Intersectionality in Psychology: Translational Science for Social Justice

Intersectionality is an analytic tool for studying and challenging complex social inequalities at the nexus of multiple systems of oppression and privilege, including race, gender, sexuality, social class, nation, age, religion, and ability. Although the term has become widely used in psychology, debates continue and confusion persists about what intersectionality actually is and how best to take an intersectional approach to psychological science. This special issue of Translational Issues in Psychological Science on intersectionality includes a range of methodological tools and theoretical perspectives that advance psychological research on intersectionality. In particular, these projects constitute psychological research that takes intersectionality’s political aspirations seriously and envisions psychology as a tool for social justice. The articles model responsible use of intersectionality through citation practices that reflect intersectionality’s origins in Black feminist thought and women of color scholar-activism, as well as through analyses that reflect intersectionality’s commitment to reflexivity, structural critique, and complexity. In this introduction, the editors reflect on intersectionality’s challenge to psychology and consider the place of translational science amid global crises and what critical psychologist Michelle Fine calls “revolting times.

When to approach novel prey cues? Social learning strategies in frog-eating bats

Animals can use different sources of information when making decisions. Foraging animals often have access to both self-acquired and socially acquired information about prey. The fringe-lipped bat, Trachops cirrhosus, hunts frogs by approaching the calls that frogs produce to attract mates.We examined howthe reliability of self-acquired prey cues affects social learning of novel prey cues. We trained bats to associate an artificial acoustic cue (mobile phone ringtone) with food rewards. Bats were assigned to treatments in which the trained cue was either an unreliable indicator of reward (rewarded 50% of the presentations) or a reliable indicator (rewarded 100% of the presentations), and they were exposed to a conspecific tutor foraging on a reliable (rewarded 100%) novel cue or to the novel cue with no tutor. Bats whose trained cue was unreliable and who had a tutor were significantly more likely to preferentially approach the novel cue when compared with bats whose trained cue was reliable, and to bats that had no tutor. Reliability of self-acquired prey cues therefore affects social learning of novel prey cues by frog-eating bats. Examining when animals use social information to learn about novel prey is key to understanding the social transmission of foraging innovations. © 2013 The Author(s) Published by the Royal Society

Experiencing Short Heat Waves Early in Development Changes Thermal Responsiveness of Turtle Embryos to Later Heat Waves

Although physiological responses to the thermal environment are most frequently investigated using constant temperatures, the incorporation of thermal variability can allow for a more accurate prediction of how thermally sensitive species respond to a rapidly changing climate. In species with temperature-dependent sex determination (TSD), developmental responses to incubation temperature are mediated by several genes involved in gonadal differentiation. Kdm6b and Dmrt1 respond to cool incubation temperatures and are associated with testis development, while Foxl2 and Cyp19A1 respond to warm incubation temperatures and are associated with ovary development. Using fluctuating incubation temperatures, we designed two studies, one investigating how conflicting thermal cues affect the timing of commitment to gonadal development, and another investigating the rapid molecular responses to conflicting thermal cues in the red-eared slider turtle (Trachemys scripta). Using gene expression as a proxy of timing of commitment to gonadal fate, results from the first study show that exposure to high amounts of conflicting thermal cues during development delays commitment to gonadal fate

A global assessment of parasite diversity in galaxiid fishes

Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus. Parasite diversity generally increased with the number of studies and individual fish examined, however studies which examined parasites from all body tissues could overcome the effects of low study effort. In order to promote further understanding of galaxiid–parasite biodiversity, we provide a series of recommendations, including the use of molecular techniques to verify parasite identity, and highlight the future roles both fish biologists and parasitologists can plapublishedVersio

Chinese-Taiwanese-Southeast Asian Triangular Relations: On Building and Rebuilding Political and Economic Assertiveness in South China Sea

China’s extraordinary economic growth and active diplomacy continue to transform greater East Asia with its sphere of influence extending to the other side of the globe through its robust development aid provisions. Taiwan, despite its political isolation with the admission of China into the United Nations as well as due to the “One China” principle managed to grow its economy as one of Asia’s tigers – a driver that led Taiwan to establish economic and cultural relations with Southeast Asian states in the absence of formal diplomatic relations. Meanwhile, Southeast Asia has seen robust and continued economic growth in the past few decades. Notwithstanding these economic gains, the present geopolitical sphere in this part of the world is becoming tenser than ever. China has been increasingly assertive in its actions in the South China Sea for years now, while Taiwan has also done a fair share of mobilisation in the contested islands. Protests from some ASEAN-member states have escalated, as manifested in their foreign policies. Within this trajectory, this paper looks into the underlying aspects of the triangular relations between China, Taiwan, and Southeast Asia

Ипотека морского судна в контексте восстановление отечественного торгового флота в Украине

Торговельне мореплавство – одна з тих галузей світової економіки, яка має найбільш швидкий розвиток у наш час. Перш за все, це пов’язано із прискоренням міжнародного товарообміну. Наростання обсягів міжнародної торгівлі, у якій прагне приймати участь також Україна, обумовлює необхідність адекватно швидкого зростання її транспортної галузі. Попри значний транспортний потенціал, що має Україна, багато в чому завдячуючи її географічному положенню, стан вітчизняного транспортного комплексу й, особливо, його морської ланки, потребує покращення. Це, в свою чергу, безпосередньо залежить від правового регулювання, що впорядковує такі процеси

A novel retinoblastoma therapy from genomic and epigenetic analyses.

Retinoblastoma is an aggressive childhood cancer of the developing retina that is initiated by the biallelic loss of RB1. Tumours progress very quickly following RB1 inactivation but the underlying mechanism is not known. Here we show that the retinoblastoma genome is stable, but that multiple cancer pathways can be epigenetically deregulated. To identify the mutations that cooperate with RB1 loss, we performed whole-genome sequencing of retinoblastomas. The overall mutational rate was very low; RB1 was the only known cancer gene mutated. We then evaluated the role of RB1 in genome stability and considered non-genetic mechanisms of cancer pathway deregulation. For example, the proto-oncogene SYK is upregulated in retinoblastoma and is required for tumour cell survival. Targeting SYK with a small-molecule inhibitor induced retinoblastoma tumour cell death in vitro and in vivo. Thus, retinoblastomas may develop quickly as a result of the epigenetic deregulation of key cancer pathways as a direct or indirect result of RB1 loss

Talking About and Preparing for Death Among Older Adults

Experts on end-of-life issues recommend that individuals make preparations – living will, health care proxy, last will and testament, and memorial service – for their eventual death (Bischoff, Sudore, Miao, Boscardin, & Smith, 2013). While these experts further encourage a broader process of advance care planning, which includes conversations with loved ones, many individuals are reticent to engage in such end-of-life conversations (Brinkman-Stoppelenburg, Rietjens, & Heide, 2014). The purpose of this study was to investigate relationships between older adults’ comfort having end-of-life discussions with family members, death preparation, and comfort with their end-of-life plans. Community-dwelling older adults (N = 354) participated in an interview survey about end-of-life issues. Comfort with having end-of-life discussions with family was associated with greater death preparation and comfort with end-of-life plans. Death preparation mediated the relationship between comfort with end-of-life discussions and comfort with end-of-life plans. Overall, the results are consistent with the notion that individuals who are more comfortable discussing their end-of-life plans with loved ones engage in greater death preparation and thereby feel a greater sense of contentment with their plans for death
