Abstract The Spotted Lantern Fly (SLF), Lycorma delicatula (Hemiptera: Fulgoridae), is a sap feeding pest native to southeast Asia that has become a global biosecurity threat following invasions into South Korea, Japan, and the United States in the last two decades. Environmental niche modelling has demonstrated considerable potential for further range expansions, including into Australia and Europe. Further analysis on the potential seasonal life-history and survival of this pest in its invasive range can inform monitoring programs and is a next step in biosecurity preparedness. Here, we incorporated eco-physiological information on the development and survival of SLF life stages across temperature regimes. Using gridded climatic data, we then mapped the developmental sequence of SLF across ranges already occupied in China, South Korea, and the United States, as well as uninvaded ranges in Australia and Europe. The model was able to capture global observations of the seasonal appearance of SLF and highlight regional and seasonal vulnerabilities in regions at risk of invasion. Policy makers can use these results to make science-based biosecurity decisions and target preparedness activities through improved life-history predictions in its invasive range.

The Argentine Black and White Tegu (Salvator merianae, formerly Tupinambis merianae) is a large lizard from South America. Now established and invasive in southern Florida, and it poses threats to populations of many native species. Models suggest much of the southern United States may contain suitable temperature regimes for this species, yet there is considerable uncertainty regarding either the potential for range expansion northward out of tropical and subtropical zones or the potential for the species establishing elsewhere following additional independent introductions. We evaluated survival, body temperature, duration and timing of winter dormancy, and health of wild-caught tegus from southern Florida held in semi-natural enclosures for over a year in Auburn, Alabama (> 900 km northwest of capture location). Nine of twelve lizards emerged from winter dormancy and seven survived the greater-than-one-year duration of the study. Average length of dormancy (176 d) was greater than that reported in the native range or for invasive populations in southern Florida and females remained dormant longer than males. Tegus grew rapidly throughout the study and the presence of sperm in the testes of males and previtellogenic or early vitellogenic follicles in female ovaries at the end of our study suggest the animals would have been capable of reproduction the following spring. The survival and overall health of the majority of adult tegus in our study suggests weather and climate patterns are unlikely to prevent survival following introduction in many areas of the United States far from their current invasive range.

Good afternoon. President Kim, members of the Korean delegation, let me first say again what a privilege it has been to welcome President Kim back to the United States and here to the White House. His remarkable life history reminds us that from Seoul to its sister city, San Francisco, people everywhere share the same aspirations—for freedom, for peace, for the opportunity of prosperity.

The Voice

Transnational films representing intimacy and inequality disrupt and disgust Western spectators. When wounded bodies within poverty entangle with healthy wealthy bodies in sex, romance and care, fear and hatred combine with desire and fetishism. Works from the Philippines, South Korea, and independents from the United States and France may not be made for the West and may not make use of Hollywood traditions. Rather, they demand recognition for the knowledge they produce beyond our existing frames. They challenge us to go beyond passive consumption, or introspection of ourselves as spectators, for they represent new ways of world-making we cannot unsee, unhear, or unfeel. The spectator is redirected to go beyond the rapture of consuming the other to the rupture that arises from witnessing pain and suffering. Self-displacement is what proximity to intimate inequality in cinema ultimately compels and demands so as to establish an ethical way of relating to others. In undoing the spectator, the voice of the transnational filmmaker emerges. Not only do we need to listen to filmmakers from outside Hollywood who unflinchingly engage the inexpressibility of difference, we need to make room for critics and theorists who prioritize the subjectivities of others. When the demographics of filmmakers and film scholars are not as diverse as its spectators, films narrow our worldviews. To recognize our culpability in the denigration of others unleashes the power of cinema. The unbearability of stories we don’t want to watch and don’t want to feel must be borne.

Latent Profiles

This cross-national research investigated nationally representative adolescents from South Korea and the United States, explored similarities and differences in latent profiles of bullying victimization between countries, and examined individual- and school-level variables that predict such latent profiles supported by the Social Disorganization Theory. The fourth-grade sample of the 2015 Trends in International Mathematics and Science Study from South Korea ( N = 4,669) and the United States ( N = 10,029) was used to conduct a latent profile analysis based on eight items of the bullying victimization questionnaire. Multilevel logistic regression was conducted using latent profiles as dependent variables. Independent variables include individual-level (material goods, school absence, academic interest, school belonging) and school-level (concentration of affluent families, school resources, the severity of delinquency, academic commitment) factors. More similarities existed than differences in the latent groups of bullying victimization between South Korea ( rare, low-moderate, verbal-relational-physical, and multi-risk) and the United States ( rare, low-moderate, verbal-relational, and multi-risk). Evidence for school-level variables as predictors of bullying victimization profiles was stronger for adolescents in the United States, with a concentration of affluent families and severity of delinquency being significant in four of the six models. For the South Korean sample, the severity of delinquency predicted bullying victimization in only one model. Examination of both individual- and school-level factors that predict unique bullying victimization experiences grounded in Social Disorganization Theory may be informative for addressing key areas of intervention—especially at the school-level context in which victimization primarily takes place and where anti-bullying intervention programs are often provided.
