Life Beyond the Mailbox: A Cross-Tool Perspective on Personal Information Management
Email interfaces provide poor support for the personal
information management (PIM) activities that users have
adopted them for. This paper reports a user study that
highlights how two aspects of PIM, information
management and task management, cut across a range of
tools, including email. We argue that effective support for
such cross-tool activities cannot be provided through a
focus on one interface such as email alone. Instead, a cross-tool approach is needed in PIM-related research and design. We present a prototype aimed at improving cross-tool support for information management, and report the results from an initial evaluation

Help-seeking in emerging adults with and without a history of mental health referral: a qualitative study.
BACKGROUND: Young people are generally reluctant to seek professional help when experiencing problems. However, past experience of services is often cited as increasing the intention to seek help, therefore those with a history of mental health referral may adopt more adaptive help seeking strategies. The current study investigated whether the pattern of different help seeking strategies and barriers to help seeking differed as a function of previous referral history. METHODS: Semi-structured interviews were conducted with 29 emerging adults (12 males, 17 females); 17 with a history of mental health referral and 12 without and analysed using thematic analysis. RESULTS: Overall, those with a referral to services were more likely than those without to rely on avoidant coping, especially techniques that depended upon suppression. This could help account for the increased use of strategies involving self-harm and substances in those with past referral. An exploration of barriers to help seeking showed those with a history of mental health referral were much more likely to self-stigmatise and this became attached to their sense of identity. CONCLUSIONS: Emerging adults with a history of referral are more likely to adopt avoidant coping strategies when dealing with problems and self-stigmatise to a greater degree than those without a history of referral. This suggests that current approaches to mental health in emerging adults are not decreasing the sense of stigma with potentially far-reaching consequences for the developing sense of self and choice of help seeking strategies
Application of intersatellite links to domestic satellite systems
The results of a study on intersatellite link (ISL) applications for domestic satellite communications are presented. It was determined if any technical, economic, or performance benefits could be gained by introducing intersatellite links into a domestic satellite communication network. Several key systems issues of domestic ISL's are addressed. These include the effect of a skewed traffic distribution on the selection of ISL satellite orbit locations, tolerable satellite spacing, and crosslink traffic-handling requirements. An ISL technology assessment is made by performing a parametric link analysis for several microwave and optical implementations. The impact of the crosslink on the end-to-end link performance is investigated for both regenerative and nonregenerative ISL architectures. A comparison is made between single satellite systems operating at C-, and Ku-bands and the corresponding ISL systems in terms of ground segment cost, space segment cost, and net link performance. Results indicate that ISL's can effectively expand the CONUS orbital arc, with a 60 GHz ISL implementation being the most attractive
Analysis of a Helmholtz preconditioning problem motivated by uncertainty quantification
This paper analyses the following question: let , be
the Galerkin matrices corresponding to finite-element discretisations of the
exterior Dirichlet problem for the heterogeneous Helmholtz equations
. How small must and be (in terms of -dependence) for
GMRES applied to either or
to converge in a -independent number of
iterations for arbitrarily large ? (In other words, for to be
a good left- or right-preconditioner for ?). We prove results
answering this question, give theoretical evidence for their sharpness, and
give numerical experiments supporting the estimates.
Our motivation for tackling this question comes from calculating quantities
of interest for the Helmholtz equation with random coefficients and .
Such a calculation may require the solution of many deterministic Helmholtz
problems, each with different and , and the answer to the question above
dictates to what extent a previously-calculated inverse of one of the Galerkin
matrices can be used as a preconditioner for other Galerkin matrices
Primary connections in a provincial Queensland school system: relationships to science teaching self-efficacy and practices
The teaching of science is important, both to meet the need for future workers in fields requiring scientific capability and to equip students for full participation in modern societies where many decisions depend upon knowledge of science. However, many teachers in Australian primary schools do not allocate science education sufficient amounts of time to achieve these outcomes. This study reports data obtained from 216 teachers in the primary schools in a provincial Australian school system. The purpose of the study was to assess the effects of existing strategies using Primary Connections for promoting science teaching and to inform future professional development strategies. Teachers reported moderate levels of self-efficacy for teaching science and a proportion reported allocating little or no time to teaching science. Both self-efficacy for science teaching and the amount of science taught were higher for teachers who had used Primary Connections curriculum materials
On The Reporting Of Reliability In Content Analysis
This article explores one type of misreporting of reliability that has been seen in recent conference papers and articles using the method of content analysis. The reporting of reliability is central to the validity of claims made using this method. A brief overview of content analysis is offered, followed by the exploration of one type of misreporting of reliability. Suggestions are offered to address the problem
Social Capital: A review from an ethics perspective
In this paper we extend previous reviews of the social capital literature to encompass an ethics perspective. First, we update previous reviews of social capital. Social capital continues to gain currency in both academic and practical circles, despite relatively little critical reflection on the implications of promoting this popular concept. Our work goes some way to rectifying this paucity in understanding what has been termed the ‘dark side’ of social capital. In particular, we review the social capital concept from the perspective of three theories of business ethics: utilitarianism, justice and ethic of care. While the utilitarian perspective closely parallels accounts of social capital’s rationale, the concept’s operation is mirrored very closely by the assumptions underpinning the ethic of care, while the dark side of social capital is commonly given voice in justice-based critiques. We conclude by considering the implications of our analysis
