‘It’s a Harsh Fact of Life with the RMA’: neo-liberalism and the realities of community sports facility development by the private sector in New Zealand

Despite the importance of facilities as primary sites for delivery of leisure and sport services, there has been a scarcity of academic literature on the provision of community sports facilities and the processes through which they are developed. In particular, this paper provides empirical analysis of leisure facility provision with a focus on practice and experience of policy and planning actors. By employing a case study approach and semi-structured interviews, the study identified a sharp contrast between the discourse of neo-liberalism and the realities of a highly regulated environment for the private sector under a national legislation of New Zealand, namely the Resource Management Act 1991. While both public and private actors recognised benefits of the resource consent process in mitigating the negative environmental impacts and facilitating public input, the findings also revealed its potential impediments to both private and philanthropic developments and their potential resultant benefits to communities and social citizenship due to its costly, restrictive and undifferentiated nature. Consequently, the paper suggests that future research needs to examine empirical evidence of how social citizenship and citizen engagement are enhanced by both public and private sectors through planning and development of community sports facilities and services.     

Taking agricultural technologies to scale: experiences from a vegetable technology dissemination initiative in Tanzania

One of the widely suggested approaches to meet the increasing food demand of a substantially growing world population is sustainable intensification. We present a unique agricultural research and scaling programme in Tanzania, focusing on the key elements necessary for results related to: gender analysis; private sector engagement; social capital; improvement and adaptation; and programme performance monitoring and evaluation. Since 2014, more than 6000 farmers have benefited from either the adaptive research or the scaling component of the programme. Preliminary impact analysis results from six pilot locations indicate that programme participants realized significantly higher yields compared to non-participants. In addition to productivity improvements, introducing resistant and drought-tolerant elite vegetable varieties improved the resilience of the existing farming systems. Finally, considering the needs of both male and female participants had a positive impact on technology adoption rates and reach.

2020年河北省蔬菜监督抽检数据分析

目的:分析2020年河北省市场监督管理局发布的蔬菜监督抽检数据.方法:下载2020年河北省市场监督管理局发布的食品抽检相关通告,从蔬菜品种、蔬菜细类、不合格蔬菜检出详情及不合格项目等方面进行分析.结果:1199批次蔬菜10个蔬菜品种中,检出62批次不合格,平均不合格率为5.17％.鳞茎类蔬菜、芽菜类蔬菜等不合格率较高,不合格突出的蔬菜细类为韭菜、豆芽、芹菜等,不合格项目主要为农药残留,且禁用农药残留占总不合格项次的50％.结论:河北省蔬菜质量安全水平相对较好,但低于全国平均水平,超剂量使用农药、违规使用禁用农药仍是蔬菜质量安全的主要问题,仍需加强韭菜、豆芽、芹菜等高风险蔬菜的监管力度.

Understanding postorganic fresh fruit and vegetable consumers at participatory farmers’ markets in Ireland: reflexivity,trust and social movements

This paper examines how trusting relations between consumers and vendors of organic fresh fruits and vegetables (FFVs) in a particular type of farmers’ market (FM) in Ireland are established and maintained, and what the implications of this are. First, the food system is outlined, and then its attendant problems. These problems have led to various solutions, two of which are organic food and FMs. Then, the growth in these two areas is outlined, as is the accompanying growth in the academic literature on these two areas, some of which overlaps. Various pressures, including in particular the increasing distance food travels and disconnected stallholders and products at the FM, are suggested. In light of this, a need to apply an understanding of the reflexive consumer, trust and social movements is suggested. It is found that the consumers interviewed act reflexively by choosing to go to these FMs. They prioritize the trusting relationships built up through repeated personal contact at these FMs over and above organic certification. Along with and as part of this, they prioritize local, fresh, seasonal ‘chemical‐free’ FFVs over and above imported certified organic produce. Various aspects of collective identity formation, including modes of behaviour, objects and stories, and language, are involved in this process. These elements, to some extent, act as a buffer against the pressures of distance and disconnection. Along with this, the essential meaning of the word organic is, in this particular context, reconstructed to include various socio‐environmental values missing from some certified organic produce. The word postorganic is suggested. The main methodologies used are semistructured in‐depth interviews and participant observation.

A model for planning locations of temporary distribution facilities for emergency response

We propose a network flow model for dynamic selection of temporary distribution facilities and allocation of resources for emergency response planning. The model analyzes the transfer of excess resources between temporary facilities operating in different time periods in order to reduce deprivation. Numerical analysis shows that the location of temporary facilities is determined by the demand and supply points. This work contributes to the emergency response planning that requires a quick response for the supply of relief materials immediately after a disaster hits a particular area.     

Ratio-based design hour determination for airport passenger terminal facilities

To avoid both over-design and under-sizing of airport passenger terminal facilities such as security checkpoints, the infrastructure is designed for a specifically determined design load. As such, the design load is considered for a short period of time, usually an hour of operation, during which peak, though not necessarily maximum, demand occurs. For strategic planning applications, future design loads can be determined by either fictitious flight schedules or ratio-based models which forecast the relationship between design load and annual demand. This study presents two ratio-based methods which allow the direct determination of design hour loads (DHL) for passenger terminal facilities. The unsaturated DHL model considers the relationship between observed passenger flows in the terminal and aggregated annual demand data. The saturated DHL model includes several operational constraints which limit the actual DHL, such as limitations in the runway system or the fleet mix operating at an airport. Both models are applied to two real-world airports, for which the DHL of the security checkpoint facilities is estimated from large datasets covering multiple years. Results are significant at the 5 % level and suggest that the proposed ratio-based methods are appropriate for airport strategic planning applications.
