Session 3: Diversity Enhancing Intellectual Property, Jordi Goodman, Nina Srejovic
SITIE Symposiums
The field of intellectual property suffers from a lack of diversity. Women are underrepresented as credited inventors in the United States. Additionally, multi-gender inventor groups are underrepresented compared to all-male and, sometimes, even all-female groups. This representation has changed over time, with changes not always reflecting an increase in female representation. This is particularly true when studying gender-disparity as it exists in the field of computer programming and software patents. While women were well represented in computer programming at field’s inception, this changed after World War II because men lobbied to push women out of the field. Women have since …

Reintroducing Hemp (Rongony) In The Material Palette Of Madagascar: A Study On The Potential Of Hemp Clay Components And Its Impact On Social And Ecological Communities., Henintsoa Thierry Andrianambinina
Masters Theses
When mentioning the word hemp, especially in the local language of Madagascar, the literal translation does not set it apart from marijuana, as they are both called “rongony” - creating the stigma around hemp as the negative stereotype of marijuana. However, the material has been used by the ancestors of Madagascar, as well as across cultures, in its fibrous form to produce fabrication like textile goods and packaging. During colonization, the prohibition of hemp intensified, and since then, any activity related to either of these plants is prohibited and will end in severe punitive measures.

Policy Uncertainty Reduces Green Investment, Mengyu Wang, Jeffrey Wurgler, Hong Zhang
Policy Uncertainty Reduces Green Investment, Mengyu Wang, Jeffrey Wurgler, Hong Zhang
Research Collection Lee Kong Chian School Of Business
Government subsidies are often used to stimulate environment-friendly investment. We find that Chinese firms reduce green investment as the uncertainty of subsidies rises. This effect is identified from weather-driven fluctuations in air pollution that lead to fluctuations in subsidy allocations: Firms in cities where weather-driven subsidy uncertainty is high engage in less green R&D investment, patent applications, and research staff. Industries that are heavy emitters and those focused on environmental technologies are more affected. The results suggest that policy uncertainty may originate not only from political and macroeconomic shocks but from behavioral mechanisms that link policy to salient recent conditions.
