Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes

2022

Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021. Results…

The Reconstruction of Production and Storage Sites for Chemical Warfare Agents and Weapons from Both World Wars in the Context of Assessing Former Mu…

2017

This chapter begins by listing the quantities and sites of chemical agent production during both world wars and outlining the relative importance of these new weapons. Using the example of the production sites of World War II, the setting in which the construction and operation of these factories took place will be described, as well as the structure of the facilities. It will be shown that it was not only Fritz Haber’s former colleagues who made important contributions to the research of chemical warfare agents and their production, but that an important role was also played by students of his successor at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry. In order t…

UMTS radio networks

2006

Publisher Summary This chapter reviews the contributions to the UMTS radio network planning, with the optimization being provided from COST 273 and the real-time tuning, which is related to RRM. The results on UTRAN performance evaluation by the means of simulation tools are also discussed. The UMTS planning includes processes like: the propagation and traffic models, the aspects of parameter planning, and the automatic planning algorithms. An accurate ray-tracing model integrated in a UMTS-capable planning tool allows the radio network planner to reach optimal numbers for the BS deployment and configuration while meeting the service level requirements. Ray tracing can identify the problem …

Large Scale Control of Deferrable Domestic Loads in Smart Grids

2016

International audience; In this paper, we investigate a realistic and low-cost deployment of large scale direct control of inelastic home appliances whose energy demand cannot be shaped, but simply deferred. The idea is to exploit 1) some simple actuators to be placed on the electric plugs for connecting or disconnecting appliances with heterogeneous control interfaces, including non-smart appliances, and 2) the Internet connections of customers for transporting the activation requests from the actuators to a centralized controller. Our solution requires no interaction with home users: in particular, it does not require them to express their energy demand in advance. A queuing theory model …

Information Ecology as a holistic lens to understand ICTD initiatives

2016

Techno-centric initiatives to bridge the digital divide, such as One Laptop per Child (OLPC), has been criticized for not taking a holistic approach. This has led to limited success in areas such as providing quality education in developing countries. In this paper, we offer a premise for a holistic understanding by borrowing from the field of information ecology. To illustrate our premise, we applied the theoretical lens of information ecology to analyze a case study of Open Learning Exchange (OLE) which has been described as one of the few successes in implementing OLPC. Based on our analysis, we posit that information ecology is a suitable and appropriate lens to interpret and understand…

PASSI: Process for Agent Societies Specification and Implementation

2014

PASSI (a Process for Agent Societies Specification and Implementation) is a step-by-step requirement-to-code methodology for designing and developing multiagent societies, integrating design models and concepts from both Object-Oriented software engineering and artificial intelligence approaches using the UML notation. The models and phases of PASSI encompass anthropomorphic representation of system requirements, social viewpoint, solution architecture, code production and reuse, and deployment configuration supporting mobility of agents. PASSI is made up of five models, concerning different design levels, and 12 activities performed to build multiagent systems. In PASSI, the UML notation i…

The SADC Standby Force and Its Regional Peacekeeping Training Centre: Uncertain Operational Readiness and Future of an Externally Fuelled Brigade

2017

This chapter offers a comprehensive explanation of why and how SADC countries engaged in military integration and put efforts in establishing a regional standby brigade with an associated peacekeeping training centre. This chapter pays special attention to the impact of extra-regional actors and donors’ funding in this regard since the development of the SADC Standby Force occurs at a time when the region lacks an actual external threat. Instead, the African Union, together with the EU, provides financial incentives and thus promotes the build-up of a SADC brigade. The EU’s external influence, however, has been ambivalent insofar as a freezing of donations paralysed the operational capacity…

Problems in the interplay of development and IT operations in system development projects: A Delphi study of Norwegian IT experts

2011

ContextThe assumption of the presented work is that the ability of system developers and IT operations personnel to cooperate effectively in system development projects has great impact on the quality of the final system solution, as well as on the service level of its subsequent operation. ObjectiveThe present research explores the interplay of system development and IT operations and the challenges they are meeting. We are especially interested in identifying problems encountered between these two parties in system development projects. MethodWe identify and rank problems by using a ranking-type Delphi study. We involved 42 Norwegian IT experts and split them into three expert panels: sys…

Strategic Priorities and Lean Manufacturing Practices in Automotive Suppliers. Ten Years After

2011

Currently, automobile manufacturers have transformed their philosophy of production in favour of the lean manufacturing paradigm. By doing so, they hope to improve efficiency and to obtain better results in the markets in which they operate. This transformation must occur not only in their plants, but it seems important that their suppliers should also modify their production systems in line with the lean manufacturing philosophy (Liker & Wu, 2000; Morris et al., 2006; Oliver & Delbridge, 2002). The effects of this wave will probably result that one integrated supply chain can be built. Supply companies can see benefits from the implantation of lean manufacturing practices in certain of the…
