Turning the Tide from Cars to Active Transport: Policy Recommendations for New Zealand

Background: Despite national-level efforts to encourage active transport in New Zealand since 2005, rates of active transport have continued to decline in most parts of the country, with negative impacts on health and the environment. / Purpose: We describe the development of key policy recommendations for active transport in New Zealand as an outcome of multi-sectoral discussions held at The Active Living and Environment Symposium (TALES; www.otago.ac.nz/active-living-2019; Dunedin, New Zealand; February 2019). The goal was to establish a set of priority recommendations to inform active transport decision-making in central and local government, public health units and regional sports trusts in New Zealand. / Project Description: The development of recommendations was planned and led by a working group consisting of ten TALES symposium delegates working in academia, industry and non-governmental organisations with prior work experience in central/local government and the private sector. Symposium delegates provided input prior to the symposium (delegates submitted 1-3 policy recommendations); during the symposium (delegates challenged/discussed/modified the first draft of recommendations at a dedicated final day session); and after the symposium (delegates provided feedback on the second draft of recommendations and associated actions). Using an online survey, the working group members also independently evaluated importance and feasibility of each recommended action before inclusion in the document. The final 13 recommendations (and 39 associated actions) were grouped across four broad categories: A) Evaluation, governance and funding; B) Education and encouragement/promotion; C) Engineering (infrastructure, built environment); and D) Enforcement and regulations. The report aligns with the New Zealand government’s increased focus on wellbeing, walking, cycling, public transport and Vision Zero approach, and recommends national targets for walking, cycling and public transport by 2050. The report was officially launched in April 2019. Initial discussions of recommendations with relevant stakeholders were conducted in four major urban centres in April-May 2019. / Conclusions: This cross-sector effort resulted in a report that has the potential to stimulate the development of a new active transport strategy for New Zealand; prompt setting of targets and monitoring progress/outcomes; and inform New Zealand’s response to the World Health Organization’s Global Action Plan on Physical Activity 2018-2030. Key policy recommendations for active transport in New Zealand include: making a national-level commitment to change; establishing a nationally coordinated and funded programme of education and promotion of active transport; creating a commitment to design cities for people and not for cars; and developing a regulatory system that encourages the use of active transport

Development of key policy recommendations for active transport in New Zealand: A multi-sector and multidisciplinary endeavour

Background: Despite national-level initiatives to encourage active transport (AT) in New Zealand since 2005, rates of AT have continued to decline in most parts of the country, with negative impacts on health and the environment. This article describes the development of key policy recommendations for increasing AT in New Zealand. The goal was to establish a cohesive set of priority recommendations to inform AT decision-making in central and local government, district health boards, public health units and regional sports trusts in New Zealand. Project description: The development of policy recommendations was a planned outcome of multi-sectoral discussions held at The Active Living and Environment Symposium (TALES; Dunedin, New Zealand; February 2019). A ten-member working group consisting of TALES symposium delegates working in academia, industry and non-governmental organisations led the development of the recommendations. Symposium delegates contributed their expertise to draft recommendations and reports prior to, during and after the symposium. Importance and feasibility of each recommended action were independently evaluated by working group members. The final set of 13 policy recommendations (and 39 associated actions) included: making a national-level commitment to change; establishing a nationally coordinated and funded programme of education and promotion of AT; making a commitment to design cities for people, not cars; and developing a regulatory system that encourages AT. The report aligns with the current New Zealand government's increased focus on wellbeing, walking, cycling, public transport and the Vision Zero approach. A final report was officially launched in April 2019 with presentations to stakeholders April-May 2019. Conclusions: This cross-sector effort resulted in a report with a set of recommendations designed to stimulate the development of a new AT strategy for New Zealand; prompt setting of targets and monitoring progress/outcomes; and inform New Zealand's response to the World Health Organization's Global Action Plan on Physical Activity 2018–2030

Circadian Rhythms in Visual Responsiveness in the Behaviorally Arrhythmic Drosophila Clock Mutant ClkJrk

An organism's biological day is characterized by a pattern of anticipatory physiological and behavioral changes that are governed by circadian clocks to align with the 24-h cycling environment. Here, we used flash electroretinograms (ERGs) and steady-state visually evoked potentials (SSVEPs) to examine how visual responsiveness in wild-type Drosophila melanogaster and the circadian clock mutant ClkJrk varies over circadian time. We show that the ERG parameters of wild-type flies vary over the circadian day, with a higher luminance response during the subjective night. The SSVEP response that assesses contrast sensitivity also showed a time-of-day dependence, including 2 prominent peaks within a 24-h period and a maximal response at the end of the subjective day, indicating a tradeoff between luminance and contrast sensitivity. Moreover, the behaviorally arrhythmic ClkJrk mutants maintained a circadian profile in both luminance and contrast sensitivity, but unlike the wild-types, which show bimodal profiles in their visual response, ClkJrk flies show a weakening of the bimodal character, with visual responsiveness tending to peak once a day. We conclude that the ClkJrk mutation mainly affects 1 of 2 functionally coupled oscillators and that the visual system is partially separated from the locomotor circadian circuits that drive bouts of morning and evening activity. As light exposure is a major mechanism for entrainment, our work suggests that a detailed temporal analysis of electrophysiological responses is warranted to better identify the time window at which circadian rhythms are most receptive to light-induced phase shifting

Gated Diffusion-controlled Reactions

The binding and active sites of proteins are often dynamically occluded by motion of the nearby polypeptide. A variety of theoretical and computational methods have been developed to predict rates of ligand binding and reactivity in such cases. Two general approaches exist, "protein centric" approaches that explicitly treat only the protein target, and more detailed dynamical simulation approaches in which target and ligand are both treated explicitly. This mini-review describes recent work in this area and some of the biological implications

Genome-Wide Association Studies in Dogs and Humans Identify ADAMTS20 as a Risk Variant for Cleft Lip and Palate

Cleft lip with or without cleft palate (CL/P) is the most commonly occurring craniofacial birth defect. We provide insight into the genetic etiology of this birth defect by performing genome-wide association studies in two species: dogs and humans. In the dog, a genome-wide association study of 7 CL/P cases and 112 controls from the Nova Scotia Duck Tolling Retriever (NSDTR) breed identified a significantly associated region on canine chromosome 27 (unadjusted p=1.1 x 10-13; adjusted p= 2.2 x 10-3). Further analysis in NSDTR families and additional full sibling cases identified a 1.44 Mb homozygous haplotype (chromosome 27: 9.29 – 10.73 Mb) segregating with a more complex phenotype of cleft lip, cleft palate, and syndactyly (CLPS) in 13 cases. Whole-genome sequencing of 3 CLPS cases and 4 controls at 15X coverage led to the discovery of a frameshift mutation within ADAMTS20 (c.1360_1361delAA (p.Lys453Ilefs*3)), which segregated concordant with the phenotype. In a parallel study in humans, a family-based association analysis (DFAM) of 125 CL/P cases, 420 unaffected relatives, and 392 controls from a Guatemalan cohort, identified a suggestive association (rs10785430; p =2.67 x 10-6) with the same gene, ADAMTS20. Sequencing of cases from the Guatemalan cohort was unable to identify a causative mutation within the coding region of ADAMTS20, but four coding variants were found in additional cases of CL/P. In summary, this study provides genetic evidence for a role of ADAMTS20 in CL/P development in dogs and as a candidate gene for CL/P development in humans

Where Does Mediator Bind In Vivo?

Background: The Mediator complex associates with RNA polymerase (Pol) II, and it is recruited to enhancer regions by activator proteins under appropriate environmental conditions. However, the issue of Mediator association in yeast cells is controversial. Under optimal growth conditions (YPD medium), we were unable to detect Mediator at essentially any S. cerevisiae promoter region, including those supporting very high levels of transcription. In contrast, whole genome microarray experiments in synthetic complete (SC) medium reported that Mediator associates with many genes at both promoter and coding regions. Principal Findings: As assayed by chromatin immunoprecipitation, we show that there are a small number of Mediator targets in SC medium that are not observed in YPD medium. However, most Mediator targets identified in the genome-wide analysis are false positives that arose for several interrelated reasons: the use of overly lenient cut-offs; artifactual differences in apparent IP efficiencies among different genomic regions in the untagged strain; low fold-enrichments making it difficult to distinguish true Mediator targets from false positives that occur in the absence of the tagged Mediator protein. Lastly, apparent Mediator association in highly active coding regions is due to a non-specific effect on accessibility due to the lack of nucleosomes, not to a specific association of Mediator. Conclusions: These results indicate that Mediator does not bind to numerous sites in the yeast genome, but rathe

Building Babies - Chapter 16

In contrast to birds, male mammals rarely help to raise the offspring. Of all mammals, only among rodents, carnivores, and primates, males are sometimes intensively engaged in providing infant care (Kleiman and Malcolm 1981). Male caretaking of infants has long been recognized in nonhuman primates (Itani 1959). Given that infant care behavior can have a positive effect on the infant’s development, growth, well-being, or survival, why are male mammals not more frequently involved in “building babies”? We begin the chapter defining a few relevant terms and introducing the theory and hypotheses that have historically addressed the evolution of paternal care. We then review empirical findings on male care among primate taxa, before focusing, in the final section, on our own work on paternal care in South American owl monkeys (Aotus spp.). We conclude the chapter with some suggestions for future studies.Deutsche Forschungsgemeinschaft (HU 1746/2-1) Wenner-Gren Foundation, the L.S.B.
