Nonempirical Calculations on Excited States: The Ethylene Molecule
A series of nonempirical calculations are reported on the excited states of the ethylene molecule using a recent minimum basis set LCAO MO SCF wavefunction. For the lowest excited singlet state of ethylene (^1B_(3u)) the coupling between the π electrons and σ electrons is significant: the excitation energy being decreased from 11.98 to 10.17 eV and the oscillator strength from 1.03 to 0.73. This coupling has little effect on the triplet state. In the next higher approximation (the random‐phase approximation) the excitation energy is further decreased to 9.44 eV and the transition moment to 0.51. With the use of accurate LCAO MO SCF wavefunctions, it is felt that the methods presented here will provide a basis for the theoretical interpretation of electronic spectra

Equivelar and d-Covered Triangulations of Surfaces. I
We survey basic properties and bounds for -equivelar and -covered
triangulations of closed surfaces. Included in the survey is a list of the
known sources for -equivelar and -covered triangulations. We identify all
orientable and non-orientable surfaces of Euler characteristic
which admit non-neighborly -equivelar triangulations
with equality in the upper bound
. These
examples give rise to -covered triangulations with equality in the upper
bound . A
generalization of Ringel's cyclic series of neighborly
orientable triangulations to a two-parameter family of cyclic orientable
triangulations , , , is the main result of this
paper. In particular, the two infinite subseries and
, , provide non-neighborly examples with equality for
the upper bound for as well as derived examples with equality for the upper
bound for .Comment: 21 pages, 4 figure
An analysis of the National War College
The higher education\u27s voluntary system of self-regulation is the accreditation process which recognizes institutions and their degrees with an established level of performance, integrity, and quality entitling them to the confidence of the educational community and the public they serve.;It was hypothesized that if the National War College fits the model of a professional school and volunteers to seek accreditation, then the benefits of the accreditation process will provide for an enhanced program and successful accreditation will enhance the professional status of the National War College in the higher education community.;In addition to the hypothesis, the study considered how military professional military education fits into the community of higher education, whether regional or specialized accreditation was more appropriate for the National War College, why accreditation was sought, and what external influences impacted accreditation.;The accreditation process was examined through a qualitative case study on the National War College by testing Alexander Flexner\u27s model for a profession and the paradigm of William Selden and Harry Porter.;It was concluded that the profession of arms resembled the Flexner model for a profession and that the accreditation process will benefit the National War College as it does more traditional institutions.;In addition, it was concluded that regional accreditation was the most appropriate method of recognition over specialized accreditation.;In sum, it was concluded that professional military education had a legitimate niche in higher education. While this research provides a basis for understanding professional military education, more research will further assist academicians understand this widely misunderstood profession. Most importantly, it was shown that the accreditation process is applicable for federal-degree granting institutions which are atypical of most member institutions of accreditation bodies
Asymptotic extreme-value distributions of wave heights in the open ocean
Application of the Fréchet extreme-value distribution to extreme wave heights is discussed. Annual extreme significant wave-height data for 12 Ocean Station Vessels have been fitted by the distribution. These distributions have been adjusted to extreme wave-height distributions by applying a scale transformation to the significant wave-height distributions based on previous theoretical and empirical studies of wave-height observations
Challenges to providing culturally sensitive drug interventions for black and Asian minority ethnic (BAME) groups within UK youth justice systems
To explore how substance use practitioners intervene with ethnically and culturally diverse groups of young people in contact with the youth justice system.
Telephone, face to face interviews and a focus group were conducted. Data were analysed thematically using a frame reflective theoretical approach.
Practitioners tended to offer individualised interventions to young people in place of culturally specific approaches partly due to a lack of knowledge, training or understanding of diverse cultural needs, and for practical and resource reasons.
Practitioners reject the official narrative of BAME youth in the justice system as dangerous and in need of control, viewing them instead as vulnerable and in need of support but report they lack experience, and sufficient resources, in delivering interventions to diverse groups.
There is little information regarding how practitioners respond to diversity in their daily practice. This paper is an exploration of how diversity is framed and responded to in the context of youth substance use and criminal justice
Framing 'drug prevention' for young people in contact with the criminal justice system in England: views from practitioners in the field
Drawing on the work of Rein and Schon (1993; 1996), we explore the ways in which ‘young people’, ‘vulnerability’, ‘risk’, ‘prevention’ and ‘prevention practice’ were defined and framed by practitioners engaged in the design, delivery and commissioning of drug prevention interventions for young people in contact with the criminal justice system. We argue that practitioners describe their work in terms of both a preventative frame – based on a ‘deficit’ model - and a transformative praxis frame, more in line with an increasing shift towards ‘positive youth justice’ where practitioners aspire to actively involve the young person in a process of change. The implications of those, often competing, frames are discussed in relation to the development of prevention approaches and the challenges in designing drugs prevention for this group of young people. The paper is based on interviews and focus groups with thirty-one practitioners in England and is part of the EU funded EPPIC project (Exchanging Prevention Practices on Polydrug Use among Youth in Criminal Justice Systems 2017-2020)

Five Approaches to Literacy in Correctional Education
This article introduces literacy from a few “big picture” perspectives, and then reviews five paradigms that have shaped the teaching and learning of literacy in residential confinement institutions for juveniles and adults. The paradigms are specific to correctional education, but they will be familiar to all alternative teachers and advocates of literacy instruction
