A new bijection relating qq-Eulerian polynomials

On the set of permutations of a finite set, we construct a bijection which maps the 3-vector of statistics $(maj-exc,des,exc)$ to a 3-vector $(maj\_2,\widetilde{des\_2},inv\_2)$ associated with the $q$-Eulerian polynomials introduced by Shareshian and Wachs in \textit{Chromatic quasisymmetric functions, arXiv:1405.4269(2014).

A bijection between the irreducible k-shapes and the surjective pistols of height k-1

This paper constructs a bijection between irreducible $k$-shapes and surjective pistols of height $k-1$, which carries the "free $k$-sites" to the fixed points of surjective pistols. The bijection confirms a conjecture of Hivert and Mallet (FPSAC 2011) that the number of irreducible $k$-shape is counted by the Genocchi number $G_{2k}$

When Is Fear for One\u27s Life Race-Gendered? An Intersectional Analysis of the Bureau of Immigration Appeals\u27s \u3ci\u3eIn re A-R-C-G-\u3c/i\u3e Decision

In August 2014, the U.S. Board of Immigration Appeals (BIA) handed down a breakthrough decision, In re A-R-C-G-, permitting courts to consider domestic violence as a gendered form of persecution in a home country and thus grounds for asylum in the United States. Along with two other 2014 decisions, In re W-G-R- and In re M-E-V-G-, this case represented a marked shift from prior BIA decisions, which for fifteen years had interpreted sections 208(a) and 241(b)(3) of the Immigration and Naturalization Act more narrowly, thus excluding claims of home country abuse as reasonable grounds to grant asylum. Specifically, in A-R-C-G-, the BIA found that Guatemalan women fleeing domestic violence can be considered a “particular social group” (PSG). Its decision has been celebrated as a step forward in resolving contradictory and arbitrary outcomes that persisted in a vacuum of jurisprudential norms about the issue

Identifying Privacy Policy in Service Terms Using Natural Language Processing

Ever since technology (tech) companies realized that people\u27s usage data from their activities on mobile applications to the internet could be sold to advertisers for a profit, it began the Big Data era where tech companies collect as much data as possible from users. One of the benefits of this new era is the creation of new types of jobs such as data scientists, Big Data engineers, etc. However, this new era has also raised one of the hottest topics, which is data privacy. A myriad number of complaints have been raised on data privacy, such as how much access most mobile applications require to function correctly, from having access to a user\u27s contact list to media files. Furthermore, the level of tracking has reached new heights, from tracking mobile phone location, activities on search engines, to phone battery life percentage. However much data is collected, it is within the tech companies\u27 right to collect the data because they provide a privacy policy that informs the user on the type of data they collect, how they use that data, and how they share that data. In addition, we find that all privacy policies used in this research state that by using their mobile application, the user agrees to their terms and conditions. Most alarmingly, research done on privacy policies has found that only 9% of mobile app users read legal terms and conditions [2] because they are too long, which is a worryingly low number. Therefore, in this thesis, we present two summarization programs that take in privacy policy text as input and produce a shorter summarized version of the privacy policy. The results from the two summarization programs show that both implementations achieve an average of at least 50%, 90%, and 85% on the same sentence, clear sentence, and summary score grading metrics, respectively

Market Access, Export Subsidies, Domestic Support and the WTO Negociations: a Review and Synthesis

The aim of this review is to provide a preliminary assessment of the implementation of the Uruguay Round Agreement on Agriculture (URAA) in order to highlight the directions that might take the next stage of reform. A particular focus is made on the Quads countries. Our findings are that, in spite of the URAA arrangements, tariffs on agricultural products are still three times higher on average than on manufactured products. The tariffication process has often led to prohibitive duties and to an increase in tariff dispersion. Tariff rate quotas (TRQs) have not always been filled and market access has shown only limited improvement. Export subsidies still exist and domestic farm policies have often experienced only minor changes to match the Agreement requirements. These points, which have been identified as live issues for the next Round of Negotiations, are then debated in the rest of the document. We discuss in particular the modalities of ameliorating market access, with the definition of a more effective tariff cut and the improvement of TRQs' administration and efficiency. As far as exports are concerned, we tackle the issue of effectiveness of a new reduction of export subsidies, the status of export credit and of export restrictions. The more general question of state involvement in agricultural trade is also discussed. Finally, we pose the question of a deepening of the reduction of support to agriculture, with an elimination of the "blue box" and a new definition of the "green box" content.support to agriculture., export subsidies, market access, agriculture, trade negotiations, WTO
