    An advanced modification of dynamic gravitation

    The equations for the specification of the curvature of space-time are inherent in the general theory of relativity (GTR). However, despite its enormous success, there are a number of difficulties with GTR. Standard GTR is mathematically very complex, and it predicts the formation of black hole singularities. Here we reformulate the equations for gravitation by mathematically defining the equations for the curvature of space-time. We then translate this curvature back into equations for the force of gravity. By using the original equations for calculating the curvature of space-time used in GTR, we can translate the equations for gravitation, back into equations for a modified force of Newtonian gravity. Using worked examples, we show that such an adaptation of gravity, gives results which technically give the same results as GTR, in the mass range of the solar system. At the same time, an analysis of the data shows that with binary pulsars, the new equations can give improved results to GTR. In the case of high mass gravitational objects such as black holes, by using this advanced modified dynamic gravitation, AMDG, these equations also specifically resolve the difficulties of the formation of singularities

    Purpose &ndash; The aim of this exploratory study was to examine and compare a range of business values held by farmers and food processors. Design/methodology/approach &ndash; Questionnaires with a section on business values were posted to 200 farmers and 200 food processing businesses in Victoria, Australia, with response rates of 44 per cent (n=69) and 31 per cent (n=48), respectively, achieved. Findings &ndash; The most important of the 28 value items for farmers were high quality produce, honesty, and caring for employees. For processors, the most important values were quality products, customer value, and caring for employees. Between group differences reached statistical significance for one-third of the items. In particular, processor businesses valued innovation and convenience products more highly and had a stronger process orientation than did farming businesses. Environmental sustainability, caring for the community, and providing healthy products were more integral to farming than processing businesses. Research limitations/implications &ndash; The main limitation was the small sample sizes, although it is likely that response bias was not high. Future research could survey a larger sample of food industry representatives and examine the values held by other food industry sectors. Practical implications &ndash; This information could increase the effectiveness of communications with industry groups on a range of issues and in the formulation of appropriate health and environmental policies. Originality/value &ndash; To the authors\u27 knowledge, this is the first study to compare the values of farmers and food processors. This information is particularly important for those in the food industry and health and environmental policy makers.<br /

    Random fields of multivariate test statistics, with applications to shape analysis

    Full text link
    Our data are random fields of multivariate Gaussian observations, and we fit a multivariate linear model with common design matrix at each point. We are interested in detecting those points where some of the coefficients are nonzero using classical multivariate statistics evaluated at each point. The problem is to find the PP-value of the maximum of such a random field of test statistics. We approximate this by the expected Euler characteristic of the excursion set. Our main result is a very simple method for calculating this, which not only gives us the previous result of Cao and Worsley [Ann. Statist. 27 (1999) 925--942] for Hotelling's T2T^2, but also random fields of Roy's maximum root, maximum canonical correlations [Ann. Appl. Probab. 9 (1999) 1021--1057], multilinear forms [Ann. Statist. 29 (2001) 328--371], χˉ2\bar{\chi}^2 [Statist. Probab. Lett 32 (1997) 367--376, Ann. Statist. 25 (1997) 2368--2387] and χ2\chi^2 scale space [Adv. in Appl. Probab. 33 (2001) 773--793]. The trick involves approaching the problem from the point of view of Roy's union-intersection principle. The results are applied to a problem in shape analysis where we look for brain damage due to nonmissile trauma.Comment: Published in the Annals of Statistics (http://www.imstat.org/aos/) by the Institute of Mathematical Statistics (http://www.imstat.org

    “Style City” How London became a Fashion Capital

    Get PDF
    The book explains and explores in a critical as well as a celebratory way the birth of today’s London Designer identity and the evolution of London Fashion Week. It starts in the mid-Seventies when the cultural recognition of British fashion designers scarcely existed. It covers the rise of Vivienne Westwood, John Galliano, Katharine Hamnett and many others who were to become household names. But at the same time, it relates the persistent failure of the British government and the clothing industry to respond to successive opportunities, leaving designers to create an industry for themselves. It ends with British designers established worldwide and London Fashion Week as one of the world’s four premier fashion events
