Heart and Brain Responses to Real Versus Simulated Chess Games in Trained Chess Players: A Quantitative EEG and HRV Study

The aim of the present study was to investigate how the heart and the brain react to playing chess with a computer versus in a real context in chess players. We also aim to investigate if familiarization with simulated practice leads to changes in heart rate variability (HRV) and the electroencephalographic (EEG) power spectrum. We designed a cross-sectional study, enrolling 27 chess players. They were randomly assigned to 3 minutes plus 2-second chess games: one with a computer (simulated scenario), and another in a real context. Additionally, participants were divided into two groups according to their level of familiarization of playing chess in a computer context. While they were playing, HRV and EEG were continuously recorded. Differences in HRV and EEG theta power spectrum between playing chess in a real or a simulated scenario were not found in chess players (p-value > 0.05). When participants were divided into groups (familiarized and unfamiliarized with simulated chess practice), significant differences were observed in HRV and EEG (p-value < 0.05). The EEG theta power spectrum was significantly lower, and HRV was higher in unfamiliarized players during the simulated scenario, which could indicate that they were less focused in a simulated environment than in a real context. Therefore, familiarization with simulated environments should be taken into account during the training process to achieve the best performance.
Clinicopathologic and molecular features of intracranial desmoplastic small round cell tumors

Desmoplastic small round cell tumors (DSRCTs) are highly aggressive sarcomas that most commonly occur intra‐abdominally, and are defined by EWSR1‐WT1 gene fusion. Intracranial DSRCTs are exceptionally rare with only seven previously reported fusion‐positive cases. Herein, we evaluate the clinical, morphologic, immunohistochemical and molecular features of five additional examples. All patients were male (age range 6–25 years; median 11 years), with four tumors located supratentorially and one within the posterior fossa. The histologic features were highly variable including small cell, embryonal, clear cell, rhabdoid, anaplastic and glioma‐like appearances. A prominent desmoplastic stroma was seen in only two cases. The mitotic index ranged from <1 to 12/10 HPF (median 5). While all tumors showed strong desmin positivity, epithelial markers such as EMA, CAM 5.2 and other keratins were strongly positive in only one, focally positive in two and negative in two cases. EWSR1‐WT1 gene fusion was present in all cases, with accompanying mutations in the TERT promoter or STAG2 gene in individual cases. Given the significant histologic diversity, in the absence of genetic evaluation these cases could easily be misinterpreted as other entities. Desmin immunostaining is a useful initial screening method for consideration of a DSRCT diagnosis, prompting confirmatory molecular testing. Demonstrating the presence of an EWSR1‐WT1 fusion provides a definitive diagnosis of DSRCT. Genome‐wide methylation profiles of intracranial DSRCTs matched those of extracranial DSRCTs. Thus, despite the occasionally unusual histologic features and immunoprofile, intracranial DSRCTs likely represent a similar, if not the same, entity as their soft tissue counterpart based on the shared fusion and methylation profiles.
Transfusing Platelets During Bypass Rewarming in Neonates Improves Postoperative Outcomes: A Randomized Controlled Trial

Background: In neonates, transfusion of platelets after hemodilution from cardiopulmonary bypass (CPB) has been standard. We hypothesize that platelet administration during the rewarming phase before termination of CPB would reduce coagulopathy, enhance hemostasis, reduce transfusion, and improve postoperative outcomes after neonatal cardiac surgery. Methods: A prospective, randomized trial was performed in 46 neonates. Controls received platelets only at the end of bypass with other blood products to assist in hemostasis. The treatment group received 10 mL/kg of platelets during the rewarming phase of bypass after cross-clamp release. After protamine, transfusion and perioperative management protocols were identical and constant among groups. Results: Two neonates in each group were excluded secondary to postoperative need for extracorporeal support. Controls (n = 21) and treatment patients (n = 21) were similar in age, weight, case complexity, associated syndromes, single ventricle status, and CPB times. Compared to controls, the treatment group required 40% less postbypass blood products (58 ± 29 vs 103 ± 80 mL/kg, P = .04), and case completion time after protamine administration was 28 minutes faster (P = .016). The treatment group required fewer postoperative mediastinal explorations for bleeding (P = .045) and had a lower fluid balance (P = .04). The treatment group had shorter mechanical ventilation (P = .016) and length of intensive care unit times (P = .033). There were no 30-day mortalities in either group. Conclusion: Platelet transfusion during the rewarming phase of neonatal cardiac surgery was associated with reduced bleeding and improved postoperative outcomes, compared to platelets given after coming off bypass. Further studies are necessary to understand mechanisms and benefits of this strategy.
Treatment of Peri-Implant Mucositis with Repeated Application of Chlorhexidine Chips or Gel during Supportive Therapy—A Randomized Clinical Trial

Running head Peri-implant maintenance with CHX Abstract Background: To assess the effect of chlorhexidine (CHX) chip application in patients with peri-implant mucositis as compared to CHX gel application. Methods: In peri-implant sites with mucositis, CHX gel was applied in the control group (GC) and CHX chips in the test group (CC) at baseline and after three months. At baseline and after six months, peri-implant pocket depths (PPD), bleeding-on-probing (BOP) and activated matrix metalloproteinase-8 (aMMP8) were assessed. Longitudinal changes were tested for inter-group differences. Results: Thirty-two patients were treated. BOP was more reduced (p = 0.006) in CC than in GC, with means and standard deviations of 46 ± 28% and 17 ± 27%, respectively. PPD was more reduced (p = 0.002) in CC than in GC with 0.65 ± 0.40 mm and 0.18 ± 0.32 mm, respectively. Regarding BOP, the percentages of improved, unchanged and worsened sites accounted for 32%, 61% and 7% in GC and 46%, 53% and 1% in CC, respectively. For probing pocket depth, the according values were 26%, 66% and 8% (GC) versus 57%, 38% and 5% (CC). Conclusions: During supportive therapy, repeated CHX chip application might resolve marginal peri-implant inflammation in terms of bleeding better than CHX gel.
Performance evaluation of three semantic expansions to query PubMed.

BACKGROUND PubMed is one of the most important basic tools to access medical literature. Semantic query expansion using synonyms can improve retrieval efficacy. OBJECTIVE The objective was to evaluate the performance of three semantic query expansion strategies. METHODS Queries were built for forty MeSH descriptors using three semantic expansion strategies (MeSH synonyms, UMLS mappings, and mappings created by the CISMeF team), then sent to PubMed. To evaluate expansion performances for each query, the first twenty citations were selected, and their relevance were judged by three independent evaluators based on the title and abstract. RESULTS Queries built with the UMLS expansion provided new citations with a slightly higher mean precision (74.19%) than with the CISMeF expansion (70.28%), although the difference was not significant. Inter-rater agreement was 0.28. Results varied greatly depending on the descriptor selected. DISCUSSION The number of citations retrieved by the three strategies and their precision varied greatly according to the descriptor. This heterogeneity could be explained by the quality of the synonyms. Optimal use of these different expansions would be through various combinations of UMLS and CISMeF intersections or unions. CONCLUSION Information retrieval tools should propose different semantic expansions depending on the descriptor and the search objectives.
Dominant ENSO frequencies during the Little Ice Age ( LIA ) in the rainshadow of the Andes-The laminated record of proglacial Lago Frías , northern Patagonia ( Argentina )

Proglacial Lago Frías in northern Patagonia is fed by the Tronador ice cap (3554 m). Previous investigations have shown that this glacier has reacted sensitively to climate change during distinct episodes such as the Late Glacial-Holocene transition (Ariztegui et al., 1997; Hajdas et al, 2003), and the Medieval Warm Epoch and the LIA, with well identified major glacial advances between A.D. 1800-1850 (Rabassa et al., 1979; Villalba et al., 1990). A meteorological record for the 1969-1985 interval at the Mascardi weather station, located at 20 km from the Frías Glacier, shows a mean annual temperature of 7.6 °C, varying from 12.9 °C in January to 2.4 °C in July. Additionally, these data indicate a strong precipitation gradient between Mascardi (1409 mm year -1) and the River Frías valley (4300 mm year -1).
Economic Growth and Complexity across Chinese Regions: the Role of Cost-saving Production Diffusion

We analyze how increases of average local wage levels contribute to economic restructuring and manufacturing industry performance across Chinese regions. In an unbalanced panel of prefectural cities and industries, spanning the years 1999-2007, we employ an instrumental variables approach to identify a causal relationship. We find that rising wages are negatively related to industry performance and show that the effect is concentrated in China’s economically most advanced regions. Industries that make intensive use of (lowskilled) labor decline, but appear to expand in locations where wages are comparatively low. We argue that this is in line with a mechanism of cost-saving industry diffusion. Comparing the economic performance of locations where such industries expand to those where they do not, we find that both economic complexity and subsequent per capita income growth increased faster in the former group. On average, the estimated relative increase amounts to 0.10-0.15 standard deviations of the local economic complexity index (ECI), which translates into 1.3-1.8 percent faster capita income growth in the years 2007-2014.
A Game Theory-based Approach for Modelling Mandatory Lane-Changing Behaviour 1 in a Connected Environment

9 The connected environment provides real-time information about surrounding traffic; such 10 information can be helpful in complex driving manoeuvres, such as lane-changing, that require 11 information about surrounding vehicles. Lane-changing modelling in the connected 12 environment has so far received little attention. This is due to the novelty of connected 13 environment, and the consequent scarcity of data. A behaviourally sound lane-changing model 14 is not even available for the traditional environment; that is, an environment without driving 15 aids. To address this need, this study develops a game theory-based mandatory lane-changing 16 model (AZHW model) for the traditional environment and extends it for the connected 17 environment. The CARRS-Q advanced driving simulator is used to collect high-quality vehicle 18 trajectory data for the connected environment. The developed models (for traditional 19 environment and connected environment) are calibrated using NGSIM and simulator data in a 20 bi-level calibration framework. The performance of the models has been rigorously evaluated 21 using various performance indicators. These include the true positive, false positive, detection 22 rate, false alarm rate, time prediction error, and location prediction error. Results consistently 23 show that the developed game theory-based models can effectively capture mandatory lane24 changing decisions with a high degree of accuracy. Furthermore, the performance of the 25 developed AZHW models is compared with representative game theory-based lane-changing 26 models in the literature. The comparative analysis reveals that the AZHW models developed 27 in this study outperform existing models. 28
Effects of Chemical Properties of Different Soils on Ganoderma Disease in Oil Palm (Elaeis guineensis)

Variations in the incidence of Ganoderma basal stem rot disease in oil palm (Elaeis guineensis) on different soils had been observed in the field. Notably, acid sulphate coastal soils were observed to have higher Ganoderma incidence compared with inland soils. Therefore, the objective of this experiment was to study the effects of four different soils belonging to five soil series, namely Parit Botak* and Jawa** series acid sulphate coastal soil, Bungor*** series inland soil, Blenheim series coastal shell deposit soil (Typic Quartzipsamments), and Kabu series limestonederived soil, coarse sandy loam (Typic Paleudults), on Ganoderma incidence and severity in oil palm seedlings in the nursery. The results show that the seedlings planted on both samples of acid sulphate coastal soils had the highest Ganoderma incidence and severity whereas those planted on coastal shell deposit soil had the lowest. Total number and weight of fruiting bodies produced at five months postinoculation were exponentially correlated to percent reduction in dry weight of Ganoderma-inoculated rubber wood blocks (RWB). Inoculated RWB from Parit Botak series were the most friable and the softest, followed by those from Jawa and Kabu series. Three sets of symptoms of Ganoderma infection were observed: a) leaf symptoms prior to initiation of Ganoderma fruiting bodies (on Bungor and Jawa series); b) leaf symptoms after initiation of Ganoderma fruiting bodies (on Blenheim and Parit Botak series); and c) a combination of the two sets (on Kabu series). Discriminant analyses elucidated that zinc, copper and calcium were associated with more than 50% disease severity index (DSI) and necrotic bole tissues. In contrast, pH, iron, manganese and nitrogen were associated with less than or 50% of DSI and necrotic bole tissues. This study illustrates the impacts of soils with different chemical compositions on the incidence and severity Ganoderma disease.

ARRANGED/LOVE MARRIAGE: INFLUENCE OF BANGLADESHI SKILLED MIGRANT PARENTS IN SYDNEY ON THEIR CHILDREN’S MARITAL PARTNER CHOICE

This paper draws upon qualitative interview data to illustrate the parents’ influence on marital partner choice of children of Bangladeshi skilled migrants in Sydney. An analysis of interview data suggests that Bangladeshi skilled migrant parents are perceived to be most influential in shaping their children’s perception of arranged or love marriage and spousal selection. The ways in which parents socialize their children around spousal selection are diverse, though, more or less, interweaved with transnational family ties as well as Bangladeshi migrant community in Sydney. However, their views on this issue change over time and context. The diversity and fluidity of parental influence challenge the dominant Western representations of migrant Muslim parents as traditionalist, collectivist and autocratic in their influence on the marital partner choices of their children.
Wage share and the current account. How income policies transmit to the rest of the world

Jorge Carrera (BCRA, UNLP) Esteban Rodríguez (BCRA) Mariano Sardi (BCRA) June 2016 Abstract This paper analyzes the relationship between inequality and the current account, addressing the role of the functional distribution of income. Using panel data for 60 countries over the period 1975–2011, our results confirm that an increase in the wage share is associated with a decrease in the current account. This result is consistent with the theories that connect higher wages with higher aggregate demand, through greater consumption and less saving. The relationship is stronger for developing economies, highlighting the structural differences between different groups of countries. Specifically, the relevance and sign of control variables like financial intermediation, fiscal balance, demographic variables, capital account openness and growth expectations varies according to the level of development. So, income policies in one country have important spillovers for partners (through the current account). These results are useful for the implementation and coordination of income policies at international level, having into account the complementary target of reducing current account imbalances.
Influence of Parapets on Wave Overtopping on Mound Breakwaters with Crown Walls

Background literature on the influence of parapets on the overtopping of mound breakwaters is limited. In this study, numerical tests were conducted using computational fluid dynamics (CFD) to analyze the influence of nine crown wall geometries (seven with parapets). The CFD model was implemented in OpenFOAM® and successfully validated with laboratory tests. A new estimator of the dimensionless mean wave-overtopping discharges (logQ) on structures with parapets is proposed. The new estimator depends on the estimation of logQ of the same structure without a parapet. The effects on wave overtopping of the parapet angle (ep), parapet width (wp), and parapet height (hp) were analyzed. Low values of ep and wp/hp ≈ 1 produced the highest parapet effectiveness to reduce the mean wave-overtopping discharges.
STRUCTURAL EVALUATION OF SEMI-RIGID STEEL PORTAL FRAMES

Over the last few years various investigations related to the development of finite element formulations for semi-rigid steel portal frame design including the geometric non-linear response have been produced. On the other hand, it is suggested that, for a more precise semirigid connection modelling, the axial and shear force effects should be incorporated to the usual bending deformations. These facts motivated the conception and development of a joint finite element that could accurately represent these effects as well as contemplated a possible interaction amongst these stiffness components. This element also enables joint elasto-plastic analysis to be performed based on their associated moment versus rotation curves. Consequently, the main aim of this paper is to describe in detail the proposed joint finite element and also its linear and non-linear formulations that incorporated the transversal deformations due to shear stresses. In order to validate and calibrate this element, and its associate formulation, a three storey semi-rigid steel portal frame proposed by Keulen et al. [4] was analysed and investigated.
Mediating role of psychological ownership on the relationship between psychological capital and burnout amongst university teachers

This research explores the mediating role of psychological ownership on the relationship between psychological capital and burnout. It also examines the differential influences of promotive and preventative psychological ownership on burnout. The purposively selected sample of 500 university teachers, from different public sector universities of Pakistan were subject to the Psychological Ownership Questionnaire, PsyCap Questionnaire and Maslach Burnout Inventory-Educator Survey. The results reveal that psychological capital fosters promotive psychological ownership that reduces the likelihood of burnout. Preventative psychological ownership, however increases the possibility of burnout.
Ontogenetic changes in the vertical distribution of giant scallop larvae, Placopecten magellanicus, in 9-m deep mesocosms as a function of light, food, and temperature stratification

To understand how thermal stratification and food abundance affects the vertical distribution of giant scallop larvae Placopecten magellanicus (Gmelin), a mesocosm study was conducted in January and February 1992. The position of larvae was followed over 55 d in replicated 9-m deep tanks in relation to a sharp thermocline and the presence or absence of phytoplankton. Growth and vertical position of larvae were monitored in separate treatments which included phytoplankton added above the thermocline, below the thermocline, throughout the mesocosm, or absent from the mesocosm. Changes in the vertical position of larvae over time were quantified with a new, profiling, video-optical instrument capable of semi-automatically identifying, counting and sizing larvae. The strong diurnal migration of scallop larvae resulted in aggregations at two interfaces: the air/water interface during the night, and at the thermocline during the day. At times, the concentration of larvae within cm of the surface was > 100 times that in the remaining water column. The formation of bioconvective cells of swimming larvae at the air/water interface allowed larval aggregations to persist throughout the period of darkness. Regardless of the distribution of food, larvae remained above the thermocline during most of the experiment. Therefore, only in those treatments where food was also present above the thermocline was larval growth relatively high. Larger larvae penetrated the thermocline only after reaching a shell length of about 200 gm; thus larval size, rather than chronological age, was more important in describing their vertical distribution. The rapid increase in kinematic viscosity with decreasing water temperature at the thermocline may retard the Communicated by J.P. Grassie, New Brunswick S.M.

The influence of larval size on their vertical distribution, and the resulting potential for horizontal transport to settlement sites, points to the importance of persistent hydrographic features as critical factors contributing to settlement variance in scallops.
Role of Training Needs Assessment in the Performance of Non-Teaching Employees at Management Level In Public Universities in Kenya

The aim of this study was to establish the role of training needs assessment in the performance of non-teaching employees in public universities in Kenya. The study was conducted in eight of the twenty-two public universities in Kenya with a sample size of 176 non-teaching employees. The study was both qualitative and quantitative. Qualitative due to descriptive statistics which were used in interpreting data and quantitative due to data obtained from questionnaires that was interpreted using statistical packages like SPSS V 20, and Stata V 12, and analysis was done by regression and correlation. The study used open and closed ended questionnaires and a Likert measurement scale of 1 to 5. The study results revealed that training need assessment (p value = 0.001) was statistically significant and therefore had a role to play in the performance of the non-academic staff at the public universities.
Does board gender diversity influence firm financial performance? Evidence from French SMEs

The issue of board gender diversity has attracted the interest of researchers as well as policymakers in recent years. Despite extensive literature examining the relationship between board gender diversity and firm financial performance, the evidence is mixed and based extensively on large firms. This study reassesses this issue by analysing a sample of French small and medium-sized enterprises (SMEs) over the period 2009-2014. We empirically controlled the direction and significance of this relationship by using panel data and the two-stage least squares (2SLS) method. In contrast to existing studies, in our work among French SMEs, we do not find a significant relationship between board gender diversity and firm financial performance. This study aims to shed light on the business case for board gender diversity.
