Digital Photogrammetry for Documentation of Maritime Heritage

Documentation of maritime heritage is essential for its protection, and for reference in restoration and renovation processes. These functions become problematic in the case of historical ships and boats that lack lines drawings. The purpose of this paper is to describe a procedure for creation of lines drawings based on the shape analysis of surviving historical boats or their small-scale models with the help of reverse engineering (RE) techniques. The paper describes how digital photogrammetry and the iterative method were used to analyze the shape of three historical boats: Tomahawk, Refola and Nada. The application of the proposed procedure produced the lines drawings of the boats as its result. The accuracy of the 3D CAD model obtained with the photogrammetric technique was verified by comparing it against a more accurate 3D model produced with the help of a RE laser scanner. The examination of the resulting lines drawings proves that the digital photogrammetry process and the proposed iterative method are adequate tools for developing lines plans of boat models. The research offers the methodological basis for the creation of an archive of lines drawings of historical boats. Such an archive would provide reference for philologically correct restorations, and permit definition and classification of distinctive elements of various types of historical boats, particularly those produced in the Campania Region.     

Gendered division of labour and feminisation of responsibilities in Kenya; implications for development interventions

Analysing gender roles as a social organisation element of a community is critical for understanding actors’ rationales and agency with regard to allocation and use of resources. This article discusses gender relations and how they determine development outcomes, based on a highland-lowland case-study of participants of Farmer Field Schools in Kakamega Central Sub-County (highland) and Mbeere South Sub-County (lowland). The gender relations at stake include the gendered division of labour, gender roles and intra-household power relations as expressed in access and control of resources and benefits and their implications for agricultural development. The study used mixed methods, the Harvard Analytical Framework of gender roles and draws on the Neo-Marxist position on exploitation, categorisation and institutionalisation of power relations, empowerment and the critical moments framework to discuss the results. Results in both Sub-Counties show that patriarchy prevails, determining institutional design, access and control of resources and benefits. Social positions shape capabilities and strategies of actors in decision-making and use of resources to justify gender-specific institutional arrangements. In Kakamega, men get the lion share of incomes from contracted sugarcane farming despite overburdening workloads on women, while in Mbeere, both men and women derive incomes from Khat (Catha Edulis) enterprises. However, women are expected to spend their earnings on household expenditures, which were hitherto responsibilities of men, thereby contributing to the feminisation of responsibilities. Development policies and interventions thus need to be based on an understanding of men and women’s differential access and control over resources and the institutions underpinning men and women’s bargaining power in order to adopt more effective measures to reduce gender inequalities.
