We employed the "dominant-less dominant" research methodological framework, and followed a 4-tier study design: i) a household survey, ii) a semi-structured questionnaire survey, iii) oral history interviews, and iv) key informant interviews.
No extrapolation of the here presented results to higher-tier studies such as aquatic mesocosm studies appears currently possible.
Findings are used to assess re-design for reduced membrane vulnerability to fouling in second-tier studies.
Therefore, the development of empirical multi-tier studies capable of investigating the inter-organisational components of SCF is required.
EFSA points out that an effect size of 20% is 'often taken as the trigger value for further, higher-tier studies' [3].
The differing results of the present field study and the previous laboratory study imply that lower- and higher-tier studies may not be mutually exclusive, but to be used in complementary.
His influence was probably most visible in the environmental risk assessment of chemicals [8 10], such as their regulation in the marine environment (OSPAR process), the effects of endocrine disruptors [11, 12] or their testing in higher-tier studies, especially Terrestrial Model Ecosystems (TMEs) [13 15].
Although other environmental factors influence opportunities for students to acquire competence by the time of their graduation and to progress along the continuum from novice to expert practitioner, few higher-tier studies address these factors in the context of pre-service education.
This additional eligibility requirement and, to a lesser extent, refusals by some eligible participants resulted in some differences in sociodemographic factors between the tier 2 study population in these analyses and the main study participants < 8 years of age.
During the tier 2 study period, the participation rate for the first interview among families of cases and controls < 8 years old was 86% (Metayer et al. 2013).
All acute, chronic, and higher tier aquatic studies of the application dossier are considered for that evaluation.
