In this work, Stark effect measurements have been carried out on several transitions C-13 substituted species of triply-deuterated (D3) methanol. The analysis of the data allowed the determination of the dipole moment components in the first two torsional states of the ground vibrational state of this species. The extrapolated zero field frequencies of the transitions studied have been determined and found to be in excellent agreement with known values. For the torsional ground state the values {in Debye (D)} of μa = 0.9080(9) and μb = 1.4378(10) have been obtained for this species. These values increase for the first excited state as was observed for other species. The dipole moment values are considerably higher than the non-deuterated species. To our knowledge the present study represents the measurement of the most accurate dipole moment values of 13CD3OH for the first time. The results obtained will prove useful for radio astronomy and in understanding of large amplitude internal energy pathways in polyatomic molecules. © 2015 Elsevier B.V. All rights reserved.

This paper examines two related problems that stand in the way of the development of an interdisciplinary project that spans biology and phenomenology. To be sure, each of these disciplines is interested in the body, but there are two ways through which the body may be understood. Biology examines the corporeal or living body (Körper); phenomenology examines the body of lived experience (Leib). Both problems discussed in this paper stem from this two-fold nature of the body. The first concerns the anti-naturalist position taken by Husserl - a position that emphasizes the lived body and rejects any consideration of the corporeal body. Following Roy et al. (1999), I maintain that Husserl's anti-naturalism is no longer necessary. Kurt Goldstein (1934/1995) is used as an example that demonstrates a biological investigation of the corporeal body that is consonant with a phenomenological perspective, a quality which may also be seen in the many references it receives from Merleau-Ponty (1942/1963, 1945/1962). The second problem is that of parallelism - also called the body-body problem (Thompson, 2004). A parallelist collaboration between biology and phenomenology maintains the assumption that there are two bodies that must receive special attention. The problem of parallelism is viewed within the research program of neurophenomenology (Varela, 1996). It is argued that this problem dissolves when it is recognized that there are not two bodies - Körper and Leib - but that these are two ways of recognizing one and the same body. Once again, Goldstein and Merleau-Ponty are used to help describe a two-fold investigation of the body that avoids parallelism and promotes the collaboration which this Special Issue seeks. © 2015 .

The challenges that face African American women living with HIV are immense. African American women continue to be disproportionately infected and affected by this chronic and life-threatening infection in a complex context of individual experience, interactions with the environment, formal and informal support systems, and cultural belief systems. This article identifies the Theory of Silencing the Self (STS) and a widely known model, the Social Ecological Model (SEM), as a synthesized explanatory framework in helping nurses understand how to address research questions and clinical care that is congruent with the experience of African American women living with HIV infection. In synthesizing the components of these two frameworks, an explanation of the relationship between disempowerment and depression in this population will be uncovered as a key component to making relationships at the individual, family, and community level better. Helping African American women living with HIV infection to explore and address how choosing to be silent across their life systems will advance healthcare adherence as we currently know it to improved self-management of a chronic, gender-specific, culturally-bound experience of depression. © 2015 Mary Ann Liebert, Inc.


The sub-millimeter wave (SMMW) spectral measurements using a fast scan backward wave oscillator based spectrometer have been carried out for asymmetrically deuterated methanol CHD2OH (Methanol-D2). Transition frequencies have an estimated uncertainty of about ±50 kHz. Albeit the complexity in the spectra, assignments were possible for a large number of a-type (ΔK = 0) transitions. In the course of the assignment process a strong c-type (ΔK = 1) Q-branch connecting two states of different symmetry species has been identified. This Q-branch assignment is significant because it is forbidden in the normal parent species CH3OH. It becomes allowed in the current species due to the effects of the asymmetry introduced by the off-axis deuterium in the hindering potential to the internal rotation in the molecule. The assignments are rigorously confirmed using combination relations which required the measurement of some other related lines. To our knowledge this is the first time such symmetry breaking transitions are reported in CHD2OH and in fact this is the first time the SMMW spectrum of CHD2OH is being reported. Detailed spectral study of this molecule in the IR and FIR regions is in progress and will be reported elsewhere. Detailed study of the identification optically pumped FIR laser line is underway. © 2016 Elsevier B.V. All rights reserved.

In this work, precise Stark effect measurements have been carried out on several transitions in the first four torsional states of methanol. The Stark shifted transition frequencies for a wide range of steady electric field have been measured with an accuracy of approximately ±10 kHz. Detailed analysis of the data allowed for the determination of the dipole moment components in the first four torsional states of the ground vibrational state. The extrapolated zero field frequencies of the transitions studied have been determined and found to be in perfect agreement with known values. For the torsional ground state the values of μa = 0.8961(2) and μb = 1.4201(9) have been obtained, whereas for the first excited torsional state the corresponding values obtained are 0.9035(1) and 1.4317(5) (These values are in Debye, denoted by D). These values confirm the fact that the dipole moment values increase at a considerable rate as one move toward higher torsional states as seen in previous studies. To our knowledge, this is the first time the most accurate and elaborate dipole moment values of methanol are being reported. © 2015 Elsevier Inc. All rights reserved.
