This chapter contributes to the debates around television drama and black representation that are presented in this book collection. It focuses on Shoot the Messenger (STM) (BBC2, 2006), which was heavily promoted by the BBC as a ‘bold’ and ‘thought-provoking’ television drama. The one-off ninety-minute BBC Drama production focuses on the psychological journey of a Black schoolteacher, Joe Pascale (portrayed by David Oyelowo), accused of assaulting a Black male pupil. This chapter discusses how stylistically, STM’s non-realist techniques, non-linear form and overt constructedness depart from the traditional modes of social realism that have prevailed in Black British television drama. Moreover, it breaks with British television drama traditions in terms of production, having an almost totally Black cast and written and produced by two Black women: Sharon Foster and Ngozi Onwurah respectively.

Abstract In this article we examine patterns of root allomorphy in Greek that involve vowel alternations and propose a Generalized Non-linear Affixation (Bermúdez-Otero 2012) analysis according to which these alternations result from the competition between segments that belong, on the one hand, to the vocabulary items of roots and, on the other, to the exponents of functional heads (Voice/Aspect, n). More specifically, we claim that phonological entities have a gradient degree of presence in a structure, that is, are specified with a certain activation strength value underlyingly (Smolensky and Goldrick 2016). As a result, the surface realization of roots is determined by the relevant activation level of the exponents of functional heads they are eventually combined with. From all available exponents, the one that optimally complements the strength value of the vocabulary item of a given root will eventually surface. Our analysis is shown to be theoretically advantageous because it develops a strictly phonological account of allomorphy and, moreover, it captures the attested generalizations without resorting to extensive stem/span listing or to the application of phonologically unrestricted readjustment rules.

Abstract Given the recent fluctuation in the exchange rate and the presence of several factors such as the various economy-political sanctions (mainly embargos on oil and banking), extreme volatility in different economic fields, and consequently the devaluation of national and public procurement -A landmark that is emanating from exchange rate fluctuation - two points should be noted: First, it is essential to review the effect of exchange rate fluctuation on macro economic variables such as inflation and to provide appropriate policies. Second, the existence of this condition provides the chance to study the relation between exchange rate and inflation in a non-linear and asymmetric method. Hence, the present study seeks to use TAR model and, on the basis of monthly time series data over the period March 2002 to March 2014, to analyze the cross-asymmetric and non-linear exchange rate on consumer price index (CPI) in Iran. The results also show the presence of an asymmetric long-term relationship between these variables (exchange rate and CPI). Also, in the Iranian economy, the effect of negative shocks of exchange rate on inflation is more sustainable than the one from positive shocks.

AbstractWe introduce some non-linear transformations from the set of Hausdorff moment sequences into itself; among them is the one defined by the formula: . We give some examples of Hausdorff moment sequences arising from the transformations and provide the corresponding measures: one of these sequences is the reciprocal of the harmonic numbers .

Based on the first-order non-linear von Karman theory, cylindrical bending of functionally graded (FG) plates subjected to mechanical, thermal, and combined thermo-mechanical loadings are investigated. Analytical solutions are obtained for an FG plate with various clamped and simply-supported boundary conditions. The closed form solutions obtained are very simple to be used in design purposes. The material properties are assumed to vary continuously through the thickness of the plate according to a power-law distribution of the volume fraction of the constituents. The effects of non-linearity, material property, and boundary conditions on various response quantities are studied and discussed. It is found that linear analysis is inadequate for analysis of simply-supported FG plates even in the small deflection range especially when thermal load is present. Also it is shown that bending—extension coupling can not be seen in response quantities of clamped FG plates. Also an exact solution is developed for the one-dimensional heat conduction equation with variable heat conductivity coefficient.

Abstract The aim of this comparative study between the French and American markets, characterized by a different ownership structure is to examine the relationship between managerial ownership, the board of directors, the equity-based compensation and corporate performance. Regardless of the selected sample, we found on the one hand, a non-linear relationship between managerial ownership and firm performance and on the other hand, in the case of managerial entrenchment board of directors is a substitute for managerial ownership to solve the agency problem. In addition, stock-based compensation is non-linear function with managerial ownership, contrary to previous studies that assume a monotonous or non-significant relationship. The hypothesis of endogeneity is valid only in the American case. This result leads us to believe that the U.S. CEO has a preference to hold a large percentage of shares of firms that generate a good performance to neutralize capital market monitoring. Our study is exclusive in terms of the effect of managerial ownership on corporate performance in terms of comparison between two markets, characterized by a difference in ownership structure. We determine the impact of equity compensation on the one hand, the managerial ownership where all the studies assume either a monotone or neutral relationship between these two variables and on the other hand, the effect of board in the alignment or managerial entrenchment cases.
