An Initial Security Analysis of the Personal Transaction Protocol
2003
Our society is becoming increasingly dependent on the rapid access and processing of information. The number of handheld mobile devices with access to the Internet and network-based software and services is exploding. Research indicates [1] that by the end of 2002 there will be over 1 billion mobile phone owners globally with Internet access, and that this number is going to grow exponentially in the nearest future. By 2006 the number of interconnected mobile device users is expected exceed the worldwide Internet subscriber population. It is estimated that in a few years there will be three times as many of these devices worldwide as personal computers.
Drones in cyber security environment
2019
Aerial unmanned vehicles (AUV) are currently used for a wide range of operations such as border surveillance, surveillance, reconnaissance, transport, aerial photography, traffic control, earth observation, communications, broadcasting and armed attacks. AUVs are presumed to be reliable, automated and autonomous machines. AUVs are extremely suitable for long missions that strain flight crews or put them to harm's way. Two advantages can be gained by eliminating the flight crew: 1) performance improves (range, endurance, increased payload and maneuverability, smaller physical size and lower observability) and; 2) the ability to take higher risks. UAV/RPAS/drone cyber security has largely foc…
Food Security Is None Of Your Business? Food Supply Chain Management In Support Of A Sustainable Food System
2017
Food security is the principal outcome of any given food system and it can be defined in terms of a sustainable food system where the core goal is to feed everyone sustainably, equitably and healthily. A sustainable food system addresses needs for availability, affordability and accessibility, is diverse, ecologically-sound and resilient, and builds the capabilities and skills necessary for future generations. This paper identifies the essential elements of food supply chain management in support of a sustainable food system, which ultimately enhances food security. The existing food supply chain and food system literature is synthesized in order to study the correspondence between public i…
Justice in transitions: Widening considerations of justice in dietary transition
2021
Just transition is gaining increasing attention. The need to consider social justice in sustainability transitions is finally being acknowledged. Research on this issue has, to date, mainly concentrated on energy systems. In this paper, we examine how the elaboration of dietary transition widens the spectrum of justice questions in sustainability transitions research. We explicate the arising normative questions along the dimensions of distributive, procedural and recognitive justice; widening the considerations further to restorative and cosmopolitan justice. Dietary transition widens the justice considerations to basic needs, food security and nutrition. By doing so, it evokes socio-cultu…
O tak zwanym szpiegu i terroryście koronnym
2017
The subject of this article is the authorization of intelligence services in preventing and combating the offences of espionage and terrorism. It describes the regulations of the Second Polish Republic regarding espionage, a draft Act on Intelligence Activities, the rule of law and opportunism, and most importantly new regulations under the anti-terrorism law
Faith- based diplomacy and cultural security: Between pluralism and particularism
2023
Two basic approaches to faith-based diplomacy (FBD) have developed over the last twenty years. For some, it is a synonym of supra-denominational conflict prevention and resolution, and for others, it is an element of the state’s foreign policy exploited to achieve not just cultural but also political goals. The purpose of the chapter is to present the interrelationships between FBD and cultural security in the context of the “return of religion” and the “post-secular turn”. The conducted analysis, which is theoretical in nature, contributes to the discussion on the role of the religious determinant, pointing to the existence of two fundamentally separate approaches to the application of rel…
A cost efficiency analysis of flood proofing measures for hydraulic risk mitigation in an Urbanized riverine area
2020
Non-structural measures for flood risk mitigation are often more economically accessible, easier to implement, and are highly effective, especially in view of the pursuit of risk resilience objectives. Among the non-structural measures, more importance is increasingly being attributed to flood proofing interventions. There are two main types of flood proofing: dry proofing and wet proofing. An example of dry proofing is shielding, which involves the use of flood barriers that can be installed in the entrances of buildings or outside the buildings in order to avoid contact with the houses and deviate the water flow. Their use must be supported by a detailed hydraulic analysis to ensure the c…
Italian Consumers’ Preferences for Pasta and Consumption Trends: Tradition or Innovation?
2019
The aim of this study is to know Italian consumers’ preferences for Pasta and consumption habits. Food culture and concerns about food security and product innovation were investigated. A sample of Italian consumers was interviewed. Consumer’ profile, motivations and purchasing behavior were described. Relationships between observed variables and the latent constructs that explain the preferences were highlighted. There is asymmetric information between consumers and producers. Consumers believe Pasta is made with Italian grains, and therefore it is healthy and safe, although that’s not always the case. Intrinsic and extrinsic high quality, which derives from growing and production technolo…
Agri-Food Markets towards Sustainable Patterns
2020
In recent decades, the confluence of different global and domestic drivers has led to progressive and unpredictable changes in the functioning and structure of agri-food markets worldwide. Given the unsustainability of the current agri-food production, processing, distribution and consumption patterns, and the inadequate governance of the whole food system, the transition to sustainable agriculture and food systems has become crucial to effectively manage a global agri-food market able in supporting expected population growth and ensuring universal access to sufficient, safe, and nutritious food for all. Based on a critical review of the existing international literature, the paper seeks to…
Determining nanomaterials in food
2011
Abstract Nanotechnology has emerged as one of the most innovative technologies and has the potential to improve food quality and safety. However, there are a few studies demonstrating that nanomaterials (NMs) are not inherently benign. This review highlights some current applications of NMs in food, food additives and food-contact materials, and reviews analytical approaches suitable to address food-safety issues related to nanotechnology. We start with a preliminary discussion on the current regulatory situation with respect to nanotechnology in relation to foods. We cover sample preparation, imaging techniques (e.g., electron microscopy, scanning electron microscopy and X-ray microscopy),…
