Transactional Analysis as a personality theory has offered some powerful concepts to explain and improve communication between individuals. On the other hand, positive productive communication among large numbers of people, as a compound set of transactions, as an essential aspect of human survival has not been so well explained. Like the weather and other chaotic processes, group behavior is not easily understood or predicted. It has been long suspected that in large groups of people (organizations, communities, societies), positive communication has a leading role in maintaining the duration and quality of communication. It is the aim of this paper to relate the mathematics notion of dynamical systems to the compound system of communication. The postulate that strokes, a concept introduced by E. Berne as a way in which people recognize each other, and elaborated by Steiner as a way of exchanging information, is discussed as a concept that introduces stability into the functioning of large groups.

ABSTRACT Online labor markets allow rapid recruitment of large numbers of workers for very low pay. Although online workers are often used as research participants, there is little evidence that they are motivated to make costly choices to forgo wealth or leisure that are often central to addressing accounting research questions. Thus, we investigate the validity of using online workers as a proxy for non-experts when accounting research designs use more demanding tasks than these workers typically complete. Three experiments examine the costly choices of online workers relative to student research participants. We find that online workers are at least as willing as students to make costly choices, even at significantly lower wages. We also find that online workers are sensitive to performance-based wages, which are just as effective in inducing high effort as high fixed wages. We discuss implications of our results for conducting accounting research with online workers. Data Availability: Contact the authors.

Summary Objectives: The Yearbook of Medical Informatics is published annually by the International Medical Informatics Association (IMIA) and contains a selection of excellent papers on medical informatics research which have been recently published (www.yearbook.uni-hd.de). The 2003 Yearbook of Medical Informatics took as its theme the role of medical informatics for the quality of health care. In this paper, we will discuss challenges for health care, and the lessons learned from editing IMIA Yearbook 2003. Results and Conclusions: Modern information processing methodology and information and communication technology have strongly influenced our societies and health care. As a consequence of this, medical informatics as a discipline has taken a leading role in the further development of health care. This involves developing information systems that enhance opportunities for global access to health services and medical knowledge. Informatics methodology and technology will facilitate high quality of care in aging societies, and will decrease the possibilities of health care errors. It will also enable the dissemination of the latest medical and health information on the web to consumers and health care providers alike. The selected papers of the IMIA Yearbook 2003 present clear examples and future challenges, and they highlight how various sub-disciplines of medical informatics can contribute to this.

Vitro Test

In the quality control of vaccine batches, the potency testing of inactivated vaccines is one of the areas requiring very large numbers of animals, which usually suffer significant distress as a result of the experimental procedures employed. This article deals with the potency testing of diphtheria and tetanus toxoids, two vaccines which are used extensively throughout the world. The relevance of the potency test prescribed by the European Pharmacopoeia monographs is questioned. The validity of the potency test as a model for the human response, the ability of the test to be standardised, and the relevance of the test in relation to the quality of the product are discussed. It is concluded that the potency test has only limited predictive value for the antitoxin responses to be expected in recipients of these toxoids. An alternative approach for estimating the potency of toxoid batches is discussed, in which a distinction is made between estimation of the immunogenic potency of the first few batches obtained from a seed lot and monitoring the consistency of the quality of subsequent batches. The use of animals is limited to the first few batches. Monitoring the consistency of the quality of subsequent batches is based on in vitro test methods. Factors which hamper the introduction and acceptance of the alternative approach are considered. Finally, proposals are made for replacement, reduction and/or refinement (the Three Rs) in the use of animals in the routine potency testing of toxoids.

This paper reports on work carried out in the School of Management at Heriot-Watt University in Edinburgh. Following a wide-ranging review of the first-year management programme, a module on enterprise was introduced. As part of that module students had to compete in a game, the object of which was to come up with a business idea, conduct market research and present a business plan and proposal to a panel of judges. The number of students was 225 in year one but reached around 500 within five years. The module has generated many good ideas and has attracted sponsorship from commercial sources. As yet the university has been unable to take the ideas further. It is possible that enterprise can be learned by people in large numbers, but perhaps universities are not the places in which to attempt such work.

In the fall of 2014 the Quebec Health Ministry announced plans for a broad restructuring of the entire Healthcare network, implemented shortly thereafter in 2015. The effect on institutions was dramatic and immediate. Local  management was eradicated, concentrating and centralizing control of the entire system ultimately into the office of the Minister. With the abrupt reorganization of services came relocation of large numbers of personnel. Management at a distance became the norm. In many institutions, the commonly held view among physicians with regard to relations with management can be summarized as, “Suddenly there was no one to talk to.”Confusion and tension were prevalent and palpable. In this context, in attempt to have a voice, a group of physicians at one community hospital formed an independent organization. It developed into an influential body which continues to remain active. This workshop will use the experiences and reflections of physicians from that organization as a basis to explore questions such as: -Is there a difference between Health Services and Health Care? Do we care? -Does worker engagement matter in Healthcare delivery? Or are good systems and modern equipment all we really need? -Does sense of community matter within a healthcare institution? If so why?If it matters, is it just for the benefit of those working for the organization? Or is there a benefit for the users too? -What is the basis for sense of community? Where does it come from? Can it be destroyed? Can it be developed? -Is there an importance to the quality of relationships between people working within Healthcare? Do these relationships have impact on quality of care? -Should the perspective of those working in the system be incorporated input Management decision making? If so how? -What can physicians, nurses and other allied Healthcare professionals do in order to have a voice?

The illocutionary complex that determines the pragmatic meaning of text units with purpose semantics as part of the question-answer dialogue was analyzed. Using the methods of conversation analysis, introspection, linguistic modeling and observation, a multifarious analysis of the adjacent pairs in the political interview and talk show fragments was carried out. The factors that define the generation of purpose-related judgments and the choice of indirect ways to convey the communicative intentions of the addresser were singled out, as well as the aspects that are important for understanding the perceived content by the addressee. The organization of the communicative continuum within the framework of interaction was investigated. The functionality of the pragmatic context (the background of spoken interaction) was revealed. The factors influencing the quality of the illocutionary profile of text units (clarity/blur) as it is perceived and interpreted by the addressee were established. The signals of the communicative intentions generated by the addresser were considered. The choice of spoken response in the situations of harsh pressure was discussed. It was demonstrated that the pragmatic context plays a leading role in perceiving of the illocutionary complex during the communicative interaction.

Abstract Objective. Microelectrode arrays are standard tools for conducting chronic electrophysiological experiments, allowing researchers to simultaneously record from large numbers of neurons. Specifically, Utah electrode arrays (UEAs) have been utilized by scientists in many species, including rodents, rhesus macaques, marmosets, and human participants. The field of clinical human brain-computer interfaces currently relies on the UEA as a number of research groups have FDA clearance for this device through the investigational device exemption pathway. Despite its widespread usage in systems neuroscience, few studies have comprehensively evaluated the reliability and signal quality of the Utah array over long periods of time in a large dataset. Approach. We collected and analyzed over 6000 recorded datasets from various cortical areas spanning almost 9 years of experiments, totaling 17 rhesus macaques (Macaca Mulatta) and 2 human subjects, and 55 separate microelectrode Utah arrays. The scale of this dataset allowed us to evaluate the average life of these arrays, based primarily on the signal-to-noise ratio of each electrode over time. Main Results. Using implants in primary motor, premotor, prefrontal, and somatosensory cortices, we found that the average lifespan of available recordings from UEAs was 622 days, although we provide several examples of these UEAs lasting over 1000 days and one up to 9 years; human implants were also shown to last longer than non-human primate implants. We also found that electrode length did not affect longevity and quality, but iridium oxide metallization on the electrode tip exhibited superior yield as compared to platinum metallization.
