Technological status and development prospects of small-scale fishing crafts in Nigerian coastal water

A study of fishing crafts was conducted in some coastal states of Nigeria to elucidate findings on the existing crafts as the baseline for further developments. Based on the technical designs, three types of fishing crafts were identified; planked, dug-out and half dug-out canoes. The planked canoes have the largest cubic number and dug-out canoes the least. At loadwater line, the ratio of freeboard to draft was 2 : 1 for planked canoes, indicating reserved buoyancy. Trim of planked canoe is by stern; the beam-length ratio for dug-out canoes showed high drag. Most of the sea-going canoes have U-shaped bottom hull profile capable of withstanding the rigours of surf landing and displayed good stability against longitudinal water wave. Gunwale and thwarts provided respectively the longitudinal and transverse strength of planked and half dug-out canoes. With its characteristics 'weight low down' construction, planked canoe represent the climax of small scale fishing crafts developments in Nigerian coastal waters. It's only draw back is durability. Further improvement in this canoe should be aimed at increasing the hull size and stiffness, water tightness of deck by coating, caulking, fastening, increasing level of motorization and installation of deck working equipments. Experimental design and use of fibre glass, aluminium and ferrocement hulls, together with improved planked canoe is highly advocated

Technological unemployment

This work investigates the relationship between unemployment and technological progress. We analyze briefly the historical context in which the problem of unemployment begins: the emergence of a new economic system, the capitalism. In our research we consider the contributions of two different economists: John Stuart Mill and Karl Marx. They offer two different perspectives to this subject. We also consider the contribution David Ricardo, the first author that realized the conflictive relationship between technical progress and the interest of the workers. We also include an analysis of the problem by using different data collected from Global Wage Report, that is annually offered by the International Labor Organization (ILO). Finally, we also analyze the phenomenon called planned obsolescence. The idea of producing goods with low quality in order to guarantee a future demand (replacing the obsolete goods) has been considered a good option to avoid unemployment. This work ends with some final comments and open questions.

Gender segregation in technological undergraduate studies in the University of the Basque Country (UPV/EHU)

In this work we study the gender segregation in technological undergraduate studies in the University of The Basque Country (UPV/EHU). For this study we use the data of new admissions at the UPV/EHU. They are from the time period of the years 2003-2013. We focus on the first and last year to check if the segregation has changed over these ten years. We build segregation curves within the Lorenz approach. Our results show that the gender segregation in technological undergraduate studies in the University of the Basque Country has increased over the last ten years. We also show that the distribution between men and women has changed.
