Authors: Fernández-Molina Milagros , Bravo Castillo Ana , Fernandez-Berrocal Pablo 
Published: February 2019

Preprimary teachers’ emotional adjustment is important for both personal and professional wellbeing and small students´ development and wellbeing. However, little research has been conducted into emotional intelligence of preprimary teachers, despite their role as “socializers” in early childhood. The Trait Meta-Mood Scale was used to assess levels of perceived emotional intelligence in 418 future preschool teachers and four profiles were identified. Most had adequate levels, but we identified a group of students with inadequate levels of emotional attention. The findings highlight the importance of ensuring that teachers will be helped to develop different components of emotional intelligence during their initial training in college.
El equilibrio emocional de los maestro/as de educación Infantil es importante para su bienestar personal y profesional, y para el desarrollo de sus pequeños alumnos pero existe escasa investigación con este grupo, a pesar del importante papel como socializadores en edades tan tempranas. En este studio se usó el TMMS-24 para evaluar la inteligencia emocional percibida de 418 estudiantes universitarios de Educacion Infantil identificándose cuatro tipo de perfiles. Aunque la mayoría obtuvo niveles adecuados, se encontró un grupo con niveles problemáticos en atención emocional. Los resultados insisten en la importancia de ayudar a estos futuros maestros a desarrollar los diferentes elementos de la inteligencia emocional durante la formación inicial universitaria.

Published: February 2019

Los diversos vínculos entre los individuos y el patrimonio que les rodea han sido ampliamente analizados en la literatura, constatando su complejidad y diversidad dada la naturaleza del concepto de patrimonio. En este artículo nos centramos en el análisis de un tipo de vínculo, el identitario, para tratar de cuantificarlo, ver si existen diferencias entre personas con distinto perfil socioeconómico, y si el grado de vinculación identitaria varía en función del número de programas de educación patrimonial implementados en el territorio. Para ello, hemos elaborado una encuesta que incorpora datos socioeconómicos básicos de los individuos y cuestiones relativas al grado de vinculación identitaria. Los primeros resultados apuntan a que, en general, las personas que han respondido a la encuesta son conocedores de la existencia del patrimonio que les rodea, lo que nos permitirá, en análisis posteriores, medir el grado de vinculación identitaria de los individuos del territorio de Castilla y León, dar respuesta a las hipótesis planteadas en la elaboración de esta encuesta, y poner de manifiesto la importancia de la educación patrimonial en el fomento de la creación de vínculos identitarios.
The different connections between individuals and the heritage which surrounds them have been widely analyzed in the literature, stating their complexity and diversity due to the nature of the concept of heritage. This paper is focused on the analysis of one type of connection, the identity one, in a try to quantify it, to check the existence of disparities between persons with a different socioeconomic profile, and to corroborate whether the identity connection varies according to the number of heritage education programs implemented in the territory. To achieve this, we have performed a survey which includes basic socioeconomic information about individuals and questions related to the degree of identity connection. The first results show that, in general, individuals who answered the survey are aware of the heritage which surrounds them, what will let us, in further analysis, measure the degree of identity connection of individuals from Castile and Leon, give an answer to the hypothesis outlined during the elaboration of the survey, and bring to light the importance of heritage education in the creation of identity connections.

Abstract

Background:
The stigma associated with neurologic disorders plays a part in poor health-related quality of life. The eight-item Stigma Scale for Chronic Illness (SSCI-8) is a brief self-assessment tool for measuring perceived level of stigma. The psychometric performance of the SSCI-8 in people with multiple sclerosis (MS) was assessed.

Methods:
A multicenter, cross-sectional study in adults with relapsing-remitting or primary progressive MS was performed. A nonparametric item response theory procedure, Mokken analysis, was done to preliminarily study the dimensional structure of the SSCI-8. A confirmatory factor analysis (CFA) model was then fit, and the behavior and information covered by the eight items were assessed by parametric item response theory analysis.

Results:
A total of 201 patients (mean ± SD age, 43.9 ± 10.5 years; 60.2% female; 86.1% with relapsing-remitting MS) were studied. The Mokken analysis found that the SSCI-8 is a unidimensional strong scale (scalability index H = 0.56) with high reliability (Cronbach α = 0.88). The CFA model confirmed the unidimensionality (comparative fit index = 0.975, root mean square error of approximation = 0.077). The information covered by the SSCI-8 items ranges from 3.79 to 13.52, for a total of 66.56. More than half (66%) of the SSCI-8 overall information is conveyed by four items: 1 (“Some people avoided me”), 2 (“I felt left out of things”), 3 (“People avoided looking at me”), and 7 (“People were unkind to me”).

Conclusions:
The SSCI-8 shows appropriate psychometric characteristics and is, therefore, a useful instrument for assessing stigma in people with MS.

SynopsisTyrannosaurid dinosaurs had large preserved leg muscle attachments and low rotational inertia relative to their body mass, indicating that they could turn more quickly than other large theropods.MethodsTo compare turning capability in theropods, we regressed agility estimates against body mass, incorporating superellipse-based modeled mass, centers of mass, and rotational inertia (mass moment of inertia). Muscle force relative to body mass is a direct correlate of agility in humans, and torque gives potential angular acceleration. Agility scores therefore include rotational inertia values divided by proxies for (1) muscle force (ilium area and estimates of m. caudofemoralis longus cross-section), and (2) musculoskeletal torque. Phylogenetic ANCOVA (phylANCOVA) allow assessment of differences in agility between tyrannosaurids and non-tyrannosaurid theropods (accounting for both ontogeny and phylogeny). We applied conditional error probabilitiesa(p) to stringently test the null hypothesis of equal agility.ResultsTyrannosaurids consistently have agility index magnitudes twice those of allosauroids and some other theropods of equivalent mass, turning the body with both legs planted or pivoting over a stance leg. PhylANCOVA demonstrates definitively greater agilities in tyrannosaurids, and phylogeny explains nearly all covariance. Mass property results are consistent with those of other studies based on skeletal mounts, and between different figure-based methods (our main mathematical slicing procedures, lofted 3D computer models, and simplified graphical double integration).ImplicationsThe capacity for relatively rapid turns in tyrannosaurids is ecologically intriguing in light of their monopolization of large (>400 kg), toothed dinosaurian predator niches in their habitats.

Aims: To evaluate the efficacy of novel insecticides against the spotted pod borer on rice fallow blackgram.
Study Design: Randomised Block Design (RBD) was used in this study.
Place and Duration of Work: The present study was carried out at College farm Agricultural College, Naira during Rabi 2017-2018 season.
Methodology: The spotted pod borer, Maruca vitrata (Geyer) is a serious pest of blackgram through out the growth period especially in flowering and pod development stages in North Coastal Andhra Pradesh. Management of this pest becomes difficult due to its concealed nature of feeding inside flowers and pods. Different newer insecticides were evaluated for the management of M. vitrata on blackgram cultivar LBG-752 under rice fallow situations with ten treatments replicated thrice.
Results: The current study indicated that among all the insecticidal treatments chlorantraniliprole 9.3% + λ cyhalothrin 4.6% @ 0.5 ml l-1 was found to be very effective by recording 75.91 per cent overall mean reduction in M. vitrata larval population with lowest pod damage (7.04%) over control (60.58%) and also recorded highest grain yield (8.31 q ha-1) followed by chlorantraniliprole 18.5 SC @ 0.0037% and flubendiamide @ 39.35 SC 0.00787% with 72.04 and 67.30 per cent overall reduction in mean larval population of M. vitrata over untreated control. The cost - benefit (C:B) ratio for all the treatments revealed that chlorantraniliprole 18.5 SC @ 0.0037% was highly economical with a C : B of 1: 17.14 followed by spinosad 45 SC with cost - benefit (C:B) ratio 1: 15.28.
Conclusion: Usage of newer insecticides with novel modes of action are highly effective against spotted pod borer with an additional increase in yield of blackgram.
Multicenter Metal–Organic Framework‐Based Ratiometric Fluorescent Sensors
Authors: Wu Shuangyan , Min Hui , Shi Wei , Cheng Peng 
Published: February 2019

AbstractMetal–organic frameworks (MOFs) with multiple emission centers are newly emerging as ratiometric sensors owing to their high sensitivity and high selectivity toward a wide range of targeted functional species. Energy transfer between the light‐absorbing group and emission centers and between different emission centers is the key to rationally design and synthesize MOF‐based ratiometric sensors. A good match between the energy levels of the light‐absorbing groups and emission centers is the prerequisite for MOF‐based sensors to exhibit multiple emissions, and a good match of the MOF‐based sensors and those of the targeted species can increase the sensitivity and selectivity, but this match is highly challenging to obtain via synthesis. MOFs with multiple emission centers can be produced by functionalizing MOFs with multiple lanthanide centers, organic luminophores, dyes, carbon dots, and other such emissive groups. In this progress report, recent advances in the strategies for synthesizing MOFs with multiple emission centers and their applications for ratiometric sensing of solution conditions, including the pH value, and ion, organic molecule, and biomolecule concentrations, are summarized, as are the related sensing mechanisms.

AbstractRationally designed artificial materials, called metamaterials, allow for tailoring effective material properties beyond (“meta”) the properties of their bulk ingredient materials. This statement is especially true for chiral metamaterials, as unlocking certain degrees of freedom necessarily requires broken centrosymmetry. While the field of chiral electromagnetic/optical metamaterials has become rather mature, the field of elastic/mechanical metamaterials is just emerging and wide open. This research news reviews recent theoretical and experimental progress concerning 3D chiral mechanical and optical metamaterials, with special emphasis on work performed at KIT.

AbstractExploring high‐efficiency, stable, and cost‐effective bifunctional electrocatalysts for overall water splitting is greatly desirable and challenging. Herein, a newly designed hybrid catalyst with Cr‐doped FeNi–P nanoparticles encapsulated into N‐doped carbon nanotubes (Cr‐doped FeNi–P/NCN) with unprecedented electrocatalytic activity is developed by a simple one‐step heating treatment. The as‐synthesized Cr‐doped FeNi–P/NCN with moderate Cr doping exhibits admirable oxygen evolution reaction and hydrogen evolution reaction activities with overpotentials of 240 and 190 mV to reach a current density of 10 mA cm−2 in 1 m KOH solution. When used in overall water splitting as a bifunctional catalyst, it needs only 1.50 V to give a current density of 10 mA cm−2, which is superior to its typically integrated Pt/C and RuO2 counterparts (1.54 V @ 10 mA cm−2). Density functional theory calculation confirms that Cr doping into a FeNi‐host can effectively alter the relative Gibbs adsorption energy and reduces the theoretical overpotential. Additionally, the synergetic effects between Cr‐doped FeNi–P nanoparticles and NCNs are regarded as significant contributors to accelerate charge transfer and promote electrocatalytic activity in hybrid catalysts.

Published: February 2019

AbstractWith great advances in wet chemical synthesis of nanoparticles (NPs), plasmonic NPs with various sizes and morphologies are easily available nowadays and demonstrate great potentials in optical, electronic, and biomedical applications. Plasmonic circular dichroism (CD), relating to circular dichroism responses at localized surface plasmon resonance of metal nanostructures, has emerged as a research direction of plasmonics with promising prospects in enantioselective catalysis, chiral separation, and ultrasensitive detections. Herein, plasmonic CD responses of gold nanoparticle based nanostructures are summarized. Two kinds of plasmonic CD phenomena are investigated: structural CD and induced CD. Structural CD is the response from chiral assemblies composed of plasmonic NPs with strong dipole–dipole interactions. Induced CD is the response of nonchiral plasmonic NPs with chiral molecules attached at surface. The weak CD is the result of Coulomb interaction between chiral molecules and plasmonic NPs. Efforts on how to achieve strong CD signals for these two configurations by using chiral molecules and Au nanoparticles are reported. The fabrication of chiral nanostructures, tuning and amplification of CD responses, CD‐based biosensors, chiral catalysis, and future perspectives are presented. The importance of the shape anisotropy of gold nanorods in the generation and amplification of CD signals is especially highlighted.

A decade of flowering phenology of the keystone saguaro cactus (Carnegiea gigantea)
Authors: Renzi Julianna J. , Peachey William D. , Gerst Katharine L. 
Published: February 2019

Premise of the StudyPhenology is the study of biological life cycle events, such as flowering and migration. Climate patterns can alter these life history events, having ecosystem‐wide ramifications. For example, warmer springs are associated with earlier leaf‐out for many species, impacting species interactions and growing‐season carbon dynamics. While phenological research has been conducted extensively in temperate regions, relatively little is known about the phenological responses in arid and semi‐arid regions.MethodsIn this study we looked at the flowering phenology of a keystone species in the Sonoran Desert, the saguaro cactus (Carnegiea gigantea). The timing and abundance of flowering was observed on 151 individuals for 10 years at a site near Tucson, Arizona, USA. Using six phenological traits, we explored the relationship between saguaro size and flowering and the climatic drivers of flowering.Key ResultsOur analyses demonstrated how the calculation of phenological traits at the individual versus the population level can yield differing responses to climate variability, suggesting that not all studies examining the same trait (e.g., first day of bloom) are directly comparable. We found that larger cacti began flowering earlier, flowered for longer, and produced more flowers. Warmer temperatures were correlated with advanced onset and higher bloom yields, while increased precipitation appeared to delay onset and reduce bloom yields.ConclusionsGiven that climate models predict that the Southwestern USA will become increasingly warmer with more variable precipitation, saguaros may begin flowering earlier in the season and flower more intensely, which could impact pollen availability and population dynamics.

Premise of the StudyAnAkania‐like inflorescence, including flowers with in situ pollen was recovered from the remarkableKonservat‐Lagerstättelacustrine diatomite deposit at Foulden Maar, Otago indicating the presence of Akaniaceae in southern New Zealand during the early Miocene. The flowers, although slightly smaller than the sole modern Australian species,A. bidwillii, contain pollen grains that are very like that taxon. The pollen also resembles that of the monospecific sister genusBretschneiderafrom Southeast Asia and India, although that taxon has flowers with very different morphology from this genus.MethodsThe floral morphology of the fossil and in situ pollen grains were compared with flowers and pollen grains from extant species of Akaniaceae and related taxa.Key ResultsThe fossil inflorescence and associated pollen are referred to a new, extinct species ofAkania:Akania gibsonorum. The floral structures and pollen resemble those of the modern AustralianAkaniaspecies.ConclusionsThe discovery of fossil flowers ofAkaniain an early Miocene lake deposit in New Zealand, coupled with earlier recognition of Akaniaceae leaves from the Paleocene epoch and wood from the Miocene epoch in South America suggests that the genus was once widespread in former Gondwana landmasses. The extinction of Akaniaceae in New Zealand and South America, and its present relictual distribution in eastern Australia, is most likely related to post‐Miocene climatic cooling.

Published: February 2019

ABSTRACTRigid polyurethane foam (RPUF) composites with triphenyl phosphate (TPhP), aluminum trihydrate (ATH), and zinc borate (ZnB) alone, as well as their binary blends, were prepared via a one‐shot process. The amount of flame retardant (FR) or FR blend was varied from 10 to 50% by polyol weight percentage, and the weight fraction of the blends was also fixed at 40%. The effects of additives on thermal insulation, mechanical, and flame retardancy properties of the composites were investigated. Thermal conductivity of the neat foam (RPUF) decreased from 22.53 to 21.04–21.58 mW m−1K−1. The compressive strength of foams displayed an increase with increasing the amount of TPhP, ATH, and ZnB till 40% by weight. The limited oxygen index values of all foams increased and the flame spread rates of all foams significantly decreased. It was also observed that the flame was self‐extinguished in some cases. The cone calorimeter test results indicated that the FR additives improved the flame retardancy of the RPUF. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2020,137, 47611.
Interactions between Unionida and non‐native species: A global meta‐analysis
Authors: Moore Thomas P. , Collier Kevin J. , Duggan Ian C. 
Published: February 2019

Abstract

Understanding the multiple agents of decline is important for the conservation of globally threatened Unionida (Class Bivalvia), but threats from non‐native species have received limited attention. To address this gap, a global meta‐analysis was conducted aimed at identifying known interactions and mechanisms of impact and informing potential effect pathways for the New Zealand unionid fauna.
The main non‐native groups identified as interacting with unionids were fish (38% of published studies), macrophytes (33%), and vertebrate predators (30%), with ~70% of interactions leading to adverse impacts on mussels. Most studies used field surveys (~50%) and were conducted in rivers (~50%).
Impacts occurred across the unionid life cycle (adult, glochidia, host, and juvenile), and primarily affected processes that determine the transitions between life‐cycle stages (fertilization, infestation, settlement, and maturation). The impacts of non‐native macrophytes and fish were predicted to be greater for transitional stages than the impact of vertebrate predators, which mostly affected adult mussels.
New Zealand Unionida are most likely to be affected by interactions with non‐native species in lowland lakes and waterways, where connectivity for diadromous native fish hosts and high bioinvasion potential intersect.

AbstractSilkworm (Bombyx mori) larvae are widely used to express exogenous proteins. Moreover, some silkworm pupal proteins can be used as drug‐loading materials for selfexpressed oral tolerance drugs. However, several proteins expressed in silkworm pupae cause severe allergic reactions in humans and animals. Interestingly, some baculovirus vectors have been shown to alter the host gene and its expression in insect cells, but this has not been confirmed in silkworm. Here, we analyzed the effects of infection with an empty B. mori baculovirus (BmNPV) vector on silkworm pupal protein expression. Using a proteomics approach, the allergens thiol peroxiredoxin (Jafrac1), 27‐kDa glycoprotein (p27k), arginine kinase, and paramyosin as well as 32 additional differentially expressed proteins were identified. Downregulation of the messenger RNA expression of the four known allergens was observed after BmNPV infection; subsequent changes in protein expression were confirmed by the western blot analysis using polyclonal antibodies prepared with recombinant proteins of the four allergens. Collectively, these data indicate that the four known allergens of silkworm pupae can be reduced by infection ith an empty BmNPV vector to increase the safety of silkworm pupa‐based exogenous protein expression and drug delivery of oral pharmaceuticals. In addition, the four recombinant allergen proteins may contribute to the diagnosis of allergic diseases of silkworm pupa.
