The IUCN red list of ecosystems: motivations, challenges, and applications

In response to growing demand for ecosystem-level risk assessment in biodiversity conservation, and rapid proliferation of locally tailored protocols, the IUCN recently endorsed new Red List criteria as a global standard for ecosystem risk assessment. Four qualities were sought in the design of the IUCN criteria: generality; precision; realism; and simplicity. Drawing from extensive global consultation, we explore trade-offs among these qualities when dealing with key challenges, including ecosystem classification, measuring ecosystem dynamics, degradation and collapse, and setting decision thresholds to delimit ordinal categories of threat. Experience from countries with national lists of threatened ecosystems demonstrates well-balanced trade-offs in current and potential applications of Red Lists of Ecosystems in legislation, policy, environmental management and education. The IUCN Red List of Ecosystems should be judged by whether it achieves conservation ends and improves natural resource management, whether its limitations are outweighed by its benefits, and whether it performs better than alternative methods. Future development of the Red List of Ecosystems will benefit from the history of the Red List of Threatened Species which was trialed and adjusted iteratively over 50 years from rudimentary beginnings. We anticipate the Red List of Ecosystems will promote policy focus on conservation outcomes in situ across whole landscapes and seascapes.

The relationship between personality traits and psychotic like experiences in a large non-clinical adolescent sample

Objective: The relationship between personality and psychosis is well established. It has been suggested that this relationship may be partly accounted for by higher levels of depression in individuals with certain personality traits. We explored whether the link between personality and psychotic symptoms is already apparent in adolescence, and if this association would still hold when depression was controlled for. Method: 654 secondary school students were surveyed via self-report questionnaires measuring the Five-Factor model of personality (NEO-FFI), depression (CES-D) and psychotic-like experiences (CAPE). Results: Positive associations were found between Neuroticism and all CAPE-subscales except Magical Thinking, which was in turn associated with all other personality traits when at high levels. Agreeableness was negatively associated with all CAPE-subscales, while Openness to Experience was only positively associated with Persecutory Ideas and Magical Thinking. After controlling for depression, many of the significant associations remained. Conclusion: Our findings suggest that the chance of having psychotic like experiences is more likely for adolescents with certain personality traits. These associations are not fully explained by depression, especially when psychotic experiences are at higher levels. Future research is needed to investigate if these personality traits might put a person at risk for the development of full-blown psychosis.

Landscaping on shifting ground: teacher education in a digitally transforming world

For almost three decades, the landscape of teacher education has been modestly shaped by the exploration of practices that made use of what were, at the time, current instances of computing and communication technologies (CCTs). More broadly and importantly however, the deployment of CCTs globally has, over the same time period (1980-2008), supported a reshaping of the planet's social, economic and political circumstances in which all forms of education operate. Despite the enormity of these shifts the focus in teacher education has remained largely at site, reflecting a similar focus in schools. In fact, the patterns of adaption and response in teacher education to each new instance of high-tech product are now quite predictable. Thus, while teacher education's engagement with CCTs can be mapped as a kind of minor landscaping, a process which attends more to appearance than substance, it is landscaping effectively premised upon a stable geography, one that resembles that of thirty years ago. This paper explores the changed and changing geography of a world heavily shaped by the ongoing deployment and use of more and more powerful CCTs. The analysis suggests that if we continue to attend only to landscaping, teacher education will be at risk of being terraformed.

Novel design of a renewable energy remote laboratory

BACKGROUND OR CONTEXT: Current work in remote laboratories focuses on student interaction in a setting that can be at times disconnected from real world systems. Laboratories have been developed that show models of a working system, focusing on a single aspect, but very few laboratories allow the user to see the outputs of a working system that interacts with the real world as would be expected outside of a laboratory setting. It was aimed with this paper to show a design of a novel approach to building a remote laboratory that would be able to interact with a fully functional renewable energy system, and to show the students the outputs of such a system in real time. It allows for the user to be presented with information in a new context.
PURPOSE OR GOAL: With this research it is hoped to achieve a remote laboratory that will be able to present students with the data from a renewable energy system live, as it is generated as well as all the logged date generated. It is aimed with this novel approach to building a remote laboratory to assist the students in learning about renewable energy systems while allowing the student to access real data, instead of simulated data. Links to increased motivation due to realism in data given as well as change in student perception on learning in remote laboratories mean that a system such as this could change the way students approach learning about renewable energy generation systems. This will require further research however.
APPROACH: This remote laboratory required gathering data from an already established system. The live results were not recorded, and a log file was generated daily, however this was not fast enough to give to students as it was generated, so a system that could maintain communication between all systems, while also polling for data itself was required. In addition to this, the system had to communicate to a server that would give students access to the live data. The server was set up in such a way that students were not required to install any programs on their computer, multiple students could access the data at any given time, and a wide range of devices, including mobile devices, could all access the remote laboratory.
DISCUSSION: Key outcomes include the design of the remote laboratory, including screenshots of data acquisition from the renewable energy system from different devices. The design is split into two sections, one covering the server side architecture while another covers the data acquisition architecture. A very brief discussion on students’ initial interaction is also undertaken.
RECOMMENDATIONS/IMPLICATIONS/CONCLUSION: Research has shown that the degree of realism in remote education can have an effect on students’ behaviors/motivation in a remote laboratory. By allowing students to knowingly access a real system that is currently being used to generate power from renewable energy sources, the methods and motivations that students use when approaching renewable energy systems may change.

Automatic generation of traditional style painting by using density-based color clustering

In this paper, a novel approach is proposed to automatically generate both watercolor painting and pencil sketch drawing, or binary image of contour, from realism-style photo by using DBSCAN color clustering based on HSV color space. While the color clusters produced by proposed methods help to create watercolor painting, the noise pixels are useful to generate the pencil sketch drawing. Moreover, noise pixels are reassigned to color clusters by a novel algorithm to refine the contour in the watercolor painting. The main goal of this paper is to inspire non-professional artists' imagination to produce traditional style painting easily by only adjusting a few parameters. Also, another contribution of this paper is to propose an easy method to produce the binary image of contour, which is a vice product when mining image data by DBSCAN clustering. Thus the binary image is useful in resource limited system to reduce data but keep enough information of images. © 2007 IEEE.

Does a combination of virtual reality, neuromodulation and neuroimaging provide a comprehensive platform for neurorehabilitation? - A narrative review of the literature

In the last decade, virtual reality (VR) training has been used extensively in video games and military training to provide a sense of realism and environmental interaction to its users. More recently, VR training has been explored as a possible adjunct therapy for people with motor and mental health dysfunctions. The concept underlying VR therapy as a treatment for motor and cognitive dysfunction is to improve neuroplasticity of the brain by engaging users in multisensory training. In this review, we discuss the theoretical framework underlying the use of VR as a therapeutic intervention for neurorehabilitation and provide evidence for its use in treating motor and mental disorders such as cerebral palsy, Parkinson’s disease, stroke, schizophrenia, anxiety disorders, and other related clinical areas. While this review provides some insights into the efficacy of VR in clinical rehabilitation and its complimentary use with neuroimaging (e.g., fNIRS and EEG) and neuromodulation (e.g., tDCS and rTMS), more research is needed to understand how different clinical conditions are affected by VR therapies (e.g., stimulus presentation, interactivity, control and types of VR). Future studies should consider large, longitudinal randomized controlled trials to determine the true potential of VR therapies in various clinical populations.

Biologically inspired vector fields to generate hair directions

This paper describes how biologically inspired vector fields can be used to partially automate the manual and time-consuming process of specifying hair directions. This approach replicates the consequence of stretching of skin from natural hair development process, in contrast to replicating the appearance of hair. The direction of each hair on the surface of an arbitrary 3D model is determined by interpolating the solution vector field that satisfies a set of user-defined constraints describing the stretching of skin. Results found that the generated hair directional pattern closely resembles that found naturally. Further investigation revealed that the presence of naturally occurring hair types and the varying distribution of hair directions induced by the calculated vector field enhanced the realism of hair coats generated using this approach. Aside from hair or fur, this approach can also be applied to hair-like masses such as grass, feathers, or scales.

Re-processing The Mystical Rose

This essay explores the animation practice of Australian filmmaker Michael Lee, whose career spans the late 60s to the present. His notoriously dissident and innovative feature length work The Mystical Rose (1976, 65 minutes) is the primary focus, the fulcrum point of an analysis balanced by a review of his earlier shorter formative films, his cultural milieu, the thinkers that shaped his youth and particularly his changing relation to the Catholic Church. This relationship with Christianity has gone full circle through a critical rejection, worked through in The Mystical Rose, to a re-embrace in his later films Turnaround (1983, 60 mins) and The Contemplation of the Cross (1989, 27 minutes). This trajectory is understood here in relation to Magic Realism, Michael Bakhtin’s conception of the ‘Carnivalesque’ and Surrealism. What is of particular interest historically for animation is Lee’s pioneering innovative combination of animation with live action documentation, conveying both inner and outer realities, and mapping the relationships between them.

Sadae (Serving the Great) in Korea–great power(s) relations since 1392

Based on detailed analysis of the historical records that documented Korea’s relations with the great powers since 1392, the research finds that a balanced approach that combines constructivism and realism can better analyse, in addition to state security, the historical complexity and cultural nuance in the Northeast Asian international relations.

Teacher professional learning in early childhood education: insights from a mentoring program

In Australia, as is the case in other countries around the world, the Early Childhood workforce is in the process of ‘skilling up’ to meet government demands related to quality service provision. This paper sets out to identify what constitutes effective teacher professional learning through mentoring. Guided by critical realism and social practice as theoretical perspectives, the paper uses data drawn from the State-wide Professional Mentoring Program for Early Childhood Teachers (2011–2014), Victoria, Australia. The findings identify four C’s essential to effective professional learning – Context: the association between individual aspirations and systemic requirements; Collegiality: the positioning and importance of collegial relationships; Criticality: critical deliberation in ‘safe’ learning environments; and Change: recognition that teacher learning takes place in the domains of professional dispositions, pedagogical knowledge and social capital. These findings point to the need to consider teachers’ contexts of practice in the design of professional development programs such as mentoring, and to conceptualise learning as a socially situated practice rather than a detached pedagogic event.
