Would Chrysomya albiceps (Diptera: Calliphoridae) be a beneficial species?
Madeira, N.G.;
Arquivo Brasileiro de Medicina Veterinária e Zootecnia , 2001, DOI: 10.1590/S0102-09352001000200004
Abstract: chrysomya albiceps (widemann) develops on animal carcasses and may cause secondary myiases. an adult female merino sheep presented a lesion of roughly circular shape with a 7.5cm radius in the anterior part of the thorax. a large number of second-instar larvae was removed from the lesion in addition to first-instar larvae from the wool. a third-instar larva was also obtained from the same lesion site and in the laboratory gave origin to a cochliomyia hominivorax (coquerel) adult insect. the larvae retrieved from the lesion were nurtured in laboratory. pairs consisting of 100 individuals were formed with the adult specimens obtained from the larvae and kept in two cages. in all of the 800 adults reared in the laboratory and examined (100 per generation) the propisternal seta was absent in the spiracle on both sides, this trait was highly stable. the 200 larvae examined, 15 per generation, did not present spines in the column of the ventral process of the penultimate abdominal segment and the column of the ventral process was triangular and the apex of the column process presented numerous spines. these characteristics allowed identifying these specimens as c. albiceps. however, since c. albiceps has the ability to damage intact tissues, it may be causing relevant aggravation when associated with c. hominivorax and can not be considered innocuous.

Abstract: there is a growing yield in the literature on the main determinants of the competitiveness of small and medium enterprises. one important contribution in this way is the assumption that the clustering of firms can bring them strong benefits, also in terms of productive improvement. based on these assumptions, this paper aims to exam the main effects of the clustering firms on the manufacturing process upgrading of small firms, by the analysis of the dissemination of manufacturing practices and tools in local systems. to this end, a survey with 42 small footwear producers was carried out at the local system of franca, brazil. the study investigated the existence of manufacturing process improvement among these firms and the main sources of information for the dissemination of these tools. the main results show that the clustering firms can stimulate the adoption of new manufacturing management practices, through both deliberate channels of dissemination of new knowledge among firms and the spontaneous ways of information exchange, which are usual in these local production systems. in addition, it was possible to notice that the level of appropriability of these benefits depends on the existence of previous knowledge inside firms, that is, their absorption capacity.
A atua??o de ex-arenistas e ex-emedebistas na assembleia nacional constituinte
Madeira, Rafael Machado;
Revista Brasileira de Ciências Sociais , 2011, DOI: 10.1590/S0102-69092011000300015
Abstract: which was the behavior of the remaining representatives of arena and mdb in the national constituent assembley? to what extent the analysis of partisan affiliation history is a good variable to understand the decision making process in important plenary assembly voting? the study points out that beyond partisan affiliations, having been affiliated to arena or to mdb consists in a relevant variable to predict the choices of the great majority of former-arenistas and of former-emedebistas during the national constituent assembley, no matter their respective partisan affiliations at voting moments.
O abandono da consulta de enfermagem: uma análise compreensiva do fen?meno
Madeira, Anézia Moreira Faria;
Revista da Escola de Enfermagem da USP , 1996, DOI: 10.1590/S0080-62341996000100008
Abstract: the purpose of this study was to understand the abandonment of nursing onsultation focused on children 0 to 2 years old. a phenomenological approach was used to make apprehension of the essence of the phenomenon and to try to understand it without becoming attached to its determinant causes. interviews were done with 12 mothers to describe their experiences on nursing consultation and, therefore, making possible to see the essence of the phenomenon.
Phosphorus desorbability in soils with andic properties from the Azores, Portugal
Auxtero,E.; Madeira,M.;
Revista de Ciências Agrárias , 2009,
Abstract: desorbability of phosphorus (p des) at p sorption maxima in eighteen horizons (surface and subsurface) of soils with andic properties from the azores, portugal, was determined by eight successive extractions using distilled water (h2o), calcium chloride (cacl2), bray 2 (b2), mehlich 3 (m3), egnér-riehm (er) and olsen (ol) methods. the highest proportions of p des by the b2, m3, er and ol methods (29-100%) were obtained in soils with weak andic properties (vitrandic haplustepts, typic haplustepts and andic haplustepts), indicating that p can be easily lost from these soils to nearby water bodies, through surface runoff and subsurface drainage. in contrast, low proportions of p des (4-57%) by these methods were obtained in allophanerich (acrudoxic hydrudands and typic placudands) and non-allophanic soils (acrudoxic hydrudands and alic hapludands), indicating that large amounts of p can be sorbed in an unavailable form by these soils. of the six methods used, the proportions of p des obtained by h2o and cacl2 were consistently lower than those obtained by the b2, m3, er and ol methods. the proportion of p des obtained by the b2 method was highly correlated with other methods (m3, er and ol) suggesting that the b2 is also an effective method to extract p in most of the studied soils. the proportions of p des obtained by different methods were negatively correlated with feo and fed, correlatios being stronger than with alo, ald, alp and fep contents. this indicates that feo and fed plays an important role in desorbability of p in studied soils.

Abstract: language learning beliefs has been a frequently discussed topic of applied linguistics in the area of language learning and teaching. this paper discusses the beliefs learners and teachers of english as a second language hold about the learning/teaching process. i will start the discussion exposing the reason why more and more researchers are interested in investigating the beliefs system of those involved in the task of learning the english language to show the influence that the beliefs that compose this system have in the way they approach the process of learning a new language. i will next present and discuss some of the main factors that act in the construction of students and teachers′ beliefs and some of the beliefs they hold, not all of which beneficial for the good performance in that process.
A Itinerancia dos artistas: a constru??o do campo das artes visuais em Brasília (1958-1967)
Madeira, Angélica;
Tempo Social , 2002, DOI: 10.1590/S0103-20702002000200010
Abstract: this article presents the first results of a research which aims at mapping and analyzing the construction and the consolidation of the field of the visual arts in brasília. the whole project is divided into three significant moments of the city's history: the fifties, when the rationalist model in architecture and urban design, and concretism in the field of the arts became hegemonic; the late sixties, when conceptualism was strongly affirmed on the brazilian art scene; and finally, the two last decades, which brought big changes to patronage and to art market strategies. the article also punctuate some theoretical and methodological remarks.

Madeira, Felícia Reicher;
S?o Paulo em Perspectiva , 2004, DOI: 10.1590/S0102-88392004000200009
Abstract: this article presents a proposal of evaluation of the social public politics different from the conventional - that focuses on the results of the impacts -, proposing new conduct, closer to the social sciences and prioritizing the analyses of facts and defining processes of the creation and the development of the program that allows the evidence of formulation mistakes. thus, it evaluates the young citizen program: my first employment and suggests enlargement of comparative social research.
Extractability of aluminium and forms in solution of soils derived from granite in Portugal
Auxtero,Edgardo; Madeira,Manuel;
Revista de Ciências Agrárias , 2011,
Abstract: extractable aluminium (al) was determined in surface and subsurface horizons of eleven pedons derived from granite occurring in portugal, under a wide range of precipitation. five successive extractions with 1 m kcl, 0.5 m cucl2 and 0.33 m lacl3 were used. monomeric (alm) and organic (alorg) forms of al in the soil solution, extracted at field capacity, were also determined. amounts of extracted al were greatest with the 0.5 m cucl2 and lowest with the 1 m kcl. these amounts showed strong positive correlation with soil organic c contents. soil horizons having high contents (56-80 g kg-1) of organic c showed the highest amount of extractable al by the 0.5 m cucl2 (12.2-30.9 cmolc kg-1). organically bound al extracted by the 0.5 m cucl2 and 0.33 m lacl3 was also highest in these soils (7.6-10.1 and 4.7-8.3 cmolc kg-1, respectively). in contrast, lowest amounts of al extracted by the 1 m kcl, 0.5 m cucl2 and 0.33 m lacl3 (0.9-4.3, 4.1-17.1 and 2.2-7.2 cmolc kg-1, respectively) were observed in horizons containing low organic c content (3-22 g kg-1). concentrations of total (alt), monomeric (alm) and organic (alorg) al in the soil solution of studied soils also increased with increasing soil organic c content, but only alm was significantly correlated with soil organic ccontent. solution of soils having low organic c contents (3-6 g kg-1) showed the lowest concentrations of alt, alm and alorg (0.09-1.60, 0.06-0.38 and 0.03-1.29 μg ml-1, respectively). in contrast, the concentrations of alt (7.1-17.2 μg ml-1),alm (0.8-0.9 μg ml-1),and alorg (7.6-16.9 μg ml-1)were much higher in soils containing high amounts of organic c (37-73 g kg-1). in order to monitor the effects of al in the soil and quality of sub-superficial water, changes in the concentration of monomeric forms of al and their activities in the soil solution need further study.
