The purpose of this paper is to develop an yield-based process capability index (PCI), C _py, to overcome the shortcomings of existing PCIs that limit their use and lead to inaccurate measures of quality conformance under a variety of common conditions.

–C _py is developed conceptually to flexibly and accurately reflect conformance and then used to numerically measure inaccuracies of C _pk.

–C _py overcomes many of the problems associated with existing PCIs, including C _pk. The degree of process distribution non-normality, level of quality (the sigma level), and whether the process is centered or shifted left or right affect the direction and size of process capability error produced by C _pk. The accuracy of C _pk can be greatly affected by process data that deviate even slightly from normality.

–C _py offers numerous advantages compared to existing PCIs. It accurately reflects process conformance regardless of the process distribution. It is applicable even if the process has multiple characteristics and with both variable and attribute data. Its calculation is relatively simple and the necessary data for it are likely already captured by most organizations.

The main contributions are the development of a new PCI, C _py; a conceptual analysis of its advantages; and a numerical analysis of the improved accuracy of C _py as compared to C _pk for shifted and non-shifted process means for normal, nearly normal, and highly non-normal distributions over a range of process variability levels.

The purpose of this paper is to investigate the performance implications associated with production outsourcing. Specifically, the paper analyzes the cost of goods sold for firms who outsource core manufacturing processes, using empirical data from a variety of industries. The paper seeks to better understand the influence of outsourcing on factory cost by looking at these in the context of related strategies, such as supplier integration, information technology (IT) implementation, and manufacturing process decisions.

The paper draws on transaction cost economics, manufacturing strategy, and supply chain management literature to aid in predicting the performance to be expected when outsourcing production activities. Furthermore, the paper investigates the moderating effects of manufacturing strategies, supplier integration, and IT expenditures on outsourcing. The primary model is a two-way panel model for the cross-sectional and longitudinal data drawn from the MPI Census of Manufacturers Survey of US manufacturing plants.

The analysis indicates that production outsourcing tends to shift costs among cost of goods sold (COGS) categories, but does not consistently reduce them as measured by overall COGS. The effects of production outsourcing on both the cost of labor and the cost of materials are strong, tending to decrease labor, and increase materials. Additionally, this study shows that a high level of supplier integration has a notable moderating influence on overall COGS, but that process strategies do not. Finally, this analysis indicates that IT expenditures were not influential as a moderator variable when outsourcing, but did have a marked influence on overall COGS, as well as on labor and materials costs.

This research investigates the effects of outsourcing on the components of COGS, a level of analysis that is typically not looked at relative to outsourcing. This research also provides methodological contributions with the development of a nested random effects structural model for use with a secondary data source.

MID‐SEPTEMBER, with the summer gone irrevocably, allows the librarian a fortnight of reflection time before the strenuous interests of autumn and winter become active. That is, if he returns stimulated in body and mind from a reasonable holiday and does not become immersed immediately in the almost compelling series of meetings of librarians arranged for the last fortnight of September and for October. For the student members the Birmingham Summer School remains in session until the 20th; for their elders ASLIB will confer at Swanwick from the 19th to 21st, and, in the same week‐end at Buxton, there will be the conference on library work for children; and, a week later, 26th to 29th, the University and Research Section will occupy Lady Margaret Hall at Oxford. The arrangements for October are set out in the L. A. Record. Their profusion embarasses many librarians. It is only natural that, as librarianship extends, every organized part of it becomes keenly aware of its individuality and, as the profession today grows more and more conference‐minded, few can keep step, save in a general way, with more than a fraction of the meetings arranged. Some effort is made by the L.A. and by librarians to preserve and strengthen the basic unity of all librarianship, but otherwise the diversity is great.

Prominence is given in this issue to the interesting Diamond Jubilee celebration held last month in connection with the Norwich Public Library. It was a courageous but entirely proper thing to hold this celebration in war time, because although it was calculated to raise opposition from short‐sighted people, at the same time it was good policy to affirm that the Public Library is an essential part of national economy even in the greatest of wars. Excellent arguments on behalf of this last proposition were advanced at that meeting in the happy speech made by Mr. L. Stanley Jast, which we hope to see published in even fuller form sooner or later, and equally in the letter from Sir Frederic Kenyon. This gains greatly in force from the fact that Sir Frederic is not only an officer in the Army, but is, we believe, at this moment serving in France. If any of our readers have had doubts about the present seasonableness of their work, and there may conceivably be such, they may wisely ponder the letter and again take heart of grace. As for the celebration as a whole, it was, as we have said, opportune; it was also skilfully engineered and advertised, and was an undoubted success upon which the Norwich Library Committee and Mr. G. A. Stephen have every reason to congratulate themselves.

BY February most of the parties, which are a gracious feature of modern libraries, are over. They arise from Staff Guilds, which now in most libraries associate the workers, and some of them are on a large scale. We have been represented at only a few of these but there seems to be a great fund of friendliness upon which the modern librarian can draw nowadays. An interesting one was that of the National Central Library Staff which, by a neighbourly arrangement, was held at Chaucer House. A reunion has been held of old and new members of the Croydon Staff Guild and no doubt there were many others. One New Year party was a small but notable dinner at Charing Cross Hotel where the 100th issue of The Library Review was toasted eloquently by the President of the Library Association and amongst the guests were Mr. C. O. G. Douie who was secretary of the Kenyon Committee of the 1927 Library Report and well‐known librarians and journalists. To us it was notable for the assertion by Mr. R. D. Macleod that amongst the young writers were too many who wrote glibly but without that research which good professional writing demanded; but he was sure that where intelligent industry was shown any article resulting would find a place in library journals.

Against a backdrop of an increasingly younger terrorist cohort within His Majesty’s Prison and Probation Service, this study aims to explore the relationship between age and various Extremism Risk Guidance 22+ (ERG22+) assessment outcomes.

A database of 490 individuals was developed by coding content of ERG22+ reports from 2010 to 2021, equating to nearly all cases in England and Wales across this time period. Socio-demographic information, offending histories, online activities and risk factors were coded for all individuals. This study focuses on 465 individuals convicted of terrorist/terrorist-related offending, with statistical analyses used to compare three age groups: “20 and under” (61 cases), 21–25 (133 cases) and “26 and over” (271 cases).

Significant associations were found between presence of certain behaviours/characteristics and age groups. For those aged 20 and under, a heightened propensity for excitement, comradeship and adventure, along with greater susceptibility to influence and need for status were generally key to offending pathways, with a diminished likelihood of a prior criminal history. Of the three ERG22+ dimensions, findings indicate a weak but significant negative correlation between age and engagement levels.

Recommendations include ensuring extremism risk assessments reflect age-specific behaviours and tendencies, that interventions are tailored to address common age-related vulnerabilities, and the need for age-specific policies to support and manage children and young adults within the counter-terrorism space.

These novel findings point towards notable developmental milestones in adolescence, affecting behavioural tendencies and risk. This underscores the importance of age as a determinant when interpreting extremism risk assessments.

The aim of this publication is to list the catalogues of the Department of Manuscripts which are in regular use. Catalogues which have been superseded by later publications are not normally included, since whatever their historical or bibliographical interest they are no longer everyday working tools. To save space in cross‐reference, the catalogues, etc., here listed have been numbered serially in Clarendon type, thus: 31. This numeration has no other significance.
