Entrepreneurship Motivation: Tunisian Case  [PDF]
Jamel Choukir, Mouna Baccour Hentati
American Journal of Industrial and Business Management (AJIBM) , 2013, DOI: 10.4236/ajibm.2013.38085

The entrepreneurship option was launched in Tunisia nearly one decade ago. The firm creation process seemed to be initiated especially to absorb the increasing number of undergraduates and graduates. Therefore, the main aim of the present research is to highlight the entrepreneurship motivation as a social issue and to understand the link existing between motivator factors and economic and social success. Hence, a survey by questionnaire was conducted based on 100 respondents representing Tunisian entrepreneurs. The results revealed that there are links between motivator factors and entrepreneurship as well as some ties between entrepreneurship, motivator factors and the antecedents, especially concerning gender, age and family background. The results have shown some differences existing between male and female entrepreneurs. Male entrepreneursmotivator factors are in the same importance with push and pull ones. Female entrepreneurs’ motivator factors are rather emotional. These results are statistically significance. Thus, the finding would be useful for the stakeholders to understand the entrepreneurship dynamic.


Export Intention of Small and Medium Tunisian Enterprises
Mouna Baccour-Hentati
Communications of the IBIMA , 2010,
Abstract: Due to globalization, export is considered as an essential asset for the continuity and profitability of businesses. Nevertheless, export is a complex process. To initiate and to develop this strategy, a business must clear away the internal and external constraints and take advantage of the stimulating factors. The latters show up at each stage of the process. These stimuli are especially decisive during pre - export behavior or the intention stage. So the export intention is explained by some variables: the differential advantages, the organizational predisposition and the perception of the risk. Our conceptual model has been applied on a sample of small and medium Tunisian enterprises (SME). Inspiring by churchill’s methodology, our principal conclusion is that export is the strategy implying less capital and risk than the other modes of entry. However this decision may turn up like suicidal if the firm having the intention to export doesn't proceed by an assessment of its export.
A Digital Phase Locked Loop Speed Control of Three Phase Induction Motor Drive: Performances Analysis  [PDF]
Ben Hamed Mouna, Sbita Lassaad
Energy and Power Engineering (EPE) , 2011, DOI: 10.4236/epe.2011.31009
Abstract: This paper deals with performance analysis and implementation of a three phase inverter fed induction motor (IM) drive system. The closed loop control scheme of the drive utilizes the Digital Phase Locked Loop (DPLL). The DPLL is safely implemented all around the well known integrated circuit DPLL 4046. An ex-perimental verification is carried out on one kw scalar controlled IM system drives for a wide range of speeds and loads appliance. This presents a simple and high performance solution for industrial applications.
Analysis of Teacher Perception’s of Students’ Participation in Physical Education Session in Sfax  [PDF]
Mouna Khecharem Damak, Mourad Bahloul
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.610107
Abstract: The concept of social representations is a polymorphous concept and is not always stable due to its interdisciplinary nature. In this paper, we will try to identify, on the one hand, the semantic universe of social representations of teachers and then identify the socio-cognitive and pedagogical processes which are at their origin, and on the other hand, tackle the problematic of the effects of social representations of students’ participation in physical education sessions as seen by Tunisian teachers. Actually, this study is part of a central question: “What does talking about social representations mean?”. As part of a convenience sampling, 200 novice and experienced physical education teachers voluntarily participated in this study. All the teachers work in secondary schools in the region of Sfax. The results of the study show that externals influence the relation-ship with the teacher, the relationship with others and pupils’ motivation plays a key role in students’ participation or non-participation during physical education.
Image de Gary entre monde réel et fictif
Mouna Aljoboory
Synergies Algerie , 2012,
Abstract: Notre présente étude porte sur La vie devant soi, un roman signé par Emile Ajar que Romain Gary a pris comme pseudonyme et vise à montrer l’importance du lien unissant Gary avec son récit de fiction car c’est à l’intérieur de ce rapport que se construit l’image de soi de l’auteur, à savoir l’ethos par lequel il peut s’autoreprésenter, tout en créant un personnage fictif portant et véhiculant l’histoire de sa vie. Nous soulevons ici l’importance de la présence de la métalepse à l’intérieur du texte littéraire de fiction qui cherche à identifier la nature de l’appartenance de l’auteur par rapport à son uvre et à ses lecteurs et s’interroge sur le r le que joue l’écriture fictive dans la construction d’un discours littéraire.
Which are variables that characterize general meeting voting in France?
Mouna Messaoudi
Journal of Computations & Modelling , 2012,
Abstract: We present a detailed synthesis of previous studies on general meeting (U.S.A, U.K, Japan, Canada…). At the empirical level, our study should permit to identify general assemblies French characteristics (verification of the application of Mansion rapport on SBF 120). We will try to present the explanatory variables that influence voting in French general meeting. We will examine whether the current literature on shareholder voting in the U.S. can be used as a broad indication of shareholder voting support in France. An analysis of 102 French general meeting in the period 2004-2006 shows that institutional investors are not significantly related to the likelihood of votes against a proposal. We also include the stock ownership of the outside shareholder in our model. We find that this has a positive influence on the likelihood of votes against a proposal. The proposal to authorize the management board to issue new shares and to limit or exclude preemptive rights is more likely to be voted against than other proposals. We add the performance variables. We find that firms with valuable growth opportunities, as reflected in a higher market-to book ratio, have a lower probability of votes against a proposal at the general meeting.
On some nonlinear partial diffrential equations involving the 1-Laplacian
Mouna Kraiem
Mathematics , 2005,
Abstract: Let $\Omega $ be a smooth bounded domain in $\R^N, N>1$ and let $n\in \N^*$. We are concerned here with the existence of nonnegative solutions $u\_n$ in $BV(\Omega)$, to the problem $$(P\_n) \begin{cases} -{\rm div} \sigma +2n (\int\_ \Omega u -1) {\rm sign}^+ (u)=0 \quad \text{in} \Omega, \sigma \cdot \nabla u= |\nabla u| \quad \text{in} \Omega, u \text{\rm is not identically zero}, -\sigma \cdot \overrightarrow {n} u=u \quad \text{on} \partial\Omega, \end{cases}$$ where $\overrightarrow {n}$ denotes the unit outer normal to $\partial\Omega$, and ${\rm sign}^+(u)$ denotes some $L^{\infty}(\Omega)$ function defined as: $${\rm sign}^+ (u). u =u^+, 0 \leq {\rm sign}^+(u) \leq 1.$$ Moreover, we prove the tight convergence of $u\_n$ towards one of the first eingenfunctions for the first $1-$Laplacian Operator $-\Delta\_1$ on $\Omega$ when $n$ goes to $+\infty$.

Mouna Kraiem
Mathematics , 2007,
Abstract: In this paper, we consider the analogous of the obtacle problem in $H_0^1(\Omega)$, on the space $W^{1,p}_0(\Omega)$. We prove an existence and uniqueness of the result. In a second time, we define the optimal control problem associated. The results, here enclosed, generalize the one obtained by D.R. Adams, S. Lenhard
On some nonlinear partial differential equations involving the 1-Laplacian
Mouna Kraiem
Mathematics , 2007,
Abstract: In this paper we present an approximation result concerning the first eigenvalue of the 1-Laplacian operator. More precisely, for $\Omega$ a bounded regular open domain, we consider a minimisation of the functional ${\ds \int_\Omega}|\nabla u|+n({\ds \int_\Omega} |u|-1)^2 $ over the space $W_0^{1,1}(\Omega)$. For $n$ large enough, the infimum is achieved in some sense on $BV(\Omega)$, and letting $n$ go to infinity this provides an approximation of the first eigenfunction for the first eigenvalue, since the term $n({\ds \int_\Omega} |u|^2-1)^2$ "tends" to the constraint $\|u\|_1=1$.

Abstract: Recent years have seen the growth of new pattern recognition applications which based on personal biometric characteristics. These applications are used for security, logical or physical access control, etc. Iris recognition has been successfully deployed in several large-scale public applications. In this paper, three different methods are proposed to accelerate the simulation of biometric systems based on iris recognition with performance analysis. The whole iris recognition algorithm has been implemented inCyclone II FPGA achieving significant reduction in execution time when compared with software implementation .The results show that with a clock speed of 50MHZ from image of 640*480, the gain in bestmethod in the time execution is just 33% and the total time need by a software solution running on the same embedded microprocessor in the architecture.
