Abstract Objectives: The aim of this study is to evaluate the effect of weather conditions on post-tonsillectomy haemorrhage. Methods: One-year period retrospective chart review. The charts of all patients who underwent bilateral tonsillectomy or adenotonsillectomy were reviewed. All patients with second- ary post-tonsillectomy haemorrhage were included. The local meteorological data for the duration of the study including monthly minimum, maximum temperatures and relative humidity were obtained from the meteorological watch office in Diyarbak›r. The relationship between secondary post-tonsil- lectomy haemorrhage and weather variables was studied. Statistical analysis was performed using SPSS for Windows ver- sion 13 (Chicago, IL, USA). One sample t-test and linear regression analysis were performed. Results: 1210 consecutive patients' charts were reviewed. Overall haemorrhage rate was 5.52%. There was no statistical significance in secondary haemorrhage rates between different months of the year (p=0.99). Linear regression test revealed no statistical association between mean maximum temperature, mean minimum temperature, mean relative humidity and sec- ondary haemorrhage rates (p=0.47, p=0.06, p=0.71, respec- tively). Conclusion: Literary data regarding the effect of weather on post-tonsillectomy haemorrhage is limited and shows incon- sistency. This study shows that there is no correlation between post-tonsillectomy haemorrhage and weather variables, even with a fluctuating range of -3.3 to 40.9 °C in temperature.
A MULTI CONSTRAINED QOS ROUTING ALGORITHM FOR VEHICULAR ADHOC NETWORKS

Secure Quality of Service (QoS) directing calculations are a crucial piece of remote systems that plan to give administrations QoS and security ensures. In vehicular specially appointed systems (VANETs), vehicles perform directing capacities, and in the meantime go about as end-frameworks subsequently steering control messages are transmitted unprotected over remote channels.
Scalability analysis of lter-based methods for feature selection

Researchers in machine learning are now interested not only in accuracy but also in scalability of methods. Although scalability of learning algorithms is a trending issue, scalability of feature selection methods has not received the same amount of attention. In this research, a preliminary attempt to study the scalability of three well-known filterbased feature selection methods will be done. For this sake, several new measures are introduced, based not only in accuracy but also in execution time and stability and the results will be presented according to them.
Union Wage Dispersion Magnitude and Trend Before and After the 2008 Financial Crisis

Over the past two decades the Canadian Labour market experienced a rise in the overall wage inequality and de-unionization. This paper provides empirical evidence on effects of unionization on the real hourly wage before and after the 2008 financial crisis in Canada. The Ordinary Least Square (OLS) model is used to estimate the impact of union status and time related (such as time trend, year, and post-2008) variables on the real hourly wage level. Moreover, Heckman’s twostep approach is performed to correct for non-random sample selection. The findings show unionization affects the real hourly wage positively, while the time variables’ coefficients indicate the 2008 financial crisis did not have a significant impact on the real hourly wage level in Canada.
Functional Fear and Public Insecurities About Crime

Fear of crime is widely seen as an unqualified social ill, yet might some level of emotional response comprise a natural defence against crime? Our methodology differentiates between a dysfunctional worry that erodes quality of life and a functional worry that motivates vigilance and routine precaution. A London-based survey shows that one-quarter of those individuals who said they were worried about crime also viewed their worry as something akin to a problem-solving activity: they took precautions; these precautions that made them feel safer; and neither the precautions nor the worries reduced the quality of their lives. Fear of crime can therefore be helpful as well as harmful: some people are both able and willing to convert their concerns into constructive action.
Title Circulating microRNA expression profile and systemic right ventricular function in adults after atrial switch operation for complete transposition of the great arteries

Background: Data on the use of circulating microRNAs (miRNAs) as biomarkers of cardiovascular diseases are emerging. Little, however, is known on the expression profile of circulating of microRNAs in congenital heart malformations with a systemic right ventricle that is prone to functional impairment. We aimed to test the hypothesis that circulating miRNA profile is altered in patients late after atrial switch operation for complete transposition of the great arteries (TGA) and further explored possible relationships between alteration of circulating miRNAs and systemic ventricular contractility. Methods: Circulating miRNA expression profiling of serum samples from 5 patients and 5 healthy controls was performed. The results were validated in 26 patients and 20 controls using real-time quantitative reverse-transcription polymerase chain reaction for candidate miRNAs with fold changes >3 by expression profiling. Systemic ventricular myocardial acceleration during isovolumic contraction (IVA) was determined by colour tissue Doppler echocardiography. Results: Compared with controls, patients had significantly lower systemic ventricular IVA (p = 0.002). Of the 23 upregulated miRNAs identified by profiling, 11 were validated to be increased in patients compared with controls: miR-16, miR-106a, miR-144*, miR-18a, miR-25, miR-451, miR-486-3p, miR-486-5p, miR-505*, let-7e and miR-93. Among the validated 11 miRNAs, miR-18a (r = −0.45, p = 0.002) and miR-486-5p (r = −0.35, p = 0.018) correlated negatively with systemic ventricular IVA for the whole cohort. Conclusions: A distinct serum miRNA expression signature exists in adults with complete TGA after atrial switch operation, with serum miR-18a and miR-486-5p being associated with systemic ventricular contractility.
Social context modulates basic properties of oculomotor control

Experiments performed in a lab are often considered generalizable over both people and social settings. The problems with generalizing over different groups of people are well known, but it is only recently that changes in behavior depending on the social setting have been examined. Large changes in behavior can be seen in trivial cognitive tasks, depending on whether the participant is alone or if other people are present. However, there are very few studies which have measured eye movements in social settings. In this paper, we used the antisaccade task to test whether basic parameters of oculomotor control are sensitive to the size of an experimental group. 70 participants conducted 48 antisaccade trials in groups of one to seven people in a classroom equipped with multiple eye trackers. The results show that for horizontal saccades, but not for vertical saccades, participants make significantly more antisaccade errors when the group size become larger. The group size did however not significantly predict a change in antisaccade latency. These results are in line with a number of recent studies on social attention showing that the mere presence of other people in the room can modulate several aspects of performance, and show that behavior in a lab might not be easily generalizable to everyday life or social situations. Finally, from a methodological viewpoint, the results show that the group size should be considered when testing participants in a social setting.
Improving skills for more and better jobs

I use data from the ECHP to assess the effects of adult training on individual labour market performance. Although I find that employee training has a clear impact on wage growth only in the case of young or highly educated employees, it appears to have a stronger impact on employment security in the case of both older and low-educated workers. The contradiction is only apparent since, as standard in the literature, training wage premia are estimated on a censored sample including only employed workers. Due to the existence of downward wage rigidity, one can expect that those workers who are unable to maintain their productivity (due, for instance, to skill obsolescence) are more frequently laid–off and thereby excluded from our sample. Once foregone income due to unemployment spells is taken into account, it can be concluded that training positively affects earnings at any age and level of educational attainment. In spite of these high ex post private return, pervasive market failures justify a pro-active approach to training policy. I argue that co-financing arrangements — under which governments, employers and/or employees jointly finance training — can better leverage the required resources to upgrade the competences of those in employment. Co-financing schemes, if carefully designed, seem to be potentially effective in reducing under-provision of training — both overall and for specific groups — in a way that minimises deadweight losses, although specific programmes for the unemployed or the inactive might require full government funding.
ISSUES RELATED TO THE NUMERICAL IMPLEMENTATION OF A SPARSE METHOD FOR THE SOLUTION OF VOLUME INTEGRAL EQUATIONS AT LOW FREQUENCIES

OF THESIS ISSUES RELATED TO THE NUMERICAL IMPLEMENTATION OF A SPARSE METHOD FOR THE SOLUTION OF VOLUME INTEGRAL EQUATIONS AT LOW FREQUENCIES Computational electromagnetic modeling involves generating system matrices by discretizing integral equations and solving the resulting system of linear equations. Many methods of solving the system of linear equations exist and one such method is the factorization of the matrix using the so called localglobal solution (LOGOS) modes. Computer codes to perform the discretization of the integral equations, filling of the matrix, and the subsequent LOGOS factorization have previously been developed by others. However, these codes are limited to complex double precision arithmetic only. This thesis extends and expands the existing computer by creating a more general implementation that is able to analyze a problem not only in complex double precision but also in real double precision and both complex and real single precision. The existing code is expanded using “templates” in Fortran 90 and the resulting generic code is used test the performance of the LOGOS (both OLand NL-LOGOS) factorization on matrices generated by discretization of the volume integral equation. As part of this effort, we demonstrate for the first time that the LOGOS factorization provides an O(N log N) complexity solution to the volume integral equation formulation of low-frequency electromagnetic problems.
Effects of Dietary Fat Supplementation on Reproduction in Lactating Dairy Cows

8 Improvement in fertility apart from improved energy status suggests that fat supplementation mediates it's positive effect through other physiological mechanisms such as : progesterone concentrations in plasma are enhanced by fat supplementation and may enhance embryo survival; certain Poly Unsaturated Fatty Acids (PUFA), such as linoleic acid and eicosapentanoic acids may reduce uterine secretion of PGF2α .
Global change effects on decomposition processes in tidal wetlands : implications from a global survey using standardized litter

Tidal wetlands, such as tidal marshes and mangroves, are hotspots for carbon sequestration. The preservation of organic matter (OM) is a critical process by which tidal wetlands exert influence over the global carbon cycle and at the same time gain elevation to keep pace with sea-level rise (SLR). The present study provides the first global-scale field-based experimental evidence of 50 temperature and relative sea level effects on the decomposition rate and stabilization of OM in tidal wetlands. The study was conducted in 26 marsh and mangrove sites across four continents, utilizing commercially available standardized OM. While effects on decomposition rate per se were minor, we show unanticipated and combined negative effects of temperature and relative sea level on OM stabilization. Across study sites, OM stabilization was 29% lower in low, more frequently flooded 55 vs. high, less frequently flooded zones. OM stabilization declined by ~90% over the studied temperature gradient from 10.9 to 28.5°C, corresponding to a decline of ~5% over a 1°Ctemperature increase. Additionally, data from the long-term ecological research site in Massachusetts, US show a pronounced reduction in OM stabilization by >70% in response to simulated coastal eutrophication, confirming the high sensitivity of OM stabilization to global 60 change. We therefore provide evidence that rising temperature, accelerated SLR, and coastal eutrophication may decrease the future capacity of tidal wetlands to sequester carbon by affecting the initial transformations of recent OM inputs to soil organic matter.
Production of Activated Carbon Electrodes from Sago Waste and its application for an Electrochemical Double-Layer Capacitor

Research on the utilization of sago waste as an activated carbon electrode for an electrochemical double-layer capacitor (EDLC) has been successfully performed. An important part of the EDLC is the highly porous activated carbon electrode that is prepared without the addition of adhesive materials with an optimum physical activation time. The sago waste-based activated carbon was prepared without adhesive materials with different physical activation times of 0.5, 1.0, 1.5, 2.0 and 2.5 hours. The effect of the physical activation time is discussed in terms of the physical and electrochemical properties of the carbon electrodes. The evaluated physical properties of the electrode include the density, surface morphology, chemical element content, degree of crystallinity and surface area. The electrochemical properties of the supercapacitor cells were studied for specific capacitances on a two-electrode system using the cyclic voltammetry method. The optimum specific capacitance of the sample electrode was 132 F g -1 , which was achieved with an activation time of 2.5 hours.
Budget Uncertainty and Faculty Contracts: A Dynamic Framework for Comparative Analysis

We study hiring decisions made by competing universities in a dynamic framework, focusing on the structure of university finance. Universities with annual state-approved financing underinvest in high-quality faculty, while universities that receive a significant part of their annual income from returns on endowments hire fewer but better faculty and provide long-term contracts. If university financing is linked to the number of students, there is additional pressure to hire low-quality short-term staff. An increase in the university’s budget might force the university to switch its priorities from ‘research’ to ‘teaching’ in equilibrium. We employ our model to discuss the necessity for state-financed endowments, and investigate the political economics of competition between universities, path-dependence in the development of the university system, and higher-education reform in emerging market economies.

Multi-Level Recursive Method of Short-Term Traffic Flow Forecast based on PGAGO GM (1, 1) Model

The prediction of short-term traffic flow has become one of the core researched content of ITS, and plays a key role in traffic management and control. Considering the concept of time varying parameters and the volatility of traffic flow data, multi-level recursive method based on PGAGO(Generalized Accumulated Generating Operation) GM (1,1) is adopted in this paper to improve the accuracy of the prediction and make the prediction model more tally with the actual situation. The forecast step is divided into two parts: the prediction of model parameters and traffic flow forecast based on the predicted values of the parameters. Results of example show that the combination of the two kinds of methods can not only improve the accuracy of the prediction, but also fit the situation that there are singular points in the parameter sequences. The introduction of PGAGO GM (1,1) model makes the model have more extensive applicability and practical meaning. Key words: Short-term traffic flow; Multi-level recursive method; PGAGO GM (1, 1); Grey prediction
Volatility Spillover from the Fear Index to Developed and Emerging Markets

ABSTRACT This article examines cross-market volatility linkages among the fear index (VIX), the developed-market index (VXEFA), and the emerging-market index (VXEEM). Analysis on the first moments of volatilities reveals that the fear index has a leading role and has information content for VXEFA and VXEEM. A shock to the fear index spillovers to VXEFA and VXEEM and contributes 57.07% and 63.77% to their shocks, respectively. Further analysis on the second moments of volatilities confirms that the volatility indices are highly dynamically correlated while the fear index drives the correlation dynamics with the VXEEM. Correlations increase in turbulent periods and decrease in tranquil periods.

Self-assembly and soft material preparation of binary organogels via aminobenzimidazole/benzothiazole and acids with different alkyl substituent chains

The gelation behaviors of binary organogels composed of aminobenzimidazole/benzothiazole derivatives and benzoic acid with single-/multialkyl substituent chain in various organic solvents were designed and investigated. Their gelation behaviors in 20 solvents were tested as new binary organic gelators. This showed that the number and length of alkyl substituent chains and benzimidazole/benzothiazole segment have played a crucial role in the gelation behavior of all gelator mixtures in various organic solvents. More alkyl chains in molecular skeletons in present gelators are favorable for the gelation of organic solvents. The length of alkyl substituent chains has also played an important role in changing the gelation behaviors and assembly states. Morphological studies revealed that the gelator molecules self-assemble into different aggregates from wrinkle, lamella, belt, to fiber with change of solvents. Spectral studies indicated that there existed different H-bond formation and hydrophobic force, depending on benzimidazole/benzothiazole segment and alkyl substituent chains in molecular skeletons. The prepared nanostructured materials have wide perspectives and many potential applications in nanoscience and material fields due to their scientific values. The present work may also give new clues for designing new binary organogelators and soft materials.

Dividend Policy, Corporate Control and Tax Clienteles The Case of Germany

This paper studies the impact of the concentration of control, the type of controlling shareholder and the dividend tax preference of the controlling shareholder on dividend policy for a panel of 220 German firms over 1984-2005. While the concentration of control does not have an effect on the dividend payout, there is strong evidence that the type of controlling shareholder matters as family controlled firms have high dividend payouts whereas bank controlled firms have low dividend payouts. However, there is no evidence that the dividend preference of the large shareholder has an impact on the dividend decision.
Frictional response of a thick gouge sample: 2. Friction law and implications for faults

[1] On the basis of experimental results, we propose a new friction law aiming at describing the mechanical behavior of thick gouge layers. As shown in the companion paper, the dominant effect to take into account is a significant slip-weakening process active over decimetric slip distances. This slip weakening is strongly nonlinear and, formerly, does not involve any characteristic length scale. The decrease of the gouge friction coefficient μ with imposed slip δ is well modeled by a power law: μ = μ0 + αδ−β, with β = 0.4. On this major trend are superimposed second-order velocity-weakening and time-strengthening effects. These effects can be described using classical rate- and state-dependent friction (RSF) laws and are associated with a small length scale dc ≈ 100 μm. Consistent with the general RSF framework, we combine slip-weakening and second-order effects in a slip, rate, and state (SRS) friction law with two state variables. We then compute the fracture (or breakdown) energy Gc and the apparent weakening distance Dcapp associated with the slip-weakening process. Once extrapolated to realistic “geophysical” confining pressures, the obtained values are in excellent agreement with those inferred from real earthquakes: Gc ≈ 5 × 106 J m−2 and Dcapp ≈ 20 cm. We also find that fracture energy scales with imposed slip in our experiments: Gc ∼ δ0. 6.
