Abstract
THIS subject would be irrelevant to airmen but for the facts that, firstly, the Japanese war is clearly a more amphibious affair than war nearer home, and secondly, the Japanese (according to British experience, doubtless confirmed by the Americans) will go to extraordinary lengths to destroy even one man and have no scruples over emptying their bombracks among surviving airmen in the water if there is no better target.

Abstract
We examine the stability of market prices for 35 technology and 35 industrial stocks for the period December 31, 1993 to October 31, 2002. A phase portrait plot of the detrended log prices and de‐meaned returns of the two sectors shows a chaotic pattern in the stock prices indicating the presence of nonlinearity. However, when we compute the Lyapunov exponents, negative values are obtained. This shows that the price fluctuations for the 70 stocks result primarily from diffusion processes rather than from nonlinear dynamics. We evaluate forecast errors from a naïve model, a neural network, and ARMA models and find that the forecast errors are correlated with average changes in closed‐end fund discounts and other sentiment indexes. These results support an investor sentiment explanation for the closed‐end fund puzzle and behavioral theories of investor overreaction.

Abstract
Purpose
The purpose of this paper is to identify how organizations can evaluate the green product deletion decision within an environmentally sustainable consumption and production environment through a hybrid multistage multiple criteria evaluation approach.
Design/methodology/approach
This paper proposes a decision-making model by integrating “soft computation” using neighborhood rough set theory, fuzzy cluster means, and cumulative prospect theory. Literature is used to identify various factors for the decision environment. An illustrative problem provides insights into the methodology and application.
Findings
The results indicate that green products can be evaluated from both their relative environmental burdens and benefits. Sustainable consumption and production factors that play a role in this multifactor decision are identified. The results show that a comprehensive evaluation can capture an effective overall picture on which green product(s) to delete.
Research limitations/implications
The opaqueness of the proposed methodology may cause less acceptance by management. The methodology made a number of assumptions related to the data. An actual application of the tool rather than just an illustrative example is needed.
Originality/value
The main contribution of this study is the novel integration of supply chain perspectives, both upstream (supply and production) and downstream (demand/usage), with green product deletion decision making. The hybrid multistage technique has advantages of being able to incorporate many factors that have a variety of quantitative and qualitative characteristics to help managers address green product deletion issues as well as its impact on greening of supply chains and organizational environmental sustainability. This paper adds value to product deletion, supply chain management, and sustainable production and consumption literatures.

Abstract
A hybrid formulation is proposed that incorporates finite element substructuring and Galerkin boundary elements in the numerical solution of Poisson's or Laplace's equation with open boundaries. Substructuring the problem can dramatically decreases the size of matrix to be solved. It is shown that the boundary integration that results from application of Green's first theorem to the weighted residual statement can be used to advantage by imposing potential and flux continuity through the contour which separates the interior and exterior regions. In fact, the boundary integration is of exactly the same form as that found in Galerkin boundary elements.

Abstract
This paper discusses statistical analyses of the effect of reductions in opening hours on book issues of public library authorities (PLAs). Monthly issue statistics over a three‐ to four‐year period for twenty‐six libraries in four PLAs (Sheffield, Ealing, Hereford and Worcester, and Lancashire) were analysed using graphic analysis and time series modelling. The results, with one or two exceptions, showed little, if any, significant relationship between reductions in hours and book issues. There were indications that other variables such as seasonality, patterns of opening hours and the accessibility of other libraries might be masking any impact. Annual issue and book fund statistics over a twenty‐three year period for libraries in Sheffield PLA were also analysed. This latter investigation suggests that reductions in the level of issues, related to both opening hours and materials expenditure, are discernible after a period of about two years. One model showed that the impact of opening hours cuts may be discernible within a year, materials fund cuts after a lag of one to two years. The study demonstrates clearly the difficulties involved in using statistical data to make accurate predictions of the impact of individual reductionsin opening hours on book issues. It identifies a number of variables which may affect the impact of reductions.

Abstract
Zoning is typically deemed a negative‐sum game accompanied by a call for the establishment of a market for development rights. Using a formal one‐stage game of a typical zoning lottery, I demonstrate that zoning is not exclusively negative‐sum, but can also be positive‐sum, even with internalized social costs.

Abstract
This paper presents a computationally efficient numerical solution scheme to solve transient heat conduction problems using the boundary element method (BEM) without volume discretization. Traditionally, a transient solution using BEM is very computer intensive due to the excessive numerical integration requirements at each time increment. In the present work a numerical solution scheme based on the separation of time and space integrals in the boundary integral equation through the use of an appropriate series expansion of the integrand (incomplete gamma function) is presented. The space integrals are evaluated only once in the beginning and within each time increment the additional integrals are obtained from the previously evaluated space integrals by a simple calculation. Three‐dimensional applications are provided to compare the proposed strategy with that used traditionally. The CPU requirements are reduced substantially. The solution scheme presented allows for dynamically changing the time step size as the solution evolves. This feature is not practical in the traditional schemes based on boundary discretization only.

Abstract
The following definitions and standards for food products have been adopted as a guide for the officials of this Department in enforcing the Food and Drugs Act. These are standards of identity and are not to be confused with standards of quality or grade; they are so framed as to exclude substances not mentioned in the definition and in each instance imply that the product is clean and sound. These definitions and standards include those published in S. R. A., F. D. 2, revision 4, and those adopted October 28, 1936.

Abstract
This survey of psychology periodicals was begun whilst the library of the British Psychological Society was still in Nottingham, and was intended to reduce the difficulties of the research worker in psychology in London. Thirty‐nine London libraries most helpfully supplied information on their holdings in seventy‐nine selected periodicals. Librarians also suggested other periodicals for inclusion in the list, and, as a growing number of individuals became interested, the list of periodicals grew during the last two years to its present total of 179.

Abstract
Purpose
The COVID-19 pandemic caused major disruption in community support for vulnerable older people and is thought to have exacerbated existing issues within UK adult social care. This study aims to examine the legacy of that disruption on how meeting centres for people affected by dementia have been impacted in continually evolving circumstances.
Design/methodology/approach
Semi-structured interviews and focus group discussions were conducted at three meeting centre case study sites. Ninety-eight participants, including people living with dementia, family carers, staff, volunteers, trustees and external partners, were asked about the impact and legacy of the pandemic upon meeting centres. A thematic analysis was carried out on the data.
Findings
Ten themes were identified: ability to re-open venues; increased health decline and loss of members due to isolation; closure or halting of linking services and dementia community support; disruption to diagnosis and referrals; increase in outreach, building communities and overall reach; digital access and use of technology (boom and decline); changes to carer involvement and engagement; continued uncertainty and changes to funding, resources and governance; staff and volunteer recruitment issues; and relief at/wish for return to pre-pandemic norms.
Originality/value
This paper offers new insight into a still-developing situation, namely, the legacy effects of the pandemic upon third-sector community support for people affected by dementia and the health and social care services that support it. The reduction in maintenance of pandemic-era technological innovations is a key finding.
