The Influence of Parameter Choice on the Performance of SVM RBF Classifiers for Argumentative Zoning

Today scientists are inundated by the plethora of works that may or may not be relevant to their research interests and needs. One of the concepts proposed for overcoming this problem is Argumentative Zoning. It classifies information within scientific papers by assigning labels to sentences according to their rhetorical role. In a previous work, Support Vector Machines with RBF kernels are shown to give the best results when compared to other methods for the task of Argumentative Zoning. This paper aims to investigate the influence of further treatment on their performance, namely, using grid search for finding optimal parameter values, both under and without feature selection. Experiment results show that feature selection generally gives higher mean accuracy value when compared with when all features are used, averaging at 65.36% with a maximum value of 68.10%. However, when feature selection is not performed, using parameter values from the grid search, accuracy may reach 73.95%, although the average performance is lower. These results indicate that for the task of Argumentative Zoning with SVM RBF classifiers, good selection of parameter values is more important when compared feature set optimization.
A Medical Team’s Perspective Regarding Presence of the Family Members of Patients during Cardiopulmonary Resuscitation in the Intensive Care Unit

Introduction: The basic needs of a patient and his/her family members are to be supported during health care and especially during critical situations. One such support is required during cardiopulmonary resuscitation (CPR). Hence knowing the perspective of medical persons about “Family member’s Presence during Resuscitation” (FPDR) in the Intensive Care Unit (ICU) is important. Methods and Materials: This research was a descriptive-analytic cross-sectional study. The population consisted of 360 members of the medical team in the ICUs of educational hospitals in Rasht during 2014–2015. Data were collected by means of census sampling using a two-part questionnaire, which included demographic information and the medical team’s perspective. Fischer exact test, spearman’s coefficient, logistic regression, and the KruskalWallis test were used to analyze the results of the study. Results: The findings showed that 156 (43%) medical team members had experience of FPDR. Only 71 (19.7%) stated that they would invite family members to be present during the resuscitation process. The Fisher test showed a significant difference between the medical team’s perspective of FPDR (P=0.033), with the majority of the emergency specialists (40%) and anesthesiology (4.2%) showing the highest and lowest agreement respectively about FPDR. The logistic regression model showed that the perspective of the medical team with a Bacheler's Degree (BS). In nursing degree (OR=4.3, p<0.021), an MSC. Nursing degree (OR=6.9, P<0.018), an anesthesiologist associate degree (OR=22.5, P<0.001), a BS. anesthesiologist degree (OR=5.7, P<0.029), and an emergency specialist status (OR=19.8, P<0.032) had a more positive attitude toward FPDR compared with the general practitioners. Conclusion: Considering the medical team’s perspective of the importance of FPDR, it is necessary to formulate an instruction in ICUs to provide the grounds for it.
Instabilities in large economies: aggregate volatility without idiosyncratic shocks

We study a dynamical model of interconnected firms which allows for certain market imperfections and frictions, restricted here to be myopic price forecasts and slow adjustment of production. Whereas the standard rational equilibrium is still formally a stationary solution of the dynamics, we show that this equilibrium becomes linearly unstable in a whole region of parameter space. When agents attempt to reach the optimal production target too quickly, coordination breaks down and the dynamics becomes chaotic. In the unstable, ‘turbulent’ phase, the aggregate volatility of the total output remains substantial even when the amplitude of idiosyncratic shocks goes to zero or when the size of the economy becomes large. In other words, crises become endogenous. This suggests an interesting resolution of the ‘small shocks, large business cycles’ puzzle.
Impact of Job-Related Well-Being on the Relationship of Self-Efficacy With Burnout

The levels of job-related affective well-being and occupational self-efficacy may act as protective factors against the development of burnout. Therefore, this study investigated the role of positive and negative affect as a mediator in the relations between occupational self-efficacy and the dimensions of burnout. The research participants were 584 professionals (87% female), mean age 37.8 (SD= 10.8). The results of the structural equation modeling analysis indicated that the relations of occupational self-efficacy with emotional exhaustion and depersonalization were completely mediated by positive and negative affect. The relation between occupational self-efficacy and personal accomplishment was partially mediated by positive affect. Occupational self-efficacy was positively associated to positive affect and negatively related to negative affect. This study adds by showing the importance of developing interventions that promote the experience of positive affect and reduction of negative affect in occupational settings as a preventive strategy of burnout.
Blowing snow in coastal Adélie Land, Antarctica: three atmospheric-moisture issues

A total of 3 years of blowing-snow observations and associated meteorology along a 7 m mast at site D17 in coastal Adelie Land are presented. The observations are used to address three atmospheric-moisture issues related to the occurrence of blowing snow, a feature which largely affects many regions of Antarctica: (1) blowing-snow sublimation raises the moisture content of the surface atmosphere close to saturation, and atmospheric models and meteorological anal- yses that do not carry blowing-snow parameterizations are affected by a systematic dry bias; (2) while snowpack mod- elling with a parameterization of surface-snow erosion by wind can reproduce the variability of snow accumulation and ablation, ignoring the high levels of atmospheric-moisture content associated with blowing snow results in overestimat- ing surface sublimation, affecting the energy budget of the snowpack; (3) the well-known profile method of calculat- ing turbulent moisture fluxes is not applicable when blow- ing snow occurs, because moisture gradients are weak due to blowing-snow sublimation, and the impact of measure- ment uncertainties are strongly amplified in the case of strong winds.
The Dark Side of Retailing: Towards a Scale of Corporate Social Irresponsibility

Purpose – Corporate social responsibility is becoming increasingly important in the retailing industry, whereby retailers are frequently criticized for socially irresponsible business practices by mass media and consumer advocacy groups. The purpose of this research is to find out which retail business practices lead to perceptions of corporate social irresponsibility (CSIR) from the customers' perspective and to develop a measurement scale for this construct. Design/methodology/approach – Using quantitative data from a paper-based and an online survey, a higher-order, multi-group confirmatory factor analysis was conducted. Findings – The research identifies 14 factors which represent perceptions of CSIR in retailing. A measurement scale of this construct is proposed and empirically validated. Demographic differences among consumers' CSIR perceptions are revealed. Research limitations/implications – The scale remains to be validated in varying cultural settings other than the USA. Practical implications – The findings provide retailers with a detailed account of business practices that consumers regard as socially irresponsible. The scale can be adopted by retailers in surveys to measure consumers' perceptions. Originality/value – The paper is first in providing a conceptualization and measurement scale for CSIR which is of increasing importance for both retailing theory and practice.
The Solomon Sea: its circulation, chemistry, geochemistry and biology explored during two oceanographic cruises

The semi-enclosed Solomon Sea in the southwestern tropical Pacific is on the pathway of a major oceanic circuit connecting the subtropics to the equator via energetic western boundary currents. Waters transiting through this area replenish the Pacific Warm Pool and ultimately feed the equatorial current system, in particular the equatorial undercurrent. In addition to dynamical transformations, water masses undergo nutrient and micronutrient enrichment when coming in contact with the coasts, impacting the productivity of the downstream equatorial region. Broadscale observing systems are not well suited for describing the fine-scale currents and water masses properties in the Solomon Sea, leaving it relatively unexplored. Two multidisciplinary oceanographic cruises were conducted in the Solomon Sea region, the first in July – August 2012 and the second in March 2014, by investigators from France and the United States. The experimental approach combined physical, chemical, geochemical and biogeochemical analyses, providing access to a wide range of space and time scales of the circulation. This collection of data allows describing the fine-scale structure of the currents and the water properties, transformations and mixing from the surface to the sill depth in the Solomon Sea and in the straits connecting it to the equator. Ocean-margin exchanges were documented through a comprehensive sampling of trace elements and isotopes as efficient tracers of natural fertilization processes. As air chemistry is largely impacted by the regional volcanic plumes, rainwater pH was also sampled. Dinitrogen fixation rates were measured and found to be among the highest in the global ocean, highlighting this region as a hot spot of nitrogen fixation. This study provides an overview of the climatic context during both cruises and the physical circulation and water masses properties. It provides a comprehensive description of all measurements made onboard, and presents preliminary results, aiming to serve as a reference for further physical, geochemical and biogeochemical studies.
Osmotic traps for colloids and macromolecules based on logarithmic sensing in salt taxis

Diffusiophoretic motion of colloids and macromolecules under salt gradients exhibits a logarithmic-sensing, i.e. the particle velocity is proportional to the spatial gradient of the logarithm of the salt concentration, as VDP = DDP∇logc. Here we explore experimentally the implications of this log-sensing behavior, on the basis of a hydrogel microfluidic device allowing to build spatially and temporally controlled gradients. We first demonstrate that the non-linearity of the salt-taxis leads to a trapping of particles under concentration gradient oscillations via a rectification of the motion. As an alternative, we make use of the high sensitivity of diffusiophoretic migration to vanishing salt concentration due to the log-sensing: in a counter-intuitive way, a vanishing gradient can lead to measurable velocity provided that the solute concentration is low enough, thus keeping ∇c/c finite. We show that this leads to a strong segregation of particles in osmotic shock configuration, resulting from a step change of the salt concentration at the boundaries. These various phenomena are rationalized on the basis of a theoretical description for the time-dependent Smoluchowski equation for the colloidal density.
THE PROPENSITY FOR DEPENDENCE IN SMALL CARIBBEAN AND PACIFIC ISLANDS

Why has the postwar march to independence stalled among small tropical islands? Why do dependent islands continue to vote for the status quo? The primary explanation in the literature is the substantial economic benefits conferred by politi- cal affiliation: preferential metropolitan trade, investment and migration opportunities and subsidized infrastructure funding. This study compares 16 dependent with 19 independent islands in the Caribbean and Pacific across 25 socio-economic and demo- graphic indicators. The former significantly out-perform their larger sovereign rivals across most indices. Results suggest the dependencies have more successfully restructured their colonial economies, have progressed further along the demographic transi- tion, and constitute a new insular development case: the small service-driven dependent island economy.

Accounting standards, law original, tax rates and the development of corporate debt security markets

In this study, the factors affecting the development of the domestic corporate debt market are investigated and linear models modeling the development are built. It is found that the accounting standards, corporate tax rates and effective legal systems have positive effects on the development of the domestic corporate debt market. The estimated results show that the development of the domestic government debt securities as well as the development of the domestic equity market influence the development of the domestic corporate debt market positively. The regional analysis not shows that claim that Asia Crisis in 1997 resulted from the weak financial systems and the underdeveloped debt markets in Asian countries may not be correct.
THE EFFECT OF TOOL PRESS FORCE TO WELDABILITY OF AA5754 AND AA6061 ALLOYS WITH FRICTION STIR WELDING METHOD

In this study AA5754 and A6061 alloys have been butt welded to each other by using friction stir welding (FSW). At constant tool geometry and tool angle experiments were carried out, joints were performed using different welding speed, rotation speed and especially tool press force. The mechanical properties of the welded samples were determined by using tensile test, bending test and micro hardness. Generated microstructure and hardness profile was obtained in the welding zone. In this friction stir welding study the parameters which affect the joint structure are the tool press force, welding speed and tool rotation speed which were determined. At the end of study it is determined that AA5754 and AA6061 alloys can be successfully welded by using Friction Stir Welding method under different tool press forces at least 6kN.
Effect of Increasing External Loads on Countermovement Jump Landing Kinetics between NCAA DI Women's Soccer and Gymnastics on Land vs in Water

The purpose of this study was to compare the effect of differing loads on landing kinetics on land, and in aquatic conditions. Twenty four NCAA DI athletes volunteered for this study twelve female soccer players and twelve female gymnasts. Participants performed three jumps with four differing external loads in both land and aquatic environments. External loads were body weight (BW), BW*1.1, BW*1.2, BW*1.3 and applied via a weighted vest. All external loads for both conditions were added based upon participants BW on land. Kinetic measures were peak force, rate of force development, and impulse of the landing phase of the plyometric countermovement jump. Data was collected via waterproof force-plate. Results were analyzed using a three-way repeated measures 2x2x4 ANOVA. There was no significant difference in any result based on sport. Aquatic environments reduced peak impact by 50.7%, rate of force development by 53.5%, and impulse by 38.6%. Increasing external load did not produce significant differences for impact peak force or rate of force development, but did produce significantly higher impact impulse for land based jumps (p=0.000). In an aquatic environment increasing load produced significant differences in all three kinetic values. The results for environment agree with previous studies. The results for loaded aquatic countermovement jumps in this study show increased landing kinetics over unloaded aquatic jumps, and decreased landing kinetics over unloaded land jumps. Adding external load in aquatic environments may utilized to increase landing kinetics, while remaining under kinetic values of land based plyometrics. EFFECT OF INCREASING EXTERNAL LOADS 3

Some New Existence Results of Positive Solutions to an Even-Order Boundary Value Problem on Time Scales

We consider a high-order three-point boundary value problem. Firstly, some new existence results of at least one positive solution for a noneigenvalue problem and an eigenvalue problem are established. Our approach is based on the application of three different fixed point theorems, which have extended and improved the famous Guo-Krasnosel’skii fixed point theorem at different aspects. Secondly, some examples are included to illustrate our results.
An overview of constitutive models for shape memory alloys

The remarkable properties of shape memory alloys have facilitated their applications in many areas of technology. The purpose of this paper is to present an overview of thermomechanical behavior of these alloys, discussing the main constitutive models for their mathematical description. Metallurgical features and engineering applications are addressed as an introduction. Afterwards, five phenomenological theories are presented. In general, these models capture the general thermomechanical behavior of shape memory alloys, characterized by pseudoelasticity, shape memory effect, phase transformation phenomenon due to temperature variation, and internal subloops due to incomplete phase transformations.
Arbuscular mycorrhizal fungal communities in an iron mining area and its surroundings: Inoculum potential, density, and diversity of spores related to soil properties

Fungos micorrizicos arbusculares (AMF) interagem simbioticamente com a maioria das especies de plantas, facilitando a revegetacao de areas sob reabilitacao. O objetivo deste trabalho foi de avaliar o potencial de inoculo, densidade e diversidade de esporos de AMF em cinco ambientes, e a relacao das especies com atributos do solo. Amostras de solo foram coletadas em cinco ambientes em area de mineracao e seu entorno no Quadrilatero Ferrifero, Minas Gerais (Brasil): pilha de rejeitos em reabilitacao com capim, canga, Cerrado, mata nativa e plantacao de eucalipto, e submetidas a analises quimica e fisica. A extracao de esporos direto de amostras de campo e de culturas armadilha (TCs), estabelecidas em dois locais nas regioes Sul e Sudeste do Brasil, foi feita para identificacao taxonomica das especies. Foram determinados riqueza de especies, indice de diversidade de Shannon (H’) e equitabilidade. Analise de componentes principais (PCA) foi utilizada para identificar atributos do solo que mais influenciaram a ocorrencia de AMF. A densidade de esporos nao diferiu significativamente entre os ambientes. Um total de 59 especies de AMF foram encontradas, destacando-se o primeiro relato de ocorrencia de Acaulospora nivalis e Acaulospora alpina no Brasil. Maiores H’ e riqueza de especies no campo foram encontradas em pilhas de rejeitos e menores em canga, embora canga tenha apresentado maior potencial de inoculo. A conducao de TCs em dois locais proporcionou captura de maior diversidade de especies de AMF. Ambientes do Quadrilatero Ferrifero sao hotspots de diversidade de AMF e o pH do solo e teores trocaveis ​​de S e P sao os atributos que melhor explicam a distribuicao das especies de AMF.
Socio-economic effects of an earthquake:does sub-regional counterfactual sampling matter in estimates? An empirical test on the 2012 Emilia-Romagna earthquake

Estimates of macroeconomic effects of natural disaster have a long tradition in economic literature (Albala-Bertrand, 1993a; 1993b; Tol and Leek, 1999; Chang and Okuyama, 2004; Benson and Clay, 2004; Stromberg, 2007; UNISDR, 2009; Cuaresma, 2009; Cavallo and Noy, 2009; Cavallo et al., 2010; The United Nations and The World Bank, 2010). After the seminal contribution of Abadie et al. (2010) in identifying synthetic control groups, with DuPont and Noy (2015) a new strand has been opened in estimating long term effects of natural disaster at a sub-regional scale, at which the Japan case provides plenty of significant economic variables. Although the same methodology has been applied in estimating the impact of earthquakes in Italy (Barone et al. 2013; Barone and Mocetti, 2014), the analysis has been limited to the regional scale. In our paper, due to a lack in long-term time series data at municipality level, this paper cannot adopt the methodology suggested by Abadie et al. (2010). Nevertheless, it provides a test bed for assessing the relevance of a sub-regional counterfactual evaluation of a natural disaster's impact. By taking the 2012 Emilia-Romagna earthquake as a case study, we propose a comprehensive framework to answer some critical questions arising in such analysis. Firstly, we address the problem of identifying the proper boundaries of the area affected by an earthquake. Secondly, through a cluster analysis we show the importance of intra area differences in terms of their socio-economic features. Thirdly, counterfactual analysis is assessed by adopting a pre- and post-earthquake difference-in-difference comparison of average data in clusters within and outside the affected area. Moreover, three frames to apply propensity score matching at municipality level are also adopted, by taking the control group of municipalities (outside the affected area): (a) within the same cluster, (b) within the same region, (c) in the whole country. The four variables considered in the counterfactual analysis are: total population; foreigner population; total employment in manufacturing local units; employment in small and medium-sized manufacturing local units (0 to 49 employees). All the counterfactual tests largely show a similar result: socio-economic effects are heterogeneous across the affected area, where some clusters of municipalities perform better, in terms of increase of population and employment after the earthquake, against some others. This result sharply contrasts with the average results we observe by comparing the whole affected area with the non-affected one or with the entire region.
