Using migration and navigation as a focus, this chapter looks at the movements of birds. The genetic, hormonal, and physiological control of migration is analysed as are the evolution of migratory strategies and routes. Particular emphasis is given to fuelling migration and the significance of stop-over behaviours during migratory movements. The conservation implications of migration and of movement in general are considered, and the impact upon migratory fuelling of neonicotinoids pesticides are discussed. Sections examining innate and learned route finding and the migratory cues (sun, stars, magnetic field, etc) used by birds to determine their location, and the direction in which they need to travel to arrive at a goal, are given. The role of memory in place finding and food storage is considered, as is the neurology of spatial memory. Techniques used by ornithologists to study bird movement are explained throughout the chapter.

Fundamental Consideration

The research presented in this paper has been developed within the European project MeLa* (“European Museums in an age of migrations”), which focuses on how contemporary migratory movements come to reshape the role of museums and archives as the privileged places of national identity and cultural memory.[1] The fundamental consideration on which the research is built is that today, under the impact of globalization and an increasing awareness of the positive role played by cultural diversity, museums can no longer pretend to represent culture in exclusively national or local terms, because they are facing the challenge of an increasingly diverse, transcultural and multilingual European society.

Based on published research on modifying the structure of water and water-containing systems, we assess external influence methods: temperature, magnetic field, light radiation, and their combination. We evaluate changes in the electrophysical, photo- and pH-metric biological, therapeutic, and other properties of water systems using non-destructive electrophysical research methods, i.e., thermometry, pH, laser interference, dynamic light scattering, microelectrophoresis, conductivity, surface tension, dielectric constant, polarimetric measurements, atomic force microscopy, and UV and EPR spectroscopy. The effects of temperature or magnetic field lead to a change in the content and size of water clusters, and physicochemical, biological, therapeutic, and other changes in the properties of water and water-containing systems. The combined effect of a magnetic field and curative mud and the impact of magnetised mineral water have a more pronounced therapeutic effect than only mineral water or curative mud. The data presented indirectly indicate structural changes in water and water-containing systems. We conclude that the primary mechanism of action of a magnetic field, light, or a combination of these factors on water and water-containing systems, including mineral water and therapeutic mud, is a change in the structure of water.

The Impact

Abstract In this article, we consider a pair of spin-1/2 particles with squeezing coupling serving as the physical carrier of quantum information. We then examine the dynamics of quantum correlation quantified by the entanglement and measurement-induced nonlocality (MIN) under the intrinsic decoherence. The impact of intrinsic decoherence on the dynamical behaviors of quantum correlations is investigated. We show that the MIN quantities are more robust, while intrinsic decoherence cause sudden death in entanglement. Besides, we highlight the role of spin squeezing coupling and external magnetic field on quantum correlation measures. Finally, we investigate the impact of weak measurement on MIN.

General Climate

Two studies examined the impact of macrolevel symbolic threat on intergroup attitudes. In Study 1 (N = 71), participants exposed to a macrosymbolic threat (vs. nonsymbolic threat and neutral topic) reported less support toward social policies concerning gay men, an outgroup whose stereotypes implies a threat to values, but not toward welfare recipients, a social group whose stereotypes do not imply a threat to values. Study 2 (N = 78) showed that, whereas macrolevel symbolic threat led to less favorable attitudes toward gay men, macroeconomic threat led to less favorable attitudes toward Asians, an outgroup whose stereotypes imply an economic threat. These findings are discussed in terms of their implications for understanding the role of a general climate of threat in shaping intergroup attitudes.
