The Evolution of Physical Security and Stockpile Management: A Successful Implementing Partnership Perspective

To avoid unplanned explosion of munitions (UEM) and to lower the risk of illicit diversion, the humanitarian requirements ensuring strong ammunition management structures, systems, and processes by states have been well documented in past issues of this Journal and other publications. These needs have led to the evolution of multilateral and bilateral support from donor nations that see the humanitarian value of supporting physical security and stockpile management (PSSM)

Habilidades sociales y logros de aprendizaje en estudiantes de secundaria de la institución educativa privada guía divina, Ventanilla – 2022

El presente estudio tuvo por objetivo establecer la relación entre las habilidades sociales y logros de aprendizaje en estudiantes de secundaria de la IEP Guía Divina, Ventanilla - 2022; siguiendo un enfoque cuantitativo, no experimental, descriptivo-correlaciona en base a dos cuestionarios para una muestra de 82 estudiantes (total 103). En los resultados descriptivos, para las habilidades sociales fueron 67% (media), 18% (baja), y 15%; mientras que, para los logros de aprendizaje el 63% (destacado), 26% (destacado), y 11% (inicio). En los inferenciales, en el cruce de habilidades sociales y logros de aprendizaje se calculó Sig.= 0.000 y R=0.829, donde alrededor de las tres partes cuartas partes de los estudiantes (74.4%) se corresponden con los niveles bajos e intermedios de las habilidades con los niveles de inicio y regular de los logros, y el restante (25.6%) en los niveles más afirmativos de ambas, evidenciándose dificultades en los comportamientos inadecuados percibidos en determinadas situaciones como respetar a los demás, solucionar problemas inmediatos y minimizar su ocurrencia; y no teniendo consolidados los factores vinculados a la escuela y al propio individuo referidos al alcance adecuado en el aprendizaje. Para los cruces de las dimensiones de las habilidades sociales con los logros de aprendizaje, también se encontró que asociación positiva y moderadamente alta. Concluyéndose que, la relación es alta, positiva y significativa entre las habilidades sociales y los logros de aprendizaje en estudiantes de secundaria de la IEP Guía Divina, Ventanilla - 2022.TesisComunicación y desarrollo human

Central Bank Digital Currencies

Today’s societal digitization continues to advance at exponential speeds driven by technology trends. Billions of Internet of Things devices have made their way into our daily lives, but also into healthcare, manufacturing, and supply chains. In contrast, the financial sector still largely operates on legacy infrastructures, where merchants receive their payments long after they released the digital/physical good to the consumer. In addition, the emergence of Decentralized Finance through blockchain technology, and the accumulation of data in private silos, have demonstrated a capacity to impact national sovereignty and monetary transmission channels. Against this backdrop, many central banks have recently started to research and test the issuance of digitally native fiat money – or Central Bank Digital Currencies (CBDCs) – in an effort to redesign the essence and use of physical cash. CBDCs present a broad variety of designs, which translate into manifold techno-legal and standardization policy questions. In this context, this chapter surveys the state-of-the art with specific focus on “retail” CBDCs. In doing so, it provides an overview of candidate architectures, heeds legal impacts and regulatory compliance issues, presents a set of case-studies and touches upon cross-border CBDC challenges

Cost-effective blockchain-based IoT data marketplaces with a credit invariant

Billions of Internet of Things (IoT) devices deployed today collect massive amounts of potentially valuable data. To efficiently utilize this data, markets must be developed where data can be traded in real time. Blockchain technology offers a potential platform for these types of markets. However, previous proposals using blockchain technology either require trusted third parties such as data brokers, or necessitate a large number of on-chain transactions to operate, incurring excessive overhead costs. This paper proposes a trustless data trading system that minimizes both the risk of fraud and the number of transactions performed on chain. In this system, data producers and consumers come to binding agreements while trading data off chain and they only settle on chain when a deposit or withdrawal of funds is required. A credit mechanism is also developed to further reduce the incurred fees. Additionally, the proposed marketplace is benchmarked on a private Ethereum network running on a lab-scale testbed and the proposed credit system is simulated so to analyze its risks and benefits
