Autonomous Fault Detection in Self-Healing Systems using Restricted Boltzmann Machines

Autonomously detecting and recovering from faults is one approach for reducing the operational complexity and costs associated with managing computing environments. We present a novel methodology for autonomously generating investigation leads that help identify systems faults, and extends our previous work in this area by leveraging Restricted Boltzmann Machines (RBMs) and contrastive divergence learning to analyse changes in historical feature data. This allows us to heuristically identify the root cause of a fault, and demonstrate an improvement to the state of the art by showing feature data can be predicted heuristically beyond a single instance to include entire sequences of information.Comment: Published and presented in the 11th IEEE International Conference and Workshops on Engineering of Autonomic and Autonomous Systems (EASe 2014

Building Resilience through Culturally Grounded Practices in Clinical Psychology and Higher Education

There is no “one size fits all” approach when it comes to the process of healing, particularly for individuals who are continuously affected by the many barriers and impacts of systemic oppres- sion. This reality demands the sustained development of a praxis rooted in trauma-informed and culturally grounded care so that we may better serve our most-impacted communities (such as Black, Indigenous and People of Color [BIPOC], disability, queer, and survivor communities). As practitioners in the fields of Clinical Psychology and Higher Education, we engage in cross-disciplinary analysis so that we may amplify and share our tools for collective healing. We highlight the importance of sup- porting client and student development through multisystemic and resilience-oriented frameworks. Specifically, we discuss the implications of the Minority Stress Model (Meyer, 2003) and Bronfenbrenner’s Ecological Systems Theory (1979) in serving our communities more effectively to enhance positive clinical and academic outcomes

mRUBiS: An Exemplar for Model-Based Architectural Self-Healing and Self-Optimization

Self-adaptive software systems are often structured into an adaptation engine that manages an adaptable software by operating on a runtime model that represents the architecture of the software (model-based architectural self-adaptation). Despite the popularity of such approaches, existing exemplars provide application programming interfaces but no runtime model to develop adaptation engines. Consequently, there does not exist any exemplar that supports developing, evaluating, and comparing model-based self-adaptation off the shelf. Therefore, we present mRUBiS, an extensible exemplar for model-based architectural self-healing and self-optimization. mRUBiS simulates the adaptable software and therefore provides and maintains an architectural runtime model of the software, which can be directly used by adaptation engines to realize and perform self-adaptation. Particularly, mRUBiS supports injecting issues into the model, which should be handled by self-adaptation, and validating the model to assess the self-adaptation. Finally, mRUBiS allows developers to explore variants of adaptation engines (e.g., event-driven self-adaptation) and to evaluate the effectiveness, efficiency, and scalability of the engines

Automatic Software Repair: a Bibliography

This article presents a survey on automatic software repair. Automatic software repair consists of automatically finding a solution to software bugs without human intervention. This article considers all kinds of repairs. First, it discusses behavioral repair where test suites, contracts, models, and crashing inputs are taken as oracle. Second, it discusses state repair, also known as runtime repair or runtime recovery, with techniques such as checkpoint and restart, reconfiguration, and invariant restoration. The uniqueness of this article is that it spans the research communities that contribute to this body of knowledge: software engineering, dependability, operating systems, programming languages, and security. It provides a novel and structured overview of the diversity of bug oracles and repair operators used in the literature

Trauma-informed services and trauma-specific care for Indigenous Australian children

This paper examines how childhood trauma experienced by Indigenous children can be overcome by appropriate interventions.IntroductionWhile many Indigenous and non-Indigenous Australian children grow up in safe homes and live in safe communities, there are some who do not. In the case of Indigenous children, some families and communities are unable to, or are still working to, heal the trauma of past events, including displacement from Country, institutionalisation and abuse. The Stolen Generations also represent a significant cause of trauma. In 2008, an estimated 8% of Indigenous people aged 15 and over reported being removed from their natural family and 38% had relatives who had been removed from their natural family. This trauma can pass to children (inter-generational trauma).Indigenous children may also experience a range of distressing life events including illness and accidents, hospitalisation or death of close family members, exposure to violence, family disintegration (with kin networks fragmented due to forced removals, relationship breakdown and possibly incarceration) and financial stress.Experiencing trauma in childhood can have severe and long-lasting effects; effects that can be overcome by appropriate interventions. This resource sheet examines these effects and explores how they can be tackled. It focuses on the design and delivery of trauma-informed and trauma-specific children’s services and care

Relationships and implications for complementary and alternative medicine in Aotearoa New Zealand: A discussion paper

The purpose of this paper is to initiate a discussion on contextualising the relationship between the nursing profession and complementary and alternative medicine (CAM) within Aotearoa New Zealand. There is limited research and data linking complementary and alternative medicine to nursing or how this could be integrated into health care delivery. The authors’ intentions are to raise awareness of a trend within health and wellness that could have implications for the nursing profession in Aotearoa New Zealand. Existing knowledge from overseas research is discussed to raise awareness on complementary and alternative medicine knowledge and any perceptions or educational needs nurses may require when considering the utilisation of complementary and alternative medicine. A range of questions are presented aimed at highlighting areas of development and future research for nursing in Aotearoa New Zealand if complementary and alternative medicine therapies or theory are applied within mainstream health care settings.

GRIDKIT: Pluggable overlay networks for Grid computing

A `second generation' approach to the provision of Grid middleware is now emerging which is built on service-oriented architecture and web services standards and technologies. However, advanced Grid applications have significant demands that are not addressed by present-day web services platforms. As one prime example, current platforms do not support the rich diversity of communication `interaction types' that are demanded by advanced applications (e.g. publish-subscribe, media streaming, peer-to-peer interaction). In the paper we describe the Gridkit middleware which augments the basic service-oriented architecture to address this particular deficiency. We particularly focus on the communications infrastructure support required to support multiple interaction types in a unified, principled and extensible manner-which we present in terms of the novel concept of pluggable overlay networks

Healing the Hurt: Trauma-Informed Approaches to the Health of Boys and Young Men of Color

From discrimination and poverty to alcoholism and assault, trauma in its varied forms plays a major part in the lives of Latino and African-American boys and young men. This paper outlines the ways in which violence prevention, family support, health care, foster care, and juvenile justice can incorporate a trauma-informed approach to improve the physical and mental health of young men and boys

A component-based middleware framework for configurable and reconfigurable Grid computing

Significant progress has been made in the design and development of Grid middleware which, in its present form, is founded on Web services technologies. However, we argue that present-day Grid middleware is severely limited in supporting projected next-generation applications which will involve pervasive and heterogeneous networked infrastructures, and advanced services such as collaborative distributed visualization. In this paper we discuss a new Grid middleware framework that features (i) support for advanced network services based on the novel concept of pluggable overlay networks, (ii) an architectural framework for constructing bespoke Grid middleware platforms in terms of 'middleware domains' such as extensible interaction types and resource discovery. We believe that such features will become increasingly essential with the emergence of next-generation e-Science applications. Copyright (c) 2005 John Wiley & Sons, Ltd
