A One-Dimensional Energy Balance Model Parameterization for the Formation of CO2 Ice on the Surfaces of Eccentric Extrasolar Planets

Vidya Venkatesan, Aomawa L. Shields, Russell Deitrick et al.

Eccentric planets may spend a significant portion of their orbits at large distances from their host stars, where low temperatures can cause atmospheric CO2 to condense out onto the surface, similar to the polar ice caps on Mars. The radiative effects on the climates of these planets throughout their orbits would depend on the wavelength-dependent albedo of surface CO2 ice that may accumulate at or near apoastron and vary according to the spectral energy distribution of the host star. To explore these possible effects, we incorporated a CO2 ice-albedo parameterization into a one-dimensional energy balance climate model. With the inclusion of this parameterization, our simulations demonstrated that F-dwarf planets require 29% more orbit-averaged flux to thaw out of global water ice cover compared with simulations that solely use a traditional pure water ice-albedo parameterization. When no eccentricity is assumed, and host stars are varied, F-dwarf planets with higher bond albedos relative to their M-dwarf planet counterparts require 30% more orbit-averaged flux to exit a water snowball state. Additionally, the intense heat experienced at periastron aids eccentric planets in exiting a snowball state with a smaller increase in instellation compared with planets on circular orbits; this enables eccentric planets to exhibit warmer conditions along a broad range of instellation. This study emphasizes the significance of incorporating an albedo parameterization for the formation of CO2 ice into climate models to accurately assess the habitability of eccentric planets, as we show that, even at moderate eccentricities, planets with Earth-like atmospheres can reach surface temperatures cold enough for the condensation of CO2 onto their surfaces, as can planets receiving low amounts of instellation on circular orbits.

A Meta-Synthesis Study on the Glass Ceiling Factors in Türkiye

Burcu Akdeniz, N. Derya Ergün Özler

For the past 100 years, Turkishwomen have had the opportunity to obtain an education and enter the labor force due to the democratic regime established in 1923. Despite some economic and social barriers, they have taken advantage of these opportunities and advanced in their careers to some extent. However, as with all women around the world, they face barriers in their career paths. This study aims to analyze the scientific research studies on the glass ceiling syndrome conducted in Türkiye to gain detailed insights into people’s perception of the glass ceiling and capture their perspectives on the factors that contribute to it. This is a meta-synthesis study aimed at conducting a systematic review of selected qualitative studies and integrating their findings. A systematic search was conducted across local academic databases, namely, Dergipark and Tubitak Ulakbim-Equal. MAXQDA2022 software was used to code and analyze the articles. The factors forming glass ceiling defined by the studies were renamed as 18 subthemes in total and classified under three themes: (1) personal factors, (2) sociocultural factors and (3) organizational factors. Although the role of motherhood and work life balance was found to be the most frequently referred factor, some current research revealed that not only women but also men experience this syndrome in Türkiye, despite the patriarchal culture of the country. The study’s limitations are noted, and the implications and future research directions are discussed.

Information Commerce (i-Commerce) Usage and Purchase Decisions Among University Students During COVID-19

Norzaidi Mohd Daud, Raja Nur Hannah Fatimah Raja Mohd Hashimb, Anis Irdina Yang Asri et al.

Purpose – The purpose of this paper is to examine the relationship between information commerce usage and purchase decisions made by university students during the COVID-19 pandemic. Design/Methodology/Approach – Survey questionnaires were distributed to students at public and private universities through a variety of online platforms. Data was collected from 151 respondents within a two-week period and analyzed using IBM Statistical Package for the Social Sciences (SPSS) Version 26 for descriptive (i.e., mean, standard deviation, reliability test, model fit test) and inferential (i.e., correlation and regression for hypotheses testing) purposes. Findings and implications – The findings indicate that, while students engage in information commerce for its convenience, their usage of it is unrelated to the degree of trust. Nonetheless, price comparison has a sizable influence on how information commerce is used. Additionally, information commerce usage has an effect on purchase intention, while purchase intention is found to be a significant predictor of purchase decisions. Limitation – This study examined factors that influence the usage of information commerce among students in Malaysian universities, as well as their purchase intention, on a rather small sample size. Originality – This may be the first study to define information commerce usage, with its results confirming students’ purchase behavior and demonstrating that online shopping simplifies their lives. Surprisingly, the findings suggest that the degree of trust does not influence the usage of information commerce. This contradicts previous studies conducted by Anas et al. (2021) and Viktoria et al. (2021).

Blockchain and consumer behaviour: Results of a Technology Acceptance Model in the ancient wheat sector

Romeo Bandinelli, Gabriele Scozzafava, Bianca Bindi et al.

The importance of traceability in food products in regard to consumer preferences, the difficulty of certifications in communicating credence attributes, and concerns about food safety, have led consumers to ask for more information about the credibility of information reported on the label with the product itself, due to the importance of traceability in food products. An objective of this study is to analyze the benefits of implementing blockchain technology in the supply chain for ancient wheat, as a technology capable of sharing reliable information about the products easily along the entire value chain. In particular, the aim is to evaluate how the consumer reacts when confronted with a package of ancient wheat pasta for which all the information on its origin and processing methods is available. In order to achieve these results, a survey based on the Technology Acceptance Model has been developed and conducted in the Italian country. Result indicates the importance of identifying an independent variable that represents the degree of security when faced with a threat that creates a circumstance, condition or event that can lead to economic hardship, for example, data destruction, disclosure, modification, fraud, waste, and abuse. The strength of blockchain lies precisely in its ability to guarantee the immutability of data throughout the supply chain, providing the end consumer with a high-quality product.

Making Large Language Models Better Knowledge Miners for Online Marketing with Progressive Prompting Augmentation

Chunjing Gan, Dan Yang, Binbin Hu et al.

Nowadays, the rapid development of mobile economy has promoted the flourishing of online marketing campaigns, whose success greatly hinges on the efficient matching between user preferences and desired marketing campaigns where a well-established Marketing-oriented Knowledge Graph (dubbed as MoKG) could serve as the critical "bridge" for preference propagation. In this paper, we seek to carefully prompt a Large Language Model (LLM) with domain-level knowledge as a better marketing-oriented knowledge miner for marketing-oriented knowledge graph construction, which is however non-trivial, suffering from several inevitable issues in real-world marketing scenarios, i.e., uncontrollable relation generation of LLMs,insufficient prompting ability of a single prompt, the unaffordable deployment cost of LLMs. To this end, we propose PAIR, a novel Progressive prompting Augmented mIning fRamework for harvesting marketing-oriented knowledge graph with LLMs. In particular, we reduce the pure relation generation to an LLM based adaptive relation filtering process through the knowledge-empowered prompting technique. Next, we steer LLMs for entity expansion with progressive prompting augmentation,followed by a reliable aggregation with comprehensive consideration of both self-consistency and semantic relatedness. In terms of online serving, we specialize in a small and white-box PAIR (i.e.,LightPAIR),which is fine-tuned with a high-quality corpus provided by a strong teacher-LLM. Extensive experiments and practical applications in audience targeting verify the effectiveness of the proposed (Light)PAIR.

Estimating required flexibility for secure distribution grid operation considering the uncertainties of EV and PV

Manijeh Alipour, Omid Alizadeh-Mousavi

Renewable energy productions and electrification of mobility are promising solutions to reduce greenhouse gas emissions. Their effective integration in a power grid encounters several challenges. The uncertain nature of renewable energy productions as well as stochastic consumptions of electric vehicles introduce remarkable intermittency to a distribution grid and results in bi-uncertain characteristics of both supply and demand sides. One way to verify the secure grid operation within acceptable voltage and loading levels is to assess its required flexibility considering possible boundaries of uncertain variables. In this paper, first a comprehensive linear model of distribution grid considering all pertaining constraints is presented. Then, a flexibility estimation technique is proposed based on the feasibility study of the uncertain space of photovoltaic power productions and load containing electric vehicles. The proposed methodology uses grid monitoring data to determine grid state and to model uncertain parameters. The model is applied on a real low voltage (LV) system equipped with grid monitoring devices.

Multi-Point Detection of the Powerful Gamma Ray Burst GRB221009A Propagation through the Heliosphere on October 9, 2022

Andrii Voshchepynets, Oleksiy Agapitov, Lynn Wilson et al.

We present the results of processing the effects of the powerful Gamma Ray Burst GRB221009A captured by the charged particle detectors (electrostatic analyzers and solid-state detectors) onboard spacecraft at different points in the heliosphere on October 9, 2022. To follow the GRB221009A propagation through the heliosphere we used the electron and proton flux measurements from solar missions Solar Orbiter and STEREO-A; Earth magnetosphere and the solar wind missions THEMIS and Wind; meteorological satellites POES15, POES19, MetOp3; and MAVEN - a NASA mission orbiting Mars. GRB221009A had a structure of four bursts: less intense Pulse 1 - the triggering impulse - was detected by gamma-ray observatories at 131659 UT (near the Earth); the most intense Pulses 2 and 3 were detected on board all the spacecraft from the list, and Pulse 4 detected in more than 500 s after Pulse 1. Due to their different scientific objectives, the spacecraft, which data was used in this study, were separated by more than 1 AU (Solar Orbiter and MAVEN). This enabled tracking GRB221009A as it was propagating across the heliosphere. STEREO-A was the first to register Pulse 2 and 3 of the GRB, almost 100 seconds before their detection by spacecraft in the vicinity of Earth. MAVEN detected GRB221009A Pulses 2, 3, and 4 at the orbit of Mars about 237 seconds after their detection near Earth. By processing the time delays observed we show that the source location of the GRB221009A was at RA 288.5 degrees, Dec 18.5 degrees (J2000) with an error cone of 2 degrees
