Entrepreneurs’ perspectives and perceptions about the conditions offered by the industrial estates of the quadrilátero urbano
O objetivo do artigo consiste em apresentar as principais conclusões de um inquérito aos empresários instalados nas áreas de acolhimento empresarial do Quadrilátero Urbano, designação dada à rede constituída pelos municípios de Barcelos, Braga, Guimarães e Vila Nova de Famalicão. Este inquérito, que foi elaborado no âmbito de um estudo mais vasto de ordenamento dos espaços empresariais destes quatro municípios, procurou identificar o comportamento locativo dos empresários e o seu grau de satisfação em relação às condições oferecidas por estes espaços. O objetivo foi o de perceber onde estavam localizadas as empresas anteriormente, que motivos levaram à sua deslocalização para aquelas áreas, que avaliação os empresários fazem das condições existentes nesses espaços e quais são as suas intenções de localização futura. Os resultados mostram que a maior parte das empresas tinha uma localização difusa (fora de um espaço empresarial), que os empresários têm uma opinião globalmente favorável das condições oferecidas pelos espaços empresariais do Quadrilátero, mesmo considerando a baixa cobertura em termos de infraestruturas e de serviços. Apenas uma minoria dos inquiridos manifestou intenção de se deslocalizar para outros espaços.This article presents the results of a study undertaken in the Quadrilátero Urbano, designation given to a network composed by the municipalities of Barcelos, Braga, Guimarães and Vila Nova de Famalicão, which aimed at assessing how entrepreneurs perceive the conditions offered by the industrial estates located in this territory. The survey is part of a broader planning study and was performed with the purpose of understand the locative behaviour of entrepreneurs. The goal was to perceive where the entrepreneurs were located before, to identify which reason(s) explained their relocation to an industrial estate and to understand their evaluation regarding the conditions offered by the industrial estates. Furthermore, the survey was also implemented to disclose the future locative intentions of the entrepreneurs. The results show that mostly of the enterprises initially had a diffuse location (outside an industrial estate), the entrepreneurs have a general favourable opinion of the conditions offered by the industrial estates, despite the low coverage in terms of facilities and amenities diagnosed. Only a few entrepreneurs intends to relocate to other spaces in the future
An agent-based model as a tool of planning at a sub-regional scale
This paper describes an agent-based model developed to simulate the impact that different planning policies may have in enhancing the attractiveness of the industrial estates located in a network of four municipalities located in the North of Portugal. The policies were simulated using three scenarios that can be distinguished by the municipal level of coordination they are implemented and by the type of action performed. In the model, enterprises are agents looking for a suitable location and the estates attractiveness is based on their level of facilities, amenities, accessibility and in the cost of soil. The coordinated qualification of the industrial estates is the most effective policy to strengthen their attractiveness. It was in this scenario that more industrial estates become attractive and more enterprises relocated. Results also indicate that the promotion of diffused and unqualified industrial estates is an inefficient policy to attract enterprises.Portuguese Foundation for Science and Technology (SFRH/BD/48567/2008 grant
The industrial parks of Quadrilátero Urbano according to the entrepreneurs’ vision
Os parques industriais são espaços que desempenham funções de natureza territorial, económica e ambiental. Um adequado planeamento e gestão são fundamentais para que os parques cumpram essas funções. Em Portugal há poucos estudos sobre o número e as condições oferecidas pelos parques industriais. Neste artigo apresentam-se as principais conclusões de um estudo sobre o comportamento locativo das empresas e as condições oferecidas pelos parques industriais localizados nos municípios de Barcelos, Braga, Guimarães e Vila Nova de Famalicão, que formam a rede do Quadrilátero Urbano. O estudo baseou-se num inquérito aos empresários localizados nos 79 parques identificados nos quatro municípios. Com a realização do estudo pretendeu-se: identificar os motivos e a proveniência das empresas fixadas nos parques industriais; recolher a perceção dos empresários em relação às condições oferecidas pelos parques; e conhecer as futuras intenções locativas dos empresários. Os resultados revelam que a maior parte dos empresários é proveniente de localizações difusas e que a existência de espaço disponível foi o fator que mais influenciou a decisão de deslocalização. O estudo demonstrou ainda que os empresários têm uma opinião satisfatória das condições oferecidas pelos parques e que a maioria deles não tenciona mudar-se para outro local no futuro.Industrial parks perform territorial, economic and environmental functions. A suitable planning and management are key issues so that industrial parks can achieve these functions. In Portugal there are few studies regarding the number and the conditions provided by the industrial parks. In this article, we show the main conclusions of a study focusing on the firms’ location behaviour and on the conditions provided by a set of industrial parks located in the municipalities of Barcelos, Braga, Guimarães and Vila Nova de Famalicão, which form the network known as Quadrilátero Urbano. The study was based on a survey addressed to 79 entrepreneurs located in the industrial parks of these four municipalities. The study had the following objectives: to identify the origin of the firms and the reasons for choosing to be located in the industrial parks; to capture the entrepreneurs’ perception regarding the conditions provided by the parks; and to understand the future locative intentions of the entrepreneurs. The results show that most firms installed in the parks came from diffuse locations. Space availability was the most important factor affecting the relocation decision. The results also revealed a dominant favourable opinion concerning conditions provided by the parks and a general intention of not relocating to another area in the future.(undefined
Range maps and checklists provide similar estimates of taxonomic and phylogenetic alpha diversity, but less so for beta diversity, of Brazilian Atlantic Forest anurans
AbstractMacroecological and biogeographical studies have assumed that range map data should be used only at coarser grains due to false presences (errors of commission) at small grains. This has been explored using mostly species richness, underrepresenting other potentially informative biodiversity metrics. Here, we evaluated these issues by quantifying the extent to which taxonomic and phylogenetic alpha and beta diversity patterns calculated using anuran range maps at three cell sizes (1×1km, 5×5km, and 10×10km) differ from the patterns calculated based on checklists in 14 protected areas along the southern range of the Brazilian Atlantic Forest. We found that range maps and checklists generated reasonably similar spatial richness patterns in all cell sizes (r≥0.80 in all cases) and slightly weaker, but still correlated alpha phylogenetic diversity patterns (0.78≤r≤0.81). We also found that taxonomic (r≤0.76) and phylogenetic (r≤0.68) beta diversities had lower correlations than alpha spatial patterns. Therefore, range maps have value in documenting alpha biodiversity patterns, as well as beta diversity at more marginal levels, for tropical species at scales relevant to local conservation efforts
A new gravitational N-body simulation algorithm for investigation of cosmological chaotic advection
Recently alternative approaches in cosmology seeks to explain the nature of
dark matter as a direct result of the non-linear spacetime curvature due to
different types of deformation potentials. In this context, a key test for this
hypothesis is to examine the effects of deformation on the evolution of large
scales structures. An important requirement for the fine analysis of this pure
gravitational signature (without dark matter elements) is to characterize the
position of a galaxy during its trajectory to the gravitational collapse of
super clusters at low redshifts. In this context, each element in an
gravitational N-body simulation behaves as a tracer of collapse governed by the
process known as chaotic advection (or lagrangian turbulence). In order to
develop a detailed study of this new approach we develop the COsmic LAgrangian
TUrbulence Simulator (COLATUS) to perform gravitational N-body simulations
based on Compute Unified Device Architecture (CUDA) for graphics processing
units (GPUs). In this paper we report the first robust results obtained from

Levantamento da ocorrência da pinta preta dos citrus (Guignardia citricarpa) em Rondônia.
A pinta-preta ou mancha preta é uma doença fúngica que ataca o limoeiro. Sua manifestação é percebida nos frutos de limão que, por estarem danificados, são depreciados no mercado interno e externo. Com o objetivo de realizar um levantamento epidemiológico desta doença no estado de Rondônia, este trabalho resulta de uma ação conjunta entre a Agência de Defesa Agrossilvopastoril de Rondônia – IDARON e a Embrapa Rondônia, para não apenas verificar a existência da doença no estado, mas também determinar o tamanho da sua abrangência dentro dos principais polos produtores de citros no Estado.bitstream/item/46585/1/cot360-citrus.pd
Levantamento da qualidade ambiental do córrego capim puba no município de Goiânia - GO
Water is an essential natural resource for the maintenance and life of humans, however, anthropogenic actions have disrupted aquatic ecosystems and threatened freshwater sources. The objective of this work was to verify the environmental quality of the Capim Puba stream, located in the city of Goiânia, state of Goiás, during the rainy season of 2016. The samples were collected in three sampling points distributed along the course of the creek: 01 located at the source, point 02 at the site of greater anthropic occupation of the stream banks and point 03 at the confluence with the Botafogo Stream. Environmental quality was investigated through the identification of domestic and industrial effluent release points, level of silting, presence of erosion, debris, flora, solid residues and liquid residues, as well as analysis of physical and chemical variables of the aquatic environment. It was possible to notice greater environmental degradation in point 02 due to anthropic occupation. In addition, the adverse impacts were less intense when compared to previous years, revealing a capacity of the autodepuration stream. © 2020 Centro Universitario de Anapolis. All rights reserved
