The 2030 Agenda in local entities: Does gender matter in reporting on the Sustainable Development Goals?

This study analyses the influence of the gender of elected officials on the level of disclosure of information about the Sustainable Development Goals (SDGs) by Spanish local governments, using a binary gender classification (man/woman). The results obtained from the websites of 102 municipalities from 2016 to 2021 reveal that the fact that the mayor is a woman has a positive and significant effect on the disclosure of SDG information, while the effect of the gender diversity of the councillors is positive, but not significant. Furthermore, the tendency to disclose SDG information is higher in those municipalities led by a woman with a higher percentage of women councillorsXunta de Galicia [Grant/Award Number: 2020 GPC GI-2016]S

Modelling the optimum hot workability of TiB reinforced Ti-6Al-4 V alloy by stability maps

Hot workability of Ti-6%Al-4%V and two whisker discontinuously reinforced materials, Ti-6%Al-4%V/1.2%TiB and Ti-6%Al-4%V/8.9%TiB, have been investigated. Hot uniaxial compression tests were carried out using a computer controlled thermomechanical simulator Gleeble machine at temperatures in the range 850 °C to 950 °C and strain rates ranging from 1 to 50 s−1. The microstructures and the compression test results were compared among the three materials. The Ti-6%Al-4%V/8.9%TiB material presented extensive cracking after deformation. In contrast, the Ti-6%Al-4%V/1.2%TiB material showed an interesting compromise between flow stress and workability. The parameters of the Garofalo equation were calculated for the three materials revealing apparent activation energies that increased with increasing TiB content. The modelling is carried out by stability maps that gives the temperature at a given strain rate to obtain optimal workability and the stresses that has to bear the equipment. Taken 5 s−1 as a reference strain rate, the temperature required to obtain a quality product increased from about 1143 K (870 °C) for the Ti-6-4 alloy without TiB to 1228 K (955 °C) for the 1.2%TiB and to 1283 K (1010 °C) for the 8.9%TiB material. Therefore, the production of parts of the TiB composites should be conducted at a higher forming temperature to avoid the presence of cracksGobierno de España, Ministerio de Economía y Competitividad.
