Theories of Change in Global Health

Theories of Change in Global Health

Stephen Luby; Sabina Faiz Rashid

OXFORD UNIVERSITY PRESS INC
2026
nidottu
Global health interventions aim to improve health in communities. Underlying each intervention is a theory of change that addresses a specific constraint--such as poverty, limited access to clinical care, or weak governance--within the complex system that shapes global health. Theories of change can help explain broad global improvements such as those in life expectancy and child mortality. They can also be used to develop interventions for communities facing serious health problems. As global health problems are complex, different definitions of underlying constraints are often championed by different disciplines. Economists generally favor approaches that address poverty or economic instability; physicians advocate for improved health systems; engineers favor investment in technology; charities emphasize the importance of aid. However, monodisciplinary approaches ignore the complex systems that generate global health problems and omit a consideration of the strengths and weaknesses of potential interventions. In Theories of Change in Global Health, Stephen Luby and Sabina Faiz Rashid critically evaluate fifteen common theories of change that underlay global health interventions. Through case studies and examples of interventions across contexts, Luby and Rashid develop a framework of the conditions under which different theories of change have been successful and the conditions which predispose a particular theory of change to failure. As they argue, no single theory of change is a panacea. By spotlighting the often-implicit theory of change and underlying problem definition, this book aims to improve the specificity, depth, and effectiveness of interdisciplinary conversations around optimal strategies towards global health improvement. It also provides critical guidance about which theories of change are most promising and encourages stakeholders to broaden the range of possible interventions under consideration.

Re-treatodontics

pokkari
This book summarizes about practices being conducted in clinical endodontics in such a way that successful endodontic treatment should never be guaranteed to a patient in cases of retreatment but a higher degree of success should always be expected. Therefore, retreatment is like the repair of an old building which has to be accomplished with utmost care and precision to achieve a positive result should be the goal

UAV zur Minensuche

UAV zur Minensuche

Amna Ziauddin; Saad Ur Rehman Faiz

Verlag Unser Wissen

pokkari
Um sich vor Sprengstoffen wie Minen und USBVs zu sch tzen, muss man einen sicheren Abstand einhalten. Wir besprechen hier das Konzept eines Metalldetektors f r Minen, der auf einem Quadrocopter montiert ist, der als unbemanntes Luftfahrzeug (UAV) eingesetzt wird. So kann eine Person den Sprengstoff aus sicherer Entfernung erkennen und zur Detonation bringen, wodurch das Risiko minimiert wird. Das UAV erm glicht auch die Erkundung der Umgebung, indem es ein Video an die Person sendet, die es steuert.

Pour se prot ger des explosifs tels que les mines et les engins explosifs improvis s, il faut maintenir une distance de s curit . Nous examinons ici le concept d'un d tecteur de mines m talliques mont sur un quadcopt re utilis comme v hicule a rien sans pilote (UAV). Cela permet une personne de d tecter et de faire d toner l'explosif partir d'une distance de s curit minimisant le risque. Le drone permet galement la reconnaissance d'une zone environnante en transmettant une vid o la personne qui le contr le.

Per garantire la sicurezza da esplosivi come mine e ordigni esplosivi improvvisati necessario mantenere una distanza di sicurezza. Qui discutiamo il concetto di un rilevatore di mine metalliche montato su un quadricottero, che viene utilizzato come veicolo aereo senza pilota (UAV). Ci consente a una persona di rilevare e far esplodere l'esplosivo da una distanza di sicurezza, riducendo al minimo il rischio. L'UAV consente anche la ricognizione di un'area circostante, trasmettendo un video alla persona che lo controlla.

Magnetic Field Assisted Finishing

Magnetic Field Assisted Finishing

Dilshad Ahmad Khan; Zafar Alam; Faiz Iqbal

CRC Press
2021
sidottu
This comprehensive reference text discusses the concepts of the magnetic field assisted finishing processes that range from working principles, material removal mechanisms, process parameters and equipment involved, to the industry-specific applications.The book discusses various aspects of surface finishing, including types of material to be finished, types of finishing abrasives and their characteristics for material compatibility, that are different from process-specific details. It covers important concepts, including magnetic abrasive finishing (MAF), magnetorheological finishing (MRF) and magnetorheological abrasive flow finishing (MRAFF).FeaturesDiscusses a wide range of magnetic field assisted finishing processes in a comprehensive mannerCovers different process parameters by considering their effects on the finishing outputProvides process limitations to achieve optimal yieldOffers numerical explanations for better selection of process parametersDiscusses automation of processes with state-of-the-art technologiesThis book is aimed at graduate students and professionals in the fields of mechanical engineering, aerospace engineering, production engineering, manufacturing and industrial engineering.
