title: Breaking the Intergenerational Cycle of Physical Punishment

authors: Sturkenboom, Gina Alicia

subjects: physical punishment

abstract: Fifteen women and five men participated in a study aimed at devising strategies to reduce the use of physical punishment in New Zealand. The potential problems with the use of physical punishment, the extent of its use in New Zealand, and the likelihood of intergenerational transmission are discussed to justify the aim of the study. 

The participants were all parents who had been smacked themselves, but who had decided not to smack their own children. Their ages ranged from 28 to 57, and only three had less than some tertiary education. They were from various ethnic backgrounds; fourteen had an occupation other than parenting, and nine were single parents.

The participants had broken the intergenerational cycle of physical punishment: they had been smacked themselves but did not smack their own children. All participated in an individual, semi-structured interview, in which their childhood physical punishment, their decision not to smack, the maintenance of that decision, and their use of alternative disciplinary techniques were discussed. Four participated in a focus group, in which the strategies suggested in the interviews were discussed and refined to produce a final list of recommendations.
  
The parents made a conscious decision against smacking, which involved a particular experience that prompted them to consider their disciplinary practices. Negative views of smacking (ineffective, modelling violence, and potential to escalate) were also helpful in making the decision. 
 
While maintaining their decision was usually easy, alternative techniques were sometimes hard to use, though effective in the long term. Some had to deal with the effects of deviating from a childrearing norm, particularly in regard to other family members. While many were satisfied that their own children were free from physical punishment, some had actively tried to convince other parents not to use it as well. 
 
They recommended strategies aimed at achieving the goals of parent education, raising awareness, reducing strain, and increasing support for parents. They also suggested practical steps that individual parents who were interested in breaking the cycle of physical punishment could take. 

The limitations and strengths of the study are discussed, as well as the implications for further research. The study demonstrates that parenting without physical punishment is effective, desirable, and achievable, even by parents who were smacked themselves. It presents a number of possible strategies and intermediate goals, for interventions at a national, community, or individual level, which aim to reduce the use of physical punishment.

title: Measuring the electrical impedance of mouse brain tissue

authors: Wilson, Marcus T.

abstract: We report on an experimental method to measure conductivity of cortical tissue. We use a pair of 5mm diameter Ag/AgCl electrodes in a Perspex sandwich device that can be brought to a distance of 400 microns apart. The apparatus is brought to uniform temperature before use. Electrical impedance of a sample is measured across the frequency range 20 Hz-2.0 MHz with an Agilent 4980A four-point impedance monitor in a shielded room. The equipment has been used to measure the conductivity of mature mouse brain cortex in vitro. Slices 400 microns in thickness are prepared on a vibratome. Slices are bathed in artificial cerebrospinal fluid (ACSF) to keep them alive. Slices are removed from the ACSF and sections of cortical tissue approximately 2 mm times 2 mm are cut with a razor blade. The sections are photographed through a calibrated microscope to allow identification of their cross-sectional areas. Excess ACSF is removed from the sample and the sections places between the electrodes. The impedance is measured across the frequency range and electrical conductivity calculated. Results show two regions of dispersion. A low frequency region is evident below approximately 10 kHz, and a high frequency dispersion above this. Results at the higher frequencies show a good fit to the Cole-Cole model of impedance of biological tissue; this model consists of resistive and non-linear capacitive elements. Physically, these elements are likely to arise due to membrane polarization and migration of ions both intra- and extra-cellularly.

title: Māori and Pacific language data in linguistics classes

authors: Barbour, Julie Renee

abstract: Māori and Pacific language data rarely appears in introductory linguistic text books. In a discipline with a dearth of Māori and Pacific scholars, there is an opportunity to reflect on our teaching materials and consider ways in which we can make our classes more inclusive spaces. In this presentation, we share some of the materials and associated activities that we incorporate into undergraduate linguistics classes, in an effort to make our disciplinary content more attractive to students who join our classes with a variety of heritage languages.
