Authors: Munar Samboní Andrés Mauricio , Rodríguez Carlosama Adalberto , Muñoz España Jorge Luis 
Published: January 2022

Contextualización: El cambio climático y las actividades antrópicas sobre los recursos naturales se constituyen como los principales causantes de la pérdida de biodiversidad y la redistribución de las especies.
Vacío de conocimiento: Sin embargo, los efectos a nivel de comunidades y ecosistemas, así como los impactos en cultivos agrícolas en escala regional, son poco estudiados. Los modelos de distribución de especies se han convertido, por lo tanto, en valiosas herramientas para la predicción de áreas potencialmente aptas para especies cultivables, su gestión y planificación.
Propósito: Este estudio consistió en la predicción de potenciales áreas cultivables de maracuyá (Passiflora edulis var. flavicarpa Degener), granadilla (Passiflora ligularis Juss), y cholupa (Passiflora maliformis L.) en una región tropical, a través del modelo MaxEnt, en escenarios de cambio climático.
Metodología: Se utilizaron como datos de entrada (para el modelo MaxEnt) registros de presencia de las especies analizadas, obtenidos a partir de sus coordenadas geográficas. En total, fueron usados 141 registros de presencia de maracuyá, 256 registros de granadilla y 40 registros de cholupa, así como 12 variables bioclimáticas para las proyecciones actuales y futuras en los periodos 2050 y 2070, considerando así dos escenarios RCPs (Representative Concentration Pathways) del Coupled Model Intercomparison Project (CMIP5) (RCP 4.5 y RCP 8.5).
Resultados y conclusiones: Los resultados revelan que las potenciales áreas cultivables para las especies analizadas podrían pronosticarse a través de MaxEnt utilizando registros de presencia en campo y variables bioclimáticas. Así mismo, las simulaciones indicaron que las áreas de ocurrencia potencial para las especies analizadas podrían disminuir en el futuro dependiendo de los escenarios climáticos (RCP 4.5 y RCP 8.5) para los periodos 2050 y 2070. Para los cultivos de maracuyá, granadilla y cholupa, las mayores reducciones en las áreas de ocurrencia potencial corresponden al 23 %, 25 % y 31 % respectivamente, y se presentarían en el período 2070 en un escenario pesimista (RCP 8.5). Este es el primer estudio que pronostica las potenciales áreas cultivables de pasifloras utilizando el modelo Maxent y escenarios de cambio climático en escala regional en una región tropical. El abordaje propuesto puede proveer importantes herramientas para la gestión y aprovechamiento sostenible de las especies estudiadas.
Theoretical and Practical Guidance for Incorporating Auditor-Client Communication in Experimental Research
Authors: Hatfield Richard C. , Saiewitz Aaron 
Published: January 2022

SUMMARY
In this paper, we provide theoretical and practical guidance on experimental design choices when incorporating auditor-client communication in audit research. We structure our discussion around Social Presence Theory, noting how elements of social presence impact theoretical predictions and the related experimental design. We then compare non-interactive, highly controlled paper/computer-based studies with studies that involve automated interaction, interaction with an actor, or interaction between participants. We provide a discussion of best practices and pitfalls related to these different experimental design choices, including theoretical and logistical considerations, as well as recent innovations in this area. While our methodological discussion is nested in auditor-client communication research, these methods and logistical considerations are applicable to most accounting experiments designed to address research questions steeped in social psychology (i.e., contexts of human interaction).

This review provided a detailed overview of the different synthesis and characterization methods of polymeric nanoparticles. Nanoparticles are defined as solid and colloidal particles of macromolecular substances ranging in size under 100 nm. Different types of nanoparticles are used in many biological fields (bio-sensing, biological separation, molecular imaging, anticancer therapy, etc.). The new features and functions provided by nano dimensions are largely different from their bulk forms. High volume/surface ratio, improved resolution and multifunctional capability make these materials gain many new features.

Every year hundreds of serious accidents and catastrophic are accompanied by mining sector services as disaster, flooding, and demolition. To reduce the severity of the results such as high death numbers, lost communication inner and out mining, we have to find an easy way to improve communication means during that problems. In this paper, we reach out to fabricate durable, flexible, and wearable chaps, in addition to an easier carrier with highly efficient receiving and sending a signal at 2.4 GHz broad wide band. By doping a bunch of unique conductive metals (silver, copper, and gallium indium alloy) assembled on Graphene, its integration inside Polydimethylsiloxane to be future applicable antenna. Furthermore, we studied the physical and electric properties of a composite including Electrochemical Impedance properties (EIS), cyclic voltammetry (CV), and its thermal stability chip (DSC), as well as, using Transmission electron microscopy (TEM), and, scanning electron microscopy (SEM) techniques to clarify the surface morphology of fabricated materials. In addition to various measurements had been carried out such as Ultraviolet-visible, inductively coupled plasma (ICP) spectroscopy, and Energy-dispersive X-ray spectroscopy (EDX) to reinforce and elucidate the solid-state of ions inside fabricated Antenna. On the other hand, throughout stress-strain for the stretchability of fabricated is expanded to 30% of its original length, in addition to thermal stability reached to 485°C compared to pure PDMS substrate, with enhancing electric conductivity of composite ship.

Published: January 2022

Abstract
The paper presents the computational studies on the microstructure of WC-Co-Cr coatings deposited by High Velocity Oxy Fuel spraying (HVOF). The study covers the porosity assessment according to ASTM E2109-01 standard, carried out in ImageJ software, in terms of volume porosity, size and shape of the pores. The evaluation was preceded by scanning electron microscope (SEM) observations at magnifications of 2000x and 5000x. Additionally, topography analysis has been performed by confocal laser scanning microscope (CLSM), and the surface roughness Ra was evaluated by the contact method with use of a stylus profilometer. Finally, the influence of porosity was observed for coatings microhardness HV0.3. According to the results, the total closed porosity was found to be in the range of 5.01 vol.% and 5.38 vol.%. The dominated pores in the coatings were of size 0.1-1.0 μm. Studies showed that HVOF process enabled deposition of dense coatings, characterized by homogenous distribution of pores and low roughness.

Published: January 2022

Abstract
The paper presents the results of experimental research aimed at determining the possibilities of strengthening structural adhesive joints. Techniques to improve the strength of adhesive joints was to make holes in the front part of the adherends in order to make the joint locally more flexible in the area of stress concentration at the joint edges. The tests were carried out for the lap joints of EN AW-2024-T3 aluminum alloy sheets, which were bonded with Loctite EA3430 epoxy adhesive. Static tests were carried out on the basis of the tensile/shear test. It has been shown that the applied structural modifications allow for an increase in the strength of the joint, in the best variant, an increase in strength of 14.5% was obtained. In addition, it has been shown that making holes in the adherends allows to reduce the spread of strength results.
Exploring identity positionings in scholarly texts on management
Authors: Lehman Iga 
Published: January 2022

Abstract

Background and research aims
Since scholarly texts on management have been criticised as being no longer effective in communicating today's changing sociocultural, disciplinary, and practical contexts, my purpose in this paper is to conceptualise the identity options management authors can assume to communicate disciplinary knowledge and beliefs.

Theoretical perspective
The theoretical perspectives involved in this analysis include selected aspects of Harré and van Langenhove's (1999) positioning theory that I linked with my model of writer identity as a trichotomy of selves (individual self, collective self, depersonalised self), textually conveyed in the three types of voice (Lehman, 2018; Lehman and Sułkowski, 2020).

Key findings
Based on this conceptual framework, specific advice is provided as to how academics can create a reader-inclusive or authoritative writer persona in their texts. In doing so, I support the recent efforts in Critical Management Studies (CMS) to ‘write differently’ in order to address the aesthetic, moral, and political concerns of writing in the field.
