Authors: Kobzev Egor , Kapustina Nadezhda
Published: November 2023

The purpose of the work is to analyze the directions for improving methods for reducing risks and their damage during conflicts in organizations. The author of the work studied the main provisions that relate to approaches to the study of risks in organizations in the context of the emergence and development of conflicts. Next, key areas for improving approaches and methods were identified using the example of an economic entity. As the first proposal aimed at creating a risk management system in the organization, the introduction of a modified Japanese ringisei system into the Adventus company was singled out. The modification is connected with the introduction of the horizontal movement of proposals into the existing model. Further, the direction related to the improvement of regulatory regulation by adding and developing several elements, such as the company's code of ethics, the corporate code of enterprises, the company's charter, was noted. The author noted the importance of promoting and developing corporate culture in the company, taking into account the specifics of the activities of Adventus LLC, organizing round tables and similar events to improve the quality of communication between employees. The work considered the direction associated with the introduction of a system of balances between long-term and short-term activities. The final direction, which was noted by the author, was the introduction of a «web» of interaction and diversification of work responsibilities. Further, the work assessed the effectiveness of the proposed measures based on the formula «risks from conflicts in the enterprise». The author identified key indicators that were considered on the example of Adventus LLC and which can be applied to the analysis of other organizations. In conclusion, the author formed conclusions regarding the further improvement of methods to reduce the risks associated with conflicts in the organization.

Authors: Ndelu Hazel Lizzy , Utete Reward
Published: November 2023

Practising organisational culture is indispensable in boosting sustainable development of various organisations. However, lately it has been shrouded with confusion especially in the post COVID-19 crisis which prompted this study to investigate its current stature. The gradual disappearance of pandemic era gave birth to a new complex and challenging space for human resource management professionals in approximately 426 South African higher education institutions in both public and private sectors, who are compelled to find ingenious solutions around bringing sound and competitive organisational culture. Although there are vast studies that uncover different issues related to COVID-19 pandemic, few previous studies to date have been conducted regarding the change of organisational culture at the workplace in the post COVID-19 pandemic period. Since few prior studies have been carried out in both public and private academic institutions, the purpose of this study is to explore the organisational culture in the post COVID-19 pandemic period of South African Higher Education. The study utilised a qualitative research approach. In terms of data gathering, the phenomena were scoured for in journals using the desktop reviewing method. The desktop approach was used to find the answers to the research questions by consulting published literature, online databases, reports and online indexes. This assists to create a comprehensive understanding of the subject and propose a corrective plan of action.

Authors: Mohd Janjang Juliana , Mohd Nor Mohamed Yusoff , A. Hamid Aida Hanim
Published: November 2023

Compulsory education policies supported by the law have been implemented throughout the world for centuries, including in Malaysia. However, the implementation of the law is only limited to 6 years of compulsory education at the primary level as opposed to at the international level, which reaches a period of 8 to 12 years of compulsory schooling. Therefore, this study was conducted to explore the challenges faced by parents if Malaysia intends to implement compulsory education in Malaysia within a period of 12 years, starting from one year in preschool until the end of schooling at the secondary level. This study was conducted using a qualitative approach involving several participants selected through purposive sampling. The exploration results through open-ended questions, focus group discussions, and researcher notes were analysed using a thematic analysis, which then received expert consensus at an excellent level with a Cohen Kappa index value exceeding 0.81. The study discovered four themes of challenges faced by parents in implementing the 12-year compulsory education policy in Malaysia, namely parents' financial issues, school-related issues that are a challenge for parents, parents' difficulty in managing their children, and issues faced by children, all of which have resulted in challenges to parents. In this vein, these challenges should be emphasized because parents are the main implementers of the compulsory education policy, which also determines the success of the intended 12-year compulsory education policy.
AN ANALYSIS OF THE CONSTITUTIONAL PRINCIPLES OF EQUALITY AND AFFIRMATIVE ACTION VIS-À-VIS EMPLOYMENT IN MALAYSIA
Authors: Mohamad Amin Noor Shuhadawati , Mohd Badrol Afandi Nor Hafizah
Published: November 2023

Malaysia's diverse and multicultural society poses unique challenges in achieving a balanced and inclusive employment landscape that upholds both the rights and needs of individuals. In this regard, constitutional principles of equality serve as the cornerstone for promoting non-discrimination in employment across the public and private sectors. The concept of equality embedded in the constitution today, on the other hand, is anchored in a complicated historical context that has greatly shaped the nation’s path. Hence, guaranteeing the effective application of the principle while taking into account the individual rights and needs of every community remains a difficult challenge. This is because affirmative action policy is also embedded in the constitution that aims at protecting the Bumiputera. Hence, understanding the historical context behind the establishment of the constitution is of utmost importance as it allows Malaysians to appreciate its unique features that seek to strike a delicate balance between the rights and needs of the people. This study which is doctrinal in nature, attempts to examine Malaysia's constitutional equality principles, with a special emphasis on understanding how to strike a balance between individual's rights and needs in the context of employment. This study tries to uncover the issues and challenges that impede the equitable implementation of the equality principle in the employment sector by evaluating historical events, existing legal frameworks, policies, and practices.
The Digitalization Boost of the Covid‐19 Pandemic and Changes in Job Quality
Authors: Friedrich Teresa Sophie , Vicari Basha
Published: November 2023

The Covid‐19 pandemic caused a digitalization boost, mainly through the rise of telework. Even before the pandemic, advancing digital transformation restructured the way of working and thereby changed the quality of jobs—albeit at a different pace across occupations. With data from the German National Educational Panel Study (NEPS), we examine how job quality and the use of digital technologies changed during the first pandemic year in different occupations. Building on this, we analyze change score models to investigate how increased workplace digitalization connects to changes in selected aspects of employees’ subjective job quality. We find only a weak association between the digitalization boost in different occupational fields and the overall decrease in subjective job quality. However, telework—as one aspect of digitalization—is connected to a smaller decrease in work–family reconciliation and conformable working hours. Thus, it may buffer some detrimental pandemic effects on job quality. In addition, telework is connected to increased information overload, creating a new burden for specific employee groups.
Evaluation of Bacteriological Contamination Pattern of Open Fractures of Extremities- A Study from Tertiary Centre at Western India
Authors: Patel Vivek Amritbhai , Mendiratta Shlok
Published: November 2023

Background and Aim: In underdeveloped countries, open fractures are fairly prevalent. Open fractures can be caused by a variety of factors, including a car accident, a fall from a great height, a gunshot, an attack, machine injuries, and others. Infection is a typical side effect of open fractures. The goal of our study was to describe the pattern of bacterial contamination, antibiotic susceptibility, and possible antibiotic resistance in open fractures that arrived at our institute within 6 hours after injury. Material and Methods: A one-year prospective study was undertaken on 200 patients with open fractures of the extremities admitted to the accident and emergency department of Tertiary Care Teaching Institute of India. The first swab is obtained at the primary wound assessment, followed by the second culture swab shortly after debridement, the third culture swab on the day of the first aseptic dressing, and the fourth culture swab if the infection persists or the asepsis score is greater than 20 for a period of four days. Reports on culture and sensitivity were collected in order to analyse the pattern of bacterial isolates and their sensitivity. Results: The majority of the patients in this study were men (83%). We discovered 144 (72%) open fractures in the lower limb, with the tibia being the most often fractured bone, with 76 (38%) occurrences with right sided predominance (58%). Out of 200 patients, 78 (39%) had Gustilo II open fractures, followed by type IIIA (33%). Pre-debridement swabs were collected from all 200 patients with open fractures of the extremities upon admission. 26 (13%) of the patients were determined to be culture positive. Conclusion: In the therapy of patients with open fractures of the extremities, cultures acquired during the first aseptic dressing are considerably more predictive than pre- and post-debridement cultures, and are important in developing an antibiotic policy. It is thus recommended that cultures acquired during the first aseptic dressing provide direction in the selection of antimicrobial therapy, which, when paired with complete wound debridement, will allow for early wound closure and fewer problems.

Published: November 2023

Background. The effect of pharmacotherapy used to treat patients with the new coronavirus infection COVID-19 on immune parameters after treatment has not been sufficiently studied.
Aim. To study the effectiveness of pharmacotherapy and evaluate its impact on the immune response in patients with COVID-19.
Material and methods. The subjects of the study were 98 patients with COVID-19 aged from 32 to 68 years who were treated at the Penza Regional Clinical Center for Specialized Types of Medical Care from November 2022 to March 2023. The average age of the patients was 5018 years. Computed tomography revealed pneumonia in all patients (CT1CT4). The outpatient observation group included patients with COVID-19 (n=32), who were characterized by a mild course of the disease, 36 patients with moderate severity of COVID-19, and 30 patients with severe and extremely severe disease. Patients with mild COVID-19 received molnupiravir as antiviral therapy, patients with moderate COVID-19 received favipiravir, and patients with severe and extremely severe COVID-19 received remdesivir. After treatment, 72 patients were examined on an outpatient basis 34 weeks after discharge from the hospital. In the blood of patients before and after treatment, the populations of T- and B-lymphocytes, the functional activity of T-lymphocytes, cytokine indicators tumor necrosis factor , interleukins-4, -10 and -18, interferon in cell supernatants were studied. Statistical analysis of the groups was carried out according to Wilcoxon, differences were considered significantly significant at p 0.05.
Results. In the observation group (98 patients), in patients with mild disease (32 patients), recovery occurred in 31 (96.8%) people. With a moderate course of the disease, a favorable outcome with clinical and laboratory improvement was noted in 33 (91.7%) patients out of 36, and with a severe course of COVID-19 in 7 (23.4%) patients out of 30, 5 (16.6%) patients died, in 18 (60.0%) people after the 10th day of therapy complications from the cardiovascular system in the form of heart attacks and strokes were noted. After treatment in patients with COVID-19, the immune system showed an increase in the relative number of lymphocytes (p=0.034171), indicators of cytotoxic CD3+CD8+ T cells (p=0.001090), spontaneous synthesis of interferon (p=0.003246), induced production of interleukin-18 (p=0.003278), decrease in the absolute number of leukocytes (p=0.004319) and induced synthesis of interleukin-10 (p=0.042439).
Conclusion. Regardless of the type of antiviral therapy administered, a high recovery rate was recorded in patients with mild and moderate disease compared with severe and extremely severe disease.

Published: November 2023

BACKGROUND: The creation of new experimental models carrying various heterozygous inactivating mutations in DNA repair genes and their carcinogenesis studies could expand our understanding of the spectrum of possible neoplasms that patients with such mutations are at risk of developing.
AIM: The study of the effect of NBS1 inactivating heterozygous mutation (с.1971insT, p.Arg658Stop) in a model of 7,12-dimethylbenz[a]anthracene (DMBA) induced carcinogenesis in mice.
MATERIALS AND METHODS: Carcinogenesis was induced in 2-month-old female mice with and without NBS1 heterozygous mutation by intragastric administration of 7,12-DMBA (dose of 50 mg/kg once a week, for 8 weeks) on a high-fat diet. Lifetime observation was conducted, and parameters of lifespan and carcinogenesis were evaluated.
RESULTS: NBS1 inactivating heterozygous mutation had no significant effect on the incidence of tumor pathology induced by 7,12-DMBA, but somewhat accelerated the rate of tumor development and, consequently, the death of animals. The presence of the mutation increased the sensitivity to carcinogen toxic effect, which was expressed in a statistically significant increase in death rate (by 35%) in the early stages of the study. The mean lifespan in female NBS1 mutant mice was reduced by 14% compared to mutation-free animals.
CONCLUSION: Carrying NBS1 inactivating heterozygous mutation (с.1971insT, p.Arg658Stop) worsens the prognosis of survival in the model of chemically induced 7,12-DMBA carcinogenesis in mice.

Published: November 2023

he objectives of this study were to identify the clinical-epidemiological profile of patients undergoing radiotherapy for malignant neoplasia of the cervix; describe the main cytological changes induced by radiation during post-radiotherapy follow-up; verify the incidence of locoregional recurrence, according to the cytopathological diagnosis and identify the disease-free survival and overall survival of patients followed in the study. The methodological design had a descriptive approach with a quantitative nature and longitudinal character, whose population was composed of 407 patients with cervical cancer who underwent radiotherapy and were followed up for a minimum of 5 years and a maximum of 7 years. The project was approved by the Research Ethics Committee of the National Cancer Institute, Rio de Janeiro, Brazil. Sociodemographic variables and associated risk factors were evaluated; categorical variables (cytopathological) and dependent variables for the outcome of locoregional recurrence, death and disease-free survival. The epidemiological profile of the study population revealed a mean age of 51 years, with an age range primarily from 41 to 50 years, with risk factors associated with smoking being present in 32% of patients. The percentage of alcoholics was just 5.5%. Regarding the number of sexual partners, the average was 4 partners throughout life. Squamous cell carcinoma was the most common histological type (84%). Regarding clinical staging, 2B (42.9%) and 3B (33.7%) were predominant. Of the exams with satisfactory quality for analysis, more than half (64.9%) showed actinic effects. The incidence of locoregional recurrence, according to the cytopathological diagnosis, was 11.8%, of which almost half (47.9%) died. The analysis of locoregional recurrence that impacts disease-free survival was 69.5%. The overall survival found in the analyzed population was 75.7%. The difficulties related to actinic (radiotherapy) effects show the importance of the experience of professionals involved in the analysis of irradiated cells and reflection on the subjectivity of the method. Observing these changes is useful for evaluating the impact of actions taken during the period and planning future actions.
Increasing Pulse Foods in the Human Diet: A Qualitative Study
Authors: Robinson Julie , West Rebecca
Published: November 2023

Pulse foods are by definition the dry edible seeds of the botanical family Leguminosae. They include the common bean, chickpeas, lentils, and dry peas. The history of pulse use is briefly explored to illustrate the long and varied human traditions of pulse use through the centuries. Nutritional benefits include high protein, fiber, vitamins, and minerals. Pulses have also been studied for their positive effects on a number of chronic human health issues, such as cancer, diabetes, heart disease, obesity, blood pressure, and cholesterol. A description of pulse crops and their place in the agricultural environment illustrates how they are necessary for sustaining soil health, along with patterns of production and consumption worldwide. Health benefits of pulse foods consumption have been well established in the literature, but consumers remain reluctant to use them. The Dietary Guidelines for Americans as well as the Food-based Dietary Guidelines in Europe recommend at least two times weekly up to daily consumption of pulse foods, yet the vast majority of people fail to meet these minimums. In order to understand more fully the barriers to pulse consumption, a qualitative study was conducted by interviewing seven professionals who work with pulses across the spectrum of education, commodity organizations, research institutions, farming, and Cooperative Extension within a pulse-growing region of the U.S. Qualitative interviews using structured questions were conducted via Zoom with selected participants. A series of ten semi-open-ended questions were asked, including personal consumption habits of pulses, new pulse products on the market today, how the word “pulses” is understood or misunderstood by consumers, nutritional benefits, the role of MyPlate in helping consumers to plan meals with pulses, the types of consumers who eat pulses the most and what pulses they choose to eat, barriers to pulse use, and solutions for increasing and promoting pulse consumption. Data analysis found that there were a variety of reasons for the reluctance to use pulses, as well as the difficulty in marketing, research, and increasing production of pulses. Some solutions for promoting pulses could be implemented in the near future, and other solutions needed further research to implement.

Published: November 2023

The article analyzes the professional formation of the generation of philosophers who came to the Faculty of Philosophy of Moscow State University in the last years of the USSR and graduated from it already in the “new” Yeltsin’s Russia of the early 90s. In particular, the situation of general cultural lag in which several generations of Soviet and post-Soviet people found themselves in the context of world culture is thematized. By several examples, the thesis of the asynchrony of their acquaintance with the phenomena of Western culture at different levels and, as a result, falling out of the general logic of their formation is substantiated. The article also presents the history of the creation and development strategy of the philosophical journal “Logos” as a project to overcome the mentioned backlog. In conclusion, the authors attempt to explicate the ontological, epistemological and ethical-aesthetic foundations of their generational background.

Published: November 2023

Thalassia testudinum often dominates seagrass meadows of the Florida panhandle but few measurements of productivity, biomass, density, turnover or leaf area index in this region have been made. We targeted 5 estuaries located at similar latitudes, 30⁰ ± 0.3⁰N: Big Lagoon, Santa Rosa Sound, St. Andrew Bay, St. Joseph Bay, and St. George Sound. This study was one component of a collaborative partnership of state and local researchers examining factors preventing recovery in panhandle estuarine areas that had historically contained seagrass in the 1940s and 1950s. Measurements were made twice in 2016, once in June and then again in summer or fall, except in Santa Rosa Sound where measurements were made 3 times. In the estuaries sampled for the second time in July or August, aboveground productivity was greater than in June. St. Joseph Bay had the highest aboveground productivity (4.3 g/m2/d) and 1—sided leaf area index (4.2) while St. George Sound had the lowest values (0.41 g/m2/d and 1.0). Principal component analysis suggested that St. Andrew Bay, Big Lagoon and Santa Rosa Sound were the most similar, with higher values for shoot densities and leaf turnover and lower salinities and watershed:water ratios. St. Joseph Bay had high aboveground productivity and salinity, and low turbidity. St. George Sound had low aboveground productivity, high total suspended solids and the highest watershed:water ratio. These baseline productivity estimates will be useful to assess the success of restoration efforts targeting seagrasses in the Florida panhandle and evaluate impacts of climate change on seagrasses.

Published: November 2023

The authors proposed the consolidating method for analyzing series of observations based on a fitted model of a mixture of catalysts of the main components, which makes it possible to study any number of markers. Contrasting the longitudinal approach, it eliminates the need to connect regression analysis methods with their own uncertainties when choosing particular models. The consolidating method allows obtaining an original result in the subject area of early diagnosis of a disease: all options for using markers demonstrate an increase in classification accuracy with an increase in the length of a series of examinations.

Authors: Aryana I Gusti Ngurah Wien , Febyan  , Limena Shianita
Published: November 2023

Background: Osteoarthritis (OA) is a degenerative synovial joint disease with progressive pain and deformity. Stem cell therapy, especially mesenchymal stem cells (MSCs), has revolutionized the treatment of knee OA. However, clinical evidence for MSCs in the treatment of knee OA is insufficient. The primary objective of this research is to offer substantiation and recommendations for advancing and utilizing MSC therapy in clinical settings, in contrast to the use of hyaluronic acid (HA) as the standard control group.Methods: This study was a meta-analysis conducted through a search for relevant scientific reports in PubMed, Embase, and Google Scholar, using some keywords such as "mesenchymal stem cell," "hyaluronic acid," and "osteoarthritis." Results: Mesenchymal stem cells showed promising results on a clinical basis. Among five included studies of 139 patients with knee osteoarthritis consisting of 70 patients treated with MSC and 69 patients treated with HA, mesenchymal stem cells provide significant short-term pain relief at 6- (I2=34%; SMD=-0.58 95% CI, -1.09 to -0.07; p=0.02) and 12-months follow-up (I2=28%; SMD=-0.79 95% CI, -1.22 to -0.37; p=0.0003), with relative clinical improvement. The highly differentiated MSC aids in tissue repair, regulation of immune response, and anti-inflammatory effect on knee osteoarthritis, including the chondrogenesis mechanism.Conclusion: Mesenchymal stem cell therapy has shown effectiveness compared to hyaluronic acid injection for knee osteoarthritis, providing pain relief and improved functional outcomes on short-term intervals up to 12 months follow-up. Mesenchymal stem cells display some chondroprotective effects requiring further research and development.

Published: November 2023

Introductions: One of the mental health disorders that have an impact on physical health is called somatization disorder. Somatization is characterized by the appearance of complaints of pain in body parts that occur repeatedly. Anxiety, various physical complaints, and an increasing number of symptoms accompany symptoms of somatization disorder. The most common physical complaint is heartburn. Case: This case report discusses the case of a 36-year-old woman who complained of heartburn by visiting various doctors, but no medical results showed any abnormalities. Purpose: This case report aims to provide a literature review of heartburn symptoms due to somatization. Discussion: The Relationship between Heartburn Levels and Somatoform Disorders Psychosocial stressors are related to psychological factors that influence medical conditions that cause prominent psychological and somatic disorders. Psychological disorders and vice versa can cause physical disturbances. The patient’s bodily medical condition can cause psychological disorders. Patients with severe acute pain will experience anxiety, fear, and sleep disturbances. This is due to the patient’s discomfort with his condition, where he suffers from the pain he experiences and cannot move. With increasing duration and intensity of pain, the patient may experience a depressive disorder, and then the patient will be frustrated and irritable towards those around him and himself. Conclusion: The high pain intensity in the patient will cause sensitivity and increase his concern for his physical, lowering the threshold for detecting physical sensations or expressing distress and pain.

Introductions: Mental disorders are a group of symptoms that co-occur in individuals at a particular time. Symptoms of mental disorders can include physical, biological, psychological, and cognitive symptoms. Mental disorders are considered a silent epidemic in rural areas. This condition is caused by the lack of access to health service centers, especially in the 3T areas (Tertinggal, Terdepan dan Terluar) or fall behind, frontier, and outermost. Wakatobi Regency is one of the regencies in Southeast Sulawesi Province, which has 142 islands and is included in the 3T area. Objective: This study aims to determine the sociodemographic description and its relationship with psychopathology in Wanci Village, Wakatobi Regency residents. Methods: This research is included in the cross-sectional survey using an accidental sampling technique. Respondents amounted to 46 people who have fulfilled the requirements. The research instrument used was the Self Reporting Questionnaire-20 (SRQ-20). Results: A total of 46 samples included in the inclusion criteria found that 22 respondents (47.8%) had SRQ-20 values ≥6 or experienced mental-emotional disorders. In bivariate analysis using chi-square tests, significant results were obtained (P<0.05) for age (P=0.029) and spouse (P=0.035). Conclusion: In this study, it was found that there was a statistically significant relationship between age and spouse variables on psychopathology.

Lithium-ion batteries (LIBs) are the predominant power source for portable electronic devices, and in recent years, their use has extended to higher-energy and larger devices. However, to satisfy the stringent requirements of safety and energy density, further material advancements are required. Due to the inherent flammability and incompatibility of organic solvent-based liquid electrolytes with materials utilized in high energy devices, it is necessary to transition to alternative conductive mediums. The focus is shifting from molecular materials to a class of materials based on ions, including ionic liquids (ILs) and their derivatives such as zwitterionic ILs, polymerized ILs, and solvated ILs, which possess high levels of safety, stability, compatibility, and the ability to rationally design ILs for specific applications. Ion design is crucial to achieve superior control of electrode/electrolyte interphases (EEIs) both on anode and cathode surfaces to realize safer and higher-energy lithium-metal batteries (LMBs). This review summarizes the different uses of ILs in electrolytes (both liquid and solids) for LMBs, reporting the most promising results obtained during the last years and highlighting their role in the formation of suitable EEIs. Furthermore, a discussion on the use of deep-eutectic solvents is also provided, which is a class of material with similar properties to ILs and an important alternative from the viewpoint of sustainability. Lastly, future prospects for the optimization of IL-based electrolytes are summarized, ranging from the functional design of ionic structures to the realization of nanophases with specific features.

Mechanoluminescence is the phenomenon in which certain materials emit light when subjected to mechanical stimuli, such as bending, stretching, or compression. Soft devices containing embedded mechanoluminescent materials are capable of responding to mechanical deformation by emitting light, which can be utilized for various applications, including sensing, display, communication, and visual feedback. In this Perspective, we discuss recent advancements and emerging applications of mechanoluminescent materials for soft devices, with a focus on the remaining challenges in mechanoluminescent materials, such as performance, mechanism, synthesis, and device fabrication, that need to be addressed for developing advanced soft devices, and propose the potential solutions.

Purpose ― This study aims to investigate the impact of FDI inflows on Trade in Azerbaijan from 1993 to 2021. Method ― This study uses the datasets from the World Bank Database. It employs the Augmented Dickey and Fuller (ADF), Phillips and Perron (PP), Zivot and Andrews (ZA), ARDL bounds testing approach, and the Granger Causality tests for the empirical part of the study.Findings ― The bound test shows the presence of cointegration between FDI and Export. The estimated long-run equation suggests a positive and significant relationship, whereas the estimated short-run equation indicates a positive but insignificant relationship between FDI and export. Additionally, the results of Granger causality test show a unidirectional causality running from FDI to export. Implications ― Since the FDI inflows show a positive effect on the export of Azerbaijan, most foreign investments come into the oil and gas sector. Accordingly, oil and gas products and services account for a significant share of exports in Azerbaijan. Policymakers might need new regulations to attract more attention from foreign investors to non-oil sectors.Originality/value ― There were vast studies about FDI and trade relationships in different countries with different techniques. This study is unique because it employs a new methodology and the latest dataset in which Azerbaijan was a focused area for the first time.

Any-to-One Non-Parallel Voice Conversion System Using an Autoregressive Conversion Model and LPCNet Vocoder

Published: November 2023

We present an any-to-one voice conversion (VC) system, using an autoregressive model and LPCNet vocoder, aimed to enhance the converted speech in terms of naturalness, intelligibility, and speaker similarity. As the name implies, non-parallel any-to-one voice conversion does not require paired source and target speeches and can be employed for arbitrary speech conversion tasks. Recent advancements in neural-based vocoders, such as WaveNet, have improved the efficiency of speech synthesis. However, in practice, we find that the trajectory of some generated waveforms is not consistently smooth, leading to occasional voice errors. To address this issue, we propose to use an autoregressive (AR) conversion model along with the high-fidelity LPCNet vocoder. This combination not only solves the problems of waveform fluidity but also produces more natural and clear speech, with the added capability of real-time speech generation. To precisely represent the linguistic content of a given utterance, we use speaker-independent PPG features (SI-PPG) computed from an automatic speech recognition (ASR) model trained on a multi-speaker corpus. Next, a conversion model maps the SI-PPG to the acoustic representations used as input features for the LPCNet. The proposed autoregressive structure enables our system to produce the following prediction step outputs from the acoustic features predicted in the previous step. We evaluate the effectiveness of our system by performing any-to-one conversion pairs between native English speakers. Experimental results show that the proposed method outperforms state-of-the-art systems, producing higher speech quality and greater speaker similarity.

Published: November 2023

Life Cycle Assessment (LCA) methodology is increasingly prevalent in the quantification of environmental status in the building sector, following new legislative frameworks. Countries need to quantify and assess their environmental impacts as a previous base for regulation and decision making. In this context, standardised national data sets are being developed, based on consensus with manufacturers: sectoral Environmental Product Declarations. This study focuses on assessing these EPDs with the aim of providing relevant information for global decision-making, focusing on consistency and pointing out shortcomings. An assessment has been carried out both at national level, considering all sectoral EPDs and declared products, and at international level, with three common building materials (brick, steel and concrete). The results highlight the lack of traceability in the development and assessment of uncertainty, resulting in substantial discrepancies in reported impacts, especially in the later stages of the life cycle (up to 90% difference). Meanwhile, impacts such as Global Warming Potential or total renewable and non-renewable primary energy use show homogeneous values in the cradle-to-gate stages with differences generally less than 10%. The analysis of sectoral EPDs should be a design guide with environmental sustainability criteria, as the last section of this study attempts to focus on.

Published: November 2023

Protein tyrosine phosphatases (PTPs) of the polymerase and histidinol phosphatases (PHP) superfamily with characteristic phosphatase activity dependent on divalent metal ions are found in many gram-positive bacteria. Although members of this family are co-purified with metal ions, they still require the exogenous supply of metal ions for full activation. However, the specific roles these metal ions play during catalysis are yet to be well understood. Here, we report the metal ion requirement for phosphatase activities of S. aureus Cap8C and L. rhamnosus Wzb. AlphaFold-predicted structures of the two PTPs suggest that they are members of the PHP family. Like other PHP phosphatases, the two enzymes have catalytic preference for Mn2+, Co2+, and Ni2+ ions. Cap8C and Wzb show an unusual thermophilic property with optimum activities over 75oC. Pre-incubation experiments show that the two enzymes are not inherently thermostable suggesting that certain catalytic step(s) in the reaction mechanism has a high activation energy. Consistent with this model, the activity-temperature profiles of the two enzymes are dependent on the divalent metal ion activating the enzyme.
