Key Questions

This introductory chapter lays out the key questions of the book. It explains the background assumptions at play and the key philosophical commitments supporting the different arguments in the book. This chapter also explains the key arguments of the following chapters and how they come together to support a partial theory of immigrations that avoids both open borders and complete control of immigration on the part of states. It also explains how the theoretical framework defended in the first part of the book affects the applied questions pursued in the second part of the book, such as the ethics of asylum, family migration schemes, the brain drain, and immigration enforcement.

AbstractThis article focuses on two questions regarding the movement of persons across international borders: (1) do states have a right to unilaterally control their borders; and (2) if they do, are migration arrangements simply immune to moral considerations? Unlike open borders theorists, I answer the first question in the affirmative. However, I answer the second question in the negative. More specifically, I argue that states have a negative duty to exclude prospective immigrants whose departure could be expected to contribute to severe deprivation in their countries of origin. Countries have a right to unilaterally control their borders, but their exercise of this right is constrained by the demands of morality.

Key Questions

The term “brain drain” dominates popular discourse on high-skilled migration, and for this reason, we use it in this article. However, as Harry Johnson noted, it is a loaded phrase implying serious loss. It is far from clear that such a loss actually occurs in practice; indeed, there is an increasing recognition of the possible benefits that skilled migration can offer both for migrants and for sending countries. This paper builds upon a recent wave of empirical research to answer eight key questions underlying much of the brain drain debate: 1) What is brain drain? 2) Why should economists care about it? 3) Is brain drain increasing? 4) Is there a positive relationship between skilled and unskilled migration? 5) What makes brain drain more likely? 6) Does brain gain exist? 7) Do high-skilled workers remit, invest, and share knowledge back home? 8) What do we know about the fiscal and production externalities of brain drain?

Bow Tie

In the past decades, neuroscientists and clinicians have collected a considerable amount of data and drastically increased our knowledge about the mapping of language in the brain. The emerging picture from the accumulated knowledge is that there are complex and combinatorial relationships between language functions and anatomical brain regions. Understanding the underlying principles of this complex mapping is of paramount importance for the identification of the brain signature of language and Neuro-Clinical signatures that explain language impairments and predict language recovery after stroke. We review recent attempts to addresses this question of language-brain mapping. We introduce the different concepts of mapping (from diffeomorphic one-to-one mapping to many-to-many mapping). We build those different forms of mapping to derive a theoretical framework where the current principles of brain architectures including redundancy, degeneracy, pluri-potentiality and bow-tie network are described.

Key Questions

Vitamin D and cognition is a popular association, which led to a remarkable body of literature data in the past 50 years. The brain can synthesize, catabolize, and receive Vitamin D, which has been proved to regulate many cellular processes in neurons and microglia. Vitamin D helps synaptic plasticity and neurotransmission in dopaminergic neural circuits and exerts anti-inflammatory and neuroprotective activities within the brain by reducing the synthesis of pro-inflammatory cytokines and the oxidative stress load. Further, Vitamin D action in the brain has been related to the clearance of amyloid plaques, which represent a feature of Alzheimer Disease (AD), by the immune cell. Based on these considerations, many studies have investigated the role of circulating Vitamin D levels in patients affected by a cognitive decline to assess Vitamin D’s eventual role as a biomarker or a risk factor in AD. An association between low Vitamin D levels and the onset and progression of AD has been reported, and some interventional studies to evaluate the role of Vitamin D in preventing AD onset have been performed. However, many pitfalls affected the studies available, including substantial discrepancies in the methods used and the lack of standardized data. Despite many studies, it remains unclear whether Vitamin D can have a role in cognitive decline and AD. This narrative review aims to answer two key questions: whether Vitamin D can be used as a reliable tool for diagnosing, predicting prognosis and response to treatment in AD patients, and whether it is a modifiable risk factor for preventing AD onset.
