Cultural Turn

This paper considers the processes supporting agglomeration in the British television broadcasting industry. It compares and contrasts the insights offered by the cultural turn in geography and more conventionally economic approaches. It finds that culture and institutions are fundamental to the constitution of production and exchange relationships and also that they solve fundamental economic problems of coordinating resources under conditions of uncertainty and limited information. Processes at a range of spatial scales are important, from highly local to global, and conventional economics casts some light on which firms are most active and successful.

Montezuma Quail

Abstract Montezuma quail (Cyrtonyx montezumae) occur throughout the desert mountain ranges in the Trans-Pecos of Texas as well as Arizona, New Mexico, and Mexico. Limited information on life history and ecology of the species is available due to the cryptic nature of the bird. Home range, movements, and preferred habitats have been speculated upon in previous literature with the use of observational or anecdotal data. We used innovative trapping techniques and technologically advanced radio transmitters to assess these ecological parameters for Montezuma quail. The goal of this study was to monitor Montezuma quail to determine home range size, movements, and habitat preference for the Davis Mountains population. We captured a total of 72 birds over the course of two years (2009 – 2010) (36M, 35F, 1 Undetermined). Thirteen individuals with >25 locations/bird were used to estimate the home range, movement, and habitat selection analyses. Home ranges (95% kernel density estimators) averaged 12.83 ha and varied greatly (0.02 – 43.29 ha). Maximum straight-line distances between known locations within home ranges varied from 0.73 – 14.83 km. Distances of movements were greater than previously reported. Preferred habitats consisted of Canyon Mountain Savannah and Foothill Slope Mountain Savannah across three spatial scales. Although our study was able to address some basic ecological attributes of Montezuma quail, additional research is warranted to better understand their population dynamics.

Industrial Organization Theory

This study offers an economic analysis of the television broadcasting industry at the convergence of broadcast and broadband connectivity. It applies the „Structure-Conduct- Performance“(SCP)-paradigm of Industrial Organization theory as framework and investigates how the model can contribute to explaining emergent issues in the economics of Smart TV. It is argued here that SCP model provides a useful heuristic and can fruitfully be applied to various questions surrounding the fundamental transformation of the television broadcasting sector towards Smart TV, notably issues of market structure and competitive behavior. The argument is illustrated by the emerging ecosystem for Smart TV services in Germany. There, the market is still immature and each provider is struggling with the challenge of developing an optimal strategy and organizational form in the Smart TV ecosystem.

Over the past 200 years agriculture has expanded throughout Australia. The culmination of clearing and cultivating land at the farm scale has resulted in highly modified landscapes and a perceived loss of ecosystem services from pest control and pollination. We examine the literature: (i) to identify the appropriate spatial scale for managing pests, natural enemies and pollinators; and (ii) for evidence that farm-scale changes (due to agricultural intensification) across a landscape have resulted in a tipping point favouring pests and hindering pollinators. Although there is limited information to draw firm conclusions, the evidence suggests that actions undertaken on individual farms have an impact both on their neighbours and regionally, and that the culmination of these actions can lead to changes in population dynamics of pests, natural enemies and pollinators. For major pest species, there is reasonable evidence that grain growers may benefit from improved management and higher yields by implementing area-wide pest management strategies on a landscape scale in collaboration with growers of other crops that also share these pests. As yet, for natural enemies and pollinators there is little direct evidence that similar area-wide initiatives will have a greater effect than management strategies aimed at the field and farm level. Managing pests, natural enemies and pollinators beyond the scale of the field or farm is technically and socially challenging and will required a well defined research agenda, as well as compromise, balance and trading among stakeholders. We highlight critical knowledge gaps and suggest approaches for designing and managing landscapes for ecosystem services.

Abstract Spatial agglomeration phenomena on the earth's surface permeate in various fields of the natural and human world, yet their researches in human society are relatively few with the focus mainly on the economic concept of "industrial clusters". Precise quantitative descriptions, in-depth logical analyses and overall systematic explanations are lacked in various intra-urban spatial agglomeration phenomena. Using over 10 million POIs in the mainland China, 18 grid network models of 9 grid scales based on two kinds of spatial relationships (co-location/adjacent) are constructed in this article. 23 typical place communities are extracted based on complex network analysis, and four types including 11 sub-categories of agglomeration patterns are summarized. Drawing on the concept of "ecological niche", we further propose the theory of "place niche" and analyze the logic and structure of intra-urban place communities within its framework. This study extends the spatial scales and dominating factors of the agglomeration phenomenon research.
