Sociología y drogodependencia: la mirada ténica en la intervención social. Fundamentos para la constitución de una sociología de las drogodependencias

Almost thirty years have passed since the City Council of Madrid approved the first Municipal Plan against Drugs, thus laying the foundations of the current commitment to offer assistance to drug addicts. A Service that has been continuously growing (in funding), maturing (in organizations) and diversifying (in actions) during these decades, in the same manner as the scenario in which these actions are deployed has been evolving. But, what can be said today about the status of drugaddiction intervention? This study adopts a sociological approach that starts with and is focused on what has been defined as the hegemonic vision on drug addiction, with the aim of studying (precisely and progressively) the different and most widely accepted theoretical-practical developments and to understand how certain conceptions or positions determine the form of this social fact. Therefore, the main objective of this study is to understand and evaluate the performative effects of certain practices, techniques and professionals on defining and addressing a reality that is in question and/or in conflict, as a social problem. In addition, this study is focused on identifying a series of fundamental elements to address what is understood as the state of the issue of drug addiction in depth (discourse of drugs Vs. discourse on drugs) in order to offer a series of sociological questions and insights to focus attention onto this reality. For this purpose, once its intentions have been defined and due to the social nature of the object under study, the present research deploys qualitative methodology as a tool for approximation, delimiting the scope that professional technicians assume regarding the issue in question as well as their own professional practices within their organizations. Thus, we have contacted certain public as well as non-governmental organizations with long-term experience in drug addiction, so as to find out first hand, in addition to their writings, the different meanings they find in the performance of their specific practice (micro) as well as the framework within which their practice is defined and materialised (macro) on a population defined or characterised by (drug) addiction...

Thermal reference points as an index for monitoring body temperature in marine mammals

BACKGROUND Monitoring body temperature is essential in veterinary care as minor variations may indicate dysfunction. Rectal temperature is widely used as a proxy for body temperature, but measuring it requires special equipment, training or restraining, and it potentially stresses animals. Infrared thermography is an alternative that reduces handling stress, is safer for technicians and works well for untrained animals. This study analysed thermal reference points in five marine mammal species: bottlenose dolphin (Tursiops truncatus); beluga whale (Delphinapterus leucas); Patagonian sea lion (Otaria flavescens); harbour seal (Phoca vitulina); and Pacific walrus (Odobenus rosmarus divergens). RESULTS The thermogram analysis revealed that the internal blowhole mucosa temperature is the most reliable indicator of body temperature in cetaceans. The temperatures taken during voluntary breathing with a camera held perpendicularly were practically identical to the rectal temperature in bottlenose dolphins and were only 1 °C lower than the rectal temperature in beluga whales. In pinnipeds, eye temperature appears the best parameter for temperature control. In these animals, the average times required for temperatures to stabilise after hauling out, and the average steady-state temperature values, differed according to species: Patagonian sea lions, 10 min, 31.13 °C; harbour seals, 10 min, 32.27 °C; Pacific walruses, 5 min, 29.93 °C. CONCLUSIONS The best thermographic and most stable reference points for monitoring body temperature in marine mammals are open blowhole in cetaceans and eyes in pinnipeds.

Design of maintenance structures for rural electrification with solar home systems. The case of the Moroccan program.

n decentralised rural electrification through solar home systems, private companies and promoting institutions are faced with the problem of deploying maintenance structures to operate and guarantee the service of the solar systems for long periods (ten years or more). The problems linked to decentralisation, such as the dispersion of dwellings, difficult access and maintenance needs, makes it an arduous task. This paper proposes an innovative design tool created ad hoc for photovoltaic rural electrification based on a real photovoltaic rural electrification program in Morocco as a special case study. The tool is developed from a mathematical model comprising a set of decision variables (location, transport, etc.) that must meet certain constraints and whose optimisation criterion is the minimum cost of the operation and maintenance activity assuming an established quality of service. The main output of the model is the overall cost of the maintenance structure. The best location for the local maintenance headquarters and warehouses in a given region is established, as are the number of maintenance technicians and vehicles required.
