Military targeting in the context of self-defence actions

In order to bring conceptual clarity to a particular dimension of the relationship between the jus ad bellum and the jus in bello regimes, this article explores the independent sources of a military targeting rule in both branches of international law. The aim is not to displace the jus in bello as the ‘lead’ regime on how targeting decisions must be made, or to undermine the traditional separation between these regimes. Rather, conceptual light is shed on a sometimes assumed but generally neglected dimension of the jus ad bellum’s necessity and proportionality criteria that may, in limited circumstances, have significance for our understanding of human protection during war, by covering possible gaps in the jus in bello targeting rules.

The 'ratione temporis' elements of self-defence

This article focuses on one particular factor that is of crucial importance to all self-defence actions. It is a factor that is almost always present in the application and appraisal of the right, but one that is not always explicitly engaged with: time. There are various ratione temporis elements underpinning the lawful exercise of the right of self-defence, and questions related to the timing of both an attack being responded to in self-defence and the response itself are notably controversial. The self-defence timeline is therefore charted, and the key legal debates encountered along its trajectory are identified. In particular, there is a focus on three temporal ‘stages’ of the right of self-defence: (i) the much-debated question of preventative forms of self-defence (the ‘before’); (ii) the timeliness of a state's defensive action, or what is sometimes called the need for the response to be ‘immediate’ (the ‘during’); and (iii) the duration of self-defence actions, including the crucial issue of when they must end (the ‘after’). The aim of this article is not to break new substantive ground with regard to these ‘stages’ as such, but is, rather, to draw together the temporal strands of self-defence in a more focused manner than is often the case in the literature.

Equation for the microwave backscatter cross section of aggregate snowflakes using the self-similar Rayleigh–Gans approximation

In this paper an equation is derived for the mean backscatter cross section of an ensemble of snowflakes at centimeter and millimeter wavelengths. It uses the Rayleigh–Gans approximation, which has previously been found to be applicable at these wavelengths due to the low density of snow aggregates. Although the internal structure of an individual snowflake is random and unpredictable, the authors find from simulations of the aggregation process that their structure is “self-similar” and can be described by a power law. This enables an analytic expression to be derived for the backscatter cross section of an ensemble of particles as a function of their maximum dimension in the direction of propagation of the radiation, the volume of ice they contain, a variable describing their mean shape, and two variables describing the shape of the power spectrum. The exponent of the power law is found to be −. In the case of 1-cm snowflakes observed by a 3.2-mm-wavelength radar, the backscatter is 40–100 times larger than that of a homogeneous ice–air spheroid with the same mass, size, and aspect ratio.

Pippi Longstocking, juvenile delinquent? Hachette, self-censorship and the moral reconstruction of postwar France

This paper looks at the blockages to the publication of children’s literature caused by the intellectual climate of the postwar era, through a case study of the editorial policy of Hachette, the largest publisher for children at this time. This period witnessed heightened tensions surrounding the social and humanitarian responsibilities of literature. Writers were blamed for having created a culture of defeatism, and collaborationist authors were punished harshly in the purges. In the case of children’s literature, the discourse on responsibility was made more urgent by the assumption that children were easily influenced by their reading material, and by the centrality of the young to the discourse on the moral reconstruction of France. As the politician and education reformer Gustave Monod put it: “penser l’avenir, c’est penser le sort des enfants et de la jeunesse.” These concerns led to the expansion of associations and publications dedicated to protecting children and promoting “good” reading matter for them, and, famously, to the 1949 law regulating publications for children, which banned the depiction of crime, debauchery and violence that might demoralise young readers. Using the testimonials of former employees, along with readers’ reports and editorial correspondence preserved in the Hachette archives, this paper will examine how individual editorial decisions and self-censorship strategies were shaped by the 1949 law with its attendant discourse of moral panic on children’s reading, and how national concerns for future citizens were balanced with commercial imperatives.
