Abstract
A method is given for calculating rapidly and accurately, by the use of charts (Figs. 1–3), the still‐air range performance of jet‐propelled aircraft operating completely above the tropopause. Simple rules arc also derived in Section 3 for estimating the effect of small changes in certain parameters for use when a design is largely stabilized. Table I summarizes these rules by showing percentage changes in all‐up weight, fuel weight, mean cruising height, etc., for a given percentage change in other parameters, keeping certain other quantities constant. Appendix I shows the error involved by using an approximate rather than the accurate formula for estimating range. (See Section 3.) For simplification, the mean cruising height (defined as the height at which the aircraft weight is a mean between that at the beginning and that at the end of the cruising flight) is calculated, rather than the height over the target (i.e. half range height). Appendix II discusses the difference between the two heights. A typical range performance problem is worked out in Appendix III showing how the tables and charts arc used. Appendix IV gives some useful properties of that part of the I.C.A.N. standard atmosphere extending from the tropopause to 70,000 ft.

Abstract
FOR a number of years now it has been evident that a successor to the well‐tried Vickers Viscount and Convoir 240/340/440 series was required. However, the big problem was to design an aircraft such that its economics and passengerappealweresub‐stantially better than the machines it would ultimately replace. Other important factors which had to be con‐sidered were improved reliability, easier and cheaper maintenance, higher standards of safety and means of reducing ramp times. Furthermore, the difficult choice of passenger capacity and cruising speed had to be made. Probably the easiest decision was to employ the twin‐engine configuration with the power plants placed in the now familiar rear position, one on cither side of the fuselage.

Abstract
Although this chapter situates all violence against women as a human rights issue, it emphasises ‘culturalised’ forms of this violence, such as honour-based violence/abuse, forced marriage and female genital mutilation. The authors draw upon their respective research to highlight how these forms of gendered violence have been subjected to a process of culturalisation. The chapter shows that while this process has raised awareness of previously under-researched forms of abuse and highlighted some of the contextual differences between women’s experiences of violence more broadly, its overemphasis on culture and cultural pathology has resulted in policy and legislative responses that do not always benefit victims. Ultimately, this chapter aims to problematise ‘culturalised’ understandings of violence in diverse communities and to show how current policy, legislative and support responses fail to adequately address the intersectional needs of black and minority ethnic victims/survivors.1

Abstract
An obvious way to improve acquisition performance is to avoid completing value-destroying acquisitions. However, once announced, manager motivations often focus on completing acquisitions. The authors develop how external governance actors can interpret acquisition characteristics and make counter-signals that acquiring firm managers could use to improve acquisition outcomes. The authors specifically develop how managers may react to counter-signals by shareholders, media, analysts, and short sellers. While there is limited research considering these external governance actors, evidence suggests that managers’ reactions to these actors may vary. A more integrated assessment of external governance actors’ influence on acquisition completion offers an opportunity to better understand acquisition processes and performance.

Abstract
Radical feminists position any forms of sex work as gender violence against individuals and more broadly for all women in society. I argue against the ideological stance that sex work is inherently violent and as a result should be outlawed, setting out how this ideology and dogma has allowed structural factors to persist. In this paper, I argue that despite the unacceptable high levels of violence against sex workers across the globe, violence in sex work is not inevitable. Through a review of the literature as well as drawing on research from the United Kingdom, I deconstruct the myth of inevitable violence. In turn I argue that violence is dependent on three dynamics. First, environment: spaces in which sex work happens has an intrinsic bearing on the safety of those who work there. Second, the relationship to the state: how prostitution is governed in any one jurisdiction and the treatment of violence against sex workers by the police and judicial system dictates the very organization of the sex industry and the regulation, health and safety of the sex work communities. Third, I argue that social status and stigma have significant effects on societal attitudes toward sex workers and how they are treated. It is because of these interlocking structural, cultural, legal, and social dynamics that violence exists and therefore it is these exact dynamics that hold the solutions to preventing violence against sex workers. Toward the end of the paper, I examine the UK’s “Merseyside model” whereby police treat violence against sex workers as a hate crime. It is in these examples of innovative practice despite a national and international criminalization agenda against sex workers, that human rights against a sexual minority group can be upheld.

Abstract
Elsewhere in this issue we review the First (Interim) Report of the Joint Survey of Pesticide Residues in Foodstuffs, published by the Association of Public Analysts (Editor: Mr. D. G. Forbes, B.Sc., F.R.I.C.). The Scheme, planned with meticulous care and executed with the best spirit of co‐operation, sets a pattern for this type of investigation; there are other problems which could be studied in the same manner. Such a response from the bodies representing the major local authorities of the country and their food and drugs administrations—inspectors, food sampling officers, public analysts—is evidence of the concern felt over this particular form of contamination of food. It constitutes a public health problem of world‐wide dimensions. The annual reports of public analysts show that many are examining foods outside the Survey lists now that gas/liquid chromatography, spectroscopy and other highly refined methods of analysis are available to them.
