Women's health in the global village

As we stand at the beginning of the 21st century and behold the world before us, it seems that we are living in a time of profound change. Everywhere we look change seems afoot, demolishing our traditional securities and hastily building new ones in their place. Modern medical science has been an integral part of this change. It is not possible to ignore the advances of modern medicine nor the realities of scientific uncertainties for they are part of the shared context of our lives today. I In the past 50 years we have witnessed the discovery of DNA and more recently the mapping of the human genome, the birth of the world's first in-vitro fertilisation baby, followed by thousands worldwide in the period since, the discovery of human stem cells and the birth of Dolly the cloned sheep in Scotland. Furthermore, the processes of globalisation have ensured that an event that occurs on one side of the globe becomes an item on the evening news on the other side, creating the impression that all change takes place on our doorstep. Some of these events have provoked deep angst in the community, sparking public debate over the ethics of science and the boundaries to be imposed by law. All of these developments have changed the realm of the possible. While these advances in medical science spark debate in the developed countries, in less developed countries high rates of infectious diseases and infant and maternal mortality and the challenges of access to adequate food and clean water are priorities, highlighting international differences in health care. This article explores these differences through an analysis of globalisation and reproduction. It seeks to analyse both the meaning of globalisation and the impact of globalising trends on health laws and policies as regulators of women's health within the global village.

Gearing up academics for collaborative Building Information Modelling (BIM) education

Building information modelling (BIM) radically changes the practices in architecture, engineering and construction (AEC) and creates new job opportunities. Many governments, such as the United Kingdom, have made BIM a mandatory requirement. This substantially drives the demand for a BIM-literate workforce. Universities are facing the challenge to incorporate BIM into their curricula and produce “BIM ready” graduates to meet the needs of the industry. Like other universities, Queensland University of Technology (QUT) is at the heart of this change and aspires to develop collaborative BIM education across AEC. Previous BIM education studies identify that inadequate BIM awareness of AEC academics is one of the challenges for developing a BIM curriculum and there is a dearth in the learning and teaching support for academics on BIM education. Equipping the AEC academics for a more BIM focused curriculum is all the while more important. This paper aims to leverage knowledge drawn from a Learning & Teaching project currently undertaken at QUT. Its specific objectives are to: 1) review the existing learning and teaching initiatives on BIM education; and 2) briefly describe the learning and teaching activities on collaborative BIM education at QUT. Significance of the paper lies on revealing the importance of building up the capacity of AEC academics for collaborative BIM education. The paper contributes to sparking the interests in better equipping AEC academics to understand what curriculum changes would assist in BIM uptake within the relevant courses to provide context for changes in units; and how the use of BIM can improve the understanding by students of the large amounts of professional knowledge they need to function effectively as graduates.

Can GRI light up the future of mankind?

There is strong evidence across the media that humanity has finally come to recognize the certainty and imminence of a global environmental crisis due to man-triggered ecological alterations. This widespread recognition of what is happening around us has matured even further as studies acknowledging that everything on Earth is interconnected begin to mount across various branches of learning. The appreciation of this simple linear and two-dimensional relationship implies enormous consequences for economic and management studies, as alternative business models will eventually have to supersede the old practices that still govern major industry sectors (e.g. energy, cement, agriculture, automotive, pharmaceutical, etc.). This paper argues that traditional knowledge found in developing countries can sometimes harness the potential of sparking genuine alternatives to established business practices. With a focus on the most fundamental geochemical cycles on Earth − nitrogen, water, and carbon − and the primary resources they govern (soil, water, and air), three case studies are presented to illustrate how traditional knowledge in the context of GRI (Grassroots Innovation) projects can lead to challenge the dominant logic, when allowed to thrive in terms of adoption and scalability.

Owning omega-3: Monsanto and the invention of meat

In August of 2010, Anna Salleh of the Science Unit of the Australian Broadcasting Corporation broke a story about Monsanto seeking to patent the enhancement of meat, including omega-3 fatty acids: ‘Enhanced port is sparking debate over the ethics of placing patents on food. Patent applications covering the enhancement of meat, including pork with omega-3 fatty acids, are stimulating debate over the ethics and legalities of claiming intellectual property over food. Monsanto has filed patents that cover the feeding of animals soybeans, which have been genetically modified by the company to contain stearidonic acid (SDA), a plant-derived omega-3 fatty acid... Omega-3s have been linked to improved cardiovascular health and there are many companies engineering them into foodstuffs. But the new patent applications have touched a raw nerve among those who see them as an attempt by the company to exert control over the food chain.’ This article providers a critical evaluation of the controversy of Monsanto’s patent applications, and the larger issues over patenting food. It first considers the patent portfolio of Monsanto; the nature of the patent claims; and the examination of the claims by patent examiners. Second, it examines the withdrawal and revision of the patent claims by Monsanto in the wake of criticism by patent authorities and the public disquiet over the controversial application. Third, this article considers the larger policy issues raised by Monsanto’s patent applications – including the patenting of plants, animals, and foodstuffs. There is also a consideration of the impact of patents upon the administration of health-care, competition, and research.

Ionization and breakdown in sf6-air and freon-nitrogen mixtures

The sparking potentials and swarm coefficients (ionization and attachment coefficients) have been measured in sulphurhexafluoride- air and freon-nitrogen mixtures over the range of 110 ¿ E/p ¿ 240 V cm-1 torr-l and gas pressures varying between 1 and 20 torr, at 20°C. Addition of strongly attaching salphur-hexafluoride and freon gases increased the sparking potentials and the rate of increase of the attachment coefficient with increasing percentage of the strongly attaching gases in the mixtures was much larger than the rate of change of the first ionization coefficient.

Growth of ionization currents in dry air at high values of E/N

Uniform field steady-state ionization currents were measured in dry air as a function of N at constant E/N (E is the electric field strength and N the gas number density) and constant electrode separation d for 14·13 × 10-16 less-than-or-eq, slant E/N less-than-or-eq, slant 282·5 × 10-16 V cm2. Uniform field sparking potentials were also measured for Nd range 1·24 × 1016 less-than-or-eq, slant Nd less-than-or-eq, slant 245 × 1016 cm-2. The ratio of the Townsend primary ionization coefficient α to N, α/N, was found to depend on E/N only. The secondary coefficients were also evaluated for aluminium and gold-plated electrodes for the above range of E/N. Measurements of the sparking potentials showed that Paschen's law is not obeyed in air at values of Nd near and below the Paschen minimum.

Cross-field gas breakdown in a coaxial cylinder geometry

Sparking potentials in a coaxial cylinder geometry in oxygen and dry air were measured in crossed electric and magnetic fields. From the data effective collision frequencies were calculated using the equivalent pressure concept. It is shown that the equivalent pressure concept holds good for deriving the effective collision frequencies in non-uniform electric fields.

Electrical Breakdown of Gases Between Coaxial Cylindrical Electrodes in Crossed Electric and Magnetic Fields

Sparking potentials have been measured in nitrogen and dry air between coaxial cylindrical electrodes for values of n = R2/R1 = approximately 1 to 30 (R1 = inner electrode radius, R2 = outer electrode radius) in the presence of crossed uniform magnetic fields. The magnetic flux density was varied from 0 to 3000 Gauss. It has been shown that the minimum sparking potentials in the presence of the crossed magnetic field can be evaluated on the basis of the equivalent pressure concept when the secondary ionization coefficient does not vary appreciably with B/p (B = magnetic flux density, p = gas pressure). The values of secondary ionization coefficients �¿B in nitrogen in crossed fields calculated from measured values of sparking potentials and Townsend ionization coefficients taken from the literature, have been reported. The calculated values of collision frequencies in nitrogen from minimum sparking potentials in crossed fields are found to increase with increasing B/p at constant E/pe (pe = equivalent pressure). Studies on the similarity relationship in crossed fields has shown that the similarity theorem is obeyed in dry air for both polarities of the central electrode in crossed fields.

KNOCK DETECTION ALTERNATIVES FOR PRODUCTION VEHICLES.

A method for the detection of knock using the sparking plug, and a system which allows the basic nature of the signal from the spark plug to be compared directly with that from an accelerometer are described. Results are presented for a range of engine speeds which highlight the problems and benefits of each sensing technique.

EXPERIMENTAL TECHNIQUES IN COMBUSTION USE OF IN-CYLINDER IONISATION FOR THE INVESTIGATION AND CONTROL OF SPARK IGNITION ENGINES.

Ions generated during combustion have been used in three ways to give qualitative combustion information. Langmuir type probes have been inserted into the combustion chamber opposite the spark plug location. The centre electrode of the sparking plug itself has been used to produce an ionisation signal from the slightly ionised gases remaining after the flame front has departed. The spark discharge at ignition time has been used as an anemometer.

Characteristics of anodic coatings oxidized to different voltage on AZ91D Mg alloy by micro-arc oxidization technique

With increasing applied voltage, three types of anodic coatings, passive film, micro-spark ceramic coating and spark ceramic coating were made by micro-arc oxidization (MAO) technique on AZ91D magnesium alloy in alkali-silicate solution. The structure, composition characteristics and the electrochemical properties of coatings were also studied with SEM, XRD and EIS (electrochemical impedance spectroscopy) technique, respectively. It is found that the electrochemical properties are closely related to the structure and composition characteristics of the anodic coatings. At the same time, the characteristics of the three types of anodic coatings differ significantly, among them, the micro-spark ceramic coating, prepared in the voltage range of 170similar to220V exhibits compact, homogeneous structure and highest corrosion-resistance.

States of play: Irish childhoods, race and belonging

This thesis explores the meaning-making practices of migrant and non-migrant children in relation to identities, race, belonging and childhood itself in their everyday lives and in the context of ‘normalizing’ discourses and spaces in Ireland. The relational, spatial and institutional contexts of children’s worlds are examined in the arenas of school, home, family, peer groups and consumer culture. The research develops a situated account of children’s complex subject positions, belongings and exclusions, as negotiated within discursive constructs, emerging in the ‘in-between’ spaces explored with other children and with adults. As a peripheral EU area both geographically and economically, Ireland has traditionally been a country of net emigration. This situation changed briefly in the late 1990s to early 2000s, sparking broad debate on Ireland’s perceived ‘new’ ethnic, cultural and linguistic diversity arising from the arrival of migrant people both from within and beyond the EU as workers and as asylum seekers, and drawing attention to issues of race, identity, equality and integration in Irish society. Based in a West of Ireland town where migrant children and children of migrants comprise very small minorities in classroom settings, this research engages with a particular demographic of children who have started primary school since these changes have occurred. It seeks to represent the complexities of the processes which constitute children’s subjectivities, and which also produce and reproduce race and childhood itself in this context. The role of local, national and global spaces, relational networks and discursive currents as they are experienced and negotiated by children are explored, and the significance of embodied, sensory and affective processes are integrated into the analysis. Notions of the functions and rhetorics of play and playfulness (Sutton-Smith 1997) form a central thread that runs throughout the thesis, where play is both a feature of children’s cultural worlds and a site of resistance or ‘thinking otherwise’. The study seeks to examine how children actively participate in (re)producing definitions of both childhood and race arising in local, national and global spaces, demonstrating that while contestations of the boundaries of childhood discourses are contingently successful, race tends to be strongly reiterated, clinging to bodies and places and compromising belonging. In addition, it explores how children access belongings through agentic and imaginative practices with regard to peer and family relationships, particularly highlighting constructions of home, while also illustrating practices of excluding children positioned as unintelligible, including the role of silences in such situations. Finally, drawing on teachers’ understandings and on children’s playful micro-level negotiations of race, the study argues that assumptions of childhood innocence contribute to justifying depoliticised discourses of race in the early primary school years, and also tend to silence children’s own dialogues with this issue. Central throughout the thesis is an emphasis on the productive potentials of children’s marginal positioning in processes of transgressing definitional boundaries, including the generation of post-race conceptualisations that revealed the borders of race as performative and fluid. It suggests that interrupting exclusionary raced identities in Irish primary schools requires engagement with children’s world-making practices and the multiple resources that inform their lives.

The elimination of the tutoring group-hour in Secondary Education. An exploratory study about teachers thoughts.

The Tutoring Group-hour in Compulsory Secondary Education and Post-Compulsory Schooling has been eliminated in a number of autonomous communities. Given the importance of the tutorial act as one of the fundamental pillars in students overall development, its disappearance has created considerable disturbance in the educational institutions, sparking a debate regarding the role of the tutor and the impact and effectiveness of their actions. In this survey, teachers from two different schools in the Community of Madrid maintain that they are properly trained to perform the various duties required for a tutor, show strong disagreement to the elimination of the Tutoring Group-hour in secondary schools, advocate incorporating it at a primary school level, and consider one of the main consequences of its disappearance to be less personalized attention for students. In short, an educational response that is less effective.

Towards an Emancipatory International Law: the Bolivarian reconstruction

In this article, we argue that a unique South American treaty known as ALBA—the Bolivarian Alliance for the Americas—puts forward a cohesive counter-vision of international law rooted in notions of complementarity and human solidarity. We further argue that Third World Approaches to International Law (TWAIL) scholars might use this initiative as a springboard to push forward a long-overdue reform of the international legal regime. While, on its own, ALBA is unlikely to pose much of a challenge to the structural imbalances that permeate global society, when juxtaposed alongside the many initiatives of the Bolivarian Revolution, it appears to possess signi?cant democratic potential. With both scholarly and popular support, ALBA may even have the capability of sparking a renewal of a united Third World movement.
