Mindfulness Practice/Mindful Breathing in the Classroom: The Effect on Unwanted Behaviors in the Classroom

Abstract The purpose of this study was to determine whether implementing mindfulness and mindful breathing, in a classroom setting, would decrease the number of unwanted behaviors in that classroom. The setting for this study was a first-grade classroom of 26 in suburban southeast Minnesota. The study took place for six weeks, two weeks without intervention, and four weeks with three mindfulness intervention techniques (mindful breathing, social-emotional stories, and mindful movement/meditation). Data was collected in five ways: an unwanted behavior tally chart, researcher field notes, specialist teacher questionnaires, individual student mindfulness journals, and one-on-one student conversations. After the six-week intervention, the researcher found that three of five unwanted classroom behaviors had decreased. The researcher also found that students were able to put mindfulness practice into action in various real-life situations. The researcher concluded that mindfulness practice does help to decrease unwanted behaviors in the classroom, and will continue to be used in the classroom.

Synthesizing a Fractional v=2/3 State from Particle and Hole States

Topological edge-reconstruction occurs in hole-conjugate states of the fractional quantum Hall effect. The frequently studied polarized state of filling factor v=2/3 was originally proposed to harbor two counter-propagating edge modes: a downstream v=1 and an upstream v=1/3. However, charge equilibration between these two modes always led to an observed downstream v=2/3 charge mode accompanied by an upstream neutral mode (preventing an observation of the original proposal). Here, we present a new approach to synthetize the v=2/3 edge mode from its basic counter-propagating charged constituents, allowing a controlled equilibration between the two counter-propagating charge modes. This novel platform is based on a carefully designed double-quantum-well, which hosts two populated electronic sub-bands (lower and upper), with corresponding filling factors, vl & vu. By separating the 2D plane to two gated intersecting halves, each with different fillings, counter-propagating chiral modes can be formed along the intersection line. Equilibration between these modes can be controlled with the top gates' voltage and the magnetic field. Our measurements of the two-terminal conductance G2T and the presence of a neutral mode allowed following the transition from the non-equilibrated charged modes, manifested by G2T=(4/3)e2/h, to the fully equilibrated modes, with a downstream charge mode with G2T=(2/3)e2/h accompanied by an upstream neutral mode.Comment: 16 pages,4 figure

Perceived relational evaluation : biological, psychological, and physical health correlates

Humans have a fundamental need to belong, and being rejected or devalued elicits strong emotional reactions such as stress and anxiety (Leary, 2001). Low perceived relational evaluation (PRE), as a type of rejection, occurs when one person in a relationship believes his or her significant other does not regard his or her bond with the other person as valuable, close, or important (Leary, 2001). The goal of the research was to examine the interrelations among PRE, cortisol (biological stress), relationship quality, and physical and psychological within dating couples. Undergraduate female students (N = 109) who were involved in dating relationships completed computer-based questionnaires assessing various aspects of their current relationship as well as measures of psychological and physical health symptoms. Immediately prior to and after completing the questionnaires, participants provided saliva samples that were subsequently analyzed for cortisol levels. PRE was expected to be positively correlated with satisfaction and commitment and negatively correlated with physical and psychological health. Relationship stress was expected to be positively correlated with physical health symptoms. Neuroticism was expected to be negatively correlated with cortisol and positively correlated with psychological health and physical health symptoms. Additionally, cortisol was expected to mediate the relationship between PRE and satisfaction, commitment, psychological health, and physical health symptoms. This mediational effect was further predicted to be moderated by neuroticism. PRE was positively correlated with satisfaction and commitment and negatively correlated with psychological distress. Contrary to expectations, PRE was not significantly correlated with physical health symptoms. In addition, cortisol was not significantly related to any of the criterion variables. Therefore, neuroticism was examined as a moderator variable between PRE and the criterion variables. However, no moderation results were significant. Strengths of the research include assessing PRE for its influence on physical and psychological health and obtaining self-report and biological indicators of stress. However, the research was limited by a small sample size and small effect sizes. Future research may benefit from utilizing a longitudinal design as well as including a measure of self-esteem

A Novel Multiple Objective Optimization Framework for Constraining Conductance-Based Neuron Models by Experimental Data

We present a novel framework for automatically constraining parameters of compartmental models of neurons, given a large set of experimentally measured responses of these neurons. In experiments, intrinsic noise gives rise to a large variability (e.g., in firing pattern) in the voltage responses to repetitions of the exact same input. Thus, the common approach of fitting models by attempting to perfectly replicate, point by point, a single chosen trace out of the spectrum of variable responses does not seem to do justice to the data. In addition, finding a single error function that faithfully characterizes the distance between two spiking traces is not a trivial pursuit. To address these issues, one can adopt a multiple objective optimization approach that allows the use of several error functions jointly. When more than one error function is available, the comparison between experimental voltage traces and model response can be performed on the basis of individual features of interest (e.g., spike rate, spike width). Each feature can be compared between model and experimental mean, in units of its experimental variability, thereby incorporating into the fitting this variability. We demonstrate the success of this approach, when used in conjunction with genetic algorithm optimization, in generating an excellent fit between model behavior and the firing pattern of two distinct electrical classes of cortical interneurons, accommodating and fast-spiking. We argue that the multiple, diverse models generated by this method could serve as the building blocks for the realistic simulation of large neuronal networks

A Chronic Care Model Program Incorporating Group Office Visits for Obesity Treatment in Primary Care

Background. Obesity is a chronic disease of epidemic proportions. Primary care providers are on the front line of diagnosing and treating obesity and need better tools to deliver top-notch obesity care. Methods. A pilot randomized trial was conducted to test a chronic care model (CCM) program for obesity compared to usual care. Primary care patients, 18 years and older, with a body mass index (BMI) between 27 and 45 were enrolled. Sixteen weekly 90-minute group office visits were structured with the first 30 minutes encompassing individualized clinical assessments and the final 60 minutes containing the group-based standardized intensive lifestyle training. The primary outcome was weight change at 16 weeks. Secondary outcomes were weight change at 24 weeks, change in diet and physical activity behaviors, self-efficacy for weight control behaviors, and physiologic markers of cardiovascular risk at 16 and 24 weeks. Results. The participants (19 in the active arm and 10 in the control arm) were 49.8 ± 11.5 years old (mean ± SD), 97% women, 55% white, and 41% black. Weight change in the control arm at week 16 was 0.25+ 2.21 kg (mean + SD) and that for the active arm was -5.74 + 4.50 kg (n=16). The difference between the two arms was significant (p = 0.0002). Both the intent-to-treat analysis using the last observation carried forward approach and the analysis including completers only provided similar siginificant results. Conclusions. This study demonstrated that a CCM program incorporating group office visits was feasible and effective for obesity treatment in primary care settings
