Transforming communicative spaces: the rhythm of gender in meetings in rural Solomon Islands

Women's lack of participation in important decision making is noted as an obstacle to sustainable development in many parts of the world. An initial issue for gender equity in environmental decision making in many developing country contexts is not only women's inclusion but also their substantive participation in decision-making forums. In this article I examine the power structures embedded in the public communicative spaces in a village in the Western Province of Solomon Islands using empirical data in conjunction with ethnographic understanding of gendered meeting styles. The data reveal some reasons why women may be silenced as public political actors. It also raises the potential for development actors to create conceptual space for specific women's ways of meeting and validating women's meeting styles. These findings have implications for encouraging transformative communicative spaces and formats that allow transcendence of socially embedded power structures

Reading Performance is Predicted by More Than Phonological Processing

We compared three phonological processing components (phonological awareness, rapid automatized naming and phonological memory), verbal working memory, and attention control in terms of how well they predict the various aspects of reading: word recognition, pseudoword decoding, fluency and comprehension, in a mixed sample of 182 children ages 8–12 years. Participants displayed a wide range of reading ability and attention control. Multiple regression was used to determine how well the phonological processing components, verbal working memory, and attention control predict reading performance. All equations were highly significant. Phonological memory predicted word identification and decoding. In addition, phonological awareness and rapid automatized naming predicted every aspect of reading assessed, supporting the notion that phonological processing is a core contributor to reading ability. Nonetheless, phonological processing was not the only predictor of reading performance. Verbal working memory predicted fluency, decoding and comprehension, and attention control predicted fluency. Based upon our results, when using Baddeley’s model of working memory it appears that the phonological loop contributes to basic reading ability, whereas the central executive contributes to fluency and comprehension, along with decoding. Attention control was of interest as some children with ADHD have poor reading ability even if it is not sufficiently impaired to warrant diagnosis. Our finding that attention control predicts reading fluency is consistent with prior research which showed sustained attention plays a role in fluency. Taken together, our results suggest that reading is a highly complex skill that entails more than phonological processing to perform well

The Quantitative-MFG Test: A linear mixed effect model to detect maternal-offspring gene interactions

Maternal-offspring gene interactions, aka maternal-fetal genotype (MFG) incompatibilities, are neglected in complex diseases and quantitative trait studies. They are implicated in birth to adult onset diseases but there are limited ways to investigate their influence on quantitative traits. We present the Quantitative-MFG (QMFG) test, a linear mixed model where maternal and offspring genotypes are fixed effects and residual correlations between family members are random effects. The QMFG handles families of any size, common or general scenarios of MFG incompatibility, and additional covariates. We develop likelihood ratio tests (LRTs) and rapid score tests and show they provide correct inference. In addition, the LRT’s alternative model provides unbiased parameter estimates. We show that testing the association of SNPs by fitting a standard model, which only considers the offspring genotypes, has very low power or can lead to incorrect conclusions. We also show that offspring genetic effects are missed if the MFG modeling assumptions are too restrictive. With GWAS data from the San Antonio Family Heart Study, we demonstrate that the QMFG score test is an effective and rapid screening tool. The QMFG test therefore has important potential to identify pathways of complex diseases for which the genetic etiology remains to be discovered

Visual Processing in Reading Disorders and Attention-Deficit/Hyperactivity Disorder and Its Contribution to Basic Reading Ability

Whether visual processing deficits are common in reading disorders (RD), and related to reading ability in general, has been debated for decades. The type of visual processing affected also is debated, although visual discrimination and short-term memory (STM) may be more commonly related to reading ability. Reading disorders are frequently comorbid with ADHD, and children with ADHD often have subclinical reading problems. Hence, children with ADHD were used as a comparison group in this study. ADHD and RD may be dissociated in terms of visual processing. Whereas RD may be associated with deficits in visual discrimination and short-term memory for order, ADHD is associated with deficits in visual-spatial processing. Thus, we hypothesized that children with RD would perform worse than controls and children with ADHD only on a measure of visual discrimination and a measure of visual STM that requires memory for order. We expected all groups would perform comparably on the measure of visual STM that does not require sequential processing. We found children with RD or ADHD were commensurate to controls on measures of visual discrimination and visual STM that do not require sequential processing. In contrast, both RD groups (RD, RD/ADHD) performed worse than controls on the measure of visual STM that requires memory for order, and children with comorbid RD/ADHD performed worse than those with ADHD. In addition, of the three visual measures, only sequential visual STM predicted reading ability. Hence, our findings suggest there is a deficit in visual sequential STM that is specific to RD and is related to basic reading ability. The source of this deficit is worthy of further research, but it may include both reduced memory for order and poorer verbal mediation

Shrink film patterning by craft cutter: complete plastic chips with high resolution/high-aspect ratio channel

This paper presents a rapid, ultra-low-cost approach to fabricate microfluidic devices using a polyolefin shrink film and a digital craft cutter. The shrinking process (with a 95% reduction in area) results in relatively uniform and consistent microfluidic channels with smooth surfaces, vertical sidewalls, and high aspect ratio channels with lateral resolutions well beyond the tool used to cut them. The thermal bonding of the layers results in strongly bonded devices. Complex microfluidic designs are easily designed on the fly and protein assays are also readily integrated into the device. Full device characterization including channel consistency, optical properties, and bonding strength are assessed in this technical note

Transformative spaces in the making: key lessons from nine cases in the Global South

Creating a just and sustainable planet will require not only small changes, but also systemic transformations in how humans relate to the planet and to each other, i.e., social–ecological transformations. We suggest there is a need for collaborative environments where experimentation with new configurations of social–ecological systems can occur, and we refer to these as transformative spaces. In this paper, we seek a better understanding of how to design and enable the creation of transformative spaces in a development context. We analyse nine case studies from a previous special issue on Designing Transformative Spaces that aimed to collect examples of cutting-edge action-oriented research on transformations from the Global South. The analysis showed five design phases as being essential: Problem Definition Phase; Operationalisation Phase; Tactical Phase; Outcome Phase; and Reflection Phase. From this synthesis, we distilled five key messages that should be considered when designing research, including: (a) there are ethical dilemmas associated with creating a transformative space in a system; (b) it is important to assess the readiness of the system for change before engaging in it; (c) there is a need to balance between ‘safe’ and ‘safe-enough’ spaces for transformation; (d) convening a transformative space requires an assemblage of diverse methodological frameworks and tools; and (e) transformative spaces can act as a starting point for institutionalising transformative change. Many researchers are now engaging in transdisciplinary transformations research, and are finding themselves at the knowledge–action interface contributing to transformative space-making. We hope that by analysing experiences from across different geographies we can contribute towards better understanding of how to navigate the processes needed for the urgent global transformations that are being called for to create a more equitable and sustainable planet Earth

Online Patient Portals: If You Build It, Who Will Come?

Research Objective: Many primary care practices have purchased electronic health records (EHRs) and accompanying patient portals. The role online portals may play in quality and outcome improvement will depend not only on who is using such technology, but how it is used. We evaluate the characteristics of patients using an online portal in comparison to those not using, and examine the portal features and functionalities accessed by users.Study Design: Observational, cohort study for which data were obtained from EHR and health system administrative data. Patient-level data (including demographic information, service use, and portal activation and use) were joined with information characterizing clinics in which patients received care (e.g., medical teaching on site, size, and urban/suburban location). The primary study outcome, portal use, was defined by the initiation of at least one online session. Among users, user-initiated clicks were used to determine specific features accessed. Logistic regression models with random effects were fit using the PROC GLIMMIX procedure (SAS software, Version 9.4) to test the role of clinic- and patient-level variables on patient portal activation. Subjects were blocked by physician, nested within clinic, and the Laplace method was used for likelihood approximation.Population Studied: Study eligible patients were aged 18 years and older with an office visit between 4/1/2013 and 3/31/2014 to a primary care physician practicing in one of the 26 primary care clinics of an integrated delivery system serving Detroit, Michigan and the surrounding suburban areas (N=20,282 patients).Principal Findings: As implemented in December 2012, the online portal enabled users to securely schedule appointments, receive appointment reminders, pay bills online, view lab and other test results, manage information about their health, and communicate with care teams via a secure messaging system. Cohort patients were on average 68.7 years of age (SD=14.7), predominately white (65%) or black (30%) race, and 60% female. Within 18 months of implementation, 33% had an activated account, with African Americans (OR=0.50, 95% CI 0.46-0.56), Hispanics (OR=0.63, 95% CI 0.47-0.84), those over aged 70 years (OR=0.48, 95% CI 0.44-0.52), and those preferring a language other than English (OR=0.43, 95% CI 0.31-0.59) less likely to be a portal user. Patients who were married (OR=0.55, 95% CI 1.44-1.67) and more connected with the clinic, as measured by visit frequency and health maintenance visit use, were more likely to be portal users (OR=1.08, 95% CI 1.05-1.10 and OR=1.39, 95% CI 1.27-1.52, respectively). Among users, the medical record access and management feature (95.9%) was most commonly accessed, most often to obtain laboratory testing results (91.7%). The majority of users also accessed appointment management (76.6%) and messaging (59.1%) functionalitiesConclusions: While the diversity of functions accessed by those with a portal account bodes well for the ability of portals to engage patients, without purposeful intervention enhancements to care delivery afforded by portals may be inaccessible to many, including racial/ethnic minorities and those less connected to traditional care services.Implications for Policy or Practice: Online portals have the potential to extend care beyond the confines of traditional office visits, but inattention to who uses portals may exacerbate known disparities in health care access and outcomes

First observations of Weddell seals foraging in sponges in Erebus Bay, Antarctica

Attaching cameras to marine mammals allows for first-hand observation of underwater behaviours that may otherwise go unseen. While studying the foraging behaviour of 26 lactating Weddell seals (Leptonychotes weddellii) in Erebus Bay during the austral spring of 2018 and 2019, we witnessed three adults and one pup investigating the cavities of Rossellidae glass sponges, with one seal visibly chewing when she removed her head from the sponge. To our knowledge, this is the first report of such behaviour. While the prey item was not identifiable, some Trematomus fish (a known Weddell seal prey) use glass sponges for shelter and in which to lay their eggs. Three of the four sponge foraging observations occurred around 13:00 (NZDT). Two of the three sponge foraging adults had higher-than-average reproductive rates, and the greatest number of previous pups of any seal in our study population, each having ten pups in 12 years. This is far higher than the study population average of three previous pups (± 2.6 SD). This novel foraging strategy may have evolved in response to changes in prey availability, and could offer an evolutionary advantage to some individuals that exploit prey resources that others may not. Our observations offer new insight into the foraging behaviours of one of the world’s most studied marine mammals. Further research on the social aspects of Weddell seal behaviour may increase our understanding of the extent and mechanisms of behavioural transfer between conspecifics. Research into the specific foraging behaviour of especially successful or experienced breeders is also warranted
