Published: August 2023

Introduction: The complete blood count parameters and its combinations, such as neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and mean platelet volume (MPV), are inflammatory markers. In this study, we aimed to demonstrate the possible role of complete blood count parameters (NLR, PLR, and MPV) in predicting preterm birth.

Material and Methods: The complete blood count parameters in the first and third trimesters were recorded, as well as the corresponding NLR, PLR, and MPV. The study population was categorized as preterm (n = 94) and term births (n = 953). The preterm birth group was further divided into early preterm (n = 11) and late preterm birth (n = 83) groups. The inflammatory markers were compared between the study groups for the first and third trimesters separately. The alterations between the first and third trimester values were also compared.

Results: The first trimester values were similar across the study groups. Moreover, the MPV difference between the first and third trimesters was significantly lower in the preterm group than in the term group (0.0  1.1 vs. 0.2  1.1, p = 0.038). Furthermore, NLR values were higher in the early preterm subgroup than in the late preterm and term groups for the first and third trimesters (first trimester; 4.0  1.2 vs. 3.1  2.0 and 3.1  1.3, p = 0.005; third trimester; 5.3  1.2 vs. 4.0  1.5 and 4.4  2.9, p = 0.013).

Conclusion: NLR and MPV predict preterm births in the first trimester and before birth. This enables physicians to take some precautions in preventing preterm delivery.

Published: August 2023

Employers are increasingly expressing concern that the majority of recent graduates lack professional skills. In addition, it is unknown whether students pursuing accounting degrees in professionally accredited institutions are more financially savvy than those in non-accredited institutions. 1582 undergraduate accounting students at the University of KwaZulu-Natal (UKZN), Mangosuthu University of Technology (MUT), and Durban University of Technology (DUT) were surveyed using self-administered questionnaires. The data was analysed using Statistical Package for the Social Sciences version 25 (SPSS 25). The results indicated that the majority of respondents were female.  72.6 percent of respondents are influenced by South African Institute of Charted Accountants (SAICA) accreditation, whereas 95.2 percent of respondents with outstanding professional skills are influenced by non-SAICA accreditation. The study's findings disprove previous claims that accreditation has no bearing on students' abilities. Finally, the investigation contributes South Africa-relevant knowledge..
The Effects of Africa's Infrastructure Crisis and its Root Causes
Authors: THUSI Xolani , MLAMBO Victor H
Published: August 2023

The development and expansion of any continent's economy is mostly dependent on the availability of world-class infrastructure capable of attracting international investors. The development and expansion of Africa's infrastructure is imperative; hence this will improve the African economy. The development and expansion of infrastructure improves the economy, resulting in many economic prospects for the inhabitants of any continent. However, in Africa, infrastructure development, investment, and preservation are among the lowest in the world. Infrastructure development will not only attract foreign investment and business, but it will also enhance trade between countries within the region. Trade between countries within the region is also heavily impacted by poor infrastructure investment in the continent, this puts much limit economic prospects within the region. This is a major concern; thus, Africa has several deficiencies in transport, telecommunications, water, health, and education infrastructures, all of which are crucial for Africa development. This is one of the main reasons why Africa has the highest levels of unemployment, poverty, food insecurity, migration, and poor education and health care systems. The author contends that investments and development in the African regional infrastructure are relatively low. This is a major barrier to regional economic development since the development of the region's economy relies on the development of infrastructure. This is unfortunate; hence, the region economy already lacks capabilities to provide the people with economic opportunities.  A qualitative method was used to investigate what is preventing infrastructure development in Africa and what this means for Africa as a developing continent.

Continuidades y rupturas en la historia chilena: otra hipótesis sobre la crisis chilena de 1973
Authors: Véliz Claudio
Published: August 2023

Muchas de las descripciones e interpretaciones de la crisis chilena de 1973 han dado demasiada importancia a los factores extremos y relativamente poca a los asuntos internos. Las grandes transformaciones que propiciaba el programa de gobierno de Salvador Allende —apertura hacia los países comunistas, nacionalización de la gran minería del cobre, reforma agraria— no constituían en sí mismas rupturas con la tradición chilena capaces de precipitar una crisis como la de 1973. Hubo, en cambio, otros elementos, especialmente de tipo económico, que sí implicaron una ruptura y que fueron los que hicieron imposible que Allende terminara legalmente su mandato constitucional. Este artículo se ocupa de los factores de ruptura de carácter no económico y explora tres de ellos: el sistema de cuotas políticas al interior del gobierno de la Unidad Popular, la tolerancia del gobierno ante el desarrollo de organizaciones revolucionarias paramilitares, y el estilo de gobierno y de vida personal que adoptó Allende y que lo distanciaron de la imagen de sobriedad y respetabilidad que siempre en Chile ha rodeado a la presidencia. A la luz de estos factores, el autor investiga las causas del fracaso de las conversaciones entre Allende y la Democracia Cristiana, que comenzaron a fines de julio de 1973.

The Star Formation Across Cosmic Time (SFACT) Survey. I. Survey Description and Early Results from a New Narrowband Emission-line Galaxy Survey
Authors: Salzer John J. , Carr David J. , Sieben Jennifer , Brunker Samantha W. , Hirschauer Alec S.
Published: August 2023

We introduce the Star Formation Across Cosmic Time (SFACT) survey. SFACT is a new narrowband survey for emission-line galaxies (ELGs) and QSOs being carried out using the wide-field imager on the WIYN 3.5 m telescope. Because of the superior depth and excellent image quality afforded by WIYN, we routinely detect ELGs to r = 25.0. Our survey observations are made using three custom narrowband filters centered on 6590 Å, 6950 Å, and 7460 Å. Due to the sensitivity of the survey, we are able to simultaneously detect sources via a number of different emission lines over a wide range of redshifts. The principal lines detected in SFACT are Hα (redshifts up to 0.144), [O iii]λ5007 (redshifts up to 0.500), and [O ii]λ3727 (redshifts up to 1.015). In this paper, we detail the properties of the survey as well as present initial results obtained by analyzing our three pilot-study fields. These fields have yielded a total of 533 ELG candidates in an area of 1.50 deg2 (surface density of 355 ELGs deg−2). Follow-up spectra for a subset of the ELG candidates are also presented. One of the key attributes of the SFACT survey is that the ELGs are detected in discrete redshift windows that will allow us to robustly quantify the properties of the star-forming and active galactic nucleus populations as a function of redshift to z = 1 and beyond. The planned acquisition of additional narrowband filters will allow us to expand our survey to substantially higher redshifts.
Iron-peak Element Abundances in Warm Very Metal-poor Stars

Published: August 2023

We have derived new detailed abundances of Mg, Ca, and the Fe-group elements Sc through Zn (Z = 21−30) for 37 main-sequence turnoff very metal-poor stars ([Fe/H] ≲−2.1). We analyzed Keck HIRES optical and near-UV high signal-to-noise spectra originally gathered for a Be abundance survey. Using typically ∼400 Fe-group lines with accurate laboratory transition probabilities for each star, we have determined accurate LTE metallicities and abundance ratios for neutral and ionized species of the 10 Fe-group elements as well as α elements Mg and Ca. We find good neutral/ion abundance agreement for the six elements that have detectable transitions of both species in our stars in the 3100–5800 Å range. Earlier reports of correlated Sc−Ti−V relative overabundances are confirmed, and appear to slowly increase with decreasing metallicity. To this element trio we add Zn; it also appears to be increasingly overabundant in the lowest-metallicity regimes. Co appears to mimic the behavior of Zn, but issues surrounding its abundance reliability cloud its interpretation.

We present a sample of four emission-line galaxies at z = 6.11–6.35 that were serendipitously discovered using the commissioning data for the James Webb Space Telescope (JWST)/NIRCam wide-field slitless spectroscopy mode. One of them (at z = 6.11) has been reported previously, while the others are new discoveries. These sources are selected by the secure detections of both [O iii] λ5007 and Hα lines with other fainter lines, which were tentatively detected in some cases (e.g., [O ii] λ3727, [O iii] λ4959). In the [O iii]/Hβ–[N ii]/Hα Baldwin–Phillips–Terlevich diagram, these galaxies occupy the same parameter space as that of z ∼ 2 star-forming galaxies, indicating that they have been enriched rapidly to subsolar metallicities (∼0.4 Z
⊙), similar to galaxies with comparable stellar masses at much lower redshifts. The detection of strong Hα lines suggests a higher ionizing photon production efficiency within galaxies in the early universe. We find brightening of the [O iii] λ5007 line-luminosity function (LF) from z = 3 to 6, and weak or no redshift evolution of the Hα line LF from z = 2 to 6. Both LFs are underpredicted at z ∼ 6 by a factor of ∼10 in certain cosmological simulations. This further indicates a global Lyα photon escape fraction of 7%–10% at z ∼ 6, which is slightly lower than previous estimates through the comparison of the UV-derived star formation rate density and Lyα luminosity density. Our sample recovers

Cosmological Constraints from the BOSS DR12 Void Size Function
Authors: Contarini Sofia , Pisani Alice , Hamaus Nico , Marulli Federico , Moscardini Lauro , Baldi Marco
Published: August 2023

We present the first cosmological constraints derived from the analysis of the void size function. This work relies on the final Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 12 (DR12) data set, a large spectroscopic galaxy catalog, ideal for the identification of cosmic voids. We extract a sample of voids from the distribution of galaxies, and we apply a cleaning procedure aimed at reaching high levels of purity and completeness. We model the void size function by means of an extension of the popular volume-conserving model, based on two additional nuisance parameters. Relying on mock catalogs specifically designed to reproduce the BOSS DR12 galaxy sample, we calibrate the extended size function model parameters and validate the methodology. We then apply a Bayesian analysis to constrain the Lambda cold dark matter (ΛCDM) model and one of its simplest extensions, featuring a constant dark energy equation of state parameter, w. Following a conservative approach, we put constraints on the total matter density parameter and the amplitude of density fluctuations, finding Ωm = 0.29 ± 0.06 and

. Testing the alternative scenario, we derive w = −1.1 ± 0.2, in agreement with the ΛCDM model. These results are independent and complementary to those derived from standard cosmological probes, opening up new ways to identify the origin of potential tensions in the current cosmological paradigm.

to be 0.108 dex and 0.147 dex for quiescent and star-forming galaxies, respectively. Finally, we inspect the residuals as a function of SPS parameters (dust, age, metallicity, and star formation rate) and spectral indices (Hα, Hδ, and D

n
4000). For quiescent galaxies, ∼65% of the scatter can be explained by the uncertainty in SPS parameters, with dust and age being the largest sources of uncertainty. For star-forming galaxies, while age and metallicity are the leading factors, SPS parameters account for only ∼13% of the scatter. These results leave us with remaining unmodelled scatters of 0.055 dex and 0.122 dex for quiescent and star-forming galaxies, respectively. This can be interpreted as a conservative limit on the precision in M

A Negative Long Lag from the Optical to the UV Continuum in Fairall 9
Authors: Yao Philippe Z. , Secunda Amy , Jiang 姜 Yan-Fei 燕飞 , Greene Jenny E. , Villar Ashley
Published: August 2023

We report the detection of a long-timescale negative lag, where the blue bands lag the red bands, in the nearby Seyfert 1 galaxy Fairall 9, with two independent methods. Active Galactic Nuclei (AGNs) light curves show variability over a wide range of timescales. By measuring time lags between different wavelengths, the otherwise inaccessible structure and kinematics of the accretion disk can be studied. One common approach, reverberation mapping, quantifies the continuum and line lags moving outward through the disk at the light-travel time, revealing the size and temperature profile of the disk. Inspired by numerical simulations, we expect longer lags to exist in AGN light curves that travel inward on longer timescales, tracing the accretion process itself. By analyzing AGN light curves in both temporal and frequency space, we report the detection of long-timescale lags (∼−70 days) in Fairall 9 that propagate in the opposite direction to the reverberation lag. The short continuum lag (<10 days) is also detected and is consistent with reverberation lags reported in the literature. When fitting the longer lag as a function of frequency with a model motivated by the thin disk model, we find that the disk scale height likely increases outward in the disk. This detection raises the exciting prospect of mapping accretion disk structures across a wide range of AGN parameters.
A Systematic Study of the Connection Between White Dwarf Period Spectra and Model Structure
Authors: Bischoff-Kim Agnès
Published: August 2023

To date, pulsational variability has been measured for nearly 70 pulsating helium-atmosphere white dwarfs (DBVs) and 500 pulsating hydrogen-atmosphere white dwarfs (DAVs), with only a fraction of these having been the subject of asteroseismic analysis. One way to approach white dwarf asteroseismology is forward modeling, where one assumes an interior structure and calculates the model’s periods. Many such models are calculated, in the search for the one that best matches the observed period spectrum. It is not computationally manageable, nor necessary, to vary every possible parameter for every object. We engage in a systematic study, based on a sample of 14 hydrogen-atmosphere white dwarfs, chosen to be representative of the types of pulsation spectra we encounter in white dwarf asteroseismology. These white dwarfs are modeled with carbon and oxygen cores. Our goal is to draw a connection between the period spectra and what parameters to which they are most sensitive. We find that the presence of longer-period modes generally muddies the mass and effective temperature determinations, unless continuous sequences of ℓ = 1 and ℓ = 2 modes are present. All period spectra are sensitive to the structure in the helium and hydrogen envelopes and most to at least some features of the oxygen abundance profile. Such sensitivity can be achieved either by the presence of specific low-radial-overtone modes, or by the presence of longer-period modes. Convective efficiency only matters when fitting periods greater than 800 s. The results of this study can be used to inform parameter selection and pave the way to pipeline asteroseismic fitting of white dwarfs.
Event Rate of Strongly Lensed Gravitational Waves of Stellar Binary Black Hole Mergers Produced by Dynamical Interactions
Authors: Chen Zhiwei
Published: August 2023

Gravitational waves emitted from stellar binary black hole (sBBH) mergers can be gravitationally lensed by intervening galaxies and detected by future ground-based detectors. A great amount of effort has been put into the estimation of the detection rate of lensed sBBH originating from the evolution of massive binary stars (EMBS channel). However, sBBHs produced by the dynamical interaction in dense clusters (dynamical channel) may also be dominant in our universe and their intrinsic distribution of physical properties can be significantly different from those produced by massive stars, especially mass and redshift distribution. In this paper, we investigate the event rate of lensed sBBHs produced via the dynamical channel by Monte Carlo simulations and the number is

Systematic Research of Low-redshift Optically Selected SDSS Type 2 AGNs but with Apparent Long-term Optical Variabilities from Catalina Sky Survey. I. Data Sample and Basic Results
Authors: Zhang XueGuang
Published: August 2023

The main objective of this article, the first in a dedicated series, is to report basic results on systematic research of low-redshift optically selected SDSS Type 2 active galactic nuclei (AGNs) but with apparent optical variabilities. For all the pipeline-classified Type 2 AGNs in SDSS DR16 with z < 0.3 and signal-to-noise ratio > 10, long-term optical V-band light curves are collected from the Catalina Sky Survey. Through all light curves described by a damped random walk process with process parameters of σ/(mag/days0.5) and τ/days, 156 Type 2 AGNs have apparent variabilities with process parameters at least 3 times larger than corresponding uncertainties and with ln(σ/(mag/days0.5)) > −4, indicating central AGN activity regions directly in the line of sight, leading the 156 Type 2 AGNs as misclassified Type 2 AGNs. Furthermore, based on spectroscopic emission features around Hα, 31 out of the 156 AGNs have broad Hα, indicating the 31 Type 2 AGNs are actually Type 1.8 and/or 1.9 AGNs. Meanwhile, 14 out of the 156 AGNs have multiepoch SDSS spectra. After checking multiepoch spectra of the 14 objects, no clues for appearance and/or disappearance of broad lines indicates true Type 2 AGNs rather than changing-look AGNs are preferred in the collected Type 2 AGNs with long-term variabilities. Moreover, a small sample of Type 2 AGNs have long-term variabilities with features roughly described by theoretical tidal disruption events (TDEs) expected t
−5/3, indicating probable central TDEs as further and strong evidence to support true Type 2 AGNs.

Published: August 2023

The Squirrels of South Asia (SOSA) database compiles comprehensive distribution and occurrence information on all squirrel species that occur in this region (34 species). These 34 squirrel species, including tree, flying and ground squirrels, represent 14% of global sciurid diversity. The database collates curated data from various sources such as museums, literature, primary fieldwork, citizen science, and social media platforms and covers the entire distributional ranges of the target species, including countries in Central Asia and Southeast Asia when required. The SOSA database enhances our understanding of squirrel distribution, population dynamics, and their conservation needs in South Asia by consolidating information. It aims to be a valuable resource for researchers, conservationists, and wildlife enthusiasts.

As of March 2023, the database comprises over 40,000 records of 34 species in over 30 countries globally. Spending an average of 334 hours on each species, more than 20 data collectors put in over 10,000 hours to gather, curate, and build this database. The database has resulted in novel records of species occurrence in regions and countries that are poorly represented in currently available global data repositories. The current vesrion which has been made public via GBIF comprises of 1187 records of all 34 species across multiple sources. This is a subset of the SOSA database.
SPARSE 1.0: a template for databases of species inventories, with an open example of Czech birds
Authors: Tschernosterová Kateřina , Trávníčková Eva , Grattarola Florencia , Rosse Clara , Keil Petr
Published: August 2023

Here we introduce SPARSE (acronym for "SPecies AcRoss ScalEs"), a simple and portable template for databases that can store data on species composition derived from ecological inventories, surveys, and checklists, with emphasis on metadata describing sampling effort and methods. Sparse can accommodate resurveys and time series, and data from different spatial scales, as well as complex sampling designs. SPARSE focuses on inventories that report multiple species for a given site, together with sampling methods and effort, which can be used in statistical models of true probability of occurrence of species. SPARSE is spatially explicit, and can accommodate nested spatial structures from multiple spatial scales, including sampling designs where multiple sites within a larger area have been surveyed, and the larger area can again be nested in an even larger region. Each site in SPARSE is represented either by a point, line (for transects), or polygon, stored in an ESRI shapefile. SPARSE implements a new combination our own field definitions with Darwin Core biodiversity data standard and its Humboldt core extension. The use of Humboldt core also makes SPARSE suitable for biodiversity data with temporal replication.

We provide an example use of the SPARSE framework by digitizing data on birds from the Czech Republic, from 348 sites and 524 sampling events, with 15,969 unique species-per-event observations of presence, abundance, or population density. To facilitate use without the need for a high-level database expertise, the Czech bird example is implemented as MS Access .accdb file, but can be ported to other database engines. The example of Czech birds complements other bird datasets from the Czech Republic, specifically the four gridded national atlases and the breeding bird survey which cover a similar temporal extent, but different locations and spatial scales.

Due to its complex geological history and the emergence of various biogeographic regions, the Philippines boasts an extraordinary array of flora and fauna. This unique combination has contributed to the country’s exceptional density of terrestrial species, positioning it among the highest in the world. Mindanao, in the southern part of the Philippines, is the second largest group of islands and supports high biodiversity of unique and threatened species of flora and fauna. However, consolidated biodiversity records and information remain unavailable for the region. Filling these significant gaps would advance understanding biodiversity patterns in Mindanao across time and space. The Mindanao Open Biodiversity Information (MOBIOS+) database aims to consolidate 21st-century biodiversity data and establish an open-access database. The database we present here is the first of its kind and currently the most comprehensive attempt to establish the largest consolidated database for Mindanao biodiversity. With its vast collection of biodiversity data, this database will prove to be a valuable resource for advancing biodiversity research and analysis. It will facilitate the identification of species and areas that require immediate conservation prioritization and action, addressing the urgent challenges posed by our rapidly changing planet.

The MOBIOS+ database is the first attempt to create a massive FAIR database aiming to collate biodiversity records in the Mindanao faunal region, South of the Philippines. The database currently includes 12,814 georeferenced species occurrences from 1,925 unique species or taxa from 10 animal classes from the Mindanao faunal region's terrestrial and freshwater bodies. We made all georeferenced species occurrences available in the Global Biodiversity Information Facility (GBIF) platform.

This study aims to investigate the anti-hyperlipidaemic effect of ethanolic leaf extract of Equisetum ramosissimum. 2,2-Diphenyl-1- picrylhydrazyl assay for antioxidants, Folin-Ciocalteu, AlCl3, and UHPLC-MS/MS analysis, focusing on phenols and flavonoid content were performed. Anti-hyperlipidemic effect of the extract on lipid profile and body weight was evaluated alone or in combination with Atorvastatin in rats. The extract was shown to contain phenols (0.032±0.001 µg/g, equivalent to gallic acid), flavonoids (0.044±0.003 mg/g, equivalent to quercetin), and antioxidant IC50 value of (1000.00±0.78 µg/mL). UHPLC-MS/MS analysis revealed the presence of 8 different phenols and flavonoids. An in vivo study on healthy standard diet-fed animals and an induced hyperlipidaemic model showed a significant (P < 0.05) reducing effect of the extract alone and in combination with Atorvastatin on serum lipid profile. These findings revealed the potential advantages of the extract alone and in combination with statins for preventing or treating hyperlipidaemia, but need to be further explored.

Published: August 2023

In this study, the Laena species from northern Sichuan Province were reviewed using a combination of molecular and morphological datasets. Three molecular methods for species delimitation were firstly used in the genus Laena to explore species boundaries. The results show that the number of morphospecies and putative species using Automatic Barcode Gap Discovery (ABGD) is consistent. Based on the results, two new species are described and illustrated: Laena mounigouicasp. nov. and Laena dentithoraxasp. nov. New materials and distribution of 10 Laena species are also provided in this study. This work also provides valuable molecular data for species identification and phylogenetic analyses of the genus Laena and subfamily Lagriinae.
Adverse Childhood Experiences and Depression: The Mediating Role of Resilience and Emotional Regulation
Authors: Elrefaay Shaimaa Mosad Mohamed , Elyzal Ayat Saif
Published: August 2023

The current study examined the mediating roles of resilience and emotional regulation in the association between childhood trauma and depressive symptoms among individuals who experienced adverse childhood experiences (ACEs). Data from 200 women aged 17 to 77 years who were psychiatric outpatients were collected using self-reported questionnaires assessing child adversity, depressive symptoms, resilience, and emotional regulation. A positive correlation was found between a subscale of the ACE-IQ and depression. Childhood trauma was associated with higher risk of depressive symptoms among participants with lower resilience (an association that was partly explained by resilience level [mediation]). Emotional regulation was not a significant mediator in the childhood trauma–depression association. Our findings indicate that resilience is a key mediator between childhood trauma and depression. Individuals who experienced childhood trauma may benefit from evidence-based interventions focused on strengthening resilience and improving coping strategies. [

Control and adaptive modified function projective synchronization of different hyperchaotic dynamical systems
Authors: El-Dessoky M. M. , Almohammadi Nehad , Alzahrani Ebraheem
Published: August 2023

In this work, we consider an adaptive control method, which is simpler and generalized to obtain some conditions on the parameters for hyperchaotic models determined by using a Lyapunov direct method. Further, an adaptive controller for synchronization is designed by using Lyapunov functions by which the deriving system and the response system can realize adaptive modified function projective synchronization up to scaling matrix. Numerical simulation of each system is discussed in detail with graphical results. The graphical results are presented in detail in order to validate the theoretical results. These results in this article generalize and improve the corresponding results of the recent works.
The impact of population agglomeration on ecological resilience: Evidence from China
Authors: Zhu Qingsheng , Xie Changwen , Liu Jia-Bao
Published: August 2023

Due to climate change and human activities, ecological and environmental issues have become increasingly prominent and it is crucial to deeply study the coordinated development between human activities and the ecological environment. Combining panel data from 31 provinces in China spanning from 2011 to 2020, we employed a fixed-effects model, a threshold regression model, and a spatial Durbin model to empirically examine the intricate impacts of population agglomeration on ecological resilience. Our findings indicate that population agglomeration can have an impact on ecological resilience and this impact depends on the combined effects of agglomeration and crowding effects. Also, the impact of population agglomeration on ecological resilience exhibits typical dual-threshold traits due to differences in population size. Furthermore, population agglomeration not only directly impacts the ecological resilience of the local area, but also indirectly affects the ecological resilience of surrounding areas. In conclusion, we have found that population agglomeration does not absolutely impede the development of ecological resilience. On the contrary, to a certain extent, reasonable population agglomeration can even facilitate the progress of ecological resilience.
Investigating the effect of university enterprise collaboration on individual innovation in underdeveloped regions
Authors: Liu Hui , Sukpasjaroen Khunanan , Zhai Xuesong
Published: August 2023

The innovation capability index of underdeveloped regions lags far behind that of the eastern coastal areas. This imbalance in innovation capability poses a critical challenge for underdeveloped regions in implementing its innovation-driven development strategy and economic transformation. Individual collaborative innovation ability is an essential skill that allows individuals to transform knowledge and resources into economic value. Presently, research on individual collaborative innovation capability focuses only on the external environment, cooperation mode and benefit allocation. This approach fails to reveal how organizational factors affect individual collaborative innovation capability, and there is a lack of research on underdeveloped regions. Collaborative innovation theory proposes that deep cooperation between industries or institutions through acquiring resources and knowledge can have a positive impact on other environments. Improving individual collaborative innovation capabilities must be achieved through the integration of heterogeneous innovation resources owned by the two core innovation entities, to achieve full integration of innovation elements. Therefore, collaborative innovation theory can effectively address this problem. This article adopts a quantitative research method. A sample of 911 teachers was selected from thirty vocational colleges in Inner Mongolia. The data were analyzed using the Hierarchical Linear Modeling (HLM) model and the proposed relationship was validated. The research findings indicate that cognitive, social and geographical proximity have significant positive effects on collaborative behavior. Collaborative behavior has a significant positive impact on individual collaborative innovation ability. Collaborative behavior plays a mediating role between multidimensional proximity and individual collaborative innovation ability. This study will add information on the collaborative innovation theory, help to understand the formation and impact mechanism of cooperative relationships in school-enterprise cooperation in underdeveloped regions, and thus promote the development of STEM education in underdeveloped areas.

Although it was first developed and studied in the late 1970s and early 1977s, the Data Encryption Standard (DES) algorithm has grown in popularity. There are two causes for this occurrence. First, the DES algorithm's complex mathematical structure allows it to serve as the theoretical foundation for a wide variety of applications. Second, the encryption technique works quite well in practice for a variety of applications when implemented correctly. In this paper, we undertake a thorough and practical review of the theoretical aspects of this sort of encryption algorithm and demonstrate how they have been implemented by executing multiple encryption configurations.

Published: August 2023

This paper presents a conceptual framework that combines technology-based instruction and mathematical modeling in a STEAM-oriented approach to enhance the English language acquisition of Malaysian students. The proposed framework consists of a six-month English as a Foreign Language program that integrates technology and mathematical simulation in a STEAM-oriented methodology. The exercises are designed to enhance linguistic competence, with a focus on improving listening, speaking, reading, and writing skills. The framework aims to foster a positive learning environment that encourages self-determination and promotes sociocultural interaction. The integration of technology-enabled instruction and mathematical modeling offers a viable strategy for enhancing the language competency of non-native English speakers. However, further research and empirical analysis are necessary to evaluate the impact of this framework on academic performance. Despite this limitation, the proposed framework offers a promising approach to address the challenges faced by less proficient Malaysian students in acquiring English language skills. In conclusion, this paper presents a conceptual framework that integrates technology-based instruction and mathematical modeling in a STEAM-oriented approach to enhance the English language acquisition of less proficient Malaysian students. The framework is grounded in sociocultural and self-determination theoretical perspectives and aims to create a positive learning environment that promotes linguistic competence.

Identifying and classifying text extracted from social networks, following the traditional method, is very complex. In recent years, computer science has advanced exponentially, helping significantly to identify and classify text extracted from social networks, specifically Twitter. This work aims to identify, classify and analyze tweets related to real natural disasters through tweets with the hashtag #NaturalDisasters, using Machine learning (ML) algorithms, such as Bernoulli Naive Bayes (BNB), Multinomial Naive Bayes (MNB), Logistic Regression (LR), K-Nearest Neighbors (KNN), Decision Tree (DT), Random Forest (RF). First, tweets related to natural disasters were identified, creating a dataset of 122k geolocated tweets for training. Secondly, the data-cleaning process was carried out by applying stemming and lemmatization techniques. Third, exploratory data analysis (EDA) was performed to gain an initial understanding of the data. Fourth, the training and testing process of the BNB, MNB, L, KNN, DT, and RF models was initiated, using tools and libraries for this type of task. The results of the trained models demonstrated optimal performance: BNB, MNB, and LR models achieved a performance rate of 87% accuracy; and KNN, DT, and RF models achieved performances of 82%, 75%, and 86%, respectively. However, the BNB, MNB, and LR models performed better with respect to performance on their respective metrics, such as processing time, test accuracy, precision, and F1 score. Demonstrating, for this context and with the trained dataset that they are the best in terms of text classifiers.
