Revista de Administra??o Contemporanea , 2002, DOI: 10.1590/S1415-65552002000100009
Abstract: this study brings out the changes in the human resources area behavior within privatized companies. the research was developed before four steel metallurgy companies based in southeastern brazil. because the contextual research method was used, it was viable to appraise the internal and external settings together with the content and the processes related to such a transition. the use of the case study method thru both the interview and document analysis techniques led to a more comprehensive report of every case. it was then noticed that, although company privatizations have happened along the last nine years, the transition process itself is not over yet. the human resources professionals have lately and fortunately merged into the roles of strategists, change promoters, employees'advocates and management experts. in the past, such roles would mostly be operational, there used to be no freedom at all to develop tasks; behaviors were rather patronizing, and little concern with costs and available services were noticed.

Rege : Revista de Gest?o , 2006,
Abstract: The philosophy and models of the System of Compensation of administrators were analyzed to verify the degree of agreement with the good practice of corporate governance structure. The structure of corporate governance is made up of the Chairman of the Board of Directors, council members, CEO and the executive board. Literature reviewed disclosed only isolated aspects of governance and remuneration without any integrated format. Exploratory and descriptive methods were used for documentary research and field survey at the companies who had adhered to the differentiated levels of corporate governance of the S o Paulo Stock Exchange (level 1, level 2 and new market). Conclusions showed that remuneration of the council member was reasonable without considering the variable component found in executive board. The organizations used short term indicators for the remuneration system and were already formalizing procedures. However, greater internal as well as external transparency is required to make these procedures more public. O objetivo deste artigo foi identificar, descrever e analisar a filosofia e os modelos do Sistema de Remunera o de administradores e verificar se estavam alinhados com as boas práticas da estrutura de Governan a Corporativa. Comp em a estrutura de governan a corporativa o Presidente do Conselho de Administra o, os conselheiros, o Chief Executive Officer (CEO) e a diretoria executiva. Na revis o da literatura constatatou-se a existência de obras que estudaram aspectos de governan a e de remunera o separadamente, e n o de forma conjunta e integrada. Para a realiza o da pesquisa1 documental e do levantamento de campo foram utilizados os métodos exploratório e descritivo junto às empresas que aderiram aos níveis diferenciados de governan a corporativa da Bovespa (nível 1, nível 2 e novo mercado). Como principais conclus es, p de-se verificar que a remunera o do conselheiro é módica, n o contemplando o componente variável, como se viu na realidade da Diretoria Executiva. As organiza es utilizam indicadores para a concep o do sistema de remunera o de curto prazo e já est o atentas para a formaliza o dos procedimentos; no entanto, ainda necessitam divulgá-los com mais transparência, tanto interna quanto externamente.

Abstract: RESUMO Nos últimos anos, os casos de fraudes têm ocupado os meios de comunica o. O que pode contribuir para esta situa o é a velocidade das mudan as no ambiente organizacional e os controles internos n o estarem conseguindo acompanhar a mesma velocidade, aumentando assim o potencial de práticas de atos ilícitos. Por outro lado, o avan o tecnológico contribui para a informatiza o, possibilitando melhoria na detec o das fraudes. Esta investiga o se prop s a verificar como as empresas praticam a preven o às fraudes e, para tanto, efetuou-se um levantamento de campo junto as empresas de auto-pe as da regi o do ABC a partir de um critério de estratifica o tendo por base a lista do Sindipe as. Como resultado verificou-se que s o utilizados alguns controles internos. Porém, o assunto fraude ainda n o é tratado com a transparência e cuidados necessários e as empresas necessitariam incorporá-lo como risco inerente ao negócio. ABSTRACT For many years the fraud cases have been occupying the communication means. One fact that could contribute for this situation are the changes in the organizations are quick and the internal controls tend not follow the same quickness, increasing the practice potential of illicit acts. On the other hand, the technological improvement contributes for information technology, which improves the fraud detection. This investigation had as purpose to verify how the companies practice fraud prevents. For that, it was done a search in some automobile part companies in the ABC region.

Abstract: four wheat cultivars showing different reactions to al toxicity under field conditions and presenting a great variation in plant height were screened in nutrient solution with different concentrations of aluminum. the tall brazilian cultivar, 'bh-1146' was tolerant to 10 ppm of al; 'atlas-66' developed in north carolina was tolerant to 6 ppm but moderately tolerant to 10 ppm of aluminum. the dwarf cultivar tordo, a tom thumb source of dwarfism, was tolerant to 2 ppm but totally sensitive at 6 ppm. the mexican semidwarf cultivar siete cerros, a niorin-10 derivative, was sensitive to 2 ppm of al. parents, f1 and f2 generations from the crosses between tolerant ('bh-1146' and 'atlas-66') and sensitive ('tordo' and 'siete cerros') cultivars to 6 ppm were screened under 3 ppm and the same genotypes plus the backcrosses to both types of parents (bca and bcb) were screened at 6 ppm. parents, f1 and f2 progenies from bca and bcb involving the cross bh-1146/siete cerros were retested under 3 and 6 ppm of al. parents, f1 and f2 for the cross between 'bh-1146' and 'atlas-66' were screened under 6 and 10 ppm of al. at 2 and 3 ppm of al, parents, f1 and f2 from the cross tordo/siete cerros were studied. the results obtained suggest that 'bh-1146' differs from atlas-66, siete cerros and tordo by one pair of dominant gene. this pair of gene was efficient even at 10 ppm of aluminum, so should be used in a breeding program towards aluminum tolerance when high levels of this element are involved. the cultivar atlas-66 showed to have two pairs of dominant genes for al tolerance but when the aluminum concentration increased from 3 and 6 to 10 ppm these pairs of genes became less efficient. 'tordo' differs from 'siete cerros' by a pair of dominant gene for tolerance at 2 ppm of al. so 'tordo' would be useful as a source of tolerance when low levels of aluminum are involved. there was a gradual decrease of dominance of the pair or pairs of genes, or of the complex of genes which could be

Abstract: the cultivar siete cerros (p1) with tolerance to manganese toxicity and the cultivar bh-1146 (p2) showing sensitivity to manganese, were crossed. it was obtained the f1 and f2 generations of this cross. p1, p2, f1 and f2, where cultivated in nutrient solutions containing 0.11, 300, 600 and 1,200mg/l of manganese and they also were tested in other nutrient solution with 3mg/l of aluminum. the length of the central primary root of plants of each genotype under study after fifteen days being cultivated in nutrient solutions containing different manganese concentrations was used to evaluate the levels of tolerance to this element. the length of the central primary root of plants of each genotype measured 72 hours in a normal nutrient solution after a previous test in a treatment solution containing 3mg/l of aluminum was considered to evaluate the degree of tolerance to aluminum toxicity. the broad sense heritabilities values of root length considering increasing levels of manganese in the solution and 3mg/l of aluminum were high which indicated that the present variability found in the populations were in great part due to genetic origin. these results suggested that selections for tolerance to aluminum and manganese toxicities would be effective in early generations of a cross. the data showed that it would be possible to transfer by crossing bh-1146 and siete cerros the genetic tolerance to manganese from siete cerros into the bh-1146 germplasm or to obtain a siete cerros germplasm with aluminum tolerance from bh-1146 source.

Abstract: four wheat cultivars: bh-1146, c-3, siete cerros and brevor were tested in nutrient solution with 0, 1, 2, 3, 4, 5, 6 and 10mg/l of al3+. it was demonstrated that b-1146 and c-3 presented tolerance to 10mg/l of al3+ whereas brevor and siete cerros were sensitive to 1mg/l of al3+. it was considered tolerant the plant that was able to show root regrowth of the central primary root in the complete nutrient solution after a treatment in a solution containing a particular amount of aluminum. seeds of c-3 and siete cerros, considered parental lines, and the f1 and f2 populations from the crosses between them, were tested in nutrient solutions where 3, 6 and 10mg/l of aluminum were applied. the results showed that c-3 differed from siete cerros by one pair of dominant genes for tolerance at 3mg/l of aluminum. there was a gradual decrease of dominance of the gene pair responsable for the tolerance reaction when it was used 6mg/l of aluminum in the solution. the cultivar siete cerros differed from c-3 by one pair of dominant genes for susceptibility at 10mg/l of aluminum or c-3 differed from siete cerros by one dominant gene even at 10mg/l of al3+ if it was considered that the heterozygous individuals from the f1 and f2 populations showed reaction of susceptibility. heterozygous seedlings of f1 and f2, populations from the cross c-3/siete cerros, considered tolerant at 3mg/l of al3+, showed a decrease in tolerance at 6mg/l and susceptibility at 10mg/l. high broad sense heritability estimates (0.725 to 0.895) for aluminum tolerance to three different levels were obtained suggesting that selection for tolerance would be effective in the f2, population from the studied cross. it would be interesting to select for aluminum tolerance using solutions containing 10mg/l of al3+ when large f2 populations are provided being possible to eliminate the sensitive plants (recessive homozygous and heterozygous) and select the homozygous tolerant plants. on the other hand, when small f2 popu

Abstract: two experiments were conducted with the objective of studying the tolerance of wheat cultivars to 5 mg/l of al3+ in nutrient solutions. the tolerance was evaluated by measuring the root growth in an aluminum-free complete nutrient solution after a treatment of 48 hours, in aluminum solution with different levels of phosphorus, and with controlled ph and temperature (25 ± 1oc). in the first experiment eight cultivars were studied in treatment solutions with four levels of phosphorus (0; 15.5; 31.0 and 62.0 mg/l combined with three levels of ph (4.0; 5.0 and 6.0). the cultivars cnt-8 and siete cerros were sensitive and 'bh-1146', 'iac-18', 'iac-13', 'c-3', 'iac-17 and 'alondra- 4546' were tolerant to 5 mg/l of al3+ in the solutions with ph 4.0 and in absence of p. all cultivars were sensitive to al3+ when it was applied 15.5 mg/l of p and they were tolerant when was used 62 mg/l of p in the solutions, considering constant the ph 4.0. in solutions with the level of 31 mg/l of p and ph 4.0, the cultivars iac-18, bh-1146, iac-13 and c-3 showed tolerance and iac-17, alondra-4546, cnt-8 and siete cerros showed sensitivity to al3+ when it was used solution with ph 5.0 or 6.0 the cultivars presented tolerance being non dependent of p concentration, in consequence of the low activity of al3+ ions under these ph levels. the data demonstrated that tolerance to 5 m/l of al3+, besides the ph level was dependent on the p concentration in the solution. the cultivars bh-1146, iac-17 and siete cerros were studied in a second experiment in nutrient solutions with ph 4.0, containing five p concentrations (0; 1.55; 3.875; 7.75 and 15.5 mg/l). 'bh-1146' and 'iac-17 were tolerant and 'siete cerros' was sensitive to 5 mg/l of al3+ when it was added 0 and 1.55 mg/l of p into the treatment solution. when it was considered the p levels of 3.875; 7.75 and 15.5 mg/l all cultivates showed symptoms of al toxicity in their mots. there was an increase in p content in aereal part and root dry matter
Melhoramento do trigo: XIV. Correla??es entre a tolerancia à toxicidade a dois níveis de alumínio e altura das plantas com outros caracteres agron?micos em trigo

Bragantia , 1987, DOI: 10.1590/S0006-87051987000100010
Abstract: the standard height and al tolerant cultivar bh-1146 was crossed with semi-dwarf and al sensitive cultivars tobari-66 and siete cerros, in 1983. parents, f1's and f2's were tested for their reaction to 1 and 3 mg/l of al3+ in nutrient solution, in laboratory condition and evaluated for grain yield, plant height, number of spikes per plant, number of spikelets per spike, number of grains per spike, number of grains per spikelet, 100-grain-weight and spike length at maturity in an experiment using pots, under a screen house at experimental center of campinas, state of s?o paulo, brazil, in 1984. medium to high narrow sense heritability estimates were obtained for spike length, number of grains per spike, number of grain per spikelet and number of spikes per plant; and medium to low for other agronomic characteristics under study. plant height was significantly correlated with all the agronomic characteristics under study, except number of grains per spikelet and 100-grain-weight in the 'bh-1146' x 'tobari- 66' population. tolerance to al3+ toxicity was not associated with grain yield (except for the population from the cross bh-1146 x tobari-66 using 3 mg/l of al3+), plant height and number of grain per spikelet. the results suggested that it is possible to select plant types that combine al3+ tolerance, semi-dwarf height levels and high yield potential to be cultivated on aluminum acid soils. however, larger f2 populations would be required to ensure the frequency of desired recombinants.

Bragantia , 1987, DOI: 10.1590/S0006-87051987000100009
Abstract: the aluminum tolerant cultivar bh-1146 was crossed with the moderately tolerant cultivars iac-17 and alondra-s-46. parents, f1's and f2's were tested for their seeding reaction to 3 and 6 ppm of al3+ in nutrient solution. grain yield, plant height, number of spikes per plant, number of spikelets per spike, number of grains per spike, number of grains per spikelet, 100-grain-weight and spike lenght were also determined for these populations at maturity. all data were determined on an individual plant basis. broad sense heritability estimates for 100-grain-weight, head lenght and number of spikelets per spike were 0.73, 0.69 and 0.54 respectively. the values for plant height, number of grain per spike and per spikelet, and number of spike per plant ranged from 0.09 to 0.29. broad sense heritability for grain yield was low and equal to 0.13. narrow sense heritability estimates for all characteristics under study except for 100-grain-weigth and number of spikes per plant showed that a major part of the total genetic variation was associated with additive gene action. the phenotypic correlations between grain yield and all the other characteristics were positive and significant at 1% level for most of the populations. correlations between grain yield and number of spikelets per spike, in populations bh-1146 x iac-17, showed to be positive and significant only at the 5% probability level. grain yield and number of spikelets per spike in population bh-1146 x alondra-s-46 were negative and significantly correlated only at the 5% probability level. non significant correlations between grain yield and head lenght and between grain yield and plant height in population bh-1146 x alondra-s-46 and between grain yield and number of spikelets per spike in population iac-17 x alondra-s-46. tolerance to 3 and 6 ppm of al3+ in nutrient solutions was not associated with plant height (except for bh-1146 x iac-17 at 3 ppm of al3+), grain yield, number of grains per spikelet (head fertili
