Exploring motivation crowding around farmer incentives for riparian management in Nova Scotia

Incentive programs to encourage landowners to protect habitat should be carefully designed to avoid motivation crowding: basically, replacing intrinsic reasons such as a land ethic with extrinsic ones like payments. Little research on motivation crowding tests real programs, and no such work has been done in Canada. We surveyed farmers in Nova Scotia in 2017 to explore whether participation in a new incentive program called Wood Turtle Strides, or knowledge about a similar incentive program potentially available in the future, would alter reported motivations to use riparian setbacks and buffers. Motivations to use setbacks or buffers were heavily intrinsic across all four survey cohorts: wildlife stewardship and sacrifice motivated actions more than social pressures. We were not able to statistically test for motivational crowding due to low program uptake and thus post-program survey responses, but there was no evidence of second-hand crowding: farmers being motivated by hearing about a program in an adjacent jurisdiction. Findings point to the significance of wildlife stewardship for many farmers, and persistent resistance to conservation among others, as well as a risk of low additionality. More post-program research is necessary to fully understand the program's net impact on motivations and conservation.     

The role of accredited zoos in the recovery process for species at risk in Canada

Zoos and aquariums are responding to the worldwide biodiversity crisis through major conservation initiatives like captive breeding for assurance populations and reintroduction programs. These institutions also fundraise, offer education programs, and provide critical research on biodiversity. Through a case study inside three accredited Canadian zoos, this paper illustrates that zoos and their staff members are being incorporated into many official species‐at‐risk recovery efforts on provincial, federal, and international levels. Specifically, the zoos studied are involved in every stage of the recovery process, from providing valuable research and habitat analyses, to captive breeding animals for reintroduction, to writing recovery strategies and creating recovery policy for multiple jurisdictional levels. Zoo staff indicate that zoos are uniquely suited to conservation because zoos have space, expertise, apolitical status, and the ability to connect with the public. Overall, the paper suggests that zoos can significantly contribute to species‐at‐risk protection and recovery in Canada and beyond.     

The social dynamics of attracting talent in Halifax

The paper reports a case study of factors attracting and retaining talented and creative workers in Halifax, Nova Scotia. All categories of workers interviewed mentioned quality of place and amenities in discussing their location preferences, but that could not fully explain their choices. For some occupations (like health research), talented people followed jobs; in other sectors (like music), talented workers migrated to a sympathetic locale with the right conditions for creative engagement; creative workers in some occupations (like those in architectural, engineering or planning consulting) were more rooted in place. The social dynamics—that is, positive and collaborative social networks within key sectors and a wider community perceived as welcoming and interesting—make this mid‐sized city attractive to talented workers. Local universities and a vibrant music scene generate a mutually reinforcing context that attracted mobile talented and creative workers to the city. Respondents noted Halifax's limited cultural diversity but did not report a perceived lack of tolerance as affecting their choices. In smaller cities, the social dynamics of place and workplace and the quality of life available may play more significant roles than tolerance in attracting and retaining talented workers, challenging a basic assumption of creative cities discourse.     

甘肃省永登县连城鲁土司属寺壁画的科学分析和时代研究

本项研究主要是运用光学显微镜、扫描电子显微镜和共聚焦显微激光拉曼光谱技术,分析了甘肃永登连城鲁土司属寺中的妙因寺、感恩寺和雷坛中的部分壁画。分析结果表明感恩寺和雷坛壁画基本保持了明代最初的绘制风格和内容。其中感恩寺主要壁画的绘画颜料和工艺特点鲜明,表明绘制该壁画的画工不同于绘制鲁土司属寺其他壁画的工匠;妙因寺万岁殿壁画存在后期改动和重绘的情况,其中万岁殿外回廊壁画主要部分的最初绘制时间要早于万岁殿大殿内壁画的最后绘制时间;而妙因寺塔尔殿壁画则绘制于19世纪后期。     

南京报恩寺阿育王塔出土香料溯源研究

2008年南京报恩寺阿育王塔出土了白木香和乳香两种北宋时期香料。本文梳理了南京报恩寺及阿育王塔的历史,通过文献说明了阿育王塔与宋代长干寺圣感舍利宝塔的关系;整理了我国古代典籍中对白木香和乳香的记载,考证出阿育王塔中的白木香乃沉香中的上品,乳香是印度的上品乳香-滴乳;探究了七宝阿育王塔中装藏白木香和乳香的缘由。最后,综合前人对现代白木香和乳香有效化学成分的分析结果,比较了阿育王塔出土白木香和乳香的有效化学成分。
