DuckPGQ: Bringing SQL/PGQ to DuckDB
Authors: Wolde Daniel ten , Szárnyas Gábor , Boncz Peter
Published: September 2023

We demonstrate the most important new feature of SQL:2023, namely SQL/PGQ, which eases querying graphs using SQL by introducing new syntax for pattern matching and (shortest) path-finding. We show how support for SQL/PGQ can be integrated into an RDBMS, specifically in the DuckDB system, using an extension module called DuckPGQ. As such, we also demonstrate the use of the DuckDB extensibility mechanism, which allows us to add new functions, data types, operators, optimizer rules, storage systems, and even parsers to DuckDB. We also describe the new data structures and algorithms that the DuckPGQ module is based on, and how they are injected into SQL plans.

While the demonstrated DuckPGQ extension module is lean and efficient, we sketch a roadmap to (i) improve its performance through new algorithms (factorized and WCOJ) and better parallelism and (ii) extend its functionality to scenarios beyond SQL, e.g., building and analyzing Graph Neural Networks.
Demo of QueryBooster: Supporting Middleware-Based SQL Query Rewriting as a Service
Authors: Bai Qiushi , Alsudais Sadeem , Li Chen
Published: September 2023

Query rewriting is an important technique to optimize SQL performance in databases. With the prevalent use of business intelligence systems and object-relational mapping frameworks, existing rewriting capabilities inside databases are insufficient to optimize machine-generated queries. In this paper, we propose a novel system called "QueryBooster," to support SQL query rewriting as a cloud service. It provides a powerful and easy-to-use Web interface for users to formulate rewriting rules via a language or express rewriting intentions by providing example query pairs. It allows multiple users to share rewriting knowledge and automatically suggests shared rewriting rules for users. It requires no modifications or plugin installations to applications or databases. In this demonstration, we use real-world applications and datasets to show the user experience of QueryBooster to rewrite their application queries and share rewriting knowledge.
SHEVA: A Visual Analytics System for Statistical Hypothesis Exploration
Authors: de Almeida Vicente Nejar , Ribeiro Eduardo , Bouarour Nassim , Comba João Luiz Dihl , Amer-Yahia Sihem
Published: September 2023

We demonstrate SHEVA, a System for Hypothesis Exploration with Visual Analytics. SHEVA adopts an Exploratory Data Analysis (EDA) approach to discovering statistically-sound insights from large datasets. The system addresses three longstanding challenges in Multiple Hypothesis Testing: (i) the likelihood of rejecting the null hypothesis by chance, (ii) the pitfall of not being representative of the input data, and (iii) the ability to navigate among many data regions while preserving the user's train of thought. To address (i) & (ii), SHEVA implements significance adjustment methods that account for data-informed properties such as coverage and novelty. To address (iii), SHEVA proposes to guide users by recommending one-sample and two-sample hypotheses in a stepwise fashion following a data hierarchy. Users may choose from a collection of pre-trained hypothesis exploration policies and let SHEVA guide them through the most significant hypotheses in the data, or intervene to override suggested hypotheses. Furthermore, SHEVA relies on data-to-visual element mappings to convey hypothesis testing results in an interpretable fashion, and allows hypothesis pipelines to be stored and retrieved later to be tested on new datasets.
Towards Auto-Generated Data Systems

Published: September 2023

After decades of progress, database management systems (DBMSs) are now the backbones of many data applications that we interact with on a daily basis. Yet, with the emergence of new data types and hardware, building and optimizing new data systems remain as difficult as the heyday of relational databases. In this paper, we summarize our work towards automating the building and optimization of data systems. Drawing from our own experience, we further argue that any automation technique must address three aspects: user specification, code generation, and result validation. We conclude by discussing a case study using videos data processing, along with opportunities for future research towards designing data systems that are automatically generated.
Common Sense: The Dark Matter of Language and Intelligence (VLDB 2023 Keynote)
Authors: Choi Yejin
Published: September 2023

Scale appears to be the winning recipe in today's leaderboards. And yet, extreme-scale neural models are (un)surprisingly brittle and make errors that are often nonsensical and even counterintuitive. In this talk, I will argue for the importance of knowledge, especially commonsense knowledge, as well as inference-time reasoning algorithms, and demonstrate how smaller models developed in academia can still have an edge over larger industry-scale models, if powered with knowledge and/or reasoning algorithms.
Romania: Historiography on Holocaust and Postwar Justice Studies
Authors: Grec Emanuel-Marius
Published: September 2023

Research on the Holocaust in Romania does, as an area of research, fare so much better than other case studies in terms of interest and researchers dedicating their time to study it. In this context, a brief overview of historiography on the Holocaust in Romania must take into account a few key factors: access to archives on Holocaust-related files, evolution of the subject within larger historical narratives of Romanian history of the 20th century, trends in Holocaust research in the last few years both in Romania and abroad, as well as the dynamic between historical research and public memory in Romania. Nevertheless, and in relation to this historiographical forum, despite its relative development, one aspect related to the Holocaust in Romania has drawn significantly less scholarly attention:war crimes trials and the efforts at postwar justice.Because of this under-research, although the documentation is especially relevant in terms of archives, the following contribution focuses on the importance of the study of the postwar trials for the field after outlining the main features of the historiography on the Holocaust in Romania.
Characteristics of Malaysian 16-year-old girls who reported regular binge eating episodes and the associated risk factors: a descriptive study
Authors: Tang Yi-Ting , Liew Jia Xian , Chooi Weng-Tink
Published: September 2023

Objectives

Adolescents may suffer from binge eating (BE), that refers to consuming a large amount of food in a short period of time and accompanied by feelings of loss of control (LOC) over eating. This study compared the prevalence of BE between 16-year-old Malaysian girls from two types of public schools, Malay-English-medium and Chinese-Malay-English-medium schools. Additionally, this study identified associated risk factors of those who presented regular BE episodes, including LOC eating, anxiety, body mass index (BMI), body dissatisfaction (BD) and eating disorders (EDs) psychopathology.

Methods

398 participants completed self-reports assessing BE symptoms, LOC eating, state anxiety, trait anxiety, EDs psychopathology, and BD. They also reported heights and weights. Descriptive statistics, t-tests, chi-square tests, and Z-test for independent proportions were conducted.

Results

There was no significant difference in either the prevalence of BE or EDs psychopathology between participants from the two types of schools. 71 (17.8 %) participants reported moderate-to-severe symptoms of BE, and 46 (11.6 %) reported moderate-to-severe levels of LOC eating. Those who reported moderate-to-severe symptoms of BE reported significantly higher levels of LOC eating, BD, drive to be thinner, BMI, state anxiety, and EDs psychopathology, compared to those who reported none-to-minimal BE.

Conclusions

BE and LOC eating appeared to be relatively common among secondary school girls in Malaysia. The relatively high prevalence of BE amongst adolescents in our sample highlighted the importance of early identification of signs for BE as preventive measures from developing EDs psychopathology among children and adolescents. We propose that attitudes towards eating and body image-related concerns should be included in school screenings aimed at preventing psychological problems in minors.
The knowledge politics of genome editing in Africa

Published: September 2023

How is the promise of crop genome editing viewed by scientists working with or aspiring to work with the technology, by development experts seeking to mold public perceptions and policy attitudes toward genome editing, and by donors that provide funds for genome-editing research for agricultural applications in sub-Saharan Africa? In this article, we present data from interviews with these stakeholders to shed light on their aspirations, concerns, and expectations. Previous scholarship on genome editing in relation to African agriculture has focused on the technical capabilities of genome editing techniques and surveys of current research and development activities in this field. This article contextualizes and reflects critically on expectations that genome editing can or will deliver benefits for African scientists and farmers. The interviews reveal excitement around genome editing and anticipation for what it could achieve, but also a sober realism and frustration regarding the political-economic hurdles that constrain African scientists and research institutions and the generation of public goods for African farmers and societies. These insights, we show, challenge extant narratives related to genome editing and accessibility. As such, we center and interrogate the politics of knowledge surrounding the emergence of genome editing in Africa.
Liberal Multiculturalism versus Diversity
Authors: Joppke Christian
Published: September 2023

Karl Polanyi described the crisis of his time in terms of a “double movement,” in which the rise of the self-regulating market was counterpointed by a protectionist movement of its losers. Updating Polanyi, Nancy Fraser argued that the current crisis is better conceptualized as a “triple movement,” with “emancipation” as a “third political project,” separate from “marketization” and “social protection.” This paper examines significant variation under the emancipation umbrella. In particular, I contrast liberal multiculturalism, as canonized by Will Kymlicka, with diversity, which has taken both neoliberal and illiberal directions.
Casein kinase 1 and 2 phosphorylate Argonaute proteins to regulate miRNA‐mediated gene silencing
Authors: Shah Vivek Nilesh , Neumeier Julia , Huberdeau Miguel Quévillon , Zeitler Daniela M , Bruckmann Astrid , Meister Gunter , Simard Martin J
Published: September 2023

MicroRNAs (miRNAs) together with Argonaute (AGO) proteins form the core of the RNA‐induced silencing complex (RISC) to regulate gene expression of their target RNAs post‐transcriptionally. Argonaute proteins are subjected to intensive regulation via various post‐translational modifications that can affect their stability, silencing efficacy and specificity for targeted gene regulation. We report here that in Caenorhabditis elegans, two conserved serine/threonine kinases – casein kinase 1 alpha 1 (CK1A1) and casein kinase 2 (CK2) – regulate a highly conserved phosphorylation cluster of 4 Serine residues (S988:S998) on the miRNA‐specific AGO protein ALG‐1. We show that CK1A1 phosphorylates ALG‐1 at sites S992 and S995, while CK2 phosphorylates ALG‐1 at sites S988 and S998. Furthermore, we demonstrate that phospho‐mimicking mutants of the entire S988:S998 cluster rescue the various developmental defects observed upon depleting CK1A1 and CK2. In humans, we show that CK1A1 also acts as a priming kinase of this cluster on AGO2. Altogether, our data suggest that phosphorylation of AGO within the cluster by CK1A1 and CK2 is required for efficient miRISC‐target RNA binding and silencing.

Authors: Subramaniam Angkay , Mohd-Isa Wan-Noorshahida , Yap Timothy , Ramakrishnan Kannan
Published: September 2023

ECG signal printed on a graph paper has been widely used by medical examiners to analyze diseases related to the heart. Medical practitioners rely on historical records to perform diagnosis. Constantly accessing the ECG printed graph paper manually could be time consuming as there are bulk of graph papers for examination. The proposed work aims to convert the printed ECG graph paper into digitized ECG for remote diagnosis. The ECG printed graph paper undergoes conversion into ECG artifact before transforming as digitized ECG. In the initial phase, patient information in the ECG artifact is preserved by encoding into a QR Code. In phase two, preliminary processing is done on ECG artifact for removal of gridline in the background. Image convolution method is proposed as the process for background gridline removal. Then, morphological image processing is implemented to enhance the ECG artifact. In phase three, segmentation process takes place, in which the ECG artifact is divided into segments for separating the waveforms. In the final phase of ECG digitization, the location of the signal is traced for reshaping the ECG artifact as digitized ECG. The accuracy of the ECG digitization is measured through the heart rate that is calculated using our approach and compared with the one on ECG printed graph paper. The average sum of squared error of the heart rate between the ECG printed graph paper and digitized ECG is 0.005618. The digitized ECG can be useful for medical examiners and practitioners in telemedicine where remote diagnosis may be needed.

Examining Child Multitouch Screen Interaction Model: A Causal Effect Analysis
Authors: Liew TzeHui , Lau SiongHoe , Ismail Hishamuddin
Published: September 2023

Continual technological innovation, especially in educational technology for pre-school education, has led to a boom in new interaction characteristics in Child-Computer Interaction (CCI) research. The problem of limited screen sizes as a display and input device poses a design challenge that remains unanswered. Research with pre-school children requires careful attention to suitable methods, designs, and child-friendly models. The Child-Oriented TAM model has been adapted, and two new independent variables, namely screen size (SCS) and object size (OBS), were proposed for this study to gather feedback from children on their interaction satisfaction with multitouch screens. This study aims to validate the relationship between the variables of Perceived Usefulness (PU), Perceived Ease of Use (PEOU), screen size (SCS), object size (OBS), and Satisfaction (SATIS) in pre-school children's interaction with multitouch screens, and to test the moderating effects of age on this relationship. The findings of this study confirm that pre-school children's satisfaction with multitouch screen interaction is determined by screen size and moderated by age. Pre-school educators, parents, and researchers can now have a better understanding of how screen size may affect children's ability to interact with multitouch screens.

Published: September 2023

This paper investigates the impact of background music on students' cognitive performance in the classroom environment, aiming to enhance attention and improve learning outcomes. The study conducted an experiment with 100 design students from MMU, randomly dividing them into treatment and control groups. The treatment group listened to background music genres such as Lo-fi and modern classical remix, while the control group experienced silence. The effects of background music on cognitive performance were analyzed and compared. The comprehensive literature review highlights the potential of background music to positively influence cognitive functioning and learning outcomes in specific contexts. The study employed a mixed-method research design, combining qualitative data from online open-ended question surveys and quantitative data from Likert scale questionnaires. The experiment utilized pre- test and post-test measurements, with participants allocated to controlled and treatment groups using a random sampling technique. Positive findings emerged from the analysis, indicating significant improvements in attention, concentration, focus, motivation, memory, and mood among students exposed to background music. However, the study acknowledges limitations such as the small sample size and specific research context, calling for further studies with larger and more diverse samples to enhance generalizability. These findings emphasize the potential of background music to positively impact cognitive performance and contribute to enhancing students' learning experiences.

Published: September 2023

This paper was follow-up research of the author’s dissertation entitled, "Homicide by Wife in the Context of Domestic Violence: Case Studies of Convicted 4 Female Perpetrators in Women Prisons in Bandung, Indonesia." The findings from the dissertation showed that, in a normative manner, a wife who committed homicide against her husband was guilty and violated the criminal law regardless of the motive behinds it. Using feminist research and qualitative approach, the author argued that women (wives) who killed their partners in response to domestic violence were also victims. Therefore, imprisonment was not appropriate for them. This article discussed the public’s perception on women committing homicide in response to domestic violence by exploring the reasons why women engaged in such acts, rehabilitation measures, lenient treatment, and protection programs for women who committed homicide in reaction to domestic violence. Based on these discussions, the author concluded that a specific policy was necessary in Indonesia to regulate alternative intervention programs for women (wives) who commit homicide to their partners in reaction to domestic violence. The intervention programs shall include social work penalty and rehabilitation measures as well as implementation procedures, success indicator measurement, and evaluation criteria to see the implications of the policy.

The present study aims to identify and quantify the edible mushroom with high production value in Pinus radiata forests, and their natural production as an ecosystem service for the peasant communities of Cuyuni and Yuracmayo in the district of Ccatca (Cusco, Peru). Fifty fungal samples were collected according to cap diameter (10 cm, 15 cm and 20 cm), for counting and taxonomic identification. The samples were collected in 5 Pinus radiata forests with different growth ages (forest younger than 3 years, between 4 to 7 years and older than 7 years). The edible fungal species identified were Laccaria laccata and Suillus luteus, both in symbiotic growth with Pinus radiata, the latter being the most representative species due to its abundance and usefulness food, which gives it a high commercial value. The non-parametric Kruskal-Wallis test of SPSS software was used and determined that there is a statistical difference between different groups of the Suillus luteus and Pinus radiata forests with different growth ages. For example, it presents a higher average growth rate in Pinus radiata forests older than 7 years with an average production rate of 523.6 kg in fresh weight per harvesting season. However, there is also a homogeneity of the Suillus luteus species in all the Pinus radiata forests. Therefore, this type of fungus represents the most productive edible mushroom component for the Cuyuni and Yuracmayo communities.

Fishing is not lucrative among Omanis mainly due to lack of economic viability and Oman is roughly forgoing 2.4 billion Omani rial due to lack of active involvement of fishermen in the process of value chain of fishing despite many subsidies. If the country uses its fishing potential, it can create profitable, sustainable fishing sector that contributes significantly for economic diversification and employment generation.  Developing a valid and reliable scale to measure fishermen's attitudes towards the fishery sector is an essential step in understanding the factors that influence their perceptions and behaviors. A well-designed scale can help those involved in fisheries decision making and researchers identify areas for improvement and develop targeted interventions to address issues in the fishery sector. Overall, the development of this questionnaire has provided a comprehensive understanding of the challenges facing fishermen and the prospects for the fisheries sector. The results suggest that the adoption of appropriate measures, such as improving access to finance, investing in new technologies, and strengthening government policies, can improve the livelihoods of fishermen and promote sustainable growth in the fisheries sector.

This study aims to examine the influence of Augmented Reality (AR) on Cooperative Learning (CL) and Students' Achievement (SA) within the context of education. This study employed a survey-based research design to investigate the proposed connections between constructs, using a two-step methodology to empirically examine the hypothesized relationships. The data collection process involved the creation of a meticulously designed, structured questionnaire, specifically targeting students at the Institute of Public Administration in KSA. A pilot test was conducted with the assistance of three experienced instructors, and a remarkable response rate of 67% was achieved with 81 completed questionnaires, of which 67 were deemed usable for analysis. To test the hypothesized associations, the cutting-edge partial least squares (PLS) modeling approach was employed, ensuring accurate and reliable results. The learning process begins with teachers explaining the new learning process and students being grouped based on cooperative learning strategies. Students will be asked to install the ARLOOPA application on their mobile devices and given printed cards to scan with their mobile devices. The findings provide compelling evidence supporting the hypotheses, indicating that the use of AR has a positive effect on both CL and SA. Furthermore, the study confirms the reciprocal relationship between CL and SA, suggesting that CL implementation fosters improved student achievement. Overall, this study contributes to the existing literature and provides valuable insights into the application of AR to enhance cooperative learning and student achievement.

Recently, social networking services have surged in popularity, significantly elevating the influence of influencers engaged in SNS activities. This study investigated the correlation between several variables including influencer attributes, the quality of the relationship between influencer and customer, influencers' intentions to purchase products, and loyalty to them. It was observed that multiple factors considerably impacted these relationships. Nonetheless, establishing a commitment in the relationships between influencers and customers proved to be challenging, often resembling one-to-many connections rather than more intimate one-to-one engagements. Moreover, fostering stability within these relationships was deemed essential. These insights can assist companies in honing their influencer marketing strategies and in developing robust relationship-building approaches.
Comparison of Accelerated Life Tests for Two Different Systems Generated Using the Arrhenius Model
Authors: Shim Kyubark
Published: September 2023

Accelerated testing consists of a variety of methods aimed at shortening the life of a product or hastening its performance degradation in a short period of time. The purpose of these tests is to quickly obtain data that, when properly modeled and analyzed, can provide the desired information about a product’s lifetime or performance under normal use. Accelerated life testing will subject a product to conditions that exceed normal service parameters in order to uncover defects and potential failure modes. Since the guidelines for statistical analysis of thermal life test data in accelerated life tests (ANSI/IEEE Std. 101-1987) were enacted, they have been used to analyze the results of many experiments. However, Shim (2004) only used a small amount of data obtained from a limited environment for analysis of ANSI/IEEE Std. 101-1987 results, so simulations were conducted using previous research results to supplement the accuracy of the analysis. In this paper, two different systems or materials generated using the Arrhenius equation are compared in an accelerated life test to estimate the correct lifetime.

Subject and Purpose. Accuracy of the material recognition using radio wave methods in the ultra-high frequency band for substanc- es with dielectric properties is the present paper concern. To estimate a total error arising in material measurements by the radio wave method and determine constituents of the error is the aim of the work. Methods and Methodology. The material recognition accuracy is estimated by the method of statistical analysis in terms of average statistical deviation and dispersion. Results. Advantages and disadvantages of the waveguide method in which a test material sample is placed inside a metal waveguide have been traced, suggesting an obvious drawback that the material recognition process of the sort is difficult to be automated. In the remote inspection procedure, the test material is in free space (e.g. on a conveyor) where it is illuminated with a microwave transmitting antenna. The receiving antenna is located on the other side of the test sample and transfers the received signal to the apparatus for determining material parameters. There, the attenuation coefficient is measured as the electromagnetic wave passes through the sample. The measurement results show a correlation dependence of the wave attenuation coefficient on the quality of the substance, enabling us to use frequency dependences of the material to reveal its unknown quality. The remote method makes it possible to automate the recognition of materials with dielectric properties. For these methods mentioned right above, random error values arising during the material recognition were estimated by the method of statistical analysis. Conclusions. The analysis of errors in the material recognition shows that the total error ranges from 7.28 to 12.74% with corresponding constituent errors including faults of today’s microwave measuring devices, inappropriate application of the method or unsuitable type of the structural model of the parameter determination, and errors in data calculations.
