The invasive Mexican rice borer, Eoreuma loftini (Dyar), expanded its range from Mexico to South Texas in the early 1980s. By 2008 the pest had moved into sugarcane- and rice-growing areas of East Texas and Louisiana, and by 2012 it was reported on noncrop host plants in Florida. Efforts to suppress E. loftini in United States sugarcane with chemicals and biological control agents were unsuccessful, so both tactics were discontinued, and E. loftini infestation of sugarcane has continued unchecked. During the last 15 years, however, research has focused on the pest’s ecology, improved insecticides and scouting methods, the identification of sugarcane resistance mechanisms, and new cultural tactics. A surveillance technique was developed that indicates when larvae are most vulnerable to insecticide sprays. Currently, registered insecticides for E. loftini control are not widely applied, although some show promise, including an insect growth regulator. A number of potentially useful cultural practices are available, including plowing under fallow stubble, judicious use of fertilizer, adequate irrigation, avoiding proximity to E. loftini-susceptible maize cultivars, and enhancement of natural enemy populations. Demonstrated and potentially useful sugarcane resistance mechanisms involve physiochemical attributes, physical characteristics, and transgenic cultivars.

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]

AbstractAccording to the mainstream narrative about race, all groups have the same innate dispositions and potential, and all disparities—at least those favoring whites—are due to past or present racism. Some people who reject this narrative gravitate toward an alternative, anti-Jewish narrative, which sees recent history in terms of a Jewish/gentile conflict. The most sophisticated promoter of the anti-Jewish narrative is the evolutionary psychologist Kevin MacDonald. MacDonald argues that Jews have a suite of genetic adaptations—including high intelligence and ethnocentrism—and cultural practices that lead them to undermine gentile society to advance their own evolutionary interests. He says that Jewish-designed intellectual movements have weakened gentile identity and culture while preserving Jewish identity and separatism. Cofnas recently argued that MacDonald’s theory is based on “systematically misrepresented sources and cherry-picked facts.” However, Cofnas gave short shrift to at least three key claims: (a) Jews are highly ethnocentric, (b) liberal Jews hypocritically advocate liberal multiculturalism for gentiles/gentile countries but racial purity and separatism for Jews/Israel, and (c) Jews are responsible for liberalism and mass immigration to the United States. The present paper examines these claims and concludes that MacDonald’s views are not supported.

Global Internet use is circumscribed by local political and economic institutions and inscribed in distinctive cultural practices. This article presents a comparative study of Internet use in China, the United States, and five European countries. The empirical findings suggest a convergence of cultures, specifically regarding interpersonal communication, alongside characteristic national and sociodemographic configurations of different prototypes of human communication. Drawing on the classic understanding of communication as a cultural process producing, maintaining, repairing, and transforming a shared reality, we interpret such configurations as cultures of communication, which can be seen to differ, overlap, and converge across regions in distinctive ways. Looking beyond traditional media systems, we call for further cross-cultural research on the Internet as a generic communication system joining global and local forms of interaction.

The study reports on a telecollaboration exchange between two teacher education classes in the United States and Turkey. In synchronous and asynchronous conversations, preservice teachers (PTs) engaged in social justice issues and made discourse choices that captured culture(s) and communities as diverse or essentialized. These choices were affected by PTs’ positionings and impacted how PTs connected to individuals only and/or to broader society.  PTs asked questions that created space for critical discussions and facilitated awareness of diversity, yet sometimes led to overgeneralizations. The study has implications for designing telecollaborations that promote language and practices to unpack the issues of social justice.

Japanese Buddhism was introduced to the United States at the Parliament of World Religions in Chicago in 1893, but the development of Japanese American Buddhism, also known as Nikkei Buddhism, really began when Japanese migrants brought Buddhism with them to Hawaii and the continental United States during the late 19th and early 20th centuries. It has been influenced by, and has reflected, America’s sociopolitical and religious climate and the US relationship to Japan, to which generations of Japanese Americans, such as Issei (literally, first generation, referring to Japanese immigrants), Nisei (second-generation American-born offspring of the Issei), and Sansei (third generation), responded differently. While adapting to American society, Japanese American Buddhists maintained their cultural practices and ethnoreligious identity. The history of Japanese American Buddhism discussed in this article spans from the late-19th Century to the 1970s and is divided into three major periods: the pre-World War II, World War II, and the postwar eras. Japanese American Buddhism is derived from the various Buddhist organizations in Japan. The Nishi Hongwanji denomination of Jōdo Shinshū, a form of Pure Land Buddhism known as Shin Buddhism in the West, is the oldest and largest form of ethnic Japanese Buddhism in the United States. In Hawaii, Nishi Hongwanji founded the Hompa Hongwanji Mission of Hawaii (HHMH) in Honolulu in 1897. On the continental United States, it established the Buddhist Mission of North America (BMNA) in San Francisco in 1898, currently known as the Buddhist Churches of America (BCA). Other Japanese Buddhist organizations also developed in the United States at the beginning of the 20th century. They include the Jōdo-shū, another sect of Pure Land Buddhism; Higashi Hongwanji, another major denomination of Jōdoshin-shū; Sōtō-shū, a Zen Buddhist school; Shingon-shū, known as Kōyasan Buddhism; and Nichiren-shū. The characteristics of Japanese American Buddhism changed significantly during World War II, when approximately 120,000 persons of Japanese descent living in the West Coast states were incarcerated because of President Franklin D. Roosevelt’s Executive Order 9066. The postwar period witnessed a rapid transformation in the status and visibility of Japanese Buddhism in the United States. This transformation was driven by the promotion of ethnonational Buddhism by Nisei and by the growth of interest in Zen Buddhism among the general American public. The positive reception of Japanese Buddhism in the United States reflected and reinforced the transformed relationship between the United States and Japan from wartime enemies to Cold War partners. While they experienced greater receptivity and interest in Buddhism from nonethnics, they could no longer practice or espouse Jōdo Shinshū teachings or adapted practices without clarification. Debates concerning the authenticity of Jōdo Shinshū Buddhism and Japanese American Buddhist practices were interwoven within a longer history of American Orientalism. By the 1960s, Japanese American Buddhist communities were transformed by the addition of a small but vocal nonethnic membership and a new generation of Sansei Buddhists. Demands for English-speaking ministers resulted in the creation, in 1967, of the Institute of Buddhist Studies, the first graduate-level training program in the United States endorsed by Nishi Hongwanji. This article is an overview of Japanese American Buddhism with a focus on the development of the Nishi Hongwanji Shin Buddhist organizations in the United States. English scholarship on the development of other Japanese Buddhist organizations in the United States is still limited. Throughout the history of Japanese American Buddhism, Nikkei Buddhists negotiated with America’s political institutions and Christian churches, as well as with Euro-American Buddhists, over Buddhist and cultural practices to maintain and redefine their ethnoreligious tradition. Buddhist temples provided the space for them to gather and build a community of shared faith and cultural heritage, discuss their place and the role of Buddhism in American society, and express their concerns to America’s general public.

Harlington, TX, July 19 (AP)—Federal agricultural officials say that the honey bees that killed an 82-year-old rancher last week were the Africanized variety known as "killer bees." "Our lab has confirmed that the bees are Africanized," said Kim Kaplan, a Spokeswoman for the Federal Department of Agriculture in Greenbelt, MD. Final autopsy results are not yet available, but the pathologist who did the autopsy listed the preliminary cause of death as acute fluid buildup in the lungs caused by insect stings. If the cause of death is confirmed, the rancher, Lino Lopex, would be the first person killed by Africanized bees in the United States since the aggressive variety migrated into Texas in 1990. Harlington, TX, in South Texas, is about 15 miles from the Mexican border. Mr. Lopez apparently tried to drive the bees out of a wall in an abandoned house by poking the hive with a stick wrapped with a burning burlap sack. He was dead on arrival at the hospital, with about 40 stingers still attached to his body, officials said.

Clubroot disease, caused by Plasmodiophora brassicae, affects Brassica oilseed and vegetable production worldwide. This review is focused on various aspects of clubroot disease and its management, including understanding the pathogen and resistance in the host plants. Advances in genetics, molecular biology techniques and ‘omics’ research have helped to identify several major loci, QTL and genes from the Brassica genomes involved in the control of clubroot resistance. Transcriptomic studies have helped to extend our understanding of the mechanism of infection by the pathogen and the molecular basis of resistance/susceptibility in the host plants. A comprehensive understanding of the clubroot disease and host resistance would allow developing a better strategy by integrating the genetic resistance with cultural practices to manage this disease from a long-term perspective.

Florida beggarweed is native to the Western Hemisphere but is naturalized around the world. During the last century, the mechanization of agriculture has transitioned Florida beggarweed from an important forage component to a weed of significance in the coastal plain of the southeast United States. This herbaceous annual is naturalized and found in fields and disturbed areas throughout the southern United States. The characteristics that made Florida beggarweed a good forage crop also make it a formidable weed. This review describes the importance of Florida beggarweed as a weed in the southern United States and the taxonomy of this species and details the distribution throughout the world and within the United States. The ecology of Florida beggarweed and its interactions with crop plants, insects, nematodes, and plant pathogens also are summarized. Finally, management of Florida beggarweed in agricultural systems using cultural practices and herbicides is reviewed.

The urban food scape is changing rapidly. Food trucks, which are part of a wider phenomenon of street food vending, are an increasingly common sight in many cities throughout the United States and Canada. With this rise in the popularity of food trucks, the key issue of regulatory conflicts between the state, street food vending and food truck entrepreneurs, and the wider industry as a whole, has risen to the fore. Cities have responded in various ways to increased interest in mobile food vending – some have adopted encouraging and relaxed regulations, some have attempted to harness the momentum to craft a city brand, and some have rigidly regulated food trucks in response to protest by brick-and-mortar competitors. This Introduction frames the volume through its guiding questions and a variety of lenses - community economic development, social justice, postmodernism. The Introduction also outlines the sections of the volume (Democratic vs. Regulatory Practices and Spatial-Cultural Practices) and summarizes the chapters included in each section.
