The Role of Entrepreneurship Education in Fostering Entrepreneurial Intentions and Performances: A Review of 30 Years of Research

Many scholars have stressed on the strong relationships between entrepreneurship, self-employment and the labor market growth in contemporary society. Several training and academic programs have been designed and developed all around the world to increase entrepreneurial propensity. This article aims to show the empirical evidences about the effects of entrepreneurship education programs on perceived attractiveness and perceived feasibility of new venture initiation, entrepreneurship-related human capital assets and entrepreneurship outcomes. Moderators affecting the relationship between entrepreneurship education and entrepreneurial intentions and outcomes—such as the attributes of education itself, the individual’s background, and the contextual factors—have been analyzed. Explorations of the main theoretical frameworks that argue the positive relationships between entrepreneurship education and entrepreneurial intentions and performance have been conducted. Different pedagogical models adopted for entrepreneurship education programs have been compared. The study was conducted through the systematic literature review method, allowing the suggestion of evidence-based policies at an organizational and a national level of analysis. The role of entrepreneurship education in adjusting and refining the participants’ assessment of their own entrepreneurial aptitude can explain the small positive relationship between entrepreneurship education and entrepreneurial intentions revealed by several meta-analyses.
On optimal thermal control of an idealized room including a max-control cost term

We study an open-loop optimal control problem for energy efficient cooling of a simple room. The goal is to provide insights for the development of an implementable control scheme based on a Model Predictive Control strategy. The cost function includes a non-standard Mayer-term $ F(\max_t u(t)) , $ that is, a term depending on the peak value of the control. Necessary conditions for an optimal control problem are formulated and it is observed that candidates of optimality can be obtained as solutions of a related two-point boundary value problem (TPBVP). Due to numerical issues a finite dimensional approximation of the optimal control problem is considered to provide approximations to the solutions of the TPBVP. The procedure is then illustrated on a numerical example.
Cytotoxic flavonoids from Diplotaxis harra (Forssk.) Boiss. growing in Sinai

As part of our ongoing collaborative effort to discover the anticancer activity of the phenolics isolated from terrestrial plant sources, the EtOH extract of the aerial parts of the Egyptian medicinal plant Diplotaxis harra (Forssk.) Boiss. was in vitro investigated for cytotoxicity against HCT116, HepG2 and MCF-7 cell lines, and resulted with IC50 = 4.65, 12.60 and 17.90 µg/ml, respectively. Doxorubicin (+ve control) showed in vitro cytotoxic activity with IC50 = 3.64, 4.57 and 2.97 µg/ml, respectively. The phenolic-rich fraction of the EtOH extract was subjected to further fractionation, which led to the isolation of five flavonoids; identified as quercetin, quercetin 3-O-β-glucoside, isorhamnetin 7-O-β-glucoside, apigenin 3-O-β-rhamnoside and kaempferol 3-O-β-glucoside, according to its’ spectral data and comparison with the literature. Furthermore, the isolated flavonoids showed in vitro cytotoxicity against HCT116 cell line with IC50 = 20.1, 24.3, 22.8, 23.4 and 41.9 µg/ml as determined by NADHDIAPHORASE (MTT method). Key words: Diplotaxis harra (Forssk.) Boiss. , cruciferae, flavonoid glycosides, cytotoxicity.

A literature review of a set of implementation studies of educational policies that incorporate educational accountability was conducted to discover what elements of this mechanism help or hinder educational improvement in the specific contexts in which they are applied. A discussion of the results of this review and projections for Latin America are presented at the end of the paper.
Estimates of Critical Thermal Environments for Mule Deer

Mule deer (Odocoikus hemlonus hemionus) can be thermally stressed under a wide range of ambient conditions. We developed a model that provides examples of the combinations of wind, solar radiation, and air temperature that may result in thermally critical environments for standing, full-fed adult mule deer during winter in snow-covered and snow-free, open habitats, and in meadows in summer. Critical thermal combinations of environmental variables are shown as 3-dimensional surfaces and tables. Animal size, age, pelage characteristics, and gound cover (height and albedo) further affect the energy costs for thermoregulation by mule deer. The need for habitat managers to consider the provision of thermal cover to reduce beat or cold stress in mule deer depends on the combinations of environmental variables in a particular habitat and geographic location. Implications, limitations, and management consideratiom of our estimates are discussed.

DESIGN OF MICRO STRIP ANTENNA AND STUDY OF PARAMETES BY VARYING THE FREQUENCY Poonam Devi Student of M.Tech. (ECE) 3 Semester, Department of Electronics & Communication Engineering, Sri Sai University, Palampur (H.P.), INDIA __________________________________________________________________________________________ Abstract: Today the micro strip antennas are mostly used in wireless communication due to its advantages such as small size, low cost, light weight etc. But there are some drawbacks with these antennas like low gain, narrow bandwidth, and low efficiency. In this paper we increase the bandwidth by varying the frequency. The rectangular micro strip antenna is operated at frequency (1.5, 4.5 and 9.5 GHz ) and dielectric substrate(2.2) for the height 0.05cm . We calculate the width, length, VSWR and bandwidth when antenna is fed by a transmission line of 50 ohm. Input impedance is calculated by error and trial method.
Optimization of the Water Absorption by Crosslinked Agar-g-Poly(acrylic acid)

Crosslinked agar-g-poly(acrylic acid)(x-agar-g-PAA) superabsorbent with a water absorbency (QH2O) of approximately 660 g/g was synthesized by the copolymerization of agar with an acrylic acid monomer. KPS and MBA were used as the initiator and crosslinker, respectively. Grafting was performed in air. Infrared spectroscopy was used to identify the product of copolymerization. The optimum conditions to synthesize the x-agar-g-PAA superabsorbent were 0.1 g of agar, 0.1 g of the KPS initiator, for 15 min; 50% AA monomer, 0.005 g of the MBA crosslinker, for a propagation time of 5 min; and 1 M NaOH for 15 min to allow for saponification. The reaction temperature was 80 ℃.
Review: The Self-Assembly Approach for Organ Reconstruction by Tissue Engineering

One must not forget that tissue engineering was first introduced as a life saving procedure for burn patients (1). The successful engraftment of autologous epidermal sheets was the first proof of concept of the powerful technology that we know today (2–4). However this very interesting initial approach fell into some disrepute because of perceived drawbacks and limitations (5, 6). The subsequent efforts in the field followed essentially three “schools” of thought. The first approach consists of the seeding of cells into various gels, which are then reorganized, by the incorporated cells (7–14). Alternatively, a second approach is to seed cells into a scaffold where they will thrive and secrete extracellular matrix (15–17). The scaffold materials are bioresorbable over a wide range of time periods depending on their chemical structures (18–25). A third approach is different since it uses the principle of a tissue template that allows, after implantation, the ingress of cells into the appropriately organized scaffold. Thus, these grafts are acellular and must stimulate the regenerative potential of the tissue wherever they are implanted (26–31). Our group has developed a different and original method for the reconstruction of soft tissues. It takes full advantage of the various intrinsic properties of cells when appropriately cultured. This entails particular media composition and appropriate mechanical straining of these three-dimensional structures.
FIELD-INDUCED VALENCE TRANSITION OF EU(PD1-XPTX)2SI2

The magnetic susceptibility and high-field magnetization have been measured for the intermediate valence system Eu(Pd 12xPtx)2Si2 with 0<x<0.15. A first-order valence transition is observed for all the compounds under high field of 100 T at low temperatures. This valence transition is of first order accompanied with a large hysteresis, which is in contrast to a continuous valence change against temperature. Based on the interconfigurational fluctuation~ICF! model, the temperatureand field-induced valence transitions are discussed. It is found that a first-order valence transition can be induced by magnetic field, even if the system shows a continuous valence transition against temperature. Metamagnetic behavior at finite temperatures is also understood qualitatively by the ICF model. @S0163-1829 ~97! 06817-3#
How Creating Shared Value Differs From Corporate Social Responsibility

Abstract Purpose: This study attempts to make a contribution to theory by disentangling the concept of creating shared value (CSV) from corporate social responsibility (CSR). In doing so, the study provides a preliminary outline for CSV analysis. Approach: This study is conceptual in character. It is based on a review of literature on CSR and CSV and adopts the perspective of economic and social value creation. Findings: The findings show that 1) CSR comes down to sharing the economic value created in order to build social value and 2) CSV is the process of change of the relation between a firm’s outcomes and inputs that generates social value. In other words, it comes down to economic value creation through creating social value. Originality: This study provides arguments revealing that understanding the differences between the notions of CSV and CSR, reqnires adopting the concepts of economic and social value. The study therefore bridges the gap in theory in this respect and outlines a preliminary conceptual basis for CSV analysis. It is expected that the findings of this study will serve as a reliable basis for further discussion and CSV concept development.
Surface Kinetic Energy Transfer in SQG Flows

The relevance of surface quasi-geostrophic dynamics (SQG) to the upper ocean and the atmospheric tropopause has been recently demonstrated in a wide range of conditions. Within this context, the properties of SQG in terms of kinetic energy (KE) transfers are revisited and further explored. Two well-known properties of SQG in spectral space are (i) the identity between surface velocity and density spectra (when appropriately scaled) and (ii) the existence of a forward cascade for surface density variance. Here we show numerically and analytically that (i) and (ii) do not imply a forward cascade of surface KE (through advection). On the contrary, advection by the geostrophic flow primarily induces an inverse cascade of surface KE on a large range of scales. This spectral flux is locally compensated for by a KE source, linked to surface frontogenesis, that is interpreted as a conversion of potential to kinetic energy. The subsequent spectral budget resembles those exhibited by more complex systems (primitive equation or Boussinesq models) and observations, which strengthens the relevance of SQG for the description of ocean/atmosphere dynamics near vertical boundaries. The main weakness of SQG however is in the small-scale range (scales smaller than 20-30km in the ocean) where it poorly represents the forward KE cascade observed in non-QG numerical simulations.
Romanian aromatic plants as sources of antioxidants.

Nowadays the concept of chemical preservatives in foods is very controversial. Consumers’ choices redirect towards healthier and more natural alternatives. Spices and herbs have been used not only for flavoring food but also for improving the overall quality of the product and to extend the shelf-life of foods. The possibility of using some Romanian aromatic plants, oregano (Origanum vulgare), tarragon (Artemisia dracunculus), wild thyme (Thymus serpyllum), as a new source of natural antioxidant has been investigated using extraction with ethanol. Many in vitro methods have been developed to evaluate antioxidant activity. The most widely used ones being the DPPH, ABTS, FRAP, ORAC assays. These assays are time-consuming, and when pro-oxidant compounds are to be evaluated, it suffers serious invalidity, especially in the presence of catalycally active iron. Total polyphenol content of the plant extracts was measured based on the Folin-Ciocalteu method. The antioxidant activity of the extracts was determined using PHOTOCHEM ® , from Analytik Jena (Germany). The analytical method used in this study, the PCL assay, was chosen because it is rapid, sensitive, relatively simple and reproducible. The result may suggest that the plant extracts possess compounds with antioxidant activity, and therefore can be used as natural preservative ingredients in food industry.
The La Nina episode and the heavy winter rainfall of 1999 over Peninsular Malaysia

Prolonged events of heavy rainfall which commenced in September 1999 and continued until January 2000 during the northeast monsoon over the Malaysian Peninsula showed that the enhanced rainfall conditions were related to the larger scale La Nina phenomenon. This was substantiated by large-scale observational features, such as the monthly precipitation, anomaly of outward long wave radiation, zonal and meridional wind fields at the lower and upper levels, vorticity and vertical motion, that exhibited a disparity from the El Nino conditions of 1997. Low-level convergence concentrating over the maritime continent coincided with the region of enhanced rainfall. The more frequent occurrences of heavy rainfall and flooding during this period fell within the La Nina episode, occurring approximately two years after the major dry episode of the El Nino phenomenon. The enhanced rainfall encountered by Peninsular Malaysia was considered to be related to the transitional phase of the Tropical Biennial Oscillation. The causes of these heavy rainfall episodes were variable and included the localized and organized enhanced afternoon convection resulting from the radiative diurnal cooling and heating effects. The heavy rainfall in early October 1999 was associated with the presence of the confluence of airstreams along the Malaysian Peninsula at cyclonic vortices of 850, 250 and 100 hPa over the northern Malaysian Peninsula. Two westward propagating tropical cyclones which existed over the Bay of Bengal and the Gulf of Siam were among the main contributors to the heavy rainfall over the region during October.

The Impact of Financial and Social Capital on Performance

In the present study it is shown that in a situation with an external crisis signal, such as a drop in stock prices, finns with a decision-competent executive team (a socially integrated team) take longer to recover than do firms with information-competent executive teams (s o cially differentiated teams). The hypothesis is that the decision-competent team has a social network that effectively resists changes such as takeovers and changes in controlling shareholders. Hence, resisting changes buys the team time to look over the activities in the firms. However, management in the entrepreneurial-owned firm has no such option to buy time. Takeovers and changes in the controlling shareholders are efficient ways of restructuring businesses that also affect the performance, measured as performance on the stock exchange. The statistical analysis is bas ed on data from 29 Swedish public companies and their executive team members.

FORENSIC LINGUISTICS: AUTOMATIC WEB AUTHOR IDENTIFICATION

Internet is anonymous, this allows posting under a false name, on behalf of others or simply anonymous. Thus, individuals, criminal or terrorist organizations can use Internet for criminal purposes; they hide their identity to avoid the prosecuting. Existing approaches and algorithms for author identification of web-posts on Russian language are not effective. The development of proven methods, technics and tools for author identification is extremely important and challenging task. In this work the algorithm and software for authorship identification of web-posts was developed. During the study the effectiveness of several classification and feature selection algorithms were tested. The algorithm includes some important steps: 1) Feature extraction; 2) Features discretization; 3) Feature selection with the most effective Relief-f algorithm (to find the best feature set with the most discriminating power for each set of candidate authors and maximize accuracy of author identification); 4) Author identification on model based on Random Forest algorithm. Random Forest and Relief-f algorithms are used to identify the author of a short text on Russian language for the first time. The important step of author attribution is data preprocessing discretization of continuous features; earlier it was not applied to improve the efficiency of author identification. The software outputs top q authors with maximum probabilities of authorship. This approach is helpful for manual analysis in forensic linguistics, when developed tool is used to narrow the set of candidate authors. For experiments on 10 candidate authors, real author appeared in to top 3 in 90.02% cases, on first place real author appeared in 70.5% of cases.
Locational wireless and social media-based surveillance

The number of smartphones and tablets as well as the volume of traffic generated by these devices has been growing constantly over the past decade and this growth is predicted to continue at an increasing rate over the next five years. Numerous native features built into contemporary smart devices enable highly accurate digital fingerprinting techniques. Furthermore, software developers have been taking advantage of locational capabilities of these devices by building applications and social media services that enable convenient sharing of information tied to geographical locations. Mass online sharing resulted in a large volume of locational and personal data being publicly available for extraction. A number of researchers have used this opportunity to design and build tools for a variety of uses – both respectable and nefarious. Furthermore, due to the peculiarities of the IEEE 802.11 specification, wireless-enabled smart devices disclose a number of attributes, which can be observed via passive monitoring. These attributes coupled with the information that can be extracted using social media APIs present an opportunity for research into locational surveillance, device fingerprinting and device user identification techniques. This paper presents an in-progress research study and details the findings to date.
Leucine levels in low protein diets for pigs in the initial phase

The objective of this study was to evaluate the standardized ileal digestible (SID) leucine levels in low crude protein diets on Performance, backfat thickness, longissimus dorsi depth and biochemical blood parameters of starting pigs. A total of 50 pigs, with initial weight of 11.14±0.24 kg; were distributed in a randomized blocks design with five treatments (1.10; 1.25; 1.40; 1.55 and 1.70% SID leucine), five replicates and two animals per experimental unit, comprised for a barrow and a gilt. The feed conversion ratio (FCR) reduced (P=0.018) due to the increasing SID leucine levels, without affecting other growth performance parameters (final weight, average daily feed intake, average daily gain, backfat thickness, longissimus dorsi depth and lean meat percentage). There was a quadratic effect for plasma triglyceride (P=0.049) and plasma urea (P=0.001). The optimal SID leucine levels obtained for triglycerides and urea were 1.16% and 1.24%, respectively, by associating the quadratic model with the Linear Response Plateu. Low crude protein diets with SID leucine levels up to 1.70% improved the feed conversion with desired urea and triglycerides concentration in blood plasmas achieved at 1.16% and 1.24%, respectively.

Reflection and Transmission of Longitudinal Wave at Micropolar Viscoelastic Solid/Fluid Saturated Incompressible Porous Solid Interface

In this paper, the reflection and refraction of longitudinal wave from a plane surface separating a micropolar viscoelastic solid half space and a fluid saturated incompressible half space is studied. A longitudinal wave (P-wave) impinges obliquely at the interface. Amplitude ratios for various reflected and transmitted waves have been obtained. Then these amplitude ratios have been computed numerically for a specific model and results thus obtained are shown graphically with angle of incidence of incident wave. It is found that these amplitude ratios depend on angle of incidence of the incident wave as well as on the properties of media. A particular case when longitudinal wave reflects at free surface of micropolar viscoelastic solid has been deduced and discussed. From the present investigation, a special case when fluid saturated porous half space reduces to empty porous solid has also been deduced and discussed with the help of graphs. © 2014 IAU, Arak Branch.All rights reserved.
