Cadaveric vs. live-donor kidney transplants : theoretical foundations of interaction between institutions and inequality

In 1991, the World Health Assembly approved a set of Guiding Principles which emphasize voluntary donation, non-commercialization and a preference for cadavers over living donors” (World Health Organization). The objective of this paper is to identify the factors that affect the ratio of cadaveric transplants to all transplants. This paper first provides informational background on problems surrounding kidney transplants and then uses a theoretical framework which employs standard economic assumptions but incorporates a setup where the persons needing kidneys can obtain it from their compatible relatives or purchase it from individuals who are willing to sell one of their kidneys. The methods of economic theoretical analyses are used where following definitions and assumptions some conclusions are drawn. This paper finds that factors such as inequality, rule of law and religion have significant effect on the ratio of cadaveric transplants to all transplants. The paper concludes that improvement in equality and in rule of law will increase the use of cadaveric kidney transplants. In addition, fighting religious beliefs against cadaveric kidney transplants too will lead to a higher ratio of cadaveric transplants to all transplants.

Error analysis in translation : a case study of the Turkish-English language pair

Examines translation errors made by Turkish stream students from a three-year, full-time interpreting and translating degree course. Attempts to find out how students progress towards the curriculum objectives and how well they translate as their studies progress. The significance of errors in translation and teaching translation skills are also discussed.

Donor conception and disclosure : an anthropological study

The study, carried out within an infertility support group, concern disclosure of donor conception and its possible effects upon our constructions of conception, kinship and identity. It also examines perceptions of rights, information and its access or denial, knowledge/power, secrecy and the medicalization of reproduction.

Influence of gender and pair-type on preschool children's learning in computing context

The thesis examined early differences between girls and boys in their attitudes and social behaviour which might help explain why girls and women continue to reject computing. The behaviour of preschool children playing freely for three supervised sessions in either same-gender or mixed-gender pairs with a computerised robot was studied, and then their individual programming performance was measured. Conclusions were that social interaction and computer programming performance were not differentiated by gender. Mixed-gender pairs had a significant effect on both children's style of social interaction and their performance, an impact that was particularly negative for girls.

Donor funding of multilateral aid agencies : determining factors and revealed burden sharing

This paper reports an empirical study of the factors affecting burden sharing among OECD's 22 DAC members in 'bankrolling' the multilateral aid agencies. Annual data over 1970–2000, pooled across the donor countries, form the basis for the empirical estimation of each donor's share in the ODA aid receipts for each multilateral agency. Our findings suggest the existence of reverse exploitation, i.e., the financial burden of the agencies is disproportionally carried by the smaller donors. The study also finds that factors such as inherent donor generosity, donor concern for domestic egalitarianism, and the extent to which donors are pro-poor in their bilateral aid policies have an impact on their readiness to support multilateral agencies financially. Size of the donor government and its budgetary balance positively influence burden sharing of contributions to other multilateral agencies. But neither the phase of economic cycle nor the rate of economic growth affects the burden-sharing responsibility of donors. It was also observed that contributions by EU members to the EC do not appear to crowd-out their contributions to other multilateral aid agencies and that right-wing donor governments are generally more parsimonious with regard to financial assistance to multilateral aid agencies. The preferred alternative, particularly among EU member countries, appears to be the EC.

An analysis of side chain interactions and pair correlations within antiparallel β-sheets : the differences between backbone hydrogen-bonded and non-hydrogen-bonded residue pairs

Cross-strand pair correlations are calculated for residue pairs in antiparallel β-sheet for two cases: pairs whose backbone atoms are hydrogen bonded together (H-bonded site) and pairs which are not (non-H-bonded site). The statistics show that this distinction is important. When glycine is located on the edge of a sheet, it shows a 3:1 preference for the H-bonded site. Thestrongest observed correlations are for pairs of disulfide-bonded cystines, many of which adopt a close-packed conformation with each cystine in a spiral conformation of opposite chirality to its partner. It is likely that these pairs are a signature for the family of small, cystine-rich proteins. Most other strong positive and negative correlations involve charged and polar residues. It appears that electrostatic compatibility is the strongest factor affecting pair correlation. Significant correlations are observed for β- and γ-branched residues inthe non-H-bonded site. An examination of the structures showsa directionality in side chain packing. There is a correlation between (1) the directionality in the packing interactions of non-H-bonded β- and γ-branched residue pairs, (2) the handedness of the observed enantiomers of chiral β-branched side chains, and (3) the handedness of the twist of β-sheet. These findings have implications for the formation of β-sheets during protein folding and the mechanism by which the sheet becomes twisted

Psycho-social, ethical and legal arguments for and against the retrospective release of information about donors to donor-conceived individuals in Australia

In the February 2011 report on its inquiry into the past and present practices of donor conception in Australia, the Australian Senate Legal and Constitutional Affairs References Committee called for the introduction of legislation to regulate donor conception in all jurisdictions that do not have it in place "as a matter of priority". It further called for the establishment, "as a matter of priority", of a national register of donors to enable donor-conceived individuals to access identifying information about their donor. The Senate Committee left open the question as to whether the legislation and central register should have retrospective effect. This article focuses upon that question. It shows that arguments concerning the privacy, confidentiality and anonymity of some donors who may wish to remain anonymous are outweighed by the manifest injustice faced by donor-conceived individuals who are denied access to such information, as well as their families and donors who wish to exchange this information.

Dimerization of retroviral RNA genomes : an inseparable pair

Many viruses carry more than one segment of nucleic acid into the virion particle, but retroviruses are the only known group of viruses that contain two identical (or nearly identical) copies of the RNA genome within the virion. These RNA genomes are non-covalently joined together through a process known as genomic RNA dimerization. Uniquely, the RNA dimerization of the retroviral genome is of crucial importance for efficient retroviral replication. In this article, our current understanding of the relationship between retroviral genome conformation, dimerization and replication is reviewed.

Donor identification 'kills gamete donation'? A response

Two Australian government inquiries have recently called for the release of information to donor-conceived people about their gamete donors. A national inquiry, recommended ‘as a matter of priority’ that uniform legislation to be passed nationwide. A state-based inquiry argued that all donor-conceived people should have access to information and called for the enactment of retrospective legislation that would override donor anonymity. This paper responds to an opinion piece published in Human Reproduction in October 2012 by Professor Pennings in which he criticized such recommendations and questioned the motives of people that advocate for information release. I answer the arguments of Pennings, and argue that all parties affected by donor conception should be considered, and a compromise reached. The contact veto system is one such compromise. I discuss the education and support services recommended by the Victorian government and question Pennings' assertions that legislation enabling information release will lead to a decrease in gamete donation. Finally, I rebut Pennings' assertion that there is a ‘hidden agenda’ behind the call for information release. There is no such agenda in my work. If there is from others, then it is their discriminatory views that need to be addressed, not the move toward openness and honesty or the call for information by donor-conceived people.

Access to information about donors by donor-conceieved individuals : a human rights analysis

While assisted reproductive treatment using donated gametes is widespread, and in many places, widely accepted, it has historically been shrouded in secrecy. Over time, however, there has been an increasing call from donor-conceived people, recipient parents and some donors to end the secrecy, and to release identifying information about donors to donor-conceived people. "Rights-based" arguments have at times been used to justify this call. This article examines whether a human rights framework supports the release of information and how such a framework might be applied when there are competing rights. It argues that the current balancing approach used to resolve such issues weighs in favour of release. Legal action has the potential to be legitimate and justifiable. A measure such as a contact veto system, which would serve to prevent unwanted contact with the person lodging the veto (either the donor or the donor-conceived person), would ensure proportionality. In this way, both donor-conceived people's rights to private life, identity and family, and donors' rights to privacy may be recognised and balanced.

A hybrid contact state analysis methodology for robotic-based adjustment of cylindrical pair

The peg-in-hole insertion and adjustment operation is one of the most common tasks in the robotic and automatic assembly processes. Fine motion strategies associated with adjustment operations on a peg-in-hole are fundamental manipulations that can be utilised in dynamic assembly and reconfigurable workholding or fixturing systems. This paper presents a comprehensive study of robotic-based height adjustment of a cylindrical pair based on maintaining minimum contact forces between the links. The outer link is held by the end-effector of a six-DOF (Degrees of freedom) serial articulated robot manipulator. The environment represented by the inner link can be either static or dynamic. A force-based approach and a d value approach are established to determine the type of contact that exists between the links of a cylindrical pair, and to extract control parameters. Based on the comparison and analysis of these two approaches, a hybrid methodology is established by combining a d value approach with a force-based approach for contact state determination. Formulations capable of extracting necessary control parameters, which ensure minimum contact forces between the links, are established from both planar and spatial viewpoints under both static and dynamic environmental conditions. Experimental results demonstrate the effectiveness of the proposed methodology.
