Rising food security concerns among New Zealand adolescents and association with health and wellbeing

The current paper explores recent changes in food insecurity among adolescents and determine if food security concerns are associated with poorer wellbeing. Data were collected as part of two nationally representative surveys of the health and wellbeing of high-school students in New Zealand in 2007 and 2012. In 2012, 11% of young people reported food security concerns often or always, with 33% reporting food security concerns occasionally/sometimes. The prevalence of food security concerns at both frequencies increased significantly from 2007 (8% and 28%, respectively). Young people with food security concerns were more likely to report poor indicators of health and wellbeing, including truancy, poor general health, mental health concerns and obesity. Our findings highlight the growing concerns of food insecurity reported by adolescents in New Zealand. Interventions that address food security for families may provide a tangible means of promoting the healthy development of children and young people.     

建筑垃圾资源化利用实证研究

鉴于日益严峻的垃圾围城现象,以西咸北环线高速公路建设工程为依托,调研了该项目的企业用地、所缴纳税额、建筑垃圾原料来源等内容,对建筑垃圾综合利用的应用政策、应用技术、典型示范效应的现状和存在问题进行分析,讨论了依托工程在项目管理、建厂成本、企业免税、原材料获取、运输成本、社会认知度方面的相关政策。研究认为,应借鉴国内外比较全面系统的建筑垃圾分类管理办法,制定国家层面的法律法规体系,规范建筑垃圾的资源化利用;省市层面要根据各地实际,合理规划布局并支持建筑垃圾综合利用;国家和地方管理部门应建立建筑垃圾综合利用的行业标准并参与到政府循环经济发展规划中;还可以通过政策支持、税收优惠、支持技术研发等方式,以管理带动建筑垃圾资源化利用事业的发展。

The spatial distribution of smoking violations on a no-smoking campus: Implications for prevention

ABSTRACT

Objective: The present study extends research on campus smoking bans by examining where smokers are violating the policy at a large university in the southeastern region of the United States. Participants: The data collection was conducted by one graduate student from the university in August of 2014. Methods: A global positioning system device was used to collect the geo-coordinates of littered cigarette butts as a proxy measure for smoking violations. Results: A hot spot analysis found a number of spatial concentrations on campus, largely around classroom and administrative buildings along with parking lots and garages. Conclusions: The implications of such findings can direct enforcement to target these areas in order to reduce offenses and fulfill the initial goals of policy-makers and university administrators who support smoke-free campuses.     

生物安全实验室活毒废水处理工艺研究

Vertical Farming: Social Work and Sustainable Urban Agriculture in an Age of Global Food Crises

Abstract

Environmental concerns, including issues of ecological justice, attention to sustainability, and focus on issues of food security have gathered increased momentum in social work. This article will trace the background of sustainable urban agriculture as a partial solution to the issue of global food insecurity and its impact on marginalised urban populations. It will review the development of a sustainable agricultural initiative called vertical farming and suggest that it holds promise for communities struggling with chronic food security problems. It will outline some tentative steps social work may consider in order to become more fully involved in support of vertical farming initiatives.     

On intra-annual consumption-poverty in the U.S: Response to SNAP and the importance of within-year variation

We use U.S. quarterly consumption data and decomposable poverty indexes to study consumption-based intra-annual poverty and its relationship to participation in the Supplemental Nutrition Assistance Program (SNAP). Intra-annual spells of consumption-poverty account for half of the incidence and one-third of the severity of all consumption-poverty among U.S. households. Households experiencing consumption-poverty for at least one quarter, but not for the whole year, are more likely to self-select into SNAP than the general population but less likely to do so than those who are poor for the year. SNAP participation, in turn, reduces annual and intra-annual poverty.
