A rich source of Japanese jurisprudence on sexual equality underlies Japan's emerging law against sexual harassment. With no law specifically outlawing sexual harassment, academics and the courts have invoked the principle of sexual equality to support their conclusion that Japanese law carries an implicit prohibition against acts of sexual harassment. In developing a legal case against sexual harassment, Japanese courts and academic commentators have introduced novel constructions of equality. The key innovations include relational equality, inherent equality and quantifiable equality. In presenting some of these Japanese contributions to equality jurisprudence, the hope is that feminist discourse on equality can take place in a broader context-a context that does not ignore the Eastern cultural experience.

Raw data from SeaScan™ transects off Wide Bay (south Queensland) taken in August 2007 as part of a study of ecological factors influencing the distribution of spanner crabs (Ranina ranina). The dataset (comma-delimited ascii file) comprises the following fields: 1. record number 2. date-time (GMT) 3. date-time (AEST) 4. latitude (signed decimal degrees) 5. longitude (decimal degrees) 6. speed over ground (knots) 7. depth (m) 8. seabed roughness (v) 9. hardness (v) Indices of roughness and hardness (from the first and second echoes respectively) were obtained using a SeaScan™ 100 system (un-referenced) on board the Research Vessel Tom Marshall, with the ship’s Furuno FCV 1100 echo sounder and 1 kW, 50 kHz transducer. Generally vessel speed was kept below about 14 kt (typically ~12 kt), and the echo-sounder range set to 80 m. The data were filtered to remove errors due to data drop-out, straying beyond system depth limits (min. 10 m), or transducer interference.

Effective and targeted conservation action requires detailed information about species, their distribution, systematics and ecology as well as the distribution of threat processes which affect them. Knowledge of reptilian diversity remains surprisingly disparate, and innovative means of gaining rapid insight into the status of reptiles are needed in order to highlight urgent conservation cases and inform environmental policy with appropriate biodiversity information in a timely manner. We present the first ever global analysis of extinction risk in reptiles, based on a random representative sample of 1500 species (16% of all currently known species). To our knowledge, our results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles. Nearly one in five reptilian species are threatened with extinction, with another one in five species classed as Data Deficient. The proportion of threatened reptile species is highest in freshwater environments, tropical regions and on oceanic islands, while data deficiency was highest in tropical areas, such as Central Africa and Southeast Asia, and among fossorial reptiles. Our results emphasise the need for research attention to be focussed on tropical areas which are experiencing the most dramatic rates of habitat loss, on fossorial reptiles for which there is a chronic lack of data, and on certain taxa such as snakes for which extinction risk may currently be underestimated due to lack of population information. Conservation actions specifically need to mitigate the effects of human-induced habitat loss and harvesting, which are the predominant threats to reptiles.

Monocotyledonous plant infecting mastreviruses (family Geminiviridae) have been found in the Old World. The greatest diversity of these viruses has been found in Africa but this may simply reflect the more extensive sampling that has been done there. To provide a better understanding of mastrevirus diversity in Australia. we have sequenced the genomes of 41 virus isolates found in naturalised and native grasses and identified four new species in addition to the four previously characterised species. Two of these species, which were recovered from a single Sporobolus plant, are highly divergent and are most closely related to the African streak viruses. This, coupled with the discovery of divergent dicotyledonous plant infecting mastreviruses in Australia brings into question the hypothesis that mastreviruses may have originated in Africa. We found that the patterns of inter- and intra-species recombination and the recombination hotspots mirror those found in both their African monocot-infecting counterparts and dicot-infecting mastrevirus.

Sea water electrolysis is one of the promising ways to produce hydrogen since it is available in plentiful supply on the earth. However, in sea water electrolysis toxic chlorine evolution is the preferred reaction over oxygen evolution at the anode. In this work, research has been focused on the development of electrode materials with a high selectivity for oxygen evolution over chlorine evolution. Selective oxidation in sea water electrolysis has been demonstrated by using a cation-selective polymer. We have used a perm-selective membrane (Nafion®), which electrostatically repels chloride ions (Cl−) to the electrode surface and thereby enhances oxygen evolution at the anode. The efficiency and behaviour of the electrode have been characterized by means of anode current efficiency and polarization studies. The surface morphology of the electrode has been characterized by using a scanning electron microscope (SEM). The results suggest that nearly 100% oxygen evolution efficiency could be achieved when using an IrO2/Ti electrode surface-modified by a perm-selective polymer.

The collection contains correspondence among members of the Ehrenberg and Rosenzweig families, including letters from Franz Rosenzweig, Adam Rosenzweig and Richard Ehrenberg, as well as with other parties, including Leopold Zunz, Adelheid Zunz, Claire von Gluemer, and Heinrich Heine (copies only). Also included are engagement contracts, marriage banns, school curricula and certificates, character references, eulogies, family histories, and other documents concerning family members. This material also reflects much of the history of the Samsonschule in Wolfenbuettel of which members of the Ehrenberg family were principals.

We have developed a totally new class of nonporphyrin photodynamic therapeutic agents with a specific focus on two lead candidates azadipyrromethene (ADPM)01 and ADPM06. Confocal laser scanning microscopy imaging showed that these compounds are exclusively localised to the cytosolic compartment, with specific accumulation in the endoplasmic reticulum and to a lesser extent in the mitochondria. Light-induced toxicity assays, carried out over a broad range of human tumour cell lines, displayed EC50 values in the micro-molar range for ADPM01 and nano-molar range for ADPM06, with no discernable activity bias for a specific cell type. Strikingly, the more active agent, ADPM06, even retained significant activity under hypoxic conditions. Both photosensitisers showed low to nondeterminable dark toxicity. Flow cytometric analysis revealed that ADPM01 and ADPM06 were highly effective at inducing apoptosis as a mode of cell death. The photophysical and biological characteristics of these PDT agents suggest that they have potential for the development of new anticancer therapeutics. © 2005 Cancer Research UK.
