Exploring organizational capacity in a Sport for Development and Peace setting.

Recent Sport for Development and Peace (SDP) scholarship has noted the need for exploring organizational aspects in order to advance SDP theory and practice. One particular unexplored aspect of SDP is organizational capacity. Therefore, the purpose of this study was to explore elements of organizational capacity in SDP organizations operating programming in urban settings outside the top three metropolitan areas (New York, Los Angeles, and Chicago) of the United States. The researcher conducted semistructured interviews with Executive Directors of 17 nonprofit organizations. This qualitative inquiry was guided by Hall et al.’s (2003) three-dimensional framework on organizational capacity. Those three dimensions are: human resources capacity, financial resources capacity, and structural capacity. Findings from this study further our understanding of nonprofit capacity since there is a consensus among scholars that elements within each capacity dimension are context specific. Several elements emerged with each capacity dimension; (a) human resources capacity (board involvement, board recruitment, board retention, paid staff, finding roles, shared values and engagement, staff recruitment, staff retention, staff training, volunteer dependence, volunteer recruitment); (b) financial capacity (financial management, fundraising, financial campaigns, grant funding, special events, other revenue sources, expenses); and (c) structural capacity (partnership management, mutually beneficial relationships, memorandums of understanding, , partnership formation, organizational flexibility, internal structures, organizational culture, access to facilities, internal systems and procedures, strategic planning, plan implementation, and evaluation). Findings also indicated perceived connections between the capacity dimensions. Overall, this study contributes to Svensson and Hambrick’s (in press) call for an empirical and theoretical discussion on the nature of capacity in SDP. Findings in this study extend our understanding of organizational capacity among nonprofit sport organizations and highlight the lived experiences of SDP leaders within existing complex environments. The aim of this research was not only to identify elements of capacity within SDP, but also to explore how SDP organizations are trying to address existing capacity challenges. This study’s findings provide a foundation for future research on the nature of organizational capacity in SDP. Developing a better understanding of capacity in SDP is imperative for designing more effective capacity-building initiatives that help increase the ability of these organizations to fulfill their respective missions

ASIC Implementation of Time-Domain Digital Backpropagation with Deep-Learned Chromatic Dispersion Filters

We consider time-domain digital backpropagation with chromatic dispersion filters jointly optimized and quantized using machine-learning techniques. Compared to the baseline implementations, we show improved BER performance and >40% power dissipation reductions in 28-nm CMOS.Comment: 3 pages, 3 figures, updated reference list, added one sentence in the result section for clarit

Storage and on-demand release of microwaves using superconducting resonators with tunable coupling

We present a system which allows to tune the coupling between a superconducting resonator and a transmission line. This storage resonator is addressed through a second, coupling resonator, which is frequency-tunable and controlled by a magnetic flux applied to a superconducting quantum interference device (SQUID). We experimentally demonstrate that the lifetime of the storage resonator can be tuned by more than three orders of magnitude. A field can be stored for 18 {\mu}s when the coupling resonator is tuned off resonance and it can be released in 14 ns when the coupling resonator is tuned on resonance. The device allows capture, storage, and on-demand release of microwaves at a tunable rate.Comment: 5 pages, 3 figure

Resonant and off-resonant microwave signal manipulation in coupled superconducting resonators

We present an experimental demonstration as well as a theoretical model of an integrated circuit designed for the manipulation of a microwave field down to the single-photon level. The device is made of a superconducting resonator coupled to a transmission line via a second frequency-tunable resonator. The tunable resonator can be used as a tunable coupler between the fixed resonator and the transmission line. Moreover, the manipulation of the microwave field between the two resonators is possible. In particular, we demonstrate the swapping of the field from one resonator to the other by pulsing the frequency detuning between the two resonators. The behavior of the system, which determines how the device can be operated, is analyzed as a function of one key parameter of the system, the damping ratio of the coupled resonators. We show a good agreement between experiments and simulations, realized by solving a set of coupled differential equations.Comment: 10 pages, 6 figure

Period-tripling subharmonic oscillations in a driven superconducting resonator

We have observed period-tripling subharmonic oscillations, in a superconducting coplanar waveguide resonator operated in the quantum regime, $k_B T \ll \hbar\omega$. The resonator is terminated by a tunable inductance that provides a Kerr-type nonlinearity. We detected the output field quadratures at frequencies near the fundamental mode, $\omega/2\pi \sim 5\,$GHz, when the resonator was driven by a current at $3\omega$ with an amplitude exceeding an instability threshold. The output radiation was red-detuned from the fundamental mode. We observed three stable radiative states with equal amplitudes and phase-shifted by $120^\circ$. The downconversion from $3\omega$ to $\omega$ is strongly enhanced by resonant excitation of the second mode of the resonator, and the cross-Kerr effect. Our experimental results are in quantitative agreement with a model for the driven dynamics of two coupled modes
