Single Parents, Unhappy Parents? Parenthood, Partnership, and the Cultural Normative Context

Although the question of whether parenthood is generally beneficial for well-being is currently being hotly debated in the social sciences, single parents are nearly unanimously assumed to be worse off than their partnered counterparts. The present research questions this finding by demonstrating that whether single parents are actually less happy than partnered parents depends on a country’s cultural norms regarding childbearing practices. Using two large-scale international data sets (the European Values Study [EVS] and the European Social Survey [ESS]) covering altogether 43 countries, we show that only in collectivist countries and countries with a strong two-parent family norm did parenthood negatively affect the life satisfaction and the emotional well-being of single but not partnered (married or cohabiting) individuals. Most notably, the detrimental effect of a country’s social norm of a two-parent family existed even among single parents who did not share this norm themselves.
Instance-based Evaluation of Entailment Rule Acquisition

Obtaining large volumes of inference knowledge, such as entailment rules, has become a major factor in achieving robust semantic processing. While there has been substantial research on learning algorithms for such knowledge, their evaluation methodology has been problematic, hindering further research. We propose a novel evaluation methodology for entailment rules which explicitly addresses their semantic properties and yields satisfactory human agreement levels. The methodology is used to compare two state of the art learning algorithms, exposing critical issues for future progress.
How Do Stamp Duties Affect the Housing Market?

Land transfer taxes are a substantial portion of the cost of moving house in many developed countries. Since stamp duties are endogenous with respect to the house price, we create an instrumental variable that is the stamp duty on a property, given that postcode's starting house price and the national house price trend. In a specification with postcode and year fixed effects, this instrument effectively captures policy changes and nonlinearities in the stamp duty schedule. We find that the impact of an increase in the tax rate is to lower house prices, suggesting that the economic incidence of the tax falls on the seller. We also observe impacts of stamp duty on housing turnover. A 10 per cent increase in stamp duty lowers turnover by 3 per cent in the first year, and by 6 per cent if sustained over a 3 year period.
The transition of a large-scale quality improvement initiative: a bibliometric analysis of the Productive Ward: Releasing Time to Care programme.

AIMS AND OBJECTIVES To examine the literature related to a large-scale quality improvement initiative, the 'Productive Ward: Releasing Time to Care', providing a bibliometric profile that tracks the level of interest and scale of roll-out and adoption, discussing the implications for sustainability. BACKGROUND Productive Ward: Releasing Time to Care (aka Productive Ward) is probably one of the most ambitious quality improvement efforts engaged by the UK-NHS. Politically and financially supported, its main driver was the NHS Institute for Innovation and Improvement. The NHS institute closed in early 2013 leaving a void of resources, knowledge and expertise. UK roll-out of the initiative is well established and has arguably peaked. International interest in the initiative however continues to develop. METHODS A comprehensive literature review was undertaken to identify the literature related to the Productive Ward and its implementation (January 2006-June 2013). A bibliometric analysis examined/reviewed the trends and identified/measured interest, spread and uptake. RESULTS Overall distribution patterns identify a declining trend of interest, with reduced numbers of grey literature and evaluation publications. However, detailed examination of the data shows no reduction in peer-reviewed outputs. There is some evidence that international uptake of the initiative continues to generate publications and create interest. CONCLUSIONS Sustaining this initiative in the UK will require re-energising, a new focus and financing. The transition period created by the closure of its creator may well contribute to further reduced levels of interest and publication outputs in the UK. However, international implementation, evaluation and associated publications could serve to attract professional/academic interest in this well-established, positively reported, quality improvement initiative. RELEVANCE TO CLINICAL PRACTICE This paper provides nurses and ward teams involved in quality improvement programmes with a detailed, current-state, examination and analysis of the Productive Ward literature, highlighting the bibliometric patterns of this large-scale, international, quality improvement programme. It serves to disseminate updated publication information to those in clinical practice who are involved in Productive Ward or a similar quality improvement initiative.
Identification of Relevant Phytochemical Constituents for Characterization and Authentication of Tomatoes by General Linear Model Linked to Automatic Interaction Detection (GLM-AID) and Artificial Neural Network Models (ANNs)

There are a large number of tomato cultivars with a wide range of morphological, chemical, nutritional and sensorial characteristics. Many factors are known to affect the nutrient content of tomato cultivars. A complete understanding of the effect of these factors would require an exhaustive experimental design, multidisciplinary scientific approach and a suitable statistical method. Some multivariate analytical techniques such as Principal Component Analysis (PCA) or Factor Analysis (FA) have been widely applied in order to search for patterns in the behaviour and reduce the dimensionality of a data set by a new set of uncorrelated latent variables. However, in some cases it is not useful to replace the original variables with these latent variables. In this study, Automatic Interaction Detection (AID) algorithm and Artificial Neural Network (ANN) models were applied as alternative to the PCA, AF and other multivariate analytical techniques in order to identify the relevant phytochemical constituents for characterization and authentication of tomatoes. To prove the feasibility of AID algorithm and ANN models to achieve the purpose of this study, both methods were applied on a data set with twenty five chemical parameters analysed on 167 tomato samples from Tenerife (Spain). Each tomato sample was defined by three factors: cultivar, agricultural practice and harvest date. General Linear Model linked to AID (GLM-AID) tree-structured was organized into 3 levels according to the number of factors. p-Coumaric acid was the compound the allowed to distinguish the tomato samples according to the day of harvest. More than one chemical parameter was necessary to distinguish among different agricultural practices and among the tomato cultivars. Several ANN models, with 25 and 10 input variables, for the prediction of cultivar, agricultural practice and harvest date, were developed. Finally, the models with 10 input variables were chosen with fit’s goodness between 44 and 100%. The lowest fits were for the cultivar classification, this low percentage suggests that other kind of chemical parameter should be used to identify tomato cultivars.
The Jasmonate-ZIM-Domain Proteins Interact with the WD-Repeat/bHLH/MYB Complexes to Regulate Jasmonate-Mediated Anthocyanin Accumulation and Trichome Initiation in Arabidopsis thaliana[C][W]

This work examines the molecular mechanism of jasmonate regulation of anthocyanin biosynthesis and trichome initiation. It identifies three bHLH transcription factors and two MYB transcription factors as new targets of JAZ proteins, showing that JAZ proteins attenuate the transcriptional function of WD-repeat/bHLH/MYB complexes to regulate anthocyanin accumulation and trichome. Jasmonates (JAs) mediate plant responses to insect attack, wounding, pathogen infection, stress, and UV damage and regulate plant fertility, anthocyanin accumulation, trichome formation, and many other plant developmental processes. Arabidopsis thaliana Jasmonate ZIM-domain (JAZ) proteins, substrates of the CORONATINE INSENSITIVE1 (COI1)–based SCFCOI1 complex, negatively regulate these plant responses. Little is known about the molecular mechanism for JA regulation of anthocyanin accumulation and trichome initiation. In this study, we revealed that JAZ proteins interact with bHLH (Transparent Testa8, Glabra3 [GL3], and Enhancer of Glabra3 [EGL3]) and R2R3 MYB transcription factors (MYB75 and Glabra1), essential components of WD-repeat/bHLH/MYB transcriptional complexes, to repress JA-regulated anthocyanin accumulation and trichome initiation. Genetic and physiological evidence showed that JA regulates WD-repeat/bHLH/MYB complex-mediated anthocyanin accumulation and trichome initiation in a COI1-dependent manner. Overexpression of the MYB transcription factor MYB75 and bHLH factors (GL3 and EGL3) restored anthocyanin accumulation and trichome initiation in the coi1 mutant, respectively. We speculate that the JA-induced degradation of JAZ proteins abolishes the interactions of JAZ proteins with bHLH and MYB factors, allowing the transcriptional function of WD-repeat/bHLH/MYB complexes, which subsequently activate respective downstream signal cascades to modulate anthocyanin accumulation and trichome initiation.
Comparison of therapy persistence for fixed versus free combination antihypertensives: a retrospective cohort study

Objectives The aim of the study was to compare therapy persistence among patients who started with one of three drug regimens: a monotherapy, or combination therapy either as a fixed combination (ie, ‘single pill’) or as a free combination (ie, two separate antihypertensive agents). Design In a secondary data analysis, we used descriptive statistics and multivariate logistic regression to measure the effect of the three therapy regimens on therapy persistence over 4 years. Setting Prescription data from a large German statutory health insurance provider. Participants All patients who started with a new antihypertensive therapy in 2007 or 2008 (n=8032) were included and followed for 4 years. Primary outcome measure Therapy persistence, defined as receiving a refill prescription no later than within 180 days. Results The persistence rates after 4 years were nearly identical among patients who started with a monotherapy (40.3%) or a fixed combination of two drugs (39.8%). However, significantly more patients who started with free-drug combinations remained therapy persistent (56.4%), resulting in an OR of 2.00 (95% CI 1.6 to 2.5; p<0.0001) for free combinations versus fixed combinations. This trend was observed in all age groups and for men and women. At the end of the study period, the number of different antihypertensive agents was still similar between patients who started with a fixed combination (2.41) and patients who started with a free combination (2.28). Conclusions While single-pill combinations make it easier to take different drugs at once, the risk is high that these several substances are stopped at once. Therapy persistence was significantly better for patients who started with a free-drug combination without taking much fewer different antihypertensive drugs as those with a fixed combination.
An Introduction to the Traditional Fermented Foods and Beverages of Turkey

Fermented foods and beverages, whether of plant or animal origin, play an important role in the diet of people in many parts of the world. Fermented foods not only provide important sources of nutrients but have also great potential in maintaining health and preventing diseases. Lactic acid bacteria and yeasts are the major group of microorganisms associated with traditional fermented foods. Many different types of traditional fermented foods and beverages are produced at household level in Anatolia. These include fermented milks (yoghurt, torba yoghurt, kurut, ayran, kefir, koumiss), cereal-based fermented food (tarhana), and non-alcoholic beverage (boza), fermented fruits, and vegetables (turşu, şalgam, hardaliye), and fermented meat (sucuk). However, there are some differences in the preparation of traditional foods and beverages from region to region. The focus of this article is to describe the traditional fermented foods and beverages of Turkey.
W-Net: A Deep Model for Fully Unsupervised Image Segmentation

While significant attention has been recently focused on designing supervised deep semantic segmentation algorithms for vision tasks, there are many domains in which sufficient supervised pixel-level labels are difficult to obtain. In this paper, we revisit the problem of purely unsupervised image segmentation and propose a novel deep architecture for this problem. We borrow recent ideas from supervised semantic segmentation methods, in particular by concatenating two fully convolutional networks together into an autoencoder--one for encoding and one for decoding. The encoding layer produces a k-way pixelwise prediction, and both the reconstruction error of the autoencoder as well as the normalized cut produced by the encoder are jointly minimized during training. When combined with suitable postprocessing involving conditional random field smoothing and hierarchical segmentation, our resulting algorithm achieves impressive results on the benchmark Berkeley Segmentation Data Set, outperforming a number of competing methods.
General formulation for force distribution in power grasp

A general formulation of the force distribution equations for three-dimensional power grasp is presented. It allows for any number of contacts on the finger surfaces and the palm. The formulation not only includes the active forces and moments applied at the contacts, but also the passive forces resulting from frictional and geometric constraints, such as wedging effects. A grasp matrix is developed for the power grasp case and a new approach is taken to define the hand Jacobian matrix. Contact conditions are modeled to consider both constrained and unconstrained directions for the forces. A stability analysis for power grasp is performed in order to evaluate its stability properties. Due to the inherently stable nature of power grasps, the main objective is not the determination of optimum contact locations, but is the determination of joint torques for optimum force distribution. The stability region is defined and used as a measure to study and compare the different stability aspects of power grasps. Results of stability analysis for power grasps, using the DIGITS Grasping System as a model, are also provided. <<ETX>>
Novel Ti–Zr–Hf–Fe Nanostructured Alloy for Biomedical Applications

The synthesis and characterization of Ti40Zr20Hf20Fe20 (atom %) alloy, in the form of rods (ϕ = 2 mm), prepared by arc-melting, and subsequent Cu mold suction casting, is presented. The microstructure, mechanical and corrosion properties, as well as in vitro biocompatibility of this alloy, are investigated. This material consists of a mixture of several nanocrystalline phases. It exhibits excellent mechanical behavior, dominated by high strength and relatively low Young’s modulus, and also good corrosion resistance, as evidenced by the passive behavior in a wide potential window and the low corrosion current densities values. In terms of biocompatibility, this alloy is not cytotoxic and preosteoblast cells can easily adhere onto its surface and differentiate into osteoblasts.
Study of methanogen communities associated with different rumen protozoal populations

Protozoa-associated methanogens (PAM) are considered one of the most active communities in the rumen methanogenesis. This experiment investigated whether methanogens are sequestrated within rumen protozoa, and structural differences between rumen free-living methanogens and PAM. Rumen protozoa were harvested from totally faunated sheep, and six protozoal fractions (plus free-living microorganisms) were generated by sequential filtration. Holotrich-monofaunated sheep were also used to investigate the holotrich-associated methanogens. Protozoal size determined the number of PAM as big protozoa had 1.7–3.3 times more methanogen DNA than smaller protozoa, but also more endosymbiotic bacteria (2.2- to 3.5-fold times). Thus, similar abundance of methanogens with respect to total bacteria were observed across all protozoal fractions and free-living microorganisms, suggesting that methanogens are not accumulated within rumen protozoa in a greater proportion to that observed in the rumen as a whole. All rumen methanogen communities had similar diversity (22.2 ± 3.4 TRFs). Free-living methanogens composed a conserved community (67% similarity within treatment) in the rumen with similar diversity but different structures than PAM (P < 0.05). On the contrary, PAM constituted a more variable community (48% similarity), which differed between holotrich and total protozoa (P < 0.001). Thus, PAM constitutes a community, which requires further investigation as part of methane mitigation strategies.
Lipopolysaccharide induction of monocyte matrix metalloproteinases is regulated by the tyrosine phosphorylation of cytosolic phospholipase A2

Activation of human monocytes with lipopolysaccharide (LPS) results in the production of matrix metalloproteinases (MMPs) through a prostaglandin E2 (PGE2)‐cAMP‐dependent pathway. In this study, the early signaling events involved in this signal transduction pathway were evaluated. Pretreatment of human peripheral blood monocytes with herbimycin A, a tyrosine kinase inhibitor, or arachidonyl trifluoromethyl ketone (AACOCF3), a specific inhibitor of cytosolic phospholipase A2 (cPLA2) inhibited the induction of PGE2 by LPS. This resulted in the inhibition of protein expression of gelatinase B (MMP‐9) and interstitial collagenase (MMP‐1), two major MMPs secreted by activated monocytes. Addition of arachidonic acid (AA) reversed the inhibitory effect of herbimycin A or AACOCF3 on monocyte MMP production, indicating the importance of tyrosine phosphorylation and the involvement of cPLA2 at an early stage in the signal transduction pathway of MMPs. This finding was further supported by LPS‐induced shift in cPLA2 migration and tyrosine phosphorylation based on immunoblotting and immunoprecipitation studies. These results provide evidence that tyrosine phosphorylation of cPLA2 is one of the initial steps needed for the LPS induced MMP production in human monocytes. J. Leukoc. Biol. 64: 221–227; 1998.
Motivation for emigration, values, wellbeing, and identification among young Russian Jews

We conceptualize motivations to emigrate as expressions of basic motivations in the context of emigration. We propose three theoretically distinct motivations to emigrate: preservation (physical, social, and psychological security), self-development (personal growth in abilities, knowledge, and skills), and materialism (financial wellbeing, wealth). We validate this typology in a sample of 158 potential Jewish emigrants from Russia with confirmatory factor analysis of reasons to emigrate. Each motivation correlates, as hypothesized, with the basic values theorized to underlie it. The relative importance of the motivations and their associations with preferred destination of immigration, group identifications, subjective wellbeing, and economic situation are also largely consistent with hypotheses. We discuss the generalizability of these motivations for understanding emigration in settings around the world. Cet article propose une theorie des motivations a emigrer comme etant des motivations fondamentales.
Pedagogic identities for sale! Segregation and homogenization in Swedish upper secondary school

Abstract The aim of this article is to illustrate how Swedish schools construct different pedagogic identities in the way they marketize themselves. We examine through a Bernsteinian lens how upper secondary schools promote themselves; what identities are being called for by the schools and how these identities are expressed. Moreover, the article intends to study how these identities are reflected in studied school actors and how they can be understood in relation to the labour market. We have analysed texts from various kinds of marketing materials, including websites and prospectuses of the schools. The empirical data also include interviews with various school actors. In addition, we attended and recorded observations at open houses and school fairs. Our findings indicate a strong differentiated market-oriented education system, mediated not only through distinctions in courses and programmes, but also through schools creating highly specific niches and targeting specific students as valuable commodities.
Cosmological information from lensed CMB power spectra

Gravitational lensing distorts the cosmic microwave background (CMB) temperature and polarization fields and encodes valuable information on distances and growth rates at intermediate redshifts into the lensed power spectra. The non-Gaussian band-power covariance induced by the lenses is negligible to l=2000 for all but the B polarization field where it increases the net variance by up to a factor of 10 and favors an observing strategy with 3 times more area than if it were Gaussian. To quantify the cosmological information, we introduce two lensing observables, characterizing nearly all of the information, which simplify the study of non-Gaussian impact, parameter degeneracies, dark energy models, and complementarity with other cosmological probes. Information on the intermediate-redshift parameters rapidly becomes limited by constraints on the cold dark matter density and initial amplitude of fluctuations as observations improve. Extraction of this information requires deep polarization measurements on only 5%-10% of the sky, and can improve Planck lensing constraints by a factor of {approx}2-3 on any one of the parameters with the others fixed. Sensitivity to the curvature and neutrino mass is the highest due to the high-redshift weight of CMB lensing but degeneracies between the parameters must be broken externally.
Differences in Relative Hippocampus Volume and Number of Hippocampus Neurons among Five Corvid Species

The relative size of the avian hippocampus (Hp) has been shown to be related to spatial memory and food storing in two avian families, the parids and corvids. Basil et al. [Brain Behav Evol 1996;47:156–164] examined North American food-storing birds in the corvid family and found that Clark’s nutcrackers had a larger relative Hp than pinyon jays and Western scrub jays. These results correlated with the nutcracker’s better performance on most spatial memory tasks and their strong reliance on stored food in the wild. However, Pravosudov and de Kort [Brain Behav Evol 2006;67:1–9] raised questions about the methodology used in the 1996 study, specifically the use of paraffin as an embedding material and recalculation for shrinkage. Therefore, we measured relative Hp volume using gelatin as the embedding material in four North American species of food-storing corvids (Clark’s nutcrackers, pinyon jays, Western scrub jays and blue jays) and one Eurasian corvid that stores little to no food (azure-winged magpies). Although there was a significant overall effect of species on relative Hp volume among the five species, subsequent tests found only one pairwise difference, blue jays having a larger Hp than the azure-winged magpies. We also examined the relative size of the septum in the five species. Although Shiflett et al. [J Neurobiol 2002;51:215–222] found a difference in relative septum volume amongst three species of parids that correlated with storing food, we did not find significant differences amongst the five species in relative septum. Finally, we calculated the number of neurons in the Hp relative to body mass in the five species and found statistically significant differences, some of which are in accord with the adaptive specialization hypothesis and some are not.
