Value orientation, left-right placement and voting

In this article we try to disentangle the constraints between traditional lines of political polarization (left-right placement) and newer distinctions (materialist/postmaterialist values) among mass publics. It is shown that voting or party preference is most clearly related to the left-right placement of the respondents. However, this placement is directly and strongly dependent on the materialist/postmaterialist orientation, while background variables like education, income and age are linked to voting via this value orientation. The materialist/postmaterialist orientation appears to be the present-day interpretation of the dominant political conflict in advanced industrial society. Although alignments and orientations count for a substantive part of the variance in voting, the power of these models to predict the actual vote of people turns out to be rather poor

Parallel algorithms for DNS of compressible flow

We indicate that the use of higher order accurate spatial discretization is necessary to obtain sufficiently accurate DNS for the validation of subgrid models in LES. Furthermore, we pay attention to the efficiency of the implementation of these discretizations on several parallel platforms. In order to illustrate this, we consider compressible flow over a flat plate. We give a priori test results for LES of this flow

Imagining sustainability: The added value of transition scenarios in transition management

Abstract Purpose – To address lessons that specify the impact and contribution of current scenario methods when focused on facilitating transition management processes. Design/methodology/approach – Comparative literature review based on transition management and scenario development. Research limitations/implications – Need of further systemic thought about the required criteria of transition scenarios and the embedding of scenario use in transition management processes. Practical implications – Processes of transition management are in need of transition specific scenarios. Originality/value – Because transition management implies a complex and long-term steering paradigm with which current scenario applications are not familiar, conclusions are drawn on the (changing) requirements of scenario development processes in transition management and on the need to innovate current scenario methods in the context of transition management

Polarization observables in electronuclear two-nucleon knockout

Differential (e,e'pp) measurements are presently recognized as a way of studying short-range correlations in finite nuclei. The ($\vec{e},e'\vec{p}p$) and ($\vec{e},e'\vec{p}n$) differential cross section and polarization observables are studied in a microscopic model that accounts for the short-range correlations, outgoing-nucleon distortions, meson-exchange and $\Delta$-isobar currents. It is pointed out that polarization observables represent an attractive alternative for absolute electronuclear two-nucleon knockout measurements. In the polarization transfer $P'_t$ for ($\vec{e},e'\vec{p}p$), the effect of central short-range correlations is predicted to be large while at the same time the final-state interaction effects are small.Comment: 8 pages, 4 figures, to be published in Physics Letters

Balancing demands and resources in sport:adaptation and validation of the demand-induced strain compensation questionnaire for use in sport

Too high demands, combined with a lack of resources, are often detrimental to athletic health and well-being. However, a valid and reliable instrument to investigate different dimensions of demands and resources in sport is currently unavailable. Therefore, the present study examines the psychometric properties of an existing and well-validated survey instrument on demands and resources at task-level that was adapted to sport. This instrument, the Demand-Induced Strain Compensation Questionnaire for Sport (DISQ-SPORT), was empirically tested among 1,101 athletes (416 females and 685 males) from a variety of sports and in different languages. Results supported the proposed six-factor structure of the instrument, consisting of physical, cognitive, and emotional demands and resources. Internal consistencies of all subscales were satisfactory and the instrument was invariant across type of sport, competitive level and language. Continued evaluation of the psychometric properties of the DISQ-SPORT, especially in terms of content validity and test-retest stability, is nevertheless warranted. Theoretical and practical implications as well as areas for future research are discussed.</p

Thyroidal and Extrathyroidal Requirements for Iodine and Selenium:A Combined Evolutionary and (Patho)Physiological Approach

Iodide is an antioxidant, oxidant and thyroid hormone constituent. Selenoproteins are needed for triiodothyronine synthesis, its deactivation and iodine release. They also protect thyroidal and extrathyroidal tissues from hydrogen peroxide used in the ‘peroxidase partner system’. This system produces thyroid hormone and reactive iodine in exocrine glands to kill microbes. Exocrine glands recycle iodine and with high urinary clearance require constant dietary supply, unlike the thyroid. Disbalanced iodine-selenium explains relations between thyroid autoimmune disease (TAD) and cancer of thyroid and exocrine organs, notably stomach, breast, and prostate. Seafood is iodine unconstrained, but selenium constrained. Terrestrial food contains little iodine while selenium ranges from highly deficient to highly toxic. Iodine vs. TAD is U-shaped, but only low selenium relates to TAD. Oxidative stress from low selenium, and infection from disbalanced iodine-selenium, may generate cancer of thyroid and exocrine glands. Traditional Japanese diet resembles our ancient seashore-based diet and relates to aforementioned diseases. Adequate iodine might be in the milligram range but is toxic at low selenium. Optimal selenoprotein-P at 105 µg selenium/day agrees with Japanese intakes. Selenium upper limit may remain at 300–400 µg/day. Seafood combines iodine, selenium and other critical nutrients. It brings us back to the seashore diet that made us what we currently still are
