To develop and test a standardised clinical handover discharge strategy for improving information transfer between private mental health hospitals and community practitioners. A quality improvement intervention using collaborative, iterative methods to develop a standardised discharge and outcome assessment strategy. 150 patient participants were consecutively recruited from two private mental health care hospitals in New South Wales between April and September 2008. Opinions of community practitioners and patients on the discharge process and discharge documentation were solicited by written questionnaires and telephone interviews. Community practitioner satisfaction; patient satisfaction; documentation of discharge date at least 48 hours before discharge; faxing of discharge summaries to community practitioners within 48 hours of discharge; proportion of patients receiving a follow-up telephone call within 7 days or 14 days of discharge. Both community practitioners and patients b...

Secure information distribution is a strategic capability as significant as weapons systems and tactics to military operations. The Department of Defense has recognized the importance of establishing and maintaining secure distributed file systems and explores the practicality and applicability of one such system, Trusted Ficus File System (TRUFFLES), in the DoD infrastructure. Integrated into this research are discussions of Privacy Enhanced Mail (PEM), which is currently an integral part of the TRUFFLES implementation. This thesis concludes with a discussion of the actual installation of a PEM reference implementation, and future requirements for the TRUFFLES installation at the Naval Postgraduate School.

Historically, engineers at the National Aeronautics and Space Administration (NASA) had few opportunities or incentives to share their technical expertise across the Agency. Its centerand projectfocused culture often meant that knowledge never left organizational and geographic boundaries. With increasingly complex missions, the closeout of the Shuttle Program, and a new generation entering the workforce, developing a knowledge sharing culture became critical. To address this need, the Office of the Chief Engineer established communities of practice on the NASA Engineering Network. These communities were strategically aligned with NASA’s core competencies in such disciplines as avionics, flight mechanics, life support, propulsion, structures, loads and dynamics, human factors, and guidance, navigation, and control. This paper describes the process used to identify and develop communities, from establishing simple websites that compiled discipline-specific resources to fostering a kn...

The sense of touch is an effective, but underutilized, human communication channel. In this paper we describe our research efforts towards optimizing a minimal tactile array for personal navigation and route guidance. There are several aspects to this problem. From an information transfer viewpoint, the question of tactor array size, dimension, location and display symbology requires careful consideration. Effective tactile display symbology involves providing information in an intuitive manner without adding to the cognitive loading of the user. Tactile information may be presented through spatial, temporal and signal variables. We have recently developed new wearable tactors that offer wide sensory capabilities to provide different “feeling” stimuli. These actuators are non-linear in that the salient characteristics for perception are linked to a complex drive stimulus. We have therefore developed a tactor activation design approach termed “TActions” (Tactile Actions) where patterns or sequence of individual tactile stimuli, each of which has its own characteristics and properties, are used to create tactile display symbology that a user can naturally associate with a particular function. These components provide display design frame work which we have used to demonstrate orientation and navigation.

The challenge in maintaining patient autonomy regarding medical decision-making and confidentiality lies not only in control over information transferred to and regarding patients, but in the ambiguity of autonomy itself. Post-modernity is characterized by the recognition of not just numerous accounts of autonomy, but by the inability in a principled fashion to select one as canonical. Autonomy is understood as a good, a right-making condition, and an element of human flourishing. In each case, it can have a different content, depending in part on whether it is given a nomological or a volitional construal. Different accounts of autonomy can lead to strikingly different understandings of appropriate behavior, including the argument that one ought on behalf of autonomy to liberate individuals from the sense of autonomy they themselves affirm. In the face of competing accounts of moral probity, autonomy in a secular morality and bioethics must by default be understood in terms of the ...

Most Brain–Computer Interface (BCI) research aims at helping people who are severely paralyzed to regain control over their environment and to communicate with their social environment. There has been a tremendous increase in BCI research the last years, which might lead to the belief that we are close to a commercially available BCI applications to patients. However, studies with users from the future target group (those who are indeed paralyzed) are still outnumbered by studies on technical aspects of BCI applications and studies with healthy young participants. This might explain why the number of patients who use a BCI in daily life, without experts from a BCI group being present, can be counted on one hand.

Interaction with machines is mediated by human–machine interfaces (HMIs). Brain–machine interfaces (BMIs) are a particular class of HMIs and have so far been studied as a communication means for people who have little or no voluntary control of muscle activity. In this context, low-performing interfaces can be considered as prosthetic applications. On the other hand, for able-bodied users, a BMI would only be practical if conceived as an augmenting interface. In this paper, a method is introduced for pointing out effective ...

The existence of psi—anomalous processes of information transfer such as telepathy or clair- voyance—continues to be controversial. Earlier meta-analyses of studies using the ganzfeld procedure appeared to provide replicable evidence for psi (D. J. Bem & C. Honorton, 1994), but a follow-up meta-analysis of 30 more recent ganzfeld studies did not (J. Milton & R. Wiseman, 1999). When 10 new

This paper discusses a passage from the finale of Heliodorus' Aethiopica which has hitherto been interpreted as suggesting that Charicles, the heroine's foster-father, possesses information which he should not hold according to earlier parts of the novel. Offering two solutions to the Charicles puzzle, this article sheds light on important narratological characteristics of Heliodorus' novel: firstly, the Aethiopica opens itself to a 'completive mode of reading', which prompts the reader to speculate about unnarrated parts of the story; secondly, profound ambiguities can trigger chain reactions of alternative readings which reach far into parts of the plot that are connected with the ambiguous segment.

The need for electronic signatures in management processes is becoming more important as value chain and supplier flows become fully electronic. Many operations and process managers have introduced electronic tools for sign-off within process flows. However, few realize the legal implications or validity of international processes that use electronic signatures. Fully electronic information flows facilitate global commerce, but when working

As haptics becomes an integral component of scientific data visualization systems, there is a growing need to study "haptic glyphs" (building blocks for displaying information through the sense of touch) and quantify their information transmission capability. The present study investigated the channel capacity for transmitting information through stiffness or force magnitude. Specifically, we measured the number of stiffness or force- magnitude levels that can be reliably identified in an absolute identification paradigm. The range of stiffness and force magnitude used in the present study, 0.2-3.0 N/mm and 0.1-5.0 N, respectively, was typical of the parameter values encountered in most virtual reality or data visualization applications. Ten individuals participated in a stiffness identification experiment, each completing 250 trials. Subsequently, four of these individuals and six additional participants completed 250 trials in a force-magnitude identification experiment. A custom-designed 3 degrees-of-freedom force-feedback device, the ministick, was used for stimulus delivery. The results showed an average information transfer of 1.46 bits for stiffness identification, or equivalently, 2.8 correctly-identifiable stiffness levels. The average information transfer for force magnitude was 1.54 bits, or equivalently, 2.9 correctly-identifiable force magnitudes. Therefore, on average, the participants could only reliably identify 2-3 stiffness levels in the range of 0.2-3.0 N/mm, and 2-3 force- magnitude levels in the range of 0.1-5.0 N. Individual performance varied from 1 to 4 correctly-identifiable stiffness levels and 2 to 4 correctly-identifiable force-magnitude levels. Our results are consistent with reported information transfers for haptic stimuli. Based on the present study, it is recommended that 2 stiffness or force-magnitude levels (i.e., high and low) be used with haptic glyphs in a data visualization system, with an additional third level (medium) for more experienced users.
