Revisiting aspiration and ability in international migration

It is a refreshingly simple thought that migration is the combined result of two factors: the aspiration to migrate and the ability to migrate. Without having to resort to overly structural or individualistic explanations, this analytical distinction helps disentangle complex questions around why some people migrate but others do not. Still, aspiration and ability raise their own thorny theoretical and methodological questions. To begin with, what does it mean to have migration aspirations? How can such concepts be objects of empirical research? And is it meaningful to say that individuals possess the ability to migrate if their preference is to stay? The aspiration/ability model was originally proposed in this journal and has since been diversely applied and adapted. In this article, we look back at more than a decade of research to examine a series of theoretical and empirical developments related to the aspiration/ability model and its extensions. We identify two-step approaches as a class of analytical frameworks that share the basic logic of the aspiration/ability model. Covering expansive theoretical, methodological and empirical ground, we seek to lay a foundation for new research on global migration in its diverse forms

Shop 'Till We Drop: A Historical and Policy Analysis of Retail Goods Movement in the United States

The movement of retail goods is central to modern economies and is a significantbut understudiedfraction of our overall energy footprint. Thus, we propose a new category for energy analysis called Retail Goods Movement (RGM) that draws its boundaries around the portion of freight dedicated to retail goods and the portion of driving dedicated to shopping. Historically, the components of RGM have not enjoyed policy priority. However, the net payoff from energy research and policy directed at RGM may now be high enough relative to other options to deserve increased investment. We combine a quantitative decomposition of the dynamics of RGM energy use with a qualitative discussion of what trends could have contributed to them. The RGM sector’s energy use grew from 1.3 EJ (2.8% U.S.) in 1969 to 7.0 EJ (6.6% U.S.) in 2009. The major drivers were increases in population, freight tonnage (before 1990), distance freighted per tonne and driven per shopping trip (after 1990), and weekly shopping trips per household (before 1995). RGM energy intensity increased per capita (180%), per constant dollar GDP (60%), and per retail expenditure (140%). Finally, we describe policy recommendations that could become the basis of a sound RGM resource plan

Be prepared for the unexpected: The gap between (im)mobility intentions and subsequent behaviour of recent higher education graduates

Research on the relationship between mobility intentions and actual mobility behaviour is scarce. This study analyses the factors explaining the gap between (im)mobility intentions and behaviour of recent higher education graduates in the Euregio Meuse‐Rhine, a cross‐border region spanning the Netherlands, Belgium, and Germany. The analysis is based on mixed methods, including survey data collected in 2015 and 2017 as well as semistructured interviews to find out more about respondents' personal mobility trajectories and the extent to which their behaviour reflects their actual (im)mobility preferences. The findings indicate that location‐specific capital impacts the probability to realise one's (im)mobility intention, as do other forms of capital, such as previous mobility experience and an internship during the study. Furthermore, personality traits and unexpected events, such as a change in relationship status, influence if respondents realise their initial (im)mobility intention

Percutaneous transAXillary access for endovascular aortic procedures in the multicenter international PAXA registry

Background: The aim of the study was to demonstrate the safety and effectiveness of a suture-mediated vascular closure device to perform hemostasis after an axillary artery access during endovascular procedures on the aortic valve, the aorta and its side branches. Methods: A physician-initiated, international, multicenter, retrospective registry was designed to evaluate the success rate (VARC-2 reporting standards) of percutaneous transaxillary access closure with a suture-mediated closure device. Secondary end points were minor access vascular complications, transient peripheral nerve injury, stroke, and influence on periprocedural outcomes of puncture technique. Results: Three hundred thirty-one patients (median age, 76 years; 69.2% males) in 11 centers received a percutaneous transaxillary access during endovascular cardiac (n = 166) or vascular (n = 165) procedures. The closure success rate was 84.6%, with 5 open conversions (1.5%), 45 adjunctive endovascular procedures (13.6%), and 1 nerve injury (0.3%). Secondary closure success was obtained in 325 patients (98%) after 7 bare stenting, 37 covered stenting, and 1 thrombin injection. Introducer sheaths 16F or larger (odds ratio, 3.70; 95% confidence interval, 1.22-11.42) and balloon-assisted hemostasis (odds ratio, 4.45; 95% confidence interval, 1.27-15.68) were associated with closure failure. A threshold of five percutaneous axillary accesses was associated with decreased rates of open conversion, but not with increased primary closure success. Primary closure success was 90.3% in the 175 patients with sheaths smaller than 16F, performed after the first 5 procedures in each center. Temporary nerve injury and stroke were observed in 2% and 4% of patients, respectively. Conclusions: Percutaneous transaxillary aortic procedures, in selected patients, can be performed with low rates of open conversion. The need for additional endovascular bailout procedures is not negligible when introducers sheaths 16F or larger are required
