PBS Ain't So Different: Public Broadcasting, Election Frames, and Democratic Empowerment

Critics often complain that network television election coverage is too short, too superficial, and too focused on "horse race" and strategy. As a result, television news viewers are believed to have an inadequate basis for making intelligent democratic electoral choices. Short, fast-moving, episodic stories and dramatic images convey news frames that fail to inform and empower citizens wishing to make the sort of thoughtful, issue-based choices valued by democratic theorists. Many of these critics laud Public Broadcasting Service (PBS) coverage for its greater story length, use of knowledgeable experts, focus on substantive issues, and lack of dramatic imagery. However, our research shows that despite many differences in the structure of PBS stories, its election news frames are surprisingly similar to those of the oft-criticized commercial networks. Our analysis of ten story frames appearing in PBS and ABC evening news coverage of the 1996 presidential election reveals that public and commercial stories were dominated by horse-race and strategy frames to the exclusion of frames that focus on the prospective and retrospective consequences of candidates' actions and proposals. Our analysis shows that PBS coverage is more comparable to network news coverage than is widely believed, and we suggest that, like network television, PBS frames election news in terms that are disempowering to democratic processes.
Staff Development for Change to Problem Based Learning

Recent years have seen an increase in transformations in educational methods towards Problem Based Learning (PBL). In the process of organizational change, staff development remains one of the key elements. This paper presents a pioneer program in staff development based on PBL learning principles, the Masters in Problem Based Learning in Engineering and Science (MPBL) at Aalborg University, Denmark. Drawing on current experiences and reflection, the paper discusses the outcomes as well as the existing challenges in combining a PBL approach with technology-supported on-line delivery as a strategy for staff development in engineering education.
High-Temperature, Bulk-CMOS Integrated Circuits for a Distributed FADEC System

The greatest roadblock to distributed engine control development is the lack of high-temperature, high-reliability electronic components. Four integrated circuits (ICs) have been developed to provide sensing, actuation, and power conversion capabilities in a high-temperature (over 150°C) environment. Patented high-temperature techniques facilitate designs in a conventional, low-cost, 0.5-micron bulk CMOS foundry process. The HHT104 eight-channel instrumentation IC measures LVDTs, RTDs, thermocouples, and other sensors with up to 12-bit resolution. Dual sigma-delta converters and independent, programmable gain allow simultaneous conversion of two differential-output sensors. A stimulus driver may be used to drive bridge sensors with AC excitation and a temperature-stabilized oscillator provides 1.5- and 24-MHz system clocks for microprocessor use. The HHT212 current driver IC may be used to control two motors in full-bridge configuration or four independent half-bridge loads. Each channel is capable of dri.
Strategic interaction of original equipment manufacturers between outsourcing and purchasing in a quality-differentiated market

Economic globalization has swept the whole world. To focus on their main business, enterprises that are referred to as original equipment manufacturers (OEMs) outsource non-core production activities to contract manufacturers (CMs). By constructing a two-level supply chain consisting of two competing OEMs and one upstream CM, the strategic interaction of the OEMs between outsourcing and purchasing is studied. Specifically, the CM can offer custom- and predefined modes of original equipment manufacturing (namely, CO mode and PO mode, respectively). The former mode enables OEMs to determine product quality, while the latter only allows them to purchase from several quality configurations. The results show that, first, since the CO mode allows the adopter to lead the product design, whether to choose this mode depends on the required R&D cost. Interestingly, however, a lower R&D cost does not necessarily result in the adoption of the CO mode if the product quality difference is small under the PO mode. Second, the optimal purchasing strategy of an OEM is indifferent to the outsourcing mode (CO and PO) of its rival but significantly affected by the quality cost. However, compared to the PO mode, choosing the CO mode would cause the competitor to suffer more profit losses. Third, differing from the prior literature, this paper finds that when the downstream OEM can make quality decisions, although this may lead to profit loss of the contract manufacturer in some channels, it could benefit the CM overall.
A novel single-feed hybrid reconfigurable microstrip patch antenna for 5G mobile communication and radio frequency energy harvesting applications at 28/38GHz

Reconfigurable antennas have received much attention in RF energy harvesting models owing to their selectivity for operating frequency and polarization. The characteristic of having frequency selectivity and polarization selectivity can be termed as frequency diversity and polarization diversity, respectively. This paper investigates a rectenna device with a new proposed topology in order to eliminate coupling between input and output lines and increase the rectification efficiency with the use of single feed hybrid reconfigurable antenna, switch between 28GHz and 38GHz frequency. Moreover, it is designed to charge a rechargeable battery of 1watt(W). The Reconfiguration mechanism is realized by electronically controlling different states of Switches. PIN Diode (as RLC Equivalent circuit) is used as a switch for ON/OFF states. This antenna mainly comprises rectangular shaped patches (28GHz and 38GHz) with Triango-Truncated edge at the corners. Eighteen PIN Diodes are placed symmetrically throughout the antenna presenting as, S1 & S2 for frequency reconfiguration, S3 to S6 & S7 to S10 connects Triango Truncated edge at the corners for polarization reconfiguration, and for radiation pattern reconfiguration at S11 to S14 & S15 to S18 has been used. The proposed antenna model is capable of simultaneously changing, the radiation patterns as clock and anti-clockwise directions at ±90-degree shift in E and H planes, circularly polarized (CP) states among, Linear Polarization (LP), Right Hand Circularly Polarization (RHCP), and Left Hand Circularly Polarization (LHCP). The current design describes using single antenna for energy harvesting and 5G mobile communication application. This would lead to higher output currents, leading to the ability to efficiently charge a wide variety of batteries. A fully functional prototype has been designed, fabricated and its compound reconfiguration characteristics have been validated for simulated and measured results. For validation of results, the experimental results and the simulation results from the proposed mathematical model were made into comparison, and excellent correlation between the measured and simulated results was obtained.
Livestock and Risk Group 4 Pathogens: Researching Zoonotic Threats to Public Health and Agriculture in Maximum Containment

Abstract Maximum-containment laboratories are a unique and essential component of the bioeconomy of the United States. These facilities play a critical role in the national infrastructure, supporting research on a select set of especially dangerous pathogens, as well as novel, emerging diseases. Understanding the ecology, biology, and pathology at the human-animal interface of zoonotic spillover events is fundamental to efficient control and elimination of disease. The use of animals as human surrogate models or as target-host models in research is an integral part of unraveling the interrelated components involved in these dynamic systems. These models can prove vitally important in determining both viral- and host-factors associated with virus transmission, providing invaluable information that can be developed into better risk mitigation strategies. In this article, we focus on the use of livestock in maximum-containment, biosafety level-4 agriculture (BSL-4Ag) research involving zoonotic, risk group 4 pathogens and we provide an overview of historical associated research and contributions. Livestock are most commonly used as target-host models in high-consequence, maximum-containment research and are routinely used to establish data to assist in risk assessments. This article highlights the importance of animal use, insights gained, and how this type of research is essential for protecting animal health, food security, and the agriculture economy, as well as human public health in the face of emerging zoonotic pathogens. The utilization of animal models in high-consequence pathogen research and continued expansion to include available species of agricultural importance is essential to deciphering the ecology of emerging and re-emerging infectious diseases, as well as for emergency response and mitigation preparedness.
Tentacle patterning during Exaiptasia diaphana pedal lacerate development differs between symbiotic and aposymbiotic animals

Exaiptasia diaphana, a tropical sea anemone known as Aiptasia, is a tractable model system for studying the cellular, physiological, and ecological characteristics of cnidarian-dinoflagellate symbiosis. Aiptasia is widely used as a proxy for coral-algal symbiosis, since both Aiptasia and corals form a symbiosis with members of the family Symbiodiniaceae. Laboratory strains of Aiptasia can be maintained in both the symbiotic (Sym) and aposymbiotic (Apo, without algae) states. Apo Aiptasia allow for the study of the influence of symbiosis on different biological processes and how different environmental conditions impact symbiosis. A key feature of Aiptasia is the ease of propagating both Sym and Apo individuals in the laboratory through a process called pedal laceration. In this form of asexual reproduction, small pieces of tissue rip away from the pedal disc of a polyp, then these lacerates eventually develop tentacles and grow into new polyps. While pedal laceration has been described in the past, details of how tentacles are formed or how symbiotic and nutritional state influence this process are lacking. Here we describe the stages of development in both Sym and Apo pedal lacerates. Our results show that Apo lacerates develop tentacles earlier than Sym lacerates, while over the course of 20 days, Sym lacerates end up with a greater number of tentacles. We describe both tentacle and mesentery patterning during lacerate development and show that they form through a single pattern in early stages regardless of symbiotic state. In later stages of development, Apo lacerate tentacles and mesenteries progress through a single pattern, while variable patterns were observed in Sym lacerates. We discuss how Aiptasia lacerate mesentery and tentacle patterning differs from oral disc regeneration and how these patterning events compare to postembryonic development in Nematostella vectensis, another widely-used sea anemone model. In addition, we demonstrate that Apo lacerates supplemented with a putative nutrient source developed an intermediate number of tentacles between un-fed Apo and Sym lacerates. Based on these observations, we hypothesize that pedal lacerates progress through two different, putatively nutrient-dependent phases of development. In the early phase, the lacerate, regardless of symbiotic state, preferentially uses or relies on nutrients carried over from the adult polyp. These resources are sufficient for lacerates to develop into a functional polyp. In the late phase of development, continued growth and tentacle formation is supported by nutrients obtained from either symbionts and/or the environment through heterotrophic feeding. Finally, we advocate for the implementation of pedal lacerates as an additional resource in the Aiptasia model system toolkit for studies of cnidarian-dinoflagellate symbiosis.
SciFab –a wafer‐level heterointegrated InP DHBT/SiGe BiCMOS foundry process for mm‐wave applications

We present a wafer‐level heterointegrated indium phosphide double heterobipolar transistor on silicon germanium bipolar‐complementary metal oxide semiconductor (InP DHBT on SiGe BiCMOS) process which relies on adhesive wafer bonding. Subcircuits are co‐designed in both technologies, SiGe BiCMOS and InP DHBT, with more than 300 GHz bandwidth microstrip interconnects. The 250 nm SiGe HBTs offer cutoff frequencies around 200 GHz, the 800 nm InP DHBTs exceed 350 GHz. Heterointegrated signal sources are demonstrated including a 328 GHz quadrupling source with −12 dBm RF output power. A common design kit for full InP DHBT/SiGe BiCMOS co‐design was set up. The technology is being opened to third‐party customers through IHP's multi‐purpose wafer foundry interface.
Liquid crystal‐based elastomers in tissue engineering

Liquid crystal elastomers (LCEs) play role in tissue engineering investigations, with the combination of orientational ordering generated by liquid crystal (LC) moieties and the elastic capabilities of polymers. Liquid crystal‐based polymer materials require a thorough understanding of their features that set them apart from other smart materials for proper design and application. LCEs offer many advantages for their widespread use in the field of biomaterials, by virtue of their simplicity of processing, anisotropic behavior, and responding to numerous external stimuli. Especially, LCEs have widespread usage in bioengineering applications such as scaffolds due to their biocompatibility, viability, and proliferation properties of these materials. This study introduces a brief overview of the new areas of liquid crystal‐based elastomer applications combining both biomaterials and engineering.
Testing the Impact of a Peer-Delivered Family Support Program: A Randomized Clinical Effectiveness Trial.

OBJECTIVE The effectiveness of NAMI Basics, a peer-led family support program for caregivers of children with mental health concerns, was tested in a sample of caregivers referred to five National Alliance on Mental Illness (NAMI) affiliates in a large southwestern state. METHOD Caregivers of children with mental health concerns (N=111; 69% biological mothers, 45% Hispanic/Latinx, 33% Caucasian, and 12% African American) were randomly assigned to a six-class NAMI Basics course led by peer parents or an 8-week waitlist condition. At baseline and 8 weeks after the course began, all caregivers completed measures assessing services engagement and activation, attitudes toward mental health services, parenting stress, and youth symptoms. Data were analyzed by using linear regression. RESULTS Compared with caregivers in the waitlist condition, NAMI Basics participants reported significant increases in parent engagement and activation, as well as intentions to engage with mental health services. NAMI Basics participants also reported significant decreases in their child's intrapersonal and interpersonal distress, compared with those in the waitlist group. No significant differences were noted on measures of parenting stress, attitudes toward mental health services, or stigma. CONCLUSIONS NAMI Basics affected caregiver outcomes and youth symptoms, as measured by caregiver report, compared with a waitlist control group. Peer-led services, such as NAMI Basics, may increase engagement with effective mental health services for youths and families.
Quantitative comparison of dose–effect and time–course of fluticasone furoate and fluticasone propionate in adult and adolescent patients with persistent asthma: A systematic review and meta‐analysis

This study aimed to quantitatively compare the efficacy of fluticasone furoate (FF) and fluticasone propionate (FP) in adolescents and adults with asthma. We searched the PubMed and EMBASE databases for placebo‐controlled trials that met the inclusion criteria. Pharmacodynamic models were established to describe the time–course of the primary outcome (trough forced expiratory volume in the first second [FEV1]). Secondary outcomes (asthma symptoms, quality of life and exacerbations) were also compared via a meta‐analysis. A total of 14 articles were included in the analysis, involving 6640 subjects. The efficacy plateau of the two drugs could be reached in 2 weeks. The changes from the baseline in trough FEV1 (95% CI) at week 2 of FF at 200 and 100 μg/day were 0.168 L (0.064–0.199) and 0.127 L (0.048–0.163), respectively. The changes from the baseline in trough FEV1 (95% CI) at week 2 of FP at 1000, 500, 250 and 100 μg/day were 0.133 L (0.049–0.171), 0.127 L (0.043–0.163), 0.117 L (0.039–0.150) and 0.093 L (0.032–0.129), respectively. The efficacy of FP had reached a plateau at the maximum evaluated dose (1000 μg/day), while a plateau effect was not seen at the maximum evaluated dose of FF (200 μg/day). In terms of secondary outcomes, the relative effects of the two drugs relative to the placebo were similar and did not show obvious dose–effect relationships. In this study, the time–course and dose–effect characteristics of FP, FF and placebo were quantitatively evaluated, providing necessary quantitative information for asthma‐related guidelines.
Detection of trace volatile organic compounds in spiked breath samples: a leap towards breathomics

Breathomics is the future of non-invasive point-of-care devices. The field of breathomics can be split into the isolation of disease-specific volatile organic compounds (VOCs) and their detection. In the present work, an array of five quartz tuning fork (QTF)-based sensors modified by polymer with nanomaterial additive has been utilized. The array has been used to detect samples of human breath spiked with ∼0.5 ppm of known VOCs namely, acetone, acetaldehyde, octane, decane, ethanol, methanol, styrene, propylbenzene, cyclohexanone, butanediol, and isopropyl alcohol which are bio-markers for certain diseases. Polystyrene was used as the base polymer and it was functionalized with 4 different fillers namely, silver nanoparticles-reduced graphene oxide composite, titanium dioxide nanoparticles, zinc ferrite nanoparticles-reduced graphene oxide composite, and cellulose acetate. Each of these fillers enhanced the selectivity of a particular sensor towards a certain VOC compared to the pristine polystyrene-modified sensor. Their interaction with the VOCs in changing the mechanical properties of polymer giving rise to change in the resonant frequency of QTF is used as sensor response for detection. The interaction of functionalized polymers with VOCs was analyzed by FTIR and UV–vis spectroscopy. The collective sensor response of five sensors is used to identify VOCs using an ensemble classifier with 92.8% accuracy of prediction. The accuracy of prediction improved to 96% when isopropyl alcohol, ethanol, and methanol were considered as one class.
A Ralstonia solanacearum effector targets TGA transcription factors to subvert salicylic acid signaling.

The bacterial pathogen Ralstonia solanacearum causes wilt disease on Arabidopsis thaliana and tomato (Solanum lycopersicum). This pathogen uses type III effectors to inhibit the plant immune system; however, how individual effectors interfere with plant immune responses, including transcriptional reprograming, remains elusive. Here, we show that the type III effector RipAB targets Arabidopsis TGACG SEQUENCE-SPECIFIC BINDING PROTEIN (TGA) transcription factors, the central regulators of plant immune gene regulation, via physical interaction in the nucleus to dampen immune responses. RipAB was required for R. solanacearum virulence on wild type tomato and Arabidopsis but not Arabidopsis tga1 tga4 and tga2 tga5 tga6 mutants. Stable expression of RipAB in Arabidopsis suppressed the pathogen-associated molecular pattern-triggered reactive oxygen species (ROS) burst and immune gene induction as well as salicylic acid (SA) regulons including RBOHD and RBOHF, responsible for ROS production, all of which were phenocopied by the tga1 tga4 and tga2 tga5 tga6 mutants. We found that TGAs directly activate RBOHD and RBOHF expression and that RipAB inhibits this through interfering with the recruitment of RNA polymerase II. These results suggest that TGAs are the bona fide and major virulence targets of RipAB, which disrupts SA signaling by inhibiting TGA activity to achieve successful infection.
Presurgical Orthopedic Treatment of a 3-Year-Old Child with Unoperated Complete Bilateral Cleft Lip and Palate and Protruding Premaxilla

Unoperated patients with bilateral complete cleft lip and palate (BCCLP), who do not receive orthopedic treatment in infancy and present with significant sagittal excess of the premaxilla, are among the most difficult patients to treat. Delay in primary reconstruction reduces the elastic characteristics of the tissues. The resulting rigidity of bony structures accompanied by the wide alveolar and palatal clefts associated with sagittal excess of the premaxilla pose a great challenge for both surgeon and orthodontist. There is no unique protocol for treatment of these conditions. This paper describes the use of orthopedic treatment in an unoperated 3-year-old male child with BCCLP and a protrusive premaxilla whose appearance and function were both severely affected. A modified Meazzini technique, as described in operated BCCLP patients with a downward-displaced premaxilla, was used. The device itself consists of the 2 independent components mutually connected by a 17 × 25 steel arch. The first is an active fan-type expander. The second consists of an acrylic cap covering the premaxilla and 3 brackets used for the steel arch application. They are connected by a rectangular steel 17 × 25 archwire. Reduction of the premaxillary sagittal excess of is carried out with an elastic chain. The use of this orthopedic appliance is a reliable and valuable presurgical treatment in the therapy of children with BCCLP and protrusive premaxilla whose orthopedic and surgical treatment have been delayed.
Motor Imagery Classification Using Inter-Task Transfer Learning via a Channel-Wise Variational Autoencoder-Based Convolutional Neural Network

Highly sophisticated control based on a brain-computer interface (BCI) requires decoding kinematic information from brain signals. The forearm is a region of the upper limb that is often used in everyday life, but intuitive movements within the same limb have rarely been investigated in previous BCI studies. In this study, we focused on various forearm movement decoding from electroencephalography (EEG) signals using a small number of samples. Ten healthy participants took part in an experiment and performed motor execution (ME) and motor imagery (MI) of the intuitive movement tasks (Dataset I). We propose a convolutional neural network using a channel-wise variational autoencoder (CVNet) based on inter-task transfer learning. We approached that training the reconstructed ME-EEG signals together will also achieve more sufficient classification performance with only a small amount of MI-EEG signals. The proposed CVNet was validated on our own Dataset I and a public dataset, BNCI Horizon 2020 (Dataset II). The classification accuracies of various movements are confirmed to be 0.83 (±0.04) and 0.69 (±0.04) for Dataset I and II, respectively. The results show that the proposed method exhibits performance increases of approximately 0.09~0.27 and 0.08~0.24 compared with the conventional models for Dataset I and II, respectively. The outcomes suggest that the training model for decoding imagined movements can be performed using data from ME and a small number of data samples from MI. Hence, it is presented the feasibility of BCI learning strategies that can sufficiently learn deep learning with a few amount of calibration dataset and time only, with stable performance.
