Solos do passado: origem e identifica??o
Ladeira, Francisco Sergio Bernardes;
Revista Brasileira de Ciência do Solo , 2010, DOI: 10.1590/S0100-06832010000600001
Abstract: soils are a result of the interaction between forming factors and processes in the different landscapes of the earth′s land surfaces. long-term processes change landscapes and associated soil profiles. these changes result from gradual or catastrophic processes of eolian, tectonic and climatic or even human impact, and are generally irreversible, destroying the associated soils. nevertheless, in particular situations soils may remain preserved in a specific area of the ancient landscape, embedded in sedimentary and volcanic sequences, resulting in the so-called paleosols. paleosols are a source of relevant information for a variety of purposes and are particularly valuable in providing evidence for reconstructing past terrestrial ecosystems and environments, mainly in the case of rare or nonexistent fossils; for the characterization of ancient atmospheres and paleoclimate, stratigraphic correlations, as indicator of old relief surfaces, of mineral concentrations; pedogenetic paleoprocesses and sedimentary processes, and as indicator of continental drift in geoarchaeology. in brazil, studies of paleosols are still rare and relatively recent, beginning in the 1970s, in contrast to the united states of america and europe, where such studies are quite advanced and widely reported. this review discusses relevant concepts in paleopedology, with the purpose of arousing some interest, mainly among the pedologic scientific community of brazil, where little research work on this subject is available yet.
Evidence based practice guidelines for management of low back pain: physical therapy implications
Ladeira, Carlos E.;
Brazilian Journal of Physical Therapy , 2011, DOI: 10.1590/S1413-35552011000300004
Abstract: background: low back pain (lbp) is the most common disorder seen in physical therapy practice. there are several hundred clinical trials on the management of lbp. to summarize these trials, researchers wrote evidence based practice (ebp) guidelines. this article reviewed the implications of ebp guidelines recommendations for physical therapy practice. objectives: to review the recommendations for conservative management of lbp published in ebp guidelines since 2002. methods: searches were performed on the following databases: google web searching engine, medline, cochrane library, and the guideline clearing house. guidelines published in english and addressing conservative management of lbp were included. results: thirteen multidisciplinary and three mono-disciplinary guidelines met the inclusion criteria. lbp was triaged into three groups: with red flags, with radiculopathy, or non-specific. patients without red flags could be safely managed without specialist referral. patient education was recommended for all patients with lbp. there was an agreement to advise spine manipulation for patients with acute and sub-acute non-specific lbp. there was a consensus to recommend exercises for acute, sub-acute, and chronic lbp. few guidelines addressed conservative management of lbp with radiculopathy. overall, the guidelines did not offer specific advice for manipulation (hypomobility or instability) and exercise (stabilization or directional preference). conclusion: multidisciplinary guidelines focused on primary care and lacked details significant for physical therapy practice. there is a need for mono-disciplinary physical therapy guidelines to improve the balance between evidence and professional relevance.
Avalia??o do benefício a longo prazo da imunoterapia específica na rinoconjuntivite polínica
Nunes,Carlos; Ladeira,Susel;
Revista Portuguesa de Imunoalergologia , 2012,
Abstract: aim: evaluate long-term clinical efficacy two years after suspension of specific immunotherapy in patients with seasonal rhino--conjunctivitis. methodology: during five years an immunotherapy extract of grass pollens by subcutaneous route (scit) was administered to a group of 16 patients with moderate to severe rhinoconjunctivitis, monosensitised to grass pollens. the mean age of the patients was 27.8 years, with homogeneous sex distribution. after the terminus of scit the group was followed during two more years to evaluate symptomatology and the use of rescue medication. we have compared this group with another group who did not perform scit. all patients received weekly information about forecasts and grass pollens count in their residential area. an informatics sheet was used to evaluate daily 4 degrees of 6 parameters including nasal and eye symptoms and any use of medication used to control the disease. as statistical method anova test and student’s t test were used for analyse mean differences between the two groups. for correlations the spearman method was used. results: during the immediate 2 years after scit in the active group, a significant reduction on symptoms (42%) as well as a reduction on the use of rescue medication (59%) were observed (p<0.01), compared with the control group. the eye symptoms had a higher reduction than nasal symptoms after the suspension of scit. conclusions: a long -term efficacy of scit was verified even after the suspension of the treatment, with reduction on symptoms and on use of rescue medication. the use of a daily score of symptoms and needs on rescue medication was very useful to the majority of the patients. providing regular information to patients regarding pollen count was considered useful to promote a self -management and a better quality of life to the patients

Abstract: One of the factors that influence consumer behavior is the search of uniqueness, the measurement of this behavior has been done using the scale called consumers' need for uniqueness - CNFU (TIAN; BEARDEN; HUNTER, 2001). Therefore, this study presents two complementaryobjectives. First we try to adapt and validate the scale consumer need for uniqueness - CNFU among Brazilian consumers. Later, we seek to relate consumers’ need for uniqueness with the consumption behavior of consumer the live alone - singles. This approach is motivated by the presupposition that these consumers havestrong uniqueness behavior. For empirical validation of the model we collected 210 questionnaires with singles in the metropolitan area ofPorto Alegre – Brazil. Results provide a new scale adapted to measure the need for uniqueness in a singular group of consumers. Then, the three hypotheses relating CNFU with singles’ consumer behavior have been validated. Finally, it is understood that singles' consumers analyzed demonstrate to seek uniqueness in their purchasing decisions.

Abstract: The objective of the article is to identify the perceived value of average consumers of pickup trucks. We conducted exploratory, qualitative research with consumers located in the Greater Porto Alegre-RS. We used laddering as a technique for collecting and analyzing data. The survey sample consisted of 13 respondents, this number being determined through theoretical saturation of the responses, with the identification of complete value chains. Data analysis was divided into four key steps: (a) compile data on individual attributes, consequences and values, (b) drafting table ladders, (c) creation of the matrix of commitment and hierarchical map of values and (d) definition of prevailing perceptions and the relationship that creates the perceived value of average consumers of pickup trucks. O presente artigo traz como objetivo identificar a percep o de valor nos consumidores de caminhonetes picapes médias. Para isto, foi realizada uma pesquisa qualitativa exploratória com consumidores localizados na regi o da grande Porto Alegre-RS. Para tanto, utilizou-se como técnica de coleta e análise dados a laddering. A amostra da pesquisa contou com 13 entrevistados, sendo este número determinado após atingir a satura o teórica das respostas, com a identifica o de cadeias completas de valor. A análise dos dados foi divida em quatro etapas centrais: (a) compila o dos dados isolados em atributos, consequências e valores; (b) elabora o da tabela de ladders, (c) cria o da matriz de implica o e mapa hierárquico de valores e (d) defini o das percep es dominantes e do relacionamento que gera o valor percebido para os consumidores de caminhonetes picapes médias. Logo após, foram feitas as considera es finais do trabalho.
