Abstract

El periodismo deportivo se ha caracterizado por una serie de deficiencias éticas que han soslayado los estándares normativos de la profesión. Los instrumentos de rendición de cuentas pueden jugar un papel valioso para superar estas disfunciones. Teniendo esto en mente, el artículo identifica y examina los mecanismos de rendición de cuentas más relevantes en el ámbito del periodismo deportivo, incluidos aquellos producidos de forma interna y externa a los medios. Los investigadores han inspeccionado los códigos éticos en esta área, los libros de estilo promovidos por los principales medios deportivos y las prescripciones formuladas por las agencias informativas, medios de información generalistas y organismos clave a nivel internacional. Prácticas innovadoras como los chats, redes sociales, defensores del lector en línea, observatorios y blogs también se han identificado como ejemplos positivos del cultivo de una conversación bidireccional sobre los estándares y la calidad de los contenidos deportivos. AbstractSports journalism has been characterized by a series of ethical deficiencies that have challenged the normative standards of the profession. Media accountability instruments can play an invaluable role in addressing these shortcomings. With this in mind, this article identifies and examines the most relevant accountability instruments in the field of sports journalism, including those produced within media organizations and those created outside of them. The researchers have scrutinized the specialized codes in this area and the stylebooks promoted by major sports media, as well as the recommendations proposed by news agencies, general information outlets and key stakeholders worldwide. Innovative practices such as chats, social media, online ombudsmen, observatories and blogs have also been identified as positive examples of the cultivation of a two-way conversation about the standards for and quality of sports content.

Abstract

The modern society's increasing mobility is placing a growing demand on traffic safety. An important way to meet this demand will be offered by on-board driver assistance systems. Introducing inter-vehicle communication allows these systems to use traffic data collected by other vehicles. This opens up the possibility to implement co-operative driving behaviour thereby improving the overall traffic safety. This idea is formalised in an advanced driver assistance concept called Mensor. In this concept the actions of multiple drivers are measured and combined into a 'safety state' indicating the 'level of traffic safety'. The safety state message is sent to other vehicles and communicated to their drivers allowing them to take preventive actions. Initial experiments with a small scale demonstrator consisting of three passenger cars show considerable prospects to improve traffic safety.

Abstract

Piezometers are instruments that can produce high-quality information if suitable and effective installation and monitoring procedures are followed. In order to minimise errors and optimise quality of the obtained information, we must pay attention when prescribing the type of piezometer and its installation, as highlighted in the ISO/EN18674 standards. The use of piezometers as a geotechnical instrument is a commodity. This paper aims to exemplify how the use of piezometers can be optimised and how the most common errors can be avoided.

Abstract

Drilling boreholes for geotechnical purposes such as sampling and in situ tests is usually performed with the aid of drilling machines. In France, typically, the machine’s drilling parameters such as applied torque and thrust are monitored in realtime and registered so that information about the subsoil’s structure can be acquired. As these machines tend to use hydraulic systems, the oil pressures fed into each motor and actuator are the parameters commonly monitored. Recently, a new type of sensor and its application in geotechnical investigations through the measuring of drilling parameters was presented. This sensor is directly mounted on top of the drill string of a drilling machine and records the actual thrust, torque, and rotation speed transmitted to the drill string and bit. This bypasses the energy losses present in the hydraulic circuit between the machine’s pressure sensors and the hydraulic actuators. This mounting position allows a more accurate measurement of the forces and, furthermore, the effective rotation speed applied to the drill bit. The data is transmitted through a wireless Bluetooth connection enabling real time monitoring. Nevertheless, finding the right balance between a soil’s resistance, the drill rig’s power and the sensor’s optimal measuring range remains a topic for further development. This analysis of several worksites with different soils throughout France contributes to a better understanding of the last generation’s sensor’s precision and application range.
