Here's a question with three different answers. The first answer is derived from arithmetic. The second comes from common sense. The third is based on psychology.

Two centuries ago, Napoleon Bonaparte sent his armies into Spain to overthrow a monarch who had once been a French ally. Napoleon, who believed he was touched by the hand of destiny, predicted his troops would be welcomed as liberators by ordinary Spaniards. He was wrong. The resulting Peninsular War from 1808 to 1814 seriously undermined French prestige, handed Napoleon a stinging defeat and produced a raft of unanticipated consequences that included the outbreak of deadly civil wars....

What do the war in Iraq, your Christmas shopping and this week's Thanksgiving dinner have in common?

According to conventional wisdom, front-runners win presidential nominations. Democrats and Republicans who start the race for a presidential nomination with the largest amount of money and the best poll numbers are supposed to be the ones most likely to walk away with victory months later.

Three horrors await Americans who get behind the wheel of a car for a family road trip this summer: the spiraling price of gas, the usual choruses of "are-we-there-yet?" -- and the road rage of fellow drivers.

With America divided right down the middle for the third presidential election in a row, most people would not be surprised to hear that Democratic and Republican partisans perceive a widening gap between their presidential choices. In 2004, for example, die-hards in both parties felt that the...

With displacement at a record high, governments around the world are looking for ways to jumpstart, expand, or maximize the impact of their refugee resettlement programs. Yet the evidence base regarding the effectiveness of such programs is particularly thin. This report maps the monitoring and evaluation gaps that exist and identifies areas where further research could help inform policymakers' actions.

Marking the release of an MPI Europe report commissioned as part of the EU-FRANK project, this webinar examines critical gaps in the research and evaluation of refugee resettlement programs and recommendations for improving evidence gathering and knowledge sharing between resettlement countries. 

Following the 2015­–16 crisis that saw record numbers of refugees arrive in Europe, policymakers have shown interest in creating managed, legal alternatives to the dangerous, unauthorized journeys many asylum seekers make. While these discussions should be informed by an understanding of current pathways and protection channels, it is "nearly impossible" to know how protection seekers enter and what legal channels are available to them, as this MPI Europe report explains.

As maritime arrivals climbed in 2015, EU policymakers struggled to mount a coordinated response. A range of ad hoc crisis-response tools emerged, but many officials worry that if another migration emergency were to hit Europe, the European Union may still be unprepared. This report traces the evolution of the EU response to the 2015–16 crisis and lays out recommendations to lock in progress and shore up weaknesses.

European countries have ramped up their investments in helping refugees find work and integrate into society. Yet little hard evidence exists of what programs and policies work best. This report proposes a new framework for thinking smartly about integration programming, using cost-benefit analysis to look beyond short-term, economic outcomes to also measure indirect benefits through a social-value concept.

EU policy debates about moving asylum seekers from overburdened frontline countries, such as Greece and Italy, to other Member States rarely consider how migrants form and act on preferences for certain destinations—and how difficult it may be to change these views. This issue brief explores decision-making among migrants in Greece, including how living conditions, jobs, and legal status factor in.

As EU Member States struggle to deliver on the European Union's call to expand channels for foreign workers, they should focus more on attracting the middle- and low-skilled third-country nationals needed by the labor market yet for whom few opportunities for admission exist. They also would do well to consider their migration policies in light of labor market, foreign policy, and development objectives, rather than as a means to reduce irregular migration, this report cautions.

Six million immigrant workers are at the frontlines of keeping U.S. residents healthy and fed during the COVID-19 pandemic, representing disproportionate shares of physicians, home health aides, and retail-store pharmacists, for example. They also are over-represented in sectors most immediately devastated by mass layoffs, yet many will have limited access to safety-net systems and to federal relief, as this fact sheet details.

Marking the release of an MPI report, this webinar examines the challenges and successes major host countries in Europe and North America are experiencing in providing high-quality early childhood education and care (ECEC) services for children from refugee and asylum seeker families.

Experts on this webinar discussed the effects of trauma on the development of young refugee children, and how early child-care programs can address these traumatic experiences. The discussion featured practical strategies that child-care providers in Canada are implementing to support refugee children and families. 

Nearly half of immigrant adults arriving in the U.S. since 2011 have a college degree—a far higher share than a quarter-century ago, when just 27 percent did. This striking but little noted shift in the composition of recent immigrant flows, driven in part by rising migration from Asia, comes as some policymakers press for a "merit-based" immigration system. This fact sheet examines rising human capital at U.S. and state levels.

A recent MPI study reveals that 48 percent of recent immigrants to the United States were college graduates, a sharp increase over earlier periods. How can the United States better leverage this brain gain? This commentary outlines some policies that could allow the United States to more fully utilize the professional and academic credentials that highly skilled immigrants have, for their benefit and that of the U.S. economy.

By winding down DACA over six months, President Trump may have addressed a short-term political dilemma. But this action ensures debate will rage on in search of a lasting solution, as many in Congress and beyond recognize the loss of work authorization and deportation relief will affect not only DACA recipients and their families, but also employers, universities, and communities alike, as this commentary explores.

To successfully integrate, immigrants and refugees need a variety of skills and knowledge—from English proficiency to understanding how school systems and local services work. Yet the adult education programs in place to support them have narrowed in scope. This policy brief proposes a new instructional model, English Plus Integration, to help states more comprehensively meet the diverse needs of their adult immigrant learners.

Over the last several years it has become clear that higher order assemblies on membranes, exemplified by signalosomes, are a paradigm for the regulation of many membrane signaling processes. We have recently combined two-color direct stochastic optical reconstruction microscopy (dSTORM) with the (Clus-DoC) algorithm that combines cluster detection and colocalization analysis to observe the organization of 5-lipoxygenase (5-LO) and 5-lipoxygenase–activating protein (FLAP) into higher order assemblies on the nuclear envelope of mast cells; these assemblies were linked to leukotriene (LT) C4 production. In this study we investigated whether higher order assemblies of 5-LO and FLAP included cytosolic phospholipase A2 (cPLA2) and were linked to LTB4 production in murine neutrophils. Using two- and three-color dSTORM supported by fluorescence lifetime imaging microscopy we identified higher order assemblies containing 40 molecules (median) (IQR: 23, 87) of 5-LO, and 53 molecules (62, 156) of FLAP monomer. 98 (18, 154) molecules of cPLA2 were clustered with 5-LO, and 77 (33, 114) molecules of cPLA2 were associated with FLAP. These assemblies were tightly linked to LTB4 formation. The activation-dependent close associations of cPLA2, FLAP, and 5-LO in higher order assemblies on the nuclear envelope support a model in which arachidonic acid is generated by cPLA2 in apposition to FLAP, facilitating its transfer to 5-LO to initiate LT synthesis.

In Staphylococcus aureus–caused endocarditis, the pathogen secretes staphylocoagulase (SC), thereby activating human prothrombin (ProT) and evading immune clearance. A previous structural comparison of the SC(1–325) fragment bound to thrombin and its inactive precursor prethrombin 2 has indicated that SC activates ProT by inserting its N-terminal dipeptide Ile1-Val2 into the ProT Ile16 pocket, forming a salt bridge with ProT's Asp194, thereby stabilizing the active conformation. We hypothesized that these N-terminal SC residues modulate ProT binding and activation. Here, we generated labeled SC(1–246) as a probe for competitively defining the affinities of N-terminal SC(1–246) variants preselected by modeling. Using ProT(R155Q,R271Q,R284Q) (ProTQQQ), a variant refractory to prothrombinase- or thrombin-mediated cleavage, we observed variant affinities between ∼1 and 650 nm and activation potencies ranging from 1.8-fold that of WT SC(1–246) to complete loss of function. Substrate binding to ProTQQQ caused allosteric tightening of the affinity of most SC(1–246) variants, consistent with zymogen activation through occupation of the specificity pocket. Conservative changes at positions 1 and 2 were well-tolerated, with Val1-Val2, Ile1-Ala2, and Leu1-Val2 variants exhibiting ProTQQQ affinity and activation potency comparable with WT SC(1–246). Weaker binding variants typically had reduced activation rates, although at near-saturating ProTQQQ levels, several variants exhibited limiting rates similar to or higher than that of WT SC(1–246). The Ile16 pocket in ProTQQQ appears to favor nonpolar, nonaromatic residues at SC positions 1 and 2. Our results suggest that SC variants other than WT Ile1-Val2-Thr3 might emerge with similar ProT-activating efficiency.

My first exposure to Robert Macfarlane happened a year ago when I picked up a battered copy of The Wild Places in order to shelve it. Instead, I checked it out from my branch and stayed up past midnight to read it. Thanks to Macfarlane, I was exposed to Roger Deakin's Wild Wood and Notes from Walnut Tree Farm. I found photos of Walnut Tree Farm, the late Deakin's house, much visited by Macfarlane, while searching for more information about both of them online.

I am from probably the last generation of American children to be raised on English children's books. I know that there is a generation of Quidditch-playing adults that were weaned on the Harry Potter books of British-born J. K. Rowling. While the Harry Potter books are gripping, they lack an essential British characteristic shared by many successful authors of British children's books:

• Rudyard Kipling - the two Puck of Pook's Hill books
• Rosemary Sucliff - all of her books
• Elizabeth Goudge - Rowling helped get Linnets & Valerians and The Little White Horse republished
• L. M. Boston - the Greene Knowe series
• William Mayne
• Robert Westall
• Diana Wynne Jones - the British landscape of an alternative Britain
• J. R. R. Tolkein -The Hobbit
• Kenneth Graham - The Wind in the Willows
• T. H. White - The Once and Future King
• Susan Cooper - The Dark is Rising series

Macfarlane likes to walk. In The Wild Places, he visits mountains, woods, water. In The Old Ways, he follows the ancient paths that cross the British isles, that go through wood, by the sea shore, and over the downs. His England (and Scotland) however, is multilayered; he is aware not only of the physical landscape surrounding him but of the history of the land through which he walks. A walk take him from point A to point B in physical space, as well as through centuries of time. In his author's note, Macafarlane observes:

"It is an exploration of the ghosts and voices that haunt ancient paths, of the tales that tracks keep and tell, of pilgrimage and trespass, of songlines and their singers and of the strange continents that exist within countries" (p.xi).

While Americans are criticized for being such a highly mobile society, humans have always traveled. Early hunter-gatherers did not stay in one place, but roamed within a fairly wide territory. The early sea-farers such as the Phoenicians, the Greeks, the Carthaginians, the Romans (marine archaeology has shown that they sailed more than we have associated with them) and the Vikings all traveled the roads of the sea. The medieval Crusades were holy wars, but they were also the mass movement of men, women, and children walking across Europe, then by boat from southern Italian ports to the Holy Land. Within Europe itself, bands of pilgrims walked from their homes along the tracks to Canterbury or St. James de Campostela. Merchants in ancient and medieval times traveled in caravans along the land and sea routes of the Silk Roads.

The difference between the modern traveler of today and that of the past is that travelers today are less exposed to the world around them. When you are encased in a plane or enclosed in a fast car, you lose awareness of the physical world outside of you. The electronic devices that we use to distract ourselves during our journeys - our DVD players, Ipods, tablets and ebook readers, all cut us off from the landscape and  fellow travelers around us. Macfarlane deliberately chooses to travel on foot (and by small boat) to connect with the physical world around him during his modern secular pilgrimage.

My first exposure to Lucy Maria Boston's Green Knowe series came when my older brother took a an introduction to children's literature class during his first year in college. He was required to read The Children of Green Knowe. I found the copy that he had checked out of our village library, loved it, and worked my way through the other books in the series:

Two weeks ago, some friends and I toured Lucy Boston's house and garden. My friend Val had read Boston's books; her husband Dave hadn't heard of Boston but wanted to see the old house. We took a train from London to the nearby town of Huntington (pop 10,000), then a short taxi ride to Hemingford Grey (pop.230), a quaint small village on the River Ouse.

Here are photos of the town's main or high street:

Since we were early for our 2 PM house tour, we decided to explore the gardens. Lucy talks about designing and building the gardens in her memoir Memory in a House, which also contains some black and white photos of the gardens back when she published the book. However, I did not realize until her daughter-in-law Diana Boston gave us the tour how much of the gardens Lucy build from scratch. Apparently most of the yard was just meadow until she set to work.

What stunned me, Val, and Dave was how large the gardens were in size. We split up in the gardens, and they saw only the more cultivated side:

BRUSSELS — While the European Union has called on Member States to expand channels for foreign workers as a way to meet labour market needs and potentially tackle spontaneous migration, they have struggled to deliver on this pledge. To date, policies have focused more on attracting high-skilled workers, but less attention has been paid to admission of low- or middle-skilled nationals. Policymakers would do well not to overestimate the potential of legal channels to reduce irregular migration.

WASHINGTON — Rapid arrivals of humanitarian migrants in Europe and North America have been matched by an equally unprecedented outpouring of public support. As offers to volunteer and donate pour in, many have asked whether this generosity can be harnessed to ease pressures on overburdened receiving communities and service providers. But using volunteers to meet the longer-term integration needs of resettled refugees and recognized asylum seekers is not an automatic salve: it requires thoughtful training and investment to be effective.

WASHINGTON — Asylum seekers and refugees who arrived in Germany in the leadup to and during the 2015-16 European migration crisis have integrated into the labor market at a slightly faster rate than previous refugee cohorts, a Migration Policy Institute (MPI) report finds.

WASHINGTON — The Migration Policy Institute (MPI) today published the annual update to its data-rich article, Frequently Requested Statistics on Immigrants and Immigration in the United States, offering readers a wealth of information that can help inform understanding about an issue that is the subject of much conversation.

Findings will be discussed during 25 February MPI Europe – SVR webinar

Brussels and Gütersloh, 05.03.2020 — Anticipated reform of the Common European Asylum System (CEAS), which was high on the agenda as nearly 2 million asylum seekers arrived at Europe’s door in 2015-16, quickly fell victim to EU Member State competing views on what constitutes equal burden-sharing, domestic politics around migration and the urgency of first addressing overtaxed national asylum systems.

WASHINGTON — Six million immigrant workers are at the frontlines of keeping U.S. residents healthy, safe and fed during the COVID-19 pandemic, according to a Migration Policy Institute (MPI) analysis of U.S. Census Bureau data issued today. While the foreign born represented 17 percent of the 156 million civilians working in 2018, they account for larger shares in pandemic-response frontline occupations: 29 percent of all physicians in the United States, 38 percent of home health aides and 23 percent of retail-store pharmacists, for example.

WASHINGTON — The U.S. immigration system was dramatically reshaped by the terrorist attacks of September 11, 2001, which shone a harsh spotlight on weaknesses in visa and immigration screening processes. From the creation of the Department of Homeland Security (DHS) to expanded national security protections in immigration and tourism policies, countless changes in the immigration arena have unfolded over the past 19 years.
