This paper explores a philosophy and connectionist algorithm for creating a long-term, self-motivated developmental robot control system. Self-motivation is viewed as an emergent property arising from two competing pressures: the need to accurately predict the environment while simultaneously wanting to seek out novelty in the environment. These competing internal pressures are designed to driv...
elasticity in an indicator of price sensitivity and its psychological basis has largely been neglected. some scholars in consumer psychology show that advertising decreases price elasticity, while others found a positive relationship between advertising and price elasticity. We hypothesize that two psychological variables, namely set size (in memory) and relative strength of preference (constru...
Background and Objectives: The incidence of rectal cancer is increasing in developing societies, especially in younger age groups. The aim of this study was to evaluate the factors affecting the survival of patients with rectal cancer in the presence of competing risks. Methods: In this retrospective cohort study, the data of 121 patients with rectal cancer during 2001-2017 were studied. De...
Introduction: Breast cancer is one of the most common cancers among women worldwide. Patients with cancer may die due to disease progression or other types of events. These different event types are called competing risks. This study aimed to determine the factors affecting the survival of patients with breast cancer using three different approaches: cause-specific hazards regression, subdistri...
(re) making the procrustean bed? standardization and customization as competing logics in healthcare
recent years have witnessed a parallel and seemingly contradictory trend towards both the standardization and the customization of healthcare and medical treatment. here, we explore what is meant by ‘standardization’ and ‘customization’ in healthcare settings and explore the implications of these changes for healthcare delivery. we frame the paradox of these divergent and opposing factors in te...
We consider a competing spatial growth dynamics permitting that more than one cluster develop in the same environment given by a first-passage percolation model on a Delaunay triangulation of the plane. We focus on the long time behavior of these competing clusters and derive some limit theorems related to the morphology of this multi-type growth process.
Background and purpose: Acute leukemia is a malignancy with a rapidly progressive course of the lymphoid or myeloid cells. A prognostic factor for its survival and treatment is of particular importance in medical research. Therefore, this study aimed at applying competing risk model to compare clinical and pathologic factors in pediatric acute leukemia. Materials and methods: A historical coho...
