A novel deep anomaly detection approach for intrusion detection in futurisitic network

<span lang="EN-US">In an era where networks are increasingly heterogeneous and multi-domain, establishing robust security models to protect data and network infrastructure is becoming ever more complex. Traditional intrusion detection systems (IDS) often struggle with novel or variant attacks that fall outside predefined rule sets, resulting in significant detection challenges. This paper proposes a methodologically refined approach leveraging data-driven insights and statistically robust feature selection to enhance the training dataset. The study presents a long short-term memory-autoencoder (LSTM-AE) based learning model designed for multi-class anomaly detection. The model's novelty lies in its application of distance metrics to define distinct thresholds for varied attack classifications, a strategy that significantly amplifies detection precision. Experimental results validate the superior performance of the proposed system, achieving 94.82% accuracy rate, outperforming similar existing works. The study also proactively addresses common issues of class imbalance and skewed data representation in benchmark datasets by strategically training the model on normal traffic, enhancing its capability to generalize and identify anomalies effectively.</span>

"All of us are capable, and all of us can be scientists." The impact of Scientist Spotlight assignments with undergraduates in physiology courses.

To advance ongoing efforts to diversify the healthcare field and promote inclusion in physiology education, the present study investigates the potential for an evidence-based intervention, Scientist Spotlight assignments, to highlight counterstereotypical representations of scientists in the context of majors and nonmajors physiology courses. Undergraduate students at an emerging Hispanic serving R1 institution completed six Scientist Spotlights assignments in their physiology courses. We conducted semistructured interviews and disseminated an established pre- and postsurvey protocol at the beginning and end of the courses. Our findings from interviews with 31 students from a range of marginalized backgrounds revealed that 1) the biographical information about counterstereotypical scientists deeply resonated with students by humanizing science, 2) the instructor's implementation of the assignments made a meaningful difference in their feelings of inclusion, and 3) the assignments supported students' beliefs about their content learning and understanding of physiological concepts. The results from the survey showed that regardless of being in a major (n = 159) or nonmajor (n = 117) course, students from a range of demographic groups can and do significantly shift in their relatability to and descriptions of scientists. We highlight implications for inclusive curricula like Scientist Spotlights for addressing the issue of representation in physiology textbooks, curriculum, and healthcare fields at large.NEW & NOTEWORTHY Scientist Spotlights significantly enhance undergraduate students' feelings of inclusion and learning in undergraduate physiology courses at an emerging Hispanic-serving institution. By engaging with assignments featuring counterstereotypical scientists, students in both majors and nonmajors physiology courses shifted in their relatability to and descriptions of scientists. These results suggest that an inclusive curriculum, combined with supportive instructor practices, can positively impact student success and representation in physiology education.

CRBPSA: CircRNA-RBP interaction sites identification using sequence structural attention model.

Due to the ability of circRNA to bind with corresponding RBPs and play a critical role in gene regulation and disease prevention, numerous identification algorithms have been developed. Nevertheless, most of the current mainstream methods primarily capture one-dimensional sequence features through various descriptors, while neglecting the effective extraction of secondary structure features. Moreover, as the number of introduced descriptors increases, the issues of sparsity and ineffective representation also rise, causing a significant burden on computational models and leaving room for improvement in predictive performance. Based on this, we focused on capturing the features of secondary structure in sequences and developed a new architecture called CRBPSA, which is based on a sequence-structure attention mechanism. Firstly, a base-pairing matrix is generated by calculating the matching probability between each base, with a Gaussian function introduced as a weight to construct the secondary structure. Then, a Structure_Transformer is employed to extract base-pairing information and spatial positional dependencies, enabling the identification of binding sites through deeper feature extraction. Experimental results using the same set of hyperparameters on 37 circRNA datasets, totaling 671,952 samples, show that the CRBPSA algorithm achieves an average AUC of 99.93%, surpassing all existing prediction methods. CRBPSA is a lightweight and efficient prediction tool for circRNA-RBP, which can capture structural features of sequences with minimal computational resources and accurately predict protein-binding sites. This tool facilitates a deeper understanding of the biological processes and mechanisms underlying circRNA and protein interactions.

Mathematical Modelling from a Semiotic-Cognitive Approach

Mathematical modelling has acquired relevance in different fields at an international level, both in education and research. This article states that, throughout the construction of the theoretical corpus of this mathematical process and competency – among others – two big issues have occurred: one of terminological nature since the definitions surrounding modelling have varied, and other of representational nature since different representations have been proposed to explain modelling as a cyclical process. These two issues occur mainly due to the diversity of positions on how modelling is understood and how this process is tried to be explained. To address the terminological issue, a position was adopted on the terminology surrounding modelling in Mathematics Education, based on the main theoretical developments of ICTMA Community. To address the representational issue, a modelling cycle from a semiotic-cognitive approach that represents this process in a non-set way is proposed, that is, without a strict separation between «real world» and «mathematical world». In this way, a proposal aligned with a system of theoretical principles (terminology and structure), a methodology (modelling cycle), and sketches of research questions (for future theoretical and empirical developments) is presented to address both issues.

Intergovernmental discontent in rural areas: A perspective from local councils in Spain during the Great Recession

Left-behind places have gained attention during the last years and among those, particular attention has been paid to rural areas, where discontent finds anchor in an articulated narrative of distinctiveness that separates rural and urban, and on which populist parties would have tapped. Thus, rural discontent can be considered a specific expression of disaffection of left-behind places, shaped and characterised by the processes and narratives that are particular to rural areas. Understanding the social justice structure of the discontent is essential to identify the critical elements contributing to a revival of rural-urban cleavages and rethink the development paths in rural areas that feel left behind.To advance on the qualitative understanding of the configuration of the left-behind places, this contribution explores discontent among rural mayors in a Spanish region -Valencia- during the Great Recession. Building on qualitative evidence and using a social justice approach, the presentation will explore the institutional factors driving rural discontent. The results describe the emergence of rural discontent rooted in perceptions of intergovernmental inequality upon redistribution, recognition and representation issues that are shaped by demographic, political and environmental features of rurality.

Navigating Ethical Tensions Through Critical Reflexivity: A Participatory Filmmaking Research Project With Children With Disabilities

This paper illustrates the importance of critical reflexivity in guiding socially and ethically responsible participatory research through an analysis of reflexive notes pertaining to the process of a participatory filmmaking research project with children with disabilities. Within this process, numerous ethical tensions emerged in the field regarding the participation of children with disabilities, authenticity of stories shared, navigating facilitator’s voice, issues of representation of child co-researchers, safety and risks associated with sharing everyday realities within the film, and limits to immediate action. The practice of individual and shared critical reflexivity among researchers, and inclusivity of child co-researchers, was central in navigating ethical tensions. This paper makes transparent the process of critical reflexivity within a participatory action research project by highlighting the ethical tensions faced, contextualizing them within cultural practices and power relations, and sharing strategies used to address ‘ethics in practice.’ We end by proposing practical strategies to enhance reflexive research practices in participatory work.

Publishing mathematics education research in English: amplifying voices from the field

AbstractIn this paper we investigate the issue of representation within the Journal of Mathematics Teacher Education (JMTE) and the broader academic publishing landscape, particularly focusing on the underrepresentation of authors from various world regions. A questionnaire, distributed globally, aimed to amplify the voices of the underrepresented, exploring the constraints and affordances of publishing in English-medium mathematics education research journals. The question that guided our investigation was: What do voices from the mathematics education community raise in their responses to questions about publishing in English-medium research journals like JMTE? We used qualitative methods to review the responses and identify common themes. The findings revealed significant barriers and challenges related to language, research location, and institutional support, highlighting the complexities of navigating the global academic community and the academic publishing culture. We propose actionable suggestions to foster a more equitable, diverse, and inclusive publishing environment.

Addressing equity, diversity, and inclusion in JBI qualitative systematic reviews: a methodological scoping review.

The objective of this methodological scoping review was to investigate ways in which qualitative review teams are addressing equity, diversity, and inclusion (EDI) in the process of conducting and reporting qualitative systematic reviews that use JBI guidelines. To promote health equity, there is a need for evidence synthesis processes and practices to develop approaches that incorporate EDI. Some guidance is available to guide equity-focused review methods and reporting, but this is primarily oriented to quantitative systematic reviews. There is currently limited knowledge about how review teams are addressing EDI within qualitative evidence syntheses. This review included English-language qualitative systematic reviews, published in 2022, that used all the steps outlined in JBI guidance for qualitative reviews. A 1-year sample of published reviews was identified from a search undertaken on March 17, 2023, of 2 health care databases: MEDLINE (Ovid) and CINAHL (EBSCOhost). Data extraction followed a framework approach, using an adapted preexisting equity template. This included attention to i) the reporting of a range of characteristics associated with EDI, ii) search approaches, and iii) analytical approaches (including reflexivity, intersectionality, and knowledge user engagement). Data were analyzed using descriptive statistics and narrative summary. Forty-three reviews met the inclusion criteria. The majority of reviews (n=30) framed their questions and aims in a generic/universal (rather than EDI-focused) way. Six reviews justified their population focus in terms of an EDI-related issue. Only one review included a knowledge user. The sociodemographic and other key characteristics of the samples in underpinning studies were poorly reported, making it hard to discern EDI-related issues or to undertake EDI-related analyses. Thirteen of the reviews included non-English-language evidence sources, and 31 reviews included gray literature sources. Ten reviews demonstrated an element of intersectional or otherwise critical approaches within their analyses of categories and synthesized findings (whereby issues of power and/or representation were explicitly considered). Only 8 reviews included discussions of review team composition and reflexivity within the review process. This EDI-focused methodological enquiry has highlighted some limitations within current qualitative evidence synthesis practice. Without closer attention to EDI, there is a danger that systematic reviews may simply serve to amplify, rather than illuminate, existing gaps, silences, and inequitable knowledge claims based on dominant representations. This review sets out a range of suggestions to help qualitative evidence synthesis teams to more systematically embed EDI within their methods and practices.

­Soviet ‘Easterns/Osterns’ of the 1920s: Adventure Films on the Caucasian Frontier of Russia

The article elucidates the issue of representation in Soviet cinema of historical events that transpired during the formation of the Caucasian frontier and the interactions that emerged between the indigenous population and the tsarist troops. The term “Eastern” is analogous to the term “Western” which refers to films about the exploration of the Wild West. This is a useful way of conceptualizing Soviet silent films created on Caucasian material from the 19th–early 20th centuries. This article aims to examine feature films from the 1920s that depict Russia’s advance into the Caucasus. It seeks to identify similarities and differences between these films and the first Soviet “Easterns/Osterns” and “Westerns,” as well as to analyze the influence of ideological attitudes in historical science on the interpretation and depiction of events that took place on the Caucasian frontier. The visual sources utilized in this study include the silent films ‘Abrek Zaur’ (1926), ‘The Law of the Mountains’ (1927), and ‘Zelimkhan’ (1929). Additionally, published materials from the 1920s, including periodicals such as newspapers and magazines, were consulted. The study yielded insights into the stylistic similarities between classic Westerns and the first Soviet Easterns, including the portrayal of protagonists, the use of action and stunts, and the incorporation of jumps. The content of the films is correlated with real historical events, but they reflect the Bolshevik paradigm of history in the study of ethnosocial conflicts in the Caucasus. In films about highlanders, masculine culture is a dominant feature due to gender attitudes and the national cultural identity of the peoples of the Caucasus. Films about mountaineers were instrumental in shaping perceptions of the Caucasus during the early decades of the twentieth century. They illustrate the attributes of traditional culture, daily life, customs of mountain village inhabitants, the characteristics of the landscape, and architectural features. In general, films of an adventurous nature created on Caucasian material are of interest to those with an affinity for classic cinema, particularly the earliest Soviet Eastern films, as well as to researchers seeking to gain insight into significant historical and cultural information. This article is intended for those engaged in the study of the history of Soviet cinema.

HOW DOES WOMEN IN SECURING ELECTORAL VOTE IN INDONESIAN POLITIC? INSIGHT FROM SOUTH SUMATERA PROVINCE

The issue of women's representation in politics has become an interesting discourse in various countries, even in Indonesia. The advancement of female candidates needs to be appreciated in the midst of the patriarchal culture that is still inherent in Indonesia. The presence of women in politics cannot be separated from the role of family ties. This is the focus and purpose of this article, which is to describe the family ties that influence women's electability in politics. The research method used in this article is a qualitative-descriptive method through literature study to explain the family ties factor in Ratu Tenny Leriva's representation as a senator for the 2024 South Sumatra Electoral District. Using the theoretical framework of the Richter model of family ties, this study reveals that Ratu Tenny Leriva's election cannot be separated from Herman Deru's position and influence. As a former Governor, Regent, and Chairman of the Regional Representative Council of the NasDem Party in South Sumatra, Herman Deru facilitated Ratu Tenny Leriva in building a positive image, popularity, and electability, despite being a new-comer and still 23 years old. This can be seen from Ratu Tenny Leriva's involvement in various public spaces and campaign periods, where many billboards or posters include Herman Deru's photo. This family bond is an important factor and political modality in Ratu Tenny Leriva's electability in South Sumatra in 2024.

A feature-enhanced knowledge graph neural network for machine learning method recommendation.

Large amounts of machine learning methods with condensed names bring great challenges for researchers to select a suitable approach for a target dataset in the area of academic research. Although the graph neural networks based on the knowledge graph have been proven helpful in recommending a machine learning method for a given dataset, the issues of inadequate entity representation and over-smoothing of embeddings still need to be addressed. This article proposes a recommendation framework that integrates the feature-enhanced graph neural network and an anti-smoothing aggregation network. In the proposed framework, in addition to utilizing the textual description information of the target entities, each node is enhanced through its neighborhood information before participating in the higher-order propagation process. In addition, an anti-smoothing aggregation network is designed to reduce the influence of central nodes in each information aggregation by an exponential decay function. Extensive experiments on the public dataset demonstrate that the proposed approach exhibits substantial advantages over the strong baselines in recommendation tasks.

Time-dependent scalings and Fock quantization of a massless scalar field in Kantowski–Sachs

Abstract We address the issue of inequivalent Fock representations in quantum field theory in a curved homogenous and anisotropic cosmological background, namely Kantowski–Sachs spacetime, which can also be used to describe the interior of a nonrotating black hole. A family of unitarily equivalent Fock representations that are invariant under the spatial isometries and implement a unitary dynamics can be achieved by means of a field redefinition that consists of a specific anisotropic scaling of the field configuration and a linear transformation of its momentum. Remarkably, we show that this kind of field redefinition is in fact unique under our symmetry and unitary requirements. However, the physical properties of the Hamiltonian dynamics that one obtains in this way are not satisfactory, inasmuch as the action of the Hamiltonian on the corresponding particle states is ill defined. To construct a quantum theory without this problem, we need a further canonical transformation that is time- and mode-dependent and is not interpretable as an anisotropic scaling. The old and new Fock representations, nevertheless, are unitarily equivalent. The freedom that is introduced when allowing for this further canonical transformation can be fixed by demanding an asymptotic diagonalization of the Hamiltonian and a minimal absorption of dynamical phases. In this way, the choice of vacuum and the associated Fock representation are asymptotically determined.

Civil society ethos? Attitude differences between civil society elites and the population in Sweden

Previous studies have found that elites differ from the general population not only in terms of their demographic and social composition but also with respect to policy preferences and attitudes. When it comes to civil society organisations, the issue of representation and representativeness of top-level leadership is of particular relevance, since a small number of individuals are expected to act on behalf of groups and causes that are not well acknowledged or even suppressed by other societal actors. Using two survey studies, this study compares the demographic composition and attitudes of the top-level leaders of the most resourceful civil society organisations in Sweden with those of the general population. We find that civil society elites are not demographically representative of the general population and that they also differ in attitudes when it comes to levels of trust, political orientations, satisfaction with democracy, and acceptance of income inequality. What is more interesting, however, is that the differences in attitudes cannot be fully explained by the skewed demographic characteristics of the civil society leaders, indicating that there might be distinctive sets of values and attitudes underpinning a ‘civil society ethos’.

Tallinn’s Freedom Square as a heterogeneous public space

ABSTRACT The paper looks at the mental and physical transformations of Freedom (Vabaduse) Square, the main square of Tallinn, in the 1980s–1990s transition period, analyzing developments that were at times antagonistic and conflictual, and at times a mutually supportive dialogue of architectural and artistic projects with the everyday space. In these dialogues, the square appears as an important locus of the construction of the public sphere and a place for the formation and negotiation of different publics and counter-publics. The analysis also reveals the developmental dynamics of the period, with the beginning of the 1990s manifesting more openness and more social antagonisms but also more pragmatic and commercial attitudes, and the end of the decade showing a shift to concerns about representational and symbolic issues.

Digitalizing cultural heritage through metaverse applications: challenges, opportunities, and strategies

A human-animal problematic and the production of pedagogical clearings in the classroom

This paper springboards from entanglements involving humanisms, classroom teaching, and eco-disaster. Drawing on Derrida’s l’animot, Marchesini’s theriomorphism and animal epiphany, and Rice and Rud’s blurring, we mine the deep potentials in postfoundationalist approaches to distinction-making and violence in regard to a human-animal problematic. The approaches taken via these different “theoretical” engagements suffuse autoethnographic-style accounts of two classroom-based instances in an upper elementary school in the midwestern United States. These instances introduce the notion of pedagogical clearings, challenging fixed and power-laden notions of “self.” Students’ responses, issues of representation (-isms of humanism), and “multispecies” insights that co-presenced in instructional spaces are discussed. We argue that a static-circular economy of [“human”] self that underwrites eco-crises can be temporarily decentered and deferred per Derrida and blurred and suspended per Marchesini and Rice and Rud, experienced as glimpses of “non-anthropocentric” possibilities, offering fleeting, significant instances of l’animot.

A Comprehensive Examination of Workforce Diversity

Workforce diversity has become a crucial topic in organizational management due to its significant effects on workplace dynamics, innovation, and performance. Although our understanding of diversity has grown, its comprehensive impact across various sectors and organizational settings is still not fully understood. This review aims to integrate current knowledge on the many sides of workforce diversity, assess its challenges, and explore opportunities for boosting organizational effectiveness. This study performed a thorough 32 literatures using Nepal Journals Online (NepJOL), an online publication of Nepalese journals, targeting publications from January 2019 to May 2024. Search terms included "workforce diversity," "diversity in organizations," and "cultural diversity," among others. The selection included studies that assessed the effects of diversity using both qualitative and quantitative approaches. The review highlights mixed findings on the correlation between workforce diversity and organizational performance, emphasizing the complexity of diversity's impact. Key themes include the importance of inclusive workplace cultures, challenges in multicultural communication, gender representation issues, and knowledge gaps in diverse sectors. Analysis of publication trends reveals a growing recognition of diversity's significance, particularly in recent years. Workforce diversity is crucial for organizational success, yet its impact varies across contexts. Prioritizing inclusive workplace cultures and addressing diversity-related challenges are essential. Future research should focus on longitudinal studies, sector-specific investigations, and innovative approaches to promote diversity and inclusion. Embracing diversity as a strategic asset can drive innovation and sustainable growth in diverse global environments.

An imbalanced learning method based on graph tran-smote for fraud detection

Fraud seriously threatens individual interests and social stability, so fraud detection has attracted much attention in recent years. In scenarios such as social media, fraudsters typically hide among numerous benign users, constituting only a small minority and often forming “small gangs”. Due to the scarcity of fraudsters, the conventional graph neural network might overlook or obscure critical fraud information, leading to insufficient representation of fraud characteristics. To address these issues, the tran-smote on graphs (GTS) method for fraud detection is proposed by this study. Structural features of each type of node are deeply mined using a subgraph neural network extractor, these features are integrated with attribute features using transformer technology, and the node’s information representation is enriched, thereby addressing the issue of inadequate feature representation. Additionally, this approach involves setting a feature embedding space to generate new nodes representing minority classes, and an edge generator is used to provide relevant connection information for these new nodes, alleviating the class imbalance problem. The results from experiments on two real datasets demonstrate that the proposed GTS, performs better than the current state-of-the-art baseline.
