What is causal relationships transferability in health research?4 answersCausal relationships transferability in health research refers to the ability to apply learned causal models from one environment to another with similar underlying dynamics. This concept is crucial in health science, where observational datasets are common, and causal relationships are sought to prevent or mitigate diseases. Transfer learning frameworks using causal models can aid in transferring knowledge between health-related scenarios with comparable causal structures. While randomized control trials (RCTs) are the gold standard for establishing causality, observational studies can benefit from methods like propensity score matching to address confounding factors and enhance causal inference. By leveraging causal inference frameworks, researchers can enhance the value of observational clinical data in understanding the effects of treatments and interventions in health science.
What are the principal theories in anthropology of health?5 answersThe principal theories in the anthropology of health encompass various perspectives. These include the holistic approach of anthropology, which emphasizes the interconnectedness of political, economic, cultural, and interspecies factors in global health issues. Additionally, the field has evolved through historical studies, highlighting ecological, interpretive, and critical theoretical approaches that enrich the understanding of health and illness processes. Critical Medical Anthropology contributes significant theoretical concepts such as biopower/discipline, structural violence, and identity politics, shedding light on human behaviors related to health and illness, and impacting theory, research, and public health practices. Furthermore, the Anthropology of Health offers interpretive and critical perspectives, as seen in the works of Kleinman and Menendez, which provide insights into cultural factors shaping health beliefs and practices, supporting culturally congruent healthcare approaches.
How do people build causal graphs?4 answersBuilding causal graphs involves a laborious process that requires researchers to discuss with clinicians, review relevant medical literature, and encode common and medical knowledge. Large language models (LLMs) can be used to automatically score edges in potential graphs by encoding this knowledge. However, LLMs can be brittle to the choice of probing words, context, and prompts used by the user. To complement causal graph development, LLMs can be evaluated as a useful tool. Another approach involves using data, constraints, and graph parameters to construct a causal graph, generating an interactive display interface, and refining the graph using the interface. Additionally, a novel graph-based method and an EMR repository can be used to construct causal graphs between medical conditions, resulting in improved precision compared to existing methods. In the context of news, causal knowledge graphs can be constructed by extracting causal relations from text and clustering arguments using topic modeling.
How to do causal inference with machine learning models?4 answersCausal inference with machine learning models can be done by combining predictive machine learning models with analytical estimations of average treatment effects. This approach allows for the utilization of any predictive model for causal inference, making it adaptable to existing systems. The process involves estimating the average treatment effect of an intervention on predictors, determining the causal relationship between the intervention and a wide range of variables. Artificial samples are then created and evaluated using the predictive model to link interventions and outcomes, providing measurements of uncertainty. Simulations are performed using the predictive model to compute measurements of confidence and compare the effects of specific treatments. This approach can also be adapted to privacy-preserving federated learning environments, where training data is distributed across multiple datasets.
How to understand causal responsibility?5 answersCausal responsibility refers to the responsibility that arises from an agent's direct contribution to a particular outcome, regardless of their intentions or beliefs. It is a fundamental form of responsibility in both moral and legal reasoning, where acts and intentional states are considered in determining moral blameworthiness and legal offenses. The concept of responsibility is closely related to the idea of being able to respond and being accountable for one's actions or states of character. In economics, perceptions of responsibility are influenced by the notion of causal responsibility, which objectively captures the causal importance of an individual's actions in bringing about an event. Understanding causal responsibility is important in decision-making processes, as it helps identify critical actions and attribute responsibility to decision-makers. By considering causal dependencies and the ability to manipulate responsibility, responsibility attribution methods can be developed to accurately assess an agent's degree of responsibility.
A.What is meant by the term ‘causality’ in public health?3 answersCausality in public health refers to the relationship between a cause and its effect on health outcomes. It involves understanding how changes in one variable can lead to changes in another variable, specifically in the context of public health. Causal inference is important in public health research as it helps identify the impact of interventions, policies, or exposures on health outcomes. It requires careful consideration of study design, data analysis, and the use of appropriate statistical methods to establish causal relationships. Several papers discuss the concept of causality in public health, including the importance of potential outcomes, causal estimands, causal analysis with propensity scores, and the use of directed acyclic graphs (DAGs) to identify confounders.
