Radio labeling is derived from the assignment of radio frequencies (channels) to a set of transmitters. The frequencies assigned depend on the geographical distance between the transmitters: the closer two transmitters are, the greater the potential for interference between their signals. Thus when the distance between two transmitters is small, the difference in the frequencies assigned must b...

Agrobiont spider species are well adapted to arable systems, which have fairly uniform vegetation structure and pest assemblages over continent-wide areas. We wanted to study, whether agrobiont spider subassemblages and the life history of the most prominent agrobiont, Pardosa agrestis, show any regional variation within Hungary, where only modest climatic differences exist between the NW and S...

Identifying environmental factors that structure intraspecific genetic diversity is of interest for both habitat preservation and biodiversity conservation. Recent advances in statistical and geographical genetics make it possible to investigate how environmental factors affect geographic organisation and population structure of molecular genetic diversity within species. Here we present a stud...

In this paper, an integrative conceptual model of internal and external factors influencing the success of global software development (GSD) projects is proposed. Its intention is to provide a holistic view on factors contributing to success in GSD projects as discussed in the literature. Four external factors (cultural differences, language differences, geographical distance, and time zone dif...

The mStar environment for distributed education utilizes the WWW and IP-multicast to enable teacher-student collaboration over large geographic distances. Several educational projects, spanning from secondary school courses to in-house training in companies, have deployed the mStar environment. This paper reports on experiences gained over a year of practice at Luleå University of Technology an...

This paper presents a framework for analysing the role of regional headquarters in the globalisation strategies of transnational corporations (TNCs). Drawing upon a theoretical gap in existing urban studies and international business literature, we argue that the triadisation and regionalisation of TNC activities increase the demand for control and co-ordination functions previously performed b...

As Global Virtual Teams (GVTs) operate across diverse geographies, time-zones, and cultures, they present particular problems for project management in that their characteristics may negatively affect team performance. While a significant body of research exists on project management and GVTs, previous studies have not fully elaborated on the collective impact that GVT characteristics, such as ...

Existing studies have often failed to find positive impacts of horizontal FDI on domestic firms. We argue that the two effects underpinning the impacts of horizontal FDI (i.e., the positive spillover effect and the negative competition effect) have different degrees of attenuation with geographic distance. As FDI is often distributed unevenly across space, studies that do not account for the ge...

We numerically investigate the epidemic spread phenomena and efficient immunization strategies on complex networks embedded in geometry. It is assumed that there exists an unavoidable time delay (we call it the detection time) between the actual infection and the beginning of immunization, and we implement two different immunization strategies: one is based on topological connection neighbors (...

The value of using otolith chemistry to characterize recruitment in terms of natal source regions depends on how consistently spatio-temporal variation can be resolved. The objective of this study was to compare regional classification patterns in the otolith chemistry of juvenile Spotted Seatrout (Cynoscion nebulosus) between two years experiencing disparate hydrological regimes, and separated...
