Transit route occupancy load factor and passenger average travel time for quality of service assessment

This paper investigates quality of service (QoS) and resource productivity implications of transit route passenger loading and travel time. It highlights the value of occupancy load factor as a direct passenger comfort QoS measure. Automatic Fare Collection data for a premium radial bus route in Brisbane, Australia, is used to investigate time series correlation between occupancy load factor and passenger average travel time. Correlation is strong across the entire span of service in both directions. Passengers tend to be making longer, peak direction commuter trips under significantly less comfortable conditions than off-peak. The Transit Capacity and Quality of Service Manual uses segment based load factor as a measure of onboard loading comfort QoS. This paper provides additional insight into QoS by relating the two route based dimensions of occupancy load factor and passenger average travel time together in a two dimensional format, both from the passenger’s and operator’s perspectives. Future research will apply Value of Time to QoS measurement, reflecting perceived passenger comfort through crowding and average time spent onboard. This would also assist in transit service quality econometric modeling. The methodology can be readily applied in a practical setting where AFC data for fixed scheduled routes is available. The study outcomes also provide valuable research and development directions.

How Jung's concept of the wounded healer can guide learning and teaching in social work and human services

The concept of the “wounded healer” has been used to explain why those with adverse childhood histories often enter helping professions such as social work and human services (SWHS). Psychotherapist Carl Jung (1875–1961) believed wounded healers developed insight and resilience from their own experiences, enabling transformative interventions to occur with clients. Concerns exist that students with adverse childhood histories in SWHS may display unresolved emotional issues. This journal article explores how Jung’s interpretation of the wounded healer can be critically applied to understanding the learning needs of SWHS students with histories of abuse, neglect or other childhood adversity. The relevance of the wounded healer to SWHS education is explored in three key areas: - 1) the increased possibility of the occurrence of countertransference; - 2) the potential for vicarious traumatisation and burnout, and; - 3) personal and professional resilience displayed by SWHS students with a history of childhood adversity. The wounded healer metaphor allows for a more nuanced understanding of SWHS students with these histories. It also provides insight into the pedagogical considerations associated with teaching this student cohort.

A collaborative multi-agent based conference planner application using web and grid services

Distributed Collaborative Computing services have taken over centralized computing platforms allowing the development of distributed collaborative user applications. These applications enable people and computers to work together more productively. Multi-Agent System (MAS) has emerged as a distributed collaborative environment which allows a number of agents to cooperate and interact with each other in a complex environment. We want to place our agents in problems whose solutions require the collation and fusion of information, knowledge or data from distributed and autonomous information sources. In this paper we present the design and implementation of an agent based conference planner application that uses collaborative effort of agents which function continuously and autonomously in a particular environment. The application also enables the collaborative use of services deployed geographically wide in different technologies i.e. Software Agents, Grid computing and Web service. The premise of the application is that it allows autonomous agents interacting with web and grid services to plan a conference as a proxy to their owners (humans). © 2005 IEEE.

Field placement and the impact of financial stress on social work and human services students

While significant research has been undertaken exploring the pedagogical benefits of undertaking lengthy social work and human services field placements, there has been very little consideration regarding the potential financial stress involved for students. This study has addressed this knowledge gap. Research was conducted in 2014 using quantitative and qualitative methods with students, academic and professional staff from six Queensland Universities. The findings show a significant relationship between unpaid placements and financial hardship creating considerable stress for students and at times a compromised learning experience whilst on placement. The limited flexibility in the requirements of professional bodies and universities for how placements are undertaken has been identified as a key contributor to financial hardship. Addressing the complexities inherent in this issue requires a collaborative effort from multiple stakeholders and should not be regarded as a problem for students to endure and manage.

A submission to the Tasmanian Department of Health and Human Services consultation “Healthy Tasmania Five Year Strategic Plan”

This submission will address a number of questions raised in section 5.2, “Potential Future Initiatives to target smoking”, of the Healthy Tasmania Five Year Strategic Plan – Community Consultation Draft. Each question has been answered within this submission. This submission will also address the possibility of legal challenges to these proposed changes, a pivotal consideration when implementing any tobacco control laws. This is due to the aggressive nature of the tobacco industry, as illustrated by their attempts to challenge plain packaging laws in the country and through international treaties. The evidence provided in my submission illustrates that prevention of initiation of smoking during adolescence has various benefits in terms of reduction of negative smoking behaviors in later life. I argue that increasing the minimum legal age of purchasing for tobacco to 21 will benefit both the levels of underage smoking as well as the age of onset of initiation of smoking, due to the greater difficulties that those who are underage would experience in accessing tobacco products. I will also address the question of whether the minimum smoking age should be increased to 25.

Family mediation and women’s services: Towards effective referral

Central to Government’s strategy for separating families is the management and resolution of disputes away from courts and litigation processes wherever this is achievable. A key group of players in facilitating this vision are workers within the wide range of women’s services. This study surveyed workers at a number of Victorian women’s services that provide advice, support, and referral for women and explored their understanding of mediation processes and outcomes. The results indicate that, while generally supportive of mediation as a process that could assist their clients, workers were concerned about its appropriateness when family violence was an issue. Some of these concerns appeared to be based upon a good understanding of the limitations of mediation practices, but it is also apparent that some concerns were influenced by a misunderstanding and limited knowledge of contemporary mediation practice. It is recommended that family mediation services work proactively with women’s services in order to better inform each other of the possibilities and constraints in working with postseparation disputes.

Panel discussion: U.S. EPA using modeling and ecosystem services to enhance coastal decision making

This panel will discuss the research being conducted, and the models being used in three current coastal EPA studies being conducted on ecosystem services in Tampa Bay, the Chesapeake Bay and the Coastal Carolinas. These studies are intended to provide a broader and more comprehensive approach to policy and decision-making affecting coastal ecosystems as well as provide an account of valued services that have heretofore been largely unrecognized. Interim research products, including updated and integrated spatial data, models and model frameworks, and interactive decision support systems will be demonstrated to engage potential users and to elicit feedback. It is anticipated that the near-term impact of the projects will be to increase the awareness by coastal communities and coastal managers of the implications of their actions and to foster partnerships for ecosystem services research and applications.

Coastal resource planning system: Integrating evaluation of ecological integrity and ecosystem services valuation

Efficient and effective coastal management decisions rely on knowledge of the impact of human activities on ecosystem integrity, vulnerable species, and valued ecosystem services���collectively, human impact on environmental quality (EQ). Ecosystem-based management (EBM) is an emerging approach to address the dynamics and complexities of coupled social-ecological systems. EBM “is intended to directly address the long-term sustainable delivery of ecosystem services and the resilience of marine ecosystems to perturbations” (Rosenberg and Sandifer, 2009). The lack of a tool that integrates human choices with the ecological connections between contributing watersheds and nearshore areas, and that incorporates valuation of ecosystem services, is a critical missing piece needed for effective and efficient coastal management. To address the need for an integrative tool for evaluation of human impacts on ecosystems and their services, Battelle developed the EcoVal™ Environmental Quality Evaluation System. The EcoVal system is an updated (2009) version of the EQ Evaluation System for Water Resources developed by Battelle for the U.S. Bureau of Reclamation (Dee et al., 1972). The Battelle EQ evaluation system has a thirty-year history of providing a standard approach to evaluate watershed EQ. This paper describes the conceptual approach and methodology of the updated EcoVal system and its potential application to coastal ecosystems. (PDF contains 4 pages)

System architecture and deployment scenarios for SESAME: Small cEllS coordinAtion for Multi-tenancy and Edge services

The surge of the Internet traffic with exabytes of data flowing over operators mobile networks has created the need to rethink the paradigms behind the design of the mobile network architecture. The inadequacy of the 4G UMTS Long term Evolution (LTE) and even of its advanced version LTE-A is evident, considering that the traffic will be extremely heterogeneous in the near future and ranging from 4K resolution TV to machine-type communications. To keep up with these changes, academia, industries and EU institutions have now engaged in the quest for new 5G technology. In this paper we present the innovative system design, concepts and visions developed by the 5G PPP H2020 project SESAME (Small cEllS coordinAtion for Multi-tenancy and Edge services). The innovation of SESAME is manifold: i) combine the key 5G small cells with cloud technology, ii) promote and develop the concept of Small Cellsas- a-Service (SCaaS), iii) bring computing and storage power at the mobile network edge through the development of nonx86 ARM technology enabled micro-servers, and iv) address a large number of scenarios and use cases applying mobile edge computing.
