We herewith present the critical edition, translation and notes from the second commentary of Abraham ibn Ezra on the Song of Songs. This work is preceded by an introductory study that considers among others, various aspects of the commentary and the influence that the previous and contemporary Jewish exegesis to Ibn Ezra’s may exert on his interpretations of the Song of Songs. Finally, we analyze some of the features that are part of the commentary of Ibn Ezra on the Canticles. Summary: Objectives and results It is the purpose of this work to go into detail about the study of the exegetical texts of Abraham ibn Ezra, and in particular the text of this second commentary of Ibn Ezra on Song of Songs, whose translation and critical edition is the subject of this work. This is especially interesting since it is one of the few translations from the original Hebrew, among which are the Latin translation of Gilberto Genebrardo, published in Paris in 1585 and the English edition of Richard A. Block, published in 1982 in Cincinnati. This edition of the second commentary of Ibn Ezra on the Song of Songs continues the lead of previous work carried out in the translation and critical edition of Ibn Ezra's comments to Ecclesiastes, Esther, and Job by Mariano Gómez Aranda and the commentary to Book of Ruth by Maria Josefa Azcárraga Servert. The translation of Abraham ibn Ezrás text on the aforementioned second commentary on the Song of Songs, and the drawing up of the critical edition by selecting manuscripts that, once collated, will lead to the Hebrew text that will be used for the Castilian version is the basis of the present work. Of the thirty-three existing manuscripts of Ibn Ezra's commentary on the Canticles, ten have been rejected in principle since they belong to the first commentary, whose text on two manuscripts was translated into English by H. J. Mathews in 1874. Only thirteen out of the remaining twenty three manuscripts have been used for drawing up the critical edition, since ten of them have not been included in the present edition in spite of their belonging to the second commentary...

Em 1880, uma parte de uma Europa científica marca encontro em Lisboa, no XV Congresso Internacional de Antropologia e Arqueologia Pré-Histórica, coincidindo com a euforia europeia de nacionalismo, de cientismo e de colonialismo científico. Um Congresso Científico permite olhar para práticas científicas e culturais decorrentes da rede de organização de congresso científicos internacionais, como «parlamentos científicos itinerantes» que mobilizam cidades e Estados. Este focus permite convergir para uma história da ciência em áreas de interface de prática científica: diplomacia e relações internacionais; ciência, cientistas e construção de identidades exibidas e propagandeadas nos programas sociais, nas visitas de turismo, nas sessões de abertura e de encerramento ou de receções festivas. Cada um dos focus de parlamentarismo científico itinerante funcionaram também como instrumentos de construção do publico entendimento da ciência, numa clara afirmação da importância do capital científico da primeira metade do século XX!

This abstract provides a preliminary discussion of the importance of recognising Torres Strait Islander knowledges and home languages of mathematics education. It stems from a project involving Torres Strait Islander Teachers and Teacher Aides and university based researchers who are working together to enhance the mathematics learning of students from Years 4-9. A key focus of the project is that mathematics is relevant and provides students with opportunities for further education, training and employment. Veronica Arbon (2008) questions the assumptions underpinning Western mainstream education as beneficial for Aboriginal and Torres Strait Islander people which assumes that it enables them to better participate in Australian society. She asks “how de we best achieve outcomes for and with Indigenous people conducive to our cultural, physical and economic sustainability as defined by us from Indigenous knowledge positions?” (p. 118). How does a mainstream education written to English conventions provide students with the knowledge and skills to participate in daily life, if it does not recognise the cultural identity of Indigenous students as it should (Priest, 2005; cf. Schnukal, 2003)? Arbon (2008) states that this view is now brought into question with calls for both ways education where mainstream knowledge and practices is blended with Indigenous cultural knowledges of learning. This project considers as crucial that cultural knowledges and experiences of Indigenous people to be valued and respected and given the currency in the same way that non Indigenous knowledge is (Taylor, 2003) for both ways education to work.

This paper presents dynamic hysteresis band height control to reduce the overshoot and undershoot issue on output voltage caused by load change. The converters in this study are Boost and Positive Buck-Boost (PBB) converters. PBB has been controlled to work in a step up conversion and avoid overshoot when load is changed. Simulation and experimental results have been presented to verify the proposed method.

Grassroots groups – autonomous, not-for-profit groups made up of volunteers – and grassroots initiatives play an invaluable, yet often invisible, role in our communities. The informal processes and collective efforts of grassroots associations, social movements, self-help groups and local action collectives are central to civil society and community building. Grassroots leaders are critical to such initiatives, yet little is known about their influences, motivations, successes and challenges. This study aims to address this dearth in the research literature by noting the experiences of a sample of grassroots community leaders to help gain a greater knowledge about community leadership in action. In-depth semi-structured interviews were held with nine grassroots leaders from a broad cross-section of sectors of interest. The criteria for selection were that these leaders were not in a formal non-profit organisation, were not paid for their work yet were leading grassroots groups or initiatives involved in active community building, campaigning or self-help. The paper reflects on findings in regard to the formative experiences that impacted upon the community leaders’ direction in life, their beliefs and ideas about what it means to be a leader, the strategies they use to lead and challenges they continue to face, and the role of learning and support in maintaining and developing their roles. Finally, the key themes relating to grassroots leadership and how these leaders enhance their own effectiveness and resilience are explored.

Multi-output boost (MOB) converter is a novel DC-DC converter unlike the regular boost converter, has the ability to share its total output voltage and to have different series output voltage from a given duty cycle for low and high power applications. In this paper, discrete voltage control with inner hysteresis current control loop has been proposed to keep the simplicity of the control law for the double-output MOB converter, which can be implemented by a combination of analogue and logical ICs or simple microcontroller to constrain the output voltages of MOB converter at their reference voltages against variation in load or input voltage. The salient features of the proposed control strategy are simplicity of implementation and ease to extend to multiple outputs in the MOB converter. Simulation and experimental results are presented to show the validity of control strategy.

The extent of poor project outcomes is a recurring issue for construction industries worldwide. One of the main causes of these and project failure seems to be the inability of contractors to provide a high level of service quality to the project team. In Malaysia, design failures have also been identified as a further contributory factor. To overcome this, different types of subjective performance measurement have been progressively developed. These approaches are typically concerned with client satisfaction, customer satisfaction, home buyer satisfaction and occupant satisfaction, but very seldom consider contractor satisfaction. This paper examines the implications of this, and what is involved in developing satisfaction measures based on contractor perception instead of the typical sole concern with client performance. As a result, other attributes such as participants’ performance, business performance, project performance, external factors and contractor characteristics are also examined. Several potential attributes are derived from interviews among Malaysian contractors, namely: performance (direct attributes) and contractor characteristics (indirect attributes) that possibly influence contractor satisfaction levels. These attributes are then developed to improve the existing conceptual framework. The developed framework is expected to help the project team in performing projects more efficiently, maintaining service quality and improving relationships between participants. In addition, the findings of the paper should assist contractors enhance competitiveness, improve their image and create more job opportunities in the future.

The development of autonomous air vehicles can be an expensive research pursuit. To alleviate some of the financial burden of this process, we have constructed a system consisting of four winches each attached to a central pod (the simulated air vehicle) via cables - a cable-array robot. The system is capable of precisely controlling the three dimensional position of the pod allowing effective testing of sensing and control strategies before experimentation on a free-flying vehicle. In this paper, we present a brief overview of the system and provide a practical control strategy for such a system. ©2005 IEEE.
