The Geotechnical Engineering Office of Hong Kong database of landslides for the period 1984-1993, containing over 3000 landslide records, and data for major landslides before this period were made available for a landslide risk assessment study. Data from over 1100 of these landslides in man-modified slopes were collated, processed, and analyzed statistically. Multiple regression models, based on slope geometry, were developed for the prediction of landslide travel on a horizontal surface below the slope. Although developed for slopes in Hong Kong, the models can be applied in similar geological situations (weathered granite and other weathered volcanics) and are suited for landslide risk zoning in areas below man-modified slopes and for the assessment of risks from individual cuts and fills.Key words: landslide, travel distance, risk, risk assessment.

Abstract The objective was to determine effect of trucking distance on sale price of beef calf and feeder cattle lots sold through Superior Livestock Video Auctions from 2010 through 2018. Data analyzed were collected from 211 livestock video auctions. There were 42,043 beef calf lots and 19,680 feeder cattle lots used in these analyses. Six states (Colorado, Iowa, Kansas, Nebraska, Oklahoma, and Texas) of delivery comprised 70% of calf lots and 83% of feeder cattle lots and were used in these analyses. All lot characteristics that could be accurately quantified or categorized were used to develop multiple regression models that evaluated effects of independent factors using backwards selection. A value of P < 0.05 was used to maintain a factor in the final models. Based upon reported state of origin and state of delivery, lots were categorized into one of the following trucking distance categories: 1) Within-State, 2) Short-Haul, 3) Medium-Haul, and 4) Long-Haul. Average weight and number of calves in lots analyzed was 259.2 ± 38.4 kg BW and 100.6 ± 74.3 head, respectively. Average weight and number of feeder cattle in lots analyzed was 358.4 ± 34.3 kg BW and 110.6 ± 104.1 head, respectively. Beef calf lots hauled Within-State sold for more ($169.24/45.36 kg; P < 0.0001) than other trucking distance categories (Table 1). Long-Haul calf lots sold for the lowest (P < 0.0001) price ($166.70/45.36 kg). Within-State and Short-Haul feeder cattle lots sold for the greatest (P < 0.0001) price ($149.96 and $149.81/45.36 kg, respectively; Table 2). Long-Haul feeder cattle lots sold for the lowest (P < 0.0001) price, $148.43/45.36 kg. These results indicate there is a price advantage for lots expected to be hauled shorter distances, likely because of cost and risk associated with transportation.

Landslide Risk Assessment

Landslides are unavoidably linked to forestry operations in coastal BC. A neglected component of landslide risk assessment is the degree to which impacts from landslides may be acceptable. One hundred and thirteen professionals in the BC forest industry, including foresters, biologists, geoscientists and engineers, examined landslide tolerability criteria. Despite differences by sector, there was general agreement that landslides resultant of ignoring expert advice or where an expert was clearly at fault were unacceptable, and penalties were high. In more ambiguous cases, increased consequences resulted in increased scrutiny and it was clear that experts should expect to be held responsible for their decisions by government officiators and the public. Key words: landslide, risk, risk perception, acceptable risk, landslides and forestry
