The early twentieth century brought political, economic, and social changes to Peru. After the devastating losses experienced from the War of the Pacific in the late 1800s, the need to reconstruct and reform Peruvian society lent itself to the economic opportunities modernization presented. This exhibition of postcards from the 1920s show how the past and present converged in Peru at this critical juncture. ; UT Libraries

The author, writer and filmmaker Neil Hollander has been having a successful career for more than three decades. He's been author of several books for kids and more books that serve as a manuals for surviving on open sea. With his latest books Hollander has been advocating for world peace and bringing closer to the public the horrific life of people living under military regime in Burma. He is also active as a public speaker covering these and similar subjects. As a filmmaker Hollander started his career back in 70's when together with Harald Mertes went on a voyage around the Ocean on a sailing boat, Spending three years on this trip he visited many places and learned many things about life on sea. Later he documented these finding in his book, which he also used as a screenplay for his awarded documentary film The Last Sailors: The Final Days of Working Sail. The film is hosted by Orson Welles who in this classic documentary film tells the story of the men who, with their ancient craft, still harness the wind and the sea for their livelihood. The film includes stories from people living all over the world, including countries like Egypt, Bangladesh, Indonesia, Brazil, Costa Rica and other places. Hollander is artist that is best known for his exhibitions hosted in collaboration with some world-recognized museums and art schools. In his career he has worked with the Smithsonian, the Deutsches Museum and the Jim Thompson House in Bangkok. Lately his project are publicly visible at his portfolio at Rhode Island School of Design (RISD). Projects worth mentioning as one of the best in his portfolio include Hollander's Nobel Voices, Neil Hollander Burma A Human Tragedy, Birds of Passage, H for Hunger, to name a few.

Semaphorin 3A (Sema3A) is a cell-secreted protein that participates in the axonal guidance pathways. Sema3A acts as a canonical repulsive axon guidance molecule, inhibiting CNS regenerative axonal growth and propagation. Therefore, interfering with Sema3A signaling is proposed as a therapeutic target for achieving functional recovery after CNS injuries. It has been shown that Sema3A adheres to the proteoglycan component of the extracellular matrix (ECM) and selectively binds to heparin and chondroitin sulfate-E (CS-E) glycosaminoglycans (GAGs). We hypothesize that the biologically relevant interaction between Sema3A and GAGs takes place at Sema3A C-terminal polybasic region (SCT). The aims of this study were to characterize the interaction of the whole Sema3A C-terminal polybasic region (Sema3A 725–771) with GAGs and to investigate the disruption of this interaction by small molecules. Recombinant Sema3A basic domain was produced and we used a combination of biophysical techniques (NMR, SPR, and heparin affinity chromatography) to gain insight into the interaction of the Sema3A C-terminal domain with GAGs. The results demonstrate that SCT is an intrinsically disordered region, which confirms that SCT binds to GAGs and helps to identify the specific residues involved in the interaction. NMR studies, supported by molecular dynamics simulations, show that a new peptoid molecule (CSIC02) may disrupt the interaction between SCT and heparin. Our structural study paves the way toward the design of new molecules targeting these protein–GAG interactions with potential therapeutic applications. ; This work was funded by the European Union Seventh Framework Programme (FP7/2007–2013) under Project VISION, grant No. 304884, the Spanish Ministry of Science and Innovation/Spanish Research Agency (MCI/AEI/FEDER, RTI2018–096182-B-I00) and AGAUR (2017 SGR 208). ; Peer reviewed

This thesis critically analyzes the H-2C temporary worker program (TWP) that was part of the 2006, Senate-approved Comprehensive Immigration Reform Act. Employer opinions and lessons from past U.S. TWPs are presented, resulting in recommendations for changing H-2C's design in order to maximize its potential as a core component of future immigration reform in the United States. The paper finds that small businesses, which comprise the majority of the businesses in the United States, and are among the heaviest users of foreign labor, consider the 2006 H-2C program to be unaffordable. Policy makers must redesign H- 2C to be affordable for small businesses while still offering an effective system for protecting domestic worker interests. The paper concludes that the best means to achieve both program affordability for small businesses and effectual domestic worker protections is likely a user -friendly, electronic program process
