Co-leadership in Dance/Movement Therapy: An Art-based Literature Review

The co-leadership model is an unseen thread in the current picture of the field of dance movement therapy (DMT). Even if it’s deeply rooted in the development of the field, its significance for the current context of culture-informed and evidence-based practice is still under-investigated. This thesis sheds light on the importance of co-leadership in DMT through a historical review of the development of the field, the rationale of using co-leadership in DMT from neuroscientific, psychological and practical perspectives, and a synthesis of empirical studies on effectiveness of co-leadership in DMT. Co-leadership is a tradition in the field of DMT which prospered when second-generation therapists inherited the work from founders of the field. However, the tradition is vanishing as a single narrative unconsciously dominated the field. In this historic lens, the use of co-leadership is a method to honor the tradition and embrace multiculturalism in the field. Studies in neuroscience and psychology provide theoretical frameworks of how co-leadership strengthens the healing factors in DMT. The co-leadership model also solves practical issues that are commonly faced in DMT sessions. The art-based synthesis of empirical studies showed that the co-leadership model enhances the effectiveness of DMT in terms of providing a holding environment, developing meaningful interventions, and facilitating shared insights. The current thesis serves to advocate for more studies on the usage of co-leadership in the field of DMT

Toward interpreting the IBEX ribbon with mirror diffusion in interstellar turbulent magnetic fields

We investigate the role of the magnetohydrodynamic (MHD) turbulence measured by Voyager in the very local interstellar medium (VLISM) in modeling the Interstellar Boundary Explorer (IBEX) ribbon. We demonstrate that the mirroring by compressible modes of MHD turbulence dominates over that by the mean magnetic field. Based on the new mirror diffusion mechanism identified by Lazarian and Xu for particles with large pitch angles in MHD turbulence, we find that the mirror diffusion can both confine pickup ions and preserve their initial pitch angles, and thus accounts for the enhanced intensity of energetic neutral atoms that return to the heliosphere. The ribbon width is determined by both the range of pitch angles for effective turbulent mirroring and the field line wandering induced by Alfv\'{e}nic modes. It in turn provides a constraint on the amplitude of magnetic fluctuations of fast modes. The field line wandering also affects the coherence of the ribbon structure across the sky. By extrapolating the magnetic energy spectrum measured by Voyager, we find that the injection scale of the turbulence in the VLISM is less than $\sim 500$ au for the ribbon structure to be coherent.Comment: 8 pages, 3 figures, accepted for publication in Ap

On the injection scale of the turbulence in the partially ionized very local interstellar medium

The cascade of magnetohydrodynamic (MHD) turbulence is subject to ion-neutral collisional damping and neutral viscous damping in the partially ionized interstellar medium. By examining the damping effects in the warm and partially ionized local interstellar medium, we find that the interstellar turbulence is damped by neutral viscosity at $\sim 261$ au and cannot account for the turbulent magnetic fluctuations detected by Voyager 1 and 2. The MHD turbulence measured by Voyager in the very local interstellar medium (VLISM) should be locally injected in the regime where ions are decoupled from neutrals for its cascade to survive the damping effects. With the imposed ion-neutral decoupling condition, and the strong turbulence condition for the observed Kolmogorov magnetic energy spectrum, we find that the turbulence in the VLISM is sub-Alfv\'{e}nic, and its largest possible injection scale is $\sim 194$ au.Comment: 9 pages, 2 figures, Accepted for publication in The Astrophysical Journal Letter

Non-Malleable Codes for Small-Depth Circuits

We construct efficient, unconditional non-malleable codes that are secure against tampering functions computed by small-depth circuits. For constant-depth circuits of polynomial size (i.e. $\mathsf{AC^0}$ tampering functions), our codes have codeword length $n = k^{1+o(1)}$ for a $k$-bit message. This is an exponential improvement of the previous best construction due to Chattopadhyay and Li (STOC 2017), which had codeword length $2^{O(\sqrt{k})}$. Our construction remains efficient for circuit depths as large as $\Theta(\log(n)/\log\log(n))$ (indeed, our codeword length remains $n\leq k^{1+\epsilon})$, and extending our result beyond this would require separating $\mathsf{P}$ from $\mathsf{NC^1}$. We obtain our codes via a new efficient non-malleable reduction from small-depth tampering to split-state tampering. A novel aspect of our work is the incorporation of techniques from unconditional derandomization into the framework of non-malleable reductions. In particular, a key ingredient in our analysis is a recent pseudorandom switching lemma of Trevisan and Xue (CCC 2013), a derandomization of the influential switching lemma from circuit complexity; the randomness-efficiency of this switching lemma translates into the rate-efficiency of our codes via our non-malleable reduction.Comment: 26 pages, 4 figure

Interactions between several types of cosmic strings

We study the interaction of several types of static straight cosmic strings, including local strings, global strings, and bosonic superconducting strings with and without magnetic currents. First, we evaluate the interaction energy of two widely separated cosmic strings using the point source formalism and show that the most dominant contribution to the interaction energy comes from the excitation of the lightest mediator particles in a underlying theory. The interaction energy at arbitrary separation distances is then analyzed numerically by the gradient flow method. It turns out that an additional scalar field introduced in the bosonic superconducting string becomes an additional source of attraction. For such a bosonic superconducting string, we find that a string with two winding numbers is energetically favorable compared to two strings with a single winding number in a certain parameter region. Our analysis reveals that a phase structure of bosonic superconducting strings is richer than that of local and global strings and that the formation of bound states at intersections of bosonic superconducting strings is favored.Comment: 38 pages, 19 figure

The integration of hotel interactive lighting systems to support users' visual comfort and activity needs

This study explores the standards of interactive lighting systems in the hospitality industry, specifically those spaces found in hotels, to enhance the experience for customers. Case study analysis was selected as the research methodology to evaluate the lighting quality and capabilities of three commercial hotels in New Orleans as they may inform new hotel interactive lighting capabilities. The study considers three aspects: first, the lighting source, second, the lighting control system, and third, the lighting system structure. Lighting sources are evaluated as they pertain to universal design characteristics. The study focuses on principles 2 and 4 of the seven universal design principles. Principle 2, Flexibility in Use, considers whether the light can be adjusted according to the different needs of users. Principle 4, Perceptible Information, evaluates whether the lighting system can provide sufficient lighting required to support the activities within the space such as route guidance and legibility of important information (Connell et al., 1997). Lighting control is evaluated from the aspect of the user interface considering minimal switching to more state-of-the-art technology to control the lighting quality within a given space. In the lighting structure, the lighting system gradually removes the traditional lighting line based on the single point structure into a wireless chip based on the systematic regional module structure, reducing the difficulty of adjustment, and overall enhancing the efficiency of lighting control. This paper suggests a design standard for interactive lighting systems in hotels based on human behavior patterns and perception levels
