An Introduction to Information Retrieval

Abstract: Information retrieval is a discipline that deals with the representation, storage, organization, and access to information items. The goal of information retrieval is to obtain information that might be useful or relevant to the user: library card cabinets are a “traditional” information retrieval system, and, in some sense, even searching for a visiting card in your pocket to find out a colleague’s contact details might be considered as an information retrieval task. In this chapter we introduce information retrieval as a scientific discipline, providing a formal characterization centered on the notion of relevance. We touch on some of its challenges and classic applications and then dedicate a section to its main evaluation criteria: precision and recall.

The organizational dynamics of Enterprise Risk Management

Abstract: This paper explores the organizational dynamics of Enterprise Risk Management (ERM). ERM is the main form taken by firms’ increasing efforts to organize uncertainty, which ‘exploded’ in the 1990s. The ERM approach seeks to link risk management with business strategy and objective-setting, entering the domains of control, accountability and decision making. In this work, the organizational variations of ERM are investigated through a longitudinal multiple case study, using data from three companies collected over a 7-year period (from 2002 to 2008). The findings contribute to our understanding of ERM as a practice, revealing its trajectory within the organizations as it encounters pre-existing logics, and as both are shaped by risk rationalities, experts and technologies.

Geographies of resilience Challenges and opportunities of a descriptive concept

Abstract: In disaster science, policy and practice, the transition of resilience from a descriptive concept to a normative agenda provides challenges and opportunities This paper argues that both are needed to increase resilience We briefly outline the concept and several recent international resilience-building efforts to elucidate critical questions and less-discussed issues We highlight the need to move resilience thinking forward by emphasizing structural social-political processes, acknowledging and acting on differences between ecosystems and societies, and looking beyond the quantitative streamlining of resilience into one index Instead of imposing a technical-reductionist framework, we suggest a starting basis of integrating different knowledge types and experiences to generate scientifically reliable, context-appropriate and socially robust resilience-building activities

Rectifiability and perimeter in the Heisenberg group

Abstract: In this paper, we fully extend to the Heisenberg group endowed with its intrinsic Carnot-Caratheodory metric and perimeter the classical De Giorgi's rectifiability divergence theorems.
