The impact of rhetoric and reality on community anticipation of risk in the development of multi-purpose services (MPS) : A grounded theory study

better health service.Conclusion:This research provides an insight into the perceptions of the rhetoric and reality of community member involvement in the process of developing multi-purpose services. It revealed a grounded theory in which fear and trust were intrinsic to a process of changing from a traditional hospital service to the acceptance of a new model of health care provided at a multi-purpose service.

Nanostructuring of p- and n-type skutterudites reaching figures of merit of approximately 1.3 and 1.6, respectively

Thermoelectric (TE) conversion of waste heat into useful electricity demands optimized thermal and electrical transport in the leg material over a wide temperature range. In order to gain a reasonably high figure of merit (ZT) as well as high thermal electric conversion efficiency, various conditions of the starting material were studied: industrially produced skutterudite powders of p-type DDy(Fe1-xCox)(4)Sb-12 (DD: didymium) and n-type (Mm, Sm)(y)Co4Sb12 (Mm: mischmetal) were used. After a rather fast reaction-melting technique, the bulk was crushed and sieved with various strainers in order to obtain particles below the respective mesh sizes, followed by ball-milling under three different conditions. The dependence of the TE properties (after hot pressing) on the micro/nanosized particles, grains and crystallites was investigated. Optimized conditions resulted in an increase of ZT for bulk material to current record-high values: from ZT similar to 1.1 to ZT similar to 1.3 at 775 K for p-type and from ZT similar to 1.0 to ZT similar to 1.6 at 800 K for n-type, resulting in respective efficiencies (300-850 K) of eta > 13% and eta similar to 16%.

Exploring figures of merit associated with the suboptimum operation of class-E power amplifiers

Closed-form design equations for the operation of a class-E amplifier for zero switch voltage slope and arbitrary duty cycle are derived. This approach allows an additional degree of freedom in the design of class-E amplifiers which are normally designed for 50 duty ratio. The analysis developed permits the selection of non-unique solutions where amplifier efficiency is theoretically 100 but power output capability is less than that the 50 duty ratio case would permit. To facilitate comparison between 50 (optimal) and non-50 (suboptimal) duty ratio cases, each important amplifier parameter is normalised to its corresponding optimum operation value. It is shown that by choosing a non-50 suboptimal solution, the operating frequency of a class-E amplifier can be extended. In addition, it is shown that by operating the amplifier in the suboptimal regime, other amplifier parameters, for example, transistor output capacitance or peak switch voltage, can be included along with the standard specification criteria of output power, DC supply voltage and operating frequency as additional input design specifications. Suboptimum class-E operation may have potential advantages for monolithic microwave integrated circuit realisation as lower inductance values (lower series resistance, higher self-resonance frequency, less area) may be required when compared with the results obtained for optimal class-E amplifier synthesis. The theoretical analysis conducted here was verified by harmonic balance simulation, with excellent agreement between both methods. © The Institution of Engineering and Technology 2007.

Working in teams : the influence of rhetoric-from sensemaking to sadness

At a time when teams are increasingly and routinely being used in Public Administration (PA) organizations, the prevailing wisdom about teams continues to confirm that teams axiomatically bring increases and improvements in effectiveness, productivity and communication. There has been relatively little critical address of whether these benefits actually accrue, nor what the experience of team members actually is. The PA literature, in particular, remains silent on this important issue. This paper shares findings from an exploratory phenomenological study. Members of teams in organizations were interviewed and asked about their experiences of working in teams. In contrast to the current wisdom, not only did team members not report the anticipated improvements and benefits, their stories tended to highlight the negative influence that the rhetoric surrounding teams might have on individuals. This paper shares the responses of team members to that rhetoric, revealing themes of "Teams, Rhetoric and Sensemaking," a challenge to the notion of "Teams as One Big Happy Family?" while identifying "Teams as Crucibles of Resignation and Sadness." These findings indicate the continuing need for further research into understanding the experience of individuals within various team and organizational structures, especially as they operate in PA organizations.

Working in teams: the influence of rhetoric-from sensemaking to sadness

The prevailing wisdom tells us that teams axiomatically bring increases and improvements in effectiveness, productivity and communication. There has been too little critical address of whether these benefits actually accrue, nor what the experience of team members actually is. This paper shares findings from a Heideggerian phenomenological study, where members of teams in organizations were interviewed and asked about their experiences of working in teams. Astonishingly, not only did team members not report these anticipated improvements, their stories tended to highlight the negative influence that the rhetoric surrounding teams might have on individuals. This paper shares the responses of team members to that rhetoric, revealing themes of "Teams, Rhetoric and Sensemaking", a challenge to the notion of "Teams as One Big Happy Family?", and "Teams as Crucibles of Resignation and Sadness". These findings indicate the need for future research into understanding the experience of individuals within various team and organizational structures.

Figures of equilibrium for tidally deformed non-homogeneous celestial bodies

Abstract (2,250 Maximum Characters): Several theories of tidal evolution, since the theory developed by Darwin in the XIX century, are based on the figure of equilibrium of the tidally deformed body. Frequently the adopted figure is a Jeans prolate spheroid. In some case, however, the rotation is important and Roche ellipsoids are used. The main limitations of these models are (a) they refer to homogeneous bodies; (b) the rotation axis is perpendicular to the plane of the orbit. This communication aims at presenting several results in which these hypotheses are not done. In what concerns the non-homogeneity, the presented results concerns initially bodies formed by N homogeneous layers and we study the non sphericity of each layer and relate them to the density distribution. The result is similar to the Clairaut figure of equilibrium, often used in planetary sciences, but taking into full account the tidal deformation. The case of the rotation axis non perpendicular to the orbital plane is much more complex and the study has been restricted for the moment to the case of homogeneous bodies.

Add a Dash of Rhetoric, a Pinch of Technical Communication, a Handful of Pedagogy, and Mix Well: Cookbooks and Recipes as Instructional Texts, and What Domestic Texts from 1870 to 1935 Can Teach Us About Technical Communication

Through the use of rhetoric centered on authority and risk avoidance, scientific method has co-opted knowledge, especially women's everyday and experiential knowledge in the domestic sphere. This, in turn, has produced a profound affect on technical communication in the present day. I am drawing on rhetorical theory to study cookbooks and recipes for their contributions to changes in instructional texts. Using the rhetorical lenses of metis (cunning intelligence), kairos (timing and fitness) and mneme (memory), I examine the way in which recipes and cookbooks are constructed, used and perceived. This helps me uncover lost voices in history, the voices of women who used recipes, produced cookbooks and changed the way instructions read. Beginning with the earliest cookbooks and recipes, but focusing on the pivotal temporal interval of 1870-1935, I investigate the writing and rhetorical forces shaping instruction sets and domestic discourse. By the time of scientific cooking and domestic science, everyday and experiential knowledge were being excluded to make room for scientific method and the industrial values of the public sphere. In this study, I also assess how the public sphere, via Cooperative Extension Services and other government agencies, impacted the domestic sphere, further devaluing everyday knowledge in favor of the public scientific model. I will show how the changes in the production of food, cookbooks and recipes were related to changes in technical communication. These changes had wide rippling effects on the field of technical communication. By returning to some of the tenets and traditions of everyday and experiential knowledge, technical communication scholars, practitioners and instructors today can find new ways to encounter technical communication, specifically regarding the creation of instructional texts. Bringing cookbooks, recipes and everyday knowledge into the classroom and the field engenders a new realm of epistemological possibilities.
