Mercantilism and marketization? Analysis of China's reserve accumulation and changes in exchange rate regime using the monetary policy trilemma
No full text2019-08-23This paper will examine China's foreign exchange reserves accumulation alongside changes to its exchange rate regime using the dual lens of mercantilism and marketization. It argues that a look at the mercantilistic accumulation of foreign exchange reserves alone is insufficient, but must be analyzed alongside changes to the exchange rate regime in the direction of more market-oriented reforms. The analysis shows that China is balancing the tradeoffs of the monetary policy trilemma, relinquishing control of each while maintaining absolute control over none
WISER women’s program: well-being innovation with support and education for resilience—a homelessness prevention intervention
No full text2019-09-11The numbers of older adults losing their homes have risen in recent years, leading to an increasing inflow to the streets even as public efforts have been directed to housing those already there. WISER, a new intervention addressing the Social Work Grand Challenge of Homelessness, focuses on preventing the most vulnerable low-income women from becoming homeless in their later years, especially African American women. The program consists of a 6 month structured support group intervention intended to include trauma-informed principles, cultural perspectives, and support group concepts. These are combined with a financial empowerment approach that provides access to key resources and builds self-efficacy to achieve improved financial stability. WISER can be used to assist women who are unstable financially and also be paired with emergency resources for those at imminent risk of housing loss

Incrementality for visual reference resolution in spoken dialogue systems
No full text2019-09-19There are several challenges involved in developing naturally and efficiently conversing Spoken Dialogue Systems (SDS). Fluid turn-taking is one such challenge. In traditional SDS the system has to wait until the user has finished speaking before starting to process the user's input in order to respond to it. Incremental dialogue processing is an important feature in SDS that can make them more efficient and natural compared to their non-incremental counterparts. Incrementality in SDS means that the processing of the user utterances (word-by-word) starts before the input is completely available and the system generates output increments as soon as possible, which in turn results in natural and efficient human-system interaction. ❧ In this thesis, I first present models for incremental dialogue policy development and show that the incremental dialogue policy helps SDS perform better than their non-incremental counterparts and about as well as humans. Then I present an incremental dialogue policy developed using reinforcement learning. The work then provides models for incremental utterance segmentation and labeling in multiple domains. The work also applies transfer learning towards the development of an incremental dialogue policy. I show that an effective policy can be learned with fewer data samples using a transfer learning approach. Collecting data for the development of an SDS is an important step. In this work, I also develop a web-based crowd-sourcing framework for collecting spoken interaction data
Exploiting diversity with online learning in the Internet of things
No full text2019-09-23Over the past 15 years, research in wireless sensor networks has progressed dramatically and several wireless technologies can now be found in devices that are present in our daily lives. It is estimated that more than 11 billion devices are already connected to the Internet of Things, some of them through wireless sensor networks comprising constrained devices that run on batteries and have limited capabilities. The next breakthrough will be the introduction of these technologies in industrial environments for the interconnection of machinery and automation of processes. This new scenario is also known as the Industrial Internet of Things (IIoT). The IIoT will be essential for the success of the Industry 4.0, which is the vision where industrial processes will be able to leverage cyber-physical systems to allow machines and humans to interact and create customizable and dynamic ""smart factories"". ❧ There have been significant advances in the area of IoT and many of the classic problems in this field have already been solved. However, the new requirements of the IIoT have brought up new problems that have yet to be addressed. Such networks will need to meet more stringent requirements for throughput, reliability, delay and power consumption. Despite advances in hardware and new standards, there are still a large number of sensors already operating that must be reused in the future IIoT. This means that the new protocols and standards for the IIoT may still be able to use legacy hardware and will have to improve the network performance by making use of more advanced algorithms in the network stack. The most widely used IoT radio standard, IEEE 802.15.4, has been enhanced to provide a scheduling protocol for more robust operations and better use of radio resources. The improvements made for the IEEE 802.15.4 standard are part of the Time-Slotted Channel Hopping (TSCH) protocol, which will be the main target of the proposals in this dissertation. ❧ We set out some different ways to explore diversity in the wireless networks, which are aimed at improving the performance of the IoT protocols and meeting the requirements of IIoT while maintaining the compatibility with legacy hardware and protocols such as TSCH. The strategies improve the use of radio resources by exploiting time, frequency and spatial diversity. This dissertation initially examines the variations in the quality of the wireless links in several testbeds, concerning the three domains previously mentioned, i.e., time, frequency and space. Following this, we reveal three solutions: FBR-TSCH, MABO-TSCH and TAMU-RPL. The Flooding-Based Reliable TSCH protocol (FBR-TSCH) is a protocol for event-triggered applications that is optimized for the collection of non-deterministic signals sent by a sensor to a sink node in a dynamic environment with high levels of external interference. The Multi-hop and Blacklist-based Optimized TSCH (MABO-TSCH) is a protocol for improving frequency hopping algorithm. It employs a distributed blacklist that is optimized for multi-hop networks in environments with high levels of external interference and multi-path fading. Finally, the Thompson Sampling-based Multi-channel RPL (TAMU-RPL) is a protocol to optimize the reactiveness of routing algorithms. It uses a Thompson Sampling heuristic to make a dynamic parent selection and quickly change the routing tree in networks with high levels of external interference. Even though the solutions proposed are focused on specific technologies and protocols, such as TSCH and RPL, the algorithms introduced are generic enough to be used in other scenarios where online learning is required to optimize the distributed decision-making and improve the performance of networks by exploiting different kinds of diversities. The results show that even with constrained hardware, the networks can cope with unreliable links caused by high levels of external interference and multi-path fading, and achieve a performance that meets the requirements of some of the applications in the IIoT

"17. Los Angeles Mission, Los Angeles.", stereoscopic photograph, circa 1872
No full text"17. Los Angeles Mission, Los Angeles." Henry T. Payne, stereoscopic photograph, circa 1872. The view is from the area in or near the Pico House hotel on the east side of Main Street looking northwest toward the Plaza Church, of which the front entrance, with a projecting fenced area, and the adjacent tower topped by a gazebo are of note. At left is a high wall bordered by trees behind which was the original cemetery. In the distance at the far right, however, at the base of Elysian Hills is the fenced Calvary Cemetery, which replaced the Plaza Church burying ground in 1844. At the far left is another fenced area at the base of the hills which is the Jewish Cemetery, established about 1854. To the right behind the church are some one-story adobe structures in the Sonoratown area. The caption is on a paper label pasted down at the right, while Payne's name and location and the phrase "SOUTHERN CALIFORNIA" are on the margins. it is possible Payne republished earlier images of William M. Godfrey because of the similarity to images of the latter, such as .1 of this accession. With some soiling, edge rubbing and a few light stains, the overall condition is good
