Partner Characteristics and Perceptions of Responsibility for Housework and Child Care
Authors: Doan Long , Quadlin Natasha 
Published: August 2018

Objective: This study examines how partner characteristics (i.e., relative income, gender, gender expression) causally affect perceptions of responsibility for housework and child care in heterosexual and same‐sex couples.Background: Although past research has frequently investigated how couples divide chores and child‐care tasks, few studies have examined Americans' normative beliefs about the division of household labor. This is an important oversight because partner characteristics are often correlated within individuals (e.g., heterosexual women are disproportionately lower earning), thus blurring how each characteristic causes a partner to be seen as responsible for tasks.Method: The authors conducted a nationally representative survey experiment (N = 1,025). Respondents were randomly assigned to a vignette condition describing either a heterosexual or same‐sex couple. After viewing the vignette, respondents were asked to assign chores and child‐care tasks based on partners' relative income, gender, and gender expression.Results: In same‐sex couples, partners' gender expression had moderate effects on respondents' chore and child‐care assignments. In heterosexual couples, however, the respondents relied overwhelmingly on gender differences to determine who should be doing household tasks. Relative income had little effect across sexual orientation groups, aside from dictating which partner should exit the workforce to become a stay‐at‐home parent.Conclusion: Gender is the primary factor that drives Americans' normative beliefs about housework and child care.

AimInfants born preterm (<37 weeks' gestation) are at risk of poor neurodevelopmental outcomes; hence, many neonatal centres routinely follow up infants using the Bayley Scales of Infant Development (BSID), although the predictive validity of the BSID for children born preterm is questionable. Our objective is to evaluate the predictive capacity of the BSID for behavioural functioning at school age of children born preterm.MethodsChildren (n = 657 children born <33 weeks' gestation) were enrolled at birth from five neonatal centres around Australia. A psychologist assessed child development at 18 months using the BSID‐II. When children were 7 years (corrected age) of age, parents completed the Strengths and Difficulties Questionnaire, the Behavior Rating Inventory of Executive Function and the Conners 3rd Edition Attention Deficit Hyperactivity Disorder Index. We explored associations between BSID‐II at 18 months and behaviour scores at 7 years and examined the interaction effect of the use of an allied health service between the BSID‐II and behaviour assessments.ResultsFor every one‐point increase on the BSID‐II Mental Development Index, behaviour scores decreased by 0.07 points for the Strengths and Difficulties Questionnaire Total Difficulties (95% confidence interval (CI) −0.10, −0.03), 0.12 points for the Behavior Rating Inventory of Executive Function Global Executive Composite (95% CI −0.21, −0.04) and 0.16 points for the Conners 3rd Edition Attention Deficit Hyperactivity Disorder Index (95% CI −0.26, −0.05).ConclusionThe BSID‐II at 18 months was weakly associated with parent‐reported behaviour at 7 years in children born preterm.

Published: August 2018

AbstractSociocognitive theory views learning, including second language acquisition, as the progressive alignment of individuals vis‐à‐vis their ecosocial environments. In this article we first update sociocognitive theory in light of recent evolutionary/ecological research on learning/teaching: (a) Humans are evolutionarily adapted to adapt to myriad environments, placing a premium on adaptive learning, (b) human adaptation is effected substantially through niche construction—engineering environments to make them more adaptive, and then transmitting the results culturally, placing a premium on adaptive teaching, (c) both human learning and teaching are innate/instinctive, and co‐evolved, and (d) there are many kinds of ‘teachers’ in the world. Second, we briefly review 3 approaches to second language acquisition/teaching (SLA/T) vis‐à‐vis sociocognitive theory: van Lier's ecological‐semiotic approach, Schumann's interactional instinct, and conversation analysis. Third, we apply our theoretical perspective exploratorily to videotaped data of a Japanese learner/user of English as a lingua franca who is baking pastries with a Finnish friend. Our analysis includes 5 widely studied ‘units of participation’: activity types, routines, co‐constructed tellings, repetition, and assessments. Analysis suggests that these constitute powerful environmental support structures yielding rich learning opportunities for SLA/T in moment‐to‐moment interaction. Fourth and finally, we discuss our results vis‐à‐vis our theoretical approach. We conclude by suggesting how our expanded view of teaching/learning might broaden SLA/T's ‘pedagogical imagination.’

AbstractBackgroundThe aim of this study was to determine the ability of the Pediatric version of the Eating Assessment Tool‐10 (PEDI‐EAT‐10) to detect aspiration in children with neurological impairments.MethodsTwo hundred and fifty‐four children were included. Swallowing function was imaged with videofluoroscopic swallowing study (VFSS). The penetration and aspiration scale (PAS) was used to determine the penetration and aspiration severity. Parents completed the PEDI‐EAT‐10, which is a 10 item, reliable, and valid dysphagia symptom specific outcome instrument.Key ResultsThe mean age of children was 59.91 ± 55.33 months (min = 18, max = 315), of which 52.8% were male. The mean PEDI‐EAT‐10 of children with airway aspiration (PAS > 5) was 22.32 ± 10.73 (min = 0, max = 40) and the mean PEDI‐EAT‐10 of children who did not have aspiration (PAS < 6) was 12.35 ± 8.64 (min = 0, max = 40). A linear correlation was found between PEDI‐EAT‐10 and PAS scores of children (r = 0.41, P < 0.001). The sensitivity of a PEDI‐EAT‐10 score greater than 12 in predicting aspiration was 77% and the specificity was 54%. A PEDI‐EAT‐10 score greater than 12 has a positive predictive value of 69% and a negative predictive value of 64%.Conclusions and InferencesThe PEDI‐EAT‐10 could be used to detect unsafe airway issues to identify and refer children for further instrumental swallowing evaluation.

Summary

Carotenoids play important roles in many biological processes, such as light harvesting, photoprotection and visual attraction in plants. However, the regulation of carotenoid biosynthesis is still not fully understood.

Here, we demonstrate that SlBBX20, a B‐box (BBX) zinc‐finger transcription factor, is a positive regulator of carotenoid accumulation in tomato (Solanum lycopersicum). Overexpression of SlBBX20 leads to dark green fruits and leaves and higher levels of carotenoids relative to the wild‐type. Interactions between SlBBX20 and DE‐ETIOLATED 1 (SlDET1) lead to the ubiquitination and 26S proteasome‐mediated degradation of SlBBX20. Moreover, deficiencies in the components of the CUL4‐DDB1‐DET1 complex enhanced the stability of the SlBBX20 protein. Thus, we conclude that SlBBX20 is a substrate of the CUL4‐DDB1‐DET1 E3 ligase.

SlBBX20 can activate the expression of PHYTOENE SYNTHASE 1, encoding a key enzyme in carotenoid biosynthesis, by directly binding to a G‐box motif in its promoter, which results in the elevated levels of carotenoids in SlBBX20 overexpression lines.

We identified a key regulator of carotenoid biosynthesis and demonstrated that the stability of SlBBX20 is regulated by ubiquitination. These findings provide us a new target for the genetic improvement of the nutritional quality of tomato fruit.

AbstractOver the last two decades, it has become increasingly apparent that Wnt signaling plays a critical role in development and adult tissue homeostasis in multiple organs and in the pathogenesis of many diseases. In particular, a crucial role for Wnt signaling in bone development and bone tissue homeostasis has been well recognized. Numerous genome‐wide association studies confirmed the importance of Wnt signaling in controlling bone mass. Moreover, ample evidence suggests that Wnt signaling is essential for kidney, intestine, and adipose tissue development and homeostasis. Recent emerging evidence demonstrates that Wnt signaling may play a fundamental role in the aging process of those organs. New discoveries show that bone is not only the major reservoir for calcium and phosphate storage, but also the largest organ with multiple functions, including mineral and energy metabolism. The interactions among bone, kidney, intestine, and adipose tissue are controlled and regulated by several endocrine signals, including FGF23, klotho, sclerostin, osteocalcin, vitamin D, and leptin. Since the aging process is characterized by structural and functional decline in almost all tissues and organs, understanding the Wnt signaling–related interactions among bone, kidney, intestine, and adipose tissue in aging may shed light on the pathogenesis of age‐related diseases.

Authors: Gupta Vishruti , Sharma Pooja 
Published: August 2018

AbstractThis paper attempts to explore the impact of oil prices on stock prices, exchange rates, and inflation rates in the Indian economy for the time period May 1996 to April 2017. This relationship will be investigated for pre‐ and post‐2008 crises, with an aim to explore the linkages between oil prices and stock prices. The financial crisis of 2008 affected the Indian economy through the external sector, while the rise in interest rates owing to pressure on domestic liquidity eventually affected exchange rates. The study concluded that there exists a structural break in the year 2008 and that there is a long‐term relationship between the concerned macroeconomic variables.Finally, the theoretical hypothesis that oil prices affect stock prices has been confirmed by considering India as a case study. The study concluds that there exists a structural break in 2008 crises.

Published: August 2018

AbstractAg3VO4/mpg‐C3N4 (mesoporous graphitic carbon nitride) heterojunction photocatalysts were prepared by anchoring tiny Ag3VO4 particles on the nanosheet of mpg‐C3N4. The prepared Ag3VO4/mpg‐C3N4 heterojunctions were used to remove tetracycline (TC), a kind of antibiotics widely released into the aquatic environment under solar irradiation. Compared with pure mpg‐C3N4 and Ag3VO4, Ag3VO4/mpg‐C3N4 displayed much higher photocatalytic activity (83.2% removal rate within 90 min under visible‐light irradiation). Importantly, no apparent deactivation was observed for Ag3VO4/mpg‐C3N4‐40 after five cycles, inferring a good reusability. As confirmed by photocurrent measurement and photoluminescence spectra, the excellent photocatalytic property of Ag3VO4/mpg‐C3N4 was credit to the electron–hole separation enhancement at the formed heterojunction of two semiconductors. In addition, a possible mechanism and intermediate products for the Ag3VO4/mpg‐C3N4 photocatalysts toward the photodegradation of TC in aqueous solution under artificial sunlight radiation were proposed based on the scavengers trapping test, ESR spectra and a high‐performance liquid chromatography (HPLC) coupled with mass spectrometer (MS) analysis. This investigation provides a low cost, green and easily practical approach to remove the antibiotics in the aquatic environment.
Chiral Inductions in Excited State Reactions: Photodimerization of Alkyl 2‐Naphthoates as a Model

Published: August 2018

AbstractEnantioselectivity in organic transformations continues to be a topic major interest in organic photochemistry. In the last decade, synergistic combination of photocatalysis and organocatalysis has emerged as a powerful strategy to gain enantioselectivity in photochemical reactions, and remarkable achievements have been obtained. In this strategy, the asymmetric induction is provided in ground state. In contrast, in the conventional enantioselective photochemistry, the chiral induction is controlled in electronic excited state, and to achieve high stereoselectivity is still a formidable challenge. Because the reactions of excited states often yield strained products with unique structures in single step that are difficult to form by thermal reactions, the development of new strategies attempted to achieve enantioselectivity in excited state reactions is still highly desired. Since the short excited state lifetime and low activation energy for reaction in excited state leave little room for manipulating the chiral induction, in order to gain enantioselectivity the substrate molecule has to already reside in a chiral environment during the excitation step. Chiral auxiliaries and chiral supramolecular hosts can provide such environments. In this presentation, we summarize the studies employing chiral auxiliary and chiral microreactor approaches to achieve high asymmetric inductions in excited state reactions performed in our laboratory. We chose the photodimerization of alkyl 2‐naphthoates as a reaction model to give deeper insights into the basic factors controlling chiral induction in excited state.
Responses of leaf C:N:P stoichiometry to water supply in the desert shrub Zygophyllum xanthoxylum

Abstract

Based on the elemental composition of major biochemical molecules associated with different biological functions, the ‘growth rate hypothesis’ proposed that organisms with a higher growth rate would be coupled to lower C:N, especially lower C:P and N:P ratios. However, the applicability of the growth rate hypothesis for plants is unclear, especially for shrubs growing under different water supply.

We performed an experiment with eight soil moisture levels (soil water content: 4%, 6%, 8%, 13%, 18%, 23%, 26% and 28%) to evaluate the effects of water availability on leaf C:N:P stoichiometry in the shrub Zygophyllum xanthoxylum.

We found that leaves grew slowly and favored accumulation of P over C and N under both high and low water supply. Thus, leaf C:P and N:P ratios were unimodally related to soil water content, in parallel with individual leaf area and mass. As a result, there were significant positive correlations between leaf C:P and N:P with leaf growth (u).

Our result that slower‐growing leaves had lower C:P and N:P ratios does not support the growth rate hypothesis, which predicted a negative association of N:P ratio with growth rate, but it is consistent with recent theoretical derivations of growth–stoichiometry relations in plants, where N:P ratio is predicted to increase with increasing growth for very low growth rates, suggesting leaf growth limitation by C and N rather than P for drought and water saturation.

Published: August 2018

AbstractWhile previous studies on language processing highlighted several ERP components in relation to specific stages of sound and speech processing, no study has yet combined them to obtain a comprehensive picture of language abilities in a single session. Here, we propose a novel task‐free paradigm aimed at assessing multiple levels of speech processing by combining various speech and nonspeech sounds in an adaptation of a multifeature passive oddball design. We recorded EEG in healthy adult participants, who were presented with these sounds in the absence of sound‐directed attention while being engaged in a primary visual task. This produced a range of responses indexing various levels of sound processing and language comprehension: (a) P1‐N1 complex, indexing obligatory auditory processing; (b) P3‐like dynamics associated with involuntary attention allocation for unusual sounds; (c) enhanced responses for native speech (as opposed to nonnative phonemes) from ∼50 ms from phoneme onset, indicating phonological processing; (d) amplitude advantage for familiar real words as opposed to meaningless pseudowords, indexing automatic lexical access; (e) topographic distribution differences in the cortical activation of action verbs versus concrete nouns, likely linked with the processing of lexical semantics. These multiple indices of speech‐sound processing were acquired in a single attention‐free setup that does not require any task or subject cooperation; subject to future research, the present protocol may potentially be developed into a useful tool for assessing the status of auditory and linguistic functions in uncooperative or unresponsive participants, including a range of clinical or developmental populations.

ContentsWe aimed to study the effects of resveratrol on the morphology, DNA fragmentation, follicular activation and cell proliferation after in vitro culture of ovine ovarian tissue, and to verify if PI3K pathway is involved in resveratrol action in the sheep ovary. Ovaries were collected and divided into fragments. One fragment was fixed for histology (fresh control). The remaining fragments were cultured for 7 days in control medium (α‐MEM+) alone or with resveratrol (2, 10 or 30 µM). After culture, ovarian tissue was destined to morphological analysis. TUNEL and proliferating cell nuclear antigen (PCNA) analyses were performed in the fresh control, α‐MEM+ and 2 µM resveratrol. Inhibition of PI3K activity was performed through pre‐treatment with LY294002. The percentage of normal follicles was similar between α‐MEM+ and 2 µM resveratrol, and higher than those in other resveratrol treatments. An increase in follicular activation was observed in all treatments compared to fresh control. DNA fragmentation decreased in tissues cultured in 2 µM resveratrol compared to α‐MEM+. Moreover, PCNA‐positive cells were higher in 2 µM resveratrol than in α‐MEM+. LY294002 inhibited follicular activation stimulated by α‐MEM+ and 2 µM resveratrol. In conclusion, 2 µM resveratrol promotes primordial follicle activation compared to the fresh control by reducing DNA fragmentation and stimulating granulosa cell proliferation through activation of the PI3K pathway.
Second‐Best Road Taxes in Polycentric Networks with Distorted Labor Markets*
Authors: Tikoudis Ioannis 
Published: August 2018

AbstractThis paper examines the interaction of road taxes with spatially invariant labor taxation in a polycentric network. It derives analytical expressions for the network counterparts of the traditional double‐dividend effects (i.e., Pigouvian, tax‐interaction, and revenue‐recycling effects), and computes them under different policy regimes. The analysis reveals a series of conditions under which a system of cordons around the major nodes of a network might be more efficient than marginal external cost pricing. With a high elasticity of labor supply and limited public transport coverage, it is shown that the Pigouvian tax rule might reduce welfare even when the generated revenue is used to finance labor tax cuts.

PurposeGrounded in the Cognitive Evaluation Theory, the present experiment aimed to compare the relative impact of competence support provided by coaches versus athlete leaders on players’ competence satisfaction, intrinsic motivation, and performance.MethodsWe recruited 18 existing competitive male basketball teams (ie, 126 players) to participate in the experiment. Each team was randomly assigned to one of three conditions: (a) the coach provided competence support (ie, by encouraging, providing positive feedback, and expressing team confidence); (b) the athlete leader provided competence support; or (c) neither the coach, nor the athlete leader provided competence support (ie, control condition).ResultsTeams in which the athlete leader provided competence support reported higher levels of competence satisfaction and intrinsic motivation than teams in the control condition, a difference that did not emerge when the coach provided competence support. Furthermore, teams in which either the coach or the athlete leader supported team members’ competence performed better compared to teams in the control group.ConclusionOur findings highlight the importance of providing competence support to enhance team performance. Given athlete leaders’ unique impact on teammates’ competence satisfaction and motivation, instructing athlete leaders how to provide competence support constitutes an important motivational pathway for coaches to optimize team functioning.
