Entrepreneurial Passion and Intention: Creativity and Perceived Behavioral Control as Mediators

Entrepreneurial passion is an attribute of an entrepreneur that influences a lot of entrepreneurial actions. This study considered perceived behavioral control and passion of an entrepreneur for the determination of intentions of entrepreneurs; alongside entrepreneurial creativity was considered in the study to explain the relationship of passion and intention. It was a quantitative study whose results indicate positive but indirect connection among passion and intention of an entrepreneur through perceived behavioral control and also insignificant mediating relation of entrepreneurial creativity.
Effect of Control on the Mathematical Model of Hepatitis B Virus with Infective Migrant

The transmission dynamics of Hepatitis B Virus in a population with infective immigrant is presented with the inclusion of an optimal control strategy to curtail the spread of the virus. To understand the spread of this infection, we develop a mathematical model with control variables of migrant screening and public sensitization. The optimality system is characterized using Pontryagin’s maximum principle and solve numerically with an implicit finite difference method. Result of the numerical simulation is presented to illustrate the feasibility of this control strategy. The analysis reveals that combination of both control variables could be the most fruitful way to reduce the incidence of Hepatitis B virus.

Learning to solve multi-robot scheduling: mean-ﬁeld inference theory for random GNN embedding and scalable auction with provable guarantee

We develop a theory for embedding a random graph using graph neural networks (GNN) and apply it to address the challenge of developing a near-optimal learning algorithm to solve the NP-hard problem of scheduling multiple robots with time-varying rewards. In particular, we consider a class of reward collection problems called Multi-Robot Reward Collection (MRRC). Such MRRC problems well model ride-sharing, pickup-and-delivery, and a variety of related problems. Our theory enables a two-step hierarchical inference for precise and transferable Q-function estimation for MRRC. For scalable computation, we show that the transferability of Q-function estimation enables us to design a polynomial-time algorithm with 1 − 1 /e optimality bound. Experimental results on solving NP-hard MRRC problems highlight the near-optimality and transferability of the method.
Role of Remifentanil in prevention increase of intraocular pressure after endotracheal intubation under Succinylcholine chloride

Objective: To evaluate the role of remifentanil in decreasing intraocular pressure (IOP) after endotracheal (ET) intubation under the effect of Succinylcholine (rapid sequence induction). Methods: a prospective, randomized double-blinded clinical trial, done on 36 patients who had elective surgery in the ophthalmology department, we had studied the changes in IOP after succinylcholine injection and tracheal intubation 3 different times, by dividing patients into two groups, group R who takes Remifentanil 1 μg/kg and propofol 2 mg/kg induction, and group C who received 5 ml normal saline with propofol 2mg/kg induction. Results: Patients respond well, IOP had been decreased significantly in the remifentanil group, p-value between the two groups were less than 0.05. Conclusions: Remifentanil has a significant effect on decreasing IOP in rapid sequence induction and ET intubation.
DIFFERENCES IN ESTIMATING FUTURE FERTILITY OF THE CZECH REPUBLIC USING VARIOUS STATISTICAL MODELS

The fertility of women in the Czech Republic underwent significant changes after the change of political regime in the 1990s. First, there was a decline in fertility in the 1990s and in the turn of the millennium. Subsequently, in recent years fertility has started to increase again a little. Women, however, acquire children at a higher age than in the past. The aim of the paper is to carry out projections of age-specific fertility rates using various statistical models to indicate possible future development of these rates. Thanks to this projection it is possible to observe whether current trends would manifest themselves, for example, in further postponement of fertility to older age or in further improvement of the overall fertility level. Both parametric and non-parametric models can be used for these statistical projections. The results show that projections vary greatly according to by which model age specific fertility rates are estimated, depending on how flexible each model is and which recent changes it takes most into account. Thus, in the case of the Czech Republic and its irregular development of age-specific fertility rates, these models may rather serve only as a basis for demographers in compiling population forecasts.
Subitizing as pattern recognition: evidence for automaticity

Subitizing allows detecting the quantity of a small set of elements (up to four) with the accuracy of counting and the velocity of estimation. Recent studies have supported a theory which considers subitizing as a visual mechanism of pattern recognition, sensitive to spatial disposition of elements. These studies have found an increase in response rate and accuracy in the assessment of quantity when elements to be enumerated are arranged in an orderly fashion. Whether the numerosity of orderly arranged elements is accessed automatically, without the requirement of attentional resources, is a relevant issue not yet empirically investigated. The current study investigated the relation between subitizing and automaticity in a target detection task where distractors were non-symbolic number stimuli (dot patterns), with two different arrangements, random or canonical (like dice faces), having the same or different numerosity in the number target. We found that with canonical patterns, in the subitizing range, response times were faster in compatible trials, and slower in incompatible trials, compared to random patterns which did not influence response times in any condition. This result revealed that when elements in a visual display form easily recognizable patterns, their numerosity is accessed automatically.
Influence of soil-drying under field conditions on exchangeable manganese, cobalt, and copper contents

Abstract The changes in the exchangeable Mn (Ex-Mn), exchangeable Co (Ex-Co), and exchangeable Cu (Ex-Cu) contents by air-drying of soils were reported in our previous paper. The drying effect, however, was not analyzed in the field. The objective of this study was to investigate the influence of soil-drying under field conditions on Ex-Mn, Ex-Co, and Ex-Cu levels. Two paddy soils (Tsukuba and Yawara) were collected at four different soil depths (0∓1, 1∓5, 5∓10, and 10∓20 cm) under three different soil moisture conditions i.e., after harvest, after successive sunny days and after rainy days. After sunny days, Ex-Mn and Ex-Co contents in the surface soil layer markedly increased and drastically decreased after rainfall, while they remained almost unchanged in the lower soil layers. Ex-Cu contents slightly increased in the surface soil layer after sunny days. A similar tendency was observed in soil column experiments. The contents of Ex-Mn, Ex-Co, and Ex-Cu increased 12, 12, and 2 times in the upper layer of soil columns that had been sampled from the Yawara field and stored in a dark room for 8 d. The increase of the Ex-Mn and Ex-Co contents in the upper layer could not be explained by the capillary rise of soil water from the lower layers of the columns. In a soil-drying experiment under laboratory conditions, Ex-Mn and Ex-Co contents began to increase when the water content of the Yawara soil was lower than 0.09∓0.13 kg kg−1. The water content of the surface soil of the Yawara field after sunny days was 0.08 kg kg−1. Ex-Cu content did not change apprecially with the water content. It is concluded that the increase of the Ex-Mn and Ex-Co levels in field surface soils after sunny days can be ascribed to soil-drying. Some of the excess Ex-Mn and Ex-Co is expected to leach down into lower layers due to rain, which may contribute to plant uptake of Mn and Co.
On Categories of Mathematics Teachers’ Classroom Characteristics and Perceived Influence on Effective Mathematics Teaching in Secondary Schools in Plateau State, Nigeria

In this paper, the categories and influence of teachers’ classroom characteristics relative to effective mathematics teaching in secondary schools in Plateau state, Nigeria were examined. The aim was to see how students are assisted to learn mathematics from teachers engaging fully their professional practices fully. Exploratory and descriptive survey research methods were used to examine the trajectories. Sample for the study consisted of 60 trained mathematics teachers from secondary schools in Plateau state that participated in a week-long capacity building workshop on teaching new concepts from secondary school mathematics curriculum in Nigeria organized recently by the state chapter of the Mathematics Association of Nigeria. Purposive sampling technique was used to select the sample based on the fact that the study targeted only mathematics teachers that participated in the capacity building workshop. A 52-item TCCQ on teacher effectiveness, interest, rapport with students, etc. was used for data collection. The findings from the study revealed that mathematics teachers’ ability to teach effectively is significantly associated with many factors including the use of different strategies (χ2=52.75), revision (χ2=47.13), good lesson plans (χ2=53.93) and being friendly with students (χ2=35.66). There was no significant variation regarding how the characteristics influence teacher effectiveness based on qualification (F2, 58=0.689). Among other things, therefore, it was recommended that teachers should be committed to teaching mathematics effectively in the classroom by taking cognizance of the variables especially designing of good lesson plans and previous knowledge irrespective of their qualifications.
Organizational Drivers of Innovation Deployment Process affecting the Marketing/Sales Interface The Case of Six Latin American Countries

This study investigates the antecedents of information management and its effect on formalization and joint planning as drivers of the marketing/sales perceived relationship effectiveness during the formalized process of new product deployment (NPD). We examine the effect of communication as perceived by the marketing and sales functions based on two components: communication amount/frequency and communication quality. Finally, we investigate how process formalization and joint planning affect the perceived relationship effectiveness of marketing and sales during NPD process. The study uses 152 matched responses from top level managers, responsible for the innovation deployment of six South American subsidiaries of a consumer packaged goods company. The studied firm is ranked within the 50 most admired companies (Fortune 2012) whose product innovation account for more than 70% sales growth. Empirical results show that communication dimensions influence the perceived effectiveness of marketing/sales relationships during the innovation deployment. The amount of shared communication and its quality also enhance the positive effect of joint planning on this variable, but only the frequency of communication affects process formalization. In addition, the findings suggest that Stage-Gate formalization has no significant (negative) effect on the perceived cross functional relationship. Whilst numerous studies have researched the drivers of innovation process; this is the first paper that studies the NPD process based on the cross-functional relationship between marketing and sales. These drivers can help managers implement effective team processes to enhance innovation deployment results. This empirical research also expands theoretical boundaries of marketing/sales interface literature, providing evidence of organizational mechanisms in South America: an emerging geography that has been able to manage innovation process in a post-crisis, turbulent and highly competitive environment.
Determination of Individual Chlorobiphenyls (CBs), Including Non-Ortho, and Mono-Ortho Chloro Substituted CBs in Marine Mammals from Scottish Waters

Abstract Twenty individual chlorobiphenyls (CBs) have been determined in marine mammals. The more toxic non-ortho and mono-ortho CBs have been separated from di and tri-ortho CBs using a pyrenyl silica HPLC column prior to the final determination by capillary GC. The comparative metabolism of the biologically active CBs in whale, porpoise, dolphin and seal tissue is described. An estimate of the TCDD toxic equivalence concentration (TEC) for the non ortho and mono ortho CBs is made.

The study and comparative analysis of GerdQ and GSRS Questionnaires on gastroesophageal reflux disease diagnostics

Introduction Clinical questionnaires have some limitations compared to instrumental diagnosis of gastroesophageal reflux disease (GERD), but clinical diagnosis of GERD based on typical symptoms is pragmatic and well-established by societal guidelines. Aim To study the diagnostic value and provide comparative analysis of GerdQ and GSRS questionnaires regarding the GERD diagnostics based on a comparison of the questionnaires with the results of intraluminal oesophageal impedance-pH monitoring in Ukraine. Material and methods Twenty-eight patients (11 men and 17 women with a mean age of 47 ±2.4 years and a mean body mass index of 25.6 ±1.1 kg) filled in the GerdQ and GSRS questionnaires and underwent 24-hour multichannel intraluminal oesophageal impedance-pH monitoring. Results The GerdQ questionnaire showed a significantly strong correlation between the total score of the questionnaire and the key indicators of 24-hour impedance-pH monitoring: AET (rs = 0.793), acid reflux episodes (rs = 0.796), and liquid reflux episodes (rs = 0.730). Correlation of reflux syndrome according to the GSRS questionnaire was established between the acid reflux episodes (rs = 0.530), the episodes of all fluid refluxes (rs = 0.598), and AET (rs = 0.560), but the strength of the correlation relationships is weaker. The GerdQ questionnaire showed a sensitivity of 78.6%, specificity of 92.9%, and accuracy (diagnostic efficiency) of 85.7%. Conclusions The use of the GerdQ questionnaire for the diagnosis of GERD is optimal in everyday practice for deciding whether to prescribe “ex juvantibus” therapy or whether to use instrumental examination methods (upper endoscopy, oesophageal pH monitoring, oesophageal impedance-pH monitoring).
Multi-Agent Active Search and Rescue

In this paper, we propose a parallel active learning algorithm called SPATS (sparse parallel asynchronous Thompson sampling) that using multiple ground robots (agents) efﬁciently locates survivors of disasters. Unlike existing algorithms, SPATS is a practical algorithm that takes into account sparsity, lack of reliable communication to a central unit and sensing action constraints
Environmental and Exergetic Aspects of Geothermal Energy

Geothermal energy is already in the form of heat, and from the thermodynamic point of view, work is more useful than heat because not all heat can be converted to work. Therefore, geothermal resources should be classified according to their exergy, which is a measure of their ability to do work. In recent years there has been a remarkable growth of interest in environmental issues—sustainability and improved management of development in harmony with the environment. Environmental impact assessment is one of the most widely used tools in environmental management. In this study, the environmental and exergetic aspects of geothermal energy, namely the rapid impact assessment matrix method, and, specific exergy index, were studied first. They were then applied to the Tuzla geothermal field in Canakkale and Balcova geothermal field in Izmir, Turkey, respectively. Finally, the results obtained are given and discussed.
In situ study: Effect of a 10% Carbamide Peroxide whitening gel on enamel mineral density using NanoCT

Objective: Investigating effects of ten percentage from carbamide peroxide bleaching agent on possible demineralisation of enamel surface to include assessment of the mineral density of human enamel which measure through using X-ray NanoCT scanning technique. Methods: Sixty enamel slabs obtain from human molars. Four slabs from a single tooth were used for each intra-oral device (two slabs acting as controls and two slabs being subjected to bleaching). A total of 15 volunteers included in our investigation. The volunteers were advised to wear the intra-oral devices containing the slabs for a period 16 hours a day and the study duration of 14 days. Volunteers advise to wear intra-oral devices containing the slabs 16 hr a day for 14 days. Bleaching was carried out ex-vivo for 8 hr / day throughout used ten percentage from carbamide peroxide bleaching agent. Control slabs on appliance were treated with the control gel. The baseline mineral density of the enamel slabs was measured prior to the experiment using NanoCT scan and at end of the experiment post-bleaching procedure. This allowed changes in mineral density to be assessed in the bleached and unbleached slabs. Results: Daily bleaching production have no significantly effects on inner enamel while increasing mean mineral density at enamel surface by (6.8%), which might be refer to the peroxide incorporates in hydroxyapatite lattice and modifies mineral ratio. Significance: To simulated at-home, bleaching as possible, an in situ model selected. Bleaching with ten percentage of carbamide peroxide did not have detrimental effects on mineral density and increased mineral density.
Parkinson’s Disease Detection Based on a Heterogeneous Acoustic Database

A database composed of 50 individuals suffering from PD and 50 healthy controls has been collected to develop and validate an automatic diagnosis system. 46 acoustic features were initially extracted, which were reduced after feature selection. Repeated measurements taken on the same individual have been averaged before being assigned to subject, avoiding the usual practice of considering measurements within the same subject as independent. A classification experiment has been conducted based on support vector machines. Performance has been estimated by using k-fold cross-validation for different kernel functions. According to the obtained results, PD can be detected with an accuracy of 85% (sensitivity 83,74% and specificity 87,48%) based on recordings of the sustained vowel /a/. These results are remarkable, since the PD patients were under treatment and the effects of the disease were decreased.

Kinetic study of methacrylate copolymerization systems by thermoanalysis methods

The free-radical solution copolymerization of isobutyl methacrylate with lauryl methacrylate in the presence of an inhibitor was studied with thermoanalysis methods. A set of inhibited polymerization experiments was designed. Four different levels of initial inhibitor/initiator molar ratios were considered. In situ polymerization experiments were carried out with differential scanning calorimetry. Furthermore, to determine the impact of the polymerization media on the rate of initiation, the kinetics of the initiator decomposition were followed with nonisothermal thermoanalysis methods, and the results were compared with in situ polymerization counterparts. The robust M-estimation method was used to retrieve the kinetic parameters of the copolymerization system. This estimation method led to a reasonable prediction error for the dataset with strong multicollinearity. The model-free isoconversional method was employed to find the variation of the Arrhenius activation energy with the conversion. It was found that robust M-estimation outperformed existing methods of estimation in terms of statistical precision and computational speed, while maintaining good robustness. © 2008 Wiley Periodicals, Inc.

Investigate the Influence of Social Network Sites on Consumers behaviour: Applying the Technology Acceptance Model

This study is aiming to investigate the factors that affect consumers‘ online purchase intention through social network sites (SNSs). Theory of reasoned action (TRA) and the technology acceptance model (TAM) were utilized to develop the conceptual framework. Two constructs namely perceived usefulness and behavior intention in addition to the relevant literature on social media and trust was tested. particularly, this study examines i) effects of social media(SM) on trust; ii) effects of trust on perceived usefulness; iii) effects of perceived usefulness and trust on purchase intentions. Data were gathered from 42 graduates and undergraduate students using the stratified sampling method were analyzed using structural equation modeling and partial least square method.The data obtained from the questionnaire show that social media facilitates social interaction between consumers, which increases the trust level and intention to purchase. The results also revealed that trust was the most dominant construct had a statistically significant effect (α=0.05) on behavioral intention to purchase on the Internet, followed by perceived usefulness of a website. For this study, results, along with practical implications and recommended future research directions were discussed.
Cigarette smoke exposure inhibit antibody production via inhibition of alveolar macrophage

Cigarette smoke (CS) consists of mainstream smoke, sidestream smoke, growing smoke, diffusion smoke, effusion smoke, smoldering smoke and blowing smoke, which are exhaled by a smoker [1,2]. CS, except for mainstream smoke, is called environmental tobacco smoke (ETS) [2]. Approximately 6,000 different chemicals are found in CS, and 200 of these are considered as toxic substances [3]. CS has a gas phase and a particle phase. Carbon monoxide and ammonia are part of the gas phase. The particle phase includes nicotine and benzopyrene. CS includes many kinds of carcinogen and cancer promoters [2,4]. Cigarette smoking, a major risk factor for development of cancer, has also been associated with an increased incidence of infections, chronic pulmonary obstructive disease (COPD), asthma and bronchitis [5,6].
