農作物の残渣の燃焼を規制する 官僚を奨励すれば 南アジアで大気汚染を 減らすことができます このアプローチは将来の燃焼を抑止し,大気汚染に関連した子供の死亡率を大幅に低下させます.
科学分野:
- 環境科学
- 公衆衛生
- 環境政策
背景:
- 南アジアの大気汚染は 大きな健康危機であり 毎年200万人の死因となっています
- 農作物の残渣を燃やすことは冬のピーク汚染に大きく寄与する.
- 燃焼を禁止する既存の規制は広く無視されており,新しい解決策が必要になっています.
研究 の 目的:
- 農作物の残渣の燃焼を軽減できるかを調査する.
- 火災発生と汚染に対する官僚のインセンティブの影響を定量化する.
- 農作物の燃焼による大気汚染の公衆衛生上の影響を評価する.
主な方法:
- 風,火災,健康に関する10年間の衛星データの分析
- 官僚の動機付けと燃焼の行動を 関連付けるためのエコノメトリック分析です
- 汚染の健康への影響を推定するための大気モデリング.
主要な成果:
- 農作物の燃焼は,汚染が外部に向けられた場合15%増加し,官僚自身の管轄区域に影響を与えると14.5%減少します.
- 動機付けと官僚的な能力は これらの効果を強める.
- 官僚の行動により 将来の燃焼は13%減少し 汚染被曝量の増加ごとに 幼児死亡率の増加は1000人に30~36人
結論:
- 官僚の奨励は作物の残渣の燃焼を制御するのに有効です.
- ターゲットを絞ったインセンティブは 環境管理と公衆衛生の成果を向上させることができます
- 農作物の燃焼問題は 解決できない問題ではなく 政策的な介入で解決できる問題です

01:57Adaptations that Reduce Water Loss
25.1K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

01:46The Calvin Benson Cycle
4.4K
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

01:18Incentive Theory: Pull Theory of Motivation
379
Incentive theory, or the "pull theory" of motivation, suggests that external rewards primarily drive behavior. Individuals are motivated to engage in activities when they anticipate a desirable outcome. This is why people often work hard for promotions or study intensively to achieve high grades. These incentives can be tangible, physical rewards such as money or promotions, or intangible, non-physical rewards like praise and social recognition.
