Order of question presentation and correlation between judgments of comparative and own risk

Unrealistic optimism is often assessed using a single question asking for an estimate of comparative risk. However, it has been proposed that individuals treat such a question essentially as though it were only about their own risk. This proposal leads to the prediction that, when the questions about own risk and comparative risk are asked in sequence, the correlation between the resulting estimates should be lower if the question about own risk comes first than if the question about comparative risk comes first. This prediction was tested using a student sample (N=68). Participants answered the two types of question in sequence, with order of presentation being counterbalanced. Results were in accord with the prediction. Possible reasons are advanced for individuals' answering questions about comparative risk as if the questions concerned their own risk.

Triangulation in organizational research : a re-presentation

This paper extends the discussion of postmodern thinking in organizational theory through a re-presentation of the concept of triangulation in organizational research. Initially triangulation is defined through the contrasting lenses of positivism and post-positivism/postmodernism and analysed as a metaphor for fixing and capturing the research subject. Subsequently triangulation is ‘re-presented’ as ‘metaphorization’—in terms of process and movement between researcher-subject positions. Rethinking the lines and angles of enquiry in triangulation, the paper suggests a shift from the ‘triangulation of distance’ tradition to a more reflexive consideration of ‘researcher stance’. This movement is represented across three perspectives: the researcher as a follower of nomothetic lines; the researcher as the taker of an ideographic overview; and the researcher as the finder of a particular angle. The implications of this re-presentation are then discussed in terms of perspective, data capture, reflexivity and metatriangulation.

The roles of prior experience and the timing of misinformation presentation on young children's event memories

The current study addressed how the timing of interviews affected children's memories of unique and repeated events. Five- to six-year-olds (N= 125) participated in activities 1 or 4 times and were misinformed either 3 or 21 days after the only or last event. Although single-experience children were subsequently less accurate in the 21- versus 3-day condition, the timing of the misinformation session did not affect memories of repeated-experience children regarding invariant details. Children were more suggestible in the 21- versus 3-day condition for variable details when the test occurred soon after misinformation presentation. Thus, timing differentially affected memories of single and repeated events and depended on the combination of event-misinformation and misinformation-test delays rather than the overall retention interval.

Is tendon pathology a continuum? A pathology model to explain the clinical presentation of load-induced tendinopathy

Overuse tendinopathy is problematic to manage clinically. People of different ages with tendons under diverse loads present with varying degrees of pain, irritability, and capacity to function. Recovery is similarly variable; some tendons recover with simple interventions, some remain resistant to all treatments.

The pathology of tendinopathy has been described as degenerative or failed healing. Neither of these descriptions fully explains the heterogeneity of presentation. This review proposes, and provides evidence for, a continuum of pathology. This model of pathology allows rational placement of treatments along the continuum.

A new model of tendinopathy and thoughtful treatment implementation may improve outcomes for those with tendinopathy. This model is presented for evaluation by clinicians and researchers.

Simultaneous presentation of measured and calculated environmental results

Continuous measurement of internal and external environmental parameters is critical to our understanding of how buildings perform. Yet, the quantity and variety of time-series data can be quite overwhelming as well as onerous to decipher and present. In addition to this, is the fact that several of the collected data are useless in their raw format unless processed through algorithms to obtain identifiable and meaningful results.
These circumstances challenge the conventional way we present accumulated data and their processed outputs in order to get a better understanding of how and why the environmental performance occurred. It would be ideal if all of the collected and processed data could be presented in a simultaneous, yet, useful format. It is exactly the intention of this paper to suggest and present such a process as well as its format.
An example case study is provided where several parameters (air velocity, mean radiant temperature, humidity and air temperature) are measured periodically to calculate a time-series of internal comfort performance. However, external conditions of solar radiation and solar position as well as air temperature drive the interior building surface temperatures and help to explain the end result of internal comfort.
A program has been written to present the various sets of data graphically, in an integrated manner, animated as a function of time. The animation shows solar position, a cursor scanning weather data, the changing infra-red image and a representation of the resulting internal comfort performance throughout the
monitored period.

Children's eyewitness memory : participation, presentation media and the disruption effect

This research found that both younger and older children remembered eyewitness events better when presented live rather than on video. Active participation in live events enhanced recall memory. Disruptive incidents were remembered better than irrelevant incidents, but this finding depended on children's age and level of involvement in the event.

The presentation of gendered selves in everyday friendship

This thesis explores the gender differences in the way men and women conduct themselves in everyday friendship interaction, finding that the informal rules governing friendship interaction allow individuals a level of freedom to enact gender to extremes in the company of friends. Generational changes in men's friendships are also noted.

Systemic activation of dendritic cells by toll-like receptor ligands or malaria infection impairs cross-presentation and antiviral immunity

The mechanisms responsible for the immunosuppression associated with sepsis or some chronic blood infections remain poorly understood. Here we show that infection with a malaria parasite (Plasmodium berghei) or simple systemic exposure to bacterial or viral Toll-like receptor ligands inhibited cross-priming. Reduced cross-priming was a consequence of downregulation of cross-presentation by activated dendritic cells due to systemic activation that did not otherwise globally inhibit T cell proliferation. Although activated dendritic cells retained their capacity to present viral antigens via the endogenous major histocompatibility complex class I processing pathway, antiviral responses were greatly impaired in mice exposed to Toll-like receptor ligands. This is consistent with a key function for cross-presentation in antiviral immunity and helps explain the immunosuppressive effects of systemic infection. Moreover, inhibition of cross-presentation was overcome by injection of dendritic cells bearing antigen, which provides a new strategy for generating immunity during immunosuppressive blood infections.
