Authors: Otero Gómez María Cristina , Giraldo Pérez Wilson , Sainz Barajas María Teresa de la Luz , Aguirre Aleman María Guadalupe 
Published: February 2019

This article is the result of a scientific investigation and has been raised around the objective of analyzing and comparing the influence of personal and social characteristics on the predisposition to innovate in the young consumers of Villavicencio - Colombia and Coatzacoalcos - Mexico. For the development was carried out to survey 1591 university students of the two cities. The age range of the sample was between 17 and 25 years. To this end, the University of Los Llanos and the Universidad Veracruzana collaborated. The results show that there is no association between the predisposition to innovate and the variables of personal or social characteristics studied. This means that a strategy of demographic segmentation is not enough, since the determinants of the behavior of the segment may be influenced by their personal motivations, or by the characteristics of the products.El presente artículo es resultado de una investigación científica y se ha planteado en torno al objetivo de analizar y comparar la influencia de las características personales y sociales en la predisposición a innovar en los consumidores jóvenes de Villavicencio - Colombia y Coatzacoalcos - México.

Published: February 2019

The growing concern of the economies to achieve favorable growth rates has been a constant challenge, so it is intended to present the development of clústers as alternatives to achieve regional growth. Besides is appeled an analytical method that compares several theories and identifies the most suitable ones to obtain economic results for the interest groups and the society in general. In addition, policies and actions that currently lack coherence and continuity are evaluated, which influence entrepreneurs and businessmen who lose dynamism and initiative, reflections and limitations on investment, the market, innovation and low levels of Productivity and competitiveness, the product of the lack of strategic management with an international vision, with a structure that does not guarantee propitious, that is to say, are not given the conditions to be the alternative expected to be subject to the implementation of protectionist policies.La preocupación creciente de las economías por alcanzar índices de crecimiento favorables se ha constituido en un reto constante, por lo que se pretende presentar el desarrollo de clústeres como alternativas para alcanzar el crecimiento regional. Se recurre a un método analítico que compara diversas teorías e identificar las más convenientes para obtener resultados beneficiosos para los grupos de interés y a la sociedad en general. Además, se evalúan políticas y acciones que actualmente muestran poca coherencia y continuidad, que influyen en emprendedores y empresarios quienes pierden dinamismo e iniciativa, reflejadas en limitaciones en la inversión, mercado, innovación y bajos índices de productividad y competitividad, producto de la carencia de una gestión estratégica con visión internacional, con una estructura que no garantiza propicia, es decir, no están dadas las condiciones para ser la alternativa esperada por estar supeditados a que se implementen políticas proteccionistas.A preocupação crescente das economias para alcançar taxas de crescimento favoráveis tornou-se um desafio constante, por isso, pretende-se introduzir o desenvolvimento do clúster como alternativas para alcançar o crescimento regional.

Authors: Fernández Robin Cristóbal , Santander Astorga Paulina , Yáñez Martínez Diego 
Published: February 2019

This Article of scientific and technological research examines conditioning factors that affect female entrepreneurship in Chile through a study of the formal and informal constraints of institutional economic theory and of differences in women’s experiences with entrepreneurship compared to those of male entrepreneurs. A sample of respondents from Chile was selected, and GEM Adult Population Survey data for the period 2011-2015 were used. The results highlight the influence of informal factors on male and female entrepreneur as perceptions of entrepreneurial capabilities and networking. Additionally, being a student was found to have a negative effect on both genders, while family role has a negative effect on the probability for women to undertake.Este artículo de investigación científica examina factores condicionantes que afectan el emprendimiento femenino en Chile a través de un estudio de las limitaciones formales e informales de la teoría económica institucional y de lasdiferencias en las experiencias de las mujeres emprendedoras en comparación con las de sus pares masculinos. Se seleccionó una muestra de encuestados chilenos y se utilizaron los datos de la Encuesta de Población Adulta deGEM para el período 2011-2015. Los resultados indican la influencia de los factores informales en ambos sexos, como percepción de las capacidades empresariales y la creación de redes. Además, se evidenció que ser estudiantetenía un efecto negativo en ambos sexos, mientras que el papel de la familia tiene un efecto negativo en la probabilidad de que las mujeres emprendan.Este artigo da pesquisa científica e tecnológica examina os fatores condicionantes que afetam o empreendedorismo feminino no Chile através de um estudo das restrições formais e informais da teoria econômica institucional e das diferenças nas experiências das mulheres com o empreendedorismo em comparação com os empresários do sexo masculino.

A Modern városok program újraiparosítási törekvései
Authors: Lux Gábor 
Published: February 2019

A tanulmány célja a 2015-ben indult Modern városok program (MVP) iparfejlesztési elképzeléseinek kritikai elemzése a hazánkban kialakult függő piacgazdasági modell és a tartós gyengeségekkel küzdő fejlesztéspolitikai intézményrendszer tükrében. A gazdasági válság utáni Magyarországon a főáramú fejlesztéspolitikák kudarca, az ország gyenge felzárkózási teljesítménye növekvő érdeklődést eredményezett az alternatív gazdaságfejlesztési receptek iránt. Az új teret nyert developmentalista felfogás visszanyúl az erős állami beavatkozás ideájához, ezt azonban paradox módon olyan környezetben teszi, amelyben a gazdaság jelentős hányada külföldi beruházók kezében van, a hazai fejlesztéspolitika eszköz- és intézményrendszere pedig tartós és öröklődő gyengeségekkel küzd.
A kormány és a fejlesztésre kijelölt megyei jogú városok külön megállapodásain nyugvó, uniós forrásokat újraelosztó Modern városok program projektszemléletű, vonásaiban a francia és a lengyel tervszerződésekhez hasonló (de azoknál gyengébb és esetlegesebb) fejlesztési eszközként, az új fejlesztési filozófia megtestesítőjeként jelent meg az állami cselekvésben. A program, bár elsősorban városfejlesztési eszköz, jelentős számban tartalmaz újraiparosításra irányuló vagy azt támogató fejlesztési célokat (77 projekt).
A program elképzeléseit jelentős regionális különbségek fémjelzik. Az ország nyugati felében inkább a hagyományos fejlesztési eszközök alkalmazása és néhány tudásintenzív tevékenység letelepítésére irányuló törekvés figyelhető meg; a Dél-Alföldön és környezetében az endogén növekedési modell számára is kedvező komplex iparfejlesztési célok kerültek előtérbe; az ország ipari perifériáin azonban egyáltalán nem került sor igazi áttörést sejtető, előremutató fejlesztési célok megfogalmazására. Feltehető, hogy az MVP nyertesei elsősorban a már iparosodott vagy újraiparosodó térségek lesznek; a területi különbségek mérséklődése helyett a különbségek további növekedésére számíthatunk.
Os verbos ir, dever e poder e seus infinitivos: sintaxe interna e externa / The verbs ir (‘go’), dever (‘must’) and poder (‘can/may’) and their infinitives: internal and external syntax
Authors: Resende Mauricio Sartori , Araújo-Adriano Paulo Ângelo de 
Published: February 2019

Resumo: Este trabalho investiga as propriedades sintáticas internas (isto é, a constituição morfofonológica) e externas (ou seja, a relação com outros constituintes da sentença) dos infinitivos que ocorrem com os verbos ir, dever e poder. Mais especificamente, este artigo mostra que o comportamento sintático e semântico desses infinitivos é capturado pela depreensão de três propriedades principais, a saber, (i) formação de uma única unidade sintática com ir, dever e poder, (ii) dependência morfossintática com o verbo auxiliar/modal que lhe subcategoriza, (iii) interpretação de evento em potencial. Assim, partindo desse recorte, o presente estudo propõe uma análise à luz do quadro da Morfologia Distribuída (HALLE; MARANTZ, 1993) e, alternativamente, uma análise que assume os pressupostos do Programa Minimalista (CHOMSKY, 1993), com o objetivo de mostrar que, independentemente da teoria que se assume, com base no mesmo conjunto de traços, os fenômenos empíricos que subjazem à relação entre ir, dever e poder e seus infinitivos pode ser capturada. Palavras-chave: infinitivos; verbo auxiliar; verbo modal.Abstract: This paper investigates both internal (i.e. the morphophonological structures) and external (i.e. the relation with the other constituents of the sentence) syntactic properties of infinitives occurring with the verbs ir (‘go’) dever (‘must’) and poder (‘can/may’). More specifically, this paper shows that the syntactic and semantic behavior of those infinitives is captured by three major properties, namely, (i) the constituency of a single syntactic unit with ir, dever and poder, (ii) the morphosyntactic dependency on the auxiliary/modal that is selected, (iii) the reading of potential event. Thus, departing from those properties, the present study proposes a Distributed Morphology-based approach (HALLE; MARANTZ, 1993) analysis and, alternatively, a Minimalist-based approach (CHOMSKY, 1993) analysis, in order to show that, regardless the theory assumed, by considering the same group of features, the empirical phenomena underlying the relation between ir, dever and poder and their infinitives can be captured.Keywords: infinitives; auxiliary verb; modal verb.
A prospective study of number of attempts required in conventional image guided transthoracic fine needle aspiration for pulmonary lesions
Authors: Sagar Ramesh C. , Kumar K. V. Veerendra , Madhu S. D. , Malathi M. 
Published: February 2019

Background: With the established role of computed tomography (CT) screening for lung cancer, and the broad application of high-resolution CT, the solitary pulmonary nodule (SPN) are increasingly detected. The discovery rate of pulmonary lesions is evidently elevated these days: most of them are benign, but some of them are lung cancer. Lung cancer remains the leading cause of cancer deaths worldwide. The diagnosis of this pulmonary lesion is difficult and obtaining tissue samples to conduct pathology examination is the key point. Image guided transthoracic fine needle aspiration (TTFNA) of lung lesions is a well established, safe, and rapid method for achieving a definitive diagnosis for most lung lesions.Methods: TTFNA were performed in 160 patients attended the OPD and admitted due to pulmonary lesions between September 2016 and May 2017. After detailed characterization by computed tomography and compared with chest x-ray, TTFNA was done. Number of attempts, reasons for multiple attempts, and final FNAC diagnosis were recorded.Results: When CT guidance was used sufficient material was obtained in 91.03% of patients, but with USG guidance insufficient material was reason for repeated attempts in nearly 25.25% of cases. Bloody aspirate was reason in total 13.54% patients and there was no significant difference between CT guidance and USG guidance (14.29% v/s 13.13% respectively). Again only inflammatory cells was reason for repeated attempts, in CT guidance 8.93% and in USG guidance 20.20%, attributed to localization of needle in both techniques.Conclusions: CT guided FNAC should be considered in diagnosis of lung lesions if computerized tomography is not contraindicated. Further, routine need for advanced imaging techniques like 3D computerized tomographic study for localizing lesions in lung to reduce the number of attempts should be considered.
Effectiveness of Virtual Reality Technology to teach Gen Z students about Construction Safety: A Pilot Study
Authors: Ghosh Dastider Swarnali 
Published: February 2019

This pilot study was conducted to investigate the effectiveness of using Virtual Reality (VR) technologies to teach the "Generation Z" (GenZ) students about construction safety as part of the Construction Science and Management (CSM) program at Tuskegee University. Research shows that the "Technology Generation" or GenZ students are not satisfied with the traditional pedagogical methodology; rather they demand new hands-on tech-heavy immersive learning experience. In this direction, Virtual Reality is propelling profound technological renovation within the practice of Architecture, Engineering, and Construction (A/E/C) industry allowing for a new pedagogical approach. In this approach, students learn from a 3D dimensional smart environment to help identify the construction safety challenges, instead of going to the potentially dangerous construction sites. This approach has been proven to positively influence construction education in many ways, including enhanced awareness and hazards recognition, in general. This research aimed to test this theory to teach GenZ students enrolled at the CSM program at Tuskegee University. For this study, GenZ students were first exposed to traditional 2D teaching aid demonstrating construction hazards and then the multiple Virtual Reality (VR) serious games. Their response was recorded through written reports, oral interviews and a survey followed by a comparative analysis between 2D visual aid and VR technologies to test the theory as mentioned earlier. These results indicated that the GenZ students greatly welcomed VR Construction Safety exercises more than traditional 2D visual aids and were interested in exploring more.
Pin-ended column buckling load is 2.73% lower than Euler's
Authors: Al-Najmi Abdulqader Said 
Published: February 2019

A verification calculation was aimed at further proving that the least critical load gives the Euler buckling load for a pin-ended column to be : Pcr=(PI)2*EI/L2. Selecting a parabolic function for this purpose, that meets the boundary conditions and is almost exactly similar to the symmetrical function sin(x). It was expected to obtain a critical load that is larger than the load given by the sine function. The parabolic function produced LOWER CRITICAL LOAD by about 2.73%.
