Colonial law in Africa involved European moral and legal codes representing some rules of western law, as well as elements of African customary law. However, the colonial situation embodying political and economic domination necessarily negated the ideal practice of the rule of law. Nevertheless, the need arose to introduce some aspects of western law and codes of administration, including salary and benefits schemes for African employees of the colonial government, and legal entitlements such as court trials for accused government employees. These considerations were deemed necessary, if at least to propitiate metropolitan critics of the colonial establishment. Also some rule of law was required for the organization of the colonial economy, including regulation of productive systems and commercial relations. As well, the need for indigenous support necessitated dabbling in indigenous customary conventions. In Muslim polities such as Kano in northern Nigeria, customary conventions included Islamic law.On the establishment of colonial rule in Kano, judicial administration was organized on three principal institutions, involving the resident's provincial court, the judicial council (emir's court), and the chief alkali's court in Kano City with corresponding district alkali courts. The resident's provincial court had jurisdiction over colonial civil servants, including African employees such as soldiers, police constables, clerks and political agents. Also, the provincial court was responsible for enforcing the abolition of the slave trade in the region. The judicial council, classified as “Grade A” court, was composed of the emir, thewaziri(chief legal counselor), the chiefalkaliof Kano (chief judge), theimam(the religious leader of Kano mosque), thema'aji(treasurer), and general assistants including some notable scholars of Kano city. The council adopted thesha'ria(Muslim law) and local Hausa custom, and its jurisdiction extended over “matters of violence, questions of taxation and administration, and cases involving property rights, whether over land, livestock, trade goods, or slaves.” On the issue of capital sentencing, the judicial council required the approval of the resident. The council was also prohibited from authorizing punishments involving torture, mutilation, or decapitation.

Introduction. The article deals with mathematical models of two main classes of processes in stochastic productive systems. For a multistage system, conditions of belonging to a “just-in-time” class or a class with infinite support of the time distribution function for productive operations are determined. Materials and Methods. Descriptions and investigations of models are carried out by trajectory (martingale) methods. For “just-in-time” systems and multistage stochastic productive systems, terms and methods of random walks in a random environment and birth and death processes are used. The results are formulated as descriptions of intensity characteristics of equalizers of point counting processes. Results. Two theorems are given and proved; they justify the proposed classification of the mathematical models of productive systems. The criteria of the belonging of the stochastic productive system to the class “just-in-time” are given. A theorem on the incompatibility of groups of “just-in-time” systems and systems infinite support of the time distribution for operations is proved. Discussion and Conclusion. The results show the feasibility of analyzing stochastic productive systems by martingale methods. The descriptions of terms of intensities of the equalizers time of productive processes admit generalization.

The paper is positioned in the emerging debate on the technological change brought about by the Fourth Industrial Revolution, often referred to as Industry 4.0. Our analysis is at the local, sub-national level. The aim is to explore what drivers and barriers local productive systems might face when seeking to embark on transitions that reconcile smart, equitable, and sustainable priorities, under enhanced models called Industry 4.0+. The novelty of the paper is to develop such models by designing a conceptual framework that juxtaposes the drivers and the barriers of sustainability transitions with local productive systems. This novel framework suggests possible pathways that local productive systems can initiate to achieve more equitable and green outcomes for their economy and society by directing the development of digital-related solutions.

A floristic analysis war conducted of the secondary vegetation derived from slash and burn agriculture in a montane rain forest region at Santa Cruz Tepetotutla, located in the Northern Oaxaca Range, Mexico. The analysis of the studied chronosequence is based on a collection of 2 668 specimens encountered in 60 parallel 0.01 ha belt transects (25 X 4 m), distributed in 18 second-growth stands with ages ranging between 5 and ca. 100 years. A total of 499 species were distinguished, which are distributed in 223 genera and 104 families (including 38 secondary vegetation species collected outside of the transects), among which the following growth forms are represented: trees, shrubs, herbs, herbaceous and woody climbers, palms, ferns, and epiphytes. Only 28 morphospecies were not determined to any taxonomic level. Floristic richness did not decrease nor increased significantly with stand age. In contrast, changing trends, albeit non significant, were observed for different life forms, as arboreal species gradually replaced herbaceous ones, whereas palms and tree ferns only appeared in stands of intermediate age and their abundances increased thereof. The results of this study suggest that a considerable proportion of the regional floristic diversity occurs in the secondary vegetation. The abandonment of traditional agricultural methods for modern but usually inadequate, productive systems threatens this floristic potential, because it affects characteristics of the system fundamental for the maintenance of species, such as stand age and the area of the primary vegetation matrix in which these stands are embedded.

The ovine population of the central Argentine territory is the result of constant introductions of different animal biotypes, which determined the existence of ovine populations with great variability. The main objective of the breeders is to produce a lamb for self-consumption and sale of surpluses, without considering the wool product. The production of a lamb for the market is compatible with the production of wool for the textile industry, having to evaluate the feasibility for the commercialization of lamb wool that they produce. This work aimed to provide information and tools to evaluate the quality of lamb’s wool and the evolution of the weight of lambs belonging to the native flocks of the area. Characterization of the productive systems was carried out, seeking to highlight the attributes of meat and wool of native lambs. The characteristics of wool and meat lamb product were evaluated under two treatments, either in free rage conditions or lambs supplemented under confinement. The analysis of the behaviour of the productive systems did not show significant differences between lamb biotypes, which allows affirming that the variation within an animal biotype is even more important than the expected one between biotypes. This indicates that both treatments can be used according to the particular situation of each productive unit. Therefore, it is possible to produce wool and meat of outstanding quality looking for the goodness of the wool produced and optimizing through proper handling practices the meat product.
