Published: February 2020

The study was designed to investigate computer anxiety as a correlate of use of Information Technology tool by undergraduates of Library and Information Science in Tai Solarin University of Education (TASUED), Ijagun, Ogun State. Descriptive survey design was adopted while Stratified Random Sampling Technique was used to select 169 undergraduates of LIS. A questionnaire designed by the researchers was used for collecting data. Out of the 169 copies of the questionnaire administered 120 copies were returned and used for the analysis. Data was analyzed by Simple percentages, frequency, Mean and Standard Deviation and Pearson product moment correlation. Findings show that the level of computer anxiety among LIS undergraduates is high. The available IT tools among LIS undergraduates are mobile technology, laptops, CD-ROM, printers and internet search engines. The most frequency utilized IT tools among LIS undergraduate are mobile technology and laptops. The impact of computer anxiety on students’ utilization of IT tools is high. The major constraints of computer anxiety towards the utilization of IT tools among LIS undergraduates are level of computer anxiety and lack of conducive environment. A null hypothesis was tested which revealed that there is a significant relationship between computer anxiety and students’ utilization of IT tools among the LIS undergraduates surveyed. The study therefore recommends that the management of TASUED should provide more conducive learning environment, adequate IT infrastructural facilities, computer literacy should be encouraged to help lower anxiety and reduce stress in an IT environment.Keywords: computer anxiety, computer literacy, Tai Solarin University, undergraduates

Published: February 2020

AbstractImportance: In Chinese-speaking societies, a reliable and valid measure is needed to enable early identification of young children’s challenges in sensory processing.Objective: To examine the psychometric properties of the Chinese version of the Infant/Toddler Sensory Profile (ITSP–C) when used with Taiwanese children.Design: Prospective study.Setting: Multiple settings.Participants: Participants were 367 typically developing (TD) infants ages 0–6 mo (mean [M] age = 3.44 mo, standard deviation [SD] = 1.82) and 677 toddlers ages 7–36 mo (M age = 22.33 mo, SD = 8.15), along with 42 toddlers with developmental disabilities (DD; M age = 28.4 mo, SD = 6.7).Outcomes and Measures: The ITSP, a caregiver questionnaire that measures how children respond to sensory events in daily life, was translated and cross-culturally adapted into a Chinese version (ITSP–C).Results: Internal consistency was high for the 0–6 mo subscale (α = .80) and the 7–36 mo subscale (α = .82). Test–retest reliability was excellent for the 7–36 mo subscale (intraclass correlation coefficient = .94). Logistic regression analysis demonstrated that the ITSP–C discriminated between children with DD and TD children.Conclusions and Relevance: The ITSP was successfully adapted to Chinese with similar reliability and validity to the original ITSP. The 7–36 mo subscale had a higher level of reliability than the 0–6 mo subscale, and quadrant scores were more reliable than section scores. Moreover, the ITSP–C discriminated children with DD from TD children on the basis of their sensory processing patterns.What This Article Adds: The ITSP–C has sound psychometric properties and support for its use in early identification of sensory processing difficulties in young Chinese-speaking children.

Abstract. Atmospheric aerosols play a crucial role in regional radiative
budgets. Previous studies on clear-sky aerosol direct radiative forcing
(ADRF) have mainly been limited to site-scale observations or model
simulations for short-term cases, and long-term distributions of ADRF in
China have not been portrayed yet. In this study, an accurate fine-resolution
ADRF estimate at the surface was proposed. Multiplatform datasets, including
satellite (MODIS aboard Terra and Aqua) and reanalysis datasets, served as
inputs to the Santa Barbara Discrete Atmospheric Radiative Transfer (SBDART)
model for ADRF simulation with consideration of the aerosol vertical profile
over eastern China during 2000–2016. Specifically, single-scattering albedo
(SSA) from the Modern-Era Retrospective Analysis for Research and
Application, Version 2 (MERRA-2) was validated with sun photometers over eastern
China. The gridded asymmetry parameter (ASY) was then simulated by matching
the calculated top-of-atmosphere (TOA) radiative fluxes from the radiative
transfer model with satellite observations (Clouds and the Earth's Radiant
Energy System, CERES). The high correlation and small discrepancy (6–8 W m−2) between simulated and observed radiative fluxes at three sites
(Baoshan, Fuzhou, and Yong'an) indicated that ADRF retrieval is feasible and
has high accuracy over eastern China. Then this method was applied in each grid
of eastern China, and the overall picture of ADRF distributions over eastern China
during 2000–2016 was displayed. ADRF ranges from −220 to −20 W m−2, and
annual mean ADRF is −100.21 W m−2, implying that aerosols have a strong
cooling effect at the surface in eastern China. With the economic development
and rapid urbanization, the spatiotemporal changes of ADRF during the past 17 years are mainly attributed to the changes of anthropogenic emissions in
eastern China. Our method provides the long-term ADRF distribution over eastern
China for the first time, highlighting the importance of aerosol radiative
impact under climate change.
Swarm field-aligned currents during a severe magnetic storm of September 2017
Authors: Lukianova Renata 
Published: February 2020

Abstract. Swarm satellite observations are used to characterize the
extreme behavior of large- and small-scale field-aligned currents (FACs)
during the severe magnetic storm of September 2017. Evolutions of the
current intensities and the equatorward displacement of FACs are analyzed
while the satellites cross the pre-midnight, pre-noon, dusk and dawn sectors
in both hemispheres. The equatorward boundaries of FACs mainly follow the
dynamics of the ring current as monitored in terms of the SYM-H index. The
minimum latitude of the FAC boundaries is limited to 50∘ magnetic latitude (MLat). The
FAC densities are very variable and may increase dramatically, especially in
the nightside ionosphere during the storm-time substorms. At the peak of
substorms, the average FAC densities reach >3 µA m−2.
The dawn–dusk asymmetry is manifested in the enhanced dusk-side R2 FACs in
both hemispheres. In the 1 Hz data filamentary high-density structures are
always observed. In the pre-noon sector, the bipolar structures (7.5 km
width FACs of opposite polarities adjacent to each other) dominate, while at
the other local times the upward and downward FACs tend to be latitudinally
separated. The most intense small-scale FACs, up to ∼80 µA m−2, are observed just in the post-midnight sector. Simultaneous
magnetic and plasma perturbations indicate that this structure is likely a
current system of a mesoscale auroral arc.

Een mentaliteitsgeschiedenis van slachtofferemancipatie
Naar aanleiding van een door socioloog Bas van Stokkom georganiseerde conferentie over de grenzen van slachtofferemancipatie schetst de auteur een korte mentaliteitsgeschiedenis van de versterkte positie van het slachtoffer in strafrecht en samenleving sinds de Tweede Wereldoorlog. Het woord slachtoffer heeft niet alleen in verschillende tijden maar ook in verschillende contexten een andere lading gekregen. De auteur behandelt de vraag waar de theoretische en praktische grenzen van de emancipatie van het slachtoffer in het strafrecht liggen.

Published: February 2020

Con este trabajo pretendemos destacar la importancia que tiene la incorporación de lenguas artificiales, creadas con fines artísticos, a los argumentos de ficción de obras literarias y audiovisuales. En segundo lugar, trazamos un recorrido por algunos de los diseños lingüísticos más relevantes, tales como el klingon, el na’vi o las lenguas de Juego de Tronos, el dothraki y el valyrio. Finalmente, establecemos una distinción de aquellos proyectos que, si bien no pueden considerarse lenguas propiamente dichas, cobran vital importancia en las novelas o películas en las que se incluyen.
With this work we intend to highlight the importance of the inclusion of artificial languages, created for artistic purposes, in the fictional arguments of literary and audiovisual works. Secondly, we trace a tour through some of the most relevant linguistic designs, such as the Klingon, the Na'vi or the languages of Game of Thrones, the Dothraki and the Valyrian. Finally, we establish a distinction of those projects that, although they can not be considered as proper languages, acquire vital importance in the novels or films in which they appear.
Variación intradialectal del español: ideologías lingüísticas en la juventud de Fuenlabrada
Authors: Pinto Pajares Daniel 
Published: February 2020

Las ideologías panhispánicas fomentadas por las instituciones académicas construyen el marco de un español general cohesionado y homogéneo que garantiza el entendimiento entre diferentes comunidades lingüísticas, frente a las múltiples realizaciones cotidianas que, por su carácter espontáneo y alejado de la normativa estándar, se presentan como versiones deturpadas. Mediante cuestionarios anónimos, hemos realizado una investigación cuantitativa que toma como objeto de estudio el alumnado de Bachillerato de Fuenlabrada. Estudiamos las ideologías lingüísticas que presenta una muestra representativa en torno a la variación intradialectal del español. El español estándar es contrapuesto a las variedades de España e Hispanoamérica y las ideologías lingüísticas detectadas engloban prejuicios respecto a ciertas variedades y a sus hablantes.
Panhispanic ideologies promoted by academic institutions present a framework of a cohesive and homogeneous general Spanish language that guarantees understanding between different linguistic communities. This stands in opposition to the multiple daily realizations whose spontaneity and non-normative nature is presented as deviant. By means of anonymous questionnaires, we have carried out a quantitative research with Baccalaureate students from Fuenlabrada as objects of study. We analysed the linguistic ideologies presented in a representative sample regarding the intradialectal variation of the Spanish language. Standard Spanish is contradictory to the varieties of Spanish in Spain and Spanish America and the detected linguistic ideologies include prejudices with respect to certain varieties and their speakers.
En torno a los valores pragmáticos de la evidencialidad: una nueva aproximación a las relaciones entre evidencialidad e ironía en español
Authors: Rodríguez Ramalle Teresa María 
Published: February 2020

En este artículo me propongo contrastar el comportamiento de dos tipos de elementos vinculados con la expresión de la evidencialidad en español, al parecer y por lo visto, y las locuciones consecutivas ilativas así que, conque, de manera/modo que. Mi objetivo es demostrar que la ironía, como interpretación que se documenta en los evidenciales morfológicos, también se puede atestiguar en español, si bien de manera distinta según el modo en que se expresa la fuente de la información: en el caso de al parecer y por lo visto como marcas de ironía, según ya apunta Santamaría (2009); en cuanto a las locuciones consecutivas ilativas, como indicadores. Demostraré que la manera de explicar la evidencialidad a partir de la relación entre situaciones discursivas, de acuerdo con el modelo formal que desarrolla Speas (2010), ayuda también a comprender el comportamiento como indicadores de ironía de las locuciones consecutivas ilativas en contextos concretos.
In this article I will contrast the behavior of two types of discursive particles linked to the expression of the evidentiality in Spanish, al parecer, por lo visto, and illative conjunctions: así que, conque, de manera/modo que. My goal is to show that irony can also be documented in these two types of evidential structures in Spanish, but in a very different way: in the first case as ironic markers, as it was pointed out by Santamaría (2009), in the second, as indicators of irony. According to Speas (2010), I will demonstrate that the way to explain the evidentiality from the relationship among discursive situations also helps us to understand the behavior as indicators of the illative conjunctions.

Published: February 2020

Background: Illegal mining pitch and metal ores processing sites are frequently seen in many parts of Nigerian communities. Gold ore processing is widespread in communities of Zamfara State. These activities produce significant amount of dust that pollute the environment.
Aim: The study was conducted to determine the extent of exposure to lead and mercury in artisanal gold miners in Bagega and Kawaye districts and Yargalma village of Anka and Bukkuyum Local Government Areas respectively.
Methods: Seventy gold ore miners were recruited from twelve different mining or processing sites of the affected villages. Serum lead determination was carried out using Atomic Absorption Spectrophotometer (AAS Perkin Elmer, 6300 model USA) and mercury was determined by cold vapor atomic absorption spectrometry (Spectra-10 varian).
Results: The blood lead and mercury levels of the exposed individuals ranged between 15 – 561.2 µg/dl and 0.21 – 196 µg/dl respectively. Majority (75.7%) had blood lead levels beyond 45 µg/dl with average mean of 368.62±15.20 and mean blood mercury levels of 168.86±8.92 µg/dl. The blood lead and mercury levels were significantly (p<0.05) high in 16-30 age bracket compared to 0-15 and 31-45 age groups. Similarly, Individuals from Bagega village had significantly (p<0.05) high blood lead and mercury levels compared to Kawaye and Yargalma villages. The high blood lead and mercury levels recorded in this study are far above OSHA permissible limit (40 µ/dl) and are therefore a call for concern.
Conclusion: The results indicate the co-exposure to lead and mercury in the artisanal gold miners. The individuals in age bracket 16-30 years are at high risk of synergistic adverse health effects of lead and mercury toxicities. The exposed individuals require urgent medical attention for proper intervention and possible total withdrawal from the work.

Abstract

Objectives
Chromogranin A (CgA) is regarded as an indicator of sympathetic tone and adrenomedullary system activity. Catestatin is one of CgA-derived fragments through proteolytic processing. Many studies have confirmed the correlation between anxiety/depression and the salivary CgA level. The study was to investigate the associations between anxiety/depression and plasma CgA/catestatin levels in healthy workers without cardiovascular disease.

Methods
The study included 263 healthy workers (175 men and 88 women). The symptoms of anxiety and depression were measured with the Hospital Anxiety and Depression Scale (HADS). Plasma CgA and catestatin levels were measured by ELISA kits.

Results
In bivariate correlation analysis, anxiety and depression were positively associated with plasma CgA level, respectively (r = 0.298, P &lt; .001; r = 0.304, P &lt; .001), but not significantly associated with plasma catestatin level.
The anxiety group had significantly higher plasma CgA level than that in the no-anxiety group (median 158.60 vs 70.90, P &lt; .001). The similar results were found for depression scales. The depression group had significantly higher plasma CgA level (median 145.60 vs 82.40, P &lt; .001).
In the multiple linear regression model, after adjusting for age, gender, and BMI, anxiety was positively correlated with plasma CgA level (β = 0.359, P &lt; .001), while anxiety was negatively correlated with plasma catestatin level (β = −0.128, P = .044), depression was also positively correlated with plasma CgA level (β = 0.343, P &lt; .001).

Conclusions
Plasma CgA was associated with anxiety and depression in healthy workers. It can be considered as the blood indicator for the evaluation of anxiety and depression.

AbstractObjectiveTo investigate whether the burden of white matter hyperintensities (WMHs) is associated with the risk of developing levodopa‐induced dyskinesia (LID) in Parkinson’s disease (PD).MethodsAccording to the Clinical Research Center for Dementia of South Korea WMH visual rating scale, 336 patients with drug‐naïve early stage PD (follow‐up >3 years) were divided into two groups of PD with minimal WMHs (PD‐WMH–; n = 227) and moderate‐to‐severe WMHs (PD‐WMH+; n = 109). The Cox regression model was used to estimate the hazard ratio for the development of LID in the PD‐WMH + group compared with the PD‐WMH– group, while adjusting for age at PD onset, sex, striatal dopamine depletion, and PD medication dose. Additionally, we assessed the effects of WMH burden rated by the Scheltens scale and regional WMH distribution on the development of LID.ResultsPatients in the PD‐WMH + group were older and had more severe parkinsonian motor signs despite comparable striatal dopamine transporter availability than those in the PD‐WMH– group. Patients in the PD‐WMH + group had a higher risk of developing LID (hazard ratio, 2.66; P < 0.001) than those in the PD‐WMH– group after adjustment for other confounding factors. A greater WMH burden was associated with earlier occurrence of LID (hazard ratio, 1.04; P = 0.001), although the effects of WMHs on LID development did not exhibit region‐specific patterns.InterpretationThe present study demonstrates that the burden of WMHs is associated with occurrence of LID in patients with PD, suggesting comorbid WMHs as a risk factor for LID.
Bacterial Magnetosomes as Novel Platform for the Presentation of Immunostimulatory, Membrane‐Bound Ligands in Cellular Biotechnology
Authors: Mickoleit Frank , Jérôme Valérie , Freitag Ruth , Schüler Dirk 
Published: February 2020

AbstractCell–cell interactions involving specific membrane proteins are critical triggers in cellular development. Ex vivo strategies to mimic these effects currently use soluble proteins or (recombinant) presenter cells, albeit with mixed results. A promising alternative are bacterial magnetosomes, which can be selectively transformed into cell‐free membrane–protein presenters by genetic engineering. In this study, the human CD40 Ligand (CD40L), a key ligand for B cell activation, is expressed on the particle surface. Functionality is demonstrated on sensor cells expressing the human CD40 receptor. Binding of CD40L magnetosomes to these cells triggers a signaling cascade leading to the secretion of embryonic alkaline phosphatase. Concomitantly, the CD40–CD40L interaction is strong enough to allow cell recovery by magnetic sorting. Overall, this study demonstrates the potential of magnetosomes as promising cell‐free tools for cellular biotechnology, based on the display of membrane‐bound target molecules, thereby creating a biomimetic interaction.
