We test this latter association among older employees and explore to what extent indicators of distinct NLSP modify the association between work stress and depressive symptoms.
Thirteen indicators of distinct risk behaviours were derived from responses to questions collected either during a clinic visit (median age 15 years 5 months) or a postal questionnaire (median age 16 years 7 months).
The difficulties in the interpretation of the conflicting findings on the association between abuse and LBW may be exacerbated by the fact that low birthweight is a heterogeneous indicator of two distinct, although related, processes that may lead to low birthweight, short gestation and restricted fetal growth, making it difficult to elucidate causal effects [ 23].
This raises the question whether neck tenderness is an indicator for distinct subtypes of migraine: patients with neck pain as a simple symptom prior or during the attack without any identifiable changes in the periphery, and patients where the neck plays a crucial role either as a trigger or as a perpetuator for migraine attacks.
The WFD evaluation system and similar indices strongly depend on the presence of distinct indicator taxa at minimum abundances from each group included, which reduces their applicability in ecosystems with high anthropogenic pressure and dominance of neobiota (Arndt et al. 2009).
The use of distinct indicators allows us to analyze in detail the statistical features of the class representatives.
To address this issue we evaluated a panel of distinct indicators of systemic OxS, along with marker of bone formation (bone-specific alkaline phosphatase, BAP) and resorption (C-terminal telopeptide of type I collagen, CTX-1) in a large population sample, including healthy, osteopenic and osteoporotic, postmenopausal women.
In the following, we will show that the number of distinct difference indicator matrices is finite for bounded N, and that the sequence of difference indicator matrices {Δ t′} is stationary Markov and ergodic.
Thus, the number of distinct difference indicator matrices reduces to L=M+1.
The number L of distinct difference indicator matrices is upper bounded by: L leq (N+1 bigg(1+frac{1}{2}N(N+1)bigg)^{N-1} (21).
