O empreendedorismo tem sido um tema recorrente nas análises de incubadoras de empresas. O crescimento das incubadoras no Brasil tem se mantido constante desde o final dos anos 1990, mostrando-se um fenômeno relevante para a criação de emprego e renda. Com o objetivo de avaliar o papel das incubadoras na formação empreendedora, tendo em vista a análise feita por McDougall e Alli (2003) sobre o empreendedorismo internacional, este trabalho busca compreender as perspectivas das empresas emergentes para sustentar-se no mercado global. O trabalho está estruturado em quatro seções. A primeira seção apresenta a temática do empreendedorismo e a metodologia adotada para esta análise; a segunda apresenta o referencial teórico, destacando os conceitos de empreendedorismo internacional; a terceira parte descreve o papel das incubadoras a partir de uma análise documental sobre o tema; a quarta parte aponta perspectivas para a formação empreendedora nas incubadoras de empresas.

Se considera a los postes de hormigón armado un elemento indispensable para la distribución de energía eléctrica, también son parte de nuestro ornamento. Como breve reseñapuedo indicar que la idea del negocio nació, para satisfacer la necesidad de encontrar una fábrica de postes de hormigón que cuente con stock y con entrega oportuna a los clientes ubicados en la zona Austral.Al existir una sola fábrica se generó una escasez del producto, para cubrir la demanda se debe buscar en otras ciudades, lo que encarece el precio del producto debido al incremento del costo del transporte, además seproduce retraso en la construcción de las obras eléctricas. Con este proyecto se analizó la factibilidad de instalaruna fábrica de postes de hormigón armado, se cuantificó la inversión que demandaráempezar la producción y venta de los productos. Se comercializará postes de 10 y 12 metros de longitud, debido a que son los más utilizados en las empresas eléctricas, telefonía, internet y tv cable.

Sono stati analizzati i circuiti neurali addetti all'elaborazione matematica, a partire da quelli di start-up neurocognitivo per l'apprendimento del numero e del calcolo, capacità innate e già presenti alla nascita. I protagonisti sono il sistema della stima approssimativa del numero e quello di individuazione degli oggetti multipli e, spesso, le difficoltà che si incontrano durante un compito matematico (o la lentezza per portarlo a termine) sono date dalla difficile interazione tra questi e le loro sottocomponenti, continuamente riprogrammate dall'esecutivo centrale per poter supervisionare i processi di problem solving. Per la costruzione e lo sviluppo del calcolo più elevato, occorrono alcune capacità di base come il concetto di corrispondenza biunivoca, quello di ordinamento di un insieme, di maggioranza, di raddoppio e di dimezzamento, per mezzo delle quali ogni procedura si può ridurre ad una serie di operazioni più semplici. Queste funzioni vengono controllate e coordinate dal Sistema Attentivo Esecutivo che presiede tutte le attività di problem solving. I ragazzi che presentano deficit altamente specifici in una o più abilità matematiche di base vengono definiti discalculici e tra i loro tratti caratteristici vi sono l'incapacità di comprendere le numerosità, i principi delle operazioni e di elaborare strategie risolutive adatte ad ogni esercizio. Non tutti i ragazzi che presentano difficoltà in matematica sono discalculici: a tal proposito ho svolto una sperimentazione didattica in 10 classi di un I.T.I.S. , per cercare di capire se i concetti reputati consolidati alla scuola secondaria di 1° grado, lo sono realmente in quella di 2° e per mostrare le diverse tipologie di errori compiuti dai ragazzi clinici e non. I risultati sono stati largamente al di sotto delle aspettative, anche negli esercizi in cui è stato permesso l'uso della calcolatrice, lasciandomi presagire che gli errori commessi siano perlopiù di concetto piuttosto che di calcolo.

Government call centers (311) were first created to reduce the volume of non-emergency calls that were being placed to emergency 911 call centers. The number of 311 call centers increased from 57 in 2008 to about 300 in 2013. Considering that there are over 2,700 municipal government units across the United States, the adoption rate of the 311 centers is arguably low in the country. This dissertation is an examination of the adoption of 311 call centers by municipal governments. My focus is specifically on why municipal governments adopt 311 and identifying which barriers result in the non-adoption of 311 call centers. This dissertation is possibly the first study to examine the adoption of 311 call centers in the United States. ^ The dissertation study has identified several significant factors in the adoption and non-adoption of 311 government call centers. The following factors were significant in the adoption of 311 government call centers: managerial support, financial constraints, organizational responsiveness, strategic plan placement, and technology champion. The following factors were significant barriers that resulted in the non-adoption of a 311 government call center; no demand from citizens, start up costs, annual operating costs, unavailability of funding, and no obvious need for one. ^ If local government entities that do not have a 311 government call center decide to adopt one, this study will help them identify the conditions that need to be in place for successful adoption to occur. Local government officials would first need to address the barriers in setting up the 311 call centers. ^

In this paper, the start-up process is split conceptually into four stages: considering entrepreneurship, intending to start a new business in the next 3 years, nascent entrepreneurship and owning-managing a newly established business. We investigate the determinants of all of these jointly, using a multinomial logit model; it allows for the effects of resources and capabilities to vary across these stages. We employ the Global Entrepreneurship Monitor database for the years 2006–2009, containing 8269 usable observations from respondents drawn from the Lower Layer Super Output Areas in the East Midlands (UK) so that individual observations are linked to space. Our results show that the role of education, experience, and availability of ‘entrepreneurial capital’ in the local neighbourhood varies along the different stages of the entrepreneurial process. In the early stages, the negative (opportunity cost) effect of resources endowment dominates, yet it tends to reverse in the advanced stages, where the positive effect of resources becomes stronger.

Attention Deficit-Hyperactivity Disorder is a disease that affects 3 to 5 percent of children globally. Many of those live in areas with very few or no medical professionals qualified to help them. To help assuage this problem a system was developed that allows physicians to accompany their patient’s progress and prescribe treatments. These treatments can be drugs or behavioral exercises. The behavioral exercises were designed in the form of games in order to motivate the patients, children, for the treatment. The system allows the patients to play the prescribed games, under the supervision of their tutors. Each game is designed to improve the patient’s handling of their disease through training in a specific mental component. The objective of this approach is to complement the traditional form of treatment by allowing a physician to prescribe therapeutic games and maintaining the patients under supervision between their regular consultations. The main goal of this project is to provide the patients with a better control of their symptoms that with just traditional therapy. Experimental field tests with children and clinical staff, offer promising results. This research is developed in the context of a financed project involving INESC C (Polytechnic Institute of Leiria delegation), the Santo André Hospital of Leiria, and the start-up company PlusrootOne (that owns the project).

Con el proceso de globalización que se evidencia actualmente, el comercio entre países ha sido uno de los factores más relevantes a través del tiempo y Colombia no ha sido excluyente a esta situación. Es por la importancia del asunto, que la Escuela de Administración dentro de sus múltiples proyectos de investigación busca la identificación de oportunidades para PYMES colombianas en mercados extranjeros, específicamente en Estados Unidos, asumiendo los retos que trae consigo un Tratado de Libre Comercio, las implicaciones en cuanto a los procesos de intercambio (importaciones y exportaciones) en sus diversos ámbitos y el impacto que genera dicho proceso en la balanza comercial colombiana. Debido a esto, se ha propuesto el desarrollo de un trabajo de grado que analice el Tratado de Libre Comercio (TLC) entre Colombia y Estados Unidos, enfocándose en los perfiles de cada mercado y las necesidades de los mismos, con el fin de identificar oportunidades generadas desde su puesta en marcha. En busca de un análisis detallado, el trabajo en mención hace énfasis en cinco estados de Estados Unidos (Iowa, Kansas, Kentucky, Luisiana y Maine) y los 32 departamentos de Colombia. Con el objetivo de realizar un análisis más efectivo se tomaron en cuenta las características de cada mercado y su relación comercial. A partir del previo proceso de investigación, se pretende identificar y definir oportunidades comerciales que evidencian una evolución comercial (mayor número de importaciones y exportaciones). Dichas oportunidades identificadas son el resultado de un análisis cualitativo tras desarrollar matrices de los principales diez productos más demandados por los Estados mencionados y los principales productos ofertados por los departamentos colombianos. Gracias a lo que enmarca un TLC dentro de un proceso de negociación, se proyecta identificar según las necesidades de las partes, es decir, oferta y demanda de bienes y/o 9 servicios, cada una de las oportunidades claves para los comerciantes nacionales que se involucran dentro del acuerdo aprobado.

This paper presents a stochastic mixed-integer linear programming approach for solving the self-scheduling problem of a price-taker thermal and wind power producer taking part in a pool-based electricity market. Uncertainty on electricity price and wind power is considered through a set of scenarios. Thermal units are modeled by variable costs, start-up costs and technical operating constraints, such as: ramp up/down limits and minimum up/down time limits. An efficient mixed-integer linear program is presented to develop the offering strategies of the coordinated production of thermal and wind energy generation, aiming to maximize the expected profit. A case study with data from the Iberian Electricity Market is presented and results are discussed to show the effectiveness of the proposed approach.

This paper deals with the self-scheduling problem of a price-taker having wind and thermal power production and assisted by a cyber-physical system for supporting management decisions in a day-ahead electric energy market. The self-scheduling is regarded as a stochastic mixed-integer linear programming problem. Uncertainties on electricity price and wind power are considered through a set of scenarios. Thermal units are modelled by start-up and variable costs, furthermore constraints are considered, such as: ramp up/down and minimum up/down time limits. The stochastic mixed-integer linear programming problem allows a decision support for strategies advantaging from an effective wind and thermal mixed bidding. A case study is presented using data from the Iberian electricity market.

This thesis focuses on the dynamics of underactuated cable-driven parallel robots (UACDPRs), including various aspects of robotic theory and practice, such as workspace computation, parameter identification, and trajectory planning. After a brief introduction to CDPRs, UACDPR kinematic and dynamic models are analyzed, under the relevant assumption of inextensible cables. The free oscillatory motion of the end-effector (EE), which is a unique feature of underactuated mechanisms, is studied in detail, from both a kinematic and a dynamic perspective. The free (small) oscillations of the EE around equilibria are proved to be harmonic and the corresponding natural oscillation frequencies are analytically computed. UACDPR workspace computation and analysis are then performed. A new performance index is proposed for the analysis of the influence of actuator errors on cable tensions around equilibrium configurations, and a new type of workspace, called tension-error-insensitive, is defined as the set of poses that a UACDPR EE can statically attain even in presence of actuation errors, while preserving tensions between assigned (positive) bounds. EE free oscillations are then employed to conceive a novel procedure aimed at identifying the EE inertial parameters. This approach does not require the use of force or torque measurements. Moreover, a self-calibration procedure for the experimental determination of UACDPR initial cable lengths is developed, which consequently enables the robot to automatically infer the EE initial pose at machine start-up. Lastly, trajectory planning of UACDPRs is investigated. Two alternative methods are proposed, which aim at (i) reducing EE oscillations even when model parameters are uncertain or (ii) eliminate EE oscillations in case model parameters are perfectly known. EE oscillations are reduced in real-time by dynamically scaling a nominal trajectory and filtering it with an input shaper, whereas they can be eliminated if an off-line trajectory is computed that accounts for the system internal dynamics.
