Mitigating Institutional Attitudes toward Sign Languages: A Model for Language Vitality Surveys.

This paper is about attitudes toward sign languages. The paper presents an idea to help make sign language surveys better in the future. In 2018, UNESCO (the United Nations Educational, Scientific and Cultural Organization) published a sign language survey and a spoken language survey together for the first time. This was very important to show that spoken languages and signed languages are equal. But the sign language survey has some weaknesses. The idea presented in this paper says that: when people make sign language surveys, they should be aware of discrimination and negative attitudes; they should give signers access to the survey in sign language; and they should help signers decide what actions they can do to protect their sign language.

The behaviour of residual contaminants at a former station site, Antarctica.

In 1994, New Zealand's only mainland Antarctic base, Vanda Station, was removed from the shores of Lake Vanda, in the McMurdo Dry Valleys region of southern Victoria Land, Antarctica. Residual chemical contamination of the station site has been identified, in the form of discrete fuel spills, locally elevated Pb, Zn, Ag and Cd concentrations in soil and elevated Cu, Ni, Co and phosphate concentrations in suprapermafrost fluids in a gully formerly used for domestic washing water disposal. Pathways for contaminant transfer to Lake Vanda, potential environmental impacts and specific remediation/monitoring options are considered. While some contaminants (particularly Zn) could be selectively leached from flooded soil, during a period of rising lake level, the small area of contaminated soils exposed and low level of contamination suggests that this would not adversely affect either shallow lake water quality or the growth of cyanobacteria. Phosphate-enhanced growth of the latte may, however, be a visible consequence of the minor contamination occurring at this site.
