Stakeholder bargaining behaviour : the social backbone of communication, negotiation and consensus as used for information system requirements elicitation
Consensus making in requirements negotiation : the communication perspective
When developing an Information System (IS), organizational goals of various stakeholders are commonly in direct conflict. Furthermore, individuals often rank their private objectives well over their management\u27s directions. Recognising and reconciling all these diverse goals, and reaching agreement among the stakeholders, are prerequisite to establishing project cooperation and collaboration. This paper focuses, in particular, on the negotiation and consensus making during requirements elicitation - the earliest stages of the IS development process. As requirements elicitation involves rich communication between project stakeholders, we therefore explore negotiation and consensus making from the communication perspective. The resulting model assists our understanding of the communication factors that influence the consensus process during requirements negotiation.<br /
Me, myself, and nature: living with dementia and connecting with the natural world – more than a breath of fresh air? A literature review
Objective: Depsite the growing awareness of the importance of engagement with the natural world for people living with dementia, little is known about the impact specifically for people living independently in their own home. This review identifies, analyses and synthesises existing research, incorporating first-person narrative accounts of the benefits and potential challenges experienced inforging meaningful connections with the natural world.Methods: Six databases were searched from February 2000 to February 2021. Relevant organisations and authors were contacted, and a hand search of included study reference lists was conducted. The findings of included studies were synthesised using a thematic analysis approach.Findings: Sixteen studies were included: 13 qualitative and three mixed methods. Eight themes and three sub-themes were identified, revealing how contact with the natural world held a significancefor people living with dementia, associated with a sense of pleasure, comfort, stimulation, freedom and meaning. Support and the use of adaptive strategies afforded opportunities for continued engagement with meaningful outdoor activities and the promotion of identity, independence, social interaction, enhanced wellbeing and quality of life for people living independently with dementia.Conclusion: Meaningful connections with the natural world offer far more than a ‘breath of freshair’. When support mechanisms are in place, engaging with the natural world can be a valuable arenafor enablement and continuity, providing a sense of connectedness to self, place and others
A Generative Model of Speech Production in Broca’s and Wernicke’s Areas
Speech production involves the generation of an auditory signal from the articulators and vocal tract. When the intended auditory signal does not match the produced sounds, subsequent articulatory commands can be adjusted to reduce the difference between the intended and produced sounds. This requires an internal model of the intended speech output that can be compared to the produced speech. The aim of this functional imaging study was to identify brain activation related to the internal model of speech production after activation related to vocalization, auditory feedback, and movement in the articulators had been controlled. There were four conditions: silent articulation of speech, non-speech mouth movements, finger tapping, and visual fixation. In the speech conditions, participants produced the mouth movements associated with the words “one” and “three.” We eliminated auditory feedback from the spoken output by instructing participants to articulate these words without producing any sound. The non-speech mouth movement conditions involved lip pursing and tongue protrusions to control for movement in the articulators. The main difference between our speech and non-speech mouth movement conditions is that prior experience producing speech sounds leads to the automatic and covert generation of auditory and phonological associations that may play a role in predicting auditory feedback. We found that, relative to non-speech mouth movements, silent speech activated Broca’s area in the left dorsal pars opercularis and Wernicke’s area in the left posterior superior temporal sulcus. We discuss these results in the context of a generative model of speech production and propose that Broca’s and Wernicke’s areas may be involved in predicting the speech output that follows articulation. These predictions could provide a mechanism by which rapid movement of the articulators is precisely matched to the intended speech outputs during future articulations
Quantifying the Cost of Passive Smoking on Child Health: Evidence from Children's Cotinine Samples
Ost voices : local practices of the transformation in Eastern Germany, 1989-1991
The sheer scale of the transformation in Eastern Germany was unprecedented. It encompassed unforeseen levels of political, social, economic and cultural change within the space of a few months. And yet, this unique period is understudied in remarkable ways. This thesis contributes to the existing literature on transformation and democratisation processes by providing a detailed study of local transformation practices in Erfurt and Eisenach from 1989 to 1991.
Concentrating on the communal level, it examines the interrelationship between protest, consumption, politics and economic restructuring, and how these changes are reflected in social practices. It highlights the agency of local actors by illustrating the pressure under which eastern Germans worked and the ways in which they dealt with both successes and losses. For introducing and developing democratic practices in times of social, political and economic instability is an incredible challenge. From the grassroots perspective, this thesis highlights previously underappreciated forms of input and proactivity, as well as the immense constraints faced by actors on the ground.
Running throughout the thesis, however, is also the story of citizens trying to find and use their voice; actively renegotiating roles and structures, determining new forms of communication and tone, defending their interests and values, creating meanings and making sense of the past. As well as relating to wider questions of recent German politics and history, this thesis demonstrates how times of political and social uncertainty can lead to practices of social and financial marginalisation that significantly redefine citizens’ political agency
Epidemiology and individual, household and geographical risk factors of podoconiosis in ethiopia: results from the first nationwide mapping
Although podoconiosis is one of the major causes of tropical lymphoedema and is endemic in Ethiopia its epidemiology and risk factors are poorly understood. Individual-level data for 129,959 individuals from 1,315 communities in 659 woreda (districts) were collected for a nationwide integrated survey of lymphatic filariasis and podoconiosis. Blood samples were tested for circulating Wuchereria bancrofti antigen using immunochromatographic card tests. A clinical algorithm was used to reach a diagnosis of podoconiosis by excluding other potential causes of lymphoedema of the lower limb. Bayesian multilevel models were used to identify individual and environmental risk factors. Overall, 8,110 of 129,959 (6.2%, 95% confidence interval [CI] 6.1-6.4%) surveyed individuals were identified with lymphoedema of the lower limb, of whom 5,253 (4.0%, 95% CI 3.9-4.1%) were confirmed to be podoconiosis cases. In multivariable analysis, being female, older, unmarried, washing the feet less frequently than daily, and being semiskilled or unemployed were significantly associated with increased risk of podoconiosis. Attending formal education and living in a house with a covered floor were associated with decreased risk of podoconiosis. Podoconiosis exhibits marked geographical variation across Ethiopia, with variation in risk associated with variation in rainfall, enhanced vegetation index, and altitude
Sumo Puff: Tidal Debris or Disturbed Ultra-Diffuse Galaxy?
We report the discovery of a diffuse stellar cloud with an angular extent
, which we term "Sumo Puff", in data from the Hyper
Suprime-Cam Subaru Strategic Program (HSC-SSP). While we do not have a redshift
for this object, it is in close angular proximity to a post-merger galaxy at
redshift and is projected within a few virial radii (assuming
similar redshifts) of two other galaxies, which we use to
bracket a potential redshift range of . The object's light
distribution is flat, as characterized by a low Sersic index (). It
has a low central -band surface brightness of mag
arcsec, large effective radius of (
kpc at and kpc at ), and an elongated
morphology (). Its red color () is consistent with a
passively evolving stellar population and similar to the nearby post-merger
galaxy, and we may see tidal material connecting Sumo Puff with this galaxy. We
offer two possible interpretations for the nature of this object: (1) it is an
extreme, galaxy-size tidal feature associated with a recent merger event, or
(2) it is a foreground dwarf galaxy with properties consistent with a quenched,
disturbed ultra-diffuse galaxy. We present a qualitative comparison with
simulations that demonstrates the feasibility of forming a structure similar to
this object in a merger event. Follow-up spectroscopy and/or deeper imaging to
confirm the presence of the bridge of tidal material will be necessary to
reveal the true nature of this object.Comment: 10 pages, 5 figures, submitted to PASJ for the HSC-SSP special issu
