Towards Validation for Physiological Models in Intervention Planning
"... Abstract. Computer supported treatment planning systems aim at predicting treatment results. Recently attacked challenges base not only on anatomical findings, but include physiological processes. This way, interventions which are highly depending on patient physiology become predictable and can be ..."

be supported in computer based planning. Though the necessity to validate computations used for treatment planning is unquestioned available models lack validation. This contribution discusses challenges for designing a validation study for the example intervention of radiofrequency ablation (RFA) in the liver.
USER ACCEPTANCE OF INFORMATION TECHNOLOGY: TOWARD A UNIFIED VIEW
, 2003
"... Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3) formu ..."

The eight models reviewed are the theory of reasoned action, the technology acceptance model, the motivational model, the theory of planned behavior, a model combining the technology
PDDL2.1: An Extension to PDDL for Expressing Temporal Planning Domains
, 2003
"... In recent years research in the planning community has moved increasingly towards application of planners to realistic problems involving both time and many types of resources. For example, interest in planning demonstrated by the space research community has inspired work in observation scheduling, ..."

the development of a modelling language capable of expressing temporal and numeric properties of planning domains. In this paper we describe the language, PDDL2.1, that was used in the competition. We describe the syntax of the language, its formal semantics and the validation of concurrent plans. We observe
Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,
, 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

A number of special features of the model are discussed (including its use as a basis for the diagnosis of jobs and the evaluation of job redesign projects), and the model is compared to other theories of job design. Work redesign is becoming
Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.
- Journal of Personality and Social Psychology,
, 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

, especially as pertains to their antecedents and consequences. Finally, such a model, if proven valid, should provide a better understanding of the process involved in dropping out of high school, thereby leading to potential insights concerning future interventions with this population. Below, we present
Reverse engineering of regulatory networks in human B cells.
- Nat. Genet.
, 2005
"... Cellular phenotypes are determined by the differential activity of networks linking coregulated genes. Available methods for the reverse engineering of such networks from genome-wide expression profiles have been successful only in the analysis of lower eukaryotes with simple genomes. Using a new m ..."

the organizational network of eukaryotic cells is still a key goal in understanding cell physiology and disease. Genome-wide clustering of gene-expression profiles has provided an initial step towards the elucidation of cellular networks. But the organization of gene-expression profile data into functionally
Self-concordance at work: Toward understanding the motivational effects of transformational leaders.
- Academy of Management Journal,
, 2003
"... We extend existing theories by linking transformational leadership to "self-concordance" at work. In two studies using diverse samples and methods, leader behaviors were associated with follower tendencies to set self-concordant goals. In general, followers of transformational leaders vie ..."

feature of self-concordance. More generally, whereas self-determination theory was developed to account for the effects of contextual forces on intrinsic motivation (Sheldon & Elliot, 1999), the self-concordance model focuses on individuals' proactive and self-generated plans. This focus fits
Constraint Modeling for Curriculum Planning and Validation
, 2008

Learners aim at acquiring expertise about some topic of their own interest, and need to perceive that the curriculum they attend will lead them towards their goal; when this does not happen, they b ..."

Towards Interactive Planning of Coil
, 2009

Instead of open surgery, it allows to reach the lesion of the arteries with therapeutic devices through a catheter. As a particular case, intracranial aneurysms are treated by filli ..."
