Corporate Education and the Role of the Chief Learning Officer

This paper aims to present an overview on characteristics, roles and responsibilities of those who arc in charge. of the Corporate Educational Systems in several organizations from distinct industries in Brazil, based on a research carried out by the authors. The analysis compares what is available in the literature on this subject so that it may provide insights on how Brazilian companies have dealt with the difficult task of developing competences in their employees. Special attention is given to the Chief Learning Officer`s role (or the lack of it) - someone who was supposed to be in charge of the employees` development processes in a given organization. The results show that this role has not been a clear or unanimous concept yet, neither in terms of the functions to be performed nor the so-called strategic importance given to this sort of executive. This research is both exploratory and descriptive, and due to the use of intentional sample, the inferences are limited. Despite these limitations, its comments may enrich the discussion on this subject.

GREEN MANAGEMENT, CLIMATE CHANGE AND SMALL BUSINESS IN BRAZIL: IMPLICATIONS FOR TRAINING AND EDUCATION FOR SUSTAINABLE DEVELOPMENT

This paper presents the results of a study on the analysis of training needs regarding environmental (green) management and climate change topics in micro and small enterprises (MSEs) in Brazil and its implications on education for sustainable development. It reports on an e-mail survey of Brazilian small enterprises, whose results indicate that they are indeed interested in environmental management and climate change topics in an education for sustainable development context. The study indicates that proposals for courses on environmental management and climate change should follow a systemic perspective and take sustainable development into account. By applying factor analysis, it was found that the topics of interest can be grouped into thematic modules, which can be useful in the design of training courses for the top management leaders of those companies.

The Development of Science Education Research in Brazil and Contributions from the History and Philosophy of Science

Over the last 50 years a new research area, science education research, has arisen and undergone singular development worldwide. In the specific case of Brazil, research in science education first appeared systematically 40 years ago, as a consequence of an overall renovation in the field of science education. This evolution was also related to the political events taking place in the country. We will use the theoretical work of Rene Kaes on the development of groups and institutions as a basis for our discussion of the most important aspects that have helped the area of science education research develop into an institution and kept it operating as such. The growth of this area of research can be divided into three phases: The first was related to its beginning and early configurations; the second consisted of a process of consolidation of this institution; and the third consists of more recent developments, characterised by a multiplicity of research lines and corresponding challenges to be faced. In particular, we will analyse the special contributions to this study gleaned from the field known as the history and philosophy of science.

Biological features of a puzzling symbiotic association between the hermit crab Dardanus insignis and the porcellanid crab Porcellana Sayana (Crustacea)

The symbiotic lifestyle is widespread among porcellanid crabs, which maintain ecological and co-evolutionary associations with annelid polychaetes, poriferans, cnidarians, echinoderms, gastropod. mollusks, and other crustaceans such as shrimps and hermit crabs, among others. We investigated the ecological association between the hermit crab Dardanus insignis and the porcellanid Porcellana sayana, in southeastern Brazil. Porcellanid crabs, hermit crabs, and available shells were collected monthly from July 2001 to June 2003, with a shrimp boat equipped with two double-rig trawl nets. The majority of P. sayana specimens were collected in shells occupied by D. insignis (96.6%); a few were found in empty shells (3.4%). The catch of both symbionts and hosts increased with increasing depth, with the highest occurrence at 35 m. The F. sayana crabs of various sizes could be found solitary or forming aggregations of up to 14 individuals per host, showing no sex or size segregation. In spite of the high diversity of shell species occupied by the hermit crabs and also available in the field, only a few of them were also utilized by P. sayana. The majority (93%) of shells utilized by P. sayana also hosted other symbiont species, constituting the basis of extensive symbiotic complexes. Thus, the ecological relationship between D. insignis and P. sayana may be classified as a non-obligate and non-specific symbiosis that may also involve other facultative organisms such as sea anemones.

Influence of the reinforcement magnitude on omission effects

Reinforcement Omission Effects (ROEs), indicated by higher rate of responses after nonreinforced trials in a partial reinforcement schedule, have been interpreted as behavioral transient facilitation after nonreinforcement induced by primary frustration, and/or behavioral transient inhibition after reinforcement induced by demotivation or temporal control. The size of the ROEs should depend directly on the reinforcement magnitude. The present experiment aimed to clarify the relationship between reinforcement magnitude and the omission effects manipulating the magnitude linked to discriminative stimuli in a partial reinforcement FI schedule. The results showed that response rates were higher after omission than after reinforcement delivery. Besides, response rates were highest immediately after the reinforcement omission of a larger magnitude than of a smaller magnitude. These data are interpreted in terms of ROEs multiple process behavioral facilitation after nonreinforcement, and behavioral transient inhibition after reinforcement. (C) 2011 Elsevier B.V.

Assessment of the differential linear coherent scattering coefficient of biological samples

New differential linear coherent scattering coefficient, mu(CS), data for four biological tissue types (fat pork, tendon chicken, adipose and fibroglandular human breast tissues) covering a large momentum transfer interval (0.07 <= q <= 70.5 nm(-1)), resulted from combining WAXS and SAXS data, are presented in order to emphasize the need to update the default data-base by including the molecular interference and the large-scale arrangements effect. The results showed that the differential linear coherent scattering coefficient demonstrates influence of the large-scale arrangement, mainly due to collagen fibrils for tendon chicken and fibroglandular breast samples, and triacylglycerides for fat pork and adipose breast samples at low momentum transfer region. While, at high momentum transfer, the mu(CS) reflects effects of molecular interference related to water for tendon chicken and fibroglandular samples and, fatty acids for fat pork and adipose samples.

Something moves: a philosophical and ethical praise to the combat practicing as art and education

In this work we tried to produce a philosophic-ethic praise to the Martial Arts` combat practice, based in our years of Martial Arts training accompanied with studies of oriental and occidental Philosophy. Tracing a critical history of the changes happened to the Martial Arts we brought the concept of combat as a martial practice of life empowerment. Opposing this, we presented the notion of fight as a result of the capture that the war arts suffered because of the despotic empires. Besides, we demonstrated that the combat practice is simultaneously an artistic and educational activity, because it aims at the production of an immanence field witch is loyal to the event.

Education and the historiography of Ibero-American independence: elusive presences, many absences

This contribution analyses recent historiographical tendencies in research in the field of education at the time of the political emancipation of the former Spanish and Portuguese colonies in Latin America. The article briefly presents the complex educational scene in Latin America on the eve of the movements for independence. Due to the revolutionary character of the process of independence, it identifies educational history as one of the most significant absences in the historiography of independence. Notwithstanding, education has certainly been addressed by historians of education, mostly focusing on the colonial or postcolonial period, while largely neglecting the two decades after 1808. This indicates both the divide prevalent between historians of education and historians of independence and the rather nationalistic conceptual frame of existing scholarship.

Francoist Primary education: the schoolbook as an instrument of child indoctrination

The Francoist rule, mainly in its first decades, exerted a strong control upon education, which was left in the hands of the Catholic nationalist. Innumerous children`s schoolbooks were published driven by strong patriotic and religious bias. The authors aimed to shape the children`s minds based on the premises that supported the regimen: authority, hierarchy, order, abeyance, fear and devotion to God and the leader Francisco Franco. This paper analyzes the content of the elementary education books and shows how they were important instruments of child indoctrination marked by intolerance. The content and the images of the books contributed to construct an excluding national identity based on a heightened Catholic patriotism, stimulated heroism, martyrdom, child sacrifice, and hatred for the enemies of the religion and of ""mother Spain"".

Mycobacterium chelonae valve endocarditis resulting from contaminated biological prostheses

Objectives: A rapid-growing mycobacteria biological prosthetic valve (BPV) endocarditis related to prosthetic manufacturing process is described in Brazil. Methods: From 1999 to 2008, thirty-nine patients underwent BPV replacement due to culture-negative suspected endocarditis. All these cases had histological sections stained by Ziehl-Neelsen method. Clinical and microbiological data were reviewed in all acid-fast bacilli (AFB) positive cases. The 16S-23S internal transcribed sequence (ITS) was amplified using DNA extracted from paraffin-embedded samples, digested with restrictions enzymes and/or sequenced. Results: Eighteen AFB positive BPV (18/39)(46%) were implanted in 13 patients and were from the same manufacturer. Four of them were implanted in other hospitals. Thirteen BPV were histologically proven endocarditis and five showed a colonization pattern. The examination of six non-implanted ""sterile"" BPV from this manufacturer resulted in 5 AFB positive. Mycobacterium chelonae was the AFB identified by ITS restriction analysis and sequencing. Conclusions: Rapid-growing mycobacteria infections must be suspected and Ziehl-Neelsen stain always performed on histology of either early or late BPV endocarditis, particularly when blood cultures are negative.

The impact of simple donor education on donor behavioral deferral and infectious disease rates in Sao Paulo, Brazil

BACKGROUND: Studies have shown that human immunodeficiency virus (HIV) residual risk is higher in Brazilian than in US and European blood donors, probably due to failure to defer at-risk individuals in Brazil. This study assessed the impact of an educational brochure in enhancing blood donors` knowledge about screening test window phase and reducing at-risk individuals from donating. STUDY DESIGN AND METHODS: This trial compared an educational intervention with a blood center`s usual practice. The brochure was distributed in alternating months to all donors. After donating, sampled participants completed two questions about their HIV window period knowledge. The impact on HIV risk deferral, leaving without donation, confidential unit exclusion (CUE) use, and test positivity was also analyzed. RESULTS: From August to November 2007 we evaluated 33,940 donations in the main collection center of Fundacao Pro-Sangue/Hemocentro de Sao Paulo in Sao Paulo, Brazil. A significant (p < 0.001) pamphlet effect was found on correct responses to both questions assessing HIV window phase knowledge (68.1% vs. 52.9%) and transfusion risk (91.1% vs. 87.2%). After adjusting for sex and age, the pamphlet effect was strongest for people with more than 8 years of education. There was no significant pamphlet effect on HIV risk deferral rate, leaving without donation, use of CUE, or infectious disease rates. CONCLUSION: While the educational pamphlet increased window period knowledge, contrary to expectations this information alone was not enough to make donors self-defer or acknowledge their behavioral risk.

Long-Term Prospective, Randomized, Controlled Study Using Repetitive Education at Six-Month Intervals and Monitoring for Adherence in Heart Failure Outpatients The REMADHE Trial

Background-The effectiveness of heart failure disease management proarams in patients under cardiologists` care over long-term follow-up is not established. Methods and Results-We investigated the effects of a disease management program with repetitive education and telephone monitoring on primary (combined death or unplanned first hospitalization and quality-of-life changes) and secondary end points (hospitalization, death, and adherence). The REMADHE [Repetitive Education and Monitoring for ADherence for Heart Failure] trial is a long-term randomized, prospective, parallel trial designed to compare intervention with control. One hundred seventeen patients were randomized to usual care, and 233 to additional intervention. The mean follow-up was 2.47 +/- 1.75 years, with 54% adherence to the program. In the intervention group, the primary end point composite of death or unplanned hospitalization was reduced (hazard ratio, 0.64; confidence interval, 0.43 to 0.88; P=0.008), driven by reduction in hospitalization. The quality-of-life questionnaire score improved only in the intervention group (P<0.003). Mortality was similar in both groups. Number of hospitalizations (1.3 +/- 1.7 versus 0.8 +/- 1.3, P<0.0001), total hospital days during the follow-up (19.9 +/- 51 versus 11.1 +/- 24 days, P<0.0001), and the need for emergency visits (4.5 +/- 10.6 versus 1.6 +/- 2.4, P<0.0001) were lower in the intervention group. Beneficial effects were homogeneous for sex, race, diabetes and no diabetes, age, functional class, and etiology. Conclusions-For a longer follow-up period than in previous studies, this heart failure disease management program model of patients under the supervision of a cardiologist is associated with a reduction in unplanned hospitalization, a reduction of total hospital days, and a reduced need for emergency care, as well as improved quality of life, despite modest program adherence over time.

In vivo biological performance of a novel highly bioactive glass-ceramic (Biosilicate (R)): A biomechanical and histomorphometric study in rat tibial defects

This study aimed to investigate bone responses to a novel bioactive fully crystallized glass-ceramic of the quaternary system P(2)O(5)-Na(2)O-CaO-SiO(2) (Biosilicates (R)). Although a previous study demonstrated positive effects of Biosilicate (R) on in vitro bone-like matrix formation, its in vivo effect was not studied yet. Male Wistar rats (n = 40) with tibial defects were used. Four experimental groups were designed to compare this novel biomaterial with a gold standard bioactive material (Bioglass (R) 45S5), unfilled defects and intact controls. A three-point bending test was performed 20 days after the surgical procedure, as well as the histomorphometric analysis in two regions of interest: cortical bone and medullary canal where the particulate biomaterial was implanted. The biomechanical test revealed a significant increase in the maximum load at failure and stiffness in the Biosilicate group (R) (vs. control defects), whose values were similar to uninjured bones. There were no differences in the cortical bone parameters in groups with bone defects, but a great deal of woven bone was present surrounding Biosilicate (R) and Bioglass (R) 45S5 particulate. Although both bioactive materials supported significant higher bone formation; Biosilicate (R) was superior to Bioglass (R) 45S5 in some histomorphometric parameters (bone volume and number of osteoblasts). Regarding bone resorption, Biosilicate (R) group showed significant higher number of osteoclasts per unit of tissue area than defect and intact controls, despite of the non-significant difference in the osteoclastic surface as percentage of bone surface. This study reveals that the fully crystallized Biosilicate (R) has good bone-forming and bone-bonding properties. (C) 2011 Wiley Periodicals, Inc.

Effect of a sequential education and monitoring programme on quality-of-life components in heart failure

Aims Trials of disease management programmes (DMP) in heart failure (HF) have shown controversial results regarding quality of life. We hypothesized that a DMP applied over the long-term could produce different effects on each of the quality-of-life components. Methods and results We extended the prospective, randomized REMADHE Trial, which studied a DMP in HF patients. We analysed changes in Minnesota Living with Heart Failure Questionnaire components in 412 patients, 60.5% male, age 50.2 +/- 11.4 years, left ventricular ejection fraction 34.7 +/- 10.5%. During a mean follow-up of 3.6 +/- 2.2 years, 6.3% of patients underwent heart transplantation and 31.8% died. Global quality-of-life scores improved in the DMP intervention group, compared with controls, respectively: 57.5 +/- 3.1 vs. 52.6 +/- 4.3 at baseline, 32.7 +/- 3.9 vs. 40.2 +/- 6.3 at 6 months, 31.9 +/- 4.3 vs. 41.5 +/- 7.4 at 12 months, 26.8 +/- 3.1 vs. 47.0 +/- 5.3 at the final assessment; P<0.01. Similarly, the physical component (23.7 +/- 1.4 vs. 21.1 +/- 2.2 at baseline, 16.2 +/- 2.9 vs. 18.0 +/- 3.3 at 6 months, 17.3 +/- 2.9 vs. 23.1 +/- 5.7 at 12 months, 11.4 +/- 1.6 vs. 19.9 +/- 2.4 final; P<0.01), the emotional component (13.2 +/- 1.0 vs. 12.1 +/- 1.4 at baseline, 11.7 +/- 2.7 vs. 12.3 +/- 3.1 at 6 months, 12.4 +/- 2.9 vs. 16.8 +/- 5.9 at 12 months, 6.7 +/- 1.0 vs. 10.6 +/- 1.4 final; P<0.01) and the additional questions (20.8 +/- 1.2 vs. 19.3 +/- 1.8 at baseline, 14.3 +/- 2.7 vs. 17.3 +/- 3.1 at 6 months, 12.4 +/- 2.9 vs. 21.0 +/- 5.5 at 12 months, 6.7 +/- 1.4 vs. 17.3 +/- 2.2 final; P<0.01) were better (lower) in the intervention group. The emotional component improved earlier than the others. Post-randomization quality of life was not associated with events. Conclusion Components of the quality-of-life assessment responded differently to DMP. These results indicate the need for individualized DMP strategies in patients with HF.

Glycemia and prognosis of patients with chronic heart failure-Subanalysis of the Long-term Prospective Randomized Controlled Study Using Repetitive Education at Six-Month Intervals and Monitoring for Adherence in Heart Failure Outpatients (REMADHE) trial

Background Heart failure and diabetes often occur simultaneously in patients, but the prognostic value of glycemia in chronic heart failure is debatable. We evaluated the role of glycemia on prognosis of heart failure. Methods Outpatients with chronic heart failure from the Long-term Prospective Randomized Controlled Study Using Repetitive Education at Six-Month Intervals and Monitoring for Adherence in Heart Failure Outpatients (REMADHE) trial were grouped according to the presence of diabetes and level of glycemia. All-cause mortality/heart transplantation and unplanned hospital admission were evaluated. Results Four hundred fifty-six patients were included (135 [29.5%] female, 124 [27.2%] with diabetes mellitus, age of w50.2 +/- 11.4 years, and left-ventricle ejection fraction of 34.7% +/- 10.5%). During follow-up (3.6 +/- 2.2 years), 27 (5.9%) patients were submitted to heart transplantation and 202 (44.2%) died; survival was similar in patients with and without diabetes mellitus. When patients with and without diabetes were categorized according to glucose range (glycemia <= 100 mg/dL [5.5 mmol/L]), as well as when distributed in quintiles of glucose, the survival was significantly worse among patients with lower levels of glycemia. This finding persisted in Cox proportional hazards regression model that included gender, etiology, left ventricle ejection fraction, left ventricle diastolic diameter, creatinine level and beta-blocker therapy, and functional status (hazard ratio 1.45, 95% CI 1.09-1.69, P = .039). No difference regarding unplanned hospital admission was found. Conclusion We report on an inverse association between glycemia and mortality in outpatients with chronic heart failure. These results point to a new pathophysiologic understanding of the interactions between diabetes mellitus, hyperglycemia, and heart disease. (Am Heart J 2010; 159: 90-7.)
