Disabled access and heritage attractions

In a UK context, the importance of heritage tourism, the potential of the disabled market, and government policies concerning tourism, social inclusion, and the historic environment provide the setting within which access improvements at heritage attractions for disabled visitors are studied. At issue is how disabled access and conservation can be reconciled. The stakeholders range from the central actors, the disabled tourists and the heritage tourism service providers, through to the gatekeeper and lobby players in the conservation, disability, and tourism contexts. The critical power structures are identified. Changes to the historic environment are managed through the conservation planning system in which disability interests are not formally represented. Recent disability discrimination legislation has not altered this balance of power, and is a source of uncertainty over the access standards that should apply to heritage attractions. An evaluation of progress in implementing access improvements at heritage attractions reveals the limited extent of improvements undertaken to date. Consideration is given not only to physical access but also to alternative methods (intellectual access) of providing the heritage tourism service. In conclusion, the situation is examined from three perspectives. From the disabled tourists' perspective, choice of heritage attractions to visit remains restricted compared to that of nondisabled tourists. The lack of consultation with disabled stakeholders in the access improvements decision-making process is discussed, including the acceptability of alternative methods of service delivery to disabled tourists. The uncertainties facing heritage tourism service providers arising from the disability discrimination legislation are considered but, to ensure a more balanced recognition of disability interests, both conservation planning and disability discrimination legislation need to be amended, adjusting the roles of the legislative gatekeepers.

Access to historic environments for tourists with disabilities: a compromise?

Historic environments, the basis for heritage tourism, are difficult to access for people with disabilities. Many countries have introduced legislation to promote equal rights for people with disabilities. Historic environments, however, enjoy protection under national planning systems which limit the physical access improvements that can be made. The significance of historic environments for tourism in the UK is outlined. Barriers restricting tourists with disabilities accessing historic sites are reviewed from the heritage tourism service provider's viewpoint. Interests of the major stakeholders are considered in terms of the apparent conflict between conservation and access issues as heritage tourism service providers seek to comply with disability discrimination legislation. From a study of access improvements made by major heritage tourism service providers, good practice is identified. However, physical access improvements to enable tourists with disabilities to visit historic environments are a compromise because of the strength of conservation interests. Questions remain as to whether this compromise is acceptable to the tourist with disabilities and whether intellectual access is an acceptable substitute for physical presence.

Promoting inclusion: facilitating access to the Silchester 'town life' project

It is becoming increasingly difficult to resource field archaeology outside the developer-funded context. Consequently it is difficult to engage the wider public in understanding the nature of archaeology and in the writing of its history from the study of material and environmental evidence. This paper describes a project funded by the UK's Heritage Lottery Fund designed to increase access by several means to a well-established and long-running archaeological excavation at the Iron Age and Roman Town at Silchester, Hampshire (UK).

Enantioselective Intramolecular Michael Addition of Nitronates onto Conjugated Esters: Access to Cyclic γ-Amino Acids with up to Three Stereocenters

A highly stereoselective synthesis of conformationally constrained cyclic γ-amino acids has been devised. The key step involves an intramolecular cyclization of a nitronate onto a conjugated ester, promoted by a bifunctional thiourea catalyst. This methodology has been successfully applied to generate a variety of γ-amino acids, including some containing three contiguous stereocenters, with very high diastereoselectivity and excellent enantioselectivity. It is postulated that an interaction that is key to the success of the process is the simultaneous coordination of the thiourea functionality to both the conjugated ester and the nitronate. Finally, the synthetic utility of these compounds is demonstrated in the synthesis of two dipeptides derived from the C- and N-termini.

Access, equity and the role of rights in health care

Modern health care rhetoric promotes choice and individual patient rights as dominant values. Yet we also accept that in any regime constrained by finite resources, difficult choices between patients are inevitable. How can we balance rights to liberty, on the one hand, with equity in the allocation of scarce resources on the other? For example, the duty of health authorities to allocate resources is a duty owed to the community as a whole, rather than to specific individuals. Macro-duties of this nature are founded on the notion of equity and fairness amongst individuals rather than personal liberty. They presume that if hard choices have to be made, they will be resolved according to fair and consistent principles which treat equal cases equally, and unequal cases unequally. In this paper, we argue for greater clarity and candour in the health care rights debate. With this in mind, we discuss (1) private and public rights, (2) negative and positive rights, (3) procedural and substantive rights, (4) sustainable health care rights and (5) the New Zealand booking system for prioritising access to elective services. This system aims to consider: individual need and ability to benefit alongside the resources made available to elective health services in an attempt to give the principles of equity practical effect. We describe a continuum on which the merits of those, sometimes competing, values-liberty and equity-can be evaluated and assessed.

Double coupling reactions of 3,4-bis(stannyl)furanone: facile preparation of diaryl- and dibenzylfuranones

The palladium-catalyzed cross-coupling reaction of 3,4-bis(tributylstannyl)furan-2(5H)-one using chelating ligand or polar solvent gives mixtures of single and double coupled products, even when one equivalent of halide coupling partner is used. After optimization, the double coupling reaction was shown to be general, with the use of two equivalents of aryl iodides giving 3,4-disubstituted furanones, The reaction using benzyl bromides proceeds at lower temperatures than the corresponding coupling using aryl iodides, giving dibenzylfuranones. The methodology has been exemplified in a synthesis of (+/-)-hinokinin.

Facile synthesis of Cu(II) complexes of monocondensed N,N,N donor Schiff base ligands: crystal structure, spectroscopic and magnetic properties

Four new copper(II) complexes, [((CuLN3)-N-1)(2)](ClO4)(2) (1), [(CuL2 N-3)(2)](ClO4)(2) (2), [CuL3(N-3)ClO4)](n) (3) and [CuL4(mu-1,1-N-3)(mu-1,3-N-3)(ClO4)](n) (4) where L-1 = N-1-pyridin-2-yl-methylene-propane-1,3-diamine, L-2 = N-1-(1-pyridin-2-yl-ethylidene)propane-1,3-diamine, L-3 =N-1-(1-pyridin-2-yl-ethylidene)ethane-1,2-diamine and L-4=N-1-(1-pyridin-2-yl-ethylidene)propane-1,2-diamine are four tridentate N,N,N donor Schiff base ligands, have been derived and structurally characterized by X-ray crystallography. Compounds 1 and 2 consist of double basal-apical end-on (EO) azide bridged dinuclear Cu-II complexes with square-pyramidal geometry. In complex 3 the square planar mononuclear [CuL3 (N-3)] units are linked by weakly coordinated perchlorate ions in the axial positions of Cu-II to form a one-dimensional chain. Two such chains are connected by hydrogen bonds involving perchlorate ions and azide groups. Compound 4 consists of 1-D chains in which the Cu-II ions with a square-pyramidal geometry are alternately bridged by single EO and end-to-end (EE) azido ligands, both adopting a basal-apical disposition. Variable temperature (300-2 K) magnetic susceptibility measurements and magnetization measurements at 2 K have been performed. The results reveal that complexes 1 and 2 are antiferromagnetically coupled through azido bridges (J= -12.18 +/- 0.09 and -4.43 +/- 0.1 cm(-1) for 1 and 2, respectively). Complex 3 shows two different magnetic interactions through the two kinds of hydrogen bonds; one is antiferromagnetic (J(1) = - 9.69 +/- 0.03 cm(-1)) and the other is ferromagnetic (J(2) = 1.00 +/- 0.01 cm(-1)). From a magnetic point of view complex 4 is a ferromagnetic dinuclear complex (J= 1.91 +/- 0.01 cm(-1)) coupled through the EO bridge only. The coupling through the EE bridge is practically nil as the N(azido)-Cu-II (axial) distance (2.643 angstrom) is too long. (C) 2006 Elsevier Ltd. All rights reserved.

A facile one step synthesis of N-2 substituted 3-phenyliminoisoindolinones from N-(2-carboxybenzoyl)-anthranilic acid and the design of reverse-turn mimetics

Stirring of N-(2-carboxybenzoyl) anthranilic acid with anilines and amines such as p-toluidine, benzylamine, methyl esters of Leu, Phe, Ile and Val in presence of DCC produces N- 2 substituted 3-phenyliminoisoindolinones in very good yields. Single crystal X-ray diffraction studies and solution phase NMR and CD studies reveal that the 3-phenyliminoisoindolinone moiety is a turn-inducing scaffold which should be useful for reverse-turn mimetics.
