Dual Supermassive Black Hole Candidates in the AGN and Galaxy Evolution Survey
Dual supermassive black holes (SMBHs) with kiloparsec scale separations in
merger-remnant galaxies are informative tracers of galaxy evolution, but the
avenue for identifying them in large numbers for such studies is not yet clear.
One promising approach is to target spectroscopic signatures of systems where
both SMBHs are fueled as dual active galactic nuclei (AGNs), or where one SMBH
is fueled as an offset AGN. Dual AGNs may produce double-peaked narrow AGN
emission lines, while offset AGNs may produce single-peaked narrow AGN emission
lines with line-of-sight velocity offsets relative to the host galaxy. We
search for such dual and offset systems among 173 Type 2 AGNs at z<0.37 in the
AGN and Galaxy Evolution Survey (AGES), and we find two double-peaked AGNs and
five offset AGN candidates. When we compare these results to a similar search
of the DEEP2 Galaxy Redshift Survey and match the two samples in color,
absolute magnitude, and minimum velocity offset, we find that the fraction of
AGNs that are dual SMBH candidates increases from z=0.25 to z=0.7 by a factor
of ~6 (from 2/70 to 16/91, or 2.9% to 18%). This may be associated with the
rise in the galaxy merger fraction over the same cosmic time. As further
evidence for a link with galaxy mergers, the AGES offset and dual AGN
candidates are tentatively ~3 times more likely than the overall AGN population
to reside in a host galaxy that has a companion galaxy (from 16/173 to 2/7, or
9% to 29%). Follow-up observations of the seven offset and dual AGN candidates
in AGES will definitively distinguish velocity offsets produced by dual SMBHs
from those produced by narrow-line region kinematics, and will help sharpen our
observational approach to detecting dual SMBHs.Comment: 10 pages, 8 figures, accepted for publication in Ap
Psychological resilience of entrepreneurs: A review and agenda for future research
Given that entrepreneurs face substantial adversity in initiating and developing new ventures, a burgeoning stream of research has sought to understand the concept of entrepreneurs’ psychological resilience. To structure and synthesize what we know about entrepreneurs’ psychological resilience, we systematically review the empirical literature to provide insights on how it has been conceptualized and operationalized, along with its key antecedents and outcomes. Based on our review, we advance a promising agenda for future research, grounded in connecting the psychological resilience of entrepreneurs to other research areas connected to the new venture development process. Overall, we point to the urgent need for theoretical precision to enhance the utility of empirical contributions, suggest promising research designs, expand on the important role of adversity, discuss potential boundary conditions, elaborate on the link between entrepreneurs’ psychological resilience and organizational resilience, and address the potential dark side of resilience
Getting the Green: Understanding the Market for Eco-Friendly Tires
The Goodyear Tire and Rubber Company has developed a new tire that replaces petroleum with a more sustainable resource: soybean oil. Following an unexpected surge of popularity in the press, Goodyear decided to look into marketing options for this new tire. For this purpose, the research team is testing market reactions to eco-friendly products, reactions to specific tire names, and potential pricing options for the tire. Previous research indicated multiple areas of concern, including a general skepticism towards “green” terminology, perceptions of low quality in eco-friendly products, and a lack of willingness to purchase eco-friendly products in older generations. The team decided to test the questions and concerns with focus groups and a survey. Results confirmed the skepticism mentioned in earlier research, although the public may be more open to “eco-friendly” terminology than they are to “green” terminology. However, the public is more receptive to sustainable products, although Millennials are not more favorable to these products than Generation X or Baby Boomers are. Assuming that Goodyear can emphasize the increased performance of its new tire, it may be able to charge a premium of 5% to 10%. In addition, brand loyalty to eco-friendly companies may be more important than the environmental friendliness of any particular product. With these thoughts in mind, the team recommends a marketing strategy that emphasizes Goodyear’s overall eco-friendly efforts. Goodyear’s ability to charge a price premium will depend on its selection of a target market, but above all else, authenticity will be essential in its future endeavors
The Politics of the Presidential Medal of Freedom: A Fifty Year Analysis, 1963-2013
Established in 1963, the Presidential Medal of Freedom (PMOF) is the nation’s highest civilian honor. Presidents award the Medal at their discretion to “any person who has made an especially meritorious contribution to (1) the security or national interests of the United States, or (2) world peace, or (3) cultural or other significant public or private endeavors” (Executive Order 11085). Using an original database of all 1963-2013 PMOF recipients, we analyze how presidents exercise this symbolic unilateral power. In particular, we find that Democratic and Republican presidents differ in their recognition of various categories of achievement. Also, presidents have awarded a greater number of PMOFs annually in recent years, and it has become increasingly common to honor a large number of recipients in a single ceremony. While a strategic objective may be to attract positive media attention, our analysis indicates that PMOF ceremonies do not increase presidential approval ratings
On the Move: Employment-Related Geographic Mobility: A Review of Socio-Economic Characteristics in Williams Lake
Labour mobility presents numerous opportunities and challenges for communities in rural and small town settings. Opportunities exist in terms of filling much needed service and worker demands, while also presenting the possibility for community growth and stability by
attracting new residents and businesses. However, the challenges associated with integrating migrant and transient workers into the fabric of community and maintaining consistent service and worker delivery presses the limited capacity available in rural and small town communities.The purpose of this research is to provide an integrative lens through which to view labour - community dynamics within the On the Move: Employment-Related Mobility in the Canadian Context(E-RGM) project in northern BC. The research is premised on a foundation of comparative community/regional research investigating the differences and similarities in preparation for and management of mineral resource activity in two case study
communities/regions: Williams Lake, and Gibraltar mine; and Mackenzie, and the Mt. Milligan mine
Student Perceptions of a Service-Learning Course in a Rural Setting
The primary purpose of this study was to explore students’ perceptions of a servicelearning course at a small, rural, state college. Throughout the semester-long course, the students learned about how to improve afterschool programs and childhood obesity in rural areas similar to the community that encompassed them. The class format consisted of both online discussions over articles, along with in-person meetings. Students then had the option to participate in a paid service opportunity to apply their knowledge in an after-school program; however, no students took part in this component of the class. Reasons the students could not participate in the afterschool program were discussed but most students believed participation would have been beneficial
