according to webster and wind (1972) and anderson et al (1987), “organizational buying is a complex process and involves many people from different functional areas, multiple goals and potentially conflicting decision criteria. moreover, the customers of today are also more knowledgeable and selective when making their purchasing decisions. since a key to organizational survival is the retentio...
Identifying herbaceous species and their composition at forest road edges and skid trails is an urgent task to prevent changes of natural and native composition of species and invasion of exotic species. The present study aimed to evaluate the herbaceous species cover grown on the forest road surface, cut and fill slopes and skid trail surface and their comparison with inside forest in order to...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Purpose: In rural areas of developing countries, lack of facilities and geographical isolation can be considered as the major causes of poverty leading to limited opportunities in achieving sustainable economic and social improvement. Public transport system has a crucial role in the prevention of social and economic exclusion and marginalization of rural and remote areas. Access to public tran...
forest roads are basic infrastructures for management of forested areas. sustainable management of roads depends on regular and timely forest road maintenance. road inventory is as an important tool to recognize the needs of roads and do corresponding correction operations. gis can be a powerful tool for acquirement, analysis and management of data in road management. the purpose of this study ...
The sustainable management of forest resources can only be achieved through a well-organized road network designed with the optimal spatial planning and the minimum environmental impacts. This paper describes the spatial layout mapping for the optimal forest road network and the environmental impacts evaluation that are caused to the natural environment based on the multicriteria evaluation (MC...
abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...
forests are an important economic source for human and have key role in nutrient cycle, hydrology and ecosystem performance, any interference in this vital ecosystem causes to damage to forests. mechanical logging and road construction in forest areas have led to much soil compaction. soil physical and chemical properties were studied in parts of road and non-road in the darabkola forest of ira...
