Plastic Trait

Many behaviors of insects are stimulated, modified, or modulated by hormones. The principal hormones involved are the same as the ones that control moulting, metamorphosis, and other aspects of development, principally ecdysone and juvenile hormone. In addition, a small handful of neurosecretory hormones are involved in the control of specific behaviors. Because behavior is a plastic trait, this chapter begins by outlining the biology and hormonal control of phenotypic plasticity in insects, and how the hormonal control of behavior fits in with other aspects of the control of phenotypic plasticity. The rest of the chapter is organized around the diversity of behaviors that are known to be controlled by or affected by hormones. These include eclosion and moulting behavior, the synthesis and release of pheromones, migration, parental care, dominance, reproductive behavior, and social behavior.

Care Systems

This chapter reviews the public health care systems as well as their challenges. It first shows how expenditure on health care has evolved in previous decades and deals with the reasons for the growth observed in almost every European country. It emphasizes the role of technological progress as a main explanatory factor of the increase in medical expenditure but also points to the challenges facing cost-containment policies. Especially, the main common features of health care systems in Europe, such as third-party payment, single provider approach and cost-based reimbursement are discussed. Finally the chapter shows that although inequalities in health exist in the population, health care systems are redistributive. Reforms are thus needed but the trade-off between budgetary efficiency and equity is difficult.

Market Driven

New Zealand, like many other capitalist countries, has recently witnessed an increased corporate involvement in medicine. One manifestation of this change has been the entry of medical ‘supermarkets’—multipurpose clinics which juxtapose general practitioners (GPs) and specialists, are company owned, and employ advertising. The authors document the development and implications of these clinics which, although small in number, have induced change in the behaviour of the GP community at large. They conclude that recent developments involve a ‘coming out of the closet’ of a fundamental contradiction in the way general practice is conducted in New Zealand. This is between the role of the caring providers founded on the Hippocratic oath, and that of income-generating business people within an increasingly market-driven society. This contradiction leads to speculation on a broader question: The degree to which competition among primary care provides is possible within fee-for-service and other types of health-care systems.

AbstractNew observations on parental behavior of the earwig, Forficula auricularia L., are reported and the literature on the parental behavior in the Dermaptera is summarized. The construction of the nest, care of the eggs and nymphs, and the duration of parental care are described. The control of parental behavior and the role of the male in nest establishment are also considered.
