Elaborating the assimilation model: Introduction to a special section on case studies of setbacks within sessions and therapeutic collaboration
2016
AbstractThis article introduces a Special Section of case studies that focus on therapeutic collaboration and setbacks in the process of assimilation with the aim of contributing to the evolution of the assimilation model of therapeutic change. The first study examined setbacks in two depression cases (a good vs. a poor outcome) treated with emotion-focused therapy. The second article traced how therapist activities and positions toward internal voices were associated with setbacks in a case treated with linguistic therapy of evaluation. The third article studied contributions of therapeutic collaboration for both advances and setbacks in assimilation in two contrasting cases treated with e…
Tracking of blood vessels motion from 4D-flow MRI data
2022
This paper presents a novel approach to track objects from 4D Flow MRI data. A salient feature of the proposed method is that it fully exploits the geometrical and dynamical nature of the information provided by this imaging modality. The underlying idea consists in formulating the tracking problem as a data assimilation problem, in which both position and velocity observations are extracted from the 4D Flow MRI data series. Optimal estate estimation is then performed in a sequential fashion via Kalman filtering. The capabilities of the method are extensively assessed in a numerical study involving synthetic and clinical data.
Setbacks in the process of assimilation of problematic experiences in two cases of emotion-focused therapy for depression
2016
Research on the assimilation model has suggested that psychological change takes place in a sequence of stages punctuated by setbacks, that is, by transient reversals in the developmental course. This study analyzed such setbacks in one good outcome case and one poor outcome case of Emotion-focused therapy (EFT) for depression.Intensive analyses of five transcribed sessions from each case identified 26 setbacks in the good outcome case and 27 in the poor outcome case. The reason for each setback was classified into one of four categories: balance strategy, exceeding the therapeutic zone of proximal development either induced by the therapist (ZPD-T) or induced by the client (ZPD-C), or spon…
Assimilation, reflexivity, and therapist responsiveness in group psychotherapy for social phobia: A case study.
2017
Objective: This case study examined reflexivity and the assimilation of problematic experiences, especially its progress within and between the Assimilation of Problematic Experiences Scale (APES) Stages 2–3, in group psychotherapy for social phobia. Method: The data consisted of all of one client's turns expressing the two voices of her main problematic experience in 12 sessions, and all replies by the therapist in direct connection to them. The client's utterances were rated on the APES. Results: A detailed analysis of 13 conversational passages revealed that progress in assimilation happened only when the client took a reflexive stance towards her inner experience or outer actions. There…
Description of atmospheric conditions at the Pierre Auger Observatory using the Global Data Assimilation System (GDAS)
2012
Atmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargüe and averaged monthly models, the utility of the GDAS data is shown.
Assessment of the SMAP Level-4 Surface and Root-Zone Soil Moisture Product Using In Situ Measurements
2017
International audience; The Soil Moisture Active Passive (SMAP) mission Level-4 Surface and Root-Zone Soil Moisture (L4_SM) data product is generated by assimilating SMAP L-band brightness temperature observations into the NASA Catchment land surface model. The L4_SM product is available from 31 March 2015 to present (within 3 days from real time) and provides 3-hourly, global, 9-km resolution estimates of surface (0-5 cm) and root-zone (0-100 cm) soil moisture and land surface conditions. This study presents an overview of the L4_SM algorithm, validation approach, and product assessment versus in situ measurements. Core validation sites provide spatially averaged surface (root zone) soil m…
HErZ: The German Hans-Ertel Centre for Weather Research
2016
AbstractIn 2011, the German Federal Ministry of Transport, Building and Urban Development laid the foundation of the Hans-Ertel Centre for Weather Research [Hans-Ertel-Zentrum für Wetterforschung (HErZ)] in order to better connect fundamental meteorological research and teaching at German universities and atmospheric research centers with the needs of the German national weather service Deutscher Wetterdienst (DWD). The concept for HErZ was developed by DWD and its scientific advisory board with input from the entire German meteorological community. It foresees core research funding of about €2,000,000 yr−1 over a 12-yr period, during which time permanent research groups must be established…
Improved meteorology and surface fluxes in mesoscale modelling using adjusted initial vertical soil moisture profiles
2018
The Regional Atmospheric Modeling System (RAMS) is being used for different and diverse purposes, ranging from atmospheric and dispersion of pollutants forecasting to agricultural meteorology and ecological modelling as well as for hydrological purposes, among others. The current paper presents a comprehensive assessment of the RAMS forecasts, comparing the results not only with observed standard surface meteorological variables, measured at FLUXNET stations and other portable and permanent weather stations located over the region of study, but also with non-standard observed variables, such as the surface energy fluxes, with the aim of evaluating the surface energy budget and its relation …
Comparative biochemistry of CO2 fixation and the evolution of autotrophy
1999
Carbon dioxide fixation is a polyphyletic trait that has evolved in widely separated prokaryotic branches. The three principal CO2-assimilation pathways are (i) the reductive pentose-phosphate cycle, i. e. the Calvin-Benson cycle; (ii) the reductive citric acid (or Arnon) cycle; and (iii) the net synthesis of acetyl-CoA from CO/CO2, or Wood pathway. Sequence analysis and the comparative biochemistry of these routes suggest that all of them were shaped to a considerable extent by the evolutionary recruitment of enzymes. Molecular phylogenetic trees show that the Calvin-Benson cycle was a relatively late development in the (eu)bacterial branch, suggesting that some form(s) of carbon assimilat…
An Exploration of Organizational Assimilation Among State-Owned, Private-Owned, and Foreign-Invested Enterprises in China
2017
This study explores organizational assimilation in Chinese organizations. To reflect the Chinese context more accurately, the present study compared employees working in three different kinds of organizations: state-owned enterprises (SOEs), private-owned enterprises (POEs), and foreign-invested enterprises (FIEs). Data collected from 220 full-time employees were analyzed using multiple regression analysis. Regression analyses demonstrated that employees’ level of organizational assimilation was significantly influenced by organizational type: Employees in SOEs reported the highest level and employees in FIEs reported the lowest level of organizational assimilation. peerReviewed
