Systemic risk determinants in the European banking industry during financial crises, 2006-2012
The recent financial turmoil has stimulated a rich debate in banking and financial literature on the identification of systemic risk determinants and devices to forecast and prevent crises. This paper explores the contribution of corporate variables to systemic risk using the CoVaR approach (Adrian and Brunnermeier, 2016). Using balanced panel data on 141 European banks from 24 countries, which were listed from 2006Q1 to 2012Q4, we investigated the impact of corporate variables during the three regimes that characterised the European banking sector-the subprime crisis (2007Q3-2008Q3), the European Great Financial Depression (2008Q4-2010Q2), and the sovereign debt crisis (2010Q3-2012Q4). Our results show that size did not play a significant role in spreading systemic risk, while maturity mismatch did. However, the nature and intensity of these two determinants varied across the three regimes
Collaborative Instruction for Information Retrieval and Appraisal Skills in Evidence-Based Practice Models for Dental Hygiene Students.
Objectives:
1. Collaborate with VCU Dental Hygiene Program faculty to develop and evaluate a model of evidence-based practice (EBP) for students in didactic and clinical settings.
2. Describe how a course was modified to emphasize evidence-based practice.
3. Analyze course evaluations and student scholarly output.
Methods/Materials:
Dental educators strive to develop graduates who practice evidence-based practice and whose clinical decisions are based on current scientific research. A medical librarian was invited to assist in integrating EBP into the dentistry curriculum in 2012. To gain a better understanding of EBP in dental settings, the librarian and dental hygiene faculty attended the Forsyth ADA Evidence-Based Dentistry training in Boston, Massachusetts that same year. The collaborators revised a course to take students through the mechanics of EBP, including demonstrating transfer into the clinic setting and developing a model of real-time information retrieval useful after graduation in the âreal world.â
Results:
In didactic activities, students received instruction on information retrieval as well as critical appraisal skills to answer clinical questions, reinforcing the EBP model. This culminated in students creating improved literature reviews for capstone projects, posters and table clinic presentations, stronger clinical information retrieval skills, and increased publications in refereed professional journals. Interaction between students, the librarian and faculty resulted in positive outcomes in EBP concepts used for generation of decision making in clinic as well as peer presentations in local, regional and national settings.
Conclusions:
The collaborative effort was valuable as it strengthened the relationship between dental hygiene faculty, students and the librarian. Additionally, studentsâ experience was enhanced as they practiced retrieval strategies and critical appraisal of research literature. This enabled them to develop as âconsumersâ of current professional research literature, model evidence-based practice and publish their writing in professional journals
Ethical judgment and radical business changes: the role of entrepreneurial perspicacity
This study examines the implications of practical reason for entrepreneurial activities. Our study is based on Thomas Aquinasâ interpretation of such virtue, with a particular focus on the partition of practical reason in potential parts such as synesis, or common sense, and gnome, or perspicacity. Since entrepreneurial acts and actions deal with extremely uncertain situations, we argue that only this perspicacity, as the ability of correctly judging in exceptional cases, has the power to find wisdom under such blurred conditions. Perspicacity frees entrepreneurs from their cognitive schemata rendering them able to be truly entrepreneurial. Based on this vision and thanks to a semantic analysis of the meaning of the Greek word gnome, we construct an interpretative model for entrepreneurial judgment composed of three dimensions, specifically, knowledge-cognitive, external-affective and personal-reflective. The model highlights how a âsuccessfulâ entrepreneurial judgment is also such from a holistic point of view
On the (2,3)-generation of the finite symplectic groups
This paper is a new important step towards the complete classification of the
finite simple groups which are -generated. In fact, we prove that the
symplectic groups are -generated for all . Because
of the existing literature, this result implies that the groups
are -generated for all , with the exception of and
More on regular subgroups of the affine group
This paper is a new contribution to the study of regular subgroups of the
affine group , for any field . In particular we associate to any
partition of abelian regular subgroups in such a
way that different partitions define non-conjugate subgroups. Moreover, we
classify the regular subgroups of certain natural types for . Our
classification is equivalent to the classification of split local algebras of
dimension over . Our methods, based on classical results of linear
algebra, are computer free
The simple classical groups of dimension less than 6 which are (2,3)-generated
In this paper we determine the classical simple groups of dimension r=3,5
which are (2,3)-generated (the cases r = 2, 4 are known). If r = 3, they are
PSL_3(q), q 4, and PSU_3(q^2), q^2 9, 25. If r = 5 they are PSL_5(q), for
all q, and PSU_5(q^2), q^2 >= 9. Also, the soluble group PSU_3(4) is not
(2,3)-generated. We give explicit (2,3)-generators of the linear preimages, in
the special linear groups, of the (2,3)-generated simple groups.Comment: 12 page
The -generation of the finite unitary groups
In this paper we prove that the unitary groups are
-generated for any prime power and any integer . By
previous results this implies that, if , the groups and

Shot noise in resonant tunneling structures
We propose a quantum mechanical approach to noise in resonant tunneling
structures, that can be applied in the whole range of transport regimes, from
completely coherent to completely incoherent. In both limiting cases, well
known results which have appeared in the literature are recovered. Shot noise
reduction due to both Pauli exclusion and Coulomb repulsion, and their combined
effect, are studied as a function of the rate of incoherent processes in the
well (which are taken into account by means of a phenomenological relaxation
time), and of temperature. Our approach allows the study of noise in a variety
of operating conditions (i.e., equilibrium, sub-peak voltages, second resonance
voltages), and as a function of temperature, explaining experimental results
and predicting interesting new results.Comment: RevTeX file, 26 pages, 3 Postscript figures, uses epsf.sty. submitted
