Methods

The hydrolysis of triglycerides in triglyceride-rich lipoproteins by LPL is critical for the delivery of triglyceride-derived fatty acids to tissues, including heart, skeletal muscle, and adipose tissues. Physiologically active LPL is normally bound to the endothelial cell protein glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1 (GPIHBP1), which transports LPL across endothelial cells, anchors LPL to the vascular wall, and stabilizes LPL activity. Disruption of LPL-GPIHBP1 binding significantly alters triglyceride metabolism and lipid partitioning. In this study, we modified the NanoLuc® Binary Technology split-luciferase system to develop a novel assay that monitors the binding of LPL to GPIHBP1 on endothelial cells in real time. We validated the specificity and sensitivity of the assay using endothelial lipase and a mutant version of LPL and found that this assay reliably and specifically detected the interaction between LPL and GPIHBP1. We then interrogated various endogenous and exogenous inhibitors of LPL-mediated lipolysis for their ability to disrupt the binding of LPL to GPIHBP1. We found that angiopoietin-like (ANGPTL)4 and ANGPTL3-ANGPTL8 complexes disrupted the interactions of LPL and GPIHBP1, whereas the exogenous LPL blockers we tested (tyloxapol, poloxamer-407, and tetrahydrolipstatin) did not. We also found that chylomicrons could dissociate LPL from GPIHBP1 and found evidence that this dissociation was mediated in part by the fatty acids produced by lipolysis. These results demonstrate the ability of this assay to monitor LPL-GPIHBP1 binding and to probe how various agents influence this important complex.

Although long one of the world's top migrant destinations, only in the recent past has Germany come to acknowledge and adjust to its role as a country of immigration. Its welcoming approach—a relatively new development—has been put to the test amid massive humanitarian inflows beginning in 2015. This country profile examines Germany's history on immigration and highlights current and emerging debates.

The Netherlands has witnessed a rise in far-right populism, challenging its reputation as a humanitarian haven. Yet, public fears equating immigration with a rise in religious extremism do not necessarily reflect the facts. This profile explores historical and contemporary migration in a country where population growth relies largely on immigration, and analyzes to what extent policymaking has been shaped by rising populism.

The eligibility criteria for special education services is black and white. (I'm not talking about the color of skin.) Either the student fits the criteria or does not fit the criteria. The committee comes together with all the test data and then reviews the criteria for each disability. Either the student is eligible or not. They meet the criteria or they do not meet the criteria. Sounds easy, right? The kids who obviously fit the criteria easily qualify for special education services. The kids who clearly do not fit criteria for special education do not qualify for special education services. It should just be that easy. Sometimes it is.

I've been in the field long enough to see that eligibility is not always this magical process that determines special education from regular education. Sometimes eligibility decisions are a nightmare. What about all the gray kids that aren't clearly black or white?! For some kids, determining if they meet the criteria is tough. The black and white criteria makes it difficult to know what to do for the gray kids. The most difficult eligibility meetings are the ones where some members feel the student meets criteria and other members do not. These can lead to heated discussions. There are sometimes different ways to look at data and opinions of how to look at it may vary. Remember that the real issue the student who is cared about by school staff and especially parents which makes the decision emotional. It can be hard to be objective at times. It is not uncommon to hear "but they need it," even when the data does not support it.

There are kids who qualify for special education services at one point, then are found ineligible at another time. Sometimes this happens because the student has made improvements and no longer requires special education services to be successful. Other times this happens because criteria has changed, the criteria is slightly different in a new different school system, or because test data is slightly different after a few years. In my opinion, this is when the system and criteria fails. I'd like to see ways to address the students who at one time fit the criteria, no longer fit criteria, but still require services.

Why is the criteria so rigid? The main reason is because special education is funded by the government and they keep a tight reign on eligibility criteria. School staff is pressured by the administration, who is pressured by the State, who is pressured by the Federal government. There is a call for identification to be accurate to ensure that funds are properly spent. The only way the government can determine if the funds are being used appropriately is to enforce that schools are using clear criteria guidelines for identification.

All that being said, I believe in the process (for the most part). However, it's created by humans meaning there will be errors. If I had a say, I'd make some changes. I do believe there needs to be criteria. No matter who sets the criteria there will always be those gray kids that are just right on the border of eligible or not eligible. The worst mistake that can be made in my opinion is telling a family that the child has a disability when in fact the child does not. The child grows up with the belief that he or she has a disabling condition, when that could have been prevented. Disability identification can be life changing for a person. That is why I believe we need criteria. A strong opinion by a teacher or parent that "she needs it" is not enough data for me to look a child and say they are struggling because of a disability.

Looking back after one year in office, it is striking how just closely the Trump administration’s actions on immigration have hewed to priorities Donald Trump outlined in an uncommonly detailed policy speech in August 2016. This report revisits those pledges to assess where the administration has made the most and least headway, and what its policy agenda ahead might look like.

The U.S. immigration system is in desperate need of an overhaul. What has been missing is an alternate vision for a path forward that treats immigration as a strategic resource while also accounting for heightened security and rule-of-law imperatives, which together can further U.S. interests, values, and democratic principles as a society. This concept note outlines a new MPI initiative, Rethinking U.S. Immigration Policy, that seeks to fill this gap.

In 2017 the Department of the Prime Minister and Cabinet and Australian Defence Force (Australian Army) undertook a joint review of the Army Aboriginal Community Assistance Programme (AACAP) to assess its efficiency and effectiveness. The review found AACAP is a highly regarded and effective means of achieving positive environmental and primary health outcomes for Aboriginal and Torres Strait Islander communities while providing valuable training outcomes for Army. AACAP's objectives align with the Council of Australian Governments (COAG) 'Closing the Gap' targets in Indigenous disadvantage and with the Australian Government's Indigenous Advancement Strategy (IAS). The report identified areas for potential improvement, recommending greater support for the sustainability of infrastructure and project investment, enhanced employment and training opportunities and strengthening of project governance.

Abstract:
We consider a new nonparametric rule of classification, inspired from the classical moving window rule, that allows for the classification of spatially dependent functional data containing some completely missing curves. We investigate the consistency of this classifier under mild conditions. The practical use of the classifier will be illustrated through simulation studies.

Abstract:
A prompt public health response to a new epidemic relies on the ability to monitor and predict its evolution in real time as data accumulate. The 2009 A/H1N1 outbreak in the UK revealed pandemic data as noisy, contaminated, potentially biased and originating from multiple sources. This seriously challenges the capacity for real-time monitoring. Here, we assess the feasibility of real-time inference based on such data by constructing an analytic tool combining an age-stratified SEIR transmission model with various observation models describing the data generation mechanisms. As batches of data become available, a sequential Monte Carlo (SMC) algorithm is developed to synthesise multiple imperfect data streams, iterate epidemic inferences and assess model adequacy amidst a rapidly evolving epidemic environment, substantially reducing computation time in comparison to standard MCMC, to ensure timely delivery of real-time epidemic assessments. In application to simulated data designed to mimic the 2009 A/H1N1 epidemic, SMC is shown to have additional benefits in terms of assessing predictive performance and coping with parameter nonidentifiability.

Abstract:
We propose a generic spatiotemporal event forecasting method which we developed for the National Institute of Justice’s (NIJ) Real-Time Crime Forecasting Challenge (National Institute of Justice (2017)). Our method is a spatiotemporal forecasting model combining scalable randomized Reproducing Kernel Hilbert Space (RKHS) methods for approximating Gaussian processes with autoregressive smoothing kernels in a regularized supervised learning framework. While the smoothing kernels capture the two main approaches in current use in the field of crime forecasting, kernel density estimation (KDE) and self-exciting point process (SEPP) models, the RKHS component of the model can be understood as an approximation to the popular log-Gaussian Cox Process model. For inference, we discretize the spatiotemporal point pattern and learn a log-intensity function using the Poisson likelihood and highly efficient gradient-based optimization methods. Model hyperparameters including quality of RKHS approximation, spatial and temporal kernel lengthscales, number of autoregressive lags and bandwidths for smoothing kernels as well as cell shape, size and rotation, were learned using cross validation. Resulting predictions significantly exceeded baseline KDE estimates and SEPP models for sparse events.

Abstract:
Spatial confounding between the spatial random effects and fixed effects covariates has been recently discovered and showed that it may bring misleading interpretation to the model results. Techniques to alleviate this problem are based on decomposing the spatial random effect and fitting a restricted spatial regression. In this paper, we propose a different approach: a transformation of the geographic space to ensure that the unobserved spatial random effect added to the regression is orthogonal to the fixed effects covariates. Our approach, named SPOCK, has the additional benefit of providing a fast and simple computational method to estimate the parameters. Also, it does not constrain the distribution class assumed for the spatial error term. A simulation study and real data analyses are presented to better understand the advantages of the new method in comparison with the existing ones.
