In a study of socioeconomically disadvantaged children's acquisition of school literacies, a university research team investigated how a group of teachers negotiated critical literacies and explored notions of social power with elementary children in a suburban school located in an area of high poverty. Here we focus on a grade 2/3 classroom where the teacher and children became involved in a local urban renewal project and on how in the process the children wrote about place and power. Using the students' concerns about their neighborhood, the teacher engaged her class in a critical literacy project that not only involved a complex set of literate practices but also taught the children about power and the possibilities for local civic action. In particular, we discuss examples of children's drawing and writing about their neighborhoods and their lives. We explore how children's writing and drawing might be key elements in developing "critical literacies" in elementary school settings. We consider how such classroom writing can be a mediator of emotions, intellectual and academic learning, social practice, and political activism.

Purpose This study investigates the effects of service innovation exploration-exploitation on financial performance through the delivery of quality services. Additional emphasis is also given to examining the extent to which employee empowerment and slack resources enhance or suppress the performance benefits of service firms engaging in service innovation exploration versus exploitation. Design/methodology/approach Data were drawn from a multi-informant survey of service firms using a drop-and-collect approach. The survey gathered data from managers, customer service employees and customers to test the hypotheses. Findings The results show that excelling at both exploitative and exploratory innovation helps enhance the quality of services, which in turn yield superior financial performance. Further, empowering employees enhances the relationship between exploratory and exploitative service innovation and service quality. We also show that the extent managers’ perceived their market to be competitive influences in the pursuit of high levels of both service innovation exploration and exploitation and that this relationship is impacted by the extent they believe they have available slack resources. Practical implications The findings suggest that service firms need to pursue both exploitation and exploration at high levels simultaneously and empower their employees to stay ahead of competitors in delivering quality services, which ultimately contribute to the achievement of superior financial outcomes. Also, the findings highlight the importance of employee empowerment, market competitiveness and slack resources in the pursuit of high levels of both service innovation exploration and exploitation. Originality/value These findings and our theory indicate that this study is the first to empirically examine organizational ambidexterity in the context of service innovation exploration – exploitation adopting the principles of combined and balanced innovation. The study provides insights into the critical role of customers’ perceptions of service quality in contributing to firms’ financial performance. Our insights are unique in that the study incorporates managers, employees and customers in an integrated service innovation model.

The synthesis of organoclays (OC) by intercalation of quaternary ammonium cation (QAC) into expanding clay minerals, notably montmorillonite (Mt), has attracted a great deal of attention during the past two decades. The OC have also found applications in the manufacture of clay polymer nanocomposites (CPN) and environmental remediation. Despite the wealth of information that exists on the formation and properties of OC, some problems remain to be resolved. The present contribution is an attempt at clarifying two outstanding issues, based on the literature and experimental data obtained by the authors over the past years. The first issue concerns the relationship between the cation exchange capacity (CEC) of the Mt and the basal spacing of the OC which, in turn, is dependent on the concentration and the nature of the added QAC. At a concentration less than 1 CEC, organo-Mt (OMt) formed using the QAC with a short alkyl chain length with nc < 16 (e.g., dodecyl trimethylammonium) gives basal spacings of 1.4–1.6 nm that are essentially independent of the CEC. However, for long-chain QAC with nc ≥ 16 (e.g., hexadecyl trimethylammonium), the basal spacing varies with the QAC concentration. For Mt with a CEC of 80–90 meq/100 g, the basal spacing of the OC increases gradually with the CEC and shows a sudden (stepwise) increase to 3.2–3.8 nm at a QAC concentration of 1.5 CEC and to 3.5–4.0 nm at a concentration of 2.0 CEC. The second issue pertains to the “locking” effect in QAC- and silane-modified pillared interlayered clays (PILC) and Mt. For silylated Mt, the “locking” effect results from the covalent bonding of silane to two adjacent layers within a single clay mineral particle. The same mechanism can operate in silane-grafted PILC but in this case, the “locking” effect may primarily be ascribed to the pillaring of adjacent basal surfaces by metal hydr(oxides).

This research explored the transition to palliative care process through critical analysis of the experiences of patients diagnosed with metastatic melanoma, family carers and health professionals. The outcomes depict a complex intersection between acute care services and palliative care where the discipline of palliative care struggled to position itself within a highly specialised health system. The findings indicate uncertainty around scopes of practice with ambiguity and tension around the transition to palliative care. The research thus argues for stronger and more coherent partnerships and a critical and interdisciplinary conversation about the positioning of palliative care in the acute care sector.

This chapter investigates the capacity of a well-supported holistic ePortfolio program, the QUT Student ePortfolio Program (QSeP), to support critical reflection for pedagogic innovation in higher education, by exploring practice examples. The chapter looks across faculty and discipline areas to illustrate a range of ePortfolio learning case studies, which have led pedagogical innovation across a whole institution, to enhance student learning and support academic teaching. The ePortfolio strategies discussed support innovation in learning and teaching where academics use the ePortfolio approach in different ways to develop connectedness (productive pedagogies) within learning. Students are supported to develop awareness of the connections between formal and informal learning opportunities and between their learning and personal and professional goals. Students are guided to understand what they have learned and how they have learned in terms of generic employability skills or graduate attributes and also in relation to professional standards and competencies and personal goals. In essence, the ePortfolio-supported pedagogy creates capstone events enabling students to develop a professional identity and understanding of ongoing professional development. The examples are drawn from distinct discipline areas and illustrate the capacity of ePortfolio to underpin pedagogic innovation across discipline areas: • Bachelor of Information Technology—the ePortfolio approach supports students to explore the IT industry as a means of clarifying personal expectations and goals, thereby enhancing student potential in the course c• Bachelor of Nursing and Master of Nursing Science—students develop a professional ePortfolio to show development of the nursing competencies • Master of Information Technology—Library and Information students compile a Professional Portfolio for assessment in the Professional Practice subject • Bachelor of Laws—Virtual Law Placement (VLP) is a unit of study that challenges students to critically reflect on their performance and development duringthe work placement Each case study illustrates the academic teaching goal and student ePortfolio task in context. Issues, challenges and support strategies are identified. Comments from the students and their lecturers give an indication of the effectiveness of the ePortfolio approach to meet learning and teaching goals.

In contrast to single robotic agent, multi-robot systems are highly dependent on reliable communication. Robots have to synchronize tasks or to share poses and sensor readings with other agents, especially for co-operative mapping task where local sensor readings are incorporated into a global map. The drawback of existing communication frameworks is that most are based on a central component which has to be constantly within reach. Additionally, they do not prevent data loss between robots if a failure occurs in the communication link. During a distributed mapping task, loss of data is critical because it will corrupt the global map. In this work, we propose a cloud-based publish/subscribe mechanism which enables reliable communication between agents during a cooperative mission using the Data Distribution Service (DDS) as a transport layer. The usability of our approach is verified by several experiments taking into account complete temporary communication loss.

Fast restoration of critical loads and non-black-start generators can significantly reduce the economic losses caused by power system blackouts. In a parallel power system restoration scenario, the sectionalization of restoration subsystems plays a very important role in determining the pickup of critical loads before synchronization. Most existing research mainly focuses on the startup of non-black-start generators. The restoration of critical loads, especially the loads with cold load characteristics, has not yet been addressed in optimizing the subsystem divisions. As a result, sectionalized restoration subsystems cannot achieve the best coordination between the pickup of loads and the ramping of generators. In order to generate sectionalizing strategies considering the pickup of critical loads in parallel power system restoration scenarios, an optimization model considering power system constraints, the characteristics of the cold load pickup and the features of generator startup is proposed in this paper. A bi-level programming approach is employed to solve the proposed sectionalizing model. In the upper level the optimal sectionalizing problem for the restoration subsystems is addressed, while in the lower level the objective is to minimize the outage durations of critical loads. The proposed sectionalizing model has been validated by the New-England 39-bus system and the IEEE 118-bus system. Further comparisons with some existing methods are carried out as well.

In a series of publications over the last decade, Australian National University Professor Margaret Thornton has documented a disturbing change in the nature of legal education. This body of work culminates in a recently published book based on interviews with 145 legal academics in Australia, the United Kingdom, New Zealand and Canada. In it, Thornton describes a feeling of widespread unease among legal academics that society, government, university administrators and students themselves are moving away from viewing legal education as a public good which benefits both students and society. Instead, legal education is increasingly being viewed as a purely private good, for consumption by the student in the quest for individual career enhancement.

This thesis evaluates the recent work of the Organisation for Economic Cooperation and Development and civil society groups in creating requirements for multinational entities to disclose financial information on a Country-by-Country basis. Country-by-Country reports may identify profit-shifting activities and enable various stakeholders to hold multinational entities accountable for their global conduct, through the provision of transparent and decision-useful information. This thesis identifies inadequacies in current disclosure requirements and develops a standardised Country-by-Country model, which is applied to the disclosures of three multinational entities to illustrate its pragmatic feasibility and the improvement in quality of financial information available to users.

Anthony Dunne’s Hertzian Tales is an exploration of the aesthetic and conceptual aspects of industrial design and its potential to bring about social change for the users of electronic objects. It is a provoking and – to first-time readers – positively alarming social commentary on the interrelationship between electronic product design and culture, and the powerful but largely under-explored potential of electronic innovation to trigger social awareness. Hertzian Tales proposes an innovative approach to critical design and therefore serves as a reflection on and a critique of the commercial design practices at large. In this second edition, Dunne reiterates the original rationale for his project: a concern that the majority of industrial designers have unwittingly joined a treadmill culture of post-industrial mass-production – turning out electronic goods that have long simply met the brief of an optimally functioning and eagerly consumable technology.

This paper identifies critical beliefs underpinning intentions to commence and continue plasmapheresis donation. Whole blood (n = 624) and first-time plasmapheresis (n = 460) donors completed a cross-sectional survey assessing the belief-base of the theory of planned behaviour and rated their plasmapheresis donation intentions. While the idea of red blood cells being returned was a key deterrent for all donors, critical beliefs underlying commencement and continuation in the plasmapheresis donor panel differed and varied as a function of blood donation history. Findings will assist the development of targeted persuasion messages to optimise recruitment and retention of plasmapheresis donors in a non-remunerated context.

Parkinson’s disease is a common neurodegenerative disorder with a higher risk of hospitalization than the general population. Therefore, there is a high likelihood of encountering a person with Parkinson’s disease in acute or critical care. Most people with Parkinson’s disease are over the age of 60 years and are likely to have other concurrent medical conditions. Parkinson’s disease is more likely to be the secondary diagnosis during hospital admission. The primary diagnosis may be due to other medical conditions or as a result of complications from Parkinson’s disease symptoms. Symptoms include motor symptoms, such as slowness of movement and tremor, and non-motor symptoms, such as depression, dysphagia, and constipation. There is a large degree of variation in the presence and degree of symptoms as well as in the rate of progression. There is a range of medications that can be used to manage the motor or non-motor symptoms, and side effects can occur. Improper administration of medications can result in deterioration of the patient’s condition and potentially a life-threatening condition called neuroleptic malignant-like syndrome. Nutrients and delayed gastric emptying may also interfere with intestinal absorption of levodopa, the primary medication used for motor symptom management. Rates of protein-energy malnutrition can be up to 15 % in people with Parkinson’s disease in the community, and this is likely to be higher in the acute or critical care setting. Nutrition-related care in this setting should utilize the Nutrition Care Process and take into account each individual’s Parkinson’s disease motor and non-motor symptoms, the severity of disease, limitations due to the disease, medical management regimen, and nutritional status when planning nutrition interventions. Special considerations may need to be taken into account in relation to meal and medication times and the administration of enteral feeding. Nutrition screening, assessment, and monitoring should occur during admission to minimize the effects of Parkinson's disease symptoms and to optimise nutrition-related outcomes.

The growing call for physical educators to move beyond the bounds of performance has been a powerful discourse. However, it is a discourse that has tended to be heavy on theory but light on practical application. This paper discusses recent work in the area of skill acquisition and what this might mean for pedagogical practices in physical education. The acquisition of motor skill has traditionally been a core objective for physical educators, and there has been a perception that child-centred pedagogies have failed in the achievement of this traditional yardstick. However, drawing from the work of Rovegno and Kirk (1995) and Langley (1995; 1997), and making links with current work in the motor learning area, it is possible to show that skill acquisition is not necessarily compromised by child-centred pedagogy. Indeed, working beyond Mosston's discovery threshold and using models such as Games for Understanding, can provide deeper skill-learning experiences as well as being socially just.
