HPCache: memory-efficient OLAP through proportional caching revisited
Authors: Nicholson Hamish , Chrysogelos Periklis , Ailamaki Anastasia 
Published: December 2023

AbstractAnalytical engines rely on in-memory data caching to avoid storage accesses and provide timely responses by keeping the most frequently accessed data in memory. Purely frequency- and time-based caching decisions, however, are a proxy of the expected query execution speedup only when storage accesses are significantly slower than in-memory query processing. On the other hand, fast storage offers loading times that approach fully in-memory query response times, rendering purely frequency-based statistics incapable of capturing the impact of a caching decision on query execution. For example, caching the input of a frequent query that spends most of its time processing joins is less beneficial than caching a page for a slightly less frequent but scan-heavy query. Thus, existing caching policies waste valuable memory space to cache input data that offer little-to-no acceleration for analytics. This paper proposes HPCache, a buffer management policy that enables fast analytics on high-bandwidth storage by efficiently using the available in-memory space. HPCache caches data based on the speedup potential instead of relying on frequency-based statistics. We show that, with fast storage, the benefit of in-memory caching varies significantly across queries; therefore, we quantify the efficiency of caching decisions and formulate an optimization problem. We implement HPCache in Proteus and show that (i) estimating speedup potential improves memory space utilization, and (ii) simple runtime statistics suffice to infer speedup. We show that HPCache achieves up to a 1.75x speed-up over frequency-based caching policies by caching column proportions and automatically tuning them. Overall, HPCache enables efficient use of the in-memory space for input caching in the presence of fast storage, without requiring workload predictions.
Coping with expectation violations in education: the role of optimism bias and need for cognitive closure
Authors: Henss Larissa , Pinquart Martin 
Published: December 2023

AbstractAlthough most individuals experience expectation violations in their educational years, individuals’ coping strategies differ depending on situational and dispositional characteristics with potentially decisive influence on educational outcomes. As a situational characteristic, optimism bias indicates that individuals tend to update their expectations after unexpected positive feedback and to maintain their expectations after unexpected negative feedback. As a dispositional characteristic, a higher need for cognitive closure (NCC) indicates that individuals tend to both update (accommodation) and try to confirm expectations (assimilation) after unexpected negative feedback. To better understand mechanisms behind optimism bias and context-dependent effects of NCC in an educational context, we included controllability (attribution of success/failure to internal or external causes) and self-enhancement (amplifying positive self-relevant aspects) in an experimental case vignettes study. Our sample of n = 249 students was divided into four experimental groups (high/low controllability × positive/negative valence) and read four different case vignettes referring to expectation violations in an educational context. MANCOVA revealed that individuals updated their expectations after unexpected positive feedback only with stronger (vs. weaker) self-enhancement and that individuals maintained their expectations after unexpected negative feedback in controllable (vs. uncontrollable) situations. Furthermore, interindividual differences in NCC interacted with controllability in predicting expectation update. We conclude that considering the influences of controllability and self-enhancement, we can better understand and evaluate the adaptivity of the optimism bias and context-dependent effects of NCC in an educational context.
Government spending efficiency in Latin America
Authors: Afonso António , Fraga Gabriela Baquero 
Published: December 2023

AbstractWe assess public spending efficiency of 20 Latin American countries over the period of 2000–2019, computing data envelopment analysis efficiency scores. For the Public Sector Performance composite indicator, we use the annual data of socio-economic indicators, and for the input measure we consider Total Public Spending as a percentage of GDP, by spending category. The results show that public spending during the period under study increased, but that overall governments were not efficient, as on average they could have used 27% less spending to achieve the same levels of performance. On the other hand, governments could have increased their performance by 18% whilst maintaining the same level of spending. The most-efficient countries were Chile, Guatemala, Panama, and Paraguay, with the least efficient being Bolivia, Venezuela, Nicaragua, Suriname, and Brazil.
The Impact of Anti-Sexual Harassment Policies on Sexual Harassment Prevention in the Workplace
Authors: Blumell Lindsey E. , Mulupi Dinfin 
Published: December 2023

Abstract
Despite increasing pressure to implement anti-sexual harassment policies, the issue remains largely unresolved within organizations in many countries. This mixed-methods study used a survey of 575 news professionals and an analysis of 17 anti-sexual harassment policies in Botswana, Kenya, Malawi, Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe to understand the effectiveness of anti-sexual harassment policies in preventing and correcting sexual harassment in the workplace. Results show no significant differences of experienced or reported sexual harassment between organizations with or without a policy. Only 30% of participants reported their experiences with organizations responding to 42% of reported cases. The only measured significant impact of policies was found with participants who had been trained on the policy and the likelihood for their organization to act. An analysis of the policies showed they contained unclear definitions, reporting mechanisms, complaint processes, organizational communication, and monitoring. In discussing these results, we highlight how gendered norms must be considered to implement more effective anti-sexual harassment policies.
Higher education and the flipped classroom approach: efficacy for students with a history of learning disabilities

Published: December 2023

AbstractHigher education continually seeks new approaches to support students with various learning needs. At present, Finland attempts to provide such support through accessibility and reasonable accommodation efforts, but students with learning disabilities may still encounter many barriers in their studies. One approach suggested to meet the needs of a diverse student population is the flipped classroom. While substantial research exists about its benefits and drawbacks, less is known from the perspective of students who have a history of receiving pedagogical support. Therefore, the present study examined the experience and performance of these students in flipped higher education courses. Results indicated no difference in the academic performance of learners with a history of support compared to those without. Students with a history of support needs reported a lower assessment of self-regulation and self-efficacy for learning, and experienced the flipped courses as more difficult. However, they favored more collaboration in general and in the flipped classroom approach in particular. Additionally, regression models indicated that achievement in flipped courses was explained primarily from the lack of regulation and guidance perspectives. These findings suggest new insights for teaching those with learning disabilities, particularly the support a flipped classroom may provide, but developing a more in-depth understanding is warranted.

Published: December 2023

AbstractWe assessed changes in the sociodemographic structure, land use, diet, and nutritional status of the population of a rural village in West Java, Indonesia between 2000–2001 and 2015–2017, a period of rapid socioeconomic change in the country. Over this period, the village’s population increased by 50%, largely comprised of individuals engaged in non-agricultural employment in the village or in nearby cities, and the village maintained its farming characteristics without major changes in the local land use or ecosystem. In 2000, the diet, nutritional intake, and health status of the villagers were generally uniform. Indicators based on BMI, for example, classified 98% of target children and 70% of target mothers as ‘normal’, regardless of household economic status. However, by 2015, more people worked outside the village and dependence on a market economy had increased. Dependence on food from outside the village, such as processed foods that are cheap and easy to obtain and store, had also increased. Foods such as cassava, taro, and sweet potatoes, which were grown and consumed in 2000, were not consumed in 2015. The quantities of beans, nuts, and vegetables consumed had also decreased. Additionally, the use and sharing of natural resources and the accompanying knowledge transfer had been gradually lost. As a result, variation in diet, nutritional intake, and health conditions within the village significantly increased over time, and overnutrition and undernutrition coexisted by 2015.
Novel alginate-based binders for silicon–graphite anodes in lithium-ion batteries: effect of binder chemistry on the electrochemical performance

Published: December 2023

AbstractNovel alginate-based binders containing either catechol (d-Alg) or sulfonate (s-Alg) functional groups were developed and characterized to improve the capacity decay performance and better stability of Li-ion batteries. The electrochemical performance of silicon–graphite (Si/Gr) anode with alginate-based binders were compared to the commonly used CMC/SBR binder. The active material in the anodes was the ball-milled Si/Gr (20:80 wt%) powder mixture. A comprehensive electrochemical study was carried out through rate capability test, cycle test, differential capacity analysis (dQ/dV), and electrochemical impedance spectroscopy (EIS). The functionalized s-Alg binder showed the lowest electrolyte uptake (11.5%) and the highest tensile strength (97 MPa). Anodes with s-Alg exhibited high initial capacity (1250 mAh g−1) and improved decay performance (580 mAh g−1 at 0.2 C), by ~ 65% higher compared to CMC/SBR binder. The influence of pH value of s-Alg binder preparation showed that anodes prepared at pH 3 of s-Alg exhibit better performance, reaching 800 and 750 mAh g−1 at 0.1 and 0.2 C, respectively, due to the stronger bonding formation and compactness of anode layer which providing low charge transfer and solid electrolyte interface resistance.

Published: December 2023

Abstract
Purpose
Hyaluronidase-facilitated subcutaneous immunoglobulin (fSCIG) 20% will allow reduced infusion volumes and frequency versus existing subcutaneous therapies such as fSCIG 10% and conventional subcutaneous immunoglobulin 20%, respectively. We assessed the tolerability, safety, and immunogenicity of warmed and unwarmed fSCIG 20%.

Methods
This phase 1, single-dose, open-label, three-arm study enrolled healthy adults aged 19–50 years (inclusive) at a single US center (NCT05059977). Post-screening, participants received a single fSCIG 20% dose comprising recombinant human hyaluronidase and varying doses of in-line warmed or unwarmed immunoglobulin G (IgG) during a 4-day treatment period in a sentinel and sequential dosing design (treatment arm 1, warmed IgG 20% 0.4 g/kg; treatment arm 2, warmed IgG 20% 1.0 g/kg; treatment arm 3, unwarmed IgG 20% 1.0 g/kg). Participants were followed for 12 (± 1) weeks post-infusion. The primary endpoint was tolerability (“tolerable” infusions were not interrupted, stopped, or reduced in rate owing to fSCIG 20%-related treatment-emergent adverse events (TEAEs)). Secondary endpoints included occurrence of TEAEs.

Results
Overall, 24 participants were included, 8 per treatment arm (mean age 39.0 years, 54.2% men). All participants tolerated the infusions. All TEAEs were mild (107 events, in all participants), and all participants experienced fSCIG 20%-related (105 events) and local (102 events) TEAEs. Infusion site erythema and infusion site swelling were most frequently reported. No serious TEAEs occurred, and no participants discontinued the study owing to TEAEs.

Conclusion
fSCIG 20% was well-tolerated with a favorable safety profile in healthy adults. Future studies will evaluate fSCIG 20% in primary immunodeficiency diseases.

Challenge or Threat? The Effects of the Standard and a Second-Generation Mindfulness Intervention with Buddhist Practices on Cognitive Appraisals of Stress: Secondary Analysis of a Randomized Controlled Experiment Performed in Switzerland
Authors: Gamaiunova Liudmila , Brandt Pierre-Yves , Kliegel Matthias 
Published: December 2023

AbstractContemplative approaches rooted in Buddhist traditions have been linked to the attenuation of response to social stress. Anticipatory cognitive appraisals of social situations potentially represent a mechanism explaining the stress-reducing effects of contemplative practices. The cognitive appraisal of threat is associated with an anticipated loss of social self-esteem. In contrast, the cognitive appraisal of challenge involves recognizing the potential for gain or growth in stressful situations and is associated with a more adaptive cardiovascular response. In this secondary analysis of a randomized controlled experiment performed in Switzerland, we evaluated the effects of two contemplative interventions on cognitive appraisals of challenge and threat and associated physiological profiles. The interventions were a standard Mindfulness-Based Stress Reduction (MBSR) program and a new program (MBSR-B), which included several elements from Buddhist practices. After an eight-week intervention, participants completed the Trier Social Stress Test (TSST) and underwent the assessment of primary cognitive appraisals and cardiovascular response to stress. The results demonstrated greater challenge appraisal in the MBSR (n = 20) and MBSR-B (n = 21) groups compared to Control (n = 24), and MBSR-B participants scored higher on the challenge than threat appraisal. At the physiological level, the groups did not differ on changes in cardiac output and total peripheral resistance. Still, an exploratory analysis demonstrated that the MBSR-B group’s cardiovascular profile best resembled challenge appraisal. The results suggest that contemplative approaches foster challenge appraisal, contributing to a more adaptive response to stress.
Earthquake swarms near the Mór Graben, Pannonian Basin (Hungary): implication for neotectonics

Published: December 2023

AbstractThe central part of the Pannonian Basin is characterised by low to medium seismicity. North central Hungary is one of the most dangerous areas of the country in terms of earthquakes, which also includes the area of the Mór Graben where some of the largest earthquakes occurred in Hungary’s history. Recent activity has been observed in the Mór Graben. It has been established that earthquake swarms occur quite frequently in the graben. To further study these events, we deployed a temporary seismic network that operated for 20 months. Using the temporary network stations as well as permanent stations from the Kövesligethy Radó Seismological Observatory and the GeoRisk Ltd. networks we registered 102 events of small magnitudes. In this paper, we demonstrate and compare three different event detection methods based on the registered waveforms by the permanent and temporary stations to find the optimal one to collect a complete swarm list in the Mór Graben. After the hierarchical cluster analysis, we relocated the hypocentres using a multiple-event algorithm. Our results demonstrate that the most successful detector in this case is the “Subspace detector.” We managed to create a complete list of the events. Our results indicate that the Mór Graben is still seismically active.
How to do things with insecure extensions
Authors: Lauer Helen 
Published: December 2023

AbstractThe multi-purpose of publicizing a scientific consensus includes a communicative strategy by which scientific institutions accommodate the weighty social and economic demands to demonstrate they are collaborating and cooperating with non-scientific sectors of society, relying on a wide range of spokespeople and representatives to carry out the delivery of their consensus in formal, institutionally arranged, professional and impersonal public settings. I investigate the conditions and presuppositions that make it possible for a research consortium to contribute indirectly to public discourse beyond the presentation of empirical data and theoretical speculations routinely associated with knowledge-producing collectives. The baptismal action of researchers in selecting a designative name to announce a new discovery of virus species and species variants does not follow the rigorous regulations that standardize all names of taxonomic categories in other biological sciences as well as higher order taxa in virology. It is argued here that the lack of clarity in the denotation of the term ‘Ebola’ (in epidemiological reports from West Africa throughout 2014–2016) serves the purpose of shifting a receptor’s understanding of a statement from its explicit assertive point to an implicit declarative, commissive, directive or expressive, covertly delivered point. Specialists of nomenclature concerned with quality assurance regard this lapse in standardization as a consequence of human fallibility demanding urgent intervention. Here it is proposed instead that the occlusive effect of a technical descriptive name may serve an important communicative function.
Body condition scoring in alpacas (Vicugna pacos) and llamas (Lama glama) – a scoping review
Authors: Wagener Matthias Gerhard , Ganter Martin , Leonhard-Marek Sabine 
Published: December 2023

AbstractAssessment of the body condition score (BCS) is an important tool to check the nutritional status of an animal, and thus can provide important information in herd management, but also in the veterinary examination of individual animals. In dairy farming, BCS has been recognized as an important parameter for a long time already, but over the years body condition scoring has also become more important for other species. Especially in South American camelids (SACs: alpacas and llamas), whose dense coat can hide a poor nutritional status for a long time, regular assessment of the BCS is recommended by different authors and organizations. To date, there are several instructions for the assessment of the BCS in SACs, which, however, differ significantly in some points. For a consistent approach, a total of 35 instructions for the BCS in SACs were compared in a scoping review. The spine, especially the lumbar vertebrae as well as the ribs were identified as the two main body sites recommended for assessing the BCS. Furthermore, the area between the front and rear leg and the pelvis were mentioned frequently; however, these body sites were discussed controversially. The paralumbar fossa, shoulder, and udder were only mentioned sporadically. Among the various scales, the 1–5 scale was mentioned most frequently, with the optimal BCS being 3. Nonetheless, physiological fluctuation due to breed, age, sex, pregnancy, and lactation have to be considered. The BCS should be assessed each time the animals are handled, but at least monthly. In contrast to body weight, the BCS reflects the nutritional status of an animal even after a single examination. The review showed that much of the available information on the assessment of BCS in SACs is based on practical experience rather than scientific evidence. Indeed, some of the assumptions made there might still have to be verified or modified.

Published: December 2023

Abstract
Purpose of Review
To discuss the history of cardiovascular outcomes trials of cholesteryl ester transfer protein (CETP) inhibitors and to describe obicetrapib, a next-generation, oral, once-daily, low-dose CETP inhibitor in late-stage development for dyslipidemia and atherosclerotic cardiovascular disease (ASCVD).

Recent Findings
Phase 1 and 2 trials have evaluated the safety and lipid/lipoprotein effects of obicetrapib as monotherapy, in conjunction with statins, on top of high-intensity statins (HIS), and with ezetimibe on top of HIS. In ROSE2, 10 mg obicetrapib monotherapy and combined with 10 mg ezetimibe, each on top of HIS, significantly reduced low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), apolipoprotein B, total LDL particles, small LDL particles, small, dense LDL-C, and lipoprotein (a), and increased HDL-C. Phase 3 pivotal registration trials including a cardiovascular outcomes trial are underway.

Summary
Obicetrapib has an excellent safety and tolerability profile and robustly lowers atherogenic lipoproteins and raises HDL-C. As such, obicetrapib may be a promising agent for the treatment of ASCVD.
Cybersecurity discussions in Stack Overflow: a developer-centred analysis of engagement and self-disclosure behaviour
Authors: Díaz Ferreyra Nicolás E. , Vidoni Melina , Heisel Maritta , Scandariato Riccardo 
Published: December 2023

Abstract
Stack Overflow (SO) is a popular platform among developers seeking advice on various software-related topics, including privacy and security. As for many knowledge-sharing websites, the value of SO depends largely on users’ engagement, namely their willingness to answer, comment or post technical questions. Still, many of these questions (including cybersecurity-related ones) remain unanswered, putting the site’s relevance and reputation into jeopardy. Hence, it is important to understand users’ participation in privacy and security discussions to promote engagement and foster the exchange of such expertise. Objective: Based on prior findings on online social networks, this work elaborates on the interplay between users’ engagement and their privacy practices in SO. Particularly, it analyses developers’ self-disclosure behaviour regarding profile visibility and their involvement in discussions related to privacy and security. Method: We followed a mixed-methods approach by (i) analysing SO data from 1239 cybersecurity-tagged questions along with 7048 user profiles, and (ii) conducting an anonymous online survey (N=64). Results: About 33% of the questions we retrieved had no answer, whereas more than 50% had no accepted answer. We observed that proactive users tend to disclose significantly less information in their profiles than reactive and unengaged ones. However, no correlations were found between these engagement categories and privacy-related constructs such as perceived control or general privacy concerns. Implications: These findings contribute to (i) a better understanding of developers’ engagement towards privacy and security topics, and (ii) to shape strategies promoting the exchange of cybersecurity expertise in SO.
