The drug situation in Europe: an overview of data available on illicit drugs and new psychoactive substances from European monitoring in 2015.

Aim: A central task for the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) is to produce an annual report of the latest data available on drug demand and drug supply in Europe. This paper is intended to facilitate a better understanding of, and easier access to, the main quantitative European level data sets available in 2015.

Methods: The European reporting system formally covers all 28 European Union (EU) Member States, Norway and Turkey and incorporates multiple indicators alongside an early warning system (EWS) on uncontrolled new psychoactive substances (NPS).

Trends of heroin use and heroin injection epidemics in Europe: findings from the EMCDDA treatment demand indicator (TDI).

We estimate trends and geographical differences in the heroin epidemic in the European Union plus Croatia and Turkey by analyzing aggregated data on first heroin treatment admissions (cases) during 2000-2009. In 2005-2009 the proportion of drug injectors was higher in Central and Eastern European countries (CEECs) than in Western European countries (WECs), whereas the opposite occurred with mean age at first heroin use and first treatment. During this period, the number of cases, cases per center, and proportion of injectors in WECs declined, whereas mean age at first treatment and first heroin use increased.

Multidimensional Adaptation in MAS Organizations.

Organization adaptation requires determining the consequences of applying changes not only in terms of the benefits provided but also measuring the adaptation costs as well as the impact that these changes have on all of the components of the organization. In this paper, we provide an approach for adaptation in multiagent systems based on a multidimensional transition deliberation mechanism (MTDM). This approach considers transitions in multiple dimensions and is aimed at obtaining the adaptation with the highest potential for improvement in utility based on the costs of adaptation.

Reaching unanimous agreements within agent-based negotiation teams with linear and monotonic utility functions.

In this article, an agent-based negotiation model for negotiation teams that negotiate a deal with an opponent is presented. Agent-based negotiation teams are groups of agents that join together as a single negotiation party because they share an interest that is related to the negotiation process. The model relies on a trusted mediator that coordinates and helps team members in the decisions that they have to take during the negotiation process: which offer is sent to the opponent, and whether the offers received from the opponent are accepted.

Estimating the total mortality among problem drug users.

This paper's objective is to develop a method to estimate the total mortality among problem drug users. The total mortality is given by a base rate of mortality not related to drugs and the deaths that are directly and indirectly related to drugs. A fatal poisoning by drugs (overdose) is directly related to drugs, whereas a casualty due to a drug-related disease or a drug-related accident is indirectly related to drugs.

Drug-related mortality and its impact on adult mortality in eight European countries.

Objective: To estimate the mortality rates from drug-related deaths and other causes among problem drug users and population attributable risk of death due to opiate use in eight study sites in Europe.

Methods: Opiate users were recruited from drug treatment centres during the period 1990-1998 and deaths followed up through national or local mortality registries. Gender-specific overall mortality rate, proportion of deaths by cause (drug-related, HIV, other), standardized mortality ratios (SMRs), and the attributable risk fraction (ARF) were estimated.
