Development and Psychometric Evaluation of the Professional Integration Factors Retention Strategies Survey
Authors: Gamble Beth
Published: November 2020

Background and Purpose

Nursing students experience higher attrition rates than average college students due to the academic rigor of nursing programs. This study examined psychometric properties of the Professional Integration Factors Retention Strategies Survey (PIF-RSS), which measured constructs of faculty advisement and helpfulness, professional events, memberships, encouragement by friends in class, peer mentoring-tutoring, and enrichment programs.

Methods

The PIF-RSS survey was distributed to deans, directors, and program coordinators of traditional Bachelor's in Nursing programs.

Results

Following exploratory factor analysis, 47 items aligned within a 5-factor solution were retained. Reliability of the total instrument was .90.

Conclusions

This study provides preliminary evidence of the psychometric properties of the PIF-RSS instrument. Additional studies are recommended to further examine instrument psychometric properties for different program types and populations.

Authors: McMullan Susan P. , Raju Dheeraj , Patrician Patricia
Published: November 2020

Background and Purpose

In a previous study, the CRNA Workload Perception Scale (CWPS) was developed. The purpose of this study was to investigate the psychometrics of the CWPS.

Methods

The CWPS was tested in a population of CRNAs. This study was conducted in two phases. Phase I consisted of classical psychometrics; the 12-item instrument was piloted in a sample of 265 CRNAs. Phase II consisted of qualitative analysis to provide feedback on items that did not perform well.

Results

Phase I: Instrument demonstrated good reliability (r = .77). Parametric and nonparametric analysis indicated 6 of 12 items were good fit to measure perception of workload.

Phase II

Qualitative analysis resulted in refinement of four items, addition of one item, and elimination of two items.

Conclusions

A revised 11-item CWPS was developed.
Validating Factors That Influence Student Nurse Intention Regarding Perioperative Nursing
Authors: Kapaale Chaluza C.
Published: November 2020

Background

Failure to effectively recruit Newly Graduated Nurses (NGN) to perioperative nursing in the face of an anticipated nursing shortage will adversely impact patient outcomes. Development of interventions that address the recruitment problem is hampered by lack of a comprehensive understanding of factors that influence Student Nurse Intention (SNI) regarding perioperative nursing.

Purpose

This descriptive quantitative study aims to test a Theory of Planned Behavior (TPB) questionnaire and validate factors that influence SNI.

Method

Quantitative sequence of exploratory sequential design. Item analysis, and principal component analysis of data are completed.

Results

The instrument demonstrated satisfactory psychometrics. Immediate exposure or immersion, affirmation by nurse managers, and availability of positions were the most influential attitudinal, normative, and control beliefs respectively. Generational values have some influence on intention to choose perioperative nursing.

Conclusion

A TPB questionnaire is useful for measuring factors that influence SNI.
Evaluation of the Psychometric Properties of Relational Insights 360 Among Baccalaureate Nursing Students With the Use of Standardized Patients
Authors: Zimmer Mary Ann
Published: November 2020

Background and Purpose

The purpose of this study was to evaluate reliability and validity of the relational competency assessment instrument, Relational Insights 360 (RI-360) (Koloroutis & Trout, 2012), among 104 baccalaureate nursing students and 10 standardized patients (SPs) upon completion of a communication simulation.

Methods

The reliability of the RI-360 was determined by Cronbach's alpha coefficient. Interrater reliability of the RI-360 was measured between the SPs and the primary investigator with percentages. Factor analysis was run to evaluate the construct validity.

Results

The RI-360 was internally consistent with an alpha coefficient of 0.93. Interrater reliability for all items on the RI-360 was 42% between students' scores and SPs' scores and 38.9% between the Primary Investigator's scores and SPs' scores. Exploratory factor analysis showed that factor loadings ranged from 0.29 to 0.84.

Conclusions

The RI-360 appears to be a valid and reliable scale for use in measuring relational competency among nursing students and SPs.

Authors:   , Zegarra Lizana Paolo André , Ramos Orosco Elizabeth Jeanette
Published: November 2020

Objetivo: Evaluar la asociación entre porcentaje de grasa corporal (%GC) elevada y la prevalencia de resistencia a la insulina (RI) en población adulta con Índice de masa corporal (IMC) en rango normal. Metodología: Realizamos un estudio transversal analítico. Los participantes se atendieron de forma ambulatoria entre los años 2012 y 2016 en una clínica privada en Lima Perú, entre 18 y 60 años con IMC entre 19 y 24,9 kg/m2. Definimos %GC elevado si el valor era mayor de 25% en varones y 30% en mujeres; y RI con el punto de corte de HOMA-RI en el percentil 75. Realizamos un modelo lineal generalizado de la familia de Poisson (crudo y ajustado) con errores estándares robustos para evaluar la asociación entre %GC y RI. Reportamos como medida de asociación la razón de prevalencias (RP) con sus respectivos intervalos de confianza (IC) al 95%. Resultados: Incluimos 284 participantes, el promedio de edad fue 33,77 ± 10,86 (DE) años y el porcentaje de mujeres fue 88,1%. La prevalencia de %GC elevado fue 71,13% y la prevalencia de RI fue 25%. Encontramos asociación entre el %GC y RI (RP= 3,172; IC 95% 1,456 - 6,907). Conclusiones: El porcentaje de grasa corporal parece ser un buen indicador de RI en poblaciones con IMC normal y sin comorbilidades endocrinológicas. Se recomiendan estudios prospectivos longitudinales para corroborar nuestros hallazgos.
Phytodiversité et services écosystémiques associés aux plantations d’alignement des rues aménagées de la ville de Grand-Popo au Bénin

Published: November 2020

L’importance de la végétation urbaine dans la production des services écosystémiques en général est largement démontrée. Au Bénin, en plus des avantages socio-écologiques attribués aux arbres d’alignement, ils contribuent considérablement à la fourniture de services d’approvisionnement et socioculturels, du fait de leur utilisation locale par les populations. Le présent travail évalue la contribution de la diversité floristique des rues dans la fourniture des biens et services aux habitants de la ville de Grand-Popo au Bénin. La démarche méthodologique adoptée a permis de dénombrer les arbres plantés sur dix kilomètres de rues aménagées et de questionner 164 ménages sur les services rendus par ces arbres. Les paramètres de diversité sont calculés pour apprécier la phytodiversité des axes routiers. La matrice des formes d’usage des organes est établie, en correspondance avec les catégories de services écosystémiques existantes. Les résultats obtenus révèlent 540 arbres, répartis en 26 espèces et 17 familles le long des principaux axes routiers de la ville. L’indice moyen de diversité de Shannon (3,61 ± 0,14 bits) et l’équitabilité de Pielou (0,76 ± 0,06) démontrent un phénomène de dominance de quelques espèces, dont la plus représentative est Cocos nucifera avec 20 % de l’effectif total des individus. Les arbres d’alignement ont été plantés majoritairement par les autorités pour leur ombrage, l’esthétique du paysage et la séquestration de carbone. Alors qu’en pratique, de par leur usage et l’introduction de nouvelles espèces utiles par les populations riveraines, les plantations fournissent plus de neuf services écosystémiques avec une grande importance accordée à la fourniture de l’ombrage et de l’alimentation. Pour une valorisation de la foresterie urbaine, la prise en compte de ces informations pourrait servir à promouvoir les services écosystémiques sans compromettre la viabilité des arbres en plantations dans la ville.
Control over decision-making in eight major oil palm plantation companies in Malaysia
Authors: KAMARUDDIN Norfaryanti
Published: November 2020

Southeast Asia's mosaics of agricultural and tropical forest landscapes have been significantly shaped by the advance of industrial plantations from colonial times to the present. Controversies over deforestation and oil palm sustainability have emerged in this context. Significant land use changes have been made by industrial plantation companies, which have diversified their activities to sectors ranging from automobiles to banking and telecoms to become corporate giants.

The solutions proposed today to curb deforestation for oil palm plantations consist of sectoral market tools such as trade bans, regulations or certification schemes that are supposed to influence the economic decisions of private companies. However, oil palm corporations are so diversified and deeply embedded in national economies that many other factors could influence their corporate decision-making. Studies since Porter and Laporta suggest that the structure of the financial network of company shareholders may have more influence on corporate decisions than the market itself, in other words that the nature of company ownership (government versus private sector) is the essential driver in corporate decision-making.

This thesis explores how these structural drivers play out in major oil palm corporations.  Using network analysis, we quantified and analysed shareholdings in the main oil palm corporations in Malaysia. We gathered data on 4,331 shareholdings at ten different levels. The study describes the financial topologies and compares them with the nature of company ownership and with measurable decision-making processes, such as structural control and decision loads.

We found that decision-making was not influenced by the nature of ownership but was very much influenced by the financial structure of the corporations. We also found that decision loads and structural control seem to predict a structural flexibility which is intrinsic to these corporations.

The implications of these findings could help to rethink the political governance of deforestation and open up a new field of research concerned with describing and analysing the deep financial structures that govern the behaviour of corporations. Firstly, understanding the financial forces that shape plantation companies is critical to oil palm and forest sustainability. Secondly, we can now identify and prioritize the most resilient corporations with a view to developing sustainable practices for the long term.
Structure et dynamique des espèces ligneuses des forêts-galeries des rivières et ruisseaux du secteur sud-soudanien du Burkina Faso

Published: November 2020

Les forêts-galeries du Burkina Faso sont menacées de disparition sous l’effet des actions anthropiques et du changement climatique. Elles survivent sous une forme fragmentée dans le secteur sud-soudanien du Burkina Faso. L’objectif de cette étude est, d’une part, de décrire les caractéristiques structurales des groupements végétaux de deux types de cours d’eau, à savoir les rivières et les ruisseaux, et, d’autre part, de déterminer la structure démographique des espèces dominantes afin d’apprécier leur dynamique. Les données ont été collectées suivant un inventaire systématique dans des placettes de 1 000 m² pour la strate adulte et 100 m² pour la régénération suivant des transects perpendiculaires au cours d’eau principal. Cette étude a permis de recenser 127 espèces réparties en 98 genres et 47 familles. Les densités des groupements végétaux varient significativement entre elles, avec les plus fortes valeurs au niveau des groupements des rivières. Les surfaces terrières varient aussi significativement entre elles avec les plus fortes valeurs rencontrées au niveau des groupements des ruisseaux. Les espèces dominantes des groupements des rivières ont en général une structure stable due probablement à leur situation dans des aires protégées et à leur biologie. Au niveau des groupements des ruisseaux, les espèces dominantes ont des structures déséquilibrées avec dominance d’individus de gros diamètre. Les espèces dominantes dans la strate adulte n’ont pas une bonne régénération dans la strate juvénile. De cette étude, il ressort que le type de cours d’eau semble influencer la structure des groupements. Les espèces dominantes dans la strate adulte n’ont pas forcément une bonne régénération. Des mesures de protection s’appuyant sur ces résultats devraient être envisagées en faveur des forêts-galeries du secteur sud-soudanien.
Las mujeres como clase social: origen y desarrollo de una teoría. De los Colectivos Feministas al Partido Feminista de España (1975-1983)
Authors: Gahete Muñoz Soraya
Published: November 2020

El feminismo español de los años setenta y ochenta se inscribió dentro de las tendencias feministas desarrolladas en la llamada segunda ola. Entre estas tendencias podemos señalar el feminismo materialista, es decir, aquel que basándose en los postulados marxistas elaboró su propia teoría sobre el origen de la explotación de las mujeres y desarrolló distintas tácticas para subvertir la realidad. En España, esta tendencia fue representada, en un primer momento, por los llamados Colectivos Homologados del Estado Español y, posteriormente, por el Partido Feminista de España que desarrolló mucho más la idea anunciada por los Colectivos: la mujer como clase social. Al igual que ocurrió a nivel internacional, la formulación de esta idea ocasionó distintos debates entre sus detractoras, especialmente, en aquellas vinculadas al feminismo marxista para quienes la teoría marxista no podía extrapolarse a la situación de las mujeres porque la realidad de estas y de la clase obrera era totalmente distinta. Planteamiento que no compartieron las organizaciones citadas anteriormente y que intentaron demostrar que las mujeres forman una clase social al estar insertas dentro del modo de producción doméstico.

sectors and replaced the conventional materials. There durability has made it non biodegradable
and has also affected the environment due to its large production according to the need of the
growing population. The use of biological means to degrade these plastics has been extensively
studied by using different microorganisms collected from mainly contaminated sites. This paper
discuss about the different screening methods for the detection of plastic degrading
microorganisms. The different enzymes synthesized by microorganisms degrade different types

Compaction Characteristics of Swelling Soil Stabilized with
Bottom Ash and Geogrid
Authors: Rajakumar C. , Rama Rao P. Kodanda
Published: November 2020

This paper brings out the results of experimental work carried out in the laboratory to
evaluate the effectiveness of using bottom ash with geogrid for soil stabilization by studying the
compaction and strength characteristics for use as a sub-grade material. Bottom ash is a waste
material which is obtained from thermal power plants. This waste imposes hazardous effect on
environment and human health. This material cannot be disposed of properly and their disposal
is not economical. Utilization by exploiting their inherent properties is the one of the way to
solve the above stated problem. The effect of mixing different proportions of bottom ash with
geogrid in clayey soil on compaction, UCS and California bearing ratio have been studied in
this study.
Slope Stability Analysis of Kattery Watershed in Nilgiris
District
Authors: Rajakumar C. , Rama Rao P. Kodanda
Published: November 2020

The slope stability analysis is always under severe threats in many parts of nilgiris
district, causing disruption, loss of human life and economy. The stability of slopes depends on
the soil shear strength parameters such as Cohesion, Angle of internal friction, Unit weight of
soil and Slope geometry. The stability of a slope is measured by its factor of safety using
geometric and shear strength parameter based on infinite slopes. In this research, investigation
was carried out at 5 locations in Kattery watershed in nilgiris district. The factor of safety of the
slope determined by Mohr Coulomb theory based on shear strength parameter calculated from
direct shear test which is a conventional procedure for this study. Artificial.
Neural Network (ANN) Model is used to predict the factor of safety. The input parameters for
the (ANN) are chosen as Cohesion, Angle of internal friction, Density and Slope angle and the
factor of safety as output. The results obtained in ANN method were compared with that of
conventional method and observed a good agreement between these two methods.
Effective Removal of Toxic Methylene Blue Dye from Textile
Industry Wastewater using Graphene Oxide- Silica [GO-Si]
Nano Composite Adsorbent
Authors: Pachiyappan Jayakaran , Gnanasundaram Nirmala , Lakshmana Rao Govindarajan
Published: November 2020

Textile companies release wastewater containing lots of colors including Methylene
Blue (MB) dye. Those colors are harrmful for human well being. Various procedures have
been utilized to expel the color from industrial wastewater. Out of different methods used in
practice, adsorption was observed to be exceptionally successful and effective. The reason
behind the especiality is when nanocomposites are utilized as an adsorbent, as it has a better
adsorption limit, selectivity, and solidness than nanoparticles. In this research, a peculiar
synthesis of adsorbent Graphene Oxide Silica [GO-Si] is carried out and it is used to remove
methylene blue dye from texile industry wastewater. Analysing the performance of MB dye
removal from the waste water using this adsorbent seems to be more effective. Various studies
have been carried out for successful analysis of the performance such as adsorption isotherm
study, Freundlich and Langmuir analysis. In addition the adsorption process was well explained
by a pseudo-second-order kinetics models.

En uno de los paneles de la reciente exposición, Videojuegos. Los dos lados de la pantalla (Fundación Telefónica, 2019), se podía leer que "el videojuego está internado en multitud de ámbitos, generando un alto impacto en la cultura". Como expresión visual de la modernidad, entre sus preocupaciones se encuentra no solo divertir al gran público, sino ser un instrumento de concienciación y manifestación de la problemática de la sociedad en la que nace. A lo largo del presente texto, y a partir del análisis de la obra Emporium (2017), queremos mostrar como la soledad, el suicidio y el desarraigo toman visibilidad a través de narrativas que revelan las preocupaciones más íntimas del ser humano, nacidas en esta ocasión a partir de la propia tragedia personal sufrida por el autor. Pequeñas obras, de no más de 45 minutos, combinaciones melódicas de imágenes y texto, en las que asoman como breves pinceladas introspectivas algunas de las principales preocupaciones de la contemporaneidad, tales como el suicidio.
Democracia, deslegitimación y cambio social: el videojuego como dispositivo de cuestionamiento político
Authors: Sequeiros Bruna Costán , Puente Bienvenido Héctor
Published: November 2020

Tradicionalmente, el Estado ha organizado una serie de instituciones que garantizan el aprendizaje y adoctrinamiento en el sistema. Pero las democracias llevan en crisis de legitimidad desde la crisis económica de 2007/08, una deslegitimación que crece a medida que las TICs llevan nuevos modelos políticos e ideas de un lado a otro del mundo. Un entorno digital que transporta valores culturales a través de todo los productos mediáticos, siendo los videojuegos uno de los más importantes hoy en día. Esto los ha convertido en un campo de aprendizaje y experimentación que ha llevado a la aparición de espacios políticos en los videojuegos (como manifestaciones o escenarios de lucha y activismo), exigencias a las compañías desarrolladoras, estructuras de relaciones más horizontales y muchos espacios de discusión identitaria (como el género). Aprendizajes que los ciudadanos obtienen en su tiempo de ocio pero que no se olvidan cuando desconectan de sus juegos, sino que quedan insertados en sus identidades.

La memoria indolora del videojuego de historia
Authors: Venegas Ramos Alberto
Published: November 2020

La formación y la consolidación de la identidad nacional y de determinadas comunidades descansan sobre la memoria y el recuerdo del pasado. En la actualidad países como Estados Unidos, España, Polonia, Alemania, Francia o la República Checa mantienen una disputa memorística en su interior que provoca problemas sociales relacionados con las políticas y las leyes de la memoria. Sirva de ejemplo el caso de España y el caso de la Ley 52/2007, de 26 de diciembre, por la que se reconocen y amplían derechos y se establecen medidas a favor de quienes padecieron persecución o violencia durante la guerra civil y la dictadura conocida popularmente como Ley de Memoria Histórica que tantos debates y enfrentamientos ha generado en la política nacional. El videojuego es un medio que puede aportar, o no, a la cultura de la conmemoración. Para evidenciar la afirmación anterior analizaremos distintos videojuegos de historia que ayudan a entender el medio como parte de esa cultura de la conmemoración construyendo el pasado y ligándolo al presente y otros que no ayudan a dicha conmemoración y reconstruyen el pasado bajo el formato hiperespectáculo.

How Toxic indeed is Oxymetazoline? Collection and Comparison of Toxicological Data of Pharmacologically Active Imidazoline Derivatives
Authors: Strey Karsten
Published: November 2020

Imidazoline derivatives, such as xylometazoline, naphazoline, tetryzoline, tramazoline or oxymetazoline play an important pharmacological role as nasal drops in the symptomatic treatment of rhinitis. When comparing the toxicological data of these substances, it is noticeable that Oxymetazoline has an LD50 value which is two orders of magnitude lower than all other imidazoline derivatives. Thus, ten vials of commercially available oxymetazoline nasal drops already contain a lethal amount. An explanation for this unusually high toxicity has not yet been found.
A New Method of Regulating the Load on the Shaft Lining in Sections Passing Through the Salt Rock Mass
Authors: Kamiński Paweł
Published: November 2020

Rock salt is characterised by specific geomechanical and rheological properties. The layers of rock salt which occur on the depths over 900 m contribute to problems with shaft lining deformation. Methods of shaft lining protection used so far (e.g. in Sieroszowice mine) have not been effective enough. The research presents a patented and copyright protected concept of constructing a shaft lining that goes through rock masses having strong rheological properties and being susceptible to leaching. In the case of salt layers, especially at significant depths the relative convergence of the heading contour may amount to 40 ‰/year. That results in the fact that any other method of securing the shaft lining, e.g. by making it flexible, will not be sufficient to ensure the stability of the shaft reinforcement geometry. In the new shaft lining concept the excessive rock creep into the outbreak inside the shaft diameter will be removed by local and controlled leaching of the shaft cheeks by means of fresh water directed through a porous medium at the contact layer behind the watertight tubing lining. The article presents the methodology of performing tests on a special device and the test results.
Are They Really Trying to Save Their Buddy? The Anthropomorphism of Animal Epimeletic Behaviours
Authors: Sueur Cedric , Forin-Wiart Marie-Amélie , Pelé Marie
Published: November 2020

Anthropomorphism is a natural tendency in humans, but it is also influenced by many characteristics of the observer (the human) and the observed entity (here, the animal species). This study asked participants to complete an online questionnaire about three videos showing epimeletic behaviours in three animal species. In the videos, an individual (a sparrow, an elephant and a macaque, respectively) displayed behaviours towards an inanimate conspecific that suddenly regained consciousness at the end of the footage. A fourth video showed a robot dog being kicked by an engineer to demonstrate its stability. Each video was followed by a series of questions designed to evaluate the degree of anthropomorphism of participants, from mentaphobia (no attribution of intentions and beliefs, whatever the animal species) to full anthropomorphism (full attribution of intentions and beliefs by animals, to the same extent as in humans) and to measure how far the participants had correctly assessed each situation in terms of biological reality (current scientific knowledge of each species). There is a negative correlation (about 61%) between the mental states attributed to animals by humans to animals and the real capability of animals. The heterogeneity of responses proved that humans display different forms of anthropomorphism, from rejecting all emotional or intentional states in animals to considering animals to show the same intentions as humans. However, the scores participants attributed to animals differed according to the species shown in the video and to human sociodemographic characteristics. Understanding the potential usefulness of these factors can lead to better relationships with animals and encourage a positive view of human-robot interactions. Indeed, reflective or critical anthropomorphism can increase our humanity.
Self-Perception of Digital Competence of Educators During the COVID-19 Pandemic: A Cross-Analysis of Different Educational Stages
Authors: Portillo Javier , Garay Urtza , Tejada Eneko , Bilbao Naiara
Published: November 2020

The objective of this research is to measure the perception that teachers had about their own performance when they were forced to carry out an Emergency Remote Teaching due to the COVID-19 pandemic. A questionnaire was provided to teachers of every educational stage in the Basque Country (Pre-school, Primary and Secondary Education, Professional Training and Higher Education) obtaining a total of 4,586 responses. The statistical analysis of the data shows that the greatest difficulties reported by educators are shortcomings in their training in digital skills, which has made them perceive more workload during the lockdown and negative emotions. Another finding is the existing digital divide between teachers based on their gender, age and type of school. A further worrying result is the lower technological competence in lower educational levels, which are the most vulnerable in remote teaching. These results invite us to reflect on the measures to be taken to improve equity, social justice and resilience of the educational system, which align with some of the Sustainable Development Goals.
Asymmetric Dependence between Oil Prices and Maritime Freight Rates: A Time-Varying Copula Approach
Authors: Choi Ki-Hong , Yoon Seong-Min
Published: November 2020

Changes in crude oil price affect the shipping freight market in three different channels. This study explores the dependence structure between oil prices and maritime freight rates to identify the strongest channel. Therefore, it investigates the relationship between oil prices and three major maritime freight rates; the Baltic Dry Index (BDI), the Baltic Dirty Tanker Index (BDTI), and the Baltic Clean Tanker Index (BCTI). We employ the decomposition method, not studied in the existing literature. The copula approach identifies the time-varying effects and asymmetry in the tail dependence structure between oil prices and freight rates. The main results of this analysis are as follows. The decomposed components display different conditional dependence patterns, and asymmetry is revealed in the upper and lower tail dependence. In the long run, we find more dependence in extreme periods like the financial crises. In short-run fluctuations, we find the dependence increases in an economic boom. The implications of the results suggest that dependence can vary over time and may change depending on extreme events, implying that the complementary strategies of the long run and short run should be different.

The accurate assessment and monitoring of soil erosion is of great significance for guiding food production and ensuring ecological security, and it is a current research hotspot. In this paper, remote sensing and geographic information systems (GISs) are combined with the Revised Universal Soil Loss Equation (RUSLE model) to carry out research on soil erosion monitoring and make a quantitative evaluation. According to five factors, including rainfall erosivity, soil erodibility, topography, vegetation cover, crop management and water and soil conservation measures, the distribution of the soil erosion rate in Jilin Province in 2019 was mapped, and the soil erosion rate was divided into 5 levels according to the degree of erosion, including very slight, slight, moderate, severe and extremely severe erosion. Based on the segmented S-slope factor model and the unique topographical features of the study area, the relationships among the soil erosion rate, erosion risk level, erosion area, erosion amount and slope angle (θ) were systematically analysed, and a slope angle of 15° was identified as the threshold for soil erosion on sloped farmland in Jilin Province. The total soil erosion in Jilin Province was 402.14×106 t in 2019, the average soil erosion rate was 21.6 t·ha-1·a-1, and the average soil loss thickness was 1.6 mm·a-1; these values were far greater than the soil erosion rate risk threshold of 10 t ·Ha-1·a-1. Thus, the province has a strong level of soil erosion. We conclude that soil degradation is accelerating, and food production and the ecological environment will face severe challenges. It is suggested that soil erosion control should be carried out according to different types and slopes of land, with an emphasis on the management of forestland and farmland because forestland and farmland are currently the first types of land to be managed in Jilin Province. This paper aims to explore a timely, fast, efficient and convenient soil erosion monitoring and evaluation method and provide effective monitoring tools for agricultural water and soil conservation, ecological safety management and stable food production in Jilin Province and similar black soil areas.

Sporadic colorectal cancer (CRC) develops through distinct molecular events. Loss of 18q chromosome is a conspicuous event in the progression of adenoma to carcinoma. There is limited information regarding the molecular effectors of this event. Earlier, we had reported ATP8B1 as a novel gene associated with CRC. ATP8B1 belongs to the family of P-type ATPases (P4 ATPase) that primarily function to facilitate the translocation of phospholipids. In this study, we attempt to implicate ATP8B1 gene located on chromosome 18q as a tumor suppressor gene. We studied indigenous patient data and confirmed the reduced expression of ATP8B1 in tumor samples. CRC cell lines were engineered with reduced and enhanced levels of ATP8B1 which provided a tool to study its role on cancer progression. Forced reduction of ATP8B1 expression either by CRISPR/Cas9 or shRNA was associated with increased growth and proliferation of CRC cell line - HT29. In contrast, overexpression of ATP8B1 resulted in reduced growth and proliferation of SW480 cell line. We generated a network of genes that are downstream of ATP8B1. Further, we provide predicted effect of modulation of ATP8B1 levels on this network and possible effect on fatty acid metabolism related genes. These results provide evidence in support of ATP8B1 being a tumor suppressor that may affect fatty acid metabolism in CRC.

Life cycle assessment (LCA) is used frequently as a decision support tool for evaluating different design choices of products based on their environmental impacts. A life cycle usually comprises several phases of varying timespan. The amount of emissions generated from different life cycle phases of a product could be significantly different from one another. In conventional LCA, the emissions generated from the life cycle phases of a product are aggregated at the inventory analysis stage, which is then used as an input for life cycle impact assessment. However, when the emissions are aggregated, the temporal variability of inventory data is ignored, which may result in inaccurate environmental impact assessment. Besides, the conventional LCA does not consider the environmental impact of circular products with multiple use cycles. It poses difficulties in identifying the hotspots of emission-intensive activities with the potential to mislead conclusions and implications for both practice and policy. To address this issue and to analyse the embedded temporal variations in inventory data in a CE context, the paper proposes to calculate the emission intensity for each life cycle phase. It is argued that calculating and comparing emission intensity, based on the timespan and amount of emissions for individual life cycle phases, at the inventory analysis stage of LCA offers a complementary approach to the traditional aggregate emission-based LCA approach. In a circular scenario, it helps to identify significant issues during different life cycle phases and the relevant environmental performance improvement opportunities through product, business model and supply chain design.
SARS-Cov-2 Interactome with Human Ghost Proteome: A Neglected World Encompassing a Wealth of Biological Data

Conventionally, eukaryotic mRNAs were thought to be monocistronic, leading to the translation of a single protein. However, large-scale proteomics has led to a massive identification of proteins translated from mRNAs of alternative ORF (AltORFs), in addition to the predicted proteins issued from the reference ORF or from ncRNAs. These alternative proteins (AltProts) are not represented in the conventional protein databases and this “Ghost proteome” was not considered until recently. Some of these proteins are functional and there is growing evidence that they are involved in central functions in physiological and physiopathological context. Based on our experience with AltProts we have got interested in finding out their involvement in development of the SARS-CoV-2 virus, responsible for the 2020 Covid-19 outbreak. Thus, we have scrutinized the recently published data by Krogan and coworkers (2020) on the SARS-CoV-2 interactome with host cells by co-IP in the perspective of drug repurposing. The initial work has revealed the interaction between 332 human cellular RefProts with the 27 viral proteins. Re-interrogation of this data using 23 viral targets and including AltProts, followed by enrichment of the interaction networks, leads to identify 218 RefProts (in common to initial study) plus 56 AltProts involved in 93 interactions. This demonstrates the necessity to take into account the Ghost proteome for discovering new therapeutic targets and establish new therapeutic strategies. Missing the ghost proteome in the drug metabolism and pharmacokinetic (DMPK) drug development pipeline will certainly be a major limitation to the establishment of efficient therapies.
