A Semantic and Optimized Focused Crawler Based on Semantic Graph and Genetic Algorithm

A focused crawler automatically retrieves, organizes, and extracts specific topic-related information from the internet for analysis and application. Currently, most focused crawlers assess the relevance of web pages to a given topic through methods such as keyword matching, semantic analysis, and link structures. However, these existing focused crawlers suffer from issues such as misleading directions and reduced accuracy due to the lack of semantic analysis of topic terms, as well as biased computation of topic relevance caused by the absence of effective weighting factors. To solve the above-mentioned problems, this study proposes a semantic and optimized focused crawler based on Semantic Graph and Genetic Algorithm. The proposed crawler eliminates ambiguous terms by constructing a semantic graph, optimizes the weighting factors of topic relevance with asymmetry by using a genetic algorithm, and combines both above two points to predict the priority of each unvisited hyperlink. The experiment results indicate that the proposed SG-GA Crawler improves the evaluation indicators compared with the other three focused crawlers, including VSM Crawler, SSRM Crawler, and SG Crawler. More specifically, the percentage improvement achieved by the proposed method exceeds 19%, 19%, and 13% in terms of three evaluation indicators, including the number of relevant web pages, acquisition rate, and average relevance, respectively. In conclusion, the proposed focused crawler can grab more quantity and higher quality topic-related web pages from the Internet.

Discursive AI Infrastructures: Envisioned and Overlooked Museum Futures

ABSTRACTPrompted by recent innovations, artificial intelligence (AI) is increasingly being discussed across the museum sector regarding its implications for institutional roles and practices. However, AI in particular, is an ambiguous term, a ‘black box’ which is capable of containing and reflecting numerous values and ideals (Crawford, 2021). This paper positions discourse around AI as a ‘discursive’ infrastructure, capable of not only embodying ideals but also shaping and justifying certain institutional practices and roles. This paper thematically analyses 115 pieces of grey literature produced and shared by professional governance bodies in the museum sector from 1995–2023, mainly across Canada, the United Kingdom, and the United States. In doing so, it identifies four preliminary themes encompassing shifts in discourse over time which give shape to a contemporary discursive infrastructure. This prompts timely critical reflections of museum professionals and stakeholders on both imagined and overlooked public roles, responsibilities, and practices of the museum in relation to AI.

Contractual challenges in renewable energy projects: The role of ADR in managing risks and disputes

Renewable energy projects are increasingly pivotal in the global transition to sustainable energy systems. However, these projects face unique contractual challenges that can lead to disputes and risks, impacting project timelines and costs. This paper explores the critical role of Alternative Dispute Resolution (ADR) mechanisms in managing and mitigating these challenges. The study highlights common contractual issues encountered in renewable energy projects, including ambiguities in contract terms, scope changes, and performance obligations. It examines how ADR methods, such as mediation, arbitration, and adjudication, offer effective solutions for resolving disputes and minimizing disruptions. By analyzing case studies and industry practices, the paper demonstrates the efficacy of ADR in addressing specific issues such as delays, cost overruns, and compliance failures. The findings underscore the importance of incorporating ADR clauses into contract frameworks to enhance dispute resolution processes and risk management strategies. The paper concludes with recommendations for integrating ADR into contractual agreements and emphasizes the need for stakeholders to proactively address potential disputes to ensure project success.

Jordanian Cybercrime Law No. (17) of 2023 between Regulating Social Media Sites and Restricting Freedom of Opinion

The primary objective of this research is to study the Jordanian Cybercrime Law No. (17) of 2023 between regulating social media sites and restricting freedom of opinion. In addition, it clarifies the concept of cybercrimes and how to control social media sites while preserving citizens’ rights to freedom of expression. In terms of balancing digital security and controlling social media sites. Defining concepts and terms, such as “regulating” social media sites and “restricting freedom of opinion,” is crucial to understanding the law's impact on users. Monitoring and implementing the law by the competent authorities to avoid excessive violations of individuals’ rights. The researcher used the descriptive analytical method, as well as the inductive method, and the legal text analysis tool was used. This research has reached several results, the most important of which are that the Jordanian cybercrime law has used broad, vaguely defined, inaccurate, ambiguous, and non-specific terms, such as fake news. Even though these texts do not meet the requirements of international law regarding drafting legal texts precisely enough to allow individuals to regulate their behavior accordingly. In addition, the Jordanian cybercrime law focused on the penal and punitive dimensions and did not include any institutional or preventive measures to reduce negative phenomena in the digital environment. This research has reached several recommendations, the most important of which are that the Jordanian legislator must reconsider amending legal texts that are unfair to internet users in a way that leads to the adoption of balanced legal texts compatible with basic rights. These rights include the right to exchange information, the right to express opinions and ideas, and the right to privacy, which the Jordanian Constitution guarantees in Article (7).

Accuracy and reliability improved GNSS partial ambiguity resolution assisted by a MEMS inertial measurement unit

Traditional partial ambiguity resolution (PAR) methods based on integer least-squares (ILS-PAR) assume that the ambiguity terms are unbiased integers, which is seldomly true in challenging environments of the Global Navigation Satellite System (GNSS). The bias will lead to unreliable positioning solutions. This study proposes a reliable PAR method based on the tightly coupling of GNSS and inertial navigation system (INS) and the solution separation with external solution (SSE) statistical testing algorithm. First, the inertial measurement unit (IMU) mechanization results are compensated using the latest fixed real-time kinematic (RTK) solutions, thus high-accuracy INS predictions are obtainable at the current GNSS epoch. Second, the SSE method based on double-differenced (DD) carrier-phase measurements are applied to select and validate the ambiguity subset and perform the GNSS/INS integration. A dynamic vehicular experiment with a low-cost microelectromechanical systems (MEMS) device has been conducted and the results indicate that the proposed method can ensure good performance of both accuracy and reliability.

An Ethical Analysis of the Online Content of Assisted Reproductive Technology Centers in Bangladesh.

Assisted reproductive technologies (ARTs) have become a widely utilized medical technology for treating infertility worldwide. However, societies and countries have applied these technologies in accordance with their cultural practices and belief systems. This paper presents an overview of ART providers in Bangladesh and analyzes their online content in addressing potential infertile couples. Examining the topic within the context of socio-economic and public health challenges in Bangladesh, particularly overpopulation, poverty, and lack of education, the research conducted a web content analysis of ART providers in Bangladesh from July 1 to September 1, 2023. Twenty active ART providers were identified using Google searches and an exploratory key. The analysis considered locations, landing page information, ethical standards, quality certification, foreign affiliations, and success rates. The findings revealed a concentration of centers in urban areas, raising concerns about equitable access. The absence of regulation and guidelines, coupled with the lack of ART clinic registration, highlighted potential risks to patient well-being. Landing page statements utilized highly emotive language and ambiguous terms, raising ethical concerns. The absence of explicit mention of quality standards, including ISO 9001:2000 certification, indicated potential gaps in transparency. Foreign affiliations were employed for credibility, raising concerns of misleading advertising. Limited and ambiguous reporting of success rates posed challenges for informed decision-making. Evident exploitative and commercialized practices raised concerns about potentially commodifying reproductive services. The study emphasizes the need for regulatory frameworks, transparency in reporting, adherence to ethical advertising, and increased cultural sensitivity to enhance the ethical standards of ART providers in Bangladesh.

Exploring the ambiguity in the anatomical terminology among Dental professionals

BackgroundAnatomical terms in medical literature have been used with varying meanings, leading to confusion in clinical practice. This study aims to investigate the ambiguity of anatomical terms in clinical dentistry.MethodsDentists who have undergone specialised training with at least one year of clinical experience were recruited to participate in the study. They were requested to localize specific terms on a skull and provide explanations based on their experience or opinion. All data were recorded, and then descriptive statistics were used for analysis.ResultsSeventy-eight participating dentists gave their consent and were eligible to study. For each anatomical term presented to dentists at least two meanings were provided, with some terms having up to eight interpretations. While most meanings were consistent with medical or dental literature, some responses revealed new interpretations not documented in textbooks.ConclusionsDentists expressed anatomical terms with diverse meanings, possibly influenced by their various subspecialties. It is crucial to acknowledge this variability to prevent confusion. Emphasizing the consistent use of anatomical terms among dental professionals in the future is essential.

Assessing Nonlinear Polarization in Electrochemical Cells Using AC Impedance Spectroscopy

Electrochemical energy storage and conversion devices are used to power a range of electrical loads including portable electronics, electric vehicles, and utility grids. The energy efficiency of these systems decreases with increasing current load due to energy losses (in the form of heat) associated with different processes. Electrochemical impedance spectroscopy (EIS) is a nondestructive technique commonly used to assess rate-limiting steps in electrochemical devices. Most EIS measurements for energy storage devices are only performed around open-circuit and do not probe system behavior under non-zero biases where these devices operate. Despite its widespread use, this approach does not provide information about the relative overpotentials associated with coupled nonlinear processes (e.g., diffusion limited redox reactions) commonly encountered in these systems. Furthermore, ambiguous terms such as equivalent series resistance and interfacial resistance can lead to confusion and data misinterpretation. For example, Ohm’s law cannot be applied to calculate nonlinear overpotentials using a resistance that was measured from a locally linear response.To determine overpotentials in nonlinear systems using EIS, one must integrate the individual resistive elements of the equivalent circuit as a function of steady state current. Recent experimental work has used this method to decouple ohmic, kinetic, and transport overpotentials in redox flow batteries. In these prior studies, impedance elements were derived, but analytical expressions for the corresponding overpotentials were not presented.While integrated resistance measurements are a powerful experimental tool, a more rigorous mathematical framework describing the approach is needed. The present work bridges this gap by: (i) deriving a general impedance expression for coupled charge transfer and diffusion processes and (ii) integrating the individual resistive elements as a function of steady-state current to obtain global polarization relationships. Analytical expressions for diffusion overpotentials are obtained for special cases, and numerical methods are applied when closed-form expressions do not exist. The work considers three model electrode geometries (planar, cylindrical, and spherical) and two diffusion boundary types (reflective and transmission). Finally, this treatment is extended to macroscopically homogenous porous electrodes which are relevant for describing practical devices.This presentation will highlight how measuring impedance at different steady-state biases provides critical insights on the rate-limiting processes in energy storage devices. While this work focuses on a simple Faradaic charge transfer process, the method can be used to evaluate other nonlinear phenomena in electrochemical power supplies. For example, the resistance of passive films (e.g., solid electrolyte interphase layer) in Li-ion batteries is typically only probed near open-circuit. Similarly, literature on solid-state batteries commonly uses ambiguous terms such as interfacial resistance to describe rate-limiting processes. For these more complex systems, integrating the resistive elements can provide insights on how these phenomena influence device efficiency. Overall, combining these experimental observations with physical models derived using the approach illustrated herein represents a powerful tool to guide component/system design and improve device performance.

Product Quality in the Circular Economy: A Systematic Review of its Definition and Contexts in Scientific Literature

AbstractIn the context of the Circular Economy (CE), quality is one of the most widely used keywords, but generally perceived as an ambiguous term without further definition or explanation. The present paper analyzes the use of the term product quality in the context of the CE through a systematic literature review including 132 peer-reviewed journal articles. The results reveal that the term quality, although not always explicitly defined, is associated with a variety of topics, namely market value, customer perspective, functionality, technical attributes, longevity, R-strategies and design, and environmental aspects. The aforementioned topics are used in different application contexts and partly show reciprocal relationships amongst each other. They further refer to the three sustainability perspectives (environmental, economic and social). The quantification of quality is observed to be rather limited and mainly based on assumptions. When it is quantified, technical properties, functionality and longevity are most frequently mentioned aspects, which are used within circularity or environmental impact assessment. While acknowledging the limitations arising from the scope of the included studies, which may be influenced by the keywords chosen, the review revealed that quality in the CE literature is complex and ambiguous. Therefore, for future research, we recommend authors to clearly define quality and its characteristics in the context of their respective research. By doing so, a better interpretation and comparability of the results can be achieved. Graphical Abstract

Specialization: A multidimensional and integrative perspective

AbstractSpecialization remains as a controversial and ambiguous term in ecology. Although it has been usually measured using a dichotomic and simplified classification of specialists and generalists, its nature is by far more complex. In the context of biotic interactions, assigning these two labels is usually based on the number of interacting partners (one or few vs. many). Here, we provide a more precise, quantitative, and objective interpretation of the specialization phenomenon combining three different dimensions (specificity, preference, and selectivity) that offer complementary information to quantify specialization. Hence, partner richness is a metric associated with the specificity, Simpson's evenness is related to the preference and d′ index to the selectivity of the biotic interactions. Consequently, we propose a 3D specialization space combining these three metrics which allows to identify the degree of biotic specialization fleeing from its simplified historical interpretation. The proposed space was subsequently evaluated in five natural interacting systems (host–parasite, plant–ant, plant–pollinator, plant–seed disperser, and mycobiont–cyanobacteria) using available data comprising 116 networks with quantitative observations. The results indicate the prevalence of a lax specialization, where most organisms tended to show low values in at least one of the metrics. Predominantly, observations showed high values of specificity and low values of preference and selectivity. This relaxed specialization provides advantages of being specialized, without sentencing it when being too tight. The implementation of this framework provides a useful tool that allows to identify specialization in a more objective, integrative, and universal way for future specialization studies.

What Does It Mean to be "Plausible"?

This article explores what ‘plausible’ means in statements about legal evidence and shows that it is highly ambiguous. Twelve different meanings of ‘plausibility’ are identified and distinguished from each other by definitions. Contrary to what has been claimed by some evidence scholars (Allen and Pardo, 2019), the article shows that all uses of ‘plausibility’ can be captured in terms of probability. The author also shows that the exposed ambiguity is deeply problematic for legal practice and legal scholarship. The fundamental principle of justice that ‘like cases should be treated alike’ is endangered when the standard of proof is expressed in an ambiguous way, and the scientific testability of hypotheses about legal fact-finding is undermined when these hypotheses are formulated in ambiguous terms.

"It Is A Purposefully Ambiguous Term": Examining Emerging Adults' Definitions of Hooking Up and How They Vary by Sex/Gender and Educational Background.

The majority of past work on hooking up among emerging adults uses a researcher-led definition and often uses college student samples. The purpose of this study was to qualitatively examine participant-led definitions of hooking up using a large sample (N = 701) of college-attending and non-college emerging adults. Most definitions included behaviors (91.7%), a partner type (64.3%), and references to commitment (69.2%). However, considerable variation in definitions within these categories was identified, in particular with reference to commitment. In our sample, definitions attended to what a hook "is" and "is not" as it relates to commitment. Hookup characteristics were also discussed in definitions, including frequency of hooking up, decision making, sexual health and safety, and purposes for hookups. Participants regularly referenced other common terms in relation to hooking up, including one-night stands, casual sex, no strings attached, and friends with benefits. For some, hookups were similar to these other types of casual sex experiences, whereas for others hooking up was distinct. We also quantitatively examined proportional differences in definitional categories and sub-categories based on sex/gender (men vs. women) and educational background (college-attending vs. non-college). Although some proportional differences were found, in general men and women and college-attending and non-college emerging adults defined hookups in similar ways. Programming focused on emerging adult romantic and sexual relationship education would benefit from addressing these subtle, but meaningful variations, as individuals enact hookup scripts based on how they define their encounters. Future opportunities for research to integrate both researcher-led and participant-led definitions of hooking up are discussed.

A metapragmatic stereotype‐based account of reclamation

AbstractGroup‐based slurs are words that express derogatory attitudes toward some group demarcated by a property that has historically caused social antagonism, for example, gender or ethnicity, among others. Reclamation, in turn, is the process whereby a slur starts being used non‐derogatorily by members of the target group to express a positive attitude. Some content‐based theories of slurs (which pin the derogatory force of such terms on their conventional meaning) account for reclamation by arguing that it involves a change in meaning so that reclaimed slurs are ambiguous. But these theories face a challenge, namely to account for the difference between reclaimed slurs and run‐of‐the‐mill ambiguous terms, whose felicitous uses do not seem to be restricted to in‐group speakers. In this article, we argue that the Reclamation Worry is not a problem for content‐based theories of slurs by advancing an account of reclamation that is compatible with such views. As we shall argue, such a theory must rely on the sociolinguistic dimension of such terms.

The Importance of Ontological Commitment and Linguistics in Relation to the Elucidation of Design Requirements

One of the design process’s earliest and most critical stages is establishing and determining requirements. Design requirements are often expressed through language, whether in written documents, diagrams, or verbal discussions in terms of the client’s “wants” and “needs” or balancing what they can “afford.” Designers use of quotes around “wants,” “needs,” and “afford” signals ambiguity or doubt in the meaning of the terms. The language used during early discourse is crucial for expressing and translating theseambiguous terms into specific unambiguous design requirements, which significantly shape and constrain possible solutions. In philosophy, this concept is known as ontological commitment. Embedded language in requirements documents, expressed through constraints, objectives, and functions, establish the ontological commitment to a specific solution space. Prior marine design research has focused on the wicked problem of requirements elucidation, with the goal visualizing potential solutions derived from language, and a more direct link to ontological commitment was developed by Andrews in the concept of style Duchateau (2016) van Ores (2011) Andrews (2012). However, the role and impact of linguistics in translating and interpreting uncertain or ambiguous terms into specific design requirements has been largely overlooked. This paper presents modern direct examples of ontological commitment from requirements development for the Littoral Combat Ship.

Risk overbounding for ionospheric gradient monitor using geometry-free double differenced carrier phase measurements

Ionosphere anomaly can cause large spatial gradients in the double-differenced carrier phase (DDCP) measurements. Taking advantage of this characteristic, the ionospheric gradient monitor (IGM) is designed with multiple ground reference stations to detect threatening ionospheric gradients for safety of life applications. An optimal IGM should be most sensitive to ionospheric gradients and least sensitive to other errors. However, current IGM suffers from the influence of tropospheric error, which can degrade monitor performance under extreme weather conditions by causing risks of false alarms and missed detections. To address this issue, an alternative IGM is proposed using the geometry-free combination of DDCP as the test statistic. Ambiguity resolution procedure is designed for estimating the ambiguity term in the test statistic. The risk induced by the wrong ambiguity fix and tropospheric error are analyzed and bounded with required averaging period and minimum baseline length. The results show that the proposed theoretical IGM is capable of achieving probability of false alarm of 10–8 and probability of missed detection of 10–6 with a filtering period of 612 s and baseline length of 371.7 m or a filtering period of 544 s and baseline length of 384.4 m. The experimental results using data collected from Hong Kong Satellite Positioning Reference Station Network demonstrate that the performance of the proposed theoretical IGM is comparable to that of the existing detection algorithm.

Evolution of Various Legal Dimensions for Flat-buyers in Bharat

This paper delves into the dynamic landscape of laws regulating the rights and responsibilities of flat buyers in India, tracing the evolution of the legal framework from its inception to the present day. The journey unfolds against the backdrop of India's rapidly growing real estate sector, characterized by its multifaceted challenges and opportunities. The study encompasses an in-depth examination of key legislations, judicial precedents, and policy interventions that have shaped the rights and protections afforded to flat buyers. Beginning with an exploration of early property laws, the paper elucidates the factors that necessitated specialized regulations governing the purchase of flats and apartments. The advent of cooperative housing societies and the Real Estate (Regulation and Development) Act, 2016, marks significant milestones in this evolution, with an emphasis on consumer protection, transparency, and accountability. The analysis extends to the interplay between statutory provisions and evolving judicial interpretations, highlighting landmark cases that have influenced the legal landscape. Furthermore, the paper investigates the impact of technological advancements, such as online property transactions and blockchain, on the legal aspects of flat purchases. It scrutinizes the role of digitization in enhancing transparency, reducing fraud, and expediting dispute resolution mechanisms.

Terminological discrepancies and novelties in the histological description of the female genital system: proposed amendments for clinical-translational anatomy

Histological terminology of the female genital organs is currently a part of the internationally accepted nomenclature Terminologia Histologica (TH), the latest edition of which dates back to 2008. Many new discoveries have been documented within 16 years since then, and many discrepancies have been found. This paper aims to revise the terminology from clinical and educational perspectives comprehensively. The authors thoroughly searched the current edition of “Terminologia Histologica: International Terms for Human Cytology and Histology,” focusing on missing and controversial terms in the chapter Female genital system. The authors identified six controversial and ambiguous terms and four missing important histological terms. The authors also discussed the addition of less used eponymic terms in the histological description of female genital organs like Hamperl cells, Popescu cells, Kroemer lacunae, Balbiani bodies, Call–Exner bodies, membrane of Slavianski, nabothian cysts, or anogenital sweat glands of van der Putte. We expect the second and revised edition of the TH to be published soon and hope that the Federative International Program on Anatomical Terminology will approve and incorporate all these propositions and suggestions. We also strongly recommend using the official internationally accepted Latin and English histological nomenclature—the TH, either in oral or written form, both in theoretical and clinical medicine.

Logic and Law: A Matter of Values Behind Content and Form

Abstract This special issue on Logic and Law consists of four research papers and one interview focusing on epistemological reflections on relationships between logic and law, whether in a reductionist or complementary approach. Logic aims to elucidate through formal frameworks, yet it often grapples with the intricate nuances of everyday legal discourse. While law endeavors to delineate permissible conduct within defined jurisdictions, it often encounters challenges stemming from the ambiguity of terms, leading to frequent judicial interpretations and the perception that proliferating exceptions undermines the efficacy of the rule itself.

Long-Term Coherent Integration Algorithm for High-Speed Target Detection.

Long-term coherent integration (CI) can effectively improve the radar detection capability for high-speed targets. However, the range walk (RW) effect caused by high-speed motion significantly degrades the detection performance. To improve detection performance, this study proposes an improved algorithm based on the modified Radon inverse Fourier transform (denoted as IMRIFT). The proposed algorithm uses parameter searching for velocity estimation, designs a compensation function based on the relationship between velocity and distance walk and Doppler ambiguity terms, and performs CI based on the compensated signal. IMRIFT can achieve RW correction, avoid the blind-speed sidelobe (BSSL) effect caused by velocity mismatch, and improve detection performance, while ensuring low computational complexity. In addition, considering the relationship between energy concentration regions and bandwidth in the 2D frequency domain, a fast method based on IMIRFT is proposed, which can balance computational cost and detection capacity. Finally, a series of comparative experiments are conducted to demonstrate the effectiveness of the proposed algorithm and the fast method.

The Christology of the Church of the East

After setting out the background of the early history of the Church of the East, this contribution focuses on the Syriac sources of the fifth to seventh centuries which are witnesses to the development of the ‘two-nature’ Christology of the Church of the East, situated outside the Roman Empire during this formative period. Special attention is paid to the ambiguous term qnoma, which is used to render hypostasis in the Chalcedonian Definition, but which, for native Syriac authors, has the different sense of ‘defining characteristic’. The problematic designation ‘Nestorian’ should be avoided since it implies completely different things to different parties. Some final thoughts are given to the ongoing significance of the tradition of the Church of the East in its various present-day manifestations.
