Crapemyrtle bark scale (CMBS; Acanthococcus lagerstroemiae) is an exotic pest species that causes aesthetic and economic damage to crapemyrtles and poses potential threats to other horticultural crops in the United States. Although previous studies reported the infestation of CMBS on several alternative hosts across multiple families in Asia, its potential threats to other documented alternative hosts remain elusive and yet to be confirmed. In this study, feeding preference studies of CMBS were conducted on forty-nine plant species and cultivars in 2016 and 2019, in order to gain insight into the expansion of CMBS distribution in the United States, as well as other regions of the world. The infestations of CMBS were confirmed on apple (Malus domestica), Chaenomeles speciosa, Disopyros rhombifolia, Heimia salicifolia, Lagerstroemia ‘Spiced Plum’, M. angustifolia, and twelve out of thirty-five pomegranate cultivars. However, the levels of CMBS infestation on these test plant hosts in this study is very low compared to Lagerstroemia, and may not cause significant damage. No sign of CMBS infestation was observed on Rubus ‘Arapaho’, R. ‘Navaho’, R. idaeus ‘Dorman Red’, R. fruticosus, B. microphylla var. koreana × B. sempervirens, B. harlandii, or D. virginiana.

This article details how a newly arrived Turkish refugee student navigates schooling in the United States. It highlights the trauma a purged Turkish families experience in their home country and their challenges as newcomers unfamiliar with their new country’s dominant culture, language, and education system. The case narrative provides insight into how children of Turkish political refugees are often overlooked in the context of U.S. schools, where teachers lack adequate training and supports. By illuminating one refugee family’s experiences in U.S. schools, the case calls for leaders to develop holistic supports and teacher education focused on the needs of refugee students.

AbstractThe idea to create and stage a play called »Heimat im Koffer« – »A home in the suitcase« – emerged, I presume, in Vienna shortly before Austria became part of National Socialist Germany in 1938: the plot involved the magical translocation of a typical Viennese coffeehouse, with all its inhabitants and with the songs they sang, to New York; their confrontation with American everyday life and musical traditions would create the humorous situations the authors hoped for. Since 1933, Robert Gilbert (Robert David Winterfeld, 1899–1978), the son of a famous Jewish musician and himself a most successful writer of popular music for film and operetta in Weimar Germany, found himself in exile in Vienna where he cooperated with the journalist Rudolf Weys (1898–1978) and the piano artist Hermann Leopoldi (1888–1959). Whereas Gilbert and Leopoldi emigrated to the United States and became a part of the German-Jewish and Austrian-Jewish emigré community of New York – summarizing their experience in a song about the difficulty to acquire the new language, »Da wär’s halt gut, wenn man Englisch könnt« (1943) – Weys survived the war years in Vienna. After 1945, Gilbert and Weys renewed their contact and discussed – in letters kept today within the collection of the Viennese Rathausbibliothek – the possibility to finally put »Heimat im Koffer« on stage. The experiences of exile, it turned out, proved to be too strong, and maybe too serious, for the harmless play to be realized, but the letters do give a fascinating insight into everyday-life during emigration, including the need to learn English properly, and into the impossibility to reconnect to the former life and art.

Estimates of climate change damage are central to the design of climate policies. Here, we develop a flexible architecture for computing damages that integrates climate science, econometric analyses, and process models. We use this approach to construct spatially explicit, probabilistic, and empirically derived estimates of economic damage in the United States from climate change. The combined value of market and nonmarket damage across analyzed sectors—agriculture, crime, coastal storms, energy, human mortality, and labor—increases quadratically in global mean temperature, costing roughly 1.2% of gross domestic product per +1°C on average. Importantly, risk is distributed unequally across locations, generating a large transfer of value northward and westward that increases economic inequality. By the late 21st century, the poorest third of counties are projected to experience damages between 2 and 20% of county income (90% chance) under business-as-usual emissions (Representative Concentration Pathway 8.5).

This qualitative key informant study examined the emerging role of the doctor of nursing practice (DNP) degree to fill a gap in health care in the United States. Although the DNP degree was proposed to bring added value to the health care system, it is new with little research to confirm the assumption. This research addressed this need by phone interviews of 12 practicing DNPs in the United States. Questions asked of the participants focused on differences in role/practice as a DNP and challenges faced. The interviews were audiotaped, transcribed, and responses coded for themes. Five broad categories with relational themes emerged from the data of DNPs perceptions of their practices. The categories included educational preparation, practice settings, role acceptance, leadership, and challenges. The results of this study provide insight into the perceptions of practicing DNPs experiencing adjustment to practice as a DNP. These perceptions aid other DNPs and educators in preparing advance practice nurses for the future.

This paper examines the history of clinical librarianship in Canada from 1970 to 2013 as seen through the lens of practitioner narratives and published literature. While no reviews of clinical librarianship in Canada were found in the literature search, there were many project descriptions in articles and published reports that have provided insight into the field during its formative period in Canada from the 1970s. In addition to tracing narrative histories from 1970 to 2013, the author has continued to wonder why these important stories have never properly been told. Was it because the scope of clinical librarianship, its expected and embodied professional duties, was not regulated (as it is in the United States and United Kingdom)? Is it because the American Library Association accredited library schools in Canada do not offer appropriate curricula and professional training? It seems clear that some librarians in Canada were pioneers in the way that Gertrude Lamb was in the United States, but they did not call themselves clinical librarians. Consequently, they opted for more generic job titles such as medical librarian and health librarian. Whatever the reasons for this, it is within this framework that the author begins an exploration of clinical librarianship in Canada. The paper's aim is to provide a view into clinical librarianship in Canada back to the 1970s to ensure the story is properly told.

Drosophila suzukii, or spotted-wing drosophila, is now an established pest in many parts of the world, causing significant damage to numerous fruit crop industries. Native to East Asia, D. suzukii infestations started in the United States a decade ago, occupying a wide range of climates. To better understand invasion ecology of this pest, knowledge of past migration events, population structure, and genetic diversity is needed. To improve on previous studies examining genetic structure of D. suzukii, we sequenced whole genomes of 237 individual flies collected across the continental U.S., as well as several representative sites in Europe, Brazil, and Asia, to identify hundreds of thousands of genetic markers for analysis. We analyzed these markers to detect population structure, to reconstruct migration events, and to estimate genetic diversity and differentiation within and among the continents. We observed strong population structure between West and East Coast populations in the U.S., but no evidence of any population structure North to South, suggesting there is no broad-scale adaptations occurring in response to the large differences in regional weather conditions. We also find evidence of repeated migration events from Asia into North America have provided increased levels of genetic diversity, which does not appear to be the case for Brazil or Europe. This large genomic dataset will spur future research into genomic adaptations underlying D. suzukii pest activity and development of novel control methods for this agricultural pest.

ABSTRACT Throughout the bulk of the Reformed Tradition’s history within both Europe and the United States, most scholars have dismissed pastor and theologian Moïse Amyraut as a seventeenth century French heretic whose actions and theology led to the demise of the Huguenots in France. However, upon further introspection into Amyraut’s claims as being closer to Calvin (soteriologically) than his Genevan successors, one finds uncanny parallels in the scriptural commentaries and biblical insight into the expiation of Christ between Calvin and Amyraut. By comparing key scriptural passages concerning the atonement, this article demonstrates that Reformed theologian Moïse Amyraut in fact propagated a universal atonement theory which parallels Calvin’s, both men ascribing to biblical faithfulness, a (humanistic) theological method, and similar hermeneutic. As such, both Calvin and Amyraut scripturally contend that God desires and provided the means for the salvation of the whole world. Further, the article demonstrates that Calvin’s successor, Theodore de Beza, could not in fact make the same claims as Amyraut, this article demonstrating that Beza went beyond Calvin’s scriptural approach to Christ’s expiation. Therefore, this article supports a more centrist approach from within and outside the Reformed tradition by demonstrating that Calvin and Amyraut concentrically held to God’s gracious provision in Christ for the saving of the whole world, for those who would believe in Christ for salvation.

The two versions of the autobiography that Nicholas Said published offer insight into 19th-century conditions in five continents as well as insight into life as a child, slave, manservant, and teacher. As a child in the 1830s, Said was enslaved in Borno, marched across the Sahara Desert, and passed from hand to hand in North Africa and the Middle East. After serving as a slave in various societies, Said was freed by a Russian aristocrat in the late 1850s after accompanying the aristocrat in question to various parts of Europe. In the 1850s, Said also traveled as a manservant for a European traveler to South and North America. Ultimately he settled in the United States, where he authored two versions of his autobiography, served as a teacher and soldier, got married, and disappeared from sight. This article compares the two versions of the autobiography that Said published, provides an overview of Said’s life, charts the development of scholarly works on Said, and draws attention to the primary sources related to the study of Said and his autobiography.

Abstract This article combines the study of Taiwan’s New Southbound Policy with a case study of Taiwan–Myanmar relations from a perspective of political relations, economic cooperation, and Taiwan’s (un)recognisability in Myanmar—i.e. Taiwan’s soft power in Myanmar. The first part of the paper introduces the policy and compares it with the previous ones, and sheds light on Taiwan’s motivation to engage with Myanmar. It considers the ongoing trade war between the United States and China, due to which investment relocation from China is expected to sharply increase. The second part of the paper provides an insight into the relationship between Taiwan and Myanmar after Myanmar’s state-led political transformation from military rule and economic liberalisation since approximately 2010. It explains the main aspects and determinants of the relationship between two countries that share a neighbouring potential hegemon which they both wish to balance against.

This paper examines historic federal immigration policies that demonstrate how the United States has rendered entire groups of people living inside and outside of its territory as outsiders. Collective representations like the Statue of Liberty suggest that the U.S. is a nation that welcomes all immigrants, when in reality, the U.S. has historically functioned as a “gatekeeper” that excludes specific groups of people at different times. The concurrent existence of disparate beliefs within a society’s collective consciousness influences the public’s views toward citizenship and results in policy outcomes that contrast sharply from the ideal values that many collective representations signify. As restrictive immigration controls are refined, insight into how immigrant exclusion via federal policy has evolved is necessary to minimize future legislative consequences that have the potential to ostracize current and future Americans.
