Through Student Eyes: Perceptions and Aspirations of Students from the Armenian State Agrarian University and Selected European Universities

Abstract This research compared attributes of students enrolled in the Armenian State Agrarian University (ASAU) with university students from 30 European countries (EFMD) about graduate study policy issues. A cross-national comparative design used a survey questionnaire to explore contextual, social and cultural phenomena. Samples included 801 ASAU and 3,265 EFMD students. Demographics of samples were similar. Students were largely unaware of the Bologna reforms and the impact on study abroad. Slightly more than half of EFMD participants were in a bachelors programme compared to 96% of ASAU students. ASAU students held a more pragmatic rationale for foreign study, ranking ‘advancing professional careers’ as the top reason, while EFMD students chose ‘overall experience’. Obstacles included bureaucracy, funding and accommodations. Although groups had similar geographical preferences for foreign study, Eastern Europe was more preferred by ASAU students. Half of the EFMD students planned graduate enrollment ‘immediately following the degree’ compared to one-quarter of ASAU students. Half of the EFMD students were aware of mobility scholarships compared to three-quarters of ASAU students. One in two EFMD students reported university media rankings important compared to one in seven ASAU students. The Bologna Declaration accelerated horizontal collaboration among European universities. Students have a larger collective voice in curriculum change. The findings of this research provide a better understanding of student aspirations, motivations, expectations and barriers. These findings can contribute to guiding policies and procedures for recruitment, admission, retention and mobility.

Evaluating Hybrid Bermudagrass Using Spectral Reflectance under Different Mowing Heights and Trinexapac-ethyl Applications

Quantitative spectral reflectance data have the potential to improve the evaluation of turfgrasses in variety trials when management practices are factors in the testing of turf aesthetics and functionality. However, the practical application of this methodology has not been well developed. The objectives of this research were 1) to establish a relationship between spectral reflectance and turfgrass quality (TQ) and percent green cover (PGC) using selected reference plots; 2) to compare aesthetic performance (TQ, PGC, and vegetation indices) and functional performance (surface firmness); and 3) to evaluate lignin content as an alternate means to predict surface firmness in turfgrass variety trials of hybrid bermudagrass [Cynodon dactylon ·C. transvaalensis]. A field study was conducted on mature stands of three varieties (‘TifTuf’, ‘TifSport’, and ‘Tifway’) and two experimental lines (04-47 and 04-76) at two mowing heights (0.5 and 1.5 inch) and trinexapac-ethyl application (0.15 kg ha and nontreated control) treatments. Aesthetic performance was estimated by vegetation indices, spectral reflectance, visual TQ, and PGC. The functional performance of each variety/line was measured through surface firmness and fiber analysis. Regression analyses were similar when using only reference plots or all the plots to determine the relationship between individual aesthetic characteristics. Experimental line 04-47 had lower density in Apr. 2010, whereas varieties ‘TifTuf’, ‘TifSport’, and ‘Tifway’ were in the top statistical group for aesthetic performance when differences were found. ‘TifSport’ and ‘Tifway’ produced the firmest surfaces, followed by ‘TifTuf’, and finally 04-76 and 04-47,which provided the least firm surface. Results of leaf fiber analysis were not correlated with turf surface firmness. This study indicates that incorporating quantitative measures of spectral reflectance could reduce time and improve precision of data collection as long as reference plots with adequate range of green cover are present in the trials.
