title: Photosynthetic carbon assimilation drives leaf area expansion but not growth duration across northern ecosystems

description: Vegetation spring phenology signals the start of vegetation functional recovery in ecosystems and plays a vital role in shaping the global carbon cycle. Among key spring phenological events, leaf growth directly influences carbon dioxide exchange on a global scale. However, the extent to which photosynthetic carbon assimilation in one year influences leaf growth in the subsequent year remains difficult to quantify. Using satellite-derived leaf area index (LAI) data, we estimated the start of the growing season (SOS) and the peak of the growing season (POS), dividing the leaf growth process into two components: leaf area increment (∆LAI) and leaf growth duration (∆DOY). Our results show that ∆LAI in northern ecosystems is experiencing a significant upward trend, with over 10.7% of the region exhibiting ∆LAI growth rates exceeding 0.2 m2 m–2 year–1. This trend is primarily driven by solar radiation and photosynthetic carbon assimilation. In contrast, ∆DOY shows only a slight shortening trend, with most changes ranging from –0.2 to 0.2 days year–1. Moreover, the influence of photosynthetic carbon assimilation on ∆DOY appears minimal, likely because photosynthesis affects the timing of both SOS and POS simultaneously. Our findings demonstrate that photosynthetic carbon assimilation primarily drives leaf area expansion, with limited effects on leaf growth duration in northern ecosystems. This study contributes to advancing vegetation phenology theories, emphasizing that accurately quantifying the impacts of photosynthetic carbon assimilation is crucial for improving future predictions of vegetation seasonality and the carbon cycle.

title: <b>Identificación religiosa y percepciones sobre guerra, justicia y paz en jóvenes universitarios</b>

description: This exploratory qualitative study, conducted with 175 students from Mexican universities, examined the relationship between religious identification and attitudes toward five scales: militarism, pacification, undervaluation of peace, hatred of war, and the concept of a just world. The results indicate that students with belief in a theistic God showed a greater inclination toward militarism, while no significant differences were found regarding pacification. Catholic students were those who least despised war, and those identifying as atheists or non-theistic religions were the least likely to believe in the existence of a just world. These findings provide a framework for understanding the perspectives of this age group.

description: This project contains the replication package for the paper titled "<b>The
Economic Impact of Uncertainty about U.S. Regulations of the Energy Sector</b>."<br><br>Abstract: This paper examines the economic impact of uncertainty surrounding U.S. regulatory policies of the energy sector. We first construct a monthly-frequency measure of regulatory uncertainty related to oil and gas production using natural language processing on over 600,000 U.S. newspaper articles published from 1985 to 2021. We then conduct empirical analysis via structural VAR models with the constructed oil regulatory uncertainty index, oil market variables, and aggregate economic data. The impulse response functions suggest that an increase in oil regulatory uncertainty reduces oil production and drilling activity and negatively affects national and state-level economic outcomes.
