General role of amorphous aggregates in crystal nucleation
Authors: Liao Zhiyu , Das Ankita , Robb Christina Glen , Beveridge Rebecca , Wynne Klaas
Published: July 2023

There is mounting evidence that crystal nucleation from supersaturated solution involves the formation and reor-ganisation of pre-nucleation clusters contradicting classical nucleation theory. Here, a wide range of amino acids and peptides is investigated using light scattering, mass spectrometry, and in-situ terahertz Raman spectroscopy to demonstrate that the presence of amorphous aggregates with a wide range of sizes is a general phenomenon in supersaturated solutions. Additionally, these amorphous aggregates act as intermediates for laser-induced crystal nucleation. These observations are inconsistent not only with classical nucleation theory, but also non-classical theories involving liquid-liquid phase separation, requiring a new approach.
Multi-d-occupancy as an alternative definition for the double-d-shell effect
Authors: Moraes Matheus Morato Ferreira de , Aoto Yuri Alexandre
Published: July 2023

Despite of the prevalence of first-row transition metal containing compounds in virtually all areas of chemistry, the accurate modeling of these systems is a known challenge for the theoretical chemistry community. Such a challenge is shown in a myriad of facets, among them: difficulties in defining ground states multiplicities; disagreement in the results from methods considered highly accurate; and convergence problems in calculations for excited states. These problems cause a scarcity of reliable theoretical data for transition metal containing systems. In this work we explore the double d-shell effect, that plagues and makes difficult the application of multireference methods to this type of systems. We propose an alternative definition for this effect based on the mixing among d-occupancy configurations, or the multi-d-occupancy character of the wave function. Moreover, we present a protocol able to include this effect in multireference calculations using an active space smaller than the one usually used in the literature. A molybdenum-copper model system and its copper subsystem are used as example study cases, in particular, the molybdenum-copper charge transfer of the former and the electronic affinity of the latter. We have shown that our alternative definition can be used to analyze their reference wave functions qualitatively. Based on this qualitative description it is possible to optimize an active space without a second d-shell, able to obtain relative energies accurately. Seeing the double d-shell effect through the lens of a multi-d-occupancy character it is possible to correctly describe the wave function, improve the accuracy of the relative energies, and cheapen the multireference calculations. That way, we believe that this alternative definition has the potential to improve the modeling of first-row transition metal containing compounds both for their ground and excited electronic structure.

Published: July 2023

Herein we present previously unavailable C(sp3)-rich polycyclic hydrocarbon scaffolds which have a potential to become valuable tools in medicinal chemistry and crop science as saturated bioisosteres of benzenoids. We have developed a scalable protocol (up to 50 g from a single synthetic run) for the synthesis of tricyclo[3.3.0.03,7]octane (bisnoradamantane or stellane) 1,5-dicarbonic acid derivatives. X-ray crystallographic analysis of the stellane 1,5-dicarbonic acid dimethyl ester has revealed that this scaffold is an optimal saturated isostere for ortho-disubstituted benzene where substituents exhibit the in-plane topology. The synthetic protocol is based on the oxidative cyclization of dimethyl octahydropentalene-2,5-dicarboxylate (DMOD) through lithiation followed by I2 oxidation. The reaction outcome is determined by the stereochemistry of the substrate. While the endo,endo cis-DMOD, exclusively gives the "unwanted" Claisen cyclization product the exo,endo cis- and exo,exo cis- stereoisomers afford the desired stellane 1,5-dicarbonic acid dimethyl ester quantitatively. DFT computations have revealed that the reaction proceeds via the dianion of dimethyl octahydropentalene-2,5-dicarboxylate, which undergoes SET oxidation by I2 to form a radical anion. The subsequent cyclization followed by a second SET oxidation gives desired stellane derivative.
Shape-Assisted Self-Assembly of Hexa-Substituted Carpyridines into 1D Supramolecular Polymers

Published: July 2023

The role that molecular shape plays on the self-assembly of supramolecular polymers remains an open question in the field. We began addressing this fundamental question with the introduction of “carpyridines”, which are saddle-shaped monomers that can associate with one another through pi-pi interactions and in which the rotational and translational movements are restricted. The topography displayed by the monomers permits the assembly of highly ordered 2D materials even in the absence of strong directional interactions such as hydrogen bonding. Here, we introduce a simple strategy to gain control over the dimensionality of the formed structures yielding classical unidimensional polymers. These have been characterized using established protocols allowing us to determine and confirm the self-assembly mechanism of both fibers and 2D sheets. Fascinatingly, the calculated interaction energies are significantly higher than expected for a self-assembling system lacking “strong” non-covalent interactions. The versatility of this supramolecular unit to assemble into either supramolecular fibers or 2D sheets with strong association energies highlights remarkably well the potential and importance of molecular shape for the design of supramolecular materials and the applications thereof.

Published: July 2023

Magnetism in atomically thin two-dimensional (2D) materials is attractive for several applications such as memory devices, sensors, biomedical devices, etc. Here, we have synthesized 2D manganese telluride (MnTe) using a scalable synthesis method consisting of melting followed by liquid phase exfoliation (LPE). Both bulk and 2D MnTe samples were analyzed for their magnetic behavior at room temperature and lower temperatures (10 K). A change from antiferromagnetic to paramagnetic behavior was observed in 2D MnTe flakes. Enhanced magnetic saturation values (up to 400% increase) were observed as compared to bulk MnTe in RT. Density functional theory (DFT) simulations explain the layer-dependent magnetic behavior of the 2D MnTe flakes, as well as the antiferromagnetic to paramagnetic transition due to an unbalanced spin population.

Published: July 2023

Alzheimer’s disease (AD) is the most common form of dementia that affects millions of people worldwide. The hallmark of this disease is the accumulation of amyloid-beta (Abeta) aggregates that lead to neuronal death and cognitive defects. Various chemical reagents, including transition metal complexes, have been developed to change Abeta peptides with the consequent impact on their aggregation profiles; however, the examples of Abeta modifications by transition metal complexes are very limited. Here we report, for the first time, the site-specific modifications of Abeta peptides using a mononuclear cobalt complex, [CoII(TBDAP)(H2O)(NO3)](NO3) (Co(II)(TBDAP); TBDAP = N,N-di-tert-butyl-2,11-diaza[3.3](2,6)-pyridinophane). Co(II)(TBDAP) can induce modifications onto Abeta peptides, including decarboxylation and deamination, fragmentation, and a combination of both. Our spectrometric and spectroscopic studies manifest that the oxidation of the Co(II) center to Co(III) by O2 is a crucial step for inducing these modifications, which is further supported based on the reactivities of a newly synthesized Co(III) complex, [CoIII(TBDAP)(Cl)2](NO3) (Co(III)(TBDAP)), towards Abeta peptides. Such modifications onto Abeta by Co(II)(TBDAP) can redirect its on-pathway aggregation to off-pathway, yielding relatively less toxic short fibrils or amorphous aggregates. Our work provides valuable insights into the distinct reactivities of cobalt complexes towards Abeta peptides, which offers a novel strategy to control Abeta amyloidogenesis using transition metal complexes.

Lighting the way: The vital role of community initiatives in co-evolutionary processes of postcapitalist transformation
Authors:   , Mattera Katheryn
Published: July 2023

It has become evident that transformative change is required to address today’s multiple global crises in a durable and just way. This thesis argues that community initiatives are crucial loci for transformation: spaces in which new ways of being, doing, and knowing are embodied, practiced, made habitual, and disseminated. From a degrowth perspective and guided by a Gramscian model of co-evolutionary change, a series of semi-structured interviews were undertaken to explore how community initiatives in Wellington and Nelson, New Zealand foster transformation across a range of scales, and how they shape, and are shaped by, government. This thesis develops and applies a postcapitalist analytical map to take stock of the key values and practices that characterise processes of transformation, illuminating the vital role that community initiatives play in fostering these values and practices. Resourcing, relationships, and communication are found to be key enablers and challenges for these initiatives, and the transformative potential of community initiatives co-evolving with government is explored, building the case that individual practices are interwoven with shifts aa larger scales. These findings contribute to a large body of research theorising sustainability transformations beyond growth, and this thesis attends to a number of gaps in that literature: it answers a call for those exploring sustainability transitions to engage with theories of social change, conceptualises a degrowth transformation strategy, and embarks on a shared quest to answer the all-important – but neglected – question of how to move toward a postcapitalist society. This thesis has also sought to celebrate and bolster the efforts of community initiatives by highlighting the importance of their work and by amplifying and grounding in research their calls for policy action, for government regulation, and for a more autonomous and valued community sector.

Gender Equality in Science Classrooms: Examining the Implementation of Gender-responsive Approach and its Impact on Science Education
Authors: Canuto Peter Paul , Espique Felina
Published: July 2023

Gender-responsive education promotes gender equality at schools and can be attained by addressing students’ gender issues through gender responsiveness. In view of gender equality, the study examined the experiences of two Science teachers in implementing a gender-responsive approach to instruction and its impact on students' learning in secondary Science classrooms. Data were gathered through purposive sampling and descriptive phenomenology, supplemented by follow-up interviews, and then analyzed using Colaizzi's phenomenological approach. The interviews were conducted through online video calls with a semi-structured questionnaire. With thorough analysis, five major themes emerged from the teachers' shared experiences. These themes pertain to the students' genders and performances, gender-responsive approaches and methodologies, and the effects and challenges of implementing a gender-responsive approach in Science education. Furthermore, the teachers' gender responsiveness was reflected in preparing lessons, instructional materials, gender-fair language, extracurricular activities, a profiling system, sharing, group work and projects, reporting and presentation, problem-solving and laboratory activities, games, and assessments. Consequently, the teachers affirmed that gender equality among Science classroom students was achieved. With the surge of concerns surrounding students' gender, a gender-responsive approach must be upheld. Though the study's results directly relate to Science education, it is hoped that it will contribute to the pedagogical knowledge of teachers in other disciplines in integrating gender and addressing gender issues in the classroom.

Published: July 2023

Infections with OXA-244-carbapenemase-producing Escherichia coli with sequence type (ST)38 have recently increased in Europe. Due to its low-level activity against carbapenems, OXA-244 can be difficult to detect. Previous assessments have not revealed a clear source and route of transmission for OXA-244-producing E. coli, but there are indications of non-healthcare related sources and community spread. Here we report a hospital-associated outbreak of OXA-244-producing E. coli ST38 involving three hospitals in Western Norway in 2020. The outbreak occurred over a 5-month period and included 12 cases identified through clinical (n = 6) and screening (n = 6) samples. The transmission chain was unclear; cases were identified in several wards and there was no clear overlap of patient stay. However, all patients had been admitted to the same tertiary hospital in the region, where screening revealed an outbreak in one ward (one clinical case and five screening cases). Outbreak control measures were instigated including contact tracing, isolation, and screening; no further cases were identified in 2021. This outbreak adds another dimension to the spread of OXA-244-producing E. coli ST38, illustrating this clone’s ability to establish itself in the healthcare setting. Awareness of challenges concerning OXA-244-producing E. coli diagnostic is important to prevent further spread.

Published: July 2023

Introduction

National and regional carbapenemase-producing Enterobacterales (CPE) surveillance is essential to understand the burden of antimicrobial resistance, elucidate outbreaks, and develop infection-control or antimicrobial-treatment recommendations.

Aim

This study aimed to describe CPE and their epidemiology in Norway from 2015 to 2021.

Methods

A nationwide, population-based observational study of all verified clinical and carriage CPE isolates submitted to the national reference laboratory was conducted. Isolates were characterised by antimicrobial susceptibility testing, whole genome sequencing (WGS) and basic metadata. Annual CPE incidences were also estimated.

Results

A total of 389 CPE isolates were identified from 332 patients of 63 years median age (range: 0–98). These corresponded to 341 cases, 184 (54%) being male. Between 2015 and 2021, the annual incidence of CPE cases increased from 0.6 to 1.1 per 100,000 person-years. For CPE-isolates with available data on colonisation/infection, 58% (226/389) were associated with colonisation and 38% (149/389) with clinical infections. WGS revealed a predominance of OXA-48-like (51%; 198/389) and NDM (34%; 134/389) carbapenemases in a diversified population of Escherichia coli and Klebsiella pneumoniae, including high-risk clones also detected globally. Most CPE isolates were travel-related (63%; 245/389). Although local outbreaks and healthcare-associated transmission occurred, no interregional spread was detected. Nevertheless, 18% (70/389) of isolates not directly related to import points towards potentially unidentified transmission routes. A decline in travel-associated cases was observed during the COVID-19 pandemic.

Conclusions

The close-to-doubling of CPE case incidence between 2015 and 2021 was associated with foreign travel and genomic diversity. To limit further transmission and outbreaks, continued screening and monitoring is essential.
Early warning systems against bankruptcy risk and NLP: can ChatGPT predict corporate distress?
Authors:   University of Gdańsk, Faculty of Management, Department of Strategic Development, Siciński Jędrzej ,   Sopot
Published: July 2023

Purpose: The main purpose of this paper is to evaluate the effectiveness and usability of one of the more groundbreaking and more widely commented NLP-technique-employing inventions, i.e., the ChatGPT application acting as a digital advisor in the field of counterparty financial standing and bankruptcy risk assessment. Design/methodology/approach: The algorithmic potential presented by the ChatGPT tool can be a valuable solution in supporting the manager's work. In this study, the current potential of this solution in supporting financial analysis, and in particular, bankruptcy risk assessment, was checked. The study was carried out using the following methods: analysis and synthesis (1.), critical analysis of the literature (2.), and an experiment involving the use of a natural language processing application (3.). Findings: In the course of the research, it was found that the ChatGPT tool, according to the current state of knowledge, has extensive usability and is able to conduct interactions that in many cases are similar to communication with a human being. The tested language model shows a much higher level of training on general data than in solving narrow problems in specific fields. Nevertheless, its development potential should be assessed highly and probably its adaptation to solve highly specialized tasks in management will not be a long-term process, which makes it a candidate for the role of a digital managerial advisor in the future. Research limitations/implications: The first stage of the research covered only solving problems with the use of the simplest algorithms, such as discriminant analysis (MDA) and the study of entities whose financial statements are widely available on the web, which was a relatively low level of complexity for the language model. Practical implications: The research results are a signal that digitization and the digital revolution are not just theoretical slogans, but real functioning technologies that can change the nature of the manager's work (and the entire management system) in the near future. The development potential of NLP technology in management, which was confirmed in this work, suggests that an appropriate strategy for implementing these technologies is needed today. Originality/value: In this study, one of the first attempts was made to assess the potential and adaptability of natural language processing systems to support a manager in assessing the financial condition and risk of bankruptcy of entities. Keywords: early warning systems against bankruptcy, insolvency, artificial intelligence, natural language processing, chatGPT. Category of the paper: Research paper, Literature review.
Green public procurement from the contractor’s perspective
Authors:   Faculty of Organization and Management, Silesian University of Technology, Szewc Tomasz , Szymańska Karina ,   Faculty of Organization and Management, Silesian University of Technology
Published: July 2023

Purpose: Governments in many countries are trying to prevent climate change. One way of doing this is through green public procurement that consists of procuring goods, services and works with a reduced environmental impact during their life cycle compared to goods, services and works with an identical purpose that might otherwise have been procured. So the paper aims to examine private companies’ readiness to provide green goods and services in response to demands of green public procurement. This may encourage public entities to wider use of green public procurement because they may be afraid of an inadequate amount of companies that can meet the procurement criteria. The paper provides tips on how to organize the work of a public institution to make green public procurement more widespread. Design/methodology/approach: The methods used in this study were literature analysis, statistical survey, static analysis and case study. By means of a statistical survey and analysis, the relationship between the knowledge of employees of a given company regarding the knowledge of concepts related to green public procurement and the type of position was demonstrated. On the other hand, with the help of a case study, it was shown how an existing public procurement can easily be transformed into a green public procurement. Findings: In order to achieve sustainable outcomes, it is necessary to introduce internal regulations of public organisations relating to the integration of environmental considerations into tendering procedures. Public organisations should realise how easy it is to turn a public procurement into a green public procurement and that companies are already ready to do it. Almost any company can meet the environmental requirements to participate in green public procurement, the criteria depend on the ingenuity of the public organisations' staff. The main difficulties in including environmental aspects in tendering procedures include insufficient knowledge and experience of the contracting authorities in their practical application. Originality/value: The paper discusses the role of green public procurement, as well as how to manage a public organisation, what to do to make green public procurement widely used. Relevant knowledge of public employees, political will, as well as the fashion for green public procurement are important in the introduction of the above mentioned procurement. The paper also focuses on the private company's point of view. Keywords: carbon footprint, public procurement, green public procurement, climate change. Category of the paper: research paper.
Implementation of EU law into the Polish consumer protection law, with particular emphasis on the Omnibus Directive
Authors:   Opole University of Technology, Szymura Monika
Published: July 2023

Purpose: On 1 January 2023, provisions implementing the Omnibus Directive, along with the Digital Content and Safe of Goods Directives, came into force in Poland. The aim of the implementation is to adjust consumer protection in response to advancing digitisation and new business models. This article focuses on the changes introduced to consumer protection laws as a result of the amendment of 1 December 2022 implementing the Omnibus Directive into the Polish law. Design/methodology/approach: The deliberations are based on the related subject literature and an analysis of the legal provisions applicable in the area under discussion. Findings: With the implementation into the Polish legal order of the Directive 2019/2161, legislators introduced numerous changes in consumer law, including new obligations for the providers of online trading platforms, and rules for the provision of information about price reductions of goods and services. The main implication of the implementation of the Omnibus Directive is the change from physical and legal defects to compliance (or non-compliance) of the goods with the contracts, and the extension of the limitation period for consumer claims. Adjusting their business to the new legal requirements, entrepreneurs will need to implement far-reaching organisational changes, which paradoxically, from the consumer’s point of view, could lower the traditionally perceived level of protection. With respect to the legal aspects of some of the implemented provisions selected in this article, it should be concluded that the transposition of most of the solutions of the Omnibus Directive was carried out correctly, although certain inconsistencies could not be avoided. Practical implications: Adjusting their business to the new legal requirements, entrepreneurs will need to implement far-reaching organisational changes. For these reasons, the importance of knowledge about the consumer protection, has been increasing in value. Originality/value: The article raises the issue of consumer law, which is important not only from the point of view of the customer but also from the entrepreneur’s perspective. Keywords: consumer law, implementation, digital market, entrepreneurs’ obligations. Category of the paper: viewpoint, literature review.

Bu nedenle tasarım aşamasında öngörülen yapı davranışı gerçeği yansıtmamakta ve deprem tehlikesinin yüksek olduğu Ülkemizde dolgu duvarlar yıkıcı etkilere neden olabilmektedir. Bu çalışmada betonarme binalarda dolgu duvar etkilerinin incelenmesi için farklı özelliklere sahip 6 adet bina modeli tasarlanmıştır. Dolgu duvar etkileri ile meydana gelebilecek olası yumuşak kat düzensizliğini ortaya koyabilmek için iki faklı zemin kat yüksekliği dikkate alınmıştır. Çalışma kapsamında boş çerçeve, çizgisel yüklü çerçeve ve çizgisel yük + eşdeğer basınç çubuklu çerçeve olmak üzere üç farklı betonarme bina modeli tasarlanmıştır. Betonarme bina modellerinin doğrusal ve zaman tanım alanında doğrusal olamayan analizleri gerçekleştirilmiştir. Çizgisel yük + eşdeğer basınç çubuklu sitemlerin boş ve çizgisel yüklü sistemlerle kıyaslanması durumunda periyot değerlerinde, tepe noktası yerdeğiştirmelerinde ve etkin göreli kat ötelenme değerlerinde azalma, spektral ivme değerlerinde ve taban kesme kuvvetlerinde artma ve yumuşak kat düzensizliği oluşumu belirlenmiştir. Dolayısıyla, betonarme bina modellerinde dolgu duvarların eşdeğer basınç çubuklu olarak modellenmesinin yapı davranışı açısından daha doğru sonuçlar vereceği kanaatine varılmıştır.

Todays, the increasing success rates, and intensity of use of implant applications have attracted attention in the field of dentistry to dental implants. In this study, the temperature and stress distribution in a dental implant was modeled in three dimensions using the commercial software Ansys, which uses the finite element method. The changes in the implant prosthesis were investigated by applying a 100N load to the model and a temperature of 45o C and 10o C, respectively. The temperature input condition was accepted as the temperature of freshly taken food/beverage from the stove for the highest temperature and the temperature of freshly taken out of the refrigerator for the lowest temperature. As a result of the analyzes (Fluid Flow), it was observed that the implant prosthesis didn’t conduct heat to the tooth root at 45o C and 10o C. As a result of the von Mises stress distribution and total deformation analysis under a load of 100 N, it was determined that the tensile and compressive strength was good (48.17 MPa), and most of the applied load was supported by the artificial tooth crown. The chewing force applied due to its structure from the tooth geometry causes non-homogeneous stress distribution in all axes. Thus, it reveals that mechanical compatibility is of great importance as well as biocompatibility. Titanium alloys (Ti-6Al-4V), which are frequently used in tooth crowns and tooth roots, cause differentiation in bone structure together with the formation of a protective oxide layer. Considering the loss of bone volume and resorption diseases, especially during the osteoporosis/menopause, it is possible that a problem may occur at the implant-bone interface.

Based on the accident data’s, which recorded that 2016 until 2019, there were everage 225 traffic accidents involving students and college student riders. From these accident data’s, was found that the male rider dominated traffic accidents than female rider. This study aims to determine how a simple model can be done based on difference a demographic aspect such as differences of gender influences, differences of economic and social aspect on the driving behavior of student and college students on traffic accidents in Mataram City. The Structural Equation Modeling (SEM) method, with the help of the AMOS program was used in this study. The number of respondents in this study were 792 people, consisting of 391 students and 391 college students. The model in this study consisted of 3 variables, namely behavior, violations and accidents. Driving behavior has a significant effect on traffic violations with a probability value (P) = 0.000 (<0.001), and a testing value of C.R> 1.64. The size of the estimated value in the student group shows that the effect of behavior on violations in male student rider is 30.08% stronger than that of female rider. And the effect of behavior on violations among female students is 0.8% stronger than college students. Traffic violations have a significant effect on traffic accidents with a probability value of 0.000 (<0.01), and a test value of C.R> 1.96. Traffic violations on male students have an effect on accidents by 0.992, 50.1% stronger than female students. The effect of traffic violations on student rider on accidents is 2.44% stronger than female student rider. Gender differences have a significant effect on driving behavior based on the probability value (P) = 0.000 (<0.001). On the otherhand, the results of the analysis show that the driving behavior model of the community on the Mataram City based on the review of the economic and social aspects shows a model with a variety of patterns where the GRDP review follows the Polynomial model, based on the number of cityzen population, the tendency of the Exponential model and the review of the gender probability aspect follows the Logarithmic model pattern
