title: Positive and Negative Affect Schedule (PANAS)

authors: Roemer, Anja

abstract: The Positive and Negative Affect Schedule (PANAS) is a widely used measure for assessing levels of positive and negative affect. Its excellent psychometric properties make it a popular tool among researchers. This chapter provides an overview of the PANAS, outlining its theoretical background and describing its initial development and validation. It presents the results of factor analysis and reliability statistics, as well as evidence for its construct validity. It is important to note that affective measures such as the PANAS are particularly valuable in mindfulness research. The ability to regulate one’s affective states is a crucial component of mindfulness, and the PANAS can help researchers assess how mindfulness interventions impact affective states. This chapter also highlights more recent studies that support the psychometric properties of the PANAS and its usefulness in mindfulness research. The PANAS has been used in many languages and has demonstrated adequate reliability and validity across different cultures. Overall, the PANAS is an important tool for assessing affective states in research, particularly in the context of mindfulness interventions.

title: Anisotropic three-dimensional MHD turbulence

authors: Matthaeus, William H.

subjects: MHD

abstract: Direct spectral method simulation of the three-dimensional magnetohydrodynamics (MHD) equations is used to explore anisotropy that develops from initially isotropic fluctuations as a consequence of a uniform applied magnetic field. Spectral and variance anisotropies are investigated in both compressible and incompressible MHD. The nature of the spectral anisotropy is consistent with the model of Shebalin et al. [1983] in which the spectrum broadens in the perpendicular wavenumber direction, the anisotropy being greater for smaller wavenumbers. Here this effect is seen for both incompressible and polytropic compressible MHD. In contrast, the longitudinal (compressive) velocity fluctuations remain isotropic. Variance anisotropy is observed for low plasma beta compressible MHD but not for incompressible MHD. Solar wind observations are qualitatively consistent with both variance and spectral anisotropies of the type discussed here.

title: The arguing genre and the explaining genre: A comparison in terms of discourse relational analyses of texts written in English and texts written in Māori

authors: Crombie, Winifred

subjects: Māori linguistics

abstract: There is a commonly held belief that those who are immersed in indigenous cultures have a tendency, when constructing academic texts, to avoid sequential, deductive argumentation. We report here on a comparison of two groups of texts exhibiting two different genres - 'explaining' and 'arguing'. One group of texts was written in Māori by indigenous authors, the other group was written in English by non-indigenous authors. Our findings are that although the percentage use of logico-deductive relationships is roughly equivalent for both groups of texts/ writers in the case of the explaining genre, the Māori texts/ writers use almost twice the percentage of logico-deductive relationships as do the English texts/ writers.
