Resumen
Abstract Marathon Oil gets its Corporate Emergency Response Team (CERT) together once a year in a tabletop exercise. CERT is made up of volunteers from throughout the company and the exercise serves both to hone response skills and to build teamwork. The 2009 annual exercise was held in Huntington, West Virginia. The exercise involved a diesel leak in Ohio, a worst case discharge of crude oil in Kentucky and a barge/security incident in West Virginia. These incidents pulled in responders from 3 United States Environmental Protection Agency (USEPA) regions, the United States Coast Guard (USCG), West Virginia National Guard, 3 states, 4 counties and 3 business units. In all 280 people from 26 organizations were involved in the drill. The planning effort involved many of the organizations who played in the exercise and was modeled after the Spill of National Significance (SONS1) 2007 planning effort for the Evansville Venue which built from the bottom up. Major goals of the drill were to: deeply integrate Unified Command, and stress the CERT with both traditional and nontraditional problems. The endgame was the delivery of an Incident Action Plan (IAP) which included the company's first attempt at an inland salvage plan. Unified Command was pushed down into Operations, Planning, Environmental and Joint Information. Integration in Unified Command was done in several ways: traditional jurisdictional decision making, position/task assignments, and resource pooling. A Joint Information Center (JIC) was setup for the exercise, and one of the JIC's tasks was to accommodate real media coverage. A group hotwash was held for all participants and even though 100 action items were identified, the group consensus was that the drill was valuable for both public and private responders, and their organizations.

Resumen
Recently, as a promising lighting source, light-emitting diodes (LEDs) have become more and more attractive and have great opportunity to replace traditional lighting sources - incandescent, fluorescent and HID because of the advantages such as high luminous efficacy, long lifetime, quick on/off time, wide color gamut, eco-friendly etc. Based on the research from U.S. Department of Energy, over 30% of total electric consumption in U.S. each year is for lighting, 75% of which are for indoor lighting (including both residential and commercial buildings). In the indoor LED lighting application, to provide multiple current source outputs for multiple LED strings, traditional solutions usually adopt a two-stage structure, which is complicated and cost-ineffective. How to design a simple, low-cost and efficient LED driver with multiple current source outputs is in great demand and really challenging. In this thesis, a single-stage multi-channel constant current (MC3) LED driver structure has been proposed. Multiple transformer structure is utilized to provide multiple current source outputs. The current control scheme is also simple - only one LED string current is sensed and controlled; other strings' currents are cross regulated. Firstly, a PWM half bridge topology is chosen to implement the proposed single-stage MC3 LED driver concept. In order to analyze the current cross regulation, a general model is derived. The circuit has been simulated under various LED load conditions to verify its good current sharing capability. In order to further improve efficiency, simplify the driver's complexity and reduce cost, a LLC resonant topology is also investigated. LLC current gain characteristic has been derived by considering LED's i-v character and a design procedure is developed. A 100 kHz, 200 W, 4-string MC3 LLC LED driver is designed and tested. The experimental results show that the driver can maintain constant current output within the whole input and output variations, achieve good efficiency and realize current sharing under both balanced and unbalanced LED conditions. The dimming function can also be realized through frequency modulation method and burst mode control method. As a conclusion, a single-stage MC3 LED driver concept is proposed and implemented with two topologies. The proposed idea provides a simple, low-cost and efficient solution for indoor LED lighting application with multiple LED string configuration. It also has good current sharing capability and robustness to LED forward voltage variations or short failures.

Resumen
LED is widely used in many applications, such as indoor lighting, backlighting and street lighting, etc. For these application, multiple LED strings structure is adopted for reasons of cost-effectiveness, reliability and safety concerns. Several methods and topologies have been proposed to drive multiple LED strings. However, the output current balance and efficiency are always the two major concerns for LED driver. A simple two-stage multi-channel LED driver is proposed. It is composed of a buck converter as the first stage and a multi-channel constant current (MC3) CLL resonant converter as the second stage. For the CLL resonant converter, the magnetizing inductance of the transformer can be as large as possible. Therefore, the magnetizing current of the transformer has little influence on the output currents. In addition, the currents of two LED strings driven by the same transformer is balanced by a DC blocking capacitor. As a result, the current balance among LED strings is very good, even if the load is severely unbalanced. Meanwhile, the current flowing through the external inductance Lr1, instead of the magnetizing current is used to help the primary-side switches to achieve ZVS. Therefore, large magnetizing inductance is good for current balance and properly designed Lr1 is helpful for ZVS achievement. These properties of MC3 CLL are preferred to drive multi-channel LED strings. In the design procedure of MC3 CLL resonant converter, the parasitic junction capacitor of the secondary-side rectifier is taken into account. It influences the operation during dead time significantly when the voltage step-up transformer is applied. The junction capacitors of the secondary-side rectifiers, and the output capacitors of the primary-side switches will resonate with the inductor Le2 during the dead time. Finally, this resonance impact the ZVS achievement of the primary-side switches. Therefore, the inductors Lr1 and Le2 should be designed according the charge needed to achieve ZVS with considering the resonance. Additionally, the control strategy for this two-stage structure is simple. Only the current of one specific LED string is sensed for feedback control to regulate the bus voltage, and the currents of other LED strings are cross-regulated. Furthermore, the MC3 CLL is unregulated and always working around the resonant frequency point to achieve best efficiency. The compensator is designed based on the derived small signal model of this two-stage LED driver. Due to the special electrical characteristics of LED, the soft start-up process with a delayed dimming signal is adopted and investigated. With the soft start-up, there is no overshoot for the output current. Finally, a prototype of the two-stage LED driver is built. The current balance capability of the LED driver is verified with the experiment. Good current balance is achieved under balanced and severely unbalanced load condition. In addition, the efficiency of the LED driver is also presented. High efficiency is guaranteed within a wide load range. Therefore, this two-stage structure is a very promising candidate for multi-channel LED driving applications.

Resumen
As a growth industry, tremendous cost pressures are pushing the LED lighting market away from traditional power electronics converters and towards solutions that are more unconventional. Lower quality LED lights use simple low-cost converters, whereas high end product may add complexity in order to achieve a more dramatic energy savings. SIMO technology represents an opportunity in LED lighting to combine the low cost of single-stage converters with the energy saving capability of a two-stage, multiple string solution. This paper describes the modeling, analysis, design, and testing of a Multiple Independently Regulated Output Flyback (MIROF) converter, used in LED lighting for the purpose of multiple string control. This converter is based upon SIMO technology applied to a PFC Flyback converter. The result was the development of a novel control method and an operational demonstration unit. A cost comparison of the MIROF and a conventional two-stage driver shows a promising cost reduction benefit for the former, and comparative testing shows favorable performance of the MIROF converter compared to the two-stage approach.

Resumen
Lighting installations are usually static and based on long-standing visual indicators such as colour temperature, colour rendering, and illuminance values. However, we now know that spectral variations in light elicit non-visual effects via a distinct pathway in our brain, and it is important for designers and architects to take these into account: light influences our mood, modulates our attention, can suppress the production of melatonin and can shift our circadian rhythms. Considering all the spectral aspects of light is the initial step towards designing healthier environments that are both pleasant and respectful to our biology. Multi-channel LED light engines can provide the core technology for a truly spectral lighting design, thereby enabling wider applications of light with different purposes. This dissertation aims at facilitating this transition by delivering cost-effective multi-channel LED light engines capable of generating arbitrary spectral shapes. In the first part of this work, we develop a light engine for a research-oriented market and explore novel designs and solutions for an advanced industrial device aimed at tackling a more general lighting market. These two efforts led to the development of two optically and spectrally different devices: the SPECTRA TUNE LAB light engine (with an on-board spectrometer and ten different LED channels), and the VEGA 07 light engine (equipped with a colour sensor and seven different LED channels). Second, to generate arbitrary spectral shapes, we perform an extensive study on different heuristic algorithms implemented directly in the microcontroller of the light engine as well as in its control software. We show that the simulated annealing algorithm provides fast computation times with excellent spectral fidelity. Third, we develop two types of optical feedback controllers with different light sensors to prevent temperature-driven colour and spectral shifts, and the wear-out of the LEDs. Both these sensors, i.e. the spectrometer in the SPECTRA TUNE LAB and the colour sensor in the VEGA 07, are used to ensure high precision and accuracy of the emitted light at all times and for any kind of target spectrum. Finally, we demonstrate the ways in which these devices can be used for different applications, thereby verifying the huge advantages and added value of this technology as compared to traditional lighting systems. Our developed light engines were installed in the intensive care units of two hospitals (Hospital Vall d'Hebron and Hospital Clínic in Barcelona), in office settings (ARUP's office in London), and 24/7 control rooms (Repsol's refinery control room in Tarragona), among others.
Les instal·lacions dil·luminació solen ser estàtiques i basades en indicadors visuals clàssics com la temperatura de color, la representació dels colors o els nivells d'il·luminació. Tanmateix, avui sabem que la llum també té una funció que no és propiament visual i que els arquitectes i dissenyadors haurien de començar a tenir en compte: la llum pot influir en el nostre estat d'ànim, modular la nostra atenció, regular la producció de melatonina o modificar els ritmes circadiaris. Tenir en compte totes les propietats espectrals de la llum és el primer pas per dissenyar entorns més sans i respectuosos amb la nostra biologia. Així, el disseny i desenvolupament de noves fonts de llum LED multicanal assequibles serà la tecnologia que permetrà un autentic canvi de paradigma espectral i començar a utilitzar la llum per a múltiples aplicacions. Aquest treball té com a objectiu facilitar aquesta transició proporcionant fonts de llum LED amb capacitat per generar qualsevol tipus de forma espectral. En una primera part, hem desenvolupat un sistema d'il·luminació multicanal orientat a un mercat d'investigació i recerca, i hem explorat nous dissenys i solucions per a un dispositiu més industrial amb l'objectiu de penetrar al mercat d'il·luminació general. Els dos esforços s'han materialitzat en dos dispositius òpticament i espectralment diferents: el sistema de llum SPECTRA TUNE LAB (amb un espectròmetre a l'interior i 10 canals LED diferents) i el sistema de llum VEGA 07 (amb un colorímetre i 7 canals LED diferents). En segon lloc, per poder crear qualsevol tipus de forma espectral, hem estudiat diferents algorismes heurístics implementats directament al micro-controlador de la lluminària o en un programari extern. L'algorisme desenvolupat de simulated annealing ha resultat ser el més ràpid amb una fidelitat espectral excel·lent. En tercer lloc, hem desenvolupat dos tipus de controladors òptics de llaç tancat amb dos sensors de llum diferents per evitar canvis de color i canvis espectrals degut a increments de la temperatura o degradació dels LEDs. Ambdós sensors, l'espectròmetre per l'SPECTRA TUNE LAB i el colorímetre pel VEGA 07, s'utilitzen per assegurar que la llum emesa romangui precisa i estable en tot moment, per a qualsevol espectre que vulguem generar. Finalment, demostrem com aquests dispositius es poden utilitzar per a diferents aplicacions oferint grans avantatges en comparació amb sistemes tradicionals. El nostre sistema d'il·luminació s'ha instal·lat a la unitat de cures intensives dhospitals (a l'Hospital Vall d'Hebron i a l'Hospital Clínic, a Barcelona), en entorns d'oficina (a ARUP, a Londres) o en sales de control 24 hores (a la sala de control de la refineria de Repsol, a Tarragona), entre d'altres

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2008.
Includes bibliographical references (p. 60).
In this thesis a low cost motion capture approach is presented and applied to measure cyclists' kinematics. The motion capture system consists of low cost hardware and custom developed software. Based on still-frame, off-the-shelf digital cameras, the method represents a solution which is accessible to the average athlete. With the exception of off-the-shelf digital cameras the total cost of the hardware is less than $100. The motion capture system is applied to study cyclist kinematics for three different types of bicycles: road bikes, triathlon bikes, and mountain bikes. Coupled with power output measurement and wind tunnel drag measurements, the investigation of several different standard cycling positions is performed. The results indicate a significant component of out-of- plane joint motions, especially in the knee, with an average knee excursion between 0.15" and 0.21". The system was also used to measure cycling cadence, with a range between 1.06Hz and 1.63Hz. Joint angle analysis suggested a positive correlation between ankle angle range and power output. Further in-depth analyses of these data or similar data collected using these motion capture approaches may give deeper insight into which motions correlate with higher power outputs. Wind tunnel and power data were used to calculate position transition velocities for different exertion levels and hill angles. This low-cost system was demonstrated to be a useful and effective tool for measuring and analyzing cycling kinematics.

Resumen
Dépistage du VIH, test de grossesse, mais également surveillance des eaux, détection de contaminants agro-alimentaires : la biodétection est au coeur des problématiques de santé actuelles. Dans ce contexte, les biocapteurs plasmoniques connaissent depuis quelques années un essor particulièrement important : de plus en plus de sociétés, telles que HORIBA Scientific, proposent des prototypes commerciaux, destinés tant à des utilisateurs du domaine de la recherche que de l'industrie. Basée sur le phénomène de résonance des plasmons de surface (communément appelé SPR) la biodétection plasmonique repose sur l'extrême sensibilité d’une onde évanescente se propageant à l’interface entre un film d’or, la biopuce, et le milieu diélectrique couvrant, siège des interactions biomoléculaires étudiées. De manière plus concrète, toute adsorption de matériel biologique se produisant à cette interface entraîne une modification importante des propriétés optiques d’un faisceau de lumière réfléchi par la biopuce : le principe de transduction par SPR consiste alors à mesurer directement ces variations. A l'heure actuelle, différents modes d'interrogation, offrant des performances intéressantes, mais également des limitations propres à chaque configuration. Pour répondre aux exigences de précision et de dynamique de mesure posées par de nombreuses applications, un développement théorique et instrumental, présenté dans ce document, a été initié dans le but de proposer un nouveau un nouveau mode d'interrogation des biopuces plasmoniques : l'interrogation multi-spectrale. Les résultats obtenus par cette technique ont été exploités pour concevoir et réaliser une source multi-spectrale à base de LEDs, particulièrement avantageuse vis-à-vis des configurations existant à l'heure actuelle. La caractérisation du système développé dans le cadre du diagnostic génétique (mucoviscidose) et celui du cancer, ouvre la voie à une nouvelle génération de biocapteurs performants, compacts et de coût relativement raisonnable, présentant un potentiel industriel certain
Biodetection is at the core of the current health concerns, as shown through the variety of applications to HIV screening, food contaminant analysis or water quality monitoring. In this field, plasmonic biosensing is a well-established label-free technique on the market: commercial systems from HORIBA Scientific are currently available for both research and industrial users.Based on the surface plasmon resonance (SPR) phenomenon, plasmonic biodetection uses the high sensitivity of an evanescent wave propagating along a metallic film (forming the biochip) and the surrounding dielectric medium interface. More specifically, the adsorption of biomolecules onto the metal surface induces a strong change in the optical properties of a light beam reflected by the biochip: the main principle of plasmonic transduction consists in measuring these physical changes. Several interrogation techniques have therefore been developed to access such optical information, but they fail in meeting the most demanding user requirements for precise, real-time, high-throughput measurement.Initiated by these issues, the instrumentation work presented in this document has led to the development of a novel SPR interrogation technique, referred to as multi-spectral interrogation. Moreover, the promising results obtained have been pushed forward to propose a multi-spectral illumination system based on LEDs, providing attractive performances compared to existing configurations. The biosensing potential of the developed system, demonstrated through applications to genetic diagnosis and cancer detection, opens the door to a new generation of compact, high-performance, low-cost SPR sensors

The aim of the present study was to evaluate the influence of different doses of energy and uni- or multi-wave LED units on mechanical properties of composite resins. Thereunto, six experimental groups were established for each assessed resin (IPS Empress Direct - Ivoclar Vivadent , Venus - Heraeus - Kulzer , SDR - Dentsply) according to the different different amounts of energy (5J , 10J and 20J) and LED unit (bluephase 16i and bluephase G2 - Ivoclar Vivadent) . Thirty six specimens were prepared (7mm long x 2mm wide x 1mm height) from silicon matrices and were used for evaluation of mechanical properties (flexural strength and modulus of elasticity) using the three points bending test, in a universal testing machine at a speed of 0.5 mm/min until the specimens fracture. Data were tested for normality and then the two-way analysis of variance was applied and Tukey's test was used to point out differences among means, with significance level set at 5%. Thus, the results showed that the resins presented different performance by energy amounts and by the difference of the spectra of light emitted by different sources. It appears from the data presented that the factors studied in this work are directly related to the mechanical properties of resin composites.
O objetivo do presente estudo foi avaliar a influência de diferentes doses de energia e unidades LED fotoativadoras de banda estreita e com amplo espectro nas propriedades mecânicas de resinas compostas. Para isso, 6 grupos experimentais foram estabelecidos para cada resina avaliada (IPS Empress Direct – Ivoclar Vivadent, Venus – Heraeus-Kulzer, SDR - Dentsply), de acordo com as diferentes doses de energia (5J; 10J e 20J) e unidades fotoativadoras (Bluephase 16i e Bluephase G2 – Ivoclar Vivadent). Trinta e seis corpos-de-prova foram confeccionados (7mm comprimento X 2mm largura X 1mm de altura) a partir de matrizes de silicone e foram utilizados para avaliação das propriedades mecânicas (resistência à flexão e módulo de elasticidade) utilizando o teste de flexão de três pontos, em máquina de ensaio universal a uma velocidade de 0,5 mm/min até que ocorresse a fratura do corpo-de-prova. Os dados foram avaliados quanto à sua normalidade e então, aplicado a Análise de Variância a dois critérios e teste de Tukey, com nível de significância fixado em 5%. Os resultados mostraram que as resinas apresentaram comportamentos diferentes entre si tanto pelas doses de energia utilizadas quanto pela diferença dos espectros de luz emitidos pelas diferentes fontes. Conclui-se dos dados apresentados que os fatores estudados neste trabalho têm relação direta com as propriedades mecânicas dos compósitos resinosos.

Resumen
Assessing the short-term socio-economic impacts of climate-led disasters on food trade networks requires new bottom-up models and vulnerability metrics rooted in complexity theory. Indeed, such shocks could generate cascading socio-economic losses across the networks layers where emerging agents¿ responses could trigger tipping points. We contribute to address this research gap by developing a multi-layer behavioral network methodology composed of multiple spatially-explicit layers populated by heterogeneous interacting agents. Then, by introducing a new multi-layer risk measure called vulnerability rank, or VRank, we quantify the stress in the aftermath of a shock. Our approach allows us to analyze both the supply- and the demand-side dimensions of the shock by quantifying short-term behavioral responses, the transmission channels across the layers, the conditions for reaching tipping points, and the feedback on macroeconomic indicators. By simulating a stylized two-layer supply-side production and demand-side household network model we find that, (i) socio-economic vulnerability to climate-led disasters is cyclical, (ii) the distribution of shocks depends critically on the network structure, and on the speed of supply-side and demand-side responses. Our results suggest that such a multi-layer framework could provide a comprehensive picture of how climate-led shocks cascade and how indirect losses can be measured. This is crucial to inform effective post-disaster policies aimed to build food trade network resilience to climate-led shocks, in particular in more agriculture-dependent bread-basket regions.

Resumen
Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current. This meant that the possibility of reactive power compensation was investigated to obtain lower thermal dissipation in dwarf signal. The essay presents a couple of possible solutions. One of the solutions is to raise the voltage by using a booster converter to use the existing 50V LED unit. Capacitors were reviewed to be used in reactive power compensation to increase current supply. One of the solutions then became a capacitor bank. Simulations indicated that a booster converter and a capacitor bank can be used to adapt the circuit. However, some modifications must be made.
Alstom ville undersöka möjligheten att anpassa sin lysdiodsteknik för dvärgsignaler i tågtrafiken. Lysdiodstekniken använder 50V men Alstom vill anpassa den för 12V. Lysdiodtekniken är strömsnål och behöver anpassas för befintliga signalställverk genom att dra en högre ström. Detta innebar att möjligheten för reaktiv kompensering undersöktes för att få en låg värmeutvecklingen i dvärgsignalen. I uppsatsen presenteras ett par möjliga lösningar. En av lösningarna för spänningen är en step-up omvandlare för att nyttja 50Vs enheten. Det gjordes också en genomgång av kondensatorer för att nyttjas i reaktivkompensering för att öka strömförbrukningen. En av lösningarna blev då ett kondensatorbatteri. Det kunde konstateras med matematisk simulering att step-up omvandlare och ett kondensatorbatteri kan användas för att anpassa kretsen dock måste vissa modifieringar utföras.

Resumen
Rebecca Whiting, Helen Roby, Gillian Symon, and Petros Chamakiotis develop an unconventional research design using video methods, asking participants to produce their own video diaries, a process which is then followed by narrative interviews. This approach generates multi-modal data: audio, visual, and textual, and involves adopting a qualitative perspective, and a social constructionist epistemology. This participant-led research design allows researchers to investigate a range of issues that are not often recalled in interviews or surveys, by capturing naturally occurring, real-time events and activities, and micro-interactions including non-verbal behaviours. Although video methods are used in other disciplines, they are rare in organizational research. The approach is illustrated by a study which explored how digital technologies affect our ability to manage switches across work-life boundaries. Analysis of participants’ video diaries illustrates the theoretical and reflexive insights that can be gained from this method. The problems and pitfalls encountered in this study are also considered.

Resumen
The research collaboration that led to the production of this book was supported by the TY Danjuma Fund for Law and Policy Development at the University of Cape Town. The primary collaboration between the Centre for Comparative Law in Africa (CCLA) at the University of Cape Town (UCT) and the Nigerian Institute of Advanced Legal Studies (NIALS) was established in 2014 as the CCLA–NIALS partnership—a fundamental term of the TY Danjuma endowment at UCT. The editors therefore express their gratitude to General TY Danjuma GCON for the generous and far-sighted support of this collaborative model of Africa-focused research. Indeed, African investment in collaborative and multi-disciplinary research such as this exemplifies the multi-stakeholder input that needs to foreground any meaningful intervention in Africa’s developmental issues, including the pervasive issue of energy access....

Resumen
Cancer is a disease of the genes. In the last two decades new technologies have allowed us to interrogate the genome more efficiently and faster. This has led to new therapies and improved understanding of cancers. It is clear the few cancers are caused by just one gene defect and in these rare cases the defective gene or its product is a target for therapeutic intervention. The bigger challenge now is to use this paradigm against multi-genic cancers which are far more common and more complex in their genetic makeup.

Resumen
Embryonal tumours account for 20% of paediatric central nervous system (CNS) tumours. Medulloblastoma (MB), the most frequent, arises in the cerebellum. Clinical strategies have been based on series of multi-institutional trials since the 1970s. Recent understanding of the influence of molecular/biological factors has led to subdivision into four distinct subtypes with differing clinical and prognostic profiles, on which stratification is now based. Management of MB in adults is largely based on principles of managing children, modified according to differing clinical and toxicity profiles. Molecular analysis has led to the understanding that what was previously referred to as CNS-PNET comprise a heterogeneous group of tumours with a significant proportion representing other histologies. Atypical teratoid/rhabdoid tumour (AT/RT) carries mutations in the gene hSNF5/INI1 in most cases, with many now associated with an improved prospect of long-term survival. Pineal tumours have similar clinical presentations, comprising a heterogeneous mix of histologies from pineocytoma through to pineoblastoma.

Resumen
Optimization techniques have played a vital role in improving the performance (i.e., input speed and accuracy) of soft keyboards. This chapter introduces the challenges, methodologies, and results of keyboard performance optimization. Leveraging the robust human motor control phenomena manifested in text entry, we used the Metropolis random walk algorithm, and Pareto multi-objective optimization method to optimize the keyboard layout and a soft keyboard decoder. The optimization led to layouts that shorten finger travel distance and improve the input speed as well as accuracy over the Qwerty layout, and a soft keyboard decoder with improved correction and completion ability.

Resumen
This chapter provides the first detailed survey of the multi-author work, led by Jean Jaurès, to write a socialist history of modern France. It explores the specific context in which the work was produced, restoring the intellectual networks and personal connections that made the project possible, and then focuses in particular on the way Jaurès’ collaborators wrote about the social movement from the 1790s to 1900. There was a concern through most of the volumes to try and understand the flow of time in the nineteenth century as being different from that of the twentieth century; the socialist historians wanted to mark their own era as being different to that of the revolution, but also thereby to recapture the moments of past injustice and suffering in a popular, widely read narrative.

Herbert, Sian. Reducing Criminal Violence Through Public Sector-led Multisectoral Approaches. Institute of Development Studies, octubre de 2021. http://dx.doi.org/10.19088/k4d.2022.043.

Texto completo
Resumen
The last decades have seen increased consensus for the need to understand and address violence through a public health approach, and a preventative approach, as embodied by Sustainable Development Goal (SDG) 16. This necessitates a multi-sector and multi-stakeholder approach, yet poor governance continues to threaten progress on this agenda. Many policy approaches to urban violence tend to take an approach that is either place-based; people-based; or behaviour-based and include a range of initiatives. The INSPIRE initiative is a key global response to tackling violence against women (VAW) and violence against children (VAC) A multisector approach is needed to address the complexity and multifactorial origins of violence. Yet multisector engagement can complicate institutional responses due to different goals, concepts, instruments, etc. Increased collaboration and joined-up approaches across government departments have led to changes in institutions and approaches. The literature base on violence prevention initiatives is varied and uneven across the different types of violence, e.g. with more literature available on interventions focussed on interpersonal and urban violence compared to organised crime-related violence. Evaluations are limited and face many methodological challenges (Cuesta & Alda, 2021) – e.g. the scale and complexity of violence limits the extent to which interventions can be rigorously evaluated or comparable, and most focus on interventions in the Global North. Most importantly, the literature base for this specific question – focussed on the wider institutional context and lessons for a multisectoral approach – is very limited, as most of the available literature focusses on lessons relating to the outcomes of the interventions. In line with the operational focus of this paper, this review draws mainly on practitioner and policy publications. The approaches, interventions, and lessons detailed below are illustrative and are not comprehensive of the many complex lessons relating to this broad area of programming.

Texto completo
Resumen
Shia account for approximately 10–15 per cent of the Muslim population in Pakistan, which has a largely Sunni Muslim population. Anti-Shia violence, led by extremist militant groups, dates to 1979 and has resulted in thousands killed and injured in terrorist attacks over the years. Hazara Shia, who are both an ethnic and a religious minority, make an easy target for extremist groups as they are physically distinctive. The majority live in Quetta, the provincial capital of Balochistan in central Pakistan, where they have become largely ghettoised into two areas as result of ongoing attacks. Studies on the Hazara Shia persecution have mostly focused on the killings of Hazara men and paid little attention to the nature and impact of religious persecution of Shias on Hazara women. Poor Hazara women in particular face multi-layered marginalisation, due to the intersection of their gender, religious-ethnic affiliation and class, and face limited opportunities in education and jobs, restricted mobility, mental and psychological health issues, and gender-based discrimination.

Texto completo
Resumen
This paper explores post-Nazarbayev state-building in Kazakhstan, focusing on domestic and foreign policy implications of the power transition. After thirty years of incumbency, President Nursultan Nazarbayev stepped down in 2019, smoothly transferring the power to his nominee, Kassym-Jomart Tokayev, and thus plunged the country into a sensitive phase of power transition. This study suggests that the power transition in Kazakhstan has not led to significant improvements in terms of human rights and political freedoms protection, leaving the state of the weak opposition and constrained civil society intact. Kazakhstan keeps maintaining the core features of oil-rich countries, with hydrocarbon-based economy and regime stability stemming from an “authoritarian bargain” between the state and society. Besides, there has been continuity in foreign policy, with Kazakhstan further pursuing a multi-vectoral foreign policy agenda.

This Evidence Check commissioned by NSW Ministry of Health aimed to evaluate delivery of physical health interventions for people living with a mental illness, delivered though community mental health programs. The review found that sufficient evidence exists to support a number of interventions, with further evaluation; and identified and describes key characteristics for effectiveness such as duration of the intervention and mode of delivery (e.g. face-to-face or telephone, group or individual). The supported interventions and/or actions included: multi-strategy lifestyle behaviour change interventions; care delivery models including peer-led self-management and staff delivered interventions; integration of new physical health care models or initiatives; referral to other services (e.g. telephone Quitline); assessing barriers and enablers prior to implementation; and the involvement of peer workers and consumers in design and delivery.

Texto completo
Resumen
This report critically examines the nature of the distinction between traditional inter-state diplomacy and sustainable development diplomacy. It then sets out the institutional changes which are necessary for the achievement of sustainable development diplomacy. Multi-stakeholder partnerships have been identified as a key means of implementation for the Sustainable Development Goals (SDGs). Given the increasing centrality of the United States (US)–China relationship in global development cooperation, understanding the modalities of their engagement may provide useful insights into how partnerships may be cultivated and deepened to realise the SDGs. The Covid-19 pandemic and climate change have demonstrated the interconnection of the world, as well as the interconnection of challenges of the world. Sustainable development diplomacy is needed now more than ever to prioritise development strategies of different states and work on common shared challenges. Sustainable development diplomacy can only work when different actors recognise the value of the common goals and are willing to make an effort to accomplish them. Global sustainable development diplomacy requires a stronger policy agenda and greater cohesion. This report explores the idea of sustainable development diplomacy and, through two sectoral case studies, explores the nature, function, and rationale for interactive engagement. The form and structure of multi-actor relationships are a response to complex, trans-border political, social, economic, and environmental challenges which require a more nuanced and varied management approach than narrowly defined state-led development. However, the power dynamics, the modalities, and experiences of engagement that underpin these dynamic relationships, remain understudied, especially with regard to their impact on sustainable development.

Texto completo
Resumen
Diamond mining via open pit mining has been ongoing within the Tlicho region of the Northwest Territories for several decades, which includes the habitat range of the Bathurst Caribou Herd. This has led to the importance of quantitative characterization of the Zone Of Influence (ZOI), where resource development activities may be influencing the natural behaviour of the caribou herd in the tundra environment. As part of better defining and understanding the ZOI in this region, an initiative to evaluate the potential of detecting and mapping mine waste rock dust in the surrounding environment is explored. This dust has been shown to coat foliage near roads, influencing the acidity levels of the surficial soil layer and impacting the foliage distribution. To this end, field spectrometry was acquired at various distances from road ways. Satellite imagery from the Proba-1 CHRIS hyperspectral sensor and the multi-spectral Sentinel-2a system were also acquired of the region. This presentation presents the initial spectral analysis pursued to evaluate the potential to remotely spectrally detect waste rock dust material used in road construction in the surrounding tundra vegetation. Initial analysis of the Proba-1 CHRIS hyperspectral imagery shows spectral indicators of fugitive dust and waste rock easily detects the road and suggests detectable dust concentration above ambient up to a distance of under 1km from the road.

Texto completo
Resumen
Despite growing interest and recognition of urban and peri-urban agriculture (UPA) as a nature- based solution, there is limited empirical evidence in countries like India on its role in reconfiguring goals on environmental functions (such as biodiversity, waste management, water recycling, micro-climate regulation, etc.) and social wellbeing (such as food and nutrition security, gender relations, work burdens, land tenure and community ties). A need to address this gap led to the ideation of the project ‘Urban and peri-urban agriculture as green infrastructures’ ( UPAGrI ). When UPAGrI started in 2019, the research on UPA in India was thin but growing. However, the practical experience of urban farming across Indian cities is thriving and diverse, built on decades of bottom-up experimentation. Within the landscape of our ever-changing cities, we found vibrant communities-of-practice sharing seeds and knowledge, engaged online influencers discussing composting and water reuse, and stories of farming becoming sites of multi-generational bonding and nutritional security. This compendium is a collection of 29 such innovative UPA practices from across the different cities in the country. These diverse case studies are loosely categorized into four themes: environment and sustainability; food, nutrition and livelihood; gender and subjective well-being; and urban policy and planning. Written mostly by practitioners themselves, the case studies collectively recognise and celebrate UPA innovations and practices, serving as a repository of lessons for peer-to-peer learning, and demonstrating how UPA can be one of the many solutions towards sustainable, liveable Indian cities.
