Barreiras à entrada no Setor Siderúrgico Brasileiro no período de 1993 a 2012

This study aims to identify and analyze the barriers to entry in the two technological routes (integrated and semi - integrated mills) , the Brazilian steel industry , specifically in the areas of Plans and Long , in the period 1993-2012 . Thus, the study is characterized as an exploratory - descriptive research, based on data collection from secondary sources. The competitiveness is influenced by structural market factor, among them the threat of new market entrants. The entrants can have their ticket inhibited by entry barriers. In the steel industry, it was identified that the main strong structural barriers are economic, the type of scale economy, highlighting the idle capacity, and sunk costs. Institutional and economic barriers, the diversification and product differentiation type, are considered moderate barriers. Economic barriers, the type absolute cost advantage and initial capital requirements, and strategic price barrier are considered weak. With this, one can consider that the input type which most closely approximates the market for national steel industries is blocked, since their main barriers are the structural type

Os sentidos sobre o professor e sua formação em 15 anos de Zetetiké: 1993 - 2007

This research presents a study on mathematics teacher education, examining the bibliographic production in 15 years of the journal Zetetiké (1993-2007), totalizing 140 papers. From these, 49 were classified as ‘teacher formation’, thus constituting the corpus of the investigation. The research focused on three units of recording and analysis: (i) problems of research; (ii) the meanings of ‘being a teacher’ and their ‘duties’; and (iii) the meanings of ‘teacher’s education’. For the processes of categorization we use Textual Analysis, which allowed us to observe some trends. Regarding the problems of research we found that the research actions involve a range from: to report, disclose, describe, identify up to study, discuss, understand, evaluate. With reference to ‘being teacher’ and its ‘duties’ in the whole period of this study it were pointed problems related to the mathematical content and to the pedagogical project of the school unit, with 30 papers giving prescriptions for the teachers actions in its educational context. With regard to the meanings on teacher education, the most frequent references concern: the functions of teacher formation; what is expected of the teacher during and after the education processes; and the emphasis on the importance of initial formation for mathematics teacher’s education.

Harbor Porpoise (Phocoena phocoena) Abundance in Alaska: Bristol Bay to Southeast Alaska, 1991-1993

Between 1991 and 1993, Alaska harbor porpoise (Phocoena phocoena) abundance was investigated during aerial surveys throughout much of the coastal and offshore waters from Bristol Bay in the eastern Bering Sea to Dixon Entrance in Southeast Alaska. Line-transect methodology was used, and only those observations made during optimal conditions were analyzed. Survey data indicated densities of 4.48 groups/100 km2, or approximately 3,531 harbor porpoises (95% C.I. 2,206-5,651) in Bristol Bay and 0.54 groups/100 km2, or 136 harbor porpoises (95% C.I. 11-1,645) for Cook Inlet. Efforts off Kodiak Island resulted in densities of 1.85 groups/100 km2, or an abundance estimate of 740 (95% C.I. 259-2,115). Surveys off the south side of the Alaska Peninsula found densities of 2.03 groups/100 km2 and an abundance estimate of 551 (95% C.I. 423-719). Surveys of offshore waters from Prince William Sound to Dixon Entrance yielded densities of 4.02 groups/100 km’ and an abundance estimate of 3,982 (95% C.I. 2,567-6,177). Combining all years and areas yielded an uncorrected density estimate of 3.82 porpoises per 100 km2, resulting in an abundance estimate of 8,940 porpoises (CV = 13.8%) with a 95% confidence interval of 6,746-11,848. Using correction factors from other studies to adjust for animals missed by observers, the total number of Alaska harbor porpoises is probably three times this number.

THE INFLUENCE OF THE 1992-1993 EL NINO ON THE REPRODUCTIVE BIOLOGY OF Scomber japonicus peruanus (JORDAN & HUBB, 1925)

The influence of the 1992-1993 El Nino events on the reproductive behavior of the Scomber japonicus peruanus (Chub mackerel) was studied from samples collected monthly, along the Peruvian coast (3 degrees 23`S-14 degrees 00`S), from January 1990 to December 1993. The monthly variation of the gonadosomatic index and the frequency of the periods of gonad maturation evidenced that the spawning of the species occurred all year long, being more intense in summer. The values of the gonadosomatic index were higher during the occurrence of the 1992-1993 El Nino, while the body weight and gonad weight decreased. Regarding the condition factor, its values decreased in females over 35 cm in fork length.

Teses e dissertações sobre gênero e desempenho escolar no Brasil (1993 - 2007): um estado da arte

Resultado de levantamento exaustivo - que localizou 71 estudos - das teses e das dissertações produzidas no Brasil, entre 1993 e 2007, sobre as diferenças de desempenho escolar entre os sexos, este artigo enfoca 21 trabalhos cujos achados nos pareceram mais relevantes. São pesquisas predominantemente qualitativas e que abordam, principalmente, as séries iniciais do Ensino Fundamental de escolas públicas em diferentes regiões do País, tanto em áreas urbanas como rurais. Permitem afirmar alguma homogeneidade na cultura escolar, em especial nessas séries, no que tange às opiniões das professoras, reafirmando diferenças de comportamento entre meninos e meninas e atribuindo essas diferenças à socialização familiar. São escassas as pesquisas que incorporam as falas das crianças e escassos os estudos sobre as camadas médias. Do ponto de vista teórico, poucas pesquisas articulam o gênero a outros determinantes sociais e raras demonstram uma apreensão complexa das relações de gênero no campo simbólico, para além da interação homem- mulher.
