Monetary Policy and Economic Performance in Resource Dependent Economies - Ba...Economic Research Forum

ERF and AFESD Conference
Monetary and Fiscal Institutions in Resource-Rich Arab Economies
Kuwait, November 4-5, 2015
For more info, please visit www.erf.org.eg
Session on: Resource Abundance, Fiscal Dominance and Monetary Outcomes
While monetary policy could play a key role in fostering economic growth and short-term stabilization, its implementation in oil rich economies is often complicated by commodity price volatility. This session explores the role of alternative monetary policy regimes on economic performance in resource-based economies, with a particular focus on Arab economies. It also examines the interdependence between fiscal and monetary policies in resource-dependent economies, in particular the fiscal drivers of the choice of the exchange rate regime.
GCC Currency Union: Necessary Precursors and Prospects - Emilie J. RutledgeEconomic Research Forum
Emilie J. Rutledge, United Arab Emirates University
ERF and AFESD conference on: Monetary and Fiscal Institutions in Resource-Rich Arab Economies
Kuwait, November 4-5, 2015
For more info, please visit www.erf.org.eg
Session on: Central Bank Independence and Institutional Reforms
Optimal monetary policy response to commodity price shocks requires the presence of credible and strong institutions, which are often absent in resource-rich Arab economies. It also requires clarity about central bank versus government objectives and clear institutional arrangements about the role of each. Among the ways to achieve credibility and instill a clear division of policy responsibilities is to promote central bank independence (CBI). This section aims to examine the independence of monetary institutions in several Arab resource-rich economies as well as other institutional reform required for an effective and well-functioning GCC currency union.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
