Informação fluida e conhecimento no ciberespaço : uma análise do Portal Infonet-SE

The internet is a transbordering and potentializing environment for the information, since it makes possible the sheering, distribution and interaction of the contents available in it. However, this information system may generate an opposing move when it produces an avalanche of superficial information which difficult the absorption criticism by the user. This modern-liquid society, which is characterized by short living fashionisms, creates a fluid subject on which its habits do not become concrete, since they are so temporary that they don t shape up. The information also reproduces the same scenario, since the user is inserted into a logic based on supplying information and so it is conditioned to consume, not absorb or transform them into knowledge, since the flow of content production does not allow it. It is in his context that the publishing of cultural expressions come to be questioned, since they follow a liquid society trend. This discussion will take on topics that approach diverse cultural expressions in Sergipe, such as cinema, theater, craftsmanship, events, memory spaces(museums, art galleries, memorials, files, libraries, history institutes, science academies), amongst others and will analyze the content production of the Infonet Portal, from the reports published during April, May and June of 2008, period considered to be of cultural turbulence in the state, due to the June Festivals (Saint john, Saint Joseph and Saint Peter). To do so, Zigmunt Bauman s, Pierre Levy s, Edgar Morin s and Dominique Wolton s ideas were discussed. Besides, were analyzed the characteristics of the internet and its applicability within the portal hereby discussed in order to perceive the way the information is produced in the cyber culture, a movement that allows memorization, potentialization, interaction , besides other criteria inherent to the cyberspace

Estrutura genética de Chromis multilineata (Guichenot, 1853) (Perciformes Pomacentridae) na costa NE do Brasil e ilhas oceânicas: evidências de um passado evolutivo instável.

The fauna of Brazilian reef fishes comprises approximately 320 species distributed along the coast of the mainland and islands ocean. Little is known about the levels of connectivity between their populations, but has been given the interest in the relations between the offshore and the islands of the Brazil, in a biogeographical perspective. The oceanic islands Brazilian hosting a considerable number of endemic species, which are locally abundant, and divide a substantial portion of its reef fish fauna with the Western Atlantic. Among the richest families of reef fish in species are Pomacentridae. This study analyzed through analysis of sequences of the mitochondrial DNA control region (D-loop), the standards-breeding population of C. Multilineata in different areas of the NE coast of Brazil, involving both oceanic islands (Fernando de Noronha Archipelago and of St. Peter and St. Paul) and continental shelf (RN and BA). To this aim, partial sequences were used in the region HVR1 of mtDNA (312pb). The population structure and parameters for the estimates of genetic variability, molecular variance (AMOVA), estimation of the index for fixing (FST) and number of migrants were determined. The phylogenetic relationships between the populations were estimated using neighbor-joining (NJ) method. A group of Bayesian analysis was used to verify population structure, according to haplotype frequency of each individual. The genetic variability of populations was extremely high. The populations sampled show moderate genetic structure, with a higher degree of genetic divergence being observed for the sample of the Archipelago of St. Peter and St. Paul. At smaller geographical scale, the sample of Rio Grande do Norte and the Archipelago of Fernando de Noronha do not have genetic differentiation. Three moderately differentiated population groups were identified: a population group (I), formed by the Rio Grande do Norte (I') and the archipelago of Fernando de Noronha (I''), and two other different groups formed by the island population of the archipelago of Saint Peter and St. Paul (II) and Bahia (III). The genetic patterns found suggest that the species has suffered a relatively recent radiation favoring the absence of shared haplotypes. C. multilineata seems to constitute a relatively homogenous population along the West Atlantic coast, with evidence of a moderate population genetic structure in relation to the Archipelago of St. Peter and St. Paul. These data supports the importance of the dispersal larvae by marine current and the interpopulation similarity this species.

Levantamento cariotípico em espécies de peixes marinhos costeiros de fundo arenoso (Osteichthypes, Perciformes)

Cytogenetics analyses in fish are important because they compose a private group among the vertebrates, occupying a central position in the animal evolution. The Perciforms Order, dominant in the marine and freshwater environment, it constitutes a model potentially useful in the genetic evaluation of populations, as well as in the understanding of its evolutionary processes. In spite of this, cytogenetics studies in this great group is scarce, above all for the inhabitants of sandy bottom and pelagics habits. The present work proposed to contribute for the cytogenetic characterization of nine species of fish marine of sandy bottom of the coast of Rio Grande do Norte (Brazil), identifying the evolutionary patterns related to the karyotype in these species and the existence of filogenetics affinities between them and other Perciformes. The animals were collected in the beaches of the Redinha, Ponta Negra and Búzios (Coast of Rio Grande do Norte) and in Saint Peter and Saint Paul Archipelago. Later on they were submitted to the cytogenetics technical that consist of mitotic estimulation, obtaining of mitotics chromosomes, proceeded by techniques of conventional coloration (Giemsa) and chromosomic bands (Ag-RONs and C band). Diploid number and fundamental number equal to 48 were observed in most of the species: Menticirrhus americanus, Ophioscion punctatissimus, Pareques acuminatus (Sciaenidae); Chloroscombrus chrysurus (Carangidae); Echeneis sp. 2 (Echeneidae); Archosargus probatocephalus (Sparidae) and Orthopristis ruber (Haemulidae). Trachinotus goodei (NF=52) (Carangidae) and Echeneis sp. 1 (Echeneidae) (NF=54) presented variation in NF, staying constant a diploid number equal to 48. RONs was situated in pericentromeric position in whole the scianids, and in the species Echeneis sp. 2 (22° pair), O. ruber and A. probatocephalus (1° pair), coinciding with great heterocromatics blocks in M. americanus (1° pair), P. acuminatus (2° pairl) and O. ruber (1° pair). RONs was also located in the telomeric area of the short arm of the 5° and 11° acrocentrics pairs in T. goodei, 4° and 19° pairs of C. chrysurus, 1° pair (sm) of Echeneis sp. 1. The C band detected centromeric blocks in most of the chromosomes of the species of Sciaenidae, Carangidae and Echeneidae, with great blocks in A. probatocephalus (4° pair). Heterocromatic blocks in telomeric areas in submetacentrics of Echeneis sp. 1, and pericentromerics in M. americanus (1° and 8° pairs), O. punctatissimus (1° pair) and P. acuminatus (2° pair) were also observed. It is noticed a marked conservatism cromossomic in the species of the family Scianidae and Haemulidae in what says respect to the number of acrocentrics chromosomes and the location of RONs. Even so it is outstanding the presence of heterocromatinization events during the karyotypic evolution of this family. Already in the families Sparidae and Carangidae, the obtained results reaffirm examples of small variations structural resultants of inversion and translocation Robertsonian, as important mechanisms of diversification karyotipical, as well as a pattern numerical evolutionary conserved, also observed in representatives of Echeneidae of Atlantic in relation to Pacific. The presence of RONs multiple, observed in the species T. goodei and C. chrysurus seems to represent a character derived in the family Carangidae. The results for the species O. ruber and A. probatocephalus suggest the presence of possible geographical or climatic barriers among populations of NE of Brazil in relationship the one of the SE

Diversificação cariotípica em cinco espécies de moréias do Atlântico Ocidental (Anguilliformes)

The Anguiliformes is constituted by 15 families, 141 sorts and 737 species. In this group eight families possess at least one karyotyped species, where a prevalence of karyotypes with 2n=38 is evidenced chromosomes and high NF, apparently basal for the Anguiliformes. The only family who shows a different karyotypic pattern from the others is the Muraenidae family. In this, of the eight species already described, all of them present 2n=42 chromosomes. Despite the dimension of this Order, few species present karyotypics descriptions. In the present work, a species of Ophichthidae, Myrichthys ocellatus (2n=38, 8m+14sm+10st+6a, NF=70) and three species of Muraenidae, Enchelycore nigricans (2n=42, 6m+8sm+12st+16a, NF=68), Gymnothorax miliaris (2n=42, 14m+18sm+10st, NF=84), Gymnothorax vicinus (2n=42, 8m+6sm+28a, NF=56) and Muraena pavonina (2n=42, 6m+4sm+32a, NF=52), collected in the coast of the Rio Grande do Norte state, Saint Peter and Paul Rocks and in the coast of Bahia state were analyzed. Mitotics chromosomes had been gotten through mitotic stimulation with yeasts. Among the analyzed species, it is observed the presence of characteristic large metacentric chromosomic pairs (≅10µm). As for the structural standard, heterochromatics regions in these species in centromeric position of the majority of the chromosomic pairs and simple ribosomal sites had been evidenced. For the Ophichthidae family, the gotten data corroborate the hypothesis of karyotypic diversification mediated by the occurrence of pericentrics inversions and robertsonians rearrangements, while in the Muraenidae, the identification of larger chromosomic values (2n=42), suggests derived karyotypes, possibly caused by possible chromosomic fissions

As marcas culturais das festas populares no fotojornalismo dos periódicos Correio da Manhã e Tribuna do Norte

This research is about the cultural marks and meanings production on the popular culture context, in honor of Catholics Saints of June: Saint Antony; Saint John and Saint Peter (with celebrations in June 13th, 24th and 30th respectively). These marks are find on the newspapers’ photography of Tribuna do Norte (Natal, Rio Grande do Norte, Brazil) and Correio da Manhã (Lisbon, Portugal). All the photos were published in June 2012. The analysis has theory and methodology in Folkcommunication and in Sociocultural Photocatography. The investigation has focus in the meanings of these marks on the photojournalism about the popular parties and their practices. The study observes also a common view to report about popular culture, which has the influence of a hegemonic paradigm that considers itself the only true one.

Intercompreensão de línguas românicas: uma proposta para a leitura literária plurilíngue no ensino fundamental

The developed research aimed to investigate how students behave on elementary school in a plurilingual context, based on Intercomprehension of Romanic Languages with literary texts in the classroom. The theoretical framework prioritizes authors who consider reading literary text as an essential tool to the formation of reading and writing skills for students, such as: Amarilha (1997; 2003; 2007), Resende (1993), Kleiman, (1999), Villardi (1997), Aguiar (1991), Perrone-Moisés (2000), Lajolo (1993), Zilberman (1991), Cosson (2006), Andrade, Melo-Pfeifer, Santos, (2009), Sá; De Carlo; Antoine (2011), Alas Martins (2014), Doyé (2005), Souza, (2013), and others, according to the intercomprehension approach and plurilingualism. We use questionnaires as a methodological resources for this research, and we applied some activities that was developed based on intercomprehension from literary texts which represent three types of Romanic languages (Spanish, French and Italian), in addition to the participant observation in classes with students of the 8th grade from an elementary public school in the city of Natal (RN). The students could read and (inter) understand some texts of classic literature in those Latin languages and also in Portuguese, whose titles include “D. Quixote de la mancha” by Miguel de Cervantes; “O pequeno príncipe” by Antoine de Saint-Exupéry; and “Pinóquio” by Carlo Collodi. The data analysis shows that students understood the lessons with plurilingual texts as something which goes beyond the structure of language teaching, awakening themselves to the knowledge of new languages and cultures, and linguistic diversity as motivation at the time of understanding and literature as transforming element to Citizen formation of students.

O exame neurológico do recém-nascido pré-termo não complicado: avaliação pela escala de saint-anne dargassies, e screening pelas escalas de amiel-barrier-shnider modificada e prechtl ao termo

This study compared the evolution of posture, tone and neonatal reflexes in preterm infants without clinical or neurological complications before and after the age of term using the scale of Saint-Anne Dargassies. To reach the age of the term, was applied Scales Amiel-Barrier-Shnider changed and the Prechtl, traditionally used in the evaluation of term newborns, looking for possible changes to the term, while also evaluating the sensitivity of these scales. We studied 20 non-complicated preterm infants, both sexes aged 32-36 weeks, born in Januário Cicco Maternity School, from August 2006 to August 2007. Was applied to the scale of Saint-Anne Dargassies every two weeks until reach the term, and the range of Amiel-Barrier-Shnider changed and the Prechtl, after reaching 39 and 41 weeks. The evaluation result of articular angles was subjected to the test of Friedman ANOVA, significant differences between the three measurements of the scale of Saint-Anne Dargassies only for angles heel-to-ear to term. Neonatal reflexes changed in the period of prematurity were the cardinal points reflexes, Moro reflexes, cross extensions reflex and the automatic walking reflexes. The posture was the parameter which remained unchanged in the three scales. Considering a significance level of 5% by applying Cochran Q Test, it was found that the scale of Saint-Anne Dargassies is more sensitive to detect suspects. With this methodology and the results it was possible to prepare a manuscript: The neurological examination of non-complicated preterm newborns using the Sanit-Anne Dargssies Scale from birth to term: normal or altered? In which we describe that despite the good clinical condition, the RNP show changes in tone and neonatal reflexes. These data are important because though non-complicated RNP need further attention its maturation process, enabling us to detect and intervene early. With these results we can build a scale simplified neurological assessment made with items found most altered during the application of three scales. The development of this project has a multidisciplinary approach, because it involved Paediatric Neurologist, Physiotherapist and Neonatologist, as recommended by PPGCSA
