Clitic Attachment in Brazilian Portuguese

This is the published version. Copyright 2006 Johns Hopkins University Press.Teaching and learning the placement of clitics in Brazilian Portuguese is a challenge, especially in written language, because of the many rules of clitic placement that characterize Portuguese normative grammars. These normative rules are applied more uniformly in Portugal than in Brazil because they were based originally on Peninsular Portuguese prosody. But regardless of how uniform they may be in Portugal, normative rules of clitic placement are a challenge to non-native speakers of Portuguese. The present study proposes a simplified approach to teaching normative rules to non-native students of Brazilian Portuguese, in the written and spoken language alike, based on a single rule of pronoun attachment

Phonetics in Second Language Acquisition: An Acoustic Study of Fluency in Adult Learners of Spanish

This is the published version. Copyright 1996 Johns Hopkins University Press.A phonetic definition of fluency in natural discourse makes it possible to develop a set of procedures to measure fluency empirically. An analysis of changes in oral communication skills of five American adult learners provides an illustration of how these procedures work. These adults participated in a five-week study abroad program in Spanish. Their overall language proficiency before their departure ranged from Intermediate Low to Advanced, on the ACTFL's OPI scale. Four participants moved to higher intra-major levels, but not to higher inter-major levels. The subjective analysis of the recordings shows that most of these changes are reflected in vocabulary acquisition and more ease in discourse interaction of the four participants. According to the procedures developed in the present analysis, only two participants improved their pronunciation. The results using the present procedures correlate with OPI results

It is anticipated that changes will gradually transform this printable textbook into an internet-based course taking greater advantage of the multimedia and interactivity available on the web. The project is the result of a 1999 grant provided by the United States Department of Education under the International Research and Studies Program, when José L. Martínez was the program officerUnited States Department of Education, under the International Research and Studies Progra

Evaluating the Usefulness and Properties of a Subjective Assessment of Brazilian Portuguese

This is the published version. Copyright 2002 Johns Hopkins University Press.This is an evaluation of a Brazilian self-assessment test. All questions on the test guide the students to evaluate themselves on their linguistic and socio-cultural skills in Brazilian Portuguese. The main points discussed in this article are (1) an item analysis, (2) the reliability of the test to determine the consistency of the results obtained by the instrument, (3) the construct validity, and (4) the creation of cutscores. Our analysis of the BP self-assessment was supported by the use of descriptive statistics, by a factorial analysis and by a reliability test to determine the psychometrics characteristics of the test. The major claim in this study is that this test is useful, valid and reliable, if used appropriately, especially with an audience of motivated students such as students going abroad, instead of students who take language classes only as a requirement in their school program

Diversity and ethics in trauma and acute care surgery teams: results from an international survey

Background Investigating the context of trauma and acute care surgery, the article aims at understanding the factors that can enhance some ethical aspects, namely the importance of patient consent, the perceptiveness of the ethical role of the trauma leader, and the perceived importance of ethics as an educational subject. Methods The article employs an international questionnaire promoted by the World Society of Emergency Surgery. Results Through the analysis of 402 fully filled questionnaires by surgeons from 72 different countries, the three main ethical topics are investigated through the lens of gender, membership of an academic or non-academic institution, an official trauma team, and a diverse group. In general terms, results highlight greater attention paid by surgeons belonging to academic institutions, official trauma teams, and diverse groups. Conclusions Our results underline that some organizational factors (e.g., the fact that the team belongs to a university context or is more diverse) might lead to the development of a higher sensibility on ethical matters. Embracing cultural diversity forces trauma teams to deal with different mindsets. Organizations should, therefore, consider those elements in defining their organizational procedures. Level of evidence Trauma and acute care teams work under tremendous pressure and complex circumstances, with their members needing to make ethical decisions quickly. The international survey allowed to shed light on how team assembly decisions might represent an opportunity to coordinate team member actions and increase performance

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Omecamtiv mecarbil in chronic heart failure with reduced ejection fraction, GALACTIC‐HF: baseline characteristics and comparison with contemporary clinical trials

Aims: The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTIC‐HF) trial. Here we describe the baseline characteristics of participants in GALACTIC‐HF and how these compare with other contemporary trials. Methods and Results: Adults with established HFrEF, New York Heart Association functional class (NYHA) ≥ II, EF ≤35%, elevated natriuretic peptides and either current hospitalization for HF or history of hospitalization/ emergency department visit for HF within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokinetic‐guided dosing: 25, 37.5 or 50 mg bid). 8256 patients [male (79%), non‐white (22%), mean age 65 years] were enrolled with a mean EF 27%, ischemic etiology in 54%, NYHA II 53% and III/IV 47%, and median NT‐proBNP 1971 pg/mL. HF therapies at baseline were among the most effectively employed in contemporary HF trials. GALACTIC‐HF randomized patients representative of recent HF registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressure < 100 mmHg (n = 1127), estimated glomerular filtration rate < 30 mL/min/1.73 m2 (n = 528), and treated with sacubitril‐valsartan at baseline (n = 1594). Conclusions: GALACTIC‐HF enrolled a well‐treated, high‐risk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation

The role of the output in language learning

This study uses linguistic output to identify cognitive processes of language learning, i.e. the internalization of specific language components and metalinguistic or metacognitive learning mechanisms. Given that these processes are present in discourse production, they indicate a significant role of speech production in foreign language learning. Furthermore, they serve as predictors of learning processes and can be used to model learning behavior. The data to support this claim were obtained in analyses of ten native speakers of Spanish learning Brazilian Portuguese in Brazil. We found that linking rules of phonology, which are different in Portuguese and Spanish, can be indicators of their language cognitive levels. Linking patterns indicate not only that the system is being learned, but also the transitions from one language proficiency level to another, such as from ―advanced-low‖ to ―advanced-mid,‖ as well as when a Spanish speaker has probably reached a ―superior level‖ in Brazilian Portuguese. Our study also indicates that some speakers seem to learn faster than others, given similar context for learning. This investigation suggests that that the reason behind the language gain difference in some learners is related to their attitude towards learning and their metalinguistic awareness, i.e. interest in teaching, self-corrected errors and sentence repair.Fulbright Foundation gran
