A simple review by a linguist, citing many articles by physicists: Quantitative methods, agent-based computer simulations, language dynamics, language typology, historical linguistic

BlenX-based compositional modeling of complex reaction mechanisms

Molecular interactions are wired in a fascinating way resulting in complex behavior of biological systems. Theoretical modeling provides a useful framework for understanding the dynamics and the function of such networks. The complexity of the biological networks calls for conceptual tools that manage the combinatorial explosion of the set of possible interactions. A suitable conceptual tool to attack complexity is compositionality, already successfully used in the process algebra field to model computer systems. We rely on the BlenX programming language, originated by the beta-binders process calculus, to specify and simulate high-level descriptions of biological circuits. The Gillespie's stochastic framework of BlenX requires the decomposition of phenomenological functions into basic elementary reactions. Systematic unpacking of complex reaction mechanisms into BlenX templates is shown in this study. The estimation/derivation of missing parameters and the challenges emerging from compositional model building in stochastic process algebras are discussed. A biological example on circadian clock is presented as a case study of BlenX compositionality

What is India speaking? Exploring the "Hinglish" invasion

© 2016 Elsevier B.V. All rights reserved. Language competition models help understand language shift dynamics, and have effectively captured how English has outcompeted various local languages, such as Scottish Gaelic in Scotland, and Mandarin in Singapore. India, with a 125 million English speakers boasts the second largest number of English speakers in the world, after the United States. The 1961-2001 Indian censuses report a sharp increase in Hindi/English Bilinguals, suggesting that English is on the rise in India. To the contrary, we claim supported by field evidence, that these statistics are inaccurate, ignoring an emerging class who do not have full bilingual competence and switch between Hindi and English, communicating via a code popularly known as "Hinglish". Since current language competition models oc clude hybrid practices and detailed local ecological factors, they are inappropriate to capture the current language dynamics in India. Expanding predator-prey and sociolinguistic theories, we draw on local Indian ecological factors to develop a novel three-species model of interaction between Monolingual Hindi speakers, Hindi/English Bilinguals and Hinglish speakers, and explore the long time dynamics it predicts. The model also exhibits Turing instability, which is the first pattern formation result in language dynamics. These results challenge traditional assumptions of English encroachment in India. More broadly, the three-species model introduced here is a first step towards modeling the dynamics of hybrid language scenarios in other settings across the world

Society, languages and ideologies in the Oasis of Siwa (Egypt): listening to people’s voices

The present thesis proposes a linguistic ethnography of the oasis of Siwa, an Amazigh enclave situated in the Western Egyptian desert. De facto independent for centuries, it is only during the 20th century that this area started undergoing processes of modernization and Arabization with a consequent inclusion in the national (Egyptian) and the international (Amazigh) arenas. Although representing an interesting field for sociolinguistic research, this subject has not attracted scholarly attention so far and this work is a first attempt to fill that gap. This research has a multidisciplinary approach built on sociolinguistic and linguistic anthropological theories. It falls into the field of language attitudes and ideologies’ studies, and it developed a combined method including ethnographic interviewing and participant observation. The thesis presents the dynamics of language use within the oasis from an insider perspective and discusses the mechanisms and the ideologies underlying both speakers’ practices and attitudes, arguing that the emerging differentiation of linguistic practices is related to the attitudinal variation across specific social categories, which adhere to different ideologies. The study portrays a multiform community in a phase of socio-economic transition and sociolinguistic change in progress

Child language brokers’ representations of parent-child relationships

This paper reports the analysis of qualitative data from a broader study of young people’s representations of conflicting roles in child development. Just over a quarter of the group, bilingual students who spoke a variety of first languages, had had personal experience of child language brokering (CLB). Employing vignette methodology, they were invited to reflect on the implications of an adolescent boy’s language brokering activities for, among other things, his relationships within his family. In this paper we will present brief case studies to illustrate different positions that members of the group adopted in relation to developmental scripts emphasizing independence and interdependence between young people and their parents (Dorner et al. 2008). Through an analysis of individual CLB case studies, we illustrate various ways in which individual young people reported the balancing of the demands of autonomy and connectedness in their analysis of relationships between young people and their parents

Early Childhood Development and the Law

Early childhood development is a robust and vibrant focus of study in multiple disciplines, from economics and education to psychology and neuroscience. Abundant research from these disciplines has established that early childhood is critical for the development of cognitive abilities, language, and psychosocial skills, all of which turn, in large measure, on the parent-child relationship. And because early childhood relationships and experiences have a deep and lasting impact on a child’s life trajectory, disadvantages during early childhood replicate inequality. Working together, scholars in these disciplines are actively engaged in a national policy debate about reducing inequality through early childhood interventions. Despite the vital importance of this period, the law and legal scholars have been largely indifferent to the dynamics of early childhood development. Doctrine and legislation are rarely developmentally sensitive, lumping children into an undifferentiated category regardless of age. The legal system thus misses key opportunities to combat inequality and foster healthy development for all children. And most legal scholars do not engage with the wealth of interdisciplinary research on early childhood, nor are they part of the interdisciplinary dialogue and policy debates. As a result, that conversation does not include the voices of lawyers and legal scholars, who are uniquely positioned to add critical insights. Remedying this stark disconnect requires doing for law what scholars have done in other disciplines: creating a distinctive field. Accordingly, this Article proposes a subdiscipline of early childhood development and the law. The new field crystallizes a distinctive interest that the legal system must attend to and charts a path for legal scholars to follow for years to come. As with the dawning of fields such as juvenile justice, domestic violence, and elder law, early childhood development and the law will be a focal point for research within the legal academy, a vital bridge to scholars in other disciplines, and an important means for bringing lawyers and legal scholars to the heart of emerging policy debates

Qualitative Analysis of the Interdisciplinary Interaction between Data Analysis Specialists and Novice Clinical Researchers

Background: The inherent complexity of statistical methods and clinical phenomena compel researchers with diverse domains of expertise to work in interdisciplinary teams, where none of them have a complete knowledge in their counterpart's field. As a result, knowledge exchange may often be characterized by miscommunication leading to misinterpretation, ultimately resulting in errors in research and even clinical practice. Though communication has a central role in interdisciplinary collaboration and since miscommunication can have a negative impact on research processes, to the best of our knowledge, no study has yet explored how data analysis specialists and clinical researchers communicate over time. Methods/Principal Findings: We conducted qualitative analysis of encounters between clinical researchers and data analysis specialists (epidemiologist, clinical epidemiologist, and data mining specialist). These encounters were recorded and systematically analyzed using a grounded theory methodology for extraction of emerging themes, followed by data triangulation and analysis of negative cases for validation. A policy analysis was then performed using a system dynamics methodology looking for potential interventions to improve this process. Four major emerging themes were found. Definitions using lay language were frequently employed as a way to bridge the language gap between the specialties. Thought experiments presented a series of ""what if'' situations that helped clarify how the method or information from the other field would behave, if exposed to alternative situations, ultimately aiding in explaining their main objective. Metaphors and analogies were used to translate concepts across fields, from the unfamiliar to the familiar. Prolepsis was used to anticipate study outcomes, thus helping specialists understand the current context based on an understanding of their final goal. Conclusion/Significance: The communication between clinical researchers and data analysis specialists presents multiple challenges that can lead to errors
