Abstract
Purpose
The purpose of this paper is to describe the key elements of a major work programme on dementia, and to reflect on the practical learning derived.
Design/methodology/approach
The paper describes the whole range of programme activity, including research projects, think-pieces, action research, demonstrations, evaluations and production of resources such as films, infographics, case studies, practice guides and positive image galleries.
Findings
The active, meaningful engagement of people with dementia and their families is fundamental. Communities must engage with, and achieve equity for, all people with dementia, whatever their circumstances. Practical barriers to inclusion must be addressed if normal lives are to be continued. The human rights of people with dementia and carers must be recognised and promoted. Local grassroots community activity is the bedrock of dementia friendly communities – but this activity must be supported by strong strategic planning, commissioning and leadership. There is no template – each community must develop its own approach.
Practical implications
The paper highlights many examples of good practice which can inform the work of commissioners and practitioners, as well as wider communities. These focus particularly on good practice in engagement and involvement; and the co-production of dementia friendly communities with people with dementia.
Social implications
The programme highlights the importance of social barriers to the inclusion of people with dementia in their communities, and gives examples of communities which have tried to overcome these through attitudinal and environmental change.
Originality/value
Joseph Rowntree Foundation’s programme is highly innovative and well-regarded.

Abstract
Explores damp in the context of historic buildings, explaining why these structures require an individualistic approach. Outlines historic building materials and construction and the history of damp treatments. Discusses the causes of damp related damage, concentrating on direct penetration of rainwater, rising damp, condensation and hydroscopic salts. Details the principles of historic pointing and rendering, and the differences in modern techniques, touching on preventatives such as leadwork, water repellents and consolidants. Concludes that the primary consideration when working on any aspect of historic building work is that any clash between building conservation and human comfort ought to favour the building.

Abstract
Purpose
This paper aims to concentrate on the impacts of a discrete heat source location on heat transfer and entropy generation for a Ag-water nanofluid in an open inclined L-shaped cavity.
Design/methodology/approach
The governing partial differential equations for this study are computed by the finite volume method.
Findings
The results show that increasing the inclination angle leads to a rise in heat transfer. It is clear with the increase in the nanoparticles volume fraction that the thermal performance reduces, and it increases when the inclination angle increases.
Originality/value
Because of the continuous literature survey, the authors have not found a study that concentrates on the entropy generation in a wide variety of irregular ducts. Thus, in this paper, they present the analysis of entropy generation in an L-shaped duct experiencing a mixed convective flow with a nanofluid. The authors deal with this geometry because it is very useful in cooling systems of nuclear and chemical reactors and electronic components.

Abstract
TIME was when the prisoner was regarded as a sort of object with no rights worth talking about, and whose views were of no account. His life was largely in the hands of jailers who did their job thoroughly, and whose brutality in cases provides a desperate record. The prisoner was hardly in a position to complain. Nowadays it would appear that some of our prisons are quite jolly places, to which large sections of the population are delighted to resort when they feel they need a rest cure.

Abstract
Purpose
The purpose of this study is to present the significance of Joule heating, viscous dissipation, magnetic field and slip condition on the boundary layer flow of an electrically conducting Boussinesq couple-stress fluid induced by an exponentially stretching sheet embedded in a porous medium under the effect of the magnetic field of the variable kind. The heat transfer phenomenon is accounted for under thermal radiation, Joule and viscous dissipation effects.
Design/methodology/approach
The governing nonlinear partial differential equations are transformed to the nonlinear ordinary differential equations (ODEs) by using some appropriate dimensionless variables and then the consequential nonlinear ODEs are solved numerically by making the use of the well-known shooting iteration technique along with the standard fourth-order Runge–Kutta integration scheme. The impact of emerging flow parameters on velocity and temperature profiles, streamlines, local skin friction coefficient and Nusselt number are described comprehensively through graphs and tables.
Findings
Results reveal that the velocity profile is observed to diminish considerably within the boundary layer in the presence of a magnetic field and slip condition. The enhanced radiation parameter is to decline the temperature field. The slip effect is favorable for fluid flow.
Originality/value
Till now, slip effect on Boussinesq couple-stress fluid over an exponentially stretching sheet embedded in a porous medium has not been explored. The present results are validated with the previously published study and found to be highly satisfactory.

Abstract
Purpose
This paper aims to give an account – using photographs as well as words – to describe a North American indigenous community that is retaining pre‐contact Promethean values.
Design/methodology/approach
The paper adopts as its approach ethnographic literature and field interviews coupled with extensive photography.
Findings
Entrepreneurship may be linked to Promethean values, a characteristic of Pueblo Indians who were imaginatively original, long before the arrival of Europeans. Since ancient times, the use of irrigation in agriculture allowed the Pueblo Indians to reside in permanent houses; these two features – sophisticated farming and settlements – resulted in these indigenous people being unlike their nomadic neighbours. Farming – as opposed to hunting – was the backbone of the Pueblo economies, and theocratic government developed to control land and water usage; complex religious ceremonies became prerequisites to harvests. Religion taught discipline, and religious values remain important. Discipline – significant in this community even today – may be the causal variable explaining Promethean over Dionysian values.
Research limitations/implications
Future research might examine further differences between indigenous groups.
Practical implications
Regardless of how religious a person is, values perpetuated by religion can transcend to a generation that practises them less than their elders. In the case of Taos Pueblo Indians, traditional Promethean values are being perpetuated, including a highly disciplined work ethic.
Originality/value
The paper suggests that entrepreneurship values may be linked to traditional religion and historic innovation.

Abstract
Thermally driven flow in a tall inclined cavity bounded by porous layers is studied analytically and numerically. A constant heat flux is applied for heating and cooling of two opposing walls of the cavity, while the other two are insulated. The Beavers—Joseph slip condition on velocity is applied at the interface between the fluid and porous layers. An analytical solution is obtained by assuming parallel flow in the core region of the cavity and a numerical solution by solving the complete governing equations. The flow and heat transfer variables are obtained in terms of the Rayleigh number, Ra, slip condition parameter N and angle of inclination of the cavity Φ. The critical Rayleigh numbers for the onset of convection in a layer heated from below are predicted for various hydrodynamic boundary conditions. The results for a fluid layer bounded by solid walls (N → ∞) and by free surfaces (N → 0) emerge from the present analysis as limiting cases.

Abstract
President Bill Clinton has had many opponents and enemies, most of whom come from the political right wing. Clinton supporters contend that these opponents, throughout the Clinton presidency, systematically have sought to undermine this president with the goal of bringing down his presidency and running him out of office; and that they have sought non‐electoral means to remove him from office, including Travelgate, the death of Deputy White House Counsel Vincent Foster, the Filegate controversy, and the Monica Lewinsky matter. This bibliography identifies these and other means by presenting citations about these individuals and organizations that have opposed Clinton. The bibliography is divided into five sections: General; “The conspiracy stream of conspiracy commerce”, a White House‐produced “report” presenting its view of a right‐wing conspiracy against the Clinton presidency; Funding; Conservative organizations; and Publishing/media. Many of the annotations note the links among these key players.

Abstract
Purpose
The purpose of this study is to analyze the build quality and compression properties of thin-walled 304L honeycomb structures manufactured by selective laser melting. Four honeycomb wall thicknesses, from 0.2 to 0.5 mm, were built and analyzed.
Design/methodology/approach
The density of the honeycombs was changed by increasing the wall thickness of each sample. The honeycombs were tested under compression. Differences between the computer-assisted design model and the as-built structure were quantified by measuring physical dimensions. The microstructure was evaluated by optical microscopy, density measurements and microhardness.
Findings
The Vickers hardness of the honeycomb structures was 209 ± 14 at 50 g load. The compression ultimate and yield strength of the honeycomb material were shown to increase as the wall thickness of the honeycomb samples increased. The specific ultimate strength also increased with wall thickness, while the specific yield stress of the honeycomb remained stable at 42 ± 2.7 MPa/g/cm3. The specific ultimate strength minimized near 0.45 mm wall thickness at 82 ± 5 MPa/g/cm3 and increased to 134 ± 3 MPa/g/cm3 at 0.6 mm wall thickness.
Originality/value
This study highlights a single lightweight metal structure, the honeycomb, built by additive manufacturing (AM). The honeycomb is an interesting structure because it is a well-known building material in the lightweight structural composites field but is still considered a relatively complex geometric shape to fabricate. As shown here, AM techniques can be used to make complex geometric shapes with strong materials to increase the design flexibility of the lightweight structural component industry.

Abstract
Purpose
This paper aims to provide a limited, but selective bibliography on modelling heat and mass transfer in composite fluid‐porous domains.
Design/methodology/approach
Since the pioneer study by Beavers and Joseph, the problem of interface continuity and/or jump conditions at a fluid‐porous interface has been of interest to the fluid mechanics and heat and mass transfer community. The paper is concerned both with numerical simulations of heat and fluid flow in such systems, and with the linear stability problems.
Findings
The one‐ and two‐domain formulations are equivalent. Using the Darcy‐Brinkman extension instead of the Darcy model reduces the number of ad hoc parameters in this configuration.
Research limitations/implications
The problem of double diffusive convection has still to be solved and analyzed.
Practical implications
The discussion on the interface conditions is of great relevance to many industrial and practical situations.
Originality/value
The important question of the macroscopic formulation of the problem is tackled in the paper.
