title: Social media adoption by microbusinesses

authors: Mandal, Debashish

subjects: Social media

abstract: The social media implementation process (initiation, adoption, adaptation, acceptance, use and incorporation) is examined in correlation with the five factors (individual, organisational, technological, environmental and performance). Numerous existing theories from the innovation, technology adoption and performance measurement literature are used to derive probable relation between the implementation process and the five factors. Such expansive scope and comprehensive theory development has been articulated but never attempted. To manage the large scope, microbusinesses are selected purposefully due to their limited business processes. The research design reflects the need for relevance by using Lewin’s action research (traditional social change model) as the primary method augmented by participant observation (physical and online). Data collection uses a mix of unstructured, semi-structured and structured interviews assisted by structured observation. Data analysis uses a set of routines, such as tabulation, categorisation, abstraction and verification, involving prediction and testing.
The research finds that a collaborative process to address concerns, along with quick start and self-training, helped to adopt social media. Participants needed to focus on concrete experience, work-place learning and personal knowledge for learning to use social media. Usefulness arising from improved communication, fitness and medium richness was the dominant indicator for acceptance and use. Continued use relied on satisfaction and habit of the user. Individual characteristics and personality factors both seemed to be a poor indicator of adoption with weak links towards extroversion. Microbusinesses suffered primarily from context and mental mode related challenges for social media use. Type of business, such as service shops, had a greater probability of success. Social media positively affected relationship marketing in terms of service quality. Business activity associated with specialisation seemed to perform poorly with social media. Finally, performance measurement techniques included finding the capability of social media to meet survival objectives, improve capacity utilisation and business resale value.

title: 1,2-Bis{(pentafluorophenyl)phenylphosphino}ethane:  A Probe for Configurational Stability in Three-Legged Piano Stool Complexes

authors: Nieuwenhuyzen, Mark

subjects: chemistry

abstract: The pentafluorophenyl-substituted diphosphine (C₆F₅)PhPCH₂CH₂PPh(C₆F₅) has been prepared, as a 1:1.7 mixture of rac (1a) and meso (1b) isomers, in four steps from dppe. The reaction between [Cp*RhCl(μ-Cl)]2 and 1 in the presence of tetrafluoroborate yielded a mixture of racemic diastereoisomers of [Cp*RhCl(κP,κP-1a)][BF₄] (4a•BF₄) and trans and cis isomers of [Cp*RhCl(κP,κP-1b)][BF₄] (4b•BF₄ and 4c•BF₄, respectively). On addition of Proton Sponge, 4a and 4c, in which at least one pentafluorophenyl group is close to the pentamethylcyclopentadienyl ligand, underwent rapid dehydrofluorinative carbon−carbon coupling giving trans- and cis-[{η⁵,κP,κP-C₅Me₄CH₂C₆F₄-2-PPhCH₂CH₂PPh(C₆F₅)}RhCl]⁺ (5 and 6), respectively. The latter underwent further dehydrofluorinative carbon−carbon coupling to give two isomers of [{η⁵,κP,κP-C₅Me₃[CH₂C₆F₄-2-PPhCH₂]₂}RhCl]+ (7). Isomerization of 4b to 4c was observed in chloroform and dimethlysulfoxide. Neither isomerization of 4a to 4b or 4c nor isomerization of 5 to 6 was observed at ambient or elevated temperature in dimethyl sulfoxide. The results provide the first evidence that complexes of η⁵,κP,κL-cyclopentadienyl-phosphine-donor ligands are configurationally stable at high temperature.

title: An evaluation of the Raukawa Health Services Kaumatua Mirimiri Programme

authors: Gregg, Lisa

subjects: Maori

abstract: The Kaumatua Mirimiri Programme was funded as a Service to Improve Access project under a contract which ran from 1st September 2004 to 30th June 2005. Its aim was to provide a “culturally based treatment and recovery programme to restore the health and independence” of people aged 40 years and over (Pinnacle Group Ltd, 2004a, p.1). However, as the service specification in the contract made clear, the programme was not designed be exclusive: it has attracted younger as well as older people, non-Māori as well as Māori, and people seeking help for a wide range of ailments and pain.
