Two of the most important parameters in any dynamic analysis involving soils are the shear modulus and the damping ratio. Because both shear modulus and damping are strain dependent, curves must be developed to define their variation with shear strain. Fifteen studies (including this one) now provide results from tests on a wide variety of gravels. This paper combines the results of available investigations to develop best-fit relationships between (1) shear wave velocity and equivalent N60 from Becker penetration tests; (2) normalized shear modulus and shear strain; and (3) damping ratio and shear strain. The mean curve for the normalized shear modulus reported for gravelly soil in this study falls near the mean curve reported for sands by Seed and Idriss (1970). The normalized shear modulus curve is dependent on confining pressure, but essentially independent of sample disturbance, relative density, and gradation. The mean damping ratio curve falls toward the lower range of the data reported by Seed and Idriss (1970). The damping ratio curve is dependent on confining pressure but essentially independent of other factors.
Achievement of sustainability in metal life cycles from mining of virgin ore to consumer and industrial devices to end-of-life products requires greatly increased recycling rates and improved processing of metals using conventional and green chemistry technologies. Electronic and other high-tech products containing precious, toxic, and specialty metals usually have short lifetimes and low recycling rates. Products containing these metals generally are incinerated, discarded as waste in landfills, or dismantled in informal recycling using crude and environmentally irresponsible procedures. Low recycling rates of metals coupled with increasing demand for high-tech products containing them necessitate increased mining with attendant environmental, health, energy, water, and carbon-footprint consequences. In this tutorial review, challenges to achieving metal sustainability, including projected use of urban mining, in present high-tech society are presented; health, environmental, and economic incentives for various government, industry, and public stakeholders to improve metal sustainability are discussed; a case for technical improvements, including use of molecular recognition, in selective metal separation technology, especially for metal recovery from dilute feed stocks is given; and global consequences of continuing on the present path are examined.
A new method of femoral fixation for arthroscopic anterior cruciate ligament (ACL) reconstruction using semitendinosus and gracilis (ST/G) tendons is presented. Biomechanical evaluation of the method was performed with pullout tests using animal tissues simulating fixation of ST/G tendons passing around a 2.5-mm pin placed transversely through a femoral tunnel. Clinical assessment of 22 patients was performed according to IKDC, Tegner, Lysholm, isokinetic strength, and KT1000 standards. Fixation strengths ranged from 725 N to 1,600 N for yield and maximal loads to failure for 35-mm to 70-mm cross-pins. Clinical results at mean follow-up of 30 months showed one traumatic failure, IKDC 86% normal or nearly normal, Tegner 6 ave, Lysholm 93 ave, KT1000 86% < 3 mm side-to-side difference on maximal manual evaluation, and isokinetic strength testing of quadriceps 8% deficit with hamstrings 8% deficit. Cross-pin fixation of ST/G tendons may be one of the strongest modes of femoral graft attachment yet devised. Our clinical outcomes in this initial series compare well with previous reports of ACL reconstruction regardless of graft or technique.
In the wake of the end-Permian mass extinction, the Early Triassic (~251.9 to 247 million years ago) is portrayed as an environmentally unstable interval characterized by several biotic crises and heavily depauperate marine benthic ecosystems. We describe a new fossil assemblage-the Paris Biota-from the earliest Spathian (middle Olenekian, ~250.6 million years ago) of the Bear Lake area, southeastern Idaho, USA. This highly diversified assemblage documents a remarkably complex marine ecosystem including at least seven phyla and 20 distinct metazoan orders, along with algae. Most unexpectedly, it combines early Paleozoic and middle Mesozoic taxa previously unknown from the Triassic strata, among which are primitive Cambrian-Ordovician leptomitid sponges (a 200-million year Lazarus taxon) and gladius-bearing coleoid cephalopods, a poorly documented group before the Jurassic (~50 million years after the Early Triassic). Additionally, the crinoid and ophiuroid specimens show derived anatomical characters that were thought to have evolved much later. Unlike previous works that suggested a sluggish postcrisis recovery and a low diversity for the Early Triassic benthic organisms, the unexpected composition of this exceptional assemblage points toward an early and rapid post-Permian diversification for these clades. Overall, it illustrates a phylogenetically diverse, functionally complex, and trophically multileveled marine ecosystem, from primary producers up to top predators and potential scavengers. Hence, the Paris Biota highlights the key evolutionary position of Early Triassic fossil ecosystems in the transition from the Paleozoic to the Modern marine evolutionary fauna at the dawn of the Mesozoic era.
Selective precious and specialty metal separations and recovery using molecular recognition processes are described for commercial mining and recycling operations.
Abstract Based on the quantitative community analysis using species‐level identifications, we track the restoration of benthic ecosystems after the end‐ P ermian mass extinction throughout the L ower T riassic of the western USA . New data on the palaeoecology of the T haynes G roup and S inbad F ormation are provided, which fill a gap between the recently studied palaeoecology of the G riesbachian– D ienerian D inwoody F ormation and the S pathian V irgin F ormation. In the S inbad F ormation and T haynes G roup, 17 species (12 genera) of bivalves, 7 species and genera of gastropods and 2 species and genera of brachiopods are recognized. The new bivalve genus C onfusionella ( P teriidae) is described. A comprehensive review of the whole L ower T riassic succession of benthic ecosystems of the western USA indicates that mid‐ and inner shelf environments show incipient recovery signals around the G riesbachian– D ienerian transition, during the S mithian and, most profound, during the early S pathian. Ecological data from youngest strata of the D inwoody F ormation as well as stratigraphic ranges of species suggest that the late D ienerian was likely a time interval of environmental stress for benthic ecosystems. Despite some evidence for short‐term environmental disturbances (e.g. shift of dominant taxa, transient drop in alpha‐diversity) during the S mithian– S pathian transition, benthic ecosystems did not show any notable taxonomic turnover at that time, in contrast to the major crisis that affected ammonoids and conodonts. Whereas alpha‐diversity of benthic communities generally increased throughout the E arly T riassic, beta‐diversity remained low, which reflects a persistently wide environmental range of benthic species. This observation is in accordance with a recently proposed model that predicts a time lag between increasing within‐habitat diversity (alpha‐diversity) and the onset of taxonomic differentiation between habitats (beta‐diversity) during biotic recoveries from mass extinction events. The observation that beta‐diversity had not significantly increased during the E arly T riassic might also provide an explanation for the comparably sluggish increase in benthic diversity during that time, which has previously been attributed to persistent environmental stress.

= 172,494) and found meaningful relations between follower individual differences (e.g., gender, personality) and ratings of their leaders' behaviors (e.g., transformational leadership, abusive supervision). In Study 2, we conducted a primary study to estimate the extent to which actual leader behaviors or differences in follower perceptions of those behaviors account for these relations. Results suggest that follower perceptions and measurement error explain almost the same or more variance in follower ratings than do actual leader behaviors. In addition, other findings imply that relations between some follower characteristics (e.g., gender, neuroticism) and leadership ratings are likely to be due to perceptual differences associated with these follower characteristics. However, actual leader behaviors also appear to play a role, such that leaders tend to behave differently toward followers who possess high or low levels of certain characteristics (e.g., agreeableness). Taken together, this two-study investigation provides evidence that follower individual differences are related to ratings of leader behaviors and, thus, deserve more attention within leadership theory and research.

OBJECTIVES: To determine the association of antibiotic use with weight outcomes in a large cohort of children. METHODS: Health care data were available from 2009 to 2016 for 35 institutions participating in the National Patient-Centered Clinical Research Network. Participant inclusion required same-day height and weight measurements at 0 to &lt;12, 12 to &lt;30, and 48 to &lt;72 months of age. We assessed the association between any antibiotic use at &lt;24 months of age with BMI z score and overweight or obesity prevalence at 48 to &lt;72 months (5 years) of age, with secondary assessments of antibiotic spectrum and age-period exposures. We included children with and without complex chronic conditions. RESULTS: Among 1 792 849 children with a same-day height and weight measurement at &lt;12 months of age, 362 550 were eligible for the cohort. One-half of children (52%) were boys, 27% were African American, 18% were Hispanic, and 58% received ≥1 antibiotic prescription at &lt;24 months of age. At 5 years, the mean BMI z score was 0.40 (SD 1.19), and 28% of children had overweight or obesity. In adjusted models for children without a complex chronic condition at 5 years, we estimated a higher mean BMI z score by 0.04 (95% confidence interval [CI] 0.03 to 0.05) and higher odds of overweight or obesity (odds ratio 1.05; 95% CI 1.03 to 1.07) associated with obtaining any (versus no) antibiotics at &lt;24 months. CONCLUSIONS: Antibiotic use at &lt;24 months of age was associated with a slightly higher body weight at 5 years of age.
We describe two experiments that examine 3D pathway displays in a head-up location for aircraft landing and taxi. We address both guidance performance and pilot strategies in dividing, focusing, and allocating attention between flight path information and event monitoring. In Experiment 1 the 3D pathway head-up display (HUD) was compared with a conventional 2D HUD. The former was found to produce better guidance, with few costs to event detection. Some evidence was provided that attentional tunneling of the pathway HUD inhibits the detection of unexpected traffic events. In Experiment 2, the pathway display was compared in a head-up versus a head-down location. Excellent guidance was achieved in both locations. A slight HUD cost for vertical tracking in the air was offset by a HUD benefit for event detection and for lateral tracking during taxi (i.e., on the ground). The results of both experiments are interpreted within the framework of object- and space-based theories of visual attention and point to the conclusion that pathway HUDs combine the independent advantages of pathways and HUDs, particularly during ground operations. Actual or potential applications include understanding the costs and benefits of positioning a 3D pathway display in a head-up location.
Noni juice is a globally popular health beverage originating in the tropics. Traditional Tahitian healers believe the noni plant to be useful for a wide range of maladies, and noni juice consumers throughout the world have similar perceptions. Nevertheless, human clinical trials are necessary for a precise understanding of what the health benefits of noni juice are. A review of published human intervention studies suggests that noni juice may provide protection against tobacco smoke-induced DNA damage, blood lipid and homocysteine elevation as well as systemic inflammation. Human intervention studies also indicate that noni juice may improve joint health, increase physical endurance, increase immune activity, inhibit glycation of proteins, aid weight management, help maintain bone health in women, help maintain normal blood pressure, and improve gum health. Further, these studies point to notable antioxidant activity in noni juice, more so than other fruit juices which served as trial placebos. It is this antioxidant effect and its interaction with the immune system and inflammation pathways that may account for many of the observed health benefits of noni juice. However, the existing evidence does have some limitations as far as its general application to noni juice products; all the peer-reviewed human interventions studies to date have involved only one source of French Polynesian noni juice. Geographical factors and variations in processing methods are known to produce commercial noni juice products with divergent phytochemical and nutrient compositions. Therefore, other sources of noni products may have different toxicological and pharmacological profiles.
We have previously shown in two randomized clinical trials that environmental enrichment is capable of ameliorating symptoms of autism spectrum disorder (ASD), and in the present study, we determined whether this therapy could be effective under real-world circumstances. 1,002 children were given daily Sensory Enrichment Therapy, by their parents, using personalized therapy instructions given over the Internet. Parents were asked to assess the symptoms of their child every 2 weeks for up to 7 months. An intention-to-treat analysis showed significant overall gains for a wide range of symptoms in these children, including learning, memory, anxiety, attention span, motor skills, eating, sleeping, sensory processing, self-awareness, communication, social skills, and mood/autism behaviors. The children of compliant caregivers were more likely to experience a significant improvement in their symptoms. The treatment was effective across a wide age range and there was equal progress reported for males and females, for USA and international subjects, for those who paid and those who did not pay for the therapy, and for individuals at all levels of initial symptom severity. Environmental enrichment, delivered via an online system, therefore appears to be an effective, low-cost means of treating the symptoms of ASD.
UNLABELLED: Orofacial clefts are frequently associated with other congenital malformations. Studies vary in incidence and types of anomalies. OBJECTIVE: To evaluate associated malformations in orofacial cleft patients at a major research hospital. STUDY DESIGN: Medical records of 1127 patients, in the Cleft Palate/Craniofacial Clinic, Boys Town National Research Hospital, from January 1980 through February 2000 were reviewed. Patients were divided into two categories: 1) cleft palate only (CP), and 2) cleft lip, with or without cleft palate (CL +/- P). Further categorization included location and type, if any, of other congenital malformations. RESULTS: 47.2% of patients had CP and 52.8% had CL +/- P. 32.2% of all cleft patients had associated congenital malformations. The orofacial region was the most common site, followed by cardiovascular central nervous, and skeletal systems. Congenital malformations were more common in CP (38.7%), than CL +/- P (26.4%). Of malformations diagnosed, 63.1% were chromosomal/syndromic anomalies while 36.9% were non-chromosomal/syndromic. CONCLUSIONS: Recognition of the spectrum of congenital malformations, associated with orofacial clefting, is essential for further diagnostic testing and in some cases genetic counseling.
Intensive sampling of the lower portion of the Thaynes and Moenkopi Groups (Lower Triassic) at separate localities within the Confusion Range, Pahvant Range, Mineral Mountains, Star Range, Kanarraville, Cedar City, Torrey and San Rafael Swell areas (mainly central and southern Utah, USA) leads to the recognition of a new key regional Smithian ammonoid succession. The new biostratigraphical sequence, which is more precise than the long-recognized Meekoceras gracilitatis and Anasibirites kingianus Zones, comprises twelve subdivisions, thus resulting in a sequence with much higher resolution that can be correlated not only with other western USA sites, but also with major worldwide localities as well. Middle and late Smithian faunas contain many taxa with wide geographic distribution, thus enabling long-distance correlation with faunal successions from other regions (e.g., British Columbia, Canadian Arctic, South China, Spiti and Oman). New assemblages from the lowermost beds are the least diversified and poorest preserved; they represent the earliest early/middle Smithian ammonoid faunas reported from the western North American basin. They highlight (a) the sudden Smithian advancement of the marine transgression within this epicontinental sea, (b) that this event is diachronous, and (c) that the paleotopography of the basin most likely was highly irregular. The newly obtained ammonoid succession also allows us to date and follow the transgression from the northern and central part of the basin to the southwesternmost and southeasternmost parts, which were reached during the late Smithian (Anasibirites kingianus beds). In addition, we briefly discuss the now-limited previous regional biozonation in the light of these new results. One new genus (Minersvillites) and nine new species (Kashmirites utahensis, Kashmirites confusionensis, Kashmirites stepheni, ?Xiaoqiaoceras americanum, Minersvillites farai, Inyoites beaverensis, Meekoceras olivieri, Meekoceras millardense, Vercherites undulatus) are also described.
Background Medical students have historically perceived a lack of training in clinical nutrition. Rapid advances in medical science have compelled significant changes in medical education pedagogy. It is unclear what effect this has had on student's perceptions. Objective To assess interns' perception of clinical nutrition education during medical school. Design A cross-sectional survey of medical, surgical, and obstetric interns from 6 academic hospitals across the United States during the middle of their first year in November of 2010 (n = 289). Bivariate analysis and logistic regression was used to describe interns' perceptions and evaluate for factors that determined these perceptions. Results A total of 122 interns responded to the survey, for a response rate of 42%. These interns represented 72 different medical schools. Only 29% of interns reported they had been sufficiently trained in nutrition. On average, interns who reported being prepared reported a mean of 4 ± 3.4 weeks of training during medical school, while unprepared interns reported a mean of 2 ± 2.6 weeks of training (P = .02). Interns with prior graduate training in nutrition (n = 18) almost exclusively reported that medical school training was insufficient (94%, P = .02). After adjusting for age, gender, internship, undergraduate training, and being a foreign graduate, only the number of weeks of training remained significantly associated with perceived preparation (P = .03). Conclusion Most interns in medicine, surgery, and obstetrics feel unprepared to handle cases requiring knowledge of clinical nutrition. Interns feel that medical school is not adequately preparing them for the needs of clinical practice.
The revitalization of cultural burning is a priority for many Native American tribes and for agencies and organizations that recognize the cultural and ecological importance of this practice. Traditional fire practitioners are working to resist the impact of settler colonialism and reestablish cultural burning to promote traditional foods and materials, exercise their sovereignty in land management, and strengthen their communities’ cultural, physical and emotional wellbeing. Despite broad support for cultural burning, the needs of practitioners are often poorly understood by non-Native people, limiting the potential for productive cross-cultural partnerships and programs and services that serve Indigenous nations and communities. This article describes lessons learned from two Indigenous Fire Workshops that brought together cultural fire practitioners, researchers, agency and NGO representatives and members of the public to learn about the use and benefits of cultural burning in California.MANAGEMENT IMPLICATIONSThrough a community-based research project, we explore the practice of Native American cultural burning in two communities in California, its tangible and intangible benefits, and how it differs from non-Indigenous fire practices.We highlight specific cultural elements that are fundamental to these practices but are sometimes misunderstood by non-Native people.We describe the unique needs and challenges faced by practitioners and ways that different entities can support practitioners seeking to revitalize the use of cultural burning.
(1) Purpose: Previous studies investigated the positive relationship between professional identity and career satisfaction in teachers, but the underlying reasons were not explored. Therefore, the present study explores the mediating effects of two variables, namely, psychological empowerment and work engagement on the relationship between professional identity and career satisfaction. (2) Method: The present study used the professional identity scale, psychological empowerment scale, Utrecht Work Engagement scale and career satisfaction scale to investigate 2104 teachers (Mage = 39.50 years, SD = 8.74) in a province in China. The demographic variables (e.g., gender, age, teaching age) were controlled as covariates to conduct conservative predictions. (3) Result: (a) professional identity is positively related to career satisfaction; (b) psychological empowerment and career satisfaction play parallel mediator roles between professional identity and career satisfaction; (c) psychological empowerment and career satisfaction play serial mediator roles between professional identity and career satisfaction. (4) Limitations: Data were collected by participant self-report. This method may lead to recall bias. Further, we adopted a cross-sectional rather than experimental or longitudinal design, thus precluding causal conclusions. Lastly, it would be useful to validate our findings with a national sample. (5) Conclusions: The present study indicates that the relationship between professional identity is positively associated with teacher career satisfaction. More importantly, professional identity can indirectly make an impact on teacher career satisfaction through the single mediating effects of psychological empowerment and work engagement, and the chain mediating effect, by improving the level of psychological empowerment, and thereby increasing work engagement.
Objective Accumulation of advanced glycation end products (AGEs) occurs during normal aging but markedly accelerates in people with diabetes. AGEs may play a role in various age-related disorders. Several studies have demonstrated that skin autofluorescence (SAF) reflects accumulated tissue levels of AGEs. However, very few studies have investigated SAF in the general population. The purpose of the present study was to more thoroughly evaluate the potential association among SAF, chronological age, and lifestyle habits in the general population. Methods A large cross-sectional survey of 10,946 Japanese volunteers aged 20 to 79 years was conducted. Volunteers completed a self-administered questionnaire and underwent SAF measurement on their dominant forearms. The associations of SAF with age and lifestyle habits were analyzed using a multiple stepwise regression analysis. Results Age was independently correlated with SAF. Lifestyle habits such as physical activity, nonsmoking, adequate sleep, low mental stress level, eating breakfast, and abstaining from sugary food were each independently associated with lower SAF. Conclusions SAF was associated with age and healthy lifestyle habits in this general Japanese population. The present study suggests that SAF measurement is a convenient tool for evaluating habitual lifestyle behaviors and may have potential for preventative health education.
OBJECTIVE: To identify risk factors such as signalment, previous competition miles completed, ride characteristics, and physical examination variables associated with the elimination of horses during endurance competitions. DESIGN: Retrospective observational study. SAMPLE: Veterinary records for 3,493 endurance horse competition starts. PROCEDURES: Records were requested of all sanctioned 2007 endurance horse competitions in the United States. Only rides that provided data from all horses were included. The horse's signalment, previous endurance competition record, specific ride characteristics, weight division (ie, based on rider's weight with tack), and physical examination variables throughout the ride were included for analysis. Examination variables were separated into abnormalities occurring prior to the start of the ride, during the first half of the ride, and during the second half of the ride. Multivariate logistic regression was used to identify risk factors for overall elimination and elimination subcategories (lameness and metabolic). RESULTS: Specific breeds, the heavyweight division, and distance of the ride were all associated with an increased risk of elimination. A variety of examination variables prior to the start of the ride and during the ride were associated with elimination and included heart rate, cardiac recovery index, and abnormal gastrointestinal sounds. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that specific risk factors were associated with elimination of horses from endurance competitions. These factors may be used to help identify horses at higher risk for elimination and prevent morbidity associated with competition.
Abstract The Lower Triassic Mineral Mountains area (Utah, USA ) preserves diversified Smithian and Spathian reefs and bioaccumulations that contain fenestral‐microbialites and various benthic and pelagic organisms. Ecological and environmental changes during the Early Triassic are commonly assumed to be associated with numerous perturbations (productivity changes, acidifica‐tion, redox changes, hypercapnia, eustatism and temperature changes) post‐dating the Permian–Triassic mass extinction. New data acquired in the Mineral Mountains sediments provide evidence to decipher the relationships between depositional environments and the growth and distribution of microbial structures. These data also help to understand better the controlling factors acting upon sedimentation and community turnovers through the Smithian–early Spathian. The studied section records a large‐scale depositional sequence during the Dienerian(?)–Spathian interval. During the transgression, depositional environments evolved from a coastal bay with continental deposits to intertidal fenestral–microbial limestones, shallow subtidal marine sponge–microbial reefs to deep subtidal mud‐dominated limestones. Storm‐induced deposits, microbialite–sponge reefs and shallow subtidal deposits indicate the regression. Three microbialite associations occur in ascending order: (i) a red beds microbialite association deposited in low‐energy hypersaline supratidal conditions where microbialites consist of microbial mats and poorly preserved microbially induced sedimentary structure; (ii) a Smithian microbialite association formed in moderate to high‐energy, tidal conditions where microbialites include stromatolites and associated carbonate grains (oncoids, ooids and peloids); and (iii) a Spathian microbialite association developed in low‐energy offshore conditions that is preserved as multiple decimetre thick isolated domes and coalescent domes. Data indicate that the morphologies of the three microbialite associations are controlled primarily by accommodation, hydrodynamics, bathymetry and grain supply. This study suggests that microbial constructions are controlled by changes between trapping and binding versus precipitation processes in variable hydrodynamic conditions. Due to the presence of numerous metazoans associated with microbialites throughout the Smithian increase in accommodation and Spathian decrease in accommodation, the commonly assumed anachronistic character of the Early Triassic microbialites and the traditional view of prolonged deleterious conditions during the Early Triassic time interval is questioned.
