O mercado político é aquele no qual demandantes e fornecedores negociam políticas públicas de forma semelhante ao que ocorre em mercados econômicos, ou seja, utilizando-se de estratégias políticas. São notáveis os avanços da literatura em discutir a eficiência destas estratégias e sua relação com o desempenho das empresas que as utilizam. No entanto, o desenvolvimento da estrutura e atratividade dos mercados políticos ainda é insipiente, principalmente no sentido de explicar se as estratégias políticas possuem a mesma natureza que as estratégias de mercado, ou seja, se representam o posicionamento da empresa no mercado político (CAVES; PORTER, 1977; PORTER, 1980b; HILLMAN; KEIM, 1995; HILLMAN; HITT, 1999; BONARDI; HILLMAN; KEIM, 2005). Desta forma, o objetivo deste trabalho é analisar a natureza das ações realizadas pelas empresas com a finalidade de descobrir se estas ações se configuram como estratégias propriamente ditas. Para isso, utilizou-se de uma metodologia experimental que, modelada à luz da teoria dos jogos, testou relações causais determinantes do posicionamento de empresas em mercados políticos. Estas relações basearam-se nos conceitos de barreiras de mobilidade e mecanismos de isolamento e foram observadas em relação à saliência da political issue e rotinas organizacionais. As variáveis foram testadas em dois tratamentos experimentais distintos nos quais os sujeitos foram alunos do curso de graduação de Administração, que aleatoriamente compuseram os grupos experimentais. Os resultados das sessões experimentais evidenciaram a existência de posicionamento das empresas em relação às estratégias políticas de acordo com as duas variáveis testadas: as empresas não mudam a estratégia política na presença de rotinas organizacionais estabelecidas e tampouco o fazem quando há saliência da political issue. Estes achados permitem avançar a discussão da estrutura e atratividade dos mercados políticos uma vez que comprovam que mesmo em mercados com outcome não diferenciado como as políticas públicas, as empresas buscam modelar e proteger estratégias únicas na busca pela melhor performance.

It is estimated that the Brazilian karst areas sum about 200.000 km2. The caves, one of the main components of karst, are important windows into the biological studies on hypogean environments. In Rio Grande do Norte are known 563 caves, and 476 of them are in the municipalities of Baraúna, Felipe Guerra, Governador Dix-Sept Rosado, Apodi and Mossoró, the Western region of the State. However, like in the rest of the country, the cave fauna of the State is still poorly understood. This study used data from invertebrates harvested in 47 caves and aimed to analyze the effect of environmental change between the dry and rainy seasons in the communities of cave invertebrates, characterize these communities and evaluate the relationships between morphological and biotic variables of the caves and surroundings, and to define priority areas for conservation of cave environments of the study area from biotic parameters. Strong effects were found in the community structure of cave invertebrates due environmental changes between seasons, with values of total richness, abundance, diversity and ecological complexity significantly higher in the rainy season. It was possible to assess how the morphology of the cave and the external environment variables affect the biotic system, so that the variety of resources, forest cover in the vicinity, the area of the cave and its entrance were the variables that best explained the structure communities of cave invertebrates in the region. High values of total richness of invertebrates (36,62 ± 14,04 spp / cave) and troglomorphic species (61 species, mean 1,77 ± 2,34 spp / cave) were found and, given the biological relevance in the context of the area national and the imminent anthropogenic pressures existing, we defined four priority areas for actions aiming cave biodiversity conservation in the region.

This study presents our research on the discourse of the grotesque in digital media, specifically in two blogs. We rely on the theoretical-conceptual and methodological discourse analysis of the French School. We analyzed a set of posts in the following blogs: Eu Sou Ryca and Cleycianne, and we did it based on some propositions on the discourse of the grotesque by Mikhail Bakhtin (1999a), Muniz Sodré and Raquel Paiva (2002), Wolfgang Kayser (2003) and Mary Russo (2000). The expressions of the grotesque analyzed in the blogs Eu Sou Ryca and Cleycianne result predominantly in humorous effect, obtained by means of irony and parodization, which calls for ridicule and relegation, through a strong tension between the beautiful and the ugly, the socially acceptable and the aberration, the taste for the strange and the aesthetically striking. The grotesque appears initially as a significant feature of ornamental paintings found in Roman caves in the late fifteenth century, and today it can be seen permeating from sculptures, paintings, literary works, talk shows for television, videos hosted in cyberspace, specifically in the collective domain of weblogs. This work seeks to analyze how the discourse of the grotesque constitutes the humorous process in its insertion in cyberspace

Complete albinism is a rare phenomenon that occurs in all vertebrate groups. In bats, albinism has been recorded in several species but this information has not previously been reviewed in detail nor has there been an analysis of its importance. In this study, cases of albinism from the literature are checked and new cases are presented. Complete albinism in bats is documented in eight families, 38 species, and at least 64 individuals (47.4% female female and 52.6% males; n = 38). of these, 39 individuals were observed and/or captured in sheltered roosts, such as caves (51.3%), mines and galleries (20.5%), buildings (17.9%), and hollow-trees and bird boxes (7.7%). Only one albino bat (2.6%) was captured in an external roost (foliage). This individual is the fruit bat, Artibeus planirostris, which is recorded here for the first time. Information on four additional cases of albino individuals of the common vampire bat, Desmodus rotundus, is also presented. It is suggested that sheltered roosts favour survival of albino bars, offering protection against sunlight, water loss, and visually hunting predators.

Dance is regarded as one of the oldest art forms, which is based on evidence from prehistoric paintings found in caves; man expressed himself through body language prior to the development of spoken and written forms of communication. Dance was then used during important events, common to their era and culture, and often in religious rituals, to ensure good harvests - their economic activity. Belly-dance appeared approximately eight thousand years B. C. E. as a sacred dance firstly practiced by priestesses, and after that, it was popularized amongst women from Mesopotamia. Virtually considered an ancient form of physical exercise, it is still practiced by Bedouin women as a preparation for spontaneous delivery. In Brazil, belly-dance is widely practiced and our corporal culture enables its learning and improvement, resulting in professional dancers.

A pitaya é uma cactácea de sub-bosque, originária de florestas tropicais do México e das Américas Central e do Sul, pouco estudada no Brasil, principalmente quanto à sua resposta à intensidade luminosa e adubação. Nesse sentido, realizou-se um experimento objetivando avaliar crescimento e desenvolvimento inicial da pitaya em função da intensidade luminosa e adubação orgânica. O delineamento experimental adotado foi em blocos casualizados, com tratamentos distribuídos em esquema fatorial 5 x 3, referentes, respectivamente, aos níveis de adubação orgânica (0; 5; 10; 20 e 30 L de esterco bovino cova-1) e aos percentuais de luz (0; 50 e 75% de sombreamento), com quatro repetições. Foram avaliados semanalmente diâmetro do cladódio (mm), altura de estacas (cm) e comprimento do ramo secundário (cm); ao final do experimento, massa fresca da parte aérea e massas secas de raiz e parte aérea (g), sendo que para as variáveis mensuradas, semanalmente, foram calculados os respectivos incrementos percentuais semanais. Segundo os resultados do presente trabalho, no cultivo da pitaya, é necessário o uso de cobertura contra a incidência direta dos raios solares, onde as estruturas com 50% ou 75% de luminosidade podem ser usadas. O fornecimento de 20 L cova-1 de esterco bovino pode ser adotado como quantitativo no preparo de covas de pitaya, nas condições de clima e solo de Bom Jesus-PI.

Karyotypes of the blind catfish Pimelodella kronei from three different caves in the southwestern part of the State of São Paulo, Brazil, and of its presumed ancestor Pimelodella transitoria were examined. Chromosome number and formula, as well as C-banding pattern and NOR location were found to be the same in both species, supporting the hypothesis of a close relationship and even conspecificity of P. kronei and P. transitoria.

The paper aims at increasing the knowledge on the ecology of Polistes canadensis canadensis colonies in a Caatinga region. We studied some aspects of P.c. canadensis nesting habitats and colonial productivity. In the environmental conditions studied, this species nests on several types of substrata, particulary on thorny plants and in caves. The colony productivity and the cell reoccupation rate varies from one colony to another. In some colonies, we found cells with one, two and, more rarely, three reoccupations, this is upto four individuals produced in one cell only. The rate of the first reoccupation was 2.88-34.78%, with na average rate of 15.96%. The number of adults produced by the colonies of Flc, canadensis varied from 10 to 576 individuals. Productivity, given by the relationship between the number of born adults and the number of cell existing in the nest, varied from 31.25 to 123.19% and presented an average of 88.50%.

The tourist use of Santana cave provides a row of environmental damages, compromising partially the pristine conditions. Among the measures adopted to avoid this situation, this issue presents a contribution for the physical limits to tourist visitation and the indications for speleotouristic management. It was used the Cifuentes Carrying Capacity method and some basic principles of Visitors Impact Management Framework - VIM. The results show a Real Carrying Capacity (CCR) about 120 visits daily on the cave. The discussions raise a few hypotheses about the alteration in the method used and the temporal frequency between visitors groups, suggesting a provisional CCR of 117 and 135 visitors daily, respectively, during the week and in the weekends and holidays. The conclusions appoint the necessity of a conceptual revision in the Carrying Capacity methods, mainly about its adaptation for tourist management in caves. In the case studied, it is suggested the immediate beginning of environmental monitoring of the cave, to verify the plausibility from proposed visitation limits and the possible contributions for to mitigate the environmental impacts from speleotourism.

The Historical Jaraguá Gold Caves are vestiges of excavations in weathered rock, dating back to the Brazilian colonial times, situated NW of Jaraguá peak, in the São Paulo municipality (SP). The areas were investigated to support historical preservation innitiatives. The excavations have lateral steep slopes and a narrow fat bottom zone, occupied by dense vegetation. The trace of the excavations is sinuous, trending N40-50W, in accordance to a transition zone of Neoproterozoic rocks: metapelites and metapsamites by the SW side and calc-silicate rocks and amphybolites at NE. The structural control results from three successive deformation phases. Urban expansion and road construction, during the last 30 years, have strongly impacted the areas: (I) Base of Quebra-Pé hill; (II) Jardim Britânia; (III) Morro Doce; (IV) Nova Anhangüera Park. A 5 th site was disfgured by earthworks. The Jardim Britânia area is partly discharacterized by earthflls; this however does not impede further protection actions. This framework allows to recommend authorities: (1) to permit immediate preservation of these areas; (2) to develop programs to build an integrated site for scientifc diffusion or an educational center for exhibition of rocks, ores and mineral samples; (3) to support the interest of some owners to preserve the area called Morro Doce, (4) to put forward a few proposals for educational use of the excavations, by production of feld guides on the historic sites. The alternatives will help keeping alive the memory of mining in the São Paulo State.

Bats are hosts of a rich diversity of microorganisms. Many studies indicate a close link between bats and fungi with pathogenic potential, especially for living in environments such as caves, caverns and hollow trees, favorable to the maintenance and spread of fungi. The objective was to study the gastrointestinal mycoflora of bats. Of the 98 samples belonging to 11 species of bats coming from 15 studied cities, 20% of the species were Carollia perspicillata, 19% Artibeus lituratus, 17% Molossus rufus, 13% Glossophaga soricina, 9% Nyctinomops macrotis, 8% Molossus molossus, 7% Desmodus rotundus, 2% Lasiurus ega and 1% Eptesicus furinalis, Myotis nigricans and Tadarida brasiliensis. The genus Aspergillus sp. was isolated from 29% of the samples, followed by 6% Microsporum sp. and Penicillium sp. 4% Trichophyton sp. and zygomycetes and 2% Fusarium sp. Of yeast species, 14% were from Rhodotorula sp., 10% Candida sp. and 2% Cryptococcus sp., 22% of isolates remained unidentified. All 82 cultures of organs were negative for Histoplasma capsulatum. There was a statistically significant association between the results of microbiological culture and bat species (p < 0.05). We conclude that the bats can act as disperser agents of fungi with pathogenic potential, although other studies should be performed to establish strategies to identify the main factors correlated with the growth and spread of microorganisms in nature and implication of bats in the epidemiological cycle.
