Unintended consequences: the negative impact of e-mail use on participation and collective identity in two ‘horizontal’ social movement groups

The relation between face-to-face and online communication and its impact on collective identity processes is understudied. In this article I draw on two case studies conducted during a 3-year ethnographic study of the Global Justice Movement network in Madrid, Spain, from 2002 to 2005 to explore the unintended impact of e-mail on the sustainability, internal dynamics, and collective identity of two groups committed to participatory and deliberative practices as key features of their collective identity. I found that despite an explicit commitment to ‘horizontalism’ the use of e-mail in these two groups increased existing hierarchies, hindered consensus, decreased participation, and worked towards marginalization of group members. In addition, the negative and unintended consequences of e-mail use affected both groups, independently of activists’ evaluation of their experience in their face-to-face assemblies (one of which was overwhelmingly perceived as positive and one of which was perceived as negative). The article draws on e-mail research in organizations, online political deliberation research, and existing studies of e-mail use in social movement groups to analyse these findings.
A RANDOMIZED , DOUBLE-BLIND STUDY EXAMINING THE COMPARATIVE EFFICACIES AND SAFETY OF INHALED EPINEPHRINE AND NASAL DECONGESTANT IN HOSPITALIZED INFANTS WITH ACUTE BRONCHIOLITIS

Optimal treatment of acute bronchiolitis is currently unclear. In a double-blind study, we found no significant differences between inhaled epinephrine and nasal decongestant in hospitalized infants with acute bronchiolitis regarding length of hospitalization, need for oxygen supplementation, or intravenous fluids and clinical score. Nasal decongestant is as effective as inhaled epinephrine in acute bronchiolitis.
A Data Driven Neural Network Approach to Optimal Asset Allocation for Target Based Defined Contribution Pension Plans

Abstract A data-driven Neural Network (NN) optimization framework is proposed to determine optimal asset allocation during the accumulation phase of a defined contribution pension scheme. In contrast to parametric model based solutions computed by a partial differential equation approach, the proposed computational framework can scale to high dimensional multi-asset problems. More importantly, the proposed approach can determine the optimal NN control directly from market returns, without assuming a particular parametric model for the return process. We validate the proposed NN learning solution by comparing the NN control to the optimal control determined by solution of the Hamilton–Jacobi–Bellman (HJB) equation. The HJB equation solution is based on a double exponential jump model calibrated to the historical market data. The NN control achieves nearly optimal performance. An alternative data-driven approach (without the need of a parametric model) is based on using the historic bootstrap resampling data sets. Robustness is checked by training with a blocksize different from the test data. In both two and three asset cases, we compare performance of the NN controls directly learned from the market return sample paths and demonstrate that they always significantly outperform constant proportion strategies.
Bayesian Chronological Modeling of SunWatch, a Fort Ancient Village in Dayton, Ohio

Radiocarbon results from houses, pits, and burials at the SunWatch site, Dayton, Ohio, are presented within an interpretative Bayesian statistical framework. The primary model incorporates dates from archaeological features in an unordered phase and uses charcoal outlier modeling (Bronk Ramsey 2009b) to account for issues of wood charcoal 14C dates predating their context. The results of the primary model estimate occupation lasted for 1–245 yr (95% probability), starting in cal AD 1175–1385 (95% probability) and ending in cal AD 1330–1470 (95% probability). An alternative model was created by placing the 14C dates into two unordered phases corresponding with horizontal stratigraphic relationships or distinct groups of artifacts thought to be temporally diagnostic. The results of the alternative model further suggest that there is some temporal separation between Group 1 and Group 2, which seems more likely in the event of a multicomponent occupation. Overall, the modeling results provide chronology estimates for SunWatch that are more accurate and precise than that provided in earlier studies. While it is difficult to determine with certainty if SunWatch had a single-component or multicomponent occupation, it is clear that SunWatch's occupation lasted until the second half of the AD 1300s.
Evaluation of the proliferative activity of immunocompetent cells in the jejunal and iliac lymph nodes of prepubertal female wild boars diagnosed with mixed mycotoxicosis

Abstract The study evaluated the proliferative activity of immunocompetent cells in the jejunal and iliac lymph nodes of prepubertal female wild boars exposed to deoxynivalenol and zearalenone in naturally contaminated feed. The evaluation was performed with the use of the MTT assay and 2 mitogens: lipopolysaccharide (LPS) and concanavalin A. Intensified proliferative processes in T and B lymphocytes were revealed. The mitogenic activity of LPS was more expressed in the lymphocytes of both iliac and jejunal lymph nodes in comparison with the control group. Proliferative activity was higher in iliac lymph nodes than in jejunal lymph nodes. A reverse trend was observed in the percentage of live cells, which was higher in jejunal lymph nodes during the evaluation of lymphocyte proliferation.
MRI findings and physical performance as predictors of flight-induced musculoskeletal pain incidence among fighter pilots

Summary Study aim: The aim of this study was to evaluate the possible association of pre-career magnetic resonance imaging (MRI) findings and physical performance level with possible musculoskeletal disorders during jet flight training. Material and methods: The study group consisted of 73 fighter pilots who had undergone pre-career cervical and lumbar spine MRI. Physical performance of a subgroup of the pilots (n = 67) was measured initially at the same time and followed up to the fast jet training phase (ranging from 3.8 to 7.0 years). Musculoskeletal pain history during pilot training was taken from the medical charts. MRI findings and physical performance were associated with perceived clinical complaints during the follow-up. Results: 82% of the cervical and 92% of the lumbar spines showed abnormalities at at least one disk level. MRI did not reveal significant cervical degeneration. Thirteen disk bulges in the lumbar spine were discovered, while 5 pilots had listhesis and/or osteophyte formation on the spine (lumbar vertebra 4/sacroiliac joint level, L4-SI). 41% of the studied pilots suffered spinal symptoms during the follow-up, but only 16% and 17% of the cervical and lumbar MRI findings, respectively, were associated with subsequent symptoms. Endurance and strength levels were not, but lower body motor skills were, strongly (relative risk, RR 0.46) associated with a decreased number of flight-induced medical appointments in the early flight career. Conclusions: Minor MRI findings have no predictable value in the very early flight career. Nevertheless, versatile, skills/power-oriented exercises before the flight career seem to be occupationally beneficial in reducing musculoskeletal disorders.
Effects of day length on pollen tube elongation, embryo formation and seed development after flowering in quinoa (Chenopodium quinoa Willd.)

Abstract The objective of this study was to evaluate the effect of day length after flowering on pollen tube elongation, embryo formation and seed development. The quinoa varieties used in this study were Amarilla de Marangani (valley type) and NL-6 (sea-level type). After sowing, the quinoa plants were cultivated in growth cabinets. From sowing to flowering, plants were exposed to a 15 h day length regime. After flowering, the plants were grown under either a 15 h or 11 h day length regime. The elongation of the pollen tube and the formation of the early embryo were not inhibited in either Amarilla de Marangani or NL-6 under the 11 or 15 h day length regimes. Although growth of the embryo in NL-6 was not inhibited by the 15 h day length regime after flowering, the same was not observed in the case for Amarilla de Marangani. In Amarilla de Marangani, seed diameter at 8 and 14 days after flowering under the 11 h day length regime was larger than that of seeds grown under the 15 h day length regime. Thus, the decrease in the number of seeds in Amarilla de Marangani grown under the 15 h day length regime may be caused by the suspension of embryo growth after fertilization.
Stacked Latent Attention for Multimodal Reasoning

Attention has shown to be a pivotal development in deep learning and has been used for a multitude of multimodal learning tasks such as visual question answering and image captioning. In this work, we pinpoint the potential limitations to the design of a traditional attention model. We identify that 1) current attention mechanisms discard the latent information from intermediate reasoning, losing the positional information already captured by the attention heatmaps and 2) stacked attention, a common way to improve spatial reasoning, may have suboptimal performance because of the vanishing gradient problem. We introduce a novel attention architecture to address these problems, in which all spatial configuration information contained in the intermediate reasoning process is retained in a pathway of convolutional layers. We show that this new attention leads to substantial improvements in multiple multimodal reasoning tasks, including achieving single model performance without using external knowledge comparable to the state-of-the-art on the VQA dataset, as well as clear gains for the image captioning task.
Human frontoparietal cortex represents behaviorally-relevant target status during invariant object recognition

Searching for items that are useful given current goals, or “target” recognition, requires an observer to generalize across identity-preserving transformations such as viewpoint changes, as well as to incorporate contextual information. While past work has found target recognition signals in areas of ventral visual cortex, it is not clear whether these signals support performance on demanding tasks that require invariant, flexible search. Here, we used a task that required subjects to match novel object stimuli based on invariant features (identity and viewpoint). Based on multivariate fMRI analyses, the data suggest that the multiple-demand (MD) network, including sub-regions of parietal and frontal cortex, encodes invariant representations of an object’s status as a target. Furthermore, target information in MD regions, but not early or ventral visual cortex, was higher on correct compared to incorrect trials, suggesting a strong link between MD target signals and behavior.

The effects of soil management practices on soil organic matter changes within a productive vineyard in the Nitra viticulture area (Slovakia)

Abstract Since understanding soil organic matter (SOM) content and quality is very important, in the present study we evaluated parameters of SOM including: carbon lability (LC), lability index (LI), carbon pool index (CPI) and carbon management index (CMI) in the soil as well as in the water-stable aggregates (WSA) under different soil management practices in a commercial vineyard (established on Rendzic Leptosol in the Nitra viticulture area, Slovakia). Soil samples were taken in spring during the years 2008–2015 from the following treatments: G (grass, control), T (tillage and intensive cultivation), T+FYM (tillage + farmyard manure), G+NPK3 (grass + 3rd intensity of fertilisation for vineyards), and G+NPK1 (grass + 1st intensity of fertilisation for vineyards). The highest LI values in soil were found for the G+NPK3 and T+FYM fertilised treatments and the lowest for the unfertilised intensively tilled treatments. The CPI in the soil increased as follows: T < G+NPK3 < T+FYM < G+NPK1. The highest accumulation of carbon as well as decomposable organic matter occurred in G+NPK1 compared to other fertilised treatments, while intensive tillage caused a decrease. On average, the values of LI in WSA increased in the sequence G+NPK1 < T+FYM < G+NPK3 < T. Our results showed that the greatest SOM vulnerability to degradation was observed in the WSA under T treatment, and the greatest values of CPI in WSA were detected as a result of fertiliser application in 3rd intensity for vineyards and farmyard manure application.
Culture of Carbapenemase-Producing Enterobacteriaceae in a Tertiary-Care Hospital

Background: Carbapenem-resistant Enterobacteriaceae (CRE) are increasingly being reported throughout the world, which is a significant problem for patient treatment and infection control. Carbapenem-resistance in Enterobacteriaceae is mainly due to carbapenemhydrolyzing β-lactamase, which tends to spread through genetic mobile elements. Therefore, the detection of carbapenemase-producing Enterobacteriaceae (CPE) carriers is particularly important for the prevention and epidemiological monitoring of these infections. In this study, we performed surveillance cultures for CPE in patients admitted to the hospital and evaluated the prevalence of CPE. Methods: Stool cultures were obtained from a total of 228 patients at our tertiary-care hospital between March and May 2017. Stool specimens were inoculated on ChromID CARBA agar (bioMérieux, France) and incubated for 18-24 hours. Suspicious colonies with pink or bluish-green color were screened for CPE by the modified Hodge test (MHT) and carbapenemase inhibition test (CIT). We performed PCR to detect five carbapenemase genes, blaKPC, blaIMP, blaVIM, blaNDM, and blaOXA-48. Results: Among 228 isolates, seven were suspicious for CPE: four Klebsiella pneumoniae, one Escherichia coli, one Enterobacter aerogenes, and one Serratia marcescens. Two K. pneumoniae isolates showed positive reactions in both the modified Hodge test and inhibition test with phenylboronic acid. By PCR, blaKPC was identified in these two K. pneumoniae isolates. Conclusion: Our results showed a very low prevalence (2/228, 0.9%) of CPE in our tertiary-care hospital based on surveillance culture in a recent three month period. (Ann Clin Microbiol 2018;21:8-11)
Agglomeration, accessibility and productivity: Evidence for large metropolitan areas in the US

This paper estimates the productivity gains from agglomeration economies for a sample of the largest metropolitan areas in the United States using measures of urban agglomeration based on employment density and employment accessibility. The latter is a more accurate measure of economic proximity and allows testing for the spatial decay of agglomeration effects with increasing travel time. We find that the productivity gains from urban agglomeration are consistent between measures, with elasticity values between 0.07 and 0.10. The large majority of the productivity gains occur within the first 20 minutes, and do not appear to exhibit significant nonlinearities.
Oil content and fatty acids composition of poppy seeds cultivated in two localities of Slovakia

Abstract Oil content, fatty acids profile, acid and saponification values of poppy seeds grown on two localities of the Slovak Republic were evaluated in the study. Statistically significant effects of locality, genotype and their interaction (P < 0.05) for numerous descriptors were proved by non-parametric tests. Results confirmed that variation in the analysed parameters was influenced by the colour of seeds. Ochre variety Redy contained the highest oil level in both localities (49.9 and 52.4%) and linoleic acid level (74.3 and 71.6%). White-seeded Racek and Albín had the highest acid value (2.8 and 2.4% of free fatty acids) and grey-seeded Malsar and blue-seeded Maratón contained the highest saponification value. Buddha, a high-morphine poppy variety, differed significantly in all monitored parameters. High negative interrelation between linoleic and oleic acids levels was observed. Oil content was positively correlated with linoleic acid and negatively with oleic acid. Weather conditions at the end of vegetation influenced the accumulation of oil and essential linoleic acid.
Antibody Microarray Expression Profiling Of Maize Roots Treated With Cadmium And Nickel

Abstract Here, we report the effectiveness of antibody microarray expression profiling (AbMEP) procedure to determine similarities and differences between two maize cultivars (Premia and Blitz) exposed to various concentration of cadmium (Cd), nickel (Ni), as well as simultaneous exposure to both metals (Cd + Ni) for 0, 12 and 24 h. After protein extraction from control (untreated) and heavy metals (HM)-treated root pairs and their fluorescent labelling, the protein extracts were used for the AbMEP procedure and western blot analysis. The results from the microarray were analysed using an internally normalised ratio. Using this highly parallel AbMEP-approach, the timing, dynamics and regulation of the expression of 101 specific genes in untreated and HM-treated roots of maize cultivars were determined. The microarray results revealed 23, 15 and 10 up-regulated/down-regulated proteins in Cd, Ni and Cd + Ni treated cv. Premia roots, respectively. In contrast, the microarray results revealed that 15, 11 and 7 proteins were up-regulated/down-regulated in Cd, Ni and Cd + Ni treated cv. Blitz roots, respectively. The data obtained from the AbMEP array experiment were validated by western blot analyses with more than 89% (the Pearson’s correlation coeficient Rr = 0.78) correlation between the two methods.
Grazing by Karenia brevis on Synechococcus enhances its growth rate and may help to sustain blooms

Grazing rates of Karenia brevis Clones CCMP2228 and CCMP2229 were determined in laboratory experiments using Synechococcus sp. Clone CCMP1768 as food. Growth (days to weeks) and uptake rates (hours to days) were assessed. In the growth experiments, K. brevis, previously depleted in nitrogen (N), was grown at 2 light intensities in the presence of varying concentrations of Synechococcus. Under high irradiance (300 µmol photons m -2 s -1 ; 14 h light:10 h dark cycle), expo- nential growth rates approximated those of phototrophic growth without Synechococcus (0.26 to 0.35 d -1 ). At this irradiance, K. brevis cells in all treatments grew for about 10 d. Under lower irradi- ance (43 µmol photons m -2 s -1 ), exponential growth rates of K. brevis cells varied with the enrichment level of Synechococcus, with rates under the highest Synechococcus enrichment level being nearly twice (0.58 d -1 ) those observed for the high irradiance treatments. Short-term uptake experiments (3 experiments, 2 clones) were done to examine the N-specific rates of grazing of 15 N-labeled Syne- chococcus. N-specific rates of grazing ranged from 9.28 × 10 -4 h -1 to 1.22 × 10 -2 h -1 and varied with the relative proportion of Synechococcus:K. brevis. These rates represent a range of 0.026 to 2.15 pmol-N K. brevis -1 d -1 , or 0.96 to 83.8 Synechococcus K. brevis -1 h -1 . Evidence of Synechococcus inside K. brevis was provided by confocal microscopy. Grazing by K. brevis thus enhances the range of nutritional substrates available to meet its growth requirements, and may play a substantial role in sustaining natural populations in inorganic N-poor waters.
Running head : INTERNALIZING / EXTERNALIZING SEX DIFFERENCES IN ASD Sex Differences in Internalizing and Externalizing Behaviors in Children with Autism Spectrum Disorder

This study used a retrospective practice-based research method to compare levels of internalizing and externalizing behaviors of a clinically-ascertained sample of young children with autism spectrum disorder (ASD; n=90). As measured by the Child Behavior Checklist (CBCL), internalizing and externalizing behaviors were compared to normative behavior, and between boys and girls with ASD. Findings suggest that in a clinical sample, children with ASD are more likely than typically developing children to have internalizing and/or externalizing problems. No significant sex differences were found for Internalizing Problems, Externalizing Problems, or Total Problems scores on either the parent or teacher versions of the CBCL. These findings may help clinicians better understand how children with ASD are affected by co-morbid psychiatric disorders, and could help to inform diagnosis and intervention.
Does Flight Path Context Matter? Impact on Worker Performance in Crowdsourced Aerial Imagery Analysis

Natural disasters result in billions of dollars in damages annually and communities left struggling with the difficult task of response and recovery. To this end, small private aircraft and drones have been deployed to gather images along flight paths over the affected areas, for analyzing aerial photography through crowdsourcing. However, due to the volume of raw data, the context and order of these images is often lost when reaching workers. In this work, we explored the effect of contextualizing a labeling task on Amazon Mechanical Turk, by serving workers images in the order they were collected on the flight and showing them the location of the current image on a map. We did not find a negative impact from the loss of contextual information, and found map context had a negative impact on worker performance. This may indicate that ordering images based on other criteria may be more effective.
Habitat-specific seed dormancy-release mechanisms in four legume species

Abstract Physical seed dormancy is a common attribute among plants, and a wide range of dormancy-release mechanisms have been described, but their ecological significance is rarely tested through comparative study. This study tests whether dormancy-release responses to wet heat in four legume species with physical dormancy are correlated with habitat: two wetland species (Mimosa pigra and Parkinsonia aculeata, both dispersed primarily by water) and two terrestrial species (Acacia nilotica and Prosopis pallida, both dispersed primarily through vertebrate herbivores). Dormancy release was compared at three moisture levels (80% relative humidity, saturated and submerged) at constant (20–45°C) and diurnally fluctuating (20/40°C) temperatures for 14 d. Seed viability was tested by germinating at 25°C. The functional relationship between temperature and dormancy release after 14 d differed between species: submerged seeds of the two wetland species showed a quadratic response, with low rates of imbibition below 20–25°C and complete imbibition at around 40°C; P. pallida seeds showed a linear positive relationship, whereas there was no temperature response for A. nilotica seeds below 45°C. Surprisingly, dormancy release after 14 d was relatively insensitive to moisture levels, although rate of dormancy release was generally slower under drier conditions. Dormancy release was not influenced by fluctuating temperatures. Seed viability was largely unaffected by temperature or moisture regime, although it did differ with species and was lower for non-dormant seeds. Our results suggest that a functional dormancy-release response to wet heat provides important fitness benefits for wetland species, but not for species dispersed through vertebrate herbivores, for which it may be maladaptive.
