Relation between Entrepreneurial Curiosity and Entrepreneurial Self-efficacy: a Multi-Country Empirical Validation

Abstract The main purpose of this paper is to present empirical analysis of the relation between entrepreneurial curiosity and entrepreneurial self-efficacy. A detailed literature review in a broad field of entrepreneurship, narrow field of entrepreneurship psychology, and organizational sciences revealed, at one hand different connections between determinants influencing entrepreneurs, and latest scientific research trends on the other hand. Although the significance of curiosity in motivating and learning has received expressive scholarly support, like also entrepreneurial self-efficacy as one of the most studied personal attributes among entrepreneurs, no study to our knowledge existed in relation to entrepreneurial curiosity connected with entrepreneurial self-efficacy. An online multi-country survey was conducted in Slovenia and USA among entrepreneurs and results of structural equation modelling showed that entrepreneurial curiosity and entrepreneurial self-efficacy are related. Entrepreneurial curiosity has a positive impact on entrepreneurial self-efficacy of running entrepreneurial tasks. The findings of this research have both theoretical and practical implications.
Effect of increased temperature on carbon and nitrogen uptake oftwo intertidal foraminifera ( Ammonia tepida and Haynesinagermanica )

Benthic foraminifera are highly abundant heterotrophic protists in marine sediments, but intertidal communities are expected to undergo future changes. Environmental changes can exceed the tolerance limits of intertidal species causing a shift in species composition which might result in altered nutrient fluxes. Factors limiting the abundance of specific foraminiferal species can be temperature related stress tolerance or food source processing efficiency. In this study, we performed a laboratory feeding experiment on Ammonia tepida and Haynesina germanica, two dominant foraminiferal species of the German Wadden 5 Sea/Friedrichskoog, to test the effect of temperature on phytodetritus ingestion. The specimens were fed with 13C and 15N labelled freeze dried Dunaliella tertiolecta (green algae) at the start of the experiment and were incubated at 20◦C, 25◦C, and 30◦C respectively. Dual labelling was applied to observe potential temperature effects on the relation of phytodetrital carbon and nitrogen retention. Samples were taken over a period of two weeks. Foraminiferal cytoplasm was isotopically analysed to investigate differences in carbon and nitrogen uptake derived from the food source. Both species showed a positive response 10 to the provided food source, but carbon uptake rates of A. tepida were 10-fold higher compared to those of H. germanica. Increased temperatures had a far stronger impact on carbon uptake of H. germanica than on A. tepida. A distinct increase in levels of phytodetrital derived nitrogen (compared to more steady carbon levels) could be observed over the course of the experiment. The results suggest that higher temperatures have a significant negative effect on the carbon exploitation of H. germanica. For A. tepida, higher carbon uptake rates and the enhanced tolerance range for higher temperatures could outline 15 an advantage in warmer periods, if the main food source consists of chlorophyte phytodetritus. These conditions are likely to impact nutrient fluxes in A. tepida/H. germanica associations.
Output-Feedback Control for a Class of Stochastic High-Order Feedforward Nonlinear Systems with Delay

The problem of global output-feedback stabilization for a class of stochastic high-order time-delay feedforward nonlinear systems with different power orders is investigated. By combining the adding one power integrator technique with the homogeneous domination approach, an output-feedback controller design is proposed, which ensures the global asymptotical stability in probability of the closed-loop system.

EFFECTIVENESS OF THE MANAGEMENT OF PRICE RISK METHODOLOGIES FOR THE CORN MARKET BASED ON TRADING SIGNALS

Corn production is scattered geographically over various continents, but most of it is grown in the United States. As such, the world price of corn futures contracts is largely dominated by North American corn prices as traded on the Chicago Board of Trade. In recent years, this market has been characterised by an increase in price volatility and magnitude of price movement as a result of decreasing stock levels. The development and implementation of an effective and successful derivative price risk management strategy based on the Chicago Board of Trade corn futures contract will therefore be of inestimable value to market stakeholders worldwide. The research focused on the efficient market hypothesis and the possibility of contesting this phenomenon through an application of a derivative price risk management methodology. The methodology is based on a combination of an analysis of market trends and technical oscillators with the objective of generating returns superior to that of a market benchmark. The study found that market participants are currently unable to exploit price movement in a manner which results in returns that contest the notion of efficient markets. The methodology proposed, however, does allow the user to consistently achieve returns superior to that of a predetermined market benchmark. The benchmark price for the purposes of this study was the average price offered by the market over the contract lifetime, and as such, the efficient market hypothesis was successfully contested.
A Numerical and Analytical Study of Intermittency in the Stable Boundary Layer

This paper studies the phenomenon of intermittency in the stable boundary layer with particular emphasis on the energetic coupling between land and atmosphere. The stable boundary layer is modelled with two different minimalistic models, a one-dimensional (height-dependent) model and a bulk model. Turbulence is parameterized using a Richardson number dependent eddy viscosity. The most important ingredient of both models is the treatment of the lower boundary: it is based on a simplified energy balance of a vegetation layer and includes besides radiative cooling an energetic coupling with both the atmosphere and the deep soil. The resulting temperature boundary condition is time-dependent and interacts with the atmospheric dynamics. For a large range of parameters both models display unsteady behaviour where the state of the atmosphere changes between turbulent and laminar (collapsed turbulence). But sustained unsteady behaviour appears only possible when the coupling between vegetation and atmosphere is sufficiently strong. Both models show qualitative comparable behaviour. This provides a strong indication that the surface-atmosphere interaction could play an important role in the occurrence of intermittency in the stable boundary layer.

Theoretical Application of the Tensorial Analysis of Network for EMC at the System Level

To resolve the Electromagnetic compatibility (EMC) at the system level we need to compute physical phenomenon and to connect various patterns existing at various scales. With this intention we need a technique able to link schematics coming from various jobs: electronic, harnesses and structures. This paper presents a technique based on the topological tensorial analysis of network developed by Gabriel KRON to compute all the interactions encountered in EMC on large systems.
Feature Analysis of Eyeblink Waveform for Automatically Classifying Conscious Blinks

In this paper, we propose and evaluate a new feature parameter of eyeblink for automatically classifying between conscious (voluntary) and unconscious (spontaneous) blinks. We focused on integral values of an eyeblink waveform, which is defined as a measurement record of a progression of eyeblinks, as the feature parameter. Previous researchers have used duration time and waveform amplitude as the feature parameter, whereas the integral values have both feature parameter characteristics. We obtained these parameters using an NTSC video camera by splitting a single interlaced image into two fields. We used flame-splitting methods to obtain and analyze the integral value of the eyeblink waveform, and we experimentally compared the feature parameters to automatically classify the conscious and unconscious eyeblink. Duration and amplitude did not show a significant difference in some subject cases, but we confirmed a significant difference when using the integral value. Our results suggest that integral values of eyeblink waveform are effective for classifying the two eyeblink types.
Mediating effects of educational level on job related characteristics: Job satisfaction relationship

This paper will analyze the mediating influence of educational level on job related characteristics-job satisfaction relationship. The main research questions are whether the level of education influences job satisfaction. In order to answer this question, MANOVA was applied using the data obtained by the primary research on a sample of 813 employees in the companies in Serbia. Results of the study showed that job satisfaction is rising with increasing the level of education, except in case of highest level of education. Also, all job related characteristics (except contingent rewards) have significantly different influence on job satisfaction of employees with different levels of education. The results also showed that pay has greater influence on job satisfaction of the lowest educated employees than it has on job satisfaction of others. For employees with secondary education, communication and relationship with co-workers has such influence. For job satisfaction of employees with higher level of education, relationships with superiors and operating procedures have greater influence, while for the highest educated employees those are fringe benefits and nature of work.
Ontogenetic variation in light interception, self-shading and biomass distribution of seedlings of the conifer Araucaria araucana (Molina) K. Koch

La caida en la eficiencia de intercepcion de la luz es considerada como uno de los factores responsables del declive ontogenetico en las tasas de crecimiento relativo de las plantas, debido a la dificultad de evitar el autosombramiento entre un creciente numero de hojas. Sin embargo, rara vez se ha cuantificado el efecto de tamano de las plantas sobre el autosombramiento y la eficiencia en intercepcion de la luz. Utilizamos un sistema de digitalizacion para construir modelos virtuales tridimensionales de la arquitectura de plantulas 71-358 mm de alto de la conifera Araucaria araucana, y modelamos su intercepcion de la luz en el sotobosque mediante el programa YPLANT. Analizamos ademas la alometria de las plantulas para determinar los efectos combinados de la distribucion de biomasa y el autosombramiento sobre la intercepcion total de luz a nivel de la planta entera. La eficiencia promedio de intercepcion de la luz de A. araucana (29 %) fue la mas baja documentada para plantulas de especies de bosques humedos, reflejando las limitaciones impuestas por hojas cortas, carencia de peciolos, y la incapacidad de desarrollar follaje plagiotropico. La intercepcion total de luz por las plantulas fue proporcional al area foliar0,735, producto de un aumento en el autosombramiento en funcion del tamano. Sin embargo, debido a la relacion del area foliar con la potencia 1,24 de la masa de las plantulas, la intercepcion de luz se acerco a la proporcionalidad directa (exponente 0,91) con la masa. Este patron fue producto de la relativa delgadez de los tallos de las plantulas grandes, y su baja proporcion de biomasa radicular. Por tanto, el declive ontogenetico en la eficiencia de intercepcion de la luz fue en gran medida compensada por cambios de asignacion que aumentaron la superficie foliar de las plantulas grandes. Estos mecanismos que conservaron la relacion de la ganancia potencial de carbono con la masa de las plantulas probablemente seran vistos solamente en especies con hojas muy longevas, en habitats humedos con poco viento. En ambientes abiertos, donde los estres por sequia y viento podrian seleccionar en contra tales patrones de asignacion, es probable que se evidencie mas claramente el rol del autosombramiento en los declives ontogeneticos en la tasa de crecimiento relativo
SOM Canonica: Establishing a standard algorithm for self-organizing maps

The purpose of this work is to establish a textbook algorithm for Self-Organizing Maps (SOM), called SOM Canonica. The algorithm of SOM Canonica is derived from a probabilistic generative model with Bayesian inference, while it still preserves the essential properties of Kohonen’s original SOM, especially the parametric representation of the posterior of the latent variables, namely the neighborhood function. Thus, in SOM Canonica, the posteriors of both the map and latent variable are parametrically represented. The motivation of this work is to re-establish the SOM as a useful tool of latent variable estimation; therefore, SOM Canonica be a powerful tool for realizing brain-like intelligence. We introduced the variational Bayesian method to derive the algorithm of SOM Canonica. Keywords— Self-Organizing Map, Topographic Mapping, Variational Bayesian, Generative Topographic Mapping
An overview of different methods of myocardial protection currently employed peri-transplantation

Myocardial protection is integral to the functioning of hearts in day to day cardiac surgery. However, due to the longer ischaemic times, it becomes pivotal in the management of organs during transplantation. There are many different strategies employed to ensure diligent and judicious myocardial protection during donor management, transportation of the heart and the post-operative period. Given the limited supply of organs and the increasing waiting lists for heart transplants worldwide, it has become an area of renewed interest with many innovations and inventions using the principles of basic sciences to improve outcomes of transplanted hearts. The heart procurement process encompasses several of the different myocardial protection strategies in tandem to provide the greatest benefit to the recipients. This review looks at the different modalities employed, which include different types of cardioplegia, the role of biomarkers, the cutting-edge novel therapies, hormonal therapies and ischaemic conditioning strategies.
The Participation of Oxidative Stress in Breast Cancer Cells Progression and Treatment Resistance

This article presents a general discussion about the participation of oxidative stress in relevant points related to breast cancer progression in vitro. All of the evidences presented here are based on published papers that used breast cancer cells with different phenotype characteristics in their research. We observed that oxidative stress could modulate by several manners the tumor progression and these effects are directly related to its concentration and time of cell exposure to these substances. Furthermore, oxidative stress produced and released by breast cancer cells is able to interfere in the metabolism of the adjacent normal cells in a manner that improve the survival of the neoplastic cells. In relation to breast cancer treatment, the role of oxidative stress is complex. At the same time that it can be responsible to the induction of cell death, oxidative stress can also modulate pathway that leads to increased expression of anti-apoptotic and resistance-related proteins. Therefore, the participation of oxidative stress in breast cancer is complex and very broad and its better understanding could be important to the development of more effective therapeutic strategies for the different forms clinically found of the disease.
Isolation of two novel isoforms encoding zinc- and copper-transporting P1B-ATPase from Gouan (Aeluropus littoralis).

Two new isogenes encoding heavy metal ATPase have been partially cloned from Aeluropus littoralis genome. One of them was 849 bp in length and related to an isoform which encodes a copper-transporting P1B -ATPase ( AlHMA1 ), and the other one was 403 bp in length and related to an isoform encoding a zinc-transporting P1B -ATPase ( AlHMA2 ). When southern blot hybridization was performed under low-stringency, 6 to 7 hybridization bands appeared, indicating that in this plant heavy metal ATPase is encoded by a multigene family. RT-PCR assay displayed that the AlHMA2 highly expresses in leaf and root and its transcription level is the same in both organs. Phylogenetic tree showed that copper transporters from different plants were located in one group and zinc transporters were located in another group, although all heavy metal P 1B -ATPasees have the same function. It means the different isoforms in single plant that involve in transporting of different heavy metals, may come from different sources.
A look at cloud architecture interoperability through standards

Enabling cloud infrastructures to evolve into a transparent platform while preserving integrity raises interoperability issues. How components are connected needs to be addressed. Interoperability requires standard data models and communication encoding technologies compatible with the existing Internet infrastructure. To reduce vendor lock-in situations, cloud computing must implement universal strategies regarding standards, interoperability and portability. Open standards are of critical importance and need to be embedded into interoperability solutions. Interoperability is determined at the data level as well as the service level. Corresponding modelling standards and integration solutions shall be analysed.
Lipid and Fatty Acid Composition of Wild Almaco Jack Seriola rivoliana at Two Maturation Stages

Almaco jack (Seriola rivoliana) is an emergent marine finfish that presents high market value. In order to study the feasibility of the exploitation of this marine resource for human consumption the evaluation of the nutritional characteristics of this species has attracted the attention of the scientific community. The lipid characteristics and fatty acid composition were evaluated in muscle, liver and gonad tissues of wild Almaco jack from Atlantic Ocean at two different maturation stages. According to results, the lipid content was found higher at pre-spawning stage (21.78 36.17%) and highest proportion being exhibited in the liver. Palmitic acid was predominant among the saturated fatty acids (35.42 47.80%) and oleic acid was detected as the main monounsaturated acid (25.26 36.55%). Higher amounts of ω3 polyunsaturated fatty acids (PUFAs) were identified in gonads of resting females, of which more than 84% was accounted by docosahexaenoic acid (12.62%). Muscle and liver of resting females presented the highest ω3/ω6 ratios. The Hypocholesterolemic/Hypercholesterolemic index was higher in gonads of both maturation stages (0.97 and 1.05). The results showed that wild Almaco jack at resting stage were a better source of oleic acid and ω3 PUFAs and that liver and gonads present good nutritional by-products.
Histological study on inoculated cotyledons of Brassica napus resistant and susceptible to Leptosphaeria maculans.

Infection process of Leptosphaeria maculans was studied on cotyledons of cultivars of spring-type Brassica napus. There were no differences between the resistant and susceptible cultivars in relation to the processes of pycnidiospore attachment, germination and penetration. However, differences among the cultivars were observed post-penetration. Rapid necrosis of cells and subsequent spread of necrosis to the cells around the penetration site to form a lesion led to a hypersensitive response in the resistant cultivar Surpass 400, a cultivar containing a single dominant resistance gene.
The correlation between solar and geomagnetic activity – Part 3: An integral response model

An integral response model is proposed to describe the relationship between geomagnetic activity ( aa index) and solar activity (represented by sunspot number Rz): The aa at a given timet is the integral ofRz at past times (t ′ ≤ t) multiplied by an exponential decay factor of the time differences ( e )/τ ), whereτ is the decay time scale ( ∼ 40 months). The correlation coefficient of aa with the reconstructed series based on this model ( rf = 0.85) is much higher than that ofaa with Rz (r0 = 0.61). If this model is applied to each solar cycle, the correlation coefficient will be higher (rf = 0.95). This model can naturally explain some phenomena related toaa andRz, such as (i) the significant increase in theaa index (and its baseline) over the twentieth century; (ii) the longer lag times of aa to Rz at solar cycle maxima than at minima; and (iii) the variations in the correlations related to solar and Hale cycles. These results demonstrate that aa depends not only on the present Rz but also on past values. The profile of aa can be better predicted from Rz by this model than by point-point correspondence.
Metallic Structure and Bonding

This article briefly describes the current physical model of metallic structure and bonding. An alternative soft-sphere model of metal structure is introduced. Limitations of the current model are given and properties of metals which can be accounted for by the soft-sphere model are discussed. A simple soft-sphere formula, which calculated internuclear distances of Group 1 and Group 2 crystalline binary salts to a remarkable degree of accuracy, is applied to calculate metallic radii (equal to half the internuclear distances) of Group 1 and Group 2 metals precisely. A simple expression previously used to calculate lattice energies using the soft-sphere radii concept is used to calculate enthalpies of formation of Group 1 and Group 2 metal ions and results compare well with observed values. The work functions of Group 1 and Group 2 metals are shown to be inverse functions of the soft sphere ionic radii.
