systems together, allowing multidirectional power flow between them. For these reasons, MAB converters are attracting great attention in many applications, especially those requiring energy storage and/or integration of renewable energy sources.In general, the main objective of controlling a MAB converter is to manage the active power flows between its ports based on each port's requirements. However, optimizing the control of this converter can be achieved by adding another constraint, aiming to minimize the system’s losses for example.In this thesis, the mathematical modelling of a selected MAB converter topology is first developed to represent its steady-state and dynamic behaviour. This developed model is then used to elaborate a method for calculating the conduction and switching losses of the MAB converter at any operating point and for any combination of its control parameters. After that, an optimized control strategy is proposed with the aim of minimizing the total system losses over the entire operating range of the MAB converter. The proposed control strategy uses the developed mathematical model and the loss calculation method to predict the optimal combination of the control parameters resulting in minimum losses, and therefore an increased efficiency for any desired operating point.A four-port 4×500 W prototype of a MAB converter (Quadruple Active Bridge) is built and experimental results are presented to demonstrate the reliability of the mathematical model and to prove the effectiveness of the proposed control strategy.In general, MAB structures are based on voltage converters. However, in some applications, it may be useful to have a current-fed input port due to load characteristics or operational constraints. This leads to a hybrid MAB structure that mixes both current and voltage-fed bridges. In the final part of the manuscript, a novel hybrid-fed MAB converter topology is presented and evaluated. Its mathematical model is developed and a control strategy is proposed. Simulation results are provided in order to validate the presented theoretical study

Abstract:
Alexei Ratmansky’s production of Sleeping Beauty was wrought with careful attention to its music and the manuscripts that preserve Petipa’s choreography. This article begins by touching generally on some aspects of the original ballet that Ratmansky has restored: its technique and style, large multi-generational cast, and full embrace of character dancing. Next, it focuses on musical and choreographic characterizations of the felicitous royal family and their servant Catalabutte and their domestic interactions. Then, it considers Ratmansky’s effective use of the episodes of tension and release that Petipa and Tchaikovsky created to push the action forward. It ends with a short discussion of seeming conflicts between choreography and music during musical codettas, These few details show in small part how, in this production, Ratmansky has exposed anew the dramaturgical brilliance of Tchaikovsky and Petipa, and restored to the stage a Beauty that brings story and character to life with extraordinary vividness.

Abstract:
Kūṭiyāṭṭam, India’s only living traditional Sanskrit theatre, has been continually performed in Kerala for at least a thousand years. The actors and drummers create an entire world in the empty space of the stage by using spectacular costumes and make-up and by an immensely rich interplay of words, rhythms, mime, and gestures. This volume focuses on Mantrāṅkam and Aṅgulīyāṅkam, the two great masterpieces of Kūṭiyāṭṭam. It provides fundamental general remarks and relates them to pan-Indian reflections on aesthetics, philology, ritual studies, and history. Authored by scholars and active Kūṭiyāṭṭam performers, this is the first attempt to bring together a set of sustained, multi-faceted interpretations of these masterpieces-in-performance. With an aim to open up this ancient art form to readers interested in South Indian culture, religion, theatre and performance studies, philology, as well as literature, this volume offers a new way to access a major art form of pre-modern and modern Kerala. The University of Tuebingen in Germany and the Hebrew University of Jerusalem in Israel were partners in a long-term project studying and documenting Kūṭiyāṭṭam performances, including initiating full-scale performances of major works in the classical repertoire. We have been, in particular, focusing on the study of the two major, complex and ancient works, Mantrāṅkam and Aṅgulīyāṅkam, both of which we have seen and recorded in full. The articles in this volume are one of the results. They are supplemented with video-clips of lecture demonstrations provided online.

Abstract:
Charles Dickens was the most popular writer of his age and is still considered one of the world's greatest novelists. This well-written study surveys his unusual and prolific life, relating his fiction writings to his concerns and active involvement with social conditions of early Victorian England. Glancy skillfully takes the reader back in time to appreciate the historical settings that inspired works likeOliver Twist, Great Expectations, andA Tale of Two Cities. An entire chapter is devoted to each of these works, as well as toDavid Copperfield, Hard Times, the Christmas books, and the early novels fromThe Pickwick PaperstoMartin Chuzzlewit. In each chapter Glancy's analysis of plot, style, and character development bring these imaginative stories to life for the reader. This book examines Dickens's keen understanding of human nature and draws out the themes that make works such asA Christmas Carolas beloved today as when first written. This companion to Dickens will aid students in understanding the social context and literary genius of one of the greatest Victorian novelists. The thorough biographical chapter traces Dickens' life from his childhood through the development of his multi-faceted literary career. The literary heritage chapter examines the tremendous influence Dickens exerted on writing then and now. This volume surveys all of Dickens' work and provides in-depth readings of five of his novels and his Christmas works. The series format makes analysis of setting, plot, character development, and themes for each work accessible to students. The alternate critical perspectives enhance readers' understanding of Dickens' work. The selected bibliography and reviews cover both original and contemporary sources.

Abstract:
Queer Dance argues that dance has a particular charge in the larger field of queer activism and study because it emphasizes and offers language for how public, physical action can be a force of social change. It considers how queer dance has political potential and how it could productively challenge more conservative dance forms, both in terms of making meaning and in terms of institutional practices. Queer Dance brings together artists and scholars in a multi-platformed project—book, website, and live performance series—to ask: “What does dancing queerly challenge us toward?” The artists and scholars whose writing appears in the book and whose performances and filmed interviews appear online, stage a wide range of genders and sexualities as a way to challenge and destabilize social norms. Queer dance is a coalitional project, a gathering that works across LGBTQ identities and in concert with feminist, anti-racist, and anti-colonial artmaking, activism, and scholarship. The book engages with dance-making, dance scholarship, queer studies, and a host of other fields, always asking how identities, communities, and artmaking and scholarly practices might consider what queer work the body does and can do. Might the slide of a hand across a hipbone be just as much an act of coming out as an announcement offered in words? How does queerness exist in the realm of affect and touch, and what then might be revealed about queerness through these pleasurable and complex bodily ways of knowing?

AbstractThis chapter offers an exploration of the methodological potentials, challenges, and pitfalls associated with conducting multimodal research on patterns of digital socialisation during leisure, while focusing on the involvement of children as co-researchers. A comprehensive research design is suggested for investigating children and young people’s digital leisure activities using a multimodal approach. This design aims to explore communication and representations by leveraging an innovative process of integrating and interpreting information from diverse modalities. This process, known as semantic data integration, allows for a cohesive analysis of multimodal data, enabling a deeper understanding of the subject matter. The design emphasises the active involvement of research contributors, who not only participate as subjects but also play a role as co-researchers. The chapter provides a detailed description and critical assessment of the methodologies adopted across all parts of the fieldwork conducted to investigate children’s online leisure habits and digital technologies use and identifies the significant qualities of a multimodal and multi-method approach. The methods are evaluated to deliver suggestions for practises that can be adopted in having children play an active part through research implementation. Semantic integration is suggested to bridge the gap between different modalities and extract comprehensive understanding of collected data.

Abstract:
AbstractCities play a fundamental role in the global challenge of climate change, but in most cases financial obstacles and lack of skilled human resources restrain the development of transformative actions. The recovery from Covid-19 pandemics brings a new stimulus for urban sustainable transitions, allocating a large amount of monetary resources for urban regeneration initiatives connected with the SDGs and the Green Deals objectives. Indeed urban regeneration emerges as a key mechanism to address both post-pandemics recovery and climate challenges, facilitating the implementation of urban mitigation and adaptation measures. District-scale projects can become enablers of city-wide sustainable transition, allowing the experimentation of innovative technical solutions to activate multi-systemic transformations. A large literature has been produced over the last 20 years over the topics of Urban Resilience and Sustainable Transition. Nevertheless a multi-sectoral approach to district-scale transformations is just emerging and needs to be integrated through evidences from best practices. This paper aims to identify a portfolio of measures able to transform existing neighborhoods into zero-carbon and climate-resilient systems. With this purpose, two case studies have been explored as paradigmatic examples of sustainable district redevelopment, and namely the Clichy-Batignolles eco-district (Paris) and the Talbot-Norfolk Triangle Eco-Innovation District (Boston).

Abstract:
AbstractThe aim of this chapter is to investigate histospheres as multi-immersive perceptual spaces that not only model a historical world but also profoundly influence our conceptions and interpretations of history. In this context, the first section examines the role of aesthetically modeled atmospheres and the moods they evoke. The second section builds on this examination by considering filmic space. Filmic atmospheres and spatial figurations of movement bring us physically and mentally closer to the action of the film. Another potent mechanism of perspectivation is film characters, and so the third section focuses on imaginative empathy with the characters who inhabit a film’s historical world. In combination with film experience as a mode of embodied perception, this inner perspective provokes interpretations and evaluations that we can extend to the filmic depiction’s historical references.

AbstractIn an era of global challenges – from climate change to economic unrest to social disruption to pandemics – the need to hear from voices of the next generation of leaders is clear. The time to listen to them is now. The purpose of this book is to assemble, organize, and amplify the knowledge and experiences of some of the world’s young people who are working locally and collectively to use scientific results, geospatial technologies, and multi-national collaboration to address some of the most pressing issues facing their local communities and global society. From every region of the world, students have emerged as leaders in the YouthMappers movement, to study such problems by creating and using open data that has a spatial component. The issues they are addressing with these common tools and methods range across the entire scope of topics known as the Sustainable Development Goals, articulated globally through the United Nations. Not only do YouthMappers create new knowledge and bring unique perspectives and experiences, but they are also proposing and taking action based upon what they see and what they know from the map and from each other.

Abstract:
AbstractGray whale sexual behavior and copulation are observed throughout their range. The most prominent period for reproductive behavior is during the southward migration from summer feeding areas to wintering areas where some breeding occurs and calves of the year are reared. The seasonal migrations of gray whales are believed to function, in part, to bring together individuals that are otherwise widely distributed during the period of estrus to facilitate mating and reproduction. Sexual behaviors and sexual strategies for this species appear to align closely with those of balaenid (not rorqual) whales, although such comparisons need further investigation. Gray whales are polygynandrous (multi-mate) breeders. There does not appear to be female choice of mates, as groups of numerous females and males aggregate, and multiple copulations occur. Female estrus begins in mid-November and continues to early December; females may undergo a second estrus, extending into February, if they fail to conceive during their first cycle. Male gray whales have large testes and concomitantly produce large volumes of sperm, so they are believed to be sperm competitors; that is, they rely on multiple copulations (and sperm volume) to produce offspring. Multiple copulations with different males during the female estrus period may increase the likelihood that the timing of conception results in the birth of a calf approximately 13 months later near or in the wintering area(s). Mating bouts can last for minutes to hours, interspersed with surface-active-social-sexual behavior. Some all-male groups have been observed with erect penises engaged in social-sexual behavior in the absence of any females. Instances of male aggression toward postpartum females with calves of the year, sometimes resulting in injury or death, have been reported. As a result of dedicated long-term research in the past several decades, the state of knowledge on gray whale reproduction has greatly expanded and updated information on this topic is summarized in this chapter.

Abstract:
Agent Oriented Software-Engineering (AOSE) proposes the design of distributed software systems as collections of autonomous and pro-active actors, so-called agents. Since software applications results from agent interplay in Multi-Agent Systems (MAS), this design approach facilitates the construction of software applications that exhibit self-organizing and emergent dynamics. In this chapter, we examine the relation between self-organizing MAS and Complex Adaptive Systems (CAS), highlighting the resulting challenges for engineering approaches. We argue that AOSE developers need to be aware of the possible causes of complex system dynamics, which result from underlying feedback loops. In this respect current approaches to develop SO-MAS are analyzed, leading to a novel classification scheme of typically applied computational techniques. To relieve development efforts and bridge the gap between top-down engineering and bottom-up emerging phenomena, we discuss how multi-level analysis, so-called mesoscopic modeling, can be used to comprehend MAS dynamics and guide agent design, respectively iterative redesign.

Abstract:
The Pacific Earthquake Engineering Research Center (PEER) is a multi-institutional research and education center with headquarters at the University of California, Berkeley. PEER’s mission is to develop, validate, and disseminate performance-based seismic design technologies for buildings and infrastructure to meet the diverse economic and safety needs of owners and society. The year 2016 began with a change of leadership at PEER. On January 1, Professor Khalid Mosalam became the new PEER Director as Professor Stephen Mahin completed his 6- year term. Also in early 2016, Dr. Yousef Bozorgnia stepped down from the position of Executive Director, after serving as a key member of PEER’s management team for over 12 years. Several accomplishments of the Center during the leadership of Director Mahin were recounted during the PEER Annual Meeting on January 28–29, 2016. This meeting also set the course of the Center with several new thrust areas identified for future research. During the past year, PEER has continued its track record of multi-institutional research with several multi-year Mega-Projects. The PEER Tall Buildings Initiative (TBI) was recently expanded to include assessment of the seismic performance of existing tall buildings. The California Earthquake Authority (CEA) awarded a $3.4 million, 3.5-year research contract to PEER to investigate the seismic performance of wood-frame homes with cripple walls. The project will directly contribute to the improvement of seismic resiliency of California’s housing stock. Former Director Mahin will lead a broad effort for computational modeling and simulation (SimCenter) of the effects of natural hazards on the built environment. Supported by a 5-year, $10.9-million grant from the National Science Foundation (NSF), the SimCenter is part of the Natural Hazards Engineering Research Infrastructure (NHERI) initiative, a distributed, multi-user national facility that will provide natural hazards engineers with access to research infrastructure (earthquake and wind engineering experimental facilities, cyberinfrastructure, computational modeling and simulation tools, and research data), coupled with education and community outreach activities. In addition to the Mega Projects, PEER researchers were involved in a wide range of research activities in the areas of geohazards, tsunami, and the built environment focusing on the earthquake performance of old and new reinforced concrete and steel structures, tall buildings, and bridges including rapid bridge construction. As part of its mission, PEER participated in a wide range of education and outreach activities, including a summer internship program, seminars, OpenSees days, and participation in several national and international conferences. The Center became an active board member of two prominent international organizations, namely GADRI (Global Alliance of Disaster Research Institutes) and ILEE (International Laboratory of Earthquake Engineering). PEER researchers and projects were recognized with awards from several organizations. Going forward, PEER aims to improve the profile and external exposure of the Center globally, strengthen the Business-Industry-Partnership (BIP) program, engage the Institutional Board (IB) and the Industry Advisory Board (IAB) to identify new areas of research, and explore new funding opportunities.

Goeckeritz, Joel, Nathan Schank, Ryan L Wood, Beverly L Roeder, and Alonzo D Cook. Use of Urinary Bladder Matrix Conduits in a Rat Model of Sciatic Nerve Regeneration after Nerve Transection Injury. Science Repository, 2022. http://dx.doi.org/10.31487/j.rgm.2022.03.01.

Full text
Abstract:
Previous research has demonstrated the use of single-channel porcine-derived urinary bladder matrix (UBM) conduits in segmental-loss, peripheral nerve repairs as comparable to criterion-standard nerve autografts. This study aimed to replicate and expand upon this research with additional novel UBM conduits and coupled therapies. Fifty-four Wistar Albino rats were divided into 6 groups, and each underwent a surgical neurectomy to remove a 7-millimeter section of the sciatic nerve. Bridging of this nerve gap and treatment for each group was as follows: i) reverse autograft—the segmented nerve was reversed 180 degrees and used to reconnect the proximal and distal nerve stumps; ii) the nerve gap was bridged via a silicone conduit; iii) a single-channel UBM conduit; iv) a multi-channel UBM conduit; v) a single-channel UBM conduit identical to group 3 coupled with fortnightly transcutaneous electrical nerve stimulation (TENS); vi) or, a multi-channel UBM conduit identical to group 4 coupled with fortnightly TENS. The extent of nerve recovery was assessed by behavioural parameters: foot fault asymmetry scoring measured weekly for six weeks; electrophysiological parameters: compound muscle action potential (CMAP) amplitudes, measured at weeks 0 and 6; and morphological parameters: total fascicle areas, myelinated fiber counts, fiber densities, and fiber sizes measured at week 6. All the above parameters demonstrated recovery of the test groups (3-6) as being either comparable or less than that of reverse autograft, but none were shown to outperform reverse autograft. As such, UBM conduits may yet prove to be an effective treatment to repair relatively short segmental peripheral nerve injuries, but further research is required to demonstrate greater efficacy over nerve autografts.

Advancing disability-inclusive action on internal displacement. Internal Displacement Monitoring Center (IDMC), 2022. http://dx.doi.org/10.55363/idmc.pbqj8456.

Full text
Abstract:
A record 59.1 million people were internally displaced as a result of conflict, violence and disasters at the end of 2021. How many were living with disabilities is unknown, but the global disability prevalence rate of 15 per cent suggests the figure could be nearly nine million. IDMC has led the production of the first collaborative report on internally displaced persons (IDPs) with disabilities in situations of conflict, violence and disasters. The report brings together inputs from CBM, the European Disability Forum, Humanity &amp; Inclusion, the Inclusive Data Charter, IMPACT Initiatives, Ruhr University Bochum - Institute for International Law of Peace and Armed Conflict, the Stakeholder Group of Persons with Disabilities and UNHCR. This report represents a first step toward addressing the paucity of data on IDPs with disabilities. Its findings highlight the differentiated and multi-dimensional impacts of displacement on the lives of persons with disabilities and the intersecting challenges they face before, during and after displacement. It also includes a Spotlight on IDPs with disabilities in Ukraine.

Root Causes of Low Vaccination Coverage and Under-Immunisation in Sub-Saharan Africa Report. Academy of Science of South Africa, 2021. http://dx.doi.org/10.17159/assaf.2019/0068.

Full text
Abstract:
Sub–Saharan Africa (SSA) alone accounts for 40% of all global deaths, a phenomenon attributed to lack of access to available lifesaving vaccines (Wiysonge, Uthman, Ndumbe, &amp; Hussey, 2012). WHO estimates that in 2019 the African region accounted for approximately 43% of unimmunised and incomplete immunised infants in the world (i.e.: 8.5 million of the global 19.4 million). Relatedly, the region scores the lowest immunisation coverage, at 76% versus the global coverage of 86% (WHO, 2020a). This is despite several documented efforts by different stakeholders to improve coverage in the region (Mihigo, Okeibunor, Anya, Mkanda, &amp; Zawaira, 2017). Many studies have been conducted on coverage and drivers for and bottlenecks against immunisation in SSA. (Wiysonge, Uthman, Ndumbe, &amp; Hussey, 2012), (Wiysonge, Young, Kredo, McCaul, &amp; Volmik, 2015), (Mihigo, Okeibunor, Anya, Mkanda, &amp; Zawaira, 2017), (Madhi &amp; Rees, 2018),(Bangura, et al., 2020), all of which have observed that there is varied performance among the constituent countries, and also within countries over time, denoting some implicitly common underlying correlates threading through areas of higher performance; and the same is seen with the poorer performing areas. This consensus study therefore seeks to categorise and make explicit these “root causes” and based on documented successes, to make recommendations to address the bottlenecks and harness the opportunities for reaching every child with all the recommended vaccines. The theory of change presentation style used in this report, categorising the root causes under four broad interlinked themes, can provide a common basis to rally like-minded partners around a thematic cause and thus develop multi-component, comprehensive strategies to bring about impactful change. This is in line with the call made by the World Health Organisation Strategic Advisory Group of Experts on Immunisation, which recommended that countries, regions and global immunisation partners commit to a comprehensive review of progress, impact, and implementation of the WHO Global Vaccine Action Plan to inform a post-2020 strategy taking into account lessons learned. This strategy will assist with attaining the relevant United Nations Sustainable Development Goals by 2030.
