Real-time signature-based detection and prevention of DDOS attacks in cloud environments
Authors: Mahesh Kumar Bagwani  , Anshu Gangwar  , Karuna Vishwakarma  , Virendra Kumar Tiwari
Published: September 2024

Security in cloud environments is paramount due to the increasing prevalence of Distributed Denial of Service (DDoS) attacks, which can severely disrupt services and cause significant financial and data losses. Traditional security mechanisms, such as Intrusion Detection Systems (IDS) and Firewalls, often struggle to detect and mitigate novel, evolving threats due to the lack of predefined detection signatures. This paper proposes a real-time signature-based detection mechanism tailored specifically for cloud environments. The proposed system generates signatures in real-time, enabling the identification and prevention of emerging DDoS attacks. The effectiveness of the solution is validated through extensive experimental evaluations, demonstrating its ability to reduce attack impact and enhance cloud security.

Linjaguar: circulação, poética e tradução de cantos rituais krahô (Timbira/Brasil central)
Authors: Packer Ian
Published: September 2024

RESUMO: neste ensaio, apresento alguns experimentos de tradução de um gênero de canto ritual krahô (povo ameríndio de língua Jê que vive no norte do estado do Tocantins). Apesar de serem bastante concisos, tais cantos colocam uma série de desafios à tradução, em razão da presença de muitas palavras sem sentido, de distorções fonológicas e de outros elementos verbomusicais que opacificam seu sentido. Por meio da discussão etnográfica detalhada dos regimes de criação, circulação e enunciação de tais cantos, argumento que essas características não devem ser abandonadas, e sim ocupar o centro do esforço de tradução, inspirando-me para isso em propostas feitas por autores como Rothenberg (2006) e Gontijo Flores & Capilé (2022).

Authors: Alsamawi A.I. , Al-Sharqi S.A.H. , Mubarak H.J.
Published: September 2024

The abnormal umbilical cord coiling pattern affects the well-being of the newborn in different ways. Moreover the differentiation of mast cell according to these patterns may also varies. The objective: to investigate the detection and enumeration of mast cells in different patterns in human coiling cords in order to explore their effect on the newborn baby health.Materials and methods. Umbilical cord samples were collected from 105 healthy pregnant women. The cords were collected immediately after labor and kept in formalin (10%), according to coil type. Three major categories of umbilical cord coiling (normocoiled, hypercoiled, and hypocoiled) were determined according to the Umbilical Cord Index (UCI).The histological sections of the umbilical cord were collected according to UCI. This step is followed by using different histological stains, including hematoxylin and eosin and toluidine blue stains. The expression of the CD117 mast cell population in the umbilical cord tissue was determined using the immunohistochemical method in the subamniotic, perivascular and central areas. The enumeration of mast cells was done by direct counting and using Image J software. Results. The comparison of mast cell counts using Image J showed statistically significant variations (P<0.05) between normocoiled and hypercoiled cords in mast cell populations. No significant changes (P>0.05) were found in mast cell counts between normocoiled and hypocoiled umbilical cords. Conclusions. The mast cell distribution interpretation suggested that mechanical coiling during embryonic growth affects mast cell dispersal in sectioned umbilical cords. This interpretation’s functional relevance should be applied to coiling events that do not have harmful outcomes on the fetus. Future research could be done on the distribution of mast cells in the abnormally coiled umbilical cords associated with negative perinatal outcomes.
The impact of problem-based learning on motivation and mathematics outcome for sixth-grade students
Authors: Kho Ronaldo , Solihati Titi , Lumbantobing Happy
Published: September 2024

Numerous studies have demonstrated that the implementation of problem-based learning (PBL) can enhance student motivation and learning outcomes. However, the integration of contextual media in these instructional activities remains limited. This research aims to investigate the impact of using PBL with contextual media on student outcomes, compare the differences in mathematics achievement between students taught through PBL with contextual media and those taught through conventional methods, and assess variations in student motivation between these two instructional approaches. A quasi-experimental design with a non-equivalent pretest-posttest control group was employed in this study. The participants consisted of 60 sixth-grade students, divided into an experimental group (taught using PBL with contextual media) and a control group (taught using conventional methods). Data were collected through learning motivation questionnaires and objective mathematics tests, with data analysis conducted using normalized gain scores (N-Gain) and t-tests. The results indicated significant improvements in student outcomes when taught using PBL with contextual media. Additionally, there was a marked difference in mathematics achievement between the experimental and control groups, as well as differences in student motivation between the two instructional methods. These findings suggest that implementing PBL with contextual media presents a promising strategy for enhancing both student motivation and mathematics learning outcomes.

Background. Mitochondria can influence cancer cells both indirectly via reactive oxygen species mediation and directly through mitochondrial biogenesis. Energy production in mitochondria is crucial as it facilitates the synthesis of essential molecules needed for cellular biosynthesis, growth, and proliferation. The development of new anticancer drugs that target the energy metabolism of tumor cells shows promise in cancer treatment. Our study aimed to investigate how the thiazole derivative N-(5-benzyl-1,3-thiazol-2-yl)-3,5-dimethyl-1-benzofuran-2-carboxamide (BF1), the polymeric nanoparticles based on the polyethylene glycol (PEG-PN, Th5), and their complex with BF1 (Th6) affect respiration and mitochondrial membrane potential in murine NK/Ly tumor cells. Materials and Methods. The study was performed on white wild-type male mice with grafted NK/Ly lymphoma. The test substances were added to the cell suspension at a final concentration of 10 μM and incubated for 15 min at 37 °C. Oxygen uptake rates in NK/Ly cells were measured using a polarographic method with Clark electrode. Changes in mitochondrial membrane potential were assessed using the tetramethylrhodamine methyl ester fluorescence dye. The fluorescence intensity was evaluated using the ImageJ computer program. Results. After incubating NK/Ly cells with BF1 (10 µM), Th5, or the BF1 + PEG-PN complex (Th6) for 15 min, no changes were observed in glucose-fueled basal respiration. However, the Th6 complex significantly activated FCCP-stimulated respiratory processes in NK/Ly lymphoma cells. Fluorescent microscopy data indicated that BF1 or Th5 alone did not affect mitochondrial membrane potential values. However, the Th6 complex significantly decreased mitochondrial membrane potential, suggesting a reduction in NK/Ly cell viability. Conclusions The investigated complex of thiazole derivative BF1 with PEG-based polymeric nanoparticles may realize its cytotoxic effect by depolarization of mitochondrial membrane in NK/Ly lymphoma cells.

Pantocsekiella minuscula (Bacillariophyta), a new diatom species to Russia
Authors: Genkal S. I. , Sharov А. N.
Published: September 2024

Several small-sized centric diatom Pantocsekiella species were identified during a study of phytoplankton in the Krasnoyarsk Reservoir (Krasnoyarsk Territory, Russia) with the use of scanning electron microscopy. One of them, Pantocsekiella minuscula, is new for Russia. This species was previously known only from Europe (North Macedonia) and North America (USA, Canada). Comparison of such features as the diameter of the valve and its central area and the density of marginal fultoportulae is revealed differences from the original description of this species. Variability in the presence/absence and location of granules on the valve face was also shown, all of which enabled us to amend the species description. The new data on the occurrence of P. minuscula allowed us to expand the species distribution.
Using LLMs to Detect Group Appeals in Parties’ Election Manifestos
Authors: Horne Will , Dolinsky Alona Olga , Huber Lena Maria
Published: September 2024

A growing political science scholarship substantively distinguishes between parties’ group appeals and policy appeals, the latter referring to the policies parties claim to support or oppose and the former relating to the specific social groups mentioned in party statements. While both are prevalent in parties’ campaign materials, existing large-scale datasets focus primarily on policy-based appeals, with little data available for empirical analyses of group-based appeals. Moreover, the extensive resources needed to generate these data via hand-coding and the complexity of automating such text analysis, provides challenges to new collection efforts. However, examining group appeals is substantively important for understanding party behavior, representation, and electoral politics. In this paper, we propose to address this gap by automating the extraction of group appeals from political texts using recent advances in computational text analysis to identify the social groups mentioned and the stance towards these groups (whether the appeals are supportive or critical). We use manifestos of major British, Irish, German and Austrian parties as test cases, demonstrating the benefits of our approach for revealing important trends in party behavior, with implications for party competition, voter behavior, and representation.
Enhancing Feelings-of-Familiarity for Dynamic Scenes by Manipulating Relevance-of-Processing
Authors: McNeely-White Katherine , Liégeois-Chauvel Catherine , Yonelinas Andrew , Pedersen Nigel
Published: September 2024

Encountering a novel scene can sometimes lead to feelings of familiarity. Prior work suggests thatthis can be driven by previous exposure to a configurally similar scene, despite that scene failingto be explicitly recalled. The extent to which these metamemorial sensations for scenes are affectedby encoding manipulations is poorly understood, as most research examining encodingmanipulation effects on familiarity and recollection has implemented standard word list-learningparadigms. The current study examined how encoding manipulations impacted familiarity andrecollection induced by having participants tour dynamic scenes under different encodingconditions (Passive Viewing, Self-Generation, Indoor/Outdoor Judgment), then tour test scenesthat were either configurally similar to studied scenes or entirely novel. Results indicated that,compared to passively viewing, orienting participants toward perceptual aspects of scenes (i.e.,requiring an indoor/outdoor judgment) boosted familiarity-based discrimination and decreasedrecollection. In contrast, requiring participants to engage in elaborative encoding (i.e., self-generate descriptive study scene names) led to an increase in recollection but did not increasefamiliarity-based discrimination compared to the passive condition. These results fit with thebroader verbal learning literature, which suggests that familiarity is sensitive to perceptualmanipulations, whereas recollection is sensitive to elaborative processing, while alsodemonstrating the effects of encoding manipulations on memory for scenes. We propose that therelevance of the encoded features has a greater impact on subsequent memory performance, asorienting participants to the scene’s perceptual properties boosts familiarity, while focusing onelaborative task-relevant processing of the individual scenes boosts recollection.
Inconclusive reinforcing effects between reading and mathematics: Scrutiny of the random-intercept cross-lagged panel model
Authors: Sorjonen Kimmo , Melin Bo
Published: September 2024

Studies, e.g., using the random-intercept cross-lagged panel model (RI-CLPM), have indicated reinforcing prospective effects between reading and math achievement. However, effects in the RI-CLPM may be biased and spurious. Here, we analyzed data from a nationally representative sample of U.S. children (the Early Childhood Longitudinal Study - Kindergarten Class of 2010-11 (ECLS-K: 2011), N = 17,487) with the RI-CLPM as well as complementary models, e.g., multilevel models (MLM) of person-mean centered scores. The models indicated discrepant and inconclusive reinforcing and degrading prospective effects between reading and math achievement. Consequently, prospective effects between reading and math may have been spurious and conclusions of reinforcing effects would appear premature. It is important for researchers to bear in mind that correlations, including effects in the RI-CLPM, do not prove causality. For improved inference, researchers are recommended to triangulate and fit complementary models to their data in order to evaluate if effects from one model, e.g., the RI-CLPM, are corroborated or if they may be spurious.
Exposure to Misinformation Does Not Increase Truth Relativism

Though much research on fake news and misinformation has focused on individual differences in the ability to detect and transmit fake news (e.g., reasoning strategies, identity, emotions, political affiliation), less well understood is how fake news influences people’s attitudes towards true news. The present study investigates whether exposure to misinformation increases truth relativism—the view that the news is neither completely true nor completely false. To evaluate this, we develop a measure of truth relativism based on the relative truth or falsity of news headlines. In four experiments exposing people to different levels of fake news, we found that truth relativism is not affected by differential exposure to fake news (Bayesian meta-analysis BF01=133.13). However, people’s truth relative views of headlines was consistent with their own self-reported truth relativism using a self-report survey. Our results indicate that truth relativism is a trait, not a state, and that this state is impervious to misinformation.
Communicating causal effect heterogeneity

Advances in experimental, data collection, and analysis methods have brought population variability in psychological phenomena to the fore. Yet, current practices for interpreting such heterogeneity do not appropriately treat the uncertainty inevitable in any statistical summary. Heterogeneity is best thought of as a distribution of features with a mean (average person’s effect) and variance (between-person differences). This expected heterogeneity distribution can be further summarized e.g. as a heterogeneity interval (Bolger et al., 2019). However, because empirical studies estimate the underlying mean and variance parameters with uncertainty, the expected distribution and interval will underestimate the actual range of plausible effects in the population. Using Bayesian hierarchical models, and with the aid of empirical datasets from social and cognitive psychology, we provide a walk-through of effective heterogeneity reporting and display tools that appropriately convey measures of uncertainty. We cover interval, proportion, and ratio measures of heterogeneity and their estimation and interpretation. These tools can be a spur to theory building, allowing researchers to widen their focus from population averages to population heterogeneity in psychological phenomena.

Anti-science movements brought more than public distrust in science. Perhaps even more worryingly, these movements are also associated with instances of harassment of – and violence against – scientists. However, virtually nothing is known about individuals likely to harass or harm scientists. Across two pre-registered studies (total N=749), we investigated the role of worldviews (e.g., political ideology, conspiracy mentality, science cynicism), radicalization risk factors (relative deprivation and threat), and personality traits and how these relate to harassment of scientists (both attitudes and behavior). We found that science cynicism–the perception that scientists are incompetent and corrupt–drives approval of scientists’ harassment (attitudes), as well as harmful behavior (e.g., refusing to donate money, not signing a petition). Additionally, perceiving scientists as threatening, as well as dark personality traits (psychopathy and narcissism), contributed to approving scientists’ harassment. Overall, the present research takes a first step in identifying predictors of the willingness to harm scientists.
Ensuring Transparency and Trust in Supervised Machine Learning Studies: A Checklist for Organizational Researchers

Machine learning (ML) algorithms are rapidly being incorporated into the work of organizational practitioners, given their capability and flexibility in analyzing big data (i.e., large-scale messy datasets). However, in organizational science, ML is still in its relative infancy, and in both research and practice arenas, there is little consistency in reporting ML information. This lack of consistency in result reporting is concerning because ML offers a wide range of analytic options. Therefore, it is important that organizational research and practice in ML are conducted in a transparent, understandable, and ethical manner. To address this concern, we summarize the necessary information to report in organizational studies using supervised ML, along with examples of how such information has been reported to-date in published organizational studies. We earnestly hope that organizational researchers will benefit from this checklist about ML result reporting, adapting and extending it further in the future.

Psychological research has provided important insights into the processing of misinformation and conspiracy theories. Traditionally, this research has focused on randomized laboratory experiments and observational (non-experimental) studies seeking to establish causality via third-variable adjustment. However, laboratory experiments will always be constrained by feasibility and ethical considerations, and observational studies can often lead to unjustified causal conclusions or confused analysis goals. We argue that research in this field could therefore benefit from clearer thinking about causality and an expanded methodological toolset that includes natural experiments. Using both real and hypothetical examples, we offer an accessible introduction to the counterfactual framework of causality and highlight the potential of instrumental variable analysis, regression discontinuity design, difference-in-differences, and synthetic control for drawing causal inferences. We hope that such an approach to causality will contribute to greater integration amongst the various misinformation- and conspiracy- adjacent disciplines, thereby leading to more complete theories and better applied interventions.
Credit Risk Management and Profitability of Nepalese Commercial Banks
Authors: Sigdel Kamal , Deswal Kirti
Published: September 2024

Banks are an essential component in the economy in the process of creating economic growth in both developed and developing countries. In order to contribute to its commitment to promote growth, banks should be able to lock in on the stability of their financial performance. This study has examined the relationship of credit risk management on performance of Nepalese commercial banks. The descriptive, Correlational research design and review have been adopted for the study. The pooled data of ten commercial banks out of total population of twenty commercial banks operating up to January 2024 has been analyzed. The findings indicate that specific financial indicators, such as credit to deposit ratio, non-performing loan, and interest spread rate, play crucial roles in influencing ROA and ROE. Major issue on non-performing loan and impairment cost were highlighted. Identified that gross domestic product growth rate has an insignificant positive impact on profitability of commercial banks in Nepal.
These insights contribute to a deeper understanding of the dynamics within the banking sector, offering valuable implications for stakeholders and policymakers.

Evapotranspiracija je važan dio hidrološkog ciklusa vode, kao i važna komponenta u planiranju navodnjavanja i određivanja sušnog razdoblja. Cilj je ovog istraživanja usporediti iznose potencijalne evapotranspiracije prema različitim metodama izračuna u različitim klimatskim tipovima, kao i korelacije među njima. Potencijalna evapotranspiracija (mm) izračunata je prema metodama Thornthwaitea, Ivanova, Blaney-Criddlea i Penman- Monteitha za meteorološke postaje Osijek, Zagreb-Maksimir, Parg, Zavižan i Hvar. Meteorološka postaja Osijek ima Cfa tip klime, umjereno topla kišna klima s vrućim ljetom. Meteorološke postaje Zagreb-Maksimir i Parg imaju Cfb tip klime, umjereno toplu vlažnu klimu s toplim ljetom, meteorološka postaja Zavižan ima Df tip klime, vlažna borealna klima, dok se meteorološka postaja Hvar nalazi u području sredozemne klime s vrućim ljetom (Csa tip klime). Na području nizinske Hrvatske u Cfa i Cfb tipovima klime prosječno najmanji iznos potencijalne evapotranspiracije bio je prema metodi Blaney-Criddlea (709,30 mm), a najveći prema metodi Ivanova (859,95 mm). Za meteorološku postaju Parg u gorskoj Hrvatskoj, prosječno najmanji iznos potencijalne evapotranspiracije bio je prema metodi Ivanova (553,01 mm), dok je najveći iznos bio prema metodi Penman-Monteitha (705,87 mm). Na Hvaru najmanji iznos potencijalne evapotranspiracije bio je prema metodi Thornthwaitea (891,57 mm), a najveći prema metodi Ivanova u iznosu od 1368,55 mm. Prema prosječnim godišnjim vrijednostima potencijalne evapotranspiracije metodi Penman-Monteitha bila je najbliža metoda Ivanova na području nizinske Hrvatske te metoda Blaney-Criddlea na području gorske, pretplaninske i sredozemne Hrvatske. Najveća korelacija (r = 0,98*) bila je između metode Thornthwaitea i Blaney-Criddla, a najmanja (r = 0,49*) utvrđena je između metoda Ivanova i Blaney-Criddlea. S metodom Pennman-Monteitha najviše su korelirale metode Thornthwaitea i Ivanova u nizinskoj Hrvatskoj te Thornthwaitea i Blaney-Criddlea u gorskoj, pretplaninskoj i sredozemnoj Hrvatskoj.
