    Arguments regarding the importance of tobacco to convenience stores could impede the adoption of tobacco retail reduction policies. Although trade associations argue tobacco constitutes two-thirds of convenience store sales and drives footfall, few studies have tested these claims. We therefore examined the prevalence and characteristics of tobacco purchases at convenience stores in Dunedin, New Zealand. We conducted a postpurchase survey at 20 convenience stores, each visited for three 60 min intervals over a 4-week period. We used descriptive statistics to determine proportions and 95% CIs of transactions that contained tobacco and those that contained only non-tobacco items. We estimated the mean number of items purchased, the mean number of non-tobacco items purchased and mean expenditure on non-tobacco items. Fourteen per cent of transactions contained tobacco (n=95/679); of those, 64% comprised tobacco only. Only 5% of all transactions included both tobacco and non-tobacco products. The mean number of non-tobacco items purchased was 1.9 for transactions containing only non-tobacco products and 1.7 for transactions containing both tobacco and non-tobacco products. After excluding the cost of tobacco, people who purchased tobacco and non-tobacco products spent on average $5.11 on non-tobacco items, whereas people who purchased only non-tobacco items spent on average $6.85. Tobacco products constitute a small proportion of items purchased from Dunedin convenience stores and are typically not purchased with non-tobacco items. Our findings are inconsistent with arguments that most small retailers rely on tobacco sales.

    Introduction In 2017, the New Zealand (NZ) Government announced its intention to liberalize the sale and promotion of electronic nicotine delivery systems (ENDS), including permitting any outlet to sell ENDS. This research estimated the proportion of tobacco outlets selling ENDS prior to legislative change, documented ENDS point-of-sale (POS) marketing, and examined associations between ENDS availability and outlet type, area-level deprivation, study region, and proximity to a secondary school. Aims and Methods After drawing a proportional random sample of 281 tobacco outlets from two NZ regions that included convenience stores, supermarkets, and petrol stations, we conducted observational in-store assessments to record ENDS product ranges and promotions. Data were collected between October and December 2017 and analyzed using descriptive statistics and regression modeling. Results Of tobacco outlets sampled, 22% sold ENDS; these were typically convenience stores (85%) and located in high deprivation areas (53%). Of stores selling ENDS, products were visible at POS in 89% of stores, including 15% with self-service displays and 15% with displays adjacent to children’s products. ENDS advertising was present in 31% of the outlets and generally promoted ENDS as cheaper than smoked cigarettes. Conclusions Liberalizing access to ENDS could reduce harms caused by smoking; however, extensive use of POS promotions will reach children and young people as well as smokers. While reducing harm among smokers is important, policy makers also need to ensure that regulations protect children from ENDS promotions. Implications Careful regulation is required to ensure increases in ENDS availability are not accompanied by an increase in young people’s exposure to ENDS marketing at the POS.

    IntroductionNew Zealand’s Smokefree 2025 goal aims to greatly decrease the availability of tobacco. One option is to cease the sale of tobacco from convenience stores. However, tobacco companies and retail trade associations oppose this move and have argued that customers who purchase tobacco drive footfall and spend more than non-tobacco customers. The aim of this study is to test the validity of industry claims about the importance of tobacco to convenience stores.MethodsDuring November and December 2019, immediate postpurchase surveys were undertaken with customers on exit from a random sample of 100 convenience stores in two New Zealand cities. We estimated the mean number of items purchased, including tobacco and non-tobacco items, and mean expenditure on non-tobacco items.ResultsOf the 3399 transactions recorded, 13.8% included tobacco, of which 8.3% comprised tobacco only and 5.5% included tobacco and non-tobacco items. The mean number of transactions containing both tobacco ...

    Reducing the widespread retail availability of tobacco could help realize tobacco endgame strategies. We assessed New Zealand smokers' perceptions of five potential policies designed to reduce the retail supply of tobacco, relative to a "benchmark" policy of annual tobacco tax increases. A sample of 623 smokers was recruited from an internet panel. Participants evaluated one of six randomly assigned policy scenarios that would reduce tobacco outlet density: (1) no tobacco sold at alcohol on-licensed premises, (2) no tobacco sold within 500 m of a high school, (3) no tobacco sold within 1 km of any school, (4) tobacco sold only at pharmacies, and (5) tobacco sold only at half the existing liquor stores. Continued 10% annual tobacco tax increases served as a benchmark condition. Participants rated the likely effectiveness of one policy on preventing uptake by a 15-year-old susceptible never-smoker and supporting quitting by an adult smoker. Analyses involved pooled t tests and logistic regression. The policy scenarios in which tobacco was only sold at half the existing liquor stores or only at pharmacies were rated more likely to prevent youth smoking initiation, and at least as likely to help smokers to quit, relative to the benchmark policy. This is the first study to compare potential retail interventions against a measure known to reduce smoking prevalence. Policies that substantially reduce tobacco availability and remove it from smokers' usual places of purchase are perceived as being at least as effective in reducing smoking initiation and supporting cessation, as tax increases. Tobacco control advocates have proposed a range of policies to reduce tobacco retail outlet density, as part of endgame strategies. There are no published data on the relative effectiveness of different approaches, therefore it is unclear which would be most likely to reduce smoking prevalence. This study provides an insight into smokers' perspectives on the effectiveness of retail reduction strategies and indicates that some of these could be at least as effective in reducing initiation and promoting quitting as tax increases. Smokers' perceptions of the relative effectiveness of these policy options may help inform the advocacy efforts of the sector.

    Background In 2010, the New Zealand (NZ) government introduced an annual 10% tobacco excise tax increase. We examined retailers' adherence to recommended retail prices (RRP), and whether the RRP included the full tax increase. Methods We collected price data on three British American Tobacco (BAT) factory-made cigarette brands, (premium, mainstream, and budget), and one roll-your-own tobacco brand before and after the 2014 tax increase from a sample of tobacco retailers. We examined price increases in each tobacco brand and compared these with the RRP. The extent to which the excise tax increases had been included in the RRP since 2010 was estimated using data sourced from the Ministry of Health and NZ Customs. Findings The median increase in price from before to after the tax change was only 3% for the budget brand (461 retailers). This contrasted with the median of 8% for the premium brand (448 retailers), and 11% for both mainstream and roll-your-own brands (471 and 464 retai...

    In 2010, the New Zealand (NZ) government introduced an annual 10% tobacco excise tax increase. We examined retailers' adherence to recommended retail prices (RRP), and whether the RRP included the full tax increase. We collected price data on three British American Tobacco (BAT) factory-made cigarette brands, (premium, mainstream, and budget), and one roll-your-own tobacco brand before and after the 2014 tax increase from a sample of tobacco retailers. We examined price increases in each tobacco brand and compared these with the RRP. The extent to which the excise tax increases had been included in the RRP since 2010 was estimated using data sourced from the Ministry of Health and NZ Customs. The median increase in price from before to after the tax change was only 3% for the budget brand (461 retailers). This contrasted with the median of 8% for the premium brand (448 retailers), and 11% for both mainstream and roll-your-own brands (471 and 464 retailers, respectively). While many retail outlets made changes according to the RRP set by BAT, several did not comply. Our analyses suggest BAT may be undershifting excise tax on the budget brand, and overshifting tax on brands in other price partitions. Tobacco companies do not appear to be increasing the RRPs of budget brands in line with tobacco excise tax increases. The increasing price differential between budget brands, and mainstream and premium brands may undermine cessation and impede realisation of New Zealand's Smokefree 2025 goal.

    Conclusions about temporal changes in age and circumstances of first intercourse are generally derived from retrospective reports by people of various ages in cross-sectional studies, with an inherent assumption of no bias stemming from time since the event. We examined this assumption through repeated questions on age and circumstances of first heterosexual intercourse (FHI) at ages 21 and 38 in a birth cohort. Despite considerable movement in individual reports, there was no bias in reported age of FHI. However, a greater proportion of both men and women stated at the later assessment both partners had been equally willing (versus persuading or persuaded). The distribution of current views of the appropriateness of the timing did not differ markedly between assessments, although there were many individual changes. Reports of contraceptive usage were similar at the two assessments for men but differed among women, mainly through more reporting that they could not remember. These fi...

    Visuomotor integration (VMI), or the ability to copy designs, and 2 measures of executive function were examined in a predominantly low-income, typically developing sample of children (n = 467, mean age 4.2 years) from 5 U.S. states. In regression models controlling for age and demographic variables, we tested the interaction between visuomotor integration (design copying) and inhibitory control (pencil-tap) or verbal working memory (digit span) on 4 directly assessed academic skills and teacher-reported approaches to learning. Compared with children with both poor visuomotor integration and low inhibitory control, those on the higher end of the continuum in at least 1 of these 2 skills performed better across several dependent variables. This compensatory pattern was evident for longitudinal improvement in print knowledge on the Test of Preschool Early Literacy (TOPEL), with similar though marginally significant findings for improvement in phonological awareness (TOPEL) and teacher-rated approaches to learning on the Preschool Learning Behaviors Scale (PLBS). Of note, the same compensatory pattern emerged for concurrently measured receptive vocabulary on the Peabody Picture Vocabulary Test (PPVT), expressive vocabulary on the Woodcock-Johnson III (WJ), TOPEL phonological awareness, and teacher-rated approaches to learning. The consistent pattern of results suggests that strong visuomotor integration skills are an important part of school readiness, and merit further study. (PsycINFO Database Record

    Cost-utility analysis using the quality-adjusted life years (QALY) as an outcome measure to inform healthcare resource allocation is becoming more common. The Child Health Utility 9D (CHU9D) enables the calculation of utility values in children. Children were involved throughout its development to ensure it is child centred. To determine whether the CHU9D is responsive to the changing components of the dmfs+DMFS index score in children receiving dental care over a 1-year period. The study sample comprised children aged 6 to 9 years old who were enrolled in a split-mouth, placebo-controlled randomised controlled trial. All children had a comprehensive clinical examination including radiographs and health-related quality of life (HRQoL) was measured using the CHU9D at baseline and 1 year. Descriptive statistics was followed by bivariate analyses before effect sizes were calculated. A negative binomial model was fitted to assess whether the utility score predicted the components of decayed and filled teeth (combined primary and permanent teeth). Eighty (92%) children completed the CHU9D at baseline and follow-up. They presented with a mean baseline d3mfs+D3MFS of 6.7 (SD = 7.1), which rose to 7.3 (SD = 7.0) at follow-up. The mean CHU9D score improved from 0.88 to 0.90 from baseline to follow-up. No statistically significant relationships were found between caries status and the CHU9D score. The CHU9D was found to be unresponsive to the changing components of dental caries experience.

    In this rejoinder to Willis, Smagorinsky, and Douglas (this issue of Educational Researcher), the authors discuss how many of the points raised by Willis and Smagorinsky regarding their original article, which appeared in the March 2009 issue of Educational Researcher, are concerned less with the methods themselves than with different styles of science. The authors of this rejoinder examine their differing styles of science, using Stanovich's 2003 framework, and call for consilience and the understanding that multiple perspectives and methods are needed to solve the important and perplexing problems that students and teachers will face in the 21st century.

    The Individualizing Student Instruction (ISI) classroom observation and coding system is designed to provide a detailed picture of the classroom environment at the level of the individual student. Using a multidimensional conceptualization of the classroom environment, foundational elements (teacher warmth and responsiveness to students, classroom management) and instructional elements (teacher-child interactions, context, and content) are described. The authors have used the ISI system to document that children who share the same classroom have very different learning opportunities, that instruction occurs through interactions among teachers and students, and that the effect of this instruction depends on children's language and literacy skills. This means that what is effective for one child may be ineffective for another with different skills. With improving classroom observation systems, the dynamics of the complex classroom environment as it affects student learning can be ...
    ABSTRACT Statement of purpose Motor vehicle accidents (MVAs) are a significant cause of injury among youth aged 15-19. The crude rates of hospitalisation due to MVA were 101 and 153/100,000 persons (U.S. and NZ, respectively, 2000-2012).... more
    ABSTRACT Statement of purpose Motor vehicle accidents (MVAs) are a significant cause of injury among youth aged 15-19. The crude rates of hospitalisation due to MVA were 101 and 153/100,000 persons (U.S. and NZ, respectively, 2000-2012). During the same period, Southland, NZ reported a rate of 167/100,000. Differences in licencing age and overall fleet/road quality may contribute to some variances between countries. But knowledge gaps remain. Youth licensure and vehicle miles travelled (VMT) have declined worldwide, and, although injuries affect well-being, mental health with regard to transport isn’t researched. This presentation will discuss these gaps via preliminary findings from, and the testing of, a pilot study of youth in Southland.

    Geographic Information Systems (GIS) specialists from the Volcano Hazards Program (VHP) of the U.S. Geological Survey (USGS), including personnel at Menlo Park, California, the Cascades Volcano Observatory in Vancouver, Washington, the Alaska Volcano Observatory in Anchorage and Fairbanks, Alaska, the Hawaiian Volcano Observatory in Hawaii National Park, Hawaii, and the Smithsonian Institution Global Volcanism Program in Washington, DC, are developing a GIS response plan in the event of a volcano crisis. This plan, referred to as "Crisis GIS", outlines how VHP can ensure rapid, reliable delivery of spatial and ancillary information for data analysis and visualization at any required location during a volcanic crisis or event within the United States. An effective Crisis GIS needs the capacity to store multiple, large datasets, including: base layer data, elevation data, geologic maps, hazard assessment maps, satellite data, and aerial photography for volcanoes around the U...

    Abstract We examined gender differences in the first-grade transition, exploring child and classroom contributions to self-control and achievement in a rural sample. Teachers (n= 36) reported on children's (n= 172) initial adjustment difficulty and end-of-year self-control. Observed classroom organization and teacher-reported classroom chaos measured complementary aspects of classroom organizational climate. Children's literacy and mathematics skills were assessed in the fall and spring. Boys had more difficulty than girls ...

    ABSTRACT This study uses a large nationally representative data set (ECLS-K) of 5,181 students to examine the extent to which exposure to content and instructional practice contributes to mathematics achievement in fifth grade. Using hierarchical linear modeling, results suggest that more exposure to content beyond numbers and operations (i.e., geometry, algebra, measurement, and data analysis) contribute to student mathematics achievement, but there is no main effect for increased exposure on developing numbers and operations. Two significant interactions between exposure to specific content and racial composition of the classroom emerge. Specifically, as exposure to more diverse content increases, the classroom mathematics achievement gap among students in predominately Caucasian classrooms and those composed predominately of students of color appears to narrow. Findings are discussed with regard to promoting increased opportunities to learn mathematics for students in racially diverse classrooms.

    ABSTRACT Psychometric properties of 24 items from the fifth grade Early Childhood Longitudinal Study-Kindergarten Cohort Mathematics Teacher Questionnaire were investigated in a sample of 5,181 participants. These items asked teachers to report how often they had their classroom students engage in different mathematics content, skills and instructional practices. Exploratory factor analyses were employed to evaluate the underlying factor structure of the selected items. Results suggest that these items effectively measure three distinct latent constructs that are specific to mathematics instruction: Instructional Practices for Teaching Mathematics, Developing Number Sense, and Beyond Number Sense. These results support the use of this instrument as a guide for research and policy, or to inform teacher curriculum decisions.
