Objective:
In this study, we applied conservation of resources theory (Hobfoll, 1989) to explain high rates of depression and posttraumatic stress symptoms (PTSS) among war- and disaster-affected Tamil widows in the Eastern Province of Sri Lanka. We hypothesized exposure to potentially traumatic events and severity of current contextual problems would influence PTSS and depressive symptoms directly and indirectly through loss of psychological (view of self), environmental (sense of community), and energy (physical health) resources.
Method:
Trained research assistants interviewed a convenience sample (N = 381) of women, using established measures of the constructs of interest. Data were analyzed using path analysis in MPlus. The significance of the indirect effects was tested using bootstrapping.
Results:
The model had an acceptable fit (χ2 = 4.06, df = 1, p < .05; Log Likelihood = -3344.26*; AIC = 6760.59; BIC = 6894.64; RMSEA = 0.09; CFI = .99; TLI = .91; SRMR = .02) and explained approximately 38% of the variance in both PTSS and depression. Contextual problems were significantly associated with PTSS and depression both directly and indirectly through deleterious effects on view of self, health status, and sense of community. Degree of trauma exposure was directly associated with indicators of distress.
Conclusion:
Results support the utility of COR theory in this context and hold implications for research and program development. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Long-term Depression
Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
