As orações subordinadas substantivas em função de sujeito: questões de ensino

This paper attempts to answer how the descriptive analysis of the substantive subordination clauses made within the realm of academic research can contribute to the effective teaching of those structures in the Elementary School. After showing how the subordination has been treated in grammar school and textbooks and pointing at some recurring problems in the presentation of the subject, we present the treatment of subordinate clauses with the function of subject in two descriptive grammars of Portuguese, in order to ascertain to what extent the relevant aspects of the description of those clauses are related to the traditional way of teaching. From those descriptive works, we selected some functional features considered to be essential for the treatment of the subject in the Elementary School.

Beeinflusst Stereotype Threat die Leseleistung von Jungen?

Ein durchgängiger Befund internationaler Schulleistungsvergleichsstudien bezieht sich auf die niedrigere Lesekompetenz von Jungen im Vergleich zu Mädchen (OECD, 2010). Ziel der vorliegenden Arbeit war, zu prüfen, welchen Einfluss negative Stereotype – im Sinne der Stereotype Threat-Theorie (Steele & Aronson, 1995) – auf die Leseleistung von Jungen haben. Basierend auf Befunden aus der Lese- und Stereotype Threat-Forschung wurde ein Mediator-Moderator-Modell des Stereotype Threat-Effekts (vgl. Schmader, Johns & Forbes, 2008) auf die Leseleistung von Jungen abgeleitet und überprüft. Um diese Fragestellungen zu beantworten, wurden zwei quasiexperimentelle Untersuchungen mit Schülern achter und neunter Klassen durchgeführt. An der ersten Untersuchung nahmen insgesamt 167 Schüler (n = 69 Jungen, n = 98 Mädchen) zweier Gymnasien in privater Trägerschaft teil. Um die Fragestellungen an einer weniger selektiven Stichprobe untersuchen zu können, erfolgte eine zweite Untersuchung mit Schülern (N = 441) öffentlicher Schulen und verschiedener Schulformen, wobei der Fokus ausschließlich auf den männlichen Schülern (n = 188 Jungen; n = 122 Gymnasiasten, n = 66 Realschüler plus) lag. Für beide Experimente kann zusammenfassend festgehalten werden, dass sich, entgegen der Erwartungen, kein leistungsmindernder Stereotype Threat-Effekt auf die Leseleistung von Jungen zeigte. Ferner konnten keine signifikante Mediatoren und Moderatoren eines leistungsmindernden Stereotype Threat-Effekts auf die Leseleistung von Jungen identifiziert werden. Ziel zukünftiger Forschung muss sein, den Einfluss negativer Stereotype auf die Leistungen männlicher Probanden im Sinne von Mitgliedern dominanter Gruppen zu untersuchen. Besonderes Augenmerk sollte auf die stereotypisierte Fähigkeitsdomäne gelegt werden. Weiterhin ist wichtig, der Frage nach zugrunde liegenden Prozessen und Voraussetzungen für das Erleben von Stereotype Threat nachzugehen. Studien weisen darauf hin, dass unterschiedlich stigmatisierte Gruppen unterschiedlich auf Stereotype Threat reagieren. Daher sollte der Fokus zukünftiger Forschung darauf liegen, die Prozesse und Voraussetzungen näher zu untersuchen, die für Mitglieder sonst positiv stereotypisierter Gruppen in solchen Situationen zum Tragen kommen.

THE BACON CHOW STUDY: THE RELATIONSHIP BETWEEN INFECTIOUS ILLNESS AND GROWTH OF INFANTS

Multiple dietary deficiencies and high rates of infectious illness are major health problems leading to malnutrition and limitation of growth of children in developing countries. Longitudinal studies which provide information on illness incidence and growth velocity are needed in order to untangle the complex interrelationship between nutrition, illness and growth. From 1967 to 1973, researchers led by Dr. Bacon Chow of the Johns Hopkins University School of Hygiene undertook a quasi-experimental prospective study in Suilin Township, Taiwan to determine the effects of a nutritional supplement to the diets of pregnant and lactating women on the growth, development and resistance to disease of their offspring. This dissertation presents results from the analysis of infant morbidity and postnatal growth.^ Maternal nutritional supplementation has no apparent effect on the postnatal growth or morbidity of infants. Significant sex differences exist in growth response to illness and in illness susceptibility. Male infants have more diarrhea and upper respiratory illness. Respiratory illness is positively associated with growth rate in weight in the first semester of life. Diarrhea is significantly negatively associated with growth in length in the second semester. Small-for-date infants are more susceptible to illness in general and have a different pattern of growth response than large-for-date infants.^ Principal components analysis of illness data is shown to be an effective technique for making more precise use of ambiguous morbidity data. Multiple regression with component scores is an accurate method for estimating variance in growth rate predicted by indepenent illness variables. A model is advanced in which initial postnatal growth rate determines subsequent susceptibility to nutritional stress and infection. Initial growth rate is a function of prenatal nutrition, but is not significantly affected by maternal supplementation during gestation or lactation. Critical evaluation is made of nutritional supplementation programs which do not afford disease control.^

Advance provision of emergency contraception for pregnancy prevention (Review)

Background Emergency contraception can prevent pregnancy when taken after unprotected intercourse.Obtaining emergency contraception within the recommended time frame is difficult for many women. Advance provision could circumvent some obstacles to timely use. Objectives To summarize randomized controlled trials evaluating advance provision of emergency contraception to explore effects on pregnancy rates, sexually transmitted infections, and sexual and contraceptive behaviors. Search strategy In November 2009, we searched CENTRAL, EMBASE, POPLINE,MEDLINE via PubMed, and a specialized emergency contraception article database. We also searched reference lists and contacted experts to identify additional published or unpublished trials. Selection criteria We included randomized controlled trials comparing advance provision and standard access (i.e., counseling whichmay ormay not have included information about emergency contraception, or provision of emergency contraception on request at a clinic or pharmacy). Data collection and analysis Two reviewers independently abstracted data and assessed study quality. We entered and analyzed data using RevMan 5.0.23. Main results Eleven randomized controlled trials met our criteria for inclusion, representing 7695 patients in the United States, China, India and Sweden. Advance provision did not decrease pregnancy rates (odds ratio (OR) 0.98, 95% confidence interval (CI) 0.76 to 1.25 in studies for which we included twelve-month follow-up data; OR 0.48, 95% CI 0.18 to 1.29 in a study with seven-month follow-up data; OR 0.92, 95% CI 0.70 to 1.20 in studies for which we included six-month follow-up data; OR 0.49, 95% CI 0.09 to 2.74 in a study with three-month follow-up data), despite reported increased use (single use: OR 2.47, 95% CI 1.80 to 3.40; multiple use: OR 4.13, 95% CI 1.77 to 9.63) and faster use (weighted mean difference (WMD) -12.98 hours, 95% CI -16.66 to -9.31 hours). Advance provision did not lead to increased rates of sexually transmitted infections (OR 1.01, 95% CI 0.75 to 1.37), increased frequency of unprotected intercourse, or changes in contraceptive methods.Women who received emergency contraception in advance were equally likely to use condoms as other women. Authors’ conclusions Advance provision of emergency contraception did not reduce pregnancy rates when compared to conventional provision. Results from primary analyses suggest that advance provision does not negatively impact sexual and reproductive health behaviors and outcomes. Women should have easy access to emergency contraception, because it can decrease the chance of pregnancy.However, the interventions tested thus far have not reduced overall pregnancy rates in the populations studied.

Letters from Daniel White to Andrew Hall, March 23, 1799

These two letters, both written on the same document, appear to be White's response to accusations from the father of one of his students at the Medford grammar school. Andrew Hall appears to have accused White of punishing his son too severely. In the letters, White denies Hall's accusations while defending his apparently strict approach to discipline. It is not certain whether both these letters were intended for Hall, or if one was written to another (unnamed) upset parent.

Letter from Stephen Longfellow to Daniel Appleton White, 1799 May 29

Stephen Longfellow wrote this letter in Portland, Maine on May 29, 1799; it was sent to his friend, Daniel Appleton White, in Medford, Massachusetts. In the letter, Longfellow describes the Election Day festivities among the "plebeans" in Portland, which he apparently found both amusing and upsetting. He compares the horses pulling their sleds to Don Quixote's horse, Rocinante. He also writes about mutual friends, including John Henry Tudor and Jabez Kimball, and bemoans the behavior of the current members of Phi Beta Kappa among the Harvard College undergraduates, whom he insists have sunk the society below its former "exalted station."
