The reticular theory of twinning gives the necessary conditions on the lattice level for the formation of twins. The latter are based on the continuation, more or less approximate, of a substructure through the composition surface. The analysis of this structural continuity can be performed in terms of the eigensymmetry of the crystallographic orbits corresponding to occupied Wyckoff positions in the structure. If {\cal G} is the space group of the individual and {\cal H} a space group which fixes the twin lattice obtained as an intersection of the space groups of the individuals in their respective orientations, then a structural continuity is obtained if (1) the eigensymmetry of an orbit under {\cal G} contains the twin operation; (2) the eigensymmetry of a union of orbits under {\cal G} contains the twin operation; (3) the eigensymmetry of a split orbit under {\cal H} contains the twin operation; or (4) the eigensymmetry of a union of split orbits under {\cal H} contains the twin operation. The case of the twins in melilite is analysed: the (approximate) restoration of some of the orbits explains the formation of these twins.

This chapter addresses hasidism after 1772. The year 1772 is generally regarded as a critical one, or at least an important turning point, in the history of hasidism. Three decisive events took place in that year which altered both the ideological and the organizational course on which the movement had originally embarked. The spring brought with it the first outbreak of bitter hostilities between the mitnaggedim and the hasidim in Vilna, whence the dispute quickly spread to other Jewish communities in Lithuania and Galicia. During the summer months, Belorussia was annexed to Russia, and Galicia to Austria, in the first partition of the disintegrating kingdom of Poland; as a result, parts of the Jewish (and hasidic) community in Poland which until then had formed a single cultural and political entity found themselves arbitrarily separated. At the end of the year, in December, the supreme leader of hasidism, R. Dov Ber, the Maggid of Mezhirech, died without leaving an ‘heir’ to take charge of the movement in his place.

This article examines the utilization of female Muslim factory workers, in a North Indian woodworking industry, as domestic labour in the homes of their employers. The ethnography illustrates the importance of considering hidden forms of domestic-sector employment where workers are coopted into domestic tasks. The illumination of ‘coopted domestic labour’ has implications for understanding the breadth and scope of the sector and contributes to debates around its regulation, definition, growth and feminization. Female Muslim factory workers did not see ‘coopted domestic labour’ as a livelihood ‘choice’ but as exploitation enabled through employers’ tactics, such as the use of advance payments, forms of ‘neo-bondage’, and through structural continuity across domestic and industrial contexts which situated women at the bottom of the labour hierarchy. It also involved complex negotiations around reputation, character and practices of purdah (veiling) which, whilst already an issue for those working in factories, became intensified when entering the homes of others. The article develops its contribution by introducing the category of ‘coopted domestic labour’ and empirically illustrating its intersection with gender norms, Islam, forms of neo-bondage and structural considerations.

Direct consequences of pacification of the Yarahmadzai Baluch by the Iranian army in the campaigns of 1928–35 were the prohibition and cessation of raiding, imposition of Iranian military and civilian officials over the tribe, and limited access to previously unavailable labor and goods markets and to national government resources. Whatever the economic and psycho-cultural dislocations resulting from pacification, there was great structural continuity within the Yarahmadzai. There was no interference by the Iranian government, whose policy was external control through indirect rule, and who paid the Sardar (tribal chief) a substantial yearly stipend.
