Class, resistance, and the psychologization of development in South Africa

This paper focuses on the psychologization of development in South Africa, one of the most unequal countries in the world, through a critical analysis of a discussion on a national radio programme about the meaning of Mandela Day. We demonstrate how speakers draw on common sense notions of race, class, and party politics that (re)produce subject positions from within a rights-based interpretive repertoire that emphasizes structural reform and class resistance, and an agency interpretive repertoire that emphasizes individualism, responsibility, and volunteerism. We further demonstrate how the agency subject position serves to stifle and resist the rights subject position by drawing on common sense 'psychological truths' about what it means to be a good citizen

Edge excitations and Topological orders in rotating Bose gases

The edge excitations and related topological orders of correlated states of a fast rotating Bose gas are studied. Using exact diagonalization of small systems, we compute the energies and number of edge excitations, as well as the boson occupancy near the edge for various states. The chiral Luttinger-liquid theory of Wen is found to be a good description of the edges of the bosonic Laughlin and other states identified as members of the principal Jain sequence for bosons. However, we find that in a harmonic trap the edge of the state identified as the Moore-Read (Pfaffian) state shows a number of anomalies. An experimental way of detecting these correlated states is also discussed.Comment: Results extended to larger systems. Improved presentatio

RELIABILITY OF THE BICAUDATE PARAMETER IN THE REVEALING OF THE ENLARGED LATERAL VENTRICLES IN SCHIZOPHRENIA PATIENTS

Introduction: In schizophrenia patients the lateral ventricle enlargement has mostly been reported in relationship with smaller cortical and/or subcortical brain volumes; and it has been observed that ventricular system growth may be a consequence of the smaller caudate nucleus volume. Bicaudate parameters have been used in the Alzheimer dementia and Huntington’s chorea diagnosing in order to evaluate brain changes and the enlargement of the lateral ventricles. Subjects and methods: This study has been carried out on 140 patients out of which 70 patients (30 men and 40 women) who met the ICD 10 criteria for schizophrenia and 70 healthy controls (30 men and 40 women) matched on sex and age with the studied group. All of them underwent direct caudatometry and volume computation based on MRI scans. Results: Except for the bicorporal line, for all the parameters were obtained the statistically highly significant differences between the examined and control groups. Significant correlation was established for the majority of bicaudate parameters and volumes of the caudate nuclei and lateral ventricles. Discussion: Enlargement of the lateral ventricles is one of the most frequent MRI finding in schizophrenia patients. Ventricles are enlarging gradually and frontal horns are more affected than other parts. The increased volumes of the caudate nuclei signalized that ventricular enlargement is not the consequence of the caudate atrophy. Conclusion: Bicaudate parameters are reliable parameters for the quick orientation in order to assess the enlarged ventricles in schizophrenia patients

Annealed disorder, rare regions, and local moments: A novel mechanism for metal-insulator transitions

Local magnetic moments in disordered sytems can be described in terms of annealed magnetic disorder, in addition to the underlying quenched disorder. It is shown that for noninteracting electron systems at zero temperature, the annealed disorder leads to a new mechanism, and a new universality class, for a metal-insulator transition. The transition is driven by a vanishing of the thermodynamic density susceptibility rather than by localization effects. The critical behavior near two-dimensions is determined, and the underlying physics is discussed.Comment: 4 pp., LaTeX, no figs., final version as publishe

Color measurement of animal source foods

Rapid and objective assessment of food color is necessary in quality control. The color evaluation of animal source foods using a computer vision system (CVS) and a traditional colorimeter is examined. With the same measurement conditions, color results deviated between these two approaches. The color returned by the CVS had a close resemblance to the perceived color of the animal source foods, whereas the colorimeter returned not typical colors. The effectiveness of the CVS is confirmed by the study results. Considering these data, it could be concluded that the colorimeter is not representative method for color analysis of animal source foods, therefore, the color read by the CVS seemed to be more similar to the real ones

High-Precision Measurement of the 19Ne Half-Life and Implications for Right-Handed Weak Currents

We report a precise determination of the 19Ne half-life to be $T_{1/2} = 17.262 \pm 0.007$ s. This result disagrees with the most recent precision measurements and is important for placing bounds on predicted right-handed interactions that are absent in the current Standard Model. We are able to identify and disentangle two competing systematic effects that influence the accuracy of such measurements. Our findings prompt a reassessment of results from previous high-precision lifetime measurements that used similar equipment and methods.Comment: 5 pages and 5 figures.
