Defuturing an architecture of destruction: a reconciliation of Van Berkel and Bos to the new design philosophy of Tony Fry

For some time now Tony Fry has promoted the idea of 'The Sustainment', an idea that asserts a paradigm shift in attitudes to consumption. 'The Sustainment' recognises that increasingly human futures are products of self-determination and not chance. Fry’s hypothesis can be understood through his concept of Defuturing, a philosophy that questions the role of design and the responsibility of designers to facilitating the ability to sustain (Fry 1999).
Central to Fry’s philosophy is an awareness that it is in the best interests of designers and their clients, as inhabitants of cultures increasingly driven by technology, to be aware of the relationships between the products and theories of design and the processes and implications of technological change. This is an awareness that is central to the concepts, work, and methodologies of the ‘UN Studio’ of Van Berkel and Bos described and elaborated upon in Move – Imagination, Techniques, and Effects (Van Berkel & Bos 1999). Here, Ben Van Berkel defines the parameters and methodologies employed by UN Studio in an environment of technological and socio-economic change. The Dutch practice could be said to exemplify something of a zeitgeist in current architectural design that sees architects, as Van Berkel and Bos view them, as “fashion designers of the future, dressing events to come and holding up a mirror to the world (Van Berkel & Bos 1999, back cover).” It is a zeitgeist that Fry might see as aligned to the resilient hype of ‘new creativity’, ‘globalisation’ the ‘romance with technology’, and the vacuous-ness of the world of fashion. (Fry The Voice of Sustainment: on Design Intelligence 2005).
A source of breaking down such design propaganda is identified by Fry in the notion of ‘scenarios,’ which “provide a mechanism for politico-practice assemblage in which dialogues and narratives of change can be rehearsed in ways that enable participants to re-educate themselves via critical confrontations” (Fry The Voice of Sustainment: on Design Intelligence 2005). From such a perspective this paper aims to practically illustrate and ground the Defuturing of Fry by establishing a dialogue between his writings and the theories that have generated the architectural designs of Van Berkel and Bos and there UN Studio. This will be a ‘scenario’ that examines therefore an appropriation and transformation of the applied intellectual practice of Van Berkel and Bos. Through this confrontation we shall explore the question of why sustainability appears to be so low in the agenda of many pre-eminent contemporary architects, and how we might refocus therefore practice and theory on the ability to sustain.

Evidence-based mental health nursing in Australia: our history and our future

This paper will develop a discussion related to evidence-based knowledge for mental health nursing, arguing for a historical component to be included in the comprehensive degree programme that will offer significant insights into mental health nursing knowledge from historical information and constructing implications for contemporary practice. Our understanding of the present is clearer by this looking back and forth and by adding meaning (and what the meanings mean) to what historically preceded. It allows the history of psychiatry to be a much more productive, useful, and a continual source of wisdom for the here and now. This blending of past knowledge with contemporary inquiry can offer depth in mental health nursing practices by forming a context for practice for the beginning nurse practitioner.

Key stakeholders' expectations of educational outcomes from Australian critical care nursing courses: a Delphi study

Background
Educational preparation for critical care nursing in Australia varies considerably in terms of the level of qualification resulting in a lack of clarity for key stakeholders about student outcomes.

Objectives
The study aim was to identify and reach consensus regarding the desired learning outcomes from Australian post-registration critical care education programs as demonstrated through the graduate's knowledge, skills and attitudes.

Design
A Delphi technique was used to establish consensus between educators, managers, clinicians and students regarding learning outcomes expected of graduates with a Graduate Certificate, Graduate Diploma and Master level qualification in critical care nursing.

Participants
A total of 164 critical care nurses (66 clinicians, 48 educators, 32 managers and 18 students) participated and 99 questionnaires were returned in the first round (response rate 60%). Fifty-seven questionnaires were returned for Round 2 (response rate 58%).

Methods
Learning outcomes were obtained from the Australian College of Critical Care Nurses Competency Standards for Specialist Critical Care Nurses. Some statements included more than one characteristic, and these were split to create learning outcomes with one characteristic per item. A survey of Australian higher education providers of critical care education provided additional learning outcomes, for a total of 73 learning outcomes for the first Delphi round.

Results
Findings suggest that patient comfort, safety, professional responsibility and ethical conduct are deemed most important for all three levels of educational preparation. There was a lack of emphasis on clinical practice issues for all levels. Participants placed higher emphasis on learning outcomes related to complex decision-making, leadership, supervision, policy development and research for Graduate Diploma and Master level programs.

Conclusion
The findings have implications for curriculum development and the profession with regards to the level of educational preparation required of critical care nurses and suggest that further work is required before clear recommendations can be made for desired educational outcomes from critical care nursing programs in Australia.

How practice size impacts on the implementation and dissemination of post occupancy evaluation

There has been much research on the subject of environmentally sustainable design (ESD), with emerging techniques and technologies improving rapidly and informing sustainability higher education teaching to architects and prospective architects. By examining the success of sustainable designs using post occupancy evaluations, architectural practices might also increase their knowledge of sustainable building practice. Post occupancy evaluations could be useful for improving the designs of future buildings and the design processes that generated them. This paper aims to evaluate these claims by asking: "Do sustainable design practices use the feedback gained from post occupancy evaluations?," "How does the feedback refine the design process?," "How is the information gained in these evaluations absorbed within the firm's design practices?," and, "Does the size of a practice impact on its implementation and
dissemination of POE?" This paper investigates the questions posed above through the questioning of architectural practices that have gained a reputation for environmentally sustainable design by having a strong sustainable design philosophy and/or by being recognised for this by winning a sustainability design award. The interviewed practices will have provided some form of post occupancy evaluation as a service or employed them to add to their own knowledge.

Clinical education : a challenging component of undergraduate nursing education

Clinical education is an essential part of every undergraduate nursing curriculum. The main benefits are that it allows students to put theory into practice and experience the realities of the practice- based nursing profession. Limitations include the unstable nature of the clinical area as a learning environment and the challenges this produces with students' assessments. This article reviews the literature and concludes there is room for significant improvement in the area of clinical education and numerous strategies can be implemented to do so.

Nursing administration of medication via enteral tubes in adults : a systematic review

Background Enteral tubes are frequently inserted as part of medical treatment in a wide range of patient situations. Patients with an enteral tube are cared for by nurses in a variety of settings, including general and specialised acute care areas, aged care facilities and at home. Regardless of the setting, nurses have the primary responsibility for administering medication through enteral tubes. Medication administration via an enteral tube is a reasonably common nursing intervention that entails a number of skills, including preparing the medication, verifying the tube position, flushing the tube and assessing for potential complications. If medications are not given effectively through an enteral tube, harmful consequences may result leading to increased morbidity, for example, tube occlusion, diarrhoea and aspiration pneumonia. There are resultant costs for the health-care system related to possible increased length of stay and increased use of equipment. Presently what is considered to be best practice to give medications through enteral tubes is unknown.

Objectives The objective of this systematic review was to determine the best available evidence on which nursing interventions are effective in minimising the complications associated with the administration of medications via enteral tubes in adults. Nursing interventions and considerations related to medication administration included form of medication, verifying tube placement before administration, methods used to give medication, methods used to flush tubes, maintenance of tube patency and specific practices to prevent possible complications related to the administration of enteral medications.

Search strategy The following databases were searched for literature reported in English only: CINAHL, MEDLINE, The Cochrane Library, Current Contents/All Editions, EMBASE, Australasian Medical Index and PsychINFO. There was no date restriction applied. In addition, the reference lists of all included studies were scrutinised for other potentially relevant studies.

Selection criteria Systematic reviews of randomised controlled trials (RCTs) and RCTs that compared the effectiveness of nursing interventions and considerations used in the administration of medications via enteral tubes. Other research methods, such as non-randomised controlled trials, longitudinal studies, cohort and case control studies, were also included. Exclusion criteria included studies investigating drug–nutrient interactions or the bioavailability of specific medications.

Data collection and analysis Initial consideration of potential relevance to the review was carried out by the primary author (NP). Two reviewers independently assessed study eligibility for inclusion. A meta-analysis could not be undertaken, as there were no comparable RCTs identified. All data were presented in a narrative summary.

Results There is very limited evidence regarding the effectiveness of nursing interventions in minimising the complications associated with enteral tube medication administration in adults. The review highlights a lack of high quality research on many important nursing issues relating to enteral medication administration. There is huge scope for further research. Some of the evidence that was identified included that nurses should consider the use of liquid form medications as there may be fewer tube occlusions than with solid forms in nasoenteral tubes and silicone percutaneous endoscopic gastronomy tubes. Nurses may need to consider the sorbitol content of some liquid medications, for example, elixirs, as diarrhoea has been attributed to the sorbitol content of the elixir, not the drug itself. In addition, the use of 30 mL of water for irrigation when administering medications or flushing small-diameter nasoenteral tubes may reduce the number of tube occlusions.

Should nurse academics engage in clinical practice?

The education of nurses has traditionally been conducted in the hospital based setting. This changed over the last few decades, with nursing education now being a tertiary based course in many countries. There were numerous reasons for this move, the main goal being to improve the educational experience of students and thus the competence of graduates. Nurse academics whose role is to educate students are faced with the challenge of ensuring their teaching reflects the contemporary nursing environment. One way of doing this is by actively engaging in clinical practice. However there are arguments for and against (as well as barriers to) them doing so and little empirical evidence to support either argument. Individually, nurse academics must make a decision about whether engaging in clinical practice is beneficial to their career and the students they teach.

A systematic review of nursing administration of medication via enteral tubes in adults

Aim. This systematic review aimed to determine the best available evidence regarding the effectiveness of nursing interventions in minimising the complications associated with administering medication via enteral tubes in adults.
Background. Giving enteral medication is a fairly common nursing intervention entailing several skills: verifying tube position, preparing medication, flushing the tube and assessing for potential complications. If not carried out effectively harmful consequences may result leading to increased morbidity and even mortality. Until now, what was considered to be best practice in this area was unknown.
Design. Systematic review.
Methods. CINAHL, MEDLINE, The Cochrane Library, Current Contents/All Editions, EMBASE, Australasian Medical Index and PsychINFO databases were searched up to September 2005. Reference lists of included studies were appraised. Two reviewers independently assessed study eligibility for inclusion. There were no comparable randomised-controlled trials; data
were presented in a narrative summary.
Results. Identified evidence included using 30 ml of water for irrigation when giving medication or flushing small-diameter nasoenteral tubes may reduce tube occlusion. Using liquid medication should be considered as there may be less tube occlusions than with solid forms in nasoenteral tubes and silicone percutaneous endoscopic gastrostomy tubes. In addition, nurses may need to consider the sorbitol content of some liquid medications, for example elixirs, as diarrhoea has been attributed to the sorbitol content of the elixir, not the drug itself.
Conclusion. The evidence was limited. There was a lack of high-quality research on many important issues relating to giving enteral medication.
Relevance to clinical practice. Nurses have the primary responsibility for giving medication through enteral tubes and need knowledge of the best available evidence. Some of the nursing considerations and interventions relating to this skill have been researched in the clinical area and have implications for practice. There is a need for further studies to strengthen these findings.

The tri-focal model of care : Advancing the teaching-nursing home concept

Providing residential aged care is challenging because of the complexity of residents' health status, difficulties recruiting and retaining skilled staff, and financial and regulatory constraints. This paper discusses some of these challenges and describes an innovative model of care, termed 'The Tri-focal model of care'. This model was developed based on the concepts of 'partnership-centred care', 'positive work environment' and the need for evidence-based practice to underpin all aspects of care. It is envisaged that the implementation of this model will provide a rich learning environment that advances the teaching-nursing home concept and the quality of residential aged care.

Practical application of the Delphi technique in a bicultural mental health nursing study in New Zealand

Background. Numerous studies have employed the Delphi technique to seek expert opinion about aspects of clinical practice. When researching literature on the Delphi technique, however, we discovered discrepancies in its application, and a lack of detail when reporting design, administration, and analysis methods. Such lack of specificity hinders the replicability and assessment of the clinical and cultural validity and reliability of Delphi studies.

Aim. The aim of this paper is to detail the practical application of the Delphi technique as a culturally and clinically valid means of accessing expert opinion on the importance of clinical criteria.

Methods. Reference is made to a bicultural New Zealand mental health nursing clinical indicator study that employed a three-round reactive Delphi survey. Equal proportions of Maori and non-Maori nurses (n = 20) and consumers (n = 10) rated the importance of 91 clinical indicator statements for the achievement of professional practice standards. Additional statements (n = 21) suggested by Delphi participants in round 1 were included in subsequent rounds. In round 2, participants explained the rating they applied to statements that had not reached consensus in round 1, and summarized responses were provided to participants in round 3. Consensus was considered to have been achieved if 85% of round 3 ratings lay within a 2-point bracket on the 5-point Likert-scale overall, or in one of the Maori nurse, non-Maori nurse, or consumer groups. A mean rating of 4·5 after round 3 was set as the importance threshold.

Findings. Consensus occurred overall on 75 statements, and within groups on another 24. Most statements (n = 86) reached the importance benchmark.

Conclusions. When rigorous methods of participant selection, group composition, participant feedback, and determination of consensus and importance are employed, the Delphi technique is a reliable, cost-effective means of obtaining and prioritizing experts judgements.

A literature review of the application of the geriatric depression scale, depression anxiety stress scales and post-traumatic stress disorder checklist to community nursing cohorts

Aims and objectives. To explore through literature review the appropriateness of three common tools for use by community nurses to screen war veteran and war widow(er) clients for depression, anxiety and post-traumatic stress disorder.

Background. War veterans and, to a lesser extent, war widow(er)s, are prone to mental health challenges, especially depression, anxiety and post-traumatic stress disorder. Community nurses do not accurately identify such people with depression and related disorders although they are well positioned to do so. The use of valid and reliable self-report tools is one method of improving nurses' identification of people with actual or potential mental health difficulties for referral to a general practitioner or mental health practitioner for diagnostic assessment and treatment. The Geriatric Depression Scale, Depression Anxiety Stress Scales and Post-traumatic Stress Disorder Checklist are frequently recommended for mental health screening but the appropriateness of using the tools for screening war veteran and war widow(er) community nursing clients who are often aged and have functional impairment, is unknown.

Design. Systematic review.

Conclusions. Current literature informs that the Geriatric Depression Scale accurately predicts a diagnosis of depression in community nursing cohorts. The three Depression Anxiety Stress Scales subscales of depression, anxiety and stress are valid; however, no studies were identified that compared the performance of the Depression Anxiety Stress Scales in predicting diagnoses of depression or anxiety. The Post-traumatic Stress Disorder Checklist predicts post-traumatic stress disorder in community cohorts although no studies meeting the selection criteria included male participants.

Relevance to clinical practice. This review provides recommendations for the use of the Geriatric Depression Scale, Depression Anxiety Stress Scales and The Post-traumatic Stress Disorder Checklist based on examination of the published evidence for the application of these screening tools in samples approximated to community nursing cohorts. Findings and recommendations would guide community nurses, managers and health planners in the selection of mental health screening tools to promote holistic community nursing care.

Does an evidence-based sedation protocol improve practice and patient outcomes in critical care?

Learning Objective 1: compare protocol-directed sedation management with traditional non-protocol-directed practice in mechanically ventilated patients in an Australian critical care.

Learning Objective 2: explain the contrasting international research findings on sedation protocol implementation.
Minimization of sedation in critical care patients has recently received widespread support. Professional organizations internationally have published sedation management guidelines for critically ill patients to improve the use of research in practice, decrease practice variability and shorten mechanical ventilation duration. Innovations in practice have included the introduction of decision making protocols, daily sedation interruptions and new drugs and monitoring technologies. The aim of this study was to compare protocol-directed sedation management with traditional non-protocol-directed practice in mechanically ventilated patients in an Australian critical care setting.

A randomized, controlled trial design was used to study 312 mechanically ventilated adult patients in a general critical care unit at an Australian metropolitan teaching hospital. Patients were randomly assigned to receive protocol directed sedation management developed from evidence based guidelines (n=153) or usual clinical practice (n=159).

The median (95% CI) duration of ventilation was 58 hrs (44–78 hrs) for patients in the non-protocol group and 79 hrs (56–93) for those patients in the protocol group (p=0.20). Results were not significant for length of stay in critical care or hospital, the frequency of tracheostomies, and unplanned extubations. A Cox proportional hazards model estimated that protocol directed sedation management was associated with a 22% decrease (95% CI: 40% decrease to 2% increase, p=0.07) in the occurrence of successful weaning from mechanical ventilation.

Few randomized controlled trials have evaluated the effectiveness of protocol-directed sedation outside of North America. This study highlights the lack of transferability between different settings and different models of care. Qualified, high intensity nursing in the Australian critical care setting facilitates rapid, responsive decisions for sedation management and an increased success rate for weaning from mechanical ventilation.

Action research in cooperative education projects : developing lifelong capabilities for improving practice

There are natural synergies between action research as a method of inquiry and the practice of cooperative education. In the search to integrate theory and practice, action research is underpinned by a philosophy of experiential learning. Similarly, cooperative education is underpinned by the belief that in order to learn, there also needs to be action. The work of cooperative education students is also founded on data-based reflection is highly context based and usually collaborative; important characteristics of action research (Cardno, 2003). These similarities between action research and cooperative education provide a starting point in conceptualizing the adoption of action research for sport cooperative education projects. How can action research be integrated within cooperative education projects? This paper will discuss the theoretical basis of action research and illustrate through the use of case studies why and how action research has been utilized in cooperative education projects in sport and recreation. Sport students undertake a range of activities in the cooperative education setting. Some complete basic day to day tasks in recreation centers and with sports teams and others act as volunteers in major events. While these types of roles can fulfill desired outcomes for cooperative education program (for student, industry organization and institution), the adoption of action research can add a further dimension because it aims to create change within the setting under investigation. Through the use of cooperative education projects, students are in a unique position to frame a problem, integrate theory, determine action, and implement and evaluate that action. This paper explores how action research is used in cooperative education projects to help develop capabilities for improving practice.
