title: Modelling single cell electroporation with bipolar pulse parameters and dynamic pore radii

authors: Talele, Sadhana

subjects: electroporation

abstract: We develop a model of single spherical cell electroporation and simulate spatial and temporal aspects of the transmembrane potential and pore radii as an effect of any form of applied electric field. The extent of electroporation in response to sinusoidal electric pulses of two different frequencies in a range of extracellular conductivity for two different cell radii are compared. Results show that pore radii tend to be more normalized for AC fields. The relative difference in fractional pore area is reduced by the use of a 1 MHz sinusoidal applied electric field over a 100 kHz field.

title: Teaching & learning guide for: Social psychology and media: Critical Consideration

authors: Hodgetts, Darrin

subjects: psychology

abstract: We wrote this paper because we felt there was a need for a more critical examination of the ways that media were considered within social psychology. The article was written to provide an overview of social psychological research on media and to propose new lines of enquiry, particularly into the social practices within which media technologies are embedded. In particular our arguments focus on the ways in which media permeate social life and relationships, and why we should give more attention to the study of media within the practices of everyday living. Media are pervasive in society today. Media are foundational to the symbolic landscape within which people make sense of the world and their place in it. Media also comprise material objects, such as televisions and computers that dominate many domestic realms, as well as more portable devices, such as mobile phones and MP3 players that people take with them when moving through everyday life. Human relations with and through media are complex and evolving, and provide a core focus for social psychology. In the living room of any modern home there are likely to be comfortable chairs, family memorabilia and a range of media technologies ranging from telephones, radios, books and magazines to a television, a DVD player, a digital recorder, iPod, and perhaps a networked computer. These devices are often mobile, and can be moved or relocated around the house, shifting from communal to more personal devices as family members seek privacy to consume their media products or react to different tastes in movie, musical or gaming content. Such practices open up a range of social psychological issues regarding human relations, identity, time and space. The presence of media devices in daily life has invoked concerns about the possible negative effects of exposure to media violence and broader issues around reduced civic participation, as well as more positively focused issues such as the use of media to build and maintain social ties.

title: Eke Panuku, Eke Tangaroa: He Taonga Tuku Iho

authors: Apanui, Ngahiwi

subjects: Panuku

abstract: He aha te Māori? He aha i kīia ai tētahi āhuatanga, tētahi mahi, tētahi tangata, tētahi whakahaere rānei he Māori? Ko te whāinga o te rangahau nei he rapa huarahi e āhei ai te whakautu i ēnei pātai. Me te huhua hoki o te whakaaro mō ēnei pātai, i huri ahau ki ngā mātanga, ngā pūkenga hoki o te ao mātauranga Māori hei taunaki i te whakautu ki te pātai. 
Ka tūhura te rangahau nei i te rētōtanga o te ao Māori, ka titiro hoki ki te āhua i Māori ai ētahi āhuatanga me te whakautu, he ahurea Māori i Māori ai tētahi āhuatanga, tētahi mahi, tētahi tangata, tētahi whakahaere rānei – ko te pū ahurea Māori tēnei. Ka titiro anō hoki te rangahau nei ki te whakaaro Māori hei tūāpapa mō te pū ahurea Māori, te wāhanga ki ngā kaupapa tuku iho me te whakaatu a te tikanga i te kaupapa. 
Ko te hua o te rangahau nei, he tuku i te rauemi e taea ai te tangata te tautuhi me te ine i te pū ahurea Māori hei ārahi i te aromātaitanga o ngā mahi Māori.
