Do motorways shape urban growth? Analysis of growth patterns with micro-level data – before and after road openings in two Danish motorway corridors
The paper is an offspring from the Research project Town, Road and Landscape that aims to assess the effect of the Danish motorway network (specifically the last 20 years) on urban growth and interaction patterns. As one of the main interests of the project is the changing urban form and the changing character of the roadscape, the impact of the motorway is in part analysed with micro level data, spatial statistics and GIS – to allowing mapping of changing development trends in motorway corridors. The paper presents analysis of the impact of motorway openings on urban form in two Danish motorway corridors. The analysis is based on a before and after perspective – where the building activity and its location (building register with address coordinates) after the opening of the motorway is compared to building activity in the years before the construction of the motorway. Preliminary results suggest that the motorway most markedly influences the location of non-residential building activities within the city – in favour of locations near the entrance points to/from the motorway network. The development can be explained in part by municipal planning, which in some instances has opened up the new locations for development far ahead of market demand – and in part by an increasing demand for exposed and accessible sites for business development which still seems to be in its beginning.

Transient repression of the synthesis of OmpF and aspartate transcarbamoylase in Escherichia K12 as a response to pollutant stress
The synthesis of total cellular proteins in Escherichia coli K12 was studied in batch culture following exposure of cells to low concentrations of monochlorophenol, pentachlorophenol and cadmium chloride. Changes in protein patterns were identified after pulse-chase labelling of proteins with [35S]methionine and subsequent two-dimensional gel electrophoresis (2D-PAGE). We demonstrated that besides the induction of some stress proteins, also a transient decrease in the rate of synthesis of other proteins occurred. Two of these proteins were identified as OmpF and aspartate transcarbamoylase (ATCase). Their transient repression appeared to be a general response to stress elicited by different pollutants and may therefore be used as a general and sensitive early warning system for pollutant stress
Effectiveness of Online Videos to Modify Students\u27 Knowledge and Perceived Barriers Regarding Study Abroad Opportunties
The need to increase the number of students participating in study abroad is a goal that higher education must recognize. For ten years, the level of participation among students enrolled in colleges of agricultural sciences has remained at constant level. In a society that is globally interconnected, it is imperative that future graduates comprehend various dimensions of culture, agricultural production, and economy to succeed. The purpose of this study was to determine the effectiveness of online videos to modify students’ knowledge and perceived barriers regarding study abroad opportunities. The objectives of this paper are: 1. Describe the amount of learning obtained through watching study abroad videos; 2. Determine changes to students’ perceived barriers regarding their possible participation in study abroad programs. In order to assess students’ perceptions, three online videos were developed. Videos were based on a semester-long study abroad program in Russia and two study tour programs in Puerto Rico and Brazil, respectively. A quasi-experimental research design was used in this study. One hundred fifty six students from nine sections of the first year seminar participated in the study. In this study, the use of online videos was effective in communicating information and diminishing the perceived barriers to study abroad. Other colleges and programs could use this strategy to promote their international programs. In addition, administrators could use the results of this study to develop online videos to teach content and dispel myths regarding study abroad programs
