All good things come in threes: the third image of the lensed quasar PKS1830-211
2020
Strong gravitational lensing distorts our view of sources at cosmological distances but brings invaluable constraints on the mass content of foreground objects and on the geometry and properties of the Universe. We report the detection of a third continuum source toward the strongly lensed quasar PKS1830-211 in ALMA multi-frequency observations of high dynamic range and high angular resolution. This third source is point-like and located slightly to the north of the diagonal joining the two main lensed images, A and B, 0.3 arcsec away from image B. It has a flux density that is ~140 times weaker than images A and B and a similar spectral index, compatible with synchrotron emission. We concl…
Phonons in an inhomogeneous continuum: Vibrations of an embedded nanoparticle
2004
The spectrum of acoustic vibrational modes of an inhomogeneous elastic continuum are analyzed with application to a spherical nanoparticle embedded in an infinite glass block. The relationship of these modes to the discrete vibrational spectrum of a free sphere is studied. The vibrational modes of a sphere with a fixed surface are relevant in some situations. Comparisons are also made to calculations of mode frequency and damping based on complex valued frequency.
XMM-Newton First-Light Observations of the Hickson Galaxy Group 16
2000
This paper presents the XMM-Newton first-light observations of the Hickson-16 compact group of galaxies. Groups are possibly the oldest large-scale structures in the Universe, pre-dating clusters of galaxies, and are highly evolved. This group of small galaxies, at a redshift of 0.0132 (or 80 Mpc) is exceptional in the having the highest concentration of starburst or AGN activity in the nearby Universe. So it is a veritable laboratory for the study of the relationship between galaxy interactions and nuclear activity. Previous optical emission line studies indicated a strong ionising continuum in the galaxies, but its origin, whether from starbursts, or AGN, was unclear. Combined imaging and…
Theoretical study of the discrete and continuum spectrum of BeH
2008
The transition intensities supplied in this Letter are directly connected with a description of the discrete and continuum spectrum of BeH. An attempt to meet our goal requires the calculation of the absorption oscillator strengths of several transitions to Rydberg states of BeH, together with differential oscillator strengths which give rise to different dipole-allowed photoionization channels from the molecular ground state. The calculations have been performed with the molecular-adapted quantum defect orbital (MQDO) approach. Predictions of new spectroscopic data on BeH at energies where high Rydberg transitions can take place, including the continuum region of the spectrum have been mad…
Évaluation, concertation, et processus de décision
2003
The author outlines the theoretical and sociological considerations influencing the decision-making cycle for the French education ministry. He makes the case that education policy has been guided by ideological and political considerations rather than by scientific evidence and evaluation-based processes. He calls for widespread use of external appraisals involving the concerned actors.
Applying systematic review search methods to the grey literature: a review of education and training courses on breastfeeding support for health prof…
2021
Abstract Background Currently, lactation training courses aimed at health professionals are important for informing and supporting mothers who are breastfeeding. In this review, we seek to analyze similarities and/or variations in course content, modes of delivery, costs, teaching style and learning strategies among courses. To our knowledge, a review of lactation training courses available worldwide is lacking. Thus, the aim of this review is to describe course models aimed at training health professionals in lactation support for mothers. Methods Through searching grey literature, training courses were obtained from several directories, including the Alaska Breastfeeding Coalition, Intern…
Sensitivity in topic development and meaning making in a process consultation contract meeting
2013
PurposeThe purpose of this paper is to explore the discursive practices used when the agenda for a consultation process was negotiated in a contract meeting. The paper illustrates the role of sensitivity in meaning making practices, that is, how displays of sensitivity were intertwined with topic development.Design/methodology/approachThe paper offers an in‐depth analysis of naturally occurring conversation in a meeting between a consultant and two client managers. The audio‐recorded data is analyzed by utilizing methodology introduced and developed in the traditions of Ethnomethodology and Conversation Analysis (CA).FindingsThe authors show how both the consultant and the clients displayed…
Inviting Participation in Organizational Change Through Ownership Talk
2010
This article takes the practitioner’s view toward and focuses on participation through talk within multiparty settings of one process consulting case. From the perspective of discursive psychology, the authors ask what happens in interaction when the consultant is working to put into practice the ideal of active client participation in organizational change. They argue that participation is established when psychological ownership of the process is displayed through talk in interaction. This happens when what the authors call “ownership talk” is used: A person is sharing his or her views, interests, and experiences related to the change process.The authors provide detailed observations and …
Singuliers généralistes. Sociologie de la médecine générale.
2010
International audience; Chacun de nous connaît un médecin généraliste, en qui il peut trouver un interlocuteur privilégié pour ses soucis de santé. En tant que groupe professionnel pourtant, les généralistes ont longtemps été peu considérés dans notre système de soins et restent méconnus : que sait-on des façons d'être généraliste ? de l'évolution de la profession ? Souvent passionnés par leur métier vécu comme un engagement personnel, les médecins généralistes sont-ils satisfaits de leurs conditions de travail et de leur place dans la société? À partir d'enquêtes récentes, des sociologues expliquent ce que sont et font les généralistes dans leur cabinet, ils analysent les "flous du métier"…
