    The Effects of Cultural Diplomacy on Public Perception in Asia

    Many states use their cultures to promote a positive image of themselves abroad. Some scholars argue that this can provide states with international benefits. However, other scholars point to cases where a foreign state’s cultural influence has led to nationalist backlashes and negative public reactions. In this paper, I examine how two common types of cultural diplomacy programs can influence how states are perceived abroad. I first look at the promotion of pop culture products, such as books, movies, and music. Using survey data from 12 Asian countries, I find that an increase in cultural product imports from Japan, South Korea, and China has a negative effect on how respondents view the cultural exporter. I then look at cultural centers, using China’s Confucius Institute program. I find that the presence of Confucius Institutes is associated with an increase in positive opinions of China. These results provide some empirical evidence that cultural products can be detrimental to a state’s international image. As a result, states interested in the international benefits of cultural diplomacy should be wary of promoting cultural products abroad. Additionally, while previous studies do not distinguish between the effects that different types of cultural diplomacy programs can have, these findings demonstrate that different cultural diplomacy strategies can have widely different effects on foreign public opinion

    Evaluating Multiple Arthropod Taxa as Indicators of Invertebrate Diversity in Old Fields

    Biodiversity, often quantified by species richness, is commonly used to evaluate and monitor the health of ecosystems and as a tool for conservation planning. The use of one or more focal taxa as surrogates or indicators of larger taxonomic diversity can greatly expedite the process of biodiversity measurement. This is especially true when studying diverse and abundant invertebrate fauna. Before indicator taxa are employed, however, research into their suitability as indicators of greater taxonomic diversity in an area is needed. We sampled invertebrate diversity in old fields in southern Michigan using pitfall trapping and morphospecies designations after identification to order or family. Correlation analysis was used to assess species richness relationships between focal arthropod taxa and general invertebrate diversity. Relationships were assessed at two fine spatial scales: within sampling patches, and locally across four sampling patches. Cumulative richness of all assessed taxa increased proportionately with cumulative invertebrate richness as sampling intensity increased within patches. At the among-patch scale, we tentatively identified Hemiptera and Coleoptera as effective indicator taxa of greater invertebrate richness. Although Hymenoptera, Araneae and Diptera exhibited high species richness, their total richness within patches was not associated with overall invertebrate richness among patches. Increased sampling throughout the active season and across a greater number of habitat patches should be conducted before adopting Hemiptera and Coleoptera as definitive indicators of general invertebrate richness in the Great Lakes region. Multiple sampling techniques, in addition to pitfall trapping, should also be added to overcome capture biases associated with each technique

    Association of Household and Community Characteristics with Adult and Child Food Insecurity among Mexican-Origin Households in Colonias along the Texas-Mexico Border

    <p>Abstract</p> <p>Background</p> <p>Food insecurity is a critical problem in the United States and throughout the world. There is little published data that provides insights regarding the extent and severity of food insecurity among the hard-to-reach Mexican-origin families who reside in the growing <it>colonias </it>along the Texas border with Mexico. Considering that culture, economics, and elements of the environment may increase the risk for food insecurity and adverse health outcomes, the purpose of this study was to examine the relation between household and community characteristics and food insecurity.</p> <p>Methods</p> <p>The study used data from the 2009 <it>Colonia </it>Household and Community Food Resource Assessment (C-HCFRA). The data included 610 face-to-face interviews conducted in Spanish by <it>promotoras </it>(indigenous community health workers) in forty-four randomly-identified <it>colonias </it>near the towns of Progreso and La Feria in Hidalgo and Cameron counties along the Texas border with Mexico. C-HCFRA included demographic characteristics, health characteristics, food access and mobility, food cost, federal and community food and nutrition assistance programs, perceived quality of the food environment, food security, eating behaviors, and alternative food sources.</p> <p>Results</p> <p>78% of participants experienced food insecurity at the level of household, adult, or child. The most severe - child food insecurity was reported by 49% of all households and 61.8% of households with children. Increasing levels of food insecurity was associated with being born in Mexico, increasing household composition, decreasing household income, and employment. Participation in federal food assistance programs was associated with reduced severity of food insecurity. Greater distance to their food store and perceived quality of the community food environment increased the odds for food insecurity.</p> <p>Conclusions</p> <p>The Mexican-origin population is rapidly expanding; record numbers of individuals and families are experiencing food insecurity; and for those living in rural or underserved areas such as the <it>colonias</it>, the worst forms of food insecurity are an ongoing reality. The rates of households with adult and child food insecurity in this border area are alarming and among the highest reported. Clearly, systematic and sustained action on federal, state, and community levels is needed to reduce household, adult, and child food insecurity that integrates cultural tailoring of interventions and programs to address food and management skills, multi-sector partnerships and networks, expansion of food and nutrition assistance programs, and enhanced research efforts.</p

    Staged Contact Optimization: Combining Contact-Implicit and Multi-Phase Hybrid Trajectory Optimization

    Full text link
    Trajectory optimization problems for legged robots are commonly formulated with fixed contact schedules. These multi-phase Hybrid Trajectory Optimization (HTO) methods result in locally optimal trajectories, but the result depends heavily upon the predefined contact mode sequence. Contact-Implicit Optimization (CIO) offers a potential solution to this issue by allowing the contact mode to be determined throughout the trajectory by the optimization solver. However, CIO suffers from long solve times and convergence issues. This work combines the benefits of these two methods into one algorithm: Staged Contact Optimization (SCO). SCO tightens constraints on contact in stages, eventually fixing them to allow robust and fast convergence to a feasible solution. Results on a planar biped and spatial quadruped demonstrate speed and optimality improvements over CIO and HTO. These properties make SCO well suited for offline trajectory generation or as an effective tool for exploring the dynamic capabilities of a robot

    Hebbian Reverberations in Emotional Memory Micro Circuits

    The study of memory in most behavioral paradigms, including emotional memory paradigms, has focused on the feed forward components that underlie Hebb's first postulate, associative synaptic plasticity. Hebb's second postulate argues that activated ensembles of neurons reverberate in order to provide temporal coordination of different neural signals, and thereby facilitate coincidence detection. Recent evidence from our groups has suggested that the lateral amygdala (LA) contains recurrent microcircuits and that these may reverberate. Additionally this reverberant activity is precisely timed with latencies that would facilitate coincidence detection between cortical and sub cortical afferents to the LA. Thus, recent data at the microcircuit level in the amygdala provide some physiological evidence in support of the second Hebbian postulate

    Within the Unmanned Aircraft Systems (UAS) Traffic Management (UTM) system, the UAS Service Supplier (USS) is a key component. The USS serves several functions. At a high level, those include the following: Bridging communication between UAS Operators and Flight Information Management System (FIMS) Supporting planning of UAS operations Assisting strategic deconfliction of the UTM airspace Providing information support to UAS Operators during operations Helping UAS Operators meet their formal requirements This document provides the minimum set of requirements for a USS. In order to be recognized as a USS within UTM, successful demonstration of satisfying the requirements described herein will be a prerequisite. To ensure various desired qualities (security, fairness, availability, efficiency, maintainability, etc.), this specification relies on references to existing public specifications whenever possible

    Valuation of Closely-Held Stock for Federal Tax Purposes: Approach to an Objective Method

    Get PDF
    The present double-standard approach to the valuation problem discriminates against owners of closely-held stock, that is, corporate shares which have no public market. The disparity of treatment is traceable to the unfortunate fact that, whereas actual sales or bona fide bid and asked prices govern the valuation for federal tax purposes of listed stocks and of unlisted stocks which are dealt in through brokers or have a market, the criteria employed in valuing closely-held stock are predominantly subjective. This makes a paradise for experts but they seldom agree and few, if any, of their assumptions and conclusions are anything more than unverified, and not always wholly disinterested, hunches. As a consequence, disagreement between taxpayer and revenue agent is frequent and the process of resolving disagreement is long and costly and the event uncertain. In short, the whole merry-go-round of valuing closely-held stock is wasteful and unfair. This paper and the study it reports are addressed to the possibility of improving the situation by making a fresh approach to the valuation of closely-held stock
