敦煌石窟摩利支天曼荼罗图像解说

敦煌石窟中的摩利支天曼荼罗及其造像共有三例,即榆林窟第3窟北壁东侧、东千佛洞第5窟、莫高窟第3窟主尊造像。这些壁画或塑像是根据宋代天息灾译《佛说大摩里支菩萨经》绘制的,与公元9-10世纪印度后期密教的图像及其仪轨在印度的流行有着深刻的关系。研究结果表明,宋代天息灾等印度高僧在中原弘传密教翻译密典,不但给予中原的宋代密教以直接的影响,而且还对西夏时代的敦煌佛教产生了深远的影响。     

Awakening vision: examining the reconceptualization of Aboriginal education in Canada via Kaupapa Māori praxis

Kaupapa Māori theory was conceptualized in the 1980s in New Zealand as a framework for revolutionizing Indigenous education. Its success marks it as a transformational praxis beneficial to educators beyond the shores of Aotearoa. This theory propounds a practical, proactive stance that enables a shift in thinking away from the psychology of de-colonization towards a “conscientization” or consciousness raising which Friere says can occur when a people take action against the oppressive elements in their lives. In this paper I provide an overview of the current state of Aboriginal education in Canada, citing examples of Canadian instructors who envisage similar self-empowering pedagogy. In addition, I highlight a Canadian case study to demonstrate the process of critical consciousness underway at a First Nations school in Aklavik, NWT, where teachers are employing Kaupapa Māori theory and culture-based curriculum for positive outcomes. This focus serves as a critical lens to educators, policy makers, and other stakeholders who might want to draw more from the transformative power of the Māori framework as counter strategy to Eurocentric curricula and colonial paradigms.     

Child‐Rearing Practices and Expert Identities: A tale of two interventions

Paul Smeyers’ keynote address to the PESA 2007 Conference, ‘The Entrepreneurial Self and Informal Education: On government intervention and the discourse of experts’ provides a timely call for questioning the governing of the family. This paper draws upon Smeyers’ key concerns to explore both historical and contemporary trends in clustering government agencies, under the guidance of child development experts. The guidance of two expert groups is problematised, with particular attention to an absence of commitment to Māori perspectives of education and child‐rearing. Such an absence reflects, in New Zealand, a dangerous undermining of the historic treaty between the British and Māori. The paper then challenges, with brief reference to Jacques Derrida's discussions on autobiography and Freud's Legacy, the identity of expert groups advocating early intervention in the lives of families measured as a burden on economic and social progress. The paper posits that perhaps it is the developmental expert that requires some form of early intervention.     

Montgomery multiplication over rings

Montgomery multiplication of two elements a and b of a finite field F_q is defined as abr^-1 where r is a fixed field element in . In this paper we define Montgomery multiplication of elements a(x) and b(x) in a polynomial ring modulo the ideal generated by a reducible polynomial f(x). We then show that Montgomery multiplication over a field represented by a polynomial ring modulo an irreducible pentanomial can be performed more efficiently in terms of time delay by embedding the field in a quotient of a polynomial ring modulo a reducible trinomial. The trinomial has a degree that is slightly higher than that of the pentanomial, thereby increasing the number of gates in the multiplier by a small amount.     

Resolving the knowledge paradox: Knowledge-spillover entrepreneurship and economic growth

The knowledge paradox suggests that high levels of investment in new knowledge do not necessarily and automatically generate the anticipated levels of competitiveness of growth. In particular, knowledge investments do not automatically translate into balanced growth and competitiveness. The purpose of this paper is to explain why knowledge investments are inherently unbalanced, so that the competitiveness and growth ensuing from knowledge are not equally spread across individuals, firms, and spatial units of observation, such as regions and countries. Based on a data set linking entrepreneurial activity to growth within the context of German regions, this paper shows that entrepreneurship serves a conduit of knowledge spillovers.
