Does one size fit all? The scope and type of error in direct feedback effectiveness
Authors: Kao Chian-Wen 
Published: April 2022

Abstract
This study is an attempt to investigate the scope and type of error in feedback effectiveness. This study consists of two experiments. One was conducted to investigate the feedback effects on a rule-based error type (i.e. subject–verb agreement errors) and the other was conducted to investigate the effects on a lexically-based error type (i.e. verb–noun collocation errors). In addition, the scope of error was investigated in both experiments. In terms of the rule-based error type, results for the immediate posttest writing task showed focused feedback to be effective for the narrowly defined subject–verb agreement errors (i.e. subject–verb agreement involving lexical verbs or copula be). In the delayed posttest writing task, the benefit still persisted for the narrowly defined subject–verb agreement errors. In terms of the lexically-based error type, results for the immediate posttest writing tasks showed focused feedback to be effective for the broadly defined verb–noun collocation errors (three or four collocation errors made and corrected in pretests). In the delayed posttest writing tasks, the benefit still persisted for the broadly defined verb–noun collocation errors broadly defined. These findings suggest that the notion of error type should influence the feedback effectiveness. Theoretical implications regarding the role of notice in the second language acquisition process were discussed based on the results obtained in this study.

Abstract
Super-resolution image acquisition has turned photo-activated far-infrared thermal imaging into a promising tool for the characterization of biological tissues. By the sub-diffraction localization of sparse temperature increments primed by the sample absorption of modulated focused laser light, the distribution of (endogenous or exogenous) photo-thermal biomarkers can be reconstructed at tunable ∼10−50 μm resolution. We focus here on the theoretical modeling of laser-primed temperature variations and provide the guidelines to convert super-resolved temperature-based images into quantitative maps of the absolute molar concentration of photo-thermal probes. We start from camera-based temperature detection via Stefan–Boltzmann’s law, and elucidate the interplay of the camera point-spread-function and pixelated sensor size with the excitation beam waist in defining the amplitude of the measured temperature variations. This can be accomplished by the numerical solution of the three-dimensional heat equation in the presence of modulated laser illumination on the sample, which is characterized in terms of thermal diffusivity, conductivity, thickness, and concentration of photo-thermal species. We apply our data-analysis protocol to murine B16 melanoma biopsies, where melanin is mapped and quantified in label-free configuration at sub-diffraction 40 µm resolution. Our results, validated by an unsupervised machine-learning analysis of hematoxylin-and-eosin images of the same sections, suggest potential impact of super-resolved thermography in complementing standard histopathological analyses of melanocytic lesions.

Abstract

Objectives
Atorvastatin is commonly used medication to achieve low levels of low-density lipoproteins (LDL). Cholesteryl ester transfer protein (CETP) and LDL receptor (LDLR) genetic variants can affect the cholesterol transport and hence may affect on atorvastatin response. This study aimed to investigate the influence of LDLR AvaII, CETP TaqIb, and Rs1532624 on the efficacy of 20 mg atorvastatin among Jordanian hyperlipidemic patients.

Methods
One hundred and 50 blood samples were collected from hyperlipidemic patients in the University of Jordan Hospital. Polymerase chain reaction-restriction fragment length polymorphism was used for genotyping of LDLR AvaII and CETP TaqIb genetic variants. The genotyping of CETP Rs1532624 variant was done by Sanger DNA-Sequencing.

Results
LDLR AvaII and CETP TaqIb and Rs1532624 variants showed a significant (p value < 0.05) association with the baseline of the LDL at the time of diagnoses. On the other hand, none of the tested genetic variants showed a significant (p value>0.05) association with LDL reduction after atorvastatin therapy.

Conclusions
Results demonstrated a significant association between the LDLR AvaII and CETP TaqIb, and Rs1532624 genetic variants with the LDL baseline level. However, the atorvastatin therapy among hyperlipidemic patients of Jordanian origin was not affected by any of the tested variants.

(0.5 ≤ x ≤ 1.2) with a layered tetragonal I4/mmm K2NiF4-type structure, and one ternary compound Gd2SrCo2O7 with a tetragonal P42/mnm structure. The existence of six binary oxide compounds Gd2SrO4, GdCoO3, Sr2Co2O5 (R), Sr6Co5O15, Sr5Co4O12 and Sr14Co11O33 was confirmed. This metastable phase diagram is of technological interest in the controlled preparation of single-phase complex oxides. New phases Gd0.375Sr2.625Co2O7−δ
and τ4 with an orthorhombic Immm structure were found in the quenched samples. Differences between the present metastable phase diagram and the reported 1100 °C equilibrium one are discussed.
A longitudinal study of topic continuity in Chinese EFL learners’ written narratives
Authors: Liu Yan , Cai Jinting 
Published: April 2022

Abstract
This paper reports a longitudinal study of topic continuity in Chinese EFL learners’ English written narratives by tracking their dynamic change of referential choices over two years. The proportional distribution of referential forms were calculated and texts produced by learners were analyzed. The calculation and analysis yielded the following findings. Firstly, while the general distribution of referential forms follows Givón’s cross-linguistic topic continuity scale, indicating the dominant role of discourse context in referring, quite a few instances deviate from this scale, suggesting the modulating effect of multiple factors, including L1 influence and articulators’ cognitive pressure. Secondly, with an increase in English exposure, L2 learners’ use of the typical referring form in each context displayed an increasing tendency over time. Finally, the developmental paths of L2 referential choices exhibited individual variability. These findings pointed to variation in interlanguage and the modulating effect of non-linguistic or internal cognitive factors on reference production.
The relationship between metrical, syntactic, and rhetorical structure in the Rigveda: the gāyatrī stanza
Authors: Klein Jared S. 
Published: April 2022

Abstract
It is often said, independently of any linguistic evidence, that the refusal of the redactors of the Rigveda text to allow sandhi between the second and third eight-syllable verses (pādas) of the three-line Rigvedic gāyatrī stanza is based on their parallel convention in the cases of the four-line triṣṭubh and anuṣṭubh stanzas, where the first two lines predominantly serve as an independent discourse unit (distich) relative to the last two. This paper attempts to provide independent linguistic evidence for the redactors’ treatment of the gāyatrī line by examining the syntactic and rhetorical structures of the first 300 gāyatrī stanzas in the Rigveda. The results show that nearly 60% of these show a clear syntactic and/or rhetorical break at the end of the second verse, whereas fewer than 19% show such a boundary following the first verse. While this does not prove that the redactors’ procedure was based on syntactic-rhetorical structure alone, it is maintained that the redactors could not have been unaware of the preponderance of a linguistic break following the second verse of the gāyatrī and that, even if they were influenced by their treatment of the distich boundary in four-line stanzas, their procedure was not simply a matter of analogical extension independent of linguistic considerations.

Abstract
We captured a male individual of Coelops frithii during a cave survey in the Makawanpur District of central Nepal on March 3, 2021. A colony with 15 individuals of this species was found roosting in a narrow and moist cavity of the Sarasawati cave situated in Raksirang Rural Municipality. The species was identified by its small size and characteristic funnel shaped ears with large antitragus at the base of posterior end of ear pinna and externally invisible and nodular tail. This is the first record of the genus Coelops for Nepal and western most record of the species.

The quest for magic: recent advances in C(sp3)–H methylation
Authors: Feng Kaibo 
Published: April 2022

Abstract
Frequently referred to as the “magic methyl” effect, the introduction of a methyl group into a biologically active molecule has the potential to drastically alter its physical and biological properties and significantly increase potency. This effect is most pronounced when the methyl group is added at the α-position of an aliphatic heterocycle or ortho to a large rotatable group on an aromatic ring. Although seminal developments in C–H activation strategies offered solutions to the latter, until recent years there had been no selective and functional-group-tolerant method for C(sp3)–H methylation at late stages of synthesis. For many years, the lack of a generally applicable methylation strategy necessitated arduous de novo synthesis approaches to access methylated drug candidates, and discouraged further investigation and understandings of the magic methyl effect. This review will provide a summary of the most recent advances that enabled non-directed late-stage C(sp3)–H methylation, including through hydride transfer, chemical or anodic oxidation, and photocatalytic hydrogen atom transfer.
Synergistic effect of organic-Zn(H2PO2)2 and lithium containing polyhedral oligomeric phenyl silse-squioxane on flame-retardant, thermal and mechanical properties of poly(ethylene terephthalate)
Authors: Yan Xiaofei , Zhao Zhikui , Fang Jie , Li Jiawei , Qi Dongming 
Published: April 2022

Abstract
A novel synergy flame retardant system of poly(ethylene terephthalate) (PET)/organic-Zn(H2PO2)2/lithium containing polyhedral oligoheptyl silse-squioxane (Li-Ph-POSS) composites was prepared by the melt-blending method to improve the flame retardancy of PET. The synergistic effect of organic-Zn(H2PO2)2 and Li-Ph-POSS on the flame retardancy, thermal, and mechanical properties of the PET composites was investigated by the limiting oxygen index, vertical burning test, cone calorimeter, thermogravimetric analysis, differential scanning calorimeter, tensile tester, and dynamic mechanical analysis, respectively. The results show that the synergistic flame retardant effect between organic-Zn(H2PO2)2 and Li-Ph-POSS improves both the flame retardancy and the crystallization of PET. Moreover, the Li-Ph-POSS has a positive effect on the mechanical property of PET. This work provides a promising strategy for mitigating the fire hazard of PET using this synergy flame retardant system.

Published: April 2022

Abstract
The standardisation of nuclear reaction cross section data is an integral part of optimisation of production routes of medical radionuclides. The production cross sections are available for the reactor and cyclotron produced radionuclides to be used for diagnostics or therapeutic procedures. The types of nuclear data needed, and the sources of their availability are summarized. The method of standardisation of charged-particle data is briefly described. A historical overview of research work in Pakistan in this direction is given. Examples of a few medically important radionuclides, such as 64Cu, 86Y, 89Zr, 103Pd, 186Re, etc., whose data were standardised and evaluated are highlighted. Calculated thick target yields from the recommended data are given. Some new directions in the nuclear data research are outlined.

Published: April 2022

Abstract
Many scientists who are members of the Japan Society of Nuclear and Radiochemical Sciences have been involved in academic activities in response to the Fukushima Daiichi Nuclear Power Plant accident. Projects had been implemented that include determining radionuclides in environmental samples, identifying the distribution of radionuclides by large-scale soil monitoring, tracing radionuclide discharge time series, clarifying environmental dynamics of radionuclides, etc. For the last 10 years, these results have been shared and discussed in annual workshops partly sponsored by the society. This review summarizes the studies yielding these results, and they include reconstruction of the 131I distribution on soil by long-lived 129I analysis, reconstruction of the radioactive plume transport, identification of biological resuspension sources, discovery and characterization of cesium particles, and parameterization of the environmental behavior of radiocesium for dose assessment.
The role of natural disasters in the semiotic transformations of culture: the case of the volcanic eruptions of Mt. Merapi, Indonesia
Authors: Nazaruddin Muzayin 
Published: April 2022

Abstract
This study examines the entanglements of natural disasters and cultural changes from an ecosemiotic point of view. Taking the case of Mt. Merapi’s periodic eruptions and the locals’ interpretations of such constant natural hazards, it is based on empirical data gathered through longitudinal qualitative fieldworks on the local communities surrounding this volcano. In order to adapt to the constant natural hazards in their environment, disaster prone societies develop unique sign systems binding cultural and natural processes. This study shows that traditionally, unique sensorial-environmental sign systems have formed the basis of communication between human and environment, allowing the locals to perceive the eruption as a communication involving them and local environmental agencies. Recently, the eruptions have triggered the adoption of new livelihoods of local people, as well as the acceptance of new scientific signs for the interpretation of the activities of the volcano. The latter has been accompanied by significant cultural changes, including the adoption of the idea of progress and the transformation of the previous entanglements of local culture and its natural environment. The study concludes that natural disasters, entangled with ongoing social transformations, may play a fundamental role as triggers of semiotic change in a community. Such semiotic change can in turn modify the interpretation of the natural disaster itself, and in that way shift the way humans perceive and interact with their environment.

Abstract
Edwards, T, Piggott, B, Banyard, HG, Haff, GG, and Joyce, C. The effect of a heavy resisted sled-pull mesocycle on sprint performance in junior Australian football players. J Strength Cond Res 37(2): 388–393, 2023—This study assessed the effect of heavy resisted sled-pull training on sprint times and force, velocity, and power characteristics in junior Australian football players. Twenty-six athletes completed a 6-week resisted sled-pull training intervention which included 10 training sessions and 1-week taper. Instantaneous velocity during 2 maximal 30 m sprints was recorded 1 week before and 1 week after the intervention with a radar gun. Velocity-time data were used to derive sprint performance and force, velocity, and power characteristics. A paired t-test assessed the within-group differences between preintervention and postintervention testing. Statistical significance was accepted at p ≤ 0.05. Hedges' g effect sizes (ESs) were used to determine the magnitude of change in dependent variables. Maximum velocity (ES = 1.33) and sprint times at all distances (ES range 0.80–1.41) significantly improved after heavy resisted sled-pull training. This was reflected in sprint force, velocity, and power characteristics with significant improvements in relative theoretical force (ES = 0.63), theoretical velocity (ES = 0.99), relative maximum power (ES = 1.04), and ratio of horizontal to vertical force (ES = 0.99). Despite the multifactorial nature of training and competing physical demands associated with preseason training, these findings imply that a short, resisted sled-pull training mesocycle may improve sprint performance and underlying force, velocity, and power characteristics in junior athletes.
Comparación de guadua angustifolia kunth expuesta a agentes atmosféricos, protegida y sin protección, mediante inspección visual y microscopía

Published: April 2022

En este estudio experimental, se analiza el deterioro de la guadua frente a la exposición directa a agentes atmosféricos, (radiación solar, lluvia, viento y cambios de temperatura ambiente) para evaluar el comportamiento de tratamientos de protección, mediante un análisis comparativo de elementos expuestos protegidos y sin protección en idénticas condiciones. Se desarrolló una estructura en guadua angustifolia kunth en la cual se incluyeron diferentes ángulos en los elementos y sobre algunos de estos se aplicó una película protectora de lasur con varias preparaciones previas de la superficie.
Se expuso el ensayo a la intemperie durante 11 meses, durante los cuales se realizó seguimiento al deterioro de la estructura mediante la inspección visual y documentación fotográfica en forma periódica. Posteriormente, se tomaron muestras de los elementos expuestos para ser analizados bajo microscopio de barrido electrónico.
Se pudo identificar como lesión primaria la foto-degradación, evidente en los elementos con y sin protección, presentando más impacto en los elementos horizontales, que reciben mayor radiación solar. Derivadas de la foto-degradación, se encontraron otras lesiones secundarias, como la presencia de fisuras y grietas, las cuales comprometen la superficie del material y permiten la aparición de agentes bióticos en las guaduas.
Las superficies no expuestas directamente a la radiación solar no presentaron afectaciones significativas, por lo que se concluyó que el principal aspecto frente al que se debe proteger la guadua es la radiación solar directa y que los procedimientos de protección aplicados no ofrecen un buen desempeño real frente a las condiciones del ensayo, planteando la necesidad de buscar alternativas eficientes frente a esta condición.
Consumo y venta del huevo de codorniz en Costa Rica
Authors: Zamora-Sanabria Rebeca , Chacón-Villalobos Alejandro 
Published: April 2022

El sector coturnicultor costarricense está en proceso de desarrollo; aún no se han documentado en la literatura aspectos productivos, económicos, de mercado o comercialización asociados al mismo. El objetivo de este trabajo es generar información sobre la comercialización y el consumo del huevo de codorniz en Costa Rica. La investigación tuvo lugar entre enero y diciembre del 2019 en la Gran Área Metropolitana costarricense. Se realizaron consultas a 14 productores con respecto al entorno comercial, a la vez que se evaluaron las pautas de consumo de huevo de codorniz en una muestra de 300 personas. La mayoría de los productores (10) se dedican a la producción exclusiva de huevo en sistemas productivos que mayoritariamente no superan las 200 aves (11), principalmente alojadas en jaulas artesanales (10), y donde el uso de registros productivos no se ha implementado (11). Se emplea esencialmente alimento para gallinas de producción(13), sin distinción de la etapa productiva del ave (11), sin un manejo reproductivo en seis de los casos o bien empleando cruces consanguíneos (5). El huevo se comercializa principalmente en empaques de 24 huevos ($2,42 por empaque) y en conservas de 200 g ($2,5). En términos de compra, la mayoría de los consumidores expresó no adquirir el huevo de codorniz (74%), siendo el consumo esporádico aún entre quienes si lo obtienen (51,4% una vez al mes). La presentación preferida de compra es el huevo fresco empacado (46,8%), que es preparado principalmente como huevo duro hervido (66,2%). La producción y consumo de huevo de codorniz en Costa Rica se encuentra poco tecnificada y diversificada lo cual concuerda con un perfil de productores pequeños y un bajo consumo.
