Knowledge of scientific inquiry (SI) is considered essential to the development of an individual's Scientific Literacy (SL) and therefore, SI is included in many international science education reform documents. Two previous large scale international studies assessed the SI understandings of students entering middle school and secondary students at the end of their formal K-12 science education. The purpose of this international project was to use the VASI-E to collect data on what primary level students have learned about SI in their first few years of school. This study adds to previous research to bridge the landscape of SI understandings now with representation from primary, middle and high school samples. A total of 4,238 students from 35 countries/regions spanning six continents participated in the study. The results show that globally, primary students are not adequately informed about SI for their age group. However, when compared with the students in the previous international studies (grades seven and 12), the primary students' understandings were surprisingly closer to the levels of understanding of SI of the secondary school students than those in the seventh grade study.

Many workers are subjected to incidents of rudeness and ignorance at work. Emerging evidence suggests that exposure to such incivility has an immediate impact on people's well-being and commitment. In this article we contribute to this nascent area of enquiry by investigating the role of discrete emotions in explaining how exposure to incivility translates into detrimental daily consequences, and by examining whether the role of emotions varies depending on whether incivilities occur during face-to-face versus online interactions. In a diary study of 69 workers, we find that face-to-face incivility has a pronounced daily impact on workers' exhaustion and turnover intention, and that this impact is mediated by increased feelings of sadness and anger, but not fear. In contrast, cyber incivility only affects workers' emotional exhaustion as a result of increases in sadness. Our findings provide insight into the mechanisms of daily effects of workplace incivility and the divergent daily effects of face-to-face versus cyber incivility. [ABSTRACT FROM AUTHOR]

Aim: To compare the efficacy of furosemide infusion with that of low-dose dopamine infusion in improving urine output and subsequent renal function in preeclamptic/eclamptic patients with oliguria in the immediate postpartum period. Design: Prospective randomised single blind clinical trial. Setting: Obstetric High Care Unit of King Edward VIII Hospital, a large referral tertiary hospital. Method: Eighty postpartum patients with severe preeclampsia/eclampsia with oliguria were enrolled. Hypovolaemia was corrected under central venous pressure (CVP) monitoring and urine output monitored for 4 hr. Patients who remained oliguric were randomly assigned to a continuous infusion of low-dose dopamine (3 µg/kg/min), or furosemide 5 mg/hr infusion, for 12 hr. In patients with no response after 12 hr, the drugs were switched and continued for a further 12 hr. A subgroup of patients who responded 4 hr after correction of hypovolaemia was observed for 12 hr. The primary outcome measured involved the comparison in urine output between the different drug regimes and the number of patients requiring haemodialysis. Secondary outcome measures involved assessment of serum urea and creatinine values in the two treatment groups. Results: Of the 80 patients enrolled, 20 improved their urine outputs within the 4-hr observation period. Sixty patients were randomised to furosemide or low-dose dopamine infusion. There was no statistical significant difference in the mean hourly urine output, rate of change in urine output over time and the mean urea or creatinine levels between the treatment groups. Ten percent of patients that failed on furosemide primarily, and 8.5% of patients that failed on initial low-dose dopamine, received haemodialysis. The difference in demographic and clinic data between these groups was not statistically significant. Conclusion: Administration of continuous infusion of furosemide showed comparable efficacy to low-dose dopamine infusion in ameliorating... [ABSTRACT FROM AUTHOR]

To create a prognostic model for complications of blood culture-proven typhoid fever in adults (≥15 y old), a retrospective cohort was assembled though review of the medical records of the hospitalized patients treated for typhoid fever over a 3-y period ending January 1995. Of the 59 patients included, 21 (35.6%) developed various complications of typhoid fever. No patient included died. Four baseline variables (abdominal pain, systolic blood pressure <100 mmHg, hypoalbuminaemia <32 g/l and laboratory evidence of disseminated intravascular coagulation) were independently associated with complications and were used to create a prognostic model. The prediction accuracy of the model was determined using the concordance index (c-index). The results (c-index, 0.915 [95% CI, 89.0-93.0]) showed that the model predicted complications significantly better than chance. The model stratified patients into 3 prognostic stages: low risk for complications (0%; stage I), intermediate risk (42.9%; stage II) and high risk (92.3%; stage III) (p=0.001). If validated in other settings, it will help clinicians in predicting complications in patients with blood culture-proven typhoid fever on admission. [ABSTRACT FROM AUTHOR]

This article examines the role of the United States Supreme Court in constraining federal intervention in response to white supremacist violence during the Reconstruction Period from 1866 to 1877. Contemporary research on the modern civil rights movement stresses the importance of a triad pattern of civil rights protest, white violence and federal intervention. Sociologists have devoted considerable efforts to analyze the modern civil rights movement. They have given little attention, however, to civil rights activity in the Reconstruction era 1865-1877. Social movement theorists contend that the political system's openness to change varies, thereby affecting the chances for successful collective protest. Research has shown that there is no consistent relationship between repression and social movement growth. Evidence indicates that repression can have both positive and negative effects on social movements. The Supreme Court's states' rights stance during Reconstruction had a major impact on the viability of a civil rights movement. Judicial decisions consigned almost all trials involving white violence and civil and voting rights violations to state courts.
