Data compilation on the biological response to ocean acidification: environmental and experimental context of data sets and related literature

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

THE SLOAN NEARBY CLUSTER WEAK LENSING SURVEY

We describe and present initial results of a weak lensing survey of nearby (z less than or similar to 0.1) galaxy clusters in the Sloan Digital Sky Survey (SDSS). In this first study, galaxy clusters are selected from the SDSS spectroscopic galaxy cluster catalogs of Miller et al. and Berlind et al. We report a total of seven individual low-redshift cluster weak lensing measurements that include A2048, A1767, A2244, A1066, A2199, and two clusters specifically identified with the C4 algorithm. Our program of weak lensing of nearby galaxy clusters in the SDSS will eventually reach similar to 200 clusters, making it the largest weak lensing survey of individual galaxy clusters to date.

The Ideal Timing for Experimental Cleft Lip Creation

Cleft lip and palate (CLP) is the most common congenital defect of the face. Many animal models have been utilized to study embryogenesis and pathogenesis of CLP, including the development of secondary anomalies and consequent deformities. However, the ideal gestational age for surgical creation of lip or palate defects in rat models has never been determined. The aim of the present study is to improve the experimental model utilizing rat fetuses, defining the most appropriate timing for creation of the lip defect model. The study was composed of three groups of fetuses undergoing surgical creation of a lip defect at the left side of the superior lip at 17.5, 18.5, and 19.5 days of gestation. Fetuses were harvested at 21.5 days of gestation (term = 22 days) and underwent macroscopic and microscopic analyses. We found that the most appropriate moment for lip defect creation was at 19.5 days, given the presence of lip depression at the site of the defect and asymmetry and retraction associated with interruption of the lip and complete reepithelialization of the borders of the defect.

Profundidade de semeadura e superação de dormência no crescimento inicial de sementes de Brachiaria dictyoneura (Fig. & De Not.) Stapf (1919) cv. Llanero

O Brasil é o maior produtor, consumidor e exportador de sementes de espécies forrageiras de clima tropical. Objetivou-se, com este estudo, avaliar o desenvolvimento inicial de Brachiaria dictyoneura cv. Llanero, em função da profundidade de semeadura e dos métodos de superação de dormência. O trabalho foi realizado em casa de vegetação, em blocos casualizados, com quatro repetições e em esquema de parcela subdividida. Os tratamentos aplicados às parcelas foram cinco, com as profundidades de semeadura de 0,0; 2,0; 4,0; 6,0 e 8,0 cm e, nas subparcelas, os métodos de superação da dormência com e sem escarificação. Cada parcela experimental foi constituída de 25 sementes. A partir do 10º dia de semeadura iniciou-se a contagem de plantas emergidas, a fim de se determinar o índice de velocidade de emergência e, aos 35 dias posteriores à semeadura, avaliou-se a emergência das plântulas, a altura de plantas e a matéria seca da parte aérea. As sementes de B. dictioneura semeadas em torno de 4,0 cm de profundidade e submetidas à escarificação mecânica apresentaram melhor desenvolvimento em todos os parâmetros avaliados. A semeadura superficial e aquela em profundidades abaixo de 4,0 cm mostraram-se ineficientes para o desenvolvimento inicial de B. dictioneura.

Um exercício de desconstrução do conceito e da prática de segmentação de mercado inspirado em Woody Allen

O conceito de segmentação de mercado constitui-se em uma forte ferramenta freqüentemente utilizada na tomada de decisão nas organizações. Neste artigo, busca-se analisar elementos nem sempre privilegiados quando se trata a segmentação de mercado como discurso hegemônico. A crítica aqui apresentada inspira-se no filme Desconstruindo Harry, de Woody Allen, o que permitirá compreender o exercício de desconstrução do conceito e da prática da segmentação de mercado com base no gênero e na etnia. Essa proposta ampara-se sobre o postulado de Derrida (1999) de que qualquer conceito, palavra ou significado léxico é passível de desconstrução e na hipótese de que o conceito de segmentação de mercado e sua prática encerram significados não revelados, guardando em si um conjunto de atores e vozes marginalizados.

Os (in)sofismáveis caminhos do storytelling : Woody Allen e o documentário ficcionado

ABSTRACT: Between pure documentary and pure fiction there are, more and more, a reasonable number of cinematic alternatives that convey a dimension of non-reality. Between the pointedly factual discourse and the irrational belief in an entirely narrative world, there intervenes an informed conviction in a truthful but nonexistent universe, in which the formal enunciation sells an image of objectivity. In a path that leads us from the forms and contents of reflexive and performative documentaries, according to Bill Nichols, and ends up in fake documentary itself, we will have the opportunity to stress the filmic construction and its inherent narrative purpose, be it a fictional story or the creator himself as character (others would say subject) of the cinematic construct. In a boomerang kind of logic, the more the objects direct us to a referent, the more they restore us a creative/authorial reference and, along with it, the narrative idea that instills it. In Woody Allen’s case, this storytelling manifests itself in the fake documentary genre, which works as if it is the reality, only to better manifest the sole reality that interests the director: that of the metacinema, or the cinema as self-referencial reality. The practical examples will be derived from the following films: Take the Money and Run (1969) e Husbands and Wives (1992).
