Fostering Spatial Ability Development In And For Authentic Stem Learning, Caiwei Zhu, Chloe Oi-Ying Leung, Eleni Lagoudaki, Mariana Velho, Natalia Segura-Caballero, Dietsje Jolles, Gavin Duffy, Gunter Maresch, Marianna Pagkratidou, Remke Klapwijk

Articles

Empirical interdisciplinary research has explored the role of spatial ability in STEM learning and achievement. While most of this research indicates that fostering spatial thinking in educational contexts has the potential to positively impact students’ enrollment and performance in STEM subjects, there is less agreement on the best approach to do so. This article provides an overview of various types of effective spatial interventions and practices in formal or informal educational contexts, including targeted training of STEM-relevant spatial skills, spatialized curricula embedded in schools, integrated STEM practices addressing students’ use of spatial skills, and spatial activities in informal STEM education. …

Persuasive Communication Systems: A Machine Learning Approach To Predict The Effect Of Linguistic Styles And Persuasion Techniques, Annye Braca, Pierpaolo Dondio

Articles

Prediction is a critical task in targeted online advertising, where predictions better than random guessing can translate to real economic return. This study aims to use machine learning (ML) methods to identify individuals who respond well to certain linguistic styles/persuasion techniques based on Aristotle’s means of persuasion, rhetorical devices, cognitive theories and Cialdini’s principles, given their psychometric profile.

Discovering Child Sexual Abuse Material Creators’ Behaviors And Preferences On The Dark Web, Vuong Ngo, Rahul Gajula, Christina Thorpe, Susan Mckeever

Articles

Background: Producing, distributing or discussing child sexual abuse materials (CSAM) is often committed through the dark web in order to remain hidden from search engines and regular users. Additionally, on the dark web, the CSAM creators employ various techniques to avoid detection and conceal their activities. The large volume of CSAM on the dark web presents a global social problem and poses a significant challenge for helplines, hotlines and law enforcement agencies.

Objective: Identifying CSAM discussions on the dark web and uncovering associated metadata insights into characteristics, behaviours and motivation of CSAM creators.

Participants and Setting: We have conducted an …

Post-Conflict Reconciliation In Ukraine, Elena Baylis

Articles

Reconciliation mechanisms should be a core component of transitional justice in Ukraine. The nature of this conflict as a war justified by claims about history, identity, and legitimacy suggests that there will be a need for post-war reconciliation initiatives. Such reconciliation measures would be intended to enable Ukraine’s Russian, Ukrainian, and other communities to live together constructively within the same state. The goals of social reconciliation also converge with Ukraine’s long-term, political aims vis-à-vis both Russia and the European Union. This paper addresses three types of reconciliation measures that are important for post-conflict Ukraine. Instrumental mechanisms to engage post-conflict social …

The International Legal Order And The Rule Of Law, Vivian Grosswald Curran

Articles

This article addresses whether international law today is capable of instituting the rule of law. It offers a renewed look at the internationalists who brought us modern international law, such as Lauterpacht, Cassin and Lemkin. They tenaciously worked at placing the individual’s right to life and to human dignity front and center in international law while also preserving peace among states. Their struggle began in earnest first in the interwar years after the “war to end all wars” (1918 – 1939), and then again in 1945 after yet another, still worse, world war had occurred, devastating Europe, but leaving the …

Cognitive Effort Avoidance In Veterans With Suicide Attempt Histories, James M. Bjork, Chelsea S. Rooney, Lisa K. Straub, David M. N. Garavito, Andrew Westbrook

Articles

Suicide attempts (SA) are increasing in the United States, especially in veterans. Discovering individual cognitive features of the subset of suicide ideators who attempt suicide is critical. Cognitive theories attribute SA to facile schema-based negative interpretations of environmental events. Over-general autobiographical memory and facile solutions in problem solving tasks in SA survivors suggest that aversion to expending cognitive effort may be a neurobehavioral marker of SA risk. In veterans receiving care for mood disorder, we compared cognitive effort discounting and evidence-gathering in a beads task between veterans with (SAHx+; n = 26) versus without (SAHx-; n = 22) a history …

Article 9 Foreclosures: When Is A Sale Not A Sale?, David G. Carlson

Articles

Article 9 of the Uniform Commercial Code empowers a secured creditor to sell collateral. This power is circumscribed. A secured party may not sell before default. A secured party cannot self-deal in a private sale. A pledgee of securities can sell to itself in a private sale if the securities are of a kind that is customarily sold on a recognized market, but the law is unclear what formalities the pledgee must meet to memorialize the sale. A secured party may not sell in a commercially reasonable manner to a buyer with notice of the commercial unreason. This article explores …

Evaluating Large Delay Estimation Techniques For Assisted Living Environments, Swarnadeep Bagchi, Ruairí De Fréin

Articles

Abstract Phase wraparound due to large inter-sensor spacings in multi-channel demixing limits the range of relative delays that many time–frequency relative delay estimators can estimate. The performance of a large relative delay estimation method, called the elevatogram, is evaluated in the presence of significant phase wraparound. This paper compares the elevatogram with the popular relative delay estimator used in DUET and the brute-force approach in D-AdRess and analyses its computational efficiency. The elevatogram can accurately estimate relative delays of speech signals of up to 800 samples, whereas DUET and D-AdRess were limited to delays of 7 and 35 samples, given …

Visual Attention For Linguistic And Non-Linguistic Body Actions In Non-Signing And Native Signing Children, Rain G. Bosworth, So One Hwang, David P. Corina

Articles

Evidence from adult studies of deaf signers supports the dissociation between neural systems involved in processing visual linguistic and non-linguistic body actions. The question of how and when this specialization arises is poorly understood. Visual attention to these forms is likely to change with age and be affected by prior language experience. The present study used eye-tracking methodology with infants and children as they freely viewed alternating video sequences of lexical American sign language (ASL) signs and non-linguistic body actions (self-directed grooming action and objectdirected pantomime). In Experiment 1, we quantified fixation patterns using an area of interest (AOI) approach …

A Framework For Sexism Detection On Social Media Via Byt5 And Tabnet, Arjumand Younus, Muhammad Atif Qureshi

Articles

Hateful and offensive content on social media platforms particularly content directed towards a specific gender is a great impediment towards equality, diversity and inclusion. Social media platforms are facing increasing pressure to work towards regulation of such content; and this has directed researchers in text mining to work towards hate speech identification algorithms. One such attempt is sexism detection for which mostly transformer-based text methods have been proposed. We propose a combination of byte-level model ByT5 with tabular modeling via TabNet that has at its core an ability to take into account platform and language aspects of the challenging task …

Relational Justice And Relational Pedagogy In Professional Social Care Work, Niall Hanlon

Articles

The principle of social justice is central to the newly regulated profession of Social Care Worker [SCW] in Ireland and the language of social justice features in the Standards of Proficiency [SoP] and Code of Professional Conduct and Ethics [CPCE]. This is very welcome given the history of institutional neglect and abuse in Irish social care. However, social care work in Ireland lacks a tradition of social justice in theory and practice, and policy is generally couched in minimalist terms of individual civil and political rights, equality of opportunity, and non-discrimination and is heavily focused on protection and risk management. …

Dialogue Policies For Confusion Mitigation In Situated Hri, Na Li, Robert J. Ross

Articles

Confusion is a mental state triggered by cognitive disequilibrium that can occur in many types of task-oriented interaction, including Human-Robot Interaction (HRI). People may become confused while interacting with robots due to communicative or even task-centred challenges. To build a smooth and engaging HRI, it is insufficient for an agent to simply detect confusion; instead, the system should aim to mitigate the situation. In light of this, in this paper, we present our approach to a linguistic design of dialogue policies to build a dialogue framework to alleviate interlocutor confusion. We also outline our sketch and discuss challenges with respect …

What Is A Metaphorical Collocation?, Jakob Patekar

Articles

In research on collocations published in English we encounter, albeit rarely, the use of the notion “metaphorical collocations”. It is interesting to note that seldom if ever are metaphorical collocations defined in any way in these studies, suggesting that researchers find the term self-explanatory. However, seeing that metaphorical collocations are an exciting area of research that is yet to draw attention from the wider community ofresearchers, the aim of this paper is to analyze the current understanding of what a metaphorical collocation is by examining the theoretical foundations as well as studies, specifically those published in English (as the language …

Devotee/Ethnographer: My Struggle At The Boundary Walls Of Participant Observation, Atreyee Majumder

Articles

This article demonstrates the difficulty of incorporating within the methodological ambit of ‘participant observation’, a possibility of the ethnographer herself staking claim in the religious truth claims of the community that constitute the subject of research. In so doing, this article provides a critique of the concept of participant observation to point out that participant observation anticipates the work of the ethnographer in participating in the physical, performative lives of the community that she purports to study, but never the internal life, especially the life of accessing a register of truth. I found myself in a curious situation as a …

Ideas, Power And Agency: Policy Actors And The Formulation Of Language-In-Education Policy For Multilingualism, Susanna Nocchi, Iker Erdocia, Mary Ruane

Articles

The processes of formulation of language policies have not been researched thoroughly. This paper aims to explore the relationship between ideas, power and agency in language policy-making and specifically with reference to the formulation of language-in-education policy for multilingualism in Ireland. Through an argumentative approach to language policy and using a discursive institutionalist framework, the paper examines data from policy documents and interviews with policy actors in the Department of Education and Skills. The paper reports on the ways in which agentive discourses are constrained and enabled by institutional structures. The analysis shows how power resulting from asymmetric internal forces …

Square Pegs And Round Holes: Differentiated Instruction And The Law Classroom, Karen J. Sneddon

Articles

As the academic semester begins, law students enter the classroom with sharpened pencils and charged laptops. Law professors enter the classroom with prepared notes and tabbed casebooks. But how will law professors ensure that the learning of each individual student is supported? Students do not take one path to law school. From English majors to engineering majors, students enter law school immediately upon graduating from college or years after graduation with various professional experiences. Despite criticism that legal education is resistant to change and over-relies on the Socratic Method, law school educators know that learning is not a one-size-fits-all experience. …

Improving Interpreters’ Normative Ethics Discourse By Imparting Principled-Reasoning Through Case Analysis, Robyn K. Dean, Robert Q. Pollard Jr.

Articles

The vocabulary available to community interpreters regarding professional ethics is typically limited to a set of prohibitions—what interpreters should not do. These prohibitions are disproportionately more prevalent in ethical documents and discourse than guidance on what interpreters should do. Both types of guidance are examples of normative ethical messages. However, when interpreters are asked to justify decisions which lead to them taking action rather than refraining from action, they are left with insufficient vocabulary to do so. Without a broader normative vocabulary allowing conversation regarding action-taking, interpreters tend to rely on unhelpful, non-normative language such as metaphors which fail to …

Ethnicity, Self-Knowledge And Literary Sensitivity: A Sociological Reading Of V. S. Naipaul’S First Four Novels, N. Jayaram

Articles

Taking a cue from G. S. Ghurye’s Shakespeare on Conscience and Justice (1965) this lecture in his memory explores the role of ethnicity in shaping the selfknowledge and literary sensitivity of V. S. Naipaul. Naipaul’s life traverses three distinct cultures: the Hindu culture brought by his ancestors who came as indentured migrants to Trinidad, the Creole culture of colonial Trinidad and the emerging modern culture of western civilisation. Much of Naipaul’s self-knowledge involved his engagement with these three cultures and his experience of the interplay between colonialism and ethnicity. In his first four novels—Miguel Street, The Mystic Masseur, The Suffrage …

Procedural Losses And The Pyrrhic Victory Of Abolishing Qualified Immunity, Adam A. Davidson

Articles

Who decides? Failing to consider this simple question could turn attempts to abolish qualified immunity into a Pyrrhic victory. That is because removing qualified immunity does not change the answer to this question; the federal courts will always decide. For an outcome-neutral critic of qualified immunity who cares only about its doctrinal failures, this does not matter. But for the vast majority of critics who are outcome- sensitive, meaning they care about qualified immunity because of its role in police accountability, this is a troubling realization. Building on earlier work on the equilibration thesis, as well as on qualitative and …

Exploring Pedagogic And Practical Intersections Of Academic Writing Support For Students In Higher Education, Maria-Jose Gonzalez, Roisin Donnelly

Articles

This case study explores undergraduate and postgraduate student perceptions of the nature and effectiveness of academic writing provision and practice in a university in Ireland. Its focus isthe Academic Writing Centre (AWC), a university-wide initiative to support all students. It discusses students’ perceptions as to the academic writing support provided at the AWC and students’ preferred writing strategies. The research design used a qualitative approach to gather data on students’ perceptions of the academic writing support received at one-to-one consultations. Data was gathered via a student survey (n=21) sent to all students who avail of the AWC’s one-to-one support. Findings …

Police Agencies On Facebook Overreport On Black Suspects, Ben Grunwald, Julian Nyarko, John Rappaport

Articles

A large and growing share of the American public turns to Facebook for news. On this platform, reports about crime increasingly come directly from law enforcement agencies, raising questions about content curation. We gathered all posts from almost 14,000 Facebook pages maintained by US law enforcement agencies, focusing on reporting about crime and race. We found that Facebook users are exposed to posts that overrepresent Black suspects by 25 percentage points relative to local arrest rates. This overexposure occurs across crime types and geographic regions and increases with the proportion of both Republican voters and non-Black residents. Widespread exposure to …

Articles

This is a case study of Faculty perceptions of the nature and effectiveness of academic writing provision and practice in a university in Ireland. It is presented in tandem with a case study of student persecptions from an Academic Writing Centre and taken together, both discuss the pedagogical approach adopted by the two pan-university initiatives. The focus of this case study is a Professional Development module for Faculty designed with a dual purpose - to support them to develop their own professional writing for publication, and enabling them to use the same strategies to support and reinforce their students’ academic …

Investigating How Speech And Animation Realism Influence The Perceived Personality Of Virtual Characters And Agents, Sean A. Thomas, Ylva Ferstl, Rachel Mcdonnell, Cathy Ennis

Articles

The portrayed personality of virtual characters and agents is understood to influence how we perceive and engage with digital applications. Understanding how the features of speech and animation drive portrayed personality allows us to intentionally design characters to be more personalized and engaging. In this study, we use performance capture data of unscripted conversations from a variety of actors to explore the perceptual outcomes associated with the modalities of speech and motion. Specifically, we contrast full performance-driven characters to those portrayed by generated gestures and synthesized speech, analysing how the features of each influence portrayed personality according to the Big …

Shapley Idioms: Analysing Bert Sentence Embeddings For General Idiom Token Identification, Vasudevan Nedumpozhimana, Filip Klubicka, John Kelleher

Articles

This article examines the basis of Natural Language Understanding of transformer based language models, such as BERT. It does this through a case study on idiom token classification. We use idiom token identification as a basis for our analysis because of the variety of information types that have previously been explored in the literature for this task, including: topic, lexical, and syntactic features. This variety of relevant information types means that the task of idiom token identification enables us to explore the forms of linguistic information that a BERT language model captures and encodes in its representations. The core of …

Whither The Lofty Goals Of The Environmental Laws?: Can Statutory Directives Restore Purposivism When We Are All Textualists Now?, Stephen M. Johnson

Articles

Congress set ambitious goals to protect public health and the environment when it enacted the federal environmental laws through bipartisan efforts in the 1970s. For many years, the federal courts interpreted the environmental laws to carry out those enacted purposes. Over time, however, courts greatly reduced their focus on the environmental and public health purposes of the environmental laws when interpreting those statutes due to the rise in textualism, the declining influence of the Chevron doctrine, and the increasing willingness of courts to defer to agency underenforcement of statutory responsibilities across all regulatory statutes.

In 2020, the Environmental Protection Network, …

The Hidden Harms Of Privacy Penalties, Mary D. Fan

Articles

How to frame privacy penalties to protect our personal information is an important question as demands for legislation and proposals proliferate. The predominant assumption in calls for a comprehensive consumer privacy regime is that regulation and penalties arm the consumer David against Goliath businesses. Missing in the focus on powerful companies is attention to the potential harms of expanding privacy penalties for small-fry individuals and entities, especially from disfavored or marginalized groups. This article is the first to illuminate the regressive risks of privacy penalties, showing how broad privacy penalties can become tools for harassment of small businesses and individuals …

Human Mental Workload: A Survey And A Novel Inclusive Definition, Luca Longo, Christopher D. Wickens, Gabriella Hancock, P.A. Hancock

Articles

Human mental workload is arguably the most invoked multidimensional construct in Human Factors and Ergonomics, getting momentum also in Neuroscience and Neuroergonomics. Uncertainties exist in its characterization, motivating the design and development of computational models, thus recently and actively receiving support from the discipline of Computer Science. However, its role in human performance prediction is assured. This work is aimed at providing a synthesis of the current state of the art in human mental workload assessment through considerations, definitions, measurement techniques as well as applications, Findings suggest that, despite an increasing number of associated research works, a single, reliable and …

Examining The Size Of The Latent Space Of Convolutional Variational Autoencoders Trained With Spectral Topographic Maps Of Eeg Frequency Bands, Taufique Ahmed, Luca Longo

Articles

Electroencephalography (EEG) is a technique of recording brain electrical potentials using electrodes placed on the scalp [1]. It is well known that EEG signals contain essential information in the frequency, temporal and spatial domains. For example, some studies have converted EEG signals into topographic power head maps to preserve spatial information [2]. Others have produced spectral topographic head maps of different EEG bands to both preserve information in The associate editor coordinating the review of this manuscript and approving it for publication was Ludovico Minati . the spatial domain and take advantage of the information in the frequency domain [3]. …
