title: Synthesis and characterisation of four- and eight-membered ring auralactam complexes

authors: Henderson, William

subjects: Gold

abstract: The reactions of the cyclo-aurated gold(III) dihalide complex [{C6H3 (CH2NMe2)-2-(OMe)-5}AuCl2] with N-cyanoacetylurethane [NCCH2C(O)NHCO2Et], 2-benzoylacetanilide [PhC(O)CH2C(O)NHPh] and acetoacetanilide [MeC(O)CH2C(O)NHPh], and [{C6H4 (CH2NMe2)-2}AuCl2] with acetoacetanilide in dichloromethane with excess silver(I) oxide gives the first examples of auralactam complexes, containing Au-NR-C(O)-CHR′ four-membered rings. A single-crystal X-ray diffraction study on the complex [{C6H4 (CH2NMe2)-2}Au{NPhC(O)CH(COMe)}] reveals similar structural features to related metallalactam complexes of platinum(II) and palladium(II). When a CDCl3 solution of the complex [{C6H3 (CH2NMe2)-2-(OMe)-5}Au{N(CO2Et)C(O)CHCN}] is allowed to stand for 18 h, a novel dimerisation reaction occurs, giving the insoluble product [{C6H3 (CH2NMe2)-2-(OMe) 5}Au{N(CO2Et)C(O)CHCN}]2 2CDCl3, characterised by an X-ray structure determination. The dimer contains an eight-membered Au-N-C(O)-C-Au-N-C(O)-C ring.

title: Cyber- space, law and diplomacy

authors: Dizon, Michael

abstract: Indicative questions for discussion:
How does international law intersect with cyber diplomacy? How does the legal community see cyber diplomacy and how are they involved in it?What are the latest developments in diplomatic efforts to apply international law to cyber and are new legal frameworks required? What are the latest trends in internet governance, cybercrime and cyber norms?

title: Street health: Practitioner service provision for Māori homeless people in Auckland

authors: Nikora, Linda Waimarie

abstract: Homelessness is more than a transient crisis. While access to housing might solve the needs of some, research has shown that the needs of homeless people are much more complex and more a symptom of systematic structural inequalities than an unanticipated emergency (Hopper, 1998). As in other countries, the homeless population in New Zealand is made up of a diverse population of men, women and intersex groups of various ages, sexualities and ethnic backgrounds. Māori are over-represented among this population due to ongoing processes of colonisation and socioeconomic exclusion (Groot et al., 2011). When compared with domiciled citizens, homeless people are more likely to experience a raft of illnesses and unmet health needs, violence, a sense of insecurity, exclusion and fear, and are more likely to commit sui- cide (Hodgetts et al., 2007). Homeless people often experience diverse ill- nesses including asthma, heart disease, diabetes, hepatitis, renal disease, dermatological conditions, malnutrition, oral disease, depression, schizo- phrenia, substance misuse and broken bones (Ellison-Loschmann & Pearce, 2006; Joly et al., 2011; Moore et al., 2007).
