A Nearly Exact Discretization Scheme for the FitzHugh–Nagumo Model
No full textIn this paper, we apply the nearly exact discretization schemes to propose a discrete model for the FitzHugh–Nagumo model. We show that the discrete model obtained preserves the dynamics and the known features of the continuous FitzHugh–Nagumo model. We do so by performing distance-based and probability-based similarity analysis. Additionally, a sensitivity analysis is also performed to analyze the most influential parameters of the discrete system
Dissemination of a Dissonance-Based Body Image Promotion Program in Church Settings: A Preliminary Controlled Pilot Study with Adult Women
No full textAdult women report significant body dissatisfaction yet are often overlooked in body image promotion programs. Although few venues afford opportune settings for intervening with adult women, the church serves as a regular meeting place for many in the South of the United States. This study tested a dissonance-based body image program, Reclaiming Beauty (RB), adapted for adult women in church settings. Six groups (n = 30) were led by two trained church leaders (peer-led) and three groups (n = 21) were led by a trained peer leader and a researcher (researcher-co-led). RB participants, aged 30–77 years (M = 53.1 ± 12.7), completed assessments pre-intervention, immediately post-intervention, and 6 months post-intervention. Waitlist-controls (n = 31) completed assessments at time intervals consistent with intervention participants. RB participants reported significantly decreased thin-ideal internalization, body surveillance, and eating psychopathology at post-intervention and at 6 months post-intervention relative to controls. RB participants also reported significantly increased body satisfaction immediately post-intervention relative to controls, but this was not significant at 6 months post-intervention. Peer-led groups outperformed researcher-co-led groups on body surveillance at 6 months, but RB conditions did not otherwise differ. Our findings provide preliminary support for the dissemination of a culturally-modified dissonance-based body image program to adult women in church settings
The Gospel of Peter
Get PDFSome early editions divided the Gospel of Peter into fourteen chapters following the numbering system created by A. Harnack, while others divided it into sixty verses following the system devised by J.A. Robinson. Scholars have followed the practice of using both, or more recently, use only Robinson’s numbering. In our translation we follow both. The translation below uses the Greek text in Bart D. Ehrman and Zlatko Pleše, The Apocryphal Gospels: Texts and Translations (Oxford University Press, 2011), pp. 378-386
Is Green the New Red? Marxism, Ecology, and Contemporary Architectural Theory
Get PDFThis essay examines the role of Marxist concepts in recent architectural theories of ecology using two architecture firms, Estudio Teddy Cruz and Sauerbruch Hutton (SH), as case studies. In their writings, Cruz and SH mobilize the critique of capital, a dialectical materialist understanding of history, and the Frankfurt School’s critique of functionalist culture for the theorization of sustainable design. Their work has two vital ramifications for current sustainability discourses in two different fields which this essay seeks to bridge. For Marxist theorists concerned about ecology but averse to Western Marxism because of its supposed idealism, Cruz and SH show anew the importance of aesthetic concerns to conceptions of the environment. For design scholars accustomed to thinking of Marxism as having been absorbed into broader debates about cultural studies, the architects’ theories have the potential to recentralize the left-wing inheritance through its adaptation to concerns of ecology. In addition, in the essay’s conclusion, I reflect briefly, as a suggestion for further research, on how Cruz’s and SH’s architectural practice and theories might productively be analyzed in light of the terms of the Adorno-Benjamin debate of the 1930s over the political status of the cultural products of capital. Can eighty-year old discussions of the potentially revolutionary and retrograde qualities of mass cultural objects be relevant to radical thought in the age of climate change
Becoming MSM: Sexual Minorities and Public Health Regimes in Vietnam
Get PDFThis article explores the discursive and practical marking of male sexual minorities in Vietnam, as targets of a series of biopolitical regimes whose aim, ostensibly, was and is to secure the health and wellbeing of the population (from the French colonial period to the present), regimes which linked biology, technoscientific intervention and normative sexuality in the service of state power. Campaigns against sex workers, drug users, and briefly male sexual minorities, seriously exacerbated the marginalization and stigmatization of these groups, particularly with the emergence of HIV/AIDS in Vietnam in 1990. This article also considers how the contemporary apparatus constructed to combat the HIV/AIDS epidemic, one funded by the US, did not do away with these old forms, but reinscribed them with new language within a new regime that prioritizes quantification and technoscience
Culturable Root Endophyte Communities are Shaped by Both Warming and Plant Host Identity in the Rocky Mountains, USA
Get PDFUnderstanding the biogeographic patterns of root-associated fungi and their sensitivity to temperature may improve predictions of future changes in terrestrial biodiversity and associated ecosystem processes, but data are currently limited. Anticipating change will require combining observational data, which predict how climatic factors limit current species distributions, with direct manipulations of climate, which can isolate responses to specific climate variables. Root endophytes are common symbionts of plants, particularly in arctic and alpine environments, yet their responses to climate warming are not resolved. Here, we directly cultured endophytic fungi from roots collected along altitudinal gradients in replicated mountain watersheds and from a 27 y field warming experiment in the Rocky Mountains, USA, to improve understanding of climate impacts on fungal root endophytes. Fungal taxa that were common at high elevations declined most under climate warming, whereas low elevation dominants responded neutrally or increased with experimental warming. Altitudinal gradients in fungal communities were strongly specific to the plant host species. Specifically, Poa species had 25–60% greater fungal isolate abundance and 25–38% greater fungal diversity at high elevations than at low elevation sites. In contrast, Festuca thurberi had 64% lower fungal diversity on roots at high elevation than at low elevation. Our results help to improve understanding of the potential for climate change to alter plant-fungal interactions in mountain ecosystems

Ancient DNA of the Pygmy Marmoset Type Specimen \u3cem\u3eCebuella pygmaea\u3c/em\u3e (Spix, 1823) Resolves a Taxonomic Conundrum
Get PDFThe pygmy marmoset, the smallest of the anthropoid primates, has a broad distribution in Western Amazonia. Recent studies using molecular and morphological data have identified two distinct species separated by the Napo and Solimões-Amazonas rivers. However, reconciling this new biological evidence with current taxonomy, i.e., two subspecies, Cebuella pygmaea pygmaea (Spix, 1823) and Cebuella pygmaea niveiventris (Lönnberg, 1940), was problematic given the uncertainty as to whether Spix’s pygmy marmoset (Cebuella pygmaea pygmaea) was collected north or south of the Napo and Solimões-Amazonas rivers, making it unclear to which of the two newly revealed species the name pygmaea would apply. Here, we present the first molecular data from Spix’s type specimen of Cebuella pygmaea, as well as novel mitochondrial genomes from modern pygmy marmosets sampled near the type locality (Tabatinga) on both sides of the river. With these data, we can confirm the correct names of the two species identified, i.e., C. pygmaea for animals north of the Napo and Solimões-Amazonas rivers and C. niveiventris for animals south of these two rivers. Phylogenetic analyses of the novel genetic data placed into the context of cytochrome b gene sequences from across the range of pygmy marmosets further led us to re-evaluate the geographical distribution for the two Cebuella species. We dated the split of these two species to 2.54 million years ago. We discuss additional, more recent, subdivisions within each lineage, as well as potential contact zones between the two species in the headwaters of these rivers
Social Autonomy ≠ Social Empowerment: The Social Self-Restriction Model
Get PDFThis paper introduces the social self-restriction (SSR) model, which highlights a drawback associated with the increasingly accessible privilege of social autonomy. Social autonomy enables individuals to connect with preferred social partners and avoid undesirable others. The benefits of social autonomy are undeniable; however, the SSR model makes the novel assertion that people tend to exercise social autonomy in ways that ultimately constrain their potential for social empowerment—a higher-order form of personal freedom. Attaining the ideal of high social empowerment requires both high social autonomy and high social adaptability. People with high social adaptability can feel reasonably comfortable and act competently in social environments they did not choose to inhabit. Unfortunately, people with high social autonomy are unlikely to possess high social adaptability. We propose that social autonomy undermines social adaptability by tempting people to avoid social challenges and socialize selectively with similar others in familiar contexts, a habit that limits social skill development, promotes social intolerance, and distorts social perceptions. In essence, we argue that social autonomy allows people to live in their social comfort zones, at the cost of restricting their social range. Our discussion of the SSR model incorporates evidence and perspectives from a broad range of academic disciplines, and includes consideration of opportunities for future research
