Abstract

Project Marco Polo provided the opportunity for teachers and students to experience Egypt and the eastern Mediterranean firsthand through the lens of a geographer, archeologist, and oceanographer. The National Geographic Society and U.S. Navy collaborated to provide meaningful applied geography field experiences for teacher and student participants. In addition, participants developed a global perspective which enabled them to better understand the interrelationship of the region's diverse cultures and lands.     

Internationalization of knowledge-intensive SMEs: The case of petroleum-related suppliers

Carlsson, E. & Dale, B. 2011. Internationalization of knowledge-intensive SMEs: The case of petroleum-related suppliers. Norsk Geografisk Tidsskrift–Norwegian Journal of Geography Vol. 65, 191–201. ISSN 0029-1951.

The internationalization of the knowledge-intensive industries, which predominantly consist of SMEs, has received increased attention recently. However, the existing body of theories of internationalization is not adequate for our understanding of multifaceted knowledge-intensive industries. The authors aim to shed light on knowledge-intensive SMEs’ internationalization and thereafter to illuminate recent theories with a relational perspective on firms and discuss their fruitfulness regarding the internationalization of SMEs of this type. Empirical data are drawn from a case study of 10 Norwegian firms, located in Trondheim, that are connected to the petroleum industry through subcontracting technology and services. The study indicates that the firms based their internationalization processes on a complex mix of modes or strategies, none of which were mutually exclusive. Planned strategies as well as coincidental processes and events seem to have influenced the internationalization decisions. It is argued that in order to understand the contingencies that may affect the process of internationalization, the concept of ‘preactivity’ may be a useful addition to the more well-known concepts of ‘reactive’ and ‘proactive’ strategies. Moreover, it is demonstrated that a relational approach is fruitful in order to understand internationalization processes among knowledge-intensive SMEs.     

贵州省赫章福来厂铅锌矿矿床地质特征及找矿前景分析

福来厂铅锌矿产于江子山背斜NE翼,主要沿NW向构造产出,该矿为黔西北地区铅锌矿集区主要矿床之一,赋矿地层主要为石炭系黄龙组(C_2h),岩性为白云岩、白云质灰岩。本文通过对福来厂矿床地质特征的总结及与相邻矿区典型矿床的类比分析,认为该区找矿前景好,深部找矿潜力大,应该加大找矿力度。

Socio-structural forces predicting global water footprint: socio-hydrology and ecologically unequal exchange

ABSTRACT

Growth in water use and threatened shortages of water have become increasingly important in the modern world system. Natural resources are exploited extensively by capitalist interests in industrially advanced nations, while the lower strata of the world system, the underdeveloped societies, are left with limited access to natural resources for their productive processes, particularly water resources. We contribute to socio-hydrological research by examining underlying socio-structural factors that play a part in the process of deteriorating conditions of global water resources. Drawing on a world-systems perspective, this study examines how socio-structural forces – world-system position, per capita beef consumption, per capita energy consumption, and urbanization – affect per capita water footprint, which includes an accounting of “virtual water” consumption. We find that per capita beef consumption and per capita energy consumption have significant positive direct effects, and the world-system position has a significant indirect and total effect on per capita water footprint.

Aerial perspective for shaded relief

ABSTRACT

Aerial perspective is an essential design principle for shaded relief that emphasizes high elevation terrain using strong luminance contrast and low elevations with low contrast. Aerial perspective results in a more expressive shaded relief and helps the reader to understand the structure of a landscape more easily. We introduce a simple yet effective method for adding aerial perspective to shaded relief that is easy to control by the mapmaker.
