Why do attributions of specific events matter for the relevant policy preferences people hold?
4 answers
Attributions of specific events matter for the policy preferences people hold because they shape how individuals perceive the causes of phenomena like extreme weather events and obesity, influencing their policy stances. Research highlights that individuals tend to attribute causes to controllable or uncontrollable components based on group identity and individual characteristics. Understanding the cognitive and motivational processes underlying laypeople's attributions for extreme events is crucial for effective communication about climate change. Additionally, attribution science aims to enhance understanding of causal links between the Earth System and society, informing climate-related risk management and adaptation policies. This integration of attributions into policy discussions can lead to more informed decision-making and effective strategies to address losses and damages associated with climate change impacts.

Does lower productivity create suply chain shoratge?
5 answers
Lower productivity can indeed lead to supply chain shortages. Research suggests that in the context of supplier firms, traditional suppliers tend to exhibit lower levels of productivity compared to final firms. However, advanced suppliers, who export a significant portion of their production and engage in innovations, can achieve productivity levels equal to or even higher than final firms, mitigating shortages. Additionally, the selection of lower-cost firms as suppliers in an economy with a high share of intermediate goods can boost aggregate productivity and reduce the risk of shortages in the supply chain. Factors like poor logistics and transportation facilities have been identified as critical barriers to productivity in dairy supply chains, potentially leading to shortages in milk processing units in certain regions.

How has the concept of petty theft evolved over time in England?
5 answers
The evolution of petty theft in England has been influenced by various factors over time. In the thirteenth century, a statute enacted during the reign of Edward I in 1278 defined the threshold for larceny as 12d., leading to significant developments in the treatment of petty theft, including the promotion of penal imprisonment and the increased role of trial juries in determining verdicts. In the early modern period, female involvement in property crime was often perceived as relatively insignificant, leading to the characterization of women's thefts as petty criminality, with assumptions of women being less criminally dangerous and more likely to receive generosity and clemency within the criminal justice system. However, historical accounts have predominantly focused on serious crimes, such as felony, murder, and grand larceny, overshadowing the attention given to petty crimes like theft.
