    Computational Sociolinguistics: A Survey

    Get PDF
    Language is a social phenomenon and variation is inherent to its social nature. Recently, there has been a surge of interest within the computational linguistics (CL) community in the social dimension of language. In this article we present a survey of the emerging field of "Computational Sociolinguistics" that reflects this increased interest. We aim to provide a comprehensive overview of CL research on sociolinguistic themes, featuring topics such as the relation between language and social identity, language use in social interaction and multilingual communication. Moreover, we demonstrate the potential for synergy between the research communities involved, by showing how the large-scale data-driven methods that are widely used in CL can complement existing sociolinguistic studies, and how sociolinguistics can inform and challenge the methods and assumptions employed in CL studies. We hope to convey the possible benefits of a closer collaboration between the two communities and conclude with a discussion of open challenges.Comment: To appear in Computational Linguistics.

    Survey and assessment of the design and evaluation techniques of cumulus cloud modification experiments for rain enhancement

    Get PDF
    Physical basis of cloud seeding and meteorological considerations involved in the efficient design of experiments for rain enhancement are discussed. An analysis of thevarious designs and statistical techniques currently being employed for evaluating the experiments is presented. The limitations of available statistical methods, when used alone, to establish significantly the changes in rainfall caused by cloud seeding within a reasonable period of experimentation are broughtout. The manner in which remarkable increase is produced in the power efficiency of some tests when applied along with the simultaneous measurements of physical covariates or predictor variables and proper stratification of data is elucidated. The scope of anlayses based on postfactum stratifications or partitioning of data and the problems of multiplicity of analyses are discussed

    A social forecast revisited

    Get PDF
    In 1971, the authors produced a 30-year forecast of leisure in the UK. In 2001 they obtained survey data for comparison with the forecasts. The paper presents the original forecasts and describes the methods used to produce them, assesses their accuracy in the light of the survey data, and concludes with some reflections on the underlying forecasting methodology and on changes in leisure patterns

    Survey of decentralized control methods

    Get PDF
    An overview is presented of the types of problems that are being considered by control theorists in the area of dynamic large scale systems with emphasis on decentralized control strategies. Approaches that deal directly with decentralized decision making for large scale systems are discussed. It is shown that future advances in decentralized system theory are intimately connected with advances in the stochastic control problem with nonclassical information pattern. The basic assumptions and mathematical tools associated with the latter are summarized, and recommendations concerning future research are presented

    Integrating survey and ethnographic methods to evaluate conditional cash transfer programs:

    Get PDF
    "Survey and ethnographic methods have been combined in the evaluations of conditional cash transfer (CCT) programs for the governments of Nicaragua and Turkey. This paper describes the quantitative and qualitative research designs for these evaluations, discusses the relative benefits of quantitative and qualitative approaches for studying CCTs, and provides examples of how findings of these different approaches complemented, explained, illuminated, or contradicted each other. While the surveys provided reliable measures of program impacts on human capital, the qualitative research provided explanations of why we do or do not find these impacts, and explored how social processes and social relations were affected by, and in turn shaped responses to, the programs. While many official evaluations now require mixed methods, and these have demonstrated policy relevance and impacts, there is still considerable progress to be made with respect to how methods are integrated in practice and how mixed approaches are appreciated in social program evaluation." from authors' abstractqualitative research, ethnography, survey research, mixed-method research, evaluation, conditional cash transfers, heath, nutrition and education programs, Social protection, Targeting, Gender relations,

    Building on the value of Victoria’s community sector

    Get PDF
    Building on the value of Victoria’s community sector goes beyond the sector’s economic contribution. It discusses the value of all Victoria’s community sector organisations, including those operating with registered charitable status and those operating without. The paper also outlines broader aspects of the community sector’s value than just the economic. These include the sector’s unique ability to amplify the voice of people facing disadvantage and build relationships with those who most need support, its diversity, its innovative and collaborative nature, its focus on prevention and early intervention, and its ability to build community cohesion and wellbeing. While outlining these, Building on the value of Victoria’s community sector also outlines ways in which this value can be further built on, to generate even more benefit for people and communities facing disadvantage, and Victoria as a whole

    Design effects for multiple design samples

    Get PDF
    In some situations the sample design of a survey is rather complex, consisting of fundamentally different designs in different domains. The design effect for estimates based upon the total sample is a weighted sum of the domainspecific design effects. We derive these weights under an appropriate model and illustrate their use with data from the European Social Survey (ESS)

    Supervised regionalization methods, a survey.

    Get PDF
    This paper reviews almost four decades of contributions on the subject of supervised regionalization methods. These methods aggregate a set of areas into a predefined number of spatially contiguous regions while optimizing certain aggregation criteria. The authors present a taxonomic scheme that classifies a wide range of regionalization methods into eight groups, based on the strategy applied for satisfying the spatial contiguity constraint. The paper concludes by providing a qualitative comparison of these groups in terms of a set of certain characteristics, and by suggesting future lines of research for extending and improving these methods.regionalization, constrained clustering, analytical regions.
