A Critical Discourse Analysis of Selected Utterances of State Actors on the 2019 Xenophobic Attacks on Nigerians in South Africa
Authors: Fafiyebi Damilola Oluseyi
Published: October 2020

The study examined the discourse strategies employed by state actors in expressing their views on the 2019 xenophobic attack in South Africa. The objective is to examine how this group of people explores the provisions of critical discourse to shape and pattern their communicative intention. The data employed for the study were sourced from selected online media sources between September and November 2019. The study employed the Critical Discourse Analysis (CDA) approach with a particular focus on the Discourse Historical Approach framework proposed by Wodak (2001) as its theoretical springboard. The study established that different state actors from each of the countries under scrutiny engage in positive self and negative others presentation. This showed that from their discourses, it can be deduced that the state actors were all out to launder the image of their respective countries on the one hand and that of the kith and kin on the other hand.
Ideological Commitment in Modern African Poetry: Redefining Cultural Aesthetics in Selected Poems of Niyi Osundare’s The Eye of the Earth and Village Voice
Authors: Onyejizu Raphael Chukwuemeka , Obi Uchenna Frances
Published: October 2020

In this study, ideological commitment to cultural norms is a standpoint that has led to the development of modern African poetry. The Modern African poet is seen as an advocate for cultural prowess and transformation and as such naturally adopts this African traditional antecedent in his poems. Several critical studies on the two collections have focused on the stylistic and literary values of Osundare’s craft without appropriate reviews on the poet's use of cultural forms to reflect his ideological stance on pertinent issues affecting the society. The descriptive qualitative content analysis method was used to show how the selected poems reflect Homi Bhabha’s postcolonial theory of hybridity as expressed through the shifting of cultural margins in the society, thus, illustrating the use of cultural art forms as a means of appreciating nature and exploring issues of exploitation and marginalization. The study also examines the influence of the traditional Yoruba African culture on the poet with an adequate focus on the content and devices of orature, proverbs, riddles, parables, humor, satire, and traditional forms of language. The study submits that the poet adequately incorporated the ideals of culture and its elements in his enduring craft showing his allegiance to his folk cultural patterns.

This research is a response to the regional regulations high intensity violations phenomenon in governing the green open space in Denpasar City. The emergence of this phenomenon as a consequence of a regional regulation core, which is policy taken by the government as a result of synergy, compromise or even competition -in this research called as conflict- between ideas, theories, ideologies and interests. These various interests are the research’s main focus to aim the conflict of interest better understanding in open planning green space of Denpasar City, as part of public policy oriented to the relationship of the planning and development systems of the city. This research is designed using qualitative approach with interpretive method. Problems are examined through three elements of research, namely: (1) green open space in the context of spatial planning and formation; (2) interests involved in green open space planning; and (3) the influence of various interests on the existence of green open space. The findings of the study are that in the context of regional spatial planning, the emergence of violations phenomenon of regional regulations regarding green open spaces in the Denpasar City occurs because of three main conflicts, based on: (1) economic conflict; (2) political conflict; and (3) cultural conflicts. These three main conflicts then trigger the emergence of land use conflicts that threaten the existence of green open spaces in Denpasar City.

Published: October 2020

Nusa Nipa University is one of a number of universities in Maumere City, Sikka Regency, East Nusa Tenggara. Based on the Koppen climate classification, the City of Maumere is included in the savanna. The savanna climate is different from the tropical rain climate in terms of temperature, air humidity and wind speed. The high temperature in this city influences the perception of thermal comfort. Thermal comfort is a necessity for people performing activities in both outside and inside of building, one of those are students at Nusa Nipa University. This research was conducted by distributing questionnaire to 50 students occupying in 2 (two) different spots in the outdoor space. The result showed that 58% students felt comfortable in the grassy area with shade compared to other off-campus areas. This perception of comfort is influenced by comfort factors namely hardscape or softscape that exist in the outdoor space of the Nusa Nipa University.

Web-based Application for Classification Using Naïve Bayes and K-means Clustering (Case Study: Tic-tac-toe Game)
Authors: Indriyani Indriyani , Putera M. Ihsan Alfani
Published: October 2020

A database can consist of numerical and non-numerical attributes. However, several data processing algorithms, such as K-means clustering, can be used only in a dataset with numerical attributes. Data generalization by using Naïve Bayes and K-means clustering methods is usually employed WEKA (Waikato environment for knowledge analysis) application. Although the strength of WEKA lies in increasingly complete and sophisticated algorithms, the success of data mining still lies in the knowledge factor of the human implementer. The task of collecting high-quality data and knowledge of modeling and the use of appropriate algorithms is needed to guarantee the accuracy of the expected formulations. In this paper, we propose a simple web-based application that can be used like WEKA. The methodology used in this study includes several stages. The first stage is the preparation of data, which is the tic-tac-toe game dataset that is converted to CSV (comma-separated values) format. The next stage is the process of modifying data from non-numeric to numeric, specifically for clustering with the K-means algorithm. Afterward, the calculation of the distance between data is conducted and followed by data clustering. The final stage is the summary of these processes and results. From the experimental results, it was found that clustering can be done on categorical attributes that are transformed first into the numerical form using web-based applications.

Published: October 2020

Abstract. The development of a city cannot be separated from how its people view a city. People who understand how the culture of the city will give a strong identity and character to the city. Over time, there are differences in how people perceive elements of the city, one of which is the catuspatha. Catuspatha is no longer interpreted as empty space but began to get additional functions as aesthetic and elemental elements of city landmarks (landmarks). There are several meanings arising from the physical aspects and socio-cultural aspects of a catuspatha as a landmark of the City of Semarapura. This research focuses on Catuspatha Semarapura City in terms of physical and socio-cultural aspects. The data search was carried out by means of litelature studies, field observations and interviews with people who were active in and around Semarapura City. By using a qualitative descriptive method, this research results that the Semarapura catuspatha in terms of physical size has different criteria with its environment so that it is physically prominent, unique, easy to remember, easily recognizable, has historical and aesthetic value. From the socio-cultural aspects of the area around the Semarapura catuspatha also functions as a node, in which at this location a variety of activities are held mainly related to social and cultural activities such as Tawur Kesanga, Ngulapin, Nebusin, Ngelawang, and other activities including Ogoh-ogoh parade activities, various festivals and folk parties and also cultural marches.

Published: October 2020

In drilling operations it is intended to be able to conduct drilling quickly without causing damage to the drilling equipment and be able to produce good quality wells. Failure on the drilling pipe or bottom hole assembly (BHA) ranks results from loading that exceeds the maximum strength limit of the material. In this study, the calculation of the load on the downhole motor, where in the depth of the drill 512 meters failure occurs in the form of broken downhole motor. Based on the analysis conducted, at a depth of 494 meters the value of the hookload has increased quite high at 131.8 klb, while the maximum allowable hookload value is 121 klb, this indicates an overpull of 10.8 klb and based on the calculation of the drag value, a drag is obtained 38.8 klb while the maximum drag value is 28 klb, the difference between the actual drag value and the maximum allowable drag value is 10.8 klb, so it can be concluded that the failure that occurs in BHA # 10 is due to a drag that exceeds the maximum limit of 10.8 klb.
Las políticas territoriales de desarrollo rural de la Unión Europea: un balance de veinte años en Castilla y León
Authors: Gordo Gómez Pablo
Published: October 2020

La política específicamente agraria se ha mostrado insuficiente para dinamizar los espacios rurales de Castilla y León, cuyas características físicas y estructurales introducen limitaciones para la producción en el marco competitivo de la Unión Europea. Ante esta realidad, las políticas territoriales de desarrollo rural se presentan como la alternativa para aumentar la competitividad, apoyando la reconversión, diversificando las actividades económicas mediante el recurso al potencial endógeno y contribuyendo a fijar la población y mejorar la calidad de vida de los diferentes espacios rurales. El balance de la aplicación de las distintas actuaciones bajo el enfoque LEADER, durante las dos últimas décadas, ha sido: la promoción y desarrollo del turismo, con diversas opciones; y, el impulso de pequeñas y medianas empresas (PYMEs), que han contribuido a la transformación y comercialización de productos agrarios y a generar empleo. Sin embargo, este impacto se ha verificado en pocos núcleos de mayor tamaño, cuyo efecto difusor ha sido limitado para reducir los desequilibrios del espacio rural regional y no ha logrado participar activamente en redes europeas de cooperación transnacional.

Published: October 2020

La recolección de hongos silvestres comestibles se está convirtiendo en un importante motor generador de rentas en el medio rural. Este es el caso de lo que se podría denominar turismo micológico, un importante nicho de mercado dentro del subsector del turismo rural. A pesar de ello, no existen investigaciones de su importancia en las áreas rurales con recurso. Así, en la presente investigación se analiza su aportación a la economía de los territorios rurales de la Comunidad Autónoma de Castilla y León. Para ello se estiman cuatro variables fundamentales; el número de pernoctaciones y de viajes realizados por turistas micológicos, así como el gasto asociado y el empleo generado.
Difusión de prácticas de lucha contra la erosión en el olivar de la cuenca del Alto Genil Granadino
Authors: Calatrava Javier , Franco Juan Agustín
Published: October 2020

Este trabajo analiza el proceso de difusión de prácticas de lucha contra la erosión en el olivar de la provincia de Granada utilizando información de un sondeo a agricultores. Las prácticas más extendidas son el no laboreo y el uso de restos triturados de poda, mientras que otras más tradicionales son minoritarias. Pese a su efectividad contra la erosión y a su inclusión en las exigencias de varios programas agroambientales, el uso de cubiertas vegetales es muy reducido. El motor de los procesos de difusión de las principales prácticas analizadas ha sido la interacción y la comunicación directa entre los agricultores.
Internal Inconsistency and Risk Aversion: Implications on Smoking Decisions
Authors: Gil-Lacruz Ana I. , Gil-Lacruz Marta
Published: October 2020

The main contribution of this paper is an analysis of the nature of the link between internal coherence and risk aversion. Both variables play an important role in individual decisions concerning risk behaviors. We compare the levels of internal consistency and risk aversion among smokers and non-smokers. To measure the individual internal coherence and risk aversion; we use a survey that includes lottery questions. Our results confirm that smokers are consistent in their decisions and they behave as risk averse. These results should be treated with circumspection as lottery questions are based on monetary expectations that depend on socio-economic conditions and they obviate other dimensions such as social recognition.
Employees' Perceptions of the Effects of Retrenchment on Job Stress and Organisational Commitment in a Mining Company
Authors: Seteni Landiswa , Joubert Pierre , Dhurup Manilall
Published: October 2020

Over the past decade, South African organisations have had to cope with an ever-increasing rate of local and global changes. There have been considerable and ongoing socio-political changes, resulting from new government regulations. Most organisations have experienced some type of downturn, whether due to external business factors or poor internal performance. A typical response to organisational decline is retrenchment. Our study sought to explore employees’ perceptions of the effects of retrenchment on job stress and organisational commitment in a mining company. The study was located within a quantitative research paradigm. Four research hypotheses were posited and data was collected in one region from a sample of 400 surface mining employees, including management, administrators, engineers and artisans. The results showed that the effects of retrenchment did not have a negative impact on job stress (time stress and anxiety). This may be due to the fact that the mining company in question had a planning and consultation process in place for the employees prior to the retrenchment process. The results also showed that job stress (time stress and anxiety) was negatively associated with organisational commitment. To conclude this article we discuss the implications of our findings, outline the limitations of our study and make recommendations for future research.
Factors driving changes to remuneration policies in South Africa
Authors: Bussin Mark
Published: October 2020

This study was conducted in 2012 and replicates Bussin and Huysamenâ€™s (2004) work, conducted in 2003, on remuneration policies. It investigates the factors driving remuneration policy in South Africa and determines whether these factors have changed since 2003. Anonymous e-mail questionnaires were received from 131 senior company representatives. All participating companies were members of the South African Reward Association (SARA) or clients of a large remuneration consulting firm. Data were analysed using a chi-squared test and factor analysis. Results support Bussin and Huysamenâ€™s study, which found that the two main drivers of change in policy were the retention of talented staff and the financial results of the organisation. However, three components of remuneration are receiving greater prominence than they did in 2003: governance in the organisation, merit pay and retention strategies. These findings suggest a greater shareholder expectation that pay should be linked to performance, and that pay acts as a retention strategy for critical staff.
Domestic workersâ€™ lived realities of empowerment and disempowerment within the South African labour legislative context: Two sides of the same â€œcoinâ€
Authors: Marais Christel , Van Wyk Christo
Published: October 2020

South Africa is heralded as a global ambassador for the rights of domestic workers. Empowerment, however, remains an elusive concept within the sector. Fear-based disempowerment still characterises the employment relationship, resulting in an absence of an employee voice. The dire need to survive renders this sector silent. This article explores the role that legislative awareness can play in the everyday lives of domestic workers. By means of a post-positive, forwardlooking positive psychological and phenomenological research design the researchers sought to access the voiced experiences of domestic workers within their employment context. Consequently, purposive, respondent-driven selfsampling knowledgeable participants were recruited. In-depth interviewing generated the data. The distinct voice of each participant was noted during an open inductive approach to data analysis. Findings indicated that empowerment was an unknown construct for all participants. They lacked the confidence to engage their employers on employment issues. Nevertheless, domestic workers should embrace ownership and endeavour to empower themselves. This would sanction their right to assert their expectations of employment standards with confidence and use the judicial system to bring about compliant actions. The article concludes with the notion that legislative awareness could result in empowered actions though informed employee voices.
Job satisfaction, organisational commitment and work engagement in an insurance company
Authors: Sehunoe Norah , Viviers Rian , Mayer Claude-Helene
Published: October 2020

Retaining talented employees and keeping them healthy and well are increasingly important challenges for organisations in the age of the knowledge worker. Organisations are interrogating aspects such as the reasons why some employees are more satisfied, committed and engaged to their organisations than others. Another question is: what should managers do to ensure employee wellness within their organisations? This study explores the relationship between job satisfaction, organisational commitment and work engagement. Spectorâ€™s (1997) Job Satisfaction Survey, Allen and Meyerâ€™s (1990) Organisational Commitment Questionnaire and Schaufeli and Bakkerâ€™s (2004) Utrecht Work Engagement Scale were administered to a sample of 220 employees from a South African insurance company. The findings show mixed results with regard to significant correlations between job satisfaction, organisational commitment and work engagement. The majority of the findings suggest that there are significant correlations, of a large and medium effect, between scales, including a number of positive relationships of varying strength between job satisfaction, organisational commitment and selected components of work engagement. The findings could benefit organisations as they could contribute to a better understanding of what motivates their workers, particularly their levels of satisfaction, commitment and engagement, and what the combined effect of these might be on the retention and wellness of employees.
Fighting the battles of the mine workers: The emergence of the Association of Mineworkers and Construction Union (AMCU)
Authors: Mathekga Mmanoko Jerry
Published: October 2020

The Association of Mineworkers and Construction Union (AMCU) was formed in post-apartheid South Africa. AMCU organises workers in the mining and construction sector. The importance and relevance of AMCU in democratic South Africa should not be de-emphasised, given the high levels of labour exploitation by mining companies. The mining sector is regarded as a crucial engine for economic growth and social development. AMCU, as the mining and construction labour movement, plays an important role in ensuring that its members are well represented, work in decent working conditions and are not exploited but are protected instead from the capitalist system in which the global economy operates. However, in the post-apartheid era, trade unions have not been forceful enough in advancing the interests of their members; instead they have been accused of being too close to employers and of having been co-opted by the new government. They are faced with the challenges of outsourcing, labour brokers and contracting-out of services by employers. Trust in trade unions has also decreased. This paper examines the emergence of AMCU and its rise in the mining sector.
Women in mining: A conceptual framework for gender issues in the South African mining sector
Authors: Botha Doret , CronjÃ© Freek
Published: October 2020

New mining legislation aims to rectify previous inequalities and disadvantages in the mining sector and specifically provides for the inclusion of women in core mining activities. Although there is no lack of good will, the achievement of gender equality in the male-dominated mining sector remains one of the biggest equity challenges in the country and numerous problems accompany the deployment of women in core mining activities. The main objective of the study was to critically analyse gender issues in the mining sector and then to develop a conceptual framework that will enable the mining sector to contribute to and ensure the sustainable employment of women in this sector. A literature review was carried out to gain an in-depth understanding of the variables that have an impact on women in the mining sector specifically. An empirical study was conducted to identify and investigate relevant gender-related issues in the mining sector. Quantitative and qualitative research paradigms were used. The research revealed that various factors need to be considered for the successful and sustainable deployment of women in the mining sector. The study concludes by making recommendations and offering a conceptual framework that could be implemented and used by various stakeholders in the mining sector
The psychological contract in relation to employment equity legislation and intention to leave in an open distance higher education institution
Authors: Snyman Annette , Ferreira Nadia , Deas Alda
Published: October 2020

In recognition of the injustices of South Africaâ€™s apartheid past, employers have a responsibility to ensure that employment equity practices are implemented, without harming important aspects of the employment relationship, such as the psychological contract and the intention to leave. The aim of this study was to determine the relationship between the psychological contract, employment equity legislation practices and the intention to leave (as measured by structured questionnaires comprising standardised scales) in an open distance higher education institution. In this regard, special attention was given to the influence of employment equity on employeesâ€™ intention to leave, which forms an important part of the psychological contract. The study also focused on the differences that exist between the three different social groupings (Africans, white males and white females, coloureds and Indians), gender and qualification levels regarding their perceptions about how the psychological contract influences employment equity legislation practices and intention to leave. A quantitative survey was conducted on a stratified random sample of employees (N = 339) who were white (58.4%), male (50.1%) and between the ages of 31 and 60 and were all employed at an open distance higher education institution. Correlational statistics and multiple regression analyses revealed a number of significant relationships between the three variables. In the South African employment equity context, the findings provide valuable information that can be used to inform managers and human resource practitioners on employment equity strategies. The practical implications of the findings also add new insights in terms of the psychological contract, intention to leave and management of the employment relationship.
The relationship between personality and the capacity to think strategically
Authors: Crawford Vanessa , Hofmeyr Karl , Price Gavin
Published: October 2020

Effective leaders who have the capacity to solve complex, strategic business problems are a key differentiator in the new world of work. As external environmental changes converge with internal organisational shifts, the need for a strong bench of leaders becomes critical in driving profitable growth. This study explores the relationship between personality and the capacity to think strategically, an important component of managing the complexity of the emerging environment. Based on the California Psychological Inventory and Career Path Appreciation assessments of 256 managers and executives, the existence of relationships between a number of personality factors and the respondentsâ€™ future potential capability (FPC) were tested to identify which personality factors are predictors of the potential to think strategically. Anchored in Complexity Leadership Theory (CLT), this research builds on the leadership functions of CLT to provide new insight into the role of individual characteristics in the ability to think strategically. The consolidated findings identified Dominance, Flexibility, Achievement via Independence, Psychological Mindedness and Self-Acceptance as key constructs in the ability to think strategically. These outcomes sharpen the new leadership profile and enable the development of tools that can directly improve the organisationâ€™s ability to identify, attract, select and develop leaders who are proficient in the emergent, complex context.
Emerging actors in employment relations: Evidence of multipartism between the Nigerian Federal Government and the Academic Staff Union of Universities
Authors: Oludeyi Olukunle Saheed
Published: October 2020

The current trends in employment relations as they relate to decentralisation of production, outsourcing of workers to third parties, the emerging range of new employment arrangements such as agency work, contract or part-time work, casualisation and telecommuting are the result of globalisation along with intensifying emphasis on the adoption of international labour standards in workplaces. As a result Nigeria, like most countries of the developed world, has seen significant changes in its tripartite industrial relations. If we reflect on the number of actors who participated in the 2013 trade dispute between the Federal Government (FG) and the Academic Staff Union of Universities (ASUU), such changes depict industrial relations as multipartite rather than tripartite. While identifying these emerging multiple actors, this article places industrial relations in a broader multidisciplinary framework and demonstrates the need to review current theories, legislation, approaches and institutional frameworks while developing indigenous ones to achieve a proper and more in-depth understanding of the Nigerian model of multipartite industrial relations.
Changes in criteria air pollution levels in the US before, during, and after Covid-19 stay-at-home orders: evidence from regulatory monitors

Published: October 2020

The widespread and rapid social and economic changes from Covid-19 response might be expected to dramatically improve air quality. However, national monitoring data from the US Environmental Protection Agency for criteria pollutants (PM2.5, ozone, NO2, CO, PM10) provide inconsistent support for that expectation. Specifically, during stay-at-home orders, average PM2.5 levels were slightly higher (~10% of its multi-year interquartile range [IQR]) than expected; average ozone, NO2, CO, and PM10 levels were slightly lower (~30%, ~20%, ~27%, and ~1% of their IQR, respectively) than expected. The timing of peak anomaly, relative to the stay-at-home orders, varied by pollutant (ozone: 2 weeks before; NO2, CO: 3 weeks after; PM10: 2 weeks after); but, by 5-6 weeks after stay-at-home orders, the concentration anomalies appear to have ended. For PM2.5, ozone, CO, and PM10, no US state had lower-than-expected pollution levels for all weeks during stay-at-home-orders; for NO2, only Arizona had lower-than-expected levels for all weeks during stay-at-home orders. Our findings show that the enormous changes from the Covid response have not lowered PM2.5 levels across the US beyond their normal range of variability; for ozone, NO2, CO, and PM10 concentrations were lowered but the reduction was modest and transient.
Alkyl Halides as Both Hydride and Alkyl Sources in Catalytic Regioselective Reductive Olefin Hydroalkylation
Authors: Chen Xianxiao , Rao Weidong , Yang Tao , Koh Ming Joo
Published: October 2020

Among the plethora of catalytic methods developed for hydrocarbofunctionalization of olefins to date, reactions that regioselectively install a functionalized alkyl unit at the 2-position of a terminal unactivated C=C bond to afford branched products are scarce. Here, we show that a Ni-based catalyst in conjunction with a stoichiometric reducing agent promote Markovnikov-selective hydroalkylation of unactivated alkenes tethered to a recyclable 8-aminoquinaldine directing auxiliary. These mild reductive processes employ readily available primary and secondary haloalkanes as both the hydride and alkyl donor, obviating the need for additional hydrosilane, acidic or basic additives. Reactions of alkenyl amides with ≥five-carbon chain length regioselectively afforded β-alkylated products through remote hydroalkylation, underscoring the fidelity of the catalytic process and the directing group's capability in stabilizing five-membered nickelacycle intermediates. The operationally simple protocol exhibits exceptional functional group tolerance and is amenable to the synthesis of bioactive molecules as well as regioconvergent transformations.

Solar hydrogen evolution from water is a necessary step to overcome the challenges of rising energy demand and associated environmental concerns. Low-cost photocatalytic architectures based on polymeric light absorbers coupled to highly efficient molecular catalysts might represent an attractive platform to address this issue. However, to-date, our mechanistic knowledge of these systems is still largely underdeveloped. In this study, a molecular molybdenum sulfide hydrogen evolving catalyst, [Mo3S13]2–, is loaded onto polymeric carbon nitride (CNx) photoabsorber by impregnation. The resulting composite shows enhanced photocatalytic activity for hydrogen evolution compared to pristine CNx under monochromatic visible light (l = 420 nm) irradiation in the presence of sacrificial reducing agents. The light-driven dynamics of excitons and charges involved in hydrogen evolution catalysis were studied by a combination of spectroscopic (steady-state and time-resolved photoluminescence, femtosecond time-resolved transient absorption) and photoelectrochemical (open-circuit photopotential transients) methods. We demonstrate that the molecular molybdenum sulfide catalyst, at optimum loading (10 wt% nominal), improves the charge separation in the CNx absorber by facilitating the depopulation of emissive (band-edge) or non-emissive (shallow trap) states, followed by an effectively catalyzed transfer of electrons from the charge-separated state (deep trap) to protons in the solution. The results provide important insights into the complex interplay between polymeric light absorbers and molecular redox catalysts, indicating that the electron transfer to the catalyst occurs on relatively longer (nanosecond – seconds) time scale, as the catalyst had no impact on the ultrafast (sub-nanosecond) photoinduced kinetics in the CNx. These findings are of crucial importance for further development of soft-matter based architectures for solar fuels production.

Fluorescence imaging in the near-infrared II (NIR-II, 1000-1700 nm) region opens up new avenues for biological systems due to suppressed scattering and low autofluorescence at longer-wavelength photons. Nonetheless, the development of organic NIR-II fluorophores is still limited mainly due to the shortage of efficient molecular design strategy. Herein, we propose an approach of designing Janus NIR-II fluorophores by introducing electronic donors with distinct properties into one molecule. As a proof-of-concept, fluorescent dye 2TT-m,oC6B with both twisted and planar electronic donors displayed balanced absorption and emission which were absent in its parent compound. The key design strategy for Janus molecule is that it combines the merits of intense absorption from planar architecture and high fluorescence quantum yield from twisted motif. The resulting 2TT-m,oC6B nanoparticles exhibit a high molar absorptivity of 1.12 ⨯104 M-1 cm-1 at 808 nm and a NIR-II quantum yield of 3.7%, displaying a typical aggregation-induced emission (AIE) attribute. The highly bright and stable 2TT-m,oC6B nanoparticles assured NIR-II image-guided cancer surgery to resect submillimeter tumor nodules. The present study may inspire further development of molecular design philosophy for highly bright NIR-II fluorophores for biomedical applications.

Motivation: Poor protein solubility hinders the production of many therapeutic and industrially useful proteins. Experimental efforts to increase solubility are plagued by low success rates and often reduce biological activity. Computational prediction of protein expressibility and solubility in Escherichia coli using only sequence information could reduce the cost of experimental studies by enabling prioritisation of highly soluble proteins. Results: A new tool for sequence-based prediction of soluble protein expression in Escherichia coli, SoluProt, was created using the gradient boosting machine technique with the TargetTrack database as a training set. When evaluated against a balanced independent test set derived from the NESG database, SoluProt’s accuracy of 58.4% and AUC of 0.60 exceeded those of a suite of alternative solubility prediction tools. There is also evidence that it could significantly increase the success rate of experimental protein studies. SoluProt is freely available as a standalone program and a user-friendly webserver at https://loschmidt.chemi.muni.cz/soluprot/.

Published: October 2020

In line with Kiss et. al (2006), we have constructed an analytical framework for the timely detection of risks connected with the rapid growth of consumer lending, based on an econometric model for the equilibrium level of household and consumer loans. Results from an estimation on a panel of countries were extrapolated to the Ukrainian banking sector. The model suggests that after two waves of strong deleveraging starting in 2009 and in 2014, the consumer credit stock in 2019 is still well below its equilibrium level in Ukraine, despite the recent strong nominal dynamics.

Vector network analyzer usage at calibration of delay in satellite radio navigation system signal simulators
Authors: Krat N. M.
Published: October 2020

This article presents a method of vector network analyzer application at the task of global navigation system simulator calibration. Calibrated parameter is internal delay of the radiofrequency signal in simulator. Attention is payed to reducing of calibration uncertainty by means of taking into account the part, which is caused by impedance of simulator and other equipment mismatches. The goal of research is to estimate the non-excluded uncertainty after vector network analyzer measurements’ usage for correction calculation. Measured parameters are the group delay, reflection and transmission coefficients of cable with connectors, and reflection coefficients of simulator and oscilloscope. The goal has been achieved by means of simulation modelling. The main parts of modelling were simulation of vector network analyzer measurements’ and calculation the statistics of the non-excluded uncertainty. As the result, was shown, that if to use vector network analyzer for global navigation system simulator calibration, the part of uncertainty, caused by impedance mismatch, can be reduced in a several times.
