Planning for a Qatar Without Oil: Tourism and Economic Diversification, a Battle of Perceptions
Qatar's long-term strategy is to plan for when the country will not be dependent upon oil and gas reserves. The strategy focuses on export diversification through development of service industries, including finance, knowledge-based sectors and tourism. This is a sensible option given the availability of capital and paucity of non-energy resources. To date the success in attracting tourists has...


Interformat competition in the grocery retailing
In the last few years, we have seen significant changes in the Italian retail environment which suggest that the patterns of retailing competition are more complex than in the past. In order to expand their target market in a context of economic recession, retailers are implementing new strategies aimed to stimulate the switching between different store formats. As a result, store formats are g...
Tecnologia da informação e comunicação enquanto ferramenta mediadora no auxílio à educação
A tecnologia da informação e da comunicação (TIC’s) está cada vez mais inserida nos mais variados meios e segmentos e no educacional não é diferente. Na educação as TIC’s vêm sendo utilizadas inicialmente como meio de gerenciar as instituições educacionais e seus processos, porém, enquanto meio para oportunizar aperfeiçoamento dos processos de ensino e aprendizagem ainda tem m...


Os direitos fundamentais e o neoconstitucionalismo
O presente trabalho versa sobre os aspectos mais relevantes dos direitos fundamentais na atual fase do constitucionalismo denominado de neoconstitucionalismo. O estudo traz em seu corpo compilações acerca do conceito, da historicidade e das principais características desses importantes institutos jurídicos no atual cenário constitucional da era pós-moderna. O neoconstitucionalismo ganhou ...
Arte-educação: uso de imagens no desenvolvimento do saber
O objetivo desse artigo é incentivar não apenas educadores ligados à área artística, como também os demais educadores a fim de que os mesmos utilizem imagens, ou seja, estímulos visuais como recurso para o desenvolvimento do saber. Identificar em qual contexto a imagem é utilizada em sala de aula, bem como verificar se os docentes receberam alguma formação em seus cursos de origem par...

Persistência, aprendizado contínuo, trabalho e paixão: um pouco mais sobre empreendedorismo
A proposta deste artigo é fazer algumas reflexões sobre o fato que, todos podemos, ou ao menos, buscamos ter nosso negócio próprio. Sem pretenção de apresentar ideias inovadoras, busca-se mostrar aqui com um caso real, refletir sobre a coerência existente entre teoria e prática. Ou seja, quando observamos qualquer empreendimento eficaz, dois aspectos sobressaem: a necessidade de se conh...

Stochastic Efficiency Analysis with a Reliability Consideration
Stochastic Data Envelopment Analysis (DEA) models have been introduced in the literature to assess the performance of operating entities with random input and output data. A stochastic DEA model with a reliability constraint is proposed in this study that maximizes the lower bound of an entity's efficiency score with some pre-selected probability. We define the concept of stochastic efficiency ...
Efficiency-free characterizations of the Kalai–Smorodinsky bargaining solution
Roth (1977) axiomatized the Nash (1950) bargaining solution without Pareto optimality, replacing it by strong individual rationality in Nash’s axiom list. In a subsequent work (Roth, 1979) he showed that when strong individual rationality is replaced by weak individual rationality, the only solutions that become admissible are the Nash and the disagreement solutions. In this paper I derive an...

Copula-based dependence between frequency and class in car insurance with excess zeros
A bonus-malus system calculates the premiums for car insurance based on the previous claim experience (class). In this paper, we propose a model that allows dependence between the claim frequency and the class occupied by the insured using a copula function. It also takes into account zero-excess phenomenon. The maximum likelihood method is employed to estimate the model parameters. a small sim...
Testing the value of probability forecasts for calibrated combining
We combine the probability forecasts of a real GDP decline from the US Survey of Professional Forecasters, after trimming the forecasts that do not have “value”, as measured by the Kuiper Skill Score and in the sense of Merton (1981). For this purpose, we use a simple test to evaluate the probability forecasts. The proposed test does not require the probabilities to be converted to binary f...

Forecasting economic activity with targeted predictors
In this paper we explore the forecasting performances of methods based on a pre-selection of monthly indicators from large panels of time series. After a preliminary data reduction step based on different shrinkage techniques, we compare the accuracy of principal components forecasts with that of parsimonious regressions in which further shrinkage is achieved using the General-To-Specific appro...
Short-term forecasting of GDP with a DSGE model augmented by monthly indicators
Dsge models are useful tools for evaluating the impact of policy changes, but their use for (short-term) forecasting is still in its infancy. Besides theory-based restrictions, the timeliness of data is an important issue. Since dsge models are based on quarterly data, they suffer from the publication lag of quarterly national accounts. In this paper we present a framework for the short-term fo...
Marked point process hotspot maps for homicide and gun crime prediction in Chicago
Crime hotspot maps are a widely used and successful method of displaying spatial crime patterns and allocating police resources. However, hotspot maps are often created over a single timescale using only one crime type. In the case of short-term hotspot maps that utilize several weeks of crime data, risk estimates suffer from a high variance, especially for low frequency crimes such as homicide...
Line, line, everywhere a line: Cultural considerations for waiting-line managers
Given the trend of increasing business globalization, management teams of multinational companies have taken steps to better understand consumers, local business partners, and local governments. Local queueing preferences present managers with additional challenges and opportunities in international markets. The world may be ‘flat,’ but it is foolish to believe that all cultures perceive li...
