Network models of language provide a systematic way of linking cognitive processes to the structure and connectivity of language. Using network growth models to capture learning, we focus on the study of the emergence of complexity in early language learners. Specifically, we capture the emergent structure of young toddler’s vocabularies through network growth models assuming underlying knowledge representations of semantic and phonological networks. In construction and analyses of these network growth models, we explore whether phonological or semantic relationships between words (...) play a larger role in predicting network growth as these young learners add new words to their lexicon. We also examine how the importance of these semantic and phonological representations changes during the course of development. We propose a novel and significant theoretical framework for network growth models of acquisition and test the ability of these models to predict what words a specific child is likely to learn approximately one month in the future. We find that which acquisition model best fits is influenced by the underlying network representation, the assumed process of growth, and the network centrality measure used to relate the cognitive underpinnings of acquisition to network growth. The joint importance of representation, process, and the contribution of individual words to the predictive accuracy of the network model highlights the complex and multifaceted nature of early acquisition, provides new tools, and suggests experimental hypotheses for studying lexical acquisition.

This paper argues that “backstage” gallows humor among clinical mentors not only affects medical students’ perceptions of what it means to be a doctor but is also symptomatic and indicative of a much larger problem in medicine—namely, the failure to attend fully to the complexity and profundity of the lived experiences of illness, suffering, and death. Reorienting the discourse surrounding gallows humor away from whether or in what context it is acceptable and toward the reasons why doctors feel the need (...) to use such humor in the first place addresses this issue in a more illuminating way.

Recent efforts by legislative officials and public health advocates to reform the US food stamp program, or Supplemental Nutrition Assistance Program, have focused on restricting the types of foods eligible for purchase with SNAP benefits, specifically sugar-sweetened beverages. We argue that it is, in principle, permissible for the US government to enact a SNAP-specific SSB ban prohibiting the purchase of SSBs with SNAP benefits. While the government has a duty to ensure that citizens meet their nutritional needs, since SSBs provide (...) negligible nutrition, it has no obligation to subsidize them. Additionally, there is good reason to think that a SNAP-specific SSB ban would enable the government to better fulfill two other duties—improving citizens’ health and providing public services like Medicaid and Medicare in a more cost-effective manner. Still, because the costs and benefits of such a ban remain uncertain, we argue that the government should conduct well-designed pilot projects to help determine the effects of an SSB ban. (shrink)
In describing the foundations of our pedagogical approaches to service-learning, we seek to go beyond the navel-gazing—at times, paralyzing—paradoxes of neoliberal forces, which can do “good” for students and their communities, yet which also call students into further calculative frameworks for understanding the “value” of pre-health humanities education and social engagement. We discuss methods to create quiet forms of subversion that call for a moral imagination in extending an ethics of care to students as well as to the communities with (...) which they engage. While we recognize the partiality and limitations of our attempts, framing mentored service-learning in unexpected ways can help students and practitioners to understand their role within broader social, historical, cultural, and emotional contexts and encourage them to act intentionally toward the communities they seek to serve in response to this new self-knowledge. To that end, we outline an academically rigorous service-learning intervention at one of our universities. (shrink)
This paper makes a conceptual inquiry into the notion of ‘publics’, and forwards an understanding of this notion that allows more responsible forms of decision-making with regards to technologies that have localized impacts, such as wind parks, hydrogen stations or flood barriers. The outcome of this inquiry is that the acceptability of a decision is to be assessed by a plurality of ‘publics’, including that of a local community. Even though a plurality of ‘publics’ might create competing normative demands, its (...) acknowledgment is necessary to withstand the monopolization of the process of technology appraisal. The paper presents four ways in which such an appropriation of publicness takes place. The creation of dedicated ‘local publics’, in contrast, helps to overcome these problems and allows for more responsible forms of decision-making. We describe ‘local publics’ as those in which stakeholders from the different publics that are related to the process of technology implementation are brought together, and in which concerns and issues from these publics are deliberated upon. The paper will present eight conditions for increasing the effectiveness of such ‘local publics’. (shrink)
This paper presents an ethical approach to the use of lobbying within the context of the relationships among U.S. organizations, their lobbyists, and government officials. After providing a brief history of modern-day lobbying activities, lobbying is defined and described focusing on its role as a strategic marketing tool. Then ethical frameworks for understanding the impact of these practices on various external constituencies are delineated with an emphasis on the communitarian movement advanced by Etzioni. Consistent with the call for "informed advocacy" (...) by Laczniak (1993), the paper closes with an examination of the ethics of specific lobbying activities. (shrink)
To assess whether and how environmental values and sense of place relate to sustainable farming practices, we conducted a study in South Kona, Hawaii, addressing environmental values, sense of place, and farm sustainability in five categories: environmental health, community engagement and food security, culture and history, education and research, and economics. We found that the sense of place and environmental values indexes showed significant correlation to each category of sustainability in both independent linear regressions and multivariate regression. In total, sense (...) of place explained a larger share of the overall farm performance. However, each indicator showed relative strengths; environmental values showed significantly higher correlation to environmental and educational practices. Furthermore the scales were complimentary, and the use of both scales greatly improved prediction of good farming practices from a multiple-impact perspective. With implications for community and environmental impacts, results suggest that a more comprehensive view of farmers’ environmental values and place connections may help illuminate individual farmers’ decisions and sustainability-related practices.

Network science provides a set of quantitative methods to investigate complex systems, including human cognition. Although cognitive theories in different domains are strongly based on a network perspective, the application of network science methodologies to quantitatively study cognition has so far been limited in scope. This review demonstrates how network science approaches have been applied to the study of human cognition and how network science can uniquely address and provide novel insight on important questions related to the complexity of cognitive (...) systems and the processes that occur within those systems. Drawing on the literature in cognitive network science, with a focus on semantic and lexical networks, we argue three key points. Network science provides a powerful quantitative approach to represent cognitive systems. The network science approach enables cognitive scientists to achieve a deeper understanding of human cognition by capturing how the structure, i.e., the underlying network, and processes operating on a network structure interact to produce behavioral phenomena. Network science provides a quantitative framework to model the dynamics of cognitive systems, operationalized as structural changes in cognitive systems on different timescales and resolutions. Finally, we highlight key milestones that the field of cognitive network science needs to achieve as it matures in order to provide continued insights into the nature of cognitive structures and processes.

We consider Sussman et al. 's suggestion that auditory biases for processing low-noise relationships among pairs of acoustic variables is a preadaptation for human speech processing. Data from other animal communication systems, especially those involving sexual selection, also suggest that neural biases in the receiver system can generate strong selection on the form of communication signals.
Feminist scholarship on the relative importance of working-class institutional strength in the economy and in the state has led to two divergent conclusions. Radical feminists argue that working-class institutions dominated by men produce male-biased outcomes; socialist feminists hold that working-class institutions promote classwide interests that benefit women as well as men. This article addresses this debate by applying generic and gendered working-class strength models of the welfare state in an examination of women's public pension quality. Quality is measured as women's (...) average pension compared with that of men, relative to women's average earnings, and compared with the average wage in the society. The authors find support for the socialist feminist view. Working-class institutions, having historically organized and represented the interests of working men, benefit women by improving the security and adequacy of their retirement incomes, but it is women's access to working-class economic and political institutions that brings greater economic equality with men in old age.

The mining and energy industries present unique challenges to engineers, who must navigate sometimes competing responsibilities and codes of conduct, such as personal senses of right and wrong, professional ethics codes, and their employers’ corporate social responsibility policies. Corporate social responsibility is the current dominant framework used by industry to conceptualize firms’ responsibilities to their stakeholders, yet has it plays a relatively minor role in engineering ethics education. In this article, we report on an interdisciplinary pedagogical intervention in a petroleum (...) engineering seminar that sought to better prepare engineering undergraduate students to critically appraise the strengths and limitations of CSR as an approach to reconciling the interests of industry and communities. We find that as a result of the curricular interventions, engineering students were able to expand their knowledge of the social, rather than simply environmental and economic dimensions of CSR. They remained hesitant, however, in identifying the links between those social aspects of CSR and their actual engineering work. The study suggests that CSR may be a fruitful arena from which to illustrate the profoundly sociotechnical dimensions of the engineering challenges relevant to students’ future careers. (shrink)
