Comprehension and Vocabulary Strategies Using Related Tradebooks with Social Studies for Bilingual and Bicultural Middle School Students

In many schools, students from ethnic minority groups are immersed in secondlanguage reading curricula with minimal attention to their native language literacy (Droop & Verhoeven, 2003). These children face the challenge ofleaming to read in languages that they have not mastered orally. As a result, these second-language students can then experience considerable gaps in their understanding ofreading because reading instruction in any language strongly builds on oral language proficiency. For these reasons, second-language literacy learning is an enormous issue in our schools today (Goodman, Goodman, & Flores, 1984). This is why the author chose to research effective reading instruction for bilingual and bicultural students. After reviewing the research, the focus of this project was to explore comprehension and vocabulary strategies combined with content area themes and related trade books for bilingual and bicultural middle school students

The first international workshop on the role and impact of mathematics in medicine: a collective account

The First International Workshop on The Role and Impact of Mathematics in Medicine (RIMM) convened in Paris in June 2010. A broad range of researchers discussed the difficulties, challenges and opportunities faced by those wishing to see mathematical methods contribute to improved medical outcomes. Finding mechanisms for inter- disciplinary meetings, developing a common language, staying focused on the medical problem at hand, deriving realistic mathematical solutions, obtainin

Drug Abuse Treatment Beyond Prison Walls

The period surrounding release from prison is a critical time for parolees, bearing the potential for a drug-free and crime-free life in the community but also high risks for recidivism and relapse to drugs. The authors describe two projects. The first illustrates the use of a formal Delphi process to elicit and combine the expertise of treatment providers, researchers, corrections personnel, and other stakeholders in a set of statewide guidelines for facilitating re-entry. The second project is a six-session intervention to enable women to protect themselves against acquiring or transmitting HIV in their intimate relationships

Ocean circulation drifts in multi-millennial climate simulations: the role of salinity corrections and climate feedbacks

Low-resolution, complex general circulation models (GCMs) are valuable tools for studying the Earth system on multi-millennial timescales. However, slowly evolving salinity drifts can cause large shifts in climatic and oceanic regimes over thousands of years. We test two different schemes for neutralising unforced salinity drifts in the FAMOUS GCM: surface flux correction and volumetric flux correction. Although both methods successfully maintain a steady global mean salinity, local drifts and subsequent feedbacks promote cooling (≈ 4 °C over 6000 years) and freshening (≈ 2 psu over 6000 years) in the North Atlantic Ocean, and gradual warming (≈ 0.2 °C per millennium) and salinification (≈ 0.15 psu per millennium) in the North Pacific Ocean. Changes in the surface density in these regions affect the meridional overturning circulation (MOC), such that, after several millennia, the Atlantic MOC (AMOC) is in a collapsed state, and there is a strong, deep Pacific MOC (PMOC). Furthermore, the AMOC exhibits a period of metastability, which is only identifiable with run lengths in excess of 1500 years. We also compare simulations with two different land surface schemes, demonstrating that small biases in the surface climate may cause regional salinity drifts and significant shifts in the MOC (weakening of the AMOC and the initiation then invigoration of PMOC), even when the global hydrological cycle has been forcibly closed. Although there is no specific precursor to the simulated AMOC collapse, the northwest North Pacific and northeast North Atlantic are important areas that should be closely monitored for trends arising from such biases

The effect of community interventions on alcohol-related assault in Geelong, Australia

Alcohol has consistently been demonstrated to increase levels of aggression and violence, particularly in late night licensed venues. Since 2005, the City of Geelong in Australia has implemented a substantial number of interventions to reduce alcohol related violence, including a liquor accord, increased police surveillance, ID scanners, CCTV, a radio network and an alcohol industry sponsored social marketing campaign. The aim of the current study is to assess the individual and collective impact of community interventions on indicators of alcohol-related assaults in the Geelong region. This paper reports stage one findings from the Dealing with Alcohol-related problems in the Night-time Economy project (DANTE) and specifically examines assault rate data from both emergency department presentations, ICD-10 classification codes, and police records of assaults. None of the interventions were associated with reductions in alcohol-related as-sault or intoxication in Geelong, either individually or when combined. However, the alcohol industry sponsored social marketing campaign ‘Just Think’ was associated with an increase in assault rates. Community level interventions appeared to have had little effect on assault rates during high alcohol times. It is also possible that social marketing campaigns without practical strategies are associated with increased assault rates. The findings also raise questions about whether interventions should be targeted at reducing whole-of-community alcohol consumption

A cluster randomised controlled trial of a comprehensive accreditation intervention to reduce alcohol consumption at community sports clubs: study protocol

Introduction: Excessive alcohol consumption isresponsible for considerable harm from chronicdisease and injury. Within most developed countries,members of sporting clubs consume alcohol at levels above that of communities generally. Despite the potential benefits of interventions to address alcohol consumption in sporting clubs, there have been no randomised controlled trials to test the effectiveness of these interventions. The aim of this study is to examine the effectiveness of a comprehensive accreditation intervention with community football clubs (Rugby League, Rugby Union, soccer/association football and Australian Rules football) in reducing excessive alcohol consumption by club members.Methods and analysis: The study will be conducted in New South Wales, Australia, and employ a cluster randomised controlled trial design. Half of the football clubs recruited to the trial will be randomised to receive an intervention implemented over two and a half winter sporting seasons. The intervention is based on social ecology theory and is comprehensive in nature, containing multiple elements designed to decrease the supply of alcohol to intoxicated members, cease the provision of cheap and free alcohol, increase the availability and costattractiveness of non-alcoholic and low-alcoholic beverages, remove high alcohol drinks and cease drinking games. The intervention utilises a three-tiered accreditation framework designed to motivate intervention implementation. Football clubs in the control group will receive printed materials on topics unrelated to alcohol. Outcome data will be collected pre- and postintervention through cross-sectional telephone surveys of club members. The primary outcome measure will be alcohol consumption by club members at the club, assessed using a graduated frequency index and a seven day diary.Ethics and dissemination: The study was approved by The University of Newcastle Human Research Ethics Committee (reference: H-2008-0432). Study findings will be disseminated widely through peer-reviewed publications and conference presentations.<br /

Diverse functions for acyltransferase-3 proteins in the modification of bacterial cell surfaces

The acylation of sugars, most commonly via acetylation, is a widely used mechanism in bacteria that uses a simple chemical modification to confer useful traits. For structures like lipopolysaccharide, capsule and peptidoglycan, that function outside of the cytoplasm, their acylation during export or post-synthesis requires transport of an activated acyl group across the membrane. In bacteria this function is most commonly linked to a family of integral membrane proteins - acyltransferase-3 (AT3). Numerous studies examining production of diverse extracytoplasmic sugar-containing structures have identified roles for these proteins in O-acylation. Many of the phenotypes conferred by the action of AT3 proteins influence host colonisation and environmental survival, as well as controlling the properties of biotechnologically important polysaccharides and the modification of antibiotics and antitumour drugs by Actinobacteria. Herein we present the first systematic review, to our knowledge, of the functions of bacterial AT3 proteins, revealing an important protein family involved in a plethora of systems of importance to bacterial function that is still relatively poorly understood at the mechanistic level. By defining and comparing this set of functions we draw out common themes in the structure and mechanism of this fascinating family of membrane-bound enzymes, which, due to their role in host colonisation in many pathogens, could offer novel targets for the development of antimicrobials

Dealing with alcohol-related harm and the night-time economy

Alcohol-related problems are a major cause of social disorder and illness in Australia. In particular, problems associated with the night-time economies of urban and regional centres cause substantial community concern and are a considerable drain on police, community and health resources. The estimated cost of alcohol to the community is $15.3 billion, including costs associated with crime, violence, patient treatment, loss of productivity and premature deaths in 2004&ndash;05 (Collins 2008). Alcohol has also been identified as a factor in around three quarters of assaults and incidents of offensive behaviour on the street (Buss 1995). Previous research has identified several issues that contribute to the levels of short-term harm associated with risky drinking. These include: excessive consumption at licensed premises, consumption in public areas and lack of transport and security in entertainment precincts (Homel et al. 1992; Graham &amp; Homel 2008).Drinking in licensed venues is another predictor of harm and public disorder. More than half of offences occurring on the street have been associated with licensed premises in Australia (Buss 1995). A complex range of factors increase risky drinking and associated harms on licensed premises including: aspects of patron mix; levels of comfort, boredom, and intoxication; promotions that cause mass intoxication; and the behaviour of security/bouncers (Homel et al. 1992). Violence has also been shown to be perpetuated by poor venue management, lax police surveillance, lack of transport options for patrons, and inappropriate bureaucratic controls and legislation (Homel et al. 1992). This project aims to provide evidence-based knowledge regarding the implementation and impact of innovative local initiatives directed at alcohol-related harms.<br /

Tackling risky alcohol consumption in sport: a cluster randomised controlled trial of an alcohol management intervention with community football clubs

BACKGROUND: An increased prevalence of risky alcohol consumption and alcohol-related harm has been reported for members of sporting groups and at sporting venues compared with non-sporting populations. While sports clubs and venues represent opportune settings to implement strategies to reduce such risks, no controlled trials have been reported. The purpose of the study was to examine the effectiveness of an alcohol management intervention in reducing risky alcohol consumption and the risk of alcohol-related harm among community football club members. METHOD: A cluster randomised controlled trial of an alcohol management intervention was undertaken with non-elite, community football clubs and their members in New South Wales, Australia. Risky alcohol consumption (5+ drinks) at the club and risk of alcohol-related harm using the Alcohol Use Disorders Identification Test (AUDIT) were measured at baseline and postintervention. RESULTS: Eighty-eight clubs participated in the trial (n=43, INTERVENTION; n=45, CONTROL) and separate cross-sectional samples of club members completed the baseline (N=1411) and postintervention (N=1143) surveys. Postintervention, a significantly lower proportion of intervention club members reported: risky alcohol consumption at the club ( INTERVENTION: 19%; CONTROL: 24%; OR: 0.63 (95% CI 0.40 to 1.00); p=0.05); risk of alcohol-related harm ( INTERVENTION: 38%; CONTROL: 45%; OR: 0.58 (95% CI 0.38 to 0.87); p&lt;0.01); alcohol consumption risk ( INTERVENTION: 47%; CONTROL: 55%; OR: 0.60 (95% CI 0.41 to 0.87); p&lt;0.01) and possible alcohol dependence ( INTERVENTION: 1%; CONTROL: 4%; OR: 0.20 (95% CI 0.06 to 0.65); p&lt;0.01). CONCLUSIONS: With large numbers of people worldwide playing, watching and sports officiating, enhancing club-based alcohol management interventions could make a substantial contribution to reducing the burden of alcohol misuse in communities.<br /
