An Investigation Of The Role Of Spatial Ability In Representing And Solving Word Problems Among Engineering Students, Gavin Duffy, Sheryl A. Sorby, Brian Bowe

Articles

Background

Spatial ability is significantly related to performance in engineering education. Problem solving, an activity that is highly relevant to engineering education, has been linked to spatial ability.

Purpose/Hypothesis

To what extent is spatial ability related to problem solving among engineering students and how do approaches to problem representation and solution vary with spatial ability level?

Design/Method

Three instruments – a spatial ability test, word math problems and accompanying core math competency questions – were administered to two samples of first year engineering students in two different countries. Data were analyzed at the test level to evaluate the relationship of …

English Word And Pseudoword Spellings And Phonological Awareness: Detailed Comparisons From Three L1 Writing Systems, Katherine I. Martin, Emily Lawson, Kathryn Carpenter, Elisa Hummer

Articles

Spelling is a fundamental literacy skill facilitating word recognition and thus higher level reading abilities via its support for efficient text processing (Adams, 1990; Joshi et al., 2008; Perfetti and Stafura, 2014). However, relatively little work examines second language (L2) spelling in adults, and even less work examines learners from different first language (L1) writing systems. This is despite the fact that the influence of L1 writing system on L2 literacy skills is well documented (Hudson, 2007; Koda and Zehler, 2008; Grabe, 2009). To address this shortcoming, this study collected data on real word spelling, pseudoword spelling, and phonological awareness …

Audio-Visual Caption Evaluation Metric For People Who Are Deaf And Hard Of Hearing, Akhter Al Amin

Articles

While the availability of captioned television programming has increased, the quality of this captioning is not always acceptable to Deaf and Hard of Hearing (DHH) viewers, especially for live or unscripted content, broadcast from local television stations, especially in smaller markets. There is a need for formal metrics to evaluate captioning quality, to enable audits or quality assurance. Although some current caption metrics focus on comparing the textual accuracy (comparing the caption text and accurate transcription of what was spoken), there are other properties of captions that may affect quality or usability judgments. We propose to conduct experiments with DHH …

An Empirical Investigation Of The Relationship Between Business Performance And Suicide In The Us, Rawayda Abdou, Damien Cassells, Jenny Berrill, Jim Hanly

Articles

Previous research suggests that mortality rates behave pro-cyclically with respect to economic growth, with suicides representing a notable exception that consistently increase in economic downturns. Over recent years, there is ample evidence in the literature that the working environment in the US has deteriorated significantly, suggesting that suicide rates may not necessarily behave in a counter-cyclical manner with business performance. Utilising recent suicide data, this study empirically tests the hypothesis that adverse working conditions over recent years may have resulted in a pro-cyclical relationship between business performance and suicide. Unlike previous studies, we use a stock market index, a leading …

A Sentence Need Not Begin With A Capital Letter, Jakob Patekar

Articles

This paper examines the challenge of starting a sentence with a proper noun or an abbreviation that is written with an initial lowercase letter (e.g. iPhone, danah boyd, pH). Traditionally, placing such words at the beginning of a sentence would be avoided, but this limits one's syntax and style. Hence, the aim of this paper is to explore the rules and practices of writing certain proper nouns and abbreviations with a lowercase letter and starting a sentence with such words in Croatian and English. Therefore, we reviewed the rules and guidelines in orthography handbooks and style guides, analyzed the corpora …

Minds Without Spines: Evolutionarily Inclusive Animal Ethics., Irina Mikhalevich, Russell Powell

Articles

Invertebrate animals are frequently lumped into a single category and denied welfare protections despite their considerable cognitive, behavioral, and evolutionary diversity. Some ethical and policy inroads have been made for cephalopod molluscs and crustaceans, but the vast majority of arthropods, including the insects, remain excluded from moral consideration. We argue that this exclusion is unwarranted given the existing evidence. Anachronistic readings of evolution, which view invertebrates as lower in the scala naturae, continue to influence public policy and common morality. The assumption that small brains are unlikely to support cognition or sentience likewise persists, despite growing evidence that arthropods have …

Disaggregating Ineffective Assistance Of Counsel Doctrine: Four Forms Of Constitutional Ineffectiveness, Eve Brensike Primus

Articles

For years, experts have blamed Strickland v. Washington’s lax standard for assessing trial attorney effectiveness for many of the criminal justice system’s problems. But the conventional understanding of Strickland as a problem for ineffectiveness claims gives the decision too much prominence because it treats Strickland as the test for all such claims. That is a mistake. Properly understood, the Supreme Court has recognized four different constitutional forms of trial attorney ineffectiveness, and Strickland’s two pronged test applies to only one of the four. If litigants and courts would notice this complexity and relegate Strickland to its proper place, it would …

Commonsense Consent, Roseanna Sommers

Articles

Consent is a bedrock principle in democratic society and a primary means through which our law expresses its commitment to individual liberty. While there seems to be broad consensus that consent is important, little is known about what people think consent is. This Article undertakes an empirical investigation of people’s ordinary intuitions about when consent has been granted. Using techniques from moral psychology and experimental philosophy, it advances the core claim that most laypeople think consent is compatible with fraud, contradicting prevailing normative theories of consent. This empirical phenomenon is observed across over two dozen scenariosspanning numerous contexts in which …

Asynchronous Assistance: A Social Network Analysis Of Influencing Peer Interactions In Peerwise, Tomas Shields, Geraldine Gray, Barry J. Ryan

Articles

This mixed methods, investigative case study explored student patterns of use within the online PeerWise platform to identify the most influencing activities and to build a model capable of predicting performance based on these influencing activities. Peerwise is designed to facilitate student peer-to-peer engagement through creating, answering and ranking multiple choice questions; this study sought to understand the relationship between student engagement in Peerwise and learning performance. To address the research question, various usage metrics were explored, visualized and modelled, using social network analysis with Gephi, Tableau and Python. These findings were subsequently analyzed in light of the qualitative survey …

The Eighth Amendment Power To Discriminate, Kathryn E. Miller

Articles

For the last half-century, Supreme Court doctrine has required that capital jurors consider facts and characteristics particular to individual defendants when determining their sentences. While liberal justices have long touted this individualized sentencing requirement as a safeguard against unfair death sentences, in practice the results have been disappointing. The expansive discretion that the requirement confers on overwhelmingly White juries has resulted in outcomes that are just as arbitrary and racially discriminatory as those that existed in the years before the temporary abolition of the death penalty in Furman v. Georgia.' After decades of attempting to eliminate the requirement, conservative justices …

An Application Of Machine Learning To Explore Relationships Between Factors Of Organisational Silence And Culture, With Specific Focus On Predicting Silence Behaviours, Stephen Barrett Dr

Articles

Research indicates that there are many individual reasons why people do not speak up when confronted with situations that may concern them within their working environment. One of the areas that requires more focused research is the role culture plays in why a person may remain silent when such situations arise. The purpose of this study is to use data science techniques to explore the patterns in a data set that would lead a person to engage in organisational silence. The main research question the thesis asks is: Is Machine Learning a tool that Social Scientists can use with respect …

The Grammatical Class Effect Is Separable From The Concreteness Effect In Language Learning, Katherine I. Martin, Natasha Tokowicz

Articles

Typically concrete words are learned better than abstract words (Kaushanskaya & Rechtzigel, 2012), and nouns are learned better than verbs (Kauschke & Stenneken, 2008). However, most studies on concreteness have not manipulated grammatical class (and vice versa), leaving the relationship between the two unclear. Therefore, in two experiments we examined the effects of grammatical class and concreteness simultaneously in foreign language vocabulary learning. In Experiment 1, English speakers learned ‘foreign language’ words (English pseudowords) mapped to concrete and abstract nouns and verbs. In Experiment 2, English speakers learned German words with the same procedure. Overall, the …

Commensality And Connection: How Shared Food Experiences Connect Characters In Philip Pullmans His Dark Materials, The Book Of Dust And ‘Lyra’ Stories, Susan Anna Grace

Articles

Commensality is an inherently social activity that shapes society and enacts social dynamics. Consequently, these shared exchanges can reveal much about the society and the individuals who engage in the act. This thesis explores commensality in Philip Pullman’s His Dark Materials trilogy, The Book of Dust Series and companion texts to the novels. The research investigates how commensal exchanges create and maintain connections between characters across the collection. In doing so, it considers how literary characters differ from real-life humans and how the existing body of knowledge on commensality can be applied to literary figures. A qualitative approach was …

Theory Of The Nudnik: The Future Of Consumer Activism And What We Can Do To Stop It, Yonathan A. Arbel, Roy Shapira

Articles

How do consumers hold sellers accountable and enforce market norms? This Article contributes to our understanding of consumer markets in three ways. First, the Article identifies the role of a small subset of consumers-the titular "nudniks"-as engines of market discipline. Nudniks are those who call to complain, speak with managers, post online reviews, and file lawsuits. Typified by an idiosyncratic utility function and certain unique personality traits, nudniks pursue action where most consumers remain passive. Although derided in courtrooms and the court of public opinion, we show that nudniks can solve consumer collective action problems, leading to broad market improvements. …

Undergraduate Textbook Representations Of Meiosis Neglect Essential Elements, Leslie Kate Wright, Grace Elizabeth C. Dy, Dina L. Newman

Articles

The process of meiosis is an essential topic that secondary and postsecondary students struggle with. The important meiosis-related concepts of homology, ploidy, and segregation can be described using the DNA Triangle framework, which connects them to the multidimensional nature of DNA (chromosomal, molecular, and informational levels). We have previously established that undergraduate biology students typically fail to describe and/or link appropriate levels to their explanations of meiosis. We hypothesize that students' understanding mirrors the resources they are given – in other words, textbook figures often lack many of the important connections that experts include when talking about meiosis. Prior work …

Rethinking Foster Care: Why Our Current Approach To Child Welfare Has Failed, Vivek Sankaran, Christopher Church

Articles

Over the past decade, the child welfare system has expanded, with vast public and private resources being spent on the system. Despite this investment, there is scant evidence suggesting a meaningful return on investment. This Article argues that without a change in the values held by the system, increased funding will not address the public health problems of child abuse and neglect.

Assessing The Sustainability Implications Of Autonomous Vehicles: Recommendations For Research Community Practice, Eric Williams, Vivekananda Das, Andrew Fisher

Articles

Autonomous vehicles (AV) are poised to induce disruptive changes, with significant implications for the economy, the environment, and society. This article reviews prior research on AVs and society, and articulates future needs. Research to assess future societal change induced by AVs has grown dramatically in recent years. The critical challenge in assessing the societal implications of AVs is forecasting how consumers and businesses will use them. Researchers are predicting the future use of AVs by consumers through stated preference surveys, finding analogs in current behaviors, utility optimization models, and/or staging empirical “AV-equivalent” experiments. While progress is being made, it is …

Consumer Psychology And The Problem Of Fine Print Fraud, Roseanna Sommers, Meirav Furth-Matzkin

Articles

This Article investigates consumers' beliefs about contracts that are formed as a result of fraud. Across four studies, we asked lay survey respondents to judge scenarios in which sellers use false representations to induce consumers to buy products or services. In each case, the false representations are directly contradicted by the written terms of the contract, which the consumers sign without reading. Our findings reveal that lay respondents, unlike legally trained respondents, believe that such agreements are consented to and will be enforced as written, despite the seller's material deception. Importantly, fine print discourages consumers from wanting to take legal …

Exploring Attitudes And Reactions To Unfamiliar Food Pairings: An Examination Of The Underlying Motivations And The Impact Of Culinary Education, Mark Traynor, Andrew Moreo, Lisa Cain, Roisin Burke, Catherine Barry-Ryan

Articles

A mixed-methodology study was conducted to better understand consumer attitudes and behaviors toward novel food pairings and the impact of culinary education. Focus groups were conducted to investigate the underlying motivational factors to the reactions and behaviors toward unfamiliar foods. The second phase of the study consisted of sensory evaluation by two separate cohorts, panelists with and without culinary education, of food products created through the novel pairings of foods. Panelists with culinary education expressed a greater overall liking for the animal-based pairing. Sensory-Affective and Ideational factors appeared to be underlying motivational factors of these hedonic reactions.

Artificial Intelligence & Machine Learning: A Model For A New Judicial System?, Paula C. Arias

Articles

Artificial Intelligence and Machine Learning are a result not only of technological advances but also of the exploitation of information or data, which has led to its expansion into almost all aspects of modern life, including law and its practice. Due to the benefits of these technologies, such as efficiency, objectivity, and transparency, the trend is towards the integration of Artificial Intelligence and Machine Learning in the judicial system. Integration that is advocated at all levels and, today, has been achieved mostly under the implementation of tools to assist the exercise of the judiciary. The «success» of this integration has …

In Their Shoes: A Structured Analysis Of Job Demands, Resources, Work Experiences, And Platform Commitment Of Crowdworkers In China, Yihong Wang, Konstantinos Papangelis, Ioanna Lykourentzou, Hai-Ning Liang, Irwyn Sadien, Evangelia Demerouti, Vassilis-Javed Khan

Articles

Despite the growing interest in crowdsourcing, this new labor model has recently received severe criticism. The most important point of this criticism is that crowdworkers are often underpaid and overworked. This severely affects job satisfaction and productivity. Although there is a growing body of evidence exploring the work experiences of crowdworkers in various countries, there have been a very limited number of studies to the best of our knowledge exploring the work experiences of Chinese crowdworkers. In this paper we aim to address this gap. Based on a framework of well-established approaches, namely the Job Demands-Resources model, the Work Design …

Delivering Gender Justice In Academia Through Gender Equality Plans? Normative And Practical Challenges, Sara Clavero, Yvonne Galligan

Articles

This paper employs the concept of epistemic justice to examine the potential for gender equality plans (GEPs) to bring about sustainable transformative change towardsgender equality in higher education. Mindful of both the limitationsand opportunitiesof gender policy interventions,the paper highlights the importance of approaching gender inequality as a problem of justice and power rather than asan issueof “loss of talent.”The paper drawson Fricker's account of epistemic justice as well ason Bourdieu's analysis of power in the academic field, to evaluate seven GEPs in European universities for their potential to transform gender–power relations in academia.

A Conceptual Framework For Digital Civics Pedagogy Informed By The Philosophy Of Information, Estelle Clements

Articles

Purpose – The purpose of this paper is to draw on the philosophy of information, specifically the work of Luciano Floridi, to argue that digital civics must fully comprehend the implications of the digital environment, and consequently an informational ontology, to deliver to students an education that will prepare them for full participation as citizens in the infosphere.

Design/methodology/approach – Introducing this philosophy for use in education, the research discusses the ethical implications of ontological change in the digital age; informational organisms and their interconnectivity; and concepts of agency, both organic and artificial in digitally mediated civic interactions and civic …

Expectations Of Artificial Intelligence And The Performativity Of Ethics: Implications For Communication Governance, Aphra Kerr, Marguerite Barry, John D. Kelleher

Articles

This article draws on the sociology of expectations to examine the construction of expectations of ‘ethical AI’ and considers the implications of these expectations for communication governance. We first analyse a range of public documents to identify the key actors, mechanisms and issues which structure societal expectations around artificial intelligence (AI) and an emerging discourse on ethics. We then explore expectations of AI and ethics through a survey of members of the public. Finally, we discuss the implications of our findings for the role of AI in communication gover- nance. We find that, despite societal expectations that we can design …

The Wild Atlantic Way: A Tourism Journey, Kevin A. Griffin, Gerard Dunne

Articles

The Wild Atlantic Way is possibly the most celebrated, high profile tourism initiative to be launched in Ireland in recent years. It consists of a defined touring route along the western seaboard, one of the most scenic, remote, and sensitive stretches of Irish landscape. This paper presents the principal findings from a survey of 341 tourism and hospitality product providers along the Wild Atlantic Way. The main aim of the research was to investigate the perceived impacts (economic, environmental, and socio-cultural) of this new tourism initiative on the local areas through which it passes. The results paint a generally positive …

Distancing Refugees, Geoffrey Heeren

Articles

Today, two systems exist for addressing the humanitarian claims of persons fleeing persecution. One system consists of refugees living in host countries, often in large camps, who ideally are then resettled in other countries or repatriated when it is safe to do so. The other system involves refugees arriving in a country and seeking asylum-a right with ancient religious roots. The first "encampment model" is fundamentally broken, as most refugees are housed in the developing or least developed world in terrible conditions for extended periods of time, with little or no realistic hope of resettlement elsewhere or repatriation. The developed …

Identity: Obstacles And Openings, Osamudia R. James

Articles

Progress regarding equality and social identities has moved in a bipolar fashion: popular engagement with the concept of social identities has increased even as courts have signaled decreasing interest in engaging identity. Maintaining and deepening the liberatory potential of identity, particularly in legal and policymaking spheres, will require understanding trends in judicial hostility toward "identity politics," the impact of status hierarchy even within minoritized identity groups, and the threat that white racial grievance poses to identitarian claims.
