Italian Corporate Governance, Investment, and Finance
Italian industrial structure and financial markets have several distinct features. Italian firms are relatively small, few trade publicly and no corporate bond market exists. The limited types of external funds available to Italian firms makes them prone to financing constraints. We examine a panel containing over 1100 Italian firms. We find that firm size does not appear correlated with the severity of financing constraints. We also find that small firms are frequently mature. Our results suggest that young firms face financing constraints, while mature firms may develop relationships with lenders that lower the costs of external funds. Small, young firms appear to face the tightest financing constraints. Many firms are affiliated with pyramidal business groups. We find that affiliation with pyramidal business groups appears to reduce the effect of financing constraints. Our results have important implications for government policy to promote small firm growth in Italy.
The Development of Cultural Competence in Social Work Practice and Education
This research set out to examine the development of cultural competence as a concept, education tool, and practice model in social work. A narrative review was utilized to analyze data collected from articles and primary documents retrieved from scholarly and archival databases. Cultural competence (formerly known as diversity education or practice) was analyzed through a historical and theoretical lens to provide context for its current functioning in social work practice and education today. This research examined social, political, and academic influences on the development and conceptualization of cultural competence as it appears in the National Association of Social Workers and Council on Social Work Education policy statements and standards. The findings indicated that social work has been largely reactionary to external social and political influences in its development of policy and curriculum when it comes to cultural competence. Future research on cultural competence development in social work should focus on social worker\u27s perspectives in engaging with the cultural competence model and a critical examination of its implementation and outcomes
Creating Goals with Adolescent Teenagers
This paper uses James Marcia\u27s Adolescent Identity Development Theory to expand high school juniors and seniors\u27 awareness of the importance of setting goals for themselves. Goals provide accountability, a healthy mindset, and the practice of self-regulation. This project provided juniors and seniors time to reflect and set their goals for their future plans as they embark on a life without the systematic structure the public school has provided

Recent Results from CARMA
The Combined Array for Research in Millimeter-wave Astronomy (CARMA) is a heterogeneous array of 23 telescopes designed to operate in the 1 cm, 3 mm, and 1 mm atmospheric windows. The array is a merger of the eight 3.5 m antennas from the Sunyaev-Zel’dovich Array, the nine 6.1 m antennas from the Berkeley-Illinois-Maryland array, and the six 10.4 m antennas from the Owens Valley Radio Observatory (OVRO). As a signature of Tom Phillips’ legacy, three of the CARMA antennas are from the original 3-element OVRO interferometer built under Tom’s leadership in the early 1980’s. Recent CARMA results are presented on the structure of circumstellar disks and the molecular gas distribution in M 51
Large-Scale Asymmetries in the Transitional Disks of SAO 206462 and SR 21
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations
in the dust continuum (690 GHz, 0.45 mm) and 12CO J=6-5 spectral line emission,
of the transitional disks surrounding the stars SAO 206462 and SR 21. These
ALMA observations resolve the dust-depleted disk cavities and extended gaseous
disks, revealing large-scale asymmetries in the dust emission of both disks. We
modeled these disks structures with a ring and an azimuthal gaussian, where the
azimuthal gaussian is motivated by the steady-state vortex solution from Lyra &
Lin (2013). Compared to recent observations of HD 142527, Oph IRS 48, and LkHa
330, these are low-contrast (< 2) asymmetries. Nevertheless, a ring alone is
not a good fit, and the addition of a vortex prescription describes these data
much better. The asymmetric component encompasses 15% and 28% of the total disk
emission in SAO 206462 and SR 21 respectively, which corresponds to a lower
limit of 2 MJup of material within the asymmetry for both disks. Although the
contrast in the dust asymmetry is low, we find that the turbulent velocity
inside it must be large (~20% of the sound speed) in order to drive these
azimuthally wide and radially narrow vortex-like structures. We obtain
residuals from the ring and vortex fitting that are still significant, tracing
non-axisymmetric emission in both disks. We compared these submillimeter
observations with recently published H-band scattered light observations. For
SR 21 the scattered light emission is distributed quite differently from the
submillimeter continuum emission, while for SAO 206462 the submillimeter
residuals are suggestive of spiral-like structure similar to the near-IR
emission.Comment: ApJL, in press. 6 pages, 3 figures, 2 table
Searching for circumplanetary disks around LkCa 15
We present Karl G. Jansky Very Large Array (VLA) observations of the 7 mm
continuum emission from the disk surrounding the young star LkCa 15. The
observations achieve an angular resolution of 70 mas and spatially resolve the
circumstellar emission on a spatial scale of 9 AU. The continuum emission
traces a dusty annulus of 45 AU in radius that is consistent with the dust
morphology observed at shorter wavelengths. The VLA observations also reveal a
compact source at the center of the disk, possibly due to thermal emission from
hot dust or ionized gas located within a few AU from the central star. No
emission is observed between the star and the dusty ring, and, in particular,
at the position of the candidate protoplanet LkCa 15 b. By comparing the
observations with theoretical models for circumplanetary disk emission, we find
that if LkCa~15~b is a massive planet (>5 M_J) accreting at a rate greater than
1.e-6 M_J yr^{-1}, then its circumplanetary disk is less massive than 0.1 M_J,
or smaller than 0.4 Hill radii. Similar constraints are derived for any
possible circumplanetary disk orbiting within 45 AU from the central star. The
mass estimate are uncertain by at least one order of magnitude due to the
uncertainties on the mass opacity. Future ALMA observations of this system
might be able to detect circumplanetary disks down to a mass of 5.e-4 M_J and
as small as 0.2 AU, providing crucial constraints on the presence of giant
planets in the act of forming around this young star.Comment: Accepted for publication on Ap
Field host range of Apanteles opuntiarum (Hymenoptera: Braconidae) in Argentina, a potential biocontrol agent of Cactoblastis cactorum (Lepidoptera: Pyralidae) in North America
Field exploration in Argentina for cactophagous lepidopteran hosts parasitized by the recently described braconid parasitoid Apanteles opuntiarum MartĂnez & Berta (Hymenoptera: Braconidae) revealed a host range restricted to Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae) and C. doddi. Field collections of cactophagous larvae parasitized by the congeneric and sympatric parasitoid A. alexanderi included the host species C. bucyrus, Sigelgaita nr. chilensis, Tucumania sp., Tucumania tapiacola and Salambona sp. If a narrow host range for A.opuntiarum is confirmed in quarantine with North American cactus-feeding species, then this parasitoid could be released as a biological control agent for C. cactorum with little or no risk to non-target species.Las exploraciones de campo en Argentina de larvas hospedadoras cactĂłfagas parasitadas por Apanteles opuntiarum MartĂnez & Berta (Hymenoptera: Braconidae), un bracĂłnido recientemente descripto, revelaron un espectro de hospedadores restringido a Cactoblastis cacÂtorum (Berg) (Lepidoptera: Pyralidae) y C. doddi. Las colecciones de campo de larvas cactĂłfagas parasitadas por la especie congenĂ©rica y simpátrica A. alexanderi identificaron a C. bucyrus, Sigelgaita nr. chiÂlensis, Tucumania sp., Tucumania tapiacola y Salambona sp. como esÂpecies hospedadoras. Si se confirma en cuarentena el estrecho rango de hospedadores de A. opuntiarum sobre especies norteamericanas que se alimentan de cactus, podrĂa ser liberado como agente de conÂtrol biolĂłgico de C. cactorum, con bajo riesgo o ninguno a especies no blanco.Fil: Varone, Laura.
