To establish these findings, we propose a technique for aggregating the results of close elections to obtain "as-if" random variation in majority-party status, allowing us to overcome the central empirical obstacle of selection bias that typically prevents scholars from studying effects of majority-party control.
Moreover, an empirical one-slope path loss model, which considers three-dimensional obstacle shadowing effects, is proposed for simple yet precise coverage calculation.
While there are significant obstacles to empirical research on the effects of Erie and its progeny, this paper out-lines a methodology that may be feasible for future projects in this area.
This article aims at identifying these gaps in knowledge and suggests options for dealing with the obstacles in empirical research in order to advance policies and practices regarding children's medical decision-making competence.
The aim of this article is to offer recommendations for finding a way out of the impasse by means of identifying the gaps in knowledge about children's competence issues and by suggesting options for dealing with the obstacles in empirical research.
The lack of measurement procedures appropriate for settings as complex and dynamic as, for example, the operating room, represents a major obstacle for empirical research in healthcare.
However, despite many studies to improve support, there is virtually no empirical insight into resistance of obstacles that constrain growth over time and how this differs between distinct types of spin-offs.
Very little is known about this, and there may be methodological obstacles to the empirical study of these experiences.
Also, we aimed to identify limitations from guideline adherence in patients with multimorbidity, as perceived by GPs, and to describe their empirical solutions to manage these obstacles.
This focus group study provided new insights into the value general practitioner (GPs) attribute to guidelines when they are applied to patients with multimorbidity, and their empirical solutions to manage perceived obstacles from inappropriate guideline adherence in these patients.
