A study of infrasonic anisotropy and multipathing in the atmosphere using seismic networks

We discuss the use of reverse time migration (RTM) with dense seismic networks for the detection and location of sources of atmospheric infrasound. Seismometers measure the response of the Earth's surface to infrasound through acoustic-to-seismic coupling. RTM has recently been applied to data from the USArray network to create a catalogue of infrasonic sources in the western US. Specifically, several hundred sources were detected in 2007–2008, many of which were not observed by regional infrasonic arrays. The influence of the east–west stratospheric zonal winds is clearly seen in the seismic data with most detections made downwind of the source. We study this large-scale anisotropy of infrasonic propagation, using a winter and summer source in Idaho. The bandpass-filtered (1–5 Hz) seismic waveforms reveal in detail the two-dimensional spread of the infrasonic wavefield across the Earth's surface within approximately 800 km of the source. Using three-dimensional ray tracing, we find that the stratospheric winds above 30 km altitude in the ground-to-space (G2S) atmospheric model explain well the observed anisotropy pattern. We also analyse infrasound from well-constrained explosions in northern Utah with a denser IRIS PASSCAL seismic network. The standard G2S model correctly predicts the anisotropy of the stratospheric duct, but it incorrectly predicts the dimensions of the shadow zones in the downwind direction. We show that the inclusion of finer-scale structure owing to internal gravity waves infills the shadow zones and predicts the observed time durations of the signals. From the success of this method in predicting the observations, we propose that multipathing owing to fine scale, layer-cake structure is the primary mechanism governing propagation for frequencies above approximately 1 Hz and infer that stochastic approaches incorporating internal gravity waves are a useful improvement to the standard G2S model for infrasonic propagation modelling.
Role of Fusobacterium nucleatum and Coaggregation in Anaerobe Survival in Planktonic and Biofilm Oral Microbial Communities during Aeration

ABSTRACT Coaggregation is a well-characterized phenomenon by which specific pairs of oral bacteria interact physically. The aim of this study was to examine the patterns of coaggregation between obligately anaerobic and oxygen-tolerant species that coexist in a model oral microbial community. Obligate anaerobes other than Fusobacterium nucleatum coaggregated only poorly with oxygen-tolerant species. In contrast, F. nucleatum was able to coaggregate not only with both oxygen-tolerant and other obligately anaerobic species but also with otherwise-noncoaggregating obligate anaerobe–oxygen-tolerant species pairs. The effects of the presence or absence of F. nucleatum on anaerobe survival in both the biofilm and planktonic phases of a complex community of oral bacteria grown in an aerated (gas phase, 200 ml of 5% CO2 in air · min−1) chemostat system were then investigated. In the presence of F. nucleatum, anaerobes persisted in high numbers (>107 · ml−1 in the planktonic phase and >107 · cm−2 in 4-day biofilms). In an equivalent culture in the absence of F. nucleatum, the numbers of black-pigmented anaerobes (Porphyromonas gingivalis and Prevotella nigrescens) were significantly reduced (P ≤ 0.001) in both the planktonic phase and in 4-day biofilms, while the numbers of facultatively anaerobic bacteria increased in these communities. Coaggregation-mediated interactions between F. nucleatum and other species facilitated the survival of obligate anaerobes in aerated environments.
DISCUSSION AS AN ACTIVE LEARNING IN EFL

This paper brings in focus the importance of using discussion in EFL. Being an international language, English plays an important and crucial role in many people’s life. It is used for different purposes in social, education and social life of people. For this reason, English language students try to acquire, use and master it as much as possible to be effective speakers. English language teachers should provide students to frequently interactive activities in their classrooms. Students feel secure, motivated and willingly participate. In student -centered classes language is primarily a tool of communication. Communication implies interaction and this is done through speaking and interacting with each other. Communication and a supportive atmosphere in our English classes are essential for students’ acquisition. The success of this depends on teacher’s skill. Good teaching requires an understanding of both individual and group methods. Teacher’s goals are to support and give the opportunity to promote speaking through free expression of ideas and thinking. English language students at university sometimes find themselves better in cooperating rather than individual work. Using group and discussion methods promote speaking, language acquisition and an active learning.
Affective and Conative Factors as Aptitude Resources in High School Science Achievement

This article examines the role of affect and conation in high school students' science test performance. It provides a profile of partial correlations of standardized multiple-choice and constructed response test scores with affect and conation scores (after accounting for general ability and student background) at 3 distinct levels of generality: domain-specific, task-general, and situation-specific. Results show differential patterns of correlations, varying with level of generality of affective and conative constructs, and with different aspects of science achievement represented by the dimensions of basic knowledge and reasoning, quantitative science reasoning, and spatial-mechanical reasoning. The discussion invokes several theoretical frameworks to interpret these results. The article concludes by stressing the need for empirical and theoretical integration in the study of academic task performance.
Effects of the foot strike pattern on muscle activity and neuromuscular fatigue in downhill trail running

Minimizing musculo‐skeletal damage and fatigue is considered paramount for performance in trail running. Our purposes were to investigate the effects of the foot strike pattern and its variability on (a) muscle activity during a downhill trail run and (b) immediate and delayed neuromuscular fatigue. Twenty‐three runners performed a 6.5‐km run (1264 m of negative elevation change). Electromyographic activity of lower‐limb muscles was recorded continuously. Heel and metatarsal accelerations were recorded to identify the running technique. Peripheral and central fatigue was assessed in knee extensors (KE) and plantar flexors (PF) at Pre‐, Post‐, and 2 days post downhill run (Post2d). Anterior patterns were associated with (a) higher gastrocnemius lateralis activity and lower tibialis anterior and vastus lateralis activity during the run and (b) larger decreases in KE high‐frequency stimulus‐evoked torque Post and larger decrements in KE MVC Post2d. High patterns variability during the run was associated with (a) smaller decreases in KE Db100 Post and MVC Post2d and (b) smaller decreases in PF MVC Post and Post2d. Anterior patterns increase the severity of KE peripheral fatigue. However, high foot strike pattern variability during the run reduced acute and delayed neuromuscular fatigue in KE and PF.
The Cambridge Handbook of Personal Relationships: “His” and “Her” Relationships? A Review of the Empirical Evidence

Comparing the experiences of men and women in intimate relationships is a fascination some might say an obsession that has long intrigued laypeople and researchers alike. The public appears to crave information about how men and women differ in their approaches to love and relationships, a point reflected in the continuing popularity of John Gray's (1993) best-selling book, Men are from. Mars, Women are from Venus. Social scientists, too, have tackled this topic. Thirty years ago, sociologist Jessie Bernard (1972) proposed that in every marriage there are actually two relationships "his" and "hers. " In the intervening years, relationship researchers have energetically investigated the possibility of important gender differences in close relationships, extending their analyses beyond marriage to include cohabiting partners, gay and lesbian couples (see Diamond, this volume), and other intimate relationships. A comprehensive history of theory and research on gender in close relationships has yet to be written, but a few landmarks are illustrative. Early analyses, primarily by sociologists and anthropologists, focused on the family (see review by Glenn, 1987). Working from a functionalist perspective, theorists such as Parsons (1955) suggested that the existence of the traditional nuclear family provided evidence that differentiated male-female roles serve vital functions, including the socialization of children and the stabilization of adult personality. In the 19705, emerging feminist perspectives criticized prevailing theories as justifying the status quo. Instead, feminist scholars urged analyses of male-female relationships that considered gender ideology, power inequalities, the division of labor, and the social context (e.g., Bernard, 1972). Although feminists often argued for the social origins of traditional gender patterns in relationships, the development of sociobiology provided an alternative perspective rooted in human evolution. Symons' (1979) influential book, The Evolution of Human Sexuality, laid the groundwork for evolutionary analyses of mate selection, parental investment, and other topics that continue to be studied today. In the 19705, empirical projects such as the Boston Couples Study (e.g., Peplau, Hill, & Rubin, 1993) paid increasing
Measuring satisfaction in GSS meetings

Research suggests that group support systems (GSS) can enhance the performance of a team making a joint cognitive effort toward a goal. Yet, GSS are diffusing slowly. Dissatisfaction with electronic meetings may be one cause of this slow diffusion. If teams grow dissatisfied with GSS meetings, they may abandon the technology, even if it helps them to reach their goals. If they grow dissatisfied with the processes provided by the facilitator, they may abandon the facilitator’s interventions. Hence, meeting satisfaction is an important consideration when designing and fielding technology for teams.
Increasing Student Learning through Volitional Control

Students’ engagement and persistence on academic learning tasks often require their use of volitional strategies to protect against distractions and facilitate task completion. In this article we discusses factors that both positively and negatively influence students’ ability to regulate their learning activities and the supporting role that volitional strategies play in helping students to develop positive work habits for tackling academic assignments. Using the Academic Volitional Strategy Inventory (AVSI), we present teachers with approaches for helping students who need to support their learning efforts. Included are ways to use the AVSI (1) as a diagnostic tool, (2) to incorporate instruction in and modeling of volitional strategies in regular curriculum assignments, and (3) to promote student reflection and peer group interaction in facilitating self-regulatory action.
Functional traits variation explains the distribution of Aextoxicon punctatum (Aextoxicaceae) in pronounced moisture gradients within fog-dependent forest fragments

Climate change and fragmentation are major threats to world forests. Understanding how functional traits related to drought tolerance change across small-scale, pronounced moisture gradients in fragmented forests is important to predict species’ responses to these threats. In the case of Aextoxicon punctatum, a dominant canopy tree in fog-dependent rain forest patches in semiarid Chile, we explored how the magnitude, variability and correlation patterns of leaf and xylem vessel traits and hydraulic conductivity varied across soil moisture (SM) gradients established within and among forest patches of different size, which are associated with differences in tree establishment and mortality patterns. Leaf traits varied across soil-moisture gradients produced by fog interception. Trees growing at drier leeward edges showed higher leaf mass per area, trichome and stomatal density than trees from the wetter core and windward zones. In contrast, xylem vessel traits (vessels diameter and density) did not vary producing loss of hydraulic conductivity at drier leeward edges. We also detected higher levels of phenotypic integration and variability at leeward edges. The ability of A. punctatum to modify leaf traits in response to differences in SM availability established over short distances (<500 m) facilitates its persistence in contrasting microhabitats within forest patches. However, xylem anatomy showed limited plasticity, which increases cavitation risk at leeward edges. Greater patch fragmentation, together with fluctuations in irradiance and SM in small patches, could result in higher risk of drought-related tree mortality, with profound impacts on hydrological balances at the ecosystem scale.
The Language of Failure

The natural language that accompanies the accounting language in financial reports is not only a more or less accurate representation of the company but also, the authors argue, a response to explicit as well as implicit external demands, expectations, and accusations. Drawing on the notion of accounts (i.e., statements or responses that neutralize critique of not meeting expectations), the authors analyze the natural language in financial reports. In analyzing financial reports with the use of account theory, both individual actions and structurally anchored financial report discourse are approached. The theory of accounts helps the authors discern the fine-grained anatomy of financial reports by means of which impressions are managed, legitimacy is upheld, and the dialogue between companies and their public is maintained. The analysis demonstrates the presence of five types of accounts in the financial reports: excuse, justification, refocusing, concession, and mystification. Financial reporting is a legally and culturally regulated genre of business communication that partakes in the ongoing conversation between a company and its public. Understanding the role of accounts is needed to enhance the genre awareness and reader competence among the readers of financial reports.
Rosiglitazone Treatment Restores Renal Dopamine Receptor Function in Obese Zucker Rats

Abstract—Earlier we have reported a defective dopamine D1–like receptor function, which was accompanied by a decrease in D1 receptor numbers and the inability of dopamine to inhibit Na,K-ATPase and Na,H-exchanger in proximal tubules of hyperinsulinemic obese Zucker rats. The present study was designed to test the hypothesis that the defect in dopamine receptor function is a result of hyperinsulinemia in obese rats. We designed experiments to study D1 receptor function in obese Zucker rats treated with rosiglitazone, as it lowers plasma insulin by improving insulin sensitivity. A group of untreated lean and obese rats served as controls. Rosiglitazone treatment (10 mg/kg orally, 4 weeks) caused significant decreases in plasma insulin, blood glucose, and blood pressure while causing an increase in renal sodium excretion compared with untreated obese rats. In the isolated proximal tubules obtained from untreated lean rats, dopamine caused concentration-dependent inhibition of the Na,K-ATPase activity, but this inhibitory effect was absent in untreated obese rats. In rosiglitazone-treated obese rats, the inhibitory effect of dopamine on Na,K-ATPase was significantly restored. This was accompanied by a complete restoration of D1 receptor numbers in proximal tubular membranes of treated obese rats. In another set of experiments, treatment of primary proximal tubule epithelial cells in culture medium with insulin caused a significant decrease in the D1 receptor abundance, suggesting a direct role of insulin on D1 receptor regulation. We conclude that hyperinsulinemia causes downregulation of D1 receptor function and lowering of plasma insulin levels leads to restoration of renal D1 receptor function.
The end of tourism? Climate change and societal challenges

Starting with the assumption that socio-cultural aspects of tourism demand will need to change in response to global warming, this paper identifies business and consumer contradictions that highlight the complexities of dealing with climate change in an industry characterised by fragmented, global supply chains. The paper's approach is to problematise the issues into a series of research questions (related to ethical consumption, sustainability, policies, actions and communication) based on the premise that sustainable tourism is possible and desirable, but mitigation has to acknowledge the anthropogenic causes of climate change and responses should be underpinned by changing norms for any society that considers travel to be the ‘perfect freedom’.
Recovering Latent Confounders from High-dimensional Proxy Variables

Detecting latent confounders from proxy variables is an essential problem in causal effect estimation. Previous approaches are limited to low-dimensional proxies, sorted proxies, and binary treatments. We remove these assumptions and present a novel Proxy Confounder Factorization (PCF) framework for continuous treatment effect estimation when latent confounders manifest through high-dimensional, mixed proxy variables. For specific sample sizes, our two-step PCF implementation, using Independent Component Analysis (ICA-PCF), and the end-to-end implementation, using Gradient Descent (GD-PCF), achieve high correlation with the latent confounder and low absolute error in causal effect estimation with synthetic datasets in the high sample size regime. Even when faced with climate data, ICA-PCF recovers four components that explain $75.9\%$ of the variance in the North Atlantic Oscillation, a known confounder of precipitation patterns in Europe. Code for our PCF implementations and experiments can be found here: https://github.com/IPL-UV/confound_it. The proposed methodology constitutes a stepping stone towards discovering latent confounders and can be applied to many problems in disciplines dealing with high-dimensional observed proxies, e.g., spatiotemporal fields.
Acquisition of Arylsulfatase A onto the Mouse Sperm Surface During Epididymal Transit1

Abstract Arylsulfatase A (AS-A) is localized to the sperm surface and participates in sperm-zona pellucida binding. We investigated how AS-A, usually known as an acrosomal enzyme, trafficked to the sperm surface. Immunocytochemistry of the mouse testis confirmed the existence of AS-A in the acrosomal region of round and elongating spermatids. However, immunofluorescence and flow cytometry indicated the absence of AS-A on the surface of live testicular sperm. In contrast, positive AS-A staining was observed in the heads of live caudal epididymal and vas deferens sperm. The results suggested that acquisition of AS-A on the sperm surface occurred during epididymal transit. Immunocytochemistry of the epididymis revealed AS-A in narrow and apical cells in the initial segment and in clear cells in all epididymal regions. However, these epithelial cells are in the minority and are not involved in secretory activity. In the caudal epididymis and vas deferens, AS-A was also localized to principal cells, the major epithelial cells. Because principal cells have secretory activity, they may secrete AS-A into the epididymal fluid. This hypothesis was supported by our results revealing the presence of AS-A in the epididymal and vas deferens fluid (determined by immunoblotting and ELISA) and an AS-A transcript in the epididymis (by reverse transcription polymerase chain reaction). Alexa-430 AS-A bound to epididymal sperm with high affinity (Kd = 46 nM). This binding was inhibited by treatment of sperm with an antibody against sperm surface sulfogalactosylglycerolipid. This finding suggests that AS-A in the epididymal fluid may deposit onto sperm via its affinity to sulfogalactosylglycerolipid.
Integrative Nursing: Application of Principles Across Clinical Settings

While the essence of nursing has long been whole person (body, mind, and spirit) and whole system-focused, in reality the contemporary practice of nursing in many settings around the globe has become increasingly fragmented and de-stabilized. Nursing shortages in many parts of the world are significant, and hierarchies and bureaucracies often remove nurses from the point of care, be that the bedside, home, or clinic, replacing them with less skilled workers and filling their time with documentation and other administrative tasks. Integrative nursing is a framework for providing whole person/whole system care that is relationship-based and person-centered and focuses on improving the health and wellbeing of caregivers as well as those they serve. It is aligned with what is being called the “triple aim” in the United States—an effort focused on improving the patient experience (quality and satisfaction), improving the health of populations, and reducing the cost of care. The principles of integrative nursing offer clear and specific guidance that can shape and impact patient care in all clinical settings.
The Ability of the Eating Assessment Tool-10 to Detect Aspiration in Patients With Neurological Disorders

Background/Aims Dysphagia is common in patients with neurological disorders. There is a need to identify patients at risk early by a useful clinical tool to prevent its serious complications. The study aims to determine the ability of the Turkish version of Eating Assessment Tool-10 (T-EAT-10) to detect aspiration in patients with neurological disorders. Methods Two hundred fifty-nine patients with neurological disorders who had complaints about swallowing difficulty and referred for a swallowing evaluation were included. Oropharyngeal dysphagia was evaluated with the T-EAT-10 and videofluoroscopic swallowing study in the same day. The penetration-aspiration scale (PAS) was used to document the penetration and aspiration severity. Results The mean age of the patients was 59.72 ± 17.24 years (minimum [min] = 18, maximum [max] = 96), of which 57.1% were male. The mean T-EAT-10 of patients who had aspiration (PAS > 5) was 25.91 ± 10.31 (min = 1, max = 40) and the mean T-EAT-10 of patients who did not have aspiration (PAS < 6) was 15.70 ± 10.54 (min = 0, max = 40) (P < 0.001). Patients with a T-EAT-10 score higher than 15 were 2.4 times more likely to aspirate. A linear correlation was found between T-EAT-10 and PAS scores of the patients (r = 0.416, P < 0.001). The sensitivity of a T-EAT-10 higher than 15 in detecting aspiration was 81.0% and the specificity was 58.0%. A T-EAT-10 score of higher than 15 has a positive predictive value of 72.0% and a negative predictive value of 69.0%. Conclusion The T-EAT-10 can be used to detect unsafe airway protection in neurology clinics to identify and refer dysphagic patients for further evaluation.
