    Abstract A general method of increasing the ground-state total spin value of a polynuclear 3d-metal complex is illustrated through selected examples from cobalt(II) and nickel(II) cluster chemistry that involves the dianion of the gem-diol form of di-2-pyridyl ketone and carboxylate ions as organic ligands. The approach is based on the replacement of hydroxo bridges, that most often propagate antiferromagnetic exchange interactions, by the end-on azido ligand, which is a ferromagnetic coupler

    Problem drug use the public health imperative: what some of the literature says

    <p>Abstract</p> <p>Background</p> <p>With more than 200,000 problem drug users is contact with structured treatment services in England the public health imperative behind drug treatment is great. Problem drug use for many is a chronic and relapsing condition, where "cure" is often neither a reasonable or appropriate expectation and it can further be argued that in these circumstances problem drug use is no different from any number of chronic and enduring health conditions that are managed in the health care system and therefore should be conceptualised as such.</p> <p>Discussion</p> <p>A public health approach to drug treatment emphasises the need for drug users in or accessing treatment, to reduce their harmful drug use, reduce drug use related risks such as sepsis and overdose and stay alive for longer. However a public health perspective in relation to problem drug use isn't always either apparent or readily understood and to that end there is still a significant need to continue the arguments and debate that treatment and interventions for problem and dependent drug users need to extend beyond an individualistic approach. For the purposes of discussion in this article public and population health will be used interchangeably.</p> <p>Summary</p> <p>A recognition and acceptance that a public and population health approach to the management of problem drug users is sound public health policy also then requires a long term commitment in terms of staffing and resources where service delivery mirrors that of chronic condition management.</p

    Juridification, new constitutionalism and market reforms to the English NHS

    Market reforms to the English National Health Service within the neo-liberal era have diverted money away from patient needs to market bureaucracies and the coffers of private companies and undermine cross subsidy and risk pooling within the National Health Service. Consequently, governments within the neo-liberal era have sought to remove the deleterious effects of their market reforms from political contestation through strategies of depoliticisation. I assess the success of the strategies of juridification (the increase of formal law) and new constitutionalism (transnational legal rules which restrict national policymaking to the model of liberal democratic capitalism) in depoliticising market reforms to the English National Health Service. As the National Health Service was increasingly marketised, European Union public procurement and competition laws became increasingly applicable, although scope exists for exceptions. The discretion afforded to commissioners by the regulations passed pursuant to S.75 of the Health and Social Care Act (2012) regarding tendering is disputed. Many commissioners have acted as though their discretion was curtailed in practice. However, there are countervailing forces to competition, such as resource constraints and recent moves towards integration (although this may also afford private sector companies with new opportunities). I contend that the privatisation that marketisation has facilitated appears highly politicised, as is evidenced by increased campaigning activity in opposition to it. Recent responses to the Transatlantic Trade and Investment Partnership and prospective post-Brexit trade deals indicate a heightened awareness of the ability of external constitutional constraints to restrict National Health Service policymaking. This suggests that neither the strategies of juridification nor new constitutionalism have been successful in depoliticising market reforms to the English National Health Service
