After more than a year’s hard work by Dr. Venkataram and his group, I am happy that IADVL is now publishing these guidelines written by IADVL members for IADVL members in a special issue of IJDVL. Carefully chosen authors, who are pioneers in their own fields, have contributed chapters for this issue. They have taken many pains to author these chapters and I individually congratulate them for t...

The superimposed pair of spiral galaxies comprising NGC 3314 ooers a unique opportunity to trace the dust properties in a spiral galaxy. We analyze multicolor HST imaging, supported by ground-based near-IR imaging and ber-array spectroscopy to measure dust extinction in the foreground Sc galaxy NGC 3314A, which is backlit by the Sb system NGC 3314B. The superposition allows us to measure extinc...

We show that the full version of the so-called ‘rural hospital theorem’ generalizes to many-to-many matching problems where agents on both sides of the problem have substitutable and weakly separable preferences. We also show that when agents’ preferences satisfy substitutability, the domain of weakly separable pref-

In this note, I extend the work of Echenique (forthcoming) to show that a model of many-to-many matching with contracts may be embedded into a model of many-tomany matching with wage bargaining whenever (1) all agents’ preferences are substitutable and (2) the matching with contracts model is unitary, in the sense that every contractual relationship between a given firm–worker pair is specified...

If you really want to be smarter, reading can be one of the lots ways to evoke and realize. Many people who like reading will have more knowledge and experiences. Reading can be a way to gain information from economics, politics, science, fiction, literature, religion, and many others. As one of the part of book categories, though i walk through the valley always becomes the most wanted book. M...

Context: Existing hospitalization ratios for COVID-19 typically use case counts in the denominator, which problematically underestimates total infections because asymptomatic and mildly infected persons rarely get tested. As a result, surge models that rely on to forecast hospital demand may be inaccurately influencing policy decision-maker action. Objective: Based SARS-CoV-2 prevalence data de...
