Socioeconomic status and neural processing of a go/no-go task in preschoolers: an assessment of the P3b
While it is well established that lower socioeconomic status (SES) is associated with poorer executive functioning (EF), how SES relates to the neural processing of EF in childhood remains largely unexplored. We examined how household income and parent education related to amplitudes of the P3b, an event-related potential component, during one EF task. We assessed the P3b, indexing inhibition and attention allocation processes, given the importance of these skills for academic success. Children aged 4.5-5.5 years completed a go/no-task, which assesses inhibitory control and attention, while recording EEG. The P3b was assessed for both go trials (indexing sustained attention) and no-go trials (indexing inhibition processes). Higher household income was related to larger P3b amplitudes on both go and no-go trials. This was a highly educated sample, thus results indicate that P3b amplitudes are sensitive to household income even within the context of high parental education. Findings build on the behavioral literature and demonstrate that SES also has implications for the neural mechanisms underlying inhibition and attention processing in early childhood.Published versio
Now we are six: lessons from New Zealand’s KiwiSaver
New Zealand’s KiwiSaver was introduced on 1 July 2007. New Zealand’s success with the ‘soft compulsion’ of automatic enrolment has been and is continuing to be an influence in the design of opt-out schemes in the UK and Ireland. While there have been numerous changes to KiwiSaver as outlined in this paper, six years on, the retirement saving scheme appears well accepted by the public and membership has exceeded most expectations.
New Zealand’s experience suggests that auto-enrolment and large incentives to entice people to remain opted-in may ensure initial take-up is high. It also suggests the incentives may be reduced significantly ex post with little impact on membership. Core tax-funded KiwiSaver subsidies have been both substantially reduced and not indexed while membership has continued to grow strongly.
Whether this auto-enrolment scheme, featuring generous provisions for withdrawals and contributions holidays, is sufficient to ensure that those who should be saving for their retirement are saving, and saving enough, is open to debate. If KiwiSaver is made compulsory, as some powerful lobbies propose, there are large complexities to resolve, including the future role of the universal state pension, New Zealand Superannuation.
Lessons from KiwiSaver on what to avoid in the design of a national retirement saving scheme may include: opening it to children; offering housing subsidies; allowing too many providers and privileging some of these as ‘default providers’; ignoring the issue of decumulation; and obscure objectives. Advantages over previous work-based retirement saving schemes include the portability of KiwiSaver accounts facilitated by the IRD’s role as a clearing house. New Zealand has also limited regressivity in the design of its very modest tax incentives, but at a cost: many save just the minimum required to maximise the subsidies.
The Working Paper surveys the first six years of KiwiSaver’s evolution to July 2013. In that time, the fundamental questions around its purpose and design have not been resolved. Is its purpose to enhance access to suitable wealth accumulation vehicles for those who have missed out on traditional work-based schemes? Or is it to reduce the pressures on the economy of an ageing population; or to solve the national saving problem? Will KiwiSavers in fact have more to spend during their retirement, or will they simply reduce other savings to compensate? In the long term, what are the implications for New Zealand’s overall pensions framework, and in particular the very successful universal state pension?
As 2014 is an election year, political parties are positioning themselves on KiwiSaver policy. In the meantime there is strong international interest in New Zealand’s retirement saving scheme, with its unique features such as auto-enrolment.
The Retirement Policy and Research Centre is pleased to publish KiwiSaver: Now we are six. It updates earlier working papers, including Working Paper 2010 KiwiSaver: lessons for Ireland. TheviewsinthisWorkingPaper’scommentaryarethoseoftheauthors
The Influence of Placement in a Co-Taught Inclusive Classroom on the Academic Achievement of General Education Students on the 2014 New York State ELA and Mathematics Assessments in Grades 6-8 in a Suburban New York School District
This study examined the influence of placement in a co-taught inclusive classroom on the academic achievement of general education students in Grades 6-8 in a suburban New York school district on the 2014 New York State ELA and Mathematics Assessments. Propensity score matching was utilized to select the sample to provide a balanced sampling technique. The final sample was comprised of 746 students in Grades 6-8 in a suburban New York upper middle class district during the 2013-14 school year. The variables that were included in this study were gender, socioeconomic status, attendance, ethnicity, past academic performance as measured by the 2013 New York State ELA and Mathematics Assessments, and placement in a co-taught inclusive classroom for ELA or Mathematics. Analyses were conducted using simultaneous and hierarchical multiple regression models, logistic regression, and factorial ANCOVA. Results of this study indicated that placement in a co-taught inclusive classroom had a statistically significant negative influence on the performance of Grades 6-8 general education students on both the 2014 New York State ELA Assessment and 2014 New York State Mathematics Assessment. Grades 6-8 general education students who were not placed in a co-taught inclusive classroom had a greater chance of being Proficient on both the 2014 New York State ELA Assessment and New York State Mathematics Assessment. Further research needs to be conducted on the co-taught inclusive classroom to determine why it had a negative influence on the academic achievement of general education students

Clothes make the rider? Equestrian competition dress and sporting identity
Tailored jackets, long boots and white gloves are clothes not normally associated with sport, yet they make up required competition dress within equestrianism. The modern equestrian sports of dressage and showjumping have their origins in the military and on the hunting field, and this highly formal, masculine style persists in contemporary equestrian circles. Perceived by many non-participants as archaic, comical and distinctly unsporty, equestrian competition dress requirements have remained relatively unchanged for a century and are one factor (amongst many others) that visibly marks equestrianism as different to most other sporting practices. This paper draws on an ethnographic study of equestrian sport in Britain in order to consider how participants today relate to and experience formal competition dress in the course of regular sporting activities. Formal competition dress is an important aspect of individual sporting identity for contemporary riders and is understood by participants to represent the unusual ethos of equestrian sport
Concerns with AED conversion: comparison of patient and physician perspectives.
When discussing AED conversion in the clinic, both the patient and physician perspectives on the goals and risks of this change are important to consider. To identify patient-reported and clinician-perceived concerns, a panel of epilepsy specialists was questioned about the topics discussed with patients and the clinician's perspective of patient concerns. Findings of a literature review of articles that report patient-expressed concerns regarding their epilepsy and treatment were also reviewed. Results showed that the specialist panel appropriately identified patient-reported concerns of driving ability, medication cost, seizure control, and medication side effects. Additionally, patient-reported concerns of independence, employment issues, social stigma, medication dependence, and undesirable cognitive effects are important to address when considering and initiating AED conversion
Robust study design is as important on the social as it is on the ecological side of applied ecological research
1. The effective management of natural systems often requires resource users to change their behaviour. This has led to many applied ecologists using research tools developed by social scientists. This comes with challenges as ecologists often lack relevant disciplinary training.
2. Using an example from the current issue of Journal of Applied Ecology that investigated how conservation interventions influenced conservation outcomes, we discuss the challenges of conducting interdisciplinary science. We illustrate our points using examples from research investigating the role of law enforcement and outreach activities in limiting illegal poaching
and the application of the theory of planned behaviour to conservation.
3. Synthesis and applications. Interdisciplinary research requires equal rigour to be applied to ecological and social aspects. Researchers with a natural science background need to access expertise and training in the principles of social science research design and methodology, in order to permit a more balanced interdisciplinary understanding of social–ecological system
The Success of Gay–Straight Alliances in Waterloo Region, Ontario: A Confluence of Political and Social Factors
This article outlines how gay–straight alliances (GSAs) work to connect youth with community resources, and outlines the political and social context of GSAs in Waterloo Region, Ontario, Canada. Fifteen individuals (youth, teachers, and a lesbian, gay, bisexual, transgender, and queer [LGBTQ] youth service provider) participated in interviews about the role of GSAs in creating supportive school environments for LGBTQ youth and their allies. Analyses of the interview data found that, apart from providing direct support to LGBTQ students, GSAs in Waterloo Region decrease isolation by connecting youth with other LGBTQ community members, events, and resources. This article discusses how the confluence of government and school board policy and community agency support facilitates the implementation, maintenance, and success of GSAs
Chemical ionization tandem mass spectrometer for the in situ measurement of methyl hydrogen peroxide
A new approach for measuring gas-phase methyl hydrogen peroxide [(MHP) CH_3OOH] utilizing chemical ionization mass spectrometry is presented. Tandem mass spectrometry is used to avoid mass interferences that hindered previous attempts to measure atmospheric CH_3OOH with CF_3O− clustering chemistry. CH_3OOH has been successfully measured in situ using this technique during both airborne and ground-based campaigns. The accuracy and precision for the MHP measurement are a function of water vapor mixing ratio. Typical precision at 500 pptv MHP and 100 ppmv H_2O is ±80 pptv (2 sigma) for a 1 s integration period. The accuracy at 100 ppmv H_2O is estimated to be better than ±40%. Chemical ionization tandem mass spectrometry shows considerable promise for the determination of in situ atmospheric trace gas mixing ratios where isobaric compounds or mass interferences impede accurate measurements
