Twin Otter - CIRPAS - NPS

A Twin Otter research aircraft has been operated by the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) at the Naval Postgraduate School in Monterey, CA since 1998. The aircraft supports atmospheric and oceanographic research for Office of Naval Research, National Science Foundation, Department of Energy, National Oceanographic and Atmospheric Administration, NASA, and others

Reflections on diversity: Graduate perceptions of campus climate at Dallas Theological Seminary, 1996-2005.

The purpose of this study was to determine how graduates of master's degree programs perceived the ethnic and cultural climate at Dallas Theological Seminary (DTS) during their enrollment there. The population (N=2,223) consisted of graduates of master's degree programs who attended Dallas Seminary from 1996-2005. The study utilized a non-experimental design methodology using a mailed survey questionnaire. A 37.2 % response rate was achieved. Most results were statistically significant at the .05 alpha level utilizing chi-square goodness-of-fit tests

Seasonality in the migration and establishment of H3N2 Influenza lineages with epidemic growth and decline

Background: Influenza A/H3N2 has been circulating in humans since 1968, causing considerable morbidity and mortality. Although H3N2 incidence is highly seasonal, how such seasonality contributes to global phylogeographic migration dynamics has not yet been established. Results: Incorporating seasonally varying migration rates improves the modeling of migration. In our global model, windows of increased immigration map to the seasonal timing of epidemic spread, while windows of increased emigration map to epidemic decline. Seasonal patterns also correlate with the probability that local lineages go extinct and fail to contribute to long term viral evolution, as measured through the trunk of the phylogeny. However, the fraction of the trunk in each community was found to be better determined by its overall human population size Conclusions: Seasonal migration and rapid turnover within regions is sustained by the invasion of 'fertile epidemic grounds' at the end of older epidemics. Thus, the current emphasis on connectivity, including air-travel, should be complemented with a better understanding of the conditions and timing required for successful establishment.Models which account for migration seasonality will improve our understanding of the seasonal drivers of influenza,enhance epidemiological predictions, and ameliorate vaccine updating by identifying strains that not only escape immunity but also have the seasonal opportunity to establish and spread. Further work is also needed on additional conditions that contribute to the persistence and long term evolution of influenza within the human population,such as spatial heterogeneity with respect to climate and seasonalityComment: in BMC Evolutionary Biology 2014, 1

On the presence of giant particles downwind of ships in the marine boundary layer

This study examines large oceangoing ships as a source of giant cloud condensation nuclei (D_p > 2 µm) due to wake and stack emissions off the California coast. Observed particle number concentrations behind 10 ships exceeded those in “control” areas, exhibiting number concentration enhancement ratios (ERs) for minimum threshold diameters of ~2, ~10, and ~20 µm as high as 2.7, 5.5, and 7.5, respectively. ER decreases with increasing downwind distance and altitude. ER becomes better correlated with ship size variables (gross tonnage, length, and beam) as the minimum size threshold increases from 2 to 20 µm, whereas ship speed has a less distinct relationship with ER. One case study of a container ship shows that there are higher concentrations of sea-salt tracer species behind it relative to adjacent control areas. These results have implications for cloud properties and precipitation in marine boundary layers exposed to ship traffic

Enhancing Employability Through a Multi-disciplinary Approach to Graduate Attributes: Embedding Engagement and Developing Self Efficacy in Pre-honours Undergraduates

There is increasing emphasis on the importance of making Graduate Attributes (GAs) explicit to students as part of their degree programme and the role of students themselves in proactively developing GAs (HEA 2015). However, it can be challenging to engage students in non-core activities in large pre-honours classes, and the success of employability activities are also subject to efficacy beliefs and personal qualities (Yorke & Knight, 2007). A further issue is how we embed employability whilst accounting for the specific needs of the subject discipline and linkages with university careers services (O’Leary 2016). The aim of the present project was to work in partnership with careers professionals and students in reflecting on how curricular and extra-curricular activities can develop graduate attributes throughout the degree programme (Daniels & Brooker, 2014). To this end we extended our work with psychology undergraduates (Swingler et al., 2016), by developing and evaluating short-self-reflection in class exercises for pre-honours psychology, earth sciences, and business school undergraduates, which asked students to reflect on their curricular and extra-curricular activities and how the practical skills gained from these activities are linked to graduate attributes. Class activities were followed by discipline specific careers workshops and alumni events, focused on gaining confidence in communicating graduate attributes in an interview context, and the benefits of engaging with alumni on professional networking sites. Our presentation will focus on: 1) students’ levels of self-efficacy in specific GAs across subject disciplines; 2) the relationship of student self efficacy in GAs to self efficacy in H.E.; 3) Student feedback on the in class reflection activities, careers and alumni events, and their intentions to further develop their GAs. The findings will inform participants about the benefits and challenges of embedding GAs and employability in the pre-honours curriculum and include perspectives from students and staff

Where am I now and where do I want to be? Developing awareness of graduate attributes in pre-honours students.

There is increasing emphasis on the importance of making Graduate Attributes (GAs) explicit to students as part of their degree programme and the role of students themselves in proactively developing GAs. The aim of the present project was to encourage students to actively develop and reflect upon curricular and extra-curricular attributes at an earlier stage in their degree programme. To this end we developed and evaluated short-self-reflection exercises in second year (pre-honours) psychology practical classes which asked students to reflect on their curricular and extra-curricular activities and on how the practical skills gained from these activities are linked to graduate attributes.  Activities were followed by careers workshops focused on gaining confidence in communicating graduate attributes in an interview context, and the benefits of engaging with professional networking sites. We evaluated the impact of these activities on: 1) students’ levels of self-efficacy in specific GAs before and after the in-class exercises; 2) students' confidence in presenting their GAs in an interview situation; 3) student awareness of professional networking sites.  The activities resulted in increased self- efficacy ratings after the GAS reflection, increased confidence in presenting their GAs after the careers workshops, and an increased awareness of professional networking sites. The effectiveness of these activities as a method to increase student engagement in developing their GAs will be discussed in the wider context of embedding GAs and employability in pre-honours programmes across STEM disciplines. Keywords: Graduate attributes, employability, self-efficacy, pre-honours, professional networkin
