Synthesis, crystal structure, and magnetic properties of MgPr9Mo16O35 – structural comparison with the LiR9Mo16O35 (R = La, Ce, Pr, Nd)
Authors: Gougeon Patrick , Gall Philippe
Published: June 2023

Polycrystalline and single crystal specimens of the new quaternary phase MgPr9Mo16O35 were synthesized by direct solid-state reaction. MgPr9Mo16O35 presents a monoclinic unit cell (S.G. C2/m; a = 18.3422 (3) Å, b = 8.6188 (1) Å, c = 9.7276 (4) Å, = 101.9680 (4) and Z = 2). Its crystal structure was solved on a single-crystal by X-ray diffraction and refined to the final values R1 = 0.0281 and wR2 = 0.0473 (3903 independent reflections and 101 variables). For a comparative study the crystal structure of LiPr9Mo16O35 was also determined (a = 18.3422 (3) Å, b = 8.6188 (1) Å, c = 9.7276 (4) Å,= 101.9680 (4) and Z = 2; R1 = 0.0281 and wR2 = 0.0473). The crystal structure of both compounds is based on Mo16O26O10 units containing Mo16 clusters that share some of their O atoms to form infinite Mo-O cluster chains developing in the [010] direction and between which the Mg2+ or Li+ and Pr3+ cations are located. The increase of the charge transfer towards the Mo16 cluster due to the supplementary electron brought by the Mg2+ cations leads to some variations of the Mo-Mo distances. Application of the Mo-O bond-length–bond-strength relationship developed by Brown & Wu leads to a value of 55.1 electrons per Mo16 cluster in good agreement with that calculated from the stoichiometry (55 e-/Mo16). Magnetic susceptibility measurements confirm the presence of one unpaired electron on the Mo16 cluster.

Authors: Sotomayor Quispe Karen , Silva-Jaimes Marcial Ibo
Published: June 2023

In Peru, only 1 % of food processing companies located in Metropolitan Lima have obtained a technical validation for their HACCP plan. The low adherence to safety systems raises the goal of identifying the main barriers and difficulties for the implementation of the HACCP system. Data was collected by sending a questionnaire to 32 companies. In order to define the underlying structure of the barriers and difficulties identified we performed an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) based on a selection of nineteen (19) items, identifying four new factors that account for 66,7 % of the overall variability. After assessing their relevance, it was found that barriers and difficulties at the organizational/managerial level (F1) and in adaptation (F4), such as infrastructure and employee’s perception, were more relevant than attributes involving execution (F2), which comprises singular processes such as time, staff turnover, technology and others.
Decision-making process for gluing on footwear parts using AHP and statistics
Authors: Mares Castro Armando
Published: June 2023

In manufacturing processes, there are conditions that continually impact decision-making among when choosing among alternatives; the selection is usually influenced by critical aspects such as quality, productivity, costs and customer feedback, among others. This article analyzes different adhesives for the process of gluing parts for sports shoes in a company located in the city of Purisima del Rincon in Guanajuato, México. The analysis employs statistical engineering tools and an Analytic Hierarchy Process (AHP) methodology. The case studied deals with an issue with gluing parts. The glue currently employed is of good quality but has drawbacks such as its high cost and thickness, which leads to a time-consuming manual application, affecting productivity. We propose and apply an AHP model with input information obtained by means of industrial experimentation in order to select the best alternative. Objective and subjective judgments relate to the quality score, production capacity, ease of application, and utility per pair. The chosen alternative represented the best option after factoring in all aspects of interest for the overall goal.

Rationalizing the importance of business models for sustainability transitions: A conceptual exploration of incumbents and business model innovation
Authors:   Lund University, Johnson Emma
Published: June 2023

The current way of consumption and production is unsustainable in that society is exceeding the earth’s planetary boundaries and creating long-term and irreversible effects on an environmental, social, and economic level. There is a recognized need on all system levels to change the way that we operate. Industry is a key area that requires this attention, as it is largely responsible for the impacts from the production of various societal needs and functions. In particular, the building and construction industry accounts for about 37% of global CO2 emissions. Rapid decarbonization is needed, and technological innovation for electrification, as well as business model innovation towards circularity and sustainability is crucial. With the influence of business on production and the natural environment, it is important to understand how business models can contribute to sustainability transitions. Incumbents have often been perceived as creating barriers towards sustainable transitions, but they also have a large potential to transform industries due to their market power. Previous research has shown that innovative firms are essential for transitions, however, there are not enough insights on how significant business models are for transitions. This paper explores the connections of sustainable business model innovation research with sustainability transitions research and reflects on the ability of incumbents to innovate and contribute to sustainability transitions through insights from a construction equipment manufacturer.

Authors:   LUMSA University, Palagonia Chiara , Michelini Laura ,   LUMSA University, Mattelin-Pierrard Caroline ,   Panthéon-Sorbonne University
Published: June 2023

This article discusses the critical issues and barriers to implementing Industrial Symbiosis (IS), an economic strategy that incorporates the principles of Circular Economy (CE) at the cooperative-firm level. The authors conducted a Systematic Literature Review (SLR) to identify the main challenges faced by the plurality of actors in adopting the circular strategy, along with the barriers and limitations encountered in implementing IS. They identified seven issue areas: Action policy issue, Governance issue, Collaboration issue, Market issue, Economical issue, Logistic-technical issue, and Social-Environmental issue. The authors argue that digitalization and technological development are decisive allies in the effective implementation of CE practices, as they can improve collaborative relationships between companies and provide greater access to information on the costs and benefits of IS. The research is useful for practitioners who intend to implement CE strategies, such as IS, in the pursuit of sustainability and resource optimization.

Business Model innovation – Promoting spirituality and well-being in in a secular context: biographical insights from L’Abbaye de St Jacut-de-la-Mer
Authors:   Idrac Business School, Klapper Rita , Upham Paul ,   University of Groningen
Published: June 2023

This paper connects to conference track 3.2 relating to the human side of business model innovation. It focuses specifically on the role of values, roles and identity as elements of cognition, and the relationship of these to organisational structures and processes. Literature on the cognitive dimension of business models is longstanding but small, and mostly centres on the concept of cognitive models that provide descriptions and classifications of business model types, and that operate as recipes or templates for managers to follow. This study takes a more processual view, seeking to understand the origins of such cognitive templates. For this purpose, we adopt a phenomenological perspective and a biographical method: we take the case of one individual and trace the connections between their upbringing, experience and earlier life, including their values, roles and identities, and the model that they create and sustain for the business that they are responsible for. In this way, we seek to bring a dimension of lived experience to the concept of business models. As we are interested in furthering lower impact, more socially and environmentally sustainable business models, we take the case of a converted French Abbey that offers leisure accommodation and a degree of communal living that retains some of the structures of religious life. We highlight the way in which the Abbey’s manager managed multiple identities for herself, as she created a financially viable way for the Abbey to operate.
Barriers to social impact measurement in the intersection of circular and social enterprises: A single case study from Germany
Authors:   Technische Universität Berlin, Kolpinski, von Charleen , Bläute Alina , Cagarman Karina
Published: June 2023

This paper presents a specific form of a sustainable business model that applies a social circular economy approach while successfully doing business. Economic returns and ecological measures can be monitored accurately, but accounting for a company’s social impact is still challenging. Therefore, this paper presents a single case study about AfB: Europe's largest non-profit IT company that remanufactures IT devices and gives jobs to people with disabilities. The AfB creates a positive ecologic impact by saving natural resources, water, and CO2 emissions, and a positive social impact by creating jobs for people with disability, as around 45% of their employees have a mental or physical disability. Results from 15 interviews with managers and employees of the AfB plus secondary data show that the AfB undertakes many social activities but measuring the overall effects of these social activities needs improvement. So, this paper discusses barriers to social impact measurement in circular-social-hybrids in qualitative and quantitative data collection. Major barriers are the lack of capacity and resources for data collection and a lack of benchmarks, standards, and KPIs to calculate comparative numbers. In addition, social aspects are often intangible and sensitive, so it can be problematic to measure and report this sensitive information to the public. As a result, a framework is developed to assess the business models’ social and circular impact, which is of use for researchers and practitioners aiming to analyse a circular-social-hybrid.
Optimize Your Leadership Pipeline: Leveraging HR Analytics for Business Model Innovation
Authors:   Salem State University, Zhu Guorong , Wang Lan ,   Beijing University
Published: June 2023

Firms navigating the constantly changing business environment demand a supply of executives who can create and execute new business models, achieve financial targets, strengthen corporate ethical reputation, and transform the organization in pursuit of corporate sustainability. This paper aims to leverage human resources (HR) analytics to explore how high-potential managers navigate different developmental paths to reach the C-suite and how and why different developmental paths influence their turnover after becoming an executive. Combining job analysis and competency assessment with sequence analysis, we applied HR analytics on 53 general managers’ work experience spanning 57 years (n = 2,742), with roles, job requirements, and 20 executive competencies over 1,000 positions. Our findings reveal three distinct developmental paths that lead to the C-suite, characterized by differences in the content, context, timing, and complexity of work experience. Furthermore, we identify that a more complex developmental path tends to reinforce executives’ competency in self-awareness while inhibiting their development of technical competency, ultimately resulting in reduced executive turnover. Applying HR analytics with empirical data embedded in job and organizational contexts, this study reveals the importance of timing and complexity of work experience in executive development. It also offers insights for firms to leverage HR analytics to optimize their leadership pipeline and reduce executive turnover along with business model innovation.

INTELLIGENT MOVIE RECOMMENDER FRAMEWORK BASED ON CONTENT-BASED & COLLABORATIVE FILTERING ASSISTED WITH SENTIMENT ANALYSIS
Authors:   Department of Electronics & Comm. Engineering Amity University Uttar Pradesh, Lucknow Campus, Kumar Sachin
Published: June 2023

Recommendation systems for rating movies and forming opinion have grown exponentially in popularity, they make it very convenient for consumers to select films that suit their tastes. However, traditional recommendation systems often rely solely on user ratings or reviews, which may not accurately reflect the user's true feelings about a movie. To address this issue, sentiment analysis has been proposed as a more reliable method for capturing emotional information about movies. In this research paper, we propose a novel movie recommendation system that combines sentiment analysis with collaborative filtering and content-based methods. Our system is designed to provide accurate and timely recommendations to mobile users based on their preferences, reviews, and emotions. We evaluate the performance of our system using real-world data and demonstrate its effectiveness in improving the accuracy and timeliness of movie recommendations. In this research paper, we propose a comparative study of three popular movie recommendation techniques: content-based filtering, collaborative filtering, and sentiment analysis. We aim to evaluate the effectiveness of each approach in providing accurate and personalized movie recommendations. Work done has utilized MovieLens dataset for this study, which is a popular benchmark dataset for assessing movie recommendation systems. The dataset includes almost 100,000 ratings, ranging from 1 to 5, from 943 individuals on 1,682 films. Each rating has a timestamp, a special user ID, and a movie ID. The collection also contains details about each movie's genre. To prepare the dataset for our experiments, we first performed some data cleaning and pre-processing. We removed any duplicate ratings, and any movies or users with a low number of ratings were also removed. We also performed some feature engineering to extract relevant features from the raw data, such as movie genres, user demographics, and movie release dates. Our tests on the Movielens dataset show that the system we've suggested works well. Precision, recall, and F1-score were some of the measures we used to assess the system's performance. We discovered that it performed better than conventional recommendation systems that just use content-based or collaborative filtering techniques. A better user experience was produced with the use of sentiment analysis, which improved the accuracy and promptness of suggestions. Algorithm designed achieves a precision of 0.875, Recall of 0.0435, F1 Score of 0.0828, Accuracy of 0.9889, RMSE of 0.407, and F measure of 0.1813.

Authors:   Ph.D. Scholar,Department of Computer Science, Thapar Institute of Engineering & Technology, Patiala,Punjab,India, Kaur Jasmine
Published: June 2023

Pay-as-you-go access to computer resources is a major selling point of the cloud computing model. Cloud tenants demand complete networking of their dedicated resources to simply implement network functions and services, in addition to the conventional computer resources. The flexibility and convenience of on-demand resource provisioning make cloud computing a compelling computing platform. The key to meeting fluctuating needs and maximizing return on investment from Cloud-supporting infrastructure is dynamic resource allocation and reallocation. For traditional IaaS, we offer an energy-efficient resource allocation strategy based on bin packing. In this paper, we present an accurate energy-conscious method for initial resource allocation by casting the issue of energy-efficient resource allocation as a bin-packing model. The available VMs (virtual machines) employ a modified version of the max-min scheduling technique, which saves money and resources. The results of this study give a framework for comparing and contrasting the many different resource distribution approaches that have been proposed by other researchers. The importance of efficient data centers for the cloud is growing. Power consumption has been a major problem due to its expanding size and widespread usage. The overarching purpose of this effort is to create models and algorithms for resource allocation that are both energy-efficient and take into account a variety of relevant factors

Authors: Smrithi Sukesh , Doreen Hephzibah Miriam D. , C. R. Rene Robin
Published: June 2023

The number of data breaches in India has increased significantly in recent years. This is due to a number of factors, including the growing use of digital technologies, the lack of adequate data security measures, and the increasing sophistication of cybercriminals. The impact of data breaches can be far-reaching. Individuals may suffer financial losses, identity theft, and other forms of harm. Businesses may lose customers, suffer reputational damage, and incur significant costs to remediate the breach. The Indian government has taken some steps to address the problem of data breaches. However, more actions should be taken to strengthen data security measures and to educate businesses and individuals about the risks of data breaches. This research examines the rise of data breaches in India and uses the Air India case study to demonstrate the possible attacks in an airline company's infrastructure and how easily the customers' personal information can be stolen.
In Tension
Authors:   , Prisk Oliver
Published: June 2023

Between 1965 and 1975, my family owned a bach by the Opihi braided river, 25 minutes north of my hometown of Timaru. Old Super-8 camera recordings taken by my grandfather reveal the mnemonic characteristics embedded within the site: playing cricket in the field, swimming down at the river, playing at the river’s edge.

By 1975, the bach was demolished, subsumed by the dairy farm encompassing the site and the riverscape. This unique ecosystem of the river landscape, which is home to hundreds of native birds, insects and fish, has been compromised through farm runoff, and suffocated through the implementation of stopbanks that alter the physical course of the river. No remnants of the bach remain. Instead a pivot irrigator is positioned directly on the old footprint. The sense of personal loss that surrounds the site, and the degradation which has occurred through human intervention, has created a tension within the landscape.

This research explores these tensions between human and landscape through an architectural lens. It employs an iterative ‘design as research’ methodology to unravel the mnemonic and ephemeral qualities of the landscape, and asks how architecture may allow a view of this degradation, and the site itself, from a new perspective.

Prior to the design experiments, a literary context was developed that contextualizes the research within the discourse of key theorists who discuss architecture, art and the Anthropocene. Three case studies were then analyzed which depicted how creative practice relates to the surrounding landscape and the deeper underlying ephemeral conditions embedded within them.

Then, through a number of design techniques including photography, drawing, collaging and physical modeling, three design experiments took place: an installation, mid-scale proposal and a public-scale proposal, which sequentially developed in scale and architectural complexity.

These design experiments are carried out through a personal lens, embedding the personal mnemonic characteristics of the site within my architectural responses. It is directional, not prescriptive, in how architecture could intervene with these ecological issues, unraveling the complexities and tensions held within the site.

Suwerenność państwa ulegała i nadal będzie ulegać ewolucji. Wynika to ze zmian, które dokonują się w relacjach między państwami oraz wewnątrz samych państw. Na obecne rozumienie suwerenności mają wpływ rozmaite więzi, m.in. ekonomiczne, technologiczne, finansowe, a także militarne czy w zakresie bezpieczeństwa. Pojęcie suwerenności ulega dynamizacji, ale podlega też stałym zmianom w zakresie jej konceptualizacji. Wszystko to wymaga wszechstronnego zainteresowania doktryny i orzecznictwa sądów konstytucyjnych. Artykuł jest próbą zwrócenia uwagi na te zjawiska.
Sovereignty and Transnational Corporations
Authors: Bureš Pavel
Published: June 2023

The position and role of transnational corporations (TNCs) vis-a-vis the concept of sovereignty is specific. TNCs operate as an organism (an economic and social reality of a net created by a mother society, subsidiaries, and their suppliers anchored in different jurisdictions). The article presents three areas where the interaction of a state’s sovereignty and TNCs is the most visible. First, it discusses the issue of self-limitation with respect to administrative jurisdiction in cases related to foreign direct investment and the risk to the host state in situations where such autolimitation is not clearly framed. Second, the author presents the issue of human rights abuses committed by TNCs, the procedural challenges for redress, and the way-out created by soft law instruments adopted at an international level. Third, the concept of corporate citizenship is presented, which might undermine national sovereignty.
Sovereignty as a Factor in Securing, Securitizing, and Fragmenting Cyberspace
Authors: Jančárková Taťána
Published: June 2023

Information and communication technologies have played an important role in shaping the globalized world we live in today. While it is an accepted fact that globalization has challenged the understanding of the concept of sovereignty, the link between sovereignty and cyberspace is often not thought of at all. There are, however, multiple ways in which sovereignty has affected cyberspace as we know it. This article looks at how the notion of sovereignty contributes to the security, securitization, and, eventually, the possible fragmentation of cyberspace.
Application of the GC-MS method in combination with preliminary solid phase extraction on a magnetic molecular imprinted polymer for the determination of bisphenol A in soils of various types
Authors: Gubin A. S. , Kushnir A. A. , Sukhanov P. T.
Published: June 2023

A method of gas chromatography-mass spectrometry (GC-MS) in combination with pre-concentration on a sorbent with BPA molecular imprints (dosage of sorbent — 50 mg, sorption time — 10 min, pH — 3, desorption with methanol) is used to determine bisphenol A (BPA). The sorbent extracts about 96% of BPA from aqueous solutions with a single sorption and is characterized by a high imprinting factor reaching 7.1. The samples of soils of urbanized territories, as well as typical chernozems and residual carbonate chernozems outside the large cities of the Voronezh region were studied. The limit of BPA detection was 0.07 μg/kg (in terms of dry soil), the range of the linearity of the calibration graph was 0.3 – 35 μg/kg. Determination of bisphenol is hindered by soil contamination with petroleum products, which can be eliminated by washing with heptane. It has been revealed that pH of soils has a significant effect on the BPA migration of along the soil profile. The concentration curves of the BPA distribution over the soil profile up to a depth of 1 m were plotted. The maximum BPA concentrations in the soils of urbanized territories depend on the contamination of the territory with polymer waste. The maximum BPA concentrations (29.84 μg/kg) were determined at a depth of 20 cm in samples taken near the landfill of municipal solid waste. At other points within the city limits, the maximum concentrations range within 5.38 – 8.77 μg/kg. Outside the city of Voronezh, the mobility of BPA increases in more alkaline typical and residual-calcareous chernozems and significant concentrations of the pollutant were found at a depth of 50 – 80 cm. The developed scheme can be applied to targeted screening and monitoring of the BPA content. The method can be used for BPA determination in soil horizons for various soil types, meteorological conditions (precipitation, annual temperature regime), and contamination of the territory (the presence of unauthorized landfills, MSW landfills, sewage treatment facilities near the sampling point).
Study of the effect of shock wave loading on the structure and properties of bronze alloys BrAZh9-4 and BrAMts9-2
Authors: Kopytskiy V. O. , Petrov E. V.
Published: June 2023

Bronze alloys, due to their resistance to mechanical abrasion and high corrosion resistance, are used for the manufacture of machine parts and mechanisms that are subject to friction during operation. We present the results of studying the effect of shock-wave loading on the structure and properties of bronze alloys of grades BrAZh9-4 and BrAMts9-2. Shock-wave loading experiments were carried out by throwing the flyer plate onto cylindrical samples and compressing by a sliding detonation wave. The method of throwing a flyer plate accelerated by the energy of an explosion is often used to determine the spall strength of materials and the method of compression by a sliding detonation wave is used to create a large dynamic pressure inside the material. It is shown that at a throwing speed of a flyer plate of 2.4 km/sec, the impact pressure of the plate with the sample is 15 – 16 GPa, which exceeds the bronze shear strength. Under indicated loading conditions, the hardness of bronze increases by 53 and 25% for BrAZh9-4 and BrAMts9-2, respectively. Studies of the microstructure using scanning electron and optical microscopy revealed multiple cracks and micropores present on the surface of transverse sections forming a zone of spall fracture and areas turning into bands of localized deformation. Moreover, it is shown that when the samples are loaded with a flyer plate in a clip and without it, a greater number of cracks and shear areas are observed. Compression by a sliding detonation wave with a different amount of explosive charge revealed small defects present in the structure at the grain boundaries. The results obtained can be used to developed technologies for modifying and restoring the properties of bronze parts subject to shock-wave destruction.

Развитие коммуникативных навыков иноязычной подготовки студентов является сложным процессом. Так как язык многогранен, а в профессиональной лексике есть свои термины, которые понятны им самим.  Образование, особенно профессиональное, должно быть ориентировано не только на разностороннее развитие обучаемого и его личностные запросы, но и учитывать потребности общества.  Использование компетентностного подхода в образовании в значительной степени способствует достижению этих целей. Иностранный язык является одним из востребованных предметов в неязыковых вузах. Всестороннее комплексное развитие обучающихся вуза физической культуры в иноязычном образовании всегда представляло собой масштабную практико-ориентированную деятельность, требующую основательной теоретико-методологической подготовки и тщательного отбора соответствующих языковых средств и методов обучения. Достижение поставленных целей и решение намеченных задач возможно только в ходе активной, целенаправленной деятельности преподавательского состава, а также воспитательной работы в соответствии с систематическим графиком. Для иноязычной подготовки студентов спортсменов важным критерием является общение, коммуникация. При данном условии у студента выработается речь на иностранном языке. Умение общаться влияет на взаимодействие специалиста с другими людьми, на адекватную интерпретацию получаемой информации и ее правильной передаче. Студентам необходимо научиться высказывать и аргументировать свою точку зрения, слушать собеседника и приходить к компромиссному решению. Развитие профессионально-коммуникативных навыков иноязычной подготовки студентов-спортсменов, предполагает определенные методы, дидактический материал, профессиональную подготовку самого педагога, большой наглядный материал, а также использование новейших технологий.
