Pathways to Parenting in New Zealand: Issues in Law, Policy and Practice

In New Zealand there are many ways to become a parent, including two-parent families of heterosexual and homosexual couples, single parents, adoptive parents, kin carers, wha ̄ngai arrangements, long-term fostering, guardianship and assisted reproductive technologies. In this paper we discuss the different pathways to parenthood, how they have come about, and New Zealand’s laws, policies and practices that make them possible but also challenging. Two areas of law of particular interest are the implications of the Adoption Act 1955, which continues to be discriminatory, although some of its provisions have been reinterpreted in the courts, and the Care of Children Act 2004, which introduced ‘modern’ parenting arrangements but allowed conflicts to remain with previous child care Acts. The new Home for Life policy introduced by the Ministry of Social Development will also be critically discussed, in light of its weaknesses. We conclude with implications of the varied pathways and identified gaps in our current knowledge that call for further research

Global Commercial Surrogacy and International Adoption: Parallels and Differences

Over the decades, there have been numerous trends in the formation of family for those experiencing infertility. Adoption – initially domestic but now mostly international – has long been a prevailing method, with a dual outcome of also finding homes for parentless children. Those would-be parents with a stronger desire for genetic relatedness have turned to assisted reproductive technologies for the creation of their families. In the 21st century, capitalising on globalisation and advances in medical sciences and communication, global commercial surrogacy (GCS) is emerging as a dominant method of family formation. In seeking to publish this article in Adoption & Fostering, our primary objective was to provide its readership with an introductory look at GCS, thereby expanding an awareness of surrogacy to an audience whose work has traditionally been concerned with the care and protection of children through foster care and adoption. A secondary aim was to see where the long-standing field of adoption could potentially inform the burgeoning field of global commercial surrogacy. To achieve these objectives, we use international adoption and the adoption triangle as a framework, as we look at the similarities and differences between: (1) the adoptive and commissioning parents; (2) the birth mother and the surrogate; and (3) the adopted children and the children born of global surrogacy

Cucurbit[8]uril-Regulated Nanopatterning of Binary Polymer Brushes via Colloidal Templating.

Sub-micrometer/nanoscale patterned polymer brushes are prepared by employing cucurbit[8]uril (CB[8]) as a supramolecular recognition motif to assemble functional silica colloids onto Au surfaces as a sacrificial nanopatterning template. By employing CB[8]-mediated host-guest interactions at the interface, it is possible to readily generate nanopatterned materials in aqueous media under ambient conditions.This work was supported by the Engineering Physical Science Research Council, grant EP/K028510/1; C.H. thanks BP for financial support and Y.L. is grateful for a CSC Cambridge Scholarship.This is the author accepted manuscript.

Modulating stiffness with photo-switchable supramolecular hydrogels

Stimuli-responsive hydrogels are attractive materials with many applications towards biomedicine,biology, construction, and manufacturing. Materials that can be cured or annealed rapidly at room temperature are of particular interest. In this work we develop a class of supramolecular coumarin-functionalised hydrogels formedviahost-guest mediated self-assembly with cucurbit[8]uril thatcan photo-switch to covalent gels and reversibly toggle between the two states. A principle ad-vantage of such materials is their ability to maintain a homogeneous chemical composition and crosslink density while selectively modulating stiffness with light. An investigation of the photo-reversibility of these functional materials elucidated that hydroxyethyl cellulose-coumarin based gels were soft and could only switch from a physical state to a covalent one, while hyaluronic acid-coumarin based gels were softer and could be photo-reversed back into a physical state after covalent curing.A.T. acknowledges The Winston Churchill Foundation of the United States.

A novel thiazolidine compound induces caspase-9 dependent apoptosis in cancer cells

Cataloged from PDF version of article.The forward chemogenomics strategy allowed us to identify a potent cytotoxic thiazolidine compound as an apoptosis-inducing agent. Chemical structures were designed around a thiazolidine ring, a structure already noted for its anticancer properties. Initially, we evaluated these novel compounds on liver, breast, colon and endometrial cancer cell lines. The compound 3 (ALC67) showed the strongest cytotoxic activity (IC50 ∼5 μM). Cell cycle analysis with ALC67 on liver cells revealed SubG1/G1 arrest bearing apoptosis. Furthermore we demonstrated that cytotoxicity of this compound was due to the activation of caspase-9 involved apoptotic pathway, which is death receptor independent. © 2012 Elsevier Ltd.

Cucurbit[8]uril-Regulated Colloidal Dispersions Exhibiting Photocontrolled Rheological Behavior.

In situ photocontrol over shear-thickening of condensed colloidal dispersions is of paramount importance in a wide range of applications including process technology and photorheological fluids. Its development and practicability, however, are hampered by the lack of well-designed photoresponsive systems. Here, a colloidal suspension whose rheological behavior is readily switchable between shear-thinning and shear-thickening using an external light stimulus is reported. This smart colloidal solution contains hybrid raspberry-like colloids prepared by employing cucurbit[8]uril as a supramolecular linker to assemble functional Fe3 O4 nanoparticles onto a silica core. The formed raspberry colloids are photoresponsive and can be reversibly disassembled under UV irradiation

Eliminating irreproducibility in SERS substrates

Irreproducibility in surface-enhanced Raman spectroscopy (SERS) due to variability among substrates is a source of recurrent debate within the field. It is regarded as a major hurdle towards the widespread adoption of SERS as a sensing platform. Most of the literature focused on developing substrates for various applications considers reproducibility of lower importance. Here, we address and analyse the sources of this irreproducibility in order to show how these can be minimised. We apply our findings to a simple substrate demonstrating reproducible SERS measurements with relative standard deviations well below 1% between different batches and days. Identifying the sources of irreproducibility and understanding how to reduce these can aid in the transition of SERS from the lab to real world applications.Isaac Newton Trust Leverhulme Trust Winton Programme for the Physics of Sustainability Trinity College, University of Cambridg

The Perceptions of New Zealand Lawyers and Social Workers about Children Being Adopted by Gay Couples and Lesbian Couples

Global trends increasingly appear to be legitimising same-gender relationships, yet international research shows that despite statutory rights to marry—and by extension, adopt children—same-gender couples continue to experience difficulties when trying to adopt. Primary among these barriers are the persistent heteronormative beliefs, which strongly underpin the unfounded myths about parenting abilities of same-gender couples. Such biased beliefs are perpetuated by some adoption professionals who oppose placing children with lesbian or gay couples. In 2013, New Zealand passed the Marriage Equality Act, making it possible for same-gender couples to legally marry—and by extension, adopt. This provided an opportunity to investigate the perceptions of New Zealand professionals about children being placed with same-gender couples, in a country often perceived to be more tolerant of LGBT people. New Zealand social workers and lawyers (an under-studied group)—the professions most likely involved in adoption—were recruited via professional bodies. Because studying perceptions and beliefs on socially sensitive topics are highly susceptible to social desirability, we designed an instrument utilizing multiple methods to assess and corroborate participants’ views about placing children for adoption with couples of the same gender. Administered online and anonymously, the survey included demographic questions, evaluation of negative-meaning and positive-meaning statements, and used a scenario describing a prospective adoptive couple whose gender was ambiguous, in the context of adopting children of varying needs. Overall, the study found that while New Zealand lawyers and social workers (N=314) had generally favourable views of gay and lesbian adoption, they still reported a preference to see children adopted by heterosexual couples over same-gender couples, within which lesbian and gay couples were preferred equally. Moreover, being religious and politically conservative were characteristics associated with more negative views toward placing children with same-gender couples. We conclude that, despite winning the rights to marry (and adopt as couples), such legislative wins might be merely the first hurdle to be overcome; normalising same-gender parenting is what needs to happen next. Our study adds to the research focused on adoption professionals in various countries, with the ultimate aim to inform practices and policies supportive of families headed by same-gender couples and formed through adoption

Cell geometry across the ring structure of Sitka spruce.

For wood to be used to its full potential as an engineering material, it is necessary to quantify links between its cell geometry and the properties it exhibits at bulk scale. Doing so will make it possible to predict timber properties crucial to engineering, such as mechanical strength and stiffness, and the resistance to fluid flow, and to inform strategies to improve those properties as required, as well as to measure the effects of interventions such as genetic manipulation and chemical modification. Strength, stiffness and permeability of timber all derive from the geometry of its cells, and yet current practice is to predict them based on properties, such as bulk density, that do not directly describe the cell structure. This work explores links between micro-computed tomography data for structural-size pieces of wood, which show the variation of porosity across the wood's ring structure, and high-resolution tomography showing the geometry of the cells, from which we measure cell length, lumen area, porosity, cell wall thickness and the number density of cells. High-resolution scans, while informative, are time-consuming and expensive to run on a large number of samples at the scale of building components. By scanning the same volume of timber at both low and high resolutions (high-resolution scans over a near-continuous volume of timber of approx. 20 mm3 at 15 μm3 per voxel), we are able to demonstrate correlations between the measurements at the two different resolutions, reveal the physical basis for these correlations, and demonstrate that the data from the low-resolution scan can be used to estimate the variation in (small-scale) cell geometry throughout a structural-size piece of wood.This work was funded in major part by a Leverhulme Trust Programme Grant.
