title: Blurring the lines: the vague boundary between mainstream and deviant internet pornography tags for at-risk viewers

authors: Gane, G

abstract: Illegal material is increasingly appearing on popular mainstream websites. Many commentators worry about the impact of such material on adolescents' psycho-sexual development and the potential for some legal pornography to act as a gateway to child sexual exploitation material for users of any age. In this study, we collected publicly available data from a popular legal pornography website to assess the risk of adolescent exposure to content that may hinder healthy psycho-sexual development. We analysed over 27 million customer searches involving 149 video tags from this site. Five international experts on the effects of pornography rated the tags, categorising them into five overlapping genres: mainstream, incestuous, underage, aggressive and non-consensual. They also assessed the potential risk each genre posed. Our analysis found a significant positive correlation between the harm ratings and the frequency of tags used as search terms. Additionally, eleven of the twelve tags with the highest mean risk scores involved potential underage and/or incestuous content. This study highlights a concerning relationship between the harm ratings of various pornographic genres and their popularity as search terms. While exploratory, these results emphasise the need for regulatory measures to address the presence of harmful material on mainstream websites. PRACTICE IMPACT STATEMENT: The study has practical implications for the regulation of potentially harmful pornography by legal pornography sites. The sites should (a) control the use of tags and how new tags are developed in order to prevent content creators from advertising potentially illegal material, (b) vet all content before it is uploaded for public consumption, and (c) implement screening systems to retrospectively find and eradicate all illegal or harmful content already in their collection.

title: Instabilities of the cortex during natural sleep

authors: Wilson, Marcus T.

subjects: cortex

abstract: The electrical signals generated by the human cortex during sleep have been widely studied over the last 50 years. The electroencephalogram (EEG) observed during natural sleep exhibits structures with frequencies from 0.5 Hz to over 50 Hz and complicated waveforms such as spindles and K-complexes. Understanding has been enhanced by comprehensive intra-cellular measurements from the cortex and thalamus such as those performed by Steriade et al [1] and Sanchez-Vives and McCormick [2]. Models of the cerebal cortex have been developed in order to explain many of the features observed. These can be classified in terms of individual neuron models or collective models. Since we wish to compare predictions with gross features of the human EEG, we choose a collective model, where we average over a population of neurons in macrocolumns. A number of models of this form have been developed recently; that developed at Waikato draws from a number of different sources to describe the temporal and spatial dynamics of the system.

title: The challenges of culture to psychology and post-modern thinking

authors: Waldegrave, Charles

subjects: Maori

abstract: Someone at a workshop in the Waikato once said to us, “You know a Maori, if they want to, can always learn to be a psychologist, but a psychologist can’t learn to be a Maori”. Cultural knowledge may or may not be accompanied by social science knowledge. Cultural knowledge can stand on its own. Those who possess it, and choose to work in the institutions we are associated with, have gifts this country desperately needs. All our organisations require such people, and they need to be properly resourced, have employment security and control over their work. Their own work away from our organisations also requires adequate resourcing. They can heal their own in ways that we will never be able to. They will almost certainly offer the field rich alternative metaphors and meanings that can free us from the tired old medical, biological and social science ones. This also has implications for those in other branches of psychology, including research, experimental and industrial psychology. There is perhaps a unique opportunity for psychologists in this country of Aotearoa/New Zealand to recognise other ways of describing events, which will lead to creative practices and enable the health and welfare resources to get to those who most need them, on their own terms. It would also enable other people, other workers from other cultures to develop new paradigms, and new shifts in our field. This will not lead to the abandonment of social science, but it will enable that body of knowledge, to sit appropriately along side other realms of knowledge such as gender knowledge, and cultural knowledge, without dominating. A new experience for the social scientists, but I suspect a liberating one!
