Regional growth and SMEs in Brazil:a spatial panel approach

Cravo T. A., Becker B. and Gourlay A. Regional growth and SMEs in Brazil: a spatial panel approach, Regional Studies. This paper examines economic growth for a panel of 508 Brazilian micro-regions for the period 1980-2004, using spatial econometrics and paying particular attention to the importance of small and medium-sized enterprises (SMEs). The findings indicate the presence of spatial dependence in the process of economic growth and the existence of two spatial regimes in Brazil. The human capital level of the whole population is an important growth determinant, but does not generate positive spillovers. Furthermore, human capital embodied in SMEs is more important than the size of this sector for regional growth and SME activity generates positive spatial spillovers. © 2014 © 2014 Regional Studies Association.

Uma investigação das sequências de fase Hebbianas descritas como grafos de assembleias neuronais

Hebb proposed that synapses between neurons that fire synchronously are strengthened, forming cell assemblies and phase sequences. The former, on a shorter scale, are ensembles of synchronized cells that function transiently as a closed processing system; the latter, on a larger scale, correspond to the sequential activation of cell assemblies able to represent percepts and behaviors. Nowadays, the recording of large neuronal populations allows for the detection of multiple cell assemblies. Within Hebb’s theory, the next logical step is the analysis of phase sequences. Here we detected phase sequences as consecutive assembly activation patterns, and then analyzed their graph attributes in relation to behavior. We investigated action potentials recorded from the adult rat hippocampus and neocortex before, during and after novel object exploration (experimental periods). Within assembly graphs, each assembly corresponded to a node, and each edge corresponded to the temporal sequence of consecutive node activations. The sum of all assembly activations was proportional to firing rates, but the activity of individual assemblies was not. Assembly repertoire was stable across experimental periods, suggesting that novel experience does not create new assemblies in the adult rat. Assembly graph attributes, on the other hand, varied significantly across behavioral states and experimental periods, and were separable enough to correctly classify experimental periods (Naïve Bayes classifier; maximum AUROCs ranging from 0.55 to 0.99) and behavioral states (waking, slow wave sleep, and rapid eye movement sleep; maximum AUROCs ranging from 0.64 to 0.98). Our findings agree with Hebb’s view that neuronal assemblies correspond to primitive building blocks of representation, nearly unchanged in 10 the adult, while phase sequences are labile across behavioral states and change after novel experience. The results are compatible with a role for phase sequences in behavior and cognition

The influence of interhemispheric connections on ongoing and evoked orientation preference maps and spiking activity in the cat primary visual cortex

In the primary visual cortex, neurons with similar physiological features are clustered together in columns extending through all six cortical layers. These columns form modular orientation preference maps. Long-range lateral fibers are associated to the structure of orientation maps since they do not connect columns randomly; they rather cluster in regular intervals and interconnect predominantly columns of neurons responding to similar stimulus features. Single orientation preference maps – the joint activation of domains preferring the same orientation - were observed to emerge spontaneously and it was speculated whether this structured ongoing activation could be caused by the underlying patchy lateral connectivity. Since long-range lateral connections share many features, i.e. clustering, orientation selectivity, with visual inter-hemispheric connections (VIC) through the corpus callosum we used the latter as a model for long-range lateral connectivity. In order to address the question of how the lateral connectivity contributes to spontaneously generated maps of one hemisphere we investigated how these maps react to the deactivation of VICs originating from the contralateral hemisphere. To this end, we performed experiments in eight adult cats. We recorded voltage-sensitive dye (VSD) imaging and electrophysiological spiking activity in one brain hemisphere while reversible deactivating the other hemisphere with a cooling technique. In order to compare ongoing activity with evoked activity patterns we first presented oriented gratings as visual stimuli. Gratings had 8 different orientations distributed equally between 0º and 180º. VSD imaged frames obtained during ongoing activity conditions were then compared to the averaged evoked single orientation maps in three different states: baseline, cooling and recovery. Kohonen self-organizing maps were also used as a means of analysis without prior assumption (like the averaged single condition maps) on ongoing activity. We also evaluated if cooling had a differential effect on evoked and ongoing spiking activity of single units. We found that deactivating VICs caused no spatial disruption on the structure of either evoked or ongoing activity maps. The frequency with which a cardinally preferring (0º or 90º) map would emerge, however, decreased significantly for ongoing but not for evoked activity. The same result was found by training self-organizing maps with recorded data as input. Spiking activity of cardinally preferring units also decreased significantly for ongoing when compared to evoked activity. Based on our results we came to the following conclusions: 1) VICs are not a determinant factor of ongoing map structure. Maps continued to be spontaneously generated with the same quality, probably by a combination of ongoing activity from local recurrent connections, thalamocortical loop and feedback connections. 2) VICs account for a cardinal bias in the temporal sequence of ongoing activity patterns, i.e. deactivating VIC decreases the probability of cardinal maps to emerge spontaneously. 3) Inter- and intrahemispheric long-range connections might serve as a grid preparing primary visual cortex for likely junctions in a larger visual environment encompassing the two hemifields.

Documentação automatizada de APIs com tutoriais gerados a partir do Stack Overflow

One of the most common forms of reuse is through API usage. However, one of the main challenges to effective usage is an accessible and easy to understand documentation. Several papers have proposed alternatives to make more understandable API documentation, or even more detailed. However, these studies have not taken into account the complexity of understanding of the examples to make these documentations adaptable to different levels of experience of developers. In this work we developed and evaluated four different methodologies to generate tutorials for APIs from the contents of Stack Overflow and organizing them according to the complexity of understanding. The methodologies were evaluated through tutorials generated for the Swing API. A survey was conducted to evaluate eight different features of the generated tutorials. The overall outcome of the tutorials was positive on several characteristics, showing the feasibility of the use of tutorials generated automatically. In addition, the use of criteria for presentation of tutorial elements in order of complexity, the separation of the tutorial in basic and advanced parts, the nature of tutorial to the selected posts and existence of didactic source had significantly different results regarding a chosen generation methodology. A second study compared the official documentation of the Android API and tutorial generated by the best methodology of the previous study. A controlled experiment was conducted with students who had a first contact with the Android development. In the experiment these students developed two tasks, one using the official documentation of Android and using the generated tutorial. The results of this experiment showed that in most cases, the students had the best performance in tasks when they used the tutorial proposed in this work. The main reasons for the poor performance of students in tasks using the official API documentation were due to lack of usage examples, as well as its difficult use.

Media diversity as a guarantee to cultural diversity: the promotion of identities from an international law approach

This article deals with several international instruments which provide legal guarantees for media diversity, which is essential for the promotion of cultural diversity. Based on several articles of the Convention of cultural diversity, the General Comment of the Committee on Economic, Social and Cultural Rights No. 21 on the right to take part in cultural life, as well as the work of the UN Independent Expert on Cultural Rights, this article aims to identify legal tools for the establishing of measures promoting cultural diversity in the media. This article looks at the case study of Honduran Garifuna community radios. It emphasizes the importance of taking into account the economic aspects of cultural and communicational rights.

Valtatien 12 parantaminen välillä Uusikylä–Mankala : Yleissuunnitelma

Valtatie 12 on yksi Suomen tärkeimmistä poikittaisyhteyksistä sekä henkilöliikenteelle että elinkeinoelämän kuljetuksille. Se toimii merkittävänä raskaan liikenteen kuljetusreittinä Länsi- ja Kaakkois-Suomen välillä sekä myös yhteytenä satamiin ja rajanylityspaikoille. Yhteysväli Lahti–Kouvola on keskeinen osa Salpausselän liikennekäytävää ja kuuluu Euroopan laajuiseen kattavaan liikenneverkkoon (TEN-T). Tien varressa on runsaasti teollisuutta ja tie toimii Lahden ja Kouvolan kaupunkiseutujen työmatkaliikenteen yhteytenä, joka näkyy vilkkaana arkiliikenteenä. Valtatielle 12 on Uudenkylän ja Tillolan välille on laadittu samanaikaisesti ja samassa suunnitteluprosessissa kaksi yleissuunnitelmaa väleille Uusikylä–Mankala ja Mankala–Tillola. Tämän Uusikylä–Mankala yleissuunnitelman suunnittelualue rajautuu lännessä Nastolan Uudenkylän eritasoliittymään ja idässä Mankalaan Iitin kunnan länsirajan tuntumaan. Suunnittelualueen pituus on noin 10 kilometriä ja se sijoittuu Päijät-Hämeen ja Kymenlaakson maakuntien sekä Lahden kaupungin (entinen Nastola) ja Iitin kunnan alueille. Yleissuunnitelmassa on selvitetty ensin valtatieverkon puutteet ja ongelmat sekä palvelutasotavoitteet. Tämän jälkeen on suunniteltu valtateiden ja muiden väylien periaateratkaisut sekä selvitetty niin tilantarve, suhde ympäröivään maankäyttöön ja vaikutukset. Myös mahdollisuudet hankkeen vaiheittain toteuttamiseksi on käsitelty. Yleissuunnitelmassa on tarkennettu ratkaisuja, vaikutusarviota ja liikenteen, maankäytön ja ympäristön lähtötietoja. Päätavoitteena on ollut selvittää pääteiden ja muun tie- ja katuverkon kehittämisen periaatteet niin, että nykyiset palvelutasopuutteet saadaan poistettua ja valtatie 12 vastaa sille asetettuja vaatimuksia liikenteen sujuvuuden ja turvallisuuden kannalta. Osana suunnitelmaa on esitetty toimenpiteet meluhaittojen torjumiseksi ja ympäristövaikutusten lieventämiseksi. Valtatie 12 parannetaan korkealuokkaiseksi ja laatutasoltaan yhtenäiseksi keskikaiteelliseksi ja eritasoliittymin varustetuksi ohituskaistatieksi noin 10 kilometrin matkalla tarvittavine tie-, katu- ja liittymäjärjestelyineen. Valtatien 12 käytävään muodostuu jatkuva rinnakkaistie. Lisäksi tehdään meluntorjuntaa ja pohjavesialueet suojataan.

Valtatien 13 parantaminen välillä Lappeenranta–Nuijamaa : Hanke-esite

Valtatien 13 osuus Lappeenrannasta Nuijamaalle kuuluu Euroopan komission päättämään Suomen kattavaan liikenneverkkoon TEN-T. Tieosuus on maan toiseksi tärkein kansainvälisen liikenteen yhteys kuljetuksille ja henkilöliikenteelle. Valtatie 13 kulkee maan poikki länsirannikolta Kokkolasta Lappeenrantaan ja siitä edelleen Nuijamaan rajanylityspaikan kautta Venäjän puolelle Viipuriin. Valtatie 13 palvelee osaltaan myös paikallista liikkumista Nuijamaan kylätaajaman ja Lappeenrannan välillä. Erityisesti Mustolan alueelle ja myös osittain Nuijamaan raja-aseman läheisyyteen suunnitellut ja jo osittain toteutuneet maankäytön kaupalliset palvelut lisäävät voimakkaasti kasvaessaan myös seudullista liikennettä suunnitteluosuudella. Nuijamaan raja-asema on ollut Suomen itärajan toiseksi vilkkain tieliikenteen rajanylityspaikka. Rajanylityspaikan kautta kulki vuonna 2015 noin miljoona ajoneuvoa ja 2,4 miljoonaa matkustajaa. Venäjän ja Suomen valtioiden välisen liikenteen kasvu on ollut voimakkainta Kaakkois-Suomessa ja sille on edelleen perusteltuja kasvuodotuksia, vaikka viime aikoina liikenne on merkittävästi vähentynyt. Myös tavaraliikenteellä on potentiaalia lisääntyä viimeaikaisesta. Suunnittelualueeseen kuuluu valtatien 13 (16,6 km) lisäksi valtatien 6 länsipuolinen valtatien 13 jatke Karjalantie (mt 3821) (1,2 km). Yleissuunnitelmassa on selvitetty valtatien 13 puutteet ja ongelmat, palvelutasotavoitteet, valtatien 13 ja muiden väylien periaateratkaisut tilantarpeineen, suhde ympäröivään maankäyttöön, vaikutukset sekä mahdollisuudet vaiheittain toteuttamiseksi. Päätavoitteena on ollut selvittää valtatien 13 ja muiden väylien kehittämisen periaatteet niin, että palvelutasopuutteet saadaan poistettua ja valtatie 13 vastaa sille asetettuja vaatimuksia liikenteen sujuvuuden ja turvallisuuden kannalta. Osana suunnitelmaa on esitetty toimenpiteet meluhaittojen torjumiseksi ja ympäristövaikutusten lieventämiseksi. Valtatie 13 parannetaan nykyisellä paikallaan korkealuokkaiseksi nelikaistaiseksi valtatieksi tarvittavine tie-, katu- ja liittymäjärjestelyineen. Vastakkaiset ajosuunnat on erotettu toisistaan rakenteellisesti ja kaikki valtatien liittymät ovat eritasoliittymiä.

La gran decisión: (Caso de estudio en finanzas)

En una agradable mañana del día 3 de marzo de 1995, se encontraba el doctor Miguel Echavarría, presidente de la sociedad "Los Hilos Sintéticos SA", presentando los Estados Financieros del último año y las proyecciones ante la Asamblea General de Accionistas, cuando de manera súbita el doctor Jesús Matías, accionista mayoritario, intervino un poco ofuscado diciendo que según su apreciación, en el informe anual lo que se presentaba era nuevamente una crisis financiera y que si no se tenía un plan de acción definido para su solución en ese momento, le exigía que convocara a una nueva Asamblea el viernes de la semana próxima, para presentarlo, o de lo contrario se deberían tomar de inmediato medidas drásticas.
