Authors: Zhan Shaoquan , Mao Yuling , Kang Xiangjin , Lin Han , Li Sichen , Li Li , Ying Ying , Liu Hanyan
Published: November 2022

Background: Evaluating the efficacy and safety of ovarian stimulation protocols is beneficial for infertile patients undergoing in vitro fertilization (IVF). The mild ovarian stimulation-IVF (m-IVF) protocol using clomiphene citrate is considered to have better neonatal outcomes in fresh cycles; however, few studies have evaluated the neonatal outcomes in frozen-thawed embryo transfer (FET) cycles. Therefore, we aimed to compare the neonatal risks following fresh embryo transfer (ET) and FET between m-IVF and conventional IVF protocols.
Methods: The baseline characteristics, treatment, and clinical outcomes of the cohorts from January, 2013 to December, 2020 were compared using propensity score matching analysis. All singleton pregnancies and live births from m-IVF (n = 129 in fresh ET, n = 522 in FET) and long gonadotropin-releasing hormone agonist (GnRH-a; n = 301 in fresh ET, n = 1057 in FET) protocol cycles were analyzed to compare the primary outcomes, including mean birth weight (BW), small for gestational age (SGA), and large for gestational age (LGA). Logistic regression was used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for SGA and LGA.
Results: The mean BW of m-IVF infants was slightly higher than that of conventional IVF infants with fresh ET (P > 0.05). In the FET group, the incidence of SGA (7.85 vs. 4.64%) and LGA (13.79 vs. 18.83%) was significantly different between the m-IVF and long GnRH-a groups (P < 0.05). Further analysis revealed that the occurrence of SGA was related to the stage of embryo transfer (aOR = 0.67, 95% CI = 0.46–0.98) and female infants (aOR = 2.02, 95% CI = 1.38–2.96), and the occurrence of LGA was related to maternal body mass index (BMI; aOR = 1.68, 95% CI = 1.30–2.17 for ≥24 kg/m2), blastocyst transfer (aOR = 1.44, 95% CI = 1.09–1.90), male infants (aOR = 1.84, 95% CI = 1.42–2.38), and FET (aOR = 1.69, 95% CI = 1.12–2.53).
Conclusions: SGA was associated with cleavage embryo transfer and female infants, but not with ovarian stimulation protocols. Similarly, LGA was associated with maternal BMI, blastocyst transfer, male infants, and FET, but not with the ovarian stimulation protocols.
Pythagoras–Born: on a relationship between the quantum and the classical
Authors: Brezhnev Yurii V.
Published: November 2022

The genesis of the Hilbert-space mathematics in quantum theory continues to raise questions, and a characteristic feature of this space is a mod-squaring the quantum states. However, superposition principleea cornerstone of quantum interferenceedoes not refer to the Born–Hilbert square per se. This ‘two ||···|| 2 ’ can be derived without resorting to the Hilbertian/quantum math: norm, scalar product, and operators. We show here that this point has an immediate corollary for the elementary scholastic geometry; the square has an explanation. The Pythagoras theorem and the square-root dependence for length become the deducible constructs. Quantum analogies turn this ancient theorem into a derivable definition, so the Pythagorean and Bornian twos have almost identical origin. The metric geometry and the concepts of inner product, of orthogonality, of (right) angle, etc are also the derivatives.
Irregular Rupture Process of the 2022 Taitung, Taiwan, Earthquake Sequence
Authors: Yagi Yuji , Okuwaki Ryo , Enescu Bogdan , Lu Junjie
Published: November 2022

In September 2022, two destructive earthquakes of moment magnitude (Mw) 6.6 (foreshock) and 7.1 (mainshock) occurred in Taitung County, south-eastern Taiwan. To understand their complex rupture processes, we analysed these earthquakes using the Potency Density Tensor Inversion method, which can stably estimate the rupture propagation process, including fault geometry, without overfitting the data. The analyses revealed that the major rupture of the foreshock propagated towards shallow depth, in a south-southwest direction, following an initial rupture that propagated towards the deeper part of the fault. The mainshock, with its epicentre on the north-northeast side of that of the foreshock, consists of two distinct episodes. During the first episode (0–10 s), the initial rupture propagated north-northeast, through a deep path, followed by the main rupture that propagated bilaterally in a north-northeast and south-southwest direction. The second rupture episode (10–16 s) started near the hypocentre of the mainshock, and the rupture propagated towards the shallow side of the fault. The results suggest that the stress concentration from both the foreshock and mainshock’s first rupture episode may have caused the second rupture episode in the high fracture surface energy area between the foreshock and the first rupture episode of the mainshock. The irregular rupture process of the foreshock and mainshock may reflect the heterogeneity of stress and structure in the source region.

Published: November 2022

Considering the propagation characteristics of COVID-19 in different regions, the dynamics analysis and numerical demonstration of long-term and short-term models of COVID-19 are carried out, respectively. The long-term model is devoted to investigate the global stability of COVID-19 model with asymptomatic infections and quarantine measures. By using the limit system of the model and Lyapunov function method, it is shown that the COVID-19-free equilibrium V 0 is globally asymptotically stable if the control reproduction number Rc < 1 and globally attractive if Rc = 1, which means that COVID-19 will die out; the COVID-19 equilibrium V∗ is globally asymptotically stable if Rc > 1, which means that COVID-19 will be persistent. In particular, to obtain the local stability of V∗ , we use proof by contradiction and the properties of complex modulus with some novel details, and we prove the weak persistence of the system to obtain the global attractivity of V∗ . Moreover, the final size of the corresponding short-term model is calculated and the stability of its multiple equilibria is analyzed. Numerical simulations of COVID-19 cases show that quarantine measures and asymptomatic infections have a non-negligible impact on the transmission of COVID-19

Published: November 2022

In finance, machine learning helps the business by improving its abilities and flexibility to prevent risks, errors and to accept such challenges. This research analyses and forecasts the interest rate risk of Pakistan using machine learning models. It took the financial dataset of 10 years Pakistan investment bonds from the State Bank of Pakistan website. In this study, a framework was proposed and four different models were developed to forecast the interest rates: Neural Network, Bootstrap Aggregated Regression Trees, Cascade-Forward Neural Network, and Radial Basis Neural Network. Subsequently, these models were run under four different scenarios: Forecasting with Original, Generated, LASSO extracted and Weighted Average features. In addition, the outcomes of these models were compared with four performance metrics: Mean Absolute Percentage Error, Daily Peak Mean Absolute Percentage Error, Mean Absolute Error, and Root Mean Square Error. Overall, the results showed that Radial Basis Neural Network provided the best forecasting.
Heterogeneous Parallel Implementation of PSO Algorithm with an Aging Leader and Challengers
Authors: Yazdanpanah Fahimeh
Published: November 2022

Parallel computing techniques provide high-performance execution of large-size and real-world complicated problems such as heuristic optimization algorithms. One of the most popular optimization algorithms is PSO (particle swarm optimization) which is an intelligent search method for finding the best solution according to population state. The PSO algorithm has obtained significant attention from researchers and different parallel implementations of this algorithm have been presented for intensive-computing applications. The ALC-PSO algorithm (PSO with an aging leader and challengers) is an improved population-based and intensive-computation procedure thanks to the high fitness analyses. Compared to the traditional PSO, the ALC-PSO algorithm improves convergence rapidity. In this paper, we have developed a novel heterogeneous parallel implementation of the ALC-PSO algorithm using OmpSs and CUDA, for execution on both CPU and GPU cores. OmpSs is a task-based parallel programming model that uses runtime system and hardware for automatic exploiting and managing parallelisms. Combination of OmpSs with CUDA helps developers accelerate their applications running on both CPUs and GPUs. The results demonstrate that the proposed approach (i.e., the OmpSs-CUDA implementation of the ALC-PSO algorithm) provides higher performance than the serial, and also the CUDA-based parallel implementations of the ALC-PSO algorithm.

Design and Implementation of a Bidirectional High Step-up, reduced Normalized Peak Inverse Voltage with Better Current Balancing Function DC-DC Multi-Port Converter with Reduced Elements Ratings and Count
Authors: Kumar B. Ashok , Ezhilarasi.G Angeline
Published: November 2022

In this paper, high-step-up, non-isolated, non-coupled, inductor-based, connected multi-port dc-dc converters for photovoltaic (PV) and battery applications are presented with a decreased component count. The use of the converter in future applications of sustainable energy systems is the focus of this study, the objective of which is to achieve this objective. The proposed topology takes on some of the beneficial qualities of the traditional multi-port architecture, such as voltage gain proportional to the number of connected devices, and even power-sharing in open-loop as a newly added function. To provide the same amount of voltage gain with fewer devices and lower element ratings is possible with the proposed topology. This results in a reduction in the system's overall cost as well as its size, weight, and level of complexity. It is capable of achieving a higher power density of voltage in comparison to existing converters that possess a current-balancing function and reduced Normalized Peak Inverse Voltage on switches and diodes as a result of the elimination of the need for an auxiliary magnetic circuit or complex control scheme in order to equalize the shared power, and it is able to do all of these things simultaneously. In addition to the demagnetization and magnetic short-circuit difficulties that were previously associated with traditional converters but have now been eliminated, decoupled power flow management can now be achieved under any and all circumstances. The energy from the load is able to be taken in and stored in the first input unit. Other advantages of the suggested topology include its modularity and simple structure, as well as its continuous input currents and low input current ripple. Applications requiring low to medium amounts of power are recommended for the structure that is being proposed. The proposed topology has been broken down, and both operational modes and steady-state analyses have been covered. The proposed topology has been evaluated against a number of different multi-port high-gain converters so that verification can be improved. The results of the comparison show that the proposed topology has several advantages.

Published: November 2022

Stormwater control measures (SCMs) are effective and sustainable complementary means of managing stormwater in cities. Unlike underground drainage systems, they require space on the city surface, and therefore must be included in initial sketches of urban planning and design. These initial sketches are often made by architects and urban planners, who are usually not trained in hydrology, and therefore require simple and robust tools to inform their initial plans with respect to stormwater management. There may be local guidelines for dimensioning SCMs, but their applicability is often limited with regard to the range of SCMs, and the methodology behind them may be oversimplified, including a lack of assessment of benefits on the urban hydrological cycle. We developed a methodology for estimating multiple performance indicators of a wide range of SCMs and applied it to Danish meteorological conditions. The methodology includes consulting expected end users, configuring an SWMM model for each SCM type and choosing applicable parameter ranges, running multiple simulations for each type covering the parameter space, and post-processing the results using python and PySWMM. The outputs can be used to draw general recommendations regarding effective application ranges for different SCMs, and to quickly assess the performance of case-specific configurations.

Authors: Cheng Zhe , Yan Shuo , Song Tao , Cheng Le , Wang Huanming
Published: November 2022

Adaptive water governance plays an increasingly important role in sustainable urban development and water governance response to global climate change. To comprehensively understand the research situation and development trend of adaptive water management, this study conducts a systematic literature review of articles published in International Social Sciences Citation Index (SSCI) journals based on bibliometric analysis. The results show that adaptive water governance as an emerging topic of water governance has an overall growth trend in published articles. The articles on adaptive water governance mainly concentrated on the disciplines of environmental science and environmental studies. Developed countries are a hub for water governance research, and China has the sixth largest number of articles from around the world. The adaptive water governance research has formed a preliminary global collaborative network, but the authors' collaboration needs to be strengthened. The most popular topics of adaptive water governance include South Africa, adaptive management, groundwater, principal component analysis, scenario planning, the analytic hierarchy process, resources, basins, computer experiments, and technology development. This finding suggests that adaptive water governance is a critical driver for sustainable urban development and represents a critical direction in the future research of water governance.
Gut Microbiome and Insomnia: A Mini-Review
Authors: Yaser Asaad Noor , Walid Ballan Maram , Shalabi Heba Yead Abdel-Latif , Hossain Ashfaque
Published: November 2022

Background:

The gut microbiome (microorganisms present in our gut) has emerged as an important determinative factor in a variety of diseases and health
conditions. One new area in which the role of the gut microbiome is of intense interest is its role in various neurological manifestations, including
insomnia, the most common sleep disorder. In this mini-review, we aim to highlight the latest research developments concerning the association
between the gut microbiome and insomnia and summarize gut-brain interaction for a better understanding of the role of microbiota in insomnia.

Methods:

Our search results included publications written in English from the year 2010 up to the year 2022. We used Pubmed, Google Scholar, and ScienceDirect to search for original articles pertaining to the relationship between the gut microbiome and insomnia using the following search terms: "Gut-brain Axis and Insomnia," "Brain and Gut Microbiome," " Gut-brain Homeostasis”, and "Circadian Rhythm and Gut Microbiome". Relevant articles from the reference list were reviewed in order to collect additional information.

Results:

Studies have shown that the microbiome-gut-brain axis is thus associated with the development of insomnia. The gut microbiome can have an
important role in the development of insomnia. On the other hand, insomnia can also modulate the gut microbiome. However, scientific work in
this field is limited as relevant scientific research is at the initial state.

Conclusion:

Bacteria present in the gut send signals to the brain via the vagus nerve by stimulating the afferent neurons of the enteric nervous system and
influencing sleep quality and stress reactivity of the hypothalamic-pituitary-adrenal axis. The gut microbiome also communicates with the nervous
system via the neuroendocrine pathway through various metabolic products. Insomnia also influences the structure and function of the gut
microbiome.
A Novel Powerful γ-Fe2O3 @ CPTMS - Diethylene Triamine (DETA)
@SO3H as a Heterogeneous Nanocatalyst, Recyclable and Efficient via
Microwave-assisted for the Synthesis of Benzoxazinone- 4(3H)-one Derivatives
in Green Media
Authors: Norouzi Fateme Haji , Foroughifar Naser , Khajeh-Amiri Alireza , Pasdar Hoda
Published: November 2022

Background:

In order to synthesize benzoxazin-4 (3H) -one derivatives, a new inorganic-
organic super-magnetic nano-hybrid (γ‐Fe2O3@ CPTMS-DETA @SO3H) nanocatalyst of the
modified sulfuric acid represents a green and efficient catalyst to perform a three-component condensation
reaction between various acyl chlorides, anthranilic acid and acetic anhydride (as cyclization
agent), in one-pot and solvent-free conditions under microwave irradiation (4a-q).

Introduction:

In recent years, one of the most important subjects in synthetic organic chemistry
has been green synthesis, which has applied environmentally friendly and efficient methods to
synthesize biological derivatives. The use of catalysts has significant advantages, including simple
separation and preparation, chemical and thermal stability, and eco-friendly nature and their features
such as reusability, low cost, high efficiency and easy operation. Therefore, the mechanism
is performed by a non-toxic organic catalyst that uses the chemical reactants and the least energy
in accordance based on the least waste and green chemistry.

Methods:

Sequential addition and one-pot methods were applied to produce benzoxazinone derivatives.
In the sequential addition approach, the reaction was begun by adding anthranilic acid and
acetic anhydride to the reaction vessel under microwave irradiation and continued by adding γ‐
Fe2O3@ CPTMS-DETA @SO3H as super-magnetic nano-hybrid recyclable green catalysts and
the desired acyl chlorides.

Results:

The main objective of this project was to synthesize benzoxazin-4 (3H) -one derivatives
in the presence of super-paramagnetic organic-inorganic nanohybrid particles based on improved
sulfonic acid (γ- Fe2O3 @ SiO2 - DETA @ SO3H) as an efficient recyclable heterogeneous catalyst.

Conclusion:

This paramagnetic nano-organocatalyst was characterized by EDX, VSM, TGA, FESEM,
FT-IR, and XRD. Advantages of this catalyst include easy preparation, clear and easy operation,
short reaction time (15–30 min), as well as without the use of toxic catalysts. In addition,
the catalyst can be separated from the reaction solution using an external magnet by magnetic decantation;
it can be recycled up to six times without reducing its activity.

Leukocyte Count and Neutrophil-To-Lymphocyte Ratio as Simple Hematologic Predictors of Stroke Severity and Functional Outcome in Acute Ischemic Stroke Patients
Authors: Pinzon Rizaldy Taslim , Veronica Vanessa
Published: November 2022

Background:

It has long been recognized that inflammation plays a critical role in the pathogenesis of ischemic stroke. However, whether leukocyte count and neutrophil-to-lymphocyte ratio are related to stroke severity and functional outcome is uncertain.

Objective:

This clinical study aimed to evaluate the association of leukocyte count and neutrophil-to-lymphocyte ratio with stroke severity and functional outcome in acute ischemic stroke patients.

Methods:

This hospital-based, retrospective observational study included 112 subjects with acute ischemic stroke. All subjects had their demographic, clinical, and laboratory data obtained. The leukocyte count and neutrophil-to-lymphocyte ratio were evaluated by stroke severity on admission and 3-month functional outcome. The severity of stroke at admission was measured using the National Institutes of Health Stroke Scale (NIHSS), whereas the Barthel Index was used to measure 3-month functional outcome (BI). We conducted a regression analysis, adjusting for any confounding variables.

Results:

Higher leukocyte count was significantly associated with increased risk of stroke severity (odds ratio [OR] 1.391, 95% confidence intervals [CI], 1.121-1.725, p: 0.003) and unfavorable functional outcome (OR 1.434, 95% CI, 1.068-1.925, p: 0.017). Higher neutrophil-to-lymphocyte ratio was not significantly associated with increased risk of stroke severity (OR 1.181, 95% CI, 0.947-1.474, p: 0.140) and unfavorable functional outcome (OR 1.246, 95% CI, 0.905-1.716, p: 0.177).

Conclusion:

Our study indicates that leukocyte count is an independent predictor of stroke severity on admission and unfavorable functional outcome.
Comparison of Sub-epithelial Connective Tissue Graft and Platelet Rich Fibrin in Peri-implant Soft Tissue Augmentation: A Randomized Clinical Split-Mouth Study
Authors: Elkashty Ayman Abdel-Rahim , Aboelmaaty Wael Mohammed , Helmy Samah Mohammed , Elewa Mohammed Elsaed , Mansour Alaa , Ateia Islam Mohammed
Published: November 2022

Aims and Background:

Gingival phenotype has a crucial impact on the peri-implant marginal bone stability. The aim of this clinical trial is to assess and compare the efficacy of the sub-epithelial connective tissue graft (SCTG) and platelet-rich fibrin (PRF) in improving the peri-implant soft tissue phenotype and enhancing esthetic outcomes.

Material and Methods:

The present study was a split-mouth randomized controlled clinical trial. A total of ten patients who had bilateral missing teeth in the maxillary esthetic zone with a thin gingival phenotype were included in this study. For each study participant, one randomly selected site was treated with SCTG while the other was treated with PRF membrane during dental implant placement. Treatment outcomes included the assessment of the facial gingival thickness using cone-beam computed tomography (CBCT) at the baseline (T0) and 6 months postoperatively (T1), and the Pink esthetic score (PES) at T1 and 3 months later after prosthesis placement (T2).

Results and discussion:

Both treatment options resulted in a significant increase in gingival tissue thickness at T1 compared with T0, and in PES at T2 compared with T1 (p ˂ 0.05).

Conclusion:

PRF is an effective alternative to SCTG in augmenting peri-implant soft tissue phenotype and improving the esthetic outcomes. This would help overcome the complications associated with harvesting the SCTG and increasing patients’ satisfaction.
Tempos e temporalidades Contribuições para a descrição do ‘comentário’ como género
Authors: Coutinho Antónia , Correia Clara Nunes
Published: November 2022

Grammatical tenses contribute to the characterization of temporality that is present in different texts and discourses. This observation is the starting point of the reflection presented in this paper. Thus, based on texts that circulate with the label ‘commentary’, we propose to verify how linguistic marks (used in the different forms and constructions of those texts) contribute to a description of what is (or could be) a commentary. We start with the analysis of texts that are available in the corpus G&T.Comentaand we attempt to characterize the values of grammatical tenses in Portuguese, and the temporal locators that contribute to the construction of temporality in those texts. This approach allows for relating textual genres and types of discourse (Bronckart, 1997). The proposals developed within the scope of Sociodiscursive Interactionism will be followed as a guiding principle.To account in a sustainable way for the values that derive from the various grammatical tenses used in those texts, we will consider the proposals that were developed within the perspective of the Enunciative Formal Theory (Culioli 1995), among others. Based on this framework, it is assumed that the different values characterizing grammatical tenses derive from the interrelation between different grammatical categories such as aspect and modality.The relationships that can be established in the articulation between a micro analysis (centered on forms and constructions) and a macro analysis (which captures the text as a complex whole), will allow us to contribute to a characterization that we consider useful not only for defining properties of texts that are included in the commentary genre, but also for defining the values of grammatical tenses.
Evidencialidade/mediatividade, modalidade epistémica e (inter)subjetividade
Authors: Silva Augusto Soares da
Published: November 2022

Evidentiality or, following the French linguistic tradition, “mediativity” is a complex and controversial category, with an already extensive body of literature devoted to other languages and a few studies focusing on Portuguese. As a conceptual category, abstracting away from its linguistic means of expression, which is to some extent present in languages such as Portuguese that lack a specific grammatical system for its codification, evidentiality/mediativity raises two main issues which are yet to be addressed: the first question concerns the definition of its status as a grammatical, semantic or discursive category and of its conceptual basis, traditionally characterized as referring to the source of information for the propositional content of the utterance, while the second touches upon its demarcation with respect to the conceptual category of epistemic modality. The aim of this study is to provide an answer to both questions from a cognitive-functional, usage-based perspective, on the basis of two grammaticalized evidential/mediative markers of Portuguese, namely the compound form of the future and the verb parecer ‘seem’ followed by a non-finite verb or a finite clause. We sustain the view that evidentiality provides an indication about the source and reliability of the information, and that reliability does not necessarily involve degrees of epistemic speaker commitment or degrees of (un)certainty. While the reportative evidential uses of the compound form of the future in Modern European Portuguese, typical of news reports, and of parecer provide evidence for the relative independence of evidentiality in relation to epistemic modality, the inferential evidential uses of the compound future and of parecer reveal a close link, and even a partial overlap, between evidentiality and epistemic modality. Both reportative and inferential uses of these evidential markers contribute to the speaker’s epistemic control in the discourse and speaker’s intersubjective alignment. While the inferential uses of the compound future and of parecer stemmed from diachronic cognitive and pragmatic-discursive processes of subjectification, the reportative uses of these evidential markers resulted from diachronic cognitive and pragmatic-discursive processes of intersubjectification.
Chacun en portugais et cada qual en français diversification et neutralisation
Authors: Bacquelaine Françoise
Published: November 2022

Portuguese and French language systems have many common features, but it is well-known that each language has its peculiarities. The asymmetry between the universal quantifier pronoun chacun in French and the three Portuguese pronouns cada um, cada qual and cada raises challenges of equivalence between these two Romance languages. Choosing a Portuguese equivalent of chacun presents the translator with a challenge that Koller (1992) refers to as ‘diversification’ (one-to-many relationship). Conversely, choosing a French equivalent of cada qual results in a loss of its peculiar features compared to cada um (the most frequent) and the exclusively floating quantifier cada. This ‘neutralisation’ (several-to-one relationship) can be compensated for by the translator (ibid.). Admittedly, cada qual is much rarer than cada um, but this pronoun is very intriguing for a French speaker, who wonders how professional translators in search of equivalence react when confronted to diversification of chacun and neutralisation of cada qual. The analysis of two aligned bilingual corpora consisting of FR-PT segments (translation memories) provides some answers to these questions. The first one consists of 378 segments containing chacun and its Portuguese equivalents. These segments were extracted from a journalistic corpus (MondeDiplomatique.v1, Per-Fide 2012). The second consists of 89 segments containing cadaqual and its French equivalents. These segments come from translation memories of EU institutions, also made available to the public by the Per-Fide project. Not surprisingly, cada um is the most frequent equivalent of chacunand chacun is the most frequent equivalent of cada qual. But the solutions to the challenges raised by diversification and neutralisation are varied and even go beyond the framework of universal quantification. This finding confirms the diversity of factors involved in the choices of professional translators.
El lugar de la competencia digital en la enseñanza y aprendizaje de lenguas segundas y extranjeras

The globalized Information Society that has been taking shape in the 21st century with advances in new technologies requires its members to have a series of key skills, among which digital competence stands out as part of the capacity for permanent and autonomous learning. The Covid pandemic that we have been going through for almost three years has highlighted the need to train people in digital competence in order to continue carrying out their personal, educational and professional activities in all kinds of contexts and circumstances. The consultation of catalogues, bibliometric databases and digital repositories, such as Scopus, Dialnet or Recolecta, has allowed us to verify the interests that the subject arouses in the scientific community, particularly within the area of education. Thus, there is interest in identifying those digital skills that the teacher must master, in outlining the ICT skills that students need to acquire at each educational level, or in developing activities based on the specific use of applications or digital resources (use of blogs, wikis, social networks, gamification, etc.) for second and foreign language teaching.Using a fundamentally qualitative methodology, with a descriptive-interpretative epistemological orientation based on documentary analysis, the objective of this paper is to analyse the concept of digital competence and verify the place it occupies in the process of second and foreign language acquisition, especially following the publication of the complementary volume of the Common European Framework of Reference for Languages: Learning, Teaching, Assessment (CEFR) in 2020. To this end, a conceptual delimitation has been introduced between competence digital and a series of concepts related to it, such as digital literacy, information literacy or media competence, very present in contemporary academic, scientific, political and economic discourse; the concept of digital competence, understood as a macrocompetence, has been organized in the various (sub)competences it is made up of, and we examine the place that digital competence occupies in each person’s set of competences and in relation to the communication skills, mainly within the field of second and foreign language acquisition. After this systematic review, we conclude that, although the contributions of the complementary volume of the CEFR are undoubtedly important, they are specifically limited to audiovisual comprehension and online interaction, hence we end by proposing language activities that take into consideration all language skills and all channels of communication.
Nas margens da escrita académica
Authors: Costa Ana Luísa
Published: November 2022

Two case studies on academic writing aim at characterizing the writing profiles of students entering higher education through means other than the National Access Competition. The first case is the written task of an exam for students of professional and artistic courses applying for polytechnic institutes. The second one consists of the written diagnostic of a Workshop on Portuguese for Academic Purposes. Considering the Development Response as the aggregating textual genre, texts of the order of argument and explanation/exposition were analyzed. The study revealed globally higher results in case 1 (entrance test), difficulties across the whole set of texts, and specific problems in the group of students speaking varieties of Portuguese different from EP. Cross-cutting weaknesses were identified at the macrostructure level, such as the inclusion of counter-arguments and the elaboration of an adequate conclusion, as well as at the microstructure level, such as punctuation due to syntactic knowledge and limited use of contrastive and causal connectors. This characterization of students writing profiles at the entrance to higher education allows the development of intentional interventions in the writing practices of different scientific areas.
Valores e usos do diminutivo -inho no Português Europeu e no Português do Brasil
Authors: Rio-Torto Graça
Published: November 2022

This study aims to revisit the essential dimensions of the suffix -inho in Portuguese, either in the European or in the Brazilian Portuguese, and analyzes some of the descriptions that have been made of them, in order to clarify (i) the systemic value of -inho in the word-formation network of the Portuguese language, and (ii) the values of use that it admits, due to several variables, such as: the nature of the base to which it connects, the intonation and the elocutive’s intensity with which it is used, the illocutionary intentionality of the speaker, the evaluative value to be transmitted, the formal, informal, ironic and situational context and message in which it occurs.It is important to differentiate the systemic values of the suffix from the values that the derivative in which it occurs conveys, due to the characteristics of the text and the linguistic situation in which it is used. In a text produced in ironic or sarcastic register, the whole message is permeated by these values, but it cannot be affirmed that the systemic value of the suffix is that of irony or sarcasm, classes that do not configure any derivational paradigm of Portuguese.Thus, besides to provide a categorization of the semantic-pragmatic values associated with the use of this suffix and to reanalyze some myths that persist in some of its descriptions, the elaboration of this text has also a pedagogical intention: to provide PL2 learners with an overview of the values and uses of the diminutive suffix -inho in Portuguese, that allows them to effectively use the suffix in their interaction with native speakers of Portugal or of Brazi
Integrated Spillover Effect of Cross-Listed Stock Markets on the Indian Equity Market

Published: November 2022

The increased integration due to cross-listing leads to the volatility spillover effect on the domestic market posing from the cross-listed global indices viz., Nifty 50 from India, Luxx 100 from Luxembourg, NASDAQ from the US, and FTSE_Aim 100 from the UK. Johansen Co-integration test is applied to check the level of integration, which is further checked by multivariate granger causality showing the causality pattern among the indices. GARCH (1,1) model is applied to examine the volatility spillover effect on the Indian Stock Market. The findings suggest that the series are co-integrated with one vector ‘v,’ which is confirmed by the Trace and Max-Eigen Test. The Multivariate Granger Causality test confirms the bivariate causal pattern between India and US markets, implying the dual effect. In contrast, the Luxembourg market is relatively exogenous, which gives investors an opportunity for portfolio diversification. ARCH term is significant in the GARCH (1,1) model showing that the past innovation in the time series leads to the present fluctuation in the Indian stock market. Also, the results show a significant spillover effect from the US and UK markets. Thus, this will assist the investors that by concentrating on the movement of these markets, they can take specific actions regarding portfolio management.
Role of Women's Cooperative in Empowering Women: A Study in Jharkhand

Published: November 2022

The question of women empowerment consists of numerous nuances. Though the primary perspective continues to be the empowerment of the self, yet the process of self -actualization is largely dependent on a number of other factors including the complex interplay of societal forces and factors. The study of tribal women in the state of Jharkhand, India, provides incisive and rare insights to the process of women empowerment. Studied from the perspective of a women led cooperative society that sought to provide increased income to its members through poultry farming, the study provides a fascinating glimpse to the subsequent changes in the inter personal relationship and self-esteem among the women members..

Background

Several studies have explored the predictive performance of machine learning–based breast cancer risk prediction models and have shown controversial conclusions. Thus, the performance of the current machine learning–based breast cancer risk prediction models and their benefits and weakness need to be evaluated for the future development of feasible and efficient risk prediction models.

Objective

The aim of this review was to assess the performance and the clinical feasibility of the currently available machine learning–based breast cancer risk prediction models.

Methods

We searched for papers published until June 9, 2021, on machine learning–based breast cancer risk prediction models in PubMed, Embase, and Web of Science. Studies describing the development or validation models for predicting future breast cancer risk were included. The Prediction Model Risk of Bias Assessment Tool (PROBAST) was used to assess the risk of bias and the clinical applicability of the included studies. The pooled area under the curve (AUC) was calculated using the DerSimonian and Laird random-effects model.

Results

A total of 8 studies with 10 data sets were included. Neural network was the most common machine learning method for the development of breast cancer risk prediction models. The pooled AUC of the machine learning–based optimal risk prediction model reported in each study was 0.73 (95% CI 0.66-0.80; approximate 95% prediction interval 0.56-0.96), with a high level of heterogeneity between studies (Q=576.07, I2=98.44%; P<.001). The results of head-to-head comparison of the performance difference between the 2 types of models trained by the same data set showed that machine learning models had a slightly higher advantage than traditional risk factor–based models in predicting future breast cancer risk. The pooled AUC of the neural network–based risk prediction model was higher than that of the nonneural network–based optimal risk prediction model (0.71 vs 0.68, respectively). Subgroup analysis showed that the incorporation of imaging features in risk models resulted in a higher pooled AUC than the nonincorporation of imaging features in risk models (0.73 vs 0.61; Pheterogeneity=.001, respectively). The PROBAST analysis indicated that many machine learning models had high risk of bias and poorly reported calibration analysis.

Conclusions

Our review shows that the current machine learning–based breast cancer risk prediction models have some technical pitfalls and that their clinical feasibility and reliability are unsatisfactory.
