Stable isotope evidence for pre-colonial maize agriculture and animal management in the Bolivian Amazon In the Bolivian Amazon, analyses of preserved human bone collagen show evidence of maize staple diets between ce 700 and 1400, as well as management of muscovy ducks, one of the few animals ...
Here, we provide verifiable evidence that interdisciplinarity is statistically significantly and positively associated with research impact by focusing on highly cited paper clusters known as the research fronts (RFs). Interdisciplinarity is uniquely operationalised as the effective number of distinct ...
generalisation of the results and to ensure that the findings are representative of the very heterogeneous AEC sector, a very targeted sampling method was used to ensure that (i) participants came from various parts across the AEC sectors, and thus are representative of the entire spectrum, i.e...

In situ Hf isotopic analysis of oxide-type U-bearing accessory minerals was reviewed with NEPTUNE multiple-collector inductively coupled plasma-mass spectrometry (MC-ICPMS) and a 193nm excimer laser ablation system. RESULTS Combined with relevant research work in recent years, the development history...
Second, even more worrying, were the results of fieldwork in the global south carried out by this cohort of graduate students in the 1970s and 1980s. They produced evidence that bad governance, corruption, skewed access to resources (land, water, etc.), and lack of investment ...
The results of the study showed that students using Math Expressions were performing at higher levels of math achievement when compared with students using similar programs. Math Expressions yielded substantial increases in test scores as well as on broader measures of understanding. FIGURE 1. Test Sc...

researcher, John Ioannidis, a prominent scholar on reproducibility in science, has pointed out that the importance of reproducibility does not have to do with ensuring the ‘correctness’ of results, but rather with ensuring the transparency of exactly what was done in a given line of research1....
