State and church in France: regulation and negotiation

In France the distinction between the secular and religious domains is the result of a slow evolutionary process of secularization over a period of two centuries. A key element was the law of separation between churches and State in 1905. Secularization also produced a pluralistic socio-cultural system, which permits an increase in religious supply, issued from outside or inside existent churches. The religious landscape became complex due to the growth of certain groups. Nowadays, efforts to regulate Muslim communities are leading towards a new tendency of state control of religious activities in two fields, namely places of worship and school activities. Religious plurality is recognized by the State in the name of the freedom of beliefs. Private organizations are used for the public practice of religion and easily obtain places of worship. However, this has necessitated a large number of regional or local arrangements. In the name of the freedom of thought, the school system of the Republic is ensured by public schools, or by Catholic or Jewish schools, subject to strict public control. In this matter, there is only minimal tolerance of other denominations.

Involvement Geography: The School Partnership Program In The Junior High School

Abstract

This article presents a family program that extends the materials and meeting times of the Michigan Model Family Geography Challenge, including suggestions on creating a successful family night program. The article focuses on developing positive school-community relationships by inviting local community members to participate in fun academic lessons. In addition to watching the news together nightly, families meet four times during an eight-week period to engage in hands-on geography related activities. One lesson is introduced during each session and families work together to complete assigned tasks. Following the activity, families join together to eat and socialize. The program enhances geographic knowledge (including current events), positive family interactions, and school outreach.     

The interpretation of culture in nature: Landscape transformation and vegetation change during two centuries at Hystad,SW Norway

In Norway, on-site biological surveys precede the designation of nature reserves. Although many nature conservation areas have been affected by past human use (e.g. cattle grazing, timber harvesting), a typical biological survey may fail to portray the extent of human influence on biodiversity and vegetation dynamics. In 1984, Hystad forest (western Norway) was made a nature reserve after botanists interpreted the ecosystem 'close to untouched'. It was thought best to leave the forest alone, so no management plan was developed. It was later realized that the vegetation was changing, but the reason was not obvious. I gathered and analyzed further biological data plus information on land-use history from varied sources (e.g. cadastral maps, archive material and oral histories). The area has undergone a series of transformations since the 17th century. The present forest is no more than 100 years old, and extensive parts are much younger. The initial survey underestimated the extent of cultural impact and failed to predict vegetation change subsequent to reserve establishment, whereas a historical-geographical approach reveals that the vegetation is in a state of transition, driven primarily by a change from active farming to farm abandonment. Planning for conservation must recognize past as well as present human use of the landscape to anticipate consequent land cover responses.     

Preliminary mapping of high-resolution rural population distribution based on imagery from Google Earth: A case study in the Lake Tai basin, eastern China

There is a large rural population in China. Throughout the country, sewage from rural households is mostly discharged with minimal treatment. Knowledge of rural population distribution is essential to study the rural households’ impacts on their surrounding environment. However, high-resolution spatial datasets on rural population distribution are rarely available in China. This study explores the feasibility of using the image from Google Earth to derive a high-resolution map on rural population distribution for a town in the Lake Tai basin of eastern China. Study results show that texture analysis in conjunction with other processing procedures can extract man-made building features from the image reasonably, which can then serve as the basis for the preliminary mapping of rural population distribution in the study region. This may prove to be a promising alternative for deriving spatial datasets on rural population distribution in many parts of the world.     

《金史·地理志》城市行政建制疏漏及补正研究

唐末五代以来,城市行政管理机构发生了重要变化,这就是金代明确出现的具有独立行政职能,但等级规模不同的城市行政管理机构警巡院、录事司和司候司.作为金代与县平行的城市行政管理机构,其官制在《金史·百官志》中具有明确记载,但与县平行的城市行政建置却被《金史·地理志》疏漏,这一问题值得学界研究并加以补正.

Geography in interdisciplinarity: Towards a third conversation

The ‘era of interdisciplinarity’ heralds collaborative inquiry as effective for addressing complex issues at the nexus of disciplinary interests. Geographers have long argued that they are particularly well-suited to contribute to interdisciplinary endeavors because of the breadth and depth that the discipline enfolds. However, within the literature about geography and interdisciplinarity, we find only two rather limiting conversations. The first conversation is concerned with the role(s) and position of geography within academia and focuses on what geographers can do to distinguish themselves while also improving their interactions with scholars from other disciplines. The second conversation largely revolves around how best to conduct interdisciplinarity ‘in the lab and classroom’ and focuses on practical issues associated with making collaborative research operate smoothly for multiple, disciplinary participants. We propose opening up intellectual space for a third conversation about the benefits, challenges and contributions of individual disciplines in interdisciplinary environments. Using survey data, we analyze how geography was perceived by collaborators from various disciplines in an interdisciplinary Urban Ecology program at the University of Washington. We offer this pilot study as a heuristic for others wishing to perform similar small-scale reflexive exercises and advance this “third conversation”.
