Social Climate Science: A New Vista for Psychological Science

The recent Paris Agreement to limit greenhouse gas emissions, adopted by 195 nations at the 2015 United Nations Climate Change Conference, signaled unprecedented commitment by world leaders to address the human social aspects of climate change. Indeed, climate change increasingly is recognized by scientists and policymakers as a social issue requiring social solutions. However, whereas psychological research on intrapersonal and some group-level processes (e.g., political polarization of climate beliefs) has flourished, research into other social processes—such as an understanding of how nonpartisan social identities, cultural ideologies, and group hierarchies shape public engagement on climate change—has received substantially less attention. In this article, we take stock of current psychological approaches to the study of climate change to explore what is “social” about climate change from the perspective of psychology. Drawing from current interdisciplinary perspectives and emerging empirical findings within psychology, we identify four distinct features of climate change and three sets of psychological processes evoked by these features that are fundamentally social and shape both individual and group responses to climate change. Finally, we consider how a more nuanced understanding of the social underpinnings of climate change can stimulate new questions and advance theory within psychology.
Putative Domain-Domain Interactions in the Vesicular Stomatitis Virus L Polymerase Protein Appendage Region

ABSTRACT The multidomain polymerase protein (L) of nonsegmented negative-strand (NNS) RNA viruses catalyzes transcription and replication of the virus genome. The N-terminal half of the protein forms a ring-like polymerase structure, while the C-terminal half encoding viral mRNA transcript modifications consists of a flexible appendage with three distinct globular domains. To gain insight into putative transient interactions between L domains during viral RNA synthesis, we exchanged each of the four distinct regions encompassing the appendage region of vesicular stomatitis virus (VSV) Indiana serotype L protein with their counterparts from VSV New Jersey and analyzed effects on virus polymerase activity in a minigenome system. The methyltransferase domain exchange yielded a fully active polymerase protein, which functioned as well as wild-type L in the context of a recombinant virus. Exchange of the downstream C-terminal nonconserved region abolished activity, but coexchanging it with the methyltransferase domain generated a polymerase favoring replicase over transcriptase activity, providing strong evidence of interaction between these two regions. Exchange of the capping enzyme domain or the adjacent nonconserved region thought to function as an “unstructured” linker also abrogated polymerase activity even when either domain was coexchanged with other appendage domains. Further probing of the putative linker segment using in-frame enhanced green fluorescent protein (EGFP) insertions similarly abrogated activity. We discuss the implications of these findings with regard to L protein appendage domain structure and putative domain-domain interactions required for polymerase function. IMPORTANCE NNS viruses include many well-known human pathogens (e.g., rabies, measles, and Ebola viruses), as well as emerging viral threats (e.g., Nipah and Hendra viruses). These viruses all encode a large L polymerase protein similarly organized into multiple domains that work in concert to enable virus genome transcription and replication. But how the unique L protein carries out the multiplicity of individual steps in these two distinct processes is poorly understood. Using two different approaches, i.e., exchanging individual domains in the C-terminal appendage region of the protein between two closely related VSV serotypes and inserting unrelated protein domains, we shed light on requirements for domain-domain interactions and domain contiguity in polymerase function. These findings further our understanding of the conformational dynamics of NNS L polymerase proteins, which play an essential role in the pathogenic properties of these viruses and represent attractive targets for the development of antiviral measures.
Transcatheter closure of the patent foramen ovale in children: intermediate-term follow-up results

Abstract The patent foramen ovale is almost a normal anatomical hole between the atria with ~30% incidence in the general population. It has been suggested that the patent foramen ovale is the cause of some neurological events, which is explained by paradoxical embolism. Transcatheter closure of the patent foramen ovale is a common procedure in adult patients with cerebral ischaemic events, but there are limited data investigating the results in children. Between January, 2005 and February, 2014, 17 patients’ patent foramen ovales were closed by the transcatheter approach in our department. The indications for closure were transient ischaemic attack in 10 patients, stroke in four patients, and migraine in three patients. The mean age and mean weight at the time of the procedure were 11.1±3.7 years and 42.1±15.4 kg, respectively. We asked our patients whether their previous ailments continued. All patients responded to the study survey. In 15 patients, ailments did not continue after patent foramen ovale closure and they significantly decreased in two of them. We suggest that under the right conditions device closure of the patent foramen ovale is a safe solution for these cryptogenic ischaemic events and migraine.
Use of mitomycin C in repeat dacryocystorhinostomy.

PURPOSE The usefulness of a single intraoperative application of mitomycin C was investigated in repeat dacryocystorhinostomy for membranous failure. METHODS Mitomycin C (0.3 mg/ml for 3 minutes) was topically applied to the fistula site in eight patients undergoing repeat dacryocystorhinostomy for membranous failure. RESULTS All patients remain asymptomatic and anatomic patency confirmed by probe and irrigation with a mean follow-up period of 14.6 months (range, 6-26 months). No postoperative complications associated with the use of mitomycin C were observed. CONCLUSIONS In patients who do not maintain a patent fistula after dacryocystorhinostomy because of membranous occlusion of the rhinostomy site, the adjunctive use of mitomycin C may increase the success rate of repeat dacryocystorhinostomy.
Relationships of serum illicit drug concentrations during pregnancy to maternal nutritional status.

Findings reported are for a subset of African American subjects, residing in the urban area of Washington, D. C. , who participated in a Program Project designed to study nutrition, other factors, and the outcome of pregnancy. Fasting blood samples, drawn during each trimester of pregnancy and at delivery, were screened for concentrations of cocaine, phencyclidine (PCP) and marijuana. Since substance abusers are expected to consume inadequate diets, these samples were also analyzed for serum folate, vitamin B12, ferritin and ascorbic acid. Data for these biochemical variables were compared for subjects whose serum values for drugs were either above or below the drug screening threshold concentrations established by ADAMHA/NIDA. Pearson's correlations were used to determine relationships between pregnancy outcome variables and maternal serum drug concentrations. Blood samples drawn at delivery showed higher maternal: cord ratios (mean +/- SEM) for marijuana (3.3 +/- 2.2) and PCP (2.9 +/- 1.0) than for cocaine (1.0 +/- 0.2). The subjects whose serum values were above the ADAMHA/NIDA ranges for marijuana, PCP and cocaine had concentrations of folate and ferritin that were significantly less than those of subjects with lower serum drug levels (P < or = 0.05). High maternal serum concentrations of illicit drugs were accompanied by a significant increase in leukocyte count (P < or = 0.05). The level of maternal cocaine during the third trimester was inversely correlated with birthweight (r = -0.29; n = 52; P = 0.038) and head circumference (r = -0.28; n = 52; P = 0.047).

Enhanced Physical Activity Improves Selected Outcomes in Children With ADHD

This review examines associations between physical activity (PA) and cognitive, behavioral, and physiological outcomes in children with attention-deficit/hyperactivity disorder (ADHD). We reviewed studies on participants ≤18 years old, published in English between January 1998 and December 2014, in PubMed, CINAHL, PsycINFO, and Cochrane Reviews. Twenty-six studies were grouped into two categories: those that did and did not account for effects of ADHD medications. The first category showed lower levels of PA and improved cognitive and behavioral outcomes in youth whose ADHD was treated with medications. The second category showed a positive association between PA levels and cognitive and behavioral outcomes in youth whose ADHD was not treated with medications. For both categories of studies, results were inconclusive regarding physiological outcomes. Randomized controlled trials are needed to better clarify the relationship between PA and outcomes in youth with ADHD, and particularly to understand the impact of ADHD medications on that relationship.
Marginal Bone Loss in Implants Placed in the Maxillary Sinus Grafted With Anorganic Bovine Bone: A Prospective Clinical and Radiographic Study.

BACKGROUND Sinus elevation is a reliable and often-used technique. Success of implants placed in such situations, even with bone substitutes alone, prompted the authors of this study to strive for bone loss close to zero and research variables that cause higher or lower rates of resorption. The objective of this study is to evaluate survival rates and marginal bone loss (MBL) around implants placed in sites treated with maxillary sinus augmentation using anorganic bovine bone (ABB), and identify surgical and prosthetic prognostic variables. METHODS Fifty-five implants were placed in 30 grafted maxillary sinuses in 24 patients. Periapical radiographs were evaluated immediately after implant placement (baseline), 6 months, and at the most recent follow-up. MBL was calculated from the difference between initial and final measurements, taking into account a distortion rate for each radiograph compared with original implant measurements. RESULTS Survival rate was 98.2%, with only one implant lost (100% survival rate after loading) over a mean follow-up time of 2.0 ± 0.9 years. MBL ranged from 0 to 2.85 mm: 75.9% of mesial sites and 83.4% of distal sites showed <1 mm of MBL, whereas 35.2% of mesial sites and 37% of distal sites exhibited no bone loss. MBL was significantly (P <0.05) greater in open-flap compared with flapless surgery. CONCLUSIONS Within the limitations of the present study, it was concluded that maxillary sinus elevation with 100% ABB gives predictable results, and that flapless surgery results in less MBL compared with traditional open-flap surgery.
Use of varenicline for more than 12 months for smoking cessation in heavy chronic obstructive pulmonary disease smokers unmotivated to quit: a pilot study

Introduction: Use of varenicline for as long as necessary to achieve abstinence has not been studied. The aim of this study was to test whether smokers with mild-to-moderate chronic obstructive pulmonary disease (COPD) are able to quit if they use varenicline for a sufficient length of time. Methods: A total of 30 heavy smokers with COPD took varenicline for sufficiently long enough for smoking cessation. Smokers were allowed to smoke without a fixed quit date. The main endpoints were the time of voluntary abstinence (VA) and the continuous abstinence rate (CAR) at 12 and 18 months. Results: Of 28 subjects, eight subjects continued to smoke and 20 subjects stopped smoking, demonstrating a CAR up to 18 months (71%). Median time of treatment was 6 (range 3–24) and 2 (range 1–8) months for abstainers and non-abstainers, respectively, and the median time of VA for abstainers was 4 (range 1–21) months. Conclusions: Use of varenicline for more than the traditional 12 recommended weeks may be a good strategy to increase the cessation rate in heavy smokers with mild COPD.
Serum BDNF Is Positively Associated With Negative Symptoms in Older Adults With Schizophrenia

Objectives: Older adults with chronic schizophrenia are at greater risk for functional disability and poorer health outcomes than those without serious mental illness. These individuals comprise 1–2% of the elderly population in the United States and are projected to number approximately 15 million by 2030. The symptoms of schizophrenia can be disabling for individuals, significantly reducing quality of life. Often, the negative symptoms (NS) are the most resistant to treatment and are considered a marker of illness severity, though they are challenging to measure objectively. Biomarkers can serve as objective indicators of health status. Brain-derived neurotrophic factor (BDNF) is a potential biomarker for schizophrenia and may serve as an important indicator of illness severity. Methods: A cross-sectional study with 30 older adults with chronic schizophrenia. Participants were assessed on serum levels of BDNF and psychiatric symptoms (Positive and Negative Syndrome Scale). Pearson’s bivariate correlations (two-tailed) and linear regression models were used. Results: A significant positive association (p < .05) was found between higher serum levels of BDNF and greater severity for the NS items of passive, apathetic, social withdrawal, and emotional withdrawal. In multivariate analyses, the association remained significant. Conclusions: Although the association between BDNF and NS was not in the expected direction, the data corroborate findings from previous work in patients with schizophrenia. It is possible that higher serum levels of BDNF reflect compensatory neuronal mechanisms resulting from neurodevelopmental dysfunction.
Apical Involvement With Fibrous Dysplasia: Implications for Vision

Purpose: To describe the ophthalmic findings of fibrous dysplasia of the orbit. Methods: Prospective case series. Twenty-one patients with fibrous dysplasia with orbital involvement underwent a complete ophthalmic examination and orbital imaging by CT. Results: Four of the 21 patients had McCune–Albright syndrome and 1 had tuberous sclerosis. In 17 patients (81%), the disease was restricted to the craniofacial region. Facial distortion, proptosis, and eye dystopia were detected in 62% of the patients. Nasolacrimal duct obstruction and strabismus were detected in only 1 and 2 patients, respectively. Of the 34 orbits affected, the roof was affected in 67.6%. The floor was the least affected wall. For most orbits, the disease was seen in more than 1 wall, and in 9 orbits (26.5%) all 4 walls were involved. Twelve orbits (35.2%) showed cysts on CT within the affected bones. In 19 orbits (55.9%), the optic canal was circumferentially narrowed. Blindness was detected in only 1 patient who had undergone optic canal decompression. Conclusions: The main consequences of orbital involvement in fibrous dysplasia are eye dystopia and proptosis. Apical involvement is a common feature. Optic canal narrowing does not necessarily induce vision loss. We believe that patients with apical involvement should be carefully followed and have their apices decompressed only when their vision is clearly deteriorating. Our data do not support prophylactic optic canal decompression as a therapeutic measure.
Speech Understanding in Complex Listening Environments by Listeners Fit With Cochlear Implants.

Purpose The aim of this article is to summarize recent published and unpublished research from our 2 laboratories on improving speech understanding in complex listening environments by listeners fit with cochlear implants (CIs). Method CI listeners were tested in 2 listening environments. One was a simulation of a restaurant with multiple, diffuse noise sources, and the other was a cocktail party with 2 spatially separated point sources of competing speech. At issue was the value of the following sources of information, or interventions, on speech understanding: (a) visual information, (b) adaptive beamformer microphones and remote microphones, (c) bimodal fittings, that is, a CI and contralateral low-frequency acoustic hearing, (d) hearing preservation fittings, that is, a CI with preserved low-frequency acoustic in the same ear plus low-frequency acoustic hearing in the contralateral ear, and (e) bilateral CIs. Results A remote microphone provided the largest improvement in speech understanding. Visual information and adaptive beamformers ranked next, while bimodal fittings, bilateral fittings, and hearing preservation provided significant but less benefit than the other interventions or sources of information. Only bilateral CIs allowed listeners high levels of speech understanding when signals were roved over the frontal plane. Conclusions The evidence supports the use of bilateral CIs and hearing preservation surgery for best speech understanding in complex environments. These fittings, when combined with visual information and microphone technology, should lead to high levels of speech understanding by CI patients in complex listening environments.

Older women public sector workers in Ireland: Decisions about retirement timing

ABSTRACT Older women workers’ decision making around retirement is increasingly important given the increasing involvement of older women in paid employment. This article explores influences on the retirement decision making of older women workers in Ireland. It is based on a case study of 57 interviews with women in the Irish civil service exploring work-life decision making. It finds that retirement choices vary according to initial socioeconomic resources and/or life-course trajectories and are particularly affected by gendered caring norms, employment policy, job tenure, and place in organizational hierarchies. Those women with interrupted careers and low pay have fewer choices around retirement timing.
PiCode: A New Picture-Embedding 2D Barcode

Nowadays, 2D barcodes have been widely used as an interface to connect potential customers and advertisement contents. However, the appearance of a conventional 2D barcode pattern is often too obtrusive for integrating into an aesthetically designed advertisement. Besides, no human readable information is provided before the barcode is successfully decoded. This paper proposes a new picture-embedding 2D barcode, called PiCode, which mitigates these two limitations by equipping a scannable 2D barcode with a picturesque appearance. PiCode is designed with careful considerations on both the perceptual quality of the embedded image and the decoding robustness of the encoded message. Comparisons with the existing beautified 2D barcodes show that PiCode achieves one of the best perceptual qualities for the embedded image, and maintains a better tradeoff between image quality and decoding robustness in various application conditions. PiCode has been implemented in the MATLAB on a PC and some key building blocks have also been ported to Android and iOS platforms. Its practicality for real-world applications has been successfully demonstrated.
Central retinal preservation in rdAc cats

OBJECTIVE Children with Leber congenital amaurosis (LCA) due to CEP290 mutations show characteristic macular preservation. Spectral domain-optical coherence tomography (SD-OCT) is a noninvasive technique to investigate retinal structural changes. Loss of integrity of the ellipsoid zone (EZ) on OCT in people with retinal disease has been associated with loss of visual function and is a useful measure of retinal disease progression. We hypothesized that rdAc felines with Cep290 mutation would have a similar pattern of degeneration, with relative central retinal preservation associated with maintenance of the EZ. PROCEDURES Fundus imaging, confocal scanning laser ophthalmoscopy, and SD-OCT cross-sectional imaging was performed on 11 rdAc cats ranging from 6 months to 10 years of age. Images were collected from the area centralis, visual streak, and the mid-superior and mid-inferior retina. Receptor plus (REC+, encompassing the entire length of photoreceptors) thicknesses were measured. Regional rates of degeneration were determined by regression analysis and compared using unpaired t-tests. The EZ was evaluated for the presence, absence, or loss of definition. RESULTS RdAc cats showed REC+ thinning over time in all regions. The area centralis and visual streak had a slower rate of thinning than the mid-peripheral retina. There was loss of integrity of the EZ initially in the more peripheral regions, while its integrity was maintained in the area centralis and visual streak at all ages studied. CONCLUSIONS rdAc cats show preservation of the central retina with maintenance of EZ integrity, which recapitulates findings in human patients.
Drought stress and tree size determine stem CO 2 efflux in a tropical forest

Summary CO 2 efflux from stems (CO 2_stem) accounts for a substantial fraction of tropical forest gross primary productivity, but the climate sensitivity of this flux remains poorly understood. We present a study of tropical forest CO 2_stem from 215 trees across wet and dry seasons, at the world's longest running tropical forest drought experiment site. We show a 27% increase in wet season CO 2_stem in the droughted forest relative to a control forest. This was driven by increasing CO 2_stem in trees 10–40 cm diameter. Furthermore, we show that drought increases the proportion of maintenance to growth respiration in trees > 20 cm diameter, including large increases in maintenance respiration in the largest droughted trees, > 40 cm diameter. However, we found no clear taxonomic influence on CO 2_stem and were unable to accurately predict how drought sensitivity altered ecosystem scale CO 2_stem, due to substantial uncertainty introduced by contrasting methods previously employed to scale CO 2_stem fluxes. Our findings indicate that under future scenarios of elevated drought, increases in CO 2_stem may augment carbon losses, weakening or potentially reversing the tropical forest carbon sink. However, due to substantial uncertainties in scaling CO 2_stem fluxes, stand‐scale future estimates of changes in stem CO 2 emissions remain highly uncertain.
A dynamic bioenergetic model for coral-Symbiodinium symbioses and coral bleaching as an alternate stable state

Coral reef ecosystems owe their ecological success–and vulnerability to climate change–to the symbiotic metabolism of corals and Symbiodinium spp. The urgency to understand and predict the stability and breakdown of these symbioses (i.e., coral ‘bleaching’) demands the development and application of theoretical tools. Here, we develop a dynamic bioenergetic model of coral-Symbiodinium symbioses that demonstrates realistic steady-state patterns in coral growth and symbiont abundance across gradients of light, nutrients, and feeding. Furthermore, by including a mechanistic treatment of photo-oxidative stress, the model displays dynamics of bleaching and recovery that can be explained as transitions between alternate stable states. These dynamics reveal that ‘healthy’ and ‘bleached’ states correspond broadly to nitrogen- and carbon-limitation in the system, with transitions between them occurring as integrated responses to multiple environmental factors. Indeed, a suite of complex emergent behaviors reproduced by the model (e.g., bleaching is exacerbated by nutrients and attenuated by feeding) suggests it captures many important attributes of the system; meanwhile, its modular framework and open source R code are designed to facilitate further problem-specific development. We see significant potential for this modeling framework to generate testable hypotheses and predict integrated, mechanistic responses of corals to environmental change, with important implications for understanding the performance and maintenance of symbiotic systems.
