Mental health providers will be increasingly called on to lead psychiatric efforts to improve care and care redesign. The Accreditation Council for Graduate Medical Education (ACGME) in the USA requires residency programs to teach quality improvement (QI) and systems-based practice (SBP) to all trainees as part of training requirements. However, teaching QI and SBP concepts without a clinical context can be challenging with low trainee engagement. The paper aims to discuss these issues.

The authors describe curricular redesign with a specialized educator faculty task force that aimed to create a longitudinal curriculum that integrated abstract QI concepts into clinical practice settings, and helped trainees apply SBP concepts throughout residency. In addition, the authors describe the utilization of resident prescriber profiles to contextualize clinical practice habits, and the implementation of an educational case conference series with emphasis on QI-specific educational tools such as root cause analysis (RCA).

Formal resident feedback from 2016 to 2018 has demonstrated improved trainee satisfaction. The resulting curricular change has also led to a new chief resident role and sustained engagement in QI and SBP education by trainees.

The faculty task force and curricular design changes described in this paper were implemented at one large academic institution. Thus, additional assessment and research is necessary to address the generalizability of the interventions described.

Since QI and SBP are becoming more prominent requirements for medical education accrediting bodies such as the ACGME, the innovative curricular design can benefit other residency and medical student education programs that attempt to integrate clinical practice with education incorporating QI and SBP concepts.

It is a challenge to print a model with the size that is larger than the working volume of a three-dimensional (3D) printer. The purpose of this paper is to present a feasible approach to divide a large model into small printing parts to fit the volume of a printer and then assemble these parts into the final model.

The proposed approach is based on the skeletonization and the minima rule. The skeleton of a printing model is first extracted using the mesh contraction and the principal component analysis. The 3D model is then partitioned preliminarily into many smaller parts using the space sweep method and the minima rule. The preliminary partition is finally optimized using the greedy algorithm.

The skeleton of a 3D model can effectively represent a simplified version of the geometry of the 3D model. Using a model’s skeleton to partition the model is an efficient way. As it is generally desirable to have segmentations at concave creases and seams, the cutting position should be located in the concave region. The proposed approach can partition large models effectively to well retain the integrity of meaningful parts.

The proposed approach is new in the rapid prototyping field using the model skeletonization and the minima rule. Based on the authors’ knowledge, there is no method that concerns the integrity of meaningful parts for partitioning. The proposed method can achieve satisfactory results by the integrity of meaningful parts and assemblability for most 3D models.

We have developed a two‐dimensional model for quantum‐well lasers which solves, self‐consistently, the semiconductor equations together with the complex scalar wave equation and the photon rate equation. To predict the threshold current accurately we have included the wavelength‐ and position‐dependence of the gain and the spontaneous emission. For the complex wave equation successive over relaxation (SOR) is used with two adaptive acceleration parameters for the complex wave amplitude and for the eigenvalue. Since the rate equation near threshold can be driven into divergence during iteration for a steady state solution, we have introduced a special damping technique to overcome this problem. Our model enables us to predict the characteristics of a quantum‐well laser with a minimal number of empirical constants. The output of the model includes light‐current characteristics, and the current and optical field intensity distributions. We show the results of a calculation for a graded‐index separate‐confinement heterostructure single quantum‐well (GRIN‐SCH SQW) laser.

This article questions the validity of regression models when high correlations exist between independent variables and presents the application of VAR as an alternative technique through the comparison of two groups of selected stocks that represent components of Dow Jones and S&P 500 indices, respectively. The results indicate that panel regressions face serious specification problems, while the impulse response function underlines that the shock to the volume innovation has a mostly positive impact on the volatility in both S&P and Dow Jones sample, but the tendency cannot be easily accounted for. The positive impact of volatility shocks on the inter market depth is rather unexpected, but it may be associated with an increase in volume that does not enormously enhance the spread up to the point where it will be too costly for market‐makers to trade, and accordingly, quickly narrows the spread to absorb new liquidity influx in the market. In the Granger causality tests Dow Jones stocks with comparatively larger average volume depth values and price levels provide slightly stronger relations between analyzed variables compared to the stocks included in the S&P sample.

Few librarians think of U.S. documents as a source for professional reading, growth, and information, yet several agencies of the government are involved with library programs, services, and research. This bibliography is a compilation of some of the most recent documents about libraries published by these agencies. It is an eclectic group, ranging from scholarly research studies to descriptions of model programs. Most of these studies are known only to a small segment of the library profession and have not received wide distribution in the field. The quality of the documents is quite good, particularly the research reports being done out of the Department of Education's Office of Educational Research and Improvement (OERI) Library Programs Office. Much of the information contained in the surveys and research reports is not available in any other form.

In prior articles in both volume 8 (number 4) and volume 10 (numbers 3/4) of Collection Building, bibliographies of U.S. government publications on AIDS were covered. The first bibliography covered both executive branch and legislative branch materials from 1981 to September 1986. The second bibliography covered only legis‐lative materials from 1986 to 1989. This article complements the second bibliography in its coverage of executive branch materials from 1986 to 1989 and also updates the first work. While 1986 to 1989 is the framework, some items inadvertently omitted from the earlier work are included here.

This study aims to understand the epistemic foundation of the classification applied in the first Chinese library catalogue, the Seven Epitomes (Qilue).

Originating from a theoretical stance that situates knowledge organization in its social context, the study applies a multifaceted framework pertaining to five categories of textual data: the Seven Epitomes; biographical information about the classificationist Liu Xin; and the relevant intellectual, political, and technological history.

The study discovers seven principles contributing to the epistemic foundation of the catalogue's classification: the Han imperial library collection imposed as the literary warrant; government functions considered for structuring texts; classicist morality determining the main classificatory structure; knowledge perceived and organized as a unity; objects, rather than subjects, of concern affecting categories at the main class level; correlative thinking connecting all text categories to a supreme knowledge embodied by the Six Classics; and classicist moral values resulting in both vertical and horizontal hierarchies among categories as well as texts.

A major limitation of the study is its focus on the main classes, with limited attention to subclasses. Future research can extend the analysis to examine subclasses of the same scheme. Findings from these studies may lead to a comparison between the epistemic approach in the target classification and the analytic one common in today's bibliographic classification.

The study is the first to examine in depth the epistemic foundation of traditional Chinese bibliographic classification, anchoring the classification in its appropriate social and historical context.

We open a new volume of The Library World in circumstances combining hope and difficulty. The hope rests upon the knowledge that library authorities are free when and as they choose to give Great Britain libraries equalling those of the United. States and Canada. The difficulty is in the immediate financial crisis facing the country, a crisis which is partly real, partly a political stunt, and is certainly potent enough to impede any great progress for the moment. There will be real struggle in many cases and hardship perhaps in a few, and the need for mutual consultation and advice, such as this magazine provides, was never greater. Nor must it be supposed that, because we seem to refer more particularly to municipal libraries here, every other form of library, public or private, will not directly or indirectly be affected by the same influences, and be equally in need of such a medium as this. Wo have never declared any cast‐iron policy in regard to The Library World—its very freedom from fixed views has been one of its chief recommendations—but at the beginning of an editorial year a few words on our aims are not inappropriate.

The foundation collection of the printed books now forming the Library of the British Museum was that of Sir Hans Sloane. This comprised about 40,000 volumes. To it was added in 1759 the Royal collection, begun in the time of Henry VII and inherited by George II from his predecessors on the throne.
