As orações subordinadas não classificadas pela NGB agente da passiva modal - locativa

As orações subordinadas agente da passiva, as orações modais e as locativas têm pleno funcionamento na língua portuguesa, embora não tenham seu reconhecimento na Nomenclatura Gramatical Brasileira, o que significa dizer que estas orações não existem, oficialmente, na nossa língua. Este trabalho tem por objetivo demonstrar como este tema é desenvolvido entre os autores de língua portuguesa, entre gramáticos tradicionais, funcionalistas e pedagógicos e sintaticistas e, principalmente, que estas orações são normalmente utilizadas, tanto na língua falada como na escrita. Realizou-se um estudo comparado entre 21 renomados autores de língua portuguesa, em uma detalhada revisão de literatura. Destarte contribui-se para ampliação da pesquisa na área da sintaxe portuguesa a fim de promover uma reflexão aprofundada sobre o tema entre os estudiosos da língua portuguesa ou entre os que, de alguma forma, se interessam pelo nosso idioma. Mas o que importa mesmo como resultado da pesquisa é comprovar o pleno funcionamento destas orações no idioma em movimento, na língua viva. Para tal, compôs-se um pequeno corpus por meio de textos midiáticos. Foram selecionados sessenta recortes dos jornais O Globo, JB e das revistas Veja e CartaCapital, todos on line, que comprovam o uso natural, ou mesmo comum, das orações agente da passiva, das orações modais e locativas. Assim tornou-se possível afirmar que estas orações funcionam plenamente em nosso idioma, encontram, na sintaxe portuguesa, seu habitat natural e ganham vida, graça e força na fala e na escrita dos falantes de língua portuguesa, na nossa fala e na nossa escrita, de nós, brasileiros

Effect of towing speed on retention of zooplankton in bongo nets

Long-term time series of zooplankton data provide invaluable information about the fluctuations of species abundance and the stability of marine community structure. These data have demonstrated that environmental variability have a profound effect on zooplankton communities across the Atlantic basin (Beaugrand et al., 2002; Frank et al., 2005; Pershing et al., 2005). The value of these time series increases as they lengthen, but so does the likelihood of changes in sampling or processing methods. Sam-pling zooplankton with nylon nets is highly selective and biased because of mesh selectivity, net avoidance, and damage to fragile organisms. One sampling parameter that must be standardized and closely monitored is the speed of the net through the water column. Tow speed should be as fast as possible to minimize net avoid-ance by the organisms, but not so fast as to damage soft bodied zooplankters or extrude them through the mesh (Tranter et al., 1968; Anderson and Warren, 1991).

CHARACTERIZATION OF PHOTOCONDUCTIVE SEMICONDUCTOR SWITCHES UNDER NONLINEAR MODE CONDITION

A photoconductive semiconductor switch (PCSS) would work in a nonlinear mode under high biased electrical field. The experimental results of nonlinear critical state have shown that both the biased voltage and the laser energy may have working thresholds to turn on the nonlinear modes. The relation between the biased voltage (aid the laser energy is inverse ratio, i.e., higher biased field need lower laser energy for nonlinear mode, and vise versa. At the nonlinear critical point, the output of PCSS is unstable, as both the linear and nonlinear pulse may occur. As the laser energy and biased field increase, the PCSS would work in the nonlinear mode steadily. (C) 2008 Wiley Periodicals, Inc.

中国特有针叶树种对气候变化的敏感性研究

About 214 trees in 9 sampling sites, representing 5 endemic conifer species, were collected from the western Sichuan Province and eastern Qinghai Province, China. In this study, structure we try to investigate tree-ring sensitivity to climate in order to obtain primary information of reconstructing past climate from the trees in this region. All the 5 species present distinct ring boundaries ^ few ABS(absent rings) and available for cross-dating,which are all past the test by program COFECHA. Statistics for all the 8 tree-ring width residual chronologies present significant inter-correlation between series and high values of mean sensitivity. As well as the maximum latewood density of Picea crassifolia Kom and Pinus densata Mast. These results indicate usefulness of these chronologies for dendrochronological studies. Pearson correlation analyses were applied to provide a basic estimate of the causal relationships between tree-ring width and climate factors. We found some significant relationships between tree-ring width> maximum density and temperature as well as precipitation. Especially, there is high correlation between the maximum density of the Picea crassifolia Kom and the index of moisture, the ratio of precipitation and temperature, which can indicate well the climate; however the higher correlation can be see between the maximum density of Pinus densata Mast and the total temperature from June to September. Regardless of tree species, chronologies in our study region presented accordant variations of which may reveal strong common climate signal. Thus these chronologies are shown to be dependable for building tree-ring network in the nearly future. However, there are limitations in this study, only monthly mean of temperature and precipitation were available. Also, for this typical subtropical mountain system, meteorological stations are usually located in valley and biased to represent moisture conditions on the slopes. Thus the estimation of precipitation both in temporal and spatial domain was rather restricted. Further study, such as wood anatomy, physiology and densitometry, are needed for better understanding the environmental and climatic history in this area.

Kuailous ou Po tau ya : imagens no feminino sobre os portugueses em Macau

Tendo Macau por contexto, quinze anos após a transferência da sua administração para a República Popular da China e cinco séculos de presença portuguesa, o estudo efetua uma abordagem às representações e estereótipos sociais dos portugueses, a partir de um inquérito a cento e setenta e cinco mulheres chinesas desta Região Administrativa Especial (RAEM). Tendo como marcos conceptuais a Teoria das Representações Sociais, de Moscovici, e a Teoria da Identidade Social, de Tajfel, o estudo procura explicitar os saberes sociais construídos por esse grupo de referência, determinantes na forma como se processa a comunicação e a interação grupal com portugueses e âncora para a construção de estereótipos com os quais esses processos são simplificados, mas também enviesados. Antevendo-se, num horizonte não muito longínquo, decisões quanto à manutenção do princípio “um país, dois sistemas”, que viabiliza a preservação de marcas portuguesas (como a língua) e uma abertura especial à presença de portugueses em Macau, a compreensão das imagens e metáforas sobre esta comunidade constitui estratégia relevante para a perspetivação, no presente como no futuro, das relações intergrupais que a envolvem. O estudo conclui que as representações sobre os portugueses são, no essencial, de pendor positivo e exibem uma abertura à proximidade social e à participação desta comunidade nas dinâmicas sociais da RAEM. Mas assinala também áreas de potencial maior conflitualidade na defesa, pelo endogrupo, de áreas vitais de afirmação dessa nova ordem social pós- transferência.

Evaluación de la efectividad de una organización en el campo de percepción de marca usando un sistema de simulación computarizado basado en agentes

El presente proyecto de investigación tiene como objetivo general evaluar la efectividad de los esfuerzos de una unidad de negocio particular de la compañía Novartis de Colombia S.A. en el área de la percepción de marca mediante un sistema de simulación que implementa una metodología para la medición de esta última. Se tiene en cuenta que contar con datos exactos acerca de cómo los clientes finales perciben una marca es un tarea dispendiosa y que aún no tiene una fórmula matemática, por lo tanto, es muy subjetivo el proceso de entender a los consumidores por parte de los directivos de la empresa. El proceso planea que por medio del procedimiento planteado que se basa en una simulación por computador y más concretamente con una modelación basada en agentes se permita acercar a las partes involucradas en el proceso de compra, es decir, la empresa involucrada, vendedores, clientes y finalmente clientes potenciales.

Dual technological development in Botswana agriculture: A Stochastic input distance function approach

To improve the welfare of the rural poor and keep them in the countryside, the government of Botswana has been spending 40% of the value of agricultural GDP on agricultural support services. But can investment make smallholder agriculture prosperous in such adverse conditions? This paper derives an answer by applying a two-output six-input stochastic translog distance function, with inefficiency effects and biased technical change to panel data for the 18 districts and the commercial agricultural sector, from 1979 to 1996 This model demonstrates that herds are the most important input, followed by draft power. land and seeds. Multilateral indices for technical change, technical efficiency and total factor productivity (TFP) show that the technology level of the commercial agricultural sector is more than six times that of traditional agriculture and that the gap has been increasing, due to technological regression in traditional agriculture and modest progress in commercial agriculture. Since the levels of efficiency are similar, the same patient is repeated by the TFP indices. This result highlights the policy dilemma of the trade-off between efficiency and equity objectives.

Razzisti a parole (per tacer dei fatti)

Based on a wide bibliographic apparatus, and on a discourse-analysis approach, but written in a very accessible way to reach also a non-specialist audience, the pamphlet focuses on misleading and biased representations – through every-day stereotypes, media clichés, political speeches – of migration and migrants in today’s Italy, and is exciting a national debate about the strong relationship between language abuses, political and social misrepresentation, lack of citizenship for migrants and asylum seekers in Italy.

Prêt-à-Médiatiser by House of POLLYFIBRE

Prêt-à-Médiatiser by House of POLLYFIBRE is a performance/film that takes the fashion show catwalk as a site for exploration, with a focus on the dialogue between liveness and mediatisation. The performance showcases a clothing collection that has been designed to be documented and thus is challenged in the context of the live event. Motivated by the 2-dimensionality and biased perspective of mediated images such as magazine photography, social network profiles images and the surfaces of digital interfaces, the garments are one sided and obstruct the models in their attempt to play out familiar fashion poses, unless they align themselves 'correctly' for the lense. There is material metaphor and wordplay throughout, for example the clothing pieces are made from interfacing fabrics that are physically cut, pasted and layered to create the rigid flat silhouettes. The performance is accompanied by live sound created by tools of the fashion industry (including scissors and camera clicks) that have been adapted and amplified to be used as instruments. The audience and press are invited to document the live event and the subsequent film is made using footage collated from the crew, the audience and the official press

Control without deception

Lying to participants offers an experimenter the enticing prospect of making “others' behaviour” a controlled variable, but is eschewed by experimental economists because it may pollute the pool of subjects. This paper proposes and implements a new experimental design, the Conditional Information Lottery, which offers all the benefits of deception without actually deceiving anyone. The design should be suitable for most economics experiments, and works by a modification of an already standard device, the Random Lottery incentive system. The deceptive scenarios of designs which use deceit are replaced with fictitious scenarios, each of which, from a subject's viewpoint, has a chance of being true. The design is implemented in a sequential play public good experiment prompted by Weimann's (1994) result, from a deceptive design, that subjects are more sensitive to freeriding than cooperation on the part of others. The experiment provides similar results to Weimann's, in that subjects are at least as cooperative when uninformed about others' behaviour as they are if reacting to high contributions. No deception is used and the data cohere well both internally and with other public goods experiments. In addition, simultaneous play is found to be more efficient than sequential play, and subjects contribute less at the end of a sequence than at the start. The results suggest pronounced elements of overconfidence, egoism and (biased) reciprocity in behaviour, which may explain decay in contributions in repeated play designs. The experiment shows there is a workable alternative to deception.

Mapping the knowledge covered by library classification systems

This study explores, in 3 steps, how the 3 main library classification systems, the Library of Congress Classification, the Dewey Decimal Classification, and the Universal Decimal Classification, cover human knowledge. First, we mapped the knowledge covered by the 3 systems. We used the 10 Pillars of Knowledge: Map of Human Knowledge, which comprises 10 pillars, as an evaluative model. We mapped all the subject-based classes and subclasses that are part of the first 2 levels of the 3 hierarchical structures. Then, we zoomed into each of the 10 pillars and analyzed how the three systems cover the 10 knowledge domains. Finally, we focused on the 3 library systems. Based on the way each one of them covers the 10 knowledge domains, it is evident that they failed to adequately and systematically present contemporary human knowledge. They are unsystematic and biased, and, at the top 2 levels of the hierarchical structures, they are incomplete.

Hydrophilization of PVC surfaces by argon plasma immersion ion implantation

Commercial polyvinylchloride (PVC) sheets were treated by plasma immersion ion implantation, PIII. Samples were immersed in argon glow discharges and biased with 25 kV negative pulses. Exposure time to the bombardment plasma changed from 900 to 10,800 s. Through contact angle measurements, the effect of the exposure time on the PVC wettability was investigated. Independent of t, all samples presented contact angles, theta, equal to zero after the treatment. However, in some cases, surface hydrophilization was not stable, as revealed by the temporal evolution of theta. Samples bombarded for shorter periods recovered partially or totally the hydrophobic character while the one exposed for the longest time stayed highly hydrophilic. These modifications are ascribed to the Cl loss and O incorporation as shown by XPS measurements. Furthermore, the mobility of surface polar groups and the variation in the cross-linking degree can also affect the PVC wettability.
