Internet Affairs: Partners’ Perceptions and Experiences of Internet Infidelity
This study utilizes an online survey (open and closed questions) to examine how those whose partners’ have engaged in online affairs define and experience online infidelity. As with offline affairs, respondents were most likely to define sexual (vs. emotional) behaviors as infidelity (e.g., cybersex, exchanging sexual self-images, sharing sexual fantasies online). However, thematic analysis of the qualitative data identified how online behaviors and spaces are confusing and that infidelity is defined more broadly and fluidly in the online context. This potentially explains why participants saw the Internet as facilitating affairs. Findings are discussed in relation to existing literature and study limitations
The Use of Cohort Facebook Pages in MFT Training Programs
The current study explores how private cohort Facebook pages impact a MFT students’ training experience. Limited research has been conducted regarding social media and clinical training programs. Students from national MFT master’s and doctoral programs will be interviewed about their experience with private cohort Facebook pages. Students will participate in focus groups lead by student-researchers in order to increase participation and anonymity. Data will be analyzed using Strauss and Corbin’ s (1990) grounded theory. This research is essential because of the increase of usage of Social Media in today’s society. Graduate programs are implementing the use of Facebook pages for the dissemination of program information and networking between current and former students. However, the impact of social media usage in Clinical Program Training settings among students has not been fully researched
Attachment and couple sexual functioning
Within the last several years, there has been a surge in the publications that focus on attachment within the couple relationships, including how it pertains to infidelity treatment. Despite the interest in couple relationships and attachment, however, a limited amount of literature focuses on how varying styles of attachment manifest in a couple\u27s level of sexual functioning. This study is a response to the need to explore the literature and related gaps in literature
Tunability of Critical Casimir Interactions by Boundary Conditions
We experimentally demonstrate that critical Casimir forces in colloidal
systems can be continuously tuned by the choice of boundary conditions. The
interaction potential of a colloidal particle in a mixture of water and
2,6-lutidine has been measured above a substrate with a gradient in its
preferential adsorption properties for the mixture's components. We find that
the interaction potentials at constant temperature but different positions
relative to the gradient continuously change from attraction to repulsion. This
demonstrates that critical Casimir forces respond not only to minute
temperature changes but also to small changes in the surface properties.Comment: 4 figures;

Critical Casimir effect in classical binary liquid mixtures
If a fluctuating medium is confined, the ensuing perturbation of its
fluctuation spectrum generates Casimir-like effective forces acting on its
confining surfaces. Near a continuous phase transition of such a medium the
corresponding order parameter fluctuations occur on all length scales and
therefore close to the critical point this effect acquires a universal
character, i.e., to a large extent it is independent of the microscopic details
of the actual system. Accordingly it can be calculated theoretically by
studying suitable representative model systems.
We report on the direct measurement of critical Casimir forces by total
internal reflection microscopy (TIRM), with femto-Newton resolution. The
corresponding potentials are determined for individual colloidal particles
floating above a substrate under the action of the critical thermal noise in
the solvent medium, constituted by a binary liquid mixture of water and
2,6-lutidine near its lower consolute point. Depending on the relative
adsorption preferences of the colloid and substrate surfaces with respect to
the two components of the binary liquid mixture, we observe that, upon
approaching the critical point of the solvent, attractive or repulsive forces
emerge and supersede those prevailing away from it. Based on the knowledge of
the critical Casimir forces acting in film geometries within the Ising
universality class and with equal or opposing boundary conditions, we provide
the corresponding theoretical predictions for the sphere-planar wall geometry
of the experiment. The experimental data for the effective potential can be
interpreted consistently in terms of these predictions and a remarkable
quantitative agreement is observed.Comment: 30 pages, 17 figure
Normal and lateral critical Casimir forces between colloids and patterned substrates
We study the normal and lateral effective critical Casimir forces acting on a
spherical colloid immersed in a critical binary solvent and close to a
chemically structured substrate with alternating adsorption preference. We
calculate the universal scaling function for the corresponding potential and
compare our results with recent experimental data [Soyka F., Zvyagolskaya O.,
Hertlein C., Helden L., and Bechinger C., Phys. Rev. Lett., 101, 208301
(2008)]. The experimental potentials are properly captured by our predictions
only by accounting for geometrical details of the substrate pattern for which,
according to our theory, critical Casimir forces turn out to be a sensitive
probe.Comment: 6 pages, 3 figure
Drag forces on inclusions in classical fields with dissipative dynamics
We study the drag force on uniformly moving inclusions which interact
linearly with dynamical free field theories commonly used to study soft
condensed matter systems. Drag forces are shown to be nonlinear functions of
the inclusion velocity and depend strongly on the field dynamics. The general
results obtained can be used to explain drag forces in Ising systems and also
predict the existence of drag forces on proteins in membranes due to couplings
to various physical parameters of the membrane such as composition, phase and
height fluctuations.Comment: 14 pages, 7 figure
