Uranium isotope constraints on the transport time of Asian dust to the North Pacific Ocean: Implication for provenance and iron supply
<p>This dataset presents uranium isotope data covering a 300,000-year period retrieved from Ocean Drilling Program site 1209B in the North Pacific Ocean. Additionally, it incorporates uranium-neodymium isotope data sourced from multiple deserts in China, providing a comprehensive reexamination of the origin of dust in the North Pacific region.</p>

The scenarios are developed as part of the <a href="http://www.engage-climate.org/" target="_blank" rel="noopener">ENGAGE</a> project, and explore a wide set of dedicated feasibility assumptions along the institutional, technological, geophysical, and socio-cultural dimensions. In terms of mitigation ambition, the study follows the "net-zero budget" approach from <a href="https://www.nature.com/articles/s41558-021-01215-2" target="_blank" rel="noopener">Riahi et al. 2021</a> and contrasts both a below 2°C scenario (defined as 1000 Gt CO2 from 2018 until reaching net-zero CO2 emissions globally), and a scenario exploring the lowest possible peak temperature (aiming for a 550 Gt CO2 net-zero budget). </p> <h3><strong>Author Contributions</strong></h3> <p>C.B., E.B. and K.R. designed the study with input by L.D., E.K., G.L., B.v.R., R.S., D.v.V. and Z.V.; E.B. and C.B. prepared the governance input data for the IAMs; C.B., E.B., L.D., B.v.R., L.A.R., L.B.B., H.-S.d.B., V.D., F.F., D.F., O.F., S.F., K.K., V.K., R.M., P.R., R.S., D.S., I.T. and Z.V. produced the IAM scenario results; R.C., G.I. and N.H. provided a review of results and framing; R.D.L. and J.R. provided temperature probabilities as a function of carbon budgets; C.B. performed the data analysis and produced the plots with input by E.B. and L.D.; C.B. wrote the first draft and all authors contributed to writing the paper.</p> <h3><strong>Acknowledgments</strong></h3> <p>This research received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement number 821471 (ENGAGE) (C.B., E.B., L.D., G.L., B.v.R., L.A.R., L.B.B., H.-S.d.B., R.C., V.D., F.F., D.F., O.F., S.F., N.H., G.I., K.K., V.K., E.K., R.D.L., R.M., P.R., J.R., R.S., D.S., I.T., D.v.V., Z.V., K.R.).

Entrepreneurial-intention constraint model: A comparative analysis among post-graduate management students in India, Singapore and Malaysia
<p>Although literature on entrepreneurship has increasingly focused on intention based<br> models, not much emphasis has been laid on understanding the combined effect of<br> contextual and situational factors along with support of university environment on the<br> formation of entrepreneurial intention among students. In an effort to make up for this<br> shortfall, by taking Theory of Planned Behavior as basic framework, the present study<br> seeks to understand the influence of three of the most important factors, viz. (a)<br> endogenous barriers, (b) exogenous environment, and (c) university environment and<br> support on the entrepreneurial intention among management students. The study sample<br> consisted of 1,097 students, wherein 526 students were from India, 252 from Singapore,<br> and 319 were from Malaysia. The results indicates that along with positive attitude and<br> perceived behavioral control that directly influences entrepreneurial intention, university<br> environment and support and exogenous environment also have an indirect but significant<br> impact on shaping of entrepreneurial intention among students. With this, it was<br> found that exogenous environment was found to have a negative relationship with both<br> attitude towards behavior and perceived behavioral control for all three countries.</p>
