"It Was Fine, if You Wanted to Leave": Educational Ambivalence in a Nova Scotian Coastal Community 1963–1998

This article reports on a study of schooling in southwest Nova Scotia. Using Bourdieu's concepts of cultural capital and habitus, I analyze rural men's relationships involving identity, work, place, and schooling to explain continuing high male dropout rates and local traditions of ambivalence and resistance to schooling. I conclude that the tension between formal schooling and place is endemic in many rural communities and that qualitative migration analysis can reveal the complexity of relationships between learning and leaving.     

Do borderline nuclear changes in gynaecological cytlogy constitute a reliable reporting category?

Fourteen laboratories participated in a national slide exchange study to investigate whether borderline nuclear changes (BNC) constitute a reliable reporting category. Slides were submitted by participating laboratories, having achieved a 100% intralaboratory consensus at the primary screener, checker, and medical levels. Sets of seven slides were examined in laboratories for 1 week, and exchanges were undertaken over a 6-month period. Each laboratory was requested to submit three consensus opinions on each slide at the primary screener, checker, and medical levels.
Response patterns for submitted slides achieving a reporting category consensus at the 50 and 80% consensus levels indicated that negative, BNC, and mild dyskaryosis are distinct and comparable categories. Similarly, the two subcategories of BNC with or without human papillomavirus (HPV) are nearly as distinct as the overall BNC category.
The percentage of submitted slides achieving consensus at consensus levels between 50 and 80% produced variable findings with regard to the practical success of the main reporting categories. The negative category was reasonably successful, whereas mild dyskaryosis was consistently poor. Borderline nuclear changes were successful at the 50% consensus level but showed a rapid decline by the 65% consensus level. The reason(s) for this remains speculative but indicates a possible potential of BNC to work successfully with additional training and education.
Reporting practices were not consistent among the laboratories and differences were identified between medical and nonmedical staff. A high use of the BNC category was noted in slides that failed to achieve consensus. A national study assessing all grades of abnormalities would appear essential.     

Training in zoo biology,captive breeding,and conservation

Different types of training in zoo biology, captive breeding, and conservation are discussed and the availability of a variety of programs documented. Emphasis is given to the need for more training in general, and especially for less-developed countries where zoos have much potential yet to be realized. The aims, structure, content, and impact of the Jersey Wildlife Preservation Trust's International Training Program are examined.     

京津冀城市群区域产业协同的政策格局及评价

产业协同发展是京津冀区域协同发展的三个重点领域之一,科学合理的产业协同政策是加快实现这一发展目标的重要保障。通过对京津冀城市群区域产业协同政策事件的系统梳理,从区域、省际和城际3个尺度解读了产业协同政策的格局及其演进过程,并从新区域主义的管治视角进行了评价。研究认为:(1)京津冀产业协同发展进入了快速发展的机遇期,协同政策极大地推动了区域内跨地产业合作和城市间产业联系,有助于提高城市群整体竞争力;(2)不同空间尺度的产业协同政策关注的重点、发展的方向、演化的特征不同,当前城市间的产业协同政策与区域协同发展目标的关系不明确,产业协同对生态环境的改善尚不显著,亟需加强研究和统筹协调;(3)受城市行政区等级关系和竞争关系的影响,京津冀产业协同政策与市场调节无法实现高度契合统一,与新区域主义的管治理念并不相符,影响科学合理协同政策的制定与实施。研究对当前京津冀区域产业协同发展推进及其政策制定有重要的参考意义。     

Extended Producer Responsibility in Thailand

Waste electrical and electronic equipment (WEEE) sheds light on the dimmer side of production and consumption patterns in modern societies. The rapid increase in its quantity and complexity contribute to the challenges it poses to solid waste management systems. Several members of the Organisation for Economic Co‐operation and Development (OECD) have relied on the principle of extended producer responsibility (EPR) to tackle the issue, with varying degrees of success. Several non‐OECD countries, including Thailand, are now developing WEEE programs and are looking for lessons from these first movers. This case study aims to provide an understanding both of this context and of the EPR program for WEEE proposed for Thailand. It finds that EPR mechanisms in general, and the proposed buy‐back system financed by product fees in Thailand in particular, have a strong potential to consolidate WEEE collection for the formal recycling sector by offering end users monetary incentives. On the negative side, this is an expensive combination of policy instruments, and the institutional design of the governmental fund is rigid. The policy proposal also contains no mechanism for product redesign—one of the objectives in the national WEEE strategy. This article suggests that the effectiveness of the policy might benefit from more flexibility at the compliance scheme level, in order to lessen the monopoly of the governmental fund, as well as the introduction of differentiated fees to promote environmentally friendly products.     

Charging up Battery Recycling Policies: Extended Producer Responsibility for Single‐Use Batteries in the European Union,Canada, and the United States

Extended producer responsibility (EPR) policies have proven effective at raising consumer awareness, expanding waste collection infrastructure, and shifting costs of end‐of‐life (EOL) management from municipalities to stewardship organizations. Yet, such policies have been less successful in advancing waste management programs that ensure a net environmental benefit. This article analyzes how EPR policies for single‐use batteries in the European Union (EU), Canada, and the United States address the environmental costs and benefits of EOL management. Considering these EPR policies is instructive, because single‐use batteries have high collection costs and are of relatively low economic value for waste processors. Without deliberate planning, the environmental burdens of collecting and recycling such batteries may exceed the benefits. This article considers how EPR policies for single‐use batteries integrate performance requirements such as collection rates, recycling efficiencies, and best available techniques. It argues that for such policies to be effective, they need to be extended to address waste collection practices, the life cycle consequences of EOL management, and the quality of recovered materials. Such strategies are relevant to EPR policies for other products with marginal secondary value, including some textiles, plastics, and other types of electronic waste.

The differentiation of bacterial isolates encountered in fieldwork

A numerical value for each isolate is obtained by adding the appropriate value for each positive test given by each organism.

The advantages and disadvantages of the method compared with more conventional methods of bacterial identification are discussed and some modifications or improvements are suggested. This simplified approach is presented as being suitable for obtaining information about the diversity of bacterial types on student fieldwork.     

A-Level ‘Questions’ in Biology—The Nature of the Influence

The purpose of keeping animals in schools and the main problems encountered in their maintenance are summarised. Many teachers prefer animals which are kept typically in research laboratories over animals which can be collected from the student's environment. However, small animals of economic importance can combine some of the advantages of both of these groups of animals. Chickens, bees, plant pests and their natural enemies have been tried out in the Agriculture as Environmental Science Curriculum Project and can be used for observation and measurement as well as to stress the aspect of relevance to real life problems. In their maintenance, standard equipment and methods can often be used and help the teacher to solve some of the main problems of keeping animals.

Two curriculum units, on a fruit fly and on honey bees, are described. Reasons for a widespread negative image of rural studies are discussed, and positive, effective outcomes, reported in the evaluation of an environmental science course, are used to substantiate the advantages of keeping animals of economic importance in schools.
