Volunteer Identity Salience, Role Enactment, and Well-Being Comparisons of Three Salience Constructs

Two concepts of identity salience are linked to different outcomes in the social psychological literature. Identity accumulation research relates identity importance (one salience concept) to physical and mental health; identity theory connects readiness to invoke an identity (another salience concept) to role enactment. A “cross-over” line of research links volunteer identity importance to frequent enactment of the volunteer role. To integrate these lines of work, I propose that both types of salience spur more frequent role enactment, which in turn benefits well-being. Rating versus ranking measures of salience are contrasted. The identity of community volunteer is the focus, specifically, the role of hospital visitor for the Mended Hearts organization (N = 458). Analyses are disconfirming, instead showing hours spent visiting links to greater visitor identity salience (of both types), which relates to better mental health. Rating measures are more predictive than the ranking measure. Identity salience ...

Continuous V-Grooved AlGaN/GaN Surfaces for High-Temperature Ultraviolet Photodetectors

Three-dimensional heterostructured AlGaN/GaN ultraviolet (UV) photodetectors were microfabricated using V-grooved silicon(111) surfaces and metal organic chemical vapor deposition. This novel sensor platform enabled an increase in sensitivity and operation at high temperatures (up to 200°C). More specifically, texturizing the highly conductive 2-D electron gas using the V-groove sensor surfaces, resulted in higher photodetector sensitivity (57.4% increase at room temperature and 139% at 200°C) compared with conventional designs on planar substrates due to the increased absorption of incident UV light (optical trapping). In addition, a 53% reduction in electrical resistance at room temperature and 27.3% at 200°C were observed due to the increased surface area. The decay time for the non-exponential persistent photoconductivity decreased significantly from 327 to 34 sec as the temperature increased from room temperature to 200°C as a result of the accelerated electron–hole pair recombination (generation) rate. These results support the use of textured AlGaN/GaN sensor platforms for UV detection in harsh environments (e.g., downhole, combustion, and space).
Test Research for Primary Frequency Regulation Function of Large Capacity Thermal Power Units

The quality function of primary frequency regulation of the large capacity thermal power unit in grid directly affects the power quality and grid security,so it is a very important task to improve its performance and response speed. Through field experimental study,it has been confirmed that rapid and lasting primary frequency regulation can be achieved by the manner of coordinated with CCS and DEH,when the large capacity thermal power unit is put into the running mode of boiler-turbine coordinated control.
Ovulation induction with pulsatile gonadotropin-releasing hormone administration in patients with polycystic ovarian syndrome*†

Gonadotropin-releasing hormone (0.025 μ g/kg) was administered intravenously in a pulsatile fashion to four subjects with polycystic ovary syndrome for a total of six cycles. Five of the six cycles culminated in ovulation, although in one course the response occurred too early to be attributed to the therapy alone. No pregnancies resulted. All luteal phases were of normal duration, but progesterone production as manifested by serum progesterone determination was deficient in some. If additional investigation confirms these preliminary findings, this form of therapy may offer a safe and economic alternative for anovulatory patients refractory to clomiphene citrate therapy. The response of the four subjects suggests that pulsatile gonadotropin-releasing hormone administration may override hypothalamic-pituitary dysfunction and result in ovulatory menstrual cycles.
Highly Emissive Excimers by 2D Compression of Conjugated Polymers

Interactions between π-conjugated polymers are known to create ground-state aggregates, excimers, and exciplexes. With few exceptions, these species exhibit decreased fluorescence quantum yields relative to the isolated polymers in liquid or solid solutions. Herein, we report a method to assemble emissive conjugated polymer excimers and demonstrate their applicability in the detection of selected solvent vapors. Specifically, poly(phenylene ethynylene)s (PPEs) with amphiphilic side chains are organized in a Langmuir monolayer at the air–water interface. Compression of the monolayer results in the reversible conversion from a face-on organization of the π-system relative to the water to what appears to be an incline-stack conformation. The incline-stack organization creates a bright yellow emissive excimeric state with increases of 28% in relative fluorescence quantum yields to the face-on monolayer conformation. Multilayers can be transferred onto the glass substrate via a Langmuir–Blodgett method with pr...

Two new Indo-Pacific species in the Eviota nigriventris complex (Teleostei: Gobiidae)

Three species are recognized in the Eviota nigriventris complex, two of them new. Eviota nigriventris Giltay is a species with a red ventral band, edged dorsally with a narrow white line, the ventral band ending in an asymmetrical black mark at the caudal-fin base; E. dorsopurpurea n. sp. is a species with a purple back and head and a black ventral band ending in a semi-circular spot; and E. dorsogilva n. sp. is a species with a black to dark reddish ventral band ending in a semicircular spot and has a cream-colored back. Eviota dorsogilva and E. dorsopurpurea also differ in counts, pectoral-fin base coloration and eye size.
Why class matters less for Asian-American academic achievement

ABSTRACTAsian-Americans are 6% of the U.S. population but comprise more than one-fifth of the entering classes in the country’s Ivy League universities. At prestigious public universities like the University of California, Berkeley, they constitute more than 40% of the student body. Figures like these would be unremarkable if Asian-Americans students uniformly hailed from high socioeconomic backgrounds, but this is not the case. Even the children of Chinese immigrants and Vietnamese refugees whose parents have less than a high school education graduate from college at nearly the same rate as their middle-class peers, pointing to a perplexing Asian-American achievement paradox. Unable to explain the paradox, commentators of various political persuasions have pointed to the role of Asian culture in promoting exceptional academic outcomes. We debunk the specious claim that academic achievement can be reduced to Asian culture. What has been missing from the debate is the role that U.S. immigration law has had...
Development and evaluation of the Expressions of Moral Injury Scale—Military Version

There is consensus that military personnel can encounter a far more diverse set of challenges than researchers and clinicians have historically appreciated. Moral injury (MI) represents an emerging construct to capture behavioural, social, and spiritual suffering that may transcend and overlap with mental health diagnoses (e.g., post-traumatic stress disorder and major depressive disorder). The Expressions of Moral Injury Scale-Military Version (EMIS-M) was developed to provide a reliable and valid means for assessing the warning signs of a MI in military populations. Drawing on independent samples of veterans who had served in a war-zone environment, factor analytic results revealed 2 distinct factors related to MI expressions directed at both self (9 items) and others (8 items). These subscales generated excellent internal consistency and temporal stability over a 6-month period. When compared to measures of post-traumatic stress disorder, major depressive disorder, and other theoretically relevant constructs (e.g., forgiveness, social support, moral emotions, and combat exposure), EMIS-M scores demonstrated strong convergent, divergent, and incremental validity. In addition, although structural equation modelling findings supported a possible general MI factor in Study 2, the patterns of associations for self- and other-directed expressions yielded evidence for differential validity with varying forms of forgiveness and combat exposure. As such, the EMIS-M provides a face valid, psychometrically validated tool for assessing expressions of apparent MI subtypes in research and clinical settings. Looking ahead, the EMIS-M will hopefully advance the scientific understanding of MI while supporting innovation for clinicians to tailor evidence-based treatments and/or develop novel approaches for addressing MI in their work.
Development of a tunable high repetition rate XUV source for time-resolved photoemission studies of ultrafast dynamics at surfaces

The characterization of surfaces using photoelectron spectroscopy or photoemission electron microscopy provides sensitive probes of surface structure and electronic properties. Conventional extreme ultraviolet (XUV) light sources used for photoemission do not have ultrafast time resolution, which inhibits applying these techniques to the study of surface dynamics on their natural time scale. The high harmonics (HHG) of intense femtosecond laser pulses are capable of providing ultrashort XUV pulses for photoemission. However, for pulse-based photoemission measurements it is necessary to limit the density of electrons emitted by each pulse to prevent detrimental spacecharge effects. Therefore, to maintain reasonable data acquisition rates, the pulses must occur at a high repetition rate. Since the HHG process requires high peak fundamental laser powers, repetition rates have typically been limited to well below 1 MHz. In our lab, we can perform time-resolved XUV photoemission experiments at an 87 MHz repetition rate using a cavity-enhanced HHG source. Harmonics are generated at 87 MHz by resonantly enhancing a Yb:fiber laser capable of 1 μJ pulses in a passive optical cavity to pulse energies > 100 μJ. Average photon fluxes of up to 7x10 11 photons/s in a single isolated harmonic are delivered to a surface science end station. This delivered flux and repetition rate are comparable to a synchrotron light source, but with pulse durations nearly 1000 times shorter. In this paper, we discuss critical details of the source and its performance.
Teaching Students Self-Advertising/Marketing Skills in the Age of Social Media: Designing an Experiential Exercise:

After finding that college students are unlikely to use social media for self-advertising/marketing, this paper presents a pedagogical tool to help advertising educators teach them how. The experiential exercise is based on an e-marketing planning process where students conduct a situation analysis, differentiate their brand and set forth personal goals and objectives. Students use social media to promote themselves to employers, their small businesses, hobbies or social causes. Students consider the exercise to be effective in deepening their understanding of how strategic planning can enhance their self-marketing/advertising skills.
Serum and vaginal fluid antibodies against the major iron-regulated protein in women with gonococcal pelvic inflammatory disease or uncomplicated infection

We measured antibodies against the Neisseriae major iron-regulated protein (MIRP) in 140 sera and 134 vaginal wash fluids serially obtained from 24 women who had pelvic inflammatory disease (PID) or uncomplicated infection (UGC) due to Neisseria gonorrhoeae. Reactive serum Ig levels were: IgG, 2.3 to > 30 µg/ml; IgM, 0 to 48 µ/ml; IgA, 0 to < 0.01 µg/ml. Vaginal wash fluid levels were: IgG, 0 to 4.8 µg/ml; IgA, 0 to 0.437 µg/ml. The reactive Ig levels were higher in patients with previous gonococcal infections and when repeated infections occurred during the study. One of the patients had repeated PID.
Reduced rate of rod outer segment disk synthesis in photoreceptor cells recovering from UVA light damage.

Purpose. Recovery of photoreceptor cells after light damage is thought to involve the physiologic process of disk renewal. However, only indirect evidence is available to support this hypothesis. The present study sought to examine more direcdy the mechanisms of photoreceptor cell recovery by quantitatively assessing the rate of rod outer segment (ROS) disk syntfiesis in retinas damaged by ultraviolet-A (UVA) light. Methods. Pigmented rats were anesthetized, and their right eyes were exposed for 1 hour to a uniform field of UVA light at a dose of 6 J/cm 2 . Animals were returned to their dim cyclic light environment and were allowed to recover for various time points up to 42 days, at which time their eyes were enucleated for histologic examination and quantification of outer nuclear layer (ONL) thickness. Seven days before the 6- and 21-day time points, some animals were intravitreally injected with 3 H-leucine in both eyes, and these eyes were used to analyze autoradiographically the rate of ROS disk synthesis. Results. ROS disk synuhesis in UVA-exposed eyes was 43% slower relative to nonexposed controls in the more severely damaged superior retina at postexposure day 6. Ultrastructural observations revealed a sharp demarcation between damaged and recovered ROS disks at this time. At postexposure day 21, there was a marked recovery in outer segment structure despite a further decrease in ONL thickness and a continued slow rate of disk synthesis. In the less severely damaged inferior region of the retina, the rate of disk syndiesis was not altered by UVA exposure, although mild ROS disruption was evident at the earlier time points. Conclusions. These findings indicate that the rate of ROS disk synthesis is slowed in moderately damaged photoreceptor cells even though they eventually fully recover in structure. A slowdown of this rate after UVA exposure may be an adaptive change geared toward recovery mechanisms, or it may simply be a manifestation of cellular damage.

Red-Emitting Ru(II) Metal–Ligand Complexes

A series of Ru(N–N)2(dcbp or mcmabp) complexes were synthesized where N-N represents a diimine ligand, dcbp is 4,4′-dicaboxylic 2,2-bipyridine, and mcmabp is 4,4′-2,2′-bipyridine monocarboxy amide. The N-N ligand was either 2,2′-bipyridine (bpy), 4,4′-dimethyl-2,2′-bipyridine (dmbp), or 4,4′,5,5′-tetramethyl-2,2′-bipyridine (tmbp). We observed a red shift in both the absorption and emission with the presence of dcbp in the mixed ligand complex when compared to Ru(bpy)3. Conversion of one of the carboxylic groups in dcbp to amide resulted in further red shifts. A red shift in the absorption and the emission was also observed with increasing numbers of electrons donating methyl substitutions on bpy. The lifetimes of the complexes decreased as expected with the red shift emission. The tris heteroleptic Ru (tmphen)(tmbp)(dcbp or mcmabp) were the most red-shifted among the complexes. Because of the red shift in the absorption, the maxima in the fundamental anisotropies of the mixed ligand Ru complexes are now coincident with the maxima in the absorption. Overall we have been able to make an Ru complex which emits at about 700 nm in all aqueous environment and has a lifetime of about 220 ns.
Kinematics and Dynamics in a Hierarchically Organized Robot Control System

Research on sensor based control of robots is currently experiencing significant growth because of application areas such as flexible manufacturing and space. The majority of the research efforts have targeted low-level robot control and many algorithms have been proposed for position and/or force control in which sensors play an integral role. The National Bureau of Standards (NBS) has developed a hierarchically organized robot control system where task decomposition, world modeling, and sensory processing are explicitly represented. This paper describes how kinematics and dynamics of manipulators are used in a hierarchically organized robot control system.
Analysis and optimization of ducted wind turbines

Abstract Wind-lens turbines offer the potential for better energy efficiency and better suitability for urban and suburban environments compared to unshrouded or bare wind turbines. Wind-lenses, which are typically comprised of a diffuser shroud equipped with a flange, can enhance the wind velocity at the rotor plane due to the generation of a lower back pressure. In this article, the wind-lens efficiency is increased by designing the shroud and turbine shape as well as flange height through an optimization process that seeks to maximize the power while minimizing drag and thrust forces. The employed optimizer is a multi-objective genetic algorithm (MOGA). Bezier curves are used to define the chord and twist distribution of the turbine blades and a piece-wise quadratic polynomial is utilized to define the shroud shape. The power, thrust, and drag coefficients are calculated by solving the Reynolds-averaged-Navier-Stokes (RANS) equations with the k − e turbulence model for the flow within and around the diffuser augmented wind turbine using the open source code software OpenFOAM. To reduce the computational cost, the turbine rotor itself is modeled by incorporating blade element momentum model body forces into the RANS equations. Realistic rotor data for the sectional lift and drag coefficients for all angles of attacks are utilized via look-up tables. Grid convergence studies for verification and comparisons with experiments for validation are carried out to demonstrate that the adopted methodology is able to accurately predict the performance of a wind-lens prior to performing shape optimizations. It will be demonstrated that the resulting optimal designs yield significant improvements in the output power coefficient.
AlInN for Vertical Power Electronic Devices

The known benefits and challenges of AlInN as a next-generation power electronic semiconductor are presented. Al x In1− x N is lattice matched to GaN at ${x} = {0.82}$ and has the advantages of an available substrate, a wide bandgap (~4.4 eV), and high mobility (~450 cm2 $/\text {V} \cdot \text {s}$ ). The power figure of merit (FOM), determined using empirical and theoretical values of mobility and estimated critical electric fields determined from reported bandgaps, spans from ~20% to 130% times greater than GaN. In order to realize and precisely determine these high AlInN FOM values, experimental challenges will need to be overcome such as polarization-induced electric fields and bandgap discontinuities at AlInN/GaN interfaces, and controlling carrier concentration levels.
GP107 Integrated care for 22q11 deletion syndrome in ireland – meeting children’s needs through enhanced care co-ordination

Background 22q11 Deletion Syndrome is a complex, multi-system disorder with a prevalence of 1 in 2000 to 4000 people, making it the most common microdeletion described. Affected children may present with a diverse range of medical conditions and they are extremely vulnerable to a range of physical and intellectual disabilities as well as psychiatric illness throughout their lifespan. Consensus surveillance guidelines were developed, and last updated in 2017, in the U.K. to establish ‘a comprehensive and universally agreed lifelong care plan for people with 22q11DS’. Medical care for this population is frequently fragmented, and a need for a dedicated clinic in Ireland was identified by both medical professionals caring for these children and their families through 22q Ireland parent support group. Aims Our aim is to review the needs of children with 22qDS at the time of their first dedicated tertiary clinic review with reference to the consensus guidelines and establish if a dedicated clinic can identify and address unmet needs within this population. Methods The outcomes of all first clinic appointments since the establishment of the new clinic in October 2017 to January 2019 were reviewed. Previous specialty input along with referrals made and investigations requested were recorded. Results In the first 6 months of the 22q11DS Clinic 17 children were assessed. This attendance rate was 94% and 29% of this group had their appointment co-ordinated with another specialist on the same day. Overall, 46 children have been seen to date. Following their first assessment, in accordance to the guidelines and clinical need, overall 82% required surveillance investigations, including: blood testing (66% of children), renal ultrasound (30%) and X-Ray spine (9%). Specialist referrals were needed in 73% of children, to a variety of services, most commonly to mental health (48%), dental (20%), cardiology (18%), immunology (14%), cleft team (14%), ophthalmology (14%), audiology (9%), endocrine (7%) and orthopaedics (7%). Conclusion We have identified multiple areas of unmet need with reference to best practice guidance in this dedicated clinic. It is hoped that we can improve care co-ordination further by engaging other specialists to run clinics on the same day, appoint a nurse specialist and adopt a clear care pathway, tailored to the Irish healthcare system using a life course approach to ensure the regular monitoring and anticipation of issues and early intervention that helps in maintaining health, well-being and quality of life.
Objectifying the Risk of Vascular Complications in Gluteal Augmentation With Fat Grafting: A Latex Casted Cadaveric Study.

Background Fat transfer is the most popular means of gluteal augmentation. However, this procedure may be complicated by pulmonary fat embolisms (PFEs). Of 135 PFEs out of 198,857 cases reported by the Aesthetic Surgery Education and Research Foundation task force, 32 were fatal, contributing to the mortality risk of this procedure being as high as 1:2351. Objectives The aim of this study was to generate an anatomic map of the 3-dimensional location and variability in size of the gluteal region vessels. Methods Twenty cadaveric gluteal regions were dissected. The aorta, venae cavae, popliteal, and saphenous veins were cannulated and injected with colored latex. Dissection was performed subcutaneously, in the gluteus maximus (GM), and submuscularly to evaluate the number and vascular distribution of all the vessels. Vessels were mapped on an XYZ axis. Results The subcutaneous plane, containing 25 vessels on average, had the smallest vessel diameters (artery, 0.9 [0.3] mm; vein, 1.05 [0.22] mm). The GM vein diameter was 1.3 [0.3] mm. Branches of the inferior gluteal vessels had arterial and venous calibers of 2.2 [0.04] mm and 3.5 [0.99] mm, respectively. Superior gluteal artery and vein branches were 1.8 [0.2] mm and 3.85 [1.9] mm in diameter, respectively. Superior and inferior gluteal vein diameters were 7.61 [2.24] mm and 13.65 [6.55] mm, respectively. Conclusions The deeper and more medial planes of the gluteal region house larger, more prominent vessels. This research objectifies and is consistent with recommendations made by various recent task force reports to limit fat transfer to the subcutaneous plane.
Ozone-Induced Cleavage of Endocyclic C═C Double Bonds within Steroid Epimers Produces Unique Gas-Phase Conformations

Herein we demonstrate the first application of ozone-induced cleavage of endocyclic C═C double bonds for improved steroid isomer separation using ion mobility-mass spectrometry. Steroids represent a challenging biomolecular class for ion mobility (IM) separations due to their structural rigidity and subtle stereochemical differences. In this work, we compare the effects of ozonolysis on the relative mobilities of a model stereoisomer pair, testosterone and epitestosterone. A solution-phase ozonolysis approach is used due to its simplicity, relatively low cost, and potential for rapid, online analysis. Despite the presence of solvent-based addition products, we observe that these steroids undergo an ozone-based cleavage resulting in unique, stable gas-phase conformations. The resulting resolution between testosterone and epitestosterone, with collision cross section values of 176.6 and 193.3 A2, respectively, demonstrates a significant improvement in comparison with previous IM-based approaches. The significantly smaller conformation observed for epitestosterone is stabilized by a three-point interaction between the oxygen-containing functional groups and a sodium ion; this same conformation cannot be sterically achieved by testosterone. Identification of this specific structural difference is strengthened by experimental results showing the disappearance of this conformation following in-source water loss, which eliminates the potential for that three-point interaction. Computational modeling of the lowest energy gas-phase structures for these ozone products corroborates the experimental results. In conclusion, this approach provides tremendous potential as a rapid IM separation method for steroid isomers and other endocyclic C═C double bond containing molecules.

Sustainable technologies for seaweed conversion to biofuels and bioproducts

Abstract Seaweeds are attractive candidates to supply the future sustainable, photosynthetic, bioenergy feedstocks thanks to their cultivation promise in offshore marine farms, with year-round production, and no external nutrient requirements. Despite this potential, there are significant challenges associated with realizing both the cultivation and harvesting logistics, as well as in developing an efficient conversion platform to fuels and products. Effective and scalable and economically viable conversion processes tailored to a seaweed are discussed in detail and gaps on identified needs for yield and efficiency improvements. Among the conversion processes discussed here, anaerobic fermentation of seaweeds to bioenergy products, including organic acids and biomass, is promising to disrupt the current bioenergy landscape.

Packaging Liquidity: Blind Auctions and Transaction Cost Efficiencies

The costs of implementing investment strategies represent a significant drag on the performance of mutual funds and other institutional investors. It is the responsibility of institutional investors, and in the interests of the individual investors they represent, to seek market mechanisms that mitigate trading costs. We investigate one such liquidity provision mechanism whereby liquidity demanders auction a set of trades as a package directly to potential liquidity providers. A critical feature of the auction is that the identities of the securities in the package are not revealed to the bidder. We demonstrate that this mechanism provides a transactions cost savings relative to more traditional trading mechanisms for the liquidity demander as well as an efficient way for liquidity suppliers to obtain order flow. We argue that the cost savings afforded this new mechanism are due to the potential for low-cost crosses with the bidder's existing inventory positions and through the longer trading horizon, and superior trading ability, of the bidders. This research suggests that the ability to innovate via new liquidity provision mechanisms can provide market participants with transaction cost savings that cannot be easily duplicated on more traditional exchanges.
Use of rodenticide bait stations by commensal rodents at the urban-wildland interface: Insights for management to reduce nontarget exposure.

BACKGROUND Pest management professionals use anticoagulant rodenticides, usually placed in tamper-resistant bait stations, to control commensal rodents, but significant concerns remain about exposure of nontarget species, especially at the urban-wildland interface. We deployed digital cameras to monitor use of bait stations placed in 90 residential yards across Orange County, California, USA. Two bait stations, supplied with nontoxic bait, were monitored in each yard for approximately 30 consecutive days during two camera-trapping sessions between December 2017 and March 2019. One station was placed on the ground, while the other was elevated 1-1.5 m to determine if elevating stations could reduce nontarget exposure. RESULTS Black rats (Rattus rattus L.) were present at 80% of sites, with mean activity ranging from 0 to 9.6 h each night. There were no significant differences between elevated and ground stations in the time to discovery, time to bait station entry, or nightly activity of rats. Rats discovered bait stations more quickly, and mean nightly activity was greater, in yards where rats were detected more frequently. Although native rodents visited and entered bait stations occasionally, they were relatively rare among our sites (13.3%), and were detected five times less often at elevated stations compared to those on the ground. Yards visited by these rodents were significantly nearer to areas of green open space and natural vegetation, and tended to have no significant barriers to entry, e.g. solid fences or walls. CONCLUSIONS By elevating bait stations and avoiding placing rodenticides in yards that are likely to be visited by wildlife, pest management professionals may be able to reduce the risk of nontarget exposure, including secondary poisoning of predators and scavengers, while still providing effective control of commensal pests. © 2021 Society of Chemical Industry.
Tête-à-tête with CtBP dimers

Jecrois et al. (2020) use cryoelectron microscopy to illuminate the tetrameric conformation of the CtBP2 transcriptional corepressor, a protein frequently overexpressed in human cancers. The in vivo functional characterization of tetramer-destabilizing mutants indicates that tetramerization is a physiologically important process, critical for CtBP control of gene regulation and cell migration.
Practical and Theoretical Considerations Concerning Treatment of Bacterial Pneumonia in Feedlot Cattle, With Special Reference to Antimicrobic Therapy

When effective antimicrobic therapy can be initiated on the first day that clinical signs are evident to an experienced observer and continued for 48 hours after fever, dyspnea and toxemia have abated, and if appropriate shelter, nutrition and nursing care are provided, mortality from acute, uncomplicated bacterial pneumonia in feedlot cattle will be negligible. Mortality is increased when disease detection is inadequate, resulting in delayed treatment, when ineffective antimicrobics are utilized, or when inappropriate dosages, routes of administration or treatment intervals are selected, and when treatment is irregularly administered or prematurely terminated. Failure to promptly reinstitute treatment when relapses occur is often a factor in excessive mortality. Sick cattle should be kept dry and provided with shelter from cold winds or hot sun. Sick cattle penned together should be of similar size and should not be overcrowded. At least 12 linear inches and preferably 24 linear inches of feed bunk space should be provided per animal.

Effects of desmopressin acetate administration in healthy dogs receiving prednisolone

BACKGROUND Glucocorticoids are used for a variety of purposes in veterinary medicine but often are associated with clinically important adverse effects. Polyuria and polydipsia are the most frustrating adverse effects noted by owners. OBJECTIVE To determine whether administration of desmopressin ameliorates polyuria and polydipsia associated with prednisolone administration. ANIMALS Seven healthy adult Walker Hounds. METHODS Prospective hypothesis testing study. Daily water intake and urine specific gravity (USG) were measured in dogs under 4 separate sequential conditions: no medications (C), prednisolone only (P), prednisolone and desmopressin (PD), and prednisolone after discontinuation of desmopressin (PAD). RESULTS When compared to baseline, 6 of 7 dogs became polydipsic after administration of prednisolone (0.5 mg/kg PO q12h). When desmopressin (5 μg/dog SC q12h) was administered to dogs receiving prednisolone, significant decreases in water intake and serum sodium concentration occurred, and USG increased significantly. CONCLUSIONS AND CLINICAL IMPORTANCE Administration of desmopressin to dogs receiving prednisolone significantly decreased water intake and serum sodium concentration, and increased USG. Our results suggest that, in some dogs, desmopressin ameliorates the most important adverse effect of prednisolone noted by owners, but that hyponatremia is an important complication associated with desmopressin use.
Fantasies of the Anthropocene

Fantasies of the Anthropocene focuses on the rise of Marvel’s Cinematic Universe as the most popular and influential producer of cinematic superhero fantasy. Chapter Four reads the MCU’s overarching narrative from Iron Man (2008) to Avengers: Endgame (2019) in terms of the concurrent social, political, and environmental conditions as a world in crisis. Focus then moves to a close reading of Iron Man, the flagship superhero that launched a thousand toy ships. Iron Man, aka Tony Stark, symbolizes the neoliberal superhero par excellence ironically while at the same time celebrating the power of obscenely rich, witty, technological Superhero-as-ideological signifier. He is the self-made man, the American Dream writ large, and he and his story are concerned with weapons development and private property. Tony Stark’s drama unfolds as a psychotherapeutic bait and switch in which he learns to forgive his father and metonymically enforces the restorative ideology grounded in the symbolic Law and the Name of the Father.

TIED TOGETHER: BUILDING RELATIONAL WELL-BEING AND REDUCING SOCIAL ISOLATION THROUGH PLACE-BASED PARENT EDUCATION

Recent research has begun to shed light on the role community organizations can play in fostering relational well-being, particularly among low-income parents living high-poverty neighborhoods. However, less well understood are the organizational, programmatic, and neighborhood factors that contribute to the formation of new social network connections among participants in these settings or the nature of connections developed. This qualitative study examines the efforts of one neighborhood-based human service organization to counter the effects of social isolation through a place-based parent education initiative. Findings from 69 interviews suggest that for participants the program served as transformative learning environment that challenged existing narratives about public housing residents and fostered the development of a positive shared identity as parents. Formal structures and informal opportunities in the neighborhood supported the development and maintenance of new social connections and served as the foundation for an ongoing community of practice among participants.
Arabinosylation Plays a Crucial Role in Extensin Cross-linking In Vitro

Extensins (EXTs) are hydroxyproline-rich glycoproteins (HRGPs) that are structural components of the plant primary cell wall. They are basic proteins and are highly glycosylated with carbohydrate accounting for >50% of their dry weight. Carbohydrate occurs as monogalactosyl serine and arabinosyl hydroxyproline, with arabinosides ranging in size from ~1 to 4 or 5 residues. Proposed functions of EXT arabinosylation include stabilizing the polyproline II helix structure and facilitating EXT cross-linking. Here, the involvement of arabinosylation in EXT cross-linking was investigated by assaying the initial cross-linking rate and degree of cross-linking of partially or fully de-arabinosylated EXTs using an in vitro cross-linking assay followed by gel permeation chromatography. Our results indicate that EXT arabinosylation is required for EXT cross-linking in vitro and the fourth arabinosyl residue in the tetraarabinoside chain, which is uniquely α-linked, may determine the initial cross-linking rate. Our results also confirm the conserved structure of the oligoarabinosides across species, indicating an evolutionary significance for EXT arabinosylation.
A Test of Three Competing Theoretical Models of Delinquency Using Structural Equation Modeling

ABSTRACT This study of 837 adolescents from five public high schools is designed to examine three competing theoretical models of crime using structural equation modeling. The models are based on general theory, social relations theories, and an age-graded integration of these theories. These theoretical models are the preeminent explanations of youthful crime. Gender differences in theoretical models are examined. Clearly, the best-fit model for males and for females is the age-graded integrative model. Caregiver attachment is the strongest predictor of crime among females, whereas this factor is not relevant for males. Religiosity and social support also are more important for females than for males. Among males, the primary predictors are peer association, low self-control, care-giver monitoring, isolation, self-identity, and social deficits. Implications of the findings are discussed in relation to theory and gender.
The dynamics of parental care of Copeina arnoldi (pisces, characidae)

The parental behavior of 10 isolated male Copeina arnoldi with single spawns was monitored throughout the parental cycle. Parental splashing frequency decreased daily after spawning. Daily mean splashing frequencies observed ranged from 38.5 to 0.2 splashes per hour. No diurnal cycle of parental splashing could be discerned. Bouts of parental splashing were found to be spaced randomly throughout the observation periods except at high activity levels when the bouts became uniformly spaced. The number of splashes per bout was not significantly different between males or between days of the parental cycle. Properties of the underlying neurophysiological mechanisms controlling parental behavior in C. arnoldi as indicated by the behavioral output are discussed.
Pituitary adenylate cyclase activating polypeptide enhances rapid eye movement sleep in rats

Pituitary adenylate cyclase activating polypeptide (PACAP), a member of the vasoactive intestinal polypeptide family, was tested for its effects on sleep in adult male Sprague-Dawley rats. PACAP was injected via intracerebro-ventricular cannula at light or dark onset; sleep and brain temperature (Tbr) were recorded for 12 h after injection. Rapid eye movement sleep (REMS) was significantly enhanced by 30 pmol, but not 3 or 300 pmol PACAP injected at dark onset. Non-REMS was not influenced by 3, 30, or 300 pmol PACAP Sleep and Tbr were not influenced by 3 or 30 pmol PACAP injected at light onset.
Disambiguating the Components of Emotion Regulation.

Affective neuroscience and cognitive science approaches are useful for understanding the components of emotion regulation; several examples from current research are provided. Individual differences in emotion regulation and a focus on the context of emotion experience and expression provide additional tools to study emotion regulation, and its development, from a biobehavioral perspective.
The effect of fetal neck position on nuchal fold thickness.

Objective: Our purpose was to determine whether ultrasonographic measurements of nuchal fold thickness are affected by the position of the fetal neck. Study Design: Fetal nuchal fold thickness was prospectively measured in 258 women undergoing routine ultrasonography at 15 to 21 completed weeks of gestation. Patients with fetal structural or chromosomal anomalies were excluded. At the time of examination the position of the fetal head was noted as being extended or flexed on the basis of the angle between the spine and the base of the skull. Gestational age was based on menstrual dates or ultrasonographic biometric parameters. Data were tested for normality. Mann-Whitney U test and analysis of covariance were used (significance was considered to be P < .05). Data are presented as median and range. Results: A total of 258 fetuses were examined with 167 (65%) in the flexed and 91 (35%) in the extended neck position. Gestational age was not significantly different between the flexed and extended groups (median, 19.1 weeks; range, 15.5-21.6 weeks; vs median, 19.1 weeks; range, 15.6-22 weeks; P = .23). Nuchal fold thickness was significantly lower in the flexed group than in the extended group (median, 3.5 mm; range, 1.3-6.2 mm; vs median, 3.9 mm; range, 2.2-4.9 mm; P = .0097). Nuchal fold thickness increased significantly with gestational age in both groups. The difference in nuchal fold thickness between the 2 groups persisted even after the increase in nuchal fold thickness was adjusted for with gestational age (P = .002, analysis of covariance). The difference between the 2 groups was higher at earlier gestations. Conclusion: Nuchal fold thickness is affected by gestational age and fetal neck position. Correction for these variables may improve the accuracy of nuchal fold thickness measurements in screening for fetal chromosomal anomalies. (Am J Obstet Gynecol 2000;183:995-7.)

Automatically recommending healthy living programs to patients with chronic diseases through hybrid content-based and collaborative filtering

In this research, we develop a hybrid recommendation system recommendation system for healthy living programs to patients with chronic diseases. Our experiments indicate that our model compared favorably against other real-world recommendation applications in terms of accuracy. We also demonstrated that the proposed hybrid algorithm performed better than traditional CF in terms of error rate, precision and recall.
The Fate of Fuel Nitrogen in Coal-Fired Spreader Stokers

Abstract Abstract-Coal-fired spreader-stoker boilers are recognized as significant stationary sources of nitrogen oxide (NOx) emissions. Abatement of NOx emissions from spreader stokers has received relatively little research attention. The purpo se of this investigation was to assess the role of first-stage stoichiometry and local thermal environment in the fate of fuel nitrogen. The research was specifically concerned with identifying nitrogenous species evolution and reaction in the fuel-bed burning regime. The approach was experimental, utilizing a fixed-bed furnace configured to simulate the bed-phase combustion environment of coal-fired spreader stokers. Large coal particles sized from 6 through 32mm were fed continuously onto a fixed retort forming a relatively thin (lO to 15em) fuel bed. First-stage stoichiometry was the primary combustion parameter influencing NO formation. Substantial reductions in exhaust NO emissions were achieved under staged combustion conditions. In-flame measurements indic...
Shelf detection via vanishing point and radial projection

Retailers need to monitor products on store shelves in order to maintain adequate stocking and in many cases to comply with a placement arrangement defined by a planogram. It is possible that such inspections be performed automatically or semi-automatically using computer vision techniques. Towards this goal, we propose an algorithm to detect shelves from images captured with a handheld digital camera. First, we identify the vanishing point and the associated line segments corresponding to the shelves. Second, we divide the image into equal-angle wedges centered at the vanishing point and project the associated line segments into the wedges. Finally, we identify shelves by analyzing the projections.
Formation of gap and tight junctions between reaggregated blastomeres of the killifish, Fundulus

Blastomeres from eggs of the killifish, Fundulus, were mechanically dissociated and reaggregated by pelleting in a simple saline solution. Formation of gap and tight junctions was followed by electron microscopy of freeze- fracture replicas. Five to eight min after pelleting, neither new nor old junctions were observed. After 10–15 min, small gap junctions were found, but these were not associated with distinct formation plaques. Larger gap junctions were observed after 45 min, and the images were consistent with growth by accretion of intramembrane particles. In aggregates, after 20 min or more, tight junctions were much more commonly found than in intact blastulae, and it seemed likely that they were being formed by cells that were not doing so in the intact embryo. Initial stages consisted of short strands that appeared to grow in length. Also, more elaborate junctions were seen than occur in situ. Particle-free membrane often occurred near incomplete junctions, and large junctions like those in situ separated particle-rich from particle-free membrane. In this system, the formation of both gap and tight junctions occurs with shorter latency, and is more precisely timed, than heretofore described.
Being and power: Heidegger and Foucault

Abstract At the heart of Heidegger's thought is the notion of being, and the same can be said of power in the works of Foucault. And, just as Heidegger offers a history of being, culminating in the technological understanding of being, in order to help us understand and overcome our current way of dealing with things as objects, Foucault analyses several regimes of power, culminating in modern bio‐power, in order to help us free ourselves from understanding ourselves as subjects. I argue that these parallels arise because Foucault's notion of power denotes the social aspect of what Heidegger calls the clearing. That is, while Heidegger is concerned with the coordination of everyday practices that makes possible the disclosure of all types of entities, Foucault is concerned with the practices that determine what, at any given time, it makes sense for people to do. Heidegger further claims that, since the Greeks, the clearing has been misunderstood. He calls this misunderstanding, which sees intelligibility...
