The history of the General Agreement on Tariffs and Trade negotiations is full of anecdotes on missed deadlines, failed ministerial conferences, and brinkmanship situations. Tactics such as walking away from the table or sleep-depriving night sessions are legendary in the context of attempting to overcome impasse in negotiations. This article traces and explains the recurrent deadlock in the Doha Round negotiations. It identifies four structural/contextual factors – ideas, institutions, interests, and information – as necessary for understanding and anticipating potential deadlocks. The article also offers a definition of deadlock, and discusses a set of factors highlighted in the international relations literature that explain the existence and persistence of deadlock. With the help of game theory, it then illustrates the challenges faced by actors during trade negotiations. The article concludes by outlining two general scenarios for the Doha Development Agenda and discusses their implications for the World Trade Organization.

OBJECTIVES To explore the experiences of oncology staff with communicating safety concerns and to examine situational factors and motivations surrounding the decision whether and how to speak up using semistructured interviews. SETTING 7 oncology departments of six hospitals in Switzerland. PARTICIPANTS Diverse sample of 32 experienced oncology healthcare professionals. RESULTS Nurses and doctors commonly experience situations which raise their concerns and require questioning, clarifying and correcting. Participants often used non-verbal communication to signal safety concerns. Speaking-up behaviour was strongly related to a clinical safety issue. Most episodes of 'silence' were connected to hygiene, isolation and invasive procedures. In contrast, there seemed to exist a strong culture to communicate questions, doubts and concerns relating to medication. Nearly all interviewees were concerned with 'how' to say it and in particular those of lower hierarchical status reflected on deliberate 'voicing tactics'. CONCLUSIONS Our results indicate a widely accepted culture to discuss any concerns relating to medication safety while other issues are more difficult to voice. Clinicians devote considerable efforts to evaluate the situation and sensitively decide whether and how to speak up. Our results can serve as a starting point to develop a shared understanding of risks and appropriate communication of safety concerns among staff in oncology.

Myxozoans evoke important economic losses in aquaculture production, but there is almost a total lack of disease control methods as no vaccines or commercial treatments are currently available. Knowledge of the immune responses that lead to myxozoan elimination and subsequent disease resistance is vital for shaping the future development of disease control measures. Different fish immune factors triggered by myxozoan parasites are reviewed in this chapter. Detailed information on the phenotypic and underlying molecular aspects of innate and adaptive responses, at both cellular and humoral levels, is provided for some well-studied fishmyxozoan systems. The importance of the local immune response, mainly at mucosal sites, is also highlighted. Myxozoan tactics to disable or avoid immune responses, such as modulation of immune gene transcription and immune evasion, are also reviewed. The existence of innate and acquired resistance to some myxozoan species suggest promising possibilities for controlling myxozooses through immune-based strategies, such as genetic selection for host resistance, vaccination, immune therapies and administration of immunostimulants.
