Researching peers and disaster vulnerable communities: an insider perspective

Conducting research among peers and communities that a researcher also serves may be both daunting and rewarding. Researching peers may make the researcher feel uncomfortable raising certain questions that are sensitive or that could be construed to be testing their competencies. This paper is inclined more towards showing that it is advantageous to be an insider, whose position can facilitate collection of information that could not have been accessed, or revealed to an outsider. The paper reports on fieldwork conducted in a low-income country in Sub-Sahara Africa as part of a doctoral study with communities affected by disasters and those that work with such communities. The paper demonstrates the complexities of conducting such research and provides some insights that may be useful to insiders, outsiders or “in-betweeners” embarking on fieldwork in low-income countries and among vulnerable population struggling with manifold stresses and shocks

Densities, Viscosities, and Excess/Deviation Properties of the Ternary System 2‑(Methylamino)ethanol + Dimethyl Sulfoxide + Water and the Binary Subsystems

Densities and viscosities of the ternary system 2-(methylamino)­ethanol (MAE) + DMSO + water and its corresponding binary constituents have been measured experimentally over the whole composition range and the temperature range from 293 to 353 K. The excess molar volumes (VE), viscosity deviations (Δη), and excess free energies of activation (ΔG*E) of the binary systems were correlated with the Redlich–Kister equation, while the experimental data of ternary mixtures were represented by using Nagata–Tamura, Cibulka, Singh, and Redlich–Kister equations. For binary mixtures, the VE values of aqueous DMSO and aqueous MAE are negative but positive for the nonaqueous blend of MAE + DMSO. The values of Δη and ΔG*E of aqueous binary systems are positive and negative, respectively, for the binary mixture of MAE + DMSO over the whole composition range and at all temperatures. These behaviors can be interpreted with molecular interactions and structural effects. The V123E and Δη123 values have also been derived from the experimental data of the ternary system. It was found that the V123E values are negative except for the regions highly deficient in water. The values of Δη123 become more positive in both H2O- and MAE-rich regions that were highly poor in DMSO. The observed behaviors indicate that the properties of the ternary system investigated are dominated by binary effects
