AbstractALn4(MoO4)7 (A = Ba, Sr, Ca, Ln = La, Pr, Nd, Sm) ceramics are prepared by solid state ceramic route and the structural properties have been studied using powder X‐ray diffraction and laser Raman spectroscopy. All the ceramics under study are phase pure except BaLn4(MoO4)7 (Ln = Pr, Nd, Sm). Scanning electron micrographs of the sintered ceramics show closely packed microstructure with phase homogeneity. BaLa4(MoO4)7 ceramic has a maximum density of 4.5 g/cm3 at 710°C together with ԑr = 11.8, Qu x f = 39 300 GHz, and τf = −68 ppm/oC. SrLa4(MoO4)7 ceramic exhibited a maximum density of 4.4 g/cm3, ԑr = 11.7, Qu x f = 44 200 GHz, and τf = −83 ppm/°C at 740°C whereas CaLa4(MoO4)7 ceramic possess a maximum density of 4.2 g/cm3, ԑr = 11.4, Qu x f = 30 200 GHz and τf = −90 ppm/oC at 750°C at microwave frequencies. The chemical compatibility of the BaLa4(MoO4)7, SrLa4(MoO4)7 and CaLa4(MoO4)7 ceramics with silver electrode have been studied using powder X‐ray diffraction of the co‐fired samples and is further examined with energy dispersive X‐ray spectroscopy.
Effect of codoping Ce3+ on the luminescence properties of Sr9Mg1.5(PO4)7:Eu2+ orange–yellow phosphor
Authors: Wanjun Tang , Fen Zhang 
Published: January 2019

AbstractSr9Mg1.5(PO4)7:Eu2+ has recently been reported as a promising blue light‐excited orange–yellow phosphor that can be used in white LED device. Here, Ce3+‐codoping is found to be an effective strategy to improve the luminescence performance of Sr9Mg1.5(PO4)7:Eu2+ phosphor. The coexistence of Eu2+ and Eu3+ ions has been verified via photoluminescence spectral analysis. The reduction of Eu3+ to Eu2+ in Sr9Mg1.5(PO4)7 lattice cannot be completed in a reducing atmosphere, but can be promoted through codoping with Ce3+ ions to a great extent, which finally increase the effective concentration of Eu2+ in the crystal lattice. The Eu3+−Eu2+ reduction mechanism is analyzed using a charge compensation model. This work not only achieves enhanced luminescence of the Sr9Mg1.5(PO4)7:Eu2+ phosphor by codoping with Ce3+ ions, but also provides new insights into the design of Ce3+/Eu2+ codoped luminescent materials.

AbstractTumour necrosis factor‐α‐induced protein 8‐like 2 (TIPE2) is a tumour suppressor in many types of cancer. However, the mechanism of action of TIPE2 on the growth of rectal adenocarcinoma is unknown. Our results showed that the expression levels of TIPE2 in human rectal adenocarcinoma tissues were higher than those in adjacent non‐tumour tissues. Overexpression of TIPE2 reduced the proliferation, migration, and invasion of human rectal adenocarcinoma cells and down‐regulation of TIPE2 showed reverse effects. TIPE2 overexpression increased apoptosis through down‐regulating the expression levels of Wnt3a, phospho (p)‐β‐Catenin, and p‐glycogen synthase kinase‐3β in rectal adenocarcinoma cells, however, TIPE2 knockdown exhibited reverse trends. TIPE2 overexpression decreased autophagy by reducing the expression levels of p‐Smad2, p‐Smad3, and transforming growth factor‐beta (TGF‐β) in rectal adenocarcinoma cells, however, TIPE2 knockdown showed opposite effects. Furthermore, TIPE2 overexpression reduced the growth of xenografted human rectal adenocarcinoma, whereas TIPE2 knockdown promoted the growth of rectal adenocarcinoma tumours by modulating angiogenesis. In conclusion, TIPE2 could regulate the proliferation, migration, and invasion of human rectal adenocarcinoma cells through Wnt/β‐Catenin and TGF‐β/Smad2/3 signalling pathways. TIPE2 is a potential therapeutic target for the treatment of rectal adenocarcinoma.

AbstractObjectivePeriodontal disease is a possible contributing factor to preterm delivery. The aim of this study was to compare the periodontal status of women with preterm prelabour rupture of membranes (PPROM) and women with uncomplicated singleton pregnancies.Patients and MethodsSeventy‐eight women with PPROM at gestational ages between 24 + 0 and 36 + 6 weeks and 77 healthy women with uncomplicated pregnancies, matched for gestational age at sampling without preterm birth, were included in this study. All women underwent evaluation of periodontal and oral hygiene status.ResultsWomen with PPROM had higher gingival and plaque indexes in crude analysis (gingival index: median 0.80 versus 0.20; p < 0.0001; plaque index: median 0.80 versus 0.10; p < 0.0001), even after adjustment for smoking status (p < 0.0001 and p < 0.0001). Mean clinical attachment loss (CAL) and probing pocket depth (PPD) values were higher in women with PPROM in the crude analysis (CAL: median 2.3 mm versus 1.8 mm; p < 0.0001; PPD: median 2.3 mm versus 1.8; p < 0.0001), as well as after adjustment for smoking status (p < 0.0001 and p < 0.0001).ConclusionsPregnant women with PPROM residing in central Europe had worse periodontal status than women with uncomplicated pregnancies.
FINANCIAL EXPERTS ON THE BOARD: DOES IT MATTER FOR THE PROFITABILITY AND RISK OF THE U.K. BANKING INDUSTRY?
Authors: Apergis Nicholas 
Published: January 2019

AbstractIn this article, I explore the relation among board‐level financial expertise, profitability, and risk with panel data from the U.K. banking industry. The empirical findings document that collectively, financial experts have a positive influence on the performance of banks; contribute to higher risks, especially for large banks; and improve the stock performance of banks. Moreover, the results highlight that board‐level qualified accountants have no statistical effect on profitability, whereas financial and banking professors, as well as financial experts from other industries, have a positive effect. Such findings imply that these two groups of professional financial experts may more easily adopt group‐level profit enhancements. Robustness checks confirm the results for all types of banking institutions, except those with strong real estate portfolios. Finally, certain commercial and/or policy implications of the results are reported.
COME ON IN, THE WATER'S FINE! AN EXPERIMENTAL EXAMINATION OF HYBRID IPO AUCTIONS WITH A PUBLIC POOL
Authors: Schnitzlein Charles R. , Shao Minjie , Sherman Ann E. 
Published: January 2019

AbstractWe offer experimental and theoretical evidence that auction methods for initial public offerings (IPOs) in the United States may be improved through hybrids that include a separate retail tranche or “public pool.” The multi‐unit uniform price auctions in our laboratory experiments incorporate key IPO features including endogenous entry, costly information acquisition, and differing capacity constraints. As predicted, hybrids increase proceeds and reduce price volatility, price error, and the incentive for small bidders to free ride. Underpricing occurs in both treatments but is attenuated with the public pool. Our results imply that both IPO auctions and equity crowdfunding/crowdinvesting should include separate, non‐price‐setting tranches for the general public.
Credit Crunches from Occasionally Binding Bank Borrowing Constraints
Authors: HOLDEN TOM D. , LEVINE PAUL , SWARBRICK JONATHAN M. 
Published: January 2019

AbstractWe present a model in which banks and other financial intermediaries face both occasionally binding borrowing constraints, and costs of equity issuance. Near the steady state, these intermediaries can raise equity finance at no cost through retained earnings. However, even moderately large shocks cause their borrowing constraints to bind, leading to contractions in credit offered to firms, and requiring the intermediaries to raise further funds by paying the cost to issue equity. This leads to the occasional sharp increases in interest spreads and the countercyclical, positively skewed equity issuance that are characteristics of the credit crunches observed in the data.
New Mexico Nurse‐Midwives’ Controlled Substance Prescribing and Monitoring Practices

Published: January 2019

IntroductionNew Mexico, a state with a high incidence of opioid overdose deaths, requires certified nurse‐midwives (CNMs) who prescribe controlled substances to use the statewide Prescription Monitoring Program (PMP). This study examined how frequently CNMs who practice in New Mexico and prescribe controlled substances use the PMP and the purposes for which they use it.MethodsAll CNMs licensed in New Mexico (N = 210) were sent a link to an anonymous online survey. CNM demographics, practice characteristics, and controlled substance prescribing practices were examined.ResultsApproximately 40% of CNMs licensed in New Mexico completed the survey (N = 83), 77% of whom (64/83) were providing direct clinical care services. Nearly all who were engaged in clinical care had a US Drug Enforcement Administration registration number and were registered in the PMP (97%; 62/64). Approximately 90% of those respondents (56/62) reported prescribing controlled substances. Approximately 10% (6/62) never logged into the PMP, 40% (25/62) never ran a self‐report, and nearly 30% (18/62) reported never checking the PMP for patient alerts. Among those who reported prescribing controlled substances, the percentages who never logged in, never ran a self‐report, and never checked for patient alerts were 7% (4/56), 37% (21/56), and 27% (15/56), respectively. Nearly half of those prescribing controlled substances (26/56) did so monthly or more often, but with respect to their own prescribing, approximately one‐third of them (9/26) checked the PMP less frequently than every 6 months.DiscussionMost CNMs in New Mexico are authorized to prescribe controlled substances, but the frequency of prescribing varies, and some CNMs may not be making optimal use of the state PMP for self‐reports, for patient alerts, or prior to prescribing a controlled substance. Additional education pertaining to the PMP is needed, as are best practice recommendations for monitoring CNMs’ controlled substance prescribing.

Published: January 2019

AbstractPurposeTo identify associations between implant failure and selective serotonin reuptake inhibitor (SSRI) medication use in a cohort of consecutive patients receiving dental implants during a 20‐year period.Materials and MethodsA retrospective review was conducted of all patients who received at least 1 dental implant from January 1, 1995, through December 31, 2014, assessing their history of SSRI use, active SSRI use, and SSRI use during follow‐up with implant failure. Cox proportional hazards regression models assessed associations between demographic characteristics and SSRI use with implant failure, and outcomes were summarized with hazard ratios (HRs) and 95% confidence intervals (CIs). Follow‐up SSRI use was analyzed with time‐dependent covariates.ResultsDuring the study period, 5456 patients received their first implant (median age, 53 years). The median duration of follow‐up was 5.3 years (interquartile range, 2.3‐10.2 years) for the 4927 patients who did not have implant failure. For the 529 patients who had implant failure, it occurred at a median of 0.5 years. After adjusting for age, sex, and era of implant, history of use of the SSRI sertraline was associated with an increased risk of implant failure among all patients (hazard ratio [HR], 1.60; 95% CI, 1.15‐2.23; p = 0.006) and among the subset of patients with a history of SSRI use (HR, 1.64; 95% CI, 1.07‐2.52; p = 0.02).ConclusionsIn the population reviewed, a history of sertraline use was associated with a 60% greater risk of implant failure; however, active SSRI use at the time of implant placement or during follow‐up was not significantly associated with an increased risk of implant failure.
Using the Big Five Aspect Scales to translate between the HEXACO and Big Five personality models

Published: January 2019

AbstractObjectiveThe extensive use of two diverging personality taxonomies (the Big Five and HEXACO models) in contemporary research creates a need for understanding how traits connect to each other across taxonomies. Previous research has approached this at both a highly general (domain‐) level as well as at a highly specific (facet‐) level. The present report is the first to use the intermediate (aspect‐) level of the Big Five Aspect Scales (BFAS) to understand the connections between the two models.MethodWe explored these associations in a meta‐analysis of four samples drawn from three countries (total N = 1,586).ResultsWe observed that each HEXACO domain correlated ≥|0.51| with one or more BFAS aspects. Half of the aspects were more strongly associated with HEXACO facets than with HEXACO domains, sometimes markedly so.ConclusionAlthough many domains, aspects, and facets are similarly represented across the two models, this was not always the case. Researchers seeking to use one model to extend findings built primarily off the other should carefully consider how well represented their traits of interest are in the other assessment. Psychology instructors are encouraged to use the BFAS to illustrate the subtler distinctions between the Big Five and HEXACO models.

Published: January 2019

ABSTRACTBACKGROUNDIn 2016, the United States Department of Agriculture issued a final rule to strengthen local wellness policies (LWPs). As school districts pursue compliance, states can provide critical guidance by leveraging support from intermediary programs such as the Supplemental Nutrition Assistance Program—Education (SNAP‐Ed). After Arizona SNAP‐Ed piloted a statewide model for assessing LWPs, we evaluated that model by exploring local SNAP‐Ed agency experiences with the pilot. Our case study objectives were to determine the model's feasibility and utility from the perspective of local agencies supporting school districts during LWP review and revision.METHODSWe used open‐ended semistructured interviews with the 13 local SNAP‐Ed agencies who engaged in each LWP assessment phase and analyzed data using constant comparative analysis.RESULTSParticipants found the model feasible and useful. Five themes emerged, 3 of which tracked strongly with successful LWP review and revision: local agency staff comprehension, the openness of local agency staff and district/school personnel to the process, and the local agency's engagement of the district/school throughout the process.CONCLUSIONSLeveraging local agency support can be an effective strategy to improving LWPs, given understanding, buy‐in, and staff engagement. Findings can inform agencies seeking to engage intermediaries in LWP assessment and revision.
Substance Use and School Characteristics in Lesbian, Gay, Bisexual, and Heterosexual High School Students
Authors: Fallin‐Bennett Amanda , Goodin Amie 
Published: January 2019

ABSTRACTBACKGROUNDTobacco, alcohol, and illicit drug use among lesbian, gay, and bisexual (LGB) high school students as well as related environment and school‐level risk and protective factors were examined.METHODSData was acquired from the 2015 CDC's Youth Behavior Risk Survey for Kentucky (N = 2577). Prevalence of substance use was calculated for all high school respondents by reported sexual orientation. Multivariate analyses estimated the relationship between school and environmental‐level factors (eg, having an adult to talk to) and tobacco, alcohol, and illicit drug use via logistic regressions. Sexual orientation, gender, age, and race/ethnicity were covariates.RESULTSLGB students used tobacco, alcohol, and illicit drugs more frequently than their heterosexual counterparts. More LGB teens report facing school risk factors (eg, 37% LGB vs 20% heterosexual bullied at school, p ≤ .001; 17% LGB vs 5% heterosexual ever threatened or injured at school, p < .001; 13% LGB vs 7% heterosexual involved in a school fight, p = .001). Adjusting for school related risk factors, having an adult to talk to was associated with a reduced likelihood of daily smoking (adjusted odds ratio [aOR]: 0.43; 95% confidence interval [CI]: 0.26–0.73), past 30‐day alcohol use (aOR: 0.71; 95% CI: 0.50–0.95), and ever marijuana use (aOR: 0.71; 95% CI: 0.50–1.00).CONCLUSIONInnovative strategies are needed to create safe, supportive school environments. These strategies are particularly needed in predominately rural states like Kentucky.
A Paleozoic age for the Tunnunik impact structure
Authors: Lepaulard Camille , Gattacceca Jérôme , Swanson‐Hysell Nicholas , Quesnel Yoann , Demory François , Osinski Gordon R. 
Published: January 2019

AbstractWe report paleomagnetic directions from the target rocks of the Tunnunik impact structure, as well as from lithic impact breccia dikes that formed during the impact event. The target sedimentary rocks have been remagnetized after impact‐related tilting during a reverse polarity interval. Their magnetization is unblocked up to 350 °C. The diabase dikes intruding into these sediments retained their original magnetization which unblocks above 400 °C. The impact breccia records a paleomagnetic direction similar to that of the overprints in the target sedimentary rocks. The comparison of the resulting virtual geomagnetic pole for the Tunnunik impact structure with the apparent polar wander path for Laurentia combined with biostratigraphic constraints from the target sedimentary rocks is most consistent with an impact age in the Late Ordovician or Silurian, around 430–450 Ma, soon after the deposition of the youngest impacted sedimentary rocks. Our results from the overprinted sedimentary rocks and diabase dikes imply that the postimpact temperature of the studied rocks was about 350 °C.
The money creation process: A theoretical and empirical analysis for the United States
Authors: Deleidi Matteo , Levrero Enrico Sergio 
Published: January 2019

AbstractThe aim of this paper is to assess—on both theoretical and empirical grounds—the two main views regarding the money creation process, namely the endogenous and exogenous money approaches. After analysing the main issues and the related empirical literature, we will apply a vector autoregression model and a vector error‐correction model methodology to the United States for the period 1959–2017 to assess the causal relationship between a number of critical variables that are supposed to determine the money supply, that is, the monetary base, bank deposits, bank loans and the nominal level of economic activity. The empirical analysis supports several propositions related to the endogenous money approach. In particular, it shows that for the United States in the years 1959–2017 (a) bank loans determine bank deposits and (b) bank deposits in turn determine the monetary base. Our conclusion is that money supply is mainly determined endogenously by the lending activity of commercial banks and the nominal level of economic activity.
Glycolate from microalgae: an efficient carbon source for biotechnological applications
Authors: Taubert Anja , Jakob Torsten , Wilhelm Christian 
Published: January 2019

SummaryGlycolate is produced in autotrophic cells under high temperatures and Ci‐limitation via oxygenation of ribulose‐1,5‐bisphosphate. In unicellular algae, glycolate is lost via excretion or metabolized via the C2 cycle by consuming reductants, ATP and CO2 emission (photorespiration). Therefore, photorespiration is an inhibitory process for biomass production. However, cells can be manipulated in a way that they become glycolate‐producing ‘cell factories’, when the ratio carboxylation/oxygenation is 2. If under these conditions the C2 cycle is blocked, glycolate excretion becomes the only pathway of photosynthetic carbon flow. The study aims to proof the biotechnological applicability of algal‐based glycolate excretion as a new biotechnological platform. It is shown that cells of Chlamydomonas can be cultivated under specific conditions to establish a constant and long‐term stable glycolate excretion during the light phase. The cultures achieved a high efficiency of 82% of assimilated carbon transferred into glycolate biosynthesis without losses of function in cell vitality. Moreover, the glycolate accumulation in the medium is high enough to be directly used for microbial fermentation but does not show toxic effects to the glycolate‐producing cells.
