Survival of 265 female and 224 male [Formula: see text]1-year-old white-tailed deer (Odocoileus virginianus) marked on 3 study areas in central and northern Illinois was examined. Females lived, on average, 5.5 years and males 2.5 years from birth. Twenty-four of the 265 females lived for at least 10 years from birth, but only 14 males for at least 5 years. The oldest female was 18 years of age and the oldest male 9 years old when killed. For both sexes, deaths were concentrated in the fall, with males more likely to die than females. Males were more likely to die from hunting and females from other causes. Known wounding deaths were 1 for every 3 retrieved deer for archers and 1 for every 8 for firearms hunters. Dispersing male and female yearlings and 2-year-olds suffered greater mortality than did sedentary deer. Annual survival rates of yearling and older females ranged from 0.56 (dispersing 2-year-olds) to 0.92 (8-year-olds). Survival was significantly reduced for 5-year-old females compared with those both older and younger. Annual survival of rates males ranged from 0.35 (dispersing 2-year-olds) to 0.76 (sedentary yearlings).

Psychic distance, as described in the Uppsala internationalization model, is based on the impediments to information flows between a country market and a firm. The greater the impediments, the longer is the distance. The operationalization of psychic distance in empirical investigations is most commonly accomplished through the estimation of perceived "differences" between countries because it is argued that differences account for impediments to knowledge flows. However, this process is highly flawed. This article responds to the many calls for an improvement in the understanding and operationalization of psychic distance. It does so not only by holding to the original definition but also by accounting for wider measures than the differences between the firm's home country and the target country. The author identifies 15 variables from the literature and discusses the relationship between the variables and psychic distance. Using these variables, he constructs an index that measures psychic distance and then applies it to measure distances between 25 country combinations. Finally, he compares the results with actual exporter behavior. A close, negative correlation exists between the psychic distance index and firms' actual selection of export markets.

This paper compares the Uncertainty Avoidance (UA) dimension of national culture across the Hofstede and GLOBE models, looking at relationships in both data and analysis. Rather than mutual support, we detail major differences and anomalies across the studies. We show how these anomalies are resulting in contradictory explanations in research on national differences across a range of individual-, firm-and country-level phenomena. We clarify the UA measurement in both Hofstede and GLOBE, and find that the two models are measuring different components of the UA construct. We propose a two-component model of UA, namely, UA-stress and UA-rule orientation, and confirm its validity with national culture data from the Hofstede and GLOBE studies, and economic data from the World Bank. We also explain the negative GLOBE UA practices-values relationship using motivational theories. A way forward in future UA-related research is suggested. The Hofstede UA index, the GLOBE UA practices scores and the GLOBE UA values scores should be used within the specific domains that they represent: that is, stress, rule orientation practices and rule orientation aspirations, respectively. Resolving the contradictions in UA between and within Hofstede and GLOBE will help cross-cultural researchers develop more robust theories and more practical recommendations for international business management.

The availability of airborne LiDAR data provides a new opportunity to overcome some of the problems associated with traditional, field-based, geomorphological mapping such as restrictions on access and constraints of time or cost. The combination of airborne LiDAR data and GIS technology facilitates the rapid production of geomorphological maps of floodplain environments; however, unfiltered LiDAR data, which include vegetation and buildings, are currently more suitable for geomorphological mapping than data that have been filtered to remove these features. Classification of LiDAR data according to elevation in a GIS enables the user to identify and delineate geomorphological features in a manner similar to field mapping, but it is necessary to use a range of classification intervals in order to map the various types of feature that occur within a single reach. Comparison of a LiDAR-derived geomorphological map with an independently produced field geomorphological map showed a high degree of similarity between the results of the two methods, although ground-truthing is essential in cases where a high degree of accuracy is required. Groundtruthing of a LiDAR-derived geomorphological map showed that around 80% of features mapped using both methods were identified from the LiDAR data, suggesting that the method is suitable for applications such as production of base maps for use in field mapping and selection of sites for detailed investigation.
