Techniques for establishing new behaviors are shaping (successive approximations), chaining, and fading. Shaping is the establishment of a final behavior (one that the person does not possess or that very rarely emits) through the differential reinforcement of behaviors that are increasingly similar or close to it. Generally, shaping refers to differential reinforcement of changes gradual changes in the topography of a behavior, but it can also refer to differential reinforcement of gradual changes in other characteristics of the behavior such as frequency, duration, latency or magnitude, or differential reinforcement of gradual changes in the product of the behavior (for example , number of exercises solved).

Answer:
Genetic drift is the change or mutation in the gene pool over generations. It can take several generations for a genetic drift to take place in a community. But if the population of that generation is smaller, there are higher chances that the genetic drift would occur over the next very generations. Any mutilations that disrupts the natural course of genetic transfer can cause genetic drift to take place in those species.
Answer:
First-hand ethnographic fieldwork
Explanation:
Ethnography is the detailed account of a society and its culture by observing the social interactions that people have. This gives us an accurate description of a society and its culture as it not influenced by outside factors.
Here, Maria is studying the the lives of women in coffee farming communities in Brazil. She is observing them directly and making sure her presence does not influence their interactions. She is also doing this herself which means her research will not be affected by someone else's perspective.
Hence, she is using the strategy of first-hand ethnographic fieldwork.
