Environmental And Socioeconomic Effects Of Roundtable On Sustainable Palm Oil Certification: A Systematic Review And Meta-Analysis, Kibrom T. Sibhatu, Matin Qaim

All Peer-Reviewed Publications

Palm oil is the most widely produced and consumed vegetable oil worldwide, but its production is associated with deforestation and other environmental and social problems. Roundtable on Sustainable Palm Oil (RSPO) is the only internationally-recognized voluntary certification standard aimed at mitigating such problems. Many studies examine RSPO’s effects on particular outcomes in specific contexts, but a consolidated global assessment is lacking. Here, we systematically review the literature and identify 53 original studies covering RSPO effects in various countries of Asia, Africa, and Latin America. Where data availability permits, we also conduct meta-analysis. Results reveal that RSPO can lead to environmental …

A Robust Hybrid Security Framework: Integrating Multi-Layered Text Encryption With Barcode-Based Steganography, Mohamed Sayed, Talaat M. Wahbi, Farooq Abdalwahab Haboub

BAU Journal - Science and Technology

The widespread use of the Internet is causing increasing security concerns regarding online communications. One method for achieving secure communication between authorized parties is steganography. We herein employ multilevel technologies, including compression, encryption, barcoding, and steganography to secure a secret text message. Type I multilevel steganography is used with a two-level setup. The first level uses enhanced least significant bit (secure LSB-L1) image steganography; the output is a stego-image file, the cover is an image file, and the secret data in this level is English text. The output from the first level is encrypted using the RSA algorithm, and the …

Śaṅkha-Dvīpa And The Swahili Littoral: Reconstructing India–East Africa Contacts Before The Common Era, Narendra Vijayasimha

Zamani: A Journal of African Historical Studies

This article is the first focused attempt to explore India–East Africa relationships in the Bronze Age and early Iron Age, approximately two to three millennia before the Common Era (3000–300 BCE) from a puranic perspective. While extensive scholarship exists on medieval and later Indo–African exchanges, the pre-Common Era period has remained underexplored. Drawing on Purāṇic cosmographies, Greco-Roman geographical accounts, African archaeology, and Indian Ocean trade studies, this research reconstructs possible networks of contact facilitated by monsoon navigation and long-distance exchange. Methodologically, the article integrates textual exegesis, comparative cosmography, and archaeological correlation. The findings suggest that Indian conceptions of Śaṅkha-dvīpa reflect …

Creative Constructions In Asian And World Englishes - And What They Teach Us, Edgar W. Schneider

Journal of English and Applied Linguistics

"Creative constructions" are defined as patterns which deviate slightly but noticeably from grammatical, fully licensed structures in English (and are therefore sometimes branded as "wrong"), inviting specific cognitive associations to make sense of them. It is argued that such structures offer a window into the nature of the cognitive manipulation of linguistic innovations and change. The concept is related to creativity in literature and lingua franca English, and it is surveyed theoretically by asking how established grammatical theories (like traditional grammar, structuralism or generativism) or more recent approaches to the nature of grammar (usage-based linguistics, construction grammar, and complex systems …

Character Education Across School Contexts: A Qualitative Study Of High- And Regular-Performing Schools In Indonesia, Heri Retnawati, Zurqoni Zurqoni, Mukhamad Ilyasin, Hasan Djidu, Kartianom Kartianom, Ezi Apino

The Qualitative Report

This qualitative study explores how character education is understood, organized, and enacted across two types of junior high schools in Indonesia: High-Performing Schools (HPS) and Regular-Performing Schools (RPS). Using semi-structured interviews with school leaders, teachers, parents, students, and school committee members from nine schools across three provinces, we examined how institutional conditions and relational practices shape the implementation of character education. Analysis generated four themes: variation in program management approaches, differences in implementation structures and stakeholder involvement, school inputs shaping program capacity, and community perceptions of character education outcomes. Findings show that HPS tend to institutionalize character education through structured …

Accounting And Economic System Classification: An Adverse Effect Of The Misconceptualization Of Capital, Henry Zeno Chalu

Business Management Review

This paper discusses the influence of accounting on economic system classification. Particularly, it traces how a misconception of the accounting term ‘capital’ led to a misleading characterization of capitalism and socialism as inherently oppositional economic systems. This misunderstanding stems from neglect of the two complementary modes of thought on which accounting as a science rests: reasoning, which is the conceptual, idealistic dimension, and proving, which is the technical, physicalist dimension. Both modes are integral to the construction of most of the accounting terms used in economics. If an accounting conceptualization had been followed, capitalism and socialism would not …

Teachers’ Awareness Of Family Engagement In Multilingual Education, Sedighe Zamani Roodsari

Journal of Multicultural Affairs

This study investigated public school teachers’ awareness of family engagement as a linguistic and cultural resource for multilingual students. Multilinguals are typically described as individuals who can communicate in more than one language, with English not being their native language, and their linguistic choices are influenced by societal norms and systems (Šifrar Kalan et al., 2024; Wei, 2008). Preparing pre-service teachers to enhance opportunities for multilingual students remains a critical need in teacher education programs, as they strive to move beyond monolingual ideologies in their teaching practices (Cárdenas Curiel et al., 2024; Kim & Choi, 2020; Williams & Ewing, 2019). …

How Gyms Should Use Commitment Devices: The Role Of Deposit Contracts In Attracting Consumers, Zehua Hei, Alan Morse

Global Sport Business Journal

Amid growing health concerns, increased competition among fitness centers, and declining staff-to-customer ratios, gym operators are seeking effective ways to reduce customer attrition. Drawing on Prospect Theory, this study examines how commitment devices in gym promotions (e.g., deposit contracts and transformation challenges) influence consumers’ intentions to join a gym. Two experiments with 609 participants (Study 1 = 204; Study 2 = 405) investigated the mediating role of perceived attractiveness and the moderating role of contractual flexibility. Results indicate that membership options incorporating a commitment device were perceived as more attractive, leading to stronger registration intentions. However, this effect was observed …

A Scoping Review Of Sycophancy In Large Language Models: Operational And Theoretical Recognition, Kallen Zhou, Manning Littlejohn, Isabella Garrard

Endeavors: Mississippi State Undergraduate Research Journal

As large language models (LLMs) usage grows across different domains, sycophancy, the tendency for output to align with users, is increasingly being recognized as a primary issue arising from applying LLMs into critical areas. Current research has provided a variety of theoretical definitions, mitigation techniques, and quantification for sycophancy. However, there is little to no consistency across different papers. This scoping review seeks to connect different works on LLM sycophancy by identifying themes in theoretical definitions, measurement methods, and inducement techniques of sycophancy. By analyzing 26 papers (preprints, conference proceedings, and journal articles) from arXiv, ACL Anthology, and Scopus, this …

Algorithmic Monocultures In Hiring, Rishi Bommasani, Sarah H. Bana, Kathleen A. Creel, Dan Saul Jurafsky, Percy Liang

Economics Faculty Articles and Research

Many employers screen job applicants with algorithms built by the same few algorithm vendors. We hypothesize that algorithmic monoculture leads to the same individuals and members of the same racial groups facing rejection. We acquire and analyze a novel dataset of 3 million applicants submitting 4 million applications where all the applications are screened by algorithms built by the same vendor. We find clear racial disparities in applicant outcomes. Of all applications submitted by Asian and Black applicants, 14.74% and 25.87% are submitted to positions that adversely impact Asian and Black applicants, respectively, according to U.S. employment discrimination standards. Individuals …

It was based on the theoretical model of feedback literacy and used a transcendental-phenomenological design to fulfill its purpose. The participants were seven students from a private school in Cali, Colombia. These students were in the first unit of the mathematics class and interviewed in depth. The data analysis had several phases: epoche, horizontalization and units of meaning, textural and structural description, and composite description. We found that students' relation to feedback was characterized by a predominantly passive-receptive role …

Mapping Seafloor Habitats And Characterizing Demersal Reef Fish Communities On The West Florida Shelf Across Multiple Spatial Scales Using Multibeam Sonar And Underwater Video, Alexander R. Ilich

USF Tampa Graduate Theses and Dissertations

In this dissertation, I examine the role of spatial scale in deriving seafloor terrain attributes, modeling benthic habitat, and analyzing ecological patterns of the demersal reef fish communities on the West Florida Shelf (WFS), with implications for improving predictive habitat mapping and understanding fish-environment relationships. Spatial scale plays a central role in benthic habitat mapping and ecological inference, influencing how terrain attributes are derived, how habitats are modeled, and how ecological responses are manifested. This work integrates multiscale terrain analysis, acoustic remote sensing, and community ecology to evaluate how spatial scale influences both physical habitat representation and ecological analysis.

Passed Through Or Pushed Back? Exchange Rate Effects On Manufacturing Trade Prices In Indonesia And The Asean Plus Three, Fatikha Rizky Kurnia, Miguel Angel Esquivias, Wee-Yeap Lau, Unggul Heriqbaldi

Bulletin of Monetary Economics and Banking

This study analyzes the Exchange Rate Pass-Through (ERPT) on export and import prices in Indonesia’s manufacturing trade with ASEAN Plus-three countries (China, Japan, and South Korea) using monthly data from 2016 to 2022. Employing the Nonlinear (NARDL) models, we examine the degree and asymmetry of ERPT across five key manufacturing sectors for each partner. The NARDL model confirms asymmetric price responses to currency appreciation and depreciation in several sectors. The findings reveal significant sectoral and country-specific variations. Some export sectors experience complete pass-through in the short term but shift to negative complete passthrough in the long run. Meanwhile, imports from …
