Abstract
Purpose
The purpose of this study was to develop and apply new physical heart defect models (PHDMs) that are patient-specific and color-coded with an optimized map.
Design/methodology/approach
Heart defect anatomies were segmented from medical images and reconstructed to form virtual models, which were then color-coded and rapid prototyped. The resulting PHDMs were used in a medical educational study to evaluate their pedagogical efficacy and in clinical case studies to investigate their utility in surgical planning.
Findings
A growing library of 36 PHDMs (including the most common defects) was generated. Results from the educational study showed that the PHDMs enabled uniquely effective learning, and the clinical case studies indicated that the models added value as surgical planning aids.
Research limitations/implications
The education study involved a limited number of students, so future work should consider a larger sample size. The clinical case studies favored use of the PHDMs in surgical planning, but provided only qualitative support.
Practical implications
Workflow optimization is critical for PHDMs to be used effectively in surgical planning because some operations must be performed in emergently.
Social implications
Because PHDMs have potential to influence surgeons’ actions as surgical planning aids, their use in that context must be thoroughly vetted.
Originality/value
The proposed models represent the first PHDMs that are patient-specific and fully color-coded with a standardized map optimized for the human visual system. The models enhanced medical education and facilitated effective surgical planning in this study.

Abstract
In April 1988, the National Reference Center for Bioethics Literature (NRC) (see sidebar) published “AIDS: Law, Ethics and Public Policy.” As part of the NRC's Scope Note Series, the paper offered a current overview of issues and viewpoints related to AIDS and ethics. Not meant to be a comprehensive review of all AIDS literature, it contained selected citations referring to facts, opinion, and legal precedents, as well as a discussion of different ethical aspects surrounding AIDS. Updating the earlier work, this bibliography provides ethical citations from literature published from 1988 to the present.

Abstract
Parental illness can affect child and adolescent psychosocial well‐being. Mental health effects of parental bereavement generally and HIV‐related bereavement specifically have been poorly explored in children. HIV‐related illness has a number of specific features that may directly affect mental health considerations. Infection is clustered in families. Bereavement is often multiple. Death is often preceded by severe illness and multiple opportunistic infections. AIDS is stigmatised, which may impede disclosure, social support and adjustment. In low‐income countries where HIV infection is concentrated, access to palliative care as well as medical care may be limited. This review systematically identifies studies on HIV and bereavement in children. Searches of electronic databases for relevant articles revealed 14 studies examining bereavement with sufficient measurement and controlled methodology providing standardised behavioural and emotional outcome measures. Scrutiny of the results revealed the majority (12: 86%) recorded an adverse behavioural or emotional impact on the child. A detailed analysis of the studies provides insights to risks as well as protective factors that may inform future interventions. Only one systematic intervention was identified whereby a coping skills intervention had positive and long‐lasting effects. This paper examines urgent future needs and the requirement for evidence‐based policy and provision.

Abstract
The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

Abstract
Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Abstract
Purpose
The historic assets are heterogeneous and different to each other, and for this reason, consolidated valuation methodologies do not exist in practice or in the literature. It is, therefore, necessary to dwell on the study of a particular historic building type or category. The assessment process of the valuers of Venetian Villas was explored, focusing on the study of the valuation function construction. The paper investigated if a possible value function, based on the partition of the characteristics, which significantly influence the value, exists and it is generalizable to the whole set of Venetian Villas. The purpose of this paper is to contribute knowledge on the economic valuation of Venetian Villas.
Design/methodology/approach
An application of Hedonic Pricing study to a database of 71 Venetian Villas has been tested. This statistical procedure allowed the authors to discover which results in a percentage of property values can be attributed to the historical characteristics of a building. Using a multiple linear regression and its variables an analysis of residuals and data relating to the variance has been performed.
Findings
This research identifies and proposes, therefore, a valuation approach that can be generalizable to the whole set of Venetian Villas (over 4,000 properties). The models show that the most important variables which influence the value of the villas are: age, internal and external area, maintenance conditions, and author. This model could be used for future valuations of the same type of asset.
Originality/value
The model enables valuers to address better to the property valuation of the Venetian Villas through the valuation functions, which suggest which are the main features which focus in the case of a Venetian Villa valuation and what impact they have on the value asset. The model can be specifically used for valuation reports in the enhancement project of such properties.
