Determining factors of teachers’ readiness to teach economics using a spiral progression approach
Authors: Cebe Danilo , Suson Roberto
Published: September 2023

The Philippine K-12 curriculum embraces the spiral progression approach as a learning strategy that revisits and reinforces themes throughout a student's educational journey, gradually increasing their complexity. Despite the abundance of literature on spiral progression in education, there is limited research on teachers' readiness to implement this approach, specifically in the field of economics. This study aims to address this gap by evaluating teachers' readiness based on their profiles and knowledge of economics during the first and second grading periods. Through descriptive analysis, this paper provides insights into teachers' readiness and the necessity of utilizing the spiral progression approach to achieve the goal of producing globally competitive graduates. The study involved 29 social studies teachers selected through the "side judgment" purposive sampling technique, which was the most appropriate for this study's purpose. The findings indicate that teachers' readiness is positively influenced by factors such as educational attainment, specialization, teaching experience, mentoring received, and training attended. However, age and meetings attended do not directly affect teachers' readiness. These results contribute to both theoretical understanding and the practical application of teacher readiness in implementing the spiral progression approach. Moreover, this study sheds light on the readiness of teachers to use the spiral progression approach when teaching economics. The analysis provides valuable insights for both researchers and educators, facilitating a deeper understanding of teacher readiness and emphasizing the importance of implementing the spiral progression approach to produce globally competitive graduates.

The purpose of this study was to develop a mathematical model of the photoplethysmogram, which can be used to test methods that introduce the instantaneous phases of the modulating signals. The model must reproduce statistical and spectral characteristics of the real photoplethysmogram, and explicitly incorporate the instantaneous phases of the modulating signals, so they can be used as a reference during testing. Methods. Anacrotic and catacrotic phases of the photoplethysmogram pulse wave were modeled as a sum of two density distributions for the skew normal distribution. The modulating signals were introduced as harmonic functions taken from the experimental instantaneous phases of the VLF (0.015...0.04 Hz), LF (0.04...0.15 Hz) and HF (0.15...0.4 Hz) oscillations in the real photoplethysmogram. The spectral power in the VLF, LF, and HF frequency ranges was calculated to compare the model and experimental data. Results. The model qualitatively reproduces the shape of the experimental photoplethysmogram pulse wave and shows less than 1% error when simulating the spectral properties of the signal. Conclusion. The proposed mathematical model can be used to test the methods for introduction of the instantaneous phases of the modulating signals in photoplethysmogram time-series.

The purpose of this study is to detect the characteristic features of the oscillatory electrical activity of the brain in early postnatal development, depending on the gestational age of newborns. Methods. The study is based on automatic processing of clinical data from electroencephalography of newborns on the third day after birth. Behavioral characteristics assessed periods of sleep and wakefulness, without a precise division into stages of sleep and various states of wakefulness. The processing of multichannel electroencephalography signals was carried out on the basis of the method of modifying the continuous wavelet transform (CWT), which makes it possible to estimate the average characteristics of the number, duration and energy of oscillatory components (patterns) developing in different frequency ranges. Results. A paradoxical picture has been demonstrated describing the state of sleep and wakefulness in weakly preterm infants. For this group of children, the number and average energy of patterns detected in the frequency ranges from 1 to 20 Hz behave in a reflected way during sleep compared to children born at the usual time. At the same time, the average duration of oscillatory patterns remains unchanged. Conclusion. In the first days of a child’s life, it is possible to detect significant differences in the activity of the brain of newborns with slightly different gestational age during sleep/wake behavioral states. Quantitative estimates of the parameters of oscillatory CWT patterns are promising for use as the basis for systems for automatic processing of neonatal brain activity, additional to amplitude electroencephalography estimates. Such systems may be relevant for the search for early signs of anomalies in the development of the central nervous system.
Low 2D:4D is associated with delayed age at menarche among women of Sikkim, India
Authors: Mondal Nitish , Rai Rebaka
Published: September 2023

The index-finger and ring-finger ratio (2D:4D) is a potential biomarker that reflects prenatal hormonal exposure and thus has a long-term impact on reproductive health. The present study aims to determine the relationship between the 2D:4D (representing the prenatal hormonal environment, i.e., early androgen exposure) and early or delayed age at menarche among women in Sikkim, India. A total of one hundred nineteen Sherpa tribal women, ages 18–49, from the Soreng district of Sikkim, India, were included in the study using a stratified random sampling method. To calculate the 2D:4D ratio, the lengths of the index and ring fingers (2D and 4D) were measured using standard procedures. The category-wise mean comparison revealed that women with a more feminine 2D:4D ratio (in both left and right hand) had significantly earlier age at menarche (in years) compared to women with a more masculine 2D:4D ratio. The linear regression analysis revealed that the left 2D:4D was significantly related to menarche age. There is an association between the 2D:4D and menarche age, indicating a link between women’s reproduction patterns and the influence of the prenatal hormonal environment as an important factor in attaining an early or delayed menarcheal age.
On the Verge of Damnation and Buddhahood: Motherhood, Female Corporeality, and Koan Exegesis
Authors: Sanvido Marta
Published: September 2023

Buddhist scriptures depict the female body according to two contrasting models. On the one hand, female flesh is the epitome of defilement that hinders proper salvation. Yet, on the other hand, the gestational body is employed as a metaphor and a model to depict the highest spiritual perfection of the Buddhist clergy. By investigating these two seemingly incompatible approaches, this article shows how these contrasting models coexisted within the same doctrinal framework in early modern Sōtō Zen secret sources. In particular, it explores a Sōtō Zen secret document from the early modern period entitled Ise niji kirigami, which provides the doctrinal foundation for salvific rituals directed to women who died during parturition. The peculiarity of this document is the combination of conceptualizations typically associated with female pollution with a wide range of theorizations mainly derived from esoteric discourse on the kami, the Lotus Sūtra, and Zen koan interpretations. Therefore, through the investigation of the affinities with koan exegesis, Buddhist scriptures, and kami-related theories, this article aims to broaden our understanding of the tools used by early modern Zen monks to theorize the female body and contribute to the ongoing debate on the representation of the female spiritual and corporeal condition in Buddhist sources.

Published: September 2023

This paper is situated within territorial economics, with the noble aim of elucidating the intricate interplay between territorial human capital and the economic advancement of the esteemed Agadir Ida Outanane prefecture, particularly within the social innovation concept. It endeavors to navigate the nuances of theoretical intricacies and empirical analysis tools, all in a concerted effort to address the paramount inquiry: "To what extent can territorial human capital serve as a propelling force for the development of the Agadir Ida Outanane area, and how might social innovation contribute thereto?" In pursuit, we have adopted a methodological approach rooted in deductive reasoning and underpinned by a post-positivist paradigm. Through a judicious synthesis of theoretical constructs and observed realities, we have deftly formulated a hypothetical model that interweaves the concepts of territorial human capital, social innovation, and economic valorization of the territory. This model has been tested on a dataset comprising 180 operational cooperatives in the revered Agadir Ida Outanane area. The discerning findings of this inquiry concur with the existence of substantial and noteworthy contributions among the multifarious concepts under scrutiny.

The main aim of this study is to evaluate the effectiveness of the course designed by the author, which focuses on practical application, in improving students' pedagogical skills. Furthermore, the research aims to identify the challenges faced by teacher education institutions in this context and examine the mechanisms involved in improving pedagogical capabilities. The evaluation of students' instructional capacity is conducted through the utilization of both quantitative and qualitative methodologies. The Mann-Whitney U-test statistical test was used to confirm that the data conformed to the normal distribution law. The research encompassed a sample of 51 students from Zhetysu University, specifically named after I. Zhansugurov, located in Kazakhstan. The results showed that the conditions for supporting the pedagogical potential of students are not sufficiently created at the university. This demonstrated the necessity of the upcoming tasks, which included the introduction of the author's practice-oriented course and the development of pedagogical environments for the preparation of future educators to enhance their pedagogical potential. Finally, higher education policy experts in Kazakhstan might employ "practice-oriented courses" and pedagogical settings to improve the pedagogical expertise of future educators in pedagogical universities.

Published: September 2023

The paper aims to reconstruct the fluctuations of Dobrowolski Glacier, a tidewater glacier located in the inner position of the Admiralty Bay (King George Island, Antarctica), from the Little Ice Age (1400-1700) until the present. Measurements of the glacier’s area and length were based on multitemporal satellite imagery and submarine glacial landforms. The glacier surface area variations between the Little Ice Age and 2014 A.D were estimated. Morainic banks and paleoglacial reconstructions provided evidence of fluctuations in the surface area of the glacier between PIG and 2014 AD. Therefore, four stages of analysis were established: Stage I (Part I) (1400 to 1700), Stage I (Part II) (1700 until the mid-20th century), Stage II (mid-20th century until the 1980s), Stage III (1980 to 2000), and Stage IV (2000 to 2020). The climate during the Little Ice Age triggered the last major glacial advance, and their grounding line position was recorded by an external and prominent morainic bank. After the major glacial advance position of the grounding line, the ice-margin has undergone higher retreat rates (stage I) as response to the warming trend and the loss of anchoring point. The stage II (Unit B) is recorded by distal and discontinuous morainal ridges and glacial lineations formed in the context of an active ice flow at a deeper point in the fjord. During stage III (Unit C) glacial lineations and steep slopes occur, while landforms are less preserved, revealing a fast shrinkage phase. Stage IV is characterized by discontinuous morainic ridges (Unit D), when the glacier presents the highest annual glacial area loss.  Currently, the accelerated shrinkage may be linked to the loss of anchorage on seamounts (serving as pinning points) and increased warming. The U-shaped valley geometry has also influenced the glacier shrinkage processes and the redirection of glacial paleoflow during the last 300 years. The retreat rate to mid-20th century-2020 period is higher than Little Ice Age- mid-20th century period.
Effect of the alcoholic strength of unaged wine distillates on the final composition of Brandy de Jerez aged in Sherry Casks®
Authors: Butron Daniel , Valcárcel-Muñoz Manuel J. , García-Moreno M. Valme , Rodríguez-Dodero M. Carmen , Guillén-Sánchez Dominico A.
Published: September 2023

Brandy is a spirit obtained from distilled wine that has an alcohol content equal to or greater than 36 % ABV (Alcohol by Volume). It undergoes an ageing process in oak wood casks with a capacity of up to 1000 L for a minimum of six months. During this process, a series of physicochemical and sensory changes take place that confer the initial wine distillate with a series of improvements to its sensory profile. Such changes are mainly determined by the intrinsic characteristics of the wood and by those associated with the manufacturing process of the casks. The previous use of the casks, ageing time and the alcoholic strength of the wine distillate are also important factors, among others. The casks, which will have previously contained some type of Sherry wine (such as Fino, Amontillado, Oloroso and Pedro Ximénez), are known as Sherry Casks® and they must be used in the production of Brandy de Jerez. During the ageing of Brandy de Jerez, Sherry Casks® contribute to the final brandy via the compounds that are both inherent to the wood they are made of and from the wine that they initially contained and that were retained in the wood pores. The alcohol content of the wine distillate to be aged significantly affects not only the quality of the brandy, but also the financial cost of the process. This study aimed to determine the influence on brandy of the alcoholic strength of wine distillates aged in static ageing systems using Sherry Casks®. Specifically, we assessed the physicochemical composition and sensory profile of Brandy de Jerez made from wine distillates with three different alcoholic strengths (40 %, 55 % and 68 % ABV) and aged for 24 months. The Brandy de Jerez with lower alcoholic strengths (40 % - 55 % ABV) were found to contain a higher concentration of polyphenolic compounds deriving from the wood as well as from the constituents of the cask-seasoning Sherry wine. The brandies with higher alcoholic strengths exhibited a marked colour change, while the 40 % and 55 % ABV brandies were perceived to have the best sensory characteristics.
Novel Method for Ranking Generalized Fuzzy Numbers Based on Normalized Height Coefficient and Benefit and Cost Areas
Authors: Le Thi Hong Phuong , Chu Ta-Chung
Published: September 2023

To avoid loss of information and incorrect ranking, this paper proposes a method for ranking generalized fuzzy numbers, which guarantees both horizontal and vertical values are important parameters affecting the final ranking score. In this method, the normalized height coefficient is introduced to evaluate the influence of the height of fuzzy numbers on the final ranking score. The higher the normalized height coefficient of a fuzzy number is, the higher its ranking. The left area and the right area are presented to calculate the impact of vertical value on the final ranking score. The left area is considered the benefit area. The right area is considered the cost area. The fuzzy number is preferred if the benefit area is larger and the cost area is smaller. The proposed method can be employed to rank both normal and non-normal fuzzy numbers without normalization or height minimization. Numerical examples and comparison with other methods highlight the feasibility and robustness of the proposed method, which can overcome the shortcomings of some existing methods and can support decision-makers to select the best alternative.

Authors: Rovenski Vladimir
Published: September 2023

Weak contact metric structures on a smooth manifold, introduced by V. Rovenski and R. Wolak in 2022, have provided new insight into the theory of classical structures. In this paper, we define new structures of this kind (called weak nearly Sasakian and weak nearly cosymplectic and nearly K\"{a}hlerian structures) and study their geometry.

We introduce weak nearly K\"{a}hlerian manifolds (generalizing nearly K\"{a}hlerian manifolds) and characterize weak nearly Sasakian and weak nearly cosymplectic hypersurfaces in such Riemannian manifolds.

Optimal Cluster Scheduling of Active/Reactive Power for Distribution Network Considering Aggerated Flexibility of Heterogeneous Building-Integrated DERs
Authors: Fu Yu , Hao Shuqing , Zhang Junhao , Yu Liwen , Luo Yuxin , Zhang Kuan
Published: September 2023

This paper proposes an active-reactive power collaborative scheduling model with cluster division for the flexible distributed energy resources (DERs) of smart building system to resolve the high complexity of centralized optimal scheduling of massive dispersed DERs in the distribution network. Specifically, the optimization objective of each cluster is to minimize the operational cost, the power loss cost, and penalty cost for the flexibility deficiency, and the second-order cone-based branch flow method is utilized to convert the power flow equations into the linearized cone constraints, reducing the nonlinearity and heavy computation burden of the scheduling model. Customized virtual battery models for the building-integrated flexible DERs are developed to aggregate the power characteristics of flexible resources while quantifying their regulation capacities with time-shifting power and energy boundaries. Moreover, a cluster division algorithm considering the module degree index based on the electrical distance and flexible balance contribution index is formulated for cluster division to achieve the information exchange and energy interaction in the distribution network with high proportion of building-integrated flexible DERs. Comparative studies have demonstrated the superior performance of the proposed methodology on the economic merits and voltage regulation.

The aim of the study was to assess the adaptability of Polish Red cows to extensive housing and feeding conditions. The study was carried out using 22 cows together with their offspring, kept on a certified organic family farm, from 15 October 2017 – the start of the winter feeding season – to 30 October 2018 – the end of the pasture season. The animals were kept as beef suckler cows, which stayed in the pasture during the summer and were kept in buildings with permanent access to a large cattle run in winter. The following were determined in the study: changes in the cows’ weight and body condition, daily gains in calves, 210-day standardized body weight, and estimated milk yield of suckler cows. To evaluate the cows’ health, blood was collected from them twice and analysed for haematological and biochemical parameters. The results indicated that during the study period the Polish Red cows had adequate body condition, normal vital parameters, and a normal course and development of pregnancy despite the sparse winter diet. This definitively confirms the breed’s high capacity to adapt to an extensive system.

Published: September 2023

Pathogens, especially invasive species, have caused significant global ecological, economic, and social losses in forests. Plant disease research has traditionally focused on direct interactions between plants and pathogens in an appropriate environment. However, recent research indicates that the microbiome can interact with the plant host and pathogens to modulate plant resistance and/or pathogen pathogenicity, and thereby altering the outcome of plant-pathogen interactions. Thus, this presents new opportunities for studying the microbial management of forest diseases. Compared to parallel studies on human and crop microbiomes, research into the forest tree microbiome and its critical role in forest disease progression has lagged. The rapid development of microbiome sequencing and analysis technologies has resulted in the rapid accumulation of a large body of evidence regarding the association between forest microbiomes and diseases. These data will aid the development of innovative, effective, and environmentally sustainable microbial management of forest diseases. Herein, in this review, we summarize the most recent findings on the dynamic structure and composition of forest tree microbiomes in belowground and aboveground plant tissues (i.e., rhizosphere, endosphere, and phyllosphere), as well as their pleiotropic impact on manipulating plant immunity and pathogen pathogenicity, highlighting representative examples of Biological Control Agents used to modulate relevant tree microbiomes. Lastly, we discuss the potential application of forest tree microbiomes in disease control as well as their future prospects and challenges.

The microbiome, once considered peripheral, is emerging as a relevant player in the intricate web of factors contributing to cancer development and progression. These often overlooked microorganisms, in the context of urological malignancies, have been investigated primarily focusing on the gut microbiome, while exploration of urogenital microorganisms remains limited. In light of this, our systematic review delves into the complex role of these understudied actors in various neoplastic conditions, including prostate, bladder, kidney, penile, and testicular cancers. Our analysis found a total of 37 studies, with prostate cancer-12, bladder cancer-20, kidney cancer-4, penile/testicular cancer-1, which reveals distinct associations specific to each condition, hinting at potential therapeutic avenues and future biomarker discoveries. It becomes evident that further research is imperative to unravel the complexities of this domain and provide a more comprehensive understanding.

Does Increasing Public Service Expenditure Slow the Long-Term Economic Growth Rate?—Evidence from China
Authors: Xiao Weize
Published: September 2023

Economic downturns have increased in recent years, and the impact of COVID-19 has slowed economic growth. The market’s overall pessimism led to a contraction in the government’s fiscal revenue. The Chinese economy has always relied on government investments. Local governments’ productive investments have directly contributed to capital formation, which has promoted rapid economic growth. With the increase in expenditure pressure and the tightening of income caliber, will the continuous growth of the proportion of public service expenditure affect the established growth goals and hinder the efficiency of economic growth? This study explains this based on a general equilibrium model containing two types of government expenditure and uses China’s 2010–2019 provincial panel data for the empirical analysis. The results show that, in the current economic situation, increasing the proportion of public service expenditure is conducive to further economic growth.
Private Placement, Investor Sentiment, and Stock Price Anomaly
Authors: Liu Gengwang , Yang Yue , Mo Wanting , Gu Wentao , Wang Rihan
Published: September 2023

The private placement of A-shares gained momentum with the release of the Administrative Measures for Securities Issuance of Listed Companies in 2006. This led to enhanced research on the impact of private placement on stock prices. In 2012, the Chinese government relaxed the requirements for directed issuance of listed companies, resulting in a surge of directed issuance since then. This study uses a sample of listed companies that conducted private placements in the A-share market between 2013 and 2021, to analyze the impact of investor sentiment on stock price differences after private placements from the perspective of short and long-term excess returns. This study constructs the non-main investor sentiment of individual stocks using high-frequency tick data of individual stocks and explores the relationship between this stock price anomaly and investor sentiment using multiple regression analysis. The results show a positive short-term announcement effect of A-share private placements, with the excess return rate occurring mainly before the plan announcement date. The stock price difference from the plan announcement date to ten trading days thereafter has a significantly negative relationship with the excess return rate. Furthermore, investor sentiment in private placements may negatively affect long-term stock performance. This study suggests that this phenomenon is caused by higher investor sentiment pushing stock prices upward in the short term, causing them to deviate from fundamentals, creating mispricing, and then driving them back to fundamentals, with information disclosure. After controlling for the severity of information disclosure, the effect of investor sentiment on long-term stock price performance becomes insignificant.

Authors: Tang Dan , Wei Jiangying
Published: September 2023

Objective: An interpretability model of enterprise digital transformation that integrates XGBoost and Shapley additive explanations (SHAP) is proposed to accurately identify the important factors that affect the digital transformation of enterprises and their mode of action, improve the digital capabilities and levels of enterprises, and prevent the risks of digital transformation of enterprises. Method: The annual report information of listed companies from 2009 to 2021 is used as the research object. First, the digital transformation index is constructed using the text mining method. Second, an enterprise digital transformation prediction model based on XGBoost is constructed and compared it with other mainstream algorithms, such as linear regression and random forest, to find a comprehensive optimal model.

This paper focuses on latecomers in technology standards alliances, a topic that has received limited attention in academia. Although latecomers have disadvantages in terms of technology and market access, they possess a strong desire to catch up technologically. As a fundamental characteristic of an alliance, alliance routines serve as a source of innovation for members and a basic unit of analysis, providing a new perspective for understanding and researching the technological catch-up of latecomers. In this paper, a questionnaire survey is conducted among 83 latecomer enterprises in a technology standards alliance. The survey covers strategic emerging industries, such as new energy, new-generation information technology, new materials, and high-end manufacturing. Then, hierarchical regression is performed for hypothesis testing. The research shows that the three dimensions of alliance routines significantly promote the utilization of technological catch-up by latecomer enterprises. However, the impact on the exploration technological catch-up varies, where the action logic promotes exploration technological catch-up while implicit norms hinder exploratory innovation with an inverted U-shaped impact. The absorptive capacity strengthens the positive impact of the three alliance routines on the exploitative innovation of latecomer enterprises and strengthens the inverted U-shaped relationship between mutual consensus and their exploratory innovation. Nonetheless, it fails to play a significant regulatory role in action logic or in the relationship between implicit norms and exploratory innovation of latecomers.

In order to improve the universality and security of the data management of the Internet of Things and avoid the single point of failure problem in the traditional management architecture, this paper proposes a massive connection management architecture based on blockchain. The blockchain is reconstructed according to the hierarchical structure of blockchain technology, and with reference to the attribute-based access control mechanism, a data exchange model is designed using gossip mode and TLS networking mode to ensure the safe transmission of data. The peer computer network technology, data signature, and consensus mechanism are used to complete the design of the data exchange network layer and realize the design of the blockchain-based massive connection management architecture, so as to effectively avoid the single point of failure problem in the traditional management architecture and greatly reduce the burden of the management center. The access requests of massive devices in 5G application scenarios were simulated, and the results showed that the blockchain-based access control architecture designed in this article can quickly process received requests, with information leakage below 10%, improving the security and processing performance of data connections, achieving efficient processing and management of large-scale data, and providing reliable guarantees for the development of the Internet era.

Published: September 2023

A three-dimensional (3D) loading device based on a pneumatic 3-universal-prismatic-universal (UPU) parallel manipulator (three chains with UPU joint each) is designed to apply time-varying multi-dimensional loads to a target. First, according to the principle of vector superposition and Newton–Raphson method, the inverse and forward kinematics of the loading device are analyzed. Second, based on the screw theory, the static mapping between the dynamic platform and actuations is derived. Third, a second-order mathematical model is established for pneumatic 3-UPU parallel mechanism based on proportional flow valve and a metal seal pneumatic cylinder. A referential inaccurate model is provided for the control algorithm during modeling. Fourth, based on active disturbance rejection control (ADRC) technique, a 3D loading control algorithm is proposed and dynamic loading control is realized. Experimental results show that the ADRC algorithm has good robustness against disturbances, the steady-state control accuracy is less than 2 N, and the mean square error in dynamic tracking (sinusoidal tracking at 0.2 Hz) is less than 10.5 N.

Published: September 2023

The rapid implementation of multi-task decoupling in restricted flight areas for unmanned aerial vehicle swarms is crucial to ensure swarm effectiveness. This study introduces a task-switching mechanism in the bio-inspired rule-based (Bio-RB) decision-making algorithm and establishes a mapping relationship from behavioral rules to task modes. A complete decision model is constructed for the cooperative search and package delivery tasks. To further improve the search efficiency of swarms in restricted areas, a boundary-handling strategy based on the combination of path prediction and virtual agents is proposed. The overall scheme is termed the task-driven rule-based (Task-RB) decision-making algorithm. The proposed Task-RB method is evaluated under full-flow simulation. Numerical experiments demonstrate the superior performance of the proposed Task-RB method against the Bio-RB method under different instances.
