Spoken vernacular dialects of Aramaic, generally known as Neo-Aramaic dialects, have survived down to modern times in various regions of the Middle East and can be divided into various subgroups. There are some islands of Neo-Aramaic in the West of Iran, which are situated on the eastern periphery of the Neo-Aramaic area. These include dialects spoken by Christians and Jews belonging to the North-Eastern Neo-Aramaic subgroup in the West Azerbaijan, Kordestan and Kermanshah provinces and Neo-Mandaic spoken by Mandaeans in the Khuzestan province. This paper examines a number of distinctive features of the Neo-Aramaic dialects of Iran, including those that have been induced by contact with other languages in the area. 相似文献

Climatic signal in tree-ring chronologies of Cedrus deodara from Chitral Hindukush Range of Pakistan
Tree-rings are an important tool for the investigation of paleoclimatic records for regions or periods of time with no instrumental climatic data. However, the responses of different species and sites to various climatic parameters are unusual. In the present study, we developed tree-ring-width chronologies of Cedrus deodara from three different sites of Chitral Hindukush range of Pakistan. The study was conducted to understand tree-growth climate relationship and its applicability in proxy climate investigations. The chronologies covered the past 469 to 595 years, with a mean segment length (MSL) ranging from 148 to 223 years. Climatic data obtained from the three weather stations showed strong correlation and was found useful for tree-ring climate relationships. Correlation Function (CF) and Response Function (RF) analysis showed that spring precipitation (March–May) is a critical limiting factor for tree-ring growth, and temperature prior to November may also play a major role in affecting tree ring-growth. The results exposed that the three sites have continuous relationship indicated that only single species from different locations are affected by the same environmental variables and hence can be used in climate reconstruction in combination. The Cedrus deodara chronologies developed at different locations had several corresponding narrow and wide marker rings indicating a large macroclimatic response to regional climatic conditions. The current study suggests that the tree-rings of Cedrus deodara from the Chitral Hindukush range could be used to develop chronologies for the reconstruction of seasonal climatic variables. 相似文献

Citizen and government co-production of data: Analyzing the challenges to government adoption of VGI
With the recent rise of open government and open data initiatives, governments are increasingly adopting new approaches of citizen participation to support a more democratic, transparent, and inclusive government system. Among other forms of citizen participation, Volunteered Geographic Information (VGI) is one approach to connecting citizens and government. Accepting VGI as a way to update government data or collect near-real-time information from citizens can create a partner-like relationship where citizens voluntarily contribute time and effort to support government actions. However, as a relatively new approach to citizen participation and data collection, VGI requires evaluation from the perspective of governments. This research investigates the challenges and opportunities that governments have found through the implementation of VGI projects. Results are drawn from interviews conducted with 19 government organizations, revealing organizational and technical challenges that limit the adoption of VGI. Organizational challenges are associated with government mindset, implementation, and project management, while technical challenges involve development of the system and quality of data. Given these challenges, we derive recommendations within the phases of project initiation, implementation, and expansion that can foster VGI adoption in government. 相似文献
