Diversity of Social Wasps on Semideciduous Seasonal Forest Fragments with Different Surrounding Matrix in Brazil

We surveyed social wasps (Polistinae) present in forest fragments of northwest of Sao Paulo state with different surroundings composed of a matrix of citrus crops and sugarcane in the expectation that the former matrix would be more diverse than the latter. We collected specimens actively using attractive liquids. We obtained 20 species in Magda, 13 in Bebedouro, 13 in Matao, and 19 in Barretos. The most common genus was Agelaia in all of the areas. The greatest Shannon-Wiener index of diversity was obtained in Magda (H′=2.12). Species such as Brachygastra moebiana, Metapolybia docilis, Mischocyttarus ignotus, M. paulistanus and M. consimilis had not been recorded on recent surveys in the state. Furthermore M. consimilis is a new record for the state. We concluded that, with our data, a relation between the occurrence of social wasps and the surrounding matrix was not detected.
Some features of investing SMEs in Kosovo

Small and medium enterprises play an important role in the economic development of a country, especially for transition countries, since constitute the largest participative economic structure of these countries. Their role is crucial for these countries to resolve problems arising from the transformation process in these countries. Kosovo is a country that is in a process of late transition. Development of SMEs depends on their ability to grow and develop. This paper is based on data collected from surveys of SMEs by BSC Kosovo in late 2012 and aims to provide some features of the investing SMEs in Kosovo by observed them as a whole as well in particular by micro, small and medium category enterprises. The analysis has to do with the features that characterize SMEs which had investment activity. Our analysis suggests that investment as important variable SMEs had positive correlation with the size and age of the enterprise. Also investing SMEs are characterized by recruitment of new employees in the last year, having written a business plan and used of bank loans. SMEs that operate in two or more locations, as well as those with importing activity are characterized by the investment activities. Investments have no significant correlation with the sector in which the company operates, but generally dominate trade SME which dominate the economic structure in Kosovo. Investments of services enterprises have a downward trend with increasing the size of the company, while the manufacturing enterprises shows a positive trend in this regard, since their participation is increasing investment in enterprises with increasing the size of the enterprise.
STUDY OF ATTITUDES TOWARDS THE USE OF MOBILE PHONES WHILE DRIVING WITH IMPLICIT ASSOCIATION TESTS AND SELF-ASSESSMENT PROCEDURES

Analysis of studies shows that in studying attitudes towards risky and safe driving only few researches are based on the use of implicit methods. The aim of the study: the study of attitudes towards the use of mobile phones while driving with the use of Implicit Association Tests and self-assessment procedures. Participants: 69, age 21-59, M = 42, SD = 9.02, 27 female and 42 male, all with B category driver licenses, driving experience 9-24 years. Implicit measurements: two experimental procedures of the Implicit Association Test (IAT) developed by the authors for measuring attitudes towards the use of mobile phones while driving: IAT and self-concept IAT Explicit measurements: a self-assessment procedure developed by the authors “Scale of measuring attitudes towards the use of mobile phones while driving,” cross-cultural Personality Questionnaire ZKPQ-50-CC (Aluja, Rossier, García, Angleitner, Kuhlman, & Zuckerman, 2006). A positive relationship between the results of measurements using IAT and self-concept IAT was found in participants with high anxiety. The effect size obtained with the IAT is larger than the effect size obtained with self-concept IAT. A relationship between the results of measurement of attitudes towards the use a mobile phone while driving, measured by experimental procedures and the personal factors was found.
Compact Low Cost Passive RFID Tag for Object Tracking

RFID technology is a similar to barcode technology with the difference being that it does not require any clear line of sight condition for object detection. The chipless tag used in the RFID technology is aimed for reducing the cost. With an increase in the number of bit, the tag dimension as well as the cost also increases. A resonator based chipless tag is realized in this paper using spiral resonating structure for ultra-high frequency (UHF) of 2.6 GHz which is having stop band filter response. The realized tag is simulated and experimental results are analyzed to ensure the reliability of the proposed idea.
WEIGHTS OPTIMIZATION OF NEURAL NETWORK VIA IMPROVED BCO APPROACH

Feed forward neural Network (FNN) has been widely applied to many fields because of its ability to closely approximate unknown function to any degree of desired accuracy. Back Propagation (BP) is the most general learning algorithms, but is subject to local optimal convergence and poor performance even on simple problems when forecasting out of samples. Thus, we proposed an improved Bacterial Chemotaxis Optimization (BCO) approach as a possible alternative to the problematic BP algorithm, along with a novel adaptive search strategy to improve the efficiency of the traditional BCO. Taking the classical XOR problem and sinc function approximation as examples, comparisons were implemented. The results demonstrate that our algorithm is obviously superior in convergence rate and precision compared with other training algorithms, such as Genetic Algorithm (GA) and Taboo Search (TS).
Error propagation in geochemical modeling of trace elements in two-component mixing

En este trabajo se desarrollan las ecuaciones de propagacion de incertidumbres para un modelado geoquimico de elementos traza durante una mezcla de dos componentes o miembros terminales. Las ecuaciones proporcionan las incertidumbres resultantes en la concentracion de un elemento o la relacion de dos elementos en una mezcla de dos miembros, como funcion de las incertidumbres iniciales de medicion. Varios ejemplos ilustran el empleo de estas ecuaciones en el modelado geoquimico. Aunque, como esperado, la concentracion de un elemento o la relacion de dos elementos en la mezcla se encuentra siempre entre los valores correspondientes a los dos miembros, no es el caso para las incertidumbres correspondientes de medicion. La %Rsd (Desviacion estandar relativa expresada en %) de la concentracion de un elemento en la mezcla nunca es mayor de %Rsd del miembro con mayor incertidumbre para ese elemento, pero podria ser menor al miembro con menor incertidumbre. De la misma manera, la propagacion de incertidumbres con los datos de basaltos y sedimentos de la placa de Cocos proporciona ejemplos adicionales para el empleo de estas nuevas ecuaciones y su importancia en problemas petrogeneticos.
Munich Personal RePEc Archive Market Share Discounts and Investment Incentives

The paper investigates proand anticompetitive e¤ects of the use of market share discounts (MSDs). While MSDs can be used for exploiting a dominant position and may lead to a welfare reduction, MSDs also can serve as an e¢ cient device for the creation of incentives. Particularly, if a nal demand for an upstream manufacturers good depends on a promotional e¤ort of a retailer, the manufacturer can e¤ectively use MSDs to induce an optimal level of the retailers e¤ort. Moreover, it is possible that MSDs have a positive impact both on the consumerssurplus and the total industry pro ts. Thus the use of MSDs should not be treated as an anticompetitive practice a priori, but rather it has to be judged on a case-by-case basis. JEL classi cation: L22, L25, L42
FOD RESISTANCE AND FATIGUE CRACK ARREST IN LOW PLASTICITY BURNISHED IN718

Surface enhancement methods induce a layer of residual compressive stress to improve fatigue life. Shot peening is inexpensive and widely used, but the associated cold work accelerates relaxation of the compressive layer at turbine temperatures and increases sensitivity to overload relaxation. “Deep rolling” burnishing methods produce deep compression, but with cold work comparable to shot peening. Laser shock peening (LSP) produces deep compression with minimal cold work and impressive FOD resistance, but is costly and presents logistical problems in manufacturing. Low Plasticity Burnishing (LPB) has been investigated as a rapid, inexpensive surface enhancement method. Preliminary results indicate depth and magnitude of compression comparable to LSP. Compression reaching the alloy yield strength and extending to a depth of 1.2 mm (0.047 in.) is achievable with cold work of less than 4%. Excellent surface finish can be achieved with no detectable metallurgical damage. Ease of adaptation to CNC machine tools allows LPB processing at costs and speeds comparable to machining operations. The LPB process is described with application to IN718. Thermal stability at engine temperatures is compared to conventional shot peening. Resistance to 0.13 and 0.25 mm (0.005 and .010 in.) deep sharp notch FOD was achieved, even after exposure to engine temperatures. Elevated temperature crack growth data are presented showing the arrest of existing 0.46 mm x 0.91 mm (0.018 x 0. 036 in.) fatigue cracks by the deep compressive layer.
The Atmospheric Response to Surface Heating under Maximum Entropy Production

AbstractIn numerous studies, midlatitude storm tracks have been shown to shift poleward under global warming scenarios. Among the possible causes, changes in sea surface temperature (SST) have been shown to affect both the intensity and the position of the tracks. Increased SSTs can increase both the lateral heating occurring in the tropics and the midlatitude temperature gradients, both of which increase tropospheric baroclinicity.To better understand the response to altered SST, a simplified energy balance model (EBM) is used. This employs the principal of maximum entropy production (MEP) to determine the meridional heat fluxes in the atmosphere. The model is similar to one proposed by Paltridge (1975) but represents only the atmospheric response (the surface temperatures are fixed). The model is then compared with a full atmospheric general circulation model [Community Atmosphere Model, version 3 (CAM3)]. In response to perturbed surface temperatures, EBM exhibits similar changes in (vertically integrat.
Drought stress in tomato increase the performance of adapted and 2 non-adapted strains of Tetranychus urticae 3 4

12 The performance of the two-spotted spider mite, Tetranychus urticae Koch, on 13 plants depends on the rate of adaptation of mite populations to each particular host and 14 can be influenced by environmental conditions. We have tested the effects of drought 15 stress, caused by water deficiency, in the interaction of tomato plants with tomato 16 adapted (TA) and tomato non-adapted (TNA) strains of T. urticae. Our data revealed 17 that mite performance was enhanced for the TA strain when reared on drought-stressed 18 tomato plants, rising population growth and leaf damage. Population growth in the case 19 of the TNA strain was negative, but they laid more eggs and the number of mobile 20 forms was higher on drought stressed tomato plants than on control plants. Water stress 21 resulted in tomato plants with increased concentrations of essential amino acids and free 22 sugars, improving the nutritional value of drought-stressed tomato plants for T. urticae. 23 Mite infestation alone had almost no effect on the nutritional composition of tomato 24 leaves, with the exception of an increase of free sugars. Tomato plant defense proteins 25 were induced by both drought stress and mite infestation. However, the induction of 26 protease inhibitors was higher in tomatoes exposed to mites from the TNA strain than in 27 tomatoes that were fed upon by mites from the TA strain. The better performance of the 28 TA strain could be associated to both changes in the digestive (cysteine and aspartyl 29 protease and α-amylase activities) and detoxification (esterase activity) physiology of 30 the mites and the attenuation of some of the plant defenses (protease inhibitors). Taken 31 together, our results suggest that drought stress might favor outbreaks of T. urticae on 32 tomato, by enhancing population growth of adapted populations and increasing the 33 suitability of tomato as a host for non-adapted ones.
Designing A Distribution Emergency Information Service in Earthquake Post-Disaster Based on Service Computing System Engineering

The earthquake disaster has occurred in Indonesia. Earthquake disaster resulted in heavy casualties, property losses, and loss of municipal infrastructure. Disaster mitigation efforts after earthquake events are needed to reduce the number of fatalities. This paper aims to design the distribution emergency information application in earthquake post-disaster in Meteorological, Climatological, and Geophysical Agency (BMKG). This application is useful to minimize the number of earthquake disaster victims, which makes it easier for the rescue squads to track the whereabouts of victims. Utilizes Internet of Things (IoT) technology in post-disaster management can solve that problems, where the smartphone can be used as a coordinate sensor for the victim. Therefore Service Computing System Engineering (SCSE) is used in the design. The proposed design is then measured based on SOA principles, coupling, cohesion, complexity, and reusability. After measuring the evaluation of the design, it has been verified that the design could pursue the next step of the engineering process.
Direction-of-Arrival Estimation Based on Deep Neural Networks With Robustness to Array Imperfections

Lacking of adaptation to various array imperfections is an open problem for most high-precision direction-of-arrival (DOA) estimation methods. Machine learning-based methods are data-driven, they do not rely on prior assumptions about array geometries, and are expected to adapt better to array imperfections when compared with model-based counterparts. This paper introduces a framework of the deep neural network to address the DOA estimation problem, so as to obtain good adaptation to array imperfections and enhanced generalization to unseen scenarios. The framework consists of a multitask autoencoder and a series of parallel multilayer classifiers. The autoencoder acts like a group of spatial filters, it decomposes the input into multiple components in different spatial subregions. These components thus have more concentrated distributions than the original input, which helps to reduce the burden of generalization for subsequent DOA estimation classifiers. The classifiers follow a one-versus-all classification guideline to determine if there are signal components near preseted directional grids, and the classification results are concatenated to reconstruct a spatial spectrum and estimate signal directions. Simulations are carried out to show that the proposed method performs satisfyingly in both generalization and imperfection adaptation.
FourWeeks of Inspiratory Muscle Training Improves Self-PacedWalking Performance in Overweight and Obese Adults : A Randomised Controlled Trial

Objective. To examine whether a programme of inspiratory muscle training (IMT) improves accumulative distance of self-paced walking in overweight and obese adults. Methods. A total of 15 overweight and obese adults were randomized into experimental (EXP: n = 8) and placebo (PLA: n = 7) groups. Lung function, inspiratory muscle performance, 6-minute walking test, and predicted V̇O2 max were assessed prior to and following the 4-week IMT intervention. Both groups performed 30 inspiratory breaths, twice daily using a proprietary inspiratory resistance device set to 55% of baseline maximal effort (EXP), or performing the same inspiratory training procedure at the minimum resistive setting (PLA). Results. Lung function was unchanged in both groups after-training; however inspiratory muscle strength was significantly improved in EXP (19 ± 25.2 cm H2O gain; P < 0.01) but did not significantly change in PLA. Additionally, the posttraining distance covered in the 6-minute walking test was significantly extended for EXP (62.5 ± 37.7 m gain; P < 0.01), but not for PLA. A positive association was observed between the change (%) of performance gain in the 6-minute walking test and body mass index (r = 0.736; P < 0.05) for EXP. Conclusion. The present study suggests that IMT provides a practical, minimally intrusive intervention to significantly augment both inspiratory muscle performance and walking distance covered by overweight and obese adults in a clinically relevant 6-minute walk test. This indicates that IMT may provide a useful priming (preparatory) strategy prior to entry in a physical training programme for overweight and obese adults.
BIT ERROR RATE REDUCTION FOR MULTIUSERS BY SMART UWB ANTENNA ARRAY

In this paper, a new ultra wideband circular antenna array (UCAA) combining genetic algorithm (GA) to minimize the bit error rate (BER) is proposed. The ultra wideband (UWB) impulse responses of the indoor channel for any transmitter-receiver location are computed by SBR/Image techniques, inverse fast Fourier transform and Hermitian processing. By using the impulse response of multipath channel, the BER performance of the binary pulse amplitude modulation (B-PAM) impulse radio (IR) UWB system with circular antenna array can be calculated. Based on the topography of the antenna and the BER formula, the array pattern synthesis problem can be reformulated into an optimization problem and solved by the genetic algorithm. The novelties of our approach is not only choosing BER as the object function instead of sidelobe level of the antenna pattern, but also considering the antenna feed length efiect of each array element. The strong point of the genetic algorithm is that, it can flnd out the solution even if the performance index cannot be formulated by simple equations. Simulation results show that the synthesized antenna array pattern is efiective to focus maximum gain to the multiusers.
Effect of Ensiling Graded Level of Poultry Litter with Desho Grass (Pennisetum pedicellatum) on Palatability and Nutritional Characteristics of Silage in Case of Bonga Sheep

In tropical region inadequate quality and quantity of feed are major constraints to livestock production sector. Most of feed resources are low in nutrient content to meet nutrient requirement of maintenance, production and reproduction. Therefore this study was carried out to evaluate the effect of ensiling graded level of poultry litter with desho grass (Pennisetum pedicellatum) on intake, preference, fermentative and nutritional characteristics of silage in case of Bonga Sheep . Poultry litter (Pl) and desho grass (Dg) was ensiled by four treatments; T1 (100%Dg), T2(80%Dg+20%Pl), T3(70%Dg+30%Pl) and T4(60%Dg+40%Pl) in three replications for 30 days. Ten Bonga sheep were used to evaluate the free choice intake of silage in a cafeteria style. The experimental design was complete randomized design (CRD). Data obtained were subjected to analysis of variance and significant means. Ensiling with poultry litter significantly (P T2> T1 > T4. It is concluded that desho grass ensiled within 20% to 30% poultry litter improved Crude protein (CP) content and intake by Bonga sheep when compared with control and 40% poultry level. Keywords: silage, poultry litter, desho grass, palatability trail, Bonga, sheep
Analysis of Load Match in Nearly Zero Energy Buildings

The concept of load matching refers to the degree of agreement or disagreement of the on-site generation with the building load profiles: it can be increased and optimised with modifications on both the energy demand and generation. In this context, the paper presents the load match analysis of a case study: a modular housing construction (it has an area of 45 m2 and S/V ratio equal to 2.75 m−1) built in Messina (Italy). Moreover, in order to optimize the design of the next test module to be built, a parametric analysis was performed considering different scenarios on the generation side, to explore the effectiveness of the solutions sets used in current design and plan different solutions for the future ones. The results show that a 4 kWh energy storage system can increase the load cover factor by 94% (to 0.78) compared to the base case (0.41), while with only a 250 W fuel cell, the load cover factor can reach the value of 0.97.
English Teacher – Educators’ Approaches and Practices: A Case Study in Three Different Contexts

The present article drew on a larger interpretivist case study research on the knowledge, beliefs, approaches and practices of the language teacher educator in three different contexts. It was constructed with the participation of seven educators of teachers of English as a foreign language. Four of them worked in two different Mexican universities which were in distinct parts of the country, and three educators worked for a Spanish university; all of them taught theoretical and practical courses of an English language teaching program. The purpose of this article is to raise awareness of the similarities and differences in the approaches and practices developed by the language teacher–educators. Questionnaires, observations, interviews and video recordings were the methods used for the collection of the data. The case study shows that, according to the participants’ opinions, the teacher -educators tend to a learning centred approach in Mexico whereas the teacher educators in Spain combine teaching strategies of both approaches: Content centred approach and learning centred approach. Nevertheless, the teaching practices of all the case study teacher educators are similar despite the differences of contexts, and they are mainly representative of the Learning-focused approach to teaching.
