CCTV as a Socio-technology

The authors discuss CCTV, which is now established as a mature and ubiquitous technology. They review existing research on CCTV as backdrop to introduce an alternative re-narration that stresses its use as an advanced information technology—a socio-technology. Central to this perspective is the recognition that system effectiveness hinges on a match of individual, organizational and technological

European Stabilization Policy After the Covid-19 Pandemic: More Flexible Integration or More Federalism?

Crises are a major driving force behind cooperation in the European Union. This holds also for monetary and fiscal policy. During severe crises, cooperation has been enlarged and intensified. The recent covid-19 pandemic is a clear example of this pattern. The pandemic has had huge impact on the conduct of stabilization policies in the EU. Public debt has grown rapidly in many EU member states. Th

AI policy in Poland : Ethical considerations already at the core

The chapter outlines the main stages of development of AI strategy in Poland, focusing on three significant documents: Considerationsfor AI Strategy in Poland (November 2018), Policy for Development of AIin Poland for the years 2019-2027 (August 2019) and the draft Policy forDevelopment of AI in Poland from year 2020 (September 2020). At themoment of writing, the latter document has been adopted b

Numerical investigation of railway subgrade stiffening : Critical speed and free-field vibrations

For a train speed close to the speed of elastic waves in the soil, often referred to as “critical speed”, largely elevated vibration responses occur. This can be a practical problem for soft soil sites, where the phenomenon may cause excessive vibrations in the track and also at distances far from the track. To ensure the running safety of the train, the long-term quality of the track and to reduc

The effect of constitutive representations and structural constituents of ligaments on knee joint mechanics

Ligaments provide stability to the human knee joint and play an essential role in restraining motion during daily activities. Compression-tension nonlinearity is a well-known characteristic of ligaments. Moreover, simpler material representations without this feature might give reasonable results because ligaments are primarily in tension during loading. However, the biomechanical role of differen

Persisting breathlessness and activities reduced or ceased: a population study in older men

Introduction Breathlessness is debilitating and increases in prevalence with age, with people progressively reducing their everyday activities to ‘self-manage’ it. This study aimed to evaluate the impact of breathlessness on function in terms of activities that have been reduced or ceased (‘compromised’) in older men.Methods A cross-sectional postal survey of Swedish 73-year-old man in the VAScula

Purse of medieval silver coins from royal shipwreck revealed by X-ray microscale Computed Tomography (µCT) scanning

We present the archaeological discovery and microscale X-ray Computed Tomography (µCT) scanning of a silver coin purse lost in a medieval shipwreck while the king who issued many of the coins was aboard. The find demonstrates that shipwrecks are extraordinary repositories of historical information, in this case providing insight into one of the most important and dramatic events of medieval Scandi

Diclofenac for acute postoperative pain in children

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the efficacy and safety of diclofenac (any dose) for acute postoperative pain management in children compared with placebo, other active comparators, or diclofenac administered by either different routes (e.g. oral, rectal, etc.) or strategies (e.g. as needed versus as scheduled).

Using Metrics of a Mixture Effect and Nutrition from an Observational Study for Consideration towards Causal Inference

Environmental exposures to a myriad of chemicals are associated with adverse health effects in humans, while good nutrition is associated with improved health. Single chemical in vivo and in vitro studies demonstrate causal links between the chemicals and outcomes, but such studies do not represent human exposure to environmental mixtures. One way of summarizing the effect of the joint action of c
