Distance Education in Another Register: Uses and Appropriation of Technologies in Teacher Education

The article explores the relationships between distance education, information and communication technologies and teacher education. Its focus is on the interactive media and its uses in an in-service teacher education program, in Brazil, and on the ways the teachers used the technologies doing their own appropriateness. It departs from the presuppositions of the society of knowledge, that is, the close relationships between new technologies, continuing professional development and social inclusion, arguing that this paradigm is an ideological discourse. The article shows how the teachers have used the technologies in creative ways, calling the attention to the importance of this teachers` abilities as a basic skill to facing the challenges of the society of knowledge itself.

Child psychiatry takes to the streets: A developmental partnership between a university institute and children and adolescents from the streets of Sao Paulo, Brazil

Objective: High levels of domestic violence, mental illness, and alienation from authorities are associated with high incidence of children/adolescents living on the streets in low and middle income countries. The Equilibrium Project (Programa Equilibrio) was created to facilitate social reintegration through a virtual partnership between an academic psychiatric institute and highly vulnerable children and adolescents living on the streets, in group shelter with supervision, and in other high risk situations. Methods: Descriptive presentation of qualitative data and analysis of preliminary empirical data collected over a 24-month period. Results: Dialogue between academic professionals, street children, and city officials shaped The Equilibrium Project over the last 2 years. The program has progressively moved from a professional clinic setting to a community-based but protected activity center with recreational and professional services and an emphasis on linkage with social service agencies, city government and law enforcement officials in an academic research context. A total of 351 patients have been served of whom virtually all were neglected by their parents, 58.4% report physical or sexual abuse, 88.89% have been diagnosed with a psychiatric disorder, 40.4% drug use. After 2 years of operation, 63.5% (n = 223) successfully completed or continue in treatment and 34.8% (n = 122) were reunited with their families. Conclusions and Practice implications: Program development guided by consumer input led to a successful program offering professional services in a protected community setting that facilitates social reintegration by providing ""go between"" services integrating relationships between alienated consumers and formal psychiatric, pediatric, social service, and criminal justice systems.

Outpatient treatment with intravenous antimicrobial therapy and oral levofloxacin in patients with febrile neutropenia and hematological malignancies

The purpose of this study was to evaluate outcomes such as success of the initial therapy, failure of outpatient treatment, and death in outpatient treatment during intravenous antimicrobial therapy in patients with febrile neutropenia (FN) and hematological malignancies. In addition, clinical and laboratory data and the Multinational Association for Supportive Care of Cancer index (MASCC) were compared with failure of outpatient treatment and death. In a retrospective study, we evaluated FN following chemotherapy events that were treated initially with cefepime, with or without teicoplanin and replaced by levofloxacin after 48 h of defervescence in patients with good general conditions and ANC > 500/mm(3). Of the 178 FN episodes occurred in 126 patients, we observed success of the initial therapy in 63.5% of the events, failure of outpatient treatment in 20.8%, and death in 6.2%. The success rate of oral levofloxacin after defervescence was 99% (95 out of 96). Using multivariate analysis, significant risks of failure of outpatient treatment were found to be smoking (odds ratio (OR) 3.14, confidence interval (CI) 1.14-8.66; p = 0.027) and serum creatinine levels > 1.2 mg/dL (OR 7.97, CI 2.19-28.95; p = 0.002). With regard to death, the risk found was oxygen saturation by pulse oximetry < 95% (OR 5.8, IC 1.50-22.56; p = 0.011). Using the MASCC index, 165 events were classified as low risk and 13 as high risk. Failure of outpatient treatment was reported in seven (53.8%) high-risk and 30 (18.2%) low-risk episodes (p = 0.006). In addition, death occurred in seven (4.2%) low-risk and four (30.8%) high-risk events (p = 0.004). Ours results show that MASCC index was able to identify patients with high risk. In addition, non-smoking, serum creatinine levels a parts per thousand currency sign1.2 mg/dL, and oxygen saturation by pulse oximetry a parts per thousand yen95% were protection factors.

Emerging Issues Concerning the Education of Speech and Language Pathologists and Audiologists in Brazil and South America

Diversity is one of the major characteristics of Brazil and all South America. This paper presents an overview of the current situation of the education of speech and language pathologists (SLP) and audiologists in Brazil and in several other countries of South America. This paper also discusses the main challenges shared by these countries. The discussion is focused on the mutual interferences between education and the areas of professional practice, cultural diversity and continued education. There are many emerging issues about the education of SLP and audiologists in South America. The suggested conclusion is that, despite the many differences, the South American SLP and audiologists` education would benefit from joint efforts and collaborative experiences.

The impact of a 17-day training period for an international championship on mucosal immune parameters in top-level basketball players and staff members

This investigation examined the impact of a 17-d training period (that included basketball-specific training, sprints, intermittent running exercises, and weight training, prior to an international championship competition) on salivary immunoglobulin A (SIgA) levels in 10 subjects (athletes and staff members) from a national basketball team, as a biomarker for mucosal immune defence. Unstimulated saliva samples were collected at rest at the beginning of the preparation for the Pan American Games and 1 d before the first game. The recovery interval from the last bout of exercise was 4 h. The SIgA level was measured using enzyme-linked immunosorbent assay and expressed as absolute concentrations, secretion rate, and SIgA level relative to total protein. The decrease in SIgA levels following training was greater in athletes than in support staff; however, no significant differences between the two groups were detected. A decrease in SIgA level, regardless of the method used to express IgA results, was verified for athletes. Only one episode of upper respiratory tract illness symptoms was reported, and it was not associated with changes in SIgA levels. In summary, a situation of combined stress for an important championship was found to decrease the level of SIgA-mediated immune protection at the mucosal surface in team members, with greater changes observed in the athletes.

Population demography and spatial distribution of the mantis shrimp Squilla biformis (Stomatopoda, Squillidae) from Pacific Costa Rica

The mantis shrimp Squilla biformis is the most conspicuous and abundant stomatopod captured during benthic trawling operations off the Pacific coast of Costa Rica. Due to its abundance, this species is considered a potential fisheries resource for the region. Nevertheless, its life history is practically unknown. The present study describes the population demography, spatial distribution and behaviour of S. biformis from Pacific Costa Rica. The population was principally composed of individuals between 20 and 32 mm carapace length (CL), forming 2 age groups. Individuals of 35 to 45 mm CL and > 45 mm CL were poorly represented. We assume that larger individuals are more frequent at greater depths (probably on the continental slope), thus out of the reach of the fishing vessels used in our study. Males outnumbered females, as observed in other stomatopods. Visual evidence of their behaviour demonstrates that the adults in this species possess a benthic and pelagic life style. Largest numbers of individuals (50% of the total) were found between 240 to 260 m, the same bathymetric range that was historically occupied by commercial shrimps. This shift may be related to intense fishing activities. We observed a synchronized moulting of females and males during less luminous (third and fourth) lunar phases. The evolutionary development of a group moulting system could confer advantages to S. biformis in comparison to other stomatopods whose moulting process is individual and asynchronous.

First isolation and molecular characterization of Ehrlichia canis in Costa Rica, Central America

The present study investigated Ehrlichia species in blood samples from dogs suspected of clinical ehrlichiosis, using molecular and isolation techniques in cell culture. From a total of 310 canine blood samples analyzed by 16S rRNA nested PCR, 148 (47.7%) were positive for Ehrlichia canis. DNA from Ehrlichia chaffeensis or Ehrlichia ewingii was not detected in any sample using species-specific primers in separated reactions. Leukocytes from five PCR-positive dogs were inoculated into DH82 cells; successful isolation of E. canis was obtained in four samples. Partial sequence of the dsb gene of eight canine blood samples (including the five samples for in vitro isolation) was obtained by PCR and their analyses through BLAST showed 100% of identity with the corresponding sequence of E. canis in GenBank. This study represents the first molecular diagnosis, isolation, and molecular characterization of E. canis in dogs from Costa Rica. (C) 2010 Elsevier Ltd. All rights reserved.
