A window for a purpose: developing a framework for describing effective science teaching and learning

This paper describes the development of a framework – the SIS Components – for describing effective teaching and learning in science, to support a system wide change initiative. The methodology used and the analysis that led to their refinement, is traced to expose the different issues involved in constructing the notion of lsquoeffective practice.rsquo These issues have to do with purpose, politics and audience. They determine features of the framework such as specificity, elements focused on, and the support structures that are put in place to establish the particular discourse being promoted. The paper describes the different research methods used to establish, to promote and to validate the components, and outlines the different senses in which this and any framework can be seen as contingent on the setting for which it is intended.

Personality and responses to appetitive and aversive stimuli: the joint influence of behavioural approach and behavioural inhibition systems

Gray’s reinforcement sensitivity theory (RST) posits two separable neurological systems involved in the regulation of personality and behaviour. The behavioural approach and inhibition systems facilitate the expression of appetitive (impulsive-sensation seeking traits) and aversive motivation (anxiety traits), respectively. Inconsistent findings regarding associations between measures of personality and behavioural responses to appetitive and aversive stimuli has led to a modification of RST including the notion that, rather than separable as first hypothesised, the two systems jointly influence behaviour. The current study was designed to investigate this proposal with an additional focus on the role of reinforcement expectancies. Seventy-eight participants completed two questionnaire measures of BIS/BAS activity (EPQ-R, SPSRQ) and two behavioural measures (Q-TASK, Card Arranging Reward Responsivity Objective Task). Findings were in general consistent with the original separable systems approach, however they also showed that aversive responses were highest in high BAS/high BIS individuals, thus suggesting an interactive account of BIS/BAS processes. Further, stronger positive correlations between self-report BAS traits and behavioural reward responsiveness were found for participants who perceived the task as more rewarding than initially expected. Discussion focuses on the role of reward expectancies and on the issue regarding separable vs. joint BIS/BAS systems.

Reactivity to alcohol-related cues: relationship among cue type, motivational processes, and personality

This study examined the relationship between personality traits implicated in the drinking literature (i.e., sensation seeking and anxiety) and reactivity to 2 different alcohol cues. The opportunity to consume alcohol was manipulated, and differences in urge and affective reactivity were assessed. Gray’s (1987) model of impulsive sensation seeking and anxiety was adopted to investigate relationships between personality and responses to the appetitive (consumption) and aversive (no consumption, nonrewarding) alcohol cues in 40 regular social drinkers. The consumption cue produced increases in appetitive motivation and positive correlations with sensation-seeking traits. The no-consumption cue produced increases in aversive motivation and positive correlations with anxiety-related traits. It was concluded that Gray’s model of impulsive sensation seeking and anxiety may provide a useful framework for examining the personality correlates of cue reactivity to different cues.

Bitterness suppression with zinc sulfate and na-cyclamate: a model of combined peripheral and central neural approaches to flavor modification

Purpose Zinc sulfate is known to inhibit the bitterness of the antimalarial agent quinine [R. S. J. Keast. The effect of zinc on human taste perception. J. Food Sci. 68:1871–1877 (2003)]. In the present work, we investigated whether zinc sulfate would inhibit other bitter-tasting compounds and pharmaceuticals. The utility of zinc as a general bitterness inhibitor is compromised, however, by the fact that it is also a good sweetness inhibitor [R. S. J. Keast, T. Canty, and P. A. S. Breslin. Oral zinc sulfate solutions inhibit sweet taste perception. Chem. Senses 29:513–521 (2004)] and would interfere with the taste of complex formulations. Yet, zinc sulfate does not inhibit the sweetener Na-cyclamate. Thus, we determined whether a mixture of zinc sulfate and Na-cyclamate would be a particularly effective combination for bitterness inhibition (Zn) and masking (cyclamate).

Method We used human taste psychophysical procedures with chemical solutions to assess bitterness blocking.

Results Zinc sulfate significantly inhibited the bitterness of quinine–HCl, Tetralone, and denatonium benzoate (DB) (p < 0.05), but had no significant effect on the bitterness of sucrose octa-acetate, pseudoephedrine (PSE), and dextromethorphan. A second experiment examined the influence of zinc sulfate on bittersweet mixtures. The bitter compounds were DB and PSE, and the sweeteners were sucrose (inhibited by 25 mM zinc sulfate) and Na-cyclamate (not inhibited by zinc sulfate). The combination of zinc sulfate and Na-cyclamate most effectively inhibited DB bitterness (86%) (p < 0.0016), whereas the mixture's inhibition of PSE bitterness was not different from that of Na-cyclamate alone.

Conclusion A combination of Na-cyclamate and zinc sulfate was most effective at inhibiting bitterness. Thus, the combined use of peripheral oral and central cognitive bitterness reduction strategies should be particularly effective for improving the flavor profile of bitter-tasting foods and pharmaceutical formulations.

The several social constructions of James, Jenks, and Prout: A contribution to the sociological theorization of childhood

The article is intended to contribute to the ongoing debate over theorizations of childhood, especially in the terms articulated by Allison James, Chris Jenkins and Alan Prout. The article focuses on the notion of social construction as a theory of childhood. There are four valid approaches to theorizing childhood. The tribal approach treats childhood as a kind of exotic tribe with its own beliefs, practices and institutions. The social structural approach treats childhood as a structurally necessary stratum in any society. The minority group approach treats childhood as an oppressed minority group, able to some extent to represent themselves and exert quasi-political action. The socially constructed approach constitutes the sociological view of childhood. The key role played by the idea of social construction is made extremely clear in the earlier work, Constructing and Reconstructing Childhood by James and Prout. Social constructionism is said to be an interpretive approach, related historically to research on children's understanding of adult experimenters' intentions. The senses of social construction that emerge from critical psychology overlap a great deal with those articulated in the new sociology of childhood.

A cross-national comparison of risk and protective factors for adolescent substance use : the United States and Australia

Purpose
To compare risk and protective factors that influence youth substance use in Australia and the United States. The two countries have different policy orientations toward substance use: Australia has adopted harm-reduction policies, and the United States has adopted abstinence-focused polices.

Methods
Cross-sectional survey data were collected from independent samples of adolescents in the states of Maine (N = 16,861; 53% female, 7% Non-white) and Oregon (N = 15,542; 51% female, 24% Non-white) in the United States and Victoria in Australia (N = 8442; 54% Female, 11% Non-white) in 1998 (Maine and Oregon) and 1999 (Victoria). Chi-square tests, t-tests, effect size comparisons, and logistic regression analyses that accounted for age and gender were used to investigate cross-national similarities and differences in: (a) rates of cigarette, alcohol, and marijuana use; (b) levels of risk and protective factors; and (c) magnitudes of associations between risk and protective factors and substance use.

Results
More adolescents in Victoria reported using cigarettes and alcohol, whereas more of the U.S. adolescents reported using marijuana. Exposure to risk and protective factors was generally similar in the cross-national samples. However, adolescents in Maine and Oregon perceived handguns to be more readily available, reported more participation in religious activities, and were higher in sensation-seeking and social skills; and adolescents in Victoria had more favorable attitudes toward drug use and reported community norms and parental attitudes more favorable to drug use. Most of the risk and protective factors were strongly associated with substance use to a similar degree in Victoria, Maine, and Oregon. However, among adolescents in Maine and Oregon peer/individual risk and protective factors associated with social detachment were more strongly related to substance use, and among adolescents in Victoria, family protective factors were less strongly related to alcohol use.

Conclusions
Inter-country influences on youth substance use are generally similar despite different policy directions. Existing differences suggest that the abstinence policy context is associated with higher levels of illicit drug use and stronger relations between individual indicators of social detachment and substance use, whereas the harm reduction policy context is related to more cigarette and alcohol use, possibly from exposure to normative influences that are more tolerant of youth drug use.

'Cum together' : spectatorship, presence and La Fura Baus' XXX

Based on the Marquis De Sade's novel, Philosophy in the Bedroom, XXX, a controversial work by the Spanish Performance group La Fura Dels, has divided critics and audiences in Europe and Australia. On the one hand, the performance has been chastised for its lack of intellectual coherence and tedium. On the other hand, it has been lauded as a piece of innovative theatre that addresses the audience's senses through a variety of theatrical and multi-media devices in order to challenge their preconceptions about the connections between sex and politics in contemporary culture. Writing in the Sydney Morning Herald, Stephen Dunne asks "Why is this so desperately-naughty show so dull to watch?"

This paper challenges Dunne's assessment of the performance by examining the relationship between the performers and spectators in terms of what Susan Melrose calls theatre's specular and somatic economies in order to analyse the specific ways in which XXX simultaneously challenges and confounds traditional notions of theatrical spectatorship.

From city symphony to global city film : documentary display and the corporeal

In the introduction to his history of the relationship between the body and the city in Western civilisation, Richard Sennett includes an anecdote about attending a cinema in New York. Sennett uses the story of watching film as a way of commenting on the place of the body and senses within urban settings and is concerned to document 'physical sensations in urban space' as a way of addressing what he sees as the 'tactile sterility which afflicts the urban environment.'[1] While Sennett's work performs an important task by drawing attention to various historical conditions implicated in urban and metropolitan experience, it is possible to rework the categories he deploys - bodies, the city, and film - into a very different argument concerning representations of the city. Indeed the three categories coalesce in the so-called city film - works which include the 'city symphony' of the 1920s and subsequent documentary representations of urban spaces, among them the New York City films of the 1940s and 1950s, and films of non-Western cities produced in the decades from the 1960s to the present - within which the city is realised through a focus on people.

Documentary display : re-viewing nonfiction film and video

Not all documentary films and videos are sober depictions of the real world. Documentary representations can present expressive, entertaining and spectacular images. This book examines such innovative approaches as they occur within the process of 'documentary display' - a practice which emphasises the visual attractions of documentary representation. Works of documentary display explore modes of exhibitionistic 'showing' in which sensation is frequently the vehicle of cognition and knowledge. Such a display is analysed within the popular and prominent forms of found-footage film, 'rockumentary', the city film, nonfiction surf film and video, and certain views of natural science topics. This accessible and informed study - with its focus on entertaining, popular, spectacular and sensational froms of nonfiction representation - makes an important contribution to theoretical analyses of documentary film and video

Partnerships and place : mobilising resources from outside

Partnerships facilitate sharing of resources and can create outcomes that are more than the sum of partners’ contributions. The concept of partnership has entered policy rhetoric and is urged as good practice, sometimes along with consideration of place. For example, Mears et al’s recent academic critique of health policy holds that modern health systems should have a sense of place and be partnership orientated, as well as being primary care based and pragmatic in adopting effective practice. It is easy to regard partnership as unequivocally a good thing, however this is a simplistic view that ignores issues such as power imbalances, self-seeking behaviour of partners and the often complex, resource intensive and sensitive process required to establish and sustain partnerships. Rural communities tend to have fewer resources available for the provision of services such as health and education than their metropolitan counterparts, and so could be expected to benefit from partnerships with outside services and resource providers. Factors such as distance and lack of power in many professional and political domains imply that rural communities are also more likely to encounter barriers in establishing and maintaining partnerships with metropolitan based partners.

There is a growing literature on the composition and outcomes of partnerships in a variety of contexts and settings, including rural place-based communities, but relatively little about the partnership process. Understanding this process is a key step in designing policy at the system level and in developing and maintaining partnerships at the grass roots level. This paper makes a contribution to this gap by presenting lessons from the analysis of rural-urban partnerships around health services for two rural Tasmanian communities.

Improving the uptake of pulmonary rehabilitation in patients with COPD : qualitative study of experiences and attitudes

Background
Pulmonary rehabilitation can improve the quality of life and ability to function of patients with chronic obstructive pulmonary disease (COPD). It may also reduce hospital admission and inpatient stay with exacerbations of COPD. Some patients who are eligible for pulmonary rehabilitation may not accept an offer of it, thereby missing an opportunity to improve their health status.

Aim
To identify a strategy for improving the uptake of pulmonary rehabilitation.

Design of study
Qualitative interviews with patients.

Setting
Patients with COPD were recruited from a suburban general practice in north-east Derbyshire, UK.

Method
In-depth interviews were conducted on a purposive sample of 16 patients with COPD to assess their concerns about accepting an offer of pulmonary rehabilitation. Interviews were analysed using grounded theory.

Results
Fear of breathlessness and exercise, and the effect of pulmonary rehabilitation on coexisting medical problems were the most common concerns patients had about taking part in the rehabilitation. The possibility of reducing the sensation of breathlessness and regaining the ability to do things, such as play with their grandchildren, were motivators to participating.

Conclusion
A model is proposed where patients who feel a loss of control as their disease advances may find that pulmonary rehabilitation offers them the opportunity to regain control. Acknowledging patients' fears and framing pulmonary rehabilitation as a way of ‘regaining control’ may improve patient uptake.

Feminist poetics : symbolism in an emblematic journey reflecting self and vision

My thesis tilled Feminist Poetics: Symbolism in an Emblematic Journey Reflecting Self and Vision, consists of thirty oil paintings on canvas, several preparatory sketches and drawings in different media on paper, and is supported and elucidated by an exegesis. The paintings on unframed canvases reveal mise en scčnes and emblems that present to the viewer a drama about links between identities, differences, relationships and vision. Images of my daughter, friends and myself fill single canvases, suites of paintings, diptyches and triptychs. The impetus behind my research derives from my recognition of the cultural means by which women's experience is excluded from a representational norm or ideal. I use time-honoured devices, such as, illusionist imagery, aspects of portraiture, complex fractured atmospheric space, paintings and drawings within paintings, mirrors and reflective surfaces, shadows and architectural devices. They structure my compositions in a way that envelops the viewer in my internal world of ideas. Some of these features function symbolically, as emblems. A small part of the imagery relies on verisimilitude, such as my hands and their shadow and my single observing eye enclosed by my glasses. What remains is a fantasy world, ‘seen’ by the image of my other eye, or ‘faction’, based on memories and texts explaining the significance of ancient Minoan symbols. In my paintings, I base the subjects of this fantasy on my memories of the Knossos Labyrinth and matristic symbols, such as the pillar, snake, blood, eye and horn. They suggest the presence of a ritual where initiates descended into the adyton (holy of holies) or sunken areas in the labyrinth. The paintings attempt a ‘rewriting’ of sacrality and gender by adopting the symbolism of death, transformation and resurrection in the adyton. The significance of my emblematic imagery is that it constructs a foundation narrative about vision and insight. I sought symbolic attributes shared by European oil painting and Minoan antiquity. Both traditions share symbolic attributes with male dying gods in Greek myths and Medusa plays a central part in this linkage. I argue that her attributes seem identical to both those of the dying gods and Minoan goddesses. In the Minoan context these symbols suggest metaphors for the female body and the mother and daughter blood line. When the symbols align with the beheaded Medusa in a patriarchal context, both her image and her attributes represent cautionary tales about female sexuality that have repercussions for aspects of vision. In Renaissance and Baroque oil painting Medusa's image served as a vehicle for an allegory that personified the triumph of reason over the senses. In the twentieth century, the vagina dentata suggests her image, a personified image of irrational emotion that some male Surrealists celebrated as a muse. She is implicated in the male gaze as a site of castration and her representation suggests a symbolic form pertaining to perspective. Medusa's image, its negative sexual and violent connotations, seemed like a keystone linking iconographic codes in European oil painting to Minoan antiquity. I fused aspects of matristic Minoan antiquity with elements of European oil paintings in the form of disguised attribute gestures, objects and architectural environments. I selected three paintings, Dürer's Setf-Portrait, 1500, Gentileschi's Self-Portrait as the Allegory of Painting, 1630 and Velazquez's Las Meniruis, 1656 as models because 1 detected echoes of Minoan symbolism in the attributes of their subjects and backgrounds. My revision of Medusa's image by connecting it to Minoan antiquity established a feminist means of representation in the largely male-dominated tradition of oil painting. These paintings also suggested painting techniques that were useful to me. Through my representations of my emblematic journey I questioned the narrow focus placed on phallic symbols when I explored how their meanings may have been formed within a matricentric culture. I retained the key symbols of the patriarchal foundation narratives about vision but removed images of violence and their link to desire and replaced it with a ritual form of symbolic death. I challenged the binary oppositional defined Self as opposed to Other by constructing a complex, fluid Self that interacts with others. A multi-directional gaze between subjects, viewers and artist replaces the male gaze. Different qualities of paint, coagulation and random flow form a blood symbolism. Many layers of paint retaining some aspects of the Gaze and Glance, fuse and separate intermittently to construct and define form. The sense of motion and fluidity constructs a form of multi-faceted selves. The supporting document, the exegesis is in two parts. In the first part, I discuss the Minoan sources of my iconography and the symbolic gender specific meanings suggested by particular symbols and their changed meanings in European oil painting, I explain how I integrate Minoan symbols into European oil paintings as a form of disguised symbolism. In the second part I explain how my alternative use of symbolism and paint alludes to a feminist poetic.
