Published: October 2023

AbstractThis study investigates the outcomes of online Service-Learning (SL) in Philippine partner communities, addressing a literature gap on predominantly face-to-face (f2f) SL. Applying the Conceptual Framework of Community Impacts Arising from Service-Learning, it employs a mixed-method convergent design to assess the benefits, drawbacks, and influential factors of online SL’s effectiveness (CARE, TIP, and FEAR). Data, sourced from 101 survey participants across 46 Community Partner Organizations (CPOs) in affiliation with Ateneo de Manila University, is complemented by the insights derived from 22 comprehensive interviews with key community contact persons. Findings reveal that online SL bolsters CPOs’ missions, enhance resources, facilitates knowledge transfer, and yields positive outcomes. However, barriers such as Time management challenges, Infrastructure and technical hurdles, and Participation obstacles (TIP), along with its consequent drawbacks such as difficulty in providing timely and effective Feedback, disparity in varying levels of Effort displayed by students, erosion of Authentic relationships in prolonged virtual engagements, and Repetitiveness and nonfulfillment concerns (FEAR) were identified as challenges. Despite these, Collaborative coordination, Active communication, Responsiveness to CPO’s needs, and Engaging online environment (CARE) were recognized as key enablers. This research highlights the significance of examining the outcomes of online SL from the perspective of community partners, informing best practices for implementation, and cultivating effective online SL collaborations that can be adapted across various countries with similar contexts.

Published: October 2023

AbstractIn recent years, the global demand for high-resolution videos and the emergence of new multimedia applications have created the need for a new video coding standard. Therefore, in July 2020, the versatile video coding (VVC) standard was released, providing up to 50% bit-rate savings for the same video quality compared to its predecessor high-efficiency video coding (HEVC). However, these bit-rate savings come at the cost of high computational complexity, particularly for live applications and on resource-constrained embedded devices. This paper evaluates two optimized VVC software decoders, named OpenVVC and Versatile Video deCoder (VVdeC), designed for low resources platforms. These decoders exploit optimization techniques such as data-level parallelism using single instruction multiple data (SIMD) instructions and functional-level parallelism using frame, tile, and slice-based parallelisms. Furthermore, a comparison of decoding runtime, energy, and memory consumption between the two decoders is presented while targeting two different resource-constraint embedded devices. The results showed that both decoders achieve real-time decoding of full high-definition (FHD) resolution on the first platform using 8 cores and high-definition (HD) real-time decoding for the second platform using only 4 cores with comparable results in terms of the average energy consumed: around 26 J and 15 J for the 8 cores and 4 cores platforms, respectively. Furthermore, OpenVVC showed better results regarding memory usage with a lower average maximum memory consumed during runtime than VVdeC.

Published: October 2023

AbstractWe examine effects of parental divorce on epigenetic aging in later adulthood for two birth cohorts: one born in the early 20th century and the other born in the later 20th century. Using data from the Health and Retirement Study (n = 1,545), we examine the relationship between parental divorce in childhood and accelerated epigenetic aging in older adulthood as indicated by the Dunedin methylation Pace of Aging score. We assess how this relationship is mediated by chronic depressive symptoms, education, lifetime smoking, body mass index (BMI), and an older adult’s own divorce. The mean age of the earlier cohort is 85.8 (SD = 3.9) and that of the later cohort is 60.2 (SD = 2.8). We find that parental divorce was related to faster aging in the later-born cohort, and that 56% of this relationship (b = 0.060) was mediated by chronic depressive symptoms (b = 0.013), lower education levels (b = 0.005), and smoking (b = 0.019). For the earlier cohort, there was no effect of parental divorce on epigenetic aging. Parental divorce in childhood may have lasting effects on later-life health, as reflected in the rate of epigenetic aging. However, the effects and mechanisms of this relationship differ across cohorts living in different social environments.
Is there a blast radius of workplace bullying? Ripple effects on witnesses and non-witnesses
Authors: Rosander Michael , Nielsen Morten Birkeland 
Published: October 2023

AbstractSubstantial evidence points to detrimental effects of workplace bullying on the health, well-being and job attitudes among those exposed. What is less known is how bullying affects their non-exposed colleagues. In this study, we introduce the concept “blast radius of bullying” and use social information processing theory to investigate how bullying impacts targets, witnesses, and non-witnesses. We suggest three mechanisms to understand the impact bullying may have on non-targets: the working environment mechanism, secondary victimization, and emotional contagion. We hypothesized that non-exposed colleagues in groups where bullying exists would feel some impact of bullying, but that it would be smaller for those further away from the point of impact. We also investigated the association between the severity of mistreatment and outcomes for the above-mentioned categories. We used data (n = 2215) from 195 work groups. The results provided evidence for a blast radius of bullying, however, not as far-reaching as hypothesized as only direct observation of mistreatment was associated with negative outcomes. The severity of mistreatment was not associated with the outcomes, whereas the frequency of observation had some impact for witnesses. The study showed that also witnesses may be regarded as “co-victims”.

AbstractOptical thermometry based on the upconversion (UC) luminescence intensity ratio (LIR) has attracted considerable attention because of its feasibility for achievement of accurate non-contact temperature measurement. Compared with traditional UC phosphors, optical thermometry based on UC single crystals can achieve faster response and higher sensitivity due to the stability and high thermal conductivity of the single crystals. In this study, a high-quality 5 at% Yb3+ and 1 at% Ho3+ co-doped Gd0.74Y0.2TaO4 single crystal was grown by the Czochralski (Cz) method, and the structure of the as-grown crystal was characterized. Importantly, the UC luminescent properties and optical thermometry behaviors of this crystal were revealed. Under 980 nm wavelength excitation, green and red UC luminescence lines at 550 and 650 nm and corresponding to the 5F4/5S2 → 5I8 and 5F5 → 5I8 transitions of Ho3+, respectively, were observed. The green and red UC emissions involved a two-photon mechanism, as evidenced by the analysis of power-dependent UC emission spectra. The temperature-dependent UC emission spectra were measured in the temperature range of 330–660 K to assess the optical temperature sensing behavior. At 660 K, the maximum relative sensing sensitivity (Sr) was determined to be 0.0037 K−1. These results highlight the significant potential of Yb,Ho:GYTO single crystal for optical temperature sensors.

AbstractDifferentiating between ECG patterns related to athletes' heart remodeling and pathological findings is a challenge in sports cardiology. As the significance of fragmented complex in athletes remains uncertain, this study aimed to assess the presence of fragmented QRS in lead V1 (fQRSV1) among young athletes and its association with heart adaptations and arrhythmias. Young athletes referred for annual pre-participation screening receiving a maximal exercise testing and transthoracic echocardiography from January 2015 to March 2021 were included. The study included 684 young athletes. The prevalence of fQRSV1 was 33%. Subjects with fQRSV1 had higher exercise capacity and indexes of right ventricular function and remodeling. Among highly trained athletes, the fQRSV1 group demonstrated also increased left ventricular wall thickness. No significant association existed between fQRSV1 and exercise-induced arrhythmias, even in highly trained athletes. The high prevalence of fQRSV1 in young athletes is associated with training-induced heart adaptations but not exercise-induced ventricular arrhythmias.

Published: October 2023

AbstractDistributed ledger technologies (DLTs) are considered one of the foremost emerging technologies which can contribute to transform cities to smarter cities. DLT play important role in municipalities to accelerate the digitalization process toward changing the roles and services of enterprises in sustainable smart cities. Standardization of DLTs aids to reduce data and digital assets silos while decreasing vendor lock-in across distributed applications enabling a digital urban ecosystem that supports migration capabilities making it possible for cities to seamlessly achieve interoperability among DLTs and centralized digital platforms, although a few standards such as IEEE 2418, IEEE P2418.5, and ISO/TC 307 have been developed. The alignment and integration mechanisms required to support standardization of DLT for interoperable services in smart cities is lacking. Therefore, this study presents an understanding on current and open issues on standardization of DLTs in sustainable smart cities with a specific focus on data integration and alignment efforts related to interoperable DLTs. A framework is developed to promote standardization of DLTs to support integration and alignment for interoperability in smart cities. Design science research methodology was adopted based on three use case scenarios which illustrates how IOTA tangle is employs as a DLT for secured standardized communication between physical sensors, devices, and digital platforms in smart city environment. Findings from this article provide exploratory evidence demonstrating the potential uses of IOTA tangle through the developed framework applied for decentralized and centralized digital services. Based on this evidence, this study provides interface integration and alignment strategies to better exploit distributed applications full potential by improving DLT standardization in urban environment.
Life Satisfaction and Affect: Why Do these SWB Measures Correlate Differently with Material Goods and Freedom?
Authors: de Boer Jelle 
Published: October 2023

AbstractTwo different types of subjective well-being (SWB) measures exhibit a remarkable difference in their correlations with people’s circumstances. The life satisfaction method shows relatively a strong correlation with income and material conveniences while affective measures are more tightly linked with freedom. Why is this so? To explain this difference I examine the cognitive mechanisms underlying these measures by means of dual process theory. This theory identifies two broad categories of cognition. One is Type 1: fast, intuitive, automatic and autonomous. The other is Type 2: slow, deliberate and under conscious control. (They are also known as System 1 and System 2). I argue that in our normal decision making there is a division of labor between these mechanisms. Type 2 is more focused on making choices, comparing material goods and tradeoffs between them, while Type 1 is more oriented at the freedom that is necessary to make those choices.

AbstractBlood vessels are essential for nutrient and oxygen delivery and waste removal. Scaffold-repairing materials with functional vascular networks are widely used in bone tissue engineering. Additive manufacturing is a manufacturing technology that creates three-dimensional solids by stacking substances layer by layer, mainly including but not limited to 3D printing, but also 4D printing, 5D printing and 6D printing. It can be effectively combined with vascularization to meet the needs of vascularized tissue scaffolds by precisely tuning the mechanical structure and biological properties of smart vascular scaffolds. Herein, the development of neovascularization to vascularization to bone tissue engineering is systematically discussed in terms of the importance of vascularization to the tissue. Additionally, the research progress and future prospects of vascularized 3D printed scaffold materials are highlighted and presented in four categories: functional vascularized 3D printed scaffolds, cell-based vascularized 3D printed scaffolds, vascularized 3D printed scaffolds loaded with specific carriers and bionic vascularized 3D printed scaffolds. Finally, a brief review of vascularized additive manufacturing-tissue scaffolds in related tissues such as the vascular tissue engineering, cardiovascular system, skeletal muscle, soft tissue and a discussion of the challenges and development efforts leading to significant advances in intelligent vascularized tissue regeneration is presented.
A survey on IoT & embedded device firmware security: architecture, extraction techniques, and vulnerability analysis frameworks

Published: October 2023

AbstractIoT and Embedded devices grow at an exponential rate, however, without adequate security mechanisms in place. One of the key challenges in the cyber world is the security of these devices. One of the main reasons that these devices are active targets for large-scale cyber-attacks is a lack of security standards and thorough testing by manufacturers. Manufacturer-specific operating systems or firmware of various architectures and characteristics are typically included with these devices. However, due to a lack of security testing and/or late patching, the underlying firmware or operating systems are vulnerable to numerous types of vulnerabilities. Reverse engineering and in-depth research of the firmware is required to detect the vulnerabilities. In this paper, we've delved into various aspects of IoT and embedded devices. This includes a comprehensive survey on the architecture of firmware, techniques for firmware extraction, and state-of-the-art vulnerability analysis frameworks for the detection of vulnerabilities using various approaches like static, dynamic, and hybrid approaches. Furthermore, we’ve scrutinized the challenges of existing vulnerability analysis frameworks and proposed a novel framework to address these issues.
The new judicial federalism: the evolving relationship between EU and Member State courts
Authors: Zglinski Jan 
Published: October 2023

AbstractA wind of change is blowing through the European judicial landscape. During the past decade, the European Union (EU) judiciary has undergone its biggest institutional overhaul in generations, the rise of authoritarian populism in Central and Eastern Europe has prompted a Rule of Law crisis, several supreme and constitutional courts challenged the supremacy of EU law, while the Court of Justice re-articulated the scope of the duty to refer under Article 267 TFEU and, for the first time, found that domestic last-instance courts breaching it triggered state liability. This Article argues that these and similar developments, once looked at together, suggest that something fundamental has shifted in the EU’s judicial architecture. A new form of judicial federalism has emerged, which departs from the traditional way in which relations between EU and Member State courts used to be structured. Although this new federalism is multifaceted and is marked by both centripetal and centrifugal forces, its distinguishing feature is a stronger centralisation, which manifests itself in a considerably expanded federal judiciary, a greater emphasis on hierarchy, a more careful use of European judicial resources, as well as tighter supervision of national procedures and court structures.
The Freedom of Solar Systems
Authors: Koschel Mathis 
Published: October 2023

AbstractThis essay discusses how, for Hegel, freedom can be realized in nature in a rudimentary fashion in solar systems. This solves a problem in Kant's account of freedom, namely, the problem that Kant only gives anegativeargument for why freedom isnotimpossible but does not give apositiveaccount of how freedomisreal. I give a novel account of Kant's negative argument. Then, I show how, according to Hegel, solar systems can be considered as exhibiting freedom in a rudimentary fashion. Finally, I lay out how Hegel systematically develops this point about the freedom of solar systems in the ‘Mechanism’ chapter of theScience of Logic. In doing so, he uses Kant's negative argument in a ‘purified’ form to arrive at an account of an ‘intimate token-type relation’ between the planets in a solar system and the law that governs their motion. The essay as a whole provides a concrete example of how Hegel is an inheritor and radicalizer of Kant, both with respect to freedom's reality and with respect to philosophical method.
Against Quantitative Primitivism
Authors: Perry Zee R. 
Published: October 2023

AbstractThe problem of quantity is the problem of identifying what about the physical world explains why it can be so well represented with mathematical entities. I introduce “quantitative primitivism,” the dominant position in the literature, which offers only a partial solution to the problem of quantity. I argue that a reductive account of quantitativeness provides a full solution to the problem and describe two reductive accounts in the literature. I discuss some of the unique metaphysical consequences of reductive accounts of quantity, including a novel dissolution to the long-standing absolutist–comparativist debate.

AbstractSpeleothem fluorescence can provide insights into past vegetation dynamics and stalagmite chronology. However, its origin and especially the formation of fluorescent laminations in stalagmites are poorly understood. We conducted a year-long monthly monitoring of drip water fluorescence in La Vallina Cave (northern Iberian Peninsula) and compared the results to drip water chemistry and active speleothems from the same sites. Drip waters were analyzed using fluorescence spectroscopy and parallel factor analysis (PARAFAC). The resulting five-component model indicates contributions from vegetation, microbial activity, and bedrock. Intra-site fluorescence variability is mainly influenced by changes in overlying vegetation, water reservoir time, and respiration rates. Contrary to prevailing views, we find no systematic increase in drip water fluorescence during rainy conditions across drip sites and seasonal variations in drip water fluorescence are absent at a location where present-day speleothem layers form. Our findings challenge the notion of a higher abundance of humic-like fluorescence during the rainy season as the primary cause for layer formation and suggest additional controls on drip water fluorescence, such as bedrock interaction and microbial reprocessing. We also propose that growth rate may control the dilation of the fluorescence signal in stalagmites, indicating other potential mechanisms for fluorescent layer formation.
BONE POINTS IN TIME: DATING HUNTER-GATHERER BONE POINTS IN THE TERRITORY OF LITHUANIA

Published: October 2023

ABSTRACTBone points were one of the major hunting implements in northern European hunter-gatherer societies. They differ in shapes, types, and manufacturing techniques. In this paper, we investigate 22 bone points from the territory of Lithuania, by studying their morpho-technological characteristics, direct dates, and adhesive residues. The majority are isolated finds, but four points were selected from excavated archaeological sites dated between the 5th and 3rd millennia cal BC. Most of the points belong to the barbed points category, but six slotted points were also studied. Of the 22, 16 previously undated points were sampled for accelerator mass spectrometry radiocarbon (AMS 14C) dating. The results of 10 successfully dated samples are discussed together with previously published 14C dates of bone points from the same region. ATR-FTIR analysis of adhesive residues from six points suggest that birch bark tar was used to haft barbed points and lithic inserts. The results reveal the diversity of types of Early Holocene bone points in the territory of Lithuania, while the slotted and Kunda-type bone points fall into narrow timeframes.
