Remembering Lucky Dragon,re-membering Bikini: worlding the Anthropocene through transpacific nuclear modernity

This paper examines two recent Godzilla-themed cultural artefacts that highlight the entanglement between nuclear weaponry and nuclear energy: first, the 60th anniversary Godzilla exhibit at the Tokyo Metropolitan Daigo Fukuryū Maru Exhibition Hall; second, the 2014 American Godzilla directed by Gareth Edwards. This paper frames these two distinctive post-Fukushima cultural texts as memory work that mediates post-WWII genealogies of nuclear weaponry and nuclear power as constitutive elements of U.S. militarism and transpacific technological modernity. Specifically, this paper foregrounds how these two recent cultural texts, produced at different Pacific shores, bring the complexity of the often-absented Pacific back into focus. By enacting what Rob Wilson and Chris Connery call ‘worlding’ to make sense of divergent representations of the tragic Lucky Dragon/Bikini incident that decidedly informed the creation of the original Japanese Gojira [1954. Film. Directed by Honda Ishiro. Japan: Toho Co., Ltd.], this paper analyses geopolitical figurations of the Pacific and its peoples in both the specific context of this tragic incident and the broader formation of transpacific nuclear modernity. In so doing, this paper unravels the ways in which these divergent representations grapple with nuclear modernity’s reordering of necropolitics and biopolitics and its effects: specifically, the ways in which the renarration of death-making nuclear technology as a technology of good life conveniently erases the victims of nuclear weapons, radioactive fallout, and nuclear waste that the reproduction of U.S. nuclearism depends on and continues to produce.     

The Planned Happenstance Career Inventory: A Cross‐Cultural Comparison

This study examined the measurement invariance and latent mean difference of an English version (J. H. Lee et al., 2017) of the Planned Happenstance Career Inventory (PHCI; B. Kim, Jung, et al., 2014) across cultures. Participants were 262 American and 291 South Korean undergraduates. Measurement invariance results indicated that the 5‐factor structure was adequate for both groups and that conditions for configural, metric, and partial intercept invariance were met. Latent mean analysis was used to compare the mean scores of the PHCI skills (curiosity, flexibility, persistence, optimism, and risk taking). The latent means of curiosity, flexibility, persistence, and optimism were higher among South Korean undergraduates, but no significant difference was found regarding risk taking. Career counselors should consider differences in planned happenstance perceptions across cultures to provide better career guidance. Future studies are needed to verify the distinctive nature of flexibility by replicating the factor structure of the PHCI with other samples.     

Analytical binomial lookback options with double-exponential jumps

We study the problem of the convergence of the adjusted binomial lookback option in double-exponential jump diffusion models. By using the results of [Dai, M., (2000). A modified binomial tree method for currency lookback options. Acta Mathematica Sinica, 16, 445–454; Kou, S., & Wang, H. (2004). Option pricing under a double exponential jump diffusion model. Management Science, 50, 1178–1192] and [Park, H.S., Kim, K.I., & Qian, X. (2009). A Mathematical modeling for the Lookback option with jump diffusion using Binomial tree method. Journal of Computational and Applied Mathematics, preprint], we show the equivalence between the adjusted binomial tree method and the explicit difference scheme. The convergence is also theoretically proved through the notion of viscosity solution. Numerical results coincide with the theoretical results.     

Imputation using response probability

The authors propose a new ratio imputation method using response probability. Their estimator can be justified either under the response model or under the imputation model; it is thus doubly protected against the failure of either of these models. The authors also propose a variance estimator that can be justified under the two models. Their methodology is applicable whether the response probabilities are estimated or known. A small simulation study illustrates their technique.     

A genetic algorithm approach to developing the multi-echelon reverse logistics network for product returns

Traditionally, product returns have been viewed as an unavoidable cost of doing business, forfeiting any chance of cost savings. As cost pressures continue to mount in this era of economic downturns, a growing number of firms have begun to explore the possibility of managing product returns in a more cost-efficient manner. However, few studies have addressed the problem of determining the number and location of centralized return centers (i.e., reverse consolidation points) where returned products from retailers or end-customers were collected, sorted, and consolidated into a large shipment destined for manufacturers’ or distributors’ repair facilities. To fill the void in such a line of research, this paper proposes a nonlinear mixed-integer programming model and a genetic algorithm that can solve the reverse logistics problem involving product returns. The usefulness of the proposed model and algorithm was validated by its application to an illustrative example dealing with products returned from online sales.     

Causal inferences from many experiments

The underlying statistical concept that animates empirical strategies for extracting causal inferences from observational data is that observational data may be adjusted to resemble data that might have originated from a randomized experiment. This idea has driven the literature on matching methods. We explore an un-mined idea for making causal inferences with observational data – that any given observational study may contain a large number of indistinguishably balanced matched designs. We demonstrate how the absence of a unique best solution presents an opportunity for greater information retrieval in causal inference analysis based on the principle that many solutions teach us more about a given scientific hypothesis than a single study and improves our discernment with observational studies. The implementation can be achieved by integrating the statistical theories and models within a computational optimization framework that embodies the statistical foundations and reasoning.     

Do Children With Gender Dysphoria Have Intense/Obsessional Interests?

This study examined whether children clinically referred for gender dysphoria (GD) show increased symptoms of autism spectrum disorder (ASD). Circumscribed preoccupations or intense interests were considered as overlapping symptoms expressed in GD and ASD. In gender-referred children (n = 534; 82.2% male) and their siblings (n = 419; 57.5% male), we examined Items 9 and 66 on the Child Behavior Checklist, which measure obsessions and compulsions, respectively. Non-GD clinic-referred (n = 1,201; 48.5% male) and nonreferred (n = 1,201; 48.5% male) children were also examined. Gender-referred children were elevated compared to all other groups for Item 9, and compared to siblings and nonreferred children for Item 66. A gender-related theme was significantly more common for gender-referred boys than male siblings on Item 9 only. A gender-related theme was not significantly more common for gender-referred girls compared to their female siblings on either item. The findings for Item 9 support the idea that children with GD show an elevation in obsessional interests. For gender-referred boys in particular, gender-related themes constituted more than half of the examples provided by their mothers. Intense/obsessional interests in children with GD may be one of the factors underlying the purported link between GD and ASD.     

The social ecology of the Columbine High School shootings

The Columbine High School shooting in 1999 prompted school officials and policy-makers to create and implement programs and policies that would prevent violence in school and ensure school safety. Ten years have passed since the Columbine shooting; however, debates concerning risk factors for the shootings continue to ensue. The focus of this article is to examine the Columbine school shootings within the context of Bronfenbrenner's (1994) ecological systems analysis. We examine the most commonly identified risk factors, which operate within five systems levels: chrono-, macro-, exo-, meso-, and microsystems, and draw implications for school-based practice and policy.     

Surviving grief: An analysis of the exchange of hope in online grief communities

Online grief communities represent relatively new forms of peer support. However, the degree to which they are helpful for individual grieving processes is unknown. To date, no research has evaluated the type or quality of support exchanged in online grief communities. To begin to address these questions, this study analyzed 564 messages from internet grief websites to: (1) classify the type of helping skills used, and (2) extract themes contained in the content of the messages. Messages selected for analysis were the first response to an original post, assuming they would be the first effort to provide support to a grieving individual. Results revealed a majority of responses contained self-disclosure. Themes in the messages suggested provision of more than "one-way" support; messages themes also included exchanging hope for the future by sharing one's own story, validating the grief experience, providing resources, and exchanging psychosocial support. Clinical implications and research recommendations are discussed.
