易门三家厂铜矿床的成矿年龄、物质来源及成因：兼论“康滇地轴“新元古代铜成矿作用与Rodinia大陆裂解的关系

引言杨子地块西部的"康滇地轴",是我国重要的铜多金属成矿带之一(冉崇英等,1990;黎功举等,1995;李朝阳等,2002),产出了拉拉、东川、易门、大红山等大型-超大型矿床.由于长期缺少高精度年代学和有效的同位素示踪数据的支持,对这些矿床的成因仍存在较大争议.本文应用40Ar-39Ar快中子活化法测定易门铜矿床矿石的形成年龄,通过矿石的Os、Sr同位素示踪成矿物质来源,进而讨论了矿床成因.并在此基础上结合前人研究成果,提出"康滇地轴"新元古代铜成矿作用可能与Rodinia大陆裂解有关。

Childhood, Rights and Justice in Northern Ireland

Building on primary research and previous publications (Haydon, 2012; Haydon, 2014; Haydon and Scraton, 2008; McAlister, Scraton and Haydon, 2009; Scraton and Haydon, 2002), this chapter will provide a critical analysis of children’s rights and youth justice in Northern Ireland. More broadly, it will consider recent research concerning the criminalisation of children and young people in the United Kingdom and profound concerns regarding the policing and regulation of children raised in successive concluding observations about the UK Government’s implementation of the UN Convention on the Rights of the Child (UN Committee on the Rights of the Child, 1995, 2002, 2008). From this generic context, the chapter will map the ‘particular circumstances’ of Northern Ireland - a discrete legal jurisdiction to which powers for justice and policing were devolved only in 2010. Emerging from four decades of conflict and progressing through an uneasy ‘peace’, rights-based institutions and enabling legislation have, in principle, promoted and protected human rights. Yet children and young people living in communities marginalised by poverty and the legacy of conflict continue to experience inconsistent formal regulation by the police and the criminal justice system, while enduring often brutal informal regulation by paramilitaries. The chapter will explore evident tensions between the dynamics of criminalisation and promotion/ protection of children’s rights in a society transitioning from conflict. Further, it will analyse the challenges to securing children’s rights principles and provisions within a hostile political and ideological context, arguing for a critical rights-based agenda that promotes social justice through rights compliance together with policies and practices that address the structural inequalities faced by children and young people.

Understanding the polyvocality of autism discourse : a critical autoethnographic approach

Currently, much of the autism literature supports the notion that Pervasive Developmental Disorder (PDD) is a deviation from what is considered "normal" and, accordingly, that it is in need of early remediation. This thesis explored alternative constructions of autism and pathology by drawing on theorists from other disciplines, such as cultural studies (Deleuze & Guattari, 1987, 1965, 1972, 1975,1980, 2003), critical psychology (Parker, 1995, 2002, 2005, 2007), disability studies (Danforth,1997, 1999, 2000; Skrtic, 1995, 1996) and anti-psychiatry (Basaglia, 1987). In an attempt to show how our accounts of the world encompass constructions rooted in language and our own histories of thinking about topics that interest us, this research took an autoethnographic approach to understanding autism discourse. Instead of denying the researcher's existence and personal investment in the research, the author attempted to implicate "the self in the research by acknowledging her own assumptions, biases and ideologies about autism discourse and practice. Thus, tensions between the self and other, personal and political become woven into the fabric, creating a personal, subjective, and partial account of the phenomenon. This research was intended to explicate and interrogate some of the taken-for-granted Truths which guide our practices with people with autism. This alternative critical framework focused on understanding autism as a discourse and explored the way these dominant autism constructions function in society. Furthermore, positioning "the self in the research was meant to illustrate the fundamental need for self-reflective practice in the social sciences.

Part Time University Teaching in Ontario: A Self-Study

This qualitative self-study explored the disappointment I felt as a part-time university teacher in a mid-sized, primarily undergraduate Ontario university, where I experienced difficulty integrating my beliefs about teaching into my practice of teaching. The purpose of this qualitative study was to inquire into why it was difficult for me, representative of a part-time university teacher in a mid-sized, primarily undergraduate university, to enact the critical pedagogical practices I espoused in my teaching philosophy. The secondary purpose was to apply the findings of the study to reframe my university teaching practice in a way that met my need to enact my beliefs about university teaching while complying with the broader geo-political conditions of part-time university teaching in Ontario (Loughran, 2006; Russell & Loughran, 2007). This study is grounded in the sociological theoretical framework of critical pedagogy (Freire, 1970; Giroux, 1988, 2010; McLaren, 2003) and the methodological framework of The Self-Study of Teacher Education Practices (S-STEP). This study combined the methods of Brookfield’s (1995; 2002) critically reflective practice and Cole and Knowles (2000) practice of reflexive inquiry with Creswell’s (2005) methods of thematic analysis to answer the research question: Why is it difficult for me to enact my beliefs about university teaching as a part-time teacher in an Ontario university? Findings suggest the geo-political contexts of part-time university teaching work can impact a teacher’s ability to enact his/her beliefs about teaching within his/her practice of teaching.

AST-120 (spherical carbon adsorbent) lowers ammonia levels and attenuates brain edema in bile duct-ligated rats

The pathogenesis of hepatic encephalopathy is multifactorial, involving gut-derived toxins such as ammonia, which has been demonstrated to induce oxidative stress. Therefore, a primary hepatic encephalopathy treatment target is reducing ammonia production in the gastrointestinal tract. AST-120, an oral adsorbent of engineered activated carbon microspheres with surface areas exceeding 1600 m(2) /g, acts as a sink for neurotoxins and hepatotoxins present in the gut. We evaluated the capacity of AST-120 to adsorb ammonia in vitro and to lower blood ammonia, oxidative stress and brain edema in cirrhotic rats. Cirrhosis was induced in rats by bile duct ligation for 6 weeks. AST-120 was administered by gavage preventively for 6 weeks (0.1, 1, and 4 g/kg/day). In addition, AST-120 was evaluated as a short-term treatment for 2 weeks and 3 days (1 g/kg/day) and as a sink to adsorb intravenously infused ammonium acetate. In vitro, AST-120 efficiently adsorbed ammonia. Ammonia levels significantly decreased in a dose-dependent manner for all AST-120-treated bile duct-ligated rats (nontreated: 177.3 ± 30.8 μM; AST-120, 0.1 g/kg/day: 121.9 ± 13.8 μM; AST-120, 1 g/kg/day: 80.9 ± 30.0 μM; AST-120, 4 g/kg/day: 48.8 ± 19.6 μM) and significantly correlated with doses of AST-120 (r = -0.6603). Brain water content and locomotor activity normalized after AST-120 treatments, whereas arterial reactive oxygen species levels remained unchanged. Furthermore, AST-120 significantly attenuated a rise in arterial ammonia after ammonium acetate administration (intravenously). Conclusion:AST-120 treatment decreased arterial ammonia levels, normalized brain water content and locomotor activity but did not demonstrate an effect on systemic oxidative stress. Also, AST-120 acts as an ammonia sink, efficiently removing blood-derived ammonia. Additional studies are warranted to evaluate the effects of AST-120 on hepatic encephalopathy in patients with advanced liver disease. (HEPATOLOGY 2011;).
