Um estudo de caso da marca da empresa Wilson, Sons LogÃstica
Os estudos relacionados ao valor da marca para as organizações utilizam diversas abordagens – alguns estão focados na análise qualitativa, outros na análise financeira (STOBART, 1994), existem os estudos que focam
apenas na perspectiva das empresas ou apenas na perspectiva dos consumidores (KELLER, 1998) e também encontramos uma abordagem mais complexa, em que o valor da marca é um conjunto de ativos e passivos que precisam ser analisados dentro de alguns critérios (AAKER, 2000). Seja como for, todos esses autores tentam demonstrar a necessidade das organizações em focar suas estratégias na marca, para que as mesmas decidam pelos modelos mais adequados as suas realidades empresariais. De acordo com Keller (1998), uma marca tem valor quando os consumidores reagem mais favoravelmente ao produto a partir do momento que a conhecem e a identificam. Muitas vezes esse conhecimento prévio da mesma facilita a tomada de decisão com relação à compra de um produto ou serviço e até dispensa informações extras a respeito das organizações produtoras desses produtos ou prestadoras de tais serviços. Como a escolha da marca e da melhor forma de divulgação da mesma são decisões muito importantes para uma organização, pode-se considerar válido em muitos casos a realização de uma pesquisa de marketing. Para Churchill e Peter (2000), esta é definida como a função que liga o consumidor, o cliente e o público ao profissional de marketing por meio de informações. No entanto, é preciso que seja feita uma avaliação criteriosa da utilização ou não
de pesquisa de marketing, pois ela normalmente envolve custo e tempo, o que muitas vezes as organizações não estão dispostas a despender
A meta-analysis of resuscitative endovascular balloon occlusion of the aorta (REBOA) or open aortic cross-clamping by resuscitative thoracotomy in non-compressible torso hemorrhage patients
Background The objective of this systematic review and meta-analysis was to determine the effect of REBOA, compared to resuscitative thoracotomy, on mortality and among non-compressible torso hemorrhage trauma patients. Methods Relevant articles were identified by a literature search in MEDLINE and EMBASE. We included studies involving trauma patients suffering non-compressible torso hemorrhage. Studies were eligible if they evaluated REBOA and compared it to resuscitative thoracotomy. Two investigators independently assessed articles for inclusion and exclusion criteria and selected studies for final analysis. We conducted meta-analysis using random effect models. Results We included three studies in our systematic review. These studies included a total of 1276 patients. An initial analysis found that although lower in REBOA-treated patients, the odds of mortality did not differ between the compared groups (OR 0.42; 95% CI 0.17–1.03). Sensitivity analysis showed that the risk of mortality was significantly lower among patients who underwent REBOA, compared to those who underwent resuscitative thoracotomy (RT) (RR 0.81; 95% CI 0.68–0.97). Conclusion Our meta-analysis, mainly from observational data, suggests a positive effect of REBOA on mortality among non-compressible torso hemorrhage patients. However, these results deserve further investigation
Safety and effectiveness of propranolol in severely burned patients: systematic review and meta-analysis
Background The objective of this systematic review was to determine the effectiveness and safety of propranolol compared to placebo or usual care for improving clinical relevant outcomes in severely burned patients (TBSA \u3e20%). Methods Relevant articles from randomized controlled trials were identified by a literature search in MEDLINE, EMBASE, and CENTRAL. We included trials involving patients with a severe burn (\u3e20% of total body surface area affected). Trials were eligible if they evaluated propranolol and compared to usual care or placebo. Two investigators independently assessed articles for inclusion and exclusion criteria and selected studies for the final analysis. We conducted a meta-analysis using a random-effects model. Results We included ten studies in our systematic review. These studies randomized a total of 1236 participants. There were no significant differences between propranolol and placebo with respect to mortality (RD −0.02 [95% CI −0.06 to 0.02]), sepsis (RD −0.03 [95% CI −0.09 to 0.04]), and the overall hospital stay (MD −0.37 [−4.52 to 3.78]). Propranolol-treated adults had a decrease in requirements of blood transfusions (MD −185.64 [95% CI −331.06 to −40.43]) and a decreased heart rate (MD −26.85 [95% CI −39.95 to −13.75]). Conclusions Our analysis indicates that there were no differences in mortality or sepsis in severely burned patients treated with propranolol compared with those who had usual care or placebo. However, the use of propranolol in these patients resulted in lower requirements of blood transfusion and lower values of heart rate. The evidence synthesized in this systematic review is limited to conclude that propranolol reduces the length of hospital stay among severely burned patients. Future trials should assess the impact of propranolol on clinically relevant outcomes such as mortality and adverse events

Estudio de susceptibilidad a antibioticos de cepas de Acinetobacter baumannii aisladas de pacientes de los hospitales de Curico, Talca y Linares
51 p.Muchos patógenos que se encuentran en el ambiente hospitalario y ambulatorio son resistentes a varias clases de antimicrobianos y es, cada vez más común, que sean resistentes a prácticamente todos los antibacterianos disponibles, dejando muy pocas alternativas para el tratamiento de las infecciones causadas por ellos, en especial en bacilos gramnegativos no fermentadores como es el caso de Acinetobacter baumannii. El objetivo de este trabajo fue determinar la susceptibilidad antibiótica en cepas de Acinetobacter baumannii que fueron recolectadas periódicamente durante cinco meses en los hospitales de Curicó, Talca y Linares. Para esto fue necesario conocer la susceptibilidad de la bacteria, el tipo de muestra de la cual se aisló y los antibióticos que se utilizaron en los distintos centros hospitalarios consultados. Una vez aislada e identificada, la bacteria, se determinó la susceptibilidad antibiótica frente a ocho antimicrobianos usando el método de difusión en agar (antibiograma), además se hizo un estudio de concentración mÃnima inhibitoria empleando el método de dilución en agar para el cual se utilizaron cinco antibióticos distintos, los que fueron analizados mediante el programa estadÃstico SPSS 15.0, por el Método Chi- cuadrado. La mayorÃa de las muestras de los pacientes provenÃan de los servicios de Unidad de Cuidados Intensivos (UCI), del Servicio Atención Intermedia Quirúrgica (SAIQ) y de la Atención Pública en los centros hospitalarios estudiados. Las localizaciones más frecuentes de la infección fue la vÃa respiratoria en muestras de expectoración y aspirado traqueal
"My Child has Cerebral Palsy": Parental Involvement and Children's School Engagement
Engaged students tend to show school-committed behaviors (e.g., attend classes, get involved with the learning process), high achievement, and sense of belonging. However, students with disabilities are prone to show a lack of engagement with school due to the specific difficulties they have to handle. In fact, children with disabilities are likely to show poor participation in school when compared with children without disabilities. This poor involvement is related to their low autonomy to participate in the school activities, which, in turn, results in low school engagement. Parents play a crucial role in their childrens education. Parental involvement in school activities promotes autonomous behaviors and, consequently, school engagement. In fact, extant literature has shown close relationships between parental involvement, school engagement, and academic performance. Yet, parental involvement in school activities of children with Cerebral Palsy (CP) has received little direct attention from researchers. These children tend to display lower participation due to the motor, or cognitive, impairments that compromise their autonomy, and have a high likelihood to develop learning disabilities, with special incidences in reading and arithmetic. Therefore, our aim is twofold, to understand the parental styles; and how the perceived parental involvement in school activities is related to their children school engagement. Hence, 19 interviews were conducted with one of the parents of 19 children with CP. These interviews explored the school routines of children and the perceived involvement of parents in those routines. Additionally, children filled out a questionnaire on school engagement. Results show that the majority of the parents were clustered in the Autonomy Allowance and Acceptance and Support parental style, and the majority of their children were perceived as autonomous. Moreover, about a half of the children reported a high level of school engagement. Finally, neither childrens autonomous behaviors reportedThis study was conducted at Psychology Research Centre (UID/PSI/01662/2013), University of Minho, and supported by the Portuguese Foundation for Science and Technology and the Portuguese Ministry of Science, Technology and higher Education through national funds and co-financed by FEDER through COMPETE2020 under the PT2020 Partnership Agreement (FOCI-01-0145-FEDER-007653).

Perfil e distribuição da sÃndrome cólica em equinos em três unidades militares do Estado do Rio de Janeiro, Brasil
Este estudo teve como objetivo avaliar o perfil e a distribuição da sÃndrome cólica em eqüinos de três unidades militares no Estado do Rio de Janeiro, o Regimento Escola de Cavalaria (REsC), a Academia Militar das Agulhas Negras (AMAN) e o Esquadrão Escola de Cavalaria (EEC). No perÃodo entre 2003 e 2004, 770 eqüinos foram acompanhados para a ocorrência de casos clÃnicos de cólica. Realizou-se análise descritiva dos dados, e foram calculadas a taxa de incidência de cólica e a proporção de eqüinos acometidos. O teste do χ2 foi utilizado para avaliar a associação entre sÃndrome cólica e variáveis relativas à s caracterÃsticas dos eqüinos e do manejo. A incidência variou entre as unidades militares, 0,12 na AMAN, 0,21 no EEC e 0,95 casos/eqüino-ano no REsC, sendo acometidos 15% dos eqüinos da AMAN, 30% do EEC e 69% do REsC. A maior incidência foi de episódios de origem gástrica, 76,5%. Casos de reincidência foram elevados, sendo 62,5% no REsC, 36,7% na AMAN e 29,0% no EEC. A sÃndrome cólica estava significativamente associada à s variáveis unidade militar, sistema de criação, quantidade de grãos ingerido e suplemento mineral-vitamÃnico. As altas incidências, reincidências e proporção de animais acometidos observadas ocorreram de forma diferenciada nas três unidades, indicando que, apesar de possuÃrem como caracterÃstica comum pertencerem a unidades militares, os eqüinos formam um grupo heterogêneo no que diz respeito à ocorrência de sÃndrome cólica, provavelmente devido à s diferentes condições de manejo.This research aimed to verify the profile and distribution of colic syndrome in horses of three military units in Rio de Janeiro, Brazil, which were Regimento Escola de Cavalaria (REsC), Academia Militar das Agulhas Negras (AMAN), and Esquadrão Escola de Cavalaria (EEC). From 2003 to 2004, 770 horses were followed up for the incidence of colic cases. A descriptive analysis of clinical data, incidence of colic cases and rate of horses affected was established. Chi-squared test was used to evaluate the association among colic syndrome and variables related to horses characteristics and management. Colic syndrome incidence varied among military units as follows: 0.12 cases/horse-year at AMAN, 0.21 at EEC and 0.95 at REsC, affecting 15% of horses in AMAN, 30% in EEC and 69% in REsC. The highest incidence was of gastric episodes (76.5%). Recurrence cases were 62.5% in REsC, 36.7% in AMAN and 29.0% in EEC. Colic syndrome occurred associated with variables: military unit, management, amount of intake grains and supplemented mineral-vitamin. High incidence, recurrence and horses rate with colic were differentiated among the three units. Although the horses of military units had common characteristic , they formed a heterogeneous group in respect to colic syndrome occurrence, probably due to different management conditions
Has global deforestation accelerated due to the COVID-19 pandemic?
As the COVID-19 pandemic unfolded, questions arose as to whether the pandemic would amplify or pacify tropical deforestation. Early reports warned of increased deforestation rates; however, these studies were limited to a few months in 2020 or to selected regions. To better understand how the pandemic influenced tropical deforestation globally, this study used historical deforestation data (2004–2019) from the Terra-i pantropical land cover change monitoring system to project expected deforestation trends for 2020, which were used to determine whether observed deforestation deviated from expected trajectories after the first COVID-19 cases were reported. Time series analyses were conducted at the regional level for the Americas, Africa and Asia and at the country level for Brazil, Colombia, Peru, the Democratic Republic of Congo and Indonesia. Our results suggest that the pandemic did not alter the course of deforestation trends in some countries (e.g., Brazil, Indonesia), while it did in others (e.g., Peru). We posit the importance of monitoring the long-term effects of the pandemic on deforestation trends as countries prioritize economic recovery in the aftermath of the pandemic
