College students' trait gratitude and subjective well-being mediated by basic psychological needs
Authors: Wang Yanhua
Published: April 2020

I explored how trait gratitude affects subjective well-being and whether this relationship is mediated by the fulfillment of basic psychological needs. Participants were 481 Chinese undergraduate students, who responded to measures of trait gratitude, basic psychological needs fulfillment,
and subjective well-being (SWB). The results revealed that trait gratitude, fulfillment of basic psychological needs, and SWB were significantly correlated with each other. Further, structural equation modeling results indicated that trait gratitude was a significant predictor of SWB, and
this effect was partially mediated by the fulfillment of basic psychological needs. My findings provide new insight into the mechanism of how gratitude can promote SWB.
Openness to experience, job characteristics, and employee creativity: An interactionist perspective
Authors: Zhang Wengang , Xu Feng , Sun Baiqing
Published: April 2020

There is considerable ambiguity about how the personality trait of openness to experience affects employee creativity. We investigated how the interactions of openness to experience with decision autonomy, and with task interdependence can influence employee creativity. Analysis of
matched data from 217 supervisor–employee dyads showed a direct influence of openness of experience and the decision autonomy and task interdependence job characteristics on employee creativity. Furthermore, we examined the moderating roles of decision autonomy and task interdependence
in the effect of openness to experience on employee creativity, and found that openness to experience was positively related to employee creativity and task interdependence was negatively related to employee creativity. Further, decision autonomy positively moderated the relationship between
openness to experience and employee creativity, whereas the interaction between task interdependence and openness to experience did not have a significant impact on employee creativity. Theoretical and practical implications are discussed.

Abstract

The incidence of sexually transmitted infections (STI) that occurred in Denpasar since 2010 until the year 2012 has increased. This study aims to provide an illustration of the incidence of STIs in Denpasar City in 2016 and its influencing factors. This was an analytical study of data derived from medical records of patients who performed STI examination at four public health centers (puskesmas) in Denpasar City from January to December 2016. Data were assessed by univariate and bivariate analyses using chi-square test. The results showed that from a total of 1,397 respondents, 18.2% were diagnosed as STI positives. The result of bivariate analysis showed that the significant factors for the incidence of STI were female sex worker’s customers (OR=2.3 95% CI: 1.7-3.2; p<0.001), employed respondents (OR=2.2; 95% CI: 1.7-2.9; p<0.001), male (OR=1.6; 95% CI: 1.2-2.1; p=0.001) and married (OR=1.4; 95% CI: 1.1-1.9; p=0.014). It is recommended that each puskesmas should conduct community outreach activities especially to female sex worker’s customers as one of groups with high risk of STI infections.

Design of multiplierless comb compensators with magnitude response synthesized as sinewave functions
Authors: Jovanovic-Dolecek Gordana
Published: April 2020

This paper presents a research on design of multiplierless comb compensators
with magnitude response synthesized as sinewave functions. First, it is
elaborated the importance of comb decimation filter and why we need its
compensator. In continuation are presented some favorable characteristics of
comb compensator. The compensators, with magnitude characteristic
synthesized as sinewave functions fulfill those favorable characteristics.
Next, are described some most important results on design of compensators
with sinewave-based magnitude responses including single and cascaded
sinewave-based functions. In all designs are presented the overall
corresponding magnitude responses and the zooms in the passband. The
parameters of design generally depend only on number of cascaded combs and
generally do not depend on decimation factor. Design parameters are
presented in tables along with the corresponding required number of adders.
Does Mandatory Retrospective Hedge Effectiveness Assessment under ASC 815 Provide Risk-Relevant Information?
Authors: Chen Zhihong , Liu Alfred Zhu , Seow Gim S. , Xie Hong
Published: April 2020

SYNOPSIS

Current accounting standards permit special accounting treatment of derivatives used for hedging purposes. However, the requirement to perform periodic, retrospective assessments of hedge effectiveness and to disclose a quantitative accounting measure of hedge ineffectiveness (AMHI) for such derivatives has been controversial. In response to concerns over the compliance costs of this requirement, the FASB removed this requirement in the recently effective ASU 2017-12. However, this change was made with little empirical evidence on the benefits of retrospective effectiveness assessment and quantitative disclosure of AMHI. We document one potential benefit of this requirement to investors by providing initial evidence that (1) AMHI is positively associated with an array of concurrent market- and accounting-based risk measures and (2) investors react negatively to large AMHIs and related disclosures upon 10-K filings. Our findings suggest that this requirement can provide investors with risk-relevant information and shed light on its potential usefulness.
Abnormal Audit Fees and Audit Quality: Evidence from the Korean Audit Market
Authors: Behrend Matthew J. , Khan Sarfraz , Ko Young Woo , Park Sung-Jin
Published: April 2020

Do abnormally high or low audit fees reflect audit quality? In this paper, we re-examine this issue after controlling for the confounding effect of audit hours by using a sample of public firms in the Korean audit market, which publicly discloses both audit fees and audit hour information. While we do not find a significant association between abnormally high audit fees and audit quality, we find that abnormally low audit fees are associated with larger discretionary accruals and a higher likelihood of meeting or beating analyst earnings forecasts. Further, we find that the relationship between abnormally low audit fees and audit quality indicators persists regardless of the level of audit hours. To the extent that audit hours represent audit effort, these findings suggest that greater audit effort alone may not lead to higher audit quality as fee pressure from abnormally low fees may discourage the provision of high-quality audit services.

Authors: GÜLER Erhan
Published: April 2020

In this study, rotational hypersurfaces in the 4-dimensional Euclidean space are discussed. Some relations of curvatures of hypersurfaces are given, such as the mean, Gaussian, and their minimality and flatness. In addition, Laplace-Beltrami operator has been defined for 4-dimensional hypersurfaces depending on the first fundamental form. Moreover, it is shown that each element of the 4×4 order matrix A, which satisfies the condition ∆^I R=AR, is zero, that is, the rotational hypersurface R is minimal.

Ressalta-se a importância de novas pesquisas que possibilitem ampliar o entendimento e os olhares para a formação dos gestores.
Revalidação de diplomas estrangeiros no Brasil
Authors: Santos Dâmaris Pereira dos , Real Giselle Crisitina Martins
Published: April 2020

Objetiva-se apresentar “estado da arte” sobre revalidação de títulos estrangeiros, por meio de revisão sistematizada. Com a utilização dos descritores “revalidação de diploma” e “diploma estrangeiro”, em 6 dos principais bancos de dados do Brasil, foram encontrados 44 trabalhos, dos quais 12 focavam o assunto. Foi possível observar que 83,33% dos estudos analisados tratam de diplomas de medicina após os anos 2002, o que se justifica pela demanda crescente de pedidos de revalidação neste período e área. Também, verifica-se foco de interesse sobre a temática na Universidade Federal da Grande Dourados (UFGD), uma vez que cerca de 42,86% dos autores que publicaram sobre o assunto têm vínculo com essa instituição. Pode-se notar que apesar das ações do Estado brasileiro que age por meio de políticas específicas e centralizadoras, a literatura incipiente revela que, ainda, há embates e tensões sobre o assunto.

Un acercamiento al concepto de comunidad en el universo tradicional negroafricano
Authors: Mballa Louis Valentin
Published: April 2020

El objetivo de este artículo es edificar un marco de comprensión de la realidad comunitaria en África subsahariana tradicional. Los antecedentes del contenido epistemológico del concepto de comunidad muestran que las aportaciones varían en función de los parámetros de análisis de cada autor. Asimismo, se asume que la comprensión de la realidad comunitaria en el universo negroafricano no es posible si no se fundamenta en las variables de la estructura socioantropológica del universo negroafricano: la persona, la familia, el clan, la tribu, la etnia y las religiones tradicionales ancestrales. A través de un análisis de esas variables, se llega a la conclusión de que es necesario guardar las distancias respecto al actual estadocentrismo para repensar los modos de organización comunitaria en África subsahariana tradicional, en toda su diversidad y complementariedad.
La producción de soldados en Filipinas encauzada por la Orden de Predicadores: 1610-1648
Authors: Sales-Colín Kortajarena Ostwald
Published: April 2020

Filipinas se convirtió en un espacio donde se intentó reproducir las mismas formas de organización ensayadas en América, pero la monarquía española en Asia buscaba en esa primera mitad del siglo XVII su expansión y afianzamiento mediante el reforzamiento militar del archipiélago. Este artículo trata de mostrar cómo se desarrollaron las esferas de intereses mancomunados entre el gobierno filipino y la Orden de Predicadores a través de los medios empleados para producir soldados en las islas, así como las dificultades enfrentadas. Las funciones que desempeñaron los dominicos fueron cruciales en un momento en que, a pesar de sus esfuerzos, el número de efectivos militares siempre fue insuficiente. Así, este clero regular se constituyó en un brazo armado del Estado español en Asia y muestra, en cierto modo, cómo el bastión de la fe se convierte, al mismo tiempo, en uno de pretensiones hegemónicas.

Textiles y poblaciones del Holoceno temprano: cordeles, mallas y artefactos plumarios en contextos funerarios de Antofagasta de la Sierra, Puna meridional argentina
Authors: López Campeny Sara María Luisa , Martínez Jorge Gabriel , Rodríguez María Fernanda , Schmitz María Alejandra
Published: April 2020

Este trabajo se enfoca en el análisis de un conjunto de artefactos textiles que conforman el acompañamiento de contextos funerarios detectados en el sitio Peñas de las Trampas 1.1, un alero rocoso ubicado a 3582 msnm en Antofagasta de la Sierra (Catamarca), Puna meridional, República Argentina. Las condiciones climáticas de frío y extrema sequedad propiciaron un grado excepcional de preservación de diversos restos arqueológicos de origen orgánico. Las tecnofacturas bajo análisis fueron elaboradas con diferentes materias primas de origen vegetal y animal, las cuales proceden de dos estructuras funerarias situadas en el interior del mencionado alero y se ubican temporalmente dentro del rango ca. 8440-8000 AP, por lo que constituyen las evidencias mortuorias más antiguas de este sector de la Puna argentina. El estudio de las piezas incluyó un abordaje estructural-técnico y formal-funcional y la identificación taxonómica de las fibras de origen vegetal y de las plumas utilizadas para su confección. Igualmente, se presentan algunos resultados obtenidos a partir de estudios de caracterización química elemental (PIXE) aplicados en elementos de cordelería vegetal que presentaban una alteración de su color original. Entre los resultados obtenidos se destaca una alta selectividad en el uso de un recurso vegetal (Acrocomia aculeata) procedente de un área distante unos 600 km, aproximadamente. Lo anterior, sumado a una serie de rasgos técnicos, estructurales y formales presentados por la muestra, permite trazar vínculos con tradiciones textiles indígenas del área oriental y zonas ribereñas como el Gran Chaco. Asimismo, la notable calidad técnica registrada en la mayor parte de los atributos constructivos testimonia una tradición textil cuyo conocimiento en el manejo de las fibras parece remontarse mucho más atrás en el tiempo de lo hasta ahora pensado.
Indicadores tecnológicos de colonización en contextos de superficie del Macizo del Deseado (Santa Cruz, Argentina)
Authors: Hermo Darío Omar , Mosquera Bruno , Vargas Gariglio Jorgelina , Pérez Alejo
Published: April 2020

Los conjuntos líticos del Macizo del Deseado correspondientes a la transición Pleistoceno-Holoceno temprano han sido caracterizados por la presencia de artefactos unifaciales, elaborados sobre lascas grandes, generalmente espesas y formatizados mediante retoque marginal. Estas características tecnológicas fueron registradas en diferentes contextos del Macizo del Deseado, como Los Toldos, Piedra Museo, Cueva Maripe, entre otros; como así también en el noroeste santacruceño. En este trabajo evaluamos conjuntos líticos de contextos estratigráficos y de sitios en superficie con el objetivo de identificar indicadores de estas tecnologías tempranas. Observamos que tanto en los conjuntos del Pleistoceno final - Holoceno provenientes de sitios en estratigrafía, como en contextos en superficie sin control cronológico, se repiten ciertas características tecnológicas y morfológicas. Estas características hablan de preferencias tecnológicas (presencia de determinados grupos tipológicos, selección de formas base, técnicas de manufactura y acondicionamiento de las herramientas) que pueden ser tenidas en cuenta a la hora de evaluar conjuntos artefactuales de superficie.

Published: April 2020

El objetivo de este trabajo es presentar los nuevos resultados obtenidos en torno a las ocupaciones tempranas en el sitio La Gruta 1, área de La Gruta, extremo sur del Macizo del Deseado, Patagonia argentina. Ã?stos se refieren tanto a la transición Pleistoceno-Holoceno como al Holoceno temprano y abarcan aspectos paleoambientales, nuevos fechados radiocarbónicos, además de la disponibilidad y utilización de materias primas. Se presentan los resultados de los nuevos análisis polínicos, realizados en un mallín del área ubicado en la meseta central, cerca de la localidad arqueológica Viuda Quenzana, con una edad basal de ca. 12.500 años A.P. (14.500 cal AP). Por otra parte, a partir de los resultados obtenidos se infiere una vegetación similar a la reconstruida por otros registros polínicos del área que sugieren condiciones húmedas durante el segundo período de ocupación humana del sitio arqueológico La Gruta 1, comprendido entre ca. 11.000 y 8000 cal AP Las evidencias procedentes de la ampliación de las excavaciones en este sitio muestran la falta de continuidad entre los fechados correspondientes a la transición Pleistoceno-Holoceno y los del Holoceno temprano. En ambos períodos existe evidencia de transporte de materias primas desde otros espacios, que incluyen artefactos bifaciales, lo que es consistente con la información obtenida previamente.
Managerial Factors in Investment Risk: Evidence from Polish Mutual Funds
Authors: Filip Dariusz
Published: April 2020

The aim of this study is to examine whether investment risk is related to the managerial factors characterising portfolio managers. The study employs four risk measures and a set of individual manager characteristics, including socio-demographic variables determining a manager profile. The analysis is conducted based on data for 144 portfolio managers from 43 domestic equity funds operating in Poland in the period 2000-2015. The examinations are made possible by using static panel models. The obtained results indicate the existence of a relationship between managerial characteristics and risk measures, such as: standard deviation, beta coefficient, tracking error and bear-market percentile ranking. To our knowledge, it is the first paper to evaluate the investment risk of Polish mutual funds in relation to managerial characteristics.

Authors: Aina J.O. , Adeleke O.O. , Makinde V. , Egunjobi H.A. , Biere P.E.
Published: April 2020

Hydrogeological assessment of groundwater resources was carried out with a view to evaluate the potential of the aquifers to provide portable water supply and access the distribution of electrical parameters of hydrogeologic units in some areas in Odeda, Ogun State, Nigeria. A geophysical survey using vertical electrical sounding (VES) with the Schlumberger electrode array, with half-current electrode spacing (AB/2) varying from 1 to 132 m was carried out at 30 different stations in the study area. The VES data were interpreted qualitatively and quantitatively. Three-to-five sub-surface layers consisting of topsoil, weathered layer consisting of clay, sandy clay, clayey sand and sand layers, and fractured/fresh basement were delineated. Layer resistivities and thicknesses obtained on the curves within the study area showed one main aquifer type, which is the fractured basement. The longitudinal unit conductance (ranging from 0.049720 to 1.4520000 mhos) of the study area aided the protective capacity to be rated into good, moderate and weak. About 33% of the study area falls within the weak protective capacity, 57% falls within the moderate protective capacity and 10% falls within the good protective capacity.

Aim: The purpose of this paper is to review the trends in the application of geospatial technology in urban morphology data capture and studies. Methodology and Results: This review was guided by critical thinking research approach, which involves analysis of relevant literature on a phenomenon to enable to draw conclusion(s) on whether a claim is true, sometimes true, partly true or false and using methods to applied in critical thinking include broad intellectual criteria such as clarity, credibility, accuracy, precision, relevance, depth, significance and fairness. The results show that increasing urbanization and sub-optimal locations of urban amenities and utilities has resulted in many cities facing environmental, land use and socio-economic challenges. This can be mitigated by the implementation of cost-effective urban development plans and policies together with an in-depth understanding of the interactions existing between urban natural and human systems, an undertaking reliably aided by geospatial technologies notably Remote Sensing, Geographical Information Systems, Global Positioning System and Photogrammetry. Conclusion, significance, and impact study: This paper is therefore anchored on an understanding of urban morphology, factors determining its changes over time and demonstrated achievements of the utility of geospatial technology in the study of the same with policy implications for the applications of the geospatial technology in urban studies.

Aims: This study aims to assess the value sustainable development opportunity of the coral reef fisheries activities in Indonesia from the ecological, economic, and social aspect, with a case study of coral reef fisheries at the coastal area of Ternate Island, using the Sustainability Window (SuWi) approach. Methodology and Results: The data was collected from statistical data from relevant institutions and literature study, which consists of ecological, economic and social data, and analyzed using the Sustainability Window approach to determine the sustainability of the fisheries development. The result shows that the Sustainability Window of the coral reef fisheries in the research area tends to move towards sustainable development, where the national policy in catch fisheries management has an impact on the sustainable development and management of coral reef fisheries at the coastal area of Ternate Island. Conclusion, significance and impact study: The Sustainability Window of coral reef fisheries at the coastal area of Ternate Island tends to move towards sustainable processes, with the width of sustainability window that not too narrow to the coral reef fisheries activities at the provincial and national levels. This condition attaches strings to a precautionary approach in policy decision for the management process, and consideration to the effect that can result from the development policy, both at the provincial and national level. The use of Sustainability Windows approach can provide a new simple way for assessing whether the development has been towards a more sustainable direction or not.

The process of aerobic composting the slaughterhouse (SH) solid waste generate ammonia emissions. Aim: The objective of this research to study the ability of the adsorbent to use zeolite to reduce ammonia gas emissions during the composting process of SH solid waste. Methodology and Results: Reduction of ammonia emission is conducted during the aerobic composting process which is 50 days. The raw material composition of the composting process used was 100% rumen contents, 60% rumen contents: 40% straw, 50% rumen contents: 50% straw, and 40% rumen contents: 60% straw. Zeolite used in the form of granular size 100 mesh. The result of the research showed that the level of release of ammonia gas emissions during the composting process could be reduced by zeolite. Conclusion, significance, and impact study: The efficiency of reducing ammonia gas emissions using zeolite adsorbents in the composting process of SH solid waste ranges from 98.09 - 99.40% on average. Zeolite is an adsorbent that has high adsorption power because it has many pores and has a high ion exchange high capacity and serves as an absorbent cation that can cause environmental pollution.
Metabolomics Analysis Reveals Both Plant Variety and Choice of Hormone Treatment Modulate Vinca Alkaloid Production in Catharanthus Roseus.

The medicinal plant Catharanthus roseusproduces numerous secondary metabolites of interest for the treatment of many diseases—most notably for the terpene indole alkaloid (TIA) vinblastine, which is used in the treatment of leukemia and Hodgkin’s lymphoma. Historically, methyl jasmonate (MeJA) has been used to induce TIA production, but in the past, this has only been investigated in either whole seedlings, cell culture, or hairy root culture. In this work, we investigate the induction capabilities of MeJA and ethylene, a different phytohormone, in both the shoots and roots of two varieties of C. roseus. Using LCMS and RT-qPCR, we demonstrate the importance of variety selection, as we observe markedly different induction patterns of important TIA precursor compounds. Additionally, both phytohormone choice and concentration have significant effects on TIA biosynthesis. Finally, our study suggests that several early-induction pathway steps as well as pathway-specific genes are likely to be transcriptionally regulated. Our findings highlight the need for a complete set of ’omics resources in commonly used C. roseus varieties.

We report the comparison of two small-molecule collections synthesized at KU at two different eras. We used a machine learning tool to classify the compounds in these collections by their predicted protein targets. The analyses shine light on the evolution of medicinal chemistry research at the University of Kansas, and reveal several new associations between compounds and protein targets.
Molecular Docking Studies of N-Acetyl Cysteine, Zinc Acetyl Cysteine and Niclosamide on SARS Cov 2 Protease and Its Comparison with Hydroxychloroquine
Authors: Guthappa Roopa
Published: April 2020

To Respected Sir/Madam Chemarxiv Respected Sir/Madam Sub: submission of preprint of article to Chemarxiv for online publication. I am herewith submitting the preprint of an article entitled “Molecular docking studies of N-acetyl cysteine, zinc acetyl cysteine and niclosamide on SARS Cov 2 protease and its comparison with hydroxychloroquine” for possible publication in “Chemarxiv”. In this article, we have evaluated the binding abilities of N-acetyl cysteine, zinc acetyl cysteine and niclosamide (antiviral drug) with SARS-COV-2 protease. All the four compounds investigated are effective and selectively bind to active sites of main protease. N-acetyl cysteine being a derivative of cysteine interacts with Cys-145, His-163, Gly-143 of COV-2 protease, zinc acetyl cysteine binds to Gly-143, Ser-144, Cys-145, Glu-166 of COV-2 protease and niclosamide bind to Glu-166, Cys-145, His 41 of main protease. The data has been compared with hydroxychloroquine which effectively binds to Cys-145, Glu-166, Arg-188. The binding affinities of N-acetyl cysteine, zinc-acetyl cysteine and niclosamide are -4.24, -4.29 and -7.5 kcal mol-1 while for hydroxychloroquine it is -6.66 kcal mol-1. Niclosamide with its lowest binding energy interacts with His-41 and Cys-145 which may be the first molecule to show such binding interaction. The results indicate that N-acetyl cysteine, zinc-acetyl cysteine and niclosamide can also be explored for the treatment for SARS COV-2 as an alternative for hydroxychloroquine. I hope that the manuscript will full fill the journal’s requirements and will get accepted for publication. Thanking you With regards Roopa Guthappa roopag81@yahoo.com
[FeFe]-Hydrogenase Maturation: H-Cluster Assembly Intermediates Tracked by Electron Paramagnetic Resonance, Infrared, and X-Ray Absorption Spectroscopy

[FeFe]-hydrogenase enzymes employ a unique organometallic cofactor for efficient and reversible hydrogen conversion. This so-called H-cluster consists of a [4Fe-4S] cubane cysteine-linked to a diiron complex coordinated by carbon monoxide and cyanide ligands and an azadithiolate ligand (adt = NH(CH2S)2). [FeFe]-hydrogenase apo-protein binding only the [4Fe-4S] sub-complex can be fully activated in vitro by the addition of a synthetic diiron site precursor complex ([2Fe]adt,). Elucidation of the mechanism of cofactor assembly will aid in the design of improved hydrogen processing synthetic catalysts. We combined in situ electron paramagnetic resonance, Fourier-transform infrared, and X-ray absorption spectroscopy to characterize intermediates of H-cluster assembly as initiated by mixing of the apo-protein (HydA1) from the green alga Chlamydomonas reinhardtii with [2Fe]adt. The three methods consistently show rapid formation of a complete H-cluster in the oxidized, CO-inhibited state (Hox-CO) already within seconds after the mixing. Moreover, FTIR spectroscopy support a model in which Hox-CO formation is preceded by a short-lived Hred´-CO like intermediate. Accumulation of Hox-CO was followed by CO release resulting in the slower conversion to the catalytically active state (Hox) as well as formation of reduced states of the H-cluster.

Lipid droplets (LDs) are metabolic organelles that store neutral lipids and dynamically respond to changes in energy availability by accumulating or mobilizing triacylglycerols (TAGs). How the plastic behavior of LDs is regulated is poorly understood. Hereditary spastic paraplegia is a central motor axonopathy predominantly caused by mutations in SPAST, encoding the microtubule-severing protein spastin. The spastin-M1 isoform localizes to nascent LDs in mammalian cells; however, the mechanistic significance of this targeting is not fully explained. Here, we show that tightly controlled levels of spastin-M1 are required to inhibit LD biogenesis and TAG accumulation. Spastin-M1 maintains the morphogenesis of the ER when TAG synthesis is prevented, independent from microtubule binding. Moreover, spastin plays a microtubule-dependent role in mediating the dispersion of LDs from the ER upon glucose starvation. Our results reveal a dual role of spastin to shape ER tubules and to regulate LD movement along microtubules, opening new perspectives for the pathogenesis of hereditary spastic paraplegia.
