A geographic approach for combining social media and authoritative data towards identifying useful information for disaster management

In recent years, social media emerged as a potential resource to improve the management of crisis situations such as disasters triggered by natural hazards. Although there is a growing research body concerned with the analysis of the usage of social media during disasters, most previous work has concentrated on using social media as a stand-alone information source, whereas its combination with other information sources holds a still underexplored potential. This article presents an approach to enhance the identification of relevant messages from social media that relies upon the relations between georeferenced social media messages as Volunteered Geographic Information and geographic features of flood phenomena as derived from authoritative data (sensor data, hydrological data and digital elevation models). We apply this approach to examine the micro-blogging text messages of the Twitter platform (tweets) produced during the River Elbe Flood of June 2013 in Germany. This is performed by means of a statistical analysis aimed at identifying general spatial patterns in the occurrence of flood-related tweets that may be associated with proximity to and severity of flood events. The results show that messages near (up to 10 km) to severely flooded areas have a much higher probability of being related to floods. In this manner, we conclude that the geographic approach proposed here provides a reliable quantitative indicator of the usefulness of messages from social media by leveraging the existing knowledge about natural hazards such as floods, thus being valuable for disaster management in both crisis response and preventive monitoring.
Sucking while swimming: evaluating the effects of ram speed on suction generation in bluegill sunfish Lepomis macrochirus using digital particle image velocimetry

SUMMARY It is well established that suction feeding fish use a variable amount of swimming (ram) during prey capture. However, the fluid mechanical effects of ram on suction feeding are not well established. In this study we quantified the effects of ram on the maximum fluid speed of the water entering the mouth during feeding as well as the spatial patterns of flow entering the mouth of suction-feeding bluegill sunfish Lepomis macrochirus. Using Digital Particle Image Velocimetry (DPIV) and high-speed video, we observed the flow in front of the mouth of three fish using a vertical laser sheet positioned on the mid-sagittal plane of the fish. From this we quantified the maximum fluid speed (measured at a distance in front of the mouth equal to one half of the maximum mouth diameter), the degree of focusing of water flow entering the mouth, and the shape of the ingested volume of water. Ram speed in 41 feeding sequences, measured at the time of maximum gape, ranged between 0 and 25 cm s–1, and the ratio of ram speed to fluid speed ranged from 0.1% to 19.1%. In a regression ram speed did not significantly affect peak fluid speed, but with an increase in ram speed the degree of focusing of water entering the mouth increased significantly, and the shape of the ingested volume of water became more elongate and narrow. The implications of these findings are that (1) suction feeders that employ ram of between 0% and 20% of fluid speed sacrifice little in terms of the fluid speeds they generate and (2) ram speed enhances the total body closing speed of the predator.
Effect of nitrogen on the seasonal course of growth and maintenance respiration in stems of Norway spruce trees.

To determine effects of stem nitrogen concentration ([N]) on the seasonal course of respiration, rates of stem respiration of ten control and ten irrigated-fertilized (IL), 30-year-old Norway spruce trees (Picea abies (L.) Karst. ), growing in northern Sweden, were measured on seven occasions from June 1993 to April 1994. To explore sources of seasonal variation and mechanisms of fertilization effects on respiration, we separated total respiration into growth and maintenance respiration for both xylem and phloem bark. Stem respiration increased in response to the IL treatment and was positively correlated with growth rate, volume of living cells and stem nitrogen content. However, no significant effect of IL treatment or [N] in the living cells was found for respiration per unit volume of live cells. Total stem respiration during the growing season (June to September) was estimated to be 16.7 and 29.7 mol CO(2) m(-2) for control and IL-treated trees, respectively. Respiration during the growing season accounted for approximately 64% of total annual respiration. Depending on the method, estimated growth respiration varied between 40 and 60% of total respiration during the growing season. Between 75 and 80% of the live cell volume in the stems was in the phloem, and phloem maintenance accounted for about 70% of maintenance respiration. Because most of the living cells were found in the phloem, and the living xylem cells were concentrated in the outer growth rings, we concluded that the best base for expressing rates of stem growth and maintenance respiration in young Norway spruce trees is stem surface area.
Effects of monensin and dietary soybean oil on milk fat percentage and milk fatty acid profile in lactating dairy cows.

The objective of this study was to investigate the effect of monensin (MN) and dietary soybean oil (SBO) on milk fat percentage and milk fatty acid (FA) profile. The study was conducted as a randomized complete block design with a 2 x 3 factorial treatment arrangement using 72 lactating multiparous Holstein dairy cows (138 +/- 24 d in milk). Treatments were [dry matter (DM) basis] as follows: 1) control total mixed ration (TMR, no MN) with no supplemental SBO; 2) MN-treated TMR (22 g of MN/kg of DM) with no supplemental SBO; 3) control TMR including 1.7% SBO; 4) MN-treated TMR including 1.7% SBO; 5) control TMR including 3.4% SBO; and 6) MN-treated TMR including 3.4% SBO. The TMR (% of DM; corn silage, 31.6%; haylage, 21.2%; hay, 4.2%; high-moisture corn, 18.8%; soy hulls, 3.3%; and protein supplement, 20.9%) was offered ad libitum. The experiment consisted of a 2-wk baseline, a 3-wk adaptation, and a 2-wk collection period. Monensin, SBO, and their interaction linearly reduced milk fat percentage. Cows receiving SBO with no added MN (treatments 3 and 5) had 4.5 and 14.2% decreases in milk fat percentage, respectively. Cows receiving SBO with added MN (treatments 4 and 6) had 16.5 and 35.1% decreases in milk fat percentage, respectively. However, the interaction effect of MN and SBO on fat yield was not significant. Monensin reduced milk fat yield by 6.6%. Soybean oil linearly reduced milk fat yield and protein percentage and linearly increased milk yield and milk protein yield. Monensin and SBO reduced 4% fat-corrected milk and had no effect on DM intake. Monensin interacted with SBO to linearly increase milk fat concentration (g/100 g of FA) of total trans-18:1 in milk fat including trans-6 to 8, trans-9, trans-10, trans-11, trans-12 18:1 and the concentration of total conjugated linoleic acid isomers including cis-9, trans-11 18:2; trans-9, cis-11 18:2; and trans-10, cis-12 18:2. Also, the interaction increased milk concentration of polyunsaturated fatty acids. Monensin and SBO linearly reduced, with no significant interaction, milk concentration (g/100 g of FA) of short- and medium-chain fatty acids (
Positive intelligence illusions: on the relation between intellectual self-enhancement and psychological adjustment.

The relation between self-enhancement and psychological adjustment has been debated for over 2 decades. This controversy is partly due to the variety of approaches implicated in the assessment of mainly self-enhancement but also psychological adjustment. We adopted a face-valid approach by statistically removing actual intellectual ability variance from self-rated intellectual ability variance. Study 1 (N = 2,048), a concurrent Internet investigation, provided initial insight into the relation between intellectual self-enhancement and psychological adjustment. Study 2 (N = 238), a longitudinal round-robin investigation, allowed a closer examination of the dynamic processes underlying this relation. Self-enhancement was positively linked to multiple indicators of intrapersonal and interpersonal adjustment, and predicted rank-order increases in adjustment over time. The links between intellectual self-enhancement and intrapersonal adjustment were mediated by self-esteem. Finally, the interpersonal costs and benefits of self-enhancement systematically varied depending on methodology.
Popular Ensemble Methods: An Empirical Study

An ensemble consists of a set of individually trained classifiers (such as neural networks or decision trees) whose predictions are combined when classifying novel instances. Previous research has shown that an ensemble is often more accurate than any of the single classifiers in the ensemble. Bagging (Breiman, 1996c) and Boosting (Freund & Schapire, 1996; Schapire, 1990) are two relatively new but popular methods for producing ensembles. In this paper we evaluate these methods on 23 data sets using both neural networks and decision trees as our classification algorithm. Our results clearly indicate a number of conclusions. First, while Bagging is almost always more accurate than a single classifier, it is sometimes much less accurate than Boosting. On the other hand, Boosting can create ensembles that are less accurate than a single classifier - especially when using neural networks. Analysis indicates that the performance of the Boosting methods is dependent on the characteristics of the data set being examined. In fact, further results show that Boosting ensembles may overfit noisy data sets, thus decreasing its performance. Finally, consistent with previous studies, our work suggests that most of the gain in an ensemble's performance comes in the first few classifiers combined; however, relatively large gains can be seen up to 25 classifiers when Boosting decision trees.

Leaders influence followers in many ways; one way is by eliciting positive emotions. In three studies we demonstrate that the nearly unstudied moral emotion of 'elevation' (a reaction to moral excellence) mediates the relations between leaders' and their followers' ethical behavior. Study 1 used scenarios manipulated experimentally; study 2 examined employees' emotional responses to their leaders in a natural work setting; study 3 compared the effects of elevation to those of happiness, serenity, and positive affect. We found that leaders' interpersonal fairness and self-sacrifice are powerful elicitors of elevation, and that this emotion fully mediates leaders' influence on followers' organizational citizenship behavior and affective organizational commitment. In the first study, we also observed a moderation effect of interpersonal fairness on self-sacrifice. Results underline the importance of positive moral emotions in organizations and shed light on the emotional process by which ethical leaders can foster positive organizational outcomes. Introduction Ethical issues are perennially important in leadership studies. Several high-profile ethical scandals (such as Enron), as well as the role of ethically suspect practices in bringing about the worldwide collapse of financial institutions in 2008, have made the relationship between ethics and leadership an even more pressing area for research. Many hypotheses have been brought forward in order to understand how leaders can foster moral behaviors among employees and organizations. When he originally introduced transformational leadership, Burns (1978) explicitly relied on Kohlberg's (1969) theory of cognitive moral development, arguing that transformational leaders move followers to higher stages of moral reasoning. Later on, the morality of transformational leadership was seriously questioned. Each of the four components of the construct of transformational leadership – idealized influence, inspirational motivation, intellectual stimulation, and – has an ethical dimension but, as Bass …
Clinical Genetic Evaluation of the Child With Mental Retardation or Developmental Delays

This clinical report describes the clinical genetic evaluation of the child with developmental delays or mental retardation. The purpose of this report is to describe the optimal clinical genetics diagnostic evaluation to assist pediatricians in providing a medical home for children with developmental delays or mental retardation and their families. The literature supports the benefit of expert clinical judgment by a consulting clinical geneticist in the diagnostic evaluation. However, it is recognized that local factors may preclude this particular option. No single approach to the diagnostic process is supported by the literature. This report addresses the diagnostic importance of clinical history, 3-generation family history, dysmorphologic examination, neurologic examination, chromosome analysis (≥650 bands), fragile X molecular genetic testing, fluorescence in situ hybridization studies for subtelomere chromosome rearrangements, molecular genetic testing for typical and atypical presentations of known syndromes, computed tomography and/or magnetic resonance brain imaging, and targeted studies for metabolic disorders.
Identification of Hepatoprotective Constituents in Limonium tetragonum and Development of Simultaneous Analysis Method using High-performance Liquid Chromatography

Background: Limonium tetragonum, a naturally salt-tolerant halophyte, has been studied recently and is of much interest to researchers due to its potent antioxidant and hepatoprotective activities. Objective: In the present study, we attempted to elucidate bioactive compounds from ethyl acetate (EtOAc) soluble fraction of L. tetragonum extract. Furthermore, the simultaneous analysis method of bioactive EtOAc fraction of L. tetragonum has been developed using high-performance liquid chromatography (HPLC). Materials and Methods: Thirteen compounds have been successfully isolated from EtOAc fraction of L. tetragonum, and the structures of 1–13 were elucidated by extensive one-dimensional and two-dimensional spectroscopic methods including 1H-NMR, 13C-NMR, 1H-1H COSY, heteronuclear single quantum coherence, heteronuclear multiple bond correlation, and nuclear Overhauser effect spectroscopy. Hepatoprotection of the isolated compounds against liver fibrosis was evaluated by measuring inhibition on hepatic stellate cells (HSCs) undergoing proliferation. Results: Compounds 1–13 were identified as gallincin (1), apigenin-3-O-β-D-galactopyranoside (2), quercetin (3), quercetin-3-O-β-D-galactopyranoside (4), (−)-epigallocatechin (5), (−)-epigallocatechin-3-gallate (6), (−)-epigallocatechin-3-(3″-O-methyl) gallate (7), myricetin-3-O-β-D-galactopyranoside (8), myricetin-3-O-(6″-O-galloyl)-β-D-galactopyranoside (9), myricetin-3-O-α-L-rhamnopyranoside (10), myricetin-3-O-(2″-O-galloyl)-α-L-rhamnopyranoside (11), myricetin-3-O-(3″-O-galloyl)-α-L-rhamnopyranoside (12), and myricetin-3-O-α-L-arabinopyranoside (13), respectively. All compounds except for 4, 8, and 10 are reported for the first time from this plant. Conclusion: Myricetin glycosides which possess galloyl substituent (9, 11, and 12) showed most potent inhibitory effects on the proliferation of HSCs.

“Beware the Jabberwock, dear reader!” Testing the distributional reality of construction semantics

Notwithstanding the success of the notion of construction, the computational tradition still lacks a way to represent the semantic content of these linguistic entities. Here we present a simple corpus-based model implementing the idea that the meaning of a syntactic construction is intimately related to the semantics of its typical verbs. It is a two-step process, that starts by identifying the typical verbs occurring with a given syntactic construction and building their distributional vectors. We then calculated the weighted centroid of these vectors in order to derive the distributional signature of a construction. In order to assess the goodness of our approach, we replicated the priming effect described by Johnson and Golberg (2013) as a function of the semantic distance between a construction and its prototypical verbs. Additional support for our view comes from a regression analysis showing that our distributional information can be used to model behavioral data collected with a crowdsourced elicitation experiment.
Effect of moderate alcohol consumption on plasma dehydroepiandrosterone sulfate, testosterone, and estradiol levels in middle-aged men and postmenopausal women: a diet-controlled intervention study.

BACKGROUND Moderate alcohol consumption is inversely associated with cardiovascular diseases. Changes in hormone levels might in part help explain the positive health effect. This study was performed to examine the effect of moderate alcohol consumption on plasma dehydroepiandrosterone sulfate (DHEAS), testosterone, and estradiol levels. METHODS In a randomized, diet-controlled, crossover study, 10 middle-aged men and 9 postmenopausal women, all apparently healthy, nonsmoking, and moderate alcohol drinkers, consumed beer or no-alcohol beer with dinner during two successive periods of 3 weeks. During the beer period, alcohol intake equaled 40 and 30 g per day for men and women, respectively. The total diet was supplied and had essentially the same composition during these 6 weeks. Before each treatment there was a 1 week washout period, in which the subjects were not allowed to drink alcoholic beverages. At the end of each of the two experimental periods, fasting blood samples were collected in the morning. RESULTS Moderate alcohol consumption increased plasma DHEAS level by 16.5% (95% confidence interval, 8.0-24.9), with similar changes for men and women. Plasma testosterone level decreased in men by 6.8% (95% confidence interval, -1.0- -12.5), but no effect was found in women. Plasma estradiol level was not affected. Serum high-density lipoprotein cholesterol level increased by 11.7% (95% confidence interval, 7.3-16.0), with similar changes for men and women. The overall alcohol-induced relative changes in DHEAS, testosterone, and estradiol correlated positively with the relative increase in high-density lipoprotein cholesterol (adjusted for the relative change in body weight); however, findings were only borderline significant for DHEAS and estradiol (r = 0.44, p = 0.08; r = 0.32, p = 0.21; and r = 0.46, p = 0.06, respectively). CONCLUSIONS A protective effect of moderate alcohol consumption for cardiovascular disease risk may in part be explained by increased plasma DHEAS level.
Progressive left ventricular dysfunction and remodeling after myocardial infarction.

ventricular volume. Therefore, a cutpoint of 8% for an increase in EDVI was chosen. We agree with Dr Armstrong that the results of discriminant analysis should be applied with caution, as outlined in the discussion on page 762. Of particular importance are the baseline characteristics of the study population, which include age as well as other variables (Table 1). ' Multivariate discriminant analysis in the present study was used to derive variables that allow to predict the development of left ventricular dilatation and dysfunction, which belong to the most powerful determinants of mortality after infarction. The finding of Pfeffer et al5 to which Dr Armstrong's last comment might refer to-that captopril significantly reduced the risk for reinfarction-is an important and extremely exciting finding. However, the respective mechanisms and the characteristics of the patients at risk should be known before angiotensin convering enzyme inhibitors may be recommended in general for the prevention of reinfarction. Nevertheless, the variables identified by multivariate analysis in our study (Table 4)1 allow identification of patients at high risk for progressive left ventricular dilatation and late deterioration of ventricular performance within 4 weeks after infarction who, at current understanding, may have the greatest benefit from therapy with angiotensin converting enzyme inhibitors.

Cloacibacillus porcorum sp. nov., a mucin-degrading bacterium from the swine intestinal tract and emended description of the genus Cloacibacillus

A novel anaerobic, mesophilic, amino-acid-fermenting bacterium, designated strain CL-84T, was isolated from the swine intestinal tract on mucin-based media. Cells were curved rods (0.8–1.2×3.5–5.0 µm), stained Gram-negative and were non-motile with no evidence of spores. Strain CL-84T produced acetate, propionate, formate and butyrate as the end products of metabolism when grown on serine. Optimum growth occurred at 39 °C and pH 6.5. The major cellular fatty acids were iso-C15 : 0, iso-C15 : 0 3-OH, iso-C17 : 0 and C16 : 0, distinguishing strain CL-84T from closely related species. The DNA G+C content of strain CL-84T was 55.1 mol%. 16S rRNA gene sequence analysis showed that strain CL-84T shared 90–95 % similarity with characterized genera within the phylum Synergistetes, family Synergistaceae. Phylogenetic analysis showed that strain CL-84T was related to, but distinct from, Cloacibacillus evryensis. Based on these findings, we propose that strain CL-84T represents a novel species of the genus Cloacibacillus. We further propose the name Cloacibacillus porcorum sp. nov. be designated for this species. The type strain is CL-84T ( = DSM 25858T = CCUG 62631T). An emended description of the genus Cloacibacillus is provided.
The chemokine receptor CXCR7 functions to regulate cardiac valve remodeling

CXCR7 (RDC1), a G‐protein‐coupled receptor with conserved motifs characteristic of chemokine receptors, is enriched in endocardial and cushion mesenchymal cells in developing hearts, but its function is unclear. Cxcr7 germline deletion resulted in perinatal lethality with complete penetrance. Mutant embryos exhibited aortic and pulmonary valve stenosis due to semilunar valve thickening, with occasional ventricular septal defects. Semilunar valve mesenchymal cell proliferation increased in mutants from embryonic day 14 onward, but the cell death rate remained unchanged. Cxcr7 mutant valves had increased levels of phosphorylated Smad1/5/8, indicating increased BMP signaling, which may partly explain the thickened valve leaflets. The hyperproliferative phenotype appeared to involve Cxcr7 function in endocardial cells and their mesenchymal derivatives, as Tie2‐Cre Cxcr7flox/− mice had semilunar valve stenosis. Thus, CXCR7 is involved in semilunar valve development, possibly by regulating BMP signaling, and may contribute to aortic and pulmonary valve stenosis.
