Student Perceptions Of And Preferences For A Short Overseas Study Tour
Business programs and colleges of business have responded to calls from both AACSB and industry with many different methods of internationalizing business curricula. One increasingly popular method of exposing business students to international issues is the short study tour. This research investigates student perceptions of and preference for, different aspects of a short study tour. Students at a medium-sized metropolitan university in the Midwest were asked to complete a survey. Results suggest that for the students involved in this research, cost is the most important criteria, followed by the country or countries in which the tour will take place. Students recognize the value of short study tours, and seem prepared to pay a reasonable price for the appropriate experience. The paper concludes with a discussion of the value of study tours to developed versus emerging market countries

Use of the cell cycle progression (CCP) score for predicting systemic disease and response to radiation of biochemical recurrence
BACKGROUND:
Determining the optimal treatment for biochemical recurrence (BCR) after radical prostatectomy (RP) is challenging.
OBJECTIVE:
We evaluated the ability of CCP score (a prognostic RNA expression signature) to discriminate between systemic disease and local recurrence in patients with BCR after RP.
METHODS:
Sixty patients with BCR after RP were selected for analysis based on: 1) metastatic disease, 2) non-response to salvage external beam radiotherapy (EBRT), and 3) durable response to salvage EBRT. CCP scores were generated from the RNA expression of 46 genes. Logistic regression assessed the association between CCP score and patient group.
RESULTS:
Passing CCP scores were generated for 47 patients with complete clinical and pathologic data. CCP score predicted clinical status when comparing patients with metastatic disease or non-responders to salvage therapy to patients with durable response (p = 0.006). CCP score remained significantly predictive of clinical status after accounting for time to BCR, PSA level at BCR, and Gleason score (p = 0.0031).
CONCLUSIONS:
Elevated CCP score was associated with increased risk of systemic disease, indicating that CCP score may be useful in identifying patients with BCR who are most likely to benefit from salvage radiation therapy
Quantifying full phenological event distributions reveals simultaneous advances, temporal stability and delays in spring and autumn migration timing in long-distance migratory birds
Acknowledgements We thank all Fair Isle Bird Observatory staff and volunteers for help with data collection and acknowledge the foresight of George Waterston and Ken Williamson in instigating the observatory and census methodology. We thank all current and previous directors of Fair Isle Bird Observatory Trust for their contributions, particularly Dave Okill and Mike Wood for their stalwart support for the long-term data collection and for the current analyses. Dawn Balmer and Ian Newton provided helpful guidance on manuscript drafts. We thank Ally Phillimore and two anonymous referees for helpful comments. This study would have been impossible without the Fair Isle community's invaluable support and patience over many decades, which is very gratefully acknowledged. WTSM and JMR designed and undertook analyses, wrote the paper and contributed to data collection and compilation, MB contributed to analysis and editing, all other authors oversaw and undertook data collection and compilation and contributed to editing.Peer reviewedPostprin

The GALAH survey: Properties of the Galactic disc(s) in the solar neighbourhood
Using data from the GALAH pilot survey, we determine properties of the Galactic thin and thick discs near the solar neighbourhood. The data cover a small range of Galactocentric radius (7.9 RGC 9.5 kpc), but extend up to 4 kpc in height from the Galactic plane, and several kpc in the direction of Galactic anti-rotation (at longitude 260◦ ≤ ≤ 280◦). This allows us to reliably measure the vertical density and abundance profiles of the chemically and
kinematically defined ‘thick’ and ‘thin’ discs of the Galaxy. The thin disc (low-α population) exhibits a steep negative vertical metallicity gradient, at d[M/H]/dz = −0.18 ± 0.01 dex kpc−1, which is broadly consistent with previous studies. In contrast, its vertical α-abundance profile is almost flat, with a gradient of d[α/M]/dz = 0.008 ± 0.002 dex kpc−1. The steep vertical metallicity gradient of the low-α population is in agreement with models where radial
migration has a major role in the evolution of the thin disc. The thick disc (high-α population) has a weaker vertical metallicity gradient d[M/H]/dz = −0.058 ± 0.003 dex kpc−1. The αabundance of the thick disc is nearly constant with height, d[α/M]/dz = 0.007 ± 0.002 dex kpc−1. The negative gradient in metallicity and the small gradient in [α/M] indicate that the high-α population experienced a settling phase, but also formed prior to the onset of major
Type Ia supernova enrichment. We explore the implications of the distinct α-enrichments and narrow [α/M] range of the sub-populations in the context of thick disc formation.LD and MA acknowledge funding from the Australian Government through ARC Laureate Fellowship FL110100012.
