AbstractHaemaphysalis longicornis, the Asian longhorned (or bush) tick has been detected on a sheep in August 2017 in Hunterdon County, New Jersey. By October 26, 2018, this tick has been detected in 44 counties in 9 states along the Atlantic coast of the United States, with the first detection backdated to 2010. Here, I use a simple rule-based climate envelope model, based on a prior analysis in New Zealand, to provide a preliminary analysis of the potential range of this introduced tick species in North America. After validating this model against the counties where the tick has been already detected, I highlight the counties where this tick might cause considerable economic harm. I discuss the many limitations of this simple approach, and potential remedies for these limitations, and more sophisticated approaches. Finally, I conclude that substantial areas of the US, especially along the Gulf and Atlantic coast, are suitable for the establishment of this tick, putting millions of heads of livestock potentially at risk.

AbstractThe 'special relationship' between the United States and Israel has endured for more than four decades and is one of the more anomalous global political alliances. Conventional explanations have consistently failed to elucidate the underlying nuances of a relationship that has endured the transition from the Cold War to the unipolar world to the present day 'war on terror' and is often costly to the USA in economic and geostrategic terms. This article argues that the nebulous but still valuable concept of political culture provides a crucial ingredient to any understanding of the special relationship. In perceiving their society to be a beacon of what they like to call 'freedom' and 'democracy,' in a world in which these values are largely absent, Americans have been encouraged to believe that they share a political kinship with societies similarly imbued and that they have an obligation to assist where such values are under threat. This process of identification is reinforced by the activities of the pro-Israel lobby and the beliefs of America's increasing number of Christian Evangelicals who support Israel for largely religious reasons. It is the many dimensions of this cultural identification that sets Israel apart from other nations and forms the bedrock of the US-Israeli special relationship.

Science education in the United States has undergone a profound shift in emphasis away from lecture-based and knowledge-based approaches towards more hands-on platforms with emphasis on skill training and maximizing feedback. Of central importance in this movement has been the concept of scientific teaching: the idea of treating education like a scientific subject by performing experiments on educational outcomes. In the last two decades, a wealth of research has been conducted using this principle to examine the effectiveness of a wide range of pedagogical techniques. Of the many methods used to deliver class content to students, active learning has emerged as one of the most powerful. Another critical development in scientific teaching has been the realization of a wide range of standardized assessment tools for quantifying various student outcomes. Despite the convincing nature of empirical evidence in favor of the utility of both scientific teaching and active learning, dissemination of these platforms in average teaching practices has been slow, even in the US. This article reviews the many advances and challenges of scientific teaching reform, ending with a brief commentary of reform experiences in the US and how these may impact East Asia in the near future.

Abstract While it has become accepted that norms can act in institution-like ways, a highly valued norm that has not been examined is free speech. Can free speech be conceptualised as acting in institution-like ways? If it can, what does this illuminate about processes of policy change? I analyse policy change between 2001 and 2011 in the United States, the United Kingdom and Australia, a period during which significant new limits were introduced on free speech in relation to national security. In addition to showing how free speech acted in institution-like ways, the analysis suggests three implications: norms can both act in institution-like ways and be subject to change in interaction with other institutions; a broad, cultural level institution can mask policy change at the narrow, rule-based level even where the latter contradicts the former; and complexity and variation in speech regulation can be understood as consequences of the to-be-expected variability in the institutionalisation of a norm.

This article aims to unsettle a pervasive cultural distinction between gambling – on one hand - and the competitive games of society – on the other - by exploring the role of whiteness as a form of symbolic capital in two different but closely related nations. Rather than following Pierre Bourdieu in relegating gambling to the constitutive outside of neo-liberal cultural and political economies, where sub-proletarian subjects are rendered simultaneously the object of an academic gaze and of public worrying about problem gambling, I will explore racialized dimensions of the many games of strength, skill and chance that constitute everyday culture in ex-settler-colonial nations. Comparative discussion highlights the role of gambling in mediating and transforming relationships of sovereignty between Indigenous and non-Indigenous citizens in Australia and the US.

Until recently, only two haemaphysaline species, Haemaphysalischordeilis (Packard, 1869) and Haemaphysalisleporispalustris (Packard, 1869), were known to occur in the United States, and neither was considered to be of significant medical or veterinary importance. In 2017–2018 established populations of the Asian longhorned tick, Haemaphysalislongicornis Neumann, 1901, were detected in the eastern US for the first time. Haemaphysalislongicornis has the potential to be a significant threat to human and animal health, and the urgent need to determine the full extent of its distribution and host range requires availability of a straightforward and practical guide to differentiate it from native species. We created a pictorial dichotomous key to all stages of Haemaphysalis spp. known to occur in North America with scanning electron photomicrographs of all H.longicornis life stages, including rarely seen males, to aid researchers in differentiating these species. The largely Neotropical species Haemaphysalisjuxtakochi Cooley, 1946, with established populations in Mexico and sporadic detections in the US on migrating birds is also included.

All species of sawfish are listed by the International Union for the Conservation of Nature (IUCN) as endangered or critically endangered. In fact, the smalltooth sawfish Pristis pectinata, and the largetooth sawfish Pristis pristis, have been declared to be regionally and locally extinct from the US Atlantic coast and the Gulf of California, Mexico, respectively, likely due to overfishing. However, here we dispute these claims by illustrating how lack of existence of a given species within a region can be misconstrued as evidence for extinction.

In “For Public Sociology” and other essays, Michael Burawoy acknowledges that the national sociologies of countries other than the US (e.g. Brazil, Norway, South Africa) differ substantially from the US case. The balance and dynamics among the four types of sociology, the timing and phases of the historical development of the discipline and the challenges that face the discipline, are some of the many ways sociology differs from country to country (2005a: 20-22; 2005c: 382-4, 2005d: 423-4). Canada is a particularly interesting case because of its geographic proximity and close economic and cultural ties to the United States. Canadian sociology has been deeply influenced by American sociology, but has always stood in an uneasy intellectual and political relationship to the US version of the discipline (Hiller 1982; Brym with Fox 1989; Cormier 2004; McLaughlin 2005). A serious discussion of the possibilities and challenges for a public sociology in Canada requires an analysis of the historical and sociological specificity of the Canadian version of the discipline, something we hope to offer here in this introduction as well as in the papers to follow.

The United States of America is a country with a long tradition of migration in which second- and third-generation Americans have been assimilated into a cultural ‘melting pot.’ This multicultural reality highlights the many varied elements of superdiversity that make up the complex characteristics of contemporary society in this country. In the present study, the authors seek to identify some of these elements of superdiversity by viewing them qualitatively through the eyes and experiences of offspring of multicultural transnational couples with a migratory background living in the US. The primary data collection consisted of 90-minute personal interviews with 29 subjects between 15 and 30 years of age who reside in the state of Florida and whose parents identified as being from different national origins. The results show significant differences in interpretations between the classic definitions of nationality and cultural identity, highlighting personal networks as a dimension to be taken into account for the analysis of superdiversity. Implications for practice and some directions for future research are discussed.

Shah Mohammad Reza Pahlavi tried in his visit to Washington to give the impression to the US administration that he was able to protect the interests of the United States in Iran and in the whole Arabian Gulf and the Middle East. The visit of the Shah represented a new turning point in the history of the Iranian - US relations. It included the discussion of issues concerning both countries, especially the issue of arms and the production and sale of Iranian oil after the announcement of the British government's desire to withdraw from the Gulf region within three years. The American leaders focused on meeting the demands of the Shah, specifically the military ones, to discuss oil production topics and methods of exporting and cooperation with US oil companies, have expressed American sympathy in dealing with the many issues.
