Inviting a Hospital Healthcare Team to Change : A Framework for Building Capacity to Provide Intersectional, Trauma-Informed Care

This Organizational Improvement Plan is designed for Open Doors (a pseudonym), a Canadian hospital invested in providing stigma-free, social, and structural determinants-based care to patients who are marginalized from healthcare vis-à-vis previous experiences of exclusion and institutional trauma at healthcare settings. In the context of deepening scrutiny on healthcare institutions for their role in perpetuating systemic oppression and for failure to mitigate inequitable health outcomes for marginalized populations, Open Doors’ commitment to justice-centered care offers a compelling case study in hospital-based strategies for addressing health inequity. The specific Problem of Practice (PoP) addressed is the hospital’s care team’s limited capacity for providing trauma-informed care for patients from diverse communities who face complex, intersecting, and systemic barriers to hospital-based care. Broader systemic failures and contextual factors shaping this PoP are discussed and situated using organizational theory and the recent groundswell in literature on socially conscious caregiving. The need to instigate transformative, adaptive third order change to address the PoP is highlighted using transformative and adaptive leadership theories. Critical appreciative inquiry and dialogic change models are blended to propose a change framework that can mobilize such change within Open Doors’ context. Guided by the change framework and an evaluation-driven design process, a specific solution is detailed, namely, a patient-centered design and learning hub. A detailed change plan is presented, whereby patients, staff, community representatives and leaders are invited into a knowledge-based, dialogic process of co-creating intersectional, trauma informed practices to address a high-priority intersectional area of need for Open Doors.

High-Efficient Video Transmission for HDTV Broadcasting

Before broadcasting a video signal, redundant data should be removed from the transmitted video signal. This redundancy operation can be performed using many video coding standards such as H.264/Advanced Video Coding (AVC) and H.265/High-Efficient Video Coding (HEVC) standards. Although both standards produce a great video resolution, too much data are considered to be still redundant. The most exhaustive process in video encoding process is the Motion Estimation (ME) process. The more the resolution of the transmitted video signal, the more the video data to be fetched from the main memory. This will increase the required memory access time for performing the Motion Estimation process. In This chapter, a smart ME coprocessor architecture, which greatly reduces the memory access time, is presented. Data reuse algorithm is used to minimize the memory access time. The discussed coprocessor effectively reuses the data of the search area to minimize the overall memory access time (I/O memory bandwidth) while fully using all resources and hardware. This would speed up the video broadcasting process. For a search range of 32 × 32 and block size of 16 × 16, the architecture can perform Motion Estimation for 30 fps of HDTV video and easily outperforms many fast full-search architectures

Effect of irrigation with fish farm effluent on two legume crops interplanted with orange trees in a sandy soil

This research was conducted to study the effect of applying three irrigation water quality treatments (Full irrigation using Nile water and 100% NPK fertilizer (Irr I, control); full irrigation using 50% fish farm effluent + 50% Nile water + 50% NPK fertilizer (Irr II); full irrigation using fish farm effluent (Irr III) to two legume crops (faba bean and lupine) interplanted under young orange trees, in addition to the solid planting of all crops in a two-year experiment. The highest yield of the two legume crops under interplanting systems with orange and its solid planting was obtained using only fish farm effluent (Irr III). The highest values of orange yield and water equivalent ratio were obtained when lupine was interplanted under orange trees using Irr III. Similarly, the highest values of land equivalent ratio were obtained for lupine interplanted under orange trees using Irrigation III in the first growing season and faba bean in the second growing in the same treatment. Thus, to reduce pressure on Nile water, we recommend the use of fish farm effluent in irrigation, in general, and use it particularly to irrigate lupine interplanted under orange trees, which increase land and water equivalent ratios.

Effect of Small-molecule Sensitizer on the Performance of Polymer Solar Cell

For improving optical absorption of organic solar cells, a small-molecule sensitizer, as a third material, is usually incorporated into binary solar cell system. In many cases, light harvesting can be improved but on the expense of charge carrier mobility of the solar cells. This obstacle can be addressed through the understanding solar cell physics. In the present work, we try to deeply understand the physics of the long-chain polymer solar cell composed of poly(3-hexylthiophene) (P3HT), as a donor polymer, and [6,6]-phenyl-C61 butyric acid methyl ester (PCBM), as an acceptor molecule. This understanding can be acquired through the effect of coumarin 6 dye (C6), as a small-molecule sensitizer, on optical absorption and photocurrent of the most common solar cell. From optical spectroscopy we found that, the C6 dye, as a small molecule, did not vary conjugation length of the long-chain polymer in the P3HT: PCBM: C6 solar cell. This was indicated from (1) unchanged vibronic structure of the P3HT after adding C6 dye and from (2) matching in the wavelength between absorption peaks of both pristine C6 and P3HT after adding C6 dye into blend. From photocurrent spectroscopy we found that, the incorporation of C6 dye, as a sensitizer, into P3HT: PCBM binary contributed to photocurrent and formed an additional charge carrier generation site through the C6: PCBM combination, which was individually found among with P3HT: PCBM combination in the same solar cell. In the same time, the C6 dye, as a shortchain molecule, restricted the transport of charge carriers generated by P3HT as a result of low hole mobility of the C6 short-chain molecules. Through the present study, the incorporation of a small-molecule sensitizer into polymer solar cell may acquire better understanding for the performance of the most common P3HT: PCBM solar cell.Keywords: Polymer Solar Cells; Device Physics; P3HT: PCBM Solar Cell

Cost-Efficient Storage for On-Demand Video Streaming on Cloud

Video stream is converted to several formats to support the user's device, this conversion process is called video transcoding, which imposes high storage and powerful resources. With emerging of cloud technology, video stream companies adopted to process video on the cloud. Generally, many formats of the same video are made (pre-transcoded) and streamed to the adequate user's device. However, pre-transcoding demands huge storage space and incurs a high-cost to the video stream companies. More importantly, the pre-transcoding of video streams could be hierarchy carried out through different storage types in the cloud. To minimize the storage cost, in this paper, we propose a method to store video streams in the hierarchical storage of the cloud. Particularly, we develop a method to decide which video stream should be pre-transcoded in its suitable cloud storage to minimize the overall cost. Experimental simulation and results show the effectiveness of our approach, specifically, when the percentage of frequently accessed videos is high in repositories, the proposed approach minimizes the overall cost by up to 40 percent.Comment: International IEEE World Forum for Internet of Thing

Estimation of satellite link’s fade margin using non-meteorological technique and worst month analysis

Satellite technology is shifting to higher frequencies such as Q or V-band to cater to greater bandwidth and higher data rates applications such as videoconferencing, internet of things (IoT) and telemedicine. The main challenge in deploying high-frequency bands in heavy precipitation areas is severe rain attenuation. In this paper, a frequency scaling technique was developed to estimate the fade margin at a higher frequency. The worst month analysis was also conducted since the analysis is also important in determining dependable fade margin. The result was evaluated and analyzed using root mean square error (RMSE) and percentage error. The proposed model offers the smallest RMSE and lowest percentage error when compared to all existing prediction models. A dependable fade margin acquired from high-accuracy rain attenuation estimation is very important. This is to apply the best mitigation technique in overcoming rain attenuation in the satellite-Earth link so that, the best system performance can be delivered
