This work aims to investigate the institutionalization of management processes in the legislation of the Brazilian education. For this study was considered the first decades of the twentieth century (1911-1950). The laws of Brazil in the early Republic were derived from tradition or forged by the great legislators. In turn, the tradition is inserted in the power of social organization that is preserved, in a more forceful manner, through the norms and rules. With this assumption, the study chose the Rivadávia and Carlos Maximiliano Reforms, both of the beginning of the century, and the Organic Laws of Teaching, granted by the government in this period, to understand how legislation institutionalized the role of the director in basic education in this context history. The reflections presented introduce historical elements that demonstrate actions and relationships that remain in the form of habits in the school managements. These institutionalized elements contribute to the debate about the political and pedagogical difficulties pointed out by scholars and professionals, related to the promotion of democratic management in the public school.

Loxandrus oophagus sp. nov. is described (type-locality: Uberlandia, State of Minas Gerais, Brazil). Larvae, pupae and adults of the new species of the carabid beetle were collected on foam nests of the anuran Leptodactylus fuscus (Schneider, 1799) in the surroundings of Uberlandia, 18 degrees 55S, 48 degrees 17W (Brazil, Minas Gerais), at 750 m altitude. The new species is compared with the similar Loxandrus quinarius Will & Liebherr, 1997, only known from Santa Cruz, Bolivia, differing by the morphology of tarsomeres. Larvae prey on anuran eggs. Description of the immatures and the natural history of the species are provided. The larva differs from the known larvae of Loxandrus species mainly by being eruciform, glabrous and depigmented, its small head and legs, and the lack of stemmata and urogomphi, representing an unusual last instar type among the Carabidae.

The time to reach the maximum response of arterial pressure, heart rate and vascular resistance (hindquarter and mesenteric) was measured in conscious male spontaneously hypertensive (SHR) and normotensive control rats (NCR; Wistar; 18-22 weeks) subjected to electrical stimulation of the aortic depressor nerve (ADN) under thiopental anesthesia. The parameters of stimulation were 1 mA intensity and 2 ms pulse length applied for 5 s, using frequencies of 10, 30, and 90 Hz. The time to reach the hemodynamic responses at different frequencies of ADN stimulation was similar for SHR (N = 15) and NCR (N = 14); hypotension = NCR (4194 +/- 336 to 3695 +/- 463 ms) vs SHR ( 3475 +/- 354 to 4494 +/- 300 ms); bradycardia = NCR (1618 +/- 152 to 1358 +/- 185 ms) vs SHR (1911 +/- 323 to 1852 +/- 431 ms), and the fall in hindquarter vascular resistance = NCR (6054 +/- 486 to 6550 +/- 847 ms) vs SHR (4849 +/- 918 to 4926 +/- 646 ms); mesenteric = NCR (5574 +/- 790 to 5752 +/- 539 ms) vs SHR (5638 +/- 648 to 6777 +/- 624 ms). In addition, ADN stimulation produced baroreflex responses characterized by a faster cardiac effect followed by a vascular effect, which together contributed to the decrease in arterial pressure. Therefore, the results indicate that there is no alteration in the conduction of the electrical impulse after the site of baroreceptor mechanical transduction in the baroreflex pathway (central and/or efferent) in conscious SHR compared to NCR.

The aim of this study was to describe and illustrate the morphology of the spermatozoon of the Western Atlantic shrimp, Hippolyte obliquimanus. Individuals were sampled from Itagua Beach (Ubatuba, southern Brazil). The male reproductive system was dissected and morphological analysis was undertaken using a stereomicroscope, a light microscope, and transmission electron and scanning electron microscopes. When viewed from the nuclear or acrosomal poles, each spermatozoon has many translucent radiating arms (about 20) from a denser cell body, while laterally the cell body and arms resemble a "cnidarian medusa", with all the arms projecting away from the bell-like cell body. This sperm morphology is distinct from the "thumbtack"-shaped spermatozoa observed in the majority of carideans but has similarities to the spermatozoa of Rhynchocinetes spp. The morphology of sperm of several species of the genus Hippolyte resembles the spermatozoon of H. obliquimanus with the presence of posterior nuclear arms, but it is necessary to study other Hippolyte species to place these arms in the context of the genus.

Biological aspects of sailfin dory, Zenopsis conchifer, were studied from 839 individuals obtained from deep-sea commercial bottom trawling off southern Brazil at depths up to 526 m in 2002 and 2003. Samples included fish from 101 mm Lt and 15 g up to 640 mm Lt and 2,9 g. The sex-ratio was 50% at 150 mm Lt and between 300-350 mm Lt, with females outnumbering males in the remaining size classes. Reproductive activity seems to peak between July and August ( austral winter). Size at attainment of 50% maturity (Lt(50)) was 311 mm Lt in females. The mean length and maturity of the specimens increased with depth, suggesting that larger fish concentrate in deeper waters.

Hippolyte obliquimanus is a marine shrimp reported from the Caribbean Sea and Brazil. The literature provides indications for morphological variation between populations from those regions and the species has a troubled taxonomic history. The aims of this study were to analyse morphological and genetic variation in the populations of H. obliquimanus from Brazil and the Caribbean Sea and to verify if those might support separation of H. obliquimanus into two or more species. This hypothesis was tested with the analysis of morphological and genetic data (mitochondrial gene 16S and the barcode region Cytochrome Oxidase I). The material analysed was obtained from samples and from loans of zoological collections. The rostrum as well as pereiopods 3, 4, and 5 were the adult morphological characters that showed variation, but this occurred in samples from both regions, Brazil and the Caribbean Sea. The sequences of the 16S gene were identical among all specimens analysed. There was, however, variation among the sequences of the barcoding gene COI (<2.0%); this divergence separated the specimens into two groups (Brazil versus the Caribbean) and these groups did not share haplotypes. In conclusion, specimens from the regions analysed showed both morphological and genetic variation, but these did not support the separation of H. obliquimanus into two or more species.

Anchoviella juruasanga is described from the drainages of rios Negro, Madeira, Tapajós, Trombetas, Tocantins, and Jari, in the Amazon basin, Brazil. The new species is distinguished from its congeners by having a short upper jaw, with its posterior tip extending between the verticals through anterior and posterior margins of the pupil (vs. posterior tip of upper jaw extending beyond the vertical through posterior margin of the pupil). Anchoviella juruasanga is also distinct from other strictly freshwater Amazonian species of the genus by the distance from tip of snout to posterior end of upper jaw between 8 and 11% in standard length (vs. 14% or more in A. alleni, A. carrikeri, A. guianensis, and A. jamesi). The anal-fin origin slightly posterior to or at the vertical through the base of the last dorsal-fin ray further distinguishes the new species from A. alleni (anal-fin origin posterior to the vertical through the last anal-fin ray by at least 14% of head length) and A. jamesi (anal-fin origin anterior to the vertical through the last anal-fin ray). An identification key for the Amazonian species of Anchoviella, including marine and estuarine species known to occur in the lower portion of the basin, is presented.

Questa ricerca mostra l’evoluzione della letteratura mitologica per ragazzi in Italia. Il primo libro italiano di mitologia per bambini è stato pubblicato nel 1911 (lo stesso anno di un’importante e violenta guerra coloniale tra l’Italia e la Libia): la scrittrice italiana Laura Orvieto pubblicò allora “Storie della storia del mondo”, in cui riunì antichi racconti greci per giovani lettori. Queste storie erano ispirate al libro mitologico per bambini “Il libro delle meraviglie” di Hawthorne (titolo originale “A Wonder Book for Girls and Boys”). In seguito molti scrittori italiani scrissero libri mitologici per giovani lettori: serie importanti di libri di mitologia per bambini furono pubblicate durante il regime mussoliniano – talvolta per diffondere l’ideologia fascista della superiorità romana. Durante questo periodo, i libri mitologici spesso mostravano uno stile letterario solenne. Dopo la seconda guerra mondiale, la letteratura mitologica per bambini cambiò lentamente prospettiva: gli scrittori italiani cominciarono ad usare il mito per parlare di problemi sociali (p.e. Gianni Rodari descriveva re Mida come un capitalista) e per spiegare le diverse condizioni umane (p.e. Beatrice Masini fa riferimento alle dee e alle eroine greche per descrivere la condizione femminile). La ricerca analizza anche la relazione tra mito e scuola in Italia: i racconti mitologici hanno sempre fatto parte dei programmi scolastici italiani per bambini dagli 8 agli 11 anni. Le riforme scolastiche – deliberate negli anni ’20 e ’40 – fissarono pratiche didattiche sui miti ancora oggi in uso. I racconti mitologici erano soprattutto un supporto per gli studi storici e letterari. Tuttavia, negli ultimi decenni, i miti sono divenuti un importante aiuto per gli insegnamenti scientifici e artistici.

Il lavoro di ricerca vuole analizzare, attraverso lo studio specifico della rivista artistico letteraria «L’Eroica» fondata a La Spezia nel 1911 da Ettore Cozzani e Franco Oliva, gli artisti e le situazioni in cui si sviluppa e si diffonde in Italia un linguaggio grafico di tipo fauve-espressionista, in perfetta sintonia con le coeve esperienze straniere. Nello specifico, si è focalizzata l’attenzione sui così detti ‘anni eroici de L’Eroica’ (1911-1917), periodo in cui risulta più evidente il passaggio che si ebbe nel panorama dell’illustrazione italiana da uno stile ancora riconducibile a un linguaggio simbolista a uno, per l’appunto espressionista. Questa rivista, infatti, nella fase conosciuta come “gli anni eroici dell’Eroica” (1911-17), s’interessa in modo quasi esclusivo alla xilografia contemporanea avvalendosi in un primo momento della collaborazione di artisti noti nell’ambito del gusto liberty come, ad esempio, Adolfo De Carolis e dei suoi allievi (Gino Barbieri, Ettore di Giorgio, Antonio Moroni). Tale collaborazione però termina con la cosiddetta “Secessione degli Xilografi”, ossia l’abbandono nel 1914 da parte di De Carolis e dei suoi della testata spezzina, circostanza questa che determinerà un nuovo indirizzo stilistico per la rivista in cui prenderanno sempre più spazio artisti di una generazione più giovane, peraltro già attivi su «L’Eroica» stessa, quali ad esempio Lorenzo Viani, Arturo Martini, Emilio Mantelli, Felice Casorati, Giuseppe Biasi, Roberto Melli e Gino Carlo Sensani, questi ultimi tutti rappresentanti di un espressionismo italiano di primo ordine
