AI Article Synopsis
- This study explores how genetic variation influences attitudes towards foreign policy, diverging from traditional explanations that focus mainly on ideological and demographic factors.
- Using data from the Minnesota Twin Family Study, the research finds that genetics accounts for a moderate portion of individual differences in foreign policy preferences, such as being hawkish or dovish.
- The study also suggests that foreign policy preferences might stem from a shared genetic basis with political ideology, indicating that ideology could be a key factor in how genetics impact foreign policy views.
Article Abstract
Attitudes towards foreign policy have typically been explained by ideological and demographic factors. We approach this study from a different perspective and ex amine the extent to which foreign policy preferences correspond to genetic variation. Using data from the Minnesota Twin Family Study, we show that a moderate share of individual differences in the degree to which one's foreign policy preferences are hawkish or dovish can be attributed to genetic variation. We also show, based on a bivariate twin model, that foreign policy preferences share a common genetic source of variation with political ideology. This result presents the possibility that ideology may be the causal pathway through which genes affect foreign policy preferences.

This article examines the landscape of Science, Technology, and Innovation policies in Central America, focusing on Nicaragua, Guatemala, Honduras, and El Salvador. These nations face significant challenges in leveraging STI for sustainable development, including financial constraints and limited resources. Additionally, Central America struggles with systemic issues such as corruption, violence, and high levels of emigration, further complicating efforts to advance STI.

Introduction: The 2015 American Thyroid Association guidelines recommend de-escalating surgical treatment for papillary thyroid cancer (PTC). We hypothesize that the Dutch PTC population might differ due to a restrictive diagnostic policy that mainly selects symptomatic and palpable thyroid nodules for further diagnostics, potentially selecting relatively more aggressive tumors. We aimed to describe the Dutch PTC population because differences in populations can have consequences for the adoption of foreign guidelines.

Carbon peaking is of great significance for China to achieve the "dual carbon" target goal and promote the green transformation of the economy and society. Based on the improved STIRPAT model, to analyze the main factors affecting carbon emissions in Fujian Province, we set up three scenarios and predicted the carbon emissions in Fujian Province from 2022 to 2035 using the hybrid CNN-LSTM neural network model. The results showed that ① Population, GDP per capita, and industrial structure positively drove carbon emissions in Fujian Province, while energy intensity, energy structure, and foreign trade degree negatively drove them.

Maintaining the stability of foreign trade in an uncertain environment is crucial to building a new development pattern. By combing through the existing literature, this paper analyzes the impact of economic policy uncertainty on enterprise export recovery from the perspective of market integration. Firstly, theoretical analysis shows that economic policy uncertainty is expected to attenuate enterprise export recovery levels by amplifying export transaction costs.

Background: Tuberculosis vaccine trials using disease as the primary endpoint are large, time consuming, and expensive. An earlier immunological measure of the protection against disease would accelerate tuberculosis vaccine development. We aimed to assess whether the effectiveness of the Bacillus Calmette-Guérin (BCG) vaccine for prevention of Mycobacterium tuberculosis infection was consistent with that for prevention of tuberculosis disease.
