New approaches to understanding the role of the news media in the formation of public attitudes and behaviours on climate change

This article examines the role of news media on climate change and sustainable energy in the shaping of audience opinions and beliefs and the possible relation of these to behaviours. It reports on a series of studies conducted between 2011 and 2014 which develop existing approaches to audience reception analyses by using innovative methodologies which focus specifically on the negotiation of new information in response to existing beliefs, perceptions and behavioural patterns – both in the short and long term. Audience groups are introduced to new information, to which the range of responses is examined. This approach allows for an exploration of the interplay of socio-political and personal factors as well as the identification of the potential informational triggers for change. The findings suggest that media accounts are likely to have a shaping role in relation to behaviours under a range of specific and coinciding conditions

Quantum Zeno effect in atomic spin-exchange collisions

The suppression of spin-exchange relaxation in dense alkali-metal vapors discovered in 1973 and governing modern atomic magnetometers is here reformulated in terms of quantum measurement theory and the quantum Zeno effect. This provides a new perspective of understanding decoherence in spin-polarized atomic vapors.Comment: 4 pages, 1 figur

Research Investigation Directed Toward Extending the Useful Range of the Electromagnetic Spectrum

The report discusses completed and proposed research in atomic and molecular physics conducted at the Columbia Radiation Laboratory from July 1972 to June 1973. Central topics described include the atomic spectra and electronic structure of alkali metals and helium, molecular microwave spectroscopy, the resonance physics of photon echoes in some solid state systems (including Raman echoes, superradiance, and two photon absorption), and liquid helium superfluidity

Celebrating Success: What Helps Looked After Children Succeed

The aim of this study was to understand from people who have experienced being looked after, what helped them become and feel successful. We wanted to listen to those who had gone on to experience success in their lives, and to find out what they felt made a difference. The key messages of this study are that being looked after can provide an opportunity for positive change in a child's life, but that the attitudes and actions of adults who provide direct care for looked after children, or who support their care in other ways, are critical. Meaningful relationships with skilled, caring and committed adults, and the opportunity to experience stability and consistency emerged from the study as particularly important

Extracting Hidden Symmetry from the Energy Spectrum

In this paper we revisit the problem of finding hidden symmetries in quantum mechanical systems. Our interest in this problem was renewed by nontrivial degeneracies of a simple spin Hamiltonian used to model spin relaxation in alkali-metal vapors. We consider this spin Hamiltonian in detail and use this example to outline a general approach to finding symmetries when eigenvalues and eigenstates of the Hamiltonian are known. We extract all nontrivial symmetries responsible for the degeneracy and show that the symmetry group of the Hamiltonian is SU(2). The symmetry operators have a simple meaning which becomes transparent in the limit of large spin. As an additional example we apply the method to the Hydrogen atom.Comment: 14 pages, 1 figure.
