Objective: Operative mortality after open-heart interventions in the octogenarian population is relatively well known. Less has been reported on the medium term survival and quality of life of this growing subgroup of patients. Methods: One hundred and eighty-three consecutive patients aged between 80 and 84 years when they underwent open-heart surgery between January 1995 and June 2000 were retrospectively analysed. The patients were followed up for 36 months as regards survival and compared, after matching for age and gender, to survival in the general Swedish population. The health-related quality of life (HRQOL) of surviving patients was assessed in February 2001 using the SWED-QUAL questionnaire. After matching for differences by age and gender, survival results were compared to Swedish national survival data, and functioning and well-being to the corresponding national norm data. Pre-, intraand post-operative variables were evaluated as predictors for mortality, survival and quality of life. Results: The 30-day mortality rate was 4.6% (n 1⁄4 8). The 36-month survival rate, that was 85.6%, did not differ significantly (P 1⁄4 0:078) from that of a cohort of the Swedish population matched for age and gender. There was no significant difference in survival between male and female patients (P 1⁄4 0:545). Systemic hypertension was the only variable found to be a statistically significant predictor of 36-month mortality (P 1⁄4 0:009). As concerns HRQOL, patients had significantly better physical functioning, satisfaction with physical functioning, relief of pain and emotional well-being (P , 0:01) and similar quality of sleep (P 1⁄4 0:106) as the normal population. Male patients and male normal population responders had similar HRQOL (P . 0:05) while female patients reported significantly better HRQOL than their population counterparts on all five dimensions (P , 0:01). Conclusions: Patients 80–84 years of age may be operated on with acceptable operative mortality and benefit from improved functioning and well-being. Survival and quality of life after open-heart surgery among patients aged 80–84 years of age are comparable to, or even better than in the general Swedish population. q 2002 Published by Elsevier Science B.V.
Expression and Relationship of the Insulin-Like Growth Factor System with Posthatch Growth in the Korean Native Ogol Chicken

Insulin-like growth factors (IGF) act as reg-ulators that modulate proliferation and differentiation of various cells. Also, IGF are involved in metabolism and body growth by regulating the synthesis and degradation of glycogen and proteins in animals. However, the effect of IGF system on body growth in poultry including Korean Native Ogol chickens (KNOC) has not been thor-oughly studied. Therefore, this study was performed to investigate the expressions of IGF system and the relationship of IGF with body growth during posthatch growth in KNOC. Sera and organs were collected at hatch and at 1, 3, 5, and 7 wk. The mRNA expressions of IGF, IGF-I receptor, and IGF binding protein (IGFBP)-2 were quan-titatively analyzed by reverse transcription (RT)-PCR. The IGF concentrations were measured by heterologous
Phase transitional behavior and piezoelectric properties of (Na0.5K0.5)NbO3–LiNbO3 ceramics

Lead-free piezoelectric ceramics (1−x)(Na0.5K0.5)NbO3–xLiNbO3 {[Lix(Na0.5K0.5)1−x]NbO3} (x=0.04–0.20) have been synthesized by an ordinary sintering technique. The materials with perovskite structure is orthorhombic phase at x⩽0.05 and becomes tetragonal phase at x⩾0.07, a phase K3Li2Nb5O15 with tetragonal tungsten bronze structure begins to appear at x=0.08 and becomes dominant with increasing the content of LiNbO3. A morphotropic phase boundary between orthorhombic and tetragonal phases is found in the composition range 0.05<x<0.07. Analogous to Pb(Zr,Ti)O3, the piezoelectric and electromechanical properties are enhanced for compositions near the morphotropic phase boundary. Piezoelectric constant d33 values reach 200–235pC∕N. Electromechanical coefficients of the planar mode and the thickness mode reach 38%–44% and 44%–48%, respectively. The Curie temperatures (TC) of [Lix(Na0.5K0.5)1−x]NbO3 (x=0.04–0.20) are in the range of 452–510°C, at least 100°C higher than that of conventional Pb(Zr,Ti)O3. Our re.
The Television Existence in the Age of on-Demand Video Streaming

Television is a favorite mass media for some people; even watching television has become a mandatory ritual. Indeed, television shows have an impact on viewers. As technology develops and advances, television conditions change. This study aims to examine the current pattern of television use in Karanganyar City, Indonesia, in the era of popularity and increasing use of on-demand video streaming. This research is descriptive quantitative research. The research method used is a questionnaire survey, and the analysis was done using descriptive statistics. The results showed that the audience chose to watch television to seek information and entertainment. However, the Karanganyar audiences are not included in the heavy audience category. Their favorite programs are drama and news. For this reason, television programs must be educational and informative. The television must conduct a thorough evaluation so that other media do not drown out the use of television.
CORRIGENDUM: On the robustness of surface vibrational modes: case studies in the Cd region On the robustness of surface vibrational modes: case studies in the Cd region

Recent studies of the stable Cd isotopes, using inelastic neutron scattering, radioactive decay and nucleon-transfer reactions, have resulted in the need to fundamentally reassess the concept of low-energy vibrational modes in these isotopes. We present a synopsis of the nuclear physics that has led to this situation, followed by the present status of spectroscopy for and against vibrational modes in nuclei neighbouring the Cd isotopes. We continue with some details of the spectroscopic techniques used and examples of the data obtained which lead to the above statements. We provide further perspective with some details of octupole degrees of freedom. We conclude with an outlook of where spectroscopic data are needed to further assess the presence or absence of low-energy vibrations in nuclei; and we provide some reflections on where future theoretical investigations should be directed.
Relationships between ethical decision-making and professional behavior in Iranian nursing students

Ethical decision-making and professional behavior are essential skills in nursing profession, hence educational programs should be designed to enable future nurses to tackle problems related to ethical decision-making. This descriptive, correlational and analytical study aimed at determining the ability of Iranian nursing students to make ethical decisions as well as relationship between such decisions and professional behavior. The present study used census to select 140 freshmen from the School of Nursing and Midwifery of Tabriz University of Medical Sciences, Tabriz, Iran. Data collection tools included a demographic questionnaire, the Nursing Dilemma Test (NDT) comprising two indices of “nurse’s principled thinking” and “practical consideration”, as well as the Nursing Students Professional Behaviors Scale (NSPBS).
Observations of shear flows in high-energy-density plasmas

The research discussed in this dissertation represents work toward the demonstration of experimental designs for creating a Kelvin-Helmholtz (KH) unstable shear layer in a high-energy-density (HED) plasma. Such plasmas are formed by irradiating materials with several kilo-Joules of laser light over a few nanoseconds, and are defined as having an internal pressure greater than one million atmospheres. Similar plasmas exist in laboratory fusion experiments and in the astrophysical environment. The KH instability is a fundamental fluid instability that arises when strong velocity gradients exist at the interface between two fluids. The KH instability is important because it drives the mixing of fluids and initiates the transition to turbulence in the flow. Until now, the evolution of the KH instability has remained relatively unexplored in the HED regime. This dissertation presents the observations and analysis of two novel experiments carried out using two separate laser facilities. The first experiment used 1.4 kJ from the Nike laser to generate a supersonic flow of Al plasma over a low-density, rippled foam surface. The Al flow interacted with the foam and created distinct features that resulted from compressible effects. In this experiment there is little evidence of the KH instability. Nevertheless, this experimental design has perhaps pioneered a new method for generating a supersonic shear flow, which has the potential to produce the KH instability if more laser energy is applied. The second experiment was performed on the Omega laser. In this case the 4.3 kJ of laser energy drove a blast wave along a rippled foam/plastic interface. In response to the vorticity deposited and the shear flow established by the blast wave, the interface rolls up into large vorticies characteristic of the KH instability. The Omega experiment was the first HED experiment to capture the evolution of the KH instability.
School readiness and pre-primary learning experiences of children of refugee backgrounds in Tanzania: the mediating role of family socio-economic status

ABSTRACT School readiness of children from refugee backgrounds is not well documented throughout the sub-Saharan region. While evidence has documented the role of home learning environments on learning, little is known about the role of family socioeconomic status. The study recruited 400 pre-primary children, 100 parents, 16 teachers and 8 school principals from in-settlement areas and self-settled naturalised citizens, urban and rural majority groups in Tanzania. Data were collected by interviews, parents’ questionnaires and Bracken’s Basic Concept Scale-Receptive. Parental education, family assets, parental occupation and involvement were strongly related to children’s preparedness for school. However, while children of naturalised groups were from relatively poor families, their school preparedness was comparable to those from higher SES families. Parental beliefs and expectations played vital roles in influencing differences in children’s school readiness across groups. These findings broaden understanding of various factors that influence children’s learning in contexts with limited educational and family resources.
Efficiency of DNA Barcodes for Identification and Documenting Aquatic Insect Diversity in Rice Fields

– Rapid and accurate identifications are crucial for biodiversity assessment. Yet, traditional methods for species identification have some limitations. In this study, we tested the efficiency of mitochondrial cytochrome c oxidase I barcoding sequences for species identification and documenting diversity of aquatic insects in the rice fields of Thailand. Considerable success rate (80%) for species identification was found among the species of the order Odonata. Unidentifiable specimens of immatures were successfully associated with conspecific adults or by matching with reference sequences in the public DNA barcoding library. However, some specimens were ambiguous, possibly due to incomplete lineage sorting of closely related species or erroneous identification of the sequences in the public database. The technique was less successful for other insect orders because a lack of reference sequences in the DNA barcode library limits the utility of DNA barcoding. The Poisson tree process and Automatic Barcode Gap Discovery species delimitations revealed that the number of species recognized is more than twice that based on morphological identification. Therefore, DNA barcoding has potential for use in species identification and biodiversity assessment of the aquatic insects in the rice field ecosystem.
Modeling laminar sheet flow over rough surfaces

A mathematical model for two‐dimensional laminar flow over a rough surface is developed. Explicit formulae are presented for the height and average and maximum velocities in terms of measurable quantities and a friction factor. The correction factor α, the ratio of the average to maximum velocity, is also discussed and shown to vary significantly from the value on a smooth surface. Predictions for the film height and velocities are presented and compared with previous experiments. Good agreement is obtained between the theory and experiments. The saline technique for measuring velocities is shown to significantly underpredict the fluid velocity. The Manning, Chezy, and Darcy‐Weisbach formulae all overpredict the velocity in the laminar flow regime. It is also shown that there is a relation between the correction factor and the height or inundation ratio, but there is no relation to the Reynolds number in laminar flow.
Corporate diversification and stock price crash risk: Do female directors matters? Evidence from Malaysia

This study examines the relation between corporate diversification and stock price crash risk and whether female directors moderate this relation. Using a sample of Malaysian publicly listed firms based on 2010–2016 data, our study finds diversification mitigates crash risk but only for highly diversified firms. Our study also finds that the mitigating effect of diversification is more pronounced for firms with higher proportion of female directors in the board in which it is aligned with the notion of gender diversity in promoting good corporate governance. Our findings are beneficial to stock investors in managing the “tail risk” in stock prices of conglomerates/diversified firms.

A Comprehensive Analysis of the Myocardial Transcriptome in ZBED6-Knockout Bama Xiang Pigs

The ZBED6 gene is a transcription factor that regulates the expression of IGF2 and affects muscle growth and development. However, its effect on the growth and development of the heart is still unknown. Emerging evidence suggests that long noncoding RNAs (lncRNAs) can regulate genes at the epigenetic, transcriptional, and posttranscriptional levels and play an important role in the development of eukaryotes. To investigate the function of ZBED6 in the cardiac development of pigs, we constructed the expression profiles of mRNAs and lncRNAs in myocardial tissue obtained from Bama Xiang pigs in the ZBED6 knockout group (ZBED6-KO) and the wild-type group (ZBED6-WT). A total of 248 differentially expressed genes (DEGs) and 209 differentially expressed lncRNAs (DELs) were detected, and 105 potential cis target genes of DELs were identified. The functional annotation analysis based on the Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) databases revealed two GO items related to muscle development by the cis target genes of DELs. Moreover, IGF2 was the direct target gene of ZBED6 by ChIP-PCR experiment. Our results explored the mechanism and expression profile of mRNAs and lncRNAs of ZBED6 gene knockout on myocardium tissue development, mining the key candidate genes in that process like IGF2.
Analysis of the effectiveness of landscape protection in the Liancheng National Nature 1 Reserve,

Background The rapid assessment of the effectiveness of landscape protection in nature reserves is of great significance 9 for the scientific formulation of protection and management countermeasures for nature reserves and is also 10 an urgent problem to be solved for the construction and management of nature reserves in China. Using high- 11 resolution remote sensing image data, this study analyzes the landscape dynamics in the Liancheng National 12 Nature Reserve (LNNR) and their driving factors since the reserve’s promotion to the national level in 2005, 13 and proposes a comprehensive evaluation method for the effectiveness of landscape protection in protected 14 areas based on the Landscape Transfer Index (LTI), Protected Landscape Integrity Index (PLII), and Interfered 15 Landscape Sprawl Index (ILSI). nature conservation sites around the world. These the the scope of of human interference in the reserve. This study proposes a comprehensive method for evaluating the landscape conservation effectiveness of PAs based on the LTI, the PLII, and the ILSI. This method has the potential to be applied to the rapid assessment of landscape conservation effectiveness in various types of protected area.
Clauser-Horne inequality for qutrits

In this brief report we show the new Bell-Clauser-Horne inequality for two entangled three dimensional quantum systems (so called qutrits). This inequality is violated by a maximally entangled state of two qutrits observed via symmetric three input and three output port beamsplitter only if the amount of noise in the system equals ${11-6\sqrt3 \over 2}\approx 0.308$. This is in perfect agreement with the previous numerical calculations presented in Kaszlikowski {\it et. al.} Phys. Rev. Lett. {\bf 85}, 4418 (2000).
Dynamic Large Spatial Covariance Matrix Estimation in Application to Semiparametric Model Construction via Variable Clustering: the SCE approach

To better understand the spatial structure of large panels of economic and financial time series and provide a guideline for constructing semiparametric models, this paper first considers estimating a large spatial covariance matrix of the generalized $m$-dependent and $\beta$-mixing time series (with $J$ variables and $T$ observations) by hard thresholding regularization as long as ${{\log J \, \cx^*(\ct)}}/{T} = \Co(1)$ (the former scheme with some time dependence measure $\cx^*(\ct)$) or $\log J /{T} = \Co(1)$ (the latter scheme with some upper bounded mixing coefficient). We quantify the interplay between the estimators' consistency rate and the time dependence level, discuss an intuitive resampling scheme for threshold selection, and also prove a general cross-validation result justifying this. Given a consistently estimated covariance (correlation) matrix, by utilizing its natural links with graphical models and semiparametrics, after "screening" the (explanatory) variables, we implement a novel forward (and backward) label permutation procedure to cluster the "relevant" variables and construct the corresponding semiparametric model, which is further estimated by the groupwise dimension reduction method with sign constraints. We call this the SCE (screen - cluster - estimate) approach for modeling high dimensional data with complex spatial structure. Finally we apply this method to study the spatial structure of large panels of economic and financial time series and find the proper semiparametric structure for estimating the consumer price index (CPI) to illustrate its superiority over the linear models.
Predicting preterm birth through vaginal microbiota, cervical length, and WBC using a machine learning model

An association between the vaginal microbiome and preterm birth has been reported. However, in practice, it is difficult to predict premature birth using the microbiome because the vaginal microbial community varies highly among samples depending on the individual, and the prediction rate is very low. The purpose of this study was to select markers that improve predictive power through machine learning among various vaginal microbiota and develop a prediction algorithm with better predictive power that combines clinical information. As a multicenter case–control study with 150 Korean pregnant women with 54 preterm delivery group and 96 full-term delivery group, cervicovaginal fluid was collected from pregnant women during mid-pregnancy. Their demographic profiles (age, BMI, education level, and PTB history), white blood cell count, and cervical length were recorded, and the microbiome profiles of the cervicovaginal fluid were analyzed. The subjects were randomly divided into a training (n = 101) and a test set (n = 49) in a two-to-one ratio. When training ML models using selected markers, five-fold cross-validation was performed on the training set. A univariate analysis was performed to select markers using seven statistical tests, including the Wilcoxon rank-sum test. Using the selected markers, including Lactobacillus spp. , Gardnerella vaginalis, Ureaplasma parvum, Atopobium vaginae, Prevotella timonensis, and Peptoniphilus grossensis, machine learning models (logistic regression, random forest, extreme gradient boosting, support vector machine, and GUIDE) were used to build prediction models. The test area under the curve of the logistic regression model was 0.72 when it was trained with the 17 selected markers. When analyzed by combining white blood cell count and cervical length with the seven vaginal microbiome markers, the random forest model showed the highest test area under the curve of 0.84. The GUIDE, the single tree model, provided a more reasonable biological interpretation, using the 10 selected markers (A. vaginae, G. vaginalis, Lactobacillus crispatus, Lactobacillus fornicalis, Lactobacillus gasseri, Lactobacillus iners, Lactobacillus jensenii, Peptoniphilus grossensis, P. timonensis, and U. parvum), and the covariates produced a tree with a test area under the curve of 0.77. It was confirmed that the association with preterm birth increased when P. timonensis and U. parvum increased (AUC = 0.77), which could also be explained by the fact that as the number of Peptoniphilus lacrimalis increased, the association with preterm birth was high (AUC = 0.77). Our study demonstrates that several candidate bacteria could be used as potential predictors for preterm birth, and that the predictive rate can be increased through a machine learning model employing a combination of cervical length and white blood cell count information.
Parenting Education for Low-Income Job Seekers: A Mixed-Methods Analysis of the Parenting with Love and Logic Program

Although the principles and strategies outlined in Cline and Fay’s (1990) Parenting with Love and Logic have been the foundation for several parent and educator training curricula over the last 30 years, there has been a dearth of empirical research to evaluate these programs (Fay, 2012). Prior research has documented the impact of cumulative family risk factors on parenting skills and child outcomes (Repetti et al., 2002, 2012), but few studies have examined the impact of parenting education courses within unemployed, low-income families. This study investigates perceived parental efficacy across the four program domains of connection, autonomy, regulation, and parental stress management within a sample (n = 267) of unemployed parents from several counties across a western state. Analyses show consistent retrospective-pre to post improvement across all four domains. Additionally, reported gains did not vary significantly by gender, age, ethnicity, education level, prior divorce, or financial strain. Small group differences were found according to income level, the age of the participants’ oldest child, and dosage (amount of prior relationship education exposure as well as the number of class sessions attended). Qualitative results are included to illustrate further the thoughts and experiences of program participants.
