Characterization of heterogeneity and spatial distribution of phases in complex solid dispersions by thermal analysis by structural characterization and X-ray micro computed tomography
Purpose: This study investigated the effect of drug-excipient miscibility on the heterogeneity and spatial distribution of phase separation in pharmaceutical solid dispersions at a micron-scale using two novel and complementary characterization techniques, thermal analysis by structural characterization (TASC) and X-ray micro-computed tomography (XCT) in conjunction with conventional characterization methods. Method: Complex dispersions containing felodipine, TPGS, PEG and PEO were prepared using hot melt extrusion-injection moulding. The phase separation behavior of the samples was characterized using TASC and XCT in conjunction with conventional thermal, microscopic and spectroscopic techniques. The in vitro drug release study was performed to demonstrate the impact of phase separation on dissolution of the dispersions. Results: The conventional characterization results indicated the phase separating nature of the carrier materials in the patches and the presence of crystalline drug in the patches with the highest drug loading (30% w/w). TASC and XCT where used to provide insight into the spatial configuration of the separate phases. TASC enabled assessment of the increased heterogeneity of the dispersions with increasing the drug loading. XCT allowed the visualization of the accumulation of phase separated (crystalline) drug clusters at the interface of air pockets in the patches with highest drug loading which led to poor dissolution performance. Semi-quantitative assessment of the phase separated drug clusters in the patches were attempted using XCT. Conclusion: TASC and XÎŒCT can provide unique information regarding the phase separation behavior of solid dispersions which can be closely associated with important product quality indicators such as heterogeneity and microstructure
âRepeal the 8thâ in a Transnational Context: The Potential of SRHRs for Advancing Abortion Access in El Salvador
This article undertakes a discursive feminist reading of citizenship and human rights to understand, through the cases of Ireland and El Salvador, domestic abortion rights movements as part of a transnational womenâs rights movement. While abortion has been partially decriminalised in Ireland, approximately 42 per cent of the worldâs women1 of reproductive age still live in a country where abortion is prohibited entirely or only permitted to save a womanâs life or health (Singh et al., 2018, p. 4). In El Salvador, abortion is illegal and those suspected of having the procedure are prosecuted. As in Ireland, since 2012/2013 numerous controversies have brought the issue to wider public attention and have further galvanised the feminist movement to campaign for reform. Feminist abortion rights campaigns in both countries have connected important sites of activism and contestation: civil society, national parliaments, regional human rights systems and the United Nations

Community-based assessment of human rights in a complex humanitarian emergency: the Emergency Assistance Teams-Burma and Cyclone Nargis
<p>Abstract</p> <p>Introduction</p> <p>Cyclone Nargis hit Burma on May 2, 2008, killing over 138,000 and affecting at least 2.4 million people. The Burmese military junta, the State Peace and Development Council (SPDC), initially blocked international aid to storm victims, forcing community-based organizations such as the Emergency Assistance Teams-Burma (EAT) to fill the void, helping with cyclone relief and long-term reconstruction. Recognizing the need for independent monitoring of the human rights situation in cyclone-affected areas, particularly given censorship over storm relief coverage, EAT initiated such documentation efforts.</p> <p>Methods</p> <p>A human rights investigation was conducted to document selected human rights abuses that had initially been reported to volunteers providing relief services in cyclone affected areas. Using participatory research methods and qualitative, semi-structured interviews, EAT volunteers collected 103 testimonies from August 2008 to June 2009; 42 from relief workers and 61 from storm survivors.</p> <p>Results</p> <p>One year after the storm, basic necessities such as food, potable water, and shelter remained insufficient for many, a situation exacerbated by lack of support to help rebuild livelihoods and worsening household debt. This precluded many survivors from being able to access healthcare services, which were inadequate even before Cyclone Nargis. Aid efforts continued to be met with government restrictions and harassment, and relief workers continued to face threats and fear of arrest. Abuses, including land confiscation and misappropriation of aid, were reported during reconstruction, and tight government control over communication and information exchange continued.</p> <p>Conclusions</p> <p>Basic needs of many cyclone survivors in the Irrawaddy Delta remained unmet over a year following Cyclone Nargis. Official impediments to delivery of aid to storm survivors continued, including human rights abrogations experienced by civilians during reconstruction efforts. Such issues remain unaddressed in official assessments conducted in partnership with the SPDC. Private, community-based relief organizations like EAT are well positioned and able to independently assess human rights conditions in response to complex humanitarian emergencies such as Cyclone Nargis; efforts of this nature must be encouraged, particularly in settings where human rights abuses have been documented and censorship is widespread.</p
Is the deinstitutionalisation of alternative care a âwicked problemâ? A qualitative study exploring the perceptions of child welfare practitioners and policy actors in Thailand
This study examined deinstitutionalisation in Thailand. Qualitative interviews were conducted with a total of 27 child welfare practitioners and policy actors to explore their perceptions of Thai alternative care provision. Findings show that participants perceive deinstitutionalisation as a complex policy challenge. Some felt that the institutions were necessary in order to meet demand, while others felt that cultural barriers prevent a shift to family-based approaches, such as foster care. However, data suggest that it would be difficult to characterise deinstitutionalisation as a âwicked policy problemâ as participants were hopeful for change, citing increased family- strengthening policies alongside efforts to implement foster care
Collateral damage? Small-scale fisheries in the global fight against IUU fishing
© 2020 The Authors. Fish and Fisheries published by John Wiley & Sons Ltd Concern over illegal, unreported and unregulated (IUU) fishing has led to a number of policy, trade and surveillance measures. While much attention has been given to the impact of IUU regulation on industrial fleets, recognition of the distinct impacts on small-scale fisheries is conspicuously lacking from the policy and research debate. In this paper, we outline three ways in which the application of IUU discourse and regulation undermines small-scale fisheries. First, the mainstream construction of âillegal,â âunreportedâ and âunregulatedâ fishing, and also the categorical use of âIUUâ in an all-inclusive sense, disregards the diversity, legitimacy and sustainability of small-scale fisheries practices and their governing systems. Second, we explore how the recent trade-related measures to counter IUU fishing mask and reinforce existing inequalities between different sectors and countries, creating an unfair burden on small-scale fisheries and countries who depend on them. Third, as IUU fishing is increasingly approached as âorganized crime,â there is a risk of inappropriately targeting small-scale fisheries, at times violently. Reflecting on these three trends, we propose three strategies by which a more sensitive and ultimately more equitable incorporation of small-scale fisheries can be supported in the global fight against IUU fishing
