Flow and Sediment Transport on a Tidal Salt Marsh Surface

Abstract The physical processes that control mineral sediment deposition on a mesotidal salt marsh surface on the Atlantic Coast of Virginia were characterized through a series of measurements of sediment concentration, flow velocity, turbulence, water surface elevation, marsh topography and particle size distributions of sediment deposited on the marsh surface. The comprehensive nature of the data set allowed assessment of the temporal and spatial variability in marsh surface deposition, the variability in depositional processes among tides of different amplitudes, as well as the specific processes that control deposition on this tidal marsh. Through three different types of measurements, it was found that sediment deposition occurred on the marsh surface during rising tides at tidal elevations ranging from those barely flooding the creek bank to high spring tides, and that sediment was not remobilized by tidal flows after initial deposition. Sediment deposition occurred on this marsh surface largely because fine sediment in suspension formed flocs. Analysis of inorganic grain size distributions of sediment deposited within 8 m of the tidal creek indicated that 70–80% of this sediment was deposited in a flocculated form. The rest (particles larger than 20 μm) were deposited as individual particles. In the marsh interior, 25 m from the tidal creek, single grain settling predominated. Reduction of turbulence levels within the vegetation canopy on the marsh also promoted particle settling. The processes controlling sediment deposition did not vary among tides. However, suspended sediment concentrations near the creek bank increased with increasing tidal amplitude, consequently promoting higher rates of deposition on higher tides.
Trade Elasticity, Gravity and The Gains from Trade: Evidence from the Food Industry

This paper estimates the elasticity of trade flows to trade barriers from gravity equations, using different econometric methods, with the aims to simulate the trade gains from the elimination of tariffs. Specifically, we compare a benchmark OLS fixed effects specification with three emerging estimation methods: the Heckman correction for selection bias; the Eaton and Tamura Tobit estimator, to solve limited-dependent variable issues; and, finally, the Poisson pseudomaximum-likelihood (PPML) technique, to correct for the presence of heteroskedasticity. The paper achieves two goals. First it provides estimates of the trade elasticity for eighteen food industries. Second, it gives a dimension to the trade reduction effect induced by existing border protection, by simulating the effects of a full trade liberalization scenario, computing the standard errors of predicted values. The estimates reveal interesting variations in the elasticity of substitution across products and procedures. The simulation indicates that trade liberalization will strongly increase agro-food trade, especially from high income and emerging countries.
Evolutive Optimization of Wavelets and Shapelets for Bioelectrical Signal Analysis

Wavelet analysis is a powerful tool for digital signal processing. It has been widely used in bioelectric signals including evoke-related potentials (ERP), electromyography signals (EMG), microelectrode recordings (MER), electrocardiogram (ECG), electroencephalograms (EEG), among others. Some of the principal advantages of wavelet transform are the compact support, and energy concentration. Basically, the wavelet transform is a convolution of the input signal with scaled and translated versions of one function called wavelet mother. Although there are plenty of wavelet prototypes in the literature, there is not an established rule that states which wavelet may be used for each application. Instead of that, it is a usual task for the researcher to test more o less arbitrarily different wavelet shapes in order to find one suited. In this manuscript the capabilities of the lifting schemes, which are a technique for both designing wavelets and performing the discrete wavelet transform and genetic algorithms are extended for wavelet synthesis in two scenarios: the signal–dependent filter bank and the discrete lifting shapelet transform. The former is an evolutionary method based on LS that aims at the synthesis of mother wavelets that exhibit unique time–frequency properties. Furthermore, the designed wavelet function is supposed to exhibit feature spaces with maximum class separability due to the employment of the clustering validation metrics as fitness function into the GA procedure. Results presented in three scenarios render the success of the proposed methodology including the identification of basal ganglia by means of microelectrode recording analysis, the recognition of hand movement using electromyographic signals, and the classification of epileptic seizures employing EEG signals.
Clientelism as Persuasion-Buying

In distributing clientelistic payoffs to citizens, the best strategy a party machine can pursue, we argue, is to target citizens who are opinion-leading epicenters in informal conversation networks. This persuasion-buying strategy carries the highest potential yield for the party because the payoff can create a social multiplier: The effect of the clientelistic gift can be magnified via the conversion of multiple voters within a payoff recipient’s personal networks. Using cross-sectional survey data from 22 Latin American countries and a panel survey from Mexico, we confirm that individuals who engage in frequent political persuasion and who are located in large political discussion networks are the most likely recipients of clientelistic payoffs. We also show that a finding that is key to previous theories, namely, that loyal partisans are the most likely targets of clientelism, is driven by omitted-variable and endogeneity bias.
Case Study of Internationalization Strategy of Cord Set Industry in Taiwan

The present study mainly investigated the internationalization strategy of case company in Taiwan cord set industry. The characteristics of this industry are low gross profit rate, many competitors, and high customer overlap. Thus, the companies need to have considerable economies of scale and productivity in order to competitive in the global market. Besides, the academic research about the internationalization strategy of this traditional manufacturing industry is lack. The results of present study not only can provide the proper internationalization strategy direction of case company, but also can provide reference to other companies in Taiwan cord set industry. Results showed the internationalization courses of case company are: (1) Joint venture and sole proprietorship are the main types of case company to setup overseas subsidiaries; (2) The purpose of difference areas is different: the subsidiaries of mainland China is followed customer and the Southeast Asia is expansion growth; (3) The internationalization strategy of case company is mainly followed the international leading company and pursuit of growth in current stage; (4) The strategy of cord set industry in Taiwan should be strategic alliance and diversification of products in the future.

Liquid crystal micro-lenticular array assembled by a fringing field

Based on dielectrophoretic effect, the phase separation morphology of liquid crystal (LC) in a liquid monomer can be manipulated by a fringing field. Applying the fringing field generated from interdigitated electrode upon the LC/monomer mixture, the randomly dispersed LC droplets can be assembled to grating-like stripes. When the field is removed, the LC stripes break into tiny droplets again. This process is reversible and stable. Our results show that the surface profile of each LC stripe exhibits a lenticular shape. The response time of the LC morphology converting from droplets to stripes and from stripes to droplets is ~0.96 s. Potential applications of this controllable morphology can be found in optical communications, beam steering, imaging, and displays.
Price-quality Dimensions of Organizational Buying Behaviour in Cross River State, Nigeria

This study examined the roles of price differentials offered by industrial goods vendors and quality specifications for industrial products in determining organizational buyer decision to patronize one vendor rather than another. Using survey data generated from 321 respondents in the three categories of business consumers in the Southern Senatorial district of Cross River State, our hypotheses were supported. Results of data analysis show that price differentials and quality requirements for industrial product significantly influence organizational buying behaviour. Our findings also suggest that because price differential are perceived by the customers as a gauge of value and quality, marketing managers of industrial goods and services stand to gain more by adopting strategies which give special attention to the ways buyers trade-off costs and benefits of various products.
Numerical simulation of the flow of wet granular materials

Nous etudions par simulation numerique discrete (DEM) le comportement d’assemblages de billes spheriques en ecoulement de cisaillement a contrainte normale P controlee, en presence de forces capillaires creees par une faible quantite de fluide intertitiel, sous forme de menisques joignant les grains voisins (etat pendulaire). Nous portons une attention particuliere a l’approche de la limite quasi-statique et caracterisons le comportement du materiau en exprimant le coefficient de frottement interne et la densite en fonction de deux parameters de controle sans dimension, le nombre d’inertie I et la pression reduite P* (qui compare les forces de confinement et la resistance a la traction d’un menisque). Les forces capillaires ont un effet notable sur la rheologie jusqu’a des valeurs de P* de plusieurs unites, particulierement dans le cas de force attractives a plus longue portee, pour les volumes de menisques plus importants. Cet effet est relie a l’anisotropie de la texture du reseau des contacts et des interactions a courte distance.
Single-Phase Single-Stage AC-DC Converter with Reduced Line-Current Harmonics

The circuit topology for a single-phase single stage ac-dc converter with the aim of minimising the converter’s line current harmonics is presented. The circuit is based on the halfcontrolled ac-dc converter topology and employs active switching devices to achieve its objective. These devices are used to provide alternative paths for the line current during periods when the smoothing capacitor is supplying the load current, thus reducing the line current harmonics. Extensive simulation studies have been carried out on the circuit and results are presented and compared with the results obtained from a standard ac-dc uncontrolled converter operating under similar conditions. The results indicate that the line current harmonics are reduced to levels compliant with those set out by the relevant European Union’s Directive, IEC61000-3-2, on harmonics injection into the supply mains directed at equipment that draws current 16 A ≤ .
Stored Energy Predictions from Dislocation-Based Hardening Models and Hardness Measurements for Tensile-Deformed Commercial Purity Copper

Stored energy analyses by differential scanning calorimetry (DSC) and indentation hardness measurement were performed on crosssectional samples cut from the gauge length of tensile-deformed copper specimens. The stress-strain curve was described using dislocationbased hardening models integrated into a visco-plastic Taylor-type model of polycrystal deformation. Three approaches in reproducing the experimental stress-strain curve were used to evaluate the differences in dislocation density predictions resulting from different modelling options. A good description of hardening was achieved by all three approaches and constitutive models and only negligible differences were found in the predicted dislocation density between assumed homogeneous and heterogeneous dislocation distribution throughout the polycrystal. Measured values of stored energy are somewhat lower than those published in research studies in which one-step and slow annealing methods were used. A simple model predicting a nearly linear increase of stored energy with dislocation density was found to adequately describe retained energy evolution. Since different dislocation arrangements result in different yield stress and energy predictions, both results can be used to determine values of parameters in two-internal-variable hardening models. Even though both measured quantities were satisfyingly described, uncertainties regarding material parameters and the applied polycrystal and stored energy models prevent us from claiming that the evaluated dislocation density distributions represent the actual dislocation structure in the material. As expected for strongly hardening materials, the relationship between yield stress and hardness could not be adequately approximated by a linear function. Instead, a linear combination of yield stress and hardening rate was used, finally providing a relation between hardness and stored energy through their mutual dependence on yield stress.
The impact of Acceptance of Leader criteria on Instructional Leadership

There are different criteria that may affect active leadership concepts that enhance the role of a principal as an instructional leader. However, many principals lack such criteria where a strong principal can be considered as an instructional leader. To become instructional leaders, principals must functional role directed toward teacher's productive collaboration relationship. Furthermore, a school principal as a leader should play an important role in enhancing teachersâ€™ satisfaction . This study aims to investigate the impact of acceptance of leader on instructional leadership. In doing so, the paper presents a conceptual model linking the acceptance of leader on instructional leadership. The study reports the findings from mix methods a survey of 536 participants including teachers, principals and senior chiefs at various levels of primary, elementary and secondary schools across Kingdom of Bahrain. And focus group method include six senior chiefs. The analysis of the results shows positive relationship between acceptance of leader and instructional leaders. More specifically, acceptance of leaders is influenced by the referent power. The findings show that there is a significant difference between principalsâ€™, teachersâ€™, and senior chiefsâ€™ perceptions on the effectiveness of acceptance of leader on instructional leadership.Keyword: Instructional leadership, acceptance of leader, referent power
IS/IT capability and Strategic Information System Planning (SISP) Success

[Abstract] Strategic planning of information systems is, perhaps, going to be more problematic in today’s world of rapid change and uncertainty. SISP is a cornerstone of the information system discipline, and very little attention has been paid to its success based on the resource-based view of the firm (RBV). This paper provides a model for IT capability and strategic information system planning success by considering environmental and organizational factors that may influence this relationship in a contingency model. A review of existing IT capability and SISP literature is given to identify the opportunities in building successful SISP. A model is developed by hypothesizing the IT capability, as independent variables lead to SISP success as a dependent variable in which organizational and environmental influences are considered as moderating variables. The control variables are firm size, firm structure, and industry type. The study proposes a model to conceptualize the relationship between IT capabilities and SISP success and contingency factors moderating that relationship. This paper explains the ways of exploiting IT capabilities as specialized and integrated knowledge of the firm in IT area to create a more successful SISP. The researchers believe that the aim to build a model for SISP success based on RBV theory is important because this new perspective will be helpful for gaining a superior assessment and better underpinning of the SISP from a knowledge-based perspective.
Fix Success and Accuracy of Global Positioning System Collars in Old-Growth Temperate Coniferous Forests

Abstract Global Positioning System (GPS) telemetry is used extensively to study animal distribution and resource selection patterns but is susceptible to biases resulting from data omission and spatial inaccuracies. These data errors may cause misinterpretation of wildlife habitat selection or spatial use patterns. We used both stationary test collars and collared free-ranging American black bears (Ursus americanus) to quantify systemic data loss and location error of GPS telemetry in mountainous, old-growth temperate forests of Olympic National Park, Washington, USA. We developed predictive models of environmental factors that influence the probability of obtaining GPS locations and evaluated the ability of weighting factors derived from these models to mitigate data omission biases from collared bears. We also examined the effects of microhabitat on collar fix success rate and examined collar accuracy as related to elevation changes between successive fixes. The probability of collars successfully obtaining location fixes was positively associated with elevation and unobstructed satellite view and was negatively affected by the interaction of overstory canopy and satellite view. Test collars were 33% more successful at acquiring fixes than those on bears. Fix success rates of collared bears varied seasonally and diurnally. Application of weighting factors to individual collared bear fixes recouped only 6% of lost data and failed to reduce seasonal or diurnal variation in fix success, suggesting that variables not included in our model contributed to data loss. Test collars placed to mimic bear bedding sites received 16% fewer fixes than randomly placed collars, indicating that microhabitat selection may contribute to data loss for wildlife equipped with GPS collars. Horizontal collar errors of >800 m occurred when elevation changes between successive fixes were >400 m. We conclude that significant limitations remain in accounting for data loss and error inherent in using GPS telemetry in coniferous forest ecosystems and that, at present, resource selection patterns of large mammals derived from GPS telemetry should be interpreted cautiously.
Chapter 2 STATISTICAL PROPERTIES OF SOCIAL NETWORKS

In this chapter we describe patterns that occur in the structure of social networks, represented as graphs. We describe two main classes of properties, static properties, or properties describing the structure of snapshots of graphs; and dynamic properties, properties describing how the structure evolves over time. These properties may be for unweighted or weighted graphs, where weights may represent multi-edges (e.g. multiple phone calls from one person to another), or edge weights (e.g. monetary amounts between a donor and a recipient in a political donation network).
The Impact of Exchange Rate Volatility on International Trade: Evidence from the MINT Economies

This paper examines the effect of exchange rate volatility on international trade activities for Mexico, Indonesia, Nigeria, and Turkey. We use volatility predicted from GARCH models for both nominal and real effective exchange rate data. To detect the long term relationship we use the autoregressive distributed lag (ARDL) bound testing approach; while for the short term effects, Granger causality models are employed. The results show that, in long term, there is no linkage between exchange rate volatility and international trade activities except for Turkey and even in this case the magnitude of the effect of volatility is quite small. In the short term, however, a significant causal relationship from volatility to import/export demand is detected for Indonesia and Mexico. In the case of Nigeria unidirectional causality from export demand to volatility is found, while for Turkey no causality between volatility and import/export demand is detected.
ANTECEDENTS OF DRIVERS OF SATISFACTION IN HOTEL INDUSTRY AND ITS IMPACT ON CUSTOMER LOYALTY

Services have a major impact on National economies and have become more competitive nowadays. In the buying process for services, quality is much more difficult to access prior to purchase. Hence consumers mostly try to perceive the quality based on the price and presentation of the service provider. Especially in the hotel industry, customer satisfaction comprises of both price satisfaction and service satisfaction. To increase the customer loyalty, customer satisfaction should be the topmost priority. In the paper the researcher tries to find out the impact of price satisfaction and service satisfaction on customer loyalty. Five dimensions of services are taken to see their impact on price and service satisfaction. The impact of price and service satisfaction on customer loyalty are then finally measured. A survey was done to measure the responses of the respondents about their opinion on the dimensions of services viz. satisfaction in reception, satisfaction in friendliness and service, satisfaction in room service, satisfaction in restaurant and breakfast and satisfaction in wellness area. Responses were also measured for price and service satisfaction and customer loyalty. A structured questionnaire was used to measure the responses of the respondents on a five point Likert’s scale. The findings show that the five dimensions of services have an impact on price and service satisfaction. Price and service satisfaction has an impact on customer loyalty.
Effect of Legal Sanction for Shareholders’ Expropriation on the Corporate Valuation

The purpose of this paper is to study whether the legal sanction by relevant departments for the majority shareholders’ expropriation affects the valuation of the firms’ or other shareholders’ interests. This study takes the legal sanction by relevant departments for the majority shareholders’ expropriation as external legal environment change events, so whether the return of the listed company shows significant difference during the window before and after the listed company has been sanctioned by the relevant departments for the majority shareholders’ expropriation will be the judgment whether the sanction has any obvious effect on the listed company and the stock market. The study demonstrates that almost all empirical results show that the positive and negative effects don’t pass the significance test, illustrating that the legal sanction system just has limited effect on the corporate governance of the listed company.
