Crossing cultural boundaries, flexible approaches and nurse education : a case study

Computer-mediated conferencing commonly is used to promote collaborative learning, including student learning across distance. This article presents the outcomes and experiences of Master of Nursing students in three countries using flexible learning approaches facilitated by the use of computer-mediated conferencing. It examines issues relating to support for global nursing education, presents an evaluation of one particular unit, and presents themes in the feedback from students about their experience. The authors report the findings in three categories: broadened perspectives, tackling the technology, and adaptive learning. Furthermore, the article offers suggestions for enhancing student-learning experiences when computer-mediated conferencing facilities are used.

Ego boundaries, shamanic-like techniques, and subjective experience : an experimental study

The subjective effects and therapeutic potential of the shamanic practice of journeying is well known. However, previous research has neglected to provide a comprehensive assessment of the subjective effects of shamanic-like journeying techniques on non-shamans. Shamanic-like techniques are those that demonstrate some similarity to shamanic practices and yet deviate from what may genuinely be considered shamanism. Furthermore, the personality traits that influence individual susceptibility to shamanic-like techniques are unclear. The aim of the present study was, thus, to investigate experimentally the effect of shamanic-like techniques and a personality trait referred to as "ego boundaries" on subjective experience including mood disturbance. Forty-three non-shamans were administered a composite questionnaire consisting of demographic items and a measure of ego boundaries (i.e., the Short Boundary Questionnaire; BQ-Sh). Participants were randomly assigned to one of three conditions: listening to monotonous drumming for 15 minutes coupled with one of two sets of journeying instructions; or sitting quietly with eyes closed for 15 minutes. Participants' subjective experience and mood disturbance were retrospectively assessed using the Phenomenology of Consciousness Inventory (PCI) and the Profile of Mood States-Short Form, respectively. The results indicated that there was a statistically significant difference between conditions with regard to the PCI major dimensions of visual imagery, attention and rationality, and minor dimensions of imagery amount and absorption. However, the shamanic-like conditions were not associated with a major reorganization of the pattern of subjective experience compared to the sitting quietly condition, suggesting that what is typically referred to as an altered state of consciousness effect was not evident. One shamanic-like condition and the BQ-Sh subscales need for order, childlikeness, and sensitivity were statistically significant predictors of total mood disturbance. Implications of the findings for the anthropology of consciousness are also considered.

Regional-scale models for relating land cover to basin surface-water quality using remotely sensed data in a GIS

Plant-based management systems implementing deep-rooted, perennial vegetation have been identified as important in mitigating the spread of secondary dryland salinity due to its capacity to influence water table depth. The Glenelg Hopkins catchment is a highly modified watershed in the southwest region of Victoria, where dryland salinity management has been identified as a priority. Empirical relationships between the proportion of native vegetation and in-stream salinity were examined in the Glenelg Hopkins catchment using a linear regression approach. Whilst investigations of these relationships are not unique, this is the first comprehensive attempt to establish a link between land use and in-stream salinity in the study area. The results indicate that higher percentage land cover with native vegetation was negatively correlated with elevated in-stream salinity. This inverse correlation was consistent across the 3 years examined (1980, 1995, and 2002). Recognising the potential for erroneously inferring causal relationships, the methodology outlined here was both a time and cost-effective tool to inform management strategies at a regional scale, particularly in areas where processes may be operating at scales not easily addressed with on-site studies.

The hybrid self and the ambivalence of boundaries

The paper outlines the main features of the contemporary discourse on hybrid subjectivity, a discourse which is internally differentiated along 'organic', 'intentional', and critical social theory lines. It then examines how these discourses can be applied to our understanding of hybrid cultures and identities. The article focuses on two central claims underlying the intentional approach: one, that cultural boundaries are theoretically and empirically problematic; and secondly, that a hybrid position provides the potential for an enlightened and critical world-view. In response, two contentions are articulated that will provide a more nuanced understanding of the hybrid self. Drawing on the work of Simmel and Park, the paper, in contrast to the intentional account, highlights the ambivalence of boundaries; secondly, a critical investigation of the enlightened hybrid consciousness is offered which suggests that this new form of consciousness underplays the role of prejudice and ambivalence. As a result of these discussions, the article demonstrates that the discourse on hybrid identity raises key theoretical issues either ignored or insufficiently addressed by existing scholarship.

Quantum bioenergetics, mental boundaries and affective response : a randomized placebo-controlled pilot study

Previous research has demonstrated the effects of ostensible subtle energy on physical systems and subjective experience. However, one subtle energy technique that has been neglected by previous studies, despite anecdotal support for its efficacy, is Quantum BioEnergetics (QBE). Furthermore, personality traits that influence subtle energy effects remain unclear, and previous experimental studies have not investigated the constructs of Love and Joy, despite qualitative and anecdotal reports indicating that these variants of positive affect are essential elements of the subtle energy experience. The aim of the present study was to investigate experimentally the effects of QBE, and the personality trait Mental Boundaries, on positive and negative affect. Participants (N = 69) were administered the Boundary Questionnaire Short Form to quantify Boundaries, and then randomly assigned to one of three conditions: QBE, Placebo ("sham"), or Control. Affect was retrospectively assessed using the Positive and Negative Affect subdimensions of the Phenomenology of Consciousness Inventory (PCI). As predicted, a significant multivariate effect for condition was found with regards to the PCI subdimensions: Joy, Sexual Excitement, Love, Anger, Sadness, and Fear. In contrast to our expectations, a significant multivariate effect was not found for Boundaries with regards to the combined PCI-Affect variables. As hypothesized, significant interactions were found between condition and Boundaries with regards to Positive Affect, Love and Joy, with the QBE/Thin Boundaries factorial combination associated with the highest mean scores for these dependent variables. It will be prudent to ascertain whether these results are replicated in a larger sample and a placebo condition that improves on the standard randomized placebocontrolled protocols of previous subtle energy research.

Hair braiding : working the boundaries of methodology in globalisation research

This paper engages the constitutive as well as the representative role of metaphor in research. Metaphors are understood to provide possibilities for representations and conceptualisations. The use of metaphorical redescription permits us to 'use familiar words in unfamiliar ways' (Rorty, 1989, p. 18) and provides new language that deters the use of repeated ways of knowing. It invites us to see things differently and to act differently. Lakoff and Johnson (1980) argue that metaphor does more than represent: 'New metaphors have the power to construct a new reality' (p. 145). I have drawn on both these understandings of metaphor. In qualitative research, metaphorical analysis has a well-established history. Researchers analyse metaphors used by research participants and apply metaphors to participant actions and understandings (Koro-Ljungberg, 2001; Gregory & Noblit, 1998). Researchers also use metaphors to reflect or represent their methodological decision-making (Richardson, 2003; Gadamer, 1989). In this article, I have nudged the conceptual boundaries of methodology. I have argued the constructive nature of metaphor in methodological positioning and decision making. I use the writing of a doctoral thesis to argue this role of metaphor. There, the metaphor of hair braiding constructed and communicated my methodological decision-making and my researcher stance as a braider.

Revised stratigraphy of the Blanchetown Clay, Murray Basin: age constraints on the evolution of paleo Lake Bungunnia

Paleo Lake Bungunnia covered more than 40 000 km2 of southern Australia during the Plio-Pleistocene, although the age and origin of the lake remain controversial. The Blanchetown Clay is the main depositional unit and outcrop at Nampoo Station in far-western New South Wales provides the most continuous lacustrine section preserved in the basin. Here the Blanchetown Clay represents the maximum lake fill and comprises: (i) a basal well-sorted sand with interbedded clay (Chowilla Sand), representing initial flooding at the time of lake formation; (ii) a thick sequence of green-grey clay comprised dominantly of kaolinite and illite, with the apparently cyclic occurrence of illite interpreted to represent cool and dry glacial climatic intervals; and (iii) a 2.6 m-thick sequence of finely laminated silt and silty clay, here defined as the Nampoo Member of the Blanchetown Clay. New magnetostratigraphic data constrain the age of the oldest lake sediments to be younger than 2.581 Ma (Matuyama-Gauss boundary) and probably as young as 2.4 Ma. This age is significantly younger than the age of 3.2 Ma previously suggested for lake formation. The youngest Blanchetown Clay is older than 0.781 Ma (Brunhes-Matuyama boundary) and probably as old as 1.2 Ma. The Nampoo Station section provides a framework for the construction of a regional Plio-Pleistocene stratigraphy in the Murray Basin.
