Worlds Represented: The March of the Penguins towards the Jug of Water
Authors:   University of Antofagasta, Chile, M Rivera
Published: May 2021

In the search for an understanding of the educational processes that take place in any classroom in the country and the world and that should reflect the complexity of the entire system, this educational ethnography Represented Worlds: The March of the Penguins to the Water Jug1, portrayed for two years how they experienced the transition, from third to fourth grade, two courses of students, one, in a private (private) high school and, the other, in a municipal (public) high school in the Antofagasta commune. The hypotheses raised are related to the way in which emancipatory social representations are constructed, articulated and communicated in social mobilizations. The ethnographic study shows the co-narrative between the events that occurred, at the national level, with which the penguin movement was conceived in 2010 and what was happening in two high school classrooms in Antofagasta. This ethnographic construction constitutes a proposal for the design and analysis of various ways of collecting and making the voice of the actors visible and as a response to the complexity of recording and characterizing dynamic representations in the face of unfolding events. In the last decade we have continued to develop this approach to understand and characterize the cultural, natural and social contexts that surround education, and for this reason, we share this starting point below.
Proteomic Characterization of Protein-Protein Interactions
Authors:   Cedarville University, School of Pharmacy, USA, TD Veenstra
Published: May 2021

Identifying all the molecular components within a living cell is the first step into understanding how it functions. To further understand how a cell functions requires identifying the interactions that occur between these components. This fact is especially relevant for proteins. No protein within a human cell functions on its own without interacting with another biomolecule - usually another protein. While Protein-Protein Interactions (PPI) have historically been determined by examining a single protein per study, novel technologies developed over the past couple of decades are enabling high-throughput methods that aim to describe entire protein networks within cells. In this review, some of the technologies that have led to these developments are described along with applications of these techniques. Ultimately the goal of these technologies is to map out the entire circuitry of PPI within human cells to be able to predict the global consequences of perturbations to the cell system. This predictive capability will have major impacts on the future of both disease diagnosis and treatment.

A comparative study for the validation and advancement of two analytical approaches applied for the simultaneous determination of Mometasone Furoate (MF), Miconazole Nitrate (MIC) and Gentamicin (GM) formulated in Momenta® cream. The first approach was TLC-spectrodensitometric method, which was advanced by separating the three components on TLC aluminum plates coated with silica gel 60 F254 using chloroform: methanol: formic acid (4:0.3:0.15, v/v/v) as a mobile phase, then scanned at 254nm using Camage TLC scanner 3 operated in reflectance-absorbance mode. The second approach was the chemometric method using two models: Partial Least Squares (PLS) and Principle Component Regression Model (PCR). The proposed approaches were validated according to ICH guidelines and were applied for the determination of the ternary mixtures in their analytical mixtures and pharmaceutical preparation.

Allergens can produce sensory, neurological, and behavioral changes, especially in children diagnosed with autism and/or ADHD. Certain Traditional Chinese Medicines may reduce allergic sensitivity/inflammation and alleviate autism/ADHD like behavioral symptoms. This is a retrospective case series on two patients with allergies, gastrointestinal issues and Autism/Autismlike who had improved behaviors and allergies after a Traditional Chinese Medicine (TCM) regimen. Two patients with autism-ADHD/autism-ADHD-like behaviors and severe allergies were treated using TCM to reduce their allergies and improve their behavior. These effects were achieved when the correct concentrations and doses of a series of TCM teas and treatments were reached. TCM appeared to be safe and well tolerated. TCM significantly improved the behaviors and allergies of both patients, therefore TCM may be a potential remedy for sensory issues, neurological problems and behavioral changes associated with allergies.

Published: May 2021

The production of in vitro produced embryos of good morphological quality and viability is a prerequisite for successful assisted reproduction biotechnologies in animal breeding and human. The co-culturing system has been applied to improve preimplantation development that could subsequently resulted in successful pregnancy. There are different types of reproductive and non-reproductive cells that have been used during preimplantation development. The most well-known reproductive cells are those recovered from ovaries (cumulus and granulosa cells), oviduct and endometrium cells. While, in last decade stem cells such as mesenchymal stem cells and murine embryonic fibroblasts that originated from different tissues have been used to support early embryonic development. The positive effect co-culturing system was suggested to be due to direct mechanical cell-to-cell contact that occurred between the dividing embryos embryo and helper cells in addition to secretions of various bioactive biological components like growth factors and scavenging the deleterious byproducts that resulted from embryo metabolism. In current review, we will highlight the effects of different couture systems on embryo development and their suggested mechanisms to exert the beneficial impacts.

Published: May 2021

Herein we report a new series of bifunctional chelators (BFCs) with high affinity for amyloid β aggregates, strong binding affinity towards Cu(II), and favorable lipophilicity for potential blood-brain barrier (BBB) penetration. The alkyl carboxylate ester pendant arms enable high binding affinity towards Cu(II). The BFCs form stable 64Cu-radiolabeled complexes and exhibit favorable partition coefficient (log D) values of 0.75-0.95. Among the five compounds tested, the 64Cu-YW-1 and 64Cu-YW-13 complexes exhibit significant staining of amyloid plaques in ex vivo autoradiography studies.

Area Selective Deposition of Iron Films Using Temperature Sensitive Masking Materials and Plasma Electrons as Reducing Agents
Authors: Nadhom Hama , Yuan Yusheng , Rouf Polla , Solin Niclas , Pedersen Henrik
Published: May 2021

potential of area selective deposition (ASD) with a newly developed chemical vapor deposition method, which utilize plasma electrons as reducing agents for deposition of metal-containing films, is demonstrated using temperature sensitive polymer-based masking materials. The masking materials tested were polydimethylsiloxane (PDMS), polymethylmethacrylate (PMMA), polystyrene (PS), parafilm, Kapton tape, Scotch tape, and office paper. The masking materials were all shown to prevent film growth on the masked area of the substrate without being affected by the film deposition process. X-ray photoelectron spectroscopy analysis confirms that the films deposited consist mainly of iron, whereas no film material is found on the masked areas after mask removal. SEM analysis of films deposited with non-adhesive masking materials show that film growth extended for a small distance underneath the masking material, indicating that the CVD process with plasma electrons as reducing agents is not a line-of-sight deposition technique. The reported methodology introduces an inexpensive and straightforward approach for ASD that opens for exciting new possibilities for robust and less complex area selective metal-on-metal deposition.
Unavoidable Failure of Point Charge Descriptions of Electronic Density Changes for Out-of-Plane Distortions
Authors: Richter Wagner , Duarte Leonardo J. , Bruns Roy E.
Published: May 2021

Population analyses based on point charge approximations accurately estimating the equilibrium dipole moment will systematically fail when predicting infrared intensities of out-of-plane vibrations of planar molecules, whereas models based on both charges and dipoles will always succeed. It is not a matter of how the model is devised, but on its number of degrees of freedom. Population analyses based on point charges are very limited in terms of the amount of meaningful chemical information they provide, whereas models employing both atomic charges and atomic dipoles should be preferred for molecular distortions. A good model should be able to correctly describe not only static, equilibrium structures but also distorted geometries in order to correctly assess information from vibrating molecules. The limitations of point charge models also hold for distortions much larger than those encountered vibrationally.

Published: May 2021

A commercially available and EPA/PMRA registered quaternary ammonium antimicrobial formulation was applied to stainless steel carrier disks and sent to two virology research institutes to independently determine whether samples treated with SiQAC-C18 antimicrobial material could deactivate deposited SARS-CoV-2 virions on contaminated surfaces. The results independently support a sustained antiviral effect imparted from these treated surfaces by both SARS-CoV-2 virion destruction and degradation of viral RNA. These preliminary results indicate the SiQAC-18 treated surfaces could play an important role in mitigating the communicability and fomite transmission of SARS-CoV-2.

Published: May 2021

Herein, we report the catalytic use of multifunctional CuO nanoparticles (NPs) to oxidatively fractionate lignocellulosic feedstock with dioxygen in aqueous NaOH under mild conditions . In presence of CuO NPs, lignocellulose is fractionated into three parts, overall yielding 90% carbon efficiency. Lignin is converted to up to 45.6 wt% in organic soluble aromatic aldehyde monomers, rich in vanillin and syringaldehyde, the value surpassing the theoretical one based on b-O-4 bond content, indicating significant cleavage of other ether bonds. All hemicellulose is selectively converted into water soluble small (di)acids, mainly to oxalic acid. Up to 81% of cellulose, in contrast, is obtained as a white crystalline residue with high cellulose purity (over 95%), which can readily be transformed into high quality nanocellulose, useful in many applications.
Atomic Structure-free Representation of Active Motifs for Expedited Catalyst Discovery
Authors: Mok Dong Hyeon , Back Seoin
Published: May 2021

For CO* and H* binding energy prediction, we develop new representation of catalyst surface which split surface into three types of site, first nearest neighbor of adsorbates and second nearest neighbor in same layer and sublayer. From this representation and machine learning regression model, we achieve reasonable accuracy (0.120 eV for CO* and 0.105 eV for H*) with quick training (~200 sec using CPU). Because our representation does not require density functional calculation and atomic structure modelling, it can predict binding energies of possible active motifs without time-consuming steps.
Mapping Wave Packet Bifurcation at a Conical Intersection in CH3I by Attosecond XUV Transient Absorption Spectroscopy
Authors: Chang Kristina , Wang Han , Marggi Poullain Sonia , Prendergast David , Neumark Daniel , Leone Stephen
Published: May 2021

Extreme ultraviolet (XUV) transient absorption spectroscopy has emerged as a sensitive tool for mapping the real-time structural and electronic evolution of molecules. Here, attosecond XUV transient absorption is used to track dynamics in the A-band of methyl iodide (CH3I). Gaseous CH3I molecules are excited to the A-band by a UV pump (277 nm, ∼20 fs) and probed by attosecond XUV pulses targeting iodine I(4d) core-to-valence transitions. Owing to the excellent temporal resolution of the technique, passage through a conical intersection is mapped through spectral signatures of nonadiabatic wave packet bifurcation observed 15 ± 4 fs following UV photoexcitation. The observed XUV signatures and time dynamics are in agreement with previous simulations [H. Wang, et al. J. Chem. Phys. 151, 124106 (2019)]. Due to the short duration of the UV pump pulse, coherent vibrational motion in the CH3I ground state along the C-I stretch mode (538 ± 7 cm-1) launched by resonant impulsive stimulated Raman scattering and dynamics in multiphoton excited states of CH3I are also detected.

Published: May 2021

Three multichromophore thermally activated delayed fluorescence (TADF) molecules, p-di2CzPN, m-di2CzPN, and 1,3,5-tri2CzPN, were synthesized and characterized. These molecules were designed by connecting the TADF moiety 4,5-di(9H-carbazol-9-yl)phthalonitrile (2CzPN) to different positions of a central benzene ring scaffold. Three highly soluble emitters all exhibited near quantitative photoluminescence quantum yields (PL) in toluene. High PLs were also achieved in doped films, 59% and 70% for p-di2CzPN and m-di2CzPN in 10 wt% DPEPO doped films, respectively, and 54% for 1,3,5-tri2CzPN in 20 wt% doped CBP film. The rate constant of reverse intersystem crossing (kRISC) for p-di2CzPN and m-di2CzPN in DPEPO films reached 1.1 × 105 s−1 and 0.7 × 105 s−1, respectively, and kRISC for 1,3,5-tri2CzPN in CBP film reached 1.7 × 105 s−1. A solution-processed organic light-emitting diode based on 1,3,5-tri2CzPN exhibited a sky-blue emission with CIE coordinate of (0.22, 0.44), and achieved a maximum external quantum efficiency of 7.1%.

Published: May 2021

Application of deep learning techniques for the de novo generation of molecules, termed as inverse molecular design, has been gaining enormous traction in drug design. The representation of molecules in SMILES notation as a string of characters enables the usage of state of the art models in Natural Language Processing, such as the Transformers, for molecular design in general. Inspired by Generative Pre-Training (GPT) model that have been shown to be successful in generating meaningful text, we train a Transformer-Decoder on the next token prediction task using masked self-attention for the generation of druglike molecules in this study. We show that our model, LigGPT, outperforms other previously proposed modern machine learning frameworks for molecular generation in terms of generating valid, unique and novel molecules. Furthermore, we demonstrate that the model can be trained conditionally to optimize multiple properties of the generated molecules. We also show that the model can be used to generate molecules with desired scaffolds as well as desired molecular properties, by passing these structures as conditions, which has potential applications in lead optimization in addition to de novo molecular design. Using saliency maps, we highlight the interpretability of the generative process of the model.

Published: May 2021

Assaying enzymatic degradation of the water-insoluble substrate such as cellulose and synthetic polymers has remained technically challenging, primarily because only the surface of the substrate is accessible to the enzymes and the reaction proceeds very slowly compared with those of water-soluble substrates. Here we show an ultra-sensitive and semi-quantitative assay for enzymatic hydrolysis of cellulose. By combining nanofibrous matrices with piezo-driven inkjet printing and optical profilometry, enzymatic hydrolysis of less than 1 nanogram of crystalline cellulose was successfully quantified. Unprecedented genetic diversity of cellulase was revealed when the same principle was applied for elucidating microbial degradation of cellulose in the deep sea. This work demonstrates that truly interdisciplinary efforts, encompassing diverse disciplines from nanotechnology to microbiology, are crucial to address scientific and technological problems towards sustainability.

Published: May 2021

Bioprinting has evolved into a thriving technology for the fabrication of cell-laden scaffolds. Bioinks are the most critical component for bioprinting. Recently, microgels have been introduced as a very promising bioink enabling cell protection and the control of the cellular microenvironment. However, their microfluidic fabrication inherently seemed to be a limitation. Here we introduce a direct coupling of microfluidics and 3D-printing for the microfluidic production of cell-laden microgels with direct in-flow bioprinting into stable scaffolds. The methodology enables the continuous on-chip encapsulation of cells into monodisperse microdroplets with subsequent in-flow cross-linking to produce cell-laden microgels, which after exiting a microtubing are automatically jammed into thin continuous microgel filaments. The integration into a 3D printhead allows direct in-flow printing of the filaments into free-standing three-dimensional scaffolds. The method is demonstrated for different cross-linking methods and cell lines. With this advancement, microfluidics is no longer a bottleneck for biofabrication.

Published: May 2021

Following a synthetic chemistry blueprint for the valorization of lignocellulosic platform chemicals, this study showcases a so far unprecedented approach to implement non-natural enzyme modules in vivo. For the design of a novel functional whole cell tool, two purely abiotic transformations were incorporated into a recombinant bacterial host that allows production of complex lactone building blocks. This whole cell system streamlines the synthetic cascade, eliminates isolation and purification steps, and provides a high degree stereoselectivity that has so far been elusive in the chemical methodology.

Authors: Haraki Cristianne Aparecida Costa
Published: May 2021

Objetivo. Identificar a existência ou ausência de estratégias para a gestão de infodemia nos ministérios da saúde de 10 países da região da América do Sul (Brasil, Argentina, Uruguai, Paraguai, Bolívia, Peru, Chile, Colômbia, Equador, Venezuela).

Métodos. Definiu-se “estratégia” como o uso planejado de recursos para atingir ou concretizar determinados objetivos — sendo, neste caso, considerado como objetivo o combate à infodemia. Os sites eletrônicos oficiais dos ministérios da saúde dos países foram examinados de 28 de setembro a 10 de outubro de 2020 em busca de materiais, páginas eletrônicas ou aplicativos que sugerissem a existência de uma estratégia de combate à infodemia; informações sobre infodemia para cidadãos; e materiais comunicacionais como vídeos e cartazes. Ainda, utilizando “infodemia” como palavra-chave, foram buscados documentos oficiais (normativas, decretos, protocolos) que mencionassem medidas relacionadas à gestão da infodemia. Os resultados foram classificados em três categorias: existência de estratégia de gestão; existência de alguma ação de combate à infodemia; e ausência de informação sobre infodemia.

Resultados. Dos 10 países analisados, apenas a Argentina possuía uma estratégia destinada à gestão da infodemia. Brasil, Chile, Equador e Paraguai apenas faziam menção ao tema no site de seus respectivos ministérios da saúde; e nenhuma menção foi encontrada nos sites dos ministérios da saúde de Bolívia, Colômbia, Peru, Uruguai e Venezuela.

Conclusões. Os países estudados não fazem uso do conhecimento disponível acerca de estratégias de combate e gestão da infodemia.
Doing it for the ‘Gram: How Instagram affects values, and what it means for mental and ecological wellbeing
Authors: Vautier Melanie
Published: May 2021

What would it mean to cultivate a culture of thriving people on a thriving planet? Research has shown that intrinsic values are a significant predictor of both environmentally responsible behaviour and mental wellbeing. However, in modern Western culture, extrinsic, self-promotional values continue to grow in prominence. In order to examine how a specific social context may be exacerbating extrinsic values, counter to mental and ecological wellbeing, this study looks at the social media platform Instagram. Through in-depth interviews of young adults in Aotearoa New Zealand, this study examines their experiences of Instagram in order to ascertain if and how it may promote extrinsic values. Results were analysed through Self Determination Theory, which states that environments which thwart basic human needs of relatedness, competence and autonomy will incentivise extrinsic values. While in some cases, Instagram increased access to relatedness, participants also experienced thwarted relatedness when interactions became motivated predominantly by posting them, and thus self-promoting, on the platform. Participants also consistently reported feeling incompetent when comparing themselves to others' images, which, particularly when adjacent to advertising, as in the case of Instagram, is likely to lead to materialistic tendencies. Participants were also aware of, and in some cases responded to, Instagram signals as to what type of content would gain more 'likes,' adjusting their behaviour in order to succeed in a 'marketplace' infrastructure, thereby limiting autonomy. In doing so, intrinsically motivated experiences were overtaken by an extrinsic desire to portray them to others. These examples indicate Instagram’s infrastructural incentives toward extrinsic values, which counter societal goals of mental and ecological wellbeing. Pervasive messaging within social contexts such as Instagram needs to shift away from promoting extrinsic values in order to respond adequately to the current ecological challenges and create conditions conducive to mental wellbeing.
Life in Movement: A French Impressionist Critical Approach to Terrence Malick's Films
Authors: Johnson Matthew
Published: May 2021

Terrence Malick’s films from Badlands (1973) to The Tree of Life (2011) have generally received critical praise, as well as being the focus of detailed scholarly work. By contrast, his more recent films, what Robert Sinnerbrink refers to as the “Weightless trilogy” with To the Wonder (2012), Knight of Cups (2015) and Song to Song (2017), have been widely criticised and have been largely neglected academically. This thesis endeavours to situate the aesthetic features of these three films within a conceptual framework based in French Impressionist film theory and criticism. I will argue the ways in which these three films use natural light, gestures, close-ups, kinetic images and complex editing in relation to Germaine Dulac’s notions of pure cinema and Jean Epstein’s concept of photogénie. Moreover, these ideas can also be applied to films such as Days of Heaven (1978), The Thin Red Line (1998) and The Tree of Life. Thus, it is my contention that despite the significant changes to his filmmaking style evident in the Weightless trilogy, he remains a highly poetic director interested in the interior lives of his characters and the rhythms of life.

Reclamar y construir los paisajes comunales: Los devasos de Ciudad Rodrigo en la Edad Media
Authors: Martín Viso Iñaki , García Hernández Juan Ignacio
Published: May 2021

This paper focuses on the analysis of the ways which areas of collective use were created and claimed in the Middle Ages, through the case of the devasos of Ciudad Rodrigo. They were lands used preferentially to the grazing of cattle and to the collection of firewood; the inhabitants of the town of Ciudad Rodrigo as well as the neighbours of the villages that surrounded those areas had rights of entitlement to access. The means of claiming communal rights over those spaces between eleventh and fifteenth centuries have been studied thanks to a combination of archaeological record and written sources. The main hypothesis is the use of a claiming strategy based on sacralisation. First, burials linked the territory to the ancestors during early Middle Ages, and after the construction of buildings with religious functions, small churches that were not parishes, would have been a key to preserve the commons. Those politics of the sacred coexisted with the progressive identification of the devasos as properties of the council as a result of the affirmation of the power of the town of Ciudad Rodrigo.
Creative potential of a future music teacher: essense and content of phenomenon
Authors: Mariya Datsenko
Published: May 2021

The paper defines the essence and content of the phenomenon of creative potential of a future music teacher. Humanisation of domestic pedagogical science and practice has become dominant in the strategy of educational policy today. The main educational guiding principle is respect for the dignity of a person and development of their potential directed at the future. Creative potential, which is defined by many scholars as the presence of hidden, unused reserves in a particular type of human activity, becomes a sort of «a core» of a person. A natural self-organization of the creative potential of a future music teacher at all levels of hierarchy of organization ensures the convergence of this system to a certain optimum of negentropic stability due to environment and results in the formulation of the principle of systematic and dynamic complementarity, Le Chatelier’s principle and G. Hilmi’s law. Thus, based on achievements of modern science, it can be stated that the creative potential of an individual is a dynamic integrative personal quality (in the complex of personal abilities, knowledge, skills, beliefs, attitudes, orientation), which determines the need, readiness and ability of creative self-realization and self-development.
Digital learning of art theory
Authors: Lyudmyla Kondratska
Published: May 2021

The purpose of the paper is to substantiate of the pedagogical design of digital education of future art teachers, in particular, the study of art theory in a virtual art class. The essence of the author’s concept is manifested in the metadialogue (oscillation) of two approaches: cluster (focused on statistical visualization of neural a network of genre-style signs outside the spiritual context, i.e. on the “wealth of art”) and semasiological (focused on the anthropological interpretation of these genre-style signs as icons, indexes and symbols, i.e. “wealth of understanding of art”). The proposed project is based on the concept of research-oriented professional education (Inquiry Based Science Education) and technology of advanced learning (Technology Enhanced Learning), which provide bachelors with many opportunities to conduct art research as a performance. The organisation of the design environment of the virtual art class involves non-linear scaffolding in the process of remote virtual experiments on the portal Go-Lab (“Search Facility”, “Inquiry Spaces”, “Related Labs” or the link “Online Labs”); GRAASP environment for the implementation of author’s developments and pedagogically structured programs in the process of performative interaction between teacher and students. The systematic thinking and methodology of the proposed project — the methodology of performative action — implements the phenomenological-hermeneutic method of coherent modeling and expert evaluation of the theory of conceptual integration, connective theory of metaphorical interpretation,the concept of nonlinear epistemology, synthesis, principles of antinomy. The advantage of digital learning in creatively integrated art theory is that in the computer space the student feels unprecedented freedom of creativity and gets unique opportunities for performative action. Thus, the understanding of the causality of historical changes in the theory of art is the result of a performative act, in particular in the laboratory of errors. This requires the introduction of nonlinear logic of functional and meaningful expansion of artistic didactics, implementation of computational visualization technologies, network analysis, thematic intermedia modeling. The visualised results of the study demonstrated the successful integration of performative methodology of cognition as artistic creativity in the process of professional training of future art teachers.

The article presents the author’s understanding of the concept of “emotional intelligence of a music art teacher” as an integral, personal and professional quality of a future specialist. It contains determination of the content and structure of emotional intelligence of a music art teacher, the peculiarities of its manifestation due to the specifics of professional activity. The content of educational and methodical support for the formation of emotional intelligence of future bachelors and masters of music art in the process of professional training has been revealed. It includes normative and selective professional disciplines; various types of pedagogical practice (educational, psychological and pedagogical, summer pedagogical practice in health camps, teacher training practice in general secondary education institutions, assistant practice in higher education institutions); different types of research work; selective course "Theory and Methods of Emotional Intelligence Development". It is noted that the curricula of all normative and selective disciplines, different types of pedagogical practice as well as the topics of research work of students are enriched with emotional and intellectual component. The developed content of educational and methodological support is implemented in various organisational forms and methods of development of future teachers’ emotional intelligence, which were classified into three groups: general didactic, special, conditioned by the peculiar nature of music and specific, related to the phenomenon of emotional intelligence.
The structural components of the methodological competence of future leader of vocal ensemble
Authors: Valeriy Lymarenko
Published: May 2021

The article investigates the structural components of the methodological competence of the future leader of the vocal ensemble. The works of domestic and foreign scientists are analysed and the structural components of the methodological competence of the future leader of the vocal ensemble are developed. The essence of the concepts of “vocal ensemble”, “methodical competence” is revealed, the essence analysis and structure of the vocal ensemble has been carried out. The methodical competence of a modern specialist is a complex multi-component concept. Researchers come to the common opinion that methodological competence is an integrative set of knowledge, skills, and abilities that characterize the personality and mediate the specialist methodical experience, it is knowledge in the didactics field, teaching methods. Vocal training is a complex process, the training of the vocal ensemble future leader is impossible without it. The concept of “ensemble” is polysemantic. In musical performance it means any joint performance of a musical work. Therefore, such combinations as trio, quartet, quintet, and others are called ensembles. The vocal ensemble future leader must know the theoretical material and be acknowledged about the methods of working with the vocal ensemble.
The predictive power of approach and autonomous goal motivation for work engagement among public sector employees
Authors:   Oxford Brookes University, UK
Published: May 2021

This paper compares the relative predictive power of approach goal motivation and autonomous goal motivation for work engagement among public sector employees. To do so, it employs the goal-striving reasons framework within which people’s approach goal motivation is measured as well as the self-concordance theory which measures people’s autonomous goal motivation. Findings are based on cross-sectional and longitudinal data of 132 public service employees at time 1 and 78 employees at time 2. Overall, the results show, using multiple regression analysis, that approach goal motivation significantly predicts work engagement whereas autonomous goal motivation is not a significant predictor of work engagement. On an individual goal-reason level, a similar picture emerges. Pleasure and altruism, the two approaching goal-striving reasons, are descriptively more strongly correlated with work engagement than their comparable self-concordance reason of intrinsic and identified goal motivation. When testing the predictive power of pleasure and altruism with intrinsic and identified goal motivation simultaneously, using multiple regression analysis, pleasure remains the only significant predictor of work engagement at time one and time two. The findings suggest that approach motivation is a stronger predictor of work engagement than autonomous goal motivation for public sector employees. Additionally, the findings also indicate that pleasure is more important for the work engagement of public sector employees than their altruistic goal motivation on an individual goal-reason level.

Published: May 2021

The article considers the possibilities of using classical, progressive in the food environment container systems of grain harvesting in the seed production environment. The individual ability of such systems to combine technological operations without inter-operational transshipment of material is taken as a basis analytically, technologically, calculatively. As a feature the need to maintain its viability throughout the entire billet cycle without losses is taken into account analytically, technologically, calculatively. General issues analytically, technologically, and computationally take into account the negative impact of the presence of wheeled vehicles in the field with gross seed collections of up to 400 tons, the volume of a single feed of up to 4.2 m3 and marked personnel shortages by calculatively minimizing operators. It is analytically established, today there is no device that fully meets these requirements, in which either the requirement of combining technological operations was not met, or traumatic drying methods for breeding seeds were used, or there were structural difficulties in cleaning the body and low-intensity drying of grain. The result is a replacement drying and transport body for inclusion in the technology of the harvesting and transport process and post-harvest grain processing. The total operational economic effect: from the introduction of drying and transport removable bodies instead of the classic dump truck transport body, with a gross grain harvest of up to 400 tons, ranged from 4.7 thousand rubles/ha to 5.82 thousand rubles/ha - on average, this is 1.76 times lower, or 16% lower than the cost of using transport bodies installed on the “Multilift" system, but not having the ability to combine operations.

Farmer Exchange Rate (NTP) is a proxy indicator or an indicator of the approach to the welfare level of breeders. The welfare of breeders can illustrate the purchasing power of farmers. The purpose of this study 1) To determine the level of welfare of cattle breeders and 2) To determine the effect of price index factors paid by farmers on the price index received by cattle breeders.This study uses NTP time series data with the base year 2012 = 100 as the basis for calculating the years 2018 - 2019. The location studied was determined by purposive sampling method in 5 districts in Sidoarjo Regency which are centers of beef cattle and dairy cows. The sample was selected by purposive random sampling as many as 75 cattle breeders. The NTP analysis method was carried out descriptively and the analysis of the factors that influenced the NTP was carried out using multiple linear regression. The results showed that the exchange rate of cattle farmers in Sidoarjo regency in 2019 increased by 1.81 percent from 109.41 in 2018 to 111.21 in 2019. This shows that cattle breeders in Sidoarjo district are experiencing a surplus or prosperity. The production input price index which includes the price of seeds, feed, and labor wages that must be paid by cattle breeders is a factor that has a significant effect on the cattle price index received by breeders.

Bioinformatics has developed into an application tool for basic and applied research in the biomedical and biotechnology field. Polymerase Chain Reaction (PCR) is a common technique in the molecular area that has always involved bioinformatics science. PCR cloning techniques such as TA cloning and PCR-mediated cloning exhibit complex processes with low success rates. One easy, effective, and practical solution is to use a mega-primer with the Overlap Extension PCR Cloning (OEPC) technique. The success of PCR cloning using the mega-primer design in the OEPC technique is strongly influenced by the characteristics of the mega-primer used. Knowledge of mega-primer characteristics is one of the important factors in the success of PCR cloning. The design process for the mega-primer str promoter was characterized based on the principle of a genetic algorithm using the web-based bioinformatics tools such as ClustalW, NetPrimer, and BLAST. The success of the mega-primer construction in producing recombinant pSB1C3 vector has been confirmed by the sequencing method and the function of the reporting protein (AmilCP). DNA analysis shows a 100 % homologous sequence on the str promoter, whileÂ  E. coli colonies successfully express the purplish-blue color. Mega-primer characters can save costs and time of the research by maintaining the primer parameters that provide optimal values and increase the success value of PCR cloning via bioinformatics software. Hence, implications on biological problems, especially using DNA and amino acid sequences, could solve rapidly.

Saat ini, IT berperan sebagai enabler atau bahkan driver bagi bisnis organisasi untuk mencapai keunggulan bersaing organisasi tersebut. Hal ini menjadi tantangan bagi suatu perusahaan dalam mengelola kualitas layanannya yang berbasis IT (IT services). Bagaimanapun gangguan (incident) yang dialami oleh IT services kerap menimbulkan business impacts bagi suatu perusahaan penyedia IT services (IT services provider). Dengan demikian, incident perlu dikontrol dalam proses incident management yang mengacu pada best practices Information Technology Infrastructure Library (ITIL) untuk meminimalisir business impacts yang diakibatkan oleh incident. Beberapa perusahaan seperti PT. RST dan PT. XYZ belum sepenuhnya menerapkan incident management sehingga tidak semua incident yang terjadi pada IT services dari masing-masing perusahaan tersebut terpantau dan terkontrol dengan baik. Dengan demikian, studi ini bertujuan untuk menyusun Standard Operating Procedure (SOP) incident management pada PT. RST dan PT. XYZ berdasarkan ITIL 3 versi 2011. Data tentang kondisi eksisting perusahaan yang menjadi bahan penyusunan SOP ini, diperoleh dari wawancara secara daring dengan process owner di PT. RST dan PT. XYZ. Setelah SOP ini disusun, SOP ini diverifikasi dengan process owner masing-masing perusahaan tersebut. Dalam rangka continual improvement, SOP pada PT. RST dan PT. XYZ perlu dievaluasi kembali berdasarkan ITIL 4.
