Detecting local diversity‐dependence in diversification

Whether there are ecological limits to species diversification is a hotly debated topic. Molecular phylogenies show slowdowns in lineage accumulation, suggesting that speciation rates decline with increasing diversity. A maximum‐likelihood (ML) method to detect diversity‐dependent (DD) diversification from phylogenetic branching times exists, but it assumes that diversity‐dependence is a global phenomenon and therefore ignores that the underlying species interactions are mostly local, and not all species in the phylogeny co‐occur locally. Here, we explore whether this ML method based on the nonspatial diversity‐dependence model can detect local diversity‐dependence, by applying it to phylogenies, simulated with a spatial stochastic model of local DD speciation, extinction, and dispersal between two local communities. We find that type I errors (falsely detecting diversity‐dependence) are low, and the power to detect diversity‐dependence is high when dispersal rates are not too low. Interestingly, when dispersal is high the power to detect diversity‐dependence is even higher than in the nonspatial model. Moreover, estimates of intrinsic speciation rate, extinction rate, and ecological limit strongly depend on dispersal rate. We conclude that the nonspatial DD approach can be used to detect diversity‐dependence in clades of species that live in not too disconnected areas, but parameter estimates must be interpreted cautiously.
esilience and recovery : The effect of triclosan exposure timing uring development , on the structure and function of river biofilm ommunities

Triclosan (TCS) is a ubiquitous antibacterial agent found in soaps, scrubs, and consumer products. There is limited information on hazardous effects of TCS in the environment. Here, rotating annular reactors were used to cultivate river biofilm communities exposed to 1.8 g l−1 TCS with the timing and duration of exposure and recovery during development varied. Two major treatment regimens were employed: (i) biofilm development for 2, 4 or 6 weeks prior to TCS exposure and (ii) exposure of biofilms to TCS for 2, 4 or 6 weeks followed by recovery. Biofilms not exposed to TCS were used as a reference condition. Communities cultivated without and then exposed to TCS all exhibited reductions in algal biomass and significant (p < 0.05) reductions in cyanobacterial biomass. No significant effects were observed on bacterial biomass. CLSM imaging of biofilms at 8 weeks revealed unique endpoints in terms of community architecture. Community composition was altered by any exposure to TCS, as indicated by significant shifts in denaturing gradient gel electrophoresis fingerprints and exopolymer composition relative to the reference. Bacterial, algal and cyanobacterial components initially exposed to TCS were significantly different from those TCS-free at time zero. Pigment analyses suggested that significant changes in composition of algal and cyanobacterial populations occurred with TCS exposure. Bacterial thymidine incorporation rates were reduced by TCS exposure and carbon utilization spectra shifted in terms substrate metabolism. Direct counts of protozoans indicated that TCS was suppressive, whereas micrometazoan populations were, in some instances, stimulated. These results indicate that even a relatively brief exposure of a river biofilm community to relatively low levels of TCS alters both the trajectory and final community structure. Although some evidence of recovery was observed, removal of TCS did not result in a return to the unexposed reference condition. Crown Copyright © 2015 Published by Elsevier B.V. All rights reserved.
Effects of the ABC Intervention on Foster Children’s Receptive Vocabulary: Follow-Up Results From a Randomized Clinical Trial

Children with histories of maltreatment and disruptions in care are at elevated risk for impairments in early language development, which contribute to difficulties in other developmental domains across childhood. Given research demonstrating associations between parent responsiveness and children’s early language development, we examined whether a parenting intervention administered in infancy improved preschool receptive language skills in children involved with the child welfare system. Attachment and Biobehavioral Catch-up (ABC) is a 10-session intervention that aims to enhance parent–child interactions. The follow-up results of this randomized clinical trial demonstrated that infants who received the ABC intervention (n = 24) scored significantly higher on a test of receptive vocabulary at age 36 months than infants who received a control intervention (n = 28). These results provide evidence of the critical role of parental responsiveness in supporting optimal language development among young children with histories of child welfare involvement.
Oral bisphosphonate use and lung cancer incidence among postmenopausal women

Abstract Background Bisphosphonates are common medications for the treatment of osteoporosis in older populations. Several studies, including the Women’s Health Initiative (WHI), have found inverse associations of bisphosphonate use with risk of breast and endometrial cancer, but little is known about its association with other common malignancies. The objective of this study was to evaluate the association of bisphosphonate use on the incidence of lung cancer in the WHI. Patients and methods The association between oral bisphosphonate use and lung cancer risk was examined in 151 432 postmenopausal women enrolled into the WHI in 1993–1998. At baseline and during follow-up, participants completed an inventory of regularly used medications including bisphosphonates. Results After a mean follow-up of 13.3 years, 2511 women were diagnosed with incident lung cancer. There was no evidence of a difference in lung cancer incidence between oral bisphosphonate users and never users (adjusted hazard ratio = 0.91; 95% confidence intervals, 0.80–1.04; P = 0.16). However, an inverse association was observed among those who were never smokers (hazard ratio = 0.57, 95% confidence interval, 0.39–0.84; P < 0.01). Conclusion In this large prospective cohort of postmenopausal women, oral bisphosphonate use was associated with significantly lower lung cancer risk among never smokers, suggesting bisphosphonates may have a protective effect against lung cancer. Additional studies are needed to confirm our findings.
3D Synergistical MXene/Reduced Graphene Oxide Aerogel for a Piezoresistive Sensor.

A piezoresistive sensor based on ultralight and superelastic aerogel is reported to fabricate MXene/reduced graphene oxide (MX/rGO) hybrid 3D structures and utilize their pressure-sensitive characteristics. The MX/rGO aerogel not only combines the rGO's large specific surface area and the MXene's (Ti3C2 T x) high conductivity but also exhibits rich porous structure, which leads to performance better than that of single-component rGO or MXene in terms of the pressure sensor. The large nanosheets of rGO can prevent the poor oxidization of MXene by wrapping MXene inside the aerogel. More importantly, the piezoresistive sensor based on the MX/rGO aerogel shows extremely high sensitivity (22.56 kPa-1), fast response time (<200 ms), and good stability over 10 000 cycles. The piezoresistive sensor based on the MX/rGO hybrid 3D aerogel can easily capture the signal below 10 Pa, thus clearly testing the pulse of an adult at random. Based on its superior performance, it also demonstrates potential applications in measuring pressure distribution, distinguishing subtle strain, and monitoring healthy activity.
Olive Tree (Olea europaea L.) Diversity in Traditional Small Farms of Ficalho, Portugal

The genetic diversity of “Gama” and “Bico de Corvo”, local cultivars of olive tree (Olea europaea) from seven traditional orchards of Ficalho (Alentejo region, Portugal), was studied to characterize the local diversity and assess the level of on farm diversity. Two different analytical systems were used: endocarp morphological characteristics and genetic analysis by microsatellite markers (Simple Sequence Repeats or SSR). The seven screened loci were polymorphic and allowed the identification of 23 distinct SSR profiles within the 27 trees analyzed. A total of 52 different alleles were scored, with an average of 7.43 alleles/SSR locus, and considerable genetic diversity was found. Neighbor-Joining algorithm cluster analysis and principal co-ordinate analysis (PCoA) allowed for the identification of the genetic relationships between several accessions. The 27 Olea accessions were clearly separated into three different groups. SSR analysis was more precise than endocarp characterization in the classification of genetic diversity among the olive tree cultivars. The study shows reasonable olive tree diversity in Ficalho, indicating that these traditional orchards are important reservoirs of old minor cultivars and incubators of new genotypes.
Partial Adjustment Toward Target R&D Intensity

Existing research assumes that once firms have determined their target R&amp;D intensity, they can adjust instantaneously and fully to their target R&amp;D intensity, regardless of their past R&amp;D intensity. In this study, we draw on the partial adjustment framework to examine the dynamics of firms' adjustment toward their target R&amp;D intensity. We find that firms usually do not adjust instantaneously or fully to their target R&amp;D intensity; they typically close half of the gap between their past and target R&amp;D intensity in a year. Furthermore, we find that the speed of adjustment varies widely across firms. Firms with more cash flows, less debt, and more new equity financing have higher speed of adjustment. We draw implications for the dynamics of R&amp;D investments and Schumpeterian competition.
Effect of Guided Imagery on Maternal Fetal Attachment in Nulliparous Women with Unplanned Pregnancy

Introduction and Objectives: Nulliparous women with unplanned pregnancy experience high levels of anxiety, which may adversely affect maternal-fetal attachment. Therefore, in this study, we aimed to determine the effect of guided imagery on maternal-fetal attachment in nulliparous women with unplanned pregnancy. Materials and Methods: In this clinical trial, 67 nulliparous women with unplanned pregnancy were randomly divided into two groups of intervention (n=35) and control (n=32) in 2015. Data collection tools included a demographic form and London, DASS 21, and Cranley's maternal-fetal attachment questionnaires. In the intervention group, one session of guided imagery on maternal role was performed in 34th week of pregnancy in groups of four to seven. Afterwards, guided imagery CDs were given to mothers to be performed at home twice a week for two weeks; the control group only received the routine care. Maternal-fetal attachment was assessed before and two weeks after the intervention. To analyze the data, independent t-test, paired t-test, Chi-squared, Fisher’s exact test, and Mann-Whitney U tests were run using SPSS version 21. Results: Maternal mean age was 24.1±4.3 years, and most mothers (49.3%) had high school education. Mean score of maternal-fetal attachment was significantly different between the intervention (94.26±6.7) and control (90.22 ± 9.5) groups after the intervention (P=0.04). Also, there was a significant difference between mean score of maternal-fetal attachment at the beginning and end of the intervention in the intervention and control groups (5.86±7.2 vs. 1.72±3.2; P=0.004). Conclusion: Guided imagery promoted maternal-fetal attachment in women with unplanned pregnancy; thus, it is recommended to use this method in prenatal care for these women.
DYNAMO ACTION AND MAGNETIC CYCLES IN F-TYPE STARS

Magnetic activity and differential rotation are commonly observed features on main-sequence F-type stars. We seek to make contact with such observations and to provide a self-consistent picture of how differential rotation and magnetic fields arise in the interiors of these stars. The three-dimensional magnetohydrodynamic anelastic spherical harmonic code is employed to simulate global-scale convection and dynamo processes in a 1.2 M☉ F-type star at two rotation rates. The simulations are carried out in spherical shells that encompass most of the convection zone and a portion of the stably stratified radiative zone below it, allowing us to explore the effects a stable zone has upon the morphology of the global-scale magnetic fields. We find that dynamo action with a high degree of time variation occurs in the star rotating more rapidly at 20 Ω☉, with the polarity of the mean field reversing on a timescale of about 1600 days. Between reversals, the magnetic energy rises and falls with a fairly regular period, with three magnetic energy cycles required to complete a reversal. The magnetic energy cycles and polarity reversals arise due to a linking of the polar-slip instability in the stable region and dynamo action present in the convection zone. For the more slowly rotating case (10 Ω☉), persistent wreaths of magnetism are established and maintained by dynamo action. Compared to their hydrodynamic progenitors, the dynamo states here involve a marked reduction in the exhibited latitudinal differential rotation, which also vary during the course of a cycle.
An Intermediation-Based Model of Exchange Rates

We develop a general equilibrium model with intermediaries at the heart of international financial markets. In our model, intermediaries bargain with their customers and extract rents for providing access to foreign claims. The behavior of intermediaries, by tilting state prices, generates an explicit, non-linear risk structure in exchange rates. We show how this endogenous risk structure helps explain a number of anomalies in foreign exchange and international capital markets, including the safe haven properties of exchange rates and the breakdown of covered interest parity.
Putting practice into words: The state of data and methods transparency in grammatical descriptions

Language documentation and description are closely related practices, often performed as part of the same fieldwork project on an un(der)-studied language. Research trends in recent decades have seen a great volume of publishing in regards to the methods of language documentation, however, it is not clear that linguists’ awareness of the importance of robust data-collection methods is translating into transparency about those methods or data citation in resultant publications. We analyze 50 dissertations and 50 grammars from a ten-year span (2003–2012) to assess the current state of the field. Publications are critiqued on the basis of transparency of data collection methods, analysis and storage, as well as citation of primary data. While we found examples of transparent reporting in these areas, much of the surveyed research does not include key information about methodology or data. We acknowledge that descriptive linguists often practice good methodology in data collection, but as a field we need to build a better culture with regard to making this clear in research writing. Thus we conclude with suggested benchmarks for the kind of information we believe is vital for creating a rich and useful research methodology in both long and short format descriptive research writing.
Unsupervised Random Forest Manifold Alignment for Lipreading

Lip reading from visual channels remains a challenging topic considering the various speaking characteristics. In this paper, we address an efficient lip reading approach by investigating the unsupervised random forest manifold alignment (RFMA). The density random forest is employed to estimate affinity of patch trajectories in speaking facial videos. We propose novel criteria for node splitting to avoid the rank-deficiency in learning density forests. By virtue of the hierarchical structure of random forests, the trajectory affinities are measured efficiently, which are used to find embeddings of the speaking video clips by a graph-based algorithm. Lip reading is formulated as matching between manifolds of query and reference video clips. We employ the manifold alignment technique for matching, where the L∞-norm-based manifold-to-manifold distance is proposed to find the matching pairs. We apply this random forest manifold alignment technique to various video data sets captured by consumer cameras. The experiments demonstrate that lip reading can be performed effectively, and outperform state-of-the-arts.
Respiratory symptoms as health status indicators in workers at ceramics manufacturing facilities.

OBJECTIVE To assess the prevalence of respiratory symptoms and their association with sociodemographic variables and with the characteristics of the work environment. METHODS A cross-sectional study comprising 464 workers employed at ceramics manufacturing facilities located in the city of Várzea Grande, Brazil. Data were collected by means of a questionnaire comprising questions regarding sociodemographic variables, work environment characteristics, and respiratory symptoms. Data were analyzed by means of prevalence ratios and their respective 95% CIs between the dependent variable (respiratory symptoms) and the other explanatory variables. In the multivariate analysis, two hierarchical models were built, the response variables being "all respiratory symptoms" and "severe respiratory symptoms". RESULTS In the sample studied, the prevalence of "all respiratory symptoms" was 78%, whereas that of "severe respiratory symptoms" was 35%. The factors associated with "all respiratory symptoms" were gender, age bracket, level of education, type of occupation, exposure to dust, and exposure to chemical products. The factors associated with "severe respiratory symptoms" were level of education, exposure to dust, and exposure to chemical products. CONCLUSIONS Our results indicate the presence of upper and lower airway disease in the population studied.
Set up for a Fall

This study considers the potentially negative consequences for corporate leaders of being subjected to high levels of ingratiation in the form of flattery and opinion conformity from other managers and board members. Chief executive officers (CEOs) who have acquired positions of relatively high social status in the corporate elite tend to be attractive targets of flattery and opinion conformity from colleagues, which can have potentially negative consequences for CEOs and their firms. Our theory suggests how high levels of flattery and opinion conformity can increase CEOs’ overconfidence in their strategic judgment and leadership capability, which results in biased strategic decision making. Specifically, we contend that heightened overconfidence from receiving high levels of such ingratiatory behavior reduces the likelihood that CEOs will initiate needed strategic change in response to poor firm performance. We tested and confirmed our hypotheses with a dataset that includes original survey data from a large sample of U.S. CEOs, other top managers, and board members in the period 2001–2007. Further analyses suggest that strategic persistence that results from high levels of flattery and opinion conformity directed at the CEO can result in the persistence of low firm performance and may ultimately increase the likelihood of the CEO’s dismissal. Implications for theory and research on social influence, sources of overconfidence in decision making, and the dynamics of executive careers are discussed.
Tissue culture of gerbera.

Gerbera (Gerbera jamesonii) somatic tissues and seeds were tried for raising tissue cultures. The explants of shoot tips, immature inflorescences, leaf sections, capitulum explants, axillary buds and receptacles explants from field grown plants had contamination problems. Another trouble was slow growth of explant cultures as they were treated with sterilizing chemicals which damage their growing regions. However, callusing was in all explants and shoot regenerations were obtained from shoot tip and axillary buds. The calluses were obtained from clean seeds which were presoaked (20mg/liter for six hours) in colchicine for induction of polyploidy. The germinating seedlings were crushed and tissue mass was put on callusing medium containing MS with BA+2,4D (each 3 mg/liter). After six weeks, the calli were transferred to MS+BA (4mg/liter) +IBA (1mg/liter). The developed plantlets were separated and cultured on MS containing BA and IBA (each @ 0.5mg/liter). The plantlets were transferred to pots under 100% humidity during initial weaning period, acclimatized and grown as normal plants.
A pain in the neck

A lateralized pain in the neck is a common symptom encountered by the otolaryngologist. This complaint, frequently caused by lateral thyrohyoid ligament syndrome, is often misdiagnosed. The pathophysiology of this syndrome may relate to overuse and inflammation. [change made here after initial online publication]. Typically, patients present with chronic unilateral neck pain often associated with odynophagia. The point of maximum tenderness localizes over the axis of the lateral thyrohyoid ligament. We present a series of 15 patients, in whom treatment with depot steroid and local anesthetic injection (n = 14) improved symptoms in 12 (86%), with complete resolution in nine (64%) patients.

Preliminary Incidence and Trends of Infections with Pathogens Transmitted Commonly Through Food — Foodborne Diseases Active Surveillance Network, 10 U.S. Sites, 2006–2017

Despite ongoing food safety measures in the United States, foodborne illness continues to be a substantial health burden. The 10 U.S. sites of the Foodborne Diseases Active Surveillance Network (FoodNet)* monitor cases of laboratory-diagnosed infections caused by nine pathogens transmitted commonly through food. This report summarizes preliminary 2017 data and describes changes in incidence since 2006. In 2017, FoodNet reported 24,484 infections, 5,677 hospitalizations, and 122 deaths. Compared with 2014-2016, the 2017 incidence of infections with Campylobacter, Listeria, non-O157 Shiga toxin-producing Escherichia coli (STEC), Yersinia, Vibrio, and Cyclospora increased. The increased incidences of pathogens for which testing was previously limited might have resulted from the increased use and sensitivity of culture-independent diagnostic tests (CIDTs), which can improve incidence estimates (1). Compared with 2006-2008, the 2017 incidence of infections with Salmonella serotypes Typhimurium and Heidelberg decreased, and the incidence of serotypes Javiana, Infantis, and Thompson increased. New regulatory requirements that include enhanced testing of poultry products for Salmonella† might have contributed to the decreases. The incidence of STEC O157 infections during 2017 also decreased compared with 2006-2008, which parallels reductions in isolations from ground beef. § The declines in two Salmonella serotypes and STEC O157 infections provide supportive evidence that targeted control measures are effective. The marked increases in infections caused by some Salmonella serotypes provide an opportunity to investigate food and nonfood sources of infection and to design specific interventions.
